Automating SSH with Putty (Windows)

Putty is a tool which can be used for various purposes, including communicating with a Linux computer using SSH (Secure SHell) from a Windows computer. Given the username, hostname, and password of a Linux machine which is to be SSHed into, Putty can be automated from the command line as follows (assuming Putty is on the Windows path):

putty -ssh username@hostname -pw password

If the same user on the same Linux machine is to be accessed repeatedly, this command can be automated in Windows by creating a shortcut as follows:

  • Right click on the desktop/explorer

A script to build Haserl 0.9.29 with LuaJIT 2.0

This script modifies the Haserl 0.9.29 distribution so it works with LuaJIT 2.0 as well as Lua 5.1. The script takes a single argument that is the path to a LuaJIT / Lua distribution directory in which library and executable files have been built. A typical usage is

    ./build-haserl-luajit.sh /usr/local/src/LuaJIT-2.0.0/

The script patches configure.ac, builds Haserl, and executes a CGI script to verify that LuaJIT / Lua is working within Haserl.

The LuaJIT distribution builds both .so and .a libraries; this script always uses the .a library so the Haserl executable contains an embedded copy of LuaJIT. If you prefer to link dynamically to LuaJIT, modify the script to change

C99 List of Undefined Behavior (193 Cases)

C99 List of Undefined Behavior

From N1256: (See http://port70.net/~nsz/c/c99/n1256.html#J.2)

  • A "shall" or "shall not" requirement that appears outside of a constraint is violated (clause 4).
  • A nonempty source file does not end in a new-line character which is not immediately preceded by a backslash character or ends in a partial preprocessing token or comment (5.1.1.2).
  • Token concatenation produces a character sequence matching the syntax of a universal character name (5.1.1.2).
  • A program in a hosted environment does not define a function named main using one of the specified forms (5.1.2.2.1).
  • A character not in the basic source character set is encountered in a source file, except in an identifier, a character constant, a string literal, a header name, a comment, or a preprocessing token that is never converted to a token (5.2.1).
  • An identifier, comment, string literal, character constant, or header name contains an invalid multibyte character or does not

ARM’s Scalable Vector Extensions: A Critical Look at SVE2 For Integer Workloads

ARM’s Scalable Vector Extensions: A Critical Look at SVE2 For Integer Workloads

Scalable Vector Extensions (SVE) is ARM’s latest SIMD extension to their instruction set, which was announced back in 2016. A follow-up SVE2 extension was announced in 2019, designed to incorporate all functionality from ARM’s current primary SIMD extension, NEON (aka ASIMD).

Despite being announced 5 years ago, there is currently no generally available CPU which supports any form of SVE (which excludes the [Fugaku supercomputer](https://www.fujitsu.com/global/about/innovation/

The right way to override any highlighting if you don't want to edit the colorscheme file directly

The right way to override any highlighting if you don't want to edit the colorscheme file directly

Generalities first

Suppose you have weird taste and you absolutely want:

  • your visual selection to always have a green background and black foreground,
  • your active statusline to always have a white background and red foreground,
  • your very own deep blue background.
