• Big AdventureWorks2012

  - by jamiet

  Last week I launched AdventureWorks on Azure, an initiative to make SQL Azure accessible to anyone, in my blog post AdventureWorks2012 now available for all on SQL Azure. Since then I think its fair to say that the reaction has been lukewarm with 31 insertions into the [dbo].[SqlFamily] table and only 8 donations via PayPal to support it; on the other hand those 8 donators have been incredibly generous and we nearly have enough in the bank to cover a full year’s worth of availability. It was always my intention to try and make this offering more appealing and to that end I have used an adapted version of Adam Machanic’s make_big_adventure.sql script to massively increase the amount of data in the database and give the community more scope to really push SQL Azure and see what it is capable of. There are now two new tables in the database: [dbo].[bigProduct] with 25200 rows [dbo].[bigTransactionHistory] with 7827579 rows The credentials to login and use AdventureWorks on Azure are as they were before: Server mhknbn2kdz.database.windows.net Database AdventureWorks2012 User sqlfamily Password sqlf@m1ly Remember, if you want to support AdventureWorks on Azure simply click here to launch a pre-populated PayPal Send Money form - all you have to do is login, fill in an amount, and click Send. We need more donations to keep this up and running so if you think this is useful and worth supporting, please please donate.   I mentioned that I had to adapt Adam’s script, the main reasons being: Cross-database queries are not yet supported in SQL Azure so I had to create a local copy of [dbo].[spt_values] rather than reference that in [master] SELECT…INTO is not supported in SQL Azure The 1GB limit of SQLAzure web edition meant that there would not be enough space to store all the data generated by Adam’s script so I had to decrease the total number of rows. The amended script is available on my SkyDrive at https://skydrive.live.com/redir.aspx?cid=550f681dad532637&resid=550F681DAD532637!16756&parid=550F681DAD532637!16755 @Jamiet

• Effective versus efficient code

  - by Todd Williamson

  TL;DR: Quick and dirty code, or "correct" (insert your definition of this term) code? There is often a tension between "efficient" and "effective" in software development. "Efficient" often means code that is "correct" from the point of view of adhering to standards, using widely-accepted patterns/approaches for structures, regardless of project size, budget, etc. "Effective" is not about being "right", but about getting things done. This often results in code that falls outside the bounds of commonly accepted "correct" standards, usage, etc. Usually the people paying for the development effort have dictated ahead of time what it is that they value more. An organization that lives in a technical space will tend towards the efficient end, others will tend towards the effective. Developers often refuse to compromise their favored approach for the other. In my own experience I have found that people with formal education in software development tend towards the Efficient camp. Those that picked up software development more or less as a tool to get things done tend towards the Effective camp. These camps don't get along very well. When managing a team of developers who are not all in one camp it is challenging. In your own experience, which camp do you land in, and do you find yourself having to justify your approach to others? To management? To other developers?

• Our New Website Header (& Other Tweaks)

  - by justin.kestelyn

  Last week, the Oracle Technology Network Website went fixed-width. There are several reasons for this, most relating to providing a consistent user experience, easier management of Website content, etc. Furthermore, it's fairly standard for developer portals these days - java.sun.com, MSDN, and IBM DeveloperWorks are also all fixed-width sites. (My apologies to everyone who is unhappy about this change, but it really is an overall positive one.) Today, we have rolled out a brand-new header, the first step in what we call the "Mosaic" project - which is an effort to make the user experience across all Oracle Websites more consistent. To summarize the impact: The "pull-down" menus on the OTN site disappear; most of them move into a "flyout" button in the header. You can access the OTN flyout from any page on Oracle.com or the OTN site. Great for our page views. :) You also have direct access to the Downloads index from anywhere on Oracle.com. If you so desire, you can directly access product overviews, Oracle University and Support info, Oracle Store, etc etc from the OTN site now. Due to limited space in the flyout we cannot accommodate *all* the pull-down items, but they are all no more than 1 or 2 clicks away. This approach has been validated in extensive user testing over the last few months; I welcome your feedback now in comments. There are many other changes in train, with the next one being: A major homepage redesign, the first in 4 or 5 years.

• Chrome "refusing to execute script"

  - by TestSubject528491

  In the head of my HTML page, I have: <script src="https://raw.github.com/cloudhead/less.js/master/dist/less-1.3.3.js"></script> When I load the page in my browser (Google Chrome v 27.0.1453.116) and enable the developer tools, it says Refused to execute script from 'https://raw.github.com/cloudhead/less.js/master/dist/less-1.3.3.js' because its MIME type ('text/plain') is not executable, and strict MIME type checking is enabled. Indeed, the script won't run. Why does Chrome think this is a plaintext file? It clearly has a js file extension. Since I'm using HTML5, I omitted the type attribute, so I thought that might be causing the problem. So I added type="text/javascript" to the <script> tag, and got the same result. I even tried type="application/javascript" and still, same error. Then I tried changing it to type="text/plain" just out of curiosity. The browser did not return an error, but of course the JavaScript did not run. Finally I thought the periods in the filename might be throwing the browser off. So in my HTML, I changed all the periods to the URL escape character %2E: <script src="https://raw.github.com/cloudhead/less%2Ejs/master/dist/less-1%2E3%2E3.js"></script> This still did not work. The only thing that truly works (i.e. the browser does not give an error and the JS successfully runs) is if I download the file, upload it to a local directory, and then change the src value to the local file. I'd rather not do this since I'm trying to save space on my own website. How do I get the Chrome to recognize that the linked file is actually a javascript type?

• Why am I not getting an sRGB default framebuffer?

  - by Aaron Rotenberg

  I'm trying to make my OpenGL Haskell program gamma correct by making appropriate use of sRGB framebuffers and textures, but I'm running into issues making the default framebuffer sRGB. Consider the following Haskell program, compiled for 32-bit Windows using GHC and linked against 32-bit freeglut: import Foreign.Marshal.Alloc(alloca) import Foreign.Ptr(Ptr) import Foreign.Storable(Storable, peek) import Graphics.Rendering.OpenGL.Raw import qualified Graphics.UI.GLUT as GLUT import Graphics.UI.GLUT(($=)) main :: IO () main = do (_progName, _args) <- GLUT.getArgsAndInitialize GLUT.initialDisplayMode $= [GLUT.SRGBMode] _window <- GLUT.createWindow "sRGB Test" -- To prove that I actually have freeglut working correctly. -- This will fail at runtime under classic GLUT. GLUT.closeCallback $= Just (return ()) glEnable gl_FRAMEBUFFER_SRGB colorEncoding <- allocaOut $ glGetFramebufferAttachmentParameteriv gl_FRAMEBUFFER gl_FRONT_LEFT gl_FRAMEBUFFER_ATTACHMENT_COLOR_ENCODING print colorEncoding allocaOut :: Storable a => (Ptr a -> IO b) -> IO a allocaOut f = alloca $ \ptr -> do f ptr peek ptr On my desktop (Windows 8 64-bit with a GeForce GTX 760 graphics card) this program outputs 9729, a.k.a. gl_LINEAR, indicating that the default framebuffer is using linear color space, even though I explicitly requested an sRGB window. This is reflected in the rendering results of the actual program I'm trying to write - everything looks washed out because my linear color values aren't being converted to sRGB before being written to the framebuffer. On the other hand, on my laptop (Windows 7 64-bit with an Intel graphics chip), the program prints 0 (huh?) and I get an sRGB default framebuffer by default whether I request one or not! And on both machines, if I manually create a non-default framebuffer bound to an sRGB texture, the program correctly prints 35904, a.k.a. gl_SRGB. Why am I getting different results on different hardware? Am I doing something wrong? How can I get an sRGB framebuffer consistently on all hardware and target OSes?

• (Quaternion based) Trouble moving foward based on model rotation

  - by ChocoMan

  Using quaternions, I'm having trouble moving my model in its facing direction. Currently the model moves can move in all cardinal directions with no problems. The problem comes when I rotate the move as it still travelling in the direction of world space. Meaning, if I'm moving forward, backward or any other direction while rotating the model, the model acts like its a figure skater spinning while traveling in the same direction. How do I update the direction of travel proper with the facing direction of the model? Rotates model on Y-axis: Yaw = pController.ThumbSticks.Right.X * MathHelper.ToRadians(speedAngleMAX); AddRotation = Quaternion.CreateFromYawPitchRoll(yaw, 0, 0); ModelLoad.MRotation *= AddRotation; MOrientation = Matrix.CreateFromQuaternion(ModelLoad.MRotation); Moves model forward: // Move Forward if (pController.IsButtonDown(Buttons.LeftThumbstickUp)) { SpeedX = (float)(Math.Sin(ModelLoad.ModelRotation)) * FWDSpeedMax * pController.ThumbSticks.Left.Y * (float)gameTime.ElapsedGameTime.TotalSeconds; SpeedZ = (float)(Math.Cos(ModelLoad.ModelRotation)) * FWDSpeedMax * pController.ThumbSticks.Left.Y * (float)gameTime.ElapsedGameTime.TotalSeconds; // Update model position ModelLoad._modelPos += Vector3.Forward * SpeedZ; ModelLoad._modelPos += Vector3.Left * SpeedX; }

• Examples of limitations in IT due to different bit length by design

  - by Alaudo

  I am teaching the course "Introduction in Programming" for the first-year students and would like to find interesting examples where the datatype size in bits, chosen by design, led to certain known restrictions or important values. Here are some examples: Due to the fact that the Bell teleprinter used 7-bit-code (later accepted as ASCII) until now have we often to encode attachments in electronic messages to contain only 7 bit data. Classical limitation of 32-bit address space leads to the 4Gb maximal RAM size available for 32-bit systems and 4Gb maximal file size in FAT32. Do you know some other interesting examples how the choice of the data type (and especially its binary length) influenced the modern IT world. Added after some discussion in comments: I am not going to teach how to overcome limitations. I just want them to know that 1 byte can hold the values from -127..0..+127 o 0..255, 2 bytes cover the range 0..65535 etc by proving examples they know from other sources, like the above-mentioned base64 encoding etc. We are just learning the basic datatypes and I am trying to find a good reference for "how large" these types are.

• RTFMobile

  - by ultan o'broin

  It may seem obvious but it’s worth stating again. The idea that mobile users are going to read lots of user assistance on their devices is just wrong. So, Jakob Nielsen’s post Mobile Content Is Twice as Difficult serves as a timely reminder for anyone thinking of putting manuals as a form of user assistance onto mobile phones. There is also an excellent post on UXMag.com, explaining that one of the ways to screw up with your iPhone app is to throw an old-style user manual into the user experience: 10 Surefire Ways to Screw Up Your iPhone App.   (Image copyright and referenced from UX Magazine 2010)   Instead, user assistance  alternatives—if any at all—include one-time tours, graphics, in-context instructions, and so on. Not so sure that importing “humor” and “personality” work so well in the enterprise app space, myself. However, the message is clear: iPhone users don’t read manuals. Great message. Users will figure it out, and if they can’t, well then your app’s UX is a problem and the app will fail. Shame some teams are obsessed with figuring out ways to port existing manuals to mobile platforms without any thought for the UX. Razorfish’s Scatter/Gather blog says it all: One thing that is particularly discouraging, most material currently available on “Creating Content for the iPad” or similar themes turns out to be about getting traditional content onto, or into, the iPad. Now, manuals for non-end users in PDF format on eReaders is a different matter. I have research on that, but it’s for another post.

• Strange behavior on Gnome after update on from 13.04 to 13.10

  - by WayneBrady

  I made an automatic update on my Ubuntu 13.10 (from 13.04) system today. Since this point of time, I am in really big trouble. I use a VNC server with Gnome classic, after the update my Gnome was gone. So i tried everything. Checked the xstartup file of vncserver. Right now I reached a point where I can't find the answer. The logfile says that gnome-session-fallback is missing, even directly after I installed it with apt-get (tried it serveral times, installing, uninstalling and so on).

• Algorithm to use for shop floor layout?

  - by jkohlhepp

  I ran into a classroom problem yesterday (business oriented class, not computer science) and I found it interesting from an algorithmic perspective. The problem goes something like this: Assume there is a shop floor with N different rooms, and you have N different departments that need to go in those rooms. The departments and the rooms are all the same size, so any department could go in any room. There is a known travel distance from each room to each other room. There is also a known amount of trips necessary from one department to another (trips are counted the same regardless which room they originate from, so a trip from A to B is equivalent to a trip from B to A). Given those inputs, determine a layout of departments into rooms which minimizes travel time. What is the best way to approach this problem algorithmically? Is there already a particular algorithm or class of algorithms designed to solve this type of problem? Does this type of problem have a name in computer science? I am not looking for you to design an algorithm to solve this, although feel free to do so if you would like. I'm wondering if this is a problem space that has already been well defined and studied algorithmically and if so get some links to research further. I can see a lot of different data structures and algorithms that might apply to this and I'm curious which approach would be "best". And don't worry, you are not doing my homework for me. This is not a homework problem per se, as this is a business course and we were simply discussing the concepts and not trying to solve the problem algorithmically.

• Better ways to have valuable data indexed, which is ignored currently

  - by Sam

  <a title="">.../a> Hi folks. It seems that my title tag which holds extremely valuable and describes contents on my simple design page is currently compeltely denied by search engines and not indexed at all!! Those descriptions should however be indexed as the describe valuable portions to an otherwise empty page with clean glossary (thats neat and organised to the eye of the viewer. So putting all that descriptive data into visible space would ruin the designish less is more fundamental... So, which alternatives to the title tag do I have, in order to put important contents that are relevant for both user as well as search engines? A <a name="">......</> B <p name="">......</> C <a alt="">.......</> D <p alt="">.......</> From the above list, arose my question: Which of the above is advisable alternative in order to get the valuable actual content indexed? Should it be in a a tag or p tag? Or are there even better tags for this which still keep layout clean? You suggestions are Much appreciated!

• Engineering as a Service

  - by jgelhaus

  Oracle Exadata Database Machine is known for great compute performance, and over the past few years, it has also become known as a great platform for any type of Oracle Database workload, from data warehousing to online transaction processing (OLTP). But now organizations are turning to Oracle Exadata for business efficiencies and private cloud solutions—for consolidation and database as a service (DBaaS). University of Minnesota For an inside look at how DBaaS is working in the real world, it’s worth checking into the University of Minnesota’s database hotel.  With more than 50,000 students, the University of Minnesota in Minneapolis is one of the largest universities in the United States. The university’s centralized IT group not only has to support all those students but also must provide support and services to more than 40 departments and colleges within the university. They have two Exadata Database Machine X2-2 half-rack systems from Oracle, with four database nodes each and roughly 30 terabytes of usable disk space for each of the Oracle Exadata systems. The university is using Oracle Real Application Clusters (Oracle RAC) for high availability and the Data Guard feature of Oracle Database, Enterprise Edition, for disaster recovery capabilities. The deployment has been live in production since May 2011. Overhead Door When it comes to overhead, revolving, sliding, or other specialty residential and commercial doors, Overhead Door is the worldwide leader. But when they needed to open doors with their customers through a better, faster, and more agile IT infrastructure, Overhead Door turned to Oracle and Oracle Exadata. Oracle Exadata Database Machine plays an important part in Overhead Door’s IT and business strategy.

• Why is Rhythmbox becoming the default (again)?

  - by Christoph

  So, it seems with 12.04, they're switching back to Rhythmbox, after switching from Rhythmbox a year ago. I don't get why. They say that it's because of a blocking bug in GTK3# (if I understand that correctly), but that's just one bug, and in the same breath they say RB is not well maintained. It seems Ubuntu guys were dissatisfied with Banshee in some way, but apparently the Banshee guys were never notified of any problems. Also, it can't be to save disc space by dropping mono, because at the same day it was announced that the install disc will be enlarged by 50MB. Also, isn't it a bit shortsighted to push Banshee for default inclusion, and then drop it again a year later? How is that a sustainable use of dev resources, or consistent? Apparently there was quite some heavy effort by banshee devs - David Nielsen used the term "bending over backwards for Ubuntu" iirc. In summary: Can anyone shed more light on this? Related question: Why is Banshee becoming the default?

• Two things I learned this week...

  - by noreply(at)blogger.com (Thomas Kyte)

  I often say "I learn something new about Oracle every day".  It really is true - there is so much to know about it, it is hard to keep up sometimes.Here are the two new things I learned - the first is regarding temporary tablespaces.  In the past - when people have asked "how can I shrink my temporary tablespace" I've said "create a new one that is smaller, alter your database/users to use this new one by default, wait a bit, drop the old one".  Actually I usually said first - "don't, it'll just grow again" but some people really wanted to make it smaller.Now, there is an easier way:http://docs.oracle.com/cd/E11882_01/server.112/e26088/statements_3002.htm#SQLRF53578Using alter tablespace temp shrink space .The second thing is just a little sqlplus quirk that I probably knew at one point but totally forgot.  People run into problems with &'s in sqlplus all of the time as sqlplus tries to substitute in for an &variable.  So, if they try to select '&hello world' from dual - they'll get:ops$tkyte%ORA11GR2> select '&hello world' from dual;Enter value for hello: old   1: select '&hello world' from dualnew   1: select ' world' from dual'WORLD------ worldops$tkyte%ORA11GR2> One solution is to "set define off" to disable the substitution (or set define to some other character).  Another oft quoted solution is to use chr(38) - select chr(38)||'hello world' from dual.  I never liked that one personally.  Today - I was shown another wayhttps://asktom.oracle.com/pls/apex/f?p=100:11:0::::P11_QUESTION_ID:4549764300346084350#4573022300346189787 ops$tkyte%ORA11GR2> select '&' || 'hello world' from dual;'&'||'HELLOW------------&hello worldops$tkyte%ORA11GR2>just concatenate '&' to the string, sqlplus doesn't touch that one!  I like that better than chr(38) (but a little less than set define off....)

• Get a culture specific list of month names

  - by erwin21

  A while ago I found a clever way to retrieve a dynamic culture specific list of months names in C# with LINQ. 1: var months = Enumerable.Range(1, 12) 2: .Select(i => new 3: { 4: Month = i.ToString(), 5: MonthName = new DateTime(1, i, 1).ToString("MMMM") 6: }) 7: .ToList(); .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } It’s fairly simple, for a range of numbers from 1 to 12 a DateTime object is created (year and day doesn’t matter in this case), then the date time object formatted to a full month name with ToString(“MMMM”). In this example an anonymous object is created with a Month and MonthName property. You can use this solution to populate your dropdown list with months or to display a user friendly month name.

• VMware Player- no Maverick GUI after install

  - by Jason

  I'm experimenting with using both VMware Player and Virtualbox to run an Ubuntu VM in Win7. I have the VB install of Maverick working fine, and with only a few quirks such as slow response in Firefox scrolling and the occasional freeze, it works fine. However, making backup copies of a VB machine for storage is a PIA, and so I would like to see how Player works in the same situation. I created a new VM with 2GB RAM & 30GB hard drive space. The install went smoothly, but everytime I start the VM, no GUI shows and I have no mouse control. It brings me to a screen saying Ubuntu Easy Install: VMware Player is installing VMware Tools.. please wait. At this point, I get a login prompt and then goes to a standard CLI interface. At this point, I have no mouse control at all. The CPU and memory gauge that I have as a Win7 screenlet shows no changes and minimal HDD activity. The VMWare site says to install the Tools by a tarball, going to VMInstall VMware Tools, but I can't do that with no mouse control. Any solutions?

• Reduce Bookmarks in Chrome to Toolbar Icons

  - by Asian Angel

  Do you want to make the most efficient use of the space in Chrome’s Bookmarks Toolbar? Now you can reduce the bookmarks to icons with just a few minutes work. Note: You may or may not wish to do some reorganizing with your bookmarks before-hand. Condensing the Bookmarks If your browser is anything like ours then it has not taken long to fill up your Bookmarks Toolbar. Accessing the drop-down section often throughout the day is not too fun. The bookmarks are the easiest part of your collection to condense. Right-click on each bookmark and select “Edit…” to open the Edit Bookmark Window. Delete the text, click OK, and you are finished. You still have a useable bookmark that looks nice and takes up very little room. These are our bookmarks from the first screenshot above…no problems with accessing all of them now.

• Dual boot Win 7 Ubuntu - home and boot partitions have no mount point

  - by cwmff

  After installing Ubuntu 12.04.3 on a Windows 7 laptop, running Ubuntu Disk Utility showed the following partition information; /dev/sda1 NTFS, Bootable, Filesystem, Labled: System Reserved, 105MB, Not Mounted /dev/sda2 NTFS, no flag, Filesystem, no label, 84GB, Not Mounted /dev/sda3 Usage: Container for logical partitions.

How do I go about getting sda6 used as the Home partition and sda5 as Boot

• Multiline Replacement With Visual Studio

  - by Alois Kraus

  I had to remove some file headers in a bigger project which were all of the form #region File Header /*[ Compilation unit ----------------------------------------------------------       Name            : Class1.cs       Language        : C#     Creation Date   :      Description     : -----------------------------------------------------------------------------*/ /*] END */ #endregion I know that would be a cool thing to write a simple C# program use a recursive file search, read all lines skip the first n lines and write the files back to disc. But I wanted to test things first before I ruin my source files with one little typo. There comes the Visual Studio Search and Replace in Files dialog into the game. I can test my regular expression to do a multiline match with the Find button before actually breaking anything. And if something goes wrong I have the Undo button.   There is a nice blog post from Paulo Morgado online who deals with Multiline Regular expressions. The Visual Studio Regular expressions are non standard so you have to adapt your usual Regex know how to the other patterns. The pattern I cam finally up with is \#region File Header:b*(.*\n)@\#endregion The Regular expression can be read as \#region File Header Match “#region File Header” \# Escapes the # character since it is a quantifier. :b* After this none or more spaces or tabs can follow (:b stands for space or tab) (.*\n)@ Match anything across lines in a non greedy way (the @ character makes it non greedy) to prevent matching too much until the #endregion somewhere in our source file. \#endregion Match everything until “#endregion” is found I had always knew that Visual Studio can do it but I never bothered to learn the non standard Regex syntax. This is powerful and it is inside Visual Studio since 2005!

• Junit test bluej [closed]

• RAM caching causes severe performance drops

  - by B T

  I have read plenty of threads on memory caching and the standard response of "large cache is good, it shouldn't effect performance", "the kernel knows best". I have recently upgraded from 12.04 to 12.10 and changed from VirtualBox to VMware Workstation and the performance differences are severe (I suspect it is because of the latter). When I am running my virtual machine the system load monitor graph shows less than 50% memory usage generally. System load indicator is showing me that the rest of my RAM is used in the cache all the time. Plain and simple this is the comparison: BEFORE Cache was very sparingly used, pretty much none of my memory usage was the cache Swappiness was 0 (caused my memory to be used first, then swap only if needed) Performance was quite good and logical RAM was used fully first, caching was minimal. I could run enough software to utilize my full 4GB of RAM without any performance degradation whatsoever Swap space was then used as needed which was obviously slower (I am on a HDD) but was still usable when the current program was loaded into memory AFTER Cache is used to fill the full 4GB as soon as my virtual machine is run Swappiness is 0 (same behaviour as before but cache uses full memory straight away) Performance is terrible and unusable while running Ubuntu software Basic things like changing windows takes 2 minutes + Changing screens happens frame by frame over sometimes up to 5 minutes Cannot run an IDE and VM like I could with ease before So basically, any suggestions on how to take my performance back to how it was before while keeping my current setup? My suspicion is VMWare is the problem, but how do I see what is tied to the use of the cache? Surely there is a way to control this behaviour in software as polished as VMware? Thanks EDIT: Could also be important to note that the behaviour differs depending on whether VMware is open or closed. If VMware is open, then the ram will lock at like 50% and 50% cache and go into the complete lock up mentioned above. Contrastingly, if VMware is closed (after being open), then the RAM will continue to rise as it needs / cache will stay as the complete remaining memory and there is no noticeable performance degradation.
