xhrpost··on Archival Storage
The quote of LTO tape being much less prone to read failures (10^-20) vaguely reminded me of an old article stating that something like 50% of tape backups fail. I'm not in that side of the industry so can't really comment as to if there is some missing nuance.

xhrpost··on Minimum effective dose
I've done a lot of broad research on exercise in recent years. While there is certainly a dose dependent relationship with results, it's amazing how little you can do to get "some" results. A few stats from studies or articles I've seen in the past: - Just twelve minutes of exercise is correlated with positive health improvements - As little as two minutes of walking after eating has a positive improvement in blood sugar
xhrpost··on Software development topics I've changed my mind on
> REPLs are not useful design tools

Anyone have more context on this? I've never thought of a repl as a design tool. Does he mean loading your app in a repl, calling functions manually and then manually swapping them out in real time?

xhrpost··on WikiTok
Wonder what it would take to add a simple algorithm to this. Part of what makes short media apps (dangerously) addictive is that they eventually learn what you like and feed you more of that. An app like this with such an algo could help with the stickiness (and presumably get us away from the other apps at least for a little bit). "Oh this person likes science stuff, let's feed them more, oh they specifically like stuff related to quantum mechanics, let's place a summary paragraph from a related page topic in there."
xhrpost··on 417-megapixel Andromeda galaxy panorama took over a decade to make
That led me down a bit of a rabbit hole and I found this

https://en.wikipedia.org/wiki/List_of_galaxy_groups_and_clus...

So there are actually a few galaxies visible with the naked eye outside of our local group even. However, all are within our local supercluster.

xhrpost··on So you want to build your own data center
As a dev I recently sent my first AWS support request. Received a non useful response featuring factually incorrect statements about their own platform. Replied to support ticket, no reply. Sent email to two AWS reps, never got a reply.
xhrpost··on The trap of "I am not an extrovert"
Though often conflated, there is a difference between introversion (preference towards less external stimuli) and shyness (fear of social judgement). You may be a shy extrovert.

Also I can totally relate to the hyper fixation on "what does this person think if me right now with everything I say?" I wish I had a simple super effective answer but I think it just takes small improvements over time. In general, if you're willing to show a reasonable level of mutual interest in the other person, they will reciprocate and with practice this can be trusted such that the anxiety reduces. Also accept that some people will just not be interested or necessarily like you and that's ok, but hard at first for sure, especially if you've faced social rejection earlier in life.

xhrpost··on Clay – UI Layout Library
I'm not proficient in C. Does this "just work" or do you need to provide some sort of rendering environment like SDL?
xhrpost··on Everything I built with Claude Artifacts this week
Software is more than just the code to make a computer do something. It is the auditor's log of rules that were painstakingly researched and decided on over months, years, etc. A lot of time goes into deciding what the program needs to do and only after some decision is made is it written down as code. "Do we ship the customer order after payment is authorized or after the funds settle? Depends what we're selling maybe? What does the finance department think? Oh we have regulatory rules to follow, better make sure those are there too. Oh we need to be able to back-wipe PII on-demand as well. But maybe we need to retain certain attributes, let's schedule a meeting." Etc. This is where a lot of the value lies.
xhrpost··on Windows dynamic linking depends on the active code page
Is this what is meant when people say that Windows doesn't have stable APIs? I've not programmed windows/desktop software and have often been confused as to why if you're writing an assembly program, you have to use at least a little C if you want to make Windows system calls[1]. The compiler must be compiling the call into "something" so can't you just write that "something" directly in assembly?

[1]: The classic example being Chris Sawyer writing nearly all of Rollercoaster Tycoon in x86 assembly but requiring just enough C for the system calls.

xhrpost··on Show HN: A website for comparing protein powder prices
I'm sure you have a ton of suggestions but having an option to filter by sweetener type would be great. I'm trying not to buy anything with sucralose.
xhrpost··on Oura Ring 4
Would be neat for a smart ring to offer tap-to-pay but I don't think it exists yet.
xhrpost··on Xkcd 1425 (Tasks) turns ten years old today
I've gotten to the point where I now see the word "just" as profanity in our profession.
xhrpost··on Why I still blog after 15 years
Agreed. I think part of this shift came with the transition to use real names online everywhere. Now what you put out there really matters because you might be judged for it years later. So if you're limited in your creativity, why bother creating something you don't enjoy if it doesn't have the potential to make you money?

Personally I'm keeping my real name Gmail but I've created a no-name account on Proton and am starting to use that for certain platforms. I want to try and get back to something like the days of creating random logos in Gimp and posting them to my Geocities page that no one viewed other than a friend or two and I didn't care.

xhrpost··on In 1870, Lord Rayleigh used oil and water to calculate the size of molecules
Which is maybe part of the reason RAM needs to be so close to the CPU? Granted though most RAM access takes several CPU cycles.
xhrpost··on Dark Mode Sucks
> Is your screen too bright at night? Just turn your brightness down

It just doesn't work like that, even the lowest setting can be a blast to the eyes if the background is pure white. I have grown especially fond of dark mode due to getting woken up in the middle of the night due to on-call for work. A low brightness setting either makes things too hard to read or is still overly bright.

xhrpost··on DOjS – A DOS JavaScript Canvas with Sound
This is great work! I've been interested in having a ready to go dev environment for DOS where you just do straight INT 10H development like back in the day. Is it possible to compile work here to an actual x86 DOS executable that could run on DOS without this environment?
xhrpost··on Low Cost Mini PCs
Add an SD card to that cost as well as an ethernet adapter, maybe wifi too? I'm not trying to bash on the Pi as option in all cases, just trying to note that in some cases, particularly hosting local services, it's likely not the simplest choice. Uses where I can see needing a Pi over a miniPC? Maybe 4k video playback, I'm not sure how well these x86 systems from 2011 can do that while some Pi's IIRC have onboard hardware for h265 decoding.
xhrpost··on Low Cost Mini PCs
It's a fair point but as others have noted, these mini PCs can be very power efficient. I still need to hook up a meter to mine to see what the wattage is but I'm sure it's far below a typical desktop PC.
xhrpost··on Low Cost Mini PCs
Stunning value indeed, they got more RAM than my M3 I use for work. Edit: oh wait there are drop downs to change the specs, subject is max specs but initial price is the min specs. Still good though
xhrpost··on Low Cost Mini PCs
I've been loving the recent attention to mini PCs here. I've had hobby projects put off for a while as I tried to find the best R-Pi clone, only to buy one and struggle just to get it to boot. Then I pick up a used mini PC on ebay for like $42 shipped, power cord and everything and even a 500gb SSD. Now I have a server running at home and am actually working on projects again, oddly for probably less than what a Pi clone costs after you buy enough accessories to use it.
xhrpost··on SurrealEngine: Open-source reimplementation of Unreal Engine with playable UT99
A potential side project I keep coming back is reimplementing the dedicated server for an old game like this. Even years ago when the games were popular, I often found the DS challenging to run.
xhrpost··on Basic Mechanisms In Fire Control Computers (1953) [video]
There's a copyright notice at the start that says this film is owned by Periscope films. If this video was actually created by the US government, then it should be in the public domain.
xhrpost··on 17,000 AT&T workers across the Southeast strike over contract negotiations
I don't know a ton about unions so first I've heard of such a thing. How does this work? Isn't it illegal to prevent someone from joining a union? (Yellow dog contracts?)

Looks like it made some extra profit due to the volatility bump we just had.

xhrpost··on Ditch banks – Go with money market funds and treasuries
I think it's mostly tax exempt at only the state level, no?

For tax advantage, I've recently found out about BOXX. You get roughly the same growth as a typical HYSA, but the value is added as actual value to the stock rather than dividends. So if you hold for at least one year, you can get HYSA interest but only pay capital gains tax.

xhrpost··on The upstream cause of the youth mental health crisis is the loss of community
I've personally noticed that my own value of autonomy has often contributed to a reduction in social activity and community integration. I used to be very selective of what I did with others. If I had an invite from friends and the activity didn't seem immediately interesting to me, I'd decline. I've since learned to say yes more (but not always) to invites and particularly consider ones that are more outside my comfort zone. This does however require a sacrifice of my individualism that is so heavily prized in western culture.

Curious, why does higher T cause hair loss if T is naturally higher in adolescence where there is less hair loss.
