  1. It is jealousy on Women Increasingly Freezing Their Eggs To Pursue Their Careers · · Score: 3, Insightful

    Most people who say "Oh it is selfish not to have kids," are jealous. Kids are a big commitment, you have to trade off a lot to have them, at least if you are going to be a good parent. Now there are benefits, of course, it can be extremely rewarding emotionally. But there are tradeoffs and some people don't like them. So they see childless couples and see all the extra money and time they have and get jealous, and thus hateful.

    It is, in fact, not a selfish position. It is a very pragmatic one. If we are to have a sustainable future, we need population growth to level off. Now I suppose we could go about it all draconian like China and force people to have a certain amount of children. However a better solution is for people who don't wish to have children to not do so. That allows those that want to have more children to do so and yet maintain a consistent population level.

    Labour is a big part of the cost of pretty much anything you buy. Software is the ultimate example. The materials and distribution cost of software is minimal even if done on physical media. However that doesn't mean it is free to produce. It takes a lot of labour, in the form of programmers writing the code, QA testers reviewing things, support staff, and so on, to make the product happen.

    Physical devices are no different, they just have higher materials costs. However all the labour cost is there. People had to design, build, test, etc, etc, that product and they all need to be paid since they all like to eat, have a place to live, and all that jazz.

Anyone with basic MSE knowledge knows that there's a big difference between what you can potentially extrude using a process like a 3D printer does and how you have to make other various materials. It isn't as simple as just printing metal (which I've no doubt we'll see soon), not all metal processes are created equal.

It probably would do faster, it's CPU wasn't fully loaded, that is just as fast a test server as I could easily get to.

    Also all of this assumes you can get a visa and get admitted. People from other EU nations, no problem, you can live and work anywhere in the EU, that is a big part of what the treaty means. Non-EU individuals have to get a student visa, the requirements of which vary.

    And of course none of that deals with the cost of food, housing, transport, etc. You are on your own for that, barring a scholarship.

    This is a subject I have more than a passing familiarity with, as my sister is currently working on her PhD in Europe (at two universities, one in the EU one outside of it).

    Grad school was historically and is supposed to be the sort of thing not everyone does. It is for people who are really interested in a field, who want to start doing some original research (under the umbrella of a professor's overall research) and so on. The sort of thing only for those that are truly interested in pursuing the subject more deeply and pushing the boundaries.

    Also most fields don't require graduate degrees. There are some that do (like lawyers), though usually they require a PhD or other advanced degree after it (like professors, medical doctors, etc). However for most an undergraduate degree is all they are after.

    However where I work, I see a ton of students that go in to grad school that are hoop jumpers. They see it as the next thing, that will get them a better job. They aren't that interested in the work, and don't have a particularly good understanding of it. They take comprehensive exams instead of doing a thesis, and so on. They try and use more time in school to make up for a lack of talent.

    So, if you are thinking of grad school, and it'll be any kind of financial hardship ask yourself: Why am I going? If it is because your field requires it, then ok no problem. Gotta do what you gotta do. If it is because you really love the field and you want to go to a higher level, that's good too, but just understand it'll be a pain financially. If it is "because I'll get a better job," then no, stop right there. That's not a reason to go to grad school, particularly if it is going to be a problem financially. It probably will NOT get you a better job, and will just give you more debt.

    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.

    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.

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.

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.

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.

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.
