    [–] Are circuits (buck converters) with shared GND sound/safe? rohbotics 1 points ago in AskElectronics

    What are you powering it with? a battery? Is anything else hooked up to the power source, if so what?

    [–] ROS Newbie Warning rohbotics 3 points ago in ROS

    The discourse is significantly more active than this sub (8 posts in the last day). It is also officially sponsored by OSRF, so you have more announcements and discussion from the ROS team.

    [–] Pennsylvania will require voting machines with paper backup rohbotics 5 points ago in technology

    Sure, but it would get a shit-ton harder to enforce if everyone had proof of who they voted for.

    [–] Pennsylvania will require voting machines with paper backup rohbotics 31 points ago in technology

    Would it have who you voted for on it? Cause then it is easy to manipulate people's votes.

    For a bit of a sillier example: A company could say something like '10% off if you voted X' and get people in the general public to vote favorable to them.

    More sinisterly, someone in a somewhat abusive relationship could be more easily compelled to vote a certain way.

    [–] This car I rented mutes the radio until you put your seatbelt on. rohbotics 1 points ago in mildlyinteresting

    This thread is about a features on some cars that allows parents to lock the top speed their teen driver can reach.

    The Ford Mustang has this feature, and even the lowest end rental car mustangs have plenty of power to hit 70+.

    [–] error: cannot convert 'float' to 'std_msgs::String::_data_type Rosserial help rohbotics 3 points ago in ROS

    You need to convert the float to a std::string or char * before publishing it.

    There are many ways to do this in C++, just google 'float to string C++' to find some examples. You can then put this value in the data part of std_msgs::String and publish that.

    [–] What turns you on? rohbotics 3 points ago in ProgrammerHumor

    [–] DNA seen through the eyes of a coder rohbotics 2 points ago in programming

    Compiling and linking is the hard part.

    [–] GCC 7.3 Released rohbotics 3 points ago in programming

    Probably because the pic C compiler was absolute trash for the longest time (and probably still is).

    [–] Solder Won't Melt. HELP rohbotics 1 points ago in AskElectronics

    But it is a 8 watt soldering iron... why would you torture yourself that bad

    [–] Solder Won't Melt. HELP rohbotics 2 points ago in AskElectronics

    USB ... solder iron ...

    [–] People named Alexa. How has your life changed? rohbotics 3 points ago in AskReddit

    I have mine set to 'Kirk to Enterprise'. (My name is not kirk btw).

    [–] LKML is down (but the cat is helping fix it) rohbotics 4 points ago in linux

    Only CPUs fancy enough to have speculative execution. Low-end/cheap efficiency focused chips like older Atoms didn't have it.

    [–] Dear Sysadmins, Why Do You Use The Distro You use? rohbotics 5 points ago in sysadmin

    Most (if not all of) the stuff you mention is in CentOS.

    RHEL gets you a support contract. This can entail things like working more closely with them on patches and updates so that your mission critical systems can remain properly patched as well as stable.

    [–] North Carolina Congressional Map Ruled Unconstitutionally Gerrymandered rohbotics 5 points ago in news

    Then how do you vote in the state legislature? And congressmen? There are multiple of each in each state and the districts are supposed to be local.
