Published on 2012-09-12 10:01:03

The War You Don’t See investigates the complicity of media in distributing propaganda, failure to investigate claims made by authority figures and willing dismissal of information that does not suit the pro-war narrative in the modern era. http://thepiratebay.se/torrent/6042414/John_Pilger_-_The_War_You_Don_t_See This is one of John Pilger’s finest works, I’m particularly fond of how he makes interviewees of

Migrate a Virtual Machine from Full Disk to Single File-System Image

Full-disk images – that is to say a file containing an MBR, partition table and one or more partitions – are a pain in the arse to scale. Conventional wisdom tells us we should be able to do this with losetup and parted, or less gracefully with (c)fdisk but I’ve never had anything but trouble.

I Schooled CoreNetworks.net

I was considering CoreNetworks.net after my crummy experience with iWeb last week because I had a dedicated with them once upon a time and their support team was really fast and courteous. I know someone personally who has been with them for three years and the reviews around the web generally concur that the support

Nine Web and Server Hosting Providers I Hate

Published on 2012-04-04 21:51:59

I’ve had a lot more crummy experiences with web hosts, collocation and dedicated server providers than I have glowy, happy ones – as seems to be the case for most everyone in this industry subject to a budget. For your benefit (and my therapy) here are some of the crappier ones I have had the

PayPal Here is an exciting new feature PayPal will be launching in Canada soon that promises to bring credit card processing (and, naturally, PayPal payments) to merchants who are under-serviced by traditional Point-of-Sale transaction processing.

This American-South-meets-Canada dish is delish and succeeds at offending all three major religions! Not only will we be cooking with pork it’s going to be virtually poached in dairy for bonus points.

Always Test the RAM on a New Server!

Don’t expect your provider to do it for you! I ran into paging errors on bootup with the monolithic 2.6.38 paravirtualized Xen kernel I published here and have been using without issue for over three months on a new dedicated server with a similar dom0 software configuration as the one it was compiled for.

“Anonymous” Threatening to “Shut Down Internet” March 31

Published on 2012-03-28 16:35:27

Apparently some among legion want to DRDoS the root name servers with the same sort of UDP-spoofing DNS amplification attack I have had personal experience defending against. I’m not going to get into how horribly misguided this is, how negatively this is going to affect the cause’s image or some long-winded speech on ethics. I

Testing Download Speed and Latency with AJAX

Published on 2012-03-21 22:46:54

I came across this script while looking for something that would let me quickly determine a user’s download speed. I’ve improved upon it by detecting latency (and HTTP header overhead) then subtracting it from the total time of the bulk download to yield more accurate results. You must supply a large file to download, the

I’m among the thousands who have watched the recently distributed Kony 2012 film and like many of its viewers felt briefly compelled to help carry out its sole objective: dissemination. I would be a hypocrite to help propagandise; I’ve never really cared “enough” about the plight of Africans and to start pontificating now would be

Replacing a Ceiling Light Fixture

For obvious reasons I didn’t like the stock fixtures in my bedroom: Or my bathroom: Because crappy fixtures take all the swank out of X10 dimmers. We can see there was some buggery in here to get the bathroom fan running in series with the light (which I fixed the other day). The box is

The last goon who lived here ripped the surface-mount toilet paper roll holder out of the wall. These holes are easily cleaned and filled in with spackling paste. Cut any of the paper fluff from around the edges of the holes at an angle so that the hole is tapered inwards. Unfortunately, bigger holes require

A little over a month since the release of the Megaupload Song New Zealand police have arrested co-founders Kim Dotcom and Mathias Ortmann along with two of their underlings today. Some irony at play in that yesterday was Wikipedia/Reddit/etc’s annoying-but-effective SOPA protest/blackout. Federal prosecutors have accused it of costing copyright holders more than $500m (£320m)
