If instead of enriching U235 you think of it as eliminating U238, though, then you've done half of the work.

That's the wrong way to think of it though. The right way to measure progress is in terms of Separative Work Units: https://en.wikipedia.org/wiki/Separative_work_units

If you start with 10000 kg of natural (0.7%) uranium and you want to separate it into 45 kg of highly-enriched (90% U235) uranium and 9955 kg of depleted (0.3% U235) uranium, then you will have to do 8800 kg of "Separative work units".

On the other hand, separating that same fuel into 3000 kg of partially-enriched (1.4% U235) uranium and 7000 kg of partially-depleted (0.4% U235) uranium only takes 1790 kg of "Separative work units", even though the increased concentration of U235 means that "half the U238 has been eliminated".

Isotope enrichment is an area where, to borrow a line from software engineering, the first 90% takes 90% of the time, and the last 10% takes the other 90% of the time.
"Usually" is a real stretch. ecstacydata.org's lab testing report analysis indicates amphetamines were present in under 5% of tests for the last 15 years.

Well, it's pretty trashy. The fact that the books are well-documented doesn't make up for the lack of writing ability (also, I think every book has the same sex scenes, more or less).

How do you defend yourself against somebody just mirroring the libraries?

I was just researching licenses for a similar business model (in a completely different field) and came to the conclusion, that it does not really work.

AGPL would somewhat work, but would still have the downside that commercial entities could use the software just for tooling and internal processes, which most software is used for anyway.

In my mind Open Source prevents commercial use of applications only if the software is very likely to be shipped to the client, for example Qt.

With libraries it might look different, because people just get used to them and want to use them everywhere.

I would be very interested to hear your input!
This is true. Communicating with New Horizons requires using the 70m DSN dishes. Of which human civilization has built ... 3. So monopolizing that resource for an entire year would be problematic. Instead the probe will send back highly compressed gallery sheets of all the images it has as well as a few pre-selected shots (some of which we've seen) which the science team will use to prioritize the data the gets sent back. Then the highest priority images will be transmitted using loss-less compression and the remainder will get sent over the remaining months off and one when the 70m DSN dishes aren't needed elsewhere.

Those portals are nominally for finding someone else of that race/religion - they don't prevent you from signing up if you're not a member of the group (I checked). That is the part that seems like it might not fly under California law - Jopwell is a business; so I don't see how they can legally deny accommodations based on race. I don't think the issue is with a company using Jopwell to find candidates, but rather with Jopwell telling white people that they are denied service due to race.

If you think that is OK, I don't see how you could be against a recruiting company that always rejected nonwhite candidates for placement (but didn't have that as part of their explicit mission).
SaaS I’m so confused
I've run A/B tests on this and seen meaningful higher conversion rates.

To answer your questions from my experience (dealing with a non-tech audience):

> (1) How many of these users just mark all of the newsletters as spam?

The deliverability and negative feedback for users who come in through the popover is not statistically different from users who sign up in other positions (bottom of the page, for example).

> (2) How many users don't realize that they can dismiss the dialog, and enter their email because they think that they are forced to?

We did some basic user testing and the vast majority of people had no difficulty with finding the close dialog. If this were the reason, I think it would be born out in (5).

> (3) Are you only making this distinction in the smallest way possible so that you don't run afowl of anti-spam laws?

IANAL, but I don't think there's actually any law preventing an email wall. We even tested one at some point but it did have a meaningful effect on bounce rate, and it did tend to get more undeliverable emails than the dismissable version.

> (4) Did the A/B test include a "No thanks, I want to read the article instead" instead of just a "No thanks" button? How much does that affect the number of sign-ups?

Why would a business do this? What business goal would including the additional copy fulfill?

> (5) How many of those users will actually open their newsletters vs. getting lost in the clutter of other newsletters that they automatically sign-up for?

In my experience, ~20% open the emails and then 40-50% click a link within the email. These rates were not statistically different for people who subscribed through popovers vs. less intrusive forms.

That being said, I still personally dislike popovers and never subscribe through them.

> I'm MUCH more likely to signup for your newsletter or follow you on twitter if you put links/forms to do so AT THE END of the article.

Unfortunately you're in the minority. Every A/B test I've seen shows popovers performing much better than end-of-article placements on all dimensions.
Wait, I don't get this. The Amex agent called the old phone number on the account. The person who answered gave some indication of being the account owner, but didn't answer quite as many questions correctly as the thief.

So what scenario is the agent hypothesizing? The person at the old number was actually the identity thief, and used the account for maybe several years without any challenge, before the actual owner changed the number back? That makes not the slightest bit of sense to me.

I think if the phone number has recently been changed, and you call the old number, and the person who answers can answer any question at all about themselves, you have to figure that's the account owner. Who else could it be???

The best part of the story is how he hacked the US immigration system to be able to stay in the US after serving his time:

> Factoring in time served and a reduction for good behavior, Naskovets got out in September 2012. He faced a deportation order that would have sent him back to Belarus. Representing himself in immigration court, he argued that he risked torture if sent home, based on his run-ins with the KGB. As a signatory to the U.N. Convention Against Torture, the U.S. cannot send someone back to a country knowing he’s likely to be tortured. An immigration judge sided with Naskovets. The government appealed.
Here’s where Naskovets’s optimism proved justified. While he was buffing floors in a county prison in Pennsylvania, his case had caught the attention of Stephen Yale-Loehr, a law professor who runs an immigration clinic at Cornell. With the help of Yale-Loehr and his students, Naskovets fought Immigration and Customs Enforcement in court for two years—and in October 2014 the agency decided to let him stay.
I assume that was a response to the ancestor comment about "charity donations, payments to friends and family, paying for little johnny's karate lessons, stuff like that."

FWIW, personal checks for religious offerings seem to be common and accepted (at least accepted enough that I've seen them in offering plates in multiple churches, and I've never seen any church tell people that they'll reject personal checks), so I think you're right on that front.

Anecdotally, I pay for my music lessons with personal checks, and I paid rent in my SF apartment, to an individual landlord, with personal checks sent via USPS. In both cases there are reasonable means to complain if those checks bounce.

How about not showing it at all until the person has seen a dozen or so pages?

As many have pointed out, most are unlikely to subscribe to the newsletter/install the app/whatever before they've even seen the site.

It seems like the least annoying way to do this would be to detect multiple visits (preferably over multiple days) and then ask for the signup. If the person says no, don't show it to them again for a very long time, if ever.

This is not that uncommon when optimizing code.

Your program is slow so you profile it, and find out that f() takes 99% of the time. So you work a lot to optimize f(), and re-profiling shows that now f() takes 98% of the time.

Doesn't seem that impressive after all the work you've put into optimizing f(), but your program is actually twice as fast :)

I was expecting yet another Myers-Briggs, but I found the actual test (36 questions, each with 4 aspects and least/most options) interesting. I don't know how effective it'll be at gauging employees, but I think it does a good job of minimizing opportunities for 'gaming' the test. Almost all the options are fairly neutral.

I took the test, but sadly, I'm not willing to pay that $50 to see the results!
www world really needs more www "browsers", particularly some more that do not implement javascript. Would it hurt to give users more choice and see what they choose?

> I mean, "the site the developers want to build" will invariably be a site with no ads whatsoever.

I think that's shortchanging developers. They know where the money is coming from and if the company has good incentive structures (ie. equity) want to make sure revenue grows as well.

Fortunately, developers are also aware of the cost which is associated with every third-party tool included on the page. That's why it's really important to include someone technical in any deal conversation as early as possible, and they need to have the ability to block a deal which would substantially degrade the user experience. They can also weigh different providers by their implementation cost to users, which is crucially important: a sales guy loves to hear "just one line of JS" but I'd much rather use a REST API.

The key to getting this sort of control and buy-in is demonstrating to management the fact that page load time has a direct effect on traffic (and thus revenue).
Many times during Rust's design process, I saw quotes like this:

"Rust is not the first systems language and will not be the last."

and

"Rust is a language designed for the hardware of today, not that of ten years from now."

Rust is just a stepping stone on the path to better systems languages. It's not the greatest language ever and it made mistakes, but it gets enough right to make it a very compelling option in the systems programming space.

Ask HN: Built an app but don't know how to take it to the next phase
I just spent the last year and a half building an iOS app, an idea that I have a lot of passion for. It's a social app, so the next step is quite the obstacle for me, I don't really know how to go about pushing it to the market. Its content requires a decent size user base so I've been considering trying to get some funding for help.

I haven't released it to the app store yet.

I've made a video demo of the app and have thought about sending it to....

questions:

-what direction should I go from here with these presented circumstances?

-would it be risky to send someone the video who has a lot of money and resources?

-should I fly out to san fran and start knocking on doors?

-should I scrap my entire plan and just try to do it myself?

Any advice would be greatly appreciated
Shouldn't it be impossible for a website to determine what files exist or do not exist on a local machine? That sounds like a serious security problem. It seems that no non-file:// site should ever be allowed to load a file:// resource, much less query the element for its size or error state afterward.
The QOTD seems to just hang sometimes. Anyone have any guesses as to why?
If you also include the methamphetamine row, that number is a lot higher, in 2007 in particular it was present in 38.6% of the pills tested. For contrast, last year only 33.1% percent of the pills tested actually contained MDMA.
> How about not showing it at all until the person has seen a dozen or so pages?

We actually tested that as well (though I think we did it after 6 pages). The conversion rate was of course higher than showing it immediately, but the users didn't open or click any more frequently. (Hence, showing "immediately" on first page load is better business-wise.)

> Does your A/B test detect how annoyed the readers are?

Haha, that is indeed why I pushed against this in the first place (if I hadn't, we wouldn't even have tested it so thoroughly). But the fact that such "annoyance" didn't show up in any metrics ultimately won me over.

One thing to keep in mind is that I've only tested with non-technical users, who I think are in general much less annoyed by this sort of thing than the typical HN person.

Without knowing exactly what your app does I'd say before taking funding or flying to SF you should start to get some kind of traction or a beta going with a user base to learn from. Also sounds like you are unsure how to market your app. If you need a certain size user/content base before your app is interesting you have an engagement wall problem. It might be a good idea to push installs by buying ads (twitter, facebook, etc.) on top of influencer marketing.

I agree with you. To take the original ruling a step further towards absurdity, why not make ISPs filter out any traffic even mentioning the word grooveshark. And don't forget those pesky cables running from an exchange to your house carrying those bits, why not force the local exchanges to filter that traffic. Computer monitor makers; how about forcing them to not display the word grooveshark.

The further and further you get from the origin (content producers/hosts), the more ridiculous the claim sounds. But the expectation is somehow different.

That's a serious stuff that could see many applications even in today's world.
Pretty much every port below 1024 is reserved for one protocol or another, but many of them have been obsolete for years. It seems that whoever was in charge of assigning well-known ports back then just handed them out like candy.

Well, who am I kidding? This is the same IANA that used to hand out humongous blocks of IPv4 addresses to anyone who asked.

Should we try to deprecate dead protocols so that low ports can be put into better use? Or have we come to expect that all new technologies will simply reuse ports 80 & 443, so we have no need to set aside new well-known ports anymore?
