How Has Amazon Managed To Make Hackers Love Alexa?

December 19, 2016 by Jenny List 115 Comments

Our hackspace has acquired an Amazon Dot, courtesy of a member. It mostly seems to be used as a source of background music, but it has also spawned a seemingly never-ending new entertainment in which the hackspace denizens ceaselessly bait their new electronic companion with ever more complex and esoteric requests. From endless rephrasing and careful enunciation of obscure early reggae artists to try to settle a musical argument to hilarious mis-hearing on the part of our silicon friend, the fun never stops. “Alexa, **** off!” it seems results in “I’m sorry, I can’t find a device of that name on this network”.

That is just the experience of one hackspace, but it evidently does not end there. Every other day it seems that new projects using Alexa pass through the Hackaday timeline, so it looks as though Amazon’s online personal assistant has been something of a hit within our community.

Fair enough, you might say, we’re always early adopters of any new technology. But it’s a development over which I wonder; am I alone in finding it surprising? It’s worth taking a moment to look at the subject.

Self-Driving Cars Are Not (Yet) Safe

December 5, 2016 by Elliot Williams 123 Comments

Three things have happened in the last month that have made me think about the safety of self-driving cars a lot more. The US Department of Transportation (DOT) has issued its guidance on the safety of semi-autonomous and autonomous cars. At the same time, [Geohot]’s hacker self-driving car company bailed out of the business, citing regulatory hassles. And finally, Tesla’s Autopilot has killed its second passenger, this time in China.

At a time when [Elon Musk], [President Obama], and Google are all touting self-driving cars to be the solution to human error behind the wheel, it’s more than a little bold to be arguing the opposite case in public, but the numbers just don’t add up. Self-driving cars are probably not as safe as a good sober driver yet, but there just isn’t the required amount of data available to say this with much confidence. However, one certainly cannot say that they’re demonstrably safer.

Automate The Freight: Robotic Deliveries Are On The Way

November 23, 2016 by Dan Maloney 162 Comments

Seems like all the buzz about autonomous vehicles these days centers around self-driving cars. Hands-free transportation certainly has its appeal – being able to whistle up a ride with a smartphone app and converting commute time to Netflix binge time is an alluring idea. But is autonomous personal transportation really the killer app that everyone seems to think it is? Wouldn’t we get more bang for the buck by automating something a little more mundane and a lot more important? What about automating the shipping of freight?

Look around the next time you’re not being driven to work by a robot and you’re sure to notice a heck of a lot of trucks on the road. From small panel trucks making local deliveries to long-haul tractor trailers working cross-country routes, the roads are lousy with trucks. And behind the wheel of each truck is a human driver (or two, in the case of team-driven long-haul rigs). The drivers are the weak point in this system, and the big reason I think self-driving trucks will be commonplace long before we see massive market penetration of self-driving cars.

Apple Sucks Now, Here’s A ThinkPad Buyer’s Guide

October 28, 2016 by Brian Benchoff 247 Comments

For the last decade, Macs have been running a UNIX-ish operating system on x86 processors. They’ve been fantastic developer’s machines, and the MacBook Pro is the de facto standard laptop issued to all developers, all hackathon attendees, and arguably, anyone who does real work with a computer.

This week, Apple unveiled the latest MacBook Pro and provided more evidence Steve Jobs actually knew what he was doing. Fifteen hundred bones will get you a MacBook Pro with a last-gen processor, an Escape key, a headphone jack, and two Thunderbolt 3 ports (with one port required for charging). The next model up costs $1800, ditches the Escape key for a dedicated emoji bar, and includes four Thunderbolt 3 ports.

In the past, I have defended people who choose MacBooks as their laptop of choice. A MacBook is a business-class laptop, and of course carries a higher price tag. However, Apple’s latest hardware release was underwhelming and overpriced. If you’re looking for a new laptop, you would do well to consider other brands. To that end, here’s a buyer’s guide to ThinkPads, currently the second most popular laptop I’ve seen with the dev/hacker/code cracker crowd.

Death To The 3.5mm Audio Jack, Long Live Wireless

October 25, 2016 by Gerrit Coetzee 361 Comments

There’s been a lot of fuss over Apple’s move to ditch the traditional audio jack. As for me, I hope I never have to plug in another headphone cable. This may come off as gleeful dancing on the gravesite of my enemy before the hole has even been dug; it kind of is. The jack has always been a pain point in my devices. Maybe I’ve just been unlucky. Money was tight growing up. I would save up for a nice set of headphones or an mp3 player only to have the jack go out. It was a clear betrayal and ever since I’ve regarded them with suspicion. Is this the best we could do?

I can’t think of a single good reason not to immediately start dumping the headphone jack. Sure it’s one of the few global standards. Sure it’s simple, but I’m willing to take bets that very few people will miss the era of the 3.5mm audio jack once it’s over. It’s a global episode of the sunk cost fallacy.

In the usual way hindsight is 20/20, the 3.5mm audio jack can be looked at as a workaround, a stop over until we didn’t need it. It appears to be an historic kludge of hack upon hack until something better comes along. When was the last time it was common to hook an Ethernet cable into a laptop? Who would do this when we can get all the bandwidth we want reliably over a wireless connection. Plus, it’s not like most Ethernet cables even meet a spec well enough to meet the speeds they promise. How could anyone reasonably expect the infinitely more subjective and variable headphone and amplifier set to do better?

But rather than just idly trash it, I’d like to make a case against it and paint a possible painless and aurally better future.

Engage Tinfoil Hat: Samsung Note 7 Battery Theory

October 24, 2016 by Mike Szczys 144 Comments

For the most part I believe things are as they seem. But every once in a while I begin to look at notable technology happenings from a different angle. What if things are not like they seem? This is conspiracy theory territory, and I want to be very clear about this: what follows is completely fictitious and not based on fact. At least, I haven’t tried to base it on facts surrounding the current events. But perhaps you can. What if there’s more to the battery fires in Samsung’s Galaxy Note 7 phones?

I have a plausible theory, won’t you don your tinfoil hat and follow me down this rabbit hole?

Li-Ion Tech Staring Into The Abyss With Note 7 Failure

October 14, 2016 by Will Sweatman 155 Comments

Unless you’ve been living under a high voltage transformer, you’ve heard about the potential for Samsung’s latest phone, the Note7, to turn into a little pocket grenade without warning. With over 2.5 million devices in existence, it’s creating quite a headache for the company and its consumers.

They quickly tied the problem to faulty Li-ion batteries and started replacing them, while issuing a firmware update to stop charging at 60 percent capacity. But after 5 of the replacement phones caught fire, Samsung killed the Note7 completely. There is now a Total Recall on all Note7 phones and they are no longer for sale. If you have one, you are to turn it off immediately. And don’t even think about strapping it into a VR headset — Oculus no longer supports it. If needed, Samsung will even send you a fireproof box and safety gloves to return it.

It should be noted that the problem only affects 0.01% of the phones out there, so they’re not exactly going to set the world on fire. However, it has generated yet another discussion about the safety of Li-ion battery technology.

It was just a few months ago we all heard about those hoverboards that would catch fire. Those questionably-engineered (and poorly-named) toys used Li-ion batteries as well, and they were the source of the fire problem. In the wake of this you would think all companies manufacturing products with Li-ion batteries in them would be extra careful. And Samsung is no upstart in the electronics industry — this should be a solved problem for them.

Why has this happened? What is the deal with Li-ion batteries? Join me after the break to answer these questions.
