Because apparently we've run out of hard problems to solve in computing (as demonstrated by the amount of useless stuff we create) and need to think of the next UX trend that will give our users 0.0001% more satisfaction and increase productivity by 0.000009%.

Whether or not you are a fan of disappearing/reappearing headers, this is clearly a well-thought-out bit of code that will be useful to someone. The docs also appear clear and concise.

I like that it is not a jQuery plugin by default, but does provide the option. Even better (for me) is an Angular directive ready for immediate integration.

Well done and keep up the good work!

He did provide the design behind "these gotchas." It is at 43:40

As for the specific examples which he brings up, those also get the specific goal stated as to why C++ has that strange condition.

I don't mind paying a reasonable price for something that works very well and that I use every day. I used to use VirtualBox and after switching it is night-and-day difference.
I use bitlbee with hipchat so I can connect from Emacs. It's a bit awkward to set up, but it's a lot better than the official client since it works inside tmux+mosh.

Ha, no you crunch the numbers, you get the insights. Google does so whether you opt-in or not.

Something I'd like to do (someone else asked for an e.g.) is look back at programming language searches, as they'll nearly always have the lang in the query. I'd be able to see when I started learning e.g. python and had to google everything, when I picked up other languages, how those searches decreased (or increased) as I learned more. Lots of interesting stuff.
With IRC, you need a bouncer (e.g. znc) to get the functionality of seeing history without having the client open (and technically the bouncer is just the open client).
XChat was previously my client of choice, although I don't have much of a need for IRC on a daily basis anymore. Specifically, HipChat's integration with KDE's system tray and general look and feel is much more polished, IMO.

“The extent of consumer profiling today means that data brokers often know as much – or even more – about us than our family and friends, including our online and in-store purchases, our political and religious affiliations, our income and socioeconomic status, and more,”

And this is where the NSA/FBI will go to collect data in the future. If, miracle of miracles, we manage to get the government out of our daily lives, they'll just write NSLs to these guys and in one swoop pick up tons of information from dozens of sources -- including data about people we associate with, since no warrant will be required.

These guys were doing "interesting" things when I last looked five years ago. Who knows how bad it's gotten since then.

ADD: I've thought this thing through several times, and the only way forward I see is either outlawing any collection and aggregation of private data outside of that directly needed to provide service, not ads -- or making all information collected from any source publicly available to all. I don't see the middle ground. (Sadly)
I recall reading somewhere that the leading data point predicting car accidents was the driver's credit report, but this was decided to be private information in that case so car insurance companies were forbidden from using it. Where do you draw the line for this sort of information? It seems that PII (or Personally Qualifying Information in this case) is quite easy to find if there is someone trying hard enough to find it.

My company uses HipChat, and my group has been liking the video & audio features. My company also uses gmail & the google suite and traditionally it's always been a pain when trying to do a hangout chat w/ someone who hasn't done it before. Need to download some plugin, install something, blah blah. Not to mention that there are about 58.3 different ways of initiating a video chat w/ someone via google.

Since they've added the video chatting, we've been loving it. There's a single button to click, it Just Works, etc.
Some of the decisions can not be actually made based on facts, such as decisions about future performance of some person (there are no facts that can guarantee it) or future effect of certain policy (the facts may be lacking or subjective and depend on interpretation). So, unfortunately, in many aspects in the politics "decisions based on facts only" are just not possible.

"the government will let you do that, up to 5 kids in some places."

This is not true, actually if you are Han people, no matter where you move to (within China), you still can only have one child unless you married to "ethnic minority" who no need to follow "one child policy".
This was actually sent round a couple of weeks ago where I work by one of our executives (I work at a place that has Statistics in its name).

I didn't mention it then, because I didn't want to be a debbie downer and hurt everyone's "rah rah statistics yay!" feeling. Or send something round that contradicts an executive :P But the paper seemed dodgy as hell to me.

This wasn't solved with Statistics. Nor was it solved by Bayesian statistics. It was solved when people did lots of searching, failed to find anything for a while despite searching where the plane was, and then they eventually found the plane near its last known location despite having already searched there.

If anything, the paper was just an application of the texas sharpshooter fallacy. I believe the authors made several models, and then included the one in the paper that showed the result they wanted.

See paper: http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.370...

Indeed, see the graphical representation of the probability distribution in the paper, you'll notice that the plane was found in a section of the probability distribution that had already been searched earlier: an area that should now have a lower probability than the opposite half of the probability distribution if we're using semi-reasonable bayesian techniques. Indeed, this is what we see in figure seven.

In figure 8, we see their new probability distribution under the assumption that the beacons did not work at all, where they try to say their method pinpointed where the plane was. But since this was not known at the time, and figure 7 is the far more reasonable bayesian model given previous searches in the area (because figure 8 assumes a 100% probability of both beacons failing, something practically no bayesian would do), i posit that they either made that model after the fact, or they indeed had several models fitting several different scenarios, and after the plane was found, they chose the one that best fit the data post-facto. Odds are, if the plane was found, it would fit one of their scenarios, and they would then write a paper saying how their model was such a success. Figure 7 is the far more reasonable bayesian distribution, and it actually tells you to now search in the wrong area.

If they followed bayesian methods, there is in fact a bottom half of their distribution that should of been searched next (where the plane wasn't), and they in fact found the plane in an area that had already been passively searched: an area that should have downplayed by bayesian probabilities for future searches because of the unlikely-ness of this area being searched and yet still finding nothing.

I actually like Bayes, A LOT, but this is not a good example, except perhaps of the precept: if you want to find a lost plane, its probably a good idea to start looking near where it was last located.
Nice article, but I really love the photo of the monkey!
To some extent, we always have to extrapolate from the short-term into the long term, but the point is to remember that we are doing so, and to reduce our confidence accordingly.

It's no surprise you're demotivated, you've been creating empty work for yourself like an invoicing system and a support system when you don't have any customers. This kind of work does not make your company better and it's so premature it's not even useful.

Launch the paid version and focus on getting customers. Then your work will have meaning and impact and your company will be able to move forward.
I totally agree with new account with new account with a different email address problem. Apart from that one big issue I've is privacy. As such admins can't see private messages, however since you will be registered to HipChat with your organizational email the admins can just reset your email password followed by Hipchat and eventually see all your private messages. I've seen this happen.
It's not as complex as you make it sound. The parser should pass along any non-terminal characters without issue.

The rest of the edge cases (ex newlines in data) can be handled by using a proper DFM (Deterministic Finite State Machine). None of that String.split('\n').split(',') garbage.

If you're processing text as binary without using a string reader that can differentiate between UTF-8 and ASCII then you're doing it wrong.

With that said, I agree completely that people should use an established library. Code that has been viewed, used, broken by thousands of users is infinitely better than any home grown variant.

Quite fitting...

“What you see is three groups, in three different countries, reporting these multiple Efimov states all within about one month,” said Chin, who led one of the groups. “It’s totally amazing.”
I call [citation needed] on your EU demographics. The EU has not been "stuck in a massive population drop rate": the EU population actually grew by 3.7% between 2002 and 2001, with only 6.3% born outside of the EU. And Eurostat forecasts the population to grow very modestly between now and 2060. (Source: http://en.wikipedia.org/wiki/Demographics_of_the_European_Un...) Of course, those predictions don't mean all that much, since "demography is destiny" only in retrospect: growth trends can and do change. (E.g. the French birth rate has gone up in recent years.)

To be honest, I think you may have read too much Mark Steyn. There is little cause for demographic apocalyptics, including the tired "Muslims are going to revolt/take over" kind. In fact, a flat or slightly declining population is probably a blessing (e.g. from an environmental perspective).

I think there's more to demographic destiny than constantly growing populations. For example, the 'demographic dividend' is a double-edged sword, resulting in economic growth if enough jobs can be created or the potential for massive unrest otherwise. (This is one problem which India and much of Africa is grappling with.)

At the same time productivity per worker has gone up dramatically in many industrialized and industrializing countries, even as (and in some cases because) of automation becoming more and more widely adopted. On one hand we're having discussions about how to handle large numbers of workers rendered redundant because of automation destroying jobs (e.g. guaranteed minimum income); on the other hand we're predicting that an economy won't have enough workers to fill all the jobs that will be created because of demographic trends. These things are contradictory.

I used SimpleHTTPServer for a while, but I found it a bit sluggish at times. I replaced SimpleHTTPServer with http-server, and I've been very pleased with its performance:

> Interesting how they are deprecating one tech (NPAPI) in the name of open web

The only reference to the open web is

> Most use cases that previously required NPAPI are now supported by JavaScript-based open web technologies

while the reasoning given for deprecation is explicitly "security, speed, and stability", which is certainly true. NPAPI is bad, bad business, and wouldn't fly for a second today if it weren't grandfathered into browsers.

It's a shame that there's still the NaCl fallback, but I would give good odds this will end up a positive for everyone as a forcing function, since the remaining plugins will look to JS-based solutions first since they'll continue working in all browsers.

(now, unfortunately some of those will be turning to EME, but that's a different series of poor decisions)
Yes, unfortunately the data is most solid on the successes because their valuations are public information whereas the figures are more shakey with the smaller companies, and creating an estimate that subtracts the outliers is pretty flimsy.

Our best guess is that 78% of the earnings are in the top three companies gives a general idea of the kind of adjustment you'd have to make.

There was a BBC program a couple of years back on secret services MI5/6 and they contrasted how we do it in the UK and The USA.

One example was an IRA arms dealer caught bang to rights actually at the buying point he got off on a tiny technicality - whereas the amount of stuff that the FBI where allowed to do was interesting and slightly disturbing.

It might have been on PBS or BBC America at some point

I think you'd have trouble arguing that US involvement in WWII wasn't dictated by government regulation (Lend-Lease and the Japanese Oil Embargo), but the point was more that it's not an irreversible trend.

Presumably if there's some optimal wealth inequality based on our technology level/social structure/ect. we'll naturally trend towards it on a long enough timeline.
Biggest issue I've had with excel and spreadsheets in general has been "put this on the web". People spend hours/days/weeks building a spreadsheet tool that does all their calculations, then say "put this on the web" to me, and I can't do it. Not in their budget. To them, it should just be some sort of magic, but... I don't know of tools to just 'put' something like that on the web. They want people to be able to interact with it, but 'not download it'. They won't use Google spreadsheets or any office365 online stuff.

Maybe there are some tools that can take an xlsx file and make it secure, interactive and loggable and are also free (or nearly so?) Am I missing something?
They're not replacements for those tools. They're new tools that work with a specific tabular data format.
This is interesting, I think you're saying that this advice could be for utilitarian good, ignoring the individual.

From a purely utilitarian perspective, maybe the startup compensation curve is best for philanthropy.

Hypothesis: 1,000 people making $100,000 will give significantly less in aggregate than 1 person with $100,000,000. Therefore, if more people go into a corporate ladder job for the $100k, there will be less total giving.

We switched to Flowdock and never looked back. The SNR advantages of the integrated conversation threads and "email-like" inbox model are amazing. I never knew what I was missing with IRC/hipchat.
For the DIY crowd, implementing this on your own is a straightforward (and fun) exercise.

I used the Javascript Bayesian Bandit library found here:

https://github.com/omphalos/bayesian-bandit.js/blob/master/b...

I then used it to create a job that runs every 5 minutes on parse.com that updates an 'order' field based on the 5 minute sample.

Then, from the client side, I simply do a query sorted by the 'order' field and I get the top variant for that 5 minute interval. Works like a charm!

>First, 17 countries? WTF? Why is he deliberately limiting the sample to predominantly caucasian countries? The US certainly has its faults, but it comes in at #3 on the UN's Human Development Index. Why not show data from the top 20 nations on that list? Is there really a problem with finding "religiosity" data for Japan, South Korea, Hong Kong, Israel, and Singapore? (Ireland comes in at #7 in the latest ranking while the UK is #27, behind Slovenia, Spain, and Italy.) It appears he's citing a 2009 Gregory Paul paper that argues the US is a more secular nation than a 2008 Baylor study indicated, which has me scratching my head.

The first world is an outdated term, originally used to describe the countries aligned with the US during the Cold War. I agree that it would have been better to use the top 20 nations on the UN's HDI, but given the term the choice of countries was correct.

>Alas, immediately after stating the US is the worst of the lot in measurements including life expectancy in some manner because of its popular religiosity, he makes the case that religiosity is a social survival trait and shows a chart indicating that religious communes last longer than secular ones. At which point I found myself wondering exactly what point he was trying to make. Atheism is the way forward even though religious nations are more likely to survive? Which is a pity, because I quite agree with his larger points on government intrusions on our privacy.

A trait that causes cells to die at some predetermined time can benefit the organism as a whole, for example by preventing cancer. Similarly, Peter Watts seems to be arguing that although religiosity causes life expectancy and a whole slew of other important metrics to plummet, it strengthens the collective whole by building group cohesiveness. Put crudely, fanatics make useful cannon fodder.

I developed a set of utilities for Excel (http://www.breezetree.com/spreadspeed/), and I started adding some auditing features to it. After spending a few weeks on the auditing tools, I decided that I should do a little market research before investing more time on auditing features. Well, I'm glad I did because I found out that the market is saturated with spreadsheet auditing tools. Most are simple and inexpensive (like mine), but there are some fairly sophisticated tools out there. So my takeaway from this is not that there aren't sufficient auditing tools, but that the market needs a non-programmer, user-friendly way to build robust yet malleable models.
