Thank Van Allen’s Belts and Richter’s Rockets

first_imgInvisible shields above the Earth protect us all from dangerous radiation. New space probes explore how they do it.When Dr. James Van Allen of the University of Iowa wondered why his geiger counters aboard America’s first Explorer satellites became saturated at certain altitudes, he suspected he had found something important. Large lobed belts of high-energy radiation were named the Van Allen Belts in his honor. The instruments had been mounted in the craft by Dr. Henry Richter, last surviving manager of the Explorer program. He wrote about the discovery in his 2015 book America’s Leap Into Space: My Time at JPL and the First Explorer Satellites. Newly updated with an index, the book (nominated for a Eugene M. Emme Astronautical Literature Award) is an important first-hand account of that historic period in the newly-dawned space age.Two zones of radiation were identified early on. “This simple picture of the radiation belts persisted for decades until 2012, when a pair of probes was launched to study them in detail,” Space.com says. “This was the first time that two spacecraft simultaneously studied the radiation belts, trading information with each other to build a bigger picture.” The findings are exciting and vital to life on Earth:Data gathered by the probes also showed that the radiation belts shield Earth from high-energy particles. “The barrier for the ultrafast electrons is a remarkable feature of the belts,” study lead author Dan Baker, of the University of Colorado in Boulder, said in a statement.“We’re able to study it for the first time, because we never had such accurate measurements of these high-energy electrons before.”The Van Allen Probes have revealed the dynamic nature of our space shield. “Space tsunamis” from solar outbursts called coronal mass ejections cause rapid changes in the belt structure, accelerating electrons to near light speed. Engineers watched one particular reaction when the two probes were monitoring different positions.“The spacecraft measured a sudden pulse of electrons energized to extreme speeds — nearly as fast as the speed of light — as the shock slammed the outer radiation belt,” NASA wrote at the time. “This population of electrons was short-lived, and their energy dissipated within minutes. But five days later, long after other processes from the storm had died down, the Van Allen probes detected an increased number of even higher energy electrons. Such an increase so much later is a testament to the unique energization processes following the storm.“Lessons learned from these reactions help engineers design better radiation protection for astronauts, the article says.Dr. Henry Richter is an American VIP who is still active at age 88 with his wife (age 90) in southern California. He was instrumental in the design of the Explorer, Ranger and Surveyor spacecraft at JPL, and development of the Deep Space Network. He is also a Christian and a young-earth creationist. The CEH editor is working with him on a new book that will share wonders of creation and end with his story of how he came to Christ. The draft is currently being reviewed by the publisher and may be available late this year or in 2017; watch for announcements in these pages.Note: CEH is taking a break till Oct. 1.

Google TV Jailbreak Opens the Doors to Developers, Hulu

first_imgTags:#Internet TV#New Media#news#web Why Tech Companies Need Simpler Terms of Servic… A Web Developer’s New Best Friend is the AI Wai… Related Posts 8 Best WordPress Hosting Solutions on the Marketcenter_img Top Reasons to Go With Managed WordPress Hosting mike melanson At the end of November, Android developer Howard Harte announced that he would give $1,000 to the first person who could jailbreak the Google TV. Just over a month later, the $1,000 has been collected and Harte says he is now “having a lot of fun” coding on his hacked unit…and likely watching some free Hulu. A group of developers called the GTVHacker dev team cracked the code on January 5, opening up the Google TV platform to brave, screwdriver-wielding developers everywhere. (Video proof inside.)“What this means is that we now have a complete Android development environment for the Google TV,” explained Harte in an email. “I am able to use standard Android development tools to develop for GTV, just like developing for any other Android device.”Don’t expect this hack to be widely adopted by Hulu-loving GTV fans everywhere, however. Jailbreaking the Logitech Revue unit involves opening up the box, soldiering some wires onto the circuit board, and then going through a relatively lengthy software hack.“The most important thing for developers though is that they now have full access to developing for the platform well in advance of Google releasing the tools,” wrote Harte. “Now, it should be possible for Rovio to port Angry Birds […] to the Google TV.”The GTVHacker dev team recorded a video of its jailbroken Logitech Revue unit, showing off “bypassed content block and custom application install.” Take a look at Hulu on Google TV and more:Update: Harte contacted us with a few minor corrections, writing “the actual bounty paid was $500, since the rooting process involved a hardware hack. The $1000 bounty was for a software-only hack, which unfortunately did not happen. The original terms of the bounty stated that ‘a partial consideration of $500 will be given for a hardware hack’ and that a hardware hack is defined as any hack which involves opening the Google TV device.One other minor correction, I don’t use it to watch Hulu, I only use it to develop apps…”What, if not free Hulu, does a jailbroken Google TV mean, then? First off, it’s likely that someone will come up with a software-only jailbreak at some point in the future. Beyond that, however, giving root access to daring developers means that, when Google finally opens its Google TV marketplace, developers will have had a head start figuring out the ins and outs of the system. We’re curious to see where Google TV could go with the innovation of the developer community.For those of you interested in all the geeky details, here’s Harte’s explanation:The GTVHacker dev team consists of five members, and was started by Zenofex, who was able to connect a terminal to the Revue’s UART1 serial port. This involved opening the Revue and soldering three wires, so it qualifies as a hardware hack. After connecting the serial terminal to UART1, Zenofex found a root shell running in Recovery Mode. With that, he had root access, but no way to install apps.Zenofex enlisted the help of four other software hackers to assmble a toolchain for compiling the necessary tools to add “ADB” support to the Revue. Adding ADB, which is the Android Debug Bridge, allowed installing apps with standard adb commands over the network interface (either Ethernet or WLAN.)With that complete, Apps that were written in Java would run fine on the Revue, and they had “Astro File Manager” running in short order. At this point, Zenofex contacted me to get a copy of my “Better Terminal Emulator Pro” app, which was required to be shown running on the Revue in a YouTube video under the terms of the “Root Bounty” offering.It turned out that Better Terminal Emulator Pro, which relies heavily on Native (CPU-specific) code did not run on the Revue. What was needed was Google’s Android Native Development Kit (NDK) for Google TV. Since that was not officially available, one clever GTVHacker member was able to combine the NDK from the Android-x86.org project with Intel’s toolchain to produce a working NDK for the GTV. With this done, they recompiled the native shared library used by Better Terminal Emulator Pro for the GTV, and BTEP installed fine on the Revue and works.last_img read more

Canonical Adds OpenStack Support to Ubuntu

Natty Narwhal will include OpenStack, the open source cloud computing platform created by NASA and Rackspace last year. Canonical joined OpenStack in February.OpenStack will compliment Eucalyptus, the open core cloud computing system. “We want people to think of Ubunutu as a Linux platform that is cloud native,” Canonical VP of Business Development told InternetNews.com.NASA started what eventually became OpenStack to in order to replace Eucalypsis, The Register reported last year. Since that time, Eucalyptus has partnered with Red Hat and has been working to make its platform more open.George also told InternetNews.com that while Ubuntu will support two cloud standards for now, it will eventually “bless” only one – much like it has “blessed” the KVM hypervisor instead of Xen.Although OpenStack has met with much enthusiasm from the open source community, some crack are starting to show in its governance model as we’ve reported. Still, it’s a young project with strong technology and serious backing.But Eucalyptus is a formidable opponent in the cloud stack standard race, especially with its Red Hat partnership.OpenStack is only a technology preview at the moment. But this week’s Amazon Web Services outage emphasizes the need for open cloud standards so that servers can be moved easily from cloud to cloud. The clock is ticking.

How to Create a Vintage Look in a Digital World

first_imgLearn how to create an authentic period look from the cinematographers behind Fargo and Stranger Things.  Cover image via Keslow Camera.Dana Gonzales, ASC recently spoke about the light sources he used filming Season Two of Fargo. For a series set in the ’60s, he researched and found that the sodium vapor street lamps were not period accurate. He and his lighting team then fit all the street lamps — and other practical sources — with warm tungsten bulbs to match the color of light that would have been appropriate for the period.In search of period-perfect nighttime ambience, Gonzales and his team replaced every sodium-lamp streetlight in the Canadian town standing in for Luverne, Minn., where hapless butcher Ed and his beautician wife, Peggy, have their shops.We changed the bulbs of that whole street back to warm tungsten lights. I went to great lengths creating a mood with this kind of lighting because it pulls the audience into the world when the story takes place. People come up to me all the time and say, ‘Fargo reminds me of this street I used to live on in the ’70s without knowing why.’ Well, a lot of that feeling has to do with the color of the light.LensesVintage lenses are hot right now. Everything from Kowa Anamorphics and Canon K-35s are helping to provide this vintage look in the digital age. Each lens has unique characteristics. Even modern lenses can offer some vintage characteristics. For this reason, it’s always wise to test a variety of lenses if you’re going after a certain look. This is exactly what Stranger Things cinematographer Tim Ives did when creating the look of the show.I found the Leica had a flatness and smoothness and roundness to them, which made the skin tone just beautiful and had that ’80s feel to them. We wanted the contrast and did not want it to feel flat and overlit. I wanted it to be dark. This is a horror fantasy show and wanted the details to be in the shadows.FiltrationFiltration can play a huge role in achieving a vintage or period look. One of my personal favorites is Black ProMist diffusion for achieving a vintage vibe. It introduces a beautiful halation to the images and gives the shadows a pleasant creaminess while still maintaining contrast. It’s also a great way to soften up sharp digital images but maintain the sharpness in the eyes to create a perfect balance. Take a look at the video below to catch a glimpse at what the different strengths of Black ProMist can offer.Art DepartmentFilmmaking is a team sport. One of the most important things to consider when achieving a period look is to work closely with the art department to achieve the desired outcome. No matter what camera and lens combination you use as a cinematographer, if the art isn’t period accurate, it will never sell the setting to an audience. Here’s what Tim Ives had to say about working with the art department of the show:Chris Trujillo’s sets were just amazing. The love and care he put into them is what you see on the screen … Then you look at other departments, like hair and make-up and wardrobe. The hair was exactly how it would be in the ’80s. Everything we put in front of the camera really had the essence of those ’80s things we really love.There are a lot of components that go into selling a period film. However, these four avenues will offer a great start on the path to achieving your desired look.What techniques do you use to achieve a period look? Let us know in the comments.last_img read more
