Why Open Source is good

with one comment

In 1995 UNLV named an internal HP OCR engine one of the best OCR engines, Tesseract OCR. In the period between 1995 and 2006 little work was done on it, but when it was release to the FOSS community it was picked up and, according to the site, “…one of the most accurate open source OCR engines available.

If it hadn’t been released it would have probably remained on a HP CVS somewhere collecting dust, thanks Carly.

USB Firewall Key

with 2 comments

I was reading my backlog from LinuxDevices and came across a Windows firewall squeezed into USB key. It works by placing a driver between the Windows TCP/IP stack and the device driver; wifi, ethernet, tokenring, etc. The data is routed through the USB key as is goes to and from the internet to the pc.

It contains:

  • Anti-Spam
  • Anti-phishing
  • Antispyware
  • Antivirus
  • Parent control system
  • Transparent email proxies (POP3; SMTP)
  • Transparent web proxies (HTTP; FTP)
  • Intrusion detection system
  • Intrusion prevention system
  • Firewall
  • Adaptive security policy
  • Multi-layer security agent (Patent pending)
  • “Layer-8” security engine (Patent pending)

Clothing for Coding

with one comment

Who knew that you had to dress in a specific way? My friend Tom Hudson figured it all out for me in
How to dress for a coding interview.

What that means is that I wear a T-shirt, jeans, ballcap and sneakers. Have a flip-phone and an OpenOffice resume and drink real beer. (Not the 5% piss.) I use Gentoo, does that mean I have to make all my clothes myself?

I went for a pre-sales security position yesterday, I wore a $500 suit, $300 sneakers and a $100 pair of sunglasses.

Playing with Gnip (Proof of Concept)

with one comment

I mentioned Gnip before, and this afternoon I was browsing the API definition and wanted to see if I could add my own publisher.

First I wanted to see how the messages are polled, so I crafted a wget command to retrieve some example data:

wget -nv --http-user="*username*" --http-passwd="*password*"

The search for a Multi-Messenger

leave a comment »

Today I went of a forray of chat clients, I needed one to connect to multiple networks as I have ICQ, Yahoo! and MSN. I tried the following:

  1. centericq (FreeBSD/Gentoo Linux)
  2. Gaim (FreeBSD/Gentoo Linux)
  3. licq (Gentoo Linux)
  4. micq (Gentoo Linux)
  5. AdiumX (MacOSX)
  6. Trillian (WinXP)
  7. Jabber (WinXP)
  8. GoogleTalk (WinXP)
  9. ebuddy (formally emessenger) (Web Based Messenger)

centericq (FreeBSD – centericq-4.12.0/ centericq-4.13.0) which were on my provider’s shell both kept crashing with Bus Errors or Segmentation Faults. Must be their installation.

centericq (Gentoo – centericq-4.21.0-r2) in an empty Gentoo vserver, sadly the ebuild isn’t too good, which means I would need more beside the net-im/centericq package.


~ # emerge --ask --tree centericq

These are the packages that I would merge, in reverse order:

Calculating dependencies ...done!
[ebuild N ] net-im/centericq-4.21.0-r2

Do you want me to merge these packages? [Yes/No] y

Some downloading and configuring later I see this configure line:

./configure --codefix=/usr --host=i686-pc-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --disable-konst --enable-locales-fix --with-ssl --with-ssl --disable-icq --disable-jabber --disable-aim --disable-msn --disable-yahoo --disable-irc --disable-rss --disable-lj --build=i686-pc-linux-gnu

Not as easy as I thought it would be, I would have to install a load of other packages before I could install centericq. That combined with the fact that I don’t really want a terminal chat to complement my mutt.

Gaim (WinXP sandboxie – gaim-1.5.0.exe) made me install GTK 2.6.9 and Aspell 0.50-3 on a machine which has these installed under cygwin. A little irritating was that I could not figure out within the first 30 minutes how to connect to multiple networks at the same time. So I uninstalled it and all the packages I didn’t need.

Gaim (Gentoo – net-im/gaim-1.5.0) on Gentoo is a whole different story, everything and it’s mother needs to be installed. That’s not really what I had in mind for a quick install.

~ # emerge --pretend --tree gaim

These are the packages that I would merge, in reverse order:

[ebuild N ] net-im/gaim-1.5.0

licq (Gentoo – net-im/licq-1.3.0) I went to install licq but realized that it doesn’t support Yahoo! messenger.

~ # emerge --pretend --tree licq

These are the packages that I would merge, in reverse order:

[ebuild N ] dev-libs/libgpg-error-1.0-r1

micq (Gentoo – net-im/micq-0.5.0.3) is a ICQ only solution.

~ # emerge --pretend --tree micq

These are the packages that I would merge, in reverse order:

Calculating dependencies ...done!
[ebuild N ] net-im/micq-0.5.0.3

[ebuild N ] dev-libs/libgpg-error-1.0-r1

AdiumX (OSX – *.dmg) Problem being that I don’t have my iMac as I gave it to my sister to use, so I wouldn’t have to solve her computer problems any more.

Trillian (WinXP sandboxie – trillian-v3.1.exe) requires an install of QuickTime. I got to choose between Basic and Pro, as I didn’t even know if I like the Basic functions I selected Basic. It then installs the elements I want to use as plugins.

Jabber (None – none) I didn’t try as Trillian fit my needs. Anybody with an opinion for any platform I will gladly post it.

GoogleTalk (None – none) I didn’t try as Trillian fit my needs, but I did find this article

ebuddy (formally emessenger) (Web Based Messenger) by a good friend of mine, handy as a stop gap, but I like a local client. Very handy.
