Calculators vs. PDAs
Posted by Nick on 13 June 2002, 01:22 GMT
CNN has recently put out an article (discussion also on Slashdot) regarding the slow but definitely palpable convergence of graphing calculators and PDAs. Since TI has essentially cornered the graphing calculator market (others would be quick to debate that, but it's what I think), the article places major focus on their business strategy (FLASH on the 83+, Voyage 200, and so forth) and its relation to Palm's inclinations towards mathematical applications and suchandsuch. This is definitely worth mulling over and discussing. Go!

We can all agree TIs are better, I mean, there is an Internet Browser for the TI-83 and 83+! but sometimes I wish TI made EXPANSION SLOTS for the TI models that have risen since 1997, since PALM was founded then, and I think there were expansion slots back then. And also in hand-held models, and a 33-MHz processor, but in other terms, TI calculators are 100% CUSTOMIZABLE AND CHEAPER. I mean, you can learn to program, and make your own programs that would fufill a need, unlike the Palm, except for Palm programmers. Plus, you have tons of FREEWARE. Look how much archives the TIcalc.org has! and at $100 or so cheaper than the TI-83 Plus, heck. We should all get TIs instead of Palms

Even Linux is not unbreakable. I remember when I tried Sasteroids from Slackware 3.1, it crashed whole system (Micron Millenia Pentium 200, with 16 M RAM). If telnetd was not starterd, only power down helped.
Also, some programs under DOSEMU can do the very similar kind of crash.
However, the most dangerous can be faulty device drivers, because they are compiled inside kernel.
Actually, when speaking about uncrashable OS, the real question is: What does it mean uncrashable?
Possible answers:
a) No need to press reset at all
b) You need to press reset only if your application crashed, but not the OS
c) After powerdown system continues normaly
d) System can work for years without power off
e) Replacing system files caused minimal damage
Now, if you choose one of those critherias and if you compare different OS-es, you will receive different answers which one is the most uncrashable.
With MS DOS, or on TI calculator you need to press reset button quite often if your application is bad, but not in other cases.
With Linux, Windows 9x/NT/2000/XP you will rarely press reset button at all, but the causes of crash can be several, not only the program you have started.
On TI calculator you can not screw up operating system because it is in ROM (forget for the moment dirty methods of Julien M.). With DOS there are only 5 critical files, while on Linux and Windows there are about 200 critical files and therefore they are less prone to damage of system files.
