• Dot Matrix printers setup...

  - by Parhs

  Hello! I am using debian which is similar to ubuntu. They have 7 dot matrix printers some very old like this one http://www.omnidatasys.net/product/desc_printer_ti880.htm which works from 1979 daily and at text is faster than many inkjects. I believe that it has his own language... Sending text to serial port (port server) prints garbage. However i think is prints only capital english up to 95 asccii and greek and the rest up to 127 i think greek capital.(special chip ) Sending english capital letters prints garbage i think but i amnt sure... i will try again... The other printer are ESC/P compatible and i use generic epson driver provided from ghostscript... However i think that sending text via lp -dpr1 filename It prints the text as a grafic...Changing from printer font face(courier,times roman etc) or pitch has no effect... I am wondering if is there any work arround for this? In AIX they claim that lp command printed output as text as it prints and cobol programs send raw text to to lp printers . However in AIX they use some custom filters for the printers and has more options for dot matrix printers.. I would like to know if there is a solution for this.. To avoid graphics mode for text and change font face somehow.. The most Straight-through approach would be to use no driver ,just send ESC/P from cobol but this requires too much work... Thank you again!

• Hybrid Graphics on Windows 7/Ubuntu 12.04 Dual Boot

  - by Noob.

  Alright, so here's the situation: I am using an ASUS UL80VT with two graphics cards: Integrated intel graphics and NVIDIA G210M I was running an Ubuntu 12.04 - Windows 7 dual boot (on separate partitions).The machine worked perfectly (including the display drivers) without me needing to install anything special or change any settings. However, my hard drive was corrupted and I lost all my data yesterday, so after it was replaced, I installed Ubuntu 12.04 64x again after installing Windows 7. I booted up Ubuntu after installation, and noticed it was by default using Unity 2D... Gnome 3.4 wasn't working properly either, so I guessed that the NVIDIA G210M driver wasn't installed/working and the OS was instead using the integrated graphics. I checked the "Additional Drivers" thing, but there were no proprietary drivers listed there, so I went to the NVIDIA website, downloaded the driver directly and installed it. I restarted, but there was no change. After this, I read somewhere that I should change my SATA in the BIOS to "Compatible" rather than "Enhanced". This worked fine and fixed the problem (both Unity and Gnome were working perfectly) but then when I tried booting up Windows 7, I recieved the BSOD. So I changed it back to Enhanced, and once again, the NVIDIA 210M graphics isn't working on Ubuntu, but on Windows 7 it is. I do not want to keep changing from Enhanced to Compatible every time I reboot to Ubuntu and neither do I want to simply just use one OS. Note that NVIDIA 210M and integrated graphics work perfectly on Windows 7. Also, I don't care about switching between them, I just want to be able to use the NVIDIA one. What can I do so that both Windows 7 and Ubuntu work and NVIDIA G210M works on Ubuntu?

• Is Movable Type among the most secure PHP blogs? How secure are the various PHP blog applications?

  - by user6025

  Basically I'm trying to find a blog for a website, and security is the highest priority in our case. We don't need any features that I would imagine are special. Wordpress was our first idea, but its reputation precedes it, and though it may have cleaned up its act lately, I'm not seeing much solid evidence. I get the impression that Movable Type (at least the Perl version) has a much better reputation for security than Wordpress (historically at least). I'm not sure I want to take a chance with Wordpress at this point, but is there some objective source I can got to to back up (or counter) the notion that MT is at least among the best? Secunia doesn't recommend using their stats for comparisons, and securityfocus.com doesn't have stats at all that I can see. Searching here http://web.nvd.nist.gov makes MT look way better than WP (at least in 2007), but this site was referenced by MT's own page boasting about their security, so I don't know how relevant it is or how seriously people take it. Any suggestions on sites where I could/should make a somewhat objective comparison?

• Going to UKOUG in December? Meet the Fusion User Experience Advocates

  - by mvaughan

  By Misha Vaughan, Oracle Applications User Experience The Oracle Fusion User Experience Advocates (FXA) will be hosting a roundtable event at UKOUG in December. The FXA program is run by me and Andrew Gilmour, my co-host and fellow team member from the Oracle Applications User Experience group. At this event, our Advocates will be doing the talking -- or rather, answering your questions. If you come to the roundtable, you will find out that the FXA members are a subset of Oracle ACE Directors who have taken on a commitment to participate in deep-dive training on the Oracle Fusion Applications User Experience, and then blend that training into their own areas of expertise – be it applications, Fusion Middleware, or SOA. The Advocates then make themselves available to local special-interest groups and geographic interest groups for public-speaking events, bringing with them a piece of the Fusion Applications user experience story – including demos. Come to the roundtable for a chance to chat with Andrew and me, but more importantly, take this opportunity to meet some of the Advocates firsthand and find out what they can offer to you and your professional group. For more information on the events and presentations that the Applications User Experience team will take part in at UKOUG, visit our Usable Apps Events page.

• how do I make my Dualshock 3 gamepad work in Ubuntu 14.04?

  - by user290527

  When my desktop computer was running Ubuntu 12.04, my PS3 controllers would work with USB. I didn't need to do any special setup. I could just plug it in before I start SuperTuxKart and it would recognize it. I can also do this on my laptop (still running 12.04). Since I gave my desktop a fresh install of Ubuntu 14.04, the controller would never work. I have played with some installed software that I found when looking for information. Here is what I get with xboxdrv: liam@Liam-CustomDesktop:~$ sudo xboxdrv --detach-kernel-driver xboxdrv 0.8.5 - http://pingus.seul.org/~grumbel/xboxdrv/ Copyright © 2008-2011 Ingo Ruhnke <[email protected]> Licensed under GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html> This program comes with ABSOLUTELY NO WARRANTY. This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details. Controller: PLAYSTATION(R)3 Controller Vendor/Product: 054c:0268 USB Path: 003:012 Controller Type: Playstation 3 USB Your Xbox/Xbox360 controller should now be available as: /dev/input/js0 /dev/input/event16 Press Ctrl-c to quit, use '--silent' to suppress the event output So the existence of this controller is acknowledged at on my computer. But it never works for input. In my old installation, I didn't even need to get software like xboxdrv for it to work. I have never tried bluetooth on either computer, but I don't think I even have that on my desktop. So now, how do I make my gamepad work in Ubuntu 14.04?

• Distinction between API and frontend-backend

  - by Jason

  I'm trying to write a "standard" business web site. By "standard", I mean this site runs the usual HTML5, CSS and Javascript for the front-end, a back-end (to process stuff), and runs MySQL for the database. It's a basic CRUD site: the front-end just makes pretty whatever the database has in store; the backend writes to the database whatever the user enters and does some processing. Just like most sites out there. In creating my Github repositories to begin coding, I've realized I don't understand the distinction between the front-end back-end, and the API. Another way of phrasing my question is: where does the API come into this picture? I'm going to list some more details and then questions I have - hopefully this gives you guys a better idea of what my actual question is, because I'm so confused that I don't know the specific question to ask. Some more details: I'd like to try the Model-View-Controller pattern. I don't know if this changes the question/answer. The API will be RESTful I'd like my back-end to use my own API instead of allowing the back-end to cheat and call special queries. I think this style is more consistent. My questions: Does the front-end call the back-end which calls the API? Or does the front-end just call the API instead of calling the back-end? Does the back-end just execute an API and the API returns control to the back-end (where the back-end acts as the ultimate controller, delegating tasks)? Long and detailed answers explaining the role of the API alongside the front-end back-end are encouraged. If the answer depends on the model of programming (models other than the Model-View-Controller pattern), please describe these other ways of thinking of the API. Thanks. I'm very confused.

• IIS cache control header settings

  - by a_m0d

  I'm currently working on a website that is accessed over https. We have recently come across a problem where we are unable to view .pdf files or any other type of file that is sent as an attachment (Content-Disposition:attachment). According to Microsoft Knowledge Base this is due to the fact that Cache-Control is set to no-cache. However, we have a requirement that all pages be fully reloaded every time they are visited, so we have disabled caching on all pages (through our ASP code, not through IIS settings). However, I have made a special case of this one page that shows the attachment, and it now returns a header with Cache-Control:private and the expiry set to 1 minute in the future. This works fine when I test it on my local machine, using https. However, when I deploy it to our test server and try it, the response headers still return Cache-Control:no-cache. There is no firewall or anything between me and the server, so IIS itself must be adding these headers and replacing mine. I have no idea why it would do this, and it doesn't really make any sense, but it seems to be the only option at the moment (I haven't yet found any other place in the code that will change the cache headers). Can anyone point me to a possible place where IIS might be setting these header values?

• Malaysian Airlines bans kids under 12, creates separate cabins in basement of flight

  - by Gopinath

  Kids are lot of fun to watch and play as long as they don’t start crying. Once they start crying it’s tough job for parents to calm them down and for people around it’s painful to be part of it. If it happens to be on a flight, it’s a biggest annoyance one can ever experience. Especially on long journey over night flights, it’s a nightmare for passengers if couple of kids are uncontrollable. After receiving many complaints from its passengers who are disturbed by kids in flight, Malaysian Airlines decided to ban kids under 12 in their regular Economy class cabins of new Airbus A380s. Parents with under 12 years old kids are allowed only in to special kids zone created in the basement of  the multi-storied jumbo flights Airbus A380s. May be parents with under 12 kids does not appreciate this move, but the rest of travellers would be happy. Back in June 2011 Malaysian Airlines banned infants in first class of its Boeing 747-400 jets. The CEO of Malaysian Airlines defended on twitter about the decision as first classers spend pricy amount for a comfortable journey.  So if you are a parent of kids  under 12, think twice before you book tickets on Malaysian Airlines.

• What web technology could I use which would support a decision tree?

  - by Rami Alhamad

  I am a big game development fan but I haven't done any commercial work in the past. I have been asked by a non-profit to look at developing a game similar to the award-winning www.playspent.org They want the following features: support 5 scenarios mobile isn't important but compatibility with older browsers would be a big bonus they want it to be visual and audible bonus is to have it easily modifiable support 4 languages I don't have much knowledge of Flash and would rather avoid using it as a solution. I started breaking down the problem into segments that I will need to examine, they are as follows: ability to read the game flow from a file that they can produce (xml, etc.) db design to store decision tree language challenge browser compatibility I am leaning towards an Google app engine/GWT solution but I am not sure what technology is best for this. I am really hoping to get your opinion/recommendation on my approach and on what technology is best. A special thanks (and beer if you live in Toronto) will be awarded to anyone who can help give me a ballpark estimate on how much such a game should go for. I know it's tough to estimate but any rough figure will help (how much would you charge for building something like playspent.org?) Thanks in advance

  Hi i have a problem trying to install ubuntu. The machine is a CX Ultrabook model CX.21903W Intel I5 with 500GB hard disk, 8 GB ram and 32 GB SSD. From Installing Ubuntu on a Pre-Installed Windows 8 (64-bit) System (UEFI Supported), and according to the steps guide: 1 - We create a partition from Win8 (70 GB) from the own win8 program. 2 - Confirm-SecureBootUEFI=True. 3 - From Win8, shift + Restart and from special menu we selected the UEFI Firmware Setting. 4 - From BIOS Option: ------Option 1) Disable Secure Boot. ------Option 2) Disable UEFI (Not Available) from Option 1: Three ways is available. With Secure Boot enable - We can't even boot ubuntu. A red windows saying Soft unproper signed. With Secure Boot disable - and this config in boot device order: ----1: UEFI: USB ----2: Windows Boot Manger ----3: Others and CSM (Compatibility Support Module): enable - GRUB appears and selecting try Ubuntu then a black windows appears and nothing happens. The same result if install ubuntu is selected. With Secure Boot disable - and this config in boot device order: ----1: USB (No UEFI) ----2: Windows Boot Manger ----3: Others and CSM (Compatibility Support Module): enable - GRUB appears and selecting try Ubuntu, - Ubuntu boots and we can install it even. 5 - Rebooting and just changing the boot order as ----1: Ubuntu [] ----2: Windows Boot Manger ----3: Others then nothings happens. 6 - Booting from LiveUSB again and, as per instructed, making Boot-Repair (A warning windows: Ubuntu is working in legacy mode.). 7 - Saving changes and rebooting, Grub works but selecting Ubuntu, a black windows appears and nothing happens. Selecting Win8, Win8 boots and works. Untill now we can't make the ubuntu installation. Any suggestion will be welcomed. kind regards and thanks in advance.

• What is the best way to "carve" a terrain created from a heightmap?

  - by tigrou

  I have a 3d landscape created from a heightmap. I'd like to "carve" some holes in that terrain. That will allow me to create bridges, caverns and tunnels inside it. That operation will be done in the game editor so it doesn't need to be realtime. In the end, rendering is done using traditional polygons. What would be the best/easiest way to do that ? I already think about several solutions : Solution 1 1) Create voxels from the heightmap (very easy). In other words, fill a 3D array like this : voxels[32][32][32] from the heightmap values. 2) Carve holes in the voxels as i want (easy too). 3) Convert voxels to polygons using some iso-surface extraction technique (like marching cubes). 4) Reduce (decimate) polygons created in 3). This technique seems to be the most promising for giving good results (untested). However the problem with marching cubes is that they tends to produce lots of polygons thus reducing them is mandatory. Implementing 4) also seems not trivial, i have read several papers on the web and it seems pretty complex. I was also unable to find an example, code snippet or something to start writing an algorithm for triangle mesh decimation. Maybe there is a special decimation algorithm (simpler) for meshes created from marching cubes ? Solution 2 1) Create some triangle mesh from the heighmap (easy). 2) Apply severals 3D boolean operation (eg: subtraction with a sphere) to carve the mesh. 3) apply some procedure to reduce polygons (optional). Operation 2) seems to be very complex and to be honest i have no idea how to do that. Also applying many boolean operation seems to be slow and will maybe degrade the triangle mesh every time a boolean operation is applied.

• Donkey Kong Wall Shelves [DIY Project Inspiration]

  - by Asian Angel

  Are you looking for inspiration for a geeky DIY project to get into over the holiday weekend? Then take a look at this fantastic looking set of Donkey Kong wall shelves created by artist Igor Chak! From the website: So here is a Donkey Kong wall, strong, good looking but still has its character. The wall is made out of individual sections; each section is made out of durable but light carbon fiber, anodized aluminum pixels that are joined with strong stainless steel rods and toughened glass tops. The special mounts themselves are made out of steel and can support up to 60 lbs. Igor’s notes and additional images for the project can be found approximately half way down the webpage linked below.

• Legal Web Fonts & Licensing

  - by Phill

  So I'm a little confused in regards to legality of using fonts for web. Often from designers I get a PSD file and it uses a special font, and the font is supplied. However attempting to convert the font using: http://www.fontsquirrel.com/fontface/generator Ends up with a message saying it's blocked by Adobe. Not only that sometimes if the font can be converted, it often looks like crap when viewed in a browser. I assume that the generator is primarily for people to convert their own fonts, but if you purchase the use of a font then you can only use it for Web if the terms allows you to? The fonts used in PSD's are often Adobe Fonts, I can't find anything that suggests I can convert those and use them on the web. So I'm wondering if anyone knows the legal rights around using Photoshop supplied fonts on the web? In addition I'm wondering what resources are available (free/paid) that provide fonts that can be used on the web. Free: http://www.fontsquirrel.com http://www.google.com/webfonts Paid: http://www.fontshop.com This is the only one's I've found so far that aren't cartoon type fonts like what's primarily on www.dafont.com

• Custom Session Management using HashTable

  - by kaleidoscope

  ASP.NET session state lets you associate a server-side string or object dictionary containing state data with a particular HTTP client session. A session is defined as a series of requests issued by the same client within a certain period of time, and is managed by associating a session ID with each unique client. The ID is supplied by the client on each request, either in a cookie or as a special fragment of the request URL. The session data is stored on the server side in one of the supported session state stores, which include in-process memory, SQL Server™ database, and the ASP.NET State Server service. The latter two modes enable session state to be shared among multiple Web servers on a Web farm and do not require server affinity. Implement Custom session Handler you need to follow following process : 1. Create class library which will inherit from  SessionStateStoreProviderBase abstract Class. 2. Implement all abstract Method in your base class. 3.Change Mode of session to “Custom” in web.config file and provide Provider as your Namespace with classname. <sessionState mode=”Custom” customProvider=”Namespace.classname”> <Providers> <add name=”Name” type=”Namespace.classname”> </sessionstate> For more Details Please refer following links :   http://msdn.microsoft.com/en-us/magazine/cc163730.aspx http://msdn.microsoft.com/en-us/library/system.web.sessionstate.sessionstatestoreproviderbase.aspx - Chandraprakash, S Technorati Tags: Chandraprakash,Session state Managment

• When to use http status code 404

  - by Sybiam

  I am working on a project and after arguing with people at work for about more than a hour. I decided to know what people on stack-exchange might say. We're writing an API for a system, there is a query that should return a tree of Organization or a tree of Goals. The tree of Organization is the organization in which the user is present, In other words, this tree should always exists. In the organization, a tree of goal should be always present. (that's where the argument started). In case where the tree doesn't exist, my co-worker decided that it would be right to answer response with status code 200. And then started asking me to fix my code because the application was falling apart when there is no tree. I'll try to spare flames and fury. I suggested to raise a 404 error when there is no tree. It would at least let me know that something is wrong. When using 200, I have to add special check to my response in the success callback to handle errors. I'm expecting to receive an object, but I may actually receive an empty response because nothing is found. It sounds totally fair to mark the response as a 404. And then war started and I got the message that I didn't understand HTTP status code schema. So I'm here and asking what's wrong with 404 in this case? I even got the argument "It found nothing, so it's right to return 200". I believe that it's wrong since the tree should be always present. If we found nothing and we are expecting something, it should be a 404. Extra Also, I believe the best answer to the problem is to create default objects when organizations are created, having no tree shouldn't be a valid case and should be seen as an undefined behavior. There is no way an account can be used without both trees. For that reasons, they should be always present.

• PHP rand function (or not so rand)

  - by Badr Hari

  I was testing PHP rand function to write on a image. Of course the output shows that it's not so random. The code I used: <?php header('Content-Type: image/png'); $lenght = 512; $im = imagecreatetruecolor($lenght, $lenght); $blue = imagecolorallocate($im, 0, 255, 255); for ($y = 0; $y < $lenght; $y++) { for ($x = 0; $x < $lenght; $x++) { if (rand(0,1) == 0) { imagesetpixel($im, $x, $y, $blue); } } } imagepng($im); imagedestroy($im); ?> My question is, if I use image width/lenght (variable $lenght in this example) number like 512, 256 or 1024, it is very clear that it's not so random. When I change the variable to 513 for an example, it is so much harder for human eye to detect it. Why is that? What is so special about these numbers? 512: 513: Edit: I'm running xampp on Windows to test it.

• Problems with icons and shutting down Ubuntu 12.04

  - by Anders

  I recently upgraded from 11-10 to 12.04 as a dual boot (Windows 7) and am having problems with shutting down. I installed from a CD that I burned from the iso file, and to get it to boot from the CD, I needed to install the special help program from Windows that would then recognize the CD as the system booted.The installation gave me my own user account as well as a guest account. For the User account there is no "gear" icon (in the upper RH side) from which to access the shut down menu. Interestingly the icons for the Home folder, the Ubuntu One folder, and the System Settings folder are missing, although there are blank places shows these names if the mouse cursor is positioned over these areas. They will even launch with the press of a key - but no icons are visible. For the Guest account, all of these icons are visible and usable. The problem that occurs in shutting down is that I need to leave the User account, move to the Guest account (so that I can access the top right "gear" icon that has the shut down menu item) and press the shut down button. The problem here is that when the shut own menu appears and I press the confirmation that I wish to shut down the computer, the page blanks (as one might hope in the process of closing down), and then pops up with the log in menu, giving the option of logging in as a User or as a Guest. So the questions are: 1) how do you reinstate the far right top icon from which you can access the shut down drop down menu in the User account page. 2) how do you get the icons to display properly on the Left hand side (Home, Ubuntu One, System Settings, and Workspace Switcher) 3) how do you get the system to turn of when you press the shut down button! Boy oh boy! Thanks a bunch for any help!

• New features for Expression Blend 4 Release Candidate

  - by kaleidoscope

  With Microsoft Expression Blend 4, you can create websites and applications based on Microsoft Silverlight 3 and Microsoft Silverlight 4, and desktop applications based on Windows Presentation Foundation (WPF) 3.5 with Service Pack 1 (SP1) and WPF4. Expression Blend provides new support for prototyping, interactivity through behaviors, special Silverlight functionality, and on-the-fly sample data generation. Expression Blend includes new behaviors that are quickly and easily configured Expression Blend offers new sample data, behaviors, and features of project templates to support the Model-View-ViewModel (MVVM) pattern The MVVM pattern is a way to structure a Silverlight or WPF application so that user interface (UI) objects are as decoupled as possible from the application's data and behavior. This makes it easier for design tasks and development tasks to be performed independently and without breaking each other. Essentially, your UI is the View. You bind objects in the View to properties and commands of the ViewModel, and the View can also call methods on the ViewModel. Compatible with Silverlight 3 and WPF 3.5 with Service Pack 1 (SP1) Interoperate able with Visual Studio.

• New Content: Customer Engagement & Oracle OpenWorld Preview

  - by user462779

  Two new bits of content available on Profit Online: In A Cross-Channel Approach to Consumer Engagement, Cassandra Moren, senior director of consumer goods industry marketing at Oracle, shares her thoughts on how consumer goods manufacturers are reaping benefits from developing a direct relationship with customers: "Consumer goods manufacturers are starting to adapt in ways that mirror retailers. They are making investments in innovative technologies and processes to build the infrastructure to support the market demand. With advances in aspects like social networking, digital marketing and mobility fundamentally changing the way consumers behave, the door has opened to building a more direct relationship with their customers." We've also published a Special Report on Oracle OpenWorld that gives a great overview of recommendations for must-see sessions and insider advice from experienced attendees. For example, this top from John Matelski, newly elected president of the Independent Oracle Users Group: “Based on developments of the last 12 months, I think big data is definitely going to be hot. The challenges and opportunities of data governance will be another biggie. And there will obviously be a big emphasis on Oracle Exadata and the other Oracle Engineered Systems, with more than 100 sessions.” More updates to come as we continue to add content to Profit Online on a regular basis. Thanks for reading!

• 2D Collision masks for handling slopes

  - by JiminyCricket

  I've been looking at the example at: http://create.msdn.com/en-US/education/catalog/tutorial/collision_2d_perpixel and am trying to figure out how to adjust the sprite once a collision has been detected. As David suggested at XNA 4.0 2D sidescroller variable terrain heightmap for walking/collision, I made a few sensor points (feet, sides, bottom center, etc.) and can easily detect when these points actually collide with non-transparent portions of a second texture (simple slope). I'm having trouble with the algorithm of how I would actually adjust the sprite position based on a collision. Say I detect a collision with the slope at the sprite's right foot. How can I scan the slope texture data to find the Y position to place the sprite's foot so it is no longer inside the slope? The way it is stored as a 1D array in the example is a bit confusing, should I try to store the data as a 2D array instead? For test purposes, I'm thinking of just using the slope texture alpha itself as a primitive and easy collision mask (no grass bits or anything besides a simple non-linear slope). Then, as in the example, I find the coordinates of any collisions between the slope texture and the sprite's sensors and mark these special sensor collisions as having occurred. Finally, in the case of moving up a slope, I would scan for the first transparent pixel above (in the texture's Ys at that X) the right foot collision point and set that as the new height of the sprite. I'm a little unclear also on when I should make these adjustments. Collisions are checked on every game.update() so would I quickly change the position of the sprite before the next update is called? I also noticed several people mention that it's best to separate collision checks horizontally and vertically, why is that exactly? Open to any suggestions if this is an inefficient or inaccurate way of handling this. I wish MSDN had provided an example of something like this, I didn't know it would be so much more complex than NES Mario style pure box platforming!

They wanted to use social media to accomplish this. NBC Sports recognized that sports in inherently social. When you watch a game at the stadium or at home, you’re chatting with the people around you, commenting on plays, and celebrating together after each score. NBC Sports wanted to deliver this same social experience via social media channels. NBC Sports used Oracle Social Relationship Management (SRM) to create an online sporting community on Facebook. Fans can watch sporting events live on NBC television while participating in fan commentary about the event on Facebook. The online fan community is extremely engaged – much like fans in a sporting stadium would be during a game. NBC Sports also pose sporting questions, provide sporting news, and tie-in special promotions with their advertisers to their fans via Facebook. Since implementing their social strategy, NBC Sports has seen their fans become more engaged, their television audience grow, and their advertisers happier with new social offerings.
