Writing a dynamic library in Crystal, and calling it from C

• Download all files.
• Build the Crystal part:

crystal build --release --cross-compile --prelude ./no_main library.cr
              ^ You can leave this out
                        ^ We want to link ourselves!
 ^ Use our custom prelude!

Description

This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.

The script is here:

#!/bin/bash
convert "$1" -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 "$2"

.gemsig Proposal

RubyGems.org has little in the way of defenses against tampering. Right now, new gems could be uploaded to S3 and distributed to users worldwide without detection, and the only thing preventing this is the security of the AWS credentials presently stored on world-facing web servers. S3 Versioning is a step that could be taken immediately to reduce the severity of compromise, but a larger solution is required.

This document proposes a .gemsig file as a means of verifying that a gem has not been modified during distribution. This file would be distributed alongside the .gem files, allowing clients to verify authenticity.
