  • node.js server not running

    - by CMDadabo
    I am trying to learn node.js, but I'm having trouble getting the simple server to run on localhost:8888. Here is the code for server.js: var http = require("http"); http.createServer(function(request, response) { response.writeHead(200, {"Content-Type": "text/plain"}); response.write("Hello World"); response.end(); }).listen(8888); server.js runs without errors, and trying netstat -an | grep 8888 from terminal returns tcp4 0 0 *.8888 *.* LISTEN However, when I go to localhost:8888 in a browser, it says that it cannot be found. I've looked at all the related questions, and nothing has worked so far. I've tried different ports, etc. I know that my router blocks incoming traffic on port 8888, but shouldn't that not matter if I'm trying to access it locally? I've run tomcat servers on this port before, for example. Thanks so much for your help! node.js version: v0.6.15 OS: Mac OS 10.6.8

  • Working Qt controls in a 3d environment

    - by Jay
    I need some advice from a Qt expert. The background: I have a 3D engine (ogre3d) working in concert with Qt. The 3D Content is displayed in a widget (using a custom OS window in the client area). I'm able to overlay arbitrary Qt widgets onto the 3d world using the widget render() method and a shared bitmap. This makes a great "heads up display". I can use the standard Qt style sheets and animation using this technique. My goal I'd like to go a step further and allow the user to move these rendered widgets using the mouse. I'd like some advice on the best way to implement this. Possible solutions: The widgets in the HUD are not part of the inheritance chain. I render them manually. They don't get events though. I could add them to the inheritance chain so they get events in the usual way. Then I would need to change them to render to my shared bitmap instead of to the operating system. I looked at this once but couldn't find enough information to implement it. Capture mouse events in the 3D display widget and EMIT them to child controls. I basically create my own event handling chain. Any suggestions on how to implement this? I'm also considering switching to Qt5. I'm not sure how that might affect this decision.

  • Windows file Sync

    - by Deane Venske
    So I have a big problem at the moment. Trying to find a reliable solution for syncing 2 windows IIS servers. I need to keep the web content imaged on both. Now I have been trying to use Rsync to this point, but unfortunately file permission errors are a nightmare to manage this way. I'm testing out dropbox, but the performance sucks. I'm more familiar with Linux stuff and I've used Rsync in the past but isn't there a native windows solution that will work?

  • Best Wiki Software For Product Support

    - by Zapnologica
    Good day, I am looking for a wiki system which we are going to use at work for a form of product support. We manufacture multiple devices and now i want to make a wiki which contains all sorts of relevant and helpful information on that product which the users can look at before trying to contact us for support? Now immediately the 1st option that comes to my mind in Media wiki but I dont just want to jump on the band wagon. I thought I would ask around first. It should preferable be free. But obviously if its really worth paying for then thats not the end of the world. And the uploading of content and media is not of much importance as the end users will simply be reading the information which the company has published. Another nice to have but is not critical is if it where to run on asp.net as we have Microsoft server running anyway.

  • Appcache and jquery mobile on a CMS powered site?

    - by user793011
    Has anyone used the cache manifest to make a CMS site work offline? I've made a demo with static html files which seems to work fine, so I'm assuming it wouldn't be too hard to achieve the same thing with a CMS. The way that you tell browsers that files have changed (and so need to be downloaded again) is by adding a comment to the cache manifest file so its byte size changes. I'm not quite sure how to do this with a CMS, but maybe some sort of server cron could run periodically? Personally I'm more interested in having a site that works offline rather than achieving ideal performance, so if the file was modified every hour rather than when content actually changed that would be fine for me. If anyone has used appcache with a CMS, has anyone done so with jquery mobile at the same time? What I'm after is a fully native feel to a site that's accessible offline, in other words I want to mimic a native App. My static demo does this perfectly with jquery mobile, so again I would have thought this would be achievable in a CMS.

  • Squid gives always tcp_miss reverse proxy

    - by JaakL
    I added installed latest squid3 in front of apache as reverse proxy. The problem is that it gives always tcp_miss, in fact I have not yet found a single TCP_HIT message in the log file, and most of the content is static. Relevant config values for cache_dir and refresh_pattern are default ones, directory /var/spool/squid3 exists and has some files/folders. I have 100+G free storage, but reconfigure gives warning "WARNING cache_mem is larger than total disk cache space!", which does not make any sense to me. I have googled a lot and seen with similar problems, but none of them has helped.

  • SEO Blog Indexing : Dot Wordpress Versus a Registered Domain?

    - by rumspringa00
    I've used Wordpress for a few of my client's sites, mostly small businesses and ecommerce sites. I have found through Google Analytics as well as the All in One Webmaster plugin that when it comes to social media, using Wordpress is a surefire way of getting your site indexed by Google and occasionally Bing and Yahoo. Since I am a heavy WP user, I'd like to contribute by registering a dot Wordpress domain for my portfolio. When using a WP installation concurrently with a WP domain, e.g. myportfolio.wordpress.com, will the site be more or less likely to be indexed rather a generic myportfolio.com domain? I've seen mixed opinions where people seem to favor a WP domain for URL output where others say that it's a moot point, and that Google will not favor a WP domain over a dot com domain as long as your meta tags are updated and content is keyword optimized. I tend to disagree and believe a WP domian would more likely be indexed and output more URLs over an individual, laconic domain like myportfolio.com. Am I wrong? Thanks in advance!

  • Apache HTTP Not Working When SSL Enabled

    - by dominic7il
    I've got a very bizarre problem in that after enabling SSL support in Apache I'm only able to access my site via SSL and not through http as well. I can confirm that Apache is definitely listening on both ports 80 and 443 (accdording to netstat). Additionally the Apache access logs are showing the requests - it's just that going in through http results in a timeout and I'm never actually able to reach the content. Like I said going through https works. Here is my httpd.conf: http://pastebin.com/kG2dPjJ2 and here is my httpd-ssl.conf: http://pastebin.com/thqvjgGJ Can anyone spot any issues with those configurations? or Have any suggestion at all? I've searched and searched but there appear to be very few people who have experienced the same. Also worth mentioning that I did a comparision between those configurations and those of a working set up and I couldn't spot anything.

  • What kind of projects are suited as a portfolio? [on hold]

    - by Asyx
    I was thinking about finishing up some hobby projects I used myself or am planing to use myself but I'm not sure if a future employer might be put off by them. For example, if I decided to create a custom website for an online (gaming, maybe) community instead of using an existing CMS, is it a good idea to provide a link to said community website or should I just put up the CMS and pretend like nobody actually uses it? Also, what about very specific things? I like linguistics and constructing languages. Obviously nobody wants to come up with 1000s of words so people usually use word generators or software to emulate sound shift or software to organise everything and produce dictionaries and such. Would such a project be too specific and too abstract for a portfolio or is the "he did programming work simply for enjoyment and his hobby and not just for money or grades" thing more important? It's quite an abstract hobby and most people don't even know that it's a thing and think the languages you hear in Game of Thrones, Avatar or Star Trek are just gibberish. Explaining such things to people is a pain to begin with especially if said people speak no other language. Would such things throw an employer off or is the content itself completely irrelevant? Thanks. Also, if this is not fitting for the programmers stackexchange, then please, don't close the thread right away but tell me where else to go because I got here though a closed question from stackoverflow. Thanks.

  • SunSpace - a sentimental moment

    - by me
    I just came back from California where I had a little sentimental moment.With the great help from some former Sun colleagues we move the old SunSpace gear into a new data center in Santa Clara.We will re-purpose the hardware as a new development infrastructure to build integrated demos around Oracle WebCenter products, Business Applications and Social Services. now - I could not resist to restart the SunSpace applications and see if it still works. And hey - even though we had to re-IP the entire  stack (sun.com domain is gone) and with some little hacking (thanks to Apache reverse proxy) -  we got it back! Hey Max - now I just need to change your SSO hack to get login working again Hmm - I won't - but it is really nice to see it working again .. and it's time to switch it off and to work  on the next cool things .. Do you know Oracle WebCenter Sites (formely Fatwire)? Its Oracle's Web Experience Management Solution - a pretty cool technology and a very slick User Interface. I specially like the drag&drop functionality which allows non technical users to easily publish content.  Why do I mention it here ?  Because we will use the SunSpace gear to build cool  Oracle WebCenter Sites demos and proof of concepts integration  into Business Applications and Social Services  This is a sneak preview what we are working on. Stay tuned.....

  • What are your most useful textexander (or similar) snippets?

    - by P.Bjorklund
    Textexpander is a program that aims to save you time by auto-replacing snippets of text with the content of your choice, or to quote their Web site: "Save yourself time and effort by typing short abbreviations for frequently-used text and images." So for instance when you type ,h1 it will change it to <h1></h1> with the cursor placed between the <. After some searching I have yet to find a resource/forum-thread/whatnot that discuss the uses of this marvelous program. I am therefor looking for your best snippets or a link to a resource where I can find this. Oh and one thing I can think of right away is sigw, sigp for my work/personal email signature.

  • Can I lvreduce after lvextend without losing the ext4 partition inside it?

    - by DrSAR
    In a botched attempt to move my root partition from one disk to another I have done the following: added new disk partitioned it with parted (part #3 is now almost totally filling the disk) initialized a physical volume $ pvcreate /dev/sdb3 Physical volume "/dev/sdb3" successfully created extended the volume group to include this new physical disk $ vgextend myvg /dev/sdb3 Volume group "myvg" successfully extended extended the logical volume (I think this is where I ballsed it up: I think I should have pvmove'ed stuff to the new pv in that group - can someone confirm?) $ lvextend /dev/mapper/myvg-root /dev/sdb3 I would now like to undo the lvextend and then proceed with the original plan of moving the content of the old physical volume over to the new physical volume. Can I reduce the logical volume (I have not yet touched the ext4 partition that sits in /dev/mapper/myvg-root with something like resizefs) without fear of damaging the ext4 filesystem? If so, how do I tell it to reduce by exactly the right amount? $ lvreduce --by-exactly-the-amount-occupied-by-PV /ev/sdb3 /dev/mapper/myvg-root

  • Question about server usage, big community platform [closed]

    - by Json
    Possible Duplicate: How do you do Load Testing and Capacity Planning for Web Sites I’m working on a community platform writen in PHP, MySQL. I have some questions about the server usage maybe someone can help me out. The community is based on JQuery with many ajax requests to update content. It makes 5 - 10 AJAX(Json, GET, POST) requests every 5 seconds, the requests fetch user data like user notifications and messages by doing mySQL queries. I wonder how a server will handle this when there are for more than 5000 users online. Then it will be 50.000 requests every 5 seconds, what kind of server you need to handle this? Or maybe even more, when there are 15.000 users online, 150.000 requests every 5 seconds. My webserver have the following specs. Xeon Quad 2048MB 5000GB traffic Will it be good enough, and for how many users? Anyone can help me out or know where to find such information, like make a calculation?

  • Allow access only to one website

    - by Alex
    Hey. I'd like to allow access on a computer connected directly to the internet to one website ONLY. The solution of IE's "Content advisor" or firefox's "FoxFilter" isn't good enough because it actually downloads the data and just don't display it. I want to block the traffic before the requests are sent. How is it possible? Thanks. Edit: OS is windows xp. The browser can be firefox, iexplorer, chrome... It doesn't matter. The computer is connected directly to the modem.

  • How do you redirect pages from a subdirectory up one level to the root directory

    - by kezzman11
    I have recently moved all the content on my website from being in the www.mysite.com/shop directory to being in the root directory. This means that now I need to redirect any request to visit a page with the /shop directory back to the same page in the root directory eg. www.mysite.com/shop/categories/washroom to www.mysite.com/categories/washroom This needs to happen with all pages in my site that were previously using the /shop directory. The closest thing to a solution that I have found so far is the following code RedirectMatch ^/shop/.* http://www.mysite.com/ however this redirects all pages back to the homepage instead of to the relevant matching page without the /shop. Can someone please point me in the right direction, or if this has already been answered in here can you please post the link to the answer.

  • Hosting and scaling a Facebook application in the cloud? [closed]

    - by DhruvPathak
    Possible Duplicate: How to find web hosting that meets my requirements? We would be building a Facebook application in Django (Python), but still not sure of where to host it economically, and with a good provision to scale in case the app gets viral. Some details about the app: Would be HTML based like a website,using django as a framework. 100K is the number of expected pageviews in a day, if the app is viral. The users will not generate any media content, only some database data will be generated by them. It would be great if someone with more experience can guide on following points: A) Hosting on Google app engine or Amazon EC2 or some other cloud like RackSpace : Preferable points found in AppEngine were ease of deployment, cost effectiveness and easy scaling. For EC2: Full hold of the virtual machine,Amazon NoSQL and RDMBS database services in case we decide to use them. B) Does backend technology affect monthly cost? eg. would CPU and memory usage difference of Django over , for example , PHP framework like CodeIgnitor really make remarkable difference in running costs. (Here is the article that triggered this thought process : http://journal.dedasys.com/2010/01/12/rough-estimates-of-the-dollar-cost-of-scaling-web-platforms-part-i#comments) C) Does something like Heroku , which provides additional services over Amazon EC2, prove to be better than raw cloud management? It is not that we are trying for premature scaling, we just want to have a good start so that we are ready to handle unpredicted growth and scale.

  • Using mod_rewrite for a Virtual Filesystem vs. Real Filesystem

    - by philtune
    I started working in a department that uses a CMS in which the entire "filesystem" is like this: create a named file or folder - this file is given a unique node (ex. 2345) as well as a default "filename" (ex. /WelcomeToOurProductsPage) and apply a template assign one or more aliases to the file for a URL redirect (ex. /home-page-products - can also be accessed by /home-page-products.aspx) A new Rewrite command is written on the .htaccess file for each and every alias Server accesses either /WelcomeToOurProductsPage or /home-page-products and redirects to something like /template.aspx?tmp=2&node=2345 (here I'm guessing what it does - I only have front-end access for now - but I have enough clues to strongly assume) Node 2345 grabs content stored in a SQL Db and applies it to the template. Note: There are no actual files being created on the filesystem. It's entirely virtual. This is probably a very common thing, but since I have never run across this kind of system before two months ago, I wanted to explain it in case it isn't common. I'm not a fan at all of ASP or closed-sourced systems, so it may be that this is common practice for ASP developers. My question, that has taken far too long to ask, is: what are the benefits of this kind of system, as opposed to creating an actual file hierarchy? Are there any drawbacks to having every single file server call redirected? To having the .htaccess file hold rewrite rules for every single alias?

  • nginx serves broken characters

    - by Andrew123321
    I have nginx 1.2.0-1 on debian 6.0.5. I have an empty file (let's say test.css). I add A and newline, works fine, B and newline, works fine,... D, works fine. I add E and I got three broken characters ("???"). When the file has got more content nginx would usually "cache" it and then output the cached file minus some characters plus some of these broken characters. Do you have any idea how to deal with this? Thank you

  • Why is chrome slashing my HTTPS?

    - by John Isaacks
    In Chrome when I view my page the https in the URL has a red slash through it. When I click it, it says: Your connection to www.example.com is encrypted with 256-bit encryption. However, this page includes other resources which are not secure. ... I am not getting the mixed content warning in IE or FF. Is there a way to get Chrome to tell you exactly what/where is causing the issue? I am having trouble finding what is causing Chrome to throw a hissy fit. I searched my source for any http that does not contained https but am not seeing any. It would be nice if there is an easy way to pinpoint the issue.

  • How and what should I be (unit) testing for in this method?

    - by user460667
    I am relatively new to unit testing and have a query about what/how I should be testing a certain method. For the following (psudo-c#) method I have created (not a real-life example) what would you test for? Initially, my thoughts would be to test the output with variations on the dictionary of form fields, e.g. valid, invalid, missing values. However I also wonder how you would test to make sure the object values have been changed to the correct value and that the correct email message was attempted to be sent (obviously both services could/would be mocked). I hope what I am asking makes sense, I appreciate this is a subjective question and the answers may be 'it depends' ;) public bool ProcessInput(Dictionary<string, string> formFields, ObjService objService, EmailService emailService) { try { // Get my object id int objId; if(!int.TryParse(formField["objId"], out objId) { return false; } // Update my object - would you validate the save against a DB or a mocked inmemory db? var myObj = objService.Find(objId); myObj.Name = formField["objName"]; objService.Save(myObj); // Send an email - how would you test to make sure content, recipient, etc was correct? emailService.SendEmail(formField("email"), "Hello World"); return true; } catch(Exception ex) { return false; } }

  • How to enable Postfix filter on OS X server (Lion) without getting overwritten?

    - by mjbraun
    I have a Postfix after-queue content filter that works fine on stock Ubuntu Postfix install. However, on a OS X Lion Server I'm testing out, I see this "auto-generated" language in the master.cf file: # ==== Begin auto-generated section ======================================== # This section of the master.cf file is auto-generated by the Server Admin # Mail backend plugin whenever mails settings are modified. smtp inet n - n - 1 postscreen smtpd pass - - n - - smtpd -o receive_override_options=no_address_mappings The problem is, to enable the filter the same area of the master.cf file has to be changed to have an entry like this: smtp inet n - - - - smtpd -o content_filter=mytest_filter:dummy So, it looks like the line would be blown away every I make a change in Server Admin. Is there a better place for me to put the call to the filter such that it's persistent? I appreciate any assistance and/or guidance!
