detect and visualise git commits' patch-based dependencies

a project by aspiers

It is well-known that two git commits within a single repo can be independent from each other, by changing separate files to each other, or changing separate parts of the same file(s). Conversely when a commit changes a line, it is "dependent" on not only the commit which last changed that line, but also any commits which were responsible for providing the surrounding lines of context, because without those previous versions of the line and its context, the commit's diff would not cleanly apply. As with most dependency relationships, these form a directed acyclic graph. Sometimes it is useful to understand the nature of parts of this graph; for example when porting a commit "A" between git branches via git cherry-pick, it can be useful to programmatically determine in advance the minimum number of other dependent commits which would also need to be cherry-picked to provide the context for commit "A" to cleanly apply.

Rusty Web

a record by oholecek

There is this rather new programming language from Mozilla called Rust. Its in development for over a two years and it is finally getting to some stable point and not changing every night or so. The language has many interesting features and concepts for safe concurrency and high performance worthy exploring. Thanks to my subtle desire to recover some long lost web programming skills I want to test how will Rust do as a, albeit very limited, web framework.

Learn Rust

a project by aplanas

Rust, the new language from Mozilla Foundation, is a modern systems programming language focusing on safety and speed. It accomplishes these goals by being memory safe without using garbage collection. Go, D and Nim have GC integrated into the language and the standard libraries. The GC in Rust is integrated as an external library.

Chromium/Chrome extension for SSL pinning

an idea by thardeck

Most browsers have more than 100 CA certificates (for example Firefox ~176) and everyone of them can sign certificates for any website. So if anyone of them is hacked, forced by law or just corrupt a man-in-the-middle attack is possible on any SSL connection.

Try to model check gfp_flags with cbmc

a project by vbabka

Paul McKenney's blog article inspired me to try apply his approach to kernel's memory allocation flags (gfp_flags) and how their combinations affect the decisions and actions taken during page allocation. Recent upstream development around these flags leads me to believe that the complexity is too high for me to reason about them and change the code without unintended changes in semantics. So it might be worth to let the computer do the hard work. If it works out, the approach should allow to verify that changing the code doesn't result in corner cases where some flag combinations don't work as intended. Then we can attempt to e.g. reduce the number of flags and perform other cleanups without fear of breaking everything.

Provide tools to analyze the life-time of maintenance and release requests in IBS/OBS

an invention by psimons

We need statistical analysis and key performance indicators to describe the lifetime of maintenance and release requests in IBS, for example: - How long does an update take starting from the time the first maintenance request is created and stopping at the time the update is released to customers?

Use linear programming for the partitioning proposal

an idea by ancorgs

The YaST team is rewriting yast2-storage. That includes new shiny code for the storage proposal during installation. It calculates what partitions and/or volumes need to be created to allocate the system and finds the best way to create those partitions in the existing free spaces. The second part becomes more complicated than it looks as soon as you start considering the restrictions imposed by each volumes and by the technology (primary vs logical partitions, for example). Right now, the problem is solved by brute force. All the possible distributions of partitions and LVM physical volumes are considered and the best one (according to several simple criteria) is chosen.

Reverse engineer memory layout

an invention by mkoutny

TL;DR Use convolution to find type candidates, then solve system of equations to refine the result. You are given a set of memory regions. And set of types (structures) that can possibly be present in the regions.
