The US crackdown on exports to Huawei now includes even stronger restrictions than the company has already faced. The Financial Times reports that Intel and Qualcomm have had their Huawei export licenses revoked, so Huawei will no longer be able to buy chips from either company.

The export ban has been around since 2020 and means that any company wishing to ship parts to Huawei must get approval from the government on a case-by-case basis. Sometimes these come with restrictions, like Qualcomm's license, which allowed it to ship smartphone chips to Huawei, but not "5G" chips. That led to Qualcomm creating special 4G-only versions of its 5G chips for Huawei, and the company ended up with 4G-only Snapdragon 888 phones in 2021.

Since then, Huawei has been working on its own Arm chips from its chip design division, HiSilicon. In April, the Huawei Pura 70 smartphone launched with an in-house HiSilicon Kirin 9010 SoC made at SMIC, a Chinese chip fab that is also facing export restrictions. With what is probably still a 7 nm manufacturing process, it's more of a 2020 chip than a 2024 chip, but that's still fast enough for many use cases.

There's a fundamental flaw in current car safety tech: It's limited to line of sight. Or, perhaps, line of "sensing" is more accurate, because the way cameras and lidar work is to inspect the perimeter of a vehicle and use predictive algorithms to understand the motion of an object in relation to the motion of the vehicle itself. Which is good, because as carmakers have added elements such as pedestrian and cyclist detection, they're trying to prevent drivers from hurting the most vulnerable road users. And unfortunately this is necessary, because even though 2023 saw a slight reduction in drivers striking cyclists and pedestrians, according to the most recent data from the Governor's Highway Safety Association, since 2019 pedestrian fatalities are still up 14 percent—and cyclist deaths are up 50 percent since 2010.

That doesn't mean lidar and cameras have "failed," but because they rely on what the sensors can pick up, they cannot necessarily ID hazards (and alert drivers) as quickly as we need them to, particularly if that's a cyclist in your lane 300 feet down the road, just over the next rise. Yes, current sensing works well now with figuring out the pace of a traffic jam, and automatic emergency braking can step in to stop your car if you fail to. But for non-automotive obstacles, they're still limited.

For that, we need better tech, which is emerging and is called Connected Vehicle to Everything (C-V2X). The idea isn't that complicated. Boiled down, it's a chipset that operates on a portion of the cellular bandwidth, and vehicles with this tech embedded (say in an e-bike or car) monitor anything with a C-V2X chip as well as broadcast their own location at a pulse of 10 times a second. This precision location system would then warn a driver of a cyclist on the road ahead, even beyond line of sight, and in an emergency—possibly because a cyclist was right in a car's path—could prevent a collision.

When Apple announced the Apple M4 chip during its iPad Pro event yesterday, it mentioned that the chip came with "up to" four high-performance CPU cores.

Those short, easily missable words always mean that there's a lower-end version of the chip coming that doesn't include that many CPU cores, and the tech specs page for the new iPad Pro has the full details: iPad Pros with 256GB or 512GB of storage use a version of the M4 with three high-performance CPU cores and six smaller efficiency cores. Only the models with 1TB and 2TB of storage have an M4 with all four high-performance CPU cores enabled.

The 256GB and 512GB models also ship with 8GB of RAM, where the 1TB and 2TB models come with 16GB of memory installed. Though these changes are clearly spelled out on the Tech Specs page, the actual configuration page for the iPad Pros in Apple's online store doesn't give any indication that upgrading storage also upgrades your CPU and RAM.

The Federal Communications Commission clarified its net neutrality rules to prohibit more kinds of fast lanes.

While the FCC voted to restore net neutrality rules on April 25, it didn't release the final text of the order until yesterday. The final text has some changes compared to the draft version released a few weeks before the vote.

Both the draft and final rules ban paid prioritization, or fast lanes that application providers have to pay Internet service providers for. But some net neutrality proponents raised concerns about the draft text because it would have let ISPs speed up certain types of applications as long as the application providers don't have to pay for special treatment.
