I always wanted to like DVD-RW and CD-RW. But I just couldn't.

Cost. A couple dollars per disc, versus a couple pennies per disc for the one-time use.

Easily scratched.

They were slow. You could use a Syquest or Iomega 1GB drive, boot off it, etc. Basically as fast as a hard drive was.

They were compatible until they weren't. Plenty of issues trying to read those things on other computers.

Why did the author have to do all this hacking around with screenshots? Back in the day, you could query any window for its title/text/buttons and send events to the buttons directly. Is this not the case in Windows any more?

Apart from win32 itself, most frameworks (everything from Java Swing to Electron) just use the win32 API to draw pixels to the screen and don't integrate with the window hierarchy.

Music-wise, lossy compression takes place via a proprietary codec (ATRAC). It isn't viable for data storage (neither was CDR(W)). Trust me, I had data loss due to all of these. Just use LTO with some parity data.

Not sure I understand, are you saying that you were using MiniDiscs or other MO media and were experiencing bit rot? Making ATRAC the exclusive and mandatory codec for MiniDisc Audio was another typical unfortunate Sony move but in my view doesn't discredit the strengths of the physical storage medium.

Honestly, I wasn't being specific. I like a specific music genre, and within this music genre some unique content was saved to DAT and Minidisc. The DATs were lost, and so the only available medium has been based on Minidisc.

I didn’t know there was a rewritable dvd format. My dad had a bunch of dvds, I used to love sneaking one off to play on my computer when I was a kid, since he stopped noticing when he got into bluray

DVD±RW was super useful for passing around files in a period where flash drives were expensive. My high school photo journalism club used them a lot to pass around photos and documents, a couple days later they'd get ingested into the PC in the club room, erased, and put back on the pile for you to bring one home.

I don't ever think I had one fail to write

I thought two-three times. Maybe a dozen. I always treated all kinds of writeable CD/DVDs as if they were one-write and done. To be honest, it hurts every time I write to an SSD drive — which is all of the time these days.

I just checked using $ sudo smartctl -a /dev/nvme0n1 Percentage Used: 2% Data Units Read: 7,173,143 [3.67 TB] Data Units Written: 22,666,414 [11.6 TB] That's after about 2 years of use. I think SSDs can take quite the beating nowadays.

Not bad ;)

One hint for the wary: Don't delay feature updates for the maximum allowed in the group policy editor. I couldn't figure out why I was getting forced reboots for updates despite other policies requiring it to ask permission. Turns out that if the update hits the group policy maximum, it forces an update immediately, other policies be damned. So set it to the max - 14 days if you want some time to apply updates at you…

You could also use an OS that doesn't tend to have dodgy updates that brick your system, such as most Linux distro. Nor force you to update if you don't want to. Funny how a large company like Microsoft can't figure out QA, but volunteer Linux distros with much less resources can. (A lot of Windows specific software works in wine these days, Valve's investment into improving it for games have helped for applications…

I haven't done it recently but back when I was learning Linux, I definitely bricked my fair share of installations updating and installing things.

It was probably fixable to a more experienced person but it wasn't to me.

Linux is a lot of things but brick-proof for novice users isn't one of them.

You write 3x more than you read? Seems like a strange access pattern. Maybe something is going haywire with logging?

>Windows Updates If you want to stop windows updates, make your internet connection a metered connection. Updates will only be allowed on-demand. The more you know!

For a nuclear option, delete C:\windows\system32\wua* or move these files somewhere else.

The nuclear option is linux

I never managed to get Fusion 360 running reasonably on Linux, in the end I switched CAD software. It really needs some sort of reasonable OpenGL support (or maybe DirectX, I forget which it was). And it doesn't work under wine, it did at some point but then it stopped. Cloud connected software, so you can't just run an old version.

Maybe if you had a second GPU and forwarded it to the VM? Not willing to spend that extra money, and it would only work on my desktop, not my laptop.
