Lenovo Has a CXL Memory Monster with 128x 128GB DDR5 DIMMs (servethehome.com)
At OCP Summit 2024, we saw one more CXL monster, the Lenovo ThinkSystem SR860 V3. This system is listed on Lenovo’s website as having “Up to 16TB of TruDDR5 memory in 64x slots.” At the OCP Summit 2024, we saw this beast and how Lenovo is doing it with the help of CXL and Astera Labs Leo.

DIMM vs. Udimm vs. Rdimm vs. Sodimm vs. Cudimm: What's the Difference? (corsair.com)
It’s fair to say that there’s plenty of jargon around computer memory.
Stress can disrupt memory and lead to needless anxiety (nature.com)
Stress makes mice form big bundles of neurons in the brain that disrupt memory formation, making them fearful of harmless situations1 — which might help to explain why stressed people often feel threatened in safe environments.

'Brain stars' store our memories like a microscopic filing cabinet (newatlas.com)
Fascinating new findings into how clusters of 'brain stars' retain memories has changed what we know about how they're held in our minds.
The Difference Between a Standard DIMM and a Cudimm or Csodimm (servethehome.com)
We probably need to have one of these. Recently, memory makers started to take a technology that we have seen for years on the server side, and bring it to the desktop and mobile platforms. The CUDIMM or CSODIMM adds a “C” for clocked, and with it comes some new hardware.
Memories are not only in the brain, human cell study finds (medicalxpress.com)
It's common knowledge that our brains—and, specifically, our brain cells—store memories. But a team of scientists has discovered that cells from other parts of the body also perform a memory function, opening new pathways for understanding how memory works and creating the potential to enhance learning and to treat memory-related afflictions.

Storybits: Error Resistant Mnemonics (rya.nc)
At DEFCON 22, Dan Kaminsky and I talked a little bit about something I built which he dubbed “Storybits[1]”. Storybits can reversibly transform short strings of binary data into a series of words designed to produce a mental image.

Character amnesia in China (globalchinapulse.net)
During a visit to Beijing many years ago, I was having lunch with three PhD students in the Chinese Department at Peking University, all of whom were native speakers of Chinese. I happened to have a cold that day and was trying to write a brief note to a friend to cancel an appointment that afternoon. I found that I could not recall how to write the Chinese characters for the word ‘sneeze’.
Ask HN: Do you have trouble recalling what you've contributed at your job? (ycombinator.com)
I find that I really struggle to remember what I’ve done specifically before the current task I’m working on. Then I go through my tickets and I start remembering, but off the top of my head it’s pretty blank.<p>Makes me nervous about getting fired and having nothing to talk about in interviews. I should probably be writing things down as I do them.

When is causal broadcast not enough for causal memory? (decomposition.al)
While getting ready to teach my grad distributed systems course this fall, I found myself once again flipping through Cheriton and Skeen’s rather scathing 1993 article “Understanding the limitations of causally and totally ordered communication”.1 One of Cheriton and Skeen’s complaints about causally ordered communication is that it does not enforce the ordering constraints that they care about. They write:

Verbal Overshadowing (edge.org)
Suppose that two people witness a crime: one describes in words what they saw, while the other does not. When tested later on their memories of the event, the person who verbally described the incident will be worse at later remembering or recognizing what actually happened. This is verbal overshadowing.
