I asked teachers to tell me how AI has changed how they teach.

The response from teachers and university professors was overwhelming. In my entire career, I’ve rarely gotten so many email responses to a single article, and I have never gotten so many thoughtful and comprehensive responses.

One thing is clear: teachers are not OK.

They describe trying to grade “hybrid essays half written by students and half written by robots,” trying to teach Spanish to kids who don’t know the meaning of the words they’re trying to teach them in English, and students who use AI in the middle of conversation. They describe spending hours grading papers that took their students seconds to generate: “I've been thinking more and more about how much time I am almost certainly spending grading and writing feedback for papers that were not even written by the student,” one teacher told me. “That sure feels like bullshit.”

"this morning, as I was finishing up work on a video about a new mini Pi cluster, I got a cheerful email from YouTube saying my video on LibreELEC on the Pi 5 was removed because it promoted:

Dangerous or Harmful Content Content that describes how to get unauthorized or free access to audio or audiovisual content, software, subscription services, or games that usually require payment isn't allowed on YouTube.

I never described any of that stuff, only how to self-host your own media library.

This wasn't my first rodeo—in October last year, I got a strike for showing people how to install Jellyfin!

In that case, I was happy to see my appeal granted within an hour of the strike being placed on the channel. (Nevermind the fact the video had been live for over two years at that point, with nary a problem!)

So I thought, this case will be similar:

• The video's been up for over a year, without issue
• The video's had over half a million views
• The video doesn't promote or highlight any tools used to circumvent copyright, get around paid subscriptions, or reproduce any content illegally

Slam-dunk, right? Well, not according to whomever reviewed my appeal. Apparently self-hosted open source media library management is harmful.

Who knew open source software could be so subversive?"

Vcc - the Vulkan Clang Compiler, is a proof-of-concept C and C++ compiler for Vulkan leveraging Clang as a front-end, and Shady our own research IR and compiler. Unlike other shading languages, Vcc aims to stick closely to standard C/C++ languages and merely adds a few new intrinsics to cover GPU features. Vcc is similar to CUDA or Metal in this regard, and aims to bring the advantages of standard host languages to Vulkan shaders.

Key Features

Vcc supports advanced C/C++ features usually left out of shading languages such as HLSL or GLSL, in particular raising the bar when it comes to pointer support and control-flow:

• Unrestricted pointers
  • Arithmetic is legal, they can be bitcasted to and from integers
• Generic pointers
  • Generic pointers do not have an address space in their type, rather they carry the address space as a tag in the upper bits.
• True function calls
  • Including recursion, a stack is implemented to handle this in the general case
• Function pointers
  • Lets you write code in a functional style on the GPU without limitations
• Arbitrary goto statements - code does not need to be strictly structured !

Many of these capabilities are present in compute APIs, but are not supported in most graphics APIs such as DirectX or Vulkan. We aim to address this gap by proving these features can and should be implemented. More on why we think that’s important.

Open-source RISC-V cores are increasingly demanded in domains like automotive and space, where achieving high instructions per cycle (IPC) through superscalar and out-of-order (OoO) execution is crucial. However, high-performance open-source RISC-V cores face adoption challenges: some (e.g. BOOM, Xiangshan) are developed in Chisel with limited support from industrial electronic design automation (EDA) tools. Others, like the XuanTie C910 core, use proprietary interfaces and protocols, including non-standard AXI protocol extensions, interrupts, and debug support.

In this work, we present a modified version of the OoO C910 core to achieve full RISC-V standard compliance in its debug, interrupt, and memory interfaces. We also introduce CVA6S+, an enhanced version of the dual-issue, industry-supported open-source CVA6 core. CVA6S+ achieves 34.4% performance improvement over CVA6 core.

We conduct a detailed performance, area, power, and energy analysis on the superscalar out-of-order C910, superscalar in-order CVA6S+ and vanilla, single-issue in-order CVA6, all implemented in a 22nm technology and integrated into Cheshire, an open-source modular SoC. We examine the performance and efficiency of different microarchitectures using the same ISA, SoC, and implementation with identical technology, tools, and methodologies. The area and performance rankings of CVA6, CVA6S+, and C910 follow expected trends: compared to the scalar CVA6, CVA6S+ shows an area increase of 6% and an IPC improvement of 34.4%, while C910 exhibits a 75% increase in area and a 119.5% improvement in IPC. However, efficiency analysis reveals that CVA6S+ leads in area efficiency (GOPS/mm2), while the C910 is highly competitive in energy efficiency (GOPS/W). This challenges the common belief that high performance in superscalar and out-of-order cores inherently comes at a significant cost in area and energy efficiency.

Industry committee of the European Parliament shows necessity and benefits of “open-source first” policy but report lacks concrete measures.

In April, Palantir co-founder Joe Lonsdale got into a brawl with former Coinbase chief technology officer and Network State advocate Balaji Srinivasan. It wasn’t on a prominent stage or even Twitter/X; it happened in a Signal group chat that’s become a virtual gathering place for influential tech figures. Srinivasan wasn’t going along with the tech right’s aggressive anti-China rhetoric, so Lonsdale accused him of “insane CCP thinking.” “Not sure what leaders hang out w you in Singapore but on this you have been taken over by a crazy China mind virus,” he wrote.

Before Semafor published its story on the Signal chats that led with the billionaire spat, both Lonsdale and Srinivasan dismissed any notion their exchange was anything but a friendly disagreement. Surely, such wealthy people have much more in common than they do separating them. But the exchange does expose an ideological rift that will likely only grow in the coming years as more of the tech industry openly aligns itself with the security state to pursue lucrative military contracts.

Lonsdale and Srinivasan are arguably on either side of that divide. Palantir is part of the vanguard of defense tech companies openly championing collaboration with the US government. It claims to want to defend American power in the twenty-first century, positioning China as a civilizational threat — in part to mask the commercial threat Shenzhen poses to Silicon Valley. Lonsdale was even helping staff the Trump administration. The Network State movement, on the other hand, wants to escape the authority of the United States — or any other government — entirely, and doesn’t feel it’s part of that fight.

There are more than a billion PCs in use and, according to StatCounter, only 71 percent of them run Windows. Among the rest, about 4 percent run Linux. That's tens of millions of people with Ubuntu, Mint, Debian, etc as their desktop operating system. I envy them.

Windows 11 has become more annoying lately as it shoves ads for XBox Game Pass in my face, pushes AI features no one asked for and demands that I reconsider the choices I made during installation on a regular basis. Plus, it just isn't that attractive.

I'm ready to try joining that industrious four percent and installing Linux on my computers to use as my main OS, at least for a week. I'll blog about the experience here.

It's hard to give up Windows forever because so many applications only run in Microsoft's OS. For example, the peripheral software that runs with many keyboards and mice isn't available for Linux. Lots of games will not run under Linux. So I think it's likely I'll be using Windows again, at least some of the time, after this week is through.

However, for now, I'm going to give Linux a very serious audition and document the experience.
