Problem 1: Connectivity

Trouble connecting to other players. Errors like the other player has disconnected or similar that stops the game before it actually begins.

Solution

In most situations this is probably caused by people sitting behind a router. When your opponent tries to connect to one of your ports, and you’re behind a router, the router will not carry the connection through unless it’s configured to do so. So you have to tell the router to forward requests for certain ports to the machine running Fifa 10 – something called Port Forwarding.

The ports you need to forward are (taken from the manual page 17)

• TCP/IP: 30440-30449
• UDP: 3658, 3659, 9570

I’ve omitted the ports 80 and 443 because you don’t need to forward those – or you shouldn’t.

Problem 2: Players quitting the game prematurely

If you’re losing the game, this is not a problem at all. So if you’re losing all games you need not read this section. However, if you’re winning a game against a poor sportsman, that person will quit the game before it’s over. This can be extremely irritating, and will cost you a win in the statistics unless it’s near the end of the game – in which case you’ll be awarded a win anyway.

Solution

Do not play opponents with a DNF (did not finish) of above 8%. This is absolutely crucial. Especially opponents with a lot of games played (say 200) that have a DNF of above 5% are very likely to be quitters.

It also helps to play opponents that match your skill level. In the online menu you can choose CUSTOM MATCH and then Create Ranked Session. The subsequent screen lets you choose only to play opponents that have a DNF of 10% or lower, and even opponents of the same skill level as you.

Use that and be picky. It’s really worth it getting a good game instead of getting a lot of worthless games that are ended prematurely.

Problem 3: Games are lagging

The games are lagging. It takes a while before a command issued to a player is carried through. Periodical lagging.

Solution

Be picky. In a lot of games you can’t see the opponent’s ping. Try asking about what it is, and if the other player can’t read, just find another game. I only play games with a ping below 85ms (or around that) simply because it’s no fun to play slow/lagging games.

Be sure to use your geographical knowledge as well. If you can spot that the flag of your opponent indicates that he’s located very far from your own location the game will probably be lagging, just because of the distance the information has to travel.

I’ve deployed the `Magic: The Gathering` Engine which is now available via

http://magic.ratio.dk/home

Basically it’s a deck builder that takes the prices of cards into account. It took some work to get it up, but I’m rather contend with the result. In any case I hope I’ll be able to take advantage of it when building decks in the future.

Hopefully others will find it useful!

Non-full hard drives are a nuisance to me. That being said, I’ve been looking into different ways of combating this phenomenon. Here’s a couple of solutions that don’t really work.

1. Find something useful to do with the free space like writing poetry in weighty Word documents that take up a couple of megabytes for each file.
2. Ignore it and rejoice because it’s nice to have free space, why not?
3. Enjoy life and drink plenty of coffee.

Only one of these options is really feasible, and while it might be a good bet, it’s also possible to combine it with the correct answer to the question posed a long time ago.

On a Windows XP SP3 installation you will have access to the recommendable program that is fsutil. It comes with the system. For the sake of the example, let us say the drive letter in question is D.

fsutil volume diskfree D:
This will print you the amount of free disk space free in bytes. Let’s say the number of bytes free is 1234567890, why not. That’s just over a gigabyte! Now copy (or remember if you’re so inclined) the number of bytes free, and let your fingers dance to this command.

fsutil file createnew D:\MY_FILLER_FILE 1234567890
Discounting external factors the D drive will now be full – not just close to. Incidentally it might be a bad idea to do this on the system drive (usually the C drive) as it’s very fond of disk space being free there. Try it though if you want Windows to suffer.

Note: Tested on Windows XP SP3 with the version of fsutil that come with that.

Could I please be equipped with a DC output in the next version? Seeing as I enjoy eating and thus generating far more energy than needed to sustain my bodily functions, it would be a neat feature. I’m sure there’s lots of other people in the industrialized world who would benefit from this as well.

It goes through the steps of

1. Encrypting a partition
2. Putting the key on a USB stick
3. Auto-mounting the USB stick with the key at boot up
4. Making sweet coffee

Now I think I’ve used up today’s quota of English gibberish.

Thanks for reading thus far :).

“To unbuntu” is the act of changing away from using the Ubuntu operating system. As such “to unbuntu” could refer to installing Windows 3.1 replacing an existing Ubuntu install.

Before we go into detail on how it’s actually done, let’s take some time to reflect upon what we shall expect of this server:

• No need for having UNIX users in order to log in
• In particular do not allow UNIX users to log in
• Jail users into their home directory
• Make delicious coffee

First become root with

su

or

sudo su

if you’re on a weird system (e.g. Ubuntu).

Fetch the package typing

apt-get install proftpd

The installer will ask you if you whether you want it to run on top of inetd or as a standalone service. Choose standalone because the other is rubbish or at least not very good (thank God this is a blog, so I don’t have to justify my opinions!).

Editing the Configuration File

Next up is the configuration. I won’t go into irrelevant features such as virtual hosts, but if that’s what you want you’d best check out the example configurations at the official site. They’re actually pretty explanatory.

Start editing the configuration file using your editor of choice. This example features emacs.

emacs /etc/proftpd/proftpd.conf

The order in which the following is written is not important. It is important though, that it does NOT get stuck inside any XMLish tags such as …

This is what my /etc/proftpd/proftpd.conf includes:

# enable virtual users' shell to be /bin/false
RequireValidShell off
# disable logins from UNIX users.
# to enable UNIX users too,
# add mod_unix.c to the space-separated list
AuthOrder mod_auth_file.c
# auth files
AuthUserFile /etc/proftpd/ftpd.passwd
AuthGroupFile /etc/proftpd/ftpd.group
# jail the users in their home directories
DefaultRoot ~

The alert user instantly notices the files /etc/proftpd/ftpd.passwd and /etc/proftpd/ftpd.group. They are the virtual user equivalent of /etc/passwd and /etc/group which are the files Proftpd would have used had we not told it otherwise. Other than the fact that they share the exact same format, they are in no way connected in our setup. Proftpd doesn’t know about any other password/group files than the two specified in the new configuration file.

Creating the ftpd.passwd file

If you’re not into editing the ftpd.passwd by hand, you can use the ftpasswd script made available from http://www.castaglia.org/proftpd/. At the time of writing it can be obtained using

wget http://www.castaglia.org/proftpd/contrib/ftpasswd

It is a Perl script. First make it executable

chmod +x ftpasswd

The usage example featured here has will make a user with the username ‘john‘ with user id ‘1‘ and group id ‘1‘, having a disabled shell and save this user to the /etc/proftpd/ftpd.passwd password file.

./ftpasswd --passwd --file=/etc/proftpd/ftpd.passwd --name=john --uid=1 --gid=1 --home=/home/ftp --shell=/bin/false

The next user should have a different id (e.g. ‘2′).

To allow users to modify files you can choose to make it writable by any user of the system. Recall however that you’ve already jailed each user to his/her home directory, so the damage potential is rather limited. My example uses the /home/ftp folder as the home dir, so let’s remove the restrictions on that directory.

chmod 777 /home/ftp

Now all that’s left to do is restarting the server.

/etc/init.d/proftpd restart

If you’ve read this far I really hope it’s working for you! If not or if you have rants/comments about this guide, feel free to vent in the comments-section.

1. HTTP/DAV
2. svn+ssh
3. svnserve

On my server I’ve chosen svnserve since (1) HTTP/DAV is just too heavy for my limited purpose and svn+ssh requires me to add UNIX users for every user of my repository. svnserve on the other hand is really simple to setup, and it doesn’t require any additional software such as an Apache web server.

First we need Subversion:

apt-get install subversion

This package includes svnserve, so naturally we’re ecstatically joyous already. Incidentally I like having my Subversion repositories situated in /var/svn/, so let’s create a repository here.

svnadmin create /var/svn/MyRepository

Next up is the configuration. We start by editing svnserve.conf using some text editor capable of editing. Personally I prefer emacs for this task.

emacs /var/svn/MyRepository/conf/svnserve.conf

This is what it could look like.
[general]
anon-access = none
auth-access = write
password-db = passwd
realm = MyRepository

Line three (password-db = passwd) requires follow-up, since it says we’ll be using a password file called passwd.

emacs /var/svn/MyRepository/conf/passwd

My preferred token name is “john” and his password is “secret” apparently.
[users]
john = secret

All that is left to do is starting svnserve.

svnserve -d --listen-host example.com -r /var/svn

This will start svnserve in daemon mode (-d) with /var/svn as its root (-r). Thus MyRepository will be accessible via

svn://example.com/MyRepository

using the username john and the password secret. As it happens any other repository situated in /var/svn/* will also be accessible via the svnserve daemon.

I prefer to keep my audio files named as such:

Artist/Album/01 Name of Song.mp3

Achieving a consistent naming scheme requires either loads of time and patience or a genuine power tool. I have found that Bulk Rename Utility is a indispensable tool for almost any file naming job, and it is thus highly recommended.

ID3 Tag Editing Including Album Cover Embedding

With regards to ID3 tag editing there are two excellent choices: Foobar2000 and Mp3tag. I do prefer the former, but only for the somewhat easier navigation. Foobar2000 does however not support album cover embedding. This concept enables JPEG images to be embedded in the ID3 tag of MP3 audio files, and is supported by Mp3tag.

It is even possible to automate the embedding if album covers if they reside in the folders of the albums. Suppose each cover is named folder.jpg. Drag all relevant folders into Mp3tag, select all the files and press Shift+Alt+5. Select Import Cover From File and type folder.jpg as the format string. The album covers are then automatically embedded in each audio file.

Using Foobar2000 for ID3 tag editing (Alt+Enter or right click followed by Properties) enables one to make use of the magnificent Automatically Fill Values feature. If for instance one’s naming scheme for files is the track number followed by a single space followed by the title of the track, then this pattern will fill those exact values correctly:

%TRACKNUMBER% %TITLE%

Conversion Between All Sorts of Formats

If one wish to convert massive amounts of audio files from one format to another Foobar2000 is the way to go. Like everything else in Foobar2000 converting is really easy. Just import the audio files, select them, right click and choose Convert followed by Convert to Same Folder (for convenience). If you want a file naming scheme that is not retarded you can choose More Settings and insert

[%tracknumber% ]%title%

into the Single tracks field.

The truth is there is no truth. If however one wish to bet on the winning horse, then MP3 is definitely the format of choice. Although MP3 is a lossy format and thus degrades the quality of your precious and costly CDs, it is still the most widely used and therefore supported by virtually all hardware- and software players out there.

Another possibility is to use FLAC. This stands for free lossless audio codec and so it is. However it is not supported by the major players including iTunes and iPods which make it good for nothing but storing your CDs on the computer for later conversion. With an acceptable compression level FLAC will take up half the space on the hard drive as uncompressed WAV files do. It is comparable to having the negatives from a film lying around for later development in whatever size suitable, which I find very settling given the perishability of compact discs.

The alert reader will notice that both the lossy and the lossless format I have highlighted here are in fact technologically inferiors. Monkey’s Audio is a technically better format than FLAC, and Ogg Vorbis beats MP3 when it comes to compression rates. Why then still highlight FLAC and MP3? Because availability is the only thing that is really important when it comes to formats. If my iPod (hypothetical remark, I don’t own Apple equipment) does not play Ogg Vorbis, then it isn’t really better than MP3 since it doesn’t work.

About Software Players

Over the time I have used a lot of different software players, because no one player had just what I thought I was looking for.

Foobar2000 (Windows)

As far as I am aware this is the most customisable audio player out there. All this flexibility however, comes the price of work on your part. Gradually as my needs changed I found it to be rather tedious having to invest a lot of time changing the player too. The player features

• An excellent ID3 tag editor for editing massive amounts of audio files
• An unrivalled conversion tool for converting FLAC into MP3 or WAV into FLAC
• Support for every interesting format
• Doesn’t try to do everything for you

SongBird / iTunes (Windows)

I am mentioning these two players in the same heading since they are very similar to my mind in their workings. The main difference I find is that SongBird is open source. As opposed to Foobar2000 these players are not very customisable but requires one to setup everything in a certain maner. They assume that their users are numbskulls which ironically means that it’s harder to figure out how to use them reasonably than Foobar2000 or WinAmp for instance. The features of these players include

• Looking good without too much work
• Feels finished (applies especially to iTunes)
• Easily navigated by friends who are not necessarily very tech savvy
