GCC 7.1 is out

GCC 7.1 was released on May 2.

I tried it out and recompiled all my Ada related builds, finally I got a stable GPS that does not crash after opening a project file. It still crashed on me, maybe I should revert to an older version?

I have updated my build scripts ada-4-slackware on gitHub. There is still some problems with ASIS 2016, some API changed for the new compiler, will update the build script once got time.

A strange 3D building from Google earth

As Google just release a new version of Google earth, I tried it on my phone with "I'm feeling Lucky" button ^_^, it lead me to the "Montparnasse Tower", the 3D view is strange on the north-west facing, there is a swirling hole in the upper part of the building.

You could find it by searching "Montparnasse Tower" or go to this link Montparnasse Tower from Chrome.

iPad not charging and a simple solution

I got an iPad that is not charging, connect the power cable does not show any indication of charging, and power keeps draining.  Search around the web, it seems it is quite common.

I follow a few advises from the search:

1. Use compressed air to clean the input socket.
2. Force a restart.
3. Switch outlets or ports.
4. Switch cables.
5. Restore in iTunes

None of it working.  But, during test of stage 5, I actually got the iPad charged in recovery mode. And it only works in recovery mode when connecting to a computer, it won't work when charging from an power adapter.

That makes me thinking, why could it be charged under recovery mode but not normal operation? Hardware seems working, is it a software issue? But I have fully restored the iPad with no success. I search the web again, and found this one: Simple solution if your iPhone or iPad is not charging. It seems simple, and I took a toothpick and start picking the input socket, it does not have lots of lint coming out, just a little bit of dirt. And it works!
