Why won't Java Applets run in my web browser?
Java applets are small programs that are typically designed to run in a Web browser. Common applets include math programs, 3D model viewers, and various types of games. Since these programs are written in Java, they require a Java compiler, or Java Virtual Machine (JVM) to run.Most computer systems today come with Java pre-installed, which includes support for Java applets. However, some applets may contain code that requires an updated version of Java. This means they won't run on computers with older Java installations. Also, if Java is not installed correctly, some Web browsers may not recognize Java applets.The remedy for both of these problems is to install the latest version of Java. Fortunately, Java is available as a free download. Windows and Linux users can get the latest version of Java at Sun Microsystems' Java Downloads page. Since Java is installed as part of Mac OS X, Mac users can update their Java installation using the Mac OS X "Software Update" feature.After installing the latest version of Java, you may be asked to restart your computer. Once your computer restarts, open your Web browser and try loading the Java applet that wouldn't open before. It should be recognized by your browser and will run using the newly installed Java Virtual Machine.
If I haven't updated my Mac OSX in 3 years and I finally update it, will I lose everything I have saved on my Mac?
No. Mac updates don’t erase existing data.You should of course make a good backup before performing an update, since there’s always a chance something could go wrong. Time Machine works well for this; you’ll need an external drive at least as large as your existing drive. You could also use some form of online backup, but that can take a long time. “To always move forward we must always back up.”After that, run the update. Some updates take 30 minutes, some take longer.
If you like Java, why do you like it?
Type Safety - Java is strongly typed. It forces you to precise. You have to define the type of the variables you are using - there is no magic involved. What at first seems hard for beginner, will make life much easier for you - there won’t be any hidden surprise. An apple is an apple and stays an apple. An apple will never be a pear.Object Orientation - Java is an object oriented language. This allows you to model, design your code in a way that closely relates to the real world. You can talk to your customer about your code “There is a Tree of apples and one apple is falling down” - and without any programming knowledge, the customer will understand what you are talking about.Performance - Java has an awesome performance, and with newer compilers and JVMs is getting better every year.Garbage Collection - Java was my first programming language, so to me it totally made sense that I just created objects and never had to care about memory allocation and de-allocation - It felt so intuitive, so normal, I didn’t realize how cool it was - until I started learning some C. You have to do it all on your own - get some free memory, use it, make sure you free it after you’re done, or you will soon run into problems - that is a big challenge on its own! Not much time for the actual problem you wanted to solve in the first place.Libraries - Java is massive. There is code for almost anything you could wish for, either natively in the JDK, or available as open source.Jobs - I never had to look hard for a job - for example after university, I got more offers than I was willing to take interviews. I took about 10, and then picked the best option out of the 10.
How do I know if my Mac has a virus?
Macs can get viruses and do get viruses. But there are not very many and they are not as serious as the ones that are on Windows. Some people will tell you this is because the Mac doesn't have the the large installed base of windows. But this is not the reason why. The reason why there are less viruses in the MacOSX today is because Apple has really good mechanisms for patching the MacOSX quickly and easily when a virus does appear and because down deep MacOSX is based on a very secure architecture called UNIX. Out-of-the-box Mac OSX does not enable root user account (although you can over ride this) and is really good about requiring a username and a password in order to do much of anything to the operating system itself. This means that the virus does not have access to a lot of the lower level things that can do a lot of damage on the vast majority of macs. Because of this a lot of virus writers don't even bother to write things that work on the MacOS. Windows doesn't share these features and is therefore much less secure than the Mac which makes it a major target for virus writers who get thier jollies doing evil things to computers. Window out of the box is not as secure or well written. Microsoft has traditionally been much slower about patching it's systems and a lot of the windows install base are running out of date versions of the OS. You have to do a lot of work to secure a windows system and a huge percentage of the user base doesn't bother to do the work. Because of this millions and millions of Windows machines are open to viral attacks. This is led to a situation where the general public has the false belief that Macs don't get viruses. So while you can't say that the MacOS doesn't have viruses you can say that the Mac OS has very few of them that you need to be afraid of and they get felt with quickly.
Stuff is being downloaded onto my computer without my knowledge/authorization?
Take these steps to remove the vast majority of malware. 1. Run rkill, no need to install, just download to the desktop, and double click the icon to launch it. A log will display upon successful completion, close it, and move to the next step. If your security software tries to prevent rkill from running, allow it, it's safe. http://www.bleepingcomputer.com/download/rkill/ 2. After rkill has run successfully, run a FULL scan with MBAM, it's free: http://www.techspot.com/downloads/4716-malwarebytes-anti-malware.html Delete everything MBAM finds, and restart your computer when prompted. 3. If your subscription to norton has run out, then uninstall it, using the norton removal tool, or get another subscription, update it, and run a FULL scan with it. If you want better internet security than norton, uninstall norton: https://www-secure.symantec.com/norton-support/jsp/help-solutions.jsp?docid=kb20080710133834EN_EndUserProfile_en_us&product=home&pvid=f-home&version=1&lg=en&ct=us Then install Comodo internet security, it's free, and better than norton: http://www.comodo.com/home/internet-security/free-internet-security.php Run a FULL scan with it.

How do I get rid of this "Java run time" update window that keeps popping up on my MacBook once and for all?
To remove java from your MacBook, open up your Terminal (it’s in /Applications/Utilities) and then copy/paste the following commands:sudo rm -fr /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin sudo rm -fr /Library/PreferencePanes/JavaControlPanel.prefPane sudo rm -fr ~/Library/Application\ Support/Oracle/Javaecho "done"That last ‘echo’ command doesn’t do anything important—it just prints the word ‘done’ to your screen. But because some copy/pastes into Terminal don’t automatically issue the final carriage return, I’ve found that adding that additional line insures that the important parts before that actually get executed.You will need to enter your administrator password into your Terminal when prompted because of the ‘sudo’ command. As you type in your password, nothing is shown on the screen. That is normal. Just type it in without seeing any feedback, then hit Return when you’ve finished typing in the password.Also, if you’ve never issued ‘sudo’ in your Terminal before, you will get a warning about it. That’s normal for the first-ever use of sudo by any user.
What is the best GUI written in VB (any software package) that you know of? Most creative look and feel? (InVB
I'm considering whether to re-write or refresh an older software package that extensively used VB for its client side application. The Old VB client looks very 1998. What can VB do now as far as look and feel, or interface is concerned? Can it produce something very webby, like yahoo maps? Can it approach Mac-like fades and disolves? What are some good examples that can be seen? Related question is, what toolsets are available to update the older clients with a new look and feel? Any guidance would be greatly appreciated. Thanks in advance!
Which are the popular applications built on Java?
