• How to change XFCE to LXDE?

  - by kurp

  I've just installed LinuxMint XFCE, which seems to be still a bit to heavy for my hardware. Thus, I'm thinking about LXDE installation and wonder if a new Linux installation is necessary/advised in such case. The question is: how to switch easily? The additional questions are: a) is it necessary to remove the XFCE packages or both DEs may be installed at the same time? b) is there any way to simply switch between DEs (i.e. have both DEs available and boot with DE selected each time)? c) are there any performance consequences of having more than one DE installed? it means: is clean LXDE installation faster than Linux with 2 separate desktops?

• How to setup certificate authentication for MS SQL server 2008 R2 ?

  - by Stephane

  Hello, I have to connect an (ADO) application running on a standalone Windows 2003 R2 server to a SQL 2008 R2 database that is a member of the domain. I have setup an SQL authentication account for this and hard-coded the password into the connection string but I wonder if it wouldn't be possible to use certificate-based authentication for this instead. I haven't been able to find any documentation regarding this apparently new functionality of SQL 2008 R2 anywhere. Could someone kindly point me at some good documentation ? Or at least a description of the functionality and whether it could be used in my case or not ? Thank you in advance

• Windows System Recovery: Is it needed?

  - by starcorn

  Hello, I just recently deactivated system recovery on Vista, which saved me a huge amount of space. But I wonder is it necessary to have it activated? I can't remember that I any time had any use of system recovery anyway. And since it is Microsoft it probably would do a sloppy job anyway or? This question is for Windows XP, Vista, and 7. Do you have it activated? You can leave a comment if you have any opinion about the system recovery

• Where is the encfs volume key stored?

  - by Waldorf

  I am trying to use encfs in reverse mode. I understand that the passphase is used to encrypt a key which is then stored encrypted into the encfs6.xml file. What I do not understand is the following. Create en encrypted virtual fs of a folder by using passphrase A unmount this folder. Delete all contents including the encfs6.xml file If you then try to do the same with another passphrse I would expect that a new encfs6.xml would be created. However I get the following error message: "Error decoding volume key, password incorrect" So I wonder, what volume key is incorrect, I thought it was in the encfs6.xml file ?

• Outlook 2010 exchange setup prompts for [email protected] rather than [email protected]

  - by Force Flow

  We use a hosted exchange service. When users want to set up Outlook 2010 to access their account, they open Outlook and run through the configuration steps. Autodiscover is enabled, and in the user's active directory profile, their email address is in the email field. However, when the configuration process reaches a point where they are prompted for their email account's username and password, their active directory username is filled in by default instead of their email address. Is there a way to fix that? Users get confused and try to enter their email password over and over again and wonder why it doesn't work (and completely miss/ignore the "use another account" button even though they have instructions right in front of them). I'm also using the Office 2010 ADM's in group policy, but I haven't yet seen an option to specify what gets auto-populated in that windows security prompt.

• Does WD Drive Lock encrypt the data?

  - by ssg

  I wonder if WD Drive Lock ineed encrypts the data on a Western Digital My Book Essential device or just puts a firmware-level password on the device. If it's just a password the data surely could be retrieved by a third party. I could not find anything on about that on user manuals. I found a blog saying "data is secured with AES256" bla bla but that doesn't say anything about if the password could be compromised or not. Because I don't see any delays when I add/remove the password. On the other hand when I enable BitLocker, it takes hours before it encrypts everything with my password.

• Improve my System, Need some advice/suggestion

  - by Pennf0lio

  Processor: 2.40 gigahertz Intel Core2 Duo Board: ASUSTeK Computer INC. P5B-MX Memory: 2 Gb VideoCard: NVIDIA GeForce 7300 GT HDD: 80GB + 250GB both IDE Operating System: Windows 7 32bit Please give me some advice what to improve in my System. I mainly used it for Graphic Design (eg, Photoshop, Cinema4d, Illustrator, Flash). I was planning to increase my Memory adding 2 GB more, Pushing it to something like 4GB in total. But just found out that recently that I already have 2x2GB installed and should be 4GB in total. When I looked at the properties of my computer, It said "Installed Memory 2GB". I wonder why is that happening? Is the other ram broken?.. I never the computer casing since I bought. so I didn't realize that I already have 2 x 2gb ram. what can you advice. Thanks!

• What is magento ecommerce plotting ???

  - by numerical25

  I am not sure if this is the appropriate place to to discuss this issue but I am a Magento developer and ever since they announced they were going to build magento as a PAAS platform, I began to not trust where they are trying to go with the company. As a business I respect where they are trying to go as a company, but as a developer who highly depends on their platform for my business, I feel that they will eventually become a player in their own game. Ebay has announced that they will be acquiring the license to the magento platform and this makes you wonder why a company like eBay would want to do such a thing. Ebay is known for their pre-built stores. it would seem they would only team with magento only to utilize their PAAS web stores. I dunno, maybe I am a little confused about the whole situation. that's why i would like to hear everyone else opinion.

• Do 10m external SAS cables work?

  - by Joachim Sauer

  According to the Wikipedia page external SAS cables are specified for up to 10m length. However, I found it pretty hard to actually find places that sell cables of that length. This made me wonder: Are there any known problems with using cables that are as long as this? Will it be more fragile? Slower? And if 10m is not suggested, would 6m be any more stable? A little background: for several reasons we'd like to put a tape library physically separate from our main server and 10m would be enough to put it on a separate floor.

• EC2-like virtualisation platform with non-RDP access

  - by code'

  I'm looking into setting up a few small VMs. The trouble is the software I intend to install on them (Cisco VPN Client) blocks out networking (other than to the target VPN destination...) with no workaround. This means that Remote Desktop or other methods of connecting to VMs that go via the Internet (e.g. GoToMyPC, LogMeIn) are a non-starter. What I'm really looking for is an EC2-like platform but which gives direct access to the VM through (for example) Hyper-V Manager. Sadly the only way they all seem to offer to remote control the VMs is direct access via Remote Desktop, whereas I need to be one layer above that (if that makes sense). A viable alternative would be to run virtualisation software within a Windows EC2 instance; obviously hardware virtualisation is impossible but I wonder if there are any software virtualisation platforms that could be run and that would work. Does anyone know if something like this exists/is possible? Thanks! C

• Vim: How to create autocomplete/chooser from entries in buffer?

  - by Doug Avery

  Found out today that if you press Ctrl-Opt-Cmd-V in Textmate, it produces a cute little "chooser" dialogue in-place that allows you to page through your recent clipboard entries. It looks very similar to how CTRL-P and -N work in VIM, except it shows whole lines instead of simple word objects. It seems like this would be doable in VIM — it already has a buffer full of entries (the YankRing buffer, for example), and it already has a chooser, but I can't think of where I'd look to start putting these two together. Any ideas? (I know that YankRing already does this by opening a new window full of buffer content, but I wonder if there's a way to do it without all the window switching/closing/etc)

• Way to auto resize photos before uploaded to cloud service?

  - by AndroidHustle

  I love using auto syncing services to have my photos taken with my smartphone stored on a cloud storage service. One problem though is that the photos are uploaded in high resolution and takes up a lot of space on the drive. I wonder if any one knows of a service/strategy to have the auto uploaded photo resized to have it occupy less space when auto stored? That is, without me having to take the photos with lesser quality, I still want photos taken with the highest quality since I may take a photo I really like.

• Windows Server Task Scheduler: Running scheduled executable fail-safe?

  - by Mikael Koskinen

  I have an executable which I've scheduled to run once in every five minutes (using Window's built-in Task Scheduler). It's crucial that this executable is run because it updates few time critical files. But how can I react if the virtual server running the executable goes down? At no point there shouldn't be more than 15 minutes break between the runs. As I'm using Windows Server and its Task Scheduler, I wonder is it possible to create some kind of a cluster which automatically handles the situation? The problem is that the server in question is running on Windows Azure and I don't think I can create actual clusters using the virtual machines. If the problem can be solved using a 3rd party tool, that's OK too. To generalize the question a little bit: How to make sure that an executable is run once in every 5 minutes, even if there might be server failures?

• Can Windows 7 or Vista's Snipping Tool capture a screen 10 seconds later, and capture the mouse poin

  - by Jian Lin

  I wonder if Windows 7 or Vista's Snipping Tool can capture a screen 10 seconds later, and capture the mouse pointer as well? The thing is that sometimes we need to capture the thing that "pops up" when the mouse is over it, so in that case, Snippling tool won't seem to work (because the mouse pointer is activating the Snipping tool instead of pointing at the thing to get the "pop up" item). In this case, the key PrtScn on the keyboard can capture the screen to the clipboard, except it won't capture the mouse pointer, which is sometimes wanted... Is there a way to do that, and possibly say, "capture the screen 10 seconds later, when I am all ready?" thanks.

• Keeping rackspace vserver alive

  - by mit

  It appears to me that rackspace somehow freezes cloud VMs after some idle time. This means the first page request to a php page takes much longer to respond than the subsequent requests. I am actually querying a machine with wget from a different host now to keep it "alive". But I wonder what frequency would be necessary. Does anyone know the time period after which they send a VM to "sleep"? I guess it would be some minutes. EDIT: There is no caching involved on the php site. It just recently moved from another vhost and there was never such latency on the first request.

• Is it possible to create a delta VM?

  - by iTayb

  I have a VM of approx. 18GB. Sometimes I need temporally clones of it, so I clone it. The problems are: * It takes a while until it's done. * Sometimes I happen to need dozen of clones and I'm running out of storage. I wonder if there's a way to create a VM that saves only the delta (difference) since the delployment out of the source machine. That way each new VM's filesize should be 100MB at most, and creating it will be much faster. I've heard that VMWare View is using this concept. Is such a thing possible for ESXi as well? I'm using ESXi 4.1 with VSphere 4.1. Thanks!

• pure-ftpd: one readonly/non-deletable file in home directory

  - by Bram Schoenmakers

  Is there a way to have a file in the user's FTP home directory without the ability to modify/remove it from that directory over FTP? So the user has write permissions on his own home folder, thus the ability to remove files. An exception should be made for a single file, which has the same filename and contents for each account. The solution I'm thinking of right now to run a periodic script to check the presence of that file, and if not, put it back. But I wonder whether there's a better solution than this.

• Longlasting Macport installation

  - by user10826

  Hi, I use Macports on Mac OSX to install some software. But there are somethings that I find very strange. For instance, yesterday I installed some app. and the it needed to get gcc43 and compile completely from source! It took a lot of time, although now everything works right. I understand that compilation of everything in the gentoo spirit is eomthing nice, but in the Mac case, not necessary. There are ony sole hardware variations, so it will be easier to get the binaries. I wonder if Macporst can be forced to get the binaries when available and therefore avoid these time consuming compilations. Thanks

• Cannot find the 2nd datastore after upgrading ESXi 3.5

  - by aXqd

  I have an ESXi server (version 3.5) with about 60 VMs. It has 2 hard disks, each of which is regarded as a datastore. After upgrading through 'VMware Infrastructure Update' tool(still staying with 3.5 instead of 4.0) and a reboot, I can only see the 1st datastore. Hence many VMs are, now, inaccessible. I wonder how I can get the 2nd datastore back. I am sorry, but I did't have the 2nd datastore backuped before. BTW, I am still thinking of upgrading directly to version 4.0 to see if it can fix the driver problem. How about that?

• There is not enough space on the disk when there is?

  - by Lee Tickett

  Permissions are fine (inherited) and checking effective permissions everything is AOK. As you can see i can make a file in the docs folder but not the pdf_docs subfolder. The folder has a lot of files and is quite large- i wonder if i've reached a limit? I couldn't find anything on google. Size: 51.0 GB (54,819,804,885 bytes) Size on disk: 52.0 GB (55,925,719,040) Contains 554,697 Files EDIT I've just checked and i can delete files... and for every file i delete i appear to be able to create a new one. This definitely points toward a limit in terms of number of files?

• Is FreeBSD more suitable than CentOS for firing 40k concurrent connections (for Jmeter)?

  - by blacklotus

  Hi, I am trying to run Jmeter to simulate 40k concurrent users and stress test a particular system. Putting aside the possibility that Jmeter may not be able to push such a high number (although I have read that it is at least possible to handle 10k concurrent threads on a very powerful machine), is FreeBSD a more suitable OS as compare to CentOS to be used for my Jmeter machine for handling 40k (or as high as possible) of concurrent outbound connections? Reason for asking this is that, I have found articles on FreeBSD for tuning and optimizing for maximum outbound connections, but seem to have little luck with CentOS. It makes me wonder if for some specific reasons, people don't use CentOS for such high number of outbound connections. Personally however, I am more familiar with CentOS and would like to stick with it if possible. Any input is greatly appreciated!

• What is the simplest and fastest way to transfer large file through a Windows network?

  - by Sake

  I have a Window Server 2000 machine running MS SQL Server that stores over 20GB of data. The database is backed-up every day to the second harddrive. I want to transfer those backup files to another computer to build another test server and for recovery practicing. (the backup never actually got restored for almost 5 years. Don't tell my boss about that!) I have trouble transfering that huge file through the network. I've tried plain network copy, apache download, and ftp. Any method I tried end up failing when the amount of data transfered reach 2GB. The last time that I successfully transfered the file, it was through a usb attached external harddrive. But I want to perform this task routinely and preferably automatically. Wonder what is the most pragmatic approach for this situation ?

• Using off-the-shelf hardware for brand-name servers; Possible? Good idea?

  - by threecheeseopera

  Is it possible or advisable to use 'regular' not-sanctioned-by-the-server-manufacturer hardware in high end servers? Often these manufacturer-supplied parts have a very high price markup, and I wonder if it's always necessary (understanding that they probably apply more rigorous requirements to this hardware). For example, Dell sells 300GB 15,000rpm serial-attached scsi drives for a certain server family for almost $600 each, while newegg sells a drive with the same specs for almost half the price http://www.newegg.com/Product/Product.aspx?Item=N82E16822116059. Do we really need to pay these high markups, especially for disks that are likely RAID-ed and so guarded against catastrophic failure?

• concrete uses of LDAP?

  - by ajsie

  im new to LDAP. i wonder what are some concrete examples of using LDAP. things that are MUCH more easier to do when you got 3-7 linux computers in a small company network. one use that is very important for me seems to be that you configure LDAP to handle system authentication. then you dont have to create same accounts in all computers. are there other things that are a MUST DO for a small network to save more time? my small network is for apache servers and database servers. and should LDAP be in an own machine? cause i guess its not good to put it in apache or database servers since these are performance dependent.
