“Famous is as famous does” to
misquote Forrest Gump
"Two hundred hackers from
around the world gathered at a Miami Beach hotel Thursday and Friday
for the Infiltrate Security
conference, which focuses on systems
hacking from the 'offensive' perspective (with
slides). In a keynote address, Stephen Watt, who
served two years in prison for writing the software used by his
friend Alberto Gonzalez to steal millions of credit card numbers from
TJX, Hannaford and other retailers, acknowledges he was a 'black hat'
but denies
that he was directly involved in TJX or any other specific job.
Watt says his TCP sniffer logged critical data from a specified range
of ports, which was then encrypted and uploaded to a remote server.
Brad 'RenderMan' Haines gave a presentation on vulnerabilities
of the Air Traffic Control system, including the FAA's 'NextGen'
system which apparently carries forward the same weakness of
unencrypted, unauthenticated location data passed between airplanes
and control towers. Regarding the recent potential exploits
publicized by Spanish researcher Hugo Teso, Haines says he
pointed out similar to the FAA and its Canadian counterpart a year
ago, but received only perfunctory response."
I had never heard of a “database
right.” Who says I'm too old to learn new words? (Note that they
did not cancel his userid when he left the firm.)
Out-Law.com reports:
A man who sold
databases belonging to a former employer on eBay has been found
guilty of database rights infringement.
The High Court
also found the man who purchased the databases, and the woman who
subsequently marketed them for sale to others, guilty of database
rights infringement.
The employee,
referred to as ‘Mr Wall’ in the High Court’s judgment, admitted
to using login details he was given whilst employed by Executive
Grapevine International Limited (Grapevine) to access
Grapevine’s database after he had left his employment at the firm.

I often think, nothing teaches as good
as a bad example. Here's how NOT to do it.
Last summer we followed the odd case of
lawyer Charles Carreon, as he went
after Matthew
Inman, creator of The Oatmeal webcomic, with legal
threats. Carreon had been hired by FunnyJunk, a website Inman
accused of stealing his comics. Carreon demanded $20,000 in
compensation for Inman's "false accusations." Inman
declined, and then used the publicity to solicit over $200,000 in
donations, which he gave to charity after sending
Carreon photographs. Carreon dropped the suit against Inman, but
the saga continued. A satirical website was set up about Carreon,
which caused him to invoke the legal system again. The article
documents the absurdities, which included further legal action and a
song. Now, however, Carreon is reaping what he has sown; a
judge has ordered him to pay over $46,000 for his role in the legal
circus.
Once again, cities have the opportunity
to install (and therefore own) the fiber connections to their
citizens (and schools and businesses...) If “universal access”
is truly desireable, this is how to achieve it. Once in place,
cities have a continuous stream of income from the ISPs, cable and
other entities renting access on the “last mile” connections.
"A few years ago, when Google
was determining which city to launch its pilot Google Fiber program,
cities all over the country went all-out trying to persuade the
search giant to bring all that fantastical bandwidth to their neck of
the woods. And with good reason: Google Fiber offers gigabit
Internet speeds and even TV service, all at prices that meet or beat
the competition. In fact, the lowest tier of Google Fiber
service (5Mbps down, 1Mbps up) is free, once users pay a $300
construction fee. If ISPs
were concerned before, they should really start sweating it now.
Although Google Fiber looked like it would whip traditional ISPs in
every regard, with Time Warner Cable cutting prices and boosting
speeds for users in Kansas City in a desperate attempt to keep them,
surely other ISPs were hoping the pilot program would flame out. Now
that Austin is happening, it's clear that it's only a matter of time
before Google rolls out its service in many more cities. Further,
this jump from legacy Internet speeds to gigabit-class service is not
just about people wanting to download movies faster; it's
a sea change in what the Internet is really capable of."

teacher teaching lessons on basic mathematics, geometry, and algebra.
In all there are more than 300 video lessons. Like most mathematics
tutorials on YouTube, Math Class With Mr. V uses a whiteboard to
demonstrate how to solve problems.
The Open University is one of my go-to
YouTube channel for all things academic. A quick search on The Open
University reveals seven
playlists that include lessons in mathematics. The lessons that
you will find in these playlists are more theoretical than they are
"how to" lessons.
Yay
Math! features an excited teacher teaching mathematics lessons to
his students. The videos capture just the teacher and his whiteboard
with some feedback from students. The videos cover topics in Algebra
and Geometry. You can check out the Yay
Math! companion website to learn more about Robert Ahdoot, the

Good Places to Learn to Write HTML
A
Beginner's Guide to HTML & CSS is a nice resource developed
by Shay Howe whose resume reveals that he works on the user interface
for Groupon among other projects. There are currently ten text-based
lessons for beginners. Once you've mastered the beginner lessons you
can try your hand at the advanced lessons.
Codecademy
is a place where anyone can learn how to write code.
Codecademy offers
lessons in basic HTML and CSS. Codecademy's
lessons in basic HTML start with the very basics of explaining
what HTML is, what it does, and how to write the basics. There are
seven progressively more difficult lessons that students can work
through on their own.
Thimble
is a free Mozilla product designed to help users learn how to write
HTML and CSS. Thimble features a split screen on which you can write
code and see how it works at the same time. On the left side of the
screen you write your code and on the right side of the screen you
instantly see what that code renders. The latest version of
Thimble
gives you the option to start from scratch or to modify sample
projects. The sample
projects include directions for writing code. If you write the
code correctly, you will know right away. Likewise, if you don't
write the code correctly, you will know right away. Some of the
sample projects you can work with include webpages, games, and
avatars.
w3Schools
has long been my go-to place for quick directions when working in
HTML. If I get stuck while working on a project, a quick visit to
w3Schools usually reveals the help I need to get past a stumbling
block. If you're brand new to writing HTML start with the
introductory sections of w3Schools to learn the basics.
YouTube is another
of my go-to places for tutorials on writing HTML and many other
things. Whether you want an introduction to writing HTML or you just
need a quick tutorial to get you past one little obstacle in your
code, there's probably a video for you. Here's
one very popular video for beginners.
For my Intro to IT students, and my
Math students who are already using WolframAlpha.
WolframAlpha
Facebook Report
WolframAlpha will provide you with an
extremely detailed analysis of your own Facebook data including
visualizations, world clouds, graphs, and more.
Here’s how:
- Go to WolframAlpha.com.
- Type “Facebook Report” and execute the search.
- Allow WolframAlpha to have access to your Facebook account by clicking on “Analyze my Facebook Data” and following the directions.
- Wait while the data is analyzed.
Note: Sometimes the report seems to
stall after 100% of the data is analyzed. If this happens, simply
repeat steps 1-3. The second time, the report seems to load just
fine.
