Recently switched back to openSUSE after a brief stint with Ubuntu. I guess you need to try other things out to know how good you have it, eh? Anyway, I’m playing with Leiningen and Quil, but for some reason or other, I could not get Leiningen to self-install, because of an exception:
java.security.KeyStoreException: problem accessing trust storejava.io.IOException: Invalid keystore format
It turns out that the java keystore is somehow corrupt on OpenJDK / openSUSE 12.3. Not sure who’s at fault, but here’s how to fix it.
In a previous blog entry I described setting up a caching-only DNS server to speed up hostname resolution on Debian systems. I’ve recently been playing with Ubuntu and noticed that this hack is not working.
I think I can finally put this old walnut to bed, having just updated it with some observations made by guru’s of Stack Overflow. Hooray, only took me four years 😛
This is common knowledge, yet strangely every time I rebuild my work PC (which is too often! Gah!) I try and Google the location of Registry keys and folders and always, always get a bum-steer. So here, have another (bum-steer?) version of this hack on the Net.
This post is also available at my personal web site: http://milosophical.me/blog/2012/02/13/install-emacs24-snapshot-on-debian-ubuntu-and-windows-7.html
I just can’t wait for Emacs24 to be released! (I know, it’s in beta and it’ll be officially released Real Soon Now, but my catalyst is Technomancy’s ESK2 which is such an improvement over ESK1, and it needs Emacs 24).
In my last post I had steps to build emacs from source-code. This is worth following for hacker cred, but it soon gets tedious if you have a lot of systems to put emacs on. As pointed out by a few readers, there are some snapshot builds available for different platforms. This post lists steps for installing the pre-built snapshots, for the three operating systems that I use.
