because this is a gist from 2011 that people stumble into and maybe you should AES instead of 3DES in the year of our lord 2019.

Latency Comparison Numbers (~2012)
----------------------------------
L1 cache reference                           0.5 ns
Branch mispredict                            5   ns
L2 cache reference                           7   ns                      14x L1 cache
Mutex lock/unlock                           25   ns
Main memory reference                      100   ns                      20x L2 cache, 200x L1 cache
Compress 1K bytes with Zippy             3,000   ns        3 us
Send 1K bytes over 1 Gbps network       10,000   ns       10 us

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

security and hardening options for systemd service units

A common and reliable pattern in service unit files is thus:

NoNewPrivileges=yes

Generate Symantec VIP Access Token as OTP

Recently I came across a web service that required two-factor authentication using the Symantec VIP Access App. I already manage all of my OTP tokens in a different app (If you are on iOS I highly recommend using OTP Auth by Roland Moers.) and did not want to have to use yet another app to generate the TOTP.

There is a way to generate a Symantec VIP Access compatible token very easily if you have access to an environment which can run Python PIP. I happen to have Ubuntu Windows Subsystem Linux running on my machine. (If you are running Windows 10 and don't have this you should really check it out.) Let's get started...

Here we install python3-pip and qrencode so we can generate our secret, I

blueprint:
  name: Frigate Notification
  description: |
    ## Frigate Mobile App Notification

    This blueprint will send a notification to your device when a Frigate event for the selected camera is fired. The notification will initially include the thumbnail of the detection, but will update to include actionable notifications allowing you to view the saved clip/snapshot when available, or silence the notification for a configurable amount of time.

    With this blueprint, you may send the notification to multiple devices by leaving "Device" blank and instead use a [notification group][1].
