Camera Joys… and Windows Woes

nikond600In January 2014, I turn 50. Rather more significantly, in November 2013, Benjamin Britten would have turned 100, if he hadn’t been unlucky enough to die in 1976. But whatever: the end of this year, one way or another, turns out to be of great personal significance… and, as a result, me and ToH will be travelling back to the UK in late November, to celebrate both occasions with family, friends and any strangers that want to take pity on a couple of wandering Aussies.

Yes, we are both completely bonkers, and fully understand that we are facing average maximum day-time temperatures of around 8 degrees Celsius (46 Fahrenheit for old-timers and American readers). But we will be in Aldeburgh on November 22nd, standing in the graveyard and paying respects to one of the great composers of our time. So it’s worth it.

I have also wangled a lifetime-desired trip to Bletchley Park (where we won the war by decrypting German Enigma traffic, happening also to invent computers along the way, just in passing). I’m looking forward to that a lot.

The trip comes with some costs attached, however (and I’m not talking about the unheard-of amounts that Aldeburgh’s White Lion hotel wants to charge us!). Specifically, ToH says that a new camera is needed since the last lot of London photos were a tad disappointing, and thus last Thursday we shelled out around $3000 for the Nikon D600 you see above. I coughed a bit, but since I’ve only just recently splashed out $2000 for a new Toshiba laptop, it’s difficult to complain much!

In fact, of course, there is no need to complain at all, because ToH’s former Nikon D80 gets handed down to me (definitely the ugly step-sister when it comes to matters photographical), and I accordingly take a rather large step up from the little Lumix DWC-FH20 I’ve been using for the past 4 years. The last time I used an SLR, digital or analogue, was back in the 1980s, when my trusty (built like a Soviet tank, in fact) Zenit did me duty in the likes of Bulgaria, Zimbabwe and Botswana… so it’s going to be a learning curve for me.

Of course, this means having to deal with RAW images and learning to stitch and crop them as the mood takes me -and thus I feel compelled to renew my hitherto fleeting acquaintance with Photoshop. And Photoshop, of course, means Windows (for Wine will let Photoshop 3 just about pass muster, but cannot cope with Photoshop 5, which we use chez Dizwell). And thus it is that only a fortnight after having purged the house of the last non-ToH-owned Windows machine, I have felt compelled to dump Fedora from my desktop and reverted to Windows 8. After 6 months uninterrupted Linux loveliness, I somewhat regret the move, but no way, no how am I going to try to wrestle GIMP into submission!

I hasten to add that it is not all ToH’s fault, since work is asking me to pick up some SQL Server administration duties, thus making domestic installation of Server 2012 and SQL Server 2012 look like a sensible proposition for career prospects. Time to wipe CentOS off my two HP Proliant Microtower servers, then, after 9 happy months of just sitting there and working beautifully…

Some updates about Windows 8, Windows 2012, Hyper-V and SQL Server to come, too!

All Change!

changeRegular vistors, if there be such, will notice quite a few changes to the neighbourhood!

I’ve decided to go ‘static front page’ and try and organise the site content a bit better.

It’s mainly a reaction to pumping hundred thousand-line articles into Blog format thanks to Salisbury: hopefully, the new site structure will mean the blog can be a blog (and who knows: I might actually put more bloggy stuff into it?!) and the technical stuff can be clearly differentiated from it.

Until it’s all sorted, stuff might be tricky to find and the site seem otherwise incomprehensible. Please bear with me.

So true…

I couldn’t help but nod vigorously as I read this story: http://www.theregister.co.uk/2013/02/07/home_lab_career_saver/

In case that ever disappears, here are the salient bits:

IT professionals can’t assume their employers want, or can afford to, train them in the latest technologies and should hone and acquire new skills at home in a self-built test lab. That’s the opinion of Mike Laverick, VMware’s senior cloud infrastructure evangelist.

“The days of being sent on training courses is gone,” he told the user groups. “The burden is now on you to get the skills and knowledge you need. It is assumed you will learn as you go.”

“I drove my career development by not waiting for my employer to say this is an interesting technology. I told my employer I have used this in my home lab and this is what it can do.”

My new PC (see last blog) was a nod in this direction (though taken long before that article appeared). With some solid state hard disks of sufficient capacity, an 8-thread CPU, 32Gigs of RAM and some virtualization software, there’s not a lot you can’t simulate for a thousand dollars or so at home. (I have been coping with 3 other PCs, 4 laptops and a Xeon server before the latest acquisition, but the new PC makes a lot of that redundant).

toshiba-p870Similar thinking has just lead me to buy a ‘mobile home lab’, in the form of one of these. It wasn’t cheap ($1900), but 1.5TB of hard disk (spinning variety) and 16GB RAM means I can simulate the key things I need (RAC, DataGuard, Oracle/SQL Server integration, Active Directory authentication of Oracle users and so on) on the train.

Those comments about knowing what interesting technology can do, without having to wait for formal training to find out, are key, I think. I used to get asked a lot what it took to become a good DBA… and one of the key ingredients, in my view, was the willingness and the ability to experiment with the technology at home. The magic ingredient for that was virtualization above all -and it’s funny that it’s now a VMware man humming the same sort of tune. Virtualization plus a decent bit of hardware (without going overboard!) means that’s truly possible in a way it wasn’t always when I was first banging on about it back in 2000.

I particularly liked Mike’s comments about “the Girlfriend impact” of a home lab, though: ToH can attest to the accuracy of his description of the way this metric waxes and wanes, depending on how many cables, screwdrivers, mice, keyboards, RAM sticks and hard drives are left scattered around the dining room, against how much money is spent on new kit that renders that sort of tinkering redundant! I reckon we’ll have to have won the world’s biggest lottery draw before ToH nods through an £870-per-month server hosting arrangement, though! Obviously Mike is blessed with more technologically-understanding other halves than some of us!!

Happy Christmas

Things have been pretty hectic since I got back from England, and as a result, promised articles have not materialized. I have a couple of weeks now in which I can at least hope to rectify that a little.

The Christmas elves have allowed me to purchase a new i7-3770, 32GB RAM, 512GB Solid State HDD, 2TB HDD PC, although they weren’t quite organised enough to make sure it turned up before the Big Day itself. Hopefully it will arrive sometime early in the new year and I can set-to building a desktop 2-node RAC with active clustered data guard, which should be fun.

Otherwise, I shall probably be mostly off-air over the break, so I’d like take this opportunity to wish all my readers a very peaceful and happy Christmas and New Year.

Normal Service has been resumed…

The move between UK-based and AU-based hosts took a bit longer than I expected, mainly because I had to keep checking that no files had been left behind by the various backup tools I was using. Something always seemed to slip through the net! I also ended up having to re-install all my WordPress Plugins, because the included backup mechanism doesn’t bring those across for you automatically. Unfortunately, I use a lot of plugins!

But anyway: it’s all done now, hopefully not to happen again for a long time. Fingers crossed! If you find anything not looking or working right, please let me know.

I can tell you in advance that my Kickstart Configurator doesn’t work, and I have yet to understand why. I believe it was broken on the original site, too, but no-one noticed… from which I deduce that this needn’t be high on my list of priorities! It’s got something to do with a WordPress custom form calling a php file: the custom form’s fine; the php file is there with all the right permissions… but for some reason, trying to call it simply produces a ‘file not found’ error. I’ll fix it as soon as I can, anyway.

I’ll also admit before it’s mentioned that the blog has reverted to its ‘dizwell’ name, and ‘diznix’ has been put out to pasture. No-one but me referred to it as ‘diznix’ anyway. If you bookmarked the diznix.com domain, that will continue to work, though.

On the Move

For a variety of reasons (but mostly because of cost and speed), I have found my current UK-based host to be inadequate. I am therefore moving the site back to Australian hosts. The usual DNS propagation issues can be expected to arise, so don’t be surprised if things go “on the blink” for a couple of days, at least: normal service will be resumed ASAP.

The transition should be finished in a few days.

Cosmetics

I‘ve made a couple of changes to this site’s CSS, so that it is now a bit wider than before (1200 pixels, if you were going to ask). The default font has also changed (to Segoe UI, so all Windows 7 -and upwards!- users should see it without effort). If that font’s not installed, you’ll see something else (Gill Sans, Georgia or the old font, in that order of precedence). Code snippets have also changed font, size and colour: hopefully they are more readable as a result.

Finally, if you click on a post or an article, at the bottom, there should be a ‘print friendly’ button visible, which lets you extricate the text from the particular format in which it’s displayed here. Unfortunately, that links through to an ad-sponsored third-party service, so (a) there’s no guarantee it will always work and (b) you may have to put up with some ads as you convert to plain text/PDF/whatever. It was either that, or hand-code some CSS of my own… and I have more pressing things right now than to hand-code CSS!

Feel free to let me know if the changes result in something you feel you cannot cope with!

Proved right!

I hate being right all the time.

I said a new job would probably mean I’d not be posting as frequently as before… and so it has proved :-(

I doubt the situation will get better any time soon, either: the new employer has an SOE that is locked down so tight it’s difficult to breathe at times. Amongst other things, this means no wordpress.com sites can be visited (so Jonathan Lewis is out… please get a proper, independent domain name for your blog, Jonathan, so I can visit once more!) and no sites that involve a login (including this one) are accessible.

Fair enough, actually. I approve of SOEs on the whole, and I can understand the particular reasons for this one to be as strict as it is… but it sure makes things inconvenient at times, too!

It hasn’t helped that I ditched Google and self-hosted all my email: my email servers cannot make it through the SOE cloaking shield, either, so I’ve effectively had 3 weeks without any personal email at all. Why not email at home, after work, I hear you cry? Er, well… yes: had I not made to foolhardy decision to try out new ISPs, I suppose that might have worked. As it is, living where I live, it turns out that I have a choice of one ISP that actually works, so I’ve ended back with the one I started with… but it’s been mayhem getting there.

Anyway, the long and the short of it is that I will update this blog with something whenever I can, but you really don’t want to be holding your breath in the meantime!

 

Change of Host – all OK

If you are reading this then, I think, we can safely assume that my recent change of host for this blog has been a success.

This site was previously hosted on WordPress.com (and the old content is still there at diznix.wordpress.com). Now I have exported the whole lot (comments, images, links… the works, with any luck) and imported them again to a self-managed host’s servers (somewhere in the UK, I believe).

Once the DNS changes propagate properly, things should settle down a bit and all should be well. Fingers crossed, anyway.

If you come across any broken links/image placeholders etc, by all means let me know about them and I’ll fix them as soon as I can.

Also, a final note of apology to the people who ‘followed’ me on the WordPress-hosted version of the site. I’ve no idea what ‘following’ does for you, or how you interact with it, but it’s a special feature of WordPress.com itself… so that particular bit of functionality has gone away and isn’t going to be coming back. I think if you want to be kept posted of new content here, you’ll just have to subscribe to the RSS feed. Happy to hear from anyone that’s seriously inconvenienced by this, to see if there’s anything that can be done to improve on that suggestion (though my hopes aren’t high).

Snakey Saved

Well, it was more of a close-run thing than I’d care to have happen again, but Marion turned up from the Wildlife Rescue Service and saved the day.

She began by being rather braver (and closer!) with a pair of wire cutters than I would have been:

That didn’t see to be doing the trick, though, and after several attempts on the part of the snake to bite her, Marion switched to the ‘get it from behind’ school of animal rescue:

I might mention in passing that Snakey decided to eject copious quantities of poo at this point, producing a unique smell that I shan’t forget in a hurry. Marion ended up wearing most of it, but we all ended up sharing its essential qualities!

Just before the final snip of the wire-cutters, this was Snakey:

I’d usually try to stroke any wildlife we get on the nose before it darts off, but on this occasion, I decided not to.

As he was finally snipped free, Snakey tried to bite Marion, his rescuer, and me, who happened to be passing (a bit too close) by. But she got him into a storage container easily enough, after which he calmed down. Marion (somewhat bravely in my view!) then popped him on her passenger seat and drove him away for a quiet spell in a veterinary clinic. All being well, she’ll return in a few days to let Snakey loose again, back where he belongs.

There’s never a dull moment around here, I can tell you!
