• How can I install my installed linux on another hardware too?

  - by donamir

  Hi. It's my state: I installed some apps on a linux server(ubuntu). Apps stack are development tools: -some of Atlassian product -SVN, USVN -Maven, Artifactory -Tomcat & ... My problem: I want to create a bootable dvd to be able to restore same state(OS, configuration and apps) on another hardware(server). Some notes: I prefer ubuntu but my linux can be a different distributions if needed. w I prefer final result (bootable dvd) be simple and easy to use as installing a linux(ubuntu). I prefer a bootable DVD but if it's not possible, any other solution like partial backup/package even if needed to install first OS and then apply the package/backup/... can be good. Finally: Thanks in advance.

• How to go about scheduling a task in windows 7 to change wireless connection

  - by Skindeep2366

  This may or not be something that can be done. I cannot find anything on the wireless connection manager built into windows 7 let alone methods for passing params into it. Problem is as follows: I have 2 wireless routers. One provides internet access, the other provides sole access to the local network. Every day at 4am the main system creates a backup in 2 locations. One is a External usb drive, the other is a location on the network. This is all cool if it is remembered to change over to the local network router before leaving. But if it is forgotten the roof will collapse, the walls will burn, and I will be... well you get the idea. Solution: there is already a custom event that fires a automated backup program at 4am everyday. I need someway to force the wireless network to use the correct connection at say 3:58am everyday. Any ideas????

• Ubuntu 12.04.3 64 bit with Nemo 2.0.x no thumbnails

  - by Dr. Szrapnel

  I have strange problem with thumbnails in my Ubuntu machine. I was using Ubuntu with Cinnamon 1.8 from stable ppa and it was good but then Cinnamon 2.0 came out with some broken packages uploaded to stable ppa nad things gone wrong... Anyway after few updates Cinnamon started to work normaly except Nemo - there are no thumbnails at all, only icons. I heve tried purging /.cache/thumbnails and .thumbnails folders but this doesn't work. Next I have changed permissions for those folders - that didn't helped either. Then I've set Nemo as default file manager and desktop handler but with no result. What is weird - when I start Nautilus and open some folder with images then close it and open same folder with Nemo thumbnails appears but when I clean thumbnails directories there are no thumbnails again. It would be great if someone have some solution for this annoying Nemo behavior because I really don't want to resign from Cinnamon. p.s. I have set preview options in Nemo for Always and no bigger files than 4GB so that is not the case.

• How to mount remote samba share from local host with multiple groups?

  - by Dragos

  I am using mount.cifs to mount a remote samba share (both client and server are Ubuntu server 8.04) like this: mount.cifs //sambaserver/samba /mountpath -o credentials=/path/.credentials,uid=someuser,gid=1000 $ cat .credentials username=user password=password I mounted a user from local system with username and password with mount.cifs but the problem is that the user is part of multiple groups on the remote system and with mount.cifs I can only specify one gid. Is there a way to specify all the gids that the remote user has? Is there a way to: Mount the remote samba with multiple groups on the local system? Browse the mount from 1) with the terminal since I want to pass some files from samba as arguments to local programs. Other solutions would be: nautilus sftp:// which runs through gvfs; but the newer gnome does not write to disk the ~/.gvfs anymore so I can't browse it in terminal. And the last solution would be NFS but that means that I have to synchronize the uids and gids on the local system with the ones from the server.

• OS X Snow Leopard, change file permissions on copy

  - by Francesco K

  I work with OS X, Snow Leopard and need to allow users to make copies of files (templates) located in a read-only repository for subsequent editing. The repository is located on a separate physical drive mounted to the OS X boot volume. As this is a shared computer in a school environment, all users access the machine via a single login ("user_local"). Whether using POSIX permissions or ACLs, the use case requires the file permissions to change from "read" to "read write" as they get copied to the "user_local" home directory. Googling around has not yielded anything that would indicate that this is possible via the Snow Leopard permission system. Question 1: Is this in fact possible via the permission system? If so, how? Question 2: If not possible, how would one go about solving this problem? I imagine this to be a fairly common use case so there must be a workable solution for it out there. Thanks.

• What are some good methods to improve personal password management?

  - by danilo

  I want to improve my personal password management. I usually use secure passwords, but overuse them for too many different places. My questions: What methods do you use to create passwords, e.g. for different online sites/logins? What methods do you use to remember those passwords? Memory? Pen&Paper? Software storage? Is there some good way to store my passwords somewhere, so I can always have access to them when I need them (e.g. a webbased solution on my own server) but at the same way keep them away from unwanted access? Edit: Someone on another site mentioned http://passwordmaker.org/. Have you had any good or bad experiences with that software?

• Overwrite text in Windows Notepad

  - by Mark Miller

  I would like to be able to overwrite text in Windows Notepad. I am using Windows 7 Professional. Ideally I would like to be able to position the cursor next to a string of text and erase that text by pressing the spacebar until the cursor has passed over every character in the string without adding additional spaces to the document. Is that possible? I have tried pressing the 'Insert' key, but that does not help. Nor does using 'Num Lock' and pressing the 'Ins' or '0' key. Unfortunately, I have not been able to find a solution elsewhere on the internet. I do not think I am using notepad++. The application is listed as 'notepad.exe' under 'Properties'. Thank you for any suggestions.

  - by jab

  I've got a computer running Windows 2003 R2 Standard Edition Service Pack 2 and periodically (every 5 minutes) the systems generates 2 errors that can be seen in the event viewer. The codes of the events are 1030, 1006 that seems to be related to group policies... I don´t know if these events are realted to the perfomance of the system but anyway i would like to fix them. I've googled around and seems to be a common problem but i haven't found a solution for these events. Do you know how can be fix it? Thanks in advance

• faking NAT with a VMware distributed switch across multiple hosts

  - by romant

  I need to construct a NAT for certain machines within the network. Wish to do this with dvSwitch - as it seems the logical way of attacking the problem as in this scenario there's just under 30 hosts. In order for the NAT'ed VM's to have access to the 'real' network. I am providing a 'router' VM, which will have access to the WAN/outside network, and also act as the DHCP server for the NAT'ed machines. Problem Space When the machines connected to the NAT interface and the router are on the same host, then they get an IP from the router VM, and work perfectly (routed outside). Unfortunately machines on other Hosts that are connected to the dvSwitch do not get an IP and further tcpdump shows no network data getting through across the hosts within the dvSwitch. Has anyone achieved a NAT solution using a dvSwitch before that they could share?! Thank you. EDIT: Including the diagram.

• How to pass an argument to a Windows Scheduled Task with spaces in it

  - by Rodney

  I need to set up a Windows Scheduled Task. It accepts 1 parameter/argument which is a path and can contain spaces. My Scheduled task does not work - it "breaks" the parameter up at the first space. If I run it in the Command Prompt I can just wrap the argument in " " and it works fine, however, this does not work in the Scheduled Task UI. e.g. C:\Program Files\xyz\FTP File Transfer\FTPFileTransferTask.exe "C:\Program Files\xyz\The Interface\Folder Path" I have tried wrapping the argument with " " ' ' [ ] () and have tried filling in the spaces with %20, ~1 etc. with no luck. I know of one solution to make a bat file and use " " around my argument but I don't want to add more complexity. I tried it on Windows 7 and Windows 2008 Server and both failed. There seems to be no discussions on this?

• How to loop section from a song correctly?

  - by Teflo

  I'm programming a little Music Engine for my game in C# and XNA, and one aspect from it is the possibility to loop a section from a song. For example, my song has an intropart, and when the song reached the end ( or any other specific point ), it jumps back where the intropart is just over. ( A - B - B - B ... ) Now I'm using IrrKlank, which is working perfectly, without any gaps, but I have a problem: The point where to jump back is a bit inaccurate. Here's some example code: public bool Passed(float time) { if ( PlayPosition >= time ) return true; return false; } //somewhere else if( song.Passed( 10.0f ) ) song.JumpTo( 5.0f ); Now the problem is, the song passes the 10 seconds, but play a few milliseconds until 10.1f or so, and then jumps to 5 seconds. It's not that dramatic, but very incorrect for my needs. I tried to fix it like that: public bool Passed( float time ) { if( PlayPosition + 3 * dt >= time && PlayPosition <= time ) return true; return false; } ( dt is the delta time, the elapsed time since the last frame ) But I don't think, that's a good solution for that. I hope, you can understand my problem ( and my english, yay /o/ ) and help me :)

• how to find the clientname of an remote desktop session?

  - by Hemal Pandya

  We have servers on which we run tests and all users connect using the same credentials. The server allows 2 connections. What happens often is that one user is already active and the other two users keep hijacking the remaining session. Using query session, I can find out what are the active connections. But it does not list the client machine from where the session originates, which taskmanager displays. How do I get this information from a remote machine? I prefer a command line solution. Thanks in advance.

• How to remove the smell of cigarette from the computer?

  - by Tio

  So I'm a smoker, and of course I smoke in front of the computer when I'm at home. On last Friday I moved out from my mothers house to my own, and since the computers were always turned on and the room was a room that everybody could smoke, the smell didn't bother me. At my new home, I turned them on, about 15 minutes ago, and I'm dying because of the smell of cigarette ( this may be kind of stupid from a smoker, but I hope some of you understand ). This solution has to be relatively quick, because I can't stay without the desktop and the server for one week, for example. Tomorrow, I'm going to open them both, and remove all dust there is inside, this should clear some of the smell, but probably won't remove it completely. Does anyone know a technique to get rid of the smell?

• Securing RDP access to Windows Server 2008 R2: is Network Level Authentication enough?

  - by jamesfm

  I am a dev with little admin expertise, administering a single dedicated web server remotely. A recent independent security audit of our site recommended that "RDP is not exposed to the Internet and that a robust management solution such as a VPN is considered for remote access. When used, RDP should be configured for Server Authentication to ensure that clients cannot be subjected to man-in-the-middle attacks." Having read around a bit, it seems like Network Level Authentication is a Good Thing so I have enabled the "Allow connections only from Remote Desktop with NLA" option on the server today. Is this acion enough to mitigate the risk of a Man-in-the-Middle attack? Or are there other essential steps I should be taking? If VPN is essential, how do I go about it?

• disable 250 character URL limit in Internet Explorer

  - by Keltari

  Users of a SharePoint Document Library are getting this error: The URL for this file is too long for the application. A temporary copy of this file will be opened on your computer. You must save this copy as a new file. After doing some research, it appears Internet Explorer has a limit of about ~250 characters for a URL. Some URLs provided by SharePoint far exceed this limit. One example being 790 characters long. Is there a way to disable this limit? I have looked, but there doesnt appear to be a solution, other than shortening the folder/path names.

• Best way to implement mouse-based movement in MMOG

  - by fiftyeight

  I want to design an MMO where players click the destination they want to walk to with their mouse and the character moves there, similar to Runescape in this manner. I think it should be easier than keyboard movement since the client can simply send the server the destination each time the player clicks on a destination. The main thing I'm trying to decide is what to do when there are obstacles in the way. It's no problem to implement a simple path-finding solution on the client, the question is if the server will do path-finding as well, since it'll probably take too much Computation power from the server. What I though is that when there is an obstacle the client will send only the first coordinate it plans to go to and then when he gets there he'll send the next coordinate automatically. For example if there is a rock in the way the character will decide on a route that is made of two destinations so it goes around the rock and when it arrives at the first destination it sends the next coordinate. That way if the player changes destination is the middle he won't send unnecessary information. Is this a good way to implement it and is there a standard way MMOGs usually do it? EDIT: I should also mention that the server will make sure all movements are legal and there aren't any walls in the way etc. In the way I wrote it should be quite easy since all movements will be sent in straight lines so the server will just check there aren't any obstacles along that line.

• BizTalk 2009 - Scoped Record Counting in Maps

  - by StuartBrierley

  Within BizTalk there is a functoid called Record Count that will return the number of instances of a repeated record or repeated element that occur in a message instance. The input to this functoid is the record or element to be counted. As an example take the following Source schema, where the Source message has a repeated record called Box and each Box has a repeated element called Item: An instance of this Source schema may look as follows; 2 box records - one with 2 items and one with only 1 item. Our destination schema has a number of elements and a repeated box record.  The top level elements contain totals for the number of boxes and the overall number of items.  Each box record contains a single element representing the number of items in that box. Using the Record Count functoid it is easy to map the top level elements, producing the expected totals of 2 boxes and 3 items: We now need to map the total number of items per box, but how will we do this?  We have already seen that the record count functoid returns the total number of instances for the entire message, and unfortunately it does not allow you to specify a scoping parameter.  In order to acheive Scoped Record Counting we will need to make use of a combination of functoids. As you can see above, by linking to a Logical Existence functoid from the record/element to be counted we can then feed the output into a Value Mapping functoid.  Set the other Value Mapping parameter to "1" and link the output to a Cumulative Sum functoid. Set the other Cumulative Sum functoid parameter to "1" to limit the scope of the Cumulative Sum. This gives us the expected results of Items per Box of 2 and 1 respectively. I ran into this issue with a larger schema on a more complex map, but the eventual solution is still the same.  Hopefully this simplified example will act as a good reminder to me and save someone out there a few minutes of brain scratching.

• Team Foundation Service Preview now open for all!

  - by Tarun Arora

  The concept of TFS in the cloud was first presented back in early 2010, the product team worked hard to preview a constantly evolving solution at the BUILD conference last year and after having completed 31 Sprints today the preview service has been opened for all. No more invitation codes required, TfsPreview has been made public! “Since we announced the Team Foundation Service Preview at the BUILD conference last year, we’ve limited the on boarding of new customers by requiring invitation codes to create accounts.  The main reason for this has been to control the growth of the service to make sure it didn’t run away from us and end up with a bad user experience.  In this time period, we’ve continued to work on our infrastructure, performance, scale, monitoring, management and, of course, some cool new features like cloud build. ”   - Brian Harry Since the service is still in preview, it is free for all… If you haven’t, now is the best time to try out the offering. There is no fixed time line on how long before service becomes chargeable but the terms of service support production use, the service is reliable and the product team committed to carry all of your data forward into production. “The service will remain in “preview” for a while longer while we work through additional features like data portability, commercial terms, etc but the terms of service support production use, the service is reliable and we expect to carry all of your data forward into production. ”  - Brian Harry As of today it’s possible to use TFS Preview with VS 2012 RC, VS 2010 SP1, VS 2008 SP1, the service currently does not work with VS 2005, this is something the product team is actively working on. You can refer to Brian’s announcement blog post here, http://blogs.msdn.com/b/bharry/archive/2012/06/11/team-foundation-service-preview-is-public.aspx

• Compute the AES-encryption key given the plaintext and its ciphertext?

  - by Null Pointers etc.

  I'm tasked with creating database tables in Oracle which contain encrypted strings (i.e., the columns are RAW). The strings are encrypted by the application (using AES, 128-bit key) and stored in Oracle, then later retrieved from Oracle and decrypted (i.e., Oracle itself never sees the unencrypted strings). I've come across this one column that will be one of two strings. I'm worried that someone will notice and presumably figure out what those two values to figure out the AES key. For example, if someone sees that the column is either Ciphertext #1 or #2: Ciphertext #1: BF,4F,8B,FE, 60,D8,33,56, 1B,F2,35,72, 49,20,DE,C6. Ciphertext #2: BC,E8,54,BD, F4,B3,36,3B, DD,70,76,45, 29,28,50,07. and knows the corresponding Plaintexts: Plaintext #1 ("Detroit"): 44,00,65,00, 74,00,72,00, 6F,00,69,00, 74,00,00,00. Plaintext #2 ("Chicago"): 43,00,68,00, 69,00,63,00, 61,00,67,00, 6F,00,00,00. can he deduce that the encryption key is "Buffalo"? 42,00,75,00, 66,00,66,00, 61,00,6C,00, 6F,00,00,00. I'm thinking that there should be only one 128-bit key that could convert Plaintext #1 to Ciphertext #1. Does this mean I should go to a 192-bit or 256-bit key instead, or find some other solution? (As an aside, here are two other ciphertexts for the same plaintexts but with a different key.) Ciphertext #1 A ("Detroit"): E4,28,29,E3, 6E,C2,64,FA, A1,F4,F4,96, FC,18,4A,C5. Ciphertext #2 A ("Chicago"): EA,87,30,F0, AC,44,5D,ED, FD,EB,A8,79, 83,59,53,B7.

• What benefits can I get upgrading my ASP.NET (Webform) + DAL(EF) + Repository + BLL structure to MVC?

  - by Etienne

  I'm in the process of defining an approach that may best fit our needs for a big web application development. For now, I'm thinking going with an ASP.NET Architecture with a DAL using Entity Framework, a Repository concept to not access DAL directly from BLL and a BLL that call the repository and make every manipulations necessary to prepare data to push in a presentation layer (.aspx files). I don't plan to use ASP.Net controls and prefer to keep things simple and lightweight using plain html, jQuery UI controls and do most of the server calls with jQuery Ajax. Sometimes, when needed, I plan to use handlers (.ashx) to call BLL methods that will return JSON or HTML to client for dynamic stuff. My solution also has a test project that Mock the Repository with in-memory data to not repose on database for testing BLL methods... It may be usefull to add that we will build a big application over this architecture with hundreds of tables and store procedures with a lot of reading and writing to database. My question is, having this architecture in mind, Is there any evident advantages that I can obtain by using an MVC3 project instead of the described architecture base on Webform? Do you see any problem in this architecture that may cause us problem during the next steps of development? I know the MVC pattern for using it in others projects with Django... but the Microsoft MVC implementation look so much more complex and verbose than Django MVC and it's why I'm hesitating (or waiting for a little push?) right now before jumping into it... We are in a real project with deadlines and don't want to slow the development process without any real benefits.

• How to mange big amount users at server side?

  - by Rami

  I built a social android application in which users can see other users around them by gps location. at the beginning thing went well as i had low number of users, But now that I have increasing number of users (about 1500 +100 every day) I revealed a major problem in my design. In my Google App Engine servlet I have static HashMap that holding all the users profiles objects, currenty 1500 and this number will increase as more users register. Why I'm doing it Every user that requesting for the users around him compares his gps with other users and check if they are in his 10km radius, this happens every 5 min on average. That is why I can't get the users from db every time because GAE read/write operation quota will tare me apart. The problem with this desgin is As the number of users increased the Hashmap turns to null every 4-6 hours, I thing that this time is getting shorten but I'm not sure. I'm fixing this by reloading the users from the db every time I detect that it became null, But this causes DOS to my users for 30 sec, So I'm looking for better solution. I'm guessing that it happens because the size of the hashmap, Am I right? I have been advised to use spatial database, but that mean that I can't work with GAE any more and that mean that I need to build my big server all over again and lose my existing DB. Is there something I can do with the existing tools? Thanks.

• Samsung i780 networking problem

  Hello guys! Maybe this is not the right place to ask this, but I give a try for it. Please don't rate it down, just ignore it if you don't like. So I have a Samsung i780 mobile phone and I would like to use the internet through my wireless router. I have connected to it. I got an IP address. My laptop is also connected to the same wireless network and I can ping the mobile phone and I get answer. When I open the internet explorer and enter an address it says that it cannot connect to the internet. I have googled very much, but can't find the problem. What do you think, what is the solution?

• basic device that can connect to internet

  - by Hellnar

  Hello, I am looking for a cheap solution to my problem: I need to find either an already existing common device (that is used in restaurants, bars clubs) or a cheap new device that I will distribute to those places, which can connect to internet (via the already existing ethernet or wireless based internet) and do HTTP request/receive response and retrieve information ? (For instance can a POS device connect to internet?) For a project, I need to do identity validation on several restaurants and bars and not all of them have computers. So I will be giving "cheap and easy to use devices" and non-IT personal can use it to do http request to my server and get response. All I can think of is Cell phones and SMS.
