I've never been to a conference with a junk submission accepted, or a junk presentation. Many conferences in my field reject submissions that are real but low-quality, even for a poster session. Talks are always competitive. I chaired a conference last year. We rejected some submissions that were uninteresting or poorly written. For most of those, the submission was read by two professors before rejecting it. We received no computer-generated submissions.

I sometimes get spammed or "invited" by suspiciously looking conferences. I never go to these. Why would anyone attend a conference that is lower-quality? There always are good conferences around. You have a choice.

Re: your sig: we had dozens of districts in Philadelphia vote 100% for Obama in the last election. Dozens. You'd think at least one would accidentally vote for Romney. This happened in 2008 as well, in slightly fewer districts. It's over in the USA.

Could you provide a link to district voting reports?

That one in Caucasus region of Russia was totally rigged, as many other districts in that region as well. Polls showed less than 15% turnout at the polling stations, reports show 100% turnout. This is a demonstration of loyalty to the central government by the local government, and of course blatant election rigging. The rissing is obvious in statistical analysis of the polling station data.

Mechanical tools: screwdrivers, wrench kit, pliers, cutters (plier style), cutters (x-acto), hammer, metal file (to round an odd sharp corner), tape measure, heavy-duty duct tape, lots of plastic cable ties. I also needed a drill to install an odd rack shelf, so throw one with some drilling bits if your budget allows. I don't know what cables you use, but tools to fix cabling may come in handy (multimeter, soldering iron and solder, shrinkable tubes, special tool to terminate cables, etc.). If you have fiber optics, get a good push-action connector cleaner.

I second that. Install Microsoft Security Essentials, it's free. Do not turn off automatic OS updates (they are on by default, so you just install the OS). Use Firefox. Done. Setting up Windows is really no-brainer. Just a single more thing: I turn off automatic reboot after updates (several ways to do it; I use gpedit). There is nothing more anoying as being forcibly rebooted in the middle of a game :). When this setting is turned off, there will be a periodic reminder to reboot when needed.

If you do nothing more than above and install a few licensed programs (Steam, games, software from well-known vendors), the box will likely stay secure indefinitely. Now if your kid keeps installing various random stuff and shitty software himself or does other risky things in the internet, it MAY get infected (even with MSE). I don't think you should stop the kid from doing it... this is just a part of healthy exposure to the real world and learning experience how things work, whom to trust and whom don't.

Comment: SMD kits and vice (Score 1) 208

I found these cheap and large SMD resistor and capacitor kits to be practical. Just ask the vendor to pack all kits regardless of component size into SK128A or SK128B boxes... the cheaper box they use by default for larger component sizes is of too low quality. They will do this free of charge if you ask.

For vice, I use Bernstein with various attachments.

The rest will depend on what you do.

I have new models of Weller soldering irons, and am less than impressed with their design and quality, especially for the top price they charge. Things came from Weller with manufacturig defects, broke mechanically very quickly, etc. User interface is not intuitive, and touch screen is awkward comparing to a knob and buttons. I'm getting Hakko now instead (= made in Japan), will see how it works out.

Atmospheric conditions matter because you still have to send one photon of the entangled pair over the link. When air is still and clear between the islands, roughly one-in-thousand photons make it from La Palma to the receiver telscope in Tenerife. Available technology limits how much of this loss can be tolerated, and there are inefficiencies in other parts of the experiment as well. The whole experiment is indeed at the edge of what is possible with today's technology (which is one of the reasons it's published in Nature). But, you know, technology improves with time.

We transmit a quantum state, which is impossible to transmit via classical communication.

The auxiliary classical communication (about two bits per quantum state) has to be there, because faster-than-light communication is impossible. These classical bits carry no information about the quantum state being teleported. If one could teleport a quantum state without this auxiliary classical communication, faster-than-light communication could be implemented as well... which impossible in nature as far as we know.

I heard from Rupert Ursin that this is the longest free-space range on Earth that has significant infrastructure at both sides. This is to say, scientists can keep small optics labs in telescope buildings, and live in hotels. Also we had a 1 meter diameter telescope at the receiver station in Tenerife (normally used for optical communication with satellites), which is no small beast and it occupies its own dome. One could of course find many longer ranges between mountains, but logistics would become more expensive and difficult... we'd have to build and drive (or airlift) a container full of gear, and probably live in a tent for months.

Here is a picture of La Palma station sending a tracking beam to Tenerife, above clouds:

By the way one doesn't get to clill out on beach very much. It's a long drive to the mountaintops where the observatories are situated. When I was there last April, we had snow in the mountains on both islands. I had, like, one day on beach and two weeks of night shifts in the labs. This still was a lot of fun :).

Did you check what spam filtering options are available at pair? The default could well be let your client filter, in your case Google, but you can change that to discard and play with the thresholds. Also make sure you switch on greylisting. However I agree that pair spam filter is not the best. It took me a while to set up, and the result in terms of false negatives and positives was still not perfect (though very close to that).

Second that. Have been a happy customer for 10+ years. is not cheapest, but the uptime, stability and service (averaged over 10 years) are very good. Just email them and ask what they can do for you. I guess, your biggest cost with Pair will be bandwidth, but they have redundant connections and an extremely good uptime (I estimate 99.97%+). They are a trustworthy and very stable company.
