slau··on A guide to Home Row Mods
Great write up. I switched to a 36 key keyboard a few weeks ago, which means I don’t have the physical space for ctrl/shift/alt/cmd. My typing speed has screeched to a grinding halt, the first few days I was struggling to find many keys, highlighting terrible and horrible typing habits I had picked up over the years.

It’s been a lot of fun re-learning how to type. It has made me much more conscious about how I type. My speed on a regular keyboard hasn’t changed, however it has improved my typing hygiene drastically.

Homerow mods are great!

slau··on Deep-sea diver was cut off from his air supply for half an hour. He survived
Interesting. Maybe I got confused because I remember watching Simon Mitchell’s talk[1] about the hydrogen dives with Richard Harris. He mentioned that the Comex Hydra tests revealed hydrogen was significantly cold to breathe.

If I’m not mistaken, hydrogen has a lower heat capacity than helium. So how come helium doesn’t feel cold to dive? Could it also have to do with the actual percentages?

Mitchell mentions that for their 245m dive they’re using 4% O2, 91% H and 5% N2. Could it be that most average trimix doesn’t incur a temp penalty because when we’re diving 30/70 it just doesn’t have that much of an affect?

I don’t entirely disagree with you, however him switching to his emergency cylinder could still reduce his core temperature very quickly, no?

The heliox mixture supplied by the ship/bell is most likely heated/insulated (by the same warm water heating his suit). Once he switches to the emergency reserve, the 2-300 bar gas gets expanded to 10 bar, massively cooling it down. That cylinder was most likely already at 7-10°C (whatever the ambient temp was), so the heliox is probably coming out at just above freezing. Thoughts?

I haven’t dived trimix yet, but I know many in my club have indicated it’s easier to feel cold when diving OC trimix, and recommend it as yet another reason to only dive trimix on CCR.

slau··on Ask HN: Where do you browse and chat outside of here?
A friend of mine mentioned RSS a few months ago. I asked him for a copy of his feed, and he gracefully sent me a curated list of about 30-50 blogs, job boards, and news.

I’ve removed some and added some. Anytime I come across an interesting blog post (here, Lemmy, Masto) I add the blog’s feed to my RSS reader. If the long-term content doesn’t match my taste I remove it unceremoniously.

slau··on Dear hosters, you are selling wood, not furniture
Same with Cognito, to be honest. The vendor lock-in is so strong, the abstractions leak through every crevice, not even full AWS shops can tolerate it.

I truly believe this is why email-based logins have become quite popular. You delegate the security of the authentication to the client (whether they’re a B2B client or B2C doesn’t make much of a difference), you don’t need to have 2FA, password reset flows, etc.

slau··on Ask HN: Where do you browse and chat outside of here?
Mastodon and RSS feeds. I’m also trying to write more long form stuff, and that definitely helps keeping conversations going.

I check out Lemmy maybe once or twice a month.

slau··on Calls for boycotting US products spread in northern Europe
The irony of using Facebook to coordinate an American boycott is spectacular.

It seems Scandinavians can’t even imagine organising anything without creating an FB group for it (I should know, I’ve never been on FB and it has been a hurdle ever since I moved to DK 10 years ago).

slau··on USAID's chief economist has resigned. Here's why
It takes a particular kind of mind yoga to look at Trump and Musk’s divestments in the past few weeks and conclude “damned democrats”.
slau··on How often should you poo?
In January I tried going vegetarian. It turned out to be a very easy transition, much easier than I expected, but the most surprising change was the quality of my BMs.

It took about a week to adjust, but since then, it’s perfect quality poops every time. I’ve since adopted a flexitarian diet, and only had meat a couple times since the beginning of the year.

I have no idea whether it would help you in any way, shape or form, but I’m a much happier pooper since dropping western-style meat consumption.

slau··on Tesla protests gain momentum while the hate is dividing Tesla owners
In Denmark, electric is about 5-10% cheaper with my hybrid compared to gasoline. It also has the convenience that my car can charge at the car park without me doing anything.

Interestingly, the savings from parking fees are a thousandfold more worth it than the gas stuff.

slau··on The Unbrickable Pledge
What are people’s thoughts on this product? Does anybody have it and what do you use it for?
slau··on As more local cinemas close, residents are forming nonprofits to buy them
I live in the Danish equivalent of Hollywood and TV production. The local movie theatre is run by volunteers, and costs about 30-50% less than what the commercial cinemas do. As far as I know, it has been community run for as long as I’ve lived here, or about 10 years.

You can rent a theatre for you and your friends. You can sponsor a chair and have your name on it.

It’s incredibly wholesome to have a Danish grandma handle the confectionary stand.

They typically run their movies much longer than commercial cinemas. They’re trying to maximise the revenue for each movie they pay for, I guess. This also means that even if a movie gets review bombed, we can typically still catch it for a good few weeks.

Given the choice, I would much rather go to a community cinema than a commercial one. Yes, the sound setup isn’t as good and the screen is a bit smaller, but the price is much more reasonable and the model is much more sustainable.

slau··on Reddit CEO Says Paywalls Are Coming Soon
No offense, but this sounds a lot like a comment made by someone who a/ doesn’t understand blockchain, b/ doesn’t understand high traffic websites. I don’t understand the former but have a fair understanding of the latter, but even then not at the scale of Reddit.

Blockchain is “great” for distributed data. How many people do you know would want to run a node that hosts a few TB of data and requires equally copious amounts of bandwidth?

If you meant that you think we should have federated services that interact with each other using an open protocol, I’ve got great news for you! Mastodon uses ActivityPub to federate and is a Twitter replacement. Lemmy and KBin both implement ActivityPub as well and are more geared towards forum-style use like Reddit.

Regardless of the underlying technology that’s chosen, I think the real issue is that everything ends up being centralised. That gives individuals/companies too much power. If every community has its own subreddit, then each reddit policy change is going to offend/infuriate some part of the user base.

If a community forum decides they want to ban $content, it only affects that community and nobody else cares.

Every forum doesn’t need to be connected with everything else. There’s very little benefit from a scuba diving forum to see posts about tennis or sneakers. The only reason Reddit is popular is because instead of having aggregating clients that show a bunch of different topics from different interest groups, we let the servers be the aggregators.

I guess what I’m describing is usenet, where your usenet client just shows you the things you were subscribed to. Gah I’m old.

slau··on Why We're Falling Out of Love with Tesla
I had never thought this was a pedal issue. It’s a very significant problem in busses here in Copenhagen. We’re being jerked around continuously and it makes the ride very uncomfortable.

On my car, it’s not an issue. The dead zone around the coasting point is wide enough and predictable enough.

I always assumed the bus drivers were either incompetent or lacked empathy, but it being a hardware problem could make way, way more sense.

slau··on Why We're Falling Out of Love with Tesla
And yet, you perfectly understood what they meant, because words can have different meanings dependent on the context.

Luckily, GP made it abundantly clear he wasn’t talking about a beemer.

slau··on Elizabeth Holmes' PR campaign continues
People ascribe some kind of Robin Hood-esque virtue to Silk Road dude, even though he paid hundreds of thousands of dollars in an attempt to have 5 people murdered.

I’d rather never hear about either one ever again.

slau··on Ask HN: Is it worth it to post on the 'Who Wants To Be Hired' thread?
I got a job through a Who’s Hiring post that helped me move to Copenhagen, DK. I’ve gotten a few interviews through Who Wants To Be Hired, mostly interesting companies who then ask me to apply as if I was a regular candidate.

In one case, I got a very nice email from the CEO, I applied, but I was never told what kind of position I was interviewing for, so it was really tough to tailor my answers and focus.

slau··on Cc Hot Wife: Gmail exposes contact names
It's kind of impressive how much this post exposes how little knowledge the author has about email. Not the best look for someone who is trying to get hired for their dev skills.
slau··on Tell HN: Hacker News will not delete my account – is that legal?
Reading the CCPA, I have to agree with you: it’s useless. It specifically excludes public information, and OP clearly made those posts publicly.
slau··on Tell HN: Hacker News will not delete my account – is that legal?
I would argue that renaming the whole account to another account is not, in fact, anonymising it.

If dang wants to keep the content but properly anonymise it, then every single post would have to be unlinked from a single account. Every post should be attached to an unrelated random account.

/. used to handle this by having “Anonymous Coward”. Reddit has this with <deleted>. Because this is not a concept on HN (or at least, not an oft used one) I feel the “random unique accounts that post a single comment” is better than marking your posts as coming from “AC” as that would still allow sift through the search results.

This being said… if people wanted to keep your comment history… wouldn’t they already have fetched it by now? Especially if you’re publicly indicating you’re trying to get your account deleted?

slau··on Tell HN: Hacker News will not delete my account – is that legal?
How do you interpret “messages” as not including posts? I am very clearly replying with a message to you.
slau··on Next-gen Ethernet standards set to move forward in 2025
Do DAC cables really have a transceiver built in? I thought they were called “direct attach cables” and were limited in length because they “directly attached” one SFP module to the other one.
slau··on A story of three identical strangers
I’m not so sure both would be nurture. I also don’t believe the premise has anything to do with something as mundane as habits.

You could be a hardcore $political party member, but nothing about that is nature. That’s entirely a result of your environment.

As far as I understand, nature vs nurture is more designed to explain/blame academic performance, ability to manage money, pressure, etc. I remember hearing an old friend explaining it as “a way for the rich to justify why poor people shouldn’t be making financial decisions“.

slau··on Ask HN: How are you preparing for PEPPOL?
I’m using VISMA e-conomic to do my bookkeeping/invoicing. They launched an eInvoice system some time ago which I would expect was PEPPOL based, or something similar. They enabled it by default without informing anyone.

A couple of my clients didn’t see the invoice in my monthly email, so they asked me to resend it. I re-sent the PDF manually.

To address OP’s question: I don’t expect it will change much for me. The customer configuration will let me choose whether the invoice is sent by email or another way, and I’ll still create my invoice by clicking “book and send” in e-conomic.

slau··on Instagram, Facebook, and TikTok block democratic hashtags
I seem to remember being able to vouch for stories. Maybe the karma limits have changed? Or it is also very possible I only remember being able to vouch for comments and confusing the two.
slau··on Apple starts pushing AirPods owners into Transparency mode, with no easy opt out
I tried to remember when the last time was I used “Off”. I use my AirPods for about 4 hours a day, and I’ve never really had battery life issues.

This post will make me try it again though.

slau··on PEI Homeowner captures sound and video of meteorite strike on camera
For context, because it was not clear to me at all, PEI stands for Prince Edward Island, which is a province on the eastern coast of Canada.
slau··on Wi-Fi Router at CES 2025 Has a Connectivity Radius of 9.9 Miles
YouTube supports 8K@60 at 300Mbps. I think most cat videos should stream without buffering.
slau··on Ask HN: How can I learn to better command people's attention when speaking?
It’s also important to view a group conversation as a bonfire. You have to contribute to it and help it grow.

If you’re not saying anything that others can jump off from… then you can’t expect them to. Use a question sandwich: someone is talking about a place you’ve visited. You can then interject with “Oh you’ve been to Taipei? The hike to Elephant Mountain was incredible! What was your favourite part of the city?”

You don’t use the word “I”, and you pass the ball back to whomever was speaking. You brought fuel to the bonfire. You stoked it. If anyone concurs they’ll let the group know. If anyone else wants to jump in you’ve given them an opening. And the person you interrupted can either use your interjection to add to their story or they can keep going, but you didn’t prevent them from telling the story.

If instead you just say “Oh I’ve been to Taipei too” or “I really don’t like that show”, now you’ve put the burden of maintaining the bonfire on the person you interrupted. They have to now ask when, how long, did you like it, why not, etc.

I’m not saying OP was making these mistakes, but I’ve noticed these kind of patterns often. People love to talk, especially about themselves. Let them.

slau··on Back to basics: Why we chose long-polling over websockets
Long polling has nearly all the same disadvantages. Disconnections are harder to track, DNS works exactly the same for both techniques, as does load balancing, and DDoS is specifically about different IPs trying to DoS your system, not the same IP creating multiple connections, so irrelevant to this discussion.

Yes, WS is complex. Long polling is not much better.

I can’t help but think that if front end connections are destroying your database, then your code is not structured correctly. You can accept both WS and long polls without touching your DB, having a single dispatcher then send the jobs to the waiting connections.
