Dropbox Open Sources New Lossless Middle-Out Image Compression Algorithm (dropbox.com) 135

Dropbox announced on Thursday that it is releasing its image compression algorithm dubbed Lepton under an Apache open-source license on GitHub. Lepton, the company writes, can both compress and decompress files, and for the latter, it can work while streaming. Lepton offers a 22% savings reductions for existing JPEG images, and preserves the original file bit-for-bit perfectly. It compresses JPEG files at a rate of 5MB/s and decodes them back to the original bit at 15MB/s. The company says it has used Lepton to encode 16 billion images saved to Dropbox, and continues to utilize the technology to recode its older images. You can find more technical details here.

I think you should marry an overweight black single mother in her 40s with a charming personality to set a good example and show the world just how just and not racist you are.

For me, I stay in shape because that is a habit I have been able to forge due to my perseverance and quality of character. When I choose a woman to be with, I will choose a woman who represents similar values, one of which is not being a lazy entitled fat slob who thinks they are entitled to a partner who is not fat, lazy or entitled.

Sure, tolerance for the flaws of others is important in a relationship, but if you're unable to maintain a functional relationship with anyone, then it's probably because you had more tolerance for your own flaws than the flaws of your potential dating partners.

I'll bet that nobody would kick up much of a fuss if they decided to ban a photo of an anorexic model. Tess Holiday, being morbidly obese, obviously suffers from disordered eating due to a food addiction, yet is paraded around as some kind of paragon of moral virtue, while pictures of women with anorexia would be censored for being harmful to little girls. But seriously, do you think that presenting a morbidly obese woman as a socially acceptable norm sends girls a message about body image that is any less harmful?

So the article does have some valid points that differences in digestion efficiency, individual calorie expenditure or inaccuracies in listed nutrients, etc. could be sources of inaccuracy when planning your diet. However, what the average overweight person will take away from this is: Counting calories is useless, I might as well just give up.

Having been raised by a very obese mother, I know this attitude all too well. I too, was overweight and desired to keep my weight down and also believed that calorie restriction would mess up your metabolism and eventually make you even fatter.

Eventually, I challenged myself to stop eating sugar since I have a family history of diabetes, and luckily found that I was able to break through my previous sticking point. This inspired me to try to add a little more rigor into my routine, which eventually paid off big time. Now I'm lean and muscular and go to the gym regularly. I find that calorie counting with a food scale is VERY effective.

So I tend to find the fatalistic attitude people have regarding weight loss to be very destructive, not only to themselves and others.

Congress Gives Federal Agencies Two Weeks To Tally Backdoored Juniper Kit (csoonline.com) 77

itwbennett writes: In an effort to gauge the impact of the recent Juniper ScreenOS backdoors on government organizations, the House of Representatives is questioning around two dozen U.S. government departments and federal agencies. The U.S. House of Representatives' Committee on Oversight and Government Reform sent letters to the agencies on Jan. 21, asking them to identify whether they used devices running the affected ScreenOS versions, to explain how they learned about the issues and whether they took any corrective actions before Juniper released patches and to specify when they applied the company's patches. The questioned organizations have until Feb. 4 to respond and deliver the appropriate documents, a very tight time frame giving that 'the time period covered by this request is from January 1, 2009 to the present.'

University of Helsinki To Lay Off a Thousand People (yle.fi) 308

jones_supa writes: University of Helsinki, the place where Linus Torvalds got his degree as well, will reduce staff by 980 people, with 570 being laid off by the end of 2017. In addition, the university will reorganize and incorporate certain divisions including continuing education. Professors, teachers and researchers are criticizing the cuts, which coincide with the university's administrative and educational overhaul. The staff cuts reflect the government's drastic funding cuts to education, which plays one part in the effort of trying to help the difficult economic situation of today's Finland. The university estimates that of the 980 positions, terminations during this coming spring will account for 570 positions. Of the employees to be made redundant, 75 are teaching and research staff and 495 other staff. The rest of the cuts will be spread over the coming years.

Computer Beats Go Champion 149

Koreantoast writes: Go (weiqi), the ancient Chinese board game, has long been held up as one of the more difficult, unconquered challenges facing AI scientists... until now. Google DeepMind researchers, led by David Silver and Demis Hassabis, developed a new algorithm called AlphaGo, enabling the computer to soundly defeat European Go champion Fan Hui in back-to-back games, five to zero. Played on a 19x19 board, Go players have more than 300 possible moves per turn to consider, creating a huge number of potential scenarios and a tremendous computational challenge. All is not lost for humanity yet: DeepMind is scheduled to face off in March with Lee Sedol, considered one of the best Go players in recent history, in a match compared to the Kasparov-Deep Blue duels of previous decades.

Creator of Minecraft Develops Experimental VR Project (roadtovr.com) 63

An anonymous reader writes: Despite his on-again off-again relationship with VR headset maker Oculus, the creator of Minecraft, Markus "Notch" Persson, has developed an experimental virtual reality project that leverages WebVR technology to run directly within a browser using a Rift DK2 headset. Notch contributed $10,000 to Oculus' 2012 Kickstarter, and even traveled from Europe to visit the company in its early days. After Facebook's $2 billion acquisition of Oculus in 2014, his enthusiasm dwindled, saying "I definitely want to be a part of VR, but I will not work with Facebook." One month before selling his own company to Microsoft for a similar sum, he said he was "officially over being upset about Facebook buying Oculus."

DeLoreans To Go Back To Production (cnn.com) 276

An anonymous reader writes: The last time a DeLorean was built was about 35 years ago, but that is all about to change. Next year, you'll be able to buy a new 2017 DeLorean to satisfy all your deepest Back to the Future dreams. CNN reports: "The new production plan is itself something of a time warp. The cars will be built from an inventory of a million spare parts that have been in storage ever since the Belfast plant closed. Only the engine will be a creature of the 21st century."

The Tragedy Of Apollo 1 And The Lessons That Brought Us To The Moon (forbes.com) 118

An anonymous reader writes: On January 27, 1967, the Apollo 1 crew was performing a "plugs-out" test of the Command/Service Module, an essential simulation of how the three-person capsule would perform under in-space conditions under its own power. At 6:30 PM, a voltage spike occurred, leading to a disaster. In 26 seconds, everything changed. The Apollo 1 fire and the tragic death of all three astronauts wasn't due to just a single point-of-failure, but rather due to five independent confounding factors that if any one of them had been different, the astronauts Grissom, White and Chaffee might have survived. As it stands, all the crewed Apollo missions were scrapped for 20 months while NASA changed how they did business. The changes worked remarkably well, and 2.5 years later, humans walked on the Moon.

Android Ransomware Threatens To Share Your Browsing History With Your Friends (symantec.com) 160

An anonymous reader writes: The newly discovered Lockdroid ransomware is unique in two ways. First it uses perfectly overlaid popups to trick users into giving it admin privileges. This trick works on devices running Android versions prior to 5.0 (Lollipop), which means 67% of all Android smartphones. Secondly, after it encrypts files and asks for a ransom, it also steals the user's browsing history and contacts list, and blackmails the user to pay the ransom, or his browsing history will be forwarded to his contacts.
