Still looking for the Partimage loopback mount utility I remember stumbling across years ago but failed to bookmark and can not magically Google back up...

j_s··on Ask HN: Help me generate an idea for my next project
Find a way to break the metadata chain connecting Tor users to onion servers on the Tor network. Most specifically the 'logged in here, connection happened on the server discovered there' edition.

Not sure ethereum is good here vs. privacy-first alternatives, but also not sure if all that is needed is Mechanical Turk, or a Stallman-esque browse-by-email. Maybe a protocol where people can get paid to run an email re-mixer as an onion service?

Build a system where users get paid to click random buttons, invoking services on onion sites. The hard part would be preventing side channel attacks... same request length, truly randomizing delay between task submission and completion (or some sort of subscription to send a block of random data regularly but sometimes it's user-controlled), no permanent logs vs. getting paid, etc.

Riffing on a few useless ideas here on a low-traffic day since the ideas are not going anywhere without execution.

j_s··on Ask HN: Help me generate an idea for my next project
Implement microtransactions. This is a good 2nd business (for mixers!), where you have existing customers who might be willing to pay a bit extra to be able to support their favorite creators. It gains extra potential if you act as an exchange, giving a currency that has a solid history of cheaper transactions.

You might gain additional leverage by being willing to collect for people who aren't connected, but that can get awkward (allow donating to charity). Also, taking care of getting funds to designated recipients who want nothing to do with ethereum basically​ means the legal setup reporting money transfers.

I think the window for this is closing as some mainstream currency is going to do this right, or some cheap-transaction currency will become mainstream/accessible enough.

I am posting ideas as separate comments. Hope the weekend crowd can give you something useful.

j_s··on Ask HN: Help me generate an idea for my next project
Build an ethereum contract (or verify and use an existing one) that refunds all money received unless a 'goal' is met, like a 'guaranteed money back if useless' GoFundMe.

Allow people to submit ideas that you're willing to vet completion for (this gets tricky/arbitration-y, encourage splitting this up into phases/steps rather than a giant lump sum) like an 'only pay if you get it' Kickstarter/Upwork.

With a twist: find a way to use all the pending deposits for proof of stake and return most of what is earned to those who have committed to potential projects. Consider making your own transaction fee equal to the ethereum transaction fee for all your transactions.

I may spam a couple more as separate comments...

j_s··on Don’t do the long take home assignments like coinbase
> It's an opportunity to have a meaningful and relevant conversation.

This sounds like the key and something many who complete take home assignments don't get.

[edit] Thanks for taking the time to add a bit more context.

j_s··on Don’t do the long take home assignments like coinbase
> those who are competent and eager enough

That's one way to put it!

It's obviously none of my business, but I can't help but be curious whether you are currently responsible for hiring decisions, and if so whether or not you use take home assignments, and finally if so whether or not it is paid for. Or perhaps as an employee the process worked out for you. In either case, more details documenting how take home assignments work best in practice would always be appreciated!

A take home assignment beats many alternatives, but places the entire burden on the potential employee (employers love it!).

j_s··on Don’t do the long take home assignments like coinbase
I think this could be tempered by a "check in everything you've got after __ hour(s)" time limit. Maybe allow requesting the problem details whenever ready and expecting a response within a given time frame?

This definitely ups the pressure, and things like hardware/internet failures would muddy the waters.

It sounds like even a commitment guaranteeing opportunity for discussion & feedback would be enough to satisfy several commenters here, but that is rare for liability reasons when employees are turned down.

j_s··on Ask HN: How do you document your knowhow, past projects and lessons?
I am interested in personal experiences/anecdata documenting what happens to these collections when the collector dies. So much effort invested!

I plan to make sure organizational time pays off in the short term, and need to work up a 'site map' for my various digital collections (in the off chance anyone cares after I'm gone). Sharing as much as possible starts to make sense in the long term, so classifying what "must be private" must be done as part of the process. (A tiny bit of this aspect is reflected in how useful my own StackOverflow contributions have been across jobs!)

In this light, tools encouraging sharing useful specific technical info semi-privately within a small group of very close professional friendships start to make a lot of sense.

j_s··on The cost of games
Money is important, but is there a place here to discuss the 'time' cost of games? Games are a useful tool for relaxation and other purposes (and a comparatively inexpensive hobby) but in my case it is easy to get carried away! For my most serious addiction I have chosen to time-box my gaming by only paying for two months each update (every other year-ish).

It takes conscious effort and self discipline to change direction toward creation instead of consumption. The tiny bit of gamification here on HN has me completely hooked, but I cling to the notion that my participation is creating some value (however slight). I look forward to the day when maintaining CRUD web apps is properly gamified, so I can earn money playing games!

PS. There is another opportunity cost of games vs. alternatives which require strenuous physical exertion that cumulatively improve health and conditioning (exercise, sports, etc.).

I am still willing to agree to disagree (your service, your ToS, your customers, etc.), but 100% certain the blatant nonapology is better skipped in the future.
