As an iphone developer contractor, I’ve released some applications on the Apple Store for my customers but not on my own. Here is my 1st personal (30 hours) toy project: 7shape a 7 minutes workout training application, based on an [NYT blog](http://well.blogs.nytimes.com/2013/05/09/the- scientific-7-minute-workout/) post. I’ve spent 20 hours on website release, marketing, 3D for the human trainer and application design, and last 10 hours to..

Recently I got together with some local developers to discuss client side MVC frameworks. We ended up discussing many of the differences between AngularJS and Ember . Discourse is an Ember application and has been since the first prototype, so I have a lot of experience with it. However, it became clear during the conversation with my peers that there was a lot about AngularJS I didn’t know. There is evidence that AngularJS is beat..

Figure 1. StackOverflow is made of people - lots and lots and lots of people. Seemingly like everything else in the world, Stack Overflow is getting more & more competitive as time passes. Gaining a good reputation - and even finding good questions to answer - is becoming harder and harder, as more and more people compete for less and less unanswered questions. This is fantastic if you want to find an answer - but makes it much harde....

Don't use string constants when writing SQL statements in code

I was always in two minds about using constants for table and column names when writing SELECT queries. Now I've concluded that constants are definitely bad, and should not be used. Here's why. The topic of discussion is difference is between writing sql = "SELECT * FROM " + TABLE_NAME + " WHERE ..." and sql = "SELECT * FROM my_table WHERE ..." There are the following consequences from this choice as far as I can see:

I’ve written a bit before about understanding the output from EXPLAIN and EXPLAIN ANALYZE in PostgreSQL. Though understandably getting a grasp on execution plans could probably use some more guidance. Yet, this time around I’m taking a bit of a cop out and highlighting a few tools instead of documenting myself, which I’ve done in a talk I’ve frequently given Postgres Demystified . Getting at the Data The first small thing you ....

When you look around you while sitting in a church service, you will generally have a sense of who is who. You know who the nice people are, who the grumps are and who always causes trouble. You know the people who always ask silly questions, and you know the people that always seem to know what to say when you are helpless. You might have an idea of who is a strong Christian and who has ways to go. We all do. What does the Bible say....

ReadWrite’s new site looks fantastic, very reminiscent of Digg’s current design. “It would have been easy at that point to rest on our laurels. But we and our colleagues at Say Media, our parent company, whose technology and design teams worked tirelessly on this launch, wanted to keep pushing our design forward and drop the remnants of the ’90s-era Web that clung to our site.” Good for them.

Reminds me of the old “I’m a Mac, and I’m a PC” days. Even though, as Ian Paul points out in his article, the commercial is laughably innacruate, I still had a good chuckle. Permalink.

I wanted to send an email from my TraceLog package when a critical exception occurred. Fortunately Go’s standard library has a package called smpt which can be found inside the net package. When you look at the documentation you are left wanting. I spent 20 minutes researching how to use this package. After fighting through the parameters and bugs, I came up with this sample code:

Apple has set fire to iOS. Everything’s in flux. Those with the least to lose have the most to gain, because this fall, hundreds of millions of people will start demanding apps for a platform with thousands of old, stale players and not many new, nimble alternatives. If you want to enter a category that’s crowded on iOS 6, and you’re one of the few that exclusively targets iOS 7, your app can look better, work better, and be faster and chea..

Almost every time Apple releases a new version of iOS, someone has the Marco Arment “Well, shit” moment . The time, most prominently, it was 1Password’s turn, although other small, one-off app developers likely had similar reactions throughout the keynote. Permalink.

The temptation certainly exists to criticize Satoru Iwata and his decision not to bring the company’s most popular titles to mobile gaming platforms like iOS; however, looking beyond our disappointment at being unable to play Pokemon and Mario Kart on the iPhone, we can look at the situation dispassionately and draw a number of parallels between Nintendo and Apple, Satoru Iwata and Steve Jobs: both men led (and lead) their respective corpor..

Wonderfully worded and impressively well thought-out, Matt Gemmel’s article iOS 7 is easily the best piece on the topic I have read since the WWDC keynote address. In explaining the motivation behind Apple’s complete UI overhaul in iOS7, he began his one-two punch with this paragraph: “The thing is, we’ve grown up. We don’t require hand-holding to tell us what to click or tap. Interactivity is a matter of invitation, and physical cues....

I try to, for the most part, stay positive when I write on here. Instead of taking a page out of Jim Dalrymple’s play book, not that there is anything wrong with his approach, and calling shenanigans and bullshit when I see shenanigans and bullshit, I try to “take the high road” and either ignore bad writing and poorly-formed opinions altogether, or criticize them generously. In the wake of the iOS 7 announcement though, many people have sa..

I think of it much in the same way I do exercise — you just have to make yourself miserable for a finite period of time, to reap the benefits later.” Another Soylent story, this one, interestingly, less lauding than the others. Permalink.

Over the last year, AdRoll’s mission of making retargeting easy and effective for everyone has really caught fire. Last month alone, we welcomed over 1,250 new advertisers to our platform. The secret to our success has always been layering the industry’s most intuitive tools over a powerful data backend to help companies collect, analyze and (most importantly) act on their customer data. Today, I’m excited to announce we’ve taken another ....

Surrounded by Tweetbot on my iPhone, iMore’s live blog on one iPad and Apple’s keynote stream on another, and flanked by my inconveniently inoperable computer, I watched Tim Cook introduce iOS 7. Even now, I can’t quite quantify the feeling I had upon seeing iOS 7 for the first time: a mixture of surprise and relief at the departure from almost every previously-held design philosophy, amazement for reasons that anyone who watched the keynot..

Although I make it a point not to spend much time talking about my personal life on this blog, it occasionally creeps in to my writing in the form of an anecdote, perhaps, or the inspiration for an entire article. A few weeks before Christmas last year, I linked to an article by Jason Snell titled Why I’m Writing on the iPad , in which he talked about a time when he was forced to write using a pen and paper rather than on a computer.

I have been struggling with using the Time package that comes in the Go standard library. My struggles have come from two pieces of functionality. First, trying to capture the number of milliseconds between two different time periods. Second, comparing that duration in milliseconds against a pre-defined time span. It sounds like a no brainier but like I said, I have been struggling. In the Time package there is a custom type called D..

There has been a lot of news recently on government surveillance of its citizens. The biggest two that have pervaded my news feeds are the protests in Turkey, which in particular have resulted in particular oppression of social media users, and the recent light on the US National Security Agency’s widespread “backdoor” in industry databases at Google, Verizon, Facebook, and others. It appears that the facts are in flux, as some companies ha..

This weekend I’ve been having a lot of fun working the Bioinformatics problems from Rosalind . Most people work them in Python, but so far they have been very amenable to Clojure except where BioPython libraries are used for access to online databases. The problems have been straightforward so far but I have enjoyed the elegance and brevity that Clojure lends the solutions. In particular, I like this short translator from RNA sequences....

Hi, So I’ve been working on a generic news reader to hopefully put the BBC News Mobile code base to a good use. Have a play and let me know what you think. It’s no where near finished yet so lots of room for tweaking, new features and changes. Let me know what you want via comments, @lawrencegripper on twitter or email phonesupport[at]grippers.co.uk and I’ll try and make it happen.

I am building my TraceLog package and it is really important that the package logs any internal exceptions and prevents panics from shutting down the application. The TraceLog package must never be responsible for shutting down an application. I also have internal go routines that must never terminate until the application is shut down gracefully. Understanding how to use Defer and Recover in your application can be a bit tricky at f....

How to switch to Compton for beautiful tear free compositing in XFCE

I switched my XFCE machines over to use Compton for window compositing today - and it’s a noticeable improvement. A compositor glues your stacks of windows together to form the final image that you see on screen. It’s responsible for any fancy effects like drop-shadows, as well drawing windows while dragging, resizing and minimizing or maximizing them. [1] Compton does this beautifully . It does one thing and it does it well. It pr....
