I honestly have no idea what this is. If I didn't find this via HN, I'd immediately assume it was some scam for phishing Dropbox accounts. You need some information here about what this thing does.

Reading the comments below, I see that you're well aware of this. I would suggest just adding a single huge sentence at the top of the page that says "by you giving us X information, this web app will do Y". No need for fancy graphics, slogans, etc, just something simple that explains what it does, in a short, effective sentence.

Yeah that's a great point. I added such a sentence. The site you visit is actually located on my Dropbox so nice and easy to edit.

I mean I basically made this because I wanted to start making a old school type of personal web site (80cols.com) and didn't want to have to scup files all over the place. I also didn't want to use an existing blogging platform. The major disadvantage is you can't run script or anything, but it's great for serving static content. I mean I could basically load gigs of videos and photos and just share them with the world if I wanted.

I need to do more, but at least now I know there's interest. I didn't even know that before launching.

Yup, the copy was non-existent.. I've been updating the copy tonight after I fixed some troubling oauth bugs.

I didn't realize you ultimately throw away your first oauth key, and keep the second oauth key.

iradik, now that I've read your explanation in the comments below I want to say I love the concept. A very cool way to almost instantly throw a site online and update from anywhere.

Of course I have to agree with everyone saying "what the heck" based on the homepage. Maybe just add a "what does this do?" section to start, and be sure to describe what fields like "subdomian" actually are for.

The other major hurtle here I think is simply fear of having our Dropbox data or account stolen in some way. I'm not claiming that is in any way what you are doing, but it's a natural immediate thought, particularly for this techie security focused audience I suppose.

Either way, I really do love the idea. You might want to fix up the homepage and see if the MVP gets some traction.

Dropbox has two modes: APP_FOLDER and DROPBOX. APP_FOLDER just creates a sandbox and does not give me permission to all your Dropbox data. I would never want access to such a thing on a server that's publicly visible.

The Dropbox authentication screen says: "This app will create a folder named webcache in your Dropbox. The app will only have access to this folder." But yeah you have no idea what's going to happen when you click that grey Submit button.

I agree the lack of polish makes it look spammy. Maybe some rounded corners and bubbly clouds would make it more trust-worthy. Along with an invitation to come over my house and have a beer.

If found this intimidating on the first read: "By you giving us a subdomain and ...".

I don't want to give you a subdomain! How about "Enter the subdomain name you want:". Or something.

yes i'm realizing there's nearly nothing approachable about this ui as simple as it may be. glad hacker news visitors are so friendly and giving such great feedback. i really appreciate it.

i'm also seeing lots of errors in the server due to authentication reasons, clearly i have some learning to do in terms of how oauth actually works.

yay found the oauth bug! I hadn't learned oauth, but now I have.

I'm also a fan. There's something powerful in its simplicity. As far as MVP's go, this is tops - look forward to seeing where it goes.

What's the advantage over the Dropbox "Public" folder?

You can use your own domain. It's not advertised but if you enter xyz.yourdomain.org and point a CNAME to 80cols.com it will host it for you.

It's faster, supports index.html, and directories. I've found public links to be slow. Additionally it's extensible because it's running on an http core I can modify.

Hi iradik.

I put together a 5 minute review of your software specifically looking at the usability of it.

I hope you find this useful.

Hello again iradik.

I've put together a second review of your updated app. Again, I hope you find this useful.

there is no way to deactivate

You can delete the folder, but I agree there are no settings and no login. In fact there isn't even a database, which is a problem if I have to restart the server. I am pretty sure I can easily reconstruct from the logs though.

You can email me, not a great solution I know. You can revoke access in your Dropbox account.

You need a paragraph explaining what this is.

Definitely agree. I'm putting together something now. I think some screenshots along with a video would go along way of explaining what happens after you click submit, which I'm thinking is what visitors are wondering when they get here.

ok updated.. this is what site originally looked like: http://webcache.80cols.com/orig.html for comparison.

Much better!

i learned plenty making this. varnish, httpcore, and the dropbox apis are all very cool.

though clearly i need to learn how to make an effective landing page, because no one who is visiting actually trying this service.

It's not clear what we're doing on the landing page.

What is the subdomain? A subdomain of your domain? I'm assuming that, but I don't know...

What will happen when we connect our dropbox? Is that even what the submit button does?

Just some thoughts... great work otherwise!

This. I was really confused as to what was happening.

If you enter "foo" it will create foo.80cols.com for you and create a folder in your Dropbox called Apps/webcache/foo.80cols.com and host it.

If you enter "www.yourdomain.com" it will work too, though you need to setup a DNS CNAME record and point it at 80cols.com.

Clicking sunlit links whatever domain you enter to a folder in your Dropbox account called Apps/webcache/www.yourdomain.com/

Then whatever you put in that folder will be automatically synced to webcache and hosted within a minute. As you update the folder it will sync within a minute. Unfortunately Dropbox does not have a push API so I have to poll Dropbox to check if your files changed. Otherwise it would be faster. Dropbox has an rss even feed but it's not really designed for programmatic access and I would need to ask the user to provide it. Supposedly an events API is coming; that would be very cool.

iradik replied to your comment but his reply is [dead], FYI.

Why is it dead?

You submitted two identical comments. When that happens the second is automatically killed. But meanwhile you noticed and deleted the first. I just unkilled the second.

Trying again...

Do you cache the file on your server? Or just fetch from Dropbox every-time?

It's cached on my server using varnish http://varnish-cache.org, which uses LRU caching with ttls. A very cool open source web caching project. I use a configuration very similar to media wiki where I set long ttls and then have the backend send a PURGE http message followed by a GET to varnish when a file is updated to refresh the cache.

I've point briefly looked at the Dropbox API, but couldn't figure it out; how do you detect when a file has changed?

There is no push api or list of changes at this point. You can check each directory to see if it's changed... by passing a hash to the metadata function. It will tell you if the directory has been modified in any way.

What are you doing to prevent this from being abused by spammers?

Nothing. It's a great question though. What do normal web hosts do to prevent such things? I suppose I would have to do something similar.
