It has been one of my favourite courses because it really dives into the fundamentals and implementation of how concurrency models work, is very learnable but still applicable.

The primitives uC++ make it very easy to form the concurrency models that are present in other languages and these days the prof does exactly that and shows exactly how to implement common models, such as channels, actors, and a few others.

Everything done is very mappable to how other languages provide concurrency.
One of the most irritating things is seeing "professional" drivers using their phone while driving. I've seen countless taxi drivers texting while driving around passengers and it's a big reason why I prefer to walk 30 minutes+ to my destination over ever riding in a taxi.

Any English language articles on this, or background on why someone is describing to the court how they can hack whatsapp (auto translation got me a little ways)?

Searching is only finding Spanish language sources for info (and football info).
A reminder of the existence of obseity, diabetes, and bicycle motors exposed the force of this argument.
step back a moment, friend. your sense of perspective is completely out of whack. maybe take a moment to consider that everyone else is not wrong about this.
This is not a whatsapp hack. I cannot read spanish, but it sounds like this 'whatsapp exploit' involves downloading Android malware that installs a 3rd party keyboard that acts as a keylogger. The keylogger is used to record whatever is typed into the phone, including Whatsapp. Claiming this is a 'whatsapp' hack is clickbait.

This situation reminds me of another clickbait whatsapp 'hack' where a researcher claimed he could extract plaintext of encrypted whatsapp messages ... By rooting the device and dumping the whatsapp application memory.

After looking at it more carefully, I'm not positive that it's a failure to check privileges, although the symptoms at the time made it look like that (literally logging an unprivileged process killing a privileged one). Rather, I think it's some sort of race.

Anyway, I'm glad they fixed it now, but the response to our original bug submission didn't inspire a ton of confidence.
Chisel compiles to Verilog, so you can use that to bridge to other tools for actually synthesizing your designs.

But it brings with it the full flexibility of a general purpose programming language which makes it a lot easier to make parameterizable designs which can be more easily reused.
But this is not word games. The statement is: "Nothing is absolutely at rest." Where is the word game in this statement? Or "all is in motion." These are clear statements. If people heeded Heraclitus who said this first thousand years ago astronomy would have advanced much faster. Astronomers built a whole geocentric system by assuming that the earth was stationary. They assumed stars were stationary. These turned out to be wrong. There is no absolute rest. The academic descendants of the same academics who believed in absolute rest now call themselves physicists and make the same mistake and assume that absolute rest exists.

Interestingly, there's a globally-recognised phrase - "Only in America".

This honestly seems like exactly the sort of corruption I'd expect to hear about in the US... There's just so much negative press about your government and police that a lot of people wouldn't expect it anywhere other than America.

VR (or AR) might be good for clothing purchases once accurate full body scanning and tracking is integrated. There is no commercial tech that does this with anywhere close to enough accuracy to be helpful though. Either its rough or expensive hacks (kinect, vive tracker) or expensive research only stuff like Microsoft Holoport.
Err, yes, totally. EE definitely not required.

Very good.

Finally, someone in Rust community realized we don’t want higher-level abstractions, we just want whatever the hell our hardware can do. If that thing will go stable, I will consider Rust for a next project (BTW, doing CAD/CAM stuff for Windows).

Feature detection is no big deal, it’s just a couple of lines in C.

But I’m curious how well that thing gonna work in practice? In C++ we have low-level control over memory layout allowing to place these SIMD vector values in STL containers with correct alignment. We have function pointers with vectorcall calling convention that enable implementing CPU-dependent routines very efficiently. The compiler inlines a lot of that SIMD code. Maybe you know how much of that applies to rust + stdsimd?
I disagree, even if you don't care about banter, a capable host will be able to drive conversation and get panelists/guests/interviewees to express themselves better (even if they are typically awkward in front of a camera). I see it all the time in professional esports streams.

I'm not going to bother listing out the litany of odd UI issues present in macOS, because you can Google it and find this within a few seconds. It comes up every. single. macOS. release.

Nobody cares about learning a new UI because most of the tools they use are webapps nowadays anyway, which require this.

The value isn't yours, if that wasn't apparent. For the vast majority of people who use apps with easier to implement design/UI/UX features, it's easier for them to get things done. These apps wouldn't have caught on without that.

And lastly, you've opted to be incredibly pedantic in an attempt to be snarky (I'm guessing, otherwise I've no clue why you'd do this). Electron is more than memory issues and this isn't even a debate.

I agree the Web is messed up today thanks to big tech doing whatever they feel to defend their empires. But they will overstep (enough examples from the past) and when they do it creates the right kind of pressure for alternatives. Don't have any delusions that the web standards you know today, just fell into place cause some old altruistic wise men sat together out of joblessness and came up with things that were good for the world. Things don't work like that. Good people don't come together to do jack until they are highly frustrated and under pressure.

2024: IoT voting machines are deployed to a majority of US polling places. Peter Thiel is elected President in a stunning upset.

2025: Tavis Ormandy dies in a tragic IoT jetski accident.

2030: All new cars are required to have fully autonomous and connected control.

2040: Cars produced before 2030 are taxed at 50% of their initial purchase value per year.

2045: North Korea deploys its long-held stockpile of cyber-weapons against the perceived EuroAmeriUnion threat, causing mass fatalities in IoT cars. Since North Korea's vehicles were all produced before 2030, the EAU is forced to fall back to a nuclear response. In its last, desperate act of retaliation, NK's leadership releases its cyber arsenal on the public internet.

2046: In the ensuing nuclear winter, hacker gangs desperately rampage through the Internet of Things in search of food and fuel. Only those with non-connected possessions are unaffected.

I'll be dead either way, but it's not hard to imagine the IoT turning ugly.

At the collegiate level, the goal (opinion statement) of education is creating deep understanding, higher level thinking, and life-long metacognitive and learning skills.

Nominally, yes. In reality? No. The reality of higher education is to act as a preliminary screen for employers. Few people who apply to well known schools get in. Fewer still survive to complete their degree. Many switch programs (to a less competitive field), drop out, or even commit suicide.

I wish universities were as committed to education as they say they are. But we wouldn't have people failing right out of school if that were the case.

The satellite antennas used to uplink a video feed like this have a very small beamwidth (around 1° depending on antenna size and the frequency they're using), so you need to keep them pointed precisely at a specific point in the sky. They rely on a sensitive IMU (accelerometers) and fast motors to actively track the satellite while the platform moves. They're quite impressive to watch in action[1], but I'm guessing they're no match for the shock and vibe of the rocket landing.

I think bandwidth isn't the issue. You can do 360 with a 4k feed. I expect it was more of a issue of hardware that would make it past Mars without space killing it.
The neutrino observations are a datum. Along with much other data and reproducible experiments, this can be helpful in furthering our understanding of the universe around us.

But it is not a reproducible experiment, it is simply an observation. It can be the basis for creating reproducible experiments that will further our knowledge.

But if it is a one-off observation then it can be given no more significance than that.

I think the upshot of what the author of the article is highlighting is that there is little incentive to do the replication experiments as this does not give any significant recognition or other funding opportunities.

Replication required having all (or most) of the information about the original experiments and being able to confirm the original findings. It has been commented on before by others in various science fields that this information is not available for many experimental reports.

It is also known that if anomalous results are obtained that contradict prevailing theories then it takes a brave and hardy experimenter to continue pushing those results.

When it boils down to it, scientists are no more honourable or upright than any other segment of society. They are people too and as such, like all the rest of us, have foibles, follies, biases, etc. that can get in the road of furthering our knowledge.

Live Share is different than other collaboration tools in that it supports Language Features and Collaborative Debugging. By Language Features I mean all participants get auto completion, go to definition, error checking etc. Collaborative Debugging allows multiple people to step through code, inspect variables or look at call stacks.

I don't know why the GitHub doc get linked, but this page probably gives more context: https://code.visualstudio.com/visual-studio-live-share

Disclaimer: I work at VS Code and have tried Live Share in private preview. Honest feeling is it still has some gaps, but if everything would work out of the box it can be pretty awesome.
Trivia: Why they are called "cache-oblivious" and not "cache-aware"?

The paper that coined the term is here: http://cacs.usc.edu/education/cs653/Frigo-CacheOblivious-FOC...

Basically, there were first cache-aware algorithms that assumed certain cache sizes and other properties. "Cache-oblivious" algorithms were a refinement that worked well for many cache sizes.

All in all it's silly that the "cache-oblivious" term was the one that survived, because now cache-unaware and cache-oblivious algorithms mean the opposite things - contradicting the dictionary definition of oblivious.

This is the kind of thing I expected after they started the “don’t be terrible” policy following dbag looking for dead people.

I think the better option would be to allow advertisers to have an ability to blacklist certain channels completely. But given the quality of web ads maybe that would not be sufficient?

I assume they now have a policy banning “how to make a bomb in 3 easy steps” but the phrasing of the rule necessarily captures “I made gunpowder at home to do science”
There's some confusion here about what "you" means. I can't imagine how an individual developer at some firm would receive an NSL individually. So it's the firm that would be deciding whether or not to hire outside counsel.

I guess "amazing science" wasn't strong enough for you. If we were able to look around 360 from the POV of the driver, rather than getting the two feeds, it would be better. It doesn't cost a lot to put a lens on the camera you have, provided it was high enough resolution. Even a 1080 can do 360, but 4-8k is better.

I'm not sure what happened that was new here other than the PR of putting a car into solar orbit. They landed their 20 something rocket vertically. They crashed another one or something.

It just seems like a lot of expense and science to stop at a normal camera.
You say "inertial reference frame at rest with respect to any massive particle..." Is your particle moving with the reference frame? I believe so. How is it at rest then? Do you have motion when you are in a plane? Or do you say you are at rest because the passenger next to you is moving with you?
Really cool to see this built into the editor. Getting over the hump of “well I could install this 3rd-party extension, create an account, and follow directions, or I could just walk over to my coworker’s desk for the 15th time” is probably a big barrier to adoption.

> what's happening with smartphones/tablets that suddenly makes them incapable of performing the same tasks

Competition, that’s what happening.

On PCs we had no competition for many years, that’s why performance has stalled. For example, cpubenchmark.net gives 8739 points to i7-2700K from 2011, and 12078 points to i7-7700K from 2016. Very modest 38% improvement in 5 years and 5 generations of CPUs. Same 4 cores/8 threads, same 8MB cache.

I can't answer that definitively, but my preference is for team competitive sports, which is probably related to the motivation to perform as opposed to scratching a genetic itch.

Agree that the article was flimsy, and that's putting it politely.

Whether it's a function of age and cynicism or not, I'm not sure, but I'm much less fanatic about watching sports than I used to be. Jerry Seinfeld was right when he said that we're cheering for the uniforms. My home team for my sport-of-choice to watch is maybe 10% local talent and the rest are imports, and even the local ones don't necessarily stay put from one year to the next. Makes me care less and less.
