Much like the biological environment, the economic environment isn’t static.

This is the one thing that "evolution debunkers" consistently get wrong. So many of their arguments are predicated on a static fitness function, when such a concept is clearly nonsensical. (And so far, not a single one of them has ever been able to even comprehend this enough to formulate an actual response to this observation.)

I wonder if there's something analogous that goes on with some people's startup debunking?

I'm one to claim that Signal isn't for me on a regular basis. Can't find the link right now, but I confessed a good while ago that I somehow hold Signal to another standard.

Currently I'm backing off, trying to reduce my critical comments. It's a great project, and it probably should be more widely adopted.

For me? I feel this is a weird uncanny valley effect for IM solutions. It's not ugly as shit, but it's also not quite there yet and that leads me to leash out at Signal every now and then (keywords for me: lacking federation, phone number is a crappy _mandatory_ identity).

Now, that's really not fair. I don't complain about WhatsApp as much as I complain about Signal. It's a double standard and I understand that - but can't help myself here.
Last job was for an ~500 person Ad Agency. I worked mostly solo on all of my projects. There was other developers within the company, but they were treated as completely different departments -- guessing on purpose. The company as a whole was overly political. Lots of meetings, not a lot of actual work getting done. Plenty of people I know of that literally did nothing. In the 2 years I worked there I was never able to figure out who my supervisor was. After quitting, I was finally able to figure out who it was -- someone I never met, and didn't even know their name. I was overpaid and overqualified. Could have easily asked for a significant raise, and could have gotten away with doing significantly less work at the same time. Ultimately I quit because the work was boring and I spent too much time in meetings. Took a pay cut, but I couldn't be happier with the new job.
The party machines play games to try and purge the other side's voters to bias the results in their favor. This gets woven into the 10 year redistricting cycle as they scheme to gerrymander districts to further dilute the opposing party's constituents. Everyone in office is a beneficiary of this system so they won't take measures to fix it.
Yeah, in a similar situation right now and I find the DLL thing is relatively unknown and incredibly powerful if used well. Recently this 'robotics' evangelist keeps trying to rope us into spending a few mil on his automation and I keep showing him up by automating the same stuff right out of Excel for little to nothing.
If you want to get a taste of the benefits of tmux without having to learn anything new, I recommend using iTerm and setting up an alias for

'ssh [your server] -t "tmux -CC attach || tmux -CC"'

Just running that command will connect to your server and attach to an existing tmux session, or create a new one if needed, and make use of iTerm's tmux integration, so you can use the standard macOS keyboard commands (or the UI) to do things like switch tabs, make new tabs, close them, make new windows, etc. all using tmux and a single ssh connection. You can press 'esc' in the command window to detach from your session and when you return (just using that alias) all your work is just as you left it.
I've also personally encountered 24 for C. That's not the problem with (' '*13) here, though — C doesn't mandate ASCII.
> The biggest complaint I regularly see about it is that people are used to the screen keybindings.

That's my problem with Tmux. Ctrl-a,d is already burned into muscle memory, and for my applications Screen is "good enough".
So you have two attack vectors, the OS host and the client application; why is it bad to secure the client? It doesn't ADD any attack vectors. What is the point in saying "Let's not secure the client software until the OS is secured"? It isn't like these are the same people working on the problem; Moxie isn't going to suddenly start working on securing iOS if he isn't working on OWS.
Looks like a copy of Letris, to me: http://www.letris.com
Before people waste time with these calculations can you explain how they relate to signals on a wire? You have mixed up some phenomena while reading up on electronics.
It's an order of magnitude higher than a laser sail which is part of NASA projects for some missions. So that already makes 1.2 N/MW pretty good.

Also, remember that the EM drive doesn't need to carry combustible fuel to work, it could do with a fusion reactor in the future and that would save a lot of mass in the spaceship.
Performance is poor on my older laptop. Maybe I'm getting to the point where web devs should leave me in the dust, but, it's also a shame to waste resources on newer systems. I suspect the problem is that it's built on React, which struggles with large data sets.

If the team is reading this, I'd bring up a point made on the Netflix dev blog: the key to great React perf is doing the expensive stuff outside of React. Do it low-level, stitch it in with lifecycle callbacks. You can end up keeping most of your code in React's world, while fixing most of the performance problem.
Turn your Xbox controller into an instrument
I love this type of science. It's completely, totally impossible... until we learn about how it works and the mechanics behind it. Maybe this type of drive just previews a new discovery?
I'll grant you it gives you more and different press. I won't grant you that press coverage matters very much when it comes to fundraising and recruiting. It matters some, but the delta created by a founder's gender multiplied by the general small impact of press is really not moving the "get off the ground" needle.

If it did, you'd see wildly variable outcomes indexed by founder gender.

I spent a little time evaluation some form of quantum resonant enhancement of pair production as an explanation, but not enough to make any claims. The pilot wave / ether theories suggested in the conclusion seem highly unlikely. I'm also still holding out for weird RF coupling - those Q factors are so high.
Thanks for this awesome comment. Agree with everything you said. This could probably make a nice blog post. :)
That is how it is done.
"we also have to imagine that the bank-grade vault door to the shed costs about the same as a regular door."

I admit defeat. Two extremely strong back to back arguments, both very persuasive and well written.

I see we have common ground on the toning down the security language. That specific aspect of the issue triggered me a bit into a general, eventually proven somewhat wrong, rant.

Have a pleasant day!
The narcissism of Donald Trump's candidacy
> Figure out how much folks would be willing to pay for a solution to the problem.

I agree with other people about being smug. There are certain types of business where the business model is not obvious at least in the beginning, but you know that there's some value that you can potentially monetize.

In these cases, would you be smug like that and just give up trying and work on obvious ideas? Or would you try? It's not everyone's cup of tea, but I totally respect anyone who does that.

A lot of world-changing companies were born that way. Including Google and Facebook.
But Google was the first mover with its way of sorting the data from web pages, by building PageRank.

I also don't get your point about how lame Xamarin apps look. Xamarin apps use native layout components (could be wrapped with lowest common denominator abstractions in case of Xamarin.Forms, but it's optional), so they're 100% capable of looking the same way your native app would.
Does anyone know the color scheme used in the examples? It is very nice.

You can't. People that are receptive to the politics of fear are that way because of brain structure; they simply are unable to respond to reasoned arguments.

All those problems had already been solved prior to FB. MySpace is the obvious example, but there was also Friendster, and a few others. I'm almost certain that FB's success primarily hinged on its exclusivity (Ivy League & a few elite schools -> colleges -> gen pop) and not necessarily on what it did.
I had a set up of my old computer with xubuntu for my mum for 1.5 years and had to learn that Linux is just not stable enough in the long run if installed for a novice user or as a "parent PC". Don't be naive here; even automatic updates will too often either break something or confuse users unfamiliar with computers. And you will need to be around to fix it or they won't be able to use that computer anymore.

I ended up buying her a second-hand MacMini for 110€ more than 2 years ago. Old enough that it still was a PowerPC version. It still works very well, never needed to fix something, it is fast enough for her use cases (e-mail, digital camera, some internet surfing), and she loves it. If things get messed up on OS X they do that in a "user friendly" way, and she (before being mostly annoyed by computers) has started to become quite proud if she can fix such minor issues by herself, or with only little guidance. I'd say she acquired some general computer literacy through using OS X, but not through using either Linux or Windows. She now likes Steve Jobs.
A good time to TLS fingerprint your connections and get an idea of which client is probing your server.

Probers might have their own unique TLS fingerprint.

i think redhat's ceylon strikes my personal sweet spot between java and scala, but kotlin is a great language too.
For most results like this, it turns out to be an experimental mistake. That's how the phrase "extraordinary claims require extraordinary proof" came about.
So, you're saying that capacitors store electrons?!

Debunking this particular conception was the whole point of my capacitor article http://amasci.com/emotor/cap1.html

Capacitors "store" electrons, like springs "store" steel, or rubber bands "store" rubber. A charged capacitor has exactly the same number of electrons as an "uncharged" capacitor.

When "charging" a capacitor, charge is forced into one terminal, and exactly equal charge comes out of the other terminal. No electrons build up inside, nor are placed into it. They've just been moved around inside, same as the steel spring, or the spherical tank in the water analogy.

What then do capacitors store? EXACTLY! That's the questions that students should be asking. They won't think to ask it, if they've been taught that capacitors are like buckets full of electrons. Well, what does a steel spring store? Or a stretched rubber band? KG of steel or rubber? Nope. Capacitors store joules, not coulombs.

The above concepts open the way to unifying several ideas: capacitors store charge in the same way that inductors store charge! In both components, energy is stored, as e-fields in the case of capacitors, b-fields in the case of conductors.
You add exponential falloff if the server returns anything but a 200.
It would be useful once you're in orbit, even deep in gravity wells, if you're patient. For example, a geosynchronous satellite with a drive like this could be launched on a rocket just big enough to get it to low-Earth orbit, and then it could gradually take itself the rest of the way. But it won't be replacing traditional rockets for that initial launch unless it's possible to increase its thrust by many orders of magnitude, and that initial launch is really the hardest part of doing space.
I have (had?) one client that every week or the other would come back for a Windows reinstall. Since he only browsed the internet and did not use any particular software, I installed Linux Mint and he never came back! I lost that steady 'revenue' though.
So you're saying it's possible then?

And yes, I mean after I pay SpaceX a large sum of money to get me up into orbit. Hovering with these would definitely be a bit overbudget. I guess my question is whether a few micronewtons per kw adds up to a viable means to travel in space, or is it more like just enough to keep the satellite in orbit indefinitely?
No. I'm glad to see extremely privileged well connected individuals getting fair treatment and not special treatment like they may have gotten all their lives.
No, but we currently do not know of/have any other medium that serves that particular niche purpose.
I always get my best "aha"s when I've found the source of an OOM in Java.
I'd imagine if it is real we'd be able to increase the effieciemcy. It seems unlikely we stumbled onto the optimal design.
Well, it's kind of the point. Kotlin is supposed to be light weight and easy. Besides, using Scala for Android, while possible, is cumbersome. Kotlin wins this one hands down.
The Unix Philosophy and Elixir as an Alternative to Go
If you're generating multi-MW in space, you have to do something about all that heat anyway so I'm not sure this is an improvement over an ion drive.

That said, yes, the important thing is that this potentially indicates new science, which is exciting. When we understand it, we can likely improve the efficiency greatly. Assuming the effect is real.
>> Twitter isn't censored similarly to FB.

All you have to do to confirm this is to visit their homepage and see all the left wing political ideology on it day in and day out.

I haven't seen anything on the Clinton email saga that has dragged on for months now and not a peep on the home page about the rising costs of the ACA premiums. Nope, just love and happiness about having the first female president. Besides that, it was a constant stream of Trump hit pieces from traditional Liberal newspapers and media outlets. It's like they didn't even try to be objective.

If you want to make your platform about public discussion, then maybe you aught to give a slightly more balanced view then the completely slanted, partisan garbage you post on your homepage. It might just give the appearance that you see things in a slightly more objective light.
Twitter is a great medium for it, since it's public by default.

It's the easiest way for a random person to hold their own press conference. People can easily ask short questions, and get short answers. All from their phone
Nothing about Twitter is essential and Twitter is highly filtered. Twitter actively censors opinions and trends it doesn't like. Over the summer, #DNCLeaks trended hard, only to get removed and replaced by a typoed tag that killed its discussion and momentum. The same thing happens, or trending tags get outright removed, time and again with topics related to recent Wikileaks. This censorship happens far too frequently to certain topics to be "glitches" and it always "coincidentally" favors Twitter's political worldview.

Twitter also very selectively enforces rules about what it judges as hate speech and abuse. Certain people can repeatedly tweet "kill all police", or advocate jihad, or advocate violence towards those who support a particular political candidate, but the moment anyone does even a fraction of the same towards any group that Twitter is in bed with, that person gets shadow banned or permabanned. Note: I'm not advocating hate speech, merely pointing out that Twitter allows it more often than not when it aligns with their politics.

Twitter had a chance to be a platform for open discussion, but its brownshirt employees chose to make it a censorship shithole. Never-turned-a-profit Twitter can go fuck itself – it's not essential and highly filtered.

1. start tmux

2. in the first shell you get run:

Permanentize it by changing tmux.conf :)
Wouldn't really help to test it in space unless you can do a better job in space of controlling error than on the Earth. It seems unlikely you'd be able to control for error better when you don't even have physical access to the experiment item. There are myriad of forces acting on objects in orbit, even interplanetary. Remember the Pioneer anomaly?

Earning Rs 21,000/mo even in 2nd-tier cities are not uncommon. Your local small nookad shop (mom & pop shop) can easily clear that in one month. And most of them are not in system. So guess who just had their saving (hoarding? lol) evaporated ?

Those who have too much money, has money to hire tax experts. So IDK this really looks like anus-f__king at scale.
Obviously this is a complex issue, but in general I've found introspective people are the saddest. People that live in the moment are often the happiest.

Show HN: I'm 17 and I created an iOS app to hide one photo within another
Ask HN: Better code readability/reviewability
I'm in a situation where several nested functions are used and each of these functions are present in different files (which are in different directories). (I'm sure there's legitimate reason for modularizing code to such an extent).

I'm having trouble reading the code and being able to understand what exactly is happening.

Is there a tool that would comment function calls and replace them with the function body instead so that I can read it better? Also, would it be able to do this on-demand.

For e.g., in ST3, I could call a function that would find the definition of the function in my project and replace it in my file and does not do so for calls made in the replaced function body until I ask it to?

In my context, this is about Javascript, but this is a language-agnostic question.

Alternate question: How the heck do you deal with situations like this?
Here is what I have seen happen and work quite effectively.

- Find a bunch of investors (that is anyone with lots of disposable cash)

- Befriend them. Use the 'How to Win Friends and Influence People' techniques on them.

- Come up with any idea, doesn't matter what it is at that point, could be "Uber For Dogs" or "Bitcoin Microloans for Clowns" ...

- Get the cash for the startup. Rent an office. Put CEO on your title. Enjoy playing CEO for 5 years.

- Rinse, repeat.

- In the process make sure to go to every single meetup, and conference and hand out business cards with your title on it as "CEO"

- As soon as any new framework comes around, re-write everything in it. Then write a blog post "We switched from X to Y". Convince said investors that this is a crucially important / strategic priority if they start questioning your methods.

- After blog is written add title "author" next to "CEO".
Yes I like that you can choose whatever name you want, but ask your family members or old friends from school how they use Facebook. Being enable to find old friends and connect with far relatives is a huge reason for why Facebook is so popular. I am having a hard time time figuring out how to solve this problem if there aren't any constraints, culture or expectations for using real names. Maybe it's just a matter if time. Online aliases is more second nature to the coming generations. And still, the group and chat thing is very important imho. That's why I asked about XMPP. Would love if we could get a modern chat system as widely and universally used as email.

Hi! I am will join JetBrains in a week to work on new projects with kotlin and vert.x, but have only experience in Akka. Can you point any major issues that you have with vert.x + kotlin?
Yes, there is a transfer of electrons from one place to another. It's not to the thing that does work, but through the thing that does work.

With a battery (DC/direct current), there's a surplus of electrons available at the negative end, a deficit at the positive end. The electrons flow through a circuit (from - to +) to perform work.

With AC/alternating current, the electrons flow in one direction, then the reverse direction several times per second. The purpose of this is to push energy further down transmission lines with less loss. Pushing DC from a plant to everyone's houses is very lossy.

Do electrons have mass? Yes. Does the circuit or device increase in mass when current is involved? No. You're actually not introducing additional electrons into the circuitry. The conductors and semiconductors already have electrons on the outsides of their atoms. We introduced an electron at one end, it hops onto an atom, pushing an existing electron over to the next atom and so on. It's the movement that produces "energy" and allows work to be performed.

Strictly speaking, you can hold extra electrons for short periods of time in capacitors, but the mass is so small as to be negligible.
