  • Becoming a professional programmer / software engineer

    - by Matt
    This isn't strictly about programming, more about being a programmer, so I'm sorry if its not the right kind of question to ask on this forum (mod, please delete if it isn't) I'm a computer tech in the US Army, and once I'm out I'll have eight years on the job. I'm about to start a degree through an online school (the only way I can get the army to pay for it while I'm still in), and I'm seriously looking at getting a computer science degree. I'm great with computers. I can take one apart and put it back together with my eyes closed. I'm A+ and Network+ certified and I'm getting a couple other CompTIA certs before I get out. I can work Windows as well as anyone on this planet and I'm not terrible with Linux. A job in computers is something I've always wanted. But, aside from being a computer technician, it seems that every job in the field requires programming ability. I like programming as a hobby. I programmed TI BASIC in high school and I'm teaching myself Python, but that's as far as my experience goes. That sort of brings me to my questions: I've always heard that the first language is the most difficult, and once you learn it well then all the others sort of fall into place for you. Is that true? Like, if I spend the next eight months mastering Python, will I pretty much be able to pick up at least fair proficiency in any other OO language within a month of studying it or whatever? How easy is it to burn out? the biggest thing I'm afraid of is just burning out on programming. I can go all day long if I'm programming strictly for my own personal desire, but I can imagine it being really easy to burn out after a few years of programming to deadlines and certain specifications. Especially if its a big project involving a dozen different designers. From what I told you about myself, would I already be qualified to work as a regular technician (geek squad type or maybe running a computer repair shop). Is Python a good base to learn from? I've heard that it makes you hate other languages because they feel more convoluted when learning, but also that its a great beginner language. If you're a professional programmer, did you have any of the same fears? Would you recommend that I stick to computer repair and Python rather than try to get into corporate programming? (just from what you've read in this thread, anyway) Thanks for taking the time to read all this and answer (if you did)

  • WPF Localization file folder

    - by Jefim
    I have a WPF application with localization. In my project file (.csproj) I have added a string: <UICulture>en-US</UICulture> Now the problem is - when I compile the default localization (en-US folder) is always put to the root of $(OutDir) of the project. Question: how do I move this directory into a subfolder (say, $(OutDir)localized\en-US)?

  • How to setup a webserver in common lisp?

    - by Serpico
    Several months ago, I was inspired by the magnificent book ANSI Common Lisp written by Paul Graham, and the statement that Lisp could be used as a secret weapon in your web development, published by the same author on his blog. Wow, that is amazing. That is something that I have been looking for long time. The author really developed a successful web applcation and sold it to Yahoo. With those encouraging images, I determined to spend some time (1 year or 2 year, who knows) on learning Common Lisp. Maybe someday I will development my web application and turn into a great Lisp expert. In fact, this is the second time for me to get to study Lisp. The first time was a couple of years ago when I was fascinated by the famous book SICP but found later Scheme was so unbelievably immature for real life application. After reading some chapters of ANSI Common Lisp, I was pretty sure that is a great book full of detailed exploration of Common Lisp. Then I began to set up a web server in Common Lisp. After all, this should be the best way if you want to learn something. Demonstrations are always better than definations. As suggested by the book Practical Common Lisp (by the way, this is also a great book), I chose to install AllegroServe on some Common Lisp implementation. Then, from somewhere else, I learned that Hunchentoot seems to be better than AllegroServe. (I don't remember where and whom this word is from. So don't argue with me.) Ironically, you know what, I never could installed the two packages on any Common Lisp implementation. More annoyingly, I even don't know why. The machine always spit up a lot of jargon and lead me into a chaos. I've tried searching the internet and have not found anything. Could anybody who has successfully installed these packages in Linux tell me how you did it? Have you run into any trouble? How did you figured out what is wrong and fixed it? The more detailed, the more helpful.

  • Export multiple values from a single Combo Box? (Adobe Acrobat)

    - by metashockwave
    I'm trying to export 2 values from every single item from the combo box field. I have found two methods to insert items into a combo box: 1) insertItemAt http://www.verypdf.com/document/acrobat-forms-javascript/pg_0048.htm 2) setItems http://livedocs.adobe.com/acrobat_sdk/9/Acrobat9_HTMLHelp/wwhelp/wwhimpl/common/html/wwhelp.htm?context=Acrobat9_HTMLHelp&file=JS_API_AcroJS.88.748.html but neither method allows two parameters (im always get "missing ) after argument list" error from the Acrobat JavaScript Debugger) Does anyone know of a better solution for this problem? Thanks!

  • Android HttpsURLConnection and JSON for new GCM

    - by Ryan Gray
    I'm overhauling certain parts of my app to use the new GCM service to replace C2DM. I simply want to create the JSON request from a Java program for testing and then read the response. As of right now I can't find ANY formatting issues with my JSON request and the google server always return code 400, which indicates a problem with my JSON. http://developer.android.com/guide/google/gcm/gcm.html#server JSONObject obj = new JSONObject(); obj.put("collapse_key", "collapse key"); JSONObject data = new JSONObject(); data.put("info1", "info_1"); data.put("info2", "info 2"); data.put("info3", "info_3"); obj.put("data", data); JSONArray ids = new JSONArray(); ids.add(REG_ID); obj.put("registration_ids", ids); System.out.println(obj.toJSONString()); I print my request to the eclipse console to check it's formatting byte[] postData = obj.toJSONString().getBytes(); try{ URL url = new URL("https://android.googleapis.com/gcm/send"); HttpsURLConnection.setDefaultHostnameVerifier(new JServerHostnameVerifier()); HttpsURLConnection conn = (HttpsURLConnection) url.openConnection(); conn.setDoOutput(true); conn.setDoInput(true); conn.setUseCaches(false); conn.setRequestMethod("POST"); conn.setRequestProperty("Content-Type", "application/json"); conn.setRequestProperty("Authorization", "key=" + API_KEY); System.out.println(conn.toString()); OutputStream out = conn.getOutputStream(); // exception thrown right here. no InputStream to get InputStream in = conn.getInputStream(); byte[] response = null; out.write(postData); out.close(); in.read(response); JSONParser parser = new JSONParser(); String temp = new String(response); JSONObject temp1 = (JSONObject) parser.parse(temp); System.out.println(temp1.toJSONString()); int responseCode = conn.getResponseCode(); System.out.println(responseCode + ""); } catch(Exception e){ System.out.println("Exception thrown\n"+ e.getMessage()); } } I'm sure my API key is correct as that would result in error 401, so says the google documentation. This is my first time doing JSON but it's easy to understand because of its simplicity. Anyone have any ideas on why I always receive code 400? update: I've tested the google server example classes provided with gcm so the problem MUST be with my code.

  • Integration testing - Hibernate & DbUnit

    - by Marco
    Hi, I'm writing some integrations tests in JUnit. What happens here is that when i run all the tests together in a row (and not separately), the data persisted in the database always changes and the tests find unexpected data (inserted by the previous test) during their execution. I was thinking to use DbUnit, but i wonder if it resets the auto-increment index between each execution or not (because the tests also check the IDs of the persisted entities). Thanks M.

  • Sqlite / SQLAlchemy: how to enforce Foreign Keys?

    - by Nick Perkins
    The new version of SQLite has the ability to enforce Foreign Key constraints, but for the sake of backwards-compatibility, you have to turn it on for each database connection separately! sqlite> PRAGMA foreign_keys = ON; I am using SQLAlchemy -- how can I make sure this always gets turned on? What I have tried is this: engine = sqlalchemy.create_engine('sqlite:///:memory:', echo=True) engine.execute('pragma foreign_keys=on') ...but it is not working!...What am I missing?

  • CDNs and domains

    - by Martind
    Hi all! A lot of big websites (facebook etc) are settings up CDN's for their content. Now I notice, that these CDN's are not always on the original domain. Example: Facebook pictures are on "photos-a.ak.fbcdn.net" Why is that? Is there a performance-gain in not having lots of subdomains on the "primary" domain (facebook.com)

  • Perl vs Python: implementation of algorithms to deal with advanced data structures

    - by user350571
    I'm learning perl and everytime I search for perl stuff in the internet I get some random page with people saying that perl should die because code written in it looks like a lesson in steganography. Then they say that python is clean and stuff like that. Now, I know that those comparisons are always stupid and made by fellows that feel that languages are a extension of their boring personality so, let me ask instead: can you give me the implementation of a widely known algorithm to deal with a data structure like red-black trees in both languages so I can compare?

  • Can standard Sun javac do incremental compiling?

    - by calavera.info
    Recently I started to use Eclipse's java compiler, because it is significantly faster than standard javac. I was told that it's faster because it performs incremental compiling. But I'm still a bit unsure about this since I can't find any authoritative documentation about both - eclispse's and sun's - compilers "incremental feature". Is it true that Sun's compiler always compiles every source file and Eclipse's compiler compile only changed files and those that are affected by such a change?

  • Is this a situation where Qt Model/View architecture is not useful?

    - by csmithmaui
    Hi, I am writing a GUI based application where I read a string of values from serial port every few seconds and I need to display most of the values in some type graphical indicator(I was thinking of QprogressBar maybe) that displays the range and the value. Some of the other data that I am parsing from the string are the date and fault codes. Also, the data is hierarchical. I wanted to use the model/view architecture of Qt because I have been interested in MVC stuff for a while but have never quite wrapped my brain around how to implement it very well. As of now, I have subclassed QAbstractItemModel and in the model I read the serial port and wrap the items parsed from the string in a Tree data structure. I can view all of the data in a QtreeView with no issues. I have also began to subclass QAbstractItemView to build my custom view with all of the Graphical Indicators and such. This is where I am getting stuck. It seems to me that in order for me to design a view that knows how to display my custom model the view needs to know exactly how all of the data in the model is organized. Doesn't that defeat the purpose of Model/View? The QTreeView I tested the model with is basically just displaying the model as it is setup in the Tree structure but I don't want to do that because the data is not all of the same type. Is the type of data or the way you would like to present it to the user a determining factor in whether or not you should use this architecture? I always assumed it was just always better to design in an MVC style. It seems to me like it might have been better to just subclass QWidget and then read in from the serial port and update all of subwidgets(graphical indicators, labels, etc...) from the subclass. Essentially, do everything in one class. Does anybody understand this issue that can explain to me either what I am missing or why I shouldn't be doing it this way. As of now I am a little confused. Thanks so much for any help!

  • Making a lightbox support printing on web page

    - by bobo
    I know the idea is to use a separate stylesheet for printing that hides everything other than the lightbox when the user clicks the print button on the lightbox. It sounds easy but there are always some obstacles. So I would like to know if there is any working example that supports all major browsers. I searched in google and found many lightbox but none of them has a print button built-in.

  • Last matching symbol in Regex

    - by Menda
    I couldn't find a more descriptive title, but here there is an example: import re m = re.search(r"\((?P<remixer>.+) (Remix)\)", "Title (Menda Remix)") m.group("remixer") # returns 'Menda' OK m = re.search(r"\((?P<remixer>.+) (Remix)\)", "Title (Blabla) (Menda Remix)") m.group("remixer") # returns 'Blabla) (Menda' FAIL This regex finds the first parenthesis, and I would like to match the last parenthesis for always getting 'Menda'. I've made a workaround to this using extra functions, but I would like a cleaner and a more consistent way using the same regex. Thanks a lot guys.

  • How to secure an AJAX call from a facebook canvas application.

    - by user259349
    Reading this Ajax example, http://wiki.developers.facebook.com/index.php/FBJS/Examples/Ajax#Working_Example I found the following line. I'm not sure what to understand out of it, how do you "check the sig values per Platform spec"? "Note: For brevity's sake we are trusting $_POST['fb_sig_user'] without checking the full signature. This is unsafe as anyone could easily forge a user's action. Always be sure to either use the Facebook object which is supplied with the client libraries, or check the sig values per Platform spec"

  • Windows 7 SDK RC & Beta version

    - by Sarath
    Dear All, I've download Windows 7 SDK which was downloaded at the time of the beta release. Now I upgraded to RC and trying with some Direct2D samples. But I can't create the factory pointer using D2D1CreateFactory API. It's always returns NULL. Even the samples downloaded from MSDN is also not working well. There are some changes from Beta - RC Is this because of the version mismatch of SDK?
