NinjaVideo.net Founder Gets 14 Months

Warlord88 Re:Meanwhile... (239 comments)

Interesting. Usually, I would have expected Farkas to wiggle out with the help of $$ and serve little to no time, which is the case with almost every rich guy. But in this case, it seems that he is still serving time! From Wikipedia:

Farkas is currently serving his sentence at the Federal Correctional Institution, Williamsburg, a facility in South Carolina that holds minimum and medium security inmates, and is scheduled for release in 2037

India To Cut Out Animal Dissection

Warlord88 Re:Its about revering life, I think (145 comments)

Religion? Eating meat? Utter nonsense. I know this is Slashdot and no one RTFA, but if you have a claim, you can quickly look it up using the Ctrl-F supercombo key.

India is following a global trend to phase out animal dissection, or to make it voluntary, despite opposition from scientists who say that the experience is impossible to replicate with models.

India’s ban comes after pressure from animal-rights groups such as the Indian arm of PETA (People for the Ethical Treatment of Animals), based in Mumbai, which used Bollywood celebrities in a high-profile campaign to bring college students on side

Ask Slashdot: Statistical Analysis Packages For Libraries?

Warlord88 Re:R or WEKA ... Wait, What Exactly Are You Doing? (146 comments)

Why do you think R is not easy to implement? My company has been using SAS for a long time and we are finally making the change to R. As far as OP's requirements are concerned, I think R is way superior to SAS or SPSS because of its free, modular nature. It is clean, simple and suitable for a wide range of users. The commercial packages are filled with way too much business lingo garbage for me.

I personally think commercial support is overrated. I can install software on my own. I know how to browse through manuals and other information to find what I need. For a package like R, I almost always get any questions answered in at most few hours on online forums. So what exactly do I get from commercial support for my money? But, if OP needs commercial support, there is an enterprise edition of R by Revolution Analytics located here: http://www.revolutionanalytics.com/products/revolution-enterprise.php. Might be worth looking into.

Bottom line: R all the way.

Ask Slashdot: Clusters On the Cheap?

Warlord88 Theoretical analysis (264 comments)

OP hasn't mentioned a lot except budget. Since you are on such a tight budget, I would highly recommend doing some theoretical analysis first. Do you have a serial code? How much parallelism exists in the code? You say the task is 'very parallel', but Amdahl's law (which is really common sense) will tell you that even for small amounts of serial sections of code, your speedup will be limited. You should also consider the amount of time the code actually runs. Achieving a speedup of 2 for a serial code that runs for one minute is near worthless.

After you estimate speedup, do some rough calculations on the basis of average cost of a processor and the the number of processors required. This should give you an estimate of the hardware cost required. Compare that with the cost of CPU cycles per dollar you get using a cloud service such as Amazon.

How Linux Mastered Wall Street

Warlord88 Re:Customizable Kernel (339 comments)

Yup, the physical distances cannot be ignored anymore. If fact, they try to place the servers as physically close to the corresponding stock exchange as possible in order to avoid speed-of-light delays!

How Linux Mastered Wall Street

Warlord88 Re:Customizable Kernel (339 comments)

This is purely my guesswork, but I think that the benefits would be marginal. An improvement of 1 fps might not be convincing for game devs to modify the kernel. However, if you can execute even a single trade before others do, and multiply it by the number of trades executed per second (which must be in millions), the profit margin would be non-trivial.

How Linux Mastered Wall Street

Warlord88 Customizable Kernel (339 comments)

As mentioned in the summary, linux allows the firms to modify the OS kernel to serve their purpose. For example, the performance of trading algorithms would considerably degrade if context switching is allowed. So you can modify the kernel so as to dedicate certain cores for the main algorithms to which the OS can pass a very limited number of signals.

I know for a fact that at least one bank employs this in their high frequency trading group and probably all of them do.

Researcher Predicts Your Next Facebook Friend

Warlord88 Re:Article lacks important information (66 comments)

To me, it seems like a simple Machine Learning problem. The number of common friends will obviously be the most influencing input parameter followed by school, work place, etc.

Unless someone makes me understand the complexities underneath, I am going to assume that anyone can solve this problem by taking one course in Machine Learning.

Study Compares IQ With Browser Choice

Warlord88 Re:All of those studies are the same (380 comments)

Exactly. It is also one of the reasons why some sites such as reddit start out being genuinely intellectual and as the user base grows, they progressively become just banal - which is what reddit is today.

The study in TFA indicates nothing.

Cornell Software Fingers Fake Online Reviews

Warlord88 Re:Stupid project (122 comments)

It includes reviews by anyone who has never used the product. Example, this Zenith watch. I won't debate the hilarity of the reviews, but no doubt they are fake.

I think the "undecidability" factor comes into play in any machine learning problem. For example, which email is spam and which isn't? But significant strides have been made to solve that problem and I don't see why online review system is any different.

Hillary Clinton Takes Data.gov Overseas

Hillary Clinton Takes Data.gov Overseas

Warlord88 Re:Realy? (250 comments)

The current law stipulates that no more than 65,000 H1-B visas be issued each fiscal year. As of July 18, only 20,500 of these are filled. Of those, around 12,800 hold a Master's degrees. Are you suggesting that stopping the H1-B program is going to improve employment in US? No. What you'll be doing is reducing the quality of workers in American workplaces.

As regards to removing taxation, I am somewhat ambiguous. One could argue that since H1-B holders are not eligible to receive Social Security benefits, so they should not pay taxes However, a significant number of H1-B holders stay on to obtain a green card, making them eligible for the said benefits. Personally, I have no problem paying the Social Security taxes. The job that I am going to start in a month or so is fairly high-tech, the work is very intellectually stimulating and is simply not done in my home country. I am more than happy to help the currently unemployed Americans by paying my share of taxes. I view this as a price I pay for the better living conditions and greater job satisfaction. Mind you, that does not mean that either of them will be able to do my job. If any American is as skilled as I am, he won't have any problem getting a similar job position as mine.

Bank sues Google for identity of Gmail user

Warlord88 Warlord88 writes  |  more than 4 years ago

Warlord88 writes "A US bank is suing Google for the identity of a Gmail user after a bank employee accidentally sent the user a file that included the names, addresses, tax IDs, and loan info for more than 1,300 of the bank's customers.

After a failed attempt to recall the email, the employee sent a second note to that wrong address, requesting that the confidential email be deleted before it was opened. There was no response, so the bank contacted Google to determine what could be done to ensure that the confidential info remained confidential. According to the court papers, Google would not provide information on the account unless it received a subpoena or "other appropriate legal process." So the bank sued.

In recent weeks, Google has also received court orders to reveal the identities of those behind stories published in an online newspapers based in the Turks and Caicos Islands and of a blogger who castigated a model on a blog entitled "Skanks in NYC." ®"

College spammers face 10 years in prison in $4.1M

Warlord88 Warlord88 writes  |  more than 5 years ago

Warlord88 (1065794) writes "Four individuals were indicted by a federal grand jury in Missouri this week for spamming more than 2,000 colleges and universities across the US. The team first started on their scheme at the University of Missouri and then branched out, hitting up nearly every college and university in the country. As a result, the spammers and their company were all charged in a 51-count indictment that includes fraud in connection with computers, fraud in connection with e-mail, conspiracy, and violations of the CAN-SPAM Act.

In total, the defendants face over 50 charges stemming from their activities. The indictment also contains a forfeiture allegation that would require the team to give up their $4.1 million in proceeds along with two residential properties in St. Louis, a property in Columbia, a 2001 BMW, and a 2002 Lexus."

How Many CPU Cores Do You Need?

Warlord88 Warlord88 writes  |  more than 5 years ago

Warlord88 (1065794) writes "In the early years of the new millennium, with CPU clock speeds finally accelerating past the 1 GHz mark, some folks (including Intel itself) predicted that the company's new NetBurst architecture would reach speeds of 10 GHz in the future. However, physics doesn't allow for exponential increases in clock rate without exponential increases in heat, and there were a number of other challenges to consider, such as manufacturing technology. Indeed, the fastest commercial CPUs have been hovering between 3 GHz and 4 GHz for a number of years now. The trouble with parallelism is that software has to be specifically written to run in multiple threads--it doesn't offer an immediate return on investment, like clock speed. Back in 2005, when the first dual-core CPUs were seeing the light of day, they didn't offer much in the way of tangible performance increases because there was so little desktop software available properly supporting them. In fact, most dual-core CPUs were slower than single-core CPUs in a great majority of tasks because single-core CPUs were available at higher clock speeds.

Which begs the question: how many CPU cores are right for me? Is a triple-core processor good enough for gaming, or should you splurge on a quad-core chip? Is a dual-core CPU good enough for the average user, or do more cores really make a difference? Which applications are optimized for multiple cores and which ones react only to specifications like frequency or cache size? Tomshardware runs a series of benchmark tests for various applications and comes to a conclusion"

Windows 7 to have an 'XP Mode'

Warlord88 Warlord88 writes  |  more than 5 years ago

Warlord88 (1065794) writes "Microsoft is trying to make it easier to sway users of Windows XP onto the latest version of its operating system.

For some time now, the company has been quietly building a "Windows XP mode" that uses virtualization to allow Windows 7 to easily run applications designed for Windows XP. According to sources familiar with the product, the application compatibility mode is built on the Virtual PC technology that Microsoft acquired in 2003, when it scooped up the assets of Connectix.

Late on Friday, Microsoft confirmed XP Mode in a blog posting. "Windows XP Mode is specifically designed to help small businesses move to Windows 7," Microsoft's Scott Woodgate said in the blog. "Windows XP Mode provides you with the flexibility to run many older productivity applications on a Windows 7 based PC.""
