A recent tweet by a friend of mine noted how the public interest in the Scala programming language seems to have plateaued or waned, which matches my feeling of the latest trends and zeitgeist. This blog post will go into why I think that has happened, where Scala stands now, and what the future holds for the Scala community.

How browsers work Stay organized with collections Save and categorize content based on your preferences. Preface This comprehensive primer on the internal operations of WebKit and Gecko is the result of much research done by Israeli developer Tali Garsiel. Over a few years, she reviewed all the published data about browser internals and spent a lot of time reading web browser source code. She wrot
Realistic is not necessarily the most convincing. Audio designers know that well and use frozen leeks and watermelons to create sounds of breaking bones and tearing flesh. Chalk shot from slingshot was safer alternative for actual firearms in old westerns. Fake doesn’t have to mean worse, especially when it is hard to tell the difference. With that in mind I will try to create complex flowfields w
How a simple Linux kernel memory corruption bug can lead to complete system compromise
In this case, reallocating the object as one of those three types didn't seem to me like a nice way forward (although it should be possible to exploit this somehow with some effort, e.g. by using count.counter to corrupt the buf field of seq_file). Also, some systems might be using the slab_nomerge kernel command line flag, which disables this merging behavior. Another approach that I didn't look

This is a big milestone, and we know many users will be itching to try these out in their o
Today, we’d like to highlight a dangerous anti-pattern in the identity world: the false identifier anti-pattern. An anti-pattern is a common response to a recurring problem that’s usually ineffective and risks being highly counter-productive. You may have also heard of the password anti-pattern. Today's discussion represents a possibly even more dangerous practice. The false identifier anti-patte

Speed of Rust vs C
The run-time speed and memory usage of programs written in Rust should about the same as of programs written in C, but overall programming style of these languages is different enough that it's hard to generalize their speed. This is a summary of where they're the same, where C is faster, and where Rust is faster. Disclaimer: It's not meant to be an objective benchmark uncovering indisputable trut

So, What's So Special About The Mill Scala Build Tool? Mill is a Scala build tool that offers an alternative to the venerable SBT toolchain.

Feedback from users of Mill is often surprisingly positive, with people saying it is "intuitive" or feels "jus
In this blog, I am going to explain the important concepts of Heap and use the ptmalloc in the Glibc 2.31 library as an example. The heap is a beautiful mess :) I really like the saying shown above.

Grab your cup of tea and let's go. Dynamic import() ES2015 introduced the static import syntax. Now you coul
