Yes, that the weirdest UX feature of HN. In the age of mobile, having two 10px high buttons with opposite meaning separated by 5pixel is absurd.
There's definitely a benefit to developers. Hoomi provides an alternative to social login as well as an easy way to get single sign-on across their suites of applications. Furthermore, developers can adopt Hoomi rather than adding their own email/password-based login mechanism and avoid having to build screens for login, signup, email/phone verification, password reset, account management, etc. Essentially, developers can treat Hoomi as their login-as-a-service provider.

The Problem with Measuring Experience
Is it just me that worries about a race to the bottom with brain hacking? Assume some combination of nootropics/transcranial stimulation/etc gives you a short-term edge for unknown (or known) long term risk.

If you're a profit-maximizing employer, would you rather hire the person who performs better today, or the person who is looking out for their own long-term safety? Or if you're a startup founder competing against a bunch of doped up super-brains, how strong must the incentive be to join the dark side?

I see similarities with professional sports, where athletic associations are always playing Whac-A-Mole with performance enhancing drugs, and top earning athletes routinely get chastised for doping. Should we expect outcomes in knowledge work to be different if brain hacking proves as effective?

One of the main problems on tech is the "middle ground", covering that special place after rookie and before being an expert...
It's incredibly difficult to effectively communicate about this, and I think is why people get frustrated or think they are not good. Because they are not on the "expert level" on something (knowing every single detail), but the simple hello world small apps are too easy and doesn't feel awesome any more...
The area in between is not visible, so it feels a little like not making progress sometimes... Though is arguably the most interesting/common one.

Piracetam is one of the most popular ones, it's not hard to find, and it works for most people, or not. The most common side effect is muscle twitches or headaches. Headaches are caused by a reduction of the amount of choline, and eating eggs or taking a choline supplement makes the headache go away. Generally the twitches are not severe and don't affect voluntary movements. The side effects subside upon stopping. I'd say it's a completely different effect than caffeine, as it allows me to concentrate for extended periods and have instant recall. If it is a placebo effect, then whatever it is, it works. Placebo effect means there is an effect because there is expected to be one, so in any case it's useful. Piracetam's effects on the body are well documented, since it's been in use for about 35 years now. That said, I don't think this gives you any more rest, nor does taking it make it so you can't sleep. In fact, if I take too much I feel sleepy almost immediately and wake up feeling pretty good. In any case, these people taking nootropics are the new normal.

Your invocation of slavery to generate sympathy for your political goals is disgusting.
It was jaw dropping as-is, but when they finally do stick a landing I imagine the engineers will be running around like little kids screaming with the pure joy and exhilaration of it all. I hope they share the video at mission control as well when the day does come!

The sheer drama of how fast it comes down, the awesome power of the Merlin engine just blasting away delta-v... I wonder how many g's it takes on that final burn?

Would a drougue have simply added too much weight or too much complexity to deploy? I guess slowing down the freefall velocity before the burn just doesn't really help all that much?

Amazing that Falcon Heavy will have 27 Merlins on board.

People forget that Mayer acquired 56 companies (57 if Foursquare deal goes through). That is, 41% of all of Yahoo's acquisitions over the past 20 years happened in the last 3 years. Think it is important to analyze this Foursquare deal the context of this yet-to-be-proven strategy.

Back to this deal: Interesting possibility, for sure. Will it work out? Who knows with Yahoo.

Foursquare assets:

1) Brand name with both consumers and businesses

2) 45m daily active users

3) Valuable data- Can improve Yahoo Search, Yahoo ads, etc

4) Large group of domain experts

Yahoo's value add:

1) Yahoo does have a strong ad sales department, so it can bring lots of brand names to Foursquare

2) Can heavily integrate Foursquare into its search features- so Foursquare's DAU can stabilize/grow.

Seems like Mayer's strategy is:

1) Buy her way out of changing Yahoo's employees + culture. This is a longer term play.

2) Try to create some constellation of a platform. Ideal world for Mayer would be:

a) Get your homepage to be Yahoo

b) Read the latest trending headlines via Yahoo media

c) Yahoo stories pump up Yahoo-owned Tumblr blogs, Yahoo-owned Flickr photo sharing, etc

d) After that, you search for things on Yahoo. The search would ideally share information coming from Foursquare.

The big thing is on execution and that's why people constantly criticize Yahoo. If they do actually make a sensible platform, expect Mayer to be viewed very positively.
Stage separation is somewhere around 100km and Mach 6 or more. The exact figures will depend on the mission profile.

There's a "boostback burn" at altitude to slow the horizontal velocity right after separation, an entry burn to put it into the atmosphere, and a landing burn just before it hits the deck. The guidance in between those last two burns is aerodynamic from the grid fins.

The first stage mass is ~18,000kg empty (which it nearly is on landing), and it's coming in at its terminal velocity, which is, as a WAG, maybe 70m/s.

What's more, it cannot hover, as even one engine has a greater thrust at minimum throttle than the rocket weighs. So it must do what SpaceX calls a "hover-slam", and reduce its velocity vectors to 0 at the same moment its altitude gets to 0 in a single burn. Burn too short, you crash, burn too long, you go back up (and then crash.) And the horizontal vectors also need to be very small, and you can't end up too tilted either, or you fall over. And explode, because you're a thin-shelled tube with plenty of fuel and oxidizer still left. Oh, and you have to hit a very small target within a couple meters.

So it's a pretty tricky task. Plenty of rockets can hover these days, but landing a full-sized launch stage coming in from the edge of space is pretty tricky. And they almost got it. Looks like it overreacted just a hair to a gust of wind or something.

Your solution has two problems: (1) it cannot hover and (2) you'd have to design and build and test big robot arms. And put them everywhere you want to land. It's probably easier to make your big robot spacecraft, which you already have, do the landing itself on a plain concrete pad.
I just do not see why Box needed to create another Javascript framework. Am I missing something here? As a front-end developer I get excited about this stuff, but I just do not see what T3 brings to the table that other frameworks do not.

I appreciate that Box have released T3 for free and if people want to use, well then that's great. Nobody is being forced to use it, but it is situations like these where I can't help but wonder if efforts might have been better spent contributing to an existing open source project instead?

To me this looks very similar to AngularJS (albeit a little more stripped down). Looking at their example code, it just feels like they've made their own ES6 modules/class implementation. A better choice in my opinion would have been to take the same path that Rob Eisenberg with Aurelia has taken by making the framework ES6 and then providing Gulp and Babel to transpile it. T3 feels similar to AngularJS in that you spend an exorbitant amount of time writing class-like modules when ES6 and transpilers already give us a cleaner standards based approach.

I do not want to sound negative, I am just offering constructive criticism. I would love to hear the thoughts of the Box team as to why something like React.js would not have worked for them instead. Considering React.js promotes modular component development like T3 does, it makes me question if Box needed to build T3 when React.js and its similar MVC-less approach is the same. It is cool they did and it takes dedication and work to build a Javascript framework, but I feel like perhaps it is wasted effort.
Sane people do not say of a physical object "this does not exist". If someone denies reality so bluntly, they are beyond words. Physical feeling may be required.

I have a tendency to take things very literally when I am agitated.
The difficulty of switching is straw man. In Europe, a monopoly just means a product or a company with a near-100% control of the market. It doesn't have anything to do to the presence of competitors, the difficulty of switching, if the product is a commodity or not, and so on. In Europe, Google Search has >90% market share so it's a monopoly, and thus it is subject to regulations in the way they use their product they wouldn't otherwise subject to. The same will happen to Android as they approach 90% market share; Google will be forced to do things that Apple will fully get away with, because being a monopoly makes you subject to additional regulation.
Just because it is obvious doesn't mean "no docs" is ok. A high level API like this needs documentation for every function exposed. Reasons covered in the article.
I agree, this video makes it look like there was a strong chance that it could have been a success if the random variables on the way down aligned better. If it had of been they may not have learned and iterated based on this possibility and may have had a failure down the track.
Yes its a very hard problem but what makes it hard ? Is it engineering of the components, algorithms or expensive tests and economics of it ?
Maybe people before Elon Musk were not interested in solving this problem not because its technically hard problem but because their existing business model is much more lucrative.
I usually do something like

var Constants = {
valueA: function valueA() {},
valueB: function valueB() {}
};
The precedent already exists, at least here in Australia. Luckily it hasn't caused too many problems thus far, but whether that is merely an outlier remains to be seen.
I was wondering about that too! I guess it does make sense if the final burn fails to not have a fairly large bomb dropping at terminal velocity directly onto the barge! On land I guess less of a difference though...
Original situation: Search engines put snippets of news without paying

Germany passes a law: If you don't pay or reach another agreement you have to stop putting snippets

Google: I don't want to pay, you either let me use snippets free or I will stop as the law says

There, with the gaps filled in you can easily see the ultimatum from Google. In the Spain case there is no ultimatum, Google just shut down. In Germany Google looked at the law and then gave newspapers a final choice.

What's the difference between the tests on earth (as seen on youtube etc) where the engine runs the whole time and seems to display good throttle control and this type of landing?

Lets see, how much do you see Windows on:

- in-car infotainment systems

- in-flight infotainment systems

- running digital billboards

- mobile phones (hello android, meego, maemo, webos, etc)

- smart televisions

- smart dvd/blue ray players

- etc

You see Linux out in force on all of the above mentioned hardware platforms.

The global Linux installbase absolutely dwarfs Windows in comparison by the simple nature that Linux runs on more hardware architectures than any general purpose operating system ever created (which rules out iTron, eTron, and the tron variants).

Pretty much all of the new IoT "smart devices" are some Linux variant as well. I could go on and on, but really think you miss the forest for the trees here.

Yes Windows beats the snot out of Linux on the Desktop. The desktop is quickly becoming irrelevant as the world becomes more connected.
A drogue would seem unnecessary; a Merlin can scrub off plenty of m/s real fast, and if it can't do it fast enough, they have more of them. In fact, it might be easier if the thing is coming in faster, because you get to run the engine a bit longer and have more time to adjust your aim with the engine's greater control authority.

Anyway, they don't seem to have any problem managing the vertical velocity. It's been the horizontal each time. And this time, only a tiny bit off.
I think a lack of exersize throughout the day is why guys today are going bald earlier than in previous generations. I think high intensity exercises for 3 min every 1-2 hours throughout the day is reversing my hair loss. I'll be making a blog post on it soon with evidence of my progress.

Since August of 2014 I had been losing my hair. More and more of it was showing up in the sink drain. Earlier this year I got worried because it increased. I wasn't sure if it was a temporary thing due to stress or illness so I started saving up the little clumps of hair between paper towels and date stamping them. It just kept getting worse and worse. I got a blood test to check hormone levels and find out if everything's ok. I'm waiting on the results.

Last month I got tired of it all, and decided to experiment as a last ditch effort to prevent baldness in my late 20s. I started short but high intensity exersizes every 1 hour, for about 2-3 minutes. After only 1 week new hair has started sprouting up on my scalp. And the amount I've seen in the sink drain has gone down drastically. This is very odd because there's a huge delay in when hair grows and falls (often months) not 1 week. So I'm convinced it's the exersize that's increased circulation, jump started cell growth, and maintained healthy hormone levels. I need to test this out in the long term and try to get other guys to participate. I doubt it's a coincidence because 1 week I skipped my exercises and my hair growth decreased a bit and hair loss increased a tiny bit.

tl;dr The right dose of exersize for a healthy head of hair. Possibly.
Perhaps that's the right track, but now someone needs to invent one where you can just dump a kilo of regular coffee beans into the back, rather than supporting some huge multinational's billion$/year printer/cartridge revenue model.

Windows has required code signing for kernel drivers since Vista on x64.

Also, OSX doesn't require the kexts to be signed by Apple themselves - the requirement is that the kext is signed by a certificate that is blessed by Apple's CA. There are plenty of third party kexts out there.

Also, you can modify the bootloader's kernel parameters to disable kext signing and you will be back where you were on 10.9 security-wise.

A much bigger problem is how Microsoft is no longer requiring Windows 10 compatible PCs to ship with a way to disable Secure Boot.

NSA has contributed quite a bit to UNIX security over the years.
The Grasshopper tests had a full tank of fuel and (if I recall) additional ballast, to counteract the thrust of the engines. That's what allowed them to hover and perform the various low-velocity translation tests.

Of course, these barge landings are the first high-velocity tests, so there'll be kinks to work out.

Volkswagen Vending Machine Accepts Batteries as Money
SpaceX seems to be able to stabilize fine with RCS and/or their grid fins. The rocket design must be reasonably stable--even tail-first.

I don't think incoming velocity is much of a problem. Terminal velocity is gonna be no more than 90 m/s. The engines on that stage are more than capable of slowing it down--and fast. In fact, they're too powerful--it can't hover.
I didn't want it to be great. I wanted to tell the guy the answer he already knows: different coffee tastes different. Can't my comment be just not-great?

>A Vector Approach to Hashing

is something author didnt bother to test at all. His word list includes words with apostrophes (hex #27), like basic's, his code accounts only for ascii letters and crashes on that list :)

> its O(26) for list creation

hmm, no? unless python people create lists one element at a time ...tested and yes they do :o :D every additional byte takes ~10ms on my test computer(110K elements loop), hilarious :)))
Its cheaper to create two lists outside main loop, and simply copy empty list over the work list instead of creating new list every time (or resetting global list manually), we are talking ~10% of whole algorithms time cheaper. Python is one hilarious way of benchmarking algorithms. Simple x=1 in your main loop will cost tens of milliseconds.

>and its O(26) for creating the tuple

Ehhh :/ Yes, sorting is faster in python, ONLY because sort function is highly optimized low level code, while anything you write yourself will be extremely slow due to interpreted nature of the language. You can easily write O(n) hash routine in low level language (assembler, c) and beat nlogn sort.

>But, I think this time, we can actually use collections.Counter correctly

correctly? yes, faster? NO, ~10% slower. Again seems author simply assumed something is going to work and didnt test.

All in all main lesson from all this should be not use python to gauge algorithms speed, unless you are being hired to write speed critical python code (ahahahaha).

Hi,
Not on expert on get-back-to-tech but I vote for:
* Keep sending resumes.
* Do some side projects, and emphasis them on the resume.
For example if you'll create some cool site (check free tier servers) it may be something to show potential employers.
* If you have patience and enough will-power: Take any position in a tech company, and hope to improve position within that company. You'll have better chances if you'll go to a growing company.
The only way you can consider this "quite similar" is if you are using a rhetorical flourish to manipulate the listener emotionally. Which is, of course, what is being done here, and not for the first time on this particular topic.

Just remember, hyperbole serves no master. Employ it at the risk of having it employed right back against you.
