| * fenn is designing a different kind of beamformer | 07:22 | |
| fenn | a spatial beamformer instead of an angular beamformer | 07:22 |
| fenn | but you'll hear about that soon enough i guess | 07:23 |
| archels | What do you mean by spatial (vs. angular)? | 07:23 |
| fenn | changes the shape of the beam cross section | 07:32 |

| fenn | the angle stays the same (approximately 0) | 07:50 |
| archels | alright | 07:51 |
| archels | What do you intend to use it for? Tradeoff between bandwidth and interferer supression? | 07:51 |
| fenn | no | 07:54 |
| fenn | pics when it's working, then all will become clear | 07:54 |

| superkuh | Poor guy. He didn't do anything illegal. The Beryllium/acid splashing around is questionable, but he was on the right path, ala the nuclear boyscout. | 14:27 |
| archels | What I'm wondering is what he paid $1k for. A Geiger counter shouldn't be nearly that expensive. | 14:28 |
| superkuh | It's all on the blog. | 14:28 |
| superkuh | A good counter could easily be most of that, then the fine chemicals, and the... well, it doesn't look like he spent much on glassware. | 14:30 |
| archels | The counter he mentions goes for $619. Then there's some thorium, radium from watch dials, and americium from smoke detectors. | 14:31 |
| archels | (actually $619 for the top of the line model) | 14:31 |
| superkuh | As a person who has tried to fuse atoms in my house and been told to stop by the FBI, I can easily imagine spending that much for fissioning a few. | 14:32 |
| superkuh | Er, apartment. | 14:32 |
| archels | haha srsly. | 14:33 |
| superkuh | Yes. | 14:33 |
| archels | How did the FBI get on your tail? | 14:33 |
| superkuh | My lawyer says not talk talk about it. | 14:33 |
| QuantumG | fair enough.. pretty sure I'd tell the FBI to suck on my balls if they told me not to do anything. | 14:34 |
| superkuh | They are very scary in person when pointing guns at you. | 14:35 |
| archels | #doingitwrong | 14:35 |
| QuantumG | So were the SS. | 14:37 |
| jrayhawk | fenn: yes | e2fsck | 14:38 |
| archels | (Godwin's law) | 14:38 |
| jrayhawk | yes being in coreutils seemingly specifically for this purpose | 14:38 |
| fenn | well i wasn't sure i wanted to answer 'yes' to everything it might ask | 14:42 |
| jrayhawk | sissy | 14:42 |
| fenn | technically, i'm a wuss | 14:42 |
| jrayhawk | also ext* has a lot of dumb issues; XFS is generally a lot more idiot-proof. | 14:44 |
| kanzure | superkuh: how did you pick your lawyer? | 14:47 |
| kanzure | hey you guys might be able to help actually | 14:48 |

| kanzure | and an external enclosure that has an ide cable | 14:50 |
| kanzure | but the enclosure doesn't have a cable for power | 14:50 |
| kanzure | so i'm using power from another motherboard | 14:50 |
| kanzure | but the motherboard won't turn on and spin up the drive | 14:50 |
| kanzure | what do i do | 14:50 |
| archels | emulate a press of the power on button with a screwdriver between the appropriate jumpers? | 14:52 |

| -!- jenzebubble [jen@173-27-44-143.client.mchsi.com] has joined ##hplusroadmap | 14:53 | |
| kanzure | i should get a second and third motherboard to do a boot-over-ethernet scenario | 14:53 |
| archels | Well, is there already a power button hooked up to the motherboard? | 14:53 |
| kanzure | yeah it's not working for whatever reason, this was a "last known to be good" board | 14:54 |
| kanzure | alternatively where can i find spare connectors for ide power | 14:54 |
| kanzure | (not welded into a dumb power suppl) | 14:54 |
| kanzure | supply | 14:54 |
| archels | Just use any ATX PSU, use a paperclip to short one of the power connector pins to ground to turn it on. | 14:54 |
| kanzure | hrm okay. | 14:55 |
| archels | http://pinouts.ru/Power/atxpower_pinout.shtml | 14:55 |

| archels | No, it's supposed to be much worse. | 14:56 |
| archels | You might get to that part yet. | 14:56 |
| kanzure | yeah i'm sure the fs is corrupted or something | 14:56 |

| jrayhawk | IIRC IDE relies upon common ground for data and power. | 15:11 |
| jrayhawk | SATA does not. | 15:11 |
| jrayhawk | So you may fry the drive if you don't ground out your two power supplies. | 15:11 |
| kanzure | dafdafadfadfa | 15:11 |
| archels | jrayhawk: It's grounded via the HDD. | 15:12 |
| archels | Half of the IDE pins are ground, which are connected to GND of the power connector. | 15:12 |
| archels | Just don't try to hotplug. ;) | 15:12 |
| jrayhawk | "15:15:34 omg/jblake: a lot of them just connect those lines on the controller board to the common ground plane, so you'll get a ground loop that can carry a fair amount of current" | 15:16 |
| jrayhawk | "15:15:57 omg/jblake: switching-mode power supplies tend to have rather floaty grounds :-(" | 15:16 |
| archels | For a ground loop, you'd need more than one ground connection. | 15:16 |
| kanzure | why isn't jules or steve in here | 15:17 |
| kanzure | playing omgwallhack bridge is not my idea of a good time | 15:17 |
| jrayhawk | Steve actually fried a drive doing that back in highschool | 15:17 |
| archels | I have an EE degree, you can take my word for it. :P | 15:17 |
| kanzure | and i have a degree in rumpology | 15:17 |
| kanzure | a phd, specifically | 15:17 |
| kanzure | forthcoming | 15:17 |
| jrayhawk | lucky! | 15:17 |
| kanzure | :( | 15:17 |
| archels | Your PC PSU powers the drive and nothing else, right? So where is the loop? | 15:18 |
| archels | A dangerous ground loop arises when the PSU powers the HDD *and* the motherboard, and the PSU<->HDD ground connection is insufficient. | 15:20 |
| archels | Then the signal ground wires will start carrying significant current. | 15:20 |
| archels | anyway, night | 15:22 |

| QuantumG | today's Russian spacewalk in 3 minutes http://www.youtube.com/watch?v=_LQD1NlwUwI | 18:36 |
| jrayhawk | kanzure: not sure about your question; I have a Matrox G450 MMS Quad that hasn't worked for years because Matrox open source support is a joke; Jaton makes a variety of quad-output X11-capable cards for ~$150 | 19:01 |
| jrayhawk | s/X11-capable/xorg-compatible | 19:02 |
| jrayhawk | Getting one quad-output card working with Xorg's software infrastructure will be a *lot* smoother than any multi-device setups, by the way. | 19:02 |
| kanzure | quad-output is the best you can do? | 19:03 |
| jrayhawk | Matrox makes ridiculous cards that do more, but they'd be expensive (medical industry) and have shit for support. | 19:04 |
| jrayhawk | IIRC they have a 16 output card. | 19:04 |
| kanzure | that's better | 19:04 |
| -!- Fiohnel [~r3idslash@111.94.200.11] has quit [] | 19:06 | |
| jrayhawk | anyway, just to warn you, with xorg, you get to pick any two of Xrandr, Xinerama, and multi-device support. | 19:06 |
| jrayhawk | DisplayLink support (which'd be a fairly cheap approach to a large number of displays) is pretty bad. | 19:07 |
| jrayhawk | Just in case you were tempted to try that. | 19:08 |
| kanzure | ah it was displaylink that i was trying to remember | 19:12 |
| jrayhawk | xorg can't dynamically allocate them, only supports one at a time, requires that it be the primary device in multi-device setups, and refuses to operate it in anything but the highest EDID-returned resolution even if that resolution is too big for the displaylink framebuffer. | 19:15 |
| jrayhawk | I assume that, like many things in xorg-land, nobody wants to fix it because everything's moving over to Wayland anyway. | 19:19 |
| kanzure | wayland? | 19:39 |

| jrayhawk | Wayland is the new compositing window manager that ditches all the X11 cruft, since obviously applications don't care about drawing primitives or buffer sharing or even network abstraction on modern GLES platforms. | 19:55 |
| jrayhawk | http://blip.tv/file/get/Linuxconfau-XAndTheFutureOfLinuxGraphics549.ogv is a compelling summary | 19:56 |
