  • How do I get a CardScan 60 II working with SANE?

    - by TiuTalk
    I have a CardScan 60 II device and installed SANE in my Ubuntu 10.10 laptop. The problem is I can't make scanimage find the device. Quote: $ sudo sane-find-scanner # sane-find-scanner will now attempt to detect your scanner. If the # result is different from what you expected, first make sure your # scanner is powered up and properly connected to your computer. # No SCSI scanners found. If you expected something different, make sure that # you have loaded a kernel SCSI driver for your SCSI adapter. found USB scanner (vendor=0x08f0 [Corex Technologies Corporation], product=0x1000 [Corex CardScan 60], chip=LM9832/3) at libusb:006:002 # Your USB scanner was (probably) detected.

  • Customize Your WordPress Blog & Build an Audience

    - by Matthew Guay
    Want to quickly give your blog a fresh coat of paint and make it stand out from the pack?  Here’s how you can customize your WordPress blog and make it uniquely yours. WordPress offers many features that help you make your blog the best it can be.  Although it doesn’t offer as many customization features as full WordPress running on your own server, it still makes it easy to make your free blog as professional or cute as you like.  Here we’ll look at how you can customize features in your blog and build an audience. Personalize Your Blog WordPress make it easy to personalize your blog.  Most of the personalization options are available under the Appearance menu on the left.  Here we’ll look at how you can use most of these. Add New Theme WordPress is popular for the wide range of themes available for it.  While you cannot upload your own theme to your blog, you can choose from over 90 free themes currently available with more added all the time.  To change your theme, select the Themes page under Appearance. The Themes page will show random themes, but you can choose to view them in alphabetical order, by popularity, or how recently they were added.  Or, you can search for a theme by name or features. One neat way to find a theme that suites your needs is the Feature Filter.  Click the link on the right of the search button, and then select the options you want to make sure your theme has.  Click Apply Filters and WordPress will streamline your choices to themes that contain these features. Once you find a theme you like, click Preview under its name to see how your blog will look. This will open a popup that shows your blog with the new theme.  Click the Activate link in the top right corner of the popup if you want to keep this theme; otherwise, click the x in the top left corner to close the preview and continue your search for one you want.   Edit Current Theme Many of the themes on WordPress have customization options so you can make your blog stand out from others using the same theme.  The default theme Twenty Ten lets you customize both the header and background image, and many themes have similar options. To choose a new header image, select the Header page under Appearance.  Select one of the pre-installed images and click Save Changes, or upload your own image. If you upload an image larger than the size for the header, WordPress will let you crop it directly in the web interface.  Click Crop Header when you’ve selected the portion you want for the header of your blog. You can also customize your blog’s background from the Background page under Appearance.  You can upload an image for the background, or can enter a hex value of a color for a solid background.  If you’d rather visually choose a color, click Select a Color to open a color wheel that makes it easy to choose a nice color.  Click Save Changes when you’re done. Note: that all themes may not contain these customization options, but many are flexible.  You cannot edit the actual CSS of your theme on free WordPress blogs, but you you can purchase the Custom CSS Upgrade for $14.97/year to add this ability. Add Widgets With Extra Content Widgets are small addons for your blog, similar to Desktop Gadgets in Windows 7 or Dashboard widgets in Mac OS X.  You can add widgets to your blog to show recent Tweets, favorite Flickr pictures, popular articles, and more.  To add widgets to your blog, open the Widgets page under Appearance. You’ll see a variety of widgets available in the main white box.  Select one you want to add, and drag it to the widget area of your choice.  Different themes may offer different areas to place Widgets, such as the sidebar or footer. Most of the widgets offer configuration options.  Click the down arrow beside its name to edit it.  Set them up as you wish, and click Save on the bottom of the widget. Now we’ve got some nice dynamic content on our blog that’s automatically updated from the net. Choose Blog Extras By default, WordPress shows previews of websites when visitors hover over links on your blog, uses a special mobile theme when people visit from a mobile device, and shows related links to other blogs on the WordPress network at the end of your posts.  If you don’t like these features, you can disable them on the Extras page under Appearance. Build Your Audience Now that your blog is looking nice, we can make sure others will discover it.  WordPress makes it easy for you to make your site discoverable on search engines or social network, and even gives you the option to keep your site private if you’d prefer.  Open the Privacy page under Tools to change your site’s visibility.  By default, it will be indexed by search engines and be viewable to everyone.  You can also choose to leave your blog public but block search engines, or you can make it fully private. If you choose to make your blog private, you can enter up to 35 usernames of people you want to be able to see it.  Each private visitor must have a WordPress.com account so they can login.  If you need more than 35 private members, you can upgrade to allow unlimited private members for $29.97/year. Then, if you do want your site visible from search engines, one of the best ways to make sure your content is discovered by search engines is to register with their webmaster tools.  Once registered, you need to add your key to your site so the search engine will find and index it.  On the bottom of the Tools page, WordPress lets you enter your key from Google, Bing, and Yahoo! to make sure your site is discovered.  If you haven’t signed up with these tools yet, you can signup via the links on this page as well. Post Blog Updates to Social Networks Many people discover the sites they visit from friends and others via social networks.  WordPress makes it easy to automatically share links to your content on popular social networks.  To activate this feature, open the My Blogs page under Dashboard. Now, select the services you want to activate under the Publicize section.  This will automatically update Yahoo!, Twitter, and/or Facebook every time you publish a new post. You’ll have to authorize your connection with the social network.  With Twitter and Yahoo!, you can authorize them with only two clicks, but integrating with Facebook will take several steps.   If you’d rather share links yourself on social networks, you can get shortened URLs to your posts.  When you write a new post or edit an existing one, click the Get Shortlink button located underneath the post’s title. This will give you a small URL, usually 20 characters or less, that you can use to post on social networks such as Twitter.   This should help build your traffic, and if you want to see how many people are checking out your site, check out the stats on your Dashboard.  This shows a graph of how many people are visiting, and popular posts.  Click View All if you’d like more detailed stats including search engine terms that lead people to your blog. Conclusion Whether you’re looking to make a private blog for your group or publish a blog that’s read by millions around the world, WordPress is a great way to do it for free.  And with all of the personalization options, you can make your it memorable and exciting for your visitors. If you don’t have a blog, you can always signup for a free one from WordPress.com.  Also make sure to check out our article on how to Start Your Own Blog with WordPress.

  • DFS keeps constantly replicating almost all files

    - by Adrian Godong
    We have always had problems with DFS, but recently it has gotten worse (with no apparent reason) to the point it's becoming harmful. We have one master server and DFS connections to other four servers. The four severs don't modify any files, so all replications always propagate from the master to the four other servers. The replicated directory has about 900,000 files. In the recent weeks, every time we check DFS, the DSF backlogs have hundredths of thousand of files. For instance now, the master server now replicates about 700,000 to three of the four servers while the fourth one is fine. Sometimes, only one is off, sometimes two and this time three. Also, it is never the same set of servers. It is inconceivable that something periodically touches all 900,000 files. The biggest change which happens is a scheduled update of several thousand files every six hours. Does anybody have the same problem? Is it a known issue?

  • Dynamic Forms: Pattern or AntiPattern?

    - by Segfault
    I'm sure you've seen it. The database has a bunch of tables called Forms, Controls,FormsControls, ControlSets, Actions and the program that queries these tables has a dynamically generated user interface. It will read all the forms, load a home page that has links to them all, or embed them in some tabbed or paged home page, and for each of those forms it will read the various text boxes, check boxes, radio buttons, submit buttons, combo boxes, labels and whatnot from the controls and form-to-control join tables, lay those elements out according to the database and link all the controls to logic according to other rules in the database. To me, this is an anti-pattern. It actually make the application more difficult to maintain because the design of it is now spread out into multiple different systems. Also, the database is not source controlled. Sure, it may make one or two changes go more quickly, after you've analyzed the program anyway to understand how to change the data and as long as you don't stray from the sort of changes that were anticipated and accounted for, but that's often just not sustainable. What say you?

  • Different block sizes for partition and underlying logical disk on HP Raid Controller (Linux)

    - by Wawrzek
    Following links collected in this thread I started to check blockdev and found the following output indicating different sizes for partition c0d9p1 and the underlying device (c0d9): [root@machine ~]# blockdev --report /dev/cciss/c0d9 RO RA SSZ BSZ StartSec Size Device rw 256 512 4096 0 3906963632 /dev/cciss/c0d9 [root@machine ~]# blockdev --report /dev/cciss/c0d9p1 RO RA SSZ BSZ StartSec Size Device rw 256 512 2048 1 3906959039 /dev/cciss/c0d9p1 We have a lot of small files, so yes the block size is smaller than normal. The device is a logical driver on an HP P410 raid controller, simple disk without any raid - RAID 0 on one disk to be precise. (Please note that above configuration is a feature not a bug). Therefore, I have the following questions. Can the above discrepancy in the block size affect disk performance? Can I control the block size using hpacucli?

  • How can I tell if a KB or newer has been installed for Windows?

    - by IguyKing
    I have a Windows system that I need to audit. The requirements is that (for example) KB2160329 has been installed onto the system. I know from lots of digging that KB2731847 that we have installed in the environment superseded the earlier KB. MSkbfiles.com works if you know the file name such as TCPIP.SYS. Doesn't do anything if you are just looking for KB Hotfixes. How can I say feed in a script that I'm looking for KB2160329 and it can check for superseded patches? Or is there a website somewhere that I'm missing? [Edited 7 May 2014 8:54am CST] I'm looking for a way to say that KB2731847 which is on the system does fix the same issue (plus more fixes) as KB2160329 which is not in the list as being installed on the system.

  • Windows 7 64bit keyboard issues

    - by Scott
    I have a Pavilion dv4 notebook running Windows 7 64bit Enterprise edition. This morning I started to notice some really strange behavior in how it handled its built-in keyboard. At random intervals there will be a long delay in key presses, to which some keys will never show and other keys will continue to repeat until you hit the backspace. Other keys get mapped incorrectly to other keys. If I hook up an external keyboard the problem does not appear. Before I reformat the machine and do a fresh install, I thought I would check here to see if anyone has experienced this same issue and if so, how did you fix it?

  • Why isn't sox able to convert to mp3?

    - by marue
    I installed Sox, i installed lame-398, but sox is not able to convert any file to mp3. It fails with the messages: ./../sox FAIL util: Unable to load LAME encoder library (libmp3lame). ./../sox FAIL formats: can't open output file `funktech.mp3': How can i check if lame has been installed correct? How can i get sox to find the mp3Library? edit: I did not install sox at all, it works without installing directly from the commandline. Lame was installed by following the instructions on their site: ./configure make make install which results in the following files being found in /usr/local/lib/ : libmp3lame.dylib, libmp3lame.la, libmp3lame.a Maybe symlinking libmp3lame.la, which is marked as executable, to /usr/bin would help?

  • Manage SQL Server Connectivity through Windows Azure Virtual Machines Remote PowerShell

    - by SQLOS Team
    Manage SQL Server Connectivity through Windows Azure Virtual Machines Remote PowerShell Blog This blog post comes from Khalid Mouss, Senior Program Manager in Microsoft SQL Server. Overview The goal of this blog is to demonstrate how we can automate through PowerShell connecting multiple SQL Server deployments in Windows Azure Virtual Machines. We would configure TCP port that we would open (and close) though Windows firewall from a remote PowerShell session to the Virtual Machine (VM). This will demonstrate how to take the advantage of the remote PowerShell support in Windows Azure Virtual Machines to automate the steps required to connect SQL Server in the same cloud service and in different cloud services.  Scenario 1: VMs connected through the same Cloud Service 2 Virtual machines configured in the same cloud service. Both VMs running different SQL Server instances on them. Both VMs configured with remote PowerShell turned on to be able to run PS and other commands directly into them remotely in order to re-configure them to allow incoming SQL connections from a remote VM or on premise machine(s). Note: RDP (Remote Desktop Protocol) is kept configured in both VMs by default to be able to remote connect to them and check the connections to SQL instances for demo purposes only; but not actually required. Step 1 – Provision VMs and Configure Ports   Provision VM1; named DemoVM1 as follows (see examples screenshots below if using the portal):   Provision VM2 (DemoVM2) with PowerShell Remoting enabled and connected to DemoVM1 above (see examples screenshots below if using the portal): After provisioning of the 2 VMs above, here is the default port configurations for example: Step2 – Verify / Confirm the TCP port used by the database Engine By the default, the port will be configured to be 1433 – this can be changed to a different port number if desired.   1. RDP to each of the VMs created below – this will also ensure the VMs complete SysPrep(ing) and complete configuration 2. Go to SQL Server Configuration Manager -> SQL Server Network Configuration -> Protocols for <SQL instance> -> TCP/IP - > IP Addresses   3. Confirm the port number used by SQL Server Engine; in this case 1433 4. Update from Windows Authentication to Mixed mode   5.       Restart SQL Server service for the change to take effect 6.       Repeat steps 3., 4., and 5. For the second VM: DemoVM2 Step 3 – Remote Powershell to DemoVM1 Enter-PSSession -ComputerName condemo.cloudapp.net -Port 61503 -Credential <username> -UseSSL -SessionOption (New-PSSessionOption -SkipCACheck -SkipCNCheck) Your will then be prompted to enter the password. Step 4 – Open 1433 port in the Windows firewall netsh advfirewall firewall add rule name="DemoVM1Port" dir=in localport=1433 protocol=TCP action=allow Output: netsh advfirewall firewall show rule name=DemoVM1Port Rule Name:                            DemoVM1Port ---------------------------------------------------------------------- Enabled:                              Yes Direction:                            In Profiles:                             Domain,Private,Public Grouping:                             LocalIP:                              Any RemoteIP:                             Any Protocol:                             TCP LocalPort:                            1433 RemotePort:                           Any Edge traversal:                       No Action:                               Allow Ok. Step 5 – Now connect from DemoVM2 to DB instance in DemoVM1 Step 6 – Close port 1433 in the Windows firewall netsh advfirewall firewall delete rule name=DemoVM1Port Output: Deleted 1 rule(s). Ok. netsh advfirewall firewall show  rule name=DemoVM1Port No rules match the specified criteria.   Step 7 – Try to connect from DemoVM2 to DB Instance in DemoVM1  Because port 1433 has been closed (in step 6) in the Windows Firewall in VM1 machine, we can longer connect from VM3 remotely to VM1. Scenario 2: VMs provisioned in different Cloud Services 2 Virtual machines configured in different cloud services. Both VMs running different SQL Server instances on them. Both VMs configured with remote PowerShell turned on to be able to run PS and other commands directly into them remotely in order to re-configure them to allow incoming SQL connections from a remote VM or on on-premise machine(s). Note: RDP (Remote Desktop Protocol) is kept configured in both VMs by default to be able to remote connect to them and check the connections to SQL instances for demo purposes only; but not actually needed. Step 1 – Provision new VM3 Provision VM3; named DemoVM3 as follows (see examples screenshots below if using the portal): After provisioning is complete, here is the default port configurations: Step 2 – Add public port to VM1 connect to from VM3’s DB instance Since VM3 and VM1 are not connected in the same cloud service, we will need to specify the full DNS address while connecting between the machines which includes the public port. We shall add a public port 57000 in this case that is linked to private port 1433 which will be used later to connect to the DB instance. Step 3 – Remote Powershell to DemoVM1 Enter-PSSession -ComputerName condemo.cloudapp.net -Port 61503 -Credential <UserName> -UseSSL -SessionOption (New-PSSessionOption -SkipCACheck -SkipCNCheck) You will then be prompted to enter the password.   Step 4 – Open 1433 port in the Windows firewall netsh advfirewall firewall add rule name="DemoVM1Port" dir=in localport=1433 protocol=TCP action=allow Output: Ok. netsh advfirewall firewall show rule name=DemoVM1Port Rule Name:                            DemoVM1Port ---------------------------------------------------------------------- Enabled:                              Yes Direction:                            In Profiles:                             Domain,Private,Public Grouping:                             LocalIP:                              Any RemoteIP:                             Any Protocol:                             TCP LocalPort:                            1433 RemotePort:                           Any Edge traversal:                       No Action:                               Allow Ok.   Step 5 – Now connect from DemoVM3 to DB instance in DemoVM1 RDP into VM3, launch SSM and Connect to VM1’s DB instance as follows. You must specify the full server name using the DNS address and public port number configured above. Step 6 – Close port 1433 in the Windows firewall netsh advfirewall firewall delete rule name=DemoVM1Port   Output: Deleted 1 rule(s). Ok. netsh advfirewall firewall show  rule name=DemoVM1Port No rules match the specified criteria.  Step 7 – Try to connect from DemoVM2 to DB Instance in DemoVM1  Because port 1433 has been closed (in step 6) in the Windows Firewall in VM1 machine, we can no longer connect from VM3 remotely to VM1. Conclusion Through the new support for remote PowerShell in Windows Azure Virtual Machines, one can script and automate many Virtual Machine and SQL management tasks. In this blog, we have demonstrated, how to start a remote PowerShell session, re-configure Virtual Machine firewall to allow (or disallow) SQL Server connections.

  • How can I make it difficult to install a new operating system on a certain computer?

    - by D W
    I want to host a website on a desktop computer running Ubuntu with a Windows virtual machine. I will give away the computer in exchange for a number of months of remote web hosting. I want to add some kind of lock (hardware or otherwise) so that the end users will have difficulty just reinstalling Windows and using the machine as they want, in contradiction to the contract. Ideally, I'd want the machine to die if reinstallation of the OS is attempted. It doesn't have to be completely insurmountable, but it has to be difficult enough to prevent casual reinstallation. Perhaps on bootup the system can check whether certain files exist on the computer and refuse to boot if they do not. I don't know if this is possible, but maybe BIOS is password protected, and searches for files before boot up. The files it looks for could be date sensitive, i.e. require remote replacement on a schedule.

  • How to easily upgrade MySQL 5.0.32 to MySQL 5.1.20 or higher on Debian Etch?

    - by Ferdy
    I have a home server running Debian Etch with MySQL 5.0.32 on it. I'm not much of a Linux administrator but two years ago I installed the server and it runs fine. I used the official MySQL package for Debian at that time. Since then I have been happily making use of it. Now I need to use a MySQL function that is only available in MySQL 5.1.20 and higher. Therefore I would like to upgrade. I'm not that confident in messing with something I need every day so I wanted to check with you what the best upgrade path would be? Obviously I prefer a simple upgrade that keeps my database, users and settings in place as they are now.

  • Business Objects - Containers or functional?

    - by Walter
    This is a question I asked a while back on SO, but it may get discussed better here... Where I work, we've gone back and forth on this subject a number of times and are looking for a sanity check. Here's the question: Should Business Objects be data containers (more like DTOs) or should they also contain logic that can perform some functionality on that object. Example - Take a customer object, it probably contains some common properties (Name, Id, etc), should that customer object also include functions (Save, Calc, etc.)? One line of reasoning says separate the object from the functionality (single responsibility principal) and put the functionality in a Business Logic layer or object. The other line of reasoning says, no, if I have a customer object I just want to call Customer.Save and be done with it. Why do I need to know about another class to save a customer if I'm consuming the object? Our last two projects have had the objects separated from the functionality, but the debate has been raised again on a new project. Which makes more sense and why??

  • Installation taking a very long time, hangs at "Configuring bcmwl-kernel-source"

    - by user290522
    I am installing Ubuntu 14.04(32-bit) on my laptop (Compaq Presario V2000), and after about 7 hours, it is still in Configuring bcmwl-kernel-source (i386) mode. The messages I read are as follows: ubuntu kernel: [22814.858163] ACPI: \_SB_.PCI0.LPC0.LPC0.ACAD: ACPI_NOTIFY_BUS_CHECK event: unsupported with the numbers in the square brackets increasing. I have had Windows XP professional on this laptop, and I am erasing it. I am not sure if I should turn off the laptop, and start all over again. About 4 years ago I installed Ubuntu on this laptop, and that was very fast. The only problem I encountered was my wireless, and could not make it to work, and switched back to Windows. I appreciate any comments regarding this installation taking such a long time. After 40 hours the installation was still in configuring mode with the following messages: ubuntu CRON[29329]: (root) CMD ( cd/ && run-part .. report /etc/cron-hourly) I did the following to check for errors: pressed ctrl-alt-f2. This time the system froze. I had no other choice but to turn off the laptop, and start all over again. The exact model of the laptop is "Compaq Presario V2069CL Notebook PC" with AMD processor.

  • AWS RDS MySQL remote connection extremely slow

    - by nute
    I have a site hosted on AWS EC2 (Elastic Beanstalk), with a MySQL database hosted on AWS RDS. Everything works fine on the production server, fast and all. However when I try to connect remotely from my local machine, it sometimes gets extremely slow (like 4 minutes to load the list of tables), or simply times out. I added my IP in the security group (which I did correctly, since it sometimes works). When it doesn't work, I at the same time check the prod server and it still looks good.

  • Welcome to the Weblog on Oracle ADF Mobile!

    - by joe.huang
    Welcome to ADF Mobile team's weblog.  My name is Joe Huang - I am the product manager for ADF Mobile.  Oracle ADF Mobile is a part of Oracle's Application Development Framework (ADF) that support the development of enterprise/business applications that run on mobile devices.  The development tool for this framework is of course Oracle JDeveloper.  As some of you may know, we currently support the development of mobile browser-based application - this part of product is called ADF Mobile Browser.  Additionally, we are close to release a technology preview of ADF Mobile Client, which supports development of on-device, disconnect capable mobile applications.  What's truly unique about ADF Mobile development process is that it's a very visual and declarative experience, while still allow power Java developers to completely extend the framework to their liking.  The framework also provides a rich set of services needed by an enterprise-grade mobile application - these services would literally take years to implement if they are to be built from the ground up.  However, by using JDeveloper and ADF Mobile, you get the entire framework at your service!In the coming entries, the ADF Mobile product development team will publish any news, best practices, our observation on mobile technology trends, or just our experiences in playing with "gadgets".  Be sure to check back on this page!Sincerely,Joe HuangOracle

  • 2D Side Scrolling game and "walk over ground" collision detection

    - by Fire-Dragon-DoL
    The question is not hard, I'm writing a game engine for 2D side scrolling games, however I'm thinking to my 2D side scrolling game and I always come up with the problem of "how should I do collision with the ground". I think I couldn't handle the collision with ground (ground for me is "where the player walk", so something heavily used) in a per-pixel way, and I can't even do it with simple shape comparison (because the ground can be tilted), so what's the correct way? I'know what tiles are and i've read about it, but how much should be big each tile to not appear like a stairs?Are there any other approach? I watched this game and is very nice how he walks on ground: http://www.youtube.com/watch?v=DmSAQwbbig8&feature=player_embedded If there are "platforms" in mid air, how should I handle them?I can walk over them but I can't pass "inside". Imagine a platform in mid air, it allows you to walk over it but limit you because you can't jump in the area she fits Sorry for my english, it's not my native language and this topic has a lot of keywords I don't know so I have to use workarounds Thanks for any answer Additional informations and suggestions: I'm doing a game course in this period and I asked them how to do this, they suggested me this approach (a QuadTree): -All map is divided into "big nodes" -Each bigger node has sub nodes, to find where the player is -You can find player's node with a ray on player position -When you find the node where the player is, you can do collision check through all pixels (which can be 100-200px nothing more) Here is an example, however i didn't show very well the bigger nodes because i'm not very good with photoshop :P How is this approach?

  • How do you use environment variables, such as %CommonProgramFiles%, in the PATH and have them recognized by services.exe?

    - by Brad Knowles
    I'm trying to add C:\Program Files\Common Files\xxx\xxx to the system PATH environment variable by appending %CommonProgramFiles%\xxx\xxx to the existing path. After rebooting, I open a command prompt and check the PATH. It expands correctly. However, when using Process Explorer from Sysinternals to view the Environment variables on services.exe, it shows the unexpanded version. Coincidentally, the paths using %SystemRoot% expand and are recognized just fine. I've tried altering the PATH through the Environment Variables window from System Properties and through direct Registry manipulation, neither seems to work. Is it possible to use other environment variables, besides %SystemRoot% in PATH and have services.exe understand it?

  • How do I add missing dictionaries for aspell?

    - by Ahmed
    Aspell version: $ aspell -v @(#) International Ispell Version 3.1.20 (but really Aspell 0.60.6) Dump dict yields no results: $ aspell dump dicts First noticed the problem when I did this, was originally working on web server, but someone updated something and it hasn't worked since: $ aspell check temp_test_file.txt Error: No word lists can be found for the language "en_US". What's the proper way of installing the required dictionaries? I believe we're running this on CentOS. And also, /usr/lib/aspell-0.60 does not contain the required dictionaries (provided that they're supposed to be saved there). data-dir: /usr/lib/aspell-0.60

  • Other user SSHed from my hardware

    - by Alex
    While logged into our HPC cluster I used w to check out who else was logged in. I happened to notice that it looks like there's another user logged in from my (personal) computer; 19:04:47 up 40 days, 6:39, 44 users, load average: 0.10, 0.14, 0.18 USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT ME pts/4 zerg.neuron12. 18:55 0.00s 0.09s 0.04s w SOMEONE_ELSE pts/35 zerg.neuron12. Sat14 2:27m 0.08s 0.08s -bash Is this something I should be worried out - I tried to kill the other session but had a permission denied message. Is it possible we just both have the same hardware name? I'd have thought that if this were the case the server would give one of us a different name (e.g. zerg1) when we logged in to prevent confusion. This is not an area I have any experience with, so any advice would be greatly appreciated!

  • What is "Open" anyway?

    - by EmbeddedInsider
    This terms is often used with many meanings.  For example, some people consider Flash 'open' and 'multi-platform' .  But Flash is a product of Adobe systems, locked down, copy protected and distribution restricted.  And versions for other than standard PC, home use, may carry licence fees. Check it out: 3.1 Adobe Runtime Restrictions. You will not use any Adobe Runtime on any non-PC device or with any embedded or device version of any operating system. For the avoidance of doubt, and by example only, you may not use an Adobe Runtime on any (a) mobile device, set top box (STB), handheld, phone, web pad, tablet and Tablet PC (other than with Windows XP Tablet PC Edition and its successors), game console, TV, DVD player, media center (other than with Windows XP Media Center Edition and its successors), electronic billboard or other digital signage, Internet appliance or other Internet-connected device, PDA, medical device, ATM, telematic device, gaming machine, home automation system, kiosk, remote control device, or any other consumer electronics device, (b) operator-based mobile, cable, satellite, or television system or (c) other closed system device. For information on licensing Adobe Runtimes for use on such systems please visit http://www.adobe.com/go/licensing. You will notice, for its embedded operating systems, Microsoft buys and includes a fully paid license for Adobe.   Do you get this with Linux?  Unix?  QNX? So, what is 'open'?

  • Troubleshooting Oracle Java 7 with Firefox

    - by Sampo Smolander
    I run Ubuntu 13.04 with up-to-date Firefox and Oracle Java 7 is installed from the package oracle-java7-installer from the ppa:webupd8team/java PPA. Java doesn't work in Firefox. When I start firefox from the command line, and open a webpage with some java, the java applet doesn't work and in the terminal firefox prints: $ firefox (process:28565): GLib-CRITICAL **: g_slice_set_config: assertion `sys_page_size == 0' failed java.io.IOException: Cannot run program "/usr/lib/jvm/java-7-oracle/jre/bin/java": error=13, Permission denied at java.lang.ProcessBuilder.start(ProcessBuilder.java:1041) at sun.plugin2.jvm.JVMLauncher.start(Unknown Source) at sun.plugin2.main.server.JVMInstance.startImpl(Unknown Source) (and some 20-30 lines more) (I guess the GLib-line can be ignored here.) Also, when I close the tab that contained the java applet, firefox freezes and I have to kill it. However, the permissions look fine: $ ls -l /usr/lib/jvm/java-7-oracle/jre/bin/java -rwxr-xr-x 1 root root 5746 Jul 22 17:35 /usr/lib/jvm/java-7-oracle/jre/bin/java So, what could be wrong here? What to check next? EDIT: Oracle Java is needed for stupid Danske Bank online banking. (You are of course welcome to suggest me to change my bank.)
