Chit chat

Some of us in IT have spent a lot of hours and expense getting educated. Some also have a lot of practical experience. IT people are more than just Googlers. In the corporate environment, IT spend a lot of time setting machines up. To have users try to repair a setup could do more damage than good.

#God is a single #father. No wonder he does not have time to fix all the problems.

Play on “Once I built a railroad”:

Once I built a network,

Made it run.

Made it race against time.

Once I built a network,

and now it’s done,

Brother can you spare a paradigm.

Did you know that you can use the thermistor from a personal computer fan to tell relative temperature?

Sharks Cove board with Intel Atom CPU targeted at Windows developers.

One really thinks this is aimed at the Raspberry Pi/Arduino market. But at $300 dollars, who is really going to choose it. Microsoft  has a tradition of not supporting speciality products for any period of time. Zune and etc etc etc. Even if it was worth it I would shy away from it. Ironically you can take a pico motherboard and dc-dc power supply and in effect have the same thing for a fraction of the cost.

Now if you really want to get inane on this, I will take my old 486 laptop and add all kinds of breakout cables to do quite a bit. Parallel, serial,  vga, and etc. The 486 laptop was free. Cables did have some cost to them, but no where near $300. If you know anything about electronics, a “1” is plus five volts and a “0” is near zero volts. That is true for the Raspberry Pi, Arduino, personal computers, and a zillion developer boards. Not all interfaces will be using digital, but you get the idea.

Run my robot on an old Pentium 1 with linux as the os. With a laptop or most any standard legacy machine you can add a variety of interfaces:

Parallel

Serial

Vga

Plus others such as usb. Also consider:

It’s your choice!

Old electronics can yield quite a lot of good equipment. For example an old 5 1/4″ drive can yield stepper motors. You just saved twenty dollars.

Many people have created tutorials on http://www.instructables.com. To see how each instructable is doing can be a chore. Devised a bash script to help conquer that chore. Though may not be the latest, it certainly shows viable trends. You can also import the data into a spreadsheet rather easily.

First you will want to create a text file with the instructables you want to follow.
One url to a line.

http://www.instructables.com/id/Line-editor-template/

You may need to install a program or two such as elinks and zenity so things will work. Then you will want to create an executable of the file to collect the data.

#================================
#
#  Instructables numbers catcher
#
#=================================
# Assignments
# ——————————–
szAnswer=$(zenity –file-selection –title=”Select a iurl file to read”)
datafile=$szAnswer
outfile=”inumdata”
total=0
# the date
tmon=$(date +”%b”)
tday=$(date +”%d”)
echo  “The views for $dj on $tmon $tday:” > $outfile
#=================================
#
# Data input
#———————————
while read line
do theurl=$line
echo  “$theurl”
# echo -n “$theurl'” >> $outfile
# get total views
# count=$(elinks  “$theurl” | grep -m 1 “hits-count” | sed ‘s/[^0-9]*//g’)
count=$(elinks  “$theurl” | grep -m 1 “views” | sed ‘s/[^0-9]*//g’)
# let total=$total+$count
echo “$count” >> $outfile
done < $datafile
# echo “total: $total” >> $outfile
zenity –text-info –filename=$outfile

Then it is a matter of running the script.

Just copy and paste the data into the spreadsheet.
