Why is inlining so important in C++? Clearly, it reduces function call overhead: if a function is inlined, there is no need to spend time setting up its arguments, jumping to it, creating a stack frame, and then undoing all that upon returning. More interestingly, though, inlining enables other compiler optimizations. In this article, I will show examples of constant propagation and loop-invariant code motion (LICM). Then, I will explain how inlining enables these optimizations to apply more widely and show an example of the consequences when that doesn’t happen.
This post is about a few patterns I use when illustrating ideas about computers. If you are interested in using drawings to teach people about your very favorite computer topics, hopefully this will help you!
Let’s talk about how to structure cartoons and how to translate computer concepts into pictures!
Most graph theorists will agree that among the vast number of graphs that exist there are only a few that can be considered really interesting.
It is the aim of this House of Graphs project to find a workable definition of ‘interesting’ and provide a searchable database of graphs that conform to this definition. We also allow users to add additional graphs which they find interesting. In order to avoid abuse, only registered users can add new graphs.
Looks nice! I gave the
JPG -> PDF a try just now and it worked flawlessly. Going to play around with it a bit more!
Hello Gurlic world!
I’ve just launched a private-aware website for processing PDF documents last month, called PDF Shelter. It avoids communication with remote servers by performing all operations on the browser using open source JS libraries such as pdf-lib and pdf.js.
There are several new features in the pipeline, but I would like to show what we already have to gather some feedback on functionality, UX, etc. Thanks!
The kernel project goes out of its way to facilitate building with older toolchains. Building a kernel on a new system can be enough of a challenge as it is; being forced to install a custom toolchain first would not improve the situation. So the kernel developers try to keep it possible to build the kernel with the toolchains shipped by most distributors. There are costs to this policy though, including an inability to use newer compiler features. But, as was seen in a recent episode, building with old compilers can subject developers to old compiler bugs too.
Today, we’re launching our first microcontroller-class product: Raspberry Pi Pico. Priced at just $4, it is built on RP2040, a brand-new chip developed right here at Raspberry Pi. Whether you’re looking for a standalone board for deep-embedded development or a companion to your Raspberry Pi computer, or you’re taking your first steps with a microcontroller, this is the board for you.
It is an unfortunate fact of life that non-free firmware blobs are required to use some hardware, such as network devices (WiFi in particular), audio peripherals, and video cards. Beyond that, those blobs may even be required in order to install a Linux distribution, so an installation over the network may need to get non-free firmware directly from the installation media. That, as might be guessed, is a bit of a problem for distributions that are not willing to officially ship said firmware because of its non-free status, as a recent discussion in the Debian community shows.
We’ve seen that several companies have abandoned their original dedication to the open source community by switching their core products from an open source license, one approved by the Open Source Initiative, to a “fauxpen” source license. The hallmark of a fauxpen source license is that those who made the switch claim that their product continues to remain “open” under the new license, but the new license actually has taken away user rights.
