• WordPress bot issues

  - by Paul

  I need to implement a blog into a clients site as he is unhappy with his current basic CMS driven solution. It needs to suit both seo and the current style and as I'm a front end dev/designer and they don't have budget to redevelop - the only solution I can think of is to setup a Wordpress blog and restyle to suit. My only worry about this is the current press reports on WordPress being affected by webbots. I understand the main worry Is if you use an id of admin, but I'm concerned that regardless of this the site could be bombarded with bot requests and cause timeouts! Is this valid? If so is there any way to avoid this issue!? If not can anyone recommend another good SEO friendly blog solution!?

• Robots.txt never downloaded but some blocked URLs in GWT

  - by Zistoloen

  There is something I don't understand in Google Webmaster Tools (GWT) for my Wordpress site. In menu "Blocked URLs", it mention that my robots.txt has never been downloaded but there are some blocked URLs. It's kind of weird and not logical. Am i missing something? User-agent : * Disallow: /*? Disallow: /wp-login.php Disallow: /wp-admin Disallow: /wp-includes Disallow: /wp-content Allow: /wp-content/uploads Disallow: */trackback Disallow: /*/feed Disallow: /*/comments Disallow: /cgi-bin Disallow: /*.php$ Disallow: /*.inc$ Disallow: /*.gz$ Disallow: /*.cgi$ Disallow: /author/* I'm afraid my robots.txt doesn't block several URLs I want to block.

• Is PhotoBucket a viable solution to host a website's photo galleries

  - by Evan Plaice

  I'm currently working with a lot of photographers and will probably be picking up development on a professional photography site soon. With that in mind, and I can't stop thinking about a way I can implement a user-friendly photo gallery hosting solution where the site owner can upload images themselves without any webmaster intervention. Kind of like a CMS for image hosting. The idea is: - The user can log in to PhotoBucket - Upload their gallery - Visit an admin section of the site - Enter the new gallery name to the listing And... Voila, the gallery automagically gets displayed on the website in a clean lightbox-style presentation format (ie, no iframe nonsense). I took a brief look at the API and it looks promising. Is this a viable solution? Bonus points if you have implemented something like this with Photobucket and/or another 3rd-party image hosting site. Note: Purchasing a premium account is expected if necessary. The limitations on free accounts at most image hosting sites are just too restrictive to be useful.

• detecting when you are going to reach your hit limit for Google Analytics free account

  - by crmpicco

  I am a user of a free Google Analytics account and i'm slightly concerned that I may be approaching the 10,000,000 hit (Pageviews, Events etc) per month. Google state in their documentation: These limits apply to the Web Property / Property / Tracking ID. 10 million hits per month per property If you go over this limit, the Google Analytics team might contact you and ask you upgrade to Premium or implement client sampling to reduce the amount of data being sent to Google Analytics. However, I note that there is nothing to say that you can review or check up on your current usage for the month. I have administrator access to the Google Analytics account, but I see no feature that lets me check up on my monthly usage. I don't know if Google offer this, either by means of the admin interface or via their support channels - but it would certainly be a useful feature. Is there anyway for a free GA user to obtain this information?

• Is it a bad practice to store large files (10 MB) in a database?

  - by B Seven

  I am currently creating a web application that allows users to store and share files, 1 MB - 10 MB in size. It seems to me that storing the files in a database will significantly slow down database access. Is this a valid concern? Is it better to store the files in the file system and save the file name and path in the database? Are there any best practices related to storing files when working with a database? I am working in PHP and MySQL for this project, but is the issue the same for most environments (Ruby on Rails, PHP, .NET) and databases (MySQL, PostgreSQL).

• Oracle VM RAC template - what it took

  - by wcoekaer

  In my previous posting I introduced the latest Oracle Real Application Cluster / Oracle VM template. I mentioned how easy it is to deploy a complete Oracle RAC cluster with Oracle VM. In fact, you don't need any prior knowledge at all to get a complete production-ready setup going. Here is an example... I built a 4 node RAC cluster, completely configured in just over 40 minutes - starting from import template into Oracle VM, create VMs to fully up and running Oracle RAC. And what was needed? 1 textfile with some hostnames and ip addresses and deploycluster.py. The setup is a 4 node cluster where each VM has 8GB of RAM and 4 vCPUs. The shared ASM storage in this case is 100GB, 5 x 20GB volumes. The VM names are racovm.0-racovm.3. The deploycluster script starts the VMs, verifies the configuration and sends the database cluster configuration info through Oracle VM Manager to the 4 node VMs. Once the VMs are up and running, the first VM starts the actual Oracle RAC setup inside and talks to the 3 other VMs. I did not log into any VM until after everything was completed. In fact, I connected to the database remotely before logging in at all. # ./deploycluster.py -u admin -H localhost --vms racovm.0,racovm.1,racovm.2,racovm.3 --netconfig ./netconfig.ini Oracle RAC OneCommand (v1.1.0) for Oracle VM - deploy cluster - (c) 2011-2012 Oracle Corporation (com: 26700:v1.1.0, lib: 126247:v1.1.0, var: 1100:v1.1.0) - v2.4.3 - wopr8.wimmekes.net (x86_64) Invoked as root at Sat Jun 2 17:31:29 2012 (size: 37500, mtime: Wed May 16 00:13:19 2012) Using: ./deploycluster.py -u admin -H localhost --vms racovm.0,racovm.1,racovm.2,racovm.3 --netconfig ./netconfig.ini INFO: Login password to Oracle VM Manager not supplied on command line or environment (DEPLOYCLUSTER_MGR_PASSWORD), prompting...

• data maintenance/migrations in image based sytems

  - by User

  Web applications usually have a database. The code and the database work hand in hand together. Therefore Frameworks like Ruby on Rails and Django create migration files Sure there are also servers written in Self or Smalltalk or other image-based systems that face the same problem: Code is not written on the server but in a separate image of the programmer. How do these systems deal with a changing schema, changing classes/prototypes. Which way do the migrations go? Example: What is the process of a new attribute going from programmer's idea to the server code and all objects? I found the Gemstone/S manual chapter 8 but it does not really talk about the process of shipping code to the server.

• How can I allow unprivileged users to shutdown from the panel? (no sudo)

  - by potofcoffee

  I set up an old PC with Edubuntu 12.04 for my girls, with an admin account for myself and normal user accounts for both of them. Unfortunately, they are not able to shut down the computer by themselves with this configuration. Choosing shutdown from the (Unity) panel menu will log them out, but that's it. How do I give them shutdown privileges? Please note that they are 5 and 7 years old and just starting to find their way around a computer. Solutions that would require them to open a terminal and sudo whatever are not helpful -- and I don't want them to be able to sudo anything, anyway. I need the panel menu entry "Shutdown" to work for them.

• Ops Center 12.1.4 Released

  - by Owen Allen

  Ops Center version 12.1.4.0.0, an update for 12c, has just been released. There are a few new features. The biggest one is support for multiple Automated Installer install services, which means that you can provision any version of Oracle Solaris 11, rather than just one. We've also added support for multi-file VM templates, and enhanced the network configuration support for vServers. You can take a look at the What's New document for more information about the new features. If you're already using Ops Center, you can download the 12.1.4 upgrade through the UI, or get it from the Oracle Tech Network or from e-delivery. The Upgrade chapter in the Admin Guide explains how to perform the upgrade.

• AWStats: cannot access /var/log/apache2/access.log

  - by Joril

  I installed awstats on my new Ubuntu Lucid server, but when cron tries to run it as user www-data, it complains that cannot access /var/log/apache2/access.log: Permission denied. In /usr/share/doc/awstats/README.Debian there's this paragraph: By default Apache stores (since version 1.3.22-1) logfiles with uid=root and gid=adm, so you need to either... 1) Change the rights of the logfiles in /etc/logrotate.d/apache so that www-data has at least read access. 2) As 1) but change to a specific user, and use the suEXEC feature of Apache to run as same user (and either change the right of /var/lib/awstats as well or use another directory). This is more complicated, but then the logs are not generally accessible to the server (which was probably the point of the Apache default). 3) Change awstats.pl to group adm (but beware that you are then taking the risk of allowing a CGI-script access to admin stuff on the machine!). I'd go with 1, but what are the recommended permissions to grant?

• Unable to log in to ubuntu server 10.04 after trying to join windows domain

  - by nash

  I was trying to join our ubuntu 10.04 server to the windows domain and I ended up editing the pam.d configuration files. My aim was to have domain users log into the ubuntu server with their domain accounts in order to access some applications instead of creating new unix users each time. My system admin says the join was successful to the domain. Now I have no way of logging into the sever. Is there a way I can undo everything and get the server back to the original login using the local account? I will also appreciate if someone pointed me to some configuration that actually worked - I am still willing to try and make it work.

• cPanel email doesn't seem to work - error 550?

  - by Megh

  I am fairly new to the web hosting game, so bear with me :) Recently set up a VPS with cPanel and WHM. Everything is going well so far, I've created a user domain and transferred my website there, managed a couple of databases with phpmyadmin, everything was going great until I started messing around with email. I made an email account [email protected] through cPanel, although when I try and email this address I get the following error: Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 Unknown user (state 13) Quite unsure of what to do next, in all honesty.

• What are the warning signs of impending doom to watch out for on a project?

  - by ConroyP

  Having worked on a failed project is one of the few things that most programmers have in common, regardless of language used, industry or experience. These projects can be great learning experiences, soul-crushing disasters (or both!), and can occur for a multitude of reasons: upper management change of heart under-skilled / under-resourced team emergence of superior competitor during dev cycle over/under management Once you've worked on a couple of such projects, is it possible to recognise at an early stage exactly when a project is doomed to fail? For me, a big sign is having a hard & fast external deadline combined with feature creep. I've seen projects which were well planned out and proceeding right on schedule go horribly off the rails once the late feature requests started to roll in and get added to the final "deliverable". The proposers of these requests earned the nickname of Columbo, due to rarely leaving the room without asking for "just one more thing". What are the warning signs you look out for that set off the alarm bells of impending doom in your head?

• How abstract should you get with BDD

  - by Newton

  I was writing some tests in Gherkin (using Cucumber/Specflow). I was wondering how abstract should I get with my tests. In order to not make this open-ended, which of the following statements is better for BDD: Given I am logged in with email [email protected] and password 12345 When I do something Then something happens as opposed to Given I am logged in as the Administrator When I do something Then something happens The reason I am confused is because 1 is more based on the behaviour (filing in email and password) and 2 is easier to process and write the tests.

• Would you make your website's source code public?

  - by Karpie

  Back story: My best friend is a self-taught coder for a community art site, written in PHP. Some time ago he mentioned he wanted to make the source code of the site public, to which my response was total horror - surely it was going to be full of security holes waiting to be found, and it was going to lead to hacking and errors on a huge scale. He never ended up doing it. Current story: I'm starting development of a community website built in Rails, and for ease of use I was going to use Github for version control. Then I realized it was pretty much exactly the same thing as my friend making his source code public - which made me stop and think. Would you make your website's completely-custom source code public? Or is this a case of open source gone too far? (note: I don't think this applies to people who run things like Wordpress. Or does it?)

• Is there such a thing as too much experience?

  - by sunpech

  For modern software developers in today's world, is there such a thing as having too much experience with a certain technology or programming language? To a recruiter, interviewer, or company hiring-- could there often be cases where a particular candidate has so much experience in a certain area or technology where it works against the candidate to being hired? I'm not talking about cases where a senior developer is applying for an entry-level developer position, and has a lot of experience in that sense. Nor am I talking about cases where a candidate is outright lying (e.g. 20+ years experience with Ruby on Rails). I've overheard this in conversations between hiring managers/developers during happy hours, yet I'm not quite sure I fully understand what they mean.

• Creating the Business Card Request InfoPath Form

  - by JKenderdine

  Business Card Request Demo Files Back in January I spoke at SharePoint Saturday Virginia Beach about InfoPath forms and Web Part deployment.  Below is some of the information and details regarding the form I created for the session.  There are many blogs and Microsoft articles on how to create a basic form so I won’t repeat that information here.   This blog will just explain a few of the options I chose when creating the solutions for SPS Virginia Beach.  The above link contains the zipped package files of the two InfoPath forms(no code solution and coded solution), the list template for the Location list I used, and the PowerPoint deck.  If you plan to use these templates, you will need to update the forms to work within your own environments (change data connections, code links, etc.).  Also, you must have the SharePoint Enterprise version, with InfoPath Services configured in order to use the Web Browser enabled forms. So what are the requirements for this template? Business Card Request Form Template Design Plan: Gather user information and requirements for card Pull in as much user information as possible. Use data from the user profile web services as a data source Show and hide fields as necessary for requirements Create multiple views – one for those submitting the form and Another view for the executive assistants placing the orders. Browser based form integrated into SharePoint team site Submitted directly to form library The base form was created using the blank template.  The table and rows were added using Insert tab and selecting Custom Table.  The use of tables is a great way to make sure everything lines up.  You do have to split the tables from time to time.  If you’ve ever split cells and then tried to re-align one to find that you impacted the others, you know why.  Here is what the base form looks like in InfoPath.   Show and hide fields as necessary for requirements You will notice I also used Sections within the form.  These show or hide depending on options selected or whether or not fields are blank.  This is a great way to prevent your users from feeling overwhelmed with a large form (this one wouldn’t apply).  Although not used in this one, you can also use various views with a tab interface.  I’ll show that in another post. Gather user information and requirements for card Pull in as much user information as possible. Use data from the user profile web services as a data source Utilizing rules you can load data when the form initiates (Data tab, Form Load).  Anything you can automate is always appreciated by the user as that is data they don’t have to enter.  For example, loading their user id or other user information on load: Always keep in mind though how much data you load and the method for loading that data (through rules, code, etc.).  They have an impact on form performance.  The form will take longer to load if you bring in a ton of data from external sources.  Laura Rogers has a great blog post on using the User Information List to load user information.   If the user has logged into SharePoint, then this can be used quite effectively and without a huge performance hit.   What I have found is that using the User Profile service via code behind or the Web Service “GetUserProfileByName” (as above) can take more time to load the user data.  Just food for thought. You must add the data connection in order for the above rules to work.  You can connect to the data connection through the Data tab, Data Connections or select Manage Data Connections link which appears under the main data source.  The data connections can be SharePoint lists or libraries, SQL data tables, XML files, etc.  Create multiple views – one for those submitting the form and Another view for the executive assistants placing the orders. You can also create multiple views for the users to enhance their experience.  Once they’ve entered the information and submitted their request for business cards, they don’t really need to see the main data input screen any more.  They just need to view what they entered. From the Page Design tab, select New View and give the view a name.  To review the existing views, click the down arrow under View: The ReviewView shows just what the user needs and nothing more: Once you have everything configured, the form should be tested within a Test SharePoint environment before final deployment to production.  This validates you don’t have any rules or code that could impact the server negatively. Submitted directly to form library   You will need to know the form library that you will be submitting to when publishing the template.  Configure the Submit data connection to connect to this library.  There is already one configured in the sample,  but it will need to be updated to your environment prior to publishing. The Design template is different from the Published template.  While both have the .XSN extension, the published template contains all the “package” information for the form.  The published form is what is loaded into Central Admin, not the design template. Browser based form integrated into SharePoint team site In Central Admin, under General Settings, select Manage Form Templates.  Upload the published form template and Activate it to a site collection. Now it is available as a content type to select in the form library.  Some documentation on publishing form templates:  Technet – Manage administrator approved form templates And that’s all our base requirements.  Hope this helps to give a good start.

• Prevent Apache restarting automatically after upgrading packages

  - by HorusKol

  Following on from an earlier question: Is there a way to download security updates and notify admin without installing the update? A large number of packages interact with Apache (especially PHP) such that security updates to those packages can cause the server to attempt to restart the service. While my earlier question was answered, I'm now thinking that I need a different solution. So - is there are way to allow security updates to be applied using apt, have an email sent to an administrator, and, most importantly, prevent services from being restarted at the end of the installation/update process? The administrator will then be able to log in and restart the service manually.

• New promising webdevelopment language?

  - by Rick

  I'm looking for a new language focused on webdevelopment. I know there are many current language/framework combination that are very suited for webdevelopment; ASP.Net, Ruby on Rails, PHP with numerous frameworks, etc... I like shiny new things! I like digging through language documentation or even an interpreter to figure out why something is not working the way I expect it to. Sure I could use an existing solution, but that wouldn't be fun! Are there any new up and coming language focused to webdevelopment (optionally language + webframework setup would be fine too)?

• Which data structure you will use to for a witness list?

  - by mateen

  I'm making a game where the plot is a bank robbery. Lots of people witness that robbery. The game will load a list of suspects, while the players (witnesses) will have to identify the suspects of this robbery. The game should load a list of suspects to identify the one as quickly as possible. Admin can add/remove suspects in the lists and two or more lists of suspects can also be merged into one (to show it to the player). The question is which data structure will be suitable to develop the lists?

• Insanity joining Server 12.04 to Windows AD

  I've seen lots of stuff about this error on the internet, but had no luck implementing a solution. I'm trying to use Likewise-Open to join an Ubuntu Server 12.04 machine to a Windows Active Dicrectory domain controller and having absolutely no luck. I run: sudo domainjoin-cli join my.domain.gob ADMINISTRATOR and get back (after putting in the admin password): Error: DNS_ERROR_BAD_PACKET [code 0x0000251e] A bad packet was recieved from a DNS server. Potentially the requested address does not exist. I have heard that WAD insists on being your only nameserver, and in attempts to make that work, I've tried editing /etc/resolv.conf and /etc/network/interfaces but none of that has worked either. Ideas?
