Google - Convert Google Maps starred places into a My Map

noreply@blogger.com (Anonymous) — Tue, 23 Aug 2016 19:27:00 +0000

Found this on Google Maps forum:

You can export them using Google Takeout
https://www.google.com/settings/takeout
Export them from "Google Maps (My Places)", not from "Bookmarks".
They will be downloaded as a GeoJSON file.
You can use this site to convert your file to KML GeoJSON
http://nearby.org.uk/convert-saved-places.php
Once you download the KML file you can import it into your custom map
This help center article explains how to do it.

Virtual functions performance cost

noreply@blogger.com (Anonymous) — Fri, 04 Apr 2008 17:48:00 +0000

From Efficient C++ Performance Programming Techniques:

Virtual functions seem to inflict a performance cost in several ways:
The vptr must be initialized in the constructor.
A virtual function is invoked via pointer indirection. We must fetch the pointer to the function table and then access the correct function offset.
Inlining is a compile-time decision. The compiler cannot inline virtual functions whose resolution takes place at run-time.

Ubuntu - core dump

noreply@blogger.com (Anonymous) — Sun, 28 Oct 2007 20:02:00 +0000

From https://answers.launchpad.net/ubuntu/+question/10616

It appears that resource limits (which include the maximum size of a core dump file) are set by PAM on login. The settings for these limits are in /etc/security/limits.conf, which on my system (which is unmodified) is comments only. A quick look at the source code suggests that the default core dump limit is 0 (zero), which means no dump at all is created (even though the message suggests otherwise).

In summary: edit /etc/security/limits.conf, set the core limit to be non-zero (measured in kilobytes), and log in again.

I hope that works!

Put this in your .bashrc:
