Personal stuff
Hello, my name is Lev Walkin.
My interests include computer programming,
software development, writing in artificial languages, entering codes
into digital machines, and similar exciting types of leisure.
I also like playing badminton,
listening to music (Pat Metheny, George Benson, Keith Jarrett, Pink Floyd),
and taking pictures of various fine little things
(or not so little; see the Photography section). I have no TV at home.
My dear wife, Olga Bobrova, has given birth to a cute little boy on December, 19, 2006.

Free Software
Here are the several open source projects I'm working on now.
- asn1c-0.9.21 – The ASN.1 to C compiler. Also use Online version.
- ipcad-3.7 – A versatile IP traffic collector (Supported capture methods: BPF, libpcap, tee, divert, ULOG, IPQ; Supported export methods: RSH, NetFlow, file dump).
- libstrfunc-8.2 – A collection of text processing functions, primarily aimed at CGI developers (Includes support for CGI forms handling (GET/POST), base64, MIME, date/time conversion routines, textual template formatting et cetera). Has the fastest strtotime conversion routine around.
- ... and more C sources.
One of my pet web projects is the online ASN.1 compiler page. It is home to a tool where Texas cellular providers convert their multi-megabyte CDR data (TAP3) into XML, since most commercial tools are not up to challenge. (I never disclose their data. No. Don't ask. No, I don't know his number.)
Once upon a time (1997) a few years have been spent developing the following Windows beast:
- The Network Emulator 3.0 – A system for visual modelling of the TCP/IP networks.
It allows the user to visually create a mesh of hosts interconnected by various network media (Ethernet, serial, etc).
These virtual hosts run virtual programs, like "telnet", "ping",
"traceroute" and "gated", written using finite state automata; the system visually models the TCP/IP stack behavior.
The emulator supports the IP, ICMP, UDP, TCP and even BGP protocols.
This project is listed here largely for sentimental reasons.
