2013 ? Would gladly see the same benches with Go 1.5.
I'm very interested in Starfighter and am looking forward to the release. However, there's something from your original announcement that still worries me. In this post you said:

The designed operation of our trading levels is “Play them, lose horribly, write a program, reset the level, run the program, have it crash with a bug, fix and re-run, lose modestly, adjust your approach, re-start the level, run the program, win.” (Folks have asked whether we’ll hold this against you. No, no, of course not. We log everything under the sun, but losing/restarting levels is planned. That capability is an advantage of doing this in a rich simulation as opposed to real life — you can go Knight Capital as many times as you want and no one loses their job!)

This feels good. But earlier, this was said [1]:

We will track player behaviors and skill at incredible levels of granular detail, instrumenting them like they were built by the Orwellian MiniPeace... We can tell you exactly what happened when your candidates tried to implement a REST API. We can compare their performance against hundreds of other talented engineers (including your current employees) on the same task.

Can you please elaborate on what exactly is going to be tracked? Is any of this configurable by the player? Personally, I'm going to have a hard time enjoying and learning if I feel like every mistake I make, or every extra piece of time something takes is going to be judged and count against me later on.

Yeah, or protesters and celebrities. It could actually be anyone and celebrities, because you only see the groups that you participate in, and the only one with global visibility are, duh, celebrities!

I think Twitter's biggest problem is lack of vision and a commitment to that vision. Going public was a big mistake for them, because Wall Street has no concept of what makes technology good or interesting over the long haul, they can only reduce things to the most simplistic metrics. Facebook is pretty much a known quantity at this point, and is the biggest social network that has ever existed. So now everyone wants to measure Twitter by the Facebook yardstick. But Facebook only has 5 times as many active users as Twitter, and I would bet money that the average Twitter user is more than 5 times as influential as the average Facebook user. If you can't build a viable company with 300M of the most influential users, then something is very very wrong in the world.

The biggest tell-tale for me is that everyone knows exactly what Facebook is, and many people (especially younger ones) see it as a crufty accumulation of old friends and family that they have no interest engaging with. But for Twitter there's still a majority of people who "don't get it", and yet it has been a revolution for celebrities and the aforementioned groups in terms of what it's done for the public conversation. To me this is all an indication that Twitter has way more upside than Facebook. In fact, I'd be willing to invest in Twitter if I thought their leadership was strong, but my big concern is that they don't have a clear vision, and therefore they will get picked apart by the clueless hand-wringing of Wall Street until they become so cheap that Google or Facebook snaps them up.
Your comment was too long and was not respectful of my time. Couldn't you have found a way to convey your sense of entitlement to the content that other people freely provide you in a more succinct way?

> Now you know why I deployed security-focused stuff on PPC at one point. The economics of hacking alone work in your favor.

Perhaps true for a small-time, individual hacker. Over a decade ago, I recall being quite impressed by a professional pentest team whose tools included a lovely exploit authoring DSL embedded in a popular scripting language. That DSL allowed them to write "abstract" descriptions of specific software exploits, ala vs openssh vX.YpZ, then "render" (~~ compile) the exploit code automatically against any of their supported target architectures and/or OSes. (i.e. all of them.) Even though perfectly capable of it, they got tired of manually porting everything around.

This has also been a strong reminder for me that exploits are usually against the software, irrespective of the hardware architecture. It's easy for folks to get mixed up about that.

For something like hacking a PS4, the "obscure platform" logic might apply(), but never assume it applies to any attacker who can afford (n.b.: not just build) a sophisticated attack platform.

() With the caveat that now it's a numbers game, and you're up against bored teens/tweens with way too much time to throw at the problem.
Ruby did not popularize nor invent REST. The other points I don't feel like arguing about..
Given that aircraft fly faster (in the case of large aircraft, a lot faster) than these drones, the article's choice of words that makes it sound like the drones "buzz" aircraft seems pretty misleading. It's the aircraft that fly into the drones, not the other way around.

The real issue isn't what the drones do, it's that they're around at all, because the speeds and sizes involved makes it very difficult to see and avoid them whatever they do. In that sense, they're not that different from birds.

There sure are a lot more birds than drones, but on the other hand I'm not sure what the relative effect on a small aircraft from the impact of a (relatively soft) bird versus a (hard) drone is.
The global temperature results are often presented as NASA, NOAA in dual briefings, though sometimes the other way round, probably depends whose turn it is to book the hotel - https://www.nasa.gov/press/2015/january/nasa-determines-2014...

They do individual analyses, but by and large, NASA manages the kit.
Basically, it's another SLA printer, but they use an improved chemistry to speed up the process.

Autodesk, which now builds a 3D SLA printer for about $5000, has been experimenting with chemistries in that area.[1] They give more info about the materials used and the results.

3d printing of injection molds is already being used for some low volume medical products.
In my heart of hearts, I want to think that TMO understands that the networked future everyone raves about won't happen because data transfer is too costly to make it practical.

Mobile devices are wonderful, but come on, the price of mobile data is assault with intent. I don't mind paying for my data. But I do object to being abused for wanting to use the network for non-trivial activities, such as twitter, farcebook, etc.
Twitter is huge, it costs a lot of money to run. They had a net profit of negative $162.4 million Q1. I don't know what defines an $X0 billion business, but I would imagine that it would be profit.
I see a problem. They use data from in vitro fertilization to conclude the primary ratio is about 100. That's neglecting a part of the natural process that could introduce a bias. While earlier on the author rejects a couple of measurements due to their mutual inconsistency - even though they were both above 100.
Bah, I was afraid that throwaway part of my comment would end up getting the focus. My point is just that most people are somewhere in between "want to get drunk" and "don't want to drink at all" when they're socializing, so drinks optimized for that make a lot of sense.

Injection molds need to be ridiculously precise, as in 1/1000 of an inch of can render it useless. Also, I have doubts that the layered result of 3-D printing can hold up to the extreme abuse these things get put through after tens or even hundreds of thousands of cycles. We are talking about foot thick plates of steel bending and warping from fatigue damage after a while.
Even if you could 3-D print the bulk of it, the job of polishing and detail work would still need to be done manually.

Edit: after Reading the comment below, I admit I may be somewhat biased from working with more complex and detailed parts with very right tolerances, so there may be some applications where it is feasible. All the molds I've seen/worked with were made the old fashioned way.
> What are you blathering about?

Whoa. You know you can't do this here.

This comment would be fine without that rude bit. Please edit personal abrasiveness out of your posts on HN.
yeah sure - I was a bit troll-ish in the language. Let me elaborate. Imba is a spin-off of javascript intended for front-end use whose syntax is a mix of coffeescript, jsx and python as well Ruby imho; that said, please name a single use case in which Ruby will be without a doubt the #1 language for performance, scalability and all the other aspects involved in maintaining a business (including availability of programmers). Ruby is only second to PHP, which is just unreedemable (I'm even certified on it... http://www.zend.com/en/yellow-pages/ZEND005898 so don't think I'd refrain from criticizing languages I know, even very well).
There are those of us who worked under these A-player only regimes, and have had our fill of them.

They'll have to recruit younger and/or more gullible or financially hungry candidates, who are willing to burn the candle at both ends.

Those who have worked in this environment for a number of years usually don't want to experience it ever again.

Maybe if you can sustain this A-player workload forever, you might be better off becoming a founder starting your own company. For a lot of us, we just don't have that kind of drive (at least, not after a few years at an A-player only company).
It's a fantastic example, isn't it? I had to give a lightning presentation about a topic in linguistics for a class and the SWS synthesis demonstration grabbed the crowd's attention like nothing else.
How about backing these assertions with real data? Can YC show that companies are more likely to flatlines post-YC vs. while being coached? Or is that simply due to fast growth being hard to sustain? A careful statistical analysis of the growth of their companies, given the large sample they have, could have made this an interesting post rather than just a smug one...
At one point Facebook's stock also fell below IPO price. It happens. I hope they will come back like FB.
> Twitter had a Q1 revenue of $436 million

They're also consistently losing money. Even if you strip out half their capital expenditure or 3/4 of their R&D from their FY 2014 numbers, they would still lose money.

Let's say they can eventually run a 20% net income margin. This would turn their 2014 revenues into $280MM of earnings. Using the S&P 500's 21x P/E ratio, this values the business at $6bn. That's 70% less than their current market cap. And they don't appear close to running a positive margin, let alone 20%, on their 2014 numbers.
It's like design patterns where couple of words would encapsulate a lot of information. If they do anything novel then they would need a bigger book(boat).
1) NDA may stop someone from disclosing information.... it may not, but it may. That has a degree of value and the document is generally pretty short and simple to understand so not too problematic.

2) for the same reason many people will not sign an NDA (trust, hassle) you may want them to- trust, commitment.

3) even if an NDA only serves to regulate "the aftermath", that too can have value, especially in the rare but possible cases of mis-use of information e.g. by a competitor...
> There is a lot more you can do with 1h per day than you think. If you're consistent.

Or, for some of us, there's a lot more you can do with 1h per day than you think, if you're willing to let that one hour consume your thoughts for the rest of the time you're awake. That's much more my concern than anything else --- when I'm at work, I need to think about work.
Slack but not being tied to a single dictated user interface completely controlled by a fickle startup's whims.
Which reality is that? The one where people believe that just using a web page creates a contract with the website owner? Don't be ridiculous. This is not what most people subscribe to, even though big media corps and you would like them to. It is not the reality, it is a pipe dream. In reality, contract/trade happens by voluntary agreement on terms by both parties.

Remember their incentives. They want you to perform well (or more precisely they want performing well in their game to correlate with you being a good employee).

It is not in their best interests to count against you, quite the contrary they want to sell you to their clients.

I would say normally when you are using monetary value as an adjective for a company, you are describing how much it is worth, not in relation to revenues. Most companies do tend to have Revenue/EV multiples greater than 1.0, so more times than not, that would be correct. However, I would not say that would always be the case.
Only if you are editing the germ line, as with any other method.
The entire point of the article is that it isn't that clear.
My favourite story on a similar note is how a Marc Jacob's boutique was vandalised a few years ago. The vandal spray painted "ART" across the front of the store. Marc Jacobs responded by photographing it and putting it on a teeshirt and selling it for $700.

Twitter hasn't focused on anything else besides twitter. Facebook is taking on the mission of "connecting the world". Google has gone well beyond being only a search engine. Amazon has expanded into mobile, AWS and ...

Twitter, on the other hand, is still pushing the same product.
I suspect Alaska Airlines will not appeal this to SCOTUS, doing so is risky. It's just better to leave it localized to Washington State.
It depends, even a book "documenting the process step by step" could be a lot of things. Is it a tutorial? Is it an interesting discussion of emulation that uses the construction of one to frame that discussion? It is device specific? Is it about that device or is it about all devices, again framing things?

The book itself sounds fine. The way you're selling the book (both on here and on LearnPub) could be improved. You need to decide what the point is REALLY meant to be, sure the theme is emulators, but if you have to describe it without using the word emulators or talking about any specific tech, how would that sound (e.g. "educational," "history," etc).
"and poor execution is why they don't"

Luck and timing no doubt play a very important role in addition to simply poor execution. Also even excellent execution doesn't take into account how the market will respond to what you are making or trying to sell which can't always be determined prior to actually going through the motions.
Am I the only one who never really liked the whole concept of Twitter?

> Evolutionary pressure has adapted us to an outdoor agrarian life.

If that was the case, you would still be poking some rock with a stick covered in mud growing some wheat instead of typing on a keyboard, talking to somebody over the internet.

Evolutionary pressure adapted you to have a malleable brain capable of whatever is needed at the moment.

> Its entirely possible to deliberately design people who fit into modern cities.

Sure it is. Because we already fit into modern cities just fine. They're designed to our nature, by definition, since we designed them.

I search job board aggregators and do my level best to filter out agency recruiters. I don't trust the exact job numbers, of course, but I trust the rankings because the deltas are large enough.
I've found myself where you are at multiple points in my career. And each time, I made a leap to a new domain. Not wildly, but to an immediately adjacent domain that excited me.

With 20 years of experience you potentially bring far more to the table than "just" your dev skills. The great thing about being a developer is that you touch a lot of other domains...often at a fairly detailed level of understanding (I learned more than I ever wanted to know about the credit card industry by developing commercial credit card processing software for gasoline dispensers many years ago).

Of course, this is how many devs end up becoming managers...though you say that's not where you want to go. But there are other paths as well. For example, a Product Manager with strong development skills can have a significant edge over someone that's come up strictly through marketing.

People who can straddle the boundaries between domains of knowledge have unique value. At this point in your career, you likely possess knowledge and skill beyond just ASP.net development...skills that startups or companies would find valuable.

I originally came out of physics around the time of the collapse of the SSC project. I saw colleagues with freshly minted PhD's in theoretical physics (NOT a marketable degree...except for driving a cab) go off to Wall Street and become quants...and do quite well.

So the core question is: are you locked into thinking of yourself as just one thing ("developer"), in which case the search is for what kind of developer you want to be next...or can you think of yourself as someone whose years of experience bring unique and valuable expertise...in which case the search should be broader and more unconventional.

It's less about what the external trends are; more about how you can reset your internal self-image...and your willingness to make the investment to bring that into reality.

Of course that means adopting entirely new strategies for finding where your skills have value...those types of jobs aren't posted on HR job boards.

Personally, I've made some huge career and domain jumps over the years (physics, software, large-scale databases, robotics, biotech...and various startups). It can be challenging...and a little scary (but only in the roller-coaster/skydiving sense), but It's also made for an exciting life that's largely been quite financially rewarding.

Never be afraid to jump out of the box...

I have some ideas jumbling in my head about this, but it's getting late and I'm not sure they're maximally coherent. Briefly:

a) What's the worst thing that possibly happens? Someone scams a row out of our database? It has more rows. 10,000 someone scams a row out of our database? I will write a for loop which scams a million rows out of our database. What about the actual world or Starfighter's capability to positively impact our players, our customers, the industry, or our own situations just got worse as a result of that for loop?

2) I think you will find that a solution which beats level six also sails over the Turing Test, so if you have a tiny script which does so, I recommend not burning it on Starfighter, but would be honored if you decided to try.

3) At the end of the day, the model is not "Someone pays us for a PDF automatically spat out of our database", the trivialization of which PDF would be dangerous to the business model. It is "We become sufficiently enthusiastic about someone's performance that we successfully introduce them to a company which is not us and then that company hires them." Is the threat model "You use a script which trivializes our levels to win a free conversation with Patrick about your career?" Anyone can get that! At any time! Save yourself a git clone; just send me an email!

The more interesting question is then, given that you've learned absolutely nothing from Starfighter because you've git cloned your way to the finish line, whether you can (in thirty minutes with me, or Erin, or Thomas) convince us "Yes, this person is totally someone I should burn my stack of accumulated karma with the CTO of $CLIENT with to suggest they interview them."
Twitter should do group messaging and structured tags. I want to do things like:

@friends Don't forget my birthday party on #(Aug 20, 8pm) at #SomePub

or

@friends Don't forget my birthday party! #invitation(Aug 20, 8pm, SomePub)

And I want to be able to create a list where all invitations from people in the @friends group go

And finance people could do things like

Twitter has bottomed #buy(TWTR)

And I want to be able to specify a rule that makes these messages go to my stock trading list

Ask HN: Best way of learning mobile dev from a webdev background?
Hi all, I have a webdev background (worked with python/django, C# and some php), and also at university I did some C/C++, now learning java.

What resources/books/anything would you recommend to get up to speed in mobile development, considering that I have some knowledge about web development and programming in general?

Thanks in advance :)
"Not all violent offenders are murderers and serious assaulters, and many
would likely be better served by not being incarcerated, but the optics and
political risks of violent-offender decarceration are much tougher to navigate
than those for drug offenses."

The Big 4 violent crimes are murder/manslaughter, rape, robbery and ag. assault. Of those 4, it's easy to get charged with the last two. For instance: I was "gently mugged" at night a few years back on my block; 3 teenagers jumped me and demanded my phone, which I gave them, and my bag, which I refused to give them, at which point they ran. They were charged with robbery (I didn't bother showing up to their trial, which I understands means they were acquitted, which seems like a decent outcome).
