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:

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. … Continue Reading

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

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

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.

Yesterday I added myself to github.com community:

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

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

1. to switch to something.blogspot.com and lose all my search engines entrances?
2. to switch to Blogger’s “custom domain” (probably shaos.net) and again lose all my search engines entrances?
3. 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 … Continue Reading
