A reader points out that there is a great new panorama made from shots from the Curiosity Rover. "Sweep your gaze around Gale Crater on Mars, where NASA's Curiosity rover is currently exploring, with this 4-billion-pixel panorama stitched together from 295 images. ...The entire image stretches 90,000 by 45,000 pixels and uses pictures taken by the rover's two MastCams. The best way to enjoy it is to go into fullscreen mode and slowly soak up the scenery — from the distant high edges of the crater to the enormous and looming Mount Sharp, the rover's eventual destination."

A user writes "Concerned about their use as fronts for gambling operations, the Florida legislature passed a law banning Internet cafes. The law appears to be a reaction in part to the recent stepping down of Lt. Gov. Jennifer Carroll, embroiled in a scandal involving a company that operates Internet Cafes. More ordinary cafes with Wi-fi, where you supply your own computer (such as Starbucks), are not affected by the ban." The nomenclature here is confusing; the bill (PDF) (summary) is clearly aimed only at "cafes" that are essentially gambling venues; an Internet cafe wouldn't violate the proposed rule merely by providing computers. Whatever you think of prohibitions on gambling among consenting adults, the bill itself is sort of amusing for its very specific loopholes for bingo and "reverse vending machines."

sfcrazy writes "Quite a lot of people raised their eyebrows the way ex-Red Hat developer Matthew Garrett made Microsoft the 'universal' control of any desktops PCs running with UEFI secure boot. Though the intentions of Garrett were clear — to enable GNU/Linux to be able to run Linux on Windows 8 certified PCs with secure boot; it was clearly putting Microsoft in a very powerful position. Linus, while a supporter of secure boot, exploded at Garrett and Howells when they proposed its inclusion in the kernel. Linus responded: 'Guys, this is not a d*#@-sucking contest. If you want to parse PE binaries, go right ahead. If Red Hat wants to deep-throat Microsoft, that's *your* issue. That has nothing what-so-ever to do with the kernel I maintain. It's trivial for you guys to have a signing machine that parses the PE binary, verifies the signatures, and signs the resulting keys with your own key. You already wrote the code, for chissake, it's in that f*cking pull request.'" Update: 02/25 17:24 GMT by U L : The headline/article are misleading, since mjg seems to agree that the patch is a bit complicated : "(I mean, *I'm* fine with the idea that they're *@#$ing idiots and deserve to be miserable, but apparently there's people who think this is a vital part of a business model)". The issue at hand is a set of patches to load and store keys inside of a UEFI PE binary which is then passed to the kernel, which then extracts the keys from the binary. It's absurd, it's messy, and it's only needed because Microsoft will only sign PE binaries so not supporting it makes restricted boot even more difficult to support.

A user writes "The Landsat Data Continuity Mission is now in orbit, after launching Monday from Vandenberg Air Force Base in Calif. After about three months of testing, the U.S. Geological Survey will take control and the mission, renamed Landsat 8, will extend more than 40 years of global land observations critical to energy and water management, forest monitoring, human and environmental health, urban planning, disaster recovery, and agriculture." We still need more new observation satellites to avoid losing Earth observing capabilities as the work horses of the NASA/USGS fleet die of old age.

a user writes "Deloitte predicts that 8-character passwords will become insecure in 2013. Humans have trouble remembering passwords with more than seven characters, and it is difficult to enter long, complex passwords into mobile devices. Users have not adapted to increased computing power available to crackers, and continue to use bad practices such as using common and short passwords, and re-using passwords across multiple websites. A recent study showed that using the 10000 most common passwords would have cracked >98% of 6 million user accounts. All of these problems have the potential for a huge security hazard. Password vaults are likely to become more widely used out of necessity. Multifactor authentication strategies, such as phone texts, iris scans, and dongles are also likely to become more widespread, especially by banks."

A reader sends this quote from ZDNet: "Software that allows Windows apps to run on Android devices was demoed at the Fosdem 2013 open source conference this weekend. The demo by Alexandre Julliard, one of the original developers of Wine, showed Wine running on an emulated Android environment. Phoronix reports the performance of Wine on Android to be 'horrendously slow' but says these problems were attributed to it running on an emulated environment rather than a native Android OS. ... The makers claim it bypasses many performance and memory penalties of other methods for simulating computing environments, such as running virtual machines, by translating Windows API calls into POSIX calls on the fly. The Android OS predominantly runs on ARM-based devices today, and a separate demo at the Fosdem conference showed Wine running on ARM-based hardware. There was no news on when support for ARM-based devices or Android will be added to a publicly available Wine release."

A reader writes "Airline safety inspectors have found no faults with the battery used on Boeing's 787 Dreamliner, Japan's transport ministry has said. The battery was initially considered the likely source of problems on 787s owned by two Japanese airlines. The world's entire fleet of 50 787s has been grounded while inspections are carried out. Attention has now shifted to the electrical system that monitors battery voltage, charging and temperature. Transport ministry official Shigeru Takano said 'we have found no major quality or technical problem' with the lithium-ion batteries. Shares in GS Yuasa, which makes the batteries, jumped 5% on the news. 'We are looking into affiliated parts makers,' he said. 'We are looking into possibilities.'"

A reader sends news of researchers who encoded an MP3, a PDF, a JPG, and a TXT file into DNA, along with another file that explains the encoding. The researchers estimate the storage density of this technique at 2.2 petabytes per gram (abstract). "We knew we needed to make a code using only short strings of DNA, and to do it in such a way that creating a run of the same letter would be impossible. So we figured, let's break up the code into lots of overlapping fragments going in both directions, with indexing information showing where each fragment belongs in the overall code, and make a coding scheme that doesn't allow repeats. That way, you would have to have the same error on four different fragments for it to fail – and that would be very rare," said one of the study's authors. "We've created a code that's error tolerant using a molecular form we know will last in the right conditions for 10 000 years, or possibly longer," said another.

A reader notes that scientists at Cambridge University have found four-stranded DNA in human cells for the first time. "If you've ever studied genetics in school or college, you'll know that the structure of DNA is a double helix. You likely know that DNA carries all of our genetic code. While traditionally we think of only double helix DNA, scientists from Cambridge University in England have made an interesting discovery. According to the researchers, a quadruple helix is also present in some cells and is believed to relate to cancer in some ways. According to the researchers, controlling these quadruple helix structures could provide new ways to fight cancer. The scientists believe the quadruple helix may form when the cell has a certain genotype or operates in a certain dysfunctional state. Scientists have been able to produce quadruple helix material in test tubes for years. The material produced is called the G-quadruplex. The G refers to guanine, which is one of the base pairs that hold DNA together. The new research performed at the University is believed to be the first to firmly pinpoint quadruple helix in human cells."

A reader writes with this excerpt from CNET: "Installous, a major portal for pirated paid apps from Apple's App Store, won't be around anymore. Development team Hackulous today announced the closure of Installous on their official Web site. As of today, the pirated app store no longer works, and only shows these errors: 'Outdated version. Installous will now terminate' or 'API Error. API unavailable.' For many years, Installous offered complete access to thousands of paid iOS apps for free for anyone with a jailbroken iPhone, iPad, and iPod Touch. Think of it as being able to walk into a fancy department store, steal anything you want, and never get caught."

A reader writes "Nobel winner Dr. Rita Levi-Montalcini, who discovered chemical tools that the body uses to direct cell growth and build nerves, has died. She was 103. From the article: 'Dr. Rita Levi-Montalcini, a Nobel Prize-winning neurologist who discovered critical chemical tools that the body uses to direct cell growth and build nerve networks, opening the way for the study of how those processes can go wrong in diseases like dementia and cancer, died on Sunday at her home in Rome. She was 103. Her death was announced by Mayor Gianni Alemanno of Rome. "I don't use these words easily, but her work revolutionized the study of neural development, from how we think about it to how we intervene," said Dr. Gerald D. Fishbach, a neuroscientist and professor emeritus at Columbia. Scientists had virtually no idea how embryo cells built a latticework of intricate connections to other cells when Dr. Levi-Montalcini began studying chicken embryos in the bedroom of her house in Turin, Italy, during World War II. After years of obsessive study, much of it at Washington University in St. Louis with Dr. Viktor Hamburger, she found a protein that, when released by cells, attracted nerve growth from nearby developing cells.'"

A reader writes with an excerpt as carried by CNET of former Apple design chief Hartmut Esslinger's upcoming book, titled Design Forward: Creative Strategies for Sustainable Change. Writing of Steve Job's integration of design as an essential element across the company as a whole, Esslinger says: "The company's [then] CEO, Michael Scott, had created different business divisions for each product line, including accessories such as monitors and memory drives. Each division had its own head of design and developed its products the way it wanted to. As a result, Apple's products shared little in the way of a common design language or overall synthesis In essence, bad design was both the symptom and a contributing cause of Apple's corporate disease. Steve's desire to end the disjoined approach gave birth to a strategic design project that would revolutionize Apple's brand and product lines, change the trajectory of the company's future, and eventually redefine the way the world thinks about and uses consumer electronics and communication technologies." CNET shows off a few of those old designs (many of them appearing unsurprisingly fresh), but for much more of them see these images at designboom.

A reader writes "Salvador Rodriguez and Deborah Netburn of The Los Angeles Times have a rundown of the top 10 tech gaffes of 2012. From their article: 'As 2012 comes to a close we take a look back at the biggest "oops" moments of the last year. Whether it was an advertising misstep (Facebook's "Chair" commercial), or a product released before it was ready (Apple Maps), or just an idea that was ill-received (homeless men as Wi-Fi hotspots), we tried to compose a list of the times when the major players lost control of the narrative. It's also a reminder that everyone makes mistakes--even exacting tech companies.'"
