Comment: PFsense hands down (Score 1) 193

PFsense is really at a professional level since 2.0 was released. I've had it on a little box with a Zotac AMD mobo with a 2 port Intel NIC for a couple of years and it's really fantastic. The GUI gives you access to all the knobs you need and the concept of converting all unix config files to one giant XML bundle really works for an embedded router platform. I've got a pretty complex setup & I'm pretty sure I could install & restore the whole thing & its half-dozen packages to a new box in less than half an hour if I had to.

The definitive guide of the time was The Whole Internet User's Guide & Catalog by Ed Krol & published by O'Reilly. I still have a copy of the 2nd ed. on my bookshelf.

Ed was one of the few folks that did the research himself without a pile of other authors' guides lying around as a reference. He had to as there weren't any. Plenty of other guides came after this one, but this was the one the clueful folks had.

Well, I got laid off in VA about 11 years ago (from what was at one time a Nasdaq 100 company) and the notice I got was my boss calling me up with HR on the line, and that day was my last day of employment.

Of course, the company declared chapter 11 about a week later, so it wasn't like the writing wasn't already on the wall.

If this dude knew what he was doing WRT firearm prototyping, he would have "worked up a load" instead of starting out his "testing" with high-velocity varmint ammo.

Just like a handloader, prototyping any firearm (not just 3D printed ones) requires starting with light loads & working up until you start to see signs of excess pressure (deformed cases, sticky bolt, etc), then backing off.

Granted this thing is a rimfire so hand-reloading is not really a practical proposition, but part of the awesomeness of 22LR is that there are a zillion different kinds of ammo out there.

He should have started out with CB caps, then regular 22 shorts, then subsonic 22LR match ammo, then standard velocity, then HV varmint ammo (which is what he started with...), then blow the thing to bits with a max-pressure round like the CCI Velocitor.

Also sense the barrel is made of polymer, hard copper-jacketed bullets are probably a no-no. It would be a good idea to moly lube the thing & keep a chronograph on hand so you know when the effectiveness of the lube is starting to wear off & re-lube it. The better match bullets come pre-lubed so this is another good reason to test with them.

For all we know the thing may work just fine all day long with subsonic match ammo & proper lubrication.

Big kudos for making a 3D printed rifle that actually works, but use good methodology & it might continue to work instead of eventually blowing up every time you take it out...

I still think that in the rifle's present condition he should still blow it to bits with a Velocitor for good measure :-).

Be sure to get a group on paper with the next try...

A bit of googling turns up this cheap IC that would do the job (it's specifically made for running USB or LED devices off of low-voltage power sources).

But kudos to her for making the thing work & winning the prize. Anything that encourages kids to get into STEM is a good thing.

Communism in it's purist form as visioned by Karl Marx has never been implemented; he never really explained it either. But the way I read it, everyone would be equal; no rich, no poor and we all share things -- kind of like Open Source. It's actually not a bad thing if you like the Star Trek way of working not for money, but to better Humanity. It goes back to our Cave Man roots in a way.

Actually the closest implementation to Marx's vision was the Paris Commune that formed in the power vacuum of the early 1870s after the Prussians captured Napoleon III. After losing what was basically a mini-civil war to the Versailles government forces, everyone that was running the Commune was lined up against a wall & executed.

Simplicity does not precede complexity, but follows it.
