Hackers And Heroes: Rise Of The CCC And Hackerspaces

January 12, 2016 by Elliot Williams 27 Comments

From its roots in phone phreaking to the crackdowns and legal precedents that drove hacking mostly underground (or into business), hacker culture in the United States has seen a lot over the last three decades. Perhaps the biggest standout is the L0pht, a visible 1990s US hackerspace that engaged in open disclosure and was, arguably, the last of the publicly influential US hacker groups.

The details of the American hacker scene were well covered in my article yesterday. It ended on a bit of a down note. The L0pht is long gone, and no other groups that I know of have matched their mix of social responsibility and public visibility. This is a shame because a lot of hacker-relevant issues are getting decided in the USA right now, and largely without our input.

Chaos Computer Club

But let’s turn away from the USA and catch up with Germany. In the early 1980s, in Germany as in America, there were many local computer clubs that were not much more than a monthly evening in a cafeteria or a science museum or (as was the case with the CCC) a newspaper office. Early computer enthusiasts traded know-how, and software, for free. At least in America, nothing was more formally arranged than was necessary to secure a meeting space: we all knew when to show up, so what more needed to be done?

Things are a little different in the German soul. Peer inside and you’ll find the “Vereinsmentalität” — a “club-mentality”. Most any hobby or sport that you can do in Germany has an associated club that you can join. Winter biathlon, bee-keeping, watercolor painting, or hacking: when Germans do fun stuff, they like to get organized and do fun stuff together.

LUX Searches In The Deep For Dark Matter

January 12, 2016 by Mike Szczys 38 Comments

The Homestake Mine started yielding gold in 1876. If you had asked George Hearst, the operator at the time, if the mine would someday yield the secrets of the universe I bet he would have laughed you out of the room. But sure enough, by 1960 a laboratory deep in the mine started doing just that. Many experiments have been conducted there in the five and a half decades since. The Large Underground Xenon (LUX) experiment is one of them, and has been running is what is now called the Sanford Underground Research Facility (SURF) for about four years. LUX’s first round of data was collected in 2013, with the experiment and the rest of the data slated to conclude in 2016. The method, hardware, and results wrapped up in LUX are utterly fascinating.

Hacking Online Reviews

January 11, 2016 by Al Williams 37 Comments

For this post, I want to return the word hacking to its nefarious definition. We prefer the kinder definition of a hacker as someone who creates or modifies things to fit some purpose or to improve its function. But a hacker can also be someone who breaks into computer systems or steals phone service or breaks encryption.

There are some “hacker battlefields” that are very visible. Protecting credit card numbers from hackers is a good example. But there are some subtle ones that many people don’t notice. For example, the battle for online reviews. You know, like on Amazon when you rate the soldering iron you bought and leave a note about how it works. That might seem like a strange place for hacking until you stop and think about why people do bad hacking.

Hackers And Heroes: A Tale Of Two Countries

January 11, 2016 by Elliot Williams 42 Comments

Hacker culture in Germany and the US is very similar in a lot of ways, from the relative mix of hardware versus software types to the side-affinities for amateur radio and blinkenlights. Reading Hackaday, you’ll find similar projects coming out of both countries. Both countries have seen hackerspaces bloom in the last decade to the point that there’s probably one or two in whatever city you’re living in. But there’s one thing that hackers in the USA are still lacking that German hackers have had for a while: respect.

Say the word “hacker” in different social circles, and you never know what kind of response you’re going to get. Who exactly are “hackers” anyway? Are we talking about the folks blackmailing you for your account details on Ashley Madison? Or stealing credit card numbers from Target? Or are we talking about the folks who have a good time breaking stuff and building stuff, and taking things apart to see how they work?

The discussion over who’s a “hacker” is as old as the hills, by Internet standards anyway, and it’s not going to get settled here. But think about the last time you heard the word “hacker” used in anything but its negative sense in the popular press. If you can’t remember a single instance in this century, you’re living in the USA. If you answered, “just yesterday, in one of the nation’s most important newspapers”, then you’re living in Germany.

Ode To The TL431, And A LiFePO4 Battery Charger

January 8, 2016 by Elliot Williams 85 Comments

Nerd Ralph loves cheap and dirty hacks, and for that we applaud him. His latest endeavor is a LiFePO4 battery charger that he made out of parts he had on hand for under $0.50 US. (Although we think he really made it for the fun of making it.)

The circuit is centered around a TL431 programmable shunt regulator, which is an awesome and underrated chip in its own right. If you don’t know the TL431 (aka LM431), you owe it to yourself to fetch the datasheet and pick up a couple with your next electronics part order. In fact, it’s such a great chip, we can’t resist telling you about it for a minute.

Surviving The FAA Regulations: Modelers Move Indoors

January 8, 2016 by Adam Fabio 46 Comments

New FAA rules are making radio-controlled aircraft a rough hobby to enjoy here in the USA. Not only are the new drone enthusiasts curtailed, but the classic radio-controlled modelers are being affected as well. Everyone has to register, and for those living within 30 miles of Washington DC, flying of any sort has been effectively shut down. All’s not lost though. There is plenty of flying which can be done outside of the watchful eye of the FAA. All it takes is looking indoors.

The Most Plausible Apollo Moon Landing Conspiracy Ever Devised

January 6, 2016 by Brian Benchoff 247 Comments

The Internet is polluted with craziness, and there is no better example than YouTube. If you’ve ever wondered what would happen when you give everyone on the planet the power to show everyone else on the planet their innermost thoughts, desires, and insane ramblings, you need only look at YouTube.

One of the biggest offenders of incoherent ramblings is the subject of spaceflight. Simply search ‘space shuttle’ on YouTube, and you’ll find accusations of the crew of Columbia being abducted by aliens. Crazy, incoherent, and somewhat insulting. Accusations of a moon landing conspiracy are unavoidable in the ‘related videos’ section and are similarly filled with videos from people with either a tenuous grasp of reality or too much time on their hands.

A broken clock is right twice a day, a broken calendar is right every twenty-eight years or so, and every once in a while, simply from the volume of videos on the subject, one conspiracy theorist will present a new and novel idea. Here we present perhaps the only moon landing conspiracy theory that makes sense, is consistent with physical laws, and that may actually be true.
