Benjamin Bratton: New perspectives: What's Wrong with TED Talks? at TEDxSanDiego 2013 - Re:Think by TEDxTalks

Benjamin Bratton, Associate Professor of Visual Arts at UCSD and Director of The Center for Design and Geopoltics at CALIT2, asks: Why don't the bright futures promised in TED talks come true? Professor Bratton attacks the intellectual viability of TED, calling it placebo politics, middlebrow megachurch infotainment, and the equivalent of right-wing media channels. Does TED falsely present problems as simply puzzles to be solved by rearranging the pieces? In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)

How to Find and Delete CPU Hoggers

How to use Windows Task Manager Effectively  
I installed a volunteer program that actually uses my bandwidth whenever my PC is idle. After some months and being informed my small netbook bandwidth wasn't helping, I decided to uninstall it. But whenever I run my defragmenter, the program's name was still flashing and for some reason, I found it hard to locate the program file to delete it. But thanks to the problem I finally learned how to use Task Manager to the full.
Here is how to find and delete stubborn CPU hoggers:  

1. Open Task Manager: ctrl+shift+esc
2. Click on 'Processes'
3. If you don't find the file you need, click 'Show processes from all users'
4. When your target file name appears, right-click on it then click 'Open file location'
5. When your file appears, you can delete it by clicking on 'Organize' (top left corner) then choosing delete. Or you can use your deleting or uninstalling app too.

Finally, my CPU isn't running 100% all the time! I have no idea how my netbook withstood that.

Overwrite your Deleted Data for Safety

Did you know that all your deleted files could still be hacked unless you overwrite them?
This tutorial will show you how to securely wipe or overwrite free disk space on any partition or disk using the inbuilt cipher command in Windows


1. Open (an elevated) command prompt or press Windows icon + R

2. Type the command below, and press Enter

The syntax required is: Code:

cipher /w:[drive]:\[folder]

where [drive] = drive letter, [folder] = folder name

If you want to wipe ALL free disk space on a particular drive, use this simpler syntax:


cipher /w:F:\

Another Adventure in False Positive

I think this PC problem was solved with a prayer. Read first before you say 'corny'.
I was normally surfing online when I noticed my battery monitor -- I was running on it, not with electric power. I tried to fix that then my PC suddenly shut down. When I tried turning it on, it would shut down again at Windows load. This happened about 10 times before Windows gave me the option of checking Startup. I allowed that and after the check, Windows said my 'registry is corrupt'. I thought how could that be when I stopped tweaking my registry a long time ago knowing it's a no-no. Windows allowed me to restart, did that, and the PC shut down again.

I tried turning it on again and again but it was no use. I gave up and assumed that my registry is indeed corrupted. I rested then tried blowing dust inside the PC away to make sure overheating is not the cause. I was taking a bath when it occurred to me that since the problem started with power malfunction, maybe the problem is my outlet socket.

My power adapter is connected to an octopus outlet. I took away the multiple outlet and inserted my adapter directly. My Pc turned on and worked again. That simple. It was just another 'false positive' from Windows -- again.   

My analysis: either my socket malfunctioned or a hacker used the socket. Hackers could do that -- especially when you’re on power smartmeter.     

The Importance of Dusting Inside of PC
You're working on an important manuscript you haven't saved. Then suddenly your computer screen blanks out. There is no possibility of recovering any file you haven't saved when that happens.  

I was lucky when it happened to me. I just tried to restart five times then my netbook went normal again. I researched how and why it occurred and the answer I found was so simple it surprised me: Dust stopped the fan inside netbook and overheating crashed or blanked it out.

So if ever this happens to you, don't panic and call your techie at once. Try first the tutorial below which is the most probable answer.

Additional tips:
You can use the SpeedFan app which monitors voltages, fan speeds, and temperatures in computers
Put dust-trapping cloth mats around your computer
