Great, was not aware of that at all. Was quite flabbergasted at how so little (albeit very dense) code could generate such a lively scene without any use of textures etc.

And the best thing is the author shared it as a shader toy: https://www.shadertoy.com/view/WsSBzh

The only place I know where a lot of houses are made of wood are Scandinavia and North America. In the rest or Europe most houses are made of bricks and/or concrete as far as I can tell.

How long do they last on a battery? I have the older version https://www.aliexpress.com/item/32845863956.html which runs on a about 9 months on a rechargeable AAA penlite. But I could use a few more and these new ones are a lot cheaper.

Ubiquity definitely also has a lot of issues. Unstable firmware's, non-responsive support on their forums, deprecating working products... Like you can't self host their DVR software, but the newest versions don't run on older hardware so you have to buy a new hardware to get new software.

Also their product lines Edge and Unifi don't work together, so you can't manage an EdgeRouter with Unifi or vice versa, for which I don't think there is a technical reason, just commercial.

Hardware wise they also have made strange choices regarding PoE, don't assume your Unifi PoE switch will work with your Unifi PoE device (really double check the versions, voltages, passive/active)

So lots to complain, though I think it is still the most accessible pro-sumer networking stuff.

An now just wait until Troy discovers https://esphome.io/

Program your IoT devices to function independent of the mothership (HA), use whatever sensor you fancy (as long as it is in the growing https://esphome.io/#sensor-components list), and of course soldering is required.

Nice idea. I would love to know how the fretboard visualizer works and looks like, but am too lazy to install and run the tool. Could you add an animated gif or at least some screenshots?

they are sometimes, but actually that is rather pointless. The energy wasted by braking is quite negligible compared to riding at reasonable speed with some headwind. better invest in a better battery or make the bike cheaper than regenerative braking. At least from my perspective with an electric cargo bike an normal e-bike, and a super expensive speed-pedelc (45km/h) Stromer bike with regenerative braking. Because of the regenerative braking my fastest bike is actually the slowest if the battery is dead. Also it is almost impossible to go faster than the speed limit as the bike actively brakes whenever you go over 48 km/h. That's why I am selling it.

Anyone else chuckle at the term "laser-induced mortality"?

I'm personally a great fan of esphome.io. Use simple yaml files to configure a firmware built exactly to your whishes for various esp32 and esp8266 variants. Includes support for a ton of peripherals.

The list of supported hardware is actually a great place to look for which sensors are commonly used for for e.g. air quality, c02, temperature, humidity, power monitoring etc. Almost all supported sensors are available for a few bucks on aliexpress or equivalents.

You can connect the result to home assistant, but you can also move all or some of the logic to the board. So your light still switches on when motion is detected when your WiFi or the server is down. But if motion is detected at certain hours, you'll get a notification via home assistant

This is coincidentally also how I describe my job: I help when it doesn't fit in excel anymore.

Much easier for people to understand than shorter than civil engineer turned software developer in an engineering firm where I do data management, automation and application development for (mostly internal) clients to streamline business and engineering processes.

Exactly, jsonschema allows one to describe exactly how the json should look like including inter field validation. And with tools like reactjsonschemaform you can generate a ui on top of it for free.

please enlighten us non-Italians

It is also great for string all dependencies for development together in a docker-compose file. On any machine you just have to git clone and open vscode in the container and you are good to go. Even if you require a particular version of postgresql, some compiler version or a complete Kafka cluster; everything can be configured in a Dockerfile/docker-compose file and stored with the code. No more pages long readme's of how to get all dependencies set up just right. Especially when often switching between projects and machines this is a godsend. And for onboarding it is so easy to get someone a fully configured working environment.

sounds like my company: any windows machine is infested with a dozen or so McAffee things that make it unworkably slow. But none of the drones that role out McAffee has ever touched linux or osx, they prefer to leave that alone. So even though I actually prefer windows as a desktop OS, I mostly worked on a MacBook (until the pandemic, now I WFH on a my personal windows machine). But since WSL2 is finally backported to whichever outdated windows my corporate laptop runs, it is actually quite usable with VSCOde/remote containers + docker

I think we as humanity will just keep on denying this is happening or that something can be done about it, until in a few (?) decades we'll agree that we're f*cked and that it is all to late and we must blame the people of the past for getting us there. That way we are never personally responsible, but can always look at someone else/some other time.

Pretty impressive battery for the price. Speed-pedelec bikes (electric assisted bikes capable of 45km/h, with <1kWh batteries) cost about the same.

And you need license (which you can get by taking an written exam, no actual driving skills required)

> De-duplication on ZFS is currently an uncertain bizzaro universe populated with misshapen horrors crawling along a broken landscape. It’s a world of extreme memory overhead for de-duplication tables, and potential lost data due to inherent conflicts with the CoW underpinnings. Please don’t use it, let anyone else use it, or even think about using it, ever.

Is this advice still valid?

So what this does is introduce a (configurable) buffer between chained async generators. So this does not introduce any kind of multi processor parallelism, just makes an async generator easily be able to wait on multiple iterations in parallel. So basically the need for queues is abstracted away, looks quite nice if your use case requires something like this

I wonder if there is potential for enough methane hydrate turning gaseous that it drives a top to bottom current, bringing warm surface water to greater depths and thus creating a runaway effect where the ocean would seem to be boiling violently from all the methane being released. I had a nightmare about this the other day after seeing the tundra pits, no idea if this is remotely feasible

And if you are willing to compromise on the lack of case and a smaller screen you can get them for as low as 6 bucks shipped. Look for the ttgo esp32 with usbc and integrated lipo charging circuit, can highly recommend them!

Thank you HN for pointing me to this! It still exists on the internet of 2020, innocent creative brilliance with a nice dose of humor, not spoiled by commercial interests. This almost feels like the internet of yore

This has been posted before, but the new thing is that the scale model has made a maiden flight: https://www.youtube.com/embed/XHFcLfSfJWQ

If you are wondering why the video didn't include the landing, the press release states it was a bit ruff. Probably means that it all but fully crashed.

There is a bug in the last level. This css works (the path collision detection allows it):

  .tower-group-1 {display: flex;}
  .tower-1-1 {}
  .tower-1-2 {}
  .tower-1-3 {align-self: center;}
  .tower-1-4 {order: -1;}
  .tower-1-5 {order: -1;}

That has already happened too with the 737 Max fiasco...

> It would be a bit like how carbon dating or production of low background steel changed after 1945 due to nuclear testing

I guess books published will be more useful than reddit rants (depending on the application)

Perhaps a job at a medium size non-tech company. There are plenty of problems that can be solved with small scale (web) apps everywhere, that don't need webscale levels of scalability, but are well suited for a single full stack developer

I also came up with the same analogy after reading both posts. Wasn't just lurking and when I later had a moment to post my brilliant analogy it was already posted. So if many of us thought of this independently, does that make it a better or worse analogy?
