Languages where indents have semantic meaning tend to prefer spaces. Python style guide [1] explicitly specifies spaces and while Ruby community doesn't have official style guide all their popular unofficial style guides prefer spaces over tabs.

I think the problem is that it's so easy to accidentally mix spaces and tabs that it is more convenient to disable tabs and just use spaces.

This is totally why I get up every morning. We are working on Tinkercad which is a super easy to use CAD tool so that more people can design things for these 3D printing devices. There is a ton of people out there, from small children to research scientists who have ideas that can make the world better and just need a way to express them. Super stuff, thank you for sharing! :-)
Traction, how did you get it?
It feels like being an indie developer is 20% coding and 80% marketing. I've throw my credit card at every social network's advertising system, hit reddit and posted in the appropreate subreddits. Most of my friends are users of my service. The only complaint I have is that if I stop buying ads and running around telling everyone about my service, there will be no new users. Any tips to get organic growth kicking in? Will I be spending more time advertising my services instead of making them better?

I'm thinking lawyers might, by the nature of their profession, provide more value than devs though, since they can keep you out of jail or prevent you from being seriously screwed in a deal, while a dev is mostly just increasing your revenue/profits by extending your software. Also, lawyers are able to provide value within relatively small timeframes (compared to developing something meaningful), which makes high hourly rates more acceptable to clients (as clients are mostly interested in "how much for not going to jail" total amount, not the hourly rate)
Aside from what others have mentioned keep in mind that something being sent to another planet usually has 5-10 year old technology at best. For reference in 2003 Linux 2.4 was the latest stable version.

This is now particularly economical for two reasons, aside from the cost of the fiber to the home itself (either aerial or buried, which is going to cost more for labor/bucket trucks/trenching than for the fiber itself). Why?

1) Inexpensive good quality 24-port 1U switches from Taiwan (Planet.com.tw) with 24 1000Mbps SFP ports, 10gigE uplink.

2) Inexpensive $65 1000BaseLX SFPs

Stevia alone is pretty awful, very bitter aftertaste. But there are some new stevia derivates that aim to remove the bitterness and turn it into an acceptable sugar substitute. Pepsi has developed one, and the Coca-Cola Company, with Cargill, have recently developed Truvia (http://en.wikipedia.org/wiki/Truvia), which is already being used in some of Coca-Cola's beverages. You can buy it in packets for home use. So far, TruVia is the best-tasting artificial sweetener I have come across. Much better than aspartame, sucralose etc. No bitterness to speak of.

Another natural sweetener called erythritol (http://en.wikipedia.org/wiki/Erythritol) is also very good. Unlike stevia, I believe it works on its own, with no modifications required to remove bitterness etc.
Ask HN: How does working without management works for more day-to-day jobs?
Reading about companies like Valve or github without any management, I wonder how other departments like Customer Support or Accounting (anything that is more of a day-to-day job) are organized.

I guess I understand how and why this type of company can success without any structure when it comes to development or design. But how do you get 20 support folks to work their shifts without management or someone how coordinates this.

Maybe anyone around here knows how this is handled at these companies?
Interestingly, there actually exists an Outer Space Treaty. [1] [2] (aka "Treaty on Principles Governing the Activities of States
in the Exploration and Use of Outer Space, including
the Moon and Other Celestial Bodies")

It was initially promulgated by the USA, UK and [then] USSR in 1967, a 100 countries are currently party to it (with a further 26 signatories pending ratification], and it explicitly says, "outer space, including the Moon and other celestial bodies, is not subject to national appropriation by claim of sovereignty, by means of use or occupation, or by any other means".

All this is under the ambit of the United Nations Office for Outer Space Affairs.

Personally, the cynic in me can't help but believe that the USA was an eager initial party to this because they were terrified that the Soviet Union would pip them to the Moon-post.

I disagree. It's "fantastic" as a generic (midi) control panel (similar to the Lemur, for instance Touch OSC or Max/MSP). Of course, you could usually achieve the same thing with an old second-hand Behringer BCF-2000 (or BCR-2000). Bonus: You get motorized faders and real knobs that you can touch.

LinkedIn's recent data breach costed it $1 million
Excellent post. I read every word.

I would go even further. Even though you state that for any person member of humans, there exists someone smarter than person, sometimes you slip into writing as if there is a linear ordering.

The geniuses and prodigies, sure if you project unto one dimension you can find a few people who dominate. Maybe you can find a few such dimensions. But there are vastly more dimensions where they would rank poorly than not. So instead of looking at it down the narrow lens of any one subject, it is best to focus on creating a uniquely useful combination of skills that you dominate on.

And then, why focus on intelligence or comparisons or domination at all? Focusing on things like that can be detrimental. Treadmill wise and also, especially to creating. Ranging from "I know I am super smart enough to do that so why bother?" to "I am not super smart so that is out of my league." Better to focus on results and ideas. You want to do something? Try it or don't. Sometimes being confused can be useful. Creatively speaking.

And then take a step back. It is possible that as you say, the distribution is no longer normal at tail but the range on humans is still a tiny pinpoint. We got things that are vastly dumber than us and it is very certainly possible for an intelligence to dominate us in orders of magnitude.

Why focus on such small change?

I have thought long on this in trying to combat feelings of worthlessness compared to how very much less I have accomplished than my father did at my age. He was one of those genius type people. =(

> "It will belong to us. It will belong to humans."

We haven't found anyone else. Unless and until we do, we're not taking it from anyone. We're just gradually expanding our use of a resource that is currently not in use.
So, here's why that happens.

There are typically two phone-minute charging models: "Calling party pays" (Eurozone, others) and "Both sides pay" (US, Australia(?)).

In a "both sides pay" scenario, each customer pays for their own side of a call. I call your mobile from my mobile, we're each charged a minute per minute.

In a "calling party pays" scenario, the person who calls pays for both sides of the call. You can tell when this is happening by whether there are different rates for calling landlines vs. mobile phones.

The important thing here is what this means for pre-paid services.

In a "calling party pays" situation, a mobile subscriber can continue to make money for the telco _just by leaving their phone turned on_, regardless of whether they can make outbound calls. The inbound caller will still be giving money to the pre-paid caller's telco.

With "both sides pay", the telco of the pre-paid customer receives all revenue up-front; there's no subsequent money to be made because all charges come out of the credit balance of the pre-paid customer. Between that, and revenue recognition rules, it makes sense to expire that credit every 1-2 months because there's no other way to get a revenue stream off that customer.
> the kid tries to resist the officer in some way, it escalates, and when he gets turned around his chest goes down on the table.

The _kid_ tries to resist the _fully grown man_ in _some way_...

What way? If your observation is acute enough to see through the opaque man to tell that it's "his chest [that] goes down on the table", then surely it's good enough to tell us in what way the child tries to resist.

What disturbs me is how ready people are to dismiss this as acceptable. Whether force is warranted or not, whether the minor did something or not, whether he resisted or not, the force is still clearly excessive. A submission hold would be sufficient. And I would expect that the policeman would know how to execute a submission hold. So I can only think that he chose not to, and instead decided to, how do you American's put it, 'open a can of whoop-ass' on the boy.

These days, American schools more resemble prisons than places of learning.

It's interesting that there's some girl berating and trying to stop the videographer from shooting. The part where it gets really shaky she might be physically trying to stop him. It sounds like she's a student. She says "You're recording this and you're not supposed to be recording it" and then calls "teacher!". Is it against the law to shoot video in American schools, now?

Ask HN: Why are the computers aboard Curiosity so puny?
For all the sophisticated equipment on this rover, the computer seems surprisingly underpowered. Surely, they are going for quality of quantity, but these specifications are somewhat lackluster - 256MB of DRAM, 300 MIPS processor. Maybe they just spec'd it out for only what they need?

Anyone have insight into this? I'm sure there is a very good reason for this - I'd just like to know.

C Programming Language Part 3 - Scope
This is why I hate programming
I was watching the Planetfest rebroadcast of Curiosity's landing, and mention was made of there needing to be two operating systems: one to deal with entry and landing, and the other to handle roving and research. The speaker went on to say that both OSes don't fit into RAM at once, so they would have to be swapped over post-landing, and that this would take four days to load from Flash.

Raises the question: why does it take four days to swap an operating system in from Flash, and how does the system go about it while having a path to fall back?

* "Unsafe version control"

* "Git history is a bunch of lies"

These come up time to time. If you need safe Git history, you're supposed to sign your commits with GPG. Git has built-in tools for that. Linux kernel and many other major projects use signed commits. In addition to keeping the repository safe from changes in the history, it will also protect you when your git server gets hacked (where Subversion will fail).

If I read one more blog post that brings this up, I will cry.

What comes to the squash/rebase/rewrite history part, it's a good idea to not commit any revisions that do not build and run to your master branch. If you push a revision that doesn't build, you'll have a harder time doing "git bisect" (you can skip broken builds, though). It's a good idea to squash and rebase before commit to master. Use git merge --no-ff if you want a merge commit in.
of course it can :)

Traction is 100% about persistence. Nobody cares about your code. You need to constantly approach bloggers to write about you, post in forums, online communities and link sharing sites such as this, generate content and optimize your visibility on search engines, and mainly just keep plugging at it until something sticks.

Also, not every service can have organic traction. Some services are just not social / sharable (I would even say most services), and must rely on tried-and-true user acquisition techniques - ads, affiliates and so forth. It's also possible that your service is not of enough interest or use to people who are not friends and family (just putting it out there).

I'm 29 and only started programming a year ago.

What's "worse" is that my father is a computer scientist (who was involved in the industry since the 70s) tried to teach me since I was 6 but I was not interested.

My brother was interested and became a very distinguished developer in his own right (working as a developer since he was 12).

The feeling of 'missing out' / 'starting too late' seems to be ageless. I have experienced it many times through many years and it always prevented me from pursuing my passions.

Some might find it funny that a 18 year old will feel that way but I remember feeling the same thing.

By chance however, I stumbled into programming again but this time it caught me. I was finally enticed enough by it's complexity, its interesting problems to solve and the creative outlet it give me to overcome the debilitation of my fears and 'regrets'.

What I found was that if you love doing something, if you enjoy the learning and the rewards that come with it - you stop worrying about where you are in the great scheme of things.

Perhaps it's my age finally telling me that time is not what's has past or how much you still have left but how you are using it now. Use it to enrich yourself and enjoy it as you see fit.

We are wired to compare ourselves with others. But these days we don't need to be the best hunters to survive and flourish, to get the girl and live happily. We just need to find what makes us happy and enjoy doing it. Doing that will just naturally make us the best we can be.

Typically the reason is often the need for radiation hardening. Operating in space, or on the surface of Mars, outside the radiation shield that is the earth's magnetic field, is a very different, and very harsh, environment for electronics.

Pertinent quote from the above Wikipedia article:

> Due to the extensive development and testing required to produce a radiation-tolerant design of a microelectronic chip, radiation-hardened chips tend to lag behind the cutting-edge of developments.

Paying money for an app from guy who says "pay me $1000/hour or go fuck yourself"

not in a million years...
Locksmiths are sort of a weird case: you can learn to open 95%+ of commercially relevant locks with $100 of tools and less than an hour of training. The biggest reason it costs $150 and not $25 is that your locality makes it illegal to advertise as a locksmith, and illegal to possess locksmithing tools, without certification. There's a nebulous security rationale for this, because apparently normal people can be allowed to own credit cards and compressed air cans but if we allow them to open locks for money as well then they'll burglarize every house in sight.
I started programming 30 years ago when I was in high school.

... Wait for it... . SO WHAT!

Seriously, the thing I love the most about our choice of career is that if you want to be good at it you will be learning for the rest of your life.

I wrote a system last year that processes 3.2 Billion queries a day at peaks of 45k/second and all under 4ms response time. Very little of what I learned in high school about z80 assembly language had much to do with this project. Most of it was exposure to all the things I've worked with for 30 years and some of it was stuff I learned six months ago.

The "learned six months ago" is the part to pay attention to. If you enjoy the challenges placed in front of you and you enjoy learning this is one of the best businesses you can be in. If you want to park yourself at a desk and do minimal work and/or new learning then try a different field. There are plenty of fields you can master quickly and not have to learn much for the next 20 years.

When you start is not as important as your passion and dedication. My father and I were talking the other day and he told me how he was so impressed with how smart I am (this coming from my dad who at 71 learned to write in Php lol). I told him I'm actually pretty average, the difference is persistance. I recently heard a claim that Albert Einstein said "It's not that I'm so smart, it's just that I stay with problems longer.." I'm not sure if he said it or not but it is exactly how I feel. It's not about what year you started to program, it's about staying with problems longer and working them out and learning along the way.

Enjoy the ride.. I know I have and it's just barely started.. ;-)
