The reality is that AngularJS is winning the frontend framework war. It’s not to say there aren’t great, high quality alternatives out there, but few have gained so much developer mindshare that slow and conservative companies see it as a wonderful investment. And it’s all the better that normal developers actually love developing with it! via Why AngularJS Will Be Huge .

A few days ago my girlfriend told me about the “lunk alarm”, a gimmick Planet Fitness uses to make its facilities more attractive to those who rarely go to the gym. Marketed as a judgment-free workout zone, Planet Fitness sets this alarm off whenever a patron makes too much noise during their workout; upon repeat transgressions, the gym’s managers will ask these people to leave in order to foster a less intimidating atmosphere — or so the r..

Why is storing, tracking and managing billions of tiny files directly on a file system a nightmare?

Its a real pain when you want to inspect the files, delete or copy them. Try taking 300,000 files and copy them somewhere. Then copy 1 file which has the size of the 300,000 combined. The single file is MUCH faster (its also why we usually do a tar operation before copying stuff if its already compressed). Any database that’s not a toy will usually lay the 300,000 records out in a single file (depending on settings, sizes and filesystem l..

The idea of Full-Stack Development is quite popular at the moment — building things that run both the browser and the server side of web development, usually utilizing similar languages and frameworks. With Flow-Based Programming and the emerging Flowhub ecosystem, we can take this even further. Thanks to the FBP network protocol we can build and monitor graphs spanning multiple devices and flow-based environments. Jon Nordby ga....

When I sat down to write this yesterday afternoon, two of the top five articles on Hacker News were not actually articles at all: the first pointed to a Microsoft page extolling the virtues of their new CEO Satya Nadella, below which the fifth “story” linked to Firefox 27’s release notes. In no universe would any person categorize either of these pages as something that “gratifies one’s intellectual curiosity.” In fact, I would say we can l..

The following is taken from my response to a Hacker News comment. The comment follows (quoted) and my response below. “I will start doing TDD when, 1. It is faster than developing without it. 2. It doesn’t result in a ton of brittle tests that can’t survive an upgrade or massive change in the API that is already enough trouble to manage on the implementation-side- even though there may be no functional changes!

You just learned how to create a simple WordPress plugin, and now you hear people talking about how WordPress is becoming more object-oriented. What does that mean? Lets take a step back and start with the basics. Most simple WordPress plugins are written using procedural programming. This means that your code excited from top to bottom; calling functions and setting variables along the way. A prime example of this is the default WordPres..

3/11/04 – 5/11/04 Let me recap the conversation I had with Tiff on the 5th over the phone. “Hello?” “Tiff Sorry about waking you. Have a look out the window” “Ok if I have to… OH MY GOD!!! SNOW!!!! I NEED TO CALL MY MUM!” Yes that’s correct. On the 5th I awoke to a winter wonderland outside. Not much snow apparently but it was enough to get Tiff and I excited. We had a snowball fight in the trees outside her and Susan’s room before clas....

I completely agree with Sid here: the growth of the internet as a widely-accepted medium through which to publish one’s thoughts and opinions as was once handled exclusively through corporate newspaporial publications with batteries of editors at their disposal has led to a net decline in literary quality over the last few years. The popularity of the link blog certainly did not help, perhaps it even compounded the already steady march, but..

The broad range of topics he covers makes for very interesting reading and highli..

The bracket expression [ ] defines single characters to match, however you can have more then 1 character inside which al..

Just last week the Kentucky Senate passed a bill by which computer programming classes would count towards a student’s foreign language requirement in high school. Although at first I wanted to see this as a boon for teenagers who would now have the ability to enter college or the workforce better technologically prepared, just as the bill’s proponents and Jim Dalrymple, who originally linked to this piece do, I’m not entirely sure this i..

Around minute 44:33 of Cube’s latest episode, Ben Bajarin theorized that Google’s motivation in selling Motorola to Lenovo while Samsung simultaneously agreed to scale back their customization of Android could have come about as a result of Samsung desiring access to a concrete feature road map which they could build to in the future. In my last article, Retroactively Planning , I talked about how Samsung’s backwards strategy in which ra..

Upon reaching a goal you cannot look back on the journey in search of the process that led you to success; you will invariably romanticize the past, shedding mediocre choices in a complimentary light, discounting difficult challenges, and misremembering strokes of genius in situations where there was none. In short, this exercise will ultimately only ensure that you never replicate any form of that success again. Rather than flying by the s..

Everybody involved, volunteers and attendees, has been very welcoming, charming and..

I can’t say I left the .NET Framework altogether as our main app was developed with .NET and we still maintain it on daily basis. Whenever applicable however, all the recent stuff is being done outside the walled garden. The following Jonathan Oliver totally resonates with my experience. The .NET Framework was good. Really good. Until it wasn’t. Why did I leave .NET? In short, it constrained our ability to choose (which is a huge deal..

PostgreSQL is currently entering its final commit fest. While its still going, which means there could still be more great features to come, we can start to take a look at what you can expect from it now. This release seems to bring a lot of minor increments versus some bigger highlights of previous ones. At the same time there’s still a lot on the bubble that may or may not make it which could entirely change the shape of this one. For a ....

I’m using a Lenovo X201 with 8GiB of RAM. Apart from some minor issues, I’ve been very satisfied with this laptop. It’s over four years old, and so I decided to see what’s available on the horizon. I did not buy an X240 because of the following reasons: The X240 has only one slot for RAM and thus supports a maximum of 8GiB. I think it’s pretty ridiculous for any successor to the X230 to support less RAM. In and of itself this is..

It’s a very interesting comparison of programming languages features and well worth the read. Toby writes: In class-based object-oriented programming, when there are classes that appear to share some functionality, this is often a time when people will refactor them into two subcla..

After buying my first Mac a few months ago , I soon grew quite fond of it as the most powerful computer I have owned to date. It zips through every task I can think to throw at it, and I can spend an entire day working without needing an outlet. Even better, it takes up so little space and ads such insignificant weight to my backpack that I regularly reach behind me just to make sure I didn’t forget it somewhere. My 15" Retina MacBook Pr..

Several years ago, I was new to my specific group at work. I was working on a combination of image processing and a GUI for keeping track of specific objects in the camera’s view. I started on the GUI first, writing a server that received object locations and handed them off to the GUI which displayed them in a nifty way. I was using Qt and QML, which I have used in numerous personal projects, so I was pretty familiar and confident with wha..

Having emptied my Instapaper queue last night and early this morning, I went back to my old stomping ground, WordPress, in search of some interesting articles on topics outside of Apple and, possibly, technology as well. I try to do this ever so often, looking to break the Apple-centric trend so many link blogs invariably fall in to these days. Today, pursuant of that goal, I found this great piece by a high school English teacher on tangen..

Filled with some of the best advice I have ever read on the subject, I return to this article every few months, gleaning just a little bit more each time. When I look back on the years since I started following Shawn, this piece stands out in my mind as his best work. And so, given how ..
