Plants already love grey water as it often contains phosphates and nitrogen from lawn runoff.

Using uncontrolled water like that, especially if you're counting on it being contaminated with feed already, is a recipe for disaster. Some crops like tomatoes, cucumbers, zucchini/squash as examples really do not like nitrogen as they get into the fruiting stage. Too much and they'll remain in their vegetative growing state and just not bothering with the flowering and fruiting. You sometimes see that in ornamental plants too. Trumpet Vine is one that comes to mind. Too much nitrogen and it won't flower. Beyond that you would still want to sanitize the water. Grey water, I assume, would likely be contaminated just as much as surface water (ie: a pond) and therefore require a bit more work which is something I know about. I work in a greenhouse and I'm the guy that gets to muddle with ozone, chlorine, hydrogen peroxcide, or whatever else we're using to clean the water up. Failure to keep the water clean leads to, at least, clogging of irrigation emitters and at worst fungal diseases. Even if you're working with water so clean you could drink it you STILL generally put something in the lines to keep thing sanitary.

If you're lucky, you find a space whose roof is missing and you cover it over with that corrugated fiberglass stuff they normally roof greenhouses with.

You don't normally line a greenhouse roof with the corrugated plastic. It doesn't let enough light through compared to other methods and it also doesn't have the insulation factor.

Most roofs are plastic sheeting, nice and clear, with UV blocking on the outside and IR reflection on the inner layer. You install it with two sheets, clip it all down, and then pump and air blower into the cavity between the two for your insulation.

<blockquote>- wasn't there a sniper at the University of Texas Austin campus back in the 60s? Everyone raced home and got their rifles, and the end result is there were more deaths from friendly fire than deaths caused by the sniper. In fact, a police officer who took down the sniper was nearly taken down himself from one such equipped student.</blockquote>

Nope. Charles Whitman shot and killed 14 people from the tower that day. There were 18 casualties total including Whitman himself, an unborn baby inside his first shooting victim, and Whitman's wife and mother who he murdered before the shooting spree. I have never heard any reports of civilian fire resulting in casualties.

When you say that a "police officer who took down the sniper was nearly taken down himself one such equipped student" -- you're probably getting the events wrong. When they entered the tower three police officers and one regular civilian (Allen Crum, age 40) went in. Crum negligently fired his rifle when they got to the top observation deck. The police provided the weapon to Crum.

If you mean the manual safety you flip on and off, yes, there were and are objections to them. You'll be hard pressed to find a police force in the US issuing a gun with a manual safety. Instead they use guns which have a double-action pull (at least on the first shot) or something kinda like that in the case of Glock which is not quite double-action but somewhat close.

Time and research has found that when under stress people forget to flick the safety off.

rsync sorta breaks down when you're dealing with large amounts of data because it has to scan all of it remotely and locally. True, it doesn't transfer much, but it can take an awful long time to figure out what's actually needs transferring.

ZFS (the filesystem... probably don't need to be pointed out on ./) on the other hand knows what blocks have changed and would probably work better. I've only tinkered with it in VM environments but I would like to give it a spin as an offsite backup sync solution.

1) You can distribute 80% complete receives without any paperwork, not 90%.

2) Who says they're a problem? Despite random hand wringing over the subject I don't recall ever seeing an 80% receiver tried to a crime.

3) Just a hunch but if you don't like the 80% rule you won't be happy with a 70% rule or 50% or 25%, 0% or even -10%. What's a -10% receiver? I'd call starting with a rusty shovel and banging that into an AK a -10%... and it has been done:!

Comment Re:So do marijuana cultivators. (Score 3, Interesting) 173

I come from a greenhouse family, and I remember using CO2 generators in the 90's briefly. I asked about this a few months ago and they quit because it prompted too much growth in some crops so they nixed the idea.

The reason I asked the question is I was coming back from a small class put on by MSU Extensions (Eric Runkle lead it) about LED lighting. He briefly touched on CO2 generation and it was basically a toss out of... "Yeah, we used to suggest that but ambient is now over 400ppm, so if you think you're low just crack a vent. I've seen some greenhouses down to 200ppm. Impressive they had it that sealed up, but just vent and you'll come back into the 400's." -- paraphrasing a lot there. I didn't take notes.

Comment Re:just do it (Score 1) 225

That was always a red herring and never an issue. Especially when you consider that debit card transactions (with PIN) are very common in the U.S. Arguably more common than credit cards, depending on the retailer.

No, it's not a red herring. People do not remember their PINs. I'm in a weird spot where I went from software development into the garden center business and I wrote our POS software that we've been running for about 4 years now. I also become a cashier on occasion. My POS software looks up the BIN range of the card based on a list given to us by our CC processor and will ask the user for a PIN if they have swiped a debit card. I'd say it's about 50:50 if they actually put in their PIN. I don't have good data on that one. I should but I don't flag the response from the CC provider as debit or credit. But, experience from working a lane is that an awful lot of people will revert to credit instead of PIN debit... and some explain it as they don't know their PIN.

Now that we're on an EMV system some cards register as PIN auth and the pad asks or it automatically. I've already seen customers that don't know their PIN so the sale can't proceed. Not good. One guy came through and explained to us, and this is embarrassing to myself and the CC processing industry trying to secure stuff, that generally if you just hit "enter" or the "green button" when an EMV card asks for a PIN the system reverts to signature. He was right.

Why do PIN pads revert to signature if a PIN isn't provided? People are too stupid to remember their PIN. It's not a red herring.

Conventional breeding isn't guaranteed to be safe either. In the 60's we bred a poisonous potato on accident:

I'm sure there's more example of stuff like that happening but it's the only one I know off the top of my head. We've been doing conventional breeding for about 10,000 years and we only discovered DNA in the last century. You don't think we made another dud in the previous 9,900 years of mucking with plant DNA before we even knew what it was?

You think it's more dangerous to splice in an isolated sequence into a known plant and then test the snot out of it before releasing it compared to caveman Og bumping plant sex organs into one another and hoping the offspring is better?

- In 2011, newly elected Governor Rick Snyder passed Public Act 4 which allowed him to appoint an Emergency Manager over financially distressed cities with the power to liquidate assets, suspend and renegotiate contracts, and even disincorporate cities.

That's a bit of a half-truth. Michigan's Emergency Financial Manager laws were put in place back in 1990 under Democratic governor Blanchard. It wasn't used too much, but Democratic governor Granholm (2003-2011) appointed 7 of them. With the slight expansion of powers in the 2011-2012 changes one concession was that the local government could boot an EFM after 18 months. Granted, if the "triggers" to require an EFM were still there they'd get a new one, but that's probably why Flint has bounced through so many since 2011.

WikiPedia has a handy chart of when/where they were used in Michigan.

The blind partisan vitriol on the issue of EFMs is rather staggering to me. I've seen Snyder called a racist for appointing an EFM (like in Benton Harbor) when all he did was reappoint the EFM previous governor Granholm had already put in place.

And it's not like the new water treatment system was a new idea. Flint spent $50 million upgrading their unused water treatment system between 1998 and 2006, well before anything related to EFMs came into play, though they were under one from 2002-2004. I don't think it's all that illogical to ask/force a city government that just spent $50 million on a water treatment plant to actually use it instead of buying it from Detroit and letting the plant sit idle while they go broke.

. Like i said i take exception to the idea that all this traffic needs to be encrypted by default, not the idea of encryption. Your argument is security through obscurity and nothing more.

No, using decent encryption is not security through obscurity.

Security through obscurity is when you assume nobody will crack your system because they don't know some magic number or method of yours, or some fatal flaw in your software.

It doesn't mean using encryption to make the pile of encrypted data even larger for those that want to decrypt it. That's perfectly sound thinking.

Comment Re:IPsec or simple ssh like tunneling (Score 2) 136

don't think the OP gets a choice in the matter. Most IP cameras and IP camera system transmit the video feed over a UDP-based protocol; it's generally RTP/RTSP; and support for SRTP/SRTCP is sparse and far between (Unless you spent mucho more $$$ to purchase high-end equipment that specifically supports it!). The only way you're going to be wrapping RTCP in HTTPS is with a SSL VPN that supports encapsulating arbitrary TCP protocols and the UDP-based RTP streams as well.

Bluecherry ( can wrap up RTSP into an HTTPS transport nicely... and I don't consider it all that expensive at $500 for a 32 camera license which is good as long as that version is supported. Hell, it can suck up MJPEG and coax cameras and rebroadcast them in HTTPS encapsulated RTSP too. It's not even a selling point of the product, just a smart decision that they made when designing it. Basically the Bluecherry server pulls up all the RTSP H.264 or MPEG, MJPEG, and coax camera feeds, transcodes them on the fly into H.264 for storage, and then rebroadcasts them over RTSP for their cross-platform client to display live. You can also suck that RTSP feed into VLC or whatever else you want.

And, perhaps nicest of all given the topic, Apache handles the HTTPS traffic, not their server, so anything possible in Apache is already at your fingertips.

The product has warts, but they designed the thing so logically that I can't help but love it, and their team bangs out stuff awful fast. The product is probably 300% better than it was in 2012 when I started using it and I didn't dislike it back then.

Comment Re:It's the farmers ... (Score 3, Insightful) 93

Neonics have been in popular use since the 90's and increasing every year. If the use of them was hurting yield (it isn't) farmers would have noticed by now. They're using them because it increases yield in a cost effective manner and it's not a simple story.

Neonics are useful because they're deliverable in powder form, you can coat a seed with it, and it'll protect the seed from insects while germinating. After that the plant will take up the chemical to provide some systemic activity for a period of time. This helps the young plants get established. After about 30 days they're gone and not doing anything.

They started being used in the 90's for field farming because you could seed at a lower rate, but seed is, generally, very cheap so it wasn't too common. Pumpkins? Sure. Corn? No way -- too cheap of seed. When GMO corn, soy, cotton, etc came along THEN you saw a big uptick in neonics as it was now beneficial to protect those seeds as the GMO crops were fairly expensive seed.

Apiaries (bee keepers) might be taking a bit of hit but that's just part of dropping your bees off at a farm where a simple mistake can kill most of them. One entymologist I've heard speak on this pointed out a farm that killed a bunch of rented bees with vegetable oil... and yes vegetable oil is an insecticide. Another killed a bunch with RoundUp, an herbicide, but too much will kill a bee. Pretty much anything will kill a bee. The fact that neonics aren't terribly fatal to them is amazing, and public resistance to them confounds me and generally every other guy that's donned a chem suit and went to town on bugs. The alternatives are generally horrible to bees. Push back on neonics is going to result in more pyrethroids, carbamates and organophosphates. Every single one is toxic to bees, horribly so, and carbamates and organophosphates are bad news for humans.
