yau8edq12i··on Digital Telecommunication in HF band - WWWAN - World-Wide Wireless Area Network
> we have and had absolutely no issues generating waves with 100s of THz frequency

In a way suitable for even medium range RF communication? No. That's what I mean. The required power would be insanely high. So high that it's not achievable without some breakthrough. I didn't literally mean "break the laws of physics", because that's something we obviously cannot do.

yau8edq12i··on Digital Telecommunication in HF band - WWWAN - World-Wide Wireless Area Network
Millimeter wavelength RF was already studied in the 19th century... The RF communication band you're talking about is smack dab in a band already defined in the original 1937 document.

Honestly the naming scheme makes sense to me. The spectrum is divided into 12 bands of equal (log) size, up to a frequency where we don't know whether such waves will ever be reliably generated at room temperature without breaking the laws of physics. Then these bands are consistently named from "extremely low" to "extremely high", with an extra annoying band at the top. Really, it could be worse.

yau8edq12i··on Digital Telecommunication in HF band - WWWAN - World-Wide Wireless Area Network
Ancient? The HF band is still very much in use... Modern developments have not changed the fundamental properties of RF propagation. UHF ("a few GHz") can only be propagated in line of sight reliably. HF can literally travel around the world.

Okay? Not really what we're talking about though. https://www.npr.org/2021/09/19/1038746061/submarine-deal-us-...

Of course, Australia found out they got the raw end of the deal a couple of years later: https://www.theguardian.com/world/2023/jun/15/australia-may-...

The Australian submarine deal suggests so, yes.
yau8edq12i··on Judge mulls sanctions over Google's destruction of internal chats
That only works in dreamland. Banks and traders must record all calls by law, for example. https://www.bankingdive.com/news/sec-cftc-fine-11-banks-18b-...

> The Securities and Exchange Commission (SEC) and Commodity Futures Trading Commission (CFTC) fined 11 Wall Street banks and brokerages more than $1.8 billion in a long-anticipated move to curb finance employees’ use of unapproved messaging platforms and companies’ failures to keep accurate records of those communications, the regulators said Tuesday.

But it's not a "cool" tech company so you don't hear about it on HN.

yau8edq12i··on Judge mulls sanctions over Google's destruction of internal chats
How is technical nature of your communication with others at all relevant? The court can order you to hand over the encryption keys, and if you destroy them, then it's the same thing as destroying the communication.
yau8edq12i··on Judge mulls sanctions over Google's destruction of internal chats
And before someone pops in with "but what if they deleted the key?" - well, then for all intents and purposes, they've also deleted the document, in violation of the legal hold.

How on Earth did you arrive at the conclusion "probably real" from that link?

I'm sorry but this anecdote sets off my BS detector very hard.
yau8edq12i··on Search.chatgpt.com domain and SSL cert have been created
If we want to be pedantic, X.509 mainly defines the binary format of these certificates.
yau8edq12i··on Search.chatgpt.com domain and SSL cert have been created
There is no such thing as an "SSL certificate" or "TLS certificate". There are certificates, which are used in various protocols including SSL and TLS. You can use the same certificate for both. The name "SSL certificate" is just a shorthand indicating the intended purpose of the certificate, nothing more. As such there really is no point in being pedantic over SSL vs TLS.
yau8edq12i··on RISC-V support in Android just got a big setback
It's really not that bad when you consider that RISC-V is built to be used in anything from a tiny mcu to a large server cpu. Compare with the set of extensions to x64, too.

yau8edq12i··on You can't just assume UTF-8
I don't know about Java, but the C# standard library is exceptionally well design with respect to variable byte encoding. https://learn.microsoft.com/en-us/dotnet/standard/base-types...

The built-in string.length method is useless (it returns the number of char objects) and I agree that's a problem, but the solution is also built into the language, unlike in JS.

yau8edq12i··on "So that a truncated partial download doesn't end up executing half a script"
Because if looking at the script you've downloaded for obvious errors or issues is not 100% effective, then it's only theater. Is that what you're saying?
yau8edq12i··on "So that a truncated partial download doesn't end up executing half a script"
Distributors usually give you a way to verify that what you've downloaded is correct, usually through checksums, PGP signatures, code signing... You forego that if you pipe the script to your shell. What if you make a typo and somehow pipe an HTML document to your shell? If you're unlucky this could wreak havoc.
yau8edq12i··on "So that a truncated partial download doesn't end up executing half a script"
Don't pipe curl/wget a script to a shell without reading what you've downloaded. This should be common sense. Do `wget $url; most install.sh` and only if you're satisfied with what you read, execute `sh install.sh`.

> This gets mentioned here everytime an article about LoRA is posted.

I wonder why!

yau8edq12i··on LoRA+: Efficient Low Rank Adaptation of Large Models
The acronym LoRA used in the context of deep learning (2021) is about seven years younger than the radio communication protocol called LoRa (2014). Type "lora" in a search engine and see what you get.

> However, once the site owner decided to use Adsense then in order to use this service the site needed to change according to Google's requirements.

Or realize what using the service means for the website, and backpedal on the decision to use adsense.

"Sketchy tld"? Even google's parent company uses it for its corporate website.
yau8edq12i··on Visualizing malicious IP addresses
Introducing obscurity to the process doesn't make it insecure. Criticism of "security through obscurity" is that security shouldn't rely on obscurity. The system should remain secure even if the attacker knows every detail of your system. Here the point of the "obscurity" (if you can call it that) is to avoid blowing up your logs and wasting compute cycles and energy on attempts that will fail anyway.

No, it's not even related to gate length or any kind of physical feature anymore. It's a purely marketing term. A "3 nm" node has a gate length around 16-18 nm.
