• Ubuntu: Is there a good tabbed PDF viewer?

  - by Frank

  Is there a good non-bloated PDF viewer for (Ubuntu) Linux that supports tabs? I don't want to use Acrobat Reader because it is slow and takes much memory, and my computer isn't the fastest. I know the alternative readers evince and foxit, but they don't support opening different PDF files in tabs. (foxit has that feature on Windows, but the Linux version 1.1, which I just tried, doesn't have it.) For evince, I know many people would like this functionality, but they get ridiculed by Ubuntu people (see here), who say that tabs are the task of a window manager. If that is the case, how can I put all evince windows into one in GNOME?

• MySQL Windows vs. Linux: performance, caveats, pros and cons?

  - by gravyface

  Looking for (preferrably) some hard data or at least some experienced anecdotal responses with regards to hosting a MySQL database (roughly 5k transactions a day, 60-70% more reads than writes, < 100k of data per transaction i.e. no large binary objects like images, etc.) on Windows 2003/2008 vs. a Debian-based derivative (Ubuntu/Debian, etc.). This server will function only as a database server with a separate Web server on another physical box; this server will require remote access for management (SSH for Linux, RDP for Windows). I suspect that the Linux kernel/OS will compete less than the Windows Server for resources, but for this I can't be certain. There's also security footprint: even with Windows 2008, I'm thinking that the Linux box can be locked down more easily than the Windows Server. Anyone have any experience with both configurations?

• pip install very slow through virtual box

  - by AJP

  pip install --exists-action=w -r requirements.txt is very very slow through virtual box. Any suggests of how to diagnose and fix? Would seeing the VagrantFile be useful? VirtualBox 4.2.12 (can't upgrade to .14 as it doesn't work.) Vagrant 1.0.7 Host machine: ProductName: Mac OS X ProductVersion: 10.7.5 BuildVersion: 11G63b VagrantFile contains: Vagrant::Config.run do |config| config.vm.box = "precise64" config.vm.customize ["modifyvm", :id, "--memory", 2048] config.vm.box_url = "http://files.vagrantup.com/precise64.box" config.vm.network :hostonly, "33.33.33.21" config.vm.forward_port 5000, 5000 config.vm.forward_port 5555, 5555 config.vm.share_folder "v-root", "/vagrant", "./" Vagrant::Config.run do |config| config.vm.provision :shell, :inline => "VENV=/usr/local/venv bash /vagrant/setup_env.sh" end end Normal download speed is only about 5 times slower at 0.8 Mb per second versus 4 MB per second (as judged by curling a 50 Mb file from S3). But pip install is taking about 20 times longer from Mac (i.e. about 40 minutes) versus 2.

• Can't add HKCU entries via GroupPolicy Preferences

  - by Lou H

  2008 R2, XP and W7 64 bit workstations. Trying to add/modify two registry entries for Lync2010 for each user. Created using GP Management, User Configuration, Preferences, Registry. If the two registry entries already exist, then the policy works correctly. If they don't exist, nothing changes. GPReults reports it was successful. If I import the .reg file manually, it also works, so I don't believe it is a rights issue. I have tried the Update, Create, and Replace as the Action. I am not familiar with ADM templates, is that the only way to do it?

• What are the mandatory Linux kernel modules to run inside of ESXi

  - by Marcin

  I'm used to rolling my own kernels for servers, as it nicely minimizes the number of exploits (and the resulting patches) to take care of. In a traditional (bare metal) world, the whole process is about knowing what you have (hardware), and what you need (Ethernet, IPv4, iptables, etc.) In a virtualized environment, some things stay the same (still need Ethernet and IPv4), some things go away (power management), and then there are some new needs (vxnet3, or vmware-tools, even though that's compiled outside of the kernel). So my question mostly concerns itself with the last two categories: what can I remove completely, and what new stuff do I want? For example, what IO scheduler do I want, if all my disk operations are going through another filesystem/scheduler/cache to get to the virtual disk? Do I need hyper-threading enabled, or is the VM going to show them to me anyway as a CPU anyway? Do I need Large Receive Offload turned on, or is that something that the hypervisor's network drivers are going to do for me?

• Currently well suited SATA2-SSDs for Laptop usage

  - by danilo

  I am looking for a solid state drive for my laptop. My dillemma: I have been waiting for the new Intel SSDs since Q3/2010, as I've heard they should be better and cheaper, due to lower memory manufacturing costs. Now it looks like the new Intel drives are very fast, but still expensive. I would still buy one of them if I could benefit from the full speed. My hardware only has a SATA-2 port though. Thus, my question: Is it worthwhile to buy one of those new Intel SSDs made for SATA-3 if I won't be able to use the full speed? Are there any other promising new SSDs that will be released soon? (Inside the next 1-2 months) If I wouldn't make a good deal buying the newer, faster drives, what drives can you recommend? I don't consider this question subjective, as I am mainly looking for answers concerning the SATA-2/SATA-3 conflict.

• What features do you want to see in Windows Server?

  - by Ben Herila

  I work for the Windows Server planning and management team at Microsoft. While I can't share any of our current plans right now, I am interested in seeing what features people would like to see in the next release of Windows Server. Please post your ideas as separate answers, and vote for the ones you want to see. If there is an overwhelming response to an idea or two, I'll personally see what I can do to get the feature included. I know this question is subjective, but I do believe this thread has relevance to the community. Looking forward to hearing from you!

• Exchange ActiveSync does not work for one user

  - by jshin47

  One particular user in our system is unable to connect to Exchange ActiveSync via her iPhone. When I try to connect using my own credentials on her iPhone it works (everything begins syncing), but when I input her credentials, the Settings app verifies the credentials are correct but nothing syncs. For example, if I open Mail, no items are shown. When I attempt to force a sync, it says "Cannot connect to server." In Exchange 2010 Management Console the user is no different than the others. Exchange ActiveSync is set as "Enable" in Mailbox Features. EDIT: Alternatively, if there is some easy way to create a new useraccount/mailbox and copy all of the contents of the old one over, I bet it would work, and that would be fine as well. She is a Mac user so we do not have to worry about her Active Directory account.

• Multiple Instances of aspnet_wp.exe?

  - by Mike Keller

  Is this normal? I was poking around Google and from what I found it should be, but we have 60 of them going, and only two .NET apps running on this particular server. All of them are at 0% CPU and at about 3meg of memory usage. We can't really restart the server right now to see if that clears them out, we store a lot of data on it that people need regularly. Any clues for investigating this issue would be appreciated. This particular box is an oldie Windows2000 and .NET 2.0 Thanks.

• IIS Reverse Proxy support for multiple protocols

  - by Abraxas

  I have a server 2012 machine running IIS. It's in my DMZ and I would like to use it to do reverse proxy for several services. I can get it to route traffic on port 80 to 2 separate internal servers running web apps but there are some issues when I try to forward SSH (not port 80/443) and then when I try to forward OWA (Micrsoft exchange's 'webmail' services) to the internal mail server I run in to issues with guides (like this: http://blogs.technet.com/b/exchange/archive/2013/07/19/reverse-proxy-for-exchange-server-2013-using-iis-arr-part-1.aspx) when they say to have all traffic forwarded to the server farm created for OWA. My question for you all is this - given that there is no more Threat Management Gateway (only runs on server 2008) and ISA 2006 is also dead - is it possible to support multiple types of reverse proxies with different protocols (ftp, ssh, web, ssl-web) in IIS, or would it be better to install a different DMZ OS like a nginx server and use linux firewalls + nginx reverse proxy? Thanks for any help!

• Can't login to SQL Server after moving machine to different office/domain

  - by Dan

  Our company has just been bought and the over the weekend I have brought up the last few machines to plug into their network (they are under a different Windows Domain). The last machine is our Vault system and the SQL Server was using Windows Authentication. I have plugged it into their network and its working fine, but i cannot connect to SQL Server with Management Studio and, I fear, no backup jobs will also be working. When I try to login under Windows Auth, it has the user name of "NEWDOMAIN\Administrator" (greyed out) and then presents a "login failed" message with error code "18456". Can anyone help me with this, or will I just have to reinstall SQL Server, Vault and restore the backup I took before the move?

• Links opened by left-click in IE8 take forever compared to middle-mouse button

  - by Bigbio2002

  When I use the middle mouse button to open a link in a new tab, it works instantly. However, if I left-click the link to open it normally, IE8 freezes for about 5 seconds before the popup window opens. I'm sick of all the slowness and the glitchiness and the memory hogging, and I just want it to work as well as all the other browsers out there. Anybody else experiencing this and have any tips? Note: It's not the Java SSV helper or the Skype addon (because I have those disabled). I'm looking for some advanced solutions that I can try. (God, I hate IE8, but I'm a loyal Microsoft follower so I refuse to switch to Firefox. )

• Why cant i install ANY operating system??

  - by Ranhiru

  I tested the memory and i tested the hard disk and everything is fine! Mini XP booted from Hirens Boot Disk works :( I tried Windows 7, Windows XP SP3 and even Ubuntu 10.04 :( All Operating Systems boots up to the point where they can load necessary files to start the OS and then resets the laptop Windows 7, only up to the point where the Windows Loading Animation is happening Ubuntu, only up to the point where the loading is done, shows a small screen and then goes to a blinking cursor and thats it... it keeps on blinking and sometimes resets the computer Windows XP SP3, loads all the drivers and everything and then the point where i should be able install the OS, it simply resets the laptop :( I have used the word reset instead of restart because the laptop completely turns off and then only turns back in Any solutions would be greatly appreciated

• What emulator / VM software can I use to create a Win32-portable Linux Guest?

  - by Jotham

  Hi, I want to create a portable VM setup so that I can boot a Linux install regardless of which Windows XP / Windows 7 host machine I am on. I was looking at Qemu but it doesn't appear to have a relatively safe win32 build. Other things like VirtualBox require complete install on the host OS for performance reasons. I'm not so concerned about performance, I just want to run a few curses based applications. My ideal end goal would be a a memory stick of some size with a VM/Emulator I can boot on most WinXP/Windows 7 machines and access my own curses based applications (probably archlinux or debian). Any help would be appreciated. Regards,

• How many VPS' can I create on my server?

  - by user197692

  I need to create as many VPS's on my dedicated server (KVM or OpenVZ) in order to sell them but I really don't know the answer. RAM calculation is simple, it's more about CPU resources, how many VPS's can hold. I'am talking about Intel i7-2600 (4 cores, 8 Threads). I need to deploy as many VPS's. It's all about the nr threads? i.e. 8 threads = maximum 8 x 1vCPU or maximum 4 x 2vCPU? I'am planning to use 1Gb and 2Gb memory on each VPS, the server has 16Gb (but I can raise RAM if need it. So, can I create 8 KVM VPS's with 4 vCPU and 2Gb ram each ? How about 20 VPS's with 1Gb ram and 4vCPU each? How is this decision affected by the hypervisor (KVM, OpenVZ, VMware)?

• Installing Linux from External Card Reader

  - by Subhamoy Sengupta

  I have this problem. I was experimenting if I could use a memory card (SDHC) as an USB drive for all intents and purposes, and when I put the card in an USB card reader, I can use it just like regular USB stick and it also shows up in the BBS popup menu as an USB stick. When I tried to create an installation media out of it like this: sudo dd if=/path/to/image of=/dev/sdb And tried to boot from it, simply nothing happened. Cursor blinked a couple times, and jumped to the GRUB of my pre-existing GNU/Linux installation. What am I missing here? Is this not doable? I tried this with Xubuntu 12.04 and ArchLinux, by the way. I have also tried UNetBootIn instead of dd. Nothing happened differently.

• Custom one-key keyboard shortcuts in Outlook 2010?

  - by cksubs

  I'm a gmail junkie, and one of my favorite features is the keyboard shortcut "a" inside an email to archive the message. I can't remember if that was the default or if I set it to such a quick little keypress, but by now it's totally ingrained in my memory. I'm setting up Outlook 2010 for work, and set up a similar "quick step" to archive, mark as read, and mark as complete any email. It would be great, except for keyboard shortcuts they only give the option for "CTRL + SHIFT + 1" and other number key options. With a keyboard shortcut that convoluted, I'm not going to remember it and might as well just reach for my mouse. Is there any way to set custom keyboard shortcuts for Outlook 2010? I want one-key shortcuts, not 3-keys-at-once!

• Copying windows 8 Users folder having long long paths

  - by bilal.haider

  I was trying to move my "Users" folder in Windows 8 as described here and here. But when I try to copy the folder using "xcopy" in Windows Installation Disk Repair Mode, after some files are copied, I get "insufficient memory". The files on which the error is given are like C:\Users\Bilal\Application Data\Application Data\Application Data.........Application Data\Application Data..... What is the point in such directories within directories? I also tried copying them using Mini Windows XP, but the problem was there too.. Also tried copying using Parted Magic Live CD... but still.. So now, how can I move them? Another Question. Is moving such/ system files using Linux a good idea? Does it do anything to permissions?

• Macvim lags while Vim on terminal is buttery smooth

  - by SaamJB

  I am running OS X Lion 10.7.3 and Macvim runs significantly slower than vim on the terminal for me. All movement commands in Macvim are much slower. Moving up and down in visual mode is equally as laggy. I see none of this lag when using vim from the terminal. Does anyone know what the reasons may be? I am running NERDtree on every open tab, and I know this contributes some memory overhead and potentially some slow down; but even when I don't run NERDtree Macvim runs much slower than vim from the terminal. Any help in solving this would be greatly appreciated.

• Tools to monitor guest OS performance in vSphere

  - by Quick Joe Smith

  I am looking for some tool or way to retrieve performance data from guest VMs running under vSphere 4.1. I am currently interested in the 4 basic metrics: CPU(%), Memory(%), Disk availability(%) & Network utilisation(Kb/s). The issue I have is that all of vSphere's performance data is from a ESXi host perspective (active, shared, consumed, overhead, swapped etc.) which is far removed from the data from the VM's own perspective. For instance, I have a Windows server VM idling, using around 410MB (~25% of its allocated 2GB) as reported by Task Manager, and this is the value I'm after. vSphere's metrics seem unable to arrive at this figure by any reliable and repeatable means. Is anyone aware of tools that can obtain this kind of data? The simpler, the better.

• Where exactly does a portable app is running when the usb stick is pulled out without closing that app?

  - by Selin Peck

  Where exactly does a portable app is running when the usb stick is pulled out without closing that app? Is it in memory? Is it written the on hard disk as temporary files (where exactly is it, appdata or where)? Does that mean the next user of the pc could gain access just clicking that from the system tray and saving to other folders? How about when the system crash and that portable app is not closed the normal way? On the next open, will it stay somewhere on temporary folders?

• Should I split my website into different servers

  - by Nyxynyx

  I have a website where a user uploads photos, the photos gets resized and thumbnailed, and stored on the server. At the same time, there are some INSERTS into a MySQL table regarding the photo uploaded (like description, user id etc). The site currently runs off a managed VPS, and I love the support it provides. However it is expensive to store the many small photos and the resizing and thumbnailing processes do cause spikes on the app performance. (Amazon S3 is pretty expensive, especially considering the costs for uploading many small files) Question: Will it be a good idea to move the image processing operations and image storage to another server which is an unmanaged dedicated server with a much lower cost/gb and keep the current VPS for its 24/7 support and hosting the webapp? Or should I move the entire site to the dedicated server?

• Need help connecting to SRW2024 Linksys Switch from CentOS 5.4

  - by sxanness

  I am configured a Linksys SRW2024, I accidently changed the management VLAN before changing the VLAN configuration thus I can no longer access it with the net. The only way I have read to get into it now is via a console cable, my laptop with me is a MacBook Pro with no Serial port connection, apart from driving around a town that I am unfamilar with to find an adapter I thought I would try on a Linux box. I have a CentOS 5.4 server here (PowerEdge R300) that I am trying to use to talk to the switch. I tried minicom first but I do not see the console. Another site suggested the screen command. I tried "screen /dev/ttyS0 38400" but all I get is blinking curser, I do not see the configuration. I don't know if anyone here as any tips but I hope someone does. Thank You,

• Ubuntu Server login not recognizing the keyboard after entering username.

  - by Jeff Malewski

  I'm having similar issues with logging into ubuntu server. chief problem is that once I enter my user name & hit enter, I can't enter anything ffor my password - it won't accept any keystrokes until I press Ctrl+any key. Once I've pressed Ctrl+ any key, I'm able to type again, but have never been able to enter any more than 3 characters before the 60 sec time limit. This problem is present on fresh installs of both 10.04 & 9.10. Part of the problem is lkely to be my antique pc which is an old Emachines Trigems I850 based mbd and an equally ancient Nvidia 4x AGP video card. Initially I was going to install Ubuntu 10.10, but with ORCA running with both screen reader and full screen magnification crashed the system & smoked a stick of Rambus memory. Is there any fix to this problem? Jeff
