I have a used DelL latitude 2120 laptop with Ubuntu o/s I do not have administrator password and can not get past the screen that says this computer is protected by password authentication system?
I'm working on a Ubuntu system, and my client has completely forgotten his administrative password. He doesn't even remember entering one; however it is there.  I've tried the suggestions on the website, and I have been unsuccessful in deleting the password so that I can download applets required for running some files. Is there a solution?
List extending strange behaviour How can I disable a tab inside a TabControl? Is there a way to disable a tab in a ? I'm using Rules 7.x-2.6 and the way it works has changed a bit since I last saw.  I have a rule as follows:  EVENT A node has been flagged, under "Report content"  CONDITIONS None  ACTIONS Send mail to [site:mail]   However, I'd like to, instead of sending directly to [site:mail], send an email to all users flagged with an "admin" role.   Now I know that I'll need to provide a loop do so, but my sticking point is generating the list of users to pass to the loop. So far, I have attempted to add a new action:   "Fetch entity by property" Entity type: User Property: User roles Value: admin   But this doesn't seem to give me what I want in data selection, when passing it to the loop. Can someone recommend what they would set here? How do I start Nautilus as root? For a book cover, I want to write the title vertically (like in Japanese, but using English text):           T T        I H        T I  I  M  L S  S  Y  E   How do I do this without jumping through a host of \vbox and \hboxes? How do I change the MAC address of my network card? I have a local network in a Windows system where the Admin gives permission to the PCs by their MAC address. But he is on vacations and I have a new PC.  How can I change the MAC address of my new PC to have the same MAC address as the old one?  I know this can be used for spoofing the address, but this is local, so I don't think I will have a problem. Are the units of the quotient ring $\mathbb{F}_2[x]/\langle x^k+1 \rangle$ known in general, where $\mathbb{F}_2$ is the finite field with two elements? I'm specifically interested in the case where $k$ is divisible by two, such as say $k=8$, or $k=12$.  If so, can they be constructed easily? I'd be grateful if you could provide a few examples. How do I run an application with arguments from the command line without losing the terminal? I use dwm as a window manager on Ubuntu, I like tiled windows and I like them as few as possible. I sometimes need to run an application (let's say it's the pdf viewer mupdf in x11) from the terminal, the application will be launched in a new window but the terminal from which I launched becomes this prompt-less console for that application to log whatever.  I use dmenu to launch applications, but sometimes an application needs arguments (file names) to start. I use uxrvt within x11 managed by dwm. How do I secure my house against intruders? What are some suggestions for securing your house from an intruder? Right now we have a GE Simon XT alarm system, but it doesn't cover breaking a window. We put some PVC pipes in the tracks of the lower floor windows as well. What other suggestions do you have?  EDIT: I also would like to know what structural changes I should be looking at. A simple one is to ensure that the deadbolt goes into a stud (they don't always!). Any other suggestions like this would be great. Aiming at specific body parts My players have been asking to improvise specific combat actions, mostly the archer wanting to aim at specific body parts. I haven't been able to find anything in the DMG or the PHB on the subject so I was wondering how I should deal with this.    How (if at all) should an attack roll be modified when targeting a specific body part? If there is not RAW on this I am open to playtested house rules per . Tempdb Add files require Restart Does adding Tempdb files require a restart? We would like to Add files on the same drive, Not Delete and Not modify. We tested in Dev and QA environment, restart was not required. However for production I would like to be sure everything works properly. Some are stating conditions, not always necessary, sometimes necessary, I am reading resources below:  ALTER DATABASE [tempdb] ADD FILE ( NAME = N'tempdev2', FILENAME = N'G:\tempdb2.ndf' , SIZE = 12288000KB , MAXSIZE = UNLIMITED, FILEGROWTH = 0 ) GO ALTER DATABASE [tempdb] ADD FILE ( NAME = N'tempdev3', FILENAME = N'G:\tempdb3.ndf' , SIZE = 12288000KB , MAXSIZE = UNLIMITED, FILEGROWTH = 0    Do You Need an Outage to Add tempdb files? Brent Ozar  "Technically, not always. But practically speaking, yes. If you have to shrink files, that’s very difficult while SQL Server is in use, and we’ve seen cases where anti-virus/file control tools didn’t act up until SQL Server was restarted after the files were added."   "Once the additional files have been created, it’s not always necessary to perform a service restart.  However, in many production environments, simply modifying the filesize of the existing TempDB datafile (tempdev) is not possible without restarting services first. "  The following resources are saying no restart required: Best practices for making a WordPress site "movable"? I'm planning to buy a domain and install a WordPress site on it at a web-hosting company.  But first I'll need to iron-out some bugs...  I got a working LAMP-stack at my home-computer, so I'm thinking about first installing my site locally - off the Internet.  I'll be mostly tweaking and making "test-posts" to check that everything works, but I'll probably also make some posts I'd like to keep when I move the site and take it online.  When I'm done chasing bugs; I guess I'll just package the public_html|www directory-tree and upload it to the web-hosting company, and also export the database from my home-computer to the web-hosting.    What I'm wondering if there are some "best practices", some do-s and don't-s, some major pits to take note of?    For example, how can ensure the smooth transition of domain-name in posts and links as such, from localhost to whatever-i-end-up-buying.com (I know from previous attempt of running WordPress at my home computer, that this didn't always work quite well...). Using recordtypes of the same name across multiple SObject types I have one recordtype named 'India' in both Account and Contact Objects.My requirement is whenever i create a new account record of type 'India' a new contact record of type 'India' should be created automatically.  i tried with the following code:  trigger AccRecTypeTrigger on Account (before insert) {     List&lt;RecordType&gt; recType = [select id,name from RecordType where sobjectType = 'Account' and isActive = true];    Map&lt;String,Id&gt; m = new Map&lt;String,Id&gt;();    for(RecordType r : recType){      m.put(r.name,r.id);    }     List&lt;Contact&gt; conlst = new List&lt;Contact&gt;();    for(Account a : trigger.new){        a.recordTypeId = m.get('India');        Contact con = new Contact();        con.accountId = a.id;        con.recordTypeId = a.recordTypeId;        con.recordType.name = a.recordType.name;         conlst.add(con);       }    insert conlst; }   But i am getting following error when i try to save     Apex trigger AccRecTypeTrigger caused an unexpected exception, contact   your administrator: AccRecTypeTrigger: execution of BeforeInsert   caused by: System.NullPointerException: Attempt to de-reference a null   object: Trigger.AccRecTypeTrigger: line 14, column 1   Please help me how to achieve this...... Obfuscation is one way, but it can't protect from breaking the piracy protection security of the application. How do I make sure that the application is not tampered with, and how do I make sure that the registration mechanism can't be reverse engineered?  Also it is possible to convert a C# application to native code, and  is too costly.  C# provides lot of features, and is the ideal language for my code, so writing the whole codebase again in C++ is out of the question.  Secure certificates can be easily removed from the signed assemblies in .NET. Cannot install a version of GDAL via Anaconda that permits reading BigTIFFs I recently ordered the GTA V PC from Steam and when I finished installing and launch the game. It gave me "Grand Theft Auto V has exited unexpectedly". I tried "safe mod" and every option available, but none of them work. I checked some forums and found a lot of people having the same problems. What could be the possible cause? I'm using a laptop with these specs:  CPU: i7 4700m GPU: AMD HD8970M RAM: 8GB  I'm pretty sure my laptop is way beyond the minimum specs. Does someone know how can I enter the game? A library to convert ANSI escapes (terminal formatting/color codes) to HTML I'm looking for a code library that converts ANSI escape sequences into HTML color, via plain  tags or CSS. For example, something that would convert this:  ESC[00mESC[01;34mbinESC[00m ESC[01;34mcodeESC[00m ESC[01;31mdropbox-lnx.x86-0.6.404.tar.gzESC[00m ESC[00mfooESC[00m  Into this:  &lt;span style="color:blue"&gt;bin&lt;/span&gt; &lt;span style="color:blue"&gt;code&lt;/span&gt; &lt;span style="color:red"&gt;dropbox-lnx.x86-0.6.404.tar.gz&lt;/span&gt; foo   Converting breaks into &lt;br/&gt; isn't necessary, it's just the escape codes that I don't know. I could hack it together myself, but I'd probably miss something important like underlines or mess up how background colors work. I'd rather just sit on top of someone else's code.  Does such a tool (command line linux) or library (perl, python, or ruby preferably) exist? "Requires 50 reputation" to comment on deleted posts So I recently saw add comment (requires 50 reputation) on a deleted answer. After looking around a bit, it seems to be on all deleted posts now (only deleted posts, normal posts still say just add comment).  I'm sure it wasn't there before (I think it just said add comment (unclickable) or possible nothing).  It is also on , presumably the root cause is the same.  And yes, I do have more than 50 reputation (in case anyone was wondering).  Just to clarify, requires 50 reputation obviously shouldn't be there for users with 50 or more reputation. Choices:   Display nothing Unclickable add comment - probably not ideal Unclickable add comment (disabled for deleted posts) or something along those lines   FYI - You may be somewhat confused right about now if you can't  yet. Permanently remove/disable Touch Keyboard in Windows 8 taskbar? These are my current disk partitions. /yedek is for some personal backup files. As you can see there is only Ubuntu on my PC. I will install Windows, too. Because of this I want to shrink /dev/sda3 . It currently 546GB and I want to split it: 300GB for / and 246GB for Windows (NTFS) is OK for me.  I'm using GParted for the first time. How can I shrink /?  I don't want to lose any datas from Ubuntu.
