It’s MHz, not mhz.

The last radiation hard chip that I knew of specifically (I am sure there were others), was a 6502 version (same as the old Apple II I believe).

VxWorks is not a variant of Linux… Please explain what you mean!

There exists a RTOS based Linux product… but it’s not VxWorks. And there is no code sharing or lineage that links the two products.

Please correct you article.

1- VxWorks is NOT a variant of Linux. An easy way to tell is that VxWork is proprietary (hence can not derived from a GPL linux). Another way to tell is that VxWorks was first released in 1985 that is 6 years before the first line of Linux was ever written. (or maybe you work for SCO and have a very personal definition of ‘a variant of’)

2. the 30386 was certainly not the rage in 1998 (a decade ago), in 1998 the ‘rage’ was something like a Pentium II clocked a 333Mhz. Oh well, you were just of by an order of magnitude.

3. Rad6000 is a single-board computer that include a cpu AND 128MB of ram. So it is not a ‘rumor’, it’s the specs and it’s what NASA has on its boards. And that is not ’scant’ either: back in the day where 33MHz processors were in fashion, 128MB of memory was an insane amount. Most machine at the time did not have that in Hard Drive capacity.

4. you’ve got 30 engineers producing 1000-1500 instructions a day that is 30 to 50 instruction a day per capita… That is 3 to 5 time above the unsubstanciated average of 10 lines/dat per capita, but that is discounting the years of prep-work. In other words, they do a nice work but it has nothing really that extraordinary. Furthermore the 10 lines a day claims is quite low, and certainly does not apply to a small select group like that.
As an example, that one can readily verify. linux-0.01 contained 8830 lines of code (as counted by sloccount by David Wheeler). and that was published at then end of August 1991,that is a bit less than 8 month after Linus actually bought the machine to program on it - so some of that time was spend doing other thing than coding linux, still - according to your so called ‘industry-standard’ that should have taken him 3.5 years … BTW, David Wheelers’s SLOCCount evaluate that effort to 23.63 man-month, using the COCOMO model, which seems to place the number at about 18 lines a day. Oh well, at least this time you have the order of magnitude right!

5. “This list is in the form of computer code written in a programming language called ‘C’”. That one is concievably true, but that would be quite odd and unlikely. and in the context of the rest of the ‘article’ I would ask for a bit more substanciation.

6. “NASA are doing what a regular programmer would take nearly 5 months to achieve in 24 hours!” That is Fox news reporting. NASA use 30 engineers and most certainly an awful lot of other support staff to do that. So the ‘5 months alone in your garage’ metric make for a good effect, but is meaningless.

“I have been in the computer industry for over 30 years,” Whoaa, it doesn’t show.

hah bullshit.

10 lines is a short and simple function / procedure / whatever…

If anything VxWorks looks to be similar from VRTX, a RTOS. (See the history section in the Wikipedia article.)

Wind River does supply Linux to customers, but VxWorks has been around longer than linux!

What, did you deliver the pizza’s into the building?
