There are a couple of things everyone should know when it comes to energy production:

1) Energy investment is primarily driven by cost, not perceived/actual safety. Safety regulations do affect cost, but not enough to significantly change investment (at least in the US, with the current conditions).

2) Base load power and intermittent (e.g. solar/wind) power are not the same thing, and are not comparable. The concept that "solar and wind will save us all" by themselves is fundamentally incorrect, and actually they make things worse in many ways.

Nuclear fear mongering has resulted in high levels of regulations around nuclear power, but even without that natural gas has an edge in $/kWh. There just hasn't been demand to build nuclear. On top of that, nuclear needs to run 24/7 to amortize high capital costs. With solar/wind, there is high variability in grid supply, so nuclear is significantly less cost effective, and is getting phased out in favor of low-capex plants (i.e. natural gas).

Barring some energy storage miracle, we'll eventually end up with ~35% renewables, 15% hydro, 50% natural gas in the US, with HVDC interconnect. No nuclear, no coal.

I'll add that the drivers (on all platforms) have really turned around in the last few years - for the better. Crossfire support is still terrible compared to SLI, but that is a small demographic.

Indeed. Already seeing car insurance being based on age and gender. Because apparently young male drivers are more careless and aggressive in their driving style...
Hi, I'm Dominik, co-founder of Husarion.

Together with my team, we have been developing a fast prototyping platform for robots, for almost 4 years. There are many generic prototyping platforms for hardware projects like Arduino, or RaspberryPi, but we think that by focusing on robotics, we can deliver a product that will allow our clients to iterate their ideas much faster.

We are very excited because we have launched the second generation of our product at Crowd Supply.

It would be great if you could tell us what you think. Thanks!
You've given some toy examples, but in the real world you're writing custom decoders. For example, when interoperating with any API that you didn't write.

Your example would lead us to believe that nobody is writing custom decoders in Haskell that look like Elm's decoders, and that's... very misleading.

Sure, mine had BSOD's space bar double-tap, choppy sound and laggy 3D mouse (I mean 1 sec lag) right out of the box. I wasn't as patient as you, I sent it back. On Linux most was fine except the keyboard, but I was too afraid that HW was crap (also, searching for solutions was throwing me a lot of other people's issues with the HW). It seems like I was right.
Yes i am sure about that.

"CS lecturers not allowed to be paid more because positions are harder to fill vs say Fine Art History lecturers"

Why does this sound backwards to me? If a position is hard to fill, wouldn't you want to pay the person more so that they don't leave?

Conversely, if a position is easy to fill, wouldn't the university pay less, since if the person leaves they'll be easy to replace?

How does paying someone less because their position is hard to fill make any kind of sense? What am I missing here?
Two TDPs, depending on if it's air cooled or liquid cooled. Seems to be 300/375 respectively.
> You could just have pre-printed ballots with the name of the person you're voting for on them.

Imagine a ballot (or something) that had the pre-printed names on them something like those paper "call me for xyz" things you see on bulletin boards everywhere (or well you used to)?

Basically the names would be on pieces of paper (maybe with a QR code?) about the size of what you get in a fortune cookie, that can be tore off the "ballot" and dropped in a box for later counting. With a QR code (or something similar), the counting could even be done with a machine.

Such a paper ballot could arguably have many names attached (here in the US we have so many positions and votes to cast on so many things it's mind boggling, especially during certain election times). I'm not sure if or how well it would work, but I think it might be doable - at least enough to attempt.
Seems like most of his advice could be summed up as: "Don't over-complicate the situation".

To use his first example, when he's being insulted why spin off into emotional-analysis neverland? What's happening there is you're being abused by an asshole, and you should respond to said abuse and, once that situation is resolved, examine the real issue more thoroughly.

I'm speaking as someone who used to think exactly like this guy. What I realized in early college was: In general, no one cares. No one cares if you're partially wrong, no one cares if you're a little off or awkward, no one beyond your family/SO and close friends gives a flying fuck about your emotions. Nor will they remember a slight moment of awkwardness a week later. They're simply far too consumed with their own lives for it to matter. Demanding perfect social interactions is paralyzing, irrational and not expected.

He does arrive at some appropriate conclusions ("Know thy worth"), but all the analogies and self-analysis he does isn't "emotional processing", it's simple insecurity. IMO the only emotions he's processing in those moments are fear and anxiety.
Before we even get to the safety, and the disposal of the nuclear waste, we have huge difficulties with the basic economics and construction of nuclear in the US.

The two plants under construction, Summer and Vogtle, have been plagued by construction difficulties and cost overruns. The Summer plant was just finally cancelled today. It seems that the Vogtle plant is going to follow the same route.

The management competence and institutional knowledge needed to build these large, insanely expensive projects seems to have disappeared. The time for nuclear in the US is done. Other options are cheaper, faster, and more responsive. And that's ignoring the political aspect of it all.

That's like saying an angry bear has many of the benefits of a bicycle. It may be factually true but the downsides of riding an angry generally outweigh the benefits, and anyway it's a different kind of thing altogether from a bicycle.
People seeing it differently does not mean they are rational actors.

That said, this kind of risk response might be an evolutionary adaption. Better have a threat that slowly kills individual members of the tribe (allows escape or replacement of losses) than something that is outside your control to respond to and wipes the whole tribe.

No.

Modern reactor designs are actually designed in a way that makes it difficult to maintain the reaction. If you are not actively maintaining it, then it will stop on its own. This is opposed to the most common existing designs, where you need to expend effort to _stop_ the reaction.

This is not to say that they cannot fail in some novel ways.

Well, the other obvious reason is if everyone can achieve "good" for 1k, everyone will make the investment, leverage the asset, and the ROI will disappear because it was easy & accessible to everyone and becomes highly competitive.

Bitcoin mining was a good example. Everyone has a graphics card, and mining was pretty trivial. Great example of a cheap capital asset with low effort to monetize. Quickly, the ROI slimmed until only large scale operations with low costs and good economies of scale were profitable.
I assume the university has a policy in place that all lecturers are to be paid the same. And the original commenter was alluding to this precisely because it is backwards.

The recalcitrant problem of nuclear waste storage is now a permanent part of human history going forward even if not one single nuke plant is ever onlined again. So the dangers of nukes are here to stay no matter what. Making a new nuke plant or not will not change this problem. One could even argue that if we continue developing nuke plants we'll get better at dealing with the waste. If we don't we'll get worse.

Having said that, it takes 30 years to online a new nuke plant. They have to be maintained over centuries. It's easier to make wind farms, geothermal and photovoltaics today, right now. We can't wait 30+ years for nukes to help our clean energy future happen.
I think it's worthwhile to differentiate between a critical mass fission/fusion bomb and a dirty bomb. A dirty bomb can be made from anything radioactive coupled with a conventional explosive, since the goal is just to spread the radioactive material as widely as possible. Fission/fusion bombs (what we typically would consider as "atomic bombs") are, as you said, way harder to pull off. The general public definitely likes to conflate the two.

There are many services printing metal parts. Shapeways has been doing it since 2009. There are several workable processes. [1][2] This new machine competes with the ExOne Innovent.[3] That uses a single-step process (no oven needed) but is slower.

Desktop Metal's big claim is that they can lay down "up to" 8200 cm³/hr of metal. The "up to" weasel words are a problem. They're vague about the layer thickness. 3D printing has a basic trade-off between speed and precision. Most of the commercial vendors go for high enough precision that you can make working parts. Desktop Metal doesn't offer many pictures of their finished parts, but I did find one.[4] That looks like it was made with layers of about 0.5mm. The furnace step provides some surface smoothing. That's not bad for casting.

It's nice, but it's not clear that it's 100x, or even 10x, better than the competition.

Most people don't go to running clinics, because there's no obvious reason to assume that you need to be taught how to do something that you've been doing just fine since you were three. It's extremely counterintuitive, and I don't think you can really blame most people for getting it wrong.

Agree in general that Elm is nicer than Redux. However...

>>> You don't have to transpile or add a linter, or a type checker, or stitch new libraries every few months because the trend changed.

Elm is still in alpha, and is adding and removing breaking features all the time. (See ports for example) [1]

>>> No webpack or babel or eslint or immutable.js or typescript or flow or any of those.

If you are integrating elm into any kind of existing application, you will likely need webpack. [2]

>>> I doubt that learning "redux-sagas" will help me a year from now.

Given redux is an order of magnitude more popular than Elm is, and Redux Saga is the most popular effects handler library for Redux, I would not agree with this statement. Learning about generators is valuable regardless.

You make it sound like those hacker movies where the bad guys have free access to networks and no security protocol around this.

Voting machines in the us isn't easy compared to that at all. Irans security protocols are easy.

As long as there is a paper trail you can't just hack the US election EVEN if you got into hacking the machine which is extremely unlikely. Unless you convinced thousands of people to be in on your scheme. It won't happen.
High speed rail pretty much only works in Japan and Europe for this very reason.

My guess is that you don't intend to be insensitive, but the awareness you're demonstrating here shows a lack of empathy and true understanding/acceptance of the emotional sensitivities to others, particularly this author. To minimize someone's emotional state/response isn't only insensitive (intended or not), it's also abrasive. I'd imagine it's also likely causing problems for you in other areas of your life, if you look and/or solicit candid feedback from people around you that aren't quite like you are.

If you're (or anyone else) interested in talking more about it, feel free to let me know. I had to do a lot of similar work starting from a similar place as you're describing. You (and anyone else seeing nothing "wrong" with the author's response) might also consider reading Karla McLaren's _The_Language_of_Emotions_.
Found some coverage that wasn't just copy-pasted between blogs.

https://www.livescience.com/53591-millennials-dislike-narcis...

Still couldn't find the studies themselves though.

I wonder if there's any way to the effect of age, as opposed to generation, on the studies. Even in the livescience coverage I wonder if the trend is more recent generations are more entitled than older generations in general (as the submission posits) or if populations become less entitled as they age and if so how entitled were the older generations when they were the younger generations' age?

Not something a doctor can do, but Healthcare can. By making the process faster shorten the period of uncertainty. Partly by optimizing the way data is and can be shared, you would be surprised how hard that is even within a single hospital, much worse with multiple or country/state boundaries. Next, digitize and automate using NN and deep learning reducing the burden on doctors allowing them to run more cases a day. We can further reduce the time period case by optimizing reporting, especially for a regular 2 minute case they spend most time on filling the report. Much of which can be automatically filled.

If we cut all these times you could get a diagnose much faster than 2 weeks.

Of course next step is to monitor every day so we detect before cancer actually manifests. Start treatment so early it never gets a chance. Using all sorts of monitoring. Wristbands are the proof of concept, but in say 10 years that will mature and maybe we get a constant monitoring realtime watched by a digital MD watchdog. Who knows.

Where is github hosted?

Do they use AWS or another commercial cloud provider, or do they have their own servers in data centers (hopefully scattered around the globe)?

If AWS, are their services spread among multiple availability groups? I'm just wondering how this could happen.
Most people who I've talked to about their fears over nuclear energy say they wouldn't want to be in the blast zone in case of a meltdown or near a potential terrorist target. Then I pull up the map of existing nuclear plants and more often than not they already live close to one. I've found its a fear thing for most people.

> Depending on the nature of the part, it might be necessary to do some post-print surface finishing like sanding or bead blasting to smooth out the layered
surfaces

If this is anything like the powder-bed parts I've handled, the layers are going to be pretty rough. I wouldn't be surprised if they need some degree of post-machining. Don't sell your CNC mill just yet.

Furthermore, 15% shrinkage during sintering? What's the dimensional tolerance on the finished part then? I'm guessing it's not great.
Not all, but many. Particularly metals that would likely be used for printing applications, e.g., iron and aluminum.

However a ton of materials are explosive if made into a fine powder then dispersed, so this is more of a general fabrication issue, than something unique to 3D printing.

Only AMD can really say whether Vega turns out to be a failure or not. We don't know what their goals or constraints were. In the end, if it has a performance/price advantage over Nvidia's (year-old) offerings, then it will be at least a relative "success" from a consumer pov.

It seems to be bringing some technological advancement too - using GPU memory as a cache seems like the way forward. Naive calculation gives me a couple of MB to store a single 1080x1920 texture. Current game usage is approx 1000 times that. It takes more than one texture to build a scene, but there seem to be gains if more textures are loaded on-demand (or slightly earlier).
Should HN have an employer field next to user names, like the domain field next to the article name? It may have helped with the recent Docker issue.
They can afford to pay those who negotiate closer to their true value (often still significantly less) is because they pay the vast majority of people less.

The only way transparent salaries help the majority instead of being used as a tool for businesses to just say, "We only pay 100k/yr, that's what everyone makes" is if there is some body enforcing fair pay.
