The first game I ever did in Shockwave is now available on my site! It’s basically a Risk clone but with a fewer features and reasonable AI. Play Supremacy

Supremacy is a Risk clone I wrote in Shockwave a while ago. I recently found it and decided to put it back for the world to see :)

Play Supremacy

It used the original 42 countries from Risk, has no continent bonuses or Risk cards. And has a few bugs regarding the number of reinforcements it says you have. It’s also quite fun to watch six computer players play against each other.

Following my post about ripping DVDs, here is a method for transcoding the DVDs into something more manageable. I should point out that is probably for the more technical amongst you - there are certainly easier ways to do it but this has the advantage of being very automatable.

Since MythTV (and Linux in general) seems to like ffmpeg for video encoding/decoding, I figured I’d use that. You can get a binary version for Windows and read the documentation.

The actual command line I use to transcode is: ffmpeg -i $in_file -vcodec xvid -qscale 5 -acodec copy $out_file

That means to use $in_file as input (a VOB file in my case), use the Xvid codec for the video, set the “quality” to 5, copy the audio straight from the original and save as $out_file. The quality in this case is just simplification of lots of other settings that are available. 1 is perfect and 31 is the worst. 5 results in files that are about 500MB per hour with MPEG artifacts that are visible when I’m sat at y desk but not when I sit on my bed six feet away which is where I normally watch video from. It may be worth transcoding a short clip with a few different settings to see which your happy with.

I made the whole process semi-automatic by writing a CLI PHP script that checks for VOB files in a specifc folder and transcodes the ones it finds. That way I can have the transcoding going on in the background while I rip the DVDs (and then leave it running it overnight to finish). I could make it available to anyone who wants it, but a batch files doing the same thing would probably be more useful for people…

There is one last caveat. I originally encoded the movies with MP3 audio and then half way though decided I want to keep the 5.1 audio (which the above method does). However the version of ffmpeg I used at first had a problem such that AVIs with AC3 audio played back with no sound. If you have a similar problem make sure you have the latest version of ffmpeg you can get.

Since I’ve decided to try and set up a MythTV system I figured getting my DVD collection on to hard drive(s) would be a good move for convenience.

There’s a lot of information on the Internet about copying DVDs, whether to other DVDs, to CDs or to a hard drive in their original format or transcoded. I wanted to get the main movie only from a disk and transcode it to XviD for space saving. Here are the steps I have that worked (for Windows incidentally):

The first step is to get the main movie from the disc. This isn’t straightforward since most movies are put on DVDs in a way to deliberately make it confusing to get them off. I used a program called DVDDecrypter (getting a hold of this might be a problem since the original author doesn’t make it available any more due to a recent change in his local laws). DVDDecrypter has a mode called “IFO Mode”. IFO files are the files on a DVD that contain information about how the chapters and program streams go together. The basic idea is to find the program stream that “looks right”. In the case of a movie, the one that’s about an hour and a half long (or two hours -whatever) should be the right one.

This process is pretty quick, about 8 minutes on my Athlon 64 3000 for a movie 100 minutes long. The result is a .VOB file with just the section you selected. A .VOB is really just an MPEG file with specific encoding setting and possible subtitle information. Many media players can play these directly.

In the next part, I’ll deal with transcoding the VOB files.

It should be noted that there may be legal considerations with this sort of thing. A lot of DVDs are encrypted and bypassing the encrpytion may or may not be illegal where you live (for example it’s skirting on the edge of the DMCA). In my case I own all the DVDs I rip and the rips are of a (marginally) lower quality than the originals, don’t have 5.1 sound and are missing all the extra features. As such I feel any concept of fair use covers me morally. You have been warned however and follow any of this advice at your own risk.

I’ve talked about the clever calculator features built into Google before. Most of my examples then were rather silly. Well I’ve started using it a bit more seriously recently. The great thing it does is allow unit conversions to be done effortlessly at the same time as the main calculation.

For example, I have a video clip that is about 350 MB and 45 minutes long. I want to know what the average bit rate for the encoding is, in kbps. 350 MB is 350 * 1024 * 8 kbits. 45 minutes is 45 * 60 seconds. Works those two out, divide the first by the second and I have my answer. Or just type [350 MB / 45 minutes in kbps](http://www.google.com/search?sourceid=navclient-ff&ie=UTF-8&rls=GGGL,GGGL:2006-22,GGGL:en&q=350+MB+%2F+45+minutes+in+kbps) into Google and I have my answer with far less effort.

In case you didn’t know, Stargate SG-1 has been “cancelled”.

To be specific the Sci-Fi channel in America has decided not to pay for another series after series 10. But all is not lost. According to Wikipedia they will be making two straight-to-DVD movies by the end of the year (filming in April and June). The first will wrap up the Ori storyline and the other will be unrelated (check Wikipedia for some spoilers).

Also another completely separate Stargate series is planned to start in 2008/

Like Linux in general, there are few MythTV distributions you can get. Unlike Linux in general, most of them have specific purposes they work best for. The three popular ones I know of are:

• MythDora
• KnoppMyth
• MiniMyth

MythDora is just Fedora with MythTV (and its dependencies). This is intended to leave you with a completely usable Linux installation that includes MythTV. It comes on DVD and is certainly the largest of the three.

KnoppMyth is either based on Knoppix or Debian (or really both) depending on how you look at it. Knoppix is a slimline distribution based on Debian and KnoppMyth was originally based on Knoppix. But I’m sure I read somewhere that the latest is version is just based on Debian but in the same way Knoppix is. Whatever the situation is, all you really need to know is that it is a minimal installation that leaves you with a fully functional MythTV installation but relatively little else.

MiniMyth is the smallest of the three and the most specialised. It only runs the frontend software and only the EPIA mini-ITX motherboards. Furthermore it is designed to run disklessly booting over a network - mainly as a silent set top box in your living room.

The only one I’ve actually tried is KnoppMyth which was easy enough to install. From what I’ve been reading they all seem easier than installing MythTV into an existing installation.

I finally (technically) installed KnoppMyth (a Debian based Linux distribution designed just to run MythTV) today. I say technically since I installed it somewhere where I couldn’t connect any sort of TV signal up to it. So, although it works fine, I haven’t actually managed to test any of the important features. The only part of the installation that was a problem was that the hard drive KnoppMyth uses must be the master device on the primary IDE channel.

I had it on the secondary and it was not happy.

Jimmy Wales, the man behind Wikipedia has decided to launch a search engine.

In a move reminiscent of the Open Directory Project, Wikia Search will be human edited. Beyond that, not much is known, but it will be. One of the core philosophies, according to a recent interview with Jimmy is that everything should be as transparent as possible - definitely a long way from the current search engines.

Star Trek: Legacy is a space combat game featuring the voices of all five Star Trek captains. The damage effects on the ships is good; in fact the graphics overall are very good.

But unfortunately the game is rather simplistic and terribly crippled by a dodgy control system. Which is a shame since it had potential.
