I was thinking the same thing.

A friend was at a US trade show and, while setting up the booth,
realized that he neglected to bring the required Robertson
screwdriver. So he had to wander around the show floor trying to
figure out who else was a Canadian company.

I've removed numerous torx screws, in a pinch, with a regular screwdriver if
they aren't too awfully tight; it seems you can usually find an angle and a
screwdrive that'll work.

On the other hand, allen (hex) socket screws are hard to deal with without the
proper tool.

Phillips screws are actually designed to cam out of the screw head before
enough torque can be applied to risk shearing off the screw head. That made
sense back when power tools didn't have clutches on them, but it does tend to
instead lead to a lot of stripped screws. For use with hand tools, I find
Pozidrv screws preferable in that they don't cam out... yet with a hand tool
usually there isn't much risk of shearing off the screw head either.
(...although an impact driver makes it unlikely to strip Phillips head
screws...)

REXX on a MCU would be perverse indeed.

Actually, you can get it for Linux/Cygwin as well (known as Regina).

But it's not my usual tool of choice. On the mainframe however, we
don't have much else that compares. I found it useful for testing
complex REXX scripts before moving it back to the MF. Otherwise,
I much prefer awk.

Admittedly I'm not sure if they are Pozidriv, but I have sheared heads off
stainless steel sheetmetal screws. Apparently, aluminum is sticky stuff,
the threads sieze and off goes the head. (Note: sheetmetal, so they're
forming the thread in situ.) I find it odd that stainless fasteners are
that much weaker than their mild steel counterparts (which went in just
fine). Though I'm sure it doesn't hurt that galvanizing has a high
pressure lubricant effect.

I have had more trouble with removing Phillips screws than all the
rest put together.
Inserting a Phillips screw - fine. The screwdriver is pushed into the
screw in the same direction the screw is required to travel.
To remove the screw the screwdriver must be pushed into the
screw against the desired direction of screw travel.
An old assembly, perhaps a little corroded or even just stuck and
the screw can strart to 'spin'.
The *@;*%! things have caused me nightmares.

Of course it's subjective, but I don't see how it could possibly be
simpler to have to make decisions on class layout as well as
structuring/organizing functions within a class as opposed to
structuring a small group of functions. Even if you are only using one
class, just carrying around the class baggage is a negative, in my
opinion.

Same here. A lot of Robertson screws don't seem to have the square inset
deeply enough prevent easy stripping!

I don't think I've ever seen a stripped Torx or hex socket screw.
(...although I have managed to round off smaller Allen wrenches trying to
remove really tight hex socket screws...)

Of course.

From a users point-of-view, the best programming language for
anything is one that they know. Unfortunately that applies to
any language: from Ruby, Python, C++ or Java to APL, Perl,
Basic or Forth. Everybody forgets their learning curve and
all the hacks they had to acquire over a long period of time
to work around their language's oversights and weaknesses.

That's one reason why it's very helpful to be proficient in at
least 2 very different programming languages.


IMHO. YMMV.

Nonsense.


Must have been a *long* time ago. I've used Robertson heads (a.k.a.
Square-Head-Recessed) almost exclusively at home (I use some Torx,
a.k.a. "star", as well) for about 30 years. The screws and drivers
have been sold in every hardware store I've looked for them, for at
least 20 years.


They're available everywhere.
