Nov/Dec 2011  Newsletter 
Condor Storage is a national mass storage and backup integrator. We pride ourselves on accurate product representation, going the extra mile for our clients and negotiating great pricing with over 24 storage vendors.

Greener IT needs push tape purchases:

The Qualstar XLS Enterprise tape library family allows for affordable, green powered backup and archival of your data. We are seeing a resurgence of interest in tape libraries now that LTO-5 tapes are affordable ($70)and hold 1.5TB per cartridge. Coupled with policy-based archival software that we have found to cost just 1/3rd that of the library hardware, cost conscious users can address spiraling growth rates and incur 200+% less energy costs vs. disk solutions. Please inquire for a quick cost illustration of a base model system with archival software. 

Note: Due to the current floods in Thailand, disk drive prices are flunctuating and we are seeing minor allocations. Now may be a good time to overhaul your backup hardware, as tape drives are not affected.

HP's Strange Obsession With WebOS For Printers

From Slashdot:

"VentureBeat's (typically unnamed) sources identifies Intel and Qualcomm as being involved in talks for acquiring the Palm asset portfolio. However, citing sources intimate with HP's negotiations, it reports that the company wants to be able to license webOS back for use in printers; it wants it so much, in fact, that the issue has become 'a crucial part' of discussions. Maybe there's something about webOS and printers that HP knows and the rest of the world doesn't."

Measuring RTOS Performance: What? Why? How?

This white paper takes a look at "typical" reported performance metrics for an RTOS in the embedded industry. It explains what these numbers signify, how they are measured, and why an embedded system designer should give particular attention to this data.

C programming, Pre-defined Macro's

A typical example of using predefined macros is for reporting error conditions in a generic macro so you can find your way in the to where the problem occurred.

fprintf (stderr, "Internal error: negative string length %d at %s, line %d.",length, __FILE__, __LINE__);

__func__ (c99) and __FUNCTION__(GCC)

Information about compile

Date and time are precious to know exactly what binary you are running, with embedded systems this come up often.

__STDC_VERSION__  (doesn't work for me, but it's in doc's)

Cleaning HTML, removing unwanted tags.

sed \
   -e 's/background-color:[ a-z]*; //g'  \
   -e 's/>/>\n/g' \
   inputfile > outputfile

In the above example, I remove any  background-color tags.

I am using \ to separate what would normally be on a single line in to multiple lines.

  In the first line it removes the tags,  background-color:[ a-z]*;   
   in the next line it adds a new line to the end of each HTML tag.  This is for some web content that's just all packed in to a single line.

Linux vs Fascism -was: Help Occupy Oakland get electricity, lights, Linux etc ...

Subject: Linux vs Fascism -was: Help Occupy Oakland get electricity,
       lights, Linux etc ...

The domination and exploitation of the world's people by the
ultra-wealthy and their corporations, governments, and media
have a strong negative effect on Linux and other free software.

Linux adoption is only a tiny fraction of what it would have
been without Microsoft's years of lying propaganda, $100,000,000
fraudulent SCO lawsuit, media censorship by threat of withdrawal
of advertising, bribed columnists and analysts, secret contracts
with OEMs forbidding sale of computers with dual-booting, etc, etc.

At the same time, the people of the World Community are gradually
waking up to the political and economic realities mostly because
of information transmitted via the Internet, which runs on free
software.  GNU/Linux and other free software are necessary for
people around the world to communicate and organize, especially
in the face of increased government/corporate efforts to censor
the Net.  We need complete user control over our software, not
corporate control as with Microsoft products.

The U.S. and allied governments have been invading and smashing
other nations and murdering millions of people in the last ten
years, using the 9/11 false-flag attacks as their false pretext.
The laws, agencies, and concentration camps are already in place
in the U.S. for its transformation to a total police state,
with arbitrary arrest, torture, and murder of American citizens.

Linux needs and is needed by the people in the U.S. and around
the world who are fighting for freedom and survival.

This conflict is by far the most important thing going on in the
world at this time.  Our species can either go down into an
eternal night of world fascism and death under control of
ultra-wealthy psychopaths, with 1% of the population continuing
to own 99% of the wealth, or by education and action we can
advance our civilization and technology so that work and its
products and profits are shared much more equally, and everyone
lives successfully.

This is the reality in which we live!  Human history is at
a turning point.  We must become aware of what's going on and
consider its implications for everything.  It is truly a matter
of life or death!

Urgent: Stop [U.S.] American censorship of the Internet

We're sending this special edition of our newsletter today because the U.S. Congress is holding hearings on horrible legislation known as the "Stop Online Piracy Act" (SOPA) which would directly attack the technical architecture of the Internet and put every website at risk of being taken offline, even due to a single baseless accusation from a copyright troll. SOPA will hit "user generated content" especially hard -- many collections of CC-licensed works will disappear. Read more in our blog post -- Urgent: Stop [U.S.] American censorship of the Internet.

To take action now by contacting officials and spreading the word, please visit americancensorship.org -- a site that CC is proud to support along with friends such as the Electronic Frontier Foundation, Free Software Foundation, and Public Knowledge.

If you're an educator, please consider signing this community letter against SOPA from the education community.

Delete oldest files in a directory

Often you need to process a list of file quickly.  This list can be from any number of sources, in this case I print a file list sorted by time , then delete the oldest ones cleaning out cruft that's accumulating on the server.

root@server:/var/spool/relay-ctrl/allow# ls -t | wc
   1527    1527   21806
root@server:/var/spool/relay-ctrl/allow# ls -t | tail -n 1450 | while read line ; do rm $line; done

so there was 1527  files lying around, and I remove the oldest 1450 of them.

I could just have as easily said keep the latest 100 by changing this to  tail -n +100

       tail - output the last part of files

       tail [OPTION]... [FILE]...

  -n, --lines=N
              output the last N lines, instead of the last 10; or use +N to output lines starting with the Nth

Alternately  I could have used the fine command and removed any files over a certain age. 

find /var/spool/relay-ctrl/allow  -mtime +30  -exec rm \{\} \;

Removes anything over 30 days old.

Testing Ping based random number generator.

If you want to see how this works read:  Generation of Random Number from PING

Below is that random number generator put in to CGI form to run under Apache.
It returns grey levels in a table to provide a visual confirmation of it's output.

If you make the effort to try this code, please leave a short comment.

It's part of a effort to demonstration the use of BASH in making CGI based Applications.


echo "Content-type: text/html"
echo "<html><body>"
echo "<table border=2 cellpadding=2 cellspacing=2>"


while [ $c -lt 32 ]

echo "<tr>"

echo "obase = 16"
ping -c 32 -i 0.2 $target |\
grep "time=" |\
sed \
-e 's/[a-z \.(),_:+=]//g' \
-e 's/\(.\)/\1+/g' \
-e 's/^\(.*\)+$/(\1)% 16/'
} |\
bc |\
awk '{print "<td bgcolor=\"#"$1$1$1$1$1$1"\">"$1"</td>" }' |\
tr -d '\n'

echo "</tr>"


echo "</table>"
echo "</body></html>"

Below is a sample of the output.
