[Archive] SimenHolmestad/Privacynator: A utility for removing Personally Identifiable Information (PII) from videos.
Privacynator is an utility for removing Personally Identifiable Information (PII) from videos. It is primarily meant for videos captured from cars.Privacynator uses the Detectron2 model from facebook research: https://github.com/facebookresearch/detectron2.
It is written in Python 3.
It is unlike this: Need to check if “PrivacyNator” is already out: a local TensorFlowJS app that blurs your screen when you are not behind it

An interesting thought: [Archive] Kristian Köhntopp on Twitter: “Basically, show me a Python regex with \d and without ASCII flag, and I can show you a bug, often exploitable.… “
Basically, input parsing is still very much underrated by most systems and a constant source of peculiarities and therefore bugs, or phrased differently: [Archive] Kristian Köhntopp on Twitter: “In many cases an uncaught exception, and hence a component crash.… “
Kris also states [Archive] Kristian Köhntopp on Twitter: “Again, Python is not alone in this. Perl, when “use utf8;” is active (which it should) also does this, so every single fucking Regex needs a ‘/a‘ at the end. Nobody ever asked \d to match tengwar or klingon numeric symbols.… “.
The point is in the last few words as Arabic numerals are so white spread over the world that the ten digits 0, 1, 2, 3, 4, 5, 6, 7, 8 , 9 they represent should be the de facto \d pattern, but aren’t in Python as per [Wayback/Archive] re — Regular expression operations — Python 3.10.0 documentation: /d (emphasis mine):

For my link archive: [Wayback/Archive] google chrome devtools – Use JavaScript to set value of textbox when .value and events don’t seem to work – Stack Overflow
Sometimes fields are blocked from pasting values.
Normally a trick like this works in the chrome development panel console:
document.getElementById('nonPasteElementID').value = 'myValueFromTheClipboard'
With some web development environments this does not work.
For react, after finding the react render name for the input (in the case of the answer, it was “reactNameForInputElement“) this is a solution:
To make it work you will need this:
const input = document.getElementById('nonPasteElementID'); const event = new Event('reactNameForInputElement', { bubbles: true }); input.value = '1'; input.dispatchEvent(event);

I have been into more and more Mojibake example pages like [Wayback] Mojibake: Question Marks, Strange Characters and Other Issues | GPI
Have you ever found strange characters like these ��� when viewing content in applications or websites in other languages?
They made me realise that all these (including the Mojibake examples on my blog) are just artifacts, but the real list of examples is the set of ftfy test cases at [Wayback/Archive.is] python-ftfy/test_cases.json at master · LuminosoInsight/python-ftfy
I got reminded when Waternet moved from paper mail using “Pyreneeën” to email using “Pyreneeën“. Not as bad as Waterschap AGV did earlier: they took it one level further and made “Pyreneeën” out of it, see Last year, a classic Mojibake was introduced when Waterschap Amstel, Gooi en Vecht redesigned their IT systems.
This seems like a trend where newer systems perform worse than older systems. I wonder why that is.
BTW: the trick on the [Wayback/Archive] Python.org shell to run ftfy (which is not installed by default) is first dropping to the shell (see my post How do I drop a bash shell from within Python? – Stack Overflow), then starting python again:

I knew there was JSFiddle for live playing around with JavaScript and more in your browser, so I wondered if there was a similar site for databases and SQL queries.
There are, so here are a few database fiddle sites: SQL playgrounds where you can live play with SQL queries (sometimes even without an underlying example database).
All via [Wayback/Archive.is] database fiddle – Google Search:

With APIs, you always hope that Get and Set methods mirror each other. More often than not, they don’t.
Take for instance these two:
Get-NetFirewallRule (NetSecurity) | Microsoft DocsSet-NetFirewallRule (NetSecurity) | Microsoft DocsThey are far from symmetric: [Wayback/Archive] Get-NetFirewallRule shows far less than [Wayback/Archive] Set-NetFirewallRule allows you to set (first and foremost the various port related properties). It can be worked around though.
There are a few posts discussing this, of which I think these two are the most important:
Both above posts via [Wayback/Archive] “Get-NetFirewallRule” “LocalPort” – Google Search.
This is what I was after:
PowerShell "Get-NetFirewallRule -Name 'RemoteDesktop-UserMode-In-TCP' | Select-Object Name,DisplayName,Enabled,Direction,@{Name='Protocol';Expression={($PSItem | Get-NetFirewallPortFilter).Protocol}},Action,@{Name='LocalPort';Expression={($PSItem | Get-NetFirewallPortFilter).LocalPort}}"
Or actually:

An interesting thread by Kristian Köhntopp last year:
[Archive.is] Kristian Köhntopp on Twitter: “Python: >>> print(1+2+” = “+2+1) Traceback (most recent call last): File “”, line 1, in TypeError: unsupported operand type(s) for +: ‘int’ and ‘str’ Java: System.out.println(1+2+” = “+1+2); 3=12”
The examples from him and others in the thread:
Python: >>> print(1+2+" = "+2+1) Traceback (most recent call last): File "", line 1, in TypeError: unsupported operand type(s) for +: 'int' and 'str' Java: System.out.println(1+2+" = "+1+2); 3=12 php8.1 -r 'print 1+2+" = "+2+1;' PHP Fatal error: Uncaught TypeError: Unsupported operand types: int + string in Command line code:1 Stack trace: #0 {main} thrown in Command line code on line 1 php7.3 -r 'print 1+2+" = "+2+1;' PHP Warning: A non-numeric value encountered in Command line code on line 1 Node? Chrome & FF dev console: window.alert(1+2+" = "+1+2) 3 = 12 Sind ja immerhin verschiedene Sprachen. SELECT Wert1 FROM table1 WHERE Wert1 < AVG(Wert1); DB2 vs. Oracle vs. MSSQL vs. ....
The joke is that Python actually does better than Java.
But in practice, this is a problem on many platforms, so it deserves constant attention, that’s why Kristian pointed to [Archive] Anna “Legacy Archaeologist” Filina on Twitter: “My annotated slides “Fantastic Bugs and How to Avoid Them” from @LonghornPHP: #LonghornPHP”

I’ve expanded the examples from the thread below. The results are interesting and consistent over versions of the various languages.
