It’s a binding together of several popular Lisp packages for OS X, including: Aquamacs, SBCL and SLIME. Once downloaded, you’ll have a single application bundle which you can double-click — and find yourself in a fully configured Common Lisp REPL. It’s ideal for OS X users who want to try out Lisp with a minimum of hassle.
… There is a GnuPG signature for this file in the same directory; append .asc to the above filename to download it.
I’d been avoiding adding full Unicode support to Ledger for some time, since both times I tried it ended up in a veritable spaghetti of changes throughout the code, which it seemed would take forever to “prove”.
…If a user has Cyrillic characters in their data file, and Ledger leaves its encoding alone, then when those same bytes are printed out the user will see exactly what they input.
…And without knowing the length, it’s impossible to get columns to line up, or to know exactly where a string can be cut in two without breaking a multibyte UTF8 character apart.
Anyway, I discovered a cheap solution today which did the job: Convert strings from UTF8 to UTF32 only when individual character lengths matter, and convert them back after that work is done.
The other day I finally implemented a feature in Ledger which I’d avoided doing for a full half-year. The reason? Every time I thought about it, my brain kept shutting down. It seems my brain doesn’t care for math much, or for mathy problems, so it always seemed as if something better needed doing…
The blog has now fully moved over to Movable Type, including all past articles and their comments. It took a bit of Perl, Python and mucking with SQL, but now the transfer is complete.
After tracking it down on a public domain mirror, and installing an emulator on my MacBook Pro, I was able to download and run the first full computer program I ever wrote: “Sector Inspector” for the Apple //e.
I wrote this program in 1989, and took eleven months to write it (seven to code, four to debug). At the time, it was one of the more complete disk editing utilities I’d seen.
All of this works just great for Windows machines on the network, where everyone can use names like “host” to refer to each other’s machines.
… On the Windows Domain Controller, go to the admin page for “Active Directory Users and Computers”.
… This step is for CentOS: For every Linux box, edit the file /etc/sysconfig/networking/devices/ifcfg-eth0 (or whichever interface faces your local network).
… Voila, your Windows server should now see the Linux box’s name just like everyone else on the network.
