> Flipped classroom. To better understand where students are struggling, instructors have switched to in-class activities while having recorded lectures for homework.

Hmmm. I never thought about this before, but it's kind of obvious once someone says it. It's still a bit annoying as AV is always a PITA, but it's probably effective. I'll have to think about this if I ever teach at a college level again.

> Automated grading. A long time dream of CS instructors has been to completely automate grading.

Sigh. It's almost 20 years since I actually implemented this for my CS class and and this STILL isn't the norm? Programming assignments should have online submission and testing. Period.

> Online IDEs and visualizers. To eliminate environment issues, increase engagement, and provide faster feedback, instructors leveraged online coding tools.

Suggestions that don't suck are welcome. However, generally anything less than a professional-grade IDE that you'd use for professional programming is a pile of garbage. I probably wouldn't use anything other than VSCode nowadays. Probably have to put it in a qemu container for people to run on different OSes.

> Interactive textbooks and exercises.

Yeah, no. Anything a textbook manufacturer wants to do other than be a set of dead tree leaves is a non-starter.

> Answering student questions. In contrast, instructors and TAs are overwhelmed with responding to questions and problems. These questions are often last minute, repetitive in nature, and require technical troubleshooting. For example, "Why does Python no longer exist?".

The problem is that there are two different types of questions: actual course questions and infrastructrue questions. I'm happy to deal with course questions. I LOATHE dealing with infrstructure questions.

yes, automatic upload. schedules are impractical for phones that are not connected to wifi on a schedule.

i also occasionally use the phone to take photos of items that i want to process on my laptop right away. syncthing is faster and more convenient than taking my camera and then moving the sd card from the camera to the laptop.

for nextcloud i would need to set up a server that probably also needs to be always online. syncthing allows me to backup to my laptop and is opportunistic about it, ie whenever both are on wifi.

i am also using syncthing to manage my audio files. on the laptop i decide what i want to listen to by copying the files into a specific folder, and that gets copied to the phone. when i am done with a file i delete it from the phone, and that gets synced back to the laptop. syncthing is perfect here, and so using it for backup in the other cases is worth it over having yet another solution.
I wouldn't underestimate cultural changes too. The old American WASP culture that dominated the prestigious corners of the academy up until a generation or two ago was very big on honor codes and they were largely adhered to including for things like take home tests. Now it appears everybody, including the descendants of the people who used to take honor codes seriously, considers them to be for chumps and will take any angle that they can.

At the end of the day, cheating is a cultural problem and not a technological one. Technology might make cheating easier or help to expose it, but it will never prevent it. As you say, it just becomes a game when you try. Fortunately, people can be taught to change their culture for the better, so it's not as if it's hopeless.
Interesting, but still looks like most of this could be done in 64 bits, or ~4+ billion Internets, one for each public household.

IPX had a lot of convenience features in a similar number of bits. (80, but 24 were wasted on manufacturer, so 56 useful bits)

A rotating address number will not provide privacy if the prefix attached to you is the same. Would be like saying a rotating port number would provide it, but not the case.

No organization will ever need a /64 (not even close, not even wastefully-that's 18 quintillion).

The slow uptake in IPv6 seems to imply that it's over-engineered and people don't care about these potential additional features. I'm a lifelong geek and can barely get interested. Network engineers are maybe .01% of the population.

I guess bits are only getting cheaper in the future so why not spill them incredibly wastefully at anything we can think of, is ultimately the answer. Although it doesn't answer why 64bits was not even an option.

To back up the parents claim: The authors also submitted different test studies to different peer-review boards. The methodology was identical, and the variable was that the purported findings either went for, or against, the liberal worldview (for example, one found evidence of discrimination against minority groups, and another found evidence of "reverse discrimination" against straight white males). Despite equal methodological strengths, the studies that went against the liberal worldview were criticized and rejected, and those that went with it were not. - https://theweek.com/articles/441474/how-academias-liberal-bi...

And of course, ignore Asians at all costs. Or if the study is about overrepresentation, invent a new, "Asian + white" category, and hide disaggregated numbers.

> How do we know if the explainer is good?

The paper explains this in detail, but here is a summary: an explanation is good if you can recover actual neuron behavior from the explanation. They ask GPT-4 to guess neuron activation given an explanation and an input (the paper includes the full prompt used). And then they calculate correlation of actual neuron activation and simulated neuron activation.

They discuss two issues with this methodology. First, explanations are ultimately for humans, so using GPT-4 to simulate humans, while necessary in practice, may cause divergence. They guard against this by asking humans whether they agree with the explanation, and showing that humans agree more with an explanation that scores high in correlation.

Second, correlation is an imperfect measure of how faithfully neuron behavior is reproduced. To guard against this, they run the neural network with activation of the neuron replaced with simulated activation, and show that the neural network output is closer (measured in Jensen-Shannon divergence) if correlation is higher.

This! I have difficulty understanding why more people don't view products from this angle, as this is the thinking that dominates my thoughts when considering any purchase.

Everything is going to break, that's physical reality. So how easy (cost & availability) will it be to fix? What are the consequences of things breaking? Is it just that one feature that becomes disabled until fixed, or does it take down other systems or the entire product?

The problem with TCM is that they don't accept what they don't know, they'll just make something up about "heat" or something. So while there are for sure real treatments that work, it's also lumped in with a bunch of other BS so you can't ever be sure it will work.

That's the main difference between western and TCM. Western medicine we quite often know something works (because of double blind studies) but we don't always have an explanation. TCM is fundamentally untrustyworthy in the 21st century.

And you can get placebos anywhere.

Well, for 240/4 in particular we (in a very expansive sense of "we"¹) started making the change back in 2008 in response to

https://datatracker.ietf.org/doc/pdf/draft-fuller-240space-0...

If we (for an expansive sense of "we") had kept it up more actively, we would already have had 15 years of progress on updating implementations and evolving people's expectations. That wouldn't have been a super-fast change, necessarily.

We (for a narrow sense of "we") think it's pretty likely that people will still be interested in having more IPv4 space in 15 years from now, so it's too bad that progress is (somewhat) stalled on this (with most Unix-like systems allowing it, and Windows not allowing it, and dedicated routers from before about 2013-2016 often not allowing it).

If people don't have the same positive relationship with tests that you do, I could easily see "writing tests" generate enough negative sentiment to seriously degrade a person's capacity engage the near whimsical part of the brain that allows one to think laterally at non-trivial 'distance' from the obvious problem. It could easily be as simple as writing tools is more inspiring / engaging to the OP than writing tests.
I'm hesitant to ask, because I've had to deal with professors with the same sentiment on this topic, but given the sometimes insultingly mundane and easy first semester assignments, and the fact that _alot_ of lecturers reuse the same assignments over a decade, isn't there a point where you have seen pretty much every iteration of how an assignment can be reasonably solved?

I've seen first and second semester students being accused of copying code from the internet, because they were using features of the language that hadn't been taught in class yet.

If folks where actually skeptical of the paper, you would think they would provide some evidence to back up their thought process, based on experiences from academia, or a study of crowd movement in relation to race that shows contrary evidence to the paper itself, instead of saying they can imagine the possibility of bias.

I mean I can picture an evil cabal of racists who purposefully show up in discussions like this to purposefully sow fear, uncertainty and doubt. Is that the level of HN discourse?

The ability to imagine something isn't evidence of it's existence, nor is it healthy skepticism.

All programs that you can fit on a computer can be described by a sufficiently large Markov chain(if you imagine all the possible states the memory as nodes)
Whatever the human brain is doing is also describable as a massive Markov chain.

But since the markov chain becomes exponentially larger whit the amount of states this is a very nitpicky and meaningless point.

Clearly to say something its a markov chain and have that mean something you need to say the thing its doing could be more or less compressed to a simple markov chain for bigrams or something like that, but that is just not true empirically, not even for gpt2. Just this is already pretty hard to make into a reasonable size markov chain https://arxiv.org/abs/2211.00593.

Just saying that it outputs probabilities from each state is not enough, the states are english strings, there's (number of tokens)^contex_lenght possible states for a certain length that's not a reasonable markov chain that you could actually implement or run.

Well you couldn't have had a 'bronze' age without without long and complex supply chains. Tin had to be imported from Western Europe and/or Central Asia. Same applies even more so the modern economy.

> When subsetting to non-Black pedestrians, who make up 93% of our sample, our results do not meaningfully change.

Huh. Not... quite what I think most people would expect to find in the paper, from the headline and abstract. Am I reading that right? Black pedestrians behaved similarly to non-black pedestrians, as far as staying farther from a young black man standing on the sidewalk, than from a young white man doing the same? Or have I misunderstood?
This is a really stupid paper. Their effect sizes are tiny (a 3-4" deviation??). I don't care how accurately you estimated it.

Also, they don't talk about the things that are obviously driving this. It's not race per se, it's things that correlate with race. If you live in an environment where all black and non-black people have the same distributions of behavior, you won't learn to treat people differently on the basis of being black vs. non-black. It's the fact that black Americans are ~7-10x as violent[0] as non-black Americans that is driving the behavior the paper observes. Obviously. The fact that they don't touch this obvious driver makes them, in my view, cowardly, bad scientists out for a cheap thrill.

Hey hn, this is Chris (DevRel) here at Stytch. This is part one of our three part biometrics series.

Been using Syncthing for a year or so to sync plaintext notes across my phone and PCs. Worked great, so then I began using it to sync Retroarch save files between a spare Pixel 2 I use for gaming and my PC. Worked even better! I could play games on my PC, and then continue on the go.

Recently, I switched completely off cloud storage to just using Syncthing and I love it.

Anyway, this is great software.
It beats starvation. The Nuer had three modes in this order of preference:

BTW, I'm not pro/against SPAs. It's just a tool, and like all tools, they have their advantages and disadvantages.

In general, the fact that you can update the page without a server-side round trip is a major advantage. Granted, you can also do that with server-side rendering; but then your rendering logic is defined in two places.
I think "fully supported" is a red herring; by 2001 most browsers had sufficient CSS1 support to make it workable. The sticking point then was IE5 not supporting pseudoclasses and attributes, but CSS was otherwise very much in competition.

By 2001 Flash had Actionscript, and the Actionscript wizards were in their own world, not arguing about HTML elements. All they wanted was enough HTML to serve the Flash files.

Unlike hard drives of yore where ordering the drive to write a bit at a given location results in the drive writing a bit at a given location, SSDs abstract it away as a matter of their design.

An SSD will still provide a virtual bitmap so file systems can still order it to write a bit at a given location like ye olde days, but the SSD controller ultimately decides where to actually write that bit which more than likely has no relation to the specified location.

Incidentally, yes: This also means defragmenting an SSD is not only harmful, it is outright misleading because the state of the file system is not related to the state of the bits on the drive.
