2rsf··on Ask HN: What companies have blown you away with their customer support?
Nice, the Swedish tax authorities are usually like that- very helpful, quick to answer and do their best to solve your problem.
2rsf··on Using a 4g/5g router? This phone setting could save you a few quid
Same for Windows, it is called "Metered Connection"
2rsf··on Do Anyone Know the Role of AI in DevOps?
Anomaly detection based on telemetry
2rsf··on Ask HN: Best no/low-code QA automation tool
Until a few years ago there was nothing ready out of the box and we had to build a solution ourselves. All the building blocks are available but you'll need to integrate them yourself.
2rsf··on NASA just sent a software update to a spacecraft 12B miles away
Assembly software, Launched in 1977 with link speed of a few hundred bps
2rsf··on Sweden reports damage to Baltic Sea cable with Estonia
Define "ensure", you can easily damage any cable undersea or not and if anything under sea ones are harder to get to.
2rsf··on A three-state solution is the only viable future for Israel and the Palestinians
The problem is again that the three sides are not willing to compromise,

Gaza was returned to the Palestinians in 2005 with no pre conditions, the Israeli settlements were left as-is in hope that Palestinians will use it for good. The famous blocked came only a couple of years later when Hamas won the election.

The Palestinian Authority is not recognized as a state for still have embassies in some countries, so at least for a short while there were 3 states but all in a very unstable and fragile state.

Hamas never abandoned the will the eliminate Israel, extremist Israelis never abandoned the will the add more and more settlements without bothering finding a solution to Arabs, the PA is also not trying to find a real solution partly due to corruption and being afraid of their own rivals.

Having lived most of my adult life in the area I can see how everyone have apoint (with a strong exception of extremists and especially Hamas) but on the other hand how a compromise will never be reached.

2rsf··on Internet traffic in Israel surged 170% right after the Hamas attack
According to a podcast I recently listened to this is not entirely accurate. Herzl did consider Uganda, but not too seriously and it is assumed that he used it to raise support for the idea of a national jewish home and not to actually go there.
2rsf··on Ask HN: Moving from Sweden to the Bay Area
WHy?
2rsf··on Ask HN: Moving from Sweden to the Bay Area
> Another route could be working for a European consulting firm or a Swedish company with an office in SF, then move to the US via them. Good luck!

Or an American company like Microsoft, Google or Apple. Those have some development done in Sweden, but you can get employed anywhere in the EU much easier than in the US, at least Visa wise, or take technical support roles and move on later to the US.

2rsf··on Ask HN: Does your microwave interfere with Bluetooth? Mine does
But the rabbit hole goes further. Higher frequencies are more susceptible to wall in the middle problems, you can see that easily with 5GHz WiFi, lower frequencies might be better but require larger antennas and might suffer from other limitations. As everything else in engineering this is a compromise.
2rsf··on Ways to break your systems code using volatile (2010)
As a former embedded engineer on older Motorola and ARM processors I have seen reordering happening, and more than once had to check the generated assembly code, the other items more or less makes sense if you don't expect too much from your compiler, for example using volatile to get atomicity.

Using volatile on multi-threaded code is ok as long as you know what you are doing, for example kicking a watchdog at a defined physical address could be fine from different threads.

2rsf··on Ask HN: What software do you need, that doesn't exist?
My Polestar won't let me lock the car if the phone is left inside
2rsf··on Ask HN: Why are some companies still trying to force return to office?
> the consensus is that you can do just fine

Consensus where? many managers quote the Microsoft study that Remote work is making productivity and innovation harder for example

2rsf··on Pictures from an unshared note can leak into shared notes on iOS
Can you reproduce it when the next note is shared?
2rsf··on Ask HN: Should pay be based on Performance Reviews?
There is no simple answer. Companies like Microsoft prove that a simple performance to pay to promotions mapping doesn't work well, is easy to game and can lead to frustration. This is especially true for large companies that try to keep everything leveled across the company.

On the other hand signoring performance altogether can lead to laziness, and doing the bare minimum at your work.

Many places choose some middle way, but that leads to other problems like unfairness and involving luck in your promotion or salary.

2rsf··on Ask HN: Should pay be based on Performance Reviews?
> Standardized pay, like at universities and the military, has a positive correlation to retention

How does it correlate with quality? retention comes from being comfortable to be.. lazy- you can do the minimum not to get fired and still get paid.

2rsf··on How do people qualitatively measure their developer experience?
But also not directly to developer's experience. Try the SPACE framework [1] from the same people, Nicole Forsgren et al. It is more of a survey than measurable objective metrics, and the problem is with the implementation, like any other survey- build good questions, operating the survey analysis and results etc.

There some comercial tools available, for example getdx [2]

2rsf··on Ask HN: Who is hiring? (October 2023)
That's 30 European vacations days before public holidays, so closer to 40, and more important is that you are expected to actually use them with no eyebrows raised
2rsf··on Burning money on paid ads for a dev tool – what we've learned
And surprisingly there are real people giving more than decent answers in Quora on things ranging from relationships through electric cars to software engineering.

Who are those people is a good question, as I never met or heard of someone answering in Quora, and it is rare to see links to answers in it.

2rsf··on The German group buying ticket dodgers out of prison
The Swedish planka.nu establish in 2001 collect money from members with the goal to pay fines for people evading paying subway fares, mostly as a way to protest against the raising prices.
2rsf··on Final Reminder: Send to Kindle Will No Longer Support MOBI File Formats
They have been sending those for a while, usually it's not a big issue as you can find or convert files in most formats.
2rsf··on Ask HN: Why don't more middle-class Americans emigrate to Europe?
From anecdotal cases here in Sweden I can say that adjusting to a more "socialist" way of life is not always easy. Few American colleagues, all young healthy and unmarried, left after a few years because they couldn't handle the high taxes and more expensive prices.

But as other have mentioned this is a very theoretical question. A software engineer will do just fine, like I did, while a restaurant worker might find it harder.

2rsf··on The SR-71 Blackbird Astro-Nav System worked by tracking the stars
Based on pictures the CEP should be very small, centimeters maybe. This missile doesn't explode, instead it send 6 blades at the target. Pictures show direct hits.
2rsf··on The SR-71 Blackbird Astro-Nav System worked by tracking the stars
That's for Inertial Navigation Systems, they measure acceleration and from that integrate your position.
2rsf··on The SR-71 Blackbird Astro-Nav System worked by tracking the stars
And even they make mistakes, software contains much more moving parts than hardware.

2rsf··on The SR-71 Blackbird Astro-Nav System worked by tracking the stars
> For reasons I still can't fathom, a contractor for the Israeli military purchased many copies

The Arrow 3 missile uses a star tracker, maybe previous generations or other missiles used those as well.

2rsf··on Bitwarden: Free, open-source password manager
I agree with the first part of your statement, but how do you access an encrypted keepass file from mobiles?
2rsf··on Ask HN: Is cell phone radiation still a concern in 2023?
It also has simple power control, making sure that all phones are received at the same power on the receiving antenna. Overall OFDMA is magic, if you can put your hands on a spectrum analyzer with constellation diagram you will be amazed.
2rsf··on Ask HN: Is cell phone radiation still a concern in 2023?
TDMA is long gone, and there are no "edges of packets" as you imagine them. I am not an expert, I only have little experience and knowledge from working in the area, but for example a few symbols are transmitted together using carriers at different phases. Those audio noises used to exist in the GSM area but no longer in 3G and 4G.
