Lenovo UEFI Bug Only Likes Windows and RHEL 162

New submitter Nagilum23 writes "It looks like Lenovo only knows of Windows and RHEL where their Thinkcentre M92p desktop is concerned. While investigating UEFI boot issues, Matthew Garrett found the PC's firmware actually checks the descriptive string for the operating system, and will prevent unlisted operating systems from booting. Garrett writes, 'Every UEFI boot entry has a descriptive string. This is used by the firmware when it's presenting a menu to users - instead of "Hard drive 0" and "USB drive 3", the firmware can list "Windows Boot Manager" and "Fedora Linux". There's no reason at all for the firmware to be parsing these strings. ... there is a function that compares the descriptive string against "Windows Boot Manager" and appears to return an error if it doesn't match. What's stranger is that it also checks for "Red Hat Enterprise Linux" and lets that one work as well. ... This is, obviously, bizarre. A vendor appears to have actually written additional code to check whether an OS claims to be Windows before it'll let it boot. Someone then presumably tested booting RHEL on it and discovered that it didn't work. Rather than take out that check, they then addded another check to let RHEL boot as well." Note that this isn't a SecureBoot issue. Lenovo is aware of the problem and looking into it.

Ask Slashdot: How To Catch Photoshop Plagiarism? 284

First time accepted submitter jemenake writes "A friend of mine teaches electronic media (Photoshop, Premiere, etc.) at a local high-school. Right now, they're doing Photoshop, and each chapter in the book starts with an 'end result' file which shows what they're going to construct in that chapter, and then, given the basic graphical assets (background textures, photos, etc.), the students need to duplicate the same look in the final-result file. The problem, of course, is that some students just grab the final-result file and rename it and turn it in. Some are a little less brazen and they rename a few layers, maybe alter the colors on a few images, etc. So, it becomes time-consuming for her to open each file alongside the final-result file to see if it's 'too perfect.'" How to look for images closer than they should be to the original? Read on for more details.

Climate Change Could Drive Coffee To Extinction By 2080 345

Hugh Pickens writes "Coffee is the world's favorite beverage and the second-most traded commodity after oil. Now Nick Collins reports that rising global temperatures and subtle changes in seasonal conditions could make 99.7 per cent of Arabica-growing areas unsuitable for the plant before the end of the century and in some areas as soon as 2020. Even if the beans do not disappear completely from the wild, climate change is highly likely to impact yields. The taste of coffee, a beverage of choice among Slashdot readers, will change in future decades. 'The worst case scenario, as drawn from our analyses, is that wild Arabica could be extinct by 2080,' says Justin Moat. 'This should alert decision makers to the fragility of the species.'"

Linux Foundation Offers Solution for UEFI Secure Boot 308

Ever since news broke last year that Microsoft would require Windows 8 machines to have UEFI secure boot enabled, there were concerns that it would be used to block the installation of other operating systems, such as Linux distributions. Now, reader dgharmon sends this quote from Ars Technica about a new defense against that outcome: "The Linux Foundation has announced plans to provide a general purpose solution suitable for use by Linux and other non-Microsoft operating systems. The group has produced a minimal bootloader that won't boot any operating system directly. Instead, it will transfer control to any other bootloader — signed or unsigned — so that can boot an operating system." The announcement adds, "The pre-bootloader will employ a 'present user'; test to ensure that it cannot be used as a vector for any type of UEFI malware to target secure systems. This pre-bootloader can be used either to boot a CD/DVD installer or LiveCD distribution or even boot an installed operating system in secure mode for any distribution that chooses to use it."

Apple Adds Samsung Galaxy SIII To Its Ban List 553

After its big win against Samsung, Apple named 8 Samsung products it wanted an injunction to ban from sale in the U.S. Apple wasn't content with that, though; USA Today reports on the state of the expanded list: "The new list of 21 products includes Samsung's flagship smartphone Galaxy S III as well as the Galaxy Note, another popular Android phone. If the court finds those devices are infringing Apple's patents and irreparably harming the U.S. company, it could temporarily halt sales in the U.S. market even before the trial begins."

Apple Plans Hearing Aid Social Networking 70

theodp writes "Apple may have killed off Ping, its attempt at a music social network, but the USPTO on Thursday disclosed that Apple has patent-pending plans for a hearing aid-based social network. So, if Apple's granted patents covering its Social Network for Sharing a Hearing Aid Setting and method of Remotely Updating a Hearing Aid Profile, will it use them to 'go thermonuclear' on Google when the search giant gets around to improving its current offerings for the hard of hearing?"

Microsoft Apologizes For Inserting Naughty Phrase Into Linux Kernel 897

netbuzz writes "Microsoft has apologized and promised to rectify the fact that one of its developers slipped a sexist phrase into Linux kernel code supporting Microsoft's HyperV virtualization environment. In that code, the magic constant passed through to the hypervisor reads '0xB16B00B5,' or a slightly camouflaged 'BIG BOOBS.' After Linux developer/blogger Matthew Garrett criticized Microsoft for the stunt, the predictable debate over sexism in the technology world ensued. Microsoft issued a statement to Network World apologizing and added, 'We have submitted a patch to fix this issue and the change will be published in a future release of the kernel.'"

Richard Stallman Speaks About UEFI 549

An anonymous reader writes "Despite weaknesses in the Linux-hostile 'secure boot' mechanism, both Fedora and Ubuntu decided to facilitate it, by essentially adopting two different approaches. Richard Stallman has finally spoken out on this subject. He notes that 'if the user doesn't control the keys, then it's a kind of shackle, and that would be true no matter what system it is.' He says, 'Microsoft demands that ARM computers sold for Windows 8 be set up so that the user cannot change the keys; in other words, turn it into restricted boot.' Stallman adds that 'this is not a security feature. This is abuse of the users. I think it ought to be illegal.'"

Nobel Laureate Wiped From Pakistan's Textbooks As Heretic 445

Hugh Pickens writes writes "Alexander Abad-Santos writes that in any other country, the late Dr. Abdus Salam would be a national hero: he's the Nobel laureate in physics who laid the groundwork for the biggest physics discovery in the past 30 years--the Higgs boson. But that isn't the case in Pakistan, where Salam has been wiped from textbooks and history for not being fundamentalist enough. 'He belonged to the Ahmadi sect, which has been persecuted by the government and targeted by Taliban militants who view its members as heretics,' says Sebastian Abbot. 'His grand unification theory of strong, weak and electromagnetic fields opened the gateway for the discovery of bosons and laid down the basis for this quantum electrodynamics project,' writes Anam Khalid Alvi for Pakistan's Express Tribune. But Pakistan can't celebrate his achievements, since Ahmadis like Salam are and were prevented from 'posing as Muslims,' and can be punished with prison and even death. By contrast, fellow Pakistani physicist A.Q. Khan, who played a key role in developing the country's nuclear bomb and later confessed to spreading nuclear technology to Iran, North Korea and Libya, is considered a national hero. Khan is a Muslim."

Nicholas Carr Foresees Brains Optimized For Browsing 110

An anonymous reader writes "In the next decade, our brains are going to become optimized for information browsing, says best-selling author Nicholas Carr. According to Carr, while the genetic nature of our brains isn't being changed by the Internet at all, our brains are adapting 'at a cellular level' and are weakening modes of thinking we no longer exercise. Therefore, in 10 years, if human beings are using the Internet even more than they do today, says Carr, "our brains will be even more optimized for information browsing, skimming and scanning, and multitasking — fast, scattered modes of thought — and even less capable of the kinds of more attentive, contemplative thinking that the net discourages."" While Carr isn't making a case for Lamarckian evolution, the argument here seems weak to me; the same kind of brain change could be attributed to books, or television, or the automobile, couldn't it?

Scientists Work Towards Naturally Caffeine-Free Coffee 312

First time accepted submitter eternaldoctorwho writes "Research has been underway to produce a coffee bean plant that naturally has no or little caffeine content. Now, it looks like that might become a reality in the near future: Paulo Mazzafera of the University of Campinas in Brazil has come closer than ever with a strain containing 'only 2% of normal caffeine levels.' Coffee, anyone?"

Muslim Medical Students Boycott Darwin Lectures 1319

First time submitter Readycharged writes "The Daily Mail reports on a piece from The Sunday Times revealing that University College London have seen an increasing number of Muslim students boycotting lectures on Evolution due to clashes with the Koran. Steve Jones, Emeritus Professor of Human Genetics, says, 'I've had one or two slightly frisky discussions with kids who belonged to fundamentalist Christian churches, now it's Islamic overwhelmingly.' He adds, 'What they object to — and I don't really understand it, I am not religious — they object to the idea that there is a random process out there which is not directed by God.' The article also reveals that Evolutionary Biologist and former Oxford Professor Richard Dawkins also experienced Muslims walking out of such lectures."

I completed my enrollment the other day and am extremely psyched to have the opportunity to participate. Opted for the 'Basic' track as I don't have the time/energy for the whole enchilada. If they want to use my feedback to help develop a monetized version, that's fine with me; I get to learn cool stuff from smart people, and the provider of the service gets to improve their product.

Is This the Golden Age of Hacking? 213

Barence writes "With a seemingly continuous wave of attacks hitting the public and commercial sectors, there has never been a more prodigious period for hackers, argues PC Pro. What has led to the sudden hacking boom? Ease of access to tools has also led to an explosion in the numbers of people actively looking for companies with weakened defenses, according to security experts. Meanwhile, the recession has left thousands of highly skilled IT staff out of work and desperate for money, while simultaneously crimping companies' IT security budgets. The pressure to get systems up and running as quickly as possible also means that networks aren't locked down as tightly as they should be, which can leave back doors open for hackers."
