What is a Golden File in software development?

Golden Files to run your test with large input and output dataWhile programming, one of the best thing to do to make sure that your software works as expected is to write tests.

Actually, if you write enough tests to make sure that the code works as expected, it should take you between two and three more time to finish up your project. So if it takes you one day to write a function, it will take you another two days to write good tests for that one function.

Many of those tests, especially as you construct more and more complex software, require large amount of input and output data. It's easy enough to test a function such as strlen(). It has one ...

What is the Significance of Tiny PCBs?

A PCB board with drawings of the wires

It’s a common refrain that our electronics are always getting smaller. While there may be some up-and-down fluctuation between one phone release and the next, the broader trend is clear: From speakers, to laptops, to home appliances, we can pack a lot more power into a lot less space these days.

This trend leads to some near-fantastical speculation about where tech can go from here. For instance, Quartz posted about limits in processing power back in 2017, and speculated that light could be built into processing chips as a substitute for what we’d now think ...

Don't Repeat Yourself When Writing Software

Nature tends to repeat itself, or reproduce with similar structure, but code should not.

For a very long time now, we have been using languages that support having functions that one can call. That was not always the case, although even really old versions of BASIC had a GOSUB instruction, which it had no concept of local variables so it was rather difficult to use safely.

Functions allow you to avoid repetition. You write a small snippet of code (or maybe not that small) within a function and then you call that function to reuse that snippet over and over again. Good programmers tend to do that even with one liners. However, many others often think: well, it's just one line, why don't I return copy & paste that wherever I need it, it's going to be faster.

How small are computers getting?

Mini-computer versus Mouse

Computer Stick

Looking at Mini Computers, I found this Fanless Mini PC based on the Intel Atom Z8350 processor by SmallRT. The picture includes a mouse to give you an idea of the size of that thing. It's tiny! Maybe not what you want, but you can already do a lot with that little one.

The connector on the left side is an HDMI plug which spits out 4K of video graphics. It's just totally amazing to me. Of course, we had the Pi3 and now we have the Pi4... but those are computers for hackers. Here we're ...

Safely Processing a Queue of Jobs

What is a Queue

In software a queue is a container which is used to add items on one side and remove them on the other in a very efficient manner.

Sorted Queues

When used by a Journal, a queue is often going to support some kind of sorted order. Some jobs are more important than others and these should be built sooner. In other words, we give those jobs a higher priority and we sort the queue by priority first then using the time at which the job gets inserted.

Note that the C++ std::queue and std::unque containers do not offer anyway to support a priority. Instead you have to use ...

Help with version 0.1.7 of Zipios (CVE-2019-13453)

Here is yet another example of why opensource is a really good way of getting things fixed.

Assuming you have a project that is getting used by many, you are likely to see people post issues about bugs and possible enhancements. Your software is even very likely to get improved on its own by enthousiast users. On Github, for example, it is very easy to fork a project (make a copy) and then work on your version of the software. You can then offer a fix to the main authors of the project with a near one to one copy of the project.

In our case, a security professional, Mike Salvatore, was asked ...
