• How to Install Oracle Software on Remote Linux Server

  - by James Taylor

  It is becoming more common these days to install Oracle software on remote Linux servers. This issue has always existed but was generally resolved either by silent installs or by someone physically going to the server to install the software. This is becoming more difficult with the popular virtualisation and cloud deployment strategies. This post provides the steps involved to install Oracle Software using the GUI interface on a remote Linux server. There are many ways to achieve this, the way I resolve this issue is via Virtual Network Computing (VNC) as it is shipped with RedHat and OEL out of the box. For this post I’m using OEL 5 deployed on a OVM guest. If not already done so download and install a client version of VNC so you can connect to the server. There are many out there, for the purpose of this post I use UltraVNC. You can download a free version from http://www.uvnc.com/download/index.html By default VNC Server is installed in your RedHat and OEL OS, but it is not configured. The way VNC works is when started it creates a client instance for the user and binds it to a specific port. So if have an account on the Linux box you can setup a VNC Server session for that user, you don’t need to be root. For the purpose of this document I’m going to use oracle as the user to setup a VNC Session as this is the user I want use to install the software. However to start the VNC Service you must be root. As the root user run the following command: service vncserver start Starting VNC server: no displays configured                [  OK  ] Login to the Linux box as the user  you wan to install the Oracle software [oracle@lisa ~]$ Run the command to create a new VNC server instance for the oracle user: vncserver You will be ask to supply password information. This is what you will enter when connecting from your desktop client. This password is also independent of the actual Linux user password. The VNC Server is acting as a proxy to this instance. You will require a password to access your desktops. Password: Verify: xauth:  creating new authority file /home/oracle/.Xauthority New 'lisa.nz.oracle.com:1 (oracle)' desktop is lisa.nz.oracle.com:1 Creating default startup script /home/oracle/.vnc/xstartup Starting applications specified in /home/oracle/.vnc/xstartup Log file is /home/oracle/.vnc/lisa.nz.oracle.com:1.log As you can see a new instance lisa.nz.oracle.com:1 has been created. If you were to run the vncserver command again another instance lisa.nz.oracle.com:2 will be created. If you are going through a firewall you will need to ensure that the port 5901 (port 1) is open between your client desktop and the Linux Server. Depending on the options chosen at install time a firewall could be in place. The simplest way to disable this is using the command. You will need to be root. service iptables stop This will stop the firewall while you install. If you just want to add a port to the accepted lists use the firewall UI. You will need to be root. system-config-security-level Now you are ready to connect to the server via the VNC. Using the software installed in step one start the VNC Client. You should be prompted for the server and port. If connectivity is established, you will be prompted for the password entered in step 5. You should now be presented with a terminal screen ready to install software Go to the location of the oracle install software and start the Oracle Universal Installer

• iPhone Peripherals for Retailers

  - by David Dorf

  I saw RedLaser on the latest "Shopper" iPhone commercial on TV. Works great for consumers, but retailers will be more interested in a true barcode reader from someone like Infinite Peripherals, which also comes with a magstripe reader I previously mentioned the offerings from Square Verifone, and Mophie that allow swiping credit cards with an iPhone as well. So what's next? There's a decent list at WireLust that includes an IR dongle that turns your iPhone into a TV remote, armband monitors for use when exercising, and most recently a NFC/RFID reader. iCarte from Canadian firm Wireless Dynamics looks interesting. This device can be used for NFC payments and for reading RFID tags. The Canon printer I just bought for home has an iPhone app that lets me send iPhone pictures directly to the printer for printing. In that same vein, Seems like retailers could use bluetooth to print receipts on strategically place printers on the floor. I can't wait to see what they come up with for the iPad.

• Script to establish SSH tunnel and then run another program that uses the tunnel

  - by Rob Hills

  I am running a GUI app (Gnucash) that connects to a remote Postgres database via a secure shell session. I can use the SSH -L command to tunnel a local port and then separately run Gnucash and this works fine. What I'd like to do is use a single shell script that sets up the tunnel and then calls Gnucash. Is that possible? If so, how do I do it? Currently, I run commands like the following in 2 separate terminal windows: ssh -L 5433:127.0.0.1:19097 [email protected] gnucash postgres://gnucash@localhost:5433/gnucash_db If I simply put both lines in a shell script, the first line drops me into the remote shell and the second line doesn't execute until I exit the remote shell. TIA, Rob Hills

• Google Storage for Developers…

  - by joelvarty

  I noticed this today and it seems to be a service that will compete with Amazon S3 and Microsoft’s Azure Blob storage. It’s only open to US developers for now, but I have one burning question: can we transfer directly from Google Storage to another Google service (like YouTube, Docs, etc) without incurring any transfer charges?  The even bigger question is whether all of the APIs will be updated to include this new service and to better amalgamate the existing app services with this one, since storage is so central to everything, it seems to beg the question. via Daring Fireball more later - joel

• Change the User Interface Language in Vista or Windows 7

  - by Matthew Guay

  Would you like to change the user interface language in any edition of Windows 7 or Vista on your computer?  Here’s a free app that can help you do this quickly and easily. If your native language is not the one most spoken in your area, you’ve likely purchased a PC with Windows preinstalled with a language that is difficult or impossible for you to use.  Windows 7 and Vista Ultimate include the ability to install multiple user interface languages and switch between them. However, all other editions are stuck with the language they shipped with.  With the free Vistalizator app, you can add several different interface languages to any edition of Vista or Windows 7 and easily switch between them. Note:  In this test, we used an US English copy of both Windows 7 Home Premium and Windows Vista Home Premium, and it works the same on any edition. The built-in language switching in the Ultimate Editions lets you set a user interface language for each user account, but this will only switch it for all users.  Add a User Interface Language to Windows To add an interface language to any edition of Windows 7 and Vista, first download Vistalizator (link below).  Then, from the same page, download the language pack of your choice.  The language packs are specific for each service pack of Windows, so make sure to choose the correct version and service pack you have installed. Once the downloads are finished, launch the Vistalizator program. You do not need to install it; simply run it and you’re ready to go.  Click the Add languages button to add a language to Windows. Select the user interface language pack you downloaded, and click Open. Depending on the language you selected, it may not automatically update with Windows Update when a service pack is released.  If so, you will have to remove the language pack and reinstall the new one for that service pack at that time.  Click Ok to continue. Make sure you’ve selected the correct language, and click Install language. Vistalizator will extract and install the language pack.  This took around 5 to 10 minutes in our test. Once the language pack is installed, click Yes to make it the default display language. Now, you have two languages installed in Windows.  You may be prompted to check for updates to the language pack; if so, click Update languages and Vistalizator will automatically check for and install any updates. When finished, exit Vistalizator to finish switching the language.  Click Yes to automatically reboot and apply the changes. When you computer reboots, it will show your new language, which in our test is Thai.  Here’s our Windows 7 Home Premium machine with the Thai language pack installed and running. You can even add a right to left language, such as Arabic, to Windows.  Simply repeat the steps to add another language pack.    Vistalizator was originally designed for Windows Vista, and works great with Windows 7 too.  The language packs for Vista are larger downloads than their Windows 7 counterparts.  Here’s our Vista Home Premium in English… And here’s how it looks after installing the Simplified Chinese language pack with Vistalizator. Revert to Your Original Language If you wish to return to the language that your computer shipped with, or want to switch to another language you’ve installed, run Vistalizator again.  Select the language you wish to use, and click Change language.   When you close Vistalizator, you will again be asked to reboot.  Once you’ve rebooted, you’ll see your new (or original) language ready to use.  Here’s our Windows 7 Home Premium desktop, back in it’s original English interface. Conclusion This is a great way to change your computer’s language into your own native language, and is especially useful for expatriates around the world.  Also, if you’d like to simply change or add an input language instead of changing the language throughout your computer, check out our tutorial on How to Add Keyboard Languages to XP, Vista, and Windows 7.

• Xaudio2 XAPO Effects

  - by Jason Champion

  I've been working with XAudio2. After looking at the samples, example code, and sparse documentation available from Microsoft and the MSDN, I've found that there aren't any easy-to-find resources on creating and using XAPO effects, nor any XAPO effects produced by third parties that I can download and/or buy. What it looks like is that if I create an app that uses XAPO effects, I'll have to create them all myself because there's no community of existing applications like there is with technologies like Apple's AU or Steinberg's VST. Is this true, or are there others using XAudio2 and XAPO and I just haven't found them? Is there a place to ask programmer-support-related questions about XAudio2 and related technologies (or is this the best destination)? The best I've found so far are the XNA forums, which are game-specific and sparsely populated in the audio area.

• Adobe flash player not working with Amazon Prime

  - by Alex

  I have ubuntu 12.04 64bit using Google Chrome. I had chromium from the app center then today amazon prime video stopped working. It told me to update Flash. So I uninstalled chromium and installed Google Chrome. Didn't work. Then I downloaded flash for ubuntu via apt. That one gave me a "flash version isn't supported" message. The flash version was 11. Now I tried http://apt.ubuntu.com/p/flashplugin-installer It worked, but right in the middle of the video, it popped the error message again. Sorry we are unable to stream this video. This is likely because your Flash Player needs to be updated. So I don't know what happened.

• Trying to Draw a 2D Triangle in OpenGL ES 2.0

  - by Nathan Campos

  I'm trying to convert a code from OpenGL to OpenGL ES 2.0 (for the BlackBerry PlayBook). So far what I got is this (just the part of the code that should draw the triangle): void setupScene() { glClearColor(250, 250, 250, 1); glViewport(0, 0, 600, 1024); glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); } void drawScene() { setupScene(); glColorMask(0, 0, 0, 1); const GLfloat triangleVertices[] = { 100, 100, 150, 0, 200, 100 }; glVertexAttribPointer(0, 2, GL_FLOAT, GL_FALSE, 0, triangleVertices); glEnableVertexAttribArray(0); glDrawArrays(GL_TRIANGLES, 0, 2); } void render() { drawScene(); bbutil_swap(); } The problem is that when I launch the app instead of showing me the triangle the screen just flickers (very fast) from white to gray. Any idea what I'm doing wrong? Also, here is the entire code if you need: Full source code

• What is the best database design and/or software to model a thesaurus?

They are a type of controlled vocabulary, for indexing or tagging purposes. Such a thesaurus can be used as the basis of an index for online material.

• Domino Dump Turns Into Van Gogh Painting [Video]

  - by Jason Fitzpatrick

  We’ve seen a lot of domino projects in our day, but this is the first one we’ve seen that turns into a piece of classic art when it’s done. Courtesy of domino enthusiast FlippyCat: I recreated Vincent van Gogh’s “Starry Night” from just over 7,000 dominos. The second attempt took about 11 hours total to build. The first attempt failed, when I dropped a screw from the camera rig onto it. I was able to improve the swirling clouds better in the second attempt as a result though. I do not know how long the first attempt took, but I did not have any accidents building like I did in the second attempt! Next up, Edvard Munch’s The Scream?

• Can't download web photo albums to Picasa

  Someone has shared a Picasa web album (Limited, anyone with the link), but I can't download it to Picasa. The following alert appears: Firefox doesn't know how to open this address, because the protocol (picasa) isn't associated with any program. I have Picasa 3.0.0 installed on Ubuntu 11.04, I remember it saying something about registering the picasa protocol with Firefox during the installation. I have Firefox 6.0.2, and these settings are present in about:config network.protocol-handler.app.picasa;/usr/bin/picasa network.protocol-handler.expose.picasa;true network.protocol-handler.external.picasa;true Picasa is located here: $ which picasa /usr/bin/picasa Is there something I can do to make this work?

• Delegates and Events in C#

  - by hakanbilge

  Events and their underlying mechanism "Delegates" are very powerful tools of a developer and Event Driven Programming is one of the main Programming Paradigms. Its wiki definition is "event-driven programming or event-based programming is a programming paradigm in which the flow of the program is determined by events?i.e., sensor outputs or user actions (mouse clicks, key presses) or messages from other programs or threads." That means, your program can go its own way sequentially and in the case of anything that requires attention is done (when an event fires) by somebody or something, you can response it by using that event's controller method (this mechanism is like interrupt driven programming in embedded systems). There are many real world scenarios for events, for example, ASP.NET uses events to catch a click on a button or in your app, controller has notice of a change in UI by handling events exposed by view (in MVC pattern). Delegates in C# C# delegates correspond to function pointers in  [read more....]

• Boost Netbook Speed with an SD Card & ReadyBoost

  - by Matthew Guay

  Looking for a way to increase the performance of your netbook?  Here’s how you can use a standard SD memory card or a USB flash drive to boost performance with ReadyBoost. Most netbooks ship with 1Gb of Ram, and many older netbooks shipped with even less.  Even if you want to add more ram, often they can only be upgraded to a max of 2GB.  With ReadyBoost in Windows 7, it’s easy to boost your system’s performance with flash memory.  If your netbook has an SD card slot, you can insert a memory card into it and just leave it there to always boost your netbook’s memory; otherwise, you can use a standard USB flash drive the same way. Also, you can use ReadyBoost on any desktop or laptop; ones with limited memory will see the most performance increase from using it. Please Note:  ReadyBoost requires at least 256Mb of free space on your flash drive, and also requires minimum read/write speeds.  Most modern memory cards or flash drives meet these requirements, but be aware that an old card may not work with it. Using ReadyBoost Insert an SD card into your card reader, or connect a USB flash drive to a USB port on your computer.  Windows will automatically see if your flash memory is ReadyBoost capable, and if so, you can directly choose to speed up your computer with ReadyBoost. The ReadyBoost settings dialog will open when you select this.  Choose “Use this device” and choose how much space you want ReadyBoost to use. Click Ok, and Windows will setup ReadyBoost and start using it to speed up your computer.  It will automatically use ReadyBoost whenever the card is connected to the computer. When you view your SD card or flash drive in Explorer, you will notice a ReadyBoost file the size you chose before.  This will be deleted when you eject your card or flash drive. If you need to remove your drive to use elsewhere, simply eject as normal. Windows will inform you that the drive is currently being used.  Make sure you have closed any programs or files you had open from the drive, and then press Continue to stop ReadyBoost and eject your drive. If you remove the drive without ejecting it, the ReadyBoost file may still remain on the drive.  You can delete this to save space on the drive, and the cache will be recreated when you use ReadyBoost next time. Conclusion Although ReadyBoost may not make your netbook feel like a Core i7 laptop with 6GB of RAM, it will still help performance and make multitasking even easier.  Also, if you have, say, a memory stick and a flash drive, you can use both of them with ReadyBoost for the maximum benefit.  We have even noticed better battery life when multitasking with ReadyBoost, as it lets you use your hard drive less.  SD cards and thumb drives are relatively cheap today, and many of us have several already, so this is a great way to improve netbook performance cheaply.

• Java PlayFramework & Python Django GAE

  I already know Java, C# and C++. Now I want to start with web development and I saw that some really big sites are built with Python/C++. I like the coding style of Python, it looks really clean, but some other things like no errors before runtime is really strange. However, I don't know what I should learn now. I started with Python but then I saw that Google App Engine also supports Java and the PlayFramework looks amazing too. Now I am really confused. Should I go with Python or Java? I found the IDE for Python "PyCharm" really amazing for web development. Does Java have something similar, eclipse maybe? I know that this question isn't constructive, but it will help me with my decision. What are pro and cons of both languages?

  We’ve seen our fair share of sunrise simulators, but by far this one is the most polished build–everything from the atomic clock circuit to the LEDs are all packed cleanly in a frosted acrylic case. Renaud Schleck, the tinker behind the build, describes the guts: This is an alarm clock simulating the sunrise, which means that a few minutes before the alarm goes off, it shines some light whose brightness increases over time. The alarm clock is built around a MSP430G2553 microcontroller compatible with the MSP430 Launchpad from Texas Instrument. It features a DCF77 module which sets the clock automatically through radio waves.

• How do I convert my matrix from OpenGL to Marmalade?

  - by King Snail

  I am using a third party rendering API, Marmalade, on top of OpenGL code and I cannot get my matrices correct. One of the API's authors states this: We're right handed by default, and we treat y as up by convention. Since IwGx's coordinate system has (0,0) as the top left, you typically need a 180 degree rotation around Z in your view matrix. I think the viewer does this by default. In my OpenGL app I have access to the view and projection matrices separately. How can I convert them to fit the criteria used by my third party rendering API? I don't understand what they mean to rotate 180 degrees around Z, is that in the view matrix itself or something in the camera before making the view matrix. Any code would be helpful, thanks.
