x11grab in ffmpeg svn

Edouard Gomez did a great job on pushing my x11grab patch into ffmpeg. He smoothed all rough edges ranging from my blunt ignorance of the ffmpeg coding guidelines to obvious hacks without any remorse.

The patch series hit ffmpeg svn on 20061212. Get it from here. You have to run configure with --enable-gpl to get the GPL-ed x11grab implementation. To actually start grabbing, run

ffmpeg -vcodec mpeg4 -qscale 2 -r 10 -vd x11:0+0,0 -s 1280x1024 whatever.avi
You should replace 1280x1024 by your actual screen resolution.

Liskell standalone

Some time has passed since I last blogged about Liskell. It is not dead nor have I changed my mind that Haskell needs a proper meta-programming facility not to mention a better syntax.Liskell was a branch of GHC once. Now it sits on top of the GHC API, or I should rather say sneaks behind its back as it creates its own API as the original one is not suitable for the stunts I'm interested in. If Liskell sticks with GHC as its soil, I will definitely send patches upstream to refine the GHC API in the areas where it needs more flexibility for Liskell. However for the moment, my main target was to get something out that compiles with a stable version of GHC.You can grab it with the usual: darcs get http://code.haskell.org/liskell/ This version has been tested with ghc 6.10.1 and should install like: ./Setup.lhs configure ./Setup.lhs build ./Setup.lhs install cd LskPrelude make install-inplace Optionally you can run make tests in the testsuite subdirectory. Thanks to community.haskell…

Is the new post-money SAFE mathematically sound?

Y-Combinator published a new set of documents for their SAFE, short for "Simple Agreement for Future Equity". The new version takes the document from a pre-money investment to a post-money investment. But for those of you that know neither versions, a SAFE is a legal document signed by the SAFE investor and a startup, so that the startup gets cash to build their product and the investor gets equity in the company. How much equity the SAFE investor gets is not spelled out in numbers but in the form of a set of equations that should compute this number at a later stage. "Later" usually means at the next funding round called Series A, where a larger investor injects more cash into an already working prototype of the product. At the point of Series A, it is much more clear on how the product performs and whether there is a market. The Series A investment usually happens a year after the SAFE investment. The assumption here is that it is fair to both the startup and th…

XMonad GridSelect

Personally, I not just need a window manager, I need a focus manager. I tend to think of windows as TODO items, and as there are many TODOs in life there are many windows on my workspaces. Usually a fraction of that can't be closed or worked on immediately, so they linger around on my desktop, cluttering my workspace.I used to use the Tabbed layout. But Tabbed isn't the answer when you are a guy who reports bugs such as "XMonad 0.6 with Tabbed dies when firefox-session-restore slams 40 windows at once on the desktop". In other words, I use a lot of windows. The workspaces concept isn't particularly useful to me either. My mind just doesn't work with mental boxes. So the result is, that I have too few workspaces with too much windows on them, so that Tabbed has trouble displaying useful window titles, and navigating through them is slow and cumbersome (mostly because tab switching generates a lot of useless X Expose events).GridSelect is my answer to that. It…
