My friend is looking for Information Security related job in the Toronto area.
It's a resume in pdf

"GnomeMeeting VTA"
I collected and analysed additional data about Cisco VTA and 'CAST' (as ethereal dissect it) protocol.

What is 'Advantage' (as the 'A' in a 'CVTA') means?

    If one has already installed Cisco IP telephony, then it can be easy and 'chiply' extended with videotelephony capabilities. The extension includes slightly modified Logitech webcam (cisco logo, different usb id, possibly some other code in the cam firmware) and some software. This 'bundle' is about twice+ in price of the same regular Logitech webcam. Software is win32-only.
    To install you need attach webcam to usb-port on your computer and switch on video for your IP-phone (7940 and more powerfull models) in the CCM (CallManager -- Cisco IP PBX) configuration. When somebody with videophone capabilities calls you by IP phone, CVTA-client brings up and setup videocall. So you are looking on screen and speak/listen with phone handset/handsfree.

Technical side.

    CVTA client uses CDP (cisco discovery protocol) to learn IP-address of IP phone your computer connected to. CVTA client setups TCP connection to phone and uses 'CAST' to exchange information about line/call state. As part of this information CVTA receives IP-address of calling party and setups videocall (H.323, RTCP + RTP).

The idea is to add something (support of CAST?) to GnomeMeeting and replace CVTA with GM. I'm trying to read some unix network programming books at present ;-)


  • "GM advantage" would be able to work with about any webcam
  • "GM advantage" would be able to work on OSes supported by GM

    So there is some 'market' to share ;-) Additionaly such a plug-in (which extract info about calling party phone number/name) can be used as the base for CTI extensions (for example, bring up an evolution window with last e-mail received/sent to calling person).

    About a month after examination I received my JNCIS-M certificate.

    Nortel presented me with usb-flash drive (256Mb only, while there is 2Gb models -- 'The Canadian Greeders' Team ;-)...

    CISSP (examination day)
    Have no idea about results. I answered 250 questions in about 3 hours and spent about 40 minutes for transfering the answers to an answer sheet (this is the most annoying part of exam). Proctors claimed that the results will be available at 2 weeks. It was funny to meet _two_ friends there. One of them is in the proctor position ;-) And another one is my ex-collegue from DataForce, also she is CCIE Security.

    Changes of some region telephony codes in RU and modification of call routing temporary droped my ability to call to my mother. VoIP gateway insert city-code second time collect some digits from the phone number part and make call to somebody other.

    My father said me by phone that the strong wind hurled a big trash container into the window of some old women at 2nd floor (1st if you count the ground floor).
    "Woow-woo.. It's a strange word 'Kamchatka'!" ;-)

    Together with my Juniper Networks Sales Specialist certificates (three)
    I received one optical usb mini-mouse (about 2x6 cm).

    Why not three minimouse per one certificate?!


    GChemPaint and gnome-chemical-utils russian translations were uploaded by Jean.

    I'm reading Ch.3 of Sybex Study Guide. Much better than Wiley's book.

    GChemPaint (CVS Head) was translated about 80%.
    Now I need to compile and run it to test my translation.
    I found that related projects (gchemutils, chemical-mime-data) aren't translated also,
    and 'm going to translate them.
    'CISSP Prep Guide' is finished. I read Sybex study guide now.

    Today I found that GChemPaint is not translated to russian!
    In between my previous lifes I wanted some free organic chemistry editor
    and was a hard user of 3 or 4 proprietary win16/dos program.
    So it's time to translate =)

    Payment for my CISSP exam attempt at December has been confirmed by boss.
    So at the monday I'll try to register. Hope a seat is available =)

    I read chapter 4 ('Cryptography') of 'CISSP Prep Guide'.
    I can eat about 1 chapter per day from this book, therefore it will be closed in a week.
    It's old and outdated quick-brief-review-like thingy I bought about 5 years ago, so I doubt it covers modern version of exam content.

    Next I'm going to read Sybex 'CISSP Study Guide'.

    In the mailbox I found an invitation to special meeting for 'e-Russia' government program. "Using of open source in the state organisations" or so. I introduce russian GNOME for this kind of events.

    May be I need to collect some facts on the topic 'Open Source and Government/State relations' for some european countries, because there is a similar agenda item.

    Today I overlooked some free Abkhasian fonts.

    Unfortunatelly (? ;-) all of them are TTF, so it's hard to quickly decide how good/bad them are. Most likely ttf instructions were generated automagically, so I safely can suggest that outlines of glyphs aren't perfect.

    As I can see there is a little difference between a "latin + russian" and "abkhasian" font. Abkhasian one uses some glyphs that are close to latin/cyrillic and can be simply made by modification of suitable glyphs. So it's possible to cover abkhasians by simple extention of the gnu-gs (aka URW) fonts.

    New Advogato Features

    New HTML Parser: The long-awaited libxml2 based HTML parser code is live. It needs further work but already handles most markup better than the original parser.

    Keep up with the latest Advogato features by reading the Advogato status blog.

    If you're a C programmer with some spare time, take a look at the mod_virgule project page and help us with one of the tasks on the ToDo list!
