KillmailUnfucker

CCP, the developer of Eve Online, has a nice way of showing their intelligence. They recently added (proper) localization support to their game, which is nice for our russian and other non-latin friends. As a side-effect however they included localization of killmails, which horribly breaks importing them to any killboard. Many killboards have been updated (read: work around ccp's fail), but you're the one stuck posting to a killboard that hasn't been updated.

That's where KillmailUnfucker comes to help. It monitors your clipboard for any killmails you may have copied from the Eve Online combat log. When it detects you copied a killmail that is malformed, it fixes it and updates the clipboard.

Taking down the old site

Recently I've decided to stop hosting the old netripper.nl site. It contained mainly old stuff. The only new stuff on that site was new content added by spam bots which I had to delete all the time. I figured a blog is good enough for me, even though I don't blog often.

Goodbye dear old site. You served me well. It's time to rest.

TS2Overlay - Teamspeak 2 Overlay

I'm playing a lot of EVE Online recently and am currently in an alliance that uses the older Teamspeak 2 client to talk with eachother. As there don't seem to be any Teamspeak 2 overlay applications that work for Windows 7, I've created one of my own.

Head over to the TS2Overlay page on my blog for the details. Comments go there as well.

Overclocking the MSM7200 / MSM7201a

After writing an overclocking tool for the HTC HD2 (Leo), I had a request from someone challenging me to overclock the HTC Touch Pro 2 (Rhodium). As I still have an HTC Touch Pro (Raphael) myself, with the same processor in it, I decided to give it a go. I quickly learned someone (bzo) managed to overclock the same processor on Linux already while working on their Android port to the MSM7k device series. Being able to use that code as some sort of limited documentation I've also written an overclock tool for a number of HTC MSM7k based devices, such as the Raphael, Rhodium, Diamond, Topaz, Blackstone and Whitestone. It's not working perfectly yet, though. For now it's only possible to overclock on AC power, except for the Rhodium which seems to overclock on battery as well. Read all about it in the thread on XDA.

Btw, the MSM7201a is a 528MHz processor. Some have reported to be able to clock it at 787MHz before it hangs. That's a pretty insane overclock if you tell me. For me it's stable at 710MHz. I can push it to 750MHz, but it'll lock up as soon as I do something heavier on the device, like watching a movie.

CPU speed control for the HD2, including overclock!

Today I've released a new app for the HD2 to control the CPU speed of the device. You can scale the speed anywhere between 128MHz and 998MHz and lock it by disabling the autoscaling feature that HTC put in. Having the CPU at 998MHz all the time (as opposed to the 768MHz default idle speed), you don't notice the battery increase. I didn't at least.

I've also ported some of the code from the Nexus One linux kernel to allow overclocking. Unfortunately it's not possible (or I haven't found a way yet) to increase core voltage, so you can't overclock too far. You should be fine overclocking to 1.1ghz. Overclocking to 1.2ghz is tricky already and I've never been able to clock it at 1.228ghz or higher without it instantly locking up.

Also one other major limitation is that overclocking currently only works on AC power, as on battery the phone somehow enforces the cpu speed at 998mhz (or more specifically, last used performance level) every 500 milliseconds. I'm still trying to figure out how to fix this. :-)

Irssi tips for newbies

A colleague of mine recently installed irssi and I thought it'd be nice to give him some hints on scripts and some handy commands etc. After writing that up I thought it couldn't hurt sharing it with the world as well. Even though this is written for irssi newbies, it's not written for linux newbies :-)

1. Install scriptassist

Scriptassist is a script that will make your life within irssi a bit easier. It will help you install new scripts and add them to autorun.

# mkdir ~/.irssi/scripts/autorun
# cd ~/.irssi/scripts

# wget http://scripts.irssi.org/scripts/scriptassist.pl

# cd autorun

# ln -s ../scriptassist.pl

In irssi just type: /script load scriptassist
It may fail to load due to missing perl dependencies. Resolve these by installing the missing dependencies and try again.
When it loads correctly, you'll get info on how to use it with: /scriptassist help

2. Some nice scripts

Here's a few scripts that I'm using within irssi myself.

• autowhois: when someone queries you, it does a whois and displays it in the query.
• autocycle: autorejoin after kick (not always appreciated in all channels and can result in ban)
• binary: encode/decode for fun (01101000 01100101 01101100 01101100 01101111 00100000 01110111 01101111 01110010 01101100 01100100)
• kenny: same (mfpmpppmfpmfppf fppppfpffpmfmpm)
• nickcolor: gives each nick a seperate color (edit nickcolor.pl --> "my @colors = qw/3 7 9 10 11 12 13/;" for my recommended color set to prevent your eyes from pinching)
• queryresume: gives the last 10 lines of the previous time you had a query with that person
• splitlong: if your text doesn't fit on one line, it splits it over multiple ("/set splitlong_max_length 460" to be on the safe side)

These are just some suggestions. You can find all irssi scripts on their scripts site.

3. Some handy commands

• Make irssi remember what channel is in what window: /layout save
• Current people in channel: /n (or /names)
• Current topic: /t
• Close window (& part if chan): /wc (/window close)
• Search through current window: /last mysearch
• Scroll up 10 lines via command: /sb goto -10
• Scroll back all the way down: /sb end

4. Aliases that can be useful

Some aliases just make life easier. Especially when working on a mobile device in which you cannot use the alt key to change channels :-)

/alias 1 /window goto 1

/alias 2 /window goto 2

/alias 3 /window goto 3

/alias 4 /window goto 4

/alias 5 /window goto 5

/alias 6 /window goto 6

/alias 7 /window goto 7

/alias 8 /window goto 8

/alias 9 /window goto 9

/alias 10 /window goto 10

/alias 11 /window goto 11

/alias 12 /window goto 12

/alias 13 /window goto 13

/alias 14 /window goto 14

/alias 15 /window goto 15

/alias 16 /window goto 16

/alias 17 /window goto 17

/alias 18 /window goto 18

/alias 19 /window goto 19

/alias 20 /window goto 20

/alias c /window close

/alias dns /exec host $-
/alias figlet /exec -o figlet -s $-

5. Configuration settings

• Logging (only logs queries, add "pub" after "msgs" seperated by a space to also log channels)
  /set autolog ON
  /set autolog_level msgs
  /set autolog_path ~/irclogs/$tag/$0.log
• Away log
  /set awaylog_colors ON
  /set awaylog_level msgs hilight
  /set awaylog_file ~/.irssi/away.log

Hope this info is useful to someone! :-)

Linux on HD2: IRQ problem solved!

Just an update. Last few weeks we've been working on something we named "the irq problem". After registering some interrupts, whenever the first one fired, it would cause an infinite amount of "bad IRQs". Finally after a bit of coincidence that we read along some of the problems randomblame was having, we saw some interesting code in the entry-macro.S file, patched by vladone. This was the solution to the irq problem.

It's typical. You do really a lot of research on something, and it turns out to be something so small (only three lines of assembly code). As you can see on the git repo, getting rid of this blocking issues allows us to finally do some other work.
