Yes, but pinpointing the problem in GCC source code is another story.

Try fixing a bug in an OSS project sometimes, if you haven't. It can take ages to familiarize yourself with the project to be able to pinpoint the problem.

Linus Torvalds: "GCC 4.9.0 Seems To Be Terminally Broken"

jones_supa Re:Surprise, surprise... (419 comments)

GCC is open source. If Linus is such a great expert on the issues with it then why isn't he fixing them? Probably because he doesn't have the skills.

You can't just go and fix every program, even if they are open source. It takes a lot of time to familiarize one with the code base. That is probably limiting Linus here too. His bug report is very precise, and that will greatly ease the job of the GCC developer who actually fixes the bug.

Linus Torvalds: "GCC 4.9.0 Seems To Be Terminally Broken"

jones_supa Re:Linux, a miracle (419 comments)

The problem with Linux and OSS in general is that these kind of weird problems can pop up any time and are partly the responsibility of the general public to test and report. With Windows and Mac, the extensive quality assurance catches a lot of this stuff and I do not have to worry about it in the first place. I am not saying that even commercial OSs are perfect, but they are much more smooth sailing. I still share your argument that with closed software, it is almost impossible to reach the engineers if there is a problem.

Another worrying thing which Linus says there is:

"The problem is that these things are a bitch to debug - they turn into these completely impossible kernel oopses or corruption, and we were just very lucky that this one case happened to be repeatable and pinpoint for two people. Are there others? We have no way of knowing.."

jones_supa Re:Surprise, surprise... (419 comments)

These days I interpret Linus' "meltdowns" just as some funny nerd rage. He uses that technique to strongly underline the importance of his point, it's never real anger. Often there's a dash of humor in the mix, such as in this case the comment "that compiler shouldn't have been allowed to graduate from kindergarten".

Can you explain what is the %rbp, and why are its offsets negative? If I set values 1, 2, 3, 4 to a bunch of variables, I get this assembly code:

movl $1, -4(%rbp)

Ask Slashdot: Where Do You Get (or Share) News About Open Source Projects?

jones_supa Re:irc://irc.geekshed.net/jupiterbroadcasting (82 comments)

IRC should be steamrolled and a better system brought to replace it.

- It does not come with encryption
- Netsplits are handled crudely
- A lot of functionality (such as nickname registration or channel ownership) is not in the spec and is handled by hacky bots or modified servers
- It unnecessarily exposes the network layer to the user
- It can be confusing and overly technical to a newbie

Ask Slashdot: Where Do You Get (or Share) News About Open Source Projects?

jones_supa Re:Google? (82 comments)

Yeah, but Slashdot has its own ideologies:

- Linux and Apple good, Microsoft bad
- copyright assertion bad, piracy good (since digital stuff was meant to be free). Big exception: GPL violations must be vigorously prosecuted
- patents are bad (this one I mostly agree with)
- privacy violation by the government for security is totalitarian and alarming, similar techniques by Internet companies is a necessary evil (as a business model)
- H1-Bs and offshoring of US/Western European jobs to developing companies bad
- technologies or companies promising to make programming and/or system administration dramatically cheaper and easier = quackery
etc

Heh! I might as well add some:

- IPv6 is the best thing since sliced bread
- NAT is always terrible and one must run public IP addresses and a real firewall instead
- The Ribbon widget is awful
- Ubuntu Unity is crap
- Daylight saving time is a bad idea
- Internet Explorer is a buggy and non-standards-compliant web browser
- Everything must be open source and run the Linux kernel

Greenpeace: Amazon Fire Burns More Coal and Gas Than It Should

It does not depend on that, because then the amount of copies stored on SD cards would also be higher or lower.

jones_supa Re:Hipsterism at its finest (worst?) (269 comments)

It's more efficient to store 1 file on a central hard drive than store millions of redundant copies on millions of SD cards.

Transmitting a copy of that 1 file every time when it is accessed consumes enormous amount of energy.

Soccer Superstar Plays With Very Low Brain Activity

Should be no surprise to anyone who's every played a videogame: he's in "flow" mode.

How do you know that it is the same thing?

Which raises the question: how is this news for nerds?

I thought that how the brain works is quite nerdy topic. That is why I submitted this. Would you like to see less news like this in the future?

Soccer Superstar Plays With Very Low Brain Activity

jones_supa jones_supa writes  |  2 days ago

jones_supa (887896) writes "Brazilian superstar Neymar's (Neymar da Silva Santos Júnior) brain activity while dancing past opponents is less than 10 per cent the level of amateur players, suggesting he plays as if on "auto-pilot", according to Japanese neurologists Eiichi Naito and Satoshi Hirose. The findings were published in the Swiss journal Frontiers in Human Neuroscience following a series of motor skills tests carried out on the 22-year-old Neymar and several other athletes in Barcelona in February this year. Three Spanish second-division footballers and two top-level swimmers were also subjected to the same tests. Researcher Naito told Japan's Mainichi Shimbun newspaper: "Reduced brain activity means less burden which allows [the player] to perform many complex movements at once. We believe this gives him the ability to execute his various shimmies." In the research paper Naito concluded that the test results "provide valuable evidence that the football brain of Neymar recruits very limited neural resources in the motor-cortical foot regions during foot movements"."

As she reveals in her cheerful announcement, Sara will be first Finnish artist to sign a deal with an American major record label. Forsberg's record will be released by the major record company Capitol Records (part of Universal Music Group), her managers Jere Hietala and Johannes Ylinen report. The contract was made in Los Angeles in early April, but thus far the matter has been kept secret. The 20-year-old Pietarsaari-native Forsberg became a YouTube hit early this year. Her most popular video is called What Languages Sound Like to Foreigners, where Forsberg pretends to speak different languages, even though she speaks complete gibberish in German, French and Japanese."

GOG.com Begins Selling Linux Games

Back then the planned date to go live was some time around this autumn, but things have been rolling so smoothly that they can start Linux operations ahead the schedule, more precisely right now. The site infrastructure is ready with 50 Linux titles — classic and new — prepared for distribution. The full list of Linux games can be found from the official announcement. If you happen to have some of them purchased already, you own the Linux version too. GOG.com will provide distro-independent compressed tape archives (tar.gz) and Debian format packages (deb), with Ubuntu and Mint being the officially supported operating systems."

Nokia to Buy Mobile Phone Base Station Business from Panasonic

jones_supa jones_supa writes  |  about a week ago

jones_supa (887896) writes "Panasonic has apparently reached a basic agreement to sell its cellphone base station business to Nokia. Panasonic will part with the base station operations of subsidiary Panasonic System Networks, which include wireless control systems for communications equipment. The transaction's value is likely to be in the billions of yen. According to MCA, a Tokyo-based mobile industry research company, Japan's base station market was worth about 260 billion yen in fiscal year 2013. Nokia is the market leader with a 26% share. Since 2007, the Finnish company has had a partnership with Panasonic to develop products for NTT Docomo's LTE high-speed telecommunications services. Now Nokia intends to capitalize on Panasonic's ties with NTT Docomo to further expand its market share in Japan."

Michael J. Fox Donates $2M USD to a Finnish Medicine Company

jones_supa jones_supa writes  |  about three weeks ago

jones_supa (887896) writes "Biotie Therapies from Turku, Finland has signed a USD 2 million research contract with The Michael J. Fox Foundation (MJFF) to investigate SYN120 in Parkinson's disease patients with dementia. SYN120 is a dual antagonist of 5-HT6 and 5-HT2a receptors and these two distinct modes of action could result in a unique therapeutic profile for SYN120 combining pro-cognitive and antipsychotic activities. MJFF will fund an 80 patient, Phase 2a, randomized, double-blind, placebo-controlled trial of 16 weeks duration in patients with Parkinson's disease dementia. In addition to assessing safety and tolerability, the main focus of the trial will be to establish efficacy of SYN120 on cognition using the Cognitive Drug Research (CDR) Computerized Cognition Battery as the primary efficacy endpoint. This trial, which is expected to begin in H2 2014, will be conducted by the Parkinson Study Group (PSG) at approximately 10 US sites specializing in cognitive dysfunction in Parkinson's disease."

Operating System U Aims For The Year of Linux Desktop

jones_supa jones_supa writes  |  about three weeks ago

jones_supa (887896) writes "A new Linux distribution under development is among the latest dreaming of commercial success in hopes of finally conquering the Linux desktop and having their OS pre-installed on systems being sold in brick and mortar stores. Operating System U is to be based off Arch Linux, run a modified version of the MATE Desktop Environment, and will use Wayland from the get-go. In the features page some criticism is given how buggy both MATE and X.org currently are and how better choices are needed. MATE shall also get a component they call "Startlight", which pairs the Windows Start Button with Apple's Spotlight. To make all of this a reality, the team is going to try a Kickstarter campaign later this month to raise $150,000 USD for the development of Operating System U, plus they're trying to rely on external funding as well. It is questionable whether that funding level will go very far for a team of ten with very lofty goals. Canonical has invested millions and employing hundreds of developers and still hasn't completely cracked the Linux desktop."

Fabien Cousteau Beats Grandfather's Underwater Record

jones_supa jones_supa writes  |  about three weeks ago

jones_supa (887896) writes "Fabien Cousteau and a team of aquanauts were together on land for the first time in 31 days on Wednesday to celebrate the end of his record-breaking underwater stay. Mission 31 ran just one day longer than the underwater adventure that inspired it – one which was lead by Cousteau's grandfather, the renowned oceanographer Jacques-Yves Cousteau. The point of the recent mission was to spend as much time as possible outside of the vessel to conduct experiments and become more attuned to the ocean environment. Fabien, who only saw daylight for the first time in 31 days five hours before speaking to the media, said some of his favorite experiences underwater included "making friends with a porkfish" and "looking out the window and seeing sharks or a barracuda". Cousteau said he hoped his 2014 mission would increase support for ocean conservation, a message his grandfather helped bring to the public, along with providing a platform for several climate change studies."

Russia Moves from Summer Time to Standard Time

jones_supa jones_supa writes  |  about a month ago

jones_supa (887896) writes "Russia's legislature, often accused of metaphorically turning back the clock, has decided to do it literally – abandoning the policy of keeping the country on daylight-saving time all year. The 2011 move to impose permanent "summer time" in 2011 was one of the most memorable and least popular initiatives of Dmitry Medvedev's presidency. It forced tens of millions to travel to their jobs in pitch darkness during the winter. In the depths of December, the sun doesn't clear the horizon in Moscow until 10am. The State Duma, the lower house of parliament, voted 442-1 on Tuesday to return to standard time this autumn and stay there all year."

Chimpanzees Develop A Grass-in-ear Fashion Trend

jones_supa jones_supa writes  |  about a month ago

jones_supa (887896) writes "Just in time for this year's primate-starring film event, the Dawn of the Planet of the Apes, comes news from Zambia that also chimpanzees seem to form fashion trends. The behaviour appears to be "non-adaptive", i.e., motivated by frivolous rather than functional reasons. Dutch primate specialist Edwin van Leeuwen describes it as "quite unique". He first spotted the trend-setting chimp in 2010 when Julie, an elderly female, repeatedly popped long pieces of grass in her ear and left it there for several hours. The quirky idea was adopted by seven other chimps in her troop, who still continue to do it after her death. This may be the first fashion trend documented in the animal world, according to the study published recently in science journal Animal Cognition."

Experimenting With Motivational Passwords

jones_supa jones_supa writes  |  about a month ago

jones_supa (887896) writes "At Mauricio Estrella's workplace, the Microsoft Exchange server is configured to ask thousands of employees around the planet to change their passwords every 30 days. Mauricio often approached the situation with an angry grandpa voice in his head: "The damn password has expired." This input field with a pulsating cursor, waiting for him to type a password that he will have to re-enter for the next 30 days. Many times during the day. Then a lightbulb went on inside his head: "I'm gonna use a password to change my life." His passwords became little motivational snippets, every one being a condensed phrase for a goal or dream. He set his first motivational password to be Save4trip@thailand. Guess where he went 3 months later. Mauricio kept doing this and found the method to work surprisingly consistently for various goals, which he lists in his blog post. To summarize, this might be one way to make your passwords a bit more fun and to remind about good habits. Just for added security he recommends scrambling the passwords a bit more than in his examples."

KeyStore Vulnerability Affects 86% of Android Devices

jones_supa jones_supa writes  |  about a month ago

jones_supa (887896) writes "IBM security researchers have published an advisory about an Android vulnerability that may allow attackers to obtain highly sensitive credentials, such as cryptographic keys for some banking services and virtual private networks, and PINs or patterns used to unlock vulnerable devices. It is estimated that the flaw affects 86 percent of Android devices. Android KeyStore has a little bug where the encode_key() routine that is called by encode_key_for_uid() can overflow the filename text buffer, because bounds checking is absent. The advisory says that Google has patched only version 4.4 of Android. There are several technical hurdles an attacker must overcome to successfully perform a stack overflow on Android, as these systems are fortified with modern NX and ASLR protections. The vulnerability is still considered to be serious, as it resides in one of the most sensitive resources of the operating system."

YouTube Introduces 60 fps Video Support

As the another new feature, YouTube is also offering direct funding support for content creators — name-checking sites like Kickstarter and Patreon — and is allowing fans to "contribute money to support your channel at any time, for any reason." Adding the icing on the cake, the website has also a number of other random little features planned, including viewer-contributed subtitles, a library of sound effects and new interactive info cards."

MH370 Was On Autopilot When It Crashed

jones_supa jones_supa writes  |  about a month ago

jones_supa (887896) writes "The Australian Transport Safety Bureau’s Chief Commissioner Martin Dolan explained that MH370’s “highest probability flight path” was a straight course such as one flown by an aircraft on autopilot. Authorities have not been able to assess the exact point at which autopilot was turned on but believe the Boeing 777 was operating on autopilot from the 1st arc — shortly after MH370 turned south past the tip of Sumatra — to the 7th arc in the southern Indian Ocean. The revelation that autopilot was activated raises further suspicion the plane’s disappearance was a mass atrocity committed by either the captain or copilot of the plane. The theory is also consistent with reports that an official police investigation into the mystery identified the captain as the prime suspect if it is proven human intervention was involved. As the result, the hunt for MH370 will now return near to the original search area. An expert satellite working group has reviewed all existing information in order to define a search zone of up to 60,000 square kilometres along the arc in the southern Indian Ocean. The new area is around 1,800 kilometres west of Perth and had previously been subject to an aerial search, which found no debris. This area shall now be scoured underwater."

Improvements The Linux Desktop Needs

jones_supa jones_supa writes  |  about a month ago

jones_supa (887896) writes "In the last fifteen years, the Linux desktop has gone from a collection of marginally adequate solutions to an unparalleled source of innovation and choice. Many of its standard features are either unavailable in Windows, or else available only as a proprietary extension. As a result, using Linux is increasingly not only a matter of principle, but of preference as well. Yet, despite this progress, gaps remain. Some are missing features, others missing features, and still others pie-in-the sky extras that could be easily implemented to extend the desktop metaphor without straining users' tolerance of change. DataMation begins the discussion by throwing some suggestions on the table: easy e-mail encryption, thumbnails for virtual workspaces, more workable menus, professional and affordable video editor, a proper document processor, color-coded title bars and, icon fences. There's probably dozens of other unspoken ideas out there, so what improvements to the Linux desktop would you add to the list?"

Eskimo Diet Lacks Support for Better Cardiovascular Health

jones_supa jones_supa writes  |  about a month and a half ago

jones_supa (887896) writes "Monthly Prescribing Reference reports that the "Eskimo diet" hypothesis, suggested as a factor in the alleged low incidence of coronary artery disease (CAD) in Greenland Eskimos, seems not to be supported in the literature, according to a metastudy published in the Canadian Journal of Cardiology. Researchers found that only one study directly assessed the prevalence of CAD or CAD risk factors, and that study showed that CAD morbidity was similar among Inuit and American and European populations. In most studies, the prevalence of CAD was similar for Greenland Eskimos and Canadian and Alaskan Inuit and for non-Eskimo populations. The original studies from the 1970s that formed the basis of the supposed cardioprotective effect of the Eskimo diet did not examine the prevalence of CAD. 'The totality of reviewed evidence leads us to the conclusion that Eskimos have a similar prevalence of CAD as non-Eskimo populations,' the authors write. 'To date, more than 5,000 papers have been published studying the alleged beneficial properties of omega-3 fatty acids not to mention the billion dollar industry producing and selling fish oil capsules based on a hypothesis that was questionable from the beginning.'"

European iPhone Chargers Prone to Overheating

jones_supa jones_supa writes  |  about a month and a half ago

jones_supa (887896) writes "Apple has announced a "replacement program" for European iPhone AC/DC adapters sold between October 2009 and September 2012 after discovering they may overheat and thus pose a safety risk. The affected adapter, model A1300, was bundled with European sales of the iPhone 3GS, iPhone 4, and iPhone 4S, and was also sold separately. By a quick estimate, there must be millions of A1300s in the wild. The specific technical reason causing the overheating has not been detailed (a YouTube video shows a teardown of the device). The A1300 was replaced by an almost-identical adapter, A1400, in 2012, which is not affected by the safety issue. For more details on how to identify the affected adapter, and to arrange a replacement, visit Apple's dedicated portal for the issue."
