In the last years, I spent some of my scarce free time writing up what I had learnt starting and running two companies, zynamics and optimyze

The article is still work-in-progress, but I thought it's best to publish it now and iterate in public:

I frequently wonder why I insisted on Google paying me in cash instead of stock in 2011, and then I remembered: The total real return of the SP500 between March 2000 (when I turned 18) and February 2011 (when we sold zynamics) was negative, and it would take until June 2013 before it was positive.

Också nice att bli inbjuden till hens (fd Zynamics, Project Zero, den som vet vet) strandhus i södra Frankrike. Fint med vänner överlag, även såna man inte träffar så ofta.

Google bought Zynamics, a company founded by @HalvarFlake. Awesome! http://blog.zynamics.com/2011/03/01/zynamics-acquired-by-google/

Avaya did it with Sipera, Google with Zynamics, and Twitter with Whisper Systems.

Was painfully reminded today that our old #zynamics adage "Everything is always broken" is very true.

Happy to be of service. I have no plans to stop, but I am a bit behind with a new release.
#BinDiff and my time at zynamics have been among the best things that happened to me. https://x.com/halvarflake/status/1514511185726558212

Blast from the past: 10 years ago at #zynamics, we use Parabuild to build and deliver #BinDiff and #BinNavi. TIL, it has been open sourced in the meantime: https://github.com/parabuild-ci/parabuild-ci
I wish I could say I fondly remember it, but we switched to @jenkinsci eventually. ¯\_(ツ)_/¯

Resurrected a static copy of our old zynamics blog from the dead: https://blog.zynamics.com/. There's not exaclty rocket science in there, but we'll keep it around for archival purposes indefinitely.

Just pushed zynamics BinExport to https://github.com/google/binexport. Use with the BinNavi "binexport9" branch. Linux, OS X and Windows support.

Fun fact: The accidental graylisting of http://zynamics-orders.appspot.com is oddly satisfying. #IPromiseIllFixItSoonish

#zynamics #BinDiff 4.0.1 with a few fixes is up :) -- if you're a 4.0 customer, just use the download links you received in your e-mail.

Working at zynamics definitely has swing...

In the last years I wrote up what I learnt from doing two companies, zynamics and optimyze.

It is still work-in-progress, but it is ~27 pages, and I think helpful for everybody that is considering…
