Zoom Sucks

Zoom Sucks

  • Zoom abuses the installer flow on MacOS to bypass permissions dialogs (source)
  • Zoom sends identifying device info to Facebook, even when users don't have a Facebook account (source) (fixed)
  • A bug in Zoom sent identifying information (including email addresses and profile pictures) of thousands of users to strangers (source)
  • Zoom claims that meetings are end-to-end encrypted in their white paper and marketing materials, but meetings are only encrypted in transit, and are available in plaintext to Zoom servers and employees. (source)
  • zoomAutenticationTool can be used to escalat

Liberal, Accurate Regex Pattern for Matching Web URLs
The regex patterns in this gist are intended only to match web URLs -- http,
https, and naked domains like "example.com". For a pattern that attempts to
match all URLs, regardless of protocol, see: https://gist.github.com/gruber/249502

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs
