United States swimmer Michael Phelps has been banned from competition and his training stipend revoked for three months by USA Swimming after Phelps was photographed smoking from a glass pipe, often used for smoking cannabis. The picture was published last Sunday by British tabloid News of the World.

USA Swimming, which is the governing body of swimming in the United States, however said that no “anti-doping” rules had been violated.

“This is not a situation where any anti-doping rule was violated, but we decided to send a strong message to Michael because he disappointed so many people, particularly the hundreds of thousands of USA Swimming member kids who look up to him as a role model and a hero,” it stated. “Michael has voluntarily accepted this reprimand and has committed to earn back our trust.”

The suspension will end in time for Phelps to train for the US Championships, which are to be held on the 7th of July.

Phelps has also lost sponsor Kellogg, who said that it would not renew its deal with the swimmer next month.

Phelps won a record eight gold medals at the 2008 Olympic Games in Beijing last year, and has since become one of the world’s most famous athletes.

Following the Pilkhana massacre which occurred February 25 and 26 leaving 74 dead and the inferno at the Bashundhara City shopping mall complex March 13 leaving seven dead, Prime Minister Sheikh Hasina said security measures are being tightened countrywide across Bangladesh.

Fire drills will be enacted at all key-point installations (KPI). Fire fighting systems will be examined by the fire brigade and the public works department (PWD) to ensure functionality. Security measures will be enhanced supplementing areas under private security such as at the Bashundhara City Complex.

The Fire Service and Civil Defence Department requires modernization and needs new equipment to fight fires past the sixth floor of buildings. The Fire Brigade says it needs turntable ladders, snorkels, foam-tenders, lighting units, emergency tenders, fireproof uniforms, and rescue ropes for fire fighting and rescue operations. Transportation to fires is also an issue due to narrow roads, low electrical wires and congestion.

The Bangladesh National Building Code requires fire fighting equipment installed in buildings over seven floors. This code is to be monitored by authorities to ensure compliance with the new guidelines and to make sure buildings are being maintained.

The Bashundhara City Complex opened Monday for shoppers two days after Friday’s blaze. A probe is underway to determine the cause of the fire and to assess structural damage.

Loss of life was minimized as the blaze broke out on a Friday, the beginning of the weekend in Bangladesh, so offices in the upper floors were empty. The lower eight floors are used for shopping and the upper floors are all Bashundhara Group offices.

The mall is valued at Tk 7.0 billion (US$100 million). It is not known if the complex is covered by fire insurance.

It is estimated that it will take over two years to rebuild the area damaged by flames which were burned down to a skeleton. Bashundhara City’s technical advisor, Latifur Rahman, estimated damages at Tk 2.0 billion (US$29m).

Only one television cameraman has been allowed in to film the burnt area. None of the 2,500 shops, cinemas or cafes were burnt by the inferno. The seventh and eighth floors still experience smoke damage, and there was water damage to merchandise.

A three member committee is currently investigating the cause of the fire which will consist of Iqbal Khan Chowdhury, joint secretary of the ministry, representatives of the police, IGP Noor Muhammad, and fire brigade, Director General Abu Nayeem Md Shahidullah. The committee is required to report within the week with their findings. The forensics department is also sifting through the burnt remains.

The Dhaka Chamber of Commerce and Industries has also formed a committee which has begun interviewing witnesses and recording their testimony alongside the government committee.

It has been discovered that 150 closed circuit cameras were not being used when the fire started. Another mystery is why the mall fire fighting system has been found unused.

“In the shopping mall there is an ultra-technology elevator which runs even without electricity but we have found that locked,” Iqbal Khan Chowdhury, joint secretary (Police) of the home ministry, said. “Why the fire burnt so fiercely is a matter to think. We have to see if there was any incendiary substance there. These matters seem to be mysterious.”

Mall management has been asked to submit substances and items which would have been in the upper floors when the fire started. The fire erupted on the 17th floor and spread quickly to the two floors above and engulfed the three floors below. The aerial ladders belonging to the Fire Service and Civil Defence reached as high as the 13th floor of the 21-storey building.

Videos have been sent to the United States (US) for examination to assist in determining the cause of the fire and to help in the damage assessment. Experts from the US are expected to arrive soon.

Firefighters were brought to the rooftop of the 20-storey tower by helicopter. The only fatality in this operation was Baki Billa, a firefighter of Bashundhara City firefighting department, who fell when climbing down a rope from a helicopter to the roof of the building. Three other firefighters made the transition safely. At this same time, the chief security officer was safely rescued by the Bangladesh Air Force helicopter, a Bell 212. Six security officers of the complex also lost their lives.

A Pembroke Pines, Florida teenager killed himself Wednesday, November 19, while broadcasting on the live video site Justin.tv. After making suicide threats and being encouraged by Justin.tv viewers and Bodybuilding.com forum members, Abraham K. Biggs, 19, committed suicide by taking an overdose of opiates and benzodiazepine, which had been prescribed for his bipolar disorder.

Biggs first began blogging about his planned suicide 12 hours before the actual event. He died after taking pills and lying on the bed in front of the webcam. After the broadcast, viewers who apparently thought it was a hoax posted messages such as “OMG”, “LOL”, and “hahahah”.

Hours later, after being alerted by viewers who had noticed that Biggs had stopped breathing, law enforcement and paramedics arrived, discovered his body, and covered the camera. The Broward County Medical Examiner’s Office has reportedly confirmed Biggs’ death.

According to Montana Miller of the Bowling Green State University, the circumstances of this case were not shocking: “If it’s not recorded or documented, then it doesn’t even seem worthwhile. For today’s generation it might seem, ‘What’s the point of doing it if everyone isn’t going to see it?'”

Biggs’ sister Rosalind was angry that neither the website nor its viewers reacted soon enough to save him. “They got hits, they got viewers, nothing happened for hours,” she said. She described him as “very happy” and “friendly and outgoing.” “On a normal day, you couldn’t really tell that he got as low as he did.” However, he did have relationship problems with his girlfriend, according to a friend.

Mental health professionals have warned about the possibility that other mentally troubled people would copy his actions. According to Dr. David Shaffer of Columbia University, “Any video showing it as heroic or romantic or glamorous could reduce the anxiety people might feel about suicide. It becomes a respectable behavior and lowers the threshold of suicide.” He and other psychiatrists recommend that potentially suicidal teens talk to others and “tell what’s going on.”

At least 20 people have died and 20 more are injured after a partially constructed flyover (overpass) in Hyderabad, India collapsed onto traffic.

The disaster occurred at the Panjagutta junction, near Nagarjuna Circle. Two large concrete sections dropped onto oncoming cars and motorised rickshaws, damaging several severely.

A large emergency effort was immediately activated, but experienced severe difficulties in reaching the site due to congested traffic resulting from the collapse. Ambulances from the 108 EMRI Service and Appollo Hospitals attended the scene, and rushed the injured to a variety of nearby hospitals. All the region’s major hospitals, particularly the nearby Nizam Institute of Medical Sciences, have placed their medical staff on emergency alert. Rescuers are now using cranes and cutting equipment in an effort to reach anyone who may still be trapped. It is expected that the death toll could rise further as many vehicles remain trapped under tons of debris.

Various politicians also attended the scene, including the local district collector, Chief Minister of Andhra Pradesh Dr. YS Rajasekhara Reddy, Senior Congress Leader and MLA from Khairathabad P Janardhan Reddy and several other ministers.

Police have asked both the public and the press to keep away from the area, in order to prevent further collapse of the unstable structure. Preliminary investigations suggest the flyover had been been poorly constructed. The construction project had been carried out by leading contractor Gammon India Limited. It had been delayed, the original foundations having been built in 2005. After a successful request by the company to have the deadline for the project extended, work was slated to cease in November of this year, with the flyover entering operation by December. It is believed heavy rains in the area a few hours prior to the collapse may have contributed to the disaster.

On Monday, at 10.14 pm UTC, the Wikimedia server cluster experienced a total power failure, taking down Wikipedia, Wikinews, and all other Wikimedia websites.

The servers are housed in a colocation facility (colo) in Tampa, Florida, USA. They occupy two racks, with each rack receiving electricity from two independent supplies. However, both supplies have circuit-breakers in them, and both opened at the same time, leading to a total power failure. All computers immediately went down. It’s normal for fire safety regulations to prohibit uninterruptible power supplies in colos, with the colo providing its own UPS and generator instead. The circuit breakers were on the computer side of this emergency power system, so none of the computers continued to receive power to survive the breaker trip or shut down safely.

The actual reason why the circuit breakers tripped is currently unknown.

When power was restored, it was discovered that most of the MySQL databases that store the data which makes up Wikipedia et al had been corrupted. The main database and the four slaves had all damaged the data on their hard disk drives beyond the ability of the auto-correction to repair. Only one copy survived safely, on a machine that is used for report generation and maintenance tasks, which remained 31 hours backlogged while catching up after an unusually heavy update load during the previous week.

Volunteer Wikimedia engineers worked through the night rebuilding the databases from the sole good copy onto the other servers. The Wikipedia database is over 180Gb in size, making the copying process last 1.5 – 2 hours for every server it was performed upon.

Regular back-ups of the database of Wikipedia projects are maintained – the encyclopedia in its entirety was not at risk. The last database download was made on February 9; all edits since then could only have been laboriously rebuilt from logs and recovered from the damaged database requiring much more time and effort.

Limited read-only service was established late Tuesday afternoon, with editing becoming possible 24 hours after the power failure. Final repairs continue now, as well as upgrades to prevent similar issues in the future. Server-intensive features, such as categories and ‘watchlists’ that display recent changes to selected articles to registered users, remain disabled to ease the load on the recovering systems.

The process which led to the damage originated with the operating system, disk controllers, or hard drives failing to flush the data correctly.

If the power to a database server is cut mid-write, the database may be corrupted and unreadable, however the operating system, hardware, and software are designed to make this very unlikely. In a previous incident in 2004 power was also lost to a server but the database was undamaged.

To avoid such damage, each database server saves a copy of an edit to be applied to the database on a separate storage system before making the actual update to the database itself. This so-called ‘write-ahead logging’ should ensure that in the event of a system crash, the database can be rebuilt from a ‘last-good’ state by replaying the edits saved in the log.

Earlier this year popular blogging site LiveJournal suffered a similar power failure when another customer at their colocation facility pressed an Emergency Power Off button, intended for use only by firefighters. The company suffered database corruption similar to that seen at Wikimedia.

LiveJournal are now fitting UPS to their servers to ensure that they have time to shut down safely in the event of a power failure. Wikimedia was said to be investigating the possibility of fitting similar equipment at the time of this failure.

Several pundits have suggested that the use of another database, such as the proprietary database Oracle or the free PostgreSQL, would have avoided the database corruption seen at the server cluster. A post-mortem of the incident show the failure was in the operating system, or the hardware, or some combination of the two. LiveJournal, which also uses MySQL, reported similar database corruption after their power cut.

The Wikimedia foundation only allows the use of free software on its systems, and future versions of the Mediawiki software will support the PostgreSQL database.

Users are reminded that during times of system failure or excessive demand, they can still search Wikipedia using Google. The articles may be viewed using Google’s cache.

On Friday, code hosting and sharing website GitHub blocked the public access to youtube-dl, a software which can download videos from the internet via the command-line. The blockade came after GitHub received a Digital Millennium Copyright Act (DMCA) take-down notice from the Recording Industry Association of America (RIAA). After stripping the metadata from the notice, GitHub published the take-down notice on their site.

Initially started in July 2008 by Ricardo Garcia, youtube-dl is a script written in Python which can download videos from multiple websites including YouTube, LiveLeak and Vimeo. youtube-dl is a FLOSS software and is under public domain. Currently, the repository on GitHub is locked for viewers other than maintainers of the project.

RIAA’s DMCA notice alleged the script’s purpose of existence was to “circumvent the technological protection measures used by authorized streaming services such as YouTube” and “reproduce and distribute music videos and sound recordings owned by our member companies without authorization for such use”.

youtube-dl has multiple unit tests in its source code, which test whether the software works in different circumstances or not. Some of the tests include checking if the script can download Creative Commons licensed videos, videos which did not have square pixels, videos with no age restriction, “offensive to some audiences” per YouTube community and age-restricted videos. One of the tests included the URL of some copyrighted songs. Citing this test, RIAA’s take-down notice claimed “comments in the youtube-dl source code make clear that the source code was designed and is marketed for the purpose of circumventing YouTube’s technological measures”.

RIAA’s notice published by GitHub alleged violation of 17 U.S. Code § 1201 Circumvention of copyright protection systems which says “No person shall circumvent a technological measure that effectively controls access to a work protected under this title”. RIAA listed a number of forks of youtube-dl and requested GitHub via the notice they all be made inaccessible.

The notice did not list any incident of anyone using youtube-dl to download or share copyrighted material, nor mention any damages that actually occurred. Unremarked by the notice, YouTube allows videos to be licensed under a Creative Commons Attribution license. When a copyright holder chooses to release their work, be it a photograph, a video, or audio, under a Creative Commons Attribution (CC BY) license, they allow everyone to freely own, share or modify the work as long as the reusers properly attribute the author of the work. YouTube also hosts many audio and video recordings in the public domain which can be used for any purpose without any restrictions.

youtube-dl is used by thousands of people around the world. Multiple Creative Commons-licensed and public domain videos on Wikimedia Commons are uploaded via a tool called video2commons, which relies on youtube-dl to download media. youtube-dl also lets users download videos from LiveLeak — a video-sharing platform for citizen journalism. Videos downloaded using youtube-dl are also used for the purpose of fair use, or for evidence.

youtube-dl comes with a small JavaScript interpreter where it acts as a web-browser would behave while receiving video data from the server. The script has “extractors” for various websites to handle videos from different sources. Whenever something is displayed on the user’s screen, the device has a copy of that content. Web browsers “download” data while surfing the web, though most of it is not persistent on the device. It is possible to download copyrighted photos by using a web-browser. The way the world wide web works, there are no technological prevention measures to prevent recording and sharing of content such as RIAA talks about in the notice. Photos and texts can be downloaded by taking screenshots, videos by screen recording tools, and audio by recording on a tape if not an audio recording software.

Multiple users expressed their disappointment on Twitter and Internet Relay Chat. One of the users said “this is yet another example of why we should use git as it was intended, as a distributed network, rather than rely on one single proprietary server”. Git is decentralised version-tracking software which is used by a large number of software companies and projects. It is possible to host one’s own git server for software development. While Microsoft’s GitHub is a centralised git server, development of software using git does not require a GitHub account.

Soon after the public access to the repository was locked, multiple users started sharing the source code via self-hosted git servers, Tor sites and via the Torrent protocol leading to a Streisand effect. Streisand effect is when a measure to censor information causes further spread of that information. The binary files of the software are still available on its website for users to download. Some people came up with esoteric ways to share the source code, by converting the compressed code into photographs and providing shell commands to convert to the source code.

GitHub’s DMCA repository, where the takedown notice was published for public viewing, was subject to contant vandalism from multiple GitHub users. One user submitted a pull request, merging the source code of youtube-dl along with the DMCA repository. This enabled users to view youtube-dl’s source code from within the DMCA repository, provided they know the commit id.

The Electronic Frontier Foundation said on Twitter “Youtube-dl is a legitimate tool with a world of a lawful uses. Demanding its removal from Github is a disappointing and counterproductive move by the RIAA.” Richard Stallman, the founder of the Free Software Foundation, has been highly critical of DRM (digital rights management, the subject of the DMCA) for many years now.

Wikinews reached out to Sergey M?, one of the maintainers of youtube-dl script, however Sergey said he “won’t give any comments at this time”. Later, he shared an update on the IRC channel. Sergey said, “they require complete removal of so called YouTube’s rolling cipher implementation […] GitHub requires in order to reinstate the repo […] under this conditions I could reinstate it in Saturday/Sunday already but this is an unsatisfactory outcome”. He also said, “I can’t guarantee whether [or] not we will bend over them considering the situation with @phihag [Philipp Hagemeister] but we’ll see soon what we can do in order to keep the max we have and mitigate potential legal issues at the same time”.

EFF is yet to respond to Wikinews queries. Wikinews also reached out to Philipp Hagemeister, a former maintainer and contributor of the youtube-dl project to discuss this takedown.

When did you get to know about the takedown notice and what were your initial reactions?

((Philipp Hagemeister)) I saw the takedown notice along with anyone else, on reddit. Since I am no longer involved with the youtube-dl project (except for occasional contributions, my maintainership ended in 2016), I don’t know any details.

((RS)) Does YouTube implement DRM for videos not under Creative Commons license, and if so, how does youtube-dl bypass it? Could you please elaborate the procedure?

((Philipp Hagemeister)) YouTube implements DRM for YouTube Movies. youtube-dl does not support those.

YouTube has multiple non-DRM video delivery protocols. I’m not up to date about specifics; my last dabbling in this was in 2015.

One of these protocols is described here. YouTube uses JavaScript to compute parts of the URLs. youtube-dl executes this JavaScript, just like a web browser.

((WN)) Could you also explain in brief how youtube-dl functions, and how the maintainers had intended it to be used?

((Philipp Hagemeister)) youtube-dl downloads and plays videos and music, just like any other web browser, from over 1000 different services. Its uses are varied: It enables video playback on many devices (e.g. Raspberry Pi) where the video services don’t work properly, it makes high-quality video playable for people with a bad or no Internet connection, it enables disabled users to use tools to play videos, and it is used for archival and research.

((WN)) What do you think of the DMCA notice?

((Philipp Hagemeister)) I think it is not warranted because youtube-dl is entirely legal. As the DMCA notice has no effect for me personally, I’m not really the right person to address it.

((WN)) Why were the copyrighted tests in the source code? Could they be replaced?

((Philipp Hagemeister)) I’m not sure why, but my guess is that users requested support for these videos and thus they were added as test cases. They can be removed trivially, without losing any function of youtube-dl.

((WN)) Are you aware Electronic Frontier Foundation said it was a “disappointing and counterproductive move”? What do you think should be the next steps?

((Philipp Hagemeister)) Yes, and I concur. I’m no longer involved in the project. If I were, I would probably just remove the test cases, block these music videos (RIAA is not worth the trouble for me, that can be done by other projects), and get the project back online.I understand people who think differently.

Just two weeks after China sent global markets into a tumble, growing worries about sub-prime mortgage lenders in the United States are sending jitters through stock exchanges around the globe. The three major US stock market indices each fell two percent from Monday’s closing price, marking the second-biggest loss of 2007. London’s FTSE 100, Paris’ CAC 40 and Frankfurt’s DAX 30 indices each closed down more than 1 percent.

As the Mortgage Bankers Association reported that late payments on mortgages and home foreclosures in the US homes rose in the fourth quarter to their highest level in years, investors are concerned that not only US banks but also multi-national banks around the globe could have exposure.

More than two dozen sub-prime lenders have closed or sold operations as defaults on those mortgages have risen. “The delinquencies and defaults have started to soar,” said Nicolas Retsinas, director of Housing Studies at Harvard University. “A lot of these lenders started to make loans and lost track of some of the fundamentals.”

New Century Financial Corporation, the second largest sub-prime lender in the US, has recently revealed that its creditors were no longer providing funds and, further, it has become subject of an SEC investigation. The New York Stock Exchange has said it will delist New Century. Accredited Home Loan Lending, another major sub-prime mortgage specialist, said it was seeking fresh capital and waivers on its lending covenants.

Sub-prime lenders provide mortgages to people who do not qualify for loans from mainstream lenders, typically due to their credit histories. The lenders then bundle these mortgages as collateral for loans that they obtain from other financing firms, such as GMAC. Such firms can then repackage these loans and sell them as mortgage-backed securities. These securities may end up in the hands of major multi-national banks such as Citibank, HSBC, and Commerzbank. Each level of lending assumes a level of financial risk, but trouble can arise when the risk tolerances are exceeded. If too many homeowners default on their mortgages, the sub-prime lender can end up defaulting. If too many of these lenders default, as it is feared may be happening now, the defaults can cascade upward. While no one is predicting major bank failures at this point, it is feared that their profits could be hurt.
