2018 is an exciting time to be a programmer, with so many good “full service” programming languages to choose from: C, C++ 2017, Go, Python, Rust and who knows Swift too. Programming languages are complicated beasts - even the simplest languages have specifications that run (or would run) in the hundreds of pages,...

Welcome back! In part 4 we went over the nitty-gritty of lambdas and how to store them, we explored the relation between the various C++ algorithms and containers, plus we took a stroll through some non-standard containers with exceptional capabilities. Note: part 1 is here. In this probably final part 5, we’ll be...

Welcome back! In part 3 I discussed classes, polymorphism, references and templates, and finally built a source indexer out of basic containers that achieves 60MB/s indexing speed. In this part we continue with further C++ features that you can use to spice up your code ’line by line’, without immediately having to...

Welkom! Veel bedrijven en scholen in mijn omgeving worstelen op dit moment met het vinden van personeel. Sinds 1999 neem ik mensen aan en help ik bij werving, voor mijn eigen bedrijf & dat van anderen, maar ook voor scholen en instellingen. En als ik eerlijk ben, ik ben er inmiddels best goed in. In ieder geval ben...

Welcome back! In part 2 I discussed basic classes, threading, atomic operations, smart pointers, resource acquisition and (very briefly) namespaces. In this part we continue with further C++ features that you can use to spice up your code ’line by line’, without immediately having to use all 1400 pages of ‘The C++...

Welcome back! In part 1 I discussed how std::string and std::vector interoperate with C, including with the C standard library qsort call. We also discovered that the C++ std::sort is 40% faster than C qsort because C++ is able to inline the comparison function. In this part we continue with further C++ features...

Welcome to part 1 of Modern C++ for C Programmers, please see the introduction for the goals and context of this series. In this part we start with C++ features that you can use to spice up your code ’line by line’, without immediately having to use all 1400 pages of ‘The C++ Programming Language’. Various code...

Ahhh.. meetings. The one old school company thing that survives in this agile, open-office, ‘remote first’, nomadic worker world. And it is easy to see why: the ‘meeting’ is the last guaranteed way to get everyone to pay attention for an hour, or at least, pretend to. It still is rare for people to fake attending...

Comments are very welcome on bert@hubertnet.nl or @bert_hu_bert. Update: several constructive remarks have been used to improve this text. Thanks! In this post I will attempt to fully explain the Spectre and Meltdown vulnerabilities in an accessible way. I decided to write it up after I realised it took me more than...

Welcome to Kolmo There are three avenues to learn about Kolmo (GitHub). There are two Youtube videos, one from the most excellent NLNOG 2017, the other from the equally excellent UKNOF 38. These videos explain a lot of the the history and the ‘why’ behind Kolmo. There is also the kolmo.org website, which is...

Some brief notes on making ethernet cables With thanks to the most excellent NLNOG for a lot of mostly correct advice! Friends will tell you “crimping” ethernet cables is easy. Most of your friends either have overly rosy memories, or have practiced on 200 cables before telling you it is now easy. It is not easy....

Onlangs vond ik via LinkedIn een advertentie voor de vacature ‘Senior Category Manager Domestic Appliances’ bij bol.com. Hierin stond zoveel wartaal dat ik het de moeite vond een ‘best of’ selectie te delen op Facebook. Daar vond men het ook erg grappig. Desondanks is het de moeite waard de vacature te decoderen:...
