Now I’m thinking about building binary circuits based on 74F00:

Explanation of idea about ternary hardware based on DG403 switches and also attempt to apply the same approach to 4-value logic:

Ternary Hardware – CMOS switches

DG403: one chip with resistors

Here I use undocumented feature of DG403 when normally closed switch opened by voltage lower than required to close another (normally opened) switch. Variable resistor is used to move that “both-opened” window to ternary “0″ zone (up from -3.0V…-0.8V to cover 0V).

DG403: two chips - no more components

Second scheme is more “correct” (nothing from undocumented features were used).

P.S. Ternary selector may be used as ternary inverter when RP=-5V, RO=0V, RN=+5V. See more details on www.ternary.info

Another portion – now about extension of 3niti alpha simu1 board:

Way to convert Morse code to balanced ternary code and back:

Hopeless v0.5

Shaos — Sun, 23 May 2010 16:22:09 +0000

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.

Bye Bye Google Blogger

Shaos — Wed, 03 Feb 2010 05:33:52 +0000

I’m on WordPress now and almost all links are saved

Import from Blogger was perfect!

Permalinks with custom structure /%year%/%monthnum%/%postname%.html correctly replicate Blogger’s URLs

I installed plugin “Smart 404″ to handle broken URLs to labels – it’s working fine

But now archive URLs are different and RSS feed URLs are different – it is minor problem

No more FTP in Blogger

Shaos — Wed, 03 Feb 2010 01:01:00 +0000

Google has decided to drop FTP support in Blogger since March this year. So what should I do?

to switch to something.blogspot.com and lose all my search engines entrances?
to switch to Blogger’s “custom domain” (probably shaos.net) and again lose all my search engines entrances?
to say good-bye to Google Blogger and convert my blog to something else in the same place (shaos.net/blog) and save all my search engines entrances?

P.S. I’m glad to be part of “unique” 1/200 subset of Blogger users who was using FTP, but it’s just too sad…

P.P.S. It looks like more political than technical decision – they simply want to have power to shut down any blog entirely in 1 sec…
