• Xen and Ubuntu?

  - by wag2639

  How does one properly approach having Ubuntu servers on a Xen hypervisor? I don't have any experience with RAID or Xen other than from a theoretical level. Additional requirements: Use with mdadm Software RAID 5 (can be on separate disks) that multiple instances with access Paravirtualized Ubuntu Server guests instances Possible ideas for now: Ubuntu host (dom0) with ubuntu-xen-server package (this purportedly isn't supported) dom0 host will "own" RAID 5 partition More Ubuntu servers as guests Citrix XenServer bare-metal host XenServer will own RAID Citrix XenServer bare-metal host Ubuntu guest instance creates and owns RAID Questions and concerns: Can Ubuntu be used as a dom0 Xen host? Can XenServer install packages such as mdadm and create a partition? Can multiple guest access (R + W) to the same data partition (RAID)? Note: since it may have a bearing on support, I'm referring to Ubuntu Server 10.04

• uTorrent error: Access is denied

  - by Ben Franchuk

  When I booted my computer today and opened up uTorrent it went on, as usual, to check the torrents that I had been running before. On one it returned an "Access is denied" error after it had been checked. I have absolutely no idea why this is happening as I was downloading the same torrent just the night before, and additionally because I have other torrents going in the same downloads folder and they do not have any such errors. It may be worth noting that on said defective torrent, there appear to be no seeds and no connected peers (of the 33 available) and three of the trackers appear to be inactive as well (those being Peer Exchange, Local Peer Discovery and DHT). I have rebooted a few times in an attempt to fix this problem, but to no success. I also tried a few times force rechecking / force starting but neither of those worked either. edit I booted today and it was working for whatever reason. thanks for all of the help anyways guys!

• Install Base Transaction Error Troubleshooting

  - by LuciaC

  Oracle Installed Base is an item instance life cycle tracking application that facilitates enterprise-wide life cycle item management and tracking capability.In a typical process flow a sales order is created and shipped, this updates Inventory and creates a new item instance in Install Base (IB).  The Inventory update results in a record being placed in the SFM Event Queue.  If the record is successfully processed the IB tables are updated, if there is an error the record is placed in the csi_txn_errors table and the error needs to be resolved so that the IB instance can be created.It's extremely important to be proactive and monitor IB Transaction Errors regularly.  Errors cascade and can build up exponentially if not resolved. Due to this cascade effect, error records need to be considered as a whole and not individually; the root cause of any error needs to be resolved first and this may result in the subsequent errors resolving themselves. Install Base Transaction Error Diagnostic Program In the past the IBtxnerr.sql script was used to diagnose transaction errors, this is now replaced by an enhanced concurrent program version of the script. See the following note for details of how to download, install and run the concurrent program as well as details of how to interpret the results: Doc ID 1501025.1 - Install Base Transaction Error Diagnostic Program  The program provides comprehensive information about the errors found as well as links to known knowledge articles which can help to resolve the specific error. Troubleshooting Watch the replay of the 'EBS CRM: 11i and R12 Transaction Error Troubleshooting - an Overview' webcast or download the presentation PDF (go to Doc ID 1455786.1 and click on 'Archived 2011' tab).  The webcast and PDF include more information, including SQL statements that you can use to identify errors and their sources as well as recommended setup and troubleshooting tips.

• Sharding / indexing strategy for multi-faceted search

  - by Graham

  I'm currently thinking about our database structure and how we modify it for scale. Specifically, we're thinking about using ElasticSearch to provide our search functionality. One common pattern with ElasticSearch seems to be the 'user-routing' pattern; that is, using routing to ensure that any one user's data resides on the same shard. This is great for client-specific search e.g. Gmail. Our application has a constraint such that any user will have a maximum of a few thousand documents, so this pattern seems like a good candidate. However, our search needs to work across all users, as well as targeting a specific user (so I might search my content, Alice's content, or all content). Similarly, we need to provide full-text search across any timeframe; recent months to several years ago. I'm thinking of combining the 'user-routing' and 'index-per-time-interval' patterns: I create an index for each month By default, searches are aliased against the most recent X months If no results are found, we can search against previous X months As we grow, we can reduce the interval X Each document is routed by the user ID So, this should let us do the following: search by user. This will search all indeces across 1 shard search by time. This will search ~2 indeces (by default) across all shards Is this a reasonable approach, considering we may scale to multi-million+ documents? Or should I be denormalizing the data somehow, so that user searches are performed on a totally seperate index from date searches? Thanks for any pros-cons of the above scenario.

• Volume randomly turning itself down on Windows 7 64-bit

  - by Arda Xi

  This is the weirdest issue I've ever encountered with my PC. Every so often, my sound will start playing back at a lower volume. This happens when watching video, listening to music, all independently. It usually lasts anywhere up to a minute, after which it will turn up again. The weird thing about it is that the volume control in Windows remains at 100%, even though the volume is audibly a lot lower. (No, I'm not going deaf, it's just my PC. I checked.) I just have no idea where to go to troubleshoot this, even. I'm using Windows 7 64-bit with an on-board Realtek sound-card. Oh, just in case someone finds this question on Google or whatever, making sure this is on Do Nothing may fix your problem. Unfortunately, it did not work for me. My settings all seem fine. This is my audio slider. (Took the screenshot while the issue showed.)

• I have to manually enter the pwd when I login at school and when I come back home with my laptop (DELL E6410)

  - by Bong Paduano

  I didn't have to do this the first 3 months of me going to school. My laptop used to be able to connect to my Home WiFi and school Wifi automatically then after the 3rd month something changed and eversince then I literally have to manually enter each of the Wifi passwords in each location each time I try to connect to their respective WLAN. I tried adding each WiFi networks in the "Manage wireless networks" section in the Network and Sharing Center but everytime I login to one of the location, the created network disappears and I did this more than once. I tried restoring the OS back but to no avail. Can someone please assist me on this issue. I'm not sure if this issue has been addressed in this website but I haven't seen any similar question in here. I appreciate any help anyone may be able to share.

• showing hiding toolbars with shortcuts in firefox

  - by Edwinistrator

  I'm a webdeveloper and using firefox with the bookmarks toolbar, the webdeveloper toolbar and the google toolbar. Are there shortcuts in firefox 3.5 to hide and show these toolbars. If not, may be an add on wich works in 3.5 to create a small script to hide these toolbars, bind with a shortcut? I found keyconfig addon but won't work in 3.5.

• ASP.NET MVC 3 (C#) Software Architecture

  - by ryanzec

  I am starting on a relatively large and ambitious ASP.NET MVC 3 project and just thinking about the best way to organize my code. The project is basically going to be a general management system that will be capable of supporting any type management system whether it be a blogging system, cms, reservation system, wikis, forums, project management system, etc…, each of them being just a separate 'module'. You can read more about it on my blog posted here : http://www.ryanzec.com/index.php/blog/details/8 (forgive me, the style of the site kinda sucks). For those who don't want to read the long blog post the basic idea is that the core system itself is nothing more than a users system with an admin interface to manage the users system. Then you just add on module as you need them and the module I will be creating is a simple blog post to test it out before I move on to the big module which is a project management system. Now I am just trying to think of the best way to structure this so that it is easy for users to add in there own modules but easy for me to update to core system without worrying about the user modifying the core code. I think the ideal way would be to have a number of core projects that user is specifically told not to modify otherwise the system may become unstable and future updates would not work. When the user wants to add in there own modules, they would just add in a new project (or multiple projects). The thing is I am not sure that it is even possible to use multiple projects all with their own controllers, razor view template, css, javascript, etc... in one web application. Ideally each module would have some of it own razor view templates, css, javascript, image files and also need access to some of the core razor view templates, css, javascript, image files which would is in a separate project. It is possible to have 1 web application run off of controllers, razor view templates, css, javascript, image files that are store in multiple projects? Is there a better was to structure this to allow the user to easily add in module with having to modify the core code?

• In the Aggregate: How Will We Maintain Legacy Systems? [closed]

  - by Jim G.

  NEW YORK - With a blast that made skyscrapers tremble, an 83-year-old steam pipe sent a powerful message that the miles of tubes, wires and iron beneath New York and other U.S. cities are getting older and could become dangerously unstable. July 2007 Story About a Burst Steam Pipe in Manhattan We've heard about software rot and technical debt. And we've heard from the likes of: "Uncle Bob" Martin - Who warned us about "the consequences of making a mess". Michael C. Feathers - Who gave us guidance for 'Working Effectively With Legacy Code'. So certainly the software engineering community is aware of these issues. But I feel like our aggregate society does not appreciate how these issues can plague working systems and applications. As Steve McConnell notes: ...Unlike financial debt, technical debt is much less visible, and so people have an easier time ignoring it. If this is true, and I believe that it is, then I fear that governments and businesses may defer regular maintenance and fortification against hackers until it is too late. [Much like NYC and the steam pipes.] My Question: Is there a way that we can avoid the software equivalent of NYC and the steam pipes?

• GeForce and Radeon: what is present condition of opensource and proprietary drivers?

  - by Septagram

  So, it'm about to buy a fresh videocard. Since I do most of my stuff on Linux, I wonder how well will either videocard perform. I recently had a good experience with GeForce 6600 with proprietary drivers and a less than satisfactory experience with Radeon 9000 a while ago. From my experience, proprietary drivers for GeForce used to work very well, while proprietary drivers for Radeon failed miserably. And opensource drivers were sloooow. A few months ago I found out that ATI opened their specifications, and a work on fully featured opensource driver is in progress. I prefer to use free software whenever possible, with the exception of games, so, if that driver is fast enough, feature-rich enough and reliable enough I'd very much like to try it out. I wish I could say that if I can just to basic things, like watch video, heavily use compiz and work with simple applications, this may be enough. I do most of my gaming under Windows anyway. However, there is a good chance I'll go into indie game development in a few months fulltime, so it should also be able to run not-so-very-demanding games (say Nexuiz). But if it isn't, I'd like to know, what to expect from proprietary drivers. Do recent proprietary drivers from NVIDIA and ATI work well? Are ATI drivers just as easy to install on Ubuntu as are NVIDIA drivers?

• How do sites avoid SEO issues / legalities with subdomain unique ids?

  - by JM4

  I was looking through a few websites recently and noticed a trend I'm not sure I understand. Sites are creating unique referral URLs for customers in the form of: http://customname.site.com (If somebody were to use http://www.site.com/customname it would function the same way). I can see the sites are using 302 redirects at some point using Google Chrome then doing some sort of htaccess redirect, taking the subdomain name (customname) and applying it as a referral parameter then keeping in session during the entire process. However, there must be thousands of these custom URLs that people are typing in. How are each one of these "subdomains" not treated as separate URLs which in turn are redirected to the same page (in short, generating tons of links all pointing to the same page which Google would normally frown upon)? Additionally, the links also appear on the site themselves as clickable links so I'm not sure how these are not tracked. Similarly, the "unique" url is not indexed or cached in any Google search results. How is this capability handled? It does NOT highlight the referral aspect, but a true example of this is visiting http://sfgiants.com which does a 302 redirect to the much longer proper San Francisco Giants MLB homepage. I am wondering how SFgiants.com is not indexed (assuming that direct shortened link appears on several MLB pages)? 1 - I know these are 302 redirects, I can see this on the sites network flow. 2 - These links do in fact appear on the page itself because in some areas (for example, the bottom of the page may say: send this page to a friend! http://name.site.com/ which in turn would again redirect to something like http://www.site.com?id=name so the id value could be stored in session

• Intermittent freezing on a Macbook Pro 7,1

  - by LR0

  I recently installed Ubuntu 12.10 on my MacBook Pro 7, 1. I used to have 11.10 on it. I've encountered a problem were I can boot up and the login screen works flawlessly. When I attempt to log into my account I set up during install it would only show the default wallpaper and the mouse was frozen. In other words it was logging on but froze up. Is what it seems like. When I rebooted I attempted to log into the guest account. I was able to log in and it seemed everything worked so I tried to update everything figuring it may be the problem. After updating and restarting as prompted I tried to login to my account. It still froze up but this time showing "glitched up" (you can see the dock and status bar but they don't look like they should) and still freezes. This is all happening on the guest account to. I was unable to find a similar article on the Internet therefore I am asking; Any thoughts Ubuntu?

• Plesk 9.2.1 reporting much more SMTP traffic than the logs indicate

  - by Eric3

  Plesk is reporting nearly 7GB of SMTP traffic so far this month on one domain, most of it outgoing. However, after running qmail's mail logs (which only go back to May 8) through Sawmill, only about 900MB of traffic on that domain is accounted for. What I know so far: Email sent via PHP's mail() function is sent through sendmail, which has been logging its output via syslog to the same logs that qmail uses, at /usr/local/psa/var/log/ Messages sent by logging in directly via Telnet are logged as well I verified that Plesk is reporting totals correctly by creating a new domain, sending some large emails through it, running Plesk's statistics calculation script, and comparing its reported totals to the actual size of the emails sent The problem domain did have three mail accounts with blank or insecure passwords, which I corrected Does anyone know how Plesk calculates SMTP traffic statistics? Are there some log files elsewhere that I'm missing? What kind of SMTP traffic would Plesk know about that isn't being logged?

• How to target just one search engine and optimise for that

  - by mickburkejnr

  I've been dabbling with SEO a lot in the last 6 months, and one thing that has surprised me is the disparity between Google and Bing in the way they deliver results. A website ranked for a specific keyword/phrase on Google may rank 3rd on the first page, but using the same keyword/phrase on Bing will display the same website but ranked 15th for the exact same keyword/phrase. I came up with the idea to increase traffic to my website by targetting Bing instead of Google for several reasons. The biggest one is that while it's not the biggest search provider, people still use it, and I feel that if other websites have been "neglected" and not optimised for Bing my website would stand a better chance of getting near the top of their search rankings. The question is though how would I do this? A lot of the SEO advice on the internet is generic, but I can't help feeling it's Google orientated for obvious reasons. How could I optimise my website to be Bing friendly, rather than Google friendly? I know it sounds like suicide as I'm taking myself out of the Google mindset, but I feel it could work wonders for traffic to the site.

Is it possible for me to link the folders /opt/software/data with /hdd2/software/data so, that every file get stored in the /hdd2/software/data but may be referred from the /opt/software/data? I can't do a reinstall of the software that creates this data, to change the default location of storage.

• Have Windows Automatically Login Without Entering Your Password

  - by deadlydog

  If you are like me and don't want to have to enter your password each time Windows loads, you can have Windows start up without prompting you to enter a user name or password.  The simple (and BAD) way to do this is to simply not have a password on your user account, but that’s a big security risk and will allow people to easily remote desktop into your computer. So, first set a password on your windows account if you don’t already have one.  Then select Run... from the start menu (or use Windows Key + R to open the Run window) and type control userpasswords2, which will open the user accounts application.   On the Users tab, clear the box for Users must enter a user name and password to use this computer, and click on OK. An Automatically Log On dialog box will appear; enter the user name and password for the account you want to use to automatically log into Windows.  That's it.    You may also want to make sure your screen saver is not set to prompt you for a password when it exits either. Now your computer is secure without getting in your way.

• Triple-display setup using AMD drivers

  - by Halik

  I am currently running a dual display setup with nVidia 8800GTS video card, on a Ubuntu 12.10 box. The current setup uses nVidia TwinView to render the image on a 1920x1200 display and 1600x1200 one. I'm planning to add a third, 1280x1024 display to the setup. The change will require me to upgrade my GFX card to one supporting triple displays. I'll probably go with Sapphire Radeon 7770 (FLEX edition, to avoid additional active DP-DVI adapters). Before I invest in new GFX I wanted to ask - how well the AMD drivers will support such a setup. It does not matter whether it's fglrx or the OSS ones. If I remember correctly, when running Fedora on a Radeon x800, I had 'void' areas above and below the working area on my second display. The desktop was rendered in 1920+1280 width and 1200 height (which left 176px of vertical space accessible for my cursor and windows but not displayed on the screen - I'd prefer to avoid that). It may have very well been my misconfiguration back then. Generally, are there any solutions from AMD on par with TwinView? Or is it a non-issue at all? Also, I'm wondering about the usual stuff - hardware h264 decoding support, glitch-free flash support, any issues with Compiz/Unity?

• SEO and external sites that serve responsive images (like Re-SRC)

  - by Baumr

  Re-SRC is a tool that allows you to automatically serve responsive images for your website from their cloud servers. It delivers a new image file each time the browser window (viewport) is resized. To use it in your HTML when linking to an image, you would do the following: <img src="http://app.resrc.it//www.your-domain.com/img/img001.jpg"/> Some more background for SEO considerations: As an example, looking at their demo page's code, the src of the Arc de Triomphe photo — when the browser window is resized to be at a tablet-width — shows this particular file at it's widest. It is found under the following URL: http://app4-uk.resrc.it/s=w560,pd1/ro=h//www.resrc.it/img/demo/demo-image-1.jpg If the viewport is increased to desktop-width, then a smaller image is served in line with the design; see this URL: http://app4-uk.resrc.it/s=w320,pd1/ro=h//www.resrc.it/img/demo/demo-image-1.jpg If I change the viewport to be about half-way between those two, then the image's URL is: http://app4-uk.resrc.it/s=w240,pd1/ro=h//www.resrc.it/img/demo/demo-image-1.jpg In other words, I found that there is a separate file for every 10-pixel increment of the image width. Very cool for saving bandwidth on mobile devices and service responsive/retina images on others, but... Here are two problems I see for SEO: The img on your site, part of your semantic markup, will not be hosted on your site at all, or even a server you control. Any links to these images will pass on "link juice" to Re-SRC's site instead. You are serving a vast array of different image files to different people — some may link to one, others to another size. Then there's the question of what different search engine crawlers will see. Also: There seems to be no fallback option if their servers are down. Do you see any other concerns? Or, perhaps, do you not see those as concerns?

• recent unreliable wireless connection

  - by gabkdlly

  Recently, my internet connection over wireless ( via a Netgear KWGR614 router ) has become unreliable, on both a Dell laptop running Ubuntu 10.04 as well as my Desktop running Ubuntu 10.10 . The problem does not seem to occur on a laptop running Windows Vista, nor on a Desktop running Windows 7 ( this machine is connected with an ethernet cable ). The problem does not seem to occur on my Openmoko Freerunner ( running Android 1.5 ), though I hardly ever use this device to connect over WLAN, so the problem may have just slipped by. On my main Ubuntu Desktop, I have tried the following wireless devices: a Longshine PCI card ( an old device with an RTL8180L chip ) a D-Link DWL-510 PCI card ( this device threw warnings in dmesg ) a USB device from MSI ( US54EX ). Usually my wireless network shows up in the network manager with a normal signal strength, even when the connection speed is slow or the connection gets reset ( asking me to click connect to re-authenticate my wireless connection ). I have observed this problem with a Netgear KWGR614 Router ( with the manufacturers firmware ), as well as with a TP-LINK TL-WR741ND router running OpenWrt. Taking a look at my routers logs, I find many instances of the following line: Tuesday,04 Jan 2011 03:53:01 [TCP SYN Flood][Deny access policy matched, dropping packet] I know that the Netgear router is susceptible to denial of service attacks, as I have previously been able to disrupt its operation by putting an nmap scan into a while loop. I use WEP or WPA to encrypt the wireless network. Is it possible that someone is jamming my signal ?

• Recent Hotmail Update is crashing FireFox. Is there a fix available

  - by hcabnettek

  I have latest version of FireFox. It has always worked fine using HOTMAIL until recently. I check a checkbox on my items list and FireFox chokes. Thinking back it seems to have started after a recent FireBug update so that may be related. I am liking the older version of Firebug better by the way but thats another post alltogether. Is anyone else having this problem? Is there a fix available? Thanks, ~ck in San Diego
