If you’re wondering, as I was, who Amateur Radio Digital Communications is and how they have money to make grants, it’s the foundation that sold a quarter of the 44.0.0.0/8 IPv4 address block, allocated in 1981 for use in amateur radio, to Amazon in 2019 for $109 million.

FS.COM Limited (深圳市飞速创新技术股份有限公司, https://cn.fs.com/) was founded in Shenzhen in 2009. They’ve applied to be listed on the Hong Kong Stock Exchange; here’s the draft prospectus from a month ago:

I liked An Answer for Linda (1961), which shows the work of outward toll operators using mark-sensing call tickets at traditional (3CL) cord switchboards. “Watch Billie closely, as she handles a group of typical calls.”

(I won’t spoil the Answer; you’ll have to watch for yourself.)

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

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.

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.

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.

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.

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.

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:

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.

Yes. “Freight collect” means the recipient pays the carrier for transportation; it implies nothing about payment for the goods.

“COD” (collect on delivery) means the carrier collects a specified amount of money—typically, the price of the goods plus transportation—from the recipient, on behalf of the seller, as a condition of delivery.

I have the now-discontinued Sony DPT-RP1, which I use with Jan-Gerd Tenberge’s software (https://github.com/janten/dpt-rp1-py). It works well for reading PDF documents without the need for frequent zooming or scaling.

If I had to replace it today, I’d buy a Fujitsu Quaderno A4 (FMVDP41), which I understand has a design very similar to that of the Sony product.

> It is not legal to operate a remote transmitter site without [...]

47 CFR § 73.1400(b) permits operation with “a self-monitoring or ATS-monitored and controlled transmission system that, in lieu of contacting a person designated by the licensee, automatically takes the station off the air within three hours of any technical malfunction which is capable of causing interference” (emphasis added).

This doesn’t change the licensee’s basic responsibility “for assuring that at all times the station operates [...] in accordance with the terms of the station authorization,” of course.

> in what ways were they operating noncompliantly?

If the station was off the air and the licensee didn’t notify the FCC within 10 days and seek a silent STA within 30 days, that would violate 47 CFR § 73.1740(a)(4).

The website claims “Design, Construction and Operation according to US SUBSAFE.” I’d want that for my submarine, of course, but I wonder if it’s realistic.

I’d understood that SUBSAFE was a comprehensive program applied to U.S. Navy submarines by the Naval Sea Systems Command, not merely a published standard with which one could comply without extensive, ongoing involvement by NAVSEA, which presumably has no mandate to support foreign yacht builders.

The author writes, about his purchases of computers, phones, and other hardware, “These are not recurring so I can't count them in.”

Here in the U.S., many such items would be considered capital assets, for which the cost would be recognized as an expense over time through depreciation, for both management accounting and tax purposes. It appears Romanian practice is similar; see “Depreciation” on this page:

Those are the new Inside Macintosh series, published starting in 1992. SpInside Macintosh, the HyperCard stack from which the web page linked in this item was created, was produced from the first five volumes of the original Inside Macintosh series, published from 1985 to 1991.

As the Preface to Inside Macintosh: Overview (1992) explains:

  The original Inside Macintosh library of books appeared in six volumes from
  1985 to 1991. Those volumes each focused on a particular version of the
  system software, sometimes prompted by the release of new hardware
  configurations. Often, the later volumes of the original Inside Macintosh
  described only new system software components or changes to existing
  system software components.

  The new Inside Macintosh books are intended to replace the original Inside
  Macintosh books and to provide a more complete and more useful reference to
  the Macintosh system software. The most obvious improvement in the new
  books is that they are organized principally by topic. For example, the book
  Inside Macintosh: Files contains virtually all the available information related to
  files, including complete descriptions of the File Manager, the Standard File
  Package, the Alias Manager, and the Disk Initialization Manager. Similarly,
  the book Inside Macintosh: Text contains all information about handling text.
  This topic-oriented organization of books makes it easier for you to find the
  information you need. It also makes it easier for Apple to add books to the
  Inside Macintosh suite as new technologies emerge in the years ahead.
If only they’d kept that up...

If customers know what they’re buying, and unsubscribing is convenient, then I see no ethical problem with selling limited-term licenses—but as you mentioned, some potential customers might choose not to buy.

Depending on the purpose of the software, it might be reasonable to require a current subscription only to enter new data or to perform new calculations, while allowing customers to view and export their existing data in perpetuity.
