And what is wrong with:
BOOT/R5:E0000000 DUA0
$ BACKUP/IMAGE DUA0: MUA0:BACKUP.BCK/SAVE/INIT/LABEL=BACKUP
?

apart from:
1. The tapes only hold 90-ish MB so you'll probably need more than one. (could be worse, could be RX50 floppy discs)
2. You try buying TK50's in quantity now
3. If you're still using VMS, you're probably only doing this because you're an old git and showing off, as it's faster to emulate the thing on SimH, and you could just copy the disk image file somewhere else in a few seconds instead of waiting several hours for old serpentine tape technology to wind it's way from end to end 22 times.
4. You could (and probably should) think of several million things that you should be doing instead

You can still replace your battery? Samsung will be sure to relieve you of the horror of that tedious chore so you can support their market model properly.

While the A10 I have is nice, and I usually manage to break phones in a total bonehead maneuvre before the battery dies the death, I still feel somewhat agrieved that if I somehow manage to care for this device well enough for long enough, it's lifetime is still going to be finite.

And back on topic, I had an alcatel phone, until they updated the calculator app or all things to contain ads. I'm not sure what bit of the sea that landed in. I had hoped Samsung were above that sort of thing.

In the UK, there are four dominant carriers, O2, Vodaphone, EE and 3. All of the other carriers piggyback on those four to some extent, for example Tesco Mobile uses O2 as a carrier.

I have a number of SIM cards from sip2sim.uk which connect a mobile device to a VoIP service, which can be provided by their parent company, or any other VoIP provider on the planet. The SIM card itself does not provide a mobile telephone number, as the VoIP service does that. The mobile phone then becomes a registered device on that VoIP server, and consequently could be an internal extension on a corporate network, or any other kind of service provisioned via VoIP. The sip2sim servers just need, for each card, a server, username, and password. What happens to traffic after that point is down to the server you are logging in to.

These SIMs by default piggyback on UK O2, however in the event of no O2 signal, can switch automatically onto Dutch Vodaphone. Why Dutch? UK Vodaphone customers cannot roam onto EE's network, however Vodaphone customers from other countries can, so I effectively get three-network domestic roaming. Quite what will happen after Brexit, I have no idea.

My VoIP service is provided elsewhere, and I have all of my SIMs logging in to that, which means all of my devices have the same telephone number. This seems to confuse some organisations, but the practical upshot is that if you phone my number, you get me. I actually have multiple numbers, some of which I give to work contacts, others to private contacts, others to potentially spammy outfits, as numbers are cheap (as little as GBP 0.10) and can be terminated easily if a specific company starts to annoy me more than most. (British gas, I'm looking at you...)

One downside is that I have a UK telephone number which does not start 07. Numbers starting 07 in the UK are usally mobile telephone numbers, and despite many mobile networks actually offering non 07 numbers, quite a lot of companies think they are doing you a favour by refusing to accept 'mobile' numbers that do not start 07. The conversation usually goes:
Can I have your mobile number?
Sure, it's 014....
No, your mobile number
Yes. 0, 1, ..
No, it starts 07
No it doesnt
Yes it does
Stop asking me for my mobile number and then telling me that it's wrong!
(The conversation usually ends badly at this stage, although sometimes I actually get someone order a SIM card. Just don't get me started on the reaction I get from Carphone Warehouse staff when I try and buy a new mobile handset and they ask what network I'm with. (I just lie, it's easier))

So, I could allocate an 07 number to it, I do have an allocation, but why would I do that as it is still expensive to call 07 numbers from quite a lot of phone contracts when calls to landlines are practically free. (Ok, it's not a landline either, which just illustrates how easily confused the telecoms companies are)

Anyone worth half a karma point here will recognise 16384 as a power of two.

In my years of software development, numbers like this jump out at you, usually while debugging something that has crashed due to overwriting something, and suspicious powers of two just scream 'BUG' at me.

Perhaps this move to manufacturing has simply been caused by microsoft not allocating enough bits in the build number, and one more recompile has tripped the manufacturing release...

struct BuildNumber
{
    int IncrementalVersion : 14;
    int ReleaseToManufacturing : 1;
    int FinallyBugFree : 1;
}

(and if this really is the source code, we'll have to wait until release 32768 for a bug free version, assuming we don't hit -32768 first)
