Telco systems validate and may transcode voice data between phones, so the functionality is limited.

You can generate the coin movement operation in the air gapped machine, write it down on paper, and then use a normal, connected computer to transmit it to the network. The private key never left the air gapped machine, with this method.

The method I’ve read about is to print “the request” onto a QR code, have the air-gapped machine scan it, sign it and print off the signed transaction QR to be scanned into the networked computer to propagate to the network.

A bit more to trust but a lot less to type.

And then you get hacked anyway because the QR code generator was compromised and switched around a few bytes before creating the QR code.

Ideally it’s a functionality of the wallet, but I think only bitcoin armory has this function.

It can probably be a bit simplified by using IPv6, as that avoids the IPv4 checksum.

No, the checksum just moves to UDP; in the current system, the UDP checksum is set to 0. This is not allowed in UDP/IPv6, where the checksum, calculated over both the IPv6 pseudo-header and the UDP payload, must usually be set.

They still have to compute the Ethernet frame check sequence.

What are those tedious reasons? Like when booting on very old hardware, you got a Vista-like splash screen on Win7?

Some part of the boot stack expected to be able to make VBE calls to set the inital screen mode before loading actual drivers, which means hardware that wants to support Windows 7 needs to provide a CSM layer to support that even if it's otherwise booting via EFI (the CSM layer just rewrites VBE calls into EFI GOP calls, so the graphics card doesn't need to provide VBE itself)

It still does, it's now called "Secure Folder". There's "Insular" from F-Droid as well.

Does anyone else have any experience with this app?

Hi, I do the BD M-Dics at home, with Linux, with 0 problems. What problems did you get?

I do backups of my home servers to BD-RE discs (BDXL 100GB) once a week from ZFS storage. The only problem is poor drive quality - for past five years I changed two dives (Asus branded, all different models). Seems they are not made for regular writes. So, the weak point is not the media itself but availability of dives which may just be missing in 20 years perspective.

Same here with Yakuake. It's always there

I keep getting calls from recruiters offering 30k€ in North Spain, but they are hurting, as nowadays everybody is getting better deals thanks to remote work.

so I guess this is annual, not monthly? Or is there some other division of salary that I haven't thought of?

Yes, this is annual.

>switching ISPs may throw your internal network addressing in disarray which can be either a pain or a massive problem

Those are what ULA's do. A local router that provides global addresses and ULAs solves all your problems, and that's the default behaviour of OpenWRT (and probably other routers). If you want traffic to not leave your local network, listen to your ULA (fd00::whatever) and call it a day.

Can you tell us what the driver actually did? How did it "prevent" piracy, and what are your feelings about the allegedly bad software quality?

The driver was pretty simple. When a CD was inserted, it checked for a watermark and if there, returned pseudo random sectors of data. To play the CD on PC required using their software player. The software player had the ability to rip the CD to .wma files and this was how you were supposed to use the CDs. This only affected playback on PCs. CD audio players played the discs as normal CDs.

I never thought it would prevent piracy. They said it was a success even if only a small percentage are stopped by it. I didn't believe in the software but I do believe in copyright so I took the job. The software was put together by 4 guys on a shoestring budget. It's amazing it worked at all. People read into this and think big Sony/BMG money but in reality it's tiny contractors. Some of us were doxxed back then and was a pretty horrible experience all around.

There's a general trend for people to treat the happenstance actions of individual workers as fully-intentioned top-down decisions of a unified, hivemind multi-billion dollar entity. A previous employer of mine has been in the news for things where a shortcut by a single lazy engineer was interpreted as a political attack on free software.

Thanks for responding, it's quite interesting story.

So, if the driver was not running in the machine, the disc would be a standard Data+AudioCD? Nothing else to stop reading it as a generic music disc?

Autoplay. One of the single most stupid default settings in Windows ever since Windows supported removable media, which is a while ago. It's up there with the default of hiding full file names from you.

Basically, if you inserted the disc, Windows would see the data partition, and "helpfully" run the installer for you. Then you'd have the driver installed, and it would block access to read the disc as a generic music disc.

It was also a massive usability boost. The process of "insert installation CD" then "nothing happens" was a bad experience for an extreme segment of the user base.

In 1995 the idea of commercial products being adversarial is low. For the very few cases of the driver they install being unwanted, there's countlessly more cases of it being wanted.

This wasn't "secure by design," it was "usable by design." And for 99.9% of the people, it was likely both.

Yep that's right. It relied on autorun to install the driver when the CD was inserted. If that was disabled and the driver never installed then it was just normal 'bluebook' CD.
