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.
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”.
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.
There was a series of books in the '80s where a systems programmer gets pulled through a portal into your typical magical world, good vs evil, etc.
They subsequently look at the magical spells in use and realise they can apply Good Systems Programming Practices™ to it. And thus, with their knowledge of subroutines and parallel processing, they amplify their tiny innate magical abilities up to become a Pretty Good Magician™. So while all the rest of the magicians basically have to construct their spells to execute in a linear fashion, they’re making magical subroutines and utility functions and spawning recursive spells without halting checks and generally causing havoc.
It’s quite a good allegory for modern times, where a select few build all the magic and the rest just have useful artefacts they use on a day to day basis with no idea how they work
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.
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.
Let me know if I can explain it more clearly.
Multi-part MIME containing inline images is actually what you’re looking for and it’s fairly easy to implement.
Here’s an example. They handwave over the html section that actually refers to the inline images that they embed, but that’s the basic layout you need.
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.
What if I want to buy a cheese sandwich today with BTC?
A cheese sandwich can remain the same fixed price in dollars for years, with only the relatively slow change in actual value due to inflation.
I’ve seen BTC swing 10% in 24 hours. Does the cheese-sandwich-maker have to look up the rate this instant and calculate a spot price for me?
Will they have more or less dollars at the end of the day, when they need to pay their bills and buy more cheese from their suppliers?
“Just buy cheese from someone who takes BTC”, doesn’t help, it just kicks the can further down the road.
“Just add a bit of a buffer in the price to take fluctuations into account”, means that I go buy a cheese sandwich with dollars from next door because it’s 50 cents cheaper for the same thing.
As an investment vehicle, BTC is doing hot laps of the track (with occasional accidents), but until its volatility issues are sorted and it becomes “boring”, it’s not going anywhere as an actual currency.
To be honest, I was surprised it had any idea about FFMPEG. The biggest problem is that it sounds so authoritative.
If it said, “hey I don’t know a huge amount about X” then you could work with that. But it will blithely say “no problem” and spit out 6 pages of non working code that you then have to debug further, and if you don’t know the terms in the area you’re working in you end up blundering around trying to find the right trigger word to get what you want.
I end up having to play twenty questions with chatgpt. For example, I’ve been asking it for code examples for ffmpeg mpeg4 encoding with C++.
It will happily spit out completely non-working code, where the core part - feeding image frames to the encoder - works, but it doesn’t initialise or tidy up the encoding afterwards.
Until I say, “hey this code doesn’t seem to work and creates corrupted files”, and then it’s like, “oh yeah you also need to do a bunch of other stuff, just like this”. Repeat as it slowly adds more and more pieces until finally you end up with something that actually works.
Or it will happily dream up function names or mix python and C functions, or will refer to older APIs even when I’ve specifically said “use API version x.y” and so on and so forth.
If I didn’t know enough about the subject already, I’d never be able to tease out the answer. So in a sense it’s a mostly useful reference, but it can’t be relied on to actually and consistently provide a result because it’s all statistics and fuzzy text generation behind the scenes, not actual knowledge.
As another poster has mentioned, M-Discs are written using a Blu-ray writer and are good for a few hundred years, in theory.
