Intel Fail: OpenBSD disables Intel HyperThreading, Lazy FP State Restore
by grarpamp 26 Jun '18

https://www.mail-archive.com/source-changes@openbsd.org/msg99141.html https://www.intel.com/content/www/us/en/security-center/default.html Mark Kettenis Tue, 19 Jun 2018 12:30:19 -0700 Log message: SMT (Simultanious Multi Threading) implementations typically share TLBs and L1 caches between threads. This can make cache timing attacks a lot easier and we strongly suspect that this will make several spectre-class bugs exploitable. Especially on Intel's SMT implementation which is better known as Hypter-threading. We really should not run different security domains on different processor threads of the same core. Unfortunately changing our scheduler to take this into account is far from trivial. Since many modern machines no longer provide the ability to disable Hyper-threading in the BIOS setup, provide a way to disable the use of additional processor threads in our scheduler. And since we suspect there are serious risks, we disable them by default. This can be controlled through a new hw.smt sysctl. For now this only works on Intel CPUs when running OpenBSD/amd64. But we're planning to extend this feature to CPUs from other vendors and other hardware architectures. Note that SMT doesn't necessarily have a posive effect on performance; it highly depends on the workload. In all likelyhood it will actually slow down most workloads if you have a CPU with more than two cores. ok deraadt@

Re: Persecution of Julian Assange Must End

This is a principle that is uncontroversial, that the state's actions against citizens must be limited and subject to open and transparent processes, not by a consensus of people selected to form the consensus, and that the government itself is not infallible (exemplified by the omniscient US government thinking Snowden was on a Bolivian plane). Of course Assange is an Ecuadorian citizen, so if they wanted to, they could have him leave the embassy through temporary diplomatic status, particularly since he isn't accused of any crime by the British. Naturally this won't happen, as he is a bargaining chip in the current system.

Saker interviews Michael Hoffman - definitive JQ author - [MINISTRY] [WAR]

** 'Orthodox Judaism Is a Religion of Lying and Deceit' - The Saker Interviews Michael Hoffman http://www.unz.com/tsaker/an-interview-with-michael-a-hoffman-ii/ https://russia-insider.us9.list-manage.com/track/click?u=fa2faf7034c3c3c413… ------------------------------------------------------------ by Michael Hoffman Unz Review (1,109 views) on Fri, Jun 22, 2018 Hoffman is author of the academic work 'Judaism's Strange Gods', amongst other books. Introduction by the Saker: I have always had a passion for theology in general and the studies of religions in general. Several years ago I discovered, quite by chance, a book written by Michael A. Hoffman II entitled Judaism’s Strange Gods https://www.amazon.com/Judaisms-Strange-Gods-Revised-Expanded/dp/0970378483… which I found most interesting and thought provoking. Reading that book, I felt that I wanted to find out much more and I ended up ordering and reading Michael A. Hoffman II’s magnum opus Judaism Discovered: A Study of the Anti-Biblical Religion of Racism, Self-Worship, Superstition and Deceit https://www.amazon.com/Judaism-Discovered-Anti-Biblical-Self-Worship-Supers… which absolutely amazed me: over 1000 pages packed with information, sources and most interesting analyses. Needless to say, the book was also very controversial and elicited all sorts of negative reactions from various reviewers. Here I need to immediately begin by a disclaimer: while the topic of “Rabbinical Phariseism” (modern “Judaism” should be called something like “Rabbinical Phariseism” since all modern Judaic denomination are descendants of the sect of the Pharisees; furthermore, this religion is dramatically different from the religion of Abraham, Isaac and Jacob: it is the religion of Maimonides, Karo, Luria and others) has always fascinated me and while I do have a graduate degree in theology, I am absolutely not qualified to endorse or refute the views of Hoffman. What I can say is that his books are very well written, well researched, fully sourced and that I see no contradictions between what he wrote and the little I personally know about this topic. As for his critique of the religion of the Rabbinical Pharisees (from which all form of modern “Orthodox Judaism” stem from), it is not “racist” in any way: unlike ethnicity, a ---religion is a personal choice and thus a legitimate target for scrutiny and criticism--- and Hoffman’s condemnation of Rabbinical Phariseism is in no way harsher than the writings of Church Fathers like Saint Justin Martyr, Saint John Chrysostome, Saint Cyprian of Carthage or Saint Ephrem the Syrian. Hoffman recently published another amazing book, the 700 pages long “The Occult Renaissance Church of Rome” https://www.amazon.com/Occult-Renaissance-Church-Rome/dp/0990954722/?tag=un… which I began reading (I am about 1/3rd through) with, again, rapt interest. Yet again, here was a very well researched and beautifully controversial book which gave me as strong desire to speak with the author and, luckily for me, Michael A. Hoffman II has kindly agree to replies to my questions to him on his life and research. The following is the full unedited Q&A with I had with him. … Enjoy...

Such attackers will have massive non recyclable energy cost, typically required to appear on their public sheets. Attackers will therein also resort to FUD plays easily proven false. And their ASICs broken by nonce changes in algos. Legit p2p webs of in person validated global trust nets will also develop creating new handshake agreements in mining / nodes defense, sybils will not be able to pass inspection up to and including SSBI style, large operations will be suspected and derated in metrics accordingly. Attackers are ultimately frail and cannot continue to forever inflate and sink their fiat into such attacks, citizens will revolt against that. Users will simply migrate and exchange away to more advanced and resistant usable cryptocurrency nets if attackers tx fees and etc begin making make the old unusable. ie: What has happened with downfall of BTC... Cryptocurrency, once established globally in trio of... philosophical mind, enough mechanical knowledge to use confidently, and then used routinely as desired... is wonderfully adaptive to attacks. Each of those three are inevitable and unstoppable, and they continue to increase, leading to eventual victory of cryptocurrency. The "established" will make more by accepting and servicing it than they will by burning resources trying to fight it. bcc cypherpunks because metz list is proven censored, resident anti cryptocurrency established friends / devs / etc of state, etc. Cryptocurrency.... what if....
