Hello Video World

Here is a short video I created on my experiences in using the new features in youtube video editing.

Whats new in Youtube videos-

1) My account can now upload more than 15 minutes of video

2) I can edit the videos online without any software at http://www.youtube.com/editor

3) I can also create a video straight from the Web Cam at http://www.youtube.com/my_webcam and http://www.youtube.com/my_videos_edit

4) I thought but eventually decided not to use the Animation features (for free) at

http://goanimate.com/signup ( I can login using my Google Account !)

5) Since I hope to keep my videos seperate- I created a new video at the awesome new features in Blogspot at

http://videosforkush.blogspot.com/ (seperate blog post on that later) and then I just share my videos using the Share feature in Blogspot (big discovery- the Twitter button has been demoted from the share this by you-tube button hierarchy)

5.6) I can preview the features side by side as well

6) I still wish Youtube has some feature to help me capture the screen so I can make training videos at a faster rate so I no longer have to use Camtasia

Video killed the Radio Star- Yup

Heres the final video-

Juicy Data Visualizations

I was just checking out the stuff at http://analyticsvisualizations.appspot.com/juicekit/AnalyticsVisualization.html

Basically you login using your Google Analytics account (or actually uses the Google Analytics API) and bingo you can see the referral flow or tree for keywords to your website.

It is very  very cool stuff by http://www.juiceanalytics.com/

One particular dashboard I have been thinking of is- uses Google Analytics data to not only show trends in traffic but also forecast traffic for posts using certain keywords or categories (assuming simple time series + X forecasts)

!

Google APIs

You can go to https://code.google.com/apis/console/b/0/

 

Unlike Android and other free stuff these APIs are very promising for revenue generation as some of them are very unique to Google itself, and already some are being offered on a Pricing Tier. There are 18 APIs in total with 3 APIs having Pricing while the rest are in beta stages.

I am just listing down all the APIs in one place – Continue reading “Google APIs”

New Look Gmail


Now if only they could sell it better to counter MS exchange

What’s new in Gmail?

  • Preview Gmail's new look

    Preview Gmail’s new look

    Gmail is getting a cleaner, more modern look over the next few months. For a sneak peek at some of these changes, check out the “Preview” and “Preview (Dense)” themes on the Themes tab under Settings.

  • What’s been keeping us busy…

  • New languages for Gmail on iPhone and Android

    New languages for Gmail on iPhone and Android

    Now you can point your phone’s browser to gmail.com and get Gmail in 44 languages, complete with label support, an outbox for messages composed while offline, the ability to mute messages, and more. Watch the video or learn more.

  • Get through your email faster with Priority Inbox

    Get through your email faster with Priority Inbox

    Email is great, except when there’s too much of it. Priority Inbox automatically identifies your important messages and separates them out from everything else, so you can focus on what really matters. Learn more

  • Make phone calls from Gmail

    Call any phone in the US and Canada for free and at insanely low rates internationally — right from inside Gmail. Make sure you have the voice and video chat plugin, then click “Call phone” at the top of your chat roster. This feature is only available in the US at this time.

  • A new look for Gmail and updates to Contacts

    A new look for Gmail and updates to Contacts

    We’ve pruned our pixels and made it easier to get to Contacts and Tasks. Once in Contacts, you can now sort by last name and add custom labels for phone numbers and other fields — two top requested features. Learn more

  • Google Buzz in Gmail

    Google Buzz in Gmail

    Share updates, photos, videos and more right inside of Gmail. Start conversations about the things you find interesting. Learn more at buzz.google.com or in the Help Center.

  • Gmail now even more secure: HTTPS by default

    Gmail now even more secure: HTTPS by default

    HTTPS encryption keeps your mail secure as it travels between your web browser and Gmail servers, so someone sharing your favorite coffee shop’s public wifi can’t maliciously read it. Banks and credit card companies use this same protocol to keep your online accounts safe. To protect your Gmail account, we’ve turned on the option to “always use HTTPS” for everyone. This added layer of security can make Gmail slower, so if you don’t use unencrypted wireless connections, you can choose to disable this option in your account Settings. Even if you change this setting, Gmail will always encrypt the login page to protect your password. Learn more

  • More storage for less money

    More storage for less money

    If you need more space for your email and photos, you can now buy 20 gigabytes of storage for only $5 a year. Extra storage is shared between Gmail and Picasa Web Albums and acts as an overflow if you use up your free storage. Learn more

  • New features for Gmail on iPhone and Android

    New features for Gmail on iPhone and Android

    Point your phone’s browser to gmail.com and enjoy Gmail complete with full label support, an outbox for messages composed while offline, the ability to mute messages, and more. Learn more

  • New in Labs: Got the wrong Bob? and Don't forget Bob

    New in Labs: “Got the wrong Bob?” and “Don’t forget Bob”

    Ever included Bob (your boss) instead of Bob (your friend) on an email by accident? Oops! Turn on “Got the wrong Bob?” and Gmail will check if you meant to include Bob Smith rather than Bob Jones based on the groups of people you email most often.

    With “Don’t forget Bob,” you can start composing an email to a group of people, and Gmail will suggest other contacts you might want to include. Check out these experimental features and more on the Labs tab under Settings.

  • Four more themes

    Four more themes

    Make Gmail look like a calm patch of grass or an old school video game. Can’t decide? Choose “Random” and cycle through a different theme each day. Check out all available themes from the Themes tab under Settings.

  • New in Labs: Message translation

    New in Labs: Message translation

    Turn on “Message translation” from the Labs tab under Settings, and whenever you receive an email in a language other than your own, Gmail will automatically translate it into a language you can understand with just one click.

  • Tasks: the first graduate of Gmail Labs

    Tasks: the first graduate of Gmail Labs

    Available in Gmail, Google Calendar, iGoogle and on your mobile phone, Tasks is the simple to-do list that’s with you everywhere you go. Click “Tasks” above your chat list to get started (no need to turn it on from the Labs tab anymore). Learn more

  • Drag and drop labels

    Drag and drop labels

    You can now drag labels onto messages and messages into labels, just like folders. The labels you use most often are easier to access right above your chat list. The rest are hidden but still accessible under “more.” Customize which labels you see from the Labels tab under Settings. Learn more

  • New in Labs: YouTube, Picasa, Flickr, and Yelp previews

    New in Labs: YouTube, Picasa, Flickr, and Yelp previews

  • New in Labs: Undo send

    New in Labs: Undo send

    Oops, hit “Send” too soon? Give yourself a grace period of a few seconds to cancel sending, then edit your message before sending again. Turn it on from the Labs tab under Settings.

  • Tasks mobile

    Tasks mobile

    Take your to-do list everywhere you go. Just go to gmail.com/tasks from your mobile browser.

  • New in Labs: Offline

    New in Labs: Offline

    Make Gmail work even when you’re not connected to the internet. Turn on offline access from the Labs tab under Settings.

  • Labels: auto-complete and move to

    Labels: auto-complete and “move to”

    The buttons and menus at the top of your inbox look a bit different: there’s a new “Labels” button that makes labeling messages even easier. Turn on keyboard shortcuts and hit “L” to bring up your labels, and auto-complete will take it from there. Use the “Move to” button to label and archive in just one step — just like you would with a folder. Learn more

  • Gmail stickers

    Gmail stickers

    Gmail is usually all about speedy electronic communication, but for a limited time we went old school with snail mail. If you sent in a self-addressed stamped envelope, we’d send you some free Gmail stickers. Free stickers are no longer available, but you can see what they looked like on the Gmail blog.

  • Fast PDF previews

    Now you can preview PDFs right in your browser without waiting for them to download and open in another application. Just click the “View” link next to any .pdf attachments you receive.

  • New in Labs: Tasks

    Keep track of what you need to do with a lightweight task list right inside of Gmail. Just click and type to add new tasks, convert emails into tasks, and (most satisfyingly) check them off as you’re done. Once you turn on this Labs feature, look for the Tasks link to the left of your inbox under Contacts. Turn on tasks and more from the Labs tab under Settings. Learn more

  • New in Labs: Text Messaging in Chat

    New in Labs: Text Messaging in Chat

    Send SMS text messages right from Gmail. You chat from your comfy computer and reach your friends on the go; they get your messages as texts and can peck out replies on their little keyboards. Turn on SMS text messaging and more from the Labs tab under Settings. Learn more

Hackers for a better world

Well it is summer here in Delhi, India and hacking season has just begun.

Some noteable hacks that have already played-

1) The adventures of Sony Websites and bumbling administrators

http://www.computerworld.com/s/article/9217273/Sony_Pictures_falls_victim_to_major_data_breach?taxonomyId=142

2) The loose passwords of InfraGard as played by Lulz Security

http://www.computerworld.com/s/article/9217320/LulzSec_claims_it_hacked_FBI_linked_organization

3) PBS website hacked to revive Tupac is alive myths.

http://blogs.forbes.com/andygreenberg/2011/05/30/pbs-hacked-after-critical-wikileaks-show/

4) Iranian computers hacked

http://redtape.msnbc.msn.com/_news/2011/06/03/6781474-anonymous-says-it-hacked-iranian-government-email-server

5) Google hacked (not by China)

http://www.zdnet.com/blog/security/google-chrome-hacked-with-sophisticated-exploit/8626

6) Google hacked (again by China)

http://googleblog.blogspot.com/2011/06/ensuring-your-information-is-safe.html

7) US State Department hacked (by you know who)

http://wikileaks.ch/

8) Iranian nuclear reactors hacked (old news but we like this one)

http://www.bbc.co.uk/news/technology-12465688

9) Julian Assange hacked

http://www.guardian.co.uk/media/2011/feb/07/julian-assange-prosecutor

okay Julian got hacked by the oldest hack trap in the world but it is still pertinent.

So how the fuck do we control these evil hackers.

  1. Show them money
  2. Show them Jesus
  3. Throw them in Jail

The correct solution to bring talented members of the technical community back into the nice air contioned corporate tent of technology is to-

  1. Sponsor Hack My Website Contests- Winners have to share techniques
  2. Sponsor Hack this Search Engine Rank Contests- Winners have to share technique
  3. General Amnesty for people who have hacked before provided they share techniques and agree to join security teams.
  4. Sponsor hack this login id contests- Winners have to share techniques and work to develop fool proof system.

Unfortunately this will never happen. even the big grand Daddy , Google is willing to define hacking contests only in the narrow frame o technical hacks, rather than a system breach hack. Because system breach hacks generally happen at the people level.

Internal cover your assets mentality prevents technology and media employees from reaching out and helping create a secure online platform, thus harming shareholders.

Destruction testing (even in a controlled sandbox) of online systems would reveal the underbelly of corporate information technology.

I mean who wants to sponsor a hack contest that makes you look bad, when it is much more expensive to have a hacking attacks that decreases share price, but doesnot affect your salary.

We have gone in for crowd sourced coding.

How about incentivizing crowd sourced systems design for secure and free internet.

http://rewiredstate.org/ does it.

Apparently UK is more open for hackers than the US.

Data Mining to change the world of health care

 

http://www.heritagehealthprize.com/c/hhp
Heritage Health Prize, a $3 million competition to predict who will go to hospital and for how long.
So as not to overwhelm anyone, we will be releasing the data in three waves. Today’s launch allows people to register and download the first instalment, which includes enough data for people to start trying out models. It includes claims data from Y1, information on members and the details of hospitalizations recorded in Y2.
The next instalment will be released on May 4 and will involve the release a more comprehensive dataset, including claims for later years as well as the test dataset against which entries will be judged. It is at this point that we will open up the competition to entries, reveal the performance threshold and begin posting the leaderboard.
Finally, the last release happens on June 4 and will include some ancillary data of prescriptions and lab tests.
Kaggle members don’t sign up again. To register, simply login and accept the rules before downloading the data.
Finally the Twitter hashtag for the competition is #drflix. Help spread the word.
