• Remote Desktop connection breaks the wireless connection

  - by Michal Talaga

  When I connect to my Windows 8 Professional machine via Remote Desktop (RDP) I almost always get my WiFi connection broken. The setup: T61P Lenovo Laptop + W8 at home Wireless Router with NAT forwards connections to that machine Windows 7 laptop at work connecting to the home laptop When I connect, very often I get to login and suddenly connection is lost and I cannot reconnect again. When I get home I find my WiFi connection is still connected to the Access Point but does not function. Can't even ping the router. What is strange is that disabling wireless with the hardware switch and enabling it again doesn't help. The only way to make it works again: - Reboot - Disable wifi with hardware switch AND disable the network card in Device Manager, then enable both I did not have this problem on the very same laptop when it was running Windows 7. Any hint how can I find where the problem is?

• SEO Blog Indexing : Dot Wordpress Versus a Registered Domain?

  - by rumspringa00

  I've used Wordpress for a few of my client's sites, mostly small businesses and ecommerce sites. I have found through Google Analytics as well as the All in One Webmaster plugin that when it comes to social media, using Wordpress is a surefire way of getting your site indexed by Google and occasionally Bing and Yahoo. Since I am a heavy WP user, I'd like to contribute by registering a dot Wordpress domain for my portfolio. When using a WP installation concurrently with a WP domain, e.g. myportfolio.wordpress.com, will the site be more or less likely to be indexed rather a generic myportfolio.com domain? I've seen mixed opinions where people seem to favor a WP domain for URL output where others say that it's a moot point, and that Google will not favor a WP domain over a dot com domain as long as your meta tags are updated and content is keyword optimized. I tend to disagree and believe a WP domian would more likely be indexed and output more URLs over an individual, laconic domain like myportfolio.com. Am I wrong? Thanks in advance!

• Book / software to learn ERP?

  - by user22311

  For a while I've been wanting to learn ERP. What I would like to do is set up a system, and then practice running a business doing things like generating invoices, raising purchase orders, producing monthly accounts, keeping track of fixed assets etc. Then look at enhancing the system further by adding custom code. I know there are a variety of open source ERP systems around, but really I would prefer a widely used commercial system as having familiarity with such a system would be more marketable. So are there any such systems that have a free developer version available? I've looked around, but I've had trouble finding such a system. Also I would like to find a good book or more likely books to read on ERP. Ideally I would be able to get an indepth explanation ERP from a business perspective, ie the accounting operations it supports, how to do all the regular accounting tasks, configuration, business operations best practices, accounting controls and so on. In addition I would like an IT perspective, ie setting up the system, developing forms and reports. Unfortunately the few books I've looked at have been really superficial and totally inadequate. They either fall into the beginning programmer camp, where they use the programming tools but concentrate on programming 101 topics like loops, flow control etc. Or they cover setting up the system with lots of screen shots, but little substance as to why things should be done a certain way. I have a programming background but no real experience in implementing ERP systems. Also I have a reasonable accounting knowledge, and have used ERP systems in various jobs, but only to a very limited degree. So are there any ERP experts who can point me in the right direction? Thanks.

• Can I share data between two users in an ASP.NET Application?

  - by Dave

  I have an issue with Roles.IsUserInRole function. It take hell amount of time to just check if the logged-in user is in particular role(typ 3-9 sec). I searched to find a solution and arrived on this but I am not sure If I have fully grasped it. What I got from the above, A new derived class is created. Inside that class, there is a list which retrieves all user at once. The next time you check IsUserInRole, you do not use the actual IsUserInRole method but rather use the one you overrode in your class. Is this the correct description? Am I on track? My question is, can data be share between two different users in ASP.NET application? If yes, will the shared data exist only if there is at least one user logged in. If all users logs out, that shared data is destroyed? My point is this data will be created only one time whenever a user logs in. For all subsequent users they can use this data and check their roles against the list? I need a detailed answer. My application has users and different roles. We are using ASP.NET roles.

• Use System Restore to rescue lost user profile in Win XP?

  - by im_chc

  Hi! My win XP account profile has recently been "reset". Many app settings are lost. For example, the "recent project" list in VS 2005 is empty. There should be lots of other stuffs that are painfully lost without me knowing! What can I do? Can I retrieve the app settings from System Restore? I don't have much confidence on this util, even tho I think restoring to a point when the profile still works, and back up away the C:\Documents and Settings (is it where all the app setting files are located?), that should work... Is it reliable to restore to a previous restore pt and then goes back to the latest RP? I've googled on System Restore, looks like what the util does is just back up some physical files, and restore them when doing System Restore. That sounds quite safe, but I am still uncomfortable to this. Thx for u guys' help in advance!

• Why are prefab customizations being applied to only a single character? [on hold]

  - by m0rgul

  I've built my (networked) game to the point where I have a room, some characters and a character customization screen. In the character customization screen I get to chose gender, chose from three different wardrobe options and assign custom colors to these wardrobe items. Then I use a custom object to store these options, serialize them and store them in PlayerPrefs, then load the next scene and apply them to my chosen character in this scene. Then I go and spawn some more characters, customize them, etc. The problem is that my character is always customized, but all other characters in the scene are default copies of the prefab. The prefabs themselves are a generic male and a generic female, both with three different wardrobes to chose from (they are included in the prefab). When I spawn my character, I go to the saved options in PlayerPrefs, destroy the two discarded wardrobes, apply color to my chosen wardrobe and then spawn the character. How would it be possible to make the other characters also show up in their customized form rather than just the generic prefab (which shows all three wardrobes at the same time)?

• Can the JVM(Oracle) run into an OutOfMemory error if the heap size is below the max?

  - by user439407

  I am running a Tomcat site(with an NGinx front end) that seems to be randomly running out of memory even though the max heap size is pretty large. My question is is it possible for the JVM to get an OutOfMemory error even if the heap size is significantly less than -Xmx? For instance, here is a snapshot I took just 15 seconds before an OutOfMemory error: Tue Dec 18 23:13:28 JST 2012 Free memory: 162.31 MB Total memory: 727.75 MB Max memory: 3808.00 MB I guess theoretically it's possible that my code generated 3 gigs worth of objects in 15 seconds, but I highly doubt it. It seems like the JVM was unable to grow the heap even though it theoretically had room....Is it possible that other processes started using memory to the point that the JVM could not grow? I am running 64-bit Oracle Hotspot on a 64 bit vm running CentOS 5 with 6 gigs of ram.

• Ubuntu installer shows three small screens

  - by Sylan

  I'm trying to install Ubuntu (or Kubuntu, which I tried first) 13.04 on a new laptop. I need the install in UEFI mode in order to properly dual boot with Windows 8. I've managed to overcome most of the UEFI issues up to the installer, which appeared as a black screen until I used nomodeset. Now the installer will appear, however it does fit my screen size. Instead, it appears as three small identical screens across the top of the monitor. I thought the problem could be solved by changing the display resolution in GRUB via changing the vga number, but this simply expanded the width of the three screens. While I could install it at this point, the identical screens are too small for me to be able to read the installer. As well, the "Try Ubuntu" option simply gets stuck at a black screen. I'm afraid these problems may persist through the installation if I attempted to continue. Additional information: The laptop is a Lenovo Ideapad Y580 with an i7 3630qm processor, and a GeForce GTX 660m graphics card which works alongside an Intel HD 4000 integrated card via Optimus.

• Right solution for /etc/hosts file reset on reboot

  - by user846226

  i've just installed funtoo and after setting the FQDN on /etc/conf.d/hostname i noticed when setting a list of aliases in /etc/hosts file it get overwtiten on each reboot. Someone points to set the aliases to 127.0.0.2 ip address but that's not a valid solution for me. Could someone point me to the file where i should place entries like 127.0.0.1 local.foo 127.0.0.1 local.bar in order to make them persist in /etc/hosts after rebooting? Thanks! PD: I think openresolv could be the one who is overwritting the file.

• DNS Pointer to old server name

  - by TechKnow Dude

  We have a SBS2003 server that was migrated to a new hardware platform, the computer name has changed but the domain is the same. The desktop's are trying to do offline files to the old server name. There is a nslookup entry for the old server name and a DNS entry for the old server. How do we safely remove the old DNS entry without breaking the computer offline folder storage locally. Can we change the pointing location on the offline file storage to point to the new server name.

• Ultimate way to use Picasa in a home network

  - by luisfarzati

  I've been trying a lot of approaches but still didn't find any effective solution. I want gigs of photos in a network drive (a IOMega Home Media Network Drive, plugged to my wifi router). I'd like to do 2 things: Do a Picasa import process of all the photos in the drive, making Picasa organize all the files in a year/month folder structure physically. Ideally, the import target directory should be the same network drive, otherwise I should move all the imported files in my local computer back to the drive myself. Share the Picasa database over the network, by uploading it to the network drive. Have me and other members of the family point our Picasas to the network database, and see the photos as well as make changes (tag faces, create logical albums, etc) into it. Is ANY possibility to accomplish this? Or should I be looking for another photo management app, and in that case do you know such one? Thank you!

• Excel - Reuse a trend line to apply to other data

  - by milko

  I've obtained a trend line from a particular set of data. What I'd like to do now is to reuse this trend line to predict values from a given pair (x,y) of coordinates. To put it another way, I have one pair (x,y) that I know is correct for sure. I don't know any other point. Let's assume the behavior of this new set is similar to the one I've got the trend line from. Is there any way Excel could compute other points following this trend line?

• Problem with the hosts file under windows 7

  - by martani_net

  I updated some entries in the hosts file "C:\WINDOWS\System32\drivers\etc" to make google for example point to 127.0.0.1 # Additionally, comments (such as these) may be inserted on individual # lines or following the machine name denoted by a '#' symbol. # # For example: # # 102.54.94.97 rhino.acme.com # source server # 38.25.63.10 x.acme.com # x client host 127.0.0.1 localhost ::1 localhost 127.0.0.1 google.com This works fine under windows Vista, but not under Widows 7. When I type google, it goes directly to Google's website. For info, I am not using a proxy server. I think there are some temporary DNS settings that must be flushed, but I don't know how, anyone knows how to fix this? Thank you.

• Is Exchange protected from/allow back dated emails?

  - by David

  Does Exchange Server adequately protect against backdating items in a mailbox folder? I want to determine from an auditing perspective what level of risk exists/what trust can be put into Exchange database records. Is there a (mis)feature that allows end point users to modify the sent/recieved date fields on their own messages? Is there a reasonable way short of hand editing the files for an Exchange Server admin to make such a change? And most importantly: Is there any kind of "sequence number" that we could use to audit Exchange records for evidence of date manipulation (ex. msg100 = Dec 15, msg101 = Dec 10, msg102 = Dec 16)

• License compatibility question

  - by Ivaylo Slavov

  I have a question regarding software licenses. I plan to put a license to a framework that I have written. My intention is that the license should be open, in order to maintain a community. Also I want to control when a new version is released and which changes will be included. The license should allow the framework to be used with commercial products, therefore respecting their own license. I have done some quick research and I decided to double license my work under the Apache License 2.0 (ASL) and Eclipse Public License (EPL). My point is that the EPL will provide me the ability to control the release cycle as well as the contributions to the project and the Apache license will take care for any patents a 3rd party might want to use in a derived work. Also both are open licenses. My question is related to the GLP and LGPL licenses. If I have the above licenses to my framework, will it be possible and legal, for someone to create a derived work of my framework, that is also a derived work of, or links a library that is under the LGPL license? Thanks in advance. EDIT: To be clear I will explain how I expect things to work. The framework will define some common API for certain functionalities as well as a Wrapper class that will invoke an implementation of that API. The Wrapper will be part of the framework, but it will internally call the actual implementation. This implementation should be in a separate library, and such libraries I would like to be developed and maintained by community. Surely the community will have to access the framework but I want to limit changes to the framework by the community but I want to provide freedom for any API implementation (a derived work of the framework). The framework will enable flexible configuration mechanisms that will tell which implementation of an API will be used.

• Tar and gzip together, but the other way round?

  - by Boldewyn

  Gzipping a tar file as whole is drop dead easy and even implemented as option inside tar. So far, so good. However, from an archiver's point of view, it would be better to tar the gzipped single files. (The rationale behind it is, that data loss is minified, if there is a single corrupt gzipped file, than if your whole tarball is corrupted due to gzip or copy errors.) Has anyone experience with this? Are there drawbacks? Are there more solid/tested solutions for this than find folder -exec gzip '{}' \; tar cf folder.tar folder

• Resized Ubuntu 14.04 partition will not boot

  - by user292577

  First, a little background info: I intended to install Ubuntu alongside OS X, but I accidentally erased my entire hard drive and was left with Ubuntu alone. Yesterday, I finally tried to create a desperate partition and OS X. I successfully shrank my Ubuntu partition and created ~40 GB of free space. I used gparted to do this. At first I tried to use Internet Recovery to install OS X on the unallocated space I had created, but discovered I couldn't. I went back to gparted and created a FAT partition with that space. I'm pretty sure I actually did this using my Ubuntu partition on my hard drive (the one I had just shrunken), rather than the USB live boot I had used to shrink it. Therefore, at this point, I think my Ubuntu partition was still functioning properly. I went back to internet recovery and used disk utility to turn the FAT partition into a Mac OS Extended (Journaled) [HFS/HFS+] partition. I believe this is probably where the problem occurred. I successfully reinstalled OS X and found it to be fully functioning. However, when I tried to boot back into the Ubuntu partition all I got was a black screen with a little white cursor (it looks similar to a terminal screen/the Mac DFU mode, but I can't type anything into it. Is there anything I can do to repair my Ubuntu partition? If not, can I at least recover the data from it? Thank you for any help.

• Mapped network drive missing from My Computer and Explorer

  - by matt wilkie

  On a Windows XP Pro SP3 machine one network drive refuses to show up in My Computer or Explorer. The missing drive letter is G:, if that matters. Other mappings work fine. Other profiles one the same machine have no problem seeing G:. I can access the G: just fine typing it into the address bar or in CMD shell. I've used TweakUI to toggle hide/show G: with no difference. TweakUI says G: should be visible. I've logged off,on between toggles to make sure the settings are taking effect. I've looked at reg key [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer] and made sure it's zero'd.ref We've limped along with this broken setup for some time, just working around it, but some applications do not allow typing in a path when choosing a place to save files and it's reached the point where it's intolerable. So, anyone have any idea why XP won't show this drive letter? or how to fix it?

• Exchange 07 to 07 mailbox migration using local continuous replication

  - by tacos_tacos_tacos

  I have an existing Exchange Server ex0 and a fresh Exchange Server ex1, both 2007SP3. The servers are in different sites so users cannot access mailboxes on ex1 as from my understanding, a standalone CAS is required for this. I am thinking of doing the following: Enable local continous replication of the storage group on ex0 to a mapped drive that points to the corresponding storage group folder on ex1 At some point when the replication is done (small number of users and volume of mail), say on a late night on the weekend, disable CAS on ex0 (or otherwise redirect requests on the server-side from ex0 to ex1) AND change the public DNS name of the CAS so that it points to ex1. Will my plan work? If not, please explain what I can do to fix it.

• Less daunting front end for SQL Server

  - by Martin

  We currently have a few users who have been using Access very succesfully to throw around large amounts of data. We've now got to the point where the data is just too large to be held in Access, as well as wanting to hold it in a single place where multiple users can access it. We have therefore moved the data over to SQL Server. I want to provide a general tool that they can use to view the data on the server and do some simple things like run queries and filters and export the data for offline manipulation. I don't want the support headaches that might come with rolling out SQL Management Studio, and neither do I want to have to create an Access database with links for each current database or ones that are created in the future. Can anyone recommend a simple tool that will connect to a server, list all the databases and allow a user to drill into a table and look at the data. Many thanks.

• Multiple redirects with one domain on Apache

• Create Adjustable Depth of Field Photos with a DSLR

  - by Jason Fitzpatrick

  If you’re fascinating by the Lytro camera–a camera that let’s you change the focus after you’ve taken the photo–this DSLR hack provides a similar post-photo focus processing without the $400 price tag. Photography tinkers at The Chaos Collective came up with a clever way of mimicking the adjustable depth-of-field adjustment effect from the Lytro camera. The secret sauce in their technique is setting the camera to manual focus and capturing a short 2-3 second video clip while they rotate the focus through the entire focal range. From there, they use a simple applet to separate out each frame of the video. Check out the interactive demo below: Anywhere you click in the photo shifts the focus to that point, just like the post processing in the Lytro camera. It’s a different approach to the problem but it yields roughly the same output. Hit up the link below for the full run down on their technique and how you can get started using it with your own video-enabled DLSR.

• Why would an ext3 filsystem be rolled back on a Debian VM running in VirtualBox after loss of power to the host

  - by Sevas

  A Debian Virtual machine runs as a Guest VirtualBox VM. It's filesystem is EXT3. The host system loses power and after booting up the host system and guest VM, I find that the VM's filesystem has been rolled back to a previous state, losing changes made to the filesystem some time before losing power. The operations that were rolled back had been fully completed before the loss of power (files fully copied, file handles closed, etc.), but it's possible and even likely that other write operations were occuring on the VM at the point of the crash. So I am trying to figure out if it's the filesystem recovery process that rolls back filesystem operations after encountering corruption post power loss, or is it possibly related to VirtualBox and the way it ignores flush requests for performance gains by default (discussed here) Are there any other factors that would result in the filesystem being rolled back after losing power?

• pfSense router gives DNS rebinding warning when accessing subdomains

  - by Richard Maddis

  I have just set up a router running pfSense on our network and forwarded the appropriate ports. I have a small web server running in my network, and a domain name pointing to our (WAN) IP. When accessing that domain name, everything works fine. However, when accessing a subdomain of the domain name, pfSense will give a DNS rebinding warning. This did not happen back when I used a DD-WRT router. What is the proper way to fix this? The DNS records for the subdomain also point to the same address (I use a virtual server to differentiate the subdomains.)
