• IDC Recommends Oracle Solaris 11

  - by user12611852

  IDC published a research report this week on Oracle Solaris 11 and described it as "Delivering unique value."  The report emphasizes the ability of Oracle Solaris to scale up and provide a mission critical platform for a wide variety of computing. Solaris built-in server and network virtualization helps to lower costs and enable consolidation while reducing administration costs and risks. Learn more about Oracle Solaris and the recently announced 11.1 update. In their conclusion, IDC reports: Today, Oracle is a multi-OS vendor that is adjusting to the opportunities presented by a significantly expanded product portfolio. The company has a long history of supporting Unix operating systems with its broad product portfolio, but the main difference is that now Oracle has direct control over the destiny of the Solaris operating system. The company has made a strong commitment to Solaris on both SPARC and x86 systems, as well as to Linux on x86 systems, and expects to continue to enhance Oracle Solaris 11 with update releases once a year as well as Solaris 12, which is already on the road map. Oracle is working to help its customers understand its strong commitment to Oracle Solaris and the product's role as a single operating system that runs on both SPARC and x86 processors. While Oracle Solaris and Oracle Linux are critical assets, the company's crown jewel is the deep collection of software that runs on top of both Oracle Solaris and Oracle Linux, software that creates a robust application environment. The continuing integration and optimization of the software and hardware stack is a differentiator for Oracle and for customers that run an Oracle Solaris stack.

• Wordpress Installation on Two Servers - Loadbalancing

  - by rihatum

  Hi All, I have to install wordpress (One Blog, one domain, for e.g. mycompany.com/blog) on two servers sharing one database on a different server, these two servers are behind a loadbalancer and the db would be on another server. We are planning this way due to high traffic. I have done standalone wordpress installations on a single server, on windows 2003, 2008 with IIS6, 7 etc I am just researching as to how would I implement this. What would be the steps to achieve this and upon searching I saw some posts regarding the wp-content/uploads directory to be synced at regular intervals ? your help much appreciated Thanks for reading

• How to block/redirect hosts and subdomains of a host using htaccess?

  - by Sven

  I want to block several host-domains and their subdomains, as well as IP-Adresses using htaccess. So far I added to my .htaccess-file: # block doamins and all subdomains Deny from .example.org # block domainrange: 1.2.3.[1-255] Deny from 1.2.3. # Block single IP Deny from 2.3.4.5 but still I had problems with spam from e.g. server1.example.org. What is wrong with my script? Is it also possible to redirect all requests from certain hosts/IPs to a document (say: info.html)?

• Is it possible to get xRandR to see two separate outputs with the nvidia driver?

  - by rumtscho

  I have two monitors, which I have set up with nvidia-settings in Twinview. The result: When I want to do something in xRandR, it does not function. It doesn't report one output per video card head, but a single output mapped to the combined area of both monitors: rumtscho@bradbury:~$ xrandr xrandr: Failed to get size of gamma for output default Screen 0: minimum 3840 x 1440, current 3840 x 1440, maximum 3840 x 1440 default connected 3840x1440+0+0 0mm x 0mm 3840x1440 50.0* Now I promised somebody to help test a driver. The developer is using an open source driver for Intel video cards, and his driver assumes that there is more than one xRandR output, each mapped to a monitor. So I tried rewriting my xorg.conf to somehow get two outputs to show up, but failed. Googling showed that people faced with the xRandR-nvidia problem either stopped using xRandR and achieved what they needed with nvidia-settings, or changed their driver to nouveau. The first is not going to help in my situation, and I am not willing to give up the proprietary driver, because Compiz won't work without it. So does anybody know a way to get nvidia to actually pass on information on outputs to xRandR?

• Practical way to set up an email inbox for testing?

  - by Ben Collins

  I need to test a high-volume email application. Up to now, I've just been using gmail ad-hoc aliases ([email protected]) to receive emails and see that the content is right. However, I now need to verify a recipient list, which means I need to get every single email that goes out on a particular test run. The problem with Google isn't clear, but there's some throttling somewhere (perhaps from SendGrid, who is my delivery provider), and only a very small number of those emails ever make it to my acount. So: what's a practical way to get where I want to be? Is there a way to get gmail to just accept everything? Is there a web app / service somewhere that will let me throw up a fake email address that can receive for a large number of recipients? Is there something else?

• Managing many draw calls for dynamic objects

  - by codetiger

  We are developing a game (cross-platform) using Irrlicht. The game has many (around 200 - 500) dynamic objects flying around during the game. Most of these objects are static mesh and build from 20 - 50 unique Meshes. We created seperate scenenodes for each object and referring its mesh instance. But the output was very much unexpected. Menu screen: (150 tris - Just to show you the full speed rendering performance of 2 test computers) a) NVidia Quadro FX 3800 with 1GB: 1600 FPS DirectX and 2600 FPS on OpenGL b) Mac Mini with Geforce 9400M 256mb: 260 FPS in OpenGL Now inside the game in a test level: (160 dynamic objects counting around 10K tris): a) NVidia Quadro FX 3800 with 1GB: 45 FPS DirectX and 50 FPS on OpenGL b) Mac Mini with Geforce 9400M 256mb: 45 FPS in OpenGL Obviously we don't have the option of mesh batch rendering as most of the objects are dynamic. And the one big static terrain is already in single mesh buffer. To add more information, we use one 2048 png for texture for most of the dynamic objects. And our collision detection hardly and other calculations hardly make any impact on FPS. So we understood its the draw calls we make that eats up all FPS. Is there a way we can optimize the rendering, or are we missing something?

• Linux: Limiting data throughput (pipe) in bytes per second?

  - by sdaau

  Hi all, I was wandering if there is a Linux program that can limit data throughput of a pipe - in actual bytes per second?. From what I gather, applicable for the purposes would be bfr, however, it has been removed from Debian (Removal candidate: bfr) cpipe, however, it seems the lowest resolution it will support is kB/s, meaning that buffer writes can still reach MB/s ([SOLVED] Is there a program to limit terminal pipe speed? - Page 2 - Ubuntu Forums) What I'd want is to be able to specify something like cat example.txt | ratelimit -Bps 100 > /dev/ttyUSB0 ... and actually have a single byte from example.txt sent each 1/100 = 0.01 sec (or 10 ms) to 'output'.. Thanks in advance for any suggestions, Cheers!

• Allowing outbound traffic with APF/iptables for OpenVZ container

  - by David

  I have apf installed on a OpenVZ container (proxmox 2.1). The config is pretty much vanilla and things are working. My external services like ssh and http are working. My problem is that all outbound traffic on http/https is blocked. How do I allow all outbound traffic for http/https. If I change EGF to 1 like this, all inbound and outbound traffic gets blocked EGF="1" EG_TCP_CPORTS="21,25,80,443,43,53" EG_UDP_CPORTS="20,21,53" EG_ICMP_TYPES="all" I opened a single outbound rule with the following # /usr/local/sbin/apf -a downloads.wordpress.org How do I allow all outbound traffic on http/https without blocking all traffic? Why would I allow all inbound ssh/http traffic and block all outbound traffic?

• Dynamic Subdomains

  - by crash

  On my new site I want to have dynamic subdomains. I'm trying to make it so that the subdomains use the same web root as the main domain, all under a single CodeIgniter installation. For example, subdomain.example.com would lead to example.com/subdomain, which is actually example.com/index.php/subdomain. I've already the DNS, virtual hosts set up but I"m getting caught up on the .htaccess. The effect of the linked htaccess is that when navigating to any subdomain, it gets caught up in an infinite loop. (Error log after one request.) It's the same effect for www., which should just resolve to the main domain.

• Intuitive view of what's using the hard drive so much on Windows 7?

  - by Aren Cambre

  Sometimes my hard drive usage is near 100%, and I have no idea what is causing it. Are there any utilities that can help diagnose excessive hard drive usage and have as intuitive of an interface as Task Manager's Processes tab, which I can sort by CPU usage? I am aware of using procmon, of adding columns to Task Manager's Processes tab like I/O Read Bytes and I/O Write Bytes, and using Resource Monitor's Disk tab. Too often, these don't give me useful information or clearly identify a single process that is hogging the disk.

• two identical broadband lines working as one

  - by Katafalkas

  I have been trying to find an answer to this, but all I get is hobbyists trying to connect they linksys's and get some magic out of it. So I am thinking of a way I could combine two 100Mbp Fiber Optics lines into a single connection for our office. I assume it involves some CISCO learning or something like this. Was thinking that I might need to configure some big router to load-balance the NAT'ing in some way. I assume that meny of you have done something similar and maybe someone could share the knowledge or at least provide some tips ?

  Earlier this week we asked you to share your tips and tricks for setting up a novice-proof computer; read on to see how your fellow readers ensure friends and relatives have a well protected computer. Image available as wallpaper here. If you only listen to a single bit of advice from your fellow readers, let that advice be the importance of separate and non-administrative user accounts.

I have to install software for them, but they can’t break the machine without causing physical damage (hammers, water, etc.) My wife was on Windows, and I was on Debian, and before they had their own, they knew they could only use my computer, and only logged in as themselves.

• Private Git repo using Smart HTTP with LDAP authentification

  - by ALOToverflow

  I've been crawling the interwebz and getting my hands dirty for the last few days, but I can't seem to make it all work together. I managed to get a HTTP repo working with Ubuntu 10.04 over Smart HTTP (pull and push over HTTP) for a single repo. This means that I do the initial setup over SSH to the server (git init --bare) and after that the clients can pull and push to it (git clone http://servername/allgitrepos/repo.git). Unfortunately it's impossible to add a new repo without SSHing to the server and adding it manually) i.e. git push http://servername/allgitrepos/repo2.git (allgitrepos is available for everyone to read-write and execute) would fail talking about git update-server-info (which seems to be a general error message). So far the repository is anonymous, so I would like to authenticate using LDAP and also use the LDAP creds to make the git commit. So, how can I push new repos to the server and how can I use the LDAP creds to make the git commit. Thanks

• Why are my Google and Bing search result pages locking up?

  - by Cyberherbalist

  I've got some really weird behavior going on. I can't do any web searching using Google or Bing because when the search result page shows up, every single link on the page is completely unresponsive. That is, every link to a search result. The links to page functions other than search results work fine. This happens in both IE9 and FF13. It doesn't happen to Yahoo! results, though. Any ideas?

• Can't find new.h - getting gcc-4.2 on Quantal?

  - by Suyo

  I've been trying to compile the Valve Source SDK (2007) on my machine, but I keep running into the same error: In file included from ../public/tier1/interface.h:50:0, from ../utils/serverplugin_sample/serverplugin_empty.cpp:13: ../public/tier0/platform.h:46:17: new.h: No such file or directory I'm pretty new to C++ coding and compiling, but using apt-file search I tried to use every single suggestion for the required files in the Makefile (libstdc++.a and libgcc_eh.a), and none worked. I then found a note in the Makefile saying gcc 4.2.2 is recommended - I assume the older code won't work with the newer version, but gcc-4.2 is unavailable in 12.10. So my question/s is/are: If my assumption is right - how do I get gcc 4.2.2 on Quantal? If my assumption is wrong - what else could be the problem here?

• Using 4 monitors with 2 generic video cards... possible?

  - by Ikram

  I'm thinking of setting up 4 monitors in a grid, using two video cards, one card to feed each pair of monitors through the card's two DVI ports. The most important requirement for me is to have the grid of monitors act as one single huge screen. Is this scenario possible by using two generic cards like Radeon 4870s on a Windows 7 computer? (I've heard of Eyefinity, but 4870s don't have it) Another issue is that I only have one PCI-Express slot on my computer's motherboard, therefore I'll need to use one of the lesser PCI cards as the second video card. Will this pose problems?

• Memory allocation strategy for the vertex buffers (DirectX 10/11)

  - by Alex

  I have the following question. I write CAD system. So I have a 3D scene and there are many different objects (walls, doors, windows and so on). User can add or delete some objects. The question is: how can I organise the keeping of vertices for all my objects. I can create vertex buffer for every object. But I think drawing/switching from one buffer to another would have performance penalty. Another way - I can create several big buffers for every object type. But I don't understand how to update such buffers. It is too big to update whole buffer (for example buffer for all walls). What I need to do if I want to delete the object from the middle of the buffer? Actually I have the similar question: http://stackoverflow.com/questions/5515700/how-to-properly-update-vertex-buffers-in-directx-10 Most examples I've found work with very static models. Therefore, they tend to create a single vertex buffer with their list of points, and then are just manipulated by matrix transformations. I, on the other hand, will be updating the scene very often.

• Dedicated Servers: Is one better then two for LAMP pseudo HA setup? [closed]

  - by bikedorkseattle

  Possible Duplicate: How to find web hosting that meets my requirements? I know there are zillions of commentary about hosting out there, but I haven't read much about this. Our current well known host is having too many problems, the hardware we are on it subpar, and I'm ready to leave. A day of downtime can cost as much as our monthly hosting bill. A month of bad performance is just killing us right now, user and google wise. I'm wondering about running two dedicated boxes for LAMP, one running as the primary Nginx/Apache (proxy pass), and the other as the MySQL box. Running a single box scares the bejesus out of me because who knows how long it will take anyone to fix a raid card or whatever. The idea is to set this up using some sort of failover system using pacemaker and heartbeat. If one server goes down the other can take over for the other running both web and db. There are some good articles over at Linode about this. I have a few DBs that are 1GB+ and would like to load them into memory. Because of this, I'm shying away from a Linode HA setup because for the price I could do it with two dedicated like I described. Am I mad or an idiot? What are people out there doing for pseodu high availability good performance setups under $400/month? I'm a webmaster; I do a lot of things none of it that well :)

• VMware virtual network adapters and Windows Firewall

  - by anonymous

  I am running VMware Workstation 7.1.4 on Windows 7 Enterprise SP1-U (x64). Aside from the physical network adapter, I have created a single virtual network adapter (VMware Virtual Ethernet Adapter for VMnet1) which is connected to (can be seen by) the host and the guests. My problem is, even after applying the "*NdisDeviceType = 1" tweak to the virtual adapter, making it disappear from the Network and Sharing Center, I still can't connect to programs running in the host from the guests, unless I specifically "allowed the program to communicate with the public network" using the Windows Firewall (which I don't want to do). This happens to all the programs and services running in the host (File and Printer Sharing, Database server, HTTP proxy, etc.) I am getting the impression that applying the "*NdisDeviceType = 1" tweak only hides a network from the Network and Sharing Center but not actually making it private. Any hints and suggestions?

• emulate dual monitor using a second machine

  - by Hemal Pandya

  I have monitors of my two machines side by side and I use them both with a single keyboard/mouse using Synergy+ (now hosted at Google Code) which works great. But is it possible to use the monitor of my secondary machine as the secondary monitor of my primary? I am on XP so from what I understand I cannot just rdc from secondary to this primary. In any case that would be a different session altogether and I would prefer to be able to extend my desktop over the two monitors. Any solutions or suggestions? Thanks in advance.

• Windows 7: enabling navigation of subfolders in pinned Start Menu folders

  - by AspNyc

  I'm just about to move from Windows XP to Windows 7, and I'm struggling with some of the interface changes. In XP, I was able to throw a folder intoC:\Documents and Settings\username\Start Menuand have it appear on the Start Menu, complete with the ability to navigate through subfolders. I've figured out how to pin a folder onto the Start Menu in Windows 7, which required a registry hack. However, I am unable to view the subfolders of the pinned folder without opening a new Windows Explorer window. Is there any way to replicate the old XP behavior I'm used to? I'd like to be only a single click away from these handful of application links and folders, since I use them all the time throughout the day.

• How do I delete an Outlook calendar entry (after the meeting is over) without notifying the creator

  - by JabberwockyDecompiler

  I have several meetings during the day and I like to be able to open my calendar and see what is left at a glance so I delete the meetings that I have already completed. If I do this close enough to the meeting time I am asked if I want to notify the creator. If I do this after the meeting has started Outlook automatically sends a notice to the creator that I have declined the meeting. I am only deleting the one instance so it is still in my calendar for the next time, however that creates an email that others must read/delete. I need to be able to remove single occurrences of meetings without automatically sending a notice that I am deleting the entry. NOTE: I am using Outlook 2007, I did not see anything in the Advanced Email Options. NOTE 2: I have seen this happen with Lotus notes as well (Like anyone actually uses that). NOTE 3: There is not a sent message created, only the creator of the calendar event will see the message.

• GPU Computing - # of GPUs supported

  - by TehTypoKing

  I currently have a desktop with 6 GPUs ( 3x HD 5970s ) in non-crossfire mode. Unfortunately, it seems that Windows 7 64bit only supports up to 4 GPUs. I have not been able to find a reliable source to deny or confirm this. If windows 7 has this limitation, is there a Linux flavor that supports more than 4 GPUs? In-case you are wondering, this is not for gaming but high-speed single precision computing. With this current setup ( if I can find 6gpu support ) I am looking to reach 13.8 Teraflops. Also, my motherboard does support 3 16x pci-xpress gen2 slots... and I have a 1500w powersupply plugged into a 20amp outlet. Windows is able to detect all 6 cores.. although, 2 of which displays the warning "Drivers failed to load". To recap: - Can windows support 6 GPUs? - If not, does Linux? Thank you.
