  • Apache redirection problem!!!!

    - by vikas
    Hi guys, I am setting up a pre-built website built in php. The site was actually hosted on the linux server. Now I am trying to set it up on a Window machine with WAMP server. In this website almost every page request passes through a particular file called redirect(which is basically a php file without extension). Now the problem is that when I inspected the configuration(httpd.conf, apache.conf,.htaccess, vhost.conf etc) of the apache server on the linux machine, I nowhere found the redirect rules for doing so. Neither mod_rewrite nor mod_alias rules for this redirection were found there. But is still redirects the request properly. I also noticed that Zend Framework library is there in the exact same directory where the redirect file is. This library is included in the include_path in php.ini. However, the web site is still not developed using Zend MVC and I have seen NO proof of ZEND being used there. So I am really confused how this redirection is working there? I am unable to set up this on window machine without rewrite rules of mod_rewrite or mod_alias. Do you guys know any alternative of both the said modules for redirection? I know the site is really weird, but i have to set it up. :) Thanks in advance for your help.

  • using R.zoo to plot multiple series with error bars

    - by dnagirl
    I have data that looks like this: > head(data) groupname ob_time dist.mean dist.sd dur.mean dur.sd ct.mean ct.sd 1 rowA 0.3 61.67500 39.76515 43.67500 26.35027 8.666667 11.29226 2 rowA 60.0 45.49167 38.30301 37.58333 27.98207 8.750000 12.46176 3 rowA 120.0 50.22500 35.89708 40.40000 24.93399 8.000000 10.23363 4 rowA 180.0 54.05000 41.43919 37.98333 28.03562 8.750000 11.97061 5 rowA 240.0 51.97500 41.75498 35.60000 25.68243 28.583333 46.14692 6 rowA 300.0 45.50833 43.10160 32.20833 27.37990 12.833333 14.21800 Each groupname is a data series. Since I want to plot each series separately, I've separated them like this: > A <- zoo(data[which(groupname=='rowA'),3:8],data[which(groupname=='rowA'),2]) > B <- zoo(data[which(groupname=='rowB'),3:8],data[which(groupname=='rowB'),2]) > C <- zoo(data[which(groupname=='rowC'),3:8],data[which(groupname=='rowC'),2]) ETA: Thanks to gd047: Now I'm using this: z <- dlply(data,.(groupname),function(x) zoo(x[,3:8],x[,2])) The resulting zoo objects look like this: > head(z$rowA) dist.mean dist.sd dur.mean dur.sd ct.mean ct.sd 0.3 61.67500 39.76515 43.67500 26.35027 8.666667 11.29226 60 45.49167 38.30301 37.58333 27.98207 8.750000 12.46176 120 50.22500 35.89708 40.40000 24.93399 8.000000 10.23363 180 54.05000 41.43919 37.98333 28.03562 8.750000 11.97061 240 51.97500 41.75498 35.60000 25.68243 28.583333 46.14692 300 45.50833 43.10160 32.20833 27.37990 12.833333 14.21800 So if I want to plot dist.mean against time and include error bars equal to +/- dist.sd for each series: how do I combine A,B,C dist.mean and dist.sd? how do I make a bar plot, or perhaps better, a line graph of the resulting object?

  • Conditional use of wp_list_categories (Wordpress)

    - by YsoL8
    Hello I am using the wp_list_categories tag in Wordpress. I would like to wrap this in a condition so it is only used when there are posts in the database. Something like: if ($number_of_posts > "0") { } But I can't find a function that'll let me count the number of posts. Anyone know the solution?

  • Check if Ruby object is a Boolean

    - by viatropos
    Can't seem to find how to check if an object is a boolean easily. Is there something like this in Ruby? true.is_a?(Boolean) false.is_a?(Boolean) Right now I'm doing this and would like to shorten it: some_var = rand(1) == 1 ? true : false (some_var.is_a?(TrueClass) || some_var.is_a?(FalseClass))

  • Good memory profiling, leak and error detection for Windows

    - by Fernando
    I'm currently looking for a good memory / leak detection tool for Windows. A few years ago, I used Numega's Boundschecker, which was VERY good. Right now it seems to have been sold to Compuware, which apparently sold it again to some other company. Trying to evaluate a demo of the current version has been so far very frustrating, in the best "enterprisy" tradition: (a) no advertised prices on their website (Great Red Flashing Lights of Warning); (b) contact form asked for number of employeers and other private information; (c) no response to my emails asking for a evaluation and price. I had to conclude that BoundsChecker is now one of "those" products. Y'know, the type where you innocently call and tomorrow 3 men in black suits turn up at your building wanting to talk to you about "partnerships" and not-so-secretly gauge the size of your company and therefore how much they can get away with charging you. SO, rant aside, can anyone recommend an excellent memory checking/leak detection tool, how much it costs, and suggestions for where to buy?

  • So does Apple recommend to not use predicates and sort descriptors in an NSFetchRequest?

    - by dontWatchMyProfile
    From the docs: To summarize, though, if you execute a fetch directly, you should typically not add Objective-C-based predicates or sort descriptors to the fetch request. Instead you should apply these to the results of the fetch. If you use an array controller, you may need to subclass NSArrayController so you can have it not pass the sort descriptors to the persistent store and instead do the sorting after your data has been fetched. I don't get it. What's wrong with using them on fetch requests? Isn't it stupid to get back a whole big bunch of managed objects just to pick out a 1% of them in memory, leaving 99% garbage floating around? Isn't it much better to only fetch from the persistent store what you really need, in the order you need it? Probably I did get that wrong...

  • What was the single byte change to port WordStar from CP/M to DOS?

    - by amarillion
    I was re-reading Joel's Strategy Letter II: Chicken and Egg problems and came across this fun quote: In fact, WordStar was ported to DOS by changing one single byte in the code. (Real Programmers can tell you what that byte was, I've long since forgotten). I couldn't find any other references to this with a quick Google search. Is this true or just a figure of speech? In the interest of my quest to become a "Real Programmer", what was the single byte change?

  • What are some RCP Deployment Options?

    - by mdamman
    We have an RCP application and we are looking for a better way to do installation/updates. Currently to install, they just unzip a zip file. The zip file also contains scripts in it that are not java code. We were running into some bugs when updating if they don't first delete the old folder that was previous unzipped. The issue with deleting the folder is that the user loses the plugin preferences that were set. The installation would also need to register a COM server. The update would have to update the plugins and also replace the current script folder. What are some of the best options that could be used for installing and updating rcp apps? Thanks!

  • php and mysql site design question

    - by Jacksta
    I am trying to build a website with mysql and php. This is the first site I have attempted so I want to write a little plan and get some feedback. The site allows users to add some text in a text field as a “comment”. Once the comment has been entered into the site it is added to the database where it can be voted for by other users. When a new comment has been added to the database it needs to create a new page, e.g. www.xxxxx.com/commentname or www.xxxxxx.com/?id=99981. There will be a list of "Comments" in the database along with the number of votes for each comment. The home page will have two functions. 1) Allow users to add a "comment" 2) Display two tables, each with 20 rows containing most "popular comments" and "recent comments" Each comment will generate its one page where the comment will be displayed. Here users can read the comment and Vote for the comment if they wish. Please help me out by explaining how to do the following. -Generate a new page whenever a comment is added to the database -Add a vote to the vote count in the comment database. -Display the top 20 most popular comments as per number of votes.

  • Are there any guarantees in JLS about order of execution static initialization blocks?

    - by Roman
    I wonder if it's reliable to use a construction like: private static final Map<String, String> engMessages; private static final Map<String, String> rusMessages; static { engMessages = new HashMap<String, String> () {{ put ("msgname", "value"); }}; rusMessages = new HashMap<String, String> () {{ put ("msgname", "????????"); }}; } private static Map<String, String> msgSource; static { msgSource = engMessages; } public static String msg (String msgName) { return msgSource.get (msgName); } Is there a possibility that I'll get NullPointerException because msgSource initialization block will be executed before the block which initializes engMessages? (about why don't I do msgSource initialization at the end of upper init. block: just the matter of taste; I'll do so if the described construction is unreliable)

  • TcpListener problem - re-binding to same port with different local addresses

    - by Zvika
    I'm trying to do the following: listen on some port for loopback connections only, and then start listening on any IP address. Here is the code: TcpListener l1 = new TcpListener(new IPEndPoint(IPAddress.Loopback, 12345)); l1.Start(); Socket s = l1.AcceptSocket(); Console.ReadKey(); //s.Close(); l1.Stop(); TcpListener l2 = new TcpListener(new IPEndPoint(IPAddress.Any, 12345)); l2.Start(); l2.AcceptSocket(); Console.ReadKey(); The problem is that if a client connects while listening on the Loopback address (l1), then no other client can connect to the Loopback address when the second listener (l2) starts listening. why is that? Another thing I noticed is that if I close all clients that connected to l1 (the remarked line), then l2 does accept loopback connections. Any ideas?
