  • Recommendations for java captcha libraries

    - by skaffman
    I'm looking for a replacement for JCaptcha, which doesn't seem to be maintained any more, and isn't very good to begin with. The replacement has to integrate nicely with JavaEE webapps. As I can see it, there are three options: JCaptcha - No longer maintained, crude API SimpleCaptcha - much nicer API, nicer captchas, but seems to be Java6 only ReCaptcha - easy to use, uses remote web-service to generate captchas, but not much control over look and feel Has anyone used any others, that they'd recommend?

  • Snort monitoring of spanning interface

    - by aHunter
    I have configured a Cisco 3500 switch with a port SPAN and have my snort node (fedora 13) plugged into it. I am running snort as a daemon and have configured a rule to log all tcp traffic but I am only seeing traffic with a destination of the snort node. I know that the SPAN port is working and wanted to know if there is a specific option that I needed to start snort with in order for it to pickup all the traffic? Or is there something that I have missed here? Many thanks.

  • Filter tagged threads in Thunderbird

    - by Let_Me_Be
    I have a big issue with Thunderbird, I need to process a lot of emails coming from request tracking system. Since only few of those apply to me personally, I tag these threads with appropriate tags. The issue now is that I would like to filter out threads, that do apply to me and those that I haven't tagged yet. I'm unable to do this, because new emails keep arriving into the already existing threads, and of course, these new emails don't get the tags. Basically I would need some sort of filtering rule, that would apply not to a specific message, but the master message in the thread. Is there some possibility to create such filters, or is there some other facility, that would allow me to do the same? Tags are great, since they are actually saved into the messages and correctly sync across multiple machines when using IMAP.

  • Serving web application without Lighttpd/Apache

    - by Shyam
    Hi, As Rails applications default run on port 3000, would it be possible to start the application on port 80? Is it really required to have a fastcgi/mod_proxy enabled web server in front? My users won't be more than three at a time. If so, how would I be able to do so? Thanks!

  • cPanel IPTables custom rules

    - by James Haigh
    Hi, I'm trying to allow a host access to port 3306 by IP. I've added the rule and ran an iptables-save and also service iptables save. These commands show as "OK" with no reported errors. And this works absolutely fine. Now, the server hasn't been restarted at all since I've been having this problem, but every day when I start developing on the server that needs mySQL access, it reports that the connection is refused. Back on the mySQL server, all I need to do is service iptables restart and everything then works as normal. The mySQL server is a CentOS cPanel VPS running on OpenVZ. Anyone know how I can make these rules persist? Is it something cPanel is doing overnight that is messing with my config? Thanks.

  • Automatically inserting new fields in a web.config file

    - by MarceloRamires
    I have an ASP.NET project which has already some custom fields in it's web.config file. I've added in it three more fields and used them in my changes, and it's working great. But where it needs to be used, there aren't these thre fields in the web.config (this was expected, I've just added by hand for tests and developing). How do I check the existance of fields in web.config, and in case of not finding it, how do I add it permanently to the web.config ? Thank you

  • mysql innodb:innodb_flush_method

    - by Daniel
    in the following link http://dev.mysql.com/doc/refman/5.1/en/innodb-parameters.html#sysvar_innodb_flush_method it says:Different values of this variable can have a marked effect on InnoDB performance. For example, on some systems where InnoDB data and log files are located on a SAN, it has been found that setting innodb_flush_method to O_DIRECT can degrade performance of simple SELECT statements by a factor of three. Why O_DIRECT could slow down the select statement?

  • Are comonads a good fit for modeling the Wumpus world?

    - by Tim Stewart
    I'm trying to find some practical applications of a comonad and I thought I'd try to see if I could represent the classical Wumpus world as a comonad. I'd like to use this code to allow the Wumpus to move left and right through the world and clean up dirty tiles and avoid pits. It seems that the only comonad function that's useful is extract (to get the current tile) and that moving around and cleaning tiles would not use be able to make use of extend or duplicate. I'm not sure comonads are a good fit but I've seen a talk (Dominic Orchard: A Notation for Comonads) where comonads were used to model a cursor in a two-dimensional matrix. If a comonad is a good way of representing the Wumpus world, could you please show where my code is wrong? If it's wrong, could you please suggest a simple application of comonads? module Wumpus where -- Incomplete model of a world inhabited by a Wumpus who likes a nice -- tidy world but does not like falling in pits. import Control.Comonad -- The Wumpus world is made up of tiles that can be in one of three -- states. data Tile = Clean | Dirty | Pit deriving (Show, Eq) -- The Wumpus world is a one dimensional array partitioned into three -- values: the tiles to the left of the Wumpus, the tile occupied by -- the Wumpus, and the tiles to the right of the Wumpus. data World a = World [a] a [a] deriving (Show, Eq) -- Applies a function to every tile in the world instance Functor World where fmap f (World as b cs) = World (fmap f as) (f b) (fmap f cs) -- The Wumpus world is a Comonad instance Comonad World where -- get the part of the world the Wumpus currently occupies extract (World _ b _) = b -- not sure what this means in the Wumpus world. This type checks -- but does not make sense to me. extend f w@(World as b cs) = World (map world as) (f w) (map world cs) where world v = f (World [] v []) -- returns a world in which the Wumpus has either 1) moved one tile to -- the left or 2) stayed in the same place if the Wumpus could not move -- to the left. moveLeft :: World a -> World a moveLeft w@(World [] _ _) = w moveLeft (World as b cs) = World (init as) (last as) (b:cs) -- returns a world in which the Wumpus has either 1) moved one tile to -- the right or 2) stayed in the same place if the Wumpus could not move -- to the right. moveRight :: World a -> World a moveRight w@(World _ _ []) = w moveRight (World as b cs) = World (as ++ [b]) (head cs) (tail cs) initWorld = World [Dirty, Clean, Dirty] Dirty [Clean, Dirty, Pit] -- cleans the current tile cleanTile :: Tile -> Tile cleanTile Dirty = Clean cleanTile t = t Thanks!

If I install the app with [console_scripts] option the default path is the current directory. Is there a elegant way to keep the current execution path of the application to the site-packages directory? Thanks
