Undoing the effects of editing your entire repository

Tue, 01 Jun 2010 23:42:46 -0800

Towards the end of God of War III, we were spending time in the office at odd hours, often coming in late due to midnight oil debugging sessions. It's always somewhat unsettling when you've got people standing at your desk when you arrive in the morning and want help before you even had your first cup of coffee (I know, they do this at their own peril, coffee mellows me out). This particular day apparently someone had managed to check out the entire repository for edit and since we've got a exclusive lock policy in place for our maya binary files [1], this caused the entire studio to grind to a halt.

Development Tools

Sun, 29 Nov 2009 17:58:41 -0800

In your day to day usage of the computer you might find yourself wishing for that one tool that can help you do this particular task at hand. Chances are that it has already been written and the only reason why you are not using it is that you have not found out about it yet! I find this particularly annoying, since my Google-Fu is not that strong (luckily I work with people with strong Fu). But anyhow, this is a short list of tools that you absolutely have to check out, if not use. I'm going to assume that you are a windows shop and a game programmer for this list to apply...

Is quality going out of fashion?

Sat, 28 Nov 2009 21:09:56 -0800

A lot of times it's very useful to have your users drive whenever you are looking for bugs or problems at their computers. Even though I'm a very inpatient person when I look at somebody else searching for the key 'A' on their keyboard or moving the mouse slowly to cut and paste through the menu, you have to preserve and look at what they are doing since often what they are saying that they are doing and what they are actually doing can be very different. So every now and then I'm standing behind someone watching what they are doing and my jaw drops. Once someone were in the middle of doing things and the application just crashed. Very quickly the user clicked on the dialog box that said it crashed and relaunched the application, ready to continue with whatever we were in the middle of. Without batting an eye! This happens on occasion and I see it more and more. I call it the windows syndrome.

E3 is coming up around the mountain and since we're showing at the show this year it's naturally a little bit stressful. It will soon be over though and looking at the swine flu, perhaps not that many attending in person this year. Amidst all this, I realize that I have several projects in the pipe, in my "spare" time, one of which is this blog. Most of these projects have been neglected of late, even the weekly online gaming session. Which just frankly stinks a little bit, but let's do something about it!

GDC 2009, aftermath

Tue, 31 Mar 2009 20:58:49 -0800

I've gotten numerous requests for the slides for the talk me and Vassily gave at GDC 2009. Here they are for interested parties.

GDC 2009

Thu, 19 Mar 2009 21:34:04 -0800

GDC is around the corner again and people are starting to get excited about getting together and get some new ideas and share knowledge. I on the other hand have started to get increasingly nervous about this year’s GDC since I for some reason decided to give a talk. The reasoning behind it eludes me as the stage-fright is starting to increase.

The only game in town

Sun, 28 Sep 2008 17:29:06 -0800

There has been a little bit of resurgence for functional languages, I myself have on occasion spoken for functional languages, as have Christer Ericson and severalothers. Functional languages just makes sense in a way that you really can't appreciate until you've dabbled a little bit with them. The elegance of it all takes my breath away.

p4branch

Sat, 13 Sep 2008 01:31:23 -0800

Oh no! Not another perforce post. Spare us. We're not even using perforce anyways. Uhm. Have those guys left? Ok, well then for the rest of us that are left, I'm going to assume that you either use perforce happily at work or you are forced by some guy to use it. If you're the latter, then you might look envily at other modern source control systems that literally run circles around this old beast. I'm not kidding, running circles really means that you in other systems have adopted branching as the most basic operation you do.

Finding the right license

Sun, 31 Aug 2008 15:22:38 -0800

Recently I've been forced to look more and more at licenses for third party software that I use. This is in my opinion a complete waste of time and just a justification for more lawyers. Reading any license text is like reading the most boring end dense textbook you could possibly find on a trivial subject, and manages to make the subject incredibly complicated and hard to understand.

Tales of Vesperia

Thu, 28 Aug 2008 23:44:29 -0800

I got really excited that Tales of Vesperia was finally coming out (come on, a wolf with a pipe that fights with a sword, what more can you need?). I played Tales of Symphonia on my Wii, since it was listed as one of the all time best GameCube games and I really liked it, apart from it's obvious dated graphics. So when the news were that there was to be an HD version of that game coming out, I was all excited. Oh, foolish me.

Usercontrols in C#

Sun, 17 Aug 2008 22:55:43 -0800

So once again the curse of non trivial toy examples strikes. After spending about an hour trying to place a custom usercontrol onto a simple windows form in Visual Studio and C# I give up. In the most trivial example that I came up with it works fine, but as soon as I try to do this in my own little project (niftysolution plugin) visual studio does nothing but crash every time I try to drag my wizard generated empty user control onto the canvas of my slightly modified form.

More perforce tips

Sat, 02 Aug 2008 12:50:34 -0800

The source control history is a precious asset. How your source code evolved over time, what and who made the changes (and why) are questions that can all be answered by the history. It's important to try to preserve the history, but it's also very easy to forget and not do it. It is very frustrating to do some detective work only to find out that the trails end cold when someone copied the file without telling perforce. Best of all, the person who did this might have quit and you have now no clue as to where that file originated.

p4v for the lose

Sat, 02 Aug 2008 01:05:44 -0800

I guess I made the last post a little bit of a holy crusade and while I guess that is just fine for a blog like this I did just throw it out there that I hate the non windows look and feel of the p4v application without any motivations, so I decided to just download the thing and rediscover how crappy it still is and write it down this time.

p4win for the win

Fri, 01 Aug 2008 01:55:57 -0800

Perforce have had a strange development over the last couple of years with their UI clients. Perhaps not so strange from a manager's perspective or even a marketing perspective...

Are you bilingual?

Mon, 26 May 2008 19:42:07 -0800

I think the pragmatic programmer advices you to learn one new programming language each year. While this sounds perhaps plausible, I think this can be unattainable for the average non genius depending upon what you define learning as. Much like chess, programming languages are complex yet deceptively simple. You can teach the rules of chess to a novice in matter of minutes. Indeed within the hour a complete novice could be playing games on his/her own. Of course the games will usually end in disaster (and perhaps tears depending on age of the player). To learn the syntax of a new language is pretty easy. With reasonably good memory you could probably do this within a day for a simple enough language (i.e. not C++). If we call this learning the language, then sure we can follow the initial advice, but what would the point be? That would be aching to just memorize a new table each year to stretch your memory muscles.

Let me count the ways I size thee

Sun, 25 May 2008 19:30:27 -0800

Every now and then I go to the local electronics shop and just ... well, wander around for a little bit and see if there is anything that I'd like to buy. Anything that I do buy is of course completely unnecessary and I really shouldn't. This time around I had the feeble excuse that I needed a rather long TP cable. 30 minutes later I came out with the TP cable... and a 750 GB (bogus gb) harddrive. They had a sale and the price of $110 was kind of nice so I bought one.

Matrices are from Venus

Sun, 18 May 2008 23:20:56 -0800

Matrices seems to be some of the most misunderstood concepts of games programmers today. One does not even need to go into quaternions to find that just regular 4x4 matrices are surprisingly misunderstood.

Stupid C++ tricks

Wed, 30 Apr 2008 00:18:25 -0800

A while ago Charles Nicholson wrote an article about how they handled asserts in their engine. I kind of liked the title "Stupid C++ Tricks" and it triggered this article idea. Then since of course Noel Llopis managed to beat me to it, that after I've given him a hard time about his infrequent posts :) So without dwelling too much on why there are so many books and articles about traps, pitfalls, stupidity and secrets regarding C and C++ here you go; some more stupid tricks, don't try this at home.

Clearly you must be joking

Determinism in your tools

Tue, 29 Apr 2008 22:58:59 -0800

Determinism in the game itself can be used to easier reproduce bugs, gather performance data and even for gameplay itself. In modern games it does take a little bit of work if you have not had continuous tests during development to catch errors like when a game diverges. Recently I've had to do this as part of our graphics tests at work where we run the game in a special test mode and make sure that recent changes have not broken any rendering features.

Comparing images

Sat, 29 Mar 2008 22:44:04 -0800

It's hard to automate testing for graphics programming, most of the times you are looking for something that looks nice or good and you are forced to rely on just eyeballing it. Worse, you might need an artist to take a look at it, since programmer art is a fickle thing. There are some things that you can automate though and the fact that the computer is a cool analytic machine that has no concept of what looks good or bad is actually working to our advantage.

Perforce tips

Tue, 25 Mar 2008 23:08:34 -0800

How do you use perforce? Some like to stuff as much as possible in the repository, in the hopes that it will be useful to have it all in one place. Others like to keep it minimalistic as to not bog down the server too much. I've already written a little bit about the things that might be good to consider setting up a perforce server, but once it's up and running you might want to have a look at how you are using it.

iPhone SDK demos impresses

Fri, 07 Mar 2008 00:03:29 -0800

I just finished watching Apple announcing the iPhone SDK. If you have not watched it yet, I recommend it if you have about an hour and 20 minutes to spare. If not, you could just skim through this article instead for my impressions.

Finding a regular expression library

Mon, 03 Mar 2008 22:21:26 -0800

Regular expressions is somewhat of an oxymoron. They are anything but regular, they are strange beasts that you can write wonderful things in that you won't understand fully yourself after you've written them. I blame (as most things) perl for most of the evolution of regular expressions, they ones contained in perl are very powerful, but with great power comes an awful lot of ~~responsibility~~ spaghetti.

Vista Is Unusable

Thu, 31 Jan 2008 22:01:05 -0800

Windows Vista is, in retrospect after trying it out for a couple of months, simply a skip me version of Windows. I can just note my own folly in buying it.

p4shelf

Sat, 26 Jan 2008 17:35:04 -0800

I'm a big fan of continuous integration, small checkins and very quick checkins. It's easier to debug afterwards and trying to puzzle together from perforce history afterwards is much easier when the changes are small and atomic. Now, that's what I like to do. Sometimes things don't really work out in the real world like you want it to so the other day I found myself with the fun situation of having two weeks worth of changes to try to integrate back into the main line. Of course nothing was backed up, nor did I feel particularly worried about it at the time. I had however done a lot of work, some of the changes involved the fruits of heavy thinking and other changes were the result of an hour or two of menial changes to the code that was a result of some other change.

Stomping on dialog boxes

Sun, 13 Jan 2008 13:11:20 -0800

Have you seen the default crash dialog in windows? It's a dialog that's pretty much useless for the normal user (I always just click go away when it happens for other applications) but it's very useful for your own applications. For example, you are debugging some arcane crash that only happens deep inside the content pipeline. It can be tedious to make a reproduction case, that's small enough so that you can run it standalone in the debugger.

#include

Sun, 06 Jan 2008 18:24:21 -0800

Windows.h must be the worst engineered header of all times. It's a meta header, designed to include several others and these are usually so bad that I'm wondering if anyone at Microsoft ever learned to program in a larger environment (ironic is it not?).

Is Vista Unusable?

Sat, 08 Dec 2007 23:29:33 -0800

There is some debate regarding Windows Vista, Microsoft's flagship that is supposed to be the answer to Apple's MacOSX. After trying it out for a couple of days now I can only come to the conclusion that OMG it's bad. It not only looses by a wide margin to MacOSX, it stands no chance against its supposedly older sibling Windows XP. There are a lot of nice features that I do like, foremost the proper support for running as multiple users smoothly, running as a non root user and then installing programs as root. Nice. Now we've caught up with UNIX who had it, ah 1970 or so...

Comparing std::sort and qsort

Thu, 06 Dec 2007 22:11:36 -0800

I'm going to do something different today, instead of bashing on C++ as I usually do, I'm going to point at some good things about it. In fact, it's even involving templates, my old archenemy (Bowser is nothing compared to them). So while I'm happily downloading The Orange Box on Steam, I'm writing this very quick and dirty post.

Is PS3 development hard?

Wed, 28 Nov 2007 01:25:05 -0800

It's a little bit disappointing to see that the industry still are clamoring and lamenting the (supposed) difficulties of developing for the Playstation 3. Meanwhile, the consumers must be either thinking that the PS3 is a load of crap, or that the developers are. I can't really decide if they are correct on both accounts or if we as an industry have to get over ourselves and just stop whining and get to work. Now if it was easy to develop top notch video games, then they wouldn't need us, right?

Assembly Safari, Part I

Mon, 26 Nov 2007 23:17:36 -0800

Ever since I took the leap from Basic V2 to 6510 assembly on my old Commodore 64, I've had a hate/love relationship with assembly. It allowed me back then to do things that were not possibly through any other means (vblank handler, raster coppers etc). My second foray into assembly was through Turbo Pascal funny enough. Turbo Pascal had this really easy mechanism to escape into inline assembly so that you could write your high level constructs in Pascal and then write the guts in assembly. This worked really well for me for a long while, even though real mode x86 assembly is kind of a pain.

NULL, how I hate you

Sun, 28 Oct 2007 21:29:25 -0800

Every now and then a discussion about NULL comes up. Much like operator overloading of multiplication of a geometric vector class. In the course of the discussion many questions and theories are covered, I'd like to give my views on them here in this short article.

Static initialization in C++

Sun, 28 Oct 2007 21:00:32 -0800

In one of the murky corners of C++ we find all the rules for static initialization hidden. They hide here because they are hideous, deformed and frightening. If they were out in the open, noone in their right mind would start down the path of actually learning and using C++. Or so I would think. Anyways, if you're with me in the boat of "we're already screwed and we have to use C++" then read on and we'll try to put some pretty clothes on the monsters instead.

Writing math for the web

Fri, 19 Oct 2007 13:08:34 -0800

For writing math papers I always use Latex, it's really the only thing that can be used in a sane manner. As a programmer I kind of like it as well, since it's very easy to structure your document and you get a lot of things just for free, that seems to work poorly or is right down broken in other so called word processing softwares. For writing mathematical notation it's great. It's not all like the editors like Microsoft Equation (in the office suite) or Mathematica's one for that matter. No, here it's fairly straightforward and writing more complex things are a breeze.

Prehistoric demos

Moved blog

Tue, 16 Oct 2007 21:50:08 -0800

The old comment system I had on my blog was kind of dated and convoluted. A friend of mine complained a little about it and I set out to see if I could improve it a little bit. Whew. What a can of worms (thanks Nick). Turns out that in order to fix it I needed ssh access to my webhost...

Class instance initialization

Mon, 15 Oct 2007 12:36:27 -0800

I thought I would ramble on a little about the class constructor in C++ as well as start a new topic in the blog, C++. Here is the first installment. A little random, but fun facts. Keep your copy of the standard close by.

Warning for sloppy code

Sun, 14 Oct 2007 14:24:57 -0800

One of my (maybe bad) pet peeves are compiler warnings. I try to compile cleanly at the highest warning level and go through all the warnings one by one and really understand what they are fuzzing about. And then fix them. The reasoning behind this is that the compiler writers are usually much much better at the language than I am. If they bother enough to put in a warning message, then there is probably a catch somewhere. Dismissing it out of hand as stupid is done at your own peril. Every now and then there is some subtle gotcha that the compiler writers understand but you have yet to grasp about the language. And boy do you feel stupid after a monster debug session only to find that the bug you were searching for was already flagged by the compiler in a warning that you ignored!

BadgerConfig

Fri, 12 Oct 2007 21:45:31 -0800

For a couple of years now I've been using a system to manage visual studio projects and solutions automatically. It started out as a massive upgrade operation moving from visual studio 6 to 2002 at the time. In order to do this I decided to also generate all the projects automatically since it was such a pain to maintain them manually. I also didn't trust the settings in the current projects since they were all different from project to project. So I decided to move ahead and write these scripts to handle all the generation for me. Something wonderful happens when you can add files to your project and even projects to your solution with minimal work. It eases the pain to add things in their proper place, instead of just adding functions in some unrelated files (have you stumbled upon filename manipulation routines deep inside your AI?) you can take the trouble now to add the files to the project with proper names. You can also easily add new projects to keep separation into libraries sane.

Choppers 2D prototype

Wed, 03 Oct 2007 13:15:09 -0800

Since I try to do video games for a living, it might seem very odd for me to go home and then do the same thing again. I call it recreational programming and in all honesty it's a little bit whacked. I'm not alone in this though, I know a lot of people do the same thing, or similarly taking their day job home and doing it as a hobby. Either we're really lucky or just retarded. Any given day I'm in the balance which. Anyhow, this article starts at a lunch with a friend where we start reminiscing about old games and what we played back in the day before monster processors and even consoles more powerful than the NES 8-bit system. Several games came up but one stuck in the conversation and kind of expanded. The game was Chopper Duel, for the old DOS computers. The game is not that old, but the idea came up to do a revamped version of the game, in full 3D and with destructible environment. Well, suffice to say I didn't make that game.

Spam Ohoy

Sat, 22 Sep 2007 22:42:16 -0800

It finally happened. I'm starting to get Swedish spam (well, obviously email one, not that pig meat thing) to one of my actual email addresses. Then world is ending! Seriously though, WTF. I just wished that people started to stop clicking on these infernal links. I mean, if someone is willing to pay some amount of money for each email, or just each click originating from a particular email, all we have to do is to stop clicking, right? It's getting ridiculous. We are now having the neural nets we just so touted that would do awesome things to just sort our emails for spam.

Build Configurations

Sat, 22 Sep 2007 21:30:58 -0800

There are some things that you take for granted but then again you meet blank stares when you talk about it as it was a given. It is very easy to forget that some things that you take for granted, others have not yet seen or thought about and vice versa. We're all colored by our own quirky way through the maze towards programming enlightenment. My own path has taught me the following of build configurations: Debug and Release are not enough.

Apple Safari on Windows

Mon, 10 Sep 2007 00:00:34 -0800

I ran MacOSX early on my G3 laptop (now retired) and I loved it. One of the things I really loved was the way Mac rendered fonts. They are really completley different than the way Windows does it. Now I recently found out that I can run Safari (the native browser on MacOSX) on my Windows machine.

Namespaces, lookup and ADL

Sun, 09 Sep 2007 23:32:10 -0800

C++ has a lot of nasty corners that smell a lot as well as some remarkable things that can be used in some fairly suprising manners. One of the little understood corners of C++ is name lookup. Name lookup is something very basic but the basics seems to be the things that people skim over when learning C++ or just using it. Things like L-values and R-values are part of the basics and they are sadly little understood.

Reverting a perforce changelist

Wed, 27 Jun 2007 00:03:43 -0800

Sometimes you wind up with changes in your source control system that shouldn't be in there, or you hit the submit button in perforce when you really meant just update the description. Anyways, you find yourself with a changelist that you want to roll back...

Cell Symposium Atlanta, GA

Fri, 22 Jun 2007 00:14:44 -0800

Monday I was on the east coast giving a short talk on CELL, games and languages. The talk itself was a little bit of a rant of mine, covering games development and games developers' love of C++. Love hurts. The venue for the talk itself was the CELL Symposium at Georgia Tech, Atlanta.

Desktop Commander

Thu, 21 Jun 2007 23:00:26 -0800

I've got this dual monitor setup at home, a widescreen monitor and a standard aspect monitor rotated 90 degrees. Every now and then I'd like to change my desktop background and I have quite an extensive collection of images that I've taken that I'd like to rotate around. So how do you do it?

The performance of map v/s vector

Sun, 22 Apr 2007 20:07:08 -0800

STL has an unfairly bad reputation in games development circles in my opinion. People that got burnt on the old HP stl that shipped with gcc 2.7.x series was on many platform the norm and that particular implementation coupled with the poor compiler probably left a sour taste for many developers. I think STL as many other things has a place in C++ development, for tools certainly it's a productivity boost and as many of us run their tools on the win32 platform, most of the concerns that we have on consoles are not the dominant part of execution time.

NiftyPlugins source code

Wed, 04 Oct 2006 23:49:49 -0800

A couple of days ago, Noel emailed me about the source to NiftyPerforce since he wanted to make some changes to it. At this point I only had it on my local subversion repository. I'd heard about this cool feature google recently put up, which should be interesting place to actually host a "real" project...

Dice

Sun, 01 Oct 2006 21:09:52 -0800

My very good friend Andreas Brinck and I have been working for some time now on a hobby project on our spare time. It all started out as a very large project, we had a game design and all for a rather ambitious platform game. We quickly realized that we would not be able to pull it off with just two programmers, so we kind of changed gears and decided to try a simple puzzle game with minimal art resources....

NiftyPerforce

Thu, 21 Sep 2006 22:48:25 -0800

Visual Studio is the tool that most games programmers come to use for their day to day work. Perforce also seems to spread amongst games companies as the SCM system of choice. On paper Visual Studio also have source control integration. Great, now everything just happens automagically! No need to think about those mundane issues, I can just concentrate on the code. Well, that's wrong. You do need to concentrate on the "mundane" issues. One of the things that annoys me to no end is the fact that when you have the SCM feature enabled the time it takes to open a solution...

UnitTestCg

Tue, 19 Sep 2006 22:23:17 -0800

Ever after the radioactive TDD bug bit me and I'm now infected with that mode of development I've become more and more interested in good unittest frameworks to help me develop bugfree code fast. If you have not yet experienced Test Driven Development, I'd recommend reading up a little bit on it before continuing with this article, see the resources at the end of the page. One thing that still is lacking is a good solid unittest framework for shader development...

Working offline with perforce

Thu, 14 Sep 2006 23:47:29 -0800

One of the annoying things about perforce is the need to be connected to the perforce server at all times. Manipulating files underneath perforce is a recipe for a world of hurt and pain. But there are times when you want to do just this, say you're on a trip with your laptop and of course there's not WiFi hotspot where you are just now, but you still want to code something and later on check it in.

Lint hidden in the PSDK

Mon, 21 Aug 2006 22:01:51 -0800

I remember back in the day when I started programming C++ on the IBM computer there were a plethora of compilers out there. Borland Turbo C++, Visual Studio, djgpp and my favourite Watcom C++. Watcom was my favourite because it's optimizer and it's powerful inline assembly features allowing you to specify exactly where arguments were passed in registers and dirty registers. The debugger was also good (at least in my memory). We used a freeware extender for flat mode instead of the one supplied with Watcom (which you had to pay money for).

Writing portable code

Wed, 09 Aug 2006 23:32:13 -0800

Here are some tips for writing portable code. Some of them may apply to your project and some might not, think before you choose and if you're going to make any "stupid" decisions, make sure that you are making them deliberately and with open eyes. It might be ok for your project. And of course if you're never ever cross your heart and hope to die going to port your code to any other platform than the current (you lucky dog) then just disregard everything in here and go home earlier and enjoy a cool beer on the balcony, in short do something better than sit in the office all day.

Perforce diff and patch

Sat, 05 Aug 2006 22:25:39 -0800

I'm sitting here in my apartment amongst boxes and boxes, still unpacked from moving from San Diego. Moving is always a pain and this time is no exception. Packing all your stuff takes some time and unpacking takes even more time since you have to figure out where to place stuff, now in the new place you don't really know where everything goes. Speaking of packing and unpacking (nice dissolve, eh? :) doing the same for your changelists in perforce should be a breeze. The command 'p4 diff' actually outputs some interesting information, amongst them a full description of the differences of the currently checked out files. Unfortunately the output is not trivial to reapply again. Well to the rescue comes two little python scripts!

Exploring the ellipsis construct.

Wed, 02 Aug 2006 00:24:24 -0800

One of many wierd constructs in C++ is the ellipsis construct (...). That's a way to specify that there might come a variable amount of extra parameters after the one that you give. Underneath there is no real magic, the parameters that you specify are pushed onto the stack and then inside the function you can traverse the stack. There are some catches with this though. In this little article we'll explore how the ... works and what not to do.

Noel and I gave a very informal talk on "XP and Scrum in Games Development" the other day (June 8) at the XP San Diego.

Automation with visual basic

Sun, 14 May 2006 20:04:00 -0800

I think one of the most overlooked aspects of Visual Studio is it's extensibility through visual basic for applications (VBA). This is a little discussion about some simple scripts that help me through the day with visual studio. The code is kind of horrible, since I'm really not a basic writer at all but bear with me here.

Installing a new perforce server? Here are some tips that you might want to look into after installation.

Memory adventure safari

C++ is hard people say. Program in some other language. Like Java or C#. When asked, people who champion these languages usually agree that the garbage collecting is godsent and that memory management is a mess in C++. While I'm not disagreeing that sweeping the memory problem under the rug is kind of nice (hey, I do a lot of python programming) I don't understand why memory management should inherently be difficult in C++. There are ways to shoot yourself in the foot, several times with a bazooka. But there are also relief. There are some simple rules that you can follow to minimize your allocation hell. We will discuss some of them here, as well what to do when everything falls down on your head and you wind up with a memory leak. It's a little bit of a jumble, a little bit of an safari as the title suggests :)

Detecting hotload changes

Wed, 15 Mar 2006 23:17:32 -0800

Hotloading was for a while, well a hot, topic in the game development industry. As games progressed from being very simple programs to more of world simulators today the issue of tweaking and how assets are handled became more of an issue. When your data fits on a standard floppy disk it's not that bad, but when you have your system administrator breathing down your neck because your using up a Gigabyte of disk each night things become complicated.

Continuous integration with CC.net

Tue, 14 Mar 2006 22:02:10 -0800

So what's wrong with the "traditional" way of having a group of developers write code, checkin and get latest in isolation? It's been working for several projects, right? So why should we fix something that isn't broken? Well, I could argue that it is broken. I obviously don't know what kind of problems you have at your company, but I know that in the past I've been faced with broken builds and didn't even know that it was a problem until much much later.

Static data for unit tests

Thu, 09 Mar 2006 00:17:12 -0800

Bringing data into your program is always a source of problems. Problems like filesystems, paths and unreliable system calls sound familiar? These problems are not the ones you want to battle with in addition to your unit tests. There is light at the end of the tunnel though. Static data in the executable. We've all done it, quick hardcoded tables inline with the code. Taking it to the next step is simply integrating this into the buildstep and creating these tables from ordinary data, bypassing the filesystem at runtime completely.

Tools for python programming

Wed, 08 Mar 2006 21:25:48 -0800

This little article will explain how to setup an environment for developing python programs. It will explain the different components and the workflow for developing slightly larger programs in python since the small tutorial ones are pretty much covered and they always (in my opinion) leaves out the really hard stuff.

For a long time now I've been using Honk's (Henrik dot Karlsson at dice dot se) FastOpen plugin for accessing files in Visual Studio quick and easy. Yes, there is Visual Assist to consider as well, but historically it's been buggy and slow (they might have fixed that now) so I've kind of shied away from it. So I though it was a good time to explore a little how the plugins in the new visual studio works and a little practice with C# as well to boot.

Launch of new blog.

Sun, 12 Feb 2006 17:41:47 -0800

A while ago I started to think that my webpage was a little bit drab looking and lacked the any comment system. So I started to look into how people was doing it nowadays and even briefly considered writing my own system (horror!). Luckily I quickly realized that it was a pretty large project which I didn't particularly wanted to take on. I just wanted a simple system that could satisfy my needs of a comment system and easy to maintain...
