"Our belief is that if someone doesn’t like them, and they won’t click on them, any impressions served to them will only annoy them-- plus, serving ads to people who won’t click on them harms campaign performance."

^^^ so much this.

there's this implied assumption that everyone using an adblocker is lost revenue, but a lot of that is going to be shitty ad impressions that never lead to clicks.

like it or not, advertisers can't actually put a gun to my head and force me to click on an ad and buy anything.

even if its a targeted ad that manages to engage me (coincidentally this did actually happen this morning with an ad from one of the rare newsletters that i've allowed to be sent to my e-mail inbox) then it probably doesn't work the way with me that advertisers want it to. i managed to find a product that i was interested in, but it was too expensive for me. so i did a "brandX vs ..." search on google to find brandY and now i've bookmarked the product their competition sells which seems to be more in line with my budget...

if you want to 'game' my purchasing habits you'd be better off not advertising at all in the classical sense, but instead send your product to review sites and/or just buy reviews in order to saturate google results. however, when all i see is obviously bought off review sites i'll go looking for relevant forums and look for user threads. by far the best thing there is to have a social media presence and have a staffer that surfs through forum sites and answers questions.

plus, you know, just have a good product for a good price to get people talking well about it... i realize that's some fucking crazytalk there though...
I think there are quite a few people who fit this bill, many of them on HN. You could reach out to some of the knowledgeable people in the HN threads related to Node/Angular, and ask if someone would be willing to have a look (same goes for good blog posts). There's also a YC Company called Airpair that works with a lot of good folks.
How do you run an efficient server-side search without maintaining a parsed index? I have 40,000 emails in my inbox. You want this to be linearly scanned everytime?
This will be popcorn time for those using Gmail for business.

I have a plugin in Thunderbird that shows the DKIM status of incoming email as gray/red/green, meaning no DKIM/DKIM invalid/DKIM valid. Most of the email I get from business accounts (usually on Exchange), including those from the company I work at, have no DKIM. (Yes, I've complained to the ITsec dept. They don't even have SPF set up...) Of the rest, surprisingly many have invalid DKIM sigs.
Quitter is someone else's interface to GNU social. You'd have to ask them about it.

I'm not sure if the founders of email would care for names like Thunderbird and Icedove, but you'd have to ask them.
As an US citizen I haven't heard or seen it directly ever. I always thought it was a British "gap year" thing.
Your description is very similar to what I experience as well, but I only get to go once or twice per year (the nearest center is about two hours from my home). I always get it coupled with a full body massage just before, and my last visit was just this past Saturday.

This time I was able to, for a short while, convince myself that I was floating on the ocean at night and could see the stars. A very peaceful experience.

The outside world feels so much more harsh, sharp, and bright after a session.
I don't know about self-repairable...yet. Mine's still under warranty, but that's almost up and I haven't had to use it.

I do use it plugged in most of the time, but I suspect that the review is spot on with the battery life. I maybe get a little more since I don't do much in the way of video, and I have my screen dimmed and my CPU in passive cooling mode.
Hopefully 3kPZS and the other pheromones don't affect native fish species on their stream migrations. Has this been tested yet?
Right. In the beginning, for the first few years, it did approach 'tick boxes on a form' from time to time. Note, though, that each partner is free to answer each question in any way they want to. Sometimes, it was "Uh, nothing surprising. What I really want to talk about is...."

Some ceremony led to highly consistent, timely communication. The latter is the goal, the former is just a tool.
As long as the good ol boy's network exist - people will always want to go to Ivy League and other prestigious universities. It will continue till the top CEOss graduate from "Southern New Hampshire University"...and I doubt shareholders and board of directors want to nominate a CEO from "Southern New Hampshire University" so you probably want to be a founder.

This is the press release that I received: https://ghostbin.com/paste/hdj3j
By including extra information testers can't just be coached or memorize apply this formula when you see this kind of question and the test shows they're actually understanding more real world problems and how to take what they know and how to apply it to a problem where everything hasn't been stripped away for you. If students are tricked by the simple extraneous information it shows there's a gap in their ability to take information and use math to answer a question about it. That's an important thing to evaluate.
Title is misleading.

As the Internet chips away at the practical reasons for limiting the student population, the real reason Yale limits the size of its classes will become more obvious.

Decreased barriers to entry of getting a degree will draw attention to the fact that it is (and arguably always has been) 20% about what you learn, 80% about who you meet.

MOOCs are not going to disrupt prestige, they're going to make it even more important as a signal in an increasingly noisy market.
Yes, that's what I wanted to say too. Perhaps LinkedIn's value of advertising is lower than that of Facebook, but it is still worth something. If the demand for ad slots drop on a particular network, the price of those slots will drop and this would attract marketers back to the ad network again.

If anything, Facebook is in a worse position than LinkedIn when it comes to coping with an economic downturn.

Financial crashes kill hype, not value. The article's pro-Facebook argument is centered around hype, not value.
I get 5-6 hours with Windows 8.1. I have a dimmed screen and passive CPU cooling when on battery, and I don't do much video.
I'm curious as to why ligo is the only project ever mentioned, particularly given that they have to work with virgo and geo600 to be able to triangulate their observations - a two axis interferometer only gives you partial information.

The Guantanamo in New York You're Not Supposed to Know About
This. Behavior is much better these days but dirty schedulers and ports are still the first places to consider putting C code. Only when you know you've got a solid implementation should you upgrade it to a NIF.

A short note on how hard this is: Until recently in 18.0, there were many BIFs (built-in functions that are part of the VM) that could possibly cause the same scheduler collapses. If the VM developers don't always get it right, the chances that some C code will, is very small. Tools like QuickCheck can help in testing the inputs and outputs but it's hard to setup complex VM stress states and thus very hard to make guarantees about NIFs.

While there is definitely overhead, I'd say regular external "ports" (OS-level subprocessing) are quite underrated from what I see in more recent Erlang code. There's a lot that can be done this way if port communication is carefully designed.

When people say "full stack", it means something very specific to me.

It means you can do both UI and server code, so you have a wide variety of knowledge in the many competing front-end and back-end frameworks out there, but you are not quite an expert in anything. At your last job you learned all the magic incantations of jQuery, Rails and MySQL, but but today you are expected to learn all the magic incantations of React, Node and Mongo. Specifically because you are expected to change your toolkit quickly, you do not dedicate any time to scratching the surface.

Certainly when hiring for "back-end developer", I expect deep knowledge of OS- and DB-level concepts like indexing and garbage collection.

Likewise, when hiring a "front-end developer", I expect deep knowledge of various mobile, desktop and tablet devices and the behavior various browsers exhibit on them.
yeah but look at the outages, provisioning of something is broken every other day. this has impacted my startup already multiple times, sadly.
I don't think that's true. The MBA class at Colombia is 700 people. Every year.

That's not a social network. It's a number of social networks. It's inevitable that you'll only connect with a smaller number of classmates, and AFAIK classes are even organized with that in mind (the whole generation is split into smaller groups that then have classes together).
I share the same feeling about MOOC in general (whether prestige, or not).

It's like saying online porn will replace sex - since at the end, you orgasm.
Why I'm Bullish on Lagos and Nigeria's Tech Startups
While it does seem like they're doing well and they have gotten some very nice backing from the NYT, I would also like to know what their revenue is. They throw out the number of users everywhere, but they don't mention the important numbers like how many are actually paying and how many are paying with regularity. It just feels like they're hiding behind a high user number.
I think it makes it easier to add contributors. Git doesn't allow a user partially access a repo so Paul would add a few people only contributing on one script. I added some really talented contributors :)
The repo under my name doesn't mean it belongs to me. In fact it belongs to the public. Everyone can contribute to it so everyone is the "owner". That's how I see open source projects.
I don't mind giving it back to Paul. I did it only because I needed it. I believe a lot of people would want it more accessible too.
Nope.

A ball of radius R around Earth contains R^3 stars. The angular size of Earth as seen from each star is 1/R^2 or more. So the total light coming to Earth is proportional to R. As R goes to infinity, you get Olbers paradox.

A lot of fresh college graduates travel for a bit before starting their job. Anecdotally, all of friends used money from past internships/summer jobs and signing bonuses to pay for their trips. It really is not that expensive to travel if you choose the right places and purchase tickets well in advance.

Everybody repeatedly says this while ignoring his behavior during and after obtaining the information, which is what he was really convicted on. He said so himself.
It's not quite that extreme. Google needs publishers so they won't try to squeeze out "reddit" in this example. It's more that they or Facebook or whoever will charge a tax on every impression our hypothetical publisher sellers, reducing their take home revenue slowly over time as the fees add up and increase.
> Is this really not obvious to people? It's about subtended angles - simple geometry.

If the universe is infinite and filled uniformly with stars, the 1/r^2 falloff in the radiation captured from each star is cancelled by r^2 dependence on the number of stars at radius r. So as you integrate r from 0 to ∞, you accumulate an infinite amount of radiation.

Is this really not obvious to you? It's all about infinitesimals - simple calculus.

The Cats in Our Lives
I've had a long career building products, and noticed a trend. When I build things that other people say that people want, they have been failures. When I build things that I want to use myself, other people tell me (almost without exception) that it will be a failure, yet they turn out to be successful.
This author seems to think the value of prestige arises from nothing; as if the fact that someone can get through one class on open courseware means they are equally qualified as any other graduate. One quote in particular stuck with me "few students are accepted to Yale but almost all graduate". What exactly did he expect? Why would admissions accept people they think are unlikely to be successful? The whole article is written as if candidates are chosen by a simple dice roll, uniformly taken across the population (mirroring those who now have access via the internet).

The value, from an employment standpoint at the very least, is not what you learned in school, but the reasons you were selected to participate in the community doing the learning. The elite institutions spend considerable time and expense collecting a curated group of top performers to a single location. From a creative and developmental perspective this is huge for the students. From a signalling perspective this huge for employers.

My prediction, perhaps as laughably misguided as I think this article is, is that the paridime shift will come from employers. As taboos against training wear away, and groups begin to see how much cheaper it can be to hire and train high school graduates the demand for college graduates will abate. This probably won't effect the Columbias, or the Yales of the world, but will likely eliminate most of the hugely expensive less prestigious institutions.
This is such an elegant way to phrase my general sense of frustration I felt reading certain exchanges here. Thanks =)

I have another similar story! This one kind of blows my mind.

In 1978, Corpus Christi College in Oxford, England was being renovated, which involved breaking down a wall that had been standing for centuries. When they broke open this wall, they found that there was a leaf from a manuscript dating to the 16th century. It had been stuffed in there as a sort of building material.

On this leaf was music, which was quickly identified as being a fragment of a piece by Thomas Tallis (c.1505 - 1585) called Gaude Gloriosa. The piece is known because it survives in other sources. It's pretty popular among music from the period and several recordings of it have been made in the last 50 years.

But what was unexpected is that the text on this leaf was not the same text as we have in the other sources. This text was in English instead of Latin. Clearly the composer had reworked his piece to fit a different text. But what was this other text? Nobody knew, and the pages they found in this wall were highly incomplete, so they only had a small fragment of this alternate text.

The mystery wasn't solved until just last year (2015). A British scholar named David Skinner typed the fragmentary text into Google, and out popped an excerpt from a book. It turns out the author of the text is Henry VIII's sixth and last wife, Katherine Parr. 37 years after the discovery of the leaf, and almost 500 years after the actual event, Google allowed scholars to connect the dots on this mystery.

(I'm not 100% sure whether the search that revealed the mystery came from Google books or the regular Google search, since the scholar who did the search didn't specify. But since the complete works of Katherine Parr are on Google Books (https://books.google.com/books/about/Katherine_Parr.html?id=...), it seems likely that it was a Google Books search.)

By the way, this whole story is being published in an upcoming paper called: ‘Deliuer me from my deceytful ennemies': A Tallis Contrafactum in Time of War. The abstract is available here: http://www.tudorpartbooks.ac.uk/media/sites/researchwebsites... (scroll to the bottom)

The problem with atomic clocks in general is that they have very good short term stability, but not-so-great long-term stability. So they are very good at measuring the amount of time that has passed between two events, but not as great for telling you exactly what time an event happened.

The other problem is that there's not really such thing as a single, true time. Precision timekeeping is one of those places where relativity matters -- differences in altitude and the geology of the earth under your feet at a particular point change how fast any particular clock 'ticks'.

So to accommodate these differences, if you want events to be synchronized across multiple locations over a long period, you both need a single agreed-upon "current time", and some way to get information about that time information to the sites that need it.

You could surely do this with directly connected wires that were very carefully measured, but that gets expensive very quickly. The GPS system already requires super-precise time just to function, so it makes for a great distribution mechanism of "what time is it" information, where the people running the GPS system are bothered with all the details of figuring out and standardizing a single time, and you 'just' have to listen.

The GPS folks also keep track of things like how fast the GPS standard clock is drifting from the UTC standard clock (since no two clocks will agree over the long term, period). And this is actually where the problem happened -- Two of the parameters broadcast (A0 and A1) were incorrect, and it's these parameters that are used to specify the current time difference between the GPS master clock and the UTC master clock (the GPS master clock is disciplined to be as close to UTC as possible, but is always off by a minute amount, and that's what A0/A1 represent).

Pretty much it boils down to, much as it is in distributed systems, "there is no now". Even with maximum care and the highest quality clocks, there's really not a definition of 'now' that's consistent across more than a single location. GPS is currently the closest thing we have to a globally-distributed definition of 'now'.
That was just precious.

For what it's worth, there's a lot of 24-bit-capable terminals that aren't MacTerm. Even xterm supports the 24-bit-color sequences, although it picks the closest entry in its 256-colour palette rather than using the 24-bit colour directly.

Also, you seem to be assuming "xterm" supports 256 colours and everything else doesn't. The best way to figure out how many colours the terminal supports is $(tput colours). tput also looks up other useful sequences; you can "tput bold" to turn on bold mode, "tput setaf 12" to set the foreground to colour 12 (bright yellow), "tput sgr0" to zero all active formatting, etc.

So I'm not really sure what your standing point is anymore. You yourself admit [0] that children and adults don't have the same contractual capability. Your example relies on a ridiculous presumption which exactly proves why minors are not considered capable. And now you're on to people regretting financial decisions, to which my response is, who doesn't?

The information is there, if they do the math. Failure to crunch the numbers is, in my opinion and in the law's, not an excuse to void a contract. Changes like credit card statements showing the results of paying only the minimum payment only do the math for you, not relay novel information. They are only valuable in the sense that people can no longer not do the math and remain ignorant, because it is already done for them.
