Blackboard is so shit that sometimes you look at it and out loudly say "what the fuck is this shit and who thought it was a good idea?". I remember trying to upload a document, dragging the file to the upload button and the file opening in the browser. Whereas if they used the standard _HTML4_ file input type, you can drag files on top of them to select them without browsing to its location.

I cruise without Java and Flash so it must have been some sort of hacked together proprietary upload button which triggered a regular file dialog anyway (JavaScript was enabled, I think). And that's just the tip of the iceberg. If there's any space to disrupt it's e-learning, but that's probably more of a deal-cutting job with major institutions than having an objectively better (looking) product.

I can grant an application permission to access my data on Facebook. I can't let an application get info about my friends though, that's their information and they control access through their own Facebook account. Otherwise, any single one of your friends authorizing an application would result in that application getting all your data. Obviously Facebook needs to err on the side of caution here, but hopefully there will be some new more restricted APIs in the future.

Oh, and as an added bonus they block all competition from accessing their incredibly valuable social graph, securing their monopoly for the future.

From what I understand, many of his early marriages were a result of affairs with young "starlets" which resulted in pregnancy and subsequent marriage to avoid legal issues or further career damage. Those early marriages didn't last since they were only based on necessity but when he married O'Neill, they actually made a stable couple.

It's interesting to read about as it's the sort of thing you see in so many other stories about "stars" sleeping with groupies or other admirers, often below the modern age of consent. I've wondered before how much of that has to do with the stereotypical entertainer's lifestyle or what it says about arrested development in performing artists.

This was widely discussed when Groupon was hot:

http://techcrunch.com/2011/06/13/why-groupon-is-poised-for-c...

There were also substantial concerns that the whole thing was basically a fancy, web-scale pump and dump:

http://www.thestreet.com/story/11661220/1/is-groupon-a-scam-...

In my view, the whole "daily deals" thing that they started with was always unsustainable at scale. It's one of those things that works well in small doses, but as you scale it up the value declines. However, it was novel enough and generated enough volume that it took small business owners a while to collectively realize that Groupon promotions didn't help them in the long term.

I was a big fan of Kozmo (and its NYC competitor UrbanFetch) but it was an entirely different kind of experience shopping on an EGA monitor with a dialup connection and I understand why it wasn't as easy to make it work.
> He was playing quite a "role" when he was the first president to try to end, rather than contain, the Soviet Union, and then achieved that.

There is no concrete way in which his policies were more substantially more aimed at ending the USSR than containing it compared to prior administrations (in many ways, it was perfectly within the range of approaches taken by prior regimes; the most substantial differentiating element that people tend to point to was the big ramp up in defense spending -- which was a policy initiated by Carter at the end of his term.)

And his administration did not achieve ending the USSR, either.

To me, your problem does not sound like you need to switch genres. The problem sounds like product life cycle.

When I got married, as part of my pre-marital counseling I took a personality test. On one question I got a score of 2 (on a scale of 1-5), but I couldn't understand the question. The man giving me the test explained that in my world, it was product life cycle. 1 is initial conception, 2 is initial prototype, 3 is delivery, 4 is major enhancement, and 5 is maintenance. I prefer to be at prototype to delivery, and I can handle major enhancement because it's essentially like a mini-prototype-and-release. Initial conception I don't like, because everything is possible but nothing is decided, and maintenance is just boring.

It sounds like you may be in a similar situation. You may literally have a personality clash with the phase of the product life cycle that you find yourself in.
This is insane. It's a service that generates private keys for you and stores copies.

Yes, you can set up 3rd party access restrictions on your organization accounts and manage access for each organization independently.

This is a common misconception.

The way the EU's "common external power supply" standard was implemented allowed the manufacturers to pick the standard themselves.

Essentially the EU put a gun to manufacturer's heads, and said "pick a common standard together, or we will!" And they did. So the EU never picked micro-USB, the manufacturers did.

Additionally the original memorandum of understanding has since expired (2012) but it has been deemed a "success" as all major mobile phone manufacturers continue to utilise micro-USB.

So there's no specific reason why USB-C cannot become the new normal. And it seems manufacturers have actually become used to the status quo of having a common standard (except Apple of course).

I don't think you'd see the EU get involved if all of them together moved to USB-C (from micro-USB), they would only get involved if they started to developer proprietary ports again, or all had different incompatible ports/chargers.

Now they just need to do laptops...
Unfortunately STM uses a lot of external silicon IP (all MCU designers have to) from different firms that don't really work well together or are straight up inferior as you mentioned.

Their eratta sheets are shorter but I've run into a number of problems that I've worked around with help from their engineers and a year later I still couodnt find any notes on them. I'm guessing they underreport edge case silicon bugs like almost all silicon manufacturers.

My last project used a STM32F437 with 100 mbit ethernet, just about saturating the connection at 80mbits while maxing out the processor to interleave the bits of all incoming data and bit banging every GPIO unused by peripherals to control 30k individually adressable LEDs at 45 fps which is just incredible for a $7-10 microcontroller. Then after a few weeks of field testing we identified half a dozen problems all resulting in nondeterministic failures of the DMA or MAC peripheral requiring a hard reset. I think the most problematic one, DMA1 or DMA2 stalling when they tick within 10-20 cycles of each other, is the only one that was added to the errata and still plagues the STM32F4x7 parts.

That said if you care about part swapability, developer productivity, and need a very powerful ARM that you're not pushing to the edge, the STM32 line of chips is a great choice.

Yeah, it's better now a days with CentOS 7.x releases than it was with the 6.x ones when it comes to hardware support - but I still had issues for example with suspend/resume not working and Virt manager having issues because the Haswell Xeons weren't tested with Centos 7. Minor issues but for desktop you prefer something that works great.
Don't forget that most lisps have symbol names available at runtime. IIRC MIT modified the early PDP-10s to have demand paging support for running ITS, so even Maclisp wants many kilo-words of address space.

LISP 1.5[1] did run on a 704 which had only 4096 words, but that's in many ways unrecognizable as a lisp of today.

[edit]
The 704 included up to 16384 words on the 733 magnetic drum (core was 4096), so that already is more space than what the parent has, and this is circa 1960!

Exact same experience. Development is easy and frustration-free. The team listens to the community AND delivers.

The platform is not just for playing around anymore, it has matured really well. See the case studies[1] - I, for example, love Hansoft X[2].

I think I would feel frustrated to have to go back to any other framework. Meteor is what web-development should be like. I'm not sure if Meteor is going to be THE platform everyone is going to use, but it definitely is completely changing the game and I suspect web-developers will be adopting the Meteor ethos.

10 MW (constantly running) is closer to 20 wind turbines, given that the average capacity factor in NY is ~24%

(The average wind turbine capacity factor in the Texas Panhandle is closer to 35% because it's windier there)
Would appear that the limit is similar - the "red zone" is for "(> 50 mSv/y)" (note "more than") -- and the sign at the end "Leaving the zone" reads 4.9 mSV/h. That'd be about 42.000 mSV/year -- if we assume constant dose. Or put it another way -- stay an hour and you're at the (safe) limit of exposure for a year.

As for all the comments on how nuclear isn't all that dangerous -- how much do we really know about people leaving 4-5 generations in an area with elevated radiation, eating produce etc? I guess we have some data from the Bikin Islands[1] -- but those levels might very well be much higher -- at least it's not an example of how we can live safely in a radiation zone.

Speaking of [1]: "The special International Atomic Energy Agency (IAEA) Bikini Advisory Group determined in 1997 that "It is safe to walk on all of the islands ... although the residual radioactivity on islands in Bikini Atoll is still higher than on other atolls in the Marshall Islands, it is not hazardous to health at the levels measured ... The main radiation risk would be from the food: eating locally grown produce, such as fruit, could add significant radioactivity to the body...Eating coconuts or breadfruit from Bikini Island occasionally would be no cause for concern. Eating many over a long period of time without having taken remedial measures, however, might result in radiation doses higher than internationally agreed safety levels." IAEA estimated that living in the atoll and consuming local food would result in an effective dose of about 15 mSv/year."

It will be interesting to see if removing topsoil in Fukushima will be enough for radiation to reach safe levels. Hopefully the water tables are safe.

For students going to a particular university, math SAT scores are inversely correlated with verbal. If students had a higher math SAT and a higher verbal SAT, they'd be at a better school (and worse math + worse verbal = worse school).

For debtors inside a certain grade, it looks like employment history and other creditworthiness metrics are inversely correlated. So I suspect that it's less employment length being an anti-signal, but rather within the grade people with short employment length have compensatory advantages to stay in that grade.
The biggest shortcoming I see compared to the other big players (AWS, Azure, Google), and it is something they don't mention, is that they only have one datacenter, compared to the several from the other big players. The pricing is quite incredible though. I suspect if enough people hop on board with this they will probably look into setting up another datacenter.

I am open to the idea that there is evidence we don't have yet, but based on the evidence we do have, the original poster's point doesn't seem likely, even with modification.

Ask HN: Should we file a trademark?
We're CodePen. We've been operating for 3+ years. A google search for our name yields 518k legit results. We've always operated under the assumption that we're the de-facto owner of our name. But, recently, someone used our icon which was included in a free icon set as the icon for their magazine.

We're looking into paying to trademark our company, but it seems kinda pricy and also seems to have little value. In fact, [LegalZoom] [1] says "you are not required to register a trademark to achieve some level of protection".

Can anyone here explain to me what we'll really get from going through this $900 process?

Wow, this looks really nice! Are there any plans to expand the CI? The markup looks mostly job oriented, so I think most of the semantics would seem to need to be captured in scripts.

I've had this experience a few times and every single time it was mentioned on the Groupon, I actually checked out the menu before hand, and bought or refused the deal there and then. This isn't really unique, you buy a specific deal so you get that deal's menu, Groupon rarely sells some kind of carte blanche 20% discount card on whatever the company offers which seems to be what you were expecting.

I've also had Groupon redeem me for stuff that I had no right to in the TOS but was morally sensible to do.

There are quite a few things I criticise Groupon for but they've always been pretty transparent about their deals and willing to right any wrongs in my personal experience.

I agree - factory farming and even most "humane" farms are horrid. It would be better if we didn't eat meat (for our health, the environment, and ending world hunger). Then a smaller number of these animals could be pets or live on nature preserves.
I see the sentiment too

"...I could assess the effects of the power station failure and understand the scale of the tragedy, especially the tragedy of the evacuated residents, in a better way. This was a way of drawing my own conclusions without being influenced by any media sensation, government propaganda, or nuclear lobbyists who are trying to play down the effects of the disaster..."
Yeah, I ran across "You must agree to Apple Terms and Conditions" when running command line make after an Xcode update last week.

So, then you have to run sudo make to invoke the global license agreement console interface, then you manually type 'agree', then it runs the original command, except now you're running under sudo. In this case, that means it ran make as root, leaving root-owned artifacts all over my source tree.

It doesn't permanently go down. But if that single seller is selling at way under the previous market price, that is what everyone is going to be paying until they run out of their supply. If this lasts long enough, it could be enough to drive entities dependent on copper production out of business or into a collapse as the price they are forced to sell at isn't profitable. Once that point is reached it doesn't matter if the price goes back up when the single seller runs out, the damage has been done.
