• How to get headphones and speakers working at the same time?

  - by Borek

  I have a Gigabyte P55-UD3 motherboard which comes with a Realtek sound card and audio header for the front panel. My headset is permanently connected to the front panel (mic in, headphones in) and I also have speakers connected at the rear of the computer. What I want to achieve is that both the headphones and the speakers work at the same time. On my old PC with Realtek, I was able to do this by clicking "Device advanced settings" in the Realtek HD Audio Manager and then clicking "Make front and rear output devices playback two different audio streams simultaneously" and then doing some reassigning of front/rear settings in the Realtek Audio Manager (can't remember the details). But that doesn't seem to be working now - either the speakers play sounds or the headphones, not both at the same time. To pose the question differently, Windows plays the sounds on the "default device". I'd like to make both headphones and the speakers kind of like the default devices.

• SQL Server 2008 and SP1

  - by andrew007

  Hi, I have a server where I installed SQL Server 2008 and after I applied the SP1. Now, I want also to add the Analysis Services to this instance by using the "Add or remove features...". My questions are: Is it possible to add the Analysis Services on a server with SP1 already installed? How can I apply the SP1 also to the new Analysis Service feature? THANKS!

• After update, flash plugin playing video too fast or too slow

  - by John H

  Last night I did an update and reboot. After that, I couldn't reliably play any flash videos. They would either go too fast or stutter (as if they were buffering every 2 seconds). This occurs in both Firefox and Chrome, however I'll troubleshoot in Chrome because it's easier to enable/disable plugins at will. With PPAPI enabled (and npapi disabled), flash videos play at 1.5x speeds and audio is scrambled. With NPAPI enabled (and ppapi disabled), flash videos stutter and skip, despite showing a decent buffer. From one old thread, I went into pavucontrol and tried disabling the high def audio controller. I also tried disabling Totem plugin to no affect.

• How to join video files from terminal?

  - by Leon Vitanos

  I have tried avidemux2_cli, mencoder, ffmpeg, cat.. But this doesn't always work (With the most of the times the error is that the audio codec is not the same) Maybe i put wrong options in the commands. So the commands: cat Sample.avi rrr.avi > complete.avi ffmpeg -i Sample.avi -i output.avi -vcodec copy -acodec copy complete.avi mencoder -ovc lavc -oac copy Sample.avi rrr.avi -o complete.avi avidemux2_cli --audio-codec copy --video-codec copy --output-format avi --load Sample.avi -append output.avi --save video.avi The cat problem is that it doesn't show error but it doesn't work always..Like the complete.avi will be exactly the same with Sample.avi Fmmpeg does nothing. The complete.avi is always the same with Sample.avi Mencoder error: All files must have identical audio codec and format for -oac copy. So the complete.avi is the same with Sample.avi avidemux2_cli there is no error but the complete.avi is again the same with Sample.avi.. So to sum up, all complete.avi are the same with Sample.avi.. And the problem is that they don't have the same audio codec ( i quess ).. Any ideas?

• VGA monitor won't detect on NVIDIA Quadro NVS 4200M

  I am on a Dell Latitude E6420 and just installed 12.04. When I plug in my external monitor's VGA cable, the laptop doesn't detect any new monitor.

• Bluetooth headset A2DP works, HSP/HFP not (no sound/no mic)

  - by Stefan Armbruster

  My Philips SBH9001 headset pairs fine using Ubuntu 12.04. In the audio settings it's properly detected as A2DP device and as HSP/HFP device. Hardware: Thinkpad X230, Ubuntu 12.04 64bit, Kernel 3.6.0-030600rc3-generic (build from Ubuntu mainline repo), Bluetooth device is USB-Id 0a5c:21e6 from Broadcom, Headset is a Philips SBH9001. Note: Kernel 3.6 rc3 is used because of a fix for audio on the dockingstation that is not in any previous branches. Playing audio in A2DP works just fine out of the box, but when switching the headset to HSP/HSP mode there is no sound nor does the microphone work. When connecting the headset, /var/log/syslog shows: Aug 25 21:32:47 x230 bluetoothd[735]: Badly formated or unrecognized command: AT+CSRSF=1,1,1,1,1,7 Aug 25 21:32:49 x230 rtkit-daemon[1879]: Successfully made thread 17091 of process 14713 (n/a) owned by '1000' RT at priority 5.

• How do I get a rt2800usb wireless device working?

  - by Jii

  My brand new desktop running 13.04 has endless problems with wireless. Dozens of others are flooding forums with reports of the same problems. It worked fine for a few days, then there were a few days where it started having problems sometimes and working sometimes. Now it never works at all. I have 5+ devices all able to connect without any trouble at all, including iPhone, Android phone, 3DS, multiple game consoles, a laptop running windows 7, and even a second desktop machine running Ubuntu 12.04 sitting right behind the 13.04 machine. All other devices have full wireless bars displayed (strong signals). At any moment, one of the following is happening, and it changes randomly: Trying to connect forever, but never establishing a connection. Wireless icon constantly animating. Finds no wireless networks at all. (There are 12+ in range according to other devices.) Will not try to connect to the network. If I use the icon to connect, it will display "Disconnected" within a few seconds. Will continuously ask for the network password. Typing it in correctly does not help. Wireless is working fine. This happens sometimes. It can work for days at a time, or only 10 mins at a time. Various things that usually do nothing but sometimes fix the problem: Reboot. This has the best chance of helping, but it usually takes 5+ times. Disable/re-enable Wi-Fi using the wireless icon. Disable/re-enable Networking using the wireless icon. Use the icon to try and connect to a network (if found). Use the icon to open Edit Connections and delete my connection info, causing it to be recreated (once it's actually found again). Various things that seem to make no difference: Changing between using Linux headers in grub at bootup, between 3.10.0, 3.9.0, or 3.8.0. Move the wireless router very close to the desktop. Running sudo rfkill unblock all (I dunno what this is supposed to do.) I've used Ubuntu for 6 years and I've never had a problem with networking. Now I'm spending all my time reading through endless problem reports and trying all the answers. None of them have helped. I am doing this instead of getting work done, which is defeating the whole purpose of using Ubuntu. It's heartbreaking to be honest. In the current state of "no networks are showing up", here are outputs from the random things that other people are usually asked to run: lspic 00:00.0 Host bridge: Intel Corporation Haswell DRAM Controller (rev 06) 00:01.0 PCI bridge: Intel Corporation Haswell PCI Express x16 Controller (rev 06) 00:14.0 USB controller: Intel Corporation Lynx Point USB xHCI Host Controller (rev 04) 00:16.0 Communication controller: Intel Corporation Lynx Point MEI Controller #1 (rev 04) 00:19.0 Ethernet controller: Intel Corporation Ethernet Connection I217-V (rev 04) 00:1a.0 USB controller: Intel Corporation Lynx Point USB Enhanced Host Controller #2 (rev 04) 00:1b.0 Audio device: Intel Corporation Lynx Point High Definition Audio Controller (rev 04) 00:1c.0 PCI bridge: Intel Corporation Lynx Point PCI Express Root Port #1 (rev d4) 00:1c.2 PCI bridge: Intel Corporation 82801 PCI Bridge (rev d4) 00:1d.0 USB controller: Intel Corporation Lynx Point USB Enhanced Host Controller #1 (rev 04) 00:1f.0 ISA bridge: Intel Corporation Lynx Point LPC Controller (rev 04) 00:1f.2 SATA controller: Intel Corporation Lynx Point 6-port SATA Controller 1 [AHCI mode] (rev 04) 00:1f.3 SMBus: Intel Corporation Lynx Point SMBus Controller (rev 04) 01:00.0 VGA compatible controller: NVIDIA Corporation GF119 [GeForce GT 610] (rev a1) 01:00.1 Audio device: NVIDIA Corporation GF119 HDMI Audio Controller (rev a1) 03:00.0 PCI bridge: ASMedia Technology Inc.

It said to install gksu. I tried that, but of course, not having Internet, I didn't get the package. So instead I did: sudo gedit /etc/pm/power.d/wireless Which created the file. Here is the body: #!/bin/sh /sbin/iwconfig wlan0 power off I then rebooted. No change. I tried adding exit 0 to the bottom of the wireless file, and rebooted. No change. Please note that this is a desktop machine. I'm assuming power management is primarily for laptops, but the iwconfig does state that power management is on, so who knows. The recommended router changes I did not do, since the current router settings are (I think) required for some of the older devices I have, and because the current settings work on all my modern devices including Ubuntu 12.04 and Windows 7. I do appreciate the advice though, and I'll look into it when I have time. Anything else to try? Update #2 I booted into Ubuntu 12.04.3 from a dvd, and the same problems exist. I have a separate old desktop machine with 12.04 installed that has no wireless problems at all. So obviously the problem is wireless hardware compatibility in both 12.04.03 LTS and 13.04. Update #3 The same problems exist even when using a wired connection. I plugged an ethernet cable directly to the router and the network manager added an "Auto Ethernet" entry, but it cannot establish a connection to it. So the problem is not specific to wireless. Meanwhile, I purchased a Trendnet N300 wireless USB adapter, TEW-664UB. I plugged it in, but I have no idea how to get Ubuntu to try and use it. Can anyone tell me how? Can I download a package on another computer and copy the .deb over to do an install, etc? I'm installing windows 7 to double check that the internet connection works there and it's not just some magically faulty hardware. Thanks for your help.

• 12.04 No Sound - ALC888 / Radeon 3200HD

  - by Ross

  Evening all. I have a MSI U230 netbook, MV40 processor, 4Gb RAM with integrated ATI Radeon 3200HD grahics & an ALC888 codec integrated soundcard. It has HDMI out as well. I've tried a few distro's and have been around linux for a short time. I reckon I've settled on Ubuntu 12.04 (32bit) due to it doing pretty much everything I want it to. I'm working with a fresh install right now. I recently re-installed when I was going in circles trying to solve my problem before. I install Ubuntu and it works, except for the sound. I have tried things like reinstalling Alsa, editing my asound.conf file, installing HDA Verb and a few other things. Its at the point where I need to ask for help...

• Cannot copy MP3 files from a CD

  - by MountainX

  I purchased a set of spoken word audio CD's that have MP3 and FLAC audio files; I think they also play as regular audio CD's because I see a CDA directory and .cda files. But I'm only interested in playing the MP3 files by copying them to my phone. Dolphin file manager shows all the files on the CD. However, it will not copy any of them to my hard drive, which is what my goal is. Dolphin shows no error, but the copy progress is zero. Amarok will play the files but not easily. I only tried the flac files. To play a file, I click the file in Dolphin, then I have to cancel a job using KDE's notification system, then Amarok proceeds to copy the file to a tmp directory which takes a long time, then it finally plays. kb3 will rip the audio, but I would prefer to copy the files directly from the CD. Since Dolphin would not copy the files, I thought I would try the terminal, but I can't get that to work either. mount -t auto -o ro /dev/sr0 /mnt/temp that gives the error: wrong fs type, bad option, bad superblock, etc. I get the same error using -t iso9660 and -t udf. so I started troubleshooting: ~$ wodim --devices wodim: Overview of accessible drives (1 found) : ------------------------------------------------------------------------- 0 dev='/dev/sg1' rwrw-- : 'MATSHITA' 'DVD-RAM UJ8A0AS' ------------------------------------------------------------------------- /dev/sg1 is not a block device sudo file -s /dev/sr0 ERROR: cannot read /dev/sr0 (input/output error) sudo file -s /dev/sg1 just hangs How can I copy these files to my computer hard disk?

• Unable To Get Sound Working to External Speaker on HP TouchSmart 320 on 11.04 or 11.10

• System speakers not recognized

  - by Kyle Maxwell

  Since upgrading to Xubuntu 13.10, sound has not functioned properly (e.g. screeching when playing Skype notifications). Now, however, it does not function at all. pavucontrol only shows Dummy Output and does not recognize the built-in speakers on my Dell Precision M4600. Possibly related, the sound indicator applet does not come up when I click on it, only showing a small white bar underneath it. I have purged and reinstalled pulseaudio. lspci -v shows: 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 04) Subsystem: Dell Precision M4600 Flags: bus master, fast devsel, latency 0, IRQ 56 Memory at f2560000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel 01:00.1 Audio device: NVIDIA Corporation GF106 High Definition Audio Controller (rev a1) Subsystem: Dell Device 14a3 Flags: bus master, fast devsel, latency 0, IRQ 17 Memory at f0080000 (32-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel The "Capabilities: <access denied" line makes me wonder if there's a permissions issue, as the Log Out applet now shows "Restart" and "Shutdown" grayed out. groups shows me in: kmaxwell adm dialout cdrom sudo dip plugdev fuse lpadmin netdev sambashare vboxusers

• After upgrading to trusty, ALSA midi connection (aconnect) doesn't seem to work right

  - by SougonNaTakumi

  Previously in kubuntu 13.10 I was able to open vmpk or plug in a midi keyboard, and provided that TiMidity was running in server mode, I could run aconnect [keyboard port (129:0 for vmpk)] 14:0 aconnect 14:0 128:0 and I could play the keyboard and get sound. But now, a while after upgrading to trusty, I tried to do that, and didn't get any sound. TiMidity itself still plays files fine, but if I try to play them with aplaymidi, I still just get silence. Oddly, the midi files are clearly being read. When I ran (where 130:0 was vmpk's input port) aplaymidi -p 130:0 ~/path/to/midi.mid vmpk was highlighting notes on the piano as if it were playing the midi. One time I tried this, TiMidity (?) very briefly played a fraction of a second of the first chord of my song before everything went silent and vmpk just highlighted the first voice on the keyboard as usual. Now the weirdest part of this is that probably about 40% of the time, when I've played at least one note with either aplaymidi or vmpk, when I run aconnect -x I get a sudden burst of a note or chord from my speakers (that is, if I played one note, I get a note; if I played multiple sequential notes, they turn into a chord), as if the notes were being queued up but not being played and that somehow liberated them. I have no idea what's going on there. A little while ago I remember having a problem with Audacity playing wav files sped up and also locking up if I tried to pause it, which it stopped doing when I set the audio devices to the actual audio devices rather than pulse. But now when I checked again, it's doing the opposite: it won't play audio at all and/or acts weirdly if I don't set the audio devices to pulse, and either way will very occasionally randomly do the speeding up thing regardless. Oddly in the midst of what's looking like a pretty screwed up sound system, sound in VLC and Firefox has been working fine and if I play a wav file with aplay ~/path/to/sound.wav that works fine too. Any idea what I could do to figure out what's wrong with ALSA and/or fix it?

• What is the recommended MongoDB schema for this quiz-engine scenario?

  - by hughesdan

  I'm working on a quiz engine for learning a foreign language. The engine shows users four images simultaneously and then plays an audio file. The user has to match the audio to the correct image. Below is my MongoDB document structure. Each document consists of an image file reference and an array of references to audio files that match that image. To generate a quiz instance I select four documents at random, show the images and then play one audio file from the four documents at random. The next step in my application development is to decide on the best document schema for storing user guesses. There are several requirements to consider: I need to be able to report statistics at a user level. For example, total correct answers, total guesses, mean accuracy, etc) I need to be able to query images based on the user's learning progress. For example, select 4 documents where guess count is 10 and accuracy is <=0.50. The schema needs to be optimized for fast quiz generation. The schema must not cause future scaling issues vis a vis document size. Assume 1mm users who make an average of 1000 guesses. Given all of this as background information, what would be the recommended schema? For example, would you store each guess in the Image document or perhaps in a User document (not shown) or a new document collection created for logging guesses? Would you recommend logging the raw guess data or would you pre-compute statistics by incrementing counters within the relevant document? Schema for Image Collection: _id "505bcc7a45c978be24000005" date 2012-09-21 02:10:02 UTC imageFileName "BD3E134A-C7B3-4405-9004-ED573DF477FE-29879-0000395CF1091601" random 0.26997075392864645 user "2A8761E4-C13A-470E-A759-91432D61B6AF-25982-0000352D853511AF" audioFiles [ 0 { audioFileName "C3669719-9F0A-4EB5-A791-2C00486665ED-30305-000039A3FDA7DCD2" user "2A8761E4-C13A-470E-A759-91432D61B6AF-25982-0000352D853511AF" audioLanguage "English" date 2012-09-22 01:15:04 UTC } 1 { audioFileName "C3669719-9F0A-4EB5-A791-2C00486665ED-30305-000039A3FDA7DCD2" user "2A8761E4-C13A-470E-A759-91432D61B6AF-25982-0000352D853511AF" audioLanguage "Spanish" date 2012-09-22 01:17:04 UTC } ]

• How to make the internal subwoofer work on an Asus G73JW?

  - by CodyLoco

  I have an Asus G73JW laptop which has an internal subwoofer built-in. Currently, the system detects the internal speakers as a 2.0 system (or I can change do 4.0 is the only other option). I found a bug report here: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/673051 which discusses the bug and according to them a fix was sent upstream back at the end of 2010. I would have thought this would have made it into 12.04 but I guess not? I tried following the link given at the very bottom to install the latest ALSA drivers, here: https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules however I keep running into an error when trying to install: sudo apt-get install linux-alsa-driver-modules-$(uname -r) Reading package lists...

• Unreal Torunament (UT99) no sound in 12.04?

  - by Talas

  I've been trying to get sound working in Unreal Torunament for a couple of days now. I'm using the native Unreal Tournament version, not wine or something like that. I have sound in all other games and media applications that I have tried. In older ubuntu versions it worked fine. I'm now using kubuntu 12.04, I have all the alsa-oss and oss-compat packages installed. I have followed most of the advice out there, and it all seems to fall on padsp and aoss. My problem, however, is that even when trying to use padsp or aoss, I can't get any sound at all. (Note UT has two output modes: ALAudio and Generic(OSS), I have tried both). Is there some configuration required to use padsp or aoss correctly? I have ran it like padsp ./ut and aoss ./ut If using the AL backend in UT I get (both aoss and padsp give this): Bound to ALAudio.so open /dev/dsp: Invalid argument Audio initialization failed. If using the OSS backend in UT I get (both aoss and padsp give this): Bound to Audio.so Failed to open audio device. Audio initialization failed. Note that so far, I have gotten absolutely no sound. Thanks for any help!

• SQL SERVER – Maximize Database Performance with DB Optimizer – SQL in Sixty Seconds #054

  - by Pinal Dave

  Performance tuning is an interesting concept and everybody evaluates it differently. Every developer and DBA have different opinion about how one can do performance tuning. I personally believe performance tuning is a three step process Understanding the Query Identifying the Bottleneck Implementing the Fix While, we are working with large database application and it suddenly starts to slow down. We are all under stress about how we can get back the database back to normal speed. Most of the time we do not have enough time to do deep analysis of what is going wrong as well what will fix the problem. Our primary goal at that time is to just fix the database problem as fast as we can. However, here is one very important thing which we need to keep in our mind is that when we do quick fix, it should not create any further issue with other parts of the system. When time is essence and we want to do deep analysis of our system to give us the best solution we often tend to make mistakes. Sometimes we make mistakes as we do not have proper time to analysis the entire system. Here is what I do when I face such a situation – I take the help of DB Optimizer. It is a fantastic tool and does superlative performance tuning of the system. Everytime when I talk about performance tuning tool, the initial reaction of the people is that they do not want to try this as they believe it requires lots of the learning of the tool before they use it. It is absolutely not true with the case of the DB optimizer. It is a very easy to use and self intuitive tool. Once can get going with the product, in no time. Here is a quick video I have build where I demonstrate how we can identify what index is missing for query and how we can quickly create the index. Entire three steps of the query tuning are completed in less than 60 seconds. If you are into performance tuning and query optimization you should download DB Optimizer and give it a go. Let us see the same concept in following SQL in Sixty Seconds Video: You can Download DB Optimizer and reproduce the same Sixty Seconds experience.

• BigData and Customer Experience: Happy Together

  - by Isabel F. Peñuelas

  The two big buzzes of the year may lay closer than it appears. Both concepts intersect at various points: BigData and Return of Investment of Marketing Campaigns On a recent post Big Data Is The Future Of Marketing Jeff Dachis explains very clearly how “Big data analytics finally allows marketers to identify, measure, and manage what is positively impacting their Brand”. Regression analysis applied to big data volumes coming from social media will substitute the failed attempts to justify marketing investments on social media in terms of followers and likes, he continues, “the measurement models applied by marketers on TV Campaigns don´t work on social”, we need to study the data with fresh eyes and maybe then we will start understanding and measuring brand engagemet. Social CRM and BigData The real value of Social CRM start by analyzing mass of big data from social media in order of applying social intelligence techniques that allow us to classify new customer niches and communities and define appropriated strategies to contact potential customers. Gartner Says that the Market for Social CRM is on pace to surpass $1 Billion in Revenue by Year-End 2012 but in words of Zach Hofer-Shall, Analyst at Forrester Research “Social customer relationship management is hard” (The Social CRM Arms Race Heats ). To succeed brands need three things: Investing in new social tools, investing in consultancy and investing in infrastructure for massive data storage and analysis. Neither CeX or BigData are easy and cheap wins. But what are the customer benefits of such investments? Big Data and Brand Engagement Time is the most valuable asset of todays consumers: tired of information overload, exhausted by the terabytes of offering, anxious because of not having the same fast multichannel experience with their services’ marketers or preferred goods providers than the one they found on their social media. Yes, I know you have read this before- me too. But is real. The motto of the Customer Experience philosophy of providing a consistent experience through multiple touchpoints that makes the relationship customer/brand easier and valuable finds it basis on understanding customer/s preferences and context for which BigData analysis is another imperative. In summary, I believe that using BigData Analysis in combination with appropriated CeX strategies and technologies is a promising direction for achieving: efficiency and marketing cost-savings; growing the customer base; and increasing customer conversion and retention. In a world: The Direction of Future Marketing.

• MySQL and Hadoop Integration - Unlocking New Insight

  - by Mat Keep

  “Big Data” offers the potential for organizations to revolutionize their operations. With the volume of business data doubling every 1.2 years, analysts and business users are discovering very real benefits when integrating and analyzing data from multiple sources, enabling deeper insight into their customers, partners, and business processes. As the world’s most popular open source database, and the most deployed database in the web and cloud, MySQL is a key component of many big data platforms, with Hadoop vendors estimating 80% of deployments are integrated with MySQL. The new Guide to MySQL and Hadoop presents the tools enabling integration between the two data platforms, supporting the data lifecycle from acquisition and organisation to analysis and visualisation / decision, as shown in the figure below The Guide details each of these stages and the technologies supporting them: Acquire: Through new NoSQL APIs, MySQL is able to ingest high volume, high velocity data, without sacrificing ACID guarantees, thereby ensuring data quality. Real-time analytics can also be run against newly acquired data, enabling immediate business insight, before data is loaded into Hadoop. In addition, sensitive data can be pre-processed, for example healthcare or financial services records can be anonymized, before transfer to Hadoop. Organize: Data is transferred from MySQL tables to Hadoop using Apache Sqoop. With the MySQL Binlog (Binary Log) API, users can also invoke real-time change data capture processes to stream updates to HDFS. Analyze: Multi-structured data ingested from multiple sources is consolidated and processed within the Hadoop platform. Decide: The results of the analysis are loaded back to MySQL via Apache Sqoop where they inform real-time operational processes or provide source data for BI analytics tools. So how are companies taking advantage of this today? As an example, on-line retailers can use big data from their web properties to better understand site visitors’ activities, such as paths through the site, pages viewed, and comments posted. This knowledge can be combined with user profiles and purchasing history to gain a better understanding of customers, and the delivery of highly targeted offers. Of course, it is not just in the web that big data can make a difference. Every business activity can benefit, with other common use cases including: - Sentiment analysis; - Marketing campaign analysis; - Customer churn modeling; - Fraud detection; - Research and Development; - Risk Modeling; - And more. As the guide discusses, Big Data is promising a significant transformation of the way organizations leverage data to run their businesses. MySQL can be seamlessly integrated within a Big Data lifecycle, enabling the unification of multi-structured data into common data platforms, taking advantage of all new data sources and yielding more insight than was ever previously imaginable. Download the guide to MySQL and Hadoop integration to learn more. I'd also be interested in hearing about how you are integrating MySQL with Hadoop today, and your requirements for the future, so please use the comments on this blog to share your insights.

• #MDX in London and speculation about future books

  - by Marco Russo (SQLBI)

  Chris Webb, who wrote the Expert Cube Development with Microsoft SQL Server 2008 Analysis Services book with me and Alberto , is preparing another Introduction to MDX course in London, this time from October 26th to 28th. It is now a three day course (previously it was two day) and you can find every other detail here . You might be wondering whether we are writing something else... well, we don't have plan to release a new edition of the Analysis Services book - after all, all the content of the...(read more)

• Understanding Data Science: Recent Studies

  - by Joe Lamantia

  If you need such a deeper understanding of data science than Drew Conway's popular venn diagram model, or Josh Wills' tongue in cheek characterization, "Data Scientist (n.): Person who is better at statistics than any software engineer and better at software engineering than any statistician." two relatively recent studies are worth reading.   'Analyzing the Analyzers,' an O'Reilly e-book by Harlan Harris, Sean Patrick Murphy, and Marck Vaisman, suggests four distinct types of data scientists -- effectively personas, in a design sense -- based on analysis of self-identified skills among practitioners.  The scenario format dramatizes the different personas, making what could be a dry statistical readout of survey data more engaging.  The survey-only nature of the data,  the restriction of scope to just skills, and the suggested models of skill-profiles makes this feel like the sort of exercise that data scientists undertake as an every day task; collecting data, analyzing it using a mix of statistical techniques, and sharing the model that emerges from the data mining exercise.  That's not an indictment, simply an observation about the consistent feel of the effort as a product of data scientists, about data science.  And the paper 'Enterprise Data Analysis and Visualization: An Interview Study' by researchers Sean Kandel, Andreas Paepcke, Joseph Hellerstein, and Jeffery Heer considers data science within the larger context of industrial data analysis, examining analytical workflows, skills, and the challenges common to enterprise analysis efforts, and identifying three archetypes of data scientist.  As an interview-based study, the data the researchers collected is richer, and there's correspondingly greater depth in the synthesis.  The scope of the study included a broader set of roles than data scientist (enterprise analysts) and involved questions of workflow and organizational context for analytical efforts in general.  I'd suggest this is useful as a primer on analytical work and workers in enterprise settings for those who need a baseline understanding; it also offers some genuinely interesting nuggets for those already familiar with discovery work. We've undertaken a considerable amount of research into discovery, analytical work/ers, and data science over the past three years -- part of our programmatic approach to laying a foundation for product strategy and highlighting innovation opportunities -- and both studies complement and confirm much of the direct research into data science that we conducted. There were a few important differences in our findings, which I'll share and discuss in upcoming posts.
