Damage is at the pad, so probably no. (the ESD protection structures that you're proposing to zap are not teeny tiny).

datameta · 6 days ago

Fair point about the protection structures lagging non-linearly in equivalent process node. Though wouldn't CDM events still correlate with feature density since the charge distribution across the die (assuming it correlates with the total gate capacitance)? More gates (higher density) means more to discharge safely?

Actually, for latchup specifically - even with oversized protection, don't the triggering conditions get worse with scaling since the parasitic SCR structures in the core have tighter spacing?

“Intel recommends an anti-static mat and a grounding wrist strap when installing a processor to avoid the danger of static electricity, also known as Electrostatic Discharge or ESD.1”

You know back when I built my computers, not once did I ever use any kind of static electricity discharge “system”. No wrist strap, no mat, no anything. And I don’t know anybody who did.

Has anybody ever actually destroyed a chip with static electricity?

(Of course it could be the climate I lived in as well)

The higher the feature density, the likelier a discharge of a given voltage will cause physical damage?

the murder rate in American cities is out of control. Maybe Americans are blind to this, but there are 274 murders in DC alone in 2023. In ALL of Germany, there were something like 600 murders in 2023. DC has 730,000 people living there. Germany has 83 million people. What do you mean that DC doesnt have a crisis going on? The homicide rate is 4,500% higher than Germany, lol.

I define "in control" as dropping for the last 30 years

Both things can be true at the same time, is not laughable at all.

Germany can be unsafe and US too to the extent they need national guard to get back control

datameta · 10 days ago

We don't need national guard in the capitol deployed. Completely fabricated claim that crime is out of control. Absolutely a move to gain power and create internal enemies to fight while a certain list of clients is being much discussed.

The term that comes to mind, and one of my favorite concepts, is "progressive disclosure", which is a concept we really ought to be more mindful of.

One of the perks of just-a-text-file-with-a-bunch-of-addons is that it enables progressive disclosure - it takes no learning curve to just get in and use the tool on a basic level, but additional complexity (and power) can be introduced over time.

The problem with a purpose-built app is that there's a minimum level of new concepts to learn before the tool is even minimally useful, and that's a barrier to adoption.

A good example of this in action is something like Markdown. It's just text and will show up fine without you learning anything, but as you pick up more syntax it builds on top - and if you learn some markup syntax but not others, it doesn't prevent you from using the subset you know. There is a clear path to adding new knowledge and ability.

Right, instead of fomo over not using the extra features of utilizing the right flow - people tend to experience the want/need to incrementally increase complexity when using roll-your-own software

Humor aside, there are people in the US who do get arrested for misdemeanors on purpose just to spend the night in a warm jail, and those that try to get into prison to alleviate chronic homelessness

Why is everything releasing today?

datameta · 19 days ago

Could it be nobody wanted to be first and overshadowed, nor the only one left out - and it cascaded after the first announcement? My first hunch, though, was that it had been agreed upon. Game theory I think tells us that releasing same day in the pattern ABC BCA CAB etc would be lowest risk and highest average gain?

I'm confused by how Opus is presented to be superior in nearly every way for coding purposes yet the general consensus and my own experience seem to be that Sonnet is much much better. Has anyone switched to entirely using Opus from Sonnet? Or maybe switching to Opus for certain things while using Sonnet for others?

datameta · 19 days ago

I now eagerly await Sonnet 4.1, only because of this release.

You're wrong about this. It's very clear, and some of the evidence is presented in the original article here.

I wouldn't like the takeaway from my comment to be that any extra intensity beyond daily walking is wasted. Instead my point is that for some, walking is one of the few exercises within reach that is sustainable with low injury risk.

I am also saying that for those new to the gym, starting with say 10-20 minutes every day is better in the long run than 1-1.5 hours three times a week before the body is acclimated or before proper form is developed. This lowers the risk of injury that could set back the health improvement endeavor.
