  • Redis introduce its new "available-source" license

    27 February 2019

    Redis Labs is dropping its Commons Clause license in favor of its new "available-source" license: Redis Source Available License (RSAL). This is not an open-source license. Redis Labs had used Commons Clause on top of the open-source Apache License to protect its rights to modules added to its 3-Clause-BSD-licensed Redis, the popular open-source in-memory data structure store. But, as Manish Gupta, Redis Labs' CMO, explained, "It didn't work. Confusion reigned over whether or not the modules were open source. They're not open-source." So, although it hadn't wanted to create a new license, that's what Redis Labs ended up doing. RSAL covers some Redis Modules, which run on top of open-source Redis. The current modules covered by RSAL are: RedisSearch, RedisGraph, RedisJSON, RedisML, and RedisBloom. Redis remains under the BSD license. The RSAL grants, Gupta said, equivalent rights to permissive open-source licenses for the vast majority of users. With the RSAL, developers can: Use the software; modify the source code; integrate it with an application; and use, distribute, support, or sell their application. But -- and this is big -- the RSAL forbids you from using any application built with these modules in a database, a caching engine, a stream processing engine, a search engine, an indexing engine, or a machine learning/artificial intelligence serving engine. In short, all the ways that Redis Labs makes money from Redis. Gupta wants to make it perfectly clear: "We're not calling it open source. It's not." At the same time, Redis Labs wants everyone to understand the new RSAL will have: Zero effect on the Redis core license, which is and will always be licensed under the 3-Clause-BSD. Unlike many other open source database companies, we have built a dedicated team (led by Salvatore Sanfilippo, the creator of Redis), who manages the Redis core in a completely independent manner. Additionally, we have chosen not to limit the functionality of open source Redis by moving core components to closed source. Consequently, open source Redis includes all the ingredients needed to run a distributed database system -- replication, auto-failover, data-persistence and clustering. Besides, Redis argues the RSAL doesn't target developers. Instead, as Redis Labs CEO, Ofer Bengal, recently put it, "Cloud companies [which] use their monopoly power to adopt any successful open-source project without contributing anything to it." Redis added in their announcement, "other respected open source companies, like MongoDB and Confluent, created their own proposals for modern variants to open-source licensing. Each company took a different approach, but all shared the same goal — stopping cloud providers from taking successful open source projects that were developed by others, packaging them into proprietary services, and using their monopoly power to generate significant revenue streams." Others don't buy this argument. Matt Asay, head of Adobe developer ecosystem, said: It has become fashionable to call out the cloud vendors, and particularly AWS, as parasitic destroyers of open source value. What real-world contributor data actually tells us, however, is that this view of the clouds is completely wrong, at least at the macro level. Google and Microsoft are orders of magnitude bigger contributors to open source communities than any other company. Even AWS, which has perhaps correctly been criticized as not 'doing more', is one of the world's top-10 largest contributors, and has scaled up its contributions considerably in the last year. It would seem that more cloud tends to equate with more open source. Perhaps, then, the clouds are not the enemies of open source, but the best allies. Gordon Haff, a Red Hat technology evangelist, pointed out recently that Redis' argument isn't new. In 2008, not long after Amazon Web Services (AWS) was founded, he saw the fear "companies will wholesale strip-mine Open Source projects." Despite Redis' arguments to the contrary, Haff doesn't believe that's the case. Instead, companies, including cloud businesses, are embracing open source not so much because of it lets you "view source code," but because of "its collaborative development model." Haff went on: "A lot of the heat around licenses like the Commons Clause comes about because the companies involved seem to be, on the one hand, trying to gain the perceived value of a proprietary license while also getting credit for still being open source. 'Open core' arguably plays the same parlor trick." Now that Redis has made it black and white that its new RSAL is not open source, while the Reddis code itself remains open source, perhaps the arguments will die down. In effect, what Redis is doing is putting its own license around the old open core business model. Source: ZDnet What the effect of that on future of the Open Source Software?!

  • ELISA: an open source project to enable Linux in Safety-Critical systems

    26 February 2019

    The Linux Foundation launched the Enabling Linux in Safety Applications (ELISA) open source project to create a shared set of tools and processes to help companies build and certify Linux-based safety-critical applications and systems whose failure could result in loss of human life, significant property damage or environmental damage. ELISA will make it easier for companies to build safety-critical systems such as robotic devices, medical devices, smart factories, transportation systems and autonomous driving using Linux. Additional project goals include: Develop reference documentation and use cases. Educate the open source community on safety engineering best practices and educate the safety community on open source concepts. Enable continuous feedback with the open source community to improve processes, and to automate quality assessment and assurance. Support members with incident and hazard monitoring of critical components relevant to their systems and establish best practices for member response teams. Founding members of ELISA include big companies like Arm, BMW Car IT GmbH, KUKA, Linutronix, and Toyota. ELISA project can be found on: and on GitHub:

  • Chromium and Chrome! ... What the difference?

    19 February 2019

    Google Chrome is a web browser developed and maintained by tech giant Google. Chrome uses the open source web browser Chromium’s source code and adds a bunch of features developed by Google and some non free components. Otherwise, Chromium is totally an open-source web browser developed and maintained by The Chromium Project and many contributors from the community of open source developers. Users can differentiate Chrome and Chromium browser by looking at their logo. Google Chrome is colorful, and Chromium is blue. However, that’s not the only difference between Chrome and Chromium. Other differences between Chrome and Chromium: 1- Automatic Updates Chrome uses Google Update on Windows (GoogleSoftwareUpdateAgent and GoogleSoftwareUpdateDaemon on Mac) to automatically update to the latest version. It is not available for Chromium. On some Linux distributions, updates are made available via package repositories. Google Update is also used for other applications like Google Earth. Don’t forget to read the difference between Google Earth and Google Maps. 2- Usage tracking and crash reporting Unlike Chromium, Google has added the crash reporting and send usage statistics options. Chrome sends data to Google servers. It includes general data like information about your device and OS, Chrome settings, visited websites having malware, search queries, etc. This allows Google to throw suggestions, results, and ads that are relevant to you. Crash reporting and usage tracking can be disabled from Chrome’s settings. 3- Chrome Web Store On Google Chrome, the functionality to add extensions outside the Chrome Web Store is disabled on all Windows and Mac Channels. However, the extensions can be added via developer mode. 4- Media Codec support Chromium’s HTML5 audio/video codec support is limited to what is available as non-proprietary codecs like Theora, Vorbis, WebM, VP9, etc. In the case of Chrome, it adds support for some non-free stuff like AAC, MP3, and H.264 (now free). 5- Non-optional tracking Google Chrome installer includes a randomly generated token. The token is sent to Google after the installation completes in order to measure the success rate. Google also uses the RLZ identifier to track a user on Google Search and while using the address bar. The RLZ identifier stores information – in the form of encoded strings – like the source of chrome download and installation week. It doesn’t include any personal information, and it’s used to measure the effectiveness of a promotional campaign. Chrome downloaded from Google’s website doesn’t have the RLZ identifier. The source code to decode the strings is made open by Google. 6- Sandbox Both Chrome and Chromium browser have Sandbox support. It is always enabled in the case of Google Chrome. For Chromium, some Linux distributions may disable the Sandbox feature.

  • NVIDIA open-sources hyper-realistic fake faces generator
