I think he means the edges overlapping the right amount, not complete overlap, and yes, because of the divergence.

Yeah, I think Microsoft is bluffing. It's not like people who wouldn't take it for free now would be willing to pony up to upgrade later. Microsoft's main goal was to get people on 10 anyway, not the meager amount of money they'd earn from people who wouldn't even bother with 8.x. I just hope...

I definitely don't use subscription-based services like that, but for most people it'll still be better for them to have it if they're interested in keeping updated. I'm still using old versions of Photoshop and Flash (for making graphics, not for web), and of course Office stuff. I just don't...

Re: WANT TO BUY: Surplus Priced Large Aspheric Lens (3 inches diameter or larger).... I don't think there's really any other solution than that truncation and perhaps correction afterwards for the new beamsize + divergence at the aperture. As for the ABCD matrices, you don't have to do them by...

This is too funny! This is a spammer! What great +rep for a spammer! Pro-tip: any time you see one of these inane short messages by some low-post user, with an empty signature below the "__________________", open up the source code view for the webpage and look for the hidden PNG files that...

I remember some friends in Australia telling me about their shitty internet around 2002-2004 or something. The bandwidth transfer caps were like 2-3GB per month or something. I could've transferred more on a 56k modem per month than they could on their bandwidth. The problem was that there...

Re: WANT TO BUY: Surplus Priced Large Aspheric Lens (3 inches diameter or larger).... I'd probably just experiment with the inexpensive stuff to see if it's even feasible to get a good quality beam using such a lens arrangement. The precision lenses will only make it a better spot/beam, but...

Not a bad job! I remember when i was starting out and getting stuff from eBay and all that'd end up happening was that I'd be pleased to see the red laser diode light up, only to see it burn out because I had insufficient heat sinking.

Re: WANT TO BUY: Surplus Priced Large Aspheric Lens (3 inches diameter or larger).... Well, from the description the molded ones are good, or at least sufficient, for collimating light from fibers or fiber optics. They're not those precise CNC-polished types, but you'd be paying $800 or...

It almost looks like metal when it's been hit with a lot of hot sparks from a grinder or something. Have you been doing some metalworking or something that creates sparks?

Re: WANT TO BUY: Surplus Priced Large Aspheric Lens (3 inches diameter or larger).... You can get some for $55-64 from Thorlabs. That's not terrible really. There's this one, that's only 2.1".

Yeah, the subscription based services especially for Adobe products is pretty decent. Often design houses will upgrade their Adobe software as new versions come out, paying $600 or more for Photoshop and Illustrator + some other apps that aren't worth very much in a bundle, or paying $300-400...

Hmm, I was wondering about that too. I did a little poking around and according to this they're "doping" the wire itself, and the blue laser excites it. I guess it's kind of like the white LEDs.

Might be a spammer. I've reported it just in case.

Plus, the laser light source is probably pretty efficient. Even those regular fiber optics look pretty good with a laser compared to other light sources.

EL wire does look pretty cool. Still, after using EL wire a bit, I just don't like it very much, at least for costume lighting and stuff. It's expensive; it's fragile; it eats through batteries (when portable); it needs a specialized driver that sometimes has an annoying ring. Worst of all...

The problem with Firefox is that it's still predominantly a 32-bit application, and it can only allocate up to about 3.5GB of RAM for all the windows that are running. When or if the memory gets used up the entire application crashes as opposed to having a tab get shut down. This used to...

Yeah, you're right. SLI is a pain, and it uses a lot of power too. On my end, I think I'd probably have to upgrade my motherboard and other crap to do that, and that's not something I'll probably do for another few years (10 year build man!) I kind of lament that 4k games are still skirting...

They should, as the current prices are pretty outrageous right now. I'm basing it on the suggested mainstream prices: $600 for the GTX 1080, and $380 for the GTX 1070. So about a $220 price differential, not $250 as I said before (that was based on the Founders Edition). It's still a...

I dunno, an OC'ed 1070 is comparable to a stock 1080 and ~$250 less. Sure, the 1080 can then be OC'ed, but it kind of shows that the 1080 doesn't provide such a huge jump in performance. I can't help but think that the 1080 just isn't worth its performance improvement for that premium. I'd...
