Không thể kết nối máy chủ qua Websocket bằng Nginx Proxy Manager. Tác giả thiết lập đúng cấu hình Websocket (proxy_set_header Upgrade, Connection) nhưng vẫn bị timeout tại ws://talker.srv:8000/_event.

Just finished porting *another* of my shell scripts to Ruby. Moving from Linux to BSD has had some surprises and this is one of them:

People make a big deal about writing portable POSIX shell scripts, but it's pretty rare to find a platform that doesn't have, e.g. Bash. No, the problem has been all of the *other* standard utilities - it turns out I was depending on non-POSIX features in the core utils all over the place without realizing it!

I really like personal homepages and have quite a list of them bookmarked. I'll post one every week unless I fall behind this schedule. 😉 So here's Cool Personal Homepages #CPHP Vol. 59: "fastestcode.org" https://fastestcode.org/

Jag använder Macdatorer och har så gjort sen Macintosh Plus kom i slutet på 1980-talet. De är lättanvända, funkar alltid och de program jag behöver finns. Men Apple har länge också varit ett av de stora US-amerikanska techbolagen men inte så länge. Då var det helt dominerande företaget IBM.

@fbfortune Great tip!

In #ksh / #ksh93, you can just type ‘r + Enter’ and it also immediately pulls up the last command and runs it. It’s an alias for ‘hist - s’ or ‘fc -s’

In #bash or #zsh, if ‘!! + Enter’ is only expanding the previous command but not executing, it’s because histverify is on. To turn it off, add this to your ~/.bashrc:

shopt -u histverify

——————

shopt = shell options command
-u = unset

System Administration, Week 1: UNIX History

We're borrowing this video from our "Advanced Programming in the UNIX Environment" class to give a brief summary of the history of the UNIX family of operating systems.

The `vi` editor, a staple of UNIX-like systems, was first released in 1976 as part of the BSD. What are your favorite `vi`/`vim` tricks?

I regularly use the `gq` command in vim to clean up and format text blocks.

The /tmp directory, a temporary file storage area, has been a part of UNIX-like systems since the earliest days.

What's the weirdest thing you've ever found in /tmp?

@pixelate Hi, thank you for your feedback on accessibility and open source technologies. I always read your posts with great interest in order to improve the accessibility of FreeBSD, a UNIX and open source operating system.

At the FreeBSD Developer Summit in Dublin 2024, I showed other developers (using simulators) the challenges faced by color-blind, low-vision, and blind users. The @FreeBSDFoundation is currently sponsoring the "Vision Accessibility" project to improve accessibility for users with visual impairments.

At the Developer Summit in Zagreb 2025, I presented the new accessibility handbook https://docs.freebsd.org/en/books/accessibility/ focused on the assistive technologies currently available in the system, including practical examples to help developers better understand these challenges.

I am in contact with organizations supporting people with low vision, blindness, and deafblindness to implement Braille display subsystem for FreeBSD and to develop interfaces specifically designed to be used with screen readers.

Any feedback or suggestions are very welcome.
