I'm currently working on upgrading a product for the Chinese market. The target is a ARMTDMI7 with a QVGA display. Most resources I've located on the net are targeted at desktop or web programming rather than embedded devices.
Can anyone suggest some tools and
resources that might be useful?
What are the best techniques for
extracting literal strings and
communicating with translators?
I suggest looking at EasyGUI but that depends on what graphics controller you use.
EasyGUI is a tool that simplifies design of user interfaces and comes with complete source code and driver for a varity of display controllers.
For localization you can use EasyTranslate that gives the translater a graphical representation of the interface. This lets the translator see how the translated texts fit on the screen.
EasyGUI is available with unicode support aswell as right to left script.
Freetype might be good for rendering fonts.

There are many ARM microcontroller forums which will help you find what you're looking for.
Atmel has a line of ARM7 processors, and they are pretty friendly to those who make a hobby out of this, so there's a lot of information on this processor. It won't be the same, but generally the tools and libraries can be used across the ARM line so you might find some help here - you'll want to focus on the AT91SAM7 series.
If you have more specific questions, you will probably get some reasonable response here.

It sounds like you need to upgrade an existing codebase to make it support multiple languages.
If so, the fact that this is on a microcontroller shouldn't be an issue - I'd drop that fromt he title and focus on the language you're using (c?) and ask how to convert your program for internationalisation.
This is a problem many people have solved on a variety of platforms, and the fact this you're on a microcontroller doesn't mean that the same tools and such don't apply - the relevant factor is the language you're using

I'm interested is it possible to install and use Android Things(former Brillo) on custom produced hardware?
I can see from the official documentation there is preselected and certified SoMs listed, but I'm interested in using my own hardware.
Is it possible to have best of both worlds - use the familiar to me Android & Android Things but run it on proprietary hardware?
If not, what other options do I have - I researched about micropython, but apparently it seems it also comes with designated board(pyboard).
So my question is what are options to not thinks too much about the firmware on the device(and write C code), but focus on more higher-level business logic and programming languages(Java, Python).
Android Things isn't open source, so you can't put it into that isn't officially supported.
If you're looking for custom options, you will need to find a compiled language like C that works for that board. While C may be a bit intimidating, you may be able to find languages that compile to similar machine code. Rust and Go may work on microcontrollers too if you check.
I'm not too familiar with micro python. It says that it compiles to bare metal/machine code, so I believe you should be able to use it on other boards. While they may officially support the compiler for one board, the community may have support for additional microcontrollers.
I have read the documentation for the Roboforth environment from STrobotics and recognized that this a nice way for programming a robot. What I missed is a sophisticated software library with predefined motion primitives. For example, for picking up a object, for regrasping or for changing a tool.
In other programming languages like Python or C++, a library is a convenient way for programming repetitive tasks and for storing expert knowledge into machine-readable files. Also a library is good way for not-so-talented programmers to get access on higher-level-functions. In my opinion Forth is the perfect language for implementing such an API, but I didn't find information about it. Where should I search? Are there any examples out there?
I am author of RoboForth, and you make a good point. I have approached the problem of starting off new users with videos on YouTube; see How to... (playlist with 6 items, e.g "ST Robotics How-to number 1 - getting started") which is a playlist covering basics and indeed tool changing.
I never wrote any starter programs, because the physical positions (coordinates) would be different from one user to the next, however I think it can be done, and I will do it. Thanks for the heads up.
I want to make a charting control for an embedded device using Silverlight for Windows Embedded. Currently i am planning to use line shape for drawing the graph.
My question is if its a good approach(performance wise) or should i look for other options.
Or if any controls are available for SWE.
Thanks
Silverlight is not a proper answer to drawing charts on an Windows Embedded Compact device. You should go for using (or creating) a native GDI element. If performance is very important (e.g. for a fast-updating chart), you might also consider DirectDraw.
The best way in a commercial project would probably be to use a readymade component, such as this one.
You can find somebody else's experiences and advice here for pointers to what to look for when doing this yourself. If you expand your post with more details about what you are actually trying to achieve, I might give you a more detailed response.
The answer is stop using Silverlight, since Microsoft is abandoning the product. Do it in Flash—or better yet, use HTML5 and JavaScript.
In recent windows embedded applications that use windows universal apps I would highly recommend oxyplot.

These plots are the best I've found on the internet so far and very easy to use. Best of all they are free. You can get these using a NuGet Package manager which makes getting updates fairly simple.
We are developing an Application which runs on various plattforms (Windows, Windows RT, MacOSX, iOS, Android).
The Problem is how to manage the different localizations on the different Platforms in an Easy Way. The Language Files on the different platforms have various formats (some are xml based, others are simple key-value pairs and others are totally crazy formats like on MacOS)
I'm sure, we aren't the first company with this problem, but I wasn't able to find an easy to use solution o achive the possibility to have one "datasource" where the strings are collected in different languages (the best would be an User Interface for the translators) and then can export it to the different formats for the different platforms.
Does anybody has a solution for this problem?
Greetings

I recommend using GNU Gettext toolchain for management and at runtime use either
some alternate implementation for runtime reading like Boost.Locale,
own implementation (the .mo format is pretty trivial) or
use Translate Toolkit to convert the message catalogs to some other format of your liking.
You can't use the libintl component of GNU Gettext, because it is licensed under LGPL and terms of both Apple AppStore and Windows Live Store are incompatible with that license. But it is really trivial to reimplement the bit you need at runtime.
The Translate Toolkit actually reimplements all or most of GNU Gettext and supports many additional localization formats, but the Gettext .po format has most free tools for it (e.g. poedit for local editing and Weblate for online editing) so I recommend sticking with it anyway. And read the GNU Gettext manual, it describes the intended process and rationale behind it well.
I have quite good experience with the toolchain. The Translate Toolkit is easy to script when you need some special processing like extracting translatable strings from your custom resource files and Weblate is easy to use for your translators, especially when you rely on business partners and testers in various countries for most translations like we do.
Translate Toolkit also supports extracting translatable strings from HTML, so the same process can be used for translating your web site.
I did a project for iPhone and Android which had many translations and I think I have exactly the solution you're looking for.
The way I solved it was to put all translation texts in an Excel spreadsheet and use a VBA macro to generate the .string and .xml translation files from there. You can download my example Excel sheet plus VBA macro here:

Just recently I've also added preliminary Visual Studio .resx output, although that's untested.
edit:
btw also my javascript xcode/eclipse converter might be of use..
you can store your translations on https://l10n.ws and get it via they API
Disclaimer: I am the CTO and Co-Founder at Tethras, but will try to answer this in a way that is not just "Use our service".
As loldop points out above, you really need to normalize your content across all platforms if you want to have a one-stop solution for managing your localized content. This can be a lot of work, and would require much coding and scripting and calling of various tools from the different SDKs to arrive at a common format that would service the localization needs of all the various file formats you need to support. The length and complexity of my previous sentence is inversely proportional to the amount of work you would need to do to arrive at a favorable solution for all of this.
At Tethras, we have built a platform that alleviates the need for multi-platform software publishers to have to do this. We support all of the native formats from the platforms you list above, and can leverage translations from one file format to another. For example, translate the content in Localizable.strings from your iOS app into a number of languages, then upload your equivalent strings.xml file from Android or foo.resx from Windows RT to the system, and it will leverage translations for you automatically. Any untranslated strings will be flagged and you can order updates for these strings.
In effect, Tethras is a CMS for localized content across many different native files formats.
I have seen some plotting apps for ios, such as Graph It and Quick Graph. I am wondering what libraries they are using for creating plots and how to integrate those libraries into ios apps. Thanks a lot and happy new year.
I don't know the answer for those specific apps, but I can think of some things for you to look at. One is gnuplot--the trouble here might be getting it into suitable form to use as a library rather than using it as a command-line tool, since AFAIK there is no NSTask or fork()-ing under iOS. Another would be to embed PERL; the only real hard part of plotting is evaluating the expression to be plotted, which is trivial in something like PERL. And of course there are other libraries dedicated to expression evaluation which may be more suitable, depending on exactly what you want to plot.
