ldenoue··on Ask HN: What makes an online course amazing?
Why does it feel important to you that the speaker be standing?
ldenoue··on Don't Touch Ya Face
I also made one using BodyPix.js see https://www.appblit.com/handoverface
ldenoue··on What's so hard about PDF text extraction?
Detecting where tables are is still an active research areas. Once we know where on the page, it’s easier to parse out their structure.
ldenoue··on What's so hard about PDF text extraction?
Or maybe use a text corpus to infer likely next words between 2 lines of characters so we can infer the reading order and columns using the text.
ldenoue··on What's so hard about PDF text extraction?
That’s the approach I’m using to reformat “reflow” PDFs for mobile in my app https://readerview.app/
ldenoue··on Ask HN: Is reading PDFs on mobile a pain?
PDFs of research papers are what I often read on mobile, and I find it hard. Check out the app I published if you have an iOS device: it’ll reformat your pdf so the content reflows to fit your screen. https://www.appblit.com/pdfreflow
ldenoue··on Ask HN: Is reading PDFs on mobile a pain?
Yes but converting a pdf to ePub is not easy (to make the ePub reflow the text at least). What I’m working on could output as ePub.

And on desktop you’re fine dealing with PDFs in the browser? Just posted a video demo of what a pdf could look like once reflowed as HTML (look at the HTML version after second 10) https://www.youtube.com/watch?v=mSRFcLovatI
ldenoue··on Ask HN: Is reading PDFs on mobile a pain?
thank you. I never considered it would be useful on desktops too. I guess we now have expectations about how web pages behave in a browser, and what we can do with them; but when the browser loads a PDF, all that is gone, or not working the same way.
ldenoue··on Ask HN: Is reading PDFs on mobile a pain?
What kind of analysis and extraction? Figures, tables? Other?
ldenoue··on Ask HN: Could somebody reccomend me a hosting service for personal use?
Google App Engine has been great for me and it’s free. I’ve hosted several personal sites on it since its early release for python, but you can now use many languages. I host now https://www.appblit.com
ldenoue··on Show HN: Remote Contract Only Job Board
It’s a good concept but limited posts for now. I wonder why we don’t write a twitter search engine that automatically finds these kinds of job postings and aggregates them by location and company.
ldenoue··on Ask HN: What best crowdfunding site for my PDF 2 HTML converter?
What is or was your platform? Wouldn’t giving free access to the app be a reward?
ldenoue··on Ask HN: What best crowdfunding site for my PDF 2 HTML converter?
No, pdf.js displays PDF documents in the browser, but not as responsive HTML (it actually renders pages into a CANVAS element and then adds text selection by overlaying DIV elements over this canvas)

My app converts the PDF to a truly responsive HTML document, so you can view this document as any screen size (ie there’s no fixed layouts used)

ldenoue··on Ask HN: What best crowdfunding site for my PDF 2 HTML converter?
I have another app based on the same tech but that keeps all formatting. It’s called Pdf Reflow on the App Store. But I gather from the community that a pure HTML converter would be greatly appreciated, even if some characters are lost in translation...
ldenoue··on Launch HN: Remote company culture book for the Slack generation
How come the text is centered instead of left or justified?
ldenoue··on Show HN: High Quality Mobile Friendly PDFs
You can also try the web app at https://docushow.com
ldenoue··on Kurt Gödel's Letter to John von Neumann (1956) [pdf]
Mobile version here https://docushow.com/viewdocchris?url=http%3A//www.cs.cmu.ed...
ldenoue··on Ask HN: Do you read PDFs on small screens?
But if the pdf looked readable on your Android then you might like to read them right there as opposed to later on your laptop, right?
ldenoue··on Ask HN: Do you read PDFs on small screens?
That’s why I am doing it: for myself first but I’m still trying to understand who would really use this.
ldenoue··on Ask HN: Do you read PDFs on small screens?
Oops that’s a problem with finding columns. I’ll see how to solve it. Thank you!
ldenoue··on Ask HN: Do you read PDFs on small screens?
What link was causing the crash?
ldenoue··on Show HN: Chrome extension to highlight web and PDF
New is the ability to highlight pdf documents (in addition to web pages)
ldenoue··on Show HN: Fill Paper and PDF Forms Online
Do you think PDFjs could be extended to write new text inside the PDF, all client side? At the moment I’m only aware of PDFBox from Apache to do this, but that’s server side JAVA...
ldenoue··on Show HN: Arxiv Vanity – Read academic papers from Arxiv as responsive web pages
shameless plug: give https://docushow.com a try!
ldenoue··on Show HN: Arxiv Vanity – Read academic papers from Arxiv as responsive web pages
Thanks for linking to https://docushow.com Also a work in progress, but PDF reflow is a hard problem so you never ship if you want to solve all cases :)

Your solution using the LaTex source generates really nice HTML, congrats!

ldenoue··on Show HN: Open source Deep Learning Background removal service
When I tried the client side version on the same image, it wasn't good compared to the server side. Are you using a different model on the client?
ldenoue··on Show HN: Play rock-paper-scissors against your computer via webcam, neural nets
Looking forward to a YOLO or SqueezeDet or SSD+MobileNet version!
ldenoue··on Show HN: TensorFire
Would be great to port YOLO on your library; always an impressive visual demonstration
ldenoue··on Ask HN: How should I teach code to kids?
I taught my 8 years old girl using JavaScript and we made a simple game (numbers falling from the top of the screen and you have to click them to make a number: e.g. "3" and "4" because the number to make was "7").

It eventually became PopMath (which I reimplemented in ObjectiveC for the iPhone) but she understood the concept of loops, random number generation, collision with sides (so x coordinate had to be reversed) and event handling (function to get the user clicks).

I also did the same with my son when he was 9, with another game where the player would need to use arrow keys to navigate a maze.

Also in JavaScript because they can see the results right in the browser, can easily add graphics, and even sound effects.

I think simple games are a great teaching tool.
