  • I want to make "stuff" on the web, is a BsC. in Computers necessary/overkill? [on hold]

    - by notypist
    I'm 24 and have a lead role in a major news outlet in my country, with a good pay and public image in the horizon. I hold a job that was previously held by people with 15-20 years of experience and considered one of the top 5 news anchors in my country. My passion though, is computers. The web, to be precise. I was a problogger at a very young age. I hacked my way through CSS and some basic HTML and PHP. But I want to move forward - I want to CREATE not just STRUCTURE things. Giving up the present (and especially the seemingly promising future) in my current industry is hard, my friends raise their eyebrows... I'm considering a BsC. in computer Engineering - but my stats are short of getting into a good university for this discipline. Plus, I'm not the best with math - although I do exceptionally well in statistics and other numbers that are more applicable to real life. I tried learning PHP through online websites, but that just "doesn't cut it" for me. Nope. So what are my options here? if I don't want to build hardware or and deal with overly-complex algorithmic but would like, for example - to build a well functioning iPhone and iPad app, or a SaaS, a startup...do I have to go the BsC. route? I don't see any option to get an "official" education in strictly "web" concepts and languages.. Note: I'm well off financially, so I'm doing this more to be able to create stuff, rather than get a job in a corporations. Although if I land somewhere high, that might be an option. But my main concern is getting the tools.

  • Is it normal for GRUB to take some time (15+s) after I choose what to boot?

    - by zarnaik
    I had been planning to change the background of my bootloader for a while, and finally got to it. Now the black screen I get for quite some time was made clear. It is still GRUB, because the background image stays, while all of the text is gone. Then it just simply shows the Lubuntu loading screen for, usually, not more than 3 seconds. I run Lubuntu 12.10. My question is, is this normal behaviour or is something going wrong, causing GRUB to take longer? Here are the contents of my grub file located at /etc/default/ : # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT=0 #GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX="" GRUB_BACKGROUND="/usr/share/lubuntu/wallpapers/1210-Windmill_by_Ferran_Reyes.png" # Uncomment to enable BadRAM filtering, modify to suit your needs # This works with Linux (no patch required) and with any kernel that obtains # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...) #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef" # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE=640x480 # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID=true # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1" If you need any other information please tell me and I'll do my best to provide it. :)

  • Working in Germany (Munich) [closed]

    - by adri
    My husband and I are relocating to Munich in August (He's German). I have been looking for jobs online since I heard that software developers are in great demand. And by the looks of it, seems to be correct. There are lots of offers on line but I have a problem, my german is not spectacular. I would rate it as basic. Good to be a tourist but not good to write anything formal, not even my cover letter. So I was wondering how hard is really going to be to find a job for me with virtually no german (I'm studying, but good german is not going to happen over night). Also, would it be possible to secure a job before arriving to Germany? I have nearly 10 years of working experience developing software, mostly in .net (c#, vb, winForms, asp.net) but I also know java. 3 years experience as a team leader for groups of up to 8 people. In the last couple of years I've been working mostly on digitalization of documents (such as birth certificates and the like) but I'm more than willing to try other fields Also I speak English, Spanish, Italian, a bit of portuguese and of course a bit of german.

  • Drawning with canvas - problem with sizing [closed]

    - by pioncz
    For example i made 2 canvas with size 500px x 500px and 100px x 100px to see how fillrect works and i found that canvas.fillrect doesnt takes px for arguments, and my question is: how to make pixels as arguments or how to count these arguments for pixels? This is example: <html xmlns="http://www.w3.org/1999/xhtml"> <head> <script type="text/javascript"> function draw() { var canvas = document.getElementById('myCanvas'); var ctx = canvas.getContext('2d'); ctx.fillStyle = '#00f'; ctx.fillRect (0, 0,100, 100); var canvas2 = document.getElementById('myCanvas2'); var ctx2 = canvas2.getContext('2d'); ctx2.fillStyle = '#0f0'; ctx2.fillRect (0, 0, 100, 100); } </script> </head> <body onLoad="draw();"> <canvas id="myCanvas" style="background:black;width:500px;height:500px;display:block;position:absolute;top:0px;left:0px;"> </canvas> <canvas id="myCanvas2" style="background:purple;width:100px;height:100px;display:block;position:absolute;top:0px;left:0px;"> </canvas> </body> </html>

  • IE6 iframe anchor links moves iframe up

    - by WastedSpace
    Hi, Having a real head scratching moment... I have a site where there is a footer div that always sits at the bottom of the screen (26px high), and above that I have an iFrame which sizes to 100% of the remaining height. This works well. Even clicking on anchor links inside the iframe works as it should in all browsers (apart from IE6). Unfortunately I still have to support IE6. What is happening in IE6 is that the footer jumps up the page with the iframe still above it when I click on an anchor link. The top part of the iframe is cut off. Even the iframe's scroll bars disappear under the top of the browser. I have created some screen shots to show you what I mean. I have blurred out the actual data for now. How it should look (and does look) in other browsers: http://img100.imageshack.us/i/screen1om.jpg/ How it looks in IE6 before clicking on an anchor link: http://img532.imageshack.us/i/screen2e.jpg/ (I had to make the iframe's height 95%, because if I set it to 100% height weirdly it wouldn't show anything...) How it looks in IE6 after clicking on an anchor link: http://img214.imageshack.us/i/screen3g.jpg/ It's hard for me to show the fool code I am using, as there are lots of other things going on (of which I'm confident doesn't affect the layout), so will try to summarise: The html code (simplified): <div id="ifra"><iframe src="home.php" frameborder="0" name="content_pane" id="content_pane" marginheight="10" marginwidth="10"></iframe></div> <h1 class="toolbar"><a id="footerlink">Site Name</a></h1> The CSS (simplified): html, body { overflow: hidden; } html, body, iframe { height: 100%; } body { padding: 0; margin: 0; } #ifra, iframe { position: absolute; width: 100%; left: 0; } #ifra { top: 0px; bottom: 26px; } iframe { border: 0 none; } .toolbar { height: 26px; background-color: #C2C7C9; position: fixed; bottom: 0; width: 100%; background-image: url(bg.png); background-repeat: repeat-x; background-position: left top; } IE8 specific CSS: #ifra, .toolbar { position: fixed; } IE7 specific CSS: html { padding: 0px; } #ifra, iframe { position: absolute; } #ifra { top: 0px; bottom: 26px; } * html body { padding /**/: 100px 0 50px 0; overflow-y /**/: hidden; } IE6 specific CSS: .toolbar { position: fixed; } * html { overflow-y: hidden; } * html body { overflow-y: auto; height: 100%; } * html .toolbar { position: absolute; } iframe { height: 95%; } #ifra { height: 100%; } I know it's not ideal not seeing the full code, but just wondering if there is anything jumping out at anyone from these lines of code? By the way I did consider dropping the div surrounding the iframe, but for some reason the scroll bars would disappear under the footer in all browsers... Thanks for looking! Ali.

  • Setting height of div equal to containing div

    - by Syom
    i have the following simple script <div id="content"> <div id="left"> <div id="menu"> <ul> <li>menu</li> </ul> </div> <div id="left_ad"> </div> </div> <div id="middle"> some text here... </div> <div id="right"> <div id="right_ad"> <div id="ad2"> </div> </div> </div> </div> css: #content { margin: 0; padding: 0; overflow: hidden; position: relative; } #left { float: left; width:25%; margin-left:0; margin-right:0; margin-top:0; margin-bottom:-5000px; padding-left:0; padding-right:0; padding-top:0; padding-bottom:5000px; } #middle { background-image:url("http://localhost/kino/img/theme.png"); background-repeat:no-repeat; float: left; width:50%; margin-left:0; margin-right:0; margin-top:0; margin-bottom:-5000px; padding-left:0; padding-right:0; padding-top:0; padding-bottom:5000px; } #right { float: left; width:25%; margin-left:0; margin-right:-1px; margin-top:0; margin-bottom:-5000px; padding-left:0; padding-right:0; padding-top:0; padding-bottom:5000px; } #left_ad { background-image:url("http://localhost/kino/img/lens1.png"); background-repeat:no-repeat; min-height:498px; margin-left: auto; margin-right: auto; margin-top:31px; padding:0; width: 188px; position: relative; height: 100%; } as you see, left, middle and right have the same size of heigth, which is equal to max of them. and now, what is the question, i want left_ad to have the same heigth too. how can i set the heigth of left_id is equal to left? thanks

  • Animate button on MouseOver and MouseDown

    - by haagel
    I'm making my own ControlTemplate for a standard Button in WPF. I want to change the background of my button when the user hovers over the button with the mouse, but also when the user presses the button (to yet another color). This seems like a common behavior, but I can't get it to work. My template consists of a Border with an Image inside. It is the background color (a gradient really) of the Border that I want to animate. I have triggers in my template that activates animations (storyboards). The MouseOver/Out works just fine. My problem occurs when I press the button. The Press animation runs as it should, and so does the Release animation. But after this the MouseOut will never run. The button gets stuck in the MouseOver state. What am I doing wrong? <ControlTemplate TargetType="{x:Type Button}"> <ControlTemplate.Resources> <Storyboard x:Key="MouseOverAnimation"> <ColorAnimation Storyboard.TargetName="ButtonBorderGradientStop1" Storyboard.TargetProperty="Color" To="#ffefefff" Duration="0:0:0.2" /> <ColorAnimation Storyboard.TargetName="ButtonBorderGradientStop2" Storyboard.TargetProperty="Color" To="#ffc7c7ff" Duration="0:0:0.2" /> </Storyboard> <Storyboard x:Key="MouseOutAnimation"> <ColorAnimation Storyboard.TargetName="ButtonBorderGradientStop1" Storyboard.TargetProperty="Color" To="#ffeeeeee" Duration="0:0:0.2" /> <ColorAnimation Storyboard.TargetName="ButtonBorderGradientStop2" Storyboard.TargetProperty="Color" To="#ffcccccc" Duration="0:0:0.2" /> </Storyboard> <Storyboard x:Key="MouseDownAnimation"> <ColorAnimation Storyboard.TargetName="ButtonBorderGradientStop1" Storyboard.TargetProperty="Color" To="#ffc7c7ff" Duration="0:0:0.1" /> <ColorAnimation Storyboard.TargetName="ButtonBorderGradientStop2" Storyboard.TargetProperty="Color" To="#ff9a9aff" Duration="0:0:0.1" /> </Storyboard> <Storyboard x:Key="MouseUpAnimation"> <ColorAnimation Storyboard.TargetName="ButtonBorderGradientStop1" Storyboard.TargetProperty="Color" To="#ffefefff" Duration="0:0:0.1" /> <ColorAnimation Storyboard.TargetName="ButtonBorderGradientStop2" Storyboard.TargetProperty="Color" To="#ffc7c7ff" Duration="0:0:0.1" /> </Storyboard> </ControlTemplate.Resources> <Border x:Name="ButtonBorder" CornerRadius="0" BorderBrush="#55aaaaaa" BorderThickness="1" Width="23" Height="22"> <Border.Background> <LinearGradientBrush StartPoint="0,0" EndPoint="0,1"> <GradientBrush.GradientStops> <GradientStop x:Name="ButtonBorderGradientStop1" Color="#ffeeeeee" Offset="0.0" /> <GradientStop x:Name="ButtonBorderGradientStop2" Color="#ffcccccc" Offset="1.0" /> </GradientBrush.GradientStops> </LinearGradientBrush> </Border.Background> <Image x:Name="ButtonIcon" Source="icons/searchicon_bw.png" Width="16" Height="16" /> </Border> <ControlTemplate.Triggers> <Trigger Property="IsMouseOver" Value="True"> <Trigger.EnterActions> <BeginStoryboard Storyboard="{StaticResource MouseOverAnimation}" /> </Trigger.EnterActions> <Trigger.ExitActions> <BeginStoryboard Storyboard="{StaticResource MouseOutAnimation}" /> </Trigger.ExitActions> </Trigger> <Trigger Property="IsPressed" Value="True"> <Trigger.EnterActions> <BeginStoryboard Storyboard="{StaticResource MouseDownAnimation}" /> </Trigger.EnterActions> <Trigger.ExitActions> <BeginStoryboard Storyboard="{StaticResource MouseUpAnimation}" /> </Trigger.ExitActions> </Trigger> </ControlTemplate.Triggers> </ControlTemplate>

  • Why are these divs not aligned and space between?

    - by acidzombie24
    Why isnt everything aligned? No yellow should be visible and no orange should be visible except for the right side and bottom left where theres space for another image. Basically my images are pretty much aligned to the center (i have other pics not in this example which is easier to see). However in this case when i have 150px height image the 150 width seems start lower. Also why are there spaces in between <!DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"><head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>ldfk;sd</title> <style type="text/css"> div.ImgGallery { max-width: 630px; background: orange; } .ImgGallery div { display: inline; } /* http://www.brunildo.org/test/img_center.html */ .ImgGallery div div { display: table-cell; text-align: center; background: gray; width: 150px; height: 150px; } .ImgGallery div{ background: yellow; vertical-align: middle; } //.ImgGallery div div :nth-child(2n+1) { background: red; } .ImgGallery * { vertical-align: middle; } .ImgGallery a { display: block; } .ImgGallery a * { border-style: none; } </style> </head> <div class="smallGallery"> <div class="ImgGallery"> <div><div><a href="http://google.com"><img src="a.jpg" alt="a.jpg"></a></div></div> <div><div><a href="http://google.com"><img src="a.jpg" alt="a.jpg"></a></div></div> <div><div><a href="http://google.com"><img src="a.jpg" alt="a.jpg"></a></div></div> <div><div><a href="http://google.com"><img src="a.jpg" alt="a.jpg"></a></div></div> <div><div><a href="http://google.com"><img src="a.jpg" alt="a.jpg"></a></div></div> <div><div><a href="http://google.com"><img src="b.jpg" alt="a.jpg"></a></div></div> <div><div><a href="http://google.com"><img src="a.jpg" alt="a.jpg"></a></div></div> <div><div><a href="http://google.com"><img src="a.jpg" alt="a.jpg"></a></div></div> <div><div><a href="http://google.com"><img src="b.jpg" alt="a.jpg"></a></div></div> <div><div><a href="http://google.com"><img src="a.jpg" alt="a.jpg"></a></div></div> <div><div><a href="http://google.com"><img src="a.jpg" alt="a.jpg"></a></div></div> </div></div> </body></html>

  • RelativeLayout, ScrollView and navigation bar at bottom

    - by MicNeo
    What I want to do is, make layout like this: Title Date Long text with scrolling Navigation bar stick to the bottom Well I have done everything, however there is a little problem with scrolling. I want only to scroll text. Title and date should be stick to the top, and nav bar to the bottom of activity. And yes, it works, but my nav bar overlaps text :/ I tried everything, there is one solution I found, set fixed height for Scrollview, but this will not work on every devices well, isn't it? I probably could do some calculation in code, and on it change height, but I would like to stay in XML. Any one have any suggestions?

  • How to manage a MotionEvent going from one View to another?

    - by Darren
    I have a SurfaceView that takes up part of the screen, and some buttons along the bottom. When a button is pressed and the user drags, I want to be able to drag a picture (based on the button) onto the SurfaceView and have it drawn there. I want to be able to use clickListeners and the like, and not just have a giant SurfaceView with me writing code to detect where the user pressed and if it's a button, etc. I have somewhat of a solution, but it seems a bit of a hack to me. What is the best way to accomplish this using the framework intelligently? Part of my XML: <RelativeLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@drawable/background"> <!-- Place buttons along the bottom --> <RelativeLayout android:id="@+id/bottom_bar" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="40dip" android:layout_alignParentBottom="true" android:background="@null"> <ImageButton android:id="@+id/btn_1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerVertical="true" android:background="@null" android:src="@drawable/btn_1"> </ImageButton> <!-- More buttons here... --> </RelativeLayout> <!-- Place the SurfaceView in a frame so we can stack on top of it --> <FrameLayout android:layout_width="fill_parent" android:layout_height="0px" android:layout_weight="1" android:layout_above="@id/bottom_bar"> <com.project.question.MySurfaceView android:id="@+id/my_view" android:layout_width="fill_parent" android:layout_height="fill_parent" /> </FrameLayout> And the relevant Java code in MySurfaceView, which extends SurfaceView. mTouchX and Y are used in the onDraw method to draw the image: @Override public boolean onTouchEvent(MotionEvent event){ mTouchX = (int) event.getX(); mTouchY = (int) event.getY(); return true; } public void onButtonTouchEvent(MotionEvent event){ event.setLocation(event.getX(), event.getY() + mScreenHeight); onTouchEvent(event); } Finally, the activity: @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.my_surface); mView = (MySurfaceView) findViewById(R.id.my_view); mSurfaceHeight = mView.getHeight(); mBtn = (ImageButton) findViewById(R.id.btn_1); mBtn.setOnTouchListener(mTouchListener); } OnTouchListener mTouchListener = new OnTouchListener() { public boolean onTouch(View v, MotionEvent event) { int [] location = new int[2]; v.getLocationOnScreen(location); event.setLocation(event.getX() + location[0], event.getY()); mView.onButtonTouchEvent(event); return true; } }; Strangely, one has to add to the x-coordinate in the activity, then add to the y coordinate in the View. Otherwise, it doesn't show up in the correct position. If you add nothing, something drawn using mTouchX and mTouchY will show up in the upper left corner of the SurfaceView. Any direction would be greatly appreciated. If I'm going about this completely the wrong way, that would be good information too.

  • Pyramind of DIVs

    - by sebastian
    Hi there, I'm trying to build a pyramid that's made of 4 DIVs. The layout looks like this: ------ | #1 | ------ ---------------- | #2 | #3 | #4 | ---------------- Moreover I need 3 additional DIVs starting at the center DIV (#3) and containing either #1, #2 or #3 additionally. These DIVs are used the build a sliding effect with jQueryUI later on. It's supposed to look like #1, #2 and #4 slide out of #3. The margin between the DIVs is supposed to be 2 pixels. I also want the whole block to be centered. Even with display: inline; and position: absolute; enabled on the visible and invisible DIVs I can't get the layout right. I used some negative margins and when it looked ok for the first time I saw that my top DIV was positioned outside of the html body. I suppose there is a more simple and elegant way to achieve what I want. Thanks in advance Sebastian Here's what I've got so far: HTML: <div id="centerbox"> <div id="main">main</div> <div id="rail_top"> <div id="top">top</div> </div> <div id="rail_left"> <div id="left">left</div> </div> <div id="rail_right"> <div id="right">right</div> </div> </div> CSS: #centerbox { height: 602px; width: 904px; margin-top: 640px; margin-left: auto; margin-right: auto; } /* blue */ #main { background-color: #33F; height: 300px; width: 300px; margin: 2px; z-index: 9999; position: absolute; display: inline; margin-left: 302px; } /* green */ #top { background-color: #3F0; height: 300px; width: 300px; z-index: 1; position: absolute; display: inline; } /* pink */ #left { background-color: #F06; height: 300px; width: 300px; z-index: 1; } /* orange */ #right { background-color: #FC0; height: 300px; width: 300px; z-index: 1; margin-left: 302px; } #rail_top { height: 602px; width: 300px; display: inline; position: absolute; margin-top: -300px; margin-left: 302px; } #rail_left { height: 300px; width: 602px; float: left; position: absolute; display: inline; margin-top: 2px; } #rail_right { height: 300px; width: 602px; float: right; position: absolute; display: inline; margin-left: 302px; margin-top: 2px; }

  • Cross Browser Issue

    - by dazedandconfused
    My background is in WinForms programming and I'm trying to branch out a bit. I'm finding cross-browser issues a frustrating barrier in general, but have a specific one that I just can't seem to work through. I want to display an image and place a semi-transparent bar across the top and bottom. This isn't my ultimate goal, of course, but it demonstrates the problem I'm having ina a relatively short code fragment so let's go with it. The sample code below displays as intended in Chrome, Safari, and Firefox. In IE8, the bar at the bottom doesn't appear at all. I've researched it for hours but just can't seem to come up with the solution. I'm sure this is some dumb rookie mistake, but gotta start somewhere. Code snippet... <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title></title> <script type="text/javascript" language="javascript"> </script> <style type="text/css"> .workarea { position: relative; border: 1px solid black; background-color: #ccc; overflow: hidden; cursor: move; -moz-user-focus: normal; -moz-user-select: none; unselectable: on; } .semitransparent { filter: alpha(opacity=70); -moz-opacity: 0.7; -khtml-opacity: 0.7; opacity: 0.7; background-color: Gray; } </style> </head> <body style="width: 800px; height: 600px;"> <div id="workArea" class="workarea" style="width: 800px; height: 350px; left: 100px; top: 50px; background-color: White; border: 1px solid black;"> <img alt="" src="images/TestImage.jpg" style="left: 0px; top: 0px; border: none; z-index: 1;" /> <div id="topBar" class="semitransparent" style="position: absolute;width: 800px; height: 75px; left: 0px; top: 0px; min-height: 75px; border: none; z-index: 2;" /> <div id="bottomBar" class="semitransparent" style="position: absolute; width: 800px; height: 75px; left: 0px; top: 275px; min-height: 75px; border: none; z-index: 2;" /> </div> </body> </html>

  • Lock-Free, Wait-Free and Wait-freedom algorithms for non-blocking multi-thread synchronization.

    - by GJ
    In multi thread programming we can find different terms for data transfer synchronization between two or more threads/tasks. When exactly we can say that some algorithem is: 1)Lock-Free 2)Wait-Free 3)Wait-Freedom I understand what means Lock-free but when we can say that some synchronization algorithm is Wait-Free or Wait-Freedom? I have made some code (ring buffer) for multi-thread synchronization and it use Lock-Free methods but: 1) Algorithm predicts maximum execution time of this routine. 2) Therad which call this routine at beginning set unique reference, what mean that is inside of this routine. 3) Other threads which are calling the same routine check this reference and if is set than count the CPU tick count (measure time) of first involved thread. If that time is to long interrupt the current work of involved thread and overrides him job. 4) Thread which not finished job because was interrupted from task scheduler (is reposed) at the end check the reference if not belongs to him repeat the job again. So this algorithm is not really Lock-free but there is no memory lock in use, and other involved threads can wait (or not) certain time before overide the job of reposed thread. Added RingBuffer.InsertLeft function: function TgjRingBuffer.InsertLeft(const link: pointer): integer; var AtStartReference: cardinal; CPUTimeStamp : int64; CurrentLeft : pointer; CurrentReference: cardinal; NewLeft : PReferencedPtr; Reference : cardinal; label TryAgain; begin Reference := GetThreadId + 1; //Reference.bit0 := 1 with rbRingBuffer^ do begin TryAgain: //Set Left.Reference with respect to all other cores :) CPUTimeStamp := GetCPUTimeStamp + LoopTicks; AtStartReference := Left.Reference OR 1; //Reference.bit0 := 1 repeat CurrentReference := Left.Reference; until (CurrentReference AND 1 = 0)or (GetCPUTimeStamp - CPUTimeStamp > 0); //No threads present in ring buffer or current thread timeout if ((CurrentReference AND 1 <> 0) and (AtStartReference <> CurrentReference)) or not CAS32(CurrentReference, Reference, Left.Reference) then goto TryAgain; //Calculate RingBuffer NewLeft address CurrentLeft := Left.Link; NewLeft := pointer(cardinal(CurrentLeft) - SizeOf(TReferencedPtr)); if cardinal(NewLeft) < cardinal(@Buffer) then NewLeft := EndBuffer; //Calcolate distance result := integer(Right.Link) - Integer(NewLeft); //Check buffer full if result = 0 then //Clear Reference if task still own reference if CAS32(Reference, 0, Left.Reference) then Exit else goto TryAgain; //Set NewLeft.Reference NewLeft^.Reference := Reference; SFence; //Try to set link and try to exchange NewLeft and clear Reference if task own reference if (Reference <> Left.Reference) or not CAS64(NewLeft^.Link, Reference, link, Reference, NewLeft^) or not CAS64(CurrentLeft, Reference, NewLeft, 0, Left) then goto TryAgain; //Calcolate result if result < 0 then result := Length - integer(cardinal(not Result) div SizeOf(TReferencedPtr)) else result := cardinal(result) div SizeOf(TReferencedPtr); end; //with end; { TgjRingBuffer.InsertLeft } RingBuffer unit you can find here: RingBuffer, CAS functions: FockFreePrimitives, and test program: RingBufferFlowTest Thanks in advance, GJ

  • Jquery .Animate Width Problem.

    - by smoop
    Thanks in advance for any-help with this, I'll try and explain it well. I have a container of 1000px width and 220px height, in this I will have three columns 220px in height but with different widths (77px, 200px and 300px). When you click one div it will open to a fixed size (the same for each, say 400px) and the others which are not clicked will shrink back to their original sizes (77px, 200px and 300px). Like an accordian with different widths.. My jquery is getting there but not quite, I know how to create an Event on click, I know from there I need to shrink everything but the one I clicked back to their orignal size. I finish but making the one clicked expand to the size it needs to be. jsfiddle here! $(document).ready(function(){ // Your code here $('.section').click(function() { $('.section').not(this).animate({width:"77px"},400); //alert('clicked!'); $(this).animate({width:"400px"},400); }); }); <div id="pictureNavContainer"> <div class="section pictureSectionOne" id="1"></div> <div class="section pictureSectionTwo" id="2"></div> <div class="section pictureSectionThree" id="3"></div> </div> <style> #pictureNavContainer{background-color:#262626; width:1000px; height:220px; overflow:hidden;} .pictureSectionOne{float:left; background:yellow; height:220px; width:77px;} .pictureSectionTwo{float:left; background:red; height:220px; width:177px;} .pictureSectionThree{float:left; background:blue; height:220px; width:400px;} </style> I figured a kind of solution: <script> $(document).ready(function(){ // Your code here $('.section').click(function() { $('#1').animate({width:"50px"},400); $('#2').animate({width:"100px"},400); $('#3').animate({width:"200px"},400); //alert('clicked!'); $(this).animate({width:"400px"},400); }); }); </script> But the code isnt very good.. but it works This: $(function(){ var $sections = $('.section'); var orgWidth = []; var animate = function() { var $this = $(this); $sections.not($this).each(function(){ var $section = $(this), org = orgWidth[$section.index()]; $section.animate({ width: org }, 400); }); $this.animate({ width: 400 }, 400); }; $sections.each(function(){ var $this = $(this); orgWidth.push($this.width()); $this.click(animate); }); });

  • Warning: comparison with string literals results in unspecified behaviour

    - by nunos
    So I starting the project of writing a simplified sheel for linux in c. I am not at all proficient with c nor with Linux that's exactly the reason I decided it would be a good idea. Starting with the parser, I have already encountered some problems. The code should be straightforward that's why I didn't include any comments. I am getting a warning with gcc: "comparison with string literals results in unspecified behaviour" at the lines commented with "WARNING HERE" (see code below). I have no idea why this causes an warning, but the real problem is that even though I am comparing an "<" to an "<" is doesn't get inside the if... I am looking for an answer for the problem explained, however if there's something that you see in the code that should be improved please say so. Just take in mind I am not that proficient and that this is still a work in progress (or better yet, a work in start). Thanks in advance. #include <stdio.h> #include <unistd.h> #include <string.h> typedef enum {false, true} bool; typedef struct { char **arg; char *infile; char *outfile; int background; } Command_Info; int parse_cmd(char *cmd_line, Command_Info *cmd_info) { char *arg; char *args[100]; int i = 0; arg = strtok(cmd_line, " \n"); while (arg != NULL) { args[i] = arg; arg = strtok(NULL, " \n"); i++; } int num_elems = i; cmd_info->infile = NULL; cmd_info->outfile = NULL; cmd_info->background = 0; int iarg = 0; for (i = 0; i < num_elems; i++) { if (args[i] == "&") //WARNING HERE return -1; else if (args[i] == "<") //WARNING HERE if (args[i+1] != NULL) cmd_info->infile = args[i+1]; else return -1; else if (args[i] == ">") //WARNING HERE if (args[i+1] != NULL) cmd_info->outfile = args[i+1]; else return -1; else cmd_info->arg[iarg++] = args[i]; } cmd_info->arg[iarg] = NULL; return 0; } void print_cmd(Command_Info *cmd_info) { int i; for (i = 0; cmd_info->arg[i] != NULL; i++) printf("arg[%d]=\"%s\"\n", i, cmd_info->arg[i]); printf("arg[%d]=\"%s\"\n", i, cmd_info->arg[i]); printf("infile=\"%s\"\n", cmd_info->infile); printf("outfile=\"%s\"\n", cmd_info->outfile); printf("background=\"%d\"\n", cmd_info->background); } int main(int argc, char* argv[]) { char cmd_line[100]; Command_Info cmd_info; printf(">>> "); fgets(cmd_line, 100, stdin); parse_cmd(cmd_line, &cmd_info); print_cmd(&cmd_info); return 0; }

  • Android: MediaPlayer gapless or seamless Video Playing

    - by John Wang
    I can play the videos fine back to back by implementing the OnCompletionListener to set the data source to a different file. No problems there. I call reset() and prepare() just fine. What I haven't been able to figure out, is how to get rid of the 1-2 second gap screen flicker between the data source change and the new video starting. The gap shows a black screen, and I haven't found any way to get around it. I've tried setting the background of the parent view to an image, but it manages to bypass that. Even if the SurfaceView is transparent (which it is by default.) I've also tried to have the multiple video files played at the same time, and switching mediaplayer's display when one ends and the other is supposed to start. The last thing I tried, was to have a second view in the background that I show temporarily while the video is "preparing" and removing it when the video is ready to start. That also wasn't very seamless. Is there any way to get rid of that gap. Running a video in a loop works wonderfully and does exactly what I want with the exception that it's looking through the same video instead of playing a different one that I pick. main.xml <?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:background="@drawable/background" android:layout_height="fill_parent"> <SurfaceView android:id="@+id/surface" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_gravity="center"> </SurfaceView> </FrameLayout> Player.java public class Player extends Activity implements OnCompletionListener, MediaPlayer.OnPreparedListener, SurfaceHolder.Callback { private MediaPlayer player; private SurfaceView surface; private SurfaceHolder holder; public void onCreate(Bundle b) { super.onCreate(b); setContentView(R.layout.main); surface = (SurfaceView)findViewById(R.id.surface); holder = surface.getHolder(); holder.addCallback(this); holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); } public void onCompletion(MediaPlayer arg0) { File clip = new File(Environment.getExternalStorageDirectory(),"file2.mp4"); playVideo(clip.getAbsolutePath()); } public void onPrepared(MediaPlayer mediaplayer) { holder.setFixedSize(player.getVideoWidth(), player.getVideoHeight()); player.start(); } private void playVideo(String url) { try { File clip = new File(Environment.getExternalStorageDirectory(),"file1.mp4"); if (player == null) { player = new MediaPlayer(); player.setScreenOnWhilePlaying(true); } else { player.stop(); player.reset(); } player.setDataSource(url); player.setDisplay(holder); player.setOnPreparedListener(this); player.prepare(); player.setOnCompletionListener(this); } catch (Throwable t) { Log.e("ERROR", "Exception Error", t); } }

  • Android refresh StateListDrawable problem

    - by Max
    Hi all, I have a strange problem with StateListDrawable or maybe (probably) I'm missing something. I created a test application for it and the same problem occurs. So, this is my StateListDrawable resourse in file test_selection.xml <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_selected="true"> <shape android:shape="rectangle" android:background="#ff0000"> <corners android:radius="10dp" /> <gradient android:startColor="#ff5555" android:endColor="#ff5555" android:angle="0" /> </shape> </item> <item android:state_selected="false"> <shape android:shape="rectangle" android:background="#eeeeee"> <corners android:radius="10dp" /> <gradient android:startColor="#eeeeee" android:endColor="#eeeeee" android:angle="0" /> </shape> </item> </selector> It's a very simple selector that draw a red color for selected state and a white rect for the unselected one. My main.xml template is very simple. I simply use a TextView that uses the selection as background. <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" android:textSize="30dp" android:id="@+id/test_view_example" android:background="@drawable/test_selection"/> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/refresh" android:onClick="updateView" android:text="refresh"></Button> </LinearLayout> My Activity code is also very simple. public class TestDrawableStateActivity extends Activity { private final static int[] SELECTED_STATE = { android.R.attr.state_selected }; private final static int[] UNSELECTED_STATE = {}; private TextView textView; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); textView = (TextView) findViewById(R.id.test_view_example); } @Override protected void onResume() { super.onResume(); // Carichiamo la Drawable if(textView.getBackground().setState(SELECTED_STATE)){ textView.invalidate(); } } public void updateView(View view) { if(textView.getBackground().setState(SELECTED_STATE)){ textView.invalidate(); }; } } When Activity starts I try to set the state of my Drawable (the StateListDrawable) with the value SELECTED. It seems all very simple.... but the problem is that the state is not shown. If, later, I click a button and execute the method updateView() the state changes. Where is my problem? Where am I wrong? Thankx a lot Max

It is a horizontal menu with dropdown submenus <div id="menu"> <ul> <li><h2>Computers</h2> <ul> <li>subitem <ul><li>subitems</li> </li> <li>submitem</li> <li>submitem</li> </li> <li><h2>Network</h2> <ul><li>subitems</li> </li> </ul> </div> I am using the minified version of the whatever hover script. Checked few posts here on this issue but couldn't solve the problem. The submenus are not appearing on IE6 and IE7. I trid adding <!--[if lt IE 8]> but no results...
