  • 3 column layout with css display table, with first row having multiple rows?

    - by Damainman
    I am working on a new website which: Has 3 columns - Each Column being a cell First column has 3 rows (Logo, Nav, icons) - Has a Div with display: table which wraps arround 3 divs with display:table-row. Other two columns only have 1 row. With the middle column being the content area. However since this is my first time using display:table, I am running into some things that aren't so clear to me. I was trying to avoid floating divs. If I need multiple rows with one cell in each row per column, do I embed each cell in a row or just create each row and not declare cells. I understand that browsers automatically create the missing elements but I want to make sure I do this properly to avoid any side effects that might occur due to the browser automatically creating the missing elements. Edit: I think my brain is just over worked, I guess I can accomplish this by just using 3 divs in the first column instead of using a nested table div with the rows. This just popped into my head.

  • Who can change the View in MVC?

    - by Luke
    I'm working on a thick client graph displaying and manipulation application. I'm trying to apply the MVC pattern to our 3D visualization component. Here is what I have for the Model, View, and Controller: Model - The graph and it's metadata. This includes vertices, edges, and the attributes of each. It does not contain position information, icons, colors, or anything display related. View - This would commonly be called a scene graph. It includes the 3D display information, texture information, color information, and anything else that is related specifically to the visualization of the model. Controller - The controller takes the view and displays it in a Window using OpenGL (but it could potentially be any 3D graphics package). The application has various "layouts" that change the position of the vertices in the display. For instance, one layout may arrange the vertices in a circle. Is it common for these layouts to access and change the view directly? Should they go through the Controller to access the View? If they go through the Controller, should they just ask for direct access to the View or should each change go through the controller? I realize this is a bit different from the standard MVC example where there a finite number of Views. In this case, the View can change in an infinite number of ways. Perhaps I'm shattering some basic principle of MVC here. Thanks in advance!

  • Can't Log Into Ubuntu 12.04

    - by Razick
    Yesterday, after turning on Ubuntu, I logged into a Gnome session. A few minutes later, I tried switching to Unity for a change. Unfortunately, the background and my desktop icons loaded, but the system bar and launcher failed to load even after several minutes. Unity had always worked fine for me. I then tried the guest account, and it worked fine on both Unity and Gnome. However, the problem with my account got worse; I couldn't log into any desktop at all anymore. I would type in my password and press enter and it would just sit there doing nothing. The computer no longer responded in any way, so I had to hold the power button and reboot. The same problem happened repeatedly. Earlier today, I tried to get on again. I found that I hadthe same problem, when I tried to log in, the computer no longer locked up, but instead flashed a black screen with theconsole output and what seemed to be an error message before returning to the log in screen. It was to quick for me to read, about 1/4-1/2 second. I'd really appreciate some help as I have some important files that are not backed up yet. I can't transfer the files to a new account, or even make a new account because I tried taking the password off my account so now I can't authenticate from the guest to perform root functions. I'd really appreciate some help as I have some important files that are not backed up yet. Thanks.

  • Cheap server stress testing

    - by acrosman
    The IT department of the nonprofit organization I work for recently got a new virtual server running CentOS (with Apache and PHP 5), which is supposed to host our website. During the process of setting up the server I discovered that the slightest use of the new machine caused major performance problems (I couldn't extract tarballs without bringing it to a halt). After several weeks of casting about in the dark by tech support, it now appears to be working fine, but I'm still nervous about moving the main site there. I have no budget to work with (so no software or services that require money), although due to recent cut backs I have several older desktops that I could use if it helps. The site doesn't need to withstand massive amounts of traffic (it's a Drupal site just a few thousand visitors a day), but I would like to put it through a bit of it paces before moving the main site over. What are cheap tools that I can use to get a sense if the server can withstand even low levels of traffic? I'm not looking to test the site itself yet, just fundamental operation of the server.

  • Turn a Kindle into a Weather Display Station

    - by Jason Fitzpatrick
    The e-ink display, network connectivity, and low-power consumption of Kindle ebook readers make them a perfect candidate for an infrequently refreshed high-visibility display–like a weather display. Read on to see how to hack a Kindle to serve up the local weather. Tinker and hardware hacker Matt Petroff hacked his Kindle to accept input from a web server and then, graciously and in the spirit of geeky projects everywhere, shared his source code. He explains the heart of the project: The server side of the system uses shell and Python scripts to convert weather forecast data into an image for the Kindle. The scripts first download and parse forecast data from NOAA via the National Digital Forecast Database XML/SOAP Service. After parsing the data, the data then needs to be converted into an image. This is accomplished by preprocessing a specially crafted SVG file to insert temperatures, forecast symbols, and days of the week. This SVG is then rendered as a PNG using rsvg-convert and converted to a grayscale, no transparency color space as required by the Kindle using pngcrush. Finally, it is copied to a public location on the web server. The Kindle is set to refresh twice a day (you could easily tweak the scripts for a more frequent refresh) and displays the forecast as seen in the photo above–with crisp and easy to read text and icons. Hit up the link below for more information and the project’s source code.

  • Need advice concerning Feature Based Development when knowledge DB is involved

    - by voroninp
    We develop BackOffice application which is used to edit our knowledge DB. Now our main product's development team is shifting to the feature based development and we need to support several DB's with not identical data schemes. (DS changes slightly from DB to DB) The information from knowledge Db is extracted by the script and then is distributed to the clients. We also need to support merging these DB's. We now analyze pros and cons of different approaches. We discuss this one: One working DB (WDB) with one DB for each feature branch (FDB). The approved data is moved from WDB to FDB. So we need to support only one script for each branch. This script will extract data from corresponding FDB. Nevertheless we are to code the differences between FDBs and WDB manually. May be some automatic mapping tools exist? I also wish to know whether classic solutions to the alike problems already exist. Can anyone share the best practices for this case?

  • Whole continent simulation [on hold]

    - by user2309021
    Let's suppose I am planning to create a simulation of an entire continent at some point in the past (let's say, around 0 A.D). Is it feasible to spawn a hundred million actors that interact with each other and their environments? Having them reproduce, extract resources, etc? The fact is that I actually want to create a simulation that allows me to zoom in from a view of the entire continent up to a single village, and interact with it. (Think as if you could keep zooming in the campaign map of any Total War game and the transition to the battle map was seamless, not a change of the "game mode"). By the way, I have never made a game in my entire life (I have programmed normal desktop applications, though), so I am really having trouble wrapping my head around how to implement such a thing. Even while thinking about how to implement a simple population simulator, without a graphical interface, I think that the O(n) complexity of traversing an array and telling all people to get one year older each time the program ticks is kind of stupid. Any kind help would be greatly appreciated :) EDIT: After being put on hold, I shall specify a question. How would you implement a simulation of all basic human dynamics (reproduction, resource consumption) in an entire continent (with millions of people)?

  • Will the Driver Support for Intel HD Graphics be Improved in 12.10?

    - by Hiranya
    I recently installed Ubuntu 12.04 on a HP Pavilion dv4 laptop. This is a core i7 machine with Intel HD graphics and also a separate nVidia VGA card. I had a lot of issues getting Ubuntu 12.04 working on this system. First there were issues booting up the live CD for installation. I worked around that by using the 'nomodeset' option. Then I continued to have similar issues after installation has completed. So I had to permanently add the nomodeset option to my GRUB boot configuration. At the moment I have a working installation but there are many issues: Ubuntu GUI is a bit flaky at times. The mouse pointer goes on and off when hovering over certain icons. Certain things doesn't get rendered properly on the screen. I can't access any of the tty consoles. Hitting Ctrl+Alt+F[1-6] gives me a blank screen. And once that happens I can't even come back to the UI by hitting Ctrl+Alt+F7. I've realized that tty consoles are actually working. I just can't see the text. If I enter a command like 'sudo reboot' into the empty screen the machine reboots. Can't get external displays (monitors, projectors etc) working. But I think this is probably because the VGA out is wired to the nVidia card which is not being used by Linux. colord program crashes every now and then triggering a popup message. So my main question is, will the support for Intel HD graphics be improved in the next release? Or will I have to keep using the nomodeset option in the new release too? Also I appreciate if anybody can shed some light on any of the issues listed above. Thanks in advance.

  • Installing Django on Windows

    - by Pranav
    Ever needed to install Django in a Microsoft Windows environment, here is a quick start guide to make that happen: Read through the official Django installation documentation, it might just save you a world of hut down the road. Download Python for your version of Windows. Install Python, my preference here is to put it into the Program Files folder under a folder named Python<Version> Add your chosen Python installation path into your Windows path environment variable. This is an optional step, however it allows you to just type python in the command line and have it fire up the Python interpreter. An easy way of adding it is going into Control Panel, System and into the Environment Variables section. Download Django, you can either download a compressed file or if you’re comfortable with using version control – check it out from the Django Subversion repository. Create a folder named django under your <Python installation directory>\Lib\site-packages\ folder. Using my example above that would have been C:\Program Files\Python25\Lib\site-packages\. If you chose to download the compressed file, open it and extract the contents of the django folder into your newly created folder. If you’d prefer to check it out from Subversion, the normal check out points are http://code.djangoproject.com/svn/django/trunk/ for the latest development copy or a named release which you’ll find under http://code.djangoproject.com/svn/django/tags/releases/. Done, you now have a working Django installation on Windows. At this point, it’d be pertinent to confirm that everything is working properly, which you can do by following the first Django tutorial. The tutorial will make mention of django-admin.py, which is a utility which offers some basic functionality to get you off the ground. The file is located in the bin folder under your Django installation directory. When you need to use it, you can either type in the full path to it or simply add that file path into your environment variables as well. Hope this helps!

  • Ubuntu 12.04 menu bar, nautilus, terminal, and gtk themes not working after installation of Gimp 2.8

    - by Chris
    I installed gimp2.8 from this ppa: ppa:otto-kesselgulasch/gimp after that, my system began having problems. This is my thought process in trying to fix what's happened and the order in which it happened: I noticed the menu bar at the top changed from an opaque black to perfectly clear and the titles of applications and the hidden buttons reacted slowly. No big deal, restarted to see if it fixed it. It didn't, in fact, when the logon screen came up, the password field was grey and boxy like a default windows 98 theme (that's the best I can describe it) as were all the option buttons for gtk programs. I open terminal to try and reinstall gtk, but the terminal is just a black screen with no ability to input commands. I go to a tty and I reinstalled gtk3 and gtk2 (I have both on my system. I don't think they're in conflict, they hadn't been before hand). I restarted. Nothing doing. Log in, nautilus isn't placing icons on my desktop. I click the launcher. It flashes, but no window opens. Try to open by Alt+f2, nothing. I purge ubuntu-desktop, restart, reinstall ubuntu-desktop. Nothing. I have no clue what to do at this point so I'm asking for any help diagnosing the problem and fixing it.

  • Applying Service Pack 1 to Team Foundation Server 2010

    - by Enrique Lima
    Disclosure:  I performed the following activities on my Windows 7 SP1 system, Visual Studio 2010 SP1 and a local Basic installation of TFS 2010. As with any deployment of a service pack into a server environment, take your recommended precautions and be aware of the changes you are putting in.  With that said, make sure you backup your databases, and that you have an exit/rollback strategy in the event of an unexpected situation. Team Foundation Server 2010 Service Pack 1 corresponds to KB2182621.  The KB article is http://support.microsoft.com/kb/2182621 The process will be very simple to follow, you will need to execute the mu_team_foundation_server_2010_sp1_x86_x64_651711.exe file.  That will extract files needed and launch the wizard driven Installation. Once this process completes, you need to validate the changes. By looking at Team Foundation Server 2010 Administration Console, you should see the reference to the KB number and SP1. There is also a good reason to validate log locations and records. From the Team Foundation Server 2010 Administration Console. Or from Windows Explorer, go to the C:\ProgramData\Microsoft\Team Foundation\Server Configuration\Logs location and review the logs referenced by the servicing references.

  • GillSans font doesn't show up in any applications

    - by roboknight
    I am running Ubuntu 10.04, Lucid Lynx, and I'm trying to add some fonts for use with Libre Office. In particular, I've placed a GillSans.ttc font file into /usr/share/fonts/truetype by copying it there with: sudo cp GillSans.ttc /usr/share/fonts/truetype and then attempting to "install" it by updating the font cache: sudo fc-cache -fv That appears to complete successfully, however, the font never seems to be available to either Libre Office, nor fontmatrix. In addition, I tried adding the font to my .fonts directory, thinking that I was somehow seeing a cache of just user supplied fonts, but that isn't the case. The file is a .ttc file, is there some other tools I need to use to extract each font from the .ttc, or is there something else I must do to use a .ttc? Nothing appears to have any issue with the file, but it could be silently failing to do anything. I've looked for the answer in other places, but the only time that a similar question was asked, it did not appear to be answered, so I figured I would ask the question differently and see if anyone else might be able to clue me in on how to use a .ttc font file, if that is possible. A related question, are there any tools to see what font families/font names are contained within a .ttc font file?

  • Dropbox fails to install on Ubuntu 13.10

    - by Fraxav
    I've done some research and it seems Dropbox has some problems with the status icon on Ubuntu 13.10, but I can't even manage to install it. The very first time, I installed nautilus-dropbox from the app center on a freshly installed Saucy, but I couldn't see the status icon and clicking the app icon wouldn't help, so I uninstalled and rebooted. The second and third time, the app just freezed at about 75% while installing from app manager, so I had to shut down the computer and uninstall. Next I tried to install dropbox from the .deb (from website): it installed (the launcher?) from app manager, then the dialog prompted me to start dropbox and finally to download the official daemon, but the download freezed at 0% and made everything else buggy/laggy (probably also because I restarted nautilus, as required, at that point). After a purge and clean from terminal, some icons and this file (which I suspect is somehow responsible, but of course is locked) are still present on my computer. Can anyone help me figure how how to install it? How could I remove that configuration file so I can give it a last shot?

  • How to Edit PDFs?

    - by snowguy
    I typically have two needs: Scenario A. Change a single PDF page. In this case I have a PDF but not the original source file used to create the PDF. I don't want to try to recreate the document from scratch. I'd like to open the PDF and change a few things. A good example of this scenario: I was responsible for planning a big event at a campground site, I had a PDF of the site. I wanted to start with that document, highlight some parts, add some labels, remove some parts that weren't relevant. or Scenario B. Combine PDFs or extract information from a PDF This scenario usually arises because I want a single PDF deliverable that is made up of parts that are best created in different programs. In this case I have the source files for all the documents but they don't play well enough together to easily create a single PDF deliverable. For part of it, I may want to use Libre Office Writer. For another page I may want to use Gimp. Still another page I may use Libre Office Calc. I could use Writer as the master document and embed images or the Calc object into that, but for ultimate control, you can't beat separate PDF documents that are then combined. What are the best tools / processes for editing PDFs in Ubuntu?

  • How to Enable Priority Inbox on Android (and Setup Important-Only Notifications)

    - by The Geek
    Yesterday Google released an updated Gmail application for Android 2.2 phones that supports the Priority Inbox feature—and more importantly, allows you to change your notifications to only alert you for important email. Let’s take a look. Note: If you’ve never used Priority Inbox, you should really give it a try—it rearranges your email into what is and isn’t important, and you can customize how it classifies messages easily. The idea is that it learns over time, so if you send a lot of emails back and forth with somebody, it will know that they are probably important—you can manually adjust the settings as well. To update the Gmail application, you’ll want to head into the Market and access Menu –> Downloads, where you should see Gmail in the list, and it should let you update from there. If you don’t see an update, you’re either not running Android 2.2, or it has already updated automatically Latest Features How-To Geek ETC The 50 Best Registry Hacks that Make Windows Better The How-To Geek Holiday Gift Guide (Geeky Stuff We Like) LCD?

  • TFS API The All New Team Project Picker &ndash; Beautiful!

    - by Tarun Arora
    The Team Project Picker in TFS 2011 looks gorgeous. I specially like the status bar on the working state, at least let’s you know that the project picker is still working on getting the details and of course the new icons for team project collection and team projects are stunning too.     How do I get the Team Project Picker using the TFS API? That is fairly straight forward. Add a reference to the Microsoft.TeamFoundation.Client dll available in C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\ReferenceAssemblies\v2.0 and use the below code, public void ConnectToTfs() { TeamProjectPicker tfsPP = new TeamProjectPicker(TeamProjectPickerMode.MultiProject, false, new UICredentialsProvider()); tfsPP.ShowDialog(); }   Download a sample application here Why does my project picker look different? You might run into an issue, where the project picker looks like the below, When the Team Project Picker is run from inside of VS the colour theme will be picked up from VS itself. When running outside of VS the windows theme colours are used, so there can be differences between the two. Currently there isn’t a way to change that since the dialog itself is not public (just the wrapper that launches the dialog). So don’t be surprised if the Team Project Picker looks different then expected :-]

  • Scripted SOA Diagnostic Dumps for PS6 (11.1.1.7)

    - by ShawnBailey
    When you upgrade to SOA Suite PS6 (11.1.1.7) you acquire a new set of Diagnostic Dumps in addition to what was available in PS5. With more than a dozen to choose from and not wanting to run them one at a time, this blog post provides a sample script to collect them all quickly and hopefully easily. There are several ways that this collection could be scripted and this is just one example. What is Included: wlst.properties: Ant Properties build.xml soa_diagnostic_script.py: Python Script What is Collected: 5 contextual thread dumps at 5 second intervals Diagnostic log entries from the server WLS Image which includes the domain configuration and WLS runtime data Most of the SOA Diagnostic Dumps including those for BPEL runtime, Adapters and composite information from MDS Instructions: Download the package and extract it to a location of your choosing Update the properties file 'wlst.properties' to match your environment Run 'ant' (must be on the path) Collect the zip package containing the files (by default it will be in the script.output location) Properties Reference: oracle_common.common.bin: Location of oracle_common/common/bin script.home: Location where you extracted the script and supporting files script.output: Location where you want the collections written username: User name for server connection pwd: Password to connect to the server url: T3 URL for server connection, '<host>:<port>' dump_interval: Interval in seconds between thread dumps log_interval: Duration in minutes that you want to go back for diagnostic log information Script Package

  • What are the common techniques to handle user-generated HTML modified differently by different browsers?

    - by Jakie
    I am developing a website updater. The front end uses HTML, CSS and JavaScript, and the backend uses Python. The way it works is that <p/>, <b/> and some other HTML elements can be updated by the user. To enable this, I load the webpage and, with JQuery, convert all those elements to <textarea/> elements. Once they the content of the text area is changed, I apply the change to the original elements and send it to a Python script to store the new content. The problem is that I'm finding that different browsers change the original HTML. How do you get around this issue? What Python libraries do you use? What techniques or application designs do you use to avoid or overcome this issue? The problems I found are: IE removes the quotes around class and id attributes. For example, <img class='abc'/> becomes <img class=abc/>. Firefox removes the backslash from the line breaks: <br \> becomes <br>. Some websites have very specific display technicalities, so an insertion of a simple "\n"(which IE does) can affect the display of a website. Example: changing <img class='headingpic' /><div id="maincontent"> to <img class='headingpic'/>\n <div id="maincontent"> inserts a vertical gap in IE. The things I have unsuccessfully tried to overcome these issues: Using either JQuery or Python to remove all >\n< occurences, <br> etc. But this fails because I get different patterns in IE, sometimes a ·\n, sometimes a \n···. In a Python, parse the new HTML, extract the new text/content, insert it into the old HTML so the elements and format never change, just the content. This is very difficult and seems to be overkill.

  • Is The Ease Of Windows Phone Development Ruining Its Image

    - by Tim Murphy
    I was reading an article on Mashable recently by a long time iPhone user who is living solely on a Lumia 920 at the moment and giving her assessment.  One thing that struck a nerve with me was her describing the Windows Phone ecosystem as immature.  She wasn’t saying this because of the number of apps or the big names like most people do.  She means the quality of the apps in the store. This hit a nerve with me.  I find it hard to believe that the majority of app on iOS are of any higher quality than any other platform.  I believe in any ecosystem you are going to find some high end, high quality apps, but the majority by default will be from people who are trying to solve a problem but do not have the resources to have top graphics and full blown testing.  There will also be a large number that are just there trying to trick you into giving up some cash. Does any of the mean that we shouldn’t take notice of this complaint?  Of course not!  We should always strive to publish the best quality apps possible.  Don’t do things like leaving default app icons and backgrounds.  Put a little effort into your design.  You should also spend as much time as possible ensuring against crashes and giving the user the best experience possible.  Think through your apps organization and navigation.  Go the extra step of putting it into beta and letting select people use it and give you feedback before going to full release. Remember, if we want people to appreciate the Windows Phone platform we have to make sure we give them apps that they are going to enjoy using. del.icio.us Tags: Windows Phone,iPhone,iOS,Nokia,Lumia 920,Mashable

  • OpenXML error “file is corrupt and cannot be opened.”

    - by nmgomes
    From time to time I ear some people saying their new web application supports data export to Excel format. So far so good … but they don’t tell the all story … in fact almost all the times what is happening is they are exporting data to a Comma-Separated file or simply exporting GridView rendered HTML to an xls file. Ok … it works but it’s not something I would be proud of. So … yesterday I decided to take a look at the Office Open XML File Formats Specification (Microsoft Office 2007+ format) based on well-known technologies: ZIP and XML. I start by installing Open XML SDK 2.0 for Microsoft Office and playing with some samples. Then I decided to try it on a more complex web application and the “file is corrupt and cannot be opened.” message start happening. Google show us that many people suffer from the same and it seems there are many reasons that can trigger this message. Some are related to the process itself, others with encodings or even styling. Well, none solved my problem and I had to dig … well not that much, I simply change the output file extension to zip and extract the zip content. Then I did the same to the output file from my first sample, compare both zip contents with SourceGear DiffMerge and found that my problem was Culture related. Yes, my complex application sets the Thread.CurrentThread.CurrentCulture  to a non-English culture. For sample purposes I was simply using the ToString method to convert numbers and dates to a string representation but forgot that XML is culture invariant and thus using a decimal separator other than “.” will result in a deserialization problem. I solve the “file is corrupt and cannot be opened.” by using Convert.ToString(object, CultureInfo.InvariantCulture) method instead of the ToString method. Hope this can help someone.

  • How can I get better at explaining complex software processes to developers?

    - by Lostsoul
    I'm really struggling with my software specs. I am not a professional programmer but enjoy doing it for fun and made some software that I want to sell later but I'm not happy with the code quality. So I wanted to hire a real developer to rewrite my software in a more professional way so it will be maintainable by other developers in the future. I read and found some sample specs and made my own by applying their structure to my document and wanted to get my developer friend to read it and give me advice. After an hour and a half he understood exactly what I was trying to do and how I did it(my algorithms,stack,etc.). How can I get better at explaining things to developers? I add many details and explanations for everything(including working code) but I'm unsure the best way I can learn to pass detailed domain knowledge(my software applies big data, machine learning, graph theory to finance). My end goal is to get them to understand as much as possible from the document and then ask anything they do not understand, but right now it seems they need to extract alot of information from me. How can I get better at communicating domain knowledge to developers?

  • VMware Player 5.0 or VMware Workstation 9.0 after upgrade to Ubuntu 12.10

    The upgrade process Upgrading Ubuntu 12.04 to latest version 12.10 - aka Quantal Quetzal - is straight forward and you only need to follow the offical upgrade instructions. Short version on the console looks like this: sudo do-release-upgrade This will update the repository entries, and start the upgrade process. After some minutes or hours of download and installation, you have to reboot your system once to get the new kernel loaded. As time of writing, I'm on '3.5.0-17-generic'. And as with any modification of the kernel version, you have to compile the necessary kernel modules to get VMware Player or Workstation up and running. Usually, this happens the first time you try start your VMware software and that's it. Well, again not so this time. Getting the kernel patch Luckily, the community over VMware is very active and you can get a new kernel patch in the online forums here. Get the download and put in a folder have write permissions. Then you extract the archive on the console like so: tar -xjvf vmware9_kernel35_patch.tar.bz2 Then you change into the newly created folder: cd vmware9_kernel3.5_patch/ And you execute the available shell script as root (superuser) like so: sudo ./patch-modules_3.5.0.sh This will stop any running instances of VMware software, patches the source files and runs the compile process for your active environment. This might take some time depending on your machine, and once completed you can start VMware Player or Workstation as previously. In case that you are going to apply the patch again, the script will simply quit with the following output: /usr/lib/vmware/modules/source/.patched found. You have already patched your sources. Exiting You might remove the .patched file in case that you upgraded/changed your kernel and you need to apply the patch again. Disclaimer: The patch is "as-is" and the patcher is originally created by Artem S. Tashkinov, and later modified by An_tony. Please refer to the VMware forum in case of questions or problems. There are also patches available for older versions of VMware Player or Workstation.

  • Trouble installing Java

    - by BRKsays
    I am running Ubuntu 12.04 LTS. I wanted to install Java and so I downloaded the 32-bit self extracting .bin file from http://www.java.com and tried to install it according to their instruction. First I made the file an executable one. Then created /usr/java/. After that I have to run this command: ./jre-7u<version>-linux-i586.bin. But I'm stuck here. My Java version is Java 6 u32. When I enter the command it says "no such file or directory". What to do? Please help. Also I'm trying to install 32-bit Java on my 64-bit Precise. Could that possibly be the problem? I tried to follow second answer by Jonas Christensen. I tried to open it, it says file is an unknown type. I tried the terminal command: ./jre-6u31-linux-i586.bin. But it gave this: Unpacking... Checksumming... Extracting... ./jre-6u32-linux-i586.bin: 86: ./jre-6u32-linux-i586.bin: ./install.sfx.5736: not found Failed to extract the files. Please refer to the Troubleshooting section of the Installation Instructions on the download page for more information.
