Problem: Making appointments with others is easy, making (and keeping) appointments with YOURSELF is hard. Easy to get distracted, hard to get back on track and make consistent progress.

Project: http://Focuster.com - automatically schedules your todo list in your Google calendar, uses smart reminders to help you manage your focus and recover from distractions.

* A pixel-perfect WebGL/JavaScript implementation of UIKit/QuartzCore that runs basic iOS apps in a web-based simulator at 60fps

* A Swift 3 -> JavaScript compiler with many language features, full type inference and more

* Many interesting ways of combining the above to form interesting new development/learning/prototyping tools

* One such tool/product has a full WYSIWYG app builder, with drag/drop UI components, auto layout, etc (think Interface Builder but with pluggable logic). I have a backend supporting this that can generate an .xcodeproj, compile, codesign, etc on the fly to a real, fully native app

Started as a browser-based version of Reveal (https://revealapp.com/), and spiralled out of control from there.

One of the spin offs: http://shopmo.co (not fully live)

I'm building a wholesale order sheet that is shareable with a link.

https://www.deliteapp.com

Businesses are purchasing millions of dollars of product through paper order sheets or PDFs passed through email. Delite takes out the hassle for the buyer - they can fill out quantities and submit the order right on the form rather than download, scan, fax, send back, etc.

The vendor can share these orders through text, email, or on an in-person basis. The forms can be created and customized with a form builder, and also come with a backend to manage orders and customers.

Prime Factorization - Just as a fun side project. I do not expect that I will ever be able to solve it but at least once a week I learn something new about math! I've Been working on it for 3 years now and It's getting more and more fun every day. In fact, I have rediscovered so many things on my own that I thought never existed. My biggest "Eureka" moment was when I discovered factorization via the difference of squ…

I have had a hard time with math in formal education, I would love to hear more about how you are learning it now :)

I'm an undergraduate at UMD working remotely. As a side project, I am working with a friend on https://txtpen.com txtpen provides highlights and context comments for websites. It is like medium for non-medium sites. Most importantly it follows the W3C Annotation Standard. It is so close to finish. If you have a tech blog and would like to be test it please email me at ricky@txtpen.com Any feedback is welcome. Thanks…

How's your side project differ from https://hypothes.is, and how come it's not possible to highlight parts of another highlighted piece of text?

Good job for following the W3C Annotation standard!

I've been working on a new programming language mainly to be what I think Go could have been. I think that it is important for us to have a compiled language that feels like a dynamic language. Its taking a lot of influence from ruby, erlang, and some assorted functional languages.

Any example syntax? Sounds like you're implementing OCaml with Ruby syntax.

I don't really have much out there right now. I have some spec, but it's really out of date. I have done some ML and I would say that while patten matching/powerful type inference are important to the language, in a lot of other ways my language won't feel as limiting as a purely functional language like ML. One of the important things I think a modern programming language needs are functional components that can be used when necessary. An example is annotating when you want the compiler to verify that a given function is a pure function(no side effects). This allows the compiler to make certain optimizations in both removing computation when results are ignored, and massively helps with concurrency(functions can be run in parallel when you have the guarantee that they won't interfere).

Project: In early prototyping a IMSI-Catcher Detector. Why another IMSI-Catcher Detector? Mainly trying to address the problems with the current open source solutions which is that they are tied to phones, the phones must be rooted. Given that there is no such thing as a secure phone something that runs on other devices using software defined radio would be better, it is also unreasonable to expect everyone that woul…

Sounds interesting. Do you have a website or blog where I can look for updates?

It isn't presentable yet but the project is open on GitLab if you want to watch it. No website yet but it is planned once the prototype is completely functional. We plan on having having it functional within two months then to clean it up before deciding if we are going to move forward with it.

* Project GitLab: https://gitlab.com/finding-ray

* Documentation: http://finding-ray.gitlab.io/antikythera/index.html

It includes some support projects like dockerizing of GNU Radio for use with the application, which is a beast to install.

My current side project: I am working on an app to go through my social media accounts, pull down the text of every URL I have ever posted (2,000+), and do natural language processing on the content of each URL retrieved.

Reasons I am doing this:

- I wanted to brush up on my Python and get acquainted with the request and BeautifulSoup modules

- I wanted to use Sqlite for a project and try out some new database design ideas in a non-production environment (immutable rows and JSONifying all data that's not indexed, for example)

- I wanted to get familiar with natural language processing in Python (NTLK module).

Been working on it on and off over the last month or so, and am trying to make some sort of measurable progress each evening. When completed, I'll put the code up on GitHub along with any interesting results I obtained.

Earlier quoted context omitted.

I'd find that really compelling. Consider hand-producing a sample via manual audio editing, to demonstrate the limits of what ought to be possible. Find some audio you think could be listened to at that rate, see how fast you can listen to it via standard sound stretching techniques (e.g. libsoundtouch and similar), and then demonstrate how much better you can do with hand-editing. Worry about how to automate that af…

Yea, it's a good point. We can logically distinguish between the basic audio problem (which might be really hard) from the automation problem. On the other hand, suppose we somehow got good training data by getting a bunch of audio samples at the same number of words per minute that were graded by human listeners as easy or hard to understand. Then in principle something like a neural net might figure out what audio…

Sure, you could try any number of things to produce a solution. But even if you try an approach where you don't know at first what might work, you should likely still put effort into figuring out what features made it work, so that you can improve it further and maintain stability.
