There are many different types of testing which exist in software engineering. They should not be confused with the test levels, unit testing, integration testing, component interface testing, and system testing. However the different test levels may be used by each type as a way of checking for software quality. The following are all different types of tests in software engineering. A/B A/B testing is testing the comparison of two ..

Snyk founder Guy Podjarny joins Courtney Nash on the new O’Reilly Security podcast, discussing key topics such as: - Why developers should own security, and why they haven’t done so yet - How can we bring the DevOps revolution into the world of security - What are each of our roles in improving Open Source Security - More tactically, handling vulnerabilities in open source components

Remark : I have not had this problem in years, and it’s probably long resolved. Unless you’re using Debian, where people care about this, chances are that setting up GPG Smartcards with your Linux distribution is an adventure. There are two ways to do it, CCID and PCSCLite, the latter of which runs a background service pcscd – as root, at least on Arch, while GnuPG’s built-in CCID driver accesses the reader directly through the USB dev....

I’m talking to myself but you can join the conversation. It goes like this… How much is your time worth? Ten dollars per hour? Fifty dollars per hour? Thousand dollars per hour? If you pick a number that you like, can you use it to justify your spending habits, to justify buying expensive clothes and car? How much is your time worth? When you wake up with a hangover, is your time worth as much as when you’ve slept well and drank a coff....

If you know me, or have read various sections of my website, you’ll know that I am a die hard member of the computing industry that also likes to collect vintage computers (this is actually quite common - you’d be surprised how many of my colleagues do the same). Yesterday, I managed to find a very interesting canvas painting in Toronto (the picture at the top of this post), and just HAD to have it. From the signature, it was painted ..

I built this subway style data visualization of Ludwig Wittgenstein’s Tractatus Logico-Philosophicus for Philosophy professor David Stern and graduate fellows Philip Ricks and Landon Elkind at the University of Iowa. They came to me with an Excel file sketch of an idea they had about a brand new way to read this seminal philosophical work. […]

Minimalist interpreters have always attracted me. First of all, they are a good fit for embedded systems whenever you need a custom domain-specific language. If one needs a scripting language for a microcontroller - there is not so many choices. Instead there are lots of constraints, like the size of the compiled binary code, RAM usage and memory management. Of course the language itself is important, too. Lua, a very stable, pragmatic and ..

A bit over two years ago I blogged about migrating to Octopress from Wordpress, this time I'll blog about migrating to Hugo from Octopress. I started messing around with Hugo because I was experimenting with Go and wanted to take a look at a simple and complete Go project. I ended up liking the simplicity of setting up a new site and decided to try porting my blog to it.

My work setup requires a non-administrator account for normal login. I have sudo access set up for my normal user. For some reason, Atom's autoupdate feature can't seem to deal with this and gets stuck in a loop trying to install updates. So I just scripted it as below: update_atom() { local atom="${HOME}Downloads/atom.zip" echo -n "downloading…" curl --silent --fail --location 'https://atom.io/download/mac' > "${atom}" echo "✓" local..

In the Visual Studio 2015 standard library, the implementation of std::map::find is unnecessarily slow. The underlying reason seems to be similar to that for bug #2 - using operations on a generic tree class that doesn't take advantage of the restrictions places on std::map - that entry keys are unique. The issue in detail: std::map::find() calls std::_Tree::lower_bound, which calls _Lbound, which looks like _Nodeptr _Lbound(const _Oth....

std::map and std::unordered_map performance bug #2 - slow count

How do you tell if an entry with a specific key has been inserted in a std::map and std::unordered_map? Historically the way was to call find and compare against end , e.g. if(m.find(x) != m.end()) // If present: // do something With the introduction of C++11, there is another technique - calling count . if(m.count(x) != 0) // If present: // do something Count returns the number of entries with the given key. Note also that....

An apparent performance bug with some std::map and std::unordered_map implementations

A few days ago my colleague Yves mentioned a perplexing finding to me - It was significantly faster to call find on a std::unordered_map, and then insert a item into the map only if the find call indicates it is not present, than to just attempt to insert an item directly with an insert call. This is strange, because the semantics of std::unordered_map::insert are that if an item with a matching key is already in the map, then the i....

Email might be one of the most often overlooked pieces of any web application. Usually the biggest discussion around it in a project begins and ends with “and we’ll send them an email when this happens…”. A little thought and some minor adjustments can help us avoid some problems that will grow as your project does. Let’s talk about email as a microservice.
