“His specialty was alfalfa, and he made a good thing out of not growing any. The government paid him well for every bushel of alfalfa he did not grow. The more alfalfa he did not grow, the more money the government gave him, and he spent every penny he didn't earn on new land to increase the amount of alfalfa he did not produce. Major Major's father worked without rest at not growing alfalfa. On long winter evenings he remained indoors and did not mend harness, and he sprang out of bed at the crack of noon every day just to make certain that the chores would not be done. He invested in land wisely and soon was not growing more alfalfa than any other man in the county. Neighbours sought him out for advice on all subjects, for he had made much money and was therefore wise. “As ye sow, so shall ye reap,” he counselled one and all, and everyone said “Amen.”

We changed the way we track Go threads in syscalls/cgo calls, which allowed us to remove one atomic store and one atomic compare-and-swap from the cgo call path. https://go.dev/cl/646198 and https://go.dev/cl/708596 are the relevant changes.

(It's basically an easter egg, but if you look at the source of the release notes, you will see that most entries in the release notes have an HTML comment referencing the Go CL or issue that the entry refers to.)

How does this work when using a US credit card in the EU? I assume the merchant still pays the lower interchange fee, so are the banks just betting that customers won’t do a large proportion of spending abroad?

> 2. Cell service has, at the same time, become ubiquitous in subway tunnels.

Not in New York, unfortunately. All of the stations have cell service, and one tunnel (14th Street L train tunnel under the East River), but everywhere else has no service between stations. It’s an annoying limitation that most cities seem to have fixed by now.

I can’t quite tell if this is satire! You may be familiar with a small startup (https://en.m.wikipedia.org/wiki/Netflix) in the business of buying a million DVDs and continuously renting them out on demand to make something resembling a video rental store.

In addition to the DoS aspect mentioned in a sibling comment, the primary reason you would do this is to avoid constraining the implementation. If you want to change the design to improve performance, for example, being forced to match the implicit ordering of the old implementation may be very difficult.

It certainly may be useful to define an specific ordering. Maps ordered by insertion time and maps ordered by key order are fairly common. But maps with these constraints probably won't be as fast as those with arbitrary ordering, so there is a trade-off decision to be made. A map constrained to the arbitrary ordering of the initial implementation is the worst of both worlds: difficult to make faster despite not having a particularly useful ordering.

As a concrete example, I am currently in the middle of rewriting Go's map implementation to use a more efficient design (https://go.dev/issue/54766). If Go hadn't randomized map iteration order this work would likely be impossible. It is unlikely we could completely change the design while keeping iteration order identical to the old implementation (assuming we want the new version to be faster at least).

I think the closest analog to this is digital services getting worse rather than more expensive. For example, recently rather than increasing the price of Amazon Prime Video, the price has remained the same, but the product is worse (now has ads).

That said, I don’t think this bill would target something like that, as it clearly discusses the “size” and “amount” of a product.

Q1 earnings (https://s25.q4cdn.com/442043304/files/doc_financials/2023/q1...) says 383M daily active users and $1.3B in costs (including sales, administrative, etc), for ~$3.50/user/quarter or ~$14/user/year. So far above $2.50/user/year. Even just using cost of revenue is ~$4.50/user/year.

See https://news.ycombinator.com/item?id=34097179. A comm is limited to 64 bytes, so I don't think it is possible to fit a long enough comm to match the full regexp.

Neat! Your parser [1] almost has a similar issue because a comm could contain parenthesis, e.g., `foo) R 123 456`. But since a comm is limited to 64 bytes, I don't think it is possible to fit a fully matching string inside of the comm before the closing parent after the comm, which would thus make your regexp fail to match.

Gerrit is pretty strongly opinionated, but it is not mailing-list based. Review notifications are sent via email, but otherwise everything needs to be done via the web UI (or other tool using the API).

I’m not familiar with Upsource, but what you describe sounds somewhat like the Gerrit review process. Each commit is reviewed individually, but sending multiple dependent commits for review is supported as well. It is technically possible for a coworker to build on top of your unsubmitted changes (by checking out your commits and adding more on top). However this process gets somewhat painful if the coworker updates their commits, which would require you to do a convoluted rebase.

The benefits come primarily from avoiding extra work spilling arguments to/from the stack on function calls. If you are making lots and lots of function calls, particularly to small functions that can't be inlined, there could certainly be much bigger improvements.
