  • Unless it can be paper thin this does not look better than magnetic tape.

    As the article explains, the whole purpose here is to be able to store data on a medium that can endure harsh conditions, including heat, moisture, radiation, and physical abrasion. The company’s website claims the medium can retain data for 5000 years without power, and is water and fire resistant.

    I reckon you could scratch it pretty easily.

    The underlying ceramic film is already used for protecting tools like drill bits and saw blades from physical damage, which is why it was chosen for this project. They already found one of the most durable materials in the world, and asked whether they could store data using that already-durable material.



  • Motorola Mobility was spun off from Motorola in 2012 and sold to Google. Then Google sold it in 2014 to Lenovo, the Chinese company that had also previously bought IBM’s entire personal computer business.

    Original Motorola, renamed Motorola Solutions, retained the rights to the Motorola name in everything except cell phones, and continued to manufacture radio and communications equipment and other signal processing equipment (including stuff like cable TV boxes). They remain a major contractor for militaries, law enforcement, and fire/EMS emergency responders.

    If we’re talking about Motorola cell phones, we’re talking about the Chinese owned company, not the American owned company.




  • Apple supports its devices for a lot longer than most OEMs after release (minimum 5 years since being available for sale from Apple, which might be 2 years of sales), but the impact of dropped support is much more pronounced, as you note. Apple usually announces obsolescence 2 years after support ends, too, and stop selling parts and repair manuals, except a few batteries supported to the 10 year mark. On the software/OS side, that usually means OS upgrades for 5-7 years, then 2 more years of security updates, for a total of 7-9 years of keeping a device reasonably up to date.

    So if you’re holding onto a 5-year-old laptop, Apple support tends to be much better than a 5-year-old laptop from a Windows OEM (especially with Windows 11 upgrade requirements failing to support some devices that were on sale at the time of Windows 11’s release).

    But if you’ve got a 10-year-old Apple laptop, it’s harder to use normally than a 10-year-old Windows laptop.

    Also, don’t use the Apple store for software on your laptop. Use a reasonable package manager like homebrew that doesn’t have the problems you describe. Or go find a mirror that hosts old MacOS packages and install it yourself.


  • This write-up is really, really good. I think about these concepts whenever people discuss astrophotography or other computation-heavy photography as being fake software generated images, when the reality of translating the sensor data with a graphical representation for the human eye (and all the quirks of human vision, especially around brightness and color) needs conscious decisions on how those charges or voltages on a sensor should be translated into a pixel on digital file.


  • Cutting edge chip making is several different processes all stacked together. The nations that are roughly aligned with the western capitalist order have split up responsibilities across many, many different parts of this, among many different companies with global presence.

    The fabrication itself needs to tie together several different processes controlled by different companies. TSMC in Taiwan is the current dominant fab company, but it’s not like there isn’t a wave of companies closely behind them (Intel in the US, Samsung in South Korea).

    There’s the chip design itself. Nvidia, Intel, AMD, Apple, Qualcomm, Samsung, and a bunch of other ARM licensees are designing chips, sometimes with the help of ARM itself. Many of these leaders are still American companies developing the design in American offices. ARM is British. Samsung is South Korean.

    Then there’s the actual equipment used in the fabs. The Dutch company ASML is the most famous, as they have a huge lead on the competition in manufacturing photolithography machines (although old Japanese competitors like Nikon and Canon want to get back in the game). But there are a lot of other companies specializing in specific equipment found in those labs. The Japanese company Tokyo Electron and the American companies Applied Materials and Lam Research, are in almost every fab in the West.

    Once the silicon is fabricated, the actual packaging of that silicon into the little black packages to be soldered onto boards is a bunch of other steps with different companies specializing in different processes relevant to that.

    Plus advanced logic chips aren’t the only type of chips out there. There are analog or signal processing chips, or power chips, or other useful sensor chips for embedded applications, where companies like Texas Instruments dominate on less cutting edge nodes, and memory/storage chips, where the market is dominated by 3 companies, South Korean Samsung and SK Hynix, and American company Micron.

    TSMC is only one of several, standing on a tightly integrated ecosystem that it depends on. It also isn’t limited to only being located in Taiwan, as they own fabs that are starting production in the US, Japan, and Germany.

    China is working at trying to replace literally every part of the chain in domestic manufacturing. Some parts are easier than others to replace, but trying to insource the whole thing is going to be expensive, inefficient, and risky. Time will tell whether those costs and risks are worth it, but there’s by no means a guarantee that they can succeed.





  • It’s bizarre how if you drove through twenty bus stops in three days, you would not only lose your license but be in jail on multiple charges.

    This is a relatively unique Texas law that requires cars to stop when school buses are loading or unloading passengers, including on the opposite side of the road going the other direction. The self driving companies didn’t program for that special use case, so it actually is a relatively easy fix in software.

    And the human drivers who move to Texas often get tripped up by this law, because many aren’t aware of the requirement.
