@new weight unit
I'm all for bizarre units, and this one is even better than most in being "small, but massive"(*) all at the same time.
I for one welcome our small and very far away overlords, etc.

re: Metric units are abstract
Well then, I'm sure a litre of water out there somewhere will be very surprised to find that it weighs exactly(*) a kilogram, and that it fits in a cube of 10x10x10 cm. What could be a better and more concrete basis for a shared measurement system than the physical properties of water?
* Well, that was the intention behind the system, but what with measurement error and subsequent redefinitions, the SI measurements for volume, weight and length don't exactly meet this ideal.
The one thing that the French obviously got wrong in their zeal for base-10 measurements was the idea of the ten-day week. Sure, it'd be marginally better to have 3/10ths of the week off instead of 2/7ths, but who wants to have to work 7 days in a row? I guess they didn't take into account that weeks (and calenders) are more of a social construct than a scientific one.
Re: What part of "Denial of Service" don't you get?
"Denial of service" doesn't mean "overspamming".
Absolutely. You could also add a Slowloris-type attack to your list of possible DoS methods. You don't need huge amounts of traffic to effectively knock out a vulnerable server by starving it of file handles for handling legitimate connections.
Re: As with all these Eco stories...
reminds me of King Canute trying to hold back the tide, pointless and above all arrogant.
Except that Canute most likely did it to prove a point (that he did not have the power to command the tides), and not out of arrogance or power-drunk madness. From the wiki page:
It is believed that, on this site, Cnut tried to command the tide of the river to prove to his courtiers that they were fools to think that he could command the waves.
256MB RAM is not much for running a modern graphical Linux desktop
I keep seeing this comment here on the Reg. It kind of bugs me to read that given that the PS3 only has 256Mb of main memory and it's completely capable of running Linux + X/Windows. OK, so there is a slight proviso in that large compile tasks sometimes need just a little bit more swap space, often borrowed from unused video memory, but you could just allocate an equivalent amount of disk-based swap and everything's copacetic.
So--256Mb--it may not be enough for everybody, but it's definitely enough for Linux + X/Windows.

I dunno. You could tape it to the underside of a glass table, attach a couple of joysticks and buttons and use it as a retro gaming station. Provided it's got USB connections and whatnot.
TBH, I don't really have a clue either.

What is a program?
I'm not convinced that whitelisting can really work in real-life situations. While it's impressive that they've committed themselves to building such a large database of known programs, there are a few big problems that I can see.
First off is the problem of what a program is. In this day and age so many packages have programming languages built into them. Either that, or the packages are actually development platforms in their own right. In the case of packages that have some form of scripting included as a non-core feature (spreadsheets, word processing apps), it would seem to be impossible to whitelist every single "program" embedded in ordinary files (shared by people) or included in the standard corporate install image (eg, company templates). The problem here isn't just the volume of programs that would need to be whitelisted if you take this expanded (and more correct) view of what a program is, but there would also be confidentiality issues if your company had to send samples of all your in-house macros/script collections for hashing. Even if you could set up the hashing/authentication server in-house, there's still plenty of scope for cock-ups.
Another problem with malware is that quite a lot of it (perhaps the majority?) is exploiting bugs in particular packages. Almost any program that reads in user data has the potential to have bugs which renders what should be just input data into live code. So even though a PDF or a particular set of inputs to a web-based service ostensibly doesn't come under the rubric of "programs", they do become a way for malware authors to trick the application or server into executing whatever they want. The whole whitelisting philosophy completely fails here since user input, data files, and so on simply don't get counted as programs when actually they are.
I noticed in the article that someone attached to the company said that false positives with whitelisting technology were "bad in the early days". It beggars belief that the people building these systems don't even seem to understand the Birthday Paradox when it comes to picking a hashing scheme... That certainly doesn't inspire confidence.
All in all, as it's reported here, the scheme is pure hyperbole, possibly verging on snake oil. IMNSHO.

re: disk drive (1541 an expensive peripheral)
Yes, that's true, but considering that it had quite a few of the same parts as in the c64 itself (less sound and graphics chips, naturally), the price wasn't that surprising. Basically, it was a fully-fledged computer in itself, albeit one dedicated to working as a drive controller.
I could never afford the 1541, but by the time I'd outgrown the tape drive, some clone drives were available that were a lot cheaper (and more slimline). I bought one of these clones (I can't remember the name, but I think it might have been by Evesham Micros) and never had any problems with it.
With this news, I'm tempted to pull the system out from the cupboard to see if it all still works. I loved playing Uridium and Zoids, but I'm sure there are dozens of other excellent games I've completely forgotten about. I just hope the floppies still work.
Thanks for all those (great) wasted hours and all the memories. RIP, Jack...
Loving the C64-style colour scheme and boot message
And if you squint, the assembly language isn't that far removed from 6510 assembly either. Well, the JSR, addressing modes and limited range of registers look similar anyway. The 16-bit opcodes look a bit bloated and strange though--definitely not like a C64. Then again, A9 30 only stores an 8-bit value there.

Of Simulation and Dissimulation
Francis Bacon's essay of the same title starts off:
DISSIMULATION is but a faint kind of policy, or wisdom; for it asketh a strong wit, and a strong heart, to know when to tell truth, and to do it. Therefore it is the weaker sort of politics, that are the great dissemblers.
Besides still being a relevant observation on the value of privacy (rendered as "closeness, reservation, and secrecy"), it's also telling as an indictment of Bush and Blair. All politicians lie, and we expect them to "dissemble" (pretend not to be what they are) and "simulate" (pretend to be what they are not) to some degree of another, and as appropriate to the circumstances. However, these men have taken simulation and dissimulation to such a level that one wonders if they are the only ones who cannot see their lies as anything but transparent falsehoods. Such people are beyond being merely immoral---they are outright dangerous.

"worse than CUDA with a fraction of the performance"
How do you make that out? Care to mention a bit of hardware that uses CUDA (in a more or less similar price range) and that outperforms a PPU/SPU app? I'm not saying it doesn't exist, but your comment is meaningless without looking at hardware--the programming architectures simply aren't directly comparable. On top of that, you also need to consider what type of application you're running. You can't make a blanket statement like that without considering what problem is being thrown at the system.
While I admit I'm not an expert on CUDA, I would consider myself pretty good at programming on the Cell. It seems to me that it would be a lot more difficult to get anything approaching full utilisation of the GPU in a CUDA architecture in comparison. The main reason is that CUDA seems to be designed around throwing many less powerful compute cores at a problem, and due to Amdahl's laws, there's a limit to how effective this can be, depending on the type of problem. CUDA does seem to be an advance over most previous GPGPU attempts, mainly in supporting a richer set of programming primitives. Bitwise operations is the main one I see, but perhaps it also supports branching? I'm fairly ignorant on this, but I know previous GPU shaders didn't support branching, something that seriously restricted their power from a programmer's point of view. Another CUDA downside is the lack of recursive function calls. There are probably more restrictions I'm not aware of.
On the Cell, on the other hand, the SPUs are much more capable computers in their own right, with a full and pretty rich instruction set. It still has a performance penalty for (unhinted) conditional branches and it's really designed as a vector processor so there's a performance (under-utilisation) hit there too if you're writing scalar code for it. But the point is that it's a much more advanced core. Add to that that you've got great inter-core communication possiblities (hardware mailboxes and interrupts and very high bandwidth DMA, though not directly to the GPU--you have to use a flip buffer in main memory) and it's quite possible to think of dedicating some SPUs to specific tasks the way you would threads or concurrent processes in other systems. Or of using a hybrid model, with some SPUs loading code dynamically as needed for small, compute-intensive kernels, while others are statically allocated to certain tasks/threads.
The Cell is also much better at keeping the main CPU free from having to act as a master to slave cores, with all the attendant housekeeping that can entail. In a properly designed application, SPUs can basically act asynchronously and can coordinate work amongst themselves, with main CPU overhead kept to a minimum. My guess is that a CUDA system needs to dedicate a fair amount of main CPU grunt to keep GPU cores singing. And that's power could be spent implementing other parts of your app that the GPU can't help you with at all.
The upshot of all this is that while a CUDA system could very well beat a PS3 at a narrowly-defined task (eg, password cracking, though not things that involve rainbow hashes, since memory/disk bandwidth is the bottleneck there), such applications generally have to be embarrassingly parallel to begin with. So maybe you can write part of your render pipeline by throwing more cores at it in a CUDA system (constrained by your memory/DMA buses), but because of Amdahl's law, there's a limit to how far that will take you. At a certain point, you need to start thinking of apps as distributed programs with complex data interdependencies instead of purely parallel ones with only simple pipelines, and that's where the Cell's architecture really shines, in my opinion.

Dear Mr. Bank Manager
I was quite shocked to read your letter describing your problems balancing our bank account. I suggest we meet up to discuss same. How does Blackfriars Bridge on the 18th sound?
So mote be it!
PS please bring some bricks, if you can, on the off chance that we may chuck them at the ducks.
I get letters telling me since I moved away
you've taken to hanging out on that rock about a mile from shore
given what I know about that rock mainly that it's populated by seals
I strongly suggest to you that you not hang out there anymore
'cause the seal is a wily and a vicious creature
and the seal will bite you if you give him half a chance
yeah the seal has a mind set on violence
and the seal is the sworn enemy of man
now when I say that the seal is vicious I use the term advisedly
according to webster's 9th new collegiate definition 4b.
which states that vicious means marked by ferocity
and offers as a synonym...savage
'cause the seal is a vicious and a wily creature
and the seal has a mind full of evil designs
and the seal will harm you and laugh about it
yeah the seal is not a creature you want to toy with

Quantum tunneling doesn't necessarily manifest
in the equipment used to etch a pattern on silicon. Quantum tunnelling is how the uncertainty principle manifests as electrons travel along ever-smaller circuits. As you shrink circuits and the overall energy levels approach Planck scale (which might be measured in terms of energy gaps or distance) then it causes electrons to apparently "teleport" at random, so smaller circuits introduce quantum glitches.
If you're talking about the actual process by which circuits are etched, however, you're probably talking about very high energy beams (x-ray lithography or, in this case, an electromagnetically accelerated electron beam) then the energy of the photon (x-ray) or electron (CRT-like accelerator) can be ramped up to a level where they're well in excess of the Planck-scale energy levels, so won't be as affected by the uncertainty principle.
There are still problems, though. Even x-ray lithography (higher energies relative to UV) mightn't have enough energy to cast a clean shadow against the mask--hence (I take it) the need for multiple masks and x-ray sources. As for CRT, aiming is still hard at high energies due to the need to have a very high frequency circuit for steering the electron beam. Aiming has been a problem with CRTs since the beginning. The traditional solution (to get the electron to hit the right pixel) is to have a charged mesh close to the target which helps to focus electrons that are slightly off-target or absorb those that are more wildly off. Higher-energy electron beams probably do something similar.
The designers of these kinds of etching hardware still have to worry about the uncertainty principle as they get to ever-smaller scales, but the physical description of their problems manifests more as wave/particle duality (inability to cast hard shadows due to edges causing a diffusion/diffraction of the beam) than quantum tunnelling per se ("teleporting" low-energy electrons in a circuit). At least, that's how I understand it...
is latency that big a deal?
I can see cases where it matters (basically anything that requires interactivity, such as database back-ends, game servers or things that need to be as real-time as possible) but how many of these are going to be held up by client-side latencies (application loading) or network latencies (things accessed from cloud or web interfaces)? I can also think of many more applications (indexing, compiling, transcoding, rendering, etc.) that are more compute-bound or that would much prefer to have bigger throughput/bandwidth than lower latencies. Besides, in a lot of applications the latencies associated with data transfer can be hidden by doing double- or triple-buffering of work packets or precaching data. This can usually reduce latencies to effectively nil, provided there's a discernible access pattern and it's not just purely random access (which the tiered, "temperature"-based storage caches won't handle well anyway). So does latency really matter so much?
If you have artificial gravity, why do you need Newtonian thrusters?
Maybe because their artificial gravity system is effectively in a bubble with no net change to gravitational forces outside the ship? So like, maybe, the gravity in all the levels pulls in a direction they decide to call "down", but up at the "top" of the ship they've got the reverse pull to balance things out?
TBH though, invoking "artificial gravity" explanations kind of bugs me. We know it's all made up, but there's no need to lampshade it. The one exception: inertial systems that actually work, ie spinning ships and stations, a la 2001.

I know the article wasn't being entirely serious when suggesting it, but dual sim isn't going to allow you to create two walled-off identities. The problem is that the IMEI is transmitted when you register with the GSM system and this is uniquely tied to the phone, not the SIM. So no good for drug dealers, extortionists, kidnappers, etc.
