Aditya Dwivedi recently did an interview with me about searchcode. You can view it here over on yourstory.com and it covers how the idea came about, some of the issues and where I think the future lies for the project. Going to include an extract below in case bit rot sets in. How this Aussie coder is making life easy for techies around the world with searchcode You are busy building your product and then someone comes and tells yo..

Quite some time ago, I started this draft with a simple premise: precluding success is failure of at least one effort in a given area. Put differently, those who have yet to fail in their chosen profession can never attain greatness in that field. Along with this supposition, I included one more stipulation as an addendum to the previous statement: one can, however, substitute knowledge, to a degree, for failure. Regardless of the knowledge..

When I was a young child, I remember listening to an old radio receiver with my grandfather, looking for morse transmission. 30 years later, I take the opportunity to get my radio amateur license in the US, it was not difficult (Technicial license is easy), especially cause US radio amateurs are using the metric system (almost all the time …), the only difficulties were to learn some terms and simple formulas from french to english and to k..

If you've spent any time looking at the items that I post, you've probably gathered that I'm a developer, but that I have a rather strange habit of not talking about code. I talk about build automation, source control, compiler output, virtualization, proxy servers, and continuous integration, but I barely talk about matters of code. So if I love coding, why do I spend my time talking talking about DevOps rather than code?

When Greedy Algorithms are Good Enough: Submodularity and the (1—1/e)-Approximation

Greedy algorithms are among the simplest and most intuitive algorithms known to humans. Their name essentially gives their description: do the thing that looks best right now, and repeat until nothing looks good anymore or you’re forced to stop. Some of the best situations in computer science are also when greedy algorithms are optimal or near-optimal. There is a beautiful theory of this situation, known as the theory of matroids. We haven’..

This situation really is crazy. Part of the problem, though, at least where Twitter is concerned, is that Twitter does not use the t.co shortener until after a tweet is posted, which means after it imposes the 140 character limit. Especially for me where every link to one of my own articles that I post starts with “zacjszewczyk.com/Structure”, this makes not using my own shortener — in this case, Bitly — completely impractical. Even then ..

Capture HTTP traffic with Fiddler on Devices with no Proxy option

Hi, This is how I ended up writing a custom DNS server to redirect network traffic.. code is here . I recently got a smart TV and I wanted to see what it was up too, having heard all the stories of them leaking personal information left right and center. Fiddler is my go to tool for any HTTP inspection, so I went about look for a proxy setting in on the TV … there isn’t one.

An overview of Ruby, jRuby, Rails, Torquebox, and PostgreSQL that was presented as a 3 hour class to other programmers at The Ironyard in Greenville, SC in July of 2013. The Rails specific sections are mostly code samples that were explained during the session so the real focus of the slides is Ruby, "the rails way" / workflow / differentiators and PostgreSQL.

The problem with Google Glass is not that it is inherently creepy, but rather that it has the potential for many uses of dubious morality; and as our minds happened upon those possibilities in the wake of Glass’ unveiling, and we paused to ponder an appropriate reaction to these eventualities, it became socially acceptable to walk around smacking these expensive devices off the faces of those who deigned to wear them. Like a small child who..

Working with web applications in NodeJS is great. Using the same language and libraries on the client and server simplified the thinking. And NodeJS has fast tests and restart for a super quick edit-verify cycle when you’re coding. I like to write tests to verify the server-side and client-side logic, but do you know that the whole solution really is working? You can of course test your service manually after deploying, but that becomes ted..

A friend of mine had a photovoltaic system (consisting of 14 solar panels) installed on his rooftop last year. As I was looking for another raspberry pi project I convinced him I would setup a reliable monitoring solution that will lead him to an access to the data in real-time data. The current setup comes with an inverter by the company Kostal. The Kostal Piko 5.5 runs an internal web server showing statistics like current power, daily en..

RDTSC doesn't actually measure the number of clock cycles elapsed

eng
The RDTSC instruction on x86 CPUs is supposed to read a counter that is incremented (by one) every clock cycle. However, it doesn't actually do this. Instead, the counter increases at a fixed frequency, independent of the actual clock speed of your CPU, which varies based on load, temperature etc.. This does not seem to be documented anywhere. I found this out the hard way, after measuring the frequency of rdtsc myself, and notic....

Since Apple began requiring that developers submitting applications to the Mac App Store sandbox their products, it has remained a somewhat controversial decision. Two years after the rule went in to effect, it continues to preclude a number of great apps from sharing in the spotlight Apple so generously — and to such great effect — sheds on its platform’s developers by featuring their creations on the store’s front page. Nevertheless, by a..

The drunken scribblings of a mad man. Possibly some kind of ancient cuneiform. A random page out of the Middle Earth phone directory. Whatever it was, it was the server password, not that it matters now: the little Post-It note reminder had long since thrown itself into the waste paper bin. Somewhere a landfill sat, knowing our password and chuckling away at our misfortune. It seems that our hero is in a bit of trouble, if only slightly sel..

At the end of March, some of our teams held their first 24-hour hackathon, titled ShipIt: Millennium+ Services FedEx Day. We had 41 participants, in 15 teams working on 15 unique projects. The idea was inspired by several teams spending a few hours every so often to work on different projects. After reading about Atlassian’s hack days, we decided to hold one. The event was initially announced early in February, to give teams time to work th..

Hat-tip to Hayes Brown for tweeting this link, apparently Amazon does, indeed, sell everything — including, it seems, radioactive uranium ore.

The other day, as I drove home from work and practiced my dictation to the tune of Siri’s inept transcription abilities, I deftly tapped iMessages’ “Send as Text Message” tooltip for what — given the number of text messages I send each month — must quite literally fall somewhere in the neighborhood of the millionth time. I tapped this button two or three times until, finally, my phone realized I wanted every outgoing message sent without th..
