Sounds right to me, except maybe #1. I'd add:

9. Keep organized. My experience has been that young people who do well in academia are exceptionally good at keeping on top of things: correspondence, deadlines, juggling different projects, etc. This is especially true the less you work collaboratively. If you're on your own, it's very easy to become a chaos.
what you get out of it depends on what you put into it

If the average quality varies that much, we should be paying a lot less for it.

High prices (in general) imply a level of quality. They don't necessarily indicate quality, but you're not paying a lot for no reason. If the quality from a BMW was highly variable the price would need to decrease to account for that level of risk. In education the student takes all of the risk and pays a high price for it.
Phone vendors customize the default UI pretty heavily sometimes. In this case, it appears they customized it to make it look more like iOS.
Sorry to be so negative on this one but I'm kinda triggered by these "look its that easy" kinda blog posts that fail to adress the common task at hand entirely.

This works for your personal blog with a super minimalistic design. This is completely unfeasible for client projects, or at least it will break your neck in the long run. And chances are your abysmal lighthouse score on WP had more to do with a bloated, mashed together WP setup than with the technology itself.
Seems brilliantly simple yet featured.
But we can compete–and win–on flexibility.

And then the following part describes:

In 2020, Sid left Gumroad to start his own creator economy
company, Circle, together with former Gumroad coworker Rudy
Santino

I fail to see this as any competitive advantage since Gumroad's "employment" approach literally incubated a competitor.
Why does this blog have a loading bar that gets stuck around 99% for me? Every request has loaded and is cached by my browser, yet it hangs at 99% artificially for like 30s.
GPU Programming with PyCUDA:

Amazon is expanding their EC2 feature set so rapidly... The pace is mind blowing to me. Last year, Randy Bias estimated EC2 was pulling $220M revenue/yr:

http://cloudscaling.com/blog/cloud-computing/amazons-ec2-gen...

And he estimated an overly conservative 10-20% annual growth. But given the EC2 buzz this year, and personal anecdotes from my friends and colleagues using it, my gut feeling tells me the 2010 revenues will have increased 50-100% over 2009 revenues.

Is EC2 profitable to Amazon? Likely very profitable if you want my opinion. It is well accepted in the industry that the dominant cost in large scale datacenters is power and cooling --not hardware, not human resources-- and I keep running numbers in my head and the hourly prices of all instance types are well above power & cooling.

Just as an example, we know that this new GPU instance has two 95W Xeon X5570 and two 247W Tesla M2050; assuming (1) a max TDP of 50W for the motherboard and rest of the server, (2) instances are run under full load 100% of the time and always reach these max TDP numbers (unlikely, but follow me for the sake of the argument), (3) Amazon uses servers with 80PLUS power supplies (80% efficient or more), (4) a rather good datacenter with a PUE of 1.3 (power usage effectiveness, which includes overhead from power distribution and cooling; numbers in the range of 1.2-1.4 are often quoted by James Hamilton from the AWS team: http://perspectives.mvdirona.com/), and (5) electricity costs of $0.10/kWh (average in the US, but I know Amazon datacenters are in locations with cheaper electricity), then the hourly power and cooling costs would be:

(95*2 + 50 + 247*2) / 0.8 * 1.3 / 1000 * 0.10 = $0.119/hr

Amazon charges 17x this amount for on-demand instances ($2.10/hr), and 6x this amount for reserved instances ($0.74/hr).

Given these numbers, Amazon must recoup the initial deployment costs very, very quickly... Which is why I also think EC2 must be very profitable.
The article explains that the trees are only glowing because they are being illuminated by ultraviolet light - the energy comes from the UV.

I would imagine that this would be much less efficient than normal lighting and constant exposure to UV probably wouldn't do the trees or people any good at all.
Linux Mint LXDE is very lightweight without sacrificing functionality and looks. I use it on my netbook for several months now, and it works great. Battery life improved 40% since I switched to it, everything works out of the box.

Four failed projects is not something that should discourage you. When you fall off your bicycle and you don't break any legs, you climb right back on it and keep pedaling. You can't really give up technology, you will find it in front of you no matter what you choose to do. You could quit programming however, if you really hate doing it.

If you want to talk about new ideas or even failed ones, you can find contact info in my profile, I am also located in Europe.
They would have to track wear and charge for the depreciation of a local SSD, since every newly started instance is going to want to overwrite much of the contents. It might make more sense to have SSD space available via SAN to any of your instances.
I've made an argument about what wording they use about their discoveries, I haven't claimed that quote to match the currently announced one. It's just their latest news item on the page.
Can you expand on what you mean by "latency" is not a concern? As in, the UI is very laggy?

Alexey Petrov, quoted in the article, subbed in to teach one day in my quantum mechanics class :) It was the first day we were being introduced to the theory of scattering, and I will never forget his intro. He asked the class, “what is scattering?”, waited a moment, and then threw a whiteboard marker against the wall, and answered his own question: “that’s scattering”.
Lots of times, physics classes can be so heavy on math that it’s hard to even remember that you’re trying to describe the real world sometimes, and moments like that were always very memorable to me, because it helped remind me I wasn’t just solving equations for the hell of it :)
Well its probably better than driving out to the store. Since delivery trucks have many packages, the CO2 footprint per package is lower than one person in one car driving.
> I get the nudge I need in the mornings to hit the gym again, I get cheap and healthy food during lunch with no effort on my part.

Let's clarify that this is strictly specific to you.

I and several other colleagues I chat with started doing more exercise due to the pandemic.
While it is sad to see that equipment is becoming a concern in high level running, I found it most disastrous when thinking about the effect of "equipment" in swimming.

Some of the suits that Phelps and folks wore were just so stupidly cutting edge in terms of their effects on stroke efficiency. I think the world swimming organizations have done a better job of regulating here, but again it sounds like ALL sports are required to have their governing bodies playing a bit of cat and mouse to keep the playing field as even as possible.
Are the people in charge of regulating the AI which interprets human emotions better than the AI at the same task? How do we currently regulate humans that interpret other humans emotions? Fairly easy to point a case where AI did poorly. Much harder to compare the current process to the new one. Humans can be assholes too.
> I genuinely don't see the reason why non-cryptographic random number generators exist outside of niche applications.

Because for well over 99.99% of developers, cryptography is a “niche application”.

I’ve never written crypto code I’ve deployed anywhere. If I need crypto, I use the highest level crypto library I can find that people I trust who _do_ know about crypto recommend.

The only time I ever recall non cryptographic random() functions to have surprised or affected me was way back when I discovered if you forgot to seed the random on an AppleII the games I wrote in Basic all started out with the same “random” choices.
There are some limits on characters which can be posted, notably various emoji and some Unicode charactersets.

Though I did find an example of someone achieving bold text on HN (ordinarily only italic is supported via enclosing content in *asterisks*)[1] by way of some Unicode character points.

That's frowned on but not explicitly coded against, mostly because explicitly coding against stuff takes time.

HN uses a lot of soft social pressure for behavioural control. Largely to good effect IMO.

Back in my days, I'd have built websites for friends and some would turn into (badly) paid gigs. If he's got other interests (sports club etc) they could become engagements.

If really he wants to do websites, you'll have to start with JavaScript/jQuery, then graduate to server-side (node, PHP, Python/Django, Ruby/Rails, pick your poison).

Consider that the real dazzle these days is mobile, and it's not that much harder than making websites (or he can make mobile-optimized websites, which can be almost as cool). It might be easier to get engagements on that side at the moment, since most people/clubs/businesses already have a website but they likely don't have an app.
I just read No More Mr Nice Guy[1] and recommend it. I rarely agree 100% with everything in a book, and 90% of this book was spot-on for me. I'll try to summarize some of the advice from the book.

* "Nice Guys" are pushovers because they weigh every action by what would make their lives the most conflict free. Instead, do what you think is best, even if it's scary.

* "Nice Guys" seek the approval of everyone around them, especially women, for every action they take. Instead, do what you think is best, even if it's scary.

* "Nice Guys" often hide the truth (of what they think, feel or have done) in order to avoid conflict. Instead, be honest, even if it's scary.

* You, and nobody else, are responsible for meeting your needs.

* It is healthy and OK to put your own needs first.

* It is OK to ask people for help meeting your needs.

* It is OK to set firm boundaries and tell people "no", and it in fact garners respect, even if people fight it initially.

* We live in a world of abundance, and there is no need to be controlling and manipulative to try to keep what you already have.

I was mostly thinking about the formality of it all. From every court around the world, not specifically american courts.
Example code often skip error handling, because that's not the point.

of course clock_gettime() should have its return value checked, just like you always check the return value of gettimeofday() and time()
No, they don't. They just had Uber Pop.

There is a Spanish Uber competitor called Cabify that does comply with the law. They have professional drivers and cool and clean cars. So yes, Uber could be legal if they want (it implies more effort though as every driver has to have a license)
Thanks for your opinion. I was thinking about giving all modules a priority based on alternative income sources the module could provide(the app for appointments for example) and also considering how relevant is the module in the system.

This way I could change the "refactor this system in 1 year and then we might see the benefits" to "pick several modules, refactor them and add some features/apps taking advantage of it".

"It's not Apple-like."

You emailed the wrong person. It's AT&T, not Apple. They're two very separate companies. To be honest, I've had less trouble with AT&T than any of the other telecoms. This change prompted me to check my data usage for the last six months and I was surprised to find that I actually use less than 200mb a month on my iPhone - these new plans are actually going to save me money.
That's why in every MMORPG I've played, I've ended up with an inventory full of potions I never use. Every time I might want to consume one, I worry that it might not be the best time to use it.

My phone does have limited minutes and that doesn't bother me, but that's because the limit is three orders of magnitude over my average use, and two orders of magnitude over the most I have ever used. I'm only at risk of hitting the limit if I undergo some major life changing event, which I'd probably notice.
Maybe I am alone in this line of thinking, but shouldn't people who are illegally parked get tickets? Ticketing illegal parking is a good thing. It's not in any way liberty-infringing or anything.
I don't have wifi, rarely use it when out. I thought I was a heavy user of the 3g, but rarely go over 150mb a month. I am 3 weeks through this months allotment, and I have only used 50mb so far.

Of course, this does not take away form the fact that they changed the deal 1 month after the iPads release in the US.
yup, if I am on one of these plans, I no longer will try new apps when somebody mentions it, also, i will quickly uninstall /switch off(try to) all apps/settings which sends data to ATT and Apple to make "my" iPhone experience better
Better yet, make automated test cases part of the standard.
It won't matter. For them to have constructed such a biased test shows how much in denial they are. It's pretty depressing actually.
Great find! Not just for the article, but for the idea of 'hacker tourism.' Is that an established thing/industry/practice? [...] A bit of googling turned up this thread, which looks useful for ideas an inspiration:

I'd love to have a version of this I could use to manage my own inventory, and not be linked back to Amazon. Has anyone had experience with a scale like this?

I imagine a simple load sensor hooked up to a microcontroller and a wifi board would be a simple implementation.
Yeah, I feel this way about French.

I want to like the language, but every time I try to read it I can't seem to understand what the words are trying to tell me.
That doesn't matter though; if there is any difference, we can sort out the root cause by inspection.

There are also false negatives: either, or both compilers are wrong, or else the test program is wrong (undefined behavior or non-portable), or some combination of these, yet by fluke the results agree.

That's no big loss; if you're fuzzing, you're generating a lot of this stuff. If this geneated program won't catch a problem, maybe another one will. Individually, the test cases are cheap.
Are there people who have a [strong] sense of identity that's somehow not centred around their ideas? I'm trying to imagine what that looks like?

Maybe "it doesn't matter what I think, I'm $Nationality and that's who I am"? [But does anyone think like that? And isn't that just an idea that informs identity?]
A better idea that a lot of people have is the you should never get married in a month that has a Wednesday in it.

...without taking the price of life into account ?

You are reading it wrong. From the article:

I have adjusted the figures for inflation and PPP based on OECD data.

There are inaccuracies which he points out, but failure to adjust for the price of life is not one of them.

However, if he did make that error, it would only make the results more dramatic. Many EU nations, the Scandinavian ones in particular, are more expensive than the US.
Are you one of the HN mods? I was wondering how to folks know what was published before etc. without a proper search.
Also, "Read Experts" doesn't really make sense. You need another word at the end. Perhaps "Read Expert Predictions" or "Learn from Experts."
Why the following: "the selection pressure at the individual level tends to outweigh the pressure at the group level".

Because "I had 1.8 viable offspring before I died" is more fit than "I had 1.5 viable offspring before I died", no matter how you slice it. Any trait that moves an individual from the former statement to the latter makes that individual less fit, even if it benefits the group, and since the individual is less fit, that trait is less likely to be passed on, resulting (asymptotically) in more fit individuals massively outnumbering less fit ones, irrespective of the impact those individuals have on group fitness.
I remember how slowly high school math moved. How uninspired English class was. The poor curriculum and tools in programming class. imo, there is definitely a primary and secondary education problem vs. the early-life academic environments that helped to produce yesteryear's great thinkers.

Morality usually boils down to shouting matches, so I'll avoid getting into that, sorry. And my job is certainly not high-influence. :)

My tobacco analogy was not trying to say that without tobacco the farmers would starve. Rather, it was about pointing out that quants are merely providing a service that people want. Quants aren't the evil lobbyists, or the ineffective regulators, or the guys peddling to kids. There is nothing illegal about what quants are doing, so anything else is morality, which again I'm not touching.
[CORRECTIONS ABOUND! It isn't as bad as my first napkin suggests.]

Well done scientists[1]! Cue the engineers…

And it must be focused to an intensity of 10 million watts per square centimeter. Sunlight isn't this intense on its own…

Sunlight is about 1000watt/m^2. They are using 100 billion watts/m^2. That is, you would need to concentrate sunlight to 100 million times to reach this level.[2]

Put another way, if your fiber is about 1mm in diameter, you will need a perfect[3] mirror array 10 meters in diameter to drive it[4]. [CORRECTED from 400 meters, thanks to loup-vaillant]

Wild speculation follows:

• This has got to be used in pulsed mode. 100 kilowatts down a 1mm optical fiber is going to vaporize it if done for more than a tiny fraction of a second. Are there the optical equivalent of super conductors that are suitable for this?

• I went with a 1mm fiber because it "only" required a 10m mirror to drive it, but at what voltage are we going to get 100 kilowatts of power out of a non-conductor with a 1mm^2 cross section? Sounds like 50 zillion is the answer.

• Lets guess 10% efficiency, and the rest comes out as light at the end of the fiber (so our fiber doesn't turn to plasma). Where are you going to point that? I suppose into a light tight chamber contained in the molten salt loop of a steam power plant would be a good start.

• Maybe this all works better at the nano scale. Heat dissipation is easier since essentially all of the optical media can be in contact with heat sink. The mirrors get smaller to achieve the required light density. There is a shape, sort of stretched parabolic looking, that is a non-imaging optical funnel which might get your light all gathered to the same point, albeit going in a variety of direction. The total power would be lower, lowering the voltage required, letting you use sane power converters.

[1] And yet again, you have degraded the value of my undergraduate education by falsifying my hard learned facts.

[2] I may well have lost a zero or more each way. It's early. Don't use these calculations to place orders for mirrors.

[3] From 10+ meters away it is going to have to focus to a 1mm target. [CORRECTED from 200+, it doesn't sound so bad now]

[4] On proofreading I see I have a [4] footnote, in the text but no corresponding note. It was probably vaporized by a poorly aimed fiber.
