The 1900/1910 MHz block is reserved for railway communications in Malaysia (and other countries I believe) - a safety critical usage, so interference from satellites would be a serious issue.

A lot of the cost of backup is the security guards you need to stop your batteries being stolen. This is a cost that doesn't go up as you add more batteries

Fingerprints are not compared as images. There are several proprietary and incompatible systems that classify what are considered as important details of a print. This data reduction greatly increases the probability of false positives.

5G is working fine in urban parts of Malaysia now. It does drain your phone battery faster.

So far the telcos have been unable to charge the premium price they were hoping for and my monthly data cap is an order of magnitude higher than my usage.

The IOT hype for 5G has not worked out at all and I cannot see 6G helping.

To me 6G is really about patent control and excluding China.

Remember PLANET?

Before Token Ring, RACAL had its PLANET dual rotating ring "LAN". This staerted life as a method of networking RS232, PC connection was added in the mid 80s.

This one failed to get the IEEE blessing.

A lot of what we now are familiar with in Ethernet was borrowed from AT&T Starlan, which was a 1 Mbps tree and branch

There are many "real authors" who have done nothing more than rehash existing stories without an original idea over the years.

This is what the AI basically does

I checked and found an unexpected security update for my A53G, the last only on 6th March, so maybe connected

This is about immortality really

The SciFi dream is of moving the mind out of the biological brain

56 Cores

So only useful for massively threaded applications then

Congestion

So Kuiper is just above the Starlink orbit and they in turn are just above Hubble, the ISS a bit lower.

Any launch failures and you will risk collisions

PABXs

There are still plenty of analog telephony PABXs out there with 2 Mbps trunk lines.

I had trouble buying a fixed line telephone recently to replace a broken set which was on my VOIP gateway box at home.

Looks like someone chose hydrogen without thinking about its abysmal energy density. Those high pressure tanks are heavy

Politics too

Any cable from Australia to Singapore inevitably passes through Indonesian territorial waters..

The North Sea cables don't have these 3rd party problems

Packaging and test requires cheap labour, which is why Malaysia and the Philippines have so much.

Italy is an unsuitable candidate for the fabs as it is prone to earthquakes and the odd volcano, plus short of water

Asimovs Foundation series

If you remember, in the Foundation series the "Engineers" had become a cult trying to maintain a technology that they did not understand.

The West is well down the road in following that as a script.

I was surprised to see a TikTok app installed during a clean Windows10 install.recently

Nationality again?

Softbank is Japanese and the US courts have plenty of track record in favouring US companies in patent cases

But still most ICs are out of stock at the distributors

A lot of pressure for 6G is because China has a lot of the 5G patents and certain countries want to shut China out.

Already where I am there is a single 5G infrastructure operator as its simply crazy economics to have every telco with its own physical base station in every street.

I wonder how many others are less stupid and don't get recorded and caught

There is something wrong with a price model that doesn't cover electricity and cooling costs. If you do that, coin mining is hopelessly uneconomic on a general purpose CPU

Never try to cheat the tax man, it doesn't end well unless you are a billionaire

Some backstory here

TLDR - not all cables are suitable for 600W

Which state is better in the USA?

There are downsides to many states. Some have earthquakes, some hurricanes, some no staff, some too expensive staff

Product lifecycle?

The question with this class of SBC is how long will you be able to buy it for after you have designed it into some system

Realistic rates

In Malaysia you can get a fresh graduate for $6000pa

A competent software developer who can write a spec and follow it and test will cost you far more, from $25000pa, but still much less than in the West

A bag of sand launched into reverse orbit would be a very simple and effective method, a fairly long time before all the debris de-orbits though

I find Google shows roads as uncongested when they are actually gridlocked because so many motorcycle delivery riders are weaving through.

The fundamental error is not differentiating the App users into cars and bikes

This is average lead time, so lead times in years is all too common

Maybe I might be able to buy a Radeon graphics card again
