YouTube Tips and Tricks

Awesome Progress Bar

Select the video and click type out "awesome" without quotes. The progress bar blinks vibgyor.

Play in HTML Format

Add /html5 at the end of any YouTube video URL to make it load as HTML5 which is fast and effective as compared to Flash

Add /html5 to video URL to play as HTML5 video

You can also navigate to to select it as the default.

Watch in Window Mode

If you replace watch?v= in the URL with v/, you can watch the video in windowed mode and skip having to sign in.

Keyboard Shortcuts

Don't use the Space Bar to pause a YouTube video. Hit "K" instead to instantly pause it! Similarly use "J" and "L" to jump back and forth by 10 sec respectively in the video. There are the mid-right keys on the keyboard. J-K-L are the standard keys in a video editor software.


L will also skip the ads.

If your YouTube video take a long time to load, press the down arrow to turn the loading symbol into a game of Tetris.

C toggles the caption.

Meanwhile M mutes the audio and F makes the video go full screen.

Watching Videos Like a Pro

Set your YouTube bookmark to . That way you will see the latest videos from the channels you subscribe to and not a bunch of useless recommendations

Every YT channel has a hidden RSS feed, so I used them to make Feedly my Subscription Box. It's a time consuming process but it's well worth the benefits:
  • Videos will ALWAYS show up, unlike in the ever-broken Sub Box.
  • Watched videos will disappear making way for the unwatched
  • Bookmark, "keep unread" or hide videos with one click.
  • Organize your feed into folders (similar to YT's Collections feature, but less convoluted)
  • Know exactly how many unwatched vids you have. Overall and in each folder.
  • Everything loads on one page

YouTube subscriptions on Feedly

If you want to give it a try, all you need is this:
Replace "username" with the name of the channel you want to subscribe to and paste the string into Feedly's search bar.

1080p on Firefox

HTML5 player may limit the videos to 720p. Try the following setting on Firefox:

  1. Load about:config in the browser's address bar and hit enter.
  2. Confirm that you are careful when the prompt is displayed.
  3. Search for media.mediasource.enabled. If the preference is set to false, you will have to change it to true.
  4. Double-click the preference name to set it to true and enable it.

Remove Distractions, use Feather

Remove all of the distractions from Youtube without a plugin by using It will basically change Youtube to what it was a few years ago, except there are no comments and it will load way faster.

Plugins allow more control. YouTube Options (Chrome) and YouTube Center (FireFox) work well,

Latch to Faster CDNs

Enter the following command into Windows cmd prompt (start->run->"cmd"):
netsh advfirewall firewall add rule name="FASTYOUTUBE" dir=in action=block remoteip=, enable=yes
This adds a firewall rule to reject certain CDN IP addresses, which in turn gets you a very blazing fast streaming.
To remove the firewall rule use the following command:
netsh advfirewall firewall delete rule name="FASTYOUTUBE"

Change your Skype settings and avoid DDoS attacks

If you know someone's Skype username, you can get their IP address.

The person can enable some options that stop non-contacts from getting their IP address with just their Skype username, but most people don't know how to do that.
It also isn't foolproof. You can be invited to a conversation by someone else, then everyone in there can get your IP address. Your IP address is then used to DDOS you.

DDOS stands for Distributed Denial of Service. You get so much data sent to your IP that it makes your internet connection largely unusable. Thus you lag a lot or disconnect from the game you're playing, which sucks if you're in the middle of a competitive match.

You can protect yourself better by using something other than Skype, or by buying a proxy and setting up Skype to use said proxy.

Proxy aside, here are some some Skype settings you can set to better protect yourself: Options -> Advanced -> Connection -> Uncheck "Use port 80 and 443 for additional incoming connections"
Options -> Advanced -> Connection -> Check "Allow direct connections to your contacts only."

Connection Settings

Options -> IM & SMS -> IM settings -> Select "Only allow people in my Contact list to send me messages"
Options -> Calls -> Call settings -> Select "Only allow people in my Contact list to call me"

Call Settings

Options -> Privacy -> Privacy settings -> Select "people in my Contact list only" for all three (and uncheck the two advertisement-friendly settings at the bottom)

How to check the processes and services run by svchost.exe

On Windows, applications are built as exe files and code libraries are built as dll (dynamic-link library) files. The dll files contain reusable programs such as database engines, 3D renders, graphing capabilities etc.

The application developers need not bother about writing these libraries all over again and can use these libraries by referencing the dll files in the application program.

Exe files can run as a process, but that is not possible for dll files. Windows needs an exe process to load the dll file(s) and then let other processes call a function in the dll code. One more reason for hosting dlls separately is that some of the code has to run as a super user and running that code from the application as a constrained user is not possible.

svchost.exe does the job of loading the dll files in a process with SYSTEM user.

One or more dll files are grouped by their functions and are loaded into the svchost.exe process. So based on the number of groups these dll files can form, several svchost.exe processes run on your computer.

Task Manager does not show what dll files are being loaded by each svchost.exe. You can run tasklist /svc /fi "imagename eq svchost.exe" from command line or Process Explorer.

How to check the processes and services run by svchost.exe

tasklist gives you an idea, but it is not super helpful. Let's look as Process Explorer (it is a free standalone program from MS)

When you hover above svchost.exe, it shows information similar to what tasklist /SVC does, plus the name of the service. If you right-click on the svchost.exe process and check the Services tab, you will see the path to the dll file(s) hosted by the process.

How to check the processes and services run by svchost.exe

If you find svchost.exe using a lot of CPU/RAM, you may have to drill down which service is causing the issue. If you are not able to locate proper information on the dll, it is likely a virus.

Get rid of animations and focus on task at hand

When you are closing, opening or minimizing windows, animation effects are rendered (I guess to make it look more dramatic). I can live without those animation effects, and if you are like me, you can turn off unnecessary animations by following these steps:

Get rid of animations and focus on task at hand
  1. Open the Control Panel and click on Ease of Access Center.
  2. Scroll down and click on Make it easier to focus on tasks.
  3. Scroll down again and check the option Turn off all unnecessary animations

  4. Apply the changes

SAP Process Integration Starter Guide for Basis Administrators

This is a starter guide for Basis Administrators to understand the architecture and various nuances of SAP PI Administration. This guide will be updated time to time, so I recommend you to bookmark and keep revisiting this page as you see fit.

SAP Process Integration Starter Guide for Basis Administrators

Enterprises run different software solutions to support their business processes. Not all of them are built and supported by SAP. These solutions are integrated one-to-one using various middleware solutions or customized programs or scripts.

When there is a change in one system or business process, multiple point-to-point interfaces are affected and are often expensive to change.

Although these point-to-point interfaces are using different technologies, there are recurring themes. Although there are recurring themes, code is not reusable because they were implemented using different technologies.

In 2003, SAP introduced NetWeaver, which helped them focus on providing a platform for integrating various aspects of business, including business processes (by using Exchange Infrastructure or XI). Later in 2005, XI was renamed to Process Integration (SAP PI).
