In my engineering education my favorite and most productive learning came from the professor who assigned graded homework and provided fully worked solutions to the given problems before when the problems were assigned.

You had to do them, you were completely able to just copy the solution, and when you were working on something you got immediate feedback as to whether you were doing it well. If you wanted to learn you could, if you didn’t you wouldn’t. The lack of a week or two of lag between solving a problem and figuring out if you had done it correctly really made a difference.

>and 2 on an openSUSE tubleweed system using BTRFS as root.

How long ago was that? and have you been using other fully checksummed filesystems (like ZFS) on that hardware since then? I'm asking because if you're using btrfs without any raid features (or with simple RAID modes like 1/0) for the past several years and it breaks, if you dig deep enough into the problem, often the hardware is found to be at fault.

And ext4 or xfs either don't find corruption at all (if it's data corruption), or have better error recovery if the FS's own metadata got trashed (which is a strong argument in favor of them, I agree, but I wouldn't trust such a filesystem anyway and would restore from backups right away).

Edit: it's a strong argument for storing data on them which is checksummed by some higher component in your software stack, like the database. Otherwise, you're just asking for silent data bitrot.
The fact that this requires in-app volume controls, or that an app can block other audio sources, feels like a limitation of the system.
> For water consumption, that same ton of lithium takes 170 cubic meters, which is about 2 person-months of urban Chilean water consumption.

m3 of water is a nonsense metric. Water is abundant in some places, and in those places it might as well be free. In other places it is highly scarce. Furthermore water is not consumed it's just borrowed for a while. So really you need to look at it more qualitatively, tell a story of the consequences of the water use.
Adding on, I've been using ZFS as my root partition on Arch with the latest kernel and zfs-dkms and have never had a problem.
Good breakthrough but video on page was troubling to me. The plastic surgery made me feel uncomfortable. Seeing that face way too often.
You shouldn't be so sanguine about that, because the metadata is often 80% of what your adversaries are looking for, especially if your adversaries are government-backed.
I'm far more risk tolerant than that. "Safe" is a watchword for me that reflexively makes me doubt the argument. I have no problem with the idea of disclaimers, ratings, whatever, but give adults a choice to engage the open information dream that the Internet was/is.

At least when the government tries to police something we can grab onto it, debate it as a matter of policy, and there's a process to change that policy. With private companies trying to do the work of the government (if that really is the case, and whatever their reasons - fear of formal regulation, etc), it's far harder to manage. I'd rather have a clear conversation about the government's ability to censor speech than have a few oligarchs working as shadow censors on behalf of the government.
Golang: A Beautiful Mess
For modern audiences, I would recommend https://en.m.wikipedia.org/wiki/Metropolis_(novel) over the film adaption. The film is amazing for it’s time. But, is... difficult to appreciate today. The book however, has some of the most intense imagery I’ve ever read. I had to put it down between pages to give my mind a bit of time to process each scene.

An important bit of context for the book is that it was written by a woman who moved from an agrarian village in Germany —where nothing had changed for hundreds of years— to height-of-the-Industrial-Revolution New York. It was quite a shock. And, imagine the book is from her extrapolations.

A fun bit is that it was written long before the invention of computers. So, this vision of a technologically advanced society has no concept of computerization and substitutes mind-numbing, body-crushing proletariat labor as the means of automation.
It appears to me that the problem with reasoning by analogy is that we often focus on how x is analogous to y, but skip over the part where we think about how x is not like y. Without intentionally making that step, we bring a lot of unwanted assumptions into our understanding of x because we haven't focused on the ways it is different.

I'm curious to hear more about what distinguishes learning to program in a "purpose-first programming" approach.

This sounds really similar to constructionist learning ideas that Seymour Papert espoused. Remember Logo? That's Seymour Papert. His paper "What's the big idea? Toward a pedagogy of idea power" is a good place to start that straddles the line between concrete and conceptual. Paper link: http://worrydream.com/refs/Papert%20-%20Whats%20the%20Big%20...

When I was reading it in the spring I was skeptical for exactly those reasons, but it quickly became clear with even the smallest bit of research that it was well accepted the Vitamin D deficiency was linked with worsened effects from common viruses and that the vast majority of people in my region were deficient.

They do now. But for a long time they didn't (I think). Or maybe they always did but were unreasonably expensive.
And much closer to real life. Nobody will ding you on the job if you need to look up the implementation of an algorithm or data structure. Knowing which algorithm or data structure is appropriate is far more important.
> What's that reason?

Apple’s efficiency is based on a very wide and deep core that operates at a somewhat lower clock speed. Frequent branches and latency for memory operations can make it difficult to keep a wide core fully utilized. Moreover, wider cores generally cannot clock as high. That’s why Intel and AMD have chosen to pursue narrower cores that can clock near 5 GHz.

The maximum ILP that can be extracted from code can be increased with better branch prediction accuracy, larger out of order window size, and more accurate memory disambiguation: http://www.cse.uaa.alaska.edu/~afkjm/cs448/handouts/ILP-limi.... The M1 appears to have made significant advances in all three areas, in order for it to be able to keep such a wide core utilized.
"tweet unavailable" is a different error from the "This is not available to you" message. Got that message earlier today when I tried to open a different linked tweet. Changing to nitter fixed it for me.
Honest question here, is the mechanism in those mRNA treatments totally different? I can't imagine there is a 'spike protein' you can focus on with cancer - but perhaps I am totally wrong.
Perhaps "purpose-first programming education" would be a better way to phrase it. Which, yes, is incredibly valuable. I recently adapted my learning process from tutorials to taking a problem I already know how to solve with a different language or tool and solving it with something new. It frees the mind space required to define a problem space, figure out process, etc., and allows me to focus on learning how to do that thing with this tool. Then if I'm attempting something I don't really understand, I'll use tools I understand well.
Although I agree with the core of your argument, I think this position is a little reductionist. Yes, you really do need to understand what's going on under the hood (though, choose your hood). But you're also almost-but-not-explicitly saying that analogies and metaphors are not valuable tools for engineering. I really strongly disagree with that.

As one example, I find analogies downright necessary when working with a complex domain -- you have to find ways to speak domainese in the software world, or speak programese in the domain world, and analogies are precisely the tool for that job. It's easy to think that domain concepts should have a 1-1 representation in the software world, but in my experience, that's neither true nor productive. You do need to understand (and document for others!) the mappings between those concepts, but they shouldn't be so rigid.

On a related note, I'm reminded of Terence Tao's thoughts on rigor in mathematics [0]. He divides expertice into pre-rigor, rigor, and post-rigor phases. It's necessary to understand the rigorous elements, but those (a) build on intuititons built up over time in the pre-rigor phase and (b) support expert, formalizable intuitions in the post-rigor phase.

> So... if you want to become a decent software engineer, start with learning digital electronics and assembly.

I disagree here too, though less strongly. I think it's important to have approximate intuitions that can be refined, rather than trying to manufacture a precise understanding out of nothing. Those intuitions can be built up by trying, failing, and accomplishing projects that you're motivated by. Even if Djikstra is right about "radical novelty", you obtain a certain amount of mechanical sympathy just by fighting with the computer and learning its needs.

The "Purpose-First Programming" research [1] that this article's submitter also submitted today seems relevant.

> Isn't Africa doing surprisingly well?

Yeah, so this is a notable bit of nuance. Black people in Africa likely tend to get a bit more sun exposure compared to Black people in northern territories e.g. Europe, US, etc., so it wouldn't surprise me if Vitamin D deficiencies among Black people in the US and Europe are much more prevalent.

Wouldn't surprise me if the same is true in southern India or other territories where melanin (genetic or otherwise) tracks with sun exposure.
I believe you misunderstand how the process of learning occurs. If you really want to deeply understand something, it's a whole process of connecting up existing facts and schemas in your brain. That happens more smoothly over time by processes like seeing metaphors. A good teaching metaphor always involves a description of how the metaphor fails. Learning from metaphors is not a weakness, nor is it the only plank to build a house of knowledge on. Eventually, you will need to understand the mechanics too, but there's nothing wrong with starting with metaphor, or examples, or visualizations, or interactive simulations, or any other teaching scaffold.

Also, don't gatekeep the field, unless you have a citation that proves that modern teaching techniques have really led to a decrease in quality of software engineers. I really doubt you have any concrete measure you can point to that won't be anecdotal, but if you have one I am interested in hearing why you think you can strongly believe that folks have gotten wore over time because we got better at teaching.
If there are, I'd love to know if this particular vaccine obtained them in such a way.

I think the heart thing reflects a somewhat serf-like idea. That you were born into a class, and that was your role for the rest of your life. If that is your frame of mind, then the conclusion of the movie makes perfect sense. The most honourable thing the ruling class can do in such a world is to give their workers some free time.

That said, I don't know what Lang's political views were, and Serfdom has been abolished in Germany for about 100 years when the movie was made.

I actually like like the movie quite a bit, but I've always been disappointed with the ending.

Monopsony means there’s a dominant buyer, not just a single buyer.

Fortune was talking about it almost 10 years ago.

https://macdailynews.com/2011/07/05/how-apple-became-a-monop...

Of course they’ve been accused in the Supreme Court of being a monopsonist with regard to the App Store, but that’s a separate discussion.

(Update: regrettably my economic theory is weak, so while I think it makes sense to apply the term, after more reading I can't argue the case with a reasonable level of conviction.

Certainly there should be some way to describe a buyer who locks up a supply of components to the exclusion of competitors, as Apple has done on multiple occasions dating at least to the original iPod hard drives.)
> I think X86 is the only modern ISA family that still have a separate address space for I/O. It is not used today anymore, but it exists somewhere deep in the chip, and its legacy kind of messed up how the entire wider memory, and cache systems on X86 were designed.

Internally it's just a bank of memory these days. You can publicly see how HyperTransport has treated it as a weird MMIO range for decades (just like Message Signaled Interrupts), and QPI takes the same approach.

Some states are what is known as "all party consent" states, while others are "one party consent" states.

In all party consent states, it is illegal to record a private conversation unless everyone who is being recorded is aware and has consented to being recorded. In one party consent states (which are the majority of states), only one person (presumably the person doing the recording) needs to be aware of and consent to the recording.

That difference can obviously make a huge impact on the legal ramifications of recording. For example, during the Monica Lewinsky/Bill Clinton affair, the only person actually indicted for a crime (later dropped) was Linda Tripp, who was brought up on wiretapping charges for surreptitiously recording Lewinsky. This only happened because Maryland is an all party consent state.

This is also why customer service calls start with "This call may be recorded for quality purposes..." - it's to inform you that the call is being recorded if you happen to live in an all party consent state.

> Because the fervor doesn't match what I see in real life, I really do wonder how much of what's happening reflects actual public sentiment, and how much of it is the result of more subtle, nefarious things at play.

Even though it's one of the biggest online platforms, it's still a niche demographic. It's pockmarked by enough differing opinions that you can feel like it's a good representation, but the US has 320 million people in it, and it's hard to find concrete stats but it seems there are around 30-45 million US reddit users. Only some of them would comment on any particular topic, so what you're reading is a curated voice of a particular demographic self selecting their participation in various topics.

As a microcosm of this, checkout the Motorcycle subreddit. You'd be fooled into thinking everyone rides with full leathers and helmets on, and that the entire motorcycle community feels really strongly about it, and that it's a rare sight to see someone without gear on. But it's extremely common to see people riding without full gear in the real world.

That's why all these big political shakeups take that bubble by surprise. Reddit didn't think Brexit could happen, they didn't think Trump 2016 would happen, and it doesn't matter what your political flavours are, my conclusion is that Reddit as a hive mind doesn't really have that good of a grasp of reality.

Getting rid of accommodations in general is not the right thing to do, and I am very glad that you were able to get the sorts of support you actually needed, as opposed to just the cookie-cutter extra time on exams.

That said, giving time and a half or double time on exams to anyone who takes the time and money to track down a compliant enough medical professional to diagnose them with ADHD is not the right thing either. And yes, some people really do have ADHD and need various support, not limited to extra time on exams, to succeed in the school environments we have created. But _so_ many people are diagnosed with ADHD who have nothing of the sort...

Anecdotally, my acquaintances who teach at elite liberal arts colleges say that 25-40% of their students nowadays are receiving extra-time accommodations, a sharp rise over just 10 years ago. It's possible that the prevalence of ADHD and various mental health issues really is that high amongst high-performing teenagers nowadays; the college admissions crapshoot and lead-up to it surely is not helping with mental health. But I find it much more likely that there's a significant amount of gaming the system going on, unfortunately.

Little by little. It’s okay to get it working without understanding all the parts, and revisit or rewrite sections later. It’s also okay (not just okay but recommended) to let this take longer than a weekend, and dive into any rabbit holes that interest you as you go. It will take longer than a weekend to fully understand all the parts, much longer if you want to do it well enough to be able to write all the parts on your own.

Personally I absolutely love learning math and using it to code up programs that make pictures, learning and applying the trig and linear algebra is pure fun for me, so if it interests you go for it, I say. :)

Exactly. The author misunderstood Dijkstra's essay entirely, or perhaps just wanted to stir up controversy.

Sorry, but this, by itself, is a totally meaningless article. There might be an actual scientific advance here, but if so, I have absolutely no idea what it is. "100 million degrees" may sound impressive, but it's completely trivial to create a plasma at that temperature; plasma temperatures are typically quoted in electron-volts (eV) or kilo-electron-volts (keV), and a temperature like this probably corresponds to somewhere in the tens of keV. You can make a plasma like this in your garage, and run it as long as you like (there are guides on YouTube). But it won't produce net energy, ie., you won't get more energy out than you put in. To know how impressive this is, we need to know:

- Was net energy produced during this time?

- How much plasma was there, ie, how large of a scale was the experiment at?

- How dense was the plasma?

- How repeatable is the experiment? Could it be run again sustainably, or did it fry all the equipment with fast neutron radiation?

The article doesn't seem to mention any of these, and without them, "100 million degrees" is meaningless.

Your viewpoint leaves out a larger number of people who want security (as recommended by experts) and convenience without having to understand all the nuances or complexities involved in a solution. Such a description also makes it very hard to recommend Signal to lay people because they don’t know or care much about security but do want convenience. If Signal is meant to be for a small echo chamber group to use, this is fine. If not, the convenience aspect cannot, and should not, be ignored to increase adoption.
