If the U.S. government did this for U.S. companies with U.K. data, you'd be mad.

The US PATRIOT Act - and probably its equally stupidly-named successors - did exactly that. I was working on the last Census in the UK, and know damn well the steps that had to be taken to make sure that no one from the prime contractor - Lockheed Martin - had any access to live data or systems.

OK so the U.S. government has occasionally TRIED this sort of thing themselves, and that's the point. Our laws and courts kept them from being able to get away with it.

No. Your laws enabled them to do this. And probably still do.

Health Sec Hancock says UK will use Apple-Google API for virus contact-tracing app after all (even though Apple were right rotters)

smudge

If you walk past someone's phone, presumably that counts as "contact", rather than any actual physical contact.

I don't think so. I'm pretty sure that time comes into the equation as well, so that you would have to spend, say, 15 minutes with someone closer than 2 metres before "contact" was registered.

Re: distance and signal strength

At any events the radio transmission time is going to be swamped by the variability in the time taken by the electronics to respond. It'd probably end up being 2 +/- 100 metres

I have no experience in this field, but I assumed that you would fire off lots of signals and "average out" the response times to estimate the distance.

Where "average out" is a layman's term for "perform some pretty sophisticated and complex analysis".

Re: distance and signal strength

Would sonic methods work in noisy environments such as London Underground platforms and trains? Which is precisely the type of environment - lots of close contact with strangers - where the app would be most useful.

80-characters-per-line limits should be terminal, says Linux kernel chief Linus Torvalds

smudge

It won't print past column 80!

Gives me an excuse to drag out my old story about a DECWriter - basically a hardcopy terminal - back in the early 80s.

One day it started refusing to print anything beyond column 80, no matter the length of the line. If the line was longer, then it would print 80 characters, then carriage-return line-feed, then continue the line.

80 characters - very significant! We spent days checking and re-installing every piece of software we could think of that might be causing the problem. But it still wouldn't print beyond column 80.

Then I decided to actually look at the DECWriter itself. And discovered a pencil that had fallen into it and become jammed.

It was pure coincidence that it was after column 80 that the print head encountered the jammed pencil and took evasive action.

This'll make you feel old: Uni compsci favourite Pascal hits the big five-oh this year

smudge

But who remembers Concurrent Pascal?

One of my first professional jobs, at the end of the 70s, was working on a project to build an easily programmable multiprocessor system using Intel 8086s and the Concurrent Pascal system developed by the Danish comp sci Prof, Per Brinch Hansen.

Concurrent Pascal was a high-level language for systems programming, and included concurrent processes, classes, and monitors for controlling access to shared resources. A small machine-dependent kernel provided things like process scheduling, interrupt handling, and basic I/O. There was also Sequential Pascal, a flavour of the standard language, for writing applications.

The compilers for these languages produced p-code, reverse Polish instructions for a stack machine, and these were interpreted at run-time by a machine-dependent interpreter which was another part of the kernel. One of the things we did was change the back-end of the compiler so that it produced directly-executable 8086 machine code. Execution speed was not a problem, but memory was expensive, so we added optimisation for code size, and ended up producing more compact code than Intel's own Pascal compiler.

The multi-processor system worked, but we never got as far as making it resilient. Each processor was in its own cage, with its own memory, power supply, and link to the comms bus. Hence one demonstration when someone asked "How do I know that it's a multi-processor system?". I said "You can turn any one of these processors off." "And?". "And the whole thing will stop working!". :)

Re: Network latency?

Many thanks for that - a very informative and helpful answer!

smudge

Network latency?

I am not a network person, so please bear with me. My question is, how much could the synchronisation be screwed up by network latency effects?

Different viewers could be in different parts of the country, using different ISPs, and with different equipment and quality of connection between them and the Beeb.

To enable people to enjoy a big reveal or a punchline together, the sync would have to be pretty good - no more than a second out, say.

Even assuming no buffering, which would really screw things up, how feasible is it to maintain almost perfect synchronisation over, say, an hour?

Re: No love for CORAL 66?

It turned out the FORTRAN compiler on the VAX was actually quite clever.

Unfortunately, their CORAL-66 compiler thought it was clever too.

The first professional job I ever did was to help track down a bug in a sonar simulation system, written in CORAL-66 using the MASCOT methodology (defence bods will remember that). It always eventually crashed with a stack overflow, though the amount of run-time before the crash varied considerably.

Turned out that inside a double, nested FOR-loop was an IF statement of the form IF <x> AND <y> THEN... , where x and y were complex expressions.

Of course, if x turns out to be false, you don't have to evaluate y. So the optimising compiler added a jump to the next thing, which happened to be outside of the nested loops. But it left the temporary result for x on the stack. So eventually there would be an overflow.

The number of iterations of the loops and the value of x depended on the input data, but also on how much time the scheduler gave to each of the "concurrent" processes in its simulation of a real-time system. So even if you fed it the same input data, it would run for different times before crashing.

I remember going to a DECUS meeting to tell everyone about this. But it turned out that we were the last to know :(

My first computer language...

... was Algol W, at university in the mid-70s. Sequence, selection and iteration - what more do you need? :) It set the way for how I think about programming, and I found it difficult to think in other ways. For example, we later covered the functional programming language SASL (a precursor of Miranda, which in turn preceded Haskell), and I found it almost impossible to think that way, until one day the penny simply dropped, and I had no problems after that.

For Raymond, up above, I still have my copy of the MoD "Blue Book" standard for CORAL 66. Used that at university on a CTL mini, and in professional life on Ferranti Argus and CTL/ITL minis.

My real love was Pascal, and I remember how chuffed I was the day I discovered that although I had been using it for many months, I hadn't realised that our implementation of it did not include GOTO statements! I still have a free implementation of it on my home PC - very useful for occasional puzzle solving.

Others I used included Fortran IV and BCPL at university, and ASM-86, PL/M-86, and PL/I in professional life.

But then I became a consultant :)

UK finds itself almost alone with centralized virus contact-tracing app that probably won't work well, asks for your location, may be illegal

smudge

Re: It asks for your location?

The idea is that if you notify the app that you have symptoms then "they" send you a test. If you prove positive then they send tests to your contacts.

The question that I can't find an answer to is this - if the self-declarer's test proves negative, are that person's contacts informed that they are free to go?

Otherwise there are going to be a hell of a lot of people needlessly self-isolating for 14 days. Repeatedly, if they are unlucky.

All the descriptions that I can find seem to stop at the point where contacts of a self-declarer are told to self-isolate. Clearly, that is the safest thing to do, but in the absence of any follow-up it means that there will be an awful lot of false positives, or false "maybes".

The answer to my question may well decide whether or not I use the app.

Re: You are not really familiar with computer security, are you?

Now try to imagine to secure a building where fences have holes you cannot see....

So you encrypt your data when it's at rest.

You may not see the holes, but you should know where they will be. You set up firewall rules with a whitelist for the only permitted external connections. You disallow externally initiated conections through the firewall, although I'll accept that in this case the ransomware probably initiated connections from inside the firewall - though it's still worth seeing what you could do in that area.

And ultimately, of course, if the sensitivity of the information is great enough, you air gap your systems - with no connections to the outside world.

And so on....

Re: Huawei Cyber Security Evaluation Centre (HCSEC)

I wonder why. They are obviously not concerned with protecting Chinese state secrets here.

Because, O Brain of Britain, finding a backdoor or, more likely, a vulnerability in a piece of Huawei kit which may also exist in sensitive networks in the UK would be a matter of UK national security. It also facilitates discussions with the spooks about the possible implications of bugs and vulnerabilities in such equipment.

And, oddly, it probably reassures the Chinese that the UK is taking this seriously.

Re: Nothing new

When I was in my early 20s - 40 years ago :( - I could hear ultrasonic motion detectors. And bloody painful they were too. On a couple of occasions - once in a pub and once in a big house, neither of which I had been in before - I actually proved to the dubious that I could do this, by pointing out the locations of sensors which none of us could see because they were hidden behind curtains.

A few years later - approaching 30 - I was working in an office in a big country house. Every now and then - and it seemed to be roughly the same times every day - I would be conscious of this very high pitched sound that no one else could hear. At least it was soft, and not painful. Eventually I realised that the estate manager would take his dog out into the grounds at these times, and this was him using a dog whistle to summon the pooch.

A couple of seconds' research suggests that I was hearing sounds at 25Hz or higher. Needless to say, that ability disappeared long ago.
