The crossroads of life and tech

Super web colour picker — AllScoop.com

I was helping Raul out with a CSS issue tonight and pointed him toward a colour picker that I’ve used a number of times for my own projects.

The tool features the full range of hex-code colours but breaks them down into three categories:

  • Web-Safe – The 256 “safe” web colours
  • Web-Smart – An extended range of colours for most browsers
  • Unsafe – The remaining colours which will work fine for applications, but aren’t necessarily suitable to the web.

Colour Picker

The colour picker itself is a nice basic version based on DHTML and a images. I like this because it makes the tool accessible to more platforms by not requiring Flash or Silverlight or some other complexity that simply isn’t required.

As an added bonus, there’s a downloadable version of the colour picker, which again just consists of the one HTML page, and the PNG graphic which shows the colour wheel.  This is a great addition.  (Note: some browsers don’t like you to use offline javascript, so you may need to approve the offline version from a warning bar.)

The page is hosted by AllScoop Technology and I have to admit, until tonight I never bothered to look at the rest of the site.

As it turns out they’ve got a ton of great resources so don’t be surprised to see more of their stuff featured here, or on the AGP in the future. :)

Low-Hanging Ruby Eclipse

I couldn’t resist posting this one when I discovered it last night while researching the post about Simeis 147. This photo was taken from the Mall of Asia in Manila and is of the moon sneaking in front of the sun just before sunset.  I’ll let the stunning imagery speak for itself.  As always, photo is courtesy of APOD.

I even sent this one to my wife. :)

What Does a Supernova Look Like? — 1859!

Occasionally on the blog I like to post an image from APOD which gets my attention in some way.  I used to do this far more regularly, but things have gotten in the way the last couple of years.  I’m going to make an effort to post at least one of these per month.

I’m already late with the January entry, but here it is nonetheless:

Simeis 147: Supernova Remnant

Simeis 147: Supernova Remnant

Looking at this nebulous form gives you some idea of the power generated by a star as it collapses in on itself and sends matter spewing off in all directions toward parts unknown of our universe.

The width of this monstrous formation is 150 light years, or over 9.8 Million times the distance between our Sun and the earth. Kinda makes you think… When the light you see from this nebula this year began it’s journey toward Earth it was the year 1859 and the following notable activities took place:

  • Sir Arthur Conan Doyle is born
  • Ground was broken on the Suez canal
  • A Tale of Two Cities is published
  • Charles Darwin publishes On the Origin of Species

So give a thought to history the next time you stare out at the cosmos.

Tweet Tornado: The Path to 1 BILLION Tweet Spam

The Internet is a wondrous place where we can connect with people from all over the world as easy as our neighbour next door, or some would say more easily.  Tools like email, instant messaging, blogs, podcasts and social media sites like Facebook, YouTube, Flickr and the subject of this post: Twitter.

Twitter’s ability to instantly broadcast a message to dozens or hundreds of your closest friends makes it an ideal tool for sharing information with those who are interested in what you have to say.  In recent months it has also become the domain of Internet marketers searching for another channel to hock their wares.  Some do it simply, organically by browsing Twitter for people who may be interested in their product or service. This method I don’t have a problem with.  There are others who would use automated services or bots to handle this process and this is where it starts to bother me.  Enter Tweet Tornado.

The Software is the Problem

This is the kind of product that may not be illegal, but certainly goes against the spirit of the Terms of Service of sites like Twitter.  In fact it enables people to explicitly break terms 4, 7 & 8 of Twitter’s ToS. Tweet Tornado’s creator(s) have created software which allows people to create an unlimited number of tweet-spam accounts that can be used to spam innocent Twitterers with that company’s product or service.

On Tweet Tornado’s site the how-to video speaks to some of the less-than-savoury spammer practices such as:

  • Creating accounts using fake email addresses
  • Using pictures of “hot chicks” to garner more followers
  • Using a screen-scraping technology to auto-follow pretty much anyone contributing to the public timeline

With the stability problems that Twitter is already having the practices that this software promotes and enables need to be shut down or at the very least severely curtailed.

Lets just consider this scenario: 50 people were to purchase this software and each register 1000 accounts (completely feasible considering the methods employed) Each of those accounts were to aut0-follow 20,000 people and get a 10% follow-back rate.  Each of those spammers sent out 10 messages per day through each of their accounts Twitter would need to relay a staggering 1 BILLION tweet-spam messages.

50 x 1,000 x (20,000 / 10) x 10 = 1,000,000,000

So let’s stop the bullshit before it starts.  Twitter needs to take proactive measures to explicitly forbid this type of practice, and if necessary put in place the necessary legal safeguards to protect their servers and their systems from the DoS attacks and QoS degredations we’re likely to see.

Protect Our Tweets!
