I am looking for a good system to document my program.

The program is written in VALA. So I used valadoc to docuemnt that actual code. But it would be nice if there was a ready to use system (online or not) to create things like simple uml diagrams,  explenations with example code, class and inheritance diagrams, etc.

Anything like this exists?

Thanks,

A movie says more then 1000 words:

stuffkeeper-generic-input2.ogv

This is a nice little board that can run off a simple  +12 & +5 Volt power supply.   It can run fan-less (later more on that) and should be fast enough to run MPD + a stream output and some other software.

So below a quick description about setting it up as MPD + other stuff server:

Goal of the box

The main purpose of the box is to run MPD, allow me to stream (via ssh forward) music from university.

For the rest I have the following tasks planned:

• Simple web interface for MPD.
• IR Remote control.
• IR Control off my stereo. (turn off/on etc)
• Turn light on off (it has some General Purpose IO (GPIO) I might be able to abuse for this)

The hardware

A quick overview of the system:

• CPU:  Celeron 400Mhz
• Memory: 512 MB
• Harddisk:  1GB CF Card. (contains only /boot + grub)
• USB: 2x usb 1.0  2x usb 2.0
• Network: 2x 100mbit
• The root system is placed on NFS, mostly because I want to keep the box as quiet as possible and I did not want to spend lot of money on a large CF card.
• OS: Debian sQueeze
• Soundcard: (temporary) Behringer  UCA202

First thing I did was ditch the power supply it came with, this was a switched 100W  ATX supply making a horrible beeping noise (so this was a no go). Remove the 6000 RPM fan blower.  To make long story short, I removed everything beside the board.

The board can be powered using a normal molex connector, so after digging up an old external CD casing I had a nice fanless, noisless power supply.

edit: This one broke after 2 weeks, so now it is powered for the time being by an atx PSU..  Needs fixing.

So after setting up the Debian on the NFS root and moving /boot and grub to the CF card.

Doing some test shows that the CPU stays a nice 30 degrees, the chipset is another story (it almost feels like an early atom system), this one goes up to 60 degrees.

I added a nice large 12x12cm fan that keeps the chipset a nice 25 degrees. It does however make more noise then the 13 dB they mention (it kinda runs unstable) But doable.

At the moment everything runs fine. Need to add a case later.

Software

• OS: Debian squeeze
• kernel: 2.6.32
• mpd: 0.15.9
• lighttpd

Problem:

Update-grub cannot wrap his head around root being on nfs. So it cannot correctly install the package. So every time I install something, it tries to finish configuring grup-pc and I get a fail, still need to fix this. (Fixed this by modifying the postinst script).

Case

I am not really one to care for casings and stuff like that. So it sits kinda bare next to my stereo at the moment:

Monitor

Thinking about getting a samsung U70 as a small status monitor. These are to expensive for now. So I might just use a 4×16 character display for the time being.

Infrared

Light control

The general IO proved to be more tricky then I thought, to read/write to it I needed to send the bios interrupts that would then read/set the value. So this required writing a kernel driver. To much work for the time being.

I solved it by letting a small atmel AVR control a few relays, a display and some other hardware and be controlled by the machine via a serial interface.  (The atmel acts as temperature sensor, 4 channel light control, clock, 64 item timer (programmable time+weekday))

I will add a lot of stuff later.

But just now I noticed they added (or might have been there in previous?) a 500 song limit on adding songs to playlist. When searching on the forum, this was done for performance issues.  People to often found themself adding lot of songs to the playlist, causing the server to lock up for 10 minutes..

In the world of today, where your phone is faster then a pc from 7 years ago, is this possible? The server _has_ near nothing todo, beside scanning the music and serving it. (I don’t use transcoding and all the other stuff).

Sorry, but a machine with a 1.5Ghz Via Esther and 1 gig of ram should handle a 10000 playlist easily. It should handle 100.000 songs easily.  Why can’t a commercial company that has been at it for many many years (first slimdevices, now logitech) get it right.  The web interface is still terrible slow, near useless, the iphone application often stalls too on searches (happens server side I guess). Only the interface on the squeezebox itself is doable, if the playlist is small.

I raised the limit, and indeed try to add my full collection. I am still waiting for the cpu usage to drop and the center to become available again.  At logitech: Hire a decent C programmer, dump the perl core and get some performance going. 100000 songs in a playlist should never ever be a problem, esp. if you use a full fledged database as backend.

I don’t get this. I really really don’t.

p.s.  Tested mpd, it runs fine with all my songs added to the playlist.
