I hear you, but the current state of affairs in Java (I know this isn't quite Java, but just for illustration) is more like: Dictionary<string, KeyValuePair<int, string>> contrivedExample = new Dictionary<>();

Agreed, better to use an IDE to insert the full type of a variable automatically so the code is readable in any environment afterwards. Inferred types feels like an invention for people who don’t like IDEs, that somehow forces everyone _els

Many IDEs can automatically insert the type of a variable when developing. This seems preferable: have one person do this one action once, rather than every person reading the code in the future having to do work to decode the type.

France is an interesting look at an alternate future where Nuclear was done properly. If world energy production was more like France we'd definitely be in better shape.

There basically _are_ no problems left, it's mainly economic and production volume now. None of those counter points points really hold up under scrutiny: 1) Renewable power _is_ clean. It is also becoming baseload and dispatachable wi

Great idea! Very smart to focus it on building profile pages for Instagram users, then it's a focused use case rather than the general "make a website." One suggestion: I found the whole term "Insta website" to be m

The price goes down over the first 3 years as well. Not sure why they do that exactly, but for a long time user like myself I'm happy they do!

Would anyone mind sharing what time series DB they use in production, and what for? I'm assuming most are used for metrics in addition to a standard SQL database, but interested to find out if that's accurate. Thanks!

by matt2000 7y ago
My guess is that at 5min resolution (288 data points per day), you're probably just better off going stock SQL. My understanding is that time series DBs start getting useful at higher write loads that standard SQL DBs aren't neces

Looks like fuel costs are really low, but maintenance and replacement component cost might be pretty significant: https://www.sciencedirect.com/science/article/pii/S036054421...

I'm both excited and skeptical. There was a similar demo in 2016 and then repeated claims that full self driving ("coast to coast with no interventions") was less than a year away. How is this different? Apparently people at

I've used Scaleway for one thing where I needed lots of cores and latency didn't matter, but I'm not sure I'd use them for much more. Heard a bunch of questionable things about their networking too, how has your experien

Would you call it a managed database, i.e. does it come with continuous backups and things like that?

Very cool, congrats on getting to this point. I have a few questions as a long time heroku user: - Can you scale up to more app server instances? - Where are your servers running? Based on location and the pricing progression, I'm gues

Strongly recommend Cloudflare in combination with some uptime monitoring service. Cloudflare gives you so many options on ways to mitigate attacks, and you get CDN and other services for free. Pretty great.

I'm in your category as well. An unfortunate side effect of this is that I think I'm kind of terrible at technical interviews though.
