• Single intent to let user take picture OR pick image from gallery in Android

  - by Damian

  I'm developing an app for Android 2.1 upwards. I want to enable my users to select a profile picture within my app (I'm not using the contacts framework). The ideal solution would be to fire an intent that enables the user to select an image from the gallery, but if an appropriate image is not available then use the camera to take a picture (or vice-versa i.e. allow user to take picture but if they know they already have a suitable image already, let them drop into the gallery and pick said image). Currently I can do one or the other but not both. If I go directly into camera mode using MediaStore.ACTION_IMAGE_CAPTURE then there is no option to drop into the gallery. If I go directly to the gallery using Intent.ACTION_PICK then I can pick an image but if I click the camera button (in top right hand corner of gallery) then a new camera intent is fired. So, any picture that is taken is not returned directly to my application. (Sure you can press the back button to drop back into the gallery and select image from there but this is an extra unnecessary step and is not at all intuitive). So is there a way to combine both or am I going to have to offer a menu to do one or the other from within my application? Seems like it would be a common use case...surely I'm missing something?

• unique items from an observableArray of object properties

  - by Joe

  I'm trying to extract unique properties from a knockout.js observableArray of objects, to populate a drop menu. Being new to knockout, I'm really struggling with this! I want to iterate over a contacts list, and populate a drop menu with a unique value from each person object within the observableArray. So in my code example below, I wish to populate my drop menu with a list of people 'type' - family, friend etc. Looking on Google, I found a similar function, but it does not return any values, even if I console.log the results? //dummy data more rows in actual code... var people = [ { name: "Contact 1", address: "1, a street, a town, a city, AB12 3CD", tel: "0123456789", email: "[email protected]", type: "family" }, { name: "Contact 2", address: "1, a street, a town, a city, AB12 3CD", tel: "0123456789", email: "[email protected]", type: "friend" } ]; function ContactsViewModel(people) { var self = this; self.contacts = ko.observableArray(people); self.uniqueSelect = ko.dependentObservable(function() { return( ko.utils.arrayGetDistinctValues(self.contacts().type).sort()); }, self); }; ko.applyBindings(new ContactsViewModel()); And HTML template <p>Show me: <select data-bind="options: ContactsViewModel.uniqueSelect"></select></p> Any help appreciated, as a noob I'm lost! Thanks

• How can I set a Java applet transparency to show contents behind it?

  - by yuri

  I've got a web page with an applet inside. This applet is a drop target on a drag and drop action from the OS, I simply take an image from a folder, drag it on the applet and something happens. I give this webpage to a graphic designer and he ask to if he can put an image behind the java applet so he can simulate to change the background using CSS (it is a skinned app and graphic design can change during execution). Practically i supposed to do: <div> <applet width="50" height="50" /> </div> with this CSS: div { width:50px; height:50px; background-image: url(image.jpg) center center no-repeat; } But it doesn't work (background is opaque). It is possible to set transparency to the applet without loosing drag and drop capabilities ? I'm searching something similar to flash wmode parameter. Better solutions implies only changes on the CSS/HTML without recompiling java class so the designing team can change the page structure without changing the Java.

• Javascript code works only when the page loads

  - by victor

  I have a page with a dropdown and two textboxes. The javascript code checks to make sure that if the dropdown says Appointment Made or Patient Scheduled, the appropriate text boxes will have dates in them. When the page loads and the drop down shows either of the two above, all works fine but when I change the drop down the script does not work. I have put an alert statament after the third line and do see that when I make a change to patient_status, the variable a gets updated but for some reason the script fails and does not prompt. For example if the page loads and Appointment Made is selected, the script will prompt, but if I change the drop down to Patient Scheduled, it will not prompt. Thank You. function calculate() { a= document.getElementById("EditRecordpatient_status").value; b= document.getElementById("EditRecordSurgery_Date").value; c= document.getElementById("EditRecordConsult_Date").value; alert(a); alert(b); alert(c); if (a=="Appointment Made" && c=="") { alert('You have scheduled a patient for consultation but the consult date is missing!'); return false; } else if (a=="Patient Scheduled" && b=="") { alert('You have scheduled a patient for surgery but the surgery date is missing!'); return false; } else { return true; } } document.getElementById("Mod0EditRecord").onclick=calculate;

• temporary tables within stored procedures on slave servers with readonly set

  - by lau

  Hi, We have set up a replication scheme master/slave and we've had problems lately because some users wrote directly on the slave instead of the master, making the whole setup inconsistent. To prevent these problems from happening again, we've decided to remove the insert, delete, update, etc... rights from the users accessing the slave. Problems is that some stored procedure (for reading) require temporary tables. I read that changing the global variable read_only to true would do what I want and allow the stored procedures to work correctly ( http://dev.mysql.com/doc/refman/5.0/en/server-system-variables.html#sysvar_read_only ) but I keep getting the error : The MySQL server is running with the --read-only option so it cannot execute this statement (1290) The stored procedure that I used (for testing purpose) is this one : DELIMITER $$ DROP PROCEDURE IF EXISTS test_readonly $$ CREATE DEFINER=dbuser@% PROCEDURE test_readonly() BEGIN CREATE TEMPORARY TABLE IF NOT EXISTS temp ( BT_INDEX int(11), BT_DESC VARCHAR(10) ); INSERT INTO temp (BT_INDEX, BT_DESC) VALUES (222,'walou'), (111,'bidouille'); DROP TABLE temp; END $$ DELIMITER ; The create temporary table and the drop table work fine with the readonly flag - if I comment the INSERT line, it runs fine- but whenever I want to insert or delete from that temporary table, I get the error message. I use Mysql 5.1.29-rc. My default storage engine is InnoDB. Thanks in advance, this problem is really driving me crazy.

• How to properly set button phase after dragging over button?

  - by irobeth

  I have a class (mxml) that extends Button while implementing drag/drop support. When I drag one of them onto another, the drag receiver stays stuck in its 'over' phase until I click on it (As if something about DragManager.acceptDragDrop is preventing the MouseEvent from getting to button) Is there a way to make a button re-evaluate its phase after the drop? I've tried fabricating a MouseEvent and sending it to rollOverHandler with no luck. This resembles the scenario in Button.as (lines 2606-2647) described like Drag over and up mouse down while out of Button roll over Button - stay in "up" phase mouse up while over Button - "over" phase continue with step 2 of first three sequences above This is my drag/drop handler private function dragDropHandler(event:DragEvent):void { trace("dropped"); var ib : IconButton = (event.dragInitiator as IconButton); if(this.data is Section) { if(ib.data is Item) { trace("ITEM"); //move an item into a section. var ae : AldonaEvent = new AldonaEvent(AldonaEvent.MOVE); ae.data = ib.data; dispatchEvent(ae); } else if(ib.data is Section) { trace("SECTION"); //change a section's parent. var ae : AldonaEvent = new AldonaEvent(AldonaEvent.MOVE); ae.data = ib.data; dispatchEvent(ae); } } //you can only drag stuff into sections. }

• jquery draggable/droppable issue

  - by Scarface

  Hey guys I have a drag and drop function that does not fully work. What I want to do is be able to drag and drop a picture into a div and have that picture pop up in the div. I have a list of 2 pictures right now, so I have the following function echoed for each picture. Both pictures are draggable and droppable, but the first one is the only one that appears in the div, regardless of which picture gets dragged in. I am not sure what is wrong because the jquery function seems to be unique to each picture. If any one has any suggestions I would appreciate it greatly. while ($row = mysql_fetch_assoc($query)) { $image=htmlentities($row['image']); //image name $uniqid=uniqid(); //unique id for jquery functions $dirname = "usercontent/$user/images/$image"; echo "<img id=\"$uniqid\" src=\"$dirname\" width=\"75\" height=\"75\"/>"; echo "<script> $(function() { $(\"#$uniqid\").draggable({ scroll: true, scrollSensitivity: 10, scrollSpeed: 10, revert: true, helper: 'clone', cursorAt: { cursor: 'move', top: 27, left: 27 } }); $(\"#droppable2, #droppable-background , #droppable2-innerer\").droppable({ greedy: true, activeClass: 'ui-state-hover', hoverClass: 'ui-state-active', drop: function(event, ui) { $(this).addClass('ui-state-highlight').find('> p').html('Dropped!'); $('#droppable-background').css(\"background-image\",\"url($dirname)\"); } }); }); </script>"; }

• passing string to a AJAX/JSON function

  - by Mikey1980

  I’m having trouble getting a AJAX/JSON function to work correctly. I had this function grabbing value from a drop down box but now I want to use an anchor tag to set it's value. I thought it would be easy to just use the onClick event to pass string to the function I was using for the drop down box but it doesn’t do anything. I’m stumped! Here how I set it up: 1st I add an onClick event… <a href="<?php echo Settings::get('app.webroot'); ?>?view=schedule&action=questions" onmouseout="MM_swapImgRestore();" onmouseover="MM_swapImage('bre','','template/images/schedule/bre_f2.gif',1) onclick="assignCallType('testing')";> 2nd I check main.js.php function assignCallType(type) { alert(type); //just for debugging new Request.JSON({ url: "ajax.php", onSuccess: function(rtndata,txt){ if (rtndata['STATUS'] != 'OK') alert('Error assigning call type to call'); }, onFailure: function (xhr) { alert('Error assigning call type to call'); } }).get({ 'action': 'assignCallType', 'call_type': type }); } 3rd Ajax.php: the variable is back in PHP and values don’t get added to the db, but I also didn’t get the alert from main.js.php if ($_GET['action'] == "assignCallType") { if ($USER->isInsideSales()) { $call_type = $_GET['call_type']; $_SESSION['callinfo']->setCallType($call_type); $_SESSION['callinfo']->save($callid); echo json_encode(array('STATUS'=>'OK')); } else { echo json_encode(array('STATUS'=>'DENIED')); } } Any idea where I am going wrong. The only difference between this and the working drop down is how the function was called, I used onchange="assignCallType(this.value)".

• The same C# code produces different output in Visio Professional and Premium

  - by user615993

  I have built a simple conversion Add In, but its behavior is unfortunately different with the different Visio Editions (Visio 2010 Professional and Visio 2010 Premium). The Add In takes a Process-Diagram created with Shapes from Stencil_1.vss and creates a new slightly different Process-Diagram with Shapes from Stencil_2.vsd. It loops through a Visio page and for each shape founded creates a new shapes from new master shape (from Stencil_2.vsd) and drop it into the new page. Geometry, captions etc. are the same, only the shape-appearance is changed. Below is the source diagram: When I run the code into Visio 2010 Professional the swimlane shapes are drawn correctly. When I run the same code from Visio Premium the swimlane appearance and layout are mismatched: Both times i drop the SAME Shape("Swimlane" from the same stencil) into the Page with the SAME Code fragment: Visio.Master vm = swimlane_stencil.Masters.get_ItemU(@"Swimlane"); Visio.Shape TargetShape = targetPage.Drop(vm, shape_x, shape_y); How could I ensure, that the code produces any time the same (correct) output? Must I disable any (premium)features in the swimlane-shapesheet?

• How do I refer to a windows form control by name (C# / VB)

  - by Alex

  Suppose I have a label control on a windows form called "UserName". How can I refer to that label programmatically using the label name? For example I can do: For each ctrl as Control in TabPage.Controls If ctrl.Name = "UserName" Then ' Do something End If Next This seems quite inefficient. I would like to do something like: TabPage.Controls("UserName").Text = "Something" I did some googling but couldn't find a satisfactory answer. Most suggested looping, some said .NET 2005 doesn't support direct refenece using string name, and FindControl method was asp.net only... EDIT Thanks for the response so far. Here is a bit more detail. I have a windows form with three tabpages, all of which a very similar in design and function i.e. same drop down menus, labels, react in simlar way to events etc. Rather than write code for each event per tabpage I have built a class that controls the events etc. per tabpage. For example, on each tabpage there is a Label called "RecordCounter" that simply shows the number of rows in the datagridview when it is populated by selection of a variable in a drop down menu. So what I want to be able to do is, upon selection of a variable in the drop down menu, the datagridview populates itself with data, and then I simply want to display the number of rows in a label ("RecordCounter"). This is exactly the same process on each tabpage so what I am doing is passing the tabpage to the class and then I want to be able to refer to the "RecordCounter" and then update it. In my class I set the ActivePage property to be the TabPage that the user has selected and then want to be able to do something like: ActivePage.RecordCounter.Text = GetNumberOfRows()

• Performance Problems with Django's F() Object

  - by JayhawksFan93

  Has anyone else noticed performance issues using Django's F() object? I am running Windows XP SP3 and developing against the Django trunk. A snippet of the models I'm using and the query I'm building are below. When I have the F() object in place, each call to a QuerySet method (e.g. filter, exclude, order_by, distinct, etc.) takes approximately 2 seconds, but when I comment out the F() clause the calls are sub-second. I had a co-worker test it on his Ubuntu machine, and he is not experiencing the same performance issues I am with the F() clause. Anyone else seeing this behavior? class Move (models.Model): state_meaning = models.CharField( max_length=16, db_index=True, blank=True, default='' ) drop = models.ForeignKey( Org, db_index=True, null=False, default=1, related_name='as_move_drop' ) class Split(models.Model): state_meaning = models.CharField( max_length=16, db_index=True, blank=True, default='' ) move = models.ForeignKey( Move, related_name='splits' ) pickup = models.ForeignKey( Org, db_index=True, null=False, default=1, related_name='as_split_pickup' ) pickup_date = models.DateField( null=True, default=None ) drop = models.ForeignKey( Org, db_index=True, null=False, default=1, related_name='as_split_drop' ) drop_date = models.DateField( null=True, default=None, db_index=True ) def get_splits(begin_date, end_date): qs = Split.objects \ .filter(state_meaning__in=['INPROGRESS','FULFILLED'], drop=F('move__drop'), # <<< the line in question pickup_date__lte=end_date) elapsed = timer.clock() - start print 'qs1 took %.3f' % elapsed start = timer.clock() qs = qs.filter(Q(drop_date__gte=begin_date) | Q(drop_date__isnull=True)) elapsed = timer.clock() - start print 'qs2 took %.3f' % elapsed start = timer.clock() qs = qs.exclude(move__state_meaning='UNFULFILLED') elapsed = timer.clock() - start print 'qs3 took %.3f' % elapsed start = timer.clock() qs = qs.order_by('pickup_date', 'drop_date') elapsed = timer.clock() - start print 'qs7 took %.3f' % elapsed start = timer.clock() qs = qs.distinct() elapsed = timer.clock() - start print 'qs8 took %.3f' % elapsed

• Tiny MCE (jquery plugin version) not showing toolbar in IE (works fine in other browsers)

  - by I am Wonder

  I had an implementation working well but for some reason IE decided it was tired of playing nice. I have an advanced implementation of TinyMCE (the jquery plugin version - see http://tinymce.moxiecode.com/examples/example_23.php for details). It still works great in all browsers but IE. In IE it shows the drop-down options for Format, Font family, and Font size, but only as text.. not as a drop down normally looks. All other buttons on the toolbar are missing. (I've tried IE8 and IE8 Compatibility Mode) I get a javascript error: Syntax error Line 36 Char 1. Unfortunately the javascript is being loaded dynamically so this doesn't help me. Here is my implementation code for the TinyMCE editor: $(function () { $('#InputStuffHere').tinymce({ // General options theme: "advanced", plugins: "safari,pagebreak,style,layer,table,save,advhr,advimage,advlink,inlinepopups,preview,media,searchreplace,contextmenu,paste,fullscreen,noneditable,visualchars,nonbreaking,template", // Theme options theme_advanced_buttons1: "bold,italic,underline,strikethrough,|,justifyleft,justifycenter,justifyright,justifyfull,formatselect,fontselect,fontsizeselect,|,hr,removeformat", theme_advanced_buttons2: "cut,copy,paste,pastetext,pasteword,|,search,replace,|,bullist,numlist,|,outdent,indent,blockquote,|,undo,redo,|,link,unlink,image,|,forecolor,backcolor,|,spellchecker", theme_advanced_buttons3 : "", theme_advanced_toolbar_location: "top", theme_advanced_toolbar_align: "left", theme_advanced_statusbar_location: "bottom", theme_advanced_resizing: true, // Drop lists for link/image/media/template dialogs template_external_list_url: "lists/template_list.js", external_link_list_url: "lists/link_list.js", external_image_list_url: "lists/image_list.js", media_external_list_url: "lists/media_list.js", //initialization callback init_instance_callback: "TinyMCEReady", add_form_submit_trigger : false }); }); So... anyone seen anything like this or have any ideas for me? Thank you so much everyone!

• jQuery ajax response not operating correctly

  - by mmarceau

  Ok this is frustrating... The code below works "correctly" as far as sending the email address to the SaveEmail URL and it gets saved correctly each time I change the drop down. However it only outputs the "Successful" message once, no matter how many times I change the value in the drop down. The "data" that is returned is "Successful". I would like to show the message for a couple seconds, then fade it out. It works correctly the first time I change the drop down, after that the change happens and the value gets saved, but the "Successful" message doesn't display. jQuery code: $('#AgentEmails').change(function() { var NewAddress = $('#AgentEmails').val(); $.post('SaveEmail.aspx', { email: NewAddress }, function(data) { $('#SelectMsg').html("<b>" + data + "</b>").fadeOut(); }); }); HTML code: <select ID='AgentEmails' runat='server'> <option value="[email protected]">TEST</option> </select><span id='SelectMsg'></span> What needs to be changed in my code to make this operate correctly? Thanks for the help.

• Have a clickable button on top of a combobox in WPF

  - by Travyguy9

  I can get a button to appear and be clickable in the drop down list of a combo box, but I cannot get the selected combo box item (the drop list is closed) to have the button be clickable. It always skips the button click and just opens the drop down list. I basically want the Button_Click event handler that I setup to be called once it is clicked. Here is my sample combo box that shows the button but is not clickable once it is in the selected item: <ComboBox x:Name="MyCombo" Width="200" Height="30" ItemsSource="{Binding ListCombo}"> <ComboBox.Resources> <DataTemplate DataType="{x:Type local:ComboItemClass}"> <StackPanel Orientation="Horizontal"> <TextBlock Text="{Binding Path=SampleText}" Width="120" /> <Button Width="20" Content="..." Click="Button_Click"/> </StackPanel> </DataTemplate> </ComboBox.Resources> </ComboBox>

• Using placeholders/variables in a sed command

  - by jesse_galley

  I want to store a specific part of a matched result as a variable to be used for replacement later. I would like to keep this in a one liner instead of finding the variable I need before hand. when configuring apache, and use mod_rewrite, you can specificy specific parts of patterns to be used as variables,like this: RewriteRule ^www.example.com/page/(.*)$ http://www.example.com/page.php?page=$1 [R=301,L] the part of the pattern match that's contained inside the parenthesis is stored as $1 for use later. So if the url was www.example.com/page/home, it would be replaced with www.example.com/page.php?page=home. So the "home" part of the match was saved in $1 because it was the part of the pattern inside the parenthesis. I want something like this functionality with a sed command, I need to automatically replace many strings in a SQL dump file, to add drop table if exist commands before each create table, but I need to know the table name to do this, so if the dump file contains something like: ... CREATE TABLE `orders` ... I need to run something like: cat dump.sql | sed "s/CREATE TABLE `(.*)`/DROP TABLE IF EXISTS $1\N CREATE TABLE `$1`/g" to get the result of: ... DROP TABLE IF EXISTS `orders` CREATE TABLE `orders` ... I'm using the mod_rewrite syntax in the sed command as a logical example of what I'm trying to do. Any suggestions?

• Are there any modern GUI toolkits which implement a heirarchical menu buffer zone?

  - by scomar

  In Bruce Tognazzini's quiz on Fitt's Law, the question discussing the bottleneck in the hierarchical menu (as used in almost every modern desktop UI), talks about his design for the original Mac: The bottleneck is the passage between the first-level menu and the second-level menu. Users first slide the mouse pointer down to the category menu item. Then, they must carefully slide the mouse directly across (horizontally) in order to move the pointer into the secondary menu. The engineer who originally designed hierarchicals apparently had his forearm mounted on a track so that he could move it perfectly in a horizontal direction without any vertical component. Most of us, however, have our forarms mounted on a pivot we like to call our elbow. That means that moving our hand describes an arc, rather than a straight line. Demanding that pivoted people move a mouse pointer along in a straight line horizontally is just wrong. We are naturally going to slip downward even as we try to slide sideways. When we are not allowed to slip downward, the menu we're after is going to slam shut just before we get there. The Windows folks tried to overcome the pivot problem with a hack: If they see the user move down into range of the next item on the primary menu, they don't instantly close the second-level menu. Instead, they leave it open for around a half second, so, if users are really quick, they can be inaccurate but still get into the second-level menu before it slams shut. Unfortunately, people's reactions to heightened chance of error is to slow down, rather than speed up, a well-established phenomenon. Therefore, few users will ever figure out that moving faster could solve their problem. Microsoft's solution is exactly wrong. When I specified the Mac hierarchical menu algorthm in the mid-'80s, I called for a buffer zone shaped like a <, so that users could make an increasingly-greater error as they neared the hierarchical without fear of jumping to an unwanted menu. As long as the user's pointer was moving a few pixels over for every one down, on average, the menu stayed open, no matter how slow they moved. (Cancelling was still really easy; just deliberately move up or down.) This just blew me away! Such a simple idea which would result in a huge improvement in usability. I'm sure I'm not the only one who regularly has the next level of a menu slam shut because I don't move the mouse pointer in a perfectly horizontal line. So my question is: Are there any modern UI toolkits which implement this brilliant idea of a < shaped buffer zone in hierarchical menus? And if not, why not?!

• Can't get network bridging to work

  - by Antonis Christofides

  I'm trying to make network bridging to work on a Debian squeeze (I'm experimenting in order to make a QEMU/KVM virtual machine that will be visible to the outside network as if it were a distinct machine). The problem is that when I type brctl addif br0 eth0 then I lose connectivity to the network until I type brctl delif br0 eth0. More specifically, here's how my machine looks like before I do anything (essentially eth0 is listening on 147.102.160.153): root@laura:/home/anthony# ip addr show 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 8c:73:6e:db:1c:1b brd ff:ff:ff:ff:ff:ff inet 147.102.160.153/24 brd 147.102.160.255 scope global eth0 inet6 2001:648:2000:a0:8e73:6eff:fedb:1c1b/64 scope global dynamic valid_lft 2591848sec preferred_lft 604648sec inet6 fe80::8e73:6eff:fedb:1c1b/64 scope link valid_lft forever preferred_lft forever 3: wlan0: <BROADCAST,MULTICAST> mtu 1500 qdisc mq state DOWN qlen 1000 link/ether 4c:ed:de:8e:44:d7 brd ff:ff:ff:ff:ff:ff 4: vboxnet0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000 link/ether 0a:00:27:00:00:00 brd ff:ff:ff:ff:ff:ff 5: pan0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN link/ether ee:7c:88:59:d0:e8 brd ff:ff:ff:ff:ff:ff Now let me add the bridge: root@laura:/home/anthony# brctl addbr br0 root@laura:/home/anthony# ip tuntap add dev tap0 mode tap root@laura:/home/anthony# ip link set tap0 up root@laura:/home/anthony# brctl addif br0 tap0 Until here everything continues to work normally. Finally, I try to add eth0 to the bridge: root@laura:/home/anthony# brctl addif br0 eth0 At this point, I no longer have a network connection. If I try to ping something, it tells "Destination Host Unreachable". The output of ip addr show seems normal: root@laura:/home/anthony# ip addr show 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 8c:73:6e:db:1c:1b brd ff:ff:ff:ff:ff:ff inet 147.102.160.153/24 brd 147.102.160.255 scope global eth0 inet6 2001:648:2000:a0:8e73:6eff:fedb:1c1b/64 scope global dynamic valid_lft 2591908sec preferred_lft 604708sec inet6 fe80::8e73:6eff:fedb:1c1b/64 scope link valid_lft forever preferred_lft forever [snip wlan0, vboxnet0 and pan0, which are down and irrelevant] 8: br0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN link/ether 16:30:f2:67:ab:75 brd ff:ff:ff:ff:ff:ff 9: tap0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 500 link/ether 16:30:f2:67:ab:75 brd ff:ff:ff:ff:ff:ff inet6 fe80::1430:f2ff:fe67:ab75/64 scope link valid_lft forever preferred_lft forever Also: root@laura:/home/anthony# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 147.102.160.0 0.0.0.0 255.255.255.0 U 1 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 eth0 0.0.0.0 147.102.160.200 0.0.0.0 UG 0 0 0 eth0 I can't understand what I'm doing wrong. I want the machine to continue to listen on 147.102.160.153 on eth0, and in addition to that I want to have a tap0 interface, bridged to eth0, that will be available to the guest machine so that the latter listens on another ip address (say 147.102.160.205). (If there's another way to achieve what I want, I'm also interested.)

• Neighbour table overflow on Linux hosts related to bridging and ipv6

  - by tim

  Note: I already have a workaround for this problem (as described below) so this is only a "want-to-know" question. I have a productive setup with around 50 hosts including blades running xen 4 and equallogics providing iscsi. All xen dom0s are almost plain Debian 5. The setup includes several bridges on every dom0 to support xen bridged networking. In total there are between 5 and 12 bridges on each dom0 servicing one vlan each. None of the hosts has routing enabled. At one point in time we moved one of the machines to a new hardware including a raid controller and so we installed an upstream 3.0.22/x86_64 kernel with xen patches. All other machines run debian xen-dom0-kernel. Since then we noticed on all hosts in the setup the following errors every ~2 minutes: [55888.881994] __ratelimit: 908 callbacks suppressed [55888.882221] Neighbour table overflow. [55888.882476] Neighbour table overflow. [55888.882732] Neighbour table overflow. [55888.883050] Neighbour table overflow. [55888.883307] Neighbour table overflow. [55888.883562] Neighbour table overflow. [55888.883859] Neighbour table overflow. [55888.884118] Neighbour table overflow. [55888.884373] Neighbour table overflow. [55888.884666] Neighbour table overflow. The arp table (arp -n) never showed more than around 20 entries on every machine. We tried the obvious tweaks and raised the /proc/sys/net/ipv4/neigh/default/gc_thresh* values. FInally to 16384 entries but no effect. Not even the interval of ~2 minutes changed which lead me to the conclusion that this is totally unrelated. tcpdump showed no uncommon ipv4 traffic on any interface. The only interesting finding from tcpdump were ipv6 packets bursting in like: 14:33:13.137668 IP6 fe80::216:3eff:fe1d:9d01 > ff02::1:ff1d:9d01: HBH ICMP6, multicast listener reportmax resp delay: 0 addr: ff02::1:ff1d:9d01, length 24 14:33:13.138061 IP6 fe80::216:3eff:fe1d:a8c1 > ff02::1:ff1d:a8c1: HBH ICMP6, multicast listener reportmax resp delay: 0 addr: ff02::1:ff1d:a8c1, length 24 14:33:13.138619 IP6 fe80::216:3eff:fe1d:bf81 > ff02::1:ff1d:bf81: HBH ICMP6, multicast listener reportmax resp delay: 0 addr: ff02::1:ff1d:bf81, length 24 14:33:13.138974 IP6 fe80::216:3eff:fe1d:eb41 > ff02::1:ff1d:eb41: HBH ICMP6, multicast listener reportmax resp delay: 0 addr: ff02::1:ff1d:eb41, length 24 which placed the idea in my mind that the problem maybe related to ipv6, since we have no ipv6 services in this setup. The only other hint was the coincidence of the host upgrade with the beginning of the problems. I powered down the host in question and the errors were gone. Then I subsequently took down the bridges on the host and when i took down (ifconfig down) one particularly bridge: br-vlan2159 Link encap:Ethernet HWaddr 00:26:b9:fb:16:2c inet6 addr: fe80::226:b9ff:fefb:162c/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:120 errors:0 dropped:0 overruns:0 frame:0 TX packets:9 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:5286 (5.1 KiB) TX bytes:726 (726.0 B) eth0.2159 Link encap:Ethernet HWaddr 00:26:b9:fb:16:2c inet6 addr: fe80::226:b9ff:fefb:162c/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1801 errors:0 dropped:0 overruns:0 frame:0 TX packets:20 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:126228 (123.2 KiB) TX bytes:1464 (1.4 KiB) bridge name bridge id STP enabled interfaces ... br-vlan2158 8000.0026b9fb162c no eth0.2158 br-vlan2159 8000.0026b9fb162c no eth0.2159 The errors went away again. As you can see the bridge holds no ipv4 address and it's only member is eth0.2159 so no traffic should cross it. Bridge and interface .2159 / .2157 / .2158 which are in all aspects identical apart from the vlan they are connected to had no effect when taken down. Now I disabled ipv6 on the entire host via sysctl net.ipv6.conf.all.disable_ipv6 and rebooted. After this even with bridge br-vlan2159 enabled no errors occur. Any ideas are welcome.

• SQLAuthority News – Windows Efficiency Tricks and Tips – Personal Technology Tip

  - by pinaldave

  This is the second post in my series about my favorite Technology Tips, and I wanted to focus on my favorite Microsoft product.  Choosing just one topic to cover was too hard, though.  There are so many interesting things I have to share that I am forced to turn this second installment into a five-part post.  My five favorite Windows tips and tricks. 1) You can open multiple applications using the task bar. With the new Windows 7 taskbar, you can start navigating with just one click.  For example, you can launch Word by clicking on the icon on your taskbar, and if you are using multiple different programs at the same time, you can simply click on the icon to return to Word.  However, what if you need to open another Word document, or begin a new one?  Clicking on the Word icon is just going to bring you back to your original program.  Just click on the Word icon again while holding down the shift key, and you’ll open up a new document. 2) Navigate the screen with the touch of a button – and not your mouse button. Yes, we live in a pampered age.  We have access to amazing technology, and it just gets better every year.  But have you ever found yourself wishing that right when you were in the middle of something, you didn’t have to interrupt your work flow be reaching for your mouse to navigate through the screen?  Yes, we have all been guilty of this pampered wish.  But Windows has delivered!  Now you can move your application window using your arrow keys. Lock the window to the left, right hand screen: Win+left Arrow and Win+right Arrow Maximize & minimize: Win+up arrow and Win+down arrow Minimize all items on screen: Win+M Return to your original folder, or browse through all open windows: Alt+up arrow, Alt+Left Arrow, or Alt+right arrow Close down or reopen all windows: win+home 3) Are you one of the few people who still uses Command Prompt? You know who you are, and you aren’t ashamed to still use this option that so many people have forgotten about it.  You can easily access it by holding down the shift key while RIGHT clicking on any folder. 4) Quickly select multiple files without using your mouse. We all know how to select multiple files or folders by Ctrl-clicking or Shift-clicking multiple items.  But all of us have tried this, and then accidentally released Ctrl, only to lose all our precious work.  Now there is a way to select only the files you want through a check box system.  First, go to Windows Explorer, click Organize, and then “Folder and Search Options.”  Go to the View tab, and under advanced settings, you can find a box that says “Use check boxes to select items.”  Once this has been selected, you will be able to hover your mouse over any file and a check box will appear.  This makes selecting multiple, random files quick and easy. 5) Make more out of remote access. If you work anywhere in the tech field, you are probably the go-to for computer help with friends and family, and you know the usefulness of remote access (ok, some of us use this extensively at work, as well, but we all have friends and family who rely on our skills!).  Often it is necessary to restart a computer, which is impossible in remote access as the computer will not show the shutdown menu.  To force the computer to do your wishes, we return to Command Prompt.  Open Command Prompt and type “shutdown /s” for shutdown, or “shutdown /r” for restart. I hope you will find above five tricks which I use in my daily use very important.

• The Power of Goals

  - by BuckWoody

  Every year we read blogs, articles, magazines, hear news stories and blurbs on making New Year’s Resolutions. Well, I for one don’t do that. I do something else. Each year, on January 1, my wife, daughter and I get up early - like before 6:00 A.M. - and find a breakfast place that’s open. When I used to live in Safety Harbor, Florida, that was the “Paradise Café”, which has some of the best waffles around…but I digress. We find that restaurant and have a great breakfast while everyone else is recuperating from the night before. And we bring along a worn leather book that we’ve been writing in since my daughter wasn’t even old enough to read. It’s our book of Goals. A resolution, as it is purely defined, is a decision to change, stop or start an action. It has a sense of continuance, and that’s the issue. Some people decide things like “I’m going to lose weight” or “I’m going to spend more time with my family or hobby”. But a goal is different. A goal tends to have a defined start and end point. It’s something that can be measured. So each year on January 1 we sit down with the little leather book and we make a few - and only a few - individual and family goals. Sometimes it’s to exercise three times a week at the gym, sometimes it’s to save a certain percentage of income, and sometimes it’s to give away some of our possessions or to help someone we know in a specific way. Each person is responsible for their own goals - coming up with them, and coming up with a plan to meet them. Then we write it down in the little leather book. But it doesn’t end there. Each month, we grab the little leather book and read out the goals from that year to each person with a question or two: How are you doing on your goal? And what are you doing about reaching it? Can I help? Am I helping? At the end of the year, we put a checkmark by the goals we reached, and an X by the ones we didn’t. There’s no judgment, there’s no statements, each person is just expected to handle the success or failure in their own way. We also have family goals, and those we work on together. This might seem a little “corny” to some people. “I don’t need to write goals down” they say, “I keep track in my head of the things I do all the time. That’s silly.” But let me give you a little challenge: find a book, get with your family, and write down the things you want to do by the next January 1. Each month, look at the book. You can make goals for your career, your education, your spiritual side, your family, whatever. But if you make your goals realistic, think them through, and think about how you will achieve them, you will be surprised by the power of written goals.

• Ask HTG: How Can I Check the Age of My Windows Installation?

  - by Jason Fitzpatrick

  Curious about when you installed Windows and how long you’ve been chugging along without a system refresh? Read on as we show you a simple way to see how long-in-the-tooth your Windows installation is. Dear How-To Geek, It feels like it has been forever since I installed Windows 7 and I’m starting to wonder if some of the performance issues I’m experiencing have something to do with how long ago it was installed. It isn’t crashing or anything horrible, mind you, it just feels slower than it used to and I’m wondering if I should reinstall it to wipe the slate clean. Is there a simple way to determine the original installation date of Windows on its host machine? Sincerely, Worried in Windows Although you only intended to ask one question, you actually asked two. Your direct question is an easy one to answer (how to check the Windows installation date). The indirect question is, however, a little trickier (if you need to reinstall Windows to get a performance boost). Let’s start off with the easy one: how to check your installation date. Windows includes a handy little application just for the purposes of pulling up system information like the installation date, among other things. Open the Start Menu and type cmd in the run box (or, alternatively, press WinKey+R to pull up the run dialog and enter the same command). At the command prompt, type systeminfo.exe Give the application a moment to run; it takes around 15-20 seconds to gather all the data. You’ll most likely need to scroll back up in the console window to find the section at the top that lists operating system stats. What you care about is Original Install Date: We’ve been running the machine we tested the command on since August 23 2009. For the curious, that’s one month and a day after the initial public release of Windows 7 (after we were done playing with early test releases and spent a month mucking around in the guts of Windows 7 to report on features and flaws, we ran a new clean installation and kept on trucking). Now, you might be asking yourself: Why haven’t they reinstalled Windows in all that time? Haven’t things slowed down? Haven’t they upgraded hardware? The truth of the matter is, in most cases there’s no need to completely wipe your computer and start from scratch to resolve issues with Windows and, if you don’t bog your system down with unnecessary and poorly written software, things keep humming along. In fact, we even migrated this machine from a traditional mechanical hard drive to a newer solid-state drive back in 2011. Even though we’ve tested piles of software since then, the machine is still rather clean because 99% of that testing happened in a virtual machine. That’s not just a trick for technology bloggers, either, virtualizing is a handy trick for anyone who wants to run a rock solid base OS and avoid the bog-down-and-then-refresh cycle that can plague a heavily used machine. So while it might be the case that you’ve been running Windows 7 for years and heavy software installation and use has bogged your system down to the point a refresh is in order, we’d strongly suggest reading over the following How-To Geek guides to see if you can’t wrangle the machine into shape without a total wipe (and, if you can’t, at least you’ll be in a better position to keep the refreshed machine light and zippy): HTG Explains: Do You Really Need to Regularly Reinstall Windows? PC Cleaning Apps are a Scam: Here’s Why (and How to Speed Up Your PC) The Best Tips for Speeding Up Your Windows PC Beginner Geek: How to Reinstall Windows on Your Computer Everything You Need to Know About Refreshing and Resetting Your Windows 8 PC Armed with a little knowledge, you too can keep a computer humming along until the next iteration of Windows comes along (and beyond) without the hassle of reinstalling Windows and all your apps.

• How to Speed Up Any Android Phone By Disabling Animations

  - by Chris Hoffman

  Android phones — and tablets, too — display animations when moving between apps and screens. These animations look very slick, but they waste time — especially on fast phones, which could switch between apps instantly if not for the animations. Disabling these animations will speed up navigating between different apps and interface screens on your phone, saving you time. You can also speed up the animations if you’d rather see them. Access the Developer Options Menu First, we’ll need to access the Developer Options menu. It’s hidden by default so Android users won’t stumble across it unless they’re actually looking for it. To access the Developer Options menu, open the Settings screen, scroll down to the bottom of the list, and tap the About phone or About tablet option. Scroll down to the Build number field and tap it repeatedly. Eventually, you’ll see a message appear saying “You are now a developer!”. The Developer options submenu now appears on the Settings screen. You’ll find it near the bottom of the list, just above the About phone or About tablet option. Disable Interface Animations Open the Developer Options screen and slide the switch at the top of the screen to On. This allows you to change the hidden options on this screen. If you ever want to re-enable the animations and revert your changes, all you have to do is slide the Developer Options switch back to Off. Scroll down to the Drawing section. You’ll find the three options we want here — Window animation scale, Transition animation scale, and Animator duration scale. Tap each option and set it to Animation off to disable the associated animations. If you’d like to speed up the animations without disabling them entirely, select the Animation .5x option instead. If you’re feeling really crazy, you can even select longer animation durations. You can make the animations take as much as ten times longer with the Animation 10x setting. The Animator duration scale option applies to the transition animation that appears when you tap the app drawer button on your home screen.  Your change here won’t take effect immediately — you’ll have to restart Android’s launcher after changing the Animator duration scale setting. To restart Android’s launcher, open the Settings screen, tap Apps, swipe over to the All category, scroll down, and tap the Launcher app. Tap the Force stop button to forcibly close the launcher, then tap your device’s home button to re-launch the launcher. Your app drawer will now open immediately, too. Now whenever you open an app or transition to a new screen, it will pop up as quickly as possible — no waiting for animations and wasting processing power rendering them. How much of a speed improvement you’ll see here depends on your Android device and how fast it is. On our Nexus 4, this change makes many apps appear and become usable instantly if they’re running in the background. If you have a slower device, you may have to wait a moment for apps to be usable. That’s one of the big reasons why Android and other operating systems use animations. Animations help paper over delays that can occur while the operating system loads the app.

• Z axis trouble with glTranslatef(...) - LWJGL

  - by Zarkopafilis

  Here is the code: private static boolean up = true , down = false , left = false , right = false, reset = false, in = false , out = false; public void start() { try { Display.setDisplayMode(new DisplayMode(800,600)); Display.create(); } catch (LWJGLException e) { e.printStackTrace(); System.exit(0); } GL11.glMatrixMode(GL11.GL_PROJECTION); GL11.glLoadIdentity(); GL11.glOrtho(0, 800, 0, 600, 0.00001f, 1000); GL11.glMatrixMode(GL11.GL_MODELVIEW); Keyboard.enableRepeatEvents(true); while (!Display.isCloseRequested()) { GL11.glClear(GL11.GL_COLOR_BUFFER_BIT); input(); if(up){ GL11.glTranslatef(0,0.1f,0); } if(down){ GL11.glTranslatef(0,-0.1f,0); } if(left){ GL11.glTranslatef(-0.1f,0,0); } if(right){ GL11.glTranslatef(0.1f,0,0); } if(in){ GL11.glTranslatef(0, 0, 1f); } if(out){ GL11.glTranslatef(0, 0, -1f); } if(reset){ GL11.glLoadIdentity(); } GL11.glBegin(GL11.GL_QUADS); GL11.glColor3f(255, 255, 255); GL11.glVertex3f(800/2, 600/2, 0); GL11.glVertex3f(800/2 + 200, 600/2, 0); GL11.glVertex3f(800/2 + 200, 600/2 + 200, 0); GL11.glVertex3f(800/2, 600/2 + 200, 0); GL11.glColor3f(0, 255, 0); GL11.glVertex3f(800/2, 600/2, 1); GL11.glVertex3f(800/2 + 200, 600/2, 1); GL11.glVertex3f(800/2 + 200, 600/2 + 200, 1); GL11.glVertex3f(800/2, 600/2 + 200, 1); GL11.glEnd(); Display.update(); } Display.destroy(); } public static void main(String[] argv){ new main().start(); } public void input(){ up = false; down = false; left = false; right = false; reset = false; in = false; out = false; if(Keyboard.isKeyDown(Keyboard.KEY_SPACE)){ reset = true; } if(Keyboard.isKeyDown(Keyboard.KEY_W)){ up = true; } if(Keyboard.isKeyDown(Keyboard.KEY_S)){ down = true; } if(Keyboard.isKeyDown(Keyboard.KEY_A)){ left = true; } if(Keyboard.isKeyDown(Keyboard.KEY_D)){ right = true; } if(Keyboard.isKeyDown(Keyboard.KEY_Q)){ in = true; } if(Keyboard.isKeyDown(Keyboard.KEY_E)){ out = true; } } As you can see I am creating 2 quads , a white one at z 0 and a green one at z 1. WASD keys function correctly. Also when I hit SPACEBAR the white quad is being shown. If I then press E , I can see the green quad. But if I press Q afterwards , I dont see the white one again!(Space Works everytime). Also if I render the green one at Z = -1 everything works perfectly BUT you may need up to 3 key presses Q/E to see the other quad. Why is that happening?
