When I started working on NSS 7 months ago one of the tasks I was asked to do was to work through the related Coverity issues. This post summarises some learnings from this as we’ve since come a long way since over the last months.
Static analysis plays a crucial part in locating vulnerabilities and bugs during development. For NSS we currently use multiple static analysis tools. While scan-build as well as infer are great applications to find bugs, they require a lot of manual management.
~This extension doesn’t work from Firefox 57 on. I might update it when I find time.~
Ever wanted to view HTML pages directly from GitHub? Me too. Unfortunately the Raw button doesn’t render the HTML but only displays the source code. There are a bunch of Chrome extensions that add a button to open file from Github at rawgit directly, but none for Firefox. So I wrote one. It’s still an early version and more of a hack than a real extension, but it works (mostly).
Today I had to submit a paper through the Editorial Manager (used by Springer) for the first time. Needless to say that it’s not as easy as it sounds. Therefore here some helpful links for everyone having to do the same. I ended up putting the references in the .tex file as nothing else worked for me.
OpenPVN is an easy to set-up and use VPN solution that offer TUN/TAP support. In this tutorial I describe how to set-up an OpenVPN connection between a Ubuntu server and an Arch client.
Preparations (Server) First we have to install OpenVPN on the server.
# apt-get install openvpn To see whether TUN/TAP is enabled in the kernel we can check the kernel log grep tun /var/log/kern.log and load it if it doesn’t show up modprobe tun.
This post is work in progress but I never got around to finishing it. Sorry
After a first failed attempt to install Snorby on an Arch Linux server (Snorby requires Ruby 1.9.x, Arch uses 2.x and I’m not willing to use the AUR version for this) I’m doing this on a Ubuntu 14.04 Server.
Snort Before installing Snorby we have to install snort itself. This can be done with sudo apt-get install snort.
Over the last year I was battling a strange error of reverse synctex search with evince and several latex editors. Everything works perfect with synctex unless I want to do a reverse search (click in the pdf docutment and get the according tex position) on the first page. Instead of getting the correct position my latex editor always opens the file pgflibraryfadings.code.tex. While I finally found the cause of the problem, I have no idea how to solve it.
Another day in latex wonderland … Today I was writing an equation in an aligned environment using sum and those fancy things. Unfortunately aligned is a display math environment such that the limits of sum are displayed above and below, which was really not suitable in my case. So how do I display inline-math style in a display math environment?
Let’s say we have an equation environment with an equation
