• How to specify what network interface to use with TTCP or IPERF?

  - by Sammy

  The PC has two Gigabit Ethernet ports. They function as two separate network adapters. I'm trying to do a simple loopback test between the two. I've tried TTCP and IPERF. They're giving me hard time because I'm using the same physical PC. Using pcattcp...

But why does it say 0.0.0.0? Is it passing through only one of the network adapters? I want 10.1.1.1 to be the server (receiver) and 10.1.1.2 to be the client (transmitter). These are the IP addresses assigned manually to each network adapter. How do I specify these addresses in TTCP? There is also the IPERF tool which has the -B option. Unfortunately I've been only able to use this option to bind the server to the 10.1.1.1 address. I was unable to bind the client to the 10.1.1.2 address. I might be doing it wrong. Can the -B option be used for both the server as well as the client side? What does the syntax look like for the client?

• External hard drive becomes unwriteable after awhile

  - by Brandon

  I have an external USB hard drive mounted in Ubuntu 9.10 with full read/write abilities over SMB. If it stays on for awhile though, I lose the ability to write to it. I end up having to ssh in and unmount, mount, reboot in order to have write ability again. Any reason on what might be causing this and how to fix it?

• Generating Google Maps markers using Ruby

  - by ischnura

  I would like to do a very simple task: add some markers in a Google Map using a list of addresses from an array. I have been thinking about generating the Google Maps JavaScript API code using ruby (printf) but this does not seem like a very clean and beautiful solution... I have read about YM4R for Ruby on Rails... my project is pretty simple and I have never worked with Ruby on Rails... I have also never used JQuerry... but I am very willing to learn to use this tools :) What do you think will be the best approach to generating the markers?

• How can I prevent tmux exiting with Ctrl-d?

  - by Cas

  I use tmux on my server and recently I found to my cost that ctrl-d will exit tmux and lose all the session information, my intention was to simply end the ssh session but failed to notice I was still in tmux until too late. I am aware that I should be careful in future when using ctrl-d but I wondered if there a way to prevent tmux for exiting when hitting ctrl-d by accident? A solution such as a prompt, confirmation or detaching would be fine.

• Javascript onbeforeunload Issue

  - by Nik

  Alright, I have an issue with the following code. What happens is when a user closes their browser, it should prompt them to either click OK or click CANCEL to leave the page. Clicking OK would trigger a window.location to redirect to another page for user tracking (and yes, to avoid flame wars, there is a secondary system in place to assure accurate tracking, in the event of the user killing the browser from the task manager (as mentioned in similar questions)). CANCEL would remain on the page, the issue being that no matter what button you hit, you get redirected as if you wanted to leave the page. The relevant code is below. window.onbeforeunload = confirmExit; function confirmExit() { var where_to = confirm("Click OK to exit, Click CANCEL to stay."); if (where_to == true) { window.location="logout.php"; } if (where_to == false){ alert("Returning..."); } }

• iphone: the executable was signed with invalid entitlements

  - by numbernine

  I'm trying to install my iphone app on my device for testing and whenever I try to build it I get: The executable was signed with invalid entitlements The entitlements specificed in your application's Code Signing Entitlements do not match those specified in your provisioning profile. Now I've tried adding an Entitlements.plist file and both checking and unchecking get-task-allow. I've added the file name under Code Signing Entitlements under the project and then under the target, both, neither, etc. I've deleted and re-created every app id, provisioning profile, and certificate. Those all seem valid. This is not an ad-hoc distribution (it's development) and it's not a jailbroken phone. I don't even understand where in the provisioning profile any Code Signing Entitlements are specified..?

• What is "Virtual Size" in sysinternals process explorer

  - by robert

  Hi My application runs for few hours, There is no increase in any value ( vmsize, memory) of Task Manager. But after few hours i get out of memory errors. In sysinternals i see that "Virtual Size" is contineously increasing, and when it reach around 2 GB i start getting memory errors. So what kind of memory leak is that ? How can i demonstrate it with a code ? Is it possible to reproduce same thing with any piece of code where none of the memory value increase but only the Virtual Size in sysinternsl process explorer increase ? thanks for any suggestions

• Can't manage iPod from linux anymore

  - by kemp

  I used to be able to see and manage my iPod with different softwares: Amarok, Rhythmbox, GTKPod. The device is a nano 1st generation 4gb. Currently it mounts regularly and can be accessed from the file system, but I get this in dmesg: [ 1547.617891] scsi 11:0:0:0: Direct-Access Apple iPod 1.62 PQ: 0 ANSI: 0 [ 1547.619103] sd 11:0:0:0: Attached scsi generic sg2 type 0 [ 1547.620478] sd 11:0:0:0: [sdb] Adjusting the sector count from its reported value: 7999488 [ 1547.620494] sd 11:0:0:0: [sdb] 7999487 512-byte hardware sectors: (4.09 GB/3.81 GiB) [ 1547.621718] sd 11:0:0:0: [sdb] Write Protect is off [ 1547.621726] sd 11:0:0:0: [sdb] Mode Sense: 68 00 00 08 [ 1547.621732] sd 11:0:0:0: [sdb] Assuming drive cache: write through [ 1547.623591] sd 11:0:0:0: [sdb] Adjusting the sector count from its reported value: 7999488 [ 1547.624993] sd 11:0:0:0: [sdb] Assuming drive cache: write through [ 1547.625003] sdb: sdb1 sdb2 [ 1547.629686] sd 11:0:0:0: [sdb] Attached SCSI removable disk [ 1548.084026] FAT: utf8 is not a recommended IO charset for FAT filesystems, filesystem will be case sensitive!

I say partially because I can transfer files to the iPod but can't remove or modify them. Also one transfer didn't finish and only 9 out of 16 songs were delivered to the device. All other softwares I tried (GTKPod, Amarok, Songbird) don't even detect it. What can I do to troubleshoot this?

Haven't been using my iPod for a while so I can't say when exactly it stopped working. I'm sure Amarok was still at version 1.X but can't remember when it was. My current system is debian testing fully updated. NOTE: just noticed that if I mount the device manually instead of letting nautilus automount it, I can see it again on GTKPod but still not on Banshee AND it's vanished from Rhythmbox...

• project hours worked to be sum of tasks hours worked.

  - by silverkid

  i have a sharepoint list called project . this list has column called hours worked. Then i also have a list called tasks. this list also has a column called hours worked. the task list also has a lookup field where we select project ID from project list. Thus for each project we can have many tasks. now tasks list items are created by individual users and i have to create such a mechanism that the hours worked in project list must always be the sum of hours worked in tasks of that project. How can I achieve this.

• Laserjet Experts: How many power cycles per month?

  - by marienbad

  I recently got a nice Laserjet 8100DN for my house. I will probably never print more than 1% of its rated monthly duty cycle. But it runs some fairly noisy fans 24/7 if it's left on, so I am in the habit of turning the machine off as soon as I'm done with it. So, for all you who have a lot of experiencing administrating workgroup LaserJets, do you think I'll end up killing it from too many on-off cycles?

• AnkhSVN: moving a project to another repo

  - by pcampbell

  My task is to move this VS solution and projects to another SVN server. I'm working with Visual Studio 2010 RC1 and AnkhSVN 2.1.7819.... Currently the files are all bound to a repo at C:\Repositories\foo. I'd like to move it to http://someSite/svn/foo I'm presented with this error message: Repository UUID '152c39db-5799-4234-85f2-074004a6fcad' doesn't match expected UUID '6c83444d-7f93-d64a-b0a0-23283495cf17' Questions How can I avoid this message in AnkhSVN? Are there better solutions for moving the source into a repo on the new target? How can I get Ankh to 'forget' that repo at C:\Repositories\ forever?

• Web framework for an application utilizing existing database?

  - by tputkonen

  A legacy web application written using PHP and utilizing MySql database needs to be rewritten completely. However, the existing database structure must not be changed at all. I'm looking for suggestions on which framework would be most suitable for this task? Language candidates are Python, PHP, Ruby and Java. According to many sources it might be challenging to utilize rails effectively with existing database. Also I have not found a way to automatically generate models out of the database. With Django it's very easy to generate models automatically. However I'd appreciate first hand experience on its suitability to work with legacy DBs. Also I appreciate suggestions of other frameworks worth considering.

• Is there a Linux equivalent of Yousendit?

  - by user39234

  We want to get functionality similar to Yousendit or one of the other services that allows end users to upload large files. But we have a few Linux servers and want to use these instead of a third parties. There seems to be software for practically everything else for Linux, I can't believe there isn't something that will meet our needs.

• Large file upload into WSS v3

  - by Rubens Farias

  I'd built an WSSv3 application which upload files in small chunks; when every data piece arrives, I temporarly keep it into a SQL 2005 image data type field for performance reasons**. Problem come when upload ends; I need to move data from my SQL Server to Sharepoint Document Library through WSSv3 object model. Right now, I can think two approaches: SPFileCollection.Add(string, (byte[])reader[0]); // OutOfMemoryException and SPFile file = folder.Files.Add("filename", new byte[]{ }); using(Stream stream = file.OpenBinaryStream()) { // ... init vars and stuff ... while ((bytes = reader.GetBytes(0, offset, buffer, 0, BUFFER_SIZE)) 0) { stream.Write(buffer, 0, (int)bytes); // Timeout issues } file.SaveBinary(stream); } Are there any other way to complete successfully this task? ** Performance reasons: if you tries to write every chunk directly at Sharepoint, you'll note a performance degradation as file grows up (100Mb).

• SharePoint 2007 Central Admin w3wp.exe process consumin 99% CPU

  - by Matrich

  Hi, I have been running an intranet using SharePoint 2007 for over a year and all has been working fine. However, after some time, I realized that the intranet portal was slow. Trying to access the Central Admin over another computer not the SharePoint server also became an issue. So I logged onto the real SharePoint Server and it took some ages to login and then was so slow even on the server unlike other times. When I checked the Task Manager, I found out that w3wp.exe was consuming 99% of the CPU speed. When I restarted the Central Admin App Pool, everything came back to normal and all was running well but after a few minutes (15 or so), it again became slow. I have checked the Event Logs and nothing conclusive was there to help me out. Anyone who has had this experience? or has any good resource? Please help. Thanks in advance

• Core Location Best Placement and User Interruption

  - by b.dot

  Hi All, My application uses Core Location in three different views. It's working perfectly. In my first view, I subclass the CLLocationManager and use protocol methods for location updates to my calling class. Before I install the framework and code in my other classes, I was wondering: Is the protocol method the best way? What happens to the Core Location execution if the user exits the view or quits the app while it's trying to get a location fix? Is the location task terminated with the GPS system turned off immediately? If the user simply switches to another view, is it OK to assume that I can start Core Location in the next view without regard to the last? Where should the first update location call be placed. Should the application delegate instantiate the CLLocation Manager class using protocol so that it can update any of the views chosen or should each class instantiate the manager. Any feedback would be appreciated. Thanks.

• Prototyping Object in Javascript breaks jQuery?

  - by blesh

  I have added a simple .js to my page that has some pretty mundane common-task sort of functions added to the Object and Array prototypes. Through trial and error I've figured out that adding any function to Object.prototype, no matter it's name or what it does causes javascript errors in jQuery: The culprit? Object.prototype.foo = function() { /*do nothing and break jQuery*/ }; The error I'm getting line 1056 of jquery-1.3.2.js, in the attr:function { } declaration: /*Object doesn't support this property or method*/ name = name.replace(/-([a-z])/ig, function(all, letter) { return letter.toUpperCase(); }); Apparently G.replace is undefined. While it's obvious that there's something I'm just not wrapping my head around with prototyping, I'm failing miserably to figure out what it is. To be clear, I'm not looking for a workaround, I have that handled... what I'm looking for is an answer to 'Why?'. Why does adding a function to Object.prototype break this bit of code?

• Determining the hostname/IP address from the MX record in PHP

  - by pmmenneg

  Hi there, have a basic email domain validation script that takes a user's email domain, resolves the IP address from that and then checks that against various published blacklists. Here is how I am determining the IP: $domain = substr(strchr($email, '@'), 1); $ip = gethostbyname($domain); The problem is that some email address domains, such as [email protected], use an MX record rather than an A record, so using gethostbyname('alumni.example.net') will fail to resolve. I know when a user's email is using an MX in the email itself by using the PHP checkdnsrr function, but once at that stage am a little stuck as to how to proceed. In theory, I could parse out the 'root' domain, i.e. 'example.net' and check it, but I've not found reliable regex that can handle this task when the user could easily have an email the format of [email protected]... So, any suggestions on how to best tackle this??

  I'm doing an end-of-the-year clean up and found some old OS install media - Mac OS X 10.3.5, Windows 2000, Windows XP. It seems wrong to just throw them out but they can't have a home with me anymore.  Is there some place I can donate them to?  Anyone know of anyone collecting this stuff for posterity?

• TFS and SVN code Merge

  - by Mohanavel

  We are a small team of 8. 3 are from other country and they are using the Source controller as TFS and TFS server is also located there and they have only 4 licence. So we (5 developers) are using SVN source controller as local source controller and for every 3 days we are taking the TFS latest and merging the changes from and to SVN & TFS. Really this is overkilling and hour consuming task. They don't want to change the TFS ( Not event add ins ). So what i can use to merge the code between two source controllers. Is it i can use SVN-Bridge to Merge the code without changing or modifying the TFS Server. Please guide me on this. (Worst case they might go for add ins, for sure no other source controllers than Microsoft Product) hhhmmmmmm, i'm sitting in front of monitor and hitting the F5 on this page, Please save my hours.

• Sending email from various domains

So, today we send it from our domain: example.com However, we would like to send email to come from their specific domains. When we put their customer emails in Reply-To - it shows up as "on behalf" in clients like outlook. What are the ways to send email from their domain without installing software on their network?
