• Unable to mount location ubuntu 12.10

• Now that Apple's intending to deprecate Java on OS X, what language should I focus on?

  - by Smalltown2000

  After getting shot down on SO, I'll try this here: I'm sure you'll all know of Apple's recent announcement to deprecate Java on OS X (such as discussed here). I've recently come back to programming in the last year or so since I originally learnt on ye olde BASIC many years ago. I have a Mac at home and a PC at work and whilst I have got Windows and Ubuntu installed on my Mac as VMs, I chose to focus my "relearning" on VB first (as it was closest to BASIC) and then rapidly moved to Java as it was cross platform (with minimal effort) and so it was easiest to work on code from both OSes. So my question, if the winds of change on Mac are blowing away from Java and in this post-Sun era, what would be the best language to focus my new efforts on? Please note, this isn't a general "which language is better?" thread and or an opportunity for the associated flame-war. There's plenty of those and it's not the point. I realise that in the long term one shouldn't be allegiant to an individual language so, taking this as an excuse, the question is specifically which is going to be the most quick to be productive on given the background whilst bearing in mind minimum portability rewrites (aspiration rather then requirement) and with a long term value of usage. To that I see the main options as: C# - Closest in "style" to Java but M$ dependent (unless you consider Mono of course) C++ - Hugely complex but if even slightly conquered, then a win? Is it worth the climb up the learning curve? VB.Net - Already have background so easiest to go back to but who uses VB for .Net these days? Surely if using a CLI language I should use C#... Python - Cross-platform but what about UI for the end-user? EDIT: As a usage priority, I envision desktop application programming. Though the ability to branch in the future is always desirable. I guess graphics are the next direction once basics are in place.

• How do I map a friendly name (e.g. www.example.com) to 127.0.0.1:port# on Mac OS X

  - by Fred Finkle

  I am trying to create a demo for a class of mine and I want to configure "fake" domain names on my laptop. A previous question "Can I specify a port in an entry in my /etc/hosts on OS X?" contained an answer indicating that to do it you must use /etc/hosts plus changes to the iptables "If OS X uses iptables you could point xyz.com to some ip in the hosts file like 157.166.226.25 and then: sudo iptables -t nat -A OUTPUT -p tcp --dport 80 -d 157.166.226.25 -j DNAT --to-destination 127.0.0.1:3000 " Since OS X doesn't use iptables, how do I do the equivalent using the tools available on OS X? (the original "asker" seemed to know how to do this, so it wasn't explained). Thanks in advance.

• Zentyal Server : Setting up secure VPN Client

  - by JustShrey

  I have officially exhausted pretty much all my google-fu trying to set this up so I'm asking my question here. For the record, I am a mid level rookie who has played around with servers in his spare time but have never worked with Zentyal Server. Now, I have been able to set up the server as a gateway, with one Network card being external and the other facing the internal Network. The Internal network computers are able to access the internet without any issues. What I need to do is to setup a open-vpn client on the central server so that all Internet data goes though the secure VPN session. As far as I can see, I can't set up the vpn session through the web admin page. Could somebody point me in the right direction? How would I go about doing this? Regards Shreyas

• Black spray (?) on a laptop's heat sink assembly

  - by arnehehe

  We have a HP Pavilion DV3 4000SB that was given an error on startup that the fan was having problems (System Fan 90b error message) So I decided to open the laptop up and clean the fan, as that seemed the easiest option. Upon opening it up, at first I froze and thought "No wonder! The whole thing's burnt!", but then I started thinking it looked more like someone used a spraycan on it. I looked up a video on youtube of someone disassembling his Pavilion and noticed there wasn't any of the black on his, so my question here is: Have any of you encountered this, or know what it is? Or if it's something that could point to a problem?

• is using Hosts for resolving a sql-server more performant?

  - by Ice

  Hi, we have a legacy application which uses a access.mdb with hundreds of ODBC-connected tables on a sql-server. the access.mdb contains nothing else than these odbc-connections. Now we consider to use a virtual sql-servername for these odbc connections and resolve it in the local hosts-file with the ip-address of the real sql-server. Like this we can easy switch between a test-sql-database server and the the server for production in changing one single entry in the hosts. EVERYTHING works fine and now comes the question: Could it be that this is more performant because there is one single point on resolving the sql-server (name or ip-address)? Is there something like a network-cache / DNS-Cache? peace Ice

• Help: My SSL Certificate expired but I can't renew this weekend, is there a way I can disable SSL through IIS?

  - by shogun

  Or perhaps force redirect to HTTP when they request HTTPS? I tried removing the SSL port settings under 'Advanced' but it broke the login page. I don't want to do a deploy/recompile right now but I am able to edit the VIEWS. However I am thinking there may be a way for IIS to do this, but then again I think the .NET code tries to force SSL. Crap. This is bull crap because I was bugging people about getting the new certificate since December and they were like oh we will take care of it... I think it may have even gotten to the point where they were getting annoyed with me hassling them about it! (rant over.) And yes, the key is that more support tickets will be caused by the browser giving a security error than if SSL was removed entirely for one day. Becaues they wouldn't very very likely not notice it being gone.

• Setting a mapped drive in Virtual hosts causes apache to not start

  - by darksoulsong

  I´m trying to set a virtual host on my windows 7 machine. The folder I want to point to is located on a centOS machine and the folder path is Z:\Websites\Online\MyClient\Site. But something strange happens when I set the document root like this: DocumentRoot "Z:\Websites\Online\MyClient\Site" Apache do not restarts after that. When I take a look at the log, there is an error pointing to that line, where I added the path to the folder: Syntax error on line 48 of C:/Program Files/Zend/Apache2/conf/extra/httpd-vhosts.conf: DocumentRoot must be a directory. There must be a way to make it work like this, by setting an Apache Installation on a machine and pointing it to a folder located on another computer, right? My hosts file is set like this: 172.17.10.1\Data\Websites\Online\MyClient\Site MyClient.local ANY HELP would be VERY appreciated.

• Distribution upgrade freezes

  - by lugte098

  When upgrading from Ubuntu 10.04 to 10.10 the distribution upgrade program freezes after it notifies me of a change in /etc/apparmor.d/usr.bin.mysqld and asks me to keep the old file or accept the new changes (I accepted them). The terminal says: Configuration file `/etc/apparmor.d/usr.sbin.mysqld' ==> Modified (by you or by a script) since installation. ==> Package distributor has shipped an updated version. What would you like to do about it ? Your options are: Y or I : install the package maintainer's version N or O : keep your currently-installed version D : show the differences between the versions Z : start a shell to examine the situation The default action is to keep your current version. *** usr.sbin.mysqld (Y/I/N/O/D/Z) [default=N] ? y Installing new version of config file /etc/apparmor.d/usr.sbin.mysqld ... The program hasn't done anything after this for about 2 hours now and I have no idea what I should do at this point. Can I quit the program and restart it? Or is there another action I should take? It did however change the '/etc/apparmor.d/usr.sbin.mysqld' to the new version, but is still frozen...

• Why does my system slow down or freeze when there is heavy disk activity?

  - by user72270

  Im a first-time user to Ubuntu-12.04 with WUBI installation. My NoteBook Information : Dell vostro 3450 : i5 2410m, 3 gb ram, intel hd3000, amd 6630m hybrid. Surfing and playing games works flawlessly, however, I'm having huge problems when installing applications and generally copying and moving files. When doing so, system is significantly slower and freezes quite often (Firefox gets bluish, sometimes even black n white). I would say that Ubuntu allocates too much resources on file transfers and installing, but even these tasks are very slow. Here is very specific example : today, i tried to move 6 GB file from win 7 installation. It was good at first, i jumped to firefox but after a while firefox started to randomly turn bluish and mouse was randomly stopping working. It was gradually worse and worse and it got to a point when firefox black n whited and mouse wasn't working at all. I raged and went for some meal, when i got back screen was black. It probably unlogged me due to inactivity, when i pushed random button to bring screen to life i had to wait few minutes to let it show me only my screen background. No log in screen, just background and working mouse. NoteBook fan was working at 100 % so I assumed that file transfer was going on and I left it to work. Nothing then changed for a full hour so I hard rebooted it. File transfer unsuccessful, It transfered hardly 2 gigs. Is this normal ? What to do in these situations ? It didn't let me load system manager and not even terminal. Thanks.

• Setting up central git repo on local Mac network

  - by Dashman

  We are a team of three, all working on our local machines on the same internal network. We will all be working on websites in local working copies of the same Git repo hosted on Github. We have an internal staging machine here (dev.internal), and I am looking for a way for us to be able to push to this machine. At each milestone in the development cycle. In essence, all I really want us to be able to do is add the dev.internal machine as a remote, and push to this whenever we are ready. Could somebody please point me in the right direction to get this set up?

• How can we recover/restore lost/overwritten data in our MSSQL 2008 table?

  - by TeTe

  I am in serious trouble and I am seeking professional advices here. We are using MSSQL server 2008. We removed primary key, replaced exiting data with new data resulted losing our critical business data in its child tables on MSSQL Server. It was completely human mistake and we didn't have disk failure. 1) The last backup file was a month ago which means it is useless. 2) We created Maintenance Plans to backup our database at 12AM everyday but those files are nohwere to be found 3) A friend of mine said we can recover from Transaction Logs. When I go to TaskRestore Transaction log is dimmed/disabled. 4) I checked ManagementMaintenance Plans. I can't find any restored point there. It seems that our maintenance plan hasn't been working. Is there any third party tool to recover lost/overwritten data from MSSQL table? Thanks a lot.

• Why doesn't wireless work on Wubi 12.04 with a Broadcom BCM4312 card?

  - by Kristin

  I have recently set up ubuntu 12.04 on my laptop using the Wubi installer. I am having a very difficult time setting up a wireless internet connection. I am currently set up with an ethernet connection which I have used to download all new updates and to activate the Broadcom STA wireless driver. I have tried several things in the terminal based on other people's posts: ~$ rfkill list 0: brcmwl-0: Wireless LAN Soft blocked: no Hard blocked: yes ~$ rfkill unblock all It doesn't change anything. I also tried rebooting and connecting to the internet on my Windows Vista OS, and it worked, so I know that the connection should not be hard blocked. I have also tried installing b43 firmware (lp/phy version) that is supposed to work with my chip (BCM4312). It seems to have no effect. Then I tried: ~$ iwconfig lo no wireless extensions. eth1 IEEE 802.11 Access Point: Not-Associated Link Quality:5 Signal level:0 Noise level:0 Rx invalid nwid:0 invalid crypt:0 invalid misc:0 eth0 no wireless extensions. This is my first time trying to work with ubuntu, so I would appreciate any help. Thanks. Also sorry this is poorly formatted. I'm having troubles with that too.

• Have main website hosted on 3rd party while keeping Google Sites for Users

  - by vinnybozz

  Hi, I want a third party hosting my main site with PHP, MySQL, etc... I don't know which DNS records to modify. Is it possible to have the following mappings: www.example.com = 3rd party hosting blog.example.com = other 3rd party hosting mail.example.com = Google Mail docs.example.com = Google Docs sites.example.com = Google Sites sites.example.com/internal-site = Google Sites internal site ... Right now in TotalDNS, I have www = ghs.google.com. If I modify only this record to point to the IP provided by the 3rd party hosting, is it going to work ? Do I also need to add NameServers, remove the ones Google added ? Thx for the help

• Using the RadTransitionControl in Task-It

  Download Source Code NOTE: To run the source code provided your will need to update to the RC (release candidate) versions of Silverlight 4 and VisualStudio 2010.  In a recent Ask the Experts webinar I showed a simple solution that had similarities to one that I had used in my recent MVVM post, but had a few extra twists on it. I have since been asked if I could post the source code for this demo, so here it is (I am using similar techniques in my Task-It application). The database Before running the code for this app you will need to create the database. First, create a database called MVVMProject in SQL Server, then run MVVMProject.sql in the MVVMProjectDemo/Database directory of your downloaded .zip file. This should give you a Task table with 3 records in it. You will also need to update the connection string in web.config to point to your database ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• More Win 8 Education is Needed

  - by D'Arcy Lussier

  “My mail doesn’t work”. That’s what a colleague running Windows 8 said to me the day after he installed Windows 8 on his work laptop. “When I click my email, nothing comes up.” I took a look and realized what was going on – he was clicking the Windows 8 UI Mail app and assumed that this was somehow connected to his Outlook which was installed as a desktop app. And so highlights a major educational challenge that Windows 8 will encounter – millions of users used to one style of interface now being introduced to a new one that runs side-by-side with their desktop. At work we had an internal tech user group meeting, and we were showing new features of VS.NET 2012 and Windows 8. When we started talking about the difference between Windows 8 UI Apps (AKA Windows Store Apps), people started asking some good questions: - Can we share a codebase between desktop and Windows Store Apps? - What’s the difference between WinRT and .NET? - Why would we create a Windows Store App and not just a Desktop app? Of course, people are looking at this from a traditional desktop point of view and not a tablet platform, which is really the market that Windows Store Apps will shine on. Still, for developers who not only need to educate themselves but also educate their clients, we’re going to need a better understanding of Windows 8 to see it get real traction within the business/enterprise market.

• Clean Install Windows on a Acer Aspire Laptop with a Hybrid Drive

  - by user1325179

  I'd like to do a clean install of Windows 8 on my Acer Aspire laptop (Aspire M5-481PT) with a hybrid drive. Physically, there seem to be two hard drives (an HDD and an SSD). So when I try to clean install Windows, I am asked to pick a drive. The HDD has five partitions (some seem to be recovery related), and the SSD has two partitions. Which partitions should I delete (if any), and onto which drive should I install Windows 8? And then how can I instruct Windows 8 to use the HDD-SSD combination as a hybrid drive? Edit: Currently, the operating system seems to be installed (from the factory) on the HDD. The SSD is invisible in File Explorer. It is only visible in disk utilities. I'm betting I need to install Windows to the HDD, and then point Windows to use the SSD for the hybrid relationship. Also, the SSD is about 20 GB. The HDD is about 450 GB.

• Ubuntu automatic logout whenever I execute exe files

  - by KeepTrying

  I have a problem. Here's the thing. There were 4 partitions in my hard drive: One for ubuntu root folder One for ubuntu home folder One for general stuffs like music, movies... And the last one for SWAP To install Windows 7, I resized partitions and moving the order of partitions by using GParted. I moved all of the ext formatted partitions to the left, so that means the spare space would be at the right. And I formatted that spare space in NTFS and install windows 7. After successfully installing windows 7, I used LiveUSB to fix grub. I installed Boot Repair and, with just one click, now I can dual boot ubuntu and windows 7. But, the point, because of changing the order of partitions, especially the partition consisting of home folder, I couldn't log in the ubuntu. I used recovery mode and changed file /etc/passwd. Everything almost got back to normal except one thing. The windows apps that I installed via wine don't work anymore. I run them via accessing menu Applications/Wine/Programs but nothing loads. One more thing, when I double click on exe files to run them, ubuntu suddenly log outs. Thank you for reading my post, it's quite long and my English is fairly poor. I'd appreciate for anyone who reads it.

• Uptime concerns in case of AWS outage

  - by Aditya Patawari

  I am running an Elastic Load Balancer backup by 2 instances in different Availability Zones in US East. I am using Multi-AZ RDS as well. Ideally this should ensure that if one AZ goes down, it should not effect the app because everything is spread across multiple AZs. But the recent AWS outage took the app down for a long time. I am not sure how this can happen. It would be great if someone can point out what went wrong. Major question here I have is how can I avoid this in future? I can setup app servers across different regions or even providers and use DNS for load balancing but what do I do with MySQL? Read Replicas will introduce some lag which I would want to avoid.

• Share iTunes Library from Nas across several clients. How in Windows

  - by Mych

  I found this article http://gigaom.com/apple/one-itunes-library-on-multiple-computers/ which describes sharing a single library with multiple clients. Unfortunately this article is for Macs and I use Windows. The article mentions 3 jobs that need to be completed.' A) - pointing all clients to the location of the Library. This is understandable and I can replicate using windows clients. B) Universal Library Set-up. This mentions holing the option key and double click iTunes icon. This is so you can create the index at a specific location C) Point clients to index. Again this mentions Option double click. What is the Windows equivalent to option double click iTunes?

• Proxy between data centers [closed]

  Possible Duplicate: Can IIS be configure to forward request to another web server? We are switching data centers (actually datac-center to EC2 to be specific) and some customers have not yet made DNS changes to point the domains to the new load balancers. We are thinking of leaving the existing servers up and just using a proxy server to forward the request to the new load balancer. Can anyone recommend a good proxy server for doing this I've got squid installed but it seems it's fairly easy to just have a fairly wide open proxy server and we don't want this.

• How to retrieve connection details of CheckPoint SSL Network Extender?

  - by amoe

  My workplace uses a Java-based VPN tool named CheckPoint SSL Network Extender. I would like to configure the VPN connection myself using stock OS tools, because I find the applet to be rather unstable. How would I go about getting all of the connection details needed to manually connect to the VPN? My workplace only supports the official client. When I am connected with the Java applet, if I run ipconfig /all I can see that a hidden network connection is created named Check Point Virtual Network Adapter For SSL Network Extender - Packet Scheduler Miniport. I can see the various IP and DNS details there as well. However, because I need to log in to the applet-based tool, I presume I need to export some kind of key in order to use OS tools to configure this. Is this even possible? Answers for any OS are great although I am using Windows XP to test, and also want to use Linux clients.
