I tried the HP35s of a friend for a few days. It is globally a nice RPN calculator and not too expensive for starting. But I don't want to get one because this calculator have a quite long list of known bugs [1] that have been sitting there for more than 10 years now, and HP hasn't fixed anything yet!

If you are a grown-up children like me and just want a pretty expensive toy, I can recommend the SwissMicros DM42 [2] (I'm not related to them in any way, just a happy customer). The made an adaptation of the HP42s for the modern world: «34 decimal digits of precision, with exponents ranging from -6143 to +6144», based on the excellent Thomas Okken's Free42 [3], big and nice screen, USB connection for loading/saving programs, save and restore of the calculator state, and so on!

And being based on Free42 you can get the emulator on your phone and share the programs with the calculator. You then have the same "calculator" everytime with you, no need to get used to another program/interface on your phone.

But the facts are less fun than my indignation!
this is exactly what I wanted to criticise by my comment. I don't think these rankings are that important because they don't capture what the (original) article wanted to measure. There's only one stanford, which might be better than every other university out there. But there are a lot, often way smaller, universities out there that produce fantastic research. You have to add them together.
Yes, an environment where prisoners fight other prisoners sounds much preferable to learning a trade.

Anyway, the mods have deemed "thou shalt only post five comments every three hours," so... See you tomorrow.

Also the right teacher can make all the difference. Telling victims "Shut up and deal with it" isn't too productive, though it's the usual advice.

EDIT: Since I can't reply, I'll just post it here.

You'd be surprised. Economic activity is the only reason we don't resort to violence on a daily basis. Giving kids something to do other than posture might go a long way.

Woo, replying via edit is fun. I wonder how long I can troll the HN mods before all my comments drop to the bottom automatically again. After all, when no justification is given and your emails are ignored, why obey arbitrary rules or put in effort toward being a good community member?

EDIT2: Hmm, if I implied manual labor, I didn't mean to. A programming apprenticeship would have been amazing, and most trades are becoming knowledge-based anyway. Even a mechanic is less manual labor and more creative diagnostic.
I am sorry, but probably the doctors you were seeing were simply incompetent. Auras in migraine can be almost anything, even intestinal pain (or diarrhea in some cases).

Also, the paper simply describes a new observation in a very well-known fact. Nonetheless, that the vagus nerve IS connected with the gut is known probably known since Vesalius' time. The paper does not describe or explain your intestinal pain, neither gives you any kind of "I told you so" right against your physicians.

Arrogant physicians is one thing, incompetent is another.

Tax in Denmark is also very high (I keep ~50% of my salary) but there are a huge influx of graduates from around Europe because there are plenty of jobs, it's a very fair society, it's so comfortable to live here, English is widely spoken, and if you stick it out long enough to have kids you'll reap some of your taxed kroner back!

Salary is important, but there are many other factors (at least, among my non-Danish friends).
No RPN, no deal, sadly.

Have a look at the Swiss Micros DM-42L, it's a thing of beauty.
"You seem to be confusing /opt and /usr."

It is very unfortunate for me that it seems this way to you, but as someone doing precisely this kind of engineering for almost three decades, I can assure you that this is not the case.

"native package managers should install binaries in /usr/[s]bin and libraries under /usr"

Unless one is an operating system vendor (like Joyent, redhat, SuSE, Debian, Canonical, CentOS, ...) third party and unbundled applications must never be installed into /usr: by doing so, one risks destroying or damaging systems in production in the case where the vendor decides to deliver their own version of the same software, and the vendor's upgrade overwrites one's own software and configuration. Long story short: don't deliver your unbundled software into someone else's space. /usr belongs to an OS vendor and to that vendor alone (vendor in this context also includes volunteer operating system projects one is not a part of).

/opt, /etc/opt and /var/opt exist for a reason. Refer to the filesystem(5) manual page on illumos and the LSB FHS specification, sections 3.13., 3.7.4. and 5.12.:

http://illumos.org/man/5/filesystem

http://refspecs.linuxfoundation.org/FHS_3.0/fhs-3.0.html#opt...

http://refspecs.linuxfoundation.org/FHS_3.0/fhs-3.0.html#etc...

http://refspecs.linuxfoundation.org/FHS_3.0/fhs-3.0.html#var...

section 3.13.2., Requirements, explicitly states:

No other package files may exist outside the /opt, /var/opt, and /etc/opt hierarchies except for those package files that must reside in specific locations within the filesystem tree in order to function properly. For example, device lock files must be placed in /var/lock and devices must be located in /dev.

I've literally seen more than 50 doctors for this over the years. I would estimate about 4 or 5 were great people who actually made a real effort to help me.

The rest were both arrogant and incompetent, and some have even caused me severe iatrogenic harm.
Coming from the perspective in security, the one that says biometrics are identity tokens or user names, but not authentication tokens or passwords, the concept you present is reasonable.

However, let’s not simply dispose of the conversation, and leave it at that. There are quite a few more twists and turns right around the next bend...

Which takes a cue from the idea of using tracking pixels, browser fingerprinting and cookies at all. If I visited your website three days ago, and explored a few link paths, would you be so kind as to show me the same website you show to everyone, instead of modifying your website in confusing ways, so as to either extract value from my actions or reduce them to limited options that act against my normal inclinations?

So, with that, a deeper realization starts to develop, that simply “asking people to be nice” within the context of rational facts isn’t good enough. Yes, faces aren’t secret. But the unflinching long term memories of biometric recognition systems, operating with direct connection to systematic business rules as brutal as any cold-blooded algorithmic stock trader, looking at user names like ticker symbols, cannot simply be trusted to be nice.
I wonder if it'd just be easier for high schools to convert over to a college model: students are free to pick courses corresponding to their preferred times, and to leave and enter campus on will. Of course, there will be incentives to consider -- why would a high schooler attend their classes if they're not paying directly out of pocket? In contrast, a school district would try to maximize the attendance rate as that's how funding works (at least in California).

In hindsight, there's always a tension between high schoolers and those who administrate them; it's never a partnership since teenagers are quick to abuse / misuse a privilege.
The HP-28C and HP-28S were clamshells, along with their business counterparts. Great calculators, although the 28C was a bit tight on RAM.

I had a 28C, 95LX and 200LX. The modern equivalent of the latter would be the Planet Gemini.
I joined a company which had already IPO'd, 1 year before I joined. And had had 14 years of its runway. They gave me some options, which would mature in 5 years. During that period, the stock exploded. Which the company founders, themselves never expected, else they would have given off much less to employees. Some other employees who had the stock matured, sold it.

They gave me stock options worth 300 $ but it increased 2000 times, in a span of 10 years. It increased so much, that I sold it eventually(to avoid all eggs in one basket). Got myself a house. Loan free. And started my own startup. Which I run till date.
I really don't think sending kids off to learn a trade is going to change America's problem of violence. That's a deep-rooted American cultural problem and a big reason why I left (having been a victim of crime several times).

Interesting idea :)
> upset that they didn't jump up and down in amazement

There's that aggression again.

No, I'm upset about paying someone who mocked me and decided not to do any work because I was too pathetic for someone of his/her status.

I am an expert in my field. Many people I work with suggest things that I know to be wrong. I have NEVER mocked or acted vengeful. If they choose to continue with their ideas that I disagree with, that's their right. Is it really that hard to be respectful?

In every event that I've related in my posts, it was the doctor who was unwilling to give the most basic level of respect.
The hole needed for inspection (if any; inspection need not be visual) can be a lot smaller than what’s needed for adding a weld.
I remember having TRIZ lessons at school, in fifth grade. It was the nineties and schools were trying out new approaches. The most valuable thing I remember was the idea that a problem should solve itself, within its system, without introducing new elements.

Searching for Visually Similar Artworks
I'm guessing it's less just the high taxes, and more that people feel like they're not getting much for their high taxes. A common theme in any American article talking about the Nordic model, for example, is quotes from people saying, "yeah taxes are high, but at least the government provides a lot of useful stuff from that."
That’s probably a good reason to stick to wintertime in winter and not summertime (the EU decided to drop time ch ages 2x a year)
What is your estimate on how many of the Danish own land? Do people anticipate price of it growing faster than salaries in the near future?
Not the parent, but I grew up in the North of Scotland where it gets dark between 4-5pm for several months of each year, and as a teenager I could never sleep before 1-2am.

I was always forced to get up early, which of course resulted in me being extremely tired during the day, which negatively impacted upon my life (academically, relationships etc).

Seems like there has to be a better way.
Agreed, but not everyone will take time to learn things later on.

IMO, general level of education is important to fostering future curiosities.
Doctors in Germany are heavily encouraged to produce a phd thesis during their education. The way that usually plays out: they struggle to do good science while laboring to complete a degree that essentially has them memorize an encyclopedia, and they're used by PIs and postdocs as lab monkeys or scientific errand-boys, helping to chase down someone else's obscure 2nd tier side-theory, all while earning the scorn of their academic colleagues for being pale imitations of actual scientists.
Yet plenty of people have relocated to Denmark, Sweden etc because the extra quality of life is worth paying for.

I know two who did, neither now intend to ever come back to the UK with its austerity and constant wish to move in the US direction. One later got relocated by his firm from Denmark to Sweden.
I meant that in the past tense (which rereading my comment was not how I wrote it!), I'm super excited for F9 to start taking people to ISS!
I do use Safari on the Mac (and Firefox for some things). Safari uses resources far more efficiently, it has a reader view, and its layouting doesn't make the page jump around quite as much as other browsers do.

Many websites are barely usuable in Chrome but acceptable in Safari.
According to studies made in UK that I'm too lazy to find; yes.

It's dark in the morning too, maybe going to school before dawn is the major problem, given that the schools are closed in the summer.

I've heard of doctors prescribing melatonine, which is absurd when the problem basically is cultural.
Ask HN: What programming languages a CS undergrad should know?
I am a faculty member of a CS department currently designing a new "Advanced Programming" course for undergraduate students in their 2nd year. What programming languages are an absolute must to know when they graduate? Currently they learn Python, Matlab, Go in various courses. The dilemma we are facing is to choose between old languages like C/C++, Java, C# or move on to modern languages like Rust or functional languages like Scala, F#. Is it bad if a fresh undergraduate doesn't know C/C++ or Java? Are they here to stay for decades to come?
Efficient supply chain saved Apple when Steve Jobs was still around.

Now it's their vertical integration and just how good they are up and down the stack compared to the competition.
I think a lot of mistrust comes down to an "us" vs. "them" mentality that forms in societies which are segmented or where resources are scarce. The most straightforward ways to remedy those situations are the redistribution of wealth or an increase in total wealth, respectively. But how do either of those happen in the country the size of Italy? Maybe you need a shock to the system to kick a sick society out of it's negative spiral, as you put it. The world wars acted as one for much of Europe. Maybe climate change can be the next one.
Insider here: The sort of shit which happened here -- with "confidential" student data misused -- is rampant at MIT. Survey map to dorms isn't even the tip of the iceberg. My guess is that at some point, we'll have a Watergate-grade scandal, but I've been wrong about these things before (Equifax is trading above where it was January 2017).
Pretty cool potato cannon they built though.
I see your point, but also you do not give health advice to other people as a profession. It's more akin to the mechanic dealing with people coming in with cars that almost all have the same issues, but then every now and then somebody reads something online about some extravagant maybe-it's-lupus kind of diagnosis, and they just roll their eyes.
It is the case further north too, where winter daylight is 0-3 hours.
Ok, but the new iPhone has a huge screen, great browser, email, 64gb ram, > a million apps, 40x the radio bands, 30x the resolution, 3x the battery, 100x the speed, video, and more.
Businesses can also fail at implementing existing solutions and burn huge amounts of mones trying to do so.

And yes, Musk is relevant in a discussion about SpaceX and to degree Tesla. Have both endevours been "visionary" to a certain degree? Sure. At SpaceX I'd agrue that it was not Musk himself who designed, say, the Falcon 9 all by himself. Sure his education and background helped a lot.

At Tesla, the approach was disruptive as well. Especially tackling the lacking charging infrastructure as well. That gave him a huge head start, mass-production cost a lot of that head start already. SpaceX profited a lot from vertical integration, Tesla did not. Seeing Musk as some kind of genius in everything he does is doing two things, none of them good: 1) Reinforcing Musks pre-existing sense of superiority (again, based to a not inconsiderable amount in truth) to levels that are hurting and 2) making people an approach that worked once (vertical integration at SpaceX for example) will work elsewhere as well.

This is in effect suppressing diferent opinion and the free exchange of ideas. Reality usually punishes you for that at one point or another. And it would really be a pitty if either one, Musk, Tesla or SpaceX would be in the future.
I think this really depends on where you are. When I first developed post-infectious IBS 15 years ago, I went to quite a few Gastros who knew nothing but: scopes, check for ulcers, tumors, diverticula, etc. - and when it all came back negative they happily declare IBS, pat themselves on the back, and tell me to destress, see a shrink, and not come back. Diet, gut flora, intermittent fasting, FODMAPs, none of those things were mentioned once.
Really nice concept!

I like systems that keep your work focused & simple.

You'd probably do yourself a favour by avoiding "good guy, bad guy" thinking. In their position, wouldn't you act the same way? Doctors have a finite amount of energy and time to spend on their job. What is a resource efficient way to maximize the utility of the sum of all patients? Is it, (a) invest an exorbitant amount of time on one patient whose symptoms isn't supported by very well funded (much more highly funded and rigorous than what you, the doctor, could ever invest on your own) research (which is probably a true positive only a small percentage of the time), at the expense of other patients, or (b) trust the current scientific consensus (at the small but occasional risk of being wrong)?

It's not "arrogance", and you shouldn't think of what's happening now as "vindication". It's just cost efficiency at the (unavoidable) risk of occasionally being wrong.
The business of voluntourism: do western do-gooders actually do harm?
In 2003, for most people, the flagship Razr cost £99, or nothing. You were paying £20 or £30 a month for mobile service in a contract that gave you a new phone every 12 months. No benefit or discount for not taking an upgrade when it was available.

> Changing the operating hours of an institution so central to the community is far from easy. It requires strong leadership and adjustments by school bus companies and businesses offering services like child care and extracurricular clubs.

Here's the elephant in the room. High schools start and end earlier with the idea that older kids can watch their siblings.

I'd say a lack of public commitment to child care is also a big reason for the low rate of young people having children commentators like to wring their hands about.
There is not a lot of vertical integration in Apple's physical supply chain. Screens are sourced from Samsung (or have been last time I checked), phones are assbled by Foxxcon (same as above, might have changed).

Managing all that is what set's Apple appart from others. Besides brand, design and such. I'm in no position to judge the software part.
Drastically reduce administrators. Give the kids something like 25 to 50 cents per class attended.
That they are "hardcoded" in this way is one of the major points of this piece. Changing the curriculum, whatever its merits or demerits, is not going to result in fewer teens dying in car crashes.
That's how it works in Finland in lukio (upper secondary school between 9th grade and university), we picked the courses ourselves and left/entered campus on will. Looks like the course-based system was introduced in 1982.

And personally I did prefer course instances that were later on the day over those that were earlier.

We still had mandatory lesson attendance, though, unlike most university courses.
Hey! Yeah there are bugs in the emulator so it's not time perfect, I've not really touched the emulator code in about 5 years so will take me some time to get back into it.

Thanks for the tip about requestAnimationFrame (/u/knackers mentioned as well) I'll look into it! That's what's good about sharing this stuff - you learn something new!

I'll probably tinker with the project here and there, I want to implement another cartridge type that for some reason I left out, I found a ROM last night that wasn't supported and I think it's MBC2. But I don't intend for it to be a perfect emulator or anything, more just a sandbox to play around with. There are definitely better emulators out there that strive for accuracy.
At any given moment there usually seem to be one or two New York Times articles on the HN front page, which I assume means a reasonable proportion of us are subscribers.

I don't really see what's wrong with the subscription / paywall model, other than it means letting go of "information wants to be free" dogma and admitting Rupert Murdoch was right about something. At this point it seems preferable to the ad-driven business model.
It's inevitable because of the evil people who promote it. A little more cynicism and skepticism about politicians' motives is in order, I think.

> That statement sounds too simplified.

Having worked with DRM for 10 years, I can confirm that while very simple, that statement is entirely correct. He says this is the reason the secure boot process exists, not that this is the only benefit.

> How about X, Y, Z

Those scenarios certainly benefit from a secure chain of trust but they are not what brought it about. The whole secure boot chain exists because of companies that require DRM to access their content.

Samsung wants Netflix to play the best content on their devices. That's the only motivation that has ever mattered to device manufacturers.
To link the two approaches, it can be useful to understand the wave function as an object that takes values in a tensor space of C^n. In particular, if we had two particles, both spin-1/2 (C^2), then at the position configuration point {x,y}, the wave function takes a value in C^2 tensor C^2 where the tensoring is not done over the particle numbering 1 and 2 (which does not exist), but done over the set {x,y}. This is how one naturally leads into the choices of bosons vs. fermions.

To say it another way, the configuration of the system remains rooted in position in physical space and it is the value space of the wave function where spin resides. This is made most clear in Bohmian mechanics, where the position of the particle is always defined in the theory, but whether a particle will end up in the spin-z up or down regions does depend on the experimental setup. One can arrange experiments where the particle, due to symmetry for example, will always go up given the same starting point even if one flips the magnetic field in the Stern-Gerlach device so that the experimental conclusion would be spin up in one scenario and spin down in the other. Same exact path happens in both cases, but the spin value conclusion is the opposite. That is to say, while position is determined ahead of time, spin is not. Spin is not a real property of the particle; it is a property of the wave function.
