> For sufficiently large black holes you can peacefully pass beyond the horizon (unless there's something else going on, like a firewall).

The article addresses this by pointing out that the "tidal forces" in question are only noticeable for smaller black holes (at which point "spaghettification" - which is, by the way, the formal technical term for this phenomenon - occurs); for larger ones, spaghettification forces are too small to even be felt.

The Wikipedia article on spaghettification [0] has more details. The mechanics are similar to those of a body's Roche limit (the point where the tidal forces of one body will disintegrate a satellite body held together only by its own gravity; i.e. the reason why the gas giants tend to have rings).

Granted, my own understanding of astrophysics isn't a whole lot better than an amateur level, either, but the article doesn't seem all that inconsistent with how people who do have expertise in astrophysics have described these sorts of things.

Open sourcing Android is arguably what made Android thrive and was amongst the smartest things that Google ever did, otherwise phone makers and careers would have continued preferring something they can have some control over, like Symbian. It's also arguably why Windows Phone is for the time being dead, with Android and iOS having a staggering 96% of the market, as nobody wants another tightly controlled platform/OS, as iOS itself fulfills that role pretty well and you can't beat Apple at its own game.

I don't know which definition you're referring to, but it's contrary to basic microeconomics. Open-source often fulfills one of these roles: (1) needed substitutes to prevent a dangerous competitor from completely controlling the market (e.g. Android vs iOS), (2) complementary products that increase the desirability of something else (e.g. Google Search), or (3) decreasing the cost of development (e.g. your favorite open-source programming language).

Also, the value of Gmail is not in its source-code and has nothing to do with it.
As I get older, both as a person and as a dev, I have come to the same realization as you: that a lot of the time I end up building things that I don't need "right now", but which I have to at least plan at the architectural level, lest be it a nightmare later on.

And then it hit me.. THIS is one of the areas of software development where I don't think reading more articles, techniques "mantras" etc will help. Only more practice will help. It ends up boiling down to how much experience as a developer you have, making those particular decisions.

I.e. It's a craft, not a science.

So as you grow up as a developer you suddenly find that you start to have certain "intuition" as to why I should actually plan for something that I don't need, vs actually ignoring something (a real "yagni"), but you just can't explain it in terms of generalizations. You end up saying.. "well.. it just feels like I Should do this, because I have been burned in the past when I ignored this intuition"

And I don't think I'm alone in this train of thought.

I'm not limiting the web. You're not limiting the web. The web has limits. Actual, hard physical limitations (along with confidentiality and privacy limits); limits that something running entirely locally, directly with your actual operating system simply suffers, and will always suffer, to a much, much, much lower degree. Your opinion (and my opinion) is meaningless when confronted with actual, physical reality.

Right tool for the job. That's all.

If I may extend your metaphor, the problem then becomes the scaffolding that lies between architecture and features. Another attempt at a rule of thumb is to ask the question: can I describe how this likely-but-not-yet-needed change would be addressed in the code? If there's no answer (or the answer is not satisfactory), the question becomes: what do I need to do to have a good answer to the previous question? And so on.
You're confusing a bunch of stuff together here. Agile and powerpoint aren't the same thing. And BDUF/waterfall isn't the same thing as writing specs nor is it the same thing as using reports/essays/documentation to drive discussion and design.

The problem with PowerPoint is that it incentivizes laziness and promotes pitch-culture to the detriment of quality in-depth discussion.

As I wrote in another post, how I would drive getting off of the pitch-train is through internal blogs, wikis, and possibly forums. The way things are today you tend to have 2 main tools in use: the pitch and then reactionary response (the email thread, bug trail, backlog, what-have-you). That's very limiting, myopic, and reactionary. It makes it difficult to have meaningful discussions at a meaty level of detail on things (designs, architectures, directions, etc.) Those things tend to happen in email threads which get unwieldy rather quickly.

You certainly don't need to have a report/document/memo/manifesto about every little thing. But when you need to have a discussion about, say, the direction of your whole product stack, major engineering changes, that sort of thing, it hurts when what should be a conversation at a level of an RFC is reduced to a pitch-deck that people then either thumbs up or thumbs down.

Microsoft can't really put a gun to developers' heads and force them to write software for Windows Phone. If developers don't want to write non-shit software, then the store will only have shit software. There's only so much a company can do. iOS and Android app support is coming in Windows Mobile 10 (http://www.theverge.com/2015/4/29/8511439/microsoft-windows-...) with minimal changes necessary to get the apps working.

> And from the looks of it, Microsoft's Edge only supports extensions installed from this same store filled with shit, it won't be open-source and it won't be cross platform.

Wut? It supports Chrome and Firefox extensions (http://www.digitaltrends.com/computing/microsofts-new-browse...) and like Windows and Windows Phone itself, sideloading will probably be supported.

If you go bash a product, at least make sure your bashing is accurate.
But even if they can be predicted, the benefit of doing them now is difficult or impossible to quantify. But the cost is unambiguous.
> If I remember my old problem set correctly, a black hole big enough for you to live your life in would be truly huge. IIRC the supermassive black hole at the center of the Milky Way would give you about 0.1 ms before you hit the singularity.

Would that be from the point-of-view of the one crossing the event horizon or from the point-of-view of the observer? If that 0.1ms is from the POV of the latter, then - due to relativistic time dilation - that could easily add up to one or more lifetimes for the event-horizon-crosser, no?

You're increasing the cost a lot there because the wheels need to be on bearings because you've going to have to hold the tube with some amount of preload. You can't just let it rest on the wheels, the wheels have to be pressed onto the tube at all times because the vehicle is moving very fast and any kind of minute deviation up or down will result in substantial forces between the tube and the vehicle which have to be transmitted through the wheels and into the foundation and eventually into the ground.

So now you have wheels, bearings, preload springs, hinges, travel arms, etc. Instead of a big piece of plate that is welded to the tube and bolted to the foundation you're talking about a big apparatus with moving parts and precision bearings. The plate and welding might cost $500 per. The other might cost $20k apiece. A person can buy a lot of rebar and concrete and forms and whatnot for $20k.
And at that point, they're competing not against automation, but the very human process of "Wouldn't those two make a cute couple?"

I like setting up my friends. Lots of people do. I've had some success at it, too (a couple of marriages, even). And I suspect, although I have no evidence, that friend-driven setups and blind dates are more likely to succeed than dating sites are.

fwiw, Grindr got around that particular problem by focusing on gay men. But that's a large niche, really.

Beyond the problem of men drowning women in messages, there's a question of the quality of those messages. The crap I see my female friends get online from dating sites is appalling. So many men have no idea how to approach women and make themselves appear attractive - and many of them have no idea just how much competition there is. Meanwhile, women have to plow through dozens of dick pics, hoping to maybe find one guy worth talking to. Their odds aren't any better, but for different reasons. Sigh.

I'm a web developer with a side project. I don't have the time/energy/knowledge/bandwidth to implement native apps for IOS and android. But I CAN make it work well enough in a mobile browser.

And lets not forget: developing for android is hard. You have a variety of models, with varying versions of android, running on different carriers; i've read some horror stories, and no thanks.

I'm quite quite happy developing for the web and keeping it on the web. I don't have to answer to any gate keeper or ask for permission for a new release. I don't have to share 30% of my profits, or be careful about implementing native functionality.

They just need a browser that can render HTML/JS/CSS. That browser will only get more optimized over the years, the network will only get faster, and the technologies to optimize the web for mobile will only increase.

I say more web, not less.
You're right, I glossed over that the article does address that point. So I retract that criticism.

I'm honestly at this point just exceedingly skeptical of mostly everything I read about theoretical physics unless it's coming directly from an expert.
You can e-file without an IRS-issued e-file PIN. I know of at least one tax filing software program that uses only your previous year's AGI to verify your identity to the IRS.

So having an e-file PIN, or even using an e-file PIN to e-file, does not imply that your tax return can't be e-filed by someone else who only has your previous year's AGI.
They learned from history. How many people do you know refuse to go see a 3D movie? Mostly because they went to an older-generation 3D movie and got motion-sickness or headaches?

> You were saying that YouTube is a slower and clunkier version of a 2000 native app.

You said: "Nothing in 2000 had a remotely similar feature set."

Not that Winamp 3 (released in 2002) was a svelte piece of software[0], but it could do realtime pitch/speed shifting and stream audio and video from the Internet. With a sufficiently fast connection, three seconds from link click to video stream start would be quite doable.

Streaming and decoding audio and video isn't anything new. The two new things that The Web brings us are "zero-install" and a the benefits of the large amount of sandboxing work that's been put into the major browsers.

[0] WA3 was slow because of the UI code, not because of the media stream and decode code. :)

I think you had it right first time. Much like you can define an interface without a concrete implementation, or a unit test without working code.

One rather hypothetical approach to the problem is separation of concerns - make pricing composable - starting with storm risks, and supporting other unknown, future risks. The obvious follow-on I see too often is to use some type of dependency injection, which is almost always (my experience - YMMV) a bad move - pricing risk components probably don't change often enough to warrant the configuration nightmare that ensues. Just recompile, and redeploy. Or use reflection to load available pricing modules, assuming the perf hit is acceptable.

You may not need to know the intricacies of pirate risk when delivering storm risk, but you do know that you'll be dealing with another risk after delivering storm risk. So plan for it.
Look at it this way... older founders may be less likely to create a unicorn, but they're more likely to create a business.
It's not complicated to understand if you already understand the prerequisite concept of individuality - that each person acts somewhat independently of everyone else in the world.

You have to understand individuality and apply it broadly. If you don't, then it's cognitively easier to lump people into groups that you don't have to care about, and can even grow to hate.

I think upvoting means promoting discussion, not necessarily liking the article linked.
Not really. Sometimes you know the cost right now will be less than a few hours. The future cost of the same changes will be at least that, with a very high liklihood (sometimes, a near certainty) of being 2-10x that.

Are you really arguing that this rule of thumb leads to optimal decisions 100% of the time?

Because that is clearly untrue. If you want to make the argument that allowing exceptions to the rule opens up a pandora's box that is ultimately worse than just always following the rule blindly, okay. I think I'd still disagree, but it's at least a defensible argument.

Yeah, it was a tongue-in-cheek response to "What exactly is the issue with wealth?".

I don't think there's anything wrong with making some money, but the magnitude of the wealth gap is clearly a serious problem (and evidence against the idea that wealth trickles down in some useful way).
The first line of this article reads: "It seems like Silicon Valley and Bay Area residents are finally getting fed up with rising home prices and crowded cities."

I'd say that's only half right. I don't think the people leaving SF for Seattle dislike crowded cities, the urban aspects of Seattle are part of the appeal. I'd say that it's almost 100% driven by housing costs.

Interestingly, the problem of high housing costs isn't just that it's hard to afford a house, there's something more frantic about San Francisco now. I grew up in SF in the 70s and 80s, and while I know Seattle (and pacific northwesterners in general) often resist the comparison to SF, I gotta tell you, I felt a vibe in Ballard and Fremont that had been missing for a very long time.

Will it last? Well, SF is the epicenter of tech, whereas Seattle is squarely located in the the first round of shock waves. I'd expect the effect on Fremont and Ballard to be a bit more muted than Noe or Bernal or the Mission, but yeah, they'll feel it up there.

To be fair, I'm pretty skeptical of stuff about black holes even when they do come from experts, since there's so much contradiction between general relativity and quantum mechanics in this particular context, and experts more well-versed in one field over the other will try to use that field's explanations over the other's.

Black holes are fuckin' weird.

That is irrelevant. I prefer to not have ads and Google is generally kind of to comply and suggest developers respect ad-blockers as well, even though the vast majority of Google's revenue comes from ads. To suggest going native to provide revenue over UX only benefits the provider, not the user.

The core problem is that PowerPoint is a tool that changes user behavior. Without PP a person sees their task as "how do I communicate my message to these people", with PP it's "how do I finish my slide deck". There are people who use PP to the end of much more effective communication, but those people are unicorns.

Almost universally, my experience with people is they only want to finish slides and spend an inordinate amount of time worrying about fonts and backgrounds and arrangements. When it comes time to present it's the usual awkward slide-reading and the slides only serve to distract the viewers from the messenger.

"Send me the deck" ends up being fairly useless as well because not enough context or content is actually in the slides. Sometimes you get a few bits of hyperlink gold or some single valuable piece of data.

In the end, I think PowerPoint is a powerful tool for effective communication that shouldn't be used in most circumstances (because in that "most" it makes communication worse). I appreciate the hard work and difficulty you must go through trying to design a tool to effect human behavior to promote good communications.
Agreed. Ads are a significant liability for both User experience and security.
