You did not take into account the energy to create those headlamps, and to replace worn batteries. I estimate each headlamp uses as much energy as a 15 watt lamp burning continuously for a year.

Depending on how much they use them (they probably last around 500 hours before being worn out) they may come out ahead or behind, but it's not a slam dunk.

To extract the heat takes 1/3 as much energy as was emitted, if that helps your calculations.

I actually believe there is a growing market for something like low frills drones. Somewhat a T34/Kalashnikov of all drones, that is short ranged, maybe with FPV, something that anyone, who can use who is able to understand a joystick and three buttons is able to command. There should be a decent market for this stuff with all kinds of crazy 3rd world militias thinking they need to drone-up, plus these things should be relatively easy to export.

I care very little about the cleanliness of my history. I mean, I care that it's not horrendous, but a bunch of extra merge commits or a few random fix-up commits don't make me think twice. However, I've found a the tools for maintaining clean history to be extremely useful for getting real work done.

My typical workflow with Git is one of incrementally appending commits to a branch, and then using git rebase --interactive to bubble sort commits by impact.

For example, let's say I am working on a feature and I stumble across an unrelated bug that's easy to fix. I fix it. Then I commit just that fix. And then I go about my day. Sometimes, my fix may depend on a small refactor or ancillary change that's not finished. So I make the change anyway, and commit it, completely broken. After finishing the ancillary dependency, I use rebase to reorder the commits so that I can test the change in absence of the bug fix, and then again with it applied.

I've had feature branches grow up to 20 or 30 commits, where 10+ of them are totally borked or otherwise need to be re-ordered. By the time I've made sense of it all, I send it out to my team as 2 or 3 pull requests with 1 to 5 commits each. In the process, I look at my code diff over, and over, and over again. I find lots of bugs by inspection this way. I enjoy writing code this way.

This way my code can be reviewed as a series of logical transformations. It's much easier to review this way. I really appreciate it when my co-workers send me clean patches to review, so I respond in kind.

In summary: It's not about a clean history (although that's a nice side effect). It's about using Git as a tool to help you and your team reason about changes.
Customers don't care about your cool technology, they pay you to solve a real problem they have. That has always been the case. If you see a successful company with cool technology, it's because it ALSO solved a real pain the customer had. There's plenty of startups doing "cool stuff" but it doesn't solve a problem, and therefore it doesn't go anywhere.

So I'd reframe the question: it's more about solving real problems. If you can solve it with cool new innovation/code, great. I assume the goal we're talking about here is to build a for-profit business.

Hackers are not the sole proprietors of provocative and disruptive thought. Is it unreasonable to consider that a non-tech visionary could be the catalyst for the next tech breakthrough? Vision, the ability to translate it into code and create a scalable product may be rare indeed. The failure rate of startups bears this out - do startups fail because an inability to implement, or an inability to see a novel idea that will truly change the world? The "no idea" application may illustrate the need for tech to become open to the possibility that brilliant code does not define innovation and that hackers may have become "too close" to the problems to see them on a larger scale outside the tech community. PG has said, "How can you see the wave, when you're the water?" Has the proliferation of tech startups resulted in hackers becoming the water? I applaud the "no idea" application and the possibility that what those gifted coders may need is a non-tech visionary that can still see the waves.

SQL Server has been one of my favorite software products of all time. As an admin it has been rock solid and not produced any headaches that weren't our own fault.

With that said, to really get the most out of SQL Server (and most likely most other SQL implementations) you really have to do your homework and put in the time to go through the features. Perhaps more than anything this is why NoSQL has taken off-- it's very simple to get going. At user groups I hear a lot of people saying they selected MongoDB because "They had millions of rows and SQL just couldn't keep up" and to me it just sounded like no one in their organization had any solid SQL experience.

It's too bad MS didn't build a 'SQL Admin' into their product that sent an email on occasion to say things like "You have a query that is called frequently and could be sped up if you simply included this column in this index. Here are some details!"

The other way to look at this is because of the fools who join an unlimited plan, but do not use more than other cheaper plans on a consistent basis, is that they effectively eliminate the pricing structure to leave just one plan which then gets capped to just beyond their average. Such a low cap obviously then defeats the point of having any unlimited plans or pricing structure in the first place.

In otherwords, this plays into the hands of the vendor to merely offer the illusion of choice - something which seems to be psychologically very important to most humans.

Yes, many people do in fact need or want an actual unlimited plan at least some of the time...

Most pull requests are the url of a repo and the name of a branch. Without a sha1, those aren't tamper-proof.

Another option is to make pull requests for signed tags, which build on GPG trust; or to GPG-sign a pull request email containing a sha1.

Neither the dailycaller.com article nor the statement on ricksantorum.com mention SOPA or ISP filtering. They also don't mention creating new laws (which a president cannot do as part of the executive branch).

Santorum's statement mentions that he'd appoint an Attorney General (also in the executive branch) that would enforce existing obscenity laws.

Its fine to disagree with Santorum on this, but its a bit misleading to say he'd force ISPs to filter content (or that he'd have the power to do so).

Please do! I've accidentally merged the wrong code on a few occasions.

While we're making feature requests:

* The order of commits on the "Commits" tab sometimes shuffle around, especially when a history contains a merge.

* Would be nice to let me annotate code (with comments) before "Send Pull Request". Sometimes I want to make some comments to guide a reviewer.

* Browser-push updates of comment threads!

* Let me comment on a file, not just a particular line, particularly empty ones.

* Discussions are often hard to follow via email because insufficient or misleading context is included.

* 100 other things I can't think of at the moment :-)

I love GitHub; it's critical to the way we work. Thanks!

Purported new feature: "Columnstore Indexes -- This a cool new feature that is completely unique to SQL Server. They are special type of read-only index designed to be use with Data Warehouse queries. Basically, data is grouped and stored in a flat, compressed column index, greatly reducing I/O and memory utilization on large queries."

Many DB engines such as Vertica, SenSage, Sybase IQ, all use column-oriented storage. Perhaps the only novel-but-obvious thing here is that these "read-only" indexes are implied to live alongside the regular DB table data, though I'm not sure how these "read-only" indexes would mesh with the need to support deletion on regular tables.

That bit of CSRF javascript does not "ignore" CSRF checking, and is not unsafe. The only difference is that it sets the CSRF token value as a request header rather than a POST value. The browser still needs to have that CSRF cookie value.

Edit: Code backing from middleware/csrf.py:

request_csrf_token = request.POST.get('csrfmiddlewaretoken', '')
if request_csrf_token == "":
# Fall back to X-CSRFToken, to make things easier for AJAX
request_csrf_token = request.META.get('HTTP_X_CSRFTOKEN', '')

Quite a while ago my ISP threatened to shut off my Internet as I had a port open for SSH. I suggested that they should be more concerned that they had admitted to either scanning my system without permission or snooping on my traffic.

That was enough to end that. Unfortunately I don't think asserting an expectation of privacy is enough anymore.

My experience has been that these features are great but not free. I often have to choose between writing expressive, elegant, DRY code that is mind-numbingly slow or writing Fortran in Scala. Much of the time our needs are better met by writing Fortran in Scala, but with a macro system it would at least be DRY Fortran.

>Since porn is on the internet, it is NOT easily accessible to minors.

How do you figure? If you've got a house with an internet connection, there's a pretty high chance the kid in the house will be able to figure out a way to access pornography unless the parents lock down the ever-increasing list of devices from which this could be accessed. I'm not saying it's something that the government should involve themselves with ... but I also don't know that diligent-parenting can ever be an effective solution to say that porn isn't easily accessible to minors.

As for pandering, with Santorum I'm not certain it's the case. Many of the things he supports politically appear to be part of his core beliefs.
I think you are confused on how displays/graphics work. An active display needs to be lit, and the more pixels you have the more lighting is required, so physical size matters less than resolution. As for the GPU, moving the pixels can require more power but you must constantly redraw as your scene changes (you could cache static backgrounds as an image, but this is often not done). GPU power needed is most definitely impacted by resolution and has absolutely no bearing on screen size.
Yep... I'm having the exact same problem.
Appassure does this. It is annoying. Their pricing isn't bad, comparatively. I didn't call them for two years.

Adding complementary features such as edges (I'm guessing this is what you mean by lines) tends to improve the accuracy. It would also be possible to do this in real time.

I don't have time to watch the full video so I don't know what features he is currently using, but in object detection nowadays most people are using some variant of the SIFT descriptor. These are built not upon edges but on the image gradient per-pixel. The current 'hot' feature in terms of frequency of use is probably Histograms of Oriented Gradients (HOG) which do exactly what they say on the tin: Take a region of the image and count how many times a particular gradient direction occurs and the total magnitudes. Slightly more difficult to run in real-time but libraries exist.
With all due respect, that is a terrible way to determine the payroll tool that will impact every current and future employee.

The single most important book in my life is one I did not finish reading.

As a teenager I spend a few weeks reading Ivan Hortan's beginning C++ in depth. But, I skipped the last few hundred pages focused on the STL. I wanted to know the ins and outs of the language, but after that I had what I wanted and I moved on. And considering it's been 15 years and I have never seen a reason to go back and read that section or even write much C++ it was probably a wise choice.

Now you could argue that different rules apply to fiction, but the choice is the same. Do I risk continuing or should I quit and try something else and it's the authors job to convince you that the rest of the journey is still worth it. Feeling you can only judge what you finish is just the sunk cost fallacy in another form, they failed and it's ok to call them on it.
This is called NACL. And as great as it is, what we really need are on-the-fly compilers/interpreters.

The web needs to be open. As much as this would appease those who want privacy/drm for their code, we all know what road this leads to. Eventually we will be forced to execute certain binaries to browse certain portions of the web. The Urchin.exe forced to execute while we divulge our lives in our browsing habits.

Google/Facebook will track us, we'll know it, and we won't be able to function without it.

We do need a vm. But more than that, we need transparency in the future choices of web standards. Their are powers-that-be that are simply salivating at how quickly developers will evangelize this technology.

All I'm trying to say is the battle seems quite planned and half-done already, and I'm not sure anyone understands the long-term consequences. I sure don't.
It's funny that you think that "deserve" has anything to do with it. Makes me think of "nice guys" who get passive aggressive when the girl they like doesn't want to go out with them, because they did nice things for her and they "deserve" it. But of course, that's not how it works.

This is the way the game is played. If you don't like it, play another game. Raging against how the rules aren't fair and people aren't getting what they "deserve" just smacks of denial.
