The system I have is wireless and despite being in a 3000+ sf home with many potential sources of interference, I have not had any communication issues. When a perimeter sensor, one that guards against intrusion, drops communication, the system will take action dependendin on whether the system is armed or not. If someone is home using the microware, the alarm is typically not armed; not that the microwave has ever caused an issue anyway.

I don't see why this is not the behavior for xFinity's system as well.
Why not using WolframAlpha? For example: http://www.wolframalpha.com/input/?i=food+ranked+by+potassiu...
I for one thought it was a pretty good advice for UI, especially for landing pages. A good landing page can make all the difference and it can be a pain/time-consuming when it isn't your specialty.
You are also missing the point that there is no indicator of communication failure, no log, etc.

In my fire alarm when the batteries are going dead there is a chirp that lets me know of a pending failure. The Xfinity alarm system could do that as well.

Instead the alarm system is worse than useless.

I can buy a box that always has a green light on it which is exactly what this "alarm" system is doing when there is an extreme failure.
LOL, just last night I was updating my start-ssh-agent[1] script for bash in windows to parallel the logic of the cmd file that comes with msysgit[2]. I spent hours trying to figure out a way to pass `/IM` to taskkill without it expanding out to `/c/.../IM` from bash itself... before finally finding a solution[3], when I stopped searching for a generic answer[4].

Painful to say the least.

it is probably easier to just wrap R functions as a subprocess in python. you would have to write some R code to do this which might involve writing to a flat file. i do this all the time in R wrapping up something like rgf and calling from within R. i have wrapped up python and called it from R using system. the same idea works for python as well. you could probably write some kind of general wrapper that would work for most of R's ML type functions.
Even so, having systemd installed on your system is infinitely better from the perspective of software freedom than having Windows 10 installed.

Just as a point of interest: Why would you convert a R program into a Python program? I can't think of any benefit in terms of speed or reporting?
I don't think it's a fake concession. There is academic value in far-out research that isn't relevent to industry, just like there's value in math research and in metaphysics.

The point the article tries to make is that if you're trying to research something relevent to industry, it's probably not nearly as valuable academically as something more exotic would be, so you'd better make a good effort to make it practically valuable to compensate.

Nobody is that much of a condescending prick to the person they're trying to persuade.

In context the line didn't appear condescending at all as I read it. A little sarcastic, that's all. The author made it clear that he doesn't think academics need to produce something that's actually used by consumers. And the author was/is an academic. If you'll allow me to speculate, it seems that you don't have the highest opinion of academics and so it seems possible that you might further think that in order to be valuable they need to produce a product that is economically valuable. If you read the "I know, crazy, right?" line with that attitude, I can see how it might appear much more condescending than it actually is.

This is not a "we need to talk" conversation this is a "I need to talk at you, so I can show off to other people."

This is a non sequitur. "This article isn't trying to persuade academics, therefore it is trying to promote the author's social standing at academics' expense". The author identified a problem and offered a potential solution, does that mean he also has to persuade? Your statement presents a false dichotomy, that he has to either persuade academics or shame academics to promote himself. I say that he doesn't make an attempt to persuade beyond identifying problem and solution because he doesn't want to bore the reader with rhetoric, nothing more nefarious.
My work laptop has one, yes, but it is closed and docked so I can use the two larger monitors on the desk. Ergo it is equivalent to not having a camera at all.
>dollar was near multi-decade lows ~2 years ago. oil was at near multi-decade highs ~2 years ago.

Yeah, that's exactly the correlation I am pointing out. Guess who started really blowing up ~2 years ago? ISIS.

More instability = less control over oil resources by the sovereign = cheaper oil for everyone else

Decrease the oil price, and you increase demand for oil.

Increase the demand for oil, and you increase the demand for the dollar.

Increase demand for the dollar and you increase its value. Basic economics.

6/7 of the richest companies in the world in terms of revenue are oil companies, and oil is primarily traded in dollars. You'll notice that when a country starts trying to sell oil in something other than the dollar, they go on the NATO shit list: i.e. Iraq, Iran, Venezuela.

## back end

- Servers running Ubuntu hosted at Linode (outages recently have been worrying)

- NGINX

- NodeJS & express framework

- MongoDB replica set with primary, secondary & arbiter

## front end

- BackboneJS

- JQuery

- gulp for build & deploy script

- RequireJS for modules

It's been going fairly well on the whole. This is my first web-site with a back end, so I don't have experience with Python, PHP, MySQL, etc... to compare it to. Given that, it's hard to say whether I'd choose differently if I started again. I would probably play around with PostgreSQL since a relational DB may suit my needs better. Also, MongoDB can be worrying. I added a replicaset member running the latest stable version 3 with the WiredTiger storage engine to try it out but it kept crashing - not what you want from a database! I'm still using the older, very disk-space hungry version 2.6.x for now.
Since you disagree with "Furthermore absolutely no viable public purpose can be served today by backdating new rules to past works."

I just would like to know your bases for your disagreement, and ask for some examples. Maybe there is a misunderstanding.
While I agree in general that opening up opportunities for academic-industry collaboration is good, I don't think it's practical for academics to work on problems at true industry scale. Academics don't have access to the resources, personnel, or funding required to do that kind of work. An academic lab can do many things of relevance to industry -- but not everything.

Google recently open sourced its TensorFlow plstform specifically to enable researchers (and others) to build upon and improve it -- trying to avoid the problem with MapReduce (where a bunch of clones came out that were, at least initially, inferior to the original).

I dunno, man. I write defensively as a default and consequentially nitpick every argument made for a position.

On the other hand, I am not adverse to changing my mind on a flip of a good argument.

If I get offended or defensive, it means that my beliefs aren't as ironclad as I thought.

There are some areas that I pretty much don't pay attention though.

Anything concerning creationism, global warming denialism, pro-smoking, god, etc.

Context is really important in communication. When speaking with someone face to face, you pick up on vocal intonations and body language to give you context to their speech. As well, knowing someone personally gives context to what they are saying.

On the internet, you have none of those things, only text. I think we are hitting a wall with our written languages because they can't adequately communicate context. Emoticons are a great evolution in this respect, because I can assign emotional context to some writing with a simple set of characters :).
I don't understand the point of things like these. You could choose any set metrics or variables that you want. How do we know these arbitrary categories are actually associated with a meaningful outcome? This is silly

One of the common methods people use to attack posts with ideas they don't agree with is to take the prose literally. This is much like the "work to rule" form of protest that unions use, and the "letter of the law" rather than the spirit of it, and of course all those "zero tolerance" policies.

Firefox Sync and Chrome password store are for users storing passwords. They are not hashed (because that would make it impossible to log into a site, because you need the actual password to log in, and a hash is irreversible). I don't know what you mean by salted, because as far as I know, salts are only used with hashes and these are not hashed.

Bcrypt, scrypt, and argon2 are for server storage of login information. The server does not store the actual password, it just stores a hash.
Determining which lights are occluded is non-trivial and can't be done on at a low level (too many checks) thus you need to precompute it on some level, but if different parts of the scene have different sets of lights visible you need to somehow abstract that to keep your parallel computations going.

All very doable but are the hard problems with the tech that should be solved before we say that ray tracing is solved.

Like 2nd rank California, home to 50 Fortune 500 companies ranging from Apple to Clorox to Allergan? /s

Also, diverse economy doesn't mean more innovative. Some companies like, say CVS in Rhode Island, can prop up a state's economy, but add little to the innovativeness of the state.

Which is fine by me - I consciously choose to boot into my gaming PC and start up Steam. My gaming friends are a small fraction of my friends. And spending habits are pretty easy as well - basically whenever there is a major Steam sale. And you are still able to play a lot of games offline.

My point with the above is that the risks are far less than with a general purpose operating system. How can I ever trust Windows as a platform for running the Tor Browser on? How could I trust any closed system?
But that's just market cap, which isn't comparable in any way to GDP.

Both are measures of very different things, and both are very different to actual money.
The Only Correct Script Loader Ever Made
Property-based checking [1] is pretty much the paragon of proving the mathematical correctness of a program short of a) using something like SPARK and Ada, or b) using Coq or Agda to formally verify, well, everything[2]. Formal verification is difficult but most of the rigorous proofs are done exclusively outside of the language in which they were written[3].

If you go to google finance and plot the S&P 500 for all known time you get a chart that goes back to 1975. I see three big humps 2000, 2007 and 2015. This is obviously not the most sophisticated analysis, but, there seems to be a pattern were the market gets over excited and then blows off steam. Maybe we are at the start of a correction.

The only thing that concerns me is that those market peaks/humps were due to humans getting concerned and changing behaviour. Maybe now that most trades are just computer to computer the Algos don't "know" to be "scared" and cool it we might keep going up till some epic event corrects it.

I am hoping it's a 1-2 year correction that goes down 50-60 percent. But, who knows.

Not to mention the HD projector/4K television, dedicated windowless room, comfy chairs, etc...

The point being that, yes, with enough time, money and effort you can of course build yourself a miniature cinema inside your home. But the idea of cinemas is that you don't need any of that to enjoy a movie in exceptional quality.

I live in a city apartment and have neither the physical space nor the dedication to get myself a professional-grade entertainment system. Does this mean I don't care about image details or sound quality? Of course not.

The social components of going to a cinema shouldn't be underestimated either. Watching a film in a crowd is a different experience than watching it with close friends at home - visit any midnight premiere of a movie with a decent fanbase if you need proof.

Depending on who you go there with, it can also be more than just the movie and be a part of going out in the evening.

The disruption seems like a loss of quality to me, where everyone except the rich or very dedicated would have to do with a significantly reduced experience tgan what is available today.

I have always been surprised they get so much UI praise. To me, it feels like the HTML frame that it is, and often confounds my expectations of how a native app works. It is definitely better than its competitors, but that doesn't mean it's all that great. Having said that, it seems like they've wielded the web view approach to achieve a great flexibility and development speed advantage, so it's definitely a valid way of doing things. But I keep waiting for them to switch to full-native now that they're well established and can afford way more developers.
Thanks for your comments here - really explained what this thing is. I didn't pick up on that from the blog post.
very true. 20 candidates with "perfect" subject scores would be an entirely different thing from the general math GRE.

I actually think you can miss few questions and still get an 800 on the general, with the "adaptive" computer test. Not sure about that though.

Actually I was yesterday thinking about rebuilding my old app for the web, but if your app works fine I'm gonna pick me an other pet project. :)

Anyhow, I signed up for a premium account.

I couldn't figure it out how I can terminate the account if I take the monthly payment plan. You should make this clear at the beginning of the sign up process and not at the end:

http://imgur.com/XFm13o9

and should also put it here:

http://readlang.com/termsOfService

I anticipatied some trust but I generally don't sign contracts without knowing how I can get out of them. This may scare the customers off.

If I were you I would do this:

- instead of building new features I would make the site look professional, this means all the boring stuff which makes you money, like easy sign up, better landing page (for that part you already have tons of advices here), a proper terms of servie, privacy policy, etc. and after that I would go hunting customers until I doubled the revenue

- or I would find somebody who has experince with the business side of this, I would share the profit with him (the 50% of something is better than 100% of nothing)

It is up to you, but if you want to stay a one man show you have to learn how to make online business. Otherwise you have to find a business guy.

Good Luck!

Why would you use the screen real estate on a "conversation" then instead of just showing the data?
that's right, but Jupyter notebooks have just one language each, they don't facilitate polyglot programming.
There's countless different indicators and investors don't follow the same ones, if any at all. Most people aren't computer programmers who have run historical simulations. Just because you know something doesn't mean that other investors do. For example I bought lots of Bitcoin when it was at $16, because I thought I knew something other people didn't, and I was right.

The fact is if you followed the indicators that I mentioned since 1950, your net worth growth rate would've increased at least 50% without even using leverage. Trends in the general stock market change slowly (the price doesn't look like random noise) and that's why it's predictable enough to beat a buy and hold strategy.
Mysql always seemed to be fast like a bike going downhill with no brakes.

Postgres has always taken a more 'solid' approach. One instance that made my jaw drop when I realized it: in the past (has this been fixed?), DDL (alter table, create table, etc...) were not transactional in Mysql. You could get 50% through a series of them, and find your database 100% fucked up.

That said, over the years Mysql has been improving too, for sure.
Hey HN, one of the authors here (that's me in the screencast). Let me know if I can answer any questions.
If all you care about is QPS, by all means, stick with MySQL.

People like myself use Postgres because it has a much richer feature set. See http://stackoverflow.com/a/5023936/270610 for some examples. Personally I find MySQL beyond frustrating due to its lack of… well almost all of those. Recursive CTEs in particular, but arrays and rich indexing are pretty core too.

Postgres's query optimizer is far more advanced too. MySQL doesn't even optimize across views, which discourages good coding practices.

The documentation is fantastic. Complete and well-written, covers the nuances of every command, expression, and type. MySQL's doesn't hold a candle to it.

Don't know what you mean about "unfriendly". Help is built into the command-line tool, and like I said, the documentation is fantastic. Maybe MySQL is a little more "hand-holdy", but I don't care for such things so I wouldn't know.
