fjw··on Show HN: Tidery – recurring payments for non-programmers
Thanks! Still finalizing the payment details: I'm thinking about offering a choice between paying a flat fee and taking a fee. Would love to learn more about your specific situation: can you email me (email's in my profile)?
fjw··on Show HN: Tidery – recurring payments for non-programmers
Hi HN!

Tidery is a simple tool that makes collecting recurring payments easy. In less than five minutes and without writing any code, you can set up a page to start automatically charging customers on a recurring schedule (handled securely via Stripe).

Here's an example page for a student organization I help run (we're experimenting with this idea): https://tidery.com/yhack

I think this problem has become relatively manageable for developers, but still isn't as straightforward for non-developers or for people who want to test ideas quickly. I feel like this could open up a lot of creative exploration -- for devs testing out MVPs, for creatives to sell new products, for organizations to set up recurring tip jars or memberships, and more.

Would love to hear what people think!

fjw··on Show HN: Scribesend – Stripe for accounting
Apologies on the delay. My thought was that items with the same tax rates could be grouped together in the same account so the tax rate doesn't need to be passed in when creating every entry. Does that make sense?

Thanks!

fjw··on Show HN: Scribesend – Stripe for accounting
Hi Jeff, thanks for the questions!

1. A lot of the existing services are clunky and their API offerings are hard (though not impossible!) to use -- making them hard to interface with online applications. But for the most part, these are accounting software suites designed for a general audience, with an API offered. If you have a lot of microtransactions to process, or your application requires some financial logic baked in (gift cards, marketplace payouts, detailed account receipts for a insurance/co-pay splits, etc), having an API can help greatly.

Additionally, our API is being designed with specific developer use cases in mind: general use cases like subscription billing, sane integrations with payment gateways like Stripe and Braintree, online invoicing, and tax reporting will be designed around online businesses and Saas applications. Again, software like QuickBooks is designed to be broadly used, and thus, may be harder for you to get started in (especially if you do not have an accountant handy). The API will always support general use (you can do whatever you want with the API!), but developer abstractions will be top-of-mind.

2, 3. I hear you and thank you for the concerns. These are all things that definitely need to be done before opening the product up.

4. Here are some benefits I see:

- real-time financial stats that are updated as the transactions are made, and not just whenever the transactions are reconciled — and can be used (and understand) by everyone from the CFO to the accountant to the engineers

- generate real-time account statements for users, just like your bank is able to provide you — you can control how much data you show to users using your own internal business logic

- a secure financial data store that you can send GET requests to whenever you need the data. Examples where I see this doing well include in-app currencies and credit systems, gift cards, managing marketplaces and seller payouts, managing receipts, showing users detailed account statements, sales tax management, etc.

- write scripts, perform analytics, and use the data/certain subsets of the data as you wish — it'll be much easier to export and analyze this data than with other software

- saves you engineering time from building your own financial infrastructure, or trying to hook it up to other accounting software suites

Also, more reporting endpoints (http://scribesend.com/docs#reports) will be added soon!

Obviously, we're not 100% of the way there yet, but hopefully this clears things up a bit.

fjw··on Show HN: Scribesend – Stripe for accounting
Hi, thanks for the comment! Taxes have not been added in yet, but will probably be a percentage value in the accounts object. This will then be used to automatically generate sales tax reports.

Friends/potential customers haven't asked for taxes yet so not all (crucial) features have been added in just yet. That's what this post is here to expose :) Are there any other glaring omissions you see?

Not a parody, but it did actually start out as a joke!

Super cool! Would love to hear more about your self-publishing experience -- mind if I shoot you an email?
fjw··on Show HN: Amazon Instant, weekend project
Thanks, changed! For some reason I originally used max-height and a fixed width.
fjw··on Show HN: Amazon Instant, weekend project
:( Well, I'm planning on open-sourcing it after I clean up the code, so you could check it out then.
fjw··on Show HN: Amazon Instant, weekend project
Oops, personal oversight! Thanks, added it in.
fjw··on Show HN: Amazon Instant, weekend project
I think it would be really interesting to download the entire listing and watch how volatile everything is, especially the item prices. Searching would definitely be much faster as well.

Thanks for checking it out and thanks for the suggestions!

Check out Amazon's Product Advertising API: https://affiliate-program.amazon.com/gp/advertising/api/deta...

It supports Item Lookup, Item Search, Cart Creation, etc. Pretty cool!

fjw··on Show HN: Amazon Instant, weekend project
Good question -- it's not really solving anything, it's just a different way of viewing Amazon products in a slightly more slick interface. It might save you a few seconds on a search, or it might not.

I mostly just wanted to play around with the Amazon API and AJAX calls. Thanks!

fjw··on Out of 15M brackets, none remains to win Warren Buffet's $1B March Madness bet
Looks like the final perfect bracket (even though it's ineligible for the Billion Dollar Challenge) is about to be busted anyway with VCU on the verge of beating S.F. Austin.

edit: March Madness.

fjw··on Add search to your Jekyll blog
I like this approach a lot. If you have hundreds or thousands of posts, it would also be pretty easy to only append new posts to the JSON file instead of regenerating the entire thing.

fjw··on Ask HN: If you would launch a website in 4 hours, what would it be?
Have you thought about just using Wordpress? You can be the admin and then make a contributor account for your daughter to write random things but not have the power to publish them or change up any of the settings/design.

fjw··on Lessons Learned from Going "Profitable" in Under an Hour
A local store offered to print the designs in full color on high quality cotton shirts at an exceptionally low price. We contacted many providers to try and find the lowest possible price and we were fortunate enough to gain their support.

If you're interested in details, it was Campus Customs in New Haven, CT. http://www.campuscustoms.com/

fjw··on Lessons Learned from Going "Profitable" in Under an Hour
Once we addressed the initial concerns, people were much more willing to donate to us and we raised around $1500 in the first three weeks. After that, it was just a matter of packaging and shipping out the t-shirts.

Author here, I really like what you're doing for Newtown. Best of luck to you with that!

As far as the press goes, you're definitely correct about other reporters reaching out. My main point there is that we found more success by personally contacting people (press included) about what we were doing, rather than sitting around, waiting, and hoping for them to come to us. We badgered newspaper reporters and called local TV stations to make sure that we were being talked about and that people knew how to get involved with our relief effort.

Honestly sounds no different to me. It's probably better to go with the single S in Founder Stash.
fjw··on Show HN: Shirts for Sandy - Raising money for the relief fund
Hi HN! I know this isn't the usual HN project, but I remember seeing something like this posted for a snowstorm a while back. I'm in CT and since I was locked in my college dorm yesterday as Hurricane Sandy made landfall, I decided to get some like-minded people together and design and sell a T-shirt to help the relief movement as the storm continues its path. We will be donating 100% of our proceeds to charity (currently we're looking at AmeriCares[1], but please let me know if you have any suggestions).

Technology wise, I set the entire thing up in a couple of hours with a static page and put it up on an AWS S3 bucket. We're collecting the orders in a PayPal account now to build up a large order and then getting our shirts printed, allowing us to minimize our printing costs as much as possible.

We're selling our shirts for $14 (free shipping) at http://www.shirtsforsandy.com. Even if you can't buy a shirt, we would greatly appreciate it if you donated a few spare dollars to the relief effort or if you could spread the word about what we're doing. Our Facebook page is at http://facebook.com/ShirtsForSandy.

There actually is a way to redirect requests on GitHub Pages. It's a bit hacky, but if you want to stick with GitHub's hosting, it might be worth doing.

You can manually create a new page "index.html" in the corresponding subdirectory for your redirect. If you want /post/oops-i-made-a-tpyo to redirect to your updated oops-i-made-a-typo link, you would create /post/oops-i-made-a-tpyo/index.html and make an HTML redirect:

  <meta http-equiv="refresh" content="0;url=/post/oops-i-made-a-typo/" />
You can see this at work on my blog [1] and the code for the redirects I made [2] when migrating from Tumblr.
