Quickly Publish Photos on the Web with Photocrumbs

Jul 29, 2013 GMT

Usually, I use my Pygmyfoto application to publish photos on the web. But there are situations when I need to quickly share a bunch of photos with a minimum of fuss. Inspired by the Loading images from a directory with PHP article, I whipped up a slightly more advanced version of the original script. For lack of a better name I dubbed it Photocrumbs. The app consists of a PHP script which does most of the work and a handful of helper files. Besides scaling photos and displaying them as a continuous stream, the script also extracts basic EXIF info, such as aperture, shutter speed, ISO, and date. Installing Photocrumbs is a rather straightforward affair, and you'll find installation...
Generate a Static Blog in Seconds with blogpy

Jul 24, 2013 GMT

Static site and blog generators are all the rage nowadays, and understandably so. With a static generator, you can author articles in your favorite text editor using a lighweight markup, and you can serve your blog even on modest hardware. Also, you don't have to spend time on installing, configuring, maintaining, and learning a full-blown CMS. The latter is especially true if you opt for something like blogpy, a super simple static blog generator written in Python. Although blogpy lacks the bells and whistles of more advanced static generators, it's perfectly suitable for maintaining a no-frills blog.Before you install blogpy, make sure that Python 2.7 and the python-markdown package are...
How I Use My Raspberry Pi

Jul 23, 2013 GMT

Inspired by the Things I Do With My Raspberry Pi article, I thought I'd share with you how I use my Raspberry Pi. Actually, I use at least two Raspberry Pis on a regular basis: one serves as a hacking and prototyping platform, while the other one acts as a server on the local network. The latter performs a variety of tasks.File ServerI connected two external USB hard disks to Raspberry Pi via a powered USB hub. The usbmount utility takes care of automatically detecting and mounting the connected disks at the /media/usbX mount points. One disk is used for storing all files and documents, while the other one is reserved for rotating backup. I don't use any dedicated file server software to...
Turn a Browser into a Scratchpad

Jul 17, 2013 GMT

Transforming your browser into a scratchpad for jotting down notes is as easy as entering the data:text/html, <html contenteditable> line into the address bar and hitting Enter. There are a lot of variations of this simple trick, and you can find a few of them in a thread on Hacker News. I use a slightly modified version of Writability: data:text/html;charset=utf-8, <title>Scribbles</title><body OnLoad='document.body.focus();' contenteditable style="font-size:21px;line-height:1.6;font-family:'Alegreya',Alegreya;max-width:21em;margin:0 auto;padding:3rem;background-color:rgb(233,233,225);color:rgb(68,68,68);" spellcheck="false">This solution...
Miniflux: No-frills RSS aggregator

Jul 15, 2013 GMT

The demise of Google Reader rekindled an interest in self-hosted open source RSS aggregators. NewsBlur and redmine/projects/tt-rss/wikiTiny Tiny RSS are probably the most powerful among them, but these two RSS readers are not the only fish in the sea. For those who are looking for a no-frills and dead-simple to deploy RSS reader, Miniflux might be just the ticket. Despite its minimalistic nature, Miniflux is a rather capable RSS aggregator that packs a few nifty features. The application's interface is designed for readability, and it works like a charm on mobile devices; hence you don't need a dedicated RSS reader...

A journal application can be used for a variety of purposes: from keeping track of things you've accomplished to jotting down notes and ideas.

Got an Android device? Want to use it as a screen and keyboard for Raspberry Pi? A simple trick described in a thread on the Raspberry Pi forum site can help you with that.For this trick to work, you need an Android device that supports USB tethering and VX ConnectBot app installed on it.
