- Drew DeVault
#LangaugeDesign
 
tl;dr: Drew counts the number of syscalls a language performs when printing "Hello World." This should take 2 syscalls but, for most languages, there's a lot more happening under the hood. 
- Caleb Doxsey
#LangaugeDesign
 
tl;dr: A response to the post above, Caleb argues that decreasing syscalls in a "Hello World" program results in "imperceptible performance improvement" while extra syscalls can provide value. Pursuing "software minimalism" doesn't always lead to improvements.

- Gaëtan Leurent & Thomas Peyrin
#SHA-1 #Security
 
tl;dr: Despite a decline in usage and already publicized vulnerability, researches have uncovered a more serious issue. A chosen prefix collision means you can create two different docs and add on some extra blocks so they collide.

#Innovation
 
tl;dr: Highly technical white paper. Fungi are "an ideal object for developing future living computing devices."
- Mallory Mooney
#DataDog #Infrastructure
 
tl;dr: Tagging is important for monitoring application data in modern environments. They "unify your metric, log, and trace data so that you can search for hosts and their services and easily move from one data point to another." 
- The CPython Core Developer Community
#Python
 
tl;dr: "The CPython core developer community is retiring the Python 2 series after nearly 20 years of development. The last major version 2.7 will be released in April 2020, and then all development will cease for Python 2."
