News for hackers. Stuff that matters.

Just a heads-up from Denmark: card payments went completely down last night, and it wasn’t just a local glitch. Stores all over the country were affected—POS terminals dead, ATMs offline, even online transactions failed in some cases.

The payment provider Nets has confirmed the outage, but says they still don’t know what caused it. According to their statement, there’s no sign of terrorism or foreign interference—just a mysterious, wide-scale failure in the core infrastructure.

Zettle also reported a "major outage" for card processing in Denmark around the same time. Everything was back online within before midnight, but the incident left a lot of people (and businesses) stranded, unable to pay or be paid.

This is one of the most cashless countries in the world, and it really showed how brittle the system can be. No clear cause. No clear prevention. Just… silence and fallback to cash (for those who had any).

It seems to make a server request when Generating a new maze. Making the maze working fully Client side should be doable..
Also in this regard USA is not a developed country but offers its citizens the same service as under-developed countries

Re:37signals Leaves the Cloud on Sunday October 23, 2022 @05:48AM (#33305772)
I didn’t listen to the accompanying podcast so I might be missing some details.

It strikes me that it seems like 37signals are just using AWS as a glorified virtual machine with maybe some db hosting. To me the big benefit of the cloud is using all the little services they provide, like s3, sns, sqs, CloudSearch ECS, cloudwatch and the list goes on and on. If we were to host all those service ourselves and keep them up to date the operating cost would be huge. Furthermore I work for a site that is very public and has a lot of for instance ddos threats hanging over head. AWS handles lots of ddos threats all the time and they a much better suited for handling that than our own ops team.

Reninds me a bit of the stirling engine. It also operates on heat differences. And it has also not been used as much as one would have thought possible.

I don’t see any, recumbent, trikes or velomobiles. Specifically the latter two are probably our best bets of replacing the car.

A shame it does not have a rss feed since this is exactly what I was looking for - but thanks

Ask HN: How do you follow news about browsers?

The browser world is moving forward very fast it is hard to keep tap on what is going on. For instance I missed this: https://developers.google.com/web/updates/2020/07/referrer-p...Does some kind of site exists that gathers news about browser updates exist?

Ask HN: How do you let go?

How do you let go of your work after the workday is over?In our industry many of us practically have our hobby as our job. This makes our jobs enjoyable in may ways. However it also makes it hard to let go and relax in the evening.For example I work for a pretty big national newspaper, and right now we have a major problem with our articles not being indexed by google. I have made some changes...

Just not idiomatic code
Re:Recursive fibonacci benchmark using top languages on GitHub on Friday September 28, 2018 @05:16AM (#18092002)
But I suppose not adding memoization will reveal the real performance of the language

The rigth way to do fibonacci would probably be to add memoization...

Hey, you should check out Terraform ( I am not affiliated, but a happy customer)

Ask HN: Single board computer instead of vagrant

I use vagrant to virtualize my work environment. However I think it would be cool to have some kind of a headless SBC with a quad core processor (maybe i7) where I could have everything hosted. This way I would have very good performance and still keep it separate from my main computer.I have considered using a cloud provider, but i like having the computer on my desk, and also using a cloud...

So funny how meditation has to be related to buddishm... When it is actually pretty universal and even found in christianity, which is what the western civilisation is built on, just sayin.

That is very interesting feedback. I am a developer from Be My Eyes. What could be done to make it less intimidating?
