2rsf··on Ask HN: Electricity Rate Arbitrage?
What's in it for you as an individual? With electricity prices ranging 25 - 50 ¢/kWh (random number from Google, but I guess it is close enough) and a battery of 500kW (6-7 old Tesla batteries maybe?) you will get up to a whopping 125$ per day , probably much less due to delivery costs. On the other hand such an installation will require a lot of real estate and the solar panels/wind turbines will cost a small fortune.
2rsf··on Wi-Fi radio signal data can be used 'to predict passwords'
Those kinds of articles make spy movies seem as old and outdated, and this is only the available public information.
2rsf··on Credit card debt collection
Swedish credit cards work with invoices and you are able to pay in partial payments, overdraft doesn't exist
2rsf··on Ask HN: Which iPad would you buy for reading technical books in 2023?
9th generation iPad, it is cheap and more than adequate for the job. It is still being sold so support is guaranteed for a while and has everything you need and much more.
2rsf··on Credit card debt collection
In Sweden you can apply for a credit card directly through the bank. And aren't credit card companies separated from the bank everywhere?
2rsf··on Credit card debt collection
with credit cards =/= using the card regularly
2rsf··on Credit card debt collection
It is a tool, I agree, but like any other tool it can be excessively pushed and alternatives can be prioritized or not.

As far as I can say, with a European state of mind, is that a credit card poses a risk and temptation for the average person. Not everyone is financially responsible, many times simply due to lack of proper financial education, and they deserve a little attention.

2rsf··on Ask HN: Take AWS to small claims court?
Amazon in this case: https://sellercentral-europe.amazon.com/seller-forums/discus...

Was it?
2rsf··on Camera crushes Lidar, claims startup
Clickbait as usual, it is one company's own claim.
2rsf··on Ask HN: Where to find open-source house plans?
Your last sentence is super important, having a sketch of a house is far from enough. Googling "construction detail drawings" will bring up endless drawings of all the small, but critical, things you need to take into account.
2rsf··on Heat your house with a mechanical windmill (2019)
Coincidentally I listened today to a podcast about direct water purification using wind turbines, the turbine is directly driving a water pump instead of going electricity->pump.

For water the benefits are not so much about efficiency, direct mechanical systems are the same or less efficient, but about simplicity and cost- those systems can be deployed and maintained in remote and poor areas without a need for costly technicians and parts.

2rsf··on Ask HN: How do I make sure my mom's garage door is closed?
That can be dangerous, what if grandma fainted on the doorstep?
2rsf··on I’m Done with All These “Success Stories” Online
I'm interested! I haven't failed in anything interesting, but would definitely love to hear stories to learn from.

I actually share the same feeling as you do, for example here in Sweden it is very common that many salary or career discussions ends up in someone bragging about being a freelancer and making tons of money- but how many failed that and how?

2rsf··on Casio G-Shock time sync radio
Why would I need that for? nanosecond accuracy? GPS indoors?
2rsf··on Ask HN: Alternative Jira UIs?
Use Jira's API and automate it using scripts?
2rsf··on Ask HN: Do developers have positive experiences with Scrum?
I had really good experience with Scrum in a small product team inside a big company, but the team acted as a startup inside a company, had a lot of freedom, schedules were flexible and budgets were large.

Then I had decent experience with scrumban in a team at one of the giants, but again we were lucky to be delivering utility products and not to end customers so we had a lot less dependencies.

2rsf··on Ask HN: Do developers have positive experiences with Scrum?
Since you mentioned SAFe I assume your company is not small, I have never met a good way to really be Agile in bigger companies (there might be rare counter examples, I know)
2rsf··on Banks fined $549M after senior execs found texting on Signal, WhatsApp
It's not about "texting" but about

> Banks with employees covertly texting about official business on apps like Signal, WhatsApp, and iMessage have been caught red-handed. Now federal agencies are charging banks with violating laws requiring recordkeeping on all business matters.

2rsf··on Turns out nobody cared about panel gaps
Definitely at the beginning, but this is no longer the case in many parts of the world where charger coverage grew widely, newer cars are adopting Tesla's NACS as charging ports and Tesla opening their network to others.

An anecdotal example from Sweden- there are no Tesla chargers available closeby for people in the big Stockholm metropolitan area.

2rsf··on Ask HN: What is the most exciting thing you have learnt this year till now?
Does the Dutch authorities think that riding without an helmet is safer for YOU or is it a game of big numbers- more people will ride if there is no helmet requirement which is better and safer for the community as a whole?
2rsf··on Akin’s Laws of Spacecraft Design
Most of them apply to software as well
2rsf··on A Critical Problem (2017)
A senior software tester here, welcome to my life
2rsf··on Ask HN: How can I reach WhatsApp product managers?
LinkedIn?
2rsf··on Ask HN: How do you manage your personal finances?
Actually using cash has its benefits, you subtract fixed expenses from you monthly income (rent, estimated utilities etc) and take the rest in cash, maybe weekly. This way you have a really good sense of how much you have at any given point.
2rsf··on Ask HN: How do you manage your personal finances?
What are your needs? you mentioned that you need something daily, why?

What do you want to achieve? balance at the end of each month, or "can I afford another latte today"?

For the first a spreadsheet can work great, preferably with some system to arrange your budget, but that's not about tooling but simply being disciplined. For the second I don't think anything will last- writing every expense is not scalable.

2rsf··on Civic honesty around the globe (2019)
Not entirely according to my experience, the simple Assa Abloys are indeed rather cheap and easy to change. But the more secure, thus approved by insurance, can be tricky since they contain traps.

There are instruction available on how to change them, but even me, and I am not afraid of DIY, called one of the many locksmiths around here in Stockholm.

2rsf··on Why are there no startups in the real estate construction sector?
> Melbourne that was put together over a weekend

Do you mean a skeleton laid on already poured foundations with water/sewage/electricity drawn, and ready for finishing after this weekend? finishing, carpentry, windows, internal plumbing and electricity takes a lot more to complete than the skeleton itself.

2rsf··on Tell HN: Nearly all of Evernote’s remaining staff has been laid off
With git you are less bound to a specific provider and your "software driver" is simpler and more standard

Which one is the most future proof? I recently tried Organice, even though it has a different feature set, because is is basically future proof even if the hosting company tops functioning
