I've had DOS running for months at a time without a crash. Try that with Windows!

All the time. I have had Win XP machines running for more than a year. Of course it poor thing has to be behind a good firewall, such such uptimes does mean it isn't allowed to automatically retrive updates and then reboot.

In the end, almost all instabilities are caused by bad drivers, or by a cheap motherboard.

A big problem with Windows is that the drivers model is so complex - it is way harder to write a good driver for Windows than for Linux. And most hw companies has all their skills in the hw department. As soon as the hw works, they want to ship the hardware and start designing the next hardware. The end result is often strange behaviours or BSOD.


I agree that farming out the BIOS, for example, has its risks. I also agree that allowing software people to do the serious work of writing drivers is a major faux-pas. The most difficult problem is integration, and as long as SW people are allowed to live and breathe in a development environment, nothing good will come of it. They listen far too much to marketing. Marketing should not be allowed within 100K km of development. They should remain in outer space while the HW/SW/FW work is being done. Their job is to determine what's wanted, an sign off on the requirements. Once that's done, dismiss 'em or send 'em on vacation to someplace where there's no communication. Let engineers use rigorous process to perform the requirements breakdown and implementation through rigorous design.

I admit, THIS XP-based box has been up for quite some time, particularly once I put in enough memory (Every XP box I have is maxxed out on memory.) They seem to like that. From what I've read, Vista behaves itself if it has 16 GB or more of RAM, and a TB HDD or better. I don't know that from personal experience, never having sat down at Vista.

         I think that was his point?            01/01/70 00:00      
            I know            01/01/70 00:00

            Break out that DOS Computer            01/01/70 00:00      
               I do that quite often!            01/01/70 00:00

            jeeziz x kryst            01/01/70 00:00      
               So ... Why do you do all that?            01/01/70 00:00      
                  wrong choice of word            01/01/70 00:00      
                     It's just a millstone ...            01/01/70 00:00      
                  re: why?            01/01/70 00:00      
      My computer _boots_ faster than that.            01/01/70 00:00      
         DMA?            01/01/70 00:00      
      Maybe it's the amount of memory            01/01/70 00:00      
         The cost of mutlitasking..            01/01/70 00:00      
         haven't any time to waste            01/01/70 00:00      
            That would be too slow!            01/01/70 00:00      
               I see no ships!            01/01/70 00:00      
               Isn't 4k plenty for a '51?            01/01/70 00:00      
                  which '51 does have that?            01/01/70 00:00      
                     Erik would call those "deviates".            01/01/70 00:00      
                        nope            01/01/70 00:00      
                        pipelines, cars, and real engineers            01/01/70 00:00      
                           It's also pipelined.            01/01/70 00:00      
                              then it's irrelevant            01/01/70 00:00      
                  If you can ignore those features            01/01/70 00:00      
               keeping up            01/01/70 00:00      
                  I feel your pain ...            01/01/70 00:00      
                     Don't see problems - see possibilities            01/01/70 00:00      
                        Do you really want to hide from reality?            01/01/70 00:00      
                           Always hiding behind excuses            01/01/70 00:00      
                              What excuses?            01/01/70 00:00      
                                 Your excuses            01/01/70 00:00      
                                    Do you directly or indirectly work for Keil?            01/01/70 00:00      
                                       BULL!!            01/01/70 00:00      
                                          I don't harbor any animosity, but I don't like being lied-to            01/01/70 00:00      
                                             you "understand well enough"            01/01/70 00:00      
                                                I have to agree ... evaluation takes time ...            01/01/70 00:00      
                                                   this is where I think I'm the realist            01/01/70 00:00      
                                                      If only the pieces were separately available ...            01/01/70 00:00      
                                                         I can't and would never            01/01/70 00:00      
                                                            So ... Who's a simulator specialist?            01/01/70 00:00      
                                                               don't know, don't care            01/01/70 00:00      
                                                                  So why even mention it?            01/01/70 00:00      
                                                                     because someone (you?) brought it up            01/01/70 00:00      
                                       Tangential Richard at work            01/01/70 00:00      
                           the pot calling the kettle black            01/01/70 00:00      
                     that's the crux            01/01/70 00:00      
                        It's a matter of realism            01/01/70 00:00      
                           well, if you do not have the time to evaluate, your points            01/01/70 00:00      
                              I have to disagree ...            01/01/70 00:00      
                                 no need            01/01/70 00:00      
                                    That would be an ideal fix!            01/01/70 00:00      
                  no way            01/01/70 00:00      
                     but only if we both define a project            01/01/70 00:00      
                        oh, that's no proof then...            01/01/70 00:00      
                           It would be a nice idea, but how would you time it?            01/01/70 00:00      
                           you did not read what I said            01/01/70 00:00      
                              implication and how to challenge it            01/01/70 00:00      
                                 disassembly            01/01/70 00:00      
                                    Encryption module?            01/01/70 00:00      
                                    not at all            01/01/70 00:00      
                                       It's clear to see that some folks really like 'C'            01/01/70 00:00      
                                          can you only like one thing?            01/01/70 00:00      
                                             Yes, but ...            01/01/70 00:00      
                                                you can boil steak too            01/01/70 00:00      
                                                   but you don't have to do that            01/01/70 00:00      
                                                      but you just said            01/01/70 00:00      
                                       no praise, just not hate            01/01/70 00:00      
                                          That makes sense            01/01/70 00:00      
                                          not that claim            01/01/70 00:00      
                                             again you miss 'usually', 'mostly', 'often', etc            01/01/70 00:00      
                                                Not so ... exactly            01/01/70 00:00      
                                                   Based on what experience?            01/01/70 00:00      
                                                      That's not how it works            01/01/70 00:00      
                                                         maintenance is a totally different issue            01/01/70 00:00      
                                                         apples to pears?            01/01/70 00:00      
                                                            I don't need to compare/contrast apples and pears            01/01/70 00:00      
                                                               The embedded world is larger than your tiny island            01/01/70 00:00      
                                                   IF            01/01/70 00:00      
                                                      It's all about initial hardware cost, not maintenance cost.            01/01/70 00:00      
                                                         Value of investment            01/01/70 00:00      
                                                         Not Here            01/01/70 00:00      
                                                         Whose business?            01/01/70 00:00      
                                                            What do you mean by "code analysis tools"?            01/01/70 00:00      
                                                               Some important tests            01/01/70 00:00      
                                                                  Yes, those come up in HLL, but ...            01/01/70 00:00      
                                                                     Memory leaks nothing to do with HLL            01/01/70 00:00      
                                                                        Yeah, you can do that ... but it's not recommended            01/01/70 00:00      
                                                                           More way than one to create memory leaks            01/01/70 00:00      
                                                                           that is not applicable to small embedded            01/01/70 00:00      
                                                                     Way easier to analyse non-goto code            01/01/70 00:00      
                                                                        and why would that be?            01/01/70 00:00      
                                                                           General purpose languages normally allows dangers            01/01/70 00:00      
                                                                              You still don't get the point, Per            01/01/70 00:00      
                                                                                 Wrong question            01/01/70 00:00      
                                                                                    what view?            01/01/70 00:00      
                                                                                       and the answer is            01/01/70 00:00      
                                                                                       can be seen as a leading question            01/01/70 00:00      
                                                                        Careful now! Some folks like Pascal for the '51            01/01/70 00:00      
                                                                           Why?            01/01/70 00:00      
                                                                        Some things depend on your point of view            01/01/70 00:00      
                                                                           Richard has never, ever, in his whole life implemented a bug            01/01/70 00:00

                                                                     MISRA and assembly don't mix well.            01/01/70 00:00      
                                                                        you can write FORTRAN in any language            01/01/70 00:00      
                                                                           I know ... but MISRA rules are explicit.            01/01/70 00:00
