Slashdot Mirror


Digital Microfluidics

herrd0kt0r writes "A brilliant team of researches at Duke University have been working on digital microfluidics, with potential applications in biotech labs-on-a-chip, optical routers/switches, wavelength division multiplexers and the like. Essentially, this team has developed a solid state device capable of moving very small drops of fluid over very small distances with very little power. From their website they remark that "[m]icrofluidic processing is performed on unit-sized packets of fluid which are transported, stored, mixed, reacted, or analyzed in a discrete manner using a standard set of basic instructions." Their site includes eight .mpgs demonstrating their microfluidics tech in real-time. Be sure to take a gander at this video showing programmable flow of droplets as well as this one showing droplet splitting and formation."

    Note to moderators : Do not moderate this post down, if you do then you support the editors stance on censorship and you support the end of free speech and support evil organisations like Microsoft, RIAA, MPAA and laws like the CBTBA and DMCA. Moderating this post will only waste mod points, and will not work!

    Slashdot is using censorship! It is trying to eridicate free and open discussion like we know slashdot to be, it has the following RESTRICTIONS in place to Censor you

    They claim they don't, but they do, wonder why their are so many trolls, crapflooders and lamers on slashdot, because they are fighting for their rights! Slashdot is trying to silence the trolls. Remove the filters, the trolls get bored, and slashdot will be troll free!
    • Lameness filters (It blocks a lot of legitmate posts)
    • Unnessary posting delays. Hasnt taco learned to touch type? A lot of posts are typed in less than 20 seconds and it is a ANNOYING DELAY! 2 minute ban? Come on, so some are faster then others, big deal, some people have more to say than others
    • Broken moderation system, The whole point is to sort the gems from the crap, yet a lot of posts designed to make a LIVELY DISCUSSION are MODERATED as flamebait! Come on, not everyone likes X, but just because some one bashes it dosent mean its Flamebait. Flame bait is more useful for DIRECT INSULTS and not legitmate discussions.
    The "troll" moderation reason is fragmented and broken, why? Because they are trying to use an obsolete usenet term on a realtime discussion, "trolls" can cover a huge blanket of ideas.
    • Crapfloods, a meaningless flood of random letters or text, which the lameness filter does a crappy job at trying to stop, besides trolls have written tools using the opensource slashcode to generate crapfloods which bypass the filter
    • Links to offensive websites, the most common one is known a http://www.goatse.cx, a awful site which shows a bleeding anus being stretched on the front page. Trolls sneak these links in by posting messages that look legitimate, but infact are sneaky redirects to the site. Common examples include rd.yahoo.com, www.linux-kernel.tk, goatsex.cjb.net, and googles "Im feeling lucky".
    • Trying to break slashdot, this is actually a good thing, as it helps test slashdot for bugs. Famous examples include the goatse.cx javascript pop-up, the pagewidening post and the browser crashing post!
    Subnet banning, this bans a user unless they email jamie macarthy with their mp5ed ipids. This is unfair, and banning a subnet BLOCKS A WHOLE ISP SOMETIMES, and not that individual user! This can cause chaos! But real trolls use annoymous proxys to get around this so THIS JUST BANS LEGITMATE USERS! Also, they are trying to censor some anoymous proxies, mainly from countrys like africa, so this yet more DISCRIMINATION!

    Pink page of Death, This censors people who use legitmate proxys or firewalls.

    The Bitchslap! An unethical punishment which is applied to moderators who fight censorship against this site! In addition the Editors use their un-limited mod points to create a communist style censored discussion on slashdot!

    But, the issue that concerens us the most, is the COMMENT QUOTA. A discrimatory system that stiffles discussion, cripples the community and will ultimateley destroy slashdot unless it is removed! Annoymous cowards are allowed only 10 posts a day! This is unethical! Users with negative karma only get two! That is DISCRIMINATION! How would you like to only be able to speak once a day, just because of the color of your skin. That would be racism, and slashdot is discrimitating on people just because of a negative number in a database! BOYCOTT SLASHDOT! LET THEM DIE!

    We wan't these stupid useless restrictions REMOVED! This comment will be posted again and again until it does!

    Inportant imformation for users
    Boycott slashdot, they are pissing over their community, they are becoming like the RIAA and MICROSOFT! Do NOT TOLERATE THIS SHIT! Here are some real news for nerds sites. We don't need slashdot, slashdot deserves to die!

  6. It won't save /. by Anonymous Coward · · Score: -1, Offtopic

    Has anybody noticed that MANY of SLashdot's articles are getting progressively worse? I remember, that a few months ago, that many, if not all articles, had about 400 minimum (-1 t o 5). Now, an article is lucky to break the 100 post mark.

    WHat I see, unlike the lies of "bad is dying", is that Slashdot is dying. The evidence to prove that Slashdot is, in fact, dying, is the following:

    1: The Censoring (and deletion) of posts. MS claimed that /. had propeirty material that posters posted. Slashdot, instead, backed down from the 'policy'

    "All trademarks and copyrights on this page are owned by their respective companies. Comments are owned by the Poster."

    Deleting posts set a precident on /. that said "Comments are owned by Editor". The article still exists in Slashdot archives, but as SLashdot's search does not work (half-assed), I am not able to find it.

    2: The INFAMOUS bitchslapping (applying -1 modpoints to a whole thread) of the The first Slashdot troll post investigation [slashdot.org]. And as said on Kuro5hin [kuro5hin.org], "The editors of slashdot seem to be hell-bent on censoring the comment."

    However, posts still flourished in slashdot, even though all other "article sites" watched while Slashdot editors made blunder after blunder. However, point 3 is what is burying Slashdot...

    3: Bans of known "Trolls", ip bans on "abusive users", and only 10 Anonymous Coward posts from each class C subnet. Slashdot is CENSORING the same group that they compalin to when the big media censors all of us. The sad part is that this act is running off more legitimate users than trolls. Wait 10 minutes after an article has been posted and read at -1... All the trolls use http proxies and post anonomously to avoid Slashdot's censoring attacks.

    Now ask yourself..... Why has the amount of posts dropped from 300 per artcile to 100 per article? And no, there wasn't 200 troll posts per article.

      Maybe the .com implosion caused a lot of people to do other things than reading /. at work? :)

      I doubt that /. will truly die for a very long time. Everyone wants news that's 'tailored for them,' and /. is focused on geeks and nerds. Where else will we go for news like this? CNN? _MSNBC?!_ Slashdot truly fills a niche in the media. Also, just because there are fewer posts doesn't mean that things are going downhill. Perhaps people just don't feel like posting as much as they used to. So be it.
