  • Simple jquery Fade Slideshow fails on certain browsers

    - by cmay
    So I have a simple slideshow on my website which just shows one image then shows another until it reaches the end or the user hits skip in which case it shows index.html. The site is served on apache2 with Django. The slideshow works perfectly on most machines, but certain machines it shows some images twice and other images not at all and the timing is off. I am using jquery 1.4.3. Below is the section of html where I push the image urls from the database to the javascript {% for image in latest_images %} {% thumbnail image.image_file "800x600" crop="center" as im %} <script>FadeImageList.push("{{im.url}}");</script> {% endthumbnail %} {% endfor %} Below is the full javascript file var FadeImageList = []; var fadeDuration = 2000; var fadeImgID = '#slideShow'; var homePageID = '#homePage'; var menuID = '#menu'; var skipFlag = 0; $(document).ready(function(){ $(homePageID).fadeOut(50); PlaySlideshow(FadeImageList); }); var PlaySlideshow = function(FadeImageList){ var newImgSrc = FadeImageList.shift(); $('#skip').click(function(){$('#loader').show();skipFlag = 1;}); if(((typeof(newImgSrc) !== "string") || (skipFlag === 1))){ EndSlideShow(); return; } else{ $(fadeImgID).fadeOut(fadeDuration,function(){ $(fadeImgID).attr('src', newImgSrc); $(fadeImgID).fadeIn(fadeDuration,function(){ PlaySlideshow(FadeImageList); }); }); } }; var EndSlideShow = function(fadeSettings){ $(fadeImgID).fadeOut(400,function(){ $(homePageID).fadeIn(400); $("#skip").fadeOut(400); $('#loader').hide(); }); }; The strange thing is I've had it work and fail on identically version numbered browsers on the same os but on different machines. It consistently either works or fails on a machine. I've had it fail in ie 7,8 firefox 3.6.3 and chrome. I've also had it succeed in ie6,7,8 firefox 3.6.3,3.4.2,3.1 and chrome.

  • Would the instance reference parameters passed into the static methods get garbage collected?

    - by 123Developer
    I know that the static objects in .Net managed world are loaded in Loader Heap which is never going to be garbage collected. What happens to the instance reference parameters passed to a static methods. Are they get garbage collected once the static function executed completely Or they are going to live forever as those instance reference variables are once passed to static method? I am really confused this evening; Please guide me. Thanks and regards 123Developer.

    I have this code $("body").on({ click: function(event){ event.preventDefault(); var aLink = $(this).attr("href"); $("#content").load(aLink+" #loader", function(){ //Callback here }); $("#crumbbar").load(aLink+' .breadcrumbs', function(){ //Callback here }); } }, "a"); Can this be optimized in such a way that I only have 1 load command?

  • Why doesn't the Ubuntu Installer see all of my hard drives

    - by atodd
    I'm trying to setup a dual boot system with Windows Vista 64 (already installed) and Ubuntu 10.10. I added a new drive which is identical to the one Vista is installed on. When I boot into the LiveCD I can see and mount the second drive and edit it in Gparted. However, when I use the installer it will only bring up the drive that already has Vista installed. I've tried everything I know. I'm not sure if its a BIOS setting or something else I've missed.

  • jQuery.post not working when using data type json

    - by swift
    I have been trying to utilize json in this jQuery.post because I need to return two values from my executed php. The code was working when I was not implementing json. I need to see if a promo code entered is valid for a particular broker. The two variables I need back are the instant message whether or not it's valid (this is displayed to the user) and I need to update a hidden field that will be used later while updating the database. The jQuery.post does not seem to be firing at all, but the code directly above it (the ajax-loader.gif) is working. I did re-write the whole thing at one point using jQuery.ajax, and had issues there too. Granted, I have probably been looking at this too long and have tried to re-write too many times, but any help is greatly appreciated!! Here's the jQuery.post <!-- Below Script is for Checking Promo Code Against Database--> <script type="text/javascript"> jQuery(document).ready(function() { jQuery("#promocode").keyup(function (e) { //removes spaces from PromoCode jQuery(this).val(jQuery(this).val().replace(/\s/g, '')); var promocode = jQuery(this).val(); var brokerdealerid = document.getElementById("BrokerDealerId").value; if(promocode.length > 0 ){ jQuery("#promo-result").html('<img src="../imgs/ajax-loader.gif" />'); jQuery.post( '../check_promocode.php', {promocode:promocode, brokerdealerid:brokerdealerid}, function(data) { $("#promo-result").html(data.promoresult); $("#promo-result-valid").html(data.promovalid); }, "json"); } }); }); </script> <!-- End Script is for Checking Promo Code Against Database--> Here's relevant code from check_promocode.php: //sanitize incoming parameters if (isset($_POST['brokerdealerid'])) $brokerdealerid = sanitizeMySQL($_POST['brokerdealerid']); $promocode = sanitizeMySQL($promocode); //check promocode in db $results = mysql_query("SELECT PromotionCodeIdentifier FROM PromotionCode WHERE PromotionCodeIdentifier='$promocode' AND BrokerDealerId='$brokerdealerid' AND PromotionCodStrtDte <= CURDATE() AND PromotionCodExpDte >= CURDATE()"); //return total count $PromoCode_exist = mysql_num_rows($results); //total records //if value is more than 0, promocode is valid if($PromoCode_exist) { echo json_encode(array("promoresult"=>"Promotion Code Valid", "promovalid"=>"Y")); exit(); }else{ echo json_encode(array("promoresult"=>"Invalid Promotion Code", "promovalid"=>"N")); exit(); }

  • overriding new ubuntu installation

    - by tkoomzaaskz
    I've got a ubuntu 11.10 which has lost its support in May 2013, now I'd like to reintall up to the most up-to-date LTS, which is 12.04. My question is regarding my current partitions and doing backups. Is there a safe way to backup my data on some local partitions instead of copying files into DVDs/external drives (this is very uncormortable in my situation). Following are system commands shoing my disk: $ lsblk NAME MAJ:MIN RM SIZE RO MOUNTPOINT sda 8:0 0 232,9G 0 +-sda1 8:1 0 48,8G 0 +-sda2 8:2 0 63G 0 +-sda3 8:3 0 1K 0 +-sda4 8:4 0 53,7G 0 / +-sda5 8:5 0 18,6G 0 +-sda6 8:6 0 25,5G 0 +-sda7 8:7 0 23,3G 0 [SWAP] sr0 11:0 1 1024M 0 and $ sudo fdisk -l [sudo] password for xyz: Disk /dev/sda: 250.1 GB, 250059350016 bytes glowic: 255, sektorów/sciezke: 63, cylindrów: 30401, w sumie sektorów: 488397168 Jednostka = sektorów, czyli 1 * 512 = 512 bajtów Rozmiar sektora (logiczny/fizyczny) w bajtach: 512 / 512 Rozmiar we/wy (minimalny/optymalny) w bajtach: 512 / 512 Identyfikator dysku: 0xc3ffc3ff Device Boot Beginning End Blocks ID System /dev/sda1 * 2048 102402047 51200000 7 HPFS/NTFS/exFAT /dev/sda2 215044096 347080703 66018304 7 HPFS/NTFS/exFAT /dev/sda3 347082750 488392064 70654657+ 5 Extended /dev/sda4 102402048 215042047 56320000 83 Linux /dev/sda5 395905923 434975939 19535008+ 83 Linux /dev/sda6 434976003 488392064 26708031 83 Linux /dev/sda7 347082752 395905023 24411136 82 Linux swap / Solaris In the beginning I had Windows Vista pre-installed with the machine when it was bought (damn!) and I installed linux (the one I have now). The windows-program in master boot record has been overriden by grub and now I can boot with both Windows and Linux. This is list of mounted devices: $ mount /dev/sda4 on / type ext4 (rw,errors=remount-ro,commit=0) proc on /proc type proc (rw,noexec,nosuid,nodev) sysfs on /sys type sysfs (rw,noexec,nosuid,nodev) fusectl on /sys/fs/fuse/connections type fusectl (rw) none on /sys/kernel/debug type debugfs (rw) none on /sys/kernel/security type securityfs (rw) udev on /dev type devtmpfs (rw,mode=0755) devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620) tmpfs on /run type tmpfs (rw,noexec,nosuid,size=10%,mode=0755) none on /run/lock type tmpfs (rw,noexec,nosuid,nodev,size=5242880) none on /run/shm type tmpfs (rw,nosuid,nodev) binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,noexec,nosuid,nodev) gvfs-fuse-daemon on /home/tomasz/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=tomasz) It's strange (I don't remember such thing) that my current linux uses only one partition (/dev/sda4). But, anyway, it seems like that. My final question is: am I able to use one of the existing linux partitions for a backup and install ubuntu 12.04 without removing neither windows nor ubuntu 11.04? I mean - will grub automatically accept both old windows vista and 2 linuxes (old 11.10 and "new" 12.04)? Is there any hidden operation done while installation that could harm my custom-backup-partition while installing? my fstab file: proc /proc proc nodev,noexec,nosuid 0 0 # / was on /dev/sda4 during installation UUID=d44e89f5-9da2-48eb-83b3-887652ec95d2 / ext4 errors=remount-ro 0 1 # swap was on /dev/sda7 during installation UUID=bbe50535-ba57-434a-9272-211d859f0e00 none swap sw 0 0 sda5 and sda6 are trash partitions created during unsuccessful linux installation (this was linux installation before my current installation), I didn't delete these partitions, but I have access to them (and I can use them as backup partitions). edit: second question is: why does lsblk show /dev/sda having 232,9G while fdisk shows that it has 250.1GB? Where does the difference come from?

  • Windows 7 sometimes boots in VGA mode

    - by TuxRug
    I have an Asus G50VT-x5 laptop with nVidia GeForce9800M-GS graphics. Normally, Windows boots normally, but about 20% of the time (rough estimate), it will boot with the fallback VGA driver, maxing out at 800x600 with no Aero. I've checked the system logs and there is nothing indicating an error loading the nVidia driver. It even specifies in the logs that the Nvidia Display Driver service started successfully, even though it has booted in safe graphics mode. This has been happening for a while, but it's happening a little more often now than it was before. Since the first time my system exhibited this behavior, I have updated my graphics driver a handful of times. I used System Information for Windows to check for problems there, but the only thing that stood out was the following: Core Temperature 4486449 °C (8075639 °F) Shaders Temperature 1171513530 °C (2108724330 °F) I know this reading is incorrect, because my laptop is nowhere near the surface of the sun and my desk has not burst into flames. When it's opererating normally, I get a sane reading like [Core Temperature 58 °C (136 °F)] with no Shaders Temperature listed. All I have to do to resolve the issue is reboot. I have seen no stability issues with the graphics or anything else. A long time ago, I had an issue with this computer where my framerate would suddenly drop during a 3D game from 40fps to <1fps, but after looking at the temperature readout immediately after quitting a game, I removed the bottom panel and blew the dust out of the vent and heatsink. Since then I have no drops in framerate under any situation. I have uploaded a zip containing the SIW reports for when the problem is occurring and when the computer is operating normally. I don't have a paid account so it can only be downloaded 10 times, so please only download the reports if you think you can use them. If you try to download the reports and they are no longer available, please comment and I will re-upload them. If you want to look at the files, they are on Rapidshare. EDIT It happened again, and I looked a little deeper into the System logs. When this happens, there are a lot of errors about other device drivers unable to start. All of these errors are for PnP drivers. Also, my USB keyboard and mouse take a few moments before they actually start working, although this happens sometimes the first normal boot as well. I am quite sure this is related, so I am adding the pnp tag. Also, CHKDSK will not run on boot. Even if a check is scheduled or a volume is manually set as dirty, CHKDSK will be skipped entirely, not even leaving an entry in the System logs. I tried running CHKNTFS /D, which did not work. I then manually changed my HKLM\System\CurrentControlSet\Control\Session Manager BootExecute value to the default listed on Microsoft's website. That did not work either. I ended up booting to repair mode and running CHKDSK there, which found a number of minor inconsistencies on my system drive, but none on my data drive. I have no idea if this is related. Some more information for those who don't download my SIW report file: Antivirus and Firewall are ESET Smart Security I have three different virutalization programs installed: VMware Player, Windows Virtual PC, and VirtualBox. The network adapters for these show up in the log of failed device starts. EDIT 2 I tried running sfc /scannow, which reported that it found corrupted files that could not be fixed. The CBS log is extremely cryptic. I tried booting to my install disk, launching repair mode, and doing an offline sfc from there, which produced the same result.

  • How to use more than 3 virtual disks in Linux using CentOS and XenServer

    - by 010110110101
    I've attached 5 virtual disks to a Virtual Machine in Citrix XenServer. The VM has the xs-tools installed. Initially it said that it couldn't add so many disks. After I installed the xs-tools, it let me add all the disks. But /dev doesn't show all the disks. It shows these: /dev/xvda /dev/xvdb /dev/xvdc /dev/cdrom Perhaps it is bound by the limits of an IDE bus? (3 disks + CD-ROM) If so, how does one change the VM to use SCSI? Edit: According to the documentation: 2.6.3. VM Block Devices In the PV Linux case, block devices are passed through as PV devices. XenServer does not attempt to emulate SCSI or IDE, but instead provides a more suitable interface in the virtual environment in the form of xvd* devices. It is also possible to get an sd* device using the same mechanism, where the PV driver inside the VM takes over the SCSI device namespace. This is not desirable so it is best to use xvd* where possible for PV guests (this is the default for Debian and RHEL). For Windows or other fully virtualized guests, XenServer emulates an IDE bus in the form of an hd* device. When using Windows, installing the Citrix Tools for Virtual Machines installs a special PV driver that works in a similar way to Linux, except in the fully virtualized environment. Still, with 5 virtual disks attached, I don't see the other xvd devices. Edit #2: (attached requested info) Host Machine: XenServer 6.1 Linux version 2.6.32.43-0.4.1.xs1.6.10.777.170770xen (geeko@buildhost) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-51)) #1 SMP Wed Apr 17 05:52:03 EDT 2013 Guest Machine: CentOS release 6.4 (Final) Linux version 2.6.32-358.6.2.el6.x86_64 ([email protected]) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-3) (GCC) ) #1 SMP Thu May 16 20:59:36 UTC 2013 Output of 'fdisk -l' on Guest Machine: Note, the disk beyond the first 3 attached are not displaying -- there should be 4 100GB disks.

  • Can't remove GPT data from MBR

    - by user2373121
    I am having difficulty getting the Ubuntu installer (and gparted) to recognize the partitions on my MBR type disk. Other operating systems and disk tools read the disk structure and the files on it fine. I have used fixparts to write a new MBR but the issue persists.

  • Simplify your Ajax code by using jQuery Global Ajax Handlers and ajaxSetup low-level interface

    - by hajan
    Creating web applications with consistent layout and user interface is very important for your users. In several ASP.NET projects I’ve completed lately, I’ve been using a lot jQuery and jQuery Ajax to achieve rich user experience and seamless interaction between the client and the server. In almost all of them, I took advantage of the nice jQuery global ajax handlers and jQuery ajax functions. Let’s say you build web application which mainly interacts using Ajax post and get to accomplish various operations. As you may already know, you can easily perform Ajax operations using jQuery Ajax low-level method or jQuery $.get, $.post, etc. Simple get example: $.get("/Home/GetData", function (d) { alert(d); }); As you can see, this is the simplest possible way to make Ajax call. What it does in behind is constructing low-level Ajax call by specifying all necessary information for the request, filling with default information set for the required properties such as data type, content type, etc... If you want to have some more control over what is happening with your Ajax Request, you can easily take advantage of the global ajax handlers. In order to register global ajax handlers, jQuery API provides you set of global Ajax methods. You can find all the methods in the following link http://api.jquery.com/category/ajax/global-ajax-event-handlers/, and these are: ajaxComplete ajaxError ajaxSend ajaxStart ajaxStop ajaxSuccess And the low-level ajax interfaces http://api.jquery.com/category/ajax/low-level-interface/: ajax ajaxPrefilter ajaxSetup For global settings, I usually use ajaxSetup combining it with the ajax event handlers. $.ajaxSetup is very good to help you set default values that you will use in all of your future Ajax Requests, so that you won’t need to repeat the same properties all the time unless you want to override the default settings. Mainly, I am using global ajaxSetup function similarly to the following way: $.ajaxSetup({ cache: false, error: function (x, e) { if (x.status == 550) alert("550 Error Message"); else if (x.status == "403") alert("403. Not Authorized"); else if (x.status == "500") alert("500. Internal Server Error"); else alert("Error..."); }, success: function (x) { //do something global on success... } }); .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Now, you can make ajax call using low-level $.ajax interface and you don’t need to worry about specifying any of the properties we’ve set in the $.ajaxSetup function. So, you can create your own ways to handle various situations when your Ajax requests are occurring. Sometimes, some of your Ajax Requests may take much longer than expected… So, in order to make user friendly UI that will show some progress bar or animated image that something is happening in behind, you can combine ajaxStart and ajaxStop methods to do the same. First of all, add one <div id=”loading” style=”display:none;”> <img src="@Url.Content("~/Content/images/ajax-loader.gif")" alt="Ajax Loader" /></div> anywhere on your Master Layout / Master page (you can download nice ajax loading images from http://ajaxload.info/). Then, add the following two handlers: $(document).ajaxStart(function () { $("#loading").attr("style", "position:absolute; z-index: 1000; top: 0px; "+ "left:0px; text-align: center; display:none; background-color: #ddd; "+ "height: 100%; width: 100%; /* These three lines are for transparency "+ "in all browsers. */-ms-filter:\"progid:DXImageTransform.Microsoft.Alpha(Opacity=50)\";"+ " filter: alpha(opacity=50); opacity:.5;"); $("#loading img").attr("style", "position:relative; top:40%; z-index:5;"); $("#loading").show(); }); $(document).ajaxStop(function () { $("#loading").removeAttr("style"); $("#loading img").removeAttr("style"); $("#loading").hide(); }); .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Note: While you can reorganize the style in a more reusable way, since these are global Ajax Start/Stop, it is very possible that you won’t use the same style in other places. With this way, you will see that now for any ajax request in your web site or application, you will have the loading image appearing providing better user experience. What I’ve shown is several useful examples on how to simplify your Ajax code by using Global Ajax Handlers and the low-level AjaxSetup function. Of course, you can do a lot more with the other methods as well. Hope this was helpful. Regards, Hajan

  • Solaris 10 branded zone VM Templates for Solaris 11 on OTN

    - by jsavit
    Early this year I wrote the article Ours Goes To 11 which describes the ability to import Solaris 10 systems into a "Solaris 10 branded zone" under Oracle Solaris 11. I did this using Solaris 11 Express, and the capability remains in Solaris 11 with only slight changes. This important tool lets you painlessly inhaling a Solaris Container from Solaris 10 or entire Solaris 10 systems ("the global zone") into virtualized environments on a Solaris 11 OS. Just recently, Oracle provided Oracle VM Templates for Oracle Solaris 10 Zones to let you create Solaris 10 branded zones for Solaris 11 even if you don't currently have access to install media or a running Solaris 10 system. To use this, just download the Oracle VM Template for Oracle Solaris Zone 10 from OTN at http://www.oracle.com/technetwork/server-storage/solaris11/downloads/virtual-machines-1355605.html. This page contains images of Oracle Solaris 10 8/11 (the recent update to Solaris 10) in SPARC and x86 formats suitable for creating branded zones. The same page also has a VirtualBox image you can download for a complete Solaris 10 install in a guest virtual machine you can run on any host OS that supports VirtualBox. Both sets of downloads provide a quick - and extremely easy - way to set up a virtual Solaris 10 environment. In the case of the Oracle VM Templates, they illustrate several advanced features of Solaris 11. To start, just go to the above link, download the template for the hardware platform (SPARC or x86) you want, and download the README file also linked from that page. Install prerequisites The README file tells you to install the prerequisite Solaris 11 package that implements the Solaris 10 brand. Then you can install instances of zones with that brand. # pkg install pkg:/system/zones/brand/brand-solaris10 Packages to install: 1 Create boot environment: No Create backup boot environment: Yes DOWNLOAD PKGS FILES XFER (MB) Completed 1/1 44/44 0.4/0.4 PHASE ACTIONS Install Phase 74/74 PHASE ITEMS Package State Update Phase 1/1 Image State Update Phase 2/2 That took only a few minutes, and didn't require a reboot. Install the Solaris 10 zone Now it's time to run the downloaded template file. First make it executable via the chmod command, of course. I found that (unlike stated in the README) there was no need to rename the downloaded file to remove the .bin. When you run it you provide several parameters to describe the zone configuration: -a IP address - the IP address and optional netmask for the zone. This is the only mandatory parameter. -z zonename - the name of the zone you would like to create. -i interface - the package will create an exclusive-IP zone using a virtual NIC (vnic) based on this physical interface. In my case, I have a NIC called rge0. -p PATH - specifies the path in which you want the zoneroot to be placed. In my case, I have a ZFS dataset mounted at /zones, and this will create a zoneroot at /zones/s10u10. Kicking it off, you will see a copyright message, and then messages showing progress building the zone, which only takes a few minutes. # ./solaris-10u10-x86.bin -p /zones -a 192.168.1.100 -i rge0 -z s10u10 ... ... Checking disk-space for extraction Ok Extracting in /export/home/CDimages/s10zone/bootimage.ihaqvh ... 100% [===============================] Checking data integrity Ok Checking platform compatibility The host and the image do not have the same Solaris release: host Solaris release: 5.11 image Solaris release: 5.10 Will create a Solaris 10 branded zone.

Zone s10u10 booted The zone's root password has been set using the root password of the local host. You can change the zone's root password to further harden the security of the zone: being root, log into the zone from the local host with the command 'zlogin s10u10'. Once logged in, change the root password with the command 'passwd'. The nifty part in my opinion (besides being so easy), is that the zone was created as an exclusive-IP zone on a virtual NIC. This network configuration lets you enforce traffic isolation from other zones, enforce network Quality of Service, and even let the zone set its own characteristics like IP address and packet size. Independence of the zone's network characteristics from the global zone is one of the enhancements in Solaris 10 that make it easier to consolidate zones while preserving their autonomy, yet provide control in a consolidated environment. Let's see what the virtual network environment looks like by issuing commands from the Solaris 11 global zone. First I'll use Old School ifconfig, and then I'll use the new ipadm and dladm commands. # ifconfig -a4 lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1 inet 127.0.0.1 netmask ff000000 rge0: flags=1004943<UP,BROADCAST,RUNNING,PROMISC,MULTICAST,DHCP,IPv4> mtu 1500 index 2 inet 192.168.1.3 netmask ffffff00 broadcast 192.168.1.255 ether 0:14:d1:18:ac:bc vboxnet0: flags=201000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4,CoS> mtu 1500 index 3 inet 192.168.56.1 netmask ffffff00 broadcast 192.168.56.255 ether 8:0:27:f8:62:1c # dladm show-phys LINK MEDIA STATE SPEED DUPLEX DEVICE yge0 Ethernet unknown 0 unknown yge0 yge1 Ethernet unknown 0 unknown yge1 rge0 Ethernet up 1000 full rge0 vboxnet0 Ethernet up 1000 full vboxnet0 # dladm show-link LINK CLASS MTU STATE OVER yge0 phys 1500 unknown -- yge1 phys 1500 unknown -- rge0 phys 1500 up -- vboxnet0 phys 1500 up -- vnicZBI13379 vnic 1500 up rge0 s10u10/vnicZBI13379 vnic 1500 up rge0 s10u10/net0 vnic 1500 up rge0 # dladm show-vnic LINK OVER SPEED MACADDRESS MACADDRTYPE VID vnicZBI13379 rge0 1000 2:8:20:5c:1a:cc random 0 s10u10/vnicZBI13379 rge0 1000 2:8:20:5c:1a:cc random 0 s10u10/net0 rge0 1000 2:8:20:9d:d0:79 random 0 # ipadm show-addr ADDROBJ TYPE STATE ADDR lo0/v4 static ok 127.0.0.1/8 rge0/_a dhcp ok 192.168.1.3/24 vboxnet0/_a static ok 192.168.56.1/24 lo0/v6 static ok ::1/128 Log into the zone The install step already booted the zone, so lets log into it. Notice how you have to be appropriately privileged to log into a zone. This is my home system so I'm being a bit cavalier, but in a production environment you can give granular control of who can login to which zones. Voila! a Solaris 10 environment under a Solaris 11 kernel. Notice the output from the uname -a and ifconfig commands, and output from a ping to a nearby host. $ zlogin s10u10 zlogin: You lack sufficient privilege to run this command (all privs required) savit@home:~$ sudo zlogin s10u10 Password: [Connected to zone 's10u10' pts/5] Oracle Corporation SunOS 5.10 Generic Patch January 2005 # uname -a SunOS s10u10 5.10 Generic_Virtual i86pc i386 i86pc # ifconfig -a4 lo0: flags=2001000849 mtu 8232 index 1 inet 127.0.0.1 netmask ff000000 vnicZBI13379: flags=1000843 mtu 1500 index 2 inet 192.168.1.100 netmask ffffff00 broadcast 192.168.1.255 ether 2:8:20:5c:1a:cc # bash bash-3.2# ifconfig -a lo0: flags=2001000849 mtu 8232 index 1 inet 127.0.0.1 netmask ff000000 vnicZBI13379: flags=1000843 mtu 1500 index 2 inet 192.168.1.100 netmask ffffff00 broadcast 192.168.1.255 ether 2:8:20:5c:1a:cc bash-3.2# ping 192.168.1.2 192.168.1.2 is alive For fun, I configured Apache (setting its configuration file in /etc/apache2) and brought it up.

  • How to use Hybrid Graphic Switch on Sony Vaio Z?

    - by Travis R
    I got it to install nicely and it's all working, but I don't know which graphics card is being used nor how to switch between. I tried installing the official Nvidia drivers, but then I could not boot up my computer afterwards so I have not installed them again after doing a reinstall of Ubuntu. PS, if you have a grub install failure during install, the key is to tell it where to install the bootloader at the very beginning of the installation, on your partition selection screen (choose dev/mapper, not the /dev/sda it defaults to).

According to this Ubuntu-Wiki, support for Intel GMA-500 Poulsbo graphics is promising in Precise-Beta2 and should work out of the box. Of course the wiki talks about a problem when booting from USB and states that restarting X using: sudo service lightdm restart will bring a functional graphical desktop, but nothing happens for me!

  • Make Windows Position Your Dual Monitors Correctly

    - by Mysticgeek
    If you have a dual monitor setup and each monitor is a different size or height, it can be annoying trying to move the mouse pointer between them. Here is a quick tip that will help make the process easier. Align Monitors In our example, we’re using Windows 7, but the process is essentially the same in all versions, but getting to Display Settings is different. In Windows 7 open the Start menu and type display settings into the search box and hit Enter. In Vista right-click the desktop and click Personalize. Then from the Personalize appearance and sounds menu click on Display Settings. In XP right-click on the desktop and select Properties then in Display Properties click the Settings tab. Now here is where you can change the appearance of your monitors. In this example we have a larger 22” LCD and a smaller 19” and it can be annoying getting the mouse pointer from one to another depending where you are on each monitor. So what you want to do is simply move each display around to a particular height so it’s easier to get the pointer over. For example with this setting we know we’ll have no problem moving the pointer to the other screen at the top of each display.   Of course here you can flip your monitors around, change the display resolution, orientation, etc. If you have dual monitors where one might be larger or set up higher than the other, then this is a great way to get them finely tuned. You will have to play around with the settings a bit to settle on what works best for you.
