It's a chicken-and-egg problem. New things are uncertain, uncertain things are risky, risky things aren't funded, thus new things stay new.

"This new technology is expensive because it's new!" is a tautology that gets us nowhere in terms of progress at a social level.
In a class I took in college, we had to give a final presentation to go along with a paper we wrote. The presentations were to be about 30 minutes (not too hard to come up with content, as my paper ended up being 50 pages). With the paper, this was essentially our entire grade for the class.

I decided to do it without PowerPoint. I was the only one.

Instead of relying on slides, I looked people in the eye and gave a presentation from memory, with a set of index cards as backup. I told stories and tried to make it relatable. Now, I've gotten better at these kinds of things over the course of my career, but even in college I was pretty confident in my ability to give these kinds of presentations. (I even took an acting class just to refine my public speaking skills.) Anyway, after I was finished I felt good about how I did.

I got a C-. Literally the only feedback the professor gave me was that I should have had a PowerPoint presentation "to give people something to look at while I talked".

Except it's difficult/impossible to edit a PDF file. How would you handle the use-case where multiple authors are collaborating on a single powerpoint file?

Plus, PDFs can be generated from Powerpoint.

The real key would be for some App to codify good presentation rules and target OOXML output. I'm not talking Keynote - It needs to be more focused and opinionated, and make that part easier.

Is that even possible? Would Microsoft permit it to exist?
Thanks for your feedback - getting the UI right is one of the big challenges for us given the complexity of the system. We've been experimenting internally with different approaches, one of them being a per-user preference "raw" mode that works as you described.
That formula is more correct, but only assuming you don't replace any churned customers – or at least, replace them all at once at the end of the year, which seems like a pretty unreasonable assumption to me.

If you replace customers every month then the number leaving per month is constant, so you end up churning 0.05×12 = 60% of your userbase per year.

Edit: The 12x model is also pretty coarse, but you can take the limit of continuous replacement, and you end up churning

-12log(1-x) = 0.616

× your customer base per year.
You're assuming no replacement.

I think the calculation runs like this as per[0]
5% => 1/.05 = 20 months average lifespan = 1.67 years => 1/1.67 = 60% yearly churn.

For as much as history portrays Napoleon as a dictator (which he was), it neglects that most of his adversaries were ALSO dictators who did equally horrible things.

In Napoleon's mind, he wasn't as much conquering Europe as liberating it from the clutches of nobility. Napoleon viewed himself as a better kind of dictator than the other European monarchs: one who rose to power through his own merit and who selected men for tasks based on their abilities, not their bloodlines. This narrative was decidedly less popular outside of France -- which had essentially executed all of its nobility in the preceding decades, so there was nobody left to disagree. But it really was a war of ideals over who should rule: an arbitrary (and increasingly inbred) line of inherited nobility, or the best man for the job?

If Napoleon had won at Waterloo, Europe would have saved itself a century of war. But the USA would also not exist in its current form -- much of the reason for the rise of American dominance in the 20th century was because Europe was rebuilt after WWII by the American war machine cranking out large quantities of steel and industrial machinery.

And who knows how the 20th century would have turned out without the US as a global superpower. Maybe without war and famine in 19th century Europe, there's never a migration and the central US remains as uninhabited as Siberia. It's fun to think of the "what if?" questions,

Yeah. No wonder people figure out that it is not the right career path for them when people will jump on them for admitting any kind of "programmer weakness"[1], or for not being perfectly passionate about programming all the time, or for not thanking their boss for having the privilege of getting their generous pay-check and almost salivating at getting more overtime to work on the companies' interesting problems.

Sometime the work itself might not be as bad as the people you have to do it with.

PowerPoint doesn't kill presentations - people do.
In my experience, HTML-style layout is just horrible for app UI. It's really much better suited for text. On iOS, you can either use autolayout (constraint-based layout) or alternatively perform layout manually, in code, for that purpose.
I spend ages whenever I have to do a powerpoint (or libreoffice) presentation.

Drawing a box with text in it will take me maybe ten time longer in PP compared to a transparency. Admittedly the lines will be straight, and the text more readable (assuming I choose a reasonable font size), but its so time consuming in comparison.

The data trap: affordable smartphones, expensive data – Jana Blog
You're right. My whipping boy analogy is a bit leaky, especially if one tries to project it the specifics of this case.

Here's my concern: Employees work under incentive structures that are established by their employers and are supervised by the executive teams. When breaking the law becomes "commonplace" in a system, the people who are responsible for governing that system must be held accountable if the negligence verges on criminal.

As a society, it's critical we have a reasonable legal framework that strongly encourages executives to make sure they have effective internal controls to detect and discourage criminal activity from employees. If we don't have that, then we're effectively giving executives whipping boys who can be used to shield them from the bulk of liability.

That's an interesting one. This is actually contrary to most conventional wisdom regarding such projects, rail for instance does not have a reduced cost / mile if the distances get longer. (Airtravel does, however).
Please don't make acerbic swipes at other users. If there's a general point you want to make about dating and social class, that's easy enough to formulate without being snarky or personal.

> At the same time (possibly it's the same effect) the definition of geek has softened. It's much less pejorative, much less sci-fi and math-club, than it used to be. It's almost trendy. It's certainly been co-opted by marketing and consumer interests.

Nerdy shows are more likely to reference the sorts of things you'd read about on Wikipedia, hence the frequency with which you might see shows like Futurama show up in the popular culture sections of Wikipedia articles. And, of course, Wikipedians are likely to be nerds who catch those references and rush to update the appropriate article.
Because now we have infinitely many imaginary hypotheses, and we can't resolve their differences since we have not enough facts, and ones that are ornate and humane tend to capture most attention.

Also, the lower weight makes the phone more resilient to drops. Anecdotal evidence: I've never seen a cracked iPhone 5, but cracked iPhone 4's were common.

Less volume means less mass, which means less kinetic energy that must be absorbed by the frame when dropped on the floor.

var tokenize = function(input) {

Code like this makes me a little upset. It'll completely break on simple cases: `(print "To close the REPL, type (quit).")` being an obvious example.

I get that it's a toy example, but all too often it slides into tricking people that hard* problems are trivial.

The criticisms made against dating startups could be levied for many other market segments as well. I imagine that if investors are shying away from dating startups, it's for no other reason than Dating Startups are no longer in vogue (because dating is complex), and the heard tends to stick together. Dating is a common problem, and investors have gotten "dating app" fatigue.

Here are some counter points.

> I’ve heard [Churn] numbers as high as 20-30% monthly

Making an argument based on hear-say.

> Dating is niche and has a shelf-life

So is the market segment for weddings, and newborns. Underserved niche markets are ripe for "disruption" which follows with it--investment.

> Dating products have historically depended on paid acquisition channels to build their customer base,

Source?

> City-by-city expansion sucks

It's an extra challenge, but ubers, and airbnb's and many other marketplace as a service have figured it out.

> Demographic mismatch with older, married investors

While there are investors whose methodology precludes them from investing in markets that have not bearing on them, it's probably safe to assume at one point in their life, they had to date.

Dating has always been a game of breadth first search and sampling with rapid feedback. The "promenade" (a town or two would meet up, single boys circled clockwise around a circle of anti-clockwise girls) was commonplace in eighteenth and nineteenth century Europe.

In the end though, most business and consumer interactions at least begin with something very similar to dating. So solutions found in "proper" dating sites ought to be translatable to sales and marketing apps

Even advertising is a weird form of one sided dating, with the most promiscuous and least picky self selecting for paid exposure to man y many potential new partners.
Short answer: Yes

Longer answer: Why would you assume that your development preferences (yes, preferences! not needs!) are so important as to justify cutting the legs out from underneath a huge swath of problems that other people on the planet are working on?

It's not by any means the only challenge out there, but it's a particularly good one. It's multi-dimensional, drawing upon virtually every human talent imaginable: technical, social, aesthetic, scientific. It's long-term, complex and multi-faceted, and incredibly tangible. Anyone can look up in the sky and find Mars. In human mythology heaven is almost always "up"; it seems to resonate with both ancient and modern mythology. I can't think of many other challenges that are as rich as this one.

Kubuntu Project Lead Asked to Step Down by Ubuntu Community Council

We run a reddit alternative/competitor at http://snapzu.com and we've been mentioned a few times recently in reddit threads mentioning the whole Ellen Pao censoring debacle.

As you can imagine, it's actually quite tough getting a community off the ground, but we managed to get just under 10,000 members in around 2 years, and it's just speeding up as demand goes up and as word spreads of an alternative to go to.

The problem reddit is having is that they grew up (over 10 years) as a free-speech platform, and just recently changed their policy that promotes "safe places", essentially censoring any free-speech that they consider "harassment". This is literally a licence to be able to mute (shadow ban) anyone that steps up against them. People are getting really fed up. It's actually quite interesting to see how all of this unfolds.
The article seems curiously devoid of explanation as to what caused the burnout. As a result there is no reasoning in it really as to how to avoid burnout. ( besides "take a break when you need it" )

It seems to imply that burnout is a failing of the employee not of the employer. I disagree with this notion entirely, as I think management has a duty to care for and protect their employees from burnout. That is why there is always a chain of responsibility, so that this can occur at all places on the chain.

A properly functioning corporation will help their employees avoid burnout and not make demands of them that inevitably cause it.

That would have never happened without British involvement, since they controlled the sea. Furthermore, as the article pointed out, Napoleon and America shared similar ideals. Finally, fighting a war in your homeland is infinitely easier than the supply lines Napoleon would have had to maintain to fight in America. It would have been absurdly expensive and would have opened France up to attack from its unfriendly neighbors. In conclusion, I do not think there is a likely scenario that envisions an America under Napoleonic rule.
I agree with this very strongly. Be very careful what you post about yourself online that is associated with your easily searchable name that you put on job applications. Burnout may be a real problem, but stating you think burnout is somewhat normal and that you will occasionally need time off to recover ( like op seems to state in article ) is not going to win you any high stakes high reward positions.

Agreed also it important to have continuous work listings on your resume. "I was laid off and it took a bit of time to find a good position" is usually the easiest excuse for <3 months of time off.
