Can someone help me understand this recommendation:

Under symmetric encryption, the authors write:

> If you are in a position to use a key management system (KMS), then you should use KMS. If you are not in a position to use KMS, then you should use authenticated encryption with associated data (AEAD).

These seem orthogonal to me. KMS := how keys are generated and distributed to communication partners. AEAD := how data is encrypted between communication partners using those keys.

How can it be “use a KMS if you can _or else_ use AEAD”? Shouldn’t it be “and”? What am I missing?

If an early-generation language model can produce essays that professors cannot distinguish from those written by humans, perhaps the whole essay thing isn't quite what academic snobs tend to think it is.

The solution, like everywhere else AI is making inroads, isn't to try to restrict its use so the academic dead horse can be beaten forward for a few more years, it's to think long and hard about what the future of the field can meaningfully look like.

"Congratulations, you just got your B.A. in English literature! Also, your laptop can now do everything you learned in college better, faster, and cheaper than you."

No, I don't see the problem. It seems like the proprietary shaped bluetooth speakers and their mounting points will be more of a problem in 20 years than a simple analog sound input that goes to an amp and speakers. I can plug my iPhone 14 into a 50 year old stereo. I want that level of simplicity and compatibility!

In 20 years it is going to be impossible to find replacements for those bluetooth speakers that fit in the proprietary holders they've designed. If they want to go minimalist and simple, go with analog speakers, that have a simple amp and a simple analog input that I can plug any analog source into (including a bluetooth receiver if I really need a wireless input).
WaPo op-ed: Stop the gloom and doom. The economic recovery is strong
Ok, thanks - so the "cut exactly the same way" is the key here. It's maybe not so obvious to non-puzzle aficionados? I thought it simply meant "all fit together", the "same way" referring to the overall cut.

Maybe clearer: "each puzzle piece the exact same shape"?

Though it still suffers from the issue, as with a puzzle there's always the congruity of the final image as a hard guide as to what's meant to be correct, regardless of piece shape. That's maybe what muddles the analogy most.

One nudge at the right moment is awesome. A constant red alert of status notifications both undermines their credibility and fatigues the user to the one real notification.

"42 other users are looking at this room" is 100% noise. For all I know, someone linked a picture of the sheets on Pintrest and it's people gawking at them rather than potential buyers.

"Someone else booked a similar room" is very close to noise, unless I'm in a narrow audience of needing many similar rooms and being close to the margins.

"There is only one room of this category left" has actual value, in that it is a legitimate ticking timebomb.

But it's easy to lump all of these together when they're lighting up like a user-hostile pinball machine of anxiety.

except you just described that which is called period...so it's actually good for a student to notice these things, and use the correct term, so that they can associate the name with the idea.
It's a step along the path, but it's being paraded as something close to the final destination.

Right now I'm worried about the consequences of over-estimating its capabilities - AI that almost does the right thing is going to be misused.

Rich people become rich by paying other people less than the value of their labour. Sometimes, that's to the net benefit of the community, since the value of the labour involved is increased by a superior process. Often, that is to the net detriment of the community: for example, a landlord.

The reality is, the impact of a wealthy person is almost always small, and usually negative-on-net. That's why, in the thousands of historical examples of titanic changes brought about by new ideas or state-level policies, we have so few examples of wealthy people changing things for the better.

Yes, Constraint Logic Programming evolved from Prolog, as the name implies, and because Prolog's indeterminism and backtracking is as natural as it gets for this kind of problems. While the article mentions the foundational Jaffar et al paper, there have been numerous constraint solvers embedded into Prolog ever since, known by names such as CLP(x) where x is a parameter for the domain (reals or finite domains, or Booleans as in SAT solvers), though this nomenclature suggests portability and a common approach that isn't there. An introductory article for robotic planning and scheduling based purely on Prolog and hence not requiring a magic CLP solver library and at the same time beyond constraint solvers in its ability to generate load plans in container ship logistics with an unbounded number of steps is described on the Quantum Prolog site [1]. The demo works in the browser even.

While I agree with you that free markets are a very powerful benefit to any state, you're biased in favor of it being the driver of America's success. America has access to both oceans, which means maritime access to the entire world without being able to be blockaded along the way easily. This is asymmetrical, it doesn't necessarily confer advantage the other way around. It has an absolutely massive population, and unimaginable amounts of diverse resources. These alone make for a very powerful state, no matter what system you have. Now add in that it's populace has more small armaments than every other armed forces in the world combined (including it's own), and the free markets, you get a pretty unbeatable recipe, unless theres another continent nobody knows about lurking around the corner waiting to be discovered.

Do other founders also feel the need to work alone sometimes?
Hey everyone, as a startup founder, I have an amazing team and co-founder who are all very supportive, but sometimes I just feel like getting away from everyone and working alone. As the CEO, I am responsible for various aspects of the company, including business development, marketing, community building, fund raise, game art, legal stuff, and compliances.

However, even though I sometimes work alone, I do not allow my team to work remotely from wherever they want and require them to come to the office. I am wondering if other startup founders also feel this way and what their thoughts and experiences are on the matter. Do you sometimes feel the need to work alone? If so, how do you manage it while maintaining a productive team environment?

Nintendo Is Taking Down My Videos [video]
Nintendo has been issuing copyright strikes against content creators that use gameplay footage of their games, even though it is clearly allowed by their Content Guidelines. This is mostly, but not only, Zelda Breath of the Wild content, and mostly, but not only, modded game content.

It is putting the livelihoods of those content creators in danger. Apparently the creator in question (PointCrow) hasn't heard anything back from Nintendo after contacting them about the issue.

I feel like this is yet another example of a large company acting in a way that hurts both their customers and themselves. I don't think it costs them anything to allow the creators to make that kind of content; rather it will make people more aware of their games, potentially increasing sales. The most prominent of these creators will now be very wary of posting content about the upcoming Zelda Tears of the Kingdom game which will most certainly hurt initial sales of the game.
Why do we feel this need to disect everything
We have discovered a critical bug in QNX 6 kernel in a networking scenario. There is no workaround, since the bug was in the core of their message passing infrastructure - a non-blocking by design kernel call, SendPulse(), sometimes blocks.

It took me 9 months talking to them about this problem until I managed to reproduce it on just two nodes and half a page of code, and record kernel logs that clearly showed a race condition.

We have received a patched kernel in a few days, and it worked like that for a while. This fix was merged into the official release after almost two years.

After that - only Linux, where we can see and fix stuff. No proprietary code and bureaucracy, no "fast, robust and reliable" operating systems.

Netflix blocks datacenter VPNs but you can use residential VPNs (which tbf are more expensive) to circumvent this.
That's what achieving equity means.
When you tunnel/encapsulate your traffic, many variables change at the same time, such as:

- maximum transmission unit (MTU)

- TCP maximum segment size (MSS)

- different DNS responses leading to different edge servers

- TCP reordering, which may now occur on the tunnel layer

- lost packet retransmission, which may now occur on the tunnel layer

- time to live (TTL) hop count on the packet

- IPv4 may be used for some connections that were previously using IPv6, as some VPN services are IPv4-only

- different peering between the VPN server and the edge server

ISP traffic categorization is only one variable.

It seems that a major cost of solar installations is the inverter. Power electronics that generate >100W AC power are big and expensive.

Now that more and more devices use USB-C PD for power, I wonder whether it would be possible to forego the AC inverter, and just power everything with small USB-C power supplies that have 12V input and can be powered directly from the battery.

Or maybe you could use a 110V inverter instead of a 230V inverter? Switched mode power supplies usually accept either.
Yeah I felt that pain :-).

On the ESP32-S3 ADC2 is shared with Wifi, but I don't think that's the case for ADC1. I made headway by throwing away all their boilerplate code and setting up the raw peripheral registers myself. I actually prefer it that way without all the abstraction underneath. Was getting nice results at 80kHz sample rate.

Would love to turn it into a write-up as I'm not sure anyone has done this before with that chip (at least I couldn't find any sample code around). It's actually all in MicroPython at the moment to boot... but wouldn't be hard to convert to C (and might even clean things up due to the more natural fit of that language working with bitfields). What I'd really like is to make it into a DMA-based ADC module for MicroPython but I'm not familiar enough with compiling that platform from scratch, particularly on Windows.

I run a similar toy system with a 180w panel and it makes about 110wh a day on an average from march to October - due to a similar bad position the monitoring plug would use more power than the panel makes the rest of the year :P

It runs an inverter and offsets my electricity use.

yes - my small inverter was 30EUR - its only capable of delivering about 180W. That was a significant portion of the total system cost for my toy system (with a 180W panel).

interesting that we are given a glib explanation for this phenomenon at school that doesn't quite make sense, and this finesses it nicely. In similar vein, the simple explanation of why images are inverted in mirrors falls foul of a little probing - e.g why in that case do we not appear upside-down?; there are some good deeper dives into this one on YouTube.

It's definitely a tricky problem for a student. The reason that everyone likes it is that this is exactly the kind of problem you run into when you need to solve an integral in the real world.

Once a year at least I run into a math situation like this. Obviously in some professions it will be much more (or less) often.

Exponents, floor, ceiling, and absolute value are very frequently part of the problem.

The approach of graphing the function, breaking it into components, and seeing if any of them are periodic, are all important steps toward a solution (more so than the symbolic manipulation because that might either be a big mess or even unavailable).

Often you'll end up using numerical methods to approximate the solution, but if you can come up with a closed form solution that's much nicer.
I used Swiftkey until recently, but the delay on bringing up the keyboard was annoying me too much. I couldn't justify changing phones just because of SwiftKey so instead I just went back to the default Google keyboard.

I'm still adapting weeks after changing, the most annoying issue is that the Japanese keyboard on Gboard has the key layout a bit different that the English one, so I cannot touch type on it like I did before.
I loved maths in school and unfortunately didnt pursue maths but solved this problem while sipping coffee and listening to cornfield chase, I realised why I loved maths. the solution is so simple and so intuitive if you solve with graph.
Ok, that may be but hunger and homelessness is still an issue in the US [0]. Why are there so many people living in the streets of the big cities? I live in a large city in the US. I see streets with tents on the sidewalks with people living in them. The failure is drugs, mental health issues, people unable to understand how to work the system, people unable to work, people just unwilling to work and whatever else. Something failed in their lives. We need to deal with them and fix the system so it does not fail again. You can blame the people and criticize them but that has not fixed the problem. We can say it's their fault over and over again but the problem continues. One of the richest countries in the world has a homeless problem of 100s of thousands. It's shameful.

Even from the most selfish point of view, it's a quality of life issue for everyone that lives in the big cities. No one wants to see tents and trash on their streets every day.
