CNN: breathlessly reporting in 2022, stuff we all knew in 1991


Half the worlds population wasn’t alive in 1991.


CNN isn't really reporting to "the world", and the US (or Europe) has a considerably higher median age. Decision makers at high levels are even older.


MS-DOS user experience was extremely similar CP/M. In fact, one could safely say MS-DOS/PC-DOS only existed in the first place as a "quick and dirty" approximation of CP/M. (because IBM and Digital Research could not agree to licensing terms to bring CP/M to the IBM PC)

https://en.wikipedia.org/wiki/Digital_Research#CP/M-86_and_D...


So similar, in fact, that it led to years of allegations that MS-DOS was a ripoff of Digital Research's intellectual property (see https://en.wikipedia.org/wiki/86-DOS#Intellectual_property_d...).

> one could safely say MS-DOS/PC-DOS only existed in the first place as a "quick and dirty" approximation of CP/M

One could indeed, especially seeing how the original name of the product Microsoft acquired and turned into MS-DOS 1.0 was QDOS, which stood for "Quick and Dirty Operating System" (see https://en.wikipedia.org/wiki/86-DOS)

:-D


The story is weirder than not just agreeing to licensing terms. Gary Kildall (of Digital Research) and IBM have wildly conflicting versions of how their meeting went. To the point that I don't think the exact circumstances will ever be clear.


I've only ever heard of the IBM/MS side of the story. Where can we find Gary Kildall's version?


It's out of print now, but "Hard Drive" by James Wallace and Jim Erickson tells it: https://www.amazon.com/Hard-Drive-Making-Microsoft-Empire/dp...


The MS-DOS Program Segment Prefix[1] exists for source compatibility with CP/M.

https://en.wikipedia.org/wiki/Program_Segment_Prefix

https://en.wikipedia.org/wiki/Zero_page_(CP/M)


Also, first 9 or so functions of INT 21h were directly analogous to CP/M's BDOS. DOS also used FCB similar to CP/M.


This is true for MS-DOS 1.0, but 2.0 introduced tree-structured directories, which 8-bit CP/M didn't have.


2.0 was also the "breakout" version of MS-DOS that made it win over CP/M.

It did it by introducing features inspired by another Microsoft OS, the Unix for 8080 known as Xenix: - tree structured directories - pipes - output redirection - DEV directory (mostly hidden as it didn't catch on, afaik)


"For the Pro computer, that new case design helps the new Pro get “about 20 percent more airflow” compared to the Power Mac G5 that precedes it."

I lost any respect for the writer with that sentence.


"Please don't post shallow dismissals, especially of other people's work. A good critical comment teaches us something."

Perhaps they meant the G5 case design which the 2006-2012 Mac Pro shares?


You mean the comparison with cars didn’t do it for you?


You could call it "GeoCities"


Which is now replaced by NeoCities [1] It is open source, so you can run it yourself if you wish, or make use of their infrastructure.

Why expect any city to become another?


Agreed. There will only ever be one SF. And Nashville has it's own character I hope it maintains as it grows. But I also hope they're not so anti-growth that they choke off development. At any rate, nimbyism seems to be less prominent in the South, in my experience, so I bet they'll embrace the growth.


Key being the word "successful":

- learned things at their previous founding attempt/s

- serial entrepreneurs probably have their act together


Simple greed? As in: "play ball, and you get access to the gigantic Chinese market"


Suggest adding a [2009] tag to let people know from whence this wonderful paper dates.


Added. Thanks!
