Root Telus Rogers Koodo LG G4 H812 by downgrading from Marshmallow to LollyPop

There is  no root available for LG G4 H812 Marshmallow (MM) devices now, but root is available for LollyPop (LP). The strategy here is to downgrade to LP from MM and root the device. You need to disable the OTA updates, since the root will be lost if you upgrade.

1. Download stock KDZ from https://forum.xda-developers.com/g4/general/canadian-guide-complete-source-lg-g4-t3212449
   1. I downloaded "H81210n_00_1204STOCKkdz". All carriers are cross compatible (Bell, Rogers, Telus, Wind)
   2. If you have downloaded 10n kdz, you should download 10n rooted image. I downloaded "H81210nROOTEDrogers.rar"
2. Downgrade from Marshmallow to LP https://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803
   1. TO GO BACK TO LP FROM MM - Open LGUP on your computer, select "Upgrade", click on FILE PATH and point it towards your LP KDZ. Close LGUP and re-open LGUP. Make sure you select REFURBISH this will do a full wipe, tick BIN file. Press Start. Make cup of tea and be patient 
      
      If you are worried about losing your data after a full wipe, why not use the LG Bridge software to backup and restore.... it works fine!
      YOU WILL LOSE ROOT!
      There is no need to enter download mode! LGUP will do it for you.
3. Install ROOT https://www.reddit.com/r/lgg4/comments/3ir4zn/guide_how_to_root_all_versions/

4. Install Xposed using https://forum.xda-developers.com/g4/themes-apps/guide-installing-xposed-locked-t3181593
1. Follow instructions below worked for me
2. Download FlashFire version 0.24, and xposed-v87-sdk22-arm64.zip
3. Set your date of phone back to June 2015 .
4. v0.24 has only one option (Auto-mount), which I left unchecked.
5. 20 minutes of blank screen, then some flashfire text and a reboot, it optimized apps, and then finished normally.
6. Install the xposed installer apk (XposedInstaller_3.0_alpha4.apk) and it reports v87 is active

Lenovo Thinkpad T410 audio through displayport

Getting audio to pass through to TV when using displayport to HDMI cable

DisplayPort is actually capable of tranmitting audio and video. However some manufacturers or OEMs do not implement the audio pass through, luckily Lenovo has implemented this correctly in their Thinkpad T410.

Follow the step to get your laptop audio to TV.

1. Start playing the video.
2. When video is playing, go to Control Panel -->Sounds-->Playback tab
3. You'll see a list of audio playback devices and TV (or amplifier if you are using one) should be one of the options. 
4. Just choose TV and set it as the default audio device 
5. The audio will be passed automatically to the TV from now on.

How to get rid of the Evernote "Synchronization complete" notifications?

Tools -> Options -> Sync -> Uncheck "Enable sync notifications"

Solution - LG G2 stuck in TWRP recovery and does not boot to Android

If you get stuck in TWRP with no hope of booting to OS, here is the solution. Usually in these cases, any hardware button combinations will take take you to TWRP (and not to bootloader etc.)

This normally happens when you are trying to install an OS update from LG and your phone has custom recovery like TWRP installed.

Looks like you need to rebuild the boot system.

At TWRP recovery, go to advanced, select TWRP terminal command and press select (you do not have to select any file)

Type

dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota

(Remember - no space between sdcc.  and 1) hit Enter and wait for the command to execute

type

dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc

then hit enter and wait for the command to execute.

Reboot. Hope fully your phone will boot to Android OS. If not go ahead and install your favorite ROM. My favorite is CloudyG2.

This has worked for LG G2 D803 version and hopefully will work on other versions.

Flash tomato on Asus router RT-N10P

These steps are adapted from http://tech.surveypoint.com/posts/tomato-firmware-install-on-asus-rt-n10p-router/. I had simplified the procedure for you here.

• Download the appropriate tomato firmwire. I used tomato-K26-1.28.RT-N5x-MIPSR2-121-Max.trx. You can download it from http://tomato.groov.pl/download/K26RT-N/build5x-121-EN/. Newer version (latest is v124) are available in http://tomato.groov.pl/download/K26RT-N/ .
• Download and install asus firmware recovery program from http://support.asus.com/download.aspx?SLanguage=en&p=11&m=RT-N10P&hashedid=wU7ZgKmZf29DK6D0
• Start the firmware recovery program.
• Select the firmware (do not press upload yet)
• Unplug the power from the router (no need to use static IP in your computer).
• Holding down on the reset button, plug in the power to the router.
• holding the reset button till the power light blink slowly,
• Press the upload button in the recovery program. 100% upload will be completed in a minute.
• Wait for 30 minutes more without disturbing the router. You'll probably see the errors in the firmware restore window. Do not worry about that as long as wait for 30 min.

• Connect to 192.168.1.1 in your web browser.
• Switch off the router, press wps button and turn on the router --> to reset the nvram.
• Configure the router and have fun.

Extend the whatsapp subscription by one year using a landline number

If you do not want to pay for whatsapp subscription, you can extend the license for one year with this small workaround. You need to have a landline number for this to work.

1. Delete the expired account. This option is available in settings>Account. You need to type your number before you can delete the account.
2. Press change number available in settings>Account. 
3. Type in the landline number. Whatsapp will attempt to verify this number by sending SMS. Since this number is landline, there will not be any SMS received.
4. Whatsapp will wait for 5 min. After 5 min is expired, whatsapp will give you an option to call you at the landline number with the confirmation number.
5. Confirm to call the landline number and input the confirmation received on landline number.
6. You got one year free subscription to whatsapp.

Map Box.net drive in computer using WebDAV

We can create a local box.net virtual drive in computer using WebDAV. We will be able to do most of the file operations (copy/paste/rename) from local computer. Note that the local drive will be only a link to your box.net folder and contents, which means the actual folders and files will not be downloaded to local computer (like Dropbox).

In Windows 7,

1. Go to (My) computer.
2. Click Map network drive
3. In the folder field, write  https://www.box.net/dav
4. After few seconds, there will be prompt for user name and password. Provide your box.net user name and password.
5. Windows will create a local drive pointing to your box.net folders.

How to Convert Magnet links into Torrent Files for Dropbox

Some of the torrent sites like Piratebay are now offering only magnet links. If you would like to start downloading remotely using dropbox, the magnet links won't work. To remote start downloading, you need the actual .torrent file.


Steps to follow:

1. Click the magnet link. Your default torrent client (for example utorrent) will start. Press OK.
2. After the download has started, go to %appdata%\uTorrent\ using Windows Run command (for other clients look for appropriate folder in  %appdata%.)
3. You will see the .torrent file there (if the .torrent file is not there, it means the torrent downloading has not yet started - wait for couple of minutes. Once the download is started, the .torrent file will show up).

Now you have the .torrent file to email or copy to Dropbox.


Option 2: You can try to use http://magnet2torrent.me. However, it may not work all the time. It may work, if your torrent is a popular one.

Calculation of Vapor Pressure using HYSYS.

1. Create the stream with required composition.

2. Enter the desired temperature in the stream properties.

3. Set the vapor fraction to 0.

Pressure calculated by HYSYS will be the vapor pressure of that stream. Note that HYSYS is actually calculating the bubble pressure when vapor fr is set to 0. But bubble pressure is the vapor pressure at the specified temperature (good for any temperatures below critical temperature).

Note that vapour pressure greater than operating pressure (for a multicomponent mixtures) just means that the liquid is flashing (Vapor-liquid mixture).


To keep a liquid phase the operating pressure of a two phase stream is usually greater than the liquid vapour pressure. Otherwise the liquid would flash so that the vapour pressure of the new liquid is below the operating pressure. This means for a two phase multicomponent mixture flow, the vapour pressure of liquid at operating temperature (not entire mixture) is equal to the operating pressure.

DD-WRT Client bridge on Linksys E3000.

These steps are adapted from http://www.dd-wrt.com/wiki/index.php/Client_Bridged. However following those steps exactly did not work for me. So I modified the steps.

My Access point router IP address was 192.168.1.254 (not a DD-WRT router) and E3000 router IP address was 192.168.1.1.

1. Download and install a recommended build for your router. DO NOT USE SP1. I used Kong build 19200M (SP2 build).
2. Do a HARD reset on your router (press the reset buttom on the back of E3000 router for at least 15 seconds).
3. Connect a cable from your computer to the LAN port on your router.
4. Set your computer to a static IP address of 192.168.1.9
5. Set your browser to 192.168.1.1 and open the dd-wrt webgui.
6. You should be asked to change your password and username. Carefully type these in. (If you aren't asked for a password and username, do a hard reset, this time doing it properly!) Hit change password.
7. Go FIRST to wireless, wireless security and enter the security type and key that matches your primary router.
8. Hit SAVE, (NOT APPLY)
9. Go to the wireless, basic settings page and change the wireless mode to Client Bridge.
10. Your wireless network mode, channel and encryption should be set to the same as the primary router.
11. Set the wireless network name to exactly the same as your primary router. Make sure spelling and capitalization match.
12. Hit SAVE, (NOT APPLY)
13. Goto Setup, basic setup and enter a router Local IP address of 192.168.1.1. (it will be already that IP address). Leave subnet mask at 255.255.255.0.
14. Set the Gateway IP to the IP of your primary router. (192.168.1.254 in my case)
15. Leave Local DNS blank
16. Change your timezone and DST to match where you are.
17. Hit SAVE, (NOT APPLY)
18. Goto Security, Firewall. 
19. Disable SPI Firewall
20. Hit Save and then Apply.
21. You are done. Wait for at least 5 minutes for the router to apply the configuration and get the internet connection from primary router. 

Full Vacuum Vs Half Vacuum (FV Vs HV)

Full Vacuum

FV - for vessels having steam as a signifacant component during normal operation (e.g. amine regenerators)
- for vessels operating under full or partial vacuum during normal operation
- for vessels that require steamout as part of routine operation

Half Vacuum
HV - for vessels that require steamout during maintenance only and does not have steam during normal operation

Interconnection tag number is P&ID.

Interconnection tag number is P&ID is called OPC.

"Interconnections (OPC) – are shown between lines (piping OPC) and instrument signals (Instrument OPC) present on two different P&ID sheets. Sometime these interconnectors are also assigned with a unique tag number. For easy identification of the connections between two P&IDs. A connector present on two different drawing connection a line or a signal carries the same tag number."
