Re: We're looking at introducing more swag - what would you like to see?

T shirts less garish, with logo not central but to the left; possibly more likely to appeal to the less extrovert, which to be honest is probably more the market here!

Re: Is it possible to read the value of a UK dimmer switch with Raspberry Pi?

Sounds to me like the OP is asking whether a dimmer switch can be used as/like a rotary encoder; not necessarily anything to do with mains voltages (I sure hope)

It kills mosquitoes by the thousands every night. They get attracted to heat and carbon dioxide. http://www.svtstatic....

You didn't say which you've got. I2S needs some work to get going.

If it's a different board, then you may need to use other instructions!

It's basically the bits that other manufactures also have - but shove into firmware areas of their hardware so it's not so obvious. It's nothing to worry about.

Re: Using RPI for searching in huge .txt

grep's fine for easily-defined problems like a phone directory, but big text searches benefit from an engine like Lucene . It brings typo-tolerant searches, ranking, search ranges, searching while updating, … none of which grep does well, if even at all. Ahh - but Lucene doesn't produce nice graphs...

If you know that the character strings making up the codes cannot appear anywhere else in the file you can do this: grep 10457 filename or to look for a list of known values: grep -E "10457|22222|33333" filename However if those codes could exist elsewhere in the lines where you don't want to look (...

I'd suspect grep will be quickest, and can use perl regular expression syntax to do the searches. What are the matching search criteria?

Re: Using RPI for searching in huge .txt

It depends what you want to get out of the file.

To find lines matching some string, I'd use "grep" from a console:

grep "what you want to find" filename

For complex extraction I'd probably use perl as it's very fast.
