• AutoMatically Creating New Sites When New Users Sign Up

  - by Eddy Freeman

  I would like to know how hosted eCommerce sites like www.shopify.com, www.3dCart.com etc.. automatically creates new sites when new users sign up. What kind of tools do they use to create those sites into the users profile. I have tried googling but couldn't find an answer. Does any of you guys have any knowledge or experience that you can share with me? Or do you know a tutorial that you can point me to? I hope my question is clear. Thanks for your help.

• starting up with VPS or cloud hosting? [closed]

  - by FlyOn

  Possible Duplicate: How to find web hosting that meets my requirements? Summary: I want to start hosting my product. I'd like to register domains (at some point). I'm a linux beginner. Thinking about scalability and price, I'm thinking am I better off on a VPN to get started or would some form of cloud hosting be better (not being familiar with either). Full question: I'm creating a product where people can create their own 3D representations of whatever data / info they have, and (re)organise that data. The product is coming along beautifully on my local environment, but it's about time I start getting some form of hosting ready, and I could really use some advice where / how to get started: I'd like people to be able to move/register their own domains on my server. I could start without this just to demo the product, but it would be the very first on the todo list. I'd like to automatically copy some files / install databases etc for each domain. I probably want to see if I can let users manage their own subdomains at some points, but for now: I'd like start as simple as possible. I've always on a windows machine, so my linux experience is quite basic. I really don't mind getting into it, but I'm thinking it's better to get my product out first of all and see where to go from there. Although... I'd like things to be scalable. If I set up some reseller VPN now which only scales to 100 domains or so, which means I have to set up something else / move again when I pass that level, or which means that I'm in trouble if I suddenly get lots of new customers... hmm. Finally, I need to start cheap. I'm putting all I have into starting this company, and live on very little. So before I have any customers, 50 dollars a month is a fair bit and 100 dollars a month may be too much. If anyone has some tips to help get me started I'd be really grateful.

• Friday Tips #6, Part 2

  - by Chris Kawalek

  Here is a question about updating Oracle VM: Question: How can I perform Oracle VM 3 server updates from Oracle VM Manager? Answer by Gregory King, Principal Best Practices Consultant, Oracle VM Product Management: Server Update Manager is a built-in feature of the Oracle VM Manager. Basically, Server Update Manager automatically configures YUM updates on all the Oracle VM Servers, pointing each to our Unbreakable Linux Network (ULN) update channel for Oracle VM. The servers periodically check with our Oracle YUM repository and notify the Oracle VM Manager that an update is available for each server. Actual server updates must be triggered by the Oracle VM administrator – they are not executed automatically. At this point, you can use the Oracle VM Manager to put a server into maintenance mode which live migrates all the running Oracle VM Guests to other Oracle VM Servers in the server pool. Once all the Oracle VM Guests have been migrated, the Oracle VM administrator can trigger the update on the server. The entire process is documented in the Installation and Upgrade Guide of Oracle VM Documentation so I won’t spend time detailing the steps. However, configuring the Server Update Manager is exceedingly simple. Simply navigate to the Tools and Resources tab in the Oracle VM Manager, select the link for Server Update Manager and ensure the following values are added to the text boxes as shown in the illustration below: YUM Base URL: http://public-yum.oracle.com/repo/OracleVM/OVM3/latest/x86_64 YUM GPG Key: file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle Every server in the pool will be automatically configured for YUM updates once you choose the Apply button. Many thanks to Greg and Rick for providing the answers to this week's questions. If you want to ask us something, hit up Twitter and use hashtag #AskOracleVirtualization. See you next week! -Chris

• Problem with creating table on phpMyAdmin database

  - by tombull89

  Hello all, I'm running a phpMyAdmin Database on my web package on a 1and1-hosted server. I've managed to set up a database in the control panel, have uploaded all to root/phpmyadmin and changed the config.ini.php file to point at 1and1's database server (because that's the way they do it). I can go to the web interface and get to the main page, but all it shows is the database name and I can't find how to create any tables. I know it's a long shot but I'm almost out of ideas. Also, 1and1 have their own phpmyadmin panel, which is pretty annoying to use, and a 1and1 webdatabase which I have barely looked at. Help and suggestions much appriciated.

• Mapping an sFTP connection to a Windows drive?

  - by Nicolas

  I'm looking for a way to map an sFTP connection to a Windows (Vista) drive. In other words, a tool that would add a new drive (let's say N:) to my computer, that would directly point to my remote server via sFTP. That way, "N:\my_dir\file.txt" would actually be something like "/home/user/my_dir/file.txt" on the remote server. Reading the file on Windows would download it, and writing content in it would upload it...network transfers being made via sFTP. I'm aware of Novell NetDrive, but it has various issues with long filenames, and seems to corrupt UTF-8 files content depending on the BOM. Do you know about any reliable alternative ? Thanks ! Edit : I have complete control of the remote server, except that it's remote enough for me not to be able to physically access it.

• Redmine Subversion: LDAP _and_ local auth

  - by Frank Brenner

  I need to set up a subversion repository with apache authentication against both an external LDAP server as well as the local Redmine database. That is, we have users whose accounts exist only in the LDAP directory and some users whose accounts only exist in the local Redmine db - all should be able to access the repo. I can't quite seem to get the apache config right for this. I know I saw a how-to for this at some point, I think using Redmine.pm, but I can't seem to find it anymore.. Thanks.

• to measure throughput of testing device connect to server via AP

  - by samantha

  Description of project- I have a test tool to which DUT connects. The test tool has an access point in it and once DUT get connected to it via mac address we check RSSI and some other features of WiFi of DUT. Now I am wondering is there is any way I can measure throughput of Device under test via mac address of DUT from server side. Test-tool has LINUX fedora 11 in it and major coding is done in c/C++ and json command. Previously, I have tried to install ftp server on test-tool and DUT can connect to it and we can measure the throughput or data transfer rate, but this is not feasible solution as it requires lot of intervention from DUT. What I am interested in is 1) To run some script on server side /test tool and it gives me throughput of bandwidth of connected device may be via mac address of DUT OR 2) Server script transfer some files/packets to DUT and we can measure the throughput. Coding is not a major challenge at this stage , I just need some tool which requires minimum intervention from DUT.

• Create an AWS AMI for Ubuntu with GUI which automatically launches web browser

  - by Rory MacDonald

  I've got an ubuntu AMI setup with ubuntu desktop installed and Chrome installed and set to boot on load (via the startup programmes menu within the ubuntu desktop) I've created an image of this AMI, but any time I launch a new instance running this, the Ubuntu GUI doesn't seem to load, until I SSH into the machine, enable VNC and then connect via Chicken VNC to the machine. At that point, the desktop appears to load + starts the browser. I really need the machine to boot and the browser to load without having to VNC into the machine.. Any help would be appreciated.

• TightVNC (or any VNC) client windows scaling

  - by mr.b

  Hi, I am currently using TightVNC to connect to multiple remote hosts in LAN. I start 16 VNC instances, set Scaling by: Auto (in connection options display), set Hextile encoding, and then select all windows and use Tile Horizontally, which covers my entire screen with VNC screens. It all works sort of nice, except that desktop interaction is really slow when there are more then 4 VNC clients. My question is, does VNC client (not just TightVNC, but any compatible client) support some kind of smart scaling option, so that client tells server something along the lines of: "Okay, I'm displaying your entire screen in a window size 300x225 px, so can you please start sending encoded images on that resolution?", at which point interactiveness of open connections dramatically increase, and when I decide to go full screen on some connection, client and server re-negotiate and server starts sending full resolution images again? Thanks!!

• setting up my own name server

  - by mmokh

  I'm in the process of setting up my own name servers using BIND9, however I want to visualize the name server setup in relation to registrars and other name servers. Say I have a domain www.mydomain.com I setup my 2 name servers: ns1.mydomain.com - 192.168.0.1 ns2.mydomain.com - 192.168.0.2 1) How does the world know that my name servers are now at ns1.mydomain and ns2.mydomain. I read about setting up glue records at my registrar. Could you please elaborate on this, i.e. once i setup these glue records, can I now use my name servers in NS records for any other domain? For e.g. NS records for www.otherdomain.com - ns1.mydomain.com/ns2.mydomain.com 2) Given I setup the glue records as mentioned above, do I "have to" update mydomain.com NS records to point to my name servers? Can I keep mydomain.com NS records pointing to my registrars name servers, however use ns1.mydomain.com/ns2.mydomain.com as name servers for any other domain I own? Thanks

• SCCM for mobile device management returns 404 on /devicemgmt/server.resource

  - by Dan

  We have a new Windows Server 2008 R2 machine onto which we have installed SCCM SP2 followed by the R2 package. We have enabled a mobile device management point and enabled distribution points to support mobile devices as per http://technet.microsoft.com/en-us/library/bb680634.aspx We have also installed the Mobile Device Management Client on to a Windows Mobile 6.1 device. The client on the device fails to connect to the server. Our investigation so far has led us to the URL /devicemgmt/server.resource. However, looking in IIS on the server shows no such URL (in fact nothing apart from the aspnet_client directory) and visiting the URL with a browser returns 404. WebDav is enabled on the Default Web Site in IIS. BITS is installed on the server. Can anyone confirm whether enabling mobile device management will add visible directories to IIS and if so why it might be failing in our case?

• Why the clip space in OpenGL has 4 dimensions?

  - by user827992

  I will use this as a generic reference, but the more i browser online docs and books, the less i understand about this. const float vertexPositions[] = { 0.75f, 0.75f, 0.0f, 1.0f, 0.75f, -0.75f, 0.0f, 1.0f, -0.75f, -0.75f, 0.0f, 1.0f, }; in this online book there is an example about how to draw the first and classic hello world for OpenGL about making a triangle. The vertex structure for the triangle is declared as stated in the code above. The book, as all the other sources about this, stress the point that the Clip Space is a 4D structure that is used to basically decide what will be rasterized and rendered to the screen. Here I have my questions: i can't imagine something in 4D, i don't think that a human can do that, what is a 4D for this Clip space ? the most human-readable doc that i have read speaks about a camera, which is just an abstraction over the clipping concept, and i get that, the problem is, why not using the concept of a camera in the first place which is a more familiar 3D structure? The only problem with the concept of a camera is that you need to define the prospective in other way and so you basically have to add another statement about what kind of camera you wish to have. How i'm supposed to read this 0.75f, 0.75f, 0.0f, 1.0f ? All i get is that they are all float values and i get the meaning of the first 3 values, what does it mean the last one?

• Postfix configuration: different outgoing hosts based on sender

  - by Joe

  I've seen a few answers to this on the web, but nothing definitive nor any good examples. I relay all my mail out through Postfix, currently everything sent to my ISP's mail server. However, there are a few users with gmail accounts or gmail-hosted accounts; I'd like to route their outgoing mail through Google's servers (since it will then appear in their Gmail sent folder). All email NOT from one of these senders should go out through the default relayhost. I believe I need to use the "sender_dependent_default_transport_maps" configuration within Postfix, but can't find a good example on what this setup looks like. Can anyone point me at a specific setup?

• Extra Life 2012

  - by Chris Gardner

  Greetings, It's that time of year again. The time when I beg you for money for charity. See, unlike those bell ringers outside Wal-Mart, I don't do it when you have ten bazillion holiday obligations... Once again, I will be enduring a 24-hour marathon of gaming to raise money for Children Hospital in Birmingham. All the money goes straight to them, and you get to tell Uncie Samual that you're good for that money. I'd REALLY like to break $1000 this year, as I have come REALLY close for the past 2 year to doing so. Don't live near me? Live closer to a children's hospital in the Children's Miracle Network? It's OK. Go find a participant that is working for your hospital and hook them up. Just left me know, I will will join in with the karmic love you will already receive. This year, the event will take place on October 20th, beginning at 8 A.M. Once again, I will try to provide some web streams, etc, if you want to point and laugh (especially if I have to result to playing Dance Central at 4 AM to stay awake for the last part.) Look at it this way, I'm going to badger you about this for the next month. You might as well donate some money so you can righteously tell me to shut the Smurf up. You can place your bid at the link below. Feel free to spread the word to anyone and everyone. I thank you. The children thank you. Several breeds of feral platypus thank you. Maybe, just maybe, doing so will will help you feel the love felt by re-fried beans when lovingly hugged in a warm tortilla. Enjoy your burrito. http://www.extra-life.org/participant/cgardner

• Defining work days and work time

  - by user2553268

  I'm working on development of SMS parking software, and I'm stuck at one point for a month... I need to implement periods of payment (or work time, of a work day, if you will). Here's the problem: For an example, traffic wardens work from Monday to Saturday. From Monday to Friday, the work times are from 07:00 to 21:00, and on Saturday, the work time is from 07:00 to 14:00. The project request was, that the customer can pay parking by SMS unlimited, which I did, but didn't implement this logic. I started with making a table for this periods of payment, it consists of: dayofweek (INT, for use with mysql function DAYOFWEEK, to tell me which day in week is the current date), work_start and work_stop (DATETIME, for defining starting and ending the work day), but I'm unsure if I should use DATETIME, beacuse of the date, or should I use only TIME. The idea is this: If you send an SMS, at 20:50, Monday, it should be valid until 07:50, Tuesday (it's payed by the hour). Extending the time of payment, regarding the work time in week. Currently, it works with extending time by the hour without this rule. Really would use some help, or some ideas, I'm stuck with this for quite some time...

• Why does my wifi fail to stay connected?

  - by Mark0978

  We have 5 different laptops in the house, 1 macbook, 1 Compaq, 3 dells, plus numerous little devices like ipods, squeezeboxs, squeezebox radios and controllers, you name it. All of them connect to and stay connected to the "downstairs" WIFI just fine. But my laptop (the most expensive of the lot) refuses to stay connected, preferring the much weaker and slower signal upstairs. My laptop is running Win7 (64 bit) Ultimate with an Intel 3945ABG WIFI contoller (It's a Dell Precision M6300). The WIFI Access Point is a Cisco WRT54G2 V1 with firmware: Firmware: DD-WRT v24-sp2 (10/10/09) micro Time: 11:11:10 up 42 min, load average: 0.06, 0.01, 0.00 WAN: Disabled

• PowerShell create new Azure VM from uploaded disk (not image)

  - by MikeBaz

  I have a VHD in Azure storage. That VHD is configured as an OS disk through a command like the following: Add-AzureDisk -DiskName $newCode -MediaLocation "http://$script:accountName.blob.core.windows.net/$newCode/$sourceVhdName.vhd" ` -Label $newCode -OS "Windows" I would like to create a new VM pointing at that disk. From what I can tell if I was doing this with an image I would do something like: New-AzureVMConfig -Name $newCode -InstanceSize $instanceSize ` -MediaLocation "http://$script:accountName.blob.core.windows.net/$newCode/$sourceVhdName.vhd" -ImageName $newCode ` | Add-AzureProvisioningConfig -Windows -Password $adminPassword ` | New-AzureVM -ServiceName $newCode However this is wrong for me because I don't have an image - I have a configured VHD that is not sysprepped and can't be. How can I create the VM in PowerShell to point at the existing disk like I can through the portal?

• Need advice for approach for a web-based app that loads excel worksheet but exposes only the charts

  - by John

  I'm looking for suggestions on the Visual Studio approach to take for a web application that is in the conceptual stage. My environment has a lot of tools: Windows Server 2008 R2 Standard 64bit Visual Studio 2010 Professional Edition Sharepoint 2010 Server Enterprise Edition SQL Server 2008 R2 Office 2010 Professional I know I will need this app to retrieve data from a database (or a web service - not sure exactly at this point). The data needs to be placed in an Excel workbook dynamically. The app will need to have a nice user interface (standard web controls - perhaps with some Javascript effects). The Excel ribbon and worksheet grid will need to be hidden. Some web control(s) will cause the Excel chart(s) to be rendered. I am thinking this sounds like Visual Studio Tools for Office (VSTO) so as to leverage .Net and hide Excel. Can you offer suggestions regarding: One ASP.Net Web App Project One Class Library Project for Excel or perhaps which one of the several different Excel 2010 project types (addin, template, document) Would Excel Services for Sharepoint be useful (or required) ? I am feeling a little overwhelmed with so many choices at this early stage of conceptualizing the app. Can you suggest some ideas for this sort of thing? Also, I am a bit more experienced with C# but I've read VB.Net is better for work with the Excel object model. What are general advises with regard to tool choice and overall approach tradeoffs?

• Any InstallPad alternatives?

  - by ianfuture

  Hi, I'm about to install new bunch of software on a Windows XP Pro PC and found InstallPad as a potential method to do it all. However before using it I was wondering if there were any other similar apps that could be better or easier to use? Requirements (should haves more than must haves): - Free - Easy to use and configure - preferably from point and click in a GUI instead of command line params or config files - Robust - bug free or still in active/ongoing development - Some level of support or active community for help or tips - Pre-existing file lists that can be adapted for own use or used outright. Thanks in advance.. Ian

• sudo prompts for password over ssh

  - by Joe Watkins

  I have sudo set up for a shell script as follows on "hostname" (sudo -l output): (suser) NOPASSWD: /path/script* sudoers content is: myuser ALL=(suser) NOPASSWD: /path/script* this works fine, so I can run the following, logged in locally on hostname, without need for password: sudo -u suser /path/script however, when I use ssh (with keys set up, so no password require) to login and run, as follows: ssh hostname sudo -u suser /path/script I get prompted for a password, and when the password is entered I get: Sorry, user myuser is not allowed to execute '/path/script' as suser on hostname. Why? NB the following does not prompt for password at any point: $ ssh hostname $ sudo -u suser /path/script

• OS X Terminal using default ANSI colours for every theme

  - by FrogBot

  For some reason, every theme I palette I've had installed for the OS X Terminal.app has reverted to using the default ANSI colours. The themes have been working fine up until this point and I can't seem to determine what could have caused them to revert in this way. For reference, my standard Solarized Dark colour scheme should look like this … … but it currently looks like this: A quick look in the preferences panel shows that all the colours are correct save for the ANSI colours which have reverted to their defaults. I don't know what other information would be helpful but if you need any other info to help me troubleshoot just ask and I'll update as quickly as I can.

• Troubleshoot odd large transaction log backups...

  - by Tim

  I have a SQL Server 2005 SP2 system with a single database that is 42gigs in size. It is a modestly active database that sees on average 25 transactions per second. The database is configured in Full recovery model and we perform transaction log backups every hour. However it seems to be pretty random at some point during the day the log backup will go from it's average size of 15megs all the way up to 40gigs. There are only 4 jobs that are scheduled to run on the SQL server and they are all typical backup jobs which occur on a daily/weekly basis. I'm not entirely sure of what client activity takes place as the application servers are maintained by a different department. Is there any good way to track down the cause of these log file growths and pinpoint them to a particular application, or client? Thanks in advance.

• Problem inserting pre-ordered values to quadtree

  - by Lucas Corrêa Feijó

  There's this string containing B, W and G (standing for black, white and gray). It defines the pre-ordered path of the quadtree I want to build. I wrote this method for filling the QuadTree class I also wrote but it doesn't work, it inserts correctly until it reaches a point in the algorithm it needs to "return". I use math quadrants convention order for insertion, such as northeast, northwest, southwest and southeast. A quadtree has all it's leafs black or white and all the other nodes gray The node used in the tree is called Node4T and has a char as data and 4 references to other nodes like itself, called, respectively NE, NW, SW, SE. public void insert(char val) { if(root==null) { root = new Node4T(val); } else { insert(root, val); } } public void insert(Node4T n, char c) { if(n.data=='G') // possible to insert { if(n.NE==null) { n.NE = new Node4T(c); return; } else { insert(n.NE,c); } if(n.NW==null) { n.NW = new Node4T(c); return; } else { insert(n.NW,c); } if(n.SW==null) { n.SW = new Node4T(c); return; } else { insert(n.SW,c); } if(n.SE==null) { n.SE = new Node4T(c); return; } else { insert(n.SE,c); } } else // impossible to insert { } } The input "GWGGWBWBGBWBWGWBWBWGGWBWBWGWBWBGBWBWGWWWB" is given a char at a time to the insert method and then the print method is called, pre-ordered, and the result is "GWGGWBWBWBWGWBWBW". How do I make it import the string correctly? Ignore the string reading process, suppose the method is called and it has to do it's job.
