I love that the networking stack uses SLIP and slattach(1)! I was playing with a toy TCP/IP stack, and decided using SLIP over a pty on Linux was a great way to interface with the kernel. Unfortunately it looks like macOS previously s

Another option is to use the p5.js library. They also have a nice online editor, at https://editor.p5js.org/ , which makes it easy for students to get up and running quickly.

Very interesting telnet site, thank you for sharing! FYI, though, I think this may be looking at the wrong object ID. It selected "31", which appears to be the entry for one of the Lagrange points. Voyager 1 and 2 appear to have

I have a domain I've been using for some 20 years as my primary email address. There are some gmail users I can send mail to without any problems at all. For other gmail users, my messages appear to go into a black hole, not even sho

The post does a poor job explaining it, but the term "gaping security hole" comes from traditional netcat's source code. In order to enable the "-e" (exec) flag, it must be compiled with "-DGAPING_SECURITY_HOLE

The README that Hobbit (author of the original netcat) wrote is a really good read. I learned a lot when I first read it years and years ago. I especially remember it describing how it is possible to get "in front" of another dae

I've been using a perl-based calc for a number of years now. It started as a one liner eval-ing expressions on the command line. My favorite feature is that if symlinked as "hex", "oct", or "bin", it pr

It looks like the new XPS models have a single trackpad soft-button area (as all new laptops seem to). Have you been able to middle click to paste in X with this configuration? Thanks!

Don't die without a will. If you do and you appoint an executor, you are giving them a very dirty job This is one of the reasons I've been putting off completing a will :-( Is there a good option for going about this without nam

Regarding a living will, one I've seen that I really like is Five Wishes ( https://www.agingwithdignity.org/five-wishes.php ). I have one filled out that I've been procrastinating giving to friends and doctors, whi

You're right, "missing" was a poor choice of words. I meant, "vim keybindings for these commands isn't supported" . They are keybindings my fingers reach for everyday without thinking about it, similar to h

I get my hopes up when I see another vim emulation project, but after using it for just a few minutes, I already found a few missing vim features I use every day: * Toggling if search results should be highlighted ( :set hls , :set nohls )

A few years ago, I heard an NPR interview with a doctor who's friend was terminally ill. Rather than opt for treatment, the friend spent his remaining time living with his doctor friend. He died a few months later. The doctor said

I wish I had time to cite a reference, but my memory is that an ANY query is not guaranteed to return all RRs, anyway. Running a quick experiment against bind 9.8.4 (as packaged in Debian stable), I can confirm that: * When no entry alread

Under what conditions do you have a usefully functioning system when the clock is so off you need to do multi minute jumps? One example is embedded systems. Many don't have an RTC, or boot after the RTC has lost power. If a network

I wrote the original tcptraceroute in 2001. The article mentions many traceroute implementations change the source port to associate queries with responses. Another technique is to use the IP ID field, leaving the source port static. In

I once wrote an implementation of the classic Redcode "Imp" program in x86 assembly. It does not satisfy the requirements of this contest, but it does act as the Imp program, perpetually copying itself through RAM. :-) I just upl
