I like to hack on stuff. I work at Google.

oscardelben··on I’ve given up using soap & shampoo forever
I think the point of the experiment is to get rid of all chemicals. Like for shampoo, you don't know what the effects of the conditioner are, and what would happen to your hair.
oscardelben··on Plea HN: Any work?
Start keeping track of where your money are going. I use a notebook for that, and I have categories like clothes, eating out, food, business, etc. I record all expenses and after a while you become more conscious of your expenditures.
oscardelben··on Google's Current Bid for Groupon: $5 Billion.
I suspect at this time Groupon would be a better business model.
oscardelben··on Workflowy is to TODO as git is to svn
I did the same, and it's proven very useful so far. I also started to use it as my journal.
oscardelben··on Quick puzzle: how long to get to heaven?
Thanks!
oscardelben··on Quick puzzle: how long to get to heaven?
This is how I solved it before looking at the answers:

I calculated that from a scale of 0 and 1, we have a 0.33 chance of going in in 0 days.

The probability of going in within 1 day is equal to the probability of choosing the second door (0.33) multiplied to the probability of choosing the first door the second time (0.33). 0.33 * 0.33 is equal to 0.1089, so we have a 10% chance of getting in with 1 days.

To get in in 2 days, we would have to choose the second door, and then the first door. Again, this is another 10%

At this point I thought that we have a 53% chance of getting in within two days (33% + 10% + 10%), and 47% of getting in with more than 2 days.

The probability of getting in within 3 days is 0.33 * 0.33 * 0.33, which is around 3%. Considering that the probability of getting in within 4 days would be 1% (0.33 * 0.33 * 0.33 * 0.33), I somehow imagined that of the remaining 47% of chances of getting in within more than two days, the 75% was represented by the probability of getting in within 3 days. The 75% of 47% is 35.2%, which is slightly higher than the chance of getting in within 0 days. The answer is 3.

Given that I lack math background, I wonder if my way of solving this problem is correct (hopefully someone can follow my reasoning).

oscardelben··on WorkFlowy (YC S10) launches a better way to organize your brain
That, and because it's extremely fast compared to other software. I usually tend to go with less apps, but this could be a nice addition for me. Time will tell.

I thought about that, but given its potential for me I set it as my homepage. I'll give it a few days to see if it has money for me.
oscardelben··on Having big goals and stating them proud
I guess it depends on people. For me announcing goals make them a lot more likely to happen. Also, from what I remember about that TED video, the studies were not really convincing to me. Anyway, see what works for you, that's what's important.
oscardelben··on Entrepreneurship in Italy from a non-Italian’s perspective
I don't know, I work for a startup funded by them, but I have no idea about that. It's still something if you live here and you need funding.

If you want to start a startup in Italy, checkout h-farm, which is a startup incubator near Venice.

Thank you, that does make sense to me indeed. I'll stick with your advice.

I've read the mythical man month already. I've not yet read the C programming language though.
oscardelben··on Youtube Live Epic Failure (Plaintext DB Password Exposed)
That's why you should never expose tracebacks in a production environment. But plain text? Really?
oscardelben··on Interesting TED Videos
The discussion usually happens in the comments, both here and on the site, like how is happening right now.

I think the real value is indeed in the discussion that is being generated after you've consumed an online resource, and I think this is the reason why we have comments here.

I thought that these videos could be helpful in some way for some fellow hackers and that's one reason why I posted the article here.

Another reason is that I'm genuinely interested in knowing about other related videos by reading the always interesting discussions here. I'm also trying to add all these contributions to the post as well.

You may be right about the fact that all these videos have been posted here before. I honestly don't remember about all of them but again I hope they can be useful to someone.

oscardelben··on Posterous is being DDoS'd
Thank you
oscardelben··on Posterous is being DDoS'd
Maybe, and take it with a grain of salt, some people got infuriated by their recent switch to posterous campaign. I know this may be a very remote option, but in my opinion it's very possible.

I don't have a TV.
oscardelben··on Not having a cell phone means that the world has to run on your time
I moved to a new country one week ago and I thought that I would have needed a new sim card for my cellphone. To my surprise, after a week I still see no reason for having a cellphone with ne. I feel more free now and I'm not sure I'm going to use a cellphone anytime soon.
oscardelben··on Ask HN: List everything you know that is good/bad for our brains.
Unless you live with no tv and you check them 10 minutes daily to keep yourself informed of what's happening in your industry (i.e. they're not an addiction).
oscardelben··on Meat based diets made us smarter
I don't want to be right yesterday, so thanks for that link. I agree that the book contains lots of promotion, but it still helped me a lot in understanding the role that nutrition has in our lives. My take home from that book is that eating a lot of processed foods and meat is harmful, and it's better to eat whole foods instead, mostly plants.

Edit: I'm not a vegetarian by the way.

oscardelben··on Meat based diets made us smarter
Organic meat may be good in small doses. However most of the meat today is not the same as it was centuries ago. The book "The China Study" does a good job at explaining the diseases caused by meat.
oscardelben··on Ask HN: How do you know when you are an expert?
Four stages of competence[1]:

* Unconscious Incompetence: The individual neither understands nor knows how to do something, nor recognizes the deficit, nor has a desire to address it.

* Conscious Incompetence: Though the individual does not understand or know how to do something, he or she does recognize the deficit, without yet addressing it.

* Conscious Competence: The individual understands or knows how to do something. However, demonstrating the skill or knowledge requires a great deal of consciousness or concentration.

* Unconscious Competence: The individual has had so much practice with a skill that it becomes "second nature" and can be performed easily (often without concentrating too deeply). He or she may or may not be able teach it to others, depending upon how and when it was learned.

oscardelben··on WordPress Theme Thesis Maker Backs Down, Adopts GPL
It gives you an area in your admin panel where you can custom functions, change the colors, text settings and layout. It also gives you the ability to customize the css. You still need to hire a designer if you want to differentiate it from other people, unless you're happy with the default.

It's not for creating multiple google profiles, but for finding google profiles of other people.
oscardelben··on Ask HN: Programming books that are more like math books?
For general programming concepts, there are many books with exerices, like sicp, essentials of programming language, etc. For books about specific programming languages, there are many quizzes online that you can use, just search for "language quizzes". Also project euler and similar websites may help.
