• Oracle Database 12c and Oracle Solaris 11 DTrace

  - by Larry Wake

  As you may have heard, Oracle Database 12c is now available for Oracle Solaris and Oracle Linux. Among other things, that means we now have the opportunity to share some of the cool things the Oracle Database and Oracle Solaris engineering teams have been doing together. And here's a good one: In this screencast, Jon Haslam describes how on Oracle Solaris 11, DTrace is now integrated into Oracle Database V$ views to provide a top-to-bottom picture of a database transaction I/O -- from storage devices, through the Oracle Solaris kernel, up to Oracle Database 12c itself: With this end-to-end view, you can easily identify I/O outliers -- transactions that are taking an unusually long time to complete -- and use this comprehensive data to identify and mitigate storage system problems that were previously extremely hard to debug. This is a great example of the power of DTrace, which is just about to celebrate its 10th anniversary in the wild. The screencast has some nice examples of DTrace's power on its own, as well as diving into the DTrace/Oracle Database 12c synergy. There's more, of course.  Over on the OTN Garage blog, Rick Ramsey has put together a nice compendium of ways the OS makes the database scream, and Ginny Henningsen's written an article on the same topic.  And, we've also got an OTN page that digs further into Oracle Database / Oracle Solaris synergies.

• Reverse WiFi to Broadcast connection coming from a USB device

  - by Daniel Clem

  I am using the app called Clockworkmod Tether. It connects using a script ( command line " gksu ./run.sh " ) on the computer. All my programs connect to the internet perfectly, minitube, midori, transmission torrents. But the network manager does not show any connection, wired or wireless. So this may cause issues? What I want to do is take this connection, and be able to share it some way, any way, by wireless. This Acer Timeline "Aspire 5810TZ" does have an Ethernet, so wired out to a router might be an option. But I would prefer to simply reverse the Wireless card to broadcast out to about 2 or 3 devices. Is this possible? Yes I have taken a look at the other questions already posted here, but the answers are 1 year old or older, and not clear at all. I am moderately comfortable (4.5 out of 10 ) on the command line. But pretty much need line by line directions for what commands are needed and what order, ect. Edit I have already tried the method of "Left click network manager, Create New Wireless Network" It is created fine, and I am able to connect to it with a tablet, but am un-able to get an outside connection with it. Using the "Shared to other computers" option because DHCP doesn't seem to work, and WEP Passphrase Security. I get an IP address on the connected device. But as I said, won't bring up any outside webpages or the like. So perhaps this is the wrong approach?

• Kids and programming: ScratchKara

  - by Mike Pagel

  Ever now and then I kept wondering how to share with my kids the excitement of creating something with your computer. Of course, today this is a bit more difficult, as they have seen 3D animation games and well-edited websites. I guess that's why they weren't all that hyped when I found my first computer model at our local recycling facilities (an 8-bit Laser VZ-200 with rubber keys). When I finally got it up and running with an old analog TV set they finally asked whether we could play soccer on it. Needless to say that my showing them how it remembers some BASIC commands and lists and executes them did not make any impression. So the question is for real: How do you get today's kids excited about programming? And just recently I looked again for environments that allow even young kids (mine are 7 and 9 years old now) to do something and have fun. Obviously any real, text-oriented programming language wouldn't work well. To cut it short: Something really nice was built by University of Oldenburg: ScratchKara. It is the perfect mixture of Kara, a simulation of a little ladybug and Scratch, an authoring environment from MIT. ScratchKara allows kids to initially simply explore how the bug moves and turns by pressing the action buttons, then move towards sequencing commands through drag & drop, and eventually end up building algorithms with procedures and functions. Even through it is built for kids and beginners, the environment comes with debugging and refactoring, which I found more than amazing. My kids love it and I have to admit I keep thinking about how to solve a bit more advanced problems with this language, which does not allow you to store any state information (other than your call stack). Yes, I am hooked, too... Once the language is understood you can then move to one of the original Kara versions, where you can define the bug's behavior through finite statemachines, Turing tables, Java and other textual languages. And from there, anything is possible.

• Bing Maps WPF Hack

  - by Chris Gardner

  I've spent the past couple of days adding the Bing Maps WFP Control to an application I'm developing. I kept running into a strange thing that was driving me crazy. I have the control in the bottom of a StackPanel, under a Grid. No matter how hard I tried, setting the Height of the Bing control to Auto would cause the ActualHeight to always be 60.93. Now, I still don't know why this is happening. Truth be told, I'm not too sure I care. I did, however, find a reasonable hack around the problem. I do know the size of everything else. As such, I tied into the SizeChanged Event of the StackPanel. Using this, I could set the Height to the correct size based on the new size of the panel. private void ResizeMap( object sender, SizeChangedEventArgs e ) { myMap.Height = ((StackPanel)sender).ActualHeight - 75.0; } The hard-coded number is was because I had a fixed height of controls above my map. If you have dynamic elements, you could easily iterate through them and delete out the portions. So, there you have it. It's not much, but it annoyed the Smurf out of me for a brief period of time. Since I never found an answer, I figured I'd share.

• In search of database delivery practitioners and enthusiasts

  - by Claire Brooking

  We know from speaking with many of you at tradeshows and user groups that database delivery is not a factory production line. During planning, evaluation, quality control, and disaster mitigation, the people having their say at each step means that successful database deployment is a carefully managed course of action. With so many factors involved at every stage, we would love to find a way for our software to help out, by simplifying processes, speeding them up or joining together the people and the steps that make it all happen. We’re hoping our new research group for database delivery (SQL Server and Oracle) will help us understand the views and experiences of those of you out there in the trenches managing database changes. As part of our new group, we’ll be running a variety of research sessions, including surveys and phone interviews, over coming months. If you have opinions to share on Continuous Integration or Continuous Delivery for databases, we’d love to hear from you. Your feedback really will count as the product teams at Red Gate build plans. For some of our more in-depth sessions, we’ll also be offering participants an Amazon voucher as a thank-you for your time. If you’re not yet practising automated database deployment processes, but are contemplating or planning it, please do consider joining our research group too. If you’d like to sign up to the group and find out more, please fill in a quick form online, and we’ll be in touch to let you know about new research opportunities you might be interested in. We look forward to hearing your stories!

• Working with a company as a Junior Developer [closed]

  - by user1601973

  We all have started our careers in some way or other. Well, I am a college student based in North America & I am doing my second internship with the same company with which I did my first internship. I came back here because people here were helpful always and supportive. But it just happened today, and I wanted to share this on SO. Well since I started I have been doing documentation and that kind of stuff only as compared to my first internship in which I actually worked along with the developers & learned so many things. Well, I was in a conversation with my Team lead, and he asked me if I completed that particular work or not? Well, That particular work had slipped from my mind. He was indeed I kind of pissed, and said "You don't have to worry about it, I will figure out". Well, I felt so bad and was about to literally cry. I stopped my lunch and then went on to complete that work. I always ask for work in office, and I always try to be an asset for whoever I am working but this was the first time that it happened. What are your thoughts on this and should I apologise or not? I think I should.

• How to read default key value with dconf or gsettings?

  - by Zta

  I would like to know the default value of a dconf/gsettings key. My question is a followup of the question below: Where can I get a list of SCHEMA / PATH / KEY to use with gsettings? What I'm trying to do, so create a script that reads all my personal preferences so I can back them up and restore them. I plan to iterate though all keys, like the script above, see what keys have been changed from their default value, and make a note of these, that can be restored later. I see that the dconf-editor display the keys' default value, but I'd very much like to script this. Also, I don't see how parsing the schemas /usr/share/glib-2.0/schemas/ can be automated. Maybe someone can help? gsettings get-default|list-defaults would be nice =) (Geesh, it was much easier in the old days where you just kept your ~/.somethingrc in subversion ... =\ Based on the answer given below, I've updated the script to print schema, key, key's data type, default value, and actual value: #!/bin/bash for schema in $(gsettings list-schemas | sort); do for key in $(gsettings list-keys $schema | sort); do type="$(gsettings range $schema $key | tr "\n" " ")" default="$(XDG_CONFIG_HOME=/tmp/ gsettings get $schema $key | tr "\n" " ")" value="$(gsettings get $schema $key | tr "\n" " ")" echo "$schema :: $key :: $type :: $default :: $value" done done This workaround basically covers what I need. I'll continue working on the backup scrip from here.

• How do you motivate peers to become better developers?

  - by Brian Rasmussen

  In my experience there seems to be two kinds of developers (if we simplify matters a great deal of course). On the one hand we have the developers, who may do a perfectly acceptable job, but who do not really care about the computer science part of their craft. They usually know few languages / technologies and are happy to let things stay that way. For whatever reason, they don't try to improve their computer science skills unless this is required in their current position. On the other hand, we have the geeks or the pragmatic programmers if you subscribe to that idea. They play around with other languages and technologies and usually have knowledge about several topics outside the technical domain of their current job. I would like to see more developers, who are enthusiastic about software development. If you share this point of view, what do you do to push your peers in that direction? Edit: follow-up question inspired by one of the answers: As non-managers, should we really care about this? And why/why not?

• Dirt Cheap Bi-Directional Antenna Wirelessly Extends Your LAN

  - by Jason Fitzpatrick

  If you’re looking for an effective way to link remote LANs without the hassle of laying cable, this DIY bi-directional antenna is a quick (and cheap) method for bringing internet access to outbuildings and other locations. Tinker Danilo Larizza needed to share internet access between apartments that are relatively close together but not hardwired–ruling out simply sharing the access via existing LAN infrastructure. His solution combines a simple scrap wire antenna array mounted inside a plastic food bin (seen here with the cover removed to show the antenna) and some coaxial cable to link the antenna to two routers. Our favorite part about his build is that he constructed the pair to establish if the antenna setup would even work in his location and intended to buy commercial antennas if it did; his Tupperware models worked so well, however, they’re now the permanent solution.

• What You Said: How You Find New Books

  - by Jason Fitzpatrick

  Earlier this week we asked you to share your tips and tricks for finding fresh books to enjoy. Now we’re back with tips ranging from the old school to the digital. SJ highlights several of the most popular web-based tools for finding new books: Goodreads.com is quick and easy. Yournextread.com is fun and helps a lot. But I gotta be honest, Amazon’s suggestions are probably the most useful to me. TheFu suggests checking out award-winning lists and one rather quirky way to pick a good Sci-Fi book: For scifi, see Hugo winning books. Life is too short to read bad books. Sometimes that leads to an author with an entire series of books to enjoy. I really enjoy some of the scifi from the 40s and 50s. Wells stuff is always timeless too (and free). I’m less happy with Nebula winners–-different type of writers and not my personal taste.

• Multi-Resolution Mobile Development

  - by user2186302

  I'm about to start development on my first game for mobile phone (I already have a flash prototype completed so it's jsut a matter of "porting" it to mobile and fixing up the code) and plan on hopefully being able to get the game working on iphones and most android devices. I am using Haxe along with OpenFL and HaxeFlixel for development. My question is: What resolution should I design the game in initially and/or what is the best way to develop a game for multiple resolutions. I have found multiple different methods, the best, in my opinion, being strategy 3 on this page: http://wiki.starling-framework.org/manual/multi-resolution_development. However I have some questions about this. First, what would the best base resolution to use be, the guide suggests 240*320 which seems alright to me, although if I chose to use pixel graphics as I most probably will given I'm using HaxeFlixel, I'm not sure if they'll look too blocky on larger screens which I'm not even sure is a problem as it might still look alright. (Honestly, not sure about that and if anyone has any examples of games that use this method and look nice). Finally, please feel free to share whatever methods you use and think is best. For example, HaxeFlixel has a scaling feature that scales the game to fit the exact screen size, but I'm afraid that would lead to blurry and improperly scaled graphics since it would scale by non-integers. But, I'm not sure how noticeable a problem that may or may not be. Although from experience I'm pretty sure it won't look nice and currently I do not think I'm going to go for this option. So, I would really appreciate any help on this subject. Thank you in advance.

• any online service and/or application to develop a story line for an adventure game?

  - by Gajet

  I with a bunch of friend were talking about an adventure game. there will be too many possibilities in the game and the player can pick from wide varity of choices at each stage to do somthing. there will be consequences for each decision and they may or may not end the story. the result would be somthing like (picture from flashforward series S01E17)or if any of you watched hereos season 1 there is also similar time lines represented as strings in isaac mandez workshop. sorry for bad quality examples but right now I can't think of any better one. do you know any website or application which we can use to create the timeline? these features the least required ones: the ability to represent events as boxes. the ability to connect distant events to each other. the ability to move events on a scene freely the ability to expand the scene easily there should be some color options for the lines representing connections between events easily shareing the idea with one another it's much more better to have a WYSIWYG editor easily explore in the large scene of events in the end if you know any application which could let me create a board just like the one in my sample picture and share it whith other freinds it could help us a lot.

• EPM Architecture: Reporting and Analysis

  - by Marc Schumacher

  Reporting and Analysis is the basis for all Oracle EPM reporting components. Through the Java based Reporting and Analysis web application deployed on WebLogic, it enables users to browse through reports for all kind of Oracle EPM reporting components. Typical users access the web application by browser through Oracle HTTP Server (OHS). Reporting and Analysis Web application talks to the Reporting and Analysis Agent using CORBA protocol on various ports. All communication to the repository databases (EPM System Registry and Reporting and Analysis database) from web and application layer is done using JDBC. As an additional data store, the Reporting and Analysis Agent uses the file system to lay down individual reports. While the reporting artifacts are stored on the file system, the folder structure and report based security information is stored in the relational database. The file system can be either local or remote (e.g. network share, network file system). If an external user directory is used, Reporting and Analysis services also communicate to this directory. The next post will cover WebAnalysis.

• Any ideas about how to make Programming Techniques Class more interesting.

  - by Eedoh

  Hello. I already found similar question here on SO, but almost all the answers were more philosophical, then practical. I'd like You to share some of Your PRACTICAL ideas about how to make my course more interesting. It doesn't matter how much effort it takes from me. I even thought about trying to motivate them to pick some topic in the beginning of the course and to work on it as some kind of real, small, startup project that they could maybe financially exploit once it's finished. But I'm afraid that most of them will not get the project to the end, and that it could be boring to them working on one thing all year long. Also I thought about involving them in Torcs, but I'm afraid most of them wouldn't be up to the task. Btw, Torcs is Car Racing Simulation, but there's an API for developers so they can develop their own AI for the driver, and then race their cars against the other programmer's AI's. I'm not asking here for problem examples, as I asked a separate question about that. I need ideas about making my lectures more interesting and fun.

• What You Said: How You Sync and Organize Your Bookmarks

  - by Jason Fitzpatrick

  Earlier this week we asked you to share your favorite techniques for synchronizing and organizing your browser bookmarks. Now we’re back to highlight the most popular techniques, tricks, and services. By far and away, Xmarks was the most frequently mentioned service. For the unfamiliar, Xmarks is a bookmark syncing service that is packed with features. Not only does Xmarks sync bookmarks between browsers and/or computers it also supports iOS, Android, and BlackBerry (mobile integration requires an upgrade to the premium account). In addition to syncing the bookmarks it also integrates with your search results so you can see how other Xmarks users have ranked sites within your search results. Steve-O-Rama highlights one of the many benefits of Xmarks: Xmarks seems to do the job for me. I’ve got a handful of machines, each with three or four browsers; over the years, I’ve accumulated thousands of bookmarks, stretching across many areas of interest. Trying to keep them all straight had been quite a struggle until Xmarks came along. I freaked out when the company was acquired by LastPass, but was subsequently relieved when they continued the free service. Xmarks has a very nice web interface to access, export, search, organize, and do many other things with your bookmarks. In this way, even if I’m on the go, I can access every bookmark I’ve made. Even so, I still make occasional local backups, directly from the browsers to a network folder. Delicious bookmarks, another veteran of the bookmark syncing services, had a fair number of supporters among the HTG readership.

• Data Movement and the Decision Matrix

  - by BuckWoody

  Maybe it’s my military background, or maybe I’ve always had this predilection, but I like to use two devices when I need to make a complex decision: A checklist and a decision matrix. I like to use a checklist because it ensures that I remember the big bits of what I need to do, and brings up questions or areas that I didn’t think about when evaluating options for the decision. And the decision matrix – that’s the thing I use to actually lay out those options. It’s simply a spreadsheet-like grid (I use Excel, but paper and pencil works as well) that lays out the requirements or advantages for the decision across the top, and the options I have on the left-hand side. Then in the “cells” I put whether or not that option on the left will meet the requirement in that column. I then simply “weight” each cell to organize the choices by best-fit. The right answer (or answers) will float right to the top. I was asked yesterday about options for moving data in SQL Server to another system. There are just dozens of ways to do this, from bcp to Replication, each with certain advantages and costs. But asking the questions for the top row first helped me show the person that it isn’t a particular technology that is important, it’s laying out those requirements and thinking about which elements are more important than the other. For instance, is it more important to have the data moved all the time, or is it OK if that happens once in a while? Does the data have to move in two directions or just one? All of these will help that answer jump right out. Try it sometime – it’s a great learning exercise, since it will force you to focus on filling out the matrix. The answer is out there, Neo.

• Why is there no facility to overload static properties in PHP?

  - by Jon

  Intro PHP allows you to overload method calls and property accesses by declaring magic methods in classes. This enables code such as: class Foo { public function __get($name) { return 42; } } $foo = new Foo; echo $foo->missingProperty; // prints "42" Apart from overloading instance properties and methods, since PHP 5.3.0 we can also overload static methods calls by overriding the magic method __callStatic. Something missing What is conspicuously missing from the available functionality is the ability to overload static properties, for example: echo Foo::$missingProperty; // fatal error: access to undeclared static property This limitation is clearly documented: Property overloading only works in object context. These magic methods will not be triggered in static context. Therefore these methods should not be declared static. As of PHP 5.3.0, a warning is issued if one of the magic overloading methods is declared static. But why? My questions are: Is there a technical reason that this functionality is not currently supported? Or perhaps a (shudder) political reason? Have there been any aborted attempts to add this functionality in the past? Most importantly, the question is not "how can I have dynamic static properties in userland PHP?". That said, if you know of an especially cute implementation based on __callStatic that you want to share then by all means do so.

• My first time in the gambling industry

  - by sfrj

  I am a Java enterprise developer with almost 3 years of professional experience. Soon i am going to have a face to face interview with a company in the gambling industry. I already did successfully a phone screening and now for the personal interview i suppose they will ask me about some kind of white board problem or system design task. I think i am in the right place to ask about this, and would appreciate a lot if someone would give me some tips or share something related to his own experience. The things i am more interested in regarding my interview are: What are the most common challenges for programmers, in this industry? Any idea or suggestion on a white board problem they may ask me? Could you point me to some links where i can find information on the topic or sample problems in this industry?. I personally find this question very interesting not just for me. Also i think, the given answers can help also others in a similar situation. Just what i want to say whit this last comment is: Please avoid, answers like: www.google.com and so on...

• Observable Adapter

  - by Roman Schindlauer

  .NET 4.0 introduced a pair of interfaces, IObservable<T> and IObserver<T>, supporting subscriptions to and notifications for push-based sequences. In combination with Reactive Extensions (Rx), these interfaces provide a convenient and uniform way of describing event sources and sinks in .NET. The StreamInsight CTP refresh in November 2009 included an Observable adapter supporting “reactive” event inputs and outputs.   While we continue to believe it enables an important programming model, the Observable adapter was not included in the final (RTM) release of Microsoft StreamInsight 1.0. The release takes a dependency on .NET 3.5 but for timing reasons could not take a dependency on .NET 4.0. Shipping a separate copy of the observable interfaces in StreamInsight – as we did in the CTP refresh – was not a viable option in the RTM release.   Within the next months, we will be shipping another preview of the Observable adapter that targets .NET 4.0. We look forward to gathering your feedback on the new adapter design! We plan to include the Observable adapter implementation into the product in a future release of Microsoft StreamInsight.

• OpenGL sprites and point size limitation

  - by Srdan

  I'm developing a simple particle system that should be able to perform on mobile devices (iOS, Andorid). My plan was to use GL_POINT_SPRITE/GL_PROGRAM_POINT_SIZE method because of it's efficiency (GL_POINTS are enough), but after some experimenting, I found myself in a trouble. Sprite size is limited (to usually 64 pixels). I'm calculating size using this formula gl_PointSize = in_point_size * some_factor / distance_to_camera to make particle sizes proportional to distance to camera. But at some point, when camera is close enough, problem with size limitation emerges and whole system starts looking unrealistic. Is there a way to avoid this problem? If no, what's alternative? I was thinking of manually generating billboard quad for each particle. Now, I have some questions about that approach. I guess minimum geometry data would be four vertices per particle and index array to make quads from these vertices (with GL_TRIANGLE_STRIP). Additionally, for each vertex I need a color and texture coordinate. I would put all that in an interleaved vertex array. But as you can see, there is much redundancy. All vertices of same particle share same color value, and four texture coordinates are same for all particles. Because of how glDrawArrays/Elements works, I see no way to optimise this. Do you know of a better approach on how to organise per-particle data? Should I use buffers or vertex arrays, or there is no difference because each time I have to update all particles' data. About particles simulation... Where to do it? On CPU or on a vertex processors? Something tells me that mobile's CPU would do it faster than it's vertex unit (at least today in 2012 :). So, any advice on how to make a simple and efficient particle system without particle size limitation, for mobile device, would be appreciated. (animation of camera passing through particles should be realistic)

• Electronics 101 for kids: littleBits review

  - by Daniel Cazzulino

  I'm always on the lookout for cool toys that can empower my kids (9, 6 and 2yo) to be creative and break the mold of being just consumers of other's ideas. I recently came across littleBits while watching a TED video of their creator. I was immediately hooked. It seemed like the perfect blend of simplicity and self-learning that I was looking to get my kids into electronics. So I went ahead and purchased the kit from SparkFun and a bunch of standalone parts (&quot;bits&quot;) from the site itself. There are also a bunch of videos and pictures on their site to get a better idea of what they are, as well as multitude YouTube videos. This weekend I gave them to my kids, and coincidentally, we also travelled to my hometown and they got to share them too with their cousins. Man, what a blast it was! I decided to approach this &quot;toy&quot; just like one of the iPod/iPad games I buy for them: &quot;How it's used? I've no idea! I just heard it was great, you go figure it out!&quot;. And figure it out they did....Read full article

  Hi Linux Community, I find my self struggling with the ever slow and buggy windoze OS once again. It's Time to change with the Ubuntu 10.10 64bit as a really faster Operating System. My Hard Disk laptop as a RECOVERY and HP_TOOLS partition they are both Primary. I Have the System Recovery DVD for Windows 64bit should anything happen. Here's the layout I used with windows before: * (C:) Windows 7 system partition NTFS - 284,89GB (Primary,Boot,Pagefile,Dump) * HP_TOOLS system partition FAT32 - 99MB (Primary) * (D:) RECOVERY partition NTFS - 12,90GB (Primary) * SYSTEM partition NTFS 199MB (Primary) Here's the layout I want to make based on your answers * (C:) Windows 7 system partition NTFS - 60GB (Primary) (sda1) * (D:) Windows DATA partition (user files) NTFS - 120GB(Primary)(sda2);wanna share with Linux * Linux root Ext4 - 100GB (Primary)(sda3) (Ubuntu 10.10 64bit) * Linux swap swap- RAM size, 3GB (sda4) * Linux root Ext3- 15,9GB (Extended)(sda5) (OpenSuse or Puppy) Here is my New Ubuntu 10.10 64bit layout in use now: * SYSTEM partition NTFS 199MB (Primary) (sda1) **Partition 1 does not end on cylinder boundary.(?)** * (C:) Windows 7 system partition NTFS - 90GB (Primary) (sda2) * (D:) Windows 7 RECOVERY partition NTFS - 12,90GB (Primary) (sda3) * Linux system partition EXTENDED - 195GB (Logical) * Linux root Ext4- 10GB (Extended) (sda5) * Linux home Ext3- 185GB (Extended) (sda6) I didn't know if I could wipe all previous partitions when i installed Ubuntu because of the RECOVERY partition so I just made the space for my extended partition by deleting the HP_TOOLS (Fat32). By doing this I managed to make and successfully install Ubuntu 64 but I couldn't actually make the partition for the swap or a third Linux OS. Question 1: What is the right way to Windows 7/Ubuntu 10.10 Dual-Triple Boot Partitioning for Laptop OEM?? Thank you in advance for your advises and suggestions and Happy New Year to All!!
