• Java JRE 7 Automatic Upgrade and Demantra Requirements - Action Required

  - by user702295

  The following applies to ALL Demantra, EBS and Demantra Oracle Integrations: All EBS desktop administrators must disable JRE Auto-Update for their end-users immediately. See this externally-published article:     URGENT BULLETIN: Disable JRE Auto-Update for All E-Business Suite End-Users     https://blogs.oracle.com/stevenChan/entry/bulletin_disable_jre_auto_update Why is this required? If you have Auto-Update enabled, your JRE 1.6 version will be updated to JRE 7.     This may happen as early as July 3, 2012.     This will definitely happen after Sept. 7, 2012, after the release of 1.6.0_35 (6u35).  Oracle Forms is not compatible with JRE 7 yet.  JRE 7 has not been certified with Oracle E-Business Suite yet. Oracle E-Business Suite functionality based on Forms -- e.g. Financials -- will stop working if you upgrade to JRE 7. Related News Java 1.6.0_33 is certified with Oracle E-Business Suite.  See this externally-published article:     Java JRE 1.6.0_33 Certified with Oracle E-Business Suite     https://blogs.oracle.com/stevenChan/entry/jre_1_6_0_33

• Optimized algorithm for line-sphere intersection in GLSL

  - by fernacolo

  Well, hello then! I need to find intersection between line and sphere in GLSL. Right now my solution is based on Paul Bourke's page and was ported to GLSL this way: // The line passes through p1 and p2: vec3 p1 = (...); vec3 p2 = (...); // Sphere center is p3, radius is r: vec3 p3 = (...); float r = ...; float x1 = p1.x; float y1 = p1.y; float z1 = p1.z; float x2 = p2.x; float y2 = p2.y; float z2 = p2.z; float x3 = p3.x; float y3 = p3.y; float z3 = p3.z; float dx = x2 - x1; float dy = y2 - y1; float dz = z2 - z1; float a = dx*dx + dy*dy + dz*dz; float b = 2.0 * (dx * (x1 - x3) + dy * (y1 - y3) + dz * (z1 - z3)); float c = x3*x3 + y3*y3 + z3*z3 + x1*x1 + y1*y1 + z1*z1 - 2.0 * (x3*x1 + y3*y1 + z3*z1) - r*r; float test = b*b - 4.0*a*c; if (test >= 0.0) { // Hit (according to Treebeard, "a fine hit"). float u = (-b - sqrt(test)) / (2.0 * a); vec3 hitp = p1 + u * (p2 - p1); // Now use hitp. } It works perfectly! But it seems slow... I'm new at GLSL. You can answer this questions in two ways: Tell me there is no solution, showing some proof or strong evidence. Tell me about GLSL features (vector APIs, primitive operations) that makes the above algorithm faster, showing some example. Thanks a lot!

• How to become a "faster" programmer?

  - by Nick Gotch

  My last job evaluation included just one weak point: timeliness. I'm already aware of some things I can do to improve this but what I'm looking for are some more. Does anyone have tips or advice on what they do to increase the speed of their output without sacrificing its quality? How do you estimate timelines and stick to them? What do you do to get more done in shorter time periods? Any feedback is greatly appreciated, thanks,

• What is Rainbow (not the CMS)

  - by Jeremy Thompson

  I was reading this excellent blog article regarding speeding up the badge page and in the last comment the author @waffles (a.k.a Sam Saffron) mentions these tools: dapper and a bunch of custom helpers like rainbow, sql builder etc Dapper and sql builder was easy to look up but rainbow keeps pointing me to a CMS, can someone please point me to the real source? Thanks. Obviously the architecture of these [SE] sites is uber cool and ultra fast so no comments on that thanks.

• Webscale is all about sharding and its coming to SQL Azure

  - by simonsabin

  There are many that joke about developers always talking about webscale and needing to shard to be able to scale. In reality many systems, if not most, don’t need to be able to scale to numerous nodes because todays processing is so powerful. However in the cloud world where you don’t have 1 big box you have many little ones (instances) you need some way of sharding/federating/distributing data and load. I’ve mentioned before of a PDC presentation on whats coming in SQL Azure, well they’ve put some...(read more)

• How can Agile methodologies be adapted to High Volume processing system development?

  - by luckyluke

  I am developing high volume processing systems. Like mathematical models that calculate various parameters based on millions of records, calculated derived fields over milions of records, process huge files having transactions etc... I am well aware of unit testing methodologies and if my code is in C# I have no problem in unit testing it. Problem is I often have code in T-SQL, C# code that is a SQL stored assembly, and SSIS workflow with a good amount of logic (and outcomes etc) or some SAS process. What is the approach YOu use when developing such systems. I usually develop several tests as Stored procedures in a designed schema(TEST) and then automatically run them overnight and check out the results. But this is only for T-SQL. And Continous integration IS hard. But the problem is with testing SSIS packages. How do You test it? What is Your preferred approach for stubbing data into tables (especially if You need a lot data initialization). I have some approach derived over the years but maybe I am just not reading enough articles. So Banking, Telecom, Risk developers out there. How do You test your mission critical apps that process milions of records at end day, month end etc? What frameworks do You use? How do You validate that Your ssis package is Correct (as You develop it)/ How do You achieve continous integration in such an environment (Personally I never got there)? I hope this is not to open-ended question. How do You test Your map-reduce jobs for example (i do not use hadoop but this is quite similar). luke Hope that this is not too open ended

• Triple buffering causes input lag?

  - by user782220

  Consider some time in between two vsyncs. Suppose the first display buffer is being used to display the current image, and suppose the game was really fast and computed and rendered the next image to the second display buffer and the next one after that to the third display buffer. That is the rendering to the second and third display buffer happens so fast that it occurs before the next vsync. Suppose input from the user comes in now. What you would like is for the results of the input to show up on the next vsync or (probably more typical) the vsync after that. However, with the third display buffer already rendered the input can only effect the image after that. Meaning the input will only take effect at best 3 vsyncs later. I wish i had an image to show the exact timings of what I mean.

• My laptop hangs a lot

  - by Salahuddin

  My laptop is 1G ram and 120G hard-disk 1.68HZ processor , I've both Ubuntu and Windows7 on my machine For the last few days, my laptop, running Ubuntu 11.10 has been hanging a lot. A lot of the time, the touchpad won't work for unknown reasons, and I have to connect a USB mouse to be able to move the pointer on the screen. When browsing the web, the browser hangs a lot, and I have to restart the laptop to refresh it. I know that there is a hotkey to force Ubuntu to refresh when it hangs, but it doesn't work here.These problems happens only on ubuntu not on windows 7... How do I make Ubuntu light and fast? Help me, please.

• Ubuntu 12.10 running slow

• Improving Comparison Operators and Window Functions

  It is dangerous to assume that your data is sound. SQL already has intrinsic ways to cope with missing, or unknown data in its comparison predicate operators, or Theta operators. Can SQL be more effective in the way it deals with data quality? Joe Celko describes how the SQL Standard could soon evolve to deal with data in ways that allow aggregation and windowing in cases where the data quality is less than perfect

• Spatial data from shapefiles (for T-SQL Tuesday #006)

  - by Rob Farley

  I’m giving a presentation on May 12th at the Adelaide .Net User Group, around the topic of spatial data, and in particular, the visualization of said data. Given that it’s about one the larger types, this post should also count towards Michael Coles’ T-SQL Tuesday on BLOB data . I wrote recently about my experience with exploded data , but what I didn’t go on to talk about was how using a shapefile like this would translate into a scenario with a much larger number of shapes, such as all the postcode...(read more)

• Is there a perf hit using mule as a container vs. standard JEE container like Weblogic?

  - by Victor Grazi

  Our team is considering using Mule in a large scale medium volume internal facing transactional banking application. At first Mule would just be used as an application server although it is possible some of its esb/orchestration features would be used in the future. I have no experience with mule, being new on the team. But my gut says Mule would not be as performant as Weblogic or Glassfish as a deployment container. Does anyone have any comparison stories to share that might shed light?

• Openbox overhead is similar to that with gnome-panel

  - by drN

  I just installed openbox via sudo apt-get install openbox. It already has obconf, btw. I noticed that when I logged into my openbox session instead of the one I usually use (gnome-panel and NOT Ubuntu 2D or one of the high overhead environments) and checked via htop, I found that a similar amount of RAM was being occupied (~600 MB or so) with openbox or gnome-panel. What gives? Openbox looks lighter but it certainly isn't any different. Obviously the same daemons etc would run in both environments as they share the same folders. Is gnome-panel as good as openbox then?

• slow virtualbox guest

  - by ecoologic

  I run a guest ubuntu 12.04 on a host ubuntu 12.04, with virtual box, and the guest is much, much slower than the host (ALT+TAB costs 4-5secs). I had a look around and I found contradicting opinions on virtualbox vs vmware (free), so I taught to keep the former. Both systems are updated, I installed the additions on the guest and I evenly split memory and video memory (64mb) between guest and host. I am running a toshiba m200 laptop with 4GB ram and shared video memory. The host bios does not include a configuration option for machine virtualization. I have 2 cpus and I can't give them both to the vm. Is there anything I overlooked that could solve my problem? Feel free to ask for more info, and thank you for any help. EDIT Idling with the monitor open the (single) guest cpu never gets below 55% and could raise to 80 - 90% just moving the mouse around, opening ff will cause the monitor to run 100% in the guest, while the host shows that both cpus are evenly working around 60%. My cpu is Intel® Core™2 Duo CPU T5450 @ 1.66GHz × 2. If this is not a configuration problem, does it mean my machine is too weak for virtualization?

• Need to Determine the Engine Status?

  - by user702295

  If you need to establish the status of the engine, begin with this SQL: select status, engine, engine_version,fore_column_name from dm.forecast_history The status of an engine run is stored in the FORECAST_HISTORY table, in the “status” field.  We can also find in that table the FORE_COLUMN_NAME field. This field includes the name of the column in SALES_DATA in which the relevant forecast is stored. Here are the possible statuses: -1, -2 : The engine failed in the initialization phase.  Which means, before the engine manager created the engines.  0 : The engine stopped in the optimization phase.  Which means, after the engines were created.  1: The engine finished the run successfully.  2: Forecast was never calculated for the relevant column that is mentioned in FORE_COLUMN_NAME.

• How to avoid the exception “Substitution controls cannot be used in cached User Controls or cached M

  - by DigiMortal

  Recently I wrote example about using user controls with donut caching. Because cache substitutions are not allowed inside partially cached controls you may get the error Substitution controls cannot be used in cached User Controls or cached Master Pages when breaking this rule. In this posting I will introduce some strategies that help to avoid this error. How Substitution control checks its location? Substitution control uses the following check in its OnPreRender method. protected internal override void OnPreRender(EventArgs e) {     base.OnPreRender(e);     for (Control control = this.Parent; control != null;          control = control.Parent)     {         if (control is BasePartialCachingControl)         {             throw new HttpException(SR.GetString("Substitution_CannotBeInCachedControl"));         }     } } It traverses all the control tree up to top from its parent to find at least one control that is partially cached. If such control is found then exception is thrown. Reusing the functionality If you want to do something by yourself if your control may cause exception mentioned before you can use the same code. I modified the previously shown code to be method that can be easily moved to user controls base class if you have some. If you don’t you can use it in controls where you need this check. protected bool IsInsidePartialCachingControl() {     for (Control control = Parent; control != null;         control = control.Parent)         if (control is BasePartialCachingControl)             return true;       return false; } Now it is up to you how to handle the situation where your control with substitutions is child of some partially cache control. You can add here also some debug level output so you can see exactly what controls in control hierarchy are cached and cause problems.

• Switching mdadm to an external bitmap

  - by Oli

  I've just read this in another post about improving RAID5/6 write speeds: After increasing stripe cache & switching to external bitmap, my speeds are 160 Mb/s writes, 260 Mb/s reads. :-D I've already found out how to increase the stripe cache and this worked pretty well but I'd like to know more about an external bitmap. I have an incredibly fast (540MB/s) RAID0 SSD that would do well if a bitmap does what I think it does but I'm still very unsure. I've only known about them as long as I've known this post. A few questions: What is a bitmap (in terms of mdadm)? What are the advantages of an internal bitmap (over external)? What are the advantages of an external bitmap (over internal)? How do I switch between the two? I should add that while this is a I'm-bored-let's-break-something thread, I do value the data stored on the RAID array. If doing this is going to put data at significant risk, please let me know.

• Whats a good structure to save and retrieve locations of images?

  - by Goot

  I got a java-ee application, where I collect informations about movies. Im my backend I provide data like the name, description, genre and a random uuid. I also got lots of related files, which are stored on a file server. Including some screenshots, the dvd or bluRay cover and video trailers. My current approach is: When saving the files to the fileserver, I retrieve the movies random uuid (which is the primary key btw.). I then rename the files screenshot_[UUID]_1, screenshot_[UUID]_2 ... etc. Now, there are lots of other ways to handle this, like saving all filenames in a database or creating a dir structure on the fileserver for every uuid and, e.g., return all images in the "[uuid]/screenshots" folder via REST. I expect about 30k requests a day, so the service has to be pretty performant. Whats the best way to solve this?

• Does connection pooling work fine to execute 60 DB queries to load a page?

  - by willem

  We use Linq2Sql in an ASP.NET application. Unfortunately the eager-loading in Linq2Sql isn't as powerful as in Entity Framework, so a lot of the data has to be lazy loaded as needed. Taking connection pooling into account, is it OK for a web page to execute 60 queries to load a page? Executing a single big query probably won't be much better, as those 60 queries will all those connection pooled connections and not open a new connection each time (which I realize is slow). Any thoughts?
