Brilliant second issue. Your style seems to have settled down a little, which is a good thing. It is very difficult to read on the Issuu site, but fine when downloaded. Can you allow Issuu to show a single page at a time? Here are some brickbats on the draft:
The Question on the Resize partitions page: It may not be a good idea theoretically to run sudo on GUI programs, but it wont be a problem in this case. The question is worded badly anyway since it reads as if running any GUI program from the command-line is bad and that is very definitely not the case.
Some or many laptops which have built-in SD card slots seem to have a problem writing images to them. I have no idea how widespread this is or if it affects gpartd or a live Linux CD. I have a feeling it might. I know I failed to write an image on my Windows 7 Dell laptop when it worked fine when using an external card reader.
How to start a graphical interface:
There is a spurious power icon in the picture that should appear in the text.
There's an xkcd strip that explains this better than a thousand words: http://xkcd.com/149/
I have no idea if you would be allowed to use it, but there's no harm in asking.
Stop the press Exclusive interviews: horrible colours
Pisection: The 2V5 regulator is labeled as ADC reference. Maybe it is right, but there is no accessible ADC (analogue to digital converter) on the RaspPi (maybe it's for the composite video or something). Might be less confusing to omit the ADC reference reference.
Computer Music: Horrible green colour for stuff to type in. You haven't used this style elsewhere, and if you decide to use it you need to darken it.
In Control: The article is incomplete. (I assume you know this)
No indication how wires would be connected to the GPIO pins. Crocodile clips might be the best bet.
Most resistors these days have five colour bands, not four. A 1K resistor would be brown-black-black-brown---red, meaning 1-0-0-x10---1%. The diagram shows brown-black-red---gold, meaning 1-0-x100---5%. The problem is of course that just describing that is another page.
I haven't seen a Tandy in ages; Maplin would be a better bet. Those breadboards are ubiquitous.
It's a long article, it's going to be longer and it could profitably be longer still. Might it be a better idea to just use an LED and resistor and get to switches next month? You could "test" the LED by connecting it to 3V3 and then move it to an output pin and drive it from Python.
Command-line clinic: The "above example" assumes nothing about the hard-drive name. Was this an example that got changed?
Debian: This is the only article that references running a VM. Does it need to?
Have you considered standardising on a Python IDE?
Scratch Patch: I assume this is a place-holder?
Python Pit: The music-ruled paper is anachronistic and text on it is difficult to read. At least kill the bold and consider using a monospaced font. YMMV
Letters: Wow! I got published!
