Chinese companies, and the government, see open models as the quickest way to narrow the gap with America. DeepSeek’s models have generated the most interest, but Qwen, developed by Alibaba, is also highly rated, and Baidu has said it will soon open up the model behind its Ernie chatbot. China’s enthusiasm for open technology is also extending to hardware. Unitree, a robotics startup based in Hangzhou, has made its training data, algorithms and hardware designs available for free, which may help it to shape global standards. Semiconductors offer another illustration. China is dependent on designs from Western chip firms. As part of its push for self-sufficiency, the government is urging firms to adopt RISC-V, an open chip architecture developed at the University of California, Berkeley. Many Chinese firms also hope that more transparent technology will help them win acceptance for their products abroad.

Most can’t keep their plan as long as they want, or visit any doctor or hospital. Some reforms, like Medicare For All, *would* let you. In other words, M4A actually offers more choice than the status quo. So if a politician tells you they oppose reforming the current healthcare system because they want to preserve "choice," either they don't know what they're talking about - or they're willfully ignoring the truth.

He found one — US8341419 — that mentioned jumping from ring 3 to ring 0 and protecting the machine from exploits of model-specific registers (MSRs), manufacturer-created commands that are often limited to certain chipsets. Domas followed the "trail of breadcrumbs," as he put it, from one patent to another and figured out that certain VIA chipsets were covered by the patents. Then he collected many old VIA C3 machines and spent weeks fuzzing code. He even built a testing rig consisting of seven Nehemiah-based thin clients hooked up to a power relay that would power-cycle the machines every couple of minutes, because his fuzzing attempts would usually crash the systems. After three weeks, he had 15 GB of log data — and the instructions to flip on the backdoor in the hidden RISC chip.

Companies in the embedded industry not playing by the same rules as every other company using our software violates users' rights, misleads users and developers, and harms our ability to continue our work. Though I've only gone into depth in this announcement on the latest trademark violation against us, our experience with two GPL violations over the previous year have caused an incredible amount of frustration. These concerns are echoed by the complaints of many others about the treatment of the GPL by the embedded Linux industry in particular over many years. With that in mind, today's announcement is concerned with the future availability of our stable series of patches. We decided that it is unfair to our sponsors that the above mentioned unlawful players can get away with their activity. Therefore, two weeks from now, we will cease the public dissemination of the stable series and will make it available to sponsors only. The test series, unfit in our view for production use, will however continue to be available to the public to avoid impact to the Gentoo Hardened and Arch Linux communities. If this does not resolve the issue, despite strong indications that it will have a large impact, we may need to resort to a policy similar to Red Hat's, described here or eventually stop the stable series entirely as it will be an unsustainable development model. ]]> culture gpl linux opensource security grsecurity via:nelson gentoo arch-linux gnu https://pinboard.in/ https://pinboard.in/u:jm/b:53dd8bf92d26/ 2015-07-29T22:09:50+00:00 http://www.r2d3.us/visual-intro-to-machine-learning-part-1/ jm decision-trees dataviz via:nelson d3 ml machine-learning https://pinboard.in/ https://pinboard.in/u:jm/b:413f321ce528/ 2015-07-29T16:32:57+00:00 http://blog.newegg.com/newegg-vs-patent-trolls-when-we-win-you-win/ jm via:nelson ip law patent-trolls patents newegg crypto https://pinboard.in/ https://pinboard.in/u:jm/b:918461047bb6/ 2015-06-07T20:26:53+00:00 https://blog.filippo.io/how-plex-is-doing-https-for-all-its-users/ jm via:nelson https ssl tls certificates pki digicert security plex https://pinboard.in/ https://pinboard.in/u:jm/b:32dbef75e47d/ 2015-04-26T21:21:57+00:00 http://googleonlinesecurity.blogspot.ie/2015/04/a-javascript-based-ddos-attack-as-seen.html jmWe hope this report helps to round out the overall facts known about this attack.

Had the entire web already moved to encrypted traffic via TLS, such an injection attack would not have been possible. This provides further motivation for transitioning the web to encrypted and integrity-protected communication. Unfortunately, defending against such an attack is not easy for website operators. In this case, the attack Javascript requests web resources sequentially and slowing down responses might have helped with reducing the overall attack traffic.

Using this technology, they will intercept all DNS lookup requests (TCP/UDP port 53) and transparently proxy the results. This effectively forces you to use their DNS service for all DNS lookups. If you have changed your DNS settings to an open DNS service such as Google, Comodo or OpenDNS expecting that your DNS traffic is no longer being sent to your ISP's DNS server, you may be surprised to find out that they are using transparent DNS proxying.
