  • PASS Summit for SQL Starters

    - by Davide Mauri
    I’ve received a buch of emails from PASS Summit “First Timers” that are also somehow new to SQL Server (for “somehow” I mean people with less than 6 month experience but with some basic knowledge of SQL Server engine) or are catching up from SQL Server 2000. The common question regards the session one should not miss to have a broad view of the entire SQL Server platform have some insight into some specific areas of SQL Server Given that I’m on (semi-)vacantion and that I have more free time (not true, I have to prepare slides & demos for several conferences, PASS Summit  - Building the Agile Data Warehouse with SQL Server 2012 - and PASS 24H - Agile Data Warehousing with SQL Server 2012 - among them…but let’s pretend it to be true), I’ve decided to make a post to answer to this common questions. Of course this is my personal point of view and given the fact that the number and quality of session that will be delivered at PASS Summit is so high that is very difficoult to make a choice, fell free to jump into the discussion and leave your feedback or – even better – answer with another post. I’m sure it will be very helpful to all the SQL Server beginners out there. I’ve imposed to myself to choose 6 session at maximum for each Track. Why 6? Because it’s the maximum number of session you can follow in one day, and given that all the session will be on the Summit DVD, they are the answer to the following question: “If I have one day to spend in training, which session I should watch?”. Of course a Summit is not like a Course so a lot of very basics concept of well-established technologies won’t be found here. Analysis Services, Integration Services, MDX are not part of the Summit this time (at least for the basic part of them). Enough with that, let’s start with the session list ideal to have a good Overview of all the SQL Server Platform: Geospatial Data Types in SQL Server 2012 Inside Unstructured Data: SQL Server 2012 FileTable and Semantic Search XQuery and XML in SQL Server: Common Problems and Best Practice Solutions Microsoft's Big Play for Big Data Dashboards: When to Choose Which MSBI Tool Microsoft BI End-User Tools 360° for what concern Database Development, I recommend the following sessions Understanding Transaction Isolation Levels What to Look for in Execution Plans Improve Query Performance by Fixing Bad Parameter Sniffing A Window into Your Data: Using SQL Window Functions Practical Uses and Optimization of New T-SQL Features in SQL Server 2012 Taking MERGE Beyond the Basics For Business Intelligence Information Delivery Analyzing SSAS Data with Excel Building Compelling Power View Reports Managed Self-Service BI PowerPivot 101  SharePoint for Business Intelligence The Best Microsoft BI Tools You've Never Heard Of and for Business Intelligence Architecture & Development BI Power Hour Building a Tabular Model Database Enterprise Information Management: Bringing Together SSIS, DQS, and MDS SSIS Design Patterns Storing Columnstore Indexes Hadoop and Its Ecosystem Components in Action Beside the listed sessions, First Timers should also take a look the the page PASS set up for them: http://www.sqlpass.org/summit/2012/Connect/FirstTimers.aspx See you at PASS Summit!

  • Launcher tooltip display issues

    - by Tudor
    I've just installed Ubuntu 12.04.1, and it seems that i have some issues with the launcher: if i hover the mouse on an icon, it shows an horizontal line instead of the icon's name. if i hover it again, then it will show me the correctly displayed name, in label and all. The thing is pretty annoying. First hover no label (just that line), second hover, label. Video drivers are installed ! Any thoughts? Thank you

  • Free web "caching" services for a web service

    - by Jason Banico
    I have a web service on Google App engine whose data is updated on a daily basis. To minimize bandwidth utilization from mobile clients connecting to it, I'd like to instead have an intermediary site where the clients will be getting their data from, and minimizing hits to my service to once or twice a day only. Is there such a service I can use? I'd like to explore this "pull" option first, before considering "push" options such as publishing to a blog site or a free website host that doesn't have bandwidth caps.

  • Kworker, what is it and why is it hogging so much CPU?

    - by davorao
    I recently upgraded to the Kubuntu Natty Beta 1 and I've been having a lot of issues with the process kworker. At moments it uses almost half my CPU. Also, strangely enough it seems to affect my USB ports; whenever I plug in an USB drive, the process kworker goes into hyperdrive, leaving me unable to work. I have thought about filing a bug but since I haven't even found any reasonable explanation on what kworker is I figured I should find out first.

  • Display artifacts under Ubuntu 12.10

    - by James McMahon
    I am getting some display artifacts under a fresh install of 12.10. (Open image in an another tab to get the full effect) Anyone have any idea what might be going on here or a possible solution? My first assumption was display driver, but I've been have some difficulties getting the Nvidia binary driver to work. So I wanted to check for other possible solutions before I spend a lot of time messing with getting that to work.

  • Determining cause of random latency/loading issues

    - by Sherwin Flight
    I'm not sure exactly what details to post in regards to my issue, because I'm not sure what is relevant. Prior to the end of September my websites all loaded quickly, in almost all cases. Loading time wasn't usually more than a few seconds. However, since the end of September I noticed a big increase in page loading times. In some cases pages were taking 30 seconds or more to load. I do have a remote monitoring service monitoring some of the sites as well, and the image below shows the response times over the past month. The response times shown at the beginning of this graph were what the usual response times were prior to this issue occurring. You can see that there has been a significant increase in response times from the beginning to the end of this graph. The thing is, the problem is not happening 100% of the time. If I click through the site, or even just keep refreshing the page, about 25% of the time the pages load quickly, the remaining 75% of the time they load slowly. Sometimes the pages take so long to load that they time out, and don't load at all. I have contacted my hosting provider, and they said things at their end was fine. I don't believe the problem is my home internet provider, because all other websites load without a problem. The server is located in Texas, USA. This also raises another interesting point. My remote monitor checks my site from two locations, California, USA, and London, England. As you can see in the chart below the response time is actually shorter when checked from London, which doesn't seem to make sense, since the server is physically closer to the California monitoring location. I would have expected the London monitoring location to have higher response times since they are physically farther away. I should also point out that in some traceroute test I've done it seem like the first connection to the server seems to take the longest, then after that the rest of the page loads quickly. Below is a little chart showing the times for the first connection to the server. So, what could be causing this problem, and what steps can I take to resolve it or at least narrow down the problem? Sending the request to the server was very quick, and receiving the reply back seems pretty quick, but the WAIT time is really long. So it connects, sends the request, but then waits close to 30 seconds before it starts receiving data back. I am also aware that there are things I can do to speed up page loading times, like reducing the number of css/js files used on a page, compressing images, etc. This is not really what the source of the problem is though, because nothing has really changed on the site since before the problem started, and other sites on the same server are loading slowly as well. Any help or advice is much appreciated.

  • What non-programming books should a programmer read to help develop programming/thinking skills?

    - by FeatureCreep
    There are a lot of questions about what programming books should be on the programmer's bookshelf. How about non-programming related books that can help you become a better programmer or developer? It would also be interesting to know why they would help. My first choice would be Sun Tzu's "Art of War" (however cliché), because it made it obvious that the success of any project depends on the strength of its weakest link (and warfare is a big project).

  • How to Build a Website

    I am an affiliate marketer. So when I first build a website, I will build it around a topic and not around the product. I'll take the primary keyword and make that my domain name. I do this so that my website will rank well in the search engines. Then I go about selecting categories from the next keyword phrases down.

  • How to specify expiration of cacheable resources?

    - by Richard
    I'm trying to speed up a wordpress site -- this site: http://richardclunan.net I'm following the observations here: http://gtmetrix.com/reports/richardclunan.net/9ps7Zc0j The first item says: "The following cacheable resources have a short freshness lifetime. Specify an expiration at least one week in the future for the following resources:" How do I specify expirations for those things? (I'm not very technically-minded, and likely won't know relevant terminology -- really appreciate baby-steps explanation if possible :)

  • Multi-Part Map Troubleshooting

    - by Michael Stephenson
    Scenario I came across a nice little one with multi-part maps the other day. I had an orchestration where I needed to combine 4 input messages into one output message like in the below table:   Input Messages Output Messages Company Details Member Details Event Message Member Search Member Import   I thought my orchestration was working fine but for some reason when I was trying to send my message it had no content under the root node like below <ns0:ImportMemberChange xmlns:ns0="http://---------------/"></ns0:ImportMemberChange>   My map is displayed in the below picture. I knew that the member search message may not have any elements under it but its root element would always exist. The rest of the messages were expected to be fully populated. I tried a number of different things and testing my map outside of the orchestration it always worked fine. The Eureka Moment The eureka moment came when I was looking at the xslt produced by the map. Even though I'd tried swapping the order of the messages in the input of the map you can see in the below picture that the first part of the processing of the message (with the red circle around it) is doing a for-each over the GetCompanyDetailsResult element within the GetCompanyDetailsResponse message. This is because the processing is driven by the output message format and the first element to output is the OrganisationID which comes from the GetCompanyDetailsResponse message. At this point I could focus my attention on this message as the xslt shows that if this xpath statement doesn’t return the an element from the GetCompanyDetailsResponse message then the whole body of the output message will not be produced and the output from the map would look like the message I was getting. <ns0:ImportMemberChange xmlns:ns0="http://---------------/"></ns0:ImportMemberChange> I was quickly able to prove this in my map test which proved this was a likely candidate for the problem. I revisited the orchestration focusing on the creation of the GetCompanyDetailsResponse message and there was actually a bug in the orchestration which resulted in the message being incorrectly created, once this was fixed everything worked as expected. Conclusion Originally I thought it was a problem with the map itself, and looking online there wasn’t really much in the way of content around troubleshooting for multi-part map problems so I thought I'd write this up. I guess technically it isn't a multi-part map problem, but I spend a good couple of hours the other day thinking it was.

  • Wubi no longer supports install to fakeraid?

    - by Ryan
    About a week ago I used wubi to install ubuntu onto one of my two raid1 devices in windows 7. I tried to do the same this week on the same mobo/drive combo and now I can't get it to install. It gives me first an "invalid prefix" during the install and then says "completing install" followed by a crash into busybox with a warning that the raid can't be mounted because it already was mounted. Has there been a change in wubi or something in the recent past?

  • A music player that can handle multiple artist tags

    - by Keidax
    The mp3 format can handle multiple artists per track (in the form of "artist1\artist2"), and as far as I know other modern music formats can do the same thing. However, Rhythmbox (my default music player) seems to be capable of only reading the first artist. Are there any music players that can read and sort songs with multiple artists, or a plugin for Rhythmbox that can provide this functionality?

  • Stuff to read up on pricing applications

    - by tux91
    I'm about to release an app and I have no idea what would be the ideal pricing point. I'm not sure how pricing high and selling few copies will compare in revenue to pricing low and selling lots of copies in my case. Can somebody point me to books/articles/blog posts/etc that elaborate on the subject, preferably taking into account stuff like competition, number of features, being the first one to the market, research if this kind of app is even needed, etc?
