(Elisp) Yet Another Function To Save All File Buffers

(Hardware) Best Inexpensive Monitor Ever

Last year I searched for a monitor with these attributes:

23-inch
Great color and bright from all angles easy for all-day viewing
Cables: HDMI, DVI, and VGA
Inexpensive because of the obvious and also the possibility of building a 2×2 monitor grid

The ASUS VS239H-P 23-Inch Full HD 1920×1080 IPS HDMI DVI VGA Back-lit LED Monitor is my winner: it meets all of the criteria.

It is easy to use and looks great. One year old it still is selling well. It is an easy purchase because 8,299 owners ranked it a 4.5/5 so I’m not alone here.

Now join the club.

Avoid Most Bash Errors Pretty Much By Quoting Everything, And More Best Practices

This page shows common errors that Bash programmers make. These examples are all flawed in some way.

You will save yourself from many of these pitfalls if you simply always use quotes and never use WordSplitting for any reason! Word splitting is a broken legacy misfeature inherited from the Bourne shell that’s stuck on by default if you don’t quote expansions. The vast majority of pitfalls are in some way related to unquoted expansions, and the ensuing word splitting and globbing that result.

All of us have fallen into one of these pits.

Why not use Python instead? 🙂

Oh yea, non-interactive shells 😠.

(Packet Modem) Dire Wolf Is A Software Tnc/Aprs

Dire Wolf is a software “soundcard” AX.25 packet modem/TNC and APRS encoder/decoder. It can be used stand-alone to observe APRS traffic, as a tracker, digipeater, APRStt gateway, or Internet Gateway (IGate).

(Go Lang) Hopwatch, A Debugging Tool For Go

Hopwatch is a simple tool in HTML5 that can help debug Go programs. It works by communicating to a WebSockets based client in Javascript. When your program calls the Break function, it sends debug information to the browser page and waits for user interaction. Using the functions Display, Printf or Dump (go-spew), you can log information on the browser page. On the hopwatch page, the developer can view debug information and choose to resume the execution of the program.
