What is the definition of scientist or engineer?

A lot of people with science or engineering degrees go on to careers which don't make use of what they have learned in their degree (for example finance), and instead use the degree on the CV as an indicator of 'probably a smart person'.

In countries without that effect, people might not see the need to get an engineering degree to get those same jobs, and instead prove they are a great candidate in another way.
That whole discussion would not exist if java had a convenience syntax for rethrowing checked exceptions wrapped in a RuntimeException, in less than the customary four extra lines.

Some kind of call-site use of the throws keyword perhaps?

byte[] bytes = "Example".getBytes("UTF-8") throws RuntimeException;

I can't really think of a reasonable use case for anything other than RuntimeException, but in the old days, some people would surely have loved to rethrow wrapped as MyCompanyException.

A high school I attended had a fairly novel system that's not too far off from this. People in the program I was in would get to school at 8 and leave at 12, with a good deal of variety in what classes they chose to attend. And classes were run on a college schedule with two sets of classes - short MWF classes and longer TTh classes.

The overall affect of this is that good students would end up receiving a more directed education and were in a much more desirable system with immense freedom to pursue their education and growth as they saw fit. But at the same time 'less good' students did extremely poorly. And I think in general there is going to be a strong connection between increasing freedom and increasing the polarization of results. In a way it's really an educational analog of the differences between capitalism and communism.

I'm sorry but I don't see how the two studies referenced in the article "vindicate" your complaints.

The study that is the main subject of the article found that a) the enteroendocrine cells of mice send signals to vagal neurons and b) in a petri dish, enteroendocrine cells form connections with vagal neurons.

Neither of the two points seem to be connected with migraines, specifically, and they remain the results of one study, in vitro and in an animal model.

It seems to me it's too early to feel vindicated about anything.

Later, this behavior appeared to be an artifact of intrusive laboratory observation. Whether the behavior is natural in the field or also the result of distractions caused by the human observer remains controversial.
It's fairly easy to get something like this with Java 8. I have my own set of wrapper functions that let me do something like:

"Although it is often supposed that octopi is the ‘correct’ plural of octopus, and it has been in use for longer than the usual Anglicized plural octopuses, it in fact originates as an error. Octopus is not a simple Latin word of the second declension, but a Latinized form of the Greek word oktopous, and its ‘correct’ plural would logically be octopodes."

I'm curious, and haven't seen it mentioned, how mdma affected the octopus's color-changing and signaling abilities. It causes human eyes to dilate, but octopuses don't use their eyes for color-changing (many are color-blind).

I don't know if there'd be a biochemical change that limited the octopus' ability to change color or a psychological change that changed the octopus's desired signaling. Could be both!

I sort of see the point of the article but I think talking about differences between pointers and integers obscures the real issue here: the problem as far as I can tell is just that offsetting a pointer more than one byte after the end of the object it points to is UB.

TFA argues that converting to integers first sidesteps the issue but I'm not convinced (although I'm not a C standard lawyer). Surely if you convert a pointer to an integer, add an offset that's greater than the size of the original object and then convert that to a pointer you trigger UB? How else could this be defined? You can't really expect the compiler to figure out what you're doing when you're casting "random" integers as pointers.

Also the article mentions Rust in its introduction but in Rust anything surrounding pointers (including pointer arithmetics) is unsafe so I don't think there's any conflict whatsoever here.
Just Enough Scala for Spark
To clarify, this is from the original Science article linked to by the article at the top of this post:

Thus, enteroendocrine cells are chemosensory cells that activate vagal sensory neurons via release of glutamate (see the figure). Kaelberer et al. hypothesize that synaptic transmission confers precise spatial and temporal information about gut contents. Such sensory feedback could allow neural control of rapid processes that modulate gut physiology, such as muscle contraction, whereas neuropeptides such as CCK are responsible for long-lasting behavioral outputs of gut stimulation, such as satiety (5, 6). A remaining issue is what behaviors or physiological processes rely on subsecond neural signaling from the gut.

It seems those gut-neurons (or whatever they are) serve to inform the brain of the gut's contents.

There is nothing there (or in the rest of that article) to suggest a connection between the gut and migraines.

For the record, I find it dangerous to feel "vindicated" about any personal dispute on the basis of any number of articles in the scientific press, especially so if they're in a field that you are not specialising in. It's very easy for your feelings to get in the way and push you towards all sorts of misunderstandings of what is claimed in those publications.
In 2009 I was applying to grad schools and was a complete nobody shmuck. I was walking through MIT on a grad student visit and we went past the offices of both Gil Strang and Sigurdur Helgason and I told the grad student guide that I just had to give it a try to say hello.

Not only did Gil Strang say hi, to some totally random nobody, but he invited me into his office, asked me about my undergrad studies (he even knew one of my undergrad professors well), and said a lot of nice and encouraging things about sticking with mathematics and finding a career. Siggy Helgason wasn’t in, unfortunately, but I remember Gil Strang referred to him as “the national hero of Iceland” and said I should say hi to him too since I was interested in differential geometry.

What a guy! So gracious with his time in a way that too few academics are (which ended up being part of why I quit a PhD program about 4 years after that talk with Gil Strang and started working instead).

Agreed that there are some benefits to having exceptions as part of the interface, but there are ergonomic challenges around being annoyed with a bunch of breaking changes in spots where you really don't want to be hassled with the details. I see it causing more problems than it solves. When people are forced to handle exceptions, they often handle them badly. IMO, an immediate program crash with a nice clear stack trace due to an unhandled exception is almost always preferable to a festering, difficult-to-trace (or even detect) bug due to an error condition that got swept under the carpet.

You're very likely to get some of the latter sneaking in with an interface change like the above. The person who made the change is going to be the one who gets stuck getting the code to compile. If they are faced with tens (maybe even hundreds) of compile errors, they're going to be forced to make a whole bunch of unplanned changes to a bunch of code they didn't write and might poorly understand even before they can get to the point of being able to start running the unit tests.
I don't think so - I think that the human may fail to find the correct label for the Elephant (although if they have some knowledge about Elephants they might), but the machine fails to see it - to identify it as a thing, and also it changes the labels it gives other things; so cats become dogs, mugs become books and so on. Humans are not prone to this.
The payload is such an interesting comparison that there is a word for it.

The wikipedia articles give 100,000 kg for the BFR and 140,000 kg for the Saturn V.

For hundreds of missions, the BFR strategy of refueling to leave orbit probably makes sense, but it's pretty clear which rocket puts more payload in a 90 mile orbit, a very direct comparison of launch capability.

And of course, BFR may exceed projections (or fail to meet them).
I'm not sure the comparison is that significant. We tend to omit two aspects when we deride price changes:

One is just inflation. No need to explain that. In 15 years at 3% annual inflation rates, the $500 becomes $780.

Second is that the product has changed, massively. The better comparison is to a flagship phone-only, which is $30. Or to compare the iPhone to a range of products, e.g. a phone, but also a television, a videocamera, photocamera, pocket-microphone, GPS tracker, mp3 player, navigation system, fitness tracker, and some kind of pocket computer that lets you browse the internet, read news, take notes etc. It's quite remarkably different from a phone, and we sort of have to thank Apple for this 'issue' in them calling it the iPhone and getting smartphones as a permanent product category. When really it's a computer first, phone second. Try selling an iPhone that can't do anything but make calls, then try selling an iPhone that has its call function disabled, the latter would outsell the former by a large margin.
So you could get a million dollars worth of phone for a few hundred. Bargain!
They are.

It's also not consistent in who starts first. I went to three school districts growing up: in two the elementary students started before the middle and high schoolers and in one the high school and middle school started first. It's pretty arbitrary who starts first.

You are tilting at windmills here. You can say "not the users problem" endlessly but unless you're about to quit your job and never work at a commercial business that uses digital advertising again, it's just random noise that goes nowhere near attempting to solve the problem.

Advertising, and the greater concept of marketing, is what powers the growth of practically every business on the planet. Two of the most valuable companies are advertising companies because this matters so much. These companies do care about risks but the real problem is lack of regulation which is completely unrelated to browser cookies, so in the lack of such rules we can look at technical alignment that can solve at least some of the problems in the meantime.

> I don't expect you to understand this if your salary currently depends on not understanding the harm created by the ad industry.

FYI, less tracking means more money for ad networks. It means you can never optimize results and will have to run more generic campaigns, which waste more money and are a worse experience for both advertisers and users. So while that statement sounds good, the reality is that people in this industry are the best to consult with on ways to improve it because they work in it every day.

> Until then, I suggest at least talking to the average person about what they think about having their activities tracked.

I've been in adtech over a decade and I'm the only person with a business/technical background who has spent time, effort and money to push ad regulation in the US. I've talked to countless people from ad networks to adblockers to senators to grandparents. I'm familiar with all the arguments and what I presented is a way to make forward progress.

95% of generative art is fridge art - beginner-level doodles by people who haven't taken the time to learn anything at all about art history, art techniques, composition, colour theory, physical art media, printing techniques and technologies, art-as-culture, or even just the history of digital graphics.

And implementing algorithms designed by someone else doesn't require any obvious imagination.

Luckily 5% (or so) of generative work is more interesting than this. But IMO there's a huge, huge gap between the quality and imagination of the work done by people who are talented and committed enough to work on generative art for years, and the people who knock out a few doodles in Processing (or Quil, or some other system) and feel terribly pleased with how creative they're being.

So no - it's not interesting art. It's an excuse to play with algorithms for people who enjoy playing with algorithms. This particular excuse makes graphics. But it's still a superficial excuse to play with toy code, not a form of insightful psychological or perceptual abstraction and/or original self-expression.

They aren't, because you have to use clunky verbose syntax (and try/catch blocks aren't expressions, which makes things worse). Also, there are several limitations on generics with exceptions that don't exist with regular values.

My point is that there's no reason to include special syntax/concepts for checked exceptions over just using values.
Oddly, a lot of popularly used images of the brain are of my brain. I gave a permissive CC license on a still from an MRI of my brain many years ago on Flickr.

The bigger publications sometimes think to obfuscate my name from the MRI itself, but most don't.
