  • How to mount an external Soundcard during startup?

    - by Moe
    I have an external sound card (Soundblaster XFi HD) connected to my Ubuntu 12.04 32-bit. that won't show up automatically after booting. After each boot process I need to plug the card out of the USB port and reconnect it, then it is found by the system and automatically used. I would like to either have it connected automatically during the boot process or at least have a little script or something which I can use after booting so that I don't have to manually plug the device off and on. Please note that I'm a total noob. If you don't mind please tell me the procedure step by step. Also, if I need to get some information via the terminal I'd need to be told the precise command to get it.

  • Change the Default Number of Rows of Tiles on the Windows 8 UI (Metro) Screen

    - by Lori Kaufman
    By default, Windows 8 automatically sets the number of rows of tiles to fit your screen, depending on your monitor size and resolution. However, you can tell Windows 8 to display a certain number of rows of tiles at all times, despite the screen resolution. To do this, we will make a change to the registry. If you are not already on the Desktop, click the Desktop tile on the Start screen. NOTE: Before making changes to the registry, be sure you back it up. We also recommend creating a restore point you can use to restore your system if something goes wrong. HTG Explains: Why Do Hard Drives Show the Wrong Capacity in Windows?

  • finding the gedit plugin folder

    - by BlackSheep
    I am a bit confused as to where I should put externally downloaded plugins. I have tried putting them in: /usr/share/gedit/plugins ~/.local/gedit/plugins ~/.gnome2/gedit/plugins /usr/lib/gedit/plugins The way I have checked whether the plugins show up or not is going to Edit-Preferences-Plugins and looking for the ones I have downloaded (clickconfig, gedit-developer-plugins-...). Since I do not see any new plugins appearing, I have to assume that I am doing something wrong. None of these have worked. I am a bit tired of polluting my system. It's probably my own fault as it's written somewhere I have not thought to look. Please let me know how to add external plugins to gedit properly. I am running Ubuntu 11.10. My gedit version is 3.2.3 EDIT: I am still not able to solve this problem. I have tried the following folder now as well, and it hasn't worked: ~/.config/gedit/plugins

  • Center Pictures and Other Objects in Office 2007 & 2010

    - by Matthew Guay
    Sometimes it can be difficult to center a picture in a document just by dragging it dragging it around. Today we show you how to center pictures, images, and other objects perfectly in Word and PowerPoint. Note: For this tutorial we’re using Office 2010, but the steps are nearly identical in 2007. Centering a Picture in Word First let’s insert a picture into our document.  Click the Insert tab, and then click Picture. Once you select the picture you want, it will be added to your document.  Usually, pictures are added wherever your curser was in the document, so in a blank document it will be added at the top left. Also notice Picture Tools show up in the Ribbon after inserting an image. Note: The following menu items are available in Picture Tools Format tab which is displayed when you select the object or image you’re working with. How do we align the picture just like we want?  Click Position to get some quick placement options, including centered in the middle of the document or on the top.    However, for more advanced placement, we can use the Align tool.  If Word isn’t maximized, you may only see the icon without the “Align” label. Notice the tools were grayed out in the menu by default.  To be able to change the Alignment, we need to first change the text wrap settings. Click the Wrap Text button, and any option other than “In Line with Text”.  Your choice will depend on the document you’re writing, just choose the option that works best in the document.   Now, select the Align tools again.  You can now position your image precisely with these options. Align Center will position your picture in the center of the page widthwise. Align Middle will put the picture in the middle of the page height-wise. This works the same with textboxes.  Simply click the Align button in the Format tab, and you can center it in the page. And if you’d like to align several objects together, simply select them all, click Group, and then select Group from the menu.   Now, in the align tools, you can center the whole group on your page for a heading, or whatever you want to use the pictures for. These steps also work the same with Office 2007. Center objects in PowerPoint This works similar in PowerPoint, except that pictures are automatically set for square wrapping automatically, so you don’t have to change anything.  Simply insert the picture or other object of your choice, click Align, and choose the option you want. Additionally, if one object is already aligned like you want, drag another object near it and you will see a Smart Guide to help you align or center the second object with the first.  This only works with shapes in PowerPoint 2010 beta, but will work with pictures, textboxes, and media in the final release this summer. Conclusion These are good methods for centering images and objects in Word and PowerPoint.  From designing perfect headers to emphasizing your message in a PowerPoint presentation, this is something we’ve found useful and hope you will too. Since we’re talking about Office here, it’s worth mentioning that Microsoft has announced the Technology Guarantee Program for Office 2010. Essentially what this means is, if you purchase a version of Office 2007 between March 5th and September 30th of this year, when Office 2010 is released you’ll be able to upgrade to it for free!

  • How can I login to lightdm with password for fingerprint-enabled user after 12.10 upgrade?

    - by jxn
    Sorry for the long question. I have a laptop with ubuntu quantal 12.10, a fingerprint scanner, and a few active user accounts. When the machine boots up to lightdm, I get a prompt toenter my password or scan my finger print. Every now and then, fingerprint scanning just doesn't seem to work. Before the 12.10 upgrade, I was always able to enter my password for this user when fingerprint failed. Now, no matter what, I have to scan my prints to login as this user. If I try to login as a different user (fingerprint is not enabled for any others), I can see the password is typed out -- asterisks show in the password input box as I type them -- and get in. Not so for the fingerprint user. Any clues on how to figure out what's gone wrong?

  • Why is Python slower than Java but faster than PHP

    - by good_computer
    I have many times seen various benchmarks that show how a bunch of languages perform on a given task. Always these benchmarks reveal that Python is slower then Java and faster than PHP. And I wonder why is that the case. Java, Python, and PHP run inside a virtual machine All three languages convert their programs into their custom byte codes that run on top of OS -- so none is running natively Both Java and Python can be "complied" (.pyc for Python) but the __main__ module for Python is not compiled Python and PHP are dynamically typed and Java statically -- is this the reason Java is faster, and if so, please explain how that affects speed. And, even if the dynamic-vs-static argument is correct, this does not explain why PHP is slower than Python -- because both are dynamic languages. You can see some benchmarks here and here, and here

  • Were you a good programmer when you first left university?

    - by dustyprogrammer
    I recently graduated, from university. I have since then joined a development team where I am by far the least experienced developer, with maybe with a couple work terms under my belt, meanwhile the rest of the team is rocking 5-10 years experience. I am/was a very good student and a pretty good programmer when it came to bottled assignments and tests. I have worked on some projects with success. But now I working with a much bigger code-base, and the learning curve is much higher... I was wondering how many other developers started out their careers in teams and left like they sucked. When does this change? How can I speed up the process? My seniors are helping me but I want to be great and show my value now. I don't to start a flame war, this is just a question I have been having and I was hoping to get some advice from other experienced developers, as well as other beginners like me.

  • Getting many files from a SharePoint Document Library the easy way

    - by Stacy Vicknair
    As an individual who does not use Internet Explorer as their primary browser, there is a great feature that you may never notice that allows you to easily copy files to and from a document library: the Open in Windows Explorer link. In browsers such as Chrome or Firefox this link may not appear. I know this isn’t a major groundbreaking feature, but it’s really easy to overlook and it’s worth knowing about, especially when you need to create a local copy of a full document library. In this quick blog we’ll go over how to access this feature in both SharePoint 2007 and 2010. First, make sure you are in Internet Explorer. These options may not show in other browsers. In SharePoint 2007, browse to the document library you would like to access then select Actions > Open with Windows Explorer. In SharePoint 2010, browse to the document library you would like to access then select Library Tools > Library > Open with Explorer from the ribbon.

  • Ubuntu Installation-Allocate drive space/Boot Loader

    - by user10134
    When I try to install ubuntu 10.10 from the official livedisc I got in the mail, when I get to the "Allocate Disk Space" step I cannot get it to work. I shrank my win7 partition so I have unallocated space, then I tried using the space while it is formatted in NTFS, but the partitions will not show up in the box. /dev/sda is selected under boot loader, and I can't select anything else, but the partition box is blank so when I click "install ubuntu" it just says: "No root file system is defined. Please correct this from the partitioning menu." -I am trying to dual-boot win7 and ubuntu, but I was never asked in the install process whether I would like to install just ubuntu or dual-boot?

  • Are CK Metrics still considered useful? Is there an open source tool to help?

    - by DeveloperDon
    Chidamber & Kemerer proposed several metrics for object oriented code. Among them, depth of inheritance tree, weighted number of methods, number of member functions, number of children, and coupling between objects. Using a base of code, they tried to correlated these metrics to the defect density and maintenance effort using covariant analysis. Are these metrics actionable in projects? Perhaps they can guide refactoring. For example weighted number of methods might show which God classes needed to be broken into more cohesive classes that address a single concern. Is there approach superseded by a better method, and is there a tool that can identify problem code, particularly in moderately large project being handed off to a new developer or team?

  • Macbook Pro 8,1 - wireless interface not showing up

    - by Florian Margaine
    I've installed Ubuntu 11.10 on my Macbook Pro 8,1. Everything went fine and everything installs fine except for the wireless interface. I've installed the b43 module according to these instructions: https://help.ubuntu.com/community/MacBookPro8-1/Natty#Wireless I've tried compiling the module, ndiswrapper and also the last solution mentioned using this PPA: ppa:zwaldowski/ppa. With the three solutions, the module loads finely. It works smoothly. lspci shows the wireless card without problem. But there is no wireless interface. iwconfig or ifconfig both show eth0 and lo as interfaces, but no eth1 or wlan0 interface is showing up. I have no idea why, and I'm completely stuck there.

  • WiFi not working on Dell Inspiron 1564

    - by Zack Warren
    hope you can offer some help! I'm new to Ubuntu (and Linux for that matter), but I managed to install Ubuntu 12.04 yesterday on an old Dell Inspiron 1564 Laptop. Everything works fine, with the exception of the wireless connection. Using my wired ethernet, I was able to look up several solutions which seemed as if they would work, but I've had no luck. Currently, wireless does show as enabled, but all wireless networks are disconnected, in fact, none of the networks are even listed (and I can see them on other devices in the home). Let me know what you need to help me! Thanks in advance!

  • Windows 8 Live Accounts and the actual Windows Account

    - by Rick Strahl
    As if Windows Security wasn't confusing enough, in Windows 8 we get thrown yet another curve ball with Windows Live accounts to logon. When I set up my Windows 8 machine I originally set it up with a 'real', non-live account that I always use on my Windows machines. I did this mainly so I have a matching account for resources around my home and intranet network so I could log on to network resources properly. At some point later I decided to set up Windows Live security just to see how changes things. Windows wants you to use Windows Live Windows 8 logins are required in order for the Windows RT account info to work. Not that I care - since installing Windows 8 I've maybe spent 10 minutes with Windows RT because - well it's pretty freaking sucky on the desktop. From shitty apps to mis-managed screen real estate I can't say that there's anything compelling there to date, but then I haven't looked that hard either. Anyway… I set up the Windows Live account to see if that changes things. It does - I do get all my live logins to work from Live Account so that Twitter and Facebook posts and pictures and calendars all show up on live tiles on the start screen and in the actual apps. That's nice-ish, but hardly that exciting given that all of the apps tied to those live tiles are average at best. And it would have been nice if all of this could be done without being forced into running with a Windows Live User Account - this all feels like strong-arming you into moving into Microsofts walled garden… and that's probably what it's meant to do. Who am I? The real problem to me though is that these Windows Live and raw Windows User accounts are a bit unpredictable especially when it comes to developer information about the account and which credentials to use. So for example Windows reports folder security like this: Notice it's showing my Windows Live account. Now if I go to Edit and try to add my Windows user account (rstrahl) it'll just automatically show up as the live account. On the other hand though the underlying system sees everything as my real Windows account. After I switched to a Windows Live login account and I have to login to Windows with my Live account, what do you suppose this returns?Console.WriteLine(Environment.UserName); It returns my raw Windows user account (rstrahl). All my permissions, all my actual settings and the desktop console altogether run under that account. If I look in TaskManager (or Process Explorer for me) I see: Everything running on the desktop shell with my login running under my Windows user account. I suppose it makes sense, but where is that association happening? When I switched to a Windows Live account, nowhere did I associate my real account with the Live account - it just happened. And looking through the account configuration dialogs I can't find any reference to the raw Windows account. Other than switching back I see no mention anywhere of the raw Windows account - everything refers to the Live account. Right then, clear as potato soup! So this is who you really are! The problem is that in some situations this schizophrenic account behavior gets a bit weird. Today I was running a local Web application in IIS that uses Windows Authentication - I tried to log-in with my real Windows account login because that's what I'm used to using with WINDOWS freaking Authentication through IIS. But… it failed. I checked my IIS settings, my apps login settings and I just could not for the life of me get into the site with my Windows username. That is until I finally realized that I should try using my Windows Live credentials instead. And that worked. So now in this Windows Authentication dialog I had to type in my Live ID and password, which is - just weird. Then in IIS if I look at a Trace page (or in my case my app's Status page) I see that the logged on account is - my Windows user account. What's really annoying about this is that in some places it uses the live account in other places it uses my Windows account. If I remote desktop into my Web server online - I have to use the local authentication dialog but I have to put in my real Windows credentials not the Live account. Oh yes, it's all so terribly intuitive and logical… So in summary, when you log on with a Live account you are actually mapped to an underlying Windows user. In any application if you check the user name it'll be the underlying user account (not sure what happens in a Windows RT app or even what mechanism is used there to get the user name info).  When logging on to local machine resource with user name and password you have to use your Live IDs even if the permissions on the resources are mapped to your underlying Windows account. Easy enough I suppose, but still not exactly intuitive behavior…© Rick Strahl, West Wind Technologies, 2005-2012Posted in Windows   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

  • Why don’t UI frameworks use generics?

    - by romkyns
    One way of looking at type safety is that it adds automatic tests all over your code that stop some things breaking in some ways. One of the tools that helps this in .NET is generics. However, both WinForms and WPF are generics-free. There is no ListBox<T> control, for example, which could only show items of the specified type. Such controls invariably operate on object instead. Why are generics and not popular with UI framework developers?

  • Can resizing images with css be good?

    - by Echo
    After reading Is CSS resizing of images still a bad idea?, I thought of a similar question. (too similar? should this be closed?) Lets say you need to use 10 different product image sizes throughout your website and you have 20k-30k different product images, should you use 10 different files for each image size? or maybe 5 different files and use css to resize the other 5? Would there ever be combination that would be good? Or should you always make separate image files? If you use css to resize them, you will save on storage (in GBs) but you will have slight increase in bandwidth and slower loading images(but if images are cached, and you show both sizes of the image would you use less bandwidth and have faster loads?) (But of course you wouldn't want to use css to resize images for mobile sites.)

  • Google shows subdomain of main site instead of add on domain URL

    - by Welsher
    I have my host (lunarpages) set up with a few add on domains to my main account. These show up as sub-domains of my main account, but they can be reached by using the new domain I've created. So: subdomain1.domain.com -- www.mynewsite.com subdomain2.domain.com -- www.myothersite.com etc. The problem is, mynewsite.com shows up in google with that domain, but myothersite.com shows up with subdomain2.domain.com. I don't have a clue what might be causing this to happen. If anyone has an advice or can point me in the right direction, I'd really appreciate it! Thanks.
