That's a great find, but afaict that model doesn't have VNA capabilities, does it? However, if you also stumble on a spectrum analyzer at that second hand store, you could combine them into a scalar network analyzer.


Oops yeah you're right, it's a VNG. A VNA would be great to have though! I wonder if these agents are going to just increase the utility of ever piece of equipment people can hook them to.


This is great news if you're a mouse with diabetes.


As a mouse with diabetes sometimes you have to wonder how did I get here?


This doesn't even have sufficient controls to demonstrate that.

This title could have been called 'mice like to run more than they like to lift weights'


But do you know why mice is often used instead of says, cat?


> Voice encryption/scramble on Amateur-Band's is not allowed, everything else is ok.

It seems like you're saying voice encryption is not permitted, but data encryption is? This is not true in the US. Any encoding used for the purpose of "obscuring meaning" is not permitted on amateur frequencies. Even using code phrases like "the eagle has landed" is arguably not allowed. There are some narrow exceptions for things like satellite control codes, but nothing that applies to hobby mesh nets.

Here is the relevant Part 97 rule: https://www.ecfr.gov/current/title-47/part-97#p-97.113(a)(4)

> No amateur station shall transmit: [...] messages encoded for the purpose of obscuring their meaning, except as otherwise provided herein; obscene or indecent words or language; or false or deceptive messages, signals or identification.


So numbers stations fall under as otherwise provided?


No, numbers stations are not permitted on amateur frequencies in the US. There are some notable cases of foreign governments setting these up and interfering with amateur allocations [1], but there's not much the FCC can do about that.

It sounds like GPS, and thus a GPS-based stratum 1 server, uses these time servers, but they were successfully failed over:

> Jeff finished off the email mentioning the US GPS system failed over successfully to the WWV-Ft. Collins campus. So again, for almost everyone, there was zero issue, and the redundancy designed into the system worked like it's supposed to.

So failures in these systems are potentially correlated.

The author mentions another solution. Apparently he runs his own atomic clock. I didn’t know this was a thing an individual could do.

> But even with multiple time sources, some places need more. I have two Rubidium atomic clocks in my studio, including the one inside a fancy GPS Disciplined Oscillator (GPSDO). That's good for holdover. Even if someone were jamming my signal, or my GPS antenna broke, I could keep my time accurate to nanoseconds for a while, and milliseconds for months. That'd be good enough for me.


The CSACs that I have in a couple devices are 'atomic', and use Rubidium, but they're a bit lower accuracy than Cesium clocks [1] or Hydrogen Masers [2].

There are a few folks on the time-nuts mailing list who own such exotic pieces of hardware, but those are pretty far out of reach for most!

Atomic clocks cover a pretty big range of performance nowadays. You can pick up a used but serviceable rubidium frequency reference for a few hundred dollars but the difference between it and the top of the line clocks is almost as big as the difference between a it and a good pendulum clock.


On my iPhone, I can see the size of my iCloud photo backups. Settings -> Apple Account -> iCloud -> Storage.

Weirdly, that number is different than Immich’s estimate of my photo library (95 GB vs 150 GB), but perhaps good enough to get you in the ballpark.


Oh yes, of course. Thank you. 422 GB. Looks like my wife has slightly more.


I self host an Immich [1] instance to backup photos on my iPhone. It’s OSS and has a level of polish I’ve rarely seen in free software. Really, it’s shockingly good. The iOS app whisks my photo off to my home server several times per day.

What I’m not sure about is how to backup things like iMessages, Notes, and my Contacts. Every time I’ve looked, it appears the only options are random GitHub scripts that have reverse engineered the iMessage database.

1. https://immich.app/


The imessage db is literally just a sqlite db. If you have a Mac you can read the entire thing with an applescript. It’s really easy from what I remember from years ago


I run a nextcloud [1] instance and use it for contacts, calendars, and reminders

1. https://nextcloud.com


I use Nextcloud for files/contacts/calendar/etc. as well, but for photos I use PhotopPrism [1].

The reason is simple: photos require much more processing and focus on performance. In addition, photos take up much more space, so while my Nextcloud instance runs on an SSD, the photos reside on an HDD, mostly in sleep mode.

What's wrong with `imessage-exporter`?

https://github.com/ReagentX/imessage-exporter


There’s an infamous case of xerox photocopiers substituting in incorrect characters due to a poorly tuned compression algorithm. No AI necessary.

https://en.wikipedia.org/wiki/JBIG2#:~:text=Character%20subs...


Yeah, I had that case in mind actually. It's a perfect illustration of why compression artifacts should be obvious and not just realistic-looking hallucinations.


I don't understand why people downvote questions like this rather than just answer the question. It's a perfectly reasonable question imo given that it's not clear how this feature is being disabled. It appears that most of this is based on reddit speculation and the OEMs don't provide a definitive answer.

Meta: recently it seems like the community has been way too loose with the downvote button, but I'm not sure if I'm just noticing it more because it's getting on my nerves, or if there has actually been a change in behavior.


There has been a change in behavior in the past few years, in fact it used to be that you could only become a HN member that can comment thus vote by posting a select number of threads before being able to comment. This actually kept the community on the more intelligent, factual, and serious side. Now it's not so serious.

This used to be the only place that I could visit to get away from Reddit behavior. It seems like the more obscure a social gathering is, the less Eternal September it suffers.

The term "orange reddit" feels more and more like reality as time goes on.


Sure it's not

Why does anyone care about downvotes? Is there somewhere I can cash in my karma points here for something actually valuable?


From the article:

> This allows for some interesting new deployment models for DuckDB, for example, we could now put an encrypted DuckDB database file on a Content Delivery Network (CDN). A fleet of DuckDB instances could attach to this file read-only using the decryption key. This elegantly allows efficient distribution of private background data in a similar way like encrypted Parquet files, but of course with many more features like multi-table storage. When using DuckDB with encrypted storage, we can also simplify threat modeling when – for example – using DuckDB on cloud providers. While in the past access to DuckDB storage would have been enough to leak data, we can now relax paranoia regarding storage a little, especially since temporary files and WAL are also encrypted.


Seagate has a proprietary version of SMART called FARM. It’s supposed to be more tamper resistant than SMART, but it appears the fraudsters have figured out how to manipulate it too [1].

The best you can do is check FARM if available and perform a long burn-in with something like badblocks. Then compare the SMART data before and after the burn in. Checking the serial number against the manufacturers database if available is also a good precaution.

These are probably things you should be doing whether or not the drive is allegedly new.
