The fallacy there is that their push to promote big Warner is mostly promoting toxic games that milk and dime users because freemium games is where money is at.

It's no coincidence that on both stores you cannot filter out apps that have in app purchases
Yes, that's my point — you don't need to not have an M.D. to spout completely false medical claims on television. I think he's a quack and his license should be revoked.
Does it qualify as justified when it amounts to essentially stealing from everyone else in increased costs at decreased productivity enforced via violence and the threat of it?

I mean the South attacked Fort Sumter because they might eventually have slavery phased out. Just because they were accustomed to it doesn't mean they are justified to it forever.
apples “tax” is for digital items sold for use in the app itself; for physical things or download codes for game consoles etc, then apples “tax” doesn’t apply (yet heh)

technically it’s called “in-app purchase” [1]

I'd replace Netflix with Microsoft.
Yes, you need a nosql graph databases only for applications that require eventual consistency - and that's a hard thing to get right in any case; an application can do without that if does not have to scale to a very large user base.

In any case putting the graph nodes and links into sql tables is a much easier to do option.
I suspect a lot of people feel that part of their conspicuous consumption is part of the effort to earn more. You have to wear the right clothes, look the right way, have the right tech - or at a higher income bracket, be part of the right clubs, in order to socialise with the people who will pay you. So the two are sort of linked I suspect.
> That sort of abuse can be self-propagating: it becomes a learned behavior that turns victims into new abusers.

That makes a lot of sense. Come to think of it, we started having those problems after a string of very aggressive or very anxious managers.
AFAIK that's not how it works. For example go look up Microsoft's monopoly. The commonly held believe is Microsoft was declared to have a monopoly on personal computer OSes but that is false. Microsoft was found to have a monopoly on OSes for Intel based machines. So by that same logic Apple has a monopoly on OSes for A series (A10, A11, A12) based smartphones.

Microsoft Research does a lot in AI but don't forget FAIR, Nvidia, Baidu, and Amazon. Smaller companies like OpenAI are making strides too.
Why do you say "wrongly"? It's one thing to punish bad speech; it's quite another to block furture speech which may be good or bad. Generally the first amendment requires punishing speech after the fact outside of some narrow circumstances.

It's not clear to me how the university would block only threats in the future without restraining potentially legitimate speech.
I’ve yet to see a company with no managers work out. Usually it signals lack of bandwidth to set up management, low perceived value, or pessimistically a cost-cutting measure to double up on responsibilities.
Well, native has it even longer (WPF behaviors and grid), but I have to put up with Web for most of my projects.
Ah, the good ole no true engineer fallacy.
> Why call it "tax" if it is a fee?

Tax instead of a fee because it's unavoidable to do business on the platform. Akin to a sales tax to sell items in an area. Terms are fungible but it's a reasonable term.

> I have no horse in this race, but the author seems to have

Assuming the author has bias repeating a commonly used term indicates more about bias on the assumer than the one using common terms.
Aggregation is also helpful for search, which is the main thing I do in the app store
Better port that sucker to Postgres sooner rather than later. You know, for future proofing.
PGMs were in fashion in 2012, but by 2014 when Deep Learning had become all the rage, I think PGMs almost disappeared from the picture. Do people even remember PGMs exist now in 2019?
It may not be new to you, but I bet it is to a lot of people.
In my city, there are 5 high schools in different parts of the city. There is a huge difference between the rankings of 2 schools compared to the remaining three. Funding and teacher pool are pretty much the same source. The main difference is the students and their families. The parents in those areas are well educated and have high income. If anything the best performing schools looks like a dump compared to the 3 lower performing ones. I'd say student background plays a huge part on their performance.
Can someone ELI5 what can be accomplished with these devices?

I am not familiar with them, and the build looks simple - but what do once created? Is it simply a BLE beacon?
Would that actually qualify as more just? They are deciding that more people must die just because they don't want to give up their illusion of control. Since you can die just as well due to a driver legally in the right in an accident with nothing you can do to stop it.

Just because it may be consensus doesn't make it remotely rational or right. I mean mobs lynching every suspect would ensure more people are held accountable but mean more innocents would die as well.
I don't get why DIY/Maker folks are so extremely bent on finding and buying the cheapest shit from China in every regard of their builds.

> Just because you conceptualize it in your mental model does not mean you need a graph database.

Yes! When I was younger I worked on a problem once that needed to compute some very basic graph metrics. My seniors tried to do the work in an early graph database and it was a disaster. It turns out literally just reading in the lines from a file and counting things got the job done in a few seconds.

They refused to use the results until they were coming out of the graph database because "just in case we needed other metrics". We never needed the other metrics.
FTA:

"So it didn’t learn how to make one from the other. It learned how to subtly encode the features of one into the noise patterns of the other. The details of the aerial map are secretly written into the actual visual data of the street map: thousands of tiny changes in color that the human eye wouldn’t notice, but that the computer can easily detect."

I would not have used the word "secretly". The buildings and trees were filtered out, but not completely. The reverse transformation just amplified the noise back into buildings and trees.
It could also just be a poor choice of words, for which the charitable interpretation is that he's explaining.

Let's say, hypothetically, that he uses the word "understandably" instead. Would you consider that explaining or rationalizing? If you would consider that explaining, then maybe he just chose his adverb poorly. If you would consider that rationalizing, then I don't think there's a charitable framing of the point that you would accept as just explaining.

People here clearly disagree, which is fine. However, I'm seeing a lot of the unnecessary habit of discourse where people are trying to frame a disagreement as moral high/low ground.
As a data point, which I don't think is a huge outlier: I have paid $5 for lots of apps I like, which I would never ever have gotten around to paying for on someone's website -- partly trust, partly just mental overhead. But whether the app is $4 or $6 makes zero difference to me.

I don't think I found any of these through their listings or search, maybe those could be better? But the space is huge, maybe random blogs etc. can do better than any centralised store.
The vast majority of App Store revenue is games.
Always find people amusing who think identity is built around a person currently employed because of their skill-set.

I recall talking to a person years ago when I was between jobs as a [job title].

"What do you do?"

"Oh, I'm a [job title]."

"Oh nice. Where do you [job title] at?"

"I'm not [job title]ing anywhere at the moment."

"Oooooooh, well! Then you're not a [job title]!"

By this logic, you're not a blacksmith if your not pounding out red-hot horseshoes. Or a doctor if, after 20 years in surgery, you've granted yourself a two-year vacation in the Bahamas.

In this POV, though, ex-political leaders, ex-military leaders get to keep their titles. Say what?

Linkletter was right: people are funny.
This is not to say that his advice is useless. I think it can be useful from certain contexts in life. But for any ultimate achievement in what is humanly possible one needs to look beyond what he professes to be possible.
No.. no it isn't. Where did you even get this idea? Are you planning something? If you kill anyone, at all, self defense even, you are definitely going to jail. Then a magistrate decides what to do with you the next day. There is no situation where someone is dead at your feet and the cops are just like "yeah sure bud see ya later". Even if they believe you. Even if there's video evidence on hand. Lastly, whoever is telling you this "running joke" stop listening to them. You will absolutely be charged with vehicular homicide. Even if you can prove the person jumped in front of your car. A jury can convict you on the basis that the prosecution makes a compelling case that you had a few seconds to break but you didn't. Murder ain't no joke pal.
Are you serious? It make it easier for everyone to get into, especially kids.

Also makes it so you can use it on small projects that might not work and not worry about it failing, or losing it.
maybe 'product development' ?
That sounds a lot like losing your wallet or dropping it in the sewer. Except that losing your wallet is a lot worse. In the situation you described, I'd just borrow the driver's phone to login on WeChat and pay.
Other than SSL are there any other parts of websites and web presence that are relatively expensive now and could be done pro bono non profit? Maybe a TLD domain that would be absolutely free??
Aren't biofuels carbon neutral? You have to capture the carbon from the atmosphere to make the fuel.
Having worked with a ton of ESP8266 variants, I agree with this. (The D1 Mini Pro has more RAM and is great.)

The ESP32 is good out of the box, and can be even better if you need dual core or Bluetooth.
I'm the opposite. In fact I'm so opposite that I grew up assuming that the majority of the people on earth are more like me than like you.

A study such as this definitely makes me suspect that I may be the the minority? Who knows?

Cuteness as an emotion has never overwhelmed me. Cute is pleasant to me like a pleasant color or my favorite geometric shape. I recognize cute but I can't relate to being completely overwhelmed. Most of the time I ignore it.
Ask HN: How do you find roles as a solo developer?
In my last gig I spent a lot of time working as a solo developer - essentially as a one man programming, testing and project management army - and it was one of the most rewarding experiences of my career. I loved the variety, responsibility and self-reliance.

Now I'm looking for another role, but am having trouble finding similarly individualistic work. Every org seems to be recruiting devs who can just happily slot into their "cross functional agile teams" - and this isn't me at all.

For context, I am a full stack JavaScript / TS developer with experience in web graphics and VR, a little C++ and Java too. I live and work in London.

Can anyone who works this way currently advise on how they obtained their position?
> Like the parent here said, more integration with the company. I want to celebrate successes, have input on projects, and know my coworkers. I don't want to be a task hamster running on a wheel of endless tickets.

This is an interesting idea and might work really well!

Currently the hamster wheel ticket thing is a demand from engineering, but maybe suggestions for changes would be welcomed by the team.

The other things, we sorta have it all, I think? I asked a friend about the Spolsky Checklist and we pass it.
Somewhat related:

A few yeas ago I used SpamBayes. The program calculates two values independently:

* The "probability" that a message is spam

* The "probability" that a message is ham (not spam)

They aren't real probabilities and they don't add up to one. Usually you get one value that is close to zero and one that is close to one.

Sometimes you get two values that are close to zero and it means that the email is of an unknown type (and you must classify it so the program learns to classify similar messages) and sometimes you get two values that are close to one and it means that the email is of a weird type (and you must classify it so the program learns to classify similar messages).

So the programs "knows" when it is confused.
So you need to spend at most 40% of your income on food, shelter, etc before you can save anything because you need to spend the 60% on what, occasional emergencies? What do people do when they don’t have that 60% spare? Or is the key that you write “actually save money” and by that you mean saving some significant amount of money? How much do you think that is?
> Cities shouldn't be designed for cars. If anything, it should be the other way around.

Sounds like a perfect being the enemy of the good issue. Whether or not cities are designed for cars is separate from 'should the cars be self-driving'. That sort of hairshirt anti-harm reduction has a poor track record.

> The whole idea of suburbs throughout human history was the luxury of not being in a city, but thanks to that mentality + the Baby Boom, modern cities are now glorified business parks.

That isn't true actually historically it was the reverse where the outskirts of the city were where the poor went, especially when it meant being outside of the protection of city walls! We are just seeing the trend reverse itself.
> at percentile X would substantially improve their financial security if they spent as much as percentile X-10

This is spot-on.

It's worked for me -- I didn't have a solid handle on my finances when I moved out of my parents' place, so I lowballed and found a place I knew I could afford even with a pretty pessimistic view of financial discipline.

Nine years later I'm living in the same place, and I've gotten a raise every year, so I'm making quite a bit more than I was back then. Driving an even more economical car. Eating better -- buying groceries instead of eating out all the time.

I could fritter it away, let my ISP bleed me dry with a $162 cable+internet+whatever+modem plan when the $30 plan works just fine and I bought my own modem. I could shovel $95/mo to Verizon, but I'm on Ting and I use wifi whenever possible, and my bill averages $26 and I own the phone.

I could send $8/mo to Hulu and $15/mo to HBO and $11/mo to Netflix and $13/mo to Amazon and $10/mo to Spotify and $10/mo to Pandora and.... how many more are there?! But I don't feel like my life would be improved by having all those. (I do Spotify, but none of the others. In the event that I feel like rubbing my nose in a pile of TV, there's this thing called broadcast.)

I feel like there's a never-ending stream of these things, with their pundits on the morning show and Weekend Edition making you feel like you're missing out on life if you don't watch at least one show on every such service. And Disney+ is coming...

To me, it's that incremental monthly spending that inexorably, insidiously, increasingly, gobbles up every spare dollar the middle class can scrape together. I've been literally counseling my friends on how to talk their cable providers into a lower rate.

Many of them didn't know that was possible.

Cancel your shit, people.
>That sounds a lot like losing your wallet or dropping it in the sewer

You have your phone out all the time. The risk of losing/breaking it is significantly higher than your wallet which sits your pocket 99.9% of the time.
Please don't. You are who you are and people will like you if you accept that maybe you're not perfect - like everyone else. It's always going to be awkward, but own it and you'll be a fine man\woman or whatever/
IANAL, but I am a lawyer.
Burning cow shit smells welcoming? I'd have thought it'd stink like cow shit and smoke. What does it smell like? Genuinely curious!
Because there is a lot of things I would like to buy now that I have no money for?

My ideal doesn’t change when my income rises, I’m just finally able to pay for the things I’ve wanted all along.

At least, that was true before. I guess I’m finally at a level where something remains for saving.
What happens if Apple bans Netflix and provides a steaming and alternative?

I guess Netflix can sue them, but in the meantime will lose a lot of money.
The nonlinear kernel SVM works at least as well in primal, using just the representer theorem. Since it is unconstrained, all you need to do is create a kernel matrix and solve your system with your favorite convex optimizer like Newton's method (which also can work in lower dimensions).

Second-order methods like Newton's method converge better to the exact solution that SGD, although they don't reach a "pretty good" solution as fast usually. Coordinate descent methods in the dual also get very close to the exact solution, but Newton's method and friends are usually faster. With (quasi-) Newton methods in the primal, everything just comes down to solving linear systems, which is a much more well-studied problem.

I've even experimented successfully with kernelized models with millions of examples in low dimensions using the Fast Gauss Transform. That's impossible in the dual.

You can also generate low-rank kernel approximations [0] using the Nystroem method or the Fastfood transform that can then be used in a linear SVM. For example, if I had a problem with n=10^6, I can make a low-rank approximation of the kernel matrix (say d=1000) and feed that into a fast SGD optimizer.

This often works really well, and is usually pretty close to the exact kernel solution if the problem is of lower intrinsic dimensionality, which is usually true if the dual SVM is sparse in its basis vectors. This largely negates the sparsity advantage of the primal SVM. If a kernel approximation isn't good, then the dual SVM wouldn't be meaningfully sparse anyway, so there is still no advantage of dual. Best just solve the kernelized system in the primal, and use a second-order optimizer if needed.

"Better the devil you know."

Without exception, there's always a downside to everything. Familiar pitfalls are easier to cope with than unfamiliar ones.

It's often only well after the fact -- like after you are dead and gone in many cases -- that the full scope of the cost gets recognized.

In the course of her work, Marie Curie was exposed to high levels of radiation. She had no understanding of the danger involved. We have some idea now, but it probably wasn't well understood within her lifetime.

Now, we have standard protections for handling radioactive materials. But those protections were developed at the cost of lives and much suffering.

Progress involves "Eating of the fruit of the tree of knowledge of good and evil" and all that. (IIRC) In the Bible, this was the introduction of sin and the cause of the fall from grace. I generally think if the Bible as full of excellent metaphors for general principles of this sort.

(No, I'm not up for debating the Bible, actually.)
Generally, you don’t run out of roof space before meeting a 2 story buildings energy needs. On taller buildings installation costs would be significant, coupled with lower effects and it’s more viable to put them just about anywhere else.

The garage door is a rather complex place to put them as their are a huge range of styles and you would need to either fit the opening and replace the mechanism, or design a door for each existing type sold. On top of that wiring up solar to your house is the tricky part not putting something on a roof.
Because cost is prohibitive.
Or, look at it differently: we've increased our renewable energy capacity percentage by 42% over 12 years, even as world energy demand rose. (0.1/0.07 = 1.42)

This is great news! In about 75 years, we'll use >90% renewable energy. (1.42^(x/12) = 0.9/0.1)

Which of these is the better model? I don't know, I can't eyeball statistical regression on this chart. But my gut says percentage of energy use growth isn't what we should pay attention to if we want to predict the long run future. When/if renewables become far cheaper than coal, that percentage is going to skyrocket fast.
Ask HN: Is Battlecode a good way to learn AI/Algorithms?
I'm a complete beginner to programming. I have been learning Java for the past few months and wanted to get some experience with algorithms/AI before I start taking courses in Deep Learning, so wanted to gain experience using Battlecode 2019. Is an AI contest like Battlecode too much too soon for a beginner programmer without knowlede of data structures like Maps?To be clear I don't want to compete in Battlecode just to win the prize money, I prefer to use this contest to develop skills that are useful in AI/Machine Learning/ Robotics/Algorithms.
It's harder to grow a large economy for all the same reasons it's harder to grow a large business (percentage-wise) than it is to grow a small one. Sure, there are some economies of scale. But in the end, there are always fixed components to growth that are less dependent on size, and those less elastic components are necessarily more significant for a smaller economy (or company) than for a larger one.

Going back to the original point of my criticism, even if you regard California's growth as merely average, that doesn't explain how that modest growth has resulted in the middle class squeeze. Any loss incurred by the middle class as the result of tax or other government policies pales in comparison to the massive loss of the wage increases that should have accompanied even modest growth. The problem is clear: left to its own devices, the market doesn't distribute growth in anything like a fair (by value actually contributed) manner. Wealth, in and of itself, creates a huge advantage in capturing new growth, and that advantage is nowhere counterbalanced. Money naturally runs uphill until some kind of catastrophe interrupts it.
Järlström didn't claim he was a Professional Engineer (a very specific certification) just an engineer. This case is akin to someone who does wood working in their house (maybe even studied it) calling themselves a carpenter but not a Licensed Carpenter.

Speech can never be a crime "They have uttered the untoward words! Imprison them."
Speech can breach a contract "You agreed not to yell fire in my theater, you owe me damages"
I agree that it won’t help with that but perhaps that isn’t the point. Saving $20-$50 per month can help with situations along the lines of “some uncommon thing has gone wrong and you need $400 to fix it,” for example a car malfunction (because transport is required to get to work, this is urgent)
So in anycase the model had too many degrees of freedom, was not parsimoinous and therefore had a low information criterion. If your model can encode the entire information set, then you arent prediciting you are simply recalling. What a silly article.
Become CEO of Google.
The important distinction here is not whether the speech is good or bad; it's whether we are punishing bad speech that happened in the past or actually preventing speech from happening in the future (which may be good or bad).

The first amendmemt rightly allows punishing many kinds of bad speech after the fact, but places a much higher bar for restraining speech in the future.

Blocking websites or communication apps over harassment is simply unconstitutional unless there is some kind of extreme example (like the domain name itself being invalid speech).
