• Only one user at once through remote

  - by Lazlo

  Hi, This is probably an easy question for anyone used to servers, and I know I once managed to do it, but I don't remember how. I purchased a VPS and am able to connect correctly as Administrator, and can start, let's say, MyServer.exe. Problem is, if I connect as Administrator on another device, this process is still there, but I can't see it. What I want to do is limit the connection per user to 1, and disconnect others when one logs in. I know there was a simpler term, a simple way, but I truly don't remember. And since I'm not used to the vocabulary of servers, I couldn't find it in the S/F questions. Thanks in advance!

• Is it possible to use a laptop charger in other laptop with different specifications?

  - by poz2k4444

  Let's say I have my laptop charger that uses 19.5V and 3.9A and I want to use it in other laptop that has no charger but it needs just 19V and 3.16A, I've studied a little of electtronics and I know that the amperage doesn't affect because the computer will use just the necessary, but I'm not really sure about the voltage. I read this post and I know the polarity is the same and the connector fits, but it doesn't say anything about voltage, I also know if the voltage of the charger were lower than the specification it'll not be a problem, but what about this little almost insignificant difference??

• Windows 8 won't boot after Boot Repair

  - by Rudolph Gottesheim

  I've got a Sony Vaio laptop. Until yesterday I had Windows 7 and Ubuntu 12.04 installed. Today I upgraded to Windows 8, which killed my OS selection screen. So I booted to Ubuntu 12.10 from a USB stick and ran Boot Repair. This recovered the GRUB screen and let me boot into my Ubuntu 12.04 installation, but now I can' boot Windows 8. When I select the option that booted Windows 7 before, it looks like it wants to start Windows 7 (sic) again (black screen, with the text "Windows is loading" or something), but then reboots the machine after a few seconds. I'm sure Boot Repair can fix this, but I know far too little about the whole booting thing to know the right settings for it. Here's my boot repair report thing.

• allow SSH to bypass VPN on OSX mavericks, openvpn, pf

  - by zycho42

  My home computer connects to the internet through an OpenVPN connection. However, I would like to be able to connect to my home computer from outside over ssh. Ssh is set up and working, but when I connect to the vpn ssh is only accessible from inside my home network. I figure what's going wrong is my router forwards incoming ssh connections to my mac, but then my mac replies over the vpn, so the connection from outside times out. I've got pf set up for a couple of other things, but I can't figure out how to let the ssh replies bypass the vpn using pf. I've come across other solutions that use ip tables, routing tables and rules, but I can't figure out how to set that up on mavericks. I've been searching for this for a while now but I haven't found a working solution. Any help would be greatly appreciated!

• Windows 7 Connection Sharing unable to access some sites

  - by Kristopher Ives

  I have a pretty sad networking situation that involves connecting to an open Wireless network and sharing that connection to an Ethernet that is plugged into a Linksys router. This has been done with XP and Windows 7, and it works great with XP. The problem with Windows 7 is that only some DNS will work. I don't know if it's been poisoned on the network above us (which we have no control over), but we've tried clearing the DNS cache as well as moving to using Google's DNS servers (8.8.8.8, 8.8.4.4). Here is a really quick list of sites that won't respond to DNS requests at all via dig, although if I get the IP address I can ping them: facebook.com yuilibrary.com twitter.com A lot of sites do work though. Anyone have an idea? It may be a subnet problem? If anyone wants more info let me know.

• Merging Two KML Files to Display Them with Different Marker Icons on Google Maps

  - by Maxim Z.

  Let's say that I have two spreadsheets with addresses. I uploaded these spreadsheets into Google Fusion Tables, geocoded the addresses, and exported the results as KML files. Now, I want to take these two KML files and merge them, while maintaining the location data and using it to map the points with Google Maps. Well, I found a way to easily merge the KML files: import both of them into a "My Maps" map with Google Maps! However, my problem is this: when I do that, all of the locations in my data have the same marker icon on the map. From past experience, I know that these markers can be somehow defined inside the KML files. Is it possible to combine these two KML files while giving one's points one marker icon and the other's points another marker icon? Just in case my question is confusing, what I mean, is giving the first set of points blue markers, for example, and the other set of points red markers, so that they can be overlayed.

• Important Tips to make a user friendly Homepage

  - by Aditi

  We have done a lot of redesign work lately for many online businesses.. There are some basic things we want to stress into any web design which make it usable! Unfortunately most designers care about the graphic elements, clean code & navigation only. Most designers do not realize that a design they did could be a masterpiece to them but for a layman it could be tough to use. It is so very important to understand usability & call to action for any business and then implemented on their website Homepage. Showcase Offering The sole purpose of their websites needs to be mentioned on the homepage, what they are offering, why should one do business with them and why they are better than other competitors. Include a tag line under your logo that explicitly summarizes what the site or company does. Ease of Navigation Make it easier for your user to find what they are looking for, some archives, articles, services etc. A visible and easy to use Navigation allows just that. You may also want to feature some of the most visited content on the homepage itself. Search Form Let your users take advantage of a search form from your homepage, keep it visible enough so if they have trouble locating certain content using your navigation. The Search Bar will come handy in such situation. Especially if you have thousands and thousands of web pages. Liquid Layout There was a time when people used standard resolution, not any more. People have different screen sizes and most people now browse on handhelds. Try keeping liquid width so people can adjust as per their choice. First impression is last impression, leaving one through your perfect homepage can do wonders for your business.

• The power of explicit social networks

  - by me

  Last week I had the pleasure to write a guest post on the Oracle WebCenter blog  with the topic The Power of Social Recommendations where I described Implicit and Explicit Social Recommendations models and how they relate to a Social Engagement Strategy. Now let's look at a real live example. Apple has implemented an explicit Social Network model with So what ? Users do this already on Facebook and Twitter!  (see ZDNet blog post : Ping: Apple should leave social to Facebook, Twitter) BUT there are some major  advantages: "100 % control over the explicit Social Network ->  direct customer relationship without a social intermediary like Facebook or Twitter Total  access to the Social Graph ->  own the Social Graph data from their users and no need to "buy" it from external social network providers Integrated into the core business model ->  harvest all Social Graph data  to provide  highly personalized and trusted recommendations Isn't this the dream of any company which thinks about their social media strategy?  and guess what - Oracle Social Network is all about this - building explicit Social Networks with seamless integration into  your core business processes and applications follow me on twitter:  http://twitter.com/peterreiser Enterprise2.0, enterprise2.0, social networks, social media, apple

• BizTalk: mapping with Xslt

  - by Leonid Ganeline

  BizTalk Map Editor (Mapper) is a good editor, especially in the last 2010 version of the BizTalk. But still sometimes it cannot do the tasks easily. It is time for the Xslt code, It is time to remember that the maps are executed by the Xslt engine.  Right-click the Mapper Grid (a field between the source and target schemas) and choose Properties /Custom XSLT Path.  Input here a name of the file with Xslt code. Only this code will be executed, forget the picture in the Mapper, all those links and functoids.  Let’s see the real-life example. There are two source Addresses. One is on the top level and the second is inside the Member_Address record with MaxOccurs=* . The target address is placed inside the Locator record with MaxOccurs=*. The requirement is to map all source address to the one target address structure. The source Xml document looks like: The result Xml should be like this: Try to do this mapping with the Mapper and you will spent good amount of time and the result map would be tricky. If we use the Xslt code, the mapping will be simple and unambiguous, like this: Simple, elegant.

• Conflict between variable substitution and CJK characters in BASH

  - by AndreasT

  I encountered a problem with variable substitution in the BASH shell. Say you define a variable a. Then the command $> echo ${a//[0-4]/} prints its value with all the numbers ranged between 0 and 4 removed: $> a="Hello1265-3World" $> echo ${a//[0-4]/} Hello65-World This seems to work just fine, but let's take a look at the next example: $> b="?1265-3?" $> echo ${b//[0-4]/} ?1265-3? Substitution did not take place: I assume that is because b contains CJK characters. This issue extends to all cases in which square brackets are involved. Surprisingly enough, variable substitution without square brackets works fine in both cases: $> a="Hello1265-3World" $> echo ${a//2/} Hello165-3World $> b="?1265-3?" $> echo ${b//2/} ?165-3? Is it a bug or am I missing something? I use Lubuntu 12.04, terminal is lxterminal and echo $BASH_VERSION returns 4.2.24(1)-release. EDIT: Andrew Johnson in his comment stated that with gnome-terminal 4.2.37(1)-release the command works fine. I wonder whether it is a problem of lxterminal or of its specific 4.2.24(1)-release version.

• Can't move or access WSS Central Administration site

  - by Jim

  We have several WSS Servers: WSS1 WSS2 WSS3 WSS4 SharePoint thinks that Central Administration is on WSS3 and that it can be access via SSL on port 22641. The problem is that central administration is not there. It was removed using the config wizard. We removed central admin from all servers to clean everything out, and we tried installing Central Admin on WSS1. The alternate access mappings still point to central admin on WSS3. We tried deleting the alternate access mappings, but SharePoint won't let you delete central admin's mapping. Later, we removed central admin from all of our servers and tried creating the Central Admin website on WSS3, where SharePoint already thinks it is. But for some reason SharePoint is creating the alternate access mappings using SSL, and we don't have a certificate for the server. Why is SharePoint creating alternate access mappings routing an https internal URL by default? How can we move central administration to a new server? We are using WSS 3.0.

• Keyboard locking up in Visual Studio 2010, Part 2

  - by Jim Wang

  Last week I posted about looking into the keyboard locking up issue in Visual Studio.  So far it looks like not a lot of people have replied to provide concrete repro steps, which confirms my suspicion that this is somewhat of a random issue. So at this point, I have a couple of choices.  I can either wait for somebody in the community to provide a repro of the problem that I can reliably run into, or I can do the work myself. I’m going to do both, so while I’m waiting for more possible bug reports, I’m going to write a tool that models the behavior of a typical Visual Studio user and use that to hopefully isolate the problem. I’ve chosen to go with this path since given the information in the bug reports, it seems people hit the issue with many different configurations in many different scenarios.  This means that me sitting down without any solid repro steps is likely not going to be a good use of time.  Instead, I’m going to go with a model-based testing approach where I will define a series of actions that a user in VS can do, and then proceed to run my model.  I’ll let you guys know how this works out for isolating bugs :) I’m using an internal tool for the model engine and AutoIt for the UI automation (I want something lightweight for a one-off).  One of the challenges will be getting feedback: AutoIt is great at driving, but not so great at understanding what success and failure means.

• Windows Color Calibrator Does Not Retain Color Settings

  - by Zian Choy

  When I try to calibrate the monitor using Windows 7's color calibrator, the monitor rejects changes to the color settings. For example, one of my monitors has a blueish tinge. If I click my mouse to tone down the blue and then let go of my mouse the monitor will go back to being blueish. At the moment, I am getting around the problem by using the color controls in the monitor's on screen displays. How can I get the color calibrator to work? Update: I tried checking the color settings in the ATI Radeon Catalyst Control Center and noticed that I can't do anything. The "Reactivate ATI color controls" button keeps flashing and any changes I try to make are discarded instantly.

• How to Run Pam Face Authentication

  - by Supriyo Banerjee

  I am using Ubuntu 11.10. I went to the following URL to download the software 'Pam Face Authentication': http://ppa.launchpad.net/antonio.chiurazzi/ppa/ubuntu/pool/main/p/pam-face-authentication/ and downloaded the version for natty narhwall. I installed the software using the following commands: sudo apt-get install build-essential cmake qt4-qmake libx11-dev libcv-dev libcvaux-dev libhighgui2.1 libhighgui-dev libqt4-dev libpam0g-dev checkinstall cd /tmp && wget http://pam-face-authentication.googlecode.com /files/pam-face-authentication-0.3.tar.gz sudo add-apt-repository ppa:antonio.chiurazzi sudo apt-get update sudo apt-get install pam-face-authentication cat << EOF | sudo tee /usr/share/pam-configs/face_authentication /dev/null Name: face_authentication profile Default: yes Priority: 900 Auth-Type: Primary Auth: [success=end default=ignore] pam_face_authentication.so enableX EOF sudo pam-auth-update --package face_authentication The software installed and I can run the qt-facetrainer. But the problem is when I restarted my system, I saw that the default login screen is appearing where I should put my password to login. The webcam is not starting at all. And I cannot login with my face. Which means I think that pam face authentication programme is not starting at all. Please let me know how I can login with my face using pam face authentication programme.

• Does my motherboard support dual-core processors?

  - by Filip

  Hi there! I'm very confused about my motherboard (ConRoe945PL-GLAN) It's manual says, that i can use only some kind of ConRoe processors. But some pages on internet says that i can plug in almost everything. For ex.: aria.co.uk says that i can plug in even Core 2 Duo. It would be awesome if i would not have to buy new motherboard! Anyway, if my motherboard will not let me to plug in Core 2 Duo, should i buy Pentium 4 (very cheap) with 3,2 GHz and insanely overclock it to have some performance or buy new motherboard + new processor for big money? THX for any answers! =)

• Using Komodo IDE as Text editor from the OS X terminal

  - by lexu

  According to this URL I should be able to start Komodo IDE from the command line when I want to edit a file. I set up the symbolic link using (on single line) ln -sf "/Applications/Komodo IDE.app/Contents/MacOS/komodo" /Users/lexu/bin/komodo but when I type afg-2:~ lexu$ komodo .bash_profile I get dyld: Library not loaded: /usr/lib/libsqlite3.dylib Referenced from: /System/Library/Frameworks/Security.framework/Versions/A/Security Reason: Incompatible library version: Security requires version 9.0.0 or later, but libsqlite3.dylib provides version 1.0.0 /Applications/Komodo IDE.app/Contents/MacOS/run-mozilla.sh: line 131: 4370 Trace/BPT trap "$prog" ${1+"$@"} and a dialog that says My guess is I need to somehow let Komodo know it needs to use different libraries?

• Is there a way to launch a command within a proper zsh shell ?

  - by Wam

  I'm not really clear with my question here, let me rephrase it : I've setup a launch_workspace.sh to launch directly tmux with 5 different commands loaded. Here is my current content : #!/bin/sh tmux new-session -d -s scube -n 'vim' "vim" tmux new-window -t scube:2 -n 'server' "$SHELL -c 'script/rails server'" tmux new-window -t scube:3 -n 'yard' "$SHELL -c 'bundle exec yard server --gems'" tmux new-window -t scube:4 -n 'spork' "$SHELL -c 'bundle exec guard'" tmux new-window -t scube:5 -n 'autotest' "$SHELL -c 'bundle exec autotest'" tmux new-window -t scube:5 -n 'shell' "$SHELL" tmux select-window -t scube:1 tmux -2 attach-session -t scube Problem is : my zsh ($SHELL beeing zsh) launches said commands, but when I Ctrl+C any of these, it closes the full zsh (hence my tmux window) and not just return to a proper zsh prompt. Is there a way to have said behavior, to launch zsh with a command and return to a zsh prompt when the command fails ? Cheers

• Apache: Virtual Host and .htacess for URL Rewriting not working

  - by parth

  I have configured a virtual host in my local machine and every thing is working fine. Now I want to use SEO friendly urls. To achieve this I have used the .htaccess file. My virtual host configuration is: <VirtualHost *:80> DocumentRoot "C:/xampp/htdocs/ypp" ServerName ypp.com ServerAlias www.ypp.com ##ErrorLog "logs/dummy-host2.localhost-error.log" ##CustomLog "logs/dummy-host2.localhost-access.log" combined </VirtualHost> and my .htaccess file has: AllowOverride All RewriteEngine On RewriteBase /ypp/ RewriteRule ^/browse$ /browse.php RewriteRule ^/browse/([a-z]+)$ /browse.php?cat=$1 RewriteRule ^/browse/([a-z]+)/([a-z]+)$ /browse.php?cat=$1&subcat=$2 The above .htaccess setting is not working. After that I modified my virtual host setting and it is working. The new virtual host setting is: <VirtualHost *:80> RewriteEngine On RewriteRule ^/browse$ /browse.php RewriteRule ^/browse/([a-z]+)$ /browse.php?cat=$1 RewriteRule ^/browse/([a-z]+)/([a-z]+)$ /browse.php?cat=$1&subcat=$2 ServerAdmin [email protected] DocumentRoot "C:/xampp/htdocs/ypp" ServerName ypp.com ServerAlias www.ypp.com ##ErrorLog "logs/dummy-host2.localhost-error.log" ##CustomLog "logs/dummy-host2.localhost-access.log" combined <Directory "C:/xampp/htdocs/ypp"> AllowOverride All </Directory> </VirtualHost> Please let me know where I am going wrong in the .htacess file for url rewriting. I do not want to use the settings in virtual host, since for every change I have restart apache.

• Selling Android apps from Latvia? or should I just put banners?

  - by Roger Travis

  I am in Latvia ( which is not supported to sell apps at android market ), so I am thinking about the best way of monetizing my app. So far I've come up with such options: somehow imitate that I am from a supported country, get a bank account there, etc. use PayPal for in-app purchases. The player get, say, first 10 levels for free, but then is asked to pay 0.99$ for the rest of the game. downsides: player might not feel comfortable entering his paypal details into an app. also android market might not really like that. making the app free and get money from advertising... let's do some calculation here, say, I get 1m free downloads, each user during his playtime would see 10 banners, therefor 10m / 1000 * 0.3 = gives roughly 33k$ ( if we use adMob with their 0.3$ per 1000 impressions ). On the other hand, if we use paypal in app purchase, we need a 3% or more conversion rate to beat this... hmm... What do you think about all this? Thanks! edit: from what I just read all over the net, it looks like advertisers will change their eCPM price a lot without you understanding why... while using in-app paypal purchase you can at least somehow monitor the cashflow.

• Mac OS X: easiest (free, non-QuickTime Pro) application for converting numbered folder of images to

  - by Jared Updike

  I'd like to convert a folder of PNGs into a quicktime .mov with PNG compression (it's a folder of fractals in an animation; PNG compression works great here and the losslessness is important). What programs will do this with minimal fuss? (I don't have or want to pay for a full license of QuickTime Pro.) UPDATE: Let me make this more clear: minimal fuss means: I download some EncoderMagic.app (for example), I double click it to launch it. I select the folder with my numbered images, and out pops my movie. No mess. No resizing. ... Perhaps this doesn't exist (or is called QuickTime Pro?)

• OpenVZ multiple networks on CTs

  - by picca

  I have Hardware Node (HN) which has 2 physical interfaces (eth0, eth1). I'm playing with OpenVZ and want to let my containers (CTs) have access to both of those interfaces. I'm using basic configuration - venet. CTs are fine to access eth0 (public interface). But I can't get CTs to get access to eth1 (private network). I tried: # on HN vzctl set 101 --ipadd 192.168.1.101 --save vzctl enter 101 ping 192.168.1.2 # no response here ifconfig # on CT returns lo (127.0.0.1), venet0 (127.0.0.1), venet0:0 (95.168.xxx.xxx), venet0:1 (192.168.1.101) I believe that the main problem is that all packets flows through eth0 on HN (figured out using tcpdump). So the problem might be in routes on HN. Or is my logic here all wrong? I just need access to both interfaces (networks) on HN from CTs. Nothing complicated.

  I have a bunch of stereo MP3s I'd like to convert to mono. What is the best way to do this? I would prefer something that would let be batch process them. I want to keep the quality as close to the original as possible. My files are also in different bitrates, so I don't want to make all files 320kpbs when some are only 128. Also, is there any quick way to see which files are stereo out of my entire library?
