  • Want to learn/dive into Java Web Development—where to start?

    - by ernesto che
    Hi folks, I want to dive into Java Web Development, but I don’t know where to start because I am overwhelmed with Frameworks, JSRs, modules and the like. Coming from a PHP and Ruby (on Rails) background, it may seem awkward to go the other way ’round—still there are a lot of places where Java is (and probably will be) prevalent. I know basic Java concepts, syntax and OOP, and I have done (too much) nonsense in existing projects in JSP. I am already using SVN and GIT, but like coding PHP and Ruby mostly via VIM, i’ve also done versioning from the command line. But this time I want to learn to build a new project from the ground up, in a more, let’s say, academic way (instead of the hackery to date). Looking at e. g. Eclipse frightens me. Then there is Struts, Spring, JPA, Hibernate, Seam, just to throw in some buzzwords, that I cannot put into clear relation to each other. Can you point me to some tutorials or books that could help me? What are the technologies you absolutely have to know, the JSRs that are widely implemented in the industry? Or, if you are an employer: What does a “Junior Java Web developer” have to know? Thanks for your suggestions!

  • Dofollow or Nofollow trackbacks?

    - by Ernesto Marrero
    Trackbacs Dofollow? ¿yes or not? Authoritative sources, Pleasse Thinking about SEO, is it better that they are dofollow trackback or nofollow trackbacks? When I write a post on my blog, I automatically send trackback to my site from http://bitacoras.com. The above link is dofollow. Is it advisable to give relevance to this link in also handling dofollow link? For example any domain. on the homepage has pagerank 3. This site has a pagerank 0 of the internal page that I send trackbacks to. Is it convenient to send dofollow links to that page to increase the pagerank? Will they increase my pagerank if I perform this operation?

  • How to get Bus and Device relationship for a /dev/ttyUSB

    - by Ernesto Campohermoso
    I need to write an script for restart USB dongles. I have all tools but I can't link my /dev/ttyUSBx to physical BUS and DEVICE. An issue is that I have three dongles with the same id vendor and id product. If I do lsusb the output is: Bus 001 Device 004: ID 12d1:1003 Huawei Technologies Co., Ltd. E220 HSDPA Modem / E270 HSDPA/HSUPA Modem Bus 001 Device 006: ID 12d1:1003 Huawei Technologies Co., Ltd. E220 HSDPA Modem / E270 HSDPA/HSUPA Modem Bus 001 Device 007: ID 12d1:1003 Huawei Technologies Co., Ltd. E220 HSDPA Modem / E270 HSDPA/HSUPA Modem Bus 001 Device 002: ID 80ee:0021 Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub And I have attached it to: /dev/ttyUSB0 /dev/ttyUSB3 /dev/ttyUSB5 But I want to know which device is related with which Bus Device. By example I need to get the following: /dev/ttyUSB0 -> Bus 001 Device 006 /dev/ttyUSB3 -> Bus 001 Device 004 /dev/ttyUSB5 -> Bus 001 Device 007 I'm using Ubuntu Server 10.04 and I tested the tools: lsusb hal lsmod But I can't get the relationship.

    - by Ernesto Rojo Jr
    I just updated to VS2010 from 2008. Now i'm getting an exception from vector iterators. Here's a code snippet that shows the issue. std::vector<CButton*> m_objButtons; for (std::vector<CButton*>::iterator i = m_objButtons.begin(); i != m_objButtons.end(); ++i) {} I get the debug message "vector iterators incompatible". Anyone run into this too?

  • Checking to see if a number is evenly divisible by other numbers with recursion in Python

    - by Ernesto
    At the risk of receiving negative votes, I will preface this by saying this is a midterm problem for a programming class. However, I have already submitted the code and passed the question. I changed the name of the function(s) so that someone can't immediately do a search and find the correct code, as that is not my purpose. I am actually trying to figure out what is actually MORE CORRECT from two pieces that I wrote. The problem tells us that a certain fast food place sells bite-sized pieces of chicken in packs of 6, 9, and 20. It wants us to create a function that will tell if a given number of bite-sized piece of chicken can be obtained by buying different packs. For example, 15 can be bought, because 6 + 9 is 15, but 16 cannot be bought, because no combination of the packs will equal 15. The code I submitted and was "correct" on, was: def isDivisible(n): """ n is an int Returns True if some integer combination of 6, 9 and 20 equals n Otherwise returns False. """ a, b, c = 20, 9, 6 if n == 0: return True elif n < 0: return False elif isDivisible(n - a) or isDivisible(n - b) or isDivisible(n - c): return True else: return False However, I got to thinking, if the initial number is 0, it will return True. Would an initial number of 0 be considered "buying that amount using 6, 9, and/or 20"? I cannot view the test cases the grader used, so I don't know if the grader checked 0 as a test case and decided that True was an acceptable answer or not. I also can't just enter the new code, because it is a midterm. I decided to create a second piece of code that would handle an initial case of 0, and assuming 0 is actually False: def isDivisible(n): """ n is an int Returns True if some integer combination of 6, 9 and 20 equals n Otherwise returns False. """ a, b, c = 20, 9, 6 if n == 0: return False else: def helperDivisible(n): if n == 0: return True elif n < 0: return False elif helperDivisible(n - a) or helperDivisible(n - b) or helperDivisible(n - c): return True else: return False return helperDivisible(n) As you can see, my second function had to use a "helper" function in order to work. My overall question, though, is which function do you think would provide the correct answer, if the grader had tested for 0 as an initial input?

  • Create a Task list, with tasks without executing

    - by Ernesto Araya Eguren
    I have an async method private async Task DoSomething(CancellationToken token) a list of Tasks private List<Task> workers = new List<Task>(); and I have to create N threads that runs that method public void CreateThreads(int n) { tokenSource = new CancellationTokenSource(); token = tokenSource.Token; for (int i = 0; i < n; i++) { workers.Add(DoSomething(token)); } } but the problem is that those have to run at a given time public async Task StartAllWorkers() { if (0 < workers.Count) { try { while (0 < workers.Count) { Task finishedWorker = await Task.WhenAny(workers.ToArray()); workers.Remove(finishedWorker); finishedWorker.Dispose(); } if (workers.Count == 0) { tokenSource = null; } } catch (OperationCanceledException) { throw; } } } but actually they run when i call the CreateThreads Method (before the StartAllWorkers). I searched for keywords and problems like mine but couldn't find anything about stopping the task from running. I've tried a lot of different aproaches but anything that could solve my problem entirely. For example, moving the code from DoSomething into a workers.Add(new Task(async () => { }, token)); would run the StartAllWorkers(), but the threads will never actually start. There is another method for calling the tokenSource.Cancel().

  • Creating a QMainWindow from Java using JNI

    - by ebasconp
    Hi everybody: I'm trying to create a Qt main windows from Java using JNI directly and I got a threading error. My code looks like this: Test class: public class Test { public static void main(String... args) { System.out.println(System.getProperty("java.library.path")); TestWindow f = new TestWindow(); f.show(); } } TestWindow class: public class TestWindow { static { System.loadLibrary("mylib"); } public native void show(); } C++ impl: void JNICALL Java_testpackage_TestWindow_show (JNIEnv *, jobject) { int c = 0; char** a = NULL; QApplication* app = new QApplication(c, a); QMainWindow* mw = new QMainWindow(); mw->setWindowTitle("Hello"); mw->setGeometry(150, 150, 400, 300); mw->show(); QApplication::exec(); } and I get my window painted but frozen (it does not receive any event) and the following error message when instantiating the QMainWindow object: QCoreApplication::sendPostedEvents: Cannot send posted events for objects in another thread I know all the UI operations must done in the UI thread but in my example I created the QApplication in the only thread I have running, so, everything should work properly. I did some tests executing the code of my "show" method from a QMetaObject::invokeMethod stuff using Qt::QueuedConnection but nothing works properly. I know I could use Jambi... but I know that it could be done natively too and that is what I want to do :) Any ideas on this? Thanks in advance! Ernesto
