"All good engineering works on the principle of defence in depth."

That line is as much a sound-bite at this point as anything you'll hear on cable television. Yes, good engineering has many levels of fall-backs and redundancies. But when you've reached the point that you've evacuated the last fifty people from your site because it's no longer safe for them to be there, then you've exhausted your defenses. There's no more depth.

Let's stop whistling past the graveyard: a meltdown is, in fact, a really big deal. Maybe the "wide concrete tray" will capture the waste. Maybe it won't. But in the meantime, you're hoping that there's not a secondary fire from the heat, or a steam explosion, or some other kind of explosion that flings radioactive particulate for miles around. You're hoping that the fuel won't melt, form a critical mass in the bottom of the reactor, and re-initiate a reaction that's hard to stop. You're hoping that the containment doesn't breach, and that vast quantities of radioactive waste aren't exposed to the elements before the whole system calms down again. You're hoping that the whole system calms down again.

The point is: they've lost control. The 'engineering' that they're doing right now is desperate and hacky, and they're very nearly out of options. It might be comforting to pretend that this whole thing is scripted out on some intricate Japanese checklist somewhere, but that's really nothing more than a fantasy. I certainly hope that things aren't as bad as they sound, but this isn't just a matter of bad PR by some pessimistic, nuclear-energy skeptics. These guys are actually in trouble.

This article doesn't really cover new ground. Software engineers have known about this for many years and Microsoft's OLE and Apple's ill-fated OpenDoc[1] were developed to address some of these issues.

Welcome to Australia where there have always been caps - partially because we download so much content from the USA that someone has to pay for the fibre under the ocean to carry it all to us. Caps do change consumer behaviour a lot, but that said the caps are getting generous enough these days to not be too restrictive. If you shop around you can get a Terabyte a month for a reasonable price and can only use that amount by streaming video content. Part of what aussie ISP's do now is offer steaming content free if you are their customer. iiNet does this with its Fetch-TV service, and also has unmetered access to iTunes, ABC iView and gaming content.
I didn't expect you to do that and was joking (hence the wink) but it would be amazing to see it AT work. If you had added the Trie in this post, it would have probably been over the average human threshold of patience and understanding.

It's funny you mention that. Just yesterday I made a graph of how many accounts were created each day since the beginning of reddit. It's very clear which day Paul mentioned reddit in his essay, because there was a 3x jump in signups that day. More importantly, it never receded from that level. I like to think this is because people kept finding his essays.

Vim: Walking Without Crutches
What if your college provided email accounts that only forwarded mail to a student-chosen account? Then students could access their mail from any accessible internet or desktop client they choose, and they could get discounts requiring .edu accounts. It would require students to sign up for email on their own, but I wouldn’t think that to be a problem – it’s like requiring students to buy their own textbooks.

When 15th Is Better Than 8th: The Math Shows the Bracket Is Backward
Most of the time when someone talks about "easy recursive-descent parser" it is not even strictly speaking a real recursive descent parser. It is usually some kind of top-down parser with horrendous tricks thrown in.

Is it easier to write parsers like that? Definitely, I did my fair share of this exercise too. Is it a good thing to do? Not if you want a fast, reliable and maintainable parser. Yes, using LALR(0) (or LALR(k) or whatever) parser generator requires much more effort and disciplined thinking but in exchange you get time and memory constraint guarantees, error reporting and (sometimes) error recovery for free and may be even the tool-chain for subsequent stages (AST, attributed grammars, IR).

So if I see a phrase "let it be a hack" in the text about parsing, there is a good chance that parsers written with this mindset run in exponential time.

I am not saying that "recursive-descent" or any other ad hoc approach is bad. Sometimes you do have to resort to various hacks. Even original C is not, strictly speaking, a context-free language: parser has to consult a symbol table to recognize identifier class to parse source code properly. C++ (which is a textbook example of how NOT to design programming languages) made things 100x worse. But, for obvious reasons, you still need to parse those languages. So, at some point gcc developers just rewrote C++ frontend from scratch using recursive descent techniques, because it is so much easier to intervene and introduce hacks in this framework than in the rules for LALR parser generator like yacc or bison.

TL;DR version of my response: use recursive descent if you have to, but using it for everything is just a demonstration of ignorance and may significantly hurt performance and maintainability.
We would still have to deal with the administrative tasks of all those thousands of forwarding accounts. The only thing that forwarding would save is storage space. And that's likely a minimal cost.

Though, since that kind of thing isn't what I deal with, I might ask the people who do what they think of that idea.
Like it or not, at many big companies, word docs and excel spreadsheets (and powerpoints...) get abused in incredible ways. You'll somehow end up distributing a training document in an excel spreadsheet, and then some not-so-tech-savy manager will come up with the brilliant idea of including VIDEOS in the training documents... and then it begins.

Simply put, Microsoft and Adobe will cram as much crap into their fileformats (pdfs...) as they think random middle managers in large corporations want (and sadly actually use...).

I've seen such things done. It hurts to get a word doc that's just full of embedded jpgs from a scan of a printed out pdf that was originally a website...

I agree. Instead of (or in addition to) creating a website like this on tumblr, you could showcase your design skills by creating a better designed and more visually appealing website. Works better to get you a new job than a simple footnote saying "I'm available for hire..."
This is not a good argument. You have no legal right to drive an automobile or to fly a plane, both are heavily regulated. The "if you have a job that requires X" argument is fundamentally weak, there is no intrinsically superior right to any activity due to it being job related or not (this is a good thing, I believe).

The problem of course is the extent of intrusion on daily lives.

The better legal approach is the 10th amendment route, or coming up with new legislation.
I find the quality of light to be a big factor for me. Sitting in front of a big window, or heading to a coffee shop and sitting right next to one of their big picture windows helps a lot.

Even if most of your friends are working, you can set up short lunch dates to catch up and get some people time.
It's the same kind of overdramatic reaction that TechCrunch is known for. The email even said that TechCrunch had no obligation to comply. Probably some guy called Moviefone and said, "I see you guys own TechCrunch now, can you ask them to change their story?" and the guy said, "Uh, I guess I can ask for you, but no promises...", and then wrote that email, and now TechCrunch, in typical fashion, is blowing something way out of proportion, which in turn generates more publicity for itself, AOL, The Source Code, and Moviefone anyway.

I don't see much to praise here. The intentions might have been good, but otherwise it's a waste of space and time for everyone that isn't getting publicity out of the deal.

For all the applicants on the fence my only response is that yo have nothing to lose. If you don't get picked then so be it but there have be a lot of successful start-ups that are not chosen to participate every year. If you are placing all of your chips on the YC to help you make it then I think it would behoove you to reassess your goals. start ups are about creating something that solves a problem, changes lives and to make okay products better. The initial start up should be about creating a stellar product more than it is about money. To those critics, yes money is a crucial aspect of business but start-up have the unique ability to bootstrap and work under financial constraints that most would never be possible. Creating a start up is as much about the business as it is the experience of starting that business. So go for it you have nothing to loose.
Have you spoken with others in the startup? Do they feel the same way? Have you told your boss this? You should, and either they hear you and try to learn from their mistakes, or they don't and you move on.
Because the only thing separating the vast majority of the mainstream media from tabloid journalism is mere perception and production value?

That is odd, if the time-stamp actually said that. I responded after reading that, and it took me a while, with interruptions in between.

So I guess that puts you one level above "casual spammer." How do you sleep at night?
I can pretty much confirm this is the case. I was told as much way back in 1996 at a job interview for the local part of (the what was then unnamed but now has probably changed its name again) Echelon network. (Run out of the GCSB in NZ).

That is, it was explained to me that while we don't 'spy' on our citizens we supply as part of the partnership the ability for each member country to basically circumvent those restrictions because the entity doing the surveillance is actually a foreign government (all be it an ally). Not exactly in those terms but I was left in no doubt that that was how it worked.

Of course if they told me that a job interview I imagine it was regarded as public knowledge.
I take exception here. The geometry of exposure is completely different. This is designed to deposit energy near the surface of your body. All of the numbers we have put together for cancer exposure risk are based on data concerning higher energy radiation that tends to pass through you and deposit energy throughout your body. This is why the skin -- which is cancer prone because it's continually replacing cells -- has lower multipliers for risk in those models.

The data we have -- the data used in the model used to conclude this stuff is safe -- is for the wrong geometry. Please, no "spherical cow" assumptions when it comes to my health. Zap a bunch of little furry creatures with the same equipment, then I'll feel safe.

It would be brilliant, but it isn't realistic at the moment. I don't think anyone would want to watch Firefly without Mal and Jayne, and those actors are both under contract (to Castle and Chuck, respectively).

c) Will do. Dumb Q: are these for people who're on platforms we don't support yet? Why would iPhone users want to leave their email addresses?

d) Will do, great idea!
Zillow.com Said to Hire Citigroup to Manage Its Initial Public Offering
Right. Most of the radiologicals that have been released with the steam have very short half lives so the radiation levels drop rapidly (relatively speaking).
My university taught LL and LR parsing as 'compilers'. But you actually don't need anything complicated. A lisp parser is very simple, and colorForth does away with parsing entirely.

Never the less, everyone pushes for yet more special case syntax in their compilers. But the more 'intelligent' parsers become, the less intelligible their own code becomes.

Personally, I don't think a useful 'composable grammer' language will materialize. But an alternative exists: simple syntax that let you define your own semantics.

Dilution is apart of the entrepreneurial game, I am not surprised that Westergren only has 3%, his value proposition for the first 2 years to investors was less than stellar. investors that put money into this type of startup require large amounts of equity because they need assurance that they will receive a return on their money that they pay forward
Japan seems to have very little crime, or at least, very little obvious crime. This may be rooted in their distant past. Here is a quote from "Sources of Japanese Tradition - From Earliest Times to 1600" which contains description of Japan by Chinese from around 297 CE:

There is no theft, and litigation is infrequent. In case of violations of the law, the light offender loses his wife and children by confiscation; as for the grave offender, the members of his household and also his kinsmen are exterminated.
Beautifully designed. It feels as if I am talking to a real person.
More so, modern Japan is not a pure entity, it is the product of Japan's prior history, the events of WWII, the American occupation, the reconstruction, and the close ties with America since. Without all of the latter Japan as a nation would be quite different today.
Debunking a viral blog post on the nuke threat
That's probably an expansion path being considered. There are plenty of series that have had big cult success after their cancellation. Firefly is one of them but there's also Arrested Development and, more recently, Better Off Ted for example. Letting others take the risk and capitalizing after proven market viability (basically picking up half of what Fox cancels) could be interesting.

Give a Rocket Scientist a Lift
Yes, but I would not think about it as code sharing. MSI (the installation technology used by Office and most Windows programs) supports the notion of "Shared Components," which allows applications to share common resources. A component is a discrete installation unit, and in the case of large products such as the Office suite, many components make up any one product (Word, Excel, etc.). Rather than sharing actual source code or bundling the same DLLs with each Office product, components are shared between the products. You can envision that rather than each product containing the same code used to generate tables, they all use the same piece of code when generating tables. There are a variety of advantages, of which perfect interop between pieces of software is by far the greatest.

The Open Source trials: hanging in the legal balance of copyright and copyleft
This is a really interesting move given that Netflix has traditionally tried to push people towards lesser known content. In fact, they don't make that much money on people using Netflix for blockbusters but are much better off with the recommendations. It's a bit odd that they would go for a big name celebrity for their first owned series. This may just be a way to get a foot in the door, and then buy lesser known series for a lot less and push new content in a way we've never seen before.
