The proliferation of the Internet of Things ( IoT ) has led to an explosion in the number of connected devices, from smart thermostats in homes to sensors in manufacturing plants. As these devices multiply, so does the complexity of managing them. Enter IoT device management — the suite of tools and practices designed to monitor, maintain, and update these interconnected devices.

If you wanted to cache a file ‘forever’, you’d probably use a Cache-Control header like this: Cache-Control: max-age=31536000 This instructs any cache that it may store and reuse a response for one year (60 seconds × 60 minutes × 24 hours × 365 days = 31,536,000 seconds ). But why one year? Why not 10 years? Why not max-age=forever ? Why not max-age=∞ ?!

While I am heartened to hear that the Executive Order on AI uses the Defense Production Act to compel disclosure of various data from the development of large AI models, these disclosures do not go far enough.

But before discussing why, it’s important to think about what prompt engineering means.

Memory is a relatively scarce resource on many consumer computers, so a feature to limit how much memory a process uses seems like a good idea, and Microsoft did indeed implement such a feature. However: They didn’t document this (!) Their implementation doesn’t actually save memory The implementation can have a prohibitively high CPU cost This feature works by limiting the working set of a process – the amount of memory mapped into the address-space of the process – to 32 MiB.
