Well.

* Can it let me start jobs manually?

* Can I defer their scheduling programmatically without editing a file to comment it out?

* Can I add or remote new jobs programmatically and atomically?

* Can I ask it about the status of a job?

* If a job fails, is it retried, up to a limit?

* Can I give it a time budget after which the job is killed?

* Can I give it a resource budget (e.g. CPU usage)?

* Can it log the output tagged with an identifier that identifies the job uniquely across time?

* Can it notify me by some programmatic mechanism (so that I can pipe it to a webhook, say) if a job fails?

* Can I programmatically start jobs, edit jobs, etc. from a different host?

* Can I ensure that only a single instance of the job runs in a cluster, if multiple hosts have been configured with the same job?

* If the job runs so long that it overlaps with the next scheduled period, can it ensure that the next job doesn't start yet?

* If the job forks, can it ensure that the children are cleaned up?

These are some of the features that I want from a job scheduler. Yes, some of it can be cobbled together with wrapper scripts, manual cgroups, and so on. But I don't want to write all of that.

Shell scripts are brittle. That's hardly debatable. You can write solid shell scripts, but people generally don't because it takes a lot of effort and arcane knowledge to do it successfully.

A lot of people don't know about classic safeguards such as "-e", "-o pipefail", exit traps and so on. Some of the safeguards you want are hard to do safely and atomically.

Unix has a nice pipe system, but shell scripts that need to drive a lot of things invariably mess it up because everything pipes to the same place. You get errors and information output intermingled and there's often no way to tell who emitted it without going step by step.

Throughout my 20+ years of using Unix variants, shell scripts and "shell-scripty interdependencies" have always been a source of problems, usually related to things like escaping, quoting, option parsing, alias expansion, variable expansion, bad toolchain detection (e.g. assuming your "ls" is GNU), ignoring exit codes, bad output parsing, etc.

"find | xargs" works just fine until the day you encounter a file name containing spaces. Then you do "find -print0 | xargs -0" and you're happy until the next edge case comes along that touches on space handling, of which the shell language family is rife. It gets worse when shell scripts try to be nice over SSH.

At least languages like Python and Erlang have first-class support for primitives, even if their dynamic typing leads to a lot of potential situations where the runtime parameters aren't what the author assumed, and things blow up because someone didn't sufficiently duck-type. I'm not a huge fan of Go, but Go is a surprisingly good fit for command-line tools, and its strictness and static typing helps avoid a whole class of errors.

I love shell scripts, and I write them nearly every day, but I would never build an OS on top of them.
I have really small hands, like XS glove size. I run with a 6s just fine, up to 45 minutes. Any longer and I'd probably get a waist belt: http://www.amazon.com/gp/product/B004QQTDA2?colid=1JE32OIQBN...
I find it interesting that, in the third graph (commits/dev), the Mozilla line gets a dip to about half its previous value as the Chromium line shows up, somewhere around mid-2008. Post-dip the jitter also seems to decrease.
I've had to use my reserve twice. I think it was the most focused and hardworking I'd ever been, before or since.
Back in the '80s I heard a rumor that one of the many large defence contractors who also had a fair amount of civilian work had many of their workers filling out two time cards (both for ~40 hr/wk) – one on civilian contracts, one on military contracts.
Good clarification, and I should say that my comment was more intended to address the broader objection to having abstaining members, yet still calling quorum & unanimous consent - rather than evaluate the specific Theranos situation. IANAL and there isn't enough info in the article to even really do that.
Any chances that this nice tool will be open-sourced?

It would be really convenient to use it as an intra research group discussion on papers.

another couple of rogue engineers? or were it the same ones who just happened to change the specialization from diesel to gas? Or how about some fairies ... err ... hackers who hacked into the VW network and put the cheating codes into the engine software? I can't wait for the spin. Some PR agency specializing in crises will make a killing here :)
I think when you put it in perspective like that it's STILL stunning. 800m is a sizable fraction of the DoD budget keeping in mind that the other stuff is maintaining a worldwide military presence on land sea and air and 800m went to a gas station.
It is a story gaining traction - you will hear a lot more about Theranos. Not because they are worse in any practice than the rest of the herd, but because they have spotlight. One of the things about getting past 30 is spotting patterns in the newscycle. Theranos is indeed a juicy target so expect a lot of dirty laundry to see light of day.
I am by no means obsessed with death but for as long as I can remember thinking about dying I've fantasized about going out like this:

After reaching a point where I feel like the end is nigh, and/or my quality of life has sufficiently deteriorated, I skydive from 20,000 feet into the mouth of a live volcano. No parachute (obviously).

Not sure why I see this as romantically as I do but I can't think of a better way to go.
Subscription cancelled.

Damn. NatGeo was a big part of my growing up. I had a subscription gifted to me as a young kid, and I read every issue cover to cover, until I was 18. Mostly, I've continued, though not every issue.

It's hard to describe the quality and overall breadth of writing and the clarity of presentation and how that gave a young person a solid grasp on the world, the peoples in it, etc...

Sad day.

And an angry one. This absolutely didn't and shouldn't happen. Perhaps that staff can build something new. I'll sign up right away.
Shareholder agreements can define 'Unanimous' in any variety of ways. So long as the agreement is approved, it can supersede Deleware shareholder laws.
It's rare to see a more right wing opinion being dictated in a way that is thoughtful or halfway intelligent. Yours is beyond halfway and I'm being serious.. good post.

To answer your question, we need these programs because just 100 years ago some people couldn't read and write. With public education K-12 and public universities, I'm much better off than my own family 100 years ago, before the gov't started these social programs.
I'm a product of public education all the way through, and I'm very thankful as it was subsidized by others. I know the program works, and I'm happy to support domestic spending.

I'm in agreement with the parent though that offensive military spending (which standing armies always leads to) is flat out a bad idea and wrong[0].
My great grandfather served in WW1 in the trenches of France, fighting our homeland (Germany). His son-in-law, my grandfather, was shot multiple times over Germany in WW2 by flak as a gunner in a B24 in the Army Air Corp. He flew enough missions that his chance of surviving the war was 10%. The other was a Marine in the Pacific. But we as a family 'serve' no longer. I changed my mind about going to Iraq when one of my grandfathers told me we had 'no business being over there'. And the other said flat out, if the military comes for me, that I'm to go to Canada.
I would never disobey those men which I respected so much.

So for me, the principled reason would be just looking at education alone, it makes a better world for all of us. Better quality of life, more opportunities, and an advanced economy.

No matter what, I think you must first build a knowledge graph. One example that was recently posted to HN is https://news.ycombinator.com/item?id=10468732. Maybe it could be crowdsourced or generated by mining Wikipedia.

Then you need some way for people to find out where they are on that knowledge graph, and a recommendation engine for where to go next. I also think it would be useful to mix in a few random topic nodes that are some number of hops away from a person's current knowledge, plus occasionally a completely random topic of the day.

But that's just the most trivial beginning to an enormous problem.
Exactly. The ideal emissions would be 100% H20 and CO2. I suppose a string of chemical reactions could be engineered to make the emissions nothing but water and diamonds, but until that happens, some mixture of CO2 and water is the ideal.
Wow... Just wow... I bet Fox-type "news" and "research" will be shown about some fox-type bullshit stuff but claiming National Geographic-type truth of it.

Suppose I just want to use my Nvidia card in GPU mode (i.e. monitor only connected to Intel integrated video), does the X.org version still impact me? Or does the 'nvidia' proprietary driver somehow pull in Xorg dependencies even when not displaying anything?
Headline says "entire staff" and needs to be changed. . . Nat Geo laid off 9% of staff.

http://www.usnews.com/news/business/articles/2015/11/03/nati...
Sigh. Title should be edited. Article heading states: "Rupert Murdoch Takes Over National Geographic, Then Lays Off Award-Winning Staff"

According to source, it's about 10% of staff.

The article says that "all" were laid off. It's sources say otherwise.
The idea sparked when I went to a tech conference of 1500 attendees and there was no way to chat with the attendees.
This is due to the dollar.

It's not a coincidence it's all happening simultaneously globally. For the same reason, every GDP on earth simultaneously skyrocketed (priced in dollars) as the dollar lost value in 2002/03, as the US Government began running large budget deficits under Bush.

It's causing the mess in China to get worse, by pulling capital out of China more rapidly. It crashed Brazil (check out when their unemployment began to soar, exactly when the dollar run began [1]). It crashed Canada and also hit Australia hard. It caused Russia to lose 1/3 of its economy, and is bleeding off their reserves and emergency fund; and the worst isn't over yet. The strong dollar ended the USSR by tanking the price of oil, and caused their crisis in 1998 as well.

The same thing happened in Asia in the late 1990s, when the strong dollar crashed numerous economies there. This time is worse in terms of sheer damage, as those Asian economies are far larger today (as are Canada, Australia, Russia and Brazil).

Every day the dollar remains strong, things will get better for the US and worse for almost everyone else. It has already pulled trillions in capital back to the US, and has boosted real US annual purchasing power by at least $2 trillion in just 18 months. The US has gone from #9 or #10 in the world in GDP per capita in 2014, to #5 on the IMF's projections for 2015, due to the dollar.

Generally speaking laws supersede agreements, not the other way around. That's their whole purpose. Certain things can't be done and certain rights can't be forefit if specifically disallowed by laws
I just find it easier to setup and maintain, really. Philosophically, they are similar, with Fedora being minimal, but you get things like gcc, python, and other items by default, which is nice. Fedora doesn't come with LibreOffice, games, or anything like that.

I only used yum on CentOS, and I thought it was okay. Fedora now comes with DNF which is pretty close to pacman.

Don't get me wrong, I like Arch a lot still and have no complaints, but I felt like Fedora struck a nice middle ground, and is, by default, very close to how I set up my Arch system anyways, even closer with the LXDE spin.

edit to add: I still use the Arch documentation for just about everything. That's one area that no one can say Arch is deficient on.
They could have started with closed source itself right?

The other day I was considering switch my mom's PC from Windows to Linux. She is the type of user who do almost everything on the browser (Gmail, Google Docs, Google Photos, YouTube, Netflix, Spotify, read stuff), off the cloud maybe some MP3, photos and documents; I mean, no command lines, no read tutorials to do something, no annoyances, easy to give up on something with too much steps.

I was considering installing the distro Elementary OS or Ubuntu. Do you think that Fedora can be a good option too? Which of the three is best for that user case?

A thing to consider is that her laptop is a bit old, from 2005-2010 I think. I remember that has 2 GB of RAM. She upgrade from Windows 7 to Windows 10 and say that now runs faster than before. The new OS shouldn't run slower than Windows 10.

I'm on a decision paralysis because on Elementary OS I see most simplicity (OS X in mind), in Ubuntu more speed and trust that is not going to crash (large user base), and now I discover Fedora and see that can have a good mix of both.

Let me know what you think. Thanks!

Ah good call, I missed that part of his description.

Wow, a bunch of us must have had the same computer. Mine even came with a 1X CD-ROM. Unfortunately I found out the hard way that my copy of 7th Guest didn't run well on it. The animation was super choppy, since it recommended a 2X CD-ROM... :-( I don't recall if I was able to return the boxed software to the store.

Luckily, Microsoft Encarta and Microsoft Dinosaurs, which came with bundled with my Gateway 2000, ran fine.
I think that the assumption is that you'll always get the best possible price on the book, so consumers won't worry too much about pricing.

We don't have Amazon as such a big influence in my country, so I'm curious - does the price of a book on Amazon impact your decision to buy it?
The state has filled the power vacuum left by the church and thus taken on the role of social welfare provider.
A nuclear researcher from iThemba Labs gave a talk at University of Cape Town shortly after the Fukushima accident.

1. During his talk, he mentioned that nuclear plants are designed to have a very low probability of Chernobyl-scale failure, and that the current rate of Chernobyl-scale failure given the number of nuclear plants in production is roughly 1 every 20 years.

2. He eventually concluded his talk by saying that we should double the number of nuclear plants in production around the world to remove our dependence on coal.

I asked a question at the end of his talk, given point 1. then point 2. would mean 1 Chernobyl every 10 years. He was completely dumbfounded. He had never combined his ideas with simple probability theory. One physics student present then said angrily: "Yes, but we will get better at building nuclear plants."
Where are you getting $1.9T? The numbers you cited don't seem to back that up.

Social security was $857B, but is entirely self funded through the payroll tax, Medicare was $519B, and the rest of the social safety net programs were $370B[1].

Also, I would quibble about the defense number. Missing appear to be $151B for veterans affairs (part of the price tag for our wars), and the interest on debt from past wars makes up the bulk of our interest payments of $223B.

I think this is a systemic problem in Afghanistan.

I've heard that once a contract is put up for bidding by the government, someone buys it out, and sub-contracts it out a step down the ladder. The sub-contractor sub-contracts it out again another step, and so on.

until eventually a local is taking a picture of some other well as proof and everyone gets paid and nothing gets done.

I couldn't comment on whether this has any truth to it, I've fortunately never been to Afghanistan and also I don't know anyone who's been.

after hearing it, it's hard to imagine things working any other way, looking at the fruit of the time and money.
And that was after Dell and Gateway did something similar to Compaq forcing them to change.
With the expectation that if you like their inventory, you'll pay for the convenience and service in store. If you receive a benefit from that convenience and service, there's no way to contribute to the existence of the store outside of purchasing their product (I suppose you could donate straight to the owner, but that's messy).
And that's why trading needs fees, otherwise craziness follows.

To be both somewhat insightful I provide a small correction...

> Ultimately, the predominant educational system and it's preeminent methodology, have become about competing for progressively smaller numbers of seats in progressively better lives...

One of many reasons I have put off having a child, the financial burden of giving a child a 'good' education, is considerable. From the purely academic component of quality teachers, to the social component of creating an environment where their interaction with other children is beneficial, neither of these comes cheap.

I'm not after much, just well paid teachers who stay passionate while they teach, a class size where they can give each student enough attention, curriculum that allows the child to 'surge forward' when driven by curiosity and be rewarded for their work not punished for not doing 'this weeks assignment', and enough other children to interact with so they can develop social skills. The last one is the tough bit, all the others can be provided by home school with or without using private tutors or paying for a 'personal teacher'.
I was thinking tighter integration than that.

Imagine if ssh private keys could be stored inside 1Password. It would become a ssh-agent replacement.

No real reason to leave ssh private keys scattered on different user directories anymore.
I'd recommend Xubuntu LTS. It's has Ubuntu's big community, is fast and stable, and comes with a familiar interface.

Off the top of my head:

* Therapy off and on for about 20 years. I got something from all of it but the last five years in particular has been great. Currently I only go a few times a year, but for about a year I went once a week. $135 per session.

* Various prescription drugs, the most impactful of which has been Zoloft. Bit also Chantix to quite tobacco and Antabuse to help me with alcoholism

* Membership in mastermind groups - some business-oriented, others geared toward personal development. Usually there is at least one meetup/retreat involved. In 2013-15 I did one retreat per quarter. That group cost me about $10,000 a year in dues plus travel.

* Fitness classes - $150/month for the last five years or so

* Quality of life stuff like owning a luxury car, living in a beautiful place, international travel at least once a year, and so on.

I truly hope you are a billionaire, because once your Randian utopia comes to fruition, you will need private armies to protect you against their Blackwaters and Pinkertons. Because they'll come for your assets. Count on it.

Don't believe me? Look at Russia. See what happens when oligarchs challenge the supreme oligarch? Their assets get "nationalized", and they are imprisoned. That's best case. The less significant ones catch odd diseases strangely similar to polonium poisoning...
