There's only a vague resemblance between model and part. No way could you use that sprocket. Not only are the edges rough, it has voids. You could grind or machine down down rough edges, but voids make the process worthless even for making blanks.
That's about what you'd expect with MIG welding. Welding just isn't a good way to make smooth surfaces.

The low-end 3D printer people tend to obsess on the problems of building a 3-axis motion system (a completely solved problem in CNC machines) and gloss over the problems of what's happening at the weld point. The common extruder-type printers are trying to weld a hot thing to a cold thing, which never works very well. (In soldering, that creates cold solder joints. In welding, it creates bad welds.) Heating the bed plate helps a little, but once the thing being built is more than a few cm high, the build plate isn't accomplishing much. That's why most taller objects made with low-end 3D printers fail.

There's a plastic welding technique that's been in use since the 1950s that works reliably. (http://www.professionalplastics.com/WELDER). Not only is the welding rod heated, the target area is heated with hot air. This produces a solid, reliable weld.
I've suggested doing something similar for extruder-type 3D printers, using small lasers (2-5 watts) to preheat the target area just ahead of the extruder. So far nobody has done that.
I spent a few days checking out abandoned houses in Detroit this July. Most of them were built before the 70s and have plaster-on-slat walls with lead paint on top. Because of the heavy rains the wall studs and floor joists are rotten. I remember one house where the floorboards were so wet and rotten they didn't break through when I stepped on them, they sagged through like mud.

I think this is plausible, since return is based on your investment. EG: You buy a $300k property, maybe have $40k in rent, $6k in maintenance costs, but only put down $30k on the property, your total investment is $36k. On rent alone you're returning $4k (spread between mortgage+maintenance and rent income.) $4k on a $36k investment is %11. But on top of that you have added ~%50 of your mortgage payments (which are covered by rent, "free" money) to your assets.

Do you believe this is rare? I don't know the real estate market well, but it seems pretty plausible to me.

First thing I'd do is look for a city where the influx of population exceeds the new home starts. If you find something like that early on, after a few years, your return will be pretty dramatic as rental prices go up, but your mortgage is based on the price at the time you bought (which may be well below the current value of the property.)

Between appreciation and the rent paying down your mortgage balance, plus possibly a return on the rent itself, a return on equity (which really is just the downpayment plus maintenance costs) could be pretty high.
If I had to take a guess they're using something like Phonegap/Cordova (i.e., this is a hybrid mobile app -- basically just a browser view with HTML content and JavaScript that can make use of the device's hardware and accounts). A common mistake I've seen is people using the stock Android manifest that comes with Phonegap/Cordova. This manifest enables ALL permissions so all the native functionality plugins "just work" out of the box. However, you're supposed to pare down the manifest to remove permissions for things you don't actually use so you don't end up in this situation.
If that wikipedia article is accurate (80 million people at a single gathering) no battle comes close. Operation Barbarossa (i.e. the Axis invasion of the Soviet Union in WWII) involved as many as 6.7 million troops, but it took place along a 1800 mile front and over the course of nearly six months.

It makes sense that you wouldn't get nearly the same density in warfare, especially modern(ish) warfare, as you do in a peaceful gathering.
They look like you and me. They may in fact, under different circumstances, be you and me.

It's IMO dangerous to think about this sort of thing as being only possible by a certain "type" of person. The road to hell is paved with good intentions, and human beings are very, very good at rationalizing their own behavior, particularly when the descent is gradual.

"If I don't pay them [unfair wage] they'd be out of work anyways. I'm the least of the evils."

"They're earning they would be at home with this bonus, this is good for them."

etc etc. The number of rationalizations is practically infinite.

All of us are susceptible to it. I've seen people better than me fall to frog-boiling rationalizations and I'm not insane enough to think I'm immune. There's a lot to be said for reality checking yourself frequently.

Honestly, most of the time I think we would be better off without operator precedence. It just adds another thing you need to keep in your head when reading code.

Unfortunately, nearly everyone -- even non-programmers -- learned the operator precedence for arithmetic operators, which means they might be confused if those operators in a language didn't use it.
From talking to people who live in Detroit, most of these city auctions come with the stipulation that you have to get the house up to code or demolish it within 6 months, otherwise the property will be repossessed.

I hope they paid their attorneys a LOT more than that to get the fees down to $3,500. California's labor board is notoriously pro-employee and punitive towards employers who do not honor labor laws.
Everything was floating-point up until now, which plays nicely with integers...but only until 2^53 or thereabouts.
"During this assignment, they continued to be paid their regular pay in India, as well as a special bonus for their efforts on this project," said Beverly Rubin, vice president of HR Shared Services with Electronics for Imaging. "During this process we unintentionally overlooked laws that require even foreign employees to be paid based on local U.S. standards."

For someone at the senior management level (directly responsible for cross-border staffing, no less) to say that they "overlooked" such laws is either a sign that they are either utterly incompetent -- or plainly lying.
Previously, all Lua numbers were doubles. You could fit a 32-bit int into a double without trouble, and maybe the interpreter would even have an optimization for that internally, but at least conceptually, Lua never distinguished between floating point and integer values (e.g. type(1.4) and type(4) would both produce "number").

SmallTalk does have some operator precedence: unary operators bind tightest, followed by binary, keyword, and assignment.

In general, what precedence buys you is that it lets you omit grouping brackets in situations where you would almost always have to write them. Consider assignment, for instance. Without operator precedence, you will often write "x := (y + z)", but you will almost never write "(x := y) + z". By giving := lower precedence than +, you can now omit the brackets 99% of the time.

This being said, I don't think operator precedence is particularly useful for arithmetic. It's deeply ingrained in expectations, though.

Prior to this release there was the option of using Mike Pall's (LuaJIT developer) BitOp C extension module[1] for Lua 5.1/5.2 if one wanted a cleaner way of performing bitwise operations.

My favorite part is that he did it so quietly, with no marketing or build-up. Just because he wanted to.

Also, off-topic, but this is some terrible ad placement: http://imgur.com/T6MBg2x
So, with the Lua interpreter / LuaJIT divide, what's going to happen now? If LuaJIT continues to stick firmly to 5.1 compatibility it seems like they can't really avoid forking the language, which would be unfortunate.

Additive manufacturing pretty much always needs some sort of leveling phase to cope with z-axis irregularities. Without that you can't hold tolerance. Furthermore without support material you're limited in what you can build.

Looking at the pictures this seems like it makes metallic blobs approximating the shape. I suppose if you have a CNC to post-process it into something closer that may be fine. It'd be nicer to do the machining on the fly, but with the width of the material deposition it looks like it would drip down the sides if you did that.
I wanted to reply with a quick note to clarify to those quickly reading this post that it was the flash card maker, not Nintendo, adding the bricking code.

Your post is accurate, but to those not already familiar with this incident (such as myself, until I searched for stories about it), a quick read will give the impression that this was Nintendo's doing, when it wasn't.

You're mixing the concepts of realized and un-realized profit. A market price change marks your open position and gives you an unrealized (loss)gain. But to realize that you have to trade, plain and simple. And someone must take the other side of that.

A more compelling argument against zero-sum is that traders and investors have different time frames and objectives. And, indeed, the classic argument in the futures market is that a farmer who buys a hedge from a speculator represents a potential positive outcome for both.
> 250K a year is a lot to be certain but, it's hardly "1%" pay

You're right, it's only 1.5% pay. He'd have to make $350K to crack the 1%: http://en.wikipedia.org/wiki/Affluence_in_the_United_States#...

Of course, those income figures are household income levels, so if he lives with a spouse/partner/significant other who makes $100K or more, they're in.

Doesn't it matter in the way functions compose however? Definitely not my area of expertise, but similar to the classic N^2 iteration trap (for(i=0;i<strlen(str);++i) ...) you could see something like that happening by multiplying log operations together.

For example, if for each item in a this vector, I have 2 nested inner loops where I act as if the operation is O(1), I start feeling like it should perform O(N), in reality though, its performing O(N * log32^2 N). If N is 1,000,000 (not an unreasonable amount by any means), we're now talking 1.5 * 10^7 operations vs 1 * 10^6 that I expect. Perhaps arguably not too unreasonable a slowdown, but its certainly affecting the way my application scales in a way that wasn't immediately intuitive when I initially wrote the code. Again, not sure if this is an practical worry, but curious if these seemingly small differences can magnify as they bubble up through composition.
I am bummed that the "silly research" is gone. Whether intended or not, it pushed for more military research, which when not weighed against a maturation of the human race puts us in a more precarious technological imbalance.

"It's excellent at what it does IMHO [...]"

Is something that achieves a goal but has tons of externalities excellent at what it does? It's often said that democracy is pretty inefficient due to all the friction in the decision processes. Does that mean that dictators are excellent at what they do? Or are you just ignoring all the negative effects in order to make that statement?

"I can say that if Zuckerberg didn't invent Facebook in ~ 2004, it would have been invented by now, [...]"

You are implying that the only way to achieve the benefits of facebook is by operating like facebook. How do you know that a different system that provides roughly the same services, but without a central agent that sees everything and can influence everything couldn't have been invented instead?

"Do most people care? No. Why? Because they don't see any kind of real threat."

So far, I would agree.

"It doesn't interfere with their lives."

That, though, I think, is probably false. How do you know what opportunities we as a society are missing because of the dominance of facebook? I totally agree that people don't notice it, but that doesn't mean it doesn't happen. It's misleading to think of this as just "things that might happen". The effects are already happening, and not just a little bit.
Here's another way to think of it.

If the parameter space for my model includes, let's say 10 binary decisions (which is very conservative), that's 1024 possible states of my model. If I tested all 1024 states against historical data, it is likely that some of them might do very well (depending on the general architecture of the model of course). What if I then selected the successful minority and held them up as clever strategies? Their success would very likely have been arbitrary. By basically brute-forcing enough strategies, I will inevitably come across some that were historically successful. But these same historically successful strategies are unlikely to outperform another random strategy in the future. It's not impossible you'll find a nugget of wisdom hidden from everyone else, just much less likely than the more simple explanation I'm offering.

So to your point, it's not just the size of the parameter space versus the data set that matters. Brute-forcing the former alone will likely produce a deceptive minority of winners.

Anyone have insight on how "my thyroid" affects weight gain/loss? As in, does TDEE decrease when something is wrong with the thyroid? If a typical TDEE is 2200 calories, then with thyroid problems, will it go down to 1500, or is 2100 a more likely figure?
On the other hand, "innocent until proven guilty" is one of the cornerstones of modern society.

If an accusation can lose you your job, I can probably dodge my next speeding ticket by threatening to make a false accusation against them. Obviously, this isn't what we're looking for.

But at the other end of the scale, if you're put behind a desk for something that'd have you or I sat in cells awaiting trial, this isn't what we're looking for either.
Apparently there's a plan to sell lots to Detroit residents for $100 each. Most in the 1/10th of an acre size. But Detroit also seems to have very restrictive building codes that would prevent most of what's there now from being built today. At some point they're probably going to want to reconsider that if they want to make real progress.

Still, if I lived in Detroit I would likely buy a few lots because why not? For that price I might use em for art projects or something.
