The Programmer Time Quanta

Different kinds of work have different time quanta. Someone proofreading a manuscript could probably be interrupted every fifteen minutes with little loss of productivity. But the time quantum for hacking is very long: it might take an hour just to load a problem into your head. So the cost of having someone from personnel call you about a form you forgot to fill out can be huge.

This is why hackers give you such a baleful stare as they turn from their screen to answer your question. Inside their heads a giant house of cards is tottering.

The mere possibility of being interrupted deters hackers from starting hard projects. This is why they tend to work late at night, and why it’s next to impossible to write great software in a cubicle (except late at night).

Vitreous: a Transparent Portfolio Manager

VitriousWhen one friend asked to me for install for her a copy of Indexhibit on my server I was wasting a bunch of mails trying to understand why she wanted this creepy and unusable portfolio manager. One of her arguments was: because one friend told me that it is a ‘transparent portofolio manager’, at this moment I thought: ‘alright so it has to be something that runs on your computer and synchs your portfolio contents from your local hard drive to the online application’.

That was awsome, but this wasn’t what Indexhibit is.

Since this moment I was looking for the moment to develop by my self the kind of ‘transparent portfolio manager’ I was thinking on.

The result is still inside of my fingers but for the moment I have an experimental version ready to work: Vitreous.

Vitreous is a simple Ruby + Sinatra + Dropbox API application that looks on your Dropbox online folder and builds a simple web site with collections and items.

Using simple tricks you can: short the collections and the items, add a description text for each item, configuring home image and description.You can manage your portfolio just creating folders on your local hard disk and adding images to them. Dropbox and Vitreous will do the rest.

The next step is to build a multi user application so you will be able to open a Vitreous Portfolio just introducing your Dropbox Api Credentials on an online form. Multiple portfolios for unique user, template system, auto cache refresh,

…(I am still a few angry with the Dropbox API… I hope they will move forward soon).
