  • Preventing Users From Copying Text From and Pasting It Into TextBoxes

    Many websites that support user accounts require users to enter an email address as part of the registration process. This email address is then used as the primary communication channel with the user. For instance, if the user forgets her password a new one can be generated and emailed to the address on file. But what if, when registering, a user enters an incorrect email address? Perhaps the user meant to enter [email protected], but accidentally transposed the first two letters, entering [email protected]. How can such typos be prevented? The only foolproof way to ensure that the user's entered email address is valid is to send them a validation email upon registering that includes a link that, when visited, activates their account. (This technique is discussed in detail in Examining ASP.NET's Membership, Roles, and Profile - Part 11.) The downside to using a validation email is that it adds one more step to the registration process, which will cause some people to bail out on the registration process. A simpler approach to lessening email entry errors is to have the user enter their email address twice, just like how most registration forms prompt users to enter their password twice. In fact, you may have seen registration pages that do just this. However, when I encounter such a registration page I usually avoid entering the email address twice, but instead enter it once and then copy and paste it from the first textbox into the second. This behavior circumvents the purpose of the two textboxes - any typo entered into the first textbox will be copied into the second. Using a bit of JavaScript it is possible to prevent most users from copying text from one textbox and pasting it into another, thereby requiring the user to type their email address into both textboxes. This article shows how to disable cut and paste between textboxes on a web page using the free jQuery library. Read on to learn more! Read More >

  • Microsoft Build 2012 Day 1 Keynote Summary

    - by Tim Murphy
    So I have finally dried the tears after watching the Keynote for Build 2012.  This wasn’t because it was an emotional presentation, but because for the second year I missed the goodies.  Each on site attendee got a Surface RT, a Lumia 920 and a voucher for 100GB of SkyDrive storage. The event was opened with the announcement that in the three days since the launch of Windows 8 over 4 million upgrades have been sold.  I don’t care who you are that is an impressive stat.  Ballmer then spent a fair amount of time remaking the case for the Windows and Windows Phone platforms similar to what we have heard over the last to launch events. There were some cool, but non-essential demos.  The one that was the most fun was the Perceptive Pixel 82” slate device.  At first glance I wondered why I would ever want such a device, but then Ballmer explained it’s possible use for schools and boardrooms.  The actually made sense. Then things got strange.  Steve started explaining features that developers could leverage.  Usually this type of information is left to the product leads.  He focused on the integration with the Charms features such as Search and Share. Steve “Guggs” Guggenheim showed off an app that would appeal to my kids from Disney called “Agent P” which is base on Phineas and Ferb.  Then he got to the meat of the presentation.  We found out that you could add a tile that can be used to sell ad space.  In the same vein we also found out that you could use Microsoft’s, Paypal’s or any commerce engine of your own creation or choosing. For those who are interested in sports and especially developing sports apps you would have found the small presentation from Michael Bayle of ESPN.  He introduced the ESPN app which has tons of features.  For the developers in the crowd he also mentioned that ESPN has an API available at developer.espn.com. During the launch events we were told apps were coming.  In this presentation we were actually shown a scrolling list of logos and told about a couple of them.  Ballmer mentioned specifically Twitter, SAP and DropBox.  These are impressive names that were just a couple of the list impressive names. Steve Ballmer addressed the question of why you should develop for the Windows 8 platform.  He feels that Microsoft has the best commercial terms for developers, a better way to build apps than other platforms and a variety of form factors.  His key point though was the available volume of customers given the current Windows install base and assuming even a flat growth of the platform.  This he backed with a promise that Microsoft is going to do better at marketing and you won’t be able to avoid the ads that they are bringing out. The last section of the key note was present by Kevin Gallo from the Windows Phone team.  This was the real reason I tuned into the webcast.  He impressed upon those watching that the strength of developing for the Microsoft platform is the common programming model that now exist.  While there are difference between form factor implementations you can leverage code across them. He claimed that 90% of developer requests for Windows Phone 8 had been implemented.  These include: More controls with better performance Better live tiles including lock screen integration Speech support in custom apps Easier submission to the market place App camera integration VOIP and chat support Bluetooth and NFC support Native C++ development Direct 3D development   The quote from Kevin that stood out for me was that “Take your Dramamine and buckle your seatbelt type of games are coming to Windows Phone 8”.  He back this up by displaying a list of game development frameworks and then having Unity come out and do a demo. Ok, almost done … The last two things of note for me were the announcement that the SDK is immediately available at dev.windowsphone.com and that they were reducing the cost of an individual developer account to $8 for the next 8 days. Let the development commence. del.icio.us Tags: Build 2012,Windows 8,Windows Phone 8,Windows Phone

  • fglrx: No matching Device section for instance... found how to fix it?

    - by Lejo
    I have HD 4850 card, Ubuntu 12.10 and installed legacy drivers using makson96 ppa. The issue is, that FGLRX can not detect my device and loads vesa bios. I had the same problem on ubuntu 11.10, 12.04 versions. I want to manually help fglrx find a matching device to load as it shoudld do. It is interesting, why does fglrx search for a device in a PCI:0@1:0:1 Bus? in xorg.cof different bus is indicated: Section "Device" Identifier "aticonfig-Device[0]-0" Driver "fglrx" BusID "PCI:1:0:0" EndSection fglrxinfo display: :0.0 screen: 0 OpenGL vendor string: Advanced Micro Devices, Inc.

  • My father is a doctor. He is insisting on writing a database to store non-critical patient information, with no programming background

    - by Dominic Bou-Samra
    So, my father is currently in the process of "hacking" together a database using FileMaker Pro, a GUI based databasing tool for his small (4 doctor) practice. The database will be used to help ease the burden on reporting from medical machines, streamlining quite a clumsy process. He's got no programming background, and seems to be doing everything in his power to not learn things correctly. He's got duplicate data types, no database-enforced relationships (foreign/primary key constraints) and a dozen other issues. He's doing it all by hand via GUI tool using Youtube videos. My issue is, that whilst I want him to succeed 100%, I don't think it's appropriate for him to be handling these types of decisions. How do I convince him that without some sort of education in these topics, a hacked together solution is a bad idea? He's can be quite stubborn and I think he sees these types of jobs as "childs play" How should I approach this? Is it even that bad an idea - or am I correct in thinking he should hire a proper DBA/developer to handle this so that it doesn't become a maintenance nightmare? NB: I am a developer consultant of 4 years and I've seen my share of painful customer implementations.

  • Forum engine with full LDAP integration [closed]

    - by Andrian Nord
    We are looking for forum engine which may actually maintain user data into LDAP, maybe via mods. Core point is about ability to maintain the data, i.e. all user profile settings, like nickname, password, email, avatar, birthday and others (preferably configurable). One example of good ldap integration, level of which I'm expecting, is drupal's ldap integration, which allows to map any user's attribute into ldap and keeps it in sync with database. Year ago I've done a small research over existing Free&FOSS engines and find out few forum engines with LDAP integration, namely SFM, phpBB and something else. The most maintained solution were provided by phpBB3, which supports LDAP integration out-of-box, but it is unable to sync data with changes in LDAP server made by other software. Actually it wasn't even propagating changes back, I'm not saying about ability to map additional attributes (other than name/password/email). Also, I haven't found any forum with architecture which have proper abstraction over user settings, thus I doubt that this engines (including phpBB) are possible to mod such functionality without introducing dramatic changes into core codebase. More recent research showed that even some commercial software, like IPB is unable to keep it's database synced with LDAP directory and map additional attributes. In other words, all support I've seen so far is simple user creation upon first user's login, which is not good for us, as forum is not primary site and should not maintain it's own users base (to reduce risk of possible collisions). LDAP import is required due to many other services (ftp, email, jabber, drupal site) using same users base. Currently we have forum embedded into Drupal site, but we are unsatisfied with it's features. BTW, we are using Linux and this is not duplicate of this question, as it's author seems to be satisfied with behaviour described above. So, my question is: Are there any (preferably FOSS&free) forum engines that may import, export, keep in sync, or otherwise integrade with LDAP user database (preferably with ability to map additional fields to ldap attributes)?

  • Schizophrenic Ubuntu 12.10-12.04: Atheros 922 PCI WIFI is disabled in Unity but enabled in terminal - How to getit to work?

    - by zewone
    I am trying to get my PCI Wireless Atheros 922 card to work. It is disabled in Unity: both the network utility and the desktop (see screenshot http://www.amisdurailhalanzy.be/Screenshot%20from%202012-10-25%2013:19:54.png) I tried many different advises on many different forums. Installed 12.10 instead of 12.04, enabled all interfaces... etc. I have read about the aht9 driver... The terminal shows no hw or sw lock for the Atheros card, nevertheless, it is still disabled. Nothing worked so far, the card is still disabled. Any help is much appreciated.

  • VirtualBox Clone Root HD / Ubuntu / Network issue

    - by john.graves(at)oracle.com
    When you clone a root Ubuntu disk in VirtualBox, one thing that gets messed up is the network card definition.  This is because Ubuntu (as it should) uses UDEV IDs for the network device.  When you boot your new disk, the network device ID has changed, so it creates a new eth1 device.  Unfortunately, this conflicts with the VirtualBox network setup.  What to do? Boot the box (no network) Edit the /etc/udev/rules.d/70-persistent-net.rules Delete the eth0 line and modify the eth1 line to be eth0 --------- Example OLD ----------- # This file was automatically generated by the /lib/udev/write_net_rules # program, run by the persistent-net-generator.rules rules file. # # You can modify it, as long as you keep each rule on a single # line, and change only the value of the NAME= key. # PCI device 0x8086:0x100e (e1000) <-------------------- Delete these two lines SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="08:00:27:d8:8d:15", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0" # PCI device 0x8086:0x100e (e1000) ---Modify the next line and change eth1 to be eth0 SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="08:00:27:89:84:98", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1" .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } ---------------------------------------- --------- Example NEW ----------- # This file was automatically generated by the /lib/udev/write_net_rules # program, run by the persistent-net-generator.rules rules file. # # You can modify it, as long as you keep each rule on a single # line, and change only the value of the NAME= key. # PCI device 0x8086:0x100e (e1000) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="08:00:27:89:84:98", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0" .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } ----------------------------------------

  • The Evolution of Oracle Direct EMEA by John McGann

    - by user769227
    John is expanding his Dublin based team and is currently recruiting a Director with marketing and sales leadership experience: http://bit.ly/O8PyDF Should you wish to apply, please send your CV to [email protected] Hi, my name is John McGann and I am part of the Oracle Direct management team, based in Dublin.   Today I’m writing from the Oracle London City office, right in the heart of the financial district and up to very recently at the centre of a fantastic Olympic Games. The Olympics saw individuals and teams from across the globe competing to decide who is Citius, Altius, Fortius - “Faster, Higher, Stronger" There are lots of obvious parallels between the competitive world of the Olympics and the Business environments that many of us operate in, but there are also some interesting differences – especially in my area of responsibility within Oracle. We are of course constantly striving to be the best - the best solution on offer for our clients, bringing simplicity to their management, consumption and application of information technology, and the best provider when compared with our many niche competitors.   In Oracle and especially in Oracle Direct, a key aspect of how we achieve this is what sets us apart from the Olympians.  We have long ago eliminated geographic boundaries as a limitation to what we can achieve. We assemble the strongest individuals across multiple countries and bring them together in teams focussed on a single goal. One such team is the Oracle Direct Sales Programs team. In case you don’t know, Oracle Direct EMEA (Europe Middle East and Africa) is the inside sales division in Oracle and it is where I started my Oracle career.  I remember that my first role involved putting direct mail in envelopes.... things have moved on a bit since then – for me, for Oracle Direct and in how we interact with our customers. Today, the team of over 1000 people is located in the different Oracle Direct offices around Europe – the main ones are Malaga, Berlin, Prague and Dubai plus the headquarters in Dublin. We work in over 20 languages and are in constant contact with current and future Oracle customers, using the latest internet and telephone technologies to effectively communicate and collaborate with each other, our customers and prospects. One of my areas of responsibility within Oracle Direct is the Sales Programs team. This team of 25 people manages the planning and execution of demand generation, leading the process of finding new and incremental revenue within Oracle Direct. The Sales Programs Managers or ‘SPMs’ are embedded within each of the Oracle Direct sales teams, focussed on distinct geographies or product groups. The SPMs are virtual members of the regional sales management teams, and work closely with the sales and marketing teams to define and deliver demand generation activities. The customer contact elements of these activities are executed via the Oracle Direct Sales and Business Development/Lead Generation teams, to deliver the pipeline required to meet our revenue goals. Activities can range from pan-EMEA joint sales and marketing campaigns, to very localised niche campaigns. The campaigns might focus on particular segments of our existing customers, introducing elements of our evolving solution portfolio which customers may not be familiar with. The Sales Programs team also manages ‘Nurture’ activities to ensure that we develop potential business opportunities with contacts and organisations that do not have immediate requirements. Looking ahead, it is really important that we continue to evolve our ability to add value to our clients and reduce the physical limitations of our distance from them through the innovative application of technology. This enables us to enhance the customer buying experience and to enable the Inside Sales teams to manage ever more complex sales cycles from start to finish.  One of my expectations of my team is to actively drive innovation in how we leverage data to better understand our customers, and exploit emerging technologies to better communicate with them.   With the rate of innovation and acquisition within Oracle, we need to ensure that existing and potential customers are aware of all we have to offer that relates to their business goals.   We need to achieve this via a coherent communication and sales strategy to effectively target the right people using the most effective medium. This is another area where the Sales Programs team plays a key role.

  • Benchmarking ORM associations

    - by barerd
    I am trying to benchmark two cases of self referential many to many as described in datamapper associations. Both cases consist of an Item clss, which may require many other items. In both cases, I required the ruby benchmark library and source file, created two items and benchmarked require/unrequie functions as below: Benchmark.bmbm do |x| x.report("require:") { item_1.require_item item_2, 10 } x.report("unrequire:") { item_1.unrequire_item item_2 } end To be clear, both functions are datamapper add/modify functions like: componentMaps.create :component_id => item.id, :quantity => quantity componentMaps.all(:component_id => item.id).destroy! and links_to_components.create :component_id => item.id, :quantity => quantity links_to_components.all(:component_id => item.id).destroy! The results are variable and in the range of 0.018001 to 0.022001 for require function in both cases, and 0.006 to 0.01 for unrequire function in both cases. This made me suspicious about the correctness of my test method. Edit I went ahead and compared a "get by primary key case" to a "finding first matching record case" by: (1..10000).each do |i| Item.create :name => "item_#{i}" end Benchmark.bmbm do |x| x.report("Get") { item = Item.get 9712 } x.report("First") { item = Item.first :name => "item_9712" } end where the results were very different like 0 sec compared to 0.0312, as expected. This suggests that the benchmarking works. I wonder whether I benchmarked the two types of associations correctly, and whether a difference between 0.018 and 0.022 sec significant?

  • RPi and Java Embedded GPIO: Big Data and Java Technology

    - by hinkmond
    Java Embedded and Big Data go hand-in-hand, especially as demonstrated by prototyping on a Raspberry Pi to show how well the Java Embedded platform can perform on a small embedded device which then becomes the proof-of-concept for industrial controllers, medical equipment, networking gear or any type of sensor-connected device generating large amounts of data. The key is a fast and reliable way to access that data using Java technology. In the previous blog posts you've seen the integration of a static electricity sensor and the Raspberry Pi through the GPIO port, then accessing that data through Java Embedded code. It's important to point out how this works and why it works well with Java code. First, the version of Linux (Debian Wheezy/Raspian) that is found on the RPi has a very convenient way to access the GPIO ports through the use of Linux OS managed file handles. This is key in avoiding terrible and complex coding using register manipulation in C code, or having to program in a less elegant and clumsy procedural scripting language such as python. Instead, using Java Embedded, allows a fast way to access those GPIO ports through those same Linux file handles. Java already has a very easy to program way to access file handles with a high degree of performance that matches direct access of those file handles with the Linux OS. Using the Java API java.io.FileWriter lets us open the same file handles that the Linux OS has for accessing the GPIO ports. Then, by first resetting the ports using the unexport and export file handles, we can initialize them for easy use in a Java app. // Open file handles to GPIO port unexport and export controls FileWriter unexportFile = new FileWriter("/sys/class/gpio/unexport"); FileWriter exportFile = new FileWriter("/sys/class/gpio/export"); ... // Reset the port unexportFile.write(gpioChannel); unexportFile.flush(); // Set the port for use exportFile.write(gpioChannel); exportFile.flush(); Then, another set of file handles can be used by the Java app to control the direction of the GPIO port by writing either "in" or "out" to the direction file handle. // Open file handle to input/output direction control of port FileWriter directionFile = new FileWriter("/sys/class/gpio/gpio" + gpioChannel + "/direction"); // Set port for input directionFile.write("in"); // Or, use "out" for output directionFile.flush(); And, finally, a RandomAccessFile handle can be used with a high degree of performance on par with native C code (only milliseconds to read in data and write out data) with low overhead (unlike python) to manipulate the data going in and out on the GPIO port, while the object-oriented nature of Java programming allows for an easy way to construct complex analytic software around that data access functionality to the external world. RandomAccessFile[] raf = new RandomAccessFile[GpioChannels.length]; ... // Reset file seek pointer to read latest value of GPIO port raf[channum].seek(0); raf[channum].read(inBytes); inLine = new String(inBytes); It's Big Data from sensors and industrial/medical/networking equipment meeting complex analytical software on a small constraint device (like a Linux/ARM RPi) where Java Embedded allows you to shine as an Embedded Device Software Designer.

  • How will my Electronic Engineering degree be received in the Canadian Game Development market? [closed]

    - by Harikawashi
    I have a Electronic Engineering with Computer Science Degree from a reputable South African university. The EE with CS degree is basically Electronic Engineering, with some of the high voltage subjects thrown out and replaced with computer science subjects - mostly quite theoretical, but not in too much depth. I went on to earn a Masters Degree in Digital Signal Processing, focussing on Speech Recognition in Educational Applications. I have always loved programming - I taught myself QBASIC when I was in primary school, I learned Java at school, did some low level C at University, and taught myself C# and Python while doing my post graduate degree. C# is currently my strong suit, I think I am pretty capable with it. I have two years work experience in Namibia - working as a consulting electrical engineer (no software content whatsoever) and also developing C# desktop applications for the company I work for. I would like to move to Canada next year and work in the Game Development Industry as programmer or software engineer. My interests in particular are towards the more mathematical applications, like game and physics engines, or statistical disciplines like artificial intelligence. However, these are passions - not areas in which I have any work experience. So the question: How well will my BEngEE&CS and MScEng be received in the game industry? Seeing as it's not a pure software degree and I have no official software development work experience?

  • OOP oriented PHP app source code samples and advice

    - by abel
    The day I have been dreading has arrived. I never felt OOP or good software design was important(I knew they were important, but I thought I could manage without them.). However having read otherwise almost everywhere on the interwebs, I started dreading the day when my client would ask me for new features in an existing app. The day has come and the pain is unbearable! I have never coded my PHP websites "properly"(PHP is my primary language and the bulk of my work. I am learning Python (using web2py)) I take care that the website doesn't fall apart in a daily use scenario. I code pages like I was creating a list of static html files with bits of "magic code" in each of them(this bugs me a lot). How do I make the whole app more or less a single object? For eg. How do I design the object model for an invoicing app? I use a lot of functions for doing any particular thing in the same fashion throughout the app(for eg. validation, generating ids, calculating taxes etc.). I know the basics of OOP in general. Can anyone point me to source code samples of functional apps written in php? Or can someone provide pointers so I can recode my existing apps in a more modular way.

  • Booting the liveCD/USB in EFI mode fails on Samsung Tablet XE700T1A

    - by F.L.
    My tablet is Samsung Series 7 Slate (XE700T1A-A02FR (French Language)). It operates an Intel Sandy Bridge architecture. The main issue about this tablet is that it ships with an installed Windows 7 in (U)EFI mode (GPT partition table, etc.), so I'd like to get an EFI dual boot with Ubuntu. But it seems I can't boot on the liveCD in EFI mode. It starts loading (up to initrd), but I then get a blank (black) screen. I've tried the nomodeset kernel option (as well as removing quiet and splash) with no luck. [2012-09-27] I have used the Ubuntu 12.04.1 Desktop ISO (I have read somewhere that it is the only one that can boot in EFI mode). I'd say this has something to do with UEFI since the LiveCD boots in bios mode but not in efi mode. Besides, I am not sure my boot info will help, since I can't boot the LiveCD in EFI mode. As a result I can't install ubuntu in EFI mode. So it would be the boot info from the liveCD boot in bios mode. This happens on a ubuntu-12.04.1-desktop-amd64 iso used on a LiveUSB. Live USB was created by dd'ing the iso onto the full disk device (i.e. /dev/sdx no number) of the Flash drive. I have also tried copying the LiveCD files on a primary GPT partition, but with no luck, I just get the grub shell, no menu, no install option. [2012-09-28] I tried today a flash drive created with Ubuntu's Startup Disk Creator and the alternate 12.04.1 64 bit ISO. I get a grub menu in text mode (which meens it did start in efi mode) with install options / test options. But when I start any of these, I simply get a black screen (no cursor, neither mouse nor text-mode cursor). I tried removing the 'quiet' option and adding nomodeset and acpi=off, but it didn't do any good. So this is the same result as for the LiveCD. [2012-10-01] I have tried with a version of the secure remix version via usb-creator-gtk. The boot on the USB key has the same symptoms. Boot in EFI mode is impossible (I have menu but whatever entry I choose, I get the blank screen problem). The boot in BIOS mode works, I did the install. Then I used boot-repair to try installing grub-efi and get a system that would boot in efi mode. But I can't boot this system, because the EFI firmware doesn't seem to detect that sda contains a valid efi partition. Here is the resulting boot-info Boot info 1253554 [2012-10-01] Today, I have reinstalled the pre-shipped version of windows 7, and then installed ubuntu from a secure-remix iso dumped on USB flash drive vie usb-creator-gtk booted in BIOS mode. When install ended, I said "continue testing" then I used boot-repair to try get the bootloader installed. Now, when I boot the tablet, I get the grub menu, it can chainload windows 7 flawlessly. But when I try to start one of the ubuntu options I get the same old blank screen. Here is the new boot-info: Boot info 1253927 [2012-10-01] I tried installing the 3.3 kernel by chrooting a live usb boot (secure remix again) into the installed system. Same symptoms. I feel the key to this is that the device's efi firmware (which is EFI v2.0) would expose the graphics hardware in a way that prevents the kernel to initialize it, and thus prevents it from booting (the kernel stops all drive access just after the screen turns kind of very dark purple). Here is some info on the UEFI firmware as given by rEFInd: EFI revision: 2.00 Platform: x86_64 (64 bit) Firmware: American Megatrends 4.635 Screen Output: Graphics Output (UEFI), 800x600 [2012-10-08] This week end I tried loading the kernel with elilo. Eventhough I didn't have more luck on booting the kernel, elilo gives more info when loading the kernel. I think the next step is trying to load a kernel with EFI stub directly.

  • TCO Comparison: Oracle Exadata vs IBM P-Series

    - by Javier Puerta
    Cost Comparison for Business Decision-makersOracle Exadata Database Machine vs. IBM Power SystemsHow to Weigh a Purchase DecisionOctober 2012 Download full report here In this research-based  white paper conducted at the request of Oracle, The FactPoint Group compares the cost of ownership of the Oracle Exadata engineered system to a traditional build-your-own (BYO) solution, in this case an IBM Power 770 (P770) with SAN storage.  The IBM P770 was chosen given it is IBM’s current most popular model, based on FactPoint primary and secondary research and IBM claims, and because at least one of the interviewed customers had specifically migrated from a P770 to Exadata, affording us a more specific data point for comparison. This research found that Oracle Exadata: Can be deployed more quickly and easily requiring 59% fewer man-hours than a traditional IBM Power Systems solution. Delivers dramatically higher performance typically up to 12X improvement, as described by customers, over their prior solution.  Requires 40% fewer systems administrator hours to maintain and operate annually, including quicker support calls because of less finger-pointing and faster service with a single vendor.  Will become even easier to operate over time as users become more proficient and organize around the benefits of integrated infrastructure. Supplies a highly available, highly scalable and robust solution that results in reserve capacity that make Exadata easier for IT to operate because IT administrators can manage proactively, not reactively.  Overall, Exadata operations and maintenance keep IT administrators from “living on the edge.”  And it’s pre-engineered for long-term growth. Finally, compared to IBM Power Systems hardware, Exadata is a bargain from a total cost of ownership perspective:  Over three years, the IBM hardware running Oracle Database cost 31% more in TCO than Exadata.

  • Information on upgrading Kinect Applications to MS SDK Beta 2.

    - by mbcrump
    Introduction Microsoft recently released the Kinect for Windows SDK Beta 2. It contains many enhancements and fixes that can be found here. The only problem with it is that a lot of current demo applications no longer function properly. Today, I’m going to walk you through a typical scenario of upgrading a Kinect application built with Beta 1 to Beta 2. Note: This tutorial covers WPF, but you can use the same techniques for WinForms. 1) Fix the references Let’s start with a fairly popular Kinect demo called Kinect User Interface Demo. This project uses the beta 1 version of Microsoft.Research.Kinect.dll and version 1.0.0.0 of Coding4Fun’s Kinect library. After you download the source code and extract the zip you will see the following references in Visual Studio 2010: Pay attention to the following references as these are the .dlls that you will have to update: Coding4Fun.Kinect.Wpf Microsoft.Research.Kinect If you click on Coding4Fun.Kinect.Wpf file you will see the following version information (v1.0.0.0): This needs to be upgraded to the Coding4Fun Kinect library built against Beta 2. So head over to http://c4fkinect.codeplex.com/ and hit download and you will have the following files. Go ahead and hit the delete key on your keyboard to remove the Coding4Fun.Kinect.Wpf.dll file from your project. Select “Add Reference” and navigate out to the folder where you extracted the files and select Coding4Fun.Kinect.Wpf.dll. If you click on the Coding4Fun.Kinect.Wpf.dll file and check properties it should be listed at 1.1.0.0: Fix Microsoft.Research.Kinect.dll The official SDK Beta 2 released a new .dll that you will need to reference in your application. Go ahead and select Microsoft.Research.Kinect.dll in your application and hit the Delete key on your keyboard. Go ahead and select Add Reference again and select Microsoft.Research.Kinect.dll from the .NET tab. Double check and make sure the version number is 1.0.0.45 as shown below. References fixed – Runtime needs to be updated. So we have fixed the references in a typical Kinect application that uses Microsoft’s SDK and C4F Kinect libraries. Now, we will need to update the runtime. All Beta 1 Kinect applications will instantiate the Runtime with the following code: Can you see that it is now marked with [Depreciated]? That means we need to update it before Microsoft decides to remove it from future versions of the SDK. We can fix this very easily by replacing this code: readonly Runtime _runtime = new Runtime(); with Microsoft.Research.Kinect.Nui.Runtime _nui; and adding similar code to our Loaded event as shown below public MainWindow() { InitializeComponent(); Loaded += new RoutedEventHandler(MainWindow_Loaded); } void MainWindow_Loaded(object sender, RoutedEventArgs e) { if (Runtime.Kinects.Count == 0) { txtInfo.Text = "Missing Kinect"; } else { _nui = Runtime.Kinects[0]; _nui.Initialize(RuntimeOptions.UseColor); // Video Frame Ready Event can happen now!!! //_nui.VideoFrameReady += new EventHandler<ImageFrameReadyEventArgs>(_nui_VideoFrameReady); _nui.VideoStream.Open(ImageStreamType.Video, 2, ImageResolution.Resolution640x480, ImageType.Color); } } In this sample, I am testing to see if a Kinect is detected and if it is then I initialize the runtime with my first Kinect by using the Runtime.Kinects[0]. You can also specify other Kinect devices here. The rest of the code is standard code that you simply modify however you wish (ie Skeletal, Depth, etc) depending on what type of video feed you want. Conclusion As you can see it really wasn’t that painful to upgrade your project to Beta 2. I would recommend that you go ahead and upgrade to Beta 2 as future versions of the SDK will use these methods.  Thanks for reading. Subscribe to my feed

  • Where do I start in regards to making a Gnome/Unity Form Application

    - by JMK
    Ok so I am familiar with developing Form and Console applications on Windows using Visual Studio .Net with C#, but where do I start when it comes to Linux distro's like Ubuntu, is there an equivalent? How would one go about matching what they can do in a Windows environment with .Net and C# in a Linux environment without .Net coding in something like Java or C/C++? I am aware of Eclipse, does eclipse have a form designer or do you have to code the design of any Gnome/Unity forms manually? Can I use eclipse to write the Linux equivalent of a console application, that you just double click on to run? I also know about Mono, but the idea is that I want to learn how to develop software without using anything in the Microsoft stack and am not sure where to start. What is the standard language/framework used to develop these types of applications on Linux? As I become more proficient with Visual Studio, C# and .Net, it has struck me that without these Microsoft tools, I am nothing. I am only capable of developing for the Microsoft OS and this scares me. This isn't some anti Microsoft thing, Microsoft makes some incredible Software/Hardware/Operating Systems/IDE's, but it is generally a bad idea to put all of your eggs in one basket so if I want to learn how to develop Terminal and Gnome/Unity form applications where in the world do I start? I have used Linux on and off for years, but Windows has been my primary OS. However I have watched Linux get better and better and as much as I love Windows 7, I am dubious about Windows 8 (I for one will sorely miss my start menu)! Obviously MS aren't going anywhere anytime soon and I could spend the the next couple of decades developing for .Net without any issues but just because you can get away with something doesn't always mean it's a good idea. Thanks

  • The Healthy Tension That Mobility Creates

    - by Kathryn Perry
    A guest post by Hernan Capdevila, Vice President, Oracle Fusion Apps In my previous post, I talked about the value of the mobile revolution on businesses and workers. Now let me put on a different hat and view the world from the IT department and the IT leader’s viewpoint. The IT leader has different concerns – around privacy, potential liability of information leakage, and intellectual property protection. These concerns and the leader’s goals create a healthy tension with the users. For example, effective device management becomes a must have for the IT leader, especially if you look at the Android ecosystem as an example. There are benefits to the Android strategy, but there are also drawbacks, such as uniformity – in device management, in operating systems, and in the application taxonomy and capabilities. Whereas, if you compare Android to iOS, Apple's operating system, iOS is more unified, more streamlined, and easier to manage. In either case, this is where mobile device management in the cloud makes good sense. I don't think IT departments should be hosting device management and managing that complexity. It should be a cloud service and I predict it's going to be key for our customers. A New Focus for IT Departments So where does that leave the IT departments? I think their futures are in governance, which is a more strategic play than a tactical one. Device management is tactical and it's the “now” topic. But the mobile phenomenon, if you will, is going to drive significant change in terms of how IT plans, hosts, and deploys enterprise applications. For example, opening up enterprise applications for mobile users presents some challenges unless you deploy more complicated network topologies, such as virtual private networks and threat protection technology. If you really want employees to be mobile you need to remove those kinds of barriers. But I don’t think IT departments want to wrestle with exposing their private enterprise data centers and being responsible for hosted business applications – applications in a sense that they’re making vulnerable to the public world. This opens up a significant need and a significant driver for cloud applications. However, it's not just about taking away the complexity – it's also about taking away the responsibility. Why should every business have to carry the responsibility and figure out all the nuts and bolts of how to protect themselves in this public, mobile world? When you use apps in the cloud, either your vendor or your hosting partner should have figured all that out. They need to assure the business that they are adhering to all sorts of security and compliance regulations so users can be connected and have access to information anywhere anytime. More Ideas and Better Service What’s more interesting is the world of possibilities that the connected, cloud-based world enables. I believe that the one-size-fits-all, uber-best practices, lowest-common denominator-like capabilities will go away. IT will now be able to solve very specific business challenges for the different corporate functions it serves. In this new world, IT will play a key role in enabling different organizations within a company to be best in class and delivering greater value to the line of business managers. IT will actually help to differentiate. Net result is a more agile workforce and business because each department is getting work done its own way.

  • Get to Know a Candidate (6 of 25): Jill Stein&ndash;Green Party

    - by Brian Lanham
    DISCLAIMER: This is not a post about “Romney” or “Obama”. This is not a post for whom I am voting. Information sourced for Wikipedia. Stein is a physician with degrees from Harvard College and Harvard Medical School.  She serves on the boards of Greater Boston Physicians for Social Responsibility and MassVoters for Fair Elections, and has been active with the Massachusetts Coalition for Healthy Communities Jill Stein advocates a "Green New Deal" in which renewable energy jobs would be created to address climate change and environmental issues with the objective of employing "every American willing and able to work". Citing the research of Dr. Phillip Harvey, Professor of Law & Economics at Rutgers University, as evidence of the successful economic effects of the 1930s' New Deal projects, Stein would fund the plan with a 30% reduction in the U.S. military budget, returning US troops home, and increasing taxes on areas such as capital gains, offshore tax havens and multimillion dollar real estate. Stein plans on impacting what she sees as a growing convergence of environmental crises in water, soil, fisheries and forests, through the creation of sustainable infrastructure based in clean renewable energy generation and sustainable communities principles such as increasing intra-city mass transit and inter-city railroads, creating 'complete streets' that safely encourage bike and pedestrian traffic and regional food systems based on sustainable organic agriculture The Green Party of the United States was founded in 1991 as a voluntary association of state green parties. With its founding, the Green Party of the United States became the primary national Green organization in the United States, eclipsing the Greens/Green Party USA, which emphasized non-electoral movement building. The Green Party of the United States of America emphasizes environmentalism, non-hierarchical participatory democracy, social justice, respect for diversity, peace and nonviolence. Their "Ten Key Values," which are described as non-authoritative guiding principles, are as follows: Grassroots democracy Social justice and equal opportunity Ecological wisdom Nonviolence Decentralization Community-based economics Feminism and gender equality Respect for diversity Personal and global responsibility Future focus and sustainability The Green Party does not accept donations from corporations. Thus, the party's platforms and rhetoric critique any corporate influence and control over government, media, and American society at large. Stein has access to 403 electoral votes and is a write-in candidate in GA, IN, and MS Learn more about Jill Stein and Green Party on Wikipedia.

  • Fixed-Function vs Shaders: Which for beginner?

    - by Rob Hays
    I'm currently going to college for computer science. Although I do plan on utilizing an existing engine at some point to create a small game, my aim right now is towards learning the fundamentals: namely, 3D programming. I've already done some research regarding the choice between DirectX and OpenGL, and the general sentiment that came out of that was that whether you choose OpenGL or DirectX as your training-wheels platform, a lot of the knowledge is transferrable to the other platform. Therefore, since OpenGL is supported by more systems (probably a silly reason to choose what to learn), I decided that I'm going to learn OpenGL first. After I made this decision to learn OpenGL, I did some more research and found out about a dichotomy that I was somewhere unaware of all this time: fixed-function OpenGL vs. modern programmable shader-based OpenGL. At first, I thought it was an obvious choice that I should choose to learn shader-based OpenGL since that's what's most commonly used in the industry today. However, I then stumbled upon the very popular Learning Modern 3D Graphics Programming by Jason L. McKesson, located here: http://www.arcsynthesis.org/gltut/ I read through the introductory bits, and in the "About This Book" section, the author states: "First, much of what is learned with this approach must be inevitably abandoned when the user encounters a graphics problem that must be solved with programmability. Programmability wipes out almost all of the fixed function pipeline, so the knowledge does not easily transfer." yet at the same time also makes the case that fixed-functionality provides an easier, more immediate learning curve for beginners by stating: "It is generally considered easiest to teach neophyte graphics programmers using the fixed function pipeline." Naturally, you can see why I might be conflicted about which paradigm to learn: Do I spend a lot of time learning (and then later unlearning) the ways of fixed-functionality, or do I choose to start out with shaders? My primary concern is that modern programmable shaders somehow require the programmer to already understand the fixed-function pipeline, but I doubt that's the case. TL;DR == As an aspiring game graphics programmer, is it in my best interest to learn 3D programming through fixed-functionality or modern shader-based programming?

  • Use Your Android Phone to Comparison Shop: 4 Scanner Apps Reviewed

    - by Jason Fitzpatrick
    A smart phone in your pocket is great for on the go news, web browsing, and—of course—mobile gaming. It’s also fantastic for comparison shopping. Today we take a look at four Android scanners and price comparison engines. It’s quite a neat time to be a consumer. Historically if you wanted to do serious price comparisons you had to haul yourself around town, gather flyers from the newspapers, and otherwise invest way too much energy into potential savings that might not even break into double digits. Now you can comparison shop with an ease that borders on magic: by simply pulling out your smart phone and scanning the barcode or typing in the name of the item you wish to compare. Today we’re taking a look at some of the more popular and powerful barcode scanners and price comparison engines available for the Android platform. Before we get to that, a word on our methodology. To test the barcode scanners and the resulting search results we wandered around and rounded up some relatively random items from around the How-To Geek offices. This included a children’s graphic novel, a Wii game, a board game, a pack of razors, a box of tea, and a bottle of nail polish. It’s a decent spread of consumer items that covers several genres. For each application we scanned all the items, looked for the best price at the time, and noted any other relevant benefits of using one scanner over another. It’s worth noting that our primary focus was on the speed and ease of use. You may find that certain scanners have specific features that best suit your needs. What we focused on was how fast you could scan, compare prices, and purchase items if you desired. Since all the scanners are free-as-in-beer, feel free to download them all and run your own tests to confirm our conclusions.

  • Data that has been deleted in P6, how is it updated in Analytics

    - by Jeffrey McDaniel
    In P6 Reporting Database 2.0 the ETL process looked to the refrdel table in the P6 PMDB to determine which projects were deleted. The refrdel table could not be cleared out between ETL runs or those deletes would be lost. After the ETL process is run the refrdel can be cleared out. It is important to keep any purging of the refrdel in a consistent cycle so the ETL process can pick up these deletes and process them accordingly.  In P6 Reporting Database 2.2 and higher the Extended Schema is used as the data source. In the Extended Schema, deleted data is filtered out by the views. The Extended Schema services will handle any interaction with the refrdel table, this concern with timing refrdel cleanup and ETL runs is not applicable as of this release. In the Extended Schema tables (ex. TaskX) there can still be deleted data present. The Extended Schema views join on the primary PMDB tables (ex. Task) and filter out any deleted data.  Any data that was deleted that remains in the Extended Schema tables can be cleaned out at a designated time by running the clean up procedure as documented in the P6 Extended Schema white paper. This can be run occasionally but is not necessary to run often unless large amounts of data has been deleted.

  • Worker roles in Windows Azure to host a multiplayer server

    I've been doing research on where to host a simple multi-player backend for a simple game I'm developing. So as a first choice I downloaded the Windows Azure SDK, which provides a nice and simple emulator environment where you can test out your application before uploading. I also download the Azure Social Game Toolkit (Visit), and followed as far as my understanding can take me. So, down to the main question. Is there anybody with experience developing Azure applications. I'm developing a Action RPG game, in a similar vein to Diablo III. I was thinking of putting up Matchmaking, Friends Lists, etc. Is there another way to connect to Azure services via something like UDP or TCP for sending packets or does everything have to go through HTTP requests? Is it even possible to use HTTP request/response for something like this? All game commands will be simple. Because the game server and the clients will be kept in-sync and will have deterministic actions, I'm just going to send actions like "Use Primary Skill" and "Use Secondary Skill". Any hints, ideas, light bulbs or a smack-in-the-face presentation will be much appreciated.

  • A case for not installing your own software

    - by James Gentsch
    This week I watched some of the Oracle Open World presentations (from the comfort of my Oracle office) and happened on some of Larry Ellison’s comments about cloud computing and engineered systems.  Larry said he sees the move to these as analogous to the moves made by the original adopters of electricity.  The argument goes that the first consumers of electricity had to set up their own power plant.  Then, as the market and infrastructure for electricity matured, power consumers moved from using their own personal power plant to purchasing power from another entity that was focused on power production as their primary product. In the end this was a cheaper and more reliable solution. Now, there are lots of compelling reasons to be looking very seriously at cloud computing and engineered systems for enterprise application deployment.  However, speaking as a software developer of enterprise applications, the part of this that I really love (besides Larry’s early electricity adopter analogy) is that as a mode of application deployment it provides me and my customers a consistent environment in which the applications I am providing will be run.  This cuts way down on the environmental surprises that consistently lead to the hated “well, it works here” situation with the support desk. And just to be clear, I think I hate this situation more than my clients, who I think are happy that at least it is working somewhere.  I hate this because when a problem happens, and let’s face it customers are not wasting their time calling in easy problems, we are seriously disabled when we cannot reproduce the issue which is triggered by something unforeseen in the environment where the application is running.  This situation is incredibly frustrating and an all too often occurrence. I look selfishly forward to cloud computing and engineered systems dramatically reducing the occurrence of problems triggered by unforeseen environmental situations in the software I am responsible for.  I think this is an evolutionary game changer that will be a huge benefit to the reliability and consistent performance of the software for my customers, and may make “well, it works here” a well forgotten phase for future software developers. It may even impact the stress squeeze toy industry.  Well, maybe at least for my group.
