  • Windows 7/Ubuntu 10.10 Dual-Triple Boot Partitioning Recommendation for HP Laptop OEM

    - by Denja
    Hi Linux Community, I find my self struggling with the ever slow and buggy windows OS once again. It's Time for me to go with the Ubuntu/Linux way for a better and faster Operating System. As a Computer technician i want to learn and use both Systems but possibly introduce New users to more affordable Linux Based Systems. For now, Im in the process of creating dual-boot or even triple boot layouts on my laptop machine Here's the layout in use now: * (C:) Windows 7 system partition NTFS - 284,89GB (Primary,Boot,Pagefile,Dump) * HP_TOOLS system partition FAT32 - 99MB (Primary) * (D:) RECOVERY partition NTFS - 12,90GB (Primary) * SYSTEM partition NTFS 199MB (Primary) Here's the layout I want to make. * (C:) Windows 7 system partition NTFS - 60GB (Primary) (sda1) * (D:) Windows data partition (user files) NTFS - 60GB(Extended or Primary)(sda2);wanna share with Linux * Linux root Ext4 - 10GB (Primary)(sda3) * Linux swap swap- RAM size, 3GB (sda4) * Linux home Ext4- 164,9GB (Extended)(sda5) Question 1: Based on my layout what is your suggestion for a Triple Boot layout for an additional Linux OS (Like Puppy)? Thank you in advance for your advises and suggestions.

  • What Regex can strip e.g. "note:" and "firstName: " from the left of a string?

    - by Edward Tanguay
    I need to strip the "label" off the front of strings, e.g. note: this is a note needs to return: note and this is a note I've produced the following code example but am having trouble with the regexes. What code do I need in the two ???????? areas below so that I get the desired results shown in the comments? using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Text.RegularExpressions; namespace TestRegex8822 { class Program { static void Main(string[] args) { List<string> lines = new List<string>(); lines.Add("note: this is a note"); lines.Add("test: just a test"); lines.Add("test:\t\t\tjust a test"); lines.Add("firstName: Jim"); //"firstName" IS a label because it does NOT contain a space lines.Add("She said this to him: follow me."); //this is NOT a label since there is a space before the colon lines.Add("description: this is the first description"); lines.Add("description:this is the second description"); //no space after colon lines.Add("this is a line with no label"); foreach (var line in lines) { Console.WriteLine(StringHelpers.GetLabelFromLine(line)); Console.WriteLine(StringHelpers.StripLabelFromLine(line)); Console.WriteLine("--"); //note //this is a note //-- //test //just a test //-- //test //just a test //-- //firstName //Jim //-- // //She said this to him: follow me. //-- //description //this is the first description //-- //description //this is the first description //-- // //this is a line with no label //-- } Console.ReadLine(); } } public static class StringHelpers { public static string GetLabelFromLine(this string line) { string label = line.GetMatch(@"^?:(\s)"); //??????????????? if (!label.IsNullOrEmpty()) return label; else return ""; } public static string StripLabelFromLine(this string line) { return ...//??????????????? } public static bool IsNullOrEmpty(this string line) { return String.IsNullOrEmpty(line); } } public static class RegexHelpers { public static string GetMatch(this string text, string regex) { Match match = Regex.Match(text, regex); if (match.Success) { string theMatch = match.Groups[0].Value; return theMatch; } else { return null; } } } }

  • Collision Detection with SAT: False Collision for Diagonal Movement Towards Vertical Tile-Walls?

    - by Macks
    Edit: Problem solved! Big thanks to Jonathan who pointed me in the right direction. Sean describes the method I used in a different thread. Also big thanks to him! :) Here is how I solved my problem: If a collision is registered by my SAT-method, only fire the collision-event on my character if there are no neighbouring solid tiles in the direction of the returned minimum translation vector. I'm developing my first tile-based 2D-game with Javascript. To learn the basics, I decided to write my own "game engine". I have successfully implemented collision detection using the separating axis theorem, but I've run into a problem that I can't quite wrap my head around. If I press the [up] and [left] arrow-keys simultaneously, my character moves diagonally towards the upper left. If he hits a horizontal wall, he'll just keep moving in x-direction. The same goes for [up] and [left] as well as downward-diagonal movements, it works as intended: http://i.stack.imgur.com/aiZjI.png Diagonal movement works fine for horizontal walls, for both left and right-movement However: this does not work for vertical walls. Instead of keeping movement in y-direction, he'll just stop as soon as he "enters" a new tile on the y-axis. So for some reason SAT thinks my character is colliding vertically with tiles from vertical walls: http://i.stack.imgur.com/XBEKR.png My character stops because he thinks that he is colliding vertically with tiles from the wall on the right. This only occurs, when: Moving into top-right direction towards the right wall Moving into top-left direction towards the left wall Bottom-right and bottom-left movement work: the character keeps moving in y-direction as intended. Is this inherited from the way SAT works or is there a problem with my implementation? What can I do to solve my problem? Oh yeah, my character is displayed as a circle but he's actually a rectangular polygon for the collision detection. Thank you very much for your help.

  • What is better in WPF for UI layout, using one Grid, or nested Grids.

    - by Matthijs Wessels
    I am making a UI in WPF, I have a bunch of functional areas and I use a Grid to organize it. Now the Grid that I want is not uniform, as in, some functional area will span multiple cells in the Grid. I was wondering what the best practise is in solving this. Should I create one grid and then for each functional area set it to span multiple cells, or should I split it up into multiple nested Grids. In this image, the leftmost panel (panels separated by the gray bar) is what I want. The middle panel shows one grid where the blue lines are overlapped by a functional area. The rightmost panel shows how I could do it with nested grids. You can see the green grid has one horizontal split. In the bottom cell is the yellow Grid with a vertical split. In side the left cell is the red Grid with again a horizontal split. I was just wondering what is best practise, the middle or the right panel.

  • Where/When do C# and the .NET Framework fail to be the right tool?

    - by Nate Bross
    In my non-programming life, I always attempt to use the appropriate tool for the job, and I feel that I do the same in my programming life, but I find that I am choosing C# and .NET for almost everything. I'm finding it hard to come up with (realistic business) needs that cannot be met by .NET and C#. Obviously embedded systems might require something less bloated than the .NET Micro Framework, but I'm really looking for line of business type situations where .NET is not the best tool. I'm primarly a C# and .NET guy since its what I'm the most comfertable in, but I know a fair amount of C++, php, VB, PowerShell, batch files, and Java, as well as being versed in the web technologes (JavaScript, HTML, and CSS). But I'm open minded about it my skill set and I'm looking for cases where C# and .NET are not the right tool for the job. I choose .NET and C# because I'm comfortable with it, but I'm looking for cases where it isn't appropriate.

  • How do I get a right outer join in L2E?

    - by Dan
    I have two tables that I set up through the VS Entity Data Model Diagram tool. I'm trying to do a right outer join and it doesn't return results from the 2nd table. I have set up a 0..1 to MANY relationship from the diagram tool. When I run a Linq-To-Entities query, it still defaults to an INNER JOIN. From my understanding of entities, if I set up the relationship using VS, when I join the tables, it should automagically figure out the join syntax based on the relationship I supply. It doesn't seem to be doing that. I am using EF v1 (not Linq-to-Sql). Query I'm running: from s in SomeTable join t in SomeOtherTable on s.ID equals t.ID select new { s.MyFieldName, t.MyOtherFieldName }

  • jQuery slideable divs with floated images how to make the right size.

    - by Malachi
    I am relatively new to using jQuery and I have a problem with creating some sliding tabs to work with images that are floated inside. http://www.dur.ac.uk/malachi.soord/jin/ The above page demonstrates the problem I am facing - click on the about tab and you will notice that the image that is inside is floated to the right - which I know is not taken into consideration when jQuery is calculates the height of each div tab with: $("#content > div").each (function() { $(this).css("height", $(this).height()); }); Is there a work around which could be used to allow me to take this into consideration? or is there a better way to achieve what I am trying to achieving.

  • Returning a CSS element

    - by TMP
    Is there a way to return a CSS element? I was using Adobe Edge and adding some of my own code in their code tab, but in order to create boundaries I would need to keep track of margin-top or margin-left. The following code works to move the element "woo" but I'm not sure how to call the elements to add something like "|| sym.$("woo").css({"margin-left"0px"}) to the move left code. //Move RIGHT if (e.which == 39) { sym.$("woo").css({"margin-left":"+=10px"}); } //Move UP else if (e.which == 38) { sym.$("woo").css({"margin-top":"-=10px"}); } //Move Left else if (e.which == 37) { sym.$("woo").css({"margin-left":"-=10px"}); } //Move DOWN else if (e.which == 40) { sym.$("woo").css({"margin-top":"+=10px"}); } EDIT: I changed the Left if statement to the following: else if (e.which == 37 && ($("woo").css("margin-left")>0)) { It seems to be working to some extent except for now it won't move left at all! I tried doing <0 too in case I was screwing up a sign but it won't let me move the element left either.

  • Declaring pointers; asterisk on the left or right of the space between the type and name?

    - by GenTiradentes
    I've seen mixed versions of this in a lot of code. (This applies to C and C++, by the way.) People seem to declare pointers in one of two ways, and I have no idea which one is correct, of if it even matters. The first way it to put the asterisk adjacent the type name, like so: someType* somePtr; The second way is to put the asterisk adjacent the name of the variable, like so: someType *somePtr; This has been driving me nuts for some time now. Is there any standard way of declaring pointers? Does it even matter how pointers are declared? I've used both declarations before, and I know that the compiler doesn't care which way it is. However, the fact that I've seen pointers declared in two different ways leads me to believe that there's a reason behind it. I'm curious if either method is more readable or logical in some way that I'm missing.

  • Detecting walls or floors in pygame

    - by Serial
    I am trying to make bullets bounce of walls, but I can't figure out how to correctly do the collision detection. What I am currently doing is iterating through all the solid blocks and if the bullet hits the bottom, top or sides, its vector is adjusted accordingly. However, sometimes when I shoot, the bullet doesn't bounce, I think it's when I shoot at a border between two blocks. Here is the update method for my Bullet class: def update(self, dt): if self.can_bounce: #if the bullet hasnt bounced find its vector using the mousclick pos and player pos speed = -10. range = 200 distance = [self.mouse_x - self.player[0], self.mouse_y - self.player[1]] norm = math.sqrt(distance[0] ** 2 + distance[1] ** 2) direction = [distance[0] / norm, distance[1 ] / norm] bullet_vector = [direction[0] * speed, direction[1] * speed] self.dx = bullet_vector[0] self.dy = bullet_vector[1] #check each block for collision for block in self.game.solid_blocks: last = self.rect.copy() if self.rect.colliderect(block): topcheck = self.rect.top < block.rect.bottom and self.rect.top > block.rect.top bottomcheck = self.rect.bottom > block.rect.top and self.rect.bottom < block.rect.bottom rightcheck = self.rect.right > block.rect.left and self.rect.right < block.rect.right leftcheck = self.rect.left < block.rect.right and self.rect.left > block.rect.left each test tests if it hit the top bottom left or right side of the block its colliding with if self.can_bounce: if topcheck: self.rect = last self.dy *= -1 self.can_bounce = False print "top" if bottomcheck: self.rect = last self.dy *= -1 #Bottom check self.can_bounce = False print "bottom" if rightcheck: self.rect = last self.dx *= -1 #right check self.can_bounce = False print "right" if leftcheck: self.rect = last self.dx *= -1 #left check self.can_bounce = False print "left" else: # if it has already bounced and colliding again kill it self.kill() for enemy in self.game.enemies_list: if self.rect.colliderect(enemy): self.kill() #update position self.rect.x -= self.dx self.rect.y -= self.dy This definitely isn't the best way to do it but I can't think of another way. If anyone has done this or can help that would be awesome!

  • CSS: Javascript code out there that could draw form squares to copy to a real form?

    - by Dr. Zim
    I end up doing a lot of this to draw forms in boxes. This does an address block: position: absolute;top: .2em; left: .2em; width: 2.4em;height: 1.2em; position: absolute;top: .2em; left: 3em; width: 12.4em; height: 1.2em; position: absolute;top: 1.7em; left: 3em; width: 12.4em;height: 1.2em; position: absolute;top: 3.2em; left: 3em; width: 12.4em;height: 1.2em; position: absolute;top: 4.7em; left: 3em; width: 12.4em;height: 1.2em; position: absolute;top: 6.2em; left: 3em; width: 7.6em; height: 1.2em; position: absolute;top: 6.2em; left: 10.9em; width: 1.6em; height: 1.2em; position: absolute;top: 6.2em; left: 12.8em; width: 2.5em; height: 1.2em; position: absolute;top: 7.7em; left: 3em; width: 7.6em;height: 1.2em; position: absolute;top: 9.2em; left: 3em; width: 7.6em;height: 1.2em; position: absolute;top: 10.7em; left: 3em; width: 1.2em;height: 1.2em; position: absolute;top: 10.7em; left: 4.5em; width: 10.9em; height: 1.2em; but what I really need is some Javascript that allows me to draw my forms on screen, then generate the CSS for my real ASP.NET MVC 2 partial views, allowing nudge and cell resizing with keystrokes. Anyone have any suggestions for something like this?

  • Positioning decorated series of div tags on screen using offset, DOM JQUERY RELATED

    - by Calibre2010
    Hi, I am using JQuery to position a series of div tags which basically use a class inside of the tag which decorates the divs as bars. So the div is a green box based on its css specifications to the glass. I have a list of STARTING postions, a list of left coordiantes- for the starting points I wish to position my DIV say 556, 560, 600 these automatically are generated as left positions in a list I have a list of ENDING postions, a list of left coordiantes- for the ending points I wish to position my DIV say 570, 590, 610 these automatically are generated as left positions in a list now for each start and end position, the bar(green box) i want to be drawn with its appropriate width as follows. so say f is the offset or position of the start and ff the offset or position of the end : Below draws the green box based on only one start and end position LEFT. if (f.left != 0) { $("#test").html($("<div>d</div>")).css({ position: 'absolute', left: (f.left) + "px", top: (f.top + 35) + "px", width: (ff.left - f.left) + 25 + "px" }).addClass("option1"); } I am looking to loop through the list of positons in the list and draw multiple green boxs based on the positions on the screen. The above code draws just one green box from the last offset position.

  • Trying to right click on code in VS2008 causes lockup.

    - by Adam Haile
    Working on a Win32 DLL using Visual Studio 2008 SP1 and, since yesterday, whenever I try to right click on code, to go to a variable definition for example, VS completely locks up and I have to manually kill the process. To make it even weirder, whenever this happens the devenv.exe process uses exactly 25% of the CPU. And I mean exactly, never 24%, never 26%, always 25% Also, I've run ProcMon to see if devenv is actually doing something, but it's doing absolutely nothing external of the process. No disk, network, registry access. Nothing. This is getting really aggravating because I have a large code base to deal with and the only other way of jumping to the definition is to first search for it. Has anyone run into a similar issue? And, better yet, know a fix?

  • How to insert multiple check-box values inside database when one or more will be left unchecked?

    - by Sally
    I have a form that contains 5 check boxes. The user may select one or more of these check boxes. The user may select 2 and leave 3 unchecked or select 4 and leave one unchecked and so on, in that case how can I write the php/mysql code that will insert the form data into the database. With just one selection it's easy, I would do: $checkbox_value = $_POST['i_agree']; mysql_query("INSERT INTO terms (user, pass, conditions) VALUES ('$user','$pass','$checkbox_value')"); But how can I write this when there are multiple check box options and only one or more of them will be checked? I want to insert them all in one column called "tags" separated by commas.

  • T9 patented while QWERTY is not?

    - by Marco W.
    I've seen that there are lots of custom keyboards for Android, but all are QWERTY keyboards. I couldn't find any keyboard with T9 layout. Is this because T9 is patented and the QWERTY layout is not? So if I made a T9 keyboard, I would have to pay patent fees? So what does the patent protect when you look at T9? Only the layout? Or the prediction engine? The problem is, this way of predicting words is the only one that makes sense for this layout ...

  • Storing hierarchical template into a database

    - by pduersteler
    If this title is ambiguous, feel free to change it, I don't know how to put this in a one-liner. Example: Let's assume you have a html template which contains some custom tags, like <text_field />. We now create a page based on a template containing more of those custom tags. When a user wants to edit the page, he sees a text field. he can input things and save it. This looks fairly easy to set up. You either have something like a template_positions table which stores the content of those fields. Case: I now have a bit of a blockade keeping things as simple as possible. Assume you have the same tag given in your example, and additionally, <layout> and <repeat> tags. Here's an example how they should be used: <repeat> <layout name="image-left"> <image /> <text_field /> </layout> <layout name="image-right"> <text_field /> <image /> </layout> </repeat> We now have a block which can be repeated, obviously. This means: when creting/editing a page containing such a template block, I can choose between a layout image-left and image-right which then gets inserted as content element (where content for <image /> and <text_field /> gets stored). And because this is inside a <repeat>, content elements from the given layouts can be inserted multiple times. How do you store this? Simply said, this could be stored with the same setup I've wrote in the example above, I just need to add a parent_id or something similiar to maintain a hierarchy. but I think I am missing something. At least the relation between an inserted content element and the origin/insertion point is missing. And what happens when I update the template file? Do I have to give every custom tag that acts as editable part of a template an identifier that matches an identifier in the template to substitue them correctly? Or can you think of a clean solution that might be better?

  • Matlab: How to find the right-most point of a white line within the imrect?

    - by mchlfchr
    i've got a question regarding the imrect() function, which is part of the image processing toolbox in MatLab. I'd like to find a starting point within an image. I use the imrect function for setting a region to limit and specify the lookup area, but I can't get the point where the ROI mask is getting back mapped to the original size of the image. As you can see on the image there is a specified rectangle (cyan-colored), which I want to inspect for the white line, especially the nearest point to the right edge of the rectangle. I experimentated with only looking up on the last column of the rectangle, but as I mentioned before, the re-mapping onto the global image coordinates failed. So in this example, the white point I'd like to get would be around (98,302) The original (x,y) coordinates are relevant, so a cropping of the image to the rectangle is not acceptable. So, do you have any ideas? Thanks for any helping comments. Kind regards,
