Why are those lights so big?

Indoor farms, especially in Japan, have been using LED lights for a while. Red/blue combos, in the pink/purple range, seem to work best.[1] The big advantage of LED lighting is not the reduced power consumption, but the reduced heat. The lamps can be closer to the plants without cooking them, which means the trays can be stacked closer and the density of the operation goes up. For most non-druggie applications, the plants aren't that tall. So small, distributed lighting units are used, instead of huge ceiling lamps.

Some plants can be overclocked. They do need a light/dark cycle, but it can be shorter than 24 hours. The life cycle of the plant is then sped up.

Network effects generally mean that the sort of work opportunities you see in SF or New York or Boston can't be spread around the country.

EDIT: Heck, industrial network effects of the sort you saw in Pittsburgh and Detroit and now see in Shenzhen can't be spread around either.

Give Pharo a try, I think you'd be pleasantly surprised.
Many people in power lie with impunity all the time, even though there's abundant evidence against those lies. No one seems to care.

Technology could have killed lies long ago. It didn't. Why would it start now?
We actually use the interchange revenue that would be going towards rewards points to pay for the costs of building/running the product. There may be enough left over to do a rewards program in the future, but for now the product is the points. :)
Yeah, it's interesting that right after the shutdown they said that they were closing it down merely to figure out how to operate without Victoria (what would they have done if she caught the flu?), not protesting. The shutdown was fairly brief (less than a day, it seems). Now days later they're coming back with, "eh, that thing we did a few days ago, it was also a protest." Doesn't seem terribly effective.
This situation is exacerbated by government cost of living increases which take location into account. (i.e. New Yorkers get bigger raises)

It is also a consequence of the lack of a quality passenger rail system.
As the saying goes, never attribute to malice what can be explained by incompetence.

In the case of United Airlines, be prepared to adjust your threshold of expected incompetence dramatically upward; since their merger with Continental multiple years ago, system-wide outages have been an every-couple-of-months thing.
The rope lights are especially cool for indoor hydro pole installations. Still, $1000 + 1$/day in electricity, it could grow let's say 100 kg of strawberries / year with that much light (that's an optimistic estimate), which would cost say 500$ to buy in a supermarket. That's not counting the cost of the rest of the installation, fertilizer etc. Could make sense at huge scale, but not for home sized installations, I think.
Thinking about it more the author did want RPC to die. Perhaps I only disagree with the implication that RESTful services are not correct. For the first half of the article that seemed the point, then a spontaneous bought of happiness at the end that events are happening the way they are. Now I think it was just a fluff piece with too much jargon.
Of course the data in storage or over the wire needs to be marshalled and unmarshalled (whether explicitly standardizing on a particular wire format or with header based hacks or whatnot). That's not the point.

The point is that a lot of the times, the two machines on either end of the wire need to agree on sizes of various fields you're sending (say in protocol headers). And then you want to work with that data internally in the code on either side. You better be absolutely sure how many bits you have in each type that you're allocating for these purposes.

And going even beyond that, very common, use case -- a lot of code reads cleaner and lends itself to debuggability when you know the exact sizes of the types you're using. It's not something reserved for just network programming.

The fact that death is random and sometimes widespread is selection pressure. Did you read to the end of my comment, where I said "less vulnerable to being wiped out by the odd plague or war"? Ever heard the phrase "don't put all your eggs in one basket"?

From the post, relevant to software design:

The key element in thinking like a physicist is being willing to push simultaneously to extreme levels of abstraction and specificity. This sounds paradoxical until you see it in action. Then it seems obvious. Abstraction means that you strip away inessential detail. Specificity means that you take very seriously the things that remain.

From "About Paul", relevant to network effects:

"Much of the texture and complexity of social progress is the result of a mismatch between stable social norms on the one hand, and the combination of continuously evolving technologies and continuously increasing scales of human interaction on the other. When technology changes and the scale of our interaction grows, our rules should change in parallel, but stable social norms can get in the way."

That suggestion is not really practical as you need to make the same requirement from all your third party libraries. While gcc will spend more time optimizing than go, the main reason for the speed difference at the moment IS unnecessary work done by the preprocessor because of the primitive importing.
We've done away with "Cultural fit" interviews at our company as we found they didn't actually do anything for us, maybe we just did them wrong?

Has anyone actually found a use for cultural fit? I mean its not like they help weed out jerks. If someone is a jerk they'll either be a jerk in all interviews or be on their best behavior until they're hired.

What should we be looking for in a cultural fit interview that isn't just "looks like us, works like us plays like us"?
> Or, was the Magnetar created during the nova?

Yes, it's a neutron star with an exceptionally strong magnetic field. Under the right conditions, a star collapsing into a neutron star can become a dynamo-like object. The magnetic field lines around a magnetar constantly twist and turn, and sometimes a large amount of energy builds up and ultimately gets released that way.

Magnetars are rare, mainly because they last only a very short time (a couple of thousands of years, we believe), after that they're pretty much ordinary neutron stars.

> What I'm wondering is, was the object a Magnetar, prior to the Supernova?

Stars do have pretty strong magnetic fields in general. This has nothing to do with magnetars, but consider that solar flares happen when plasma from the star gets trapped in magnetic loops that are then suddenly released.

It may be inaccurate, but it is hardly "lies." It is clear from the other verifiable quotations on your link that Thomas Jefferson would probably agree with the misquote anyway.
Just to be clear; it is a federal crime before you cross state lines too. It is just that the current administration has represented that it will not pursue federal charges for cannabis that follows stat law. The current, or next administration, could change its minds at anytime without any need for a vote or law or judicial decision. At that time, the DEA could arrest and a U.S. District Attorney could pursue charges. The Federal Court would be obligated to convict and individuals would be subject to Federal Punishment.

Until Federal Law changes, this is a real threat to cannabis users. Not to mention, the ATF could go after anyone that uses marijuana and possesses a firearm. The way the statutes are written, it is a federal crime to possess or use a firearm (even for sporting purposes) and be a consumer of cannabis.
Linode is good and simple if you have a not too large amount of nodes or complex need for extra bits, and I appreciate them for that.

I didn't really need anything shinier. Is it super-cloudy? Not so much, but also nice that you don't have to think about it.
bad communication - when mods email admins they are unlikely to ever be responded to. Victoria was the one point of contact within the admins that did respond to mods and try to resolve issues, other than her they were left to deal with issues themselves. SOmetimes that just wasnt possible. Honestly if you care look into some of the blackout threads plenty of mods will give you concrete examples of poor or non-existent communication, and we are not talking a mod of small subreddit with ~1000 subscribers, but reddits with 100k+ subscribers.
>Whatever you lose in the capability to lie for immediate personal merit you gain in the ability to stroke the political and emotional biases of people through distortion and disinformation in self-serving echo chambers that they have no desire to escape from.

Sorry, how did 'the ability to stroke the political and emotional biases of people through distortion and disinformation in self-serving echo chambers' not exist (and in even worse form) when you could lie?
I didn't know about this service but I'm not surprised. Seems from the site that they are catering to customers rather than restaurants. That would probably bring them into competition with Seamless. If I were going to order, I have no reason to check out DoorDash when most restaurants I'm interested in is on Seamless anyway.

Also seems expensive. People aren't used to paying for delivery and would much rather have that baked into the price. I think focusing on restaurants as customers would be a better strategy.
You could argue lots of long running server software has been compiled more times through development than it has been started in prod.
Yeah I hear you. I also like Assembly but feel they're missing some key features (although I haven't formalized them in my mind yet). You've sort of hit one of my major peeves with alot of these sites - they don't seem to have any good way to find/recruit projects based on domain interest. If you haven't already, it would help me a great deal if you filled out the survey. I'm trying to get as much info as possible before I start making something :)
Why is executing Java code in comments with certain Unicode characters allowed?
Actually, it's still entirely possible jgbond with apps that are being developed in the eco-system. Apps like Pointopia would still allow for exchanges and use of points...as the company would establish (I am a founder here and we have thought about this topic a bit and do consider this aspect)...http://www.paymentsleader.com/pointopia-rewards/
1) I don't think anyone else than Ryanair does that. I do agree they suck though.

2) It is an American issue. Have you been on any airline from Europe, Middle East or Asia? If you generalise the offerings and compare the level of service then you will find that American airlines offers much lower service. Most European airlines are quite good, and most big carriers from Asia and Middle East are much better.

Yeah, no..
Gruez meant the actual IP(v6) address.

@gruez, The length of an IPv4 address would not allow for a future-proof-enough address length. IPv6 might just do it, I can't say.

@y0ghur7_xxx, Let's say I want to expose some snow-unaware service via snow to only a single host. I have no way to set up an iptables rule to do that atm. "When you resolve a key name an address is assigned to that key. The address remains assigned to the key as long as there is traffic, but never for less time than the TTL on the DNS record and never for less than 5 minutes (and generally for much longer than that)."
The availability of the truth has had very little impact on what people choose to believe.

To me, this seems like a positive. Microsoft is infamous for acquiring and keeping bloat, and its one of the things that has traditionally knocked them out of the spotlight. With this kind of restructuring, it gives Microsoft a chance to make their business and strategy right - even if its the second or third try doing so.

It really depends on your timeframe, skill needs, and how desperate you are. Some jobs absolutely require you to be productive on day 1, while others are less stringent. In the latter case, hiring for experience and not just immediate skillset makes sense.
SCOTUS has demonstrated, as I pointed to in Raich, a willingness to engage in staggering contortions to reach/justify/support a goal. Accepting your reasoning, however correct it may (or may not) be, would mean massive changes in what constitutes contraband and how it may be suppressed - a degree of change SCOTUS is rarely willing to cause (and certainly not over cannabis).

Your reasoning has been tried, and failed. People are working very hard to make such reasoning work, and are making little progress.
I'm not confident that it's much easier in any universal sense, but I certainly agree that the nature of at least the presentation of an algorithm defines the easiest way to talk about its analysis.
I spent fifteen years scripting on Unix for a living. I consider powershell to be garbage. Lack of 'separation of data/presentation' is what made unix ubiquitous. It's also what made HTML ubiquitous. I think it's great that powershell is getting full, native ssh support -- because then I can manage windows computers in a non-ridiculous way, regardless of what PL wankery Microsoft shoved into the syntax.
I have a possible diagnosis- Technical debt has reached critical mass!
I think that's the point. Without lying, political and social structures of humans break down.

Lying is literally what enables us to work and live together. Even something as simple as telling a friend or coworker that that thing they do isn't that annoying counts as lying.
I hate it when I solve programming problems while sleeping. It makes me feel like I'm working for free on my time off. They're only supposed to be renting my brain for part of the day.

You're probably right. The book I mentioned is the one I see most frequently recommended as a how-to guide to mindfulness. I have not read Mindfulness in Plain English, but judging by the title it sounds like a similar approach.
If you follow the one of the links in the story, you'll see that one of the reasons the housing prices in NYC and SF are so high is the unwillingness of current residents to allow more construction to allow greater housing density. So, in this case, it isn't a proxy for population density since the high prices are actually a symptom of below-optimal population density.
Regarding misspelled identifiers, I've experienced the exact opposite problem. Code I had to work with that was clearly written in simple editors often contained misspelled words (though it was also usually written by non-native English speakers) and even bugs arising from using a wrong variable name. Errors that with proper tooling would be near impossible to make, because the tool would immediately underline the variable as either containing a spelling error or not being defined. Not to mention it also lead people to using generic non-descriptive variable names and abbreviations.

I also watched some people trying to printf-debug a problem, and it's usually a fest of "Was the problem here? Hm, not here, ok, let's put these statements over there. Hm, not over there either, what about here... (repeat several more times, depending on how deep the calls go)" Having to do something like this would really feel like stone age to me, when you could just get all the relevant information in one quick pass without having to modify any code.

Another thing is documentation. When you know that you can just bring up a method's documentation with a single keystroke, you are much more motivated to document your own methods in the same way. If it's just "some generator will create a bunch of static html pages later on that most people likely won't ever read", some people will not bother.

I do agree about flaws in tools being a huge issue though. Especially with refactoring tools, if you can't trust it to not accidentally mess up parts of your code, you might as well not use it at all. Similarly, if you can't trust a "find usages of this method" to find ALL of its usages, the utility diminishes severely.

EDIT: oh, and perhaps the most simple, but most important feature of all, being able to Ctrl+click a function to navigate to its definition means that people are going to dive into the code a lot more often, even framework/library code, which is obviously beneficial to learning how things work under the hood. The less friction there is to doing something, the more readily people are going to do it.
Following your line of arguing (based on your characterization of the SC's logic), all activities can likely be shown to fall under the purview of federal law and federal law enforcement agencies as essentially all activities affect your local environment, and in turn all activities that interact with your local environment, which will include many activities directly or indirectly impacting commerce which will then impact interstate commerce.

This line of argument can be used to justify federal involvement in anything. This makes it useless in drawing any interesting distinction, nor does it address any of my original arguments.
I love OpenBSD, I've purchased CD sets and made (small) donations, but they've been in financial crisis for as long as I can remember -- at least 2006. The truth is that it's entirely OpenBSD's fault; from the beginning, their attitude has been, "we'll just produce a lot of high quality code, and fix other people's bugs, and people should then donate to us out of good conscience."

And that doesn't work.

They've been openly hostile to projects like pfsense (or maybe it was Comixwall, I don't remember) and they've repeatedly declined to do anything that might bring more money into the project if it required even the slightest distraction from any of the principals of OpenBSD development.

The sucky practical reality is that "hoping enough people care" isn't a really smart way to ensure financial security for a project.
Part of me wonders why they don't open source datomic and crank up the marketing effort on the consultancy and datomic/clojure/etc support portion of the business. It seems like a much more effective model for DB companies. For direct revenue streams, they can always have tuned/monitored clusters packaged as appliances.
Or the bitter experience of an old, cynical, object oriented programmer.
I've switched from DO to Vultr back when DO did not offer FreeBSD and DO's SFO network was pretty bad. I'm back on DO now because I've got my hands on some credits, but I would switch back to Vultr when I run out. DO's SFO network has improved I think, but for the $5 plan you get 50% more memory at Vultr (512mb vs 768mb).
Tldr:

When we sleep, our brains process the events of the day and pick out things to stow away in our long term memory.

Maybe as a side-effect of this processing, they also aid problem solving - after a good night's sleep, you are able to find solutions to the previous day's problems faster (than you would, if you hadn't had the sleep).

As we sleep, our brains clear away toxins that accumulate during our awake time. These toxins may be culprits behind neuro degenerative diseases.

There seems to be a correlation between sleep deprivation and cardiovascular diseases.
So the article talks about how technology is making it harder to lie which I think in some ways it's true but in others it's making it easier to bend the truth and sometimes it even makes it easier to lie. For instance many of the folks that are against vaccinations will regularly quote "studies" that are published in "journals" that are all made up to sell someone a book or some natural remedies. Even worse is all of the information out there about GMOs with some of it being good science, some bad and some places where they mix it all up. Of course a normal person who didn't grow up to become a scientist isn't going to be able to separate between all of the good and bad information every time (especially since even scientists themselves can't always separate it if it's in a different field).

I have to wonder if an ultimate goal will end up being similar to Peter F Hamilton's Gia Field idea in his books where it essentially links people together in a way that's not easy to break and it forces you to feel everyone's emotions around you. So if you are trying to lie to someone, hurt them or steal their stuff it's going to be obvious not only to the victim but everyone around you and the perpetrator will feel his victim's emotions. Naturally this is a pretty crazy idea that's probably over 100 years away from being able to happen but still the article kinda reminded me of it.

Technology won't kill lying. Despite there are clear and distinct punishments in society for those who murder, people still don't resist their impulses or think they're can out smart the system (some do, some don't).

Technology will never stop those who have retaliatory power from lying. Janitor catches CEO lying about making a specific sales deal go through versus CEO catching janitor lying about when he clocked in. Strong intra-team asymmetries exist.
