dan353hehe··on Hetzner raises prices while significantly lowering bandwidth (US)
Yep. Same thing happened to me. I was not able to get my account working. Ever.

I have all my stuff on vultr now.

dan353hehe··on Meteorite 200 times larger than one that killed dinosaurs reset early life
Thank you!

I have been trying to remember the name for that comic for years, and no amount of searching has ever yielded anything.

dan353hehe··on Effect of a giant meteorite impact on Paleoarchean environment and life
> Drabon and her colleagues went in search of evidence of ancient major impacts in a remote area south of Kruger National Park in South Africa. There they sought out rocky outcrops containing a layer of spherules – molten droplets formed following a major meteorite impact that rained down over huge swathes of the planet. There are eight such spherule bands in this area, each preserving an ancient impact event.

> While the impact crater itself is long gone, analysis of rocks from 3.26 billion years ago tells a tale of planetary devastation. The layer of spherules from this huge impact was 15 to 20cm thick in places, compared with less than a centimetre for the famed dinosaur-killing meteorite, says Drabon.

dan353hehe··on Since the '60s, Ford has stored cars underground in a Kansas City cave
I remember seeing something about that a few years ago. Super strange they never were found.

Cave Johnson probably still has them doing some important science underground somewhere.

dan353hehe··on Mac Mini with M4 Pro is the fastest Mac ever benchmarked
This was a surprise for me as well. I have two EPYC 9754 in a dual socket server, so 256 cores, and the test did not perform as well as I expected it too. It didn’t even load up all the cores, which is what I was needing to do.

I ended up using something else to generate the load I needed, but I can’t remember exactly what. I think it might have been a Monero benchmarking tool?

dan353hehe··on Project Euler #912: Where are the Odds?
One that I like to suggest, which covers more terminal and Linux skills then programming, is https://overthewire.org/wargames/
dan353hehe··on Geothermal Energy Could Outperform Nuclear Power
It’s not a stupid question. In most threads on geothermal energy this does come up and a lot of other people have answered it though.

The short answer is that there is so much heat in the massive amount of melted rocks and metal under our feet that we could never possibly cause any sort of significant cooling of the earth.

dan353hehe··on First water car is already a reality: 1000km of autonomy and the end of gasoline
> This membrane acts like an electrolytic cell, using electricity to break down the water molecules into their composite elements. The hydrogen produced from the reaction is then fed into the vehicle’s fuel cell.

You are exactly right. It’s a fuel cell car.

dan353hehe··on How to avoid losing items? Holding pens
That’s simple enough. Just get a second tote for holding your first tote! Then you just have to keep track of the second one to be able to locate the first one.
dan353hehe··on Pongamia trees grow where citrus once flourished
All very valid points. I live in the dessert, and we have mesquite trees here everywhere. They also produce a bean in a pod which I learned several years ago is edible!

I ordered some flour and put it in bread and other things. It’s a sweet flour that tastes like a very interesting chocolate.

It’s just hard to harvest, and to mill, and not a lot of people are willing to eat different things.

But the tree thrives on less then 8 inches of rain a year.

dan353hehe··on "Doors" in Solaris: Lightweight RPC Using File Descriptors (1996)
I did some debugging about 8 years ago in SmartOS. There were some processing that were running for way too long without using the cpu. I ended up using kdbg to trace where the processes were hung. I had to jump between different processes to trace the door calls. There was no unified stack in one process that spanned multiple address spaces, and the calling threads were paused.

So, yes. The documentation in right, the calling thread is paused while a different one is used one the other side of the door.

dan353hehe··on Not an iPad Pro Review: Why iPadOS Still Doesn't Get the Basics Right
This is exactly what I did. I got 2 refurbished iPads for about $100 bucks a piece almost 3 years ago. Works great, and the kids don’t fight over who’s turn it is.
dan353hehe··on Ask HN: Got a /22, cool things to do with it?
Well if it’s for learning, you can rent vms from hosting providers. That’s a fairly inexpensive way to learn about BGP with a global “toy” CDN.

I have a small ipv6 subnet I purchased for just this purpose. It was interesting setting everything up in multiple locations and seeing traffic routing around as I turned machines on and off.

I also set up my machines as a reverse proxy of a sort, a small fake CDN, and experimented with caching at different locations and moving content around.

I would have gotten a bit more serious about it, but I’m still on the waiting list for an ipv4 subnet after 2 years. And pretty sure it would be too expensive now. Would have to check though.

dan353hehe··on Lichess: Block Ads and Trackers
Is it also unethical to not read the ads in a newspaper? Or to not watch the commercials on TV?
dan353hehe··on Utah officials sued over failure to save Great Salt Lake
You forgot to mention all the superfund sites that have only recently been cleaned up. Some of which aren’t done yet.

These sites are all on the Jordan river, and it’s tributaries, which empty into the great salt lake.

https://en.wikipedia.org/wiki/Jordan_River_(Utah)#Pollution

I used to live within walking distance of the Jordan river, in Rose Park by the fairgrounds. I remember getting warned not to play in it.

dan353hehe··on 1-Bit Hokusai’s ”The Great Wave”
I have astigmatism. I had the same issue with grids, certain fonts with lots of vertical lines, and other regular high contrast repeating patterns.

Got some glasses a few years ago for the first time from an optometrist, and now it doesn’t bother me anymore.

So I would recommend getting it checked out.

dan353hehe··on Orbis Wheel Powered or Unpowered Ring-Driven Wheel
I dug through some of the videos they have put out, and the wheels are activated by reading the ODBII port on the car. Which means that they monitor the stock gas and break pedals to determine when to move.

You can potentially add a pair to your gas car and turn it into a hybrid, or add 4 and replace the gas engine completely.

dan353hehe··on Lucid announces new lower priced sedans
I believe the OP is saying that the service to their house is underpowered. Meaning the wire conductors that run from their house aren’t rated for a lot of current.

For example my house is only rated for 120 Amps total, and to upgrade that I would have to contact the electrical company and have them install new wires to my house.

dan353hehe··on Level responds to lock picker opening its $330 Apple Store lock in seconds
I think everyone is missing point on this. This is actually a feature! Loose your key? Loose your iphone? Loose your Apple Watch? No worries just ask your friendly neighborhood door to door sales person to open your door for you!

You will literally never be locked out again! /s

Jokes aside it is pretty shameful to sell a poorly made product, and then justify it by saying that it’s still safer then leaving your door unlocked. $330.

dan353hehe··on Ask HN: Apps that are built with Git as the back end?
Also spent a few minutes browsing around and found https://github.com/creationix/tedit, a web based editor that reads and writes directly to git (I think).

Like I said Tim has quite a few projects that interact directly with git.

dan353hehe··on Ask HN: Apps that are built with Git as the back end?
Tim Caswell has several projects that interact directly with git. He has a few websites served directly from a bare git repo powered by https://github.com/creationix/wheaty. Another project that uses git as a storage medium is a package server for the node.js API implemented in Lua: https://github.com/luvit/lit.

Both serve files from a git repository, and lit will actually write to the repository. There are several others that Tim has built over the years, but those are the two that I am familiar with.

For anyone geoblocked

dan353hehe··on JWST: Identification of carbon dioxide in an exoplanet atmosphere
Wait, the metal talks? And it thinks with its metal?
dan353hehe··on The world map that reboots your brain
The boosters can only be so wide because of the size of road and rails. The widths of which were based on wagons, which could have been pulled by two horses side by side.
dan353hehe··on Quaise Energy is working to create geothermal wells
A similar question was asked in a another geothermal post. https://news.ycombinator.com/item?id=32134418

The tldr being that there is sufficient heat and we don’t need to worry about running out even if we tapped into a significant portion of it.

dan353hehe··on LiteFS a FUSE-based file system for replicating SQLite
I’m curious, was there a specific reason that FUSE was used instead of the FVS layer inside to SQLite itself? I realize that it would mean that a custom module would have to be loaded, and maybe that was undesirable. Full disclosure I have not read the link yet as I am a little pressed for time, but I will later tonight when I have time. If it’s mentioned in the readme, feel free to ignore me :) I ask because I have been building a VFS for SQLite to handle multiple distributed writers and replicating data blocks around to different places.
dan353hehe··on Start all of your commands with a comma (2009)
I do basically the same thing with any aliases or commands that I have just for me. Except I prefix with _ (an underscore.) Having some sort of prefix is extremely nice as it ensures you never override a built-in on accident, AND it makes it easy to tab complete just the ones that you want.

For example I have ‘_f’ aliased to a fuzzy find command that will launch vim on the selected files, and a different one for launching sql clients to various servers etc.

As a prefix, commas work great!

dan353hehe··on The Apple M1, ARM/x86 Linux Virtualization, and Boinc (2021)
I’ve been using an iPad Pro with the blink shell app for almost a whole year now. I just use mosh to connect to my homelab development environment, and it works really great!

But yeah, if work doesn’t quite fit with just needing a terminal, and a few web sites or iOS apps, then it’s not going to work.
