Video Are Matt's Robot Hexapods Creepy or Cute? (Video) 35

University of Arizona grad student Matt Bunting doesn't come across as a mad scientist. That's a very good thing, because his robot hexapod creations are easy to imagine crawling across the USA in large hordes, devouring everything in their path and using all the electricity they come across to feed their Queen Hexapod, a 3-D printer mounted on a hexapod chassis that turns everything fed to it into more robots. Luckily, the real life Matt is an affable (self-described) "Roboticist, Electrical Engineer, Musician, and Rock Crawler" who freely admits that at this time his robotic creations have no practical application whatsoever. This is probably true, except for the fact that they can liven up a music video like mad, as you can see on YouTube in Pedals Music Video (featuring REAL robots) . Our little video is a lot simpler, of course. In it, we interview Matt and he tells us what he's up to with his robots, and gives some 'how to get started with robotics' advice for budding young engineers. (Alternate Video Link)

I am saying that its design sacrifices robustness in favor of performance and features at every turn. It might be more crashy, but the bigger problem is it ensures you have no usable logs when it crashes. And it doesnt have to be a crash for it to be troublesome, for a single example in the quest for shorter boot times it starts services without making sure that dependencies are actually working - that normally wont cause the entire system to crash but so what?

Still not what I want on my system. I dont really care how long it takes to boot, I just want to make sure that when it's finished it's really finished. Systemd in so many ways copies windows concepts instead - like how they make it supposedly boot faster - by rushing along to draw a GUI before things are actually ready to use.

Not saying systemd is as bad as windows - and the massive improvements in boot speed are not all illusory! but they do come at the cost of reliability and correctness, and that's simply not a good tradeoff for people using the OS in a traditional manner.

We are in a War on Faith, because Faith justifies anything and ISIS takes it to extremes. But in the end they are just a bigger version of Christian-dominated school boards that mess with the teaching of Evolution, or Mormon sponsors of anti-gay-marriage measures, or my Hebrew school teacher, an adult who slapped me as a 12-year-old for some unremembered offense against his faith.

Hm. The covenant of Noah is about two paragraphs before this part (King James Version) which is used for various justifications of slavery and discrimination against all sorts of people because they are said to bear the Curse of Ham. If folks wanted to use the Bible to justify anything ISIS says is justified by God's words in the Koran, they could easily do so.

18 And the sons of Noah, that went forth of the ark, were Shem, and Ham, and Japheth: and Ham is the father of Canaan.
19 These are the three sons of Noah: and of them was the whole earth overspread.
20 And Noah began to be an husbandman, and he planted a vineyard:
21 And he drank of the wine, and was drunken; and he was uncovered within his tent.
22 And Ham, the father of Canaan, saw the nakedness of his father, and told his two brethren without.
23 And Shem and Japheth took a garment, and laid it upon both their shoulders, and went backward, and covered the nakedness of their father; and their faces were backward, and they saw not their father's nakedness.
24 And Noah awoke from his wine, and knew what his younger son had done unto him.
25 And he said, Cursed be Canaan; a servant of servants shall he be unto his brethren.
26 And he said, Blessed be the Lord God of Shem; and Canaan shall be his servant.
27 God shall enlarge Japheth, and he shall dwell in the tents of Shem; and Canaan shall be his servant.

I don't think people understand the Unix philosophy. They think it's about limiting yourself to pipelines, but it's not. It's about writing simple robust programs that interact through a common, relatively high level interface, such as a pipeline. But that interface doesn't have to be a pipeline. It could be HTTP Requests and Responses.

The idea of increasing concurrency in a web application through small, asynchronous event handlers has a distinctly Unix flavor. After all the event handlers tend to run top to bottom and typically produce an output stream from an input stream (although it may simply modify one or the other or do something orthogonal to either like logging). The use of a standardized, high level interface allows you to keep the modules weakly coupled, and that's the real point of the Unix philosophy.

"You don't have to. If you really want your old way then just have journald pass everything along to syslog and it's back to normal."

Unfortunately that's not quite true. You *can* configure systemd to spit out text logs as well as the binaries but that is a delayed process, so in the one case where you MOST want text logs (where a crash has occured with the file open) it's absolutely worthless.

I think there is a major difference between having a big possibly over-complicated application program in userspace, and putting something like that in a critical spot in the system itself.

If your application program has a flaw, it's probably not a huge deal. Maybe it crashes occasionally. You save often, you have autosave, it's not a big deal.

But a system component that can crash the system, render it unbootable, hand control to a hostile third party, etc - it's much more important in that case to keep things clean and proper to keep the machine itself stable.

Part of the disconnect between the Sysd cabal and the traditionalists here is about what we mean by the machine. We are often running linux on bare metal as our workstation. From what I have been told, they typically run it in virtual machines on server farms instead, and use Apple workstations. So from their point of view, it is just another application, and it shouldnt be a big deal to restart it occasionally - especially after they put so much work into improving boot times. But from our point of view, we dont care much about fast boot times, we want a stable system that doesnt need to be rebooted all the time.

Charlie Stross recently posted a very good take on this: This is a permanent change. Whatever happens during the first few years is basically irrelevant, compared to the long-term results. Did Norway separating from Sweden cause short-term economic upheaval? Does that matter at all a century later?

This is a long-term change, not a short.term one. Any voter should consider the probable situation twenty or fourty years from now, not whatever happens in a year or two.

Shops like that end up with a reputation. They work by burning through suckers who haven't heard about them yet. Turnover rate's usually fast and pretty close to 100%, The recruiters for one of the local grind-houses are getting desperate and don't tell you who they're recruiting for until you get to the end of their pitch about the "great opportunity" they have. In the past year I've heard two separate co-workers listen through the whole thing, get to that part and say "Oh, them? No thanks, I'm not interested."

Funnily enough, contractors are usually get a better work/life balance at the grind-houses I've seen lately. The companies will abuse their salaried work base for as many free hours as they can get, but contractors put in their 40 a week and are done. You can tell when they're actually desperate to get something out the door because that's when they ask the contractors to work paid overtime.

It depends on your design goals.

In Asimov's story universe, the Three Laws are so deeply embedded in robotics technology they can't be circumvented by subsequent designers -- not without throwing out all subsequent robotics technology developments and starting over again from scratch. That's one heck of a tall order. Complaining about a corner case in which the system doesn't work as you'd like after they achieved that seems like nitpicking.

We do know that *more* sophisticated robots can designed make more subtle ethical systems -- which is another sign of a robust fundamental design. The simplistic ethics is what subsequent designers get when they get "for free" when they use an off-the-shelf positronic brain to control a welding robot or bread-slicing machine.

Think of the basic positronic brain design as a design framework. One of the hallmarks of a robust framework is that easy things are easy and hard things are possible. By simply using the positronic framework the designers of the bread slicing machine don't have to figure out all the ways the machine might slice a person's fingers off. The framework takes care of that for them.
