I feel like this journalist was struggling to understand the nature of different kinds of databases.

> document-oriented databases (where different types of data are stored in one unified document instead of a bunch of tabular cells)

There isn't one document, and typically documents aren't "unified" in the sense of having an enforced schema.

> columnar databases (where data is laid out in key-valued arrays)

Er, no. Where data is laid out in columns, to speed up aggregate and analytical operations.

> (Confusingly, the NoSQL name corresponds to "not only SQL" rather than "no SQL.")

Backronyms ahoy!

> But the thing about abstraction in computer science, whether it's a high-level virtual machine-based programming language like Java or a bare-bones Unix shell, is that it always has a cost.

So does hard-baking a single storage and access pattern, which is that you get it wrong and have catastrophically slow access and aggregation times. A relational database is a generalist, query optimisers are generally good at guessing how best to traverse a normalised schema and the last time people used "abstractions are too costly!" as a serious argument it was in the days of rewriting desktop apps in assembler.
I think it's called a paradox (rightly), because it's not immediately intuitive for most people.

As the same language. I believe it is uncontroversial among linguists to regard spoken Hindi and Urdu as regional dialects of the same language. Their writing systems are radically different, of course.
I deal with this all day every day working with advertisements. A lot of money is spent trying to detect "bad users" and/or "bots" (usually the same thing). I'm talking hundreds of thousands of dollars, if not millions a year in some cases.

I'm actually working on developing a system to track browser analytics and usage to detect if it's a person on the other end or a bot.

The quick solution of course would be to have a captcha when viewing ads on sites so the advertiser could confirm it's actually a legitimate user, but there are users that are doing everything they can to not be tracked/or view ads, so what incentive do they have to confirm they are a human just so they can be targeted for advertisements? That's why there are companies trying to work behind the scenes to see if the browser is a legitimate session, or a bot session.

Companies looking to buy advertisement space are really honing in now on bots, because it's become such an issue where server farms are set up that will automate views on pages to inflate profits, or like in the case of the company that runs this script on NYtimes, to see if the user is viewing the page through a legitimate viewing session, or if the user is running software in the background of their computer pushing page views automatically.

I could probably talk all day long with this, but advertising is a huge HUGE market. There is little to no day-to-day talk of the users that are running ad block on their computer, it's a low percentage of the actual users we are running into. The large talk is the people that have created botnets of hundreds of computers to push thousands of fake impressions and how to handle that.
You would think so, but unfortunately it's really just not that common in the business world.
Also not that simple because of dialect continuums,
see https://en.wikipedia.org/wiki/Dialect_continuum

In the case of french, say:

- Metropolitan and Canadian might understand each other

- Metropolitan and Sub-Saharan too

- but Canadian and Sub-Saharan not so much
Falling behind was never IEs worst 'feature'. Standards compliance, security and speed were much bigger issues.
Nobody[1] complaining about these kinds of privacy issues is talking about the 2nd-party service you are talking to knowing about the requests you explicitly make for it's data. That is the expected transaction, even from the perspective of a non-technical user. (if you want a youtube video, you're going to have to ask youtube for it, and youtube probably logs that request)

The problem with CDNs - and google analytics, facebook "like" buttons, 3rd-party ad networks, etc - is that they are not, from most people's preservative, an expected part of the transaction. They are a 3rd party eavesdropping on the conversation.

In the case of some of those eavesdroppers, such as CDNs, GA or (to a slightly lesser amount) Facebook's "like" buttons, there is also the serious problem of aggregation. Cloudflare and Google are both in a position where they can aggregate your browsing history from not only youtube, but also to a very large percentage of the network. This is easily enough information to make the mining of very personal data, including data that you never divulged directly but can be inferred with the various machine learning[2] techniques that now exist.

Also, the intent of the people at Google or Cloudflare doesn't really matter. I'm sure most/all of the people working at those places are currently well-meaning. The problem is that once data is recorded it stays around forever, so the question isn't if the people currently at Google or Cloudflare would misuse that data, but if anybody with access to that data in the future would misuse it. Allowing personal data to be aggregated creates a temping target for both people that want to profit from that knowledge and governments with national security letters.

Depends on how you count, if you count all words, then it would be much much more than that, like 99.99% because of very specialized words like "mononitrate" and the like.

But in common use I wouldn't be surprised if it was 98% or less

consider words like "pissed", "pants", "suspenders", "fag", "chips", "bisquit", "jelly", "pavement", etc.

they mean different things in British and American English, even though etymologically they come from the same source

Someone on a train once asked Paul Theroux whether he might help translate an American word. "Sure, what word?" "Huacha" as in this example sentence: "Huacha gonna do if the rains don come".

Counting differences between dialects involves a lot of boring questions about which contractions, changes of pronounciation or grammar etc. count and which don't. Does "I'm like" in the sense "I say" count? There are too many low-value questions to really get neat precise numbers.
That's not true, otherwise it wouldn't be called "Czechoslovakia" - the name itself implies there's a Czechia and a Slovakia
Actually i believe its only from the "www" subdomain. Take a look at the robots without the "www"

In fairness, what I've written is only a very small facet of the larger set of problems I face on a near daily basis - a lot of which I'd really rather not write about (mostly out of embarrassment, some of which purely because of the massive sense of failure I experience daily).

I'm not saying you are one but ADHD deniers tend to dismiss symptoms described in isolation off as "oh this is normal". Without the ability to describe in coherent way how deep the rabbit hole actually goes, many people with ADHD suffer needlessly when trying to seek help.

ADHD symptoms are often described as "everybody experiences the symptoms to at least some small degree, perhaps in combination or maybe one alone, but a sufferer is where they experience the majority of the symptoms to a massive degree on a daily basis". In a lot of ways, it DOES look normal. What isn't normal is how extensive the symptoms are and how much of impact they have on daily functioning.
I do something similar, and I'm very chaotic, not at all structured. When Im doing something I have my notebook open, if an idea pops into my head I write it down, maybe make a few notes about it, then go back to what I was doing before. Whatever I'm currently working on has a star next to it in the notebook. And once I finish I cross it out (usually). Its not organized like a list, basically just a brain dump. ( Examples of old pages: http://paste.click/VvnUdA http://paste.click/RZyWLG http://paste.click/CsVaoa ) Doing it in a text editor would be just one more thing to get distracted by, and it doesn't really work for the brain-dump/brain-map style, since spatial relations between what I write has significance. This way instead of going off on a tangent I can finish what I'm actually trying to get done, but still keep track of the unrelated ideas/thoughts.

Obviously it won't work for everyone, but it's boosted my productivity massively, and I'm the furthest thing from structured and awful at context switching (Well I'm great at switching, its the switching back that I'm bad at :) )
I use dillo and netsurf for that. Both are quite fast, dillo is the faster one, netsurf's layout breaks less.

Dillo is freaking fast, once you try it you start to wonder where the web went all bloated. Of course its layout engine is quite dated, AFAIK no HTML5 support whatsoever and I think there are many layout bugs too. I use it to load up huge static html pages, they just kill Firefox or Chromium on my netbook. It's certainly nicer than lynx, sometimes you want to look at images too.
Take a look at the robots file without the "www" subdomain. Its likely to prevent content duplication/push for only the non "www" url to appear on search engines.

I'm actually psyched about Palo Alto's app-id and Snort OpenAppId that maybe firewalls will start allowing things through by behavior instead of port. Then we can have the internet back the way it was designed.
I just recently decided to study film editing a bit deeper. Here are two classic reads that I highly recommend:

On Film Editing Kindle Edition by Edward Dmytryk (http://www.amazon.com/Film-Editing-Edward-Dmytryk-ebook/dp/B...)

In the Blink of an Eye Revised 2nd Edition by Walter Murch (http://www.amazon.com/Blink-Eye-Revised-2nd/dp/1879505622) (sadly no Kindle version exists for this one yet)

Visa Denial / Lobbying for citizenship
So I got denied a visa in America once due to very poor academic results. I had studied there for 7 years and dropped out of school 3 times. The first 2 times I reapplied back i got reaccepted by the school and the visa officer.

The last time I reapplied back about 3 years ago, I got accepted by the school but rejected by the visa officer who told me to only reapply back when my personal circumstances have improved. I did not have any criminal convictions, got deported or got in trouble with the law. I also did not overstay my visa at any time to the very best of my memory allows.

Hypothetically speaking, if I create a very successful startup like Apple that has a lot of paying users and hires a large number of American programmers,(i.e. I build the prototype in Singapore and put it on the web , on Facebook , Twitter and on hacker news to get users to test the product), do you think I would be able to lobby and apply for citizenship once I have proven to have added great value to the country ?
What isn't true? That the two languages are incredibly similar? There's less difference between them than between American and British English. Some words are pronounced differently, and they have different words for certain things, but it's no different than Americans saying elevators and British people saying lifts. Same thing.
I once, involuntary, went without sleep for around 72 hours. I was at a music festival and we were either pulling through the night or I couldn't sleep because of the noise. When the time came to go home, I really felt pretty good. At that time I had been awake for around 60 hours. My body was tired and my thinking was a bit sluggish, but nothing too bad...

Until I got home and tried to sleep. By then I was feeling dead-tired, but I simply couldn't sleep. This wasn't your average "Oh I can't sleep, guess I'll do something else and try again later" case of 'insomnia'. I was so extremely tired; all I wanted was to sleep. I started having hallucinations much like the early stages of a mushroom trip (minus the fun). My eyes couldn't focus, I couldn't think.

Finally I managed to fall asleep (while constantly suppressing panic attacks; something I've suffered from in the past and know how to deal with now). I had lucid dream after lucid dream during that sleep. It was very unsettling as I got the feeling (during lucid dreaming) that I wasn't getting any "real" sleep and I'd go insane.

All in all the lucid dreaming aspect was pretty cool, and in retrospect perhaps worth the unsettling experience of being awake so long. But I'll never ever want to repeat that experience.
Without knowing your code, I can think of a performance hack to get the running time of f() down to less than 10% of the time.
Read Paul Graham's essays, Start Small Stay Small, personal MBA, Lean Startup, Zero to One by Peter Thiel, 5 hour Workweek, Rework by 37signals. All of these are fantastic reads. In no particular order. Many of them available as audiobooks.

If you want to start a startup I would advise you to come up with an idea and start working on your product. Learn the necessary technology as you go. You really don't need to know so much on the "business" side of things when you start.

"How to Get Startup Ideas" by PG and Start Small Stay Small really cover 90% of what you need to know when you begin.

Sorry, can't recommend any videos, I guess How to Start a Startup are the most useful ones.

Maybe 10% of the Haitian population speak French. Everybody else speaks Kreyol. There may be some Haitians who can't speak Kreyol at all but very few.

African French is very close to metropolitan French because the language is less than 200 years old in Africa. You see the same effect anywhere a language has spread recently, there's much less divergence and variation.

Most Germans are bilingual in Hochdeutsch (Standard German) and a local "dialect". The question of whether a given speech is a dialect or a language is a political one, not a linguistic one.
Well, "Asian" or "European" or "African" are not languages either. Why would "American" be? ;)

Aha! So the web view "redirects" back into the app using an app:// link -- and because you're accessing that web view within the app itself, the redirect is captured within the app. Smart. I assume there is some sort of delegate thing that handles the browser events? Would it intercept the deep link or does that hit the app delegate?

Thanks for the awesome insights by the way.
Depends on how colloquial you get. For fornal/poetic use, they are vastly different.
Totally agree with you Egusa. Perhaps the key thing is to know which publications/sites you are targeting and what counts as 'news' for them. Traditional news outlets (eg TechCrunch or InfoWorld) only want something that is substantive and new - the end result. Content campaigns are often more informal - about sharing the journey.

A content campaign aims to inform a much wider base of people. It's best done ahead of any specific traditional 'PR campaign' for a launch. An easy way to do this is to create two lists of contacts: for your content campaign you might target amateur bloggers, industry influencers and your existing advocates.

Vocabulary constitutes a language "façade" and it is often interpreted as the key differentiating factor between languages. Most linguists agree that the language is based in grammar and rules for creating sentences.

That being said, official AE and BE are pretty much identical and the same rules apply on both sides of the Atlantic. It is only logical that different words are used, because of the different contexts that people live in, but that doesn't mean that AE and BE are distinct languages.

Yes they can grab the IPv6 address but IPv6 has a privacy extension to cater for this. It will alter your local IPv6 address periodically. You could configure it to update every hour and effectively they'd be thinking you were a new PC on the network.

IPv4 you'd have a small range of IP addresses but with IPv6 you can have a different IPv6 address each hour if you so choose.

The only precise name is MDMA.

There's also "Molly," which is the street name for pure MDMA. (Though: most terms are tied to a specific geography.)

...nor would they know how to chemically identify if what they
bought might contain MDMA.

True, but that's not unique to MDMA users. cf. the heroin in the Netherlands that was being sold as cocaine, and which lead to several deaths.

Organizations such as Dance Safe have existed for decades (in the U.S. at least) to let people test their drugs to make sure they're ingesting what they intend to ingest.
It also applies to how many of us extract excellence from ourselves. Working intense hours, loathing ourselves for errors, losing our lives to release some app which is probably shitty and even ultimately meaningless to humanity when you allow yourself to think about it... :)

Upsert in Slick 3
Really? I hate the CS3, I find it terribly designed. That's not to say other places are worse. The thing I dislike is the feeling you get: "There you go, we've built you a superhighway, no more complaining, and make sure you get out of the way of all the cars because they're more important than you are."

Problems with the CS3 and other similar routes include:

# Crossing T-junctions across right-turning traffic.

# Very narrow in parts.

# Swap from one side of the road to the other, taking you at a right-angle across moving traffic.

I get the distinct feeling that motorists and pedestrians around the CS3 feel they need 360 degree vision because they never know which direction the cyclists are coming from.

And there was also the case of Argentinian footballer Gabriel Omar Batistuta, one of the greatest strikers of all times, who had this to say about the time which followed the end of his career:

> "I left football and overnight I could not walk anymore. In two days I could not walk...I peed in the bed, the bathroom was 3 meters away, because I did not want to get up. It was 4 am and I knew as soon as I stood my ankle would kill me. (... ) "I went to see the doctor (specialist in Orthopaedics and trauma) Avanzi and told him to cut off my legs. He looked at me and he said I was crazy. I insisted. I couldn't bare it any longer. I can't explain to people how bad the pain was," he said

> At least to me, symptoms you wrote sound totally normal and not necessary ADHD.

The diagnosis is sometimes unclear to people without ADHD.

This is why generally it requires a registered psychiatrist to make the diagnosis and prescribe treatment.

People with the "predominantly inattentive" subtype (previously called ADD) typically go undiagnosed for long periods, or indefinitely. I was diagnosed when I was 32.
