Ubuntu 21.04 will no longer be left / read by other users
With the release of Ubuntu on April 21, the bad practice in the Ubuntu universe will end when it was
/home the new user directory is created by default with 755 rights, ie readable for other regular users in the system. The novelty will be limited to 750. Ubuntu users’ complaints about overly open default settings date back to 2006, Canonical said, arguing that this facilitates data exchange between users of the same machine. Of course, rights can be set at will today as well as in the future.
Pat Gelsinger: We need to make a better CPU than the company to live in Cupertino
In less than a month, Pat Gelsinger will return to Intel as CEO, “Supreme Railway Engineer.” is involved in Intle and mentioned at a recent meeting with Intel employees in Oregon that the company “The computer ecosystem must deliver better products than anything the Cupertino-based life company can say.”.
The allusion is clear, for Intel, Apple’s transition to its own processors is a very painful blow, and its causes are the main thing Pat Glesinger will deal with. An allusion to Apple as a lifestyle company is quite appropriate. Despite its technology evolving at Apple, one constant holds true: Apple sells products for life at premium prices, and all of this is primarily susceptible. In Gelsinger’s eyes, Intel had, has, and will undoubtedly have a different mission.
Whether it will succeed will be seen in the years to come. We now have fresh Intel Tiger Lake processors, resp. Rocket Lake for the LGA1200 (just moving to market), the legs will still be Alder Lake for the LGA1700, but it’s all still a legacy of a miserable 14nm period. So let me suggest the following: let Pat Gelsinger give him 2 years to at least show what Intel has come up with and what it will launch soon, or put it directly on the market. Around mid-2023, it will be quite clear whether Intel with its old-new leader has managed to reverse current developments. But one thing we can be sure of: it won’t be a boring two years.
Current Seagate plan: 40% additional hard drive capacity within two years
Seagate recently unveiled its first 20TB hard drive (a standard-height 3.5-inch drive, of course), and its leaders are already making progress in the comments. Within two years, we should expect more than a 40% increase in the capacity of this manufacturer, which should be understood as an increase in capacity to about 30 TB in 2023, and then in 2026 to 50 TB. The current new 20 TB model represents the first proper use of thermally realized HAMR magnetic recording technology, so it can be concluded that rapid capacity growth will be on the shoulders of further development of HAMR technology.
By the way, the average capacity of the HDD in 2018 was 2.2 TB, in 2019 already 2.8 TB, and last year 3.7 TB (I personally bought a 4TB drive, which replaced the two deceased 2TB drives a few years old) ).
Rav1e 0.4 a little faster, but still not much against SVT-AV1
A new version of the AV1 encoder Rav1e 0.4.0 has been released. The creators have re-added some optimizations to make the compression work faster, but it’s still true that for the x86-64 / AVX2 / AVX512 the highly optimized Intel SVT-AV1 encoder is significantly faster (a review of existing measurements on Phoronix). Version 0.4 adds support for black and white video, API or 4: 2: 2 sampling enhancements, memory management optimizations, faster creation, and bug fixes.
TSMC is investing billions of dollars in the process on the road to risky 3 nm production
The production of 7nm FinFET / EUV process at TSMC is already a common routine, the company started mass production of 5nm EUV process (Apple M1, etc.) many weeks ago, so it is clear what will follow. TSMC is not slowing down, but this year intends to start risky production of the 3nm EUV process (the first variant of the production process called N3), and serial production will begin in the second half of 2022.
The company also increased its spending estimate from $ 20-22 billion to $ 25-28 billion. Asked directly whether this increase was due to Intel’s orders, the head of TSMC only said the company does not comment on specific customers or orders.
More and more work is being done to support customers in the production of various forms of chips. We also know that TSMC will invest more than $ 15 billion this year in the development of 3nm technology. It can be assumed that Apple will again be among the first customers. The company then expects a record Q1 / 21 in terms of revenue.
Large Intel Xe DG2 graphics will be produced by the 7nm process at TSMC
Reuters already reports that, according to available information, Taiwanese TSMC will ensure the production of the GPU of the large graphics card Intel Xe “DG2” with a new version of the 7nm process. A card built on DG2 should appear on the market sometime in the transition from 2021 to 2022, or more or less in a year, in the price range of $ 400 to $ 600.
Linux 5.12 allows you to disable Intel GPU security patches
It will be possible to manually disable patches for security holes in the Intel GPU (iGPU Leak) with Linux 5.12 kernel. A parameter is used for this
i915.mitigations=, and the default kernel settings will have these protections active. Recall that the errors relate to the last few generations of Intel GPUs, recently the repair itself was fixed for a 22nm generation Haswell CPU.
Nouveau receives initial support for the GeForce RTX 3000
The Nvidia Ampera generation is now supported in the open Nouveau driver, relevant patches have been delivered and approved. Of course, this is support for the very basic, basically just adjusting the kernel mode, without 3D acceleration. But it’s so important that Linus Torvalds broke the rule of not including new stuff in a particular version of the kernel after it was frozen, and with the support of GeForce RTX 3000 we can already find that in Linux 5.11.
- Fujifilm is finishing production of the professional Fujifilm Pro 400H paint negative. Based on the level of customer demand, the production of 35mm film will end in January, while the format of roll 120 will remain in production throughout 2021. The reason this time is not a strong drop in sales, but the fact of obtaining raw materials and therefore it is not possible to continue production. I remind you historically that Fujifilm stopped production of a number of popular Velvia / Provia reverse films a long time ago, also the production of the negative color Superia 1600 and the cult black and white negatives Neopan 1600 and Neopan Acros 100 (which was returned in the new version of the emulsion, but the price is crazy) .
- Netlix as a workaholic Hollywood studio? The internet giant plans one film premiere each week for this year. The epidemic situation in the world, and especially in the US, of course puts it on the cards: people are sitting more at home and, especially in the US, consuming much more internet content.
- The implementation of the DisplayPort 2.0 interface will appear only at the end of this year, or a year later compared to the original plans. According to VESA, the Sars-Cov2 pandemic is to blame, which has disabled the implementation of PlugTest events, at which the IT world agrees on standard implementations. Usually VESA organizes several such events a year, but none took place last year. The first could be this spring, however, let’s not expect a device with DisplayPort 2.0 support until the second half of this year.
- AMD is starting to talk more about the architecture of the Zen 4 processor. This will mean the transition from AM4 to AM5, support for DDR5 and USB 4.0. We don’t yet know how much an increase in IPC can be expected, but TSNC will produce 5 nm and it is generally assumed that AMD could increase the number of CPU cores in the chips (there are currently 8 / chiplet). Zen 4 family products should appear later this year.
