Ask Slashdot: How To Begin Simple Robotics As a Hobby?

theguru Mini Sumo (166 comments)

Rules: http://www.botlanta.org/mini-sumo

You can get kits for $100 or less, focus on the programming issues of controlling mechatronics, and reading sensors. Contests happen all over the place, and the robot is a decent starter platform for other contests, like line following.

Jobs Bill Funds Safety Network With Spectrum Sale

theguru Re:Unacceptable (147 comments)

You've got pine trees with nearly 15 inch needles there? Holy cow!
Maybe they're closer to 1/4 wavelength, but I'm betting the density of moist organic matter has more to do with it than the length of the needles.

Teenager Tries To Hire Hitman Via Facebook

theguru Re:What a shitbag... (464 comments)

God made man. Sam Colt made them equal. What martial arts do you know of where people do not compete in weight classes and gender categories?

Unfortunately the 20 year adult old victim in this case would be legal prohibited from exercising her right to self defense with a firearm in most states.

Judge Declares Federal Healthcare Plan (Partly) Unconstitutional

theguru Re:Before you pat yourself on the back... (1505 comments)

So in other words, if this part goes, and the rest stays, what are we left with? A bunch of smaller corporate hand-outs that don't fix much of anything in a horrendously broken system. Most people will still have the shitty insurance they already have, and they will see their costs continue to rise the same way that they would have if nothing at all had happened..

Actually no, the administration has already said this part of the law would sever a large part of the rest. Preexisting condition coverage for instance. If people aren't required to have insurance, companies can't be expected to cover those with preexisting conditions, because then no one would need to actually buy insurance until it was needed.

Cheap 3D Fab Could Start an Innovation Renaissance

theguru Re:Unit can also do 3d printing (258 comments)

No reason. I have a RepRap style extruder head for my 3'x4' CNC router, a head that holds a Sharpie marker on the same co-axis as my router, a dremel for small work, and a 2.5HP Porter Cable router motor for bigger work.

I haven't done it yet, but have some parts that I will probably extrude, then switch to the dremel to drill some holes out to the proper size, and maybe to mill a few surfaces smooth (printed parts have a stringy/webbed texture).

Drunken Employee Shoots Server

theguru Re:"Automatic" doesn't mean what you think it mean (309 comments)

The feature you are referring to is "slide-lock". Most modern semi-automatic pistols have it with the exception of some smaller "pocket" pistols. Some guns will release the slide and put a new round into battery automatically when the next magazine is inserted, and some require the slide release to be flipped to release it.

ACLU Sues To Protect Your Right To Swear

theguru Re:Same goes for flipping off cops (698 comments)

42 U.S.C. 1983, commonly referred to as "section 1983" provides:

Every person who under color of any statute, ordinance, regulation, custom, or usage, of any State or Territory or the District of Columbia, subjects, or causes to be subjected, any citizen of the United States or other person within the jurisdiction thereof to the deprivation of any rights, privileges, or immunities secured by the Constitution and laws, shall be liable to the party injured in an action at law, Suit in equity, or other proper proceeding for redress, except that in any action brought against a judicial officer for an act or omission taken in such officer's judicial capacity, injunctive relief shall not be granted unless a declaratory decree was violated or declaratory relief was unavailable. For the purposes of this section, any Act of Congress applicable exclusively to the District of Columbia shall be considered to be a statute of the District of Columbia.

The Art of Unit Testing

theguru Re:Pet peeve - the purpose of testing (98 comments)

This may be the purpose of manual testing, but the idea of having high code coverage with automated testing it to prevent regressions, minimize time to release, and even act as documentation via example usage.

It's less about release N, and more about release N+1.

Gun With Wireless Arming Signal Goes On Sale Soon

theguru Re:Wait hold on mugger... (457 comments)

Yeah, when someone takes my gun away to use it against me, they'll have to use it as a blunt force weapon, because it'll be empty.

Police Arrest Man For Refusing To Tweet

theguru Re:How would that work (550 comments)

You're obligated to comply with a lawful order from a police officer. Failing to do so is unlawful. So if the cop says,"tell them to leave [because you've created a dangerous situation by being here]" you'd better comply, or you'll get sent down. Just because they told him to do it with twitter makes no difference.

Wow, what country do you live in? Mine has a constitution with due process protection, freedom of speech, and other useful constraints on government to prevent them from just ordering me to do things like that.

Acorns Disappear Across the Country

theguru Just the opposite here (East TN and North GA) (474 comments)

My father and I were just commenting over the Thanksgiving holiday that there are more acorns around his house and mine than in recent years.. a LOT more. Our squirrel population is exploding. We've been raking them up and throwing them in sealed garbage cans.

Maybe they should come to my house and collect them for the sparse areas? :)

US Supreme Court Allows Sonar Use

theguru Re:Third world (374 comments)

Of course they aren't, that isn't the point. The point is, they have a significant naval presence in the Pacific, and are more than enough reason to conduct sonar training exercises there.

True space age tech in our daily lives

theguru theguru writes  |  more than 6 years ago

theguru (70699) writes "Being an election year where several candidates have discussed cutting NASA's budget, I'm often asked what the space age has done for us. NASA has created a fun little site (warning: Flash), showing common items around the house with origins and connections to NASA research."
