As of today the PASTA project has issued an official press release about our new EnCore microprocessor.

Press Release: Gadgets could go greener with high-speed computer chip

I have just finished the facelift of our CArD – Compiler and Architecture Design Group website. The people page gives a good overview about our members and we finally have a news section as well.

From today on we have a wikipedia page for the EnCore processor.

Also if you search for ‘pasta project’ on video.google.com we are one of the top hits. We also do very well on traditional search engines like google, yahoo, and bing – searching for ‘pasta project’ reveals us at the very top most of the time.

I have been working on a video that portrays what our PASTA research group does. Have fun watching it and remember that none of us are professional camera men, actors, or video editors - so it is a bit shaky but hopefully still informative and fun.

This has bugged me for a while when useing TextMates ‘Filter Through Command…’ to replace all newlines in a selection. Somehow my mind always wants to use sed to do this although there are simpler ways to do it.

The following works with GNU sed but not with BSD sed on my Mac (although it should work given the documentation in the man page):

sed -n ':a;N;$!ba;s/\n//g;p' < infile

What this does is the following:

• :a put label at the first position
• N Append the next line of input to the pattern space
• $!ba branch to label a, the ! tells it to apply the command to a non-selected pattern space and the $ addresses the last line of input
• s/\n//g substitutes a newline with a space
• p writes pattern space to standard output

If you can make this work with BSD sed please let me know.

Our PASTA (Processor Automated Synthesis by iTerative Analysis Project) research group has a new website. The content is still quite incomplete but over the next few weeks we shall bring it all into shape. So stay tuned….

Searching in large projects (i.e. gcc repository) can be painfully slow with TextMate. If you encounter this problem have a look at the Ack TextMate Bunlde.

Get the standalone version of ack from here.

A nice article by Oleg Kiselyov about Existential Datatypes. Enjoy!

If you are functional programmer you surely have used foldr or foldl before. By accident I found out that Oliver Steele registered the following domains:

• http://foldl.com/
• http://foldr.com/
