  • Mirror virtualized development environment

    - by David Casillas
    I work alone in some iOS projects in a local environment. I have been thinking in a way to be able to share my development environment between my Mac Mini and my MacBook. I mostly work at home in the Mini but sometimes I need to do a demo or work outside and I would like to have the development environment mirrored in both. I have think in using a virtual machine (via VirtualBox) with just my development tools instaled. Then I could synchronize that VM with some software between both computers so I will always have the exact environment no matter what computer I use. Is there any good reason not do do this way? I have not used Virtualization to much so I have no background on the subject. My basic setup will be: Mac Mini: i7 dual Core, 8Gb. OSX Mountain Lion Host OS: MacBook: 2.4 Core 2 Duo. 4Gb. OSX Lion Host OS. Virtual Box with Mountain Lion guest OS in both machines. XCode5, Simulator.

  • Why no "da-doomp" (disconnect notification sound) sometimes when unplugging wireless mouse receiver?

    - by DanH
    Sometimes (maybe one case in 3), when I unplug the wireless mouse receiver on my Sony VGN-CS215J laptop, there is no "da-doomp" sound, even after a minute or two. And if I plug the receiver back in there is no corresponding "du-dump" sound and the mouse is still (immediately) "live". This can happen when the activity light is out and there's nothing obviously going on -- it's not simply that the box is too busy. Other times one gets the expected behavior (and usually I get the correct behavior if I plug the receiver back in a few seconds and then unplug it after a "failure"). The reason this is significant is that if I get no "da-doomp" then the laptop will not sleep properly -- it will go to sleep initially, but then reawaken a few minutes later inside my laptop case and proceed to run the battery down (and no doubt overheat the unit). Any ideas?

  • Domain DNS Lookup time

    - by Maxim Dsouza
    I have a website hosted at www.doondoo.com. The site when loaded in the browser for the first time, takes a bit of time to load. It looks like the DNS lookup takes a lot of time. Once the site is loaded on the browser, other pages load very quickly. The application is hosted on Linode and I have pointed my domain to the nameservers of Linode i.e ns1.linode.com and ns2.linode.com I wanted to know what is the reason behind this delay in the loading. And what could be the possible means to improve it. Thanks in advance.

  • Building RPM containing passwords

    - by Kuf
    I need to be able to send an RPM to customers that will install the complete server, including Apache and MySQL. The customers will install it on a clean machine. After installation, the server should connect to our main DB, so I though of including the password in the RPM somehow, encrypted if possible. The reason I'm asking this is because I'm pretty sure that it's not wise to save the password in the rpm scripts. I was hoping that someone else had a similar problem and managed to solve that somehow. If anyone knows a way to do that, or have a better idea please share!

  • Clone remote CentOS server to local test server?

    - by dannymcc
    We have a dedicated server running ContOS 5.5. The server runs our Magento store and a basic php website with mysql. I have a spare rack server in my office (HP ProLiant DL360 G4) that has more than enough storage space to store a duplicate of our dedicated server. I would like to clone the dedicated server entirely and have a local duplicate. It wouldn't need to be kept in sync because I can do that with GIT. The reason I want to do this is simple; learn more about the dedicated server and CentOS. Is this possible? I have SSH access to the dedicated server and obviously complete access to the local server.

  • Linksys WRT54G2 not showing connected PC's in DHCP table

    - by Moose
    For some reason all of a sudden my linksys WRT54G2 no longer shows PC's connected in the DHCP table. It was being touchy then all of a sudden they all just disappeared. It showed 2 of the 4 connected then it showed the other 2 then it only showed 1 and then it was showing none. I seem to be having a connection reset every 30-60 minutes also not sure if that is related to the router going bad or if it is just comcast being it's typical crappy self. I have tried to reset my router and my cable modem and both problems still seem to keep happening(no PC's in table and connection reset every 30-60 mins). Now I know the router doesn't store clients after a router reboot but they normally show up within a matter of minutes for me in the past. Before anyone asks yes all devices on the network are using DHCP and not static. Could this be a sign of the router starting to go bad?

  • rdesktop for windows?

    - by Claudiu
    I'm looking for a good RDP client for Windows. The built-in one for WinXP doesn't do sound and puts black padding around the window for some reason. Something like rdesktop would be perfect. I've tried getting it to run on windows, but I've run into problems. Even though I had XminG running as an xserver, it said it couldn't connect to the local display. Eventually I installed x/cygwin and compiled rdesktop myself, and that ended up working, but the sound still didn't work. Is there any good rdesktop-like client for windows, or a stand-alone version that wouldn't require installing x/cygwin and compiling just to work?

  • SQL SERVER – Simple Installation of Master Data Services (MDS) and Sample Packages – Very Easy

    - by pinaldave
    I twitted recently about: ‘Installing #sql Server 2008 R2 – Master Data Services. Painless.‘ After doing so, I got quite a few emails from other users as to why I thought it was painless. The reason was very simple- I was able to install it rather quickly on my laptop without any issues. There were a few requests along with these emails sent to me, which regards to how to install MDS, as well sample databases. Please note that I am the admin of my machine and I installed this MDS as the admin as well. Talk to your network administrator to figure out the best suitable settings for better security of login users. Additionally, since MDS is only supported on a 64-bit machine, I had rebuilt my computer a week before with a 64-bit OS and 64-bit SQL Server to go with it. Here is a quick picture tour of the installation. First of all, go to your SQL Server 2008. Install self-extracted folder and find the .msi file for C:\1033_enu_lp\x64\setup\masterdataservices.msi. Once you clicked on the file, follow the image tour below. You can ask me any questions in case you are still confused with any of the steps of the installation. While searching the internet for a similar installation process, I have landed on the official blog of MDS team where they have many interesting posts about it. If any concept written on my posts are contradictory to the information on the official blog, I suggest that you should follow the advice of official blog.

  • How to remove 'ApacheMonitor.exe' from notification area

    - by ekaj
    For some reason I had 2 instances of Apache running, and I have no idea how. I also had two instances of ApacheMonitor.exe showing in the "Notification Area Icons" place when you right click on your taskbar and go to properties. To fix the multiple instance issue, I deleted Apache completely and uninstalled the service (I did not use the .msi, I install from a .zip). Anyways, Everything from Apache is gone except the two things in the Notification Area Icon page. Does anyone know how to remove these two icons? I have completely uninstalled Apache, cleaned my registry with CCleaner, and rebooted. Does anyone have any other suggestions? Despite what the picture says, I do NOT have Apache installed, and it is not running.

  • Java Champion Jim Weaver on JavaFX

    - by Janice J. Heiss
    Hardly anyone knows more about JavaFX than Java Champion and Oracle’s JavaFX Evangelist, Jim Weaver, who will be leading two Hands on Labs on aspects of JavaFX at this year’s JavaOne: HOL11265 – “Playing to the Strengths of JavaFX and HTML5” (With Jeff Klamer - App Designer, Jeff Klamer Design) Wednesday, Oct 3, 3:00 PM - 5:00 PM - Hilton San Francisco - Franciscan A/B/C/D HOL3058 – “Custom JavaFX Controls” (With Gerrit Grunwald, Senior Software Engineer, Canoo Engineering AG; Bob Larsen, Consultant, Larsen Consulting; and Peter Vašenda, Software Engineer, Oracle) Tuesday, Oct 2, 12:30 PM - 2:30 PM - Hilton San Francisco - Franciscan A/B/C/D I caught up with Jim at JavaOne to ask him for a current snapshot of JavaFX. “In my opinion,” observed Weaver, “the most important thing happening with JavaFX is the ongoing improvement to rich-client Java application deployment. For example, JavaFX packaging tools now provide built-in support for self-contained application packages. A package may optionally contain the Java Runtime, and be distributed with a native installer (e.g., a DMG or EXE). This makes it easy for users to install JavaFX apps on their client machines, perhaps obtaining the apps from the Mac App Store, for example. Igor Nekrestyanov and Nancy Hildebrandt have written a comprehensive guide to JavaFX application deployment, the following section of which covers Self-Contained Application Packaging: http://docs.oracle.com/javafx/2/deployment/self-contained-packaging.htm#BCGIBBCI.“Igor also wrote a blog post titled, "7u10: JavaFX Packaging Tools Update," that covers improvements introduced so far in Java SE 7 update 10. Here's the URL to the blog post:https://blogs.oracle.com/talkingjavadeployment/entry/packaging_improvements_in_jdk_7”I asked about how the strengths of JavaFX and HTML5 interact and reinforce each other. “They interact and reinforce each other very well. I was about to be amazed at your insight in asking that question, but then recalled that one of my JavaOne sessions is a Hands-on Lab titled ‘Playing to the Strengths of JavaFX and HTML5.’ In that session, we'll cover the JavaFX and HTML5 WebView control, the strengths of each technology, and the various ways that Java and contents of the WebView can interact.”And what is he looking forward to at JavaOne? “I'm personally looking forward to some excellent sessions, and connecting with colleagues and friends that I haven't seen in a while!” Jim Weaver is another good reason to feel good about JavaOne.

  • Windows 7 "Backup completed but some files were skipped"

    - by Andrew Coleson
    I set up Windows 7 Pro to backup my files to a network path (woohoo!) and chose to backup "data for newly created users, libraries", and my user folder (no system image). All went fine (although the first backup took ~12 hours for some ridiculous reason), but at the end it gave me a message that "Your backup completed, but some files were skipped. Click to see which files." I checked and the "files" skipped were my 3 network-mapped drives, which is perfectly fine and reasonable behavior (I certainly don't need it to back up my network-mapped drives as part of my local PC backup), but in the Backup and Restore center it warns me that my Last backup was "Never" and the Action Center now has a permanent "Check your backup results" issue. Is there any way to set up the backup to exclude the network-mapped drives or tell it that I really don't mind that it skipped drives I never asked it to back up?

  • Runaway version store in tempdb

    - by DavidWimbush
    Today was really a new one. I got back from a week off and found our main production server's tempdb had gone from its usual 200MB to 36GB. Ironically I spent Friday at the most excellent SQLBits VI and one of the sessions I attended was Christian Bolton talking about tempdb issues - including runaway tempdb databases. How just-in-time was that?! I looked into the file growth history and it looks like the problem started when my index maintenance job was chosen as the deadlock victim. (Funny how they almost make it sound like you've won something.) That left tempdb pretty big but for some reason it grew several more times. And since I'd left the file growth at the default 10% (aaargh!) the worse it got the worse it got. The last regrowth event was 2.6GB. Good job I've got Instant Initialization on. Since the Disk Usage report showed it was 99% unallocated I went into the Shrink Files dialogue which helpfully informed me the data file was 250MB.  I'm afraid I've got a life (allegedly) so I restarted the SQL Server service and then immediately ran a script to make the initial size bigger and change the file growth to a number of MB. The script complained that the size was smaller than the current size. Within seconds! WTF? Now I had to find out what was using so much of it. By using the DMV sys.dm_db_file_space_usage I found the problem was in the version store, and using the DMV sys.dm_db_task_space_usage and the Top Transactions by Age report I found that the culprit was a 3rd party database where I had turned on read_committed_snapshot and then not bothered to monitor things properly. Just because something has always worked before doesn't mean it will work in every future case. This application had an implicit transaction that had been running for over 2 hours.

  • How to (hardware) RAID 10 on Ubuntu 10.04 LTS with 4 drives and motherboard with RAID contoller

    - by lollercoaster
    I have 4 500GB hard drives. I set up a RAID 10 in BIOS, much like shown here: http://www.supermicro.com/manuals/other/RAID_SATA_ESB2.pdf Then I followed these instructions: http://www.unrest.ca/Knowledge-Base/configuring-mdadm-raid10-for-ubuntu-910 Basically I cannot get it to work. I go through the instructions when I get to the "partition" section of the install, creating 4 RAID 1's (2 partitions on each drive, one for primary and one for swap space), then combining to make a RAID 10. Unfortunately it still shows 2 partitions, one 500 GB and another being 36GB for some reason. Any ideas? I think best would be if anyone had found good instructions (step by step) for how to do this...I've been googling for hours and haven't found anything...

  • DNS Settings in Cisco Wireless Lan Controllers

    - by Braden
    The WLC is a 2100 series and I have looked back and forth through the entire web interface. Originally the idea was that the gateway should be the DNS controler and the WLC pointed directly at the gateway. For some reason, random clients are having DNS specific issues when it comes to seeing certain shares around the network. The problems are also very intermittent. Aside from going to each box and implementing a static DNS is there ACTUALLY a DNS setting lodged into the WLC settings (and I am being a numpty and can't find them) or am I stuck with performing the config 1 by 1?

  • Hyper-V Manager: right-clicking on remote VM crashes MMC snap-in

  • Skype Optimization - Port Forwarding on a Router

    - by user19185
    I was watching this Video which talked about using port-forwarding to optimize your LAN for skype calls. According to the video, as explained in the first couple of minutes in the video, the reason you would need optimization is because if the person your call has a firewall setup, your connection has to go-through a third-party computer to connect to them. I believe I stated this correct (maybe not). None the less, my question is this: do both parties on the call need to enable port forwarding to optimize skype, or just one party (person)?

  • Windows 7 Recovery Console File Access Denied

    - by Ty Rozak
    Recently by computer crashed and was stuck in a boot loop. So I created a Windows Recovery CD and booted from that. When I use the command prompt in the recovery console, I cannot see any of my personal files or folders (such a my Users folder with My Documents). Is there a way to access these files? The only reason I would need to fix the computer properly would be to get these files off of the computer and onto a hard drive. Any other fix suggestions would be greatly appreciated. I have tried both system repair and system restore from the Recovery Console, but neither seem to work. Thanks.

  • SQL SERVER – Database in RESTORING State for Long Time

    - by Pinal Dave
    A very interesting question I received the other day. “Our database has been in restoring stage for a long time. We have already restored all the necessary files there. After restoring the files we are expecting that  the database will be in operational mode, however, it is continuously in the restoring mode. Any suggestion?” The question is very common. I sent user follow up emails to understand what is actually going on with the user. I realized after restoring their bak files and log files their database was in the restoring state because they had not restored the latest log file with RECOVERY options. As they had completed all the database restore sequence (bak and log in order), the real need for them was to recover the database from norecovery state. User can restore log files till the database is no recovery mode. If the database is recovered it will be in operation and it can continue database operation. If the database has another operations we cannot restore further log as the chain of the log file after the database is recovered is meaningless. This is the reason why the database has to be norecovery state when it is restored. There are three different ways to recover the database. 1) Recover the database manually with following command. RESTORE DATABASE database_name WITH RECOVERY 2) Recover the database with the last log file. RESTORE LOG database_name FROM backup_device WITH RECOVERY 3) Recover the database when bak is restored RESTORE DATABASE database_name FROM backup_device WITH RECOVERY To understand how the backup restores timeline works read Backup Timeline and Understanding of Database Restore Process in Full Recovery Model.

  • Is “Application Programming Interface” a bad name?

    - by Taylor Hawkes
    Application programming interface seems like a bad name for what it is. Is there a reason it was named such? I understand that people used to call them Advanced Programming Interfaces and then renamed to Application Programming Interface. Is that why it is poorly named? Why is it not named Application (to) Programmer Interface. I guess I'm just confused of the meaning behind that name? I write more about my confusion around the name here: BREAKING DOWN THE WORD “APPLICATION PROGRAMMING INTERFACE” This is a very confusing word. We mostly understand what the word Interface means, but “Application Programming”, what even is that. Honestly I'm confused. Is that suppose to be two words like “Application”, “Programming” and then the “Interface” is suppose to mean between the two? Like would a “Computer Human Interface” be an interface between a “Computer” and a “Human” (monitor , keyboard, mouse ) or is a “Computer Human” a real thing - perhaps the terminator. So a CHI is our boy Kyle Reese who is the only way we are able to work with the computer human. I think more likely “Application Programming Interface” was simply poorly named and doesn't really make sense. It was originally called an “Advanced Programming Interface” , but perhaps being a bit to ostentatious merged into the now wildly accepted “Application Programming Interface”. So now, not wanting to change an acronym has confused the living heck out everyone.... Any thoughts or clarification would be great, I'm giving a lecture on this topic in a month, so I would prefer not to BS my way through it.

  • List SQL Server Instances using the Registry

    - by BuckWoody
    I read this interesting article on using PowerShell and the registry, and thought I would modify his information a bit to list the SQL Server Instances on a box. The interesting thing about listing instances this was is that you can touch remote machines, find the instances when they are off and so on. Anyway, here’s the scriptlet I used to find the Instances on my system: $MachineName = '.' $reg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey('LocalMachine', $MachineName) $regKey= $reg.OpenSubKey("SOFTWARE\\Microsoft\\Microsoft SQL Server\\Instance Names\\SQL" ) $regkey.GetValueNames() You can read more of his article to find out the reason for the remote registry call and so forth – there are also security implications here for being able to read the registry. Script Disclaimer, for people who need to be told this sort of thing: Never trust any script, including those that you find here, until you understand exactly what it does and how it will act on your systems.

  • Windows Deployment Services

    - by timbrigham
    I have a slightly advanced Windows Deployment Services setup. My router hands out DHCP addresses, including the following config. ip dhcp pool Servers_100 network 192.168.100.0 255.255.255.0 bootfile boot\\x86\\pxelinux.0 next-server 192.168.100.50 default-router 192.168.100.1 dns-server 192.168.100.80 192.168.100.81 This works perfectly for other subnets - I have a couple screens in my pxelinux that allow me to select my various Linux installers or enter the windows preboot environment. For some reason I'm only receiving the default bootfile that opens to the windows preboot environment. Any idea why?

  • Network wide rule to forwared IP address

    - by Patrick
    Hi, we have a virtual machine which hosts a web based bug tracker in our network which is reached internally via e.g. 192.168.1.5:9800. From the outside we made a port forwarding in our firewall so that the web site can be reached via e.g. 72.10.10.10:9800. Now that works fine but the problem is that we got different IP addresses to reach the same service depending if we are in the office or at home and when the service sends out an email the link doesn't always work :) So we are looking for a solution to fix it. One could be to make a rule in out firewall that all communication to 72.10.10.10:9800 is forwarded to 192.168.1.5:9800... If that's possible that is considering it's an IP address + a port. The reason we used a port is because we only got one static public IP address but multiple virtual web appliances. Thanks for any suggestions or solutions :) Patrick PS: The network is a Win 2008 R2 domain by the way

  • Venezuela's Highly Inflationary Economy Means Changes to Financial Statements

    - by Theresa Hickman
    This is a bit of an esoteric topic, but given the number of U.S. Companies (particularly oil companies) that operate and have subsidiaries in Venezuela, I think it is worthy of an honorable mention. As you may or may not know, Venezuela's currency has had some changes over the years. In 2008, the Venezuelan Bolivar became the Bolivar Fuerte which dropped three zeros. So Bs.10,000 became Bs.F.10 and all their bills and coins were changed to reflect this. Then on Jan. 8, 2010, the government devalued the currency by 100%. The conversion from VEF to USD dropped from 2.15 to 4.30. (I always wanted to visit Venezuela; I guess it's time to book my vacation). The SEC recently labeled Venezuela a highly inflationary economy. This means that US companies with investments/subsidiaries in Venezuela will need to apply highly inflationary accounting rules starting on Jan. 1, 2010. In addition, companies need to make more detailed disclosures when the Venezuelan reported balances differ from the actual US dollar denominated balances. In a nut shell, if you formerly used translation, then starting Jan 1 of this year, you must now use remeasurement (or temporal method) to restate your Venezuelan entity's financial statements. See ASC topic 830, Foreign Currency Matters, which states that "[t]he financial statements of a foreign entity in a highly inflationary economy shall be remeasured as if the functional currency were the reporting currency." For you non-accountants that I haven't bored and are still reading at this point, the reason why the SEC is doing this is to ensure financial statements are presented as accurately as possible. Hyperinflationary economies have volatile currencies, such as Venezuela (it's not every day a currency devalues 100% overnight) which can distort financial statements if the local currency (Venezuelan Bolivar Fuerte) is used as the functional currency. To make financial statements more accurate, the reporting currency of the U.S. parent (US dollars) should be used as the functional currency. FASB.orgactually has a nice write-up on this.

  • Tunneling traffic through two VPN hops/tunnels.

    - by Roberto Sebestyen
    I am a web developer, and I find myself often working from home. But when I do, I am forced to Remote Desktop to the Office desktop computer and work from there. The reason is because the application I am working on needs to connect to servers at a Data Center via a VPN from the Office Desktop. HomeDesktop (Win7) --- PVN --- OfficeDesktop(WinXP) --- VPN --- Data Center What I would really like to do is, I would like to find a way to be using my Home desktop developing on that, and whenever my computer tries to access servers on the Data Center, I would like to tunnel that traffic through the two VPN tunnels separating me and the Data Center. I have admin privileges on both Office Desktop and Home Desktop, but I do not have any admin privileges in the Data Center. So what kind of tunneling solution could I use here? Is it even possible?

  • How to modify PATH variable for X11 during log-in?

    - by user1028435
    Original question is here: Overwriting "Print Screen" actions in linux without administrative rights. Decided to revise my question, based on what I learned there: Essentially, my problem is that I am working on some lab computers (read: no administrative rights) that, if I log in, I need to change the PATH variable as X11 starts. The reason is that I need to change the PATH variable at this time, as opposed to later, is that the Print Screen command seems to "bind" during login (forgive my bad explanation of this). You can see in the work-around I listed in the previous section, that I can make it work by starting a new X, but I was wondering if it is possible to change upon login. Any ideas?
