A small point of order here...
Hyenas are not canines. They're not even remotely related to canids, but are slightly closer to cats and mustelids than they are to dogs.

So, our initial Mars landers were all solar powered, and nothing happened. Now we've sent a plutonium thermal power source over to that planet, and things are happening now.
Cherenkov glow detectors setting off an ancient weapons system?
Let's just hope the system was inactive and didn't see where the lander originated from, eh?
This may be a silly thing to say, but I am struck by the coincidence between a sudden onset of DNS-based problems in the Great Firewall of China, and the emergence of a buffer overflow that can best be exploited via gethostbyname().
Might this problem not actually be anything to do with the GFoC admins or (in)competence thereof, but might it be related to some person or group inside China trying to break the firewall in some way, and succeeding in merely crippling its functionality in strange and annoying ways?
Actually, he is simply being brutally honest about himself, and is giving fair notice about who he is and what his personality type is. I also sympathise with his stance, because I would think he has tried the quiet, solftly-softly approach in the past, and found that it doesn't work.
If you have a product out in the world, then it can be examined, decompiled, analysed and scrutinised. Thousands of people are doing just this. If the product has a security hole, then this hole will be found, eventually. The OpenSSL flaw was likely known about for a very long time; any protocol where the code is a horrible mess is automatically suspect as messy code is much harder to debug than is simple, efficient, neatly-written code; messy code is often buggier than neat code.
The OpenSSL flaws were nasty, and disclosing them when discovered was the correct thing to do, and in a broader sense rapid disclosure is also the right thing to do as it forces a rapid fix. If you don't disclose flaws, they don't get fixed and while the swarms of brain-dead script kiddies don't get to hear of these flaws and thus there isn't a huge rush of witless knuckle-draggers trying to exploit them, this does not mean that they are not being quietly exploited for other, much more nefarious things.
Nuclear reactors are heat engines. If you're using small, local reactor units, then the cold end of the heat engine need not be a cooling system, but instead can be district heating of some sort.
Actually, you don't need to fret nearly so much about vehicle fuels. Whilst hydrogen is pretty useless as a vehicle fuel (poor energy density, hard to store etc) ammonia is much easier to store, and can be catalytically decomposed into hydrogen and nitrogen quite easily.
Ammonia is relatively easy to store, doesn't need cryogenic temperatures, and is easily synthesised using the Haber Process. It contains no carbon, and if generated using nuclear power, is as near to carbon neutral as anything is likely to get. Finally, all this can be done with existing technology, no near-future magic required.
The basic problem with a lot of historical temperature records is not the recording instrument accuracy, but the renormalisation of the records. As an example, take the weather thermometer at what is now Heathrow Airport.
The records there began in 1930 or thereabouts, when it was a grass strip in open countryside. It is now situated in the middle of a huge expanse of concrete, in the Greater London heat island. To get an accurate record of temperatures, you clearly need a fiddle-factor to take the temperatures of each time and transpose them back to what they would be if the site was a grassy field in the middle of nowhere.
It is therefore dead easy to slip in a little nudge so the renormalised figures go the "right" way by playing with the renormalisation formula.
This is the fault with almost all long-term man-made temperature records, and quite a few supposedly accurate natural ones.
The basic problem here is that it is obscenely easy for the government to enact new laws, and rather difficult to obsolete out old, or unused ones. As an earlier comment wisely pointed out, after a couple of thousand years of civilisation in Britain, you'd think we would have the legal structure we need pretty well sussed.
Actually, we do have a fairly well sussed corpus of laws. Most of the law is Common Law (as in what judges have decided in the past) and Contract Law, as in what is and is not fair to agree to, and which rights cannot be signed away. Most of how to handle criminals is also fairly well sussed, which is why laws like RIPA are so damaging; they throw a spanner in the known-working legal structures that already exist and also serve to highlight the fact that our politicians do not understand cryptography, and do not understand what "This is effectively impossible" means.
Thus, we are effectively letting deranged monkeys with sledgehammers loose in a watch factory if we let politicians prat about with fundamental legal principles like this.
This happened in Australia with internet gambling. The government there made it illegal, so the gaming sites simply migrated offshore to south-east Asia (in the case of the smart ones, using virtual hosting, this took mere millisecnds of downtime).
When the sites went, the tax money went as well, but aussies carried on gambling on the same sites just like before. Apparently nobody had told that government what was about to happen, so it all came as rather a shock to them.
Since not very much UK porn is actually hosted in the UK, and most of the rest is now hosted on https sites, I dare say the Government won't actually make much difference to anyone with this legalistic masturbation. Not that enacting unenforcible and frankly idiotic law seems to bother governments any more; it is now illegal, for instance, to detonate nuclear weapons in the UK.
Many, many years ago I was doing a PhD on the sex pheromones of some plant parasitic nematodes. The easiest way to tell if a male nematode thinks is chemical is sexy is to make a very thin layer of plain agar gel on a petri dish, put some of the chemical in the middle, wait a bit for a chemical gradient to form and then see if the male nematode moves towards it.
Now, there are several problems here. You have to know how long to wait for the pheromone chemical to form a gradient, and you also want to know how long it takes for the gradient to completely smooth out so that all it does is makes the nematode move about a bit faster, but completely aimlessly. The way to resolve this is by filming the responses of these nematodes.
This isn't easy. You're talking about a one millimeter long animal, which is almost transparent, moving in the film of water on a thin layer of gel, which you also do not want to dry out at all during filming. So, you build a box and put the petri dish on a small platform (with a dark background) and surround it with water, put a thin glass sheet over this (waterproofed with anti-mist spray or it'll mist up) and illuminate from the side with a cooled light source.
I did all this, and am proud to say that I solved the problem of how to set up a working sex pheromone test system. I also filmed the world's most boring sex-related videos in the history of the world which didn't actually feature any sex at all, but which had to be watched on fast-forward to see any movement at all.
You will be glad to know that these are now lost to posterity.
As things stand, parking fines and soon some other minor traffic fines will go straight to local councils when someone is fined. I would argue that this is putting temptation in the way of organisations which have already demonstrated that they will exploit such situations. So, remit all fines directly to central government, and let us see how local councils manage then.
In theory, as the parking restrictions were revenue-neutral this ought to have no effect.
In practice, this will force councils to cease relying on fines as revenue, and to find new ways to extract money from people. Motorists would still make a fine target; simply build a number of very big multi-storey car parks in and around city centres, and hey presto the cash cow can still be milked fairly easily, and at the same time people have an opportunity to go shopping back in city centres.
Yes, I agree. Then there's the fact that the Nexus 6 is coming out, and though it costs a lot more, you do get a much better product for the money. Waterproofing, for a start, and then there's the fact that Google will not permit anything to sully their good name.
OnePlus One, on the other hand, have kept on with the invite nonsense entirely too long. A little chase to try get an invite, yes, OK. Pratting me about for weeks with seemingly no chance of getting a phone; sod the lot of 'em!
Then there's the fact that they are using the known-vulnerable CyanogenMod image on the phone. We know there is one vulnerability on there, oh and this is a Chinese-made phone with a Chinese-modified OS on it as well. Feeling scared yet? The thing almost certainly has some sort of spyware on it, even if this is not activated by default or even at all. To add to the risk, the units are too cheap.
If you want to use nuclear propulsion of a spacecraft, all you do is re-activate the Orion Project. That used the most mass-efficient nuclear propulsion system yet developed: fusion bombs. The vehicle consisted of little but a huge and very well damped blash shield, a store of nuclear bombs, and (as far away from the blasts as possible) a shielded crew compartment.
Journey time from Earth to Mars with such a vehicle is weeks or months, depending on distance and acceleration.
To be honest we really do need a damn good clear-out of most of this cruft. An automatic sunset clause would probably do the trick nicely. So, if a law has languished unused for more than one calendar year, then it automatically gets repealed, unless a free majority vote of Parliament rescues it for another year.
That would either make Parliament run round like a headless chicken continually voting to rescue unused and unloved laws (which would preclude their enacting any more), or it would rapidly reduce the number of laws on the statute books to a workable minimum.
Added to this, there needs to be a stringent limit on the amount of secondary legislation permitted. This is things such as those regulations permitted by such acts as the European Communities Act, an enabler which permits laws to be brought into force without going through Parliament. As this is bypassing the regulatory chambers we have, it is introducing an awful lot of complete gibberish onto the statute books unseen and unread by Parliament.
On a regular commute of about 40 miles motorway, 20 miles of city driving per day in a 2 litre Avensis diesel, I get about 48 mpg. My normal motorway driving technique is to get the vehicle to 70 and stick on the cruise control at 70, then endeavour to maintain this speed. I do NOT hang about, and yet still get quite passable fuel milage. Of course, slipstreaming a big truck all the way to work will return an mpg of around 60 mpg (which I have done in real life; I am not making this up) but it is boring and time-consuming.
The numbers of drivers with poor vision are, in my experience, dwarfed by the numbers of drivers who are just plain stupid. A dearth of police patrol cars (especially unmarked ones) to remove such morons from the roads is also a contributary factor here; in times past bad driving habits such as aggressive tailgating at speed would have been spotted and punished; these days the idiots simply get away with it.
That reminds me of a not-very-subtle but still quite funny troll I once saw on the Usenet group rec.pyrotecnics. To understand this, you must realise that pyrotecnicians make pretty lights by burning chemicals, and think that just making something go bang is prostituting their art.
Thus a fellow who styled himself "Stumpy", asking if someone would be good enough to send him a bomb recipe in Braille, and preferably a not-very-dangerous one that wouldn't go off prematurely like his last effort had, caused ructions. It would appear that Americans are also a little more literal-minded than are Brits, hence there was a distinct Atlantic split to the responses to this chap. Truly a noble trolling effort, done by catering to the prejudices of the group and not insulting anyone along the way; that's how you troll correctly.
Usenet used to be quite good for that sort of thing. It occasionally descended into farce, too, when a group's resident flamer messed up his comment threading and gave a hearty roasting to a previous poster which turned out to be himself, then got all embarrassed when said mistake was pointed out.
Nah, I'd trot out a variant of BR's favourite excuse, and ascribe it to the wrong sort of vodka.
The real problem here is actually oil. Oil is difficult to extract and process, so hardly anybody can just set up an oil well in their back garden; in the Middle East what happens is that whoever is in charge ends up with this magic money tree which they alone control, and nobody else has anything much.
The ruling system in these states thus tends to end up something like a Mafia family, and if you don't subscribe to the peculiarly narrow brand of lunacy of the rulers, you don't get much of anything. Politics in these countries thus ends up at a dictatorship, and in the interests of a quiet life the dictators ruthlessly kill off dissenters.
Us Westerners marching in and topping the dictators merely opens the field for all manner of would-be dictators to take the field and try to substitute in a different brand of lunacy instead. There seems to be no end of different flavours of bloody stupid to choose from over there, so perhaps the best option would be to sit back and let them slug it out until the most violent ones have decimated each other. It also appears like most of these different factions hate the sight of each other and only ever unite in the face of a much bigger threat, i.e. the USA.
So, best to sit this one out. If our politicians fancy being useful for a change, then a very useful ploy that would benefit everyone including themselves would be a spot of intelligent economic warfare. Oil is useful portable energy, because it is so easy to use. Investing in cheap nuclear power would rapidly make electricity a lot cheaper, and investing in research into battery and supercapacitor technologies would make these work better as well.
If we suddenly can fuel our cars on cheap electricity stored in very fast-charging batteries, then the utility of oil suddenly will decline, and the price (and thus the profitability) of it also drops. Less money going into the oil states ought to calm them all down a fair bit.
As an example of how bloody crap the Soviet system was, there were several instances where Stalin was forced as the guy at the top of that society to step into disputes and simply dictate answers as simple as "move factory machine A into building B, then import a second unit".
The basic reason was that the system could deadlock far too easily, and did.
This is a point well made, and one which politicians would do well to remember. Economic growth is driven primarily by small businesses forming and becoming slightly larger small businesses; big corporations rarely grow other than by mergers once they hit a certain size.
Because of this, a country's tax and regulatory system must not act in such a way that it inhibits small businesses forming and thriving. In this matter Britain is something of a flop; such insanities as tax on account (i.e. getting businesses to pay what HMRC thinks they will owe before they actually produce the runover to owe the tax) are responsible for killing many a small business at the end of its first year, and, I dare say, forcing many owners into a phoenix-like death and resurrection of businesses annually.
Similarly the EU's demand that any company using any chemical must each demonstrate its safety and the safety of the final product is similarly a small business killer. Repeatedly demonstrating that dihydrogen monoxide is safe isn't in anyone's interest, save for big manufacturers who can absorb the cost and like this bar to new competition forming.
Manchester University Computer Science department has known this for years. They specifically go out of their way to present their students with deliberately different computer interfaces, including making all Linux kit start up in runlevel 3, in order to ram home the message that the fancy front end is NOT the actual computer (and there's nothing like forcing students onto a nineties-vintage window manager written in-house, where the most useful application is a terminal, to really force students to start thinking).
Surveys like this merely test how good the user is at interacting with the shiny top layer, and that is all.
A feature of some torrent trackers is that they include not only the actual people sharing a file, but also a random selection of pseudorandomly chosen IPs as well. As all these random IPs ever see is torrent clients politely asking if they'd like to share, then ignoring them when nothing happens, the actual IPs thus used don't know what's happening.
If they do get warnings sent, then we can merely assume that this is down to reading info off torrent sites. The probable backlash from this ought to be educational.
Plot in the Star Wars series is a bit like the wild giant panda; everyone's heard of it, people claim to have seen one, but it is always a friend of a friend.
The upcoming movie will therefore have an extended spacecraft battle to sell the space flightsim game, several hand to hand lightsabre duels to sell the FPS fighting game, several big battle scenes to sell the associated MMORPG and one or two planet-side fast moving scenes to sell the racing game.
Several different alien species will have walk-on roles; the bigger the role the closer the alien will conform to the "fluffy, large-head, large cute eyes" trope to sell plush toys. A suitably craggy hero will be present to keep the mothers of the expected hordes of pre-teen kids awake; said hero will be complemented by a suitably pneumatic female lead role to keep the young-teenage males awake and *ahem* interested.
A large variety of weapons systems, both robotic and stormtrooper-wielded will be seen. All will share the characteristic of being so inaccurate that the wielder has next to no chance of hitting a large barn with one, even if standing inside with the doors closed (several stormtroopers will perpetuate the "really crap aim" standing joke). No truly effective large-scale weapons or tactics will be used, similarly hacking, infowar and similar technologies will be entirely absent.
Once all the above has been slotted into the film, approximately four minutes and thirtyseven seconds will be left for a plot. The rolling titles at the start and finish will cut this by half.
Take the 9/11 terrorists. They didn't ever send any emails, merely edited a draft email and used a shared email account as a remote-accessible dead letter drop. This metadata retention law would not have caught them.
Consider the London bombers. They didn't send each other emails either; everything was face to face, word of mouth. Again, no luck.
Consider every would-be internet jihadi. They send shedloads of emails, rant away like nutters on Facebook, and generally talk a bloody good terrorist campaign, yet are about as likely to kick off World War 3 as the England team are to beat, well, pretty much any other football team in the universe.
NSA-style data trawls catch loudmouthed plonkers (of which there is no shortage), but miss actual terrorists (who are fortunately vanishingly rare). This entire law is basically security theatre at its shoddiest, most ineffectual depths.
PIR-controlled sprinklers are already available on certain online retailers (no plugs here), and PIR noise-makers are also fairly readily available. If there's nothing really attracting a cat into your garden, a PIR-controlled ultrasonic noisemaker is going to deter most cats. One thing, though; if the device is in a public place, beware of small boys stealing the devices. Small boys seem to have next to no inhibitions in this regard, especially if they have not had prior experience of CCTV and burglar paint.
Alternatives to the electronics are garlic essence, Jeyes Fluid and sticky materials of various sorts.
You know, I think I see a potential market here; waxwork dummy security men to put outside your doorway, as a mark of status. Hell, were I living in proximity to Tony, I'd hire a couple of Star Wars stormtroopers to stand in front of my door, just to upstage him!
Modern encryption renders this argument completely invalid.
Say we have a widely-dispersed cell of terrorists. They want to talk, but they would prefer not to let GCHQ in on their plans. So, each member publishes a public key, keeping their private keys secret. Whenever each fancies a chat, he creates a document, encrypts it with the public key and publishes it on Usenet in a binaries group. He doesn't send it to anyone specifically, only the entire world including GCHQ, but only the intended recipient will be able to decrypt it.
Our hypothetical terrorists will be a chatty bunch of criminals, limiting themselves to one document out per day, but burbling on about this and that even if they've got nothing of great import to say. This stops GCHQ spotting an upsurge in comms traffic and inferring anything from it. Nor would GCHQ be able to infer anything from who talks to whom, as they do not see any addressing info at all, merely encrypted gobbledegook that makes sense only to the recipient.
This sort of trick is probably already happening even as I write these words. It is a simple way of avoiding leaking metadata; leak the comms to the whole damn world including the spooks (who can already snoop it) but rely on strong encryption to limit who actually understands it. As far as is known, strong encryption does not have any holes in it, so absent quantum supercomputers, encryption is secure.
What you want to do is build on the Brott series of grasscutters. These were small paddock mowers, and the best way to describe one is to think of a bastard cross between a Harley Davidson and a silage harvester, as built by a slightly insane bucolic Hells Angel.
It was a ride-on flail mower, which collected its grass clippings as it went. Standard practice using one was to put it in bottom gear, and run the engine at maximum revs; this produced a deep drone from the flail mower combined with a howl from the engine. These mowers would cut pretty much anything, from grass to wood to molehills and so on. Cats and dogs getting in the way was not a problem; anything with a brain headed for the horizon if it heard one coming; anything without a brain got pulverised.
This would be an ideal platform to build into a mower-bot.
Most of the time, an electric-only vehicle will do just fine as long as there are charging facilities at both ends of the journey. When there aren't or when the driver is going further, then the electric-only vehicles will not work.
If you are dead-set on building a vehicle that is carbon-neutral etc etc, then a mostly electric vehicle with a fuel motor to extend or recharge the electric batteries is the only option. Apart from carbon-based fuels, the only sane alternative would be ammonia as this can be liquified and kept liquid at reasonable temperatures and pressures, isn't wildly explosive or dangerous and isn't stupidly energy-poor.
So has anybody who has looked at the webcache of even a small ISP. Honestly, you really, seriously do not want to look at the jpegs in an ISP webcache; they've got nothing on goatse.cx at all.
The standard reply I give when asked what PC/Laptop to buy is "Anything made by Apple"; this normally elicits protestations about the heinous cost of the kit. When I merely say "Quality costs", they normally shut up and go away. Seriously persistent people get told all about the marvellous qualities of secondhand Sun kit; they rarely bother me twice.
I've had the experience of some stupid bastard trying this on me, whilst I was driving a car. In my case, it was a low-powered red laser, the moron was a good few hundred yards away and had really crap aim and was to one side of me, so he only got one eye very briefly.
However, it is blindingly bright. You literally cannot see a bloody thing except the laser, and had it not been a nice straight section of the A56 near Accrington on a quiet evening, the temptation would have been to jump on the brakes simply to slow down to a safe speed.
In an aircraft, with dark-adapted eyes, with a green laser (a colour to which human eyes are much more sensitive) probably of illegally-high power, the effect must be devastating.
If you actually visit that bit of the google maps and look back at the scene then as the google car leaves, you can see the "murder victim" first move to stand up, then in the next shot the corpse is standing, striding away back to the workshop.
Funny the police couldn't do that as well, isn't it?
This is basically how these cars will take over. Most of the time, people just want to get from home to work, or the supermarket, or whatever with the minimum of hassle and as the bulk of commuting is the hassle of interacting with hundreds of other barely-functioning monkeys in metal boxes, automation of this will be very welcome indeed.
Motorways will be the first bits to be automated. Imagine a set-up where you engage the autodrive as you get close to a motorway, with a destination programmed into the machine. As you get onto the motorway the robot negotiates with the motorway sub-systems and joins you up with a line of cars all closely-tailgating behind a big lorry (whose driver is likely half-asleep, as his vehicle is also running on autopilot). This is called platooning, and cuts the fuel use of the vehicles dramatically.
You get from home to work a bit slower than you might otherwise do, being restricted to the 56 MPH of the big truck, but as a bonus you've only used half as much energy and most of that came out of the batteries of the plug-in hybrid you now have.
As you come off the motorway, the car hands back most of the control to you, but also talks to the city computer net and works out a path through the rush-hour traffic for you, avoiding hold-ups as it does so. It also suggests an optimum speed, so you hit traffic lights only at green.
Propane is as far as you really need to go on this sort of polymerisation chain. As soon as you get to propane, you have an alkane that can be liquified trivially and which does not need insanely high pressure or low temperature to keep it contained, plus the engines burning it usually run efficiently without generating much pollution.
Probably the best way to use propane is a hybrid engine design, using solid oxide fuel cells as the primary burner, and running the exhaust from the cells through a Stirling Cycle engine to recover some energy from the waste heat. You then have two good sources of electricity, plus a heat exhaust which can be used to feed into the vehicle's heating system by way of a heat exchanger.
A company in Illinois recently developed the lead-acid battery a little further, by replacing much of the lead in it with graphite. This makes their lead-acid cells lighter, more durable and less fragile than normal lead-acid cells. These sorts of batteries could be used as the temporary storage section of this hybrid electric vehicle.
As things are going now, Google and quite a few others including the open streetmap project are also sorting out their own versions of the PAF. The open streetmap project's one is completely free, too, and Google can be persuaded to let you look at data fairly cheaply. The result here is that any big outfit that wants their own mostly-accurate free version of the PAF can get it now, and as these free versions are being continually updated and corrected, they're only going to get better over time.
As the free versions of the PAF get better, the advantage gained by paying for the proper PAF diminishes, so the monetary value of the proper PAF also diminishes. The decision to sell it off now was probably the right one, as this was probably the last moment in which anyone would bother to pay good money as opposed to rely on the free versions.
Get the police involved, then agree to pay the money. Sort out some means of paying that is trivially traceable, and set Plod off to sniff down the blackmailers; pretty soon, exit crminial numpties stage left.
Yes, it would appear that indeed they were. Bitcoins are cryptographically secure, but only if you are holding them. If some other entity is holding them on your behalf then you'd better hope that said organisation isn't run by stunned muppets who're still amazed that this moneymaker has landed in their laps.
"Mt.GOX" actually stands for "Magic: The Gathering Online Exchange". The site started out as a PHP page bodged together by some spotty herbert who wanted to try to make a percentage off trading playing cards in some poxy role-playing game. The key thing to remember is this: the site was PHP, written by an amateur and never needed to be audited in the early days as the money flows were peanuts; this was a site so insignificant that not even the tax men took much interest.
When said operator switched to bitcoins, once again the cash flows were peanuts because bitcoins were worth next to nothing. The site got away with abysmal security and a complete lack of auditing because it was too small a minnow for anyone to be bothered with, and bitcoins were not considered to be money as such.
Just because nobody has broken into a site does not mean that it is secure. It might be completely insecure, but even script kiddies do have standards. Very low ones, it must be said, but pulling a heist for a few hundred worthless coins is not the stuff that online crime legends are made of. As soon as bitcoins came to be worth something, then the sharks moved in and it would appear that the MtGox operators were so dumb that they never spotted that they were being swindled blind.
The lesson here is simple: don't trust idiots with money, or shiny money-like stuff.
Lead pollution is the cause of quite a lot of crime, and we have the USA to thank for proving this. Lead in petrol (tetra ethyl lead as a fuel enhancer) was phased out by different states of the USA at different times, and at differing rates. Interestingly the rate of reduction of crime in the young male population fairly closely mirrors the decrease in exposure to lead very early in life.
It seems that men are much more sensitive to pollution than are women (or merely lack brain redundancy to cope with minor brain damage) and are also much, much more likely to turn criminal as a result of minor damage caused by pollution. Lead is the chief cause here, as it is a neurotoxin, and the damage seems to happen in the first year or so of life.
Now that we've phased out lead and are getting much, much more savvy about other environmental pollutants such as phthalates and the like, we can expect crime to reduce further. Every improvement has about a fifteen year lag between the improvement and the crime reduction, hence this correlation has hitherto been missed, but it is there and is measurable.
Nothing identifiable needs to leave the GP, but this assumes that whoever is processing the data has basic competence and at least marginal clue. Past experience with the civil service disproves this assumption. Examples here include:
Encrypting data, putting it on CDs and writing the decryption password on the CDs
Dumping out entire databases including sensitive identifying data onto USB sticks, and losing them.
Losing sensitive data about criminal informants where this may be found by those they are informing on.
Put simply, the government and civil service are too incompetent even to run a bath best out of three. They suffer from the inverse Midas effect. A recent example is kowtowing to the EU so much that dredging of flood-prone rivers was ceased, making it a matter of time before catastrophic flooding occurred and this stupidity was discovered and the mistake traced back to the miscreants. These people are too stupid even to guard their own backs.
Don't trust idiots with sensitive data!
To be honest, actually encouraging as much feature creep as possible is entirely the right thing to do, since this will force Joe Public to learn all about how to get around said filters and how the government are a bunch of techno-illiterate numpties. So, bring on the Orwellian censorship, bring on the mumsnet-inspired wuckfittery, and bring on the "for the childrun!!1!" smothering censorship.
The population needs a lesson on why getting what you asked for is a bad thing.
Far, far back in the mists of time, when I was a PhD student working at a very respectable research establishment in Hertfordshire (hint: used to belong to John Lawes), I suffered an unfortunate accident involving a door that ought to have been cordoned off, a lack of lighting and an open manhole. To add insult to injury, falsified security records got me a bollocking off my head of department afterwards.
Subsequently I obtained a pocket-sized torch and ever since have made a strict habit of always carrying some form of small light source with me wherever I go. Fenix make some very nice ones these days, tiny but durable to survive in a pocket together with one's small change. Such devices are also useful for drawing attention when walking down unlit roads by night.
Actually, rather than stick sensors all over the place in lightbulbs and so on, there is a case for centralising the sensors into one unit, and simply moving that unit around as needed. So, you start off with the basic kit of a house computer & server, plus wifi, plus some sort of robotic pet. All the sensors you need, you stick into what will probably end up looking like a rotund robotic kitten.
That way you have a platform to move the sensors around the place, combined with something that people actually quite like to interact with, and which can double up as a night-time fire sensor and watch-dog of sorts (with most of the smart processing being done over wifi by the base computer as the kitten sits on its wireless charge-pad acting more or less like a webcam).
We do not need to go "build our own" flying car; this has already been done. Gyrocopters are the closest thing you're ever going to see to a flying car, without huge expense, and they are a niche toy at best. This is even with the facts that they fly in autorotation all the time making them easier to control than a helicopter and much harder to stall than a conventional aircraft, have a maintainence footprint much lower than an equivalent helicopter, and have short take-off and landing capability.
In short, a relatively unskilled person can be trained to become a gyrocopter pilot, and gyrocopters can be flown relatively cheaply and easily. Yet, this doesn't happen. Why not? The simple answer is, we do not need flying cars.
Google self-driving cars are a much better idea.
The anti-sports rant is, in my opinion, entirely justified. Games teachers have a well-deserved reputation for stupidity, and it is my experience that this took the form of never troubling to explain the rules of any game "taught" to us pupils. Rugby especially was never taught or explained, and thus in any given rugby game at school consisted largely of the few people who actually knew what was happening running around, lackadaisically pursued by the majority who hadn't a clue, and would much rather opt out of the entire mess.
Not as easy as you might imagine. The one pictured is not a European species; common house cockroaches do not grow that big. To obtain one that big you'd have to buy it from a specialist supplier (who might well balk at selling animals for what is at best unskilled experimentation).
Then you have the fact that the procedure is going to be a tricky one to perform. You're not going to get this right first time on the first roach you get, this is going to need practice, and practice means lots of live victims which won't be alive after you're done. With the average child, factor in boredom too as the procedure is going to be extremely fiddly to perform. This won't mean just a few roaches killed, but a couple of dozen perhaps.
So, after you've learned how to freeze-anaesthetise the insects properly (killing a few, drowning others), you have to learn how long to freeze them for, and how hard you may grip a feebly struggling and quite slippery insect to sandpaper its head. Once you've had a bit of practice, and wiped cockroach guts off your hands a few times, you'll be ready for a spot of antenna-snipping.
This won't be easy either, nor will lining up the hole in the antenna with the fine wire. This is really a job for a binocular microscope, but you're not going to have either the excellent Wild microscope I had in one place I worked, nor even the crappier East German Zeiss I used later elsewhere. No, you're stuck with a single magnifying glass. Best of luck, you'll need it.
Inserting the ground into the thorax after this won't present much of a problem, and you'll overcome cross-talk with RF interference making the roach walk in random directions quite quickly, though not perhaps as quickly as the cockroach dies of dehydration (remember, this is a shop-bought tropical cockroach, and likely a leaf litter detrivore and not the dehydration-resistant pests we are familiar with).
At the end of this blood-bath (well, haemolymph-bath) of an experiment, you briefly have a remote control cockroach which will occupy a child for all of five minutes.
Was it worth it?
You do have to wonder why the NSA, with a multi-billion dollar budget and access to some of the best minds in the business, are not using two-factor logins of some description. Snowden would have fallen at the first hurdle were a random number fob or a fingerprint (or both) needed to get into machines; certainly an override system would have had to have been present also, but such an override would be very heavily audited indeed.
Perhaps there will be some openings in the NSA for people who know about basic security...?
Competition with the local ADSL is actually EXACTLY what you want. As soon as someone starts competing with Brutish Telecom then said company has to up its game or lose trade, and it usually isn't smart enough to realise that a local company is just that, local, and not a national threat.
To be honest here, what we're currently using encryption for is vermin control, and it really doesn't take all that much encryption to keep modern crooks out of, say, a banking system. Most of the time we don't need to keep the NSA out, because the average person bumbles along not doing very much of interest to a major spying agency at all. About the most that the average punter gets up to is a spot of marital infidelity or low-level larceny; annoying on a personal level but profoundly uninteresting to the NSA.
The mistake here is to imagine that shoddily-executed, vermin control encryption is going to keep the big boys' noses out of your data. It isn't; only the sheer banality and uninterestingness keeps them off your back. The only time to start worrying significantly is if or when the NSA starts routinely leaking the data it has sniffed out to other agencies or even commercial companies; as soon as it does this, it joins the ranks of internet vermin.
Once on the vermin list, I doubt the NSA would ever get off it, and once the world realises that shonky encryption won't do the job, geeks everywhere will start trying to up their game and lock the NSA out. The actual terrorists already do this; face to face meetings and lone-wolf attacks are almost impossible to spot online.
