Apologies if the answer to this question is already all over the internet, I just couldn't find an answer which was sufficiently dumbed-down for me to make use of it.
I'm making an app in PyQt for scientific computation purposes and I thought it would be nice to give the user that extra level of control and transparency into the workings of the app by attaching a python interpreter to the app.
The idea is that the interpreter should be able to access all variables that the app is also running on. In other words, I want to be able to start my PyQt app, and immediately write in the console 'print(someVariableKnownToTheApp)' and view the output as if written in the debugger in pycharm.
Doing a bit of searching online, I came across the classes 'InteractiveInterpreter' and 'InteractiveConsole' in the 'code' package, but I'm not sure how I would use these for my purpose.
Any help or suggestions would be highly appreciated.

I have some source code for the BaNa Noise Resilient Pitch Detection Algorithm downloaded here, and I am planning to use the code they provided as a library for a mobile app I'm making. It's written in Objective-C for MATLAB and so I'd probably need to deploy it to a DLL to be able to use it for external applications.
The only thing is that I'm a student, and I don't really have the funds to purchase MATLAB just to be able to work with this algorithm, and so I'm downloading Octave, which was a suggested alternative. This should be able to make working and editing the code for my research possible, but my concern is if I can deploy the code into usable libraries for the application in which I'm going to make using the Unity Game Engine.
I'm not sure if the direction I'm going at will bring me to a dead-end or not, so I'd like to ask for insights regarding this.
What I have now:
1) Source code in MATLAB (.m files)
2) Octave (currently downloading, I'm not even sure if it has the built-in methods I need)
What I plan to do:
1) Use Octave to edit code and test out if the code I have works
2) Deploy it to a DLL file (Is this even possible with Octave?)
3) Use that DLL in Unity3D
Would you guys have any suggestions, alternative workarounds, or foreseeable problems I may encounter with this? Any advice would be greatly appreciated.
Thank you in advance,
Justin
Depending on what functionality from MATLAB (and especially toolboxes), the code should run just fine in Octave, maybe with some minor modifications. If however, the code relies heavily on some toolbox functionality that has not been implemented in Octave, then you have a fair amount of recoding to do.
There is not easy way that I know of to generate a DLL from Octave. Having said that, have a look at How do I create a simple Octave distributable without installing Octave and this section of the Octave documentation on the subject of generating standalone programs from Octave, it might point you in the right direction.
I've been tasked with testing a Windows program that is essentially a collection of links to various exe files. My job is basically to click all the links to make sure they work (yay!). To makes things a bit easier on myself, I want to create a simple script that will do the clicking for me. I have a programming background (familiar with C/C++, Java), but have never scripted anything before.
Despite googling and searching around on stackoverflow, I wasn't able to find anything that explains what would be involved in creating something like this. I downloaded a program called AutoHotKey (http://www.autohotkey.com/) that seems promising, but before I dive into it I want to see what suggestions you all have.
Thanks!
Never tried autohotkey so I can't give you feedback. But I played around a bit with Sikuli which is agnostic of the UI technology used (working with image recognition). It works fine and you should be able to come up with a working prototype in a couple of hours.
HP Unified Functional Testing (http://www8.hp.com/us/en/software-solutions/unified-functional-testing-automated-testing/) provides similar functionality as Sikuli. As licensed software, it isn't free, but provides a lot more features and support than Sikuli (which is open source) does.
I’m new to Qt Quick. So, This might sound like a dumb question. But I’m struggling with this.
I want to develop a complete UI for my embedded system using Qt Quick. So, I need QML to run my system.
Now, which library to install on my target embedded linux system.
I ‘ve seen this page : http://qt-project.org/downloads but it shows the library with 228MB! which will float my system size abnormally. I expect my system to be around 50MB only! I think this comes with lot of things which I may not want.
I may use qml, for internet browsing purpose parts of webkit (webkit module for qtquick)
xml.
So, Can you please help me which to install? & how??
Thanks & Regards

Check http://qt-project.org/doc/qt-4.8/qt-embedded-install.html for a initial documentation.
Please note, that this will install everything, meaning all Qt modules. You might be able to strip some of them away, also you might now need all image plugins. However, as a start this should work for you.
I need to build a fairly simple app but it needs to work on both PC and Mac.
It also needs to be redistributable on a disc or usb drive as a standalone desktop app.
Initially I thought AIR would be perfect for this (it ticks all the API requirements), but the difficulty is making it distributable, as the app would require the AIR runtime to be installed to run.
I came across Shu Player as an option as it seems to be able to package the AIR runtime with the app and do a (silent?) install.
However this seems to break the T&C from Adobe (as outlined here) so I'm not sure about the legality.
Another option could be Zinc but I haven't tested it so I'm not sure how well it'll fit the bill.
What would you recommend or suggest I check out?
Any suggestion much appreciated
EDIT:
There's a few more discussions on mono usage (though no real conclusion):
Here and Here
EDIT2:
Titanium could also fit the bill maybe, will check it out.
Any more comments from anyone?
EDIT3 (one year on): It's actually been almost a year since I posted that question but it seems some people still come across it every now and then, and even contribute an answer, even a year later.
Thought I'd update the question a bit. I did not get around to try the tcl/tk option at the end, time constraint and the uncertainty of the compatibility to different os versions led me to discard that as an option.
I did try Titanium for a bit but though the first impressions were ok, they really are pushing the mobile platform more than anything, and imho, the desktop implementation suffers a bit from that lack of attention. There are also some report of problems with some visual studio runtime on some OSs (can't remember the details now though).. So discarded that too.
I ended up going with XULRunner. The two major appeals were:
Firefox seems to work out of the box on most OS version, so I took it as good faith that a XULRunner app would likely be compatible with most system. Saved me a lot of testing and it turned out that it did run really well on all platforms, there hasn't been a single report of not being able to start the app
It's Javascript baby! Language learning curve was minimal. The main thing to work out is what the additional xpcom interfaces are and how to query them.
On the down side:
I thought troubleshooting errors was a sometimes difficult task, the venkman debugger is kinda clunky, ended up using the console more than anything.
The sqlite interface is a great asset for a desktop app but I often struggled to find relevant error infos when something didn't work - maybe i was doing it wrong.
It took a little while to work out how to package the app as a standalone app for both PC and Mac. The final approach was to have a "shell" mac app and a shell pc app and a couple of "compile" script that would copy the shells and add the custom source code onto it in the correct location.
One last potential issue for some, due to the nature of xulrunner apps, your source code will be deployed with the app, you can use obfuscation if you want but that's something to keep in mind if you want to protect your intellectual property
All in all, great platform for a cross-platform app. I'd highly recommend it.
Tcl/Tk has one of the best packaging solutions out there. You can easily wrap a cross-platform application (implemented in a fully working virtual filesystem) with a platform-specific binary to get a single file executable for just about any modern desktop system. Search google for the terms starkit, starpack and tclkit. Such wrapped binaries are tiny in comparison to many executables these days.
Many deride Tk as being "old" or "immature" but it's one of the oldest, most stable toolkits out there. It uses native widgets when such widgets exist.
One significant drawback of Tcl/Tk, however, is that it lacks any sort of printing support. If your application needs to print you'll have to be a bit creative. There are platform-specific solutions, and the ability to generate postscript documents, and libraries to create pdfs, but it takes a little extra effort.
Java is probably your best bet, although not all Windows PCs will necessarily have Java (most should). JavaFX is new enough you can't count on it - you'll probably find a lot of machines running Java 1.5 or (shudder) 1.4. I believe recent Mac OS still ships with 1.5 (latest version may have changed to 1.6).
Consider JavaFX
It would run everywhere with a modern JRE ..!
AIR could be an option, but only if you don't mind distributing two different files (the offline runtime installer and your app), and expecting the user to run one and then the other. You do have to submit an online form at Adobe's site saying you agree to distribute the offline installer as-is, rather than digging out individual DLLs or whatever, before they give you the installer.
Unfortunately there's currently no way to get both an AIR app and the runtime to install from one file though. I'm not sure what the deal with Shu is, or whether it's doing anything that isn't kosher.
i would recommended zink. it has all the functionalities you require for desktop. however, the las time i used it it was a bit glitchy.
i was hung up by trying to write a 6M file to the disk. thought it trough and changed the code to write 512K chunks at a time (3min work, fast).
probably it still has some little annoying glitches like making you think on root lvl but the ease of use and the features are just way too sweet to ignore.
I know this will be a difficult question, so I am not necessarily looking for a direct answer but maybe a tutorial or a point in the right direction.
What I am doing is programing a robot that will be controlled by a remote operator. We have a 3D rendering of the robot in SolidWorks. What I am looking to do is get the 3D file into VB (probably using DX9) and be able to manipulate it using code so that the remote operator will have a better idea of what the robot is doing. The operator will also have live video to look at, but that doesn't really matter for this question.
Any help would be greatly appreciated. Thanks!
Sounds like a tough idea to implement. Well, for VB you are stuck with MDX 1.1(Comes with DirectX SDK) or SlimDX (or other 3rd party Managed DirectX wrapper). The latest XNA (replacement for MDX 1.1/2.0b) is only available for C# coder. You can try some workaround but it's not recommended and you won't get much community support. These are the least you need to get your VB to display some 3d stuffs.
If you want to save some trouble, you could use ready made game engine to simplified you job. Try Ogre, and it's managed wrapper MOgre. It was one of the candidate for my project. But I ended up with SlimDX due to Ogre not supporting video very well. But since video is not your requirement, you can really consider it. Most sample would be in C# also, so you need to convert to VB.Net to use. It won't be hard.
Here comes the harder part, you need to export your model exported from SolidWorks to DirectX Format (*.x). I did a quick search in google and only found a few paid tools to do that. You might need to spend a bit on that or spend more time looking for free converter tools.
That's about it. If you have more question, post again. Good Luck
I'm not sure what the real question is but what I suspect that you are trying to do is to be able to manipulate a SW model of a robot with some sort of a manual input. Assuming that this is the correct question, there are two aspects that need to be dwelt with:
1) The Solidworks module: Once the model of the robot is working properly in SW, a program can be written in VB.Net that can manipulate the positional mates for each of the joints. Also using VB, a window can be programmed with slide bars etc. that will allow the operator to be able to "remotely" control the robot. Once this is done, there is a great opportunity to setup a table that could store the sequencial steps. When completed, the VB program could be further developed to allow the robot to "cycle" through a sequence of moves. If any obstacles are also added to the model, this would be a great tool for collission detection and training off line.
2) If the question also includes the incorporation of a physical operator pendent there are a number of potential solutions for this. It would be hoped that the robot software would provide a VB library for communicating and commanding the Robot programatically. If this is the case, then the VB code could then be developed with a "run" mode where the SW robot is controlled by the operator pendent, instead of the controls in the VB window, (as mentioned above). This would then allow the opertor to work "offline" with a virtual robot.
Hope this helps.
