  • Constructor being called again?

    - by Halo
    I have this constructor; public UmlDiagramEntity(ReportElement reportElement, int pageIndex, Controller controller) { super(reportElement.getX1(), reportElement.getY1(), reportElement.getX2(), reportElement.getY2()); setLayout(null); this.pageIndex = pageIndex; this.controller = controller; reportElements = reportElement.getInternalReportElements(); components = new ArrayList<AbstractEntity>(); changedComponentIndex = -1; PageListener p = new PageListener(); this.addMouseMotionListener(p); this.addMouseListener(p); setPage(); } And I have an update method in the same class; @Override public void update(ReportElement reportElement) { if (changedComponentIndex == -1) { super.update(reportElement); } else { reportElements = reportElement.getInternalReportElements(); if (components.size() == reportElements.size()) { if (!isCommitted) { if (reportElement.getType() == ReportElementType.UmlRelation) { if (checkInvolvementAndSet(changedComponentIndex)) { anchorEntity(changedComponentIndex); } else { resistChanges(changedComponentIndex); } return; } } ..................goes on When I follow the flow from the debugger, I see that when update is called, somewhere in the method, the program goes into the constructor and executes it all over again (super, pageIndex, etc.). Why does it go to the constructor :D I didn't tell it to go there. I can make a deeper analysis and see where it goes to the constructor if you want. By the way, changedComponentIndex is a static variable.

  • Is there a way to do a Windows 7 repair install when you are unable to start/boot Windows 7?

    - by irrational John
    My understanding is that the only way to perform a "repair install" in Windows 7 is to run the install setup.exe within the Windows 7 installation you want to repair. This seems a little brain dead to me since usually the reason I wanted to perform the repair install was because the existing installation was so broken that I could no longer boot and use it. It seems Microsoft is saying my only option in that case is to do a clean install and then reinstall all my apps. So I'm wondering if anyone knows of a way to perform a Windows 7 repair install ... one that preserves your existing OS settings and application installs ... on a Windows 7 partition that cannot be booted.

  • Internet explorer and floats: please explain

    - by cletus
    Yesterday someone asked Width absorbing HTML elements. I presented two solutions: one table-based and one pure CSS. Now the pure CSS one works well in Firefox and Chrome but not in IE. Basically the floats are being bumped down to the next line. It is my understanding (and the behaviour of FF and Chrome) that this should not be the case because the left divs are block level elements that floats should basically ignore. Complete code example is below. Adding a DOCTYPE to force IE into standards compliant mode helps slightly but the problem remains. So my question is: am I mistaken about my understanding of floats or is this IE's problem? More importantly, how do I get this to work in IE? It's been bugging the hell out of me. <html> <head> <style type="text/css"> div div { height: 1.3em; } #wrapper { width: 300px; overflow: hidden; } div.text { float: right; white-space: nowrap; clear: both; background: white; padding-left: 12px; text-align: left; } #row1, #row2, #row3, #row4, #row5, #row6 { width: 270px; margin-bottom: 4px; } #row1 { background: red; } #row2 { background: blue; } #row3 { background: green; } #row4 { background: yellow; } #row5 { background: pink; } #row6 { background: gray; } </style> <script type="text/javascript" src="http://www.google.com/jsapi"></script> <script type="text/javascript"> google.load("jquery", "1.3.2"); google.setOnLoadCallback(function() { $(function() { $("div.text").animate({ width: "90%" }, 2000); }); }); </script> </head> <body> <div id="wrapper"> <div class="text">FOO</div><div id="row1"></div> <div class="text">BAR</div><div id="row2"></div> <div class="text">THESE PRETZELS ARE</div><div id="row3"></div> <div class="text">MAKING ME THIRSTY</div><div id="row4"></div> <div class="text">BLAH</div><div id="row5"></div> <div class="text">BLAH</div><div id="row6"></div> </div> </body> </html>

  • How to make RewriteCond+RewriteRule change domain2/folder1 to domain1/folder1

    - by gman
    There's actually 2 questions. One is, how do I make RewriteCond+RewriteRule change domain2/folder1 to domain1/folder1 Actually what I want is any domain that tries to access folder1 that is not domain1 gets switched to domain1. So for example domain2.com/domain1/foo - domain1.com/domain1/foo as well as domain3.com/domain1/foo - domain1.com/domain1/foo This is what I tried RewriteCond %{HTTP_HOST} !^domain1\.com$ [NC] RewriteCond %{REQUEST_URI} ^/folder1/ RewriteRule ^/folder1/(.*)$ http://domain1.com/folder1/$1 [L,R=permanent] But that doesn't work. Next I tried some a simpler rule to see if I could narrow down the issue. RewriteCond ${HTTP_HOST} domain2\.com [NC] RewriteRule ^(.*)$ http://google.com/ [L] I though that would make ANY request to domain2.com go to google.com so I tried http://domain2.com/foo but I get domain2.com/foo not google.com If I go to http://domain2.com I get google. Why don't I get there if I go to http://domain2.com/foo? What am I not understanding about mod_rewrite?

  • Multiple monitors on ATI Radeon HD 5450 1GB DDR2 (Brand: Sapphire)

    - by Robert
    From other posts here, I understand that it might be possible to use up to 3 monitors on this card. My understanding (from the other posts here as well) is that since I have a HDMI output, I do not have a 'DisplayPort', right ? Mine has indeed 3 ports: DVI, HDMI and VGA. Can I have dual-monitor using both the HDMI and DVI ports simulataneously (I am not looking for Eyefinity, but simply extended desktop). Currently I am using dual monitor with DVI and VGA but will replace my 17 inches next week with a new (larger) one that has both VGA and DVI, so I intend to use both monitors connected digitally. I intend to purchase a cable ''HDMI to DVI''(MM) to do so on the second monitor. Optimal resolution on the one I intend to keep (22 inches) : 1680 x 1050, primary monitor. New one (24 inches) has an optimal resolution of 1920 x 1080. Am I running for problems ? Thanks, Rob

  • Strange issue with 64 bit OS

    - by Sherwin Flight
    So I own two versions of Windows 7, one is 32 bit, the other is 64. The 64 bit version came with my new desktop, and the 32 bit version came with my Laptop. I was doing a clean install of my laptop, and the install went smooth, Windows is up and running! However, after installing it I realized that I accidentally used the 64 bit installation disk instead of the 32 bit version. I confirmed this in the System Information screen, it says: System type: 64-bit Operating System As far as I knew this laptop was only a 32 bit machine. My understanding is that a 64 bit OS would NOT run on 32 bit architecture. Am I correct with this assumption? If this was a 32 bit laptop is there any way a 64 bit OS would even run at all on it?

  • Lighttpd mod_rewrite conversion from .htaccess format

    - by hoball
    Hello, I am using lighttpd as webserver and is having an issue about mod_rewrite. Currently I have a set of Apache .htaccess rewrite rules from a PHP script: RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-l RewriteRule ^(.*)$ index.php [QSA,L] In my understanding, if the requested URI is not a file/directory/sym-link, append it to index.php eg. www.a.com/hello/world --> www.a.com/index.php/hello/world I attempted to convert to lighttpd specification: url.rewrite-if-not-file = ( "^(.*)$" = "index.php/$1" ) However, it doesn't work. I suspect that is due to misuse of $1. I tried to use $0/%0 or something else but they fail. Would you please provide me a hint on making the syntax work? Thank you!

  • Can I redeploy Citrix Xencenter Images in Amazon EC2?

    - by Mike Pinch
    Okay - I'm running Citrix Xencenter in my datacenter. My understanding is that Amazon EC2 is a very customized flavor of Xencenter. Based on that, I would like to know whether there is a method to utilize the .VHD disk images generated by Citrix Xencenter in the Amazon EC2 cloud. I realize that I can install tools into the OS and make my own images but that is not what I'm looking for. I'd like the efficiency of taking the images and redeploying them, or at least converting then redeploying. I basically would like to have all my backups running in the cloud, so that is my motivation.

  • How to encapsulate a third party complex object structure?

    - by tangens
    Motivation Currently I'm using the java parser japa to create an abstract syntax tree (AST) of a java file. With this AST I'm doing some code generation (e.g.: if there's an annotation on a method, create some other source files, ...) Problem When my code generation becomes more complex, I've to dive deeper into the structure of the AST (e.g. I have to use visitors to extract some type information of method parameters). But I'm not sure if I want to stay with japa or if I will change the parser library later. Because my code generator uses freemarker (which isn't good at automatic refactoring) I want the interface that it uses to access the AST information to be stable, even if I decide to change the java parser. Question What's the best way to encapsulate complex datastructures of third party libraries? I could create my own datatypes and copy the parts of the AST that I need into these. I could create lots of specialized access methods that work with the AST and create exactly the infos I need (e.g. the fully qualified return type of a method as one string, or the first template parameter of a class). I could create wrapper classes for the japa datastructures I currently need and embed the japa types inside, so that I can delegate requests to the japa types and transform the resulting japa types to my wrapper classes again. Which solution should I take? Are there other (better) solutions to this problem?

  • Missing menu items for Azure SQL tables within SQL Server Management Studio?

    - by Sid
    I have a table (say Table1) that is replicated via SQL Data Sync Agent across a local SQL Server 2012 as well as an Azure SQL Server (part of Microsoft Azure). Everything about Table1 (schema, table values etc ) is identical to the best of my understanding. However, when I list and right click Table1 from Microsoft SQL Server Management Studio 2012 (SSMS), I get some very different menu options, even for seemingly basic stuff. Lets focus only on the 'Design' menu item: It is visible for Table1 on the local SQL server in SSMS It is missing for Table1 on Azure SQL via SSMS It is visible for Table1 (as Open Table Definition) on Azure SQL when reaching it via Visual Studio 2012 (Server Explorer - Data connections) This is seen in the screenshots below: Now I use scripts from some real stuff (esp when I need to check in the SQL scripts etc) but this difference concerns me to some extent. Am I witnessing just a tools artifact in SQL Server Management Studio when connecting to Azure SQL? or is it something more serious about limitations of Azure SQL itself (although, just seeing the Design surface is so basic!)?

  • Troubleshooting "connection reset" error on my linux server

    - by Chris
    I fervently hope someone here can help me with the problem I am experiencing. I am a programmer, and I have very little understanding of linux sysadmin terminology/concepts. I am attempting to troubleshoot a problem with my website. It is a Facebook app, and whenever I try to connect using Chrome, I get an error stating that the "connection was reset". I have been Googling for four days straight trying to find a solution to this problem, but no joy. A big part of the problem is that I do not understand the terminology being employed, and the output from many of the tools referenced is likewise indecipherable to me. I am running a VPS with CentOS 5, apache, PHP, and MySQL. I could spam this post with a ton of information from my iptables, apache, etc but if anyone needs information from my server, please let me know how to get it, and I will post it here. Thank you for any help you can offer!

  • startup cassandra layout

    - by davidkomer
    We've got a relatively low-traffic site (~1K pageviews/day) hosted on a single server, and expect it to grow significantly over the next few years. I'm thinking of moving over to Rackspace CloudServer or EC2 and firing up 3 nodes (all on CentOS): 2 x Web (Apache) - with loadbalancer 1 x MySQL (for the Wordpress powered part) The question is where to put Cassandra right now... Should it sit on each Web node, or the MySQL node? My thought right now is to put it on Web nodes. It's my understanding that Cassandra has the benefits of fault-tolerance (i.e. if we take a node down, the site is still operational). So even with only 2 nodes, we'd have that benefit as opposed to just putting it on the MySQL node. Also, as we scale up and add another node, a cassandra instance can come along with it and the php can always run its queries on localhost. Is this a good idea?

  • Windows 7: Use VirtualStore technology as user for own benefit?

    - by mfn
    I've researched a bit and came to the understanding that VirtualStore is part of the new UAC feature in Vista/W7 which is the file system part of the transparent data redirection and redirects write access to folders like program files to C:\User\<username>\AppData\Local\VirtualStore\ in lack of applications respecting the LUA principles. Now I'm interested if that kind of transparent redirection can also be used as a power to the user. Here's an example which comes to my mind: I install any kind of software to e.g. D:\Whatever\ThisAndThisApp\ and I set up things that, after initial installation, any write access to this folder is transparently redirected to e.g. D:\MyOwnVirtualStore\Whatever\ThisAndThisApp\file_only_writable_here.txt. Is this thinking too far or can I actually use that power of VirtualStore as a user on Windows 7? I'm using the Professional version of that matters.

  • PEAR:DB connection parameters

    - by Markus Ossi
    I just finished my first PHP site and now I have a security-related question. I used PEAR:DB for the database connection and made a separate parameter file for it. How should I hide this parameter file? I found a guide (http://www.kitebird.com/articles/peardb.html) that says: Another way to specify connection parameters is to put them in a separate file that you reference from your main script. ... It also enables you to move the parameter file outside of the web server's document tree, which prevents its contents from being displayed literally if the server becomes misconfigured and starts serving PHP scripts as plain text. I have now put my file in a directory like this /include/db_parameters.inc However, if I go to this URL, the web server shows me the contents of the file including my database username and password. From what I've understood, I should protect this file so, that even though PHP would be served as text, nobody could read this. What does outside of web server's document tree mean here? Put the PHP file out of public_html directory altogether deeper into the server file system? Some CHMOD?

  • How to schedule a biweekly cronjob?

    - by Roman
    crontab(5) defines the following fields: field allowed values ----- -------------- minute 0-59 hour 0-23 day of month 1-31 month 1-12 (or names, see below) day of week 0-7 (0 or 7 is Sun, or use names) and explains: Step values can be used in conjunction with ranges. Following a range with ``/<number>'' specifies skips of the number's value through the range. For example, ``0-23/2'' can be used in the hours field to specify command execution every other hour (the alternative in the V7 standard is ``0,2,4,6,8,10,12,14,16,18,20,22''). So, no biweekly Jobs, as far as my understanding goes. I'm quite sure there are workarounds, what are yours? Or did I miss something?

  • Excluding certain file types in wget

    - by Alan Spark
    I have been using wget for a while now to mirror files from an ftp server to a local folder. My wget command is as follows: wget -mirror -w 1 -p -nH -P /var/www/ ftp://my-ftp-server However, I just noticed that it is copying over a .listing file for every folder that it visits. So, even if nothing has been changed on the ftp server, a .listing file will always be copied. My understanding is that the .listing file is created when wget opens the ftp session. Is there a way to avoid this? I've tried the -R option (e.g. -R .listing) but this didn't help. See: http://www.gnu.org/software/wget/manual/wget.html#Recursive-Accept_002fReject-Options Thanks, Alan

    Hi all, here's my case, I have set up a share in a virtual windows server 2008 R2, the server is hosted by GoDaddy my question is, how do I access the server's public folders, I need to open a file locally (on the client) and to do that I need the server to show up in my Network locations, I have the right credentials and have created a special group that has access to the particular folder that I'm sharing the problem is I don't know how to add the server to my network locations. I have tried VPN Connection but it is my understanding that it cannot be done since it is virtual share server. Any help is trully appreciated.

  • How to address an EC2 instance from both inside and outside datacenter?

    - by Alexandr Kurilin
    I'm trying to find a good way of being able to address my EC2 database instance from both inside and outside of the datacenter. Other EC2 instances need to be able to call into it, and other clients like pgAdmin might need to connect to it from the outside world as well. It's my understanding that using the internal and external DNS names is sustainable long term as each reboot leads to a change. I'm thinking of associating an Elastic IP with the instance and giving it an A record (say db1.mydomain.com) which I then will use both within and outside the datacenter. Further instances in the same role will get the same treatment and a DNS record of db2.mydomain.com etc. Now, is there a cleaner and more stable way of achieving this result? Am going about this the wrong way? Suggestions?

  • Recursion through a directory tree in PHP

    - by phphelpplz
    I have a set of folders that has a depth of at least 4 or 5 levels. I'm looking to recurse through the directory tree as deep as it goes, and iterate over every file. I've gotten the code to go down into the first sets of subdirectories, but no deeper, and I'm not sure why. Any ideas? $count = 0; $dir = "/Applications/MAMP/htdocs/idahohotsprings.com"; function recurseDirs($main, $count){ $dir = "/Applications/MAMP/htdocs/idahohotsprings.com"; $dirHandle = opendir($main); echo "here"; while($file = readdir($dirHandle)){ if(is_dir($file) && $file != '.' && $file != '..'){ echo "isdir"; recurseDirs($file); } else{ $count++; echo "$count: filename: $file in $dir/$main \n<br />"; } } } recurseDirs($dir, $count); ?

  • One bigger Virtual Machine distributed across many Nodes [on hold]

    - by flyer
    I just setup virtual machines on one hardware with Vagrant (this is just a test environment, not production!). I want to use a Puppet to configure them and next try to setup OpenStack. I am not sure If I am understanding how this should look at the end. Is it possible to have below architecture with OpenStack after all where I will run one Virtual Machine with Linux? ------------------------------- | VM | ------------------------------- | NOVA | NOVA | NOVA | ------------------------------- | OpenStack | ------------------------------- | Node | Node | Node | ------------------------------- (In my environment Nodes are just virtual machines, but my question concerns separate Hardware nodes) After some comments... Is it a language barrier, or? This is only my 'virtual environment'. If we imagine this virtual machines are a separate Nodes (e.g. every has 4 cores) the OpenStack is still the same, right? Can I run one Virtual Machine across many Nodes with OpenStack? Is it possible to aggregate the computation power of separate machines in one virtual distributed operating system?

  • Background process and SIGHUP

    - by Charles Salvia
    My understanding is that a program that is associated with a terminal will receive the SIGHUP signal if that terminal is closed. This usually will terminate the program. I also know that you can use the nohup command along with the & symbol to run the program in the background, and disassociate it from the terminal so that the program is not terminated when the terminal closes (on log out.) However, suppose a program is run normally without nohup, but is then suspended using Cntl-Z. If the program is then resumed in the background using the bg command, will it receive the SIGHUP signal on log out? Or to put it another way: if I have a program which is already running, and I don't want to stop it but I'd like to log out, can I suspend it using Cntl-Z and run it in the background using bg? Or will the program be terminated when I log out?

  • Explanation of nodev and nosuid in fstab

    - by Ivan Kovacevic
    I see those two options constantly suggested on the web when someone describes how to mount a tmpfs or ramfs. Often also with noexec but I'm specifically interested in nodev and nosuid. I basically hate just blindly repeating what somebody suggested, without real understanding. And since I only see copy/paste instructions on the net regarding this, I ask here. This is from documentation: nodev - Don't interpret block special devices on the filesystem. nosuid - Block the operation of suid, and sgid bits. But I would like a practical explanation what could happen if I leave those two out. Let's say that I have configured tmpfs or ramfs(without these two mentioned options set) that is accessible(read+write) by a specific (non-root)user on the system. What can that user do to harm the system? Excluding the case of consuming all available system memory in case of ramfs

  • Logging off does not kill process in Windows Server 2003

    - by user25951
    I have a Windows Server 2003(Enterprise, SP2). My understanding was that any process created by a user will be terminated when the user loggs off the account. But its not happening. I login via Administrator account. Start a simple java process and logoff. But the process is not killed. Is there any configuration for this or something? I am mostly a software programmer and not much in to servers and so I am stuck. I found out that while logging off, 1) Win32 is supposed to send a CTRL_LOGOFF_EVENT to all processes started by that user. 2) JVM is supposed to handle this event and terminate the VM. But I can't understand why my java process is not killed when i logoff. Any idea!!!

  • Processing files from a Content Distribution Network problem

    - by Derek
    From what I understand that CDNs are meant to physically cache your static files in multiple regions closer to your users. However, I've noticed a few websites that when a page is requested from their server, they grab the asset files from their cdn, process them (compress, minify, etc.) cache the results on their server and then send them to the user requesting the page. This doesn't make too much sense to me. Wouldn't processing the files on your server eliminate the gains from using a cdn? Is this a normal way of doing things, or am I not understanding the whole asset management concept?

  • getting data from dynamic schema

    - by coure2011
    I am using mongoose/nodejs to get data as json from mongodb. For using mongoose I need to define schema first like this var mongoose = require('mongoose'); var Schema = mongoose.Schema; var GPSDataSchema = new Schema({ createdAt: { type: Date, default: Date.now } ,speed: {type: String, trim: true} ,battery: { type: String, trim: true } }); var GPSData = mongoose.model('GPSData', GPSDataSchema); mongoose.connect('mongodb://localhost/gpsdatabase'); var db = mongoose.connection; db.on('open', function() { console.log('DB Started'); }); then in code I can get data from db like GPSData.find({"createdAt" : { $gte : dateStr, $lte: nextDate }}, function(err, data) { res.writeHead(200, { "Content-Type": "application/json", "Access-Control-Allow-Origin": "*" }); var body = JSON.stringify(data); res.end(body); }); How to define scheme for a complex data like this, you can see that subSection can go to any deeper level. [ { 'title': 'Some Title', 'subSection': [{ 'title': 'Inner1', 'subSection': [ {'titile': 'test', 'url': 'ab/cd'} ] }] }, .. ]
