Five billion phones are dead in drawers – carriers want to mine them

I didn't realise how hard it is to destroy HDs until I tried. "Bang a 6-inch nail through it", they said. Well dear reader, none of my nails were large enough, so I cadged one off a neighbour, and set to work with my DIY-sied hammer and the nail. All I managed to do was make a lot of noise, bend the nail and put a tiny dent in the steel case.

Best I could achieve was to prise off the circuit board, and hit the drives as hard as I could in the hope of smashing the platters or heads. Couldn't even get them to rattle.

Photos as evidence

I was given a copy of "Apollo Remastered" by Andy Saunders. A masterpiece. A large, heavy book with more black photo-ink than I've ever seen in one place. Some of the pictures make you just stop and marvel at what it was to be there, and really complement the text-based works on the Mercury, Gemini and Apollo programmes. I ended up reading it in small chunks, wearing my head-tourch on a diffuse setting, to help my aging eyes pick out the detail of the pictures and the sparse text provided with each.

Not proof that they went there of course, but a marvel of photographic restoration and presentation.

UI elements annoying Oi

Why oh why oh why do UI elements that require a Yes/No answer no longer use checkboxes/radio buttons? Looking at the Devclass article on Go on this very site, the cookie selection thing offers a load of horizontal sliders whose only selection state indication is to have the background in one of two slightly different shades of grey.

I can not determine whether I've turned them "on" or "off". Would some young person here care to explain why this is better than a checkbox or radio button. Is it simply because oldies did it one way, therefore it was obviously useless to the next lot, who needed to "refresh" it?

Please pay for parking – CMOS batteries don't buy themselves

Re: Parking

Not defending the Council's position here, but Government funding for Councils has fallen by ~50% between 2011 and 2018: "Local government has coped with a prolonged period of real-terms spending reduction which is without parallel in modern times. This large fall in local authorities’ resources has been primarily caused by very significant cuts in central government grants." [1]

At the same time, there are increasing demands for services such as health provision. People elect MPs who form the Governments that drive these changes, so it's a bit unfair to blame just the Councils for selling land and raising charges where they can. I wonder how many people who complain about "the Council" also cast their votes for the very people who engineer this situation.

Re: The future is laser (for me)

Bought my HP laserjet 1320n duplex mono in something like 2007 for something like 300 quid. Still going strong, even though it nowadays prints about one page/month. Never dries out nor fails, although the 16MB RAM may be a bit of a limit.

Apple seemed to remove the drivers with Catalina (and MS have also done so), but I just switched to a generic driver and carried on. Toner cartridges aren't chip-locked, so I'm able to refill them a few times - bought a soldering-iron hole borer and a bottle of toner powder & some bungs from one of the emporia who supply such things, and get about 4 fills per cartridge before the overflow chamber fills up. Makes them even cheaper.

Sadly, cartridges for the 1320n are getting hard to find now. Whatever people think of HP nowadays, this printer's been brilliant value.

And for a fictional account, the book "The Cruel Sea" is very good. Darker than the also-excellent film, it has a nice description of how the Escort Commander training course was carried out in that building, when Our Hero, newly-promoted to Commander, is given charge of an escort group.

Other good fiction is "Sharks and Little Fish" by Wolfgang Ott if you can find a copy, from the German perspective. Not for the squeamish. And "UMS Ulysses" by Alistair MacLean, for some honest thud & blunder.

Re: The world has plenty of plastic

Lost fishing nets are awful, especially the monofilament ones. In my younger days, I used to go wreck diving off the UK coast, mainly in the North Sea. Some of these wrecks had clumps of tangled netting, and the trapped, dead fish and crabs therein thus attracted further victims. There's no safe way for divers to remove this stuff in the low-viz, dark and tidal conditions, and monofilamnet is nearly invisible underwater, and practically impossble to cut.

I've also dived from chartered fishing boats, where fishermen would routinely discard cut ends of polyprop rope overboard with never a backward glance. This was a quarter of a century ago, so perhaps attitudes have changed.

Re: Not bad for the year -- but they may not be telling us everything

My first job in '86 as a new graduate was programming in PL/M on a huge, heavy blue MDS - double 8-inch floppy drives, with one disk for the system & the other for the code. Loved the clunk...clunk noises as the heads banged about during compilation. IIRC, we had an extension card so we could compile for the 8086-family in addition to the native 8085. They were on the way out when I joined, but still required for those working on System-X networking kit, which was being rolled out.

The MDS was networked to (I think) an NRM - a white really expensive server, about the size of a chest freezer, which also allowed serial-port-networked MS-DOS PCs to access the file system. It came with a multiplayer maze/shooter game called Snipes which ran on the client MS-DOS PCs, & the office used to ring with the yells of the slaughtered.

We subsequently bought two Intel ICEs to do embedded 80188 development - these were the beasts with the great spider cables, which as the OP states, were plugged into the target system, having removed the target's actual CPU. I was working down in the bowels of our team-written embedded OS, writing C in MS C 5.0 (which had a preprocessor bug that couldn't correctly expand our huge macros, themselves auto-generated via Intel's AEDIT scriptable editor, run as part of the build process). Code had to be compiled, cross-linked, burnt to EEPROM, walked down the corridor, plugged in, powered up etc. in an endless cycle of fun, with much staring at oscilloscopes and HDLC protocol analysers. Strange what you remember - happy days.

Take-off crash 'n' burn didn't kill the Concorde, it was just too bloody expensive to maintain

Re: Supre Cruise

Yes, SR-71 was a bit different though, because they could exceed M3. At those speeds, the compressor of a jet is almost becoming a drag item, & SR-71 bypassed most of the air directly through some big 'drainpipes' along the outside of the casing. They were essentially running almost like a ramjet at those speeds, with little compression & just igniting fuel in the airstream, running on reheat (afterburner for our left-pondian friends).

The big spiky-things at the front of the Blackbird engines moved forward & rearwards to manage the shockwaves. Unstarts in the intake could be extreme in the Blackbird, and at least one was lost because of this. A pilot's helmet was cracked by the force of his head hitting the side as the aircraft as it yawed during an unstart.

Concorde got the sweet spot of speed & performance. Trying to go faster would require more exotic fuselage materials & getting certification for safe operation faster than M2.abit with paying passengers rather than steely-eyed fighter jonnies would, I suspect, have been too difficult & costly - the Americans spent 1BN USD developing a faster passenger jet than Concorde & gave up.

As someone else says, there's tons of info on pprune, & there's also the heritageconcorde site, & several really good books, & the itvv.com Concorde flightdeck DVDs, which after many years are about to stop being made. If you're going to buy anything, get the itvv dvs.

Re: Supre Cruise

Bit of background, & a quick ramble. Jets work by ingesting air, compressing it, lighting it & shoving the expanding gas out the back, in a continuous process (unlike pistons, which are discrete such, squeeze, bang & blow of course). You can either accelerate lots of air a bit (modern high-bypass turbofans), or less air a lot (very noisy, uneconomical turbojets). However as you go faster, the efficiency of fans drops, & that of the pure jets increases, in simple terms because you need less 'compression' the faster you go. Also as you go faster, you need faster air coming out the back, & jets push the air out faster than fans (huge simplification here, please accept that!).

So for supersonic, you either need low-bypass fans, or pure jets. You also need loads of thrust. One way to get this big thrust is to use reheat, where you squirt neat fuel into the exhaust, downstream of the turbine, & light it, adjusting the nozzles at the back of the engine to compensate for the pressure changes at the back when you start this additional generation. You also want to keep some lower-speed & higher-pressure air coming out the back as well, in a 'cylinder' around the higher-speed supersonic air, in order to (a) make it quieter, & more importantly (b) to stop the cone of supersonic air expanding (diverging); you want the thrust to go straight back & not be wasted as the air expands in all directions.

Using reheat is horribly thirsty, but it means that you can have a lighter, "less powerful" engine for the majority of time when you don't need it. Generally, engines big enough to sustain supersonic flight would be massively overpowered for other times (and remember twin-engine airlines have loads of excess power too, since they must be able to get off the ground if one fails).

However, with careful magic in the intake & exhaust (and clever wings & fuselage to reduce drag), you can do away with reheat, & 'supercruise' on 'dry' power. There's a lot of extra drag when transitioning through M1.0, but it reduced again by M1.7 in Concorde's case, & she could then supercruise, on full dry power, with no reheat. Reheat all the time would use about 4x more fuel.

Concorde was unique here, with about 8% of the thrust coming from the engine itself, 63% from the intake, & the rest from the convergent-divergent nozzle system at the back. So supercruise is just very clever optimisation of the intake/engine/exhaust system to optimise power & efficiency at supersonic parts of flight.

The really clever thing is the intake on Concorde, where you're slowing the air down by 1500MPH in a length of 15 feet, without expelling a shock wave out of the front of the intake, since to do so would multiply drag, & bad things would happen (this is termed an Unstart). Managing this shock front an the multiple shock waves dynamically is an amazing thing.

The most amazing engineering

When the project was cancelled, the very next airframe would have been the 'B' model, with wings that were more optimised for low-speed operation, & more powerful engines that no longer required reheat, which even though it was only used for takeoff & for about 13 minutes from M0.95 to M1.7 was very thirsty. This would have enhanced efficiency, but none were built.

The engineering, particularly for the engine intakes, ramps & spill doors & their control was staggering for the 1960s. at M2.0, more than 60% of the thrust was generated from the intake, from energy recovered from the pressure changes, with vary rapid adaptations for temperature, air pressure, demanded power etc. Concorde could lose two engines at M2.0 on the same side with no fuss, other than very rapid deceleration.

Even things like the tyres were radical, since the delta produces no lift until rotation, unlike conventional wings that start to reduce the tyre loads as speed increases. So you have an aircraft with a much higher take-off speed (1/2mv^^2 & all that), with all its weight on the wheels, requiring new tyre technology. And the main gear legs are too long to fit in the bays, so they have to shorten as they retract. Amazing, wonderful white bird, the like of which we'll never see again.

"...He sprang to his feet and saw to starboard, and not a hundred yards from their heeling, pitching boat, a vast iron bulk like the blade of a plough tearing through the water, tossing it on either side in huge waves of foam that leaped towards the steamer, flinging her paddles helplessly in the air, and then sucking her deck down almost to the waterline.

A douche of spray blinded my brother for a moment. When his eyes were clear again he saw the monster had passed and was rushing landward. Big iron upperworks rose out of this headlong structure, and from that twin funnels projected and spat a smoking blast shot with fire.

Last flying Avro Vulcan, XH558, prepares for her swan song

Re: It's wonderful, but...

It's not just the people. The rules around 'complex'-class aircraft are akin to modern airliners: there must be a full paper audit trail of every nut, bolt & widget, bonded-warehouses etc. There are no more zero-hour Olympyses, and RR no longer have the tooling or the processes to make them. As a commercial organisation, you can imagine the publicity if anything did happen to these 30+ year-old engines. Then there's the other critical systems and airframe fatigue - same applies.

People cite the marine Olympus, but it's a different beast: similar design, but non-aerospace components (weight doesn't matter in a ship, and aircraft generally don't eat salty air). 558's restoration only flew (ahem) because there were 8 zero-timed, bagged & audited Olympus 201s available from the old stock. Similar story with Concorde: without the approval of the Design Authority organisations, there would be no hope whatsoever of return to flight.

Re: Seen it a few times

Minor nitpick, but the Vulcan didn't have afterburners (reheat). It used either Olympus 201 (the ones in XH558, & the ones that can make the howl), and the more powerful 301 (which seemed never to howl), and were used in the Falklands missions. The two types were not interchangeable.

It's mostly lack of available engine hours that's going to ground 558, however like the other two live vulcans (and the two live Victors), she'll still be able to do fast taxi ground runs.
