Recent gatech OMSCS graduate here. I fail to recognize any real issue with proctoring. I have used proctortrack and honorlock.

* proctoring software can be installed before an exam and uninstalled afterwards. It doesn’t need to stay on your pc/browser, and its activation is very obvious. I have no info about permanent security issues caused by such software.

* what proctoring does is mostly recording video and audio (possibly with room scans at the beginning ) and uploading it to a remote server for later verification. Then, such footage is automatically scanned for anomalies. The teacher can then check what happened in flagged content parts and choose what to do. The system does not impose a “cheater” label by itself.

* proctoring systems don’t force a closed book approach. I took open book exams where the only enforcement was “be alone and no collaboration with other people during the exam”.

It seems that some people are concerned with some very specific details of some implementations, or with shitty teachers that say some people cheated just because they were flagged for whatever reason.

Some things that happened to me and I still passed the exam:

* a coworker accidentally entered the room where I was taking the exam and I had to talk with him to send him away.

* I had to change my position since I had setup my laptop in a way that was unbearable for a many-hours exam, and I briefly exited the webcam view.

I contacted the teachers when this happened and I got no issue at all.

Of course some teachers happened to be silly, at the beginning of the pandemics: I heard things like “no drinking, no eating, no restroom” for 4 hours exams. Blame the people, not the software.
Headsets also emit radiation in order to talk to the phone, though. (Potentially less than the phone though since they need to cover a smaller distance.)

>> Greenspan had stated that growing worker insecurity is a significant factor keeping inflation and inflation expectation low, thereby promoting long-term investment

This is modus operandi of the system. Its by design. A worker that has a mortgage, car on loan and bills to pay cannot mouth off to boss, cannot complain about long hours and lack of pay increase. They risk their whole life to collapse otherwise.

That is a perfect cog for neo capitalistic machine.
I can't comment for others but I didn't read it that way. I just knew the context and thought people might want to read about it, because it is interesting. Thanks for bringing it up in the first place.
Yeah, I remember when the first CMOS sensors with phase detection elements started showing up. This is what I meant by "conceptually similar" although I probably should have clarified, since we've had massive sensors without these elements for longer.

I guess contrast-based autofocus is what really needs the DSP, since you need to do edge detection / FFTs on more patches of image for the technique to work well, as well as PSF analysis if you want to guess the lens defocus direction. With phase it's just a few cheap 1D correlations, and you get accurate lens direction information for free, which explains why it feels so much faster.

Unfortunately we didn't have access to an electron microscope, so a modern mirrorless camera would have made for a rather less interesting teardown.

Could you run Linux on a 286?

Back in the day I remember there being a project called “elks”, the embedabble Linux kernel, which attempted to achieve that, but it wasn’t a ‘full’ Linux IIRC.

(Edit - looks like ELKS is still with us, primarily aimed at 8086 - https://en.m.wikipedia.org/wiki/Embeddable_Linux_Kernel_Subs... )
This is a topic close to my heart and I am trying my best to create a serverside platform that can only run open source software.
My hope is making digital services transparent half the shenanigans will go away. For two reasons

1. bad actors can't hide B.S.
2. good actors have something they can point to that has 3rd party validation.

So for digital services where the source code is always available, my runtime dynamically loads the source code indicated in the URL each request. So you are free to go to the URL directly, and you can figure all the routing out in advance of data leaving your device (in theory).

For the sake of moving fast, the 1st supported code repository the runtime can run serverside code from is Observablehq, which has the additional property of being a code IDE which simplifies greatly how you actually upload code to a public location.

The core building block:

> An important fact about assignment: assignment never copies data.

Is that really what's going on here? I'm in way too deep to be sure what's best for beginner programmers, but I feel like Python must surely optimise...

sheep = 1
goats = sheep
sheep = sheep + 10

... by simply copying that 1 into goats, rather than tracking that goats is for now an alias to the same value as sheep and then updating that information when sheep changes on the next line.

Now, if we imagine those numbers are way bigger (say 200 digits), Python still just works, whereas the low level languages I spend most time with will object because 200 digit integers don't fit in a machine word. You could imagine that copying isn't cheaper in that case, but I don't think I buy it. The 200 digit integer is a relatively small data structure, still probably cheaper to copy it than mess about with small objects which need garbage collecting.
Was that a curveball? Nobody had told you beforehand?
I no longer evangelize for Linux.

The hardware support is good enough that it just works, and has been for a decade. In that period I've seen the desktop become worse and worse in the name of 'accessibility'. Since I can't get the people in RedHat to stop making the desktop worse my next best alternative is to make Linux toxic enough that there is no financial incentive for them to continue and simply leave.

Anyone non-technical who ask about windows alternatives I merely tell them that Linux is too hard and they should stick to Windows. Gate keeping is a virtue that we need to practice more of.
You are not wrong and I agree but eventually I suspect there will be some project management (following up on peer reviewers, winnowing out the low quality papers, etc) that will need to be paid for on top of the server and bandwidth costs. Whatever service comes about it will need to collect some money. My view is it should be small in the single digit dollar space for unlimited monthly access for every paper that was funded by a tax payer in the world.
That sounds extremely interesting and want to know more.

Displacing all this onto “software” is not credible in my opinion. Companies build these things, people with incentives and motivations inside the companies make the decisions that lead to the outcomes we see.

Take the next step and look at how these things happen and why. Nobody should “trust software” to begin with. That’s a meaningless phrase and idea, like “trusting information” - where did the information come from, whose purposes does it serve, what have they omitted?

Time to put on our big boy and big girl pants and stop with the utopian stuff. Ask why, to what specific end, does Microsoft put ads and tracking in their products? Not, why did they crap up the nice good software with things I don’t like?

I might have been a bit unclear. Not every request gets a new process, but there are a pool of processes. For instance gunicorn will maybe have ~20 processes ready to serve requests, with a main process sending work to the workers. Since it's different processes, there is very little communication or shared resources between them. It's almost as if you're running your main entry point multiple times in different terminals, just with gunicorn managing it for you.

This is different than for instance java, which there is one process and then multiple threads. But because of the GIL in python, only one thread can ever run at the same time (in the same process), therefore one has to launch multiple instances/processes of the application.

width: 410px;

Because when sized to 400px it always clips 10 pixels of the canvas.

I added a 64GB drive to mine, increased the RAM to the max supported (2GB? 4GB?) and used it for years with Debian, after running it as a hackintosh for a while.
It’s been a minute since I used Android, but I definitely felt the same when I switched to the iPhone. I found it a much more refined experience over all.

That said, if there was a decent Linux phone, I’d hop on it, warts and all. Pinephone or Librem are getting close.

“ram effect” isn’t something I can Google (I get pages about farming); the closest I’m familiar with given the context would be ram compression of air intakes in engines, but that’s for increasing the mass flow though the engine, not energy recovery.

The only engine I’ve heard of that attempts to use the ISM as a source of fusion fuel is the Bussard ramjet referenced by @ClumsyPilot (which uses an EM field), and as they point out, it’s been demonstrated to be a net-loss not a net-gain. An easy way to intuit this result is that the energy per particle of a fusion reaction is similar to the 14 MeV per particle (0.82-22.4 MeV for the most promising reactions) which I used as a starting point in my calculation.

You’d actually have to decelerate the ISM from the frame of reference of the ship in order to increase the rate of fusion to its maximum, but even then most nucleon impacts do not cause fusion and instead bounce, slowing you instead of helping you even if you can solve the problem of efficiently using the energy of any particles you decelerated at the front of your ship to accelerate them again at the back.

This is the problem with simplistic slogans like "transwomen are women" - it shortcuts analysis in favour of an ideology.

If instead we start from the biological reality, which is "transwomen are men presenting as women", and take it from there, a much more reasonable conversation can be had about where these trans-identifying men should be politely regarded as women, and where they should not.
It's the same dilemma though. Now you are raising the humidity around you, making other peoples' sweat less effective at cooling them.

I have a superstition: I don't see a robust future for Sci-Hub, Internet Archive or Wikipedia.

There is a legitimate argument in the value added of curating research into journals. The publishers don’t do this. But simply eliminating that curation mode is unlikely to be feasible.

Gamification in Fintech: Examples and Best Practices
It's difficult to make financial services engaging since it's all about tables, charts, and numbers.

Thus, adding gamification to fintech solutions is one of the ways to meet the challenge.

Game-like elements help financial businesses engage users more effectively and turn routine tasks into fun and rewarding activities.

Gamification helps attract users to an app and keeps them engaged in it for longer. That's a huge benefit if you want to make your financial service more appealing or shape user behaviour.

According to Statista, gamification investment skyrocketed from $4.91 billion in 2016 to $11.94 billion in 2021.

Some companies are even exploring the potential of the gamification of investing, and the combination of gamification and blockchain technology.

However, an app overloaded with gaming mechanics can make a financial product look unreliable and suspicious.

The challenge is for companies to find the golden ratio of gamification that livens up an app while still keeping it all about serious business.

Woz also got into hacking about computers at an ideal time. Not long before then it would have been impossible to build a sophisticated computer in your garage. Years later, miniaturization has continued to progress and many things that were once relatively simple to replace have become much harder.

When most parts on a computer were through-hole components and relatively large integrated circuits that could easily be hand soldered, the skill required to participate in the repair process was much lower. Today, even relatively open hardware like a desktop PC has a ton of added complexity that would make people far less likely to ever want to attempt a repair on their own. While I've reflowed solder on a faulty GPU in the oven before, that's not exactly a good idea. A person is usually going to replace the things that have been component-ized like the RAM, GPU, SSD, motherboard, etc. rather than try to actually repair them.

Granted, when a component like that breaks on a PC you can just pop it open and replace it, rather than having to find a specialist to repair a laptop or phone where all the parts are glued in or soldered. While I can sympathize with people that do want that (there are projects out there trying to bring products in this category to market), I'm personally okay with that being the niche that it is. Most people didn't hack their computers back then and to this day most people don't hack on their computers.

There probably should be components available for experts like Louis Rossman who can replace these parts. There probably should be schematics available so they can more easily make these repairs and they can have businesses like his who can specialize in doing these sorts of repairs (they already do exist, clearly). Companies like Apple absolutely should not be using any sort of DRM to prevent use of third party hardware components in repairs. Going out of your way to make your devices difficult to repair is unethical. But I think we're well past the point that someone without specialized skills should be able to expect to repair any device that they purchase.
We don’t know what we would have had. I could imagine Apple having solved the aesthetics while also keeping it hackable. My guess is they’d have come up with a LEGO-like approach to internals, using crazy materials science to find some way to get the blocks thin and strong.
My institution is currently undergoing a review of our assessment policy and I am participating as a stakeholder.

Nobody, academic or otherwise, wants to use e-proctoring ongoing. It was a kludge for sudden covid in 2020 but ongoing use will be restricted by policy to where it is used to accommodate a student's need for an alternative assessment arrangement.
I’ve used the pattern several times of “select these SQL objects into a cursor, then iterate over the cursor to assign/revoke/check permissions on the objects”.

It’s still in a single batch of SQL (stored procedure in our case, so no additional network roundtrips), but the code is vastly clearer to read/maintain this way.
Your assumption is they can keep rates low while inflation goes wild.

That’s not an option either.
> Is it possible to do the latter, but still have end up with a well-curated source-of-truth for your data?

It's important to get the core centralised data infrastructure up and running (even if it's dirty af) as that helps with the bulk of the data work.

The oft quoted not completely true but kinda true statistic is that 70% of data work is finding, cleaning and storing the data. Analysis and modelling is the easy bit.

You could do it the other way around. Hire some data people in each team and get them to meet up every once in a while.

But I'd wager the central data stuff that makes everyone's life easier will get pushed back behind the "urgent" team work every time.

#ConwaysLaw

Edit: it's possible to do both btw. E.g. Have a bunch of centralised data engineers that do the heavy lifting stuff. With data scientist/analysts embedded in teams doing the fine grained modelling stuff. It's not a binary choice (once things are up and running).

> My (uninformed) impression is that data-driven is responsible for rather a lot of rot.

Somewhere between step 3 and 4, I assume the publisher gets hold of the paper and acquires a license to resell it? How does that part work and why do universities/academics support it if they could just distribute it for free or via an open journal? Is it solely to get the "kudos" of being in particular publications?

I would humbly offer the UK as a counterpoint to all these creative fields and add TV output to the mix. Not to get into a US/UK pissing contest but to highlight the UK has very healthy culture output with a lot of talent.

I'd also suggest "better" and "more dominant" as 2 different things. The latter can be the case through marketing and commercial factors not merit.

Look(ahead|behind)s do not consume any of the string which is probably where they confuse people.

I see non-look regexes as stepping over each of the characters where you can never go back in time - once a char is stepped over it is gone.

“Looks” allow you to step over characters to true|false match them, then step back in the string as if the look did not exist.
