• Video Hosting External or Internal?

  - by user69334

  I have a client who wants to offer videos for downloading or streaming on his website. Now we have hosting for him, which is wonderful: it's reliable and fast, offers unlimited space and databases BUT it only offers 10GB in bandwidth. The videos could easily be placed on his server (unlimited space) but the bandwidth is a real problem. Now I am wondering if he would purchase external hosting for his videos, and people would want to download them, woould this still eat up all his available bandwidth in no time, because the download request would go via his site, or is there a way to circumvent this?

• Software to draw custom street maps?

  - by jay

  I'm looking for any (Windows) software that allows me to draw custom street maps. I'm not looking for something that displays existing maps from real places, but something that allows me to define my own map. Obviously this can be achieved through any graphics program however I am wondering if there's a software which makes it almost drag-drop easy to create your own maps of visual quality to that of Open Street Maps, Google Maps, street directories etc. Preferably an offline desktop app with attention on design rather than complex geospacial specifics. Context: I want to make a detailed street map for a game I'm making.

• Vertical alignment problem in textbox in Microsoft Word 2007

  - by Surjya Narayana Padhi

  I pardon as its not a programming question at all. But if anybody can answer this it will be usefull for me. In MS word 2007 I drew a textbox and entered some text. Then I right clicked on textbox and went to format shape Then went to TextBox tab and reduced the top internal margin to 0.1 cm. But still it seems there is too much space at the top inside the textbox. I am not able to position the text exactly at the vertical middle of textbox. If I choose the auto-rezide option in format Shape, the textBox size is increases automatically but the text remains exactly at vertical and horizontal middle of textbox. but anyhow I need the textbox to be small. This is very minor but annoying problem. Can anybody help?

• Booting Windows7 kernel from an initrd/wim image file

  - by Ivo

  I'm wondering if it's possibile to have Win7 kernel and relative drivers (especially storage drivers) to boot from an initrd-like image file (maybe .wim?) and later then mount the windows root partition and complete the load of the full OS? I'll try to explain why: I'm running an emulated environment with NO REAL BIOS, and I'm passingthrough a raid storage controller. I want windows to boot from this controller array, but of course the BCD manager cannot access disks in the array until kernel and relative controller storage drivers are loaded. To be clear I get the classical winload.exe missing error. I need a similar solution to what Linux does, loading the kernel and his drivers, and later then mount the root partition and complete the boot. Any ideas or advices?

But there is no any memory problems reported in munin monitoring: As you see system uses around 0.2G and 1G is available. So my question is: Is it xen specific problem, that real memory usage and memory usage that shows munin are different (I've never seen such problems oh real hardware machines)? Or maybe it is just monitoring problem, that can't catch moment when there is unusual high load and domU go down? And how I can to defeat this problem? it is really annoying to catch messages in e-mail that domU went down. Btw, such situation was when domU had 2G memory.

• notebook display problem

  - by kpower

  I have RoverScan Voyager notebook. It worked good for a few months. But some day I turned it on and saw that it displays badly. I mean, picture that should be displayed by monitor is copied six times and displayed on screen (6 same small pictures, not crossed each other). And the picture itself is bad - it displayed as interchange of vertical lines (it's really hard to see real picture or distinguish some details on it - it is distorted badly). Can you suppose, what's the reason? And what can I do to solve the problem?

• Is it possible to add an existing Azure VM to an Azure Virtual Network?

  - by Dan Harris

  Didn't think this was directly related to programming, so thought Superuser would be better than Stack Overflow.... Is it possible to add an existing Azure VM to an Azure Virtual Network if you didn't add it to the virtual network at the time of creation? I can't see an option to change which Virtual Network the VM is connected to. Do you just have to do it at the time you create the VM, and if you don't do it then you will need to re-create the VM and delete the existing one? Example of the scenario: No VM's or Virtual Networks exist I create a VM (VM1), there is no virtual network so it isn't added to one Later I create a Virtual Network in Azure (Network1) It is possible to create another VM (VM2) and connect it to the Virtual Network (Network1), but can I connect VM1 to Network1 or must I delete VM1 and re-create it to get it connected to Network1?

• Why does 1GBit card have output limited to 80 MiB ?

  - by Gallus

  I'm trying to utilize maximal bandwidth provided by my 1GiB network card, but it's always limited to 80MiB (real megabytes). What can be the reason?

• Ubuntu 12.04 VPS doesn't boot with mysql in nsswitch.conf

  - by chrisv

  1and1 VPS ("dynamic cloud server") does not boot any more as soon as mysql lookup is enabled in nsswitch.conf - any suggestions appreciated. Minimal setup to reproduce the problem: install Ubuntu 12.04 / LTS minimal server image install mysql-server, libnss-mysql-bg, nscd configure /etc/libnss-mysql.cfg and /etc/libnss-mysql-root.cfg set up appropriate database tables configure nss lookups through mysql in nsswitch.conf passwd: compat mysql group: compat mysql shadow: compat mysql Now, when I try to reboot the server it just hangs. No logs (maybe due to /var not yet being mounted), and I can't see console output (since this is a VPS). Booting into recovery image and removing "mysql" from /etc/nsswitch.conf makes the system bootable again, so this is definitely related to nsswitch/libnss-mysql-bg. There's a thread on gentoo-users which seems to describe a similar problem, unfortunately there's no real solution described, also the thread is rather old (from 2006) so I'm not sure whether this applies to me at all.

• A website hosted on the 1.0.0.0/8 subnet, somewhere on the Internet?

  - by Dave Markle

  Background I'm attempting to demonstrate, using a real-world example, of why someone would not want to configure their internal network on the 1.0.0.0/8 subnet. Obviously it's because this is not designated as private address space. As of 2010, ARIN has apparently allocated 1.0.0.0/8 to APNIC (the Asia-Pacific NIC), who seems to have begun assigning addresses in that subnet, though not in 1.1.0.0/16, 1.0.0.0/16, and others (because these addresses are so polluted by bad network configurations all around the Internet). My Question My question is this: I'd like to find a website that responds on this subnet somewhere and use it as a counter-example, demonstrating to a non-technical user its inaccessibility from an internal network configured on 1.0.0.0/8. Other than writing a program to sniff all ~16 million hosts, looking for a response on port 80, does anyone know of a directory I can use, or even better yet, does anyone know of a site that's configured on this subnet? WHOIS seems to be too general of a search for me at this point...

• Environment variables in Weblogic Managed Server with SSL nodemanager

  - by Eric Darchis

  We have a C legacy application start with JNI that requires environment variables. Not java -Djava.library.path -Dvar=foo as these are purely java. I need real environment variables. When we setup our domains, we usually use the SSH method to start the node managers. This works fine and the env variables are set properly. Recently the sysadmin has decided for a few reasons to use the SSL mode for nodemanagers. The servers start but the environment variables are not set. I checked with "pargs -e" (this is a Solaris machine) that the env variable was indeed not present from the nodemanager and for the managed server. Is SSL starting the managed server without running the .sh scripts or I am missing a parameter somewhere ?

• Disk space mismatch on OS X Server (Leopard)

  - by John Gardeniers

  My Nagios system sent me an alert to inform me that the disk space on one of the drives on our OS X server is very low. When I run df /Volumes/Apps/ I get /dev/disk0s3 117209520 114932472 2277048 99% /Volumes/Apps When I run du -c /Volumes/Apps it reports 11489944 total Why might there be such a vast difference? Even more importantly, how do I find the problem and what can I do about it? I'm essentially just a Windows admin, so am well out of my comfort zone here. I use a Mac but I'm not a Mac admin in any real sense of the word.

• Java application crashes on startup in citrix session

  - by Brimstedt

  Hello We have a java application published through citrix. When application is launched for a new user, it crashes immediately on startup. If we login using RDP, then log out (not starting the app), it starts to work. We've published another smaller java app, and it works for new users, without the need to first log on using RDP. Steps: - Publish java app - create new user - run published app in citrix -> crash - log on user using rdp, log out - run published app in citrix -> works fine Its becoming real tiresom to log on each new user to each citrix server :-P

• How can I include guidance text in Word?

  - by gf131072

  We use several Word documents as templates and currently include 'guidance' text for the reader - in the form of grey, italic text - to provide guidance to the person completing the document. Note how the grey+italic text is used to provide both guidance and example content Problems with this approach include: People forgetting to delete all of this template/boilerplate text People using the italic+grey formatting when inputting real information because they don't change the style We've considered including Reviewing comments as an alternative but this can be a pain and suffers from the first problem above. I'm not sure a simple, elegant solution exists here but if there's something obvious I'm missing I'd love to hear about it.

• How can I make full-screen desktop applications only cover the snapped desktop?

  - by nhinkle

  In Windows 8, you can "snap" two apps next to each other, and one of those apps can be the legacy Windows desktop environment. A convenient application for this (or so I thought) would be to snap a chat client, small browser, or other app while watching content in full-screen on the desktop. The problem with this is that full screen desktop applications will take over the entire screen, even if the desktop is snapped to only occupy 3/4th of the display. What I would like is some way to force "full screen" desktop apps to only cover the snapped desktop area, and to truly go full screen if the desktop is snapped to full-width. Is there some way to configure this? If that didn't make sense, let me illustrate with pictures: Desktop in snapped view with SU chat in mini-browser: What happens when you click "full screen": What I want to happen when I click "full screen" (note this is digitally altered, not a real screenshot)

  I have some software that required e.g. .NET 4 install before them. I wonder what is the best way to make a GPO order list. I also have some software that needs certain files so I need to prepare them (via batch file). I have done a quick research however I haven't found the answer. Any help, link would be appreciated. Please feel free to down vote it if it is a real dummy one. Thanks for example: batch file cleans some folder install .NET Framework 4 install apps through MSI (commercial software) I can't pack everything in the MSI and I also need to make sure that all the steps succeed

• Best Guest OS for running freeswitch under Proxmox

  - by Frank Waller

  We have a lot of asterisk Systems running on dedicated machines and would like to use freeswitch to replace a number of them. One of the advantages of freeswitch is supposed to be that it is doing much better in a virtualized environment than asterisk is. However I can find very little information about people using it in Proxmox containers. I would like to know if anyone has seen any ready to run proxmox images that include freeswitch so we can test a number of things without having to deeply go into creating our own. Or at least a clue to which system images/distro images we can use to quickly get it installed not having to deal with too many dependency or different Linux version issues. Just to be clear: It should be for a more or less current Proxmox and current freeswitch. I am not looking forward to use the KVM mode but would consider it, if it is otherwise ready to run out of the box. I would rather use a real OpenVZ based container. Thanks for anyone helping!

• perfmon reporting higher IOPs than possible?

  - by BlueToast

  We created a monitoring report for IOPs on performance counters using Disk reads/sec and Disk writes/sec on four servers (physical boxes, no virtualization) that have 4x 15k 146GB SAS drives in RAID10 per server, set to check and record data every 1 second, and logged for 24 hours before stopping reports. These are the results we got: Server1 Maximum disk reads/sec: 4249.437 Maximum disk writes/sec: 4178.946 Server2 Maximum disk reads/sec: 2550.140 Maximum disk writes/sec: 5177.821 Server3 Maximum disk reads/sec: 1903.300 Maximum disk writes/sec: 5299.036 Server4 Maximum disk reads/sec: 8453.572 Maximum disk writes/sec: 11584.653 The average disk reads and writes per second were generally low. I.e. for one particular server it was like average 33 writes/sec, but when monitoring in real-time it would often spike up to several hundreds and also sometimes into the thousands. Could someone explain to me why these numbers are significantly higher than theoretical calculations assuming each drive can do 180 IOPs? Additional details (RAID card): HP Smart Array P410i, Total cache size of 1GB, Write cache is disabled, Array accelerator cache ratio is 25% read and 75% write

• How to correctly set up iWARP? Preferably on loopback

  - by ajdecon

  iWARP is a protocol for doing remote direct memory access (RDMA) on top of TCP/IP, so that it can work with Ethernet and other network types as opposed to Infiniband. It works with many of the standard IB interfaces - the IB verbs, for example - so it's all pretty transparent. I'm doing some IB-verbs programming (mostly for the sake of learning about how they work better), and it'd be wonderfully convenient for me if I could use iWARP to do RDMA over my loopback interface, so that I could test some of my code without getting on our IB-connected cluster. :-) But I cannot figure out how to get a "local development environment" set up: there are no tutorials I'm aware of for even setting up iWARP from scratch on a server or a network interface. Can anyone give me a tutorial or point me in the right direction? Environment is Fedora 16 running in VirtualBox.

• What Windows licenses are required to run additional terminal service sessions

  - by John P

  We need to build out a server running Windows 2008 R2 Standard that can allow up to 10 simultaneous RDP/Terminal Services connections and I'm a little confused about how the CAL licenses work. From one source I was told I needed 10 "server CALs" and an additional 10 "RDP CALs" (total of 20 CALs). From another, I was told I just needed the 10 "RDP CALs", which implicitly came with the server CAL. The Microsoft licensing website (http://www.microsoft.com/windowsserver2008/en/us/licensing-rds.aspx) seems to support scenario #1, but it is still not real clear what those server CALs are needed for. Also, can we use the 2 "built-in" RDP clients, meaning we only need to purchase 8 CALs to reach a total of 10?

• How to prove that an email has been sent?

  - by bguiz

  Hi, I have a dispute on my hands in which the other party (landlord's real estate agent) dishonestly claims to not have received an email that I truly did send. My questions is, what are the ways to prove that the email was indeed sent? Thus far, the methods that I have already thought of are: Screenshot of the mail in the outbox Forwarding a copy of the original email I am aware of other things like HTTP/ SMTP headers etc that would exist as well. Are these useful for my purposes, and if so how do I extract these? The email in question was sent using Yahoo webmail ( http://au.mail.yahoo.com/ ). Edit: I am not seeking legal advice here, just technical advice as to how to gather this information.

• HDFS datanode startup fails when disks are full

  - by mbac

  Our HDFS cluster is only 90% full but some datanodes have some disks that are 100% full. That means when we mass reboot the entire cluster some datanodes completely fail to start with a message like this: 2013-10-26 03:58:27,295 ERROR org.apache.hadoop.hdfs.server.datanode.DataNode: java.io.IOException: Mkdirs failed to create /mnt/local/sda1/hadoop/dfsdata/blocksBeingWritten Only three have to fail this way before we start experiencing real data loss. Currently we workaround it by decreasing the amount of space reserved for the root user but we'll eventually run out. We also run the re-balancer pretty much constantly, but some disks stay stuck at 100% anyway. Changing the dfs.datanode.failed.volumes.tolerated setting is not the solution as the volume has not failed. Any ideas?

• String manipulation of type String substitution in mathematical expression

  - by Peterstone

  Imagine something like exp(49/200)+(x-49/200) I want to pass as argument of the function "roundn" whatever operation that is not a addtion or a subtraction So my expresion became roundn(exp(roundn(49/200,n)),n)+(x - roundn(49/200,n) Well the expression I want to manipulate is this: exp(49/200)+exp(49/200)*(x-49/200)+1/2*exp(49/200)*(x-49/200)^2+1/6*exp(49/200)*(x- 49/200)^3+1/24*exp(49/200)*(x-49/200)^4+1/120*exp(49/200)*(x-49/200)^5+1/720*exp(49/200)*(x-49/200)^6+1/5040*exp(49/200)*(x-49/200)^7+1/40320*exp(49/200)*(x-49/200)^8+1/362880*exp(49/200)*(x-49/200)^9+1/3628800*exp(49/200)*(x-49/200)^10+1/39916800*exp(49/200)*(x-49/200)^11 I´m looking for a method (That include whatever program) not based in lenguage programming, as much batch or somithing like that... Thank you!
