Intel tests definition of insanity with (leaked) typoslab Skylake CPUs

The definition of insanity ...

... might well be making the same mistakes over and over again and expecting different results --- but nearly every form of success other than 'striking it lucky' comes from trying things again and again until they work - whether it's creating and marketing products, kung fu or musical performance.

Hold that upgrade: Critical bug in .NET 4.6 'breaks applications'

Classic Heisenbug?

"Attaching a debugger, says Craver, changes the behavior and usually hides the issue."

The only one I've every experienced directly in my professional career was in a mainframe screenscraper --- when logging was on, the submillisecond delay caused by writing the log entry was enough for the MF to respond, and to hide the fact that the procedure didn't wait for the response if it wasn't ready; with logging off the procedure just fell straight through and returned an empty response.

Re: Password managers

"Password managers don't have to be run 'in the cloud' - they can be standalone applications running on your computer, and which should therefore continue running long after the developers have gone." -- VinceH

Here's mine:

echo -n 'mymainpassword myusernameforthewebsite thewebsitename' | sha256sum - | xxd -r -p | base64 | tr 'a-m' '!--' | cut -c -20 | xclip

When my browser can't remember a password, I just run that script in a terminal, then middle key click the password input field to paste a twenty character password, with 6 bits of entropy per character. If you used the literal values in the case above it would be: 3"'MnsKA-&t74GD&,GxE

For stupid accounts that insist on alphanumeric only, replace the 'tr' command (with something like sed "s/[+/=]//g"). The script works with very little modification on windows too. I also have a version that does a non-echoing prompt for the main password, but I tend not to bother with that now unless I'm aware I may be overlooked (but it's also good if you don't want it to end up in your shell history):

read -s -p "Password:" PASSWORD && echo -n "$PASSWORD myusernameforthewebsite thewebsitename" | sha256sum - | xxd -r -p | base64 | cut -c -20 | xclip

BlaneBramble >>> Not if there is a substantial obstacle 10m West (wall, lake, large drop, etc.) of your destination."

Well, when I'm driving the car myself, I have an additional gadget that warns me of obstacles unknown to the satnav, aka Mk I Eyeball; self-driving cars have radar / lidar. But my original comment was just a poor attempt at humour, I knew that 'm' meant miles in this context.

Olaf's point, though - that someone could quietly reprogram your satnav, is quite an interesting one - especially combined with control over speed, doors etc (or a self driving car), it could certainly facilitate carjacking or abduction.

Re: @Mongo - Yet again poor design and great hacking reveals me as a muppet

"The real muppets are the ones whose poor programing practices allowed such things to happen in the first place!" -- Graham Marsden

I disagree, they are merely inexperienced graduates and/or other noobs. Or, quite often, they have already raised concerns only to have them airily dismissed. The real muppets are those who actually have the power to make decisions (which, in practice, always means budget controllers) on hiring, testing, and quality control.

Even a single, highly experienced and or qualified software/security engineer attached to one or more of these teams would make a difference in quality. The difference that 1st level management see is a 1% increase in their budget, so they demur. But even these managers are relatively blameless: they know that, whatever they say, those above them see only $ signs, and that if they are seen to increase their budget by 1% they are automatically regarded as failing, as no justification would be understood (to be honest, even given an audience) by higher management.

This status quo will continue until those at the top suffer financially or legally. They cannot be allowed to continue to micromanage budgets all the way down and then shrug their shoulders at the almost inevitable consequences.

Keep your stupid drones away from piloted aircraft, rages CAA

John H Woods
Silver badge

If flying drones near aircraft is really dangerous ...

... surely additional legislation is inappropriate, given that (a) existing legislation would appear to suffice and (b) there are, as we are constantly reminded, a non-zero number of people who would endanger aircraft on purpose.

Can't those people charged with ensuring our safety come up with some electronic counter measures and some electronics / software to trace operators?

I'm pretty sure there's going to be a market in anti-drone devices, as an anti-paparazzi measure for wealthy celebs, if nothing else. Wonder what you'd need for safe capture? Anyone fancy going into business?

Re: Credibility

"I believe PLOS One is an 'open' journal that allows you to publish anything so long as you pay the fee. So long credibility!" -- Banksey

"PLOS ONE takes the hard work out of publishing. There's no stress waiting to find out if your article meets subjective acceptance criteria. As long as your work reaches a high technical and ethical standard, PLOS ONE will publish it - and make it freely available to a global audience."

This is not quite "anything" it just relaxes the peer-review requirement, similar to arxiv.org. It's not that one should immediately discount anything that's written there, but that one should be sensitive to the context.

"I can believe this level of incompetence though. I am leaving my job working with 'med-tech' because the software standards I experienced made the rushed code for a mediocre game look like NASA code. The software profession tolerates a lot of idiots." -- GameCoder

The trouble is that software is not a "profession" -- it is a job. We don't need to regulate everyone, but probably those who develop safety critical systems, and possibly those who develop any internet facing systems, should be qualified and/or licensed to do so -- not so much to stop developers misrepresenting themselves, which is fairly rare, but to prevent corporations' simply choosing the 'lowest cost resources' for development, skimping on testing (i.e. avoiding any realistic or significant testing at all) and simply shrugging their shoulders when things go wrong.

Never mind more than a curiosity...

... if you could create a nice small black hole in a nice stable container, you could chuck mass in it and harvest energy given off as Hawking radiation. It would be the ultimate waste processing facility - the waste is gone for ever and the energy extracted from so doing, if you feed it just fast enough to stop it evaporating, approaches the theoretical maximum.

Re: How would we know?

This is testable - in a solipsist manner: all you have to do is commit suicide - or not - based on a quantum event (e.g. make yourself a Schrödinger's cat). At a 50% chance of not making it out of the box, by the time you've done it 5 times, it's starting to look like it's true. By the time you've survived it 10 times, it's probably true. By the time you've done it 30 times, the chances that it's false (providing your set up is correct) is about one in a billion.

What neural networks think ...

Check out this Google Research Blog where they get some insight into what ANNs (artificial neural networks or "AI") have actually learned by feeding them random noise or images of clouds and (simplifying here) "asking them" to identify buildings or animals.

The identification is, without the G-word, one of dark skinned higher apes and, on a naive level, this is not really a failure: the gorillas, the chimpanzees and the bonobos are our closest living relatives. And by close, I mean really close, on a deep genetic level. The connotations of the word are terrible, but that is because of centuries of human racism, not because ANNs (or Google) are "racist". The reason white people aren't identified as such is because we are the mutants who lost our ability to produce large amounts of melanin, resulting in a very obvious visual difference: one which, to ANNs, can appear much more significant than it really is. In fact, it just means we can tolerate cooler climes somewhat better and intense sunlight a hell of a lot worse. They'll have pulled the ANN now, but I'll bet that a 'negative' of a group of white people would also have produced the same result.

Where other visual indicators are more significant, the ANN picks that. Note that, despite the subject not being white, the last picture in the tweet is correctly identified as being one of a graduation.

Ecobee3: If you're crazy enough to want a smart thermostat – but not too crazy – this is for you

John H Woods
Silver badge

Re: Does it really save that much?

"Your heating bill is driven by the heat loss from your house. The rate of loss is set by the standards of insulation, but if you see those as set, then your heat losses are proportional to the delta between inside and outside temperature, multiplied by how long the heating is maintaining that difference." -- Ledswinger

Sorry Ledswinger, I do understand the physics, but I'm still not convinced. Say at 5℃ outside, your house, at 20℃, is 15 K hotter. You drop the thermostat to 15℃ when you are out. Eventually, your house will get to 15℃ and your heat loss rate will be two thirds of what it would have been. But, until it gets to that temperature the reduction of your heat loss is less than a third. And when the heating goes back on, it has to work harder to raise the temperature of the house.

So if your temperature drops to 15 quite quickly, your have more serious problems that your thermostatic control. And if it drops quite slowly, your house is so well insulated that you may as well keep your heating on. You probably don't want to drop your temp by much more than 5K, not just because your heating has to work harder, but because you don't really want to temperature cycle your house and its contents by much more than this on a regular basis.

So, a themostat thats 5K lower when you are out can save you money, but maybe not as much as it seems. But these things have to be even better than that - because their opportunity to save you money is only when you are out and you didn't expect to be. And the most common scenario I see quoted for this "late home from the office" is only going to be a few hours of cooling. Finally, there is only a very brief period in family life when you are all out, or all in at the same time, so unless your the kind of office worker who thinks the spouse and kids should shiver along with you when you're stuck in the data centre, I just don't think the maths adds up for most situations.

Does it really save that much?

Going out on a limb here (having no central heating at all, I don't know) but does it really make much difference turning the temperature down when you're out? Surely that can only be the case if you really need to buy some insulation? Or perhaps even shut the windows.

My guess is that these people are at the bottom of various pyramids, or at any rate, simply selling anything they think they can sell which makes them a reasonable margin - it's just two steps up from begging (the next step is washing windscreens at traffic lights) and I think you are correct that the principle reason for the weird item choice is poverty.
