This might not be the type of answer that you're looking for but the issue that has most affected me (running a one-person nonprofit from home) is that I've occasionally had problems because my IP address is shared by "adult" web services because I do not have a dedicated server or address.

And so . . . with my nonprofit's focus on the prevention of teen dating violence I have people in school districts regularly contacting me via email and/or visiting my website from schools. From time to time my IP address used to wind up on block lists and I would spend a fair amount of time contacting school web admins to allow my emails through and/or access to my site.

The host I use (HostGator) has worked well for me but unfortunately does not offer a shared-but-not-with-any-adult-sites hosting plan. What I've done to ameliorate the impact is: (1) use Google's fantastic (and FREE) support for nonprofits by using the free Google Apps service to route all of my email accounts through Google and (2) use a free service to monitor my inclusion on any blacklists (MxWatch Monitor via MxToolbox.com). As a result I've been able to avoid almost all email issues and have been able to address any other blacklisting issues as soon as they crop up.

I don't have the web traffic that you do (approx 5,000 unique visitors daily and less than 50GB monthly bandwidth) but HostGator has been almost completely hassle-free. This is the third hosting company that I've used in the past 7 years and I doubt I'll ever have to switch again. I pay around $20 / month and that includes reseller hosting (I help out a few other sites for small nonprofits that don't have a tech background by hosting their sites for them).

If you need further info feel free to contact me - and if you decide on HostGator I'd be happy to give you a referral code (my org could use any and all financial support possible!!!).

Not sure if anybody has already posted this, but if you'd like to read the article and lack access (and are unwilling to fork over $35) you can read it through the university's website for free: http://www.bcs.rochester.edu/people/Duje/papers/13_Melnick_IQ_CB.pdf

Mr. Yee, what about banning pressure cookers? We've just proved even morons can make effective explosive devices out of pressure cookers!

... but they'll have to walk barefoot across a huge room with a floor littered with thousands of loose legos first!

I'm pretty sure black power is just sulphur, charcoal, and saltpeter... and that's without bothering to even google the recipe. People have been casting their own bullets out of lead for hundreds of years now. Machining your own brass shell casings is probably more trouble than it's worth, but there are literally billions of them already out there, and they are generally reusable. Hardest part to make is the primer, but understand those are made out of mercury fulminate, which my dorm mate made in his room in college -- and he was a computer scientist, not a chemist. Wan't to skip all the complicated stuff, go back to using single-shot muzzle loaders, preferably flintlock. 200 year-old technology pretty easy to replicate today. And most likely pretty easy to make one that won't trigger a metal detector.

Mostly plasting, except for the metal end carrying the primer, and of course the metal shot inside. But yes, I'm sure somebody has by now made non-ferrous ammo to go with the non-ferrous guns that have been around for a long time. In fact, ceramics are pretty strong now. I wouldn't reuse them like brass shell casings, but I'm pretty sure they could be designed to survive a single shot.

Zip guns are single-shot. Printed guns take clips and are multiple shot until they jam, which should happen within the first few clips. Both are fun toys, but nothing I'd bet my life on when a Glock or Walther PPK are still relatively cheap.

Nobody buys a $1000 3D printer to make just one item, just like nobody plants a field of marijuana to get just one joint. Yee doesn't want the people that now go into the drug business to go into the gun illegal gun parts manufacturing business. But Pandora's box is already open, and stuffing everything back inside is now impossible... existing 3D printers can be used to make more 3D printers, in fact most 3D printers come with blueprints to replace easily warn parts and recommend that he first thing you make is spare parts!

Kind of like Restraining Orders... because obviously anybody planning on breaking the existing laws against assault and/or murder is going to totally change their mind when a judge says coming within 100 yards of their intended victim is now against the law!

Practically ALL rapists have male genitalia... let's outlaw having male genitalia!

A homemade gun is a lot less reliable than a cheap firearm, and no harder to trace than any weapon with the serial number filed off. Wait, don't tell Lee that, or next he'll propose outlawing files!

My coworker is a lot smater than Leland Yee-haw, and has figured out that the best way to make knife blades is by taking old hardened carbide steel files and grinding them down. I check his prototype, and yes, it had a much better edge on it than you could possibly get with a 3D printer. And yes, anything you can make with a 3D printer you can make much better with a full machine shop, provided you know what you're doing. When I was in college, my dorm mate went down to the local chemical store and bought everything he needed to make pyrotechnics (ok, the mercury for the mercury fulminate he made was stolen from the college chemstry lab). Kids can't do that anymore, because lawmakers can't tell the difference between pyrotechnics and explosives. Every fireworks display uses mortars, with the same name and principle of operation as the mortars used on the battefield. We now strongly discourage all Americans from learning how to make things for themselves, and as a consequence the Chinese are now much better at machining than we are.

I though .22 gage zip guns were made from car radio antennas... silly me. Yes, some steel pipe would be a lot more sturdy.

Does Leland Lee really not realize you can use a 3D printer to build a 3D printer?!?
