Is it possible to simulate transistors using open-source tools only?

How fast are the available solvers?

How hard is it to interface with existing PDKs?

The following talks provide very promising answers:

* ngspice - an open source mixed signal circuit simulator, by Holger Vogt

* Gnu Circuit Analysis Package (GnuCap), by Al Davis

* Converting 45nm transistor netlists to open standards, by Thomas Benz

Which foundries are the most friendly to open-source? Is there an open-source #PDK?

Kholdoun Torki of Circuits-Multi-Projects ( provided a great overview:

"Towards Foundry PDKs on Free CAD Tools"

The web browser Brave is marketed as a privacy-friendly ad-free alternative, but that's pretty disingenuous.

Brave exists not to protect privacy, but to make money from selling ads.

Brave is a commercial company funded by venture capital. Its business model is selling advertising and cryptocurrency investment.

One of Brave's owners is Peter Thiel's Founders Fund. Thiel is also the head of Palantir ( and on the board of Facebook.

I do not recommend using Brave.

All the recordings of the Free Silicon Conference are now online:

Day 1 focuses on high-level design. Some of the concepts presented in the first talks can be partially applied to FPGAs as well

Day 2 discusses aspects closer to silicon, such as PDKs, memory generators and layouting

Day 3 presents hands-on tutorials

🙈 Youtube-Filter stufte Video von Notre-Dame-Brand als Fake-News ein

Ein Algorithmus hat bei einigen Live-Videos über den Brand der Kirche Notre-Dame eine Warnung eingeblendet und auf den 11. September verwiesen.

Eigentlich bin ich kein Pessimist, aber ich denke, dass morgen das Internet zu Grabe getragen wird. Die EU-Staaten werden morgen der EU-Copyrightreform zustimmen. In ein paar Jahren werden sich dann alle wundern, weshalb Google und Co. noch größer und mächtiger geworden sind und es wird nach einer Reform von der Reform gerufen.

Ich sage: "...denn sie wissen nicht, was sie tun". :-(

And when I tried to post the above update to Twitter, this is what I get. Account locked!

They censor posts about #FreeAssangeRally #Assange and #wikileaks in an effort to prevent it from trending. Same thing happened last week too, and my account got shadow-banned.

Springer klagt mal wieder gegen Adblock Plus. Diesmal versuchen sie es mit dem Urheberrecht. Zitat: "Werbeblocker verändern die Programmiercodes von Webseiten und greifen damit direkt in das rechtlich geschützte Angebot von Verlagen ein", sagte Claas-Hendrik Soehring, Leiter Medienrecht bei Axel Springer.

Kann dem Mann mal jemand erklären wie Werbeblocker funktionieren? Das ist ja hochpeinlich.

Übrigens: Installiert euch einen Adblocker! Aber bitte uBlock Origin:

Asking for email passwords to "verify" new accounts is obviously a bad idea. So why did Facebook do it?

Und nochwas zu DNS over HTTPS (DoH) in Firefox:
- Ich will den DNS-Server selbst bestimmen können - über die GUI und nicht die about:config.
- Cloudflare als Standard geht gar nicht
- Eigentlich will ich keine Software auf dem System haben, welche meine selbst definierten System-DNS-Server umgeht

Daher: Ich tendiere klar zu DNS over TLS (DoT).

Things that can still stop #Article13:

-Council of Ministers can still reject it

-Individual countries still have to create their own laws to enforce it (this is not like GDPR, which came into force directly). This could cause a lot of friction against the law.

-Article 13's requirements are technically impossible: it requires filters to stop all piracy while allowing all fair use. This makes the law vulnerable to being rewritten/rejected at some point in the future.
