Recently I released version 0.5 of my fork of pre-existed Hope interpreter (classical functional programming language) named “Hopeless”:

  • added ‘\r’ to function “isspace” in ctype.hop
  • fixed function “dir” in system_win.hop
  • path to libraries changed to /usr/local/share/hopeless
  • created man file hopeless.1 (modified hope.1)
  • fixed “make install” for Hopeless
  • new library lib/db_sqlite.hop (database support with sqlite3)
  • added functions “del” and “write_to” to lib/system.hop
  • check for ‘\n’ and ‘\r’ before run commands (“!…”)
  • defined constant “stdin” instead of functions “getc” and “gets” (lib/system.hop)
  • modified test _input.hop

Source code: hopeless-v0.5.tar.bz2 (100K)
For more info see www.hopelog.com where you can find all previous versions of Hopeless plus Win32 binaries.

My PowerMac G4 400MHz with Debian GNU/Linux 4.1 (that works as my home server and internet gateway since last summer) just got 157 days uptime (without reboots since January 28th 2009) before yesterday strange hanging that was resolved by manual rebooting…

P.S. Electric power stability is provided by APC Back-UPS ES 750 that may keep the server working without electricity for more than 40 minutes!

P.P.S. Last “north-easter” poweroutage proved that my system’s up time without electricity is 75 minutes!!!

Again I tested new hardware using my memcpy benchmark – now for my 1st desktop on Intel Core 2 Duo 2.6 GHz and my 2nd desktop on PowerPC G4 450 MHz (black G4 Cube). Here you can see not-aligned (nal) and aligned (al) results and also “vectorized” results (G4-450v-nal and G4-450v-al) where memcpy was AltiVec optimized version from libfreevec v1.0.4.P.S. If you want optimized AltiVec versions of such functions as bmove512, memccpy, memchr, memcmp, … Continue Reading

I decided to use G4 Cube as my second desktop computer. But my first desktop PC is black. So I bought black enamel spray for a reason to paint Cube to black color. The subject to turn black is internal metallic case:Now I have stylish black colored G4 Cube with Debian GNU/Linux 5.0 “Lenny” on board :) P.S. Lenny believes that X.org became smart enough to … Continue Reading

OK, I got Debian GNU/Linux on my desktop Power Macintosh G3 “Beige” BUT, to do this I bought MacOS 9 CD for 20 dollars on ebay:Because I broke pre-installed MacOS by trying to install Debian on this “OldWorld” mac (see here). So, after installing MacOS 9 back I again tried to install Debian (using BootX 1.2.2 from MacOS). After a number of tries of reinstallation of both I realized that MacOS 9 and Debian CAN’T live on the same … Continue Reading

Finally I did it – I bought G4 Cube for myself! $250 (plus shipping) for PowerPC G4 450 MHz system is a little bit expensive, but it’s CUBE:It even has “cracks” (as probably all G4 cubes ;) Of course I put Debian GNU/Linux on it and removed MacOS 9.2 that was preinstalled there.One strange (for me) thing about G4 Cube is its power … Continue Reading
