Schema vs Query-based Multitenancy

2014-11-23 at 23.17

Most SaaS application are “multi-tenancy” to some extent (i.e., host more than one customer on the same system) but typically the term is reserved for apps that have company accounts, each with multiple users, authorisations etc. These companies would like to believe that company.mywebapp.com is their instance of MyWebApp and that you’ve lovingly prepared and […]

When you hire them, their problems are your problems

2014-11-13 at 22.08

As a young corporal in the Air Training Corps, one of the most valuable lessons I learnt was: You can delegate responsibilty but you cannot delegate accountability What does that mean? It means that when you delegate a task to a subordinate, you give them the responsiblity and the authority to get it done. When […]

Can your entrepreneurial need be satisfied working for someone else?

IMG_8136

I was listening to a recent episode of the Fizzle show where they announced the departure of one of their team. Caleb was a founding member of Fizzle but is leaving to start his own business, and it prompted them to ask: Can you be satisfied, entrepreneurially, in a company, if you’re not in charge? […]

The Ruby in Rails

2014-10-20 at 17.04

Back in August I did a short talk at Corkdev about the features of Ruby that make Rails so easy to work with. The aim was to show off Rails to a general tech audience but without being all preachy about it. So instead I flew through the actual Rails stuff and then looked at […]

Generating a hierarchical graph with Rails & Javascript

2014-10-20 at 21.50

At WorkCompass, we can import a .csv file of employees from a customer but, as anyone who’s done anything with CSV files knows, you need a lot of validation to make sure the data is clean. Among the automated checks are some manual things like “these are the email domains used, are you sure they’re […]

We killed them and didn’t even notice

Dead Fox

We’ve killed 50% of the wildlife on this planet in the past 40 years. Does that disturb you? Probably not, I suspect. Most people will walk past a rustle in the bushes not realising that a Blackbird is foraging in there. They’ll drive past the flock of Starlings (whose population has declined 66% since 1970’s) […]

Is the Apple Watch ‘good’?

edition_red_leather_large

So Apple finally announced their watch and everyone can claim they predicted it. As a piece of design, it is pretty nice, much cheaper than I’d have expected and will be sure to gather a fervent following of fans. To be honest, I think the design is bulky and not something I’d like to see […]

Business is about happiness

Zen

There’s an attitude that business is about money. It’s not. Or, at least, it shouldn’t be. The thing that business does is to exchange goods and services for money; but at the core, it’s not about money, and it’s not driven by money. If it was about the money… If it was about money, you’d […]

How to Build a Raspberry Pi Camera Trap

05-20140814123021-01

I started with a low-tech footprint tunnel to get proof of our local hedgehogs but that was never going to be enough. I had a Raspberry Pi sitting in a drawer that wasn’t getting much love so, after a little googling a Raspberry Pi Camera Trap, aka a ‘PiTrap’, was born. The idea is to […]

Every company has two markets

IMG_7034

“Make something people want” includes making a company that people want to work for — Sahil Lavingia @gumroad I saw that quote in an article on the Inside Intercom blog and it really struck me as something that many founders fail to see until it’s too late — particularly non-technical founders. Your ‘other’ market When […]
