Why wasn't this part of his due diligence before contractually obligating himself to purchase Twitter?

My position is that the moderation and content policies ("community guidelines") that private companies and individuals have is also a form of expression. For example, this explains the legality of op/ed pages of newspapers p

There is simply no meaningful legal distinction between the two in this context. See https://twitter.com/badsec230takes

Imagine a scenario where Twitter and Facebook lose their ability to unconditionally moderate the content of their platforms. Presumably they would need to check with government censors first? Again, I understand how annoying moderation can

Do you have any examples of Twitter arresting or imprisoning people for speech, or acquiescing to government censorship? Perhaps you are instead to moderating their private platform and enforcing community guidelines? I understand the latte

Pat was a "boy wonder" at Intel and could do no wrong — until Larrabee. I was working at Intel at the time and remember always assuming that Pat would someday be CEO. His departure came as such a shock to a lot of us, as does his

A soft core is a CPU that is programmed into an FPGA instead of a "regular" core that is made of discrete components.

If refurbishers were able to bypass the activation lock, what would the point of an activation lock be in the first place? This is perhaps one of the most important use cases, and it's a good sign that iFixit is complaining about it.

I recall learning that the important part of the optimization phase for Itanium was based on runtime performance analysis, not just static optimizations.

Cycling. I'm in a club and ride with a group of 20+ people, 4-5 times a week. Most weeks I get at least 150 miles in. I like it for a variety of reasons: it's fun to go fast; it's individual yet also a group activity; there&#

What do you mean by the "real QuickSort"? The professor who taught me Haskell at UT used to work on Burroughs LISP machines and wasn't too concerned with caches, memory, or the like. Again, Haskell can be viewed as a language

by acallan 12y ago
Each list comprehension is O(n). O(n)+O(n)=O(n). Each iteration will roughly bisect the list, resulting in roughly log(n) iterations. Thus the one-liner is O(n*log(n)). Haskell says nothing about how lists are implemented, so with respect t

In tests and homework, we would implement the one-liner quicksort with paper and pencil, much like a math test. In a pencil implementation of that Haskell, it is n log(n). Each line on the paper represented one level of recursion. Implement

by acallan 12y ago
Like a lot of UT Computer Science, the implementation is a detail left for the reader. The semantics of the language make the one-liner n*log(n)--that's the takeaway.

Indeed, my first CS class in 1999 at UT was in Haskell. Wow! What a change it was from high school AP Computer Science in Texas, which was (in those days) C++. Seeing QuickSort in just one line was what hit it home. I remember thinking at t

The author is incorrect in the section about memory fences. x86 has strong memory ordering [1], which means that writes always appear in program order with respect to other cores. Use a memory fence to guarantee that reads and writes are me

Precisely. The latency of some of the more aggressive power states exceeds the resolution of most OS tick timers, so they are often aborted for no good reason. So, as I'm typing this reply, in-between keystrokes, voltage to the CPU can be k

It's even worse trying to explain Gulliver's Travels (and the origin of Endianness) to engineers that do know it in the data-storage sense.

Did you try '.intel_syntax'? I've had some success with it, but it clearly needs some code contributions.
