Sami_Lehtinen··on Matrix.envs.net Is Shutting Down

Many don't have Matrix client installed.

Sami_Lehtinen··on Matrix.envs.net Is Shutting Down
Hello everyone,

I'd like to inform you about an important change at envs.net.

As many of you know, the Matrix service consumes a lot of resources. This has become increasingly problematic in recent months, as it's making operation more and more expensive.

For this reason, I've decided to discontinue the Matrix service.

The shutdown is planned for March 1, 2026, but no later than April 1, 2026.

Registration of new Matrix accounts has already been disabled.

I believe this timeframe is appropriate to give everyone enough time to migrate their Matrix account to another server.

At the same time, the entire envs.net infrastructure will be moved to a new, more cost-effective server to return closer to envs' original minimalist values.

In the future, chat for the envs project will again take place via IRC.

As before, we will be using the tildeverse IRC server:

• Server: irc.tilde.chat • Channel: #envs

Please respect this decision and refrain from sending private messages expecting justifications.

Thank you for your understanding and please accept our apologies for any inconvenience.

Best regards, Sven aka. ~creme

Sami_Lehtinen··on Serving 200M requests per day with a CGI-bin
For CGI endpoints that are called infrequently—daily, weekly, or even monthly—the script startup delay is negligible. Even a persistent process waiting to handle a request can have its memory swapped to disk by the OS under varying server load. When a request finally arrives, the delay from swapping that memory back in can negate any theoretical advantage over a cold-starting CGI script.

Of course you're using different accounts for personal versus work use?

Agreed, most of email servers and services are broken per RFC. I've blogged about this over and over again.

Sami_Lehtinen··on Tell HN: Hacker News now supports IPv6
Technically it's just 128 bits, it doesn't matter how you represent it. I've written this IPv4ES solution, which allows you to use 128 bit addresses using IPv4 format.

Sami_Lehtinen··on Tell HN: IPv6-only still pretty much unusable
I see this just as repetition of the 32 bit vs 64 bit operating systems. Why would anyone want to use 64 bit operating system? Instructions are longer, it requires more cache, RAM, disk space and so on, making performance worse. Nobody actually wants 64 bit systems. Endless problems with drivers, programs, etc.

Walkie Talkie mode, I've really waited for it. I've found it amazing how developers find it way too hard and complex to implement basic PTT features.
Sami_Lehtinen··on Mojeek Surpasses 5B Pages
DuckDuckGo did implement filters which is big part of the problem. Mojeek is also independent when DuckDuckGo is just cover on mostly Bing.
Sami_Lehtinen··on Who's Attacking My Server?
My servers currently ban in average 1200 individual addresses and around 20 /24 cidr network addresses, which is triggered after N individual addresses in a specific subnet size gets flagged. The amount of abuse traffic is ridiculous.
Sami_Lehtinen··on Why offer an Onion Address rather than just encourage browsing-over-Tor?
> “.onion” address demands that the person is using a TorBrowser

Actually this is not true. Tor runs as SOCKS5 proxy, and you can use any browser or application with it.

Mostly yes, but also Yandex, Wikipedia, etc. But for reference the https://mojeek.com is actually an independent search engine, with own index and crawler.
