Recommended browser for course?

edited Apr 28, 2017 7:37PM in Java Puzzle Ball

Hi, I've just completed the first lesson (thank you for creating this course)

While going through the content I was not seeing green ticks as I completed the various parts of the lesson. Once I'd done all the tasks, the progress tab showed only about half of the items as completed.  I managed to get everything to show 100% by going in and out several times for all the unticked activities but it took some time.

Is there a recommeneded browser I should be using to follow this course?  (I'm running Firefox 53.0 32-bit)



Also, when trying to run any of the projects supplied for the course in netbeans, I get an error appear- "one or more project resources could not be found".  The fix was simple enough but thought I'd highlight it in case you wanted to put it in the FAQ...

click "resolve problems"

problem: "JDK_1.8" platform could not be found

click "resolve"

under "use an existing Java platform", choose the installed JDK, in my case named "JDK 1.8"

(only weirdness on my install is I installed to my D-drive, perhaps this confused things?)

    Hi Simon,

    Does this issue occur with both videos and non-videos?  To get the progress bar to increase for watching a video, I've noticed I have to watch a video to the very end.  So a good workaround is to open a video, skip to the last few seconds, and watch until it ends.  If the green tick isn't appearing with non-videos, you might have discovered a bug.  I don't believe there's a recommend browser, but if the bug does exist, I'll let the dev team know and they can investigate

    Thanks for the "JDK_1.8 platform could not be found" tip!  I haven't been able to reproduce the bug, but I'll add the solution to the FAQ.

    Hi Nick

    thanks for your reply, the issue initially occured with both types but a re-click of the non-video links seemed to resolve the issue for them.  Whereas the video links took 5-6 attempts for me to get them to show as viewed.

    I thought perhaps it might be due to a slow wifi connection.  When I was doing the first few tasks my laptop was on wifi and struggling to load pages and play videos, so I switched to ethernet cable and things improved but perhaps it confused the site, either way not a huge problem but thought I'd let you know 

    As for the JDK error, very weird one.  Install was a standard (next, next, next) from the link posted on the course instructions, only difference being I changed the destination for the JDK, netbeans, etc to my D-drive
