I work in the industry. There are a couple of reasons they don't work, at least as currently used.

1) Over saturation/overused: Especially as High Schools begin using these, students get too many, too frequently, and it just becomes a sort of background noise. Back when students still had email as their prime mode of digital communication, we had the exact same issue. Studies on their effectiveness were based on relatively short time spans where nudges were new & novel: The novelty has worn off.

2) A simple nudge can't help a complex problem. A college may nudge "You haven't registered yet! Don't forget to register for the next semester". That's an extremely frustrating message to receive when you're poor and can't pay next semester's bill, or some other roadblock.

3) It has been used to justify not scaling human resources for students, so any benefit is offset by lesser real human contact with advisors. People complain about administrative bloat at universities, but that doesn't apply to advising: I've seen caseloads rise from ~300/advisor to ~500/advisor. This is especially problematic for overcoming #2 above: Advisors can often help with complex issues that student's believe are insurmountable.

My observations on how to do it better:

Only use nudges for low-stakes issues, and even then choose carefully so students don't become numb to them. High-stakes issues need human outreach. With limited bandwidth by advisors to do this work, it needs triage: Even if it's high stakes, don't waste time reaching out personally to low-risk students. Determining risk requires a two-pronged approach:

1) A statistical model that uses historical data to identify students at risk of poor performance or attrition. A competent data analyst can build a reasonable model without having to go too far into advanced data mining. "Deep Learning" tends to be fairly useless here: There's not enough data. There's also a few good vendors out there that will perform more advanced risk modeling, partitioning a school's population into a dozen or more groups and building models for each of them. These aren't cheap, but I've seen it pay off when correctly paired with one-to-one human outreach initiatives. In a single year I saw it reduce attrition by 1%, not to mention academic performance increases, and that more than paid for the cost. I've also seen schools pay the invoice and expect things to magically change without aligning their resources to the risk analysis output and waste a lot of money.

2) A rule-base system of identifying students at risk. Things like a late payment; a good student getting their first D or F in a class; delaying registration for the next semester; requesting transcripts to be sent to another school; and many other factors.

Using the high risk population identified in #1 and #2, that is where you focus your one-to-one human outreach efforts.
I’ve been noticing that 99% of the time when an article mentions the age of an individual, it’s usually a clickbait bullshit appeal to emotion/cocktail of other logical fallacies waiting to be gobbled up by unquestioning ninnies.
Most image processing has to do with imitating full frame sensors (better low light photography, DOF, etc.) So I'm not sure if full frame/APSC/Med-format cameras need the same image processing that camera phones have. Also, most people who use the bigger sensor cameras are probably pros. Most of them would prefer a "blank slate" and use RAWs.
What was the scenario?
Influenza basically disappeared from the US this past flu season. How do you account for that? I mean, CDC reports 2,038 influenza cases 2020-21 season vs 38 MILLION 2019-20 season. That's less than 1% of the usual load.

I'll also remind you that "data" is not the plural of "anecdote". In a large enough sample virtually everything comes up true.

There's also things that are true in bulk that aren't true in small samples. Oceans have tides. Glasses of water do not.

Meh, I want notifications on for whatsapp but I definitely don't want them on news sites. This is the wrong way to go about this IMO. Just a default, should definitely be overridable.
I've also had this "shock" with lenses much closer in generation.

I had a Canon 40D a while ago, and at first I was using a 17-40/4. I absolutely loved the colors I would get. Gradients would have a certain "creaminess" to them.

Then I figured I'd change it for a 17-55/2.8, to get some extra light at night. That was pretty much when I stopped going out taking pictures altogether. I just wasn't getting the pictures I wanted anymore. Everything looked just... weird and unsatisfactory. I then sold everything a when I realized I hadn't touched the camera in a year.

A few years later I got to do a similar comparison again, between the Olympus 17/1.8 and the Panasonic 20/1.7 on a Pen-F. The panny was OK, sharp, etc. But there was just something missing that the oly had. A kind of delicate rendering of gradients that just appealed to me.

This was when I realized what had happened with the Canon change earlier. I had believed that I had just lost interest in photography or that for some reason I just "didn't have it" anymore. I had never thought that a lens that was rated better in practically every aspect would actually be so uninspiring to me.
I'm not sure what you're saying exactly?

Many people from the community contribute freely to the FF codebase, and the Firefox project also employs paid engineers to work on the codebase. Funding to pay those engineers comes from Google. Donations to Mozilla do not go toward paying those engineers.

I think it would be great if individuals who aren't in a position to write code for FF could contribute donations to a fund that pays FF engineers.

>Remember when the Monsanto lobbyist/scientist said that their glyphosate pesticide Roundup is so safe you can drink it? To his surprise, he was offered a glass of it, and refused it, saying "I'm not stupid", and "I'm not an idiot", while insisting it's harmless to humans:

This is such a strange call-out. Yes, it's safe for humans, but who in their right mind would voluntarily drink it? "I'm not stupid", and "I'm not an idiot" are among the most reasonable replies in this instance.
> DPReview largely seems to write for the crowd that doesn't even care about the art aspect and just wants validation that they have better photo gear than others.

DPReview, FStoppers, PetaPixel, and back in before the web the Popular Photography and Modern Photography magazines. There's a big market for prosumer gear that costs a lot, has ideal technical specs, and hangs around the owner's neck like a prize. Of course these outlets, and the magazines before them, get almost all their money from advertisers, and run lots of review articles (totally objective of course /s) and are of almost zero interest to anyone working in the industry.

Great photographs can be taken with any camera.
That’s key, people are spending more on mobile phones now than they were a decade ago. The benefit they get is difficult to quantify on an individual basis, certainly the difference between a phone from 5 years ago have very little difference than one from today, better camera perhaps, but how many people who bought a separate camera in 2016 don’t bother now.
Alpine is indeed a fantastic experience for many use cases. But for me, it falls just short of being totally usable as a desktop/laptop OS because of the lack of package support for important things that require glibc. I'd love if I could use musl, truly, but there are a few things that just won't work and I need them daily. And every time I've tried using flatpak to fill in the gaps, I've been disappointed by broken installs or packages that just didn't work once installed.

As much as I hate to say it, I'd take a glibc flavor of Alpine as a daily driver in a heartbeat.
Wow, didn't know about this case.
Great camera. Don't discount the 3rd party E-mount lens makers, such as Samyang.

If you are unsure what to get next, I suggest looking at this list of every E-mount full-frame lens:

Excellent post. Thanks for sharing.
The main motivation is that the conventional approaches to data processing are based on manipulating mathematical sets for all kinds of use cases: we produce a new set if we want to calculate a new attribute, we produce a new set if want to match data from different tables, we get a new set if we aggregate data. Yet, we actually do not need to produce new sets (table, collections etc.) in many cases - it is enough to add a new column to an existing set. Here are more details about the motivation:

https://prosto.readthedocs.io/en/latest/text/why.html

Column is an implementation of a function (similarly to how table is an implementations of a set). Theoretically, this approach leads to a data model based on two core elements: mathematical functions (new) and mathematical sets (old).

This approach was implemented in Prosto which is a data processing toolkit radically changing how data is processed by heavily relying on functions and operations with functions - an alternative to map-reduce and join-groupby.

> The problem with this is timeline. If the donations naturaly outpaced Google's funding that'd be great, but it seems unlikely. On the other hand, if the stability of Google's funding came into question, how long would it take to ramp up alternative income sources? This isn't something that could be done overnight: it needs to be called out and contingencies considered early (now).

I don't disagree, but I also don't think this discussion is related to whether or not folks should be donating to Mozilla right now. My giving them a donation doesn't restrict them exploring other funding options, which they do seem to be doing, with Pocket and their VPN services and the like.

> Good alternatives to Firefox are much rarer

Right. So my thinking is: suppose Google funding dries up some day. From there we have two possible universes: Mozilla looks at their incomes and sees 80% of the missing funding is coming from donations. Or they see 10% is coming from donations. In the first case, they could scale down their non-core features and continue Firefox development on that donations revenue. In the second case, they would have to find some alternative income stream, which is difficult and full of uncertainty, or shut down and Firefox dies. Personally I favor the first universe, where Firefox is funded through voluntary donations. So I donate to make the first universe more likely. And there's no downside to me donating now, since it's totally cool with me if they use my money to fund their non-Firefox work in the meantime.

>No. The children of people in the top 1% are not predestined to be genetically superior. They are not some sort of ruling race. They are just people who happened to have been born to rich people.

You act as if parents just paid some money and people could score anything they want on standarized tests.

It requires shitton of effort to score top 1%.

I knew people who if could, then would buy themselves $top_score easily, but on standarized tests they didnt/barely passed.
None of the technologies you name had that big of a negative effect on society while they were maturing.

We are a decade in with cryptocoins and 98% of the things that cryptocoins have currently accomplished are a net loss for society. A net loss of which we are currently already "paying" for; Ransomware, waste of energy, people getting scammed with pump and dumps, etc.
Of course, it's almost certainly a drop in the bucket and a welcome distraction for those who profit by polluting on an industrial scale. Sort of like the extreme reaction to plastic straws--single-use plastics are certainly bad, but spending our political will on straws in particular yields very little return.

At the low noise levels that you get with high ISO on a D750 you really don't need stabilization w/ an f/1.8 50mm. Turn on auto-ISO and cap it it ISO 6400 or 3200. Even in low light you'll get reasonable shutter speeds at f/4.
Alpine has started doing point releases to help address some of these pains. However, as with most things it is usually best to have a testing strategy in place before doing upgrades.
I mean roughly each of those points doesn’t apply to every major crypto. But also no, I’m properly invested. You get to escape government stupidity into the open arms of criminals and scammers. Out of the frying pan and into the fire so to say [1]

If they were truly phishing it would be a great ploy, but here’s it’s just cruel. If someone is motivated enough to do the social engineering, they will be able to get a click. You will need something like proofpoint (not foolproof) if you allow links in your emails. If your company is large and ever fluctuating, to make everyone on your network a phishing expert is an insurmountable task.
I love it! What's the stack?
Alpine can load an overlay tarball (apkovl.tar.gz) on boot, of which it may contain a script to bootstrap a system (e.g., /etc/local.d/00_bootstrap.start) or an /etc/apk/world file that indicate a package to install on boot. The requirement is to be able to put a file named hostname.apkovl.tar.gz in one of the mounted disk(s) (can also be placed in the same disk as the boot disk itself). [1][2]

SumUp | Technical Lead | ONSITE or REMOTE (Boulder, CO)
SumUp is a fintech company focused on empowering small businesses. We're primarily focused on enabling merchants to accept payments, and we build a number of tools including POS devices (similar to Square). As a company we've primarily operated in European markets and Brazil, but we're hiring in the US to build out our Global Expansion team which will be responsible for establishing new markets including the United States.

We're looking for experienced engineers with a history of technical leadership on big projects. We use tools like Elixir, Ruby, Golang, (among others) to work on a myriad of technical projects related to establishing new markets.

We're especially interested in engineers who have experience with hardware certification and payments infrastructure, and those who have experience working on open source projects.

Send me an email at austin.tindle@sumup.com and mention hackernews if you're interested.
I think that may be the missing link here. It's probably from German beschließen, which would have been translated part by part as besluiten in Dutch, but in this case they took over the German word with the t -> ss high German consonant shift.
I definitely agree with your general view, it is my opinion too.

But then... that doesn’t help someone now who is very talented, able, hard working, but was overlooked for promotions because of gender or race. And part of breaking the pattern of white men promoting white men for the top jobs is mixing it up a bit. The country has the right to get the best experts for the top jobs, but also people have the right for an equal chance to get that job.

I won’t pretend I have the answer, but I’m less pragmatic about it than I used to be.
No, if I took more time off to “pursue hobbies and enjoy life” I bet I’d just end up watching more TV too. I doubt I’m above the ingrained temptations that make the leisure industry go round.

Estimize and ExtractAlpha Are Merging
Isn't the statement that "there exists a program for each system such that arbitrary code execution is possible" a tautology?

Aren't you basically saying "Executing arbitrary code can allow executing arbitrary code"?
That's the work that leadership should assisting in -- enabling devs to recognize and move into situations where pairing is beneficial, and giving them the scheduling tools and methods to do it successfully. The best a company should be doing is helping devs to recognize the benefits, and when they are activated for a task, and importantly, when they don't exist for other tasks. It's still such a new area, business wise, that I think it's often done very wrong.
"... the language issues with some not so well worked out features should be fixed, instead of trying to please everyone."

This. For average programmers like myself, latest and fanciest language features are of little value. C++ and (unfortunately) D are in the same quest: to incorporate every programing language paradigm available, the extra complexity be damned. In the specific case of D, I'd rather have a good assortment of native D libraries than more bells and whistles added to the language.
Very cool. But I can’t help thinking they would be siting ducks if there was armed resistance on that vessel...
I understand that. I worded it poorly. But it was still part of a general space that was interested in Microsoft alternatives.

The way out of this is called unit testing. Code like this is just over engineered crap without it. Most of the effort is writing good tests. Show me the test that tells me in a concise way what this is actually supposed to do.

Mostly purity in this context boils down to weird combinations of premature optimization or complete disregard for that. Mostly it doesn't matter of course since code like this runs on trivial amounts of data so giving the garbage collector a little more work with silly stream objects, boxing/unboxing, etc. does not matter. Code like this does not matter, at all. Unless it's wrong. Hence the need for tests. Without tests it's just more likely to end up in tears. With tests, it doesn't really matter what the code looks like as long as the tests pass. If it's convoluted without tests, it's a problem waiting to happen.
It’s certainly possible to make a living off of YouTube/Twitch streaming but you certainly won’t “make it”. It’s basically the same as asking if you can make a living off of being a musician or a painter. The competition is so fierce and the market is so saturated that it will take a miracle to get noticed and be popular. Don’t get me wrong, if it’s something you enjoy doing then give it a shot. But realize just how much of a longshot it will be and be prepared to move on to something else.

collecting stories that have (year) on them once may have been a nice way to surface archive essays and interesting pieces. These kinds of posts are submitted daily now and it's getting annoying/ridiculous when things are submitted less than a year apart, sometimes even monthly!

Old articles that have been discussed heavily, improved upon, circumstances changed, technology evolution especially, are mostly lame to revisit on a site that still should weigh heavily towards current events/news developments.

I'm just getting tired of sifting thru resurfaced old posts from 2016 or whatever
This strikes me as true.

I wouldnt say the camera companies did not see this coming. They did and chose to not do anything about it. I shoot videos with some pretty low end DSLR cameras and they are often lacking the feautures of any modern flagship phone. It's a joke. We once used a whole Iphone shooting at 120fps and made some plain scenes look amazing in post. A revelation since most pro videographers pooh pooh phone cameras without realizing that they are growing with alarming speed.
