We observe 200+ (can’t say closer number) purchases per second for single SKU with good marketing and price.

The other thing that bothers me - why not real stable, but maybe „too old, medieval” solution with Redis as the main source of through - without any sync with SQL at all in terms of stock… it worked in my previous job with much higher traffic (1000s/s). Yup, we ended up with app-side sharding, but it was stupid-simple.

You new to the world, right? ClickHouse proven being a beast for analytics, tracing and even some basic metrics storage (VM won of course, but still CH is probably 2nd or 3rd)

It’s still a thing in big corps. We have all business nanoservices (I can’t call them micro) at JVM (moving to Kotlin from Java) and any try using Go is silently killed by those JVM talibans.

I wonder if no one really thought there about rewrite that will still connect with all old dependencies with old protocols, but also will expose new kind of API that can be used by next rewritten block.

We also had mainframe, we used Oracle. It turned out that casual server is also reliable in long term and we restarted them only for upgrades of OS. Of course moving to some distributed, fault tolerant option also feels like good direction, but instead not-doing the perfect rewrite at once you can do it two/three step migration. Costs nowadays? You already fixed that.

I would love to see some blog posts and/or videos about this!

While reading all about cameras and other sensor I would try to use distance-driven sensors every where. Standing pin vs laying one have enough height difference to not mislead even simple distance echo-based sensor. Other techs I see more reliable are LIDARs, because they don't require lighting. Pure camera should have enough light to see the pins (or you have to do some IR based markings and IR camera) or you can't make the space darker for events etc.

So IIUC no one really worked on that in „professional” or rather university world since then?

Garmin will survive a year or more easily, because in Europe there is a big group of people who belive in Garmin even more than people belived in Apple (this group is still huge and strong, but the company itself does everything it can to change it).

The real competition is Apple Watch and for sport-intensive application Garmin wins because of battery and simplicity of usage in harder conditions.

As a scammed customer - this was inevitable. They promised great improvements model over model and didn't deliver.

I bought model 9 and since beginning it overheats, randomly stops recording or just shuts down. There were promises to fix this with firmware updates - didn't happen.

You meant - awful knocking combustion in the first, main animation? I never catches any real bug is those great posts, but this one, especially as first animation on the page - weird.

How hard you have to work to break scroll on web page? Nice article, but going through it was a technical nightmare.

Can we stop adding unnecessary JS to website to stop global warming by calculating AND ALTERING SCROLL?

He left for a break, returned and there was no second break or anything.

I don't want to spam it in repo, so leaving it here: he is kind of a hero doing this work and I (hopefully we) am very grateful for his contribution to this world.

I like using Go for many reasons, but exactly this one is making me sad every time. I can’t accept interface and be sure it’s non-nil at the same time. I think this is a flaw and it’s just a shame.

Nice work from DO marketing team! Prices are completely not comparable and Hetzner was fighting scammers and kiddies, because low prices worked like a magnet for those.

Russian spies? WOW, the earth got really flat these days. Seeing what US is doing with citizens and private companies I would love some Russian spy to be interested in exactly mine, boring passport.

ACTUALLY xD Transferring power from gym bicycles is one of the smartest things. But they probably won’t even be enough for the AC to run - still a lot of power and heat lost.

I think it’s Apple motto since 2011: „Never care about quality again”. I still can't believe Rosetta was delivered and works like that.

Maybe it’s time for Anthropic to move to some other place? Every news about next blockade for the company (including threats from gov in the near past) is just making US look… bad?

Even if this is ad only - are we really ready for a rug pull from Anthropic? Maybe I’m completely unaware in this tools space, but I feel like it’s last tool that’s worth (and not pricey)…
