Embedded has become a rather broad space these days as the range of computing hardware that's built into other devices gets more powerful at the high end.
Like the GP I think I'd usually prefer to think of a "systems language" as something that's suitable for kernel programming and for the low cost / simple CPU end of embedded work, where things can still be very highly resource constrained. But I can see why they're calling Go one, since I'd also expect a "systems language" to be suitable for writing OS utilities, servers, databases, etc - which Go probably is indeed suited to.
I do still hope we'll one day see a favoured C replacement emerge - one that has similar characteristics and abilities but which is nicer to code in. Not that C is bad at what it does - for the sorts of tasks it's good at it's still really quite good...
The hardware acceleration for video on the board is actually quite impressive. It can apparently decode 1080p video in real time, so even if it can't run a modern desktop very fast it can still be useful; there's a port of XMBC so you can use it as a media centre. You have to have proprietary drivers for the graphics acceleration but it's still cool. I'm not sure how integrated into the normal X11 stack these drivers are by now, earlier on in the project you'd just use the graphics library provided and drive the screen without X (as I understood it).
Yes - this! Actually, I'm not bothered about money staying in my own country or region so long as I know it's eventually going to people who play fair with their workforce. We've had a Fairtrade movement for things like coffee and chocolate - and it's starting to become more mainstream for things like clothing. But it's *very* difficult to find anything technology-wise that has any such guarantees.
I bought a cute little webcam from these guys: http://www.unitedpepper.org/ because they claimed to make it under fair trade-type conditions. It's maybe not the most technically sophisticated but it's a nice little thing and I really wanted to support a company that was trying to make a positive change.
Either way, I've got the money and I'd pay any reasonable premium for an ethically manufactured product, possibly a quite significant premium as long as they didn't make a shoddy device to cut costs elsewhere. But the industry currently isn't giving me the chance to give them that extra money, which seems a great shame.
I do make a point of researching welfare conditions before buying electronics and I often also write to companies before buying Far East manufactured goods. Often they don't respond - but at least they see some public interest. Plus I know that the ones who do get back to me with useful information are worth giving money to.
Maybe publishers should start paying gamers royalties for second hand sales? Every time a gamer manages to sell a second hand copy of a game with one-use DLC, that's a sale that the publisher hasn't had to spend money marketing. The friend he sold to will buy the DLC, so the original owner should get a cut of the marketing money saved.
That's on top of a discount for single-use games, obviously - and the right to compensation for time wasted when buyers find out their game has single-use content and return it for a refund.
I don't really think freedom of contract is sufficient to justify what the publishers are doing in this instance - for general societal well-being, there is law in place that governs contracts in ways that minimise what you might call consumer "surprise". So there are some things you can't put in contracts, a general principle that the party has to know they're signing up for it, etc. Enforcing these helps us in ways including having a freer market because companies can't use the legal system as an alternative to in-market competition. As this practice becomes widespread I think it's certainly inviting heavier government regulation - and I hope lawmakers will make steps towards intervention if it carries on, at least so that the industry makes a more serious choice about what's best.
As described there, doesn't that primarily involve border crossing? Or does it authorise the police to check anyone's origin in case someone's managed to sneak over the border illegally?
The death sentence could be carried out imminently.
Saeed Malekpour was in Iran to visit his gravely ill father. He was waiting for Canadian citizenship and the Iranian regime are aiming to make an example of him, having tortured him and denied him due process. I think the Canadian government does have a particular moral duty to stand up for him under the circumstances, although really all democratic governments ought to oppose this sort of thing.
The Iranian regime seems to have an interest in intimidating the population (and making an example out of cases that are highly-publicised internally, such as this one) since there's an election coming up in March, as well as the general interest in keeping the population scared.
Wow, I've been a bit surprised by the criticism I've seen here. When I saw this I only thought "Getting to the pole: cool" "Riding bikes: fun and fast", so trying to combine the two just seemed like a nice idea. She's also intending to use kite skiing. It's not as impressive as trekking with less equipment, although equally it sounded like she's doing it alone, which is quite scary regardless. It will be interesting to see whether using this level of fairly basic technology helps, hinders or makes no difference.
That's true. I think there'll still be a place for these as separate boards though; for the educational and hobbyist markets (which I think is what they're targeting and expecting to be popular with) it's quite important to be able to easily replace broken devices and to be able to incorporate them into other designs.
Indeed - it looks like it's reusing a load of artwork from KDE *which is good*. With open source there's no reason not to slot in existing professional artwork straight away in a new project. They're even planning to make it easy to contribute their patches to common code back to KDE, so they're even being actively co-operative, which is always nice to see.
If they come up with something that looks nice and is lighter-weight than KDE then I might want to install it on my ancient netbook or in virtual machines. KDE is still my preference on my desktop.
Qt is a nice toolkit and it's good to see more development based on it. There's also the Trinity Desktop Environment, for folks who want a KDE-like lightweight desktop - it actually *is* KDE 3, further developed. It looks like (https://wiki.archlinux.org/index.php/Trinity#Trinity_Build_Dependency_PKGBUILDs) that's based on Qt 3, whereas Razor-Qt can presumably use newer Qt versions from the start. Variety is nice, it's all cool.
This! I live in a bicycle friendly city and generally use my bike to commute. But even here you see people on their phones in cars on a regular basis (which is actually now illegal here), plus trying all kinds of crazy driving when impatient or not thinking straight. When you're cycling it's much more easy for one of those incidents to turn into a serious injury, since you have no protection at all from other people's vehicles.
But people don't have the mindset that they're operating a dangerous machine that they need to take responsibility for, so they just carry on doing it because they don't believe they're doing anything dangerous. I wish people would be taught more explicitly just how dangerous their car is.
With cyclists the situation is complicated because there's an eternal tension between what the two kinds of vehicles think they should be allowed to do on the road. But it's the same if you're driving, no matter what you do, some other folks either think their car is a toy or that nothing could possibly happen to them.
The Island of Sark was, until fairly recently, the only remaining feudal state in Europe. Not that long ago they did have an actual referendum and decided to stay like that, rather than transitioning to democracy (some time later they had another referendum and decided to make the change after all).
Its a tiny, tiny place - cars are illegal, you use bicycle or cart - so I imagine there genuinely *is* an argument that you know the people in power personally, so why would you need elections. Presumably the first time round they just couldn't see the benefit of democracy in their particular case. Not the same scale as, say, Egypt but it is a valid case of where there were sane arguments against democracy.
Tangent: when they did switch, the democracy was apparently under immediate attack. Some UK newpaper barons from neighbouring island (the Barclay Brothers, who own the Telegraph newspaper) threw their weight behind the democracy campaign and put up a candidate. They have subsequently been accused of using their muscle as a local employer to punish and manipulate the population (who voted for someone other than the Brothers' preferred candidate). A thoroughly surreal situation and bizarre to think of a state the size of a very small town / large village immediately under attack by commercial interests and pressures!
Good point. However, I do worry that it seems like the kind of thing that sets a high barrier to entry for new competitors and could generally end up being bad for the market. The big players presumably still would compete with each other over features, but if a new company that didn't have many relevant patents themselves wanted to disruptively compete in the same market (e.g. offering something drastically different in terms of price / business model) then they might have difficulty in licensing the essentials from the big player.
Not that they couldn't already get stomped by the big players in the current circumstance but at least there's no co-ordinated way in which the big players can do so, they'd all have to decide it was worth a lawsuit.

In my experience Nexuiz and UFO:AI have both been quality Open Source games, although I think UFO:AI contains some media that are not categorised as fully Free in the strictest sense. Xonotic looks to be doing some cool new things and I hope that UFO:AI has also improved since I last played with it.
I got one; I've generally heard it called a "BC wheel" or an "Impossible Wheel". Could never get the hang of riding the thing - with a normal unicycle (or even its cousin the Ultimate Wheel) you can put pressure on the pedals to stop the unicycle whizzing off and leaving you to fall to the ground. With a BC wheel you just have to balance incredibly well - it's hard. Some people (often younger people, I think) can pick up the balance quite quickly.
I like seeing unicycles mentioned on Slashdot because balance sports generally seem to be enjoyed by tech-minded people. I suspect it's because they can require an intense but non-intellectual concentration - and possibly because they are non-competitive, unconventional and still easy to enjoy even when there's nobody else to join in.
Same negative marketing smack talk. Also, enjoy the irony that expensive phones are apparently now good, and cheap is bad. (although, of course, cheap isn't the same thing as inexpensive - it really *is* good to be neither expensive nor cheap).
I think more systems these days have IOMMUs, which allow much better protection of DMA accesses by devices. So maybe they can properly address the DMA issue - once operating systems guys get round to it, anyhow.
Agreed that Python is similarly terse, that's one reason I like it. But static typing does eliminate a whole class of errors if done properly. The ML family and Haskell languages do have an amazing static type system, which provides guarantees that I don't have when I program in Python. It's more powerful than the type systems of other statically typed languages whilst being not verbose.
To a large extent, for some functions, when something got through the ML typechecker correctly I generally found most of the bugs were already gone.
The RPython language, which is used by PyPy, does do type inference and then static compilation. I'd quite like to see how good the type checking in that is, as a programming tool.
Part of the problem there is in the teaching of it though; my university taught Standard ML and almost went out of their way to avoid teaching us how to write anything in it that would be useful in the real world. There are some quite practical real-world software packages written in ML / OCaml / Haskell. Plus I find functional-style constructs incredibly useful to sprinkle in Python code I write.
Bizarrely, it's starting to feel like the old Flash Gordon / old cartoon style "rocket ships" are actually the future! I'm not sure I'll ever be able to see them as "retro" and less futuristic-looking than the shuttle, no matter how much more advanced and practical they actually are.
Well, that's the price some designs pay for power efficiency - various ARM implementations make this tradeoff too, which is admittedly a nicer architecture than Intel's stuff and offers good performance per watt. (http://stackoverflow.com/questions/4072183/which-arm-architectures-have-out-of-order-execution). Depends on the characteristics the design needs; for a workstation, in-order would generally be sub-par.
In fairness, for some of the dense, massively multithreaded stuff that SPARC has been targeting in the last few years, in order execution gives you some power and transistor budget savings. Compare the Intel Atom, which ditched the out-of-order capability of their other mainstream processors.
But I was surprised to learn that Sun hadn't previously done out-of-order SPARC, although apparently Fujitsu have.
I'm actually surprised by the reaction since I was under the impression that rights holders for Star Trek (and Star Wars also!) had generally had a policy (possibly even officially) of tolerating fan-made stuff and even fan reuses of their copyright materials within reason. I'd not have expected the tricorder app to be any worse than other stuff that's gone by - but others have mentioned that there are multiple rights holders on Star Trek stuff, so maybe some new people are involved now...
A government which doesn't give bailouts probably has to be one which doesn't allow bailouts to become necessary - which, to me, implies some regulatory intervention that few people are really going to relish.
