This is the world in the eyes of a dog The poor things have such a cold experience of the world. Our eyes while giving us a richer experience of the world are also a limited mechanical tool. The world doesn’t care though. It stays the same regardless of the tools we use to perceive it - whether it’s the eyes of a dog or my presbyc ones. This sounds like stoner talk, but hear me out.

In the technology world today, the term Open is most commonly associated with Open Source . Open Source refers to software released under a license that gives other software developers access to modify the original Source code that was used to create the software. This, in turn allows other software developers worldwide to quickly identify and fix bugs and security loopholes, as well as make feature improvements to the software. Co..

How playing the game Factorio reminds me of software engineering, from managing complexity to teamwork and automation

In this post we'll write a Python to C compiler in Python. This is especially easy to do since Python has a builtin parser library and because a number of CPython internals are exposed for extension writers . By the end of this post, in a few hundred lines of Python, we'll be able to compile and run the following program: $ cat tests / recursive_fib . py def fib ( n ): if n == 0 or n == 1 : retu....

The August 4th explosions in Beirut were very jarring to me due to the loss of human life, and the numerous , direct videos that looked like something out my 80s youth nightmares. Hearing that it was caused by 2,750 tonnes of ammonium nitrate , I started working on my phone to quantify my fear by figuring out how easy it would be to ship that much, and how much it would cost. According to wikipedia, there were at least 171 deaths;....

Not long after I found an old piece on attribution from Thinkst Applied Research , Cisco’s Talos Intelligence group posted an article on the same topic . Attribution is fraught, as both pieces explain. IP geolocation is woefully inaccurate, many of the tactics, techniques, and procedures tied to specific actors are either so common that they apply to several groups or so general that they might as well, and the proliferation of viable too..

Do you want to distribute your Python applications to other users who don't have or even use Python? Maybe you're interested in seeing your Python application run on iOS or Android mobile devices. This week on the show we have Russell Keith-Magee, the founder and maintainer of the BeeWare project. Russell talks about Briefcase, a tool that converts a Python application into native installers on macOS, Windows, Linux, and mobile devices.

If you’re like me, most of the mail you get anymore is junk mail. One common type of junk mail is “scratch-off promotions” from car dealerships. You know, those lottery-looking pieces that seem to award everyone the top prize?

Note : Updated on 2022-06-04 to reflect experience with actually maintaining these gems. This blog post talks about my experiences converting a handful of Ruby class libraries to gems. As do a lot of software engineers, I have a series of routines that I bring into almost every Ruby project I tackle that deal with what I consider core stuff you always need: url handling, database stuff, time parsing and so on.

mdfind is an OSX executable which taps into the underlying spotlight index to find files quickly. However if you want to quickly sort results you need to pipe its output (the symbol i.e. shift key + forward slash) into another program. The program we are going to send its results to is xargs which then handles integrating the results from mdfind with another command and organizing the results. Note : I regard xargs as "Unix Dark Mag..

Like a lot of engineers, I have a handful of personal projects I keep around for various reasons. Some are useful and some are just for fun, but none of them get the same sort of investment as a funded commercial effort. The consequence of this is that it's all the more important to keep things as simple as possible, to focus the investment where it counts. Part of the way I achieve that is that I've spent some initial time putting together....

Conventionally, robust competitive analysis identifies current and potential competitors, reflects on their strengths and weaknesses subsequently highlighting trends and uncovering opportunities. A popular framework to summarize the results of such an investigation is the fairly common Competitor Analysis Matrix (Fig 1). The matrix is a bird’s eye view of competition with an in-depth analysis of their offering.

One form or another of Two Factor Authentication - 2FA - (sometimes called Two step verification - 2SV) is becoming increasingly common. In particular, Time-based One Time Password (TOTP) is very widely used. TOTP is implemented in products like Google Authenticator , Microsoft Authenticator and Authy (amongst others). You absolutely should use an app like this for your day-to-day needs. However, sometimes it's useful to have a C..

Sometimes you want a BASH script to be able to fork itself, so that it continues to run in the background, so that it keeps running even if (say) the SSH session is disconnected. Although you could trigger it manually when calling your script, sometimes you want it to be conditional - if a lock exists you may not want to fork The mechanism this snippet uses is fairly simple, it checks to see if an environment variable is set, if not, it..
