Quorten Blog 1

First blog for all Quorten's blog-like writings

Sometimes I use Git over HTTPS on a private intranet, and there will be times where the Git client complains about a self-signed certificate. However, when running Git commands, this is fairly easy to fix, just export this environment variable as follows:

export GIT_SSL_NO_VERIFY=true

Really interesting resources on book scanning. It also covers some 3D scanning techniques as how they relate to 3D scanning.

Ha, that’s a really interesting way to put things. Build a high speed book scanner from trash.

Failed search. Where was it written that the first order of business was to play with the phone system? Business users might be unappalled to find this out. I thought it was on apple2history.org, but my search engine and my limited patience with a disfunctional search engine.

Got it! But I must admit, those modern web search engines sure are defective and make easy things almost impossible to find.

24-Renaissance?

Oh yeah, and to reiterate this particular conclusion, discovery. I don’t think I already wrote it down, though. Why was the Apple IIe finally retured in 1993? Because Apple’s second 8-year license to Microsoft BASIC expired, and Apple was not interested in renewing it. Why not? Well, if you were to ask me, I would say that it was because there already was a large market of BASIC runtimes available at the time, some of which worked for their Macintosh computer. And we know for sure that Apple wanted to push their Macintosh computer as the future of their company.

Stolen from Apple! The second web site contains the instructions to access the “Stolen from Apple!” icon on the Macintosh SE.

A site full of many other Apple Computer-product Easter Eggs.

Can you bootstrap the original Macintosh from bare metal? Nope, it can’t be done. Early generation Macintoshes must have boot disks to be functional. If they do not have a boot disk, they will fail to boot. You need at least a Macintosh Classic to be able to boot from ROM.

You know those descriptions of computers on Wikipedia? Yeah, at face value, they make things sound easier than they really are. Like, how do you boot a Macintosh computer? You need a boot disk. Without one, you can’t do anything useful with a Macintosh computer. Alas, the Macintosh was designed to work with significantly larger amounts of data than the microcomputers that came before it such as the Apple II, so it makes sense that you would need to insert a disk into the computer before it is usable.

Non-technical people? How do non-technical people use computers? Oh, here is their thought process. They will do the least amount of effort possible to see some cool picture or video, or they may spend all their time on social networking software. They will NOT make any more attempts to try to get things to work any better on a technical level. Yeah, I know, it sounds stupid, but that’s the way they are.

But, guess what the most interesting aspect about this behavior is? They actually don’t like their nature of this. They want to be better. They see spending too much time watching TV as a bad habit.

If you were wondering why the patents over video compression codecs are so political, it is due to the belief that there is a huge amount of money to be tapped from the relevant sector.

Is USB VGA a hoax?

USB VGA sounds kind of like a hoax. Is it? To some extent, yes it is.

The current solutions rely on video compression algorithms. And, as you know with any data compression algorithm, there is always the possibility of a worse-case that cannot be compressed at all. What happens when a video signal relies on a channel that cannot send enough video bandwidth except when the signal is compressed? What happens when an uncompressed signal must travel to the destination in time? Nothing, because it can’t reach its destination in time.

Interesting link, just saving it here for reference.

Be careful! Make sure you don’t confuse the Unidisk 5.25” Drive with the Apple 5.25” Drive. I have the Apple 5.25” Drive.

And no, you can’t use your Apple 5.25” Drive to read IBM 5.25” floppy disks. The capacity of IBM 5.25” floppy disks is too high.

Oh yeah! Add to Tour de Force. On reading the documentation of GNU Screen. Auto-margin terminals. This answers all your questions that you had about how terminals would behave when you type to the edge of the screen. Does it automatically wrap to the next line, does the additional text get truncated, or does the additional text overwrite the last character in place? This is the more technical terminology for this behavior. “Magic” margins allow you to type the last column on your screen before wrapping to the next line.

This terminology comes from Terminfo.
