Earlier this week I was sipping wine late at night and cogitating on what led me to where I am now. Part of that was the more specific topic of what, or rather who, influenced my technical development and career, especially early on. As a little game for myself, I decided to jot down the 10 first names I came up with and did not discard within 5 seconds. And then excluded those who’s influence had been negative!

The ones you will know…

It’s OK, don’t get your hopes up, you are not on the list.

That list was:

  • Cary Millsap
  • Craig Shallahamer
  • Mike Cox
  • Jonathan Lewis
  • Barry
  • Maria Colgan
  • Steven Feuerstein
  • Rachael Carmichael
  • Tim (OracleBase) Hall
  • Dominic Giles.
  • Richard Foote

I really hope you have heard of most of them. I’d be amazed if you know all of them. And yes, there are 11. I was, if you remember, sipping wine late at night. In the morning I looked at the list and thought about refining it or expanding it (and boy, I could expand it to 50 people plus in 10 minutes) but that was not my game. First 10, with very little analysis.

You know what is coming, I’m going to step through the list. I’m so obvious. But the reasons are not always so obvious (though some are, sorry). Remember, I was slightly drunk.

Cary Millsap. I detest Cary Millsap.

I’m joking of course! But a tiny little bit of me always goes “Grrrr” when I think of this man who is fundamentally a really nice person, very bright, and a wonderful presenter. Why? Well, he came up with OFA, the Optimal Flexible Architecture. This specified a logical, sensible way to lay out an Oracle database, it’s files and the directories they went in, file naming conventions etc such that the database was performant, easy to navigate, and you could have multiple databases on a server without confusion. And that could have been me! I came up with almost the exact same thing and I was damn proud of it. And 6 months after I came up with it and thought “I need to make a big thing of this and get some credit for my genius” – I came across OFA. I was gutted.

Optimal Flexible Architecture 8.1.5 style

The thing is, Cary was one of the first people I came across who was putting out stuff to help all us DBA types back in the 1990’s.  I am sure I must have seen stuff he did that became the OFA and it influenced me. His OFA was first published a couple of years before I came up with my design, but I had not seen it. We did not really have the internet back then!

Cary did not influence me simply by producing great stuff, he made me realise that several people can come up with similar ideas and, actually, being “first” is nice – but really the key thing is to spread the knowledge. Making our jobs easier for everyone around you is really doing something for the community. Cary also came up with Method R for performance tuning which is great, but time to move on.

I sometimes mention I have a decent dose of dyslexia. In my mind Craig is Craig “Shalamar”. His last name is too long for me and I “spin” in the middle of his surname “Shallahamer”. Too many repeated letters (in my mind there are 2 m’s too). Thus when I only knew him from printed materials my brain would stick with the wrong name. Few people were putting out stuff in the early 90’s and because his stuff was so good he was a key, early source of received wisdom for me. Then in the late 90’s he disappeared, or at least from my view he did. But now he’s back and I’ve met him. He is about the only person (him and Kerry Osbourne, sorry Kerry) who I have been a little hem-touchy with  (go right to the end of that post). ie went “Oh wow! You are blah blah!” when meeting them (follow the link if you want to know what I mean). It’s OK, Craig let me off. I got him a beer. It was a free beer, it was at DOAG! One day I’ll actually buy him a beer to say thank you for all the help he gave me early on. I might even buy him two, but let’s not get too giddy.

Mike Cox is fundamentally a brilliant developer & incredibly smart and he will never, ever present. It’s not for him. He represents the huge number of very talented I.T people you never hear about as they just get on with the job. I worked with Mike when I was at Oracle in the early 90’s and again at the end of the 90’s when he {grudgingly} told his boss I was not totally useless. His boss knew that was high praise. I remember someone telling Mike his code did not work. Mike replied “Yes it does! I’ve checked it. Twice!”. His code worked. He is one of the few people I know who can write a page of PL/SQL and execute it and it does what he wants, first execution. But that is not what he taught me. He taught me that what we do is create solutions and the absolute one thing you have to do as a developer is create something the user wants to use. I.E. it makes their working life easier. Everything else is secondary. Thanks Mike.

Sharp tools – everyone here is one

If you are in the technical core Oracle RDBMS sphere and you do not know who Jonathan Lewis is, I’m stunned. His approach to methodically understanding problems and how Oracle works is second to none. I think there are one or two people as good as Jonathan is but personally I know of no one better. So that is why he influenced me? Well, yes and no. Oracle Names, those top people (and this is true in all disciplines) are people, just like all of us. Very talented but, fundamentally, normal people. Jonathan is a friend, I like chatting to him in the pub and we will discuss bread and chainsaws on twitter. And he has given me advice and help over the years, as a friend, and I very much appreciate that. And if it is not Oracle, sometimes I’m teaching him. If you meet those presenters and writers of good stuff then yes, of course, respect their skill. But don’t hero worship them. Most of them don’t actually like it. Treat them like regular people (because they ARE regular people) and you might make a friend.

I’ve written about Barry before (and no, I can’t for the life of me remember his last name). Barry taught me that you don’t need to be technically the best to be great at what you do. You need to care and you need to be willing to try and you need to be willing to learn. It’s all about attitude. In the little team we were in we had a guy who was technically superb. And no one liked him, as he was an arrogant and unhelpful bugger. Everyone liked Barry and asked him to help. Be like Barry. I try to be like Barry.

SQL Maria (She’ll probably never lose that nick name in the Oracle sphere) used to the product manager for the optimizer and I was a performance nerd, so of course I knew of Maria Colgan. The number of times she said to the audience “I’m not technical, I don’t understand this stuff…” and then gave a really good description of that stuff. She was a little liar! She knew her stuff (and still does), you can’t present like that and not know your topic. She was also one of the first product managers in Oracle I started chatting to, both about technical topics and as a friendly face. Oracle Names are just normal people and Oracle Names From Oracle are just normal people too. Who knew? Maria now looks after In Memory and stuff like that, but if you google her, the top hit is still “Maria Colgan Oracle Optimizer”. I wonder if Nigel Bayliss, who has been the PM for the optimizer for a few years now (and very good he is at it too) has a doll in a drawer with pins in it…

Well worn indeed

Steven Feurestein. I can’t spell his last name best out of three due to the aforementioned dyslexia. Anyone, and I mean ANYone, who was coding in PL/SQL in the mid 90’s onward probably had/has the Ant Book on their desk, Oracle PL/SQL Programming by Steven. I consumed the first edition of that book, pretty much working it to ruin as I referred to it over the years. I still have it and boy it is tatty. Thanks for that book Steven, and the ones that came after it. However, Steven has influenced me twice. He now works for Oracle, leading the Oracle Developer Advocates team which includes the Ask Tom team. And that’s sort of what I do now, advocate Oracle and the community. Only I don’t really get paid for it. Can I have a job Steven?

{Why did I not pick Tom Kyte? Looking back now he was a massive influence on me as he was on many others, he should be in the list. But he isn’t. So aren’t a lot of excellent people like Arup Nanda, Chris Antognini, Kevin Closson, Uwe Hess…}

I thought I had written a blog about Rachael Carmichael but it seems I have not. Rachel was really active in the Oracle presenting circuit back in the 90’s and early 2000’s and wrote/contributed to several books. I met her at one of my first UKOUG conferences when I was a presenting newbie. Rachael sort of took me under her wing and not only gave me good advice but also introduced me to several of the really well know presenters, a lot of who were in the Oak Table. Both of those things had a big influence on my career.

Rachael then decided she’d had enough of technology and followed a different path and swapped to working with animals. Because she wanted to. You can change career totally – if the current one has lost it’s sparkle, go find something else to do. I did not leave the Oracle sphere (I thought about it) but I decided to stop being mostly a technician and more an enabler, encouraged by Rachael’s example.

 

Tim blogs as well as writing articles

ORACLE_BASE must be one of the most visited and highest quality sources of Oracle technical information on the web. If you did not know, Tim Hall writes it all (I think he writes it all. Maybe he has a team held captive in his basement. I’ll ask him). If I need to check syntax or how a feature works, I google it and if an ORACLE-BASE page comes up I go there. Tim’s a great guy and a very good presenter – but don’t let him near an Oracle panel session. And oh boy don’t let him sit on one! Like me he is a biologist really, so an absolute top, fantastic bloke :-). Tim also has a very philosophical outlook on this Oracle technology bollocks, which I am sure encouraged me to do my Friday Philosophies.

Dominic Giles is a Master Product Manager for the Oracle Database here in the UK. I don’t know what you do to become a Master product manager, maybe just get old? For years Dom has been a real friend to the UKOUG and the conference circuit in general, doing great talks about the core RDBMS, what is new, what can and cannot be done. But the reason he really influenced me is he came to help us when I was working on the human genome project. Most consultants going on-site for a company would never tell the client to “just grow a pair and do it Martin”. Dom did. Bloody brilliant. We did know each other quite well at this point and it was a kick up the arse I needed. Be real with people, it’s so much more effective (if perhaps a little more risky?)

Unfortunately, Richard does not look like this anymore

Finally, and well done for reading this far, is Richard Foote. Actually, I reckon almost no one will have got through this whole list, my wife keeps telling me to split this post into 2 or 3 parts. But Richard will get this far, he wants to know what I say about him and if it includes anything about David Bowie. Richard is a bit of a Bowie fan, as am I. Bowie’s “Black Tie, White Noise” is playing as I type this. What Richard does not know about indexing you don’t need to know. I learnt a lot from him. But then I learnt a lot from many people, so why Richard?
This blog. I stole his layout for mine. In fact, before I changed the graphics for the banner and stretched the format it looked EXACTLY like Richard’s blog. Also, I liked Richard’s presenting style – Relaxed, jokey, but with good technical content. I sort of nicked that too. Part of me just want to be Richard, except for the being Australian bit 🙂

Well done, that’s the lot.

 

OGB Appreciation Day: It’s All About ME! October 10, 2019

The Oracle Groundbreakers program, and it’s previous incarnations going back to OTN and beyond, are all about me. Yes – Me!

What a great bunch of people

Well, having hopefully got you hooked in with the ego-laden title and first line, let me explain.

As OracleBase (Dr Tim Hall) describes in this post on Oracle Groundbreakers Appreciation day, today we are celebrating what OTN/ODC/Groundbreakers means to many of us. For me it is quite simple, Groundbreakers, as part of the larger Oracle community, gave me the career and roles I currently have. The knowledge, support, and community they promote made me into the President of the UK Oracle user group. Why do I say this?

Let’s go back in time a little, to the last millennium. When I was first navigating my Oracle career the user community sort-of existed back then. You had big, flappy, paper things called “books” that you could buy and put on your desk. They held loads of information and stuff you did not know. And those of us who were keen to learn would swap white papers and articles by email, which you would also print out and put on your desk, in an ever-growing couple of towers. Why all the paper? We had 14-16 inch screens with terrible resolution, you had no screen space back then, so you programmed on that and had your help on the desk. As for googling things – didn’t exist. At this time I was utterly on the receiving end of community. I was being taught. I did teach back then, but only face-to-face for whichever company was employing me at the time.

Step into the new millennium and I landed a job with the Sanger Institute and the Human Genome Project. The Sanger have a culture of sharing – data, techniques, information, discoveries. As a result I was not just allowed but encouraged to go and talk at conferences. So I did. My first presentations were at Oracle Open World, the Oracle Life Sciences User Group (OLSUG), and the UKOUG conference. Very soon I was helping run the OLSUG events and volunteering at UKOUG events. I just got sucked in. I was still of course on the receiving side of the community, learning from all those great people who present, write, chat etc. But now I was giving to the community too. And there was something about being part of the “giving” community that I had not expected. You learn even more. And you have more fun! I got to meet a lot of fellow presenters, event organisers, and product managers – especially when I was made an Oracle ACE and joined what is by far the largest part of the Oracle community.

The ACE/Groundbreaker program recognises not necessarily the smartest and best people in any given field. It recognises those who put time and effort into sharing, in helping others (which was lucky for me!). You have to know your stuff to teach others (so be technically or business good), but you also need to be willing to, well, teach! To interact with people. So the vast majority of people who are in the program are also friendly & supportive people. Being dropped into that group really helped me.

Not only did I meet all these people from around the globe, I’ve been able to go around several parts of the globe to conferences and meetings. Groundbreakers does a lot to support people going around the world to present and share knowledge. The great thing about travelling is you see other perspectives and cultures. I don’t think we realise how parochial our viewpoint can be until we meet people with different perspectives and experiences.

As a result of my being part of the community and being an ACE/ACED, I’ve continued to learn technically, I’ve got a lot better at interacting with people, my communication skills have developed, and I now know a lot of skilled people in the community. All of these things have of course helped my working career. But where it all comes together is in my role as UKOUG president. I would never have considered putting myself forward for this role if I had not had all this experience with the Oracle community. And I don’t think I’d be very good in the role if I had not learnt all the “soft skills” that I have, and made the contacts that I have.

So Groundbreakers, you made me President of the UKOUG.

I *think* I thank you 🙂

Friday Philosophy – Brexit July 26, 2019

I don’t really do politics on this blog, it’s often just too damned divisive. But not only am I angry (and vicariously ashamed) of Brexit but I have a strong suspicion of how things are going to go from now…

I’ll lay my cards on the table first. I did not vote for Brexit. Like the vast majority of people I get on well with in the UK, I wanted to remain part of Europe. Half of my anger with Brexit is that I feel there should never have been a public vote in the first place, for three main reasons:

  1. It has been heavily speculated that the issue of us remaining part of Europe was offered as a public vote as the Conservative party wanted to shut down the growing popularity of the more right-wing, xenophobic parties such as UKIP. Thus it was a waste of time, money, and effort to prove a point that I think could have been done in other ways. There was never any expectation by the people who instigated the referendum that a large percentage of the population would vote for leaving…
  2. Whether we are better off being within the EU and what we lose/gain from it is a very complex issue. I’d say 99% of the population knew nothing like enough about it to make a sensible decision. I think I understood more about the influence of the EU on us than the majority of people in the UK. This comes from me having an interest in environmental matters, workers rights, health & safety, and control of big business. An awful lot of our legislation in these areas came from the EU and were good for the majority and poor for the rich and powerful. However, I don’t think I had enough knowledge to make an informed decision, it was more a gut decision. And the political fight over the vote was almost devoid of sense, reason, even honesty, and was more a campaign based on fear, uncertainty, and doubt. It was a vote by the ill-informed on the ill-defined.
  3. The final reason is that our media and politicians have used the EU as a “distant enemy” to blame or ridicule for decades. It’s almost a national hobby. We had stupid stuff like claims the EU said we had to sell straight bananas or that barmaids would have to completely cover their bosoms. Neither were true. But there has been a consistent blaming of the EU for things that UK politicians thought would be unpopular or that the tabloids felt they could sell copy on due to outrage. It’s just like how businesses blame “the computer system” for anything that goes wrong (“Computer says No! – *cough* “) whereas in fact it’s often nothing to do with the computer system. Thus the EU already had an unfair bad press due to all this political cowardice and media tripe. In many respects, we reaped the crop grown from the seeds of our own stupidity.

Anyway, we had the vote, it was really tight, it gave “the wrong” result. And it seems that far more people have swap from “let’s leave” to “let’s stay” than the other way around, when they got a better understanding of the impact – but we are not getting a second vote. That is despite 6 million plus people signing a petition for a second vote and the biggest public protest march we have ever had in this country.

So what do I think will happen from here on in?

Something I have expected to happen for a couple of years now, but has not really, is an attempt by UK politicians to start trying to blame the EU itself for the mess the UK are in. Basically to start saying “Well, we could leave the EU and it would all be fine – but the EU are being mean to us! The EU won’t let us do X or let us have Y! Because they hate us now and they are not being fair!!!”. We are going to see an escalating number of occurrences where the Conservatives will tell us that the EU negotiators have blocked an utterly reasonable suggestion or are making demands that threaten our sovereignty, or are trying to control us. They will announce that the EU is trying to stop us being the great nation we know we are. I fear that Boris will start turning to Trump to be our best friend in the playground.  

From what I have seen so far, I think the rest of the EU have basically been “You want to leave? Are you mad? OK, if you wish, off you go. But I’m sorry, if you are leaving the club you no longer get the club discount at the shops, you no longer have access to the club house, and you don’t get any say in the club rules. And yes, you do have to pay your outstanding club membership until you actually leave.” Which is all very, very reasonable and, if tables were turned, it is what we in the UK would be doing.

I predict that from here until Boris and the Tories do whatever they do in respect of our fundamentally xenophobic “we are still a mighty empire and are too good for you” walking off in a huff, more and more they are going to try and blame the innocent party, the EU. We are going to hear endless stuff about how they won’t be reasonable in negotiations and are bullying us. I don’t think the EU will do that, but really it’s what we actually deserve for our childish behaviour.

First Lessons, Frustrations, & Funny Stuff – Introducing the iPad To My Mum July 12, 2019

<< Introducing I.T. to an Elderly Relative
<<<< Preparing the device

So, you are are helping an elderly relative or someone else who knows nothing at all about keyboards, icons, internet, or web browsing to get going with I.T. You have set up the device for them, now you need to introduce them to it. This is where it gets… interesting.

As I describe in earlier posts, I bought an iPad for my mum and set it up in a nice, simple way for her. I knew there was nothing she could do to actually break the iPad, it would just be a little confusing and possibly quite a frustrating process showing her how to use it. I was wrong. On all counts.

To do this I drove up to see my mum for the day, taking along the current Mrs Widlake for emotional support. Having arrived and set up the new router we had got from British Telecom (that’s a whole other story of woe) I sat Mum down and showed her the iPad, the on/off button, the volume buttons and the Home button. I got her to turn the device off and on, I pulled up some things on the internet to show her videos & music and got her to turn the volume up and down, and showed her how you touch the screen to do things. I told Mum about plugging it in and the icon that shows how much charge it has. All was going OK. I showed her the keyboard…

“Ohh, that’s complex!” No it’s not, there is one key per letter and some special keys. “Why can’t it have 9 numbered buttons and you just press 3 twice for H?” Because it is not 1995 anymore and this is much easier. I open Messenger for her, start a conversation to me and get her to type, yes you guessed it, ‘Hello World’. “I can’t find the ‘L'”. That’s OK, just take your time…

Mum is punching her finger on the screen as if she is killing cockroaches. You just need to tap it mother “I am!”. More softly (bash bash bash). No, gently (bash bash). If I poked your cat that hard she’d bite me, imagine you are touching the cat (bash bash bash). Mum, the screen is glass – if you hit it like that it will break and cut your finger off! That worked.. sort of (thud thud thud). 2 minutes and liberal use of the delete key later (her aim is poor) we get ‘Hello World’. Great! Well, you are sending the message to me, look that’s my name and a little picture of me! Say ‘Hello Martin’ – “Hello Martin” says Mum. Nooo, type it. “Where’s the L key?” Same place as before, just take your time…

When Mum is looking for a key she hovers her finger over the keyboard, waves it over one area, goes to another area and waves it over that – and then back to the first area… and repeats. Half of the keyboard has some sort of exclusion field around it. Mum, just look along each row until you find the letter you want. “I was!” No, you looked there and then there, 3 times. Trust me, just work along each row. She does.. “There it is! I knew it was there!”. Hmmm

After about 10 minutes of this random messaging (it felt like an hour but my wife, sniggering on the sofa, said it was 10 minutes) I get Mum to practice logging into the device. This, after all, is a vital step.

I tell her the password is my name. I decided on my name as she (probably) won’t forget it and it is more secure than a number that she will remember. “With a Y or an I?” Huh? “Martin with a Y or an I?” What did you name me? “Martin”. With a Y or an I? “Well, an I of course.” Well it’s with a bloody I then! “Some people spell it different…”. Why would I set your password to my name but spelt the wrong way? It’s an I you silly old Moo. (yes, it’s getting to me).

She types Marti.. “There is no N key”. It’s there. “Oh yes”. I tell her to press DONE. She does, the home screen comes on. I get her to turn it off and put in her password again. “What is my password?” Martin. “I just typed that”. Yes, we are practising. “OK – (thud thud thud… thud….)”. The N key is there, Mum (thud). And DONE… (thud) “I’m in!”. Excellent. Now do it again so you have done it without any help.

(thud thud thud….thud…..) “The N key has gone!” – It’s…  {breathes a little…} there! “Oh yes! I knew that!” But she does press DONE on her own.

Now do it again. “Why?” Because I need to know you can do it easily. (thud thud…thud thud…….) “Where…” It’s there! There! THERE!!! You’ve pressed it 4 times in the last 2 minutes, it’s ALWAYS there, it does not bloody move!!! IT’S THERE!!!! I can feel veins throbbing at my temples…

Sue pipes up “Shall I make us all a cup of tea and we can go look at the fish in the pond?” She’s a saint.

After a break and some calming down, we go through it all again (with fewer issues and less swearing) and I show Mum ‘Messenger’ again and how she can communicate with me. I show her how to type a message and send it and how to call me and we do a few trials and she seems OK with that. She keeps forgetting to press the plane icon “why is it a blue arrow?” It’s like a plane, you send the message. “It looks like an arrow”. OK, it’s an arrow, you are firing the message to me wherever I am. “How does it know where you are?” Magic Pixies.

By now we are both getting really annoyed with each other but she can turn the device on, log in, use the keyboard (well, sort of) and she can message me. That is enough for day one – and I need alcohol in a way that is slightly worrying.

We drive home and later that evening we get a message off my mum. It’s almost indecipherable as she has forgotten where the delete key is, and she does not seem to understand that she can check what she has typed, but it’s sort-of a success. I started to reply about where the delete key is, but something in my head steps in and quietly suggests to me that remote support for my confused mother after all the wine I consumed is probably a poor idea. I send a brief “we got home” message – and a picture of a cat.

Next day she calls me on Messenger. Hi Mum, how are you? “{small scream} – is that you, Martin?” Yes, you called me. “No I didn’t!” Err, yes you did. “I didn’t, I sent you a message”. Did you press the blue arrow. “Yes!”. The one next to the text you typed “No, the one at the top of the screen”…. At the top of the screen?… Does it look a bit like a telephone? “Yes!” That would be the telephone then. “Oh! How do I send this message?” After I end the call mother, press the blue arrow. 30 seconds later my phone rings. Hi Mum… “(smaller scream) – it did it again!” So, why do you think it did it again? “I pressed the wrong key?” Yes.

Over the next few hours I get a few messages (no more calls) and slowly the random strings slowly become things I can understand. We are getting there.

She Bricked the iPad

Next day she calls me on Messenger… Hi Mum? “{small scream…}”  We repeat the previous day. Typing is better.

Next day, no call, no messages.

Next day, no call, no messages.

Next day, the phone (real phone) goes “I’ve broken it, it won’t work!” Hello Mum. OK, what is broken. “It’s broken, it won’t let me in! It won’t accept my password”. OK pick up the device tell me what you are doing… We work through it, she is entering the password (with an I not a Y, I checked) and “it’s not working” is actually she is getting a message saying the device is disabled. I ask Mum if maybe, perhaps, she got the password wrong a few times and it asked her to wait 5 minutes before trying again? “No, I got my password right – but it would not let me in and after a few times it said that!”. OK… So, leave it alone for an hour and try again. “I did that yesterday!” I’m getting a bad feeling about this… ” And after I tried it, it told me to wait again… and it still could not remember my password and then I left it all day and now it says it’s disabled and needs to be plugged in. I plugged it in!”

I explain that she has actually done the one thing that can brick(*) an iPad. She has repeatedly got the password wrong enough times and persistently enough to cause it to believe it is stolen. It is useless to her. It needs to be plugged into a computer and reset. *sigh*. I asked her why she did not call me when “it forgot her password”. She did not want to bother me…

So now I had to organise a day to drive over there, factory reset the damned thing, and set it up again. And I was going to change her password to a simple number.

It had not been a little confusing, it had been utterly baffling.  I had not found it quite frustrating, I had been turned into a swearing lunatic. And she had indeed broken the iPad.

I rang my Brother. I told him the inheritance is all his – I am adopted.

(*) Brick – turn an electronic device into something as responsive and useful as a house brick.

Preparing A Device for Someone New To I.T. April 26, 2019

In my previous post I covered what I felt were the main considerations on deciding how to get someone with no real experience of I.T. online, for an example an elderly relative like my mum. In this post I’ll cover setting up the device.  Set-up is actually quite complex and there is a lot of assumed knowledge, like how the keyboard works, what spyware you leave turned on (none!) etc. So I am setting it up for her.  First I’ll just recap the main points on why I decided to use an Apple iPad for my Mum:

Keep the main screen as simple as possible

  • A small tablet – but not too small.
  • Simple, intuitive interface.
  • A Smartphone or iPad mini was too small.
  • PC/laptop ruled out as too complex for her.
  • Apple device as her main potential contacts use Apple devices.
  • A lack of remote access by me was less important than the above considerations.

On of the first things I did was to ask my friends (via Twitter) what they would suggest or had found worked when they had a similar task. Thank you to everyone who replied. If you have further advice, add a comment or contact me and I can update this post. The main suggestions were:

Keep It Simple

Mum has never used a keyboard, never used a smartphone and is not very technically adept. Everything she is learning is almost new to her, from what the enter key does to what an icon is. The closest reference I can use for her is the menu of options on her TV recorder – and she has some pretty bizarre ways of using that (but if it works for her, that’s just fine). So using the device has to be very, very simple. I want the main screen to be simple and non-threatening:

  • Remove every App that is not for something she needs to use (or I need to help).
  • Move any icons I need but she does not (or at least not at first) off the first screen.
  • Be brutal, delete as much as you can –  you can add back anything you later find you need.
  • Only have one app for a given task. Choice in this case is probably just confusion.
  • Include one or two (and only one or two) key things she will want to use.

I’ll just cover some of those bullet points in more detail:

Remove every app not required. My mum has no interest in stocks & shares, in monitoring her health, in maps of where she is (she knows where she is, she does not go anywhere else!). She certainly has no interest in “iTunes Store”, “Photo Booth” or any of the other “free” apps provided by the vendor. They will just be confusing clutter at first.

If there are 2 dozen icons on the screen, Mum will worry about what they all do or what will happen if she clicks the wrong one. And she will click the wrong one. It is a worry we don’t need.

When she first starts, she will struggle to find the right icon – even from a simplified list (and she did). The fewer choices the better.

So I deleted absolutely everything but the half dozen things she needed. If in the coming weeks, months or years she wants anything a deleted apps provides, they can be added back. When she is comfortable with the first lot, I can introduce more.

The very basic “what the buttons do” help sheet

Move Icons I need to the second page. There are some things I need to get the device all set up for her and then tweak it. Two of them are “Settings” and “App Store”. You could argue that “Settings” will have things that Mum might like to change. But she won’t know how and she could mess up things if she changes her settings. So they are moved to the second page – and I told her to leave that page if she ever gets on it! The chances are she will not find the second page of Icons. (I did show her how to get off it, but stressed she call me if in doubt).

I also put a couple of things on the second page that I think she might want to use soon.

Only One Way.  I was advised to provide Mum with e.g. two ways of getting hold of me, in case one fails. Well, no. I do NOT want to have to show her two messaging apps and teach her the differences, I want one method that she can become confident with. It’s part of keeping it simple. Mum will be challenged to learn one interface, if I try and show her a second she will get confused over what works in which app. She can call me on the phone if the new way of communicating is not working, she is happy using a phone (as in just a phone, one that only makes and receives calls).

If Mum decides she does not like the app I choose (e.g. BBC News for, well, news) we can swap later. But right now I pick what I think she will like. And for the sake of simplicity, I chose a set of apps that are from the same provider, so work the same way.

We in the I.T. profession often love that we can swap between programming languages or have 4 or 5 social media apps to choose from. But we live and breath this stuff. This is all new to Mum. When you learnt to drive a  powered vehicle you learnt to drive a car. Or a motorbike. Or maybe even a tractor. You did not learn to use all three at the same time – and also an articulated lorry at the same time!

One or Two things she wants. I got a lot of advice of things to add to make the device fun or interesting, such as games, picture editing, or puzzles. The principle is good – but the reality is you need to think about the person and what they want from the device. And the keeping it simple aspect.

My mum loves jigsaws – but she loves the physical side of them! She has her tables set up, she talks about the manufacture she likes as the pieces fit together so well, she likes to glue together the occasional jigsaw she really likes. Maybe in the future she will look at Jigsaw apps, but right now she wants to keep her physical jigsaws.

What she wants is (1) a way to communicate with me (2) information on cycling and Formula 1 (3) the weather. So I gave her them. Nothing more, I’m keeping it simple. So that is Messenger, BBC sport and BBC weather. BBC news completes her intro to the web.

(Note, I also tried to introduce searching for things on google, but it did not work well – google does not understand “I want to know about him, that cycling chap, the one who’s not got side-burns”. We will come back to google in a month or so).

Make it Big and Bold

I don’t know about you, but the last time I changed my smartphone I got one with a slightly larger screen as I was having to hold the old one further and further away from me so I could focus on it. And I set my new smartphone to have larger Icons.

Add pictures they will like to their social media and the device. Keep personal information to a minimum to protect them.

If you are new to I.T. and you are starting to have issues with vision or hearing, there are options for any device to make it easier to use. Check out the “Ease of Use” or “accessibility” options of the device. Ironically, they are not always the easiest to find. For iPads they are not a main option but under “General”. That’s not very helpful, Apple!

You maybe don’t want to bring up the topic of failing faculties with an older relative – so don’t. Just set up the device to have large icons, big text. and loud messages. Big and Bold.

Also, think of adding pictures and sounds the person will like. I changed the iPad wallpaper for a picture of our cats and when I created her facebook account (hmmm, I’ve not covered that…) I added a background of myself and my brother up some hills and a picture of our last cat as her image. I would have made it a picture of one of her cats but I did not have one. And that will be a nice thing to do with her sometime. The main thrust is use images the person can relate to.

To make the device easier for Mum to use I considered the following:

  • Increase the text size.
  • Increase the icon size.
  • Bold text & increased contrast can help if vision is poor.
  • Set the volume loud and make sure one of the first things you demonstrate is how to increase (and decrease) volume.
  • When you start messaging, send pictures. It’s more interesting.
  • Show them emojis. My mum seemed to really like emojis. Less Tyoing!
  • Put pictures they will like as their wallpaper and social media images.

I think I could have done more in this respect. What I should have done was got pictures from her and scanned them, or looked back in my old photo collection. I could have set the wallpaper to a picture of my Dad (long gone) or of all us kids or something. And any social media you set up for the person, think what pictures you can use for backgrounds and avatars.

 

Reference Material

The online help on tablets etc is pretty good – once you are able to look for it and learn what you can ignore.

For anyone who is really new to technology, reference material is going to need to be a lot more basic.

Keyboards Confuse the Uninitiated

I prepared several sheets of information for my mum, like how to use a keyboard, which I show here. I also did some pictures of the iPad and annotated it – and left space for Mum to add her own notes!

My Mum found these really helpful, especially being able to scribble on them herself (which sometimes was replacing my helpful text with her weird description on what a key did!).

As well as this, I got her one of those “a senior citizen’s guide to the iPad” magazines. They are a good place to go to once the real basics of how to turn the device off and on and how a keyboard works have been learnt. BUT, they have a big drawback – they try and show lots of things in order to address a wide audience, and they usually have a long section at the start about “setting up your device”. I already set it up, Mum does not need it. So, edit the magazine!

I went through the magazine and crossed out in big, thick, black lines the bits she did not need. I also crossed out those sections on an app I had not given her but did a similar thing, and wrote at the start of it “do not read, Mum! Yours works differently!”

 

Random Other Advice

“Tell her not to clean the screen with a brillo pad! :)”
Well, it was a bit of a joke but it leads to a serious point. Explain how to look after the thing. I made the point that she should not get the iPad wet and to dry it immediately if she does spill things on it. And, if she drops it down the loo, take it out immediately, turn it off if it is on and put it somewhere warm – and call me!

“Yes, you can leave it plugged in, it will work for several days between charges. No you can’t damage the screen by tapping it with your finger, but do not use a screwdriver. Hitting it harder will not make it work more.”

We should (and will) get a cover for it so Mum can hold it more easily. Her house is carpeted throughout so dropping it (which she does, but she is close to the ground) is not such an issue.

“tell her how to get rid of Siri when she accidentally starts Siri up.”
I have turned off Siri as much as I can. And this leads on to the general topic of telling the person what they can and should ignore.

I told Mum to ignore prompts she will get (“You have not backed up your device for a week, kittens will die!”) or requests for feedback or surveys; how to shut down advertising boxes; do not respond to anything that ask you to provide information or download anything. And, just because you now have a “computer”, you should still ignore any telephone calls you get offering to help you with your computer problem. They were a hoax before you had a computer, they still are – keep telling them you don’t have a computer.

“Be patient…”
That last one is key. This is all new to them and if you are a regular visitor to my blog you are probably an I.T. expert. It can be very hard for us to understand how new this is for non-I.T. people and we assume knowledge. Like, what the enter key does in different situations and using the shift key (a single press of the shift key is different to a double press – and undoing the ALL CAPS of a double press only take a single press, which my Mum rightly pointed out is not logical!).

My mum really, really did not understand the keyboard very well to start. But touching the screen and dragging things around she took to straight away. I guess different people take to different parts more easily.

Be prepared to be very patient (*) and do not be surprised if some things take them an age to understand and yet other things they seem to get immediately. At some point, probably very early on, they will find out how to do something you don’t know!

Friday Philosophy – Despair of the Dyslexic Developer and Your Help Please June 1, 2018

Posted by mwidlake in development, Friday Philosophy, Perceptions, Private Life.

Like a surprisingly large number of people, I’m dyslexic. I’ve mentioned this before, describing how I found out I was dyslexic and also how I think it is sometimes used as an odd sort-of badge of distinction. I am mildly dyslexic, the letters do not try to “merge or run away” from my eye, if I hit a large word I am unfamiliar with I can visually chop it up and get through it. But that is just me. So, today, I want to ask you all, if you are a dyslexic developer or know one, are there any steps you have taken to reduce the impact?

I should mention, neither Jim or Richard are dyslexic as far as I know!

A recent, slightly jokey, conversation on twitter reminded me of the issues I have had in typing the wrong thing (over and over and over again – my usual example is how often I have tried to “shitdwon” an oracle instance). And that in turn reminded me of a more serious conversation I had when at the OUG Ireland conference back in March.

As a developer, I sometimes struggle to spot spelling mistakes or use of the wrong (or missing) punctuation in my code. As my friend JimTheWhyGuy said in the twitter conversation, spotting you had spelt UDPATE wrong. I was telling the audience that I was something of a slow developer, partly due to dyslexia. I can stare at code for ages, especially if I am using a new construct to me, not understanding why I am getting an error. It is often not a syntax problem but a spelling one. I had real problems with the word “partitioning” (and still do) when I started using that feature. – it is a little long and has almost-repeated sections in the middle and I “spin” in the middle if I read it or try to write it. It’s a little too long for my wrists to learn to automatically tap it out.

After the talk a lady came over and asked me if I had any advice on how to reduce the impact of dyslexia when writing code. She’d been diagnosed at school and so had grown up knowing she was dyslexic. (I was not diagnosed as a child, which oddly enough I am still glad about – as I learnt to cope with it in my own way. But I am NOT glad I am dyslexic). I do not know what support and advice she had been given through school, but it was obviously still something that impacted things. All I could come up with were a couple of tricks I use.

One is to copy text into MS Word and see if it highlights anything. You have to teach your version of MS Word (*other word processors with spell checkers are available) that the normal syntax words are real, but all the punctuation and special characters get in the way. Where it does help a lot is reducing the number of errors in specifications & documentation I produce and, now, articles I write. But as I know most of you who come by here have already realised – spelling errors that give another correct word are not picked up by a lot of spell checkers, such as this WordPress site. My blogs are full of missing words, wrong words and other crap.

The other major advance is the use of, Software Development Tools (SDTs – and YES, I spelt SDT wrong first time around writing this!) or Interactive Development Environments (IDEs). These highlight syntax errors (so highlighting typos), allow auto-completion of command words and provide common code constructs. They help, but I’ve never been that good at getting the best out of them. I use SQL*Developer more than the others and it does help.

The final other thing is that I just factor in that it’s going to take me more time to write or read stuff. Like many dyslexics, there is nothing wrong with my comprehension (I went off the scale for reading age when I was 12) but it takes me longer and is more effort.

Looking around on the web about this, there is a lot of stuff, the above point about IDEs being a main one. One common thing is to use different fonts to help stop letters skipping about or moving, but I don’t have that sort of dyslexia so I’ve never looked into that. I was going to review the topic of dyslexic developers more before putting this article together, but reading it all was taking me too long! That and I found the constant “It gave me an advantage” to be bloody annoying.

So, knowing a few of you out there are also dyslexic to some degree or another, have you any tips to share? If you have something to share but do not want to be identified, contact me directly.

I’d really appreciate it, if not for me then for if ever anyone else asks me how I cope as a dyslexic developer.

My main opt-out of course was to move into performance. It’s somehow more “pictorial” in my mind and you write less code…

Friday Philosophy – Not My Cup Of Tea March 16, 2018

A few days ago I tweeted a copy of a “motivational poster”. I don’t normally like motivational posters but this one struck a chord with me as it was a lesson I took a long time to learn. Not everyone will be your cup of tea. Which is a very British (I think) way of saying you don’t like something or someone. “Ohh, that Mavis, she’s just not my cup of tea!”.

As I’ve got older, my thoughts on how we do or don’t get on have changed, as I describe below. I’ll say what I think now and where I came from. I think over time I’ve moved from a position of thinking we should all like each other and to not do so is a failing, to more that we won’t all like each other but it’s far more important how we deal with that.

Not everyone in this world is going to like you. No matter what you do, how reasonable you are, the number of olive branches you offer, some people are just never going to like you. That bit I learnt early at school when Nigel was leading the bullies. Each one of the bullies I could manage on their own, negotiate some peace, but not Nigel. Nigel was determined to always keep up the antagonism, no matter what I did. Over time I realised it’s just a reality: some people will not like you and sometime there is no discernible reason. And sometimes it can be a very passive dislike – no anger, no hate, just a total absence of like rather than actual dislike I guess. This was not the case with Nigel. The underlying reason he led the bullies was because if they were bullying me – they were not bullying him.

You are not going to like everyone. This is not a case of you needing to be a better person or some sort of saint, I don’t think I’ve met anyone yet who likes everyone. Some people respect everyone, have time for everyone, will try to think the best of everyone. But not like. I did not like Nigel, for good reason, but there are other people who I do not like who have never done anything bad to me. Again, it is not that I dislike them, I’m just indifferent or mildly irritated by them. For many years through my 20’s and 30’s I thought I should try and alter that – but I failed. I just don’t like some people.

It’s OK and Normal that some people you will just not get on with. I struggled with that for years. Surely, so long as someone is not psychotic or just simply a bad person, bridges can be built? When I started thinking more about teams, managing people, getting people to work together, I did learn more about how to identify the reasons for bad feeling and resolve them. I had more success at it than I thought I would. I also found that acknowledging that half the time it was my fault not theirs helped. But with some people, no it was not happening, we did not like each other. But things could usually be improved – if not bridge-building, then at least waving politely at each other from our respective sides of the river.

That led me to what I felt was the final part of being someone’s cup of tea. I like tea with sugar and milk, some people think that is disgusting and, anyway, it should be green tea. They are wrong. But it does not matter. If they want a cup of tea, green tea, I’ll make them a cup of green tea. This is a trivial example of a larger lesson:

Not getting on with someone is not a problem – so long as you don’t MAKE it a problem. If you don’t like someone or simply do not agree with someone, there is no need for you to make them “The Enemy”. If you do, well you just made an enemy and that person is likely to be obstructive to you, retaliate and generally make life less nice. And that will spill over to others around you. Oh, I’m not a saint, I try to apply this rule to myself but I don’t always pull it off.

I’m not wise enough to know all the reasons we do not all get on but I think sometimes the reasons are just not important. I might remind you of someone you really detest, I might find the way you keep singing bits of “The Smiths” an affront to good musical taste. And even if there are reasons that seem good, the less antagonistic you can keep it, the better. And I repeat, sometimes it is not active dislike, it is just an absence of like.

The context is also a factor in this. In a social situation, if you do not get on with someone it’s easiest just to avoid them. And we all do this. But you don’t need to try and make everyone else dislike them. In a work or family situation it can be harder as you have to deal with people you don’t like. I think that acknowledging that you just don’t get on and it happens, no blame either side, makes it easier to be equitable about it.

It seems to me that the people I do not get on with have a different life philosophy to me and the larger the difference, the larger the chance of dislike. I don’t like Right Wing conservatives. I don’t like selfish people. To them I am probably sanctimonious, deluded and borderline communist – which is not fair, I AM communist. In that I think our community is the most important thing about being human. But I also use humour a lot and that really annoys some people as I use it in inappropriate settings or they do not think I am taking issues seriously enough or professionally enough. And they may be right.

So, all very good and very grown-up of me so far. Now for my final point.

Some people are just not nice. We’ve all met them, the person who no one can get on with as they are so self-opinionated, bullying, harsh, self-serving. And any attempt to build bridges with them is either seen as weakness or used as a way to get you on-side before they hang you out to dry.

Is this just an extreme case of not being your cup of tea? Well, maybe, but I don’t think that.

Some people are just not worth the trouble. And some people are trouble.

It comes back to Condoning Bad Behaviour. I actually decided that some people are not nice (and probably never will be) long before I came to the conclusion about it being OK to not get on and trying to not make it a problem. At that point I wondered if that would be the whole solution, just accept that you do not get on and let it lie.

But I kept hitting up against the occasional person who, no matter how much you tried to not make it a problem, they did make it a problem. And they continued to bully, oppress, be antagonistic – and they got away with it. With these people I still try and walk away. And if I cannot? I don’t condone bad behaviour. I’ll tell them what I think and, if I can, I’ll stand against them. It is not easy though as they are like Nigel. They surround themselves with similar people or stooges they can direct. Now that is a totally different issue.

I think it’s right to try and be friends with everyone.
But you won’t be friends with everyone so strive for peace with the others.
And if peace is difficult, distance should work.
But I will not condone bad behaviour, OK?

Some people need to see me using this cup

Friday Philosophy – Explaining How Performance Tuning Is Not Magic? March 9, 2018

Solving performance issues is not magic. Oh, I’m not saying it is always easy and I am not saying that you do not need both a lot of knowledge and also creativity. But it is not a dark art, at least not on Oracle systems where we have a wealth of tools and instrumentation to help us. But it can feel like that, especially when you lack experience of systematically solving performance issues.

SQL statement be fast!

I recently spent a couple of days with a client discussing how you solve performance issues and I am preparing a talk on exactly that for the up-coming OUG Ireland conference on the 22nd-23rd March. The guys I was talking to at the client are very, very capable production DBAs, but traditionally the developers at their site initially look at any performance issues. If they think it is the database but not something they can fix, they throw it over the fence at the DBAs. It’s not always the database of course and, if it was a simple fix (missing index, obviouosly inefficient query), then the developers fixed it. So these two guys are expected to only solve the more difficult issues. That’s not really fair as, if you are not practising on the simple problems how are you supposed to gain the experience and confidence to solve the harder ones?

Anyway, a part of the discussion was about Explain Plans. What does the COST mean in the plan, they asked? They saw it as some number that in an undefined way gave an indication of how expensive the step in the plan was, but they could not link it back to anything solid that made sense to them. It looked like a magically produced number that was sometimes very, very wrong. Like most (good) technical people, they want to know the details of things and how they work, they don’t want to simple accept something as working.

So I took them through some simple examples of plans and of how the COST is just a result of simple maths estimating the number of IOs needed to satisfy the step.

I won’t go into the full details here but have a look at the below, this is how I started:

I explained how you read “down” the slope of plan to the end (so step 3) and then worked back up the slope. So the first thing Oracle does is the index range scan. I showed them the BLEVEL of the index, the number of blocks per indexed value and why Oracle knew it would, on average, need 3 IOs to get the leaf block entries for the provided “DOB=to_date(’08-OCT-1934′,’DD-MON-YYYY’)”. Each DOB matched, on average, 20 rows. So the cost of step 3 was passed up to the step 2 of accessing the table rows. This would be done 20 times so the cost was 20+3. 23.

OK, they could accept that, it made sense. So let’s extend it…

I took the original query against PERSON for a given DOB and now joined it to a second table PERSON_NAME. Why is not important, it’s just a demonstration of a simple table join:

Now I explained that as you work “back up the slope of the plan” from the first, most indented step (so from step 5 to 4 to 3) at 3 there is a nested loop joining the rows passed to step 4 to the step in line below it, i.e. step 6. They had already seen steps 5 and 4 in our first example, Oracle is expecting to get 20 rows for a cost of 23. Look at line 4. And for each of those 20 rows, it will do a range scan of the index in step 6 and for each row it finds in the index, collect rows from the joined table in step 7.

So for each of the 20 original rows it does a scan of an index on the joined table for a cost of 2 (I showed the stats to them how this cost is calculated) and expects on average to find 5 matching rows so it needs to do 5 IOs to the PERSON_NAME to get those rows. Add that together and that cost of 7 is done 20 times. 7*20 is 140, plus the 23 from the orginal scan of the PERSON table, the whole COST is… 163.

Light bulbs came on and they got it! My job here is done.

But it was not. I then went on to explain how it is now hard to get such a simple example. This one is, I think, from an early version of Oracle 11. I told them how histograms on a column will make the estimated cardinality (number of records per given value for a column) more accurate, but harder to work out. I showed them how the cost of a unique index scan is reduced by 1. I explained how Oracle was blind to the correlation of column values unless you took steps to tell the optimiser about it (you know, how for a given value of car manufacturer there will be only a few values of car model, the two values are related)…

Worry was creeping back into their faces. “so it is simple mathematics – but the rules are complex? It’s complex simple mathematics?!?” Err, yes. And with 11 and 12 Oracle will use various methods to spot when the simple, complex mathematics does not match reality and will swap plans as a result…

I think I lost them at that point. Especially when they asked about the SQL Profiles and how they modified Costs… Baselines controlling how plans are used… Bind variables…

That is a real problem with Oracle Performance tuning now. Even something as simple as COST is based on a lot of rules, factors and clever tricks. And they are not the only things controlling which plan is executed anymore.

So I took a step back.

I told them to accept that the COST is really, honestly based on maths, and the expected number of ROWS is too. But the actual, specific values could be hard to totally justify. And it is when the estimated COST and (possibly more importantly) the estimated ROWS goes wrong you have problems. So look out for ROWS of 1 (or at least very low) in a plan for a statement that takes more than a few milliseconds. And for very, very large COSTS/ROWS in the millions or more. And what really helps id if you get the ACTUAL ROWS as opposed to the ESTIMATED RIWS. Where there is a significant difference, concentrate your focus there. Of course, getting the ACTUAL ROWS is not always easy and is for a later (and properly technical) post.

So, they asked, if they could not get the actual ROWS and there were no 1’s or millions’s in the plan ROWS/COSTS? How did they know where to concentrate? “Well, you just get a feel for it… do the costs feel reasonable?…”

Damn – I’m not sure I really delivered on my aim of proving Performance Tuning is science and not magic.

Any pointers anyone?

(Update – Vbarun made a comment that made me realise I had messed up the end of this post, I was talking about estimated ROWS and still had the words COST there. Now fixed. And the other thing I was hoping someone was going to suggest as a pointer was – to split the query down to individual tables & two-table joins and *check* how many rows you get back with the where predicates being used. It takes some time but it shows you where the estimates are going wrong.)

Friday Philosophy – Criticism is Critical for Believable Endorsement March 2, 2018

If you had a friend who always told you that your were the best, that you had no faults, and that everything you did was great – would you trust them? I know I would not. I am fully aware that I am not perfect(*). I used to see this sometimes in relationships too, especially when I was younger. One of them would be so desperate for their boyfriend/girlfriend to like them that they would never criticise the light of their life. The relationship never lasted as it was, well, creepy and false.

Perfect In Absolutely Every Way

For your opinion of someone to be seen as honest, there has to be space for criticism. I love my wife very much, but she’s crap at loading the dishwasher. Joking aside, I believe my wife when she says she likes some aspect of my character as she will tell me about the ones she does not like. Thankfully, not at length.

In exactly the same way, for your opinion on a technology or application to be accepted as honest & worthwhile, there has to be space for criticism. I’m not saying that there has to be some criticism within any given endorsement of a product, I’m saying you need to be confident that the person would mention any faults or drawback they are aware of for you to believe that endorsement. I’m really hoping you are all agreeing with me on this!

So why do Marketing departments so often not get this? What is so fundamentally broken – OK, let’s be nice and say different – about their view of the world that any criticism is not acceptable? I just don’t understand either their belief that their product is perfect or that people will be fooled by an uncritical opinion of that product.

I can see how this would work in social media reviews like TripAdviser though. I recently did reviews of several places I had visited and a couple of companies then contacted me to ask me to remove the bits where I had said anything negative. They fundamentally wanted me to lie for them, or at least implicitly (and complicitly) give a better review by omission. I don’t take it well when I am asked to lie. In this case of social media I can see how “cleaning up” the reviews might help as most people look at the sum of all reviews and not at the reviewers.

But when you are actually a known person giving a review or endorsement, your reputation is critical to how the review is perceived.

What triggered this post was I recently discovered a friend of mine had been asked by a marketing person to remove some negative things they had said. They refused and made the point I have just made – if they were to be seen as believable when they said something else that the company produced was great, they had to be seen to be honest in criticising anything that was less-than-perfect. And let’s all be grown up about this, I’d say no software or application is perfect! However, the marketing person found this concept alien to them.

I wonder if people who work in marketing departments have difficulty maintaining long-term relationships? Based on my experience, quite a few of them are willing to ask you to lie for them and they don’t understand honesty is core to trust. Or am I just being very, very naive?

For me to trust the opinion of someone commenting on software & applications, in fact on anything really, I want to see some proof of their integrity by them being critical as well as complementary.

Friday Philosophy – Doing DOAG (& a Little, Light, Hem-Touching) November 24, 2017

This week I’ve been at the annual DOAG conference. DOAG is the German (Deutsch) Oracle User Group annual conference. This was my second time there and I very much enjoyed it, meeting lots of people & seeing some great talks. I also got a request to do more Friday Philosophies, so…

DOAG is now the biggest Oracle User Group conference in Europe, it overtook the UKOUG conference a few years back. Do I see this as “competition”? Well, a little bit of me does because for several years I was involved in organising the UKOUG tech conference – and a part of me would like “my” conference to be the biggest. But that is just misplaced, juvenile pride – really there is no competition between us. DOAG caters to the German Oracle User community (and nearby countries), UKOUG to the British Isles and, to a certain extent, Ireland and the closer parts of mainland Europe. If there is any competition then it is for presenters. I know that sometimes presenters have had to pick between the UKOUG and DOAG as they can only manage so much time doing these things. But I also know many presenters who do both. Also, both conferences are lucky enough to receive many more, very good presentation abstracts than they have presentation slots for. There will always be a great selection of presentations at both conferences.

There are some aspects of DOAG that I really do wish we could replicate for UKOUG. The first is the venue. Not only is the space they have at the Nuremberg conference centre so much larger and and better suited than the ICC in Birmingham, but it costs them “a lot less”. It might be outside of town (and Nuremberg is a nice town) whereas the UKOUG conference is almost in the middle of Birmingham, but at DOAG you get free transport as part of the conference pass. The second is the catering. The food at DOAG is very, very good; coffee is available at all times; you can get real, decent coffee at the venue (in the UK you need to go find a place that will sell you decent coffee); DOAG end the conference with beers and light snacks – the UKOUG conference tends to fizzle out.

But for me, though it is a close-run thing, I do ever so slightly prefer Birmingham and the UKOUG conference. I find it a little more relaxed (certainly there are less suits in evidence) and, on a personal level, I know so many more people there. I like knowing where the pubs & restaurants are and which ones are terrible! And somewhat ironically, our German Christmas Market is not only in full swing during the conference, but it is bigger than Nuremberg’s. But how many wooden toys, Gluhwein and sausage do you need in your life?

I did have a somewhat bizarre time with my presentations at DOAG though. First, I had to cancel a presentation. I was preparing a new one on the philosophy & process of performance tuning but due to some back pain issues (or rather the impact this had on my sleep and the pain medication had on my brain) I was utterly failing to get it done. So with only a week to go I had to ask if they could replace me. I hated doing it so late, I know what it is like organising these conferences and losing talks when you have printed the agenda is a real pain. Plus you now need to find a replacement. But I also know they would not appreciate a poor talk, so I let them choose. They chose to drop the talk.

But I honoured my other two presenting slots. The first was at 11am the first day and I experienced that thing that most presenters secretly like – it was so popular there was only standing room! As a result, the DOAG organisers asked if I would repeat it the next day or last day. Of course! However, as it worked out, they asked me to repeat it later that afternoon as one speaker was lost in transit. There was of course no time to really advertise the change. So I repeated the talk 4 hours later in the largest auditorium I have ever presented in – to 27 people. They of course were scattered around the room like lost souls. I guess it was using a room that would otherwise have been empty, and the session was recorded I think. But it did feel odd.

In between these two talks, I saw a couple of other people present. And in one talk, my phone kept buzzing. That was unusual, especially as it was a German number. I eventually exited (from the front row) and took the call. It was DOAG! They wanted to know why I was not at the interview I had agreed to do. “Because that is on Tuesday!”. Pause. The confused lady on the phone said “Yes. It IS Tuesday…” *sigh* – did I mention the pain meds and my brain? That was embarrassing. I had to go back into the room, to the front, get my stuff and wave an apology to Chris Saxon & Heli Helskyaho before scuttling off to this interview. Which I did very badly.

My final talk was interesting for other reasons. The talk was on calling PL/SQL from SQL and the impact it can have on performance and the point-in-time reliability of the results (if your called PL/SQL function itself runs SQL). I’ve discussed this topic with Bryn Llewellyn, the product manager (distinguished no less) of PL/SQL & EBR, in the past and I was able to catch up with him just before the talk. Then he came to my talk. I’m presenting in front of the Oracle employee who owns the tech I am talking about. No pressure. Then I look around the crowd and it is liberally scattered with other senior Oracle technical people, OakTable members, Oracle ACEs…

This is an unappreciated, small problem with becoming friends with these people. The bas…. good fellows and ladies come to your talk – and heckle.

Well, it keeps me honest and the heckling that did inevitably happen was all good-natured, and corrected a couple of slightly weak bits of my talk. So the crowd got a better talk than they otherwise would have.

And the Hem Touching? Well, go back a few years and we did not have the breadth and diversity of information the web now provides for us. In fact, we are talking back in the 1990’s when there was nothing like google and blogs and Oracle Base. What information was out there for Oracle was much more paper-based (you know, actual books & magazines!) or the odd word document that was emailed between people. One name I saw on such things quite often and who taught me an awful lot back then was Craig Shallahammer. Well, Craig was at DOAG, I’d seen him in the crowds once or twice. And after this talk he came up for a quick chat. I might have been presenting now for a good few years and met many of the best known people in our world of Oracle and I’m generally immune from the desire or need to go “Oh! You’re xxx! I’ve read all your papers!!!!”. But I did a little with Craig, as he was from my “Oracle childhood”. And he was very nice about it.

So all in all, an excellent few days. I’ll try and come again next year. Maybe if I finish that talk on the philosophy of performance tuning, they’ll let me do it?
