rathel··on Jim Keller Resigns from Intel, Effective Immediately
Oh yeah. I have friends who work or have worked at Intel.

Management who runs this company are straight lunatics. The sheer amount of shelved projects, pointless reorgs, layoffs-for-show is staggering.

I do work in a corp, but thanks God our leadership is much more down-to-earth, even if I earn less money, I am able to retain relative sanity (due to my allergy to bullshit).

FYI: hashtags don't work on HN.
rathel··on Tell HN: Shutterstock is changing its commission structure
Stock photography has to catch up with lifestyle, technology, fashion, society, culture and architecture, among others. On top of that, stock sites sell news images as well.

So no, there always will be something to be photographed.

rathel··on The Economics of ASICs: At What Point Does a Custom SoC Become Viable? (2019)
Japanese companies seem to have a boner for custom ASICs. I never understood that. For example Roland uses custom chips [1] for their synthesizers and effects, where they could use almost any DSP on the market.

Likewise printer manufacturers go for a huge SoC where they could get an application processor that suits their needs and couple it with a specialized printer chip. [2]

What's the deal?

rathel··on StreetComplete asks questions, with answers used to improve OpenStreetMap data
OSM is a map first, not a business directory - although these do overlap. Admittedly, businesses without a marked presence are not de facto priority (as in: no explicit rule, but they don't get mapped first). Shops, restaurants and so on that are open to the public are more so.

Ultimately in a cooperative project like OSM you have to be able to somehow verify others' work - that's why there's "on the ground rule". https://wiki.openstreetmap.org/wiki/Verifiability

That said it's only a guideline, which is deviated from in some cases (like administrative boundaries). I guess some other proof could pass, if it was plausible enough.

rathel··on A list of FOSS apps for Android
From the description of G-Droid, an alternative client for F-Droid repo:

shows the web-site of the app even if it is 'only a README file on github'. F-Droid has removed many websites (not all though) of apps the team doesn't like. They also don't allow (as of now) to re-add these link to the websites. This has been done with dodgy explanations and only for apps that the F-Droid team particularly dislikes (to censor apps they don't like) and reduce the amount of download and users of these apps. Hint: if your app is affected and shows no website in F-Droid promote and encourage your users to use G-Droid.

What the hell?

rathel··on StreetComplete asks questions, with answers used to improve OpenStreetMap data
> It's pretty common for me to see a note from someone that's like a year old saying "this business isn't here any more". Indeed, it is not. I mean, I could add a picture (didn't realise that feature existed), but how would that help? It's a picture of a thing that's not there. Why not take the notes word for it when it was first posted a year ago?

"This place has gone or never existed" is a note from MAPS.ME generated by clicking such button in that app. But people sometimes missclick it. Or use it wrongly e.g. place exists but has slightly inaccurate position or name. Or use it on POIs they added themselves as a mistake (MAPS.ME allows adding/editing POI, but not deleting them)

If you solved as many notes as I did you would understand ;) I think that photographing something that's not there is still a valid thing. I try never to trust notes blindly, and when possible corroborate it with outside sources (no copying of Google Maps allowed, though).

> If this is some multi-verification thing, there must be a better way to present that?

Notes, their usage, and resolving are pretty free-form.

rathel··on StreetComplete asks questions, with answers used to improve OpenStreetMap data
For anybody who uses StreetComplete - whenever you select "Can't answer" to a quest, an OSM Note [1] (ie. error report) is made. Please consider attaching a photo whenever you can so other OSM mappers can resolve the issue without the need to verify the place in-person themselves.

Another thing that's super cool is that StreetComplete allows you to answer other OSM Notes (made also or rather mostly outside of StreetComplete) with photos. There are many countries with a deluge of unsolved Notes [2] and a photographic proof allows people to resolve them remotely. Just remember to turn on displaying all notes, not only questions, in the app settings.

rathel··on Nintendo has reportedly suffered a significant legacy console leak
Well, they'll always oversell the damage, but realistically, not much impact to their bottom line. They do release remasters and ports, but I'd be hard pressed to see it being a significant loss in the grand scheme of things for a company that doesn't need to subsidize hardware with software. Like: people would buy a hypothetical N64 mini regardless of 3rd party emulators available. Or buy old games on the Virtual Console or however it's now called on the Switch.

From enthusiast perspective - it's a boon for preservation purposes.

rathel··on Heat Pump Water Heaters
Yay for another descriptively named controls on an appliance. What did people designing this think? I know it's probably in the manual. But there are people from whom you can't expect reading the instructions - not because of "fuck the manual" attitude - like guests who live only temporarily.

Would a more descriptive label save them $0.01 on ink or what?

rathel··on Show HN: Fast Anomaly Detection in Graphs [pdf]
Thank you for the explanation.

I'm looking forward to M-Stream for multi-dimensional data - but I have one question for that. Is there some preferred approach for selecting features in multi-dimensional anomaly detection?

Because I wonder if given enough dimensions, everything would be anomalous. Kind of like p-hacking works (at p=0.05 one of twenty hypotheses is falsely accepted just by sheer luck).

rathel··on Show HN: Fast Anomaly Detection in Graphs [pdf]
Nice! I like there's a ready-to-use command line utility.

I think it'd benefit from a refactor to actually allow real-time streaming from stdin.

Do you have any hints how to choose timestamp units and how that affects parameters I should choose?

rathel··on All models are wrong, but some are completely wrong
> We can't even predict many of these subsystems with any degree of accuracy so we are hopelessly inaccurate at the higher level.

Or do we? This sounds like a Fermi problem

I may be wrong, though.

rathel··on Show HN: Business Name Generator Powered by AI
Apparently it didn't take long for an example to appear:

https://news.ycombinator.com/item?id=22725529

Based on name you'd think this library is for fuzzing? No, it's for fuzzy string matching. A "y" at the end would have disambiguated that.

Well, maybe not entirely, because there's still fuzzy logic, but that' 2 possibilities down from 3.

rathel··on Show HN: Business Name Generator Powered by AI
Kind of tangential, but even here on HN you can see how awkward people get with naming their projects/products. Either "stealing" an already established name from a completely different field or something so generic it's hardly searchable on the interwebs.
rathel··on Open Food Facts
In 2012 OpenStreetMap switched from CC-BY-SA to Open Database Licence.

I think the most important is the provision that "produced works" need only to attribute the authors, and if you don't modify the source database then the license is non-viral.

rathel··on Counterintuitive things that helped me fix my insomnia
Yes, obviously doses this high are prescription only. Should have mentioned that.

Guess I have to trust my doctor, who mentioned this is a saturation dose, and later on I will switch to lower doses available over-the-counter.

rathel··on Counterintuitive things that helped me fix my insomnia
Consider checking your D3 vitamin metabolite levels in blood. I had trouble falling asleep, had single digits of 25(OH) D3 concentration (The norm is 20+ ng/ml).

For now I was prescribed 20k IU of vitamin D3 twice a week. Other things that helped - no caffeine after 3-4 pm and a cup of raspberry-hibiscus tea in the evening (It's very relaxing).
