The challenges with the open-source model

Developing a successful open-source project is not easy As we can see from its history, there has always been a tension in open source: e.g., philosophical licenses focused on preserving “freedom” vs. permissive licenses taking a pragmatic approach. But there are two larger tensions today: (1) how to balance openness with sustainability and (2) how to manage the transition to the cloud.

Remember Chinese Spy Chips? It’s complicated – and probably a hoax

Reality update: Hype um “chinesische Spionagechips” kommt vom Pentagon – fm4.ORF.at
Especially regarding:

Die Sensationsmeldung des Wirtschaftsportals Bloomberg über manipulierte Hardware für Cloud Computing stellt sich im FM4-Faktencheck als fast völlig faktenfrei heraus. Am Freitag kam ein langerwarteter Bericht des Pentagon heraus, der vor der Elektronikfertigung in China warnt. (…) Der Börsenkurs des Motherboard-Herstellers Supermicro wurde fast halbiert, etwa 500 Millionen Dollar an Börsenwert gingen verloren. (…) In Folge gingen auch völlig unbeteiligte Hardwarefertiger aus China in den Börsenkeller, Lenovo etwa notierte am Freitag bei minus 15 Prozent. Insgesamt gingen damit mehrere Milliarden Dollar an Börsenwert den großen Datenstrom hinunter, obwohl erst Supermicro, dann Amazon und Apple in scharfen Worten dementiert hatten. Diesen Dementis folgte noch ein weiteres und zwar von Bloomberg selbst, direkt am Ende des Artikels: „Auch Bloomberg LLP ist Kunde von Supermicro. Laut einem Sprecher des Unternehmens sind keine Indizien gefunden, dass die von Bloomberg benutzte Hardware solche Probleme aufweist, wie sie im Artikel beschrieben sind.”

Strange, um? 

Markus Feilner’s OpenVPN Trainings at Linuxhotel

Since 2010 Markus Feilner has been sharing his Open VPN know-how in the wonderful location of the Linuxhotel in Villa Vogelsang in Essen, Germany. The wonderful hotel and training center are situated in a green and fresh park on a cliff above the Ruhr river. Its exclusive amenities range from sauna and spa to excellent food and extraordinary ideas for the evenings. (Watch the video beneath this post!)

Usually, Markus’ Open VPN training lasts for three days and covers basics, administration and advanced features of Open VPN in hands-on sessions. Whereas the first day is full of basic concepts and theory, day 2 and 3 will give participants hours of guided work with setup and exploring the abundance of Open VPN servers and clients, including deep dives into individually agreed on features.

Contact us or the Linux Hotel directly for requests about the class specified here: https://www.linuxhotel.de/kurs/openvpn/. Giving trainings at Linxhotel has always been a great pleasure, also because there are a lot of interesting and highly skilled parallel classes going on at the venue, the participants and trainers of which you will meet at lunch, breakfast, dinner, in the park or at the evening events. Linuxhotel is my favorite venue for any kind of training.
