• The changing shape of the Business Intelligence marketplace: Applications vs. Platforms

  - by GavinPayneUK

  I recently read the latest Gartner Magic Quadrant for Business Intelligence ( link ) which put Microsoft as a leader.  However, what was more interesting for me than Microsoft’s success was how as an industry we see BI as a single marketplace, business requirement and vision, despite in my view it now being two separate areas: BI applications and BI platforms . As this article will discuss in more depth we now have two communities with differing requirements, our IT departments and our business...(read more)

  Les 4 tendances qui changeront (peut-être) la BI Dans les trois ans à venir, selon Gartner Dans le cadre de ses Prédiction 2011, le cabinet Gartner a identifié quatre grandes évolutions qui devraient impacter le domaine de la Business Intelligence. Ces prévisions restent hypothétiques mais elle s'appuie tout de même sur des tendances lourdes observables.

• How to make pulseaudio and ubuntu detect the same audio device as alsa driver

  - by Kiwy

  I use Ubuntu 14.04 x64 and I use gnome-shell on my laptop. I have a Bose companion 5 (which is basically a USB sound system) and a HDMI port, both does work perfectly when I just boot with the cable plugin. However, when my laptop go to sleep or get unplugged from those two outputs, if I plug back the device, I end up without any hardware detection (only the built-in speakers) from pulse and gnome-shell sound output selector while if I use alsamixer, the device look up and ready. gstreamer-properties allow me to select and test effectively any device but while alsa recognize any device on the run, pulse is not capable of handling things correctly, my question is then: How can I make pulse detect and use the same hardware as alsa, or how to remove completely and gracefully pulseaudio (meaning volume applet running in gnome shell) I don't mind if the project implies to recompile half gnome shell if it implies those audio outputs work all the time. Pulse does not list my soundcard when I use command pactl list cards while the module plug&play for sound card is loaded in pactl list modules. I really don't know what to do, the behavior seems pretty random.

• Skype sounds sizzle/distorted/bad

  - by Filubuntu

  I have the same problem as described in the questions skype notification sounds sizzled and bad sound on login to skype. But it is not only the login, notification, but also when talking to somebody. I tried the solution to remove/re-install skype and most of the solutions in this questions, e.g. checking mixer, sound settings and installing alsa-hda-dkms (incl. system restart). After installing skype (and even after upgrade to skype 4.0) in Ubuntu 12.04 (AMD 64) there was no sound at all. I followed the first step of the SoundTroubleshootingProcedure and at least there is now sound: sudo add-apt-repository ppa:ubuntu-audio-dev/ppa; sudo apt-get update;sudo apt-get dist-upgrade; sudo apt-get install linux-sound-base alsa-base alsa-utils gdm ubuntu-desktop linux-image-`uname -r` libasound2; sudo apt-get -y --reinstall install linux-sound-base alsa-base alsa-utils gdm ubuntu-desktop linux-image-`uname -r` libasound2; killall pulseaudio; rm -r ~/.pulse*; sudo usermod -aG `cat /etc/group | grep -e '^pulse:' -e '^audio:' -e '^pulse-access:' -e '^pulse-rt:' -e '^video:' | awk -F: '{print $1}' | tr '\n' ',' | sed 's:,$::g'` `whoami` The jittering sound would sometimes disappear, e.g. on the Echo-Testcall after replaying the recorded part. And I noticed that if I let music play in the rhythmbox and then start skype, the sound is fine. So I have a weak solution, but I would be glad it would work without this detour. As requested: My sound card is a an "AMD High Definition Audio Device" called Advanced Micro Devices (AMD) Hudson Azalia controller (rev01), subsystem Lenovo Device 21ea (according to sysinfo) on a Lenovo Thinkpad Edge 525.

• How can I play 24Bit 96000Hz vinyl rips?

  - by Peter

  I am getting music through the Nvidia HDMI but it is all down-sampled to 44000Hz. I have spent at least 3 hours searching for an answer yesterday. I use Pulse Volume and I even changed the default settings in the Pulse folder to 96000 but it does not work. Though 5.1 sound works perfectly. They all work well in Windows 7, but I prefer to use Ubuntu. All the config files for all the programs are in the etc folder, then look in the pulse folder, and there are 3 three files, 2 of these I changed the permissions and I changed 16 and 44000 to 24 and 96000 as I had read in another forum, but it worked for them and not for me. Though 5.1 works as I have special mp4 file that can check each channel. I did alot of restarts and checking after these changes as nothing had happened, my amp tells me the freq of the signal, which does work which I have tested on Windows 7. I have also gone to systems to download the latest driver for mu Nvidia card. But even if it does not work, I guess I can always play Cd's. But I think my player have become more unstable since I changed the configs, so I may uninstall and install Pulse Volume Control again.

• $.fadeTo/fadeOut() operations on Table Rows in IE fail

  - by Rick Strahl

  Here’s a a small problem that one of customers ran into a few days ago: He was playing around with some of the sample code I’ve put out for one of my simple jQuery demos which deals with providing a simple pulse behavior plug-in: $.fn.pulse = function(time) { if (!time) time = 2000; // *** this == jQuery object that contains selections $(this).fadeTo(time, 0.20, function() { $(this).fadeTo(time, 1); }); return this; } it’s a very simplistic plug-in and it works fine for simple pulse animations. However he ran into a problem where it didn’t work when working with tables – specifically pulsing a table row in Internet Explorer. Works fine in FireFox and Chrome, but IE not so much. It also works just fine in IE as long as you don’t try it on tables or table rows specifically. Applying against something like this (an ASP.NET GridView): var sel = $("#gdEntries>tbody>tr") .not(":first-child") // no header .not(":last-child") // no footer .filter(":even") .addClass("gridalternate"); // *** Demonstrate simple plugin sel.pulse(2000); fails in IE. No pulsing happens in any version of IE. After some additional experimentation with single rows and various ways of selecting each and still failing, I’ve come to the conclusion that the various fade operations in jQuery simply won’t work correctly in IE (any version). So even something as ‘elemental’ as this: var el = $("#gdEntries>tbody>tr").get(0);$(el).fadeOut(2000); is not working correctly. The item will stick around for 2 seconds and then magically disappear. Likewise: sel.hide().fadeIn(5000); also doesn’t fade in although the items become immediately visible in IE. Go figure that behavior out. Thanks to a tweet from red_square and a link he provided here is a grid that explains what works and doesn’t in IE (and most last gen browsers) regarding opacity: http://www.quirksmode.org/js/opacity.html It appears from this link that table and row elements can’t be made opaque, but td elements can. This means for the row selections I can force each of the td elements to be selected and then pulse all of those. Once you have the rows it’s easy to explicitly select all the columns in those rows with .find(“td”). Aha the following actually works: var sel = $("#gdEntries>tbody>tr") .not(":first-child") // no header .not(":last-child") // no footer .filter(":even") .addClass("gridalternate"); // *** Demonstrate simple plugin sel.find("td").pulse(2000); A little unintuitive that, but it works. Stay away from <table> and <tr> Fades The moral of the story is – stay away from TR, TH and TABLE fades and opacity. If you have to do it on tables use the columns instead and if necessary use .find(“td”) on your row(s) selector to grab all the columns. I’ve been surprised by this uhm relevation, since I use fadeOut in almost every one of my applications for deletion of items and row deletions from grids are not uncommon especially in older apps. But it turns out that fadeOut actually works in terms of behavior: It removes the item when the timeout’s done and because the fade is relatively short lived and I don’t extensively test IE code any more I just never noticed that the fade wasn’t happening. Note – this behavior or rather lack thereof appears to be specific to table table,tr,th elements. I see no problems with other elements like <div> and <li> items. Chalk this one up to another of IE’s shortcomings. Incidentally I’m not the only one who has failed to address this in my simplistic plug-in: The jquery-ui pulsate effect also fails on the table rows in the same way. sel.effect("pulsate", { times: 3 }, 2000); and it also works with the same workaround. If you’re already using jquery-ui definitely use this version of the plugin which provides a few more options… Bottom line: be careful with table based fade operations and remember that if you do need to fade – fade on columns.© Rick Strahl, West Wind Technologies, 2005-2010Posted in jQuery

• How to make pulseaudio work again?

  - by Pawel M.

  I was having problems with sound (mono only output), so following advice from another askubuntu question I made some edits in /etc/pulse/default.pa After rebooting I had no sound at all. So I deleted /etc/pulse/default.pa entirely and tried another reboot. I did not backup the file (stupid, I know). How to come back to working config? edit: I tried: sudo apt-get remove pulseaudio (reboot) sudo apt-get install pulseaudio (reboot) It's still not working. The file /etc/pulse/default.pa is missing. Here's what pulseaudio and pacmd commands show: $ pulseaudio E: [pulseaudio] main.c: Daemon startup without any loaded modules, refusing to work. $ pacmd No PulseAudio daemon running, or not running as session daemon.

• Types in Union or Concat cannot be constructed with hierarchy

  - by user927777

  I am trying to run a query very similar to the following: (from bs in DataContext.TblBookShelf join b in DataContext.Book on bs.BookID equals b.BookID where bs.BookShelfID == bookShelfID select new BookItem { Categories = String.Join("<br/>", b.BookCategories.Select(x => x.Name).DefaultIfEmpty().ToArray()), Name = b.Name, ISBN = b.ISBN, BookType = "Shelf" }).Union(from bs in DataContext.TblBookShelf join bi in DataContext.TblBookInventory on bs.BookID equals bi.BookID select new BookItem { Categories = String.Join("<br/>", bi.BookCategories.Select(x => x.Name).DefaultIfEmpty().ToArray()), Name = bi.Name, ISBN = bi.ISBN, BookType = "Inventory" }); I am receiving "Types in Union or Concat cannot be constructed with hierarchy" after the statement executes, I need to to be able to get a list of categories to display with each book. If anyone could shed some light on a possible solution, it would be greatly appreciated.

• New site – and a special offer

  - by Red Gate Software BI Tools Team

  SSAS Compare has a brand new website! The old page was thrown together in the way that most Red Gate labs sites tend to be — as experimental sites for experimental products. We’ve been developing SSAS Compare for a while now, so we decided it was time for something a bit prettier. The new site is mostly the work of Andrew, our marketing manager, who has all sorts of opinions about websites. One of the opinions Andrew has is that his photo should be on every site on the internet, or at least every Red Gate site on the internet, and that’s why his handsome visage now appears on the SSAS Compare page. Well, that isn’t quite true. According to Andrew, people download more software when they have photos of human beings to look at. We want as many people to try SSAS Compare as possible, so we got the team together for an intimate photoshoot directed by Red Gate’s resident recorder of light, Dom Reed (aka Mr Flibble). The photo will appear on the site as soon as Dom is finished photoshopping us into something more palatable, which is a big job. Until then, you’ll have to put up with Andrew. We’ve also used the new site to announce a special offer. Right now, SSAS Compare is still a free beta, but by signing up to our Early Access Program, you’ll get a 20% discount when we release SSAS Compare as a fully-fledged product. We’ll use your email address to send you news and updates about business intelligence tools from Red Gate (and nothing else). If that sounds good to you, go to the SSAS Compare site to sign up. By the way, the BI Tools team wasn’t the only thing Dom photographed last week. Remember Noemi’s blog about the flamenco dance? We’ll be at SQL Saturday in our home town of Cambridge this Saturday (8th September), handing out flyers of a distinctly Mediterranean flavour. If you’re attending, be sure to say hello!

• Exalytics Increases Customer Revenue, and Saves Time, Risk & Cost

  - by Mike.Hallett(at)Oracle-BI&EPM

  We are getting some great proof point stories now from our customers who are succeeding with the Exalytics in-memory system for OBI and Essbase.  See below for some recent testimony: San Diego Unified School District Harnesses Attendance, Procurement, and Operational Data with Oracle Exalytics, Generating $4.4 Million in Savings: according to independent assessment by Mainstay Salire, the district is on track to achieve substantial benefits from the Oracle Exalytics solution, including an $8.25 million increase in attendance revenue, $75,000 a year savings in operational efficiencies, and $1 million in hardware cost avoidance. NilsonGroup chooses Oracle Exalytics In-Memory Machine as their solution to access critical data to keep its stores competitive with real-time Mobile BI: it took only “3 days to get up and running” with Exalytics.  Video Nykredit, in the Danish Financial Sector, describes their experiences from testing the Exalytics Business Intelligence Machine: “it was up and running within 4 days” with “more intuitive dashboards” and “up to 70x better performance” and “cheaper maintenance and lower total cost of ownership”. Video Sodexo chose Oracle Exalytics as their business analytics platform; accelerating Essbase “more than 8x” performance for more than 2,000 Excel-addin users, “significantly changing how people in information management now deal with data”.  Video Polk, Savvis, Nykredit, and Key Energy describe testing of the Oracle Exalytics In-Memory Machine: to “reach more users than we ever have before”, “to fly through the data without impeding the analytic process”, “drive our enterprise groups into this tool instead of having departmental solutions”, and the “advanced visualisation this product enables”.  Video

• SSAS Compare version 1.0 released

  - by Red Gate Software BI Tools Team

  We’re pleased to announce that SSAS Compare version 1.0 has been released as a free tool. Version 1.0 includes: Comparisons of live databases and XMLA or Analysis Services Project files MDX syntax diffs and highlighting Server comparisons Deployment wizard with summaries of scripted actions Bug fixes and engine and UI refinements We’ve tested it on as many cube configurations as we could find (not just good old AdventureWorks!), but we can’t provide support for free tools — so if you’re reliant on SSAS Compare for your cube deployment, use it at your own risk. See the user license agreement in the installer for more details. SSAS Compare’s come a long way from its humble beginnings as an internal tool first developed for Red Gate’s own BI developers. Today’s SSAS Compare is now much more stable — not to mention much easier to use — and something the team is proud to have released with Red Gate’s name on. Next: Deployment Manager We’re working on integrating SSAS Compare cube deployment with our new Deployment Manager tool, so you’ll be able to create cube deployment scripts and automate the deployment process, too.  We’re documenting the process in a white paper we’ll publish online in the next week. Thank you! Thanks to all the SSAS Compare users out there. Without your feedback, we could never have produced such a stable product so quickly. We hope you continue to find useful. See you in Deployment Manager!

• 4.0/WCF: Best approach for bi-idirectional message bus?

  - by TomTom

  Just a technology update, now that .NET 4.0 is out. I write an application that communicates to the server through what is basically a message bus (instead of method calls). This is based on the internal architecture of the application (which is multi threaded, passing the messages around). There are a limited number of messages to go from the client to the server, quite a lot more from the server to the client. Most of those can be handled via a separate specialized mechanism, but at the end we talk of possibly 10-100 small messages per second going from the server to the client. The client is supposed to operate under "internet conditions". THis means possibly home end users behind standard NAT devices (i.e. typical DSL routers) - a firewalled secure and thus "open" network can not be assumed. I want to have as little latency and as little overhad for the communication as possible. What is the technologally best way to handle the message bus callback? I Have no problem regularly calling to the server for message delivery if something needs to be sent... ...but what are my options to handle the messagtes from the server to the client? WsDualHttp does work how? Especially under a NAT scenario? Just as a note: polling is most likely out - the main problem here is that I would have a significant overhead OR a significant delay, both aren ot really wanted. Technically I would love some sort of streaming appraoch, where the server can write messags to a stream while he generates them and they get sent to the client as they come. Not esure this is doable with WCF, though (if not, I may acutally decide to handle the whole message part outside of WCF and just do control / login / setup / destruction via WCF).

When I run it the progress bar will pulse for around 10 secs as meant to and then move on to downloading and will show the progress but when finished it will not move on to the next step it just locks up. import sys import time import pygtk import gtk import gobject import threading import urllib import urlparse class WorkerThread(threading.Thread): def __init__ (self, function, parent, arg = None): threading.Thread.__init__(self) self.function = function self.parent = parent self.arg = arg self.parent.still_working = True def run(self): # when does "run" get executed? self.parent.still_working = True if self.arg == None: self.function() else: self.function(self.arg) self.parent.still_working = False def stop(self): self = None class MainWindow: def __init__(self): gtk.gdk.threads_init() self.wTree = gtk.Builder() self.wTree.add_from_file("gui.glade") self.mainWindows() def mainWindows(self): self.mainWindow = self.wTree.get_object("frmMain") dic = { "on_btnNext_clicked" : self.mainWindowNext, } self.wTree.connect_signals(dic) self.mainWindow.show() self.installerStep = 0 # 0 = none, 1 = preinstall, 2 = download, 3 = install info, 4 = install #gtk.main() self.mainWindowNext() def pulse(self): self.wTree.get_object("progress").pulse() if self.still_working == False: self.mainWindowNext() return self.still_working def preinstallStep(self): self.wTree.get_object("progress").set_fraction(0) self.wTree.get_object("btnNext").set_sensitive(0) self.wTree.get_object("notebook1").set_current_page(0) self.installerStep = 1 WT = WorkerThread(self.heavyWork, self) #Would do a heavy function here like setup some thing WT.start() gobject.timeout_add(75, self.pulse) def downloadStep(self): self.wTree.get_object("progress").set_fraction(0) self.wTree.get_object("btnNext").set_sensitive(0) self.wTree.get_object("notebook1").set_current_page(0) self.installerStep = 2 urllib.urlretrieve('http://mozilla.mirrors.evolva.ro//firefox/releases/3.6.3/win32/en-US/Firefox%20Setup%203.6.3.exe', '/tmp/firefox.exe', self.updateHook) self.mainWindowNext() def updateHook(self, blocks, blockSize, totalSize): percentage = float ( blocks * blockSize ) / totalSize if percentage > 1: percentage = 1 self.wTree.get_object("progress").set_fraction(percentage) while gtk.events_pending(): gtk.main_iteration() def installInfoStep(self): self.wTree.get_object("btnNext").set_sensitive(1) self.wTree.get_object("notebook1").set_current_page(1) self.installerStep = 3 def installStep(self): self.wTree.get_object("progress").set_fraction(0) self.wTree.get_object("btnNext").set_sensitive(0) self.wTree.get_object("notebook1").set_current_page(0) self.installerStep = 4 WT = WorkerThread(self.heavyWork, self) #Would do a heavy function here like setup some thing WT.start() gobject.timeout_add(75, self.pulse) def mainWindowNext(self, widget = None): if self.installerStep == 0: self.preinstallStep() elif self.installerStep == 1: self.downloadStep() elif self.installerStep == 2: self.installInfoStep() elif self.installerStep == 3: self.installStep() elif self.installerStep == 4: sys.exit(0) def heavyWork(self): time.sleep(10) if __name__ == '__main__': MainWindow() gtk.main()

• Java - Which Business Intelligence (BI) platform can I embed with my commercial software for free?

  - by Yatendra Goel

  I am developing a java application and I want to use: Reporting Analysis Data Mining Data Integration tools to be shipped with my commercial application that I am NOT going to sell as an open source application. So I want to know which tools I can use in my app. Actually I am evaluating PENTAHO and JASPER but I don't understand licensing issues. Some comes under GPL, some under LGPL, some under CPL... so I am very confused about those.

• Bi-directional communication with 1 socket - how to deal with collisions?

  - by Zwei Steinen

  Hi, I have one app. that consists of "Manager" and "Worker". Currently, the worker always initiates the connection, says something to the manager, and the manager will send the response. Since there is a LOT of communication between the Manager and the Worker, I'm considering to have a socket open between the two and do the communication. I'm also hoping to initiate the interaction from both sides - enabling the manager to say something to the worker whenever it wants. However, I'm a little confused as to how to deal with "collisions". Say, the manager decides to say something to the worker, and at the same time the worker decides to say something to the manager. What will happen? How should such situation be handled? P.S. I plan to use Netty for the actual implementation. Thank you very much in advance!
