manglav··on Ask HN: 12 year old tech savvy girl – books, programs, events, advice?
I've taught many children, and the biggest motivation for them was tangible success. Project based learning combined with a good teacher will do absolute wonders. Eventually, she can show off her projects ( for example, a M & M color sorter) to her friends. Maybe her friends are interested too and that will give them a little encouragement to pursue their interests as well! Let me know if you have any other questions.
manglav··on Ask HN: I have developed bedsheets that can go months without washing
good stuff, polymers are great for that sort of thing. Even though polymers abrade over long periods of time, it sounds like your product should be licensed. Get some hard data, and license it to clothing companies / fabric companies, that's the easiest way to get your product to market.
manglav··on Ask HN: I have developed bedsheets that can go months without washing
1. Implanting gold or silver molecules in clothing has been done for at least 3 years now.

2. They've found over long periods of time, the molecules get transferred to the body, which can be problematic.

3. Smell is more of an issue than cleanliness.

manglav··on Perfectly centered break of a perfectly aligned pool ball rack
Agree on the spin, I was assuming a perfectly vertical break.

Abou the burn marks, see here http://www.pooldawg.com/article/pooldawg-library/table-maint...

Yeah, I hate it when the ball pops up, but my opponent looks cool catching it, heh. I also play pool. Best game for lounging I feel.

manglav··on Perfectly centered break of a perfectly aligned pool ball rack
While this is great for a theoretical model, most professionals also try to put forward spin on the cue ball, to offset the collision and break apart the rack further. You may have noticed small white burn marks from the heat generated by the cue ball spinning on the felt, from the location where most people break.
manglav··on Ask HN: Do you hire developers from bootcamps?
Why don't you train one or two and take a percentage of their salary? That way, they don't pay up front, you prove your hypothesis, and companies get more employees. Everyone wins. Also, try not telling people upfront that you did a bootcamp, there is no net benefit (some companies refuse to hire from them, and others are like 'meh').
manglav··on Former BP geologist: peak oil is here and it will 'break economies'
I don't understand your comment.

1. How can oil "only" get so expensive? By oil, we are referring to the act of gathering existing oil. There is no limit to the cost of gathering. Going deeper and deeper, or from lower concentration will become more expensive as time goes on.

2. We have a lot of alternative sources of energy that put a lid on oil price. Can you explain the mechanism for this? Are you referring to the true cost of oil, or just at the fillup station? Are you saying the major cost of gathering oil is the input energy, and because the input energy is alternative, the EROIE is infinite? Please elaborate.

3. making artificial oil out of coal will become viable on a large scale. Making artificial oil has nothing to do with gathering oil. The reason they did that was that oil was a more valuable energy medium than coal, because it can be used for many products, not just trains/ships/electricity.

4. There's always nuclear power. I am a big fan of nuclear power, but have no faith in governments making a sound scientific analysis. So unless nuclear power becomes cheap (infrastructure-wise), I think peak oil is still a big concern.

5. Lot's of oil at sea we haven't explored. There's a reason we haven't explored it - it costs way, way, too much. But I'm sure we will as the EROIE goes down.

manglav··on Former BP geologist: peak oil is here and it will 'break economies'
This is quite scary when you think about the fact that so most economies are ultimately tied to their oil prices (except Greenland). Because peak refers to production, as the world goes, we have some more time to prepare, but price will increase in the meantime. What's interesting is that I'm more hopeful that the oil companies will find a common ground solution than the governments of the world will, because at least the companies are motivated by their collective wallets.
manglav··on India Re-criminalizes Homosexuality
whoops, sorry about that. If I could delete I would. Please ignore.
manglav··on Looking for Real Problems/Examples to Help Learn JS
I fail to see how that fact changes anything. Ruby is literally so easy in terms of syntax, that you can teach the concepts in ruby, and "port" them back to js.
manglav··on Looking for Real Problems/Examples to Help Learn JS
I'm confused. Have you searched google for javascript koans? I'd link you, but it's literally the first one...

Also, I don't think javascript is a good first language. A first language's syntax should get out of the way, allowing the concepts to take root. It's also very hard to determine what is good javascript. Classes aren't really present there either. I'd suggest ruby, and teach the fundamentals, then introduce to js.

manglav··on Ask HN: I just dropped out of college, should I do a coding bootcamp?
Why don't you try getting an internship? Don't mention to companies that you've dropped out, just say you're taking a break to focus on personal development or something. After the internship, you should be able to get a job. I don't recommend doing a bootcamp if it will significantly deplete your cash. If you have around 6 months of expenses saved up + the fees for the course, then go for it! App Academy does not have an up-front charge as well, so it sounds perfect for your situation.
manglav··on Nobody builds nuclear reactors for fun anymore
There is a company trying to model it by 2015. Check FLiBe Energy out.
manglav··on Ask HN: I have 10,259 Fortune 500 job listings. What should I do?
Dropbox? I don't know if it would be commercially valuable unless you gave analytics with it. I know I would be interested in it, but I'm not sure I would pay for it.
manglav··on Processing Hour of Code
Wow, his teaching style is amazing. I only know a few people who can make me so excited about something like that. It's definitely a personal goal for me to be able to teach that effectively.
manglav··on Ask HN: where do you backup a ton of photos?
How much would you pay for a nice UI wrapper, and the ability to designate glacier photos vs. S3 photos?
manglav··on Ask HN: How do you backup 200TB across 15 servers onto a single 50TB server?
Have you looked at FlexRAID? I am not too knowledgeable on the depths of this topic, but I know it can back up over SMB/FTP. It's a very interesting engine as well, and if you decide to roll your own, you might get some inspiration.

manglav··on What I learnt bootstrapping my startup from Thailand for six months
I'm actually in the market for an apartment starting next month...if you'd like to email me I'd be happy to discuss with you. username at g
manglav··on Ask HN: Bootcamps
I guess it depends on what you mean by "learn to program". Are you just script hacking, and trying to get something working for a personal project? Are you delivering code that people have to depend on? Are you trying to sell your skills?

I am doing App Academy, and I think it will be very worth it. It gives you a great network of people in the industry, solid skills and accepted practices, and most likely a job (if you want). It's tough to do all of this on your own in the same amount of time.

manglav··on [dead]
Designer or developer?
manglav··on Nitrous.IO is now in public beta
I'm not exactly sure why it's so expensive, but it's not like you will need it. The whole point of Nitrous.io is that it's a cloud ide. Unless you are deploying a huge app (and if you're deploying a huge app, you probably don't need a cloud IDE), you won't touch it.
manglav··on Ask HN: Data Scientist/Analyst jobs at environment or wild life organizations?
What are you expecting in terms of compensation? Remember, most of the time these organizations are operating on sparse budgets. It would need a lot of actionable discoveries for an organization to see the benefit of having one on staff. I do know that the New York Times started a new department for this. You should try building something with their very cool API and send something over.
manglav··on A Grumpy Assessment to the Most Beautiful Equation (2011)
I'm sorry, but can you elaborate? It kind of went over my head, and I would love to learn something new. What do you mean by the number theory/no accident comment?
manglav··on A Grumpy Assessment to the Most Beautiful Equation (2011)
I liked your breakdown. I think without linear algebra, it's not very intuitive that it's simply a rotation, and the power series itself is quite interesting. So to most people, without a high level of mathematics to discern each component, it's the combination using all of the constants together in one equation.

Just curious, what is your favorite/most beautiful equation? Fractal geometry? (just guessing...)

manglav··on How Michigan took hackathons by storm.
I'll throw in my experience. I went to PennApps Jan 2013 after I learned some HTML, CSS, and javascript with some new friends I made. While we didn't associate with Michigan Hackers, we saw the rise of the facebook group, and their "recruiting efforts". They killed it. Fun stuff on the diag(the quad), awesome hack nights. It was sort of a focal point - a bright light to hacker moths, who were always around, but didn't have a community. Mhacks is definitely a force to be reckoned with, and a large part of my first steps towards software development.

Also, MPowered is our university entrepreneurship club. In my experience with them, it is mostly filled with business people trying to find software guys to build their stuff for them. However, apparently there is an incubator that has most of the people that actually build, but I never saw them too much.

Go Blue! Can't wait to see what they will do next year.

manglav··on The house I was born in sold for $4000
tangent: can I email you? I'm moving to SF in September and trying to conserve my funds, and it seems you know the area quite well. I'd be happy to buy you a drink in exchange for your time.
manglav··on Not Having A Real Job
I didn't get the same feeling as you. I received it with quite a bit of warmth, with a little bit of wistfulness? Try picturing Gandalf saying the words.

What did you do for volunteering? I'm sure each type has their pros and cons. For me, I once volunteered to help abused children. One of our activities was to help them create a board filled with drawing of people that they can trust. We went through it with all the kids afterwards, adding where they can find them. Helping, no, empowering those kids was the most fulfilling feeling I've felt, and this was almost 7 years ago (I'm 22).

Unfortunately, I haven't traveled (world trip coming after I can freelance), but I hope that it will reveal more about myself as a person as I put myself into new situations across the world.

manglav··on Announcing Online MS in Computer Science in Collaboration with Georgia Tech
Heh, about as expected. I can get to the final interview no problem, but I always fail when they ask the "basic" technical questions, such as "How does a garbage collector work?" and "How would you populate a binary tree?". My one formal class of C wasn't enough to cover those topics.

However, I am enrolled in App Academy, so I can start doing web dev. My advice is to show you've taken at least an Algorithms/Data Structures course, that plus the skills you've picked up from programming on the side should be enough to get a junior dev position.

In terms of a job that combines both fields...the closest thing I know to a software person in ChemE is an Aspen Troubleshooter for Exxon. Personally, I want to do advanced controls and modeling/simulation. Can I shoot you an email? I might have a lead for you with Tesla.

manglav··on Announcing Online MS in Computer Science in Collaboration with Georgia Tech
I'm so happy to see this - it's a sign of progress of the education system, and it gives me so much relief to see that someone gets it at the top of the education totem pole. I discussed this with a master's degree student a few years ago, because the cost (especially for computer science, no labs) seemed too low to ignore. I will sign up for this as soon as possible.

Also, having a master's in Comp Sci will really help me have a shot for all these software eng. positions I keep applying to as a chemical engineer.

Can anyone tell me how Georgia Tech ranks/is thought of for Computer Science? I know the article says "among the best", but I would rather ask HN.

manglav··on Where to buy an online business?
Yes, actually less than 30k a year. My budget won't allow for anything more. In a rare case, a higher revenue business may be of interest. Please email me if you have anything.
