Was CP/M overrated?

Was CP/M overrated?

Veteran tech journalist Dan Tynan recently published a list of 10 overrated technology products, and CP/M was on his list. But was CP/M overrated? I want to dig into that question a bit.

I think everyone knows the story of how IBM almost used CP/M as the operating system for its PC, but ended up using an upstart product from a small company named Microsoft instead. We’ll probably never know exactly what happened, seeing as the author of CP/M is dead and his business partner is no longer able to recollect those events from the 1980 timeframe, and IBM and Bill Gates have no reason to embarrass themselves by revisiting the story.

But CP/M was the first and most popular operating system for early 8-bit computers, so people who used it remember it fondly, and the way Microsoft steamrolled it made Gary Kildall and his operating system folk heroes to underdog lovers everywhere. Even people who never used it and weren’t even born when Kildall’s company ceased to exist have at least a vague idea of what it was.

Toggle between two hosts files with a simple script

Dave Farquhar Windows , , , , , ,

A longtime reader wrote in asking if it was possible to easily toggle between two hosts files. There are several possible uses for this. When I’m at home, I need to address my web site by its internal, private IP address. On the road, that private address obviously doesn’t work. He wants something like this for other reasons; I believe he’s blocking ad servers with his hosts file and needs to unblock one or more servers temporarily for select sites to work properly.

This solution would make my Computer Science 203 professor rescind the B I received in his class if he saw it, but it works, and I don’t think he reads this blog anyway.

Microsoft: No x86 apps for ARM

Dave Farquhar Hardware , , , , , , , , , , , , , , , , , , , ,

So, The Register reports that Windows on ARM will not have compatibility with apps compiled for x86. Intel has been saying this for a while, while Microsoft has been mum. So now we know.

There are arguments both for and against having an x86 emulation layer.

My first really bad day in IT

Dave Farquhar security, War Stories , , , , , , ,

Next weekend is Labor Day weekend. I can’t remember if it was one Thursday or two Thursdays before Labor Day weekend in 1997, but one of those two days happened to be the beginning of the first crisis of my career.

Whichever Thursday it was, it was getting close to midnight when my phone rang. It was Max. The print server wasn’t working. That happened a lot. That server had IBM’s Services for Macintosh on it, which never worked all that well, and, worse, tended to make the rest of the server act up a lot. That in and of itself shouldn’t have been a crisis. But I’m getting ahead of myself.

Milestone! I’ve been pirated!

Dave Farquhar Personal, Writing , , , ,

In searching for the abstract of my book, I found more than I expected: What appeared to be a pirated PDF copy of the book in its entirety. What’s worse is that it appeared #1 in Google’s search. Numbers 2 and 3 were various pages on my site, #4 was my Wikipedia profile page, #5 was O’Reilly’s page, and #6 was Amazon’s page. So it’s easier to download a pirated copy of my book than it is to buy it. (It’s $2.03 at Amazon right now. Maybe I should buy some copies.)

I’m having trouble deciding whether that bothers me. The likelihood of me ever making another 25 cents off that book is slim. There was some talk at one time of releasing the book under some kind of Creative Commons license, but I never received the paperwork so I guess they changed their mind. As far as I know, it’s still under copyright.

And the copyright doesn’t belong to me, so ultimately it’s not up to me. I wrote it, but O’Reilly owns the copyright. So I e-mailed O’Reilly to ask them if they care.

Windows, ARM, emulation, misconceptions and misremembered history

Dave Farquhar Hardware , , , , , , , , , , , , , , , , , , , , , , , , , ,

I keep reading stuff about Windows and ARM and, well, I think people just aren’t remembering history.

I’m not saying that Windows 8 on ARM will save the world, or even change it substantially. It probably won’t, since Microsoft tends not to get things right the first time. But will I automatically write off the project? No. It could prove useful for something other than what it was originally intended. That happens a lot.

But I’m more interested in clearing up the misinformation than in trying to predict the future.

Disadvantages of Windows 98 and 98SE

Dave Farquhar Windows , , , , , , , , , , ,

Many years ago, I wrote about the disadvantages of Windows 3.1 because I started noticing people searching for that. Now, I see people asking the same question about Windows 98. I spent 9 months of my life ripping Windows 98 apart and putting it back together again and writing about it, so I know it well.

As much of an improvement as Windows 98 was over Windows 3.1 and even Windows 95, it, too, is feeling the effects of time. Windows 98SE was the best of the Windows 9x series (better than its successor, Windows ME), but there are better things to run today.

How to secure a computer like a spook

Dave Farquhar security , , , , ,

A link to the National Security Agency’s (NSA) guidance on hardening operating systems has been floating around various blogs today. But the NSA’s guidance on configuring Windows 7 and other recent operating systems is, to put it mildly, a bit incomplete.

What one government agency doesn’t do, another probably does. That’s usually a safe assumption at least. Enter the Defense Information Systems Agency (DISA). If you want to harden recent Windows operating systems, visit http://iase.disa.mil/stigs/index.html for guidance.

How CPU multipliers came to be locked

Dave Farquhar Retro Computing , , , , , , , , ,

It was 1996. I was a senior in college, and I went to the computer store in the student commons to get a cable or something. I ran into an old classmate working in the store, who went on to work as an engineer for Boeing. We talked for a few minutes, and he told me about a web site that I just had to visit. I still remember the URL for some reason. He grabbed a piece of paper and scrawled “http://sysdoc.pair.com” on it.

It was my introduction to the world of PC hardware enthusiast sites. That mysterious URL was the early address of Tom’s Hardware Guide. The front page mostly consisted of links to articles telling you how to overclock Pentium CPUs using undocumented jumper settings on Asus motherboards, and the ads were largely mail-order houses offering specials on Asus motherboards and low-end Pentium CPUs.

The tyranny of consumerization is real

Dave Farquhar security , , , , , , , , , , , , , , , , ,

Computerworld cites the Ipad 2 and increasing demand by end users to use such consumer devices in corporate environments as “The tyranny of consumerization.”

This has happened before. And if history repeats itself, the future will be better than today, but the road there is going to involve some pain.
