The one I attended assumed their students have spent a good amount of time trying to learn on their own. They also had a long list of work to be read and done before the program even started.

In my limited experience, the ones that struggled most were the ones who simply didn't do the prework that was asked of them. Some people think education is something that will happen to them if they pay somebody enough, compared to those that went to a boot camp to accelerate the self-education they had already started.
Aren't there long stretches of time where the nanoreplicators just do their thing and all you can do is watch and/or get another cup of space coffee? (somewhat like the computer program compiling processes on earth)

Or are you guys capable of slowing your perception of time so it seems to go really fast?
I just visited https://www.bobbarker.com/

This is a company that basically makes products of the lowest quality for the cheapest amount possible. An $800 3D printer I've used created higher quality items.

If you want a real laugh, check out the "Mission and values" section of their website. SPOILER: it has by far the least amount of content
There are at least some cases where the expect functionality is either required, or makes things much easier.

I know expect, or expect-like functionality is used often for automating things across groups of Cisco devices, for example. Where you need to process the output of one command to drive another, or where commands have a separate "commit" Y/N type prompt.

Outside of that, most of what this describes feels like something I would do with Ansible.

The inner shells need to be thicker for three reasons - photon pressure, they are at a higher temperature, and the wavelengths they are capturing are shorter. Having said this they would not need to be much thicker than the outer layers.
I expect there are logistical reasons that make it more cost effective to expand within the continental US for now.
> the costs don't seem worth the benefits, especially without some other form of energy to supplement the 650x increase in energy needs.

That's assuming the larger surface area is undesired, and the extra space won't be utilized for something else, like habitation, or storage.
We tend to assume that one would want to be able to walk and live inside a 1AU Dyson sphere, so structurally it would have to be sufficiently strong to support such uses.
What atoms - when arranged in a single-atom-thickness structure - could collect, transform, and transfer radiant energy back towards the inner shells, while also remaining rigid enough to not deform under the pressure of that radiant energy (not to mention the energy emitted by other stellar phenomena)?

For better or worse, we have to assume the alien civilizations have the same physics that we do, otherwise the civilization simply has to build their 1au sphere out of artificially created unobtainium to achieve 99% efficiency.
If the bank does say fuck you, I'd file a complaint. If they still say fuck you, I'll reach out to the financial ombudsman service. And if they still say fuck you after that, I'll take them to small claims court.

What do you expect me to do? Investigate the matter myself? Buy myself an unlicensed firearm and look for the hacker to get it back at gunpoint?
The article posits that maybe advanced alien civilizations may be motivated to build larger (and hence harder to to detect) Dyson spheres for the efficiency gains. While that's a possibility, it's also possible that being harder to detect is an end unto itself for safety reasons.
Discrimination is exactly why you want to leave that decision in the hands of HR. In the event of a lawsuit they'll have evidence to show that they followed the process your lawyers signed off upon and the decision to say "no hire" was based solely on permissible factors. At large companies, this will go as far as "here's a database dump of all the applicants with X on their criminal record... as you can see, we didn't hire any of them".

As soon as individual managers want to make those decisions for themselves, it becomes much harder to refute claims of discrimination.
People are often scared of testing their business ideas. Having this awesome idea of something that "might" work is a lot more pleasant than learning if it actually does. Most ideas fail right out of the gate - even the ideas of people who've had previous success. When I, or one my friends is excited enough to work on an idea, then the actual execution of the test is the easy part.

There does seem to be some opportunity to inject common sense in there though. How common, for example, is a $100/week in-app purchase? Seems like there's some threshold that should kick off a review automatically.
Over the last several years I stumbled into a killer app for robotics: testing. Almost every manufacturer of any thing has a secret testing lab of robots (and engineers to program them). Robotics are good for dealing with dangerous things (like welding or bomb disposal) and those bots get most of the attention. But robots are also great for "boring", tedious things, like tapping buttons for 12 hours straight. Yet those robots don't get as much attention because, well, watching button tapping is slightly boring, and more importantly, many companies want to keep their quality control (and manufacturing) robotic processes a trade secret. Thus, most people have no idea how prevalent robots really are beyond flashy Boston Dynamics videos.

So there is no confusion, I'm not making a arguement out of thin air, this is the case law.

Here is a decent article [1]published by the American Bar Association regarding the resale of "genuine" goods (not counterfeit) by unauthorized retailers. Skip to the "warranty policy and unauthorized dealer page" section, then "going to court".

Note the exceptions to first sale doctrine include "material changes" to the trademark good, including non physical changes, then does a decent job of listing those changes recorgnized by the courts.

Edit: from article regarding non-physical changes to trademark product, "Perhaps most commonly, differences in warranty protection coverage between authorized and unauthorized sales often lead to trademark infringement"
Doesn't this also assume a computer similar to our own? How would this principle apply to a biological computer for example?
You could be right as long as there is no monopoly or oligopoly.

However, in capitalism money agglutinates, and thus it has a natural tendency into this direction.

Also don't forget that capitalism works until it doesn't, at which point a revolution may take place, and then anything can happen.

We have created sub-universes with different laws of physics etc. When we get bored, we inject ourselves into the viewpoints of entities in those universes, after temporarily wiping memories of our true selves so we can re-exist as lesser, mortal beings.

Thanks for pointing it out. That is certainly a possibility given the ambiguity in the announcement. In fact, it's not even clear at this time whether wiping production was intentional or not.

I've heard stories where employees wiped production by accident and promptly became ex-employees, followed by their ex-employer trying to put all blame on them. We don't have enough information at this time to determine whether this is what happened at Verelox.

I run an office design website and have a bit of experience with this type of thing.

Often architecture and design firms aren't interested in answering questions about products on Houzz because the people asking for the information will almost certainly never be a client of theirs. Plus depending on the size of firm, they aren't staffed to sit around answering questions from random people online.

In addition, it is often the case that the products used in custom homes or projects can't be sourced and purchased easily online which makes it difficult to earn any sort of affiliate revenue. This is likely why many photos on Houzz show similar products but not the exact product.
Ask HN: Hacking your flow state. How do you get in 'the zone'?
I've had this idea for a project I want to complete in my spare time (as part of my hobby). It involves small bits of coding, but not too much. Actually the vast bulk of it will be arranging bits of unstructured data into something more manageable and digestible, and doing a lot of organizing.

But one problem I'm having is how to get into the right state for this. I've read various articles online which address the issue of state: advice like have a cup of coffee beforehand, clean your workspace, write a clear outline of what needs to be done, etc

But I've tried all these and still can't stay focused. I probably have some mild form of ADD brought on by excessive scrolling through Twitter and whilst caffeine is nice, it only makes me jittery and makes me feel like I'm getting work done, but when measured, it's no different than being off caffeine, or 'sober'.

Are there any other tips besides the ones constantly being churned out online in articles on how to get in the zone and perform brilliant work? What hacks do you use to get in a flow state and do really focused work?
Just for some scale, we have 4k+ engineering employees and if we were a public company, we'd be somewhere around the 5th largest software company in the world by revenue. (Strange stat, but our primary product is software and accounts for over 3/4 revenue)

Given that software systems are at their heart gate configurations on silicon, and given that those gates need to interact with mechanical and electrical systems, there will always be different classes of recoverable error for which the recovery procedure differs.

So yes, outside of pure functions you will always need special-snowflake error handling.

You only write it once in your Database class. The only thing that changes from call to call is the query string and parameters. Handle all errors gracefully there, throw an error to the calling code and let it handle it to the user with a 500 while the support channel gets alerted with the real error.
> Most employers will never truly respect their employees, ever, under any circumstances. Employees aren't people, they're a "human resource", a cog in the corporate machine as interchangeable as any hardware. More so, in fact - a piece of machinery would be hired on a fixed-term lease, but most employees can be dismissed at will.

> I don't endorse vandalism, but I think that it's utterly naive to expect that you can earn the respect or loyalty of corporate America. It doesn't matter how honest you are or how hard you work, you'll still be discarded like an oily rag if you're surplus to requirements. You'll still be lowballed on every pay rise while executives and shareholders make record earnings.

You are absolutely correct about corporate America, the executives, and the shareholders. The hard thing is that you can earn the respect and loyalty of the other cogs that you work with, which can be difficult to disentangle from that underlying truth.
As someone researching whether to use Fabric or another option, I do not have to wrestle with the sunk cost fallacy. I'd be interested to hear how the features they share compare to each other objectively.
An idea, an AGI stack
Why would you be running on dozens of distros on different architectures?

With some sane level of standardization (lets say less than 6 combinations) it's easy enough to test all and fix up the discrepencies.

The more declaritive you are, and the less you assume about the environment, the better this will work.

Ie. if you need a package, always install it. On some distros it may be there by default, but you'll run into issues if it's not. The good thing about being declaritive is that there's no harm in checking.
The idea that a big government will bring about decentralization is laughable.

Thank you for your honesty at the interview. We really need more people to point out to people in management that some ideas are just stupid and simply should not be done.
This looks very interesting from a regulation point of view, as a potential way to bring greedy self-interest into alignment with national/international social interest. I wonder what scenarios could be given a "pest tax", to alter the dynamic from a tradgedy of the commons to a cooperative/competitive optimum?

the profusion of posted slides on the internet is a detriment to researchers everywhere. so many times i've googled something technical (CS, math, engineering) and what percolates to the top are lecture slides, which are almost useless for actual in depth learning.

Yeah, Python is way, way better for text. And I say that as a long-time R user. R really doesn't like things that can't be represented as datasets.
Hey HN, I wrote this post. I'm getting the sense that not a lot of commenters are taking the time to read the contents before reacting to the title, so I'll share a little spoiler/TL;DR:

Good boilerplate is boilerplate that usually gets changed over time (and in different ways each time) as we iterate over the code.

It took me a while to come to this realization (and I explain the reasoning and consequences in the post), so I hope it's helpful to other people who might not have found this intuitively obvious.

Also perhaps "terse" or "clever" are not the best words to describe the counterpoint—I welcome edit suggestions.
Also for context: Just because an alternative is worse or "just as bad" doesn't mean that the status quo is okay. The United States is fucked up in many ways, regardless of the fact that Somalia has had it much worse.
No. Is the react rendering engine rendered by Html5 Canvas or WebGL? That would be the closest analogue.

In WPF you can get direct access to their retained mode graphics system, built on top of direct x, and ignore XAML completely.

Before making a claim like "React is what WPF should have been", the author should have done a lot more research into what WPF is and what could be done with it. The beauty of WPF isn't in XAML, it is in WPF's underlying framework and rendering engine. XAML is WPF's training wheels.
>> Urbanization fundamentally has been engineered to create "wage slaves"

> Suppose someone was born out in the forest, and there were no cities, no societies, no technology. Would you call that person a sustenance slave? Would you say that their foraging was involuntary?

No, they are not a slave because they have no master except nature.

A wage slave has at least one master: his boss and the system that forces him to work for one.
I think you are mixing up multiple things here.

Improved agriculture required fewer people to generate the same amount of food. We were lucky that industrialization happened at around the same time and could provide work for the displaced farm workers. There isn't any guarantee that some new type of labour-intensive job will be invented just at the point that AI becomes widespread.

I don't see how co-operatives help if there isn't any demand for their output.
I find it interesting they put Albania into Persia, not between Dalmatia and Macedonia/Lepirum Novum.
Some of it is just documentation and marketing. If you go to the AWS api gateway main page, it talks about serverless/lambda integration right there. They also have specific pages that show how to use them together. Including using them as the endpoint, or using them at a higher level to influence routing to a different endpoint, or modify requests, etc.

Contrast with Google, you start with the confusion that there are two products (cloud endpoints, apigee), and neither really talks about integration with Cloud functions.
Totally agree. I took one semester of Judo in college 20 years ago. Since I've fallen four times on asphalt, and miracuously, each time I somehow turned it into a roll and popped back up on my feet. The few that see it think this middle-aged guy just decided to do a crazy sommersault (in odd circumstances). I felt like I had a superpower :)
> IMO, the ease of manipulating Lisp code comes from that code being internally represented as a tree.

I don't think this is sufficient to explain the ease of manipulating Lisp code, After all, most languages are processed through an internal tree representation. (This fact is inherent to the grammars used to specify and parse those languages.) The only real exceptions I can come up with are concatenative languages like Forth, PostScript, and RPL and in these cases the syntax is truly primordial. (Which also carries its own advantages.)

Where Lisp's s-expressions both shine and suffer is that they bring the structure of the initial syntax tree right up to the textual surface of the language. With some exceptions (like the quote syntax you mention), there are syntactic textual delimiters at either end of a Lisp ASP node, which is not even usually the case in an infix language.

Just to illustrate, take these two (hopefully!) equivalent expressions... one in infix and the other in an s-expression.

(> (+ x (* 2 z)) (- y 3 u))

x + 2 * z > y - 3 - u

Given those two, and an editor command that selects a sub-expression or broadens a selection to include the enclosing sub-expression, where is it more obvious where the sub-expressions begin and end? The parenthesis in Lisp clearly delimit the nodes.... which makes it easier to identify the tree structure at a glance.
Of course, it also makes it less-usual for human readers, who are well trained in infix. (Although I should point out that reading the infix requires being aware of hidden precedence and associtivity rules for the operators in use.... which is often managed by conventionally requiring extra parens, etc.)

This is the trade-off I was referring to.

From a couple posts down:

> At this point we're basically both making unsubstantiated assertions.
Anecdotally, I know that I was able to learn to read C, Pascal, BASIC etc... A proper way to resolve this question would be to have a controlled study where a bunch of people not previously exposed to any language is given a crash course in, say, S-exprs and JSON, and then asked various data retrieval tasks on input of increasing complexity.

The way this is written almost implies that there is a single continuum on which these syntaxes can be ranked into better and worse. I really think this is something that's much more subject to opinion and personal point of view than that. As positive as you've been about infix syntax, I can state that, for me, the prefix syntax tends to feel more right.

In other words, I don't think this is as much either/or as it is both approaches have strengths and weaknesses.

I hope that wasn't quite what I said :)

I said, IIRC, that they're very similar in terms of results and GRUs are a little simpler. I've seen some papers show better results for GRU, and visa versa.
You make a good point.

I did a survey of national and local monopolies a while back, and I couldn't find many sustained ones (in the US) that weren't sponsored by the state.

Oligopoly is another matter entirely.

> Also don't forget that capitalism works until it doesn't, at which point a revolution may take place, and then anything can happen.

Revolution may occur when the peasants feel injustice hard enough (the starvation poverty kind - not the poorer than Bill Gates kind) - but are there any examples of this happening in a more-or-less Laissez-faire market system? [I seriously don't know - could well have been]. Do you think that (for example, in the US) that we have enough mass of discontent to build up revolutionary momentum, given that the poor are (on average) fat, dumb and happy? For example, the driving force behind the French Revolution wasn't simply that people wanted social justice (although they wanted that too), but that they were hungry. And, in Venezuela, where there may be revolution soon (or simply escape), it isn't driven by a paradise of low-priced veggie options at every supermarket supplied by capitalism - it's desperation driven by hunger caused by extreme corruption that have gutted the country in the name of equality.

For myself (and I realize that opinions vary), if the government keeps a light hand on making sure that people don't lie, cheat and steal as people engage in day-to-day commerce in the marketplace (as humans are wont to do - we like to trade, it seems), that generates "plenty" -- which we have seen from the kingdom of Lydia to the present day.
