Now admittedly this is sampling bias, but I have never seen code written by a quant that could be put into production without being reworked by a software professional.

The skill sets are in some way exclusive of each other. Quants do lots of exploratory work. This involves tons of one-of experiments and throwing away things that don't work. They often frequently don't have the operational understanding of the way the systems they interact operate. Further, making stuff fast on a computer is a very, very particular skill. People that could do all of that are extremely rare (such that I've never met one).

Oh oh. Now you've done it. You spoke unfavorably about Google, my corporate parent. How dare you!

Google Brigade to the rescue!
This is something of a tangent, but this is kind of a cool visualization of what is sometimes called a "spinorial" object -- an object which can undergo a full rotation and yet not come back to its original state. Here the number of rotations necessary to restore the original state depends on the number of teeth on the gears.

A more classic spinorial object is a belt attached to, say, a book, or apparently your own arm holding up an oriented plate:

It's interesting that I don't hear these stories from the Android or Windows Phone ecosystems.

I think this might be a situation where Apple being first-mover has been a disadvantage to them; they started with a "sync to one single computer" design, and have been patching on that over and over to move into the new ecosystems. The other options in the market started with a "sync to cloud" design, so they had to solve issues of merging and collating data from multiple devices out of the starting gate.
Google can say that, but I and many others simply don't believe them.

Google is a business, and an advertising business at that. It's literally their job to try and make us believe what they say, regardless of the truth.
Top lists are saved historically every day for all 45 countries. Would be great to see what people can build with it!
Interesting. What do you use the data for? Why is it valuable to you? How do you estimate the site has thousands of subscribers?
I really like this which was linked from there: http://kumailht.com/gridforms/
Any serious operation dealing with the amount of media (images, videos, various editing files, etc) that Sony was is going to have very fat pipes. They probably moved upwards of a few TBs a day.
Now if you are a programmer, how do you get into the industry? You need to know stats, machine learning, and programming, really well.

My experience being a quant and being around quants is that, sadly, they don't get to use much machine learning. Some do, but it seems like 97-98% of the work is much more mundane.

Am I correct in perceiving that many hiring managers expect more in the way of interesting experience than they really need (or have to offer in the work that needs done)?
Here are some great books which are meant to be read (and have not been mentioned elsewhere in this thread, i.e. Axler and Pugh).

Thank you for the example of SQLite being used with Scribble. I was playing a little bit with the sqlite interface, but using it rather naively to pass queries and return values.

Not quite sure I have the Racket chops to implement something like a data.frame abstraction over an in-memory SQLite database (or even dplyr style query construction). Maybe a project for after I get off Hacker News and finish up a couple of articles that have needed finishing...
Yes I saw the brochure haha. Yes, of course, I get it's an outdated site. I wonder why it's still up right?

Costolo’s Latest Maneuver: Invade Your Phone and Track Every App You Install
It's just a culture filter. If they have data backing up their methods, that would be nice to see and compare to Google's hiring process that rejected puzzles and brain teasers. I personally don't think there's any correlation with brain teasers and programming ability though.
Trigger warning: passing the CAPTCHA on homakov's demo page (https://homakov.github.io/nocaptcha.html) registers an account (blog?) at wordpress.org.
The general formula is you have to nurture and build your own community. Quality over quantity. There are many examples of people aggregating and filtering content (http://iosdevweekly.com) to producing content (basically all sites from the smallest blog up to BuzzFeed). The metric if there is one is how engaged your community is. Do they open your regular cadence newsletter? Do your current readers forward your newsletters? You can game social media all you want and in the end the real thing is are you providing value to people in the community you are contributing to/part of. All those people who sell 2,000 books with a single email spent hundreds of hours growing their email list one by one. It is easy to write one blog post that goes viral. And to get them to come back and read what your write next - that is harder.

Grow your community, give back, deliver something unique that you can provide on a regular basis.

The reality is you don't own anything if you work for a company. But if you have 100 or 1000 mailing list opens - that is all yours.

The rhetorical question is do you want to make $12,000 a year or $120k/year. The catch hear is $120k is salaried and NOT geometrically scalable while the $12k refers to your own sales/ad revenue. That what you own and have built is scalable.

It is all about influence and/or providing what people want.
What We Should Learn from Fab and Aereo: Liquidity Matters
Absolutely. I think it is a very difficult problem to solve as companies grow larger and larger and rise to behemoth proportions all while trying to tackle something that is relatively new (the security concerns of today, as opposed to say the 80's,90's,2000's when Sony didn't have to be as competitive in the products that they offered) and typically expensive (for a company Sony's size) where funding for these things seem to be viewed in terms of $ now, instead of potential $ later.

I'm glad to say some states in the US are enacting similar laws, called "Good Samaritan" laws. In essence, the laws "shield a person who calls 911 from arrest and prosecution for drug use or possession, underage alcohol use and similar crimes."

According to this NY Times article (from 2013), 11 states and DC have passed such laws: http://www.nytimes.com/2013/04/29/opinion/calling-911-should...

Since you obviously don't know who Homakov is I can't take your post very seriously.

Homakov has exposed several serious security flaws at Facebook and Google before. I'm pretty sure Google is actively trying to headhunt him since he is one of the best in the web security field.
OP is asking whether Amazon offers public addresses that will respond to DNS requests for end users, such as 208.67.222.222 and 208.67.220.220 (OpenDNS).

To my knowledge, they do not - Route 53 is made for domain administrators to use as their nameservers instead of their domain registrar's.

I actually think the opposite.

The way it is built is just perfect to get used to automation of hands. You have the feeling right away that you can use "tab" and "space" to change/fill/move things in those.

Putting more fancy things and making it not "boring" is not an easy job and most of the time fails i think.

"make users feel more at home" will lead users to be focusing less time on the actual task and more time on the tool, isn't it ?

Apart from what this framework does (didn't have time to play much), I congratulate the UX guys on this project for choosing this kind of design and behaviour.

They could have totally another idea maybe for going this path but i love it.
The work still has to be done manually in those cases, though, whether they type it themselves or rent use of a captcha farm.

Half of the post is about how the new technique is vulnerable to clickjacking.
A contest to build high-flying airships? NASA's thinking about it
Julia has macros denoted by an at-sign (e.g. @inline) to make clear that something special is going on. Understanding how to write effective macros takes some work - perhaps more than Lisp; I can't fully say, myself - because expression representation is less apparent to the casual user. This, combined with an emphasis on "don't use macros when a function will do", seems to have lead to fairly judicious use of macros in most of the code I have seen.

Good tooling can also help with the locality problem. For example, by showing macro expansions in-place when possible (and desired).
I have a hypothesis. And I think it applies to your comparison with religion as well. It has nothing to do with the typical "sheeple" argument. Or at least, that's only half of it. It's a matter of "forces", equal and opposite. While Apple does seem to attract a lot of folks coming out of the woodwork to defend it, I would say it also attracts a disproportionate amount of hate as well.

You'll see this happen pretty much anywhere. Politics? Far right wing nutjobs come out of the woodwork, angering far left nutjobs who come out of the woodwork to counteract the former. Ditto with military forces. Rebels/terrorists come out of the woodwork, suddenly extreme force (e.g. aerial bombardment, rendition, etc) is A-OK to cancel them out. Religious fanatics come out of the woodwork, and then the atheist fanatics come out of the woodwork.

The middle pretty much ignores the fringes until the battle actually affects them. Then everyone's coming out of the woodwork.

Yes I think you are Michael. Especially for quant jobs 2 and 3 that I enumerated.

The only reason I listed machine learning is that it is the trogan horse that gets programmers to learning stats. I can't over emphasize enough just how much you need to know stats. half of trading is knowing stats as all good traders trade only when they have the advantage. 100% upside for 10% downside is a good rule of thumb.

I mentioned the deep dive into the machine learning techniques as unfortunately most of the programmers I meet who call themselves data scientists, just aren't very good at stats. I'll ask them what methods they use and they'll tell me the library they used.

Unfortunately most interviews go like this:

me: I see you did some K-means clustering, tell me about it.

them: Well, we used R to cluster related books into groups.

me: how did you choose the inital partition

them: blank stare, um the library does that.

me: yes, well I mean did you use Forgy or Random Partition

them: I don't know what those are. That's just random trivia that I would look up when working. Do you find asking random trivia helps you hire people:

me:...So do you have any questions for me?

Hedge funds have lots of mundane programming jobs. Most are back office stitching together WPF and accounting systems. Even at the HFT firms I've seen only a small portion of the programmers actually do anything on the main trading system.

I'd love to hear about your Jane Street experience here:)

Like most things the closer you are to the money the more you'll make and the more exciting your job will be:)

Most quant jobs that I've seen were very mundane, category 3 is most of the quant jobs. Though most will tell you that they are in category 1 :)
AppGyver dev here – I hear you, the build service wait times are a real pain, especially when you are debugging a custom plugin and need to iterate quickly.

However, local builds are on the pipeline – can't give a date yet, but you'll definitely be able to build your AppGyver apps with Xcode/Android Studio. (We'll provide the AppGyver Wrapper code as a library you can include in your project.)
Interesting. I've run a somewhat successful aggregation website in the past, and found that I hit significant scaling problems.

Can you provide a few more examples of aggregation / filtering services that have achieved reasonably high profitability? Always interesting to see what other people do that I don't!
If you are looking for calculus one resources, Jim Fowler's Calculus One Coursera course is great, IMHO. I watched the videos at 2x speed (I found he speaks very slow, which can be great at times) and was able to complete it in a couple of weeks. The best part was that it didn't seem like he tried to "dumb it down". I would also recommend reading one of the many books others have suggested while taking the course - I've found that I learn much better when I hear topics explained in different ways and from different perspectives. Best of luck!

I guess it’d be good if the website mentions a bit more what are the differences with and advantages over Bootstrap. I’ve never used Bootstrap for public facing app because I find its look too bland, but I love it for internal apps. IMHO it doesn’t exaggerate at all on the level of ‘glitz’ (one of the arguments of the OP against contemporary frameworks).
I actually thought they were great - I mean, I wouldn't trust their product, but all I've experienced multiple times there were people who whisper the name of the drug they're selling in your ear while walking past you in the opposite direction, never had anyone trying to convince me to buy. The only time I've even had to say a word back to them was when a friend and I were curious what the street price was so stopped one who offered and said sorry we're not buying, but would you mind telling us the prices, and he did and then went off cheerfully.
I believe he's talking about Diablo 2 (the timeframe works, and the game is notorious for duping), in which Blizzard provides shady third party companies with items, which are then sold to users.
Its pretty telling that after he dismisses the need for maps because, apparently, normal users never drive to unfamiliar places, he dismisses the need for flight updates in part because normal users drive to vacations (and when they do fly, apparently, their planes are never delayed.)

>>People love not to think

O_O

judging by the comment you wrote right after that, I would assume you are one of the people who likes not to think.

They are making people click checkboxes and deviating from the old model of recognition. Your comment makes no sense.
The controls became unresponsive a few times while I was viewing the panorama mode. I'm not complaining, as this is probably more a result of my browser than of the site.

I do have a minor constructive criticism however. When in panorama mode, there's a lot of up-down-up-down action, at least on parts of the Zugspitze. I'm guessing the camera is just tracing the contours of the mountains, but on rough terrain, it's a bit motion-sickness-inducing. A bit of smoothing of the camera's path would go a long way. I think a steadicam shot from a helicopter is everyone's real-world point of reference for something like this. Mimicing that might go a long way.

Anyway, amazing work. I hope to see some North American mountains in future releases.
Head of modelling risk for RBS. Maybe some of it was derivatives. Some of it should have been modelling the cost of borrowing money on wholesale markets. The RBS strategy was leverage to the hilt, borrow short, lend long. Lunacy.
> Do you really think that they would go ahead and implement a such system without rigorous testing of effectiveness? I am sure that they tested it extensively with users, AND with bots, and decided that it is better than the current system, and ONLY then deployed it.

I think the gap between the marketing material for nocaptcha (a simplified website, a youtube video with animations) and the seemingly lacking actual implementation is why this blog post was relevant for me.

Like other tech people around here, I was hyped up by the "smarts" of a system that uses cursor detection etc. to silently validate that I am a human. This blog post seems to indicate that the validation is a much simpler issue of previously passed tests and the amount of data that Google has associated with the user.

I'm filled with envy and rage over the fact I'm not good enough at math for this. I barely did above average in my grad level math courses in college (studied aerospace engineering). I worked my ass off; I should have breezed through it if I had the ability to be a quant.

CS department websites in general seem to be so, so very bad. Does anyone have an example of one that is good?
This is great - I've wanted something like this in a while. Piste Maps are a massive distortion of reality to the extent that you sometimes aren't sure which direction you're meant to go down the run. Or at least I'm not, I find them very confusing. A proper 3D representation is much easier.

What would be great is this data available in a mobile app, with no internet connection required (because even though 3G coverage is good, for a lot of Europeans when you're skiing you're usually on holiday and so roaming). Then I might actually be able to find my way around.

Where does the data come from? Is it manually entered from the Piste Map?
>So my guess would be they analyze users behaviour on the page where captcha is located, things like mouse movements

If they can track mouse movements why in incognito mode i'm not a human for them anymore? I was expecting same but from what I see it's just a whitelist. And it's OK. Problem is, which you probably didn't care to read, is it's vulnerable to simple clickjacking which opens another weakness - i can use your click on my page to get your reCAPTCHA token and feed it to my spam bot.

I'm actually happy with No CAPTCHA, because it's making progress. But it's not good enough (see the rest of comments, it could be a background AJAX request instead).
That was my read on this too. Consider how an iPod reacts (or used to, I haven't used one in a long time now) when you plug it into an iTunes instance that isn't the one you originally synced it with - it asks if you want to flatten everything and replace it with the contents of the connected library.

Thanks for the feedback on the camera movement, there is some smoothing, but it is on a much smaller scale. I originally did have a helicopter steady-cam style camera for the panorama, but switched to following the terrain to make for more dramatic camera movements. But if it makes people sick, I guess this is a bit of an own goal...

US resorts are coming, just need to process the data.
The google's blogpost says that 98 something percent of old text could be deciphered by AI. My point is, regardless of vulnerabilities of the new system, I am certain that it is more effective than the old alternative. They would have tested it.
I love this site as simply an index of interesting Lego sets. But on a few of the items I spot-checked marked OOS, they are in-stock at Amazon. Impressive amount of work for a nice parent-friendly niche problem though.
I feel like you should invert the color scheme. If something is out of stock I don't really need to be drawn to that. If something is in stock, though, I can buy it.

This site reminded me again of how expensive Legos are though... really makes me feel like a spoiled rich kid for having had so many way back.

To any readers. I highly suggest you try DuckDuckGo, especially for tech related/documentation searches.

The !{language} searches are incredibly powerful. Taking you to the language's documentation repo, and displaying results only there. Which I find hugely help for learning new languages.

I've switched over completely for my day to day searches. Google offers next to nothing I can't get with DuckDuckGo.

On a side note, Route 53 doesn't support DNSSEC unfortunately. Might be part of the reason that Amazon.com uses Dyn and UltraDNS instead?
