The point is to allow untrusted clients (browser/mobile) to run (safe/predictable) queries against your database without the need for "backend/api" as a middle layer because nowadays most of the business logic is mostly on the frontend and it needs a way to get to the database.

It's not necessarily useful if you have trusted code running on your servers, it should just connect to the database. But if this works for you ... why not.

(At least that's how i think of it, others may use it in different ways)
I feel your pain. If only we could harness programmer frustration into energy, we could stop burning fossil fuel. And don't get me wrong, I have my own long list of gripes with Microsoft and Visual Studio, they're nowhere near perfect.

The problem at my current job involves a metric crapton of CMake files that don't have a clear maintainer (big company, anyone forced to touch those files just does the minimum required to get the desired effect) and it's a general hassle to understand what exactly the project settings will be for any given directory. I find the CMake syntax so confusing that I switched to Meson as build system for my personal projects; it's not ideal, but I find it easier to digest.

Anyway, I understand your point of view. Have a nice weekend.
Thanks very much, that's incredibly helpful!

I will be redoing the tutorial to make it. That's a good idea about asking the player to drag the first piece, instead of just showing an animation.

I've had around 1,000 people play the game. My favorite feedback so far from was a guy who really enjoyed the game, so he shared it with his father and sister, and now his whole family are playing. But yeah, I also got a lot of "it's cool", which I don't pay too much attention to.

For analytics, I'm using Fabric Answers and Firebase Analytics. Here are some of the stats from iOS: https://imgur.com/a/8zz15

Those retention numbers look really bad, but I can't say I'm surprised. I'm also pretty happy that I made $50 from IAPs, because I've never got this far before.

Maybe my next project should be an RPG or "farming" game that you keep coming back to every day.

I agree that my monetization strategy is not great, but I don't want to advantage of people with purchases for "bags of coins" and stuff like that. But maybe that's the only way to get ahead?

I can understand that your game with millions of DAU might not be able to support a game studio with salaried employees, but if I extrapolate my own numbers then millions of users would be bringing in tons of money for a solo developer. That would be something like $60k USD, which I wouldn't complain about!
"I have a partner" is just one way to tell someone their attention is unwanted.

I agree. Been there, done that. Not fun.
The point is to expose it to the web. It's primary role is to be accessed by browsers/mobile apps, not code running in the backend
If you talk about the general idea of an append-only distributed database with no central point of control, I agree with you.

However the proof-of-work/auto-adjusting-difficulty method of asserting truth still seems horrible to me from a technical perspective.

Politically, I don't want to live in a world where this principle catches on and an ever-growing % of energy production would be spend on solving meaningless math problems.
Yes, for better or worse ugly is definitely a 2nd-order predictor of success.

I guess "ugly" is a fair assessment of the 8086 at the time. Certainly the 68000 was a much cleaner and orthogonal architecture. On the other hand, I'd rate the 8086 at least as good as if not better than other contemporary microprocessors such as the Z-80 and 6502. The 6809 was sweet but a 16 bit address space rooted it in the previous direction and the 68000 make it clear that the 6809 wasn't in Motorola's future plans. Sure, had IBM chosen the 6809 there surely would have been a compatible follow-on but I can't imagine even the stanchest IBMer to have that kind of hubris.

But calling MS-DOS ugly at the time would have been unfair. It was as capable as any other microcomputer OS at the time in the home computer space. It was widely proclaimed to be a rip-off of CP/M so we might take that as a compliment and if you look at TRS-DOS, Apple DOS or whatever PET's used it was just fine. It'd be unrealistic to suggest and mini or mainframe OS was an option and Unix just wasn't there yet. If IBM had given Microsoft more lead time they might have went with Xenix which they did have out in 1981 for the Z-8001. I'm not so sure IBM would have been interested, though, as they wouldn't have an exclusive license to the OS.

Not to mention that the overhead of the operating system was an important consideration. The machines didn't have much capacity to waste and whatever you picked it still had to perform well on a system with only floppy drives. Maybe that in itself doesn't rule out Unix but it sure cramps the design space.

In both cases, CPU and OS, the ugliness really took off with backward compatibility to maintain. The 80286 was already being designed so it drove that deeper into the weeds and there was no way of bypassing MS-DOS compatibility once it anchored the marketplace. The only way forward was to improve the OS while keeping MS-DOS programs running and the whole OS/2 debacle only helped to delay that upward path.

I mean, fair enough to say "ugly won" but some consideration should be given to the lay of the land when these long-term trends were set in motion.
Yes, but my point was more about the Soviet program of continuous improvement associated with it. According to your link, they stopped the assembly line at the collapse of the USSR. It doesn't prevent them from upgrading the existing airframes like for the B-52, but it isn't a true rolling replacements/improvements program anymore like the F/A-18 [almost] is.

Edit: Maybe the F-104 starfighter program would be another good example.

> Jack Dolance, an attorney for the Williams’ family, said that how and why Mr. Mader was fired “is pretty clear evidence of their policy and that the way they feel [the shooting of Mr. Williams] should have been handled. Not only do they think he should have been shot and killed, but shot and killed more quickly. "

What in reading between the lines for why they acted the way they did is money. My guess is the city administration believes a shot and possibly dead police officer would cost them x monies and that a black man holding a gun doesn't have much of a recourse especially if he is dead.
I have no idea how leaking highly classified cyberwar toolkit helps that cause.

Ask HN: Are the ideas from Jeff Bezos philanthropy tweet summarized?
Ask HN: What's your dream work schedule and why?
Mine is:

From 6:15am to 9:00am, work alone at home.

Get ready and 15 minutes walk/cycle to an office.

From 9:30am to 12:45pm, team work.

Wednesday and Friday work from home only. 6h/day (3h on Friday), 27h/week.

Why? I'm only productive during mornings. Early morning for deep work and the rest of the morning for team work. Free afternoons and long weekends (starting at 9h friday) for a balanced life.
People die without violating any law and in fact without any reason at the hands of the modern day gestapo we jokingly call a police force. The only thing that needs to change is prosecuting police officers who shoot civilians without good cause. Instead the system protects them then nut bars get angry for the right reasons but at the wrong people.

Then we end up with not only dead civilians but also dead cops because some angry individual decided to ambush and kill the nearest representative of the boys in blue.

This like as not kills decent people who wanted to help their community and as a nice side effect makes cops more fearful and therefore MORE likely to shoot more innocent people which riles up the populace and makes them more likely to shoot cops.

The only way to short circuit this bad day is for federal authorities to punish the cops that communities wont. Unfortunately with the current administration that is laughably unlikely. Up next a bunch more dead people.
Ask HN: How do you manage your time with multiple projects?
This question is not about multitasking (doing multiple things at the same time). This is question is more of a framework for short-term and long-term learning.

I will explain this with my situation:

I am working on a personal project (say P1) that I would like to ship soon (may be in 2 months). I also have few more ideas of new projects that I would like to work on sooner. I would also like consistently add value to P1 in long term.

Additionally, I have curiosity about information retrieval (currently reading a book and plan to start an open-source project to learn how the fundamentals work).

To add more to this, I have a full-time work to do.

As you could see, there are so many things that I do (at least I feel) and so many other things that I plan to do. I try to manage all of this work with Asana tasks, but still I feel that I could be more effective.
I look for inspiration and see people like Elon Musk and wonder how do they manage to run multibillionaire companies? We all have 24 hours in a day.

So my questions are

1. How you manage multiple projects efficiently?

2. This is an art and I would love to learn this skill

3. What resources (books, courses, talks, your experience) you would recommend to learn and gain this art?

Thanks for reading this far, appreciate your time spent
You mistake 2way data binding with ui decomposition and right view model structure, if you have those problems.
With the right view models everything becomes is easy and simple, but you do not get there right away, it's hard to learn, and no framework will bring you there.
This is due to ppl spending way to much time chasing frameworks in vogue, than learn to architect applications.

Emacs Lisp is much less performant than a modern Javascript implementation. I don't see how choosing JS as the extension language raises any serious performance issues.

Extension quality is a bit subjective, sure. But if you are going to claim that emacs extensions are of higher quality because they're written in a more obscure language, then you should give evidence. That is not my experience.

Yeah the proof of work is probably the less elegant aspect of it all, I can agree with that. But theoretically you could replace by any other function that's difficult to compute but easy to verify. Maybe it's just a solution in search for a problem.

Sorry if this is obvious but I went to focus on revenue per user per year.

In other words, how much is it worth to fight the perception that gmail is somehow less secure than office 365 because ads (others have pointed out Google apps for business users don't see ads in their work gmail).

I somehow doubt that gmail ads are worth even remotely close to $120 (12 months * $10 per month) per user per year.

In other news: How much is a user worth per year to Google? Assuming not all users are the same, is there a way to predict his much revenue a user can bring for Google?

Multiple people said he was not reaching for a gun, including the other officer on the scene. "He's not reaching for it" can be heard in the video, and Castile himself says, "I'm not..." before being riddled with bullets, and the last thing he said was "I wasn't reaching for it".

Nobody thought he was reaching for a gun, except (maybe) the dangerously unhinged officer who shot him.

It's also wishful thinking. If IBM had controlled that, there wouldn't have been a big enough ecosystem around the PC platform for it to become the winner. IBM also tried to grab this back with PS/2 and OS/2 which also failed.

It's interesting to compare this to another article linked here about the downfall of the TI home computers. Apparently TI understood the value of software to the point where they threatened to sue unlicensed software vendors, which pretty much guaranteed that those vendors chose to write software for other platforms. Perhaps they would have had a better chance if they had opened up their platform?

PhoneRescue 3.3.0 Crack and Serial Key Download [Working]
I did give that opportunity.
Yanez fucked up, hard. He was clearly on edge and nervous from the start, put himself in a bad position, and the verbal commands he gave were utterly atrocious.

He asked for proof of insurance and ID, and then once Mr. Castile informed him of his weapons permit, Yanez said "don’t pull it out". However, to someone who isn't intending on pulling out his concealed-carry weapon, "don't pull it out" does not adequately and unambiguously signal "stop moving". Mr. Castile was obeying the command to show his ID and also had acknowledged the order not to pull out his gun. Yanez did not even entertain the possibility that Castile might not be reaching for a gun -- and the phraseology Yanez used is indicative of that. Had Yanez wanted Castile to stop moving altogether, he should have issued an unambiguous command to that effect; such as "stop moving" or "hands on the dashboard" or "put your hands out the window now".

Yanez got himself all worked up and panicked before even making contact with the people in the car, issued verbal commands that were obeyed to the letter, shot up a compliant person, and then gave weird excuses about the smell of marijuana during questioning. Yes, someone in Castile's position could have stopped moving altogether when hearing "don't pull it out", but it really shouldn't be up to people stopped by police to try to reverse-engineer an officer's intentions and de-escalate the situation to avoid being shot by a nervous policeman. Obeying commands should be sufficient to not get shot up.
The Strength of Us Versus Them
My dream schedule is no schedule. Just do things when the mood strikes.
I teach a Quantitative Methods course and in it, I have students read through the Guesstimation book by Weinstein and Adams (listed on that wiki page). There is also a second volume.

They do 11 blog entries each on modifying a question from each chapter and then computing it out.

I also have them watch TED talks and come up with guesstimation critiques of the talks, also in the form of 11 blog entries.

These are highly effective exercises. I recommend doing something similar. If you can, find some others who are interested in doing the same. Reading each other's questions and answers is very valuable in detecting mistakes and comparing your own technique to theirs.

Fundamentally, you just have to do it.

The mental facts needed to memorize are surprisingly minimal. The Guesstimation book lists some good suggested ones. Often you will find you already have some sense of a number. By taking reasonable boundaries on either end of the plausible range and then taking the geometric mean, you can get a decent approximation.

The mental math is also fairly minimal. It just requires two digit arithmetic for the most part along with being comfortable with powers of 10. There are books on mental math, but I think practice is sufficient for two digits: http://arithmetic.zetamac.com

World's first railless train? China unveils hybrid self-driving electric vehicle
Normal air conditioners produce a lot of heat, which is usually ventilated outside. That's more difficult to achieve deep underground.

According to Wikipedia, it's a groundwater based cooling system.

How much would it cost to add regenerative braking to the cars?

And instead of ventilation shafts you would probably need active heat pumps

The tube did not have powered A/C until fairly recently - it was built with ambient air ventilation only.
That's a good question and the answer is that both the sun and the number 15 are concepts created by the mind because creating concepts has great survival value. You are conscious of these concepts. "Consciousness" itself is also a concept you are conscious of. We tend to confuse the map with the territory - perhaps because believing the reality of the map makes us more real and gives a sense of control over things - I wouldn't know. What I am convinced of is that consciousness (and I'm not referring to the concept of it) is not a product of the mind, but vice versa.
That's the point of using deep learning here. Of course you can't make up the missing information, but by training the model with a lot of samples, it should eventually reach a point where it produces the most likely original information.

It works quite well on images: https://github.com/alexjc/neural-enhance
For one thing I'm surprised they're not using regenerative brakes. It sure will cost some of the profit but refurbishing the trains with these will cut somewhat on that 80% of heat
Regenerative braking is already widespread, as mentioned in the article. Unfortunately some of the stock is very old.
I've always been more on the materialist side. Reading this, I finally managed to put a finger on something that's been bothering me.

Our brain knows it is conscious.
If consciousness is an immaterial phenomenon, emerging from those processes, how can the brain know it is conscious? What way could a brain possibly have to measure consciousness? When I refer to brain, i mean the physical, scientifically measurable computing system. Several conclusions are possible:

1) The brain is conscious and can accurately measure that it is conscious. -> we should then also be able to measure this consciousness, if we figure out how the brain does. (wouldn't we have found something already?)

2) The brain is conscious and accurately guessed it is conscious. -> problem: why would the brain guess this, especially about something it can not measure?

3) The brain does not produce consciousness but thinks it does. -> Just as the metaphysical zombie, being molecule for molecule identical would assert it is conscious. (but now we're denying consciousness exists, see arguments about eliminativism in the original post)

Any thoughts?
This is a much better and more thorough read.
