Thanks for these points, bcheung! Here are my thoughts on each point:

1) The sand-based system is based on Dr. McMurtry's aquaponics research at NC State University. Here are a list of publications about it: http://iavs.info/publications/ In general, coarse sand is a great substrate for plants. Both research and my own experience show no problems with aeration or anaerobic zones forming when set up correctly.

2) The timers are really no more complex than the pumps, so I really don't see them as adding that much complexity.

3) The way the water drains through the sand means it keeps dripping and agitating the surface for several hours after the pump stops pumping water to the vegetable beds. Of course, if you plan on maxing out the stocking density, you should add bubblers.

4) Because the water starts trickling through the sand seconds after the pump starts, you only have ~10-15% difference in water height.

5) If you want to eat the fish, might as well try to eliminate anything that might get into the fish through the plastic. It doesn't add that much cost.

6) That's a good idea, but adds the requirement of finding pure ammonia available for sale.

7 and 8) I think most people will just add filtered tap water and go with whatever pH that is.

One of my favorite memories of David was how he got grumpy about being best known for that term paper. He had done much more.

French culture has some inconsistent, fascist, illiberalisms, especially in the differences of making fun of Christianity vs. making fun of Judaism, or similarly with Christianity vs. Islam. (govt demanding firing of Sine). Actual progressive liberalism should at least include listening to other viewpoints, being open to new ideas and generally being sensible and constructive. But narrow, identity-politics labels aren't all that useful in reality and end up inventing wedge-issues and false dichotomies. (There are some people looking for common ground while others are looking for Sayre's law fights.)

The US Army typically rotates positions every 2-3 years, sounds basically the same. The Civilian world is actually catching up to this concept, "externing" is the new buzzword.

If you've learned how to thrive in a bureaucratic environment like the military, you can survive in any medium to large sized company. You can also adapt to small growing companies, you know what level of bureaucracy works and what is stifling.

It's not a conspiracy. They just suck.

Try supporting a large O365 environment. Whenever there's a major product release that uses Azure Active Directory, you end up getting redirected to new end points for auth.

Since they also suck at publishing their IP ranges, your users get screwed with random fail until you update your proxy and firewalls.

Office ProPlus is joy too. Try running that on a distributed network where bandwidth is at a premium. Fun UX.

None of those benefits are really accurate though. Automated irrigation is very simple and has been around for a long time. The difference in water usage is negligible, most people don't use a significant amount of water on their gardens to begin with, and using a cover crop or just leaving the weeds alone instead of pulling them out for no reason largely eliminates evaporation losses. I have seen no studies that support the idea that plants grow better. Only deliberately misleading claims from people selling aquaponics systems that compare to soil with no fertilizer or too little water. Hence claims like yours: "they have easier access to nutrients and plenty of water". Those things are both fine in traditional gardens unless you choose to make them not fine.
Oh cool, I'm a big fan of Akhil Amar.
But even with the antisemitism there were always firms who ignored the prejudice and hired on the basis of merit where merit was important. There were never diversity programs.

And there were and still are plenty of firms which didn't/don't hire based on merit. Your argument here is basically "oh well, let's just sweep that under the rug and be hopeful that in the future it'll get better". Diversity programs are about taking the norms of the future and starting to implement them now, because telling people to wait another generation, or another century, for the discrimination against them to fade away naturally is not a great thing to do.
Ask HN: What is the signal-to-noise ratio in your Facebook newsfeed?
For me it is about 1 to 20 - every 20 posts only one is updates from my friends. And the rest are mostly useless clickbait junk that repost again and again.
Hi! I'm the founder / tech lead of Sandstorm. I wrote that "How it Works" page (https://sandstorm.io/how-it-works) and designed the architecture it is describing. Before Sandstorm, I worked at Google on infrastructure for eight years. As you may know, Google has been doing containers and microservices for over a decade. What I describe on the page is largely based on that experience.

> Plenty of precedent there.

I've personally never observed a production (non-research) server architecture which containerizes and sandboxes application servers on a per-document level. That is, say, with Etherpad on Sandstorm, every document you create is in a separate container isolated from the others.

I would love it if you could name some specific examples that work this way, as I'd very might like to see what others have done.
Those changes take away the benefit he outlines for his system. In the US system the President is the most dangerous actor (notwithstanding the Federalist Papers prediction that it would be Congress).

That said, I'm not sure I like the idea of the military as a last resort. At most I think it would be best if they stood aside for a revolution rather than actually instigating a coup.
You realize that just because a tutorial that purports to build a Yelp clone does not mean that it will actually teach you to build the entirety of the Yelp app, right?

Yes, I totally understand the concern. I obviously referred the blog post and there was no intention of mine to plagiarize the content and take sole credit. I am deeply indebted to the open source community and to all the people sharing their knowledge on the internet. Its because of people like them, I am able to learn and grow throughout.

I'll do the needful and add credits to the article wherever possible.
Thanks.

That's still the definition. But if they filmed an episode with an unknown exploit, it didn't get leaked and nobody else finds it between filming and release, it would be 0-day. Very questionable to do though.

I agree that most startups need to get an MVP out the door as soon as possible which leads to clouds. I think hybrid cloud will be the way to go long term.

If you think about it, on one side we have things like AWS and others where devops and "make running your own infra at scale easy" like docker and k8s. On prem in some form isn't going anywhere. What WILL be interesting are the plays like say: convox where you can manage a cloud like you would an on prem openstack/k8s deployment.

Having been brought up in a French system and then going to a US college, I must say I strongly prefer the French system.

I guess Americans would take offense to this view, but I find wearing religious clothing in a public institution such as a school incredibly obnoxious and pushy -- it's akin to your professor suddenly starting to push his/her political views onto you in an unrelated lecture, or something.

It's not that it's bad to wear religious clothing or have political opinions -- it's just that a school should be a place of learning, not propaganda.
Luck Surface Area
I'm working with an architect on a small renovation at the moment. So far, it has been a fairly tedious and frustrating experience.

One of the main annoyances for me has been that, although the domain is completely different, in many ways it's just like designing software in that it can be very involved, with many interactions between small details that quickly multiply.

However, as far as I can tell, while software has stolen some "architecture" terminology, architecture has yet to learn some of the recent advances from software, in terms of prototyping, minimal viable products, and avoiding premature optimization.
Their installation notes involve executing a bash script.

Also, the node package `child_pty` is part of the dependency tree - which doesn't support Windows. This is all totally fine but now I'm genuinely curious about how this builds on Windows.
Yeah, the iPhone was also a dangerous fad that everyone bought into. There was precedent with Newton and palm pilot.
Likewise, thanks :)
I was really into physics in college. After taking a course on chaos theory and one on advanced quantum mechanics, I started getting a very strong feeling that whole quantum mechanics is kinda BS(like its just a mathematical model, not a representation of reality, ala GTR). And that chaotic systems is where the key to understanding the quantum world is.

So I took some time out to step back and see what my life would look like if I pursued physics, given the current state of affairs. Didn't like it at all.

Dropped out, learnt programming, started a company this year, finishing up the product for first 10 customers, and have a very strong feeling that we are onto something big!

Apparently I have more in common with Jefferson than I thought (Re my numerous comments in the past regarding the danger of consumer credit).
I get the grain-per-document thing. Sounds interesting for at least a subset of applications, and disagree with the grandparent that it's common practice.

First question that comes to mind is how the data source is sharded like that. You say in another post that you don't mandate a tech stack. So let's say I want to store my data in MySQL. Are you saying each document literally has its own private database instance?

I have many more questions, but they will depend on your answer to that question. :)
>> Microservices are seemingly designed to match the developer’s mental model of their system. Often, services are literally divided by the team who maintains them.
> Good Lord, I sure hope that's not true. Maybe if the non-technical manager designed the system.

This just seems like a restatement of Conway's Law. Nothing outrageous or egregious about it. It's just how people are.
So companies sell fortune 500 companies pieces of software that, for millions of dollars, scan all deps and recursive deps right on your CI server. They fail the build if a rule trips.

Kind of dumb, but accidently including GPL code in your codebase can be a billion dollar mistake.

If you have no assets who cares. If you have a billion dollar company you should care.
PerceptiveIO Publications
The show isn't just about anarchism and tech. It's about madness -- hell, it basically steals all of Kubrick's most notable filming styles. It will definitely be "weird".
To be picky, there exists no market inherently for proprietary software, only a market for software in which the only way to keep the price above zero is to use artificial scarcity via "IP", DRM, and secret source, etc.

So anyway, the correct software freedom position (what Purism is at least claiming to support) is bigger and independent from libertarianism, so if we were to have the optimal legal framework, it needs 3 things: abolish patents and copyright (not trademark though), mandate source release for published works, prohibit DRM.
Nemesis Machine: Cybernetic Cityscape Visualizes Surveillance Data
The current publications/research listed all seem to come from Microsoft Research, and most of the team members[1] are also ex-MSR/HoloLens researchers. I like how they present their research with video demonstrations - makes it a lot more approachable for someone curious (but less knowledgeable on the area) to quickly grasp the potential applications.

The company, PerceptiveIO, doesn't seem to be affiliated with MSFT though (apparently it's a newly founded SF-based stealth company[2]/R&D Lab[3] in the VR/AR space). Looking forward to see what these guys will come up with going forward; They're certainly off to an interesting start!

Turkish government Gulfstream, and the flight details match up with the reports that he has now landed in Turkey.
Yeah totally. Don't mean to do victim-blaming. But we still live in a bullshit world full of obnoxiousness where you should do things to protect yourself even if that's not fair to expect ideally.
> Huh. It would be nice if we had that here in the US.

That would never function well in the US. It would result in a massive civil war. The general population has hundreds of millions of guns and is very far apart on ideology - that's a lethal combination if unleashed in terms of a violent internal conflict. US culture is also far more aggressive than Turkey's, and the behavior of the government in the US is far more militaristic and violent (and the same is true of the police forces in the US). Such an event would be more likely to permanently rupture the US.

The current article also mentions this subject:

> It's been less than a year since Philips pushed out a firmware update that gave its light fixtures the ability to detect and reject non-Philips lightbulbs -- and thanks to laws like the DMCA, which have metastasized in the IoT era, it's a potential felony to alter your light fixture to override this behavior and force it to work with non-Philips bulbs.
My question is, how does this compare with AppleScript? I've had macs for ages, and I used to automate things with AppleScript (I still do, but I used to, too). I imagine there are some things hammerspoon can do that AppleScript can't do and vice versa. Can the two compliment each other? Call each other?
No, the army gives allegiance to the Constitution. I hope they stand for that against any branch of government.
It was widely noted in the media that France closed its Turkish embassy (on "security fears") two days prior to this. It certainly makes you wonder if the word didn't get out.
So simple that you cannot even provide a link?

This is what I found on the front page of that Google search:

> At the same time, the statute characterizes certain activities as non-actionable “exclusions,” including “any noncommercial use of a mark.”

any any

any

That was from the beginning text of a link on the first page of Google results for the search that you told me to make. Did you read any of the pages? Or is your comment just trolling?

For context, I was responded with:

> That's not how trademarks work.

Care to retract?

Edit: Multiple links on the front page of that search appear to validate my thesis. You have provided no corroborative evidence.

Edit2: Wow, my previous comment was flagged. Brutal. And not even a valid response could be generated.

Edit3: Another choice quote from the front page: "Non-commercial use cannot be prevented, except if that use harms the distinctiveness of the trademark."

Edit4: "The good news is that courts have consistently protected the public's right to use the trademarks of others in order to engage in criticism, commentary, news reporting and other forms of noncommercial expression." First link.

Edit5: "Many companies claim trademark infringement or dilution when pursuing unauthorized uses of their names or logos on the Web - but it's not entirely clear how these laws apply to noncommercial activity on the Net." Contradicts the "definitely" claim that I first responded to.

Edit6: Good thing my post was censored. Might not want to get these claims widely visible.

Edit7: Who is trolling now?

Edit8: Maybe you could give a court citation?
Yeah, sorry but peak oil isn't something that happens on a particular day or hour. There's tons of evidence that we actually already are past peak oil. We're now already getting oil out of tar sands, and if that's even close to economically sensible at all, then it's obvious that the cheap, easy oil is past its peak.

Anyone who thought that peak oil meant immediate real-world decline in availability of gasoline would be deluded. We have too much at stake in our oil-dependent system to let that happen. We'll screw with tax incentives and government systems and all sorts of crazy things and get at the hardest-to-get oil until we get way way way past the peak.

We probably will never hit the point of being on the far tail end of the oil curve because the pollution and climate mayhem will take over before that, so we'll have to stop burning all the oil for environmental reasons long before we run out of oil to burn. But that doesn't mean we haven't peaked our accessible, cheap oil options.

P.S. I have no clue about the voting here. I typically don't see downvote options, and I'm pretty sure you can't tell who downvoted you, so you seem to just be speculating.
Grains of sand in a cloud is a sandstorm. Storms and clouds coming in are both said by people a lot. Synonymous in some situations. Some talk about sandstorms. It's believable that the connection was made without knowing... whatever work you're referencing. Never heard of it.
> Are you saying each document literally has its own private database instance?

Yes. Each "grain" (our catch-all term; could mean "an Etherpad document" or "a Gitlab repo" or "a Wekan board", etc.) gets a slice of filesystem to do whatever it wants with.

Of course, MySQL is totally overkill for this task. We generally encourage people to use sqlite instead. But there are a couple apps that do actually run MySQL in the container, mostly because switching to sqlite would have been too much work. There are also several apps that use Mongo, but it turns out Mongo 3's WiredTiger engine is reasonably efficient for small data sets, so it works out.

The model definitely is friendlier to some kinds of apps than others. Productivity apps with clear data boundaries -- Etherpad (document editor), Wekan (Trello clone), Rocket.Chat (Slack clone), Gitlab, etc. -- work very well, and are our main focus. "Big data processing" apps are not well-suited to this model. We're happy to cede those, as there are tons of people doing great work in that domain.
Tell Google to shove off over what? I don't follow.

Google building a island, claiming sovereignty, and hosting from there, as opposed to from some third country, would be without consequence regardless of whether their claim to sovereignty is deemed legitimate by some international court.

Excellent book. The chapter on cardinality gives a well-written, clear treatment of this important concept (e.g. # of elements in countably vs. uncountably infinite sets).
> Are you saying each document literally has its own private database instance?

Yup. On the other hand, those containers are garbage-collected when nobody is viewing them.
Any plans to support saving/loading grains to IPFS?
Unfortunately my current network appears to block that site. Perhaps you could paste a quote from that page that is relevant to this discussion?

The argument here is that this use is non-commercial (we are also apparently arguing about a non-respondent trademark), so the financial stability of entrepreneurs is irrelevant.
>Unilaterally deleting things without notice and without recourse absolutely does not fit that sort of reasonable definition, although it may well be legal nonetheless for various reasons.

If it is a 1 in a million (or less) chance, then its safer than storing them on your own computer, which I think would fit the definition of safe. You're requiring that Google meet an extreme defintion of safety that is beyond what a reasonable person would expect (since a reasonable person woud likely not backup files, or back them up locally, both of which are less safe than google).

You're conflating control with safety. As in, you're committing the same fallacy that people who are afraid of flying on airplanes do. An airplane is safer than a vehicle. Drive is safer than a computer. People are afriad of airplanes not because it is more dangerous, but because they are sacrificing control.

>there still is no reason to accuse the OP of a strawman argument

I didn't. That was someone else, but I appreciate the downvote nonetheless.
> because long term, they will be better off.

Because long term, they believe they will be better off.

And really, many people cast their vote as a protest vote for the current politics, rather than as a genuine opposition to EU.

Perhaps the idea could be seen differently not as a ban but an enforcement of anonymity. Like its hard for me to judge you based on your username (depends on the username), but if we had profile pictures that wouldn't be the case.

I don't really agree with France on this, but could the ban have positive effects by reducing prejudice by anonymity (look at this person vs. look at this muslim person) vs teaching tolerance.
In the US, the last resort is theoretically the Unorganized Militia. However, as the name implies, they are unorganized and to rely on them is leaning on a broken staff.

They are all aspects of institutional racism in the US; they discriminate against African-Americans, while African immigrant are somewhat shielded from their effects. So, if your argument is that what we term racism should better be called culturism or something, ok I guess so. Still is a real problem.
Is "ut semper" really Latin? It seems a little too cute as a word-for-word fake equivalent of "as always".

I searched perseus for "ut semper" and found two results that might have relevance. The first was this:

> But the expression does not imply that he conceived them as 50 miles in perpendicular height, but that there is a continuous ascent of 50 miles to get to the summit. This explanation of the passage is adopted by Alexandre; Lemaire, ut supra.

Unfortunately, that is evidently English, not Latin.

The second was this:

> Quid quaeris? Est consul φιλόπατρις et, ut semper iudicavi, natura bonus.

(emphasis added)

Which I tentatively translate as "What are you asking? He is a filial consul and, as I have always judged, a good man by nature."

http://www.perseus.tufts.edu/hopper/morph?l=ut&la=la lists ut as having, among many, many other senses, the sense of "adverb of manner", which is the one at play in the above example and would also be the sense relevant to "ut semper". The dictionary entries give a large number of examples, but as far as I can see there are no examples in which the clause following ut does not contain a verb.
