  1. Re: So who's going to buy them? on Radioshack Declares Bankruptcy · · Score: 0

    Digikey and Mouser make their money from selling to engineers, not hobbyists.

  2. Paper tape on Systemd Getting UEFI Boot Loader · · Score: 2

    Maybe it's time to switch back to paper tape boot loader, or better yet, toggling it in. That would be more secure, and most importantly, more reliable. I've had it with all the security bullshit being added. Just more frustration for the end user.

  3. Re: XPS 13 works great on Dell Continues Shipping Fresh Linux Laptops · · Score: 1

    No, the 2014 model was 1920x1080, just could choose between i5 and i7. I don't see how higher resolution on this new model will help with a 13" screen.

  4. XPS 13 works great on Dell Continues Shipping Fresh Linux Laptops · · Score: 5, Informative

    I have a 2014 model of the XPS 13 and it runs Fedora seamlessly, including hibernation, camera, and touch screen. Yet it was still cheaper to buy an windows 8 version of the XPS 13 from microcenter and wipe it, rather than the preloaded developer edition from Dell.

  5. Re: A sense of scale on Spire Plans To Use Tiny Satellites For More Accurate Weather Forecasts · · Score: 1

    Seems what they are trying to do is measure the propogation as tangent to the earth as possible; i.e. get a really long propogation through the atmosphere. That would allow them measurements nearer the surface. Now if you did that from several directions, it may be sort of a CT scan, and you can isolate regions instead of the whoe path.

  6. Re: A sense of scale on Spire Plans To Use Tiny Satellites For More Accurate Weather Forecasts · · Score: 2

    They are not. The combination of L1 and L2 allows for estimation of the ionospheric delay since the delay is proportional to frequency (difference between L1 and L2). It's all moot now anyway with the availability of reference stations to obtain a correction.

  7. Re:TWT based on TWEETHER Project Promises 10Gbps MmW 92-95GHz Based Wireless Broadband · · Score: 1

    Is it possible to get tens of watts at W-band without spatial power combing or other hairy stuff? I'm doing some GaN load pull right now, but it's no where near W-band.

  8. Re:Disrupt to ISP's Gorilla Broadband?? on TWEETHER Project Promises 10Gbps MmW 92-95GHz Based Wireless Broadband · · Score: 2

    Could something like this could completely hose all the ISP's if open sourced and if it works well? Here's the concept: People like the dd wrt folks could customize router firmware to act as repeaters and whoever wants can set up relay stations with home type routers, weatherproofed and sitting on a pole outside if need be, creating a de facto municipal wireless broadband network without needing ISP's. I guess some question are: how to hook it up to the regular Internet's backbone, address space, etc. Could a Gorilla Internet be created with something like this?

    Not really, as the beamwidth on these antennas is 1 degree. You would need multiple antennas aimed at multiple neighbors. This seems strictly point-to-point back-haul.

  9. TWT based on TWEETHER Project Promises 10Gbps MmW 92-95GHz Based Wireless Broadband · · Score: 1

    The TW in TWEETHER is for a Travelling Wave Tube, which is about the only way to get decent power at mmWave, thus these nodes are not going to be cheap. Why not just use the Ka band backhaul, where you can get soild state PAs, and push it to 4096 QAM, or perhaps the new angular momentum diversity. Is all the bandwidth really eaten up at Ka band, even given the narrow beamwidths?

  13. Re: Nosedive on Tumblr Co-Founder: Apple's Software Is In a Nosedive · · Score: 1

    My Apple TV 3rd gen disconnects permanently from iTunes as soon as it goes to sleep, and requires a reboot to reconnect. It's been doing this for 2 years, irrespective of software updates on all devices. I'm using Ethernet, and I assume Apple only gives a shit about WiFi, and refuses to fix it. Bought a Amazin Fire and put on XMBC, can stream MKV directly off the NAS. Much nicer. Fuck Apple.

  14. The 60's on Multi-National Crew Reaches Space Station · · Score: 1

    No, I think 100 years from now the 60's would be the birth of the space program, and that mankind has been fucking-off for the last 40 years. Sorry, I watched 2001 the other night. That's what it could have been like.

  15. Amino acid data? on Philae's Batteries Have Drained; Comet Lander Sleeps · · Score: 1

    So did they collect the data that tests for chiral amino acids? I assume that would be the mass spec?

  16. I should also point out, I could not get an answer out of the Google Fiber lady, at an IEEE meeting, what they mean by "no servers". She danced around the question. I asked her if I can continue to run my torrent server; no answer? I do know they won't assign static IPs, which is what I have now.

  17. Google Fiber seems to be rolling along in KCMO, and is expanding out into the metro area. Short of building their own networks, the cities should cut the red tape to make fiber installation as easy as possible. The $ cost should be technical, not wasting it on legal fees. Although they need to safeguard against evil companies (i.e. Comcast and Time-Warner). Still yet unknown if Google Fiber turns evil. They will be in my area (Overland Park, KS) soon.

    Doesn't a person break, on average, about 3 laws a day, mostly federal? Time to fill them back up! I'm sure the prison-industrial complex can lobby for that.

    Hell, Maxwell's treatise on EM was released around the time of the U.S. Civil war. High school physics really only covers basic Newtonian stuff, and maybe some 18th century EM.

    you can't even carry a freaking sword

    Do you somehow find yourself aggrieved by not being able to carry a sword with you? Is it ruining your cyberpunk look or something?

    Or are you just looking for things to kvetch about?

    I should think there's very little call for walking around with a sword.

    I fence epee, so yes, I do want to carry a sword, probably in cane form. Fortunately in Kansas it is perfectly legal for me to do so.
