Apart from the Yuck factor these drinks may not legally be called "Beer", at least in civilised countries.

Happy 60th, Sinclair Radionics: We'll remember you for your revolutionary calculators and crap watches

davcefai

Nostalgia

At school in 1964 I helped the science teacher to build a stereo system around a BBC studio Tape Deck and a Sinclair set of apmlifier, preamp and speakers.

The sound from the Sinclair kit was, for those days, astounding. The Rector suspected that we had spent well over our budget!

When I got to Edinburgh in 1973 the first thing I bought was a Sinclair Cambridge calculator. They were so new that at examination time the Heriot Watt University Senate ruled that while Slide Rules were OK we could not use calculators in our exams as they would give their owners an unfair advantage. Only 2 out of 14 in the course owned a calculator.

Systemd 249 release candidate includes better support for immutable OSes and provisioning images

Re: Thinks I like about systemd

Just change the patch cable.

And dump Systemd while you're at it.

I never had to tinker with my systems as mush as I had to in the 3 months before I first reverted to init and then moved to Devuan.

Systemd makes MS Windows look good!

I would consider that refusal to be vaccinated constitutes "reckless endangerment" to others and there are already mechanisms for coping with this.

There is compulsory vaccination for children.

So come down on these refusniks with the full force of the law and make the world safer for sensible people.

Someone tried to poison a Florida city by hijacking its water treatment plant via TeamViewer, says sheriff

Strangely, the hack is described in terms of ppm of Caustic Soda. Dosing is usually via a dosing pump (variable speed and stroke) and would be set by adjusting a pH target. It is not possible to dose Caustic Soda directly - it consists of very hygroscopic pearls or flakes.

It is probably possible to set up such a system to work with ppm, by calculating ppm from the water flow rare and the dosig rate but who on earth would bother? !!

In any sanely engineered system you would set the target pH ( usually 7.4 to 7.8) and let the pump and pH meter sort things out. That's maybe 10 lines of code. Then you add another 100 or so to cope with all the error conditions you can think up but essentially if pH drops below 7 or rises above 8 the plant should stop and raise an alarm. The operator should not be able to set insane dosing values.

I've done, or had done for me, several such mini plants dosing caustic, acid or sodium hypochlorite.

Forget the plant security, Windows or Team Viewer. The adjustment should simply not have been possible.

Not going Huawei just yet: UK ministers reportedly rethinking pledge to kick Chinese firm out of telco networks by 2023

davcefai

Re: shambles.gov.uk/2020-05-27#huawei

This reminds me of the Falklands war. The UK did not have a suitable rocket so it bought Exocets from France. (I think there may have been British investment there too). The Argentinians also bought Exocets. Some people made/saved lots of money by "outsourcing" vital industries. Others were killed by the consequences.

At least at the moment we can choose Chinese or American kit. The Americans can probably not compete on the current playing field want want to be sole suppliers to the world.

I used to _love_ sending emails "Please resend in a more acceptable format" to a company that adopted every new iteration of MS Office the day it was released.

Our company was, OTOH, very slow at adopting the new versions.

It can get worse!

Malta has a growing anti-5G movement. Big to-do with photos of new masts. The sad thing is:

1. There are no 5G masts yet in Malta.

2. None of the providers have even applied for a licence yet.

Never underestimate the power of stupidity. Remember that "MRI" was initially called "NMR" - Nuclear Magnetic Resonance- but people were frightened of the "Nuclear" bit.

Re: Finally!

Did you still need an incentive? When systemd was released on us, I felt that I was back in the Windows days! And it looks like it can only get worse. Why can't Poettering go away and write his own OS, leaving us to the stability we worked so hard to achieve?

Linux 5.3 kernel bundles new, cuddlier, swear-free Torvalds with AMD Radeon Navi graphics support

Re: OMFG

I remember when he was foisting pulseaudio on us. His standard reply to bug reports was that it would get better soon. Frankly I cannot understand how Poettering has been allowed to screw up Linux with systemd. It goes against the basic philosophy of ONE tool doing ONE thing very well.

Which is why I dropped Debian for Devuan.

Lusers

Lusers are lusers everywhere. A few years ago we were building a new production facility. When it came to cladding the front we had to close off the road leading to the Marketing Dept. So we assigned new parking spaces, dotted the area with "Keep Out" posters and we posted maps and instructions on how to walk to Marketing via a different route

Next day 4 girls from Marketing - cookie cut types with long straight hair and sub-par IQs - came to complain that they had torn their tights climbing over the barriers in the road.

'Bulls%^t! Complete bull$h*t!' Reset the clock on the last time woke Linus Torvalds exploded at a Linux kernel dev

Thumb Up

Linus is the man who keeps the project going. A brilliant coder but also a brilliant cat-herder. What other OS progressed as fast and as well as Linux?

So he gets pissed off at some people. So what? His system(s) work and the OS keeps going strong.

Linus doesn't need to write code. He does need to manage it. And he does, in a way most managers can envy.

Mr Torvalds, in case you get to read this, consider your hand shaken.

However I confess to feeling uneasy about when he retires. OTOH I'm much older than he is so I'll be past caring. I just hope that Poettering doesn't complete the job of destroying Linux.

It may be poor man's Photoshop, but GIMP casts a Long Shadow with latest update

Re: Forget the geeky stuff, sort out the user experience.

The UI used to be "one of a kind" where you could spend more time looking for a function than using it. The default UI is now much more conventional. Frankly I was not aware that there is another one and will spend some time trying to find it.

After PSP went past v9 GIMP became my default photo app, especially as I could then use it on both Windows (at work) and Linux (at home).

Re: Great Headline, Register

The short story was first. The book you describe is "The Lost Worlds of 2001". As far as I remember the screenplay and book were written together. Certainly the film is very faithful to the book.

And we return to Munich's migration back to Windows – it's going to cost what now?! €100m!

There is also a non-technical reason for this retrogressive step. One that I have experienced myself.

Some people consider themselves too important to use "free" (=, in their minds, "cheap") software.

Because of this what was going to be a well managed transition from MS Office to OpenOffice, with Sun's assistance, ended up in disaster. Incidentally, unless things have changed a lot since I retired, it is NOT feasible to run MS Office and Open or Libre Office together for any long time.

HMS Queen Elizabeth has sprung a leak and everyone's all a-tizzy

I've just looked at a link to the Sun. Sad to think how many trees died to supply this drivel.

davcefai

Seals leak. Fact of life. Usually tightening (compressing the packing further) helps. Otherwise replace the packing. Big deal. The really bad case would be a roughness in the shaft - it would need re-machining. *That* would justify the fuss being made. I've had expert craftsmen have problems in getting packing exactly right and this was on shafts maybe 3" dia max.

Packing starts to leak *after* some use. That's probably one of the reasons the navy do sea trials. :-)

I can't call this a storm in a teacup because the ship is too big to fit in a teacup.

Buillied

One day, one hopes, the UK will stop being bullied by the US. (I am not a national of either country).

As I understand it the law about extraditions works in favour of the US. The Brits cannot get _their_ naughty boys back from the US.

Love is English, sat at his computer in England and was arrested in England. So if guilty he is guilty of an offence in England, not the land of the cholesterol-laden fast foods. Do we even know that the computers he hacked are physically located in the US?

Linus Torvalds 'sorry' for swearing, blames popularity of Linux itself

davcefai

All is well, really.

Linus pioneered not only a new OS but also new ways of developing and distributing it.

"release early and often" was the mantra in the good old days. Users found the bugs and they were fixed - very quickly. If someone cannot cope with this they should wait to upgrade until other hardier souls, or people not running mission critical systems, found the bugs.

Linux has been a dynamic and vigorous ecosystem. Linus found exactly the right formula to manage it. If the genes that made this possible are linked to others like sweariness then "ce la vie". Deal with it. Don't try to put ridiculous code into the system, and just grin and say sorry if you inadvertently do so.

Which makes one wonder how in hell we got stuck with pulseaudio and systemd! :-)
