There's no such thing as an original idea. Every idea worth having has been had thousands of times already.

This is a open repository of personal ideas. Some of these are based on personal interactions, bug reports, and discussions I've had with lots of people. I've tried to give credit wherever possible. I also try to reference similar/existing projects that might relate to the idea, so if you know of something that is interesting in that space, file a PR or send me a link.
This is a privacy-awareness application that relies on the TrueCaller data-sharing model. It is meant to teach users that their privacy is not in their hands, but in the hands of those that they trust.
The idea itself is to let people browse facebook as someone else. This is done by note of the following points:
- Facebook allows OAuth API access that allow your application to perform tasks as any user whose token you have.
- To start using the service, you must "hand in your data" first. Just like TrueCaller uploads your entire phonebook before you can use the app, openbook requires you to give us access to your facebook account before you can use openbook.
This has massive privacy implications. People assume their facebook data (such as information on your about page) to be available to only people they have friended on facebook. However, it is also accessible to all applications you authorize, which is what we are exploiting basically. I expect the application to be banned and have its keys revoked within a day or two. If I were to make this, I'd rather not use my own facebook account for fear of getting it suspended.
Since the idea is to teach users about privacy, openbook will not ask for access to all data. It will probably use a harmless data-property that will essentially be made public to all users of the app. Currently, I'm thinking "No. of Friends", which is not always available to public if you've hidden your friend list. It is harmless enough to not cause any mayhem, and yet vital enough to just show that such attacks are possible.
- Homepage will be a simple FAQ on privacy-related matters and what the app does.
- A login page
- A search interface to search amongst all users using the app.
- A profile page of any user, where you can see their data using someone else's token.
Unlike facebook, which can directly access any data on their servers, we are limited to using their API. Which means getting data for any user has now become a mapping problem. You need to know which tokens can access data of which user. This could be made possible by pre-mapping the users accessible via each token, and refreshing each token's list every week or so (as you make new friends).
This idea probably breaks lots of point in Facebook's ToS, but that doesn't mean it can't be built.
This is essentially a unified profile mechanism, where a user's identity is defined by all of their activity on various networks. While this has some cool sub-ideas (like correlating activity between various networks), the most important implication that arises is that it can be a perfect tool for stalking. However, you can easily add in consent from the original profile owner to clear that concern.
iStalk lets you "follow" a person across various networks that they belong to. Some networks, like twitter are mostly public, and can be followed very easily. But other networks (like Facebook) are harder to follow by virtue of them requiring a "connection" between the two users. iStalk makes it easier for you by using your account on that network as a proxy-connect mechanism.
Basically, you give us your access tokens, and we use them to stalk someone for you.
A profile creation page allows you to specify as much information as you have on the person. This includes their facebook, twitter, last.fm, github usernames for eg. Each integration you want has to first be verified by you granting us (iStalk) access to your account (via OAuth).
Once a profile has been created, we will continuously long-poll the service to fetch new information as and when it becomes available. Real-time notifications are delivered to you as the person's activity is tracked.
There are a dozen bookmarking services out there, many of them quite well done. However, most services are focused on the idea that bookmarking is a lone-person habit, which someone does in isolation.
I've often described the idea as "dropbox for bookmarks". The core concept is to allow a bookmarking "tag/folder" to be shared with another user, two-way. This means any of the shared members can add/remove bookmarks from that folder. All updates (addition/deletion/edits) are notified to every member in the group.
Bookmarking for Teams, in essence. Some good alternatives are listed in this quora answer, which you should read and follow if you're interested in this.
I've described this idea somewhat better in a chat log at collaborative-bookmark.md Google Spaces did some nice work here, but the product was shut down within an year of launch.
Lightspeed for Chrome
Lightspeed is an experimental UI design (not implemented) for Firefox that focuses on making the New Tab page more functional by giving the browser a decent way to search across bookmarks, open tabs, and history.
It is a pretty neat idea (see the video linked above). My first thought on seeing the video was that most of that stuff could be done using the Chrome APIs for Chrome as well. Chrome does offer a way for an extension to override the new tab page, after all.
The discussion on HN is also very good.
Update: There is some progress on the WebExtension porting of Lightspeed, given the recent Firefox updates. With this in place, it should be relatively easier to port the webextension version to Chrome itself.
I like the analytics that WolframAlpha provides for Facebook. Except that they are not really that useful. I'd like an easy query interface that let me "filter" data points, and get back open-data via the Graph API. This means, for eg, getting the most liked music artist among a subset of my friends. The interface I'm thinking of right now is like Gapminder, which allows you to "play" the dataset as it evolves over time.
A recommendation engine built on top of my facebook data is a good idea, I think.
API for Workflowy
Workflowy is a cool tool that I use for note-taking. It allows infinitely nested lists with @mention and #hashtag support. One thing it lacks currently is API for me to access my own data. I think workflowy is a great tool that could become a lot better if there were a way for developers to hook into it. (For example using workflowy as a data-backend for a todo-app).
My notes for lettersafe are on workflowy.
The idea was to build a zero-knowledge email storage. Kinda like lavabit, with a few minor changes. After thinking about it for months, and working on it for a few days, I gave up on the idea. I understand now that server-side email encryption can never be a good idea.
Email on top of keybase
Keybase has a cool API. I wonder if its possible to build an actual email service on top of keybase?
The original idea was from before Keybase had a chat feature, and I wanted to build an email service that used keybase to send and receive messages. Would have turned out similar to Keybase Chat.
How I'd approach it today is to use Keybase Social Graph for encrypting emails and make it easier via plugins/extensions. The ideal flow would be:
Use the Keybase Social Graph for encrypting emails and make it easier via plugins/extensions. The ideal flow would be:
- Login to GMail
- Compose an email to firstname.lastname@example.org
- Extension pops up: "Hey, looks like this user is on Keybase already as keybase.io/captn3m0. Would you like to encrypt this email?
- If user clicks yes, do a keybase auth and follow the user as well, perhaps? (not sure if possible)
- Also give user an option to "Encrypt all emails sent to users with more than X followers)" or something similar...
Doing the same thing on the receiving side is trickier though, but I like the idea of using Keybase to discover anyone's public keys instead of the standard Web of Trust.
A Keybase plugin for Thunderbird would be similar in scope.
Newsletters for GitHub
A lot of github project owners would like to send out newsletters to all of their stargazers. However, GitHub doesn't provide anything for that. An easy way would be to integrate StarGazers with MailChimp, making sure that people can unstar a project to unsubscribe from the mailing list.
Only the repo owners and collaborators (maybe) should have access to sending out newsletters. For bonus points, you can replace mailchimp with your own solution.
This could even be monetized slightly for paying off your server costs: newsletter access for projects with >1k stars (the mailers that would cost you money) cost money to the repo owner as well.
So a tiny python package pays nothing to update its users about a new release, but if Angular team wants to send out an update, that gets paid.
And finally, this should automatically subscribe you to any new GitHub releases in any project you have starred. This is a missing feature that I think can be best implemented by a third-party for now.
Hacking via OAauth tokens
While pen-testing, once you've gained access to the target, it is often necessary to install a backdoor to mantain the access. While this is easily done in case of root access to the machine, this is not that easy if the target is an email account, lets say.
Many online services today (with data of considerable value) offer developers programmatic access to their data by use of APIs, which are usually authenticated via OAuth tokens. What I intend to build is a suite of applications (or a single large one) that allow you to use the application as another user, just by setting up an access token.
While this is certainly possible with existing tools (such as the Facebook Graph API Explorer), it is cumbersome and not user-friendly. The application will mimic the interface, usability, and looks of the actual application to let you maintain access easily enough.
But OAuth tokens can be revoked
That is a good point, but one that fails in practice. A password change in most services does not trigger an automatic token revocation because that would leave a lot of developers and users unhappy. However, neither does any service warn you to check your approved applications (especially after a hacking attempt).
- You gain access to someone's account.
- You create an application (using a fake account or the victim's own account, so its not tied back to you)
- You setup our app (direct deploy to Heroku)
- You configure the app with the application credentials (app id, secret key)
- You authenticate the victim's account against the app
- You use the application to access the user's account
The account access will continue till the victim checks his/her approved applications.
Pluggable Notify Daemon for Linux
Not another window manager daemon, because lots of them already exist and there are already good APIs in almost all languages that make it easy to integrate with all of them. However, Linux DEs are still missing an easy way for me to get notifications about the thousands of little different things (such as build notifications).
The idea is to have a simple config where you can connect your bazillian accounts via OAuth, and we will poll all your accounts and give you "clickable" notifications for each of them. (GMail notifications might open your mail client if you click reply)
Keep it pluggable, otherwise its of no use.
Telegram To RSS
There are quite a lot of Telegram channels that are popping up these days that I really like using. Except there are lots of issues with telegram channels:
- They are inside a closed network by-default. In order to access them you need to use the Telegram client
- They are not linkable
- No sharability without their client, and even then the content is duplicated.
The idea is to create a generic website that does these 2 things:
- Publish an RSS Feed of every telegram channel it knows about.
- Provide a direct link for every feed item on the RSS, so users without RSS readers can also browse through the listings.
web.telegram.org is taken already by the web client, maybe something like
opentelegram.in should work fine.
Disable Local Fonts Extension
A simple browser extension for web developers that disable local fonts from loading. Alternatively, it raises a grave warning if a web-font was bypassed for a local font. This is helpful if you are a developer:
- And have some specific font installed locally (say Font Awesome)
- And are developing a website that uses that font locally
- And forget to include the Font in your stylesheet
The page continues to function normally in your development setup, but breaks in production.
Based upon this chrome bug request, which asks for this feature.
I came to know about this because of a comment on my "disable-web-fonts" extension, which does the opposite. This might be handy for people who want to make sure that web-fonts are working fine for all users.
Arch Linux Package Build System
The Arch Linux User Repository is great. Except, a lot of packages rely on building-from-source since no binary releases are available. However, the build steps for these packages work very well, resulting in a working build. The idea is to create a AUR build server that takes in a AUR package name as input (it can have a whitelist of such packages), runs it in a docker container, and outputs a generated package file (
tar.xz) that can then be directly installed on any machine.
This has some security concerns, mainly how do you trust a binary package an external server built?
Planning to solve this with attempting reproducible builds, and publishing everything. You can audit any build artifact whenever you wish. I'll likely just use the Docker ArchLinux image and build against that.
Moreover, the primary audience for this would be me. I would really like to get packages that can be installed much faster because I don't have to build them. I can just have a script that instead downloads the latest build from the server instead of AUR and then just installs the package instead of building it locally.
Take a look at https://github.com/Foxboron/arch-auto-build, which is a very similar attempt at this idea.
This is already handled by the Arch Build System (albeit without Docker). Using that might be a better idea.
Hacker News Research Bot
A bot that posts paper abstracts and links to PDF whenever a paper referencing a research paper is posted to Hacker News. Most scicomm posts that make it to HN almost always have a primary paper reference, and someone ends up posting the paper abstract along with a link to Arxiv or SciHub usually. A bot that automates this for all HN submissions would be a fun project.
Update: Someone did this! See @randomdrake's comments on HN.
Update 2: The mods are not very happy with the abstract being posted, but the rest should be good.
For Bonus Points: Include a link to the fermat library URL of the paper (if available).
All of our company has contact numbers added on Slack, but it is cumbersome to find someone's profile on Slack. A simple dialer application that does OAuth-verification on your Slack profile to get a list of the entire organization, and present a simple dialer for all the people who have contact details added.
Interface would be a simple grid of faces, click to dial, sorted by frequency. A simple search-as-you-type box at the top. Can also be done as a PWA to easily make it cross-platform.
Note that this requires a Slack team with a paid account. I'll help you get a trial so you can build this.
Database Conversion Toolkit using an ORM
Something that lets you switch your database between SQLite/MySQL/Postgres/... by using an existing ORM framework to import and export out the correct commands.
The grammar differences in most databases are taken care of by an ORM, and the remainder is just switching your ORM to use an existing database as the source of truth. Even a specific variant (say SQLite to MySQL) would be great to have.
Thought of this after spending a lot of time trying to migrate my Grafana/Gitea setups from sqlite to mysql and trying every solution in this SO question.
Tachiyomi is a Android application written in Kotlin that scrapes comics from various web sources. A headless version of it would be great to have, replacing projects such as https://github.com/evilhero/mylar with something much more stable.
The end goal is something that works as a "minor" (<200L) patch on top of Tachiyomi, and does a JVM-desktop build which can be run anywhere. A sample README would look something like:
A headless build for [tachiyomi] which you can run on your server on a schedule to download comics. This downloads the comics in plain images and then converts them to CBZ format with metadata intact. A new release is generated for every Tachiyomi release.
Get the latest release from the [releases page].
Run it as the following:
java -jar tachiyomi-headless -c config.yml
config.yml file looks like:
dir: /home/comics/ format: cbz # All the tachiyomi extensions come pre-loaded # https://github.com/inorichi/tachiyomi-extensions comics: - http://readcomiconline.to/Comic/Marvel-The-End - https://manga-fox.com/one-piece
Simple web tool to generate OPML files to let you use RSS feeds everywhere.
For eg: Every repository on GitHub has a releases RSS feed that you can follow. However, you need to follow each one individually. Thankfully, there is a nice spec called OPML which is used to pass around lists of RSS feeds.
What if one could generate a OPML feed for:
- Releases of repos that you have starred on GitHub
- Authors that you follow on GoodReads
- Bands that you follow on BandCamp
Bangalore Events List
- Want to keep the name generic to support non-tech events as well
- ICS support (WeBuild.sg/cal for demo) is a must-have
- (They have a RSS feed as well!)
Domain name suggestions are welcome. Since blr doesn't have a TLD, I was considering using
Initial Work: https://github.com/captn3m0/gardencity.events
Amazon Price Tracker with RSS
There are some nice open source trackers available for Price Tracking Amazon products, but I would like to see something that generated an RSS Feed.
This could be built on top of RSS Bridge fairly easily. Configuration options would include:
- Min Price (Only add to feed if price is below X)
- Amazon Country/Domain (Use the specific Amazon website)
- Item Id
Instead of forcing users to do manual imports of OPML feeds, let them auto-subscribe from feeds using a dynamically generated OPML feed. This is not a product idea by itself, more of a extension idea for existing RSS Readers.
See related discussion on the tt-rss forums.
A lot of Indian Government websites are inaccessible on the public internet, because they geo-fence it to within Indian Boundaries. I made a list of all Indian Government Websites, and the idea is to make a Indian Proxy service that specifically works only for the Geo-fenced Indian GoI websites.
For eg, if
uidai.gov.in is inaccessible, hitting
uidai.gov.sanskariproxy.in will get you
the same result, proxied via our servers.
This is not intended to be used for actual usage, just research purposes. Will help make the UIDAI (and other GoI) websites accessible to a much larger community.
