weirdr.net is a Fediverse instance that uses the ActivityPub protocol. In other words, users at this host can communicate with people that use software like Mastodon, Pleroma, Friendica, etc. all around the world.
This server runs the snac software and there is no automatic sign-up process.

Who's got a preference for an RS232->Wifi/Telnet project and what is it? I have an ESP32 (and a bunch of 8266), a MAX232c or whatever. I want a device I can plug into a serial console and telnet (SSH would be great, but telnet is okay) anywhere, and there seems to be quite a few projects out there but none with an idiots guide, and seemingly none I can just buy...
I'd boost it (the blog is federated - @ltning), but @writefreely doesn't render nicely for some reason.

First thing at Home: trying my new #vectrex game “Hera Primera”.
It is boxed and comes with an overlay and a cartridge 🥰

mTCP NetDrive users ... the read-ahead version is ready for testing. I'm looking for your feedback on how well it works in your environment. See the announcement here for download links: https://groups.google.com/g/mtcp/c/ktDzPuWd1xw (no sign-in required)
Next up ... I know how I'm going to make writes faster too. With just a little more code in the driver.
NetDrive with read-ahead caching, running on a VM to a local server and to a server 50ms away. A 4KB read-ahead cache results in a 3x speedup locally and nearly a 5x speedup on the remote server.
Real hardware results depend on the speed of the hardware. Slow machines don't benefit much when connected to local servers, but they still get the full benefit on remote connections.
I wasn't aware of the ads PC Connection made in the 80s and 90s with raccoons, but they're definitely great, and this is an excellent write-up on them: https://technologizer.com/home/2025/04/22/pc-connection-ads-raccoons
After some delay I did an update of #lib16 (a tiny helper library for #OpenWatcom 16-bit DOS programs).
https://github.com/SuperIlu/lib16
This time I added #Lua to the mix (example prj04). You can now write graphical scripts using Lua on #MSDOS. I also included the regular lua.exe and luac.exe binaries. This is compiled for i386/387 upwards...
And this is where real hardware asserts itself ...
Using a 4KB read-ahead cache on the DOS side in a VM gave a 5x speedup, which was great and expected; you ask for 1KB and you get 4KB more without having to wait a full round trip.
But the PCjr said no. After a week of cleaning up the code and gathering stats I understand the problem better; it's just processing packets as fast as it can. The best speed-up on that specific test is 30%, which isn't bad, but not 5x.
@distrowatch I still maintain an FTP client and server, for DOS! It runs on a version as early as 2.1 on a minimal spec PC.
Turns out Netscape 2.02 is too easy, so in this picture is IBM WebExplorer v1.1h running on OS/2 Warp Connect. Using the magic "work area" feature of folders (mark a folder as a work area to have the OS manage objects within it as a kind of unit), I can open several windows at once. True multi-process browsing 😉

Anyway, I've reduced my ambitions ever so slightly, and am now in the process of installing NetBSD (-CURRENT) on what is essentially a 386SX-class machine: 16-bit bus, 24-bit addressing, 16MB RAM, and nearly as unpleasantly slow as the 286 I had planned to use. It is however equipped with an IBM-branded 486SLC, which is from the Blue Lightning series. This one definitely has a full 486 instruction set. More hardware details will follow when I've completed the build (and installation).
Meanwhile, the obligatory screenshot from the installer. Note the ETA for simply unpacking base.tgz ..

(In other news, the #snac instance on this poor Pentium Pro server is sweating hard whenever I post something. So let me know at @ltning@anduin.net if you have problems receiving/reading my posts. I've made some tweaks but it will be unavoidably detained for a while following each post, my apologies for that..)
The latest mTCP for DOS is available!
This version includes some changes to improve TCP reliability on long running (but idle) connections, black & white Sixel graphics in Telnet, a Telnet emulation bug fix, and other small fixes sprinkled around.
The source code to NetDrive (network attached storage) is also published now - enjoy reading an unholy mix of x86 assembly code talking to Golang over UDP!
Spread the word! Friends don't let friends run old code ...

I'll post each picture as a reply to this post, as snac doesn't like multiple attachments..
Enjoy. And wish the poor box luck serving this.
So..TLS aside, what is the most lightweight reverse proxy I can use instead of nginx
in front of this thing? You know, in case I would like to move the instance from this beefy PPro to, say, a #486 or a #Nintendo Wii running #NetBSD? :)
secp*
curves are orders of magnitude slower than X25519
and prime256v1
. At least on a Pentium Pro/Pentium II-class CPU.See also my main fediverse presence: @ltning@anduin.net
About this instance, at the time of writing:
- OS: #NetBSD 10
- Reverse proxy: nginx
- CPU: Dual Pentium Pro Overdrive, 333MHz
- RAM: 512MB EDO
- NIC: 3Com 100Mbit PCI NIC
- Storage: SATA 1.0 (CF and SSD)
