why doesn’t graphics on ios lag as much? apparently, it’s because when you put the finger on the screen, it stops every process, except of a couple of important system services. even if you run a browser, and you put finger on screen, it stops unless you raise the finger.

android, on the contrary, tries to divide resources between processes.

this is why we often notice lags on android, and this is why ios seems to work smoothly. we cannot say - faster. it’s not faster, because other processes don’t even work for some time. it’s responsive, and looks faster to the user.

well, at least, this is why it’s often happens, when android user cannot call, or answer the call, while the same situation is not very much common in case of ios.

By analysing signalling messages exchanged during a WhatsApp call using an Android device, the researchers were able to closely examine the authentication process of WhatsApp clients; discover what codec WhatsApp is using for voice media streams (Opus at 8 or 16 kHz sampling rates); understand how relay servers are announced and the relay election mechanism; and understand how clients announce their endpoint addresses for media streams.

A paper about the study, entitled WhatsApp Network Forensics: Decrypting and Understanding WhatsApp Call Signaling Messages, was published in the scholarly journal Digital Investigation. The article was co-authored by F. Karpisek of Brno University of Technology in the Czech Republic, and Ibrahim Baggili and Frank Breitinger, co-directors of the Cyber Forensics Research & Education Group at the University of New Haven.

Today I’ve got a warning that there is shortage of space on SD card. Was surprised, started to check. It turned out there is a file in the root, called “stream.wav”, and information is actively being written to it. I’ve listened the content - every event, talks, recording from the microphone for last 2 days. Checked my tablet - the same shit. As I am using CyanogenMod on my tablet, I have found out the reason pretty soon(see screenshot). Spying app is Yandex.Navigator. Now I’ll check logs of my home router, happily I have FreeBSD there, and I log everything, will check where my information went. Block this app or better uninstall it for good!

Yandex commented that it’s a bug.


Yes I believe it’s a bug indeed. We weren’t supposed to know that it spies, and it wasn’t supposed to eat such amount of space probably to remain unnoticed. Yandex will fix the bug and it’ll be harder to notice that it’s apps are spying after people. (:

one of the main technologies that keeps java afloat, and reasons why java is used today, is android. (so oracle needs to review their patent claims and just let people use java)

and if oracle wants java to be a player in internet of things business, they need to wish android success in that niche instead of suing google constantly.
