Fronius and PVoutput

I've been playing around with PVoutput.org - it's a community site which lets you quickly and easily publish live details of your solar panels. I couldn't see a pre-built library for my model of Solar Power Inverter - the Fronius - so I thought I'd build one. Important: the PVoutput API doesn't run over HTTPS. All of your communications with it are in the clear. While there's a limit to the …

Two men are confused by a paper map

I don't understand how our Government works. I understand that tough decisions often need to be made - but sometimes those decisions are so utterly without reason that you have to wonder if politicians spend most of their days "painting their noses". The UK used to have a public sector postal service - the Royal Mail. Postmen need to know to where they were delivering mail. Postal Codes were…

My father tells a story of when I was very young and helping him do the shopping in the local supermarket.

Imagine all your fruit being touched by black people." At the time, South Africa was control by…

Earlier this year I was playing around with DogeCoin. Try as hard as I might, I just couldn't get their API working. I delved into the settings, to see what was up.

By carefully hovering my mouse over the options, I could see what I…

Private Eye - Not As Clever As They Think They Are

· 2 comments · 300 words · Viewed ~291 times


Private Eye is the only "Dead Tree" publication I buy. I think its satire misses the mark more often than not - but its investigative journalism and general muck-raking are second to none. The Eye has reluctantly been drawn into the digital age. It has a piss-poor website run by the sort of "tired and emotional" gnomes who struggle with concepts like sanitising user input. EXCLUSIVE Push…

WebDAV, SSL Handshake, OwnCloud, CloudFlare, and Ubuntu 12.04

Right, that's enough keyword stuffing! I've been trying to mount an OwnCloud instance via WebDAV. I kept receiving the error Mounting failed. SSL handshake failed: SSL error: sslv3 alert handshake failure Or SSL handshake failed: SSL alert received: Handshake failed The route of this problem seems to be that the version of libneon (the WebDAVS connector library) shipped with Ubuntu 12.04…
