doikor··on Effectiveness of an walking intervention for the prevention of low back pain
For me it was squat and deadlift with a lot of stretching.

Though for me a lot of the lower back pain came from really tight hamstrings so the stretching was important for that (and you can't really do squats and deadlifts with proper form without enough flexibility)

doikor··on Java string interpolation feature has been cancelled
It's strange as they point out that doing what Scala does is not possible as the language already has string literals that could contain the $ syntax stuff. But Scala does not enable string interpolation without explicitly using it by adding s infront of the string (s"some $value ${another}way")

Though as they point out the syntax was not really the problem.

doikor··on Japan enacts law to promote competition in smartphone app stores
> But according to Epic, why...if Epic can make its own app store for iOS, consumers will benefit! Bullshit. All that will happen is we'll have to install multiple app store apps on our phones, having each one collect data constantly about us...

Most of Epics arguments are that the developer will benefit by them taking a smaller cut then Apple/Google/Steam/etc so if they sell the game for the same price the developer gets to keep a couple percentage points more money.

I don't remember any argument they have made that has put the customer as the beneficiary though there probably are some.

doikor··on Japan enacts law to promote competition in smartphone app stores
> and the store will be slow and shitty and packed with ads.v

But both Apple and Googles stores are slow and packed with ads. Pretty much every search you do for an app even with the exact name gives you some ad supported shovelware as the first one or two results (ads).

So how is this meaningfully any worse? (outside of one more login you might need to setup).

But the apps by Apple and Google can do that. Why do you want their Apps to be able todo that and not others?
doikor··on AMD Unveils Ryzen 9000 CPUs for Desktop, Zen 5
The GPU in the APU is on a totally different level when compared to the 2 core RDNA 2 one in the “normal” CPUs

For example the 780m you mentioned has 12 cores and newer architecture so is probably something like 10 to 15 times more powerful.

doikor··on AMD Unveils Ryzen 9000 CPUs for Desktop, Zen 5
> The CPUs are also using the previous-gen graphics architecture, RDNA2.

The GPU on these parts is there mostly for being able to boot into BIOS or OS for debugging. Basically when things go wrong and you want to debug what is broken (remove GPU from machine and see if things work)

doikor··on MSI Teases Z790 Project Zero Plus Motherboard with CAMM2 Memory Support
It's not really a vendor thing but signal integrity issue.

CAMM2 just makes a lot more sense with DDR5. And fact is that we most likely want our next standard to be even faster so the issue is just going to get worse with DDR6 or whatever the next one we are going for is.

doikor··on MSI Teases Z790 Project Zero Plus Motherboard with CAMM2 Memory Support
You just buy large modules. There are 64 and 128gb modules (mainly meant for servers)

For example 64gb from Samsung for 350€ https://www.dateks.lv/en/cenas/atmina-ram/1028642-samsung-64...

I think they go up to 512gb per single module these days. The really big ones are really hard to buy for us mere mortals but you can get them through various data center/enterprise hardware vendors.

With DDR5 it is very unlikely that you are going to add more memory modules on consumer boards. This is because if you add more then 2 you half the speed on both AMD and Intel platforms (and you don't get full speed with just 1 stick). Also if the new module is not exactly the same as the previous ones you can very easily run into stability issues.

This is why on consumer land you are pretty much always buying your memory as a kit (of 2 modules with DDR5). And if you want more you buy a bigger kit and sell your old ones or throw them in the trash.

On server side the memory controller on the CPU is much more beefy and the motherboard better built to allow for more memory sticks to run at full speeds. But even then you usually have to go and find memory that the OEM qualified/teste for you.

doikor··on What the damaged Svalbard cable looked like
They can just not really worth the hassle/money. You can pull the cable up and change them out if you want.

Pulling a cable up, cutting a damaged part out of it and putting a new piece in is done all the time to fix damaged cables.

doikor··on Cement recycling method could help solve one of the big climate challenges
Arc furnaces are also expensive so realistically you want to have one running as close to 24/7 as possible.
doikor··on Windows 10 wallpaper was physically built and photographed (2015)
It doesn't look as good and Blender/3d modeling software in general have come a long way in the last 9 years or so (Windows 10 came out in 2015)

Sure it could can/could be done but it would take a lot of time to get as good a result. Probably easier to just photograph it for real and photoshop a little bit.

doikor··on Microsoft Paint's new AI image generator builds on your brushstrokes
No they dictate what their program (Paint) can generate. Nobody is forcing you to use it.
doikor··on Boeing faces new US investigation into 'missed' 787 inspections
The owners/economy has demanded for things to become more efficient then last year every year for decades now.

If no massive technological breakthrough happens at some point the operation is as efficient as it can be while producing safe products but still you have to become more efficient for next quarterly/yearly results to keep the shareholders happy (if you can't find new clients to expand to). It is at that point that you start cutting corners and end up in situations like this.

This happens in every field but obviously in most fields the cost of these failures is not big enough to really matter but when you apply it to aviation you get planes with hundreds of people crashing into the ocean.

If you count the leaks then the numbers are not that good.
doikor··on JEDEC Extends DDR5 Memory Spec to 8800 MT/S, Adds Anti-Rowhammer Features
PRAC should happen automatically in the background when possible and when it really needs to stop the controller from accessing something while waiting for the bits to refresh it uses the already existing ALERTn signal.

https://stefan.t8k2.com/rh/PRAC/index.html

> Panopticon retrofits an existing signal in the DDR specification, called ALERTn, to effectively “trick” the memory controller to pause issuing new DDR commands. DRAM uses ALERTn to signal errors to the memory controller. Upon receiving this signal, the memory controller stops issuing new DRAM commands and instead re-issues the old memory access. By making use of ALERTn, Panopticon requires no modifications to any hardware other than DRAM itself.

(As I understand PRAC uses the same design as Panopticon for this part)

doikor··on Spotify demonetizes all tracks under 1k streams
Yea there are better ways to fix the problem but the problem is selling that fix to the big labels. The current system gets them a larger share of the revenue so why would they be interested in changing it?
doikor··on Autonomous Overhead Powerline Recharging for Uninterrupted Drone Operations [video]
That is going to be really hard (impossible?) to monitor for billing purposes. Basically would have to resort to self reporting/honor system.
doikor··on Eight U.S. States Now Have Plans to Ban Sales of Gas-Powered Cars
Gas and diesel have relatively short shelf lives.

They last around 12 months (way less for gas with added ethanol) if stored properly meaning not too cold or hot and no big temperature changes.

This can be extended with preservatives/stabilizers to a few years but after that you are fucked if you don’t run a refinery.

So yeah preppers should go with electric. Batteries also have a limited lifespan but it should be longer if managed properly.

doikor··on Group buys up large tracts of land in Romania to create 'European Yellowstone'
I guess it depends if land marked as a natural park is tax exempt or not (don't know about Romania legislation on this). If not then they need some revenue to cover the taxes.

Not a lot of states are willing to put too much of their land outside of the economy (tax revenue).

doikor··on Julian Assange granted permission to appeal against extradition to US
Important part is that it is the countries spying in each other not private individuals.

This gives the spy protection as both sides are spying on each other so usually what happens is some snarky comment/strongly worded letter and expulsion of a few spies back to their home country from both sides.

In the worst case someone goes to prison but usually in response the other side also finds some spies to put into prison too as "revenge".

Also whatever information the spies manage to get in general is not released to the public.

doikor··on Icelandic Approved Names – Nordic Names
Here in Finland there is no list but if you try to give a name that has not been given before it goes to a board to be checked that it is appropriate.

Basically done to protect the child from names that they would be bullied for.

doikor··on Financial systems take a holiday
> Instant money transfer means instantly draining someone's bank account with no recourse. Checks have plenty of opportunities to stop the money, so you can write a check on a Sunday as easily as a Wednesday. Wires are more irreversible and so you can only send those when the bank is open and there's someone to double check any suspicious behavior.

We have instant 24/7 money transfer in EU/Eurozone using SEPA Instant Credit Transfer (well technically it has "up to 10 second" delay) and it hasn't really been an issue.

doikor··on Solar and battery to make up 81% of new US electric-generating capacity in 2024
The operators have been paying into a fund since the 80s which is meant for decommissioning and spent fuel storage.

Basically it is a legal requirement (some small fraction of a cent for every kWh produiced)

This is really the only sane way to do it.

Also we got lucky with the ground under Olkiluoto being good spot for nuclear waste storage so not much NIMBY stuff for that as it is already the site for the biggest nuclear power plant in the country. It is also small town so a huge % of the population there work at the plant or its sub contractors.

doikor··on Solar and battery to make up 81% of new US electric-generating capacity in 2024
I would say cherry-picking data points is better then providing 0 data points.

edit:

Basically competent operators hit ~90%.

US is around 93%.

Sweden 84%

Switzerland 90%

France would hit that if they could run their plants at 100% when they are on but they run theirs in load following mode due to having so many of them. So they run at around 80%.

World average is 83%.

And yes I know best the numbers about the market I live in because I live here and this stuff effects the price I have to pay for electricity.

doikor··on Solar and battery to make up 81% of new US electric-generating capacity in 2024
Don't know about France but TVO in Finland is way under that. Their earlier reactors were built in the 70s.

They have been hitting 15 to 20€/MWh for decades now. Or at least this is the price they have been selling to their owners without going bankrupt for decades now. Target with OL3 in the mix is 40€/MWh so OL3 alone is probably in the 50€/MWh to 60€/MWh range. (and they got a really good deal with OL3)

doikor··on Solar and battery to make up 81% of new US electric-generating capacity in 2024
Refueling and maintenance are the "normal" things and both are planned to the time of year with least consumption/lowest electricity prices.

Then you have the rare non planned outages but once a new reactor has been running for a year or two and all the kinks have been worked out they should be very rare.

doikor··on Solar and battery to make up 81% of new US electric-generating capacity in 2024
Only if the operator is criminally incompetent.

90%+ capacity factor/uptime is pretty much standard and the better ones reach ~95%

For example TVO in Finland has 93% to 97% depending on the reactor since the early 1990s. Fortum has very similar numbers for their reactors.
