Well mostly I want a good starting point written by someone who's looked into it (like the DJB ones above). That involves: 1) parts that work together and have been successfully used together, preferably under Linux, by someone other than me; and 2) parts that fit at a good point on the price/performance curve.

Sure, I could dive into separate reviews of every individual component and piece them together myself, but that's more research than I want to do. :)

But I'm thinking of building one again. How exactly does one go about it nowadays? DJB's computer building guides used to be a nice starting point, but he stopped updating them in 2009. Is there something like that, but with current-gen hardware?

(Fwiw, I'm interested more in workstation usage, not a gaming machine.)

When contributors have to invest their credibility in their entries, entries are less likely to be wild untruths.

I'm not sure that's true. There is a lot of total shit in the academic literature, and it's getting worse. And part of the problem is precisely that people's names are attached, so they now have an incentive to game the system. People get promoted based on publications and citation counts. This leads to huge pressure to manufacture them, by any means necessary. There are citation rings out there, people reviewing friends' papers, people falsifying or misconstruing results, etc. Some of them are uncovered, but many aren't. And there are lot more low-level gray-area things going on that are less likely to be uncovered.

Yeah, that's definitely true. A particularly common pattern is that a journalist just cribs something from Wikipedia without researching it, and then Wikipedia cites the news article as if it were an independent source, when in reality it isn't. I'd personally be in favor of tackling this by strongly discouraging the use of news articles as sources, because they typically have extremely poor standards of research. However that leads to other problems, because for contemporary events there is often no other source available, and pushing this too far then runs into the opposite criticism of Wikipedia, that it's too "deletionist". Tricky balance, I think: Wikipedia should cover as much as possible, but should also be as reliable as possible, which are two goals often in conflict.

Especially if you are a professor you should know better. Wikipedia articles cite sources. Well, some of them do. If they don't, you should raise an eyebrow.

If you see a statement in a Wikipedia article that you are thinking of repeating or relying on for something, look first to see: does it cite a source? In this case it did not. In that case, stop here, you should probably not trust the statement. At least not if it's something that matters at all. If it does cite a source, then things are better, but there is still one more step before you should rely on it for anything more than barroom trivia (like, say, publishing an academic paper): you should probably take a glance at that source and see if it really says that.

Incidentally, this will help you use other reference works as well. There are a lot of errors in printed books as well, especially more popular books (those "Who's Who In the Roman World" type books are riddled with incorrect facts). The way to avoid being tripped up by them is to look for references first, and check references second. (How thoroughly to do so of course depends on what you're using the information for.)

Another one in that regard are the museums that feel they have kind of an "advocacy" role. Like a museum dedicated to the heritage of $ethnicgroup, or to a specific only-slightly-famous painter. They often have a big desire to make their topic more well known, so are more likely to go for the maximum-dissemination route.

Comment: interesting split developing (Score 4, Interesting) 24

I see at least three common approaches museums are taking to images of their collections:

1. Maximum lockdown: no photos of the collection on the internet, or at most some very low-res ones on the museum's website. The physical museum itself will typically have anti-photography policies to try to enforce this. The goal is to de facto exercise exclusive rights to reproductions of the work (even where the copyright on the work itself has expired), as a revenue source, through e.g. high-quality art books, licensing of images, etc.

2. Disseminate through museum-owned channels. The museum digitizes its works and makes them available to the general public free of charge, via its own website, in at least fairly high-resolution images, a "virtual collection" that anyone can visit. Third-party dissemination may be possible in certain jurisdictions, but the museum either doesn't encourage or actively discourages it. The goal is to fulfill its public mission of dissemination/education, but while maintaining some control/stewardship of the work even online.

3. Maximum dissemination. The museum digitizes its works and makes them available in as many places as possible under a permissive license: its own website, archival repositories run by nonprofits and state institutions, Wikimedia,, news agency file-photo catalogues, etc. The goal is to fulfill its public mission of dissemination/education as widely as possible, and perhaps also achieve some advertising for the museum's collections and the works/artists it conserves, by ensuring that its works are the ones most likely to be used as illustrative examples in Wikipedia articles, books, newspaper/magazine articles, etc.

The nice thing is all the waste powder can be reused without having to melt it down, so there's almost no waste.

How big of an advantage is that, though? Melting down metal to reuse it is really easy, much easier than with other materials like glass or plastics. Especially in the case where you control the environment and can be assured of its purity, vs. collecting scrap metal or something (but even collecting scrap metal is profitable).

theyre' all hot-shot python hackers but have no idea what the difference between a linked list and an array list is.

Actually I think this is precisely what a lot of non-STEM employers are looking for. When they say they want a computer programmer, what they mean is they want someone who can be the local Excel-macro whiz.

Real knowledge is in books and I hope people do not require a degree to read.

I think that's actually a big part of what many self-taught programmers are missing. It's not the lack of a degree that's the big problem, but the lack of having read any of the things that you would read when getting a degree. You could read them on your own, but many people don't.

Well incubation period is somewhat different. Also an issue, but not the same one as asymptomatic carriers. Some viruses have completely asymptomatic carriers, who can harbor it for years without themselves being significantly affected, which makes long-distance spread a lot easier. Ebola doesn't seem to have that.

Although Ebola does have a reservoir in rats, who carry it asymptomatically. No idea what the odds of it spreading via that route are.

Really this is more about finding a way to collect proxy data for neuroscience, than about studying virtual worlds (despite the /. title). A problem with FMRi studies is that it's often hard to get people to both do what you want to study, and have them be hooked up to the FMRi at the same time. Videogames have the desirable property that people can do things in a "world" while conveniently keeping their head physically parked in the lab.
