Not to say it's still not worth it. It could be. But the larger the org, the greater the inertia, and the longer you live with both ecosystems.

Microsoft has done a pretty thorough job of locking companies in like this, particularly through authentication and authorization systems (Active Directory) and the locked-down IT management infrastructure around them.

Ask Slashdot: What are the Costs of Switching Between Windows, MacOS, and Chrome? 66

UI changes, lost productivity, untransferrable knowledge... Long-time Slashdot reader theodp notes the folly of switching to an unfamiliar new environment to be "more productive"... Champions of the switch often insist workers will be able to hit the ground running and get the same or even more work done from the get-go in the new unfamiliar environment because it's 'more productive', a conclusion often shaped by conventional wisdom or their 'gut' feeling. Decision makers may also mistake their own 'light-user experience' for universal experience and believe all platforms are fungible.

And while it's one thing for a business to delay their delivery dates and increase costs of by introducing a switch in computing environments that's of unquantified and possibly dubious value, how about when a switch in computing environments is made that affects schoolchildren's ability to learn for a period of time?

While a MacBook Neo is indeed cute, what might be the possible consequences of a decision to move 25,000 students off Windows and onto MacBook Neos...? Or even the impact on a single kid who moves from a MacBook school to a Windows or Chrome school (or whose home computing environment isn't aligned with their school). Or students whose teachers decide learning in their classrooms should now additionally require an understanding of the Minecraft computing platform/UI (used in over 40,000 school systems.). Learning Management Systems and now various AI Edtech tools used by schoolkids are also subject to change.

"Even if students and schools eventually benefit from a new platform, one wonders how much learning is lost during the switch," theodp asks, "and what the financial and educational ROI and payback period look like." Are there bigger problems than we realize? Share your own thoughts and experiences in the comments.

What a coincidence, the ideas of Stalin and Mao are not just popular, but being implemented by the DNC!

What ideas are those? Are you familiar with the policies of Stalin and Mao in any way, or are you just parroting something somebody else told you?

Or use streaming. One-to-one from the studio to Netflix. The studio gives Netflix the app with trivial authentication. Cheaper and easier than sending drives through the mail.

VFX studios are already doing this for their production pipelines. The processing happens in a data center; all the artists see is essentially a terminal window. Nobody can "walk off" with anything.

I regret to inform you that you have woefully underestimated it. The actual retail rate offered to consumers is closer to $2200 US per gallon. Sources: internet-ink.com, cbc.ca. This $14 million fine is only worth like, seven thousand gallons, or less than 200 oil barrels of ink.

Comment Agents are good at finding bugs, not writing code (Score 1) 33

I've had no success getting Agents to help write code for SQLite. All the code I've asked Claude to write for me is slop that didn't work or worked poorly and never got committed. On the flip side, I do ask Claude to review the code that I write prior to committing, and it is good at that, often finding serious oversights that I had missed.

This observation, that agents are good at code review but bad at writing original code, seems to carry through into AI-generated bug reports coming into SQLite from third parties. The bug reports are generally good, but the suggested fixes not so much.

One report from about a month ago illustrates this. The median() aggregate function in SQLite is implemented by collecting the input values into an array of doubles, using quicksort to put them in order, and return the one in the middle. The bug report showed a carefully devised sequence of 1 million inputs that caused pathological O(N*N) behavior in the quicksort algorithm, which caused recursion to go too deep and blow out the CPU stack. The AI's suggested fix: Add a depth parameter to the quicksort algorithm and fail over to a slower sorting algorithm if the recursion goes too deep. The correct solution (originally recognized in the 1975 by Robert Sedgewick, but unknown to me before this issue arose) was to only call quicksort recursively on the smaller of the two partitions, and sort the larger partition using a loop (tail recursion). If recursion only occurs on a partition that is half the size of the original or smaller, recursion depth is limited to LogN. That turned out to be trivial to implement, and is faster and uses less code than the AI-suggested approach. Furthermore, after seeing Sedgewick's tail recursion idea, Dan Kennedy recognized that we don't actually need to sort both partitions at each step of the algorithm, but only the partition that contains the median. Dan's observation more than doubled performance. Hence by ignoring the AI's suggested fix, we more than doubled the performance of the median() function in SQLite.

Before you ask: The median() function did originally use the standard library qsort(), but I changed that into a hand-coded quicksort some time ago because the hand-written variant did not require a callback for each comparison, and was thus way faster.
