Code execution in deserializers should be disabled by default and only be enabled explicitly. In the latter case, the implementation should ensure (for example, via specific functions) that the code execution results in strictly bounded time/memory limits.
I also tested the Radxa USB-C PD 30W power adapter, which says it will output 5V at 5A, but the Pi only negotiates 3A with it right now. I've been in contact with Pi engineers and it seems like they have one on the way to test to see why it's not negotiating more.
I should also note the official adapter lists 12V at 2.25A output as an option, so maybe some future Pi could take that and run with it, for increased compatibility with more USB-C PD adapters (5V at 5A is a rarely seen, though it's an option in the spec).
雖然 Matt Mullenweg 在文章裡都沒提到,但 WordPress 的興起其實跟當年 2004 年最大的 blog 軟體 Movable Type 自己出的包有很大的關係:
With the release of version 3.0 in 2004, there were marked changes in Movable Type's licensing, most notably placing greater restrictions on its use without paying a licensing fee. This sparked criticism from some users of the software, with some moving to the then-new open-source blogging tool WordPress. With the release of Movable Type 3.2, the ability to create an unlimited number of weblogs at all licensing levels was restored. In Movable Type 3.3, the product once again became completely free for personal users.
當年 hlb 在社團主機上用 Movable Type 架了服務讓大家寫,結果後來發生了 license 問題,大家就都順勢跑到 WordPress 上了;而等到 Movable Type 再次想放寬 license 的時候已經來不及了,大家都已經搬完了。
Trainium-based EC2 Trn1 instances solve this challenge by delivering faster time-to-train while offering up to 50% cost-to-train savings over comparable GPU-based instances.
For large-scale model training, Trn1 instances integrate with Amazon FSx for Lustre high-performance storage and are deployed in EC2 UltraClusters. EC2 UltraClusters are hyperscale clusters interconnected with a non-blocking petabit-scale network.
但第一波開放的區域有點少,只有萬年美東一區 us-east-1 與美西二區 us-west-2:
You can launch Trn1 instances today in the AWS US East (N. Virginia) and US West (Oregon) Regions as On-Demand, Reserved, and Spot Instances or as part of a Savings Plan.
By the end of 2024, all mobile phones, tablets and cameras sold in the EU will have to be equipped with a USB Type-C charging port. From spring 2026, the obligation will extend to laptops.
Totally insane, in the best possible way. The EC2 and Nitro teams have created virtualized versions of the oldest (pre-Nitro) instance types that run on more modern hardware using the original PV AMIs!
All of these innovations enable us to continue to offer many of our older instance types well past the lifetime of the original hardware. Starting in 2022, customers launching M1, M2, M3, C1, C3, R3, I2 and T1 instances will land on Nitro supported instances hardware and existing running instances will also be migrated.
