This was triggered by a defamation lawsuit where a former female MP was being harrassed via facebook, made the harassement public via twitter, and subsequently sued by the owner of the facebook account. She lost the lawsuit and was ordered

So if you are a criminal that needs disposable SIM cards you just pay some cash-strapped person to get a bunch of prepaid ones for you.

That's a bleed resistor to discharge the capacitor when turning off, else it could keep dangerous charge for a long time. ESR limits current inrush into the capacitor, with ceramic caps you would need some additional current limiting.

Could be the driver is designed for a specific range of equivalent series resistance of the capacitor. High ESR could help with peak current and EMC.

A smoke detector doesn't need that much power, so efficiency of the power supply is less of a concern. You have to find a useful compromise between efficiency and use of materials. Those additional components for higher efficiency need

Asus Tinkerboard, Libre Computer LePotato. Both much more powerful than the RPi. Both available with eMMC which is much more robust than your typical sd-card.

A table saw should have a riving knife installed. AFAIK it is mandatory for CE.

I remember that even in 1997 you needed one boot-disk containing the kernel, somewhat taylored to your system (SCSI/non-SCSI, networking) already because of space constraints, and a root-disk, and the running system was pretty minimal.

Building more telescopes like LIGO, IceCube and a whole bunch of other "microphones" or "telescopes" or whatever you want to clal them. But not sure if that qualifies as "experimental" particle physics.

I was really upset about the entanglement thing. It wasn't even necessary for the plot.

Charged particles radiate away energy if you accelerate them (force them on a curved path), this energy loss is larger for larger accelerations / smaller radii. To bend the particle beam you need magnetic fields. Particles with more en

Low-level control your machine from your CAM workstation in the office building will never make much sense (where the CAM software directly talks to servos). I would prefer my (probably expensive) machine to kind of "know" what it

I know of WFL millturns with crashguard. AFAIK the crash guard is a separate component that relies on 3d models of the machine and the tools, it doesn't see anything. If you workholding is weak and a piece comes loose the crash guard p

It should not be that hard to export current axis positions and get it into FreeCAD. Look at machinekit, they have remote control and toolpath display. Pause/run/start, override of feed and spindle speeds also is easy. Detecting c

Real CNC machines have limit switches, they monitor the load on the axis and spindle servos etc etc. But that doesn't prevent running your cutter into a fixture at positioning speed and ruining the spindle bearings.

CAM can take a lot of time and need considerable computing resources. Not that much of issue today, but still, why do the same computations over and over again? Also, you will want to inspect the toolpaths before running them on real hardwa

by rmu09 8y ago
It's not that easy. You need accurate models of your machine, the tools and the stock material. Your simulation has to be linked to the real machine movements and be ahead of time so you can estop the machine before the crash happens.

There are machines that are "self-aware" in the sense that they run a simulation parallel to the NC control, slightly advanded in time, to catch catastrophic crashes and ESTOP the machine. Cutting into the machine bed can be _very

Have a look at FreeCAD Path Workbench. You won't use it to run your 200000$ 5axis mill, the 3d kernel has limitations, and the UI isn't polished and has rough spots, but it is usable.

For controlling your machine there is LinuxCNC (formerly Enhanced Machine Controller, created at NIST) http://www.linuxcnc.org and the fork MachineKit http://www.machinekit.io/ Also, latest FreeCAD has a CAM mod

btrfs send will only work on btrfs filesystems, you probably also want to backup other stuff.

backuppc works really well, the drawback is that it is kind of slow if you have lots (millions) of files.

Whatever non-ordinary matter would be, E=mc² should apply as well. That number is an upper bound, I don't believe any process is known to convert matter into a useable form of energy with reasonable efficiency and yield. Neither fusion

The tool allows one to manipulate kernel objects more or less 1:1, so documentation and help of 'ip' and 'tc' is adequate enough if you know what those kernel objects are and how they behave, but it won't help if yo

What's all the fuzz about this "sudden" change? iproute2 is part of linux (kernel) since 1999 or so.
