Totally obsurd. Gradient descent will 'almost' always get stuck in a local optima. The point of evolutionary algorithms, or any naturally inspired algorithm for that matter, is that it does not tend to converge upon local optima and has the possibility of moving out of this space towards the global optima. The fact that most problems it is applied to are NP-Complete means that it is unlikely it will find the optimal solution in polynomial time.

There seems to be something wrong with this commenting system. I tried to respond to someone who responded to what I wrote and the response did not take twice.

This is what I wrote:
Changing others, changing men, changing culture is very difficult. Nice to talk about it but it really doesn't happen. What one can do is to change themselves and part of that is understanding that those people are ASD are more likely to be insensitive than others and that is partially a genetic phenomena.
There is nothing wrong with women being more competitive than men in general and learning new technologies by going to meetups and otherwise. For example, most programmers know Java/Hadoop and far fewer really work with Scala/Spark. Learn advanced machine learning algorithms. Have a good understanding of computer architecture and computer chip fabrication.

I have been to a number of meetups and I have never seen any hostility towards women. These tend to be rather technical where meritocracy is respected.

In sum, those in technology are not wishful thinkers. One cannot change others, only themselves. Men are not going to change at least in the short term. I have given examples of a realistic means for dealing with the situation that I have seen women and others use.

Seems baffling to me that this wouldn't be a higher priority issue as this seems to be the commonest mode of use of Word for creating new documents - where the absolute commonest mode is using an existing document as a template and forgetting to change headers, metadata, and random boilerplate text throughout :)
> But as long as anything is scarce (and experiences are, broadly, and I don't think there's any way around that), we'll have something like "employment".

If labor isn't scarce (e.g., if there are easy substitutes that provide the utility provided by labor), then there's no real basis for employment even if there is scarcity in goods.

Scarcity guarantees that people will have an incentive to sacrifice to get scarce goods, but if labor isn't scarce, then sacrificing time in the form of labor isn't likely to be an option to do that.
payment processing, reach, marketing, infrastructure, testing/approval (you may or may not like this, but users probably do like it), app delivery, etc.

The problem is that the value of these things goes way down the more crowded the app store gets. Seriously, what good is approval in light of the endless legions of crapware and clones? How useful is marketing when discoverability is almost nil?

And how about free apps? It seems to me that paid apps subsidize free ones but that's a whole other ball of wax.
I remember discovering pivot tables in Excel way back when, and thinking that was a really useful tool. I was amazed to find that Google Sheets could do this too, and to me that marked it's promotion to my first choice for spreadsheet work.

I'm not a power user, but I'd say Google Sheets are good enough for almost all of us. Google Write, not so much.
> With inotify i use one watch per-folder, with kqueue you need to do it by file ( of course you can watch the folder changes, but you need to keep a copy of the file states in that folder, and then re-stat that files to find out what file was changed, not even close to an ideal solution ). So for example in my use case with inotify i can watch 65536 folders, and with kqueue less than 10000 files ( that could be a single folder! ).

Ah, I looked at inotify API briefly and did not notice that directory watches return file changes. That does make it easier to use than kevent vnode watches. Mea culpa.

As a PhD student here at Stanford, I find this really distressing.

For what little it may be worth to anyone reading this who is(/was) thinking about coming to Stanford, I have heard professors and grad students talk about ways to be more inclusive in their actions and language. I've heard my advisor stumble over "you guys" only to stop and correct himself with "you all". I can't speak for every lab (there are numerous, each with different cultures and norms), but hopefully I speak for everyone when I say that we grad students and the professors are at least open to learning about how we can make the CS program (and the field as a whole) a safer space for everyone, if not actively working toward that goal. If nothing else, we can promote an inclusive culture in how we speak, behave, and in what behavior we (don't) tolerate.

For Lea (and for countless others), I worry her perception of CS has been irreparably damaged. Hopefully that won't be the case going forward.
Based on what? They rewrote the language into another that is largely backwards compatible, fixes PHP's quirks and is insanely fast.

Given the choice of migrating / transpiling an entire codebase or making the underlying interpreter / compiler and language fantastic and speedy, the latter is a big, big win.

What would rewriting the whole thing in, say, Ruby or Python have done beyond limiting the amount of "PHP sucks!" critique they so often get?

Seriously, take a look at Hack. It's very well done.

My reply would be that if a programmer can out-account you as an accountant, then you've failed as an accountant; you need to look for another job or learn the necessary skills like programming.

Of course this does mean a lot of people out of jobs, which is the crux of the article, but I don't think it's a fault or weak link in this employment model.
While valuation metrics are one aspect of trading and I do think that most beginners do overlook the basics of them that should be covered before almost any investing.

For real returns it may not always be best to play it by all the metrics. It is important to note that the market itself fluctuates a lot on sentiment and sometimes a good valued holding can turn sour fast even with good metrics but bad timing.

Some companies will over invest in dividends which in turn means they are not investing in growth as much as they could be for instance.

Some companies will try to grow revenues but by focusing too much on the quick buck of short term and will not be as good for longer term with steep competition.

It is also important to note that the market reports of portfolio manager purchases like berkshire hathways tend to report just the stock name and not the amount they hold of that stock. As well as the fact that you do not see how long that portfolio manager generally holds the stock without constantly crawling that site daily. The portfolios holdings are only updated at the end of the day. So you can see recent purchases but you cannot see when they sell them until the day after.
> Right now, there's only a single package repository for each major FreeBSD release. The ABI doesn't normally change within major releases, so packages built on FreeBSD 10.0 will work on FreeBSD 10.1 (and vice verse).

And it's worth pointing out that the per-branch repositories are all built from the same sources — ports is not branched. The only reason to have separate release-branched binary repositories is for ABI bumps between stable releases.
Google has cars that are about to kill the entire transportation industry. Amazon already reduced the workers in some of its warehouses to biomechanical grabbing hands; all higher-order functions are performed by robots. No, I don't think we're giving too much credit to robots.
The premise of Uber is that there were tremendous and ill-gotten gains being nefariously produced by taxi cartels. By busting them up, they could provide people with better service at an equal or lower price - all while ridding cities of a nasty bunch of operators in the process. Behold the righteous cleansing power of creative destruction!

Turns out that their case was a bit overstated (to put it politely). Sure, this was a problem with the medallion model, and Uber is providing a breakthrough solution. But they're not stopping there. To achieve the growth that will justify their valuation, they've got to undermine perfectly reasonable labor laws as well. So maybe not so socially beneficial after all.

Sociopathic tendencies of the leadership aside, one has to wonder if the real problem isn't the VCs who poured their funds' money into a business that could only win by undermining clear, reasonable, historically necessary, and broadly popular legislation. Had they limited their investment to an amount that could be returned simply by attacking cartels, that would be one thing. But insisting that Uber illegally strip-mine their work force may have flipped a once-good thing into the extractive menace column occupied by outfits like...well, taxi cartels.
I'm afraid this post just comes off as hugely naive. They are a corporation, they will milk you and everyone else for as much as they can get in every way possible.
I don't forget that they pay for it, I just think it's so tiny as to not matter in this discussion.

Downloads are such an infinitesimally small cost, relatively speaking. I don't have comparable download numbers to the Apple store, but I do help maintain software that has 3+ million downloads a year (and it's a quite large download, too, compared to mobile apps, at 15MB). The cost of hosting those downloads and the bandwidth for them wouldn't even really be a blip on our radar in terms of costs of running our business and projects. Bandwidth is cheap these days. Hardware is cheap these days. And, it takes almost no hardware to serve file downloads. We've had people offer to provide mirrors for us for free, but we don't take them up on it (though we can't stop people, either, being Open Source) because we'd rather have the data about downloads than the tiny savings in bandwidth and hardware.

What's a few hundred terabytes a year of transfer and storage for apps to an organization like Apple, that also serves out millions of HD movies? It is closer to "nothing" than it is to "something".

You need to approach the company and provide them what you can offer to them, it shouldn't be the other way around "what can your company offer me?"
My point is that the following statement made further upthread is fundamentally incorrect as an assessment of systemd:

>systemd is a package of separable utilities, plus an init system. Much like the GNU core utilities.

The response was:

>So, how does one completely excise journald from a box running systemd. I'm not talking about passing messages through, I'm talking about complete, utter, wiping out?

The point is that if the utilities are truly separable from the init system (as was claimed by the first point as an indication that the person they were responding to didn't "get" systemd) then that would be simple. Note the person responding is responding to the assertion that they fundamentally misunderstand systemd. Their point is to show that they do not.

Your first response adds nothing to the conversation:

>If you want text logs, configure journald to pass things into rsyslog or whatever other logging subsystem you prefer (there are many).

Good point, except that's not what the person you're responding to asked for.

My observation is that systemd isn't just "an init system with separable utilities" that was originally claimed. You seem to agree with me.

Your last point, however, would have been helpful above:

> Anyone could implement their own journaling subsystem against the api and it would work... it doesn't have to be journald.

That would have answered the actual question asked.
Well, as vertex-four pointed out that API is not stable, and as far as I've seen there's no expectation that it ever will be. Feel free to correct me - for me this is the nub of the issue and I'd be happy to hear otherwise.
Technically combining stochasticity with gradient descent is not pure gradient descent.

As for the domain knowledge - this is not specific to gradient descent either, genetic algorithms and their problem encoding can be adapted to a domain to minimise the search space considered - therefore improving performance of the algorithm.

> and you have no way of automating yourself because you don't know squat about programming.

Automating existing work is more than just programming; a big part of it is expertise provided by people knowledgeable about the existing workflow. None of the projects I've been on that involved automating existing work involved only programmers and no one with experience doing the work.
It's as intended. If the ID in a list of 100 changes, and that ID is the key, React is going to assume the tree is different during reconciliation. If you were to use an index, like 0, on pagination the key is still 0 and as such the DOM nodes will be reused. http://facebook.github.io/react/docs/reconciliation.html See #2 in the Trade-offs section.
To be a bit contrarian though... there is a useful aspect associated with using labels, even in political/economic discussions, in a way that is similar to ascribing names to things called "design patterns" so that one can communicate concepts more tersely.

If done in good faith, I think it's legitimate to start with approximate labels, like "libertarian", and the arguing parties can then proceed to make their position clearer if necessary. Hopefully, this saves time.

Also, I think it's fair to describe someone that believes in the importance of "workers should own the means of production" as a marxist (at least it's more accurate than socialist or communist).
At present the only difference is the human brain is far more malleable and adaptable than is a machine. Our most flexible AI is generally based on supervised learning. That still requires human interpretation and verification to work properly.

I think you can also state that machines generally lack the ability to discern expansive context unless explicitly trained to do so.

Granted, it will happen. True AI requires these things. At present all ML needs a push from a human to become more "intelligent."

I would not be telling people to start making money off of shorts as their first few trades. Shorts are much more riskier than holding good amounts of selective monitored companies.

Most people should hold about 5-6 stocks that they can keep track of, but those 5-6 stocks should be well thought out bought on good opportunity timing with good metrics.

Calls and shorts are just for quick bucks. They can make you a lot of money with the right timing, or you could lose it all. It's important to read up and know what your doing before you decide to play with options.

I could have made a lot of money off of amazon when it went from 300 to like 360 or so in a day from the last quarter's earnings based on a call if I made it, but some bad news could have equally made the stock not reach as high as it did.

Instead what I did do was buy and sell the stock like 3 times or so before the earnings report making money each time, because amazon was hitting relatively noticeable support levels at around 300. I was also under the impression that they might make the earnings report but it may be on bad management or something which can result in stocks being devalued.

Amazon is a stock that has good potential revenue in many developing sectors, but it has not made net income greater than it's growing debt in 20 years that it has been on the market. It is a growing anomaly in the world of modern day trading but is an amazingly futuristic company.

Hedging is also something you only really do if you are heavily invested. Like buying a put on the S&P 500 if you have a large portfolio(large as in good % of your money) but you are worried about a stock market crash.
> Apple can absolutely afford to do this financially, but the 70/30 split is practically the only thing that hasn't changed in the App Store since it launched. So why don't they?

>A 70% take as a producer of goods is very high for a manufacturer that doesn't own the distribution channel.

Is there a competing distribution channel that iOS users are allowed to access? Or does the distributor lock producers into its channel? If the later, the distributor's take is completely arbitrary and can only be assumed to be selected so as to maximize the distributor's take of the producer's generated value.

As a Brit, I think this rather overstates the case. Take The Thick Of It. The article says there's no likeable protagonist, but Hugh Abbott, Nicola Murray, Peter Mannion are not unsympathetic characters, even if they're generally incompetent. I don't find the tone of Veep to be particularly less excoriating than The Thick Of It. If anything the members of Selina's team seem to be even more abusive to one another.

Whenever there's a discussion of US vs UK comedy and satire, I see the same cliches about unlikable protagonists and winners vs losers being trotted out, and I wonder if I'm watching the same shows as everyone else. Are the characters of Arrested Development likeable winners? Or Delocated? Or Bojack Horseman? Or Girls? Or Always Sunny?
People would game the shit out of a system like this.

Oh, our 'freemium' game just hit the 10% threshold. Better re-release it under a new dev account as shitquest-2 and rake in the moolah!
If I could sell it directly from my website the cut would be 100/0. I hate the indentured servitude imposed by the Apple App Store, and have opted out of mobile development thus far because of it.

It's like shooting off my nose to spite my face, I guess, given the growth of the mobile market, but I truly hate the shape of our industry these days, when it comes to how indie developers are able to connect to their users...yes, it's better than it's ever been, but not because of Apple. It's better because of the open web, and Apple and Google are using their near-monopoly powers to impose the old gatekeeper model long past when it should be relevant.
Exactly this. The hobbyist market certainly wasn't going to save them
Developers won't actually absorb the full discount. A decrease in the fee will force a drop in prices (if that's possible) as developers attempt to find new customers with their newfound margin. If you have a more price-elastic customer base, those customers will reap most of the value of the shift as many will come to enjoy their lower prices.

Secondly, wouldn't this create the perverse incentive for developers of multiple apps to release apps under multiple accounts--some might call them shell accounts--in order to minimize their app taxes?
Absolutely, technology of some kind will be able to replicate all human domains of intelligence at some distant point in the future, but our own minds will be continually extended (with lower and lower latency, and increasingly reliable interfaces).

The question becomes moot as humans and machine coalesce.
Outperform on what? Can you give specific examples? There are a large number of Combinatorial Optimisation Problems. It is a very sweeping statement to say 'gradient descent techniques far outperform evolutionary ones'.
Yes, I know, and I appreciated that fact in the post upthread. The point here is, if you go with the suggestion of 'redemeer that "if you get automated away, you get 0", said accountant will have no incentive to help with the automating, and every incentive to make it as hard as possible - which I think is not the result we want to have. To get a happy ending for everyone, we need coordination, not competition.

Couldn't you just have (by hand) created a tree/commit/branch referencing the object, pushed it to the server and then fetched it (possibly to a new clone)?
well even if they take 50% cut, developers are not going anywhere else. So, the equation is more like whatever cut apple takes = more developers =...= more revenue
