GitHub Copilot Is Moving To Usage-Based Billing

GitHub said in a blog post today that it is moving Copilot to usage-based billing starting June 1. Base subscription prices will remain the same but premium requests will be replaced with monthly AI Credits that are consumed based on token usage. "Instead of counting premium requests, every Copilot plan will include a monthly allotment of GitHub AI Credits, with the option for paid plans to purchase additional usage," the platform said. "Usage will be calculated based on token consumption, including input, output, and cached tokens, using the listed API rates for each model. This change aligns Copilot pricing with actual usage and is an important step toward a sustainable, reliable Copilot business and experience for all users." Documentation for individuals, businesses and enterprises, and an FAQ can be found at their respective links.

Microsoft To Stop Sharing Revenue With OpenAI

Bloomberg reports that Microsoft is ending revenue-sharing payments to OpenAI (paywalled; alternative source) and making the partnership non-exclusive. "The rapid pace of innovation requires us to continue to evolve our partnership to benefit our customers and both companies," Microsoft said Monday in a blog post. Bloomberg reports: The revised deal is meant to simplify a complicated relationship between two partners that has been foundational to OpenAI's rise and the broader AI boom. OpenAI has since pursued partnerships with multiple cloud providers, including Microsoft rival Amazon.com Inc., to meet its growing computing needs to build and service AI software to a wider audience. As part of OpenAI's restructuring last year as a for-profit business, Microsoft received a 27% ownership stake in the AI startup.

California's Billionaire Tax Has the Signatures to Make the Ballot

California's proposed billionaire tax appears headed for the November ballot after backers said they gathered more than 1.5 million signatures, well above the threshold needed to qualify. SF Standard reports: Backers of the initiative announced this weekend that more than 1.5 million people signed a petition to bring the one-time, 5% wealth tax to a statewide vote come November. That's well beyond the 875,000 names needed to qualify the measure, and likely sufficient to account for illegible or invalid signatures. The Service Employees International Union United Healthcare Workers West, a union representing more than 120,000 healthcare workers, pitched the tax to make up for federal spending cuts that threaten to shutter hospitals(opens in new tab) and kick millions of people off medical insurance. Proponents of California's wealth tax estimate it would raise $100 billion in one-time revenue, even if some billionaires leave because of the measure. The nonpartisan California Legislative Analyst's Office forecasts tens of billions in upfront revenue, but cautioned that the tax could cost hundreds of millions or more a year if some billionaires move out of state. The proposal, which needs a simple majority to pass, would apply to assets of people with net worth of $1 billion or more who lived in California as of Jan. 1 this year. That means it would affect about 200 people, according to the SEIU-UHW.

If 64bit Windows 11 contains a copy of 32bit explorer.exe, could you run it as its shell?

Raymond Chen published a blog post about how a crappy uninstaller on Windows caused a mysterious spike in the number of Explorer (Windows' graphical shell) crashes. It turns out the buggy uninstaller caused repeated crashes in the 32bit version of Explorer on 64bit systems, and - hold on a minute. The how many bits on the what now? The 32-bit version of Explorer exists for backward compatibility with 32-bit programs. This is not the copy of Explorer that is handling your taskbar or desktop or File Explorer windows. So if the 32-bit Explorer is running on a 64-bit system, it's because some other program is using it to do some dirty work. ↫ Raymond Chen at The Old New Thing So I had no idea that 64bit Windows included a copy of the 32bit Explorer for backwards compatibility. It obviously makes sense, but I just never stopped to think about it. This made me wonder though if you could go nuts and do something really dumb: could you somehow trick 64bit Windows into running this 32bit copy of Explorer as its shell? You'd be running 32bit Explorer on 64bit Windows using the 32bit WoW64 binaries where you just pulled the 32bit Explorer binary from, which seems like a really nonsensical thing to do. Since there's no longer any 32bit builds of Windows 11, you also can't just copy over the 32bit Explorer from a 32bit Windows 11 build and achieve the same goal that way, so you'd really have to go digging around in WoW64 to get 32bit versions. I guess the answer to this question depends on just how complete this copy of 32bit Explorer really is, and if Windows has any defenses or triggers in place to prevent someone from doing something this uselessly stupid. Of course, there's no practical reason to do any of this and it makes very little sense, but it might be a fun hacking project. Most likely the Windows experts among you are wondering what kind of utterly deranged new designer drug I'm on, but I was always told that sometimes, the dumbest questions can lead to the most interesting answers, so here we are.

8087 emulation on 8086 systems

Not too long ago I had a need and an opportunity to re-acquaint myself with the mechanism used for software emulation of the 8087 FPU on 8086/8088 machines. ↫ Michal Necasek Look, when a Michal Necasek article starts out like this, you know you're in for a learnin' ol' time. The 8087 was a floating-point coprocessor for the 8086 and 8088 processors, since back in those early days, processors did not include an integrated floating-point unit. It wouldn't be until the release of the 486DX, in 1989, that Intel would integrate an FPU inside the processor itself, negating the need for a separate chip and socket. Interestingly enough, Intel also released a cut-down version of the 486 with the FPU removed, the 486SX, for which an optional external FPU did exist.

How hard is it to open a file?

Sebastian Wick has a great explanation of why opening files - programmatically - is a lot more complex and fraught with dangers than you might think it is. This issue was relevant for Wick as he is one of the lead developers of Flatpak, for which a number of security issues have recently been discovered, and it just so happens that many of these issues dealt with this very topic. The biggest security issue found was a complete sandbox escape, originating from the fact that flatpak run, the command-line tool to start a Flatpak application, accepted path strings, since flatpak run is assumed to be run by a trusted user. The problem lay in a D-Bus service sandboxed applications could use to create subsandboxes, and this service was built around, you guessed it, flatpak run. The issues in question, including this complete sandbox escape, have been addressed and fixed, but they highlight exactly the dangers that can come from opening files. This subsandboxing approach in Flatpak is built on assumptions from fifteen years ago, and times have changed since then. If you're a programmer who deals with opening files, you might want to take a look at your own code to see if similar issues exist.
