  • How do I indicate success and failure with colour?

    - by Steve McLeod
    I need to make a Java component that turns the background a certain colour when a process passed, and another colour when the process failed. My first thought was: green for success, red for failure. But then I read that 10% of males can't differentiate between these two colours. What would be a better combination of colours? (For the nitpickers: yes, I know that colour alone doesn't suffice, that text, shape, and noise can also be used. Nevertheless I am asking about the appropriate use of colour.)

  • architecture python question

    - by tom smith
    hi. creating a distributed crawling python app. it consists of a master server, and associated client apps that will run on client servers. the purpose of the client app is to run across a targeted site, to extract specific data. the clients need to go "deep" within the site, behind multiple levels of forms, so each client is specifically geared towards a given site. each client app looks something like main: parse initial url call function level1 (data1) function level1 (data) parse the url, for data1 use the required xpath to get the dom elements call the next function call level2 (data) function level2 (data2) parse the url, for data2 use the required xpath to get the dom elements call the next function call level3 function level3 (dat3) parse the url, for data3 use the required xpath to get the dom elements call the next function call level4 function level4 (data) parse the url, for data4 use the required xpath to get the dom elements at the final function.. --all the data output, and eventually returned to the server --at this point the data has elements from each function... my question: given that the number of calls that is made to the child function by the current function varies, i'm trying to figure out the best approach. each function essentialy fetches a page of content, and then parses the page using a number of different XPath expressions, combined with different regex expressions depending on the site/page. if i run a client on a single box, as a sequential process, it'll take awhile, but the load on the box is rather small. i've thought of attempting to implement the child functions as threads from the current function, but that could be a nightmare, as well as quickly bring the "box" to its knees! i've thought of breaking the app up in a manner that would allow the master to essentially pass packets to the client boxes, in a way to allow each client/function to be run directly from the master. this process requires a bit of rewrite, but it has a number of advantages. a bunch of redundancy, and speed. it would detect if a section of the process was crashing and restart from that point. but not sure if it would be any faster... i'm writing the parsing scripts in python.. so... any thoughts/comments would be appreciated... i can get into a great deal more detail, but didn't want to bore anyone!! thanks! tom

  • AVD Screen orientation not changing with CTRL+F11 or CTRL+F12

    - by Brad Hein
    I run my app in the AVD emulator using eclipse but I'm unable to change the screen orientation in the AVD (Android 2.0 platform on the emulator). When I press CONTROL+F11 or CONTROL+F12 on the keyboard, nothing happens. No messages are generated in the adb debuglog/logcat either when I press either hotkey. According to http://developer.android.com/guide/developing/tools/emulator.html these are the correct hotkeys to switch the emulator's screen orientation. I tried it with my app, and with the messaging app. The hotkey has no affect in any case. I'm running Fedora 12, Gnome. I checked my Keyboard Shortcuts in the System - Preferences menu, nothing's attached to either hotkey. Same problem, 3 different PCs (all running Fedora Gnome).

  • Multiple merchant accounts with Activemerchant gem.

    - by sosborn
    I am developing a rails site that will allow a group of merchants (5 - 10) to accept credit card orders online. I plan on using the Activemerchant gem to handle the processing. In this case, each merchant will have their own merchant accounts to handle the payments. Storing banking information like that is not something I am a fan of. This could be solved by queing orders and allowing the merchant to log in to the site, input their credentials and process the order. However, if I go that route then it seems to me that I would have to store the customers' credit card information temporarily until the merchant has the opportunity to log in and process the order, which to me is the greater evil. Has anyone dealt with this situation? If so, what are the options available and what pitfalls should I look out for? In my mind, security customer credit card information is priority number one with the merchant account information a close second.

  • Adding scrollbars to UserControl

    - by Bevin
    I am trying to add vertical and horizontal scrollbars to my UserControl with the HorizontalScroll and VerticalScroll properties, but I am having extreme issues. My problem arises when I drag or manipulate the scroll box on the bar. When I let it go, it simply jumps back to the start position! I know of the AutoScroll property, but I do not want to use it since I want to be able to control every aspect of my scrollbars, and I don't want it to be done automatically. Also, according to the documentation, AutoScroll is for "[enabling] the user to scroll to any controls placed outside of its visible boundaries" which isn't what I want. I just want scrollbars. ...aaand I suppose I could add VScrollBar and HScrollBar to the control, but why should I do this when the scroll functionality already exists? Seems like a waste to me.

  • Linux ext3 readdir and concurrent updates

    - by Wangnick
    Dear all, we are receiving about 10000 messages per hour. We store them as individual files in hourly directories on an ext3 filesystem. The file name includes a sequence number. We use rsync to mirror these files every 20 seconds at another location (via a SAN, but that doesn't matter). Sometimes an rsync run picks up files n-3, n-2, n-1, n+1, and then next rsync run continues with n, n+2, n+3, n+4 and so on. Is it possible that when one process creates files in a certain sequence within a directory, that another process using readdir() sees the files appearing in a different sequence? Kind regards, Sebastian

  • Init modules in apache2

    - by user306963
    Hello, I used to write apache modules in apache 1.3, but these days I am willing to pass to apache2. The module that I am writing at the moment has is own binary data, not a database, for performance purposes. I need to load this data in shared memory, so every child can access it without making his own copy, and it would be practical to load/create the binary data at startup, as I was used to do with apache 1.3. Problem is that I don't find an init event in apache2, in 1.3 in the module struct, immediatly after STANDARD_MODULE_STUFF you find a place for a /** module initializer */, in which you can put a function that will be executed early. Body of the function I used to write is something like: if ( getppid == 1 ) { // Load global data here // this is the parent process void* data = loadGlobalData( someFilePath ); setGlobalData( config, data ); } else { // this is the init of a child process // do nothing } I am looking for a place in apache2 in where I can put a similar function. Can you help? Thanks Benvenuto

  • msmq binding wcf

    - by pdiddy
    I have some messages in my queue. Now I notice that after 3 tries the service host faults. Is this a normal behavior? Where does the 3 times comes from? I thought it came from receiveRetryCount. But I set that one to 1. I got 20 messages in my queue waiting to be processed. The WCF operation that is responsible to process the message supports transaction so if it can't process the message it will throw so that the message stays in the queue. I didn't think that it would of Fault the ServiceHost after a number of retry, is this part documented somewhere? I'm running MSMQ service on my winxp machine. I'm more interested in documentation indicating that the service host will fault after a number of retry. Is this part true?

  • Connection error in java website. Tnsping shows that the service is running

    - by user1439090
    I have a java website application running in windows 7 which uses oracle database for its functionalities. The database has default SID name orcl.

  • What happens when you run out of ram with mlockall set?

    - by James Dean
    I am working on a C++ application that requires a large amounts of memory for a batch run. ( 20gb) Some of my customers are running into memory limits where sometimes the OS starts swapping and the total run time doubles or worse. I have read that I can use the mlockall to keep the process from being swapped out. What would happen when the process memory requirements approaches or exceeds the the available physical memory in this way? I guess the answer might be OS specific so please list the OS in your answer.

  • File upload help in JSP /Struts 1.2

    - by user57421
    Hi All, I have seen lot of reviews and have not been able to figure out how I can solve my problem.. Problem: Currently we have a page to upload the file from local machine to the respositry. It is currently using Struts upload. Now the current requirment is, Since users upload around 1gb of file, they are made to wait for a long time.. So they changed the requirment to browse the file and select the file to upload and hitting upload button should return to the control to next screen imediately.. But the upload process some how needs to be pushed at the backend and should do the upload and send out an email once the upload is complete.. I'm not able to figure out how to transfer the control to next page, when the upload is still running ... any idea or help will be appreicated.. Regards, Senny

  • Microsoft Detours

    I am new to Microsoft Detours. I have installed it to trace the system calls a process makes. I run the following commands which I got from the web syelogd.exe /q C:\Users\xxx\Desktop\log.txt withdll.exe /d:traceapi.dll C:\Program Files\Google\Google Talk\googletalk.exe I get the log file. The problem is I don't fully understand what is happening here. How does detours work? How does it trace the system calls? Also I don't know how to read the output in log.txt. Here is one line in log.txt 20101221060413329 2912 50.60: traceapi: 001 GetCurrentThreadId() Finally I want to get the stack trace of the process. How can I get that?

  • Database on the fly with scripting languages

    - by afilatun
    I have a set of .csv files that I want to process. It would be far easier to process it with SQL queries. I wonder if there is some way to load a .csv file and use SQL language to look into it with a scripting language like python or ruby. Loading it with something similar to ActiveRecord would be awesome. The problem is that I don't want to have to run a database somewhere prior to running my script. I souldn't have additionnal installations needed outside of the scripting language and some modules. My question is which language and what modules should I use for this task. I looked around and can't find anything that suits my need. Is it even possible?

  • Grouping Windows Forms Radiobuttons with different parent controls in C#

    - by Jerry
    Hi, I've got a Windows Forms application in which I have a number of RadioButtons. These RadioButtons are placed within a FlowLayoutPanel which automatically arranges them for me. All RadioButtons that are directly added to the FlowLayoutPanel are grouped, meaning I can select only one of them. However, some of these RadioButtons are paired up with a TextBox so I can supply some argument there. But to have all this arranged properly, I add a Panel control to the FlowLayoutPanel so I can control the alignment of the RadioButton and TextBox relatively to each other myself. These RadioButtons now have their own respective Panels as parent controls and thus are no longer included in the radio group with the other RadioButtons. I read that the the RadioButtons that are in the System.Web.UI namespace have a GroupName property, but unfortunately their System.Windows.Forms counterparts lack this property. Is there some other way I can group these radio buttons are am I going to have to handle onClick events myself? Thanks, Jerry

  • Recreation of MySQL DB using "mysql mydb < mydb.sql" is really slow when the table has tens of milli

    - by Jian Lin
    It seems that a MySQL database that has a table with tens of millions of records will get a big INSERT INTO statement when the following mysqldump some_db > some_db.sql is done to back up the database. (is it 1 insert statement that handles all the records?) So when reconstructing the DB using mysql some_db < some_db.sql then the CPU is hardly busy (about 1.8% usage by the mysql process... I don't see a mysqld either?) and also the hard disk doesn't seem to be too busy... Last time, the whole restore process took 5 hours. Is there a way to make it faster? Such as, when doing mysqldump, can it break the INSERT statement into shorter ones, so that the mysql doesn't need to parse the line so hard when restoring the DB?

  • Multiple Socket Connections

    - by BSchlinker
    I need to write a server which accepts connections from multiple client machines, maintains track of connected clients and sends individual clients data as necessary. Sometimes, all clients may be contacted at once with the same message, other times, it may be one individual client or a group of clients. Since I need confirmation that the clients received the information and don't want to build an ACK structure for a UDP connection, I decided to use a TCP streaming method. However, I've been struggling to understand how to maintain multiple connections and keep them idle. I seem to have three options. Use a fork for each incoming connection to create a separate child process, use pthread_create to create an entire new thread for each process, or use select() to wait on all open socket IDs for a connection. Recommendations as to how to attack this? I've begun working with pthreads but since performance will likely not be an issue, multicore processing is not necessary and perhaps there is a simpler way.

  • Configuring Hibernate logging using Log4j XML config file?

    - by James McMahon
    I haven't been able to find any documentation on how to configure Hibernate's logging using the XML style configuration file for Log4j. Is this even possible or do I have use a properties style configuration file to control Hibernate's logging? If anyone has any information or links to documentation it would appreciated. EDIT: Just to clarify, I am looking for example of the actual XML syntax to control Hibernate. EDIT2: Here is what I have in my XML config file. <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE log4j:configuration SYSTEM "log4j.dtd"> <log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/"> <appender name="console" class="org.apache.log4j.ConsoleAppender"> <param name="Threshold" value="info"/> <param name="Target" value="System.out"/> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%d{ABSOLUTE} [%t] %-5p %c{1} - %m%n"/> </layout> </appender> <appender name="rolling-file" class="org.apache.log4j.RollingFileAppender"> <param name="file" value="Program-Name.log"/> <param name="MaxFileSize" value="1000KB"/> <!-- Keep one backup file --> <param name="MaxBackupIndex" value="4"/> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%d [%t] %-5p %l - %m%n"/> </layout> </appender> <root> <priority value ="debug" /> <appender-ref ref="console" /> <appender-ref ref="rolling-file" /> </root> </log4j:configuration> Logging works fine but I am looking for a way to step down and control the hibernate logging in way that separate from my application level logging, as it currently is flooding my logs. I have found examples of using the preference file to do this, I was just wondering how I can do this in a XML file.

  • How can you calculate the X/Y coordinate to zoom to

    - by Mark
    Im writing a WPF application that has a zoom and pan ability, but what I want to also implement is the ability to zoom and pan "automatically" (via a button click). I have the methods all defined to zoom and pan, but Im having trouble telling the app the desired X/Y coordinates for the panning. Basically, I know that I want the control to be centered at a desired zoom level (say zoomed in 6X times), but the panning destination point is NOT the center point of the control because after the zooming, its been scaled. Does anyone know a way of calculating the desired X/Y position to pan to, taking into account the zooming as well? Do I just scale the desired destination Point? It doesnt seem to work for me... Thanks a lot

  • .Net Compact Framework 2.0 touch and nice controls

    - by eridem
    Hello! I would like to know if somebody knows free custom nice controls for .NET Compact Framework 2.0. There are nice controls as Manila Interface SDK (http://forum.xda-developers.com/showthread.php?t=566188), Sense Interface SDK (http://forum.xda-developers.com/showthread.php?t=648906) and so on for free, but they work only on .NET CF 3.5. Furthermore, there are others that you have to pay for them and for .NET CF 2.0 and 3.5 (Resco or Touch Control Suite). And there is one called Fluid (http://fluid.codeplex.com/) but it's so complicated, there are not exactly controls (are classes added to a host control) and there is not much documentation to work with it. Any nice controls for free and working in .NET CF 2.0? And with list sliders if it's possible? Thanks!

  • Navingating to an .html file in the assembly

    - by Joel
    I’m working with the WPF WebBrowser control to navigate to a html page hosting Silverlight. It seems I cannot use the NavigateToString or NavigateToStream method since I have Silverlight content. The html content loads fine but not Silverlight. So I think I’ll have to use the Navigate method which takes an Uri. Now I html page I’d like to navigate to is in a .html file in my Visual Studio project so I will have to have a local uri of some sort. I don’t want the html file to be copied to the output folder since I don’t want to distribute it separately; I want it to be somehow included in the assembly. The problem is that the WebBrowser control doesn’t seem to allow relative Uris or pack://application: uris. How could I accomplish navingating to an .html file in the assembly?

  • Optimize php-fpm and varnish for a powerfull server

    My setup is: Intel® Core™ i7-2600 and RAM 16 GB DDR3 RAM varnish+nginx+php-fpm+apc for a not very heavy WordPress blog with W3 Total Cache and CDN My problem is that after 55 hits per second according to blitz.io varnish starts giving out timeouts.

  • possible to save pdf with .net from populated form by .fdf

    - by Blair Jones
    I have a process that creates form data in the form of an .fdf file that then has a reference to the .pdf document that is its "parent". is it possible with any .NET process to save that .pdf file (populated with the data that came in from the .fdf)? I need this because I need to email the fully populated .pdf documents out. I've been just sending the .fdfs with fully qualified links to the pdfs, but some people are having problems with it and I'd rather just go full-blown pdf if I can do it. FYI, my server does have a licensed copy of Acrobat installed if that matters....
