  • systeminformer

    A free, powerful, multi-purpose tool that helps you monitor system resources, debug software and detect malware. Brought to you by Winsider Seminars & Solutions, Inc. @ http://www.windows-internals.com

    Project mention: System Informer | /r/ITProTuesday | 2023-09-03

    System Informer is a versatile system management tool designed to seamlessly monitor and analyze system resources, troubleshoot software issues, and identify potential malware threats. Offers system activity overviews, intuitive graphs, real-time statistics, active network connection monitoring, detailed disk access information, intricate stack trace analysis, and much more. evily2k describes it "like process explorer on steroids. Allows me to kill process that task manager would say access denied."

  • pyroscope

    Continuous Profiling Platform. Debug performance issues down to a single line of code

    Project mention: Grafana Pyroscope v1.0.0 Release | news.ycombinator.com | 2023-08-29
  • WorkOS

    The modern API for authentication & user identity. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  • bytehound

    A memory profiler for Linux.

    Project mention: My Rust program (Well, game) is leaking memory, 4MB/s. | /r/rust | 2023-04-30

    I've found bytehound helpful for tracking memory leaks: https://github.com/koute/bytehound

  • dynamorio

    Dynamic Instrumentation Tool Platform

    Project mention: I feel like I'm stuck | /r/C_Programming | 2023-05-23

    You might ask what Job or what project. The answer depends on what you want to learn/do (as mentioned it codependent). If you want to know how the execution of a Programm happens in detail and how it can be manipulated during runtime you can dive into DynamoRIO (https://github.com/DynamoRIO/dynamorio). There, you can also learn a lot about instruction set architectures.

  • likwid

    Performance monitoring and benchmarking suite

    Project mention: How to implement the Substack's Casey Muratori "Instructions per Cycle" algorithm | /r/cpp | 2023-03-24

    If you want a portable library for reading performance counters that supports most processors out there, take a look at PAPI. Also likwid supports a huge number of processors and performance counters.

    Python frame stack sampler for CPython

    Project mention: Memray – A Memory Profiler for Python | news.ycombinator.com | 2024-02-10

    I collected a list of profilers (also memory profilers, also specifically for Python) here: https://github.com/albertz/wiki/blob/master/profiling.md

    Currently I actually need a Python memory profiler, because I want to figure out whether there is some memory leak in my application (PyTorch based training script), and where exactly (in this case, it's not a problem of GPU memory, but CPU memory).

    I tried Scalene (https://github.com/plasma-umass/scalene), which seems to be powerful, but somehow the output it gives me is not useful at all? It doesn't really give me a flamegraph, or a list of the top lines with memory allocations, but instead it gives me a listing of all source code lines, and prints some (very sparse) information on each line. So I need to search through that listing now by hand to find the spots? Maybe I just don't know how to use it properly.

    I tried Memray, but first ran into an issue (https://github.com/bloomberg/memray/issues/212), but after using some workaround, it worked now. I get a flamegraph out, but it doesn't really seem accurate? After a while, there don't seem to be any new memory allocations at all anymore, and I don't quite trust that this is correct.

    There is also Austin (https://github.com/P403n1x87/austin), which I also wanted to try (have not yet).

    Somehow this experience so far was very disappointing.

    (Side node, I debugged some very strange memory allocation behavior of Python before, where all local variables were kept around after an exception, even though I made sure there is no reference anymore to the exception object, to the traceback, etc, and I even called frame.clear() for all frames to really clear it. It turns out, frame.f_locals will create another copy of all the local variables, and the exception object and all the locals in the other frame still stay alive until you access frame.f_locals again. At that point, it will sync the f_locals again with the real (fast) locals, and then it can finally free everything. It was quite annoying to find the source of this problem and to find workarounds for it. https://github.com/python/cpython/issues/113939)
