Welcome to the Aperi Blog

The Aperi project announces the first release of the Storage Network Simulator. The simulator is a tool that enables you to simulate a storage area network (SAN) through software. You can create a SAN configuration, add devices to the SAN, create arbitrary connections between devices, and remove connections between devices. Using this tool to create a simulated SAN environment can help when you:

  • Have limited or no access to hardware and software when developing and testing SRM applications
  • Have "off-line"' access to SAN devices without impacting the performance of the real network (such as the SNIA lab or any SAN in the world).
  • Need to perform "what-if" analysis before you plan to extend or reconfigure your SAN
The SAN Simulator provides an increase in productivity and efficiency for Aperi development and testing by removing the dependence on device availability.

Don't convert to marry, says Muslim seminary

An Islamic seminary in Muzaffarnagar has issued a fatwa saying that conversion of a woman to Islam for the purpose of getting married with someone from the faith is illegal and against the Shariat.

The fatwa was issued in response to a question posed before the Darul Uloom Deoband asking whether the conversion of a non-Muslim woman into Islam for the purposes of marriage was justified.

Ray tracing (graphics)

In computer graphics, ray tracing is a technique for generating an image by tracing the path of light through pixels in an image plane. The technique is capable of producing a very high degree of photorealism; usually higher than that of typical scanline rendering methods, but at a greater computational cost. This makes ray tracing best suited for applications where the image can be rendered slowly ahead of time, such as in still images and film and television special effects, and more poorly suited for real-time applications like computer games where speed is critical. Ray tracing is capable of simulating a wide variety of optical effects, such as reflection and refraction, scattering, and chromatic aberration.

Be more productive

Hard work isn't supposed to be pleasant, we're told. But in fact it's probably the most enjoyable thing I do. Not only does a tough problem completely absorb you while you're trying to solve it, but afterwards you feel wonderful having accomplished something so serious.

So the secret to getting yourself to do something is not to convince yourself you have to do it, but to convince yourself that it's fun. And if it isn't, then you need to make it fun.

Storage Management - Green IT not green

Note that the term “under storage” is substituted for “under management.” Truth be told, data management in distributed computing environments is extraordinarily lax. The best analogy for distributed storage is a huge and growing junk drawer. This point is underscored by data collated by Sun Microsystems after performing nearly 10,000 storage assessments at client facilities. Per Sun’s statistics, for every hard disk deployed by a company, roughly 30 percent of its capacity contains useful data accessed regularly as part of day to day operations. Another 40 percent must be retained for reasons of historical value, regulatory or legal compliance, or because it is intellectual property. Rarely referenced, this data belongs in an archive, preferably tape or optical because they consume far less kilowatt hours than do disk-based systems.

The balance of the space on each hard disk, some 30 percent of total disk capacity, comprises orphan data (whose owner of record no longer exists at the company), contraband data (collections of MP3 files, videos or pictures downloaded from the Internet), and good old fashioned wasted space that has been reserved by an application or file system, but never used. This capacity could be freed up through a combination of data hygiene and good storage resource monitoring and management. If that were done, and archiving was implemented, companies could return up to 70 percent of the capacity of every spindle they own today, deferring the need to invest in more storage and exacerbating the storage acquisition trend that IDC projects will total 300 percent by 2011.

This point is never brought up in the articles you read in the trades. Instead, vendors posit a number of hardware and software value-add solutions as silver bullets for Green IT. Virtualization, de-duplication, compression, re-driving arrays with larger disk drives, leveraging MAID (massive arrays of independent disk, a portion of which spin down when not in use), and thin provisioning are just a few of the green panaceas that are being discussed. Most involve plugging additional hardware into the wall, which is hardly an intelligent way to reduce power consumption.

All of these techniques deliver tactical value at best: unmanaged data will continue to grow over time and eliminate whatever short term power reductions that the new technologies deliver. They are simply re-arranging deck chairs on the Titanic. Getting to green in IT ultimately and strategically comes down to managing data better. It costs a company virtually nothing to sort out their data junk drawer, to apply processes for classifying data so that it can be migrated over time into an archive, and to deploy storage resource management tools to spot wasted space, ownerless files and junk data in their repositories.

beliefs

Most of us, when overcome by those unmistakable feelings of disconnectedness from our surroundings, experience a sense of inner agitation of a peculiar kind. When human affairs are pressed beyond the ordinary, such as when at war, these moments of disconnectedness steer us to identify things that are “right” or “wrong.” Soon these moments turn into beliefs. Then we become emphatic about these beliefs. Then we suddenly find it easy to relate our normal day-to-day occurrences to these beliefs.

But this disconnect, the inner agitation, doesn't go away. It seems to persist despite our emphatic beliefs of right and wrong. This feeling, instead of getting resolved, dissolved, disappear and reassure us in the staunch positions we take on the issues of political importance, seems to go right past our ordinary day-to-day beliefs and is still left dangling, in search of home.

Textbooks and The Teaching Company

Regardless of how it is either in U.S. or whatever (because they are all screwy), if we ask ourselves a question: “How would you address this text book problem from a business point of view, so that you are both solving a real problem and making money by doing that?” we should at least see one aspect rightaway: that the printing costs are not really a big issue here. The distribution costs are, on the other hand, a big problem (as expected).

IT Employment Surges in May

While the unemployment rate jumped to 5.5 percent last month and job losses were widespread through many sectors of the economy, IT employment growth accelerated in May, according to the National Association of Computer Consultant Businesses (NACCB), which tracks monthly IT employment.

The association reported IT employment reached 3,899,800 in May, which was a gain of nearly 37,000 jobs from the previous month. So far this year, IT employment has grown by more than 80,000 jobs. IT employment is up 8.6 percent, or more than 300,000, from May 2007.

:: The Future of the Internet — And How to Stop It

This extraordinary book explains the engine that has catapulted the Internet from backwater to ubiquity—and reveals that it is sputtering precisely because of its runaway success. With the unwitting help of its users, the generative Internet is on a path to a lockdown, ending its cycle of innovation—and facilitating unsettling new kinds of control.

Pods, iPhones, Xboxes, and TiVos represent the first wave of Internet-centered products that can’t be easily modified by anyone except their vendors or selected partners. These “tethered appliances” have already been used in remarkable but little-known ways: car GPS systems have been reconfigured at the demand of law enforcement to eavesdrop on the occupants at all times, and digital video recorders have been ordered to self-destruct thanks to a lawsuit against the manufacturer thousands of miles away. New Web 2.0 platforms like Google mash-ups and Facebook are rightly touted—but their applications can be similarly monitored and eliminated from a central source. As tethered appliances and applications eclipse the PC, the very nature of the Internet—its “generativity,” or innovative character—is at risk.

The Internet’s current trajectory is one of lost opportunity. Its salvation, Zittrain argues, lies in the hands of its millions of users. Drawing on generative technologies like Wikipedia that have so far survived their own successes, this book shows how to develop new technologies and social structures that allow users to work creatively and collaboratively, participate in solutions, and become true “netizens.”

'Nova: scienceNOW' is light years from the norm

Gone are the days when a science show on PBS was the television equivalent of castor oil.

Tonight's season kickoff of "Nova scienceNOW" is more like a tall glass of really good lemonade.

It may not be quite as good for you, but it makes you want to come back for more.

One segment tells the inspiring story of how a once-wayward youth found his life's calling in computer science - and that one of his missions today is challenging phony celebrity photographs.

It all started, Hany Farid explains, with the semi-famous People magazine cover photo of Brad Pitt and Angelina Jolie.

It was widely thought to be a composite, a suspicion Farid confirmed by comparing the angles of light on their faces.

But he didn't stop there. He developed a computer program that analyzes light and pixels carefully enough for him to debunk other, more serious photo distortions - like an alleged photo of a bombed Lebanese city where thicker smoke had been added to the sky.

Farid describes himself as an "accidental scientist," which is the kind of relaxed attitude that Nova is after when it tells skeptical viewers, "Wait, wait, stay tuned. This isn't all about astrophysics."

Some of it, of course, is about astrophysics. The opening segment documents the search by scientists for "dark matter," an unseen form of matter that apparently affects the motion of the whole universe.

"Nova" treats the hunt for dark matter like a classic mystery with a fascinating, offbeat cast. Scientists work in a lab a half-mile underground so their search for this elusive matter is less likely to be compromised by unseen things zipping in from space.

Host Neil deGrasse Tyson, an astrophysicist himself, downshifts to populist terms as he acknowledges with some amusement that devoting your life to the search for the unseen is an unusual career choice.

Small Business and State Taxes

Oh, and a note for those of you who think there are only 50 state taxes to program into a lookup table. States like CA have different state rates based on location. There are over 7400 different state and local tax zones. And, Shan is right about each item having a possible different tax rate. Here food items specifically used to prepare meals are taxed at 1.5%, but the plates to serve the meal are taxed at 7.6%. It's a nightmare for just one store to figure out one state's tax code.

Journey of Man

The Bradshaw Foundation , in association with Stephen Oppenheimer , presents a virtual global journey of modern man over the last 160000 years.


The Genographic Project: Tracing Human Roots to a Single Origin

The Waitt Institute for Discovery is the key partner for the field research for an ambitious global project whose goals are twofold: to capture a snapshot of human history locked within our DNA before it disappears forever, and to highlight the untold stories and uncertain future of indigenous peoples worldwide.

The National Geographic documentary Journey of Man, which tracks human origins and migrations using DNA samples from around the world, has sparked a partnership with IBM to conduct the most significant research project in National Geographic's history, the Genographic Project.

The Genographic Project, a five-year research partnership, will use sophisticated laboratory and computer analysis of DNA contributed by hundreds of thousands of people, including indigenous peoples and members of the general public, to map how the Earth was populated. Led by National Geographic Explorer-in-Residence Spencer Wells, Ph.D., a team of international scientists and IBM researchers will collect genetic samples, analyze results and report on the genetic roots of modern humans.

With funding from the Waitt Family Foundation and support from the Waitt Institute for Discovery, the scientists will establish 10 centers around the world and will study more than 100,000 DNA samples from indigenous populations. The project is expected to reveal rich details about global human migratory history and to drive new understanding about the connections and differences that make up the human species.

Do Women Write Better Code?

Now that I've lived to see this day,
These are the things I must but say.

Die a bachelor, if your options are few,
Never ever love a female programmer,
they'll make a program out of you.

Don't laugh it away, mine has been an object lesson,
They find syntax errors, even in a romantic expression.

Alas! They search logic in love, where there is none,
Your heart may skip a beat and they just hit return.

You are in for trouble if you persist,
You'll just be a pointer in her long linked list.

Cargo Cult Science

But then I began to think, what else is there that we believe? (And I thought then about the witch doctors, and how easy it would have been to cheek on them by noticing that nothing really worked.) So I found things that even more people believe, such as that we have some knowledge of how to educate. There are big schools of reading methods and mathematics methods, and so forth, but if you notice, you'll see the reading scores keep going down--or hardly going up in spite of the fact that we continually use these same people to improve the methods. There's a witch doctor remedy that doesn't work. It ought to be looked into; how do they know that their method should work? Another example is how to treat criminals. We obviously have made no progress--lots of theory, but no progress-- in decreasing the amount of crime by the method that we use to handle criminals.

So we really ought to look into theories that don't work, and
science that isn't science.

I think the educational and psychological studies I mentioned are
examples of what I would like to call cargo cult science. In the
South Seas there is a cargo cult of people. During the war they saw
airplanes land with lots of good materials, and they want the same
thing to happen now. So they've arranged to imitate things like
runways, to put fires along the sides of the runways, to make a
wooden hut for a man to sit in, with two wooden pieces on his head
like headphones and bars of bamboo sticking out like antennas--he's
the controller--and they wait for the airplanes to land. They're
doing everything right. The form is perfect. It looks exactly the
way it looked before. But it doesn't work. No airplanes land. So
I call these things cargo cult science, because they follow all the
apparent precepts and forms of scientific investigation, but
they're missing something essential, because the planes don't land.

Business (LLC) and H1B - alt.visa.us | Google Groups

This advice is incorrect. US immigration law does not allow an H1 todonate their time to a business. You can volunteer your time to acharity or the like if you can prove that unpaid work is typical forother people at the charity in a similar position. I doubt you will findmany people 'donating' their time to a business.

As an H1, your investment in the LLC can only be passive i.e. you canattend shareholder meetings, invest money and take profit/loss which arereported on a form K1 attached to your US tax return. You cannotactively work for or manage the company. If there is nobody elseinvolved in the LLC, then you are automatically in violation (since youmust be doing the work).

If you are working for the LLC as described, you are in violation ofyour H1 status. Be careful. You should file for a concurrent part-timeH1 status ASAP.

You are now officially an illegal alien, out of status and deportable
pursuant to 237(a)(1)(C) of the INA.  The only question now, is if the
government will learn of the violation.

The Care and Feeding of FOSS: The Lifecycle of Software Technology

Stage 5. FOSS Domination

With the slow pace of innovation of the Maturity phase, the FOSS community begins to slowly but inexorably erode the technical lead held by the commercial offerings. FOSS versions of the technology may have been present all along, but the pace of innovation during the Expansion phase often left them in the dust. But now, with the technology mature and the pace of innovation slow, FOSS becomes the proverbial turtle, plugging along toward the finish line, slow but unstoppable. Feature by feature, the FOSS developers eat away at the commercial products.

The commercial suppliers are doubly cornered.

First, the product is no longer cutting edge, so staffing is reduced and management interest is low. Since there's little innovation, R&D costs are low, which means profits are high. Developers who want to innovate are discouraged, because there's little potential return on investment.

Second, the technology has expanded to the logical boundaries, and additional features are less and less relevant to the core technology. These two factors slow innovation dramatically in the commercial sector.

Sooner or later, the FOSS product not only matches the commercial products feature-for-feature, but the nature of open-source software makes the FOSS product more reliable, higher performance and (where security is a concern) more trusted.

During this "end game", there is often a series of attacks on the FOSS software by commercial suppliers.These vary but may include legitimate competitive attacks such as feature or performance comparisons and support issues. There may be a spurt of new R&D. Sometimes legalistic tricks are used to block FOSS acceptance, such as certification requirements that are incompatible with FOSS itself, or getting standards bodies to accept patented technology as a "standard". As FOSS continues to erode the commercial market share, the attacks often turn turn somewhat shady or desperate, such as unfounded claims of security problems, copyright or patent attacks, hints that FOSS is written by "foreigners" with unsavory motives, and other "mud slinging" tactics.

-----------------------------------------------------------

The Error of Hard-Core FOSS Advocates

There is a group of FOSS idealists who, for lack of a better term, I will call "hard core" FOSS advocates. I mean no disrespect by the term, in fact, I admire most groups who have strong ideals and work to achieve them. As folk-singer Arlo Guthrie says, "I'd rather have friends who care than friends who agree with me."

The hard-core FOSS advocates would like to go directly from Stage 1 (Innovation) to Stage 6 (The FOSS Era) and skip the whole commercial part. They argue that proprietary software ownership is undesirable at best, and immoral or unethical at the worst.

But ignores capitalism and human nature, and the economic forces that help fund and drive the creative process in Western society. In spite of fundamental differences between software and brick-and-mortar industries, software follows the same first four phases of the lifecycle.

Capitalism has a way of getting things done, of bringing resources and energy to a problem quickly and efficiently. When there's money to be made, capitalism can be a powerful, positive force. Investors pay handsomely, and innovators flourish in their pay. Capitalism fosters the basic competitive instincts of human nature

Capitalism also encourages an odd sort of "collaboration": Secrecy abounds, but innovation, once commercialized, spreads rapidly through the industry, sparking new levels of creativity and innovation. In addition, the profit motive encourages companies to "steal" one another's key personnel, further fostering this strange collaboration.

At the same time, capitalism stifles software innovation. Each company wants to get the edge, the latest feature, the one innovation that everyone will need and only they can provide. To achieve this, commercial vendors are secretive, and go to great lengths to protect their ideas and innovations. More importantly, once they invent something useful, they often will attempt to block others from the new technology. They'll use anything and everything to develop and keep a monopolistic position, including patents (sometimes absurd ones), highly-restrictive licensing agreements, lawsuits over alleged copyright infringement, employment contracts that turn employees into virtual indentured servants, and anything else they can think of to "protect their turf."

It is this behavior that bothers FOSS advocates. Capitalism is a double-edged sword for software. It both fosters and stifles innovation and collaboration.
