  • Google analytics set up with wrong domain

    - by Tom
    I have recently embedded Google Analytics into a site using the default embed code. <script> (function (i, s, o, g, r, a, m) { i['GoogleAnalyticsObject'] = r; i[r] = i[r] || function () { (i[r].q = i[r].q || []).push(arguments) }, i[r].l = 1 * new Date(); a = s.createElement(o), m = s.getElementsByTagName(o)[0]; a.async = 1; a.src = g; m.parentNode.insertBefore(a, m) })(window, document, 'script', '//www.google-analytics.com/analytics.js', 'ga'); ga('create', 'UA-XXXXXXXX-1', 'MYDOMAIN.COM'); ga('send', 'pageview'); </script> However I had MYDOMAIN.COM set to an incorrect domain. The views for the site seem very low, however, I can see myself there as a visitor in the real time scanner. What effect would setting the domain incorrectly have had? How does Google use this parameter?

  • How to fix the boot set up?

    - by Chris
    I got two OSes in my PC, Ubuntu and Windows 7. Until yesterday Windows 7 was on top of my dual-boot menu list, but I wanted to change it, so I went inside Windows configurations and put Ubuntu first, but I also set the time to 0 because I thought I could access Windows through Grub. But what happens is that after I upgraded Ubuntu to 11.10, that screen with boot options don't show Windows 7 anymore. I went online searching for a solution to my problem, most of them told me to configure some Grub options and others to use programs to do it. I've done them all and still can't access Windows 7. Just in case my problem is not clear yet, this is how was my boot order before I messed it all up: Windows 7 Ubuntu with a time of 10 secs to choose between both. This is how I wanted it to be: Ubuntu Windows 7 with 0 time to choose, but, inside Ubuntu I could access Windows through that Grub screen. But this is what happens: Ubuntu Windows 7 0 time, so it don't let me choose anything and jumps inside Ubuntu then inside Ubuntu grub doesn't show up anymore (black screen) and it starts Ubuntu normally. I tried to fix this many times from different ways inside Ubuntu but nothing worked, also when I try do something and then upgrade my grub with sudo upgrade-grub it shows this message: Generating grub.cfg ... Found Windows 7 (loader) on /dev/sda1 Skipping Windows 7 (loader) on Wubi system Found linux image: /boot/vmlinuz-3.0.0-12-generic Found initrd image: /boot/initrd.img-3.0.0-12-generic Found linux image: /boot/vmlinuz-2.6.38-12-generic Found initrd image: /boot/initrd.img-2.6.38-12-generic done Thats why in the title I said it could probably be my WUBI messing all up. Anyone heave a solution for this? Do you need more information? I have a netbook so I cannot use the Windows Repair CD.

  • Ubuntu 12.04 Network Manager: unable to save manual setting to set up a static ip

    - by Andy
    I am fairly familiar with setting up servers, and ubuntu is generally my flavor of choice, but I just installed 12.04 desktop and I am seeing some behavior in network manager that is really puzzling. The network connection works fine if I leave it set on dhcp, but I would like a static IP address for my new web server. When I go into network manager and edit the connection for the one and only NIC I can select MANUAL from the dropdown menu but as soon as I do the Save button becomes greyed out. Even after filling out all fields for the connection it is still grey and I am unable to save the static IP connection information. Any thoughts would be greatly appreciated. I'm hoping there is just some new setting that I am unaware of.... On another note, if I stop the network manager and go edit the interfaces file (and the appropriate hosts/routes/dns files), I do get a static ip address assigned and I can contact my server from the outside, however, the server cannot find the internet. Can't ping even its own ip... I can ping the loopback interface though. I'm really confused on this one. Hoping someone can offer some help.

  • What You Said: How You Set Up a Novice-Proof Computer

    - by Jason Fitzpatrick
    Earlier this week we asked you to share your tips and tricks for setting up a novice-proof computer; read on to see how your fellow readers ensure friends and relatives have a well protected computer. Image available as wallpaper here. If you only listen to a single bit of advice from your fellow readers, let that advice be the importance of separate and non-administrative user accounts. Grant writes: I have two boys, now 8 and 10, who have been using the computer since age 2. I set them up on Linux (Debian first, now Ubuntu) with a limited rights account. They can only make a mess of their own area. Worst case, empty their home directory and let them start over. I have to install software for them, but they can’t break the machine without causing physical damage (hammers, water, etc.) My wife was on Windows, and I was on Debian, and before they had their own, they knew they could only use my computer, and only logged in as themselves. All accounts were password protected, so that was easy to enforce. What Is the Purpose of the “Do Not Cover This Hole” Hole on Hard Drives?

  • Following a set of points?

    - by user1010005
    Lets assume that i have a set of path that an entity should follow : const int Paths = 2 Vector2D<float> Path[Paths] = { Vector2D(100,0),Vector2D(100,50) }; Now i define my entity's position in a 2D vector as follows : Vector2D<float> FollowerPosition(0,0); And now i would like to move the "follower" to the path at index 1 : int PathPosition = 0; //Start with path 1 Currently i do this : Vector2D<float>& Target = Path[PathPosition]; bool Changed = false; if (FollowerPosition.X < Target.X) FollowerPosition.X += Vel,Changed = true; if (FollowerPosition.X > Target.X) FollowerPosition.X -= Vel,Changed = true; if (FollowerPosition.Y < Target.Y) FollowerPosition.Y += Vel;,Changed = true; if (FollowerPosition.Y > Target.Y) FollowerPosition.Y -= Vel,Changed = true; if (!Changed) { PathPosition = PathPosition + 1; if (PathPosition > Paths) PathPosition = 0; } Which works except for one little detail : The movement is not smooth!! ...So i would like to ask if anyone sees anything wrong with my code. Thanks and sorry for my english.

  • "drm:[drm_crtc_helper_set_config] *ERROR* failed to set mode on [CRTC6]" during install

    - by Warez J. Coxtrong
    I have a desktop PC which I built a while back. It has an Athlon XP 2500+, 2.5GB RAM, and an Nvidia (PNY Verto) Geforce 6200. I removed the CD drive to add another hard drive so I install from a USB flash drive. When I try to install 12.04 it seems to work just fine. The GUI boots up and wifi even connects to my router. I go through the language screen, the partition screen, the keyboard screen, the location screen, and the import my Windows settings screen just fine. But as soon as I'm done with all that the next screen goes black and displays this message: drm:[drm_crtc_helper_set_config] *ERROR* failed to set mode on [CRTC6] Since the GUI starts just fine earlier during the install, I know I shouldn't be having any display problems, but I am. How do I get Ubuntu to install properly? I have four IDE hard drives, all Western Digital: a 250GB, a 160GB, a 40GB occupied by Windows XP, and a 120GB that I'm trying to use for Ubuntu. 3GB of the 120GB drive are formatted for swap. I have checked the MD5sum of install image file and it all matches up. d791352694374f1c478779f7f4447a3f ubuntu-12.04-desktop-i386.iso

  • Retrieve parent node from selection (range) in Gecko and Webkit

    - by Jason
    I am trying to add an attribute when using a wysiwyg editor that uses "createLink" command. I thought it would be trivial to get back the node that is created after the browse executes that command. Turns out, I am only able to grab this newly created node in IE. Any ideas? The following code demonstrates the issue (debug logs at bottom show different output in each browser): var getSelectedHTML = function() { if ($.browser.msie) { return this.getRange().htmlText; } else { var elem = this.getRange().cloneContents(); return $("<p/>").append($(elem)).html(); } }; var getSelection = function() { if ($.browser.msie) { return this.editor.selection; } else { return this.iframe[0].contentDocument.defaultView.getSelection(); } }; var getRange = function() { var s = this.getSelection(); return (s.getRangeAt) ? s.getRangeAt(0) : s.createRange(); }; var getSelectedNode = function() { var range = this.getRange(); var parent = range.commonAncestorContainer ? range.commonAncestorContainer : range.parentElement ? range.parentElement(): range.item(0); return parent; }; // **** INSIDE SOME EVENT HANDLER **** if ($.browser.msie) { this.ec("createLink", true); } else { this.ec("createLink", false, prompt("Link URL:", "http://")); } var linkNode = $(this.getSelectedNode()); linkNode.attr("rel", "external"); $.log(linkNode.get(0).tagName); // Gecko: "body" // IE: "a" // Webkit: "undefined" $.log(this.getSelectedHTML()); // Gecko: "<a href="http://site.com">foo</a>" // IE: "<A href="http://site.com" rel=external>foo</A>" // Webkit: "foo" $.log(this.getSelection()); // Gecko: "foo" // IE: [object Selection] // Webkit: "foo" Thanks for any help on this, I've scoured related questions on SO with no success!

  • Find position of a node within a nodeset using xpath

    - by Phil Nash
    After playing around with position() in vain I was googling around for a solution and arrived at this older stackoverflow question which almost describes my problem. The difference is that the nodeset I want the position within is dynamic, rather than a contiguous section of the document. To illustrate I'll modify the example from the linked question to match my requirements. Note that each <b> element is within a different <a> element. This is the critical bit. <root <a <bzyx</b </a <a <bwvu</b </a <a <btsr</b </a <a <bqpo</b </a </root Now if I queried, using XPath for a/b I'd get a nodeset of the four <b> nodes. I want to then find the position within that nodeset of the node that contains the string 'tsr'. The solution in the other post breaks down here: count(a/b[.='tsr']/preceding-sibling::*)+1 returns 1 because preceding-sibling is navigating the document rather than the context node-set. Is it possible to work within the context nodeset?

  • populate textboxs with xml node attributes

    - by Doug
    I have Data.xml: <?xml version="1.0" encoding="utf-8" ?> <data> <album> <slide title="Autum Leaves" description="Leaves from the fall of 1986" source="images/Autumn Leaves.jpg" thumbnail="images/Autumn Leaves_thumb.jpg" /> <slide title="Creek" description="Creek in Alaska" source="images/Creek.jpg" thumbnail="images/Creek_thumb.jpg" /> </album> </data> I'd like to be able to edit the attributes of each Slide node via GridView (that has a "Select" column added.) And so far I have: protected void GridView1_SelectedIndexChanged(object sender, EventArgs e) { int selectedIndex = GridView1.SelectedIndex; LoadXmlData(selectedIndex); } private void LoadXmlData(int selectedIndex) { XmlDocument xmldoc = new XmlDocument(); xmldoc.Load(MapPath(@"..\photo_gallery\Data.xml")); XmlNodeList nodelist = xmldoc.DocumentElement.ChildNodes; XmlNode xmlnode = nodelist.Item(selectedIndex); titleTextBox.Text = xmlnode.Attributes["title"].InnerText; descriptionTextBox.Text = xmlnode.Attributes["description"].InnerText; sourceTextBox.Text = xmlnode.Attributes["source"].InnerText; thumbTextBox.Text = xmlnode.Attributes["thumbnail"].InnerText; The code for LoadXmlData is just a guess on my part - I'm new to working with xml in this way. I'd like have the user to slected the row from the gridview, then populate a set of text boxes with each slide attributed for updating back to the Data.xml file. The error I'm getting is "Object reference not set to an instance of an object" at the line: titleTextBox.Text = xmlnode.Attributes["@title"].InnerText; - so I'm not reaching the attribute "title" of the slide node. Thanks for any ideas you may have.

  • Set App Windows to Always be on Top

    - by Asian Angel
    Sometimes you have a small app or other software that you want to keep topmost but how do you keep it on top without a lot of hassle? If this sounds like your situation then you might want to have a look at OnTop. Before For our example we had four individual apps open…any of the four could easily be on top at the moment. OnTop in Action The exe file for the app comes in a zip file. Simply unzip the file, place it in the Program Files Folder, create a shortcut and you are ready to go. Once you start OnTop you will see a new System Tray Icon…right click to access the Context Menu with a list of currently open apps. We decided to set Winamp to be always topmost first. Note: OnTop detected all three individual sections of our Winamp Player along with the individual monitors running in our Taskbar. Clicking on Paint.NET brought it forward over Firefox and Microsoft Word but Winamp was still sitting on top. Clicking on Microsoft Word next still did not affect Winamp’s topmost status. Nice. As soon as we switched the topmost status to Microsoft Word you can see that it immediately came to the front. One thing that we did note in our tests…the best method for switching topmost status is either to choose a different app or close the app that was topmost. Conclusion OnTop might be considered niche software but if you have an app window that you need to keep on top of other windows then you might want to give this small app a try.

  • Ubuntu Preseed set Norwegian Keyboard?

    - by Vangelis Tasoulas
    It's been a couple of days now that I am trying to make a fully automated unattended installation. I managed to make it work with Ubuntu/Cobbler and a preseed file, but I cannot set the correct keyboard layout which is Norwegian in this case. I am doing the tests on a virtual machine and when I am going with a normal manual installation (no preseed) everything is working fine. When I am using the preseed file, I always end up with an "English (US)" keyboard no matter the many different options I have tried. I can change it manually with the "dpkg-reconfigure keyboard-configuration" command, but that's not the case. It should be handled automatically using the preseed file. I am using DEBCONF_DEBUG=5 when the grub is loading, and as I see in "/var/log/installer/syslog" file after the installation has finished, the preseeding commands are accepted. Can anyone help on this? The preseed file I am using is following: d-i debian-installer/country string NO d-i debian-installer/language string en_US:en d-i debian-installer/locale string en_US.UTF-8 d-i console-setup/ask_detect boolean false d-i keyboard-configuration/layout select Norwegian d-i keyboard-configuration/variant select Norwegian d-i keyboard-configuration/modelcode string pc105 d-i keyboard-configuration/layoutcode string no d-i keyboard-configuration/xkb-keymap select no d-i netcfg/choose_interface select auto d-i netcfg/get_hostname string myhostname d-i netcfg/get_domain string simula.no d-i hw-detect/load_firmware boolean true d-i mirror/country string manual d-i mirror/http/hostname string ftp.uninett.no d-i mirror/http/directory string /ubuntu d-i mirror/http/proxy string http://10.0.1.253:3142/ d-i mirror/codename string precise d-i mirror/suite string precise d-i clock-setup/utc boolean true d-i time/zone string Europe/Oslo d-i clock-setup/ntp boolean true d-i clock-setup/ntp-server string 10.0.1.254 d-i partman-auto/method string lvm partman-auto-lvm partman-auto-lvm/new_vg_name string vg0 d-i partman-auto/purge_lvm_from_device boolean true d-i partman-lvm/device_remove_lvm boolean true d-i partman-md/device_remove_md boolean true d-i partman-lvm/confirm boolean true d-i partman-lvm/confirm_nooverwrite boolean true d-i partman-auto-lvm/guided_size string max d-i partman-auto/choose_recipe select 30atomic d-i partman/default_filesystem string ext4 d-i partman-partitioning/confirm_write_new_label boolean true d-i partman/choose_partition select finish d-i partman/confirm boolean true d-i partman/confirm_nooverwrite boolean true d-i partman/mount_style select uuid d-i passwd/root-login boolean false d-i passwd/make-user boolean true d-i passwd/user-fullname string vangelis d-i passwd/username string vangelis d-i passwd/user-password-crypted password $6$asdafdsdfasdfasdf d-i passwd/user-uid string d-i user-setup/allow-password-weak boolean false d-i passwd/user-default-groups string adm cdrom dialout lpadmin plugdev sambashare d-i user-setup/encrypt-home boolean false d-i apt-setup/restricted boolean true d-i apt-setup/universe boolean true d-i apt-setup/backports boolean true d-i apt-setup/services-select multiselect security d-i apt-setup/security_host string security.ubuntu.com d-i apt-setup/security_path string /ubuntu tasksel tasksel/first multiselect Basic Ubuntu server, OpenSSH server d-i pkgsel/include string build-essential htop vim nmap ntp d-i pkgsel/upgrade select safe-upgrade d-i pkgsel/update-policy select none d-i pkgsel/updatedb boolean true d-i grub-installer/only_debian boolean true d-i grub-installer/with_other_os boolean true d-i finish-install/keep-consoles boolean false d-i finish-install/reboot_in_progress note d-i cdrom-detect/eject boolean true d-i debian-installer/exit/halt boolean false d-i debian-installer/exit/poweroff boolean false

  • How to set up secure cookie on weblogic server

    - by adejuanc
    WebLogic Server allows a user to securely access HTTPS resources in a session that was initiated using HTTP, without loss of session data. To enable this feature, add AuthCookieEnabled="true" to the WebServer element in config.xml: <WebServer Name="myserver" AuthCookieEnabled="true"/>Setting AuthCookieEnabled to true, which is the default setting, causes the WebLogic Server instance to send a new secure cookie, _WL_AUTHCOOKIE_JSESSIONID, to the browser when authenticating via an HTTPS connection. Once the secure cookie is set, the session is allowed to access other security-constrained HTTPS resources only if the cookie is sent from the browser.Thus, WebLogic Server uses two cookies: the JSESSIONID cookie and the _WL_AUTHCOOKIE_JSESSIONID cookie. By default, the JSESSIONID cookie is never secure, but the _WL_AUTHCOOKIE_JSESSIONID cookie is always secure. A secure cookie is only sent when an encrypted communication channel is in use. Assuming a standard HTTPS login (HTTPS is an encrypted HTTP connection), your browser gets both cookies.For subsequent HTTP access, you are considered authenticated if you have a valid JSESSIONID cookie, but for HTTPS access, you must have both cookies to be considered authenticated. If you only have the JSESSIONID cookie, you must re-authenticate.To configure on Admin Console : Log into WebLogic Admin Console. Under Domain Structure, press click on <domainname> Select the "Web Applications" tab Select "Lock and Edit" in change center. Click on  "Auth Cookie Enabled" checkbox. Restart to confirm changes. Test an application and view the cookie which got stored as "JSESSIONID" To Configure the Web application's weblogic-application.xml file: Run the following to extract the file from the web application's weblogic-application.xml: $PATH_JDK_HOME\binjar -xvf easy-web-examples.ear META-INF/weblogic-application.xml Add <cookie-secure>true</cookie-secure> between <session-descriptor> </session-descriptor> to the weblogic-application.xml. Run the following to repackage the file to the application: $PATH_JDK_HOME\bin\jar -uvf easy-web-examples.ear META-INF/weblogic-application.xml Deploy the application into WebLogic For further information, please read the documentation on "Using Secure Cookies to Prevent Session Stealing " : http://download.oracle.com/docs/cd/E12840_01/wls/docs103/security/thin_client.html#wp1053780

  • how do I set quad buffering with jogl 2.0

    - by tony danza
    I'm trying to create a 3d renderer for stereo vision with quad buffering with Processing/Java. The hardware I'm using is ready for this so that's not the problem. I had a stereo.jar library in jogl 1.0 working for Processing 1.5, but now I have to use Processing 2.0 and jogl 2.0 therefore I have to adapt the library. Some things are changed in the source code of Jogl and Processing and I'm having a hard time trying to figure out how to tell Processing I want to use quad buffering. Here's the previous code: public class Theatre extends PGraphicsOpenGL{ protected void allocate() { if (context == null) { // If OpenGL 2X or 4X smoothing is enabled, setup caps object for them GLCapabilities capabilities = new GLCapabilities(); // Starting in release 0158, OpenGL smoothing is always enabled if (!hints[DISABLE_OPENGL_2X_SMOOTH]) { capabilities.setSampleBuffers(true); capabilities.setNumSamples(2); } else if (hints[ENABLE_OPENGL_4X_SMOOTH]) { capabilities.setSampleBuffers(true); capabilities.setNumSamples(4); } capabilities.setStereo(true); // get a rendering surface and a context for this canvas GLDrawableFactory factory = GLDrawableFactory.getFactory(); drawable = factory.getGLDrawable(parent, capabilities, null); context = drawable.createContext(null); // need to get proper opengl context since will be needed below gl = context.getGL(); // Flag defaults to be reset on the next trip into beginDraw(). settingsInited = false; } else { // The following three lines are a fix for Bug #1176 // http://dev.processing.org/bugs/show_bug.cgi?id=1176 context.destroy(); context = drawable.createContext(null); gl = context.getGL(); reapplySettings(); } } } This was the renderer of the old library. In order to use it, I needed to do size(100, 100, "stereo.Theatre"). Now I'm trying to do the stereo directly in my Processing sketch. Here's what I'm trying: PGraphicsOpenGL pg = ((PGraphicsOpenGL)g); pgl = pg.beginPGL(); gl = pgl.gl; glu = pg.pgl.glu; gl2 = pgl.gl.getGL2(); GLProfile profile = GLProfile.get(GLProfile.GL2); GLCapabilities capabilities = new GLCapabilities(profile); capabilities.setSampleBuffers(true); capabilities.setNumSamples(4); capabilities.setStereo(true); GLDrawableFactory factory = GLDrawableFactory.getFactory(profile); If I go on, I should do something like this: drawable = factory.getGLDrawable(parent, capabilities, null); but drawable isn't a field anymore and I can't find a way to do it. How do I set quad buffering? If I try this: gl2.glDrawBuffer(GL.GL_BACK_RIGHT); it obviously doesn't work :/ Thanks.

  • Fastest way to perform subset test operation on a large collection of sets with same domain

    - by niktech
    Assume we have trillions of sets stored somewhere. The domain for each of these sets is the same. It is also finite and discrete. So each set may be stored as a bit field (eg: 0000100111...) of a relatively short length (eg: 1024). That is, bit X in the bitfield indicates whether item X (of 1024 possible items) is included in the given set or not. Now, I want to devise a storage structure and an algorithm to efficiently answer the query: what sets in the data store have set Y as a subset. Set Y itself is not present in the data store and is specified at run time. Now the simplest way to solve this would be to AND the bitfield for set Y with bit fields of every set in the data store one by one, picking the ones whose AND result matches Y's bitfield. How can I speed this up? Is there a tree structure (index) or some smart algorithm that would allow me to perform this query without having to AND every stored set's bitfield? Are there databases that already support such operations on large collections of sets?

  • Why Won't the WebSocket.onmessage Event Fire?

    - by SumWon
    Hey guys, After toying around with this for hours, I simply cannot find a solution. I'm working on a WebSocket server using "node.js" for a canvas based online game I'm developing. My game can connect to the server just fine, it accepts the handshake and can even send messages to the server. However, when the server responds to the client, the client doesn't get the message. No errors, nothing, it just sits there peacefully. I've ripped apart my code, trying everything I could think of to fix this, but alas, nothing. Here's a stripped copy of my server code. As I said before, the handshake works fine, the server receives data fine, but sending data back to the client does not. var sys = require('sys'), net = require('net'); var server = net.createServer(function (stream) { stream.setEncoding('utf8'); var shaken = 0; stream.addListener('connect', function () { sys.puts("New connection from: "+stream.remoteAddress); }); stream.addListener('data', function (data) { if (!shaken) { sys.puts("Handshaking..."); //Send handshake: stream.write( "HTTP/1.1 101 Web Socket Protocol Handshake\r\n"+ "Upgrade: WebSocket\r\n"+ "Connection: Upgrade\r\n"+ "WebSocket-Origin: http://192.168.1.113\r\n"+ "WebSocket-Location: ws://192.168.1.71:7070/\r\n\r\n"); shaken=1; sys.puts("Handshaking complete."); } else { //Message received, respond with 'testMessage' var d = "testMessage"; var m = '\u0000' + d + '\uffff'; sys.puts("Sending '"+m+"' to client"); var result = stream.write(m, "utf8"); sys.puts(result); /* Result comes as true, meaning that it pushed the data out. Why isn't the client seeing it?!? */ } }); stream.addListener('end', function () { sys.puts("Connection closed!"); stream.end(); }); }); server.listen(7070); sys.puts("Server Started!");

I guess, it would look somewhat like this in agularjs First we receive a password in login controller. $scope.signup = function() { var user = { password: $scope.password, }; $http.post('/auth/signup', user); }; Send it via http.post and get in in our node server file. We are provided with a compare password bcrypt function userSchema.methods.comparePassword = function(candidatePassword, cb) { bcrypt.compare(candidatePassword, this.password, function(err, isMatch) { if (err) return cb(err); cb(null, isMatch); }); }; So right now we are creating function to catch our http request app.post('/auth/signup', function(req, res, next) { Inside we use a compair password function to realize if such password exists or not yet. So we have to encrypt a password with bcrypt to make a comparison First we hash it same way as in .pre var encPass; bcrypt.genSalt(10, function(err, salt) { if (err) return next(err); bcrypt.hash(req.body.password, salt, function(err, hash) { if (err) return next(err); encPass=hash; )}; )}; We have encrypted password stored in encPass so now we follow to finding a user in database with this password User.findOne({ password: encPass }, function(err, user) { if (user) { //user exists, it means we should pass an ID of this user to a controller to display it in a view. I don't know how. res.send({user.name}) //like this? How should controller receive this? With $http.post? } else { and now if user doesn't exist - we should create it with user ID generated by my function var nUser = new User({ name: generId(), password: req.body.password }); nUser.save(function(err) { if (err) return next(err); )}; )}; )}; Am I doing anything right? I'm pretty new to js and angular. If so - how do I throw a username back at controller? If someone is interested - this service exists for 100+ symbol passphrases so possibility of entering same passphrase as someone else is miserable. And yeah, If someone logged in under 123 password - the other guy will log in as same user if he entered 123 password, but hey, you are warned to make a big passphrase. So I'm confident about the idea and I only need a help with understanding and realization.

  • Virtual server hardware to simulate 3-4 node web farm

    - by frankadelic
    I would like to get a dedicated server to run VMWare, VirtualBox, or similar. On this box, I would like to host 3-4 virtual instances of Linux, to act as nodes in a web farm. Performance is not that important, this would only be for testing and experimenting. I need something sub $1000 (including tax/shipping). Can someone recommend a pre-built server that would do the trick? I am pretty ignorant of hardware so building one is not going to work for me. Also, would I need multiple network cards to simulate a web farm or can the virtualization software handle that for me. Thanks
