yawl··on The Elegance of the ASCII Table
I also wrote a chat novel about ASCII: https://www.lostlanguageofthemachines.com/chapter2/chat
yawl··on Show HN: I learned Pixel Art to build a game for my wedding's "Save the Date"
Love the design!
yawl··on Show HN: A storybook designed to teach kids about how computers work
Thank you all for the feedbacks, and extra thanks for those who read all three chapters. The consensus is the content is too hard for younger readers and I agree. I do have some ideas to improve, and will work on them in the coming weeks.

And I will probably ask for feedback again soon.

yawl··on Show HN: A storybook designed to teach kids about how computers work
Thanks. I will check it out.
yawl··on Show HN: A storybook designed to teach kids about how computers work
Thanks, that is good advice. You totally get it that I am trying to paint a future scene, but somehow did not deliver. This is the first time I wrote any long story in my life. I tried on my own kids but that is too small sample size.
yawl··on Show HN: A storybook designed to teach kids about how computers work
At very beginning I want to do it in comic style, kinda like “beast academy” style. But my art skill sucks, and ai image generator is not as good as I hoped. So I settled with chapter book, at least something I can produce. May be I should go game style "book" to be able to reach younger readers.

how about 5th grader or above?
yawl··on Show HN: A storybook designed to teach kids about how computers work
Thanks for the feedback. I have never done anything like this before so there are tons of mistakes. The flipping thing will generate a time sequence, I find it hard to explain myself.
yawl··on Show HN: A storybook designed to teach kids about how computers work
Thanks. Will check that book out.
yawl··on Show HN: A storybook designed to teach kids about how computers work
That is a good concern. I have to find another way.
yawl··on Show HN: A storybook designed to teach kids about how computers work
Thanks for the feedback. I changed the sentence to something else.
yawl··on Show HN: A storybook designed to teach kids about how computers work
Fixed. Thank you!
yawl··on Video matters But which hosting service to use?
Thanks for the info. We have tried Youku and Tudou on https://railscats-china.com but the embedding quality is bad. Will see whether there are plus account on those services.
yawl··on A Practical Guide to Use Spine.JS in Real World App
Thanks for the article. It's very helpful.

Have you ever checked artTemplate other than eco? https://github.com/aui/artTemplate

It's very fast: http://aui.github.com/artTemplate/test/test-speed.html

yawl··on Ask HN: How Much Can I Scrape?
Do not crawl too fast with yahoo, otherwise you will get 999 error -- which mean you will be banned temporarily.

Search 'yahoo 999' for details.

yawl··on HBase | An open-source, distributed, column-oriented store modeled after Big Table
Powerset (a search engine aquired by MS) is behind hbase development.

I have been using hbase in my project -- an interesting experience.

yawl··on Twitter Acquires Summize
Apparently summize found a quick exit after switching from book/movie/product review search to twitter search.
yawl··on Ask HN: managing subdomains cookbook
If they register the domain from you and you operate the DNS server, then you have the information to make changes for the user. I think that is what google does.

If the users own their own domain via a third party, you can not modify their DNS record unless they gives you their account. Or user can transfer domain to you.

yawl··on Ask YC: Bug tracking software?
If you are a rails shop, redmine is good too. I have used jira, mantis, trac, but do not like any of them.
yawl··on Ask YC: How do you upload to your web server?
I use Capistrano too. It is written in ruby but can be used by any non-ruby project.
yawl··on Summize: Search Twitter in realtime
I visited summize.com before. They used to focus on searching book/movie reviews. Now it is totally different.
yawl··on Are all the good domains taken?
Take a look of this one, a little bit of old but still helpful: http://www.yafla.com/dennisforbes/Interesting-Facts-About-Do...

I registered a 5 letter domain (xruby.com) in 2006. I think there are still 5 letter domains available, but good names are extremely hard to find.

yawl··on GPL'd Source Code
Right. There is no way you can relicense it. The derived code is still GPL.
yawl··on Ask YC: Google Code or Sourceforge
Agree, sf.net has too many projects on it and checkin/chekout speed is very slow sometimes. I have a project on Google Code and so far I am happy with it.

I also use github, so far has not seen problems. As ruby on rails moved to git, I believe lots of open source ruby projects may follow.

yawl··on Ask YC: How would you do keyword classification
I think every language has an open source naive Bayes/Bayes network implementation. And most of the time they are good enough.

KVM (support vector machines) so far is considered the best classification algorithm.

yawl··on Getting visas to attend programs like YC
Yes, as long as you filed the H1B transfer application, you can work for the new company. You do not have to wait for the approval or even the receipt (it could be nice to have the receipt as it helps to prove you filed application).
yawl··on Getting visas to attend programs like YC
Switching jobs will require a new H1B, normally called 'H1B transfer'.
yawl··on Getting visas to attend programs like YC
There is no grace period for H1B, not a single day. If you leave your H1B job, your H1B status is lots immediately.

It might be possible to apply a new H1B based on your YC company, or obtain other work authorization like EAD to be able to work in the US.

yawl··on Ruby's not ready
I like ruby as a language, but not the implementation. And as a matter of fact, matz knows and acknowledged he is not a good implementator.
yawl··on Ask YC: Can a person in US on F-1 Student Visa be a co-founder?
Assuming you are on F1 visa without OPT, you can be a co-founder, but you can not 'work' for this company you found. The key is not about making money or not, you can receive passive income like dividend. You are not allowed to 'work', even volunteering will violate your status.
