[Links of the Day] 08/08/2017 : Python image drawing & animations, Breaking x86 ISA, Correlation between NYT and Stock markets

  • pywonderland : A collection of python scripts for drawing beautiful figures or animating interesting algorithms in mathematics.
  • Breaking the x86 ISA : Back hat conf presentation on the sand sifter tool for detecting hardware bug or undocumented instruction in modern processors. Sadly, it's known that Intel's microcode binaries are encrypted, and are secured with a RSA2048-SHA256 signature. Which makes any discovery a little bit useless. Unless it's a bug and then it opens up a whole new world of possibility. [Slides] [Github]
  • Correlations and Flow of Information between The New York Times and Stock Markets : Well as everybody knows, there is a correlation between information and the market state. Nothing new, but it confirms to some extent that the new york time especially has a specific influence on wall street ( and vice versa).

[Links of the Day] 03/08/2017 : NVMe over TCP , Lineage mapping of cryptocurrency , Perceptions of probability

  • NVMe Over TCP : interesting kernel module by solarflare that allow people to use NVMe over TCP. It will be really interesting to see what type of performance you can start to get out of such setup. Even if performance is significantly decreased ( but higher than other storage solution) the economic gain vs costly NVMe solution would make this worth it. Also, It can start to accelerate the arrival of a new type of high-performance low-cost storage applications by lowering the barrier to entry.  
  • Map of Coins : Impressive lineage mapping of crypto currency. But what is more concerning is the amount of dead Bitcoin child cryptocurrency, a lot of pump and dump scheme going on
  • Perceptions : this really cool graphics show the how human perceive probability and how fuzzy it can be.  This can explain why a certain type of person might take more risk or less based on certain information due to a different interpretation of the content.

[Links of the Day] 01/08/2017 : Os Image generation, K/V optimized for SSD, Command line cloud deployment tool

  • mkosi : Tool for generating OS image. This is nice if you need to create an maintain low-level OS image with EFI support and GPT based table. It is invaluable if you do bare metal deployment / PXE  based deployment. [github]
  • WiscKey : Key / Value pair system optimised for SSD systems. Especially aiming at avoiding write amplification with traditional LSM based K/V system. 
  • Arc :  plaintext manifest for provisioning and deploying a cloud infrastructure. It's quite nice and elegant interface for such tedious task. If you have used chef, puppet, cloud formation or terraform you know how verbose this can get.
