skysight-inc/HackerNews huggingface dataset:
Overall a good article with some insightful points. One thing strikes me as a bit off, though. The recommendation for one or two cores per GPU seems not quite right. Examining only the CPU<->GPU performance, this might be reasonable. Like the author mentions, you can use the other core to prep the next mini-batch and all those sorts of tasks. However, training the model is only one part of the system, and I tend to value the overall performance of the system more than any one facet.

For example, despite training on GPUs being very computationally intensive, I find one of the most onerous tasks to be the custom data prep/transformation/augmentation pipeline. Because these types of things are usually pretty application specific, there often isn't a ready-made toolkit that does all the heavy lifting for you (unlike the GPU training, which has Torch, Caffe, pylearn, cuda-convnet, lasagne, cxxnet...), so you end up having to roll it yourself. Often you have to run this code often, and with large data that isn't trivial. Usually you won't invest--at least, I don't--in doing custom CUDA code for this type of thing, if it's even possible, so having lots of fast CPU cores is a win. I usually write multi-threaded routines for my processing steps and run them on 8-32 cores for huge gains. So my point is that "one or two cores per GPU" is a bit of a narrow recommendation.

The same applies if you want to do 'real time' data augmentation (this is hinted at later in the article) and/or if you want to deploy with CPU only. Sure you need the GPU to do the training in a reasonable amount of time, but once you've fit your model, it might not be worth it to deploy to GPU-enabled computers if all you're doing is forward passes.

PS: This is also a place where running on EC2 can be a win. Maybe it's more economical to build a workstation, but once you're in the cloud you can spin up a few 32 core boxes to run your preprocessing really quickly, shut them down and spin up some GPU instances for training, then shut those down and spin up some mid-tier boxes to run the models through a bunch of data without breaking the bank. All in 'one place'.
How do you ensure people won't be required to still fly out for 3 days of interviews? How do you prevent this from being just another filter before the "real" interview begins?
Whoa thanks for brining this to attention. I have this as well and didn't even think about it! I would need to carry an adapter with my YubiKey.
Wasn't FaceTime supposed to be an open-sourced framework/protocol?
We're not looking for pentesters.
512GB? Not yet. 256GB? Yes. I'm not sure why you are asking though. Do you think they aren't going to provide it for some reason?

You might want to read that whole review if you haven't already. They found that the XPs 13 had excellent battery life, to the point that they tested it and it was exactly what was advertised. That is, for the low-end screen (1080p) they got over 15 hours of light usage. Dell provides battery life estimates for different configurations (visible in the review[1]), so it's not inconceivable that i7 light usage might get over 11 hours as Dell claims.

To visit the area surrounding Fukushima you need a rad-protected hazmat suit, because apparently the contamination is so bad as to be deemed unsafe for unprotected humans.

Yet if you pulled out a Geiger counter outside of the plant itself, the reading you'd get is less than what you'd see in a typical hot springs bath, the national leisure in Japan.

To be sure there is a difference between relaxing in a high-rad bath for an hour or two, now and then, and living in one 24/7. The latter probably wouldn't be very healthy, either. But our knee-jerk response to anything involving the word "radiation" some times does more damage (economic, etc.) than the radiation itself.
No.

I don't wear a watch now, but I get lots of phone calls. I was interested in the phone via watch concept, but really I think it'll be a few years before that's bulletproof. I noticed a delay in the demo, similar to taking phone calls from the iPhone on the Mac using continuity.
Agree about bugginess of Software. It seems that Apple shifted focus from overall flawlessness and coherence of UX to craftsmanship and advanced technological processes in hardware. And since we started to see all those weird "Connect phone to iTunes to receive push notifications" popups, etc. If we will have products, whose surface was polished by zirconium particles but that are always buggy and unreliable, it will be not the Apple we all loved. Not "advanced features" but "lack of annoyances and irritation" is what made Apple what it is now, in my opinion.
I wonder if Apple will migrate over to USB-C even on iPhones and iPads...
This is where I stand as well. I have the 2011 MacBook Air 13" and I just wanted a version of my current computer with a retina screen (plus the latest processor). I don't want anything smaller/lighter and certainly nothing less powerful.

With this update, we effectively have three choices:

1) Low powered, nice screen. (MB)
2) Medium powered, regular screen. (MBA)
3) High powered, nice screen. (MBP)

What I want is 2') Medium powered, nice screen.
Here's the developer overview:

It appears to mostly be an iOS UI toolkit of sorts for easing the creation of individual apps to collect research data. The hard work must still be done by each individual research project.
Why you shouldn’t try to host your own email and how you can
Of course. But you still hire more skilled people over less skilled people, and if free time contributes to skill it's not necessarily unfair.

In fact, I think a quality CTF could level the playing field, since each candidate could be judged on their relative abilities (how far they can progress through a game that adapts to their prior knowledge). Moreover, one could offset the time commitment by paying candidates to do the CTF. Certainly paying people a decent wage for 6 hours is worth the benefit of hiring a better long-term candidate. There are all kinds of ways to fix the problem.
I think that anyone motivated to research and work on these problems, will likely be a decent hire in most organisations.

Having done other CTFs and puzzles like Matsano / Stripe's, I have found the research part is quite enjoyable. I have little to no knowledge of crypto but researching and solving some of the Matsano challenges was extremely rewarding.

With that said I found the information is pretty thinly spread and it is often hard to find relevant information to the problem domain, particularly with regards to crypto, so I hope they include good starting points for problem research.
I think guests should graciously work with whatever hosts provide, as long as it works.
Yeah, who on earth uses headphones with a laptop. Crazy.
I think it's pretty one dimensional to call Facebook's VR acquisitions purely motivated by having a pile of cash laying around.

There are plenty of smart people who see VR finally coming around to be the disruptive technology that it was thought to be 25 years ago.
Yes and yet I am still lugging adaptors
- DP to VGA
- DP to HDMI
- DP to DVI
Because I never know what I'll have when I present and you know what, I nearly always have to revert back to VGA, its not like HDMI is new !

I have a nice integrated laptop but I have all these parts around in my bag that I sometimes lose or forget connected to a projector somewhere. What may have seem like a simpler solution really wasn't in the end.
Sorry, I think I'm a bit of a cynic and a bit burned out. There seems to be at least an expectation in the tech industry of having to maintain certain after hours activities to make one self marketable. Personally having a 50+ hour a week day job + side projects + studying + leveling up in order to find new employment is exhausting .... I'm just concerned adding another implied responsibility to a candidates plate seems overwhelming.

But, if someone loves to play CTFs and is seeking employment than its a great match. Me personally I'm a build things I want to see in the world and the job will come ... kind of person.
While I'm very happy to see attempts to get rid of the interview and move towards a work-sample test, this comment represents the whole sense of unease I have at this.

There is, of course, releveant XKCD: http://xkcd.com/927/

I can say that I have hopes that if anyone can stop what you fear from happening it's these people.

I think it's primarily written to a different audience than yourself, then. I mean that in the best of ways. As an infosec sort, it came across pretty clearly what they intended. I think it's just a culture difference between information security, and the rest of IT.
Starfighter is not a security company. We're going to test for a wide range of skill sets. These may include web app security but will not be limited to that.

You can reasonably assume "What skills does the market want to hire for?" is a good proxy for what we'll be assessing for. I love security, but that's 0.01% of the software market. We have... grander ambitions.

There are various issues with djb's counterargument, the most striking one is that the argument may hold water in the US, but it's certainly not applicable to the EU [1] or other parts of the world while a real license is. If you want to share your work, give it a license so that people know under which terms they can use it.

[1] the EU directive cited requires you to lawfully acquire the program and does not cover redistribution.

What models are you talking about? Shipping with no mechanism to do this is in violation of the Windows hardware certification requirements, and vendors falsely claiming compliance are both falsely advertising and breaching their contracts with Microsoft, so it's a pretty big deal for them to do so.

> And I'd say you should stick to low level coding and not comment on the economics of competition and the contents of the US vs. Microsoft dockets... unless you are an antitrust lawyer, an economist AND a kernel hacker?

You are an antitrust lawyer and an economist?

> So a single switch is monstrously expensive unless Google mandates it, in which case it's not a problem.

In the Windows world, if Microsoft's demands become too extreme you can ignore Microsoft, undercut your competitors and ship Windows anyway. In the ChromeOS world, you can't.

> Funny. I tried installing (the latest release of) Ubuntu the other day and got nothing but a cryptic error message because secure boot was turned off.

If Secure Boot is turned off then your inability to boot Ubuntu has nothing to do with Secure Boot.
You're quite right that a CTF is not the same as open source projects... and I thought the point of this was exactly that. People who contribute to open source projects prove they have a certain set of skills. What if you need people with a different set? What if instead of being able to learn a large codebase, it is more important that they are able to look at a problem and design an algorithm to solve it in the first place? Rarely in an open source project will you be going in and radically changing the fundamentals.
The fuel process used by nearly every reactor in existence is used specifically because it can provide weapons-grade material. It is not the reaction chain you would choose if you were merely interested in generating electricity.

Besides the CANDU reactor mentioned by the sibling comment, there is also thorium reactors, which react an element far more abundant than Uranium, and doesn't result in weapons grade products.
Do you still do this? I'm currently going back to school for a degree in CS and was thinking about doing something like this for my Calculus/Stats class... maybe with Highcharts or even D3.

Do you have any recommendations if I take this approach?
I think the logic is that this particular chassis is constant, and we are to assume that battery technology will only get better.

So while the laptop may be underpowered/under ratio _today_, it won't be in its next incarnation, i.e. same chassis but better batteries.

So it's more of a bet/investment/concept car. This first gen isn't where the ratio is satisfied. It's v2 and onwards.

It's worth noting that the Quad-HD screen only comes on the more expensive models, starting at $1299. The lower priced ones come with a 1080p screen.

That depth difference could feel pretty significant when the thing is razor thin.

Comparison article: http://www.theverge.com/2015/3/9/8177065/apple-macbook-specs...
You might want to talk about the diversity benefits of this approach. In particular, it would be attractive to lots of companies if you can make a credible case for this attracting traditionally hard-to-reach demographics, and then of course assessing them more fairly.
I don't have one yet, but there is a guy who left comments on Amazon who has good experience with Ubuntu:
http://www.amazon.com/review/R2UHFYMBSR02RT/ref=cm_srch_res_...

Amazon has temporarily inflated prices for this low-availability item. I'm waiting for NewEgg to get them back in stock.

Trackpad does seem to be one of the lowpoints of ux305fa. esp. if that's something that's important to you. I tend to adapt to trackpads and like whatever I use most.

I have a different Asus machine, the super-cheap X205, which I got for $180 at a Microsoft Store. It's plastic, but surprisingly well made. 2.2 lbs and fanless is great experience. Main problem is it's a pretty slow processor and has just 2 GB RAM, 32GB flash drive, basically tablet specs in a laptop form. I've extended it with 64GB microSDHC. I do find myself using more powerful machines at home (Lenovo X200 and X220) but even there I'm enjoying the X205 quite a bit.
Battery life is supposed to be excellent[1]. TL;DR 15+ hours of light usage for the 1080p screen (tested and confirmed by Anandtech), supposedly 11+ hours light usage for the QHD+ screen with an i7.

There are other companies that have tried to be the one-stop-shop for job hunting. It would suck if I worked on my Starfighter rep[1] and then I see a job I want but they want to use my HackerRank rep or StackOverflow rep or whatever elese instead.

This game is not for people who like you (or me) don't have much interest in assembly, systems programming or pen testing. (This group includes, by the way, a large group of very talented programmers who've shipped most of the software the world uses).

It is troubling that the language they use on the site implies that systems and security programming is what all programmers aspire to do, but that's just an unfortunate bias on the part of the authors. Personally, I think they'd do well to change it, but perhaps that's exactly how they feel and exactly the kind of messaging they need to attract the right people.
"(a) For the same reasons you'd noodle with any other game"

I play games for fun and to relax.

"(b) For similar reasons to the ones that make you noodle with a programming language you doubt you'll ever use in production"

On your website, it says that these will actually be real problems for real companies. I would think it's something I would see in production?

"(d) Because for some of the technologies/concepts we work with, our dumb game will be the easiest way to get your hands dirty with them."

Isn't this what open source is all about? Pretty much every job I've ever had involved technologies I could just download or install myself and throw on a Linux box/VM.

I suppose it could involve proprietary technology that I would never see in the wild, but if this is the case, I don't think I could get enough experience with it on your game to prove to a company that I know enough to get a job.
It really depends on the scope of your project, if you are writing a library (for example), GPL is a bad choice because you limit your audience to strictly GPL grounds (unless you really want that).

Many libraries have changed their licenses from GPL/LGPL to MIT because GPL/LGPL have proved to be troublesome for specific platforms (ex. Mobile Devices).

There are many political views involved, but the reality is that users are the ones who suffer the consequences.
About the security content of iOS 8.2
There's already apps that do that, some targeted to specific conditions.
From the SO post, "it is using IOSurface to sneak past sandbox restrictions to have raw screen access."

From iOS 8.2 security updates:

Impact: A malicious application may be able to
execute arbitrary code with system privileges

Description: A type confusion issue existed in IOSurface's
handling of serialized objects. The issue was addressed
through additional type checking.

CVE-2015-1061 : Ian Beer of Google Project Zero

If any app can escape (by dynamic linking to a private API) sandbox restrictions on screen recording, can they escape other sandbox restrictions, e.g. key recording?
Yeah, it looks pretty. I'm way more interested in news about the 15" Macbook Pro. It really is the only developer laptop I'd consider at this point. Given the fresh reviews about the new Macbook and the trackpad update to the 13" model, I'm a little worried they're going to do something screwy with the 15" model. Haptic feedback? Do I want this? I think it would be rather frustrating to have wikipedia entries popping up when I'm trying to highlight my code.

Touch pressure is such an individual thing. I tend to pound on my keys and trackpad. It's the way I am. This Force click business (while reminding me of Force Push and Force Pull) seems very different from a binary "click" vs "no click." Even if you can adjust the sensitivity, it doesn't help when someone else has to use your laptop.
We wrote the Matasano Crypto Challenges.

Besides cryptography, what are some other programming problem domains you'd enjoy playing with? We're particularly interested in problem domains that are hard for ordinary programmers to pick up on a whim. We want to make it possible to seriously engage with interesting problems while in your couch with the Daily Show running in the background.
Well, no, If you publicly release the source code to your proprietary software, people can download it and tinker with it, so long as they don't distribute it whether it's modified or not.

Unreal Engine, for example, has its entire source available free of charge online, but it's proprietary software and you can't make changes or use it to make a game unless you obtain a license from Epic Games (which is now free of charge in many cases, but you still have to go through the process of getting it).
Reminds me of a local company who recruits employees exclusively by organizing coding contests: http://contest.catalysts.cc/en/

It works great for them, but I believe you attract a certain kind of developers with these contests; you attract people who enjoy puzzles, and people who enjoy measuring their abilities against others. It could be that those are the traits that make good employees; but I myself would never take part in such a competition.

Then again, I don't actually want to work for anyone else at all.
India, a police state ? You're kidding, right ?

It's government is supremely incompetant, but a evil police state, it is not. If anything, it is a functioning anarchy with a - largely - parasitic Government.
This is what you get in countries where good infrastructure isn't considered a communist conspiracy and where one of the major political parties is not overtly anti-infrastructure. France, Germany, etc. also have public transit in most places.

For people interested in typography: It seems like the Apple Watch UI font (San Francisco) replaced VAG Rounded as keyboard font. This is interesting because it would be the first time (AFAICT) that Apple uses the same font for keyboard and UI.

He raises a good point. I stopped reading NYT online regularly when I started spending more time reading HN. The fact is you have to pick your battles. And what you spend your time on.
