Oh, I agree on this. People were never going to accept, nor IMO should they have, a massive reduction in their living standards. New technology is the way to make people's lives better while also reducing global warming. I just got bac

Humans can be trusted to do the right thing, once all other possibilities have been exhausted.

Also interested in this - the Apple Watch for Kids setup seems a possibility, but it's only available in certain countries

This is dependent on the database you are using - if it's a key-sharded distributed database, you want to have insertions evenly spread across the key space in order to avoid having all the inserts go into a single shard (which could

Not quite any - in CockroachDB, all schema changes are non-blocking: https://www.cockroachlabs.com/docs/stable/online-schema-chan... . Yugabyte seems to be getting there with them also. Still risks involved in

That's kinda the point though isn't it? DownDetector is showing an early indication of a major outage in both of your examples. The issue may not be caused by the indicated service, but it's still a useful information source

We saw a big spike in latency and failures on the Google OAuth apis starting at the same time (15:21 UTC)

A single report on there is useless. A sudden flood of reports is a good sign that something interesting is happening.

It has false positives and noise for sure, but it's also very sensitive and shows issues very quickly. I wouldn't trust it as a single source, but in a case like this where our internal monitoring shows a spike of issues with the

Your general point definitely stands - there is a pretty nice third party solution for google workspace though: https://github.com/GAM-team/GAM

I guess the problem there is pretty fundamental - in reality you'd be tensing muscles and shifting your weight etc before the snappy movement, but the game only knows that you want to move when you move the stick or push a button - so

It does seem like there would be a clean boundary between each school district, but actually there's plenty of sharing and collaboration on Kami that happens with users between districts, teachers and students move schools, parents can

We moved took a large working PostgreSQL app and switched it over to CRDB and that doesn't match my experience. Our existing schemas and query patterns moved over nicely - latency for small indexed reads and writes did increase from ~1

They would have to have many shards per city to keep up with the level of write traffic though. And what happens when a user from SFBA goes down to LA?

Clickhouse is a totally different use case - Cockroach is OLTP, Clickhouse is OLAP. We use both Cockroach and Clickhouse at scale and they are both great but not competing products - Cockroach is great for the types of reads and writes you

by jordanthoms 3y ago
Sharding is anything but simple. A single shard per region wouldn't have enough write capacity so they'd have to be managing likely 100+ shards in each region - you'd have to build a lot of infrastructure to automate setting

These are also good points you've raised. On scaling, yeah a single postgres server can handle a lot. For us we were well past the million user mark before running into serious issues. However, a lot of how we were able to keep postgre

This is an interesting project, but I'd be unlikely to use it, for a couple of reasons: - In my experience the performance of the stateful DB server has been the biggest bottleneck when scaling - it's much easier to scale the stat

Interesting - after the initial load it's substantially slower for me

If you want something which runs on the Raspberry PI and can do airplay/DLNA etc to a USB DAC without any hacks, try RoPieee XL: https://ropieee.org/xl/

Quite a few databases support time travel queries, in particular Oracle has for years and CockroachDB has them also. We can query the state of a table as it was at any point in the last 72hrs.

We switched to CockroachDB for some of our most heavily loaded tables a few years ago - and the scalability and operational simplicity has been great. I don’t have a like for like benchmark, but at least for writes - we’re running with 5 r

Yes, it’s removed on newer models, though not across all the products yet

It does exist, where laws allow for it - in NZ we have Snowball effect which does this [1]. As others have said though, when there's so much early stage capital around and you could instead raise from a few angels or a early-stage VC (

I guess it's all relative, our largest cluster scales up to around 3000 VCPU and there's plenty of much larger ones out there. You might be able to get better utilisation of your VMs by running a smaller number with more cores on

Is this zero-downtime? pg_upgrade with the link option is pretty fast, usually only taking a few minutes even with our >10TB database, but it does require taking the server down while it's running which is a major issue for many mod

We had less local restrictions than most other countries until delta hit 4 months ago - since then we've had a 3-month lockdown in our largest city and huge impact to small businesses, and we still have citizens locked out of the count

I ran a Asus ac-68u at home at home for years and was generally happy, but the speed bump from upgrading to a ax-86u has actually been very substantial even for ac devices. BTW I’m using a mikrotik router, but I’m not sold on Ubiquiti for h

Did you try with a PWA? Discoverability can be hard vs having an App Store listing but I wonder if that would satisfy your user-base if you made it into a nice experience
