I think this is a big factor in crime.

For most here, $182,000 is definitely not worth the risks. They have good secure jobs where they could save that over a few years, where taking the money would not cost just their job but their entire career. Right or wrong doesn't even factor in, taking that money and running it a bad business decision.

But there are others, dirt poor, who live off of less than $20,000 a year. Some live off even far less than that. They have no career. To them this is 10 years of payment with vastly little risk. It is nowhere near the as bad a business decision to take the money and run. In the more extreme cases, there is so much to gain with little to lose.

And this is completely ignoring those who don't make this much in their lifetime.

I'm not sure why they're so obstinate about using a very-high-frequency band of RF for this. Is GPS not accurate enough? How about a more mechanical method, or near-field communications?

the only way to get them to work is to dig a trench along the perimeter of a lawn and install a wire that creates the electronic fence needed to ensure the automaton don’t wander beyond the property line.

If they really want to implement that method, shopping cart locking systems have done it before, and they don't need 6GHz+ RF:

I'm all for robotics, but the thought of an unattended machine whirling around my yard with spinning blades (of death) worries me. Granted, my "lawn guy" races around my yard already like a NASCAR driver on crack, but part of me wonders what sort of mishaps this robotic vacuum might get itself into. Small animals, toys, sprinkler heads etc.

It's one thing if your vacuum sucks up a kid's toy, or harasses your cat. Imagine the potential liability if your robotic lawn mower left your yard and entered your neighbors.
Is this the same technology used by invisible fences intended to contain dogs in a yard?

This is a valiant effort but I wonder how the practical allocation of the jobs is determined. If the market salary for an employee is 50k, if you raise it to 70k, you will probably have a lot more applicants than positions. Do the current employees get grand-fathered into the job despite more qualified candidates? When hiring new employees, how do you decide among the increasing rank of equally qualified candidates?

That being said, a bump in pay will almost certainly help reduce costs associated with retention and retraining and may turn out to be a good business decision, not to mention the publicity.
This process does not replace tax return, so I am not sure why would you compare it to filing a tax return. It's a required step to establish your paycheck withholdings. You will do it anyway. There is always a risk of penalty if you make a mistake while filling out this form or have unexpected income during the year.

No, its not. Shoving more components into a single IC is what Moore's Law is about. Performance per core was one manifestation of that, but a "core" isn't the fundamental unit the Law addresses.

The thing is, it's simply a lie. The idea that the law doesn't cover these "innovative" and "disruptive" business models is an illusion.

Uber, AirBnB, Kickstarter etcetera, they're not doing anything fundamentally new, they've just added a new coat of paint to a very old business model. A business model that is in most cases already clearly regulated (especially outside the US), and, especially in the case of Uber, these companies are deliberately flouting these laws and regulations.

There is however a major difference in how these companies handle the problem. AirBnB constructively works with regulators to adapt both rules and its business practices. Uber treats the law with less respect than the Russian mob and thinks it can bully governments into surrendering consumer and labor protections. Kickstarter is mostly known for sticking its head in the sand an hoping things will blow over.

But in all cases, the law tends to cover exploiting, profiting from, soliciting and provoking illegal activity as well as the scams themselves. These companies do not operate in a legal vacuum, other than the Silicon Vally echo chamber.
Am I the only one who thinks that iRobot is actually doing a very poor job with the Roomba cleaning algorithm?

Why can't we have a robot that maps the surface and then cleans accordingly? I always get irritated when I look at my Roomba doing it's job.
Because I don't have a double-yellow line painted between my property and my neighbors? Machine learning is fine and all, but you need something for the machine to learn from. Without some kind of outside influence, my grass looks the same as the grass across the invisible property line.

Not only that, but you need a system to account for wheel slippage, etc. No matter how accurate your compass, how awesome your internal map, you're eventually going to go off course. Best case, your bot mows your neighbor's property. Worst case, it wanders into the busy street, or into your pond. Systems like these beacons or underground wire help ensure this doesn't happen.

Are you sure you've read my post correctly?

In fact, i stated the exact opposite: there is nothing inherently bad about Windows. I run Windows myself as the host OS, using ConEmu to wrap PowerShell.

I am not dogmatic. I use vim when it makes sense, Sublime for what makes sense, and a full-blown IDE, you guessed it, for when the strengths of an IDE are useful. Yes, i am using these across operating systems just fine.

I am versatile. I can use OSX, Linux and Windows to develop code, as i've abstracted away the development environment, and decoupled it from the machine and OS i am typing the code on.

And that is the decent dev mindest.

I am not trying to force anything down your throat, and it surprises me that you would think that.

That's the one thing that's not really a problem, at least not properly dealt with. Take the website that has awesomely not disclosed whether a user account already exists with that email address or not.

Now go to that websites 'Register'-page. Enter the same email address and continue. I bet you half a dogecoin you will get an error message if an account already exists with that email address.

Of course, this is sort of solveable by following the same tactic. Just saying "An email has been sent to bla@bla.bla with furhter instructions", which in case of an already existing account could say "Someone tried to register with this email address, but an account already existed."

Something to be aware of.
Thank you for clarifying that haha. I forgot that on HN one has to articulate all ideas as formally and rigorously as possible in order to prevent the pathological cases from becoming the centerpiece of a conversation.
Yeah, I mentioned aRTs but I was actually thinking of Jack (too late to change it). The annoying thing with these different sound systems is that it turns a general purpose workstation into an either/or proposition.

- The applications that depend on pulseaudio were really not happy when jack was the sink.

- Skype wouldn't work.

- Because of the real-time requirements of the sound applications, everything else felt absolutely sluggish.

- The volume control stopped working.

All in all, I'd have to setup a separate system just to run jack-dependent applications.
Rust vs. Ruby: building an API
Windows overcame its audio latency issues in the Vista days by introducing WASAPI (Windows Audio Session API), an API especially designed for professional audio processing.

It grands an application exclusive, direct control of the audio hardware drivers, bypassing the higher-level audio layer of the OS.

That + real-time threads (I do not know how old that feature is) allows for pro-grade latencies.

Fun project, I've always wanted to write web stuff in python.

However I think it is a mistake to go 95% of the way towards imitation. Either you go 100% as to provide compatibility, or you distinguish yourself enough to not cause confusion.

I'd much rather have compatibility with real python code, than constructs such as 'do..while' and '[4 til 9]'.

I must admit inline 'def():'s are nice though.

Here's a little more info about the company, the goblins comic guy contracted with. They also did another kickstarter for a card game for Kingdom of Loathing online game at around the same time. https://www.reddit.com/r/kol/comments/2b9xs5/update_for_inte... which was late and underdelivered and apparently the company tanked.

Also, apparently the comic creator doesn't even have the list of kickstarter backers, only the game company did. He can't even directly email people. I'm not sure how he's verifying who kickstarted the game.
I'd heard over the years that working with isochronous systems was difficult. I'd done a number of real-time systems before, and written OS schedulers and NTP-like systems and so forth. A little audio work should be a walk in the park, right? A little manly-man programming from the wrist and we move on to real problems. So I walked into an audio project thinking that "Oh, this latency and synchronization stuff, how bad could it really be?"

Bad.

Nailing down buffer-bloat and sources of latency and jitter in an isochronous system took several months, the last few weeks of which were 80-100 hour weeks just before ship. Several times we thought we'd fixed the issues, only to find that our tests had been inadequate, or that some new component broke what we had built.

I remember nearly being in tears when I finally realized what the clock root of the audio system actually was, and that it wasn't what people had been using. From there everything fell into place.

Don't pull the number of buffers you have out of thin air ("Oh, six is enough, maybe twelve, don't want to run out in my layer of the system, after all...") Don't assume your local underflow or overflow recovery strategy actually works in the whole system. Don't assume your underlying "real time" hypervisor won't screw you by halting the whole god damned system for 20ms while it mucks around with TLBs and physical pages and then resumes you saying, "Have fun putting all the pieces of your pipeline back together, toodle-oo!" Put debug taps and light-weight logging everywhere and attach them to tests. And know what your clock root is, or you will be sunk without a trace.

At the time it was seen as an outrage (in my view correctly so) and promptly banned. Wikipedia has a clear conflict-of-interest policy [1] for good reason.

I'm not saying a shell isn't useful. I don't use an IDE for any of my git workflow (I actually find git to be poor on Windows, which is a good reason to choose Linux); but for navigating the code.

Shell utilities that deal with plain text often get the nuance wrong, because they don't have the full syntax tree to deal with. Mostly you're using regular expressions; which often get you close but not quite right. For navigation, people often would use cscope/ctags something else anyway; and text searching often isn't as good as a semantically aware find.

I don't use an IDE beyond vim for my C++ work; but am considering clion. So far I'm not entirely convinced, it doesn't handle some of the more complex C++ constructs correctly.
