cqcn1991··on Show HN: Pocket Digest – an RRS reader without information overload
Hi, everyone, I'm a fan of Pocket, and I've been using Pocket's data to filter the my RSS feed for sometime. I end up with this idea, and I want to share it with you and the Pocket team.

The basic idea is that, by using Pocket data, we can subscribe as much as possible blogs as possible and end up with better content that we might interested. This was a critical problem for typical RSS readers and now I see it can be solved decently by Pocket.

The full thought is at https://medium.com/@cqcn1991/pocket-digest-your-personalized...

cqcn1991··on Show HN: I made a site to help you find good nonfiction books
Hi, anyone enjoys reading nonfictions (e.g. business, social science, biography and others) here? I enjoy reading them a lot, because I can always learn a lot from them.

However, a lot of books on Amazon simply do not have good ratings, and sometimes I need to spend a long time to find a good book to read. so I collect the data from Amazon and apply some filter and made this site. The books being displayed are with good review stats.

I hope this is helpful for you to find some good books.

cqcn1991··on Show HN: Tech Insigt – Awesome blogs on technology, startup and innovation
Hi, This is an awesome list of blogs on technology, startup, and innnovation. I put the blogs I enjoy most on this list. If you like Paul Graham, Andrew Chen, then you may also find some other blogs that interest you here.

Addtionally, this list is also the sources of my small website (http://productchaseapp.herokuapp.com/tech2pocket), where I collect the articles and then prioritize them using some simple data analysis.

cqcn1991··on Show HN: A simple wind speed and direction probability model (Jupyter Notebook)
Thanks for the suggestion, and that's why I'm still working on the paper and related documentation.

Additionally, my Jupyter Notebook is getting too long. I'm thinking how can I decouple it into several parts while still make it easy to use. That's the main reason I haven't add any text in the it. The notebook would get even longer, making it extremely hard to read.

Wow, didn't expect there would be a guy with similar research interest. That's interesting.

I'm not sure if this is the right place to post it. It's just a simple probability model of wind speed and direction, that I made using Jupyter Notebook. This is my master thesis (And I'm still working on the paper).

Hi, I'm developing a new sidebar extension for the Ipython Notebook. If you write long docs with .ipynb, you may try it as well.

It's not ready yet, but I want to see your feedback. And if anyone could join me would be great, I'm not very good at programming.

It's basically a filterd RSS reader. And I'm wondering if there is a better approach.

cqcn1991··on Show HN: Tech2Pocket – find better tech articles with Pocket
Hi all. I just made this demo a while ago. It helps you to find better tech articles with the Pocket Index (unofficial). By filtering out some not-so-popular-marked articles, it saved me a lot of time, and I hope it would help you as well.
cqcn1991··on Show HN: Tech2Pocket – find better tech articles with Pocket
Hi, this is a small demo I made not long ago. I love to read articles about product, internet, especially from Great people like Paul Graham, Andrew Chen. etc. So I thought about setting up a personal RSS reader, and filter the feeds with Pocket Index, to select out better content for reading. And here is the result. It's not pretty-looking, but it's useful for me, and I hope this would help you too.
cqcn1991··on Show HN: Product Chase, top weekly and monthly products from Product Hunt
That's so sweet! Honestly I put it there a long time ago, when I didn't know that most products there are 'toy-quality', so I thought most of them would be covered in Tech News, which now turn out to be wrong. I definitely change it to google news search. Thanks a lot!

Well, could you be more specific? Any example?
cqcn1991··on Show HN: Product Chase, top weekly and monthly products from Product Hunt
If you find checking Product Hunt everday is a bit of time-consuming, then you can try Product Chase, in which I re-arrange their products in a weekly/monthly manner. May be helpful for someone.
