Detailed Walkthrough Reveals X86 Execution Anomaly Investigation
[1/2] I felt like this question deserved a more complete answer than "undefined behavior", so I made a full walkthrough to show exactly what part of the x86 execution differs from the other two, and to demonstrate how you go about investigating an anomaly like this.
SemiAnalysis Invests $11M in Claude Tokens for Institutional Tool
SemiAnalysis spent $11 million on Claude tokens? I guess this is for making some kind of tool that is only available to their institutional customers, or something? https://t.co/4CrmI0wYZi
Unexpected Goblin References: Feature, Not Bug
Personally, I would consider "model often brings up goblins for no reason" a feature, not a bug.
Jimmy Wales Dismisses Source, Mirrors Wikipedia's Gaps
Perfect microcosm of Wikipedia: I tell Jimmy Wales that JangaFX was written in Odin. He asks for a source. A JangaFX founder replies to him and confirms that it was. Jimmy ignores his (and my) response, while replying to later...
Max‑setting Cyber
Well, not if someone in the single family home wants to play Cyberpunk 2077 at max settings - but I take your point. https://t.co/KTPoGJvvx5
Why AI Feels Different for Everyone, Even Same Tasks
Episode 3 of Wading Through AI is up! In this episode, @DemetriSpanos and I look at the aspects of AI technology that cause people to have wildly different experiences when using it, even for similar tasks: https://t.co/3GKLqTXCXL
Only Full Commitment Guarantees True Maxing
If you're not maxmaxxing, then anything else you maxx will not actually be maxed. Let that sink in.
IP Law Demands Payment; Ignoring Sparks Lawsuits
Actually Sam, we had something like that, except it specifically required you to pay the people whose economic viability you would be jeopardizing. We called it "IP law", and you decided you would rather ignore it and try to fight...
Live Deep Dive: Notch vs DLSS and GPU Hardware
I wanted to use Notch's criticism of DLSS to talk a little bit about GPU hardware, so I did an impromptu livestream last night. VOD is here if you're curious: https://t.co/rqlLnjNvmi
AI's Usefulness Evolves; Dismissals Must Adapt
Also, if you claim AI is useless, that is a claim about the current state of AI. If it subsequently improved to the point where it was clearly not useless (from your perspective), then if you are honest you have...
Superoptimizers Outperform Handwritten Assembly for Decades
Just for the record, superoptimizers that beat handwritten assembly are not new, and should not be considered an unexpected result. They are a very useful tool for finding optimal assembly on specific platforms. They have been in regular use by...
AVX‑512’s Extra Registers Eliminate FMA Spill Bottleneck
For a balanced architecture, it feels like there should be a rule of the form: 3*[fma latency]*[fma unit count] < [register name count] The 3 comes from the fact that you have up to 3 operands that feed each FMA. For example: on...
3Blue1Brown Visuals Echo Inigo Quile
@iquilezles For the entire duration of the latest 3blue1brown video, all I kept thinking was, "This is surely something Inigo Quilez had done in a shader at some point." https://t.co/wkzlP2lGY5
Industry Often Chooses Worse Practices Over Real Improvements
I've said this a few times now, but I'll keep saying it: it's also a mistake to assume that the industry in general cares whether something is a clear improvement. We have a long history of adopting new practices that...
Hand‑drawn Chip Designs Signal Elite Skill
While I understand what Jensen was trying to say, if a chip designer said they normally used pencil and paper to do their designs, I would probably assume they were baller AF, not the other way around.
