I use the yellow background to read because it is easier on my eyes.
Did not know Thunderbird was transmitting it as well. I never see it

The real computers are still out there, still being made, and still

No. That class was created to serve a specific purpose WHICH STILL
EXISTS TODAY. Focusing on a hobby platform is viciously ill-advised.<br>

<pre>I never claimed it isn't. In fact, there is a flag to set the endianness.
When I said "most machines are little-endian", I was referring to machines Qt
runs on and, therefore, would use QDataStream. The fact that the default is

No. Taking a disposable chip's view of the world is
short sighted and completely invalidates the
historical reason for the class. It was created to
feed real computers which operate in Big-Endian.<br>
<br>
Read up on seismic testing or stuff happening with the
Super Colliding Super Conductor. In the case of SCSC
many thousands of disposable chip "sensors" running an
application to pick up one or a few certain readings
are streaming that stuff back to the only box which
can handle them, big iron. IBM was never the fastest
computationally, but when it comes to data throughput
to/from disk they are a 14" city water main and their
nearest competitor is happy the one day per week they
achieve being a fire hose.<br>
<br>
Here's a delightful little book about oil well
drilling. I've read mine many times.<br>
<a class="moz-txt-link-freetext"

target="_blank" moz-do-not-send="true">http://iliosresources.com/downloads/come-drill-a-well-in-my-backyard/</a><br>
<br>
In today's world "Big Oil" uses satellites to identify
"potential" places with oil reserves. For anything
above water they then go through the long, arduous
journey of getting permits to do seismic testing. Such
testing involves drilling thousands of shot-holes
(depending on the size of the potential reserve). Some
have actual shots put in them with a blast sensor
built using a disposable chip behind them to
control/ensure/measure the blast. (Dry fires happen
and the test analysis software has to be made aware of
it.) A large percentage of these sensors will simply
be lost, hence the need for disposable chips. They
used to use Z-80, then for years INTEL x86 was the
ultimate throw away chip. Now it is moving to ARM
since you can get a Raspberry Pi for $15 or less when
bought in 100 quantities.<br>
<br>
Don't assume the class was created for use within the
world of the disposable chip.<br>
<br>
That particular class was designed so Qt on disposable
chips could provide real computers an actual service.<br>
<br>
Oh, here's a wee bit to add.<br>
<br>
No company or person is allowed to _own_ seismic data.
There is an industry standard format where binary data
is big-endian. Upon request, for a nominal media and
shipping fee, if you have it you have to provide it to
whoever asks. Geologically and environmentally, we
don't want 100+ companies drilling 1000+ shot-holes in
the exact same county. What you are allowed to own is
the analysis software you develop.<br>
<br>
Do NOT change the default behavior of that class. It
wasn't written for use on an iDiot Phone. It's design
was and still is far reaching. Had it not existed, Qt
would have had a dramatically shorter growth arc,
possibly not surviving long enough to make it onto
iDiot Phones. Changing the default behavior of the
class would be viciously short sighted.<br>
<br>
Sorry, I don't mean to sound insulting, but, in this
particular case you are a grain of sand on the beach
trying to remove the ocean because it gets you wet.
