Notable new features

[Windows Update]

• As announced in the Windows Update announce blog, we are rolling out a new unified update experience to reduce the number of reboots you see per month. We are starting by coordinating driver, .NET, and firmware updates to align with the monthly quality update, reducing the update experience to a single monthly restart. See the blog for more information.

• Finding apps is more forgiving. Search is better at handling typos, dropped letters, extra letters, and partial words for apps. Queries like “utlook” can still find Outlook.
• Settings results are improving. We’ve made ranking improvements to help more relevant settings appear higher in results.

I have been looking at seL4 some more recently, and had a small patch merged today to remove a legacy Python module from a helper script. (I was trying to run the script on a system without that module installed, and it was almost easier to patch it out.)

However, the more I think about this code and how it’s used, the more it seems wrong on at least five other levels.

The patch itself is quite uninteresting; this script was importing the past module (part of future?) to use the xrange function. Python 2 used to have separate xrange and range functions, where range returned a list in memory while xrange generated an iterator. Because this seL4 script is iterating over a large range of values, it’s important the list is not generated in-memory. But Python 3 removed the xrange function and just has range return an object, so it’s trivial to avoid the module import.

Having thought carefully some more about the specific line, there’s surely an off-by-one error in it - range iterates over 0 to n-1, so this line shouldn’t be subtracting one if it’s looking to test all 32-bit values:

    for i in range(2**32-1):

But then again, this is being used for a ‘sanity check’ of a magic bit shift algorithm that speeds up division operations to convert CPU ticks to microseconds on 32-bit arm platforms. Surely if the algorithm’s good, it shouldn’t be necessary to validate it exhaustively against every possible 32-bit value?

Also, 32 bits isn’t enough, because this is 64-bit division. include/api/types.h shows that ticks_t is always a uint64_t, so if this were a proof by exhaustion it should run to 2**64 (though that would take infeasibly long).

As discussed in issue #1352, lots of people have been running this code with the wrong divisor anyway. But because the bit shift path is only used on 32-bit platforms, it’s not clear to me that there’s even any point in specifying CLK_SHIFT/MAGIC on platforms which are 64-bit only (e.g. the tx2 port).

And to follow this rabbit hole to the very end, in comments on PR #1435 and issue #1509 it’s clear that the future of this code is to remove it, as it’s 1. unnecessarily clever (on 64-bit platforms the equivalent code just uses a division, so performance can’t be that important), and 2. the entire concept of converting to microseconds breaks the seL4 principle of not abstracting away details of the hardware.

So this has left me unclear on whether my small patch was a good thing or not, but I certainly learnt something about this corner of seL4 timer handling. And I’ve ordered a copy of “Hacker’s Delight” on the recommendation of a code comment.

The diffoscope maintainers are pleased to announce the release of diffoscope version 319. This version includes the following changes:

Quite the opposite, because as you may know, if you use many of the existing chatbots, they're really focused on engagement to a large degree. And sycophancy, right? They kind of want to pull you in. They might encourage you to reveal things about yourself, and then use that as a basis to establish a connection.

We view it quite the opposite. I mean, the way that we have designed Siri, Siri really wants to say 'Listen, that's not what I'm here for, right? I'm here to help you. I can help you get things done. I can help you learn about the world.' But if you try to engage Siri as a romantic partner, Siri's not up for that. Siri's 100 percent not into that.

We like when technology disappears, right? You just focus on what you want to do, or you focus on the content. And it's the same thing with AI. [...] We don't do AI for AI's sake. 'Hey, look at us, we're doing AI.' It's how does AI make everything better? And that makes our products better, our features better.

I think it's a challenging thing for a lot of people to understand the distinction between what your iPhone knows and what, say, Apple as a company knows. Your iPhone is yours, right? Your data is yours and it stays on your phone and your control and Siri is using it for you. Apple doesn't get to know any of this stuff, and that is very different than I think most players in the space, and I think super important.

We strongly disagree with the Senate's consideration of European-style regulation that would hamper innovation and force changes consumers never asked for, while undermining the privacy, security and child safety protections they rely on every day. Apple is proud to be an engine of innovation, job creation, and economic growth in the U.S., where some of the world's most innovative companies have designed technology that has changed the world. Importing Europe's failed policies will not increase competition -- it will make it more difficult to do business right here at home.
