...nobody in real life could afford four of Dr Grordbort's Infallible Aether Oscillators.
(Although the one they're playing with in the video looks like the Righteous Bison, which is the budget model at a mere $100. Probably because when they were filming it they were afraid it'd get dropped.)

To be completely frank (which I'm not, my name's David), the thing I liked best about the HL series was the story. Which was interesting, and varied, and had some characters I really liked, and did a really, really good job of immersing me in the good but fairly abstract FPS game mechanics.
You don't get stories in multiplayer. Sometimes they can pretend there's a story, but it never really works.
I want to know how it ends. Years later, I'm still emotionally invested in Gordon (even though his entire character is inferred from the reactions of people around him!), and Alyx, and Barney, and Dr. Kleiner, and Eli, even D0g, Hedley Lamarr and the G-Man. I want to know how it ends, dammit, especially after the HL2e2 ending (which I am still pleased at having played unspoilered). I want to know more about the Combine and find out what they really want, and see their homeworld (where I'm sure the inevitable climax will be). I want to know who the G-Man really is. I want to know more about the vortigaunts (and hear them talk, which never fails to be hilarious). Basically, I just want to know.
Having a good game would be a bonus too. But mainly I just want the story.
I am curious how that tiny antenna can produce enough energy to drive even a crystal earpiece. Most crystal radios need huge antennae, don't they? And from the writeup it looks like the FM decoding more or less happens by accident as a side effect of signal interference.
If this really works, I reckon it should be possible to build a miniaturised FM crystal set into a pair of headphones. I wonder if you could do stereo?
You can get batteryless radios. Crystal radios (which don't necessarily contain a crystal) get all their power from the radio signal, and they're scarily simple. During the second world war foxhole radios were built out of a razor blade, a pencil, some wire and a set of headphones (instructions: http://www.bizarrelabs.com/fox...) Prisoner of war radios used coal
AFAIK, however, the much lower energy VHF signals for FM isn't capable of running an FM decoder, and probably not an earpiece either.
I wonder if a modern crystal earpiece could usefully pick up low-power AM transmissions from a cellphone in your pocket without spamming everyone around you with radio waves?
The compositing of effects onto live action was laughable --- you could tell when a scene was going to have CGI in it because it would suddenly go fuzzy as they dropped the resolution.
And at least in the first season, the choreography of the space sequences was incredibly stilted (Starfury moves onto screen right-to-left. Starfury comes to a halt in the middle of the screen. Starfury does a 180 degree turn and stops. Starfury fires cannon. Staryfury does another 180 degree turn. Starfury exits screen right-to-left). But that was because they simply didn't know to use technology properly, as CGI was brand new and they were basically making it up as they went along; they learned on the job and later seasons were pretty good.
...I wonder what happened to all their digital assets?
I just moved to Zürich from the United Kingdom. It's absolutely true --- kids will just randomly wander around on their own. Here, it would be considered weird for a six-year-old child not to go to school on their own, particularly if it were only a mile away.
One of the things that helps, I think, is that the culture here allows random adults to talk to random children. (Or, more accurately, the other way round, frequently incessantly, in Swiss German, which I don't speak.) If one gets lost, which is very unlikely given the amazing public transport system, they can just ask. This is very weird to someone from the UK, where it's pretty dangerous to even make eye contact with someone's child...
A rocket ought to be fairly resistant to bad weather --- they have many more times the control authority that an aeroplane has, due to sodding huge engines, and will be above it very quickly. They already have to deal with very strong winds blowing them sideways as they pass through the jetstream (at 100km/h plus), and they don't have air intakes to suck in rain.
Does anyone know whether the Falcon 9 can't take off in bad weather, or whether they won't do a launch in bad weather because they'll lose visual contact with the vehicle, which is critical for monitoring the performance of what is fundamentally a prototype?
...is a Debian userland on top of the BSD kernel. It lets you use all the tools you're used to while also getting all the FreeBSD kernel goodness, like in-kernel ZFS, etc.
It's still a work in progress and not all packages are built for it, but it works really well and is very pleasant to use; plus you get dpkg and apt.
Of course, one possible downside is that you don't get the BSD userland, which has a flavour all of its own. Whether you think this is a good thing or a bad thing is purely a matter of personal taste.
For me it was Nicholas Montserrat's The Cruel Sea. A brilliant, brilliant book, but it was clearly written as therapy after a hellish time on the WW2 North Sea convoys, and by god it shows.
Peter Grant books: awesome, waiting for Foxglove Summer to show up. The Expanse: pretty awesome, although the authors have definitely been reading their Neal Asher; who these days pretty much defines the cheerful big-things-exploding-in-space genre.
Never heard of Scorpion. Never heard of the guy in the article. Sounds like I haven't missed much. And if you'll excuse me, I need to get on with Ancillary Sword...
Android devices have a read-write partition and a read-only partition. Out-of-the-box apps go in the read-only partition. There are several reasons for this, one of which is safety --- you can nuke the entire read-write partition and be sure of (a) getting a working factory reset phone and (b) that all user data has been deleted.
If an app's in the read-only partition, then it obviously can't be removed. (Although you can install updates --- the new versions go in the read-write partition and override the read-only one.) All you can do is mark it disabled.
(Of course, if you've rooted your phone, you can remount the read-only partition as read-write and tinker with it to your heart's content. I do this to move updated apps into the read-only partition to save space in the read-write partition. But that only works on rooted phones.)
If you're interested in Z80 operating systems, go look at CP/M (seriously: get an emulator, some tools, and write programs for it). It's a fascinating look into just how minimal you can make an operating system and still have something that's not just functional but which spawned, back in the day, a vast ecosystem of tools and software. You suddenly realise just how much fat there is in a modern system (and also why modern systems have all this fat).
I rather like the StackOverflow moderation system, where it costs _you_ karma to downvote someone else.
In general, I don't think Slashdot's moderation system is effective at promoting interesting discussion. I think the bulk of the problems are the moderation cap at 5, which means there's a very limited dynamic range of interestingness; and there's no visible karma score, which means there's no point in taking the long view --- StackOverflow's system of gamifying karma so that people deliberately try to post good stuff so as to improve their score is total genius.
Plus, of course, the now-ingrained culture of ultra conservatism and whiny hate which permeates the comments section, but that's largely an artifact of the above. Sheesh, even Youtube comments can be better.
That's happened to me. I have a Macbook Air; it's kinda sharp on the front. The person in the seat in front dropped their seat back really abruptly, with the result that I ended up getting guillotined in the gut by the edge of the laptop. It was painful.
I forget which airline it was --- possibly Swiss; I doubt it was Easyjet, as their seats don't recline.
You can actually get cables with a USB A connector on both ends. Yes, they're abominations of nature that make about less electrical sense than a mains cable with a plug on both ends, but you can actually buy them. They're typically only needed one some idiot who doesn't know what they're doing designs a piece of kit with the wrong socket. See, for example: https://www.sparkfun.com/produ...
I have one right here on my desk. It connects a cheapo (but effective) battery charger to a USB power supply. The charger has an A socket, and it connects to a standard charger via an AA cable.
I keep meaning to superglue it into the charger to prevent someone connecting two of my computers together and something horrible happening.
What happens instead is that people latch on to some irrelevant detail in your context and the discussion gets instantly derailed in that direction, thus ensuring that your question never gets answered. It's particularly fatal to mention motive, because that's completely subjective. The only way to actually get useful answers to questions these days is to trim the context as ruthlessly as you possibly can.
One day someone needs to write a "How To Answer Questions The Smart Way".
I suspect the reasoning is that one physical copy == one license. By having the physical copy tied to you, by putting your name in it, they ensure you can't pass it on to anyone else, which means the license becomes non-transferrable. That means it's safe for them to give you a digital copy of the book, covered by the same license, in the knowledge that nobody else can claim a digital copy from the same physical book, without buying a new copy.
I would also be entirely unsurprised if each ebook was personalised, containing the image of your signature, so that if you gave a copy to someone else they'd know. I also see no mention of DRM (but the FAQ mentions using Calibre to convert ebooks, which suggests they don't use it).
The Videocore IV on the Raspberry Pi (which totally kicks arse, BTW, it's a beautiful, beautiful processor. Did you know it's dual core?) currently doesn't have an open source compiler that's any good[*] which I'm aware of. I have tried porting gcc, and got a reasonable way into it, but ground to a halt because gcc. I know another guy who's similarly about half-way through an LLVM port. And Volker Barthelmann's excellent vbcc compiler has a VC4 prototype which makes superb code, but that's not open source at all.
Without a compiler, obviously the source isn't much good, although the VC4-specific code is really interesting to look through.
In addition, having done a really brief scan of the docs they've released, this isn't what the article's implying: what we've got here looks like the architecture manual for the QPU and the 3D engine. The QPU is the shader engine. Don't get me wrong, this is awesome, and will allow people to do stuff like compile their own shaders and do an OpenCL port, but I haven't seen any documentation relating to the VideoCore IV processor. The binary blob everyone complains about runs on that.
It does looks like the source dump contains a huge pile of stuff for the VC4, so maybe they're going to release more later. But even incomplete, this is a great step forward, and much kudos to Broadcom for doing this.
[*] I have done a really crap port of the Amsterdam Compiler Kit compiler for the VC4. It generates terrible, terrible code, but I have got stuff running on the Raspberry Pi bare metal. It's all rather ground to a halt because there's still a lot of stuff to figure out in the boot process, but interested parties may wish to visit http://cowlark.com/piface.
This move makes absolutely perfect sense. Soon, everyone graduating from Kentucky high schools will have above average academic qualifications. Also, the senator is a genius and extremely good looking.
...actually, I misread the chart. GEO is 3.8km/s from LEO. Lunar orbit is 2.4km/s if you transfer from GEO, giving a total of 6.2km/s. If you go straight from LEO to lunar orbit, it's only 4.1km/s... barely more than GEO. So, yeah, I reckon a technology demonstrator is definitely doable right now.

Apparently it uses 1.5mW at 1V.
