• Introducing the New Face of Fusion Applications

  - by mvaughan

  By Misha Vaughan and Kathy Miedema, Oracle Applications User Experience At OpenWorld 2012, the Oracle Applications User Experience (UX) team unveiled the new face of Fusion Applications. You may have seen it in sessions presented by Chris Leone, Anthony Lye, Jeremy Ashley or others, or you may have gotten a look on the demogrounds. This screenshot shows the new Oracle Fusion Applications entry experience.Why are we delivering a new face for Fusion Applications? Because, says Ashley, the vice president of the Oracle Applications User Experience team, we want to provide a simple, modern, productive way for users to complete their top quick-entry tasks. The idea is to provide a clear, productive user experience that is backed by the full functionality of Fusion Applications. The first release of the new face of Fusion focuses on three types of users. It provides a fully functional gateway to Fusion Applications for: New and casual users who need quick access to self-service tasks Professional users who need fast access to quick-entry, high-volume tasks Users who are looking for a way to quickly brand their portal for employees The new face of Fusion allows users to move easily from navigation to action, Ashley said, and it has been designed for any device -- Mac, PC, iPad, Android, SmartBoard -- in the browser. The Oracle Fusion Applications Employee Directory. How did we build it? The new face of Fusion essentially is a custom shell, developed by the Apps UX team, and a set of page templates that embodies a simple design aesthetic. It’s repeatable, providing consistency across its pages, and requires little to zero training. More specifically, the new face of Fusion has been built on ADF. The Applications UX team created pages in JDeveloper using local tasks flows bound to existing view objects. Three new components were commissioned from ADF, and existing Fusion components were re-skinned to deliver a simple, modern user experience. It really is that simple – and to prove that point, we’ve been sharing our story around the new face of Fusion on several Oracle channels such as this one. Want to know more? Check the VoX blog for our favorite highlights from OpenWorld, which included demos of the new face of Fusion. And take a look at these posts from Ace Directors Debra Lilley, and Floyd Teter. Special mention to Floyd for the first screen shot credit. Also a nod to Wilfred vander Deijl for capturing the demo to share as part 1 and part 2. We will also be hitting upcoming user group conferences with our demos, and you can always reach out to one of our Fusion User Experience Advocates for a look.

• Ghost team foundation build controllers

  - by Martin Hinshelwood

  Quite often after an upgrade there are things left over. Most of the time they are easy to delete, but sometimes it takes a little effort. Even rarer are those times when something just will not go away no matter how much you try. We have had a ghost team build controller hanging around for a while now, and it had defeated my best efforts to get rid of it. The build controller was from our old TFS server from before our TFS 2010 beta 2 upgrade and was really starting to annoy me. Every time I try to delete it I get the message: Controller cannot be deleted because there are build in progress -Manage Build Controller dialog   Figure: Deleting a ghost controller does not always work. I ended up checking all of our 172 Team Projects for the build that was queued, but did not find anything. Jim Lamb pointed me to the “tbl_BuildQueue” table in the team Project Collection database and sure enough there was the nasty little beggar. Figure: The ghost build was easily spotted Adam Cogan asked me: “Why did you suspect this one?” Well, there are a number of things that led me to suspect it: QueueId is very low: Look at the other items, they are in the thousands not single digits ControllerId: I know there is only one legitimate controller, and I am assuming that 6 relates to “zzUnicorn” DefinitionId: This is a very low number and I looked it up in “tbl_BuildDefinition” and it did not exist QueueTime: As we did not upgrade to TFS 2010 until late 2009 a date of 2008 for a queued build is very suspect Status: A status of 2 means that it is still queued This build must have been queued long ago when we were using TFS 2008, probably a beta, and it never got cleaned up. As controllers are new in TFS 2010 it would have created the “zzUnicorn” controller to handle any build servers that already exist. I had previously deleted the Agent, but leaving the controller just looks untidy. Now that the ghost build has been identified there are two options: Delete the row I would not recommend ever deleting anything from the database to achieve something in TFS. It is really not supported. Set the Status to cancelled (Recommended) This is the best option as TFS will then clean it up itself So I set the Status of this build to 2 (cancelled) and sure enough it disappeared after a couple of minutes and I was then able to then delete the “zzUnicorn” controller. Figure: Almost completely clean Now all I have to do is get rid of that untidy “zzBunyip” agent, but that will require rewriting one of our build scripts which will have to wait for now.   Technorati Tags: ALM,TFBS,TFS 2010

• Keyboard Shortcuts in Oracle SQL Developer

  - by thatjeffsmith

  The CTRL key, which stands for ConTRoL…aw, the good ole days What keyboard shortcuts should EVERY Oracle SQL Developer user know? How do you find new shortcuts to master, and how do you change them to match ones you’ve already learned in other tools? These are the driving questions for today’s post. While some of us may be keyboard ninjas, and others are more driven to use the mouse – everyone has probably picked up a few strategic keyboard shortcuts over the years. For example, I’ve personally JUST memorized the Cmd-Shift-4 ‘trick’ in Mac OS X. And of course we all know what F1 does, right? Right?!? Here are a few more keyboard shortcuts to commit to memory. My Favorite SQL Developer Shortcuts ctrl-enter : executes the current statement(s) F5 : executes the current code as a script (think SQL*Plus) ctrl-space : invokes code insight on demand Code Editor – Completion Insight – Enable Completion Auto-Popup (Keyword being Auto) ctrl-Up/Dn : replaces worksheet with previous/next SQL from SQL History ctrl-shift+Up/Dn : same as above but appends instead of replaces shift+F4 : opens a Describe window for current object at cursor ctrl+F7 : format SQL ctrl+/ : toggles line commenting ctrl+e : incremental search Configuring Keyboard Shortcuts in SQL Developer Tools Preferences Shortcut Keys Search by command name OR the keystroke itself Some tips… Sort by category Pay special attention to the ‘Code Editor’ and ‘Other’ categories Mind the conflicts when you change the defaults Be nice – share! You can save your new mappings with your co-workers using the Export and Import buttons Click on ‘More Actions’ to expose the Import and Export buttons When I get ‘bored’ or if I think I might be missing something, I peruse the Code Editor and Other categories, again! I’ve picked up quite a few cool editor tricks here. Then I blog about them, like they’re ‘magic.’ #EvilLaugh But the main tip is this – don’t let your previously memorized keyboard shortcuts SHORTCUT your usage of SQL Developer. If your fingers have already memorized some keystrokes, just re-program SQL Developer to match! What’s your favorite shortcut? I’ll use the most popular shortcut mentioned in the comments to round out my Top 10 list above!

• on coding style

  - by user12607414

  I vastly prefer coding to discussing coding style, just as I would prefer to write poetry instead of talking about how it should be written. Sometimes the topic cannot be put off, either because some individual coder is messing up a shared code base and needs to be corrected, or (worse) because some officious soul has decided, "what we really need around here are some strongly enforced style rules!" Neither is the case at the moment, and yet I will venture a post on the subject. The following are not rules, but suggested etiquette. The idea is to allow a coherent style of coding to flourish safely and sanely, as a humane, inductive, social process. Maxim M1: Observe, respect, and imitate the largest-scale precedents available. (Preserve styles of whitespace, capitalization, punctuation, abbreviation, name choice, code block size, factorization, type of comments, class organization, file naming, etc., etc., etc.) Maxim M2: Don't add weight to small-scale variations. (Realize that Maxim M1 has been broken many times, but don't take that as license to create further irregularities.) Maxim M3: Listen to and rely on your reviewers to help you perceive your own coding quirks. (When you review, help the coder do this.) Maxim M4: When you touch some code, try to leave it more readable than you found it. (When you review such changes, thank the coder for the cleanup. When you plan changes, plan for cleanups.) On the Hotspot project, which is almost 1.5 decades old, we have often practiced and benefited from such etiquette. The process is, and should be, inductive, not prescriptive. An ounce of neighborliness is better than a pound of police-work. Reality check: If you actually look at (or live in) the Hotspot code base, you will find we have accumulated many annoying irregularities in our source base. I suppose this is the normal condition of a lived-in space. Unless you want to spend all your time polishing and tidying, you can't live without some smudge and clutter, can you? Final digression: Grammars and dictionaries and other prescriptive rule books are sometimes useful, but we humans learn and maintain our language by example not grammar. The same applies to style rules. Actually, I think the process of maintaining a clean and pleasant working code base is an instance of a community maintaining its common linguistic identity. BTW, I've been reading and listening to John McWhorter lately with great pleasure. (If you end with a digression, is it a tail-digression?)

• JavaScript Sucks.

  - by Matt Watson

  JavaScript Sucks. Yes, I said it. Microsoft's announcement of TypeScript got me thinking today. Is this a step in the right direction? It sounds like it fixes a lot of problems with JavaScript development. But is it really just duct tape and super glue for a programming model that needs to be replaced?I have had a love hate relationship with JavaScript, like most developers who would prefer avoiding client side code. I started doing web development over 10 years ago and I have done some pretty cool stuff with JavaScript. It has came a long ways and is the universal standard these days for client side scripting in the web browser. Over the years the browsers have become much faster at processing JavaScript. Now people are even trying to use it on the server side via node.js. OK, so why do I think JavaScript sucks?Well first off, as an enterprise web application developer, I don't like any scripting or dynamic languages. I like code that compiles for lots of obvious reasons. It is messy to code with and lacks all kinds of modern programming features. We spend a lot of time trying to hack it to do things it was never really designed for.Ever try to use different jQuery based plugins that require conflicting jQuery versions? Yeah, that sucks.How about trying to figure out how to make 20 javascript include files load quicker as one request? Yeah that sucks too.Performance? Let me just point to the old Facebook mobile app made with JS & HTML5. It sucked. Enough said.How about unit testing JavaScript? I've never tried it, but it sure sounds like fun.My biggest problem with JavaScript is code security. If I make some awesome product, there is no way to protect my code. How can we expect game makers to write apps in 100% JavaScript and HTML5 if they can't protect their intellectual property?There are compiling tools like Closure, unit test frameworks, minify, coffee script, TypeScript and a bunch of other tools. But to me, they all try to make up for the weaknesses and problems with JavaScript. JavaScript is a mess and we spend a lot of time trying to work around all of it's problems. It is possible to program in Silverlight, Java or Flash and run that in the browser instead of JavaScript, but they all have their own problems and lack universal mobile support. I believe Microsoft's new TypeScript is a step forward for JavaScript, but I think we need to start planning to go a whole different direction. We need a new universal client side programming model, because JavaScript sucks.

• SQLAuthority News – Weekend Experiment with NuoDB – Points to Pondor and Whitepaper

  - by pinaldave

  This weekend I have downloaded the latest beta version of NuoDB. I found it much improved and better UI. I was very much impressed as the installation was very smooth and I was up and running in less than 5 minutes with the product. The tools which are related to the Administration of the NuoDB seems to get makeover during this beta release. As per the claim they support now Solaris platform and have improved the native MacOS installation. I neither have Mac nor Solaris – I wish I would have experimented with the same. I will appreciate if anyone out there can confirm how the installations goes on these platforms. I have previously blogged about my experiment with NuoDB here: SQL SERVER – Weekend Project – Experimenting with ACID Transactions, SQL Compliant, Elastically Scalable Database SQL SERVER – Beginning NuoDB – Who will Benefit and How to Start SQL SERVER – Follow up on Beginning NuoDB – Who will Benefit and How to Start – Part 2 I am very impressed with the product so far and I have decided to understand the product further deep. Here are few of the questions which I am going to try to find answers with regards to NuoDB. Just so it is clear – NuoDB is not NOSQL, matter of the fact, it is following all the ACID properties of the database. If ACID properties are crucial why many NoSQL products are not adhering to it? (There are few out there do follow ACID but not all). I do understand the scalability of the database however does elasticity is crucial for the database and if yes how? (Elasticity is where the workload on the database is heavily fluctuating and the need of more than a single database server is coming up). How NuoDB has built scalable, elastic and 100% ACID compliance database which supports multiple platforms? How is NOSQL compared to NuoDB’s new architecture? In the next coming weeks, I am going to explore above concepts and dive deeper into the understanding of the same. Meanwhile I have read following white paper written by Experts at University of California at Santa Barbara. Very interesting read and great starter on the subject Database Scalability, Elasticity, and Autonomy in the Cloud. Additionally, my questions are also talking about NoSQL, this weekend I have started to learn about NoSQL from Pluralsight‘s online learning library. I will share my experience very soon.

• Ubuntu 11.10 running in windows 7 (wubi) AND on a separate partition

  - by Pareen

  I am in a very strange situation and need some help: I installed Ubuntu 11.10 through Wubi a while back so that I can use it alongside Windows 7. I was running out of space on my disk when trying to install applications. Without understanding how Wubi worked, I partitioned my C drive (creating a new 90 GB partition) in Windows, booted from the Ubuntu 11.10 install/live disk, and used the "something else" option to create a ext4 (setting the mount point to root) and swap space partitions (/sda5 and /sda6). After the install, my computer no longer boots with the previous Wubi menu and is now using the Linux grub. The options I have are /sda2, which boots Windows 7; /sda1, which doesn't do anything and reloads the same menu, and the run Linux options. So I now have Ubuntu running on a separate partition, as well as the original Wubi install. I want to delete the seperate partition and go back to running Ubuntu on Wubi...if I remove the partition will I need the Windows 7 disk to restore the boot loader? I dont have the Windows 7 disk on me so what is the best way to clean this up so I get rid of the seperate partition? -------------------------------------------------UPDATE----------------------------------------------------- ============================================================================================================ thank you so much for your response. Actually, it would be fantastic if I could migrate my Wubi install into the new partition because I had downloaded the AOSP on the Wubi install (as well as other files) and would love to preserve them. If i can do that and work on the new partition with the old files than that would be great, and I can worry about wiping out the partition completely later on i.e. when I have the windows disk or something. Can you tell me how to do this migration?? So when I select the /sda2, it loads up my Windows. If i click on the Linux, it loads up the newly install Linux (my files that were on the Wubi install aren't there) fine. If I click on the /sda1 (SYSTEM_DRIVE... this is what the Wubi was using to boot the menu that let me select Windows 7 or Ubuntu)... it fails and just reloads the original menu. Here is the link to my boot info script http://pastebin.com/dMrY0NL3

• ATI Radeon HD 4650 AGP Video card not recognized properly

  - by PastorLarry

  I have an ASUS ATI Radeon HD 4650 AGP in this system (yeah, I know how old it is). I've been on Ubuntu since 10.04, and the system has never properly recognized the card. I have always had the VESA drivers installed. Now that I have the time to address the problem, 12.04 was listing the card as "Unknown" under the System Settings. Meanwhile, Sysinfo recognizes the card as: Advanced Micro Devices [AMD] nee ATI RV730 Pro AGP [Radeon HD 4600 Series] (prog-if 00 [VGA controller]) Subsystem: ASUSTeK Computer Inc. Device 0028 So I know that this card should be using the radeon driver (or even the radeonhd driver). However, when I installed the mesa-utils package, the card is suddenly reported as: Gallium 0.4 on llvmpipe (LLVM 0x300) So now, I'm completely at a loss. It seems that the llvmpipe stuff has to do with OpenGL, but it still appears that I don't have the proper video driver installed. That being said, anyone know what I can do to force the system to recognize the card and use the radeon driver? [EDIT 05.28] I did look at some other information, including glxinfo and a couple of other commands (it was REALLY late, so I don't remember the other commands) and I got these: glxinfo | grep vendor: server glx vendor string: SGI client glx vendor string: Mesa Project and SGI OpenGL vendor string: X.org glxinfo | grep renderer: OpenGL renderer string: Gallium 0.4 on AMD RV730 One of the other commands gave a whole lot of info and near the end stated that the activation string for the radeon driver was "modprobe radeon". I've tried that from sudo and as root, but it doesn't seem to change anything. I'm at a complete loss. I've even added the xorg-edgers ppa to my Software Sources and updated and rebooted the system, but nothing has changed. Most of all, I can't seem to find any documentation on this issue, as it seems that it's assumed that the radeon driver will install automatically, no questions asked. I feel like such a newbie. Does anyone have any ideas on this? [edit 05.28] results of lsmod | grep radeon (in a more readable format than the comment below): radeon 733693 3 ttm 65344 1 radeon drm_kms_helper 45466 1 radeon drm 197692 5 radeon,ttm,drm_kms_helper i2c_algo_bit 13199 1 radeon [edit 05.29] This is my /etc/X11/xorg.conf: Section "ServerLayout" Identifier "aticonfig Layout" Screen 0 "aticonfig-Screen[0]-0" 0 0 EndSection Section "Module" EndSection Section "Monitor" Identifier "aticonfig-Monitor[0]-0" Option "VendorName" "ATI Proprietary Driver" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" EndSection Section "Device" Identifier "aticonfig-Device[0]-0" Driver "fglrx" BusID "PCI:1:0:0" EndSection Section "Screen" Identifier "aticonfig-Screen[0]-0" So here is my question. Can I simply change the name of the driver in the device section to "radeon" instead of "fglrx" and have the radeon driver work? Or is ther a way to use this as a tmeplate and change the appropriate lines and activate the radeon driver through this file?

• Fun with Sun Ray, 3D, Oracle VM x86 and SRIOV

  - by wim.coekaerts

  One of the things I like about my job is that I get to play around with stuff and make use of the technologies we work on in my teams. Sort of my own little playground. It allows me to study the products in great detail and put them to use in ways that individual product teams don't always intend them to be used for :) but that makes it fun. I have a lot of this set up at home because... work is sort of hobby and I just like to tinker with it. Anyway, a few weeks ago I was looking at my sun ray rig at home and how well 3D works. Google Earth and some basic opengl tests like glxspheres combined with virtualgl. It resulted in some very cool demos recorded with my little camera (sorry for the crappy quality of the video :-) : OVDC (soft client) on my mac Sun Ray 2FS Never mind the hickups during zoom, that's because I was using the scrollwheel on my mouse and I can't scroll uninterrupted :) Anyway, this is quite cool ! The setup for this was the following : Sun Ray on LAN, Sun Ray Server 5 latest installed on OL5.5 inside a VM running on Oracle VM 2.2 (hardware virt, with a virtual network (vif)) and the virtualgl rendering happened on another box (wopr5) that runs linux on a little atom D520 with an ION2 gpu. So network goes from Sun Ray to Sun Ray Server to wopr5 and back. Given that this is full screen 3D it puts a good amount of load on the network and it's pretty cool that SRS was just a VM :) So, separately, I had written a little blog entry about using sriov and oracle vm a while back. link to sriov blog entry Last night when I came home I wanted to do some more playing around with SRIOV and live migrate. To do this, I wanted to set up a VM with 2 network interfaces, one virtual network (vif) and then one that's one of the SRIOV virtual functions from my network card. Inside the guest they show as eth0 and eth1, and then bond them using a standard linux bonding device (bond0 here) with active active links. The goal here is that on live migrate, we would detach the VF (eth1 in guest in this case), the bond would then just hum along on eth0 (vif) we can live migrate the VM and then on the other server after the migrate completes we re-attach a VF to the VM there and eth1 pops up again and the bond uses both eth0/eth1 to do its work. So, to set this up, I figured, why not use my sun ray server VM because the 3D work generates a nice network load and is very latency/timing sensitive. In the end, I ran glxspheres on my sunray server (vm) displaying on my sun ray 2 fs and while that was running, I did my live migrate test of this vm (unplug pci VF, migrate, reconnect vf) and guess what, it just kept running :) veryyyyyy cool. now, it was supposed to, but it's always nice to see it actually work, for real. Here's a diagram of it. No gimics - just real technology at work ! enjoy :)

• SQL SERVER – Preserve Leading Zero While Coping to Excel from SSMS

  - by pinaldave

  Earlier I wrote two articles about how to efficiently copy data from SSMS to Excel. Since I wrote that post there are plenty of interest generated on this subject. There are a few questions I keep on getting over this subject. One of the question is how to get the leading zero preserved while copying the data from SSMS to Excel. Well it is almost the same way as my earlier post SQL SERVER – Excel Losing Decimal Values When Value Pasted from SSMS ResultSet. The key here is in EXCEL and not in SQL Server. The step here is to change the format of Excel Cell to Text from Numbers and that will preserve the value of the with leading or trailing Zeros in Excel. However, I assume this is done for display purpose only because once you convert column to Text you may find it difficult to do numeric operations over the column for example Aggregation, Average etc. If you need to do the same you should either convert the columns back to Numeric in Excel or do the process in Database and export the same value as along with it as well. However, I have seen in requirement in the real world where the user has to have a numeric value with leading Zero values in it for display purpose. Here is my suggestion, instead of manipulating numeric value in the database and converting it to character value the ideal thing to do is to store it as a numeric value only in the database. Whatever changes you want to do for display purpose should be handled at the time of the display using the format function of SQL or Application Language. Honestly, database is data layer and presentation is presentation layer – they are two different things and if possible they should not be mixed. If due to any reason you cannot follow above advise and you need is to have append leading zeros in the database only here are two of my previous articles I suggest you to refer them. I am open to learn new tricks as these articles are almost three years old. Please share your opinion and suggestions in the comments area.

• Installing Forms and Reports on a development system

  - by Duncan Mills

  By popular demand I've resurrected / updated one of the old blog postings from Jan Carlin's Blog on GroundSide here. A recent (lengthy) post on the Forms forums chronicles the problems some of you have had installing F&R on a development machine. See the link in the headline of this post for the main one. When installing, here are some points to bear in mind: Download and install Weblogic Server first. http://www.oracle.com/technology/software/products/middleware/index.htmlFind the Forms and Reports (and Disco and Portal) zip files here. Download them to the desktop (or some other temporary directory of your choosing). Unzip both of the two zip files into the same new directory (maybe called 'stage') and check that you have 4 directories in the stage dir when you are finished unzipping: 'Disk1', 'Disk2', 'Disk3' and 'Disk4'. These folders are specified in the zip file structure and must be preserved for the setup executable to work. If you use WinZip and have a right click menu option that say "Extract to here", use that by right click-dragging the zip file onto the newly created directory. Don't use the "Extract to folder %HOME%\Desktop\ofm_pfrd...disk_1of2" option. That will get you into the trouble that was reported early in this thread. Free up as much memory as you can. Stop services and background processes and virus scanners and databases (you don't need a DB to install Forms) and other things lurking about on your machine. You can restart them when the install is done. Around 1.5 GB free real memory should do it. If it doesn't, free up more if you can. Don't change the swap space unless you know what you are doing. Let Windows handle it. A 1 GB machine will likely not be enough. You will likely need at least 2GB of RAM.Start the install with setup.exe from the 'Disk1' directoryChoose the Install and Configure option unless you have a good reason not to.Choose a unique instance name even if you deinstalled and removed the last install. I suggest using 'asinst_20090722_1' (today's date in ISO format with a running incremented number at the end if you install more than two times on a particular day).Unselect Portal and Discoverer and select the Builders you want.Unselect WebCacheUnselect OHS.Unselect the single sign-on option Check for any failures and choose the retry option if any occur. If that doesn't fix the problem, call Oracle Customer Support .

• Freshen the RTS genre

  - by William Michael Thorley

  This isn't really a question, but a request for feedback. RPS (Rock, Paper, Scissors) RTS (Real Time Strategy) Demo version is out: The game is simple. It is an RTS. Why has it been made? Many if not most RTS’s are about economy and large numbers of unit types. The genre hasn’t actually developed the gameplay drastically from the very first RTS’s produced, some lesson have been learned, but the games are really very similar to how they have always been. RPS brings new gameplay to the RTS genre. Through three means: • New combat mechanics: RPS has two unique modes (as well as the old favourite) of resolving weapon fire. These change how combat happens, and make application of the correct units vital to success. From this comes the requirement to run Intel on your enemies. • Fixed Resource Economy: Each player has a fixed amount of energy, This means that there is a definite end to the game. You can attrition your enemy and try to outlast them, or try to outspend your opponent and destroy them. There is a limit to how fast ships can be built, through the generation of construction blocks, but energy is the fast limit on economy. • Game Modes: Game modes add victory conditions and new game pieces. The game is overseen by a controller which literally runs the game. Games are no longer line them up, gun them down. This means that new tactics must be played making skirmish games fresh with novel tactics without adding huge amounts of new game units to learn. I’ve produced RPS from the ground. I will be running a kickstarter in the near future, but right now I want feedback and input from the game developing community. Regarding the concepts, where RPS is going, the game modes, the combat mechanics. How it plays. RPS will give fresh gameplay to the genre so it must be right. It works over the internet or a LAN and supports single player games. Get it. Play it. Tell me about your games. Thank you Demo: https://dl.dropbox.com/u/51850113/RPS%20Playtest.zip Tutorials: https://dl.dropbox.com/u/51850113/RPSGamePlay.zip

• Should I choose Doctrine 2 or Propel 1.5/1.6, and why?

  - by Billy ONeal

  I'd like to hear from those who have used Doctrine 2 (or later) and Propel 1.5 (or later). Most comparisons between these two object relational mappers are based on old versions -- Doctrine 1 versus Propel 1.3/1.4, and both ORMs went through significant redesigns in their recent revisions. For example, most of the criticism of Propel seems to center around the "ModelName Peer" classes, which are deprecated in 1.5 in any case. Here's what I've accumulated so far (And I've tried to make this list as balanced as possible...): Propel Pros Extremely IDE friendly, because actual code is generated, instead of relying on PHP magic methods. This means IDE features like code completion are actually helpful. Fast (In terms of database usage -- no runtime introspection is done on the database) Clean migration between schema versions (at least in the 1.6 beta) Can generate PHP 5.3 models (i.e. namespaces) Easy to chain a lot of things into a single database query with things like useXxx methods. (See the "code completion" video above) Cons Requires an extra build step, namely building the model classes. Generated code needs rebuilt whenever Propel version is changed, a setting is changed, or the schema changes. This might be unintuitive to some and custom methods applied to the model are lost. (I think?) Some useful features (i.e. version behavior, schema migrations) are in beta status. Doctrine Pros More popular Doctrine Query Language can express potentially more complicated relationships between data than easily possible with Propel's ActiveRecord strategy. Easier to add reusable behaviors when compared with Propel. DocBlock based commenting for building the schema is embedded in the actual PHP instead of a separate XML file. Uses PHP 5.3 Namespaces everywhere Cons Requires learning an entirely new programming language (Doctrine Query Language) Implemented in terms of "magic methods" in several places, making IDE autocomplete worthless. Requires database introspection and thus is slightly slower than Propel by default; caching can remove this but the caching adds considerable complexity. Fewer behaviors are included in the core codebase. Several features Propel provides out of the box (such as Nested Set) are available only through extensions. Freakin' HUGE :) This I have gleaned though only through reading the documentation available for both tools -- I've not actually built anything yet. I'd like to hear from those who have used both tools though, to share their experience on pros/cons of each library, and what their recommendation is at this point :)

• Visual Studio 2010 RC &ndash; Silverlight 4 and WCF RIA Services Development - Updates from MIX Anno

  - by Harish Ranganathan

  MIX is happening and there is a lot of excitement around the various releases such as the Windows Phone 7 Developer Preview, IE9 Platform Preview and few other announcements that have been made.  Clearly, the Windows Phone 7 Developer Preview has generated the maximum interest and opened a plethora of opportunities for .NET Developers.  It also takes the mobile development to a new generation and doesn’t force developers to learn different programming language. Along with this, few other releases have been out.  The most anticipated Silverlight 4 RC is out and its corresponding templates are also out there for you to download.  Once VS 2010 RC was released, it was much of a disappointment that it doesn’t support SL4 development as well as the SL4 Business Application Development (a.k.a. WCF RIA Services).   There were few workarounds though nothing concrete.  Earlier I had written about how the WCF RIA Services Preview does work with ASP.NET Development using VS 2010 RC. However, with the release of SL4 RC and the corresponding tooling updates, one can develop for both SL4 as well as SL4 + WCF RIA Services using VS 2010 RC.  This is kind of important and keeps the continuum going until VS 2010 RTMs.  So, the purpose of this post is to quickly give the updates and links to install the relevant tools. Silverlight 4 RC Runtime Windows Runtime or the Mac Runtime Silverlight 4 RC Developer Tools for Visual Studio 2010 RC Silverlight 4 Tools for Visual Studio 2010 (this would install the Runtime as well automatically) Expression Blend 4 Beta Expression Blend 4 Beta If you install the SL4 RC Developer Tools, it also installs the WCF RIA Services Preview automatically.  You just need to install the WCF RIA Services Toolkit that can be downloaded from Install the WCF RIA Services Toolkit Of course you can also just install the WCF RIA Services for VS 2010 RC separately (without SL4 Tools) from here Kindly note, all the above mentioned links are with respect to Visual Studio 2010 RC edition.  If you are developing with VS 2008, then you can just target SL3 (as I write this, there seems to be no official support for developing SL4 with VS 2008) and the related tools can be downloaded from http://www.silverlight.net/getstarted/ Basically you need to download SL 3 Runtime, SDK, Expression Blend 3 and the Silverlight Toolkit.  All the links for the download are available in the above mentioned page. Also, a version of WCF RIA Services that is supported in VS 2008 is available for download at WCF RIA Services Beta for VS 2008 I know there are far too many things to keep in mind.  So, I put a flowchart that could help with depicting it pictorial.  Note that this is just my own imagination and doesn’t cover all scenarios.  for example, if you are neither developing for Webform, Silverlight, you end up nowhere whereas in actual scenario you may want to develop Desktop, Services, Console, Game and what not.  So, keep in mind this is just Web. Cheers !!!

• &ldquo;Our Users are Doing Something Surprising&rdquo;&hellip; but what?

  - by antonio romero

  I’ve just started a discussion on the OWB Linkedin Group based on a blog post from Laura Klein’s “Users Know” blog, entitled “Your Users are Doing Something Surprising”… As a PM I found the post thought-provoking and a good reminder to learn from our customers: ...You may have written user stories and work flows... But you know who didn’t read your user stories? That’s right: your users. The result? Somewhere out there, a whole lot of your users are doing something totally unexpected with your product.... Your customers want to do something with your product so badly that they’re going out of their way to come up with clever ways to do it on their own. There are three excellent reasons for you to know what your customers are actually doing with your product: So you know if you are missing an opportunity to pivot your product or marketing So you know if you are missing an important feature So you don’t accidentally destroy a commonly used workaround or "unplanned feature" Truer words were rarely blogged. In fact just in the last few weeks I have had several "users" (some customers, and some internal to Oracle, in fact) turn up having built unexpected but powerful things around OWB, because it has such extensibility mechanisms built into it: OMB*Plus, the old Java APIs back before 10.2, and now the code template/knowledge module framework OWB shares with ODI. Some of our external users show astounding knowledge of how to make OWB really sing. (We hope to feature case studies from several of them over the course of the year on the OWB blog.) My question to all of you: can you identify things you have done or are doing with OWB or that you depend on in it that you think would come as a surprise to us? This could be either some development so advanced as to leave us all gob-smacked, or just some common (to you) thing that you use it for that you find enormously valuable but that you think is a bit off the theoretical "main line" use case of loading data warehouses. I invite the readers of this blog to come visit the OWB and ODI LinkedIn group and share their unusual applications of OWB or the very ordinary-looking features that you don’t want us to forget or would like us to extend. Your anecdotes will impress the crowd and will also help shape future data integration products from Oracle... Come on, surprise us. :)

• Where to draw the line between development-led security and administration-led security?

  - by haylem

  There are cases where you have the opportunity, as a developer, to enforce stricter security features and protections on a software, though they could very well be managed at an environmental level (ie, the operating system would take care of it). Where would you say you draw the line, and what elements do you factor in your decision? Concrete Examples User Management is the OS's responsibility Not exactly meant as a security feature, but in a similar case Google Chrome used to not allow separate profiles. The invoked reason (though it now supports multiple profiles for a same OS user) used to be that user management was the operating system's responsibility. Disabling Web-Form Fields A recurrent request I see addressed online is to have auto-completion be disabled on form fields. Auto-completion didn't exist in old browsers, and was a welcome feature at the time it was introduced for people who needed to fill in forms often. But it also brought in some security concerns, and so some browsers started to implement, on top of the (obviously needed) setting in their own preference/customization panel, an autocomplete attribute for form or input fields. And this has now been introduced into the upcoming HTML5 standard. For browsers who do not listen to this attribute, strange hacks *\ are offered, like generating unique IDs and names for fields to avoid them from being suggested in future forms (which comes with another herd of issues, like polluting your local auto-fill cache and not preventing a password from being stored in it, but instead probably duplicating its occurences). In this particular case, and others, I'd argue that this is a user setting and that it's the user's desire and the user's responsibility to enable or disable auto-fill (by disabling the feature altogether). And if it is based on an internal policy and security requirement in a corporate environment, then substitute the user for the administrator in the above. I assume it could be counter-argued that the user may want to access non-critical applications (or sites) with this handy feature enabled, and critical applications with this feature disabled. But then I'd think that's what security zones are for (in some browsers), or the sign that you need a more secure (and dedicated) environment / account to use these applications. * I obviously don't deny the ingenuity of the people who were forced to find workarounds, just the necessity of said workarounds. Questions That was a tad long-winded, so I guess my questions are: Would you in general consider it to be the application's (hence, the developer's) responsiblity? Where do you draw the line, if not in the "general" case?

• Cross-platform independent development

  - by Joe Wreschnig

  Some years ago, if you wrote in C and some subset of C++ and used a sufficient number of platform abstractions (via SDL or whatever), you could run on every platform an indie could get on - Linux, Windows, Mac OS of various versions, obscure stuff like BeOS, and the open consoles like the GP2X and post-death Dreamcast. If you got a contract for a closed platform at some point, you could port your game to that platform with "minimal" code changes as well. Today, indie developers must use XNA to get on the Xbox 360 (and upcoming Windows phone); must not use XNA to work anywhere else but Windows; until recently had to use Java on Android; Flash doesn't run on phones, HTML5 doesn't work on IE. Unlike e.g. DirectX vs. OpenGL or Windows vs. Unix, these are changes to the core language you write your code in and can't be papered over without, basically, writing a compiler. You can move some game logic into scripts and include an interpreter - except when you can't, because the iPhone SDK doesn't allow it, and performance suffers because no one allows JIT. So what can you do if you want a really cross-platform portable game, or even just a significant body of engine and logic code? Is this not a problem because the platforms have fundamentally diverged - it's just plain not worthwhile to try to target both an iPhone and the Xbox 360 with any shared code because such a game would be bad? (I find this very unlikely. I can easily see wanting to share a game between a Windows Mobile phone and an Android, or an Xbox 360 and an iPad.) Are interfaces so high-level now that porting time is negligible? (I might believe this for business applications, but not for games with strict performance requirements.) Is this going to become more pronounced in the future? Is the split going to be, somewhat scarily, still down vendor lines? Will we all rely on high-level middleware like Flash or Unity to get anything cross-platform done? tl;dr - Is porting a problem, is it going to be a bigger problem in the future, and if so how do we solve it?

• Open the SQL Server Error Log with PowerShell

  - by BuckWoody

  Using the Server Management Objects (SMO) library, you don’t even need to have the SQL Server 2008 PowerShell Provider to read the SQL Server Error Logs – in fact, you can use regular old everyday PowerShell. Keep in mind you will need the SMO libraries – which can be installed separately or by installing the Client Tools from the SQL Server install media. You could search for errors, store a result as a variable, or act on the returned values in some other way. Replace the Machine Name with your server and Instance Name with your instance, but leave the quotes, to make this work on your system: [reflection.assembly]::LoadWithPartialName("Microsoft.SqlServer.Smo") $machineName = "UNIVAC" $instanceName = "Production" $sqlServer = new-object ("Microsoft.SqlServer.Management.Smo.Server") "$machineName\$instanceName" $sqlServer.ReadErrorLog() Want to search for something specific, like the word “Error”? Replace the last line with this: $sqlServer.ReadErrorLog() | where {$_.Text -like "Error*"} Script Disclaimer, for people who need to be told this sort of thing: Never trust any script, including those that you find here, until you understand exactly what it does and how it will act on your systems. Always check the script on a test system or Virtual Machine, not a production system. Yes, there are always multiple ways to do things, and this script may not work in every situation, for everything. It’s just a script, people. All scripts on this site are performed by a professional stunt driver on a closed course. Your mileage may vary. Void where prohibited. Offer good for a limited time only.

• Indie Software Developers - How do I handle taxes?

  - by Connor

  I apologize if this is the wrong site to post on, perhaps someone could point me to the proper place if it is not. Hello, I am 17 years old and currently develop applications/games for Android and iPhone as well as develop internet websites and code a variety of my own projects. I have been very fortunate and have made a large amount of money and continue to make money online to the point where I do not need a stable job, though I'd like to get one after college. I've never held a job anywhere, and have never had to pay taxes. I'm coming into a lot of issues and I am quite confused. I get money from MANY sources- 15 different advertisement networks(!), 4 different payment processors, 5 different affiliate networks and a variety of other sources. All of them pay to different places and at different times (checking account, PayPal, reloadable debit card, ect.) I essentially have a list in a Notepad with names and login information for each source. I have also created a PHP script that uses cURL to grab all the revenue from each service, add it all up, then text me every few hours so I can keep track. It's a mess, but it's working OK, and I can create custom reports (for IRS?). But enough of that, my questions are about taxes in the US, and how indie developers handle it all. I'm at slightly over $250k so far this year, with negligible earnings last year. I have it all stockpiled in a bank account and haven't touched it, I'm a bit scared to. What do I file as? A sole proprietor, a business, just a regular person? How can I handle all of the different revenue sources? (AdSense, CJ, LinkShare) So far none of them have sent me any paperwork on taxes and I've read that I'm supposed to pay taxes quarterly? Do I need paperwork from EACH source to file? Or can I just say I got $x total and that'd be it? What percentage do you pay of total earnings? Average? Should I create an LLC? A corporation? Or stay as a developer? What would be the cheapest options? Could I go to jail? I haven't touched the money except a few dollars to help my parents pay the mortgage once. Any insight would be great. My parents have no idea what I should do, both have no forms of higher education and both have no high school diploma's. They just live day by day with simple jobs. I appreciate any help or experience with this.

• I Choose iNada

  - by Mark Treadwell

  As a laptop and Kindle user, I have been looking at the usual cyclical Apple frenzy in the press with the same kind of amused tolerance I give my three-year-old son.  They never seem to learn, and they keep repeating the same things.  However when I ready articles like this, I am reminded that that is not always the case. I am a happy user of a monster-sized HP HDX laptop, HP touch screen all-in-one system, and multi-screen Dell desktops at home as well as a HP business laptop at work.  I have no iPod, iMac, iTouch or any other relationship with the company who wants to trademark the prefix “i”. I have not missed them. That is not to say that I have no technological gadgets.  I do.  They just do not dominate Every company wants to preserve their customer base, but Apple just does it too rigidly.  The buy-in necessary rubs me wrong.  When the fanboys scream about the next great iApple thing which will kill off another market segment (this time, the iPad will kill off laptops), the amused tolerance returns. From what I have seen, the iPad virtual keyboard is a poor substitute for an actual keyboard.  It was intended to let you get some kind of text into a device that is not really intended for keyboard input, but rather for touch manipulation of a designed interface.  I like the virtual keyboard on my LG Dare cell phone, but you will not catch me writing my next novel with it.  But, you hear, you can connect a real keyboard and get info from another computer.  That is when you realize that the iPad is not a true standalone device like a laptop.  You have to make more hardware purchases to get what you truly want.  It is an expensive accommodation to get you a different form of freedom. So if Apple made a product with me in mind, you can have it.  Everyone gets to make their own choice.  My choice is the iNada.

• Is commented out code really always bad?

  - by nikie

  Practically every text on code quality I've read agrees that commented out code is a bad thing. The usual example is that someone changed a line of code and left the old line there as a comment, apparently to confuse people who read the code later on. Of course, that's a bad thing. But I often find myself leaving commented out code in another situation: I write a computational-geometry or image processing algorithm. To understand this kind of code, and to find potential bugs in it, it's often very helpful to display intermediate results (e.g. draw a set of points to the screen or save a bitmap file). Looking at these values in the debugger usually means looking at a wall of numbers (coordinates, raw pixel values). Not very helpful. Writing a debugger visualizer every time would be overkill. I don't want to leave the visualization code in the final product (it hurts performance, and usually just confuses the end user), but I don't want to loose it, either. In C++, I can use #ifdef to conditionally compile that code, but I don't see much differnce between this: /* // Debug Visualization: draw set of found interest points for (int i=0; i<count; i++) DrawBox(pts[i].X, pts[i].Y, 5,5); */ and this: #ifdef DEBUG_VISUALIZATION_DRAW_INTEREST_POINTS for (int i=0; i<count; i++) DrawBox(pts[i].X, pts[i].Y, 5,5); #endif So, most of the time, I just leave the visualization code commented out, with a comment saying what is being visualized. When I read the code a year later, I'm usually happy I can just uncomment the visualization code and literally "see what's going on". Should I feel bad about that? Why? Is there a superior solution? Update: S. Lott asks in a comment Are you somehow "over-generalizing" all commented code to include debugging as well as senseless, obsolete code? Why are you making that overly-generalized conclusion? I recently read Robert Glass' "Clean Code", which says: Few practices are as odious as commenting-out code. Don't do this!. I've looked at the paragraph in the book again (p. 68), there's no qualification, no distinction made between different reasons for commenting out code. So I wondered if this rule is over-generalizing (or if I misunderstood the book) or if what I do is bad practice, for some reason I didn't know.

• Unity desktop "smears" (doesn't refresh) and shows no wallpaper

• Live Debugging

  - by Daniel Moth

  Based on my classification of diagnostics, you should know what live debugging is NOT about - at least according to me :-) and in this post I'll share how I think of live debugging. These are the (outer) steps to live debugging Get the debugger in the picture. Control program execution. Inspect state. Iterate between 2 and 3 as necessary. Stop debugging (and potentially start new iteration going back to step 1). Step 1 has two options: start with the debugger attached, or execute your binary separately and attach the debugger later. You might say there is a 3rd option, where the app notifies you that there is an issue, referred to as JIT debugging. However, that is just a variation of the attach because that is when you start the debugging session: when you attach. I'll be covering in future posts how this step works in Visual Studio. Step 2 is about pausing (or breaking) your app so that it makes no progress and remains "frozen". A sub-variation is to pause only parts of its execution, or in other words to freeze individual threads. I'll be covering in future posts the various ways you can perform this step in Visual Studio. Step 3, is about seeing what the state of your program is when you have paused it. Typically it involves comparing the state you are finding, with a mental picture of what you thought the state would be. Or simply checking invariants about the intended state of the app, with the actual state of the app. I'll be covering in future posts the various ways you can perform this step in Visual Studio. Step 4 is necessary if you need to inspect more state - rinse and repeat. Self-explanatory, and will be covered as part of steps 2 & 3. Step 5 is the most straightforward, with 3 options: Detach the debugger; terminate your binary though the normal way that it terminates (e.g. close the main window); and, terminate the debugging session through your debugger with a result that it terminates the execution of your program too. In a future post I'll cover the ways you can detach or terminate the debugger in Visual Studio. I found an old picture I used to use to map the steps above on Visual Studio 2010. It is basically the Debug menu with colored rectangles around each menu mapping the menu to one of the first 3 steps (step 5 was merged with step 1 for that slide). Here it is in case it helps: Stay tuned for more... Comments about this post by Daniel Moth welcome at the original blog.
