The role of quantum mechanics was originally to describe the behavior of individual atoms and molecules. This is the way of the Schrodinger equation or matrix mechanics, the harmonic oscillator, the hydrogen atom, infinite-dimensional Hilbert spaces, quantization, and so on. I would like to call it "hermitian" quantum mechanics since the Hamiltonian is a hermitian operator.

Then there is the quantum mechanics which describes engineered quantum systems like quantum dots and quantum logic gates. Here time evolution is in discrete steps, Hilbert spaces are finite-dimensional, and probabilities are discrete instead of continuous. I think it is apt to call this "unitary" quantum mechanics since one essentially only considers exponentiated Hamiltonians.

It is important not to confuse the two. If you know hermitian quantum mechanics then unitary quantum mechanics is conceptually straightforward. If you know unitary quantum mechanics then you will have a lot of new concepts and mathematics to learn before you understand hermitian quantum mechanics (but of course you may know more about applications).

The programs mentioned in the article teach unitary quantum mechanics: sufficient for engineering, insufficient for physics. If we assume that the engineering world is becoming increasingly quantum then it is perhaps not a bad thing.
Ha. Like the people who take the long way to avoid sitting in traffic. Even if it takes longer, it "feels" better.

Weak means that a mathematical flaw has been discovered that makes it inherently insecure, or that it is so simple that modern computer technology makes it possible to use “brute force” to crack. Strong means that it's not either.
Was he talking about culture? Because I’m not familiar with any movement attempting to get people of lower intellect included in creative processes. Modern inclusivity in the arts instead tends to involve gender, skin color, and sexual orientation.

But the article does have some very good points, even if the author’s usage of the word “woke” could get him some flak. I definitely feel audiences (and even critics) tend to increasingly view art through the lens of moral rectitude.
so I had this thought - we should flood the zone with fakes. All out.
Systems like Clearview and pimeyes, and intelligence agencies would have a lot more noise to deal with as fake detection is expensive per photo and by definition, always lagging behind the cutting edge fake generator.

I would also be surprised if governments aren't also sewing distrust with their enemies by generating fakes of government officials in past random photos of graduating classes of military academies of foreign governments, just to sew chaos. And why stop there - are you a middle-management cartel member with low prospects for advancement? Find a higher ranking cartel member you want to get rid of, start generating their face in older real photos of FBI graduating classes. Who knows, a position might open.

It's a new world.
it looks basically the same in structure whether it is the
biggest Rails app there is or a new one

Totally agree! Developers tend to really undervalue this aspect of RoR.

In addition to easier onboarding, it greatly reduces bikeshedding.

MVC maybe isn't the best paradigm for everything, but it's good enough for most things.
Depending on jurisdiction, you may find that this isn't exactly the case.

So there are a few issues with this, WAFs do have their uses, generally speaking yes rules based on regexes looking for sql injection are silly.
But they do have their useses. For example tarrgeted blocking, https://confluence.atlassian.com/security/cve-2023-22515-pri... . While waiting for the patch, a WAF can quickly block all requests to the /setup endpoint.

I would also say that static analysis as a panacea for SQL Injection is laughable. SAST tools have a hard time finding sql injection in code. As they quickly loose track of user controlled data. They almost always create false positives / false negatives when Parameterised queries are used incorrectly. For example when user controlled data gets into the SQL query rather than the parameter of a paremeterised query.
And that completely ignores SQL Injection attacks that do not occur within your code directly, but in libraries you are using.
I have flipped burgers, assembled camcorders, and driven airport shuttles. The thing about those jobs is that the workspace was well designed by someone who understood the tasks. Writing quality software requires long quiet concentration, yet we keep cheaping out on open plan desks.
Is the content of the article not exactly what the headline says?
Qualyss WAS - don't get me started. Generic accounts, short passwords you can't change, incredibly slow and not-able-to-debug scans. Numerous false positives. And with a crawler you don't truly know if you've covered everything.
i get you now, and i agree. these feel-good activities are obviously not effective, but to me that also means that they don't have an impact either, unless you count making people feel good as impact. in other words i see impact and being effective as closely related. i guess my point was that the examples you used at first were not the kind of bad examples that you give now. at least to me.

i see having local impact as something very important. but i have not looked very closely at EA yet, and maybe EA does not consider that, i don't know.
If so many adults still feel like a kid, why do many seem guarded and overly serious?

> because anything that queries in rails uses AR and that's often done in both lib code and controller code

How is that different from any other framework ever? You have to query the DB somewhere. Rails makes it incredibly easy to swap out databases. Much more so than any other platform I can think of.

Nothing is making you use AR at all. This is a non issue.

In those cases you can just do error recovery in the parser (truncating an erroring function for example) and then store out-of-band information necessary to reconstruct the original file

This is also necessary to deal with whitespace for example (if you just reformat the code, you didnt change the ast but you changed the file)
WAFs are also bring on risks that are not considered. At least in scenarios where things get logged and no one considers how they are sanitized. And then there is also GDPR in Europe.

Lot of these issues could be avoided by good API design. But if you need WAF you might not be doing that... So you end up passing tokens as parameters and they end up in logs. Then again if someone has access to them they probably also have other access. But it still is often forgotten aspect.
>So, Bard can now access and analyze your Drive, Docs and Gmail!

I asked Bard if I could use it to access gmail, and it said, "As a language model, I am not able to access your Gmail directly." I then asked Bard for a list of extensions, and it listed a Gmail extension as one of the "Google Workspace extensions." How do I activate the Gmail extension? "The Bard for Gmail extension is not currently available for activation."

But, if you click on the puzzle icon in Bard, you can enable the Google Workspace Extensions, which includes gmail.

I asked, "What's the date of the first gmail message I sent?" Reply: "I couldn't find any email threads in your Gmail that indicate the date of the first email you sent," and some recent email messages were listed.

Holy cow! LLMs have been compared to workplace interns, but this particular intern is especially obtuse.
> It's funny that the traditional diamond industry started to argue that these lab-grown diamonds were too pure and lacked the impurities that natural diamonds have.

I guess they're doing that because humans have a long history of idolising old times and old imperfections. We praise analog photo grain, or analog audio noise. Industries from clothing brands to guitar manufacturers release artificially aged products.

Then again, adding imperfections in "post production" seems to be the status quo.
There are things like M5Stack (also ESP32-based) that suit some purposes.
While I don’t discourage learning a new language the immediate toss aside of rust on esp32 was perplexing. It sounds like a lot of the memory issues would have been mitigated by sticking with a language better understood. Rust’s esp32c3 support is pretty good IMO, that’s all I use. Writing in C++ makes me feel dirty in ways that even COBOL doesn’t.

I also think I would have implemented presence by TTL, updating the TTL for each MAC when I see it and purging a TTL heap before updating my remote statistics. I didn’t fully grok the approach taken for maintaining the hash map, in a taxi off a long flight, but it didn’t seem super robust on my quick read.
A lot of web apps fetch data from the server prior to rendering; and the data that's fetched is often necessary for rendering. I suppose for things like a "control panel" that doesn't have much data on it, HTML Web Components might work fine; but a lot of use cases need non-stale server-supplied user data. I guess one other use case is caching stale data in local storage, and rendering that -- but even that requires JS.
After you receive it, you can take it to a jeweler for confirmation. If it was falsely represented, eBay should back your return claim.

That's interesting but the obvious useful thing is to have GPT-4 write queries and create reports for the user. Which I have built before and it can do it easily for many types of user requests.
> "Going to an empty office": why in the first place?

I don't understand what you're asking here.

My point is that a remote worker saying, "You work in the office while I work at home" is dissatisfying to many people who like the idea of working with people in person and who dislike collaborating with others who are working remote.

> If there are so many people missing the office life, why don't they go to the office? Why do they need to be forced?

Some people don't miss the office and need to be forced to go to the office – if the company decides they want employees in the office.

I don't get what you don't understand?

If a company wants all its employees in the office then allowing some to WFH isn't going to happen. If a company wants all its employees to WFH then working in office isn't going to happen. If a company wants a hybrid solution where some employees WFH and some work in office then it's going to be dissatisfying to those who want all employees in office.
Would it be practical to integrate pumped hydroelectric energy storage into a canal lock mechanism? Pump water up to lower the water level; harness water flowing back down for electricity; and arrange the timing partly towards grid supply & demand.

Maybe dig a third reservoir adjacent to the lock mechanism, as a buffer between the two levels, to give you more flexibility with the timings.

[late edit]: Apparently this is in fact a thing, in some cases:

- "The hydraulic cylinders enable the water used by the locks to be pumped back. Up to 48,000 cubic metres of water are displaced in a single lockage operation. In periods of low discharge on the Meuse, the screws can pump back the water lost due to the passage of a ship through the lock to the upper canal reach. In normal periods of enough discharge at the Meuse, the screws are used to to generate green electricity from hydropower."

> Why would they agree to that anyway? surely individually licensing AV1 patents would be much more profitable?

They won't agree to that. They are already not agreeing to that.

The two options to keep AV1 royalty-free are their claims are found to be invalid in court or they get bought off via a settlement.
It's gotta be my favorite AWS service for this reason alone. It's almost useless but that's a feature not a bug. They knew exactly their market.
I haven't noticed. I see a lot more mentally ill people on the loose, but not really any perceptible increase in crime. I'm hoping they hover one of these over Flatbush and Dekalb and ticket all the drivers weaving through pedestrians.
Does ubiquitous computing need interface agents? (1992) [pdf]
I worked on a very large production rails app from 2015-2019 and came away loving Rails and hating Ruby. Give me Rails in TS or Go and I couldn't think of any reason to ever use anything else for a web app backend.

The Rails Console has to be one of the greatest productivity enhancers I've ever come across.
Excluding Diff Eq, the rest of the mathematics are standard if you are doing e.g. machine learning. Diff eqs are not that hard to pick up anyways. At higher levels of ML and information theory, the math involved in statistical mechanics are covered too, for example Ising models are generalized into Hopfield networks and message passing/belief propagation. Most of quantum computing boils down to a few very specific matrix gates. The actual finicky physical details have very little to do with the algorithmic implementations. Classical mechanics and EM are irrelevant here. You hire quantum computing people to figure out the algorithmic and compute stuff, if you want somebody to debug waveguides, there are plenty of unemployed EE graduates.
> so I had this thought - we should flood the zone with fakes.

This seems to me like the worst possible thing to do. We already have a serious problem being able to determine what's true and what's not. A response like this would make the problem so much worse that it could pose an actual societal threat.
There are thousands of ESP32-based IoT devices on AliExpress that would disagree with you. It's an SoC chip not a "pcb".

It'd be neat to see something like Kubernetes SPIFFE for identity/sso combined with something like Kubernetes Gateway API for front-end routing.
I searched the comments page to find you were the only one who mentioned them. I think we had a 20 MHz 286 with a Weitek coprocessor when I was a kid.

It seems Weitek also had a coprocessor to go with 386.
For my graduate algorithms course, this was by far the book that fit my brain the best. Can't recommend it enough.
WAF don't require a team of security engineers to babysit.

Cloudflare, AWS, GCP etc offerings are basically just one click and for smaller sites will be free.

And over the years there have been many security flaws in how SQL libraries actually handle parameterisation.

That's impressive. I've seen a 2" butterfly valve attached to a stepper motor blown clear off the tube it was on because it closed too quickly. Oops... expensive lesson.
You gotta be careful with this one in the context that it is being applied here (HTML). This risks becoming an ableist mantra because the practice might be disregarding accessibility concerns.

Awesome! I feel so much better about using this to pass an audit.

Not to mention that there are fairly steep piloting fees for the Magellan strait. I wonder if USN carriers take on pilots when they navigate it or if they have a political exemption.
Those things are happening. However it is a decade at best from something in a lab to something in general use. That is at best, quite often things work in a lab, but don't work in the real world. sometimes not work means it works, but the side effects are worse than current treatments (or even worse than doing nothing!) Sometimes it works on a sub group of people and we need more time to figure out who/why it works on and then target those people.

if you look at day to day or even year to year it looks like things are not moving. However if you look at decades things have gotten much better.

Always surprised to see people running around with their Bluetooth needlessly enabled.

Maybe I worry to much about battery usage, but I just got used to always enable WiFi, Bluetooth, or NFC, only at the moment of usage, and disabled afterwards.
Can, perhaps. Do: not so much. Most stations don't even have turnstiles, instead preferring some occasional posts you are "suggested" to tap your card at. Those that do have turnstiles without fail have handicap-ready turnstiles, which look enough like a completely open walkway to pass all forms of "plausible deniability" - especially when you see everybody in the station lining up to go through them.

The only people I know who do pay are paying from company-provided passes. Everyone else is riding off them.
I don’t believe that this type of thing hasn’t happened, but the article talks about ISDN and even in the early 90s that wouldn’t be very common for a non branch office. Then they talk about traffic shaping/QOS and that’s when I call BS. I don’t think the Cisco 2500/2600 routers (which basically everyone used) even supported those features until many, many years later.

Maybe they were talking about T1?

I'm not a math or a CS expert, but I naively "designed" a PRNG which was simply repeatedly doing hash(random_seed+counter).

Obviously you have to keep random_seed secure, and use a hashing algorithm that does not have easy collisions, but other than that, is there any actual downside to this method?
We're not talking about some survey of self-reported symptoms of nausea with N=113. We're talking about satellite data, glaciers, permafrost, ice cores, tree rings, tide buoys, written historical records, weather stations, geologic records, bird migration patterns, extinctions, even human experience in a single lifespan. (And yes, of course, computer models). We're talking about ecologists, geologists, atmospheric scientists, space scientists, biologists, foresters, environmentalists, militaries, space agencies, researchers from every nation on Earth. There is just no room for doubt anymore, except motivated denialists and conspiracy theorists. The questions that remain are how fast it is happening, how quickly we can adapt, and whether any political change is possible to avoid its worst effects.

I personally take umbrage at the suggestion that Science is somehow populated by fraudsters, crackpots, and failures. When in reality all that I have seen is the Science is populated by anxious, detail-oriented people who are extremely embarrassed to be caught making mistakes and are generally extremely cautious. Do mistakes occur? Yes. Do misrepresentations occur? Sometimes. Does fraud occur? Extraordinarily rarely. And in all of these cases Science has a culture of dealing with honest mistakes, of dealing with distortions and misunderstandings, and punishing fraud. It's career-ending to be a fraudster in Science. Unlike most of what culture seems to be devolving towards today, which just shovels more BS and gaslighting. Science is doing its best with imperfect people to move forward. It's all based on reproducibility and banishing the bullshitting.
The Flexport CEO said it was an LNG (Liquefied Natural Gas) carrier. https://x.com/typesfast/status/1724150162531201571?s=20

Keep an eye on whats going on at the Panama Canal. An LNG carrier just paid $4 million to jump the line. This will likely be more common for LNG carriers as their cargo will literally boil off sitting in the hot tropical sun, but it will be interesting to see if container ships end up having to resort to similar measures as transits continue to be restricted due to the ongoing severe drought.
A US government backed SMR just quit their pilot project as they can't compete on cost in the current market. Nuclear is basically obsolete. We need to subsidize it to safely use all the current waste and while extracting energy turn that into safer leftovers.

It's much easier to use direct hydraulic power from inland upstream fresh water bodies. That's how most locks work, you just let gravity do the work. This is super basic technology that can still reliably move up million ton cargo ships.
