Title: Tech News
Post by: Wooster on April 07, 2019, 08:01:07 PM
According to New Scientist, mathematicians have found a new way of adding two integers together that is faster than the method currently employed.

Using the common algorithm of sticking one number over the other then multiplying the individual digits, it would take a computer six months to multiply two billion digit long numbers, so they found better algorithms that used logarithms to shorten the process.
The new method has shortened the process even more, but there's a wee bit of a drawback, it currently only works on numbers that are more than 20 trillion trillion trillion digits (that's a 20 with 36 zeros after it) long. :cheesy:
Still, there are bound to be some applications that use numbers that big (climate modelling?)

Electric cars emit more CO2 than diesel. Well we all guessed this electric car thing was a scam.

Germany use a lot of brown coal (Lignite?) in their electricity production though.

They do, but presumably that's taken into account. Do we have any coal-fired stations left? I'm not sure, and we've had more than a few days this year when renewables have powered the entire UK for days at a time. We have the biggest offshore windfarms in Europe. I'm not sure where we lie in world rankings.

Of course wind turbines are extremely expensive to make in terms of manufacture, maintenance and the materials themselves.

Apparently they take about 8 months to offset their manufacturing carbon costs.

CXL Compute eXpress Link, is a new standard for connecting high-speed CPU-to-Device and CPU-to-Memory, and is backward compatible with PCIE cards, which is good

Toshiba announces new non volatile memory, and it will already mark the end of the NVME drives. How quickly tech moves these days

Windows security holes found, but patched at the last update.....not really a surprise given the amount of backdoor holes they've created for the NSA

Nvidia have said they're going to throttle the amount of cryto-mining abilities
https://www.bbc.co.uk/news/technology-56114508

If true, about time. Global shortage of silicon due to the pandemic and the huge co2 footprint these cryto-farms produce is quite staggering

It's already useless.

A cryptocrippled 3060 can still earn $7 in ethereum in a day which is still high enough for cryptofarmers to consider buying in bulk.

Card prices are a bit crazy across the board, if you can get one.

I was having a wee browse on Scan last week and they don't have many.

I was lucky to get my hands on a new Asus Rog Strix Rx5700XT down here about six weeks ago. No more left and used ones are triple the price I paid, which was less than $500.

I could sell me 3070 for £300 (+) more than I paid for it.
