Off topic but what tool did you use to create those cache hierarchy diagrams?


Right! Section 1.3 of this publication discusses possible mitigations for the row hammer problem and where ECC fits in

https://users.ece.cmu.edu/~omutlu/pub/rowhammer-summary.pdf


The paper you cite is from 2014 and the mitigations discussed there have all been circumvented. [1] is from 2020 and a better read for Rowhammer mitigation.

[1] J. S. Kim et al, Revisiting RowHammer: An Experimental Analysis of Modern DRAM Devices and Mitigation Techniques https://arxiv.org/abs/2005.13121


Thanks for pointing that out!


Good point on the need for awareness!

The industry has convinced the average user of consumer hardware that PPA (Power,Performance,Area) is all that needs to get better with generational improvements. Hoping that the concerning aspects of security and reliability that have come to light in the recent past changes this.

I thought ASML manufacturing was in Connecticut, USA? I heard this from Ian Cutress on his channel https://youtu.be/JyocuFlQmTc


I see you didn't mention Markdown. My solution for the last couple of years to this problem is to have all my notes organized into folder and .md files. A couple of advantages: - I can move around different IDEs/apps since there are a lot of different solutions for every platform there. - Same goes for search and links between folders. Rely on git for version control of the files themselves. - It gives you the flexibility of using plugins to turn into PDF or host as a gitbook private site for example.

Knowledge base organization gets discussed frequently on HN. I understand your frustration though, I've always longed to see a one fit for all platforms though. Onenote sure shows a lot of potential but is probably limited by the fact that MS wants to keep it as close to their office suite as possible.


Making a commit and pushing every time I edit a note would drive me nuts. I've gotten used to notes auto-saving and syncing. Additionally, reading md on android would require a specialized app anyway.


Same, I've settled with a multi-OS IDE for taking notes. The main issue is trying to get shortcut keys for Markdown such as toggling a list. I haven't found a good extension either on JetBrains or VSCode ... maybe the only way is to personally write the extension haha


Do you know an example of this?


Here's one I found on the Actions marketplace.

Humans have persistence. I guess that'll help them eventually get through using brute force.


Another thing to note is that sparsity is being leveraged even to build a more efficient version of hardware. A good example of this is the Cerebras Waferscale chip that was announced recently. I'm assuming the author was unaware of developments on the hardware side of things.


I did not find this mentioned anywhere but Onenote makes snips text searchable too


Evernote had it even earlier. The founder, Stepan Pachikov, has been working on OCR as far back as the '80s.


Evernote works surprisingly well. I'm always surprised when I search for something and it finds random photos of white boards that contain the word or phrase I'm looking for.

Good Notes on the iPad is also shockingly good at OCR for handwriting. At least for the way I write.
