Not an unreasonable expectation, if you’ve been paying attention to Apple’s pricing lately

They now sell an iPad, arguably better than any of the non-iPadOS competition, for $350.

The iPhone SE, one of the fastest smartphones on the market (only other iPhones are faster) starts at just $399.

They’ve aggressively been cutting prices, I believe, so that they can expand the reach of the services business. They’re cutting costs to expand their userbase.

I wouldn’t be surprised to see the return of the 12-inch MacBook at the $799 to $899 price point, now that they no longer have to pay Intel a premium for their chips.
Thanks for this comment! Universities are where the majority of scientific research is conducted today, and I hope that won’t go away anytime soon (severely restricting immigration and funding might change that). Many of the Professors I worked with considered teaching to be an obligation; they would rather spend their time on research (doesn’t mean they don’t teach well, some do, others don’t). As long as we continue to find research Universities themselves won’t be going anywhere.
Have you written a lot of concurrent code in rust? Did your experience doing so convince you that it's something you should "fear" doing?
For all the talk of "defund the police," state and local police departments don't actually have the budget to hire someone who knows which way is up in choosing third-party contractors for online services (much less the budget to contract with services that aren't lowest-bidder).

Actually, this is yet another example of why defunding the police is so important---they don't even spend the budget they have well.

I am wondering about your outtakes and thoughts around having PDFs on a company's website. Are those unprofessional?
The problem is that Hall-effect thrusters provide basically no thrust.

Most Hall-effect thrusters provide millinewtons of thrust, with the best lab model producing 5.4N and the planned AEPS motor producing a theoretical max of 2.356N.

A single Merlin 1D motor produces 690kN of thrust at sea level. You would need over 290,000 AEPS engines to match one Merlin 1D engine. At 40kW per engine, this would use 11.7 gigawatts to run, so you’d also have to add in the weight for a dozen or so nuclear power plants.

Keep in mind that the falcon 9 uses nine Merlin 1D motors for the first stage.
There are already implementations out there in Python. [1]

The point of that project is to be a very fast alternative to those implementations while being more accessible than a C++ implementation.

Yeah, as someone that has reviewed thousands of things in the review queues: There's SO. MUCH. TRASH.

A forum is for discussion.

The early adopters of Stack Overflow saw it as something closer to Wikipedia. A source of technical documentation. This still exists in the closest thing to a mission statement that one can find: https://stackoverflow.com/tour

> This site is all about getting answers. It's not a discussion forum. There's no chit-chat.

One similarly doesn't see "hello" or "thank you" in encyclopedias or technical documentation.

There are places for human interaction (chat in particular) - but in a question, answer, or comments it isn't useful.

Consider that the summary part of a question that shows up shows the first line or so of the text.

> Hello. I am a new user with Java but I know C#. I have searched everywhere but I cannot ...

Compared to:

> When using Java, I am trying to use a stream to select some data and write it out as a file ...

For comments, this has been looked at in the past - https://meta.stackexchange.com/questions/204402/hide-trivial... and https://meta.stackexchange.com/questions/210265/how-can-we-m...

Having comments - especially trivial comments - means that voting doesn't happen as much and that then impacts the ability to get a signal to curate on.

Normally I'm content to follow the data where it leads, but I opened this with trepidation lest it give me a reason not to enjoy my morning coffee. Fortunately it confirms my pre-existing biases.

I find I can never just have one cup, so I make a 50% decaf mix and have 3-4 cups spaced out over as many hours. Not only does this give a smooth and constant hit of caffeine, but it suppresses my appetite as well and I easily power right through from 5:30 until midday lunch. These are by far the most productive hours of my day.
Maybe "it didn't matter if it didn't work" is a better was of putting it. The UK's COVID-19 repsonse has been PR driven - a constant stream of headlines to fight public opinion fires, with a sprinkle of corruption thrown in where possible (there will be plenty more of this to find when the dust settles).

None of this sounds like public health driven leadership to me:

- Hancock's test target was miraculously hit - bending his own rules to boost the figures (and wasting thousands of testing kits in the process)

- Dido Harding trumpeted as a tech heavyweight brought in to deliver a futuristic solution - despite famously claiming after her company's massive data breach "It wasn't encrypted, nor are you legally required to encrypt it. We have complied with all of our legal obligations in terms of storing of financial information.", and sitting on the board of the Cheltenham Festival which opened it's doors to 260,000 people just days before lockdown.

- Dominic Cummings publicly supported by all senior government politicians for breaking the public health guidelines they created

- Rebranding the coronavirus messaging without consulting the behaviourhal psychologists on the governement's own SAGE committee - resulting in unaccessible unactionable nonsense

etc. etc.

This is like when the food vendor at my old work raised the prices on soda. They claimed it was a health initiative, but they also increased the prices on diet soda and even bottled water.
We've all been there. You do the loop and the feedback you get from the recruiter/hiring manager is binary Yes || No. And when it's a No, you get one of the two types of feedback:

1) Sorry, you didn't get it
2) None

This has to stop, and I'm trying to solve this problem. I stood up InterviewAt at the beginning of the COVID pandemic as a way to help folks who were being displaced. The service is up and running, and I'm still doing the mock interview sessions free of charge.

I already knew that there is no great feedback mechanism and I wanted to improve on that, but I also discovered there is no great resource for learning from actual interviews for professional roles. How many of you have actually sat in on a VP Engineering interview? Or seen a great Sr PM interview? These are real interviews for people preparing for interviews for real roles.

I've also started a YouTube channel where I will be posting interview segments with analysis and assessment. I've been an exec at MSFT, AMZN, and ORCL, and have run my own startups with exits. I'm doing this as a new company I've started this year because I feel it's really important so that we can all learn and get better from the feedback that you wish you had received when you looped for a role.

Feedback is welcomed, but if you have an upcoming interview or what to get real, executive level feedback on how you show up in an interview, please give us a look.

Racism is anti-logic. Full stop. It's an ideology that reinforces itself only through the continued rejection of information. Racism is used extensively to study the backfire effect in psychology.

The only way for such an absurd system of beliefs to exist is to either rely exclusively on morally bankrupt individuals, or to heavily lean on confirmation bias and reject any anti-racist ideas.

The combination of Google + SO always seemed too good to me compared to most everything else on the Internet. It just works really well. I think this is the closest thing we have to mind reading at least when it comes to programming problems. It'd be shame for it to go away be it SO doing more and more dumb shit like adding touchy feely bs like "thank you" mechanism or Google being hit by antitrust into oblivion.
Likely, I've unfortunately had the displeasure of being a victim of that, probably an off-the-shelf scanner that exploited a Wordpress weakness.

That said, I do think PHP software should be distributed in such a way that the files are both locked for editing by the PHP process itself, and verified regularly. I've been using XenForo on my website for a while and it's giving me e-mail warnings that a file has changed (I did a customization), so it does exist.

But yeah, that particular category of error can be mitigated via config; disallow PHP execution in an upload folder, disallow PHP to add or edit files in the application folder, etc.

It's definitely common in Denmark. France has crème de cassis[0] and produces 16 million litres annually of the stuff.

Top universities can still keep their most valuable asset: a piece of paper with their name on it, scarce. They likely will and be fine. Those degrees will still open many doors.

The lower tier universities that charged tens of thousands of dollars to offer a minor leg up for your resume among the pile of resumes when applying for a job though are in big trouble. Ultimately colleges will more clearly shift their value proposition from "here is where you learn key material" to "here is where you learn to be an adult" and survive I think. Most kids out of high school are idiots and need some sort of structure to latch onto as they leave adolescence / the nest.

There is an (admittedly controversial) idea within the medical community of Specialist induced demand. I have heard it quoted to me that studies have shown that when a medical specialist moves into an area that they then generate more demand for related procedures. Personally I am not in the medical profession but am wondering if anyone more knowledgeable can speak to this. Specially what percentage of procedures could be considered in this category or is this just ridiculous?

As a personal example, I received a nose surgery once that opened my nasal area so I could breathe better but it only lasted a few months and after that it seems to have reverted so it appears to be an unnecessary procedure at the end of the day. I have just decided to live with the difficulty as the recovery was awful.

I agree. Debating racists does not necessarily mean giving them a platform though. They may already have one. The current US President is well regarded as a racist but he has a platform regardless of his racism. This is true of others as well; it’s not just KKK members who are racists, it can be anyone, especially anyone wielding power via institutions.
For those like me drawn in by the bad headline, FYI the article itself uses the obviously more correct analogy of live entertainment in the streaming age. (TBH I didn't read it, just skimmed to see if they were really going to use only the bad analogy)
Right now you have the two political parties and virtually all the S&P 500 corporations, all the universities, and most of the media (including social media) actively supporting BLM and being against "systemic racism".

I know that things aren't that simple, but where is that "systematic racism" actually coming from, then? It can't be from the law, since the civil rights era has removed any legal discrimination.

And it can't be just coming from Fox News, 4chan and the odd corporation that doesn't tweet BLM stuff either.
Apparently, many such coffee studies are sponsored by firms with an interest in publicizing coffee's benefits. It doesn't mean the science necessarily isn't good. Although, consider the opportunity cost: we could instead be researching many other things that don't carry as high a cost as coffee (in terms of production labor, refining, and transportation), and may commute even greater benefits. Of course, we shouldn't expect big corporations to sponsor that kind of research, because it's not in their interest.

It is decidedly in the interest of coffee conglomerates to demonstrate that coffee is good for society, because it justifies the great fiscal and human expenses they go to, to bring fresh coffee to your breakfast table. Not passing judgement either way, it's just an interesting lens to consider.

There was a nice article in the new yorker a couple months ago on the subject of society's shifting moods towards coffee, and how it's materialized in the literature and science. https://www.newyorker.com/magazine/2020/04/27/the-war-on-cof.... One of the reviewed books: https://www.amazon.com/Coffeeland-Mans-Empire-Making-Favorit....

Edit: oh boy. I misread the parent comment. I thought they had declared a conflict of interest. Sorry. I didn't intend for my comment to read as a corporate-research apologia.
Your specific experience is great, and I'm glad for you.

The point here, however, is what University is for all people, not just for individual cases like yours where things align nicely, and where maybe your own character and personality (and some of your professors and class mates) helped you get a meaningful experience out of it.

My personal opinion is that the article is mostly right about what doesn't make sense for Universities in 2020. Many things are wrong, including providing access to it for ALL valuable students irrespective of income or wealth.
If the average family size is three, then to account for the "or a family member's health" would mean something on the order of 10 million Americans adversely affected.
> Carol Greider’s 2009 Nobel Prize was based on work inspired by informal phone calls and emails from Bret

Bret is quick to point out that Dr. Greider's Nobel prize is well deserved and for related, but earlier work. The contention is over later work.

Their conversation did inspire these findings about lab mice telomeres. But Dr. Greider's lab decided to keep the information "in house". This means that instead of publishing the source of the information, they can use their knowledge to start predicting other results, and publish a full stream of paper first. This is at 1:23:50.
maybe so, but there is a certain level of self-discipline and privilege needed to be able to study just from books. Lots of people on CS and other courses want friendly exposure to new ideas, not a recommendation of a list of text books
I think the point was that many people talk breathlessly about Lisp but are often quite hand-wavey about specifics. When this concern has come up before I've seen them dismissed with comments along the lines of "if you have to ask you won't get it" or "just read SICP".

I've written and read a bunch of lisp and I'm slowly working my way through SICP at a leisurely pace, but I totally understand what these OP means. Some talk about lisp as something magical (it appears on xkcd as a sort of "god's programming language" - https://xkcd.com/224) yet often seem cagey about actually sharing exactly why they think so. A great example of what I mean is this pretty famous essay by pg: http://www.paulgraham.com/avg.html.

In fact he says "Lisp is so great not because of some magic quality visible only to devotees, but because it is simply the most powerful language available" - which seems to dispel the "magic" bit ... but then throws out the tantalising "most powerful language" without (in my opinion) giving a compelling argument. He mentions how lisp macros are more powerful than those in C and does say "Lisp code is made out of Lisp data objects" and a few other bits and pieces about how it was higher-level than other popular languages at the time (the mid-1990s). It certainly made me curious to explore the language, but definitely left me with unanswered questions.

My opinion is that this phenomenon is a result of a number of things, including:

1. some people went through a transformative experience through learning lisp, and are deliberately vague to entice others into exploring it without ruining some of the fun of self-discovery

2. some people had the same, but think that it's enough to declare these things and don't care if you believe them or not

3. some people parrot what they have read some smart folks say and simply can't formulate a good explanation even if they wanted to
Just to drop you down a peg, I can invent a sci-fi scenario in which my point is made too: An advanced race views how we treat animals beneath us and decide to reciprocate as we are as far beneath them as mice are to us.
Sure, but htmx is small (~1.7K loc[1]), written mostly by one guy part time and, while not perfect, advances HTML significantly as a hypermedia. That something like this hasn't been discussed in a significant, public manner by the w3c in over a decade[2] indicates to me there is either a lack of understanding or of interest in advancing HTML as a hypermedia.

I readily admit I may be missing something.

In my opinion to improve the reputation of this research-branch we should start both moving conflict of interests in the abstract of the publication and dedicate mesh-keys to conflict of interests in public medical databases. Much crap would be more easily flagged and moved on with.
> So concluding that a bunch of individual genes have small effects is actually less supported than the similar claim that a bunch of individual societal/environmental factors have impact.

What an absurd claim! This is specifically the hypothesis that the last several decades of twin studies is designed to test. You are either ignorant of this body of research or you are being disingenuous. We can distinguish between these two cases because adopted twins and siblings have highly correlated genetic factors and weakly correlated environmental factors.

I notice that you keep avoiding the absurd improbability of environmental factors mediating bulk racial differences given the magnitude of population-level differences and the relatively small fraction of variance attributable to environment - but you seem desperate not to acknowledge the latter.
How to add automated code templates for react components
I've been confused by this for a while as well. The answer seems to be there's not such thing as a "true" cup of coffee. It pretty much just means whatever the respondent considers a cup.

(In contrast to studies on alcohol consumption, where researchers have standardized units. And even on surveys will make sure to clarify with respondents so they get responses in normalized units.)
Feels like that sometimes, doesn't it? Then you find an employer in said technical profession who understands how their field has become inefficient at sourcing new employees and they seize on the opportunity to open the gate and let 'em in, thus creating a competitive advantage in the hiring pipeline and diversity in culture.

The real tragedy is when all the others who can't/won't/don't open the gate cry whine and complain about not being able to find talent. Sometimes, when they are really pathetic, they have the gall to go to their local economic development agent with their hands out for a subsidy for hiring assistance.

So those who adapt to the times end up paying taxes into a system that, in turn, gives that money (in part) those who don't. Perverse much?
Yea, cherry picking, me. Note that the rebuttal does not refute Pall's biomechanical thories, or say that there are no non-thermal effects, but that we need more thorough research, and that this research is not being funded. The precautionary principal (ignored in the USA, it seems), would indicate that we should be cautious and not quick to dismiss.
Yes, those are good questions.

It's more common in the UK than elsewhere, but I grew up with blackcurrant as one of the most common types of squash/cordial in Norway as well, with a wide range of brands - to extent that blackcurrant is the expected taste of red squash if nothing else is specified. I know it is also widespread in Denmark as well.

It may well be uncommon in parts of Europe too, but not to the extent of particularly the US where most states banned it for nearly a century because it contributed as a reservoir to diseases that threatened white pine, which made it uncommon enough that most Americans have never tasted it.
