  • Les 8 gestes de Windows 8 à connaitre sur le bout des doigts, pour l'utiliser en version tactile. Par Gordon Fowler

    Les 8 gestes de Windows 8 A connaitre sur le bout des doigts pour l'utiliser en version tactile Windows 8. Ses nouveautés. Son Start Screen. Son optimisation pour le tactile? Et ses gestes pas du tout instinctifs dans une utilisation sur tablette si l'on essaye de s'y prendre comme sur Android ou iOS. Je dois vous avouer que je ne suis pas le plus brillant des testeurs. Je veux dire par là qu'il peut m'arriver ? sous les regards moqueurs de certains de mes confrères ? de mettre plusieurs minutes à configurer un compte BBM ou à me demander ou peut bien être ce satané bouton on/off. L'avantage d'être ainsi "limité", c'est que je peux aider ceux qui comme moi ...

  • Cannot ping host stale ARP cache?

    - by gkchicago
    I am having a strange issue with a Debian (Lenny/Linux 2.6.26-2-amd64) that has been driving me nuts. On some machines within my network I can ping the host in question just fine, other times I have to manually hard-code the ARP ethernet address for the IP in order to establish connectivity. I've finally worked it down to somehow involving ARP. I just found how to fix it in a way that made it work but I'm looking for help explaining this issue and also I don't trust my fix to be permanent.. My thought process has been the following but I just can't make any sense out of it: Could it be the card? (Intel 82555 rev 4) Could it be because there are two network cards? (Default route is eth0) Could it be because of the network aliases? Lenny? AMD x86_64? Argh..

  • email output of powershell script

    - by Gordon Carlisle
    I found this wonderful script that outputs the status of the current DFS backlog to the powershell console. This works great, but I need the script to email me so I can schedule it to run nightly. I have tried using the Send-MailMessage command, but can't get it to work. Mainly because my powershell skills are very weak. I believe most of the issue revolve around the script using the Write-Host command. While the coloring is nice I would much rather have it email me the results. I also need the solution to be able to specify a mail server since the dfs servers don't have email capability. Any help or tips are welcome and appreciated. Here is the code. $RGroups = Get-WmiObject -Namespace "root\MicrosoftDFS" -Query "SELECT * FROM DfsrReplicationGroupConfig" $ComputerName=$env:ComputerName $Succ=0 $Warn=0 $Err=0 foreach ($Group in $RGroups) { $RGFoldersWMIQ = "SELECT * FROM DfsrReplicatedFolderConfig WHERE ReplicationGroupGUID='" + $Group.ReplicationGroupGUID + "'" $RGFolders = Get-WmiObject -Namespace "root\MicrosoftDFS" -Query $RGFoldersWMIQ $RGConnectionsWMIQ = "SELECT * FROM DfsrConnectionConfig WHERE ReplicationGroupGUID='"+ $Group.ReplicationGroupGUID + "'" $RGConnections = Get-WmiObject -Namespace "root\MicrosoftDFS" -Query $RGConnectionsWMIQ foreach ($Connection in $RGConnections) { $ConnectionName = $Connection.PartnerName.Trim() if ($Connection.Enabled -eq $True) { if (((New-Object System.Net.NetworkInformation.ping).send("$ConnectionName")).Status -eq "Success") { foreach ($Folder in $RGFolders) { $RGName = $Group.ReplicationGroupName $RFName = $Folder.ReplicatedFolderName if ($Connection.Inbound -eq $True) { $SendingMember = $ConnectionName $ReceivingMember = $ComputerName $Direction="inbound" } else { $SendingMember = $ComputerName $ReceivingMember = $ConnectionName $Direction="outbound" } $BLCommand = "dfsrdiag Backlog /RGName:'" + $RGName + "' /RFName:'" + $RFName + "' /SendingMember:" + $SendingMember + " /ReceivingMember:" + $ReceivingMember $Backlog = Invoke-Expression -Command $BLCommand $BackLogFilecount = 0 foreach ($item in $Backlog) { if ($item -ilike "*Backlog File count*") { $BacklogFileCount = [int]$Item.Split(":")[1].Trim() } } if ($BacklogFileCount -eq 0) { $Color="white" $Succ=$Succ+1 } elseif ($BacklogFilecount -lt 10) { $Color="yellow" $Warn=$Warn+1 } else { $Color="red" $Err=$Err+1 } Write-Host "$BacklogFileCount files in backlog $SendingMember->$ReceivingMember for $RGName" -fore $Color } # Closing iterate through all folders } # Closing If replies to ping } # Closing If Connection enabled } # Closing iteration through all connections } # Closing iteration through all groups Write-Host "$Succ successful, $Warn warnings and $Err errors from $($Succ+$Warn+$Err) replications."

  • Should I use C style in C++?

    - by c.hughes
    As I've been developing my position on how software should be developed at the company I work for, I've come to a certain conclusion that I'm not entirely sure of. It seems to me that if you are programming in C++, you should not use C style anything if it can be helped and you don't absolutely need the performance improvement. This way people are kept from doing things like pointer arithmetic or creating resources with new without any RAII, etc. If this idea was enforced, seeing a char* would possibly be a thing of the past. I'm wondering if this is a conclusion others have made? Or am I being too puritanical about this?

  • Synching folders other than the default Ubuntu One folder doesn't seem to work on Windows

    - by Gordon
    I have installed Ubuntu One on two machines - one Windows 7 and one Windows XP. I have added a folder from the computer using the "Add Folder" button on the Windows 7 machine. The Ubuntu One dialog box tells me that file synch is finished and up to date. I now have two problems. If I log on to my Ubuntu One account on the web, I can see what appears to be a LINK to the synched folder - I cannot open the folder and see the contents. This is what I see in the Files page of my Ubuntu one account: ~/Documents/Computing/Test On the second machine, after synching is complete, I see the folder but NOT the contents. The folder is EMPTY. Can anyone provide a solution as to a) what is happening and b) how do I get this folder to synch properly on the other locations?

  • How to advocate Stack Overflow at work

    - by Gordon
    I am thinking of doing a short presentation at work about using Stack Overflow as a resource for your day job. What is the experience doing this? Would you deem it a valid resource to tell you colleagues about or is it similar to telling them about Google as a resource? Is there a better way of doing it? I was leaning toward asking questions side of Stack Overflow rather than answering them to avoid you-shouldn't-be-doing-this-on-work-time argument. Just as a follow up. Originally I didn't want to make the question to specific to my own case. My presentation will only be a quick four minute talk, which I will repeat over an hour to different groups. I may ask a question before the talk on Stack Overflow and refer to it during the presentation. Hopefully I will get some activity during the hour. I am also going to talk briefly about some of the other Stack Exchange sites that would fit the audience as they are not all developers. I think Super User, Server Fault and Programmers should work well. I will not be doing the presentation for another couple of months as it has be rescheduled, but I will update on how I got on.

  • Bind9 fails to start

    - by Gordon McIntosh
    After 3 weeks of trying to diagnose a failure of bind9, to start I have to admit I need assistance. Initially it was running correctly and when I made a modification to a bind file and re-run it an error msg came back rndc: 127.0.0.1#953 bind9 start fail It also fails to start on any other bind9 upgrade or required pkg. grep on mysql returns nothing now even if it is running, and dig on 127 only works when I have my phone connected as a modem. I don't have any more diagnostics that I know of, so some help would be appreciated as development has stopped.

  • Do Spambots have access to unlimited IP addresses?

    - by Reg Gordon
    I have been attacked for weeks by the same spambot trying to brute force the login page. I have a login security module now installed on my Drupal 6 website and it bans on IP after x amount of attempts. It's been going on for ever and I have banned about 1000 IP addresses. Is there any point in me banning on IP due to the spambot having access to unlimited IP addresses or will they run out of them eventually?

  • Everything turning black when pitching down

    - by Gordon
    Just a quick questions about something that's occurring in my world. Every time I pitch my camera downward, everything starts turning black, and if I pitch upward, everything sort of intensifies. I'm multiplying my normals by the normal matrix in the shader, and I'm multiplying my lights direction by the model view matrix. If I leave the normal and light dir in world space everything ends up fine. I thought putting them both in view space would not cause those weird things to happen?

  • Using jQuery.UI CSS Framework for DIV Styling

    - by Gordon
    Hi folks, a Project I am currently working on uses the jQuery UI framework for some of its widgets. To provide the user with a global look and feel I would like to use the framework also for its css stuff. I am implementing at the moment a dashboard like homepage, where the user can see an overall status of its data. This dashboard is build of some divs that should be aligned into a grid layout. I try to style the divs like follows <div class="ui-widget"> <div class="ui-widget-header">Box Header</div> <div class="ui-widget-content"> Content of the Box </div> </div> Later I would like to implement some draggable-and-sortable functionality. The Problem I am facing right now is that the boxes aren't properly aligned. Does anyone has a hint on using jQuery.UI for that kind of css work? I was studing the CSS framework documentation on jqueryui.com but there aren't that much information. best regards, Gordon

  • In Ruby, how to implement global behaviour?

    - by Gordon McAllister
    Hi all, I want to implement the concept of a Workspace. This is a global concept - all other code will interact with one instance of this Workspace. The Workspace will be responsible for maintaining the current system state (i.e. interacting with the system model, persisting the system state etc) So what's the best design strategy for my Workspace, bearing in mind this will have to be testable (using RSpec now, but happy to look at alternatives). Having read thru some open source projects out there and I've seen 3 strategies. None of which I can identify as "the best practice". They are: Include the singleton class. But how testable is this? Will the global state of Workspace change between tests? Implemented all behaviour as class methods. Again how do you test this? Implemented all behaviour as module methods. Not sure about this one at all! Which is best? Or is there another way? Thanks, Gordon

  • IPv6: Can't ping anything - "Operation not permitted"

    - by Matthew Iselin
    I've been working on getting IPv6 support into my network, and had everything working properly for a short while. The server is running Ubuntu Server 8.10. Now however whenever I attempt to do anything related to IPv6 on the server, I get "Operation not permitted". This is coming from things like wide-dhcpv6-client (when trying to get an IPv6 address from the ISP) and radvd - both log errors of this type into syslog. Even pinging the loopback interface fails: xxx@gordon:~$ ping6 ::1 PING ::1(::1) 56 data bytes ping: sendmsg: Operation not permitted ping: sendmsg: Operation not permitted ping: sendmsg: Operation not permitted ^C --- ::1 ping statistics --- 3 packets transmitted, 0 received, 100% packet loss, time 2014ms xxx@gordon:~$ sudo ping6 ::1 sudo: unable to resolve host gordon PING ::1(::1) 56 data bytes ping: sendmsg: Operation not permitted ping: sendmsg: Operation not permitted ping: sendmsg: Operation not permitted ^C --- ::1 ping statistics --- 3 packets transmitted, 0 received, 100% packet loss, time 2014ms As you can see, I have attempted pinging as root, as most of the material I've found on the internet points to a permission problem. However, that has not helped. Any hints to getting unstuck would be appreciated.

  • i5 540M or i7 720QM for laptop running VMs and software development tools?

    - by Donald Hughes
    I'm a software developer that would primarily be running Windows 7 as the primary operating system. On a typical day, I might, at any given moment, be running Visual Studio, Expression Web, SQL Server developer (and Management Console), IIS, Photoshop, a dozen browser tabs in 2-3 different browsers, Skype video chat, streaming music, and a couple of VMs (WinXP and Ubuntu) for testing/experimentation. Obviously, RAM is a concern, which is why I plan to use 8 GB so I can devote enough to the VMs to be usable. I'm also tempted to use an ExpressCard SSD for storing the VM disks to ease disk contention. And I know that that is asking a lot from a laptop, and I should just use a desktop, but I need to be able to take my work with me between several locations. It seems that at a reasonable price point, it comes down to the i5 540M versus the i7 720QM. I'm leaning toward the i7 since it would allow me to dedicate a whole hyperthreaded core to each VM, and still have two cores left for the primary OS. I've heard that the i5 has better battery life, but I'm curious for my scenario if there would be a meaningful difference. I don't usually work without a plug, but I do occasionally ride the train or fly and it would be nice to have at least 3 hours of juice for unusual circumstances. And, finally, for this usage scenario, would a dedicated video option be preferred over the i5's integrated video? It sounds like Visual Studio 2010 (and Windows 7) can take advantage of the video card.

  • Launch ubuntu software center from gnome shell

    - by Daniel Hughes
    I have been playing around with Gnome Shell from ubuntu 9.10. I installed the preview which is available in Ubuntu 9.10 repositories using sudo apt-get install gnome-shell gnome-shell --replace However I can't figure out how to launch Ubuntu Software Center using it. It just appears to be missing. The software center appears fine in normal gnome. How do you launch the Ubuntu Software Center from Gnome Shell. For those of you who are getting confused, Gnome Shell is the next generation user interface for gnome, it is planned for inclusion as default in Gnome 3.0, there is a preview of it in the Ubuntu 9.10 repositories. I am not interested in how to launch Ubuntu Software Center from the terminal or in how to launch it from the normal gnome interface.

  • Why are my 2 new windows 7 (64 bit) workstations taking over 10 minutes to log on to the SBS 2008 do

    - by Howie Hughes
    Hi, we have a SBS 2008 domain. On this we have windows XP clients. However, we are testing the windows 7 (64 bit) machines on the network. It takes between 10 & 15 minutes to log on - every time! I have checked the event logs on the client machine, and the only error I can see is; Event ID: 6005 The winlogon notification subscriber is took 615 seconds to handle the notification event (CreateSession). I have no warnings in the server event log, everything pings ok by name, so am guessing DNS is fine. Can someone please lend a hand with this, as we really want to go with windows 7. Lastly, both the server, and the windows 7 machines are fully patched and updated. Thank you.

  • Getting 400 Bad Request when requesting by server name on nginx/uwsgi

  • Is RAID 0 or JBOD better for home media server?

    - by Donald Hughes
    I have an external two-bay drive enclosure (the OWC Mercury Elite-AL Pro) connected to a Mac Mini (my home media server) over FireWire 800. I'm streaming media to other computers in the house over wired gigabit. I have two 1.5 TB drives that I'm using independently right now. The media is on one, and I'm mirroring the files to the other drive at night as a backup. But as I approach filling up the drive I'm wanting to span those two drives together to give me a total of about 3 TB, and then buy another drive for backups. The external enclosure supports both RAID 0 and JBOD, but I'm not clear on which would be better in this situation. Would RAID 0 provide any performance improvements over JBOD for streaming video (possibly several streams at once? How does each affect the MTBF of the drives? In general, should I choose RAID 0, JBOD, or keep them independent?

  • What would I need to do to clone a Linux install to another machine?

    - by Marcus Hughes
    Basically, I want to make an image of one Linux install I have, and distribute it over similar (if not identical) spec machines on a network. I know it is possible, however am unsure of what needs to be done before I make the image of the install to ensure it works correctly on all machines. First think I know needs to be done, is remove all interface configuration, as I assume it would just jump to eth1 (and possibly use the same MAC), as it wont locate the network interface it had before, how would I do this so it auto detects and goes to eth0 again? Is there anything else I would need to do to the install before I make its image?
