My main current project has to do with my home media system.

Any sufficiently complex media system needs either more than one IR or RF remote, or it needs a universal remote.

The best universal remotes are activity based, and maintain information about the state of the overall system.

However, it's been my finding that many of them (looking at you, Logitech) focus on the software at the expense of high-quality hardware that's pleasant to use.

So, what's a person to do? Implement customizable command logic for a variety of command output formats (serial, IR, HDMI-CEC) state management (power on, power off, muted, projector screen open, lights on or off, etc.), and logic (power button does this if we're in state 1; otherwise do that and shift to state 3) in a webapp interface that runs on a Raspberry Pi and that can learn your favorite dumb remote's buttons via LIRC.

I'd love for anyone with an interest or a possible use case to reach out; right now, I'm just writing for myself.

Problem: We believe document versioning is broken for most people: writers, attorneys, academics, journalists, etc. We engineers have Github, but others don’t. So, we decided to solve this problem and create Tuiqo Project: Document versioning for humans We built a prototype: http://tuiqo.com (video demo: https://www.youtube.com/watch?v=vBj8ezqLCOs ). We are accepted to YC Startup school founders track.

Quick note - your homepage says 'try without registering', but clicking on the editor button prompts for a login.

Hey, thanks for replying! This definitely shouldn’t be happening, would you mind sharing which browser/OS you’re using? Do you maybe have cookies/javascript disabled? You can send a quick mail to dzeno at tuiqo.com if you want.

I have a project idea that might be useful for someone to learn about audio processing (and maybe neural networks?). I like to listen to audio and watch video of podcasts (and lectures and other human speech) at faster speeds. Sometime, especially if I'm trying to "skim" to see if the media is worth listening to carefully, I'd like to listen at 3x or faster. Very often, the limiting factor is the intelligibility of t…

'Podcast Addict' (for Android) can speed podcasts up like this, up to 5x. Usually, I can comfortably bump the speed up to 1.25x-1.4x without any trouble. 2x for me ends up being too fast, but useful if you're skimming and not trying to absorb every second of the audio.

Project: I am working on improving the 2 factor authentication (2FA) user experience for end users.

Problem: 2FA is an east way to drastically improve one's security posture with many sites (e.g. AWS, Github, Google, Stripe, etc), but it is still an incredibly annoying user experience that gets worse the more sites you use it with.

- When I pick up my phone to enter a 2FA code, I often get distracted by an email, text, or other notification. I'll put my phone down a minute later and think "what was I doing? Oh right, I need that 2FA code".

- It is also annoying to visually identify the correct site/account combo in my list of 2FA codes because I use many online services and may have multiple accounts at each one (e.g. AWS).

- Though some apps have a better UI presentation of 2FA codes, the classic Google Authenticator app shows all of the codes in a single list and I would often put in the incorrect code from a row above/below what I intended because it was difficult to visually keep track of the correct row as I transcribe the 2FA code into my desktop browser.

- It is annoying when the 2FA code changes while I am entering it in my desktop browser. Often, sites will accept the previous 2FA code as well, but if I only entered the first 3 digits and don't recall the last 3 digits, then I have to start over entering the new 6 digit 2FA code.

I am working on a new user experience which replaces these pitfalls and annoyances with the ability to simply click a button on your phone as your second factor of authentication. This workflow is compatible with any site that currently implements 2FA (e.g. AWS, Github, Stripe, etc, etc) and provides the same level of security as using another 2FA app such as Google Authenticator, Authy, etc.

It would be really encouraging/useful if you could leave a comment explaining why you might find this new 2FA UX useful or not! Thanks.

We're working on a bulk editing tool for data cleaning and of CSV files.

Currently, cleaning data and editing a few thousand rows one by one isn't much fun. Excel, while magical, isn't made to clean data. With our tool, you can format fields by example and find and replace in groups. And with validations on fields, you can get feedback immediately on errors as you edit.

As a hardware side project I've been designing and building an open source split-flap display - the kind of electro-mechanical displays you used to see in train stations and airports that loudly flip through letters and numbers as they update. https://scottbez1.github.io/splitflap/ Have a few working prototypes ( https://www.youtube.com/watch?v=bslkflVv-Hw ), but I'm currently redesigning the electronics/PCB to make…

That looks great. Stanford has an awesome one: http://peterwegner.com/detail.asp?id=212

Earlier quoted context omitted.

basically doing it fast for large integers. Here is the challenge I am working toward: https://en.wikipedia.org/wiki/RSA_Factoring_Challenge

If you have a breakthrough and start factoring RSA numbers and >=1000 bit composites (edit: on a system that costs less than 100 billion $), I would definitely start thinking about OpSec and finding a nice signal free place to crash. Good luck :)

lol.

Like I said, I don't expect to reach any tangible goal. However, I am not looking for an extended "search" algorithm. I am looking for a "solution" or at least a solution in say O(log(n)) to begin with. That's the goal I put up as a challenge. I will most likely not be able to do that but still fun to try :D

Edit: Forgot to say thanks!

Just curious, how are you planning on approaching this problem in a way that apps like Authy aren't doing?
