Perf is probably the most widely used general purpose performance debugging tool on Linux. There are multiple contenders for the #2 spot, and, like perf, they’re sampling profilers. Sampling profilers are great. They tend to be easy-to-use and low-overhead compared to most alternatives. However, there are large classes of performance problems sampling profilers can’t debug effectively, and those problems are becoming more important.

Enter the URL of the website you want to test at low bandwidths, then select the bandwidth you want to simulate

Today, we are living in a connected world where information are accessed online but sometimes, it remains more convenient to have access to local information (stored on your computer). Having a local copy of the CVE database can be very helpful

A lightweight "signals and slots" implementation using fast delegates.

When GUI programming in C++, delegates and the signals and slots paradigm can vastly simplify your code. It implements the Observer pattern while avoiding all the boilerplate code.

Instructions to replace a live Debian installation with Arch

In-kernel ROP (Return Oriented Programming) is a useful technique that is often used to bypass restrictions associated with non-executable memory regions. For example, on default kernels1, it presents a practical approach for bypassing kernel and user address separation mitigations such as SMEP (Supervisor Mode Execution Protection) on recent Intel CPUs.

The goal of this tutorial is to demonstrate how a kernel ROP chain can be constructed to elevate user privileges

netboot.xyz is a way to select various operating system installers or utilities from one place within the BIOS without the need of having to go retrieve the media to run the tool. iPXE is used to provide a user friendly menu from within the BIOS that lets you easily choose the OS you want along with any specific types of versions or bootable flags.

You can remote attach the ISO to servers, set it up as a rescue option in Grub, or even set up your home network to boot to it by default so that it's always available

For decades, the C and C++ standards treated multi-threading and concurrency as something existing outside the standard sphere - in that "target-dependent" world of shades which the "abstract machine" targeted by the standards doesn't cover. The immediate, cold-blooded replies of "C++ doesn't know what a thread is" in mountains of mailing list and newsgroup questions dealing with parallelism will forever serve as a reminder of this past.
