> it of course will still have identity in being a unique structure in memory

No, it will not. The design allows multiple objects to share one structure in memory across multiple records, or not have such a structure at all (see Scalarization in the article).

- english X -> russian doesn't have 1 letter equivalent, usually КС or ИКС used

New comment by oddx in "Principles for building and scaling feature flag systems"

oddx — Sun, 24 Sep 2023 09:34:47 +0000

I dedicated a day to evaluating feature flag software based on specific criteria:

    - Must support multiple SDKs, including Java and Ruby.
    - Should be self-hosted with PostgreSQL database support.
    - Needs to enable remote configuration for arbitrary values (not just feature flags). I don't run two separate services for this.
    - Should offer some UI functionality.
    - it should cache flag values locally and, ideally, provide live data updates (though pooling is acceptable).

Here are the four options that met these basic criteria and underwent detailed evaluation:

    - Unleash: Impressive and powerful, but its UI is more complex than needed, and it lacks remote configuration.
    - Flagsmith: Offers remote configuration but appears less polished with some features not working smoothly; Java SDK error reporting needs improvement.
    - Flipt: Simple and elegant, but lacks remote configuration and local caching for Java SDK.
    - FeatureHub: Offers fewer features than Unleash and Flagsmith; its Java API seems somewhat enterprisly but supports remote configuration and live data updates.

Currently, I'm leaning towards FeatureHub. If remote configuration isn't necessary, Unleash offers more features, and if simplicity is key and local caching isn't needed, Flipt is an attractive option.

But caching doesn't required here. Hash.new calls block only if value isn't initialialized.

> That's cool and all, except everyone in that country had 2 sim cards with 2 numbers.

This is not true. Some people have multiple SIM cards, but it is not even remotely close to "everyone". Based on numbers that I found, multiple SIMs have around 30% people.

Try to use Telegram for communication, it might work. It's not full internet shutdown, some programs like Telegram or VPN Psiphon, Tachyon work from time to time.

New comment by oddx in "Eliminating cold starts with Cloudflare Workers"

oddx — Fri, 31 Jul 2020 21:43:31 +0000

It's not clear what exactly they mean by cold start. I just ran a simple test with a worker returning hardcoded html without external requests (on a free plan):

1. First run: time_starttransfer: 0.507267s

2. Second run: time_starttransfer: 0.035244s

So it looks like at least some parts of the cold start taking much longer and aren't eliminated.

This is not true, you need one schengen visa even if your country doesn't have visa agreement with EU (my country doesn't have).

New comment by oddx in "Ask HN: Why are cheaper hosting services like OVH not very popular?"

oddx — Sun, 16 Sep 2018 17:37:19 +0000

I don't have answer to you question, just a few notes about another low cost proder - Hetzner: * They have RAID by default * They have private network included now (vSwitch)

Drawbacks from my expirience: * You have to monitor hardware by yourself (SMART, CPU and HDD temperature) and requests checks if you suspect hardware failure * Decreased flexibility (curretly Hetzner have limited cloud support, but it's very limited). Probably doesn't matter for most startups. * More manual work for administration (provided services are more low level)

Belarus is may be dictatorship, but it's for sure not totalitarian. And if you think that nacist Latvia is open liberal democracy you bought into propaganda.

Estonia, Latvia and Lithuania were parts of Russia for 300 years with small omissions. It is longer than the time of existence of the United States. So they have a lot cultural and ethnical similarity with Russia. But yes, they try to ignore it officially.

I guess it was just:

- login to server

- make dump of all threads stack traces

- see that something like Regexp.match present in all stacks

- find function that called this regexp.
