Rip up your AMD obits: Gaming, VR, embedded chips to lift biz out of the red by 2016, allegedly

Re: AMD APUs with HSA look ground breaking

I agree. Price performance is where the AMDs still hold their own against Intel. My kids have a cheapo gaming rig that is able to deliver perfectly acceptable HD frame rates on modern games on most settings, using an overclocked (and boy can they overclock) A10. Even before we added a proper graphics card (need a way to get started without killing the 300 quid budget) we were getting fairly respectable performance just using the A10s own GPU. With a moderately good AMD card added, performance is pretty good, and that and an SSD still didn't take the total cost over 500.

Re: get the units right

"the battery is a 2.0 Ah not 2000 mAh" -- AC

You could call this battery a 7.200E+03 Coulomb (i.e. Amp second) battery, but as most people are interested in how long the battery lasts and what the phone's power consumption is, it is more appropriate, in this CONTEXT, to use the derived unit of Current x Time rather than Charge. Similarly, the scale, in this CONTEXT, suggests that we use mA rather than A (given the sorts of power consumptions that phones have) and h rather than s (given the sorts of durations that phone batteries last).

* Also, as an aside, 2.0Ah is not quite the same as 2000mAh: the former suggests (a hundred times) less precision (i.e 1950mAh to 2050mAh rather than 1999.5mAh to 2000.5mAh) although again an understanding of the CONTEXT would suggest to most people that the range of variability is unlikely to be as small as 1mAh

Re: why, why, why... what is the point?

You'd better read (a) the news and (b) some history books.

If you think your news browsing, video watching, Register-posting habits -- or even your musical tastes -- do not let The Powers That Be characterise you pretty fully, you need to think again. The Powers That Be, here in "The West", of course, are reasonably benign (to what degree is a matter of discussion) at the moment; but there is absolutely no reason to assume they will stay that way, wherever you place them on the malignity spectrum at the moment.

Re: Getting a good cup of coffee?

Phil Dude, I believe you are spot on. Charbucks over-roast their coffee on purpose to give it a distinctive strong taste that is mistaken for quality by people who don't know better.

I love Italian coffee --- Illy is fantastic when it is on special offer, Lavazza will do when it isn't. And I think Lavazza's Modo Mio pod machines are pretty good. But, although it's pretty hard to source in the UK, I also love Portuguese blends like Nicola.

Bialetti's are good, but I've never really enjoyed cafetiere coffee, as I find it hard to get a grind that is uniformly coarse enough to avoid the muddy bottom you get from the material too fine to be filtered by the mesh. But then I discovered the Aeropress ... great coffee from a cheap, robust, easily cleaned device with minimal environmental impact (and a bonus miniature arm workout if you put in enough grounds) -- what's not to like?

SHA-1 crypto hash retirement fraught with problems

John H Woods
Silver badge

@Boltar, Antonymous Coward

I was over-simplifying; however my comment was for the benefit of those who might be misled by the statement that "...hashing (one-way) function) ... from which it is impossible to recover the original information" and who might not realise, given the context, that that is true of all hashes, and not just of secure ones, and that the defining feature of secure hashes was actually collision resistance.

My statement that it is only really "secure" hashes where you can "recover" the input should be taken in that context, just an ironic fun point. Of course I understand that, in the absence of size restrictions, there must be an infinity of inputs that have any given SHA256 value. But the chances of the original input having the hash I quoted having been something other than 'password' are very small indeed. So although you cannot really "recover" the information from the digest, you have a lot better chance of guessing the input than you do for, say, a given CRC function. (Although obviously such guessing is severely limited --- the input would have to be present in a "rainbow" table of inputs for which you have already precomputed the hash).

"SHA-1 is a hashing (one-way) function) that converts information into a shortened "message digest", from which it is impossible to recover the original information."

This might suggest that inability to recover the original information is what makes a given hash function secure: it isn't. In fact, secure hash functions are actually the ones from which you might* be able to recover the original information!

A hash function is secure if it is (very) hard to create any different inputs with the same hash --- most particularly that it is very hard to manipulate the input in any manner whilst preserving the hash value.

* by using rainbow tables. e.g. if you say 5e88 4898 da28 0471 51d0 e56f 8dc6 2927 7360 3d0d 6aab bdd6 2a11 ef72 1d15 42d8, I know the original message is "password", but that doesn't mean that SHA256 is any less secure.

Spooky smartphones

Sometime in the last decade, enough idiots (including myself) had asked vague questions on the Internet and had them answered by kind knowledgeable people that internet search itself has become spookily good at vague queries. Having access to this knowledge in a dark country lane in the middle of the night is pretty weird when you stop to think about it.

The other night, walking the dogs, an image popped into my head, frustratingly without the words that should go with it (I'm getting old). My old mastermind of a dad being dead these past twenty years, I risked it: "OK Google. What's the name of the famous American painting of the old couple with the bloke holding the pitch fork?" Not only did the phone get the speech word perfect, but there was the answer: "American Gothic" by Grant Wood. When did it get that good?

"The Blacklist is truly dire television, even by TV standards"

No! It's great!

Does that count as a counter argument? If not, your position is hardly better supported: saying you don't like it because the acting, direction and writing is bad is pretty much the equivalent of the announcement that the train is late because it has been delayed. Dismissing something so popular and widely acclaimed (by both critics and the public) as if its lack of quality is immediately apparent to anyone with half a brain is the equivalent of publicly stating that you are smarter than everybody else. It might be true, but it's yet to be proven.

Re: I'm suggesting it.

"Even if you are pessimistic about long term effects, you cannot round up any realistic guess at the nuclear impact to a level where it even counts as a significant part of the tragedy." -- me

"That's a very simplistic viewpoint, basically that tragedy equals death and nothing else." -- 1980s_coder

I disagree. What it actually says is that NX << MY where

N is the number of people living in (unnecessary) fear, and I accept your point that it may be large

X is the tragedy of a person living in fear in some arbitrary unit

(What is the El Reg unit of tragedy? Perhaps a 'Verdi')

M is the number of people who actually died (~15,000 < M < ~20,000)

Y is the tragedy of a person dying

I'm not discounting the tragedy of hundreds of thousands of people living in fear, sucks for them, even if they are worried about basically nothing. But I am still saying it's insignificant compared to the tragedy of thousands of people dying.

"... it's ok not to build a wall higher than 10m (or whatever it was), to protect the emergency backup generators for the nuclear core coolant system." --- MIke 125

It's off topic, but I need to rant (again) ...

This annoys me a bit, the idea that nukes can only be considered safe in they are protected from everything. The Tohoku earthquake was a 9.0 magnitude affair epicentered less than 100km offshore, and had an energy of not far off 10 Teratons of TNT --- five hundred million Hiroshimas. Relatively ancient nuclear plant was hit by a massive earthquake and a huge tsunami.

The Tohoku earthquake caused at least 15,000 deaths, probably 20,000. The Fukushima nuclear "disaster" caused, erm, pretty much none. Even if you are pessimistic about long term effects, you cannot round up any realistic guess at the nuclear impact to a level where it even counts as a significant part of the tragedy.

Re: collect it?

UK mail order rights (e.g. returning non-faulty goods because you don't like them) cease to apply when you click and collect. If they mail it to your house, you have vastly more rights than if you take it from a shop, regardless of whether the payment was made online.

I have a slightly tailored approach: "Unauthorized access to this system is an offence under the Computer Misuse Act, 1990. The access code is 1234." But I think it's mainly academic - many autodiallers have 'grunt detection' - a bit of software that tries to determine, from aspiration etc., whether the voice on the other end is live or a recording. Anything that sounds dull and flat causes a hang-up. Try it: answer the phone as if you were recording a message!

This is negligence, pure and simple...

... there's some pretty cost effective software I have come across that automates the discovery of personal content on publicly accessible web and file servers, and raises alerts accordingly. I think you might even be able to do it with Google Alerts if you used your imagination.

Certainly the Goog, and other major search engines, could easily run a service which lets you know if it discovers things that look like bank account numbers, social security numbers, even addresses, on your site. You set up some exclusions, like the company's own address :-) obviously --- and as soon as you get a notification email, e.g. "The number of publicly accessible bank account numbers on your site has increased from 3 to 123,456, and the new instances are here: ..../path/to/cockup" then you can start doing something.

Graphic designs: Six speedy 17-inch gaming laptops

John H Woods
Silver badge

My son's Bargain Gaming Laptop ...

1) an old T420 from fleabay with a decent i7, 16GB RAM, 128TB SSD for OS and 1TB Hybrid SSHD for Content (£300 + £100)

2) a Village Instruments eGPU box with a PCI-E interface (£100)

3) a decent PCI video card for the above (£200)

4) (optional) external monitor (£200)

Not only does he get a cheap, tough laptop with decent battery life, but when plugged into the other stuff, back at the dorm, he gets framerates that challenge your average gaming laptop. Feeding the video back into the laptop, rather than an external screen, it's eminently playable (60fps on fairly high graphics settings for many games), but on an external monitor, the frame-rate for any given graphics setting is approximately double (I presume the constraint is the speed of the PCI-E).

Not as portable as any of these covetable boxes, but pretty good going for an impoverished uni student who is away from his home gaming rig for whole WEEKS at a time :-)

Pattern unlock (and to some extent PIN) not that secure --- many screens show some residue of the patters. Face unlock is fun gimmick (although I think I need to know why my eldest son can unlock my phone and not my youngest!) but not good enough to secure your phone.

Redirect calls from certain numbers (boss? mistress?) if you are at home ... lots of great stuff, with such a good visual scripting interface that you can use it to get (certain sorts of) kids interested in scripting and programming ...

Wealth redistribution

It seems to me that there are only two strongly justifiable rates for inheritance tax: 0% and 100%; everything in between is a compromise. Corollary: anyone who thinks an intermediate value is more appropriate does believe in some degree of wealth redistribution.

If you are right, Tim, and the money only stays in the family for a few generations, then I suppose it makes little difference that the wealth is temporarily concentrated in such a small area; it does eventually get redistributed by the market when a descendant 'pisses it away'. But what worries me is that the current trend in wealth inequality shows no signs at all of abating.

The problem is when wealth distorts democracy --- big fortunes, whether personal or corporate, are now increasingly used to affect legislation directly (through lobbying and campaign funding) and indirectly (through media ownership used to affect public opinion). This leads to a circle (virtuous for them, vicious for us) which accelerates and buttresses the inequality.

It is also starting to get to the point where you actually have to start with money to make money. Take a particular bugbear of mine: unpaid internships. Even in a society where, by and large, the concept of a minimum wage is accepted. it still seems acceptable for wealthy organisations to place a filter on the workforce to ensure that brains and hard work are not sufficient, you need wealth to start with. I'm not sure I find that acceptable, either on an individual or societal level.

"Great for you, I'd like to shift data between my home and my workplace faster than a cyclist with a 32GB USB stick." -- Stuart Longland

I agree - but, to be fair - I cannot remember a time when connected bandwidth, for anything over line-of-sight, was greater than sneakernet. You could carry 20TB of SSDs in a cycle pack without breaking a sweat - you could get a bike to 50Gbps no problem. A van full of LTO5 tape going 100miles is, what, 1000Gbps? A 747 full of Blurays going 3000 miles must be over 200,000Gbps. (Latencies being about 2-3 hours and about 6-7 hours, I'd guess.)

When thinking about, for instance, cloud backup and restore, you have to bear in mind that a 1 Gigabit/sec link is still only about 10TB/day fully soaked.

Bad news everyone: Cybercrime is getting even easier

Missing the point ...

I usually get downvoted for this, but I still believe that the existence of "malicious URLs" is nothing more than the existence of unacceptable browser flaws. Visiting a web site is 'opening a document'; and it is my belief that it should not be possible for data to subvert the application used for viewing that data and it should definitely not be be possible to subvert the system beyond that application.

How you supposed to even know if a URL is malicious until you've clicked on it, especially if it is shortened? Or in a QR code? Sure you can say oh, never click on a shortened URL, never scan a QR code, but then you are missing out on large chunks of functionality.
