Expected value calculations are very hard to do here, because you need to estimate the number of people who will be buying tickets, which you need to calculate the odds of sharing a prize, as well as to determine the prize amount. And estimation is really hard because there's never been a prize this big.

FiveThirtyEight[1] estimates between 550 million and 1.2 billion tickets will be sold. Their best estimate is 1 billion tickets sold, giving odds of sharing the prize at 97%.

This makes the Expected Value of a $2 ticket $1.34. If you bought one ticket of every number, you'd be guaranteed to win, but after splitting the prize with the other winners and paying taxes, you will have lost money.

The powerball is a crappy lottery -- most other national lotteries give out a higher percentage of their intake. For instance, Lotto 6/49 in Canada reaches a par expected value around the $40 million dollar range.

The real losers of lottery schemes like this are the people who buy tickets when the prizes are low.

This is fantastic. Are there other good programming challenge / games like this? I'd love to see a collection of other similar games.
The interactive polling stuff is neat, though it seems like it would occupy a lot more time in a presentation than the old-fashioned "show of hands" it's replacing (given the time an audience would need to pull out their phones and try to scan the QR / type the URL / send the SMS).

The on-device view of the current and upcoming slides (as well as speaker notes, and maybe even drawing) are also built into the Google Slides app's UI when you are casting to a Chromecast.

Everything is available. Not just plugins, but anything that runs in "fish". Well, that's the promise and the pledge. This includes whatever is the OMF barracks, and also Wahoo <github.com/wa>. If you know anything for Tacklebox, that will run in Fisherman too.

I am working on some tutorials and getting everything ready for the next milestone 0.5.0, but better ways to discover and preview the ecosystem is in the works and I vow to make it awesome.
Letting the computer choose randomly is not optimal, since the computer may choose one of the commonly hand-selected numbers. A better method is to build a list of commonly hand-selected number, then have the computer choose a number that is not in that list.
LIGO is very serious about doing blinded test runs, even going as far as writing the whole paper before they check whether the signal was real. There's only a couple of people in the entire collaboration who even know when the blinded test runs occur. In any case, this rumor has been going around for a couple of months, so if it's true, we should know soon. Between this and the LHC blip, I'm quite excited about the next couple of months.
Making promises in Tcl
From viewing earlier demos I believe it can be, possibly in real time. That said, reducing a voxel by half in each dimension yields eight times as many voxels, reduced by however efficient his algorithm for determining what needs to be visible and drawn is, so I think it might need to be quite an upgrade to see a big difference.

History of the Atlantic Cable and Undersea Communications
>> ... I did not consider his brother as anything other than an individual whom I had interacted with for the first time...

Agreed. And to continue his/her presumed train of thought, in my own words:

" Whoah! ... but now I realise that the guy I met was really somebody. He was Aaron's brother."

>> Your comment (to me at least) seems to suggest Noah wanted everyone to associate Noah with Aaron ...

I have no idea how you arrived at this interpretation of my comment. Though I can agree that if I had been making such a suggestion it would have been unfair to Noah.

Anyway, I don't believe it is worth pursuing this further. We have at least demonstrated that, in all good faith, it is easy to interpret the same thing in different ways.

I've been crucified in irc for suggesting moving away from samba and towards using chef/puppet/ansible/salt to manage windows user accounts (if coupled with pxe booting for dynamic image loading on user machines...) I still like the idea.

All of the above is correct.
Introducing Uber Trip Experiences
thx.

An elevator once dropped me one and a half floors with open doors (both, floor station and cabin doors). I think the cable slipped over the transport wheel. Felt funny in the stomach, but we all kept standing when we hit the end-stop in the pit. "safest way of travel" huh!
Well, given the amount of tickets, I doubt it.

Let's just say you found out nobody won on Saturday night and started your plan right then. It takes about 10 seconds to slide the card in and get a ticket, but let's be generous and say you can do a 5 number card every second. That's 58,440,268 seconds or 676 days 9 hours 24 minutes 28 seconds which is a bit beyond the limited window of Saturday night to Wednesday night. This does not count consumables, consumable reloading, or possible break down of the machine. It would take well over 200+ machines to make the deadline at 1 per second or 2,000+ machines for 10 seconds per ticket.
What's the difference between the several hundred million losers of this draw and the tens of millions of losers of the draw a month ago?

You seem to be saying there is one, but I don't get what it would be.

(I bought a ticket, I think it's fun to buy one once in a while, so I'll be one of the losers tomorrow)
I think it's perfectly rational to be upset in the case where coworkers get the paid the same as you or more, yet are in your eyes less productive, competent, or otherwise valuable. Pay signals how much your employer values you, and therefore indirectly your job security. If your hard work goes unrecognized on the balance sheet, it'll probably go unrecognized when times get tight and they need to lay people off.

Wanting to feel valued in one's "community" isn't comparing yourself to others, it's a basic human emotional need.
You could have all of the students scan the QR code or enter some text at the beginning of the lecture and keep a session running so that the voting controls work throughout the lecture.
My first thought on reading this is that the cabinet decorations are almost always subconsiously ignored as noise. The fact that SOs spotted the directions while the players didn't seems to confirm it as well. I say subconcious because most people wouldn't realize the heuristic they were following until it's pointed out to them and probably wouldn't see their mistake even then.
Thank you for pointing me to the porting guide doc! If only they'd linked to that in the article ;)

>I've found that for my side projects (I'm still a student) Docker has vastly decreased the pain in deploying my projects. I used to have "but it works on my machine" moments but now using the same container in production is super awesome!

Thats a far stronger reason to use Docker - as I'm sure people have wrestled with this issue when trying to use Capistrano/Grunt/Ansible to deploy as well.
I just can't see any of that happening in the US, our society is too mean spirited. You must prove your worth in order to have what you need and want. You must prove your worth to get education and health care and shelter. If you aren't contributing according to expectations, you're on the street, except you aren't allowed to "camp" there.

I live there, and I think you are not far off the mark. Why?

In China, 1.4 billion people basically cede total responsibility for fiscal literacy and policy to the government, almost no questions asked (ever). That is a very different reality from the west. Hence, you cannot apply traditional western modes of analysis to the mainland Chinese domestic financial world.

I believe that such a perspective is in keeping with Soros' philosophy, ie. viewing the market not via false analogy with Newtonian physics (ideas of 'equilibrium', etc.) but instead as a large group of imperfectly informed actors: crowd psychology.
I'm pretty sure they have before and would again for an experiment.

Seeking Immediate UI Visual Designer for Web Prototype
We are a small, pre-startup Product Development team that has been working on a web project, a how-to and help guide for a large social network, for the past 3 years.

Seeking a visual UI designer, that can begin work immediately. The job entails creating web flat-design page layouts and revisions to existing Photoshop files, working under our Design Director in rapid iterations. However, there's huge room for you to design/influence 3 major components of this first "prototype". It would be at minimum 20 hours a week, for a month with the good possibility to extend longer.

Please submit resumes, questions to uxstudioSF@gmail.com. Thank you!

I don't know anything about computer science or statistics, and I never once thought this course or machine learning in general ever had anything to do with actual learning in humans. The distinction between this and cognition is pretty clear, and it would be obvious to anyone 2 minutes into the first presentation.
Agreed, and thanks for bringing this up. This is why Tungsten and HMI lighting is still a thing. Remote phosphor lights from Cineo are supposed to address this, however. But this would not be used in a residential setting, more for commercial lighting situations.

Funny they refer to it as "business logic."
It's worth noting that in China, including mainland China, homosexuality is not seen as much of a taboo as it is in western cultures, whilst there are many on here that live in liberal cities, much of the west is still uncomfortable with the premise.

E.g. – The MP from my hometown (Glyn Davies: http://www.theyworkforyou.com/mp/24739/glyn_davies/montgomer...) has consistently voted against same-sex marriage, and many in the area where I'm from would likely agree with his vote.

It's strange to think that in China, of all places (because of what we read about censorship, and other conditions) would have a more understanding attitude towards something that on our side of the planet is still seen as undesirable by a probable majority. There aren't many western corporations that would have gambled on the purchase of Grindr, and not because it can't be profitable, but because of how it could be interpreted by shareholders and society at large.

I don't have the measurements, and the valuations of Tinder are generally outlandish, but it would be interesting to compare their valuations based on membership numbers, purely to see which orientation (based on the mean) the Chinese market values more highly in this industry.
Open source is super amazing (except for when it isn’t)
The broader point is that the user was using an external service (Yahoo chat) via the company network, not (for example) just via his company email, so the title is bogus.
In the way you responded and described your experience, I think the term I should've included, at least from an academic basis, is that of "code switching" because it's a pretty interesting concept to me. The big key was the 'work' versus 'home' concept of self. It's totally reasonable to want to compartmentalize, I think it's pretty ingrained in our species, so talking about it as a fact of life is pretty useful.
Perhaps I read their interactions differently, but even their "I need the springy jobber" and other more informal statements seemed far more professional and what I'd expect from a career astronaut than "I'm going to do the iron man thing".

My original comment was more directed at the actual crisis portions of both the movie and Apollo 13 (around the famous "Houston we have a problem" line) were drastically different. I certainly grant that a movie might not be as exciting if crisis resolution was largely reading checklists out of books and remaining exceedingly composed given the circumstance, but I'd find it a lot easier to buy into than the cacophony of yelling and cursing that took place at multiple instances during the movie.

Something additional and more tangible I remembered while writing this, I found myself agog at some of the items they had on mars; the commercial grocery store grape juice bottles were some of my favorites.

Edit: I'm normally not one to comment on this, but of all the things I've ever said, I had no idea disliking this movie would attract the silent downvote brigade so aggressively. I find this both interesting and entertaining.

Okay hold the US government for aiding in Saudi Arabia's human rights abuses.

I don't know whether to cheer for things like this, though I do support works for improving human rights. For the most part they seem to be drops in the ocean of human rights abuse. And I don't know if it's doing anything to stop those abuses or just a control mechanism to make us feel like we are accomplishing something... while the biggest abusers and their supporters continue scot-free.
Hrm, tough question. I heard this advice many years ago, though:

Total agreement. Linux on the mainframe is really silly beyond utility purposes, whoever the business people are that convinced senior IBM management otherwise really pulled a fast one.

POWER8 is designed for UNIX, and adjusting for certain parameters goes beyond what x86 servers can do in the same footprint and reliability. Price is approachable to people who need the reliability these kinds of systems can provide. IBM systems have grown a lot in common over the years, with AS/400 or System i and RS/6000 or System p melding together, POWER8 kit has a lot of mainframe inspired RAS features.

Is that really the case? I think some citation would be nice. For example the refugees in Europe often have a smartphone among the very few things they take along on their journey, simply because is is essential to their survival. I mean they have nothing, but they have a smartphone. And some smartphones have become really cheap, too - (there is Android, you don't have to buy an iPhone).
I've noticed much less awkwardness and resentment when people are faced with non-French speakers in general - both in stores and with regular people. I'm not sure about how things are in the workplace these days, though.
Yes, you can do this.
So what you are saying is that there is an enough of an increase of demand attributable to desirability of particular areas (Manhattan below 110th) that new construction does little to bring down high prices.

But without that new construction, those seemingly high prices would be even higher than they are now, unless you assume that the increase in demand is itself a byproduct of the new construction.
This is justified in the book as being for thanksgiving dinner, iirc Mark goes as far as explaining how they where treated that still allows them to grow later.

Interesting twist, as data itself is not under copyright, but a compilation may be. Is a CAD file such a compilation, or just data formatting? I'm not sure.

(However, I do blame The System for this uncertainty. I wish it'd err more often favouring the copier, instead of the rights holder, if that would make everything simpler.)
GraphiQL: GraphQL’s Killer App?
No, I don't have any significant Python2 codebase. I'm making my own judgement calls off the situation and facts as I see them. I wouldn't build any project in Python3 today, because the prod-ready PyPy option isn't there which adds CPU performance as a Python feature and removes the GIL.

Just because you agree with part of my post and arguments doesn't mean you have to downvote. I had the GVR quote about semver to directly responded to and added to the original post, which is more than most comments.

Anytime I post something critical of Python3 it seems to be a big tug-o-war between those who want to shame me and those who want to show approval. I do it because someone has to say this stuff because I believe the silent majority sees it this way and I frankly find the vocal Python3 promoters to be the loudest of the bunch. There's nothing wrong with other viewpoints unless you're wrong. :)

By the way, Mark Lutz is well respected. He has been teaching Python for decades.
pfSense might be fine for home or small business use, but I wouldn't recommend it for datacenter or medium/large enterprise use.

It is primarily GUI-driven, which won't cut it for automation, version control, or some auditing.

AFAIK it is still based on m0n0wall. The init scripts are written in PHP. There is (or was when I used it years ago) one big PHP script with a bunch of includes. If any part of the PHP script fails the rest may fail.

This led to a bunch of problems with packages. For example I installed the RADIUS package through the web UI, decided I didn't want it, removed the package through the web UI. Removing the RADIUS package removed something the large PHP init script was trying to include, which led to the script exiting immediately with an error.

The PHP script was also reasonable for loading the firewall rules, but it exited before loading the rules. Which resulted in a booted internet gateway with _no firewall_ (allow any).

This aspect of pfSense may have changed, so I'm not trying to hate on it, just trying to point out that it may have shortcomings for some use cases.

I've managed straight pf on OpenBSD for gateways/firewalls. pf is very nice to work with, much nicer than iptables/tc for internet gateways. But that also won't scale to large enterprises or datacenters . The amount of data is too much for OpenBSD and generic hardware, at least as for as I've seen. At one employer the largest Palo Alto Networks firewalls couldn't handle our office network traffic, they had to be replaced by firewalls from another vendor.

So it really isn't fair to compare FortiGate firewalls, some models of which can do 300+ Gbps, with 40/100 GbE ports, to a little box running pfSense.
Tabs don't show you exactly how to position your fingers, only where to press the fretboard. There's still some skill required in figuring out which finger to use for each string, and the best finger sometimes depends on the size and flexibility of your hands.

Cost per transistor is still dropping, but transistor count is skyrocketing as Intel adds cores. Their flagship Xeon CPU has 18 cores and something like 5.5 billion transistors.

New CPUs during the clock speed doubling era had moderate increases in transistor count to accommodate new features. Now that clock speed increases have stalled, adding on more stuff is the only way to differentiate new products.

I've used consumer embedded hardware encoders in the past (quicksync, nvenc) using OBS, and they simply could not get enough quality at a streamable bitrate. They were however amazing to capture (near-)lossless recordings of an application at no performance cost.

I assume that dedicated hardware encoders/capture cards do not suffer from this, but it would be amazing of high quality streaming becomes available to the public without requiring dedicated hardware.
Philae was a mechanical failure that had little to do with the shape of the comet - its harpoons failed to fire.
