I feel it necessary to point out, though, that OS X is not a microkernel system comparable to Minix. OS X is largely monolithic, so if one part of the core system crashes, the whole system crashes. Minix 3 is far more ambitious because everything that is not in the (truly tiny) microkernel runs as a separate server process. For example, drivers are running in their own process, so if a driver crashes, the rest of the system can continue running.
To manage the system, Minix has a so-called "reincarnation server" that restarts core system daemons if they go down unexpectedly. It's totally modular and redundant -- far more ambitious and advanced in its design than Linux or OS X. Minix is designed from the beginning to never go down. There is nothing else like that in the Unix world.
This talk by Tanenbaum describes the Minix 3 design in much greater detail:

Finally, have you considered the possibility that your battery might be crap, and that a higher capacity battery that works properly may be the solution, rather than abandoning your entire operating system, or abandoning the entire computer?
Elegant code is...
- Simple -- leveraging the "natural" way to use the programming language
- Compact -- not cluttered with special cases and boilerplate
- Logical -- like secondary documentation, acting as a clear description of how to solve a problem
- Modular -- functions or classes should be clearly grouped as modules
- Easy to understand -- not full of stupid hacks and "clever" tricks
- Reasonably efficient -- performing reasonably well, not at the expense of simplicity
- Maintainable -- any decent programmer could pick up the code without fear and trepidation
- Commented -- some comments should be present, but not too much
- Correct -- it should do what it is meant to do, and only this

The Economist http://www.economist.com/news/... notes, " The economic incentive to marry your peers has increased. A woman with a graduate degree whose husband dropped out of high school in 1960 could still enjoy household income 40% above the national average; by 2005, such a couple would earn 8% below it." And in Slate, http://www.slate.com/articles/... Matthew Iglesias puts it in terms a nerd can related to. "She likes Doctor Who; I like Star Trek...But one thing about us is pretty similar: We both went to fancy colleges full of people with high SAT scores. And in that regard, we’re pretty typical." Perhaps "Natural Selection" is the best explanation for rising college tuition, and increasing student debt."

You may want to read the article before jumping to conclusions. The authors have identified many of the plants and animals as those of the New World, including specific breeds of cattle introduced from Spain, animals like the Ocelot, and others. Their study is very thorough, and it includes study of texts they have found with similar scripts and languages. Their conclusion is that it came from 16th century Spain, and was written in an Aztec language by natives who had been educated by the Spanish (and their evidence for this is quite convincing). From the conclusion of the research:
We note that the style of the drawings in the Voynich Ms. is similar to 16th century codices from Mexico (e.g., Codex Cruz-Badianus). With this prompt, we have identified a total of 37 of the 303 plants illustrated in the Voynich Ms. (roughly 12.5% of the total), the six principal animals, and the single illustrated mineral. The primary geographical distribution of these materials, identified so far, is from Texas, west to California, south to Nicaragua, pointing to a botanic garden in central Mexico, quite possibly Huaztepec (Morelos). A search of surviving codices and manuscripts from Nueva España in the 16th century, reveals the calligraphy of the Voynich Ms. to be similar to the Codex Osuna (1563-1566, Mexico City). Loan-words for the plant and animal names have been identified from Classical Nahuatl, Spanish, Taino, and Mixtec. The main text, however, seems to be in an extinct dialect of Nahuatl from central Mexico, possibly Morelos or Puebla.
I wrote to Timothy some of my recommendations in this comment), and it seems that some major ones have been addressed -- including the layout and amount of text that is visible. I don't know if that was in response to what I wrote, but either way I appreciate it. At this point, fixing Beta must be the most thankless job on Earth.
One other big recommendation I have is to not show pictures by default (icons are okay). Often these images are not directly related to the article, so they are just there to add some color to the screen, at the expense of the article text itself. (1) Maybe it's asking too much for the pictures to simply "go away" if they are unnecessary, but I think that would be positive. (2) Another option might be to default the users who are not logged in to see pictures, while default the readers who logged in to seeing just the text. The idea would be if you are not logged in, you're a peon who enjoys colorful irrelevant pictures, whereas if you are logged in, you just want to read the article. (3) Another possibility, the simplest, would be to resize these thumbnails to be smaller, so they intrude less on the article text. Ideas #1 and #3 would be the simplest approaches.
I think addressing the image thing would be a big improvement to Beta, and is one of the major things at the heart of what all the protest is about. Basically, that Slashdot as a technical site is about text, not just a slideshow of pretty pictures. Slashdot can keep pictures, but they should be resized appropriately since they are not really the point of the site (just colorful distractions).
