Performance tuning : Swappiness

I got my linux pc was slowing down because of swap. Then, I checked in htop, oh, my main memmory was about 1.5 GB left (totally 4 GB). Why swap was allocated util main memory was 85 or 90%? I ask a help from my senior. He said to google "Swappiness". I found one of the solutions and did as they said. Now, I am ok. I set vm.swappiness = 10 and rebooted.

Over a dozen dead, over 5 million without power as Sandy pummels the East Coast


Monster Storm Sandy slammed into the East Coast Monday, killing at least 14 people, hurling a record-breaking 13-foot surge of seawater at New York City and knocking out power to an estimated 5.7 million people. 
The massive storm was downgraded from a hurricane after it barged ashore in southern New Jersey, bringing more than 85-mph winds and a roiling wall of seawater as it moved through New York City. It sent water surging into two major commuter tunnels and into subway stations and tracks. It was unclear how much water had come in.
The 14 deaths were reported in New Jersey, New York, West Virginia, Pennsylvania and Connecticut. Some of the victims were killed by falling trees. Police in Toronto said a woman was killed by a falling sign as high winds closed in on Canada's largest city.

61,000 National Guard troops prep for Hurricane Sandy


ARLINGTON, Va. (10/27/12) – National Guard members and residents along the East Coast prepared today for Hurricane Sandy, which gained strength as it churned toward the eastern seaboard.
The storm was barreling north from the Caribbean and was expected to make landfall early Tuesday near the Delaware coast, then hit two winter weather systems while moving inland, creating the potential for a monster storm, according to the Associated Press.
At least 61,000 National Guard members are on hand, Guard officials said today.
As of 1:30 p.m. EDT today, governors in Connecticut, Maryland, New Jersey, New York, North Carolina, Pennsylvania, and Virginia and the mayor of Washington D.C., have declared states of emergency.

GNUs trick-or-treat at Windows 8 launch


Yesterday morning, the Free Software Foundation crashed the Windows 8 launch event in New York City. A cheerful GNU and her team handed out DVDs loaded with Trisquel, FSF stickers, and information about our new pledge, which asks Windows users to upgrade not to Windows 8, but to GNU/Linux.
Check out these great photos of the fun, and don't forget to sign our pledge!

Why Coding Style Matters


When I was studying computer science in college, I had one extremely tough professor. His name was Dr. Maxey and he taught the more complicated courses like data structures and computer architecture. He was a wonderful teacher with a talent for articulating difficult concepts, but also an extremely tough grader. Not only would he look over your code to make sure that it worked, he would take off points for stylistic issues.
If you were missing appropriate comments, or even if you misspelled a word or two in your comments, he would deduct points. If your code was “messy” (by his standards), he would deduct points. The message was clear: the quality of your code is not just in its execution but also in its appearance. That was my first experience with coding style.

B.C. teen arrested for photographing mall takedown

Lawyer says guards and police have no right to demand people's cameras

Security guards pin a man at Metrotown mall in an incident that led to a confrontation with the photographer. (Jakub Markiewicz)

A B.C. teen who aspires to be a journalist says his rights were violated when he was set upon by security guards and then arrested by police after photographing an incident at Metrotown shopping mall in Burnaby, B.C.
Jakub Markiewicz ,16, said he was in the mall in September and took a picture of what he thought was a newsworthy event — a man being arrested by security guards.
But Markiewicz said the guards quickly turned on him, demanding he delete the photo, which he couldn’t do because he was shooting on a film camera.
Markiewicz said he turned to leave the mall and then snapped a second shot as RCMP arrived.

Burma to Myanmar and Back? | GulfNews.com


In ways big and small, Asia is still living with the tainted legacy of imperialism. Consider the debate now underway in Myanmar – or Burma to some. Because the imperial tongue found it difficult to pronounce “Myanmar”, the country’s no-nonsense British masters renamed it “Burma” (redrawing its borders as well for good measure).
The new name stuck until the military regime that ruled the country for decades restored the original one in 1989. Ironically, however, the newly empowered democratic opposition would like to bring back the name Burma, viewing “Myanmar” as emblematic of the dictatorship that they wish to leave behind.

Boycott Sony : Why are we asking you to take action against Sony?


Boycott Sony

Why are we asking you to take action against Sony?

Sony is using legal actions to harass and intimidate individuals who are modifying their own PS3 systems. Defective by Design supporters are boycotting Sony. Here's the full story:
  • Sony sold the PlayStation 3 as a general purpose computer, capable of running the GNU/Linux operating system, but running in a restrictive mode that didn't allow complete access to the powerful hardware.
  • Sony stated, "It was fully intended that you, a PS3 owner, could play games, watch movies, view photos, listen to music, and run a full-featured operating system that transforms your PS3 into a home computer." In return, George Hotz (known in programming circles as geohot) announced his efforts to give PS3 owners complete access to their machine's powerful hardware.
  • Sony then proceeded to betray their customers by removing the ability to run custom operating systems at all, "due to security concerns."
  • In January 2011, Hotz released the cryptographic keys needed to reverse Sony's restrictions and run custom software on the PlayStation 3.
  • Sony promptly brought a lawsuit against Hotz.
  • Then, another PS3 hacker, Alexander Egorenkov (graf_chokolo) had his home raided by the police and sued him for €1 million. Sony followed-up by confiscating his equipment.

TSA Moving X-ray Body Scanners To Smaller Airports


The Transportation Security Administration has been quietly removing its X-ray body scanners from major airports over the last few weeks and replacing them with machines thatradiation experts believe are safer.
The TSA says it made the decision not because of safety concerns but to speed up checkpoints at busier airports. It means, though, that far fewer passengers will be exposed to radiation because the X-ray scanners are being moved to smaller airports.



Minnesota Gives Coursera the Boot, Citing a Decades-Old Law


Coursera offers free, online courses to people around the world, but if you live in Minnesota, company officials are urging you to log off or head for the border.
The state’s Office of Higher Education has informed the popular provider of massive open online courses, or MOOC’s, that Coursera is unwelcome in the state because it never got permission to operate there. It’s unclear how the law could be enforced when the content is freely available on the Web, but Coursera updated its Terms of Service to include the following caution:
Notice for Minnesota Users:
Coursera has been informed by the Minnesota Office of Higher Education that under Minnesota Statutes (136A.61 to 136A.71), a university cannot offer online courses to Minnesota residents unless the university has received authorization from the State of Minnesota to do so. If you are a resident of Minnesota, you agree that either (1) you will not take courses on Coursera, or (2) for each class that you take, the majority of work you do for the class will be done from outside the State of Minnesota.
Tricia Grimes, a policy analyst for the state’s Office of Higher Education, said letters had been sent to all postsecondary institutions known to be offering courses in Minnesota. She said she did not know specifically whether letters had been sent to other MOOC providers like edX and Udacity, and officials there did not immediately respond to questions from The Chronicle.

Ready for war: Turkey tanks and battleships at ready over Syria threat



War edged closer last night as Turkey lined up warships and tanks against neighbouring Syria.
Turkish forces were on yellow alert, one step away from military engagement, as naval destroyers moved in to protect their Mediterranean coast and a brigade of tanks rolled up to the 560-mile Syrian border.
The desperate military escalation came as the Turkish government warned it will smash President Assad’s forces if they dare to bombard towns north of their boundary again.
Syrian refugees fled for Turkey. And the UN stood reeling from the Turkish Prime Minister’s accusations of inaction against Syria’s shelling.
His artillery has hit back a dozen times in the past two weeks, killing 12 Syrian troops but fears are growing that fresh cross-border shelling will lead to war.

Meteor Shower Spawned By Halley’s Comet Will Peak Over The Weekend


A big celestial light show is underway as the Orionid meteor shower will reach its peak over the weekend. The Orionids are named after their source of origin in the constellation Orion (The Hunter). Historically, the Orinoid meteor shower has produced an average of 20 meteors per hour at its peak but it has been especially active in recent years.
The Orinoid meteor shower is one of two annual celestial events produced by pieces of the tail of Halley’s Comet. The other meteor shower from this source is called the Eta Aquarids and peaks every spring. Halley’s Comet returns to our solar system every 75 and is one of the largest–and certainly most famous–comets in existence. Halley’s comet last appeared in the mid 1980′s and is expected to return in 2061. Halley’s Comet is named after English astronomer Edmond Halley who originally spotted it and determined the timetable for its return. When it returned on schedule it was named ‘Halley’s comet’ as a posthumous honor.

FBI Warns of 'Skyfall' Attack

WASHINGTON -- In a brief but dramatic statement, the FBI warned Thursday that Americans should expect additional terrorist attacks.
A two-sentence press release on FBI.gov said there "may be additional terrorist attacks within the United States and against U.S. interests overseas over the next several days."
The content was disturbing enough, but even stranger was the Web address of the press release: http://www.fbi.gov/pressrel/pressrel01/skyfall.htm. The link was pulled about a half an hour after it was put up.

Curiosity discovers unidentified, metallic object on Mars



A few hundred million miles away on the surface of the Red Planet, Mars rover Curiosity has discovered… an unidentified, shiny, metallic object.
Now, before you get too excited, the most likely explanation is that bright object is part of the rover that has fallen off — or perhaps some debris from MSL Curiosity’s landing on Mars, nine weeks ago.
There is the distinct possibility, however, that this object is actually native to Mars, which would be far more exciting. It could be the tip of a larger object, or perhaps some kind of exotic, metallic Martian pebble (a piece of metal ore, perhaps).

NASA discovers new black hole in Milky Way



Washington: NASA's Swift satellite has found evidence of the presence of a previously unknown stellar-mass black hole in our Milky Way galaxy.

Named Swift J1745-26 after the coordinates of its sky position, the nova is located a few degrees from the centre of our galaxy towards the constellation Sagittarius, NASA said.

While astronomers do not know its precise distance, they think the object resides about 20,000 to 30,000 light-years away in the galaxy's inner region.

Helix Nebula Photo: Giant 'Eye' In Space Spotted By NASA Telescopes



A pair of NASA space telescopes have captured a spectacular new photo of the Helix Nebula, a glowing celestial vision that resembles a giant cosmic eye.
The Helix Nebula (also known as NGC 7293) represents a dying star known as aplanetary nebula. The new picture, released Wednesday (Oct. 3), combines data from NASA's Spitzer Space Telescope, which observes in long-wavelength infrared light, and the Galaxy Evolution Explorer (GALEX), which picked out the short-wavelength ultraviolet light coming from the object.
The Helix Nebula is located about 650 light-years from Earth in the constellation of Aquarius. It provides a sneak peak at the future of our own sun, which is expected to turn into a planetary nebula in about 5 billion years.

Highly charged – the US Navy's electromagnetic railgun programme


Railguns consist of two parallel metal rails, between which a projectile held in an armature is loaded, completing a circuit between them. A massive electrical current of the order of one million amperes is applied, creating an electromagnetic field, which in turn produces a force that accelerates the projectile along the rails.
A railgun offers a number of potential advantages over traditional explosive projectile weapons. The accelerating force is applied to the projectile for the entire time the projectile is between the rails of the launch device, as opposed to explosive forces which, however powerful, have a limited duration.

Washington confirms Chinese hack attack on White House computer

clam666 writes"White House sources partly confirmed an alarming report that U.S. government computers — reportedly including systems used by the military for nuclear commands — were breached by Chinese hackers.

I mostly submitted it because I just loved the phrase "The attack originated in the form of a spear phish, which involves a spoofed inbound email with either a link to a malicious website or a weaponized document attachment such as a .pdf, Microsoft Excel file or Word document"

Damn those weaponized Excel files."

Sun Shock Waves: New Theory Could Predict When Planets Form


Our solar system's planets may have formed at differing times, determined by shock waves flowing from the young sun, one astronomer suggests.
This theory posits that Earth is one of the youngest planets in the solar system, along with Mercury, Venus and Mars.
In a new paper, Tagir Abdylmyanov, an associate professor from Kazan State Power Engineering University in Russia, describes his idea and suggests it presents a possible new way of predicting where planets will form in young star systems.

US Military Designates Julian Assange an "Enemy of State"

First time accepted submitter Cute and Cuddly writes in with some new Julian Assange news."The U.S. military has designated Julian Assange and WikiLeaks as enemies of the United States — the same legal category as the al-Qaeda terrorist network and the Taliban insurgency.

Bangladesh vows to protect Buddhists after Facebook photo attacks


Hundreds of Buddhists who fled their southern Bangladesh villages in the wake of attacks by Muslims started returning home Monday amid heightened security and more than 160 arrests.
The Buddhists moved to safety after an overnight weekend attack in which thousands of Bangladeshi Muslims burned at least 10 Buddhist temples and 40 homes in anger over a Facebook photo of a burned Quran.
Army soldiers, paramilitary border guards and police were deployed, and the government has banned all public gatherings in the troubled areas near the southern border with Myanmar, said Lt. Col. Jaed Hossain, a military commander who was helping to install tents for displaced Buddhists.
"They are coming back. We are giving them protection," Hossain said at Merunglua village in the coastal district of Cox's Bazar on Monday.
