Can't exit Toddler Lock on Android phone

Toddler Lock will lock your Android phone completely so you can give it to a baby or toddler to play with. The only danger from the kid is that it may throw your phone and break it. But other than that, the kid will not be able to damage the phone by unlocking it and messing with what's inside.

Here's the problem. The security of Toddler Lock is so tight that it would seem the only way to exit out of the app is to tap four corners of screen in a clockwise direction. (Note that you have to tap the four corners one after the other. Tap any corner, remove your finger, tag next corner in CW direction, remove your finger, and so on. Some people seem to think you need to hold all corners simultaneously which is wrong.) You may think a restart may also unlock it but even pulling out the battery for minutes (or perhaps hours) will not help. You will be stuck in Toddler Lock no matter what.

This is fine until my screen started having problems. Two of the four corners I had to touch to exit Toddler Lock did not register touches anymore. This is fine for my normal usage as Android is quite versatile enough to be usable even if small parts of the screen do not register touches anymore. But I forgot this and launched Toddler Lock. This is where I got stuck in a seemingly infinite blackhole of being stuck on Toddler Lock. I even sent an angry email to the developer in ALL CAPS!

I tried the following (none helped):
  • Power down the phone.
  • Restart the phone.
  • Pull out the battery and put it back in.
  • Pull out the battery, leave it out for five minutes, put it back in.
  • Try to use "adb" tool in Android SDK (unfortunately my USB Debugging option was off)
  • Try to remote uninstall Toddler Lock via Google Play website but I think my device is too old for that. (THIS is what you should do if you have a newer device.)
If nothing of the above helped you, here's what you can try. These are not step-by-step instructions, but more like "mess with it until it works" instructions so just keep trying different approaches. I was just trying various things in panic mode to get my phone unlocked, so I'm just gonna write most of what's below in first person describing what I did. You may not have to do everything.

TIP: The developer has replied with a (perhaps) easier method of rescuing the phone. Of course this is model-dependent but still worth a try: "To exit Toddler Lock, you can try starting the phone in "safe mode", which will prevent Toddler Lock from starting. On most phones, you enter safe mode by restarting the phone while holding down the "menu" button, and continuing to hold it down until the home screen appears." Safe mode for certain devices: HTC/Nexus1/Droid, HTC Desire HD. Getting out of safe mode: link.

NOTE: If you had enabled Airplane Mode (flight mode) in Toddler Lock settings, you can attempt to disable it via the power menu. Hold the power button down and in the menu you get, if you find an "Airplane mode" option or similar, tap it. If you don't have that option, or it's not helping, you can still try some of the steps below, but you may most likely end up having to replace your digitizer (bring the phone to any mobile phone repair shop tell them to change the digitizer - NOT the display itself! - to a new or working one).
  • Get another phone and make a call to the phone stuck on Toddler Lock.
  • When the phone rings (press any volume button once to mute the ring then), try pressing home button, power button etc. to somehow get to the lock screen or the screen to answer call.
  • My phone had a normal security pattern so this kinda helped. I got to the security screen and entered wrong code 5 times so that I can tap on the Forgot Pattern? button.
  • Somehow I ended up on the lock screen (swipe to unlock, pull ring to unlock, etc) as I kept messing with the phone trying to answer the call. I made a second call again. The lock screen gave me options to answer or reject the call. I answered it and left the call ongoing.
  • On the call screen, I pressed Menu > People to get to the contact list. Now I had to unlock the screen, which I did. The People app crashed, so I did Menu > People again. I could now see the contact list (You may not need to do this)
  • I pulled down the notifications drawer (you can't do this when the phone is locked even in a call), then tapped the Quick Settings tab, selected All Settings.
  • I went into Applications > Manage Applications > Toddler Lock > Force Stop > Clear data > Clear cache (was disabled) > Clear defaults > Uninstall > OK.
  • Before the above, I had also launched my TaskPanel task manager app and force-quit the Toddler Lock entry there, but this may not be necessary.
  • If you cannot get into Settings you may have to wait till you have notifications about app updates, then tap on that to get to the Market (Play Store) app, and uninstall Toddler Lock from there. You could try pressing Home to see if you can get to your actual home screen, but I suspect it will throw you back into Toddler Lock again.
Hope this helps anyone who is stuck on Toddler Lock! It's damn ridiculous that even pulling out battery for 5 minutes isn't going to reset Toddler Lock... which toddler on earth is gonna try that in its attempt to unlock the phone from child lock?

Disable auto save in JetBrains IDE software (IntelliJ IDEA, PyCharm, PhpStorm)

JetBrains provides the following IDE software:
IntelliJ IDEAPhpStormPyCharmRubyMineWebStormAppCodeCLion Google also provides Android Studio which is powered by the IntelliJ platform.

If you come from a different IDE such as Eclipse, you will be unpleasantly surprised to find that JetBrains-branded IDEs automatically save everything the moment you look away. The proponents argue that as you work on your project, you should not have to worry about saving files. But to others, this auto-save behavior which is enabled by default is a curse that catches them by surprise, and a shocking departure from the workflow they are very much used to.

You can change the behavior by altering some settings.

Stop having to click Unblock on every downloaded file

CAUTION: The blocking of downloaded files in Windows is a security and safety feature to help prevent your computer from being infected by viruses and other malware. Only disable this feature if you know what you're doing.

I had been plagued by this annoyance since the days of Windows Vista. Any downloaded file, no matter what browser I use, gets tagged as "blocked" by Windows. You can open downloaded documents even though they are blocked, but when you run a downloaded application (such as a setup file) you're presented with a "Security Warning" before you're allowed to run it. It's worse if you extract a downloaded ZIP file with the Windows' built-in ZIP management. Every extracted file is blocked by default.

Being a geek who finds unnecessary "security" prompts annoying, the first thing I do in Windows is to disable the User Account Control (UAC). But I couldn't quite figure out how to disable blocking of downloaded files until …

Setting up a local Oracle XE database and importing DMP file

The experience of setting up a local Oracle Express Edition database is not a straight-forward as it should be. The following is supposed to outline what could go wrong and how to go about it the right way. It also includes importing a DMP file (a dump) from another system.
First of all, download the installer from Oracle website. You will need to sign-in to download - the account creation is free. Be sure to choose the correct bit as per your computer (x64 or x86).Extract the download and install XE by running DISK1\setup.exe (and feel nostalgic of the floppy disk era). During installation, you will need to choose a new password. There will also be some details displayed after you enter the new password, such as folders and ports.Be sure to save both password and details in a text file for future reference.I saved it as C:\oraclexe\details.txt.Save password only if it's generic and you are likely to forget. The installation will take a while, but usually, no restart is necessary.O…
