Statisticians have spent time thinking about the right way to deal with these sorts of problems for a long time: https://en.wikipedia.org/wiki/Sequential_analysis.

Funnily enough, the page they reference for calculating the right sample size actually talks about sequential analysis, but AirBnB doesn't mention this in describing their solution...
The bond rating will affect the stock by proxy, so it's alright for me. But even the bonds have a decent chance of maturing. They're convertible bonds too, not just standard interest bearing ones. So really, you can treat them more like stock anyway.

The question is "Do I see Tesla as still being here in 5 years?". No doubt about it. Well, in one form or another anyway.
> Actually the submarine program in question (the SSN-774-class procurement program) is one of the most successful defense acquisition programs in U.S. history, as far as cost performance and compliance with contractual deadlines and milestones.

So what? The Virginia class procurement program is meant to maintain nuclear submarine capabilities in two shipyards instead of one so we get to pay for that inefficiency while GDEB and NNS regularly get applause for cutting costs in a program plagued with lots of low hanging fruit.
There is no description of how it's supposed to work.

When I log in with my github login all I see is a mostly empty page with no explanation of what to do next.

So as far as I can tell, all that's implemented is "log in with github". I don't see any blogging functionality.
You rant about "follow the law" but who exactly is being hurt? The person making rent off his/her extra room? Please give examples or real harm rather than, "follow the law" statements. I suppose you're the kind of person that'd turn in Ann Frank. That'd be following the law.
The excel database functions (DAVERAGE, DCOUNT, DGET, DMAX, DMIN, DPRODUCT, DSTDEV, DSUM, DVAR) give you about 90% of what you want in a database with a query "language" that's simpler than SQL.
I never understood how IRC was somehow not accessible. Connect to a server, join a room, (usually from a helpfully provided list), enter text and other people see it. Those are the basics, and my gran could understand them.

It's no more difficult than browsing the web.
That's pseudo-persistence, and it's only as stable as the client or bouncer. HipChat and Slack provide actual, stateless history, so you can reboot, logout, sign in from a mobile device, whatever, and pick up where you left off, with notifications in the meanwhile.

Other than OS X?
Similar for me and mine. We ran out of free users, hired a new guy and couldn't add him in. Someone else suggested Slack, and until this announcement, haven't looked back.
I'm one of those weird developers who loves PHP despite it's warts, and pushes the poor language to it's limit. I love the stuff that's happening in the community (PHP-FIG, the PSR standards, Composer/Packagist, and the like).

The thing is, that is all being achieved despite how badly the internals is run. Seriously, I tried to get involved and was turned off entirely by how it's run as an "old boys" clique where new developers and changes are considered enemies. It's really sad, and I think PHP could become a much nicer language overall if that changed. Some people who are far smarted than myself have the same opinion too, so it's not just me...
HipChat is incredible compared to IRC.

Out of the box you get:

1. 1-on-1 messaging
2. Private and public chat rooms
3. A client that works on mobile, desktop, and web.
No matter where I am, I'm connected to my team.
4. Persistent and searchable history.
5. Real-time notifications if someone mentions
you while offline.
6. You can copy and paste screenshots directly into
the room. We use this all of the time for gui
mockup discussions.
7. Integration with most online services like
GitHub, etc...
8. Easy file transfers.
9. No servers to manage.
10. Easy user management.
11. Video calls.
12. Voice calls.
13. Screen sharing.

Most importantly, it all just works. We could get IRC to do much of the above, but it'd be a hodgepodge of a solution and require someone to spend time setting it all up and maintaining it. At $2/user/month HipChat is a no-brainer. Why waste engineering resources trying to solve problems that someone else already solved for us?

Edit: And custom emoticons. Can't forget those. That's the best part of HipChat.
I see no reason why they're not compatible -- indeed the iPhone template employed comes from Origami.
True, but it has dock badges, native Notification Center notifications and keyboard shortcuts for navigating chat. That's close enough to native for me.

Agree, it is all about the getting to know and that probationary time period builds the confidence on both parties about each other. I'm interested about this approach and like to give it a go. Please contact me carcruz1976 [at] gmail.com.
HipChat is great, but I've found myself much more often on JabbR (https://jabbr.net/) to be honest. Might be because I am a sucker for SignalR.

JabbR is also free to use, you can have private team rooms if you so like and it integrates with a bunch of auth services.
The IT Security Caveman
I'm just hoping Apple offers up a new release of Quartz Composer which incorporates the Origami patches and fixes a few more bugs. Speeding up live renders would be a bonus, and I'd cry tears of joy if they figured out a way to openly release their internal Core Animation prototyping tools.
A better way to say that would be: erroneous causation assigned from from mass correlation of personal data.

The automation to rapidly sift data and identify correlations is coming along nicely, but I fear that the capability outstrips the ability or desire to assess the correlations and figure out if they actually point to any sort of causality.
Don't worry. Apple ignores Quartz users too. :D
Do you get paid for keeping that Nielsen box? That is a doubt i've always had.

An idea I have for the late Idea Sunday: a mobile app where the user let it on next to him while watching TV and it recognize what is he seeing by the sound. No need for input or action by the user.
Looks like you just need to fork the repo they've created or have a repo called 'gitpapers-blog' and login with github, and the posts will show up.

Looks like it was just a fun learning project for them.

I'd say it'd be helpful to add to the documentation that you have to login to gitpapers after forking or creating the repo in the explanation for clarities sake.
Why's that? I use Chrome Application Shortcuts for Slack and it essentially creates a task bar shortcut, and works with desktop notifications. It's currently missing background notifications, but aside from that, there's no appreciable differences between it and something truly "native client".
I've set up an IRC server before and tried convincing a moderately technical team to install Colloquy and jump on. I will happily trade the features of Slack or HipChat for the simplicity of IRC. Persistent rooms alone (with zero config, no bouncers, etc) is worthwhile over vanilla IRC.
Awesome, I was actually looking for something to do this earlier today!
I don't think it's freely available. A search like that will often turn up a good PDF copy though.
If a Panda Rolled Out, Would the Internet Notice?
google is not the only search engine.
If you haven't looked at Jekyll, I'd look at it and see how they're doing things like post metadata using yaml. It's definitely not something to replace the existing static blog generator they have, but it's a cool project for just tinkering with things like the github API.

IF you want it to be a truly usable project, I'd say you need to make it themable and not depend on parsing the file name for the post titles.

Exactly what I'm talking about! Their one child policy has already been eased: http://online.wsj.com/news/articles/SB1000142405270230328990...

Either a) the author knew this and didn't think such a major policy shift was worth addressing or b) was ignorant.

This is what I mean - the article was poorly written / researched. China has many problems, the article doesn't have any substance. It's divisive, and inaccurate in several key "facts".
Japanese numbers used to be delimited with commas every four digits, like so: 1,0000,0000 due to the largest common single-use (i.e., not a combination of a small number plus a large number as in "hundred thousand") being 10,000 (万, man).

Nowadays I've only ever seen US-style commas and it's hard to even find a reference to the four-digit commas online.

Cheap Intel-based Android tablets get real
Wait, how is Wikileaks related to Snowden?
Yeah. Simpler English will help with dumbification of the populace. People can't spell already anyway. Idiocracy in the making!

Anyway, it's really pathetic that people get offended by words. Spoken language is one of the most effective tools of manipulation. If you feel bad, just because you heard the "N" word or "master" or whatever, you know what, you're weak and well-suited for one of the most ancient tools for exploitation. Men who go in jail or kill somebody, just because somebody used the right word to trigger their irrational and destructive behavior - those are weak, not manly.

Anyway, ignore the words, focus on the meaning, but, I guess, it's too hard for some! And those don't even get when you're truly offending them with phrases their simple minds cannot process - sarcasm is not for everyone!

As someone who has worked rather extensively with both, no, they give a lot less than 90%, and for even fairly simple uses they are often more complex to use than SQL.

The economic multipliers of the defense contractors are horrible compared to, say, DARPA/NASA and infrastructure investment. The trickle down of technology is slow and the industry has been growing more and more bloated since WWII.

Manufacturing in the United States accounts for over $3 trillion of the GDP and dwarfs even China's industry. We don't need $500 billion or more a year of defense spending to keep our capabilities maintained and we certainly don't need nuclear submarine manufacturing capabilities in two shipyards.
The world didn't, but Windows admins did. It's allowed a lot of people to migrate away from legacy VBScript. You don't want to program in VBScript, trust me.

Following the law would mean not renting out their properties in SF. People clearly find value in doing so. If AirBNB goes away, the same owners will just switch to Craigslist or the next alternative.

Learn to deal with change instead of bitching about everyone who bucks the trend. I assume you feel the same way about Uber and Google Fiber displacing all those taxi commissions and telecom monopolies.
Why Medicine is Cheaper in Germany

Thanks for your informative comment. I know less about HPHT diamond synthesis, and may not understand the cost structure of that technology as well as I would like.

I agree re the current high capital cost of CVD diamond synthesis equipment, but I'm pretty certain it need not remain so. For example, in microwave plasma assisted diamond CVD, significant slices of the cost pie are in the microwave power source and the deposition chamber. The former tends not to take advantage of 2.45 GHz consumer sources and is, I think, overpriced in $/Watt compared to what it could be with some additional electronic design work. The latter suffers because diamond microwave CVD chambers tend to be one-offs. Building them in hundreds or thousands would allow lower cost manufacturing technologies to be used.

Power costs are an issue, but there are ways of extending the lifetime of atomic hydrogen, which is a key cost determinant of CVD diamond. Labor costs will be reducible to the extent that CVD processes can be automated, which I regard as largely a matter of getting reproducible processes in hand. When you have a predictable process, you can automate it.

I concur it will be awhile before my Replicator 2 can spit out a diamond filament. But I think the current manufacturing cost of diamonds is far higher than what it might be. The missing link is somebody willing to fund the volume manufacturing process development.
Well, that's not mandatory, so it's those companies own problem. Mandate the technical debt, and it'll be everybody's problem.

When Brazil was announced as the host for the 2014 World Cup, my wife (from Brazil) and I were ecstatic. We planned to attend and were excited that the country would have to improve its infrastructure to accommodate the international soccer fans.

As 2014 approached, we noticed that Brazil was doing frightfully little to improve transportation, healthcare, and security. Instead most of the money (that hadn't been siphoned into the pockets of the corrupt) was used to build 12 extravagant stadiums when FIFA made it clear that only 10 were necessary.

As a result, many Brazilians are fed up with their government, and crime has only become worse. Regretfully, we decided not to attend in order to keep our little son from the higher risk of danger. My wife's family members first believed that we were too paranoid. However this year, nearly all of them have confirmed that it really is becoming too dangerous, and we probably made the right decision.

I really hope the World Cup will be a great success, and all fans traveling to Brazil remain safe. It's a shame that such a beautiful country with so many wonderful people and incredible culture has become so dangerous. If you do plan to travel to Brazil and seek advice, then I would be happy to help in any way that I can.

Using four buckets instead of two like that will improve your confidence in the results, but will also double the required sample / testing duration. You could just as easily use two buckets and wait twice as long to achieve the same effect.

It's from a University of Waikato researcher so they are likely using Weka to do all the "textbook" transformations before the final analysis.[1]

You could also go a long way towards reproducing the results with Python by installing NLTK and sci-kit learn. NLTK for tokenizing, stemming and similarity metrics.[2] Scikit-learn for tf-idf vectorization, k-means and even some of the datasets like 20news.[3] I use NLTK and scikit-learn for http://jkl.io

Weka has a partially free book and NLTK has a free book for you to look into as well. Scikit-learn has some of the best documentation and examples I've seen. But I agree that more papers should come with working implementations. The problem is that academics are judged on their publications and publications frequently build on previous ones, so the work for this paper might be the starting point for two more papers the author is planning and they don't want someone to just come along and publish those logical extensions off their hard work as they want the credit for themselves.

It will be hard to change this kind of academic culture until getting your dataset or code used and cited becomes more prestigious in metrics used for academic promotions.

My company just moved from a GChat-centric XMPP system to an all-in HipChat system. We don't have Google Apps because we have our own Exchange server, so not everyone gets a sane email address that can also be used as their GChat handle, so we've all relegated to using personal or work-specific personal Gmail accounts.

Just last week we onboarded a new developer and instead of having to spread her personal GChat address all over the company and make sure that everyone has authorized her to speak to them, and worked out the kinks for the few (like me) who run their own XMPP server that play russian roulette on whether Google is going to allow federation today... we just sent her a link to a URL which allowed her to create a user and immediately started downloading a client that once authenticated, connected her to the entire company.

Granted, we could have used our internal IRC server (we actually do have one set up), but the maintenance behind it really started to get to us. In order to use it we had to VPN in and connect, and backlog wasn't available to people that aren't technical enough to understand shell clients (like our project managers). When we did decide to open up the security permissions we had spam bots connecting 24/7 trying to get into our channel, which we then had to password protect, which ended up being another piece of tribal knowledge that "you just had to know".

Still, I continue to have Campfire (Flint.app), HipChat, Adium with XMPP for OTR, Google Hangouts for multi-person conferencing, Email, irssi and Twitter open all day. I wish I could consolodate them all into one, but I can't because they all have specific use cases. If HipChat was to allow an OTR plugin and multi-person video chats and screen sharing, that'd get rid of 4 of my communications^W daily distractions, but it wouldn't get rid of all of them because they serve different purposes.

At the very least, HipChat being free is a much better argument against using Lync now.
I didn't know the A series of paper sizes was built around the golden rectangle. Vignelli had some strong opinions on the US standard:

The international Standard paper sizes, called the A series, is based on a golden rectangle, the divine proportion. It is extremely handsome and practical as well. It is adopted by many countries around the world and is based on the German DIN metric Standards. The United States uses a basic letter size (8 1/2 x 11”) of ugly proportions, and results in complete chaos with an endless amount of paper sizes. It is a by-product of the culture of free enterprise, competition and waste. Just another example of themisinterpretations of freedom.

The A4 is the basic size for stationary. Two thirds of it is a square, a nice economical happenstance resulting from the golden rectangle. It is one of the reasons we tend to use as much as possible the DIN sizes: proportions are always leading to other nice proportions. This does not happen with the American basic size which leads to nothing. I counted 28 different standard sizes in USA!. The only reason we use it is because everybody in USA uses it, all stationary in USA is that size, so are manilla folders, files and office equipment! The repercussion of ugliness is endless.
I think the most memorable thing I learned in quantum mechanics is that quantum mechanical scattering is also exactly the fourier transform. Suddenly braggs law became much more sensible.
