heaptrack VS jpegview

If we are talking replacing the libc allocator, then something like heaptrack is worth mentioning.

For accurate memory usage I prefer a memory profiler that overrides malloc and friends instead of the ones that probe the OS at regular intervals. You won't find memory spikes with the latter. Try heaptrack on Linux. I haven't found a good one for Windows yet.

I know it is not a profiler, but it is so criminally underrated that I decided to share it: https://github.com/KDE/heaptrack

If none of the above helps - I recommend heaptrack as a tool for tracking down your memory usage.

> memory leaks. It's surprisingly hard to find an easy to use memory leak detection tool.

I can vouch for heaptrack[1] nowadays, although it's pretty much Linux only. It's under the umbrella of KDE, but a heaptrack trace only requires a CLI app, and there is a nice Qt viewer to analyse the memory consumption.

It tracks the memory utilization at the level of malloc'd/free'd bytes. It's fine if your memory leak or other memory utilization problem is on this level. Recently I dealt with an issue, where increasing memory utilization was caused by fragmentation within the allocator. This didn't show up in heaptrack as an increasing memory utilization, but heaptrack still pointed out where most of the temporary allocations happened, leading to the culprit of the fragmentation.

When I had this kind problems (heap related) I always use heaptrack. Take a look here for the details: https://github.com/KDE/heaptrack

There is also JPEG View which is really fast and simple image viewer for windows https://github.com/sylikc/jpegview (fork of unmaintained https://sourceforge.net/projects/jpegview/)

It is very fast, specially noticeable on very large images

I've been using sylikc's fork of JPEGView for a few days. I like it, it's really fast, but it's too simple. I need something that is as fast, that is simple, but... just not too simple (I'd like the ability to draw on it). A better UI could be good too. Preferably open-source.

SumatraPDF, JPEGView [0], ShareX [1] are some great Windows open source softwares

Photo: JPEGview for image viewing, also modded Sumatra for pdf files and such

Recently started using jpegview https://github.com/sylikc/jpegview Was looking to customize some of the key mapping in the keymap.txt file

JPEGView: to open images from Windows Explorer. I use it as a default image viewer. It's Open-source, fast, lightweight, minimal, and clean UI. Arrows to move between images in a folder, Supr to delete, spacebar to full zoom. Download.
