'Upgrade' Killed my ADSL

My ISP upgraded my ADSL to version 2+ and now my router won't connect. I tried all the usual troubleshooting steps of rebooting and unplugging the ADSL wire to no avail. Next I got on the phone to my ISP, Demon. Demon ran line checks during which I was disconnected. Humph! Calling back I had to wait in the queue again. Try to be calm. Take deep breaths. Demon persuaded me to buy three new micro-filters which had no effect. Finally they told me that they would have to pass the call to a BT engineer. To top it all they asked me to pre-approve that I would pay £170 if BT found that the fault originated in my house. Naturally enough I declined their kind offer. Only thing now is to wait until Monday to see if they can fix it. Until then we're back to 1993 and dial-up internet.

E61 Mercurial Solution

Mercurial to version control files on my E61 phone. That would be sweet. I could edit text in PED then push and pull changes from my server using SSH. Only problem is that, as of writing, there is no mercurial client for the Symbian S60v3 operating system. Mercurial is a combination of Python and C code. In my dreams of spare-time nirvana I could attempt a port to S60, but realistically that isn't going to happen. I need a plan B.

Engineering Compromise

So, I'm not going to be able to have a command-line like experience of mercurial on my E61. What about the next best thing? My next idea was to use putty to: (1) ssh into a directory on my linux server (2) Update the mercurial repos there (3) Grab all the files from the linux server to the phone (4) Make edits on the phone (5) Upload the modified files back to the linux server (6) From putty on the linux server commit the changes into mercurial I've got this working. The tricky bit was to decide what to use to move the files about. I've ended up with MobyExplorer doing FTP to my local linux box. Inside the firewall I felt the FTP was safe enough. I'm a little nervous at opening up an FTP server on my public facing boxes. I had to set up secure FTP.

Secure FTP Set Up

I installed the Very Secure FTP Server (vsftpd) using aptitude. I made the following changes to the config in /etc/vsftpd/vsftpd.conf (1) local_enable=YES (2) write_enable=YES (3) anonymous_enable=NO (4) chroot_local_user=YES ...then restart the server with sudo /etc/init.d/vsftpd restart

Why does cygwin pick up 'f' as my home drive?

I installed cygwin on my new work laptop. For some reason when ever I ran cygwin it said:

mkdir: cannot create directory `/cygdrive/f': No such file or directory
Copying skeleton files.
These files are for the user to personalise
their cygwin experience.

These will never be overwritten.

/usr/bin/install: cannot create directory /cygdrive/f: No such file or directory

/usr/bin/install: cannot create directory /cygdrive/f: No such file or directory

/usr/bin/install: cannot create directory /cygdrive/f: No such file or directory

bash: cd: /cygdrive/f: No such file or directory
Your group name is currently "mkgroup_l_d". This indicates that not
all domain users and groups are listed in the /etc/passwd and
/etc/group files.
See the man pages for mkpasswd and mkgroup then, for example, run
mkpasswd -l -d > /etc/passwd
mkgroup  -l -d > /etc/group

This message is only displayed once (unless you recreate /etc/group)
and can be safely ignored.
cp: cannot create regular file `/cygdrive/f/group.mkgroup_l_d': No such file or
directory

So, I must have got something set up incorrectly. Looking at the environment variables I see:

$ set
...lots of stuff
HOME=/cygdrive/f
...more stuff

So where is HOME set? The work laptop is running Vista and I'm farily new to it. Looked in Control Panel >> System >> Advanced System Settings >> Environment Variables, but there was no reference to HOME. Next stop was Google, obviously. It told me to edit /etc/passwd. Sure enough there was a setting against my username for /cygdrive/f. I changed it to /cygdrive/c/dave and it all worked great.

Video Editting Software

We were going to visit the National Media Museum, but due to son #2 getting a stomach bug on Saturday night that wasn't to be. Instead we made a video diary of the weekend. My camera records quicktime (.mov) files. I had about twenty of these to splice together by the end of the weekend. I didn't have a video editing program to use. A little wikipedia led me to avidemux. This seemed lightweight and just right for what I needed. To get a rough cut done to show the wife I just appended the files together. This worked fine, but after about three minutes the sound was a long way out of sync with the video. A quick scan of the avidemux wiki suggested I do Audio->Build VBR Time Map. I tried that but it didn't seem to do anything. Clicking somewhat at random, I don't know much about video, I tired Tools->Rebuild I & B Frames. That didn't help. I'm parking this one for now. See if inspiration strikes while doing the tidying up.

Debian NSLU2 Stopped Working

My slug, NSLU2, stopped working. The power went off and it didn't come back on after booting. It just sat there with the ready light on yellow and the ethernet on green, but not showing anything on the disk 1 light. I couldn't ssh to it or ping it. Google led me to the NSLU2-linux-debian-readme page. This led me to suspect something wrong during booting. I turned off the slug and attached the USB drive to my debian PC. In the procees the entire USB hub stopped working. If I took the USB hard drive out the USB hub started working again. So I rebooted into windows, put the USB drive in and got an instant blue screen of death. Not good. Last attempt I plugged the LaCie USB drive into my laptop. The laptop didn't die, but windows said "Please insert disk" when I tried to browse to it. I'm thinking it is dead. Looks like I need to be buying a new USB hard drive and re-installing debian on the slug. If anyone has a better idea please leave a comment!

Using my Slug as a Mercurial Repos

I've bought a slug inspired by the now defunct Linux Reality podcast. It had been hanging around for a while but now I've found something worthwhile to use it for. I've been using Mercurial for distributed version control and the slug makes a great central repos. I've got Debian etch running on the slug and mercurial was a simple apt-get away (actually I use aptitude to manage the packages). With mercurial installed and a little setting up of ssh keys I'm good to go. I simply have a single mercurial user on the slug and make sure for any files that I edit I first pull from the mercurial user and when done push back. I can now edit the same files from work, various computers at home and at the inlaws and keep the whole thing under control. Now, if only I could get a symbian S60 version of mercurial going...

Age of Empires

My oldest son loves Age of Empires II, so I decided to see what fun we could have hacking with the game.

Before kids I spent too much time playing Age of Empires II. Since kids I've been a recovering adict, keeping well away from temptation as I feared that one hit would lead me down a slippery slope to the AOE monster eating my free/sleeping time. Recently however my oldest son has started playing AoE2 himself, influenced by his mother I should explain. He started out on the scenario levels becoming a great fan of Gengis Khan, Joan of Arc and friends. It was his idea to start hacking with AoE2. We went on a visit to Warwick castle and the next day he suggested that it would be great if we could play a Warwick castle game on AoE2. A little playing with the scenario builder and we had a passable map of Warwick castle with the forces of Ricard Earl of Warwick lined up against the Duke of Hastings and Edward 4th. My son was in charge of deciding the sizes and composition of the various forces and, being only five, he made quite sure they were heavily biased in the human player's favour. We got this set up and ran the game. At first we couldn't get the two sides to fight each other. Then we found the dipolomacy settings and with the help of drawing up the grid of who was with who, got the correct forces to engage.

My son seemed quite happy with the set up we had. He'd get his huge band of troops, march up on the hapless enemy and win decisively. I was disappointed with the way that the computer controlled forces did little to defend themselves. They just stood about and waited for the enevitable anihilation. A little digging and I found that AoE2 has a scriptable AI language and there are lots of people writing AoE2 scripts at www.aiscripters.com. So now I have my next hacking mission: learn the AoE2 scripting language and start coding some things in it. Meanwhile, my son has this idea for a "build the Great Wall of China" scenario.
