Facebook f8 2007

1 year, 7 months ago.

I came across with this video when I was checking out the Facebook API.

I think he looks nervous, somewhat at the time…..even though there were stories of how he overslept the meeting with Yahoo! last year, but there is nothing to blame.

Internet Password Security Level

1 year, 8 months ago.

I recently updated my Facebook password because my password was reset by Facebook for some unknown reason. This incident alerted me of security levels of my passwords. I was pretty much using the same passwords for many of my most important emails but also on some doubtable websites, even though they all claim they will not share registration information with anyone else.

Risks

  • Increasing number of phishing sites. Phishing refers to websites which mimic designs of some popular website and asks users of the authentic website to “log-in” to the site. They would then store the credential and use them for malicious purposes;
  • Increasing risk of cross-domain scripting attack. Along with the exposure of Ajax, cross-domain-scripting has gained more power and browsers can be tricked to send cookies of some domain to illegitimate domains, exposing important information in cookies to third parties;
  • Reusing same id name across all websites. In the past few years many specialized web applications have been built and the Internet has become more heterogeneous. These new web apps offers service like no others. Even though they all provide APIs for other people to access their function, up to now, users still need to have register at all places. Keeping user names consistent is certainly what most people would like to do during registration. Therefore, if someone has gained the username and password pair of someone from one site it uses, it can be reused, sooner or later, on some others, or at least, as a great heuristic guess.

The Plan

To guide myself in choosing password during registrations, I’ve created the following diagram to show the level of seriousness in selecting password strength for different accounts on the web.

Remote Desktop Chaining

2 years, 12 months ago.

There was a meeting today but I wasn’t able to get to my office before meeting starts, and so I decided to connect to my remote computer from home to attend the meeting. Soon I realized that I chained four computers by “remote desktop”-ing from one to another. Here are the details:

 

Notation:

  • Computer A – Laptop at Home
  • Computer B – Desktop at Home
  • Computer C – Desktop at Office
  • Computer D – Laptop at Office

Facts:

  • I didn’t bring D home last night
  • My home phone is far away from B
  • VPN is installed on B, but NOT on C

Limitations:

  • To connect to C remotely, I must have VPN client installed
  • To connect to D using remote desktop, I must be from intranet
  • The meeting requires D and any phone

Solution:

  1. 1. I dialed VPN from B connect to C. But I realize that I cannot reach the phone from B;
  2. 2. So I turned on A positioned close to the phone, and connect to B with Remote Desktop. Next I found I actually need to connect to the meeting server from D;
  3. 3. From A, in the Remote Desktop window connected to B, I tried to open another Remote Desktop connection to D. But D only accepts request from intranet and thus B’s request is rejected;
  4. 4. From A, in the Window showing B, I connected to C using Remote Desktop;
  5. 5. From the Remote Desktop Window just opened on C, connect to D using the third Remote Desktop.
  6. 6. To make it worse, we actually used net meeting for screen sharing and so I was connected to another Desktop from D.

Have some FON – WIFI 2.0!

3 years, 1 month ago.

This is something everyone should check out – the incredible global WIFI coverage, powered by you!

Recently it’s in celebration of its 1st anniversary and so it’s giving out free 54M routers. So you’ve got absolutely no risk to try it. And how it works is simple, plug it in to allow other foneros (acronym for FON users) use your wireless when they are visiting your neighborhood, and most most important and fun is you will be warmly welcomed wherever you go by other foneros.

Let me just summarized things up and you make the decision. No tricks or exaggeration.

Stop! What is this thing good for?

It’s a get-and-share spirit. Once you joined the community, wherever you are at, Europe lets say, and there are Foneros living around, go ahead and connect to it! So you are not stuck even when you are touring small towns abroad, as long as the town has one Fonero!

What you do to join Fon Community.

Request a free La Fonero Router now / Buy one later.

What do you need to get the free router?

Nothing but a valid address. No tax, No shipping fees. It doesn’t ask for your credit card at any point of the check out process.

If you are not quick enough to get a free router, you are not joining?

Yes, I would say 90% people will leave and check back later if the free deal expires. But, check back soon. The usual price is around $5 – $10 with applicable tax and shipping. It doesn’t quite look like a for-profit community. If $20 dollars for a stylish 54M wireless router doesn’t scare you away, read on!

I know they charge me for hell a lot random things once I got it! I got it and I can’t back out!

Not right. The worst thing can happen to you is you are requested to pass the router to a friend who would like to share his bandwidth. No operation fee, service fee, or any other names companies created to charge you for.

There is no free lunch? It’s so great that I can hardly believe ya!

No, no free lunch. You do need to spare some wireless for your visitors when they need Internet access. But, you have controls over how much bandwidth you’d like to give visitors. And remember how kindly they are to you.
