Tapping Big Data to Your Own Advantage

See the original posting on DZone Python

Big data is the unfettered growth of an organization’s data, both organized and otherwise, in an unmanageable manner. This data, when managed well, can provide valuable insights to an organization, irrespective of the field it specializes in.Here, we present Cary, North Carolina-based SAS Institute’s, also referred to as SAS, take on big data. A developer of analytics software, the company…

Reflections on How the Devices We Have Can Affect What We Do or Think

Upon realizing that if I could do something on a PC in seconds but it takes lots longer on a phone and that’s all I have with me I often just don’t bother doing it at all.

5 things then:

Undefining “Technical Debt”

See the original posting on DZone Python

For me, technical debt is defined pretty loosely as stuff you don’t like in the code and need to change to keep up velocity. However, I’ve seen lots of articles lately discussing a precise definition of “technical debt.” I would sum them up as:

Like to make a game, but held up somewhat by the practical issue of having absolutely no artistic ability whatsoever? Yep, we feel your pain. Quite thoroughly indeed. But here’s a series of videos to watch that might help you fake it enough to get by –

How the JavaScript Heatmap Implementation Works

See the original posting on DZone Python

A heatmap is a powerful way to visualize data. Given a matrix of data each value is represented by a color. The implementation of the heatmap algorithm is expensive in computation terms: for each grid’s pixel you need to compute its color from a set of known values. As you could imagine, it is not feasible to implement it on the client side because map rendering would be really…

Geek Reading January 16, 2015

See the original posting on DZone Python

Today we have some cool news from MIT where they figured out how to watch immune cells communicate. Also from MIT, researchers used evolutionary algorithms to determine how to plan a wind farm with 1000 turbines, a highly complex problem with a cool solution. And finally, Flowing Data shows another fine example of people abusing charts and statistics, a fascinating read as usual.

As always,…

The Four Species of Agile

See the original posting on DZone Python

I’ve been a professional software developer since 2002 and worked for several software companies over the years – some practiced SCRUM, some used Kanban, some had a tailored made methodology and some didn’t have any methodology in place.

When starting with Agile a few years ago I found out that

“All waterfall companies are alike; each agile company is agile in its own way.”

Dumb and Dumber Is Better than The Next Big Thing

See the original posting on DZone Python

The software world is a strange beast. It is the only industry that has one million solutions and no paying customer problems. The other industries are the other way around. There is a tendency to open source and commoditise more and more solutions. The reason is that companies always migrate upwards in the value chain, meaning that the hardware, the operating system, etc. are now commodity…

Team Competition is Not Friendly

See the original posting on DZone Python

I once worked in an organization where the senior managers thought they should motivate us, the team members. They decided to have a team competition, complete with prizes.

I was working on a difficult software problem with a colleague on another team. We both needed to jointly design our pieces of the product to make the entire product work.

Why Programmers Should Have a Blog

See the original posting on DZone Python

Recently a few people were asking me why I have a blog. Some of them were not programmers. It reminded me about a draft of this post, which I have had for more than a year now. I planned to extend it, but I think keeping it short, and maybe edit in the future would be a better solution.

Here are the reasons why I have a blog:

If You Can’t Do It with Power, You Can Do It with MORE Power

IBM has released their Power8 CPU and with that a bunch of servers and also some other news around this, like the OpenPower consortium that has been around for a year or so now. Besides IBM, Tyan and Google have announced that they are building systems around the Power8 CPU, with the a Tyan server being on sale for some $2800, but this is not a server with a high-end configuration, but it is in a…
