How to get Eclipse working on OS X 10.10 Yosemite

After downloading Eclipse (Luna 4.4.2) on Max OS X 10.10.3 Yosemite it failed to start-up. It gave the highly misleading error message To open “eclipse” you need to install the legacy Java SE 6 runtime.

OSX Eclipse asking for Java 6 to be installed.

Installing Java 6 isn’t a good idea. It’s out of support and now has a number of serious security issues. Common sense says there has to be a better solution.

Try going to the OS X Command line and enter the command java -version

In my case then displayed the message, To use the “java” command-line tool you need to install a JDK.

Note that it’s asking you to install a JDK. I knew I had the latest version of Java runtime (JRE) installed so had expected the Java -version command to display Java 8. Clicking on More info will take you through to the Oracle Java download site.

From here download the Mac OS X 64 bit JDK and then when the download has completed click on the dmg file in the download loads directory and follow the install instructions.

Once complete try the Java -version command again from the command line to prove the install has been successful.  In my case this came back with:

java -version

java version “1.8.0_45″

Java(TM) SE Runtime Environment (build 1.8.0_45-b14)

Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)

Now clicking on the Eclipse icon will successfully launch Eclipse.

How can I see what is trending in the iPhone Twitter App?

It’s often useful to keep an eye on what’s trending on Twitter but in the latest versions of the iPhone Twitter App it’s not immediately obvious where to find what’s trending.

It’s actually really simple when you know.

How to see whats trending in the Twitter App.

At the top of your timeline screen just under where is says Home you’ll see 3 little dots. This is an iPhone App standard way to say that there’s more to see if you swipe left. The trick is to swipe left as shown by the arrow on one of the tweets not on the header itself.

Once you’ve swiped left you’ll see the ‘What’s Trending’ screen:

You can then click on one of the hashtags to see what people are saying or return to your hime page by swiping right or just press the timelines button.
