  • Reporting Trend Line

    - by Dave Jarvis
    Hi, How would you create a line in JasperReports that follows the trend for the data, in addition to showing the data points? Here are before and after shots: Before After The Time Series report does not appear to have any such option to draw the orange line. (The orange line should be smooth, and thinner, but that's the general idea.) Any ideas how to craft such a report?

  • visually documenting web server configuration and infrastructure

    - by Alex Ciarlillo
    I have just finished a large re-organization and update of our institutions web server(s). This server hosts 3 virtual hosts, 3-4 blogs, 2 wikis, some legacy static HTML pages, and many hosted documents (PDF, .jpg, .xls). I have organized the site into a structure of something like: /var/www/sites/vhost1, vhost2, vhost3 .../wordpress/blogX .../mediawiki/wikiX Data is in a seperate directory structure so I can run a cron task over it to make sure it is all writeable and such. I then symlink to these data directories for each application. /var/www/data/vhost1, vhost2, vhost3 .../wordpress/blogX/uploads .../mediawiki/wikiX/images All Apache configs are in /etc/httpd/conf.d/vhosts.d/vhost1,2,3.conf On top of this there is also a testing server which mirrors this setup. Once changes are fully tested, they are rsynced down to the live server. All the wordpress installs and mediawiki installs are straight form SVN and updates are done by switching branches or "svn up". So my question is how can I best document to share with a) co-workers, b) possible future replacement, c) myself 6 months from now. Obviously I can make a wiki page, excel document, whatever and fill it with text, but I am looking for a more visual representation that I can use to explain the architecture to less-technical people. Ideally it would be awesome if this visual representation could then be expanded to get more technical details.

  • SQL results operation question

    - by wali
    I know I missasked the question, and that's probably the reason I can't find the solution myself: How do I take a result in a stored procedure and and change the data such as if column1 = AAA then column1=Hello else if column1 = BBB then column1 = goodbye and have the data return with the new values? Thanks

  • fastest way to upload an xls file into a database

    - by shmichael
    I have an xls file with ~60 sheets of data. I would like to move them into a database (postgres) such that each sheet's data is stored in a different table. What is the fastest way of creating these tables? I don't care about naming or proper typing of columns. The columns could all be strings for that matter. I don't want to run 60 different csv uploads.

  • Update textarea with jquery

    - by bocca
    Trying to get current data from textarea with jquery and replace it with what server returns. so far q value is picked up right, intead of updating it with server returned content, it just replaces it with ' ' q = $('textarea#id_message').val(); alert(q) $("textarea#id_message").val('&nbsp;').load( '/process/url?html=' + q ); Update just tried it passing server data to test results div, this does work, textarea does not $( '#results' ).html( '&nbsp;' ).load( '/process/url?html=' + q );

  • Is there an equivalent to RSpec's before(:all) in MiniTest?

    - by bergyman
    Since it now seems to have replaced TestUnit in 1.9.1, I can't seem to find an equivalent to this. There ARE times when you really just want a method to run once for the suite of tests. For now I've resorted to some lovely hackery along the lines of: Class ParseStandardWindTest < MiniTest::Unit::TestCase @@reader ||= PolicyDataReader.new(Time.now) @@data ||= @@reader.parse def test_stuff transaction = @@data[:transaction] assert true, transaction end end

  • Reading log files from web application

    - by Egorinsk
    Hi! I want to write a small PHP application for monitoring logs on a Debian server, including syslog logs and Apache/PHP messages. The problem here is that Apache user (www-data) has no access to /var/log directory. What would be the best way to grant an access to logs for PHP application? Let's assume that log files can be really large, like hundreds of megabytes. I have some ideas: Write a shell script that would be run via sudo and tail last 512 Kb of log into a separate file that can be read by application - that's ineffective, because of forking a new process and having to read data twice Add www-data to adm group (that can read logs) - that's insecure Start a PHP process via cron every minute to read logs — that's not very good, because it doesn't allow real-time monitoring. Also, this script will be started even when I don't read logs, and consume CPU time (server is in the cloud, and I'll have to pay for it) Create a hardlink for all log files with lowered permissions - I guess, that won't work because logrotate could recreate log files and they'll change inode number. Start a separate nginx/Apache server under privileged user that may read logs. Maybe anyone got a better solution?

  • What is the easiest to transfer an object between two C# apps over the web?

    - by edude05
    I have written an application that basically gathers up a bunch of text and numerical data from the client PC and stores it as an object. Right now I'm implementing XML serialization so that the file can be saved. The issue is now, how do I get this data to the server? I have a server running IIS 7 setup but I don't quite understand the ASP.net life cycle, so I'm not sure how to implement the receiving app. What should I do? Thanks

  • Using database in Android

    - by Paul
    Does anyone know a good step by step tutorial for using sqlite on Android? I've found this: http://developer.android.com/guide/topics/data/data-storage.html#db and it ok to start with, but then it wants me to jump into other source code then its difficult to follow. I've tried others on the web, one from screaming penguin and that just kept causing errors with JVM. Advice greatly appreciated. I need to: Create database, with several tables (auto id, declare type) update get

  • Ajax progress with PHP session

    - by FFish
    I have an app that processes images and use jQuery to display progress to the user. I done this with writing to a textfile each time and image is processed and than read this status with a setInterval. Because no images are actually written in the processing (I do it in PHP's memory) I thought a log.txt would be a solution, but I am not sure about all the fopen and fread's. Is this prone to issues? I tried also with PHP sessions, but can't seem to get it to work, I don't get why.. HTML: <a class="download" href="#">request download</a> <p class="message"></p> JS: $('a.download').click(function() { var queryData = {images : ["001.jpg", "002.jpg", "003.jpg"]}; $("p.message").html("initializing..."); var progressCheck = function() { $.get("dynamic-session-progress.php", function(data) { $("p.message").html(data); } ); }; $.post('dynamic-session-process.php', queryData, function(intvalId) { return function(data) { $("p.message").html(data); clearInterval(intvalId); } } (setInterval(progressCheck, 1000)) ); return false; }); process.php: // session_start(); $arr = $_POST['images']; $arr_cnt = count($arr); $filename = "log.txt"; for ($i = 1; $i <= $arr_cnt; $i++) { $content = "processing $val ($i/$arr_cnt)"; $handle = fopen($filename, 'w'); fwrite($handle, $content); fclose($handle); // $_SESSION['counter'] = $content; sleep(3); // to mimic image processing } echo "<a href='#'>download zip</a>"; progress.php: // session_start(); $filename = "log.txt"; $handle = fopen($filename, "r"); $contents = fread($handle, filesize($filename)); fclose($handle); echo $contents; // echo $_SESSION['counter'];

  • environment variables generated by at command

    - by Jordan Arseno
    I'm inspecting /var/spool/cron/atjobs/a001cf01570e44 with cat, after running the at command from PHP using exec(). It looks like at has prepended the script with lots of APACHE environment variables. #!/bin/sh # atrun uid=33 gid=33 # mail www-data 0 umask 22 APACHE_RUN_DIR=/var/run/apache2; export APACHE_RUN_DIR APACHE_PID_FILE=/var/run/apache2.pid; export APACHE_PID_FILE PATH=/usr/local/bin:/usr/bin:/bin; export PATH APACHE_LOCK_DIR=/var/lock/apache2; export APACHE_LOCK_DIR LANG=C; export LANG APACHE_RUN_USER=www-data; export APACHE_RUN_USER APACHE_RUN_GROUP=www-data; export APACHE_RUN_GROUP APACHE_LOG_DIR=/var/log/apache2; export APACHE_LOG_DIR PWD=/home/jordanarseno/webroot/public_html/myapp; export PWD cd /home/jordanarseno/webroot/public\_html/myapp || { echo 'Execution directory inaccessible' >&2 exit 1 } curl -k http://localhost/myapp/crons/this_action/3 The last line is the only real command I sent along with at via stdin. What is the purpose of these variables? Where is this procedure stored?

  • Adding a clustered index to a SQL table: what dangers exist for a live production system?

    - by MoSlo
    Right, keep in mind i need to describe this by abstracting all possible confidential info: I've been put in charge of a 10-year old transactional system of which the majority business logic is implemented at database level (triggers, stored procedures etc). Win2000 server, MSSQL 2000 Enterprise. No immediate plans for replacing/updating the system are being considered :( The core process is a program that executes transactions - specifically, it executes a stored procedure with various parameters, lets call it sp_ProcessTrans. The program executes the stored procedure at asynchronous intervals. By itself, things work fine. But there are 30 instances of this program on remotely located workstations, all of them asynchronously executing sp_ProcessTrans and then retrieving data from the SQL server (execution is pretty regular - ranging 0 to 60 times a minute, depending on what items the program instance is responsible for) . Performance of the system has dropped considerably with 10 yrs of data growth: the reason is the deadlocks and specifically deadlock wait times. The deadlock is on the Employee table. I have discovered: In sp_ProcessTrans' execution, it selects from an Employee table 7 times (dont ask) The select is done on a field that is NOT the primary key No index exists on this field. Thus a table scan is performed. 7 times. per transaction So the reason for deadlocks is clear. I created a non-unique ordered clustered index on the field (field looks good, almost unique, NUM(7), very rarely changes). Immediate improvement in the test environment. The problem is that i cannot simulate the deadlocks in a test environment (I'd need 30 workstations; i'd need to simulate 'realistic' activity on those stations, so visualization is out). I need to know if i must schedule downtime. Creating an index shouldn't be a risky operation for MSSQL, but is there any danger (data corruption in transactions/select statements/extra wait time etc) to create this field index on the production database while the transactions are still taking place? (although i can select a time when transactions are fairly quiet through the 30 stations) Are there any hidden dangers i'm not seeing (not looking forward to needing to restore the DB if something goes wrong, restoring would take a lot of time with 10yrs of data).

  • Is a clear and replace more efficient than a loop checking all records?

    - by Matt
    I have a C# List, that is filled from a database.. So far its only 1400 records, but I expect it to grow a LOT.. Routinely I do a check for new data on the entire list.. What I'm trying to figure out is this, is it faster to simply clear the List and reload all the data from the table, or would checking each record be faster.. Intuition tells me that the dump and load method would be faster, but I thought I should check first...

    I load jquery into my greasemonkey script and when the user clicks the start button the script makes a bunch of ajax calls. I then empty body and append data. When i click on something and hit back instead of getting the page post script i lose all the data and need to run the ajax calls again (it can take seconds to run). How do i make it not lose the changes?

  • Getting Run time 1004 error in code

    I tried the code provided by vba express for combining sheet, while execution it is displaying Run Time error 1004: Application Defined or Object Defined Error: My Scenario is: I have a Excel, in that I have first sheet "Connection" and after it I have Sheet1, Sheet2 and so on.
