I'm using snapdrop.net for that. It requires a server, but clients only need to open a webpage, so it's easier after initial setup. I run mine on Synology server.

Too bad it seems to not be mantained anymore

I picked up Svelte to build my first non-trivial app, which is flying navigation aid for hot air balloon pilots[1].

Svelte is much, much easier to grasp than React or Vue, especially when it comes to state management. I like that it’s super lean and it never confuses me what’s native Javascript and what’s the framework (pretty important for a non-developer me). And I love not having to write huge amounts of boilerplate code.

Reactivity sometimes gets more complicated than advertised on docs. For example, I have a bunch of functions where I manipulate an object and need to reassign it to itself (feature = feature) to trigger refresh on reactivity block. Sometimes it’s easy to miss and not know why reactive statements are not being updated.

Also, docs are pretty barebones. For comparison, I think Vue docs are explaining details in better and clearer way.

people in the comments have no idea it's a deepfake. Without knowing beforehand, I wouldn't recognize it too.

Vector map of the whole Earth in PMTiles format is only ~65GB[1] and doesn't need any server or database - it's just a static file which you can host wherever you want.

bdon (author of PMTiles) already commented on this thread. I recommend taking a look at https://protomaps.com/docs - compared to this, raster tile servers sound like ancient technology.

I did different setups over time, but currently settled on forwardemail.net for incoming catch-all custom domain and iCloud+ SMTP servers for sending.

40 people web startup. Currently Metabase as main BI tool, but I'm thinking about introducing a tool like hex.tech. IMO classic BI and dashboarding is inflexible and future lies somewhere else.

Backend is Bigquery + dbt. I highly recommend Bigquery if you are on GSuite and use Sheets. You can create views or tables in bq and have them included in sheets, always up to date. With dbt you can have them tested and be sure data is always correct.

Ask HN: Salary discussions – numbers are before or after taxes?

pkalinowski — Wed, 03 Nov 2021 11:42:28 +0000

Every time I'm reading discussion on salaries I'm not really sure what number people are actually talking about.

Is it net or gross? Before or after income taxes?

So advertising works? If it didn't, those buying ads would not take the pepsi market share

Man, this is perfect example of why most open source software has no chance to compete with commercial one.

One day I wanted to improve getting started documentation in open source f.lux alternative for linux, because it didn't work for me in Ubuntu without any visible error. I found the solution investigating terminal logs and did a 5 point write up "How to setup on Ubuntu".

Readme pull request got denied because "only one point applies to Ubuntu" (others were applicable to other distributions, too). Somebody even commented few months later that he found my pull request and it helped him make it work on his machine.

This mostly made me stop contributing to other projects.

VR gamedev is pretty exciting for me. There are almost no conventions or good practices, everybody is winging it. It's very greenfield and you work with your own hands and body.

Why single data scientist should be responsible for obtaining data from 2000 stores? Data at scale requires people at scale. Data engineers would do this job.

I wonder why it seems nobody wants to use Hugo. Smashing Magazine appears to be happy with it and they tooted about their experience with Hugo multiple times.

Instead, everyone chooses Gatsby, Next or another javascript based framework of this week.

Putting advertising outside of marketing is not a nuance.

Advertising is part of marketing.

In Europe, giving employee less time than it's needed to complete a task is called mobbing.
