alonswartz http://stuff.alonswartz.org random stuff just for fun... posterous.com Sun, 10 Apr 2011 09:38:00 -0700 Why I stopped using Posterous http://stuff.alonswartz.org/posterous-is-dead-to-me http://stuff.alonswartz.org/posterous-is-dead-to-me

Firstly, if you're subscribed to my "stuff" via Posterous, its been moved to http://www.alonswartz.org/stuff/. This is my last post on Posterous, so please re-subscribe via RSS or email.

I really liked Posterous, and tried to move my full personal website to the service, but I just couldn't. I felt too constrained, took too much time, and couldn't do what I wanted without implementing stupid hacks. Eventually, I gave up.

Reasons why I made the move:

  • It's too slow. Loading this Posterous with 5 posts takes 18 seconds vs. 4 seconds on my new site (before optimizations).
  • Custom theming is too time consuming, and requires a different server for theme images.
  • Embedded javascript is not supported. It's been talked about and promised for ages, just hasn't happened (yes, I know you can use iframes).
  • Web-posting doesn't support markdown, or a preview option. Editing a posts styling is pain.
  • There is no way to display auto-generated recent or popular posts.
  • Post and page slugs can't be changed, ever (this post is an example of that).
  • Page URL slugs require the /pages prefix.

Don't get me wrong, Posterous is really useful if you post via email which is what it was designed for, and the reason I started using the service. But in reality I rarely used the email feature as it didn't make sense for my use case.

I hope Posterous will fix these issues in future, but for now I just want to say thanks.

Mon, 21 Feb 2011 03:47:00 -0800 Brain Teaser: 100 floors, 2 orbs http://stuff.alonswartz.org/brain-teaser-100-floors-2-orbs http://stuff.alonswartz.org/brain-teaser-100-floors-2-orbs

You have two identical crystal orbs. You need to figure out how high an orb can fall from a 100 story building before it breaks. You know nothing about the toughness of the orbs: they may be very fragile and break when dropped from the first floor, or they may be so tough that dropping them from the 100th floor doesn’t even harm them. 

What is the largest number of orb-drops you would ever have to do in order to find the right floor? (i.e., what’s the most efficient way you could drop the orbs to find your answer?) 

You are allowed to break both orbs, provided that in doing so you uniquely identify the correct floor.

 

Spoiler alert - See the solution.

Wed, 05 Jan 2011 22:57:00 -0800 I spread your idea because... http://stuff.alonswartz.org/i-spread-your-idea-because http://stuff.alonswartz.org/i-spread-your-idea-because

Ideas spread when people choose to spread them. Here are some reasons why:

  1. I spread your idea because it makes me feel generous.
  2. ...because I feel smart alerting others to what I discovered.
  3. ...because I care about the outcome and want you (the creator of the idea) to succeed.
  4. ...because I have no choice. Every time I use your product, I spread the idea (Hotmail, iPad, a tattoo).
  5. ...because there's a financial benefit directly to me (Amazon affiliates, mlm).
  6. ...because it's funny and laughing alone is no fun.
  7. ...because I'm lonely and sharing an idea solves that problem, at least for a while.
  8. ...because I'm angry and I want to enlist others in my outrage (or in shutting you down).
  9. ...because both my friend and I will benefit if I share the idea (Groupon).
  10. ...because you asked me to, and it's hard to say no to you.
  11. ...because I can use the idea to introduce people to one another, and making a match is both fun in the short run and community-building.
  12. ...because your service works better if all my friends use it (email, Facebook).
  13. ...because if everyone knew this idea, I'd be happier.
  14. ...because your idea says something that I have trouble saying directly (AA, a blog post, a book).
  15. ...because I care about someone and this idea will make them happier or healthier.
  16. ...because it's fun to make another teen snicker about prurient stuff we're not supposed to see.
  17. ...because the tribe needs to know about this if we're going to avoid an external threat.
  18. ...because the tribe needs to know about this if we're going to maintain internal order.
  19. ...because it's my job.
  20. I spread your idea because I'm in awe of your art and the only way I can repay you is to share that art with others.

Tue, 23 Nov 2010 07:35:00 -0800 Filtering Thunderbird for Starred Mail http://stuff.alonswartz.org/filtering-thunderbird-for-starred-mail http://stuff.alonswartz.org/filtering-thunderbird-for-starred-mail

This little tip just changed my life… I swear. I've been looking FOR-EV-ER for a way to filter my Thunderbird Inbox so that I see only the "starred" messages. Despite my poking and prodding and searching I couldn't figure out how until today.

When you're building your filter/custom view/folder criteria, "starred" is not an option in the first drop down (like Flag, Tags, and Junk Status are). Additionally, despite the fact that the mail server knows all about whether a message is "starred" or not, it's not in the header of the email either

In Thunderbird, Starred is a STATUS!

That's right, a STATUS. Drop the first box down and select "Status", drop the second box down and select "is", then drop the third box down and select "Starred". That's it, you're done.

Tue, 31 Aug 2010 11:11:19 -0700 I'm going back to school - Khan Academy style http://stuff.alonswartz.org/im-going-back-to-school-khan-academy-style http://stuff.alonswartz.org/im-going-back-to-school-khan-academy-style

The Khan Academy is a non-for-profit with the mission of providing world-class education to anyone, anywhere. Despite being the work of one man, Salman Khan, the 1600+ video library is the most-used educational video resource in the world (as measured by YouTube video views per day and unique users per month).

I'll be starting with one of my favourite subjects (outside of technology) which is biology and will probably then move onto organic chemistry and then physics.

For fun, I might dabble a little in Linear algebra, probability and statistics - we'll see...

I highly recommend Khan - give it a shot...
