Discussing the current state of video-capable DSLR cameras

Note: There's a summary for the impatient!

In August 2008 Nikon released the D90, the video DSLR that shot HD video.

The concept was apparently aimed at news-gathering, where reporters who would usually have to carry both a DSLR for photos and a separate video camera, could instead carry a single device capable of both shooting stills and, at the press of a button, shoot HD video.

For completely different reasons, these VDSLRs also appealed to film makers - a wide range of changeable, affordable lenses and large sensors capable of creating "filmic" shallow depth of field.. but, film-makers and news-gatherers have very different needs, and all VDSLR's thus far have been, in various ways, broken..

I spent a bit of time making a nice conky configuration for my amusement. I thought I'd share.

Preview:

After restoring a backup, the various OS X system folders became visible again (such as /bin /mach_kernel etc)

The following command (adapted from this post by Wowzera) will hide them again:

# Hide sym-links
SETFILECMD="/Developer/Tools/SetFile"
for cdir in /etc /tmp /var;
    do sudo $SETFILECMD -P -a V $cdir;
done
 
# Hide directories
for cdir in /bin /cores /mach_kernel /private /sbin /usr /Volumes; do
    sudo $SETFILECMD -a V $cdir;
done

Launch Terminal (in Applications, then Utilities), and paste the above script.

Introduction

Hashing normally makes people think of cryptographic hashing often used to store passwords. Understandable considering this is what users might more familiar with. However, the principles of hashing are used for more than simply preventing retrieval of certain data.

What I'm referring to is hashing for the purposes of efficient data referencing. This is better known to developers rather than users.

This is simply a "click these buttons" guide to git. See the last section of the article for more advanced/better guides and resources.

Installing

This file is a utility script for building an executable script that users of the Windows operating system can double click on to start their Python application. This utility can be especially useful if your Python application does not need to display the command prompt.

I hope somebody will find this useful :-)

To print some information every 10 loop iterations can be a bit messy. Given the following, simple loop:

for x in lots_of_stuff:
    process(x)

The "dumbest" way would be:

i = 0
for x in lots_of_stuff:
    process(x)
    if i % 10 == 0:
        print "Some progress info"
    i += 1

A more elegant solution would be to use the enumerate built-in:

for i, x in enumerate(lots_of_stuff):
    process(x)
    if i % 20 == 0:
        print "Some progress info"

Much nicer, but this doesn't work with while loops

After a frustrating development cycle we're back. With a new site. You may not notice many if any changes. It's mostly been fixing problems back-end with the system and putting in new features for our members. We do now have some public features that should make things more interesting. Including the projects pages!

The site layout will remain the same for the time being as I have too many other projects to be getting on with.

The redevelopment of this site and it's mini-site is nearly finished.

Hopefully over the next couple weeks we'll finish up and we can start the roll out. Stay tuned.

Just something I was playing around with today that I thought I might share.

I was curious about how to get network statistics in windows so I've been reading MSDN all day trying to work it out. I've written a little bit of python using the ctypes module to access the API on network statistics. All I can say is that doing these things on Linux is so much easier as you can just access the /proc directory and parse the system files there that contain such information.
