  • RIM's current BB7 developer toolset is a joke

    - by mbrit
    tl;dr - RIM's current developer toolset is not fit for purpose.Background to this is that I'm currently working on a PhoneGap/Cordova project for a client that has to run on BlackBerry. The tooling is so ridiculous to use that even though I had a gentle dig at them in a Guardian piece it's worth having a more full-on attack.At the moment, RIM's pitch is that apps are built for the current BBOS7 devices using WebWorks. This is an HTML-based toolset. Essentially a browser is spun up in a native app container and your app is powered by JavaScript. Specific JavaScript libraries exist that thunk down to native capabilities no the device. I happen to use PhoneCap/Cordova in combination with this.The tooling is non-existent. I'm using TextMate, Ant, and Terminal to develop the app. There's no "console.log" output, and no debugging. The only way to instrument the app is to put "alert" calls in your code.Apart from the fact that that's *not* fine in 2012, how about this… every time you deploy a new app to the device, the device has to reboot. This process takes six minutes on a relatively modern BlackBerry device. How about this as well - in order to get a file into the package it has to be signed. My small app over here has 100 different files (75 or so generated). Signing doesn't happen locally, it happens on RIM's servers in Waterloo. Thus whenever you deploy the app you have this utility have to call RIM's servers 100 times. More to the point, sometimes during the day these servers have "micro-downtime" moments where they're unreachable for five or ten minutes, normally two or three times a day. Oh yes, you'll also get an email sent to you per signing on success or failure. 100 inbound emails, per deployment.(I started this post at the beginning of one of these cycles, by the way. That's how long it takes to build and deploy *once*. By the way, the change I made didn't work.)To clarify:* Change the script,* Build it using Ant,* Ant will spin up a Java app that talks to RIM's servers to sign it.* Receive 100 emails, assuming the server is up.* App deployed - takes about 30 seconds.* BlackBerry device restarts - takes about six minutes.* Find and open the app. Go through security prompts.* Test the app, with no "console.log" output and no debugger."Why not use the simulator?" I hear you ask. Well, apart from the fact that the simulator refused to reach any network service over HTTPS that I happen to own? (Some people suggest changing DNS settings for this known issue.) Admittedly, the simulator does show you console.log, but you still have the "six minute" restart issue on the simulator.Developers will understand this problem. Breaking concentration for six-plus minutes every time you want to deploy an app turns developing into a nightmare. Combining that with no worthy debugging tools turns the toolset into a joke.

  • Project of Projects with team Foundation Server 2010

    - by Martin Hinshelwood
    It is pretty much accepted that you should use Areas instead of having many small Team Projects when you are using Team Foundation Server 2010. I have implemented this scenario many times and this is the current iteration of layout and considerations. If like me you work with many customers you will find that you get into a grove for how to set these things up to make them as easily understandable for everyone, while giving the best functionality. The trick is in making it as intuitive as possible for both you and the developers that need to work with it. There are five main places where you need to have the Product or Project name in prominence of any other value. Area Iteration Source Code Work Item Queries Build Once you decide how you are doing this in each of these places you need to keep to it religiously. Evan if you have one source code file to keep, make sure it is in the right place. This makes your developers and others working with the format familiar with where everything should go, as well as building up mussel memory. This prevents the neat system degenerating into a nasty mess. Areas Areas are traditionally used to separate out parts of your product / project so that you can see how much effort has gone into each. Figure: The top level areas are for reporting and work item separation There are massive advantages of using this method. You can: move work from one project to another rename a project / product It is far more likely that a project or product gets renamed than a department. Tip: If you have many projects, over 100, you should consider categorising them here, but make sure that the actual project name always sits at the same level so you know which is which. Figure: Always keep things that are the same at the same level Note: You may use these categories only at the Area/Iteration level to make it easier to select on drop down lists. You may not want to use them everywhere. On the other hand, for consistency it would be better to. Iterations Iterations are usually used to some sort of time based consideration. Here I am splitting into Iterations with periodic releases. Figure: Each product needs to be able to have its own cadence The ability to have each project run at its own pace and to enable them to have their own release schedule is often of paramount importance and you don’t want to fix your 100+ projects to all be released on the same date. Source Code Having a good structure for your source even if you are not branching or having multiple products under the same structure is always a good idea. Figure: Separate out your products source You need to think about both your branches as well as the structure of your source. All your code should be under “Source” and everything you need to build your solution including Build Scripts and 3rd party tools should be under your “Main” (branch) folder. This should them be branched by “Quality”, “Release” or both to get the most out of your branching structure. The important thing is to make sure you branch (or be able to branch) everything you need to build, test and deploy your application to an environment. That environment may be development, test or even production, but I can’t stress the importance of having everything your need. Note: You usually will not be able to install custom software on your build server. Store any *.dll’s or *.exe’s that you need under the “Tools\Tool1” folder. Note: Consult the Branching Guidance for Team Foundation Server 2010 for more on branching Figure: Adding category may be a necessary evil Even if you have to have a couple of categories called “Default”, it is better than not knowing the difference between a folder, Product and Branch. Work Item Queries Queries are used to load lists of Work Items out of TFS so you can see what work you have. This means that you want to also separate queries out by Product / project to make it easier to Figure: Again you have the same first level structure Having Folders also in Work Item Tracking we do the same thing. We put all the queries under a folder named for the Product / Project and change each query to have “AreaPath=[TeamProject]\[ProductX]” in the query instead of the standard “Project=@Project”. Tip: Don’t have a folder with new queries for each iteration. Instead have a single “Current” folder that has queries that point to the current iteration. Just change the queries as you move from one iteration to another. Tip: You can ctrl+drag the “Product1” folder to create your “Product2” folder. Builds You may have many builds both for individual products but also for different quality's. This can be further complicated by having some builds that action “Gated Check-In” and others that are specifically for “Release”, “Test” or another purpose. Figure: There are no folders, yet, for the builds so you need a good naming convention Its a pity that there are no folders under builds, some way to categorise would be nice. In lue of that at the moment you can use a functional naming convention that at least allows you to find what you want. Conclusion It is really easy to both achieve and to stick to this format if you take the time to do it. Unless you have 1000+ builds or 100+ Products you are unlikely run into any issues. Even then there are things you can do to mitigate the issues and I have describes some of them above. Let me know if you can think of any other things to make this easier.

  • Seven Random Thoughts on JavaOne

    - by HecklerMark
    As most people reading this blog may know, last week was JavaOne. There are a lot of summary/recap articles popping up now, and while I didn't want to just "add to pile", I did want to share a few observations. Disclaimer: I am an Oracle employee, but most of these observations are either externally verifiable or based upon a collection of opinions from Oracle and non-Oracle attendees alike. Anyway, here are a few take-aways: The Java ecosystem is alive and well, with a breadth and depth that is impossible to adequately describe in a short post...or a long post, for that matter. If there is any one area within the Java language or JVM that you would like to - or need to - know more about, it's well-represented at J1. While there are several IDEs that are used to great effect by the developer community, NetBeans is on a roll. I lost count how many sessions mentioned or used NetBeans, but it was by far the dominant IDE in use at J1. As a recent re-convert to NetBeans, I wasn't surprised others liked it so well, only how many. OpenJDK, OpenJFX, etc. Many developers were understandably concerned with the change of sponsorship/leadership when Java creator and longtime steward Sun Microsystems was acquired by Oracle. The read I got from attendees regarding Oracle's stewardship was almost universally positive, and the push for "openness" is deep and wide within the current Java environs. Few would probably have imagined it to be this good, this soon. Someone observed that "Larry (Ellison) is competitive, and he wants to be the best...so if he wants to have a community, it will be the best community on the planet." Like any company, Oracle is bound to make missteps, but leadership seems to be striking an excellent balance between embracing open efforts and innovating in competitive paid offerings. JavaFX (2.x) isn't perfect or comprehensive, but a great many people (myself included) see great potential, are developing for it, and are really excited about where it is and where it may be headed. This is another part of the Java ecosystem that has impressive depth for being so new (JavaFX 1.x aside). If you haven't kicked the tires yet, give it a try! You'll be surprised at how capable and versatile it is, and you'll probably catch yourself smiling while coding again.  :-) JavaEE is everywhere. Not exactly a newsflash, but there is a lot of buzz around EE still/again/anew. Sessions ranged from updated component specs/technologies to Websockets/HTML5, from frameworks to profiles and application servers. Programming "server-side" Java isn't confined to the server (as you no doubt realize), and if you still consider JavaEE a cumbersome beast, you clearly haven't been using the last couple of versions. Download GlassFish or the WebLogic Zip distro (or another JavaEE 6 implementation) and treat yourself. JavaOne is not inexpensive, but to paraphrase an old saying, "If you think that's expensive, you should try ignorance." :-) I suppose it's possible to attend J1 and learn nothing, but you'd have to really work at it! Attending even a single session is bound to expand your horizons and make you approach your code, your problem domain, differently...even if it's a session about something you already know quite well. The various presenters offer vastly different perspectives and challenge you to re-think your own approach(es). And finally, if you think the scheduled sessions are great - and make no mistake, most are clearly outstanding - wait until you see what you pick up from what I like to call the "hallway sessions". Between the presentations, people freely mingle in the hallways, go to lunch and dinner together, and talk. And talk. And talk. Ideas flow freely, sparking other ideas and the "crowdsourcing" of knowledge in a way that is hard to imagine outside of a conference of this magnitude. Consider this the "GO" part of a "BOGO" (Buy One, Get One) offer: you buy the ticket to the "structured" part of JavaOne and get the hallway sessions at no additional charge. They're really that good. If you weren't able to make it to JavaOne this year, you can still watch/listen to the sessions online by visiting the JavaOne course catalog and clicking the media link(s) in the right column - another demonstration of Oracle's commitment to the Java community. But make plans to be there next year to get the full benefit! You'll be glad you did. All the best,Mark P.S. - I didn't mention several other exciting developments in areas like the embedded space and the "internet of things" (M2M), robotics, optimization, and the cloud (among others), but I think you get the idea. JavaOne == brainExpansion;  Hope to see you there next year!

  • Configuring the iPlanet as web tier for Oracle WebCenter Content (UCM)

    - by Adao Junior
    If you are looking for configure the iPlanet as Web server/proxy to use with the Oracle WebCenter Content, you probably won’t found an specific documentation for that or will found some old complex notes related to the old 10gR3. This post will help you out with few simple steps. That’s the diagram of the test scenario, considering that you will deploy in production in an cluster environment. First you need the software, for our scenario you will need: - Oracle iPlanet Web Server 7.0.15+ (Installed) - Oracle WebCenter Content 11gR1 PS5 (Installed) - Oracle WebLogic Web Server Plugins 11g (1.1) - Supported JDK (Using Oracle Java JDK 7u4 for the test) - Certified Client OS - Certified Server OS (Using Oracle Solaris 11 for the test) - Certified Database (Using Oracle Database 11.2.0.3 for the test) Then the configuration: - Download the latest plugin: http://www.oracle.com/technetwork/middleware/ias/downloads/wls-plugins-096117.html - Extract the WLSPlugin11g-iPlanet7.0 in some folder, like <iPlanet_Home>/plugins/wls11 - Include the plugin reference to the magnus.conf: If Unix (Solaris or Linux), include the line: Init fn="load-modules" shlib="/apps/oracle/WebServer7/plugins/wls11/lib/mod_wl.so" If Windows, Include the line:        Init fn="load-modules" shlib="D:\\oracle\\WebServer7\\plugins\\wls11\\lib\\mod_wl.dll" - Include the proxy reference to the obj.conf of each instance: <Object name="weblogic" ppath="*/cs/*"> Service fn="wl-proxy" WebLogicCluster="wcc-node1:16201,wcc-node2:16202, wcc-node3:16203" </Object>   <Object name="weblogic" ppath="*/_dav/*"> Service fn="wl-proxy" WebLogicCluster="wcc-node1:16201,wcc-node2:16202, wcc-node3:16203" </Object>   <Object name="weblogic" ppath="*/_ocsh/*"> Service fn="wl-proxy" WebLogicCluster="wcc-node1:16201,wcc-node2:16202, wcc-node3:16203" </Object>   <Object name="weblogic" ppath="*/adfAuthentication/*"> Service fn="wl-proxy" WebLogicCluster="wcc-node1:16201,wcc-node2:16202, wcc-node3:16203" </Object> If you are using an single node setup, change the Service fn=…. line to something like: Service fn="wl-proxy" WebLogicHost=<wcc-server> WebLogicPort=16200 With these configurations, your should have the WebCenter Content UI working with the iPlanet, test it. [http://<web-server>/cs/] With the UI working, the last step is to configure the WebDav: - Go to the iPlanet Admin Console (usually https://<web-server>:8989) - Go to Configurations >> [instance] >> Virtual Servers >> [Virtual Server] >> WebDAV: - Click New - Populate the URI with /cs/idcplg/webdav: - Select “Anyone (No Authentication)”, the wc Content will take care of the security: This will allow you to use the WebDav feature and the Desktop Integration Suite, including double-byte characters. Anothers iPlanet tunes could be done, I can cover in the next post related to the iPlanet. Cross-posted on the ContentrA.com Blog Related posts:  - Using a Web Proxy Server with WebCenter Family

  • Cannot get 3D OpenGL support in Vmware guests, how can I fix this?

    - by jjapol
    I have been working at this problem for 2 days now. I cannot for the life of me enable 3D support in VMWare 9 guests. My specifications are: Hardware: Dell Latitude E5520 laptop. Processor: Intel i7-2620M CPU @ 2.70GHz × 4. Memory: 8GB. Video: Intel Sandybridge Mobile x86/MMX/SSE2 OS: Ubuntu 12.04.1 LTS, 32 bit. Vmware Workstation: 9.0.1 build-894247 Glxgears functions fine. Frame rate is ~60fps. Vmware guest: Windows 7 Starting the Windows 7 guest in VMware throws the following errors: No 3D support is available from the host. and Hardware graphics acceleration is not available. I've read through this VMware forum thread, but again the hardware in the post is different (nVidia). I've followed the instructions at this Ask Ubuntu post as closely as possible as the question is nearly the same as mine although my hardware is different. Answer 1 regarding setting mks.gl.allowBlacklistedDrivers = TRUE; in my vmx configuration file causes the VM to crash when it starts. The second answer I followed as closely as possible. I uninstalled VMware, Did sudo apt-get install build-essential linux-headers-$(uname -r) at a terminal, Added the PPA https://launchpad.net/~glasen/+archive/intel-driver, Then at a terminal did sudo apt-get update && sudo apt-get upgrade -y I reinstalled VMware and have the same results: no 3D in guests. I'm getting the feeling that something is awry with the Sandy Bridge driver, but I can't seem to come up with any solutions. Has anyone out there run across this problem also? By the way, the operation of the likes of Solidworks and AutoCad within a Windpws 7 guest does appear to be improved in VMware 9 vs VMware 8 in spite of the fact that 3D support is lacking in the Windows 7 guest. I'd also add that my glxinfo file was nearly identical to the glxinfo file posted at askubuntu.com/questions/181829/…. I had a total of seven minor differences per a comparison using Meld. –

  • Full disk encryption with seperate boot and encrypted keyfile storage: Two-Form Authentication

    - by Cain
    I am trying to setup true Full Disk encryption with two-form authentication on 12.04 and can not find out how to call a keyfile for the encrypted root out of another encrypted partition. All documentation or questions I am finding for whole or full disk encryption only encrypts separate partitions on the same disk. This is not what most are calling full disk encryption, /boot is not on a partition on the root drive, rather it is on a usb stick as sdx1. Instead root is on a logical partition on top of a LUKS container. Luks is run on the whole disk, encrypting the partition table as well. All drives in the machine are completely encrypted and to open it it requires a USB drive (what I have) as well as a passphrase (what I know) resulting in Two-Form Authentication to boot the machine. Device sdx cryptroot vg00 lvroot / There is no passphrase to open the encrypted root device, only a keyfile. That keyfile is kept on the usb drive with /boot, in its own encrypted partition (I'll call this cryptkey). In order for the root file system (cryptroot) to be opened, initramfs must ask for the passphrase to cryptkey on the usb drive, then use the keyfile inside that to open cryproot. I did manage to find what I think is the how-to I used to do this once before: http://wiki.ubuntu.org.cn/UbuntuHelp:FeistyLUKSTwoFormFactor I already have the system installed and can chroot into it, however, I can not get it to call for the keys on the USB during boot. I did find a how-to saying I needed to make a cryptroot conf for initramfs but, I believe that is for a passphrase: https://help.ubuntu.com/community/EncryptedFilesystemLVMHowto#Notes_for_making_it_work_in_Ubuntu_12.04_.22Precise_Pangolin.22_amd64 I also tried to setup crypttab. However, crypttab only works for drives mounted after the root drive as calling for a keyfile on a device not yet mounted to the system doesnt work. The Feisty how-to included scripts that would be run during boot instructing initramfs to mount the usb drive temporarily and call the keyfile for root which worked quite well except those scripts are outdated now, many of the things they relied on have been merged into something else, changed, or simply don't exist anymore. If I have missed a clear how-to for this, that would be wonderful, I just don't think I have.

  • Oracle OpenWorld Call for MDM Papers

    - by david.butler(at)oracle.com
    As the MDM Track owner, I would like to invite everyone to respond to the Oracle OpenWorld (October 2-6, Moscone Center, San Francisco) Call for Papers (https://oracleus.wingateweb.com/portal/cfp/ ). The Call for Papers is open now through Sunday, March 27. This is an outstanding opportunity for organizations familiar with MDM to tell their story to a very large, knowledgeable and intensely interested community. Opportunities for feedback and networking abound.  I would love to see MDM papers on: business drivers; business benefits; quantified ROI stories; business process optimization; implementation styles; implementation lessons learned; using master data as a service; data governance best practices; end-to-end data quality experiences; support for SOA; Chart of Accounts issues fixed; how to leverage reference data; improving EPM and/or BI across the board; operationalizing a data warehouse; support for cloud computing; compliance success stories; architecture, scalability, and mixed workload RAC platform performance examples; industry specific value propositions (Financial Services; Retail, Telecom; Manufacturing, High Tech Manufacturing, Public Sector, Health Care, …); and line of business specific value propositions (CRM, ERP, PLM, SCM, …); etc. In fact, given that MDM positively impacts all areas of operations and analytics, there are no limits to the ideas you may have for an OpenWorld presentation. When you follow the submission process, be sure to use “Master Data Management” for either the Primary or Optional track. Add “Master Data Management” as an Optional track if you are adding MDM content to a presentation on one of the following tracks: Agile; Customer Relationship Management, Oracle E-Business Suite, Product Lifecycle Management, Siebel, Sourcing and Procurement, Supply Chain Management, or one of the 18 available industry tracks. If Cloud Computing is included, please add “Cloud Computing” as a Cross-Stream Track. And don’t forget to make “MDM” a Tag, along with Business Intelligence, Cloud, CRM, Data Integration, Data Migration, Data Warehousing, EPM, or Service-Oriented Architecture whenever your content includes these items. I will personally review each submission. I hope you all keep me very busy over the next few weeks.

  • Bridging 10GbE with 12.04 - bridging works but the bridging computer has no internet access

    - by Donal
    I have been trying to get 12.04 bridging working with two 10GbE cards. I have 2 10GbE cards in a linux box being used only for this bridge, 1 with 2 10GbaseT ports and another with a single CX4 port. I have 2 client computers connected with 10GbaseT cards and the CX4 card connects to a procurve switch. I can get the bridging happening mostly the way that I want, The clients receive dhcp information from the dhcp server (not the bridging machine) and can connect to and properly see the rest of the network. Speeds are ok, not amazing but working on that is another matter. My problem is that the bridging machine has no internet access ... meaning I can't update anything or apt-get anything It can ping all other machines on the local network. I've tried the helpful hints from: https://help.ubuntu.com/community/NetworkConnectionBridge "Enabling Internet Use on the Bridging Computer" and get the following RTNETLINK answers: File exists but dhclient br0 does nothing for me :( I think if it is anything it a multiple route problem as both br0 and eth4 have ipaddresses ... even though I have only set it up so that br0 has one ...

  • WebAPI and MVC4 and OData

    - by Aligned
    I was looking closer into WebAPI, specificially how to use OData to avoid writing GetCustomerByCustomerId(int id) methods all over the place. I had problems just returning IQueryable<T> as some sites suggested in the WebpAPI (Assembly System.Web.Http.dll, v4.0.0.0).  I think things changed in the release version and the blog posts are still out of date. There is no [Queraable] as the answer to this question suggests. Once I get WebAPI.Odata Nuget package, and added the [Queryable] to the method http://localhost:57146/api/values/?$filter=Id%20eq%201 worked (don’t forget the ‘$’). Now the main question is whether I should do this and how to stop logged in users from sniffing the url and getting data for other users. I John V. Peterson has a post on securing WebAPI with headers and intercepting the call at that point. He had an update to use HttpMessageHandlers instead. I think I’ll use this to force the call to contain some kind of unique code for the user, but I’m still thinking about this. I will not expose this to the public, just to my calls with-in my Forms Authentication areas. Other links: http://robbincremers.me/2012/02/16/building-and-consuming-rest-services-with-asp-net-web-api-and-odata-support/ ~lots of good information John V Peterson example: https://github.com/johnvpetersen/ASPWebAPIExample ~ all data access goes through the WebApi and the web client doesn’t have a connection string ~ There is code library for calling the WebApi from MVC using the HttpClient.

  • Live CD has black screen HP DV6

    - by Shaun Killingbeck
    Attempting to install/try ubuntu (11.10, 12.04) on my new laptop, using a liveCD (and tried USB). I get the purple screen (with the man/keyboard at the bottom) and after that the screen flashes bright white before going black. Ubuntu continues to load in the background, with login sound etc but the screen is off. I have tried as many different solutions as I could find including: using nomodestep, xforcevesa, i915.modeset=0, and also now i915.modeset=1 in boot options (seperately): varying consequences, but either I end up at a blinking cursor with no prompt, a command line (startx fails: no screen found), or the original blank screen again Tried booting from VirtualBox - it crashes at the same place the screen would go blank when using a CD/USB tried 11.04: I don't have this problem BUT when trying to install, I get a ubi-partman error 141 (possibly down to the three partitions that came on my laptop... not sure why HP needed there own separate partition for HP Tools...) Model: HP Pavillion DV6 6B08SA Processor: AMD Quad-Core A6-3410MX APU with Radeon HD 6545G2 Dual Graphics (1.6 GHZ 4 MB L2 cache ) Chipset: AMD RS880M Any help would be greatly appreciated. I just want to be able to partition the drive and install Ubuntu. I'm assuming the issue is graphics card related, although I have no confirmation of that. Update: Tried the ?orkarounds on https://wiki.ubuntu.com/X/Troubleshooting/BlankScreen - set gfxpayload=text changed nothing, removing splash did nothing and setting vesafb.nonsense=1 did nothing either. I'd like to be able to collect some log information somehow, but I can't get to a command line from the liveCD. tried using the latest 12.04 beta, same issue tried nomodeset without splash or quiet. get the following (tail of) output before it freezes on that screen: * Starting configure network device security [OK] * Starting configure network device [OK] [ 25.720899] ieee80211 phy0: w1_ops_config: change monitor mode: false (implement) [ 25.720923] ieee80211 phy0: w1_ops_config: change power-save mode: false (implement) * Starting restore sound card(s') mixer state(s) [fail] [ 25.721849] ieee80211 phy0: w1_ops_bss_info_changed: qos enabled: false (implement) * Stopping save kernel messages [OK] * Starting bluetooth [OK] * PulseAudio configured for per-user sessions saned disabled; edit /etc/default/saned [ 25.988016] hci_cmd_timer: hci0 command tx timeout [ 26.207225] bad LUN (0:1) [ 26.223735] bad target number (1:0) [ 26.252111] bad target number (2:0) [ 26.272170] bad target number (3:0) [ 26.300154] bad target number (4:0) [ 26.328162] bad target number (5:0) [ 26.344180] bad target number (6:0) [ 26.368142] bad target number (7:0) * Checking battery state...

    Originally posted on: http://geekswithblogs.net/stun/archive/2014/06/04/asp.net-vnext-blog-post-series.aspxASP.NET vNext Blog Post Series ASP.NET vNext was announced at TechEd 2014, and I have been playing around with it a bit. ASP.NET vNext is an exciting and revolutionary change for the Microsoft .NET development platform. ASP.NET vNext is now open-source, and available on Github at this location: https://github.com/aspnet/Home. I want to start a blog post series on the ASP.NET vNext, and share my experience as I learn more about it. Keeping it simple Each blog post in the series will be short and simple so I can write them in a short amount of time, and keep it focused on one (at most two) topic(s) per post. My goal is to make it easy to absorb the information as there are a ton of great new stuff to cover. Many other people in the community have blogged about the key new features of the ASP.NET vNext. I will link to those blog posts in my next blog post. MVC 6 POCO Controller Today, I want to start this blog post series with a teaser code snippet for those developers familiar with the ASP.NET MVC. Getting Started with ASP.NET MVC 6 article from ASP.NET website shows how to write a lightweight POCO (plain-old CLR object) MVC Controller class in the upcoming ASP.NET MVC 6. However, it doesn't show us how to use the IActionResultHelper interface to render a View. This is how I wrote my POCO MVC Controller based on the https://github.com/aspnet/Home/blob/master/samples/HelloMvc/Controllers/HomeController.cs sample from Github.   Note that this may not be the best way to write it, but this is good enough for now. using Microsoft.AspNet.Mvc; using Microsoft.AspNet.Mvc.ModelBinding; using MvcSample.Web.Models; namespace MvcSample.Web { public class HomeController { IActionResultHelper html; IModelMetadataProvider mmp; public HomeController(IActionResultHelper h, IModelMetadataProvider mmp) { this.html = h; this.mmp = mmp; } public IActionResult Index() { var viewData = new ViewDataDictionary<User>(mmp) { Model = User() }; return html.View("Index", viewData); } public User User() { return new User { Name = "My name", Address = "My address" }; } } } Please feel free to give me feedback as this will greatly help me organize the blog posts in this series, and plan head.

  • Setting up port forwarding for 7000 appliance VM in VirtualBox

    - by uejio
    I've been using the 7000 appliance VM for a lot of testing lately and relied on others to set up the networking for the VM for me, but finally, I decided to take the dive and do it myself.  After some experimenting, I came up with a very brief number of steps to do this all using the VirtualBox CLI instead of the GUI. First download the VM image and unpack it somewhere.  I put it in /var/tmp. Then, set your VBOX_USER_HOME to some place with lots of disk space and import the VM: export VBOX_USER_HOME=/var/tmp/MyVirtualBoxVBoxManage import /var/tmp/simulator/vbox-2011.1.0.0.1.1.8/Sun\ ZFS\ Storage\ 7000.ovf (go get a cup of tea...) Then, set up port forwarding of the VM appliance BUI and shell:First set up port as NAT:VBoxManage modifyvm Sun_ZFS_Storage_7000 --nic1 nat Then set up rules for port forwarding (pick some unused port numbers):VBoxManage modifyvm Sun_ZFS_Storage_7000 --natpf1 "guestssh,tcp,,4622,,22"VBoxManage modifyvm Sun_ZFS_Storage_7000 --natpf1 "guestbui,tcp,,46215,,215" Verify the settings using:VBoxManage showvminfo Sun_ZFS_Storage_7000 | grep -i nic Start the appliance:$ VBoxHeadless --startvm Sun_ZFS_Storage_7000 & Connect to it using your favorite RDP client.  I use a Sun Ray, so I use the Sun Ray Windows Connector client: $ /opt/SUNWuttsc/bin/uttsc -g 800x600 -P <portnumber> <your-hostname> & The portnumber is displayed in the output of the --startvm command.(This did not work after I updated to VirtualBox 4.1.12, so maybe at this point, you need to use the VirtualBox GUI.) It takes a while to first bring up the VM, so please be patient. The longest time is in loading the smf service descriptions, but fortunately, that only needs to be done the first time the VM boots.  There is also a delay in just booting the appliance, so give it some time. Be sure to set the NIC rule on only one port and not all ports otherwise there will be a conflict in ports and it won't work. After going through the initial configuration screen, you can connect to it using ssh or your browser: ssh -p 45022 root@<your-host-name> https://<your-host-name>:45215 BTW, for the initial configuration, I only had to set the hostname and password.  The rest of the defaults were set by VirtualBox and seemed to work fine.

  • Reporting on common code smells : A POC

    - by Dave Ballantyne
    Over the past few blog entries, I’ve been looking at parsing TSQL scripts in a variety of ways for a variety of tasks.  In my last entry ‘How to prevent ‘Select *’ : The elegant way’, I looked at parsing SQL to report upon uses of SELECT *.  The obvious question leading on from this is, “Great, what about other code smells ?”  Well, using the language service parser to do that was turning out to be a bit of a hard job,  sure I was getting tokens but no real context.  I wasn't even being told when an end of statement had been reached. One of the other parsing options available from Microsoft is exposed in the assembly ‘Microsoft.SqlServer.TransactSql.ScriptDom’,  this is ,I believe, installed with the client development tools with SQLServer.  It is much more feature rich than the original parser I had used and breaks a TSQL script into intuitive classes for analysis. So, what sort of smells can I now find using it ?  Well, for an opening gambit quite a nice little list. Use of NOLOCK Set of READ UNCOMMITTED Use of SELECT * Insert without column references Explicit datatype conversion on Sargs Cross server selects Non use of two-part naming convention Table and Query hint usage Changes in set options Use of single line comments Use of ordinal column positions in ORDER BY clause Now, lets not argue the point that “It depends” as smells on some of these, but as an academic exercise it is quite interesting.  The code is available from this link :https://www.dropbox.com/s/rfk32sou4fzl2cw/TSQLDomTest.zip  All the usual disclaimers apply to this code, I cannot be held responsible for anything ranging from mild annoyance through to universe destruction due to the use of this code or examples. The zip file contains a powershell script and my test cases.  The assembly used requires .Net 4 to run, which means that you will need powershell 3 ( though im running through PowerGUI and all works ok ) .  The code searches for all .sql files in the folder hierarchy for the workingpath,  you can override this if you want by simply changing the $Folder variable, and processes each in turn for the smells.  Feedback is not great at the moment, all it does is output to an xml file (Smells.xml) the offset position and a description of the smell found. Right now, I am interested in your feedback.  What do you think ?  Is this (or should it be) more than an academic exercise ?  Can tooling such as this be used as some form of code quality measure ?  Does it Work ? Do you have a case listed above which is not being reported ? Do you have a case that you would love to be reported ? Let me know , please mailto: [email protected]. Thanks

  • A brief note for customers running SOA Suite on AIX platforms

    - by christian
    When running Oracle SOA Suite with IBM JVMs on the AIX platform, we have seen performance slowdowns and/or memory leaks. On occasion, we have even encountered some OutOfMemoryError conditions and the concomittant Java coredump. If you are experiencing this issue, the resolution may be to configure -Dsun.reflect.inflationThreshold=0 in your JVM startup parameters. https://www.ibm.com/developerworks/java/library/j-nativememory-aix/ contains a detailed discussion of the IBM AIX JVM memory model, but I will summarize my interpretation and understanding of it in the context of SOA Suite, below. Java ClassLoaders on IBM JVMs are allocated a native memory area into which they are anticipated to map such things as jars loaded from the filesystem. This is an excellent memory optimization, as the file can be loaded into memory once and then shared amongst many JVMs on the same host, allowing for excellent horizontal scalability on AIX hosts. However, Java ClassLoaders are not used exclusively for loading files from disk. A performance optimization by the Oracle Java language developers enables reflectively accessed data to optimize from a JNI call into Java bytecodes which are then amenable to hotspot optimizations, amongst other things. This performance optimization is called inflation, and it is executed by generating a sun.reflect.DelegatingClassLoader instance dynamically to inject the Java bytecode into the virtual machine. It is generally considered an excellent optimization. However, it interacts very negatively with the native memory area allocated by the IBM JVM, effectively locking out memory that could otherwise be used by the Java process. SOA Suite and WebLogic are both very large users of reflection code. They reflectively use many code paths in their operation, generating lots of DelegatingClassLoaders in normal operation. The IBM JVM slowdown and subsequent OutOfMemoryError are as a direct result of the Java memory consumed by the DelegatingClassLoader instances generated by SOA Suite and WebLogic. Java garbage collection runs more frequently to try and keep memory available, until it can no longer do so and throws OutOfMemoryError. The setting sun.reflect.inflationThreshold=0 disables this optimization entirely, never allowing the JVM to generate the optimized reflection code. IBM JVMs are susceptible to this issue primarily because all Java ClassLoaders have this native memory allocation, which is shared with the regular Java heap. Oracle JVMs don't automatically give all ClassLoaders a native memory area, and my understanding is that jar files are never mapped completely from shared memory in the same way as IBM does it. This results in different behaviour characteristics on IBM vs Oracle JVMs.

  • Can't save data for a member in a data form

    - by RahulS
    Implied sharing is an old thing everyone knows the reasons and solutions of that, still little theory about that: With Essbase implied sharing, some members are shared even if you do not explicitly set them as shared. These members are implied shared members. When an implied share relationship is created, each implied member assumes the other member’s value. Essbase assumes (or implies) a shared member relationship in these situations: 1. A parent has only one child 2. A parent has only one child that consolidates to the parent In a Planning form that contains members with an implied sharing relationship, when a value is added for the parent, the child assumes the same value after the form is saved. Likewise, if a value is added for the child, the parent usually assumes the same value after a form is saved.For example, when a calculation script or load rule populates an implied share member, the other implied share member assumes the value of the member populated by the calculation script or load rule. The last value calculated or imported takes precedence. The result is the same whether you refer to the parent or the child as a variable in a calculation script. For more information have a look at: http://docs.oracle.com/cd/E17236_01/epm.1112/hp_admin_11122/ch14s11.html Now the issue which we are going to talk about is We loose data on save even when the parent is dynamic calc and has a single child. A dynamic calc parent to a single child:  If we design the form with following selection: In the data form we will find parent below the member and this is by design whenever you make a selection using commands to select all the member below parent, always children will appear before the parent: Lets try to enter data, Save it Now, try to change the way we selected members Here we go: Now the question again why this behavior: 1. Data from Planning data form passes to Essbase row by row, 2. Because in data form the child member appears before the parent, 3. First, data goes to Essbase for child (SingleStoreChild), 4. Then when Planning passes the data for parent there was #Missing or No data,  5. Over writes the data to #missing. PS: As we know that dynamic calc members are calculated on the fly they are not allocated with any memory in the Essbase, here the parent was dynamic calc and it was pointing to same memory as child in the background, when Planning was passing data to Essbase for second row it has updated the child with missing data.(Little confusing, let me know if you need more explanation) 6. As one of the solutions just change the order of appearance of parent and child. Cheers..!!! Rahul S. https://www.facebook.com/pages/HyperionPlanning/117320818374228

  • Creating a frozen bubble clone

    - by Vaughan Hilts
    This photo illustrates the environment: http://i.imgur.com/V4wbp.png I'll shoot the cannon, it'll bounce off the wall and it's SUPPOSED to stick to the bubble. It does at pretty much every other angle. The problem is always reproduced here, when hit off the wall into those bubbles. It also exists in other cases, but I'm not sure what triggers it. What actually happens: The ball will sometimes set to the wrong cell, and my "dropping" code will detect it as a loner and drop it off the stage. *There are many implementations of "Frozen Bubble" on the web, but I can't for the life of me find a good explanation as to how the algorithm for the "Bubble Sticking" works. * I see this: http://www.wikiflashed.com/wiki/BubbleBobble https://frozenbubblexna.svn.codeplex.com/svn/FrozenBubble/ But I can't figure out the algorithims... could anyone explain possibly the general idea behind getting the balls to stick? Code in question: //Counstruct our bounding rectangle for use var nX = currentBall.x + ballvX * gameTime; var nY = currentBall.y - ballvY * gameTime; var movingRect = new BoundingRectangle(nX, nY, 32, 32); var able = false; //Iterate over the cells and draw our bubbles for (var x = 0; x < 8; x++) { for (var y = 0; y < 12; y++) { //Get the bubble at this layout var bubble = bubbleLayout[x][y]; var rowHeight = 27; //If this slot isn't empty, draw if (bubble != null) { var bx = 0, by = 0; if (y % 2 == 0) { bx = x * 32 + 270; by = y * 32 + 45; } else { bx = x * 32 + 270 + 16; by = y * 32 + 45; } //Check var targetBox = new BoundingRectangle(bx, by, 32, 32); if (targetBox.intersects(movingRect)) { able = true; } } } } cellY = Math.round((currentBall.y - 45) / 32); if (cellY % 2 == 0) cellX = Math.round((currentBall.x - 270) / 32); else cellX = Math.round((currentBall.x - 270 - 16) / 32); Any ideas are very much welcome. Things I've tried: Flooring and Ceiling values Changing the wall bounce to a lower value Slowing down the ball None of these seem to affect it. Is there something in my math I'm not getting?

  • Unable to connect to mail server via IMAP and roundcube

    - by mrhatter
    I am having trouble getting the final parts of my mail server up and working. I followed this tutorial to get everything set up on the mail server side. I have installed roundcube for webmail and configured it but it is saying "error connecting, connection refused" when attempting to connect to it using IMAP. This is thorough the "test imap" section of its installer. Also it is giving me an error message about perissions for it's log and temp folders but that's not as important as acutally getting mail to work. I have also tried connecting to the mail server using thunderbird however it cannot establish a connection either and I know my login information is correct. I know that the databases are working correctly based on the roundcube installer telling me that they have been "successfully initialized". Here are my firewall rules -A INPUT -i lo -j ACCEPT -A INPUT -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT -A INPUT -p tcp -m tcp --dport 22 -j ACCEPT -A INPUT -p tcp -m tcp --dport 25 -j ACCEPT -A INPUT -p tcp -m tcp --dport 80 -j ACCEPT -A INPUT -p tcp -m tcp --dport 443 -j ACCEPT -A INPUT -p tcp -m tcp --dport 465 -j ACCEPT -A INPUT -p tcp -m tcp --dport 487 -j ACCEPT -A OUTPUT -p tcp -m tcp --dport 993 -j ACCEPT -A INPUT -j DROP Which I set up in iptables. I have modified them from what I used in this tutorial I'm not sure what to try next. Any help would be wonderful! I am using Ubuntu 14.04 server, apache 2.4.7, roundcube 1.0.1, and the latest versions of dovecot and postfix. The email databases are contained in mysql. I am running this on a VPS server. UPDATE: I have changed from iptables to using ufw. I have run the following commands to set up a basic firewall with ufw. ufw default deny ufw allow ssh ufw allow http ufw allow https ufw allow imap ufw allow imaps ufw allow smtp I then used telnet to check all of the mail ports. But Port 993 isnt working even though ufw says both 993 and 993/tcp are open. What am I missing?

  • How can I fix broken i915 drivers for Intel GPUs?

    - by Alen Mujezinovic
    I've got troubles getting the i915 drivers to work correctly on my laptop (HP Pavilion DM4 2101ea). Specifically, the laptop screen goes black and stays black after the splash graphic when booting both from USB key and from harddrive. To get anything on to the display after the splash screen I have to boot either with acpi=off nomodeset i915.modeset=0 I'd rather not turn ACPI off because I like my fans spinning and nomodeset is a bit overkill, so for now I'm booting with i915.modeset=0. Unfortunately, this turns off KMS and my current maximum resolution on the laptop screen is fixed to 1024x768 instead of its real capability. When not setting any of the above boot flags and I plug in an external monitor, the external monitor works fine. When booting with the flags, the external monitor works fine too, but can only do 1024x768 and can't do anything else than mirroring the laptop display. I did upgrade the i915 drivers from 2.17 that ship with Precise to 2.19 which are the most recent ones but without luck of getting anything to display. Here's my lspci output: 00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09) 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 00:16.0 Communication controller: Intel Corporation 6 Series/C200 Series Chipset Family MEI Controller #1 (rev 04) 00:1a.0 USB controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #2 (rev 05) 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05) 00:1c.0 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 1 (rev b5) 00:1c.2 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 3 (rev b5) 00:1c.4 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 5 (rev b5) 00:1d.0 USB controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #1 (rev 05) 00:1f.0 ISA bridge: Intel Corporation HM65 Express Chipset Family LPC Controller (rev 05) 00:1f.2 SATA controller: Intel Corporation 6 Series/C200 Series Chipset Family 6 port SATA AHCI Controller (rev 05) 00:1f.3 SMBus: Intel Corporation 6 Series/C200 Series Chipset Family SMBus Controller (rev 05) 01:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01) 02:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd.

  • Is there an API for determining congressional districts?

    - by ardavis
    I'm looking to determine the congressional district based on an address my user is providing. This will avoid having the user to look it up themselves. Does an API of this sort exist? Note Through my attempts to find one, I've only come across these: http://www.govtrack.us/developers/api (not sure how to submit an an address or zip code however) The following resources are available in the API ...Bills and resolutions in the U.S. Congress since 1973 (the 93rd Congress). ...A (bill, person) pair indicating cosponsorship, with join and withdrawn dates. ...Members of Congress and U.S. Presidents since the founding of the nation. ...Terms held in office by Members of Congress and U.S. Presidents. Each term corresponds with an election, meaning each term in the House covers two years (one 'Congress'), as President four years, and in the Senate six years (three 'Congresses'). ...Roll call votes in the U.S. Congress since 1789. How people voted is accessed through the Vote_voter API. ...How people voted on roll call votes in the U.S. Congress since 1789. See the Vote API. Filter on the vote field to get the results of a particular vote... http://www.opencongress.org/api (seems to be a way to find congress information, but not districts) This API provides programmers with structured access to all the data on OpenCongress, everything from official bill info to news and blog coverage to user-generated votes on bills and much more... This API defaults to returning XML. All queries can also return JSON... https://groups.google.com/forum/?fromgroups=#!topic/opendems-discuss/CeKyi_aANaE (similar question, no resolution) I've been looking over Open Dems, and seeing what's exposed at this point and what isn't. I work with Democrats Abroad, and am interested in using stuff from the lab for their sites. I quickly looked over the Precinct API, which does both more and less than what I'd need. An ideal resource would be any way of translating addresses into CD at the very least (getting state district data would be good as well), since that would make it easier for DA's membership to make a difference in races like last month's NY26 race... Update I'm looking at the source for the govtrack.us website and the 'doGeoCode' function may be useful. view-source:http://www.govtrack.us/congress/members If no one has any suggestions, I will try to go off of what they are doing.

  • How can I get my ATI / AMD drivers to work with any kernel above 3.2.0.x?

    - by TorakTu
    How can I get my ATI / AMD drivers to work with any kernel above 3.2.0.x ? WHAT DID WORK Installed original AMD64 version of Ubuntu 12.04 ISO image. Burned DVD and installed which shown kernel 3.2.0-23 to begin with. Got 5.1 surround sound working. Got ATI ( Now its AMD ) video drivers installed for my Radeon HD R6870 Video card from AMD's website. fglrxinfo came up and reported as normal. THE PROBLEM Kernel 3.2.0.x kept locking up so I tried higher kernel versions. But ATI / AMD Drivers do not install on any kernel Above 3.2.0.x WHAT I HAVE TRIED I have gone over this tutorial many times ( https://help.ubuntu.com/community/BinaryDriverHowto/ATI ) and it doesn't work on ANY kernel except 3.2.0.x. The problems I am having here are that the ATI / AMD drivers working for the 12.04 Precise with kernel 3.2.0-23 and 24, But the computer kept locking up. Although all my games would work, the lock ups were random and were constant. So I looked all over the web for 3 days trying to find an answer and the lock up issue was said to just update the kernel. So I did. Have tried many kernels. All of them .. no lock ups. BUT the Restricted AMD drivers from the AMD website will not install. And none of the OpenSource AMD drivers have EVER installed no matter what Kernel or version I tried. EXAMPLE OUTPUT OF 3D TYPE OF ERRORS Javax.media.opengl.GLException: glXGetConfig failed: error code GLX_NO_EXTENSION at com.sun.opengl.impl.x11.X11GLDrawableFactory.glXGetConfig(X11GLDrawableFactory.java:651) at com.sun.opengl.impl.x11.X11GLDrawableFactory.xvi2GLCapabilities(X11GLDrawableFactory.java:350) at com.sun.opengl.impl.x11.X11GLDrawableFactory.chooseGraphicsConfiguration(X11GLDrawableFactory.java:174) at javax.media.opengl.GLCanvas.chooseGraphicsConfiguration(GLCanvas.java:520) at javax.media.opengl.GLCanvas.<init>(GLCanvas.java:131) at haven.HavenPanel.<init>(HavenPanel.java:68) at haven.HavenPanel.<init>(HavenPanel.java:78) at haven.MainFrame.<init>(MainFrame.java:182) at haven.MainFrame.main2(MainFrame.java:306) at haven.MainFrame.access$100(MainFrame.java:34) at haven.MainFrame$7.run(MainFrame.java:360) at java.lang.Thread.run(Thread.java:722) And of course this is what fglrxinfo shows : X Error of failed request: BadRequest (invalid request code or no such operation) Major opcode of failed request: 139 (ATIFGLEXTENSION) Minor opcode of failed request: 66 () Serial number of failed request: 13 Current serial number in output stream: 13 EDIT : I forgot to mention that I DID look at this post over the last few days and it did not help.

  • What is Happening vs. What is Interesting

    - by Geertjan
    Devoxx 2011 was yet another confirmation that all development everywhere is either on the web or on mobile phones. Whether you looked at the conference schedule or attended sessions or talked to speakers at any point at all, it was very clear that no development whatsoever is done anymore on the desktop. In fact, that's something Tim Bray himself told me to my face at the speakers dinner. No new developments of any kind are happening on the desktop. Everyone who is currently on the desktop is working overtime to move all of their applications to the web. They're probably also creating a small subset of their application on an Android tablet, with an even smaller subset on their Android phone. Then you scratch that monolithic surface and find some interesting results. Without naming any names, I asked one of these prominent "ah, forget about the desktop" people at the Devoxx speakers dinner (and I have a witness): "Yes, the desktop is dead, but what about air traffic control, stock trading, oil analysis, risk management applications? In fact, what about any back office application that needs to be usable across all operating systems? Here there is no concern whatsoever with 100% accessibility which is, after all, the only thing that the web has over the desktop, (except when there's a network failure, of course, or when you find yourself in the 3/4 of the world where there's bandwidth problems)? There are 1000's of hidden applications out there that have processing requirements, security requirements, and the requirement that they'll be available even when the network is down or even completely unavailable. Isn't that a valid use case and aren't there 1000's of applications that fall into this so-called niche category? Are you not, in fact, confusing consumer applications, which are increasingly web-based and mobile-based, with high-end corporate applications, which typically need to do massive processing, of one kind or another, for which the web and mobile worlds are completely unsuited?" And you will not believe what the reply to the above question was. (Again, I have a witness to this discussion.) But here it is: "Yes. But those applications are not interesting. I do not want to spend any of my time or work in any way on those applications. They are boring." I'm sad to say that the leaders of the software development community, including those in the Java world, either share the above opinion or are led by it. Because they find something that is not new to be boring, they move on to what is interesting and start talking like the supposedly-boring developments don't even exist. (Kind of like a rapper pretending classical music doesn't exist.) Time and time again I find myself giving Java desktop development courses (at companies, i.e., not hobbyists, or students, but companies, i.e., the places where dollars are earned), where developers say to me: "The course you're giving about creating cross-platform, loosely coupled, and highly cohesive applications is really useful to us. Why do we never find information about this topic at conferences? Why can we never attend a session at a conference where the story about pluggable cross-platform Java is told? Why do we get the impression that we are uncool because we're not on the web and because we're not on a mobile phone, while the reason for that is because we're creating $1000,000 simulation software which has nothing to gain from being on the web or on the mobile phone?" And then I say: "Because nobody knows you exist. Because you're not submitting abstracts to conferences about your very interesting use cases. And because conferences tend to focus on what is new, which tends to be web related (especially HTML 5) or mobile related (especially Android). Because you're not taking the responsibility on yourself to tell the real stories about the real applications being developed all the time and every day. Because you yourself think your work is boring, while in fact it is fascinating. Because desktop developers are working from 9 to 5 on the desktop, in secure environments, such as banks and defense, where you can't spend time, nor have the interest in, blogging your latest tip or trick, as opposed to web developers, who tend to spend a lot of time on the web anyway and are therefore much more inclined to create buzz about the kind of work they're doing." So, next time you look at a conference program and wonder why there's no stories about large desktop development projects in the program, here's the short answer: "No one is going to put those items on the program until you start submitting those kinds of sessions. And until you start blogging. Until you start creating the buzz that the web developers have been creating around their work for the past 10 years or so. And, yes, indeed, programmers get the conference they deserve." And what about Tim Bray? Ask yourself, as Google's lead web technology evangelist, how many desktop developers do you think he talks to and, more generally, what his frame of reference is and what, clearly, he considers to be most interesting.

  • Announcing Key Functional White Papers for SIM and ReIM

    - by Oracle Retail Documentation Team
    Oracle Retail has published two new documents on My Oracle Support (https://support.oracle.com)  that provide partners and retailers with deeper functional information about two products: Oracle Retail Store Inventory Management (SIM) and Oracle Retail Invoice Matching. Oracle Retail Store Inventory Management Item Configuration White Paper (Doc ID 1507221.1) There is functionality within the Store Inventory Management system related to item configuration that spans across multiple concepts that apply to the application as a whole rather than to a specific area. This white paper covers numerous topics around item configuration including: Item Transaction Levels Item Long Description Pack Size Standard Unit of Measure Standard Unit of Measure Conversion Pack Items Simple Pack Conversion Items (Notional Packs) Ranging Items Item Status Non-Sellable Items Type-2 Item Recognition UPC-E Barcodes Non-Inventory Items Consignment and Concession Items Quick Response Codes Oracle Retail Invoice Matching Financial Transactions (Doc ID 1500209.1) This document explains the financial transactions that are posted by Oracle Retail Invoice Matching (ReIM). The scope of the document is limited to ReIM transactions only, and does not explain Retail Merchandising System (RMS), Finance, or Account Receivable transactions. ReIM follows the double-entry accounting standard, which works by recording the debit and credit of each financial transaction belonging to each party involved. Each transaction means a profit to one account (debit) and a loss to another account (credit). Full invoice match processing is completed in ReIM with payment recommendations communicated to Oracle Accounts Payable. ReIM matches merchandise orders and receipts against merchandise invoices, performing automated and manual matching, as well as discrepancy-resolution processing. Matched invoices are posted to interface staging tables specifying the amount and date to pay, vendor, site ID, General Ledger Chart of Accounts (GL CoA) information, and payment terms. Other payables documents, including debit memos, credit memos and credit notes are also interfaced to Accounts Payable through the ReIM staging tables (IM_AP_STAGE_HEAD and IM_AP_STAGE_DETAIL). For information about how ReIM engages in this processing, see the latest Oracle Retail Invoice Matching Operations Guide. Certain ReIM transactions are not interfaced to Oracle Payables, but instead are interfaced to Oracle General Ledger through the IM_FINANCIAL_STAGE table. When analyzing transactions posted through the staging tables, retailers should note the transaction type, Standard/Credit, as well as the sign in the amount field. Technically, a negative sign on a credit transaction changes the transaction to a debit entry, and vice versa. This document is concerned about the financial meaning of the transactions, and will avoid a discussion of negative numbers in T-charts.
