• Sitemap structure for network of subdomains

  - by HaCos

  I am working on a project that's a network of 2 domains (domain.gr & domain.com.cy) of subdomains similar to Hubpages [each user gets a profile under a different subdomain & there is a personal blog for that user as well] and I think there is something wrong with our sitemap submission. Sometimes it takes weeks in order a new profiles to get indexed. We make use of one Webmasters account in order to manage all network and we don't want to create different accounts for each subdomain since there are more than 1000 already. According to this post http://goo.gl/KjMCjN, I end up on a structure of 5 sitemaps with the following structure : 1st sitemap will be for indexing the others. 2nd sitemap for all users profile under the domain.gr 3nd sitemap for all users profile under the domain.com.cy 4th sitemap for all posts under the *.domain.gr - news sitemap http://goo.gl/8A8S9f 5th sitemap for all posts under the *.domain.com.cy - news sitemap again Now my questions: Should we create news sitemaps or just list all post in 2nd & 3rd sitemap? Does links ordering has anything to do? Eg: Most recent user created be first in sitemap or doesn't make any different and we just need to make sure that lastmod date is correct? Does anyone guess how Hubpages submit their sitemap in Webmasters so maybe we could follow there way? Any alternative or better way to index this kind of schema? PS: Our network is multi language - Greek & English are available. We make use of hreflang tags on the head of each page to separate country target of each version.

• Success Quote: A Hybrid Approach for Success

  - by Lauren Clark

  We recently received this quote from a project that successfully used OUM: “On our project, we applied a combination of the Oracle Unified Method (OUM) and the client's methodology. The project was organized by OUM's phases and a subset of OUM's processes, tasks, and templates. Using a hybrid of the two methods resulted in an implementation approach that was optimized for the client-specific requirements for this project." This hybrid approach is an excellent example of using OUM in the flexible and scalable manner in which it was intended. The project team was able to scale OUM to be fit-for-purpose for their given situation. It's great to see how merging what was needed out of OUM with the client’s methodology resulted in an implementation approach that more closely aligned to the business needs. Successfully scaling OUM is dependent on the needs of the particular project and/or engagement. The key is to use no more than is necessary to satisfy the requirements of the implementation and appropriately address risks. For more information, check out the "Tailoring OUM for Your Project" page, which can be accessed by first clicking on the "OUM should be scaled to fit your implementation" link on the OUM homepage and then drilling into the link on the subsequent page. Have you used OUM in conjunction with a partner or customer methodology? Please share your experiences with us.

• Will adding top level directories with similar structure to existing directories change the SEO of my site?

  - by Russell Sims

  I've been pointed this way for SEO related questions and this one has had me pondering for a little while now. I'm recreating a site's structure. The website's content is generated through several feeds and unless I want to place each and every - of the 10,000 odd - venues into their own category manually, I can't avoid categorising each item by using its address. The current the structure looks like this Homepage > region > county > city/town > venue page and the URL looks like domain/region/county/city/venue/ I'm relatively happy to use this structure as it's not too convoluted. However we also promote deals and we also group the venues into their respective franchise, so that leads to URLs such as: domain/groups AND domain/deals My question is: how would the directory structure look with these new additions? Would I have a URL that looks like domain/deals/region/county/city/venue or domain/group/region/county/city/venue and just put a 301 or a canonical link tag on the page to prevent the duplicate pages competing with each other? Am I just worrying about it needlessly and perhaps link straight from domain/deals to the venue page URL domain/region/county/city/venue, this bothers me a bit though as the deals and groups will not be in the breadcrumbs.

• Wiimote accelerometer input on Windows? (in 2013 - Glovepie alternative?)

  - by user568458

  There were a few options for getting accelerometer input into Windows using a Nintendo Wiimote. As of mid 2013, these projects seem to be dead, corrupted with malware, or both. Are there any tools out there that can do this that are still available (and not full of malware)? Quick roundup of the options that used to exist, or that still exist but aren't suitable: Glovepie, which used to be the most recommended option, appears to be dead: it's own website hacked, its creator's googlepages page full of strange stuff that sounds like hacker-humour about the end of the world... (I'd rather not link to them, very dubious stuff...), and lots of forum threads asking if it's a dead project with comments along the lines of "I heard that the author intends to return to it" dated 2011... Wiiuse seems to be dead: its sourceforge page simply says "Error.", its own website has turned into a squatter page. There apparently was an extension for Autohotkey that allowed Wiimote input, but I've seen warnings that this too is now full of malware (see final commentin above link) Everything else I can find about using Wiimotes as input on Windows - for example, Johnny Lee Cheng's work - seems to be exclusively about using infrared or sensor bar, or tied to a specific purpose (e.g. FPS gaming). My main interest is in the accelerometer, and buttons if possible (although something that supports the IR stuff too would be ideal). Is there anything that works for getting Wiimote accelerometer input into Windows that is reliable and not a malware-fest? If anyone's interested in "Why?", it's to use the Wiimote as an audio / midi controller: to use movement, pitch, roll etc to modulate lots of different sound variables at once with one hand. Wiimotes are great for this, and Glovepie used to be the standard way to make this work (e.g. see for example this tutorial, and this one, ignore the unrelated video; I've also seen musicians using wiimote/glovepie setups at gigs, creating some really unique sounds). As of 2013, however, Glovepie seems to be a dead and thoroughly hacked project, sadly. Is there anything else? With or without MotionPlus is fine (with would be better). If anyone knows of any worthy alternatives to Wiimotes in terms of price and quality that can be made to work with a PC, that would also be great: but in my research I coulnd't find any (here's a link to someone reaching the same conclusion). found some potentially relevant stuff here, not had time to test any of it yet though - http://stackoverflow.com/questions/2984450/using-accelerometer-in-wiimote-for-physics-practicals

• DIY Carbonator Creates Pop Rocks Like Fizzy Fruit [Science]

  - by Jason Fitzpatrick

  If you’ve ever sat around wishing that scientists would stop wasting time trying to solve pressing global problems and instead genetically engineer a bizarre but delicious hybrid of Pop Rocks candy and wholesome fruit, this mad scientist experiment is for you. Over at Evil Mad Scientist Laboratories they share a really fun weekend project. Contributor Rich Faulhaber was looking for a way to make eating fruit extra fun and science-infused for his kids. His solution? Build a homemade carbon dioxide injector that infuses fruit with carbonation. Having trouble imagining that? Envision a bowl of strawberries where every strawberry burst into a crazy flurry of strawberry flavor and champagne bubbles every time you bit into it. Fizzy fruit! Hit up the link below to see how he took pretty common parts: a C02 tank from a paint ball gun, a water filter canister from the hardware store, and other cheap and readily available parts (with the exception of the gas regulator which he suggests you shop garage sales and surplus stores to find a deal on), and combined them together to create a C02 fruit infuser. Hit up the link below to read more about his setup and the procedure he uses to infuse fruit with carbonation.

• General questions regarding open-source licensing

  - by ndg

  I'm looking to release an open-source iOS software project but I'm very new to the licensing side of the things. While I'm aware that the majority of answers here will not lawyers, I'd appreciate it if anyone could steer me in the right direction. With the exception of the following requirements I'm happy for developers to largely do whatever they want with the projects source code. I'm not interested in any copyleft licensing schemes, and while I'd like to encourage attribution in derivative works it is not required. As such, my requirements are as follows: Original source can be distributed and re-distributed (verbatim) both commercially and non-commercially as long as the original copyright information, website link and license is maintained. I wish to retain rights to any of the multi-media distributed as part of the project (sound effects, graphics, logo marks, etc). Such assets will be included to allow other developers to easily execute the project, but cannot be re-distributed in any manner. I wish to retain rights to the applications name and branding. Futher to selecting an applicable license, I have the following questions: The project makes use of a number of third-party libraries (all licensed under variants of the MIT license). I've included individual licenses within the source (and application) and believe I've met all requirements expressed in these licenses, but is there anything else that needs to be done before distributing them as part of my open-source project? Also included in my project is a single proprietary, close-sourced library that's used to power a small part of the application. I'm obviously unable to include this in the source release, but what's the best way of handling this? Should I simply weak-link the project and exclude it entirely from the Git project?

• App_offline.htm and SharePoint and wholly contained images&hellip;

  - by Shawn Cicoria

  The question came up today if we could use an “app_offline.htm” file along with HTML in that file that would reference images. First, I wasn’t 100% sure if the app_offline.htm would work, but it sure did.  Since it’s just the Asp.net hosting process that detects the file, it circumvents loading any HttpApplications (SharePoint) beyond just serving up the HTML content. The second question was about having something more than text, specifically <img> tags.  So, since the HttpHandlers are taking all requests for all resources through the Asp.net pipeline, as soon as the app_offline.htm file is there, nothing else will get served from within that web application.    Sure, we could host the file (images) outside the web app, but what fun would that be? So, I found this link on using an image in app_offline.htm http://pbodev.wordpress.com/2009/12/20/app_offline-htm-with-an-image-yes-we-can/ Turns out, the src tag (in fact many tags) can take a stream of data represented by a mime type and base64 encoding inline – such as: <img style="height:515px;width:700px;border-width:0px;" src="data:image/jpeg;base64,/9j/4AAQSkZJRgA   One of the problems we had was the image was too large; so, sliced up the image, but ended up with spaces between each of the slices.  Low and behold, it works with CSS as well.   <style type="text/css"> .Slice_1_jpg { position: absolute; left:0px; top:0px; width:1011px; height:148px; background: url("data:image/jpeg;base64,/9j/4AAQSkZ   And the body is as follows: <body> <div class="Slice_1_jpg"> </div>   For this, I wrote a little Asp.Net site that, using a file upload control, will generate the necessary contents of what needs to go in the “data” value for the stream.  A link to the code is here: http://cicoria.com/downloads/CreateBase64OfImage.zip

• Is this possible?

  - by PythonNewbie2

  Hello, I'm exploring some technologies and JSP with JSF 2.0 and Primefaces seems really cool. I'm new to all of these, but I'm a fast learner. I wondering if I can create the web app I want withh JSP/JSF/Primefaces or should I be looking to different technologies? If I should, which ones do you recommend? Here's a basic description of the app: Users log in with their username and password (maybe I can somehow incorporate google OPENID)? With a really nice UI, they will be presented a large list of questions specific to a certain category, for example, JSP. When they click on any of these questions, a little input opens up below it to allow the user to put in a link. If the link they enter has the same question on that webpage the URL points to, they will be awarded one point. This question then disappears and gets added to a different page that has a list of all correctly linked questions. On the right side of the screen, there will be a leaderboard with the usernames of the people with the top ten points. Is this possible with JSP/JSF/Primefaces, or should I be looking elsewhere for a different web technology? The idea is relatively simple - to be able to compile links to external websites for specific questions. I know I can build the UI easily with Primefaces. What I'm not sure is if JSP/JSF gives the ability to parse HTML at a certain URL to see if it contains words. I can do this with python easily by using urllib. Any help would be appreciated!!! What would be more helpful than a "Yes" or "No" answer would be links to where I can see sample code of external HTML parsing. Your input is truly appreciated! Thanks!

• TFS2010 Build Controllers

  - by Kabir Rao

  As I know, In TFS2010, One Build Controller serves One Project Collection. And, ideally one build server should have One build controller into it. However, as per the link below- http://marknic.com/2010/05/14/MultipleTFS2010BuildControllersOnASingleBuildBox.aspx we can install mutiple build controller in a single build box. Can two or more build controller can run at a same time. Because the link suggests that, we need to switch between controllers .... Is it that, we can use one controller at a time.

• Why C# does not support multiple inheritance?

  - by Jalpesh P. Vadgama

  Yesterday, One of my friend Dharmendra ask me that why C# does not support multiple inheritance. This is question most of the people ask every time. So I thought it will be good to write a blog post about it. So why it does not support multiple inheritance? I tried to dig into the problem and I have found the some of good links from C# team from Microsoft for why it’s not supported in it. Following is a link for it. http://blogs.msdn.com/b/csharpfaq/archive/2004/03/07/85562.aspx Also, I was giving some of the example to my friend Dharmendra where multiple inheritance can be a problem.The problem is called the diamond problem. Let me explain a bit. If you have class that is inherited from the more then one classes and If two classes have same signature function then for child class object, It is impossible to call specific parent class method. Here is the link that explains more about diamond problem. http://en.wikipedia.org/wiki/Diamond_problem Now of some of people could ask me then why its supporting same implementation with the interfaces. But for interface you can call that method explicitly that this is the method for the first interface and this the method for second interface. This is not possible with multiple inheritance. Following is a example how we can implement the multiple interface to a class and call the explicit method for particular interface. Multiple Inheritance in C# That’s it. Hope you like it. Stay tuned for more update..Till then happy programming.

• Anti-spam measures for websites

  - by acidzombie24

  What are anti-spam measure I should consider before launching my user content website? Some things I have considered: Silent JavaScript based CAPTCHA on the register page (I do not have an implementation) Validate emails by forcing a confirmation link/number Allow X amount of comments per 10 minutes and Y per 2 hours (I am considering excited first time users who want to experience the site) Disallow link until user is trusted (I am not sure how a user will become trusted) Run all comments, messages, etc. through a spam filter. Check to see if messages are duplicate or similar (I may not bother with this. I'd like the system to be strong without this) I also timestamp everything which I then can retrieve as a long on my administrator page. What other measures can I take or consider?

• Why does Ubuntu gets stuck on the loading screen?

  - by mohit

  I've been experiencing many problem lately since I fresh installed Ubuntu 12.04 LTS on my SONY VAIO VPCEH with Windows 7 previously installed. Sometimes when I try to boot Ubuntu, it gets stuck at loading screen. There seems to be some problem with driver (as far I can judge). Following is the log generated, when I press Esc during the boot (before the problem occurs): ... * Stopping System V initialization compatibility [ok] * Starting System V runlevel compatibility [ok] * Starting crash report submission daemon [ok] * Starting automatic crash report generation [ok] ... ... * Starting LightDM Display Manager [ok] Nothing works after that, no Esc, etc, except restart. Also I've observed the following: Inactivity of Hard-drive (Led doesn't glows). Flashing, or blinking, of Caps-lock and Scroll-lock On restart, Ubuntu seem to load successfully. However, the loading screen has somewhat basic graphics. This problem started after I installed Additional drivers: NVIDIA accelerated graphics driver Also, most of the times Ubuntu loads without any problem. However, it is annoying to restart everytime it fails. So my question is: Why this happens and what is the solution?

• Ethernet switch not working

  - by Froskoy

  I've just tried using two different ethernet switches on my network to replace an 8-port Netgear gigabit ethernet switch, which works fine, but doesn't have enough ports for what I need. Computers are connected to a TP-Link TD-8840T router via a switch. They use DHCP for IP address assignment. One switch is a TigerSwitch 6924M, which I'd expect to be difficult to set up, since it is second hand and has an advanced configuration menu, which I can't access without a serial port. However, the second switch that I tried is a new TP-Link TL-SF024, which doesn't appear to have any configuration options, so that can't be the problem. When I say "not working," I mean that although they display that they are connected to a network, they cannot access the internet. For example commands like "ping -c10 google.co.uk" come up with 100% packet loss. What could be causing the problem and how do I fix it?

• How to solve 404 for static files with Django and Nginx?

  - by Lucio

  I setup a Trusty VM with Django + Nginx (other stuffs too). The server is working, I get the "Welcome to Django" page. But when I enter to servername/admin it loads the HTML page but fails to load the static content. And the admin page have this links to static content: <link rel="stylesheet" type="text/css" href="/static/admin/css/base.css" /> <link rel="stylesheet" type="text/css" href="/static/admin/css/login.css" /> Both of the CSS files give me 404, as the Nginx log shows: 192.168.56.1 - - [05/Jun/2014:12:04:09 -0300] "GET /admin HTTP/1.1" 301 5 "-" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:29.0) Gecko/20100101 Firefox/29.0" 192.168.56.1 - - [05/Jun/2014:12:04:09 -0300] "GET /admin/ HTTP/1.1" 200 833 "-" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:29.0) Gecko/20100101 Firefox/29.0" 192.168.56.1 - - [05/Jun/2014:12:04:10 -0300] "GET /static/admin/css/base.css HTTP/1.1" 404 142 "http://ubuntu-server/admin/" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:29.0) Gecko/20100101 Firefox/29.0" 192.168.56.1 - - [05/Jun/2014:12:04:10 -0300] "GET /static/admin/css/login.css HTTP/1.1" 404 142 "http://ubuntu-server/admin/" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:29.0) Gecko/20100101 Firefox/29.0" I think that the error is on my nginx.conf file, but do not know how to solve it.

  What's the correct syntax to link to a CSS file in the same directory as a Greasemonkey JavaScript? I've tried the following but it doesn't work: var cssNode = document.createElement('link'); cssNode.type = 'text/css'; cssNode.rel = 'stylesheet'; cssNode.href = 'example.css'; cssNode.media = 'screen'; cssNode.title = 'dynamicLoadedSheet'; document.getElementsByTagName("head")[0].appendChild(cssNode); If I can get this to work, it would be a lot easier than encasing CSS changes in JavaScript.

• VS 11 Beta merge tool is awesome, except for resovling conflicts

  - by deadlydog

  If you've downloaded the new VS 11 Beta and done any merging, then you've probably seen the new diff and merge tools built into VS 11.  They are awesome, and by far a vast improvement over the ones included in VS 2010.  There is one problem with the merge tool though, and in my opinion it is huge.Basically the problem with the new VS 11 Beta merge tool is that when you are resolving conflicts after performing a merge, you cannot tell what changes were made in each file where the code is conflicting.  Was the conflicting code added, deleted, or modified in the source and target branches?  I don't know (without explicitly opening up the history of both the source and target files), and the merge tool doesn't tell me.  In my opinion this is a huge fail on the part of the designers/developers of the merge tool, as it actually forces me to either spend an extra minute for every conflict to view the source and target file history, or to go back to use the merge tool in VS 2010 to properly assess which changes I should take.I submitted this as a bug to Microsoft, but they say that this is intentional by design. WHAT?! So they purposely crippled their tool in order to make it pretty and keep the look consistent with the new diff tool?  That's like purposely putting a little hole in the bottom of your cup for design reasons to make it look cool.  Sure, the cup looks cool, but I'm not going to use it if it leaks all over the place and doesn't do the job that it is intended for. Bah! but I digress.Because this bug is apparently a feature, they asked me to open up a "feature request" to have the problem fixed. Please go vote up both my bug submission and the feature request so that this tool will actually be useful by the time the final VS 11 product is released.

However reply does not go to the requesting dhcrelay external IP(192.168.0.81). Instead, it goes to the internal interface IP of machine running dhcrelay. And I think because of this remote machine running dhcrelay or the dhcrealy itself discarding packet.

But this does not help ) Regards, -- Oguz YILMAZ UPDATE: The first problem is found. I have configured dhcrelay only on listening internel interface. It seems (of course) is should also listen to external interface for replies. It appears it is not important where the packet destined to. dhrelay will forward it to internal net. HOWEVER, I have deleted route on dhcpd server to reach 172.16.17.x subnet. It again tries to send reply to 172.16.17.81. Because it does not know the route it send it from default gateway to the internet. eth0: IP (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto: UDP (17), length: 328) 192.168.1.2.67 > 172.16.17.81.67: BOOTP/DHCP, Reply, length: 300, hops:1, xid:0x32830125, secs:3, flags: [none] (0x0000) eth0: Your IP: 172.16.17.11 eth0: Gateway IP: 172.16.17.81 eth0: Client Ethernet Address: 00:1e:68:06:eb:37 [|bootp] How can I force dhcpd to force to send replies to requesting IP? Because, it is not much meaningful to add routes to subnet we distribute IP for. Internet - dhcpd - 192.168.0.1 - SOMENET - 192.168.0.81 - dhcrelay - 172.16.17.0/24 192.168.0.1 has no route for 172.16.17.0 and has no interface directly attached to that net.

• What to choose for a multilingual site with support for Markdown and commenting

  - by Kent

  I want to publish articles at a multilingual site. I want to be able to write an article in two languages and have them available on separate URLs: thesite.foo/english-breakfast thesite.com/engelsk-frukost If the users web browser is set to English I'd like to show a small notice at the top of the Swedish version with a link to the English one. The link should have an appropriate rel attribute for a translation (search for hreflang at http://diveintohtml5.org/semantics.html). There should be a way to list all articles belonging to these sets: Swedish only, English only, Swedish versions + English only, English versions + Swedish only. I'd like to publish these as four RSS-feeds. And I would like to have two versions of the main site, one in Swedish (showing Swedish versions + English only) and one in English (showing English versions). I shall be able to write the articles using Markdown, as that is the formatting language I find most convenient. There should be a way for users to comment. And some kind of way for me to protect myself against comment spam. I am leaning towards learning Drupal. I suspect I'll have to code this behavior myself as a module. To be frank I'd rather work with Java. Is Drupal the way to go? Or is there something more suitable for this project?

• Different file locations for http v https on IIS?

  - by Jeremy Morgan

  We have a server running IIS and have some folders running under https, but most are open. The problem I'm having is when someone is directed from a page in the secure section of the site, the relative link brings up https. For example: link to /pictures goes to http://www.mysite.com/pictures But if someone is on a secured part of the site https://www.mysite.com/shoppingcart And then clicks back to /pictures, they get https://www.mysite.com/pictures so the pictures directory is shown under https. My problem is, they get a 404 not found message when this happens. I could not find anything in the settings that would indicate that secured connections are pulling files from anywhere different than non-secured. If I type http or https on the main page of the site both come up fine. But if I try to add the https:// in a folder level, I get a 404. Any ideas why this might be happening?

• lxc containers fail to autoboot in 14.04 trusty using 'lxc.start.auto = 1'

  - by user273046

  In trusty 14.04 containers fail to autoboot despite all settings being set as 14.04 requires. They show all as STOPPED I have correctly configured 2 LXC containers: calypso encelado They run perfectly if I run sudo lxc-autostart then sudo lxc-ls --fancy results in: ubuntu@saturn:/etc/init$ sudo lxc-ls --fancy NAME STATE IPV4 IPV6 AUTOSTART calypso RUNNING 192.168.1.161 - YES encelado RUNNING 192.168.1.162 - YES The problem is trying to run them at boot. I have at: /var/lib/lxc/calypso/config: # Template used to create this container: /usr/share/lxc/templates/lxc-download # Parameters passed to the template: # For additional config options, please look at lxc.conf(5) # Distribution configuration lxc.include = /usr/share/lxc/config/ubuntu.common.conf lxc.arch = x86_64 # Container specific configuration lxc.rootfs = /var/lib/lxc/calypso/rootfs lxc.utsname = calypso # Network configuration lxc.network.type = veth lxc.network.flags = up #lxc.network.link = lxcbr0 lxc.network.link = br0 lxc.network.hwaddr = 00:16:3e:64:0b:6e # Assegnazione IP Address lxc.network.ipv4 = 192.168.1.161/24 lxc.network.ipv4.gateway = 192.168.1.1 # Autostart lxc.start.auto = 1 lxc.start.delay = 5 lxc.start.order = 100 and I have LXC_AUTO="false" as required inside /etc/default/lxc: LXC_AUTO="false" USE_LXC_BRIDGE="false" # overridden in lxc-net [ -f /etc/default/lxc-net ] && . /etc/default/lxc-net LXC_SHUTDOWN_TIMEOUT=120 Any idea on why the containers don't start at boot? At reboot they are always in the STOPPED state: ubuntu@saturn:~$ sudo lxc-ls --fancy NAME STATE IPV4 IPV6 AUTOSTART calypso STOPPED - - YES encelado STOPPED - - YES and then again they can be started manually, using sudo lxc-autostart

• beginner - best way to do a 'Confirm' page? [closed]

  - by W_P

  I am a beginning web app developer, wondering about the best way to implement a "Confirm Page" upon form submission. I have heard that it's best for the script that a form POSTs to to be implemented by handling the POST data and then redirecting to another page, so the user isn't directly viewing the page that was POSTed to. My question is about the best way to implement a "Confirm before data save" page. Do I Have my form POST to a script, which marshals the data, puts in a GET, and redirects to the confirm page, which unmarshals and displays the data in another form, where the user can then either confirm (which causes another POST to a script that actually saves the data) or deny (which causes the user to be redirected back to the original form, with their input added)? Have my form POST directly to the confirm page, which is displayed to the user and then, like #1, gives the user the option to confirm or deny? Have my form GET the confirm page, which then does the expected behavior? I feel like there is a common-sense answer to this question that I am just not getting.
