• Lightweight window manager for Linux for Virtual Desktop / Multimon

  - by mattcodes

  Previous used Ubuntu Gnome with Compiz but for my basic spec intel macbook (4 years old) its a little too heavyweight. So for now Im back on my macbook with os x, but now considering going back to Linux. Im looking for a window manager that has the following properties: Supports virtual desktop (need 4 minimum) Works well with multi monitors - can move an app with shortcut from one monitor to the other (on same virtual desktop) Can remember window position (i.e. open vim on 2 monitor) - however must coerce everything back to first screen when 2nd screen is unplugged Keyboard shortcut friendly Not too hard to install Works well with minimum hardware such as integrated graphics Please suggest and share your experiences

• Windows 2008 RC2 IIS6 SMTP Virtual Servers - Limited to 4

  - by webnoob

  In line with this post: http://www.hugheserblog.com/2012/05/22/error-creating-iis-smtp-virtual-servers/ I am receiving the same issues: When we tried to add more than 4 IIS SMTP virtual servers, we got the error within IIS, “The system cannot find the path specified.” This post is almost 2 years old and my server is up to date with Windows updates so I assumed it would be fixed already. Does anyone know if I need to do something special (ie. contact Microsoft) to get a special fix for this? The information in the post suggests it should have been included in an update.

• Moving a Domain Controller VM from one server to another

  - by Mike

  I have a Hyper-V Virtual Machine that is a Domain Controller, specifically it is our main DC and holds all 5 FSMO roles. If I wanted to move this Virtual Machine to another VM Server than the one it is on currently, is it as simple as taking the .VHD, moving it to another server, and creating a VM in Hyper-V on the new server for it? Or are there other things to consider that could get screwed up from doing this? Thanks

• Why is my computer using so much ram?

  - by Ian

  I have 16gb of ram installed in my computer, and nearly 70% of it is used at all times. Looking at the processes in task manager the memory being used with everything in there doesn't even add up to 2gb. I have RAPID mode enabled on my ssd which may be using 2gb at most so I would understand that. I am thinking there might be a memory leak somewhere, but I don't really know how I would be able to tell. My performance and process list is below:

• mod_pagespeed using up too many resources?

  - by OC2PS

  I have found several threads from 2010 and early-2011 talking about excessive resource usage by mod_pagespeed I haven't seen any recent ones. I am facing excessive memory usage, which is causing server to crash several times a day. I am wondering if the issue was ever fixed before mod_pagespeed 1.0 was released. Also, request any tips and suggestion on how to fix the issue. My server configuration: 4 quad-core processors (likely oversold) 3GB memory Xen Centos 6 64-bit Apache cPanel PHP mySQL

• Would it be better to have 10 GB PC5300 or 8 GB PC PC6400?

  - by jayrdub

  My development machine is heavy on memory usage. It currently only has 4GB of PC5300. I'm going to buy 8 GB of RAM, but should I take out all my existing memory and install just PC6400 or leave some of the original and stick with 5300? I don't know if I'll ever need more than 8GB, I might, I'm just wondering if the speed difference between 5300 and 6400 is worth trashing the 2 or 3 GB of old RAM I would still have room for after adding the new RAM.

• centos 5.6, virtual on Vsphere

  - by Glasnhost

  suddenly my virtual centos server (5.6 on VMWare-VSphere) is not working... It started with the url not responding, nor the ip. (NO HTTP response, no ping). When I entered on the server via ssh to start troubleshooting I noticed that most of commands don't work anymore: top- machine hangs (it's not slow anyway) ps - machine hangs (funny enough apache server and web app are running and sending me emails) on some directory ls -l - machine hangs after first file, if ls l.txt the file show only the first file "more" command, also hangs on some file. So there are very little things I can try. I recovered my virtual machine from yesterday and before yesterday, and they show the same behaviour, it hangs on commands (but yesterday they were working). There is no firewall on the machine, there is on the host though. I can connect with ftp but I can't download files nor list directory apart the user top directory... Working hard right now, any idea appreciated

• SQL Express 2008 R2 on Amazon EC2 instance: tons of free memory, poor performance

  - by gravyface

  The old SQL Express 2005 was running on a low-end single Xeon CPU Dell server, RAID 5 7200 disks, 2 GB RAM (SBS 2003). I have not done any baseline measurements on the old physical server, but the Web app is used by half a dozen people (maybe 2 concurrently), so I figured "how bad can an Amazon EC2 instance be?". It's pretty horrible: a difference of 8 seconds of load time on one screen. First of all, I'm not a SQL guru, but here's what I've tried: Had a Small Instance, now running a c1.medium (High Cpu Medium) Windows 2008 32-bit R2 EBS-backed instance running IIS 7.5 and SQL Express 2008 R2. No noticeable improvement. Changed Page File from fixed 256 to Automatic. Setup a Striped Mirror from within Disk Management with two attached 1 GB EBS volumes. Moved database and transaction log, left everything else on the boot EBS volume. No noticeable change. Looked at memory, ~1000 MB of physical memory free (1.7 GB total). Changed SQL instance to use a minimum of 1024 RAM; restarted server, no change in memory usage. SQL still only using ~28MB of RAM(!). So I'm thinking: this database is tiny (28MB), why isn't the whole thing cached in RAM? Surely that would speed up performance. The transaction log is 241 MB. Seems kind of large in comparison -- has this not been committed? Is it a cause of performance degradation? I recall something about Recovery Models and log sizes somewhere in my travels, but not positive. Another thing: the old server was running SQL Express 2005. Not sure if that has any impact, but I tried changing the compatibility level from SQL 2000 to 2008, but that had no effect. Anyways, what else can I try here? Seems ridiculous to throw more virtual hardware at this thing. I know I/O is going to be rough on EBS volumes, but surely others are successfully running small .NET/SQL apps on reasonably priced instances?

• run ubuntu from virtual box in an external hard drive

  - by Bhavan

  I would like to run ubuntu on my external hard drive. I have got virtual box installed in the external hard drive and made a machine named ubuntu and installed the latest ubuntu version which i got from the .iso download. Now after much juggling around i got ubuntu running on the machine which i did the whole installation. When i move it to another machine the virtual box just woudnt open. What is the reason for this and how can i get the ubuntu run from whichever machine i plug in the external usb hard disk. Thanks a lot for your answers in advance. Best regards Bhavan

• Internet connection fails in Ubuntu on VirtualBox when virtual machine is created from "Import appli

  - by Sanoj

  I have installed Ubuntu Server 9.10 in a virtual machine in VirtualBox, then I made a cope/clone and exported it with "Export appliance" so I can create many cloned virtual machines. But when I try to import an appliance, everthing seams to be fine with the Ubuntu except that it can't connect to Internet and doesn't get an IP-address. The machine is used in Bridged mode. And it doesn't help to change to NAT-mode either. The machine that I cloned seams to work fine, and get an IP address. How to fix this? Where am I doing wrong?

• Best way to simulate virtual networks

  - by user179529

  I'm wanting to have a vitual test network on either hyper-v or ESXI ( I Don't care which one) I want to have a multi network virtual environment. Lets say three networks: 192.168.1.0, 192.168.2.0 and 192.168.3.0. I want to use the networks to simulate a multi domain or multi site domain. Whats the best way of doing this. I have VMware workstation but it won't create more then one NAT virtual network. So how would I go about doing this in either Hyper-v 2012 or ESXI?

• Virtual IP, and Reverse Proxying Ports (Making up terms)

  - by macintosh264

  So here is the exact situation that I have I have 2 game servers in my house. One on port 25565, and the second on 25567. I have only one IP in my house I need to get a "virtual IP" for the second server. Some way of giving the computer that runs these game servers a second IP (linux) I need the Virtual IP to receive connections on 25565 and forward the data to 25567. Although if linux recognizes the second IP in networking I assume I can bind to the second IP on port 25565

• How do I enable sound with the "linux-virtual" kernel?

  - by Ola Tuvesson

  I've been trying to enable sound for the linux-virtual kernel as I want to run an ultra slim Ubuntu server under VirtualBox but need audio. The resource usage difference between virtual and generic/server is surprisingly large, with the virtual kernel system using 80Mb less RAM after a clean boot (130Mb vs 210Mb), and I really want to squeeze every clock cycle and available byte I can out of the system. Besides, the virtual kernel has some additional optimisations enabled specifically for virtual machines (or so I am told). Now I have compiled my own kernel a few times in the past, for example to include the Intel-PHC module (for improved power management on Thinkpads), so the concept is not entirely alien to me, but I've run into a strange problem which I'm hoping someone can help explain: When I do a diff between the config files for Linux-generic and Linux-virtual there are precious few differences, and certainly none which pertain to sound support; there are really only five or six lines which differ, and they're mainly to do with i/o timing, sleep state and priorities. What gives? I expected the differences to be extensive, and that I would be able to identify the options that enabled audio by looking at them, but my problem doesn't seem to be related to the config file at all (yes, I know about the sound drivers section - it is identical between the two kernel configs). Am I looking in the wrong place? Many thanks!

• Digital Storage for Airline Entertainment

A weak charge will allow a strong current to flow through. Similar to HDDs, flash memory must provide: Bit error correction Bad block management NAND and NOR memories are treated differently when it comes to managing wear In many NOR-based systems no management is used at all, since the NOR is simply used to store code, and data is stored in other devices. In this case, it would take a near-infinite amount of time for wear to become an issue since the only time the chip would see an erase/write cycle is when the code in the system is being upgraded, which rarely if ever happens over the life of a typical system. NAND is usually found in very different application than is NOR Flash memory wears out This is expected to get worse over time Retention: Disappearing data Bits fade away Retention decreases with increasing read/writes Bits may change when adjacent bits are read Time and traffic are concerns Controllers typically groom read disturb errors Like DRAM refresh Increases erase/write frequency Application characteristics Music – reads high / writes very low Video – r high / writes very low Internet Cache – r high / writes low On airplanes Many consumers now have their own content viewing devices – do they need the airlines? Is there a way to offer more to consumers, especially with their own viewers Additional special content tie into airplane network access to electrical power, internet Should there be fixed embedded or removable storage for on-board airline entertainment? Is there a way to leverage personal and airline viewers and content in new and entertaining ways?

• Drivers for NVIDIA 520M not working in Ubuntu 12.04

  - by Don

  I am aware that this is nominally a duplicate question, however I've read the other questions and haven't been able to resolve my problem after many hours and attempts, so please don't delete it. Additionally, it seems like many answers to the other questions are specifically dependent on certain situations. My situation being different from the others I found represented, here's my question. Until last night, I had Ubuntu 12.04 installed with Wubi, and it ran ok, though slowly and with occasional hangs. So I partitioned the drive and installed 12.04 in its own partition. Now when I start it, I am stuck using 2D. I believe this is an NVIDIA bug. My NVIDIA card is a GT 520M and my machine has Optimus. Additional Drivers only displays my wireless driver. Going to System Settings Details Graphics shows Driver:Unknown, Experience:Standard. I downloaded the driver from the NVIDIA website, and ran the installer with no errors, except that the "distribution-provided pre-install script failed". After rebooting, my screen was stuck at 640X480, which was fixed by editing /etc/X11/xorg.conf However, I still was stuck in 2D, and nothing else had changed either. A thread suggested something called Bumblebee. I tried that, and when I ran optirun firefoxI got a frozen blank screen. Following another suggestion, I checked the BIOS to try and disable Optimus. I found and ran myriad other commands to try and fix the problem and nothing changed. Now I have just done a clean re-install of Ubuntu. From there, I: Installed all the updates Downloaded the NVIDIA driver Installed it Got screen stuck at 640X480, fixed in xorg.conf. To recap the problem: I can't get the NVIDIA drivers working I am stuck using 2D I'm an idiot I think if the first one is solved, the solution to the second will naturally follow. If you need me to provide any other information, I'd be happy to. From what I've seen in other threads, I think this information may help: lsmod: dh@donsMachine:~$ lsmod Module Size Used by nvidia 12353161 0 snd_hda_codec_hdmi 32474 1 snd_hda_codec_realtek 223867 1

• What happened to VM based deployments?

  - by user128670

  Watched some MountainWest RubyConf 2014 talks and noticed an interesting theme. Many dynamic programming environments back in the old days used to be self-contained VM images, e.g. SmallTalk, GemStone/S. One could checkpoint, modify, and ship these images wholesale and have it up and running with very little effort. Fast forward to now and I'm still using Make files to configure and install binaries. What happened?

• Is my computer slow due to lack of swap

  - by Kristian Jensen

  A few months ago, I installed Ubuntu 12.04 alongside with Windows 7 on my Asus EEE-PC 1015bx. It has a tendency of freezing and when trying to investigate I found that a swap partition of only 256 MB had been created. The Asus EEE-PC 1015bx is born with 1 GByte RAM only and it is not possible to add further or exchange the existing 1 GByte with a larger card. When looking at the system monitor, it looks like all swap is being utilized along with 70-75% of the RAM, even with very few applications running. Can the lack of much swap space be the reason for my computer running slowly and at times freezing? How can I add a swap partition? Or should I add a swap file instead? At the moment, I see two partitions when viewing the system monitor: one 28.6 GByte ext4 partition which must be the one containing Ubuntu and one 100 GByte fuseblk partition which I assume is the one holding Windows. It shows that I have 18.6 GByte free space on the ext4 partition. Can I "take a bite" from the ext4 partition and convert this into a swap partition? I was thinking something like 3 GBytes for swap considering my limited RAM. I hope that someone can guide me through. Thank you. 20th Oct 2012 - Further details Thank you for below answer which I find very useful. I am certainly considering switching to one of your suggested shells as I can see from the Internet that many have posted that these require much fewer resources than ubuntu. It seems to me that lubuntu is the perfect match for my very limited computer. I will have to wait a few days, though, as I am presently limited by a very slow and restricted Internet connection via satellite. But will lubuntu install as simply another shell replacing unity or will it replace ubuntu all together? Will the software that I have installed under ubuntu still be accessible in lubuntu? And can I return to ubuntu if required? Regarding the actual question of swap: When I run gparted, it shows me that there is one ntfs partition of 100 GBytes from where it boots and the before mentioned ext4 partition of 28.6 GBytes is not mentioned. Could it be that my ubuntu installation resides inside this 100 GBytes ntfs partiotion? And if so, can I take a bite of this for my swap partition? Realising that gparted is shown in Danish, I hope that you can make out what I mean. System monitoring shows below details: Once again I sincerely hope that you can help. Thank you.

• std::map for storing static const Objects

  - by Sean M.

  I am making a game similar to Minecraft, and I am trying to fine a way to keep a map of Block objects sorted by their id. This is almost identical to the way that Minecraft does it, in that they declare a bunch of static final Block objects and initialize them, and then the constructor of each block puts a reference of that block into whatever the Java equivalent of a std::map is, so there is a central place to get ids and the Blocks with those ids. The problem is, that I am making my game in C++, and trying to do the exact same thing. In Block.h, I am declaring the Blocks like so: //Block.h public: static const Block Vacuum; static const Block Test; And in Block.cpp I am initializing them like so: //Block.cpp const Block Block::Vacuum = Block("Vacuum", 0, 0); const Block Block::Test = Block("Test", 1, 0); The block constructor looks like this: Block::Block(std::string name, uint16 id, uint8 tex) { //Check for repeat ids if (IdInUse(id)) { fprintf(stderr, "Block id %u is already in use!", (uint32)id); throw std::runtime_error("You cannot reuse block ids!"); } _id = id; //Check for repeat names if (NameInUse(name)) { fprintf(stderr, "Block name %s is already in use!", name); throw std::runtime_error("You cannot reuse block names!"); } _name = name; _tex = tex; //fprintf(stdout, "Using texture %u\n", _tex); _transparent = false; _solidity = 1.0f; idMap[id] = this; nameMap[name] = this; } And finally, the maps that I'm using to store references of Blocks in relation to their names and ids are declared as such: std::map<uint16, Block*> Block::idMap = std::map<uint16, Block*>(); //The map of block ids std::map<std::string, Block*> Block::nameMap = std::map<std::string, Block*>(); //The map of block names The problem comes when I try to get the Blocks in the maps using a method called const Block* GetBlock(uint16 id), where the last line is return idMap.at(id);. This line returns a Block with completely random values like _visibility = 0xcccc and such like that, found out through debugging. So my question is, is there something wrong with the blocks being declared as const obejcts, and then stored at pointers and accessed later on? The reason I cant store them as Block& is because that makes a copy of the Block when it is entered, so the block wouldn't have any of the attributes that could be set afterwards in the constructor of any child class, so I think I need to store them as a pointer. Any help is greatly appreciated, as I don't fully understand pointers yet. Just ask if you need to see any other parts of the code.
