There is no one true language. Learning more languages is good.

A long time ago, I was talking with a colleague about C code. I
used indentation to indicate the structure of the program to
myself. I used curly braces to indicate the structure of the
program to the compiler. My colleague thought this was strange.
He used curly braces to indicate the structure of the program to
himself and he did not pay attention to indentation. I thought
that was strange.

So I removed all the curly braces from my C code, and changed the
Makefile to insert curly braces based on the changes in
indentation. The code worked fine. I showed it to my colleague.
He was puzzled. He said it could not work, even though he saw it
work. Later, when I heard that Python used indentation to
indicate program structure, I smiled.

Did Cover My Meds outstrip the supply of good Ruby talent in Columbus?
Are they opening an office in Cleveland to get more talent?

Will Red Hat require 4 gigabytes for /boot partition?

There sure is much activity in tiny cheap computers that run Python.

Raspberry Pi Model B+ V1.2
    CPU chip is solder to board
    RAM chip is soldered to top of CPU chip

    CPU chip might be a very thin circuit board

Raspberry Pi 2, Model B
    CPU chip is soldered to top side of board
        it is thicker than of B+ V1.2
        looks like conventional black epoxy
    RAM chip is soldered to bottom side of board

U8 and U16 or Raspberry Pi 2 are bare die.
Bright light on them (such as from camera flash)
causes Raspberry Pi 2 to crash.

It had a wierd problem that went away while light shined on the EPROMs.

make business card size cards for geek groups with contact info
had an opportunity for such today, but did not have the cards

    CohPy
    cohpy.org

    weekly dojos on Friday evenings
    weekly lunches on Wednesdays
    monthly meetings with presentations

    maybe simplify the stuff on the card to a single URL
    which has links to everything else

Make SDHC flash memory in Raspberry Pi to last long time
    mount RAM drive on /var
    mount read-only flash partitions noatime

personal cards

    with keys in text and QR codes

When using dd to write to a raw USB flash drive,
how does one know when the data was actually been written?
There is no LED on the drive.
No partitions are mounted during the operation.

Who has a 3840x2160 monitor that needs to be tested with a RPi 2
(or vice versa)?
Build a Large-Screen Command Center with the RPi 2

That might make a nice X terminal.

has a 3840x2160 monitor. Loves it. It improved his productivity.

It even has a SATA connector!!! Wow!!!
With the ethernet jack, it should be good for clusters.

With these (ARM) low-end computers beginning to run regular Linux distros,
I wonder how Intel will respond in the market.
I recall that they used to make some ARM CPUs, a long time ago.

For a compute cluster, which has best computational power per dollar?
    Pi 1 / $20 (with one 700 MHz core)
    Pi 2 / $30 (with four cores at 900 MHz)
    pcDuino3 Nano Light / $15 (with two cores at 1 GHz)

Hmmm. Haven't seen Pete for a while.

Many languages were derived from C.
Some non-C derived languages are:
    COBOL
    Fortran
    PL/I
