If 1 watt is 1 joule per second then, honestly, what are we doing with watt-hours?

Why can’t battery capacity be described in joules? And then charge and discharge being a function of voltage and current, could be represented in joules per unit time. Instead its watt-hours for capacity, watts for flow rate.

Watt-hours… that’s joules / seconds * hours? This is cursed.

Yeah but which 3%? It's important.

There are a lot of Steam gamers with 5 games in their library who log on once a month. There are a few Steam gamers with 5000 games in their library who are permanently logged in. There's folks who play one game obsessively, and folks who tinker around with many games.

I'm willing to bet that the 3% are the kind of people who buy a lot of games.

I'd love to see that "what percentage of games have been bought by people on which platform?" metric. I think it'd be a lot more than 3% on Linux, even if you count Steam Deck as a separate platform.

Lots of things get invented / discovered multiple times when it's in the air. But just because Newton (or Leibnitz) existed, doesn't mean Leibnitz (or Newton) were any less visionary.

For your very specific question: have a look at the sorry state of what's called 'regular expressions' many programming languages and libraries to see what programmers left loose can do. (Most of these 'regular expressions' add things like back-references etc that make matching their franken-'xpressions take exponential time in the worst case; but they neglect to put in stuff like intersection or complement of expressions, which are matchable in linear time.

No such thing as a stupid question.

If you plug in a machine at home, it is behind the router, and behind the router's firewall.

If you want more of a firewall locally, something as simple as an EdgeRouter X can get you started easily with this excellent guide: https://github.com/mjp66/Ubiquiti

The nice thing about using cloudflare tunnel, is theres zero ports to expose, ever. The cloudflare tunnel app running on your local machine is what connects out to the internet and takes care of creating a secure connection between cloudflare and your machine.

If you want to forward more than one port to the machine, you could use something like cloudflare to forward to a machine on your home server, and then have the nginx proxy manager or something send the traffic around internally.

It's totally fine to start with cloudflare, and if you aren't already, something like Proxmox (youtube tutorials are pretty quick) gets you up and running and playing pretty quick. Feel free to ask any other questions you like.
by j45 | 2025-12-22 01:45:36+00:00
Thanks. Not sure of your point.

The firewall could run on a piece of dedicated equipment, where it might not be a server, or it could run in a container, on a dedicated computer, which might be the server.

Again, I'm only speaking about what I have experience with in addition to my past experience and have surprisingly found to run well despite thinking I'd never self-host again.

I resonate with this. I enjoy reading people's technical, artistic and personal writings. How they built, solved, or learned something new. Their favorite tools, workflows. Favorite authors, concepts, interests. @simonw is a great example of this kind of openness and working in public. I'm learning how to do that in my own way.

It makes the world friendlier, more welcoming for beginners and life-long students. It also creates a sense of community and human connection, which is often cynically exploited in today's society.

I feel like these exact same arguments were made with regard to tools like Photoshop and Dreamweaver. It turns out we can still build websites and artists can still do artist things. Lowering the bar for entry allows a TON of people to participate in things that they couldn't before, but I haven't seen that it kills curiosity in the folks who are naturally curious about things. Those folks will still be around taking things apart to see how they work.

Company says safe limit is 70 meters, about 200 feet.

Easy to build infra and other stuff that far away, especially in locations where this is meant to be used.

There are many aspects of safety

1. If the puncture is due to hurricanes, etc, the danger is non existent. The hurricane will blow away the co2 in no time.

2. If the puncture is due to wear and tear, then the leak will be concentrated and localized. It could naturally diffuse.

CO2 meters can be installed around the unit for indication.

Oxygen masks can be placed around the facility for emergency use.

The dangers are very much mitigatable.

Mm. I'm glad for you that you can just think about your problems harder and get better, but that's not the reality of it for most people with depression.

Meds don't magically make you happy and they don't magically get you out of fixing the problems in your life. They make it easier and therefore possible to do so. I'd describe it as the crane that lifts up the heavy weight enough for you to shuffle out.

If you can just think harder about your problems, by all means, do that. But there's zero virtue to rawdogging it when help is available, especially as this can easily lead to an isolation spiral and become deadly.

Small "except". :)

With the amount of automated bots that port scan looking for anything/everything that's open, as well as scanning DNS records for server IPs that could be targeted, one of the nice patterns of cloud hosting is how application and data servers are hosted behind firewalls of some kind, to effectively be internal.

As for what's exposed to the web, let's say the payload of a website, if there was something vulnerable in the javascript, that could be a weakness hosted anywhere.

Cloudflare can also help achieve this without too much fuss for self-hosted projects, be it personal, and production grade, assuming the rest of the trimmings are tehre.

There’s little reason to avoid prescribing medication alongside other approaches. It’s not that meds are the only option or they should be reserved for the most severe cases, it’s people’s reactions are different and there’s no way to tell without trying them. For some people they really do work wonders and you simply don’t know ahead of time.

Not everyone has a support structure they can count on as they fall apart. So some people just need help to get through a rough period even if a solution isn’t long term viable. When a spouse dies being able to function for the next few months can mean keeping the roof over someone’s head.

It's easier to figure out for people that measure power in watts and time in hours ... 1 kW for 1 hour is 1 kWh.

That camel's nose was already in the tent with the mAh thing in phone/etc batteries, now with electric vehicles we're firmly in kWh land.

Not to mention that's what the power utilities used all along ...

I wouldn't change definitions like that just because the technology changed, I'm talking about the ability to analyze control flow and logic, not necessarily put code on the screen. What I've seen from most vibe coders is that they don't fully understand what's going on. And I include myself, I tried it for a few months and the code was such garbage after a while that I scrapped it and redid it myself.

It's clear, from watching Russia fail to be completely sanctioned that this is not watertight. The question I have is: have these sanctions added a money laundering tax to doing business? How much? What is the cost of enforcing the sanctions vs the added cost and is that worth it?

I don't know if this has been explored, bit I think it's an interesting follow on to "all or nothing" watertight sanctions.

Accusing anybody who doesn't love the government of "spreading propaganda" is not a sign of knowledge. It's a sign of an obsolete 20th century mindset and perspective on life.

Next perhaps you're going to accuse me of "Staatsfeindlichkeit", which the German leadership was screaming in their denouncements, before the people tore down their walls.

"Verunglimpfung des Staates" - "Insulting the State", this awful, awful crime, is something I'm going to continue doing however I fancy. Millions of people were killed for that right, so it's not something I'm ever giving up.

Fifty years ago, I was given a coin bank styled after the red Danish Post letter box. That was in Solvang, CA. As these Danish immigrant-character communities (look also in Elkhorn, Racine, Greenville, etc) are little time capsules, you may have to travel to America to find a replica red slot to drop your letter.

The article wasn't clear how letters from outside Denmark will be handled, but maybe that's implicit in the Dao contract.

EDIT: maybe Royal Mail was never the Danish term, but I thought it was on a Lego set too...

I'm a Japan resident... whenever I'm outside of Japan, friends have to remind me to not "leave my laptop out like that" nor hold wads of visible cash or keep my smartphone on the table.

Cafes... I'll go to the bathroom or whatever and just leave my stuff all out on the table, meanwhile with my high-end bicycle parked unlocked and out-of-view outside.

It, of course, isn't like this EVERYWHERE in Japan, but many many places.

As someone medicated I actually fully agree with you.

Depression is also a broad spectrum condition (much like autism). Years ago I watched this lecture by Sapolsky[0] and it really helped. Breaking down the different classifications is really helpful. The SSRIs always made me feel worse, and this (along with a lot of other research) helped make sense of it. A few years back I was diagnosed with ADHD and a psychologist friend encouraged me to give Adderall a try. It was the first time that medication "worked" and it really made a big difference in my life. The big reason why being that psychomotor retardation and anhedonia were my biggest symptoms. When coupled with an anxiety disorder it creates a strong negative feedback loop.

But here's the thing: medication isn't the cure. For me it alleviates (not eliminates) symptoms but at the end of the day it still requires work from me to ensure I create a positive feedback loop and don't let myself fall into that destructive loop. This is all stuff I had to learn on my own and through reading and seeking out friends with people who are more experts in the area. That's where I think our care system fails.

The best thing I can recommend to people is to be introspective. Each journey is personal, but whatever your issues are try to find the early warning signs. For me it can be little things like the dishes piling up or my desk getting messy (these seem you be common). Things like depression build up, so look for the signs. And most importantly, open up. This was the hardest for me and makes me feel demasculated and embarrassed much of the time. But I've also found it to help build stronger relationships with my partner and friends. That it helps open a door to communicate both ways. Maybe you open the door for you, but you also open a door many are too nervous to open themselves. It's worth the discomfort and gets easier with time. (Talking behind a handle is a great way to start too. So make alt accounts if you need to. That's how I started)

People who cannot learn hard things don't have time, or they think they don't have time. Actually they try to fake their way through because they believe it is impossible or at least too late to sort things out properly.

The so called geniuses seem to have rather lax lifestyle, like free evenings to really make their homework. When you constantly think you're in hurry you've pretty much lost the game. You're just trying to get by and learn very little.

Yes, that is the same law in California, but so many people drift through stop signs that the guidance is close to meaningless.

In addition, there are 4-way stop signs all over SF and tourists regularly comment on how they work here.

The law is clear - yield to the right, but that is a pretty slow system in congested roads.

The local custom in SF is that someone is usually obviously first, rightmost, or just most aggressive, and opposing pairs of cars go simultaneously, while being wary about left turns.

Of course pedestrians have right of way in California, so someone in a crosswalk gives implied right of way to the road parallel to the person's crosswalk.

The result is 2x or better throughput, and lots of confused tourists.

So ... with the lights out on a Saturday before Xmas, there was a mess of SF local driving protocol, irritated shoppers, people coming to SF for Xmas parties, and just normal Saturday car and foot traffic.

I thought Waymo did pretty well, but as I said, I didn't see any ones that were dead in the middle of the street..

A PhD means you can do novel research. As a full stack developer what novel subject(s) did you explore? That is the middle you are missing.

A big part of the problem is that you were spending time with tech stacks and frameworks. These have almost no practical utility value aside from attaining employment in a low skill area of software. I am saying that as a former 15 year JavaScript developer. Instead use your research background to solve real problems faced by businesses and users that you can measure.

The internet was a big part of it. Most home users did not have internet access in the System 7 days. When it came out in 1991 no country had more than 1% of its population with internet access. By the time Windows 95 came out around 10% of US users had internet access.

It wasn't until 2001 that the US reached 50% of users having internet access.

Without internet there wasn't really a good way to distribute updates to most users.

As a developer in that era working at a company that made software for PCs and Macs it was great. It meant that the way most users would get our software was buying it on floppy disk (or later CD) from a retail software store like CompUSA or Egghead.

We'd only make more money from someone who bought our software if that software made a good enough impression that they bought more of our software. We'd lose money if any software went out with enough bugs or a confusing enough interface or a poorly enough written manual that a lot of people made a lot of calls to our toll free tech support.

This was great because it largely aligned what developers wanted to do (write a feature complete program with a great UI and no bugs) and what management wanted (happy users who do not call tech support).

With internet giving us the ability to push updates at almost zero cost and as often as we want people who release incomplete programs early and add the missing parts in updates are going to outcompete people who don't release until the program is complete and nearly bug free.

Once you get there it is not much of a leap to decide that what you are really selling is not software to do X but rather the service of providing software to do X. Customers subscribe to that service and you continuously improve its ability to do X.

You could argue that, with Windows there is a legitimate place to direct your rage at, but the action of directing your rage does not actually have any effect on improving your experience. With Win and Mac, no one cares, because they already have their customers locked in and tight, they will accept any experience degradation. With Linux, you are not a customer so no customer complaints, but still arguably much better support.

From the article:

> Danes will still be able to send letters, using the delivery company Dao, which already delivers letters in Denmark but will expand its services from 1 January from about 30m letters in 2025 to 80m next year. But customers will instead have to go to a Dao shop to post their letters – or pay extra to have it collected from home – and pay for postage either online or via an app.

Cane to say the same.

I have a Garmin "smart" watch (with every app notification etc disabled) and I love the fact that I can do almost two weeks of exercises (ride, walk, gym) without needing to charge it. The bike computers are also solid. But sadly the UX of the software on these leaves a bunch to be desired, and I've been bitten by many software and firmware bugs in the last years... Including months for which HRM would randomly and persistently drop it's value from say whatever the real value (say 145 for argument sake) to 80.

I'm pretty open (check out my HN handle, if you don't believe me), but I'm also retired, and there's not many ways folks can get a handle on me. I have an ... eclectic ... life story, and it has supplied me with a healthy dose of cynicism and hardness, that makes me a not-so-easy mark.

I'm also very much a person who enjoys other people; especially the ones that are hard to get along with.

I've learned that being open, on my end, can encourage others to be more open to me. I don't have any nefarious motives, and am quite trustworthy, so I like to think I'm a "low-risk" person. I'm quite aware that the same can't be said for many others, and understand it, when that is cast onto me.

Watching anime, looking at anime artwork, reading manga since 2006.

Why else would you criminally investigate artwork websites if your aim is not to arrest artists and those who look at their artwork? (And eventually use them as an excuse to show why encryption is evil, and how "evil artists" could be caught more easily if it was backdoored.)

If you're looking for news, there won't be any yet as, as I said, I'm still under investigation.

Dredging up common and mostly uncontroversial things that were said in 2010, but are now apparently very controversial, is somewhat of a sport for some people nowadays. There are some out there who would love fans of Ruby on Rails to suffer because of its association with DHH. It's not always entirely rational, so how could I ever predict what unhinged individuals in 2035 will take issue with on my blog? Everything online is preserved, so it's easier and safer to just not to participate at all.

To me, it doesn’t matter how cheap open AI codex is because that tool just burns up tokens, trying to switch to the wrong version of node using NVM on my machine. It spirals in a loop and never makes progress, for me, no matter how explicitly or verbosely i prompt.

On the other hand, Claude has been nothing but productive for me.

I’m also confused why you don’t assume people have the intelligence to only upgrade when needed. Isn’t that what we’re all doing? Why would you assume people would immediately sign up for the most expensive plan that they don’t need? I already assumed everyone starts on the lowest plan and quickly runs into session limits and then upgrades.

Also coaching people on which paid plan to sign up for kinda has nothing to do with running a local model, which is what this article is about

The AF 449 was in a stall, and the pilots panicked and did exactly the wrong thing. The pilot came out of the lavatory and immediately realized what was wrong, and pushed the stick forward. But it was too late.

If the captain could figure it out, so could the computer.

I recall another crash, not so long ago, of a commuter plane where the wings iced up a bit and the airplane stalled. The crew kept trying to pull the nose up, all the way to the ground. They could have recovered if they pushed the stick forward - failing basic stall recovery training.

There are many others - I've watched every episode of Aviation Disasters. Crew getting spatially disoriented is a common cause of crashes.

If you have an architecture document, readmes for related services, relevant code from related services and such assembled for a LLM, it can do a pretty solid review even on microservices. It can catch parameter mismatches/edge cases, instrument logging end to end, do some reasonable flow modeling, etc. It can also point out when uncovered code is a risk, and do a sanity check on tests.

In order to be time efficient, human review should focus on the 'what' rather than the 'how' in most cases.

Maybe the German, French, and Russian classics from around 1830-1950. The material that was considered the backbone of modern literature. At least War and Peace was mentioned in the list.

They might be a bit heavy reading but pretty much understandable even for less educated reader. The literature before that is written for people who know the Bible, Homer, Ovid etc, classic philosophies and European history thoroughly. For others it looks like nonsense or they might read it but not really get much out of it.
