Web frameworks are great, don't get me wrong here. They provide a structure and consistency across projects that will transcend developers over the life of a system while dramatically simplifying the code base amongst other wonderful side effects. But what's the downside?

As a comparatively new blogger I have done my fair share of self-promotion amongst the established writers I respect and strive to emulate, more than once recommending something I wrote by excusing my blatant plea for attention with the words, “I think you will like this” or some other permutation of the phrase. And each time I do I genuinely believe that John Siracusa might have found some interest in my argument for greater gesture suppor..

This piece from the New York Times touches on a subject that I’m passionate about - the challenges of hiring good people. Deep into it, it mentions that: “…the most proven method, Dr. Lewin said, is a referral from someone already working there. Current employees know the culture, he said, and have their reputations and their work environment on the line.” The big data thing is a cool, tech solution, but really it’s referrals that ..

Working with the Cloud Object API can sometimes be difficult. The data isn’t tabular and understanding the concepts such as indexes and scopes for such objects is pretty hard. To help alleviate this difficulty Chen built a tool right into the Codename One simulator that allows you to query the cloud storage for the current application and helps you review some of the complexities involved. You can query various application s..

I'm going to try using MathJax for displaying LaTeX maths in my blog posts. It seems to work pretty well. The only significant problem is the flash of unrendered latex code for 200ms or so when viewing a post. $$x = {-b \pm \sqrt{b^2-4ac} \over 2a}$$

The (Berkeley) sockets API should really have a function call to tell the implementation to do a local flush if possible, e.g. to stop buffering data and send the current packet. Let's say you are writing a webserver. Your webserver has received an HTTP request. You have read it in, decided on what page to return in response, and are now piecing the page together out of pieces of data and HTML. After each bit of HTML has been created y....

Try my flickr date fixer app ! So the startup/solopreneur community really likes little mantras and axioms. I wrote a little web application that follows mantras such as: solve a problem focus on a small problem in a niche market scratch your own itch build the minimum viable product and ship quickly I have built and released a web app that focuses on an itch I have and may serve a small niche market consisting of only myself, but wit....

I'm obsessed with performance tuning. It's an itch that can never fully be scratched. A sickness that can never be cured. Here's the story of how I caught the bug.

We have many interesting ways for you to make money using Codename One and pingjam is one of the most innovative ways we ran into. Pingjam ads are placed within the dialer window based on the number you are dialing to, e.g. you dial to purchase a pizza you might get an ad offering a discount for purchasing over the web!

A couple of weekends ago I had the great opportunity to attend lessconf . It was an all around great conference, and as a result of the greatness I ended up having a conversation with a few people around conference experience. I must give much of the credit to Swift , as he mentioned he’d already been thinking alot about this since Waza . In general it feels like there’s a few key themes that any conference should focus on, then a lot of....

I’ve been meaning to consolidate my personal websites onto this domain for a long, long time. My original personal website, dflock.co.uk , started in the late nineties - and has been getting a bit long in the tooth of late. Figure 1. Static text files - the gift that keeps on giving. That site has been up, looking mostly like that, for ~15 years - with zero maintenance or downtime. Nice to know it’s still valid CSS 1.0 :) When I c....

Today I tested the new plugin for nginx developed Google: ngx_pagespeed . It’s the equivalent for nginx to apache’s mod_pagespeed. Installation Just go to the github page for ngx_pagespeed and the follow the instructions there.I used the alpha-r2748-build. Sidenote: With it I ran into a problem with the wp-admin dashboard when trying to write this post. If you’re interested, check out the issue on Github. Test scenario For testi....

As I tweaked some last bits of code and added a few comments here and there, I realized I was getting excited. This project I had been working on for the last few days was almost done. I was happy about the code I had written and started prepping for a code review. My co-workers had been asking how it's going and wanted to give me feedback, so I pushed and deployed my changes to a staging server. What immediately followed was a humbling exp..

I feel almost guilty when I post non game or tech-related posts to this blog because I know the majority of people who come here tend to do so for the game/Impact/JS posts. However, this is a personal site and I do more than sit at a keyboard all day, so posts about running, Sweden, travel, etc are going to happen. Running and exercise is probably the category that’ll be popping up the most (after games) over the next few months as Stockhol..

Late last year, six women crowded in to a Mitte cafe booth and listened to Berlin Geekettes founder Jess Erickson share her idea: Berlin’s first all-women hackathon.

As I’m working with smaller and more agile projects, I’m increasingly seeing the classic way that Scrum is executed as more of an impediment to agility than a helper. This is especially the case when it comes to the classic Sprint Planning as described in [the Scrum Guide](http://www.scrum.org/Portals/0/Documents/Scrum Guides/Scrum_Guide.pdf): “For example, two-week Sprints have four-hour Sprint Planning Meetings” In the Sprint Planning Mee..

For a list of all the posts on Category Theory, see the Main Content page. It is time for us to formally define what a category is, to see a wealth of examples. In our next post we’ll see how the definitions laid out here translate to programming constructs. As we’ve said in our soft motivational post on categories, the point of category theory is to organize mathematical structures across various disciplines into a unified language.

Companies rarely promote people into leadership roles who haven’t been consistently seen and measured. It’s a familiarity thing, and it’s a trust thing. We’re not saying that the people who get promoted are stars during every “crucible” moment at the office, but at least they’re present and accounted for. And their presence says: Work is my top priority. I’m committed to this company. I want to lead. And I can. - Jack and Suzie Welch in a 2..

Is J2ME dead or dying? How many times have we heard this for the past 3 years or so? Sadly the answer is: Yes! Unfortunately there is no active owner for the J2ME standard and thus no new innovation around J2ME for quite some time (MIDP 2.0 came out in 2004, 3.0 never really materialized). Android is/was the biggest innovation since and became the unofficial successor to J2ME.

First configure php-fpm. [www] # The user nginx and php-fpm does run under. user = nginx group = nginx # listen on a sock-file instead o....

If any of you have been following me on Twitter over the weekend you may have seen my epic battle with node.js, MongoDB, socket.IO, Expess, and ImpactJS. It was like one of those jelly wrestling matches you see with drunk people fighting in kiddie pools, except instead it was me wearing pajama pants and a hoodie against a gang of five web technologies/libraries opening a can of whoop-ass on me.

We just added a new On/Off switch to Codename One that should allow you to use this component which is very popular on iOS (and gaining some popularity on Android), this is a rather elaborate component because of its very unique design on iOS but we were able to accommodate most of the small behaviors of the component into our version and it seamlessly adapts between the Android style and the iOS style.
