  • Series On Embedded Development (Part 3) - Runtime Optionality

    - by Darryl Mocek
    What is runtime optionality? Runtime optionality means writing and packaging your code in such a way that all of the features are available at runtime, but aren't loaded and used if the feature isn't used. The code is separate, and you can even remove the code to save persistent storage if you know the feature will not be used. In native programming terms, it's splitting your application into separate shared libraries so you only have to load what you're using, which means it only impacts volatile memory when enabled at runtime. All the functionality is there, but if it's not used at runtime, it's not loaded. A good example of this in Java is JVMTI, Java's Virtual Machine Tool Interface. On smaller, embedded platforms, these libraries may not be there. If the libraries are not there, there's no effect on the runtime as long as you don't try to use the JVMTI features. There is a trade-off between size/performance and flexibility here. Putting code in separate libraries means loading that code will take longer and it will typically take up more persistent space. However, if the code is rarely used, you can save volatile memory by including it in a separate library. You can also use this method in Java by putting rarely-used code into one or more separate JAR's. Loading a JAR and parsing it takes CPU cycles and volatile memory. Putting all of your application's code into a single JAR means more processing for that JAR. Consider putting rarely-used code in a separate library/JAR.

  • Easy Server-Side Language

    - by Nizar
    Most of programming languages (Server-side languages for web development) needs a learning curve and requires some time to learn. However, I'm sure there is a difference between them. So, for example you can master the 'X' language in less time than the 'Y' language. I'm a beginner in web development, meaning that I just know HTML and CSS and now want to choose the right tool for building dynamic sites. What I'm looking for is a language that is easy to master in less time than other languages. So, is there a language that can suit my needs? If so, please let me know about what should I learn in it? (for example, which frameworks?, libraries?, IDEs?, databases?, etc). In the end, I don't want to regret my choice of the language and want to learn solid basics in it and in programming in general.

  • Booting Ubuntu shows only cursor, no desktop features

    - by jlkkljh
    I'm trying to install Ubuntu and have been trying since 2010 on my Win XP (2006-2008 I don't know which year's version exactly). I'm trying to get rid of XP and every time I install Ubuntu it doesn't work. I've tried all the options on the install list from Wubi and from inside the installer. I've tried a lot of different stuff and all it will load is a mouse cursor and a black screen. Please do help out with suggestions/advice. Thanks in advance.

  • External Full HD monitor and Virtual Desktop Size

    - by Stefan
    I have two FullHD monitors attached to my ATI graphics card [2]. The resolution of both of them is detected properly without any modifications to /etc/X11/xorg.conf. I can run both of them in clone mode. However, when I try to run them next to each other, I got the following error: The selected configuration for displays could not be applied. If tried to fix this according to [1]. My xorg.conf now looks like this: Section "Module" Load "glx" EndSection Section "Screen" Identifier "Default Screen" DefaultDepth 24 SubSection "Display" # The 1088 is the smallest multiple of 32 >= 1088 # see manpages Virtual 1920 1088 EndSubSection EndSection This does not seem to be parsed properly. After restarting X, I cannot set resolutions beyond 1600 or so any more. /var/log/Xorg.0.log gives: [ 15.676] (II) fglrx(0): Not using mode "1920x1080" (width too large for virtual size) [ 15.676] (II) fglrx(0): Not using mode "1680x1050" (width too large for virtual size) Are my modifications syntactically incorrect? According to the man page, it should be fine. Any ideas?

  • Computer Science Career Advice: Master's in Computer Science vs. Software Engineering?

    - by Everton
    Hello, I am a college student and I am majoring in Computer Science and Applied Mathematics. As I get closer to my senior year I have noticed that continuing my studies is the best choice right for me now. I see that several universities offer an Computer Science Master's Degree and an Software Engineering degree. What are their pros and cons? I feel that while the Computer Science master's degree seems a little too broad the Software Engineering is too restrictive. I did not decide yet between an career of Software development or research ( algorithm development among other things ). Any advice would be greatly apreciated!

  • Beginner Scoring program button development in Java [migrated]

    - by A.G.
    I'm trying to add a "green team" to an example scoring GUI I found online. For some reason, the code compiles, but it runs with only the original two teams. I've tried playing around with the sizes/locations somewhat clumsily, and since no change was observed with these modications (NO change at ALL), I admit that I must be missing some necessary property or something. Any help? Here's the code: import javax.swing.*; import java.awt.Color; import java.awt.event.ActionListener; import java.awt.event.ActionEvent; public class ButtonDemo_Extended3 implements ActionListener{ // Definition of global values and items that are part of the GUI. int redScoreAmount = 0; int blueScoreAmount = 0; int greenScoreAmount = 0; JPanel titlePanel, scorePanel, buttonPanel; JLabel redLabel, blueLabel,greenLabel, redScore, blueScore, greenScore; JButton redButton, blueButton, greenButton,resetButton; public JPanel createContentPane (){ // We create a bottom JPanel to place everything on. JPanel totalGUI = new JPanel(); totalGUI.setLayout(null); // Creation of a Panel to contain the title labels titlePanel = new JPanel(); titlePanel.setLayout(null); titlePanel.setLocation(0, 0); titlePanel.setSize(500, 500); totalGUI.add(titlePanel); redLabel = new JLabel("Red Team"); redLabel.setLocation(300, 0); redLabel.setSize(100, 30); redLabel.setHorizontalAlignment(0); redLabel.setForeground(Color.red); titlePanel.add(redLabel); blueLabel = new JLabel("Blue Team"); blueLabel.setLocation(900, 0); blueLabel.setSize(100, 30); blueLabel.setHorizontalAlignment(0); blueLabel.setForeground(Color.blue); titlePanel.add(blueLabel); greenLabel = new JLabel("Green Team"); greenLabel.setLocation(600, 0); greenLabel.setSize(100, 30); greenLabel.setHorizontalAlignment(0); greenLabel.setForeground(Color.green); titlePanel.add(greenLabel); // Creation of a Panel to contain the score labels. scorePanel = new JPanel(); scorePanel.setLayout(null); scorePanel.setLocation(10, 40); scorePanel.setSize(500, 30); totalGUI.add(scorePanel); redScore = new JLabel(""+redScoreAmount); redScore.setLocation(0, 0); redScore.setSize(40, 30); redScore.setHorizontalAlignment(0); scorePanel.add(redScore); greenScore = new JLabel(""+greenScoreAmount); greenScore.setLocation(60, 0); greenScore.setSize(40, 30); greenScore.setHorizontalAlignment(0); scorePanel.add(greenScore); blueScore = new JLabel(""+blueScoreAmount); blueScore.setLocation(130, 0); blueScore.setSize(40, 30); blueScore.setHorizontalAlignment(0); scorePanel.add(blueScore); // Creation of a Panel to contain all the JButtons. buttonPanel = new JPanel(); buttonPanel.setLayout(null); buttonPanel.setLocation(10, 80); buttonPanel.setSize(2600, 70); totalGUI.add(buttonPanel); // We create a button and manipulate it using the syntax we have // used before. Now each button has an ActionListener which posts // its action out when the button is pressed. redButton = new JButton("Red Score!"); redButton.setLocation(0, 0); redButton.setSize(30, 30); redButton.addActionListener(this); buttonPanel.add(redButton); blueButton = new JButton("Blue Score!"); blueButton.setLocation(150, 0); blueButton.setSize(30, 30); blueButton.addActionListener(this); buttonPanel.add(blueButton); greenButton = new JButton("Green Score!"); greenButton.setLocation(250, 0); greenButton.setSize(30, 30); greenButton.addActionListener(this); buttonPanel.add(greenButton); resetButton = new JButton("Reset Score"); resetButton.setLocation(0, 100); resetButton.setSize(50, 30); resetButton.addActionListener(this); buttonPanel.add(resetButton); totalGUI.setOpaque(true); return totalGUI; } // This is the new ActionPerformed Method. // It catches any events with an ActionListener attached. // Using an if statement, we can determine which button was pressed // and change the appropriate values in our GUI. public void actionPerformed(ActionEvent e) { if(e.getSource() == redButton) { redScoreAmount = redScoreAmount + 1; redScore.setText(""+redScoreAmount); } else if(e.getSource() == blueButton) { blueScoreAmount = blueScoreAmount + 1; blueScore.setText(""+blueScoreAmount); } else if(e.getSource() == greenButton) { greenScoreAmount = greenScoreAmount + 1; greenScore.setText(""+greenScoreAmount); } else if(e.getSource() == resetButton) { redScoreAmount = 0; blueScoreAmount = 0; greenScoreAmount = 0; redScore.setText(""+redScoreAmount); blueScore.setText(""+blueScoreAmount); greenScore.setText(""+greenScoreAmount); } } private static void createAndShowGUI() { JFrame.setDefaultLookAndFeelDecorated(true); JFrame frame = new JFrame("[=] JButton Scores!

  • Desktop background will not load after performing aticonfig --adapter=all --ovt=opengl

    - by user1571959
    I am trying to get Eagle to work on ubuntu 14.04 LTS. When I run Eagle and open a schematic the display is not refreshing/redrawing correctly. One solution that I found was to install the flgrx drivers and do the aticonfig command to use opengl... So I did and rebooted. Now when I turn on my laptop I get all the way to the login screen, login, and then nothing happens, it just goes to the background image with no icons or anything... I tried deleting and copying the original xorg.conf file and no results... What do I do other than reinstalling Ubuntu? is there anyway to force the original driver?

  • Pantheon Not Completely Installed?

    - by Simon
    I have just installed the pantheon shell today, and I have not found any help with this yet. I am not just a random noob, i use a bunch of other shells and i also have a few development applications on my copy of ubuntu. But ever since ive opened up pantheon, i cannot find settings or this thing called the launchpad. (if the launchpad is the app drawer up in the upper left corner, or if its the dock. i have it, if thats not what launchpad is, then i cant access it.) I can only change my wallpaper by going back to unity, gnome, or KDE. There is a system settings in the power menu (upper right), but it only has Language Support, Ubuntu One, Additional Drivers, And Printing. I can still access the full ubuntu settings in GNOME of Unity. But thats it. I installed in the terminal, uninstalled, and reinstalled using the software center. Please Help Me If Any Of You Can! Thanks!!!
