  • Correct permissions for /var/www and wordpress

    - by dpbklyn
    Hello and thank you in advance! I am relatively new to ubuntu, so please excuse the newbie-ness of this question... I have set up a LAMP server (ubuntu server 11.10) and I have access via SSH and to the "it works" page from a web browser from inside my network (via ip address) and from outside using dyndns. I have a couple of projects in development with some outside developers and I want to use this server as a development server for testing and for client approvals. We have some Wordpress projects that sit in subdirectories in /var/www/wordpress1 /var/www/wordpress2, etc. I cannot access these sub directories from a browser in order to set up WP--or (I assume) to see the content on a browser. I get a 403 Forbidden error on my browser. I assume that this is a permissions problem. Can you please tell me the proper settings for the permissions to: 1) Allow the developers and me to read/write. 2) to allow WP set up and do its thing 3) Allow visitors to access the site(s) via the web. I should also mention that the subfolder are actually simlinks to folder on another internal hdd--I don't think this will make a difference, but I thought I should disclose. Since I am a newbie to ubuntu, step-by-step directions are greatly appreciated! Thank you for taking the time! dp total 12 drwxr-xr-x 2 root root 4096 2012-07-12 10:55 . drwxr-xr-x 13 root root 4096 2012-07-11 20:02 .. lrwxrwxrwx 1 root root 43 2012-07-11 20:45 admin_media -> /root/django_src/django/contrib/admin/media -rw-r--r-- 1 root root 177 2012-07-11 17:50 index.html lrwxrwxrwx 1 root root 14 2012-07-11 20:42 media -> /hdd/web/media lrwxrwxrwx 1 root root 18 2012-07-12 10:55 wordpress -> /hdd/web/wordpress Here is the result of using chown -R www-data:www-data /var/www total 12 drwxr-xr-x 2 www-data www-data 4096 2012-07-12 10:55 . drwxr-xr-x 13 root root 4096 2012-07-11 20:02 .. lrwxrwxrwx 1 www-data www-data 43 2012-07-11 20:45 admin_media -> /root/django_src/django/contrib/admin/media -rw-r--r-- 1 www-data www-data 177 2012-07-11 17:50 index.html lrwxrwxrwx 1 www-data www-data 14 2012-07-11 20:42 media -> /hdd/web/media lrwxrwxrwx 1 www-data www-data 18 2012-07-12 10:55 wordpress -> /hdd/web/wordpress I am still unable to access via browser...

  • What's the simplest way to create a page with dynamic elements?

    - by ElendilTheTall
    I'm developing a site, part of which lists training courses with dates and prices. Every year the dates and prices change, which would mean loads of manual code editing to update the pages. What I'd like to do is have a database containing the relevant information, which the course pages then reference, so we can just update the database rather than the HTML. My experience lies in static design - so, what is a simple way to achieve this?

  • Play Framework Plugin for NetBeans IDE

    - by Geertjan
    The start of minimal support for the Play Framework in NetBeans IDE 7.3 Beta would constitute (1) recognizing Play projects, (2) an action to run a Play project, and (3) classpath support. Well, most of that I've created already, as can be seen, e.g., below you can see logical views in the Projects window for Play projects (i.e., I can open all the samples that come with the Play distribution). Right-clicking a Play project lets you run it and, if the embedded browser is selected in the Options window, you can see the result in the IDE. Make a change to your code and refresh the browser, which immediately shows you your changes: What needs to be done, among other things: A wizard for creating new Play projects, i.e., it would use the Play command line to create the application and then open it in the IDE. Integration of everything available on the Play command line. Maybe the logical view, i.e., what is shown in the Projects window, should be changed. Right now, only the folders "app" and "test" are shown there, with everything else accessible in the Files window, as can be seen in the screenshot above. More work on the classpath, i.e., I've hardcoded a few things just to get things to work correctly. Options window extension to register the Play executable, instead of the current hardcoded solution. Scala integrations, i.e., investigate if/how the NetBeans Scala plugin is helpful and, if not, create different/additional solutions. E.g., the HTML templates are partly in Scala, i.e., need to embed Scala support into HTML. Hyperlinking in the "routes" file, as well as special support for the "application.conf" file. Anyone interested, especially if you're a Play fan (a "playboy"?), in joining me in working on this NetBeans plugin? I'll be uploading the sources to a java.net repository soon. It will be here, once it has been made publicly accessible: http://java.net/projects/nbplay/sources/nbplay Kind of cool detail is that the NetBeans plugin is based on Maven, which means that you could use any Maven-supporting IDE to work on this plugin.

I don't have experience in creating websites, I did my college project using jsp,servlet and jdbc. What are the things or technology I need to know before creating website. Is it possible to create a website by one person?

  • Do I need to paste open source license information at the top of my webpage?

    - by Rich
    I'm developing a JavaScript application that uses several open source JavaScript projects. All their licenses have a phrase like "You must give any other recipients of the Work or Derivative Works a copy of this License". Does this mean I need to make a massive HTML comment at the top of my webpage with all the licences of the software that I use? I ask this question because I've never seen the source code of a webpage that does this.

  • Voronoi regions of a (convex) polygon.

    - by Xavura
    I'm looking to add circle-polygon collisions to my Separating Axis Theorem collision detection. The metanet software tutorial (http://www.metanetsoftware.com/technique/tutorialA.html#section3) on SAT, which I discovered in the answer to a question I found when searching, talks about voronoi regions. I'm having trouble finding material on how I would calculate these regions for an arbitrary convex polygon and aleo how I would determine if a point is in one + which. The tutorial does contain source code but it's a .fla and I don't have Flash unfortunately.

  • What ever happened to the Defense Software Reuse System (DSRS)?

    - by emddudley
    I've been reading some papers from the early 90s about a US Department of Defense software reuse initiative called the Defense Software Reuse System (DSRS). The most recent mention of it I could find was in a paper from 2000 - A Survey of Software Reuse Repositories Defense Software Repository System (DSRS) The DSRS is an automated repository for storing and retrieving Reusable Software Assets (RSAs) [14]. The DSRS software now manages inventories of reusable assets at seven software reuse support centers (SRSCs). The DSRS serves as a central collection point for quality RSAs, and facilitates software reuse by offering developers the opportunity to match their requirements with existing software products. DSRS accounts are available for Government employees and contractor personnel currently supporting Government projects... ...The DoD software community is trying to change its software engineering model from its current software cycle to a process-driven, domain-specific, architecture-based, repository-assisted way of constructing software [15]. In this changing environment, the DSRS has the highest potential to become the DoD standard reuse repository because it is the only existing deployed, operational repository with multiple interoperable locations across DoD. Seven DSRS locations support nearly 1,000 users and list nearly 9,000 reusable assets. The DISA DSRS alone lists 3,880 reusable assets and has 400 user accounts... The far-term strategy of the DSRS is to support a virtual repository. These interconnected repositories will provide the ability to locate and share reusable components across domains and among the services. An effective and evolving DSRS is a central requirement to the success of the DoD software reuse initiative. Evolving DoD repository requirements demand that DISA continue to have an operational DSRS site to support testing in an actual repository operation and to support DoD users. The classification process for the DSRS is a basic technology for providing customer support [16]. This process is the first step in making reusable assets available for implementing the functional and technical migration strategies. ... [14] DSRS - Defense Technology for Adaptable, Reliable Systems URL: http://ssed1.ims.disa.mil/srp/dsrspage.html [15] STARS - Software Technology for Adaptable, Reliable Systems URL: http://www.stars.ballston.paramax.com/index.html [16] D. E. Perry and S. S. Popovitch, “Inquire: Predicate-based use and reuse,'' in Proceedings of the 8th Knowledge-Based Software Engineering Conference, pp. 144-151, September 1993. ... Is DSRS dead, and were there any post-mortem reports on it? Are there other more-recent US government initiatives or reports on software reuse?

  • Problem with 'insert_at_cursor' attribute

    - by mivoligo
    I made something, so after clicking a button, some text should appear in the TextView. Part of my code: def on_button1_clicked(self, builer): self.writetest = self.builder.get_object("textview1") self.writetest.insert_at_cursor("something") Unfortunately, when I click the button I get: AttributeError: 'TextView' object has no attribute 'insert_at_cursor' According to GTK Documentation there is such attribute: http://developer.gnome.org/gtk3/stable/GtkTextView.html#GtkTextView-insert-at-cursor I have the same problem with Entry as well, if I change TextView to Entry. But if I use set_text instead of insert_at_cursor in my code, it works.

  • How can I export emacs documents in 13.04?

    - by Whippy
    When I try to export a document from org-mode in emacs, c-X, c-E now results in 'Can't find library org' whereas in 10.04 it opened the export dialog allowing me to produce html, pdf etc. from the source org file. Searching with Google, I found this bug for redhat which looks closely related. The trouble is I don't know how to get hold of the emacs-el package it talks about in ubuntu in order to try its workaround so I'm currently stuck.

  • what would be a good way to implement/render a 2d tiled map for a browser game?

    - by jj_
    I've made this little rpg ruby game I did while learning and now I'd like to make it into a browser game. I've already set up Sinatra framework to serve it, so what I am looking for, before everything else, is a way to represent the game map in browser (location attributes are stored in db). A new map is randomly generated by code for each new game at each game start. For now forget db, and let's say a map (say 100x100 "squares") is stored as a tridimensional array. (x,y, ...) Last "dimension" of array stores who & what is at that map cell: a player, a building, whatever. So all I have to do is render those "squares" or array cells to a 2d tiled map in the browser. The map does not need to refresh or be dynamically fetched as you scroll it, (at least at this stage of development) but, a technology which would allow me to do so in future would be a good reason for choosing it. Things that I thought of: html tables, html5 canvas, some js framework which is designed exactly with this purpose (which I do not know of = please advice). Yes I know about gamequery-js framework, but I've never used it, and I don't know if it's going to slow down everything down to inusability as I'm adding new features (scrolling, ajax). I really don't know of any other alternatives.. maybe there are lighter approaches? Easier or more minimalistic ways ? More targeted js framework which is the right tool for the job? Maybe just some html canvas code, or even simple image maps, or images with absolute positioning will be enough? The thing is I'd like to start simple, and then gradually make it better, so, as I said before, I'd prefer something that will give me room for improvement or is headed toward new web tendencies but which will also give me a bit of gratification in the beginning :) So.. advices are needed! And appreciated! :) Thanks p.s. Flash is excluded because I don't like it.

  • Insert Or update (aka Replace or Upsert)

    - by Davide Mauri
    The topic is really not new but since it’s the second time in few days that I had to explain it different customers, I think it’s worth to make a post out of it. Many times developers would like to insert a new row in a table or, if the row already exists, update it with new data. MySQL has a specific statement for this action, called REPLACE: http://dev.mysql.com/doc/refman/5.0/en/replace.html or the INSERT …. ON DUPLICATE KEY UPDATE option: http://dev.mysql.com/doc/refman/5.0/en/insert-on-duplicate.html With SQL Server you can do the very same using a more standard way, using the MERGE statement, with the support of Row Constructors. Let’s say that you have this table: CREATE TABLE dbo.MyTargetTable (     id INT NOT NULL PRIMARY KEY IDENTITY,     alternate_key VARCHAR(50) UNIQUE,     col_1 INT,     col_2 INT,     col_3 INT,     col_4 INT,     col_5 INT ) GO INSERT [dbo].[MyTargetTable] VALUES ('GUQNH', 10, 100, 1000, 10000, 100000), ('UJAHL', 20, 200, 2000, 20000, 200000), ('YKXVW', 30, 300, 3000, 30000, 300000), ('SXMOJ', 40, 400, 4000, 40000, 400000), ('JTPGM', 50, 500, 5000, 50000, 500000), ('ZITKS', 60, 600, 6000, 60000, 600000), ('GGEYD', 70, 700, 7000, 70000, 700000), ('UFXMS', 80, 800, 8000, 80000, 800000), ('BNGGP', 90, 900, 9000, 90000, 900000), ('AMUKO', 100, 1000, 10000, 100000, 1000000) GO If you want to insert or update a row, you can just do that: MERGE INTO     dbo.MyTargetTable T USING     (SELECT * FROM (VALUES ('ZITKS', 61, 601, 6001, 60001, 600001)) Dummy(alternate_key, col_1, col_2, col_3, col_4, col_5)) S ON     T.alternate_key = S.alternate_key WHEN     NOT MATCHED THEN     INSERT VALUES (alternate_key, col_1, col_2, col_3, col_4, col_5) WHEN     MATCHED AND T.col_1 != S.col_1 THEN     UPDATE SET         T.col_1 = S.col_1,         T.col_2 = S.col_2,         T.col_3 = S.col_3,         T.col_4 = S.col_4,         T.col_5 = S.col_5 ; If you want to insert/update more than one row at once, you can super-charge the idea using Table-Value Parameters, that you can just send from your .NET application. Easy, powerful and effective

How do I create a directory that can archive data in an alphabetical ordering? It also has to be able to sort by letters and other categories. Does anyone have an idea of how I should go about doing this? Thanks!

  • Is there a tool for detecting sites using the same template?

    - by KTB
    I often buy webtemplates online, and when I do so I often look at the demos to get some inspiration on how to use the components. But I would love to look at other sites which have already implemented a full website using this template. So I am looking for a tool which searches sites having a similar HTML as the demos (and therefore are probably implementing the template). I am referring to templates which do not have a static text like "Created with Template FooBar by BarFoo" in the footer.

This is true because it does lend a hand in the advertising of websites and simultaneously it requires some technical understanding - as a minimum familiarity with fundamental HTML. It is sometimes also called SEO copyrighting since most of the practice that are used to egg on sites in search engines pact with text.
