2 programmers wanted

I am looking for at least 2 programmers to join a youngish company developing real-time systems using a combination of R-Pis and Windows servers. The business is based in NW Hampshire, UK, fairly rural but would suit anyone who wanted to commute from Newbury, Southampton or Salisbury. Would suit a r...

Re: Dyalog APL available for the Pi

Nice implementation and it runs very well. APL is a very expressive language based on Iversen notation (developed by Ken Iversen who implemented the first version of APL over 40 years ago). It is implemented as an interpreter oerating in an interactive environment, allowing rapid development resulti...

Re: Which distro? (live music graphic effects)

MIDI support in debian is pretty good, but it comes in 2 flavours: ALSA, which is the latest version and supports most USB<=>MIDI adapters, and the earlier OSS which doesn't support so much but has a more powerful collection of MIDI utilities. To try out MIDI support install the ALSA package and try...

Re: MIDI keyboards?

I just had someone ask me (or, more accurately, the Raspberry Pi Twitter account) how to hook up a MIDI keyboard - and although usually pretty glib, I wasn't able to help. Anyone had a go yet? Not quite the same thing, but I hooked up my R-Pi to a Roland XV-3080 synth module through a Roland UA-100...

Re: RPi Power Supply

It was a mistake to fit a micro-USB connector for power. I think the logic was that most kids have a modern cell phone so they could use the charger. As far as I can tell Micro-USB is exclusively for cell phones. It would have been much more sensible to fit a 2.5mm power socket. That would have giv...

Re: Maybe time for an RMA ?

I was having similar problems and tried a variety of adapters and the voltage measurements across TP1/TP2 were around the 4.6V mark even with all t...

Could be a power problem. LXDE consumes more power than just running the console and that could be pushing you into dangerous territory.

If you have the right hardware/software, it is quite straightforward to use the supplied disk formatting utilities, but out of the 30 Windows machines available to me only1 had the required SD cardreader/Win7/Vista combination required.

Re: Cheapish HDMI portable display


You can use your TV as monitor


Maybe I would if I had a TV, but there isn't one in this house, with or without HDMI, and all of the monitors are VGA. Not complaining, but just pointing out that the "total cost of ownership" is far higher than the headline figure.

@bob_binz: Dixons / PC World Jan Sale, end of line, ex-display model. Seems to still be a current model at Samsung, so I was pleasantly surprised and have a hankering suspicion that it might have been a mistake by Dixons, but I'm not complaining.
