Re: A Saturday Afternoon With the X-Pro3 + Viltrox AF33mmF1.4

ijonas — Fri, 04 Feb 2022 11:48:12 -0000

Hey Take,

I read somewhere that the Viltrox 33 can cause scratches to appear on the lens release button of the XPRo3.

Is this true or likely?

Thanks for the great article.

Greets from Scotland,
Ijonas.

Re: Headless Websites: What's the big deal?

ijonas — Wed, 16 Jul 2014 17:41:18 -0000

What's the impact on SEO and how would search engines parse a headless website.

I 'get" headless when we're talking about single-page apps but as a general purpose brochure site I don't see how 'headless' would work.

Re: Remove Metallica from Glastonbury line up

Not in the spirit of Glastonbury? But consuming a truckload of drugs and supporting a global drug trade is....

I'm not judging people using drugs, this just smacks of pious hypocrisy.

Re: Building a MongoDB Cluster using Docker Containers

ijonas — Tue, 29 Oct 2013 18:11:13 -0000

Hey Andre,

Also could you ensure that the mongodb.conf file is in

/mongodb1/data
and not
/mongodb1

I made a similar mistake on my environment and the got a similar error message to you.

Re: Building a MongoDB Cluster using Docker Containers

ijonas — Tue, 29 Oct 2013 18:03:47 -0000

Hey Andre,

Thanks for commenting. There's a couple of things you can try to find out what's going wrong inside the container.

First, run the container without -d param, instead use: docker run -i -t -v /mongodb1/data:/data andredublin/mongocluster

That will run mongod in the foreground and you should see console output.

If that fails you could try running with: docker run -i -t -entrypoint="/bin/bash" -v /mongodb1/data:/data andredublin/mongocluster

Doing so will override the executable that is run when the container boots. Having done so allows you to run [mongod -f /data/mongodb.conf] manually and observe its behaviour.

Things to check - and this may be stating the obvious - apologies. Does the folder structure /mongodb1/data exist in the host environment ? Does /data exist inside the container?

Also if you're trying to run the container in non-clustered mode, then you need to remove or comment out the replSet line in mongodb.conf

I'm going to try and follow my own instructions again, and report back.

Re: Building a Docker-based MySQL Server

ijonas — Wed, 16 Oct 2013 19:00:31 -0000

Great question, and I don't know a cast-iron answer. It depends on the contents of the container.

The Dockerfiles are the build-instructions for the image, and should exclude runtime configuration of the container.

At build-time the image shouldn't have any idea about whether its going to be used in a single instance service, or in a 3-node, or 9-node cluster.

You could for example have different images, one for 2Gb RAM MySQL Server, one for 8Gb RAM MySQL Server, etc... and in a non-clustered environment that would suffice. As soon as you need to combine two containers using each others runtime config (read IP-addresses) the idea of including DB config into the Dockerfile begins to fall apart.

Thanks for the feedback btw!

Re: Frames of reference for a startup community

ijonas — Tue, 23 Oct 2012 10:40:29 -0000

Not sure I understand your comment about a small business being dependent on a local community and is therefore constrained.

If a small Scottish business has a large, say US-based market then how is it locally dependent or constrained?

Building a sustainable business is hardly traditional. Its the hard part. Doesn't mean its boring, doesn't mean it lacks aspiration. Doesn't mean you can't exit for £40-100million pounds in 5yrs time.

Silicon Valley didn't end up with 250,000 tech jobs overnight. It developed track record.

I'm a hardened iOS fanboy, having used a Nexus S for a year and hating it, I can say the only feature a miss is no. 4 "Ability to Choose your default apps for Web browsing, email and more".

All the other points are mute.

Re: Frames of reference for a startup community

ijonas — Sun, 21 Oct 2012 08:34:42 -0000

One of the problems with any startup and venture capitalist community and tech media scene is the the focus on "100m users/eyeballs/consumers" and the desire to change the world.

Try building a sustainable business that lasts, employs people, pays off mortgages and helps collectively drive an economy forward.

Building a community around sustainable businesses helps attract talent allowing further startups to develop.

Remember, Silicon Valley has been around since the 1970s

For a lot of the grants you need revenues, because they only fund up to 50% of costs anyway.

We had a very good session with Scottish Development International, in which we mapped out a whole years worth of go-to-market activity, and one of the comments made was: "great that you guys have revenues, because you can actually afford to execute this plan and we'll help you"

Re: The Emberist: Absolute Paths in Classes

What would the guideline be on absolute paths to controller instances. Say in your example above you had a logout button next to current user in the user template.

Would you specify:

Re: Product Focused vs. Customer Focused Product Management: What’s the difference?

ijonas — Tue, 13 Sep 2011 06:07:38 -0000

I think the Lean Startup aspects that are wholly customer focused are those that concern themselves with building a business, i.e going from startup to bonafide business with gravy-train/revenue stream (pivot, pivot, pivot).

The pure product management aspects of Lean Startup are IMO product-focused with a healthy dose of customer-focus.

What defines each approach is entry point into the process. Both approaches need to end up answering the bulk of the same questions.

Re: Product Focused vs. Customer Focused Product Management: What’s the difference?

ijonas — Tue, 13 Sep 2011 05:29:43 -0000

Product focus commences with having the idea, gut instinct, self-belief, arrogance, whatever... and then moves backwards towards market validation, development effort/cost, go-to-market costs. Dominant question: how good/useful/fast/etc. is the product?

Customer focus commences with customer/competitor market analysis. Looking for unexploited niches and then through similar development/go-to-market costings as product-focus approaches, decides on what products will be most profitable. Dominant question: how big is the market?

My bias is product focused, as I think there's too much wasted analysis in customer focused approaches. Most market analysis tells you there's lots of potential customers and numerous successful competitors or early-entrants - i.e. its too crowded.

IMO approaches like Lean Startup, although they portray a customer-focus or being customer-led, are actually product focused. From a product management perspective Lean Startup helps a product-focused approach without betting the farm by weaving a customer-focussed elements early into the process.

Re: Why yo momma won’t use Google+ (and why that thrills me to no end)

ijonas — Fri, 01 Jul 2011 04:15:56 -0000

Its early days. I think there are two things Google can leverage to make G+ a more interesting proposition than Facebook for moms & pops.

1.) GMail. Lots of GMail users, so start weaving content from G+ into GMail sidebars to draw in the hordes.

2.) Chrome Marketplace and Android Marketplace app collaboration around Circles.

Re: Installing MongoDB 1.8.1 on Ubuntu 10.10 & 11.04 and running with an ‘init’ script.

ijonas — Fri, 20 May 2011 14:26:13 -0000

Thanks everyone pointing out the Ubuntu package route. I wasn't aware they had been updated.

Certainly helpful

Still... I think the configuration I outline above has merit as it allows you to quickly swap between new and old versions of MongoDB by flipping a symbolic link.
