I was asked to obtain some aerial photography from a WA state agency. I

requested TIFFs as they come out of the camera as this had meta data

that can be used to stitch the strips together. I had made this clear,

but what I got was photoshopped Adobe "JPEGs". My intention was to

make JFIF JPEGs with the size and balance that I wanted, but what I had

got was already JPEGed!

Some sources of data are plaintext. This is least obfuscated form of

data. I was told that they will be helpful and paste it in Excel and

then send you an XLS or worse still an XLSX of it!

These are examples of undisclosed software being used to change data.

Perhaps government agencies can not read my plaintext email as they are

The plaintext version of text/plain media type is described in RFC 20,

822, 2045, 2046 (4.1 Text Media Type), 2822 and 5322. The precedents
+
for plaintext go back to teleprinting. In the earliest form you cut
+
ticker tape on space and that multiple spaces are paragraph breaks
+
where you skip a line. This was done later with CRLF and CRLFCRLF by
+
TTY operators. Similar plaintext is also the source code basis of
+
software.

CMOS CPUs are clocked much faster than thermal limits permit so they
+
must slow down as they heat up. When processes have yielded the CPU
+
stops and cools down. This means that the CPU can run much faster in
+
bursts than it could in continuous operation. This mode of operation
+
was first used in CMOS mainframes where a valid process will yield for
+
IO. Something similar was done in calculator key-press, get, process,

update display and then sleep to save battery power.

Linux has the ignore_nice_load feature which stops nice jobs breaking
+
power management that must now be regarded as essential. Linux does not
+
usually stop, but it does slow the CPU down. This cools the CPU and
+
allows it to burst up to full speed when priority jobs become ready.
+
 
+
When you are running stuff like https://boinc.berkeley.edu/ you may not
+
want it to slow down your apps. Running it nice alone will not prevent
+
your apps from being slowed down. You need to give your CPU a chance to
+
cool down so that your apps can run faster.

Jan studied Computer Engineering and Computer Science at the University of Newcastle Australia and has nearly 30 years experience in software development. He specialises in embedded and distributed software system design and implementation.

He is a GStreamer maintainer and primary author of DVD playback support, but has touched most areas of GStreamer at some point. In the past he worked for companies including Canon, Fluendo, Sun Microsystems and Oracle. Among other things, he has done research for new laser printer engines, implemented multimedia redirection for thin clients, written video and audio encoders and decoders and been a web developer.

He lives near Albury, Australia along with a menagerie and in his spare time builds 3D printers, robots and home automation systems
