How to speed up Android Emulator on uX system - UPDATED

If you are developing for Android, you probably have already abandoned the emulator that comes with Android SDK, and are testing and debugging on a real device. I cannot blame you - the emulator is awfully slow. Well I have good news for you - you can speed it up, if you are using uX system (Unix like - Linux, Mac OS X, BSD). The trick is very simple - and I suppose some of you have already activated it - mount /tmp folder into memory.

I had encounter several times that when using MaxOS X Lion, when I try to unlock system preferences (usually for setting user access, privacy settings, etc) - the unlock icon does not respond - does nothing.

How to quickly view your mobile number on iPhone

Recently I have changed my mobile number. I did not memorize it yet (learning to keep only indexes to information where it could be found - makes me forget numbers, names etc). So when you quickly try to view your number (for writing in form or giving to a friend) the easiest way is to 1) Go to home screen 2) Click on Phone 3) Navigate to Contacts search top area (taping on top bar) - and there you go

Quit MacOS Mail.app safely

It is very unlikely, but Mail.app that comes with MacOS is sometimes very buggy. Often it does not quit safely, and you have to kill it using Activity Monitor. It is especially annoying when it prevents computer from Shutdown. There is one trick, that at least for me - works every time. Before you quit the Mail.app - turn all accounts offline: Wait until all accounts move to offline mode (Flash sign at the end of account) and quit Mail.

Removing ".picasaoriginals" on uX system

Often I am facing one and the same issue - deleting backup folder of Picasa. There are usually lots of rotated images or movies. So usually this is the first place to search for free space. Here is one very short way to delete these subdirectories: cd ~/Pictures find . -iname '.picasaoriginals' -exec rm -rf '{}' \; This will remove all subdirectories from your “Pictures” folder that have name .

'Preview' crashes under Mac OSX Lion - FIX

It happened, that when I upgraded to Lion, for some reason Preview stopped working. This was new to me - usually I don’t expect such behavior under Mac OS. Seems that lots of people had this, especially the ones that have upgraded MBP with SDD and having HDD at the place of Optical Drive. In this case you make SymLinks in your home directory pointing to HHD for Downloads (for Photos, Music, Movies or anything that you can afford to play from slow media and takes more space, which is expensive on SSD).

RSA SecurID does not work on Mac OSX Lion - UPDATED 2

Today I have tried to connect to my company’s VPN. Few days ago I have already upgraded my Snow Leopard with Mac OSX Lion. When trying to start RSA SecurID to obtain my token, the application responded with: “Error loading the application. Contact your administrator.” When trying to search for solution, I found this post in Apple support forums: https://discussions.apple.com/message/15741858#15741858 There some guy from RSA says that they know about the issue and are working to fix it for next version, which will be available in September.

Finder consumes 100% CPU

Recently I have mentioned that my Mac is unusually busy, even when I am not compiling code, but just browsing of Internet or files. Running Activity Monitor - it was showing Finder on top, almost all the time consuming 100% of CPU. Event with 2 cores - Mac was struggling with some simple tasks. I thought at this moment - I cannot believe I will have the same stupid stuff like on Windows, when there is some missing Network Resources.

Running WebEx session under MacOS

If you are working for large international company, or just participate in projects that are executed by teams/people in different locations - it is likely that you have to work with WebEx. It runs quite soothly on Windows XP/Vista/7 under Firefox, Internet Explorer. But when you go to Mac - suddenly you stick with the message “One moment please” And this is the last and only thing that you see on you browser.

Black Leopard

This is post for Mac fans - everyone else should leave know. I used to love dark themes when working in Linux desktop. Even on Windows I used to set a dark theme, so that it doesn’t bother my eyes. Something that I love for Gnome and Kde desktops is customization - you can make your UI look the way you want, the way you like it. Most of the time, I used to set my Linux desktop to look like Mac :-P, but this is something else to be discussed.

Improving Home wireless experience

I used to have at home a network, based on Linksys WRT54G router - classical model, that served me already 2-3 years (I even don’t remember when I got it). It bothered me for a long time, that when trying to browse with iPad in one of the rooms - I used to loose network signal, or it was so fuzzy so that the pages did not load. At last I made a test and realized that the bottleneck in my network is the wireless rooter - it was even limiting my Internet speed in it’s best performance.
