• How to know which partition is which?

  - by user206870

  Well I was just wondering what partition belongs to which. On my computer I have Windows 7 and two Ubuntu systems (it was an accident, which is why I need to know which partition is which).

• Optimize Many-to-Many with SUMMARIZE and Other Techniques

  - by Marco Russo (SQLBI)

  We are still in the early days of DAX and even if I have been using it since 2 years ago, there is still a lot to learn on that. One of the topics that historically interests me (and many of the readers here, probably) is the many-to-many relationships between dimensions in a dimensional data model. When I and Alberto wrote the The Many to Many Revolution 2.0 we discovered the SUMMARIZE based pattern very late in the whitepaper writing. It is very important for performance optimization and it should be always used. In the last month, Gerhard Brueckl also presented an approach based on cross table filtering behavior that simplify the syntax involved, even if it’s harder to explain how it works internally. I published a short article titled Optimize Many-to-Many Calculation in DAX with SUMMARIZE and Cross Table Filtering on SQLBI website just to provide a quick reference to the three patterns available. A further study is still required to compare performance between SUMMARIZE and Cross Table Filtering patterns. Up to now, I haven’t observed big differences between them, even if their execution plans might be not identical and this suggest me that depending on other conditions you might favor one over the other.

• Java language book for an experienced programmer?

  - by Andrew

  I am looking for book to get up to speed with (start with) a Java language. I am experienced (more than 15 years) C# and C++ programmer with a bit of Python, so I don't need a book which starts with a programming concepts for a beginner. In fact I think I need a "Java language specification" sort of book. I checked the answers to questions similar to mine and found that there two books which is being recommended most: "Effective Java" and "Sun Certified Java Programmer". After a quick look at the "Effective Java" I realised it should not be a book to start with, it is a good book (I read all books in Effective C++, STL series and liked them but they are more "good practices" books, rather than a book for a beginners) "Sun Certified Java Programmer" looks closer to what I am after - but goes too slow for me. So I did some more search and found these two books: The Java(TM) Language Specification by Gosling himself Java™ Programming Language, The (4th Edition) by Ken Arnold I gather the first one a little bit dated and the second one is the best Java Language Reference books up to date, but I am not sure - as I am not a Java person to make such judgements. After reading the language reference book I will start learning the basic libraries / packages / namespaces (collections, algorithms, IO, etc) and then something about UI architecture. But that will come later. Question: - which Java Language reference book for an experienced programmer you can recomend ? and why? Cheers.

• crunchbang: it takes up *how* much memory?!?!

  - by Theo Moore

  I've been trying many distros of Linux lately, trying to find something I like for my netbook. I started out with Ubuntu, and I can tell you I am a big fan. Ubuntu is now fast to install, much simpler to administer, and pretty light resource-wise. My original install was the standard 32 bit version of 9.04. I tried the netbook remix version of this release, but it was very, very slow. Even the full-blown version used only about 200mb. Much better than the almost 800 that the recommended Windows y version took. Once the newest release of Ubuntu was released, I decided to try the netbook remx of 10.04. It used even less RAM; only about 150mb. I thought I'd found my OS. I certainly settled in and prepared to use it forever. Then, someone I know suggested I try cunchbang. It is the most minimalistic UI I've ever seen, using Openbox rather than Gnome or KDE. Very slick, simple and clean. Since I am using the alpha of the most recent version (using Debian Squeeze), the apps provided for you are few...although more will be provided soon. You do have a word processor, etc., although not the OpenOffice you would normally get in Ubuntu. But the best part? 48MB. That's it. 48mb fully loaded, supporting what I can "hotel services". It's fast, boots quick, and believe it or not, I can even do Java-based development....on my netbook! Pretty slick.   More on it as I use it.

• Demonstrate bad code to client?

  - by jtiger

  I have a new client that has asked me to do a redesign of their website, an ASP.NET Webforms application that was developed by another consultant. It seemed straight-forward (it never is) but I took a look at the code to make sure I knew what I was in for. This application was not written well. At all. It is extremely vulnerable to SQL Injection attacks, business logic is spread throughout the entire application, a lot of duplication, and dead end code that does nothing. On top of that, it keeps throwing exceptions that are being smothered, so it all appears to be running smoothly. My job is to simply update the html and css, but much of the html is being generated in business logic and would be a nightmare for me to sort everything out. My estimates on the redesign were longer than the client was aiming for, and they are asking why so long. How can I explain to my client just how bad this code is? In their mind, the application is running great and the redesign should be a quick one-off. It's my word against the previous consultant, so how can I actually give simple, concrete examples that a non-technical client would understand?

• SQL SERVER – Using MAXDOP 1 for Single Processor Query – SQL in Sixty Seconds #008 – Video

  - by pinaldave

  Today’s SQL in Sixty Seconds video is inspired from my presentation at TechEd India 2012 on Speed up! – Parallel Processes and Unparalleled Performance. There are always special cases when it is about SQL Server. There are always few queries which gives optimal performance when they are executed on single processor and there are always queries which gives optimal performance when they are executed on multiple processors. I will be presenting the how to identify such queries as well what are the best practices related to the same. In this quick video I am going to demonstrate if the query is giving optimal performance when running on single CPU how one can restrict queries to single CPU by using hint OPTION (MAXDOP 1). More on Errors: Difference Temp Table and Table Variable – Effect of Transaction Effect of TRANSACTION on Local Variable – After ROLLBACK and After COMMIT Debate – Table Variables vs Temporary Tables – Quiz – Puzzle – 13 of 31 I encourage you to submit your ideas for SQL in Sixty Seconds. We will try to accommodate as many as we can.

• Building Single Page Apps on the Microsoft Stack

  - by Stephen.Walther

  Thank you everyone who came to my talk last night on Building Single Page Apps on the Microsoft Stack. I’ve attached the slides and code samples below. Here’s a quick summary of the talk. I argued that Single Page Apps are better than traditional Server Side Apps because: Single Page Apps are Stateful – In a traditional server-side app, whenever you navigate to a new page, all of your previous state is lost. It is like rebooting your computer whenever you perform any action In a Single Page App, Your Presentation Layer is Not Miles Away – In a traditional server-side app, because everything happens on the server, your presentation layer is separated from the user by space and time. In a Single Page App, the presentation layer is in the browser and not the server (which is the right place for a presentation layer). A Single Page App Respects the Web – It is easier to take advantage of HTML5 and related standards when building a Single Page App. Next, I recommended using the following four technologies when building a web application: Knockout – This is how you create your presentation layer. ASP.NET Web API – This is how you expose JSON data from your web server and perform server-side validation. HTML5 – This is how you implement client-side validation. Sammy – This is how you implement client-side routing and create a Single Page App with multiple virtual pages. There are code samples in the download (look in the Samples folder) which demonstrate how all of these technologies work when building Single Page Apps. Powerpoint Sample Code

• Regarding sprite design and resolution for tablets and phones

  - by Dimitris P.

  I am about to start working on a game for android devices, in my spare time, to get familiar with android development. I'm more interested in using the best practices possible than getting a quick result, and that is why I need some guidance regarding graphics. I think the game is going to be fully sprite based. Everything is going to be in .bmp form, or something similar, and my question is: Should I design the sprites in a small resolution (ie for phone screens) and scale them up to fit into larger screens (tablet screens), should I do it vice-versa or should I consider a completely different approach? Would designing a different set of sprites for each of the most used resolution settings be worth it or are there simpler solutions to the problem with fewer drawbacks than the ones I mentioned above? (If I follow the first approach, for example, the larger the screen the worse the graphics will get, since every pixel of the original drawing will cover several pixels on the screen). Is there a standard approach for dealing with this kind of problems? If you need me to be more detailed or more clear about something I mentioned (or forgot to) please don't hesitate to ask. Also, excuse me for any inaccurate use of the English language. Thank you in advance for your input.

• SSIS Technique to Remove/Skip Trailer and/or Bad Data Row in a Flat File

  - by Compudicted

  I noticed that the question on how to skip or bypass a trailer record or a badly formatted/empty row in a SSIS package keeps coming back on the MSDN SSIS Forum. I tried to figure out the reason why and after an extensive search inside the forum and outside it on the entire Web (using several search engines) I indeed found that it seems even thought there is a number of posts and articles on the topic none of them are employing the simplest and the most efficient technique. When I say efficient I mean the shortest time to solution for the fellow developers. OK, enough talk. Let’s face the problem: Typically a flat file (e.g. a comma delimited/CSV) needs to be processed (loaded into a database in most cases really). Oftentimes, such an input file is produced by some sort of an out of control, 3-rd party solution and would come in with some garbage characters and/or even malformed/miss-formatted rows. One such example could be this imaginary file: As you can see several rows have no data and there is an occasional garbage character (1, in this example on row #7). Our task is to produce a clean file that will only capture the meaningful data rows. As an aside, our output/target may be a database table, but for the purpose of this exercise we will simply re-format the source. Let’s outline our course of action to start off: Will use SSIS 2005 to create a DFT; The DFT will use a Flat File Source to our input [bad] flat file; We will use a Conditional Split to process the bad input file; and finally Dump the resulting data to a new [clean] file. Well, only four steps, let’s see if it is too much of work. 1: Start the BIDS and add a DFT to the Control Flow designer (I named it Process Dirty File DFT): 2, and 3: I had added the data viewer to just see what I am getting, alas, surprisingly the data issues were not seen it:   What really is the key in the approach it is to properly set the Conditional Split Transformation. Visually it is: and specifically its SSIS Expression LEN([After CS Column 0]) > 1 The point is to employ the right Boolean expression (yes, the Conditional Split accepts only Boolean conditions). For the sake of this post I re-named the Output Name “No Empty Rows”, but by default it will be named Case 1 (remember to drag your first column into the expression area)! You can close your Conditional Split now. The next part will be crucial – consuming the output of our Conditional Split. Last step - #4: Add a Flat File Destination or any other one you need. Click on the Conditional Split and choose the green arrow to drop onto the target. When you do so make sure you choose the No Empty Rows output and NOT the Conditional Split Default Output. Make the necessary mappings. At this point your package must look like: As the last step will run our package to examine the produced output file. F5: and… it looks great!

• Unity calendar lens not showing events

  - by David_G

  I'm trying to get proper/useful calendar integration into Ubuntu 12.04. I have a Google Calendar (& account) and I want to be able to use this without opening the browser. I want to get the Unity Calendar lens working, so that it shows events coming up, and it allows me a quick way to add new events. However, after installing it, it does not find any events, nor allow me to add a new event. Note that I've installed Lightning 1.4, Evolution mirror 0.2.3, Evolution, and unity-calendar lens. I've also installed Calendar-indicator. I suspect that somehow the lens is not getting the calendar information from thunderbird via evolution. A bit of searching around led me to try this command: /usr/lib/calendar-lens/calendar-lens-daemon.py. With this result: /usr/lib/python2.7/dist-packages/gobject/constants.py:24: Warning: g_boxed_type_register_static: assertion `g_type_from_name (name) == 0' failed import gobject._gobject Traceback (most recent call last): File "/usr/lib/calendar-lens/calendar-lens-daemon.py", line 324, in daemon = Daemon() File "/usr/lib/calendar-lens/calendar-lens-daemon.py", line 80, in init for calendar in evolution.ecal.list_calendars(): AttributeError: 'NoneType' object has no attribute 'list_calendars' Any ideas?

• Including BLOB images in your PDF Reports

  - by thatjeffsmith

  Earlier this year we walked through how to work with BLOBs in Oracle SQL Developer. So you already know how to INSERT, UPDATE and view the BLOBs stored in your tables. But now I want to show you how to include those images in your PDF reports. You know how to work with SQL Developer reports, right? No? OK, let’s do a quick run down memory lane then: How to Build a Bar Chart Child reports – click on parent record for on-the-fly children records Alright, so if you have a GRID report that contains a BLOB column, you have the option of including the BLOB contents when you create a PDF export: At design time, specify how you want the BLOB content to be treated when you export to PDF Note that you must specify the treatment of the BLOBs in the report design. You won’t be prompted when you launch the Export wizard dialog. When you open your PDF, there will be a link to the image. Click it. Click then confirm. It will launch the default image viewer on your machine. I hope your pictures are more excited than mine.

• About to smash my keyboard!! Ubuntu 13.1 issues with AMD driver & Audio

  - by DNex

  Let me preface with saying that this is my 2nd day on Linux. I really want to make it work but these issues are driving me up the wall! I've done exhaustive google searches but have not been able to figure anything out. I am on Ubuntu 13.10, my graphics card is AMD Radeon HD4200. My sound card is a realtek HDMI. I've tried downloading and installing both drivers but nothing works. Graphics card: When I run the .run file (from http://www2.ati.com/drivers/legacy/amd-driver-installer-catalyst-13.1-legacy-linux-x86.x86_64.zip) I get an error. I check the fglrx-install log and it says this: Check if system has the tools required for installation. fglrx installation requires that the system have kernel headers. /lib/modules/3.11.0-12-generic/build/include/linux/version.h cannot be found on this system. One or more tools required for installation cannot be found on the system. Install the required tools before installing the fglrx driver. Optionally, run the installer with --force option to install without the tools. Forcing install will disable AMD hardware acceleration and may make your system unstable. Not recommended. Audio: Since my first install I've had no audio. I've tried everything outlined in this site: http://itsfoss.com/fix-sound-ubuntu-1304-quick-tip/ to no avail. I've download the linux drivers from Realtek HDMI audio but have had no luck. Any help would be extremely appreciated.

• Building Interactive User Interfaces with Microsoft ASP.NET AJAX: Refreshing An UpdatePanel With Jav

  The ASP.NET AJAX UpdatePanel provides a quick and easy way to implement a snappier, AJAX-based user interface in an ASP.NET WebForm. In a nutshell, UpdatePanels allow page developers to refresh selected parts of the page (instead of refreshing the entire page). Typically, an UpdatePanel contains user interface elements that would normally trigger a full page postback - controls like Buttons or DropDownLists that have their AutoPostBack property set to True. Such controls, when placed inside an UpdatePanel, cause a partial page postback to occur. On a partial page postback only the contents of the UpdatePanel are refreshed, avoiding the "flash" of having the entire page reloaded. (For a more in-depth look at the UpdatePanel control, refer back to the Using the UpdatePanel installment in this article series.) Triggering a partial page postback refreshes the contents within an UpdatePanel, but what if you want to refresh an UpdatePanel's contents via JavaScript? Ideally, the UpdatePanel would have a client-side function named something like Refresh that could be called from script to perform a partial page postback and refresh the UpdatePanel. Unfortunately, no such function exists. Instead, you have to write script that triggers a partial page postback for the UpdatePanel you want to refresh. This article looks at how to accomplish this using just a single line of markup/script and includes a working demo you can download and try out for yourself. Read on to learn more! Read More >

• Cropping a line (laser beam) in XNA

  - by electroflame

  I have a laser sprite that I wish to crop. I want to crop it so when it collides with an item, I can calculate the distance between the starting point, and the ending point, and only draw that. This eliminates the "overdraw" of a laser drawing past an item. Essentially, I'm trying to crop a line, but also keep that line "attached" to the nose of my ship. The line should not be drawn past the nose of my ship, that should be the starting point. There is no rotation to worry about. Currently, I thought that doing this through SpriteBatch would be best. This is my current Spritebatch code: spriteBatch.Draw(Laser.sprite, new Rectangle((int)Laser.position.X, (int)Laser.position.Y, Laser.sprite.Width, LaserHeight), new Rectangle(0, 0, (int)(Laser.sprite.Width), LaserHeight), new Color(255, 255, 255, (byte)MathHelper.Clamp(Laser.Alpha, 0, 255)), Laser.rotation, new Vector2(Laser.sprite.Width/2, LaserHeight/2), SpriteEffects.None, 0); But this doesn't quite work. It does only draw part of the sprite, but when LaserHeight is incremented, it lengthens the line in both ways! I believe this is due to some stupid error on my part with the Origin of the draw. Quick recap: I need to have my laser sprite drawn with the bottom of it at the nose of my ship, and then use LaserHeight to crop the image so only part of it is drawn. I have a feeling my explanation is a bit...lacking. So if you require more information, please say so and I will try to provide more information. Thanks in advance!
