Re: Bah!

I bought a trivial low power 12V plug in from Maplins (RIP UK supplier of electronics kit) about a decade ago. I plugged it into my wall outlet and there was a big bang and the main 32A breaker tripped. I removed it and there was a notch missing from the copper so proving the well known truism that fuses blow after the damage has happened.

I took it back to Maplins for a replacement and insisted that they plug the new unit into the wall there before I accepted it. She did so with notable hesitation and a worried look but it was fine

Re: Poor flake

Lets raise a pint for Lester Haines. The special projects bureau is much missed and Lohan seems destined for a life without the airborn glory (and probable disaster) that it was born for.

I was thinking the same. The wild west of IT has passed and we are now in a stable state where most things are done using established tools so the possibility of a bad command is greatly reduced. Clicking SnazzyExpensiveBackupSolution on the deskop is going to have fewer routes to disaster than a mistyped dd command.

I still do my backups with dd though so maybe there will be a post from me in the future but as I am careful then nothing can go wrong!

OK this one was feeble but in general I enjoy these and on a Monday my acceptance criteria is low so please keep posing them and I am willing to take the good with the bad.

I don't have any stories myself but I do know of someone who blew up the electronics of a significant instrument when at a antarctic research station at the beginning of winter with no possibility of repair for 10 months. This would have been a great Who? Me? but it is not for me to tell.

Overhead projector rolls were the worst

I was at uni in the era of overhead projectors. The single sheets were bad enough but one of our lecturers (I think it was thermodynamics) used the continual strip on rollers and slowly wound it on as he talked. He gave out no notes so every lecture was just frantically copying the content including graphs into our notebooks. It was basically impossible to keep up so the notes were very poor. He was explaning the content as it was passing by but we were far too focussed on copying to listen to a word he said.

In hindsight it might have been better to ignore the visuals and just listen to him but I really don't know as I never had time to find out what he said.

Our lecturer in stellar dynamics had the opposite strategy and on day 1 handed each of us a copy of the notes. From then on we listened to everything he said and annotated our notes as appropriate. Thank you Kaz Krynicki - you were great (sadly I just googled him and he died in 2019). No idea who the thermodynamics lecturer was.

Imagine you are the person at CERN who decides to send releases the press. CERN and the high energy physics community in general are very excited about the discovery of a X (such as pentaquark or splitting the thaum) with all the implications for the standard model / theory of your choice.

This person knows that they will be asked by the press to elaborate on the significance and maybe even give interviews about it.

Would you want to be the person who has to explain quantum chromodynamics to The Sun? It must be a tough job!

Re: Ever get the sense...

OK I accept the challenge.

Grand piano is about 500Kg. Lets skip over the messiness of colliding 2 of them and just throw a single piano to the ground at 99% speed of light. It hits with about 2.7E20J of energy which is about 67000 MT or 1350 times as big a bang as the biggest nuclear bomb ever exploded.

Putting it another way a piano at 99%C hits roughly as hard as a 2E12 Kg asteroid coming in at a modest 15 km/s or about 0.0001 as much bang as the dinosaur killer of 65 million years ago.

Whisper - no one tell them that 5G phones might run at well above 5 GHz - they might panic even more especially if they discover that the screen they are looking at emits radiation at 50000 GHz!

That is the only way for this to make sense. Thrusters require control but if this is a passive watchdog that eventually triggers unless a widget is powered up every day then it would work on dead spacecraft.

Sahara is the long term renewable energy source - just stop fighting and get it sorted!

If a sahara country builds a megascale solar plant then they would become the next saudi arabia but with better long tern prospects. There will be nutters who want to blow things up for no good reason but this is always the case and solar is more resiliant to this than oil.

Basically the only thing holding them back is the culture of coruption in these countries (look at Venezuela for a example). If they can get things stable then sub sahara will be the super rich of the late 2000s and will leave saudi in the messy dust but sadly I am not optimistic. Corrupt countries seem to be very hard to reform. The sahara is the engergy source of the future but sadly politics and religion look like holding it back for many decades.

Re: Captain Pugwash theme was the best

Happy memories of tweaking BBC games to make them more convenient to load or to give infinite lives. There was a ROM called EXMON? Something like that and I disassembled everything!

OK now I am getting over enthusiastic - I have found the manual for EXMON, how can this still exist!

http://stardot.org.uk/mirrors/www.bbcdocs.com/filebase/software/apps/EXMONIImanual.pdf

I think it was Frak that had some more complicated mechanism with self modifying code - but 'patching' the game was at least as much fun as playing it.

I remember a bit of 6502 that I did to allow me to play games with to the limit RAM requirements despite the space lost for the disk drivers (that was floppy disk!). It intercepted the system calls and copied the relevant bit of game RAM to video until the floppy call was completed. Level 9 adventures - anyone remember them? The only one I completed was snowball but the resistor colour codes set me up for my future career. I was totally blown away when it played Vivaldi during the long long tape load times.

Re: Weird objects showing signs of being both Melty and Non-melty origin?

Rocks fall through the atmosphere far too quickly to melt. They come in at a minimum speed of 11 Km/s and usually much faster but the atmosphere is only a few 10s of Km thick, more if they come in at a glancing angle but even then they don't spend enough time in the atmosphere to get hot and certainly not enough time for the middle to even get warm.

Bowdlerization

This kind of thing has been done before. Thomas Bowdler produced versions of Shakespeare which fitted the morals of the time

Widely regarded as laughable and pointless a few generations later

Examples:

In Hamlet, the death of Ophelia was referred to as an accidental drowning, omitting the suggestions that she may have intended suicide.

"God!" as an exclamation is replaced with "Heavens!"

In Henry IV, Part 2, the prostitute Doll Tearsheet is omitted entirely; the slightly more reputable Mistress Quickly is retained.

I can easily see demands for exactly the same happening now.
