  • Why does Oracle SQL Developer take so long to open?

    - by oscilatingcretin
    I think anyone who's used Oracle SQL Developer will agree that it's painfully slow on the load. My research has lead me to a solution that seems to have helped a little, and that's telling OSQLD not to check for updates on startup. However, it still takes several minutes to open. What could OSQLD possibly be doing during load time? Is there any way get it to open right away? Edit: Adding potentially relevant system specs: CPU: Intel i5-2520M 2.5 ghz Windows 7 32-bit RAM: 4 gb

  • Why does Exim puts emails on hold if there are frozen messages in the queue?

    - by user51932
    I've a CentOS with CPanel server working as a SMTP server, which currently uses 20 different hostnames and IP addresses to deliver email for an email newsletter service. However, it's extremely slow in sending emails. It's sending like 10 emails per minute, which I check by running the "exim -bpc" command. What could be affecting this? One thing I'm supposing, is that there are frozen messages in the queue, which are slowing down the sending until they're sent out, and are putting new messages on hold. What are the most common reasons a message can get frozen? Also, would it be more efficient to use 20 different small VPSs to send out email rather than use one large VPS with the 20 different hostnames and IPs in it?

  • encoding movies for the web

    - by ELS
    Hi All, I have a friend that hosts his website on IIS and Windows Server 2003 R2 32-bit. He has .WMV files and .MPG and others and some of these are 30 mb in size! He wonders why users complain the site is slow! So my question is how can we reduce the size of these movies? What software? What settings for bit-rate, etc? Is there free software? I can use either a Mac or a PC. Thoughts are appreciated.

  • Windows screen resolution change: lengthen timeout

    - by Jonathan J
    Occasionally I need to change the screen resolution of the console of a Windows virtual machine using XenCenter. When you attempt this change, Windows will revert if you don't accept the changed resolution within 15 seconds of clicking 'apply.' (Normally, this is a good thing.) The problem is that if I have a slow connection between XenCenter and the Xen hypervisor, the virtual console display may not refresh quickly enough to allow me to respond within 15 seconds. As a result, I can't change the resolution, even though the new resolution is valid. Is there a way to increase the timeout before reverting to the original display resolution?

  • Unable to insert DateTime format into database

    - by melvg
    I'm unable to insert the DateTime into my database. Am i writing the statement wrongly? Apparently without the DateTime, I am able to insert into the database string dateAndTime = date + " " + time; CultureInfo provider = CultureInfo.InvariantCulture; DateTime theDateTime = DateTime.ParseExact(dateAndTime, "d MMMM yyyy hh:mm tt", provider); //Create a connection, replace the data source name with the name of the SQL Anywhere Demo Database that you installed SAConnection myConnection = new SAConnection("UserID=dba;Password=sql;DatabaseName=emaDB;ServerName=emaDB"); //open the connection ; myConnection.Open(); //Create a command object. SACommand insertAccount = myConnection.CreateCommand(); //Specify a query. insertAccount.CommandText = ("INSERT INTO [meetingMinutes] (title,location,perioddate,periodtime,attenders,agenda,accountID,facilitator,datetime) VALUES ('"+title+"','" + location + "', '" + date + "','" + time + "', '" + attender + "','" + agenda + "', '" + accountID + "','" + facilitator + "','" +theDateTime+ "')"); try { insertAccount.ExecuteNonQuery(); if (title == "" || agenda == "") { btnSubmit.Attributes.Add("onclick", "displayIfSuccessfulInsert();"); //ScriptManager.RegisterStartupScript(this, GetType(), "error", "alert('Please ensure to have a title or agenda!');", true); } else { btnSubmit.Attributes.Add("onclick", "displayIfSuccessfulInsert();"); Response.Redirect("HomePage.aspx"); //ScriptManager.RegisterStartupScript(this, this.GetType(), "Redit", "alert('Minutes Created!'); window.location='" + Request.ApplicationPath + "/HomePage.aspx';", true); } } catch (Exception exception) { Console.WriteLine(exception); } finally { myConnection.Close(); } It does not insert the SQL into my database.

  • How do I change HOMEDRIVE HOMEPATH and HOMESHARE in Windows XP?

    - by user26034
    I have got a laptop which is configured to have the user profile in a network drive. This is causing me a lot of headaches since the connectivity to my company is very slow. I want to relocate the profile of my user into a local directory. How do I do that? Those are the settings at the moment: C:\>set HOME HOMEDRIVE=P: HOMEPATH=\ HOMESHARE=\\SOMESERVER\_myuser$ The drive P is a network drive mapped to HOMESHARE. I can't find where windows is setting those environment variables, not even in the registry. The laptop is running Windows XP.

  • Different versions of 2.5" drives? Unscreawing Intel 320 for slimmer drive to fit newer thinkpads?

    - by hhh
    My x60s laptops come with about 1-2mm heigher 2.5" HDD than newer x220 models. This is totally stupid when one would like to reuse the old drive in the newer laptops. I bought newer 2.5" 320 Intel SSDs and they seem to have such 1-2mm gap to unscrew but I am unsure whether it is meant for opening. Could someone instruct what to do here? Look the manufacturer has started changing the old good 2.5" drives into slightly different versions, now it means slow compability issues to fix or totally new 2.5" drives. Ideas how to proceed? Unscrewing newer 320 drives or are some other versions of 2.5" drives meant for x220? Does there exist some sort of racks to get drives working between different comps? Perhaps booting from laplink is currently the easiest solution to get things working when changing harddrives between comps? Perhaps related http://www.zdnet.com/blog/hardware/seagate-announced-super-slim-25in-momentus-thin-hard-drive/6439

  • Application or plugin for turning screenshots into searchable text?

    - by Software dood
    It's a common practice in our company that people take screenshots of any software error situation they get into, and then they paste the screenshots in mail messages and/or Word documents that get sent and forwarded back and forth. I have lots of stuff like this in my Outlook mail archives, and the problem with it is, the screenshots aren't searchable, because they're just dumb images as far as Outlook or Windows Search are concerned. Sometimes I edit the original mail messages and type the text (typically an error message) from the screenshot into the message, but quite rarely, because it's slow and prone to typing errors. Is there a program or Outlook or Windows plugin that would OCR and index images in the Outlook mail archives, so the image contents would become indexable?

  • WCF with MANY database connections

    - by Jorge Dominguez
    I'm working in the development of an ERP type .Net WinForms application consuming a WCF service. It's to be used by many small companies (in the range of 100-200). Database is SQL Server 2008 and the service will be hosted as a Windows service. Even thought there will be a single DB Server, our customer insists in having separate databases for each company. That is because of stability/support concerns (like DB being damaged or took offline for some reason thus affecting all clients). Concerns coming from previous experiences (not necessarily with same platform). With a single database, connections to the DB would be opened at service start up and pooling used, but, I'm not sure how connections could be managed in a multiple DB scenario: Could a connection to the corresponding DB be opened and closed for each service request? would performance be acceptable? If a connection is opened and maintained for each company accessing the system, what's the practical limit of opened connections (to different databases)? It would be very interesting to hear your opinions and suggestions for this situation. Tanks

  • Applications starts very slowly from a network path

    - by Snowfox
    Hi We have a windows 2008 server which hosts the network share \\srvcompany\lib. This share contains several applications needed for the daily business. Every client/user (all win xp) has shortcuts on the desktop to these apps. We have the problem that at several (but not all) clients the apps starts very slowly. If I copy the application's programm files to a local folder then they'll start fastly. When I watch the memory usage in the task manager on such a "slow" machine while an applications starts I notice that the memory usage grows much slowier than when I start the app from a "fast" machine. But when I copy files with Windows Explorer from this share, the speed is nearly the same. I've also checked the network driver, both tested clients have the same network card with the same driver version. Has anyone an idea where or what I should check next to solve this problem? Thanks for answers.

  • Monitor windows startup process

    - by vlad-ardelean
    My win7 starts up pretty slow lately. I think it's some kind of malware, but my antivirus software doesn't pick up anything. How could i monitor the startup processes myself? It seems to me like either something's doing a lot of work, or some important windows process hangs for a while, since there's stuff that i can do while it's starting (like start a console), and stuff that i can't do (like execute the systeminfo command in the console) So if you happen to know how i can monitor my system, that would be great. Thx, you guys rule.

  • symfony + doctrine + inheritance, how to make them work?

    - by imac
    I am beginning to work with Symfony, I've found some documentation about inheritance. But also found this discouraging article, which make me doubt if Doctrine handles inheritance any good at all... Has anyone find a smart solution for inheritance in Symfony+Doctrine? As an example, I have already structured the database something like this: CREATE TABLE `poster` ( `poster_id` int(11) NOT NULL AUTO_INCREMENT, `user_name` varchar(50) NOT NULL, PRIMARY KEY (`poster_id`), UNIQUE KEY `id` (`poster_id`), ) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=latin1; CREATE TABLE `user` ( `user_id` int(11) NOT NULL, `real_name` varchar(50) DEFAULT NULL, PRIMARY KEY (`user_id`), UNIQUE KEY `user_id` (`user_id`), CONSTRAINT `user_fk` FOREIGN KEY (`user_id`) REFERENCES `poster` (`poster_id`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1; From that, Doctrine generated this "schema.yml": Poster: connection: doctrine tableName: poster columns: poster_id: type: integer(4) fixed: false unsigned: false primary: true autoincrement: true user_name: type: string(50) fixed: false unsigned: false primary: false notnull: true autoincrement: false relations: Post: local: poster_id foreign: poster_id type: many User: local: poster_id foreign: user_id type: many Version: local: poster_id foreign: poster_id type: many User: connection: doctrine tableName: user columns: user_id: type: integer(4) fixed: false unsigned: false primary: true autoincrement: false real_name: type: string(50) fixed: false unsigned: false primary: false notnull: false autoincrement: false relations: Poster: local: user_id foreign: poster_id type: one User creation for this structure with Doctrine auto-generated forms does not work. Any clue will be appreciated.

  • Is it possible to have tab completion of drop-down lists in web pages in Firefox?

    - by Nick Booker
    Does anyone know of a Firefox plugin that would enable tab-completion (or some other key sequence like Alt-L) of items in drop-down lists in web forms? e.g. ou<TAB>in<TAB>s<TAB> for 'OurCompany - Internal Support' Vimperator's hints mode makes it very ergonomic to focus the drop-down list with a key sequence like f13 but the keyboard interface to the drop-down list still sucks. I very frequently have to pick items from a very long list with very long common prefixes among the entries (e.g. 30-40 starting with OurCompany -), which renders both the built-in keyboard interface and the mouse pretty slow and unergonomic. I basically want readline support for filling webforms!

  • Debug website on host from virtual machine

    - by Luchaguate
    I have a Windows 7 machine hosting a Windows 7 virtual machine. I am developing a web application using visual studio 2010 on my host machine. I want to run the application in debug mode and access my localhost server from a browser on the virtual machine. (The purpose of this is to be able to debug an application that uses Windows Authentication using different users without having to log off and on for different users on my host machine...) I am using a bridged connection for the virtual machine. I googled how to solve this problem and most of the threads that I found said that if I was using a bridged connection, I could access the server on the host machine by just entering the IP address of my host machine into the url in the browser of the virtual machine. I have tried some different urls using the IP but none of them have worked. As an example, suppose I run my web application in visual studio on my host machine and its url is http://localhost:62789/MyPage.aspx Assume also that I ran ipconfig in CommandPrompt on my host machine and found out that the IP address for my host machine is xxx.xxx.xxx.x. What url should I enter on the virtual machine to access my web application? Thanks in advance.

  • UIAlertView Will not show

    - by John
    I have a program that is requesting a JSON string. I have created a class that contains the connect method below. When the root view is coming up, it does a request to this class and method to load up some data for the root view. When I test the error code (by changing the URL host to 127.0.0.1), I expect the Alert to show. Behavior is that the root view just goes black, and the app aborts with no alert. No errors in debug mode on the console, either. Any thoughts as to this behavior? I've been looking around for hints to this for hours to no avail. Thanks in advance for your help. Note: the conditional for (error) is called, as well as the UIAlertView code. - (NSString *)connect:(NSString *)urlString { NSString *jsonString; UIApplication *app = [UIApplication sharedApplication]; app.networkActivityIndicatorVisible = YES; NSError *error = nil; NSURLResponse *response = nil; NSURL *url = [[NSURL alloc] initWithString:urlString]; NSURLRequest *req = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:10]; NSData *_response = [NSURLConnection sendSynchronousRequest: req returningResponse: &response error: &error]; if (error) { /* inform the user that the connection failed */ //AlertWithMessage(@"Connection Failed!", message); UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Oopsie!" message:@"Unable to connect! Try later, thanks." delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil]; [alert show]; [alert release]; } else { jsonString = [[[NSString alloc] initWithData:_response encoding:NSUTF8StringEncoding] autorelease]; } app.networkActivityIndicatorVisible = NO; [url release]; return jsonString; }

  • How can I specify custom folders for file-browsing in Metro Apps?

    - by klyonrad
    Whenever you use an Metro app and you want to import some files there is a little file browser. Like this: A lot of folders possible; however there is a folder that is very important: The personal Dropbox. How can I add this folder as a "favorite" in this view? Always browsing through the whole filesystem is slow in the Metro Interface. I realize I could make symlinks for all the typical Dropbox folders but that's simply annoying and there has to be another way (just like it's possible to "hack" the "Send To..." options for the context menu.

  • Error in FireFox Loading Images

  • How SSD's drives reduce their latency?

    - by tigrou
    First time i read some information about SSD's, i was surprised to learn they internally use NAND flash chips. This kind of memory is generally slow (low bandwidth) and have high latency while SSD's are just the opposite. But here is how it works : SSD drives increase their bandwidth by using several NAND flash chips in parallel. In other words, they do some data striping (aka RAID0) across several chips (done by the controller). What i don't understand is how SSD's drives managed to reduce latency? (or at least lot better than what a single NAND chip without any controller can do)

  • Changing languages rapidly causes Linux to crash.

    - by eZanmoto
    So I'm running Xmonad on my college computer (which runs Kubuntu) and whenever I leave my desk, instead of using x-screensaver which is incredibly buggy and slow, I just change to another workstation, open a terminal and change language to a language which uses symbols instead of letters, and then change back using an aliased command. For example, my .profile has the lines alias qwer="setxkbmap jp" alias *******="setxkbmap ie" where ******* is my password, using japanese characters. Changing languages seems to be much faster than running x-screensaver. The problem: rapidly changing languages seems to crash Linux; it just won't accept input (and it's not because the language hasn't changed back, nothing is output to the console). I can't use Ctrl+Alt+F1..F7, I can't "raise the elephants", anything, it just won't work. I'm just wondering, is this a known issue, and if so, is there something I can do about it?

  • In need of a Smarter Environmental Package Configuration

    - by Jeremy Liberman
    I am trying to set up a package template in SSIS, following the Wrox Programmer to Programmer book, SQL Server 2008 Integration Services: Problem - Design - Solution. I'm really liking this book even though it is 2008 and we're using SQL Server 2005. I've got a working package template that uses an Indirect XML package configuration to identify what environment (local developer, dev, QA, production, etc) the package is being run in. That locates the SQL Server package configuration for the environment. That set-up is great and all except for the environment variable at the very front of it all. My team would prefer it if the package could use the same environment resource locator as all our other applications and tools use, so we don't two environment markers with essentially the same information in them. Normally we look up a registry key in HKey_Local_Machine but the Registry Package Configuration type only lets you look up the HKey_Current_User registries. My first thought was to write a new Package Configuration Type class that extends the Registry type; after all we'd had such luck writing our own custom log provider. SSIS is super extendable, right? So there doesn't seem to be a way to write your own Package Configuration Types. Is there still some way I can configure my SSIS SQL Server package configuration from a HKLM registry key connection string? If this is not possible, what other workarounds are available? My idea is to write a PowerShell script that will create/modify the Environment Variable that the package will use by fetching the connection string from the registry. This way there's still two markers, but at least then it's automatically maintained and automated. Is this kind of workaround necessary? Thank you for your time.

  • Echoing users by group name in PHP

    - by BobSapp
    What I want to do is click a name of a group(every group what I create other than poweruser and admin groups) and that will echo all of the users in that group from the database. I have figured out the code so far but now my problem is how will I print it all out when clicking the name of the group? My code so far is: <h3>Groups</h3> <?php include('db.php'); if (isset($_GET["groupID"])) { $sql="SELECT `group`.*, `user`.* FROM `user` inner join `group` on group.groupID=user.groupID where group.groupID= " . mysql_real_escape_string($_GET["groupID"]) ; } else { $sql="SELECT * FROM `group` WHERE groupName <> 'admin' AND groupName <> 'poweruser'" ; } $result=mysql_query($sql,$connection); while($line=mysql_fetch_array($result)){ echo "<a href='index.php?page=groups&group=".$line['groupID']."'>".$line['groupName'].'</a><br />'; } mysql_free_result($result); mysql_close($connection); ?>

How can I permanently remove the legal notice. A new laptop is not an option right now.

  • Experience with MooseFS?

    - by brown.2179
    Anyone have any experience using MooseFS? I want an easy distributed storage platform to store static data archive of about 10 TB and serve it to 20-40 nodes. Also I want to be able to add storage as the archive grows without having to rebuild the filesystem. I don't care if it's a bit slow. I just want it to be simple and stable. Basically from what I can see for OS X it's between MooseFS and Gluster. Any other suggestions?
