There are some apps that let you block sites effectively for a block of time (like selfcontrol for mac), but I didn't see any that monitor your daily usage and then block the sites. (Though various extensions do that.)

Most of those reasons seem exaggerated, except one: News wastes time. It's just to easy and effortless to click on news stories and bam - there goes 45 minutes of time. Does anyone know a good program that blocks you from e.g. wasting more

By the time they get around to de-regulating the medallion system, self-driving cars will be available, which will put taxi drivers out of business. (Unless they block that too.)

Nice. Between Jetstrap, Divshot, and Easel, there's no shortage of WYSIWYG Bootstrap apps. The question is which one will offer the best options for creating code for an actual dynamic website. I.e. it would be great to use something to do

They link to a paper which states that sorting benefits both high and low-performing students. However, it helps high-performing students more, which may explain why sorting has been unpopular in the last few decades. People are so into 'eq

Cool. For this course, they monitor changes on the browser side to see what you do to the page. I think this is an effective way to teach people how to use applications. It actually reminds me a bit of RibbonHero, a project Microsoft once d

While I basically agree with this article, it mainly added some stronger opinions to an Atlantic article from 1982. It didn't discuss synthetic/cultured diamonds, which recently became available at 'low' prices. DeBeers needs to convince pe

This is good news. Publishers charge US students much more than students in other (even high-income) countries. At least they shouldn't be able to legally prevent people from buying international edition books. The publishers often change t

If a site like StackOverflow/Github had a more powerful search, better semantic data, etc. maybe people would be able to create things primarily by searching through it? In this example, one would type "sort array" and it would auto-find a

"Over the next 100 years, the importance of creativity will trump systems thinking due to the rapidly escalating power of computers." Right, because more technology has always led to less demand for math/technical skills. And where are the

Its silly to criticize them for rates under 20% since many people sign up just to see what it's like without actually planning on finishing it. What would be more relevant is to see what percent of serious committed students finish a course

Google thinks doioig.gov is StackOverflow.com. See what happens when you do a search for info: http://www.google.com/search?q=info:stackoverflow.com Note what site shows up as the result and for the links for "similar" and "link to".

If you have your own domain, you can always export your blog to another service, so what's the big deal? Also, if you want a reliable hosted service, you can always use the free Wordpress.com or Blogger instead of some new startup's offerin

You can just use free services to host your wordpress blog without any trouble. Set it up on AppFog or OpenShift, use cloudflare too, and use a cache plugin if needed. I don't think any HN-effect could take that down.

Many people learn peck-typing and then find it difficult to switch to touch typing since its initially slower. It would be cool if someone could create a program that tries to get people to learn typing as them type real things they would b

It would be good if a program let you view each sentences history on its own, so you could see different alternatives without needing to change the whole document.

Not everyone gets the most expensive product or service. Shouldn't people be able to get cheaper lawyers? Why don't some of the unemployed lawyers create budget practices? No person or business would be willing to use them?
