  • Setting up Google Analytics for multiple subdomains

    - by Andrew G. Johnson
    so first here's a snippet of my current Analytics javascript: var _gaq = _gaq || []; _gaq.push(['_setAccount', 'UA-30490730-1']); _gaq.push(['_setDomainName', '.apartmentjunkie.com']); _gaq.push(['_setSiteSpeedSampleRate', 100]); _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); })(); So if you wanna have a quick peak at the site the url is ApartmentJunkie.com, keep in mind the site is pretty bare bones but you'll get the idea -- basically it's very similar to craigslist in the sense that it's in the local space so people pick a city then get sent to a subdomain that is specific for that city, e.g. winnipeg.mb.apartmentjunkie.com. I put that up late last night then had a look at the analytics and found that I am seeing only the request uri portion of the URLs in analytics as I would with any other site only with this one it's a problem as winnipeg.mb.apartmentjunkie.com/map/ and brandon.mb.apartmentjunkie.com/map/ are two different pages and shouldn't be lumped together as /map/ I know the kneejerk response is likely going to be "hey just setup a different google analytics profile for each subdomain" but there will eventually be a lot of subdomains so google's cap of 50 is going to be too limited and even more important I want to see the data in aggregate for the most part. I am thinking of making a change to the javascript, to something like: _gaq.push(['_trackPageview',String(document.domain) + String(document.location)]); But am unsure if this is the best way and figured someone else on wm.se would have had a similar situation that they could talk a bit about.

  • Is unit testing or test-driven development worthwhile?

    - by Owen Johnson
    My team at work is moving to Scrum and other teams are starting to do test-driven development using unit tests and user acceptance tests. I like the UATs, but I'm not sold on unit testing for test-driven development or test-driven development in general. It seems like writing tests is extra work, gives people a crutch when they write the real code, and might not be effective very often. I understand how unit tests work and how to write them, but can anyone make the case that it's really a good idea and worth the effort and time? Also, is there anything that makes TDD especially good for Scrum?

  • Where does the "mm" come from in GTKmm, glibmm, etc

    - by Cole Johnson
    I understand that the "mm" suffix [in various GTK-associated C++ binding libraries] means "minus minus," but where exactly does it come from? I understand that there is a programming language called "C--," but if there were bindings (and I'm pretty sure I've seen some), they would be suffixed "--". TL;DR: Is there some page on gnu.org that explains the "mm" suffix in various C++ bindings or is it just a de facto standard adopted by the open source community with no reasoning behind it?

  • Is eCPMs dropping by about 50% in January a usual behavior on Google AdSense?

    - by Andrew G. Johnson
    So I just got semi-serious about running some AdSense sites over the past 6 months and the eCPM's have hovered between 1.38 and 1.42 [yes it's that close] when I look at the eCPM for each month. Obviously some deviation day to day but pretty damn close to a buck forty in aggregate. So far for January I am sitting at 0.80 for an eCPM. I know it's not a huge sample size but the daily pageviews are fairly consistent [actually a bit higher] than where they were in December. I am trying to justify this by thinking that somehow a lot of ad buyers buy inventory for the year and have to get setup to do another big buy now that it's a new calendar year but that thought isn't close to comforting. Is this happening to anyone else? EDIT: I run a lot of websites and the ratios of pageviews are about the same this month to last month but just to be clear the eCPM I posted is for 20 websites in a variety of niches, it doesn't accurately depict any one domain.

  • Why do operating systems do low level stuff in C and C++? Why not just C++?

    - by Cole Johnson
    On the Wikipedia page for Windows, it states the Windows is written in Assembly for the bootloader and task switcher, and C and C++ for kernel routines. This confuses me because AFAIK, you can call C++ functions from an extern "C"'d block as C++ is just C with extra features (all of which can be rewritten in C if you wanted to AFAIK). I can get using C for the kernel functions so pure C apps can use them (like printf and such), but if they can just be wrapped in an extern "C " block, then why code in C? So my question is: Why would a kernel be written in both C and C++ instead of just C++

  • How Can I Know Whether I Am a Good Programmer?

    - by Kristopher Johnson
    Like most people, I think of myself as being a bit above average in my field. I get paid well, I've gotten promotions, and I've never had a real problem getting good references or getting a job. But I've been around enough to notice that many of the worst programmers I've worked with thought they were some of the best. Bad programmers who are surrounded by other bad programmers seem to be the most self-deluded. I'm certainly not perfect. I do make mistakes. I do miss deadlines. But I think I make about the same number of bonehead moves that "other good programmers" do. The problem is that I define "other good programmers" to mean "people who are like me." So, I wonder, is there any way a programmer can make some sort of reasonable self-evaluation? How do we know whether we are good or bad at our jobs? Or, if terms like good and bad are too ill-defined, how can programmers honestly identify their own strengths and weaknesses, so that they can take advantage of the former and work to improve the latter?

  • Understanding hand written lexers

    - by Cole Johnson
    I am going to make a compiler for C (C99; I own the standards PDF), written in C (go figure) and looking up on how compilers work on Wikipedia has told me a lot. However, after reading up on lexers has confused me. The Wikipedia page states that: the GNU Compiler Collection (gcc) uses hand-written lexers I have tried googling what a hand written lexer and have come up with nothing except for "making a flowchart that describes how it should function", however, isn't that how all software development should be done? So my question is: "What is a hand written lexer?"

  • What is the difference between WCF service and a simple Web service in developing using .NET Framework?

    - by Steve Johnson
    My questions are: What is the difference between WCF service and a simple Web service in .NET Framework? What a WCF Service can do which a .NET Web service cant? In other words, what are the limitation of .NET Web services which were overcome in WCF services? I understand that WCF are REST based and .NET web services are SOAP based. But I need to know more than that. How a developer will make a design decision whether to developer a Web service or a WCF service?

  • Design Patterns - Why the need for interfaces?

    - by Kyle Johnson
    OK. I am learning design patterns. Every time I see someone code an example of a design pattern they use interfaces. Here is an example: http://visualstudiomagazine.com/Articles/2013/06/18/the-facade-pattern-in-net.aspx?Page=1 Can someone explain to me why was the interfaces needed in this example to demonstrate the facade pattern? The program work if you pass in the classes to the facade instead of the interface. If I don't have interfaces does that mean

    - by Eric Johnson
    Suggested steps to fix the nasty Windows power management issue of plugged in not charging. Option 1: Disconnect AC Shutdown Remove battery Connect AC Startup Under the Batteries category, right-click all of the Microsoft ACPI Compliant Control Method Battery listings, and select Uninstall (it’s ok if you only have 1). Shutdown Disconnect AC Insert battery Connect AC Startup Option 2: Turn off laptop. Unplug AC power. Remove battery. Replace AC power. Turn on laptop, allow OS to boot. Once logged in to the machine, perform a normal shut down. Unplug AC power. Replace battery. Replace AC power. Turn on laptop, allow OS to boot. The battery should once again be charging as normal Additional troubleshooting techniques: Check battery charging status in the BIOS Update BIOS Replace Battery (I did this and the new battery is not charging) See if the battery charging light works when the laptop is powered down.

  • How to Mentor a Junior Developer

    - by Josh Johnson
    This title is a little broad but I may need to give a little background before I can ask my question properly. I know that similar questions have been asked here already. But in my case I'm not asking if I should be mentoring someone or if the person is a good fit for being a software developer. That is not my place to judge. I have not been asked outright, but it is apparent that myself and other fellow senior developers are to mentor the new developers that start here. I have no problem with this whatsoever and, in many cases, it lends me a fresh perspective on things and I end up learning in the process. Also, I remember how beneficial it was in the beginning of my career when someone would take some time to teach me something. When I say "new developer" they could be anywhere from fresh out of college to having a year or two of experience. Recently and in the past we've had people start here who seem to have an attitude toward development/programming which is different from mine and hard for me to reconcile; they seem to extract just enough information to get the task done but not really learn from it. I find myself going over and over the same issues with them. I understand that part of this could be a personality thing, but I feel it's my job to do my best and sort of push them out of the nest while they're under my wing, so to speak. How can I impart just enough information so that they will learn but not give so much as to solve the problem for them? Or perhaps: What's the proper response to questions that are designed to take the path of least resistance and, in essence, force them to learn instead of take the easy way out? These questions are probably more general teaching questions and don't have that much to do specifically with software development. Note: I do not get a say in what tasks they are working on. Management doles the task out and it could be anything from a very simple bug fix to starting an entire application by themselves. While this is not ideal by any means and obviously presents its own gauntlet of challenges, I feel it's a topic best left for another question. So the best I can do is help them with the problem at hand and try to help them break it down into simpler problems and also check their commit logs and point out mistakes that they made. My main objectives are to: Help them out and give them the tools they need to start becoming more self-reliant. Steer them in the right direction and break bad development habits early on. Lessen the amount of time I spend with them (the personality type described above seems to need much more one-on-one time and does not do well over IM or email. While that's generally fine, I can't always stop what I'm working on, break my stride, and help them debug an error on a moments notice; I have my own projects that need to get done).

  • Coding a web browser on Windows using a layout engine?

    - by samual johnson
    I've never attempted anything like this before but what I want to do is code a browser for Windows. I know that I can use the web-browser control that Microsoft has released, but I'm interested in seeing how the problem is solved from a lower level. So I want to know what layout engine I should be looking at? Or is a layout engine the best way to go? I've been looking at WebKit, but it seems rather Mac-centric, so I'm wondering if there are any more practical one's for windows? Has Microsoft released the source code for their webbrowser winforms control in the .Net framework? That would be dependent on the CLR anyway, I suppose? Any suggestions?

  • Color Picking Troubles - LWJGL/OpenGL

    - by Tom Johnson
    I'm attempting to check which object the user is hovering over. While everything seems to be just how I'd think it should be, I'm not able to get the correct color due to the second time I draw (without picking colors). Here is my rendering code: public void render() { glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glLoadIdentity(); camera.applyTranslations(); scene.pick(); glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glLoadIdentity(); camera.applyTranslations(); scene.render(); } And here is what gets called on each block/tile on "scene.pick()": public void pick() { glColor3ub((byte) pickingColor.x, (byte) pickingColor.y, (byte) pickingColor.z); draw(); glReadBuffer(GL_FRONT); ByteBuffer buffer = BufferUtils.createByteBuffer(4); glReadPixels(Mouse.getX(), Mouse.getY(), 1, 1, GL_RGBA, GL_UNSIGNED_BYTE, buffer); int r = buffer.get(0) & 0xFF; int g = buffer.get(1) & 0xFF; int b = buffer.get(2) & 0xFF; if(r == pickingColor.x && g == pickingColor.y && b == pickingColor.z) { hovered = true; } else { hovered = false; } } I believe the problem is that in the method of each tile/block called by scene.pick(), it is reading the color from the regular drawing state, after that method is called somehow. I believe this because when I remove the "glReadBuffer(GL_FRONT)" line from the pick method, it seems to almost fix it, but then it will also select blocks behind the one you are hovering as it is not only looking at the front. If you have any ideas of what to do, please be sure to reply!/ EDIT: Adding scene.render(), tile.render(), and tile.draw() scene.render: public void render() { for(int x = 0; x < tiles.length; x++) { for(int z = 0; z < tiles.length; z++) { tiles[x][z].render(); } } } tile.render: public void render() { glColor3f(color.x, color.y, color.z); draw(); if(hovered) { glColor3f(1, 1, 1); glPolygonMode(GL_FRONT_AND_BACK, GL_LINE); draw(); glPolygonMode(GL_FRONT_AND_BACK, GL_FILL); } } tile.draw: public void draw() { float x = position.x, y = position.y, z = position.z; //Top glBegin(GL_QUADS); glVertex3f(x, y + size, z); glVertex3f(x + size, y + size, z); glVertex3f(x + size, y + size, z + size); glVertex3f(x, y + size, z + size); glEnd(); //Left glBegin(GL_QUADS); glVertex3f(x, y, z); glVertex3f(x + size, y, z); glVertex3f(x + size, y + size, z); glVertex3f(x, y + size, z); glEnd(); //Right glBegin(GL_QUADS); glVertex3f(x + size, y, z); glVertex3f(x + size, y + size, z); glVertex3f(x + size, y + size, z + size); glVertex3f(x + size, y, z + size); glEnd(); } (The game is like an isometric game. That's why I only draw 3 faces.)

  • Sidebar for Navigation in Website

    - by Johnson Smith
    I want to have a sidebar in my website with navigation in it. I will use script like phpBB etc. but I want sidebar to be displayed on every page. So I am thinking about making a Sidebar in HTML and then using frame tag for displaying other pages/scripts. But as Frames are getting obsolute, Is there any other method to display a sidebar in everypage without using frames and without adding html coding on every page?

  • What is the best book for the preparation of MCPD Exam 70-564 (Designing and Developing ASP.NET 3.5 Applications)?

    - by Steve Johnson
    Hi all, I have seen a couple of questions like this one and scanned through the answers but somehow the replies were not satisfactory or practical. So i wondered maybe people who have gone through it and may suggest a better approach for the preparation of this exam. Goal: My goal is actually NOT merely to pass that exam. I intend to actually master the skill. I have been into asp.net web development for approximately 1.5 years and I want to study something that really improves "Design and Development Skills" in Web Development in general and asp.net to be specific which i can put to use and build upon that. Please suggest a book that teaches professional Asp.Net design and development skills and approaches to quality development by taking through practice design scenarios and their solutions and through various case studies that involve design problems and their implemented solutions. Edit: I have found the Micorosoft training kits to be fairly interesting and helpful as these tend to increase knowledge. I have utilized a lot of things after getting a good explanation of things from the training kits. However, as far as Microsoft Training Kit for 70-564 is concerned, there are not a lot of good reviews about it. What i have read and searched on the net , the reviews on amazon and various forums, stack-exchange and experts-exchange, were more inclined to the conclusion that "Microsoft Training Kit for Exam 70-564 is not good. Its is not good as compared to other kits from Microsoft, like as compared to the training kit of Exam 70-562 or others." So i was looking for a proper book containing examples from practical world scenarios and case studies from which i can not only learn but also master the skills before wasting money of Microsoft Training Kit for Exam 70-564. Waiting for experts to provide a suitable advice.

  • Does setting document.domain via script interfere with Google Analytics?

    - by Seth Petry-Johnson
    I have a site, www.example.com, that displays some secure content from forms.example.com in iframes. To enable cross-frame navigation, pages on both sites use JavaScript to set the document.domain to just "example.com". I am using Google Analytics on www.example.com, but the GA site is not showing any data. It indicates that the tracking code is found (the status icon is a green checkmark), but no data is reported. The GA profile lists the website as "www.example.com". Is this a supported scenario? Is my script interfering with the GA code in some way?

  • Chunking large rsync transfers?

    - by Gabe Martin-Dempesy
    We use rsync to update a mirror of our primary file server to an off-site colocated backup server. One of the issues we currently have is that our file server has 1TB of mostly smaller files (in the 10-100kb range), and when we're transferring this much data, we often end up with the connection being dropped several hours into the transfer. Rsync doesn't have a resume/retry feature that simply reconnects to the server to pickup where it left off -- you need to go through the file comparison process, which ends up being very length with the amount of files we have. The solution that's recommended to get around is to split up your large rsync transfer into a series of smaller transfers. I've figured the best way to do this is by first letter of the top-level directory names, which doesn't give us a perfectly even distribution, but is good enough. I'd like to confirm if my methodology for doing this is sane, or if there's a more simple way to accomplish the goal. To do this, I iterate through A-Z, a-z, 0-9 to pick a one character $prefix. Initially I was thinking of just running rsync -av --delete --delete-excluded --exclude "*.mp3" "src/$prefix*" dest/ (--exclude "*.mp3" is just an example, as we have a more lengthy exclude list for removing things like temporary files) The problem with this is that any top-level directories in dest/ that are no longer present present on src will not get picked up by --delete. To get around this, I'm instead trying the following: rsync \ --filter 'S /$prefix*' \ --filter 'R /$prefix*' \ --filter 'H /*' \ --filter 'P /*' \ -av --delete --delete-excluded --exclude "*.mp3" src/ dest/ I'm using the show and hide over include and exclude, because otherwise the --delete-excluded will delete anything that doesn't match $prefix. Is this the most effective way of splitting the rsync into smaller chunks? Is there a more effective tool, or a flag that I've missed, that might make this more simple?

  • Ubuntu 12.04: apt-get "failed to fetch"; apt is trying to fetch via old static IP

    - by gabe
    Sample error: W: Failed to fetch http://security.ubuntu.com/ubuntu/dists/precise-security/universe/i18n/Translation-en Unable to connect to 192.168.1.70:8118: Now this was working just fine until I changed the IP this morning. I have the server set to a static IP of 10.0.1.70 and for years it has been 192.168.1.70 - the IP apt-get is trying to use right now. I use privoxy and tor thus the 8118 port. Like I said it all worked until I changed the static IP from 192.168.1.70 to 10.0.1.70. I was forced to do so because of router issues. (Long and involved story, I didn't really want to change the IP because I know something like this would happen.) The setup for TOR/Privoxy requires that has you point Privoxy at TOR via 127.0.0.1:9050. Then point curl, etc to Privoxy via $HOME/.bashrc. Typically you would set the listen to IP for Privoxy to 127.0.0.1 but if you want it accessible to the rest of the LAN you set the IP to the server's LAN IP. Which I did a long time ago and was working fine until this morning. I have changed all instances of 192.168.1.70 to 10.0.1.70 in both /etc/privoxy/config and $HOME/.bashrc. What makes this really strange for me is that curl is working fine. I curl icanhazip.com and voila I get a new IP every 10 minutes or so. I curl CNN.com and I get the short but sweet permanently moved to www.cnn.com message I expect. Firefox works fine. Ping works fine. And I've tested all of this via Remote Desktop over my LAN. So the connection appears to be fine for everything except apt. I've also rebooted hoping that would clear 192.168.1.70 from apt. So the connection to the internet and DNS aren't an issue for these programs. And they are, as far as I can tell, using Privoxy/TOR just fine. The real irony here is that I've tried to open up Privoxy to go to Ubuntu's servers directly without going through TOR to speed up the downloads from Ubuntu (did this months ago). So somewhere that I have not been able to find, apt has stored the IP 192.168.1.70. And 192.168.1.70 is no longer valid. Thanks for the help

  • Can I use nginx to start EC2 instances on demand?

    - by Gabe Hollombe
    TL;DR - Is there a way to make nginx act as an elastic load balancer that will spin up EC2 instances on demand, allowing for the case when periods of no demand mean no instances will be running? Longer explanation - I have an nginx server that proxy_pass'es requests to a server on EC2. This server doesn't get many requests, so I'd like to keep the server spun down during periods of inactivity (I already have a script to do this). Then, when the instance is spun down and nginx gets a request for that instance, it will time out when trying to get a response from it. At this point, can I somehow trigger a shell command on the server to use EC2's command line tools to spin up the instance, then re-try the user's request after it has started?

  • IPTables configuration for Localhost

    - by Gabe Mc
    I have a problem in connecting a JIRA instance running on a cloud server to an instance of MySQL running on the same box. I have configured it previously using quite a few iptables rules, but it seems overly broad/terribly inprecise. I want access to several of localhosts ports from the local machine, but deny it from all other accounts. Currently, my /etc/iptables.rules file looks like: *filter :INPUT DROP [223:17779] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [10161:1120819] # SSH Access -A INPUT -p tcp -m tcp --dport 22 -j ACCEPT -A INPUT -i eth0 -m state --state RELATED,ESTABLISHED -j ACCEPT # Apache2 Access for connecting to Tomcat on port 8080 -A INPUT -p tcp -m tcp --dport 443 -j ACCEPT # MySQL -I INPUT -i lo -p tcp -m tcp --dport mysql -j ACCEPT COMMIT However, this doesn't allow me to log in when I try logging in; it just hangs on: #> mysql -u root -p -h 127.0.0.1 The Tomcat servlet container starts throwing all kinds of exceptions, as well. This is a more general problem, as I need to enable things like accessing the shutdown port for the Tomcat container, but I need to at least get the MySQL part ironed out first, without the ugliness I was originally trying. Thanks.

  • How to embed video in powerpoint with relative paths?

    - by Gabe
    Does anyone know how to embed a video in a powerpoint presentation in such a way that it can be moved to another computer? Possible solutions I'm considering: Actually embed the video file into the powerpoint file. This would be ideal, but I don't know how to do this. Insert a reference to the video into the presentation. I need this to be a relative path, though, not an absolute path. EDIT: I forgot to mention I'm using powerpoint 2003

  • Why are my at jobs running immediately on OS X?

    I want to schedule events for exact times in Mac OS X. It seems like the 'at' command is the simplest way to do this. I have enabled atrun using the command: launchctl load -w /System/Library/LaunchDaemons/com.apple.atrun.plist To test at, I'm using the following one-line BASH script: echo 'foo' path/to/log.txt | at now + 2 minutes When I run the script, I get output like: job 17 at Sat May 15 12:57:00 2010 where '12:57:00' is indeed 2 minutes in the future. But the echo command executes immediately: the line 'foo' is added to log.txt right away. How can I make at work for me?

  • Setting up router: I can get online via Ethernet, and I can connect to router wirelessly, but can't

    - by Gabe
    I'm setting up a new D-Link N300 router, and trying to connect a MacBook Pro and a MacBook, both running OS X 10.6. As the question says, either computer can connect to the internet when connected to the router via Ethernet. And either one can get on the router's wireless network. But when connected wirelessly (without the Ethernet cable plugged in), neither one can get online. I can't figure out why that would be. Any help appreciated.
