  • Best SEO practices for mobile URLs: 301, rel=canonical, or something else?

    - by Chris
    I am developing a site with a mobile version and am trying to figure the appropriate way to manage the URLs for search engines. So far I've considered: Having a separate mobile site (m.example.com) with rel="canonical" links to the regular site. Putting both the mobile site and full site on one URL (example.com), and doing user agent sniffing. Another opinion: Spencer: "If you have a mobile site at a separate location or URL, you should 301 redirect each and every mobile page to its corresponding page on your main website. Employ user agent detection so that the mobile optimized version is served up if someone's coming in from a hand-held. - http://developer.practicalecommerce.com/articles/1722-Mobile-site-Development-Best-Practices-for-SEO-Usability Both 2 and 3 make it hard for a user who wants to switch to the full site or mobile site manually, but I'm not sure 1 is the best alternative. What's the best way to write URLs for a mobile site?

  • ASP.NET MVC WebService - Security for Industrial Android Clients

    - by Chris Nevill
    I'm trying to design a system that will allow a bunch of Android devices to securely log into an ASP.NET MVC REST Web service. At present neither side are implemented. However there is an ASP.NET MVC website which the web service will site along side. This is currently using forms authentication. The idea will be that the Android devices will download data from the web service and then be able to work offline storing data in their own local databases, where users will be able to make updates to that data, and then syncing updates back to the main server where possible. The web service will be using HTTPS to prevent calls being intercepted and reduce the risk of calls being intercepted. The system is an industrial system and will not be in used by the general Android population. Instead only authorized Android devices will be authorized by the Web Service to make calls. As such I was thinking of using the Android devices serial number as a username and then a generated long password which the device will be able to pick up - once the device has been authorized server side. The device will also have user logins - but these will not be to log into the web service - just the device itself - since the device and user must be able to work offline. So usernames and passwords will be downloaded and stored on the devices themselves. My question is... what form of security is best setup on the web service? Should it use forms Authentication? Should the username and password just be passed in with each GET/POST call or should it start a session as I have with the website? The Android side causes more confusion. There seems to be a number of options here Spring-Android, Volley, Retrofit, LoopJ, Robo Spice which seems to use the aforementioned Spring, Retrofit or Google HttpClient. I'm struggling to find a simple example which authenticates with a forms based authentication system. Is this because I'm going about this wrong? Is there another option that would better suite this?

  • OpenGL ES Basic Fragment Shader help with transparency

    - by Chris
    I have just spent my first half hour playing with the shader language. I have modified the basic program I have which renders the texture, to allow me to colour the texture. varying vec2 texCoord; uniform sampler2D texSampler; /* Given the texture coordinates, our pixel shader grabs the corresponding * color from the texture. */ void main() { //gl_FragColor = texture2D(texSampler, texCoord); gl_FragColor = vec4(0,1,0,1)*vec4(texture2D(texSampler,texCoord).xyz,1); } I have noticed how this affects my transparent textures, and I believe I am loosing the alpha channel which would explain why previously transparent area's appear totally black. If I use the following line instead, I am shown the transparent area's gl_FragColor = vec4(0,1,0,1)*vec4(texture2D(texSampler,texCoord).aaa,1); How can I retain the transparency after this modification to the colour? I have seen various things about a .w property, and also luminous, but my tweaks with those and the .aaa property are not working XD

  • Beginner Geek: How to Use Multiple Monitors to Be More Productive

    - by Chris Hoffman
    Many people swear by multiple monitors, whether they’re geeks or just people who need to be productive. Why use just one monitor when you can use two or more and see more at once? Additional monitors allow you to expand your desktop, getting more screen real estate for your open programs. Windows makes it very easy to set up additional monitors, and your computer probably has the necessary ports. Why Use Multiple Monitors? Multiple monitors give you more screen real estate. Hook up multiple monitors to a computer and you can move your mouse back and forth between them, dragging programs between monitors as if you had an extra-large desktop. People who swear by multiple monitors use them to display multiple things on-screen at a time. Rather than Alt+Tabbing and task switching to glance at another window, you can just look over with your eyes and then look back to the program you’re using. Some examples of use cases for multiple monitors include: Coders who want to view their code on one display with the other display reserved for documentation. They can just glance over at the documentation and look back at their primary workspace. Anyone who needs to view something while working. Viewing a web page while writing an email, viewing another document while writing an something, or working with two large spreadsheets and having both visible at once. People who need to keep an eye on information, whether it’s email or up-to-date statistics, while working. Gamers who want to see more of the game world, extending the game across multiple displays. Geeks who just want to watch a video on one screen while doing something else on the other screen. Hooking Up Multiple Monitors Hooking up an additional monitor to your computer should be very simple. Most new computers come with more than one port for a monitor — whether DVI, HDMI, the older VGA port, or a mix. Some computers may include splitter cables that allow you to connect multiple monitors to a single port. Most laptops also come with ports that allow you to hook up an external monitor. Plug a monitor into your laptop’s DVI or VGA port and Windows will allow you to use both your laptop’s integrated display and the external monitor at once. This all depends on the ports your computer has and how your monitor connects. If you have an old VGA monitor lying around and you have a modern laptop with only DVI or HDMI connectors, you may need an adapter that allows you to plug your monitor’s VGA cable into the new port. Be sure to take your computer’s ports into account before you get another monitor for it. Managing Multiple Monitors With Windows Windows makes using multiple monitors easy. Just plug the monitor into the appropriate port on your computer and Windows should automatically extend your desktop onto it. You can now just drag and drop windows between monitors. To control how this works, right-click your Windows desktop and select Screen resolution. Choose an option from the Multiple displays box. The Extend option extends your desktop onto an additional monitor, while the other options are mainly useful if you’re using an additional monitor for presentations — for example, you could mirror your laptop’s desktop onto a large monitor or blank your laptop’s screen while it’s connected to a larger display. Be sure to arrange your monitors properly so Windows understands how your monitors are physically positioned. Windows 8 allows you to extend your Windows taskbar across multiple monitors. You’ll find this option in the taskbar’s options window — right-click the taskbar and select Properties. You can also choose where you want Windows to display taskbar buttons for open programs — on any monitor’s taskbar or only on the taskbar on the associated monitor. Windows 7 doesn’t have these convenient features built-in — your second monitor won’t have a taskbar. To extend your taskbar onto an additional monitor, you’ll need a third-party utility like the free and open-source Dual Monitor Taskbar. If you just have a single monitor, you can also use the Aero Snap feature to quickly place multiple Windows applications side by side. On Windows 7 or 8, press Windows Key + Left or Windows Key + Right to make the current window take up the left or right half of your display. You could also drag any window’s title bar to the left or right edges of your screen and release the window. How useful this feature is depends on your monitor’s size and resolution. If you have a large, high-resolution monitor, it will allow you to see a lot. If you have a smaller laptop monitor with the seemingly standard 1366×768 resolution, you won’t be able to see much of each snapped window at once, so snapping windows may not be practical.

  • How to Save Hundreds or Thousands of Dollars on Cell Phone Service

    - by Chris Hoffman
    Cell phone contracts are bad. You get a seemingly cheap phone up front, but you more than pay for the cost of the phone over two years. Prepaid phone plans are surging in North America for a reason. Prepaid phone plans will be cheaper and more flexible than traditional contracts with big carriers for many people. However much you use your phone, there’s a good chance you can save money with a prepaid service. No More Contracts Here’s how cell phone service typically works in North America: You get a subsidized phone for “free”, $99, or $199. You sign up for a two-year contract and more than pay back the cost of that phone over the length of the contract. This is similar to leasing something or purchasing it on a credit card and paying it back over two years — you spend less up front, but you’re paying more in the long run. But this isn’t the only option. You could opt for a cheaper prepaid service that doesn’t lock you into a contract. If you don’t use your phone much, you could just pay for what you use and avoid the hefty cell phone bills. If you use your phone a lot, you could get a cheaper plan, too. Now, this certainly isn’t for everyone. If you want the latest iPhone or Galaxy smartphone every two years and require a 4G data connection, prepaid services may not be for you. On the other hand, if you don’t need the latest phone, you can save money here. You can also save a huge amount of money if you don’t use your phone much. Phone Options When you choose your prepaid or contract-free service, you’ll often be able to purchase a phone from them. You’ll generally be able to find dirt-cheap dumbphones and the cheapest, slowest Android phones for not very much money. If you are able to buy a top-of-the-line smartphone, you’ll have to pay the full, unsubsidized price. That’s $649 for either an iPhone 5S or Samsung Galaxy S4. Whatever phones the service provider offers, you could always buy a phone elsewhere — for example, you could buy an unsubsidized iPhone direct from Apple and then take it to your cell phone service of choice. Most services will allow you to get a SIM card and pop it into your existing phone rather than purchasing a phone. If you can get a hand-me-down smartphone, you can often save quite a bit of money. For example, you may have a family member upgrading from an iPhone 4S to an iPhone 5S. You could take their phone to a prepaid carrier and have a nicer phone on a cheap cell phone plan. If you brought an old smartphone to a big carrier like AT&T or Verizon, they wouldn’t give you a discount on your monthly plan. You’d have to pay the same amount of money every month as if you had gotten a subsidized phone. Google’s Nexus phones are also great options for people looking to buy smartphones and pay up-front. Google’s Nexus 4 offered a modern, almost top-of-the-line Android smartphone experience at $299 or $349 when it came out last year. Google will soon be releasing the Nexus 5 and it’s expected to be priced at $349. That’s certainly a lot more than a cheap phone, but it’s a fairly high-end smartphone at almost half the price of an iPhone 5S or Galaxy S4. Nexus phones can be purchased online from Google’s Play Store. Service Options When choosing a service, you need to consider what you actually use. If you’re someone who only uses your phone rarely, you can get plans that will allow you to pay as little as a few dollars per month. If you’re someone who’s usually in range of Wi-Fi, you may not need much data at all. If you want a plan with unlimited talk, texting, and data usage, you can get it for much cheaper than you’d pay on a major carrier like AT&T. The options here range from pay-as-you-go plans, like the ones offered by T-Mobile, which allow you to put a certain amount of money in and only drain that balance when you actually use minutes, texts, or data. If you only make a few calls and send a few texts per month, you’d only pay a few bucks. On the other end, Walmart’s Straight Talk service is a popular option that offers unlimited talk, texting, and data at $45 per month. Which service is right for you depends on a lot of things, including your usage and what each network’s coverage is like in your area. You’ll want to do some research of your own before choosing a service. Prepaid services also offer you even more flexibility after you choose one. If you’re not happy or a better deal comes along, you can switch — you’re not locked into your service for two years and you won’t pay an early termination fee.

  • Recommendations for adjustable sit-stand workstations?

    - by Chris Phillips
    Recently, I've been feeling the discomfort of sitting at my desk all day long. I'm fairly active, stretch, and take regular breaks, but some days it's still pretty uncomfortable to sit all day long, whether in a nice chair or on an exercise ball. I would really like able to stand at my computer for part of the day. My current setup is a large desk with two 26" lcds and a 17" laptop. I don't mind if the laptop isn't adjustable, as I don't use it as regularly as the monitors. I would like to be able to fairly easily switch from a sitting position to a standing position and back again as necessary. I've been looking into adjustable height desks and stands and found that they tend to be either really expensive, or don't quite meet my needs. (For example, the Ergotron WorkFit-S Dual LCD workstation looks like the ideal feature set at a reasonable price, but won't fit with my monitors.) Any suggestions or thoughts? Update: fixed a typo. Thanks @RDL!

  • Is there a better term than "smoothness" or "granularity" to describe this language feature?

    - by Chris
    One of the best things about programming is the abundance of different languages. There are general purpose languages like C++ and Java, as well as little languages like XSLT and AWK. When comparing languages, people often use things like speed, power, expressiveness, and portability as the important distinguishing features. There is one characteristic of languages I consider to be important that, so far, I haven't heard [or been able to come up with] a good term for: how well a language scales from writing tiny programs to writing huge programs. Some languages make it easy and painless to write programs that only require a few lines of code, e.g. task automation. But those languages often don't have enough power to solve large problems, e.g. GUI programming. Conversely, languages that are powerful enough for big problems often require far too much overhead for small problems. This characteristic is important because problems that look small at first frequently grow in scope in unexpected ways. If a programmer chooses a language appropriate only for small tasks, scope changes can require rewriting code from scratch in a new language. And if the programmer chooses a language with lots of overhead and friction to solve a problem that stays small, it will be harder for other people to use and understand than necessary. Rewriting code that works fine is the single most wasteful thing a programmer can do with their time, but using a bazooka to kill a mosquito instead of a flyswatter isn't good either. Here are some of the ways this characteristic presents itself. Can be used interactively - there is some environment where programmers can enter commands one by one Requires no more than one file - neither project files nor makefiles are required for running in batch mode Can easily split code across multiple files - files can refeence each other, or there is some support for modules Has good support for data structures - supports structures like arrays, lists, and especially classes Supports a wide variety of features - features like networking, serialization, XML, and database connectivity are supported by standard libraries Here's my take on how C#, Python, and shell scripting measure up. Python scores highest. Feature C# Python shell scripting --------------- --------- --------- --------------- Interactive poor strong strong One file poor strong strong Multiple files strong strong moderate Data structures strong strong poor Features strong strong strong Is there a term that captures this idea? If not, what term should I use? Here are some candidates. Scalability - already used to decribe language performance, so it's not a good idea to overload it in the context of language syntax Granularity - expresses the idea of being good just for big tasks versus being good for big and small tasks, but doesn't express anything about data structures Smoothness - expresses the idea of low friction, but doesn't express anything about strength of data structures or features Note: Some of these properties are more correctly described as belonging to a compiler or IDE than the language itself. Please consider these tools collectively as the language environment. My question is about how easy or difficult languages are to use, which depends on the environment as well as the language.

  • Deeper Unity search indexing

    - by Chris Bauer
    Unity is currently only indexing and displaying a shallow set of file results. Suppose I want to open the file "/home/Music/Creedence Clearwater Revival/Willy and the Poor Boys/The-Midnight-Special.mp3". I open the "Files and Folders" lens and type "The Midnight Special". Unfortunately, the song doesn't display. I try "Willy and the Poor Boys" but that folder doesn't display either. The only folder that does display in the lens is "Music". Therefore I must open the "Music" folder then navigate through the entire directory tree to open the file I want. How do I get a deeper index of files to display in the "Files and Folders" lens? Thanks for your help!

  • What languages are most commonly used in medical research?

    - by Chris Taylor
    For someone about to go into a career in medical research, what language would be the most useful to learn? From my limited experience (I have been a researcher in mathematics and in finance) I have been able to recommend looking at R (for statistics) Matlab (for general numeric processing) and Python (for general purpose programming with statistics/numerics as an add-on) but I don't know which of those (if any) are in common use -- or if there are other, more specialized languages that are used. To be clear, I'm not talking about a professional programmer working in a medical setting. I am talking about a medical or genetics researcher who uses programming to analyse data, or generally to help get their work done.

  • 3D Camera Problem

    - by Chris
    I allow the user to look around the scene by holding down the left mouse button and moving the mouse. The problem that I have is I can be facing one direction, I move the mouse up and the view tilts up, I move down and the view titles down. If I spin around 180 my left and right still works fine, but when I move the mouse up the view tilts down, and when I move the mouse down the view titles up. This is the code I am using, can anyone see what the problem with the logic is? var viewDir = g_math.subVector(target, g_eye); var rotatedViewDir = []; rotatedViewDir[0] = (Math.cos(g_mouseXDelta * g_rotationDelta) * viewDir[0]) - (Math.sin(g_mouseXDelta * g_rotationDelta) * viewDir[2]); rotatedViewDir[1] = viewDir[1]; rotatedViewDir[2] = (Math.cos(g_mouseXDelta * g_rotationDelta) * viewDir[2]) + (Math.sin(g_mouseXDelta * g_rotationDelta) * viewDir[0]); viewDir = rotatedViewDir; rotatedViewDir[0] = viewDir[0]; rotatedViewDir[1] = (Math.cos(g_mouseYDelta * g_rotationDelta * -1) * viewDir[1]) - (Math.sin(g_mouseYDelta * g_rotationDelta * -1) * viewDir[2]); rotatedViewDir[2] = (Math.cos(g_mouseYDelta * g_rotationDelta * -1) * viewDir[2]) + (Math.sin(g_mouseYDelta * g_rotationDelta * -1) * viewDir[1]); g_lookingDir = rotatedViewDir; var newtarget = g_math.addVector(rotatedViewDir, g_eye);

  • Fight for your rights as a video gamer.

    - by Chris Williams
    Soon, the U.S. Supreme Court may decide whether to hear a case that could have a lasting impact on computer and video games. The case before the Court involves a law passed by the state of California attempting to criminalize the sale of certain computer and video games. Two previous courts rejected the California law as unconstitutional, but soon the Supreme Court could have the final say. Whatever the Court's ruling, we must be prepared to continue defending our rights now and in the future. To do so, we need a large, powerful movement of gamers to speak with one voice and show that we won't sit back while lawmakers try to score political points by scapegoating video games and treating them differently than books, movies, and music. If the Court decides to hear the case, we're going to need thousands of activists like you who can help defend computer and video games by writing letters to editors, calling into talk radio stations, and educating Americans about our passion for and appreciation of computer and video games. You can help build this movement right now by inviting all your friends and fellow gamers to join the Video Game Voters Network. Use our simple tool to send an email to everyone you know asking them to stand up for gaming rights: http://videogamevoters.org/movement You can also help spread the word through Facebook and Twitter, or you can simply forward this email to everyone you know and ask them to sign up at videogamevoters.org. Time after time, courts continue to reject politicians' efforts to restrict the sale of computer and video games. But that doesn't mean the politicians will stop trying anytime soon -- in fact, it means they're likely to ramp up their efforts even more. To stop them, we must make it clear that gamers will continue to stand up for free speech -- and that the numbers are on our side. Help make sure we're ready and able to keep fighting for our gaming rights. Spread the word about the Video Game Voters Network right now: http://videogamevoters.org/movement Thank you. -- Video Game Voters Network

  • How to check command line requests routed thru TOR?

    - by Chris
    I think I have virtualbox set up so that all traffic originating from the guest OS is routed through TOR. TOR is only installed on the host OS and the web browsers on the guest OS all report TOR IP's in Europe when I test with seemyip.com. The host OS shows my real IP when going to the same sites. But I initiate a lot of requests from the Linux command line and I haven't been able to confirm to my satisfaction that these are routing through TOR, though I have no reason to think they do not. When I use this command I get no output from the guest OS, but my real IP from the host OS: dig myip.opendns.com @resolver1.opendns.com +short This bash file gives no output from either OS: #!/bin/bash echo Your external IP Address is: wget http://Www.whatismyip.com -O - -o /dev/null | grep '<TITLE>' | sed -r 's/<TITLE>WhatIsMyIP\.com \- //g' | sed -r 's/<\/TITLE>//g' exit 0 Suggestions?

  • Effective way to check if an Entity/Player enters a region/trigger

    - by Chris
    I was wondering how multiplayer games detect if you enter a special region. Let's assume there is a huge map that is so big that simply checking it would become a huge performance issue. I've seen bukkit (a modding API for Minecraft servers) firing an Event on every single move. I don't think that larger games do the same because even if you have only a few coordinates you are interested in, you have to loop through a few trigger zone to see if the player is inside your region - for every player. This seems like an extremely CPU-intense operation to me even though I've never developed something like that. Is there a special algorithm that is used by larger games to accomplish this? The only thing I could imagine is to split up the world into multiple parts and to register the event not on the movement itself but on all the parts that are covered by your area and only check for areas that are registered in the current part. And another thing I would like to know: How could you detect when someone must have entered a trigger but you never saw him directly in it since his client only sent you an move packet shortly before entering and after leaving the trigger area. Drawing a line and calculate all colliding parts seems rather CPU intensive if you have to perform it every time.

  • Game Trees Conceptual Question

    - by Chris Corbin
    I am struggling to conceptually understand a question in a programming assignment for an algorithms class. The problem is dealing with a fictitious 2 player game, named Easy. The rules of the game are simple; each player may chose one of 4 integers {0-3} after which that integer is not available for the other player. The catch is, a player picks {0} it means they quit. The objective is for Player 1 to get {1} and Player 2 to get {2}, in which case they may win, however if both or neither succeed, then the game ends in a draw. I have been asked to draw the game tree for Easy, showing all nodes, which they explained as 4! = 24. Labeling the edges, which represent moves (selecting a number) and the leaves with who won (1 means Player 1 won, -1 means Player 2 won, and 0 means a tie). I have drawn out a game tree, which I believe is correct, however I am not 100% certain hence I am asking the question. My game tree only has 16 leaves. I am thinking that when a player picks {0}, and then quits, the game tree stops there? I don't see how it is possible to get to 24 leaves? Any help would be greatly appreciate, and if you need more information I would be happy to provide it. Thanks

  • Web.NET: A Brief Retrospective

    - by Chris Massey
    It’s been several weeks since I had the pleasure of visiting Milan, and joining 150 enthusiastic web developers for a day of server-side frameworks and JavaScript. Lucky for me, I keep good notes. Overall the day went smoothly, with some solid logistics and very attentiveorganizerss, and an impressively diverse audience drawn by the fact that the event was ambitiously run in English. This was great in that it drew a truly pan-European audience (11 countries were represented on the day, and at least 1 visa had to be procured to get someone there!) It was trouble because, in some cases, it pushed speakers outside their comfort zone. Thankfully, despite a slightly rocky start, every session I attended was very well presented, and the consensus on the day was that the speakers were excellent. While I felt that a lot of the speakers had more that they wanted to cover, the topics were well-chosen, every room constantly had a stack of people in it, and all the sessions were pleasingly focused on code & demos. For all that the language barriers occasionally made networking a little challenging,organizerss Simone & Ugo nailed the logistics. Registration was slick, lunch was plentiful, and session management was great. The very generous Rui was kind enough to showcase a short video about Glimpse in his session, which seemed to go down well (Although the audio in the rooms was a little under-powered). Because I think you might need a mid-week chuckle, here are some out-takes.: And lets not forget the Hackathon. The idea was what having just learned about a stack of interesting technologies, attendees could spend an evening (fuelled by pizza and some good Github beer) hacking something together using them. Unfortunately, after a (great)10-hour day, and in many cases facing international travel in the morning, many of the attendees headed straight for their hotel rooms. This idea could work so beautifully, and I’m excited to see how it pans out in 2013. On top of the slick sessions, getting to finally meet Ugo and Simone in the flesh as a pleasure, as was the serendipitous introduction to the most excellent Rui. They’re all fantastic guys who are passionate about the web, and I’m looking forward to finding opportunities to work with them. Simone & Ugo put on a great event, and I’m excited to see what they do next year.
