When it works, it works great. But how about when it don't?

Passkey - what would happens when we lost the device? You need some kind of recovery, right?

Social recovery - of course you could do that. Are you doing one recovery for all accounts (which require some kind of "wallet" stored in a centralized location - and can be disabled)? Or one for each services (which may make your grinder account known to your family)?

How about tourists? When you lost your phone while you are traveling in other country, what should you do?

Any EEs that can comment on at what point do we just flip the architecture over so the GPU pcb is the motherboard and the cpu/memory lives on a PCIe slot? It seems like that would also have some power delivery advantages.

It is not a EE problem. It is an ecosystem problem. You need a whole catalog of compatible hardware for this.

As a parent of a young kid, empathy definitely needs to be trained with explicit instruction, at least in some kids.
j16sdiz · 13 days ago
Unlike LLM, kids have long term memory and they builds up relationships.

Real wisdom is to know when to show empathy and when not to by exploiting (?) existing relationships.

Current generation of LLM can't do that's because every they don't have real memory

I don’t buy the “it’s because of optimization argument”.

And I especially don’t buy that UB is there for register allocation.

First of all, that argument only explains UB of OOB memory accesses at best.

Second, you could define the meaning of OOB by just saying “pointers are integers” and then further state that nonescaping locals don’t get addresses. Many ways you could specify that, if you cared badly enough. My favorite way to do it involves saying that pointers to locals are lazy thunks that create addresses on demand.

It explains many loop-unroll and integer overflow as well.

Intuitively it doesn't sound like it would work. The program doesn't call listen() or accept() on the socket.

The comment section on it answered that: it's TCP simultaneous open.
j16sdiz commented on C++: "model of the hardware" vs. "model of the compiler" (2018)   ithare.com/c-model-of-the... · Posted by u/oumua_don17

Early programming languages had to work with the limited hardware capabilities of the time in order to be efficient. Nowadays, we have so much processing power available that the compiler can optimize the code for you, so the language doesn't have to follow hardware capabilities anymore. So it's only logical that the current languages should work the limitations of the compilers. Perhaps one day those limitations will be gone as well for practical purposes, and it would be interesting to see what programming languages could be made then.

The problem is: "the platform" is never defined.

When you decouple the language from the hardware and you don't specify an abstraction model (like java vm do), "the platform" is just whatever the implementer feels like at that moment.

Looks like they are trying to use this metric to justify cutting meeting / reports.

I think this is just wrong. The number of download does not reflect how important or impactful a report is.

j16sdiz commented on Clashes between web and X11 colors in the CSS color scheme   en.wikipedia.org/wiki/X11... · Posted by u/mmoogle
spauldo · a month ago
I used to use them in both X11 and CSS way back in the day. They were really common in X11, because a lot of users were on pseudocolor displays and it made sense to reuse colors as much as possible.

If you used uncommon colors in your program on - for example - a Sparcstation 20, the palette would shift every time you moved the mouse in or out of your window. It's difficult to describe to someone that's never seen it, but it's unpleasant. No one mourns the death of pseudocolor.
