So how do we protect ourselves against unauthorized third parties building facial recognition models that recognize us wherever we may go? Regulations can and will help restrict the use of machine learning by public companies but will have negligible impact on private organizations, individuals, or even other nation states with similar goals.

The SAND Lab at University of Chicago has developed Fawkes1, an algorithm and software tool (running locally on your computer) that gives individuals the ability to limit how unknown third parties can track them by building facial recognition models out of their publicly available photos. At a high level, Fawkes "poisons" models that try to learn what you look like, by putting hidden changes into your photos, and using them as Trojan horses to deliver that poison to any facial recognition models of you. Fawkes takes your personal images and makes tiny, pixel-level changes that are invisible to the human eye, in a process we call image cloaking. You can then use these "cloaked" photos as you normally would, sharing them on social media, sending them to friends, printing them or displaying them on digital devices, the same way you would any other photo. The difference, however, is that if and when someone tries to use these photos to build a facial recognition model, "cloaked" images will teach the model an highly distorted version of what makes you look like you. The cloak effect is not easily detectable by humans or machines and will not cause errors in model training. However, when someone tries to identify you by presenting an unaltered, "uncloaked" image of you (e.g. a photo taken in public) to the model, the model will fail to recognize you.

Wonderful tool(s)! The Docker image is 1,6GB big, but it does combine quite a lot of things and makes it very convenient to use. In contrast to other such performance tools sponsored by a big company, Sitespeed.io complains about GA and GTM usage. ;-)

#^Sitespeed.io - Welcome to the wonderful world of Web Performance
Sitespeed.io is a set of Open Source tools that makes it easy to monitor and measure the performance of your web site.

Measuring performance shouldn’t be hard: you should be able to have full control of your metrics, own your own data and you should be able to do it without paying top dollars.

That’s why we created sitespeed.io.

The TSDB is something I want add to our monitoring server.

The MIT License is the most popular open-source software license. Here’s one read of it, line by line.

Read the License
If you’re involved in open-source software and haven’t taken the time to read the license from top to bottom—it’s only 171 words—you need to do so now. Especially if licenses aren’t your day-to-day. Make a mental note of anything that seems off or unclear, and keep trucking. I’ll repeat every word again, in chunks and in order, with context and commentary. But it’s important to have the whole in mind.

Q Light Controller

 Sat, 10 May 2014 23:45:04 +0200 
Got quite shocked when I saw that the amazing lighting control program QLC (Q Light Controller) by Heikki Junnila was not developed any further anymore. :'(:'(:'(

#^Q Light Controller
Q Light Controller is a cross-platform application for controlling DMX or analog lighting systems like moving heads, dimmers, scanners etc. The goal is to replace hard-to-learn and somewhat limited commercial lighting desks with FLOSS. Many people respect others opinions and therefore might like to see some ...

I loved this program and also had my first programming experiences with QT with this program. Have just done some small fixes, tiny new features and translation. At the end I tried to implement a bigger new feature some kind of a textbook that could be used to run theatre plays or other text centric shows. I had an editor and all functions to add and control scene changes and in the end I had a massive QTextDocument with a lot of blocks and metadata with all the scenes, but failed to store and restore it, so it never made it into QLC. :-( There is a QT feature request for some years already, but it is still not implemented.

Unfortunately I haven't had much time and occasions to play with my lights and QLC in the last two years, too. There was a fork and Massimo Callegari took over the development of QLC and it is called now QLC+ and got some very impressive and great new features! Really impressive the progress and nice to see that there is still an open source alternative to all the commercial lighting control softwares.

#^QLC+ by Massimo Callegari
QLC+ is a free and cross-platform software to control DMX or analog lighting systems like moving heads, dimmers, scanners etc. This project is a fork of the great QLC project written by Heikki Junnila that aims to continue the development of QLC and to introduce new features. The primary goal is to bring QLC+ at the level of other lighting control ...
