It depends on how much you want to idealize things. If you add the assumption that all flights/trains/etc. are available every day, and the price never changes, then yes. In reality, trying to traverse a weighted graph optimally with a bunch of constraints (arrival times, how long to stay in each place, preference for difference modes of transit, transit times) is a whole field of research in math/CS. Operations research [1] is the study of optimizing processes with many interrelated factors.

> It's true that artificial sweeteners have no immediate effect on appetite

Yes, but the quote you give doesn't mention immediate effects in particular. And to the contrary, they mention things like obesity and diabetes which are not immediate effects.

To me, it sounds like they are not saying what you say they are.

Those OKCupid statics are really useful, they help you understand what's commonly expected, e.g. if you date outside the commonly accepted age range, you might face additional challenge than others. That is useful information to have, so you can be prepared for such challenges.

But for gods sake, use that information to your advantage, not handy-cap your own mind, same as how you should use any other kinds of knowledge.
True. As I understood them though, the criticism was primarily about his message that fructose would be the key or only reason of metabolic syndrome, or his depiction of sugar as pure evil rather than as something which you can consume in small amounts, more than about the effects of fructose itself. (When not, connections between the critic and the sugar or food industry were quick to Google, thereby reducing the credibility to zero.) This may have changed since I spent time digging into it, though, so please expand if it has.
Yeah. I'm thinking of Joel Spolsky's 199/200 who are just the same bozos cycling through interviews until someone hires them by accident ...

"devops" is fighting words in our team. Damn, if I could get our devs who'd like "devops" on their CV to give a hoot about the "-ops" half of that buzzword ... when a dev shows awareness of ops issues with their shiny new thing, I make a point of mentioning their name positively to the dev manager. "X knows their stuff. Give them more good stuff."
Yeah, but B5Geek's is a pretty entry-level thing. I've encountered whiteboard tests where you have to recreate an algorithm that someone spent their PhD thesis creating. It seems like a good way to find "geniuses", but it just isn't practical.

In a lot of ways, it's a matter of identity crisis for software developers. We're all, industry included, not quite sure whether we're mechanics, carpenters, architects or scientists.
While not as significant as that of women, we men seem have a biological clock as well. With all due respect, personally, I do not think that pinning things entirely women is a healthy attitude.

"A 2014 study had experts suggesting that the debate based on mixed evidence whether a father’s age is linked to his child’s vulnerability to individual disorders like autism and schizophrenia had been settled.[6][7] The result being that "Men have a biological clock of sorts because of random mutations in sperm over time". Dr. Patrick F. Sullivan, a professor of genetics at the University of North Carolina, who was not involved in the study said "This is the best paper I’ve seen on this topic, and it suggests several lines of inquiry into mental illness"."

It looks like the level objective indicator is broken. Each of the three flasks that indicate what color you're supposed to drop in are shaped like an erlenmeyer flask, when I think there should be one erlenmeyer, one cylindrical and one spherical flask so you can differentiate what color to mix into which type of flask.
The abstract is not paywalled. I understand that my comment may seem rude, but tokenadult's basically useless comment was in the first spot for a good half hour, above a better comment thread, until I posted and several readers downvoted it.

In my opinion, tokenadult abuses his high karma average somewhat too often. Here's how it works: if you have a high comment average, your comment sorts higher than others with a similar number of up-votes. So if you post early enough, before anybody has written anything very interesting, your comment will stick to the top. If it's even vaguely useful to the casual reader—you post an article abstract copied and pasted from the the submission, say—you can then hold down the top comment spot, garner a lot of up-votes, pad your average, and stifle a more meaningful discussion. Maybe you come along later and edit in some actual information.

I find it obnoxious, and I wish tokenadult would stop doing it. (And I really only commented because I accidentally upvoted him, prolonging his comment's contentless primacy.)
True. Testing for sysadmins is easier: you're after a way of thinking. So a competence test ("can you do what you claimed?") with a freeform "keep notes on your thinking along the way" is quite informative. You still need to interview, of course.

I confess I don't know how I'd apply this to developers. They pass fizzbuzz, OK - what do you do next?

First, you don't know if he downloaded the file from this machine. It could even be networkless.

Second, instead of a VM, it could be a livecd with no permanent storage attached. That's what I'd do if I had to debug potentially malicious binaries.

It's fine to ask, but it's wrong to assume.
Because I prefer it mostly, I wanted the option to use it as a library as well so I left that open.
How the FiveThirtyEight Senate Forecast Model Works
Asyncio wasn't added until 3.4, so it was hardly the initial thrust of what Python 3k was trying to accomplish. Guido even admits he didn't even understand how Twisted's Deferred's worked until a year ago: https://groups.google.com/forum/#!topic/python-tulip/ut4vTG-...

... which I think is great that he really took the time and Pep 3156 is the better for it. I still feel like this should have been what Py3K was about though, and not tightening up semantics in the language. Who cares about the semantics? Python has warts but we love it anyway.
:) When devs are in the loop it always comes to "working in localhost" debate. I like to say developers are working or living in their isolated bubble. And whenever their code comes out of that bubble and reach the real world ops are on fire.

Always the ops guys are in fault.

I think every developer should be given sysadmin 101 and 102 lessons.
Even in the current pre-alpha/alpha stage of Guile-Emacs, I can launch a thread from Scheme, do work, return to the main thread, then call an Elisp function on my result. (Scheme and Elisp data types are unified.) No bugs or unpleasant details there.

Calling Elisp functions and accessing Emacs data types (buffers, windows) from multiple threads is another issue; if you don't want to bother with it then don't; you still get all the other benefits of being on Guile. (Calling to any Guile module agnostically as if it were an Elisp library (including, say, Guile's OpenGL module), having an FFI, getting JIT or AOT native compilation in the future, etc.)
Teaching Art to Kids in New York
For the most part I don't complain if asked for an hour (or less) worth of work.

I did something similar in Python, using Redis for the "operating system" and Linux processes. The system managed wide sets of parallel I/O operations with second-level latency. Worked great, albeit orders of magnitude slower than something like this. If you keep the supervisor on the same machine, you can do async exceptions via kill.
I only skimmed through the documentation, so I must have missed something, but I fail to see how it can be better than either redo[0] or tup[1] in either speed or dependency tracking.

Guile-Emacs is not a rework, it's a rebase. It already runs all Elisp, sans bugs and (currently severe) performance regressions. It will be a nearly-drop-in replacement, a new version of GNU Emacs, even less different from it than XEmacs. In general, it will only add to Emacs, and change the underlying implementation of Elisp.

It's also illustrative to ask what reforms are possible in a society like the U.S. has: http://www.explainingprogress.com/wp-content/uploads/2013/03.... The U.S. homicide rate has been 5-7x higher than in England for more than a century. You can't blame it on the drug war or on Prohibition: it was 7x higher in 1900-1920, before Prohibition, before the expansion of federal criminal law, before for-profit prisons and before prison guard lobbies.

For some reason, the U.S. is just an incredibly violent society. Our justice system has evolved in light of that.

Note that using the `not' and `null' functions instead of comparing equality to `nil' is good coding style anyway.
I'd just like to note here that the sysadmins know damn well when a dev tries to blame them for something the dev did ... and we NEVER. FORGET. So don't do that.

I'm not sure how to educate devs to think ops. Perhaps have their phone ring at 3am when stuff breaks? I think that would close the feedback loop nicely.

(Let me note again: I LOVE the devs who think operational issues, who think end-user issues - what customers are actually like - who think "developer of the whole thing from go to whoa" and not just "coder on my PC." As I'd hope we all do here.)
That doesn't work with 8.1 which the Surface 3 ships with.
perhaps, but assuming Sandstorm is a commercial venture and desires to make money, it IS their problem to educate prospective customers on their value proposition. we know what docker does.
What you are calling for is Argument to moderation[1]. Its a common fallacy, which asserts that the truth can be found as a compromise between two opposite positions. Working towards a goal without compromise with those who actively make that goal harder is not wrong.

When I have seen RMS labelled people as the "Others", it been when someone has done actions that is direct detriment to free software. If your goal is to build something, and someone else comes with a hammer and start tearing it down, I will give you some permission to be annoyed.

I love this approach. I am good at what I do, and appreciate the opportunity to prove it directly. Spending a couple hours solving a technical problem or writing an essay is much easier for me, not to mention sending a more reliable signal, than trying to figure out what networks / buzzwords / whatnot various people in an opaque organization are going to want to see. Not to mention, it communicates to me that the people doing the hiring know what they want and how to get it, which is encouraging.

I believe there is a happy synergy here, by the way. A candidate who welcomes this type of test -- who sees a direct work sample as the easy and efficient way to prove themselves to you -- is probably someone who knows their work is good.
The UEFI memstick works for me. But there's no EFI ZFS boot loader, root on ZFS is an open feature still.
Well, there's no way to distinguish real users from "real" users - getting 19 sockpuppet accounts on FB is trivial, so just target them and your mark.

As a bonus, if the advertising is per-view and your 19 fake accounts never log in, then the price of advertising to 19+1 is the same as advertising just to the intended target.

Archive Team says TwitPic is blocking photo downloads before shutdown
> But EP has not gotten us any closer to understanding “human nature.” Instead, its provocations about gender have distracted us from what is truly interesting—and radical—about Darwin. Several EP scholars argue that human nature was fixed in the Pleistocene Era, that modern culture is merely a flimsy cover for our cave-dweller minds. But a great deal of evidence suggests that evolution occurs at a much faster rate than evolutionary psychologists think.

On the one hand, this says that EP is wrong, and on the other, that there is a more radical and more interesting approach, more true to Darwin's thinking.

First, to say "EP has not gotten us any closer to understanding “human nature”" is a joke. At worst, it has at least eliminated some options. But the worst is very unlikely. Even if much of EP is wrong, many of the results appear to be solid. To so discount an entire field of science, done by very smart men and women, is completely unfair.

Second, the hint at a more "true-to-Darwin" approach of faster evolution, seems odd - just an attempt to say "EP is wrong, and boring - check this out!" First, if evolution is faster than we expected, then EP will adjust to that. It already has - we now know that things like lactose tolerance arose quite recently, and mental traits would not be surprising as well. Faster evolution will only make what these critics don't like about EP stronger, not weaker.

But more importantly, while the "frozen at the Pleistocene" approach is false - and already known to be false, no serious scientist believes that literally nothing changed since - it is also true to large extent. The Pleistocene is a huge amount of time, and in the short amount of time following it humanity diverged quite a bit - yet, we find humans extremely similar, mentally. From aboriginal Australians to Africans to Europeans to native Americans, mentally humanity is extremely close. That is very strong support that while clearly evolution continued after the Pleistocene, major things were already set by then.

Correct me if I am wrong, I am no expert on this matter, but it seems like prisoners get stuck in a loop - Make one mistake, you are in prison.

A Brief Look at brainfuck

"The last-known Union widow, Gertrude Janeway, died in Jan. 2003 in Tennessee. John Janeway joined the Union army in 1864 and was briefly a POW at Andersonville. The couple married in 1927, after waiting three years until Gertrude turned 18. John was 81.

The person thought to be the last-known Confederate widow, Alberta Martin, was born Dec, 4, 1906, and died at age 97 in Alabama on May 31, 2004. In 1927, at age 21, she married William Jasper Martin, then 81. Martin joined the Confederate army in May 1864. Upon her husband's death, she married his grandson from his first marriage."

Looks like Western culture standards aren't cast in stone. Or made in heaven.

You're talking out of ignorance, keep it down.

Guile-Emacs runs Elisp, not Scheme, and Elisp will remain the main Emacs language for a long time. Using Scheme will become a possibility and you can bet on some people starting it immediately, but nobody is forced.

Guilifying Emacs is not "pushed by the Guile guys," it's always been RMS's desire.

The "Emacs guys" is a rather large group of people, which is essentially a superset of "Guile guys." Some of them would love Scheme, others wish it was CL instead, others want to take Elisp on its own path to evolution. Guile offers an evolved Elisp, and Scheme as an addition. And of course One Day someone might sit down and implement CL for Guile too, you never know.

GCC, GDB, GNU Make, and some other tools can be extended in Guile. The Nix-derived package manager Guix which forms the core of the upcoming official GNU distribution is also written in Guile. It's becoming quite "relevant" on its own terms. But sure, Emacs would be a huge boost. They're both GNU software so it's a logical come-together if you ask me.
