So you BB people still think iOS has no true multitasking?

The question: I am connecting my trusted mid-range ($1xx-2xx) X brand monitor to my shinny high-end ($2xxx) Macbook Pro with a very expensive Mini DisplayPort to HDMI/DVI cable, but (OMG!!!) the the text is not crispy, it is blurry, it is fuzzy. What am I doing wrong???

The answer: Nothing is wrong.

I found myself needed (or wanted) to check badblocks of a hard drive from time to time, and I always forgot how to perform such task ;)

I have seen a rule in Python’s Makefile

-PYTHONPATH=$(DESTDIR)$(LIBDEST)  $(RUNSHARED) \
    $(HOSTPYTHON) -Wi -tt $(DESTDIR)$(LIBDEST)/compileall.py \
    -d $(LIBDEST) -f \
    -x 'bad_coding|badsyntax|site-packages|lib2to3/tests/data' \
    $(DESTDIR)$(LIBDEST)

The dash in front of the command is to let `make` never mind the return value of the command and continue executing the next command.

I think this can be a huge step forward and it could be very risky at the same time, so other language should wait and see how it actually becomes before making any decision.
