  • Important Tips to make a user friendly Homepage

    - by Aditi
    We have done a lot of redesign work lately for many online businesses.. There are some basic things we want to stress into any web design which make it usable! Unfortunately most designers care about the graphic elements, clean code & navigation only. Most designers do not realize that a design they did could be a masterpiece to them but for a layman it could be tough to use. It is so very important to understand usability & call to action for any business and then implemented on their website Homepage. Showcase Offering The sole purpose of their websites needs to be mentioned on the homepage, what they are offering, why should one do business with them and why they are better than other competitors. Include a tag line under your logo that explicitly summarizes what the site or company does. Ease of Navigation Make it easier for your user to find what they are looking for, some archives, articles, services etc. A visible and easy to use Navigation allows just that. You may also want to feature some of the most visited content on the homepage itself. Search Form Let your users take advantage of a search form from your homepage, keep it visible enough so if they have trouble locating certain content using your navigation. The Search Bar will come handy in such situation. Especially if you have thousands and thousands of web pages. Liquid Layout There was a time when people used standard resolution, not any more. People have different screen sizes and most people now browse on handhelds. Try keeping liquid width so people can adjust as per their choice. First impression is last impression, leaving one through your perfect homepage can do wonders for your business.

  • YouTube: Tips by Bitwise Courses on NetBeans

    - by Geertjan
    I really like the potential of YouTube in providing a platform for short info clips that take not much time to produce and about as much time to consume. Huw Collingbourne's Bitwise Courses channel is full of exactly this kind of YouTube clip. Several of his YouTube clips are about or make use of NetBeans. The related Twitter account is @bitwisecourses and the homepage is bitwisecourses.com. Here's a great example, the latest YouTube clip created by Bitwise Courses. Very clear and simple explanation, on a specific and narrow topic, and very short and sweet. And very useful! Didn't know about this feature myself. Direct link to the movie: https://www.youtube.com/watch?v=b0fKT_hFQpU Here's to more of these, they're wonderful. More such YouTube clips are needed, short and precise, on very specific topics. And I'm very happy to promote them, as you can see.

  • Windows Defender Update KB915597 (Definition 1.135.415.0)? Killed My Live Discs

    - by user88311
    Here's my problem, for those willing to read for about 2 minutes here's the entire story, http://answers.microsoft.com/en-us/windows/forum/windows_vista-windows_update/bsod-after-windows-defender-update-kb915597/a4b5fca3-0274-47b4-97c4-61b34c4c4599, for those who want the short version here's what happened. After windows update automatically updated windows defender to kb915597, my computer starting getting bsods on shut down and start up and started experiencing problems withe the usb ports. So I decided to go to the microsoft answers site for help, I know that was probably my first mistake, so I followed their advice and they turned my computer into a large paper weight. Luckily I make physical backups of my c drive every few months and I have one from back in july, so I figured I'd boot up a ubuntu live disc, copy all my files from the past 2 months to a external drive and just copy the backup back to the c drive, that's where I ran into this problem. When I put in either a ubuntu or kubuntu disc, everything goes well, until it finishes the loading bar then when the OS would presumably start up, the computer resets, I've tried with ubuntu, kubuntu and gparted, and only gparted is able to get to the point where it starts up, but even then when I try to access the internet from it, the computer resets, and when I tried to copy the entire C drive partition to a blank external I wasn't able to. So I figured somehow maybe the C drive had something to do with it, so I unplugged the C drive so my computer was just a 2.8 ghz processor and 2 gigs of ram, should have had no problem starting a live disc but the problem still continues. After doing some googling around I've found whenever windows gets a update with the title KB915597 it's pretty much the kill switch for windows, I've tried contacting microsoft tech support and even managed to directly contact a software engineer but as soon as I mention KB915597 they all just blew me off. I hope anybody who reads this has any idea how to fix this, I'm going to attempt to install ubuntu or kubuntu to a external drive using the same computer and see what happens now.

  • Java collision detection and player movement: tips

    - by Loris
    I have read a short guide for game develompent (java, without external libraries). I'm facing with collision detection and player (and bullets) movements. Now i put the code. Most of it is taken from the guide (should i link this guide?). I'm just trying to expand and complete it. This is the class that take care of updates movements and firing mechanism (and collision detection): public class ArenaController { private Arena arena; /** selected cell for movement */ private float targetX, targetY; /** true if droid is moving */ private boolean moving = false; /** true if droid is shooting to enemy */ private boolean shooting = false; private DroidController droidController; public ArenaController(Arena arena) { this.arena = arena; this.droidController = new DroidController(arena); } public void update(float delta) { Droid droid = arena.getDroid(); //droid movements if (moving) { droidController.moveDroid(delta, targetX, targetY); //check if arrived if (droid.getX() == targetX && droid.getY() == targetY) moving = false; } //firing mechanism if(shooting) { //stop shot if there aren't bullets if(arena.getBullets().isEmpty()) { shooting = false; } for(int i = 0; i < arena.getBullets().size(); i++) { //current bullet Bullet bullet = arena.getBullets().get(i); System.out.println(bullet.getBounds()); //angle calculation double angle = Math.atan2(bullet.getEnemyY() - bullet.getY(), bullet.getEnemyX() - bullet.getX()); //increments x and y bullet.setX((float) (bullet.getX() + (Math.cos(angle) * bullet.getSpeed() * delta))); bullet.setY((float) (bullet.getY() + (Math.sin(angle) * bullet.getSpeed() * delta))); //collision with obstacles for(int j = 0; j < arena.getObstacles().size(); j++) { Obstacle obs = arena.getObstacles().get(j); if(bullet.getBounds().intersects(obs.getBounds())) { System.out.println("Collision detect!"); arena.removeBullet(bullet); } } //collisions with enemies for(int j = 0; j < arena.getEnemies().size(); j++) { Enemy ene = arena.getEnemies().get(j); if(bullet.getBounds().intersects(ene.getBounds())) { System.out.println("Collision detect!"); arena.removeBullet(bullet); } } } } } public boolean onClick(int x, int y) { //click on empty cell if(arena.getGrid()[(int)(y / Arena.TILE)][(int)(x / Arena.TILE)] == null) { //coordinates targetX = x / Arena.TILE; targetY = y / Arena.TILE; //enables movement moving = true; return true; } //click on enemy: fire if(arena.getGrid()[(int)(y / Arena.TILE)][(int)(x / Arena.TILE)] instanceof Enemy) { //coordinates float enemyX = x / Arena.TILE; float enemyY = y / Arena.TILE; //new bullet Bullet bullet = new Bullet(); //start coordinates bullet.setX(arena.getDroid().getX()); bullet.setY(arena.getDroid().getY()); //end coordinates (enemie) bullet.setEnemyX(enemyX); bullet.setEnemyY(enemyY); //adds bullet to arena arena.addBullet(bullet); //enables shooting shooting = true; return true; } return false; } As you can see for collision detection i'm trying to use Rectangle object. Droid example: import java.awt.geom.Rectangle2D; public class Droid { private float x; private float y; private float speed = 20f; private float rotation = 0f; private float damage = 2f; public static final int DIAMETER = 32; private Rectangle2D rectangle; public Droid() { rectangle = new Rectangle2D.Float(x, y, DIAMETER, DIAMETER); } public float getX() { return x; } public void setX(float x) { this.x = x; //rectangle update rectangle.setRect(x, y, DIAMETER, DIAMETER); } public float getY() { return y; } public void setY(float y) { this.y = y; //rectangle update rectangle.setRect(x, y, DIAMETER, DIAMETER); } public float getSpeed() { return speed; } public void setSpeed(float speed) { this.speed = speed; } public float getRotation() { return rotation; } public void setRotation(float rotation) { this.rotation = rotation; } public float getDamage() { return damage; } public void setDamage(float damage) { this.damage = damage; } public Rectangle2D getRectangle() { return rectangle; } } For now, if i start the application and i try to shot to an enemy, is immediately detected a collision and the bullet is removed! Can you help me with this? If the bullet hit an enemy or an obstacle in his way, it must disappear. Ps: i know that the movements of the bullets should be managed in another class. This code is temporary. update I realized what happens, but not why. With those for loops (which checks collisions) the movements of the bullets are instantaneous instead of gradual. In addition to this, if i add the collision detection to the Droid, the method intersects returns true ALWAYS while the droid is moving! public void moveDroid(float delta, float x, float y) { Droid droid = arena.getDroid(); int bearing = 1; if (droid.getX() > x) { bearing = -1; } if (droid.getX() != x) { droid.setX(droid.getX() + bearing * droid.getSpeed() * delta); //obstacles collision detection for(Obstacle obs : arena.getObstacles()) { if(obs.getRectangle().intersects(droid.getRectangle())) { System.out.println("Collision detected"); //ALWAYS HERE } } //controlla se è arrivato if ((droid.getX() < x && bearing == -1) || (droid.getX() > x && bearing == 1)) droid.setX(x); } bearing = 1; if (droid.getY() > y) { bearing = -1; } if (droid.getY() != y) { droid.setY(droid.getY() + bearing * droid.getSpeed() * delta); if ((droid.getY() < y && bearing == -1) || (droid.getY() > y && bearing == 1)) droid.setY(y); } }

  • Tips on googling for sugar

    - by Mikey
    I have a question up on SO I am a little embarassed I can't just google: http://stackoverflow.com/questions/13734664/groovy-variables-in-method-names-with-double-question-marks The problem is google seems to chuck any terms that are just punctuation, so queries like these: .findBy?? .and?? groovy '??' Are coming out the same as these: findBy and groovy I have had this problem before when I didn't know the name of the elvis operator, and countless other times (probably happened first time I saw an infix '%' mod too if I had to guess). Is there a resource for syntax sugar lookups? Some way to force google or a different search engine to not ignore my funky punctuation?

  • TFS work items tips

    - by Michael Freidgeim
    We started to use TFS to track requests using Work items. 1. Telerik's  TFS Work Item Manager (beta version for TFS 2010 is available) that could be interesting to use instead of standard VS2010, especially for someone who doesn’t want to have VS installed on their machine.(thanks to dimarzionist who pointed to the tool).See also TFS Project Dashboa 2.Visual Studio TFS work item attachments Tab I've found that Outlook emails can be dropped to TFS work item attachments. Just open TFS work item attachment tab and drag and drop Outlook email to it. Also you can copy any selected text and paste it to TFS work item attachments tab. The text will be saved as an attachment file.

  • Friday Tips #4

    - by Chris Kawalek
    It's time once again for our Friday tip. Our question today is about how to determine how much video RAM to allocate for your virtual machines in a VDI deployment: Question: How much video RAM do I really need on my VirtualBox VMs? Answer by John Renko, Consulting Developer, Oracle: The answer is in the VirtualBox admin guide but it's seldom followed correctly, usually resulting in excess unused RAM to be allocated. The formula for determining how much RAM to allocate is shown below for a 32 bit fullscreen 22" monitor supporting 1680x1050: bit depth / 8 x horizontal res x vertical res / 1024 / 1024 = MB RAM Which translates to: 32 bits / 8 x 1680 x 1050 / 1024 / 1024 = 6.7 MB If you wanted to support dual 22" monitors, you would need twice that, so 13.4 MB. Anything in excess of what is needed is readily allocated but not used and would be better suited for running more VMs! Thanks John, that tip should help folks squeeze a little more out of their VDI servers. And remember, if you have a question for us, use hash tag #AskOracleVirtualization on Twitter. We'll see you next week with another tip! -Chris

  • Tips for adapting Date table to Power View forecasting #powerview #powerbi

    - by Marco Russo (SQLBI)
    During the keynote of the PASS Business Analytics Conference, Amir Netz presented the new forecasting capabilities in Power View for Office 365. I immediately tried the new feature (which was immediately available, a welcome surprise in a Microsoft announcement for a new release) and I had several issues trying to use existing data models. The forecasting has a few requirements that are not compatible with the “best practices” commonly used for a calendar table until this announcement. For example, if you have a Year-Month-Day hierarchy and you want to display a line chart aggregating data at the month level, you use a column containing month and year as a string (e.g. May 2014) sorted by a numeric column (such as 201405). Such a column cannot be used in the x-axis of a line chart for forecasting, because you need a date or numeric column. There are also other requirements and I wrote the article Prepare Data for Power View Forecasting in Power BI on SQLBI, describing how to create columns that can be used with the new forecasting capabilities in Power View for Office 365.

  • Byte Size Tips: How to Stop OS X from Changing the Display Brightness Automatically

    - by The Geek
    After getting a new MacBook Air and deciding to try out OS X for a while, I started wondering why the battery would suddenly start dying really fast, but only when I was sitting at the kitchen table. That’s when I noticed the display brightness kept changing on its own… and realized the problem. OS X, just like your phone, and any modern device, tries to figure out the brightness of the room you’re in, and adjust the brightness of the screen. If you are over in Windows, it’s called “Adaptive” brightness, while your phone will just call it “Auto”. While this technology is great in theory, I don’t really need max brightness all the time, and I like to control it manually to make sure I’m getting the best battery life. Open up System Preferences, head to Displays. Then uncheck the Automatically adjust brightness setting.

    Have you ever accidentally deleted a photo on your camera, computer, USB drive, or anywhere else? What you might not know is that you can usually restore those pictures—even from your camera’s memory stick.

Luckily there’s another way to recover deleted files.

  • Project migration tips [closed]

    - by Shirish11
    I would like to know what all things are to be considered when your client asks for Project Migration to a different language / version. Migrating an existing project to a higher version is not going to be much of a trouble. Have to take care of some system files, some settings changes and if version specific components included then search for them to comply with the newer version. I understand why you need to migrate projects to newer versions mostly for overcoming the drawbacks of current version. But I have absolutely no idea how to go about language migration. Any help on this is appreciated . Moreover is language migration a healthy idea?
