Fool’s Day Parade in New York

April 1, 2009 10:51 am

The New York April Fools’ Day Parade was created in 1986 to remedy a glaring omission in the long list of New York’s annual ethnic and holiday parades. These events fail to recognize the importance of April 1st, the day designated to commemorate the perennial folly of mankind. In an attempt to bridge this gap and bring people back in touch with their inherent foolishness, the parade annually crowns a King of Fools from parading look-alikes.

The public is encouraged to participate, in or out of costume, with or without floats, and may join the procession at any point along the parade route. Floats can be no wider than 10 feet and no longer than 25 feet. They can be self-propelled, towed, pushed or pulled. Customized bicycles, tricycles, baby carriages and aerial balloons are welcome. All participants are costumed look-alikes, and the Parade Committee assumes no liability for damages caused by satire. Parade floats and marchers must be at 59th Street and Fifth Avenue no later than 11:30 a.m.

Girls in Tech (re)Launch Party

March 22, 2009 2:42 pm

On Tuesday, March 31st the Girls in Tech tribe is hosting its (re)launch party. Back in September 2008 I attended the first Girls in Tech party that occured as part of Web 2.0 Expo here in NYC. Zahra made fast friends with the crew, and I enjoyed my relatively priviledged status as one of the three or four male supporters in the room.

The 2009 launch party (which is open to men as well as women, by the way) features Juliette Powell, a media entrepreneur, a community catalyst and author — as guest speaker. She will also be signing copies of her latest book. The event will also feature swag bags, raffle prizes (the girls are raffling a KaraB laptop bag and a $100 driving credit from Mint), drink specials, and complementary hors d’oeuvres.

The relaunched New York chapter’s program of events will focus on network mixers, weekend workshops; a summer dinner cruise; a money-smarts seminar for freelancers and small business owners; and participation in Girls in Tech University.

Authenticate your own SSL certificates with a rogue Certificate Authority

January 12, 2009 12:15 am

On December 30, 2008, at the 25th Annual Chaos Communication Congress in Berlin, a security team called MD5 Collision, Inc. presented a paper that declared the Certificate Authority system protecting commerce on the Internet to be entirely compromised.

We have identified a vulnerability in the Internet Public Key Infrastructure (PKI) used to issue digital certificates for secure websites. As a proof of concept we executed a practical attack scenario and successfully created a rogue Certification Authority (CA) certificate trusted by all common web browsers. This certificate allows us to impersonate any website on the Internet, including banking and e-commerce sites secured using the HTTPS protocol.

Our attack takes advantage of a weakness in the MD5 cryptographic hash function that allows the construction of different messages with the same MD5 hash. This is known as an MD5 “collision”. Previous work on MD5 collisions between 2004 and 2007 showed that the use of this hash function in digital signatures can lead to theoretical attack scenarios. Our current work proves that a least one attack scenario can be exploited in practice, thus exposing the security infrastructure of the web to realistic threats.

As a result of this successfull attack, we are currently in possession of a rogue Certification Authority certificate. This certificate will be accepted as valid and trusted by all common browsers, because it appears to be signed by one of the root CAs that browsers trust by default. In turn, any website certificate signed by our rogue CA will be trusted as well. If an unsuspecting user is a victim of a man-in-the-middle attack using such a certificate,  they will be assured that the connection is secure through all common security indicators:  a “https://” url in the address bar, a closed padlock and messages such as “This certificate is OK” if they chose to inspect the certificate.

This successful proof of concept shows that the certificate validation performed by browsers can be subverted and malicious attackers might be able to monitor or tamper with data sent to secure websites. Banking and e-commerce sites are particularly at risk because of the high value of the information secured with HTTPS on those sites. With a rogue CA certificate, attackers would be able to execute practically undetectable phishing attacks against such sites.

Free 25gb Net Drive On Your Desktop

December 18, 2008 3:54 pm

Windows Live SkyDrive is a free service from Microsoft that gives you an impressive 25 gigabytes of cloud storage space on their servers. Folders and files can be private, shared with a group, or completely public.

The space alone makes this worth the sign-up. This service becomes truly Elite when you mount it on your PC as a virtual hard drive.

The Gladinet client allows you to mount cloud storage from SkyDrive (as well as from Amazon S3 and Google) as a virtual folder from within Windows Vista and XP.

The process is so simple that it doesn’t even require instructions. Just download & install it, enter your credentials, and then add your files.

Howto create & seed your own torrent

December 5, 2008 4:56 pm

Downloading a torrent is easy, but the process for creating and sharing one of your own is a little more challenging. The following is a quick overview of the process.

Using uTorrent

  1. First open uTorrent and select File >> Create New Torrent.1
  2. The Create New Torrent window will appear.  Browse to the location of the torrent directory.3
  3. Locate the the file or folder you want to create a torrent from, select it, and click OK.2
  4. Next, enter the trackers where you want the torrent to be found by others. You can use one or more trackers, but in general one is enough. Here are some good trackers you can use:

    http://open.tracker.thepiratebay.org/announce
    http://www.sumotracker.com/announce http://inferno.demonoid.com:3391/announce

  5. In the comment box add any information relevant to the torrent.  Also check the Start Seeding box so the torrent begins uploading after it is created.  Finally, click on Create and Save as.3
  6. Windows Explorer will once again open so you can create a name for the torrent and choose where to save the new torrent file. I suggest creating a “Torrents” folder in your My Documents and putting them there.
  7. The new torrent should appear in uTorrent and begin seeding across the Internet. If you see a red arrow next to the torrent, that means it hasn’t been added to the tracker(s) you selected yet. Many trackers delay new seeds for processing, virus-checking, and the like. You can right-click on the new torrent and select Update Tracker to speed up the process. Continue clicking it until the red arrow turns green.8

Other Torrent Options

If you simply wish to create a new torrent without seeding it, use MakeTorrent instead. Its a small application for Windows and Linux that creates the torrent file and nothing else.

Elite iPod Organizer

Access Your iPod Without Using iTunessharepod

I found two free and efficient replacements for the 800lb gorilla of music programs called iTunes.

When I’m in rush the last thing I want to do is spend 10 minutes loading music onto my iPod. Opening iTunes takes forever, its a huge program. Then it doesn’t already contain the new music I want to put on my iPod, so I must hunt around and load it. Then it searches for album art…

It is a choice between YamiPod and SharePod, both free, tiny, and easy to use. Both applications offer the integration of an iPod without the restrictions of the iTunes environment.

Both programs can be loaded onto your iPod and executed without copying it back onto a PC. This is perfect for corporate workers who do not have administrative access to their desktop. This is also good news for support technicians who can now refuse to install iTunes with a clean conscience!

    YamiPod features:
  • stand alone program, no installation required
  • mp3 and AAC files can be copied to/from iPod
  • read/write access to mp3 id3 and AAC infos
  • playlist support (On-The-Go included)
  • auto-download new versions
  • advanced song import/export settings
  • 2 restore features
  • built in music player
  • iPod information
  • 2 search features
  • remove duplicated tracks
  • find lost music files
  • easy ratings edit
  • PC to iPod synchronization
  • create and edit notes
  • automatically update song playcounts
  • News RSS and podcasts to iPod upload
  • export song lists to HTML or plain text files
  • multiple iPods support
  • Last.fm support

    SharePod features:
  • Add & remove music and videos from your iPod
  • Add, remove and edit playlists
  • Add & remove album art
  • Copy music, videos and playlists from your iPod to PC
  • Import music/videos into your iTunes library, including playlists and ratings
  • Built-in music player
  • Tag editing
  • Drag n’ drop to and from Explorer
  • Backup and restore music library
  • Simple, clean interface

Between the two, SharePod is the Elite choice despite its smaller feature set. In this case simple is better.
