Ummm, if you bothered more than a cursory glance at my thing you'd notice I AM advocating open solutions. Monowall is FreeBSD, with some mods and a nice WebUI stuck on it for configuration. EdgeOS, that runs on the ERL, is a fork of Vayetta, which is a fork/mod of Debian.

Both are open solutions but both are under active development and support by a team. Hence I'm a pretty big fan. Monowall was last updated in January, and they still support their legacy version for old hardware like WRAP systems, and their new version for more powerful systems. EdgeOS was updated in March, and they have an alpha for the next version going you can opt in to.

On the other hand the OSS firmwares are half-abandoned it seems. When I Google for Tomato I get a page that talks about it as a WRT54G firmware and looks like it hasn't seen updates in 5-8 years. Further down there's a "Tomato USB" mod on it that was updated in 2010 and still runs on 2.6.

This sort of thing does not engender trust in long term viability or freedom from bugs/exploits.

Also there's the issue that some of us have high speed needs. My Internet connection is 150/20mbps. So I need something that can support that. Triple stream N is pretty much the minimum (dual stream N maybe can in ideal cases) and AC is a better choice. Also the "router" part of the router needs to be able to keep up with that kind of speed, even when I've set up my firewall rules and such.

Finally you seem to confuse reliability with swappability. Sure, you can have a whole host of cheapass old routers and if one dies, put in a new one. However it is hard to do when you need more powerful, and thus expensive, hardware but also that isn't reliable, that is just having extras. I'd rather just have something that has less issues, that works for years on end with no problems, and not have to mess with it. That's what you get with something like a monowall box.

Also like I said, one component may need replacing before others. My Edgerouter Lite will last me a long time, unless it breaks, since it can handle around gigabit speeds with the setup I have (I've tested it). However if I get much faster Internet, I'll need a new cable modem, since mine is only 8x4 stream, and to go much above where I'm at you usually want 16 streams down. Likewise if my WAP is likely to get replaced sooner than the ERL, but probably not as soon as the cable modem.

I can have latest tech where I want it, older tech where I don't and it is all good. Also in my experience setups like that are extremely reliable.

It's a pretty new product, which is why you haven't heard of it. It isn't the greatest thing EVAR, as its web UI could use some work, and some of the features it has can hit the limited CPU pretty hard (VLANs and encryption notably) but it is pretty damn good.

It is what lives at the edge of my home network, and I'm real happy with it.

They also make larger models, should you have the need.

The problem is all those consumer wifi+router deals tend to have kinda crap firmware. While there are, in theory, OSS alternatives they seem to be less than speedy with the updates and support for new hardware.

So I'd look elsewhere. The two things I'd put at the top of your list:

Monowall, on an APU.1C. It is like $150 for the unit, and then $20-30 for an enclosure and CF card. Monowall should support everything you need, it is really feature rich, is pretty easy to use, and the APU.1C is fast enough it shouldn't have issues even with fairly fast internet.

A Ubiquiti Edgerouter Lite. This is a funny looking and named lil' router with quite a bit of performance under the hood, thanks to the hardware routing logic its chip has. $100 and it can push gigabit speeds for basic routing setups. It is also extremely configurable, since it runs a Vayetta fork, which is a Linux OS customized for routing. However to configure the kind of things you want, you might have to hop in to the CLI, I don't know that the GUI has what you need. It supports that though, and you can even hop out of the specialized routing CLI and get a regular Linux prompt where you can install packages and such.

If you want a more supported solution, you could look at a Cisco RV320. Costs like $200 and is a fast lil' wired router (uses the same basic chip as the Edgerouter, just slower). I haven't used one but I'm given to understand you can make them do a lot. Sounds like they firmware may be a little flakey though.

You then just set your consumer WAP+router in to "access point" mode and have it just do the wireless functions.

This is all more expensive and complex than just running on a consumer WAP+router, but more likely to be able to do what you require. It also means you can change out components without as much trouble. Like say your WAP gets flakey, and you want a new one with the latest technology. No problem, just buy it. You don't have to worry if it supports the routing features you need because it doesn't do that for you.

If you are stuck on doing an all in one, then you could look at a Netgear Nighthawk R7000 or the new Linksys WRT1900AC. The Netgear does have bandwidth management and QoS in its native firmware (I haven't played with the features, but I can confirm they are there as I own one) and there is a "myopenrouter" site that has OSS firmware for it (ddwrt mod I think). The Linksys router supposedly is going to have OpenWRT support soon as Linksys worked directly with the OpenWRT team for it.

For one, Slashdot has a bunch of anti-social jerks that like to post, who have an inability to empathize with anyone else. So no surprise they think something like that is a good idea, because they they aren't very reasonable people.

However others have pointed out, accurately I think, that something like this can well be a cause for it. The thing is that if you push someone in to a corner and give them what seems to be no way out, no way to fight back, they may go nuts. Happens with other animals, not just humans. So if you have a kid that is continually picked on, who tries to stand up for themselves, but is then picked on even worse, this time by law enforcement, well then they may well take drastic measures because they feel like there's no option, no hope.

I think there is some real merit to this. Not merit as in saying it is good that kids do it, but that it is correct that actions like this can lead to kids doing it. If they feel they have nothing to lose and nowhere to turn, then a completely crazy overreaction may be the only option they feel they have.

I mean here you have a case of a kid who did everything right, and got increasingly screwed: He never fought back or defended himself, which schools do not allow (you can argue if they should, but they don't, it is against the rules). He got no help or support from the school, I mean it was allowed to happen IN CLASS in front of a teacher. He told his parents, they were skeptical, he produced evidence. He was then threatened by the police, ordered to delete it (illegally), drug to court, etc, etc. So what has he got now? He's been effectively told the bullies are allowed to do as they wish and if you attempt to stop them the police and courts will punish you.

So what's he to do? You can see how a drastic, illogical, action might be what he thinks is his only option. Remember that he doesn't have the perspective of age, he can't look on high school and say "Ya that's a real short time in your life and it gets WAY better once you are out and an adult." To him, this is his whole world. And for that matter, the adult world has stepped in and told him he;s wrong to try and make things better for himself.

As such you can see why people are saying it can lead to something like a school shooting. It is something that administrators need to consider: Dealing with bullying isn't something to do just because it is the right thing (which would be a good enough reason) but it is a safety issue as well.

One of the problems with advanced weapons systems is they require a bunch of effort and facilities to produce, maintain, and use. So while they are fearsome, they are vulnerable to a large force that takes over their support structures.

For example while the US's combat planes are the most amazing the world has ever known, they only work when they have secure airfields to operate from. If those get taken over, they are in a world of shit. Which is why they have security but that security is men with guns. The planes can't defend their own airfields, for many reasons.

If you want to see it on a small scale, well ask yourself why the US has been unable to secure Afghanistan or Iraq. They had considerably more forces than your silly "1 aircraft carrier" scenario, it was hardly the whole population fighting, yet after years and years, they have been unable to secure the countries.

Lots of people with small arms are a force all of their own.

They'll provide ISPs with cache engines for their content. That way, it doesn't use near as much bandwidth. Their content gets pushed to the cache engine, and that streams to the customer. It is win-win since both the ISP -and- Netflix get to use less bandwidth.

So it isn't like the ISPs can whine that Netflix is just too heavy a load. They can get cache engines and call it good. Netflix even picks up the cost of said cache engines near as I know.

Cox does this. They've had fast streaming and "super HD" for a long time because they have Netflix cache engines. Comcast is just being greedy.

Hardware costs money. If you want cheap consoles, you have to trade things off. For example my PC has no problems rendering games like Titanfall at 60fps, even at resolutions beyond 1080 (2560x1600 in my case). So, just put that kind of hardware in a console right? Ya well, my GPU alone costs near double what a current console does, never mind the supporting hardware. It isn't feasible to throw that level of hardware at a console, it just costs too much.

That kind of thing has been tried in the past and it never worked. Remember the Neo-Geo? Had real arcade hardware (back when arcade units had better hardware than home systems) in it, far and above its contemporaries. However with a price equivalent to about $1100 today compared to its competitors which were about $350 in today's dollars it did very poorly.

The console makers had to make tradeoffs, and price was a big concern. Hence the somewhat limited hardware. Basically consoles are for people on a budget. They want something that plays games, but doesn't break the bank. So, the hardware in it has to be scaled accordingly. For those that want performance and are willing to for over more coin, the PC market is happy to oblige.

I'm not sure I agree on the honesty thing either. I see all types. Some are extremely honest, some are shady as hell. Heck we have some professors that basically just milk tenure. They don't teach, don't research, just sit around and collect a paycheck because it is too difficult to fire them. It really runs the gamut.

I like working in an academic environment, but getting shit done isn't the strong suit, particularly standards. You get a bunch of faculty on a committee and it'll take years to decide what to call the damn thing.

Just saying that the claim that the reason the IETF can't move fast is because of corporations as opposed to academics is silly.

So they are a bit different, hardware wise. A big difference is unified memory. There is only one pool of memory which both the CPU and GPU access. That's makes sense since the CPU and GPU are also on the same silicon, but it is a difference in the way you program. Also in the case of the Xbone they decided to use DDR3 RAM, instead of GDDR5, which is a little slow for graphics operations, but the APU (what AMD calls the CPU/GPU combo chips) has 32MB of high speed embedded RAM on it to try and buffer for that.

Ok so there are some differences. However that aside, why the problem with the target? Visual quality. Basically, a video card can only do so much in a given time period. It only can push so many pixels/texels, only run so many shaders, etc. So any time you add more visual flair, it takes up available power. There's no hard limit, no amount where it stops working, rather you have to choose what kind of performance you want.

For example if I can render a scene with X polygons in 16ms then I can output that at 60fps. However it also means that I can render a scene of 2X polygons in about 33ms, or 30fps.

So FPS is one tradeoff you can make. You don't have to render at 60fps, you can go lower and indeed console games often do 30fps. That means each frame can have more in it, because the hardware has longer to generate it.

Another tradeoff is resolution. Particularly when you are talking texture related things, lowering the output resolution lowers the demand on the hardware and thus allows you to do more.

So it is a tradeoff in what you think looks best. Ya, you can design a game that runs at 1080p60 solid. However it may not look as good overall as a game that runs at 720p30 because that game, despite being lower FPS and rez, has more detail in the scenes. It is a choice you have to make with limited hardware.

On the PC, we often solve it by throwing more hardware at the problem, but you can't do that on a console.

I think we need to take a serious look at the "many eyes" theory because of this. Apparently, there were no eyes on the part of parties that did not wish to exploit the bug for close to two years. And wasn't there just a professional audit by Red Hat that caught another bug, but not this one?
