  • PASS: SQLRally Thoughts

    - by Bill Graziano
    The PASS Board recently decided that we wouldn’t put another US-based SQLRally on the calendar until we had a chance to review the program. I wanted to provide some of my thinking around this. Keep in mind that this is the opinion of one Board member. The Board committed to complete two SQLRally events to determine if an event modeled between SQL Saturday and the Summit was viable. We’ve completed the two events and now it’s time to step back and review the program. This is my seventh year on the PASS Board. Over that time people have asked me why PASS does certain things. Many, many times my answer has been “Because that’s the way we did it last year”. And I am tired of giving that answer. We need to take a step back and review the US-based SQLRally before we schedule another one. It would be irresponsible for me as a Board member to commit resources to this without validating that what we’re doing makes sense for the organization and our members. I have no doubt that this was a great event for the attendees. We just need to validate it’s the best use of our resources. Please keep in mind that we haven’t cancelled the event. We’ve just said we need to review it before scheduling another one. My opinion is that some fairly serious changes are needed to the model before we consider it again – IF we do it again. I’ve come to that conclusion after speaking with the Dallas organizers, our HQ team, our Marketing team, other Board members (including one of the Orlando organizers), attendees in Orlando and Dallas and visiting other similar events. I should point out that their views aren’t unanimous on nearly any part of this event -- which is one of the reasons I want to take some time and think about this before continuing. I think it’s helpful to look at the original goals of what we were trying to accomplish. Andy Warren wrote these up in August of 2010. My summary of these goals and some thoughts on each one is below. Many of these thoughts revolve around the growth of SQL Saturdays. In the two years since that document was written these events have grown significantly. The largest SQL Saturdays are now over 500 people which mean they are nearly the same size as our recent SQLRally. Our goals included: Geographic diversity. We wanted an event in an area of the country that was away from any given Summit location. I think that’s still a valid goal. But we also have SQL Saturdays all over the country. What does SQLRally bring to this that SQLSaturday doesn’t? Speaker growth. One of the stated goals was to build a “farm club” for speakers. This gives us a way for speakers to work up to speaking at Summit by speaking in front of larger crowds. What does SQLRally bring to this that the larger SQL Saturdays aren’t providing? Pre-Conference speakers is one obvious answer here. Lower price. On a per-day basis, SQLRally is roughly 1/4th the price of the Summit. We wanted a way for people to experience something Summit-like at a lower price point. The challenge is that we are very budget constrained at that lower price point. International Event Model.  (I need to write more about this but I’m out of time.  I’ll cover it in the next installment.) There are a number of things I really like about SQLRally. I love the smaller conferences. They give me a chance to meet more people than at something the size of Summit. I like the two day format. That gives you two evenings to be at social events with people. Seeing someone a second day is a great way to build a bond with that person. That’s more difficult to do at a SQL Saturday. We also need to talk about the financial aspects of the event. Last year generated a small $17,000 profit on revenues of $200,000. Percentage-wise that’s reasonable but on an absolute basis it’s not a huge amount in our budget. We think this year will lose between $30,000 and $50,000 and take roughly 1,000 hours of HQ time. We don’t have detailed financials back yet but that’s our best guess at this point. Part of that was driven by using a convention center instead of a hotel. Until we get detailed financials back we won’t have the full picture around the financial impact. This event also takes time and mindshare from our Marketing team. This may sound like a small thing but please don’t underestimate it. Our original vision for this was something that would take very little time from our Marketing team and just a few mentions in the Connector. It turned out to need more than that. And all those mentions and emails take up space we could use to talk about other events and other programs. Last I wanted to talk about some of the things I’m thinking about. I don’t think it’s as simple as saying if we just fix “X” it all gets better. Is this that much better of an event than SQL Saturdays? What if we gave a few SQL Saturdays some extra resources? When SQL Saturdays were around 250 people that wasn’t as viable. With some of those events over 500 we need to reconsider this. We need to get back to a hotel venue. That will help with cost and networking. Is this the best use of the 1,000 HQ hours that we invested in the event? Is our price-point correct? I’m leaning toward raising our price closer to Summit on a per-day basis. I think this will let us put on a higher quality event and alleviate much of the budget pressure. Should growing speakers be a focus? Having top-line pre-conference speakers helps market the event. It will also have an impact on pricing and overall profit. We should also ask if it actually does grow speakers. How many of these people will eventually register for Summit? Attend chapters? Is SQLRally a driver into PASS or is it something that chapters, etc. drive people to? Should we have one paid day and one free instead of two paid days? This is a very interesting model that is used by SQLBits in the UK. This gives you the two day aspect as well as offering options for paid and free attendees. I’m very intrigued by this. Should we focus on a topic? Buried in the minutes is a discussion of whether PASS should have a Business Analytics conference separate from Summit. This is an interesting question to consider. Would making SQLRally be focused on a particular topic make it more attractive? Would that even be a SQLRally? Can PASS effectively manage the two events? (FYI - Probably not.) Would it help differentiate it from Summit and SQL Saturday? These are all questions that I think should be asked and answered before we do this event again. And we can’t do that if we don’t take time to have the discussion. I wanted to get this published before I take off for a few days of vacation. When I get back I’d like to write more about why the international events are different and talk about where we go from here.

  • Thinking in DAX (#powerpivot and #bism)

    - by Marco Russo (SQLBI)
    Last week Alberto published an interesting post about Counting Products in the Current Status with PowerPivot . Starting from a question raised from a reader, Alberto described how to solve a common issue (let me know the “current status” of each item at a given point in time starting from a transactions table) by using a single DAX formula. I suggest you to read his post to understand the technical details of that. What is inspiring of this example is that we can look at Vertipaq and DAX from several...(read more)

  • Setting up Ubuntu on my mother's computer

    - by idealmachine
    Intended use My mother had an old Compaq desktop computer running Windows 98, which she used for occasional Web browsing and playing cards. The name of her card game is Hoyle Card Games 3. Although I had to repair it several times over the last 10 years, it worked fine until it finally died at the end of last year. Hardware specifications A relative brought up a newer computer soon afterward: Operating system: Windows XP Asus K8N motherboard (with broken on-board sound; getting a sound card) Athlon 64? processor (don't remember the clock speed) 512 MB RAM Hope the graphics card works... Replacement sound card will be one of: Ensoniq ES1370 AudioPCI Diamond Monster Sound MX300 (Aureal chipset) Sound Blaster Audigy 2 SE Peripherals HP Scanjet 3400c scanner (USB connected) HP LaserJet multi-function printer (parallel port connected, and printing works with a PCL driver) Same serial mouse as old computer Question I had set up an SSH/VNC connection to allow for remotely working out problems. Or so I thought. A month later, the computer would not boot, rendering the SSH connection useless and an OS reinstall necessary. Unfortunately, I have neither the original Windows disc nor the product key. Unless I were to pay $200 for a full Windows 7 Home Premium license for my computer, I would not be able to re-install Windows XP on hers. I consider myself an advanced Linux user, having used Debian for years. So here are my questions. I have only one day to decide whether to use Ubuntu or buy Windows: A quick search leads me to believe all the hardware listed above is supposed to work with Linux, but am I mistaken? Would Ubuntu/Xubuntu suffice (specify which one if it matters), or would I be better off paying the $200 necessary for Windows XP? Is the card game likely to run on Wine? I believe the minimum system requirement is Windows 95. Failing Wine compatibility, will VirtualBox run fast enough on such a computer (Windows 98 as the guest OS)? Are there any free card games just as good? She plays mainly Bridge, Poker, and Solitaire. Is there any "Large Fonts" option for those with poor vision? The lack of it would be a big disadvantage. BONUS: Although I would probably replace the old mouse upon a move to Ubuntu, is it even possible to get a serial mouse working?

  • Do any OO languages support a mechanism to guarantee an overriden method will call the base?

    - by Aaron Anodide
    I think this might be a useful language feature and was wondering if any languages already support it. The idea is if you have: class C virtual F statement1 statement2 and class D inherits C override F statement1 statement2 C.F() There would be a keyword applied to C.F() such that removing the last line of code above would cause a compiler error because it's saying "This method can be overridden but the implementation here needs to run no matter what".

  • PowerPivot: Putting two stocks on the same PivotChart

    - by AlbertoFerrari
    In a previous post , I have used a stock exchange scenario to speak about how to compute moving averages in a complex scenario. Playing with the same scenario, I felt the need to compare two stocks on the same chart, choosing the stock names with a slicer. As always, a picture is worth a thousand words, the final result I want to achieve is something like this, where I am comparing Microsoft over Apple during the last 10 years. It is clear that I am not going to comment in any way why traders seem...(read more)

  • No WiFi after upgrading 12.04 kernel to 3.2.0-24-generic-pae

    - by lunar
    I'm on Ubuntu 12.04 LTS. With the previous kernel everything was okay — until today's upgrade to 3.2.0-24-generic-pae. The device network tools show that my WiFi card is in an inactive state. How can I enable it? These commands don't work: sudo ifconfig wlan0 up sudo /etc/init.d/networking restart The last one returns some weird errors, brackets, tildes, ampersands like in some kind of a loop.

  • C++ and SDL resource management for 2D game

    - by KuruptedMagi
    My first question is about stateManagers. I do not use the singleton pattern (read many random posts with various reasons not to use it), I have gameStateManager which runs the pointer cCurrentGameState-render(), etc. I want to make a transitioning game, this engine should ideally cover both a platformer and a bird's eye RPG (with some recoding, I just mean the base engine), both of which will load different levels and events, such as world map, dungeon, shops, etc. So I then thought, rather then having to store all this data within all the states, I would break the engine into gameStates, and playStates... when gameState reaches gameStatePlay(), gameStatePlay simply runs the usual handleInput, logic, and render for the playStates, just as the low level gameStateManager does. This lets me store all the player data within the base playstate class without storing useless data in the gameStates. Now I have added a seperate mapEditor, which uses editorStates from gameStateEditor. Is this too much usage of the gameState concept? It seems to work pretty well for me, so I was wondering if I am too far off a common implementation of this. My second question is on image resources. I have my sprite class with nothing but static members, mainly loadImage, applySurface, and my screen pointer. I also have a map pairing imageName enums with actual SDL_Surface pointers, and one pairing clipNumber enums with a wrapper class for a vector of clips, so that each reference in the map can have different amounts of clips with different sizes. I thought it would be better to store all these images, and screen within one static body, since 20 different goblins all use the same sprite sheet, and all need to print to the same screen, and of course, this way I do not need to pass my screen reference to every little entity. The imageMap seems to work very well, I can even add the ability to search through the map at creation of entity type to see if a particular image at creation, creating if it doesnt exist, and destroying the image if the last entity that needs it was just destroyed. The vectored clip map however, seems to take too long to initialize, so if i run past the state that initializes them to fast, the game crashes <. Plus, the clip map call is half of this line =P SPRITE::applySurface( cEditorMap.cTiles[x][y].iX, cEditorMap.cTiles[x][y].iY, SPRITE::mImages[ IMAGE_TILEMAP ], SPRITE::screen, SPRITE::mImageClips[IMAGE_TILEMAP]->clips.at( cEditorMap.cTiles[x][y].iTileType ) ); Again, do I have the right idea? I like the imageMap, but am I better off with each entity storing its own clips? My last question is about collision detection. I only grasp the basics, will look at per-pixel and circular soon, but how can I determine which side the collision comes from with just the basic square collision detection, I tried breaking each entity into 4 collision zones, but that just gave me problems with walking through walls and the like <. Also, is per-pixel color collision a good way to decide what collision just occured, or is checking multiple colors for multiple entities too taxing each cycle?

  • Ubuntu 12.04 - Wakes from Suspend by itself

    - by Peter
    This problem has only just started and I don't know what has changed to cause it. I suspend my ubuntu 12.04 PC and it used to stay asleep until I hit the enter key to wake it up but for the last week or so it's been waking itself up. I've checked the BIOS settings and all the Wake on Lan settings are Disabled. I've used the ethtool command and the wake on lan is set to "d" which I've read been off. Can anyone suggest anything?

  • SSIS Expression to Find Text Between Characters

    - by Compudicted
    It will be a super short and looks like the first and last post in January 2011. So back to the topic, I decided to share an SSIS expression I crafted to extract the value concealed between two characters (I needed to get a portion of text in a file path): Substring(@[User::MyString],FINDSTRING(@[User::MyString],"(",1)+1,FINDSTRING(@[User::MyString],")",1) - FINDSTRING(@[User::MyString],"(",1)-1) The value of MyString say could be c:\test\test(testing123456789).txt, then the resulting text captured testing123456789. Hopefully it will be needed to somebody.

  • Small hiccup with VMware Player after upgrading to Ubuntu 12.04

    The upgrade process Finally, it was time to upgrade to a new LTS version of Ubuntu - 12.04 aka Precise Pangolin. I scheduled the weekend for this task and despite the nickname of Mauritius (Cyber Island) it took roughly 6 hours to download nearly 2.400 packages. No problem in general, as I have spare machines to work on, and it was weekend anyway. All went very smooth and only a few packages required manual attention due to local modifications in the configuration. With the new kernel 3.2.0-24 it was necessary to reboot the system and compared to the last upgrade, I got my graphical login as expected. Compilation of VMware Player 4.x fails A quick test on the installed applications, Firefox, Thunderbird, Chromium, Skype, CrossOver, etc. reveils that everything is fine in general. Firing up VMware Player displays the known kernel mod dialog that requires to compile the modules for the newly booted kernel. Usually, this isn't a big issue but this time I was confronted with the situation that vmnet didn't compile as expected ("Failed to compile module vmnet"). Luckily, this issue is already well-known, even though with "Failed to compile module vmmon" as general reason but nevertheless it was very easy and quick to find the solution to this problem. In VMware Communities there are several forum threads related to this topic and VMware provides the necessary patch file for Workstation 8.0.2 and Player 4.0.2. In case that you are still on Workstation 7.x or Player 3.x there is another patch file available. After download extract the file like so: tar -xzvf vmware802fixlinux320.tar.gz and run the patch script as super-user: sudo ./patch-modules_3.2.0.sh This will alter the existing installation and source files of VMware Player on your machine. As last step, which isn't described in many other resources, you have to restart the vmware service, or for the heart-fainted, just reboot your system: sudo service vmware restart This will load the newly created kernel modules into your userspace, and after that VMware Player will start as usual. Summary Upgrading any derivate of Ubuntu, in my case Xubuntu, is quick and easy done but it might hold some surprises from time to time. Nonetheless, it is absolutely worthy to go for it. Currently, this patch for VMware is the only obstacle I had to face so far and my system feels and looks better than before. Happy upgrade! Resources I used the following links based on Google search results: http://communities.vmware.com/message/1902218#1902218http://weltall.heliohost.org/wordpress/2012/01/26/vmware-workstation-8-0-2-player-4-0-2-fix-for-linux-kernel-3-2-and-3-3/ Update on VMware Player 4.0.3 Please continue to read on my follow-up article in case that you upgraded either VMware Workstation 8.0.3 or VMware Player 4.0.3.
