This post is a list of many of the reasons to use Postgres, much this content as well as how to use these features will later be curated within PostgresGuide.com . If you need to get started check out Postgres.app for Mac, or get a Cloud instance at Heroku Postgres for free UPDATE: A part 2 has been posted on Why Use Postgres Very often recently I find myself explaining why Postgres is so great. In an effort to save myself a....

I recently embarked upon a performance investigation to figure out why a particular operation was slow. My theory was that it was the serialization/deserialization cost with a set of large objects; my colleague’s theory was the iteration over the set. We were both wrong. The investigation became intriguing when we started measuring the elapsed time at various points in the application and noticed that the bulk of the time was being spent ..

My computer met with a large quantity of pepi max last night. Currently the only working computer I have is my work machine, well this isn’t strictly true, I also have a very damp one that won’t turn on. Aside from these ramblings and more to the point, this means that until I can save, order and build a new machine (and hopefully recover my data) I’m unable to continue work on the BBC News app. I know there is currently a minor bug aroun..

If you were following my blog, you may seem that I have once tried to make WS-FTP project with Java, however the web-sockets were on draft and it was changing quickly and they were not safe. Meantime, I have learned and mastered NodeJS and met Socket.io, and I decided to use them, since they were providing a better interface and it was much more easier to code a web server with NodeJS rather than Java.

One feature I miss from my Perl days, which I’ve never seen in another language. I am writing a test loop and I want it to run 10k times. So I write, in Java: for (int i = 0; i < 10000; i++) { ... } Nothing surprising about that. But in Perl I could write: for (my $i = 0; $i < 10_000; $i++) { ... } You can put underscores anywhere when writing number literals, and they will get ignored by Perl. So you can make such large numbers a lot..

Overview In this primer we’ll get a first taste of the mathematics that goes into the analysis of sound and images. In the next few primers, we’ll be building the foundation for a number of projects in this domain: extracting features of music for classification, constructing so-called hybrid images, and other image manipulations for machine vision problems (for instance, for use in neural networks or support vector machines; we’re planning..

The nostalgia of serial console servers, kvm’s and switched PDU’s is hopefully no longer visible in your server room. If not, you must definitely start playing catch up. Please forgive my ignorance, but these things might still be common for big windows shops, however if that’s the case, you’ve got an entirely different set of problems ;) IPMI is an IP based protocol that allows you to talk directly to a little computer, usually built in ..

So you’ve learned screen, ssh and vim. Time to take your skills to level two. Day one: You’ve logged in to your server remotely via ssh. You run “screen -xRR”, and two minutes later you’re busy chatting away in irssi and vim is running in the other window, because, you know, real sysadmins don’t use emacs. Lunch time: You grab your laptop and head off for lunch. When you open the lid and look at your terminals, they’re all frozen, becau..

I have recently switched jobs and had to set up a home office. I have heard a lot of good things about standing desks and thought this was the perfect opportunity to try one. I had looked for one online but those things aren’t cheap (~ $800). Instead of dropping some serious cash, I stacked up some bins and made a poorman’s standing desk. I have a laptop stand and a second monitor. Nothing special, really. I have been standing while....

On Friday my iPhone 4 took its dying breath and stopped receiving calls while rebooting itself repeatedly. For the record, this is what my iPhone 4 looks like. Its death is probably my fault. It’s seen two major falls - the first after being placed on top of thin air instead of the bathroom counter after a long night of DXHR and the second during a spider incident.

My contract with my previous shared hosting contractor is coming to a close, and as they seem to have all but abandoned their business, I decided it was time to move away. I looked at using Amazon’s EC2, but ultimately decided to go with Bhost, with which I’m fairly happy so far. To get some decent performance out of it, I planned to use Nginx as my web server Keep using Apache as usual All my websites are configured to work with apache, ....

There was a question in Oracle-L about where is the LOB data actually stored (in the row or the LOB segments) and what are the exact conditions when a switch from one to another may happen. The documentation isn’t fully clear about this and the “4000 bytes” number may mislead people to think that you can store 4000 bytes of your data in a LOB item before it must move out-of-line. I clarified this in my post in Oracle-L, but will pos..

The Complexity of Things Previously on this blog (quite a while ago), we’ve investigated some simple ideas of using randomness in artistic design (psychedelic art, and earlier randomized css designs). Here we intend to give a more thorough and rigorous introduction to the study of the complexity of strings. This naturally falls into the realm of computability theory and complexity theory, and so we refer the novice reader to our other prime..

A while ago I wrote this , which summarised my frustration with cookie cutter quests in MMORPGs. Later I mentioned here that playing SWTOR and seeing how they tied an interesting storyline with traditional quest mechanics made it more enjoyable while reiterating that while I don’t think traditional quests need to be eliminated completely and can be made fun, quests still need to evolve.

On Saturday, I joined over a hundred other hackers at HackTO. This has become a regular event in the Toronto tech scene, thanks to excellent organizing by Leila Boujnane and Corey Reid. SoundCloud joined several other API providers, including Atomic Reach, Context.IO, FreshBooks, Shopify, TinEye, Twilio, Trendspottr, WordPress and YellowAPI. The idea behind the event is simple: find a team (or go solo) and build an app using one or more of ..

Hi All, Just submitted an update for the BBC News Mobile app, this fixes the issues around live tiles. I’m going to hold my hand up to this one, it was a fault when moving between SVN and TFS. The backgroundscheduler code in the last version was actually from an older release and this caused the issues. I’ve also added in a beta feature for related articles, this is to shut up my housemate - Dan, who has been hassling me to make this ha..
