POKE command

To set the record straight, POKE is a BASIC command and writes a byte of data into any memory location. If you POKE a number into the wrong part of memory you could crash the computer by corrupting part of a program. Remember the Sinclair ZX81?

Scrap removals.

Scrap handling is always down to cost. Recycling on the moon is a lovely ides, disposal in the sun is also a lovely idea. Problem is it costs too much. Its cheaper to dump it in a country lane and pay the fine.

Re: The Master of understatement

Thats a big area and it covers the area controlled by my local council, They are red hot on catching fly tippers. So much as one discarded cigarette end could catch a fine of £400 pounds. A pallet full of batteries deliberately dumped in a country lane would attract the maximum fine.

Bloat

Nobody needs all this preloaded bloat forced on by an upgrade. It should be available but not by default. I spend hours culling stuff forced on me every upgrade only for it come back a week later. I am not sure off the timing really but it is too often. I wonder if Microsoft is prepping us all for a miracle OS that is so efficient it will blow our minds.

Damn Small Linux returns after a 12-year gap

Small?

I had to double think here about the meaning of "damn small OS". Remember early systems? Just looking at Windows 3.1 requirements makes you wonder why we are so used to bloat that a 3.3G OS is called damn small. There is a real opportnity here for the development of a genuinly small OS with a friendly GUI and interfaces.

So, in twenty years time or later we will still see W10 or older being used in ATM and announcement board systems. I still fireup XP now and then just to remind me how fast a slow machine would run with a small OS. I also have DOS that runs serial ports on old machines. W10 or W11 wont do thar.

Millions of smart meters will brick it when 2G and 3G turns off

bernmeister

Re: Is it kVA or kW?

Interesting point nobody has picked up yet. Older meters ( the ones with the spinning disc) measured kWh ignoring the reactive content. Modern meters can charge for the reactive content of your consumption. Unless a smartmeter is replacing an older meter (does anybody still have one) there is probabbly nothing to worry about.

bernmeister

There is something (or everything) about smartmeters that does not ring true. They cant possibly save the billions clamed. Everybody knows if you keep your heating up high it will cost more. You dont need a smartmeter (or an Einstein) to tell you that. For the price of a fleet of UK aircraft carriers or nuclear submarines I am sure the money could have been better spent. An interesting point, I read somewhere a case where Einstein confused energy and power during an interview. It was a result of a colloquialism but I dont think he could be excused it.

Power backup

Power failure resilience is built in to telephone systems. Backup batteries are a standard part of system design. BT however have taken a backward step by starting to phase out copper telephone connection to the home and replace it with fibre. In the event of a power failure the BT service would contine but domestic routers would fail due to loss of power. BT propose to supply backup supplies to vulnerable users.(free or at a cost?). Sounds like a short term solution. A new breed of internet routers with high performance battteries built in are in order. Hang on a minute, I have got one in my pocke. I dont need that part of BT.

Tiny11 shrinks Windows 11 23H2 down to pocket size

bernmeister
WTF?

Opportunity to downsize

As MS continue to bloat Windows there are increasing opportunities to shrink it without any loss of functionility for most users. Every time I get an upgrade I have to spend days removing unwanted stuff. There are loads of unwanted things that are locked and I cant remove. Remember when you could run Windows 3 on a 300MB disk? People said "Why do you so much HD? You dont need that much". Yes, 300MB not 300GB. I can get down to 30GB for W10 but it soon creeps up.

Yes, but the phones have bigger, brighter displays, louder audio, bigger memories and loads of internal funtions. But as a phone they are pathetic. My Nokia 3000 is better at text and phone and still lasts all week on one charge with a battery the size of a matchbox and half as thick. (the battery, not the phone)

Backups that fail.

Backups that fail are a common problem in the industry. Backups get maintained but often not tested for fear that they will fail. Chernobyl disaster was reputed to be the result of a failed backup test. I personally crashed a system by switching over to an incorrectly set up backup. Luckily I was able to switch back after a few minutes. Nobody noticed except for the maintenance man and I. My boss never even knew about it. Whew!!

UK procurement is too glacial to bring AI into defense, MPs told

bernmeister

hang on a bit.

Its all very well saying that defence procurement procedures are too slow but equipment development can also be drawn out. How many defence contracts have had to be cancelled because the equipment became obsolete before delivery? I cant think of any examples off-hand but the history books are full of them. Perhaps BAE Systems Nimrod MRA4 is a prime example.

Re: Data-driven exercises like this demonstrate how AI can enhance our military capabilities

Mm, dont worry. In the case of AI lets hope the government keep their fingers out of the pie and just provide the money and some kind of ethical framework. When I was working on Skynet Remote Monitoring and Control (RMC) software, (yes, Skynet does exist but not in the form Arnie would recognize) we simply had the remit to make it work better than if a human was in control.There were n ethical remits, it was just fancy tracking software.

Re: Charger power rating

It would be more than a weekend even if the vehicles electronics took no current. Doing the calculation of USB-C power output to battery charge time with 100W USB-C supply, 98% efficient 5V to charging voltage converter (the efficiency may be much lower) and 400kWh batery pack, the charge time would be about 6 months. Dont try this at home folks. I think I have the calculations right.

Europe's right-to-repair law asks hardware makers for fixes for up to 10 years

Its because the Apple leads are sleeved with silicone rubber. Its much chewier than PVC and over time the handled parts absorb natural oils making them even more attractive to chew. Thats my theory. Any advances on that?

The loophhole will be bigger than that. Many critical parts are manufactured on a limited time run. After a few years parts become unavailble, even to the equipment manufacturer. I was given the job of locating parts to support 10 years of repair of a unit on the verge of being phased out.Critical control chips etc were discontinued years previously. Result, no 10 year support.

Digital transformation expert on mass layoffs: I would have expected more from tech

bernmeister

Blind leading the blind?

Layoffs are often higher management policy decisions made with no respect to project requirements. Afterall, a detailed analysis of who is needed or not would take time and money to carry out. When I was made redundant together with my customer support team, my group manager was not consulted nor were my customers, internal and external. The team were given one months pay in lieu of notice, statutory redundancy payment, unused holiday pay and an additional £3,000 if we signed a non disclosure agreement. I have no Idea what happened to my customers. I know some complained to the managing director but micro-managing redundancies was obviously not on the cards.

When it comes to liquid and immersion cooling, Nvidia asks: Why not both?

bernmeister
Pint

Cashcoin Liquid

I was involved in helping a cryptocurrency mining company setup liquid cooling for their server PSUs. They had a relatively simple solution where the PSU racks were immersed in dielectric fluid. Fans had to be removed and heatsink paste cleaned off before immersion. Certain components also needed to be replaced with immersion compatible types. The modifications were small and well within the capabilities of the customer. The result was successful.

Making other parts of the system compatible with liquid immersion was not attempted. I dont think anybody had the nerve to dump a working server into a tank of coolant. Perhaps with SSDs in the servers they may get that far. They werent spending millions on R&D, they were making millions. The mine was setup right next to a hydroelectric source to keep power costs down.They had a lot in their favour.

That old box of tech junk you should probably throw out saves a warehouse

Older PSUs

If you are a real hoarder 5V 2A PSUs should form a layer at the bottom of your odds and ends drawer. Many routers from the late 20th century used 5V external PSUs. Keep the old routers as well, you never know when they will be handy.

Techies try to bypass damaged UPS, send 380V into air traffic system

bernmeister
Alert

"Fried" is a colloquialism used to describe damaged electronics. Dont take it too literally. It doesnt take many Watts at high voltage in the wrong place to wreck electronics. Fuses are not intended to protect electronics from failure, their main purpose is to pevent fire in equipment. Even surge arrestors may not prevent damage. Protecting against the kind of overvoltage experienced would require circuits specifically designed for that purpose. Either they did not exist or had been bypassed.

bernmeister

Start of a trend.

Just recently there has been a rash of failures in airport communication systems. A chronological list is needed. This failure has been closely followed by an unrelated failure in the USA, closing down all USA commercial airspace. Who's next? Systems have neen critcized as being old fashioned and out of date but with design and implemention times of years parts can become obsolete before the system is up and running.

FAA grounds all US departures after NOTAM goes down

Thumb Up

Simple system

NOTAM was a relatively simple system using Baudot code on RTTY. I wonder what they have done to it to make it crash? I was working on a system in South America intended to get NOTAM's onto the satellite REDDIG system designed to connect all South American airports. I freaked out when an airport NOTAM system crashed so I reverted it back to original configuration. The system designers stepped in and made it work. The loss of service was so short nobodty noticed.

As liquid cooling takes off in the datacenter, fortune favors the brave

bernmeister

Horses for Circuits

Immersion coolant can take many forms. I have experience of immersion cooling of PSU,s. Very successful, just remove the fans, wash off heat sink compound and dump the supplies in coolant. Not really that simple but thats the principal. Some components are not compatible with the coolant, they need replacing with a different type. Eventually an extremely effective system was the result. The supplies were used to power bit-coin mining systems so cost effectiveness was essential.

Study suggests AI cruise control could kill traffic jams by cutting out the 'intuition' factor

Re: Reaction Time.

As an afterthought, AI wont solve traffic problems unlss the traffic is 100% AI controlled. It just takes one dozy human driver to screewup the flow.

bernmeister

Reaction Time.

You dont need AI to keep traffic flowing you need a man with white gloves and a whistle. Seriously though, why is it that when the lights turn to green nobody moves? Many is the time I have pulled away at the green light only to find that the car in front is not moving. End result is only three cars through the lights and traffic bunching.

Voice assistants failed because they serve their makers more than they help users

The whole idea of the voice assistant is flawed. A simple text search of the internet is all that is needed. Voice recognition and AI turn a simple request into a case of Chinese whispers. "Send me two and sixpence I am going to a dance" could turn into the start of a war.
