Re: Quantum computing?
I can't help observing that to get a Fermion back into the same state it started in, you have to rotate it through not 360 degrees but 720 degrees. Are Fermions female? Discuss.
There's satire, and then there's just being a bunch of dicks
Indeed, and this isn't even a patch on Intercal
" It is a well-known and oft-demonstrated fact that a person whose work is incomprehensible is held in high esteem. For example, if one were to state that the simplest way to store a value of 65536 in a 32-bit INTERCAL variable is:
DO :1 <- #0¢#256
any sensible programmer would say that that was absurd. Since this is indeed the simplest method, the programmer would be made to look foolish in front of his boss, who would of course happened to turn up, as bosses are wont to do. The effect would be no less devastating for the programmer having been correct.
It looks like something you'd fill with ice to cool a bottle of wine.
Re: So now all we need..
At the small end you could try a Cubieboard, with 1 x SATA on board. BTW Linux supports SATA port multipliers (forget the exact right term - but like SCSI LUNs on SATA, can attach four or more drives to one SATA port). Might be a fun project.
At the bigger end you could stick with Intel and get an Avoton server with 12 SATA ports. http://techreport.com/news/25703/asrock-combines-avoton-soc-12-sata-ports-on-mini-itx-mobo
There are plenty of whisper-quiet Intel solutions. Start with a low-wattage CPU (think 35W TDP is the lowest). Then research all components with fans. Typically you use a large case with a 12cm fan running at minimum speed and a large-fan CPU heatsink which again will result in the fan running at minimum speed (or off most of the time, if the motherboard is chosen to be capable of running the fan at zero rpm when the CPU isn't in need of any cooling). You can get completely fan-less PSUs. You'll also want to choose hard disk drives with care lest they be the noisiest part of your system. WD "Red" aren't the fastest, but they may be the quietest. I can't hear them seeking at all!
I've been trying to find a mini-ITX board with an Intel i3-4210U soldered onto it and passively cooled (15W TDP) but nobody seems to make that. Annoying. (I have an Atom-based home server which I'd like to speed up, but not at the expense of starting again with an Intel NUC and a 3rd-party passive-cooling case and not at the noise cost of even whispering fans).
Gnome 3.10 ... hopefully yum install cinnamon still deals with that. (Or you could have picked KDE in the first place).
They've already made BBC World Service DAB only (well, apart from AM ... it wasn't ever on UK FM). This is the only reason my DAB receiver didn't get thrown in the trash can.
Re: less than 4 years after the Pearl Harbor attack,
I'd also note that in the intervening four years we also had something the world hasn't seen since: total war
We've seen it many times, just not on the same scale. I wonder how much consolation it was to a Korean or Vietnamese, or is to a Syrian, that most of the rest of the world was / is not likewise at war.
Except, one hopes that the NSA or someone is reverse-engineering the BIOSes being shipped, to keep the other side honest. Booby-trapping all BIOSes shipped is the sort of dirty trick that you could get away with only once (and pay a huge economic price afterwards). Unless you posit a multi-national conspiracy, if it had been happening we'd have heard about it by now.
Unless absolutely nobody is checking.
Re: BIOS malware eh?
It's been around ever since some bean-counter demanded removal of the write-protect switch from a system's flash logic circuitry.
How it ought to be, is that to do a BIOS upgrade you'd start by taking the lid off the system and moving a jumper or switch to write-enable. Then update. Then set it back to write-protect. (Note: nothing to stop manufacturers shipping it write-enabled, if they know that their average customer is a moron. Intelligent customers would protect it on delivery -- or buy from a different manufacturer).
How much did removing one jumper save? One cent? Probably less. Bullet, meet foot.
Why in the thirty-two Hells of Carmack would they want to get into building their own hardware especially at the silicon level?
Because they can see a way to reduce their energy consumption by doing something differently in Silicon? Because of their massive scale, things may look different to Google compared to lesser companies.
What Google really wants?
What Google really wants is an ARM solution fabbed by Intel at 14nm!
Maybe Google is a large enough customer, that Intel might consider fabbing custom chips that aren't sold to anyone except Google. Google could buy any necessary ARM license and have it fabbed by any company willing to take their money.
Also maybe a hybrid chip with both x64_64 and ARM cores is possible and useful to Google.
Another, shorter formulation:
Any sufficiently developed bureaucracy is indistinguishable from malice
Re: FX570 was a superb calculator
I think the Commodore SR-36 goes back a bit further. It had Red LED displays, not LCD (which ISTR hadn't yet been commercialized). Superb bit of kit for the time.
I used mine for about fifteen years, until the batteries faded to the point you could only use it tethered to a wire, and I threw it into a box in the attic. I recently found it and fired it up, but something had failed while it was in storage and it would display only gobbledegook.
Still looks good, though.
Re: A better useful Firefox "extention" [sic]
Invent an algorithm for your passwords.
If you forget your password recalculate My_Algorithm( "Facebook", other_things_that_I_CAN_remember)
It doesn't have to be complicated. You're already ahead of 99% of the crowd. I don't imagine for a moment it'll defeat spooks (who have inside access to Facebook et al anyway). It will defeat the sort of criminal who assumes that all your passwords are likely to be the same, or steals your computer so he can use your stored passwords.
And use a different algorithm for passwords that unlock real money!
Re: Far more than "IT" person of the year
I wouldn't even say that the NSA and suchlike are evil. They're just government agencies and they probably think they are doing good. At present one might credit the governments of the USA and the UK with some degree of good intent, or at least benign intent. But do we all know what is proverbially paved with good intentions?
The road to hell.
There's also the advice about "Power corrupts ...." and I think it's becoming clear that they are stealthily acquiring more power and becoming more corrupt. Yes, for sure we're on the road to hell. How can we get off it?
Re: Fuck Off!
Use a VM. Install Linux (Paranoid version: do not install Firefox or Seamonkey at this stage). Shut it down. Make a copy of the VM. Boot the copy. (Paranoid version: now download and install a browser). Browse. After your chosen time window, blow away the used browser VM, make another copy of the virgin one.
Now, do I trust that NSA hasn't found a way to subvert VMWare player so it can track every VM running in a particular player instance? Or that Browser instances aren't somehow trackable from day one (say courtesy of a secret NSA implant in MS OS'es) with all this Google cookie fuss as camouflage? Of course if the VM host is also Linux, there are lots of alternatives and all source code is available.
the right icon would be a hall of mirrors, possibly with Granny Weatherwax's naughty sister standing between them.

Re: Better Idea
>>Put an end to this stupid millisecond nonsense<<
How? Maybe insist that all trades are input by a human being. Computers alllowed as advisors, but not permitted to enter directly.
Would destroy anything based on high-speed decision-taking and ultra-high leverage. The first, because a human can't input a trade in less than a few seconds. The latter, because the risk from fat-fingering it would be too great.
Just because something can be done does not mean that it should be done. Trading faster than a human being possibly could is one of those things. Doing so with ultra-high leverage puts the stability of our entire financial system at risk.
Re: solar power will be the limiting factor on what humans can do in the long run
Todays nuclear reactors have outputs that reach the MW range on a surface that would take a solar farm half a continent to replicate.
Bollocks! A small fraction of the Sahara desert alone could generate more electricity than the human race currently uses.
The Solar radiation flux onto Earth's surface is about a kilowatt per square meter. Allowing 10% for harvesting efficiency and a factor of two for dark night-times. you need 20 m^2 per kW power-station output. A large power station is a Gigawatt: a million kilowatts, or 20 square kilometers of desert covered in solar panels.
Controlled nuclear fusion would be great if we could get it working (economically). So far, we can't (at all). Certainly worth continuing to try, but ... in the meantime, solar panels really do work, and offer an alternative should fossil fuels become uneconomic or accepted as too damaging to use. Solar panels are already cost-competitive with fossil fuels where there are deserts in close proximity to cities (for example, in Arizona).

Re: Why a hexagon?
Why can't it be because of a years-stable period-3 wave in the planet's equivalent of Earth's jet-stream. Watch long enough, we may see the vertices move, assuming there's anything more stable to define their location relative to (which on a gas giant, I doubt! )

Anyway, it's not new. Since the earliest days of the Chinese Empire (and probably earlier, but the records have perished) there have been trustworthy(*) alternative criminal(**) organisations which would move your money across borders and around accountancy barriers for a fee. Typically you hand over some money and receive a token, such as a roughly torn sheet of paper. You later present it to a representative of the same organisation at another location, and they match the other torn piece and then hand over the agreed amount of cash.(***)
(*) for certain values of trustworthy
(**) according to the authorities, who ask more in taxes than the alternative asks in fees.
(***) this practice may even be the origin of paper money instead of gold, brought back from the underworld by the authorities, who could then back several banknotes with the same piece of gold and get away with it for centuries. Behaviour which any self-respecting criminal gang would be ashamed of.
Re: What goes around...
I wouldn't want to be these crims when they get caught.
Especially if it's organised crime that is first to catch up with them. It's probable that organised crime has also had its data corrupted, and what can they do? Can't inform the authorities. Can't pay the ransom, in case it were a sting by the authorities. Can do something hideously violent and permanent to the perps if they find them.
Re: backups and...
Linux LVM snapshot will preserve the state of the LVM at the time it was taken. Cryptolocker, or anything else not running on the Linux LVM host, could only affect the snapshot if it were mounted and exported read-write. A common practice is to mount it read-only and export it read-only, so users can perform self-service rescue of files they (or cryptolocker) have messed up. RO mount means that only a root exploit on the Linux host can damage it, but then copying the snapshot to offline and offsite storage is a good second-line, not least should your backup volume fail.
One caveat - make sure that the snapshot LVM is the same size as the source LVM so that should Cryptolocker or everything else write to most of the blocks on the source, the snapshot doesn't run out of space.

Re: Calm down...
It's to stop the "flip it over" problem that USB connectors seem to magic upon themselves - Cable won't go in - Flip it over - won't go in - flip it over - goes in.
A USB connector is a Fermion not a Boson. You have to rotate it 720 degrees before it's back in the state it started in.
(A corollary of his is that no two USB memory sticks can ever have the same internal state :-)
Re: Resistance is futile
@Wzrd1 - a fundamental misunderstanding of CMOS. In a pre-CMOS computer, a bit was represented as a flow of current. It's consuming power even if it's just maintaining an unchanging logic level for minutes on end.
in CMOS a bit of state is a package of charge - maybe as little as 100 electrons. No current flows except when a bit of state is chaged, when the electrons have to be removed from a high voltage (probably representing a 1) to a low voltage (0). CMOS can work on micro- or nano-watts. Witness the hand calculator powered by a couple of square cm of low-grade PV panel, illuminated by an energy-saving dim light bulb (and operated by a dimmer one - sorry). Easy when you want single-digit IPS not MIPS.
Moore's law is based on a scaling law. If you shrink the devices by a given factor, reduce the voltage (between 1 and 0) by the same factor, you have constant power per unit area of chip and that factor squared more devices to play with in the same area. The limiting factor is that atoms are discrete, and today we are at the point where the gates of the FETs can no longer be made much (if any) thinner. So the scaling law can't be followed any further, and the first sign of trouble is that the chip runs too hot because it's suffering resistive heating from various sources.
At a guess they aren't stable. AFAIK there are NO silicon or germanium analogues of aromatic (C6-ring-based ) hydrocarbons. In fact I don't think there are Silicanes either, apart from Silane. Instead you get silicone chemistry, based on Si-O-Si bonds.
But I may be wrong, because I'd have thought Stanene even less likely. Is it really stable in the presence of Oxygen? Water? Or is it like one of those "things I won't work with" (Google that phrase for some fun reading about molecules that fall apart at the slightest nudge -- or occasionally, against all expectation, that don't).
Re: Tin pot
Graphene was a neologism
A logical one. The multiple-ring hydrogen-carbon compounds with delocalised electrons have names ending -ene (Napthalene, Anthracene, Pyrene, Benzpyrene ... getting more carcinogenic as they get bigger )
So the one that's so big you can peel it off a lump of Graphite with Sellotape was christened Graphene. Until someone did that, it was wrongly assumed that it would be unstable and couldn't exist. (I'd have voted for Sellotapene)
Re: 100 percent efficiency?
I expect they mean it superconducts only at isolated edges. Pack a load of edges close together and they simply aren't edges any more. The electrons in one edge start interacting with those in other edges and I'd guess the whole thing becomes an ordinary resistive bulk conductor on the macro-scale.
There's a similar problem in the Semiconductor industry. SiO2 is a good insulator, but only in bulk. As you start trying to make thinner and thinner FET gates, you eventually get to the point where most of your SIO2 is surface and the rest is influenced by being only one bond away from a surface. At which point it ceases to be a good insulator and Moore's law runs out of road.
Another similar conundrum is the tensile strength of a carbon "buckytube" molecule. Strong enough to build a space elevator ... except how do you assemble buckytubes into a bulk material? What "glue" can you use, that doesn't change the (admittedly large) molecule into something else?
Re: No, the -ene ending is entirely inappropriate.
Given that there's no carbon and no double-bonds in this entirely inorganic new material, the suffix is completely incorrectly used.
Not exactly. Chemists break those rules all over the place (for lack of syllables? ). -ane refers to a hydrogen-saturated compound of carbon and hydrogen, except we have Silane (SiH4) Borane (BH3 ... sometimes ... lots of other wierd BmHn compounds), and even, if memory serves, Stannane (SnH4). There's the clue: Tin is a group IV element and although it usually displays metallic character, in this -ene it seems to be displaying the same delocalised electron bonding as Graphene.
the thing that's puzzling me is the Fluorine. Two Flourines per Tin should tie up two electrons, so is it maintaining a delocalised ring structure with 2/3 electrons per "bond" rather than 4/3 as in Graphene? Doesn't that make it perfluorostannane? (And can one manufacture perfluorographene, which might make PTFE look sticky if it can exist at all? )
Outsourced / offshored?
Unless, of course, it's outsourced and offshored, so that if someone is "fired" he just gets swapped with someone making a mess of some other organisation's IT. If the entire outfit to which it is outsourced is "fired" the same principle will apply: you'll end up with someone else's rejects, either directly or indirectly (though mass hiring, firing, and forming new companies to tender for the work)
Outsource the catering and the cleaning. If it's mission-critical it must be done in-house. If it's mission-critical and it fails because of under-investment, the CIO (and possibly CEO, rest of board) should be taken out and shot.

Re: "nothing illegal to be wearing Google Glass"... yet.
Out of interest, a 'complete halt' as opposed to what other kind of halt?
Stop-start nudging forwards at walking pace or less in a motorway traffic jam? Seriously, that's one situation in which I defy UK law. If the motorway has been at an all-but-standstill for >10 minutes, I'll call ahead on my mobile to let folks know I'll be late. Which is illegal, because my car isn't parked. Also difficult, because all the other cars are also doing it, and overloading the local cell!
Not relevant to this thread, but I've also had it explained to me by a USA cop that a STOP sign means that one must bring one's vehicle to a completely stationary 0mph stop. Slowing down to less than walking pace and seeing clearly that there's no reason not to turn right (like a left in the UK) is illegal. Only reason I didn't get a ticket and fine was being a newly-arrived foreigner. The law is probably the same in the UK but here a STOP sign is used only on a junction with truly terrible visibility where you would be mad not to stop anyway. Otherwise it's just a "give way". In the USA just about every junction has a traffic light or a 4-way stop.
It is a conspiracy, in that there are public plans to deny us choice by discontinuing FM broadcasting at an unspecified future date. Until an announcement is made that FM is here to stay, be very afraid for your music broadcasting.
Once that announcement is made, expect DAB to die out. The only reason it got any market penetration at all, was a lot of people bought a DAB set to try it out on the back of a load of media hype. (This customer hasn't binned his DAB set because it does represent a slight improvement over BBC World Service reception on AM. The other preset buttons remain unset).
And the funny thing is that your FM receiver doesn't notice. That's right, FM broadcasting is far less vulnerable to interference than digital broadcasting.
(That LED light is faulty, though. Or a cheap illegal import that doesn't meet EC RFI requirements)
Re: Yes, digital is always better than analogue
The problem is with the data-compression used by DAB (and compressed MP3 etc), and the fact that the algorithms chosen generate time-varying non-harmonic distortions. Digitisation, as used on CDs and studio-master recorders, doesn't do this to any audible extent.
Vinyl, valve amplifiers, and carefully constructed nonlinear transistor amplifiers generate harmonic distortion, which colours the music. Some people prefer it that way. I don't prefer it, neither do I detest it. At low levels, without the ability to compare sources with and without low-harmonic distortion, it's impossible to tell whether the tonal colouration was there on the master or not. Draperies etc. in concert halls also colour the music, by removing greater or lesser quantities of harmonics.
If the only source of broadcast music is DAB, I'll never listen to broadcast music again. What it does to music (even with perfect reception) is simply vile.
Re: Radio Silence in Cars ?
Fuck DAB till it has a genuine 95% saturation rate. Until it gets that far, it's useless
And even if it does get that far, it'll still be useless. I'll just have to stop listening to radio, and spend a bit more time compiling my own zero-compresion music collections.
Re: Quote "XP is like 13 years old. Get with the 21st Century."
If a stalker knows enough about me to impersonate me to obtain my vehicle's location, they likely know where I live already as it'd be one of the security questions so why would they go through the hassle and risk of exposing themselves further?
That might be the point. Someone you want to avoid, doesn't know your location but has access (legally or otherwise) to various large collections of data.
The other reason is that an automobile "accident" is much easier to arrange and much less likely to lead to a full murder enquiry, than any other sort of "accident". And the more they knew about your habitual routes, the easier it would be.
All hypothetical. Some people care about their privacy more than others.
Re: Quote "XP is like 13 years old. Get with the 21st Century."
Clearly you're lacking some knowledge on how these trackers work, they do not report your every move, you report the vehicle stolen, the company that provided the tracker contact the car and retrieve it's location.
At the risk of posting something that really belongs on the Snowdon thread, why on earth do you trust that the tracker company is the only organisation that can do this, and that it would never do so on anyone's behalf except your own?
All I can say is I hope you never have to live in fear of a jealous wife, a new partner's wealthy psycho-stalker, a criminal organisation that wants to erase an inconvenient witness before he can talk, or a government run by a mega-humanitarian like Joseph Stalin. (Mega-humanitarian: eats people by the million).
Re: More on win8 please.
any new laptop purchased now is going to come with win8, I'd like to know exactly what evilness MS has in store for those of us who want to dual-boot linux.
Make those restore DVDs as soon as you've unpacked it. Then make another set just in case. Assume that your first attempt at converting it to dual boot will brick it at the software level, and then you can only be pleasantly surprised. (Unless you manage to brick the hardware - far too easy on certain Samsungs, supposedly now fixed in the BIOS. They blamed Linux until someone demonstrated you could also brick one trying to dual-boot two versions of Windows).
Use Google. Read about the generics, and as much about the specifics of your model as possible.
It's probably running in secure boot mode as shipped. This can be turned off, from within Windows 8. I'd recommend that you do. After that you just have to master re-partitioning a UEFI disk, installing Linux into UEFI partitions, and installing Grub2 or other boot manager. Alternatively you can have "fun" trying to install a secure-bootable version of Linux.
The quick and easy way for casual Linux usage is to download free-beer VMware player for Windows and run your Linux inside Windows. (Yes, I know, leaves you feeling unclean just thinking about it. But easy) The other way around requires paying Microsoft more dosh for a retail Windows distribution (or playing fast and loose with your employer's volume license ... which might just cost you your job so don't.)
Sorry, I'd forgotten Vista. Wiped it completely from my mind, or maybe Microsoft brainwashed it out of me. Though in my defense I could assert that Vista was just a Windows 7 RC, which should never have been sold or even shown to the world.
And was/is Vista more resource-heavy than 7? My impression of it was that it was buggy and brain-damaged in equal measures, rather than that it would have been OK given 4Gb RAM and a CPU speed boost.
Re: massive blackmail database being compiled...
The scary thing is that "big data" techniques mean that the database does not actually have to be compiled. They can just do a search for dirt on anyone who is deemed to be a legitimate target, through just about everything that's ever been recorded about everyone. The NSA is filling a data centre mot much smaller than Wembley Stadium with 4Tb disk drives. We're all in there. If you've had an extramarital affair in the last decade, I'm fairly sure they can work out when and with whom, just as soon as they get the order to look for dirt on you. If you have one this next decade, it will be a dead certainty they'll be able find out.
I didn't really get "Rule 34" when it came out. When I first read it I thought it was for laughs. Now, it's starting to feel as chill as the bad stuff in the Laundry, and a lot closer to real life. Skynet is unlikely. ATHENA, on the other hand ....
Ad hominem attacks are OK by me when they consist of revealing that someone is a hypocrite. Because a hypocrite is someone who should be attacked for what he is. The adjective "nauseating" is often applied, because any decent person will be sickened by anyone who preaches one thing in public and engages in its opposite in private, regardless of whether they support his public position or oppose it.
