A precious memory In backwaters of the brain Is perhaps no wellspring but an island stranded deep.

ARM recently introduced a security feature called Memory Tagging Extension or MTE, which is designed to defend against common memory safety vulnerabilities, such as buffer overflow and use after free. In this paper, we examine three aspects of MTE. First, we survey how modern software systems, such as Glibc, Android, Chrome, Linux, and LLVM, use MTE. We identify some common weaknesses and propose improvements.…

If your program uses dynamic memory, its speed will depend on allocation time but also on memory access time. Here we investigate how memory access time depends on the memory layout of your data structure. We also investigate ways to speed up your program by laying out your data structure optimally.

A Brief Introduction   Prospective memory is remembering to perform delayed intentions at an appropriate time or event in the future. Examples of prospective memory include: remembering to tak…

Voters need to know who the candidates really are — not who they or their political teams want us to think they are.

Not a moment after I had walked out the door to catch a train to Berlin for the KDE e.V. board sprint (May 2023), there was a local power failure which took down my in-house IT. That wouldn't be so bad, except it did not come back up. Cue gnashing of teeth from the people who stayed at home (but, really, should have been able to hack into the router to fix it).

A visual introduction to memory allocation.

Construction of Intangible Memory (iozone) Intangible Memory, also known as the iozone, exists in an n-dimensional space. Moving between dimensions is ...

Japanese translator Michael Gurner, has just translated an intriguing short book which was a memory methods guide used in Japan, published in 1771. I was pointed to this by someone knowing how interested I am in these things, and contacted Michael yesterday because I found the book so interesting and want to find out more about memory methods as used in Asia. We are now in discussions about a number of aspects of…

Make ChatGPT unlearn the things it has learned about you.

In this blog, we will study the concepts of memory rank and organization, and how memory rank and organization affect the memory bandwidth performance by reviewing some benchmarking test results

If you've every asked 'what is RAM?', you've come to the right place

Hershey Felder's celebrated solo show Monsieur Chopin returns in an intimate production at Writers Theatre.

Redtwist's "earnest, intimate" revival of Agnes of God overcomes the sensationalist traps in the 1979 period piece.

Myra Greene's "Kept," the Atlanta artist's third solo exhibition at Patron, interrogates notions of archive and intervention with deft and delicate hands. The act of care drives Greene's mediation as the exhibition is composed from a collection of her grandmother's personal photos. Greene selected and reprinted specific images as ambrotypes in order to challenge assumptions […]

Working with fabric necessitates a certain type of intimacy. How you move through the world is punctuated by what you were wearing; fabric changes you, it can define your day. Fabric, whether it's worn or transformed, can thus become a complicated act of memory and storytelling.  "A thread through a past life," up at Middle […]

This article will focus on minimizing GPU memory footprint — for both optimization and inference workloads. Throughput and latency usually get all the attention, but reducing memory consumption without making architecture sacrifices is often just as valuable.
