I have a batch file that asks the user for three separate pieces of information. I want to make a GUI out of this for ease-of-use but I'm not sure where to begin. I have a Windows Form with three separate boxes of text and a submit button. Is this even feasible? I've seen plenty of results for passing batch arguments to VB.Net but none regarding the other way around. Clarification: My batch file prompts the user for three separate pieces of information, one at a time. I actually want to make it so that these pieces of information come from three separate input boxes in a Windows Form and then have that information get passed to the batch file in order for it to actually do it's thing. The batch file asks the user their name, the department they are shadowing, and their ID number and then places that information into the appropriate folder which is named with the person's ID and the date. I have everything figured out in the batch file and it works perfectly, I just need to integrate it in Windows Forms. TheEffect fucked around with this message at 22:53 on Oct 13, 2014 |

Modify your batch file to take those values as command-line parameters - then it will be straightforward to simply invoke it with those arguments from your program.

I'm on a team looking at building an android application, and I'm hoping to get suggestions on an optimal technology stack. There will be a centralized server application living somewhere like AWS. Users in the field will submit short reports to the server, which will be aggregated and shown to other users of the app - info like Geotag, notes, etc, simple stuff. We have a current sever application written by some students in flask/mysql that is not ready for a production environment in terms of security, scalability, etc, so we're willing to rewrite completely if needed. We need to have an application that properly deals with user management, ideally encrypts the data to be sent, and has a robust offline mode for use in limited data connectivity situations. We generally need a system with more security in mind. I'm a python developer, as my primary language, so if we're able to reasonably stick with flask as a web framework for the server side application that's fine, but I'm not married to it. I'm initially thinking about changing the server side to use a mongo backend, since we're already just passing json back and forth, bolting on https and flask-security, and letting the app itself worry about dealing with the offline mode, but I'm open to suggestions. Thoughts?

Personal preference mostly, I've had more mysql headaches than mongo headaches. Flask-security also mentions a tie in with a flask-mongo extension, and getting out of the box integration is appealing. The student code is pretty much going to require a full rewrite to meet the more secure and offline set of requirements, so I'm not tied to any currently implemented stuff.

I don't know if this is a pure math question, but how do I use linear programming to find a convex hull? I get that all the edges of the hull are like half-space constraints of the linear program, but those are the ones we're trying to find.

I have this simple html table and was wondering if I could somehow parse of bunch of text into the table to be made into paragraphs. Also I was wondering how hard it would be to have a function within the html that makes it possible to just click a button and make a new entry like that. Basically I have this table I'm always updating and it's real tiresome having to do thiscode:

Writing all the <td>s out manually is difficult. You can write a little Python script or something to generate the <td>s for you and then you can copy/paste that into your HTML file. You can also write a little JavaScript script inside the page to generate it inside the browser, but then Google won't be able to see it. What languages are you familiar with?

Any best outcome given by linear programming is going to be on the convex hull. So tweak the cost/profit function's gradient until you've got all the elements on the convex hull.

It really all depends how you've got the text and how you want it to look. Regexes are probably your friend here. If you've already got your desired data in a format like: code:Search for code:code:code:Honestly if you're using sublime text it'd be just as easy to select the text you want to work on, click the "selection" menu and hit "split into lines". You're able to edit text on multiple lines simultaneously then.

Jo posted:Basically, if you want to map to n colors (which you can get from m-bits), you create n centroids/parent nodes. You go through the whole images and, for each pixel, assign its parent to the color which is 'closest'. Closest in this case means, 'has the smallest color distance as determined by colorDist = Math.sqrt(dr*dr + dg*dg + db*db) with dr = the different in the red channel'. Then, after you've done that for each pixel, you move the centroids to the 'center of the color space', that is, average the color of the children and assign that value to the parent. Then you repeat the process until you're satisfied. Thank you, this (and the code you posted) was very helpful

I just learned a useful thing in eclipse. I have a Ruby on Rails app and eclipse as aptana installed. I started a new project and my team menu, which gives me a git interface, was all different. Turns out that the "Disconnect" option doesn't disconnect you from git remotes, it disconnects the git interpreter for the project. So I clicked that, then went back to the team menu where there were only two options, one being "share project", I clicked that, then it gives me 3 options to use for a git interpreter and I selected the Aptana stuido one. Now everything looks like how I'm used to! Disconnect and Share are weird phrases to use for those menu options. tl;dr Woooooooo, I got eclipse to look how I am used to in a new project.

I haven't had to do any data modeling in a very long time, and when I did it was a simple UML diagram. I just created my first UML activity diagram in Visio 2013 and I would appreciate it if someone would at least give me an idea if I am using Visio to do this the right way. Programming this would be infinitely easier for me. The UML Activity Diagram needs to model the following:

Is there a way in Windows Forms to make it so the pre-populated text in an input box is greyed out and when a user clicks the box the text goes away? Similar to a input boxes on a lot of websites, i.e. "Search..." and when the user clicks the text goes away.

TextBoxes don't have placeholder functionality baked in, but you're likely to find an extension of the TextBox class that does in whatever language you look for.

Ok I know this is really dumb, but my coding knowledge is mostly self-taught: Is there a name for the style of programming where the program starts, get some input from the user, and then call out to functions that do whatever it is that I need doing? More like scripting than anything else. I tend to do stuff like that as rebellion against the super-object-oriented way that I was taught in my CS minor. Each program was an object and I really hated it because it doesn't seem to make any sense to me.

And the reason CS classes go a bit overboard on the object-oriented is to get everyone used to thinking in terms of good OOP when they take later classes and need to use those techniques to develop larger software that doesn't devolve into a complete mess of god objects and mega functions.

If your program is basically supposed to be non-interactive, reading a limited-size data set in from a file/network/whatever and writing output back, and exits when all input is processed, you might also call it a batch program. But that's not really a programming style as much as a form of UI.

Nobody here would happen to be familiar with the Yelp API, would they? I'm wondering if there's a way to get a list of Restaurant subcategories (Indian, Chinese, Italian, etc.) in a specified area. I want to get restaurants in a random category, but I don't want to choose a category that isn't present in the area...does the API supply something like "put your address here and i'll tell you what categories are available!"?

Can't you just pick a different category when that happens?

I also have an issue involving non-cuisine categories like Bars or Lounges getting thrown in the mix. I may have to make a whitelist... Actually, yeah, I'd like some input. Should I stick to trying to grab the categories from Yelp, or should I make the potential categories a user-curated (or myself?) list instead?

Keep your own copy of what categories are available in an area, refresh it once in a while, fetch it from their server only if you lack a cached copy or it's old.

Would that be caching in the sense that I save that location to the database, and add categories to that location? In which case, there'd be something like two models:code:Once that's done, and assuming I know every Category available in a given area, I would then create a Location in the database (formatted as Yelp's returned search parameter), add to it all the respective Categories, and save it to the database. Then, if someone makes a request for an address, the app looks up that address in the database, and if it's there, it searches using the categories already known to exist in that area. If not, a new Location is created, and a list of categories available in the area is gotten from the server, etc etc. There's still the problem of getting what categories are available in the area - the Yelp API only returns 20 results per search, which is definitely not the same as the number of categories in the area. I might just ask them if there's a way they can implement that in their API.

You know how your phone or kinect or whatever can be listening for a key word like "Siri," or "Ok Google," and that'll kick in higher-fidelity recording to be kicked up to the cloud? I'm interested in that first bit, like a white paper or something, even a vendor bragging about the capability would be fine. I'm assuming it's low-powered, doesn't have to be trained to a particular user, and is just looking for some 'signature' of that phrase like "hard K followed by two G sounds", translated into frequencies. Like at the extreme end (i.e. gunshot detectors) it could be entirely in hardware with clever enough filtering. Is "keyword interrupts" commodity technology yet?

Qualcomm advertises it as part of their sensor suite, so I would guess it's doing just what you said and passively listening for a certain frequency pattern. I would expect that pattern to be controlled by software so the chip isn't issuing an interrupt for every sound it picks up, just a very specific set of frequencies.

It's possible this is also done with dedicated hardware, a phrase in firmware, and a small ring buffer. Integrated circuits are surprisingly cheap these days.

I don't know if this helps you in any way, but the 2014 Moto X lets you use whatever phrase you want as the hotword. Does not work on the 2013 Moto X. Not sure if that's artificial segmentation or if there's a hardware difference between the two handsets.

Considering that the X needed training I wonder if it was some kind of mapping where certain frequencies with certain timing were mapped to certain phonemes. (I know nothing about speech recognition and very little about DSP, fwiw.)

Does anyone know what re-sizing algorithm is used by StretchDIBits? I'm re-sizing a bitmap frame captured from a video using GetCurrentImage, and I need to access the pixel data after the re-sizing, but preferably not by grabbing what's displayed on the screen - I'd rather just grab the same pixels that the algorithm does before the re-sizing happens at all.
