What sort of plants are you ideally suited for?

Almost everything you grow in a garden can grow in aquaponics. The only limitations are extremes: plants that require a really low pH, such as blueberries, large trees (banana trees will wreck your veggie bed), etc.

How important are the fish and aquaculture part?

The fish are very important. They provide the nutrients for the plants (you still would need to add a bit of iron once in a while). Without the fish, you have a hydroponics system, with ongoing nutrient costs.

Maintenance is minimal. When I ran my first proof-of-concept system for a year and a half, I averaged 15 minutes a day, and that was mostly to feed the fish (easily automatable for ~$10).

Do I have to clean the fish tank?

It depends on how clean you want it to be. If you're looking for aquarium-level of cleanliness/clarity, then you'd have to clean it a few times a year. If you're ok with backyard-fish-pond-level cleanliness (a bit of algae growing, etc) then once a year (or less often) is fine.

How do you prevent animals from getting into it and eating your plants or fish?

I had my system in a greenhouse, so that wasn't an issue. If you get an outdoor system installed, you can add a number of off-the-shelf measures to prevent animals from eating your harvest, such as nets.

If this becomes popular, what's preventing competitors from making the same thing, and commoditizing your product?

If we're able to figure out the mushroom media feature, that would be a huge differentiator, but that will be an R&D journey to get there. Another way we can build a sustainable advantage is to develop AI to tell you signs of early-stage pest infestation/disease, and what you can do to avert it (But that requires both smart hardware and software dev).
Quoted from the article:

More SSD drives appear to follow the Deterministic Read After Trim (DRAT) approach defined in the SATA standard a long time ago. This in turn means that a quick format is likely to instantly render deleted evidence inaccessible to standard read operations, even if the drive is acquired with a forensic write-blocking imaging hardware immediately after.
Detonating a makeshift suitcase bomb in a security line, you'd be lucky to kill 10 people.

Maybe. I feel like you're underestimating how many people a bomb in the security line could take out. But, I'm no explosives expert, so you may be correct.

And yes, the worst-case scenario is worse for the airplane, but if you're Joe Terrorist, you don't have to achieve the worst-case scenario to be successful. Terrorists commit all sorts of acts that only kill / maim 10s of people. Apparently terrorists believe those acts further their agenda nonetheless.
I certainly won't dispute that the lows on the right are waaaaaay lower than those on the left.
> plenty of Germans are racist against other populations, especially Muslims

I don't mean to pick on you in particular, but your comment is an example of a pattern I've noticed over the last few years that results in confusion more than clarity -- using the term 'racism' outside of the context of 'race'.

In most cases, I think 'prejudiced' or 'bigoted' is probably a more accurate label when you are talking about irrationally negative attitudes towards religious, political, cultural or national groups.

Not all negative attitudes are necessarily prejudiced or bigoted. Religion and politics exist in the realm of ideas -- one person's 'bigotry' can be another person's rationality and of course reasonable people can agree to disagree without there being any prejudice or bigotry involved.

I think the biggest thing we should take away from this study is that losing weight "The Biggest Loser" style is bad for your long term health, not that everyone who loses weight will gain it all back or that weight loss is impossible. In other words, don't follow a "Biggest Loser" style program to lose weight.
Ask HN: Anyone else annoyed by smartphone animations?
Android user here. I'm talking about the little transitions when you switch between apps, opening menus, etc. I wonder how much faster it would be to navigate around the OS without these animations. I feel like even the simplest task switching takes too long -- about a second, when I mentally expect that it should take only milliseconds (i.e. appear to be instantaneous).

I remember that on Windows OS in the pre-smartphone days, you could turn off animations for opening menus or minimizing windows. I wish there were such an option in Android.
Alloy | San Francisco, CA and Vancouver, BC | Full-time, Onsite | http://alloymetrics.com

The global supply chain powers the journey of raw materials as they become the things we use, wear and eat every day. It generates $20+ trillions every year, and is one of the world’s largest economic drivers.

The supply chain is showing its age: it’s great with goods, but terrible with information. Today, most manufacturers and brands are not able to adequately track how their product reaches the end consumer. Those who are rely on multiple 40 year old data standards, lots of manual Excel work, and hordes of human middleware.

At Alloy, we’re set to change all this. We provide the first comprehensive, low-latency view of demand and inventory across all distribution channels. Our platform connects manufacturers, suppliers, distributors, and retailers, allowing companies to track their products down to the store shelf and better respond to end-consumer demand.

We are early stage, very well funded by leading VCs, and growing. Our team is a small group with diverse backgrounds and experience in analytics, big data, and retail and financial technology. We use Google Compute Engine, Postgres, Redis, Spark, Python, Java, and React.

As an engineer at Alloy, you’ll do any or all of the following:

* Automate the collection, parsing, and storage of huge volumes of data

* Design a flexible but blazing-fast analytics framework that powers instant insights

* Model parts of the supply chain and develop features that bring them together

* Build beautiful, easy-to-use apps that our customer’s love to use

* Dive into server provisioning, deployment, automation, and monitoring

We'd love to hear from you. Send me a note at evan@alloymetrics.com
Regarding safety, we don't even need to call into question my competence with writing safe code :) ; Rust's borrow checker currently precludes a swath of perfectly safe programs. This isn't a knock on Rust; it just means it's not yet intuitive.
I'm pretty sure that the tech kids didn't plan to stay there for more than a few years anyway. They're making big salaries, but the rent is so high that they can't save any money. What they can do is drag that fancy resume back to the Indiana suburb they came from, and buy a nice house with a 20 minute commute to the industrial park that they work in. Or a nice condo in downtown Boise, a five-minute bike ride from their CTO job at some newspaper, or the gas company.

Not necessarily a bad outcome...
That's right. The network project was the means Glushkov envisioned for realizing both economic optimization and a series of other technical upgrades, both wild (like mind uploading) and mundane (like paperless office). Yes, Kantorovich, Glushkov, and the economic cybernetic regulation of market without the market (contra Kosygin-Liberman reforms) figure squarely into the central chapters.

Maciej livetweeted our demo day. I remember sitting there, refreshing, and being both a little relieved but also a little disappointed he didn't skewer us as well.

I also kicked in $5 to his Antarctica experiment. As far as I can tell, he's made a lot of good choices in his life, and would use the investment wisely.
You can down servers or backends over the stats socket, but you can't add them (adding servers requires a reload).

The DNS resolution work that is going into 1.6 releases may lead to a workable approach where you over allocate servers in a backend and then update them to have the right host/port. Last I checked, however, you still couldn't set the port dynamically.
It is beneficial in that it discourages proprietary backends to LLVM which are not contributed back to LLVM. It is the same benefit GCC enjoys by using GPL.
Curious what an ultracool dwarf star would like like from an orbiting planet considering it emits radiation in the infrared band? What would the flora/fauna look like? How do they evolve in an infrared environment?

An email has at least three fields that can both influence the address to which a reply goes and isn't necessarily visible to the recipient's MUA. Even if the recipient where to look into the headers, there are plenty of games to play with deceptively constructed international domain names. There is also the social engineering aspect I mentioned.
Democracies end when they are too democratic
> I really, really, really doubt that.

I agree. And it goes beyond just being cooped up.

Having a planet's atmosphere to burn up flying space debris or at least being inside of a cave in an asteroid (as long as it is really a cave) can provide a lot of protection. A high-speed space rock could easily tear through the one foot of protective wall in your space station, and all of the pretty plants and oxygen in your biosphere will be dead from having been almost instantly frozen, even if you patch it up.

If we want colonization, we not only need orbiting stations/stations at Lagrangian points, we must be colonizing big rocks. Once you perfect your shields, it's another story, but we are nowhere near the energy requirements or technology of a ship or viable station that is safe for humanity to live in long-term. Even if I live to be 1000 years old, I'd never want to take my chances in a station or ship that isn't at least in orbit, protected by a large planet on one side, for any great length of time. And our orbit is filled with space junk- not very safe.

Now, if it were a Firefly-class ship, that'd be different. I'd live in that in a heartbeat. Or the original Enterprise or the Tantive IV.
The problem with this indiscriminate propping up of women is that it doesn't work, or else we'd be doing this for everyone. But we live in a mostly meritocratic society because that system is better than indiscriminate merit.

So while they indiscriminately endorse any women, the women who merit endorsement more will inevitably be disenfranchised more.

Right. And Wright and everyone involved must know that. So can anyone explain their motives? I truly can't figure that part out.

Edit: alain makes a good point. It's not the 'motives' I want to know. I want the whole story.
The earth has a wide variety of resources important to comfortable human life. The moon has rocks and sand and sunshine. Moon mining is but one of the prerequisites to living cheaply in space.

Exactly! If this is indeed a major factor, could we see the SF housing market nose-dive if/when the Chinese market does at the same time? Or if/when better investment vehicles become available to them domestically?
Huh? Active Denver resident for the past 6 years and i have never waited more than 30 minutes at a restaurant here. I work on the mentioned intersection and dine daily for lunch, with no wait regardless of my choice.

Well, perhaps you share his cultural context, then; I clearly do not, since he begins with statements which simply are not compatible with my experience of life and builds on them in ways which do not make any sense from my perspective on the world. I gave up halfway in, because he had gone so far off into his own self-referential argument that I could no longer even parse what he was trying to say.
But as you rightly point out that costs money. I've been thinking about paying for some of the sites I use frequently but if you add up $5 a bunch of times you get to pretty big numbers per month. Also $5 for one website? That's 1/2 a Netflix subscription and for that I get an insane amount of content! There has to be a way to pool these fees in a sustainable manner so that I can buy many quality news sites at once.
If you can't charge her with a crime then why are you holding her?
Great lead. Glushkov's network ideas are definitely overlooked, but the parallel with the CDMA in weak. Perhaps a stronger parallel is with, say, Lashkaryov's p-n junction, which became an important innovation (semiconductor) but thanks to others elsewhere. Loren Graham's Lonely Ideas is a great book for more on the larger history of brilliant ideas and halting innovations.

Ohio as a whole is boring. Hardly any outdoor activities and the only scenery is corn. I guess if you like amusement parks, but besides that, it has to be one of the most generic/bland populated states.
But is it a development in the crypto field, requiring someone super talented in crypto?

From my understanding (though no deeper than what's in the Bitcoin whitepaper), the central new idea (and it is indeed a significant contribution to CS in general) is laying out of how to build a distributed timestamp server, and then distributed ledger from only untrusted peers by using existing technologies circa 2009 such as p2p, hashing data blocks, priv/public key for verify/sign, etc.
Megalomaniacs will keep lying and dig a deeper and deeper hole for themselves. You start with a small lie, and just can't stop, you have to keep going.

What's surprising though is the lack of judgment from BBC and other major news media. That same person made the same bogus claim 6 months ago. How does that not trigger major red flags? The only story worth writing about here is how he pulled off such a trick.

This is like God's existence. There is a simple way for God to tell us He exists, and which religion is right. But He never does. Instead, we must rely on testimony from various people, contradicting each other, and none of it is reproducible. Sure, you can believe... </controversial statement>

Rather than IAM, you can as well just associate the service account with the VM, in which case you don't have to copy around the json file with the private key. Any gcloud calls from the VM will not need explicit authorization.
Git Mind Map
I think the difference is that you've stated explicitly that you'd rather be King than Rich, while Maciej's response when asked that was "I feel like after seven years, I have a pretty good sense of what bookmarking/archiving needs people have, but am at the limits of what I can personally build. If the votes swing my way, I'd be happy to have a good-faith conversation with you", i.e. as long as YC didn't try to turn Pinboard into something it isn't, he'd be willing to listen to ideas that may help it reach more people. The difference is pretty subtle, but it basically amounts to "Is YC wasting its time with its advice?" It also helps that it's Kevin Hale opening the conversation, and Wufoo was not unlike Pinboard (or Tarsnap, for that matter).

Nothing wrong with being King, BTW, but YC's made it clear that it's not willing to play court jester.
> Under many readings of US law (specifically, ECPA), US companies are in fact prohibited from complying with requests from foreign law enforcement for content

i know nothing about law, but where are you getting this from? does not seems to be the case with any company in china (yahoo gave in, google decided to leave) for example.
> has no presence in Brazil.

If they have no presence in Brazil, how did they get shut down in Brazil? I don't mean to be glib, but I don't see how the two concepts jive with each other.

On a purely practical level, if they were interesting in maintaining their service in Brazil, why didn't they establish a presence in Brazil when all these previous orders and shutdowns were going on? This is like ignoring notices in the mail and then wondering why you're getting collections calls.

Completely agreed. For anyone interested in the heyday of Soviet economics, please start with Spufford's fascinating and entertaining historical fiction! :)
>* Brazilian law regarding regarding privacy of users of internet services is very recent and clear: if a judge order the company to share a specific user data, the company must comply. You can disagree with the law, but the law is there.*

So? Like Jim Crow laws, merely "being there" is too little justification for a law.

BS!

they have bank accounts and deals with many tel co to operate as they do in each country they are.

you do not get pre-installed on the three biggest mobile operators phones (99.9% of market) and get deals where data to your service do not count as part of the limited data-plan on two of them, by just "being an IP address on the web".
>Again, it's not evidence.

Repeating that will not make it so. The code is available, it is fully documented and reproducible. That is not an anecdote.

>The compile times are only shown in the Nim board comment, not the Github page, which doesn't benchmark compilation times. Again, where did the numbers come from?

So? Evidence does not become anecdote simply because you dislike the source. It doesn't need to be on github. It is where it is because the person who did it put it there.

>Secondly, again, it was for a ~70-line program. Do you seriously think that benchmarking the compilation of a 70-line program is statistically valuable?

If you want to make the argument that it is weak evidence then do so. But your insistence on dishonestly claiming evidence is anecdote is not constructive.

>You completely missed the point of my JVM comment

No I did not, I pointed out that it is nonsense.

>Actually, I'm going to assume you're trolling. I'll stop here.

The thing about journalism is you don't need all of them to be good, or even the median or mean journalist to be good -- just the top few to be amazing.

I agree -- we need people who are actual experts in the field, but also good at communicating, when communicating about topics where expertise is valuable. There are some amazing war correspondent journalists who go into harm's way and have both shared experience and a reasonable background.
> what mechanism would they use to communicate?

That's up to the program embedding them -- the idea is that you're the one implementing the communication and synchronization in the embedding program, rather than in Wren itself.

Hal Finney received the first Bitcoin transaction. Here’s how he describes it
Where I'm from, that "green turn arrow" is called a "protected left". While I can't say I've ever heard unprotected left, the term makes sense as a logical extension of the lexicon. (And as a Bay Area resident… I chuckled at the remark about being able to make unprotected lefts.)

I will occasionally abuse the term with the term "protected right", to mean waiting at a red light where the cross traffic moving leftwards has a protected left. (because the cross traffic's left is protected, the only conflict with a right-turn-on-red is someone in the cross traffic U-turning.)
