GPS III Launching Today But You Can’t Use It Until 2022

December 18, 2018 by Al Williams 49 Comments

Imagine if you bought a new car but they keys were not going to be shipped to you until a few years later. That’s analogous to the situation the U.S. Air Force finds itself in. The first GPS III satellite is finally ready to launch today, December 18, 2018 — a little over 2 years beyond the original schedule. However, most of the unique GPS III features won’t be available until at least 2022, according to a 2017 Government Accounting Office (GAO) report to Congress.

GPS III is a project to launch 32 new satellites that will — for military users — be more difficult to jam. For civilian users, the new GPS satellites will be compatible with other systems, including the EU’s Galileo system. But the big draw? About three times the accuracy of the current system. For civilian use, that means 3 to 10 feet under good conditions as opposed to the current systems’ 10- to 33-foot resolution.

Welcome To The Slow Death Of Satellite TV In America

December 17, 2018 by Tom Nardi 131 Comments

During an earnings call on November 29th, CEO of AT&T Communications John Donovan effectively signed the death warrant for satellite television in the United States. Just three years after spending $67 billion purchasing the nations’s largest satellite TV provider, DirecTV, he made a comment which left little doubt about the telecom giant’s plan for the service’s roughly 20 million subscribers: “We’ve launched our last satellite.”

The news might come as a surprise if you’re a DirecTV customer, but the writing has been on the wall for years. When the deal that brought DirectTV into the AT&T family was inked, they didn’t hide the fact that the actual satellite content delivery infrastructure was the least of their concerns. What they really wanted was the installed userbase of millions of subscribers, as well as the lucrative content deals that DirecTV had already made. The plan was always to ween DirecTV customers off of their satellite dishes, the only question was how long it would take and ultimately what technology they would end up using.

Now that John Donovan has made it clear their fleet of satellites won’t be getting refreshed going forward, the clock has officially started ticking. It won’t happen this year, or even the year after that. But eventually each one of the satellites currently beaming DirecTV’s content down to Earth will cease to function, and with each silent bird, satellite television (at least in the United States) will inch closer to becoming history.

MakerBot Moves Away From Makers With New Printer

December 11, 2018 by Tom Nardi 53 Comments

If you’ve been following the desktop 3D printing market for the last couple years, you’re probably aware of the major players right now. Chinese companies like Creality are dominating the entry level market with machines that are priced low enough to border on impulse buys, Prusa Research is iterating on their i3 design and bringing many exciting new features to the mid-range price point, and Ultimaker remains a solid choice for a high-end workhorse if you’ve got the cash. But one name that is conspicuously absent from a “Who’s Who” of 3D printing manufacturers is MakerBot; despite effectively creating the desktop 3D printing market, today they’ve largely slipped into obscurity.

So when a banner popped up on Thingiverse (MakerBot’s 3D print repository) advertising the imminent announcement of a new printer, there was a general feeling of surprise in the community. It had been assumed for some time that MakerBot was being maintained as a zombie company after being bought by industrial 3D printer manufacturer Stratasys in 2013; essentially using the name as a cheap way to maintain a foothold in the consumer 3D printer market. The idea that they would actually release a new consumer 3D printer in a market that’s already saturated with well-known, agile companies seemed difficult to believe.

But now that MakerBot has officially taken the wraps off a printer model they call Method, it all makes sense. Put simply, this isn’t a printer for us. With Method, MakerBot has officially stepped away from the maker community from which it got its name. While it could be argued that their later model Replicator printers were already edging out of the consumer market based on price alone, the Method makes the transition clear not only from its eye watering $6,500 USD price tag, but with its feature set and design.

That said, it’s still an interesting piece of equipment worth taking a closer look at. It borrows concepts from a number of other companies and printers while introducing a few legitimately compelling features of its own. While the Method might not be on any Hackaday reader’s holiday wish list, we can’t help but be intrigued about the machine’s future.

The Space Station Has A Supercomputer Stowaway

December 10, 2018 by Tom Nardi 59 Comments

The failed launch of Soyuz MS-10 on October 11th, 2018 was a notable event for a number of reasons: it was the first serious incident on a manned Soyuz rocket in 35 years, it was the first time that particular high-altitude abort had ever been attempted, and most importantly it ended with the rescue of both crew members. To say it was a historic event is something of an understatement. As a counterpoint to the Challenger disaster it will be looked back on for decades as proof that robust launch abort systems and rigorous training for all contingencies can save lives.

But even though the loss of MS-10 went as well as possibly could be expected, there’s still far reaching consequences for a missed flight to the International Space Station. The coming and going of visiting vehicles to the Station is a carefully orchestrated ballet, designed to fully utilize the up and down mass that each flight offers. Not only did the failure of MS-10 deprive the Station of two crew members and the experiments and supplies they were bringing with them, but also of a return trip which was to have brought various materials and hardware back to Earth.

But there’s been at least one positive side effect of the return cargo schedule being pushed back. The “Spaceborne Computer”, developed by Hewlett Packard Enterprise (HPE) and NASA to test high-performance computing hardware in space, is getting an unexpected extension to its time on the Station. Launched in 2017, the diminutive 32 core supercomputer was only meant to perform self-tests and be brought back down for a full examination. But now that its ticket back home has been delayed for the foreseeable future, NASA is opening up the machine for other researchers to utilize, proving there’s no such thing as a free ride on the International Space Station.

Weaponized Networked Printing Is Now A Thing

December 7, 2018 by Tom Nardi 37 Comments

It’s a fairly safe bet that a Venn diagram of Hackaday readers and those who closely follow the careers of YouTube megastars doesn’t have a whole lot of overlap, so you’re perhaps blissfully unaware of the man who calls himself [PewDiePie]. As such, you might not know that a battle between himself and another YouTube channel which uploads Bollywood music videos has reached such a fever pitch that his fans have resorted to guerrilla hacking to try to sway public opinion towards their side. It’s perhaps not the dystopian future we imagined, but it just might be the one we deserve.

To briefly summarize the situation, a hacker known only by the handle [TheHackerGiraffe] decided to help out Dear Leader by launching an automated attack against 50,000 Internet connected printers. When the hack was successful, the printer would spit out a page of digital propaganda, complete with fist ASCII art, that urged the recipient to go on YouTube and pledge their support for [PewDiePie]. There’s some debate about how many of the printers [TheHackerGiraffe] targeted actually delivered their payload, but judging by reactions throughout social media, it was enough to get the message out.

While the stunt itself may have come as a surprise, the methodology wasn’t. In fact, the only surprising element to the security researchers who’ve weighed in on the situation is that this hasn’t happened more often. It certainly isn’t the first time somebody’s done it, but the fact that this time its been connected to such a high profile Internet celebrity is putting more eyes on the problem then there have been in the past. Now that the proverbial cat is out of the bag, there are even websites springing up which claim to be purveyors of “Printer Advertising”. Odds are good this won’t be the last time somebody’s printer starts running off more than TPS reports.

We here at Hackaday don’t have much interest in the battle for YouTube supremacy. We’re just pulling for Dave Jones’s EEVBlog channel to join [AvE] in breaking a million subscribers. But we’re very interested in the technology which made this attack possible, how likely it is we’re going to see more people exploit it, and what are we supposed to do now that even our own printers can be turned against us?

Amazon Thinks ARM Is Bigger Than Your Phone

December 3, 2018 by Tom Nardi 56 Comments

As far as computer architectures go, ARM doesn’t have anything to be ashamed of. Since nearly every mobile device on the planet is powered by some member of the reduced instruction set computer (RISC) family, there’s an excellent chance these words are currently making their way to your eyes courtesy of an ARM chip. A userbase of several billion is certainly nothing to sneeze at, and that’s before we even take into account the myriad of other devices which ARM processors find their way into: from kid’s toys to smart TVs.

ARM is also the de facto architecture for the single-board computers which have dominated the hacking and making scene for the last several years. Raspberry Pi, BeagleBone, ODROID, Tinker Board, etc. If it’s a small computer that runs Linux or Android, it will almost certainly be powered by some ARM variant; another market all but completely dominated.

It would be a fair to say that small devices, from set top boxes down to smartwatches, are today the domain of ARM processors. But if we’re talking about what one might consider “traditional” computers, such as desktops, laptops, or servers, ARM is essentially a non-starter. There are a handful of ARM Chromebooks on the market, but effectively everything else is running on x86 processors built by Intel or AMD. You can’t walk into a store and purchase an ARM desktop, and beyond the hackers who are using Raspberry Pis to host their personal sites, ARM servers are an exceptional rarity.

Or at least, they were until very recently. At the re:Invent 2018 conference, Amazon announced the immediate availability of their own internally developed ARM servers for their Amazon Web Services (AWS) customers. For many developers this will be the first time they’ve written code for a non-x86 processor, and while some growing pains are to be expected, the lower cost of the ARM instances compared to the standard x86 options seems likely to drive adoption. Will this be the push ARM needs to finally break into the server and potentially even desktop markets? Let’s take a look at what ARM is up against.

Sci-Hub: Breaking Down The Paywalls

November 27, 2018 by Steven Dufresne 125 Comments

There’s a battle going on in academia between the scientific journal publishing companies that have long served as the main platform for peer review and spreading information, and scientists themselves who just want to share and have access to the work of their fellows. arxiv.org launched the first salvo, allowing researchers in physics to self-publish their own papers, and has gained some traction in mathematics and computer science. The Public Library of Science journals focus on biology and medicine and offer peer review services. There are many others, and even the big firms have been forced to recognize the importance of open science publication.

But for many, that’s still not enough. The high prestige journals, and most past works, are stuck behind paywalls. Since 2011, Sci-Hub has taken science publishing open by force, illegally obtaining papers and publishing them in violation of copyright, but at the same time facilitating scientific research and providing researchers in poorer countries with access that their rich-world colleagues take for granted. The big publishing firms naturally fought back in court and won, and with roughly $20 million of damages, drove Sci-Hub’s founder underground.
