Professional blogger or hobbyist?

My last 5 blog posts (robotics on Hizook.com) were exceedingly fact checked. But then again, I'm a subject matter expert: I have a PhD in robotics. Terrance Tao... also exceedingly fact checked (Fields medal winner blogging about math). Richard Lipton... same (famous computer researcher blogs about P vs. NP).

I know that's not your point... but not all bloggers are equally sketch. Some of us know what we're talking about.
I'm not suggesting they are all charming, some of them are pretty terrible, but that's the price you pay for having relatively free speech. While moderating the questions would eliminate posts like the one you linked, it would also eliminate ones which aren't terrible but are certainly "off the script" of what would be asked if everything were cleanly moderated.
However framework vulnerabilities offer a consistent attack surface which needs little analysis or tailoring.

The only vulnerability we've seen (ms11-100) was swiftly dealt with and would have been eaten by our up front load balancers anyway.

Regarding our application, our test load is 134,000 test cases and 220,000 lines of assertions. I can sleep well at night.
No, I think that's pretty lame too.
There are two common json gems, one if which is NOT updated when you update rails. json_pure does not seem to be updated to 1.7.7 automatically by 'bundle update rails' so if your Gemfile.lock shows your app uses json_pure (via some other gem's dependency in my case), you also need to run 'bundle update json_pure'
I find the argument a bit silly as you can say the same thing about Outlook.com and the anti spam features. All your works are on their servers and they "Read" them when they get and store the email.

>> That benchmark is for algorithms implemented in pure Python and in pure Go <<

Note that papsosouid needed to add the restriction "on benchmarks actually written in python instead of C" to avoid mentioning the 2 tasks where Python is shown as faster than Go ;-)
> Using the heater does not affect range in a gas powered car.

It typically does (though not as much as the chiller would).

There's two costs to using the heater:

1. The electricity to power the fan comes from the engine. I'm not sure how much of an impact this actually is (depends on the power the fan needs) but there's something there.

2. The heat from the heater comes from the engine block, which cools the engine. On cold days (<15 F) this can have a huge impact on the engine's temperature and will often cool the engine well below it's most efficient operating temperature.
I don't see anything to support that.

And if it's a trade-off where more "impulsive" comments are deleted, then I prefer that to subjecting female respondents to constant come-ons from pubescent, sad human beings.

I think it's clear what Emmy Rossum prefers.
Someone ask him if it is true he thinks church is a waste of time (said this in an interview in the past I think).
I think it should be common knowledge among anyone reviewing an electric car that battery performance degrades in cold weather.
That's good, so it's basically "stop a bit, have a cup of coffee while your car charges"? Still not compared to gasoline, but, hey, viable electric cars!
If you are willing to give up range scans and constrain yourself to fitting all keys in memory there is a lot you can do. See SILT (www.cs.cmu.edu/~dga/papers/silt-sosp2011.pdf) and Bitcask (downloads.basho.com/papers/bitcask-intro.pdf).

Since this is a cache I really dig skipping any kind of cleanup/compaction step for deleted/expired keys.

I played around with a similar thing except as a K/V store and the performance and density is pretty amazing. With a 64 byte key and 1.5k value (compressed from 2k) I was getting 85k inserts/sec and several hundred thousands reads/sec with a quad-core Sandy Bridge i5 and a 128 gigabyte Crucial M4 on SATAII.
The fact that someone bought him Reddit Gold is pretty hilarious.
The author "had" to go heat off because he neglected to charge his vehicle. If you don't put gas into your conventional car it will also pose a safety concern in the winter.
True that. However, that would be a bit of a stretch. A more likely outcome is great coverage in short course for Tesla and another short tone-it a-couple-of-notches-down by NYTimes on the third page.

Unless of course there is legal entanglement.
that sounds great! let's connect over email and get this started? mayank.ot@gmail.com
It was a non sequitur, and a straw man - you said that python was 5 times slower than C at best and 30-50 times slower than C at worst on some benchmarks.

dnu pointed out that the benchmarks did not represent real-world Python code, since real-world code uses C libraries for performance-intensive stuff.

You responded by saying that programs that are 90% C and 10% Python are unrealistic.

Nobody ever suggested using programs that were 90% C and 10% Python, or said that that kind of usage was common. That didn't follow what dnu said at all. You weren't "reiterating" anything - you never said anything about "your uses", coldtea did, much farther up the thread. (If you're coldtea, then I understand your point, but if that's the case, you should have made that clear, as it vastly changes the context of what you were saying). You just brought up some benchmarks, which are not representative of how Python is used in the real world.

I see how you could have intended to imply that this was "your uses" by saying that coldtea must have unusual uses if he got go/2 performance out of Python, but this was hardly clear, if it is the case. Regardless, you totally misrepresented dnu's point.

As for your arguments against my points, the 80/20 rule, while obviously impossible to definitively prove, has far more authoritative supporters than it does detractors. If you haven't experienced that being the case, then that's good and well for you, but the experience of many others suggests that it usually is (in fact, it's usually stated as being closer to 90/10 than 80/20).

Your Django argument falls flat if you look at it more closely. Sure, Django might introduce some slowness, but the vast majority of web performance is in the networking and database layers, not the application layer. Your choice of language has little to no bearing on the networking aspect of things, but what do you think the database drivers are written in? C, or an equivalent. 10% of the code that has 90% of the performance impact - sound familiar? And you interact with database drivers most of the time exactly how I said - by using a Python library that wraps around a C library to run the database.

>>Quit with the straw man arguments - they add nothing to the discussion.
>Neither do unwarranted accusations of straw man arguments.

I apologize if I come across as insulting - it is not my intention. My phrasing in the grandparent comment was overly antagonistic, and I'm about to edit it to fix that. But my accusations of straw man arguments were correct.
Given NYC's sky-high rent, I wonder what would happen to the real estate market if these apartments were occupied by full-time residents. It seems grossly inefficient to have an apartment sitting empty for that long, no matter how much money you have. I guess there aren't too many good options, since airbnb-style renting is probably a) illegal and b) frowned upon by the building. If I were these people, I'd just treat the apartment as an investment property and stay in a really nice hotel when I was in town.
I used to take for granted that what I read in the NYT and learned from other highly regarded sources was factual and thoughtful. Then I read an articles about a subject I knew really, really well and the reporter got it completely wrong. Then it happened again and again. This made me worry about the quality of the information on subjects I don't know about.

I began to realize that journalists are not experts in all things or sometimes even one thing. Instead they are usually simply good writers operating under tight deadlines. And their goal is to write pieces that attract the attention of readers not simply provide accurate information. Lastly they are humans who make mistakes and have biases.

Take everything you read with a grain of salt. Think about how likely it is to be correct and not sensationalized or biased in some way. Check with others sources before you add what you read to your knowledge. The most dangerous thing is to think you know something that is either not known or wrong.
I hope this doesn't come across as pretentious, because I don't mean it that way.

But honestly, I don't take Hacker News seriously enough for it to bother me. I use it to build connections in the community, keep up to date on tech and news matters, and post things from time to time.

It's not as though I need my posts to hit the front page. I post intellectual curiosities and some of my more interesting blog posts around the internet, but I couldn't care less if a small but powerful "1%" holds voting power on Hacker News.
No, it's pretty sane. I work at a well-known NAS storage-appliance vendor and we're doing something quite similar in-kernel as a caching layer for our filesystem.
The charge will go down if it's cold out.
I like Tesla, and wish them really well, but it's TOP GEAR... I love Top Gear, but to expect any sort of honest, unbiased, and completely factual review from them is madness in the first place. That's really what makes the show so great is that it is nothing but jokes. The only thing in it though, is that there's a little bit of truth behind every funny joke...
Bill Gates Does An AMA On Reddit - Promotes Robots, Speech & More
Yes. It's not a direct comparison, but you don't see motoring journalists complaining about running out of petrol. "I only though I had to put $5 in... and it told me it was no longer empty... why did I run out 100miles down the road?"
Bolth. Bolth? Bolth.

It's different because when you realize your mistake with a gasoline engine, as long as you aren't driving in eastern Utah or some similar remote location, you can easily stop at any one of thousands of convenient gas stations to correct your error. Perhaps that will be true someday for Tesla, but it isn't today.
Hack of The Sexes
Funny idea! :) What about opening the Amazon page to target=_blank so that a new browser window/tab opens (instead of taking users away from your site)?

Also: Sign up for affiliate compensation on other Amazon markets (DE, UK, et a.). Use geolocation to target your visitors to the appropriate Amazon locale.
My impression is that Bloomberg has consciously chosen the strategy of encouraging second home ownership in Manhattan as an attempt to decouple New Yorks service and consumer economy from the financial services sector.

This trades off the progressive goals like affordable housing against providing a baseline of consumption activity to sustain NYC's tax base and its service workers.
I just finished reading the entire AMA.

If there's anyone who doesn't want to dig deep into the comments, here's a cool thing:

Bill Gates intends to eradicate Polio within the next six years and then eradicate Malaria within his lifetime.

Kudos, Bill.
It also shouldn't be in websites. This would make an awesome browser plug-in, which would also let you calibrate it (as mentioned by someone else) to be the "right size" for your vision.

I think a U-shaped curve could also be good: big text when you're far away, small text when you're at normal viewing distances, and zoom further [esp for full-page zoom] when you lean in very close.
Again? We need a single website alerting RoR devs about vulnerabilities.

I shouldn't have to found out about these things on HackerNews.

Someone build this website for us RoR devs, pretty please? (ps. use PHP - heh)
Have you met a journalist?

Yes, many times.

Where on earth do you get that generalization from?

See above.

Election reporting isn't comparable to the scenario in this story, because there are literally more reporters than there are subjects being reported upon. In my experience journalists play fast and loose with the facts when there is a low likelihood that someone will call them on it. That's why the previous NYT scandals have involved remote correspondents (Blair) and/or cases where the journalists are serving as lapdogs for powerful political interests (Miller).

If this NYT reporter indeed misrepresented the facts of his test drive, then he's just an idiot, plain and simple. He either knew or should have suspected that the car was logging his every move, and that an adverse review would be challenged strongly by the company.
Since smallpox I've heard of several diseases removed, but no talk about saving a few vials. Is this still done?
I think some sites have a bonus point degrader applied to them, so they age off faster. Prevents what may otherwise be popular sites from dominating the front page.
When I said "insane", I meant more "this is not something you would expect or that is immediately obvious". My phrasing wasn't the finest.
Hope you're not using default model binder, because M$ still allows for you to hang yourself with mass assignment attacks. Something they have yet to learn. Hope you're not running MVC 1 or MVC 2, you're still open to redirection attacks.

FLUID Demo: WebGL Particle Effects
I actually like the customize interface. That's not to say it couldn't be better. Something about it is very..... ugly. I think native widgets would go a long way to making it look like someone other than a programmer designed it. That being said, it fits the Emacs cross platform philosophy and it's a uniform way to look at settings, change them and get help on them and save them in your .emacs.

At some point I went and changed all my random "setq"s in my .emacs (built up over 10 or so years) to the equivalent customize versions and as a result was able to speed up my Emacs boot time by a significant amount (like 8ish seconds down to 2ish). The nice thing about customized variables is that you don't have to load in a mode to set it's variables (loading a bunch of modes during boot was what the slow part was).
Well obviously we can solve that by detecting how far the user is from the camera and increasing the "root size" as they get closer. /s

Professional, of course.

I also blog occasionally, and fact check my stuff. But if you're going to make money by the ad impression, you have a very specific set of incentives. Care and integrity are not high on the list.
We've been using lechat for the last few weeks and we are very happy with it. The UI is simple and clean. Fast history search is the killer feature for us. A number of nice UI details really show that this chat was developed by developers for developers.

I think it depends a lot on your particular configuration, since json is only an indirect dependency in rails (i.e. it's not part of rails's gemspec). It's clear that it won't get updated for everyone, which is why this warning (to make sure json gets updated and possibly add the dependency if needed) has gone out on the rails security mailing list.
hmm... i personally need to understand the why before i have any ability to remember/understand/apply/execute the how.

i guess that's the difference between people that inherited knowledge (without any need of it) instead of having to arrive at it (because they were feeding themselves and their kids with it).

that kind of explains why, of the over 200 interviews i've conducted, some of the college educated "programmers" i came across seemed knowledgeable; until i made them write code that is.

thanks for solving that conundrum.

That is funny; unfortunately, it's exactly the opposite problem I have with Amazon.
> One big difference is that heat (and thus warm air) is a by-product of internal combustion, so a typical car's heater will ALWAYS work, which turns out to be critical for survival in certain climates.

It'll work as long as you have gas, just as the Tesla's will work as long as you have battery.
I am missing the part where I am morally impelled to subsidize poor decision making. This applies specifically to the flood plain example - though there are some corollaries to health care; eg. people eat bad food and smoke etc... which leads to increased costs.

The post states that flood plain knowledge is high - and the data is easily available. So why should I help someone if they are knowingly taking a risk? The point of taking a risk after a risk-benefit assessment is that there is a payoff that would be greater with the risk than without it. If you shift the cost of the risk away from the principal agent, then there is no impetus to optimize your decision.

So again, why should I absorb your risk if significant and verifiable information is available?
Isn't it using electricity that is already being generated by the alternator whether the heat is on or off?
And if Elon fails to actually prove this reporter lied/fabricated the review and just waffles, the NYT is going to skewer Tesla in their response and this story will get much more legs than if they had just ignored the review.
Did someone say Teamviewer, no seriously. Just try it.
Sometimes I regret to have taken the red pill. Now I see all those pattern everywhere and my commitment to write code true to my learnings make me work the extra hours.
I've got to ask: could you share what app or at least industry that app is in? I've never seen 134,000 test cases before for a web app, and 220,000 assertions to boot. What's the ratio of test cases to code? It sounds like a record to me!
So add on about 12% onto a time estimate to account for the extra charging time. I'm estimating about 2.5 hours for 150 miles which isn't unreasonable for freeway driving.
So in summary, while Top Gear was correct in saying it had a 55 mile range with the way they were driving it on their race track, they falsely claimed that the car ran out of charge and had to be pushed into a garage. Instead they just turned off the car and pushed it into a garage.

But the judge said that this is the kind of thing you expect from Top Gear as an entertainment show and it was ok to say it ran out of charge?
Using a language that supports an interactive development library might speed up the process for you.

I use Clojure, and like Incanter for this kind of work. I also use Datomic as my data store, when I can, which makes it quite easy to perform ad-hoc queries.

Of course, the fact that your data is too large to effectively fit in memory means that, whatever you're graphing, you're going to have to aggregate it a bit first before you can visualize it. That's really the hardest part of what you asking, and how you do that efficiently depends entirely on what your query is and what kind of data store you're using.

I'm not aware of any off-the-shelf software that does what you're talking about, unless it fits into an OLAP-type schema (http://en.wikipedia.org/wiki/OLAP_cube) for which there are several products available.
Licentious - License your GitHub repository in seconds
So for a 1000 mile trip, that is going to be about 6 charging stops.

3 hours added to the trip - and probably more like 4 hours when you consider that the Supercharger stations are not going to be located right on the main roadways all the time.

A 1000 mile trip in a gas vehicle would require 3, maybe 4 fuel ups. I've timed my fill-ups many times, 7 minutes from off the road to back on (assuming an en-route gas station) is about the average. So, figure 28 minutes lost to fueling, vs. 4 hours. The Tesla will take at least 3.5 hours longer to make the same trip.

1000 miles at an average of 50 mph (seems low, but I've driven 720 mile trips from NH to MI many times) is 20 hours if you drive straight through. 20.5 hours with gas, 24 hours with Superchargers.

I love the Tesla cars, I've seriously considered the Model S, but I don't see how (for me) it is really a viable long-distance driver yet. Yes, you have a better chance of not getting stranded vs. maybe a Nissan Leaf, but it's a suboptimal alternative to gasoline still.
>other than the larger amount of time it takes to charge a Tesla

That's exactly what they said. You can (slowly) charge a Tesla at any electrical outlet.
I'm not kidding, are you?

You think that if the thought of being burned over 90% of their body isn't stopping someone from smoking in bed... that the thought a big hospital bill will do the trick?
