There's a lot of things like this, especially when the connector is commonly used for just one thing. One is "composite video" which at one point or another I have heard items on this list used interchangeably (though not always at the same time):

composite video - RS-170 - monochrome video - EIA-170 - NTSC - black and white video - CVBS - B&W video - RS-170A - analog video - PAL - yellow RCA plug - just plain "video"

These don't even all refer to the same thing, and some are definitely more correct than others, but all are used even by technical people.

Here's another one: "Amphenol connector", "Cannon connector" or "Molex connector". It's the same as saying "Ford car".

You forgot SMPTE 170M, which is probably the definitive standard at this point:

Most 8P8C other connectors are incompatible with RJ45.

Why wouldn't you say RJ45?

wsh · 5 months ago

RJ45S and RJ45M are ordering codes for so-called “registered jack” configurations for terminal connections to the U.S. telephone network. These codes were defined until 2000 in the FCC Rules (47 CFR § 68.502(e)) and later in the TIA/EIA-IS-968 standard, and they refer to single and multiple arrangements of two wires and a programming resistor on a miniature eight-position keyed jack.

https://www.govinfo.gov/content/pkg/CFR-2000-title47-vol3/pd...

Unfortunately, the “RJ45” part of these codes has become a metonym for the unkeyed version of the miniature eight-position jack and plug, now widely used for Ethernet and other purposes, but strictly speaking, RJ45 refers to a different connector with totally incompatible wiring.

Around 15:30 in this video she talks about it, and there’s a slide showing other symbols that may or may not be from the same book.

Interesting. The left side of the slide at 15:43 in the video is definitely from page 27 of Symbol Sourcebook, but the detail of the ⌘ symbol doesn’t seem to be: not only could I not find the symbol, but also its caption (“FEATURE”) is set in Helvetica rather than Univers as used in the book.

I don't know, and I'd love to.

If I had to guess, I'd guess Henry Dreyfuss's Symbol Sourcebook. It was published in 1972, and it seems plausibly the sort of book someone like Susan Kate might have had to hand in the early '80s. https://www.societyofsigns.com/projects/symbol-sourcebook

wsh · 5 months ago

Symbol Sourcebook would’ve been my first guess, too, but I just glanced through my copy (7th printing, 1977) and didn’t see the ⌘ symbol. The closest thing in the Graphic Form Section is a symbol for “Atomic d orbital,” but it’s clearly not the same one that inspired Susan Kare.

wsh commented on Ask HN: Any updates on what is happening to io domains? · Posted by u/WolfOliver

The treaty returning sovereignty over the Chagos Archipelago to Mauritius, disestablishing the British Indian Ocean Territory, seems to be on track for ratification:

https://commonslibrary.parliament.uk/research-briefings/cbp-...

The consequences for the .IO ccTLD are still unclear and ultimately will depend on how the United Nations, the ISO 3166 Maintenance Agency, and ICANN respond. I’m not aware of anything more definitive than ICANN’s blog posting from November 2024, which emphasizes that “much of the discussion about .io is simply speculation” but also acknowledges the possibility that “a five-year time window will commence during which time usage of the domain will need to be phased out.”

https://www.icann.org/en/blogs/details/the-chagos-archipelag...

I wouldn’t use a .IO domain name for anything important.

wsh commented on The Case for Centralizing Authorization aserto.com/blog/the-case-... · Posted by u/mooreds

Animats · 9 months ago

No mention of Kerberos? That's been doing centralized authorization for decades. It's built into Windows, even.

wsh · 9 months ago

I’ve always thought of Kerberos as a centralized authentication system, to establish users’ identities.

Authorization, in the sense of deciding to allow or deny a requested action by a known user on a specific object, remains distributed, even with Kerberos. For example, a Windows file server, having received a Kerberos ticket showing a user’s identity and security group memberships, consults its own access control lists to determine what operations to allow on files and directories.

The article here argues that those authorization decisions should also be centralized, presumably using the sponsor’s “cloud-native authorization platform,” instead of being made within each service or application.

Those links are dead.

Correct link to "Rodent-proof vinyl adhesive tape No. 347":

Both links worked earlier, but they don’t work for me now, either.

Anyway, the data sheet explains how the manufacturer tested the tape’s effectiveness with rats. The Wayback Machine has a copy:

If rmm, hsm, and dfp mean something, and IBM's documentation didn't explain the names to me. they are some of the most extraordinary acronyms, _mixed-case_ no less, I've ever seen.

wsh commented on Ask HN: Who do I contract to write a EULA? · Posted by u/avowud

brudgers · a year ago

Your lawyer is the best place to start. If you don’t have a lawyer, there’s not much you can do to enforce a EULA and therefore not much point in making one. Good luck.

wsh · a year ago

I agree with the advice to ask a lawyer, but it’s sensible to be concerned with license agreements even in early-stage ventures that couldn’t enforce them.

By establishing the company as licensor, an agreement might help the founders avoid personal liability if a customer sues. Later on, it may be desirable to show potential acquirers that, from the company’s inception, its customer contracts included terms to confirm ownership of intellectual property, limit liability, satisfy privacy laws, and so on.
