  • Is there a very simple XML Editor/Viewer?

    - by Paul Spangle
    Part of our support job is to look at XML documents sent to our systems by our clients that have failed to load correctly. I do this by pasting the file in to Visual Studio as an XML file and VS colours it and adds line-breaks, indenting, etc. and it's then usually quite simple to spot the error and manually fix it and resubmit the document. Do I really have to use Visual Studio to do this? OK, it does the job quite well, but I'd have thought that something like Notepad++ would do the job just as well with a fraction of the machine resource usage. Is there are plugin for Notepad++ or another bit of freeware that can make XML look pretty and let me make simple edits?

  • Announcing the New Windows Azure Web Sites Shared Scaling Tier

    - by Clint Edmonson
    Windows Azure Web Sites has added a new pricing tier that will solve the #1 blocker for the web development community. The shared tier now supports custom domain names mapped to shared-instance web sites. This post will outline the plan changes and elaborate on how the new pricing model makes Windows Azure Web Sites an even richer option for web development shops of all sizes. Free Shared Reserved # of Sites 10 100 100 Egress 165MB/Day 5GB/Month Included 5GB/Month Included Storage 1GB 1GB 10GB Throttling CPU/Memory/Egress CPU/Memory Unlimited Price Free $.02/hr per site, per instance $.08/hr per core Setting the Stage In June, we released the first public preview of Windows Azure Web Sites, which gave web developers a great platform on which to get web sites running using their web development framework of choice. PHP, Node.js, classic ASP, and ASP.NET developers can all utilize the Windows Azure platform to create and launch their web sites. Likewise, these developers have a series of data storage options using Windows Azure SQL Databases, MySQL, or Windows Azure Storage. The Windows Azure Web Sites free offer enabled startups to get their site up and running on Windows Azure with a minimal investment, and with multiple deployment and continuous integration features such as Git, Team Foundation Services, FTP, and Web Deploy.  The response to the Windows Azure Web Sites offer has been overwhelmingly positive. Since the addition of the service on June 12th, tens of thousands of web sites have been deployed to Windows Azure and the volume of adoption is increasing every week. Preview Feedback In spite of the growth and success of the product, the community has had questions about features lacking in the free preview offer. The main question web developers asked regarding Windows Azure Web Sites relates to the lack of the free offer’s support for domain name mapping. During the preview launch period, customer feedback made it obvious that the lack of domain name mapping support was an area of concern. We’re happy to announce that this #1 request has been delivered as a feature of the new shared plan. New Shared Tier Portal Features In the screen shot below, the “Scale” tab in the portal shows the new tiers – Free, Shared, and Reserved – and gives the user the ability to quickly move any of their free web sites into the shared tier. With a single mouse-click, the user can move their site into the shared tier. Once a site has been moved into the shared tier, a new Manage Domains button appears in the bottom action bar of the Windows Azure Portal giving site owners the ability to manage their domain names for a shared site. This button brings up the domain-management dialog, which can be used to enter in a specific domain name that will be mapped to the Windows Azure Web Site. Shared Tier Benefits Startups and large web agencies will both benefit from this plan change. Here are a few examples of scenarios which fit the new pricing model: Startups no longer have to select the reserved plan to map domain names to their sites. Instead, they can use the free option to develop their sites and choose on a site-by-site basis which sites they elect to move into the shared plan, paying only for the sites that are finished and ready to be domain-mapped Agencies who manage dozens of sites will realize a lower cost of ownership over the long term by moving their sites into reserved mode. Once multi-site companies reach a certain price point in the shared tier, it is much more cost-effective to move sites to a reserved tier.  Long-term, it’s easy to see how the new Windows Azure Web Sites shared pricing tier makes Windows Azure Web Sites it a great choice for both startups and agency customers, as it enables rapid growth and upgrades while keeping the cost to a minimum. Large agencies will be able to have all of their sites in their own instances, and startups will have the capability to scale up to multiple-shared instances for minimal cost and eventually move to reserved instances without worrying about the need to incur continually additional costs. Customers can feel confident they have the power of the Microsoft Windows Azure brand and our world-class support, at prices competitive in the market. Plus, in addition to realizing the cost savings, they’ll have the whole family of Windows Azure features available. Continuous Deployment from GitHub and CodePlex Along with this new announcement are two other exciting new features. I’m proud to announce that web developers can now publish their web sites directly from CodePlex or GitHub.com repositories. Once connections are established between these services and your web sites, Windows Azure will automatically be notified every time a check-in occurs. This will then trigger Windows Azure to pull the source and compile/deploy the new version of your app to your web site automatically. Walk-through videos on how to perform these functions are below: Publishing to an Azure Web Site from CodePlex Publishing to an Azure Web Site from GitHub.com These changes, as well as the enhancements to the reserved plan model, make Windows Azure Web Sites a truly competitive hosting option. It’s never been easier or cheaper for a web developer to get up and running. Check out the free Windows Azure web site offering and see for yourself.

  • Efficient skeletal animation

    - by Will
    I am looking at adopting a skeletal animation format (as prompted here) for an RTS game. The individual representation of each model on-screen will be small but there will be lots of them! In skeletal animation e.g. MD5 files, each individual vertex can be attached to an arbitrary number of joints. How can you efficiently support this whilst doing the interpolation in GLSL? Or do engines do their animation on the CPU? Or do engines set arbitrary limits on maximum joints per vertex and invoke nop multiplies for those joints that don't use the maximum number? Are there games that use skeletal animation in an RTS-like setting thus proving that on integrated graphics cards I have nothing to worry about in going the bones route?

  • Thoughts of Cloud Development/Google App Engine

    - by jiewmeng
    I use mainly PHP for web development, but recently, I started thinking about using Google App Engine. It doesn't use PHP which I am already familiar with, so there will be a steeper learning curve. Probably using Python/Django. But I think it maybe worthwhile. Some advantages I see: Focus on App/Development. No need to setup/maintain server ... no more server configs Scales automatically Pay for what you use. Free for low usage Reliable, it's Google after all Some concerns though: Does database with no joins pose a problem for those who used App Engine before? Do I have to upload to Google just to test? Will it be slow compared to testing locally? What are your thoughts and opinions? Why would you use or not use App Engine?

  • No signal to monitor after driver install

    - by Hossam Riyad
    After installing 10.10 I used Hardware Drivers (Jockey) to install the graphics driver v11.2 for my ATI HD 5770. After restarting to activate the driver all went well and the boot screen showed up but not like the normal one the text was rough on the edges and after the boot finished the screen turned black and no signal. I have found some forum discussions about that issue but no fix worked for me. I use a DVI to VGA adapter and I have a View Sonic E70F CRT monitor.

  • Linux installation on Acer Aspire One D270

    - by ronnie
    I was planning to buy Acer Aspire One D270 within a few days and as everybody installs linux on their netbook I was also planning to do that. Now, my question is how is Acer's hardware compatibility with linux and specifically in respect to the new Acer Aspire One D270. Has anybody tried installing linux on these new netbooks. It will be a great help if a D270 user can share his/her experience with linux usage. I read on some forums that there is some linux driver issue with Intel GMA 3600 and that people are not able to adjust their brightness. So, as I am a linux noob is this a major issue or not.

  • Ubuntu Slows down over time?

    - by Lucas McCoy
    About a few months ago I was using Ubuntu (doing something in the command line) when it started lagging really bad. I would hit S (or any other key) and like 20 seconds later it would show up in my terminal. Naturally I killed the machine and rebooted. The system started working just fine, but about 30 minutes later it did the same thing. Now I'm forced to use Ubuntu in 30 minute spurts. I've looked at my running processes and none of them are taking large amounts of CPU or RAM. Luckily I've dual-booted so I could still use my machine. Now I need to get this fixed and I'm wondering what my options are. Will I be forced to do a fresh install or is there another way?

  • How to check the information of current installed video drivers on Ubuntu?

    - by smwikipedia
    Hi guys, I have just installed Ubuntu 10.04. My CPU usage is high when I do trivial things such as scrolling through a PDF file. So I think my video driver is not properly installed. I want to confirm that by checking the information of my currently installed video driver, such as if there's a driver installed and what version it is. Then I could decide whether to install a new one if it is not up to date. On Windows, I could use the device manager, how to do that on Ubuntu Linux? I don't expect a GUI solution for this. Command line will be just good enough. Many thanks.

  • How to Install & Use the Window Maker Desktop Environment on Ubuntu

    - by Chris Hoffman
    Window Maker is a Linux desktop environment designed to emulate NeXTSTEP, which eventually evolved into Mac OS X. With its focus on emulating NeXTSTEP, it eschews the task bars and application menu buttons found in many other lightweight desktop environments. Window Maker is now under active development again after seven years without an official release. A lot has changed on the Linux desktop front since Window Maker was last being actively developed, but Window Maker still provides a unique, minimal environment – for users looking for that sort of thing.

  • Cool a Computer with Toilet Water

    - by Jason Fitzpatrick
    When most people opt to use water cooling they put together tidy coolant reservoirs complete with ambient lighting and the like. This build involves a hole in the wall and the tank of a functioning toilet. The design, courtesy of Jeff Gagnon, is unconventional, but effective. Opposite of his wall-mounted PC is a bathroom. In that bathroom he has a coolant pump in the tank of the toilet. Using the toilet tank as a thermal sink he keeps the CPU at a nice chilly 66F. Hit up the link below for more pictures, including a peek inside his hacked together toilet-tank cooling rig.

  • PASS Summit 2011 &ndash; Part III

    - by Tara Kizer
    Well we’re about a month past PASS Summit 2011, and yet I haven’t finished blogging my notes! Between work and home life, I haven’t been able to come up for air in a bit.  Now on to my notes… On Thursday of the PASS Summit 2011, I attended Klaus Aschenbrenner’s (blog|twitter) “Advanced SQL Server 2008 Troubleshooting”, Joe Webb’s (blog|twitter) “SQL Server Locking & Blocking Made Simple”, Kalen Delaney’s (blog|twitter) “What Happened? Exploring the Plan Cache”, and Paul Randal’s (blog|twitter) “More DBA Mythbusters”.  I think my head grew two times in size from the Thursday sessions.  Just WOW! I took a ton of notes in Klaus' session.  He took a deep dive into how to troubleshoot performance problems.  Here is how he goes about solving a performance problem: Start by checking the wait stats DMV System health Memory issues I/O issues I normally start with blocking and then hit the wait stats.  Here’s the wait stat query (Paul Randal’s) that I use when working on a performance problem.  He highlighted a few waits to be aware of such as WRITELOG (indicates IO subsystem problem), SOS_SCHEDULER_YIELD (indicates CPU problem), and PAGEIOLATCH_XX (indicates an IO subsystem problem or a buffer pool problem).  Regarding memory issues, Klaus recommended that as a bare minimum, one should set the “max server memory (MB)” in sp_configure to 2GB or 10% reserved for the OS (whichever comes first).  This is just a starting point though! Regarding I/O issues, Klaus talked about disk partition alignment, which can improve SQL I/O performance by up to 100%.  You should use 64kb for NTFS cluster, and it’s automatic in Windows 2008 R2. Joe’s locking and blocking presentation was a good session to really clear up the fog in my mind about locking.  One takeaway that I had no idea could be done was that you can set a timeout in T-SQL code view LOCK_TIMEOUT.  If you do this via the application, you should trap error 1222. Kalen’s session went into execution plans.  The minimum size of a plan is 24k.  This adds up fast especially if you have a lot of plans that don’t get reused much.  You can use sys.dm_exec_cached_plans to check how often a plan is being reused by checking the usecounts column.  She said that we can use DBCC FLUSHPROCINDB to clear out the stored procedure cache for a specific database.  I didn’t know we had this available, so this was great to hear.  This will be less intrusive when an emergency comes up where I’ve needed to run DBCC FREEPROCCACHE. Kalen said one should enable “optimize for ad hoc workloads” if you have an adhoc loc.  This stores only a 300-byte stub of the first plan, and if it gets run again, it’ll store the whole thing.  This helps with plan cache bloat.  I have a lot of systems that use prepared statements, and Kalen says we simulate those calls by using sp_executesql.  Cool! Paul did a series of posts last year to debunk various myths and misconceptions around SQL Server.  He continues to debunk things via “DBA Mythbusters”.  You can get a PDF of a bunch of these here.  One of the myths he went over is the number of tempdb data files that you should have.  Back in 2000, the recommendation was to have as many tempdb data files as there are CPU cores on your server.  This no longer holds true due to the numerous cores we have on our servers.  Paul says you should start out with 1/4 to 1/2 the number of cores and work your way up from there.  BUT!  Paul likes what Bob Ward (twitter) says on this topic: 8 or less cores –> set number of files equal to the number of cores Greater than 8 cores –> start with 8 files and increase in blocks of 4 One common myth out there is to set your MAXDOP to 1 for an OLTP workload with high CXPACKET waits.  Instead of that, dig deeper first.  Look for missing indexes, out-of-date statistics, increase the “cost threshold for parallelism” setting, and perhaps set MAXDOP at the query level.  Paul stressed that you should not plan a backup strategy but instead plan a restore strategy.  What are your recoverability requirements?  Once you know that, now plan out your backups. As Paul always does, he talked about DBCC CHECKDB.  He said how fabulous it is.  I didn’t want to interrupt the presentation, so after his session had ended, I asked Paul about the need to run DBCC CHECKDB on your mirror systems.  You could have data corruption occur at the mirror and not at the principal server.  If you aren’t checking for data corruption on your mirror systems, you could be failing over to a corrupt database in the case of a disaster or even a planned failover.  You can’t run DBCC CHECKDB against the mirrored database, but you can run it against a snapshot off the mirrored database.

  • A Method for Reducing Contention and Overhead in Worker Queues for Multithreaded Java Applications

    - by Janice J. Heiss
    A java.net article, rich in practical resources, by IBM India Labs’ Sathiskumar Palaniappan, Kavitha Varadarajan, and Jayashree Viswanathan, explores the challenge of writing code in a way that that effectively makes use of the resources of modern multicore processors and multiprocessor servers.As the article states: “Many server applications, such as Web servers, application servers, database servers, file servers, and mail servers, maintain worker queues and thread pools to handle large numbers of short tasks that arrive from remote sources. In general, a ‘worker queue’ holds all the short tasks that need to be executed, and the threads in the thread pool retrieve the tasks from the worker queue and complete the tasks. Since multiple threads act on the worker queue, adding tasks to and deleting tasks from the worker queue needs to be synchronized, which introduces contention in the worker queue.” The article goes on to explain ways that developers can reduce contention by maintaining one queue per thread. It also demonstrates a work-stealing technique that helps in effectively utilizing the CPU in multicore systems. Read the rest of the article here.

  • Juju didn't configure rabbitmq for openstack?

    - by SaM
    I have installed ubuntu Openstack HA with juju with all 24 servers. But my openstack is not working at all. On dashboard on every page I get errors saying "could not retrieve usage information", "could not retrieve volume information, "could not retrieve .....etc I spent hours and have discovered that juju has not done configuration correctly. I found that on cloud controller in nova.conf juju has added rabitmq vhost enrty, but that virtual host is not added in rabbitmq. Then how is its suppose to work? And on juju-gui canvas rabbimq is all green and is working fine, which in reality its not. I am really wondering if juju has really done correct configuration in all 24 servers now, I am getting the feeling that it would have been faster if I would have done openstack deployment manually instead of using juju. Why was the virtual host entry not added in rabbitmq? How should I solve this?

  • How do I get Flash 10.2 RC + Crystal HD for HW accelerated video to work?

    - by Gee
    I have a netbook with a N450 Atom and a BCM70012 aka Crystal HD card. On Windows 7 I can play HD flash video with very little CPU usage because of the RC of Flash 10.2. I did some reading and saw posts claiming that the Crystal HD card is finally supported by the newer Flash 10.2 RC in Ubuntu but I can't get it to work. I can confirm that flash 10.2 is loaded and used, and there's even a HW acceleration option that is enabled in the settings but performance is horrible. From what I read, the Crystal HD card is supposed to be enabled on 10.10 by default - I don't know if it is. I tried installing drivers for it in various ways but HD flash video is still a slideshow So does anyone have it working? If so, how'd you set it up?

  • Building small Ubuntu server - What hardware is recommended?

    - by 10robinho
    There are many of us who need to build small Ubuntu server. Problem is that in some countries it is hard to find and quite expensive to buy server motherboards and processors. And when one is building small server with limited budget, buying some Xenons is not really an option. So, are there any general recommendations for hardware (I think that motherboards are the main issue) that is stable and fast under Linux? I read that Intel should be the best choice for cpu + mbo combo. So, I was looking around for some Intel motherboards + i7 Ivy Bridge (like Intel DZ77BH-55K with Z77 chipset and Intel i7 3770K) but I've read that they have some issues with kernel, booting and USB ports. That is why I ask community if you have any experience with this. Maybe Intel is not the best choice here? Maybe ASUS or Gigabyte or _other company_ are more stable with Linux? I hope that this Q&As can help people in building stable Ubuntu server.
