The Mac mini in no way can be considered "aggressive pricing". It is well over the price of anything in its range. I wouldn't doubt that Apple's margins on the Mac mini are higher than on some of the portables.
Programming languages are more general than the problems they solve. (= feature, not bug)

> they also are a profitable business that sells stuff that people want to buy

[citation needed]

Just like the other MLMs (or rather pyramid schemes, because that's what they really are), they sell a (unprofitable) lifestyle using deceptive marketing. The products are secondary (they're just there to keep regulators at bay) and are always sub-par and inferior to what can be found off-the-shelf.

I think vocational education could have been better conveyed online, but with perfect pre-recording and editing. Coursera and Edx are a good example for a forerunner though.

As a college student myself, this year, this semester is the worst for me -- I felt really lazy without any faith to keep me going, that with face-to-face activity I feel like I'm motivated to engage. But I hope this semester really is the exception.
Why was the Itanium processor difficult to write a compiler for? (2015)
If it's an fda approved drug, I'd be shocked. You see how strictly they're coming down on contamination in the antacid space. If it was a supplement calling itself a medicine with a "these statements have not been evaluated by the FDA" label, then I'd be surprised if it actually did contain what it says it does, and do what it promises to do
What about the language? I've heard that the best way to learn Danish is to be born to Danish parents.
I got my son at 30. I'd say noone is ever ready and you just gotta learn parenting as it happens. On the other hand I fault noone to wait or even forego parenting as you can really kiss your freedoms goodbye.
Not all people are fully aware of the causes and results of their sins and are taking that all into account. There's so many people that smoke and wish they never started. Why did they start in the first place? Even my generation (I am in my 20s) is affected by it, although we grew up with our parents addicted to the stuff.

A lot of these issues are offloaded to healthcare. It is the government's job to figure out strategies to reduce the load on healthcare systems. It's definitely a hard problem to solve, it could all end up in a failure, but it's important to discuss it before stamping "FAILURE" on it. Maybe there are good strategies that do work?

To give an example of what works: when I was young we had many lessons about what smoking does to you. We discussed the effects of it and were shown pictures of gnarly lungs. That, plus how my parents smelled after smoking, definitely helped me make up my mind about smoking. Sugar is way more difficult than that, as you get addicted to it before you ever realize the effects of it. After years of just eating sugary foods and drinks, regular food starts to taste bland. I remember as a kid I hated the taste of water - how insane is that?!

A tax is a worthwhile strategy to explore in my opinion.

> but that is something that many miss a lot when discussing Rust virtues.

When someone says “Rust is thread-safe”, Rustaceans in one common voice reply, “Rust is data-race-safe”. After that, folks get into a good conversation about what the difference is, and learn about deadlocks and other issue in threads.

Generally speaking though, it does mean that multi-threaded programming in Rust is memory-safe, and won’t introduce a significant class of bugs that you see in C and C++, where so many exploits come from.
If you can get 1g of acceleration, the trip to mars is a couple of days, I don't think you could ever get that with solar.

Edit: reaction mass becomes the problem, say to move a ship 10^4kg, 2x10^9 m (the distance to mars) at 1g, I adapted an answer from [1]

So say the craft has a mass of 10^4 kg. To accelerate at 1 G you need F = ma = (10^4 kg)(10 m/s^2) = 10^5 N. To get a force of 10^5 N over 2x10^9 m (distance to mars), you would need (10^5 N)(2x10^9 m) = 2x10^14 J, lets say 10^14J. Antimatter is the most energy dense material we know. To get that from antimatter you would need m = E/c^2 = 10^14 J/10^17 m^2/s^2 = 1gram. So you'd only need 1gram of antimatter - is that right?

CERN has made around 1 nanogram so far, 1gram would cost around $25 billion in a 2006 estimate, its down from $62 trillion in a 1999 estimate [2], so it may be feasible one day...

Edit2: The moon is 4x10^8m, so you'd need 0.1gram of antimatter, you'd be there in an hour or so.

You are exactly right. It is a travesty that the food pyramid is provided by the Department of Agriculture and not the Department of Health and Human Services. USDA whole job is to make and sell food at scale to make sure the country can always be fed. They have an insane conflict of interest. We need to stop propping up corn and soybeans.
There are 'heroin alternatives' that people switch to in order to treat their addiction - mostly substances that act on the same receptors but aren't as addictive. Whether they are all cheap, legal, well-known and/or easily accessible is an entire story altogether.

Because they've studied this and "sugary drinks remain the largest source of added sugars intake in the U.S." (quote from the article). If sugary pastries and candy bars were the largest source, they would be targeting those, but they aren't, so they don't.

At least in Chicago, they included diet drinks in their tax.
Just to be clear, uranium is not literally burned in a nuclear thermal rocket. Unless things are very very wrong and you’re not going to space today. Nuclear thermal propulsion is simply using a fission (or more speculatively fusion) reactor to heat hydrogen gas which is then allowed to escape at high velocities from the business end of the rocket. In theory the heat source could be anything, but very few things offer remotely as much W/kg as nuclear.
I came across Arybo while working on the binary but I can't remember why I didn't use it, this is vague memory now. Anyway it does the job in one go, I added an edit.

Expect it is not just configuration. It is hardware too.
I am member in a internet provider by students. We couldn't allow an UDP since we have an agreement with our uplink that we will make it impossible to host outwards facing services. To guarantee that for UDP we would need a stateful firewall, which we didn't have.
Due to agreements without uplink they want to have full access to our firewall and since they only use Cisco, we are required to do so too.
This means we had to shell out €€€€€ to get a firewall from Cisco and we had to put aside money to do that for years. Then our (old) core router had 90%+ load during testing of the firewall since the hardware UDP support it supposedly had was not up for the task. So we had to buy a second core router where we lucky weren't bound to Cisco due to outside obligations another €€€€ investment.
It's not just stupid configuration, sometimes it is just means and it takes long strategic planning we can do as a non-profit to afford such things.
I don't think there can be a universally accepted answer to this, as there are so many different user priorities for laptops.

Having said that, I think the top requirement for most laptops is that "it's gotta run what I need it to run on day one".

For a huge amount of light users, ARM Macs are going to satisfy that requirement easily.

Once you move up the food chain to users with more complicated requirements, however, it's less of a slam dunk... for the moment.
The point was about agressive pricing and you keep referring to high margins. You can still be agressive on price (based on what the market commends) and have high margin. You're making a separate point and you fail to notice it.

"This had the side effect of sugar being a cheaper food ingredient than most of the alternatives"

What are these alternatives?
I was having another one of those moments yesterday where I was questioning the value of higher education while reading a HN thread about teaching yourself CS. There was a healthy debate about whether the typical CS curriculum helps a modern software engineer at all. Some thought the degree was stuck back in the 70's. Others thought there was value, but had trouble articulating it. It seems that when the information received was divorced from the credential, the value dropped precipitously. And this is a hard sciences degree with many "universal truths" to teach. Things get even more squishy when you get into the humanities which are much more idea, opinion and discussion based.

As the linked article points out, employers often look for the degree, but do not believe it is much of an indicator of quality and don't expect new grads to walk in the door with the needed skills. As a former recruiter I think that sentiment is pretty spot on. I don't think I ever asked a candidate about the details of their education. It was just never relevant in comparison to their experience.

So that leaves the on campus experience, which I personally think is amazing. It's like living at a country club for 4 years, crossed with a huge expansion in your world from living at home and going to high school. The new ideas from the classes are just a small part of the new ideas you get exposed to from other students and campus events. Plus with the increasing independence, it's a great gentle introduction to adulthood. Unfortunately all that is not available during the pandemic.

So the content of the classes is in question, the value of the credential is in question, the cost is ballooning and the on campus experience is on an uncertain hiatus. If ever there was a time to disrupt higher ed, that time is now.
Earth is really big.
I was just thinking the other day how refreshing it was that HN had not had many diet and nutrition links on the front page recently.

Like this one, they tend to be filled with highly polarized and extremists views and conspiracy theories with very little hard science or data to back things up.

I thought it had already happened, but I hope someday these topics can be penalized from ranking highly like other issues that tend to have very low quality discussion.

Edit: To clarify, I’m referring to the discussion here on HN as opposed to the article.
I've personally found that sometimes using a tool like PlantUML[1] or others (lot DOT graphs) to sometimes be easier to create visualizations with. It seems to allow me to focus more on various pieces as the big picture is built. It also seems to provide a great way of ensuring various parties thinking is similar. There are many more diagram types than many realize.

We need, in fact the industry simply REQUIRES, in-depth oral history journalism and retrospectives like this. The "gaming industry" is 40+ years old now, and there have been absolutely pivotal works in that time. They deserve to be interrogated and documented dispassionately and with rigor.
This seems like a bow out and still I have no answer, just an assumption. So once again, what benefit does humanity have for decreasing poverty instead of the country decreasing it themselves?

I still remember a chat I had with a guy around 2012 or so. His idea was basically about.me, but only for realtors, and worse. Even as "I have a million dollar app idea!!1" ideas go, it was pretty terrible. He wanted me to write the entire thing "in a week or two, right?" and got pretty offended when I laughed at his proposed 80/20 split. He also stormed out of the coffee shop we were in when I laughed again when I refused to sign the ex post facto NDA he pulled out.

I still think about him sometimes and wonder who he's bothering now.

The way a pilot's rating works is you get your private pilot license which is the same as a driver's license for most 'general aviation' planes. In those, you are required to demonstrate stall and engine out recovery as part of the test. Theoretically, you can get your PPL with around 20 dual instruction, 20 solo. I solo'ed around 8 hours, and spent another 30'ish learning how to navigate and fly when things went sideways. For me, hour 7 was stalls and spin recovery. (fun, but glad I skipped lunch)

The Instrument rating allows you to fly IFR (in clouds and higher controlled altitudes. One of the tougher ratings of the series.

Commercial allows you to start flying stuff for hire. This usually starts with dropping parachutes or pulling banners. Theoretically flying someone from A to B and getting paid for it. Ironically, some gigs don't need Instrument to fly commercial. Brother-in-law does helicopter crop dusting and fire fighting on just a commercial ticket. You need 250 hours to qualify to take the test.

ATP is where you fly the big stuff. I forget the passenger/size limits - want to say it is near 20 seats. This is the rating where they ask for 1500 hours minimum before they allow you to take the test. For most pilots, this is where you start in the regional airlines and start working your way up to the majors (like Delta).

Unless you add a rating, every couple years you are required to demonstrate you still know what you are doing. Every time I've worked with an unknown instructor they make you go through the same stall/failure drills.
It's more of a trial and error kind of play. It really helps to quick save/quick load a lot to figure out what you can get away with.

Sugar is not made artificially cheap. It's actually more expensive in the U.S. due to government control over the market (production, imports, and exports). If the government subsidies/control was not there, the U.S. sugar market would disappear as it cannot compete with the global market. You'd see a massive reduction in sugar prices and a lot of U.S. farms go under.

In fact, big customers of the sugar companies lobby for this to happen all the time (think Hershey). They'd love the U.S. sugar industry to collapse. It's a constant battle.
WordPerfect through 5.1 used XOR encryption. With 5.1, as I recall, you had a dozen or so known bytes early on--nulls or spaces, I forget--so it was trivial to get any password of a dozen or fewer characters. With 4.2 it was simpler to build a lookup table of the keys--the key was formed by XORing the characters of the password with a logical shift after each character.

I believe that Sendero Luminoso made the mistake of trusting to WordPerfect's encryption, and suffered for that after one or more of its computers were seized in a raid.
At minimum every sin should be taxed because you’re sinning doesn’t exist in a vacuum. Your poor eating habits affects everyone around you to an extent. It does need to be done in conjunction with education though. That’s why I think smoking tax has helped reduce smoking. A lot of education around the negative side effects. I guess taxes can fuel that no?
> In the end, the problem is not the value of the four-year university degree.

It's not worth it IMO, even if education is virtually free here on the better side of the big pond.

Even at 0 EUR, it's still a lot of time and effort that could be focused much more effectively.
Yeah, I was kinda disappointed by the end. They really didn't gain that much performance.
12% is a pretty decent improvement.
How much of a role do the certification bodies (the groups who decide who can grant a bachelor's degree) play the cost of college tuition? I'm a big fan of the classical quadrivium, trivium, and Great Books model of education; why couldn't one complete all of the studies at home, spend six to twelve months in an intensive course of examination and debate to validate the level of education (which could be done online) and receive a bachelor of arts in "the humanities" (or bachelor of letters or whatever one wants to call it)? I think we would have a much more powerful crop of critical and logical thinkers if education were handled thus.
> True, but that is something that many miss a lot when discussing Rust virtues.

The large majority of comments I read about Rust safety claims are very explicit that Rust provides memory safety and data-race freedom.

You seem to be arguing that these comments are leaving out important information by not clarifying that "This does not mean that Rust prevents all bugs, e.g., you can still write programs with logic bugs, race conditions, dead locks, DDoS, ... and the list goes on and on... in Rust".

If somebody does not know what that "memory safety" and "data-race freedom" is, they should just ask, but if they don't, and they make an incorrect assumption, then its kind of their fault, not the fault of whoever wrote such a comment for not mentioning all the things that these two properties do not guarantee.

Also, it is actually trivial to build Rust programs that prevent some race-conditions, like deadlocks (just a cargo flag away), so if anything, I'd complain that people being "too correct" by restricting themselves to "data-race freedom" are leaving out some important advantages of Rust.
Face it, software is judged by amount of recent commits.
You can't have lots of commits if you build right from the getgo.
Therefore "software built to last" is doomed for obscurity.
And your pseudo 60 second detective work is an example of another problem: you speak authoritatively on a topic you just learned about.

The Missouri Highway Patrol retracted the report from the Missouri Information Analysis Center (MIAC) in 2009. They removed the mentions for Ron Paul and Campaign for Liberty.

The Highway Patrol launched an investigation into the origin of the report. The Lieutenant Governor Peter Kinder called for the suspension of the Director of Public Safety “until those responsible have been identified”.

We personally investigated the story in 2009. I have seen the report. I served as a national Ron Paul campaign person and currently work within the IC and international law enforcement.

Please no. I have had many project managers and the worst have always been new grads. PM is largely political, and they don’t teach that in schools. Instead you have an essentially a child running the show who thinks they will be the next Zuckerberg if they launch their product just right. They are some of the worst offenders when it comes to regurgitating pop psych/business management articles, but lack the context that comes with experience.

I won’t join a team if a PM is a new grad. Maybe there are some great young PMs out there, but I find them to largely be egotistical children.
Scientists provide new explanation for the strange asymmetry of the moon
Your junior colleague is trying to solve a few problems at once. This is overwhelming them, and likely frustrating them. They're trying to simultaneously solve, "Why do I need to represent data visually?", "What data am I trying to present?", "How can I represent this visually?", "How do I map these things in code to this thing on paper?" without understanding any pre-existing solutions to these questions.

In comparison, you have a mapping from "I have a problem" to "this type of diagram will help me solve it."

At my first job out of college, my boss was obsessed with diagrams. He made sure that every person on the project could reproduce the system diagram. This means that I was personally given multiple years of instruction on how to visually represent data by someone who was very patiently correcting me. Are you willing to give someone that type of attention?

If you want them to learn the skill in a useful time horizon, and they're willing to improve, you're going to have to practice with them. Pick a thing they know well. Walk through an explanation of the system with them as you diagram it. Then have them draw the system while explaining it and having access to your diagram. Then have them reproduce the diagram without looking at it. This is the beginning - you'll need to do this a lot before they start to internalize a thing you've practiced for years. Over time, you'll realize that you can leave out some of these steps, and over time, they'll have enough bootstrapping that they can produce novel types of diagrams themselves.
Agree, we need big education campaigns though. So people understand the side effects. Then they can decide to consume sugar at the high price.
Its a real struggle for us. The "doing" part of vocational education doesn't really work for at home because of the equipment needed. Its not like typical lecture classes, since it is damn hard to weld at home for example. Never mind the Commercial Drivers License Training which requires use of the simulator until we are confident you have the skill for the actual big rig.

I would actually say vocational is much harder than traditional classes. Heck, laboratory assignments for the sciences are already computerized and don't lose as much value as vocational.

We have to do hand-on appointments and book work remote.
