Except that the bulk of water used by cattle production is that >same< irrigation. I can't find numbers breaking down the irrigation usage, but I would be surprised if it doesn't comprise the bulk of agricultural irrigation.

How about using a tested login library instead and consider using OAuth as well (e.g. Google account to login)?

Rolling your own login system, dealing with hash functions and checking passwords yourself is far too low level and dangerous for most apps (as this thread demonstrates).
I apologize if I offended anyone and/or if I said anything improper; it was not my intention. I wrote this quickly during the March "Who's hiring" thread and copy/pasted it today. The role that was linked last month is a very early entry, out of college, role. 99% of our applicants for these roles are under 30 so I can only guess it was a subconscious thing on my part to put "young" in the description.

Thanks for holding me accountable!
A state with questionably the highest concentration of some of the most intelligent people in the U.S and some of the dumbest politicians in the U.S. Question :
What were all of the Californian's doing when the state was running out of water for years? Why do you elect bozos? Too busy making apps to be concerned with where you're going to get water from?

Ever wonder where all that tax revenue goes? Apparently not to important issues.. Planning ahead.. wtf is that?

Yes, Agriculture burns up 80% of the water supply... California is a desert yet attempts to be the source of the nation's agriculture .. $$$

Every step of the way, money is a motivator over survival.
As a result, even with the current order, it wont go far in way of solving the water issues. In all honesty, it seems no one in that state is going to wake up until all of its gone. Maybe then people will wake up. 194 comments and counting about doing everything under the sun and nothing of value is done about it. Where's Zuckerberg? Where's Google? What are the problem solvers of the world in that state doing? Exactly....

Good luck California. You elected these bozos and sit by worrying about everything but what's important. The very nature that attracts people to the state and the lifeblood of habitability is under threat and no one has bat an eye for years... You can't get Zuckerberg to shut up about flooding an already flooded workforce with outsiders. Yet, the whole state's water supply is under threat and no one has said a word. Not one person from the 'leadership'...
Gotta love the times we live in.
The water restriction measures are mostly bikeshedding (yes, removing public lawns is probably a good thing) on low consumption behaviors on those consitutents viewed to be most accepting and least threatening to the political establishment. It's akin to allowing Diesel trucks older than 1998 in CA to continue spewing particulates into the air because regulation would be "too expensive," and instead highly regulate passenger vehicles. Both are needed, as holistic solutions to diffuse problems tend to be the best, but asking one group to shoulder a collective burden is horse baloney. Yet, the action of the governor is a signal of an ongoing issue but it's token as it doesn't start to address the quagmire of where legacy water rights meets gamification and usage with sensible limitations. If CA doesn't work on the larger structural water allocation issues, water will become more scarce and expensive because a few large, influential farmers will continue to make themselves rich at everyone else's expense. (Carbon emissions need to go down too.)

Maybe CA needs well-informed grassroots picketing against farmer water rights gluttony in Sacramento?

Awesome - more stuff like this please. Flow-based programming is a really great thing and this is a good start. Props for making it available as a local service; this seems reasonably robust and usable, especially for a first iteration. More examples would be good, as would nestable macros. Native Instrument's digital audio tool Reaktor is a great example of what can be achieved in this area, as are the tools from DSP Robotics, which are also a little more code-oriented.

Win 64 Binaries work fine, but they unpack to a file called 'st' which has to be renamed to 'st.exe'. Tsk tsk. From the docs:

if you're a Windows user we do provide binaries but don't know much about how to interact with a Windows machine - you will need to translate these instructions to Windows yourself.

haha. It's not that scary folks, try it!

ugh. CMake is atrocious. It covers maybe .1% of the cases that autotools handles while having some of the worst documentation known to man. Not to mention yet another language to learn. It's not more "modern" than autotools and it's in no way shape or form "newer" than autotools, seeing that automake/autoconf have been in active development since inception.
For anybody who wants to take a look at the types of exercises they have: all the exercises are on github [1]

I didn't say it was bleak. The difference is that on Linux/OSX you don't need to install extra tools like mysysgit/cgywin or a different terminal emulator (ie, Cmndr or other 'Terminal' replacement on OSX), because the toolset is already there (bash, awk, sed, etc).

Also, the thing here is that it's not optimal, and there's also non-trivial licensing costs when building large continuous integration/deployment systems. Additionally, I don't believe you would be very supportive of the experience on Windows if you were more familiar with what is possible on Linux, OSX or any other Unix, and if you had strong understanding/knowledge/command of the toolsets available on those ecosystems.

There is nothing fundamentally wrong with using Windows as a regular desktop environment (I'm forced to almost every day). It's actually a fairly good experience (from a desktop perspective), but it doesn't give developers and system admins true, powerful out of the box toolsets. For instance, installing PostgreSQL/MySQL/Apache/Nginx/or whatever on Windows is extremely painful, cumbersome, and not standardized across systems. Conversely, compare this: (yum|apt-get|port) install (postgresql|mysql|apache|nginx).

To do proper automation on large sets of Windows systems, you need Windows Server, Active Directory, and Domains properly setup configured, and licensed, especially if you have any kind of security policy and need to push / control updates from a central server and keep strict control of / standardized versions across systems (for instance, in a strict, actually PCI compliant environment). Why bother with any of that when all of that mess / problem is taken care of by your distribution (OSX/Linux/etc), as one would expect it to be. There's no dependency graphs with large sets of Unix-likes, unlike in the Windows ecosystem -- and that really is the main issue here.

The future AWS is driving towards is where they are the power generation company that nobody has onsite either (except for very rare circumstances).

You might keep some temporary capacity / backups locally, but you'll depend on the utility to be there for the vast majority of things.

The market will see if that's the future or not...
Understood - but, at least you have been forewarned by the man pages, that any changes you've made to /etc/rc are going to have to be carried forward, because after an upgrade, /etc/rc will be wiped and set to the operating system version.

I'm a basic novice when it comes to OpenBSD (But a huge fan), and that, in addition to discovering that you keep all the old versions of every library ever installed when upgrading, where two things that I had been taught - so I presume that the knowledge was universal.

> sorry about that...in all honesty, it was the most epic email that I read about the challenge :) (and I told the team!)

Aw shucks. Well you guys are OK after all.

You know, if I had a dollar for every time I didn't get back to someone's email when I should have, I'd be rich by now.

Tell you what. Do you bring in lunch for the team from time to time? We are neighbors: invite me over and all will be forgiven! I got Drew's email and will be sending over an RFL shortly. :-)

Actually, that would be a brilliant strategy for any company that puts out coding challenges like this: Once in a while, when someone local sends an interesting solution but doesn't seem like a fit for the job you're looking for, invite them over for lunch anyway just to say thanks! Who doesn't like a chance to meet smart hackers and enjoy good food?

What if an ISDS tribunal continually levied fines against a nation-state member for damages caused by a breach of international law?

Would that nation-state eventually feel pressured to change its laws to avoid crippling fines?
I believe this derives from the many immigrant groups that have come to the US over the centuries, each with a very different cultural view of what constitutes "correct" behavior. The only way to avoid constant fighting in that situation is for most people to say, "OK, as long as you are not directly harming me, you do what you want and I will ignore it."

Europe, by contrast, is far more ethnically homogenous than the US within individual countries. Most people in most places share a very similar cultural background and very similar views of what is "correct," so the pressure to conform is greater.

The Windows x64 .tar.gz extracts to a file with no extension. It's actually a .exe that you then run to stat a webserver on localhost. It'll assign a port that you can connect to.

edit: I'm trying to do the 'hello world' tutorial but I don't think my fromhttpstream block is updating when I hit Update. It blanks out the Endpoint area when I hit update, but then seems to do nothing when it's connected to a tolog block.
So, I get what you're saying, but the particular locations are completely irrelevant to the math/CS.
Looking forward to porting my FOSS newsreader over. Nice work, this.
In general, "machine learning" means that an algorithm did it, and that the algorithm engages in some analysis of the problem space or the solution space. Usually that analysis involves an iterative or repetitive element: making several tries and modeling what makes a try good or bad, making a try and then changing the solution tiny bits to find a try that's slightly better, etc. And "good" or "bad" is determined according to a human-provided rubric (eg: +1000 points for every sight seen, -1 point for every mile driven, -10 points for every day taken, etc.)

Unless the problem is very constrained, there usually is no guarantee of optimality; here there is probably no guarantee of optimality. It might be "locally" optimal, in that there might be no better trip that differs from this one by only a tiny bit.

And, no, "machine learning" here doesn't mean the enterprise and establishment of "Machine Learning", just some algorithm that the author used.
Actually it isn't that hard. The land value is simply the property value minus the value of the depreciated physical capital (buildings etc.) on it (LV = PV - K). This calculation is already done in the market in order to determine the size of a home owners insurance policy. Property tax values aren't ideally precise, but are already common enough that replacing them with and land value tax wouldn't greatly impact tax code precision.

To address your more general critique, it might be better said that you are paying a location tax as opposed to a land tax. Specific locations have particular value and until we develop hand of god technology, putting multiple units of land in a given location will be impossible. So land vs. location is really just a semantic difference.
This UX & UI opportunity excites me.

Richard you have four separate ads posted all over this page, consider grouping them :)
but maybe a JS lib could step in to come up with a reliable way of doing it

That just moves the problem of its definition being vague from the browser developers to the JS lib developers... and there are so many more of the latter than the former that I could see it resulting in various libraries adopting slightly different definitions. It does make it easier to adopt one definition across browsers though.
A 403 only works in the case that you have an all-or-nothing authentication scheme.

A 403 for a resource that exists but is unauthorised leaks the information that the resource exists.

Many Github customers don't want people to be able to guess at their private repos, and the 404 is the only code that is legitimately able to express the union of "not here" and "not here because you're not allowed to know it's here".
That's the "Big Switch" theory. It's one possible future although my sense is that there's considerable skepticism about it from both the perspective of where the economical scale points sit and with respect to governance/control.
+1 you are exactly right on this. It takes about 10 times the water and 10 times the energy to eat mostly meat.

I would argue that a mostly vegetarian diet is healthier also. One problem is that it takes some degree of skill to cook a delicious vegetarian meal, but is fairly easy to make a tasty meal out of meat.
What you seem to be missing is that the post is specifically about conversion between floating points encoded in decimal and floating point encoded in binary. BCD are decimal digits encoded as binary, they're not binary-based floating point.

It is made clear from the very first sentence of the article that it is about representations that will round-trip between number bases, not whether or not it is possible to encode decimal floating point numbers with two digit accuracy in 7 bits.
