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.

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

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.

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.

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.

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.

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.

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.

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.

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?

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.

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.
