• LINQ into SortedList

  - by Chris Simmons

  I'm a complete LINQ newbie, so I don't know if my LINQ is incorrect for what I need to do or if my expectations of performance are too high. I've got a SortedList of objects, keyed by int; SortedList as opposed to SortedDictionary because I'll be populating the collection with pre-sorted data. My task is to find either the exact key or, if there is no exact key, the one with the next higher value. If the search is too high for the list (e.g. highest key is 100, but search for 105), return null. // The structure of this class is unimportant. Just using // it as an illustration. public class CX { public int KEY; public DateTime DT; } static CX getItem(int i, SortedList<int, CX> list) { var items = (from kv in list where kv.Key >= i select kv.Key); if (items.Any()) { return list[items.Min()]; } return null; } Given a list of 50,000 records, calling getItem 500 times takes about a second and a half. Calling it 50,000 times takes over 2 minutes. This performance seems very poor. Is my LINQ bad? Am I expecting too much? Should I be rolling my own binary search function?

• Is there a problem with scrollTop in Chrome?

  - by Shaun

  I am setting scrollTop and scrollLeft for a div that I am working with. The code looks like this: div.scrollLeft = content.cx*scalar - parseInt(div.style.width)/2; div.scrollTop = content.cy*scalar - parseInt(div.style.height)/2; This works just fine in FF, but only scrollLeft works in chrome. As you can see, the two use almost identical equations and as it works in FF I am just wondering if this is a problem with Chrome? Update: If I switch the order of the assignments then scrollTop will work and scrollLeft won't. <div id="container" style = "height:600px; width:600px; overflow:auto;" onscroll = "updateCenter()"> <script> var div = document.getElementById('container'); function updateCenter() { svfdim.cx = (div.scrollLeft + parseFloat(div.style.width)/2)/scalar; svfdim.cy = (div.scrollTop + parseFloat(div.style.height)/2)/scalar; } function updateScroll(svfdim, scalar, div) { div.scrollTop = svgdim.cy*scalar - parseFloat(div.style.height)/2; div.scrollLeft = svgdim.cx*scalar - parseFloat(div.style.width)/2; } function resizeSVG(Root) { Root.setAttribute("height", svfdim.height*scalar); Root.setAttribute("width", svfdim.width*scalar); updateScroll(svgdim, scalar, div); } </script>

• Draw LINE_STRIP with Unity

  - by Boozzz

  For a new project I am thinking about whether to use OpenGL or Unity3d. I have a bit of experience with OpenGL, but I am completely new to Unity. I already read through the Unity documentation and tutorials on the Unity Website. However, I could not find a way to draw a simple Line-Strip with Unity. In the following example (C#, OpenGL/SharpGL) I draw a round trajectory from a predifined point to an obstacle, which can be imagined as a divided circle with midpoint [cx,cy] and radius r. The position (x-y coordinates) of the obstacle is given by obst_x and obst_y. Question 1: How could I do the same with Unity? Question 2: In my new project, I will have to draw quite a lot of such geometric primitives. Does it make any sense to use Unity for those things? void drawCircle(float cx, float cy, float r, const float obst_x, const float obst_y) { float theta = 0.0f, pos_x, pos_y, dist; const float delta = 0.1; glBegin(GL_LINE_STRIP); while (theta < 180) { theta += delta; //get the current angle float x = r * cosf(theta); //calculate the x component float y = r * sinf(theta); //calculate the y component pos_x = x + cx; //calculate current x position pos_y = y + cy; //calculate current y position //calculate distance from current vertex to obstacle dist = sqrt(pow(pos_x - obst_x) + pow(pos_y - obst_y)); //check if current vertex intersects with obstacle if dist <= 0 { break; //stop drawing circle } else { glVertex2f(pos_x, pos_y); //draw vertex } } glEnd(); }

• Can't get my OpenVpn client to connect

  - by Larry

  Hi Guys, I am trying to setup a test vpn between my home desktop and my laptop. So far I have got the server on the desktop to connect fine but I can not get my laptop to finish the connection. I have tried several different configurations and they all give me the same result. Obviously it has nothing to do with my Client configuration but possibly something on my laptop? Here is the message I get in the log when it stops then times out and restarts.

• openvpn TCP/UDP slow SSH/SMB performance

  - by Petr Latal

  I have question about strange behavior of my openVPN configuration on Debian lenny. I have 2 server configs (one proto tcp-server based and one proto udp based). ISP bandwidth is 7Mbit/7Mbit. When I uses proto tcp-server my download server rate is fine around 6,4 Mbit/s, but upload rate is about 3Mbit/s. When I uses proto udp, my download server rate is around 3Mbit/s and upload rate around 6,4Mbit/s. I tried to handle the MTU, MSSFIX and cipher on/off on server and client configs to synchronize rates, but without solution. Here is TCP based SERVER config: mode server tls-server port 1194 proto tcp-server dev tap0 ifconfig 11.10.15.1 255.255.255.0 ifconfig-pool 11.10.15.2 11.10.15.20 255.255.255.0 push "route 192.168.1.0 255.255.255.0" push "dhcp-option DNS 192.168.1.200" push "route-gateway 11.10.15.1" push "dhcp-option WINS 192.168.1.200" route-up /etc/openvpn/routeup.sh duplicate-cn ca /etc/openvpn/ca.crt cert /etc/openvpn/server.crt key /etc/openvpn/server.key dh /etc/openvpn/dh2048.pem log-append /var/log/openvpn.log status /var/run/vpn.status 10 user nobody group nogroup keepalive 10 120 comp-lzo verb 3 script-security 3 plugin /usr/lib/openvpn/openvpn-auth-pam.so system-auth persist-tun persist-key mssfix cipher BF-CBC Here is UDP based SERVER config: port 1194 proto udp dev tun0 local xx.xx.xx.xx server 11.10.15.0 255.255.255.0 ca /etc/openvpn/ca.crt cert /etc/openvpn/server.crt key /etc/openvpn/server.key dh /etc/openvpn/dh2048.pem log-append /var/log/openvpn.log status /var/run/vpn.status 10 user nobody group nogroup keepalive 10 120 comp-lzo verb 3 duplicate-cn script-security 3 plugin /usr/lib/openvpn/openvpn-auth-pam.so system-auth persist-tun persist-key tun-mtu 1500 mssfix 1212 client-to-client ifconfig-pool-persist ipp.txt Here is TCP/UDP based windows CLIENT config: remote xx.xx.xx.xx --socket-flags TCP_NODELAY tls-client port 1194 proto tcp-client #proto udp dev tap #dev tun pull ca ca.crt cert latis.crt key latis.key mute 0 comp-lzo adaptive verb 3 resolv-retry infinite nobind persist-key auth-user-pass auth-nocache script-security 2 mssfix cipher BF-CBC

• Run script before shutdown/restart

  - by dtbarne

  I'd like to run a PHP script when an instance is told to shutdown, but of course before it actually finishes shutting down. My particular script is just looking to push some log files from the local partition to a another server. I've got the gist of how this process works, but I need some clarification. How I understand it. Please correct me if I'm wrong. Create an executable script in /etc/init.d (lets call it /etc/init.d/push-logs) Create a symlink to /etc/init.d/push-logs from /etc/rc0.d (shutdown) and /etc/rc6.d (reboot). The name should be KXXpush-logs Here's my questions: Of course - am I understanding correctly? For #2 above - it sounds like the lower the XX the better - is there too low a number I can use? Does it matter if it shares a number with another script? Does the script in /etc/init.d/push-logs HAVE to follow the standard init.d template (supporting start/stop, etc. commands)? This doesn't really apply to my use case. If possible I just want the script to be the following: #!/bin/sh # # Run PHP file prior to shutdown # /usr/bin/php /path/to/php_file.php

• Can OpenVPN invoke DHCP Client?

  I have got working VPN connection through openvpn, but I would like to use also my DHCP server and not openvpn's push feature. Currently everything works fine, but I have to manually start dhcp client, eg. dhclient tap0 and I get IP and other important stuff from my DHCP, is there any directive which start DHCP Client when connection is established?

• OpenVPN Client timing out

  - by Austin

  I recently installed OpenVPN on my Ubuntu VPS. Whenenver I try to connect to it, I can establish a connection just fine. However, everything I try to connect to times out. If I try to ping something, it will resolve the IP, but will time out after resolving the IP. (So DNS Server seems to be working correctly) My server.conf has this relevant information (At least I think it's relevant. I'm not sure if you need more or not) # Which local IP address should OpenVPN # listen on? (optional) ;local a.b.c.d # Which TCP/UDP port should OpenVPN listen on? # If you want to run multiple OpenVPN instances # on the same machine, use a different port # number for each one.

• Master does not appear to be a git repository error

  - by EmmyS

  I've inherited a position and instructions for creating a new git repository. Unfortunately I've run into problems and no one here knows what to do. Hoping someone can help me out. Here are the instructions I was left: Create a new repository: For these steps you need to be in the gitosis-admin repository, if you don't have it, in a suitable parent folder do: git clone [email protected]:gitosis-admin.git Edit gitosis.conf file - in gitosis-admin root, under [group base-repo] section, add the name of the new repo to the end of the "writable =" section. Commit change and push back to gitosis-admin master. For the next commands, my_new_project represents the name of your project mkdir my_new_project cd my_new_project git init Copy in any files you want to use to start the repo git commit -a -m "Initializing new repository" git remote add origin [email protected]:my_new_project.git git push master git push master:qa So I did 1 and 2, with no problem. It created a local folder on my machine called gitosis-admin. I edited the gitosis.conf file as indicated. But when I try to do step 3 (which I assume is git push gitosis-admin master) bash tells me that fatal: 'master' does not appear to be a git repository fatal: The remote end hung up unexpectedly What am I doing wrong?

It appears there are problems with the grammar that I have so far been unable to spot.

• Ubuntu 12.04.2 Dual boot UEFI Windows 8 Preinstalled CX21903W Ultrabook

  - by user180782

  Hi i have a problem trying to install ubuntu. The machine is a CX Ultrabook model CX.21903W Intel I5 with 500GB hard disk, 8 GB ram and 32 GB SSD. From Installing Ubuntu on a Pre-Installed Windows 8 (64-bit) System (UEFI Supported), and according to the steps guide: 1 - We create a partition from Win8 (70 GB) from the own win8 program. 2 - Confirm-SecureBootUEFI=True. 3 - From Win8, shift + Restart and from special menu we selected the UEFI Firmware Setting. 4 - From BIOS Option: ------Option 1) Disable Secure Boot. ------Option 2) Disable UEFI (Not Available) from Option 1: Three ways is available. With Secure Boot enable - We can't even boot ubuntu. A red windows saying Soft unproper signed. With Secure Boot disable - and this config in boot device order: ----1: UEFI: USB ----2: Windows Boot Manger ----3: Others and CSM (Compatibility Support Module): enable - GRUB appears and selecting try Ubuntu then a black windows appears and nothing happens. The same result if install ubuntu is selected. With Secure Boot disable - and this config in boot device order: ----1: USB (No UEFI) ----2: Windows Boot Manger ----3: Others and CSM (Compatibility Support Module): enable - GRUB appears and selecting try Ubuntu, - Ubuntu boots and we can install it even. 5 - Rebooting and just changing the boot order as ----1: Ubuntu [] ----2: Windows Boot Manger ----3: Others then nothings happens. 6 - Booting from LiveUSB again and, as per instructed, making Boot-Repair (A warning windows: Ubuntu is working in legacy mode.). 7 - Saving changes and rebooting, Grub works but selecting Ubuntu, a black windows appears and nothing happens. Selecting Win8, Win8 boots and works. Untill now we can't make the ubuntu installation. Any suggestion will be welcomed. kind regards and thanks in advance.

• Customer Service Experience, Oracle e Cels insieme per innovare le strategie.

  - by Claudia Caramelli-Oracle

  Si è svolto oggi il workshop Oracle "Customer Service Experience. Strategie per progettare un Servizio eccellente e profittevole." che ha visto il contributo del gruppo di ricerca CELS (Research Group on Industrial Engineering, Logistics and Service Operations) e della sezione ASAP SMF dell’Università degli Studi di Bergamo. Giuditta Pezzotta (PhD - Cels) e Roberto Pinto (PhD - Cels) ci hanno presentato la Service Engineering Methodology (SEEM), innovativa piattaforma metodologica che permette di ottimizzare la creazione di valore sia per il cliente finale sia per l’azienda, partendo dalla progettazione del prodotto e arrivando alla progettazione della soluzione prodotto-servizio, e valutando la bontà del prodotto-servizio ipotizzato attraverso strumenti concettuali e di simulazione dei processi. Armando Janigro, CX Strategy Director EMEA - Oracle ha invece parlato di Modern Customer Service, ovvero di come adattarsi in modo agile e veloce alle mutevoli necessità dei clienti, ipotizzando l’adozione in chiave strategica di nuovi strumenti di differenziazione e di leadership come la Customer Experience (CX) e sfruttando le nuove dinamiche di relazione azienda-singolo consumatore per ottimizzare l’esperienza multicanale e per render più efficiente il Customer Service, creando ulteriore valore. A seguire è stata mostrata da PierLuigi Coli, Principal Sales Consultant - Oracle, una demo sui prodotti Service Cloud offerti da Oracle, a supporto di tutti i concetti raccontati nelle sessioni precedenti. Il workshop è stato un’occasione unica per definire i percorsi da intraprendere per sviluppare efficaci strategie di Customer Experience grazie ad approcci e metodologie innovative alla base di uno sviluppo sostenibile del business. Le slide proiettate sono disponibili su richiesta: scrivi a Claudia Caramelli per ogni informazione o chiarimento.

• Understanding dot notation

  - by Starkers

  Here's my interpretation of dot notation: a = [2,6] b = [1,4] c = [0,8] a . b . c = (2*6)+(1*4)+(0*8) = 12 + 4 + 0 = 16 What is the significance of 16? Apparently it's a scalar. Am I right in thinking that a scalar is the number we times a unit vector by to get a vector that has a scaled up magnitude but the same direction as the unit vector? So again, what is the relevance of 16? When is it used? It's not the magnitude of all the vectors added up. The magnitude of all of them is calculated as follows: sqrt( ax * ax + ay * ay ) + sqrt( bx * bx + by * by ) + sqrt( cx * cx + cy * cy) sqrt( 2 * 2 + 6 * 6 ) + sqrt( 1 * 1 + 4 * 4 ) + sqrt( 0 * 0 + 8 * 8) sqrt( 4 + 36 ) + sqrt( 1 + 16 ) + sqrt( 0 + 64) sqrt( 40 ) + sqrt( 17 ) + sqrt( 64) 6.3 + 4.1 + 8 10.4 + 8 18.4 So I don't really get this diagram: Attempting with sensible numbers: a = [1,0] b = [4,3] a . b = (1*0) + (4*3) = 0 + 12 = 12 So what exactly is a . b describing here? The magnitude of that vector? Because that isn't right: the 'a.b' vector = [4,0] sqrt( x*x + y*y ) sqrt( 4*4 + 0*0 ) sqrt( 16 + 0 ) 4 So what is 12 describing?

• Hosted bug tracking system with mercurial repositories (Summary of options & request for opinions)

  - by Mark Booth

  The Question What hosted mercurial repository/bug tracking system or systems have you used? Would you recommend it to others? Are there serious flaws, either in the repository hosting or the bug tracking features that would make it difficult to recommend it? Do you have any other experiences with it or opinions of it that you would like to share? If you have used other non mercurial hosted repository/bug tracking systems, how does it compare? (If I understand correctly, the best format for this type of community-wiki style question is one answer per option, if you have experienced if several) Background I have been looking into options for setting up a bug/issue tracking database and found some valuable advice in this thread and this. But then I got to thinking that a hosted solution might not only solve the problem of tracking bugs, but might also solve the problem we have accessing our mercurial source code repositories while at customer sites around the world. Since we currently have no way to serve mercurial repositories over ssl, when I am at a customer site I have to connect my laptop via VPN to my work network and access the mercurial repositories over a samba share (even if it is just to synce twice a day). This is excruciatingly slow on high latency networks and can be impossible with some customers' firewalls. Even if we could run a TRAC or Redmine server here (thanks turnkey), I'm not sure it would be much quicker as our internet connection is over-stretched as it is. What I would like is for developers to be able to be able to push/pull to/from a remote repository, servicing engineers to be able to pull from a remote repository and for customers (both internal and external) to be able to submit bug/issue reports. Initial options The two options I found were Assembla and Jira. Looking at Assembla I thought the 'group' price looked reasonable, but after enquiring, found that each workspace could only contain a single repository. Since each of our products might have up to a dozen repositories (mostly for libraries) which need to be managed seperately for each product, I could see it getting expensive really quickly. On the plus side, it appears that 'users' are just workspace members, so you can have as many client users (people who can only submit support tickets and track their own tickets) without using up your user allocation. Jira only charges based on the number of users, unfortunately client users also count towards this, if you want them to be able to track their tickets. If you only want clients to be able to submit untracked issues, you can let them submit anonymously, but that doesn't feel very professional to me. More options Looking through MercurialHosting page that @Paidhi suggested, I've added the options which appear to offer private repositories, along with another that I found with a web search. Prices are as per their website today (29th March 2010). Corrections welcome in the future. Anyway, here is my summary, according to the information given on their websites: Assembla, http://www.assembla.com/, looks to be a reasonable price, but suffers only one repository per workspace, so three projects with 6 repos each would use up most of the spaces associated with a $99/month professional account (20 spaces). Bug tracking is based on Trac. Mercurial+Trac support was announced in a blog entry in 2007, but they only list SVN and Git on their Features web page. Cost: $24, $49, $99 & $249/month for 40, 40, unlimited, unlimited users and 1, 10, 20, 100 workspaces. SSL based push/pull? Website https login. BitBucket, http://bitbucket.org/plans/, is primarily a mercurial hosting site for open source projects, with SSL support, but they have an integrated bug tracker and they are cheap for private repositories. It has it’s own issues tracker, but also integrates with Lighthouse & FogBugz. Cost: $0, $5, $12, $50 & $100/month for 1, 5, 15, 25 & 150 private repositories. SSL based push/pull. No https on website login, but supports OpenID, so you can chose an OpenID provider with https login. Codebase HQ, http://www.codebasehq.com/, supports Hg and is almost as cheap as BitBucket. Cost: £5, £13, £21 & £40/month for 3, 15, 30 & 60 active projects, unlimited repositories, unlimited users (except 10 users at £5/month) and 0.5, 2, 4 & 10GB. SSL based push/pull? Website https login? Firefly, http://www.activestate.com/firefly/, by ActiveState looks interesting, but the website is a little light on details, such as whether you can only have one repository per project or not. Cost: $9, $19, & £39/month for 1, 5 & 30 private projects, with a 0.5, 1.5 & 3 GB storage limit. SSL based push/pull? Website https login. Jira, http://www.atlassian.com/software/jira/, isn’t limited by the number of repositories you can have, but by ‘user’. It could work out quite expensive if we want client users to be able to track their issues, since they would need a full user account to be created for them. Also, while there is a Mercurial extension to support jira, there is no ‘Advanced integration’ for Mercurial from Atlassian Fisheye. Cost: $150, $300, $400, $500, $700/month for 10, 25, 50, 100, 100+ users. SSL based push/pull? Website https login. Kiln & FogBugz On Demand, http://fogcreek.com/Kiln/IntrotoOnDemand.html, integrates Kilns mercurial DVCS features with FogBugz, where the combined package is much cheaper than the component parts. Also, the Fogbugz integration is supposedly excellent. *8’) Cost: £30/developer/month ($5/d/m more than either on their own). SSL based push/pull? SourceRepo, http://sourcerepo.com/, also supports HG and is even cheaper than BitBucket & Codebase. Cost: $4, $7 & $13/month for 1, unlimited & unlimited repositories/trac/redmine instances and 500MB, 1GB & 3GB storage. SSL based push/pull. Website https login. Edit: 29th March 2010 & Bounty I split this question into sections, made the questions themselves more explicit, added other options from the research I have done since my first posting and made this community wiki, since I now understand what CW is for. *8') Also, I've added a bounty to encourage people to offer their opinions. At the end of the bounty period, I will award the bounty to whoever writes the best review (good or bad), irrespective of the number of up/down votes it gets. Given that it's probably more important to avoid bad providers than find the absolute best one, 'bad reviews' could be considered more important than good ones.

• git | error: Unable to append to .git/logs/refs/remotes/origin/master: Permission denied [SOLVED]

  - by Corbin Tarrant

  I am having a strange issue that I can't seem to resolve. Here is what happend: I had some log files in a github repository that I didn't want there. I found this script that removes files completely from git history like so: #!/bin/bash set -o errexit # Author: David Underhill # Script to permanently delete files/folders from your git repository. To use # it, cd to your repository's root and then run the script with a list of paths # you want to delete, e.g., git-delete-history path1 path2 if [ $# -eq 0 ]; then exit 0are still fi # make sure we're at the root of git repo if [ ! -d .git ]; then echo "Error: must run this script from the root of a git repository" exit 1 fi # remove all paths passed as arguments from the history of the repo files=$@ git filter-branch --index-filter "git rm -rf --cached --ignore-unmatch $files" HEAD # remove the temporary history git-filter-branch otherwise leaves behind for a long time rm -rf .git/refs/original/ && git reflog expire --all && git gc --aggressive --prune I, of course, made a backup first and then tried it. It seemed to work fine. I then did a git push -f and was greeted with the following messages: error: Unable to append to .git/logs/refs/remotes/origin/master: Permission denied error: Cannot update the ref 'refs/remotes/origin/master'. Everything seems to have pushed fine though, because the files seem to be gone from the GitHub repository, if I try and push again I get the same thing: error: Unable to append to .git/logs/refs/remotes/origin/master: Permission denied error: Cannot update the ref 'refs/remotes/origin/master'. Everything up-to-date EDIT $ sudo chgrp {user} .git/logs/refs/remotes/origin/master $ sudo chown {user} .git/logs/refs/remotes/origin/master $ git push Everything up-to-date Thanks! EDIT Uh Oh. Problem. I've been working on this project all night and just went to commit my changes: error: Unable to append to .git/logs/refs/heads/master: Permission denied fatal: cannot update HEAD ref So I: sudo chown {user} .git/logs/refs/heads/master sudo chgrp {user} .git/logs/refs/heads/master I try the commit again and I get: error: Unable to append to .git/logs/HEAD: Permission denied fatal: cannot update HEAD ref So I: sudo chown {user} .git/logs/HEAD sudo chgrp {user} .git/logs/HEAD And then I try the commit again: 16 files changed, 499 insertions(+), 284 deletions(-) create mode 100644 logs/DBerrors.xsl delete mode 100644 logs/emptyPHPerrors.php create mode 100644 logs/trimXMLerrors.php rewrite public/codeCore/Classes/php/DatabaseConnection.php (77%) create mode 100644 public/codeSite/php/init.php $ git push Counting objects: 49, done.

I jump on http://GitHub.com and check out the repository, and my latest commit is no where to be found. ::scratch head:: So I push again: Everything up-to-date Umm...it doesn't look like it. I've never had this issue before, could this be a problem with github? or did I mess something up with my git project? EDIT Nevermind, I did a simple: git push origin master and it pushed fine.

• TeamCity NuGet private feed - Credentials

  - by Gaui

  I installed TeamCity and enabled NuGet server, both Authenticated Feed and Public Feed. When I try to push packages to the server with the following command: > nuget push package.nupkg [API-Key-here] -s http://myserver/httpAuth/app/nuget/v1/FeedService.svc/ I get the following prompt: Please provide credentials for: http://myserver/httpAuth/app/nuget/v1/FeedService.svc/ And asks me for both "UserName" and "Password". I've tried entering credentials for TeamCity administrator and Windows administrator, but nothing works. So I tried pushing to the Public Feed with the following command: > nuget push package.nupkg [API-Key-here] -s http://myserver/guestAuth/app/nuget/v1/FeedService.svc/ Then I get the following: Failed to process request. 'Method Not Allowed'. The remote server returned an error: (405) Method Not Allowed.. Regarding the Authenticated Feed, what credentials are they and where do I specify them and why is the Public Feed not working?

• How to specify multiple HostName/Port combinations in .ssh/config

  - by leoluk

  I have multiple notebooks and workstations which pull and push from multiple Mercurial repositories on a central server. I usually use .ssh/config to set an alias: Host repo-server HostName server.somedomain User user143 IdentityOnly yes IdentityFile ~/hgkey Port 156 ... and some more options, you get the idea. I can then simply do a hg push ssh://repo-server//hgroot/someproject on every local repository, and I can change the server address and port in one place. For workstations, this works fine, but the notebooks can access the server either from inside the network or from outside, using a different address and a different port. Is there any way I can specify multiple HostName/Port combinations so that SSH automatically tries them in order? This way, the users could push and pull without having to care about the correct address. (of course, using a VPN would be the most correct solution)

• How do I make my play/pause keyboard button work correctly in iTunes 10 on Windows?

  - by EvilChookie

  First and foremost, I have mmKeys installed correctly. My iTunes works almost perfect while minimized to the tray. My problem is with the play/pause button on my Wireless Comfort Keyboard 5000. When iTunes does not have focus (like it's minimized, or if it isn't the application I'm active in, like right now while typing this) the play pause button toggles twice. So, I'll push the pause button - and the song that is playing will pause, but a split second later will start up again. If the song is paused, and I push play, the song will immediately pause again. In order to get the key to work correctly, I must give iTunes focus, and then push the button. Here's a video I created on youtube: http://www.youtube.com/watch?v=POh6Gbm5QZI OS: Windows 7 x64 iTunes: 10.0.0.68 Intellitype: 8.0 Edit: Apparently I have intellitype 8.0 instead of 7.1

• Google Analytics and Whos.amung.us in realtime visitors, why such an enormous discrepancy?

  - by jacouh

  Since years I use in a site both Google Analytics and Whos.amung.us, both Google analytics and whos.amung.us javascripts are inserted in the same pages in the tracked part of the site. In real-time visitors, why such an enormous discrepancy ? for example at the moment, Google analytics gives me 9 visitors, whos.amung.us indicates 59, a ratio of 6 times? Why whos.amung.us is 6 times optimistic than Google Analytics in terms of the realtime visitors? Google whos.amung.us My question is: whos.amung.us does not detect robots while Google does? GA ignores visitors from some countries, not whos.amung.us? Some robots/bots execute whos.amung.us javascript for tracking? While no robots/bots can execute the tracking javascript provided by Google Analytics? To facilitate your analysis, I copy JS code used below: Google analytics: <script type="text/javascript"> var _gaq = _gaq || []; _gaq.push(['_setAccount', 'MyGaAccountNo']); _gaq.push(['_trackPageview']); (function() { var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true; ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s); })(); </script> Whos.amung.us: <script>var _wau = _wau || []; _wau.push(["tab", "MyWAUAccountNo", "c6x", "right-upper"]);(function() { var s=document.createElement("script"); s.async=true; s.src="http://widgets.amung.us/tab.js";document.getElementsByTagName("head")[0].appendChild(s);})();</script> I've aleady signaled this to WAU staff some time ago, NR, I've not done this to Google as they don't handle this kind of feedback. Thank you for your explanations.

• Referral traffic not appearing properly in Google Analytics

  - by Crashalot

  We have a partnership arrangement with another site where we pay them for users sent to us. However, they claim our referral numbers for them are lower than theirs by 50%. They are tracking clicks in Google Analytics (using events) while we are using visits in Google Analytics. Are we doing something wrong with our Google Analytics installation? <!-- Google Analytics BEGIN --> <script type="text/javascript"> var _gaq = _gaq || []; _gaq.push(['_setAccount', 'UA-12345678-1']); _gaq.push(['_setDomainName', 'example.com']); _gaq.push(['_trackPageview']); (function() { var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true; ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s); })(); </script> <!-- Google Analytics END -->
