cipher_system | 1 year ago | on: Apple Watch Series 10

Check out The Quantified Scientists video Best Wearables for Sleep: Scientific Rankings.

He uses science test smart watches and Apple watches ranks at the top.

Maybe there are other brands that works better for you or maybe this is as good as it gets with just a watch and not a full sleep lab setup?

cipher_system | 3 years ago | on: Why high speed rail hasn’t caught on

At least where I live, the 150 minutes before time is a side effect of Covid. A lot of airport staff were let go and restaffing with security clearances takes a while.

This summer was exceptional, it will go back to normal like 60 minutes for domestic travel and maybe 90 minutes for international travel.

Break even, time wise, here is around 500 km and then train is the better choice. But there are a lot of destinations that can only be served realistically by airplanes and that is not likely to change much during my life time.

cipher_system | 4 years ago | on: Finland starts much-delayed nuclear plant, brings respite to power market

Last one was connected in 2009 which isn't that recent but there are also not that many projects of this size. China and Russia might not be the most thrustworthy and I would rather see more more western examples but then we have to go back a couple of decades, most of which were excellent.

I agree that a gigantic shift is required and put my hopes into mass produced SMRs. It's gonna take time and money, yes, just like the shift to EVs and renewables.

Fossil fuels is still above 80% of global primary energy, nuclear 5% and renewables excluding hydro 2%.

I really don't think putting all eggs in the solar/wind basket is good. They should of course also get heavy investments but that doesn't have to exclude nuclear. We're gonna need everything we have to end the fossil era.

I read a report on that a while back, can't find it now but these are the highlights I remember:

* The overall design must be done before construction starts, also no room for regulatory changes. Waterfall is better than Agile for nuclear.

* Experienced project management, work force and supply chain.

* Build many reactors on the same site and don't use a new reactor design.

* Work force is overall cheaper and possibly also more productive in Asia.

More or less the same as for everything else, the more you do it the better and cheaper it gets but it requires a lot of upfront costs.

Something like this. The project started in 2000, construction began in 2005 and should have been completed in 2010. Original cost was 3 billion euro but landed on over 10 billion euro.

It is the first nuclear reactor in Europe for 15 years so not much working experience or available sub contractors.

Apparently, China, South Korea, Japan and Russia can build at a third of the cost and time of that.

If nuclear energy should be considered, much more must be built more continuously.

Surely his approval ratings must have taken a massive hit?

The OMON, military and state media will also loose their life savings and suffer under the war and sanctions.

There's just so much protests they can handle and with more and more people with nothing left to loose, the momentum can quickly overwhelm them.

It's not gonna be easy but you're running out of options. Best of luck if you choose to fight.

cipher_system | 4 years ago | on: Russia Cannot Win The War

There was a military exercise with Sweden and Finland in that region at that time, they could have just wanted to have a little look and see and their signal recon from a distance probably sucks like everything else.

It's of course provocative but still less than 2013 when 4 fighter jets and 2 bombers flew in attack formation against Sweden in a simulated nuclear attack.

cipher_system | 4 years ago | on: Ask HN: Resources to Enter Darknet Markets?

Archetyp is a pretty new darknet market that seems solid and ships stuff from and to various places around the world.

You can find much better guides for this but these are the steps:

1. Download TOR Browser

2. Google the address to Archetyp, the url only works in TOR

3. Enter the site and create an account

4. Buy bitcoin or even better monero on for example localbitcoins

5. Transfer the coins to you electrum wallet

6. Transfer the coins from your electrum to the market place

7. Find the stuff you want to buy (best sourced from your country) and buy it to an address you choose.

edit: it struck me that this might not be allowed here, if so I apologise.

cipher_system | 4 years ago | on: AWS Tools Suck

Shouldn't a company of that size and revenue be able to do both at the same time?

I have absolutely no evidence to back this but I think they are actually making money of the bad tooling.

Firstly, because it requires and also creates an army of cloud AWS consultants that works as free sales persons for AWS.

Secondly, this army creates overly complicated and expensive solutions which then only they can change, and they never do because it looks good on CV.

Maybe a bit too cynical.

cipher_system | 4 years ago | on: Here’s How Many People Default on Their Student Loans in the U.S.

Almost everyone does it, but it's for living expenses, books and such, not for tuition.

Currently, a university student borrows around $800 and gets around $300 each month. Then you are supposed to pay back what you borrowed during 25 years starting 6 months after you stopped borrowing.

It really is a great system imho.

edit: Had to check, apparently only 70% takes student loans.

cipher_system | 4 years ago | on: Here’s How Many People Default on Their Student Loans in the U.S.

A lot of people have trouble paying their student loans and many seem to call for cancellation of all student debts.

The interest rates on US student loans are from around 5% according to https://www.valuepenguin.com/student-loans/student-loan-inte...

At the same time the US government can borrow at around 1%. Why not consider education an investment in society and let students borrow at this rate as well?

My swedish student loan has 0.05% interest rate this year.

I don't get it.
