How famous is the NumericalChameleon
The Version 1.6.0 of the NumericalChameleons has been published in many professional IT journals. Many journals have bundled a media. Actually there are more than one million CDs and DVDs where you can find the NumericalChameleon. In addition to that there are more than 100,000 downloads on sourceforge.net. Nonetheless there are still billions of users out there who have never ever heard about the NumericalChameleon. If you are happy with the application, please tell your friends and family about it.
It is too early to publish any download statistics for the version 2.0.0 of the NumericalChameleons, because it is still too new.
The software is copyrighted and it has been released under the conditions of the GPL v3 or later.
Why the GPL
The license gives you the freedom to run the program, for any purpose, to study how the program works, and adapt it to your needs, to redistribute copies, and to improve the program, and release your improvements to the public. The GPL guarantees those freedoms, because you are required to license your work under the same license if you adapt the work.
my Windows x64 I have installed both a 32 bit JRE and a 64 bit JRE,
but the NC always starts with the 32 bit JRE although I have
installed it with /64
The install option called /64 has installs the NC to the preferred location for 64 bit applications (if you didn't change it during the installation). However, if you have installed the 32 bit JRE after the 64 bit JRE, the 32 bit JRE will be used since the last installed JRE will win. Solution: install the 64 bit JRE after you have installed the 32 bit JRE. Alternatively you can use jarfix, which you can use to switch between a 32 bit JRE and 64 bit on demand, comfortable and quickly.
I want to use the Java Runtime Environmen from Oracle instead of the Open JDK. How can I do that on Ubuntu ?
Download the JRE from java.com and install it, for example to
Run update-alternatives. See also https://help.ubuntu.com/community/Java
$ sudo update-alternatives --install "/usr/bin/java" "java"
$ sudo update-alternatives --config java
If you want to be flexible as possible, you could create /java/jre/64/latest8 just as a symbolic link to the actual Java folder. The advantage would be that each time a new JRE comes out you just have to update the symlink.
Does the NumericalChameleon run as Portable
App as well ?
Yes. You can even choose, whether you want to load not only the program but also the Java Runtime Environment from your USB flash drive. See also the install instructions for the portable NumericalChameleon.
Does the NumericalChameleon also run on my mobile device?
It depends what mobile device you actually mean. Any mobile computer that supports the Java Standard Edition can run the NumericalChameleon, e.g. Laptops, Notebooks, Netbooks, Tablets, etc. Devices that are not able to run it, are often in an inferior position (e.g. low equipped cell phones or the display size is too small). There are also devices that are technically equipped very well, but even not able to run it. Actually some vendors don't allow the user to download and install software from any source. In those cases your device is restricted and it is not possible to run free software on it. I recommend to go to your vendor and ask when they are going to relax the restrictions on your device that you own. The NumericalChameleon has been open sourced in September 2001 and Java has been open sourced in November 2006.
Save a webpage to a single file. If you use the Internet Explorer (IE)
or Firefox 3.6 or later, select the option "Save as type: Web Page, HTML
only" at the dialog called "Save Web Page", otherwise the browser rewrites
(destroys) the original HTML of the exchange rate provider and the
exchange rate filter (which is based on regular expressions) won't work
Alternatively you could also use an alternate web client like wget that stores the web site without modification.
Do you use UMTS? If you use UMTS to connect to the internet, your UMTS provider could optimize the webpages in order to decrease the datatransfer. In that case modified webpages are being delivered to the client. Since the NC requires the original, unmodified webpages, the filters in the NC won't work anymore. You can disable UMTS optimization. Ask your provider how that can be done. Sometimes it helps if you request the webpage a 2nd time (click Ctrl+F5 in IE) before you are going to save a webpage to a file.
Timezones: It seems that the Daylight Saving Time (DST) rules are not up to date
Update to the latest Java Runtime Environment or use the Java Timezone updater.
