I’m still here, honest May 18, 2010

In the last 24 hours I’ve had four emails asking if I am OK – Apparently I am not blogging or bothering people via email! Well, I am OK (and thanks guys for the concern), I was just knackered.

Rule 1 of blogging “no one cares about you as an individual” (and, I am glad to say, that is a myth. Even in the zero-physical-contact medium of electronic communication, some have been concerned about my silence. Humanity may yet have a future)

Truth is, I damaged myself trying to get healthier {so it is back to the eating pies and drinking beer for me!*} and that caused lack of sleep and more unhealth and I ended up very, very, very tired and I was reduced to putting all my energy into doing the day job.

This has nothing to do with a Blog on technology and database, of course.

Ahh, but Yes, it does, it actually has a hell of a lot to do with it. I have been tired, hard-pressed and under-performing. So I concentrated on doing my primary job and nothing else. So I have not blogged and I have not emailed people and I have not generally helped as much as I would like.

The thing is, if you think of your comrades and fellow staff (and, for some of you, the people who work for you) most people around you could well be the same. The primary directive of business, at present, is to get everything for your current task out of the staff right now. That is the prime directive, push the staff hard to get x, y and z done. Or, for those of you working under an Agile Methodology, the handful of tasks in front of you for this sprint {or whatever the hell terminology is for your take on the “Get It Done NOW” methodology}.

I have had no bandwidth to do more than my day job of late. And I stopped helping. I think some current working practices and philosophies have the same, chronic effect.

Is this a good thing? I will let you decide.

For myself, I’ve had a week walking in Snowdonia (and I was not fit enough to get the best out of the time, but mentally it was a God-send). I thought nothing about technology; I thought very little at all. I walked up hills, I drank beer and wine and I ate lots of pies. And I now feel good.

I know I am doing better work now than I was 2 weeks ago.

So, I hope to start doing proper technical blogs again in the next week or so. But right now, having had a week of total down-time, I am ready and need to do my day job again. And they pay me, so I better go off and do it! Expect a proper technical blog next week.

{* I joke about damaging myself getting fitter, but I feel condemned to point out that being generally fitter and healthier is a good thing, even if you hurt yourself getting there. It is better to be old and fit than old and decrepit. Or old and dead. :-) I’m full of happy thoughts like that…}

Welcome to the Wider Layout April 2, 2010

Noticed anything new about my blog? It seems to have been eating pies and grown wider, somewhat like it’s author.

I’d really appreciate any feedback on if this new width is acceptable or is too large for how you browse the internet. I know it will be too wide for netbook users (of which I am one) without scaling the screen to 75%, but I seriously needed more space.

I very much liked the look of my blog when I set it up and I’ve been very happy with the service WordPress supplies for free for my blog. Their technical support have even answered a couple of questions I have thrown their way over the last 10 months or so {I get better free support off WordPress than I have had from software I’ve paid for}. But the narrow window for the text of my blog has been annoying me since the second or third week after I started. As for code and Explain Plan layout, boy that has been a pain. The use of “sourcode” was an early and much appreciated find and this formatting tool has been improved several times, even in the last 12 months. In fact, that earlier post I just linked to does not fully make sense now as one failed attempt to use the “sourcode” layout now works.

But the width limitation of the style sheet I chose forces me to spend a long time trying to edit code and especially Explain Plan outputs such that it lays out in a readable format. It makes doing technical blogs even more time-consuming.

It all came to a head a month ago when I started using screen shots in my blog. They are rendered down to an illegible 460 pixels wide. This was a real blow as, along with the other threads I want to blog about, I want to do some stuff on AWR in OEM and that can only be done with screenshots.

As you can see, this width issue is no longer such a problem for me. WordPress let you alter the CSS of your style sheet for a fee. But WordPress being the nice chaps they are, you can try it out for free first, to ensure you can do what you want to do. So I got a friend who understands all this web/CSS/html stuff to help me and within a couple of hours we had it sorted. The final step was to give 15 dollars a year to WordPress {I see it as buying them a couple of pints} and I can now bring to you the Wider Widlake Ramblings.

If you are curious as to how this change in width aids layout, see this post I have edited to show before and after layouts.

Screenshots are still going to be an issue, I can’t go beyond 800 pixels for the text window as with the side-bar, window margins, scroll bar etc, the blog would become wider than 1200 pixels (and I decided that 1200 pixels was as far as I could go without it becoming a major problem for some people to read my blog). But code layout is now fine and I can manage screenshots if I am careful.

It pains me to say this, but bigger is sometimes better.

New Year, same old rambling thoughts January 5, 2010

It’s not Friday but, heck, it’s a New Year, there are many of us who might appreciate a non-techie, pointless ramble at the start of the first full working week of a new decade…A Friday Philospohy for the New Year. {If anyone wants to point out the New Decade starts on 1st Jan 2011, go take a running jump – popular opinion is against you, even if logic is for you}.

I found the UKOUG techie conference this year particularly interesting as it was the first major meeting I have been to since I started blogging, and I came across two main opinions about my attempts:

Those who like my blog as it is “chatty” and rambles a bit.
Those who dislike it – because it is “chatty” and rambles a bit…
{oh, and the third opinion, the most common, of utter ignorance of my blog – there goes the ego}.

Well, you can’t please everyone. I was a little saddened, however, as I spoke to a couple of people I really admire in the Oracle Knowledge world and they landed on the “chatty and rambling – bad” side of things. Damn. But they are so good at what they do, I forgive them. The swines.

But then I remembered what I said to a fellow blogger the other month. We bloggers/twitterers all put forward what we blog about in our own style. We might not blog something that is new, we might blog something that is “well known”, but we put it in our own style. Some like it, some do not. It matters not, so long as it adds to the sum of decent knowledge out there.
Some will hate our style and not read, some will read and enjoy. So long as the information gets out there to more people, that is fine.

So, do I think everything I blog is decent knowledge? Oh, I wish. I like to think it is mostly there {and I wish it was all correct} but I am realistic. I test most of what I blog, or I have lived for real most of what I blog, but I will make mistakes. And sometimes I will hit the edge of something good and I put it up there in the hope others will contribute {like the recent one one translating min-max column values into human readable stuff}. And often people do contribute and that is really, really good.

But I do and will continue to make mistakes, be daft, or just put things poorly. I have learned a fair bit in the last 8 months about written communication, the art of communicating to a global audience and also about how not to spread a topic over several weeks as you hope you can “just finish of those half-written blogs in an hour or two” and find it takes weeks. If anyone wants to give me any constructive criticism, please do, but maybe use my email (mwidlake@btinternet.com) rather than flame my postings.

And my last rambling thought for the start of 2010? I am probably going to post less in the next 6 months. I am always sad when the blog by someone I enjoy goes very quiet, but then we all have real jobs to do, so I try to be patient. In my own case, I have noticed I now read a lot less of other people’s blogs as writing my own takes so long. And I am missing too much. There are blogs I really admire or I have discovered in the last 6 months (sometimes both) that I simply fail to really read and they know stuff. So I need to read them. I am going to try and maintain a steady 2-3 blog entries a week, but for the next 6 months I am going to concentrate on learning. Something blogging has taught me is I am really quite ignorant :-)

Good wishes for 2010 to all and everyone who stumbles across my ramblings.

When do We Learn #2 October 20, 2009

I exchanged a couple of mails with a friend a few weeks back about how the same topic can arise in a couple of blogs at the same time. Well, I had just blogged myself on when we learn and, blow me over with a feather, that Jonathan Lewis goes and post in a similar vein. He must be nicking ideas off my blog :-) {and yes, I am being tongue-in-cheek here}. We both post thought about needing spare capacity in your life to be able to spend the time to really understand how something works. Yes you learn a lot in the heat of a crisis, but you rarely reallu understand the details, ie become an expert, without having time to digest and qualify that knowledge.

I did write a long comment on his posting, including some links back to my own meandering thoughts on the topic, then realised that I would come across as a bit “me too” so I trimmed it and took out the links. But that is part of why I do my own blog, I found I was spamming other people’s pages with my diatribes and so decide to spam my own. {And I know I am meandering, I’m a bit sleep-deprived, stream of consciousness at the moment}. So here I can refer back to my own stuff and say “me too”, but you are already here reading this, so you only have yourself to blame :-)… Anyway, I wanted to refer back to a very early blog of mine about how much knowledge is enough. I try and make the point that you do not need to know everything, you can become a small-field or local expert just by being willing to learn a bit more.

Jonathan raises the point that he does not have a full time commitment to one client and so he has the luxury to investigate the details and oddities of what he looks into. He suggest this is a large part of why he is an expert, which I feel is true, and I am very happy to see one of the Oracle Names acknowledging that relative freedom from other pressures is key to having the luxury to chase down the details. Those of us in a full time role doing eg DBA, development or design work, have more than enough on our workday plates to keep us too busy. We cannot be top experts, we have a boss to satisfy and a role to fulfill. {Jonathan does not mention that chosing a career where you have luxury of time is also a pretty brave choice – you stand a good chance of earning a lot, lot less whilst working very hard to establish enough of a reputation to be able to earn enough to feed yourself and the cat}.

But this is not a black and white situatuation. There is room for many of us to become experts in our domain or in our locality. Our breadth of knowledge may never be as wide as others, we may not know more than anyone else in a given area {and let’s face, logically there can only be one person who knows the most about a given topic, and that one person is probably in denial about their superiority, which seems to be a defining quality of an expert – it is not so much humility I think as an acknowledgement of there being more to know and a desire to know it}. However, most of us can become the person in our organisation who knows most about X, or who can tie A, B and C together in a more holistic way than others (and that can be a real trick you know). There are always the top experts that you can call on for the worst problems, but you could become the person people come to first.

My advice would be to not try and learn everything about all aspects of Oracle, because you can’t, but rather learn a lot about one or two areas {and consider areas that are more unusual, not just “tuning SQL” or “the CBO”} and expand just your general knowledge of the wider field. And never forget that there is more to learn. So long as you are taking in more knowledge and understanding, you are improving. The best way to do it? Don’t just read other people’s stuff, try teaching someone else. It never ceases to amaze me how stupid I realise I am when I try and show someone else how something works. But that’s OK, so long as they learn it’s fine. If I learn as well, it’s great, and I nearly always do.

I’m getting on a bit, I think I am finally getting the hang of the idea that the more you know the more you realise you don’t know, I wish I knew that when I knew nothing.

Friday Philosophy -Do I think Oracle is Rubbish? October 8, 2009

1 comment so far

This should be a “Friday Philosophy” posting really, but heck it’s my blog, I can do what I want {quiet smile}. Besides, by the time I finish this, it might well BE Friday. Oh, heck, I’ll just change the title now to a Friday Philosophy one…

I’ve been reviewing some of my blog this week {it is coming up to 6 months since I started so I was looking back at how it has gone}. Something struck me, which is I can be pretty negative about Oracle software and even Oracle Corp at times.

I mostly seem to pick up on oddities, things that do not work as first seems, even outright bugs. I do not often post about “this is how this cool Oracle feature works” or “I used this part of Oracle to solve this problem”. Partly the reason is that there are a lot of blogs and web pages about “how this feature works”, so the need is generally already met. Partly it is that I, like most people, are more interested in exceptions, gotchas and things going wrong. If it works, heck you just need to read the manual don’t you?

So, do I like Oracle?

Yes. Over all I really like working with Oracle. This is because:

  • I can store and work with pretty much whatever data I have ever needed to with Oracle. It is rare for me to be utterly stumped how to achieve something, though it could take time and maybe be a tad slow or a little inelegant, but it can be done.
  • Despite my recent complaints, you can chuck a hell of a lot of data at Oracle. Back in 2002 I was asked if I could put 7 or 8 Terabytes of data into an Oracle database. I did not even pause before saying “Yes!” – though I knew it would be a big job to do so in a way that was maintainable. I’d now feel the same about a couple of hundred TB.
  • The core technology works really well. We all complain about bits and pieces admitedly, but if I have a complex SQL statement with 15 tables and 25 where clauses, I don’t worry about the database giving me the wrong answer, I worry about the developer having written it wrongly {or Oracle running it slowly, but that keeps me in work, hehe.}. I can back up Oracle in many ways and, once I have proven my recovery, I know I can rely on the backup continuing to work, at least from an Oracle perspective. I’ve never yet lost any production data. Do I worry about transactional consistency? Never. Maybe I should, I’ve seen a couple of blogs showing how it can happen, but in my real-work life, I never even think about it.
  • Oracle does continue to improve the core products and they will listen to the community. It might not seem like it at times, I know, but they do. It can just take a long time for things to come through. As an example, I worked with the Oracle InterMedia developers back with the Oracle 10 beta program in 2003. They {well, to be specific, a very clever lady Melli Annamalia} were adding stuff back then that we and others needed that did not get to see the light of day in 10GR1, but was there as  a load of PL/SQL to do it in 10GR2. Melli said she was adding it into the code base as ‘C’ as well but it would take a while. It did, I think it was part of the 11G release.

Will this stop me complaining and whining on about bits of Oracle I don’t like or that do not work as they should? Absolutely not. As Piet de Visser said on a comment to one of my recent blogs, it is beholden on us Users to keep Oracle Corp honest. But I thought I ought to mention, at least once, that I do actually like Oracle.

I Like Oracle, OK?

Grudgingly :-)

Friday Philosophy – Who Comes Looking? September 18, 2009

I’ve been running this blog for a few months now and I find it interesting to see how people come to it. A handful of people come to it as I tell them I have a blog page, but most people come across it by either:

  • Links from other blogs or web pages.
  • Search engines.

WordPress gives me stats on these for Today and Yesterday and I can check back on the referrers and searches for any given day, going back several months. Most blog sites provide the same features, I thought I would just run through them for those who do not have a blog.

I can tell when I have been mentioned on someone else’s blog, as I usually see a spike in my hits and their web page is at or near the top of the list of referrers. Interestingly, I will sometimes see a burst of hits from an old reference on someone else’s blog or webpage. I think this happens when a third person has referenced the page or person which then referenced me.

Another interesting facet is the impact on my hits if an Oracle Name mentions me. My busiest day occurred when Richard Foote mentioned a posting I did on “Unhelpful Helpful People” and a couple of other well-known Oracle Names also picked up on the thread. It’s a bit like a small-time-actor getting into a scene with a Hollywood Star :-).

The most interesting, though, are the search engine hits.

My favorite search term to lead to my blog so far is “martin widlake unhelpful people”. I really hope that was someone looking for the post I mention above, as opposed to anything else…

As time goes by, the search engine hits are generating a larger and larger slice of my traffic (and the personal mentions less and less :-) ). This is going to be partly due to me putting more content on the Blog to be found but also, as I get more hits and links, search engines will give me more prominence. It becomes self-feeding. Search engines find me as I have been visited before, so I get visited again and Search engines see that I have been visited even more and move me up the list…

{This is, of course, how Burleson gets so much traffic, he always references back to himself and his web sites and appears to have several sites that all cross-reference between them, priming the search engine pump (or absolutely flooding it, I suspect)}.

Some of the most common searches that find me are on obscure items I have blogged about. They may not be of such general interest {such as when I blogged about errors with gathering system statistics {{and more to follow on that topic}} } but I guess when someone hits the same issue or topic, I am one of a very few places that has mentioned it. I get a steady trickle of hits for “c_obj#_intcol#” since I blogged about it often being the biggest object in the SYSTEM tablespace. So perhaps to increase my search engine hits I should not blog about mainstream issues but rather really obscure, odd stuff than almost no one is interested in!

Some days I will get several hits by people searching on “Martin Widlake”. I wonder why they are searching on me specifically. Occasionally, it has been just before I am called about a job. Usually not though {so maybe it was about a job - but then they found my blog and decided against it…}.

Some searches that get to my blog are just odd. Yesterday one search that found me was “how to put fingers on keyboard”. Why? I have no idea why a search on that would land on my blog. Maybe I should try it!

Oh, and I suddenly have a favorite search that found me, hot in today, just as I am blogging about the very topic:

“it’s a crock of cr4p and it stinks”

Now what is that about? Why search on it and why find me?

*sigh*

Spending Time in London August 4, 2009

Posted by mwidlake in Blogging, Perceptions.

I’m currently working in London, to the west of the centre but within coverage of the underground system. As a result, getting to and from home and work takes a looong time. This gives me a little time to do stuff on my netbook on the train, but if it is really busy and when I am on the tube it is not possible to do this. It’s wasted time.

To keep as much of my sanity intact as I can and reduce the amount of time I spend doing nothing but wondering why all other commuters appear so unfriendly {I know, most of them are thinking exactly the same :-)}, I opt to stay in London a couple of nights a week. The benefit of this is that either I have nothing to do in the evening and I can read manuals and do this blog {or alternatively watch rubbish on TV or read a book}. Or I can go and drink beer with people I know. I don’t know that many people in London, I have to confess, but I have had a couple of very enjoyable evenings so far.

Tonight was with Doug Burns. I don’t know Doug that well, but have enjoyed talking to him at UKOUG meetings and exchanging emails/comments on blogs. It was excellent to spend a couple of hours and maybe one too many beers with Doug and talk about what can only be described as an eclectic range of topics. I also managed to mug him for his excellent presentation on AWR for the next MI SIG meeting in October. I hope that last beer was not too much and he remembers…

This is part of the whole Oracle Community thing. It’s good to Blog, it’s good to go on forums and it is good to exchange emails, but you can’t beat meeting in person, either at conference, at user group meetings or just because you are in the same town that evening. I find once you have met, communicating is a lot easier {I had an excellent night in Newcastle with Piet de Visser about 18 months ago and now we exchange rants and thoughts quite often}. So, if anyone out there is in London and fancies a beer, you could drop me a line. I’ll buy the first one if you ask nicely.

Right, where was that manual on oracle wait interface…Oh, “Celebrity animals have got talent on ice” has come on the TV, maybe I’ll watch that.

How Much Knowledge is Enough? June 13, 2009

Posted by mwidlake in Blogging, Perceptions, performance.
Tags: , ,

I’ve had a bee in my bonnet for a good few years now, which is this:

How do you learn enough about something new to be useful when you are working 40, 50, 60 hours a week?

Another bee is how much do you actually need to know to become useful? The bee following that one is if you do not have enough time to investigate something, how do you find the answer? Buzzing up behind is to fully understand how something works, you often need a staggering amount of back knowledge - how do you get it? Oh dear, it’s a hive in my head, not a single bee.

I am of course in this blog mostly thinking about Oracle and in particular Oracle performance. I think that these days it must be really very hard to get going with performance tuning as it has become such a broad topic. I don’t know if you have noticed but nearly all the performance experts are not in their teens. Or twenties. And precious few in their thirties. Forties are pretty much the norm.  We {and please excuse my audacity in putting myself in such an august group}  have been doing Oracle and performance for many years and have stacked up knowledge and understanding to help us.

For me this issue was thrown into sharp relief about 4 or 5 years ago. I had become a manager and, although I was learning lots of other skills and things, when it came to Oracle Technology I think I was forgetting more than I was learning. Oh, I was learning some new Oracle stuff but it was at a more infrastructure level. The real kick of reality was going to presentations on performance and Oracle internals. At the end of the 90′s I would go along and learn one or two new things but knew 90% of what was said. By the mid 2000′s I would go along and know 50% , the other 50% would be new. Then I went to one talk and found I was scribbling away as I knew precious little of what was being presented. More worryingly, I was struggling with “How does this fit in with what I already know?”.  I just didn’t know enough of the modern stuff.

That was a pivotal moment for me. It had the immediate effect of making me start reading blogs and books and manuals again. It’s not easy to find the time but I soon noticed the benefit. Even if I learnt only a little more one evening a week, I would invariably find that knowledge helping me the very next week or month. I was back on the road to being an expert. {Or so I thought}. Oh, it had a long term effect too. I changed job and went back to the technical, but that is for another day.

But hang on, during my decline I had not stopped being useful. I was still the Oracle performance expert where I worked and could still solve most of the performance issues I came across. It made me realise you do not need to know everything to be useful and you could solve a lot of problems without knowing every little detail of how something works. A good general knowledge of the Oracle environment and a logical approach to problem solving goes a long way.

I actually started to get annoyed by the “attitude” of experts who would bang on and on and on about how you should test everything and prove to yourself that your fix to a problem had fixed itas otherwise it was just being hopeful. I thought to myself “That is fine for you, oh exalted expert, as you have time for all this and don’t have 60 hours of day job to do every week. Give us a break and get real. Most of us have to get the problem solved, move on and get by with imperfect knowledge. Doing all that testing and proving, although nice in a perfect world, is not going to happen”.

Yep, I had an attitude problem :-). I was getting angry at what I now think is just a difference in perception. I’ll come back to that in a moment.

I don’t think I am going to go back on my opinion that for most people in a normal job, there simply is not time to do all the testing and proving and you have to move on, Making do with received knowledge. It just is not an ideal world. However, we need the experts to uncover that knowledge and we need experts who are willing to communicate that knowledge and we need experts we can rely on. I am very, very grateful to the experts I have learned from.  

All the time on blogs, forums and conversations the issue of “how do we know what sources we can trust” regularly comes up. Well, unfortunately I think that if you do not have time to do the testing and learning needed to become an expert yourself, you have to simple chose your experts, accept what they say but remain slightly skeptical about what they say. Everyone makes mistakes after all. I would advise you only accept someone as an expert and rely on their advice if they are willing to demonstrate why they believe what they believe. Everything else is just an unsubstantiated opinion. 

But I’ve come to some conclusions about most of the above questions I started with.

  1. If you are judicious in choosing your sources, you can learn more reliably and easily.
  2. Even a little bit of more knowledge helps and it often comes into use very quickly.
  3. The hard part? You have to make that time to learn, sorry.
  4. Although testing and proving is good, life is not perfect. If you did (1) you might get away without it. But don’t blame the expert if you get caught out.

But I’ve not addressed the point about needing all that back knowledge to fully understand how something works. Well, I think there is no short cut on that one. If you want to be an expert you need that background. And you need to be sure about that background. And that is where it all has fallen apart for me. I started a blog!

I already knew you learn a lot by teaching others, I’ve been running training courses on and off for a few years. But in writing a blog that is open to the whole community, I’ve realised I know less than I thought. A lot less. And if I want to be a source of knowledge, an expert, I have to fill a lot of those gaps. So I am going to have to read a lot, test things, makes sure that when I believe I know something I’ve checked into it and, when I fix something, I know why it is fixed {as best I can, that is} . All those things experts tell us we need to do. And that brings me back to my perception issue. 

Those who I think of as the best in this field all pretty much give the advice to test and prove. And they have to do this themselves all the time, to make sure what they say is right. And they are the best as what they say is nearly always right. It seems to be excellent advice.

However, I think it is only good advice, as it is advice you can’t always take, because there is too much else to do. I think sometimes experts forget that many people are just too pressured at work to do their own testing, not because they don’t want to test but because you can only live so long without sleeping. 

Anyway, I said something foolish about becoming an expert. I better go and check out some other blogs… start reading some manuals… try out a few ideas on my test database.  I’ll get back to you on how I’m progressing on that one in about, say, a year or two? All those gaps to fill….

Blogtastic June 7, 2009

I wonder how many blog entries world-wide have the title “blogtastic” or “blogging about blogs” or something similar.

I’ve been blogging properly for about 3 weeks now. Why did I start? 3 main reasons.

  • I forget stuff {I’m getting to that age} so I thought a blog was as good a place as any to stick stuff where I could find it.
  • I like to teach.  I know, it sounds a bit naff, but I honestly like explaining things and teching people stuff. If I was starting out on my career again, I would do more training.
  • Narcisism. There has to be an element of wanting to be noticed in anyone who blogs! I’d like to be a “C” list Oracle Name :-)

After a few weeks blogging, what have I learned?

  • I really like it when I get comments. It is less like talking to an empty room.
  • I am talking to an empty room! When I linked back to my blog from Jonathan Lewis’s blog my hits jumped from a half dozen to 80. They are heading back to a half dozen now.
  • Google does not pick up stuff just because it is on a blog. Which is maybe good as think how many spurious hits you would get for 99% of stuff and it is bad as, not only are people missing out on the great stuff I say, more worryinlgy, when I ask Google about some aspect of Oracle I know nothing about, how much great stuff am I missing?
  • It takes a lot of time to do rigorous explanations of oracle facts, which is what I have always demanded from my Oracle sources (and is why I use “-burleson” in my google searches).

I know my blogs are too long, I’ve been told. But then, they are supposed to be for my own benefit and I like to see why I decided what I think I know.

It takes a loooong time to say what you want to say. I’ve put a few basic techie things up and have not touched on my 2 other areas, VLDB and management. It is going to take me a long time to put down things I want to put down. I have a list of , ohhh, maybe 50 things to blog about already.

And last for now? It’s addictive. I want to put down everything now.I want people to find and read my blog now. I want my stats to be high.Why? Narcisism of course :-) But also because if I’m going to teach people there has to be people listening.

And really for last. Why do I want to teach? Well, the post on Consistent Gets says it all. When you teach people, you learn. The hardest questions often come from people who know the least about a topic.

Well, I pinged an email to the nice support guys at WordPress.com about whether I had missed something about turning off the gutter (line numbering) from the sourcode view, but there is no flag I missed and no mention was made of it coming in the future. I also am a little concerned that using sourcecode slows down the rendering of the web page. So I might save it for special code.

I also found out that if your code sample is more than about 60 characters long, you exceed the width of the text area and get scroll bars to the bottom and side (not of course helped by not being able to suppres the line numbering):

select count(*) "Invalid count:" from dba_objects where status != 'VALID';
select substr(owner,1,14) ownr
,substr(object_name||' - '|| object_type,1,36) obj_name
,to_char(created,'DD-MON-YY') CREATED
,to_char(last_ddl_time,'ddmmyy hh24:mi') last_ddl
from dba_objects where status !='VALID'
order by 1,2
/

compared to:

select count(*) "Invalid count:"
from dba_objects where status != 'VALID';
select substr(owner,1,14) ownr
,substr(object_name||' - '|| object_type,1,36) obj_name
,to_char(created,'DD-MON-YY') CREATED
,to_char(last_ddl_time,'ddmmyy hh24:mi') last_ddl
from dba_objects where status !='VALID'
order by 1,2
/

But the nice support desk person did suggest I try pre tags;

select count(*) "Invalid count:"
from dba_objects where status != 'VALID';
select substr(owner,1,14) ownr
,substr(object_name||' - '|| object_type,1,36) obj_name
,to_char(created,'DD-MON-YY') CREATED
,to_char(last_ddl_time,'ddmmyy hh24:mi') last_ddl
from dba_objects where status !='VALID'
order by 1,2
/

Hmmm, nope, not really better than code.
I am starting to think I duffed slightly in chosing this style, Regulus. I suspect it does not respond to many formatting tags.

On the plus side, the nice helpdesk person did agree to putting the issue of access to the flags for sourcecode on the list of requested enhancements. Nice people.
