True, but there are a lot of things that are also undefined at the ISA level

That feature wouldn't make any sense outside of very basic microcontrollers, you don't have any sort of determinism due to things like branch misprediction, cache misses, and pre-emptive multitasking.

That's not possible in general, for instance if you write a block of memory than execute it, you can't really define what's going to happen without including an ISA in your language spec. Another example would be executing a

Doing that would require researchers to overtly and explicitly lie, which would act as at least some disincentive.

Poor choice of term maybe... you want to get information about communication between endpoints without their consent.

Sounds like it is working perfectly, you want a MITM and this is making that difficult.

How many of these are enabled on Chromium (as opposed to Chrome) to begin with?

I've looked around before, but I couldn't find anything like this (other than DIY-style licenses that may or may not have sufficient legalese to be enforceable)

Based on the name, the tool likely makes it easy for others to figure out low-level details of processor implementations that Intel would prefer be trade secrets.

The number of bits is the logarithm of possible cases; there are only two bits needed to describe the four bases, and only 12 billion bits needed to describe the 4^(6e9) possible configurations of data.

Nope, it's due to GDPR (follow the "Sorry" link on https://devblogs.microsoft.com/oldnewthing/20190313-01/?p=10... )

"To separate the effects of fetal testosterone from postnatal socialization, the research team repeated their analyses focusing only on female twins whose twin sibling—either twin sister or twin brother—died shortly after birth, and th

"Unlike the females, the researchers found that male twins do not experience long-term consequences of being exposed to a female twin in utero."

Quantum mechanics has already been experimentally confirmed ad infinitum. If I experimentally verify predictions of Newtonian mechanics with some new configuration of billiard balls, would you consider that worthy of publication?
975.
by dooglius 8y ago
Did the results of this experiment differ from what quantum mechanics predicts? No? Then what is the point of publishing it? It's not as if different interpretations make different testable claims, or else they would be theories rather

For desktops, yes, but my default assumption for a phone is that it's on a mobile network

by dooglius 8y ago
I'm a bit confused, in what sense is accessing an SSH server not going through the internet? Was the phone connected to the same LAN as the desktop via Wifi?

The title and opening paragraph are misleading; this only leaks physical page mapping information, not data. So this can allow ASLR to be bypassed, but isn't a vulnerability in the same class as Spectre.

Other architectures have solved this problem (excessive TLB misses) by allowing for larger page sizes than 4KiB. Using larger page sizes seems like a much superior solution because you can have arbitrary numbers of larger pages while this o

Why don't the manufacturers raise the price to meet demand?

Would it have to understand the difference? You could do pretty well with a crawler that detects such fields (by checking a simple increment, say) that then spits out URL/field combinations. Then you just need to scan through those and

I wonder if he's come up with some automated tooling to find them, seems like this might be the best way to monetize if so.

It has been formally verified: http://us.metamath.org/mpegif/canth2.html So, if you don't accept the proof, you have to reject some axiom used. Which one do you have a problem with?

Anyone else get the sense this is more of a Mad-Libs style fill-in as opposed to the sort of AI-generated content found in other thisXdoesnotexist sites?

If we're talking interstellar travel, we're likely talking about spacecraft undergoing very significant acceleration and velocity. I'm not a physics expert, but from my understanding it seems that a starship would need to hav

There is BCT [0] which corrects for gravitational time dilation on Earth relative to the solar system, but I'm not aware of anything on a universal scale. It seems conceptually difficult to do synchronization if the communication round

Yeah, this more or less clears it up, I was assuming an error implied disk failure.

> To understand it better, consider an example of Linux trying to write dirty pages from page cache to a USB stick that was removed during an fsync. Neither the ext4 file system nor the btrfs nor an xfs tries to retry the failed writes.

Windows developers have access to the source code under NDA. This is much less feasible for Linux developers, obviously.
