Denmark Faces a Tricky Transition To 100 Percent Renewable Energy

squizzar Re:Home storage (488 comments)

Been to Wales? You'd be lucky to get 10% in the summer!

But seriously, based on a quick stab at the numbers from the met office you get 1700 hours a year in the sunniest parts of Wales and 1200 in the least sunny. That's between 13% and 20% across the whole year. So less than 15% in the Winter seems pretty likely.

PC Cooling Specialist Zalman Goes Bankrupt Due To Fraud

squizzar Re:Auditors, auditors (208 comments)

I agree no system is perfect, but to some extent that's the job of enterprise risk departments in auditing firms: They look to determine who has access to the accounting databases etc, whether those accesses are logged and traceable and so on. They also look for discrepancies in the way those databases are managed and if they find them are obliged to recommend a more thorough financial audit rather than relying on electronic systems. If the entire company is systematically deceiving them then there's little anyone could do (other than whistleblowing).

The biggest problem with auditing is LLPs: Once upon a time they were personally and professionally liable for their work. If they failed to audit something correctly they were liable for a huge amount of damages, and because of that had an interest in ensuring no-one deceived them. LLPs reduce if not remove that liability (the personal liability of partners in the company at least - the company as a whole may still be liable I guess) and so there is less danger if they mess up. Couple that with a competitive market that means an auditor who finds too many problems will likely not be getting the contract next year in favour of a more 'flexible' competitor and you don't have an environment that encourages rigorous and cautious auditing practices.

College Students: Want To Earn More? Take a COBOL Class

squizzar Re: The UK Cobol Climate Is Very Different (270 comments)

Well buddy you and any job you have can go fuck itself. My particular job requires an engineering degree - in itself requiring a high degree of literacy, numeracy and the discipline to study those subjects. It requires that I understand a wide range of complex technical subjects, that I can analyse things that have never been done before, can effectively and accurately devise ways to design, implement and test those things. I will work long hours for no extra reward in an area that frequently has hard to measure outcomes and progress projects which can take years to reach a prototype stage. If you're planning to hire me solely because I can shave and buy a suit then I have no desire to work for you. Oh, and if you want someone who does what I do and is good at it... well I'm afraid it is you who is in the queue, not me.

New Release of MINIX 3 For x86 and ARM Is NetBSD Compatible

squizzar Re: Self-healing drivers (93 comments)

Spoken like someone who has never jammed up a PCIe bus before.... driver mistakes can make systems go down hard. Even if the IOMMU is protecting the memory the underlying hardware might be flooding the bus with junk, or in some other unrecoverable or unmanageable state that requires the hardware to be reset. If the host has a way of driving the reset line to the device then you might get out of your bind but that's a long way from stateless - it would let you restart the hardware device without interfering with the system though. That said I don't think there's that much stuff out there that's robust enough to deal with crazy situations like that

Hitachi Developing Reactor That Burns Nuclear Waste

squizzar Re:It's mostly a USA problem (200 comments)

Well seeing as the US government took a huge amount of money from the nuclear generators over the years to fund a waste storage repository (which they are being sued over because of their utter failure to hold up their end of the deal) perhaps they could use that to pay for reprocessing? The electricity producers (and in turn, therefore, consumers) have already paid for it, taxpayers don't need to be involved.

How the Ancient Egyptians (Should Have) Built the Pyramids

squizzar Re:They made the blocks into wheels (202 comments)

Or grooves would work maybe? If you had your rope as one large loop you could wrap it around the whole block a couple of times and then pull the rope from the top - the tension in the rope should hold the cradles in place and you can just pull continuously on the rope to move the blocks. If you were being really clever you could presumably put a second smaller roller in front with the same setup repeated to gain some mechanical advantage.

People Who Claim To Worry About Climate Change Don't Cut Energy Use

squizzar Re: user error (710 comments)

They do have smaller gallons though: 31 US MPG is actually 37 UK MPG, which is not too bad for a 525 - beats my 99 2.8 A4 which does 30 most of the time (but then I use it very rarely, so I accept the cost of fuel as the trade off for having a very nice car for very little money as most people don't want something that thirsty).

The 320d is a wonderful machine - my partners 05 one does around 47 with some relatively leaden-footed motorway driving - could get it to 50+ with some caution.

Harvard Study Links Neonicotinoid Pesticide To Colony Collapse Disorder

squizzar Re:Who would have guessed? (217 comments)

There's an awful lot of stuff you could make from plants that isn't exactly 'friendly' if used in high enough quantity or concentration. Reduction ad absurdum: Crude oil is simply the remains of zooplankton and algae after heat and pressure has been applied for some time... would you spray a field with it? Just because it's from a 'natural' source doesn't mean it's harmless.

Did the Ignition Key Just Die?

squizzar Re:If not... (865 comments)

In a modern car with fuel injection and electronic ignition? The kill switch can kill a number of components quite easily to stop the engine. Just using !kill as an enable to the signals that tell the injectors to open would be enough. For redundancy you could also make sure that the low-voltage side of the ignition coils is masked with it. For complete safety you can block the fuel pumps as well.

SEC Chair On HFT: 'The Markets Are Not Rigged'

squizzar Re:Not a surprise (303 comments)

The guy in the book showed you can mitigate the effect by measuring the delays and making sure your order hits all the exchanges it's going to at the same time. Cost is a few reels of fibre (or maybe, if you were being fancy, some kind of controllable TCP delay insertion hardware). These fund managers make quite a bit of cash: I'd hope they'd try to understand the game they're playing, instead of hoping that things work the way they've assumed they do and complaining when they're wrong.

SEC Chair On HFT: 'The Markets Are Not Rigged'

squizzar Re:Not a surprise (303 comments)

You have multiple separate exchanges. It's not about routing, it's about delays to _separate_ venues. By watching what happens on one you make plays on the other. An article I read somewhere (I can't remember where, so please forgive woolly statement) had the HFT traders making a profit on just over 50% of the trades, they just make a _lot_ of trades is all.

Oklahoma Botched an Execution With Untested Lethal Injection Drugs

squizzar Re:What's the problem? (1198 comments)

Hypothetical: A person is is of the opinion that someone must die. Perhaps this someone has committed an act so heinous that the person in question feels they should no longer be allowed to live. Why should that person not kill them? Is killing someone so abhorrent worse than allowing them to live?

SEC Chair On HFT: 'The Markets Are Not Rigged'

squizzar Re:Fucking Casuals. (303 comments)

But they're those long term investors everyone wants in the market right? They're expecting to make more than those few pennies on the stocks aren't they?

This fantasy long term investor looks at things they could invest in, determines the potential return and risk of losses and picks stocks to invest in. So when placing the orders to buy these investments they set a price at which they thing it's worth buying - e.g. where their calculated risk/return ratio favours that investment over something else. If someone winds the price up, exceeding the limit, then don't buy it, buy the other thing.

If you're not going to adapt to the market that you're in - e.g. make use of the information provided - like the fact that there are HFT players out there - you're pretty much asking to lose money.

SEC Chair On HFT: 'The Markets Are Not Rigged'

squizzar Re:Not a surprise (303 comments)

Nope. The 'scam' in the flash boys (from the interviews - as per usual Slashdot expectations I haven't read the book) is that someone places a very large stock order for X at the current ask price that is routed to multiple markets. Let's call them A, B and C. From your trader the delays to those markets are 10ms, 100ms and 200ms respectively (which are ridiculously high numbers for this game). Your HFT trader has collocated servers at markets A,B,C, and minimal-latency links between their servers. So when the order arrives on market A and fills, they think 'Hmm, someone is looking for a shedload of X. They then place instructions to buy on the other markets, followed by orders to sell at a slightly increased price. They have 90ms (- the time for exchange A to match, fill, post market data etc., and the time for orders to be placed on other exchanges). It's like some slow moving person walking from stall to stall in a (physical) market buying all the oranges, and announcing loudly that they are doing so. Is it illegal to run to the next stalls, buying all the oranges and then offering them back to the slow moving guy?

All the information is public. The market data feeds are available to anyone. You pay for more up to date market data (which includes details of fills, not orders placed) - you don't pay for the 20-minute delayed stuff on google/yahoo, but you do if you want it faster. You pay for collocation. You pay for those low-latency connections. You used to pay for a trading desk on the stock exchange floor, guys in coloured blazers who could calculate and make decisions faster. The system has never been 'fair', but HFT doesn't necessarily make it worse.

Is the Porsche Carrera GT Too Dangerous?

squizzar Re:When you have a bad driver ... (961 comments)

If you are a super-duper-uber driver. Otherwise it's better at keeping the wheels turning at just below the point of locking up, which is where the maximum traction is. Hence why they used to teach cadence braking. Once you've locked the wheels the coefficient of friction is lower - and therefore braking distance longer - than when the wheels are just about to lock up. The big advantage is that with ABS every driver can mash pedal and stop in very nearly the same optimal distance as the 'best' drivers, and still be able to steer as well.

Chinese woman arrested for faking fingerprints

squizzar squizzar writes  |  more than 4 years ago

squizzar (1031726) writes "A 27 year old Chinese woman was discovered to have had her fingerprints surgically swapped between hands in order to fool Japanese immigration. FTA: "It is Japan's first case of alleged biometric fraud, but police believe the practice may be widespread."

"The apparent ability of illegal migration networks to break through hi-tech controls suggests that other countries who fingerprint visitors could be equally vulnerable — not least the United States, according to BBC Asia analyst Andre Vornic."

So it seems that biometrics are not the final answer to identity fraud, I wonder if anyone will stop pushing them because of this?"

IBM Claim patents promote open source

squizzar squizzar writes  |  more than 5 years ago

squizzar writes "I'm a bit confused by the reasoning in the Register Article here, apparently open source is "entirely based on relaxed or non-existent copyright restrictions", which is news to me. I thought that the whole mechanism by which open source code was protected and kept open was to use the strength of copyright laws.

I don't think they are being helped by IBM making statements such as: "without patent protection, the incentives to innovate in the field of software are significantly reduced. Patent protection has promoted the free sharing of source code on a patentee's terms — which has fueled the explosive growth of open source software development." As far as I understand it most open source software licenses specifically prohibit their use with code that has patented elements. Surely their argument better applies to an IP vendor, who is able to sell their code without losing control over it. Either way it seems both IBM and The Register are muddying the waters a bit here..."
