I love this idea! I'm just a working programmer, but right now I'm trying to read through the highlights on research into temporal databases. People have been writing papers for 25-30 years, but it seems like not a lot has made its way into everyday practice or commercial products. Something was almost added to the SQL standard around 1997-2000, but was eventually rejected. SQL:2011 added something but it is pretty incomplete. I have been thinking I should put together a bibliography and a talk: temporal databases for web developers. A list curated by an expert would have saved me a lot of time!

I'm also (less professionally) interested in the overlap between the results from Turing and Godel. I would love a guide and/or annotations for Turing's "On Computable Numbers", because it is not easy going. Also a list of papers for quantum computing....
The point is that while circumstances like what are described in the comic are super rare. If we want to take into account ridiculously rare circumstances and call it "very realistic", why stop there?

Richard's parents sent him to personal trainer who taught him to be a track star. Paula had her legs chopped off by Islamic terrorists.

Richard's parents taught him to ground his electronics projects. Paula got struck by lightning 3 times.

Richard didn't like to go to the beach. Paula had her right hand eaten by a shark.

etc.

You can prove anything if you pretend wildly improbable freak situations are somehow representative of reality.

If you want to claim we don't have equal opportunity, I don't disagree. Some folks have advantages - e.g. the author of this blog post was born into the right race to get major bonus points in the educational system, had a mother who knew how to game that system, had US citizenship, etc. In contrast, all I had was US citizenship. Most folks don't even have the citizenship, and a large number of them are members of a race that's treated even worse than mine.

But if you want to talk about the practical significance of this - whether she's actually trapped or whether she just needs to work 10% harder - then you need to think about the details, which the comic gets wildly wrong.

Possibly it depends upon the audience.

Another possibility is that someone makes an error and then claims it was intentional testing.
"“It is very significant that these black holes were much less massive than those observed in the first detection,” Gabriela Gonzalez, LIGO's spokesperson, said in a statement. “Because of their lighter masses compared to the first detection, they spent more time—about one second—in the sensitive band of the detectors. It is a promising start to mapping the populations of black holes in our Universe.”"

Should you not expect to have a good work-life balance while at Netflix?
I don't doubt for many products you can assemble it yourself more cheaply with the input of time. But, a price factor of 2.25 over raw parts (COGS, cost of goods sold) is pretty reasonable overhead. It's not the best margin, but it's right within reasonable for paying for assembly, inventory housing, warranty coverage, etc.

"Blockchain is a stripped-down payments system" no, it's more and can be used besides payments.

And nobody believes it does solve the trust issues about actual exchange for goods or service.

Biggest thing I see (but I'm not too literate on bitcoin): once it works right it can't be stopped or taxed and still fly across the world through the internet.

The blockchain is really interesting in itself, but I know little about what is possible with it. One example I love though is the "proof of prior existence". You can weave a hash in to the blockchain and than have proof you already possessed the hashed information at that time.
> get their feelings hurt in non-illegal ways

Since the victims have very little trust[1] in the ability of the judicial system to handle this properly, the question about whether what Jacob did is legal or not is entirely unimportant. What matters is if there are victims who are hurt in more than just "their feelings". Given the number of credible people who have voiced concerns, and given that most of them also think that Jacob should get help, not go to jail, it seems very safe to believe the victims. The alleged damage done to them outweighs the possible damage that Jacob could face for being falsely accused by so many people.

Anyway, it's not like Jacob has any shortage of advocates in the public. He's charismatic, smart, likable. He'll be able to surround himself with supporters far more easily than his vulnerable victims can.

That's a good point. They're desperately trying to outmaneuver the cable companies. So far, they're doing OK, but not great. While Netflix is big, Netflix is not very profitable.

Netflix is becoming more like a cable company, with a limited menu. Total access to a huge back catalog has been cut back. Netflix, though, doesn't own the pipe.

Owning the pipe for TV is so profitable that AT&T more or less gives away voice and data if you get their TV service. Internet without TV costs more than Internet with TV.
Imagine the layout on disk for both a row based and a column based database...or see this link:

http://www.timestored.com/time-series-data/what-is-a-column-...

Now imagine which areas need read when you perform a query like "average price" for all dates. In row-oriented databases we have to read over large areas, in column-oriented databases the prices are stored as one sequential region and we can read just that region. Column-oriented databases are therefore extremely quick at aggregate queries (sum, average, min, max, etc.).

Why are most databases row-oriented? I hear you ask. Imagine we want to add one row somewhere in the middle of our data for 2011-02-26, on the row oriented database no problem, column oriented we will have to move almost all the data! Lucky since we mostly deal with time series new data only appends to the end of our table.

Scientists Detect Gravitational Waves for the Second Time
One of my favorite tips from the book that's stuck with me in the 10+ years since I've read it is the immediate breakthrough you'll have with someone if you pronounce their name correctly when you meet them for the first time, particularly if their name is uncommon to your culture. In the author's case, I believe it was a Greek business partner whose name other English speakers had anglicized down to "Nick." When the author pronounced the other man's name fully, the other man welled up and replied that no one had tried that in decades. I haven't ever had a response quite so extremely positive, but I have experienced sparks of surprised excitement from new coworkers with, for example, Polish and Indian names when I've taken the time to think about or learn how their names are more accurately pronounced.
The Dems have failed because they've largely signed onto the 'neoliberalism' philosophy too.

Considering some people spend 1-2 years as "junior" and then 10-20 years as "senior", you will get very different answers from "seniors" as they have varying degree of seniority. Most points in this thread add value.

The one thing which in my mind make people juniors well into their 40's is the inability to take responsibility.

Interesting to note that the y-scale on figure 1 is 10^-21 (units of strain). Measurement at that scale is absolutely insane. The power of good engineering, incredible optics, and lots of averaging.
You're overthinking it -- it doesn't make sense. At best, it's a sort of overblown rhetorical point drawing a comparison between one dislikable thing and another, at worst it's a conspiracy theory. (The conspiracy-theory read is basically "this is the first step towards regulating the internet so they can ban Rush Limbaugh" although it's sort of an Underpants Gnomes level theory. There's no step 2 to get you there, and in fact it's much easier to get to the content-censorship outcome via media-company control of the Internet.)

No, it just means there's a high probability that these events occur on a regular basis. Of course, "regular basis" really means we might be able to approach gaussian statistics within the lifetime of the experiment.

Maybe you're a bit too use to focused on the Bay Area/San Fransisco.

> low density and poor street planning of the past

You're just wrong about San Fransisco's population density being low. It is 21st most populated place per square mile in the U.S.[1].

As for you're argument that there is "induced demand" for traffic I would argue that there needs to be actual evidence for that (not a wired article). The fact is, lots of lanes create slower traffic[2], and the "induced demand" argument would mean building a bridge to no-where would suddenly make people come (which seems pretty false).

Further, if you are concerned about:

> I’m concerned about long-term sustainability

Being more distributed reduces the need to transport water (arguably the single most important resource) vast distances. The same can be argued for energy; renewable forms of energy such as wind and solar farms are often built great distances from cities, you can place them closer to residence using them in suburbs.

Not to mention, suburbs eventually becoming cities (or as populated as such). Meaning I really wouldn't worry about this "long-term," at least 50 or so years.

Regardless, that's not really the point though. My argument was that the suburbs have access to at least just as much as a city, at a more affordable price.

Sexual harassment is crime we all must take seriously especially the tech industry which is struggling get in more women.

But at the same time open blogs like these must be taken with a bit of skepticism too because it is one person's story. We must question if not assign malicious motives to the victim.

P.S. What can we do about such cases ?

I think entire tech industry can create a fund specially for victims of sexual abuse so vulnerable women could consult a lawyer for a very low price who will be specialized in handling such cases. The hammer of justice must be brought into picture as soon as possible. It is unfair that some women has to live with this burden for so many years.

Ask HN: How do I smarten-up my new house's heating system
I've just bought a house with electric baseboard heaters, and an "analog" thermostat in nearly every room. Previously, I've only lived with a single thermostat, usually programmable.

I don't care for the idea of purchasing and configuring 10 programmable thermostats, because I would like some central control, and it seems expensive.

I also don't want to rewire the house to run all thermostat control lines to a central unit.

What I envision is a central unit connected wirelessly to a number of "dumb" units, which I can replace the existing thermostats with.

My googling skills failed to come up with an answer. Honeywell makes a line called Evohome, but it's strongly suggested this only works with central heating.

Anyone have any other suggestions?

Ask HN: Is the “G2 Crowd” business software review website a scam?
They seem to be legitimate based off of a search. I initially clicked based a Facebook ad from them promising a $5 Starbucks gift card to take a survey based on what business software I use.

I took the survey and listed out the software I use and connected my LinkedIn and stuff like that. They then promised more gift cards if I individually wrote reviews for the software I listed (or other software, I believe).

I figured I would see if I received the initial $5 gift card before devoting any more time to writing actual, well thought out reviews. So I opted to wait.

Then I received an email weeks later:

"Thank you for telling us about the software you use at work.

Unfortunately, we were unable to confirm the validity of the information you provided during our moderation process, and therefore cannot accept your submission.

We manually check each submission and user profile to ensure the responses are authentic, first-hand feedback on software used by real business professionals. Thanks for your cooperation and understanding."

So that leads me to believe it's a scam of some sort. Possibly a data mining operation or something (I did connect my LinkedIn). If nothing else, I think it's bad business practice to entice someone with something to do work for you, or take surveys, and then back out.

Has anyone else had experience with this site?
