Entry 1047, on 2009-07-06 at 21:35:51 (Rating 1, Computers)
Following on from my previous blog entry I want to say a bit more about old technology. One of the nice things about modern computers is how they can easily emulate other hardware and operating systems. The most familiar case of this for Mac users is PC emulation programs like Parallels and VMWare Fusion which allow Macs to run Windows or Linux at the same time as they run Mac OS X. But there are many other emulators out there which allow other systems to be run as well.
I'm currently converting two old programs, which I first wrote in the late 1980s, to run on modern machines. Actually, I'm writing them from the start because there was nothing worth salvaging in the old ones. But I wanted to see what functions the old programs had so I needed some way to run them on my modern Mac. Apple dropped the Classic environment when they released Mac OS X 10.5 so I needed something else.
First I tried a simple program called "Mini vMac". It turns your modern Mac into a Mac Plus. That was a bit older than what I really needed but I already had it installed so I tried it. Well after starting up a pile of really old software (MacPaint, etc) I remembered why I was there and tried to get the programs running but the Mac Plus was just a bit old for what I wanted.
So the next thing I tried was something called "Sheep Shaver" (don't ask me why its called that - weirdest name since "Chicken on the VNC" in my opinion). It took a bit of setting up (I had to get some Mac ROM code and a Mac OS 9 install CD) but eventually I got it working and it goes quite well. So that's the emulation software I will use to test my older programs.
But while I was playing with emulators I thought I would try a real classic: Virtual ][ which is a program which emulates the Apple II. Now that is really going back to the late 70s and early 80s, the dawn of the personal computer revolution.
I found a pile of old Apple II software and games (I used to program it, and the Apple III in my first programming job) and had a lot of fun with that as well. I notice there are emulators for a lot of other older computers too, including the Commodore 64 and Atari 800 so I must try those some time, just as a sort of nostalgia trip to the time when I used to play with them.
One of the amazing things about these emulators is how fast they are. Even though they have to translate the code for the original processor (PowerPC, 6502, etc) into code for the Intel processor used in modern Macs they still absolutely fly. I remember the original Macs used to take a minute or two to boot from their floppy drives. In the emulator you press the key to boot and the machine is already running before you can take your finger off the key! Its that quick!
So the performance improvements I talked about in my last blog entry are obviously true but most of the extra power has been absorbed by modern operating systems and software so we often don't notice it. Its worth it of course, because what we can do now would have seemed impossible back then. Last night I was running Mac OS X, Windows, Mac OS 9, System 5, and Apple DOS all at the same time while listening to music and browsing the web. back in the day of the Apple II it would have taken about 30 floppy disks just to store one MP3 file!
Still, I do remember having lots of fun playing with the Apple II. And I don't just mean playing games, I also mean programming it (in BASIC, Pascal and machine code) and doing other geeky things which were so much easier on that simple architecture. And I do remember spending a lot of time playing games. When I first got Wizardry for the Apple II I played for about 40 hours non stop!
But when you think back about how much fun those old games used to be you shouldn't let nostalgia for the good old days blind you. When I tried running these old games now I found them all rather boring: the graphics were terrible, the sound hideous, and the gameplay fairly simplistic. I think I made a mistake playing them because the memory definitely was better than the reality!
Gees, how obsolete is Mac OS these days? Not even mentioned... Clash of the titans
"The confrontation [Chrome OS vs Windows] is likely to be momentous. Microsoft’s PC operating system, Windows, boasts a market share of nearly 90%. Although the firm’s empire has been showing signs of decline, it remains a dominant power. Yet industry watchers see a huge threat as the mighty internet company moves into new territory. TechCrunch, a leading technology blog, made it clear how vulnerable it believes Microsoft to be, reporting the news as “Google Drops A Nuclear Bomb On Microsoft”."
Apple doesn't even rate a mention, at least Linux did.

Possibly a bias in that publication since Mac has many times the market share of Linux. Another possibility is that they don't see Chrome as such a challenge to Apple as they do to Microsoft and Linux.

As you have mentioned before market share doesn't equate to quality.
Like how you more or less write it off as "bias" so quickly. Another example of what I mentioned in the "An Open Letter" post (entry 1048) comment 5.
Comment 4 by OJB on 2009-07-12 at 12:16:51:
No, I wasn't using it as an argument for quality, just that it was surprising that Mac hadn't been included in that particular article given it is clearly in second place in market share. Nothing to do with bias (and neither was my comment in entry 1048).
Comment 5 by SBFL on 2009-07-12 at 12:27:48:
Re quality: I know you weren't but was giving you an indirect support of sorts..a case to argue. Even when I help you I get dissed!!
Re inclusion in article: Ahhh, that was my point. They _weren't_ mentioned. Not surprising really, over the decades they have failed to make an impact with their OS.
Comment 6 by OJB on 2009-07-12 at 13:15:24:
In fact the Mac OS has made an impact. It is a genuine alternative to Windows, which I readily admit is overwhelmingly the most widely used OS out there (as you said above, popularity doesn't imply quality).
Not only that but many Windows features are copied (usually rather poorly) from Mac OS and the same has happened with the iPhone OS. A 10% market share may not seem much when Microsoft is on 80% to 90% but Apple is the only alternative OS company with any real influence at all.
Also, the general trend is a slow but steady increase in Mac share against Windows. Not saying Mac will ever overtake Windows but it will continue to be very influential.
Comment 7 by SBFL on 2009-07-12 at 13:21:15:
The numbers don't suggest much of an impact, especially so over that period of time.
So what if ideas were purportedly "copied". Who is the winner at the end of the day? MacOS seems to have failed to promote their ideas.
Very, very slow considering the amount of time Mac has been around. In fact, any growth is probably within a margin of error!!

Have a look in movies and TV programs. See many PCs? Have a look at all major program categories: started on Mac. Have a look at market trends: Microsoft are gradually falling in every area, thanks to Mac to a large extent. Numbers aren't to do with sampling error either.

If you're basing your argument on the facts that Macs are shown in Shortland Street...then oh dear, you must be truly clutching at straws!
Comment 10 by OJB on 2009-07-13 at 08:34:44:
Excellent! I have tricked you into admitting you watch Shortland Street otherwise how would you know there are lots of Macs there? At least I assume there are since I don't watch it myself, of course...
Comment 11 by SBFL on 2009-07-13 at 11:25:08:
Heh, I knew you would say that, but it's too late in the night for me to think up another program. I just remember those iMacs with the fluorescent coloured backing to the monitor. Pretty old now since I assume all iMacs are flatscreen these days.
Comment 12 by OJB on 2009-07-13 at 14:34:13:
Yes, Apple was the first major manufacturer to completely drop CRT screens. I still like those original colourful iMacs though!
Comment 13 by SBFL on 2009-07-13 at 18:04:20:
I am sure smoko break chats with you in the IT staff lunchroom must be a real treat.
Comment 14 by OJB on 2009-07-13 at 21:56:25:
Oh yes, its a veritable geek-fest!
