Guy Kawasaki’s Social Media Secret

05 Mar

Guy Kawasaki wears many hats.  He‘s the founder of Alltop.com, a bestselling author on social media and marketing, and still somehow manages to fit in about 75 speaking engagements each year. Here, Inc.com reporter Eric Markowitz chatted with Kawasaki to get his thoughts on how entrepreneurs treat social media—and how they’re doing it all wrong.

First, to what extent has social media changed the way companies and entrepreneurs fundamentally express themselves to customers?

It is marketing at this point. Luckily, social media enables you to do that in a fast, free, and ubiquitous way. You really can’t spend money on social media unless you really try. Social media is really more about effort than expense.

FTP vs HTTP

18 Nis

Both protocols are used for uploads and downloads on the internet, for text and for binary, both over TCP/IP. But there are a lot of differences in the details:

Transfer Speed

Possibly the most common question: which is faster for transfers?

Given all details on this page. What makes FTP faster:

  • No added meta-data in the sent files, just the raw binary
  • Never chunked encoding “overhead”

What makes HTTP faster:

  • reusing existing persistent connections make better TCP performance
  • pipelining makes asking for multiple files from the same server faster
  • (automatic) compression makes less data get sent
  • no command/response flow minimizes extra round-trips

Ultimately the net outcome of course differ depending on specific details, but I would say that for single-shot static files, you won’t be able to measure a difference. For a single shot small file, you might get it faster with FTP (unless the server is at a long round-trip distance). When getting multiple files, HTTP should be the faster one.

HTTPS Is More Secure, So Why Isn’t the Web Using It?

20 Mar

You wouldn’t write your username and passwords on a postcard and mail it for the world to see, so why are you doing it online? Every time you log in to Twitter, Facebook or any other service that uses a plain HTTP connection, that’s essentially what you’re doing.

There is a better way, the secure version of HTTP — HTTPS. That extra “S” in the URL means your connection is secure, and it’s much harder for anyone else to see what you’re doing. But if HTTPS is more secure, why doesn’t the entire web use it?

What is 3GPP?

03 Mar

The 3rd Generation Partnership Project (3GPP) is a collaboration between groups of telecommunications associations, to make a globally applicable third-generation (3G) mobile phone system specification within the scope of the International Mobile Telecommunications-2000 project of the International Telecommunication Union (ITU). 3GPP specifications are based on evolved Global System for Mobile Communications (GSM) specifications. 3GPP standardization encompasses Radio, Core Network and Service architecture.[1]

The groups are the European Telecommunications Standards Institute, Association of Radio Industries and Businesses/Telecommunication Technology Committee (ARIB/TTC) (Japan), China Communications Standards Association,[2] Alliance for Telecommunications Industry Solutions (North America) and Telecommunications Technology Association (South Korea).[1] The project was established in December 1998.

3GPP should not be confused with 3rd Generation Partnership Project 2 (3GPP2), which specifies standards for another 3G technology based on IS-95 (CDMA), commonly known as CDMA2000.
