  11. Not surprising. on NVIDIA's New GPUs Are Very Open-Source Unfriendly · · Score: 1

    Since the very reason given since the discussions began 15 or so years ago, Nvidia, and most of its competitors (Intel being a special exception for an unrelated reason) have always said that due to fears and concerns about reverse engineering, they - Nvidia and ATI, now AMD, have been slow and limited in making available any documentation or assistance that could directly or indirectly ease reverse engineering of its technology, its intellectual property (IP); not to Open Source / Free Software developers, but to potential and current 3D video card competitors.

    Providing the direct firmware blobs, even if encrypted (to be decrypted in memory on the video card) does reduce the effort of a reverse engineering attempt. Perhaps legal or senior management has overruled the previous plan to make encrypted firmware blobs. I believe there was one or more blogs entries written about methodologies of bypassing the decryption of encrypted firmware blobs even when/if the decryption key(s) are secure stored in the Nvidia GPU, or at least recovering the decryption key which undoes a lot of work by Nvidia, and may cause violate terms of various patent / IP licensing agreements.

    Nvidia could possibly go out of business if they were barred from obtaining necessary licenses allowing them to implement video codecs in hardware in their future products.

    I suspect this, or some benign reason (Nvidia's Linux developer were simply busy with in-house development, or on holiday) is the culprit.

    * Unrelated pure speculation:

    My pet theory about why Intel has been so open with their open source driver support for Linux, is that it is intended to be a) to support their APU processors and b) to try to help AMD in its secondary market (video GPUs) rather than their primary market (x86 compatible processors) which Intel knowns AMD needs to keep being a viable option, as AMD's x86 processors alone the past few years could of easily drove it out of business.

    To avoid more anti-trust violations / investigations Intel needs at least one viable x86 competitor to remain alive. Preferably neither too far ahead nor behind, so that Intel continues to dominate the CPU manufacturing sector, it has at least something that is realistically a potential threat to their business. Just not a strong potential threat. But by possibly supporting AMD's secondary product line by providing an open book to their GPU's documentation and interface via their driver source code, Intel can provide a subtle nod to technologies, or other solutions that AMD could re-implement to improve their (AMD's) video card offerings.

    In summary Intel can stand to help AMD in their video cards to keep AMD alive, which serves a critical purpose to Intel, as Intel needs someone that can be seen as potentially a rival CPU manufacturer.

    Regarding Intel's domination of microprocessors:

    While ARM processors have shipped in record numbers the past few years, they are manufactured by various companies who pay ARM a royalty (per unit made AFAIK), so Intel remains the single largest designer and manufacturer of CPUs. Although ARM Inc. has experienced explosive growth and tremendous profitability, it is still a tiny company in relative terms, such as market capitalization (a common benchmark) compared to Intel.

    but other countries complaining about the NSA is hypocrisy

    So you think the rest of the world should just accept the illegal (in the rest of the world) spying that the NSA does to them, just because it's a foreign government? That's a foolish argument.

    It is hypocritical to continuous publicly call a nation an ally, often pressuring them them into working with US on fighting terrorism, etc., and then spy on said government who practises what US calls good governance, i.e. an independent government consisting of democratically elected representatives. That's the part of hypocrisy in foreign affair approach of US that upsets people from the rest of the world. That and the fact they do it even when there is no evidence or even fear of hostile or undemocratic activity.

    if i was [G]erman, would i be worried about the NSA? or the BND and the BfV?

    Why should any law-aiding, peaceful, democracy supporting person in the world be subjected to espionage?

    if you live in a country outside the USA, and your biggest privacy concern is the NSA, you're a moron: your own country is doing everything the NSA is doing, and in many countries, far worse. obviously, they can also abuse you a lot easier than the USA can. and they do

    Actually in most of world the intelligence agencies are limited to investigate suspects of terrorism, and international criminal activities, not whatever they feel like. While unlawful and unreasonable spying does happen, the democratic governments do try to limit the powers of their intelligence agencies. Economic espionage is regarded as an illegal activity, even though numerous countries have been found to be engaged in it, it is still considered wrong.

    No other country in the world has an intelligence community even half the size of US. The Americans have always complained about allegedly Russians and Chinese spying on UN activities during negotiations, etc., but I doubt the Soviets ever managed a fraction of the spying the US conducted on the UN representatives.

    It is quite rational to be considered with being spied upon by all parties, foreign and domestic. The idea that US is somehow above the law when dealing with other countries in one of the prime reasons the US suffers from poor public image internationally, it undermines the massive good the US also does do in many cases.

    again: i don't have a problem with americans complaining about the NSA. americans SHOULD complain about the NSA. but i do have a problem with other countries complaining about the NSA when they do the same or worse

    Do people also not have the right to complain about fascist governments, because they didn't elect them? Do Americans have no right to be opposed to ISIL / ISIS because they are not primarily active within US?

    Why should you complain about what others complain about? Or are not a supporter and believer in free speech? It is one of those so-called key "American values" in theory.

    The part that is concerning is the existence of classified "experiments" where is it not clear what information is being gathered, who has access to it, and how it is being used.

    History has repeatedly shown that undisclosed, and/or unchecked surveillance ends up being misused against the public, not in the public interest.

    If everything is legal, robust, and accurate, why does law enforcement has to be done in such a clandestine manner? The vast majority of identification / evidence techniques used in court are robust enough to withstand being challenged by the defence.

  16. In case people are confused it is important to point out that the Titan cards aren't aimed at gamers.

    Yes, the Titan series is an odd bridge between consumer price/ performance, and professional reliability (ECC RAM) and unhampered double precision performance at painfully professional level prices of the CUDA / GPGPU oriented Quadro and Telsa cards. (Telsa K20 to K80 cost $3500 - $5000 USD approx AFAIK)

    So they are great alternatives for CUDA aware 3D graphics application users who traditionally can't afford a Quadro or Telsa card (are not professional movie / video-game studio artists or CAD designers), and students and researchers looking for low(er)-cost prototypes for developing CUDA / GPGPU software / experience. I assume any graduate CS/EE student studying parallelism / many-core hardware or software wants a Titan as an affordable alternative to the tuition-like pricing of the Quadro and Telsa cards.

    I had considering putting the Titan X on my own personal wish list, until I read that the FP64 isn't in line with performance improvements over previous generation Titans.

  19. Re:Protocol vs software that implements it on NTP's Fate Hinges On "Father Time" · · Score: 1

    The summary makes the mistake of conflating the NTP protocol with the messy NTP software developed by ntp.org.

    .
    Hopefully the ntp.org software fades away.

    However, the Network Time Protocol should live on in more secure and more easily maintained implementations (e.g., NTimed and OpenNTPd).

    Except that there is not one other fully-featured NTP client/server software system that I know of.

    Half of the so called "NTP clients" are really S-NTP clients (Simple NTP) that are barely if at all better than using the ancient BSD rdate command to jerk the time forward or back (whichever is needed) in a discontinuous fashion, that can cause gaps in logs, missing time-based trigger events from being fired, and other well-known woes.

    As far as I know PHK doesn't pretend that Ntimed is finished or fully functional. As far as I know it also doesn't pretend to support a large amount of "legacy" systems that still exist within companies networks, even if the vendor(s) disappeared 20 years ago in some cases. OpenNTPd is a pure network client/server system that AFAIK does not support external or master references (i.e. Cesium clocks or GPS modules) so while it may serve the purpose for a large number of users, it still depends on the continued operation of NTP.org's NTP software which is the de facto evolution of David Mill's reference implementation that was not intended to be a global or even enterprise-grade critical infrastructure project, but his research implementation as he, his colleagues, and students researched time synchronization.

    Some of NTPd's problem are that a) it has been maintained in a hap-hazarded fashion for 15 years longer than it should have been. b) any system where a single individual is critical or irreplaceable is broken. c) NTPd has been weak in release management / engineering for a long time now, and Stenn's ad-hoc approach hasn't done much to make the work easier for himself. I admit I had not realised that the software project, NTPd, has fallen into depending on a single person. I fact I thought the ISC (Internet Systems Consortium, the group that also maintain BIND, the most common Unix DNS server on the Internet) partnership was more than a means of managing payment and offering a few servers, I thought it was intended to take NTPd, like BIND, and make it into a healthy development community, revitalize the documentation, and share expertise in maintaining a critical infrastructure scale project Open Source of Free Software ecosystem.

    The most important yet non-technical solution is for Harlan Stenn to extract himself from being a critical piece of the NTPd software development and release process. IMHO he should focus 100% of his time on mentoring others to take over the various roles he is currently doing himself, and documenting the not so obvious knowledge about the protocol, its implementation, and the history surrounding pieces of code, to preserve his own knowledge, and what he can of David Mill's knowledge that isn't currently enshrined in Mill's papers and technical notes.

    Perhaps like OpenBSD that had to learn the hard way many years ago, companies can be leery (wisely from a legal point of view) of funding a seemingly one-man controlled Open Source project. Legally it may open up the possibility of being considered illegally hiring an employee in some jurisdictions ("perma-temps" or "consultants as de facto employees"), as it serves to primarily fund ongoing work that does benefit the sponsor either for their in-house or their product/service offerings.

    I have no ill feelings for or any dislike of Harlan Stenn. In fact I suspect he has unwittingly painted himself into a corner, and is now approaching the breaking point. And I believe the solution is radical, but not necessarily financially or technically challenging.

    Greenwich Mean Time is a known source of reliable time, as is the US Naval Observatory. Their time is based on the solar day -- the time it takes for the earth to complete a rotation in its orbit. NTP consults UTC or Universal Coordinated Time, which is Greenwich Mean Time expressed in the military's 24:00:00 hours terms.

    On a daily basis, NTP also consults atomic clocks, which tick off precise seconds based on radioactive Cesium-133 decomposition. A GPS receiver can be tied into an NTP server, and use the transmission of a GPS satellite to get the correct atomic time. A GPS satellite has three atomic clocks, so if one falls out of synch, the other two can overrule it and keep the system on track. For GPS time to be off by a billionth of a second means its answer to a location query will be off by a foot. So GPS relies on precisely counted time, not the solar day.

    Wow, that's so bad I'm not sure where to start; "Greenwich Mean Time" is a) a timezone still used by the UK when "British Summer Time" is not in effect, and is similar but not the same as UTC "Universal Coordinated Time" timezone, c) based upon the mean solar time at the Royal Observatory in Greenwich, London, UK.

    UTC "Universal Coordinated Time" is the present day global standard time reference (yes damnit that is the correct English name, in French "temps universel coordonné" or unofficially "Universel Temps Coordonné" with an unofficial English name of "Universal Time, Coordinated" to keep the abbreviation similar to UT0, UT1, etc.).

    The "military time" (i.e. 24-hour clock) reference is nonsense, and ignore 24-hour clock usage in civilian European life, and as well as being standard in anything time oriented.

    NTP is references to UTC, but UTC is in fact itself coordinated globally by about 80 national labs that operate their own national time references (typically 3 or more Cesium based time references, larger labs include hydrogen masers) which is coordinated by BIPM (International Bureau of Weights and Measures located in France). They work with International Astronomical Union (IAU) for things like determining when leap seconds are necessary to keep errors minimal. The largest contributors (by clock sources) are the US National Institute of Standards and Technology (NIST), US Naval Observatory, and the UK National Physics Laboratory (NPL) as I recall. The UK NPL and US NIST being pioneers in Cesium (Caesium) clocks.

    GPS has become the dominate, and preferable means of professional time synchronizations over distance due to the presence of rubidium or caesium references on board the GPS satellites themselves, and the proliferation of low-cost, widely-available GPS receiver modules including time-synchronisation models with 10s of nanosecond or better accuracy (uncertainty). This means GPS has also become the preferred means of high quality synchronization of NTP "masters" or low stratum references. -- The under-noted point that GPS's geo-location functionality requires a high precision time synchronization between the multiple satellites to determine a position with any amount of accuracy (bounded uncertainty).
