OR anyone with interest in the subject of security and data recovery, I hereby link to finalised slides from my presentation yestersay.

• PC Security in a Connected Environment (XHTML)
• Basics of Data Recovery (XHTML)

Both parts were composed with the audience of Ophthalmic surgeons in mind. Expect them to cover the subjects at a relatively shallow level. I am pleased to say that my session is said to have been “well-structured and delivered”.

I sometimes get curious as to the background of some authoritative figures. Here are some interesting facts, which should not be treated as gossip, but strictly as objective facts. Bill Gates at his early days is described in an outdated mini biography, a snippet of which lies below:

His (Bill’s) great-grandfather had been a state legislator and mayor, his grandfather was the vice president of a national bank, and his father was a prominent lawyer.

Larry Page and Sergey Brin of Google, who now share a large Boeing 767 passenger plane, appear to have come from so-called “academic families”. Page’s father, Carl Victor, is a computer science professor at Michigan State University, where Larry also began his studies. Brin likewise, but it is the University of Maryland where his father Michael works on mathematics. His mother appears to have worked (possibly still does) in NASA.

The facts above make one wonder if a family of overachievers is a pre-requisite for success. I hope this is merely a coincidence that which not broadly reflect on reality. I can honestly confess that my parents were never educated at a high level. In fact, computers are known to them only at a fundamental level, e.g. Web surfing and Microsoft Word.

HERE appears to have been a recent growth in PageRank and SEO analysis tools. Such tools have an on-line front-end (interface) so they are easily and readily accessible. Here is a short survey of tools that not only have I used, but I can also confirm are valuable:

• Simple PageRank prediction tool (RustyBrick)
• Tippy PageRank comparisons (temporary location)
• Multi-URL PageRank prediction
• Search engines saturation check
• Google cache lookup
• Google datacentres and IBL‘s
• Netcraft uptime statistics – risk factor, server, and host lookup
• Page analysis and optimisation

ODAY marks a milestone as I submitted my 2^nd Year Progress Report (PDF, HTML). My 1^st year report was enormous in comparison, totalling at 202 pages which went under the heading Continuation Report (PDF, HTML). Last month I started to work on my thesis and distributed my L_yX (front-end to L^AT_EX) template among the L_yX users community. This template appears to have become quite popular, which entails a rewarding feeling.

I am expecting to complete my Ph.D. next year, at the age of 24. As for future paths: academia is appealing, industry is appalling and otherwise all is confusing. The next stage remains undecided. I will have to ponder and come up with a decision within the next couple of months. I would like to sincerely thank all my readers, who have unknowingly motivated me to carry on with some heavy burdens. I have recently come under great pressure due to involvement in many (technical) support-related groups, as well as my jobs and the degree program at the University. I am glad to say that I have regained full control and can now cope with all my commitments and obligations.

Here is a little riddle. Can you spot the special meaning of the number below? (hint)

I think the above can be considered a case of lateral thinking, which is one way of educating CS students and sharpening up their programming/testing skills. As strange as it may seem, I spent hours with tutors solving problems like the classic below:

A hunter aimed his gun carefully, and pulled the trigger. Seconds later he realised his mistake. Minutes later he was dead. What happened?

Clues: No living creature killed him. It was a cold winter’s day. He had a VERY loud gun…

Solution: The hunter was near a snowy cliff. When he fired the gun, he “triggered” an avalanche which buried him…

Hint: Try to see which English word the numbers form.

Blackhat SEO’s: under the illusion that they are talented gunslingers, shooting from the hip

have recently become aware of highly dirty practices, which sometimes get used by malovalent SEO‘s. ‘Googleating’ is one of the most vile SEO methods, perhaps only second to spam. I have been told about someone who developed a habit of conquering deleted blogs immediately once they had been freed. Then, it was promptly possible to ‘fuel’ his own adverts-filled public content sites, making use of merit (mainly in the form of Google PageRank), which got transferred owing to links in these recently-acquired blogs.

Further on the issue of dodgy practices, in order to compensate for banishment from search engines, that same person bought multiple domains; thus, he avoided putting all eggs in one basket.

How did I come to find this out? There is an exceptional user in a benevolent SEO forum that I participate in. He uses blackhat techniques and gives the group a bad reputation that may sooner or later draw attention from search engines, which in turn can inflict collective punishments on group participants. If justice pervails, bad practices will be choked and genuine sites will receive more referral traffic from search engines. The Internet is no place for mirrored public content, neither it is for link spam.

Longhorn (Vista) alpha: looks promising, but how much computer power will it devour?

have just come across an interesting speculation according to which the release of Windows Vista might give a boost to Linux on the desktop. The oxymoron did not surprise me much as I tend to agree that it Vista will be indictor of staticity. As I have argued before, Vista (formerly knows as Longhorn) excludes many of the lucrative features it was set to implement. Once it hits the market, people may conclude that Vista is uninnovative when compared against Windows XP, which in itself is similar to Windows 2000 ‘under the hood’. Moreover, Vista has some high requirements from hardware — an issue that Linux distributions do not suffer from.

As the time gets closer and closer to the public debut of Vista the operating system seems to be constantly losing the luster which was associated with Longhorn.

…

If this was not enough to turn people off from Vista, there are the hardware requirements.

…

Noting the problems with the arrival of Vista, an effort should be made to get people on desktop Linux distributions.

Speaking of desktop Linux, I purchased a new computer this morning. It should arrive my home within a day or two. The machine will have Mandriva pre-installed, but I might wipe everything off to put Ubuntu or SuSE on it. It is yet undecided.
