• Plesk Backup Best Practices?

  - by The MYYN

  My client utilizes Plesk (9.X) for Server Management. We're implementing a custom backup solution, which should include a complete restorable representation of the actual Plesk configuration (Emails, Domains, etc.). We have full access, since it is a dedicated server resembling these steps: Plesk offers some backups, but they do not include the actual content of the (sub-)domains. Browsing the docs and the internet, I haven't found much ideas on that problem. Our target is to have a disaster recovery scenario: Reinstall a clean OS (Ubuntu) from scratch. Install MySQL/PHP and dependencies (since this runs the app) Install a bare plesk Restore all domains + plesk configuration from an archive Continue operations ... Now steps 1, 2, 3 and 5 are trivial. But what are the best practices for step 4? A side questions: Are there any easy-to-use open source apps out there, to create and restore server-images (even on machines with an possible different hardware)? Thanks for your time and input.

• How to adopt scrum agile methodology for a small .Net team

  - by Thabo

  I am working on a small product based company developing .Net applications. There is a small team with 5-6 developers. I am a person responsible for planning everything. But my primary role is Software developer. Now our current project is very unstable because of poor organization. Today my boss called me and told to submit a report about required resources, appropriate methodology, required man power and their salary scales to make the current project success. I know I don’t have enough organization skills and I need to go deep in my programming skills. So I need to focus only in the development. So I can’t manage the project anymore. Now I am searching some other ways to make ongoing development success. My questions are What is the suitable agile methodology to my team? Is Scrum is suitable for above mentioned scenario? If we adopt Scrum, what we have to do next? (I think hiring new one to manage the project is more suitable. So we have to get Scrum master and some other developers.) Are there any resources (books, Blogs and etc) to get some tips and advices to solve this problem? If Scrum is not a suitable methodology for our scenario, what else can be more suitable methodology to adopt? Can anyone give a good solution for my problem?

• How to store 250TB of data and develop a backup/recovery plan?

  - by luccio

  I'm really new to this topic, so big apology for stupid questions. I have a school project and I want to know how to store 250TB of data with life-cycle for 18 months. It means every record is stored for 18 months and after this period of time can be deleted. There are 2 issues: store data backup data Due to amount of data I will probably need to combine data tapes and hard drives. I'd like to have "fast" access to 3 month old data, so ~42TB on disk. I really don't know what RAID should I use, or is here any better solution than combining disk and data tapes? Thanks for any advice, article, anything. I'm getting lost.

• Web Folder size/quota reporting tool?

  - by nctrnl

  I am currently using a Visual Basic script to determine how big the web folders are and what quota is decided for each folder. The quota is in no way a physical limit, just a value inserted by me to decide whether a user is using too much space or not. The script does the job quite neatly and sends an html file by mail on a regular basis. The problem is that it's such a hassle to insert new quotas since I have to fiddle around with the code. A central "control panel" with an overview and ability to insert new quotas would be more suitable. Is there any software that can do the following: Scan specified folder/subfolders Report the file size and present it in some sort of interface (could be a php/mysql solution) Ability to specify a quota and see the difference value ? It is really important that the quota handling is made simple so that some non-technician can handle this.

• Track sales and commission with third-party tool

  - by Andrew

  I have a clothing website where I link to various clothing retailers. I have reached an agreement with one of the retailers whereby they will pay a commission to us for every sale they make from traffic that was referred by our site. I need a mechanism for tracking how much commission should be paid to us, that involves as little work as possible to implement from their side. We both have Google Analytics. Option 1: They record a goal in their GA account whenever someone makes a purchase on their site. They see how many completed goals are marked as referral traffic from our site and calculate commission accordingly. The problem with this is that the whole process of calculating and paying commission will be manual. They will need to frequently check how many sales were generated by referral traffic from our site, and probably we will have to chase them for commission payments. Also - since we won't have access to their GA data - we will need to trust that they report all sales accurately. Option 2: Sign them up to an affiliate network like Commission Junction or Google's Affiliate Network, and connect to them through this network. The problem with this solution is that it seems too heavyweight; ideally we don't want to ask a retailer to go through the whole sign up process just to deal with us and pay us commission. I am assuming that there must be some lightweight service that tracks the number of sales by one site and pays commission accordingly to the other site, where the sign up and installation procedure is simple and fast.

• making cookies persistent in IE8

  - by Jamie Stevens

  There's a website I sign into frequently, and I'm getting sick of entering my username and password every time. The website can remember who I am so long as I don't close my browser (Internet Explorer 8), but when I do it forgets me, and asks me to login again. I'm guessing this is because it's using a cookie (and perhaps a session) that expires when I close my browser. Is there anyway to make this information persistent across each time I load my browser? (I tried exporting the cookies to a file, and then importing them as soon as the browser was reloaded, but that didn't work either... I'm thinking the cookie text file needs to be modified somehow.) (FYI The website is http://blackboard.unh.edu, but you won't have access unless you happen to be a student there :-) NOTE: I'm not interested in using any password remembering features in the browser. The only solution I'm open to is making the cookie / session persistent somehow!

• Windows 2003 - logging off the Administrator account makes web applications inaccessible

  - by Saravana

  Consider a web application installed on a Windows Server 2003 SP2 machine with the admin account. The application is accessible in the server as well as in the network when at least one session of the admin account is logged in. If there are no active sessions of the admin account, the web application is not accessible via the network, nor accessible locally when logged in with another user account. What would cause the web application to be inaccessible there's no Administrator session? Please suggest anything that might help find the solution.

• VLC without chrome in Windows

  - by timberwo7ves

  I'm trying to run VLC (2.1, 64 bit) without any chrome on Windows 7. You can achieve it by going to Preferences, and in the Interface tab, unchecking Integrate video in interface, and also in the Video tab, unchecking Window decorations. The problem lies in the fact that without Window decorations there is no apparent way to move or resize the video window - in GOM player, for example, you can move window by dragging on the video itself; is there an option for this in VLC? Ideally, I would like to move the window by the method described above (by dragging the video), and would like the Window decorations to reappear on mouseover, to allow resizing; I'm a new VLC user, but unsure how far the customisation goes. - I'd settle with just the moving of the window via dragging the video if this is possible by advanced setting. There is a similar question here, but not exactly, and no solution to that particular question.

• Optimal Configuration for five 300 GB 15K SAS Drives

  - by Bob

  I recently acquired an HP Z800 workstation that has five 300 GB 15K SAS Drives. This system will be dedicated to running multiple virtual machines under VMware Workstation (Note: I'm not using ESXi because I do plan to use the system for other purposes.). For the host OS, I plan to install RHEL 5. My number one concern is guest performance. For example, should I create a RAID 10 array for the OS and virtual machine storage with four of the drives and reserve the 5th? Or, is there a solution that will provide better performance?

• Maximum Length Of IP Address: 15 (IPv4) & 39(IPv6)

  - by Gopinath

  Problem You are designing a database table for a web application that requires to store IP address of users who visits the site. The IP address is required to be stored a character data in the table. To define size of the character column you need to know maximum length of IP address. So, what is the maximum length of an IP address? Solution The IPv4 version of IP address is in the following format 255.255.255.255 To store IPv4 address we require 15 characters. The IPv6 version of IP address is grouped into sets of 4 hex digits separated by colons, like the below 2001:0db8:85a3:0000:0000:8a2e:0370:7334 To store IPv6 address you require a 39 characters long column. Conclusion As IPv4 and IPv6 are the commonly use protocols, you better define a column with 39 characters length so that both the format address are saved in to the table without any issues. This article titled,Maximum Length Of IP Address: 15 (IPv4) & 39(IPv6), was originally published at Tech Dreams. Grab our rss feed or fan us on Facebook to get updates from us.

• 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.

• Dedicated Mouse and Keyboard on VirtualBox VM

  - by Myersguy

  Currently I am trying to run VirtualBox on my second monitor, with a dedicated mouse and keyboard. However, doing so has not proven easy. There has been times where the mouse works, but not the keyboard, vice versa, or nothing works at all. The biggest problem I am running into is this: When enabling the USB mouse and keyboard from the VM, I get an error: 'USB Device is busy with a previous request.' The only thing that is using second mouse and keyboard, however, is Windows. The other error I have received stated that the VM was unable to create a proxy for the device. Additionally, the VM occasionally will disable the secondary keyboard entirely, requiring me to unplug and replug it into my PC to re-enable it again. Keyboard auto-capture is disabled, and while a solution I was reading online stated to turn off mouse integration, that option is grayed out on my machine.

• Getting around the FAT32 4GB file size limit

  - by Aesir

  I recently purchased a 32GB USB 3 stick that was formatted FAT32. I plugged it into my computer and attempted to copy a film onto it, the file was over 4GB however and it would not let me copy the file across because of the 4GB file size limit imposed by FAT32. After some googling I found that I could format my USB stick to have an exFAT format which would mean I could put files onto the stick greater than 4GB in size and the drive would work on both my Mac and my PC. The problem with this solution is that my PS3 cannot detect the USB stick when it is formatted with exFAT. I would like to know if there is a way I can have my USB stick formatted so it can have files greater than 4 GB and work on my PC, Mac and PS3.

• Find largest value of integer in repeating string

  - by dotancohen

  I have a script log file that looks a bit like this: 2012-9-16 Did something Did 345 things Script time: 244 seconds 2012-9-17 Did yet something Did another thing 23 times Script time: 352 seconds 2012-9-18 Did something special for 34 seconds 51 times Did nothing at all Script time: 122 seconds I would like to find the largest value of N in the lines Script time: N seconds. However, I need to keep the context, so simply removing all lines that don't contain Script time in them is not a viable solution. Currently, I am grepping for lines with Script time, then sorting those to find the highest value, then going back to the original file and searching for that value. However, if there is a more straightforward way then I would love to know. This is on Vim 7.3 on a recent CentOS. I would prefer to remain in VIM if possible. Thanks.

• Single hardware unit to protect web servers and implement smart publishing

  - by Maxim V. Pavlov

  Thus far we've been using the combination of Forefront TMG 2010 as an edge firewall + intrusion prevention system + web site publishing mechanism in the data center to work with a few web server machines. Since we develop on ASP.NET, we are IIS and in general - Microsoft crowd. Since TMG is being deprecated, we need to come up with a hardware alternative to protect and serve our data center web cloud. Could you please advise a hardware or virtual appliance solution that can provide routing, flood prevention and smart web-site publishing (one IP - many web sites based on domain name filter) all in one. Even if it is hard to configure, as long as it covers all these features, we will invest to learn and replace TMG eventually.

• tcpview cannot kill connection/process

  - by Stig

  I have a program that sometime misses to close a tcp connection. After the program has ended I can see that the port is taken. TCPViewer shows "non-existent" in the "Process" column. If i try to "End process" or "Close connection" nothing happens. If i reboot the server the port is released. But how can I tell Windows to release this port without a reboot? SOLUTION: It was dw20.exe (Microsoft Error Reporting) that was holding it back.

• Diskless with Ubuntu 12.04

• Colored Vertical Lines upon boot and nomodeset DOES NOT fix it

  - by user2851032

  I have installed Lubuntu 13.04 on a Dell Inspiron 1501 laptop, rebooted the machine and encountered this problem. I edited the GRUB configuration to remove "quite splash" and enter "nomodeset", updated grub, and everything was fine. I could reboot the machine without any trouble. However, if I unplug the machine, wait a few seconds, and plug it back in, the problem with the colored lines comes back and nomodeset no longer helps to solve the problem. I tried using radeon.modeset=0 instead of nomodeset and that also works on multiple reboots until I unplug the machine and plug it back in. I was finally able to get around the problem by entering "radeon.exapixmaps=0" instead of radeon.modeset=0. I suppose I kind of made up that boot option using some information from an Arch Wiki page. This would work throughout reboots and even if I unplugged the laptop. It was working fine for quite a while. A few weeks later, I had some unrelated issues with the Java iced-tea plugin, and since 13.10 had just come out, I thought I would try upgrading. So upgrading didn't fix the problem with Java, and after unplugging the machine and trying to use it later, I was back to this problem with the black screen and colored vertical lines. I am completely out of ideas on what to try. It took me a week to figure out how to get it working the first time, but the solution I had isn't working anymore.

• How can I deal with file association in different application(not in Nautilus)?

  - by Julius

  Maybe i don't understand the system. Upgraded to (reinstalled) Ubuntu 11.04. Is there any way the applications can use something that i set in nautilus, or it's just a wrong idea about the usage? In nautilus the file association works great, easy, handy and so on... My first problem was when installed chromium. Downloaded a file, a popup ask for assocation, set nautilus. And it only opens folder, for any file show an error: it is not a direcrory. Ok, so i thought Google chrome changed, because previously .pdf open acrobat,.torrent open vuze and so on. But now i have to open nautilus on download folder with it, than select and open the preferable application by manually and can't use any automatism i used to. Then in gnome commander , it not followed the default association i set in nautilus. Ok maybe it is commander fault. use it's own. Then in calibre, the "read" use again this default "can't open its not a directory" error So it's seems to me the applications not using well this file associations or i really don't understand the aim of file associations system (mime,.desktop files,...) If there is no solution i think i have to search some program (if any exist's) which can identify and launch application and set as default instead nautilus.

• Law of Demeter confusion [duplicate]

  - by user2158382

  This question already has an answer here: Rails: Law of Demeter Confusion 4 answers I am reading a book called Rails AntiPatterns and they talk about using delegation to to avoid breaking the Law of Demeter. Here is their prime example: They believe that calling something like this in the controller is bad (and I agree) @street = @invoice.customer.address.street Their proposed solution is to do the following: class Customer has_one :address belongs_to :invoice def street address.street end end class Invoice has_one :customer def customer_street customer.street end end @street = @invoice.customer_street They are stating that since you only use one dot, you are not breaking the Law of Demeter here. I think this is incorrect, because you are still going through customer to go through address to get the invoice's street. I primarily got this idea from a blog post I read: http://www.dan-manges.com/blog/37 In the blog post the prime example is class Wallet attr_accessor :cash end class Customer has_one :wallet # attribute delegation def cash @wallet.cash end end class Paperboy def collect_money(customer, due_amount) if customer.cash < due_ammount raise InsufficientFundsError else customer.cash -= due_amount @collected_amount += due_amount end end end The blog post states that although there is only one dot customer.cash instead of customer.wallet.cash, this code still violates the Law of Demeter. Now in the Paperboy collect_money method, we don't have two dots, we just have one in "customer.cash". Has this delegation solved our problem? Not at all. If we look at the behavior, a paperboy is still reaching directly into a customer's wallet to get cash out. Can somebody help me clear the confusion. I have been searching for the past 2 days trying to let this topic sink in, but it is still confusing.
