  • how to get the update manager window visible?

    - by Max Waterman
    I can see from the launcher that the Update Manager is running - it has the little triangle by it. However, I am having trouble seeing the window. If I click on it from one desktop, it switches to another, so I assume that the Update Manager has its window on that other desktop, but it still doesn't show anything. If I click alt-tab to switch between apps, I can see that the Update Manager is there, but selecting it just shows me a blank screen. Also, when I select it, while still holding the alt-key, I see the top menu bar switch to 'Update Manager', but when I release alt, it changes back to Ubuntu Desktop. It's almost like the app is off the screen somewhere, perhaps with just a single pixel showing or something like that. disclaimer: One thing that might be affecting things is that I have 'focus follows mouse' configured, which makes things a bit funky with the menu not being on the window, where it should be (perhaps there's a way to put it back with the window?) - I like to be able to type into background windows, and manually control which window is in the foreground.

  • The tale of how the PowerShell CmdLets got installed with Azure SDK 1.4

    - by Enrique Lima
    I installed the Azure SDK 1.4 while rebuilding my laptop and ran the installation for the Windows Azure Service Management PowerShell CmdLets. Kicked off the installation script for the WASM PowerShell CmdLets by locating the path to which WASM PowerShell CmdLets was deployed to. Double clicked the startHere command. It will then open the WASM installation dialog. Click Next. Click Next. Notice the red x next to the Azure SDK 1.3, the problem is I have SDK 1.4 Here is the workaround, I go back to the location of the deployed WASM sources. Go into the setup path, then scripts>dependencies>check. Now, locate the CheckAzureSDK.ps1 file, and right-click, then edit. This is the content in the ps1 file, it check for the specific version of the Azure SDK, in this case, it is looking for version 1.3.11133.0038. We need for it to check for version 1.4.20227.1419 Now, save your ps1 file, go back to the open WASM install dialog, and click rescan. This time it should pass, then click next. A Command prompt window will appear, click any key. This completes the installation, click Close.

  • How do references work in R?

    - by djechlin
    I'm finding R confusing because it has such a different notion of reference than I am used to in languages like C, Java, Javascript... Ruby, Python, C++, well, pretty much any language I have ever programmed in ever. So one thing I've noticed is variable names are not irrelevant when passing them to something else. The reference can be part of the data. e.g. per this tutorial a <- factor(c("A","A","B","A","B","B","C","A","C")) results <- table(a) Leads to $a showing up as an attribute as $dimnames$a. We've also witnessed that calling a function like a <- foo(alpha=1, beta=2) can create attributes in a of names alpha and beta, or it can assign or otherwise compute on 1 and 2 to properties already existing. (Not that there's a computer science distinction here - it just doesn't really happen in something like Javascript, unless you want to emulate it by passing in the object and use key=value there.) Functions like names(...) return lvalues that will affect the input of them. And the one that most got me is this. x <- c(3, 5, 1, 10, 12, 6) y = x[x <= 5] x[y] <- 0 is different from x <- c(3, 5, 1, 10, 12, 6) x[x <= 5] <- 0 Color me confused. Is there a consistent theory for what's going on here?

  • How can I find which "command" corresponds to opening a gnome-panel menu, for use in a keyboard shortcut?

    - by Ryan Jendoubi
    There are many questions and answers here and around the web on setting basic keyboard shortcuts in GNOME. Most of them are either for launching applications, or Compiz settings, or for changing defaults for other things for which Ubuntu provides defaults shortcuts. What I want to know though is how to refer to a gnome-panel menu item in a custom keyboard shortcut. I'm using Ubuntu 11.10 with GNOME Classic, and the old GNOME 2 / Ubuntu 10.04 keyboard shortcuts for the main menus (Alt-F1) and the "Me Menu" (Super+S) don't seem to work. So my question is two-fold. Primarily I'd like to know how to set those shortcuts. But a second-order question is how I could have found this out myself: is there some program I can use to see what signals or commands are fired off when I click on various things, in this case gnome-panel menu items? I'm interested in the broader question because I've sometimes wanted to set shortcuts for specific menus or menu items in GNOME 2, so a way to find out what command I need there would be useful. Give a man a rod, as they say :-) I've had a look at a good lot of keyboard shortcut and menu related items here to no avail. One somewhat relevant question is this one, but it's just a "how do I do it" question, and applies to Unity, not GNOME, although it would be great if whatever investigatory method answers this question might also apply under different desktops, like Unity. The answer to this question is essentially how I was doing it in 10.04 / GNOME 2, although the questioner's query isn't exactly addressed - how to get directly to "Broadcast" with a key combination. Again, it would be great if an answer delving into how such menus work and how they interact with the rest of the system would be applicable to pinpoint menu items.

  • Laptop changes closing lid power options based on media/music playing

    - by Backdraft
    Hi, This is on a Lenovo X60 running Windows 7 Professional. This is just a pet peeve of mine, but I was wondering if it were somehow possible to have my laptop autodetect whether any media/music is playing on and change/switch the "Close lid" options under Power Options, ie. when something is playing change state to "Do Nothing" otherwise change state to "Sleep". I guess I can probably set a some key combo up with AutoHotKey to do it, but was hoping Windows could detect and switch my Power Options automatically. Thanks.

  • Purpose of JBoss tables

    - by Rich
    Hi Can anyone point me in the direction of some documentation (or provide the information here) about the following tables, created by JBoss 5.1.0 when it starts up? I know what they are for at a high level, and know why they are there, but I could do with some lower-level documentation about each table's purpose. The tables are: hilosequences timers jbm_counter jbm_dual jbm_id_cache jbm_msg jbm_msg_ref jbm_postoffice jbm_role jbm_tx jbm_user I know that the first two are associated with uuid-key-generator and the EJB Timer Service respectively, while the rest are associated with JBoss Messaging. What I want to know is something along the lines of "jmg_msg stores each message when it is created...", that kind of thing. I wasn't sure where to ask this question, ServerFault or StackOverflow, but I decided it wasn't programming related so thought I should put it here - I hope that's ok! Thanks Rich

  • How to properly backup mediawiki database (mysql) without messing up the data?

    - by Toto
    I want to backup a mediawiki database stored in a MySQL server 5.1.36 using mysqldump. Most of the wiki articles are written in spanish and a don't want to mess up with it by creating the dump with the wrong character set. mysql> status -------------- ...

  • Choosing Truecrypt volume names and keyfile names

    - by Howiecamp
    Any recommendations on what to name Truecrypt volumes (container files) and where to locate them? Certainly a name like "this is a truecrypt volume.tc" isn't a good idea. Any recommended storage locations? Same question for keyfiles that are generated with Truecrypt. Finally, lets say you choose an existing file, ymca.mp3, as your keyfile. Given that that file is innocuous and normal looking, isn't it easy to forget that's your key file so when you get sick of the Village People and delete the song you're hosed?

  • How to Manage and Use LVM (Logical Volume Management) in Ubuntu

    - by Justin Garrison
    In our previous article we told you what LVM is and what you may want to use it for, and today we are going to walk you through some of the key management tools of LVM so you will be confident when setting up or expanding your installation. As stated before, LVM is a abstraction layer between your operating system and physical hard drives. What that means is your physical hard drives and partitions are no longer tied to the hard drives and partitions they reside on.

  • Intermediate SSL Certificates on Azure Websites

    - by amhed
    I have successfully configured an Extended-Validation Certificate on an Azure Website following this article: http://www.windowsazure.com/en-us/documentation/articles/web-sites-configure-ssl-certificate/ The main (non-technical) stakeholder of the web application went through great lengths to validate that our site is secure. He went to this site to check the validity of our SSL: http://www.whynopadlock.com/ The site throw the following error: `SSL verification issue (Possibly mis-matched URL or bad intermediate cert.). Details: ERROR: no certificate subject alternative name matches`` The certificate is installed using IP Based SSL instead of SNI. This is done this way because some site visitors still use Internet Explorer 8 on Windows XP, which has no support for SNI and throws a security warning. Is my certificate correclty installed? I received three .CRT files from my SSL provider: PrimaryIntermediate.crt SecondaryIntermediate.crt EndCertificate.crt This is how I exported our certificate as a .PFX file to Azure: openssl pkcs12 -export -out myserver.pfx -inkey myserver.key -in myserver.crt

  • My internet connection slows or dies unexpectedly

    - by genesis
    I installed Ubuntu 10.04 once again and I'm having some problems which I had before, but I have no idea how I solved them. On Windows, everything's working fine and I had no problems with this. My problem is that sometimes, when browsing through the internet, webpages just start to load really slow, sometimes it doesn't load anything at all (Error 118 (net::ERR_CONNECTION_TIMED_OUT): The operation timed out.) and it starts to work after few minutes. My IPv4 settings are automatic (DHCP), and IPv6 settings are Ignored/Disabled. I think my previous problems had something to do with IPv6, but I'm not sure. Is there a fix for this? iwconfig lo no wireless extensions. eth0 no wireless extensions. wlan0 IEEE 802.11bgn ESSID:"Fsite1" Mode:Managed Frequency:2.442 GHz Access Point: C8:3A:35:40:43:68 Bit Rate=0 kb/s Tx-Power=20 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:on Link Quality=43/70 Signal level=-67 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0

  • How to efficiently protect part of an application with a license

    - by Patrick
    I am working on an application that has many functional parts. When a customer buys the application, he buys the standard functionality, but he can also buy some additional elements of the application for an additional price. All of the elements are part of the same application executable. A license key is used to indicate which of the elements should be accessible in the application. Some of the elements can be easily disabled if the user didn't pay for it. These are typically the modules that you can access via the application's menu. However, some elements give more problems: What if a part of the data model is related to an optional part? Do I build up these data structures in my application so the rest of my application can just assume they're always there? Or do I don't build them, and add checks in the rest of may application? What if some optional part is still useful to perform some internal tasks, but I don't want to expose it to the user externally? What if the marketing responsible wants to make a standard part now an optional part? In all of my application I assume that that part is present, but if it becomes optional, I should add checks on it everywhere in the application. I have some ideas on how to solve some of the problems (e.g. interfaces with dual implementations: one working implementation, and one that is activated if the optional part is not activated). Do you know of any patterns that can be used to solve this kind of problem? Or do you have any suggestions on how to handle this licensing problem? Thanks.

  • Microsoft secure downloader not finishing download

    - by Goran_Mandic
    I am downloading Windows 8 RTM using Microsoft's secure downloader provided by my school's DreamSpark account. The OS I'm currently on is Windows 8 preview. Once the download reaches 100%, it restarts to 0%. I open the download path folder, and find the en_windows_8_x64_dvd_915440.sdc file and the en_windows_8_x64_dvd_915440.scd.log file. The log file contains only one line : "Unpacking File: C:\Users\en_windows_8_x64_dvd_915440.sdc" I was unable to unpack the file using 3rd party software, and there seems to be no official software made for unpacking this type of file. What can I do to avoid downloading the OS illegally, even though I have my own product key?

  • Herding Cats - That's My Job....

    - by user709270
    Written by Mike Schmitz - Sr. Director, Program Management Oracle JD Edwards  I remember seeing a super bowl commercial several years ago showing some well dressed people on the African savanna herding cats. I remember turning to the people I was watching the game with and telling them, “You just watched my job description”. Releasing software is a multi-facetted undertaking. In addition to making sure the code changes are complete, you also need to make sure the other key parts of a release are ready. For example when you have a question about the software, will the person on the other end of the phone be ready to answer your question? If you need training on that cool new piece of functionality, will there be an online training course ready for you to review? If you want to read about how the software is supposed to function, is there a user manual available? Putting all the release pieces together so they are available at the same time is what the JD Edwards Program Management team does. It is my team’s job to work with all the different functional teams so when a release is made generally available you have all the things you need to be successful. The JD Edwards Program Management team uses an internal planning tool called the Release Process Model (RPM) to ensure all deliverables are accounted for in a release. The RPM makes sure all the release deliverables are ready at the correct time and in the correct format. The RPM really helps all the functional teams in JD Edwards know what release deliverables they are accountable for and when they are to be delivered. It is my team’s job to make sure everyone understands what they need to do and when they need to deliver. We then make sure they are all on track to deliver on-time and in the right format. It is just that some days this feels like herding cats.

  • Best way to go for simple online multi-player games?

    - by Mr_CryptoPrime
    I want to create a trivia game for my website. The graphic design does not have to be too fancy, probably no more advanced than a typical flash game. It needs to be secure because I want users to be able to play for real money. It also needs to run fast so users don't spend their time frustrated with game freezing. Compatibility, as with almost all online products, is key because of the large target market. I am most acquainted with Java programming, but I don't want to do it in Java if there is something much better. I am assuming I will have to utilize a variety of different languages in order for everything to come together. If someone could point out the main structure of everything so I could get a good start that would be great! 1) Language choice for simple secure online multiplayer games? 2) Perhaps use a database like MySQL, stored on a secure server for the trivia questions? 3) Free educational resources and even simpler projects to practice? Any ideas or suggestions would be helpful...Thanks!

  • Sound does not play when locking WinXP

    - by Christopher
    If I press the Windows-L combination to lock my PC the "Windows Logoff" sound does not play. It used to but at some point it stopped. I installed only trustworthy apps on my system and it is pretty clean so I don't think it is a virus. I checked the sounds in the control panel and "Windows Logoff" is set. Is there a sound associated with the key combination? Perhaps something in the registry? Any help is appreciated.

  • Worthless Anti-Spam (What can we learn)

    - by smehaffie
    I recently can across a site that had a “anti-spam” field at the bottom of the entry from.  The first issue I had with it was that at 1280X800 you could not read the value you were suppose to enter (see below).  You tell me, should you enter div, dlv, piv, or plv. But even worse than not being readable at high resolutions is the fact that the programmer who coded it really did not understand what this was used for.  An anti-spam (aka: catpcha) entry field should not be able to be read by looking at the HTML DOM object (so entry of value cannot be scripted).  In this case the value is simply a disabled text input filed that has the value you need to type.  So a hacker would simply need to search for text input field named “spam2” and then they could flood the site with spam. 1: <td> 2: <label> 3: <input name="spam1" type="text" class="small" id="spam1" size="6" maxlength="3" /> 4: <input name="spam2" type="text" class="small" id="spam2" value="plv" 5: disabled="disabled" size="6" maxlength="3" /> 6: * <span class="small">- Anti-SPAM key - please enter matching value</span> 7: </label> 8: </td>   There are some things to learn from this example: 1) Always make sure you understand why you are coding a feature/function for any program you write.  Just following the requirements without realizing the “why” will sooner or later come back to bite you.  I think the above example appears to be an example of this. 2) Always check how the screen appears in different resolutions.  In this case it was pretty much unreadable in 1280x800, but you could read it in 800X600 (but most people I know do not have their resolution set that low).  Lucky for me I could “View Source” and get the value I needed to enter.

  • Two Cloudy Observations from Oracle OpenWorld

    - by GeneEun
    Now that the dust has settled from another amazing Oracle OpenWorld, I wanted to reflect back on a couple of key observations I made during the event. First, it was pretty clear that Cloud was again a big deal at this year's conference. Yes, the Oracle Database 12c announcement was also huge, but for most it was hard to not notice that Oracle continues to be "all-in" with respect to cloud computing. Just to give you an idea of the emphasis on Cloud, there were over 300 Cloud-related sessions at this year's OpenWorld. If you caught some of the demo booths in the Oracle Red Lounge, then you saw some of the great platform, application, and social services that are now part of Oracle Cloud, as well as numerous demos of private cloud products that Oracle offers. Second, during Thomas Kurian's keynote presentation on Oracle Cloud, he announced the Preview Availability of a new service called Oracle Developer Cloud Service. This new platform service will provide developers with instant access to environments to better manage the application development lifecycle in the cloud. It provides development project teams access to favorite tools like Hudson, Git, Github, wikis, and tasks to help make innovation faster, more collaborative, and more effective. There's also integration with IDEs like Eclipse, NetBeans, and JDeveloper. If you're a developer, it's an awesome addition to Oracle Cloud's platform services!

  • Windows 8 and Cisco AnyConnect client issue

    - by Enrique Lima
    As many of us are doing these days, I have fully moved to Windows 8 on my PCs (laptops and desktops).  And in my role as a consultant I work with many clients, many of them use different vpn technologies.  While pretty much every single vpn client I had installed needed a trick or two to work, well Cisco’s AnyConnect vpn client had some issues.  Installation went well, no problem there.  The problem appeared when I attempted to connect, as I received the following message: Pretty clear what the issue is, right? right??!!?? Doing a bit of research (Google knows!), I cam across the following fix: Using our new favorite shortcut:  Windows Key + X Then Run > regedit. We then Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\vpnva From the image you can tell there are additional characters in the DisplayName that interfere with the device being able to be correctly identified. This is what it looks like originally. We will remove those characters so it looks more like: Close all open windows and attempt your connection.

  • Can't figure out how to make Slitaz USB persistent

    - by Dennis Hodapp
    I installed Slitaz on my USB. However I can't figure out how to make it persistent automatically. There are different sources telling me different ways to make it persistent. One told me to add "slitaz home=usb" to the syslinux.cfg file like this: append initrd=/boot/rootfs.gz rw root=/dev/null vga=normal autologin slitaz home=usb but it didn't work for me. http://www.slitaz.org/en/doc/handbook/liveusb.html gave an example of how to do it manually but I didn't try it and I also want it to happen automatically. custompc.co.uk/features/602451/make-any-pc-your-own-with-linux-on-a-usb-key.html is an older article that also explains how to make the USB persistent but I don't want to try it cause it looks outdated (from 2008) does anyone know the best way to make the USB automatically persistent?

  • How can I prevent users from installing software?

    - by Cypher
    Our organization is a bit different than most. During certain times of the year, we grow to thousands of employees, and during off-times, less than a hundred. Over the course of a few years, many thousands of people have come and gone in our offices, and left their legacy behind in the form of all sorts of unwanted, unapproved, (and sometimes unlicensed) software installs on our desktops. We are currently installing redundant domain controllers and upgrading current servers, all running Windows Server 2008 Enterprise, and will eventually be able to run a pure 2008 DC network. With that in mind, what are our options in being able to lock down users, such that they cannot install unauthorized software on systems without the assistance (or authorization) of the IT group? We need to support approximately 400 desktops, so automation is key. I've taken note of the Software Restrictions we can implement via Group Policy, but that implies that we already know what users will be installing and attempting to run... not quite so elegant. Any ideas?

  • Uninstalled Ubuntu, no GRLDR?

    - by user32965
    So I'm a big fat idiot. I installed Ubuntu 11.04 on my school's laptop, and here's come the time that I have to turn it back in. I wrote GRUB to the Master Boot Record, thinking it wasn't going to be permanent. So, fast forward to yesterday. I decided to hell with this, and popped in my Windows 7 CD, deleted the whole partition, formatted to NTFS, and installed Windows 7 on it. I'm surfing the web and my computer overheats [totally typical] I boot up, and get this: Try (hd0,0): FAT32: No GRLDR Try (hd0,1): invalid or null Try (hd0,2): invalid or null Try (hd0,3): invalid or null Try (hd1,0): NTFS5: No grldr Try (hd1,1): invalid or null Try (hd1,2): invalid or null Try (hd1,3): invalid or null Cannot find GRLDR. Press space bar to hold the screen, any other key to boot previous MBR... Timeout: 5 The timeout part just counts down to 0 from 5. I need to turn in this thing before tomorrow, please please please can someone help me out?

  • Ubuntu hang, and cannot be soft-reset after resuming from stand by mode

    I have downgrade my xorg drivers, so I can hibernate and stand by my ubuntu smoothly. However, in some case, there's a problem. My ubuntu get hang. When I tried to switch to console mode (Ctrl+Alt+F1), then I cannot login. The system always reply with an error whenever I tried to press a key. When I press Ctrl+Alt+Del to perform a softreset, here what's it said: [80141.320122] end_request: I/O error, dev sda, sector 193687181 init: control-alt-delete main process (5660) terminated with status 2. This error is not even recorded in syslog. I guess this should be a problem with my hard disk since it said something about a bad sector. Exactly, what kind of error is this?
