• How do I fix a garbled screen on a Gateway LT3103u?

  - by paracaudex

  I've been having garbled screen problems on a Gateway LT3103u on Ubuntu for a while. I just did a fresh install of Ubuntu 11.10 and continue to have issues. I installed xubuntu-desktop in case the issues had to do with the sophisticated GNOME graphics. The problem is less bad, but it's still there. After a few minutes of using XFCE, the screen gets garbled. I assume this has something to do with the graphics card, but I don't know how to go about troubleshooting something like this. Where should I start? Update: Here is the description of the VGA card from lspci -vvv: 01:05.0 VGA compatible controller: ATI Technologies Inc RS690M [Radeon X1200 Series] (prog-if 00 [VGA controller]) Subsystem: Acer Incorporated [ALI] Device 028c Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast TAbort- SERR- [disabled] Capabilities: [50] Power Management version 2 Flags: PMEClk- DSI- D1+ D2+ AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot-,D3cold-) Status: D0 NoSoftRst- PME-Enable- DSel=0 DScale=0 PME- Capabilities: [80] MSI: Enable- Count=1/1 Maskable- 64bit+ Address: 0000000000000000 Data: 0000 Kernel driver in use: radeon Kernel modules: radeon Update: Setting GRUB_CMDLINE_LINUX="nomodeset" in /etc/default/grub seems to have fixed it in both Ubuntu and xubuntu-desktop. I will test it for a day or so to see if the problems recur and then post more detail with some links to an explanation. Update 2: It is possible to use this fix for Nvidia card (GTX 260) when graphics is defective after 11.10 upgrade/install? First few restarts was graphic ok, then after few restarts begins suddenly be defective and it stay so. I must returned to 11.04 because this problem and I wait for 12.04. So I hope in this fix.

• C# and Unity - Learning to Develop a game by developing the game I want to develop

  - by 97s

  So I am pretty new to C#, I have some python and javascript experience, but nothing substantial. I have read a lot about C# and Unity and I know they are the tools I want to use. My question is: Should I be reading books about C# or should I just start hacking in unity and piecing the game together part by part? Right now I am going through the book, HeadFirst C#, and it is very good, but I taught myself web design and javascript by just creating and hacking until I got the results I wanted then looked at other code to see ways they did it and improved my code. The issue is that with the browser I got immediate results and it was all under one roof, where developing games is a completely different monster. I am just wondering if my time would be better spent buying a book that uses C# to teach you unity, and doing that instead, or if the time spent in HeadFirst book is going to be valuable. Thanks a ton, I am having difficulties using my time, and I just want to maximize it as I don't have a lot of free time. Edit: Hopefully this isn't to broad? If it is, I will delete and go elsewhere just let me know. Thanks.

• Antenna Aligner Part 8: It's Alive!!!

  - by Chris George

  Finally the day has come, Antenna Aligner v1.0.1 has been uploaded to the AppStore and . "Waiting for review" .. . fast forward 7 days and much checking of emails later WOO HOO! Now what? So I set my facebook page to go live  https://www.facebook.com/AntennaAligner, and started by sending messages to my mates that have iphones! Amazingly a few of them bought it! Similarly some of my colleagues were also kind enough to support me and downloaded it too! Unfortunately the only way I knew they had bought is was from them telling me, as the iTunes connect data is only updated daily at about midday GMT. This is a shame, surely they could provide more granular updates throughout the day? Although I suppose once an app has been out in the wild for a while, daily updates are enough. It would, however, be nice to get a ping when you make your first sale! I would have expected more feedback on my facebook page as well, maybe I'm just expecting too much, or perhaps I've configured the page wrong. The new facebook timeline layout is just confusing, and I'm not sure it's all public, I'll check that! So please take a look and see what you think! I would love to get some more feedback/reviews/suggestions... Oh and watch out for the Android version coming soon!

• no aparece grub con gpt windows/ubuntu

  - by user100604

  I have an asus k55VM. The problem is that once done the partitions to install windows 7 finalize you and then ubuntu 12.10 the grub not to appear. On having created the table of partitions with gparted I did it in format msdos but then on having installed windows gently accepted me and he says to me that I must do it with format gpt therefore I erase the disc in the assistant of installation and believe a partition of 160 gb Later between with live CD to ubuntu and believe other partitions between which, one ext4 for ubuntu... I install and restart. On having restarted the grub does not go out but if the partitions appear of windows. To seeing if someone helps me am desperate. Thank you very much Tengo un asus k55VM. El problema es que una vez hechas las particiones instalar windows 7 ultimate y luego ubuntu 12.10 no aparece el grub. Al crear la tabla de particiones con gparted lo hice en formato msdos pero luego al instalar windows no me acepta y me dice que debo hacerlo con formato gpt por lo tanto borro el disco en el asistente de instalacion y creo una particion de 160 gb Posteriormente entre con live cd a ubuntu y creo otras particiones entre las cuales, un ext4 para ubuntu... Instalo y reinicio. Al reiniciar no sale el grub pero si aparecen las particiones de windows. A ver si alguien me ayuda estoy desesperado. Muchas gracias

• App installed in ~/usr launches from terminal but not Applications menu (or why does setting ld_library_path in .profile not work as it should)

  - by levesque

  I have built and installed an application under a directory of my choosing, let's say under /home/jim/usr, so files have been put in three-four folders, all under this $HOME/usr folder (e.g., bin, include, lib, share, etc.). I can launch this application from the command line just fine as I added the proper paths to my environement variables PATH and LD_LIBRARY_PATH in ~/.bashrc. I added the same paths to the ~/.profile file, which, if I'm not mistaken, is supposed to be parsed by Ubuntu. Doesn't work. Nothing. Where can I go from there? EDIT: I logged out/in and restarted my computer. Both didn't change a thing. The problem seems to come from the fact that no matter what I do the LD_LIBRARY_PATH environment variable is not properly passed to Ubuntu. Using log files, I found that the application I'm trying to run in this example doesn't find one it's dependencies located in ~/usr/lib. One solution would be to add the /home/jim/usr/lib folder inside a file located in /etc/ld.so.conf.d/, but I don't have admin rights on this machine. Making a wrapper script like this one works: #!/bin/bash export LD_LIBRARY_PATH=$HLOC/usr/lib application &> $HOME/application_messages.log but that would force me to wrap all my home compiled applications with this script. Any ideas? Why does Ubuntu/Gnome remove the LD_LIBRARY_PATH environment variable from my set variables? Is it because trying to do this is bad practice? UPDATE (and solution): As found by Christopher, there is a bug report about this on launchpad. LD_LIBRARY_PATH is unset after parsing of the ~/.profile file. See the bug report. Seems the only solution for now is to make a wrapper script.

• Scanline filling of polygons that share edges and vertices

  - by Belgin

  In this picture (a perspective projection of an icosahedron), the scanline (red) intersects that vertex at the top. In an icosahedron each edge belongs to two triangles. From edge a, only one triangle is visible, the other one is in the back. Same for edge d. Also, in order to determine what color the current pixel should be, each polygon has a flag which can either be 'in' or 'out', depending upon where on the scanline we currently are. Flags are flipped according to the intersection of the scanline with the edges. Now, as we go from a to d (because all edges are intersected with the scanline at that vertex), this happens: the triangle behind triangle 1 and triangle 1 itself are set 'in', then 2 is set in and 1 is 'out', then 3 is set 'in', 2 is 'out' and finally 3 is 'out' and the one behind it is set 'in', which is not the desired behavior because we only need the triangles which are facing us to be set 'in', the rest should be 'out'. How do process the edges in the Active Edge List (a list of edges that are currently intersected by the scanline) so the right polys are set 'in'? Also, I should mention that the edges are unique, which means there exists an array of edges in the data structure of the icosahedron which are pointed to by edge pointers in each of the triangles.

• FULL LIST Difference Edubuntu over Ubuntu

  - by Richard Kemp

  I have always used Edubuntu rather than Ubuntu because I have many children including home educated ones who casually use the education offerings. I appreciate many but not all of the extra offerings. I never got beyond 8.04.4 LTS, so am considering updating. I note now with Edubuntu 12.04 it is 2GB i.e.4 times bigger, even apparently using squashfs. I do now have to consider whether the extra resources are worth it in each computer in my household. I am sick of reading over and over again 'Edubuntu is Unbuntu with extras such as blah blah', and in a different place the same thing but with a different blah blah. I downloaded Edubuntu 12.04 and ran it 'live'. Can't say I got on at all with the Unity Interface (this can be changed when installed), but the apparent education stuff seemed quite small and pathetic, I am obviously not finding it. Is there anywhere a FULL LIST of what Edubuntu has pre-installed has over Ubuntu, so a sensible decision can be made whether to go for it, or just add packages that look relevant to me to Ubuntu. Is there truly no other difference between Unbuntu/Edubuntu but the extra educational packages? (I for example have no school server, but if I understood exactly what is involved, with the number of computers in the house, it may be worth creating one!) Please advise. Thank You.

• So we've got a code review tool, now what can we use for software documents?

  - by Tini

  We're using Subversion as a full CM for code and also for related project documents. We have JIRA and Fisheye. When we wanted to add a peer review tool, we looked at and tested several candidates. Our weighted requirements included both code and document review, but ultimately, the integration with JIRA slanted the scores in Crucible's favor. Atlassian has slammed the door on ever supporting Word or PDF in Crucible. I've tested several workaround methods to make Crucible work for documents without success. (The Confluence/Crucible plug-in was deprecated by Atlassian, so that option is out, too.) I haven't found a plugin for Crucible that adds this functionality, so short of writing my own plug-in, Crucible for documents is unworkable. Word Track Changes doesn't provide a method for true collaboration and commenting. Adobe PDF Comment and Markup is interesting, but doesn't provide a great way to keep a permanent quality record of the conversation. We can't go cloud-based, our documents must be locally hosted on our own server only. We're only on Sharepoint 2007. Help! Anyone have a suggestion?

• Is it possible to transfer a domain without a "gap" in Whois privacy protection?

  - by Guest

  I currently own several domains on which I am using a Whois privacy protection service to hide my personal details. In the near future, I would like to transfer some of these domains to a different registrar. It has been many years since I last performed domain transfers, so I am no longer knowledgeable about what it involves. However, I have read from several registrars that they ask their customers to disable Whois protection before effecting a domain transfer. Since there are several websites out there that publish archived versions of Whois information (and ask handsome money for the information to be hidden, of course), I would prefer to avoid having such a "gap" in my privacy protection. I figured that these websites would fetch Whois information mainly when a query is effected through their own website. However, I have found out that at least one of these sites had a copy of the Whois information for a new domain up on their site within hours after I registered it, so they must have some other source (of course I used a Google search to find that out, not their own site). What that tells me is that the time it takes for the domain transfers to go through would be more than enough for these rogue websites to cache my information. If my new registrar offers privacy protection for domains right from the point of registration as well, is there no way to transfer the domain between the two without reverting to my default Whois information in between?

• Creating sitemap for Googlebot - how to mark dynamic content / dynamic subpages?

  - by ojek

  I have a website that is an Internet forum. This forum has many categories, and a single category page that contains a lot of subpages with listed threads. This Internet forum is brand new, and about a week ago I filled it with a few hundred thousand threads. I then looked at my Google Webmasters Tools page to see any changes in indexing, but the index went up from 300 to about 1200, so that means it did not index my added threads (although it added something). The following is what my sitemap.xml contains, which I uploaded to their website. Of course there is a lot more code, this is just a snippet for a single category. In my real sitemap file I have all the categories listed as below: <url> <loc>http://mysite.com/Forums/Physics</loc> <changefreq>hourly</changefreq> </url> Now, I would expect Googlebot to go into mysite.com/Forums/Physics, and crawl through all the subpages with thread links, and then crawl inside of each thread and index its content. How can I achieve this? Also if this is unclear, I will add a real link to my website.

• Tried teaching myself to program before college, accidently overwhelmed myself, tips?

  - by Gunnar Keith

  I'm sixteen, I'm overly interested in programming, and I'm currently taking IT classes during my mornings in high school. Last year, I tried teaching myself to code. It was quite exciting, but all I did was watch TheNewBoston's videos on YouTube for Python. After his tutorials, I just did research, made some CMD programs, and that's it. After that, I got cocky and got my feet wet in many other languages. Java, C++, C#, Perl, Ruby... and it overwhelmed me. Which made it less fun to code. I want to go to college for a 2 year programming course. And I want to make writing code my profession. But how do you recommend I attack re-learning it all again? Start with Python? Don't even try? Also, I'm not 100% in math, but I'm good friends with a lot of programmers, who say they suck at math, but manage to code just fine. I'm not looking for negative feedback. I just want the proper head-start on things before college.

• What data to send when tracking clicks with Google Analytics events (and how)?

  - by user359650

  When tracking clicks on links, there are 3 items I'm interested in: link location in the page by grabbing the id of the closest parent: to see influence of location on click-through link text: to see influence of text on click-through link href attribute value: to see where people go when leaving my website The problem when using Google Analytics to track those clicks is that events only have 3 available text fields, one of which being the category, which if you use to store one of the above items will create a mess in your Event reporting because you will have as many categories as item values. Therefore if you assign a predefined value to the category (e.g. clicks), then you're left with only 2 event fields (action, label) to store 3 items (location, text, href). That in itself isn't the end of the world because you can concatenate 2 items into 1 event field, then use the reporting or the API to filter things out. Accordingly what I plan on doing is this: category: clicks action: {location_on_page} ¦ {text} label: {href} where {__} are variable values related to the clicked links With this I can easily create some reports directly via the GUI: downloads: include only events where label ends with .pdf click outs to particular domains: include only events where label contains domain And for more complex tasks I need to export the data (or use the API): influence of location on clicks: for each location in the design, count number of events that have that location in the action, then corroborate with pageviews of the corresponding pages. Whilst this looks good I'm wondering if there is a better approach, hence the following questions: Q1: Can you foresee any particular issues with this particular setup (e.g. things I won't be able to report on)? Q2: Can you think of other data that would be interesting to include in the event?

• What is the proper way to maintain the angle of a gun mounted on a car?

  - by Blair

  So I am making a simple game. I want to put a gun on top of a car. I want to be able to control the angle of the gun. Basically it can go forward all the way so that it is parallel to the ground facing the direction the car is moving or it can point behind the car and any of the angles in between these positions. I have something like the following right now but its not really working. Is there an better way to do this that I am not seeing? #This will place the car glPushMatrix() glTranslatef(self.position.x,1.5,self.position.z) glRotated(self.rotation, 0.0, 1.0, 0.0) glScaled(0.5, 0.5, 0.5) glCallList(self.model.gl_list) glPopMatrix() #This will place the gun on top glPushMatrix() glTranslatef(self.position.x,2.5,self.position.z) glRotated(self.tube_angle, self.direction.z, 0.0, self.direction.x) print self.direction.z glRotated(45, self.position.z, 0.0, self.position.x) glScaled(1.0, 0.5, 1.0) glCallList(self.tube.gl_list) glPopMatrix() This almost works. It moves the gun up and down. But when the car moves around, the angle of the gun changes. Not what I want.

• WouldISurviveANuke Assesses Your Distance From Nuclear War Strike Sites

  - by Jason Fitzpatrick

  WouldISurviveANuke is a morbid Google Maps mashup that plots out the effective radius of nuclear weapons on major metropolitan areas, your distance from them, and your chances of survival. Visit the site, plug in your zipcode, and set the parameters (how big of a nuclear weapon and how large the nearest target city needs to be) to find out if you’re in the blast radius. We plugged in a downtown address in Detroit, MI. The verdict? Neither we nor the cockroaches will be coming out alive. If you plug in a location far enough away from the direct blast radius you’ll also get a quality of life report that spells out the effects of a local nuclear strike. As far as startling anti-nuclear proliferation arguments go, WouldISurviveANuke is an effective and interactive demonstration. Hit up the link below to try it out. WouldISurviveANuke [via Y!

• Read-only lock on a SharePoint site collection, or Why can't I edit anymore?

  - by PeterBrunone

  Monday morning, the calls started.  For some reason, long-time users were unable to edit list items.  I figured we had a permissions issue, so I popped in to look at the Site Settings -- and found that I couldn't.  A quick trip to Central Administration showed that I was still listed as a Site Collection Administrator, but I had no power at all on the site collection in question.A quick glance at the logs told me that the server had recently shut down unexpectedly (this is a Hyper-V virtual machine).  Apparently, in the confusion, somehow SharePoint decided to lock the site collection as Read Only.  This can be remedied in one of two ways:1)  In Central Administration, go to Application Management->SharePoint Site Management->Site collection quotas and locks.  Once you have arrived, select the correct application and site collection, and you will have the opportunity to view and set the lock status of the collection (it most likely will be set to "Read-only", and you'll want to move that radio button to "Not locked").2)  Fire up stsadm and issue the following command:stsadm -o setsitelock -url http://myportalsitecollection -lock none

• Unity throws SynchronizationLockException while debugging

  - by pjohnson

  I've found Unity to be a great resource for writing unit-testable code, and tests targeting it. Sadly, not all those unit tests work perfectly the first time (TDD notwithstanding), and sometimes it's not even immediately apparent why they're failing. So I use Visual Studio's debugger. I then see SynchronizationLockExceptions thrown by Unity calls, when I never did while running the code without debugging. I hit F5 to continue past these distractions, the line that had the exception appears to have completed normally, and I continue on to what I was trying to debug in the first place.In settings where Unity isn't used extensively, this is just one amongst a handful of annoyances in a tool (Visual Studio) that overall makes my work life much, much easier and more enjoyable. But in larger projects, it can be maddening. Finally it bugged me enough where it was worth researching it.Amongst the first and most helpful Google results was, of course, at Stack Overflow. The first couple answers were extensive but seemed a bit more involved than I could pull off at this stage in the product's lifecycle. A bit more digging showed that the Microsoft team knows about this bug but hasn't prioritized it into any released build yet. SO users jaster and alex-g proposed workarounds that relieved my pain--just go to Debug|Exceptions..., find the SynchronizationLockException, and uncheck it. As others warned, this will skip over SynchronizationLockExceptions in your code that you want to catch, but that wasn't a concern for me in this case. Thanks, guys; I've used that dialog before, but it's been so long I'd forgotten about it.Now if I could just do the same for Microsoft.CSharp.RuntimeBinder.RuntimeBinderException... Until then, F5 it is.

• How do I create my own programming language and a compiler for it

  - by Dave

  I am thorough with programming and have come across languages including BASIC, FORTRAN, COBOL, LISP, LOGO, Java, C++, C, MATLAB, Mathematica, Python, Ruby, Perl, JavaScript, Assembly and so on. I can't understand how people create programming languages and devise compilers for it. I also couldn't understand how people create OS like Windows, Mac, UNIX, DOS and so on. The other thing that is mysterious to me is how people create libraries like OpenGL, OpenCL, OpenCV, Cocoa, MFC and so on. The last thing I am unable to figure out is how scientists devise an assembly language and an assembler for a microprocessor. I would really like to learn all of these stuff and I am 15 years old. I always wanted to be a computer scientist someone like Babbage, Turing, Shannon, or Dennis Ritchie. I have already read Aho's Compiler Design and Tanenbaum's OS concepts book and they all only discuss concepts and code in a high level. They don't go into the details and nuances and how to devise a compiler or operating system. I want a concrete understanding so that I can create one myself and not just an understanding of what a thread, semaphore, process, or parsing is. I asked my brother about all this. He is a SB student in EECS at MIT and hasn't got a clue of how to actually create all these stuff in the real world. All he knows is just an understanding of Compiler Design and OS concepts like the ones that you guys have mentioned (i.e. like Thread, Synchronization, Concurrency, memory management, Lexical Analysis, Intermediate code generation and so on)

• What can be done to decrease the number of live issues with applications?

  - by User Smith

  First off I have seen this post which is slightly similar to my question. : What can you do to decrease the number of deployment bugs of a live website? Let me layout the situation for you. The team of programmers that I belong to have metrics associated with our code. Over the last several months our errors in our live system have increased by a large amount. We require that our updates to applications be tested by at least one other programmer prior to going live. I personally am completely against this as I think that applications should be tested by end users as end users are much better testers than programmers, I am not against programmers testing, obviously programmers need to test code, but they are most of the times too close to the code. The reason I specify that I think end users should test in our scenario is due to the fact that we don't have business analysts, we just have programmers. I come from a background where BAs took care of all the testing once programmers checked off it was ready to go live. We do have a staging environment in place that is a clone of the live environment that we use to ensure that we don't have issues between development and live environments this does catch some bugs. We don't do end user testing really at all, I should say we don't really have anyone testing our code except programmers, which I think gets us into this mess (Ideally, we would have BAs or QA or professional testers test). We don't have a QA team or anything of that nature. We don't have test cases for our projects that are fully laid out. Ok, I am just a peon programmer at the bottom of the rung, but I am probably more tired of these issues than the managers complaining about them. So, I don't have the ability to tell them you are doing it all wrong.....I have tried gentle pushes in the correct direction. Any advice or suggestions on how to alleviate this issue ?

• Is there any research out there on geographic differences in work environments (e.g., respect) for programmers?

  - by Ethel Evans

  One thing I've learned from this website is that software developers are not treated the same as what I've seen in the companies I've worked at, and some of the differences seem to be related to the culture or other factors of the geographical location where the programmer works. In some areas, it seems like programmers can expect many perks and a great deal of professional respect, but in others it sounds like programmers are seen as laborers who are told what to do and then should go do it without question. Even in just the USA, there seem to be major differences in "the norm" between the various regions of this country. I'm wondering how much of this is just my perception, and how much is real differences about how programmers are perceived in their different locations. Is there any research out there discussing major differences in programmer work environments or attitudes about how to treat or respect programmers by geography? I'd be interested in multiple articles tackling different ways of looking at this. Edit: Research, specifically, doesn't seem to be available, so I'm making the question broader. Any good, thoughtful writing on the topic of any kind available?

• What to Return with Async CRUD methods

  - by RualStorge

  While there is a similar question focused on Java, I've been in debates with utilizing Task objects. What's the best way to handle returns on CRUD methods (and similar)? Common returns we've seen over the years are: Void (no return unless there is an exception) Boolean (True on Success, False on Failure, exception on unhandled failure) Int or GUID (Return the newly created objects Id, 0 or null on failure, exception on unhandled failure) The updated Object (exception on failure) Result Object (Object that houses the manipulated object's ID, Boolean or status field to with success or failure indicated, Exception information if there was one, etc) The concern comes into play as we've started moving over to utilizing C# 5's Async functionality, and this brought the question up of how we should handle CRUD returns large-scale. In our systems we have a little of everything in regards to what we return, we want to make these returns standardized... Now the question is what is the recommended standard? Is there even a recommended standard yet? (I realize we need to decide our standard, but typically we do so by looking at best practices, see if it makes sense for us and go from there, but here we're not finding much to work with)

• Farseer: Cutting body from texture

  - by Robin Betka

  Is it possible to cut a body from a texture in Farseer 3.0? I have a texture converted to a body with multiple fixtures ( using BayazitDecomposer, CreatePolygon method, ..) and can even do it as a BreakableBody. But when I try to cut it with the cutting tool, the fixture itself gets cutted but it's connections get discarded! So when I have 14 fixtures, and cut fixture 3 for example, fixture 3 gets cutted but 1,2 and 3-14 just go away. Is there a way to do it? It would work already if I could convert the texture into a body with 1 fixture only, but I haven't figured out it that's possible. BayazitDecomposer creates the multiple verticles, but letting it away creates something weird and I get assert messages all the time. I know I couldn't break it that way but I don't need that anyway when I could cut it. The breaking is just the work around I'm using now. Extending the cuttingtool to support multiple fixtures is very hard especially when you consider that in one cut multiple fixtures could be cutted and then connected again.

• Did Oracle make public any plans to charge for JDK in the near future? [closed]

  - by Eduard Florinescu

  I recently read an article: Twelve Disaster Scenarios Which Could Damage the Technology Industry which mentioned among other the possible "disaster scenarios" also: Oracle starts charging for the JDK, giving the following as argument: Oracle could start requiring license fees for the JDK from everyone but desktop users who haven't uninstalled the Java plug-in for some reason. This would burn down half the Java server-side market, but allow Oracle to fully monetize its acquisitions and investments. [...] Oracle tends to destroy markets to create products it can fully monetize. Even if you're not a Java developer, this would have a ripple effect throughout the market. [...] I actually haven't figured out why Larry hasn't decided Java should go this route yet. Some version of this scenario is actually in my company's statement of risks. I know guessing for the future is impossible, and speculating about that would be endless so I will try to frame my question in an objective answarable way: Did Oracle or someone from Oracle under anonymity, make public, or hinted, leaked to the public such a possibility or the above is plain journalistic speculation? I am unable to find the answer myself with Google generating a lot of noise by searching JDK.
