Nice thought, but, Skippy ran in, duffed 'im up and was away while the canopy was still flying, and it lay nice and still on a very smooth bit of cement when it was collapsed. Besides, what a fabulous place for a spot landing. Dropping onto it just had to be done.

Does the Home Office official who authorised the Windrush landing cards to be discarded without first checking that there were electronic or microfilmed copies still have a job?

If so, why?

Re: I'm planning aa marathon

I'd give "The Right Stuff" a miss and read the book if I was you. I really enjoyed that the first time round and, years later, its still good value. OTOH I was really disappointed by the film: I saw it on first release and never want to see it again - far too artsy and not nearly enough Right Stuff for my taste.

Read the book and then follow it up with Michael Collins's "Carrying The Fire".

Re: If it wasn't pathetic, it'd be almost funny

The Americans have done the exact same thing: introducing new and incompatible standards, just because they can, in a rather more critical area: aircraft flight conflict resolution.

The world solved this problem by extending an existing system, which uses mode C transponders, by adding an ES data packet that includes the aircraft's velocity vector to the transponder response. This allows TCAS equipment in aircraft carrying it to compare its vector with that of nearby aircraft to tell the pilot that there's a problem and how to resolve it and the transponders still work correctly with existing secondary radar systems, which simply ignore the ES data.

The Americans decided this wasn't nearly good enough and introduced UAT. UAT does more or less the same thing BUT all signals have to go through a ground station: UAT equipped aircraft do not talk to each other, only to a nearby ground station. The ground station does the conflict resolution and broadcasts avoidance information to the affected aircraft. This is is totally incompatible with the internationally used Mode C+ES and TCAS system so aircraft need to carry UAT kit as well as a Mode C+ES transponder if they want to see both systems - needed by airliners inside the USA because the FAA pushes UAT use for light aircraft rather than Mode C+ES. On top of that it uses different frequencies, provides at best only patchy coverage of the continental USA due to a lack of ground stations in parts of the country and is not used outside the USA. But US equipment manufacturers love it - of course!

Re: Wasn't this handled last time?

This is OTT for the "First GPS Millenium", but...

Yes, I'm well aware of who firebombed Tokyo and why. I'm also aware that some other cities, among them Hiroshima and Nagasaki, were deliberately not bombed with conventional weapons so that the strategists could get a better assessment of the destructive abilities of atomic weapons.

There's a lot about this in Richard Rhodes book "The Making Of The Atomic Bomb".

If you want to understand the scientific and political background to the Manhattan Project as well as learning about the politicians, military and scientists involved and other country's atomic weapon projects (yes, Japan had one as well), this is the book to read. Another title for it could have been "The History of Atomic Physics: 1995-1945", possibly more accurate but a lot less likely to attract readers.

Martin Gregorie Silver badge

Re: Wasn't this handled last time?

Yes, I remember the panic - but it turned into a non-event. Even my old Garmin GPS II+ handheld satnavs sailed through it with no problem and I fully expect them to do the same this time.

IIRC the only GPS receivers that didn't make it through last time were all in Tokyo taxis. This was certainly bad news for them, and here's what I was told about that at the last GPS roll-over:

Tokyo was heavily firebombed in WW2, and since close-packed wood and paper houses burn really well, the city planners must have started again from scratch. The rebuild had to be fast because almost all houses were destroyed and winters are cold, so in the hurry to rehouse people, the houses were numbered in the order they were built in each block. As a result the numbers along a street are in pseudo-random order, so Tokyo taxi drivers really need a working GPS with a map showing house numbers. Either that, or they'd need years to do 'The Tokyo Knowledge', assuming there is one, before getting their license.

I just wish I could say the same about the "news" on the BBC website, which seems to be 95% dross, rather nauseous dribbling over celebs and "human interest" stories.

I can't comment about their TV news - or anybody else's TV news for that matter - because I manage very nicely, thank you, without a TV set in the house. And, no, I don't watch TV on catch-up - news or otherwise.

Re: What can you fit in 25kg...

As far as I know there are currently no military aircraft, apart from a few U-2s, that can operate at 67,000 ft., so for all practical purposes its above any other aircraft that is likely to be flying over the UK.

NOTE that, rocket planes and U-2s excluded, it seems likely that the highest flying aircraft today is Perlan 2, a pure glider, that is awaiting confirmation of a record for its flight on September 2, 2018 which reached 76,124 ft in Patagonian mountain wave off the Andes.

Re: SS7 hacked?

Reading slightly between the lines, it appears that SS7 was introduced in the early-mid 70s to prevent phone phreaking and the resulting loss of telco revenue.

SS7 doesn't map onto the OSI comms model very well and security seems not to have been a priority - as if its designers thought "its digital, so attacking it is well beyond the capability of the phreakers". Besides, originally SS7 protocols were only used for inter-exchange communication and so never reached an end-user phone.

Then time moved on, mobile phones were invented and these adopted SS7 signalling because it was there, 'just worked' and SS7 capabilities were needed to manage tasks such as handing on calls from one cell to the next. So now SS7 messages do reach end-user kit, which makes them both interesting and much more accessible to phreakers and other black hats.

The main changes since then seem to be that other data handling services, such as SMS message, 2FA authentication, etc., have been layered onto SS7, which, at a guess, is still an unencrypted channel.

So, given this history, it shouldn't be a surprise that miscreants are now targeting SS7 for nefarious purposes such as syphoning off any security data that it might be carrying. This was always bound to happen and the only surprise is that its taken so long.

...haven't seen one, and its MUCH faster than Clonezilla and easier to use, too.

Couple of years back I put a 128GB Sandisk SSD in an old Lenovo R61i when its 120GB hard drive died, installed Fedora from a CD. Booted up, pulled in my stuff from a backup. No problem. Still going like a train.

Bootnote: I'd wanted to install another hard drive, but R61i electronics can't handle a disk bigger than 250GB and it was already impossible to buy a replacement HDD that small, hence the 128GB SSD.

Re: 500g Drone vs 100 ton airliner

how big was the bit of debris that killed the Parisian Concorde?

From Wikipedia:

"A titanium alloy strip that was part of a DC-10 engine cowl, identified as a wear strip about 435 millimetres (17.1 in) long, 29 to 34 millimetres (1.1 to 1.3 in) wide, and 1.4 millimetres (0.055 in) thick.

The Concorde ran over this piece of debris during its take-off run, cutting a tyre and sending a large chunk of tyre debris (4.5 kilograms or 9.9 pounds) into the underside of the aircraft's wing at an estimated speed of 140 metres per second (310 mph). It did not directly puncture any of the fuel tanks, but it sent out a pressure shockwave that ruptured the number 5 fuel tank at the weakest point, just above the undercarriage. Leaking fuel gushing out from the bottom of the wing was most likely ignited either by an electric arc in the landing gear bay (debris cutting the landing gear wire) or through contact with hot parts of the engine."

Markov rules

Just for giggles, I fired up my Markov chain implementation, in Java, and fed it El Reg's test data set. Here's the first 250 words:

"I want to kiss your lips I love you.

Oh, if only you I am in love with you is the greatest thing that has ever happened to me, and I've never been happier in my day, I always know it will be a good one because at the end of it matters because I'll soon be in your arms.

Thank you for being my vacation from the rest of the only ways to get out of a tight box is to have succeeded."

From this and a few other runs that produced similar results, I reckon Ye Olde Markov Chayne beats the pants off AI, not only for readability, but especially in terms of cost per Kloc of code written (50 Java statements, 0.05 Kloc) not to mention run time and CPU used ( 84mS run time, 108 mS cpu for 250 words of output on a Lenovo T440).

Dozens of .gov HTTPS certs expire, webpages offline, FBI on ice, IT security slows... Yup, it's day 20 of Trump's govt shutdown

Martin Gregorie Silver badge

What redress does a US citizen have if a Presidential order harms him without a declared emergency, as has happened to all the governmental employees that got sent home without pay?

I'm genuinely puzzled as to how Trump was able to shut down government, not least because I've seen nothing in the news that said what regulation was used (but I may have missed it). I did a web search as well but found nothing that looks directly relevant, which is odd, because past experience with the FAA makes me think that everything done by and to the US Government is governed by minutely detailed regulations. From what I found the options seem to be:

- executive order. But doesn't that require an emergency to be declared?

- vetoing or refusing to sign a Congressional bill. But doesn't this mandate resolving it with Congress?

...but none of these appear to allow the sudden, unconditional and uncontested shutdown that happened.

What have I missed?

Re: How many Shuttles could have been kept operative..

Those things were dangerous and inefficient.

Read Mike Mullane's "Riding Rockets" for a detailed description of just why the Shuttle was dangerous by design and how this was compounded by NASA HQ's array of PHBs and politically appointed numpties making the decisions.

Mike Mullane was a Shuttle-era astronaut and a very brave man who flew three missions despite knowing all the ways it could kill him and that its 'escape system', i.e. sliding down a pole wearing a parachute, was only usable before it had passed 50,000 ft on launch.

To appear as a single event, the signal pulse can't last longer than the time it takes for light to travel from one side of it to the other. It takes light 3mS to travel 1000km, so something capable of generating a pulse a short as 3mS cannot be more than 1000km across.

Re: Ironic then that Israel and Iran are antagonistic to each other.

"Can you remember when Iran used to be liberal?"

No, I can't. That would have been a LONG time ago - back when Mohammad Mosaddegh was the Iranian Prime Minister, so before 1953. That was when Reza Pahlavi was made Shah by a Brit/US coup engineered to protect oil company revenues from paying Iranian taxes. Reza Shah was pretty damn illiberal. His family seems to have had both hands in the till while he built up the SAVAK to stomp on anybody who objected.

I travelled through Iran three times in the '70s. In '73 you had to know what was going on and look under a stone or two to see what the SAVAK were up to: I was not aware of them. But, by October '77 they were pretty much in everybody's face. However, a lot changed in the next six months. In May '78 it was obvious that the Shah was about to be shown the door. Iranians I'd never met before would tell me how much they disliked the Shah while chatting in the streets of Mashhad.

It was very unfortunate for Iranians in general that after the revolution, the Ayatollah Khomeini turned out to be just as autocratic as the Shah had been and, worse, not only took over the SAVAK lock stock and barrel (renaming it slightly in the process), but made it even more powerful.

Re: It's fascinating to see how people are so much behind the times

The problem is that critical thinking is still not taught at any level and people are also not taught how to recognise people exploiting logical fallacies to spread total nonsense, or question why things are being presented in the way that they are.

Spot on!

There only four things that schools need to teach:

  • Critical thinking / the scientific method
  • How to learn
  • The ability to read the local language and to write it clearly and simply
  • Basic numeracy

With these taught properly, virtually all other subjects, apart from sciences and manual skills, can be self-taught as needed and individuals will have the tools to distinguish truth from lies and fantasy.

Of course this will never happen because politicians would never allow it.

Re: Saving democracy

Anonymity, protecting the innocent from trolls since forever.

I disagree with you here: if there was NO anonymity on-line that would almost certainly get rid of the vast majority of trolls, stalkers, confidence tricksters etc. but it would be very hard indeed to implement securely enough to make it work.

The few legitimate uses [*] for anonymity, e.g. whistle-blowing, should be easy enough to handle via anonymising servers by ensuring that incoming messages are securely sent only to the owning watchdog organisation and responses are only sent to the originator.

Boffins build blazing battery bonfire

Martin Gregorie Silver badge

And a few dozen other pumped storage power stations worldwide?

Sure they exist - where the landscape topology and underlying geology make it practical to build high and low ponds that are leak-free and unlikely to be harmed by earthquakes - but there aren't many suitable places to build them and the total energy they store is tiny by comparison with the energy flows in the electricity grid they're attached to. IOW the pumped storage capacity is too small to make much contribution to balancing energy supply against demand.

OTOH including a suitably sized storage battery (using silicon, molten salt, flow technology or whatever) as an integral part of a renewable energy farm seems like a good idea, especially if national grids are redesigned to act more like a set of interconnected regional grids. Co-location makes the losses due to high energy flows between energy sources and storage batteries easier to minimise because the links would be very short.

Why is insecurity 'inevitable'?

Subject says it all. It doesn't seem so inevitable to me.

Given that many of the light-weight realtime OSes you might find running instruments such as oscilloscopes often have little security [1], an obvious, simple and cheap way to secure the instrument would be to fit, say, a RaspberryPi model B inside a spare corner of the case and use it as a built-in network front end. For very little money this would provide a firewall and a reasonably capable login mechanism in addition to acting as a GUI for the 'scope. As a bonus it could also buffer and queue output sent networked printers and plotters or support one or two USB connections to local devices.

[1] I used Microware's OS/9 for several years. Its a capable and very reliable OS both for desktop and realtime uses, but security? not so much apart from a login and file permission bits which are there as much for keeping the idly curious out and protection against fat fingering: you can easily run it in single user mode if you want. In this I don't think its all that different from any other small realtime OS.

Re: Spoilers in Tech Docs!

You start with a "Header" that documents what the procedure does,

Absolutely essential while writing Java, but if you go quite a bit further you'll have something that anybody can understand and, better yet, YOU will understand if you need to tweak it in a year or five.

  • The class-level description needs to say what the CLASS is intended to do, no more and no less, though it may also be a good place to describe the meanings of any public constants
  • The method level descriptions can be quite brief. They should give guidance about when to call them, unless they're a simple getter or setter, but should not paraphrase any of the @param annotations
  • This documentation must be run through javadoc and read to check that it makes sense

If you don't do all the above BEFORE you write more than than a skeleton class and methods then (a) you probably haven't thought the class design out properly and (b) for sure you'll piss off future developers.

The same goes for writing C except the the 'class' level stuff goes at the top of the source file and you need to check what's in your comments by running the code through your chosen documentation tool.

Last but not least, if the class or function package does anything thats even slightly complex write a test harness and a set of regression tests that get put into version control and/or backed up with thre code it tests. A PHB will tell you this is not necessary and/or a waste of time but IME he will be very wrong. A well-considered set of regression tests (covering simple usage, edge cases, and as much misuse as you can imagine) will save a LOT of wasted time and swearing. The test harness need merely take a line such as

methodname param1 param2 ... # comment saying what you expect

and split out the method name and parameters into an array of, say, strings and ints before executing an if.. then.. else.. totem pole which calls all the methods and displays all results interspersed with a listing of the test script. Dead simple: no conditionals needed because you can simulate that by the order of method calls in it.

If you're clever, you'll put all the script reading, parsing and printing into a driver structure that can run scripts against plugins that are specific to the class being tested and add something that compares test output with a set of expected results: a regression test pass is when the comparison produces no output.

Re: Zero Exhaust?

Of course MS could *add* such a configuration parameter. But it was implied that they've already done so - in which case it's a question of how to find it.

Yes and No. In two places the article says there is no way to disable slurping and then the Zero Exhaust system is mentioned with an (apparently) documented slurp control switch. The crux of the biscuit is: if that's already out then they could simply make the Zero Exhaust version the mainstream product and put it on immediate release.

So why do they need five months to do something that should be so simple?

Mything the point: The AI renaissance is simply expensive hardware and PR thrown at an old idea

Martin Gregorie Silver badge

Re: Quite.

But there's a HUGE difference between the human child and today's AI systems: when the child comes to a conclusion you can ask them to explain why they think that is so. You can't do that with any current AI system.

So, my take on this is that, if/when you can ask an AI to explain how and why it did or deduced something, then it actually is an AI. If you can't ask it that question and get an understandable answer then what you're dealing with is definitely not an AI and may well be just a dangerous piece of junk.

There are real-world ramifications too: if an autonomous car crashes or kills somebody you need to know why that happened and the ability of the car to tell you (or not) is likely to have legal consequences. If it can explain itself, it and its driver and builders may be shown not to be responsible for the event: if it can't then responsibility should automatically pass to the driver and builders.

Re: Where's Rutherford?

And add in James Chadwick, who discovered the electron.

John Dalton should be there too, as the first scientist to put atomic theory on a usable basis and make it the foundation of chemistry.

However, atomic theory was all a bit theoretical until Chadwick discovered the electron, proving that the were smaller particles than atoms, and Rutherford discovered that the atomic nucleus existed and was very much smaller than the atoms that contained them. This led directly to the Bohr atomic model and so to modern nuclear physics.

As far as I know none of the three - Chadwick, Dalton and Rutherford - have much recognition outside science: none are as well known as they deserve.

Yes, VMS cluster, Solaris cluster, Veritas cluster, they all do that for local HA, and it works. Disk vendors like EMC and HDS can also do it for their distributed storage.

Don't forget Tandem NonStop systems, which distributed the whole kit and caboodle (CPUs, disks, disk controllers) over geographic distances as a networked set of up to 16 nodes, each containing between 2 and 16 CPUs with all hardware duplicated and hot-pluggable. The whole distributed system was fault tolerant by design with automatic fail-over for all components. Result: 99.99% up time.

... and that was early '80s technology, so there's really no excuse for current systems supporting worldwide 24x7 services to offer less guaranteed availability than was available in 1984.

Re: Old is good

A garden gate's purpose is to be opened let somebody through and closed to keep them out - full stop.

Fitting a rain gauge is a backward step: it not only adds unwanted complexity, but degrades rain measurement due to spillage when the gate bangs in the wind.

Re: US military services

I'm not American: in countries where I am a national the Coast Guard is a branch of the Navy, so it never occurred to me that it wasn't part of the USN.

AFAIK the Space Force is still pretty much a figment of the Trumpian imagination.

Put it this way, I've seen nothing about the USSF since the first announcement. In any case, to be a real Space ForceTM, it should surely control all US nuke-tipped missiles, ABMs and manned military space vehicles, but as the missiles and ABMs are currently owned by the USAF and USN I imagine these outfits are lobbying hard against giving any of them up. So far there are no manned military space vehicles and no announced plans to build any. So, with no hardware of its own and nothing being planned for any time soon, the USSF is just a Governmental boondoggle.

The US airforce, army, marines and navy*, all speak Army Creole. For a concise definition and examples, see the Urban Dictionary.

Tom Wolf's "The Right Stuff" contains a more graphic description of Army Creole: Chapter 6 'On the Balcony', 11 or 12 pages in - page 119 in my copy.

'The Right Stuff' is a much better book than you'd expect if you've only see the rather pathetic film. It's still a very good read that offers insights into the lives and backgrounds of the pilots who became the Mercury Seven at the beginning of the space race and of NASA.

* The US military services are listed alphabetically - no form of ranking is implied.

All parachutes need plenty of height to deploy: very few people have survived a bail-out under 2000 ft. That said, a whole-vehicle recovery system should work from a lower height because it is designed to lower the aircraft with the people still inside, so there's no bail-out needed and the only predeployment activities are to realise there's a serious problem and to pull the red knob.

However, even the rocket-extracted Ballistic Recovery System isn't guaranteed to give a safe recovery from less than 400 ft in straight and level flight or from less than 1000ft if the aircraft is spinning. Almost any other imaginable circumstance is likely to have a safe recovery height within that height range, though there doesn't seem to be much, if any, data on how well a BRS system would deploy after engine failure in a hovering aircraft which would still be falling relatively slowly.

But, IIRC all the above minimum survival height estimates assume deployment is over flat ground, so no allowance is made for the incident occurring over trees, tall buildings etc. or the possibility of the aircraft colliding with something while the chute is deploying and the plane still has significant forward speed.
