A twist on a simple timer / productivity app. When you want to focus, instead of pressing start, you ask for time from someone else. Once you've completed using that time, you get to pass it on to somebody else. Completion depends on approval from the previous owner of the time. As the time gets used, it gets passed from person to person, creating a "time chain." Participants get to see the history of the time chain.…

A file naming convention (lightweight markup) that would allow us to store structured (meta)data right inside file names. Obviously inspired by Markdown and CSV. We could then build lean, database-less asset management applications, while the user data (i.e. the files and their metadata) would always be portable, across platforms. Take for example: J.M.W. Turner | Rain, Steam and Speed | ···· 1844.jpg W. Blake ···· |…

You'd be interested in the Be File System (from BeOS / Haiku) for inspiration:

http://arstechnica.com/information-technology/2010/06/the-be...

It has support for database-like extended file attributes, which can be custom attributes!

For example, a `person` file would have all of the normal fields you'd expect from an address book as file attributes: http://www.birdhouse.org/beos/byte/24-scripting_the_bfs/ https://www.haiku-os.org/docs/userguide/en/attributes.html

Technical: http://www.letterp.com/~dbg/practical-file-system-design.pdf

Though you seem to be against specific file systems due to non-portability and that is understandable.

Build a company around creating a best in class development environment that they can sell to other tech companies. This would involve everything from repository management (on top of git) to build & compilation tooling to automated testing and probably more than that eventually. Once companies reach a certain scale they inevitably expend some of their resources on building internal development tools. At Foursquare w…

Hmm, would Atlassian count?

Atlassian's product line suffers from the disjoint problem, which makes sense since they bought most of their products from other companies. To tackle this problem, you really have to have a unified base that all your tools are built on and it has to be flexible enough to work with any possible process and workflow.

My GitSense product is very similar to their fisheye product and due to how my system was built, I can actually integrate better with their own product line than fisheye can.

== Dying Skills, Lost Tech ==

I knew a chap who could roof a home with Cotswold stone. He knew how the stone was quarried (but he didn't do that bit) and how it was made into roof tiles (but he didn't do that bit very often) and he knew how to roof a house using those tiles. There are not that many people who can do that anymore.

There's a meme about the NASA Saturn V rockets that says we've lost the paperwork and thus re-making them would be cery hard, and could involve rediscovering technology.

The Domesday project is sometimes used as an example of digital obselesance http://en.m.wikipedia.org/wiki/BBC_Domesday_Project

And here's an example of someone looking for Cray software and code and documentation https://news.ycombinator.com/item?id=3464546

So, this would be a site that interviews people (using crowdsourced interviews) to glean information about how they do or did things, and why, with video if possible of them demonstrating the techniques and equipment and methods.

This would be a teeny bit like the Endangered Language Project. http://www.endangeredlanguages.com/about/

There would need to be some way to control for truth and accuracy[1] and also some suggestions for what is a good interview.

[1] my dad used to tell quite a few lies. One of these (well, one set) was about his diabetes diagnosis and treatment. He claimed he had been diagnosed as a child while still at school, and that he had to sharpen his syringe on the stone floor. Utter cobblers, but somehow it found its way to an academic site. I sent them a polite email and they made their disclaimers about uncorroborated etc a bit clearer.

Travel Assistant While travelling I like to keep family and friends involved up to date about my travel plans - itinerary changes, delayed flights, boarded flight, landed flight, etc. Instead of a pushing updates by texting 3-4 different people, I want to be able to provide an update in one place, say, on the Travel Assistant app, and my family can receive appropriate updates.

1) daily email that highlights the top 10 posts on HN (by points or by most comments)

2) simple way to share sensitive financial details with others (e.g., credit card payments, pay stubs, paypal history, bank transactions)

A major pain point in my life is house maintenance and repair. I really miss having a (good) landlord. That's what I want - a single point of contact to manage the upkeep of and fix any issues related to my home. There's so much friction in the process of finding the various contractors needed to keep a home in good order. First you have to search on craigslist, angieslist, or google for contractors that service your…

I know a loss adjuster who has many years experience with insurance claims who would have exactly the expertise needed to find the right people in all the areas you describe. Largely his skills are used to benefit the insurance company (that he works for) but they could just as easily apply in the customer's favor. I'd recommend targeting prospective employees with that kind of experience.

1. Combining the mio water flavoring , which gets very good reviews in his category ,into a cap of a reusable water bottle ,similar to pillid[2] 2. Pcb layout design, in the electronics industry, is somewhat similar to games like pipes. So why not gamify pcb layout[3] ? 3. Recently i read some interesting research about some electronic circuit. It would have been very useful to get access to a full diagram/layout and…

UK drinks manufacturer Robinson's have just released Squash'd[1], similar to your first idea [1] http://www.robinsonssquashd.co.uk/

Mio does look similar. the whole point is make it easier to carry it inside the bottle - less hassle, less forgetting, less things to carry.

Even better would be integration inside the reusable bottle cap such as you just press somewhere to flavor a bottle.

This might be fairly simple, but I can't find a good solution - A replacement for Google Groups. More specifically, a better UI to use Mailing Lists. Perhaps like vBulletin or other advance forum software. Maybe even built-in support in my email client? For the life of me, I can't find a good way to use Mailing Lists. I don't like receiving 40+ messages every day, but I don't find digest mode good enough either. Goog…

In my opinion, discussions were handled better in the old Usenet days. How about running a private NNTP server and use one of the programs that forwards the mailing list to the NNTP server? There are still lots of good NNTP clients out there like XNews

I can't agree more and what I absolutely loved about Usenet discussions was, every reply contains a subject line. And it was expected etiquette to change your subject line if your reply deviates from the parent.

With usenet, I could easily tell what I haven't read and if a branch deviates from what I'm interested in discussing, I can just ignore that entire branch.

GitHub for mathematicians. For every theory, define its axioms and valid logical steps. Let anyone build theorems based on these (validate them automatically), and allow people to fork others theorems to create their own. It's probably possible to get a lot of proofs from projects like Mizar and Metamath to start with, then let the community build on top of it. Maybe even a crowd sourced bounty program for unproven t…

> validate them automatically That's the hard part. There is some research being done in that are really interesting, such as * Koepke, Schröder, Cramer with Naproche http://www.naproche.net/index.php * Paskevich with SAD (unfortunately he stopped his research) https://web.archive.org/web/20131207185950/http://nevidal.or...

Maybe I'm missing something, but I don't see the problem. If your users submit their proofs one line at a time, then validating each line is O(1) if they give you the assumptions they used and the steps they took.

Edit: In case I wasn't clear, I didn't mean anything like natural language processing (though that would be awesome). I meant very strict formal math where everything is explicit.
