My Inner London Shack

I did a little tidying up and rearranging of the shack, so I thought I should post up here in some form of attempt to try and keep updating here. Of course, when I say shack, I am in a flat in the middle of London, so where some folks have entire rooms/converted garages/sheds, I have the top of a set of shelves…

Despite this, I have managed to work JT-65 out into Europe/the fringes of Russia/Kazakhstan with 5W from my Yaesu ft-817 and my recently acquired AlexLoop Walkham, which I am quite pleased with.

I have also been playing with some APRS, using both my ft-817 and my trusty baofeng UV-5R with a mobilinkd bluetooth TNC, and APRSDroid on my phone, as well as setting up a receive only iGate using an RTL-SDR and a raspberry pi.

The things I haven’t been as active with are amsat work, and either VHF analogue or any DMR work through my openspot, so I am going to set myself a goal of making my first amsat QSO by the end of April, and also try to get into the habit of at least monitoring my local repeaters and/or some DMR talkgroups.

That and replace the windows surface in that (terrible) photo of my shack with a raspberry pi with a seven inch touchcreen, hopefully running my APRS iGate, wsjt-x, GNU predict for amsat work, and whatever else I can think of to punish my poor overworked pi.

Create SES users in the SES console, not the IAM console

Having spent some time this morning getting annoyed by Amazon’s SES returning “535 Authentication Credentials Invalid” for what I knew were valid credentials when trying to send email via the SES SMTP interface, I am typing this up here to make sure that I remember it for the future.

Requirements for sending emails:

Create the user in the SES console, not the IAM console, even though the SES user will show in the IAM console once created. Because obviously.

Base64 encode the access key and secret key, but don’t just do

echo myvoiceismyaccesskey | base64

because that is too obvious 😉 Better make it

echo -n myvoiceismyaccesskey | base64 -w 0

Fuck yeah option flags 😉

My Magic Chilli

I’ve had at least one person ask me about my chilli recipe, so here goes. It is largely a choose-your-own style adventure, but I’ll try to give the basics, and will be giving away my little secrets. For reference, I usually cook this in “a git big pot”, or, to put it another way, a “deep casserole” pan, which is either four or six litres. I’m not sure, and I can’t be bothered to go downstairs right now to check. (That, right there, is the sort of dedication to blogging which leads to sometimes two whole posts per year).

Ten characters to save hours of hassle

We’ve recently been making some security minded changes at work, one of which is ssh-ing though a bastion host/jumpbox, and me, being one of those linuxy types, had some hassles with my ssh working. I was getting errors where both sides of the connection claimed that other one had closed the connection, and some mumbles about pre-auth.

After a lot of time wasted googling, and trying things like limiting the ciphers used, dropping to a 2048 bit key instead of a 4096 one, trying keys without passphrases, I managed to stumble on the ten characters which fixed my connection, and allowed me to ssh with a snippet in ~/.ssh/config via a bastion host

ssh-add -k

Yup, I forgot the number one rule of computering, which is stop trying to find the most elaborate, complex solution, and start with the easy steps.

It might be annoying, but this is why computer people ask if you’ve restarted/reloaded things 😉

I won a thing!

 

London Hackspace Radio Club - RSGB National Club of the Year 2014 (large club section)

London Hackspace Radio Club – RSGB National Club of the Year 2014

Well, technically I was a small part of a club which won a thing, but in the last year I’ve been doing something which I wanted to do twenty years ago, but for whatever reasons didn’t, and I’ve been getting into amateur radio, starting with my foundation license in April 2014, and moving up to the intermediate license in April 2015. And no, I’m not planning to wait until April 2016 to get my full license, although now I look at it, there is something nice about the progression being every April.

Anyway, at the 2015 RSGB AGM, the London Hackspace Radio Club ( callsign M0HSL ) were awarded the RSGB’s Club of the Year 2014 (Large Club Section) award, which was nice, and thanks to the RSGB and their CC-BY-NC-ND licensing of the photographs taken at the award ceremony, you lucky lucky people get to see this here picture of the representatives of the LHS Radio Club being presented with the award, kindly sponsored by Waters and Stanton.

A thing about porn (oo-er)

Before I start, don’t bother with any of that “ew, sex, icky” nonsense. We’re all grown ups here, and we can acknowledge that people do sex stuff. The vast majority of them even enjoy it.

First they came for the pornographers, and despite what Pastor Martin Niemöller said, I *am* going to speak out.

You might have heard about the Audiovisual Media Services Regulations 2014 (AVMS Regs 2014) which came into force on December 1st. In a nutshell, a faceless quango has decided that various acts which consenting adults are perfectly within their rights to perform are now illegal to depict on film in the UK. It’s obviously not that simple, but follow the links after the jump to read some posts from people what does words very gooder than what I does 😉

A slight return

Wait, what? An actual post written by me, and not just an auto-post from the images which I have shared on twitter. Not a long one mind you, but hey, a return is a return, right?

Anyway, take three minutes and thirteen seconds to go and watch this video about Alex Zanardi.
