• Cannot assign port 4 to WAN on TP-Link WR740N by DD-WRT wiki

  - by Victor Sergienko

  I'm following the DD-WRT instruction to get TP-Link WR740N v3's Port 4 on a different VLAN, but this doesn't happen. First, I have no "Setup VLANs" settinngs tab in DD-WRT v24-sp2 (07/20/12) std r19519. I can get Internet on Wi-Fi if assigning eth1 to "WAN Port", but then all Ethernet ports get on the same VLAN and any wired connection grabs the DHCP address and Internet connection from router. When following the "old" instruction, if I run, say, nvram set vlan2ports="2 5*", should there appear a new interface, vlan2, in ifconfig, after ifconfig vlan2 up? It doesn't - does it mean there is no support for different VLANs in my software/hardware? What am I missing? Is it impossible to create more VLANs on TP-Link740?

• Web based console connections not working in Windows 7 posted: Jan 20, 2010 8:55 AM

  - by nmeth

  For slightly complicated reasons we tend to give people console access to VMs via the webui. This has worked fine in the past, however when the users update their client machines to Windows 7 (or Vista, I am told, although I have not tested that), then the console fails to work. On IE8, having allowed the ActiveX control, the tab causes a "Internet Explorer has stopped working" dialog. On Firefox 3.5 , once the plugin has been installed, using the console causes the browser to crash. I've updated to the most recent VC 2.5 release, and ESX 3.5u5. Anyone else seeing this? Any clues how to get round it (other than using the fat client). Nigel.

• Network backup for Macs and PCs - formatting question

  - by neilfein

  I'm trying to use a LaCie 2TB drive as an AirPort drive, for backup on a home network. We have one mac and two PC laptops. My plan is to create a Mac partition and a Windows partition. However, Disk Utility won't let me set the windows partition to Windows format; there's no option in the menu for it in the partition tab. Am I doing something wrong? Alternatively, is there a way to partition the drive with one partition that all three machines can see? We have a Mac G5 with 10.4 and two laptops with Windows 7. Thanks!

• Is there a way to iterate over all open windows in Mac OS X?

  - by Alex

  When you unplug an external monitor with a higher resolution that your macbook from your laptop, the windows mostly retain their width, but their size gets clipped to the (smaller) height of the macbook screen. When you plug the monitor back in, their size remains frustratingly small. My question is: is there any way that I can iterate over all open windows, save their size, and restore them once the monitor gets plugged in again?

• Links opened by left-click in IE8 take forever compared to middle-mouse button

  - by Bigbio2002

  When I use the middle mouse button to open a link in a new tab, it works instantly. However, if I left-click the link to open it normally, IE8 freezes for about 5 seconds before the popup window opens. I'm sick of all the slowness and the glitchiness and the memory hogging, and I just want it to work as well as all the other browsers out there. Anybody else experiencing this and have any tips? Note: It's not the Java SSV helper or the Skype addon (because I have those disabled). I'm looking for some advanced solutions that I can try. (God, I hate IE8, but I'm a loyal Microsoft follower so I refuse to switch to Firefox. )

• How do I maximize a window in one monitor and do other things on the other monitor

  - by RoboShop

  Hi, I have windows 7 installed on my laptop which is a Dell studio XPS 16. I recently set up a second monitor for it. I've noticed that when I load up "full maximisation" applications (I don't know the term) like a game or media center on one monitor, I can't seem to do anything with the other monitor. With the game, I can see the other monitor, I can play a movie on it even, but if I click the mouse button on it, it'll stop the game and alt-tab away. In Media Center, I can't even cross my mouse over the other monitor. So my question is, in Windows 7, is it possible to run programs like this that are designed to be run in one maximised window and still be able to do things on the other window?

• Is there a terminal that features sliding like guake and screen spliting like terminator on Linux?

  - by e-satis

  Sliding means I got the terminal always in background and I can call it with a shortcut, and it will slide down from the top of the screen like in Quake (which why the most known terminal implementing it is called guake). Splitting terminal means I can seen in one terminal tab several shells, like with screen or tmux. But I can also take the focus on each part of the terminal by clicking on it, not just with a 4 keys keyboard shortcut. Which terminator let me do. Is there a terminal that features both on Linux ? Even something I can pay for.

• Why does my CPU Usage reach 100% too often?

  - by deathlock

  I'm using a dual-core processor and often see my CPU usage reaches 100%. I realize this may happen if I'm running too much applications, so when I know the computer starts to run slowly, I start to close my applications. I usually run 4-5 applications simultaneously. Usually those are: web browser (Google Chrome), Adobe Photoshop, Notepad++, XAMPP, and Windows Task Manager. Usually I close tabs in my Chrome first, because I often browse the net with about 20 tabs/4 windows open, so I presume that would take much memory (bad habit, I know). But even after closing Chrome's tabs or closing other applications, my CPU Usage often stays at high percentage - 72% at best, 100% at worst. I check the Processes tab on Windows Task Manager and usually found the System, System Idle Process, or services.exe taking the highest CPU process (could reach 60). Why is this happening? And is there any solution? EDIT I have T2250 @ 1,73 Ghz and 2.5 GB RAM

• Git completion with aliases

  - by cormacrelf

  I have a convenient dotfiles repo on Github for you all to look at, here. FYI, git is installed via Homebrew, as with most of the executables on my system. My git-completion in zsh works fine when I use no aliases, such as: % git add fi<TAB> # => file.rb But if I add an alias in my .zshrc (actually cormacrelf-dotfiles-repo/zsh/aliases.zsh), like: alias ga="git add" compdef _git ga=git-add ... trying to complete anything (not just files: branches, etc.) results in an error: % git add fi _git:19: parse error: condition expected: 1

• SQL Server Configuration Manager menu won't show up

  - by Aurelien Gasser

  I'm running a Windows 8 VM on a MacBook using Parallels Desktop 9. On this Windows VM, I have a SQL Server instance running perfectly. However, when I launch SQL Server Configuration Manager, and I want to enable an IP configuration, the Enable menu options are invisible : Here is a screenshot : http://i.imgur.com/PY7qGup.png (I don't have enough reputation to display the image inline) When I click the arrow, a contextual menu should appear with 2 choices "Yes" or "No". Instead, a tiny contextual menu appears, but it's empty. I tried using my keyboard tab/space/arrows keys without success. Has anyone faced/solved the same problem ?

• 3 Dimensional Array

  - by George Johnston

  I don't know why I'm experiencing so much trouble with this, but I would like to have an array that basically represents a layer number and x,y coordinates so I could essentially say, int i = array[layer,x,y] and get the corrisponding value per layer. I create the array.. int[,,] myarray ...initialize it myarray = new int[0,width, height]; ...and it blows up when try and grab a value. int n = myarray[0,1,1] What am I missing?

• CSS Margin problem

  - by amitairos

  I'm starting out in HTML and CSS. I have a div element on the page, which doesn't fill the whole page. In it- there's a ul element and some list items in it. I want to put the list 227px from the top of the div element, but I can't manage to accomplish this- it pushes it more. Also- between the list items I want a margin of 40 pixels, but it also does more. What's the problem? Here's my code: Html: <body> <div class="Hashta"> <div class="Menu"> <ul id="MenuItems"> <li><a href="#" >ONE</a></li> <li><a href="#" >TWO</a></li> <li><a href="#" >THREE</a></li> <li><a href="#" >FOUR</a></li> </ul> </div> </div> </body> CSS: body { background-color: Gray; } .Hashta{ width:874px; height:650px; background-color:black; margin: auto auto 50px auto; border-radius: 20px; border: 3px solid darkgray; moz-box-shadow: 2px 2px 10px black; webkit-box-shadow: 2px 2px 10px black; box-shadow: 2px 2px 10px black; } .Menu { margin-top: 227px; padding-right: 50px; float:right; } #MenuItems { list-style:none; } #MenuItems li { text-align:center; position:relative; padding: 4px 10px 4px 10px; margin-right:30px; margin-bottom: 40px; border:none; } #MenuItems li a{ width: 280px; height: 70px; background-color: green; color:White; font-family:Arial, Helvetica, sans-serif; font-size:24px; display:block; outline:0; text-decoration:none; text-shadow: 1px 1px 1px #000; line-height: 70px; } If you want to measure the pixels- you can install this: http://www.mioplanet.com/products/pixelruler/ (click to rotate) Thanks!

• Windows 2003-R2-Server: Process "System" takes large chunks of CPU time

  - by Dabu

  I have a domain controller running 2003 R2. The server behaves very well when restarted daily, however, each day it is not restarted, there's a process called "System" that takes enourmous chunks of CPU time (up to 95%). The server supports AD, WINS, DNS, has Kaspersky Endpoint Security running, and manages backups via Arcserve 15. When I tried so far: Process Explorer (ex-Sysinternals) shows that the "System" process has no sub-processes. In the "Threads" tab of the detailled view I can see that 90% of the CPU time is used up by "ntkrnlpa.exe+0x803c0". The "Interrupts" process is running at 3-5% of CPU time, I'm not sure if this accounts for the amount of CPU time that System takes.

• Conflict between some JavaScript and jQuery on same page

  - by hollyb

  I am using a JavaScript function and some jQuery to perform two actions on a page. The first is a simple JS function to hide/show divs and change the active state of a tab: This is the JS that show/hides divs and changes the active state on some tabs: var ids=new Array('section1','section2','section3'); function switchid(id, el){ hideallids(); showdiv(id); var li = el.parentNode.parentNode.childNodes[0]; while (li) { if (!li.tagName || li.tagName.toLowerCase() != "li") li = li.nextSibling; // skip the text node if (li) { li.className = ""; li = li.nextSibling; } } el.parentNode.className = "active"; } function hideallids(){ //loop through the array and hide each element by id for (var i=0;i<ids.length;i++){ hidediv(ids[i]); } } function hidediv(id) { //safe function to hide an element with a specified id document.getElementById(id).style.display = 'none'; } function showdiv(id) { //safe function to show an element with a specified id document.getElementById(id).style.display = 'block'; } The html: <ul> <li class="active"><a onclick="switchid('section1', this);return false;">ONE</a></li> <li><a onclick="switchid('section2', this);return false;">TWO</a></li> <li><a onclick="switchid('section3', this);return false;">THREE</a></li> </ul> <div id="section1" style="display:block;">TEST</div> <div id="section2" style="display:none;">TEST 2</div> <div id="section3" style="display:none;">TEST 3</div> Now the problem.... I've added the jQuery image gallery called galleria to one of the tabs. The gallery works great when it resides in the div that is intially set to display:block. However, when it is in one of the divs that is set to display: none; part of the gallery doesn't work when the div is toggled to be visible. Specifically, the following css ceases to be written (this is created by galleria jQuery): element.style { display:block; height:50px; margin-left:-17px; width:auto; } For the life of me, I can't figure out why the gallery fails when it's div is set to display: none. Since this declaration is overwritten when a tab is clicked (via the Javascript functions above), why would this cause a problem? As I mentioned, it works perfectly when it lives the in display: block; div. Any ideas? I don't expect anybody to be familiar with the jQuery galleria image gallery... but perhaps an idea of how one might repair this problem? Thanks!

• Create a Color Picker, similar to Photoshop's, using Javascript and HTML Canvas

  - by André Alçada Padez

  I am not at all versed in Computer Graphics and am in need of creating a color picker as a javascript tool to embed in an HTML page. First, and looking at Photoshop's one, i thought of the RGB palette as a three-dimensional matrix. My first attempt envolved: <script type="text/javascript"> var rgCanvas = document.createElement('canvas'); rgCanvas.width = 256; rgCanvas.height = 256; rgCanvas.style.border = '3px solid black'; for (g = 0; g < 256; g++){ for (r = 0; r < 256; r++){ var context = rgCanvas.getContext('2d'); context.beginPath(); context.moveTo(r,g); context.strokeStyle = 'rgb(' + r + ', ' + g + ', 0)'; context.lineTo(r+1,g+1); context.stroke(); context.closePath(); } } var bCanvas = document.createElement('canvas'); bCanvas.width = 20; bCanvas.height = 256; bCanvas.style.border = '3px solid black'; for (b = 0; b < 256; b++){ var context = bCanvas.getContext('2d'); context.beginPath(); context.moveTo(0,b); context.strokeStyle = 'rgb(' + 0 + ', ' + 0 + ', ' + b + ')'; context.lineTo(20, b); context.stroke(); context.closePath(); } document.body.appendChild(rgCanvas); document.body.appendChild(bCanvas); </script> this results in something like My thought is this is too linear, comparing to the ones i see in Photoshop and on the web. I would like to know the logic behind the color mapping in a picker like this: I don't really need the algorythms itself, i'm mainly trying to understand the logic. Thanks

• Getting molly-guard to work with sudo

  - by 0xC0000022L

  The program molly-guard is a brilliant little tool which will prompt you for a piece of information before you reboot or shut down a system. Usually it asks for the hostname. So when you work a lot via SSH, you won't end up taking down the wrong server, just because you were in the wrong tab or window. Now, this works all fine when you say reboot on the command line while you are already root. However, it won't work if you do sudo reboot (i.e. it won't even ask). How can I get it to work with sudo as well? System: Raspbian (latest, including updates), package molly-guard version 0.4.5-1.

• Quickly translate a word from English

  - by licorna

  I'm always reading English, but I'm a Spanish native speaker (I'm working on my thesis). Sometimes I need to translate a word into Spanish, and what I do now is to open a new tab and go to Google Translate and then put the word into the input field. Just a quick translation, one word or a small phrase. I'm a Mac and Firefox user. Is there a better way to achieve this? I was thinking that maybe a dashboard widget would do the trick and I was looking for one. The other option is to install the Google Toolbar, but I really hate toolbars. I don't know, a good Firefox extension maybe?
