Materialize https://materialize.io/ Incremental update/materialization of database views with joins and aggregates is super interesting. It enables listening to data changes, not just on a row level, but on a view level. It's an approach that may completely solve the problem of cache invalidation of relational data. Imagine a memcache server, except it now also guaranties consistency. In addition, being able to liste…

This looks great - I've been looking into debezium for a similar idea but they don't natively support views which makes sense from a technical pov but is rather limiting. There's a few blog posts on attaching metadata/creating an aggregate table but it involves the application creating that data which seems backwards.

Would be huge if materialize supports this out the box. I believe it's a very useful middle ground between CRUD overwriting data and eventsourcing. I still want my source of truth to be a rdbms, but downstream services could use data stream instead

I've wanted to try mobile programming for a while (I am a web dev). Is Flutter a good choice for a mobile beginner like me, who hasn't done any mobile programming at all?

I'd say yes, although learning dart maybe take a week or two in worst case. Flutter, as opposed to react native, is quite easy to set up. The declarative UI paradigm is nice.

one two weeks is not bad at all for a new language. Thank you for answering.

I hope Google doesn't lose interest in Flutter and shutter it.

Any thoughts on using Flutter for the web?

I'm going to try this out. I assumed the resolution of the Quest wasn't quite there to make coding in a virtual desktop comfortable. How has your experience been?

I use it every day. With wifi-direct there is zero lag. I work with 3 1440x900 virtual screens. It’s more than enough for coding and the convenience of multiple screens for free offsets the low resolution.

Did you try increasing internal texture resolution? It makes text crispier. The framerate will drop, but it's tolerable for this use case. I find it very useful. There are various resolutions supported, this is the highest where increase in quality should be most noticeable:

$ adb shell setprop debug.oculus.textureWidth 2048 && adb shell setprop debug.oculus.textureHeight 2048

You have to start application after this is executed. To go back to original, you can reboot device or run this:

$ adb shell setprop debug.oculus.textureWidth 1280 && adb shell setprop debug.oculus.textureHeight 720

> Lightning Network - A way to do micropayments, if it works, You can stop the tape right there. You know it doesn't and it can't.

Genuinely curious, what’s wrong with the lightning network?

For starters the whitepaper concludes that a 133mb base block size is needed for it to work at scale. Bitcoin currently has a 1mb block size limit, which it will never increase.

"Self-hosting apps is time consuming and error-prone. Keeping your system up-to-date and secure is a full-time job. Cloudron lets you focus on using the apps and not worry about system administration." neat, don't think I've seen something like this before!

It kind of just looks like a simplified version of CPanel which has been on every VPS for the last 20+ years.

Gaze tracking. I've used the dedicated gaze tracking sensors from Tobii and it's really natural and responsive. I think we're going to see a lot of touchless interaction become popular in the post-covid world.

How accurate are those sensors? I've often thought how nice it would be to get rid of the mouse and use sensors to figure out where exactly on my screen I'm looking.

Mouse-level accuracy requires a well-calibrated setup and the correct size monitor and sitting posture. If you want to do something like a Square POS checkout and need to distinguish a random visitor looking at 4 buttons, it would be pretty forgiving.

Doesn't Hasura or Postgraphile do this better? They give a GraphQL API over Postgres with support for subscriptions, along with authentication, authorization etc.

Can't help but laugh whenever I read about self driving cars predictions like this sorry. My GPS can hardly navigate most of the world I'm not really excited and if the only criteria of self driving car is self driving on a high way then color me uninterested. I don't think self driving cars will be able to traverse majority of the world's traffic anytime soon. The road is just too difficult to maintain for human fre…

Self driving cars don’t need to be 100% autonomous in all possible scenarios in order to be useful. Self-driving reliably on the highway? Hell yes I’d take that (just think of trucks - having a driver to the highway is so much cheaper than having someone drive it cross-country). Self driving reliably in a few major cities? Oh, you mean cheap robotic taxi?

I agree with you it's just as I said - it's not what we've been sold and autopilot on highway is kinda boring.
