leeHS··on Ask HN: What Do You Want?
Is it the best place? I question that.

Post this same message at a group of researchers, elementary school teachers, chefs, women, kids. I'd be curious how they would answer this question.

There is just so much out there by hackers, for hackers.

My 2 cents.

leeHS··on Show HN: We're 2 engineers and we've built product search better than Google's
Hey there! So I took it for a spin. I entered "bike brakes" since you use this as an example in your "About" page, but nothing came up within a 50 mile radius.

Maybe because I'm in Toronto? But if that's the case, perhaps you should have an "only works in the US" message pop up once your geolocation sees that I'm outside the country.

Since you mentioned google, I ran the same search on google maps, and all kinds of stuff came up for bike brakes. Now, much of it was noise, which is what your product is likely designed to deal with, but at least I got something!

From a design standpoint, looks clean and clear. Easy to navigate.

Best of luck! Hope it takes off.

Wow, how did I miss this?

Thanks for the heads up.

leeHS··on RoR
Good point!

I should also point out that there is this on going debate about whether it is better to learn Ruby before diving into Rails, or just learn them at the same time. Personally I tackled them both, since I could plug what I was learning into a web application project. I learn much better by doing.

Hope this helps!

Why`s Poignant Guide: Classic and rather odd Ruby guide. I especially enjoyed this resource, and the crazy stories really helped make things sink in. http://mislav.uniqpath.com/poignant-guide/

Mr. Neighborly’s Humble Little Ruby Book: Another Ruby guide. I really recommend this one. The information is laid out really well and I found it very easy to read. http://humblelittlerubybook.com/book/hlrb.pdf

Rails for Zombies: This was my first dive into Rails. They are basically instructional videos with interactive labs at the end of each tutorial. I spent a long time doing these tutorials, pausing frequently to google stuff I didn’t fully understand. http://railsforzombies.org/

Ruby on Rails Tutorials, by Michael Hartl: The most comprehensive of the resources listed so far. Again, I took my time working through this one, and it really paid off. http://ruby.railstutorial.org/ruby-on-rails-tutorial-book

Agile Web Development With Rails: But I’ve only just order it! This is the resource everyone seems to recommend. It’s also the only one I’ve had to spend money on so far. Not finished it yet, but so far so good. http://www.amazon.ca/Agile-Web-Development-Rails-Ruby/dp/193...

leeHS··on How does biology explain the low numbers of women in computer science
I'm male. My field is Forensic Science. It consists of about 80% women. Doesn't matter which lab I go to, or which forensic education program I visit, the percentage stays the same.

Why?

On a daily basis I'm dealing with very violent crimes. Why does this sort of work appeal to women more than men?

leeHS··on Arson Forensics Sets Old Fire Myths Ablaze
I'm a Forensic Biologist, working mostly on DNA evidence. This article does not surprise me in the least. The National Academy of Science is also not surprised. They issued a report about a year ago examining the forensic sciences in the US and found that many fields do not have enough core research. My favorite example is blood spatter analysis (think Dexter). This field is completely built around crime scene experience. It's only been within the last decade that some serious research has been undertaken to provide a scientific basis for the opinions offered in court.

Now, it's not bad if your particular field has a few areas that are still lacking in basic research. But you have a DUTY to express this in court. For example, in this case, the expert can say that based on his 40 years in the field, this is his opinion, but he should note that there is no scientific support, and he should always declare if there is any disagreement within the community.

Forensic science is an amazing field...unfortunately the practitioners tend to mess it up.

leeHS··on How to work from home without going insane (purple monkey dishwasher)
Purple Monkey Dishwasher!!!! I've said these words to the most die-hard Simpson fans and they look at me like I'm from outer-space! It's my favourite line, but this is the first time I've ever seen anyone quote it besides myself.

Sorry, I realize this doesn't really advance the discussion.

Poor journalism.
leeHS··on Ask PG: Limits on competitive startups?
Sorry, I`m not PG, but I couldn`t help but comment. I hope you don`t mind.

From everything I`ve seen about YC and PG, they seem to value the co-founder much more than the idea. So the second attempt may work, where the previous attempt failed, because the people were better.

My favourite story about YC are the guys from Reddit. When they applied, their idea was to develop an app which let you pre-order your coffee from Starbucks and avoid the line. The idea didn't go over too well, but PG and JL really liked the co-founders, so they brought them back and worked out a better idea. They realized that these guys were special enough that the idea didn't matter.

As for controls to prevent inside gaming...I'm curious to know the answer to this as well! Are companies encouraged to brainstorm together? If so, do they have to sign anything?

leeHS··on One of my favorite puzzles - what answer do you get? (image)
My first thought was 25%. Four options, only one is right. Then I saw that 25% appears twice, which reduces the available answers to three. But I have to randomly pick an answer, so there is a 50% chance I will pick 25%, a 25% chance I will pick 50%, and a 25% chance I will pick 60%. So isn't it depended on WHAT the right answer is?

He's saying that if you are a person who likes perfection, why do you not want to join projects to make bad code perfect, like debugging projects.

The other day I was at a charity who are really making a difference in my community, but who are lacking much needed IT support. I'm really considering offering my services for free. Not only will I be able to continue developing my skills, but I'll be helping a really great cause.
leeHS··on 15 year-old needs your advice
You seem like a smart kid. I would stick to what you're doing. Seek out other geeks and program with them. Contact companies that interest you and offer your services for free. Show them what you've already done. Keep working on your projects...remember, this is your portfolio. So when ever you get lazy, or lose interest in a project, just remember that at the very least you should finish for the sake of this portfolio.

I'm sorry, I don't have any links to interesting open-source projects.

Keep at it. Sounds like you're on your way to great things.

leeHS··on 15 year-old needs your advice
Forgive my ignorance, but is there an IT community in Belarus?

IMHO, I would go for the Computer Science degree. I didn't, and as a result had to really work to get a foundation in CS theory. I'm still working.

Good luck to you. At least you know what direction you want to go. At 15 I was still trying to decide between computer science, biology, and art! :)

leeHS··on Your DNA may carry a ‘memory’ of your living conditions in childhood
What I also find fascinating is the number of individuals with this sort of background reading/commenting on HN. I think it's great! Are many of you into Bioinformatics?
leeHS··on Your DNA may carry a ‘memory’ of your living conditions in childhood
Based on how meiosis works, I can see how methylation could be passed down to offspring. But these changes in methylation would have to occur within the specialized cells which produce sperm and egg. If the methylation pattern changes in your liver or heart cells, it doesn't matter since these somatic cells don't get to pass this information on to offspring.

Females are born with all their eggs, so any changes in methylation that occur to these eggs will persist into adulthood (I assume). But is it possible that these eggs are somehow protected from this alteration? As for sperm, these are produced within the testes following puberty, and are generated continuously. Therefore, in order to pass down altered methylation, the original gamete cells responsible for generating sperm would have to be altered. But if you wanted to do this successfully, you'd have to make sure to alter ALL the gamete cells. Otherwise you're gambling as to which sperm cell hits the pay load. Again, I'm curious if these cells are more or less prone to altered methylation.

I find this whole concept fascinating! Imagine...your dad gets bullied as a kid, results in altered methylation pattern, and this gets passed to you! Wow.

leeHS··on Admit it, Apple fans: Microsoft’s stores are a lot of fun
If it wasn't for the Microsoft logo at the back, I would have thought this was an Apple store.
leeHS··on Please review my startup. Safe text messaging for teachers
I'm also married to a teacher, and I mostly agree with aspir, especially wrt teacher to parent communication. However, I don't see this as controversial. Yes, teachers have to watch what they say, but this is true of verbal communication as well. I'll be curious to see if this is "cool" enough for students, and desirable enough for teachers who will most likely be using this during their off-hours as well.

Love the design btw. Simple and clear.

leeHS··on Show HN: my 4-y-o son drew a video game. He drew then we hacked together.
I'm playing this while my 6 week old son is asleep and strapped to my chest.

I can't wait to share with him the joy of programming.

But I sometimes worry that today's technology has come too far to be used as a stepping stone to teach kids. I remember as a kid messing around with a Commodore-64, then moving on to Q-Basic. These were not only the technologies of the time, but perfect for a child to pick up.

Maybe I'm underestimating the little guys. :)

I like this idea. I'm curious though...are you storing my user's info for me? If so, how do I access it?
