Not sure if someone else noticed it, but some charts in Apple’s Stocks application got broken recently. Looks like last data point is always 0.0000, which causes charts to get distorted and unfortunately useless. Issue seems to affect currency exchange rates, but only for some pairs and only for periods >= 1m.

For example GBP/EUR:



Other problematic currency pairs I identified: GBP/PLN, CHF/PLN, EUR/PLN.



Few days ago a new Java vulnerability has been discovered that affects all versions of Java 7 on most browsers. Luckily Oracle addressed it quickly by releasing an update. Since I previously had JDK 1.7.0_04 installed, I had to manually switch to use latest version by going to Applications > Utilities > Java Preferences and changing active version in the drop-down.

I wanted to remove the old version from my Mac, since it was unlikely I’d ever use it again. Unfortunately Oracle help page I found did not offer the solution. Luckily this turned out to be rather easy – all you need to do is go to Mac HD / Library / Java / JavaVirtualMachines and remove VM file that you no longer need (jdk1.7.0.jdk in my case).

Hope that helps.

Today I launched iCal and noticed that all my entries were duplicated. Removing unnecessary copies would be so time consuming it’s not even funny. After I opened Calendars List, it showed two sets of calendars – On My Mac and iCloud. Unchecking every calendar in one of them, even thought seemed to help, was not a real solution. Luckily real fix is equally simple. It worked for me, hopefully will help someone:

Quit iCal, go to System Preferences and navigate to iCloud. Uncheck Calendars, confirm and then check Calendars again. Confirm again if needed and launch iCal. You should only see a list of iCloud calendars and no duplicates!
