I find that the transition is not so neat - in the animation below, you can see that the rectangular imageview seem to reduce in size until it matches the size of the circle. The

For WhatsApp it's "com.whatsapp" . So: Cursor c = getContentResolver (). query ( RawContacts . CONTENT_URI , new String [] { RawContacts . CONTACT_ID , RawContacts . DISPLAY_NAME_PRIMARY }, RawContacts . ACCOUNT_TYPE + "= ?" , new String [] { "com.whatsapp" }, null );

问题 On Ubuntu, the maximum number of sockets which can be opened seems to be governed from following: $ cat /proc/sys/net/ipv4/tcp_max_orphans 262144 As per one of the presentations by Rick Reed (from WhatsApp), these guys took it up to 2 million concurrent connections on a "single server" using FreeBSD and ErLang. My understanding is that we will always need some support from the kernel. And yes, looks like the tweaked the FreeBSD to have this capability: hw.machine: amd64 hw.model: Intel(R)
