In a style made popular by Benedict Evans in his hallmark Twitter postulations, posit: computers were created for writers. As such, the next iteration of computing devices will cater to the needs of others: creators and designers will have Jarvis-like artificial intelligence systems to converse with and holographic interfaces to involve their entire bodies in the creation process. The current model involves the two tools of the writer’s tra..

Every so often an article crosses my path wherein the author drools over a custom shop’s awesome modifications to an already awesome vehicle, and then I invariably spend a good long while extricating myself from the inevitable rabbit hole that ensues. As of this writing, nearly four months have passed since I have gone down that path , continuing my trend of leaving roughly three months between each of these articles. Today, I’m back for..

Since starting this website nearly two years ago, I have written specifically about the engine that runs it exactly four times: in Introducing First Crack , I detailed my long journey to the realization that I needed to build something completely my own, from the ground up; later, I talked about some of my creation’s niceties in First Crack in Practice , before outlining the changes an innocuous redesign brought about in First Crack’s Co..

Introduction The concept of dependencies seems rather straight forward. If “Thing A” depends on “Thing B”, then we can understand that we can't possibly use “Thing A” until we have “Thing B”. It's not even a development principle really, it's more of an “even small kids realize this” kind of principle. It's sort of a universal given, unless you happen to be Gallifreyan. Taking that a step further, if you want me to make an application for y..

AdRoll’s customer dashboard is powered by our HBase cluster, populated using both Storm and Hadoop MapReduce . Using Storm allows us to provide real-time statistics to our users, while Hadoop gives us the accuracy guarantees needed for billing. Throughout the day, Storm emits a steady stream of writes to HBase. Our MapReduce jobs however, run once a day over the previous day’s data. This generates a huge spike in write traffic that can....

Very interesting take on the recent flare up around Disruption Theory, and how Lepore was not necessarily wrong to criticize Christenson and his theory, but that she did point to the wrong permutation of it: it is not necessarily the base theory that is flawed, but rather the watered-down version we find in use so often today. John Kirk then proceeded to delve further into the theory in a great follow up to Ben Thompson’s recent piece , C..

I have been carrying my Fitbit One for a little over two years with me and it keeps tracking my daily steps. It also tracks my distance covered by multiplying those steps using the stride length which you can either provide explicitly or implicitly setting your heights. In the winter of 2012 I bought my first ~Garmin Forerunner 410~ (replaced by a Garmin Forerunner 920XT) GPS watch to help me track my running (and other outdoor) activities.

I’ve been using Netezza for a few months now and this post captures my opinions based on my limited experience. For context, I’m populating a Netezza database for a client. The database schema is managed by the client, and Netezza was selected prior to my involvement. Netezza is their data warehouse, but they’re also using it a little like an application database. They’re using a bi-temporal model , but that’s a subject for another post.

In the process of growing a company there’s several hurdles based on the size of the company. What worked at 5 doesn’t work at 20, what works at 20 doesn’t work at 50, and what worked at 50 doesn’t work at 150. There’s a lot of talk about two pizza teams and scaling development teams out there. One thing I haven’t seen quite enough of is details around scribing and documenting things. Planning At teams of 2 and 3 you get everyon....

A while back I announced a preprint of a paper on coloring graphs with certain resilience properties. I’m pleased to announce that it’s been accepted to the Mathematical Foundations of Computer Science 2014, which is being held in Budapest this year. Since we first published the preprint we’ve actually proved some additional results about resilience, and so I’ll expand some of the details here. I think it makes for a nicer overall picture, ..

I linked to this piece by Ben Thompson in the title only because it is his most recent on the topic of disruption theory; I strongly encourage you to start with his earlier piece from last year titled “ What Clayton Christenson Got Wrong ”, where he more fully explains the theory and further expands upon some of its flaws. Especially if you — like me until now — only know of Disruption Theory in the abstract as explained in passing here and..

I am considering using a boilerplate for the introduction to this article, and keeping the actual noteworthy content the dynamic aspect going forward. So, let’s give it a try with last week’s opening: “Another week, another set of great podcasts for your listening pleasure. Enjoy.” Permalink.

Yes; fantastic piece from Sid O’Neill. I myself have begun to wonder the same things lately, questioning how I became so pedantic and obsessed with things of such little real importance that I would wax on endlessly about a simple ad , of all things. Yet, unlike Sid, I have been able to suppress those uncomfortable questions until very recently. As time marches on, however, and the amount of time I devote to this hobby only grows, this is ..

I once visited a team that had fifteen layers in their code. That is: If you wanted to display some data in the database in a web page, that data passed through 15 classes in the application. What did these layers do? Oh, nothing much. They just copied data from one object to the next. Or sometimes the “access object layer” would perform a check that objects were valid. Or perhaps the check would be done in the “boundary object layer”.

I never had a problem with the aesthetics of iOS 7, and continue to have no troubles whatsoever with it running atop my iPhone 4S: my phone never restarts, and my battery works just fine — especially for a device rapidly approaching its third birthday. Nevertheless, I can appreciate that many have had numerous and insurmountable problems in these areas as well as in many others, and that these issues have made iOS 7 a very difficult release....

When I moved back to the PHP version of Gastropoda I implemented snail death, so that snails actually die when their energy reaches 0. This resulted in all of my snails dying because they were both far below 0 (the cron job that depleted their energy daily continued to run while I was on a different branch).
