Another Eve release is out and I’m particularly proud about it since it brings full Python 3.3 support (among other things). Check out the relevant blog post: Eve 0.0.9 is out!
I’ve got a problem. I am a perfectionist. I like perfect code. This is not only the correct way to develop applications but also the real proficiency. I enjoy reading a good listing not less than reading a good book. Developing architecture of a big project is no simpler than designing architecture of a big building. In case the work is good the result is no less beautiful. I am sometimes fascinated by how elegantly the patterns are entwine....
A really good comment is the one you managed to avoid. (c) Uncle Bob Lately, I’ve been feeling really tired of hot discussions on if it’s necessary to add comments in the code. As a rule, there are self-confident juniors with the indisputable statement as: “Why not to comment it, it will be unreadable without the comments!” on one side. And experienced seniors are on the other side. They understand that if it’s possible to go without the....

For those of you who are like me, trying to learn the Mac and Linux operating systems, Golang programming and deployment constructs all at the same time, I feel your pain. I have been building a Go application for a couple of months on my Mac and it was time to deploy the code on a local Ubuntu server. I was having a really tough time and it was turning into a disaster. Like always, I kept telling myself, I must be doing something wrong. ....
I’m going to build on Jamie Zawinski’s excellent advice about backups , which you should read first. This is basically that, but with some extra bits. If this seems too complex, then just do what he says . The plan is to use Backupninja to backup everything to an external USB drive – and also to Amazon S3 or Dropbox , depending on what it is. Backupninja provides a centralized way to configure and schedule many different backup u....
One of the issues I have run into running searchcode.com is that a huge amount of time spent serving pages is serving them to bots (about 900,000 hits a day are from bots). I have been watching the load averages and they can spike to over 30.00 occasionally which is pretty bad for a 4 core/ht system. I don’t have any problems with bot’s really other then the fact that I cannot really control them. Sure you can specify crawl delays but its o..
Hi All, So I’ve had a lot of feedback on the uservoice site, gripdev.uservoice.com, about the colour.

DevCon - engineering.cerner.com - 12 years ago - eng
This past June, 2,500 associates from across Cerner came together for DevCon, our internal developers conference. Now in its 3rd year, DevCon is a two-day, engineering-led conference that was created to bring together Cerner associates involved in all aspects of development and technology. DevCon is organized and run like many other developer conferences, complete with a call for papers and a talk selection committee. This year, we had 80 t..
If you are coming to Go after using a programming language like C# or Java, the first thing you will discover is that there are no traditional collection types like List and Dictionary. That really threw me off for months. I found a package called container/list and gravitated to using it for almost everything. Something in the back of my head kept nagging me. It didn’t make any sense that the language designers would not directly supp....
I love tabs, they’re so much easier to work with, but YAML doesn’t like them. I’m constantly adding them in accidentally, and puppet’s error message is a bit cryptic: Error: Could not retrieve catalog from remote server: Error 400 on SERVER: malformed format string - %S at /etc/puppet/manifests/foo.pp:18 on node bar.example.com This happens during a puppet run, which in my case loads up YAML files. The tricky part was that the error..

In an uncharacteristically long post from The Loop titled The state of Apple’s TV quest , Dave Mark made an interesting observation regarding Apple’s alleged impending entrance in to the television industry. The pertinent sentence — cited below — draws a parallel between the music industry prior to the introduction of iTunes and the television industry of today: Permalink.
On a recent episode of what I believe was Back to Work, Dan and Merlin mentioned in passing a great page on the MacRumors website offering buying advice for Apple products. Based on average product cycles and current rumors, the editors at MacRumors decide whether to give the green-light to purchasing a new Apple device, whether to caution against it in the case of a yellow light, or give a product the red light signifying their advice agai..
Possessing the ability to write a CMS and code a website is great — don’t get me wrong — but it’s neat little scripts like this one that make me glad I learned to program. Permalink.
Considering Huangshan’s extreme beauty, it’s not surprising that the area derives much of its significance from Chinese art and literature. It has inspired poets such as Li Bai, many Chinese ink paintings, and more recently, photography. According to Wikipedia, over 20,000 poems were written about the mountains between the Tang Dynasty (618-906) and the end of the Qing Dynasty (1614 to 1911). They’ve also inspired modern works, lending to t..
His paintings show a universe much like our own, but beside the everyday humans carrying out everyday activities are massive buildings and machines running on technologies currently unknown.” This is exactly the sort of article I subscribed to Visual News for. Very impressive. Permalink.
Warning: long-winded tech post. If you don’t want to improve your debugging skills or don’t have lots of free time, don’t read this. I decided to do some pro-bono debugging, and as I was diving in I thought that some of you might be interested in a glimpse of how I work. I find that […]
Yesterday I took part in Bellmanstafetten - a 5km relay race - with other runners from DICE. We had three teams, one of which was aiming to beat last year’s company record for the race (I wasn’t on that one). We got shirts and everything!
My previous post was about Oracle 12c SQL Scalar Subquery transformations . Actually I need to clarify its scope a bit: the previous post was about scalar subqueries inside a SELECT projection list only (meaning that for populating a field in the query resultset, a subquery gets executed once for each row returned back to the caller, instead of returning a “real” column value passed up from a child rowsource). I did not cover an other ....

During the 1950’s the famous mathematician Paul Erdős and Alfred Rényi put forth the concept of a random graph and in the subsequent years of study transformed the world of combinatorics. The random graph is the perfect example of a good mathematical definition: it’s simple, has surprisingly intricate structure, and yields many applications. In this post we’ll explore basic facts about random graphs, slowly detail a proof on their applicati..

I recently needed to convert some FLAC music files from the increasingly common 48 bit encoding, down to 16 bit at 44100 kHz, so that they’ll play on my Sonos. Here’s how to do it: If you don’t already have sox installed, do this to install it: $ sudo apt-get install sox Then run this to do the conversion, in the folder with music in: $ mkdir resampled $ for flac in * .flac ; do sox -S " ${ flac } ..
My son and I were having fun last weekend building a console based game in Go. I was recreating a game from my youth, back when I was programming on a Kaypro II. I loved this computer. I would write games in BASIC on it all day and night. Did I mention it was portable. The keyboard would strap in and you could carry it around. LOL. But I digress, back to my Go program. I figured out a way to use the VT100 escape ....
There’s a great movie to be made about the life of Steve Jobs, but Jobs is not it. The primary challenge in making a film about the co-founder of Apple is finding an actor who can play an overtly cerebral, egomaniacal dick, but a dick for whom you want to root. Besides a striking resemblance to the young Steve Jobs, Ashton Kutcher is a terrible choice: There’s nothing about his character that makes you want to root for him, and all of his a..
An Untenable Goal - zacs.site - 12 years ago - eng
Although the first movie adaptation of Christopher Paolini’s Eragon could have passed as a mildly successful yet unremarkable summer movie, it falls far short when compared to the original series from which it borrowed little besides character names and basic plotlines, only to discard the latter whenever the “director” deemed it convenient. Anyone who has ever seen a book-turned-movie undoubtedly read that without any surprise; the book ..
So, how many of you do hate the dialog below? Good news – there is a fix!

Machine learning is broadly split into two camps, statistical learning and non-statistical learning. The latter we’ve started to get a good picture of on this blog; we approached Perceptrons, decision trees, and neural networks from a non-statistical perspective. And generally “statistical” learning is just that, a perspective. Data is phrased in terms of independent and dependent variables, and statistical techniques are leveraged against ..

Midnattsloppet is a yearly night-time 10km race in Sweden, taking place in multiple cities including Stockholm. I’ve been signed up for months. It was yesterday. Let me tell you about it.
Note: this post was going to have pictures. Unfortunately my SD card is MIA. I’ll add them here when I can find it)
