So you wanna be a good sysadmin? I don’t blame you. It’s fun, and it’s lucrative. Especially if you do it right. The difference between a good admin and a bad one are many and varied. Most importantly, it boils down to a level of devotion to the company. And a knowledge that is expansive. Not that it has to be all-encompassing. One of the important things to know is the limit of your knowledge. Know your comfort zones, and know your limits. ...
I’ve been writing Java in one sense or another for a few years now. I learnt stuff at university, then used it in a few jobs. I’ve written Beans and Applets, and various bits of stuff in between. It’s fairly safe to say, that I like Java. One thing however, that’s been a pretty consistent bugbear in all the time I’ve been writing Java, has been the classpath, and dependency resolution. Luckily, all that can now change. ...
Right. This is important. I want you stop what you’re doing and read this. It won’t take long. I’ve just witnessed another act of homophobic bullying amongst school children. Sadly this time, they weren’t in uniform, so tracking down the school responsible is going to be somewhat harder. What I can tell you is that there were 4 boys, three black, one white, and all very troubling. The thing that troubles me most, as gay man living in london, is that if these kids are to be believed, then we are all under threat. ...
So there’s this saying, “There’s nothing more dangerous than a bored engineer”; I tend to think that it’s true. I’ve had very little to do at work lately, which has been in equal parts frustrating and annoying. I like having stuff to do. I like having plans for the future, but at the moment, there’s very little. Anyway. I popped into Westfield the other day, and caught a Free BBC Prom. Very cool. Then I had a poke around on my mobile and realised two things. ...
It has recently been brought to my attention that a number of users of cloud-based hosting services tend to use an “integrated” backup solution provided by the cloud host. This is probably some form of snapshot-based backup of a server’s state. I quite like the idea of doing this, especially if there’s no impact to the server being backed up whilst the snapshot is taken. However, I can immediately see one big problem with it. ...
Personally, I hate the idea of using a desktop as a server in a production environment. I’m going to define the term “production environment” first. If you’ve got an environment, any environment where the service provided is relied on by anybody, for any reason, then that’s a production environment. If it’s just for you, and you don’t mind when it all goes wrong and the shit hits the fan, then that’s fine. ...
This is a little ranty, but it’s really pissed me off lately. That’s right. It’s you. The ones with image hotlink protection, and the ones who rewrite URLs to do strange and special SEO things, but who don’t actually think about what happens when you send someone a link to something. (For the uninformed, hotlink protection is that thing where you get sent a link to an image, but the site owner is being draconian, and redirects you to google, because your referer wasn’t their own site, so the image must have been stolen, and put on another webpage (!)) ...
Sometimes you read something on the internet and think “Huh? Really?”. When I read this, I swear, you could almost hear my brain go boggle. When I first started using Java, I remember reading something in the EULA (yes, I read it), about not using it for mission-critical or life-critical circumstances. Something about avionics and nuclear power stations. Specifically “You acknowledge that Licensed Software is not designed or intended for use in the design, construction, operation or maintenance of any nuclear facility.” ...
(If you’ve just read this for the first time today, you should read all of it.) The first meme we’ll discuss is the “Royal Wedding Name”. BOHICA. Again, It seems that some of you aren’t understanding how these things work. The Royal Wedding Name asks for Your grandparent’s name (first name, male or female) Your first pet’s name The name of the street you grew up on. Right, you lot. Stop this now. ...
When I was growing up, one of the things that particularly interested me about the English language were idioms and proverbs. I think today, whilst many are still suffering the effects of the week, we should look a little more closely at one particular proverb, and perhaps its effective meaning today. “Don’t put all your eggs in one basket” :- This phrase is commonly (and some might say, incorrectly) attributed to Miguel Cervantes (in Don Quixote), but some sources have reported its usage as early as 1600. Also of little surprise is that many other historical cultures had similar phrases. ...
