My little corner of the web
I seem to always get in a bit of a muddle with the terminology and which sensor goes with which kind of input. This is the most comprehensive and accurate document I’ve found, so I’ll be using it as quick reference from now on.

I’ve been playing with QGIS, and it’s an awesomely powerful piece of software for map making an analyzing geographical data.
It has the ability to show HTML map tips when you hover over certain features, but with some restrictions.
The containing box (which you can’t style, AFAIK) has
The maximum size of the box is limited to half the size of the graphics area, which means scroll bars appear within the map tip if the content plus the padding and border would make it bigger than that.
I was a little confused by how units work in Draftsight, so now I think I’ve figured it out i thought I’d share.
They key thing to understand is that that the model, ie. the lines you’ve drawn, isn’t in mm or inches or feet, it’s just 1 Draftsight “unit”. When you change the settings related to units, nothing happens to model, it just changes what you see on the screen (in various places, like the cursor position in the status bar, or the length & co-ordinates of lines in the object properties).
The key setting is under Drawing Settings -> Unit System -> Length -> Type. Lets’ go through the options:
Special handling is required for blocks because two designers could both draw something in different units. Alice draws in cm (ie. 1 draftsight unit = 1 cm) and Bob draws in inches (1 draftsight unit = 1 mm). If these drawings were simply combined without consideration of this, the scale would be different and they couldn’t be used together.
To get round this, Draftsight makes a record of the units when you create a block. The default for this is set in Drawing Settings -> Unit System -> Units Scale -> Block units format. When Alice creates a block, Draftsight records that unit in the block, so whenever it’s used Draftsight knows that 1 draftsight unit = 1 cm.
When Bob is drawing, he has the setting set to “Inches”. If he inserts a block made by Alice, Drafsight will recognise that his setting is different from the value stored in the block and scale it by the correct amount (2.54 in this case).
Dimensions deserve a mention while we’re discussion units. The key settings is Drafting Styles -> Dimension -> Linear Dimension -> Format. This has the same options as the first setting discussed above. This can be overridden on a per-dimension basis in the properties for the dimension.
If you want to copy a complete folder structure, but not the files contained in it, use robocopy from the command line:
robocopy "A:\Source folder" "B:\Destination folder" /e /xf *
This is lifted straight from https://superuser.com/a/873585/178934, I’m just putting it here for my quick reference.
A quick reference, this is far from authoritative or exhaustive but intended to be used a go-to unless you have better information:
| L1 (Hot 1) |
(Hot 2) | L2 | L3 | N | PE | ||
| Europe | Single Phase | Brown | – | – | – | Blue | Green / Yellow |
| Three Phase | Brown | – | Black | Grey | Blue (if present) |
Green / Yellow | |
| USA | Single Phase 120 V | Black | – | – | – | White | Green or Bare |
| Split Phase 120/240 V | Black | Red | – | – | White | Green or Bare | |

Like this:
dir -Directory -Recurse | % { $_.FullName } > list.txt
I don’t like the default for SpiderOak’s –purge-historical-versions command, which does this:
This allows you to remove historical versions of files in your backup set according to the following schedule, which is to keep one version per hour for the last 24 hours, then one version per day for 30 days, then one version per week thereafter.
So here’s my own version, which does:
On Windows
"C:\Program Files\SpiderOakONE\SpiderOakONE.exe" --purge-historical-versions h24,d30,w8,m --verbose
On Linux
SpiderOakONE --purge-historical-versions h24,d30,w8,m --verbose
This is a simple script to crop a plugin with fixed dimensions – I used it to crop out the window border from a VNC Client connected to an industrial touchscreen.

Save in the gimp scripts folder, something like C:\Users\JoeBloggs\.gimp-2.8\scripts\ on Windows, or /home/JoeBloggs/.gimp-2.8/scripts/ on Linux.
It will appear under Filters > Custom
Editing MusicBrainz data can be intimidating at the best of times, but Classical recordings can be particularly tricky, as the 4 different “Artist” fields can all be different.
Hopefully this quick reference guide should avoid a few more mistakes in future.
