A fragment to let Unix boxes (and Mac OS X) know that this is a python script:

1

#!/usr/bin/env python

Add at the start of the script.

Make sure the script is executable with:

chmod +x scriptname.py

Some Mac OS X stuff…

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

To install Homebrew. You might argue that downloading and executing arbitrary ruby scripts is a tad dangerous. But then so is downloading and executing some bin. (With scripts you have the benefit of being able to examine the source before you download, but watch out for a bait-and-switch if someone decides to show your browser different content because they detected a specific user-agent.)

Now let's grab wget:

brew install wget

You see, just like apt-get (or Chocolatey).

Now we'll use wget to grab stuff from a NAS:

wget -m ftp://usr:pass@server/path/to/files

(Why aren't we using SMB? That's a long story but essentially it's an old NAS and a recent Mac OS X build.)

If I don't want to include the source directory structure in the target add --cut-dirs=4 where 4 is the sum of the number of directories specified in the path +1 (for the server name).

I was trying to figure out what to do with the nasty weeds (Ground Elder and Bind weed). I didn't fancy burning, and regular composting is liable to just spread the stuff wider. Someone mentioned liquid composting, i.e. rot the stuff and use the liquid as a fertiliser.

I'm trying it.

The nasty weeds along with other green garden waste (including some grass clippings) go into a water butt. Water gets added. Things rot down. The liquid fertiliser can get drawn off via the water butt tap. At some point I'll need to empty the solid stuff. I'm hoping that if left long enough (how long?) that'll be an okay addition to the regular compost.

Same person from @BTCare. Sorry to hear still slower than before. I checked speed while on the call (~4.4mps down). She wanted to check something, called back 10mins later with:

Test show that there's a mismatch on the supplier side. I'll escalate, normally 48hrs turnaround, but I'll check tomorrow

So, we wait some more.

Update: 24/10/2014

Lovely engineer. Line is okay (but replaced master socket to one with integrated filter). Cabinet port is also okay, feed from DSLAM in fibre cabinet is gving rated 40Mbps but this falls to 4-ish by the time it reaches us. Can't check the fibre cabinet though ("that's another bit of BT, BT wholesale").

Now need to wait 10 days for the line to stabalise. Then, assuming no change, will need to choose whether to go back to ADSL or possibly try the 80Mbps feed from the DSLAM because "that might give you *-ish by the time it reaches you".

Update: 16/10/2014

A nice person from @BTCare called. They predicted 9Mbps, so will send an engineer to check.

• Initial mesaurements: line speed download is slower than before upgrade. Latency is increased. Upload speed is higher

BT are upgrading the broadband today (Friday). Or at least they've scheduled an engineer to. Let's use their tools for data gathering: BT wholesale speed test

Observations

• Three step process:
  • on premisis replace BT master socket (chip platser, fix previously used faceplate...)
  • nip to cabinet, flip over to fibre
  • return and configure line / Home Hub 5 (HH5)
• "Will take ~3 days for line speed to stabalise"

Notes

• HH4 == BT Home Hub 4
• Dirty: other stuff happening / other devices conected on the network
• Clean: just the test site, all other devices disconnected (easy to do, because the current BT HomeHub4 is just the modem. WiFi and Ethernet networks are through another router).

• Network configuration for Studio:
