• Highlights From Interact '12 - Healthcare Industry User Group

  - by John Webb

  Last week the Oracle team traveled to Orlando for the 18th annual Healthcare Industry User Group (HIUG) conference, Interact '12.   HIUG has over 3,000 members representing 180 organizations.  While we now know the result on the SCOTUS ruling yesterday, the consensus at the conference last week was summed up well in the welcome note from HIUG President, Chris Ryzewski:    "Regardless of the legal ruling on this administration's  Patient Protection and Affordable Care Act we will undoubtedly be called upon to further reduce costs and be more efficient in every aspect of our business processes."    Well put!   Attendance exceeded previous years with several hundred attendees, over 100 sessions, and a trade show that numbered 40 booths.    Most of the HIUG members use PeopleSoft applications and they tend to be full suite customers who use PeopleSoft broadly from HCM to Financials and Supply Chain. For many customers who have licensed PeopleSoft in the last year, it was their first experience with a very strong and collaborative user group.   I had dinner with a provider who is rolling out PeopleSoft HCM and ERP to a nationwide system of forty hospitals.  A key driver for this organization and others is how to leverage PeopleSoft applications to meet the cost reduction goals mentioned above.   In the area of procurement, the topic of Supplier Contract Management attracted a lot of attention.  Contract pricing and adherence to contracts throughout the procure to pay life cycle are key to meeting cost containment objectives.  Customers were excited to see the new faceted search capabilities and usability of  the upcoming PeopleSoft eProcurement release.     The new Work Center concept was discussed in several areas including the Cost Reconciliation Work Center and the Supply Demand Work Center which enables healthcare specific functions around PAR counts and related replenishment activities.  The latest Feature Pack of HCM 9.1 was demonstrated with the Talent Summary and Manager Dashboard.   Customers were excited to see the major advances in self service available today.    The Grants Special Interest Group focused quite a bit on the usage of PeopleSoft's Project Costing "Funds Distribution" feature, which can be used to manage capital projects funded by multiple agencies and sources.  Along with the latest release of the Mobile Inventory solution that several hospitals have now implemented, a preview of new mobile applications for expenses and approvals drew a lot of attention.   The PeopleSoft focus on assisting these companies in their goals to contain costs and create new efficiencies continues forward.   We look foward to Interact '13!

• cant get ubuntu to work with windows 8

  - by John Mark High

  ive been trying to dual boot Ubuntu with windows 8 but so far I haven't been able too. the laptop im using is a HP Pavilion g6-2240sa pre-installed with windows 8. ive made the bootbale USB with Ubuntu 12.10, it installs but when I restart the computer boot straight into windows, no grub boot options. I can get into Ubuntu once by doing an advanced restart and booting from the Ubuntu partition. I can use Ubuntu fine but once I restart or shutdown, I do the advanced restart again and the Ubuntu partition is now gone and I have to reinstall. i used this tutorial to install Ubuntu, http://www.youtube.com/watch?v=wNCSbTyUzoM After i have to reinstall and still no grub boot menu, i used the boot repair to re-install it. once i rebooted the computer it went straight to windows again and the Ubuntu partition was gone. can i dual boot windows 8 and unbuntu 12.10 with the grub so i can pick what OS to boot into when the computer is starting, and without the partition going AWOL???? Thanks in advance

• New Procurement Report for Transportation Sourcing

  - by John Murphy

  Welcome to our fourth annual transportation procurement benchmark report. American Shipper, in partnership with the Council of Supply Chain Management Professionals (CSCMP) and the Retail Industry Leaders Association (RILA), surveyed roughly 275 transportation buyers and sellers on procurement practices, processes, technologies and results. Some key findings: • Manual, spreadsheet-based procurement processes remain the most prevalent among transportation buyers, with 42 percent of the total • Another 25 percent of respondents use a hybrid platform, which presumably means these buyers are using spreadsheets for at least one mode and/or geography • Only 23 percent of buyers are using a completely systems-based approach of some kind • Shippers were in a holding pattern with regards to investment in procurement systems the past year • Roughly three-quarters of survey respondents report that transportation spend has increased in 2012, although the pace has declined slightly from last year’s increases • Nearly every survey respondent purchases multiple modes of transportation • The number of respondents with plans to address technology to support the procurement process has increased in 2012. About one quarter of respondents who do not have a system report they have a budget for this investment in the next two years.

• The entire content of my Wordpress page has disappeared

  - by John Catterfeld

  I have a blog installed on my site using Wordpress. Last week I upgraded Wordpress from 2.6 to 3.0.4 (I had to do this manually). All went well, or so I thought, but I have just noticed that the content of an existing page has vanished. The page URL still works, but all content has disappeared - doctype, html tags, body tags, everything. Please note, this is specific to pages - posts are still displaying fine. I have since created a brand new page which does not display the content either. Things I have tried include Switching to a freshly installed theme Deactivating all plugins Setting the problem page to draft, and back again Deleting the .htaccess file I suspect it's a database problem and have contacted my hosting company who have said the only thing they can do is restore the DB from a backup, but that I should consider it a last resort. Does anyone have any further ideas what to try?

• What is your most preferred method of site pagination?

  - by John Smith

  There seem to be quite a few implementations of this feature. Some sites like like Stackexchange have it laid out like this: [1][2][3][4][5] ... [954][Next] Other sites like game forums may have something like this: [1][2][3] ... [10] ... [50] ... [500] ... [954][Next] Some sites like webcomics (XKCD comes to mind) have it laid out like this: [Last][Prev][Random][Next][First] Reddit has a very simple pagination with only: [Prev][Next] Sites like Stackexchange and Google also allow you to change how many results you want per page. Personally, I have never used this feature. Is it even worth including or does it just further confuse the design with needless features? Personally, I have only ever seen the need for the webcomic style (without the random). If I need to go to a specific page (which is very, very rare) then I can just edit the address bar. Is it good design to make something more complex for rare occasions where it might make save the user some time? Is having to edit the address bar to navigate the site effectively in some circumstances bad design?

• Run your cpus fast but not hot

  - by John Paul Cook

  Paul Randall recently blogged about the importance of checking to make sure you are getting every bit of speed you should from your cpus. He recommended that people use CPU-Z , a free tool I recommend and have been using for many years. Power saving features in a cpu are great for laptops. Battery life is greatly extended when a processor isn't running to the max all of the time. But this isn't necessarily a good thing for a server. As Paul and others have pointed out, the processor might not get...(read more)

• What ever happened to the Google AJAX Search API

  - by John

  I am looking to query the main Google search however all references including stackoveflow point to the Google AJAX Search API. The odd thing is that it does not seem to exist any more not even a note to say it is depreciated? The old links point to main Google code site. If I look at the list of API's on that site the API it replaced is there Web Search API (Deprecated) which links back to same page but not the Google AJAX Search API. Further Google searching is not being helpful either, many blog posts pointing to the same Google site (http://code.google.com/apis/ajaxsearch/) that has no content and redirects to the same place? Just to prove it did exist I have found it on the way back machine however the last snapshot did not show any special unusual message.

• Creating SparseImages for Pivot

  - by John Conwell

  Learning how to programmatically make collections for Microsoft Live Labs Pivot has been a pretty interesting ride. There are very few examples out there, and the folks at MS Live Labs are often slow on any feedback.  But that is what Reflector is for, right? Well, I was creating these InfoCard images (similar to the Car images in the "New Cars" sample collection that that MS created for Pivot), and wanted to put a Tag Cloud into the info card.  The problem was the size of the tag cloud might vary in order for all the tags to fit into the tag cloud (often times being bigger than the info card itself).  This was because the varying word lengths and calculated font sizes. So, to fix this, I made the tag cloud its own separate image from the info card.  Then, I would create a sparse image out of the two images, where the tag cloud fit into a small section of the info card.  This would allow the user to see the info card, but then zoom into the tag cloud and see all the tags at a normal resolution.  Kind'a cool. But...I couldn't find one code example (not one!) of how to create a sparse image.  There is one page on the SeaDragon site (http://www.seadragon.com/developer/creating-content/deep-zoom-tools/) that gives over the API for creating images and collections, and it sparsely goes over how to create a sparse image, but unless you are familiar with the API already, the documentation doesn't help very much. The key is the Image.ViewportWidth and Image.ViewportOrigin properties of the image that is getting super imposed on the main image.  I'll walk through the code below.  I've setup a couple Point structs to represent the parent and sub image sizes, as well as where on the parent I want to position the sub image.  Next, create the parent image.  This is pretty straight forward.  Then I create the sub image.  Then I calculate several ratios; the height to width ratio of the sub image, the width ratio of the sub image to the parent image, the height ratio of the sub image to the parent image, then the X and Y coordinates on the parent image where I want the sub image to be placed represented as a ratio of the position to the parent image size. After all these ratios have been calculated, I use them to calculate the Image.ViewportWidth and Image.ViewportOrigin values, then pass the image objects into the SparseImageCreator and call Create. The key thing that was really missing from the API documentation page is that when setting up your sub images, everything is expressed in a ratio in relation to the main parent image.  If I had known this, it would have saved me a lot of trial and error time.  And how did I figure this out?  Reflector of course!  There is a tool called Deep Zoom Composer that came from MS Live Labs which can create a sparse image.  I just dug around the tool's code until I found the method that create sparse images.  But seriously...look at the API documentation from the SeaDragon size and look at the code below and tell me if the documentation would have helped you at all.  I don't think so!   public static void WriteDeepZoomSparseImage(string mainImagePath, string subImagePath, string destination) {     Point parentImageSize = new Point(720, 420);     Point subImageSize = new Point(490, 310);     Point subImageLocation = new Point(196, 17);     List<Image> images = new List<Image>();     //create main image     Image mainImage = new Image(mainImagePath);     mainImage.Size = parentImageSize;     images.Add(mainImage);     //create sub image     Image subImage = new Image(subImagePath);     double hwRatio = subImageSize.X/subImageSize.Y;            // height width ratio of the tag cloud     double nodeWidth = subImageSize.X/parentImageSize.X;        // sub image width to parent image width ratio     double nodeHeight = subImageSize.Y / parentImageSize.Y;    // sub image height to parent image height ratio     double nodeX = subImageLocation.X/parentImageSize.X;       //x cordinate position on parent / width of parent     double nodeY = subImageLocation.Y / parentImageSize.Y;     //y cordinate position on parent / height of parent     subImage.ViewportWidth = (nodeWidth < double.Epsilon) ? 1.0 : (1.0 / nodeWidth);     subImage.ViewportOrigin = new Point(         (nodeWidth < double.Epsilon) ? -1.0 : (-nodeX / nodeWidth),         (nodeHeight < double.Epsilon) ? -1.0 : ((-nodeY / nodeHeight) / hwRatio));     images.Add(subImage);     //create sparse image     SparseImageCreator creator = new SparseImageCreator();     creator.Create(images, destination); }

• Dark screen when wake / Unable to control screen brightness

  - by John

  Running Ubuntu 11.04 on Lenovo ThinkPad with an Nvida graphics card. The unit goes to sleep when the lid is shut. (The unit goes to suspend mode (not to disk/hibernate), AC gets turned off, running on battery) Upon lid-open sometimes the screen is almost too dark to read. I'm really not sure of the exact cause, (very low batt??). The only fix is a reboot. The screen brightness buttons have never worked in Ubuntu. I have messed w/ the power management preferences. No change. At one point I messed w/ the gnome settings. No change. I have tried a few cmds: echo 9>/sys/class/backlight/acpi_video0/brightness setpci -s 00:02.0 F4.B=10 xgamma -gamma .75 None of these help. Most have zero effect. I think it is and acpi thing, but that is just a guess. I'm out of idea's, and looking for suggestions. Thanks

• Architecture for subscription based application

  - by John

  This is about the architecture of my application I think. I have a Rails application where companies can administrate all things related to clients. Companies can buy a subscription and their users can access the application online. Hopefully I will get multiple companies subscribing to my appplication/service. Thing is, what should I do with my code and database? Seperate app code base and database per company One app code base but seperate database per company One app code base and one database The decision I am to make involves security (e.g. user from company X should not see any data from company Y) performance (let's suppose it becomes successful, it should have a good performance) and scalability (again, if successful, it should have a good performance but also easy for me to handle all the companies, code changes, etc) For sake of maintainability, I tend to opt for the one code base. For the database I really don't know at this moment. So what do you think is the best option?

• JavaScript Class Patterns &ndash; In CoffeeScript

  - by Liam McLennan

  Recently I wrote about JavaScript class patterns, and in particular, my favourite class pattern that uses closure to provide encapsulation. A class to represent a person, with a name and an age, looks like this: var Person = (function() { // private variables go here var name,age; function constructor(n, a) { name = n; age = a; } constructor.prototype = { toString: function() { return name + " is " + age + " years old."; } }; return constructor; })(); var john = new Person("John Galt", 50); console.log(john.toString()); Today I have been experimenting with coding for node.js in CoffeeScript. One of the first things I wanted to do was to try and implement my class pattern in CoffeeScript and then see how it compared to CoffeeScript’s built-in class keyword. The above Person class, implemented in CoffeeScript, looks like this: # JavaScript style class using closure to provide private methods Person = (() -> [name,age] = [{},{}] constructor = (n, a) -> [name,age] = [n,a] null constructor.prototype = toString: () -> "name is #{name} age is #{age} years old" constructor )() I am satisfied with how this came out, but there are a few nasty bits. To declare the two private variables in javascript is as simple as var name,age; but in CoffeeScript I have to assign a value, hence [name,age] = [{},{}]. The other major issue occurred because of CoffeeScript’s implicit function returns. The last statement in any function is returned, so I had to add null to the end of the constructor to get it to work. The great thing about the technique just presented is that it provides encapsulation ie the name and age variables are not visible outside of the Person class. CoffeeScript classes do not provide encapsulation, but they do provide nicer syntax. The Person class using native CoffeeScript classes is: # CoffeeScript style class using the class keyword class CoffeePerson constructor: (@name, @age) -> toString: () -> "name is #{@name} age is #{@age} years old" felix = new CoffeePerson "Felix Hoenikker", 63 console.log felix.toString() So now I have a trade-off: nice syntax against encapsulation. I think I will experiment with both strategies in my project and see which works out better.

• How can I resolve component types in a way that supports adding new types relatively easily?

  - by John

  I am trying to build an Entity Component System for an interactive application developed using C++ and OpenGL. My question is quite simple. In my GameObject class I have a collection of Components. I can add and retrieve components. class GameObject: public Object { public: GameObject(std::string objectName); ~GameObject(void); Component * AddComponent(std::string name); Component * AddComponent(Component componentType); Component * GetComponent (std::string TypeName); Component * GetComponent (<Component Type Here>); private: std::map<std::string,Component*> m_components; }; I will have a collection of components that inherit from the base Components class. So if I have a meshRenderer component and would like to do the following GameObject * warship = new GameObject("myLovelyWarship"); MeshRenderer * meshRenderer = warship->AddComponent(MeshRenderer); or possibly MeshRenderer * meshRenderer = warship->AddComponent("MeshRenderer"); I could be make a Component Factory like this: class ComponentFactory { public: static Component * CreateComponent(const std::string &compTyp) { if(compTyp == "MeshRenderer") return new MeshRenderer; if(compTyp == "Collider") return new Collider; return NULL; } }; However, I feel like I should not have to keep updating the Component Factory every time I want to create a new custom Component but it is an option. Is there a more proper way to add and retrieve these components? Is standard templates another solution?

• In an Entity-Component-System Engine, How do I deal with groups of dependent entities?

  - by John Daniels

  After going over a few game design patterns, I have settle with Entity-Component-System (ES System) for my game engine. I've reading articles (mainly T=Machine) and review some source code and I think I got enough to get started. There is just one basic idea I am struggling with. How do I deal with groups of entities that are dependent on each other? Let me use an example: Assume I am making a standard overhead shooter (think Jamestown) and I want to construct a "boss entity" with multiple distinct but connected parts. The break down might look like something like this: Ship body: Movement, Rendering Cannon: Position (locked relative to the Ship body), Tracking\Fire at hero, Taking Damage until disabled Core: Position (locked relative to the Ship body), Tracking\Fire at hero, Taking Damage until disabled, Disabling (er...destroying) all other entities in the ship group My goal would be something that would be identified (and manipulated) as a distinct game element without having to rewrite subsystem form the ground up every time I want to build a new aggregate Element. How do I implement this kind of design in ES System? Do I implement some kind of parent-child entity relationship (entities can have children)? This seems to contradict the methodology that Entities are just empty container and makes it feel more OOP. Do I implement them as separate entities, with some kind of connecting Component (BossComponent) and related system (BossSubSystem)? I can't help but think that this will be hard to implement since how components communicate seem to be a big bear trap. Do I implement them as one Entity, with a collection of components (ShipComponent, CannonComponents, CoreComponent)? This one seems to veer way of the ES System intent (components here seem too much like heavy weight entities), but I'm know to this so I figured I would put that out there. Do I implement them as something else I have mentioned? I know that this can be implemented very easily in OOP, but my choosing ES over OOP is one that I will stick with. If I need to break with pure ES theory to implement this design I will (not like I haven't had to compromise pure design before), but I would prefer to do that for performance reason rather than start with bad design. For extra credit, think of the same design but, each of the "boss entities" were actually connected to a larger "BigBoss entity" made of a main body, main core and 3 "Boss Entities". This would let me see a solution for at least 3 dimensions (grandparent-parent-child)...which should be more than enough for me. Links to articles or example code would be appreciated. Thanks for your time.

  I've been to system settings and to User Accounts. My account is the only one on the system and I have previously been able to UnLock the screen so that I could set my account to login without password prompt. That didn't make any effect on the system. I still have to enter a password to log in, but now I can't unlock the User Accounts dialog to make any changes at all. What do I need to reset? note how the unlock box in the upper right hand corner isn't available for selection...

• Is there a modern tutorial for setting up SSL on apache2?

  - by John Baber

  I've been running apache2 for ages on my ubuntu server without SSL. Now that I want to have some directories delivered by SSL, I can't find any straightforward tutorials that were written recently. The best I've found is http://vanemery.com/Linux/Apache/apache-SSL.html but it tells me to put stuff in /etc/httpd/conf I don't want to guess that that should translate to /etc/apache2/conf because guessing based on old tutorials has ruined my web serving before.
