[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).

Today's links 08/06/2015: #SSD no panacea for VMs, Hardware X86 #security breach, #Bigdata stream engine

  • SSD no panacea with VM : because of is operational model SSD tend to have poor performance in virtual environment when shared across multiple VM. The authors suggest to isolate and dedicate SSD for each VM in order to benefit from the speed benefit of SSD. Micro storage solution anyone ?
  • X86 design flaw : Apparently there is a way to escalate from ring 0 to the high privileged state. This can be really interesting if this would enable VM or container to escape and gain access to the bare-metal system. : :
  • Heron : the descendant of Storm by Twitter. The architecture seems nice and try to address some of Storm shortcoming.
