Fredej··on DevDegree: Work at Shopify and get a free CS degree in parallel
From the linked page:

> Applications are welcome from anyone with an appropriate combination of academic achievement and industrial experience; a first degree in a related discipline may be useful, but is by no means necessary.

> Each MSc within the Software Engineering Programme is available only to part-time students; there is a separate MSc in Computer Science for full-time students.

I believe the full time study noted here is what you linked to.

Fredej··on A sticky problem that evaporated
I do think there's some value in being able to tersely express your exact point to a peer.

For example "a random process" could mean "any process in existence" whereas "a stochastic process" clearly states stochastic as being a property of the process.

I however agree that things can sometimes get a bit wrapped up in sounding cool just to sound cool.

Fredej··on Ask HN: Best book / resources on leadership, especially for tech teams?
I'm reading through it and absolutely loving it so far. They're able to succinctly capture concepts I have had trouble defining.

Are there any specific parts you'll recommend? Or anything I should skip?

Fredej··on Pagers, faxes and cheques: Things that might seem obsolete, but aren't
In Denmark we have a secure (government controlled) email for communicating securely with government entities and banks. It's where I receive any medical updates from my doctor and any official information from the government. I also receive my payslip, pension info etc.

It has cut down a lot on paper usage and made communicating way more efficient.

Fredej··on Pagers, faxes and cheques: Things that might seem obsolete, but aren't
I feel like a lot of this is rooted in some assumptions that are not being said aloud that you may not even be aware that you have. This is no in any way an attack on you - I find this entire thing absolutely fascinating. I've seen a check twice in my life: One time and old lady tried to pay with it, when I was working as a cashier - I had to call in help, as we were no longer being trained in how to accept them. The other time, I had to get hold of one when I was studying in the US, as I had to pay some fee that was only payable by check. Took me a month and cost me $30 to convince my bank to help me with it, as they told me they weren't sure they could even do it - they hadn't done it in years.

For context, I'm from Denmark.

First of there's absolutely nothing secret about our account numbers. All they can be used for is for transferring money _to us_.

No one carries cash around. Ever. Anywhere. I have not paid anything by cash in at least... I don't know, 10 years? 15? It's mostly used as gifts. Taken out of the bank, handed over, then carried back to the bank.

Basically all banking can be done online or via app. The only time I visited my bank was in regards to my mortgage, and even most of that was handled by email. If I want to do a direct deposit / bank transfer, I can just log into my app and do it. Takes maybe 1 minute.

However these days, most private transactions are done using an app called Mobilepay. Nowadays every single person has it. It's completely free to transfer money for regular people. You can also set up a business account, which I believe may carry a fee but it's minimal (just checked, 10 cents pr transaction in the priciest tier - roughly 4 for the cheapest).

For something like a woodworking business, the way to handle business-to-business transactions, you would probably go with something like an invoice. That's usually completely automatically handled by (free )software, and would only really require the other persons email to get started. The other person receives an invoice with (for example) a direct deposit address and an amount. The transfer is free and require no setup from the payer.

Internet access is everywhere and incredibly cheap. As en example, 6 GB and 6 hours is $10 a month, unlimited data and hours is roughly $20 a month.

Check bouncing is not a thing. You can verify the payment before you deliver the service. Mobilepay payments are instant - I get a notification on my phone that I have received the money as soon as the other party finishes their transaction.

Fredej··on Serverless Components
As someone who's always late to the party on these things (I just picked up Docker this year! Yay!) this seems like exactly what I've been missing when trying to pick up serverless.

Granted I haven't really tried building anything yet, but part of that is that I needed a way to get an overview what could even be done. This seems like a nice way to get introduced.

Fredej··on Running an eInk Display with Elixir, Scenic and Nerves
Where did you get a "nice unused eInk display" from? :) I've been meaning to tinker with one at some point, but haven't gotten hold of one yet.
Fredej··on Ventilen, a Danish organization to address loneliness in young people
There are other organizations tackling that issue.

People doing something to benefit others should not be looked down on just because they could spend their time tackling another problem.

Fredej··on Ask HN: What do you do with your Raspberry Pi?
Could something like this be used for synchronization in such a scenario? https://ncase.me/fireflies/
Fredej··on Raspberry Pi 4
According to the article the NIC is connected through dedicated RGMII - not through USB3.
Fredej··on Raspberry Pi 4
Looks like the ethernet is connected directly through RGMII - meaning the USB 3.0 controller is likely completely out of the picture. That would mean you can run full throttle ethernet without affecting the USB speed at all.
Fredej··on Mazda is purging touchscreens from its vehicles
Well, it's a thing specifically to stop people from fiddling with their phones.
Fredej··on What a Midwife Wishes People Knew About Her Job
Yeah, same thing in Denmark. When my girlfriend gave birth, we had 3 midwives assisting. When she lost what they deemed to be too much blood, they called in a doctor to take a look. Everything was fine. If she hadn't passed some specified threshold for bloodloss, we would not have seen a doctor (or a nurse, come to think of it) at all throughout the birth. Only midwives.
Fredej··on I Tested the Saving Technique That Promises Retirement at 40
Honestly I found none of that unethical.

If you're able to live with a lower consumption you should not increase it just to "not harm the economy". On the contrary I would find it unethical to increase your consumption beyond your need.

To your second point, I don't find it compelling either. First off, the FIRE way requires some amount of restraint and discipline - in many ways it's like dieting. It's good for you, but that doesn't mean people will do it - it will continue to be only a subset of people. Secondly, how would the system would adjust? What would be the driver for lower wages? The method is basically to save and invest half your income - that doesn't depend on your income. The people are still equally skilled, working equally hard during their working years. The output at their work while they work remains unchanged.

If anything it might drive wages _up_, as people would require increasingly higher compensation to stay at work, if the alternative is to live happily and safely without working.

Fredej··on You probably don't need a single-page app
It's funny how Google has been banging on about "just a few milliseconds of extra loadtime and your bounce-rate increases!" while in Gmail it's like they think the product is so good, people should be willing to wait 10 seconds to view their _mail_.

The reason I'm even reading this comment section is because I wanted something to do while waiting for Gmail to load.

Fredej··on You Can Now Run Windows 10 on the Raspberry Pi 3
I believe Win10 license price scales roughly with processor power, so it might be fine.
Fredej··on Letter from Tim Cook to Apple Investors
Basically yes. But the frequency used for PWM is usually _way_ higher than what should be realistically visible to the human eye - If it was me, I'd probably use a couple of kilohertz.

Not sure how specifically it's done for OLED though.

Fredej··on Writing Network Drivers in Rust [pdf]
Hah, I was reading this thinking "That sounds so much like Aalborg". I'm so incredibly happy I went there :)

Here's another report from MIT from earlier this year, reporting largely the same, placing Aalborg at 3rd or 4th depending on the method used [0].

Fredej··on HTTPS-Portal: Automated HTTPS server powered by Nginx, Let’s Encrypt and Docker
I'm also still not on the docker-wagon and would like to know what I'm missing out on. Most of my stuff is python. Why is docker better than virtualenv with a requirements.txt file?

From this description it seems to solve the same issue.

I could imagine something like environment variables, but on the other hand that's something I've learned not to keep in version control, and putting it in docker would be exactly that, no?

Fredej··on The use of "blacklist" is offensive
Think of the orphans!

When i think master/slave i think SPI master/slave, where the slaves only do as told by the master. In which case the primary/replica relationship would not be suitable, while the master/slave relationship is descriptive of what actually goes on.

If we have one (in my view unoffensive, but that might be a cultural thing) term which adequately describes the relationship - why not use it?

Fredej··on Bootstrapping an Online Fabric Shop and Growing to $20k per month
Can't you just give a lower price at 10 yards and again at 50 yards for example? Then you solve your baked in price issue and get to offer discounts on high amounts, incentivizing buying more.
Fredej··on Hidden work when launching a SaaS
I'm in the process of building a SaaS and looked briefly at Chargebee. Right now I'm trying to stay as lean as possible so I quickly wrote of Chargebee as something that would cost money.

The fact that you have a freemium tier completely changes my perspective on that. Guess I didn't spend enough time looking :)

I'll check it out!

Fredej··on Australia’s new real-time banking payments platform
How often do you have outlays for another person or give someone cash?

The application can be used for any transaction. I usually use it if I've been out with some friends, then it's super easy to split the bill afterwards. Or if going shopping. Or if we share a taxi.

Before we would either settle in cash or by trying to spend approximately the same. Now everything is done this way.

That's atleast the way it works in Denmark.

Fredej··on How do you build a healthy city? Copenhagen reveals its secrets
Pretty good public transportation. Metro, busses and trains will bring you most places.

I've lived in Copenhagen for 3 years now and don't own a car. I am not an outlier.

Fredej··on Ask HN: What's the recommended method of adding authentication to a REST API?
Could it be a possibility to generate a keypair on the machine and then attempt to register itself to your webserver supplying client-name, IP and public-key. Then you would be able to see and OK any attempts to connect. Once you've OK'ed it, it would be able to authenticate and communicate normally as an authenticated device.
Fredej··on Basecamp doesn’t employ anyone in SF, but now we pay everyone as though all did
They are willing to pay up to what the work is worth for them.

The work is not worth more just because you happen to live in the bay area.

Fredej··on What Needs to Happen Before Electric Cars Take Over the World
That's true in the short term, but one of them has to be the first to move. Shifting from coal to renewables does nothing for the environmental impact of cars in an all-ICE system. If we get a larger percentage of electric cars, the impact of switching to renewables will also increase.
Fredej··on How I recovered cryptocurrency from a broken laptop
Exactly. I've made this point before: The least appealing thing about crypto to me is one of the selling points - That I can be my own bank. I don't trust myself nearly enough to be my own bank. I want to pay someone I trust to take care of that for me. I don't want hacking or forgetting a password to be something that in any way affects my holdings.
Fredej··on How I recovered cryptocurrency from a broken laptop
I'm not the guy you replied to but:

> Do you only use a hot wallet for all your coin?

No.

> Do you keep your savings in your checking account?

Yes! :)

Moving coins manually between a hot and cold wallet is a hassle and what I would consider a significantly worse user experience than what exists today.
