Building GHC6 on Arm

I got talked into darcs and now want to be able to check out my patches on

my nslu2. Unfortunately darcs requires ghc, and ghc requires itself to compile. This leads us to the joy of making a new port.

http://www.haskell.org/ghc/docs/latest/html/building/sec-porting-ghc.html

I started with the above link and tried to get it to work. So far, the files they tell you to copy includes/(ghcautoconf.h DeriviedConstants.h GHCConstants.h) are not created by the configure step so you need to run make boot in the ghc directory on the target.

Then after copying them over make them read only, as my touches weren't enough to prevent their makefiles from trying to rebuild those files.

i managed to get it to start building, but it died trying to make the compiler with a bunch of cast errors.

Asterisk Frustration

I've been trying to setup a VoIP system at home ('cause) and can call

my cordless phone (plugged into a SPA-3000) from a IP Phone (grandstream gxp-2000)

That's all good and works fine. I then decided to go further and plug the SPA-3000's FXO(?) port into my vonage ATA. I can get it to make outgoing calls, and sometimes even incoming calls.

I can't get authentication to work for outgoing, and I can't get caller id to work for incoming.

This thread was rather helpfull on getting the calls working.

..:

[spa_outbound] type=peer secret=<SECRET> port=5061 host=dynamic canreinvite=no nat=no qualify=yes dtmfmod=rfc2833 context=incoming-vonage

is my current outgoing config.

On the SPA I have the PSTN line registering seperately from the ATA line.

If I want to get things to autoforward to the server I need to set PSTN Ring Thru Line 1 to off and to set a dial plan to SO< s:@server.host:5060 > (And of course tell the PSTN which dial plan to use.)

If I set the CID on, asterisk 1.2.1 gets very confused about the source SIP address and chokes. I tried setting things to insecure=very but to no avail.

I'm thinking I might try openser, as its more sip orientated. (Though there documentation is quite sparse).

I found some documentation on the SPA-3000

Stocastic Grammers

Eric showed up to advertise his stochastic grammer techonology. http://computableplant.ics.uci.edu/papers/StochProcSemanticsTR.pdf

It appears to be a production rule -> result with a probablity Of course the various components can be mutualy dependent on various state parameters.

The question is can this be used for biological network evolution?

E.g. simplified cell cycle?

Also Eric's papers are linked from http://www.ics.uci.edu/~emj/

Digging through UCSC

I've been digging through ~kent/src looking to see how the UCSC browser works, so we can write our own API for grabbing data out of it.

Table descriptions from from .as files (autoSql) and are loaded into tableDescriptions.

There's grp table which lists the defined groups.

The map between tables and which group they belong to appears to come from *.ra files. I haven't found a place in the database where they're stored yet.

System Message: WARNING/2 (<string>, line 10); backlink

Inline emphasis start-string without end-string.

Brians Repeats

We're trying to determine if there are repeats near genomic probems.

The first pass file had a large number of repeats in it.

high_genomic_signal_fewer_repeats.txt had those stripped out.

I created a fasta file with the following python code

data = [ x.strip().split('\t') for x in open('high_genomic_signal_fewer_repeats.txt','r')]
open('high_genomic_signal_fewer_repeats.fa','w').writelines([ ">%s|%s\n%s\n" % (x[2],x[0],x[3]) for x in data])

ok yeah I shouldn't do that in so few lines.

Hopefully the following

blastall -p blastn -e 0.000001 -d mouse_34.0.fa -i high_genomic_signal_fewer_repeats.fa -m 7 | tee high_genomic_signal_fewer_repeats.blast.xml

command will generate a new, smaller xml results file.
