  • VSDB to SSDT part 3 : command-line deployment with SqlPackage.exe, replacement for Vsdbcmd.exe

    - by Etienne Giust
    For our continuous integration needs, we use a powershell script to handle deployment. A simpler approach would be to have a deployment task embedded within the build process. See the solution provided here by Jakob Ehn (a most interesting read which also dives into the '”deploying from Visual Studio” specifics) : http://geekswithblogs.net/jakob/archive/2012/04/25/deploying-ssdt-projects-with-tfs-build.aspx   For our needs, though, clearly separating our build phase from our deployment phase is important. It allows us to instantly deploy old versions. Also it is more convenient for continuous integration. So we stick with the powershell script approach. With VSDB projects, that script used to call the following command (the vsdbcmd executable was locally available, along with needed libraries): vsdbcmd.exe /a:Deploy /dd /cs:<CONNECTIONSTRING TO TARGET DB> /dsp:SQL /manifest:< PATH TO .deploymanifest FILE>   To be able to do the approximately same thing with a SSDT produced file (dacpac), you would call this command on a machine which has VS2012 installed (or the SSDT installed, see here : http://msdn.microsoft.com/en-us/library/hh500335%28v=vs.103%29):   C:\Program Files (x86)\Microsoft SQL Server\110\DAC\bin\SqlPackage.exe /Action:Publish /SourceFile:<PATH TO Database.dacpac FILE> /Profile:<PATH TO .publish.xml FILE>   And from within a powershell script :   & "C:\Program Files (x86)\Microsoft SQL Server\110\DAC\bin\SqlPackage.exe" /Action:Publish /SourceFile:<PATH TO Database.dacpac FILE> /Profile:<PATH TO .publish.xml FILE>   The command will consume a publish.xml file where the connection string and the deployment options are specified. You must be familiar with it if you have done some deployments from visual studio. If not, please refer to the above mentioned article by Jakob Ehn.   It is also possible to pass those parameters in the command line. The complete SqlPackage.exe syntax is detailed here : http://msdn.microsoft.com/en-us/library/hh550080%28v=vs.103%29.aspx

  • External microphone not working

    - by haireefairee
    gnome-volume-control does not recognise external hardware. My headphones work nonetheless, but an external microphone does not. External microphones used to work, but at times were temperamental - I would have to login or logout with or without microphone plugged in. I am running Ubuntu 10.04 LTS (Lucid Lynx) on an mSi U100 wind notebook with one Intel soundcard and trying to use a jack microphone which has worked previously. USB microphones have also been problematic. I have done the basics: Installed upgrades. Checked nothing is muted. Looked for the device on gnome-volume-control. Tried using a different microphone that works on a friends computer. Tested my microphone works when using a different computer. Checked my soundcard can be seen (cat /proc/asound/cards). I have done more complicated things: I have tried playing around with settings in alsamixer. Nothing is muted. I can adjust "mic" and "internal mic" regardless of whether an external microphone is plugged in. I have the choice of input source from "mic", "front mic", "line" and "CD". I've played around changing this and it hasn't helped. I only have one CAPTURE option. In gnome-sound-recorder I have the choice of line, microphone 1 and microphone 2. I have played around changing this option. None of these pick up sound from the external microphone. Microphone 2 is the microphone on my laptop which is bad quality. In gnome-sound-recorder I have the choice of different profiles, and changing this has not helped either. I have looked at gstreamer-properties but none of that seemed helpful. I don't know if there a way to check if these external devices are being picked up. I would like to make an external microphone work. Please help!

  • Dell Latitude will not boot after fresh Ubuntu 12.10 installation. Black screen

    - by James
    I have an old dell latitude d610 that I've just installed ubuntu 12.10 onto, and now unfortunately it will not complete booting up. The screen flashes purple but then fades out and dies. I'm fairly sure there is an issue with graphics drivers, as I had to turn on "nomodeset" in the options when installing off a DVD to see the installer, but I'm very new to linux and don't know terribly much at all apart from what I've read on the net. I have been able to hold down shift and bring up GRUB, and entered into recovery mode, and when I enter into the low graphics mode, the xserver log file says it can detect a screen but found none with a useable configuration, then goes on to say a fatal server error has occurred and no screen have been found at all, telling me to check a log file at "/var/log/xorg.0.log" I have no idea how to check this specific log file! Attempting to actually go further than this in low graphics mode and restart the display simply artefacts the screen. It is all very strange and annoying because I did once by random have the machine boot completely for no apparent reason, but upon restarting the issue reoccurred.

  • What You Said: Your Favorite Co-Op Games

    - by Jason Fitzpatrick
    While competitive gaming is fun, reader response to this week’s Ask the Readers question shows that good old beat-the-bad-guys-together cooperative gaming is as popular as ever. Read on to see what your fellow readers are playing. By far the most popular nomination for favorite co-op game was an outright classic: 1987′s smash hit Contra. Originally released as an arcade game, it was ported to the Nintendo Entertainment System in 1988. Contra was groundbreaking for the time as it featured simultaneous play for the two players–you and a friend could play side by side without waiting to take your turn. Clearly that kind of side-by-side play resonated with readers. RJ writes: When my fiance and I played and beat Contra on the NES. I knew she was the one and we got married and its been great. That’s no small feat; Contra was voted “Toughest Game to Beat” by IGN.com readers. Even readers who had moved on to newer games still recall Contra fondly; Jami writes: The Gears of War trilogy on 360 is my favorite co-op currently, although I do have fond memories of bonding with my brother playing some co-op Contra on the NES.

  • Problem with SNMP and MIBs

    - by jap1968
    I am installing Zabbix to monitor via snmp some devices from a machine running Ubuntu 12.04 server. There is a problem with MIB definitions, since snmp commands do no properly translate some of the MIBs. I have already installed the "snmp-mibs-downloader" package, so the files containing the MIB descriptions are properly installed. The MIB are only translated to obtain the numeric key (the MIB files are accessible to the snmp commands), but the results returned by the snmpget command do not properly translate the key. The zabbix templates that I am using do expect the key translated (SNMPv2-MIB::sysUpTime.0) , so, the current results are not recognised and these are ignored. Test case: $ snmptranslate -On SNMPv2-MIB::sysUpTime.0 .1.3.6.1.2.1.1.3.0 $ snmpget -v 2c -c public 192.168.1.1 1.3.6.1.2.1.1.3.0 iso.3.6.1.2.1.1.3.0 = Timeticks: (2911822510) 337 days, 0:23:45.10 On another machine (running a very old Red Hat based distribution), the snmp commands perform both, the directe and reverse traslation, as expected: # snmptranslate -On SNMPv2-MIB::sysUpTime.0 .1.3.6.1.2.1.1.3.0 # snmpget -v 2c -c public 192.168.1.1 1.3.6.1.2.1.1.3.0 SNMPv2-MIB::sysUpTime.0 = Timeticks: (2911819485) 337 days, 0:23:14.85 What is the problem on my Ubuntu box? Is there something I am missing?

  • deWitters Game loop in libgdx(Android)

    - by jaysingh
    I am a beginner and I want a complete example in LibGDX for android(Fixed time game loop) how to limit the framerate to 50 or 60. Also how to mangae interpolation between game state with simple example code e.g. deWiTTERS Game Loop: @Override public void render() { float deltaTime = Gdx.graphics.getDeltaTime(); Update(deltaTime); Render(deltaTime); } libgdx comments:- There is a Gdx.graphics.setVsync() method (generic = backend-independant), but it is not present in 0.9.1, only in the Nightlies. "Relying on vsync for fixed time steps is a REALLY bad idea. It will break on almost all hardware out there. See LwjglApplicationConfiguration, there's a flag in there that let s use toggle gpu/software vsynching. Play around with it." (Mario) NOTE that none of these limit the framerate to a specific value... if you REALLY need to limit the framerate for some reason, you'll have to handle it yourself by returning from render calls if xxx ms haven't passed since the last render call. li

  • Switching to a career in Machine Learning

    - by Naive Machine Learner
    My day job is plain old software development. I am also doing my Masters in CS (part time, course based). I took a course on AI and found machine learning quite fascinating but like most courses it only offered a basic intro. I intend to learn more about Machine Learning and if possible get a job in that field. When I look at job postings in this field it is clear that a Phd in Machine learning (or prior experience in the field with considerable expertise) is required for most of them. I'm looking for advice on self learning to gain experience that'll useful in industry. At least, enough experience to get my foot in. I will do the obvious ones like reading text books, papers etc. Perhaps any open source efforts that I can participate in or something I could do on my own? Apologies if I'm being vague here but I hope there are at least a few of you who done a similar switch and can advise. Thanks !

  • I'm scared for my technical phone interview for an internship!

    - by Marie
    [EDIT 2.0 ]Hello everyone. This is my second phone interview for a development internship. My very first one was okay, but I didn't get my dream internship. Now, I'm facing fears about this upcoming interview. My fears include the following: I'm 19 years old. The thought of 2 lead developers interviewing me makes me think that I'll know so little of what they'd want me to know. Like they will expect so much. I'm a junior having these panic attacks that I did not get in the other internship. I have a little voice saying "You didn't get the other one. What makes you think you'll get this one?". I'm scared that I'll freeze up, forget everything I know, and stutter like an idiot. I'm still traumatized by the last one, because I really really wanted that internship, and I even studied very hard for it. When I was in the interview, I was so nervous I couldn't think clearly. As a result, I didn't do as well as I know I could have. The minute I hung up, I even thought of a better solution to the interview question! Any tips for a soon-to-be intern (hopefully!)? Thank you! P.S. I'm preparing by using this guide for phone interviews.

    - by MarkPearl
    Learning Outcomes Name different device categories Discuss the functions and structure of I/.O modules Describe the principles of Programmed I/O Describe the principles of Interrupt-driven I/O Describe the principles of DMA Discuss the evolution characteristic of I/O channels Describe different types of I/O interface Explain the principles of point-to-point and multipoint configurations Discuss the way in which a FireWire serial bus functions Discuss the principles of InfiniBand architecture External Devices An external device attaches to the computer by a link to an I/O module. The link is used to exchange control, status, and data between the I/O module and the external device. External devices can be classified into 3 categories… Human readable – e.g. video display Machine readable – e.g. magnetic disk Communications – e.g. wifi card I/O Modules An I/O module has two major functions… Interface to the processor and memory via the system bus or central switch Interface to one or more peripheral devices by tailored data links Module Functions The major functions or requirements for an I/O module fall into the following categories… Control and timing Processor communication Device communication Data buffering Error detection I/O function includes a control and timing requirement, to coordinate the flow of traffic between internal resources and external devices. Processor communication involves the following… Command decoding Data Status reporting Address recognition The I/O device must be able to perform device communication. This communication involves commands, status information, and data. An essential task of an I/O module is data buffering due to the relative slow speeds of most external devices. An I/O module is often responsible for error detection and for subsequently reporting errors to the processor. I/O Module Structure An I/O module functions to allow the processor to view a wide range of devices in a simple minded way. The I/O module may hide the details of timing, formats, and the electro mechanics of an external device so that the processor can function in terms of simple reads and write commands. An I/O channel/processor is an I/O module that takes on most of the detailed processing burden, presenting a high-level interface to the processor. There are 3 techniques are possible for I/O operations Programmed I/O Interrupt[t I/O DMA Access Programmed I/O When a processor is executing a program and encounters an instruction relating to I/O it executes that instruction by issuing a command to the appropriate I/O module. With programmed I/O, the I/O module will perform the requested action and then set the appropriate bits in the I/O status register. The I/O module takes no further actions to alert the processor. I/O Commands To execute an I/O related instruction, the processor issues an address, specifying the particular I/O module and external device, and an I/O command. There are four types of I/O commands that an I/O module may receive when it is addressed by a processor… Control – used to activate a peripheral and tell it what to do Test – Used to test various status conditions associated with an I/O module and its peripherals Read – Causes the I/O module to obtain an item of data from the peripheral and place it in an internal buffer Write – Causes the I/O module to take an item of data form the data bus and subsequently transmit that data item to the peripheral The main disadvantage of this technique is it is a time consuming process that keeps the processor busy needlessly I/O Instructions With programmed I/O there is a close correspondence between the I/O related instructions that the processor fetches from memory and the I/O commands that the processor issues to an I/O module to execute the instructions. Typically there will be many I/O devices connected through I/O modules to the system – each device is given a unique identifier or address – when the processor issues an I/O command, the command contains the address of the address of the desired device, thus each I/O module must interpret the address lines to determine if the command is for itself. When the processor, main memory and I/O share a common bus, two modes of addressing are possible… Memory mapped I/O Isolated I/O (for a detailed explanation read page 245 of book) The advantage of memory mapped I/O over isolated I/O is that it has a large repertoire of instructions that can be used, allowing more efficient programming. The disadvantage of memory mapped I/O over isolated I/O is that valuable memory address space is sued up. Interrupts driven I/O Interrupt driven I/O works as follows… The processor issues an I/O command to a module and then goes on to do some other useful work The I/O module will then interrupts the processor to request service when is is ready to exchange data with the processor The processor then executes the data transfer and then resumes its former processing Interrupt Processing The occurrence of an interrupt triggers a number of events, both in the processor hardware and in software. When an I/O device completes an I/O operations the following sequence of hardware events occurs… The device issues an interrupt signal to the processor The processor finishes execution of the current instruction before responding to the interrupt The processor tests for an interrupt – determines that there is one – and sends an acknowledgement signal to the device that issues the interrupt. The acknowledgement allows the device to remove its interrupt signal The processor now needs to prepare to transfer control to the interrupt routine. To begin, it needs to save information needed to resume the current program at the point of interrupt. The minimum information required is the status of the processor and the location of the next instruction to be executed. The processor now loads the program counter with the entry location of the interrupt-handling program that will respond to this interrupt. It also saves the values of the process registers because the Interrupt operation may modify these The interrupt handler processes the interrupt – this includes examination of status information relating to the I/O operation or other event that caused an interrupt When interrupt processing is complete, the saved register values are retrieved from the stack and restored to the registers Finally, the PSW and program counter values from the stack are restored. Design Issues Two design issues arise in implementing interrupt I/O Because there will be multiple I/O modules, how does the processor determine which device issued the interrupt? If multiple interrupts have occurred, how does the processor decide which one to process? Addressing device recognition, 4 general categories of techniques are in common use… Multiple interrupt lines Software poll Daisy chain Bus arbitration For a detailed explanation of these approaches read page 250 of the textbook. Interrupt driven I/O while more efficient than simple programmed I/O still requires the active intervention of the processor to transfer data between memory and an I/O module, and any data transfer must traverse a path through the processor. Thus is suffers from two inherent drawbacks… The I/O transfer rate is limited by the speed with which the processor can test and service a device The processor is tied up in managing an I/O transfer; a number of instructions must be executed for each I/O transfer Direct Memory Access When large volumes of data are to be moved, an efficient technique is direct memory access (DMA) DMA Function DMA involves an additional module on the system bus. The DMA module is capable of mimicking the processor and taking over control of the system from the processor. It needs to do this to transfer data to and from memory over the system bus. DMA must the bus only when the processor does not need it, or it must force the processor to suspend operation temporarily (most common – referred to as cycle stealing). When the processor wishes to read or write a block of data, it issues a command to the DMA module by sending to the DMA module the following information… Whether a read or write is requested using the read or write control line between the processor and the DMA module The address of the I/O device involved, communicated on the data lines The starting location in memory to read from or write to, communicated on the data lines and stored by the DMA module in its address register The number of words to be read or written, communicated via the data lines and stored in the data count register The processor then continues with other work, it delegates the I/O operation to the DMA module which transfers the entire block of data, one word at a time, directly to or from memory without going through the processor. When the transfer is complete, the DMA module sends an interrupt signal to the processor, this the processor is involved only at the beginning and end of the transfer. I/O Channels and Processors Characteristics of I/O Channels As one proceeds along the evolutionary path, more and more of the I/O function is performed without CPU involvement. The I/O channel represents an extension of the DMA concept. An I/O channel ahs the ability to execute I/O instructions, which gives it complete control over I/O operations. In a computer system with such devices, the CPU does not execute I/O instructions – such instructions are stored in main memory to be executed by a special purpose processor in the I/O channel itself. Two types of I/O channels are common A selector channel controls multiple high-speed devices. A multiplexor channel can handle I/O with multiple characters as fast as possible to multiple devices. The external interface: FireWire and InfiniBand Types of Interfaces One major characteristic of the interface is whether it is serial or parallel parallel interface – there are multiple lines connecting the I/O module and the peripheral, and multiple bits are transferred simultaneously serial interface – there is only one line used to transmit data, and bits must be transmitted one at a time With new generation serial interfaces, parallel interfaces are becoming less common. In either case, the I/O module must engage in a dialogue with the peripheral. In general terms the dialog may look as follows… The I/O module sends a control signal requesting permission to send data The peripheral acknowledges the request The I/O module transfers data The peripheral acknowledges receipt of data For a detailed explanation of FireWire and InfiniBand technology read page 264 – 270 of the textbook

  • Exalogic&ndash;The One Day Installation Challenge

    - by james.bayer
    It’s a really exciting time for the extended WebLogic community as we are enjoying seeing the impressive results of Exalogic deployments.  At Oracle Open World, a lot of people I spoke with came away impressed with the raw performance.  However, Exalogic offers a lot more than just raw performance.  I had the pleasure of working with Ram Sivaram during one of the Exalogic training sessions in Santa Clara.  In this video diary, he shows the Exalogic machine arrive on the shipping dock, get unpacked, wired up, powered on, configured, and installed with a WebLogic Server cluster in just about 10 hours.  I’ve worked with customers in the past that have taken several weeks or longer to get an environment ready after the hardware arrives.  This typically involves many different specialized teams in their organization.  Mohamad Afshar just wrote a great explanation of the benefit of Engineered Systems and contrasting that to the status quo.  Being able to streamline deployment of middleware capacity will have a lot of value for customers shortening time to deployment.  Thanks for the video Ram, you’ve set a high bar, we’ll see if anyone can top your time!

  • DTLoggedExec 1.0 Stable Released!

    - by Davide Mauri
    After serveral years of development I’ve finally released the first non-beta version of DTLoggedExec! I’m now very confident that the product is stable and solid and has all the feature that are important to have (at least for me). DTLoggedExec 1.0 http://dtloggedexec.codeplex.com/releases/view/44689 Here’s the release notes: FIRST NON-BETA RELEASE! :) Code cleaned up Added SetPackageInfo method to ILogProvider interface to make easier future improvements Deprecated the arguments 'ProfileDataFlow', 'ProfilePath', 'ProfileFileName' Added the new argument 'ProfileDataFlowFileName' that replaces the old 'ProfileDataFlow', 'ProfilePath', 'ProfileFileName' arguments Updated database scripts to support new reports Split releases in three different packages for easier maintenance and updates: DTLoggedExec Executable, Samples & Reports Fixed Issue #25738 (http://dtloggedexec.codeplex.com/WorkItem/View.aspx?WorkItemId=25738) Fixed Issue #26479 (http://dtloggedexec.codeplex.com/WorkItem/View.aspx?WorkItemId=26479) To make things easier to maintain I’ve divided the original package in three different releases. One is the DTLoggedExec executable; samples and reports are now available in separate packages so that I can update them more frequently without having to touch the engine. Source code of everything is available through Source Code Control: http://dtloggedexec.codeplex.com/SourceControl/list/changesets As usual, comments and feebacks are more than welcome! (Just use Codeplex, please, so it will be easier for me to keep track of requests and issues) Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • How to start a task before networking?

    - by user1252434
    I've written an upstart task that modifies /etc/network/interfaces. (Actually a file sourced into it.) Which start on condition do I need to declare to let my task run before any networking jobs? I've tried start on starting networking, but that's apparently too late. When I log in after booting I can see that the changes were written, but obviously they are not used: the new config states a static IP, but the boot process waits for a non-existing DHCP server (old config) to time out. I've also tried start on starting network-interface INTERFACE=eth0, which didn't work either. IIRC there was an error in the log that the change couldn't be written. Background: I need a VM template that can be cloned and the clones configured through a script. Among other settings, I need to give them a static IP address to access them from the host. I use guestfish to write a config file to one of the virtual disks and let a script apply these settings to the system. I don't want that disk to contain an actual system settings file. I can't modify /etc directly, because that disk is shared (copy-on-write/diff) among the clones and guestfish apparently doesn't support that type of image. I could also let them use DHCP and setup a server that assigns IP by MAC, but I'm afraid of the complexity. I could also add just another virtual disk for configuration files, but if possible I'd prefer to store settings directly on the system disk image. Used software: Ubuntu Server 12.04, VirtualBox. The configuration modifier is a self written ruby script.

  • Using JavaScript for basic HTML layout

    - by Slobaum
    I've been doing HTML layout as well as programming for many years and I'm seeing a growing issue recently. Folks who primarily do HTML layout are becoming increasingly more comfortable using JavaScript to solve basic page layout problems. Rather than consider what HTML is capable of doing (to hit their target browsers), they're slapping on bloated JS frameworks that "fix" fairly basic problems. Let's get this out of the way right here: I find this practice annoying and often inconsiderate of those with special accessibility needs. Unfortunately, when you try to tell these folks that what they're doing isn't semantic, ideal, or possibly even a good idea, they always counter with the same old arguments: "JavaScript has a market saturation of 98%, we don't care about the other 2%." or "Who doesn't have JavaScript enabled these days?" or simply "We don't care about those users." I find that remarkably short-sighted. I would really like the opinion of the community at large. What do you think, am I holding too fast to a dying ideal? I am willing to accept that, but would like to be given good arguments as to why I should disregard 2%+ of my user base (among others). Is JavaScript's prevalence a good excuse to use a programmatic language to do basic layout, thus mucking up your behavior and layout? jQuery and similar "behavior" based frameworks are blurring the lines, especially for those who don't realize the difference. Honestly (and probably most importantly), I would like some "argument ammo" to use against these folks when the "it's the right way to do it" argument is unacceptable. Can you cite sources outlining your stance, please? Thanks everybody, please be civil :)

  • Fix Google Reader Lag by Blocking Google Plus Button

    - by Jason Fitzpatrick
    Chrome: Many Google Reader fans have noticed, since the upgrades last month, that the service is unbearably slow. Speed things up by blocking the Google Plus button. Ever since the upgrade from the old Google Reader interface to the new integrated-with-Google-Plus interface, many Google Reader users were reporting a painfully long lag between reading entries in Reader. Previously hitting a keyboard shortcut or arrow button to move you through the new stories was instant with no noticeable lag. After the upgrade a lag of 3-5 seconds per individual story became common (we experienced this annoying lag around the How-To Geek office immediately after the upgrade). One of the theories was that the addition of the Google Plus button to every article was causing memory issues. Geeks Are Sexy tested the theory by blocking this address: plusone.google.com/u/0/_/+1/fastbutton using AdBlock. While people were reporting great success with that move (and you may find it works great too) we didn’t have any luck. What did work for us was installing Chromeblock and, while visiting reader.google.com, clicking on the ChromeBlock toolbar button and blocking Google +1. After that the 3-5 second lag vanished and browsing articles was as snappy as it had been. Hit up the link below to grab a copy of Chromeblock.

  • hdmi AC-3 audio broke after upgrading from 11.10 to 12.04.3

    - by Jim LastName
    I just updated my MythBuntu 11.10 to 12.04.3. Now, when I try to play 5.1 content (ripped DVD), my TV (and receiver) plays a "chattering" sound. I check my receiver and the digital dolby light isn't on--it's in PCM mode. So, either the audio is getting sent as AC-3, but the TV and receiver think it's PCM or the AC-3 audio got converted to multichannel PCM and they can't handle it. My setup: hdmi cable from htpc to TV. TV has an s/pdif output to my receiver. I know TV sends AC-3 audio out correctly because I see digital dolby light come on when I view a digital TV channel and PCM come on when I view an old analog channel. I can connect s/pdif from my htpc to my receiver and the digital dolby light comes on and it can decode the audio just fine. It's just not sending it right over hdmi. Now for some hints to the issue: I noticed in MythTV audio setup when I select alsa:hdmi.... the description only lists 2 channel PCM audio capability. speaker-test -Dhdmi:PCH -c6 errors about a bad channel count (only -c2 works). Finally, I tried vlc and it does the same chattering sound. These all make me think this isn't a MythTV issue, it's something lower than that. I think the best way to troubleshoot this is to start at the drivers and check each layer, one at a time all the way to alsa. I just don't know what the layers are and how to do it. So, I need to find some audio troubleshooting guide to assist me. Or, if one doesn't exist, I'd appreciate some steps. Thanks much, Jim

  • Algorithm for a lucky game [on hold]

    - by Ronnie
    Assume we have the following Keno(lottery type) game: From 80 numbers(from 1 to 80), 20 are being drawn. The players choose 1 or 2 or 3..... or 12 numbers to play(12 categories). If they choose for example 4 then they win if they predict correctly a certain amount of numbers(2,3 or 4) from the 4 they have played and lose if the predict only 1 or 0 numbers. They win X times their money accordingly to some predefined factor depending on how many numbers they predict from each category. The same with the other categories. And e.g 11 out of 11 gives 250000 times your money and 12 out of 12 gives 1000000 your money. So the company would want to avoid winnings so high. Every draw by the company is being made every 5 minutes and in each draw around 120000 (let's say) different predictions(Keno tickets) are being played. Let's assume 12000 are being played in category 10 and 12000 in category 11 and also 12000 in category 12. I'm wondering if there is an algorithm to allow the company that provides the game in the 5 minutes between the drawings, to find a 20 number set, in order to avoid any "12 out of 12" and "11 out of 11" and "11 out of 12" and "10 out of 11" and "10 out of 10" winning ticket. That means is there any algorithm, where in a time of less than 1 minute approximately(in todays hardware), to be able to find a 20 number set so that none of the 12000 12 and 11 and 10 number sets that the players played(in categories 10,11 and 12) contains any winning of "12 out of 12" and "11 out of 11" and "11 out of 12" and "10 out of 11" and "10 out of 10"? Or even better the generalization of the problem: What is the best algorithm(from a perspective of minimal time), to be able to find a Y number set from numbers 1 to Z(e.g Y=20, Z=80) so that none of the X sets of K-numbers that are being played(in category K) contains more than K-m numbers from the Y-set? (Note that for Y=K and m=1 there is a practical algorithm.)

  • The Social Business Thought Leaders - Steve Denning

    - by kellsey.ruppel
    How is the average organization doing? Not very well according to a number of recent books and reports. A few indicators provide quite a gloomy picture: Return on assets and invested capitals dropped to 25% of its value in 1965 in the entire US market (see The Shift Index by John Hagel) Firms are dying faster and faster with the average lifespan of companies listed in the S&P 500 index gone from 67 years in the 1920s to 15 years today (see Creative Disruption by Richard Foster) Employee engagement ratio, a high level indicator of an organization’s health proved to affect performance outcomes, does not exceed on average 20%-30% (see Employee Engagement, Gallup or The Engagement Gap, Towers Perrin) In one of the most enjoyable keynotes of the Social Business Forum 2012, Steve Denning (Author of Radical Management and Independent Management Consultant) explained why this is happening and especially what leaders should do to reverse the worrying trends. In this Social Business Thought Leaders series, we asked Steve to collapse some key suggestions in a 2 minutes video that we strongly recommend. Steve discusses traditional management - that set of principles and practices born in the early 20th century and largely inspired by thinkers such as Frederick Taylor and Henry Ford - as the main responsible for the declining performance of modern organizations. While so many things have changed in the last 100 or so years, most companies are in fact still primarily focused on maximizing profits and efficiency, cutting costs, coordinating individuals top-down through command and control. The issue is, in a knowledge intensive, customer centred, turbulent market like the one we are experiencing, similar concepts are not just alienating employees' passion but also destroying the last source of competitive differentiation left: creativity and the innovative potential. According to Steve Denning, in a phase change from old industrial to a creative, collaborative, knowledge economy, the answer is hidden in a whole new business ecosystem that puts the individual (both the employee and the customer) at the center of the organization. He calls this new paradigm Radical Management and in the video interview he articulates the huge challenges and amazing rewards our enterprises are facing during this inevitable transition.
