I’m a technical kinda guy, doing technical kinda stuff.
Blu-Ray USB drive and M-Discs is about the best you can get at present. Keep the drive unplugged when not in use, it’ll probably last 10-20 years in storage.
Seeing as there hasn’t been much advance past Blu-ray, keep an eye out for something useful to replace it in the future, or at least get another drive when you notice them becoming scarce.
I don’t think there’s anything commercially available that can do it.
However, as an experiment, you could:
You could probably/eventually script this kind of operation if you have software that can automatically identify and group images.
Dammit now I have to reduce the block size of my discord-based cold storage filesystem.
They need to learn how to use their tools better. Winscp does all that transparently for you if you press F4 on a file on a remote system. Or maybe they did and you just didn’t see it…
It’s quite a handy function when you’re diving through endless layers of directories on a remote box looking for one config file amongst many.
If library devs do versioning correctly, and you pin to major versions like “1.*” instead of just the “anything goes” of “*”, this should not happen.
Your unit tests should catch regressions, if you have enough unit tests. And of course you do, because we’re all operating in the dream world of, “I am great and everyone else is shit”.
Letting it ring has no impact. They have autodiallers that call, and when someone picks up, only then is that call assigned to someone in the call centre.
You can often tell this because there is a marked delay in the response to your initial “Hello?”. Long enough that you can reliably just hang up if you don’t hear a response in two seconds.
If it’s a real person who actually wants to call you and they you call again straight away, you can just shrug off your hang-up as a network issue.
how the IT team tries to justify being locked into Microsoft, and then telling me I could potentially become a point of vulnerability
Because they can manage and control all the windows PCs , pushing updates automatically, restricting what users can do locally and on the network, they have monitoring tools and whatever antivirus and antimalware tools they have, and are able to easily manage and deploy/remove software and associated group licensing and so on and so forth.
Meanwhile you’re a single user of unknown (to them) capabilities that they now have to trust with the rest of their system, basically.
The first rule of corporate IT is, “control what’s on your network”. Your PC is their concern still, but they have no effective control over it. That’s why they’re being a bit of a pain in the ass about it.
True. Hence my caveat of “most cards”. If it’s got LEDs on the port, it’s quite likely to signal which speed it is at with those LEDs.
I haven’t yet come across a gigabit card that won’t do 10Mbit (edit: switches are a different matter) but sometimes I’ve come across cards that fail to negotiate speeds correctly, eg trying for gigabit when they only actually have a 4 wire connection that can support 100Mbit. Forcing the card to the “correct” speed makes them work.
I’m guessing something like:
Robots.txt: Do not index this particular area.
Main page: invisible link to particular area at top of page, with alt text of “don’t follow this, it’s just a bot trap” for screen readers and such.
Result: any access to said particular area equals insta-ban for that IP. Maybe just for 24 hours so nosy humans can get back to enjoying your site.
Energy efficiency can be offset by extra computational ability though.
Eg Linux has a plethora of CPU and IO schedulers and allows you to tune the system to maximise performance for your particular workload. Getting more performance than with the generic CPU and IO schedulers provided in other OS’s generally means more power consumption, unless you do some sort of “performance per watt” calculation to take that into account.
For later reference, the link light on most network cards is a different colour depending on link speed. Usually orange for 1G, green for 100M and off for 10M (with data light still blinking).
I have not cared about or terminated A-spec after network cards gained auto MDI/MDIX about 20 years ago.
Yeah , it’s really a little strange in OPs case, I can’t really recall changing a CMOS battery in ages, like decades of computer use.
Conclusion: just replace the CMOS battery on a yearly basis during planned system downtime.

It does? Wow this technology stuff is more insidious than I thought.
I have to wonder if there is a way for clients to glom together duplicate posts across your subscribed communities into one, and if you reply to a thread in that post it passes it back to the correct discussion.
I mean, you’d still see repetitive stuff in the post’s comments from your point of view, but everything would be in one place from your perspective and it would be semi-transparent, at least for the communities you subscribe to.
All the information is there, it should be doable…
Have a look here at the ICMP source code in the Linux kernel at line 400. That is the ICMP reply code.
At lines 433/434 you can see the collection of the source and destination MAC addresses from the incoming packet. The source is just lifted directly from the packet, the destination is done with a helper function that presumably looks at which interface it arrived on and returns the MAC address of that interface.
Lines 441 onwards construct the reply packet and push it to the generic ICMP transmit function (which is a bit higher up in the source code), which then pushes it on to the network stack.
Hope that gives you an idea of how it works internally! It’s really only a slightly more detailed version of the actual standard, there are a few checks to make sure that we are not exceeding network rate limits in the stack and etc, but it’s a quite simple bit of code.
Added edit: it’s “simple” at this point because a lot of the work has already been done. The packet has arrived via the network stack, it has been determined to be an ICMP packet, and it was sent here to this function. There are already functions that send packets out via the network stack, so this chunk of code just builds an appropriate packet and hands it on to be sent.
What you have linked to is a high level overview of what happens in an ICMP response, regardless of what OS or network stack you are using.
If you ask me to describe what Linux would do at that kind of level, well, exactly that.
Directly from the nginx home page:
nginx [engine x] is an HTTP and reverse proxy server, a mail proxy server, and a generic TCP/UDP proxy server, originally written by Igor Sysoev.
As another poster has mentioned, M-Discs are written using a Blu-ray writer and are good for a few hundred years, in theory.
