This requirement is not as silly as the examples you give, because it can easily be rewritten in a positive way. Something like : "While cutting and pasting file pathes, the directory separator should be handled correctly : the application running in a unix envionment should handle windows directory separator, ande vice-versa"
If you want to be positive, you should propose this to your client. and explain that "no screw up" is a very vague and fuzzy requirement.
Nothing is funnier than requirements which state things that are not to happen. An actual quote. ... don't screw up cutting and pasting and the "/" vs "\" depending on unix / windows. Why not list everything that's not suppo...

Two years ago, +Jack Diederich told me to stop writing classes. Now, +Alex Gaynor tells me to specialize my dicts into classes if I want him to speed-up my programs.

 +Chris Lasher : Thanks for your interesting link.I agree on "stop writing stupid classes".. But the difficulty is is to recognize stupid classes, and your post gives good clues.

On the class/dict point, I think that one majour criteria is semantics and expressivity. In #python , technically, many many things are, in fact, dicts (with some syntaxic sugar). Designing appropiate objects is a way to give information to partners (re-reader, optimizer , ...). Python code with overuse of dicts may just be a variant of Lisp, in which everything is a list.

OK, la conductivité thermique est quasi-nulle.
Mais le rayonnement thermique doit chauffer un peu, quand même. Personne n'approche ses mains aussi près des chauffages rayonnants (du type de ceux qu'on voit pour  terrasse ou de marché)

2,200 Degrees Yet Cool Enough to Handle

A very cool (pardon the temperature pun) demonstration of LI-900 in action. This is the stuff that the Space Shuttle tiles are made from.

They are composed of 99.9% silica glass and are 94% air by volume. That means that they are incredibly bad heat conductors, making those edges safe to handle with bare hands.

They can also be submerged immediately into cold water and suffer no damage. Pretty neat, huh?

We thought so, and since we love all things  #science   and  #space   here at www.solarvps.com - we figured it was definitely worth a share.

Hope you all are having an excellent  #monday  !

Impressionnante perspective !
 
Waterspouts are spinning columns of rising moist air that typically form over warm water. Waterspouts can be as dangerous as tornadoes and can feature wind speeds over 200 km per hour. Some waterspouts form away from thunderstorms and even during relatively fair weather. Waterspouts may be relatively transparent and initially visible only by an unusual pattern they create on the water. The above image was taken earlier this month near Tampa Bay, Florida. The Atlantic Ocean off the coast of Florida is arguably the most active area in the world for waterspouts, with hundreds forming each year. Some people speculate that waterspouts are responsible for some of the losses recorded in the Bermuda Triangle.

Il semble qu'il y ait encore besoin de faire des articles pour rappeler ce qui me semble une évidence : faire vivre la francophonie, c'est créer des contenus de qualités et accessibles, pas polémiquer sur la pratique de la "lingua franca" de notre siècle.
