Friday Hacks #134, April 7

Posted on by Jethro Kuan

Welcome back to our last episode of Friday Hacks for this semester! This week we’ll be having Peter over to talk about Nix and NixOS. Nix and its related technologies bring a radically different approach to server/container management and allows you to provision OS and software in repeatable and consistent ways. Also, if you’re curious about row hammering as a means of exploitation, mentioned last Friday Hacks by Halvar, Vishnu will be sharing about it in detail in the second talk.

Date/Time: Friday, April 7 at 6:30pm
Venue: SR5, Town Plaza, University Town, NUS
Free pizza is served before the talks.

(Programming your OS && ignoring state) == bliss

Talk Description:

NixOS fundamentally changes how we approach servers, instances and infrastructure and it all comes down to a quirky functional programming language named “nix”.

This talk covers some of the problems we can solve when we don’t have to care about mutating state and how adding a real programming language to our infrastructure enables us to do things we couldn’t do before.

Row Hammer: Flipping Bits in Memory Without Accessing Them

Talk Description:

“Row Hammer” is a problem with DRAM in which repeatedly accessing a row of memory can cause bit flips in adjacent rows. This talk will be describing how DRAM chips work, how the row hammer problem occured and finally how random bit flips in memory can be exploited into a privilege escalation attack.
