How Qualcomm Shook Down The Cell Phone Industry For Almost 20 Years

by Lawrence D'Oliveiro

A pretty sobering read <https://arstechnica.com/tech-policy/2019/05/how-qualcomm-shook-down-the-cel…>: Qualcomm's first weapon against competitors: patent licensing terms requiring customers to pay a royalty on every phone sold—not just phones that contained Qualcomm's wireless chips. Sound familiar? Judge Koh draws a direct parallel to licensing behavior that got Microsoft in legal trouble in the 1990s. Microsoft would offer PC makers a discount if they agreed to pay Microsoft a licensing fee for every PC sold—whether or not the PC shipped with a copy of MS-DOS. This effectively meant that a PC maker had to pay twice if it shipped a PC running a non-Microsoft operating system. There’s a lot more--the article reads like a catalogue of gangster-like tactics. All of which is perfectly all right under the US interpretation of “Free Enterprise”, of course ... Also, reading the details of how Qualcomm managed to sabotage Intel’s efforts to develop 5G chips, it seems to me that Qualcomm is directly responsible for the situation today where US companies are lagging behind Chinese ones like Huawei in 5G capability.

Edge TV Now Online-Only

by Lawrence D'Oliveiro

If there is anybody else besides me who wondered what happened to Edge TV, as of the beginning of this month it is no longer on Freeview, it can now only be viewed as an online stream <https://www.stuff.co.nz/entertainment/tv-radio/113928839/the-edge-tv-remove…>. In the last few days of June, there was a promo announcing that it was going HD, but I don’t recall it mentioning that it was leaving the broadcast airwaves. Quote: MediaWorks chief executive Michael Anderson says the move is in line with audience trends, which show people primarily consume music videos online. While that may be mostly true, personally I would go look for videos on YouTube after seeing them first on Edge TV.

The State Of Video Streaming In NZ

by Lawrence D'Oliveiro

Apple’s TV+ streaming service is coming soon, followed by Disney’s one <https://www.nzherald.co.nz/business/news/article.cfm?c_id=3&objectid=122666…>. Note: Disney+ will break Sky's longtime near-monopoly on Disney content in these parts. Disney says that, ultimately, Disney+ will be the exclusive home of its content. So to get a comparable range of TV content to that you currently have free-to-air, you are going to have to subscribe to two or three or maybe more different streaming services. The increasing multitude of things to pay for isn’t about choice, but about no choice at all.

Mozilla Moves To Monetize Thunderbird, Transfers Project To New Subsidiary

by Peter Reutemann

'The Mozilla Foundation announced today that it was moving its Thunderbird email client to a new subsidiary named the MZLA Technologies Corporation. From a report: Mozilla said that Thunderbird will continue to remain free and open source, but by moving the project away from its foundation into a corporate entity they will be able to monetize the product and pay for its development easier than before. Currently, Thunderbird is primarily being kept alive through charitable donations from the product's userbase. "Moving to MZLA Technologies Corporation will not only allow the Thunderbird project more flexibility and agility, but will also allow us to explore offering our users products and services that were not possible under the Mozilla Foundation," said Philipp Kewisch, Mozilla Product Manager. "The move will allow the project to collect revenue through partnerships and non-charitable donations, which in turn can be used to cover the costs of new products and services," Kewisch added.' -- source: https://tech.slashdot.org/story/20/01/29/1430253 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

64-Bit Times On 32-Bit Linux

by Lawrence D'Oliveiro

Some more patches have gone into the Linux kernel <https://www.theregister.co.uk/2020/01/30/linux_5_6_2038/> to allow 32-bit builds to deal with times past the year-2038 barrier. Basically the fix involves offering a 64-bit alternative to the original time_t type, without the whole app having to go 64-bit. One point I noticed is that certain filesystems (e.g. ext2, presumably ext3 as well) store on-disk fields with 32-bit timestamps, so if you’re using one of these, you’ll have to reformat the disks as well. And that would apply even if you’re already using a 64-bit OS.

autoremove

by john

Hi all, At our last meeting Tom was concerned about Linux bloating with surplus files. I have always found this to seldom be the case due to : a. The new download removes the older files or: b. The command autoremove clears the unused kernels and other not required files. eg. john@polomint:~$ sudo apt autoremove Reading package lists... Done Building dependency tree Reading state information... Done The following packages will be REMOVED: linux-headers-4.15.0-72 linux-headers-4.15.0-72-generic linux-image-4.15.0-72-generic linux-modules-4.15.0-72-generic linux-modules-extra-4.15.0-72-generic 0 upgraded, 0 newly installed, 5 to remove and 4 not upgraded. After this operation, 332 MB disk space will be freed. Do you want to continue? [Y/n] Cheers John..

Intel Is Patching Its 'Zombieload' CPU Security Flaw For the Third Time

by Peter Reutemann

'For the third time in less than a year, Intel has disclosed a new set of vulnerabilities related to the speculative functionality of its processors. On Monday, the company said it will issue a software update "in the coming weeks" that will fix two more microarchitectural data sampling (MDS) or Zombieload flaws. This latest update comes after the company released two separate patches in May and November of last year. Compared to the MDS flaws Intel addressed in those two previous patches, these latest ones have a couple of limitations. To start, one of the vulnerabilities, L1DES, doesn't work on Intel's more recent chips. Moreover, a hacker can't execute the attack using a web browser. Intel also says it's "not aware" of anyone taking advantage of the flaws outside of the lab. In response to complaints of the company's piecemeal approach, Intel said that it has taken significant steps to reduce the danger the flaws represent to its processors. "Since May 2019, starting with Microarchitectural Data Sampling (MDS), and then in November with TAA, we and our system software partners have released mitigations that have cumulatively and substantially reduced the overall attack surface for these types of issues," a spokesperson for the company said. "We continue to conduct research in this area -- internally, and in conjunction with the external research community.' -- source: https://it.slashdot.org/story/20/01/27/2126231 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

European Processor Initiative

by Lawrence D'Oliveiro

Here’s a report <https://www.nextplatform.com/2020/01/27/european-processor-initiative-readi…> on a Europe-wide effort to produce a processor chip for an “exascale” supercomputer. It will have an ARM CPU core, with a RISC-V-based accelerator and a few other special-purpose units on the side. I was intrigued to see mention of an “AI-inspired bfloat16 format”. Floating-point numbers commonly come in 32-bit and 64-bit sizes. There is also a “half-precision” 16-bit format, with reduced precision and dynamic range, commonly used in computer graphics, for example. This new format keeps the full dynamic range of 32-bit floats, at the expense of even further reduced precision. Apparently this works better for various machine-learning algorithms.

ProtonVPN Open Sources All Its Code

by Peter Reutemann

'ProtonVPN open sourced its code this week, ZDNet reports: On Tuesday, the virtual private network (VPN) provider, also known for the ProtonMail secure email service, said that the code backing ProtonVPN applications on every system -- Microsoft Windows, Apple macOS, Android, and iOS -- is now publicly available for review in what Switzerland-based ProtonVPN calls "natural" progression. "There is a lack of transparency and accountability regarding who operates VPN services, their security qualifications, and whether they fully conform to privacy laws like GDPR," the company says. "Making all of our applications open source is, therefore, a natural next step." Each application has also undergone a security audit by SEC Consult, which ProtonVPN says builds upon a previous partnership with Mozilla... The source code for each app is now available on GitHub (Windows, macOS, Android, iOS). "As a community-supported organization, we have a responsibility to be as transparent, accountable, and accessible as possible," ProtonVPN says. "Going open source helps us to do that and serve you better at the same time." They're also publishing the results of an independent security audit for each app. "As former CERN scientists, publication and peer review are a core part of our ethos..." the company wrote in a blog post. They also point out that Switzerland has some of the world's strongest privacy laws -- and that ProtonVPN observes a strict no-logs policy. But how do they feel about their competition? "Studies have found that over one-third of Android VPNs actually contain malware, many VPNs suffered from major security lapses, and many free VPN services that claimed to protect privacy are secretly selling user data to third parties."' -- source: https://yro.slashdot.org/story/20/01/27/0352244 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
