  • Book Review: Getting Started With Window 8 Apps By Ben Dewey

    - by Tim Murphy
    When O’Reilly gave me an opportunity to review this book I was excited.  It gave me a reason to finally put some time into this new platform and what developers will need to learn in order to be successful. This book by Ben Dewey is only 92 pages long, so if you were looking for an in-depth treatment of Windows 8 development you will need supplemental materials.  It is also due for an update from the perspective of recent changes made by Microsoft prior to the final release of the OS and tools.  This causes a few issues if you try to run the code samples because of namespace changes. I was encouraged by the fact that the author didn’t do the typical “hello world” app.  He uses a lot of pattern based development techniques and hits many of the main topics including: Application lifecycle Charms integration Tiles Sensors The lifecycle is critical for anyone who hasn’t done mobile development before.  Limited resources on these devices mean that the OS can suspend or kill your app altogether if it decides it needs to.  He covers tombstoning which is the key to Windows 8 and Windows Phone lifecycle management. He also dedicates a chapter to marketing and distributing the application you build.  From my experience with Windows Phone development this is crucial information.  You need to know how to test your application so that it is going to pass certification and present your app so that it is going to get noticed amongst thousands of other apps. The main things that I wish had been in the book explanations of more of the common controls and more complete explanation of patterns that were implemented. In the end this book is a good foundation getting exposure to the concepts that underlie this new version of the Windows platform and how it effects developers.  It isn’t a book that I would suggest for someone just getting into development with no understanding of pattern based development. del.icio.us Tags: Windows 8,O'Reilly,Ben Dewey,Book Review,Review

  • Cisco Catalyst 65XX and traffic shaping

    - by Nadz Goldman
    Hello! I have Cisco Catalyst 65XX, many VLANs and about ~1300 users. Users connected to some D-Link switches with second-level management. D-Link switches come to my Cisco Catalyst 65XX by VLANs. So, how I can shape traffic per user? If I use something like this: access-list 145 permit ip any host 192.168.0.1 access-list 145 permit ip any host 192.168.0.2 access-list 145 permit ip any host 192.168.0.3 ... int Gi0/1 traffic-shape group 145 128000 7936 7936 1000 will I have shape traffic per user or it will shape traffic only on interface? I mean - every user will have 128kb/s (per user) or everybody will have 128kb/s ? If it will be for everybody, then what is the solution of my question: how every user can have 128kb/s ?

  • PLESK Original php.ini files needed

    - by Saif Bechan
    Hello, I am using PLESK 9.2.3 with CentOS 5. I recently tried to change some things in the php.ini files, but i ended up clearing both files. stupid mistake! Is there a possibility i can get the content of both files back. I am talking about the files: /etc/php.ini /usr/local/psa/admin/conf/php.ini or was it /etc/php.ini /usr/local/psa/admin/conf/.php.ini When i browse to my PLESK panel i get the error message: Warning: Unknown: failed to open stream: No such file or directory in Unknown on line 0 Fatal error: Unknown: Failed opening required 'auth.php3' (include_path='.:') in Unknown on line 0 Thats as much information i can get, i hope someone can make some sense of all this Regrads EDIT: I ended up just reinstalling plesk which was fairly easy. Something like yum install psa-plesk. There was a guide i followed, and everything worked out ok

  • "Supervising" syslog-ng in htop

    - by djechelon
    Hello, I was working at my server, when in htop I just noticed something unusual. The syslog-ng process was listed as follows supervising syslog-ng /sbin/syslog-ng I don't know what it means. I tried to do man supervising but found nothing. supervising command doesn't exist too. Googling, I found a page about launchtool, but I can't find neither it or its man page in my system. I'm curious What does that executable/command/whatever do? Why today did I read that line in htop? Thank you. PS: I was unsure about posting this to SU or SF: even if it's a server-related question, it covers general Linux.

  • How to move 100mb hidden system reserved partition on Windows Server 2008 R2 to other drive?

    - by Artyom Krivokrisenko
    Hello! I have a server with two 1.5TB hard drives. I was going to install a Windows Server 2008 R2 and create software RAID1 using Windows Disk Management Utility. I instaleld Windows, open this console and that is what I see: http://i.imgur.com/KoC9a.png Setup program created a System Reserved Partition at my second HDD. I don't understand now, how can I create RAID1, because space, which supposed to be used for copy of disk C, now is used for this hidden partition. So is there any way now to create correct RAID1? May it is possible to move this partition to the Disk 0, where I have plenty of free space? Unfortunately I can't reinstall Windows and apply other options at the disk management step of the installation, because installation image is not longer connected to the server and I have no physical access to server, only remote desktop.

    Hello, I had a Linux centos(5.5) machine, on this i had deployed amavisd (with clamav and spamassassin).

  • How to go to a website on a shared server by its ip address?

    - by user1502776
    I have a few questions, please help: Fist, I can access google search just by typing http://74.125.224.211 because this is the ip address returned by nslookup. However, I could not do so with ip addresses returned from www.yahoo.com. How do I go to yahoo search page by its ip ? Another example, http://www.allaboutcircuits.com will resolve to 68.233.243.63 by DNS server, but if I go to http://68.233.243.63 I got "Hello world!" , lol ! Second, for some reason, there is something wrong with DNS resolvers with my web hosting service (it will not be fixed !!). So command like, get_file_contents("http://www.allaboutcircuits.com"); will return php_network_getaddresses: getaddrinfo failed: Name or service not known How do I get around this with IP address , 68.233.243.63 I mean somehow attach the HTTP hostname parameter to get_file_contents() ? I would like to solve this on my own side (in my code), no troubleshooting/adjustment will be done by server admin.

    - by Shaharyar
    Hello everybody We're just setting up a brand new Server 2008 R2 with Remote Desktop services. Everything is installed fine so far, we have set it up with 5 CALs per User (not Machine!) and they are activated and running. The problem / question here is: Is it possible to log in with the same user multiple times? This worked perfectly fine in Windows Server 2003 We just want it to start a new session on the server with the same user. Has anyone of you got experience in that? Thanks!

  • How to monitor CPU usage and performance on a Hyper-V server with several VM's

    - by Bjørn
    Hello, I have a server that is running Windows 2008 64 bit Hyper-V, with 8 gigs of RAM and Intel Xeon X3440 @ 2.53 Ghz, which gives me 8 logical cores in the performance monitor on the host system. I have set up three Virtual Machines, all running Windows 2008 32 bit. Build server, running Team City Staging server SQL Server, running SQL Server 2005 I have some troubles with the setup in that the host monitor remains responsive at all times, even though the VM's are seemingly working at 100% cpu and are very sluggish and unresponsive. (I have asked a separate question about that.) So the question here is: What is the best way to monitor how the physical CPU's are actually utilized? The reason I am asking is that I am being told that i cannot reliably use the task manager to monitor CPU usage in a VM.

  • Disabling horizontal scrolling using mouse wheel

    - by Carlos
    Hello, I am using Windows 7 x64 on an iMac (via BootCamp) with the button-less Magic Mouse that comes with the iMac. I would like to disable the horizontal scrolling that happens when you move slightly the finger horizontally while doing a vertical scrolling. In the Control Panel, Mouse section, Wheel tab, Horizontal Scrolling section, the minimum value that you can enter is 1, not 0. Is there a way (in the Registry) to disable horizontal scrolling using the mouse wheel? Or to set that value to 0 to see if it does the trick? Notice that this is a Windows specific question, not Mac OSX or Apple or Magic Mouse question, it can apply to any mouse in Windows whose wheel supports horizontal scrolling apart from vertical scrolling.

  • Linux accessibility: Slow Keys causing duplicate key strokes

    - by skypanther
    I'm exploring the accessibility features within Gnome and having trouble with Slow Keys. My input is always doubled. Press a key briefly and I get nothing as you'd expect. Press just a bit longer and which ever key I'm pressing is input twice. Hello becomes HHeelllloo. I'm running Debian Lenny 5.0.6, kernel 2.6.26-2-686, GNOME Desktop 2.22.3 running within a VirtualBox session. I did some googling and didn't find others having similar troubles. Maybe it's a vbox thing? Any ideas how to fix this so I don't get the duplicates? It makes it impossible to log back in when the screen lock kicks on!

  • Error: Failed to generate a user instance of SQL Server (again)

    - by Richard77
    Hello, I'm using: Vista SP2 Visual Studio 2010 professional edition SQL Server 2008 Express R2 Dev Server (Cassini) This question has been asked several times. Unfortunately, I didn't find yet an answer that exactly appropriate for me, so it's not possible to apply the solutions I find on the web. I find solutions for Win XP, 7, 2003, sql server 2005. But not for the above combination. I just don't why this problem started a couple days ago. I removed sql server and added it again, but no good result. Either an answer to the question or links to resources will be helpful. Thanks for helping.

  • Configuring and managing Windows web server

    - by Mike C.
    Hello, I run a few websites and I was thinking of paying for a dedicated Windows web server from GoDaddy instead of paying for each site's hosting individually. I know enough about IIS to configure the Host Header and stuff like that, but I'm a little fuzzy about the email portion of the hosting. I have a few questions: Do I need to install an SMTP server on the web server to allow for emails to be sent/received to a website email address? Or is there another approach that I'm unaware of? Are there tools that monitor the amount of bandwidth used by the server? GoDaddy charges for bandwidth and I want to make sure I don't go over. Am I opening a can of worms that I don't really want to open by going the dedicated server route? Things like server updates, security, etc? Thanks!

  • Folder Redirection - Explorer requires manual refresh

    - by Pete
    Hello, I am having an issue where - when a users my documents folder is redirected to a DFS share, windows explorer requires a manual refresh after creating a new folder, file, etc. (Interestingly, not when making a new briefcase) I have tried a number of MS knowledge base articles, a hot-fix and a registry change, all with no success. (( http:// support.microsoft.com/?kbid=823291 ; http:// support.microsoft.com/kb/873392 )) The problem only occurs when going through the my documents icon. If I map a home drive for the user to the exact same location (IE - H:\DFS\user\documents) , open that drive and make new folders, then there is no problem. Mapping my documents to H:\ also resolves the issue, however, as we need folder sync and people logging on off site with cached profiles this is not a workable solution (as H: will not map and there will be no access to their docs.) Has anyone managed to figure a fix for this? Thanks, Pete.

  • Accessing SQL Server over Workgroup

    - by Brian
    Hello, I have two machines: A: Win 2008 server B: Windows 7 They are on the same workgroup, and I enabled network discovery. So on the server, I have SQL Server installed with a SQL Server account (mixed mode is enabled). I'm trying to connect to this server from the win 7 machine in the workgroup, but no go. Do I have to reference the server by something else than machine name? How do I successfully establish that relation? I am a n00b to this type of thing... Thanks.

  • I started getting a weird message "Encrypting file system - Back up your file encryption key"

    - by user22559
    Hello I started getting a strange message when I start my computer. An icon appears in the system tray, and a popup tells me "Encrypting file system - Back up your file encryption key". I know what EFS is, but I don't use it. To my knowledge, I don't have any encrypted files on my partition. I have searched using Total Commander on all the partitions for files that have the "encrypted" attribute, but I found nothing. So I don't have any encrypted files. Does anyone know what I did to get this message?

  • On Server Disk Storage VS SAN Storage

    - by Justin
    Hello, I am looking at buying three servers, and trying to figure out which storage solution makes the most sense in terms of performance and cost. Total budget is around: $10,000. OPTION 1: Dell servers with RAID 10 (4 Drives) each 7200RPM SAS 500GB, for a total capacity of 1TB. Each server is approx: $3000. Total storage then across all three servers is 3TB. OPTION 2: Same Dell servers with a cheap single drive no RAID for $2000 and go with a centralized SAN solution. The biggest problem is that I haven't been able to even find a SAN solution that is a reasonable price. Dell entry level storage servers are like $15,000. I am thinking just iSCSI, not fiber (too expensive). What do you guys recommend?

  • Strange behavior of logRotate?

    - by superdario
    Hello, I have the following configuration of logrotate: /var/log/test/app.log { missingok notifempty compress copytruncate daily rotate 4 } The application generating the log is a Java application. 2 I set up this configuration yesterday before midnight. Today in the morning I noticed that logRotate made a file called "app.log.1", which only had log entries between 8:21 AM and 10:05 AM. app.log was logging since 10:05 AM. All the logs before 8:21 AM were missing! Furthermore, "app.log.1" wasn't even compressed. Do you know what could've caused this?

  • Yahoo sitemap validation

    - by Joel
    Hello, I am trying to submit sitemap.xml (index) to Yahoo Site Explorer but with no luck. I tried using website feed option in the site explorer to submit the sitemap, but I got validation errors. However, when submitting the same sitemap to google webmaster tools, the sitemap was validated successfully. Could it be for the fact that I am using sitemap with image tag: <image:image> <image:loc>http://www.domain.com/pic.jpg</image:loc> <image:title>picture</image:title> </image:image> When I tried validating the sitemap with inline tools such as http://www.xml-sitemaps.com/validate-xml-sitemap.html and http://www.w3.org/2001/03/webdata/xsv the error I received was: Attempt to load a schema document from http://www.google.com/schemas/sitemap-image/1.1 (source: new namespace) for http://www.google.com/schemas/sitemap-image/1.1, failed: Not recognised as W3C XML Schema or RDDL: html However, the declaration of the sitemap I use in the top of the document is the same as suggested by Google on their official page at http://www.google.com/support/webmasters/bin/answer.py?hl=en&answer=178636 : <?xml version="1.0" encoding="UTF-8"?> <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:image="http://www.google.com/schemas/sitemap-image/1.1"> <url> Any ideas how to resolve this issue?

  • Dell R510 vs R710

    - by AX1
    Hello, the Dell R510 and R710 can both hold regular configurations (e.g. X5650, 24 GB RAM, etc.) and these usually come out to about the same price. Is there a particular reason why one would choose the R510 over the R710 or vice versa? There really appears a lack of differentiating factors. The only 'major' factor I found, which doesn't apply to me though, is that the R510 can hold up to 12 3.5in HDDs while the R710 (which is slightly more expensive) can only hold up to 6 3.5in HDDs. Maybe you guys have some input and bought either of these machines (or both) to shed some light on other differences and why someone should choose one over the other as the pricing is pretty much the same with my configuration. Thanks!

  • Belkin Flip KVM keyboard skip problems

    - by Craig
    I have just bought a Belkin Flip 2 port KVM. Functionally it is almost there except I have a keyboard sticking problem. So if I type the word 'Hello' it will often (about 25% of the time) output 'Hellooooooooooooooooooooo'. If I plug the keyboard directly into the USB on the computer I don't have this problem, only when plugged into the KVM. I feel like it is a USB speed problem. Followup It appears I have the same problem with the mouse, it will jump from one side of the screen to the other as I move it. The mouse is annoying but half as much as the keyboard.

  • CPU's on Hyper-V host system is just idling, even though VM's are at full throttle

    - by Bjørn
    Hello, I have a server that is running Windows 2008 64 bit Hyper-V, with 8 gigs of RAM and Intel Xeon X3440 @ 2.53 Ghz, which gives me 8 logical cores in the performance monitor on the host system. I have set up three Virtual Machines, all running Windows 2008 32 bit. Build server, running Team City Staging server SQL Server, running SQL Server 2005 These three machines are running very sluggishly, they are at 100% cpu even though the host system is barely using any cpu at all, typically below 10% total. Could anyone please give some tips as to the best setup for CPU allocating? Should I have set each server to have two cores, or should I increase this number above the total number of cores on the host? What is a good number to set on the Virtual Machine Reserve and Virtual Machine Limit? Is 8 gigs of physical RAM insufficient for 3 VM's? Thanks for reading. :)
