That sort of overflow can be avoided if the program includes sufficient bounds checking to flag or discard data when too much is sent to a memory buffer. Buffer overflows are among the most persistent and dangerousvulnerabilities in software, often exploited by attackers to gain unauthorized access...
Computer viruses can be a nightmare. Some can wipe out the information on a hard drive, tie up traffic on a computer network for hours, turn an innocent machine into a zombie and replicate and send themselves to other computers. If you've never had a machine fall victim to a com...
Oh, and a factoid (that drove me crazy in my early QoS endeavors, as I didn't initially know), Cisco interfaces often have a hardware FIFO queue, and it's only its overflow that can obtain its prioritized dequeuing by a QoS policy. (NB: what drove me crazy, ...
If you do not want to keep a slow loading add-on around, you can disable it, and it won’t be loaded the next time you open a new window or tab. You can also open Add/Remove Programs and remove IE add-ons that you are not using. This removes the add-on for all users on ...
How can this allocation for synchronous completions be avoided more generally in situations where the performance overhead really matters?That’s where ValueTask<TResult> comes into the picture (a much more detailed examination of ValueTask<TResult> is also available). ValueTask<TResult> started ...
First of all: Divide by zero is NOT a catchable C++ exception! That is a program bug and should be avoided (such as by sanitizing input with an if statement like Marcus demonstrated).If you need, for some reason, to catch Win32 exceptions, such as access violations and divide by zero ...
the buffer rests on the thing that causes input to be generated. If some user runs a command-line program he can cause to segfault by feeding a more than a certain amount of data into it, that's kind-of ugly and certainly not a sensible interface design for application ...
Of course, locks are still used internally when allocating or freeing from a region (since a malloc from one thread can still be freed in a different thread) but the chance of two threads contesting a lock is significantly reduced. The likelihood of cache lines shared unnecessarily between CPUs...
OpenGL not only allows you to draw to the screen, but also to textures (through a concept called a framebuffer). So we can encode the particle position as the RGBA color of the image, load it into the GPU, calculate the new position in the patch shader based on the wind speed, re-...
NGINX is a fast, light-weight and powerful web server that can also be used as a: fast HTTP reverse proxy reliable load balancer high performance caching server full-fledged web platform Generally it provides the core of complete web stacks and is designed to help build scalable web application...
