• Oracle Exalogic Elastic Cloud - Planned Webcasts

  - by chuck.speaks

  I’m putting together a collection of recorded webcasts around Oracle Exalogic Elastic Cloud (Exalogic).  The plan is to do a systems overview and then multiple deep dives into hardware and software components that make up the engineered system. Those of you that are members of our partner community (Oracle Partner Network), drop me a note if you are interested in a full blown in-class delivery via PTS resources.  There is no schedule for these workshops but if there is enough interest, I would venture to guess it would roll out soon. Those of you with applications certified on Oracle WebLogic server that would like to scale to Exalogic, see me or watch this space.   Chuck Speaks chuck <dot> speaks at oracle <dot> com

• Dynamically pulling images from XML for iPhone App

  - by Simon Hume

  I've got my iPhone app pulling down live data content via XML nicely, and I've formatted the UITableView cells to display the content without too many headaches. However, at the moment, for each cell I'm just showing a default graphic for now, but I want this to be pulled down from my server too. The code snippet that grabs the image (which is actually in my project) is: cell.imageView.image = [UIImage imageNamed:@"TBC.png"]; But that will need to be the dynamic image. In my XML, am I better just returning 'mypic.png' and let the SDK determine the full path, like http://myapp.com/mypic.png or storing the full URL to the image in the XML?

• Editor's Notebook: Of Slobber Pots and Flux Capacitors

  - by user462779

  Just wrapping up the contents of the November 2012 issue of Profit... I found this snippet of an interview I did with Team Oracle mechanics Clyde Greene and Chad Colberg when I was in Gary, IN this summer working on a photo shoot about Team Oracle for the current issue. We were standing around in a hangar as the Team prepared for the Chicago Air and Water Show, chatting about the engineering and design of the Oracle Challenger III aerobatic plane. Pick up a copy of Profit's November 2012 and read what Team Oracle pilot Sean D. Tucker has to say about the Oracle Challenger III and get a closer look at the plane. I'll drop a link into this blog entry as soon as the story is available. Your editor, greasy and stooped after a red eye flight, talks with Sean D. Tucker about stunt flying.

• Windows Command Line

  - by Markus O'Reilly

  Does anyone know how to break out of a for loop when it's typed directly into the windows command-line? I know you can use gotos and labels to break out of it when it's in a batch file, but I can't find anything about breaking out of one on the command line. Here's a simple example: C:> for /l %i in (1,0,1) do @ping -n 1 google.com || (echo ^G & msg user "Google is down!" & QUIT) This should infinitely ping google.com. If it ever fails, it beeps (echo ^G), displays a message box to the user "user" that says "Google is down!", and QUITs. I don't know how to do the quit part though. I guess I could do something like taskkill /f /im cmd.exe, but I was looking for something more elegant. Any tips?

• Android ScrollView jumps around when setting child visibility to View.GONE

  - by Mike

  I have a ScrollView that contains an number of other views (TextViews, ImageViews, etc.). The ScrollView is taller than the screen. I have an AsyncTask that updates the children of the ScrollView based on an http response. I've discovered an interesting behavior that I can't figure out how to work around. If I set any of the children's visibilities to View.INVISIBLE as part of the AsyncTask.onPostExecute(), everything works fine. However, if I set any of the children's visibilities to View.GONE, the ScrollView jumps down from the top when onPostExecute() is called. Exactly how far seems to vary. I'm guessing that re-laying out the ScrollView is causing it to scroll away from the top for some reason. So the question is: is there a way to either prevent or work around this behavior? PS. Using ScrollView.jump(FOCUS_UP) as a workaround isn't ideal since that'll force the user to the top even if they had intended to scroll down.

• SharePoint Lookup Field 20 Item JS error

  - by Chops

  Hi Everyone, I've got an issue with SharePoint Server 2007 SP1 which seems to be documented in various forms, but I haven't been able to find an answer to my seemingly simpler question. http://social.msdn.microsoft.com/Forums/en-US/sharepointcustomization/thread/040533d2-c738-4ac2-b2d6-65a1602fa2d1 Essentially, we have a form with a lookup field to another SharePoint list. The lookup field has more than 20 items, and so SharePoint changes the type/behaviour of the field as per the standard behaviour. However, with my custom skin applied, clicking on this drop down causes a JS error from within the Core.js file, as described here: http://splitnut.blogspot.com/2009/06/lookup-fields-in-moss-javascript-error.html What I haven't been able to figure out is why this is only an issue when my custom master page is applied, and not the OOTB master pages. I've been through and tried to see what might cause this, but haven't been able to track down the cause of the behaviour. Any help would be much appreciated. Many thanks.

• {solved}stream TV audio through mic input?

  - by Drew S

  I have a gaming headset and use it with a few devices and am looking for a way to stream my audio through my pc from tv through the mic jack and then through the optical out. the system is detecting sound from the mic port. I would put this directly through the headset but that port is being used by my ps3. So I would like a way as I said to stream it through my pc to my headset, and it be great to have an integrated volume option in the sound drop down too. [TV - mic - Ubuntu - headset(optical out)] Ubuntu 13.04 EDIT I found part of a solution. Solution by installing pavucontrol and using "pactl load-module module-loopback latency_msec=1" I can stream the audio through my pc.

• Lubuntu 13.04 mysterious occurence of icons appearing to be dragged

  - by Jimmy

  On Lubuntu 13.04 every now and again, it appears as if an icon or file is being dragged across the screen...sometimes very short distances, sometimes longer. It seems to happen a short while after moving around Desktop icons. One or more mock drag and drop operations are visible. It's almost as if the actions are being replayed. What could be causing this? Is this a know issue? (Using nvidia-310-updates driver if any help). Any input would be much appreciated! Thank you Jimmy

• Jquery animation in firefox

• Rhapsody TestConductor Experiences

  - by vaiomike

  I was wondering whether anybody out there is actively using Rhapsody TestConductor? Or has tried it for a while, but then decided to turn it down for a particular reason? If so, what are your experiences, in which field do you apply it, what are the shortcomings, or why did you turn it down? At the moment we're considering TestConductor as our tool of choice for testing as it's already integrated into Rhapsody, and would like to find out how applicable it is to our project (btw, we're using Rhapsody 7.4 in C). P.S: Recommendations on good books about Model Based Testing are also appreciated.

• AJAX Requests & Client-Side JavaScript

  - by Sarah24

  I am new to AJAX and trying to understand a question I've been given: A HTTP request is generated by a form which contains some drop-down list. When the form is submitted, a new web page is displayed with some relevant text information (which is dependent on the list item selected). Now, the same parameters are sent to the server via an AJAX request, and the same text information is returned. Q. What tasks would the client-side JavaScript have to do to ensure a valid request was constructed and sent? Any useful links or quick explanations greatly appreciated.

• Are there any programs to aid in the mass-editing of Visual SourceSafe checkin comments?

  - by Schnapple

  I know that in Visual SourceSafe you can go in and drill down to the history of an individual file and then drill down to an individual check-in and apply a comment to the check-in that way but that's tedious and time consuming - if you have a lot of files that were checked in at the same time and you want the same comment to apply to all of them this will take forever. I use the tool VSSReporter to generate reports of checkins and other stuff from VSS, but it cannot edit anything, only report on them. Are there any tools which will let you go back and retroactively apply comments to check-ins in an efficient and easy manner?

• No cache and Google AdSense performance

  - by Luca

  I'm developing a page where I need to avoid JavaScript caching by browser. I've added this header: <?php header('Cache-Control: no-cache, no-store, must-revalidate'); header('Pragma: no-cache'); header('Expires: 0'); ?> After this, browsers didn't cache more JavaScript sorting out the issue, but in the same time I noticed a drop in Google AdSense RPM. Then I removed the added code and now Google AdSense RPM is reaching again a good value. So, how could I avoid JavaScript caching without meddle with AdSense performance?

• 2D Spaceship movement math

  - by YAS

  Hi, I'm new here. I'm trying to make a top-down spaceship game and I want the movement to somewhat realistic. 360 degrees with inertia, gravity, etc. My problem is I can make the ship move 360 with inertia with no problem, but what I need to do is impose a limit for how fast the engines can go while not limiting other forces pushing/pulling the ship. So, if the engines speed is a maximum of 500 and the ship is going 1000 from a gravity well, the ship is not going to go 1500 when it's engines are on, but if is pointing away from the angle is going then it could slow down. For what it's worth, I'm using Construct (www.scirra.com), and all I need is the math of it. Thanks for any help, I'm going bald from trying to figure this out.

• Logging which is the best way

  - by Tony

  Hi People who talk about loggers here never talke about EventLog, I think this is good for windows system. Is it reliable, or I found it dead in some bad morning? Why not logging everything at SQLServer, I am creating E-Commerce website, if SQL server down the website will be down anyway. but I am worry about temporally connection failure, what do u think? Why everyone like files, it can be in great size, too big to handle, or maybe I will create another file when a file is too big, and I can create a file with a date. Some one tried MS Enterprise library? talk to me about it. Thanks

• Use trackball for scrolling in Android ListView

  - by gartenkralleb

  hi, i have a ListView, whose content should not be selectable. i set the ListView to choiceMode="none" and set a transparent listSelector. for touch mode it acts as desired. a problem is the use of the trackball. if i try to use it for scrolling, the scroll starts after the 10th push to "down". this is caused by the invisible listSelector, which scrolls down the list until the 10th list item is "invisibily" selected. i try to override dispatchTrackballEvent and do the scrolling with scrollBy, but i did not finished this approach yet, to have a look on alternative suggestions. is there a simple solution for my problem?

• What happens if you're unable to solve a problem?

  - by gablin

  I'm a year away from graduating from university, and I'm really looking forward to solving practical problems. Especially non-trivial ones which require a bit of research and a lot of thinking. But at the same time, that is also my greatest fear - being faced with a problem that I'm unable to solve, no matter how hard I try. And with pressure to deliver code on impending deadlines just around the corner, it does look a bit scary when viewing it from the safe playgrounds on uni (where the worst thing that can happen is that you have to redo a course or exam). So for those who have been in industry for any longer length of time, what would happen if you were told to solve a problem that you couldn't? Has it happened, and if so, what did happen? Did they just drop it and said "Oh well, guess we can make do with something else"? Were there consequences? Were you reprimanded, or even fired?

• jQuery selector for document and another element

  - by James

  Can I merge these in jQuery? I'm using the HotKeys plugin. $(document).bind('keydown', 'n', cycleNoise); $(document).bind('keydown', 's', pickRandom); $(document).bind('keydown', 'v', toggleTasks); $(document).bind('keydown', 't', toggleTimer); $(document).bind('keydown', 'up', hideTask); $(document).bind('keydown', 'down', nextTask); $('#duration').bind('keydown', 't', toggleTimer); $('#duration').bind('keydown', 'n', cycleNoise); $('#duration').bind('keydown', 's', pickRandom); $('#duration').bind('keydown', 'v', toggleTasks); $('#duration').bind('keydown', 'up', hideTask); $('#duration').bind('keydown', 'down', nextTask); In other words, is it possible to use document and '#duration' in the same selector. The following doesn't seem to work: $(document + ',#duration').bind(...);

• Will unity stop being a plugin for Compiz?

  - by Murphy1138

  I ask this as with the Unity Desktop running , when I try any games with my Ubuntu 12.04.1 I get so much frame rate drop with Unity and Compiz. If I switch to Gnome-Classic which uses mutter, I get a vast boost in performance. My system is an 8 core AMD with a Nvidia 460 SE that can play anything I chuck at it in Windows and I'm using the latest Nvidia drivers, but even simple games like the humble bundle gets serious lag with Unity and the only cause of this can be compiz (what I can guess). When Steam come to Ubuntu, how will this performance loss be addressed?
