As someone who's been there done that: throttling yourself a little bit is a lot more productive in the long-term.

I used to work to the point of exhaustion. Now I work to a clock I've come up with empirically. This means that instead of having bursts of super productivity followed by weeks/months of tiredness or simple "Meh, that's not interesting" I can trod along, putting one foot in front of the next, with a consistent pace. Day in, day out. You might outsprint me today, but I will be there when you're tired, and I will be walking at the same pace I am now.

I am an orc. I do not stop. I do not tire. I just go. Forever. At a constant pace. I will outplod you.

Persistence is humanity greatest natural asset next to intelligence. Use it. We are very bad sprinters.

A Developer Laptop.

Think 'Macbook Air' for developers (open-source devs, .NET guys won't benefit much from this) installed with an operating system without all the usual bloatware.

Don't get me wrong the Macbook Air is a great machine, but it obviously has too much 'Apple stuff' on it that I don't use very much at all.

Officemates told me that the closest to a great developer laptop is the Dellbook XPS13.
Look a little closer - It's not about saving bytes. I ended up coming up something very similar for my projects and it made a notable difference in defect rate.

- Removes the need for positional arguments for constructor injection, so you only have to list your dependencies once. This one seems minor but can be a major frustration and a source of bugs when working with lots of services.

- Moves actions out of the scope and onto the controller itself, where they belong.

- Provides a clean template structure for other project members to work off that guides you to nicely structured and properly separated code (i.e. Watches in one section). This seems minor, but when you're working with multiple junior developers it starts to become a big deal very quickly.

You can do all this without using a third party project, but if you're new to Angular this is a nice bootstrap and helps guide you towards a solution that avoids a lot of warts in the framework.

If I'm working on something interesting I can do 8, 10, even 12 hours of coding without being aware of the time passing; but that's not the point, we're talking of averages here.

Also, some people in 2 hours can obtain the same results of me doing 8 hours of work - that's about quality, so the "woking-harder" it's not a valid argument: the real problem is "working focused"

Igor Knots and the Magonda Maze.

A mobile maze game inspired by Traffic Jam and/or Unblock me. Instead of moving items with your finger, you move a character (Igor Knots) and he must push items out of his way to clear the maze.

The game is on the Google Play Store, the Amazon App Store, and the Nook App Store. I also have a version that works on my iPhone / iPad, but never got around to uploading it to the Apple App Store. I also have the engine working in a browser.

The game got very little traction; but I never did anything to push it. The game comes with 50 levels, but I have an additional 50 designed.

I always wanted to expand the game to include more challenges and types of obstacles. But, I moved on to other things.

It was built w/ Flash/AIR.

I am unable to code completely immersed for more than 50 minutes at a time.
I answered 6-8 hours, although its rare they are adjacent hours of productivity. I am a student though, which may make me a little off-topic for this question, but it is time spent researching, designing, and implementing complex physical models in C++, Python, and/or Matlab (I'm a physicist, computational).

As I am a student... The hours can be very weird. I can walk around my room aimlessly, repeatedly, not capable of doing a single thing for entire hours. But then I sit down at my desk and churn out a few hundred lines of code and write up a report that uses the results of that code. "In-the-zone" can be anything from 3 hours to 6 consecutively, and what triggers it I do not know.

Some of my compatriots feel the need to fool themselves into working 12+ hours a day on their assorted homework/code-work... I try not to do this, and generally I'm very low-stress, because I know when I need to be I crank out pages upon pages of (hopefully high quality) empirical work (assuming I have the data). It's much less frazzling than "omg I can't see my friends or chill for even an hour for coffee... Because I have an exam on Monday". An hour never killed anyone :D

I have had terrible luck with Freelancer.com as well. One and done for me. In fact, the majority of freelancing sites miss the mark on making developers interest top priority as well as what they are supposed to do as the curator of a freelance site - to ensure projects are completed successfully.

Gun.io (http://www.gun.io) has been the only freelancing site that take that extra step to ensure that both sides are satisfied.

Sorry, to hear about your awful experience with Freeelancer. :(

Novel lensmaking technique is combined with 3d printed parts to make microscope addition for smartphone at a cost of less than £1, is presumably the information they were trying to garble.
As soon as I realized this, it actually became quite helpful.

Saying something is "easy" or "obvious" is useful! It may demotivate if done poorly. However with a proper teaching approach it also signals what SHOULD be obvious. If it's not obvious to you yet, it's important to learn and understand why not, and eventually it should become obvious.
I've never taken a math course that didn't contain some overlap. But you simply can't realistically teach everything from every prerequisite in every class. There may always be some students who snuck through a prerequisite without learning or retaining the info. That's what office hours are for.
Something like this happens to me too.

I have a week where I get massive work done, then 2-4 come, where I can't get up to do anything at all.
I was trying to think of what in software is the equivilent as a 'rivet'. Something small, with a near singular purpose, one who's design has changed relatively little in decades. The only thing I could argue we have in software engineering is perhaps machine operands. For example, just about every processor will have a register and can a operand that will increment that register by one.

The result of this is that most software projects are as complex as the most advanced 'real engineered' projects. As software engineers we design whole "space shuttles" in a month. The 'buggyness' of software engineering compared to 'real engineering' is the manifestation of the complexity of what software engineering does. The tools and processes of 'real engineer' are completely ill-adapted to the rapid development of the massive levels of complexity that is software.

However, there are certain projects where a developer examines every instruction, at the detail that the 'real engineering' principles can help, however, the tools at the forefront in software engineering enable the addition of billions of washers to billions of rivets in days if not hours of design.

Is this a result of the success of the 'old blogosphere' and mirroring the challenges of monetization so many tech companies are challenged by.

1. build an audience
2. start monetising
3. quit your job
4. drive more audience and try to monetise

Quickly, you end up serving the monetisation and the soft money that goes to influential bloggers to say nice things. It's sad, but unfortunately not the first time an industry/content/company has lost it's core success and function as a result of the need to pay the bills.

How to overcome this and stay independent? That's the exciting challenge!

Ask HN: Did you have a mentor? Have you ever mentored someone?
I'm 23 and just joined the software industry. I feel like mentorship is something that's missing from my life, and it would benefit me both as a programmer and person in general if I could have a mentor-student relationship with someone experienced that I respected.

I wanted to know:

- Did you have a mentor at any point in your life (doesn't have to be programming related)?

- Do you feel like it was central to where you are now?

- How did it happen, or how did you meet them? Did you approach them and ask them to mentor you, or did it happen more by accident?

- If you've ever mentored someone, do you think it was worth your time? How would you feel if someone you didn't know very well approached you about this?

Thanks for reading.
Hmmm, one problem I see with this, at least for us open source mortals, is that all this rigor sits atop a festering pile of C, that is, the GCC (the GNAT Ada compiler in it)....

I'd love to pick your brain on something. My 5th grade daughter has math anxiety, picked up believe it or not in 2nd grade. As far as I can tell, her actual ability is average or slightly above. But her self-esteem is on the line for every problem, so she won't relax long enough to actually think ... she grasps for the fastest "formula" from rote memory, and if that isn't right, she is distressed.

I need some insightful advice on how to help her out of this mindset. I've googled and looked at books, but there's a lot of regurgitated crap out there blocking me from finding the good insights.
Just because Archimedes used infinitesimals doesn't mean he was anywhere close to inventing them, which would have required constructing the hyperreals and all of the necessary math to do that. His proofs depended on an informal notion of infinitesimals that doesn't resemble the modern definition at all.

Bottom line, with shipping a 12 pack of Cokes comes out to be around $5.50 (i.e. cost of 1/4 of a box in shipping)

In informal-logic terms this is known as genetic fallacy[1], a category which is close to ad hominem and includes almost any form of trying to address an argument by discrediting the source. The particular sub-fallacy involved here is known as attribution of motive. Brooks assumes, without evidence, that Piketty's motivation is pandering to the upper middle class, and all of his other pseudo-arguments flow from that. I guess Brooks has tired of pandering to the upper middle class himself, and is setting his sights on pleasing the elite by answering the Piketty threat. Oh wait, didn't I just try to dismiss Brooks's argument by attributing ulterior motives to him? Isn't that awful of me? Yes, it is, just as it was when he did it to Piketty. Except that he really meant it to be taken seriously, and I was just illustrating a point.

As mosquito related problems are just plain hard and in this context ther is no other viable solution, I also think the usual fear is less important in this context.

But for the sake of the argument, the fact that this mosquito comes from Africa doesn't really matter so much, as the consequences of this operation could go from making it immune to this gene, make it mutate in a different/worse direction, or have the engineered mosquitoes affect the environmenr in other unknown and not measurable ways.
The perfect int == float comparison
Scientists studied getting rid of all mosquitoes globally, and came to the conclusion it wouldn't have much of a negative impact (and a huge net positive for due ending malaria, dengue, etc.) Nothing eats exclusively mosquitoes, and those animals (birds) which do eat them could just switch to other insects, which generally are not in short supply.

I’m not sure, but perhaps eradicating the Aedes aegypti is enough to prevent most of the dengue transmission.

And the Aedes albopictus (Tiger mosquito) is also a non native specie in Brazil, so it’s probably a good idea to eradicate it too, perhaps using the same method. http://en.wikipedia.org/wiki/Aedes_albopictus
>> "The claim most paleo advocates seem to be making is that you should eat food that the body is adapted to eating."

In full, their claims fall closer to the following:

P1. You should eat healthy foods.
P2. Foods that the body is "adapted" to eating are healthy.
P3. If paleolithic humans ate something, it means our bodies are "adapted" to it.
C. We should eat what paleolithic humans ate.

The problems with the above line of reasoning are numerous. While most everyone would prefer to eat healthy when possible, the word "adapted" is ambiguous, and the argument that it's healthier to eat foods we're "adapted" to lacks evidence and is overly ambitious.

It's hard enough to examine healthiness on a food-by-food (or even an ingredient-by-ingredient) basis, so labeling broad categories of food as healthy or unhealthy is bound to be even harder.
It really depends on the situation. In a recent endeavor, I took to sites like Quora, Reddit, HN, and I went outside and talked to people on the street.

It's all about asking relevant questions that open ended and not biased. In the recent experience I had validating an idea, I ended up getting great nuggets of information that helped us tailor our app to address the pain points users found in existing products. It's also important to note here that this doesn't mean that you're guaranteed money; all you have done at this point is understand that the issues exist and that you (hopefully) have a solution. Hope this helps!
I created http://easypromocodes.com to generate business cards with promo codes for iOS apps.

The site was created with PHP, Moo.com API, the iTunes API, and the Google link shortener.

I'm not on the team, but I've used both. I would be interested in seeing both maintainer's answer to this, too.

At a high level, I can see how there might have been a bit of friction in trying to implement Wagtail on top of Mezzanine. Mezzanine's features, admin interface, and content model are fairly tightly integrated (I hope I'm not misrepresenting Mezzanine here, I think that this is an affirmative goal of the project). It provides a lot for the developer and the site admin out of the box—usable templates, basic page types, a blog, an image library. On the other hand, Wagtail core offers surprisingly little—the wagtaildemo project is a nice starting point for some basic content types, but it's just another user of the Wagtail API.

For me, the killer features of Wagtail are: deep integration with ElasticSearch, a moderation based workflow, content revision tracking, document library. It's feature list is like a love letter to institutional clients. However, that's a lot of code that is not integral to Mezzanine, and I don't think it fits with the maintainer's philosophy of "it's integrated, but not a kitchen sink." [Note: I made up this quote.]

To both maintainers, nice work, and thanks.
So i've been doing a lot of mentoring, especially recently.

A large part of it was due to my involvement in open source for over a decade, because being an ambassador for a project involves helping new people get started.

I do it partly because I love the way people's eyes light up when something finally clicks, and they see the possibilities. It don't even have to be physically there to enjoy that.

The last while it's become obvious that I need to expand how many people I am helping. So i've started writing things down in my blog, to guide people through what "Full Stack" development entails.

I'd prefer to put my money behind replacing coal plants with solar. Such as subsidies to solar suppliers for installing and running their plant, at least equivalent in scale to the subsidies offered to coal power plants through fuel rebates, special zoning to reduce land taxes, low rent for digging up the coal in the first place, and many more.
I wish the GMO developers had initially focused on products which were end-user or publicly beneficial like this, vs. just raising yields or reducing pesticide use (which are end user and societally beneficial, but can be cast by opponents as economic arguments). Without the existing anti-GMO movement, GMO would have a much easier time getting adoption in cases where it's essentially unambiguously a win (like this one).
> His proofs depended on an informal notion of infinitesimals that doesn't resemble the modern definition at all.

To the extent this is correct, the same goes for Newton's proofs, but he was able to do calculus in a practical sense with them.

However, I'm not sure what you say is correct; didn't Archimedes give a rigorous definition of infinite numbers as numbers that are greater than all natural numbers? (I.e., a number I is infinite if I > n for all natural numbers n.) And then didn't he define infinitesimals as numbers x such that x is not zero and 1 / x is infinite?
http://guildbit.com/ - Free, temporary, 10-slot Mumble servers for the gaming community

I built this for fun while playing around with the Murmur API and thought about offering premium upgrades, in addition to the free tier.

- Only about 1.5k visitors/month for the last 6 months since launch

- About 5GB in Mumble traffic/day

- Built to scale, but only costs about $15/month to keep running so far, including 2 Mumble server instances (US West/East). Thinking about adding more locations.

How do I find a good developer?
