- View: Also called a "template", a file that contains markup (like HTML) and optionally additional instructions on how to generate snippets of HTML, such as text interpolation, loops, conditionals, includes, and so on.
- View engine: Also called a "template library" or "templater", ie. a library that implements view functionality, and potentially also a custom language for specifying it (like Pug does).
- HTML templater: A template library that's designed specifically for generating HTML. It understands document structure and thus can provide useful advanced tools like mixins, as well as more secure output escaping (since it can determine the right escaping approach from the context in which a value is used), but it also means that the templater is not useful for anything other than HTML.
- String-based templater: A template library that implements templating logic, but that has no understanding of the content it is generating - it simply concatenates together strings, potenti

Why do compilers even bother with exploiting undefinedness signed overflow? And what are those | |
mysterious cases where it helps? | |
A lot of people (myself included) are against transforms that aggressively exploit undefined behavior, but | |
I think it's useful to know what compiler writers are accomplishing by this. | |
TL;DR: C doesn't work very well if int!=register width, but (for backwards compat) int is 32-bit on all | |
major 64-bit targets, and this causes quite hairy problems for code generation and optimization in some | |
fairly common cases. The signed overflow UB exploitation is an attempt to work around this. |

This python script will find flatpak deduplication size stats. | |
Made with :heart: by powpingdone#3611, or just powpingdone on github. | |
Explaination for output: | |
'no dedupe': The size that the ostree repository would take up if files were not deduplicated. | |
'dedupe': The actual size of the ostree repository. | |
'singlet': The size of all files that are referenced once. | |
'orphan': The size of all files not referenced (ie, only one hard link). |
I have a pet project I work on, every now and then. CNoEvil.
The concept is simple enough.
What if, for a moment, we forgot all the rules we know. That we ignore every good idea, and accept all the terrible ones. That nothing is off limits. Can we turn C into a new language? Can we do what Lisp and Forth let the over-eager programmer do, but in C?
why doesn't radfft support AVX on PC?
So there's two separate issues here: using instructions added in AVX and using 256-bit wide vectors. The former turns out to be much easier than the latter for our use case.
Problem number 1 was that you positively need to put AVX code in a separate file with different compiler settings (/arch:AVX for VC++, -mavx for GCC/Clang) that make all SSE code emitted also use VEX encoding, and at the time radfft was written there was no way in CDep to set compiler flags for just one file, just for the overall build.
[There's the GCC "target" annotations on individual funcs, which in principle fix this, but I ran into nasty problems with this for several compiler versions, and VC++ has no equivalent, so we're not currently using that and just sticking with different compilation units.]
The other issue is to do with CPU power management.

Since modern.ie released vagrant boxes, it' no longer necessary to manually import the ova file to virtualbox, as mentioned here.
However, the guys at modern.ie didn't configured the box to work with WinRM. This how-to addresses that, presenting steps to proper repackage these boxes, adding WinRM support. Additionally configures chocolatey package manager and puppet provisioner.
