• Architectural conundrum

  - by Dejan

  The worst thing when working on a one man project is the lack of input that you usually get from your coworkers. And because of the lack of that you tend to make obvious mistakes. After going down that road for some time I would need some help from the community. I started a little home-brew project that should turn into a portal of some sorts. And the main thing that is bothering me is the persistence layer that i have concocted. It should be completely separated from the presentation layer for starters and a OR mapper is also somewhere. This is because I have multiple data stores that have to be used. So the base idea was that the individual "repositories" operate each on their individual database and that the business layer then aggregates the business objects which are then transformed in the presentation layer into view objects. The main problem I face is the following: Multiple classes for the same concept - There is a DAL representation of a user and BL representation of user and a view representation of a user. I can handle the transformation with a tool but is this really the right way. I mean they are all nicely separated, but the overhead is quite something. What do you think? Am I going too deep into the separation of concern rabbit hole or is this still normal?

• Outlook 2003 drafts folder missing

  - by Michael

  I have a user who has managed to hide her drafts folder in outlook 2003. I have found the following code that works in Outlook 2007, but not Outlook 2003, and I would like to refrain from using 3rd party programs. I did find an article describing how you can retrieve it with a program called MFCMAPI, but I was wondering if there are any other solutions as how to solve it (without reinstalling Outlook)? The mailbox is located on an exchange server and she also has the issue on several computers. However, our exchange guy says that there is nothing wrong with the server. Unfortunately I do not know how it went missing...

• Why is curl in Ruby slower than command-line curl?

  - by Stiivi

  I am trying to download more than 1m pages (URLs ending by a sequence ID). I have implemented kind of multi-purpose download manager with configurable number of download threads and one processing thread. The downloader downloads files in batches: curl = Curl::Easy.new batch_urls.each { |url_info| curl.url = url_info[:url] curl.perform file = File.new(url_info[:file], "wb") file << curl.body_str file.close # ... some other stuff } I have tried to download 8000 pages sample. When using the code above, I get 1000 in 2 minutes. When I write all URLs into a file and do in shell: cat list | xargs curl I gen all 8000 pages in two minutes. Thing is, I need it to have it in ruby code, because there is other monitoring and processing code. I have tried: Curl::Multi - it is somehow faster, but misses 50-90% of files (does not download them and gives no reason/code) multiple threads with Curl::Easy - around the same speed as single threaded Why is reused Curl::Easy slower than subsequent command line curl calls and how can I make it faster? Or what I am doing wrong? I would prefer to fix my download manager code than to make downloading for this case in a different way. Before this, I was calling command-line wget which I provided with a file with list of URLs. Howerver, not all errors were handled, also it was not possible to specify output file for each URL separately when using URL list. Now it seems to me that the best way would be to use multiple threads with system call to 'curl' command. But why when I can use directly Curl in Ruby? Code for the download manager is here, if it might help: Download Manager (I have played with timeouts, from not-setting it to various values, it did not seem help) Any hints appreciated.

• Windows Shares / NTFS permissions on folder redirection in Active Directory

  - by Shawn Gradwell

  A client has folder redirection in AD setup on each user's Home Folder set to the Z:\ drive as \server\share\username. A Group Policy redirects the user's Documents to the user's Home Folder with the option 'Grant the user to exclusive rights to Documents' selected. The share on the server has permissions for the relevant user security group with 'Full Control', but each user's folder only have NTFS permissions only for 'CREATOR OWNER' and 'Domain Admins'. Why can the different users access other user's folders? I thought the most restrictive permissions applied effectively between the share and the NTFS permissions. Also, this setup has been like this for years, and this client recently updated all client computers to Windows 7. What is the best way to setup this redirection now? I assume only in Group Policy, also Basic Redirection - to create a folder for each user under the root path?

• How do I get my server to recognise a change in users?

  - by Gareth

  I'm new in post running a small charity. As a result I've inherited a system from the previous manager that was poorly run. In my enthusiasm to change login details etc. I appear to have killed my microsoft outlook account. When trying to access outlook it prompts me for my user name, domain name and password - which I'm obviously not filling in correctly because it's not accepting my answers. Is there a way to determine that information from the server side? I have access to the server and the staff computers.

• Emulator restarts after snapshot load

  - by reox

  I've set up a android emulator with a snapshot of a specific state i need to go back every time. the snapshot is created and is listed and i can also start directly with this snapshot with emulator -avd MyAVD -snapshot mystate -no-snapshot-save the problem is now that the emulator restart itselfs after i load the snapshot after i did my changes in the emulator. So if i use echo -e "avd snapshot load mystate\nexit" | nc localhost 5554 the snapshot is loaded correctly but then after some seconds i see the bootloader screen. Whats happening there? this phenomen is repeatable with different emulators and different snapshots. is it possible that i just misuse a feature here? edit: it seems this problem is only occuring when i load a snapshot multiple times. after starting the emulator, everything is working quite well. now i load my snapshot, also everything is working well. but when i now load the same snapshot again, it will correctly load it but then the emulator will restart. so is there any possibility to load a snapshot multiple times? otherwise i always need to restart my emulator, which takes a long time...

• Easy Transfer from a dead computer

  - by Nathan DeWitt

  I had a computer that electrocuted me and the company sent me a new one. The hard drive from the old computer works fine and is in my new computer. I would like to transfer my files from the old drive to the new one, preferably using Easy Transfer (old & new computers were Win7). When I go through the Easy Transfer wizard, it assumes my old computer is running and that I can run a process to backup all my data to a single file. However, in my case I have the system drive in my new computer and want to pull the data off it. I would like to avoid rebooting the old computer, to avoid damage to myself or my data. I would like to avoid booting into the old system drive, as my new hardware is significantly different and I imagine I'll run into some missing hardware issues. What's the easiest way to get my data off this drive?

• Factory Girl: Automatically assigning parent objects

  - by Ben Scheirman

  I'm just getting into Factory Girl and I am running into a difficulty that I'm sure should be much easier. I just couldn't twist the documentation into a working example. Assume I have the following models: class League < ActiveRecord::Base has_many :teams end class Team < ActiveRecord::Base belongs_to :league has_many :players end class Player < ActiveRecord::Base belongs_to :team end What I want to do is this: team = Factory.build(:team_with_players) and have it build up a bunch of players for me. I tried this: Factory.define :team_with_players, :class => :team do |t| t.sequence {|n| "team-#{n}" } t.players {|p| 25.times {Factory.build(:player, :team => t)} } end But this fails on the :team=>t section, because t isn't really a Team, it's a Factory::Proxy::Builder. I have to have a team assigned to a player. In some cases I want to build up a League and have it do a similar thing, creating multiple teams with multiple players. What am I missing?

• Monitoring remote laptops

  - by kaerast

  We're looking for something to monitor around 30 remote laptops that are constantly out on the road, never returning to base except for when there are serious hardware faults that need repairing. These laptops won't always be connected to the internet, they'll have mobile broadband and may work offline most of the time. They will be running a mixture of Windows XP, Vista and 7 and there is currently no server setup. We're primarily interested in making sure that Windows Updates and antivirus updates are happening, and I guess we should also be monitoring remaining disk space, what software is installed and ideally hardware health. It might also be nice if we could gain remote access to perform work on them. My main reason for wanting to monitor them is that it's going to be a real pain to get them back to base if anything goes wrong, so I want to be proactive in ensuring they last as long as possible. Can you recommend what I should be monitoring to ensure a long life? What tools would you use to monitor and maintain these computers?

• Efficient splitting of elements in a field

  - by Gary

  I have a field in a text file exported from a database. The field contains addresses but sometimes they are quite long and the database allows them to contain multiple lines. When exported, the newline character gets replaced with a dollar sign like this: first part of very long address$second part of very long address$third part of very long address Not every address has multiple lines and no address contains more than three lines. The length of each line is variable. I'm massaging the data for import into MS Access which is used for a mailmerge. I want to split the field on the $ sign if it's there but if the field only contains 1 line, I want to set my two extra output fields to a zero length string so that I don't wind up with blank lines in the address when it gets printed. I have an awk file that's working correctly on all the other data in the textfile but I need to get this last bit working. I tried the below code. Aside from the fact that I get a syntax error at the else, I'm not sure this is a good way to do what I want. This is being done with gawk on Windows. BEGIN { FS = "|" } $1 != "HEADER" { if ($6 ~ /\$/) split($6, arr, "$") address = arr[1] addresstwo = arr[2] addressthree = arr[3] addressLength = length(address) addressTwoLength = length(addresstwo) addressThreeLength = length(addressthree) else { address = $6 addressLength = length($6) addresstwo = "" addressTwoLength = length(addresstwo) addressthree = "" addressThreeLength = length(addressthree) } printf("%*s\t%*s\t\%*s\n", addressLength, address, addressTwoLength, addresstwo, addressThreeLength, addressthree) }

• How can I be sure that the motherboard is dead and it's not another issue?

  - by Peter

  So I have and old computer with and Intel D101GGC motherboard and a pentium 4 cpu and award bios, with a long repeating beep and not passing POST. I tried: RAM checking, they are good and working on other computers Replacing the PSU with a tested one, and still having the same issue I assumed that the CPU is dead and tested 2 others they are both Celeron D processors I also tested the CPU of this computer on another one and it's working fine I also tried it without RAM and still have the same long beep I did all this after disconnecting all the other hardware like HDD and DVD drives. The only time I didn't get any beeps is after removing the CPU I don't know if the processor is needed for the beeps to work. So My questions are: is it normal to not get any beeps if we don't have a CPU installed ? am I missing something or is the motherboard dead ? and thanks in advance.

• Read a variable from a variable cookie jquerycookie.

  - by Ozaki

  TLDR How could I tell "page.html" which one of 3 or so cookies to look at when the cookie is set on the previous page? Currently: When a link is clicked save text of link to cookie When "page.html" is loaded get the value of the cookie Loads the getjson call as per value of the cookie. E.g: <a href="page.html">link1</a> -c1 <a href="page.html">link2</a> -c2 <a href="page.html">link3</a> -c3 See previous discussion here Now that is all good and well apart from the fact if I were to say open them in multiple tabs. It changes the cookie and correctly loads the right data. But if I were to refresh one of these tabs it will load the most recently open data rather than what it should be. So if I were to save a cookie as c1 with a value of link1 c2 with a value of link2 c3 with a value of link3 How could I tell "page.html" which cookie it should be looking at, therefore not breaking the back/forward/refresh buttons on the browser when multiple tabs are open?

• IIS 6.0 FTP Folder Permissions

  - by Beuy

  I have a IIS FTP website setup like this \ftp\users\domain\public\public Software that runs on clients computers logs into the FTP server by specifying domain\public and moving to public, it then uploads or downloads files / folders into that area. I want to restrict permissions on \ftp\users\domain\public so that nothing/nobody can write files or folders here, only to \ftp\users\domain\public\public. I setup the NTFS permissions of the folder to remove domain\users, public and server\users to not have modify right, yet I can still upload/modify files. I have disabled inheritance from the parent folder of \ftp\users\domain\public as well. Any ideas on what I'm missing here? P.S I know this is a stupid setup and makes no sense, it's some bizarre legacy application that I need to migrate to a safer environment until it can be replaced.

• SQL Server Compact timed out waiting for a lock

  - by jankhana

  Hi all, I'm having an application in that i use Sql Compact 3.5 with VS2008. I'm running multiple threads in my application which contacts the compact database and accesses the row. It selects and deletes those rows in a fashion i.e selecting and giving to the application 5 rows and deleting those rows from the table. It works great with a single thread but if i use multiple threads i.e if 3 or more threads are running I get very often the TimeOut Error!!! I have increased the Time out property in the connection string but it didn't give me expected result. The error log is as follow: SQL Server Compact timed out waiting for a lock. The default lock time is 2000ms for devices and 5000ms for desktops. The default lock timeout can be increased in the connection string using the ssce: default lock timeout property. [ Session id = 5,Thread id = 4204,Process id = 4808,Table name = XXX,Conflict type = x lock (s blocks),Resource = TAB ] The Query that I use to retrieve is as follows: " select Top(5) * from TableName order by id; delete from TableName where id in(select top(5) id from TableName order by id); " Is there any way by which we can avoid this Time Out exception??????? The above query I un as a transaction in VS2008 one using SQLCECommand and the other using SqlCEDataAdapter. Any Idea!!!!!! Reply

• Drupal-- How to place an image in Panels 3 panels and mini-panels, w/o views or nodes?

  - by msumme

  Is it possible, through any modular functionality, to insert an image into a (mini-)panel, either through token replacement, or through an upload dialog, or through a file selection menu? Do I have to use views? Do I have to create nodes? Would the best way be to make a panel node, and then embed it in a mini-node, if I want a block-like panel that can be placed on multiple pages? I want to build a site with images in a particular layout as a small block, and make it very easy for my client to change those images in the future. I can think of some other ways to make this work, but it's driving me crazy that there seems to be no way to simply PUT an image in a mini-panel without having to upload it and hard-code an image tag. And since my client knows no HTML, coding it this way makes it un-helpful for him. And this mini-panel block is going to be used on a number of pages, and needs to be easily modified. I have been googling for about 45 minutes, and come up with nothing useful. EDIT: OR EVEN just put ONLY one image from an image field w/ multiple values in a panel region on a panel node?

• Internet Connectivity Issue

  - by MastaChief11

  Lately, I have been having issues connecting to the internet on one of my computers. The computer I am using now, however, is on the same network as the computer I am posting from. The issues seemed to randomly start about 2 days ago, and the only thing that seemed to fix the issue was to connect to Hotspot Shield VPN. I do not get any yellow warning signs by the Wi-Fi icon in the taskbar. I am sometimes able to use Google search, but I can never go to a website. I am also not able to re-install Hotspot Shield or update Flash because they have to connect to their company's servers. I have tried other VPN services just to see if it would fix anything, but as I expected, nothing changed. I am unsure of how I can fix the issue, and I appreciate all help given. I am running Windows 7 64 Bit Pro on a custom-built computer. Thanks.

• How to copy files between windows 7 professional and enterprise machines?

  - by WilliamKF

  I've got a desktop system running Windows 7 Professional and a laptop running windows 7 Enterprise in a domain-joined computer and I need to copy around 50 GB of files from the Enterprise machine to the professional one. I'd rather not burn a bunch of DVDs or use my tiny flash drive of 1 GB to do the transfer. How can I mount a drive from one of the computers to the other so that I can just drag and drop? I tried using a homegroup, but the windows 7 Enterprise laptop does not see it from the professional desktop and the laptop cannot make its own homegroup since it belongs to a domain.

• Modern monitor technologies - need to find a new monitor

  - by Michal Minicki

  I'm preparing to change my old LCD monitor for a new one. I have an old NEC 20WGX2 Pro based on an IPS panel. I'm looking for a screen that gives good color output but is very good at gaming at the same time (since it is its primary service). I tend to switch monitors between my different computers at home so it has to be multi purpose, hence IPS technology before. Now, where can I read on newest monitor technologies so I can make an informed decision? I need to find a best fit for myself and I have a very outdated knowledge at the moment. So any hints are greatly appreciated, be it info on technologies, web sources, links to other questions, etc.

• Active Directory Support Folder Redirection AND Portable Home Directories?

  - by Robert F

  Does anyone here know if Active Directory will support the use of both Windows Folder Redirection and Mac OS X's Portable Home Directories for synchronizing a user's files to a remote share? I want to synchronize my user's files with a remote share as a way of backing up their data. This is fairly straightforward if a user has only a Windows computer or only a Mac computer. However, will Active Directory support a situation in which a user has both types of computers or they have a Mac on which they're running Windows within Parallels? If I configure a remote share via Group Policies for their Windows files and then configure a different share for their Mac files via ADUC, when they change a file on either computer, will AD know which computer the file was changed on and synchronize that file with the appropriate remote folder? Thanks!

• MySql Query lag time / deadlock?

  - by Click Upvote

  When there are multiple PHP scripts running in parallel, each making an UPDATE query to the same record in the same table repeatedly, is it possible for there to be a 'lag time' before the table is updated with each query? I have basically 5-6 instances of a PHP script running in parallel, having been launched via cron. Each script gets all the records in the items table, and then loops through them and processes them. However, to avoid processing the same item more than once, I store the id of the last item being processed in a seperate table. So this is how my code works: function getCurrentItem() { $sql = "SELECT currentItemId from settings"; $result = $this->db->query($sql); return $result->get('currentItemId'); } function setCurrentItem($id) { $sql = "UPDATE settings SET currentItemId='$id'"; $this->db->query($sql); } $currentItem = $this->getCurrentItem(); $sql = "SELECT * FROM items WHERE status='pending' AND id > $currentItem'"; $result = $this->db->query($sql); $items = $result->getAll(); foreach ($items as $i) { //Check if $i has been processed by a different instance of the script, and if so, //leave it untouched. if ($this->getCurrentItem() > $i->id) continue; $this->setCurrentItem($i->id); // Process the item here } But despite of all the precautions, most items are being processed more than once. Which makes me think that there is some lag time between the update queries being run by the PHP script, and when the database actually updates the record. Is it true? And if so, what other mechanism should I use to ensure that the PHP scripts always get only the latest currentItemId even when there are multiple scripts running in parrallel? Would using a text file instead of the db help?

• What is the simplest, open-source webmail frontend available?

  - by josePhoenix

  I am working on a project to create a few extremely stripped down interfaces for common Web/Internet tasks in order to make computers accessible to my visually impaired grandmother. Currently she uses Mac OS X Mail.app, but I had the idea that I could re-skin a webmail interface running on my own server to make it easier for her to use. The ideal webmail interface to use as a starting point would be without frames or AJAX and written in Python, Perl, or PHP5+, though any setup could work as long as the template and stylesheet files were separate from the application itself. This frontend must also connect to a remote IMAP server, since her email account is with her ISP and not on my server. Can anyone recommend a bare-bones, no-nonsense webmail interface that would work for this?

  I'm a software developer currently stuck to support CyberArk at a large company. I need to pull up a list of accounts that is belong to a certain user. For example, let's said I have a user account named Bob and I want to find all the accounts that belong to Bob in AD meaning on the Organization tab of a user properties, the Manager should be Bob. I've absolutely zero knowledge regarding AD except the very basic. Is there a way to do it? I only have access to "Active Directory Users and Computers" tool and I'm not even sure if I have enough privilege to run script or install powershell to do it but would like to know the script or powershell command to do so if there is one.
