• SQLAuthority News – Whitepaper Download – Using Star Join and Few-Outer-Row Optimizations to Improve Data Warehousing Queries

  - by pinaldave

  Size of the database is growing every day. Many organizations now a days have more than TB of the Data in their system. Performance is always part of the issue. Microsoft is really paying attention to the same and also focusing on improving performance for Data Warehousing. Microsoft has recently released whitepaper on the performance tuning subject of Data Warehousing. Here is the abstract about the whitepaper from official site: In this white paper we discuss two of the new features introduced in SQL Server 2008, Star Join and Few-Outer-Row optimizations. These two features are in SQL Server 2008 R2 as well.  We test the performance of SQL Server 2008 on a set of complex data warehouse queries designed to highlight the effect of these two features and observed a significant performance gain over SQL Server 2005 (without these two features). The results observed also apply to SQL Server 2008 R2.  On average, about 75 percent of the query execution time has been reduced, compared to SQL Server 2005. We also include data that shows a reduction in the number of rows processed and improved balance in parallel queries, both of which highlight the important role the Star Join and Few Outer-Row features played. I encouraged all of those interested in Data Warehouse to read it and see if they can learn the tricks.

• Very slow write access to SSD disks on some Asus P8Z77 motherboards

  - by lenik

  I have Asus P8Z77-V LK motherboard, that ran Mint 13 (based on Ubuntu 12.04) just perfectly, but recently I've tried to install Mint 17 and noticed abysmal write performance. Write speed on SSD disk was about 1.5MB/sec, when it's supposed to be in 150-250MB/sec range. For write testing I've used dd if=/dev/zero of=/dev/sda bs=10M count=10 while booted up from LiveCD. I have also tested the read speed with hdparm -tT /dev/sda and got about 440MB/sec -- that's normal. I can tell, the read performance has not degraded at all and is not an issue here. Since I had a few different SSD disks and few motherboards, I've tested and tested and here are results: Asus P8H77 works fine with Mint13, has very slow write speed starting from Mint14. Asus P8Z77-V LK works with Mint13, has very slow write speed starting from Mint14. Asus P8Z77-V PRO works with Mint13, and works just fine with Mint14, 15, 16 and 17. The only difference between "PRO" version and others is that it has extra SATA controller onboard (in addition to the Z77 chipset SATA controller) providing extra 2 SATA ports. SSD disks work fine with "PRO" version when connected to the native SATA ports as well as to the ports provided by extra SATA controller, so this does not look like a hardware issue. As far as I can tell, there's something changed in the kernel while going from 3.2 to 3.5, that affects the detection of onboard SATA controller for Asus P8*77 motherboards, that screws up the write speed for SSD drives. Could anyone shed some light on how to fix this issue or, possibly, give a pointer to a more suitable place to ask this question?

• Is NAN suitable for communicating that an invalid parameter was involved in a calculation?

  - by Arman

  I am currently working on a numerical processing system that will be deployed in a performance-critical environment. It takes inputs in the form of numerical arrays (these use the eigen library, but for the purpose of this question that's perhaps immaterial), and performs some range of numerical computations (matrix products, concatenations, etc.) to produce outputs. All arrays are allocated statically and their sizes are known at compile time. However, some of the inputs may be invalid. In these exceptional cases, we still want the code to be computed and we still want outputs not "polluted" by invalid values to be used. To give an example, let's take the following trivial example (this is pseudo-code): Matrix a = {1, 2, NAN, 4}; // this is the "input" matrix Scalar b = 2; Matrix output = b * a; // this results in {2, 4, NAN, 8} The idea here is that 2, 4 and 8 are usable values, but the NAN should signal to the receipient of the data that that entry was involved in an operation that involved an invalid value, and should be discarded (this will be detected via a std::isfinite(value) check before the value is used). Is this a sound way of communicating and propagating unusable values, given that performance is critical and heap allocation is not an option (and neither are other resource-consuming constructs such as boost::optional or pointers)? Are there better ways of doing this? At this point I'm quite happy with the current setup but I was hoping to get some fresh ideas or productive criticism of the current implementation.

• gd dissapears from apache server

  - by juanlu

  Hi. We have a web server (Debian, with Apache2, PHP4 and MySQL) used in an Intranet. It's main use is to serve pages with data and graphs generated dynamically (using jpgraph) from the data stored in DB. It has worked rock solid for several years, but this week we have found that everything related to graphs is not working. This includes jpgraph and gnuplot generated figures, both dependent on library gd. Also there are no references to "gd" in phpinfo(), and any direct call to gd functions (like gd_info()) results in an error. We have tried to reinstall php4-gd (and restarting Apache) with no result. Obviously we have done something wrong, but we cannot figure out what it is. What can we have done? Is there any other diagnosis we can do to isolate the problem? Thanks.

• cannot mount remote partition using fstab/fuse

  - by HorusKol

  Using a combination of http://ubuntu-tutorials.com/2007/01/02/mount-remote-directories-securely-with-ssh-ubuntu-6061-610/ and http://www.tuxfiles.org/linuxhelp/fstab.html I figured I could mount the root of another computer to somewhere on my new laptop to make it easier to transfer files and stuff. Now, I can connect through SSH and browser the files through an ad-hoc mount - but I would like to be able to do this automatically, and so had a look at fstab. my new entry in fstab is: remote_comp:/ /var/remote_comp fuse defaults 0 0 but testing with mount -a results in the following error: /bin/sh: remote_comp:/: not found I thought the problem was because I was trying to mount the root of the other computer, but even trying sub-directories result in the same error message.

• On an unencrypted public wi-fi hotspot, what exactly is a packet sniffer doing to get another computer's packet?

  - by hal10001

  I get mixed results when reading information security articles, some of them stating that in order to do something similar you need to also setup some sort of honeypot with a running access point and local Web server to intercept traffic. Then other articles seem to indicate you don't need that, and you can just run Wireshark, and it will detect all packets being sent on the network. How could that be, and what exactly is a packet sniffer doing to get those packets? Does this involve intercepting wireless signals transmitted over the wireless protocol and frequency via the NIC on the computer running a program like Wireshark?

• Bluetooth adapter turned from working fine to unrecognized

  - by easoncxz

  i had been using bluetooth fine, with devices working, but today when i turned on my computer again bluetooth strangely failed. there is a bluetooth icon on the top bar, showing "bluetooth on", but if i click on the "bluetooth settings" item, a system settings window shows up and shows me a bluetooth on-off switch which is disabled (i.e. fixed to off). more information about my case: i am a new linux used, coming from windows, and do not know supposedly-obvious commands. i am using a laptop. it initially doesn't have bluetooth. i bought a built-in type (instead of USB type) bluetooth module, and added it inside the laptop. hence, i do not have a specific FN+* key for bluetooth. in windows, i needed to install an additional driver that was intended for other machines in my laptop's seires which have built-in (i.e. factoryly built-in)j bluetooth modules. the Fn+* key seemed to only affect wifi under ubuntu. i have been successfully using magicmouse with my later-added built-in bluetooth module/adapter on both windows and ubuntu i have been trying to tweak the magicmouse scrolling speed with commands rmmod something, modprobe hid_magicmouse --scroll_speed=45 --scroll_acceleration=30 or something, then added a file `/etc/modprobe.d/magicmouse.conf". the mouse seemed to be working fine with these changes. now if i run commands like hcitool dev, the shell tells me that i do not have any "Devices" or "adapters". i seem to have bluez installed, because when i type "blue" then tab-autocomplete, a bunch of commands like bluez-test-device pops up. -- update -- some commands and their results: easoncxz@eason-Aspire-4741-ubuntu:/etc$ hcitool dev Devices: easoncxz@eason-Aspire-4741-ubuntu:/etc$ hcitool scan Device is not available: No such device easoncxz@eason-Aspire-4741-ubuntu:/etc$ rfkill list 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no 1: acer-wireless: Wireless LAN Soft blocked: no Hard blocked: no 2: acer-bluetooth: Bluetooth Soft blocked: no Hard blocked: no easoncxz@eason-Aspire-4741-ubuntu:/etc$ rfkill list 0: phy0: Wireless LAN Soft blocked: yes Hard blocked: no 1: acer-wireless: Wireless LAN Soft blocked: yes Hard blocked: no 2: acer-bluetooth: Bluetooth Soft blocked: yes Hard blocked: no

• Personal knowledge base [closed]

  - by AlexLocust

  Possible Duplicate: How do you manage your knowledge base? Hello. Now I am using easy writing pad for scratches while doing some researches, solving troubles or doing workarounds. But.. you now, it's really difficult to remember all details of founded solution and it's alternatives after few months. And writing pad is not wery useful. Usually writing pad doesn't contains half of needed inforation: links founded in internet, output of some test commands and etc. Now I'am looking for a tool for storing information about my researches and it's results. Basic reqirements: ability to store files; ability to store formatted text (kind of HTML will be nice) with hyperlinks and code snippets; tags on notes; easy to use. Now I'am thinking about some kind of file-system organized storage, but I think it will be inconvenient. Another thinks is local wiki or blog. So, my question is: How do you organize you knowlege base? What tools do you use, and what "pros and cons".

• Taking our Friendships to the next level.

  - by RedAndTheCommunity

  Red Gate have been running the Friends of Red Gate program for years now, and over that time we've built some great relationships with some truly awesome members of the SQL and .NET communities. When I took over the running of the program from Annabel in 2011, I was overwhelmed by the enthusiasm and commitment of our Friends. There were just so many of them, however, that it was hard to make the most of the relationships we had with people, and I wanted to fix that. I decided to survey all our Friends, to find out what they wanted to get out of, and put into, being in the Friends of Red Gate (FoRG) program. From the results of that survey, I identified 30 FoRGs that were really willing and able to go that step further to help Red Gate improve their tools, improve their relationship with the community, and improve the Friends of Red Gate program. Those 30 Friends of Red Gate have been awarded 'FoRG+' status. That means they'll: Have a closer relationship with the product teams, by getting involved in projects Have even more access to the inside track about the tools they're interested in Get the opportunity to come visit us at the Red Gate office and really influence the development of the tools. Plus more, depending on how the individual FoRG+ wants to work with us. This doesn't mean I've forgotten our other Friends; I'm working on ways to improve their experience of the Friends of Red Gate program. I'll write about them in another post. If you're an existing Friend of Red Gate, and you're interested in finding out how to get involved in the FoRG+ program, then I'd love to chat to you. For anyone that's interested in joining the Friend of Red Gate program, take a look at the web page dedicated to the program, and get in touch at [email protected] to be put on the waiting list for our 2013 program.

• Slash Notation IP - What is what?

  - by Nirmal

  We just signed up with a new ISP and we got a static IP from them. Our previous ISP just gave one IP and we were able to configure our web server using that. Now, we have got this new IP with a slash notation. This type is new to me. When I used the CIDR calculator, it gave me the following results: 202.184.7.52/30 IP: 202.184.7.52 Netmask: 255.255.255.252 Number of hosts: 2 Network address: 202.184.7.52 Broadcast address: 202.184.7.55 Can someone please help me by explaining what these are? I could not understand what the number of hosts means. Is that telling that I can use two different IP for DNS (A) records? Also, which one should I setup in my router? The network address or broadcast address? Thank you very much for any answer you may provide.

• Inspiration

  - by Oracle Campus Blog

  Once again, I find myself back in Seoul – ASEM Tower, 16th Floor in a mobile room. I’m busy preparing for the interview process that is about to take place for Oracle Korea’s GIP 7th (Graduate Intake Program): scheduling the first round interviews, organizing interview guidelines, educating interviewers on the process and framework and  getting all the logistics ready for the 1st round interview. Seoul or Korea rather is a fascinating place. Highly efficient, the utmost respect for seniors and results orientated. When students come in for an interview at first it was hard to tell them apart – there seems to be accepted interview attire that must be worn when attending an interview. Males and Females, all dress in black suits, with white shirts underneath – with males to wear simple and dark colored ties. During the interview, they would all sit very upright, all would bow when entering the room, place their hands on the laps and very often they would hold minimal eye contact. They would project their voice loud to portray confidence, they would talk in the Korean formal dialect at all times and will treat every question, every moment with extreme clarity and the utmost professionalism. When the interview concludes, they will all stand hands by their sides, bow 90 degrees and thank all the interviewers for their precious time and opportunity. As soon as they leave the interview room, I could hear all their sighs of relief and commended each other on their efforts. More and more I learn about the Korean culture it inspires me. Their patriotism, their respect for each, their values, their appreciation, their motivation, their desires and passion – it truly was an experience for me (even as a recruiter) and can’t help but feel truly impressed and motivated to live for every moment.

• SNMP - Value of CPU processor load not reflecting reality

  - by Ovesh

  Trying to plot CPU load on my server, with the following hardware: ProLiant DL360p Gen8 (same behavior on ProLiant DL360 G7). The machine is running VMWare ESXi5.1 To create a CPU spike I run dd if=/dev/zero of=/dev/null, and I know the CPU is overloaded, because I can see a correlating spike in the graphs displayed on vCenter. However, running this snmpwalk: snmpwalk -v 1 -c ******** 192.168.MY_IP 1.3.6.1.2.1.25.3.3.1.2 Shows the following results: iso.3.6.1.2.1.25.3.3.1.2.1 = INTEGER: 3 iso.3.6.1.2.1.25.3.3.1.2.2 = INTEGER: 2 iso.3.6.1.2.1.25.3.3.1.2.3 = INTEGER: 2 iso.3.6.1.2.1.25.3.3.1.2.4 = INTEGER: 3 Am I not looking into the right MIB? Should I be multiplying these by a constant? By the way, using HP Agentless Monitoring I was able to get some cpu stats, but not what I'm looking for, at least nothing I could find wading through these MIBs.

• Automating Nightly Build Installation?

  - by StickFigs

  Every night a new build of my program is made and copied to a /Builds/ folder. I have a Windows machine that I want to have uninstall the program then install the latest version of the program from the /Builds/ folder. Currently the build results in two separate setup.exe files which are InstallShield installation wizard executables. I want this to happen every night after the build finishes: Uninstall first component. Uninstall second component. Install newest build of first component using setup.exe. Install newest build of second component using setup.exe. I figured that there probably already exists a software solution for automating installations like this. Are there any software solutions out there than can do what I need? Preferrably for free?

• Google Analytics async=true seems wrong in the Google documentation?

  - by leeand00

  In the Google Analytics async example, they state that in order to include more than one tracker, you need to setup your pages for asyncrous tracking, and they do so using the following code: <script type="text/javascript"> _gaq.push( ['_setAccount', 'UA-XXXXX-1'], ['_trackPageview'], ['b._setAccount', 'UA-XXXXX-2'], ['b._trackPageview'] ); (function() { var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true; ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s); })(); </script> The second tracker is not receiving any results. After looking at my tracking codes to ensure they are correct, I noticed that the ga.async = true statement is specified differently most of the time and is never set to a value of true, it's often set to async but never true. Could this be stopping my Analytics data from posting to the second tracker? or might it be something else? Also what calls should I look for in the Net tab in firebug to ensure that GA is being called when the page loads?

• ASP.NET ViewState Tips and Tricks #1

  - by João Angelo

  In User Controls or Custom Controls DO NOT use ViewState to store non public properties. Persisting non public properties in ViewState results in loss of functionality if the Page hosting the controls has ViewState disabled since it can no longer reset values of non public properties on page load. Example: public class ExampleControl : WebControl { private const string PublicViewStateKey = "Example_Public"; private const string NonPublicViewStateKey = "Example_NonPublic"; // DO public int Public { get { object o = this.ViewState[PublicViewStateKey]; if (o == null) return default(int); return (int)o; } set { this.ViewState[PublicViewStateKey] = value; } } // DO NOT private int NonPublic { get { object o = this.ViewState[NonPublicViewStateKey]; if (o == null) return default(int); return (int)o; } set { this.ViewState[NonPublicViewStateKey] = value; } } } // Page with ViewState disabled public partial class ExamplePage : Page { protected override void OnLoad(EventArgs e) { base.OnLoad(e); this.Example.Public = 10; // Restore Public value this.Example.NonPublic = 20; // Compile Error! } }

• Network really slow with TL-WN951N wireless card

  - by Sam

  I literally just installed ubuntu and it seems to be working great except the network is deadly slow. I'm running a TL-WN951N wireless card which can download at about 600-700 KB/s in windows but in Ubuntu the max speed it seems to get is around 5KB/s. I guess I should note that my WAP is only wireless-G but like I said, I can get much better speeds in Windows. I'm testing the speeds by downloading files from here: http://mirror.internode.on.net/pub/test/ Anyone have any idea? I saw some people recommend downloading drivers and compiling them myself but I'm really really new to all of this so would appreciate someone babying me through it so I don't brick my computer!

  We have been running our qmail setup for awhile with no issues. One of our admins has moved to Google Chrome as his main browser and we have noticed something odd. No matter what, when he loads the vqadmin page it errors on him with simply invalid language file. Yet if he loads Firefox, Opera, Safari or shudders IE8 it works fine. Searching google only results in 'Use IE' or 'Set english as your language in the browser'. A: I try to have people avoid IE if possible and B: There is no english option in Chrome.

• Gnome 3 - Multiple Video Cards - Xinerama -- Forced Fallback Mode

  - by Alvin

  Just installed a 2nd nvidia video card -- previously had gnome 3 working perfectly with 2 monitors on a a single video card using twinview tried a number of things thus far twinview on 1 card + xinerama no xinerama no twinview various manual xorg.conf hacks based on random forums (couple references below) xinerama no twinview with and without Extensions Composite The last one is what I'm using now -- it results in a forced fallback mode with Composite Disable set at the end of xorg.conf via nvidia-settings Section "Extensions" Option "Composite" "Disable" EndSection when I disabled that last snippet it boots to gnome 3 full with the left monitor on a black screen and the middle monitor as primary but non-responsive switching to console mode Ctrl+Alt+F1 and then switching back I get 3 black screens with a mouse that can move around but nothing to interact with issue seems related to OpenGL and the multiple video cards -- I can boot into Unity without issue though my Glx-Dock shows up with the black background as barely shows in the screenshot below indicating the OpenGL is not initiated has anyone had any luck with getting Xinerama to work with Multiple NVidia Video Cards with OpenGL support? Found this in the logs while looking a bit further [ 23.208] (II) NVIDIA(1): Setting mode "nvidia-auto-select+0+0" [ 23.254] (WW) NVIDIA(1): The GPU driving screen 1 is incompatible with the rest of the [ 23.254] (WW) NVIDIA(1): GPUs composing the desktop.

• Tuning B2B Server Engine Threads in SOA Suite 11g

  - by Shub Lahiri, A-Team

  Background B2B 11g has a number of parameters that can be tweaked to tune the engine for handling high volumes of messages. These parameters are also known as B2B server properties and managed via the EM console.  This note highlights one aspect of the tuning exercise and describes the different threads, that can be configured to tune the performance of a B2B server. Symptoms The most common indicator of a B2B engine in need of a tuning is reflected in the constant build-up of messages in an internal JMS queue within the B2B server. It is called B2B_EVENT_QUEUE and can be monitored via the Weblogic server console. Whenever such a behaviour is seen, it usually results in general degradation of performance. Remedy There could be many contributing factors behind a B2B server's degradation of performance. However, one of the first places to tune the server from the out-of-the-box, default configuration is to change the number of internal engine threads allocated within the B2B server. Usually the default configuration for the B2B server engine threads is not suitable for high-volume of messaging loads. So, it is necessary to increase the counts for 3 types of such threads, by specifying the appropriate B2B server properties via the EM console, namely, Inbound - b2b.inboundThreadCount Outbound - b2b.outboundThreadCount Default - b2b.defaultThreadCount The function of these threads are fairly self-explanatory. In other words, the inbound threads process the inbound messages that are coming into the B2B server from an external endpoint. Similarly, the outbound threads processes the messages that are sent out from the B2B server. The default threads are responsible for certain B2B server-specific special tasks. In case the inbound and outbound thread counts are not specified, the default thread count also dictates the total number of inbound and outbound threads. As found in any tuning exercise, the optimisation of these threads is usually reached via an iterative process. The best working combination of the thread counts are directly related to the system infrastructure, traffic load and several other environmental factors.

• .NET Properties - Use Private Set or ReadOnly Property?

  - by tgxiii

  In what situation should I use a Private Set on a property versus making it a ReadOnly property? Take into consideration the two very simplistic examples below. First example: Public Class Person Private _name As String Public Property Name As String Get Return _name End Get Private Set(ByVal value As String) _name = value End Set End Property Public Sub WorkOnName() Dim txtInfo As TextInfo = _ Threading.Thread.CurrentThread.CurrentCulture.TextInfo Me.Name = txtInfo.ToTitleCase(Me.Name) End Sub End Class // ---------- public class Person { private string _name; public string Name { get { return _name; } private set { _name = value; } } public void WorkOnName() { TextInfo txtInfo = System.Threading.Thread.CurrentThread.CurrentCulture.TextInfo; this.Name = txtInfo.ToTitleCase(this.Name); } } Second example: Public Class AnotherPerson Private _name As String Public ReadOnly Property Name As String Get Return _name End Get End Property Public Sub WorkOnName() Dim txtInfo As TextInfo = _ Threading.Thread.CurrentThread.CurrentCulture.TextInfo _name = txtInfo.ToTitleCase(_name) End Sub End Class // --------------- public class AnotherPerson { private string _name; public string Name { get { return _name; } } public void WorkOnName() { TextInfo txtInfo = System.Threading.Thread.CurrentThread.CurrentCulture.TextInfo; _name = txtInfo.ToTitleCase(_name); } } They both yield the same results. Is this a situation where there's no right and wrong, and it's just a matter of preference?

• PC On/Off Time Charts Windows Uptime; No Logging Necessary

  - by Jason Fitzpatrick

  Windows: PC On/Off Time is a graphical tool that displays your PC’s uptime, downtime, errors, and more all in a clear and portable package. One of the hassles of using logging tools is that you usually have to enable the logging and then wait for results to pile up before seeing anything useful (such as when you turn on the logging on your router). PC On/Off Time taps right into the event logs your Windows PC is already keeping so you get immediate access to your uptime history. If you look at the screenshot above you can see an accurate picture of the last few weeks of uptime on my computer. October 23-24 I didn’t boot down my PC, the rest of the time I hibernated it overnight when I wasn’t using it, November 1st I installed an SSD (you can see the burst of reboots and short uptimes) and then November 9th there was a brief power outage that caused an unexpected stop (the red arrows on the timeline for the 9th). The free version offers a three-week peek back into your uptime history (upgrade to the Pro version for $12.75 or for free using Trial Pay to unlock your completely uptime history).PC On/Off Time is Windows only.

• Problem with XeTeX (LaTeX) and system fonts

  - by mghg

  I have started to use an enterprise specific class for LaTeX, but have got a problem with usage system fonts in Ubuntu. The class uses the fontspec package, I have therefore been instructed to use XeTeX (i.e. the command xelatex instead of latex or pdflatex). However, the command xelatex testfile.tex results in the following message: ! Package xkeyval Error: `TeX' undefined in families `Ligatures'. See the xkeyval package documentation for explanation. Type H <return> for immediate help. ... l.61 \newfontfamily\headfont{Arial} ? The class has previously been used on Mac and Windows and the font setup is as follows: \newfontfamily\headfont{Arial} \newcommand\texthead[1]{\headfont #1} \setromanfont{Georgia} \setmainfont{Georgia} \setsansfont[Scale=MatchLowercase]{Verdana} It has been suggested that since XeTeX makes use of system fonts and the class file has worked flawlessly on Mac and Windows, the problem might be that Arial is not a name used in Ubuntu. I have tried to exchange Arial with Ubuntu Light in the setup code above, but that have not been any improvement. Any suggestions please on how to move forward?

What are the risks of doing so?
