• apache 2.2: how can I set up a VirtualHost inside the RootDirectory?

  - by redraw

  I want to set up a VirtualHost inside the RootDirectory. For example, My project is in C:/myproject and I want to access with http://localhost/myproject EDIT: I've made an alias inside the httpd-vhosts.conf, however I don't have permissions. <VirtualHost *:80> DocumentRoot "C:/apache-2.2/htdocs" ServerName localhost Alias /test "D:\arbol\documentos\test" </VirtualHost> Is this code below the proper way to give permissions? <VirtualHost *:80> DocumentRoot "C:/apache-2.2/htdocs" ServerName localhost Alias /test "D:\arbol\documentos\test" <Directory "D:\arbol\documentos\test"> allow from all order allow,deny AllowOverride All </Directory> </VirtualHost>

• What is the difference between String and string in C#

  - by SAMIR BHOGAYTA

  string : ------ The string type represents a sequence of zero or more Unicode characters. string is an alias for String in the .NET Framework. 'string' is the intrinsic C# datatype, and is an alias for the system provided type "System.String". The C# specification states that as a matter of style the keyword ('string') is preferred over the full system type name (System.String, or String). Although string is a reference type, the equality operators (== and !=) are defined to compare the values of string objects, not references. This makes testing for string equality more intuitive. For example: String : ------ A String object is called immutable (read-only) because its value cannot be modified once it has been created. Methods that appear to modify a String object actually return a new String object that contains the modification. If it is necessary to modify the actual contents of a string-like object Difference between string & String : ---------- ------- ------ - ------ the string is usually used for declaration while String is used for accessing static string methods we can use 'string' do declare fields, properties etc that use the predefined type 'string', since the C# specification tells me this is good style. we can use 'String' to use system-defined methods, such as String.Compare etc. They are originally defined on 'System.String', not 'string'. 'string' is just an alias in this case. we can also use 'String' or 'System.Int32' when communicating with other system, especially if they are CLR-compliant. I.e. - if I get data from elsewhere, I'd deserialize it into a System.Int32 rather than an 'int', if the origin by definition was something else than a C# system.

• Use a custom domain and point to Tumblr blog

  - by jskye

  My domain mydomain.com is registered with GoDaddy. I wish to host my Tumblr blog on this domain with Nearly Free Speech hosting. My active nameservers at GoDaddy already point to my authoritative ones at Nearly Free Speech which is working. However I'm baffled as to how to get my correct configuration to point to my Tumblr. Preferably I'd like (A) my domain http://mydomain.com to host the blog and have http://www.mydomain.com redirect also to http://mydomain.com. If this is too difficult my next preference is (B) to have http://www.mydomain.com host the blog whilst http://mydomain.com redirects to http://www.mydomain.com My third preference is to have (C) a sub-domain like http://tumblr.mydomain.com or http://tumblr.mydomain.com to host the blog and I guess have http://mydomain.com and http://www.mydomain.com both redirect to it. I've tried having two aliases mydomain.com and www.mydomain.com pointing to my permanent Nearly Free Speech IP at mydomain.nfshost.com and when I try to add: (1) an A record pointing mydomain.com to the IP 66.6.44.4 as per Tumblr's instructions it tells me I already have the bare domain as an alias so I cant do that. (2) the A record on the www.mydomain.com alias. I can do this with either www.mydomain.com set as an alias or not. But when I tried this with mydomain.com set as the canonical name the result when visiting either mydomain.com or www.mydomain.com was both of them continually redirecting to each other until an error was thrown. So I was wondering if there is a ninja that could save me some hair-pulling and tell me the correct way to config A, or else B, or else C.

• New features in SQL Prompt 6.4

  - by Tom Crossman

  We’re pleased to announce a new beta version of SQL Prompt. We’ve been trying out a few new core technologies, and used them to add features and bug fixes suggested by users on the SQL Prompt forum and suggestions forum. You can download the SQL Prompt 6.4 beta here (zip file). Let us know what you think! New features Execute current statement In a query window, you can now execute the SQL statement under your cursor by pressing Shift + F5. For example, if you have a query containing two statements and your cursor is placed on the second statement: When you press Shift + F5, only the second statement is executed:   Insert semicolons You can now use SQL Prompt to automatically insert missing semicolons after each statement in a query. To insert semicolons, go to the SQL Prompt menu and click Insert Semicolons. Alternatively, hold Ctrl and press B then C. BEGIN…END block highlighting When you place your cursor over a BEGIN or END keyword, SQL Prompt now automatically highlights the matching keyword: Rename variables and aliases You can now use SQL Prompt to rename all occurrences of a variable or alias in a query. To rename a variable or alias, place your cursor over an instance of the variable or alias you want to rename and press F2: Improved loading dialog box The database loading dialog box now shows actual progress, and you can cancel loading databases:   Single suggestion improvement SQL Prompt no longer suggests keywords if the keyword has been typed and no other suggestions exist. Performance improvement SQL Prompt now has less impact on Management Studio start up time. What do you think? We want to hear your feedback about the beta. If you have any suggestions, or bugs to report, tell us on the SQL Prompt forum or our suggestions forum.

• Speed up ADF Mobile Deployment to Android with Keystore

  - by Shay Shmeltzer

  As you might have noticed from my latest ADF Mobile entries, I'm doing most of my ADF Mobile development on a windows machine and testing on an Android device. Unfortunately the Android/windows experience is not as fast as the iOS/Mac one. However, there is one thing I learned today that can make this a bit less painful in terms of the speed to deploy and test your application - and this is to use the "Release" mode when deploying your application instead of the "Debug" mode. To do this you'll first need to define a keystore, but as Joe from our Mobile team showed me today, this is quite easy. Here are the steps: Open a command line in your JDK bin directory (I just used the JDK that comes with the JDeveloper install). Issue the following command: keytool –genkey –v –keystore <Keystore Name>.keystore –alias <Alias Name> -keyalg RSA –keysize 2048 –validity 10000 Both keystore name and alias names are strings that you decide on. The keytool utility will then prompt you with various questions that you'll need to answer. Once this is done, the next step is to configure your JDeveloper preferences->ADF Mobile to add this keystore there under the release tab:  Then for your application specific deployment profile - switch the build mode from debug to release. The end result is a much smaller mobile application (for example from 60 to 21mb) and a much faster deployment cycle (for me it is about twice as fast as before).

• Password not working for sudo ("Authentication failure")

  - by Souta

  Before I mention anything further, DO NOT give me a response saying that terminal won't show password input. I'm AWARE of that. I'm typing my user password in (not a capslock issue), and for some reason it still says 'Authentication Failure'. Is there some other password (one I'm not aware of) I'm supposed to be using other than my user password? I've had this ubuntu before, on another hard drive and I didn't have this problem. (And it was the same ubuntu, ubuntu 12.04 LTS) ai@AiNekoYokai:~$ groups ai adm cdrom sudo dip plugdev lpadmin sambashare ai@AiNekoYokai:~$ lsb_release -rd Description: Ubuntu 12.04 LTS Release: 12.04 ai@AiNekoYokai:~$ pkexec cat /etc/sudoers # # This file MUST be edited with the 'visudo' command as root. # # Please consider adding local content in /etc/sudoers.d/ instead of # directly modifying this file. # # See the man page for details on how to write a sudoers file. # Defaults env_reset Defaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin" # Host alias specification # User alias specification # Cmnd alias specification # User privilege specification root ALL=(ALL:ALL) ALL # Members of the admin group may gain root privileges %admin ALL=(ALL) ALL # Allow members of group sudo to execute any command %sudo ALL=(ALL:ALL) ALL # See sudoers(5) for more information on "#include" directives: #includedir /etc/sudoers.d I can log in with my password, but it's not accepted as valid for authentication <-- That is pretty much my issue. (Although, I haven't gone into recovery mode.) I've ran: ai@AiNekoYokai:~$ ls /etc/sudoers.d README And also reinstalled sudo with: pkexec apt-get update pkexec apt-get --purge --reinstall install sudo pkexec usermod -a -G admin $USER <- Says admin does not exist su $USER <- worked for me, however, my password still does not do much (in sense of not working for other things) I changed my password with pkexec passwd $USER. I was able to change it no problem. gksudo xclock was something I was able to get into, no problem. (Clock showed) ai@AiNekoYokai:~$ gksudo xclock

• SQL SERVER – Maximize Database Performance with DB Optimizer – SQL in Sixty Seconds #054

  - by Pinal Dave

  Performance tuning is an interesting concept and everybody evaluates it differently. Every developer and DBA have different opinion about how one can do performance tuning. I personally believe performance tuning is a three step process Understanding the Query Identifying the Bottleneck Implementing the Fix While, we are working with large database application and it suddenly starts to slow down. We are all under stress about how we can get back the database back to normal speed. Most of the time we do not have enough time to do deep analysis of what is going wrong as well what will fix the problem. Our primary goal at that time is to just fix the database problem as fast as we can. However, here is one very important thing which we need to keep in our mind is that when we do quick fix, it should not create any further issue with other parts of the system. When time is essence and we want to do deep analysis of our system to give us the best solution we often tend to make mistakes. Sometimes we make mistakes as we do not have proper time to analysis the entire system. Here is what I do when I face such a situation – I take the help of DB Optimizer. It is a fantastic tool and does superlative performance tuning of the system. Everytime when I talk about performance tuning tool, the initial reaction of the people is that they do not want to try this as they believe it requires lots of the learning of the tool before they use it. It is absolutely not true with the case of the DB optimizer. It is a very easy to use and self intuitive tool. Once can get going with the product, in no time. Here is a quick video I have build where I demonstrate how we can identify what index is missing for query and how we can quickly create the index. Entire three steps of the query tuning are completed in less than 60 seconds. If you are into performance tuning and query optimization you should download DB Optimizer and give it a go. Let us see the same concept in following SQL in Sixty Seconds Video: You can Download DB Optimizer and reproduce the same Sixty Seconds experience.

• BigData and Customer Experience: Happy Together

  - by Isabel F. Peñuelas

  The two big buzzes of the year may lay closer than it appears. Both concepts intersect at various points: BigData and Return of Investment of Marketing Campaigns On a recent post Big Data Is The Future Of Marketing Jeff Dachis explains very clearly how “Big data analytics finally allows marketers to identify, measure, and manage what is positively impacting their Brand”. Regression analysis applied to big data volumes coming from social media will substitute the failed attempts to justify marketing investments on social media in terms of followers and likes, he continues, “the measurement models applied by marketers on TV Campaigns don´t work on social”, we need to study the data with fresh eyes and maybe then we will start understanding and measuring brand engagemet. Social CRM and BigData The real value of Social CRM start by analyzing mass of big data from social media in order of applying social intelligence techniques that allow us to classify new customer niches and communities and define appropriated strategies to contact potential customers. Gartner Says that the Market for Social CRM is on pace to surpass $1 Billion in Revenue by Year-End 2012 but in words of Zach Hofer-Shall, Analyst at Forrester Research “Social customer relationship management is hard” (The Social CRM Arms Race Heats ). To succeed brands need three things: Investing in new social tools, investing in consultancy and investing in infrastructure for massive data storage and analysis. Neither CeX or BigData are easy and cheap wins. But what are the customer benefits of such investments? Big Data and Brand Engagement Time is the most valuable asset of todays consumers: tired of information overload, exhausted by the terabytes of offering, anxious because of not having the same fast multichannel experience with their services’ marketers or preferred goods providers than the one they found on their social media. Yes, I know you have read this before- me too. But is real. The motto of the Customer Experience philosophy of providing a consistent experience through multiple touchpoints that makes the relationship customer/brand easier and valuable finds it basis on understanding customer/s preferences and context for which BigData analysis is another imperative. In summary, I believe that using BigData Analysis in combination with appropriated CeX strategies and technologies is a promising direction for achieving: efficiency and marketing cost-savings; growing the customer base; and increasing customer conversion and retention. In a world: The Direction of Future Marketing.

• MySQL and Hadoop Integration - Unlocking New Insight

  - by Mat Keep

  “Big Data” offers the potential for organizations to revolutionize their operations. With the volume of business data doubling every 1.2 years, analysts and business users are discovering very real benefits when integrating and analyzing data from multiple sources, enabling deeper insight into their customers, partners, and business processes. As the world’s most popular open source database, and the most deployed database in the web and cloud, MySQL is a key component of many big data platforms, with Hadoop vendors estimating 80% of deployments are integrated with MySQL. The new Guide to MySQL and Hadoop presents the tools enabling integration between the two data platforms, supporting the data lifecycle from acquisition and organisation to analysis and visualisation / decision, as shown in the figure below The Guide details each of these stages and the technologies supporting them: Acquire: Through new NoSQL APIs, MySQL is able to ingest high volume, high velocity data, without sacrificing ACID guarantees, thereby ensuring data quality. Real-time analytics can also be run against newly acquired data, enabling immediate business insight, before data is loaded into Hadoop. In addition, sensitive data can be pre-processed, for example healthcare or financial services records can be anonymized, before transfer to Hadoop. Organize: Data is transferred from MySQL tables to Hadoop using Apache Sqoop. With the MySQL Binlog (Binary Log) API, users can also invoke real-time change data capture processes to stream updates to HDFS. Analyze: Multi-structured data ingested from multiple sources is consolidated and processed within the Hadoop platform. Decide: The results of the analysis are loaded back to MySQL via Apache Sqoop where they inform real-time operational processes or provide source data for BI analytics tools. So how are companies taking advantage of this today? As an example, on-line retailers can use big data from their web properties to better understand site visitors’ activities, such as paths through the site, pages viewed, and comments posted. This knowledge can be combined with user profiles and purchasing history to gain a better understanding of customers, and the delivery of highly targeted offers. Of course, it is not just in the web that big data can make a difference. Every business activity can benefit, with other common use cases including: - Sentiment analysis; - Marketing campaign analysis; - Customer churn modeling; - Fraud detection; - Research and Development; - Risk Modeling; - And more. As the guide discusses, Big Data is promising a significant transformation of the way organizations leverage data to run their businesses. MySQL can be seamlessly integrated within a Big Data lifecycle, enabling the unification of multi-structured data into common data platforms, taking advantage of all new data sources and yielding more insight than was ever previously imaginable. Download the guide to MySQL and Hadoop integration to learn more. I'd also be interested in hearing about how you are integrating MySQL with Hadoop today, and your requirements for the future, so please use the comments on this blog to share your insights.

• Understanding Data Science: Recent Studies

  - by Joe Lamantia

  If you need such a deeper understanding of data science than Drew Conway's popular venn diagram model, or Josh Wills' tongue in cheek characterization, "Data Scientist (n.): Person who is better at statistics than any software engineer and better at software engineering than any statistician." two relatively recent studies are worth reading.   'Analyzing the Analyzers,' an O'Reilly e-book by Harlan Harris, Sean Patrick Murphy, and Marck Vaisman, suggests four distinct types of data scientists -- effectively personas, in a design sense -- based on analysis of self-identified skills among practitioners.  The scenario format dramatizes the different personas, making what could be a dry statistical readout of survey data more engaging.  The survey-only nature of the data,  the restriction of scope to just skills, and the suggested models of skill-profiles makes this feel like the sort of exercise that data scientists undertake as an every day task; collecting data, analyzing it using a mix of statistical techniques, and sharing the model that emerges from the data mining exercise.  That's not an indictment, simply an observation about the consistent feel of the effort as a product of data scientists, about data science.  And the paper 'Enterprise Data Analysis and Visualization: An Interview Study' by researchers Sean Kandel, Andreas Paepcke, Joseph Hellerstein, and Jeffery Heer considers data science within the larger context of industrial data analysis, examining analytical workflows, skills, and the challenges common to enterprise analysis efforts, and identifying three archetypes of data scientist.  As an interview-based study, the data the researchers collected is richer, and there's correspondingly greater depth in the synthesis.  The scope of the study included a broader set of roles than data scientist (enterprise analysts) and involved questions of workflow and organizational context for analytical efforts in general.  I'd suggest this is useful as a primer on analytical work and workers in enterprise settings for those who need a baseline understanding; it also offers some genuinely interesting nuggets for those already familiar with discovery work. We've undertaken a considerable amount of research into discovery, analytical work/ers, and data science over the past three years -- part of our programmatic approach to laying a foundation for product strategy and highlighting innovation opportunities -- and both studies complement and confirm much of the direct research into data science that we conducted. There were a few important differences in our findings, which I'll share and discuss in upcoming posts.

I have to say that the solution is not so easy to implement as in Analysis Services, but it just works and, from a practical point of view, it is not so difficult to implement if you understand how it works and accept its limitations (only sum and subtractions are supported).

• Powerful Lessons in Data from the Presidential Election

  - by Christina McKeon

  Now that we’ve had a few days to recover from the U.S. presidential election, it’s a good time to take a step back from politics and look for the customer experience lessons that we can take away. The most powerful lesson is that when you know more about your base, you will have an advantage over your competition. That advantage will translate into you winning and your competition losing. Michael Scherer of TIME was given access to Obama’s data analysts two days before the election. His account is documented in Inside the Secret World of the Data Crunchers Who Helped Obama Win. What we learned from Scherer’s inside view is how well Obama’s team did in getting the right data, analyzing it, and acting on it. This data team recognized how critical it was to break down data silos within the campaign. As Scherer noted, they created “a single system that merged information from pollsters, fundraisers, field workers, consumer databases, and social-media and mobile contacts with the main Democratic voter files in the swing states.” The Obama analysis was so meticulous that they knew which celebrity and which type of celebrity event would help them maximize campaign contributions. With a single system, their data models became more precise. They determined which messages were more successful with specific demographic groups and that who made the calls mattered. Data analysis also led to many other changes in Obama’s campaign including a new ad buying strategy, using social media and applications to tap into supporters’ friends, and using new social news sites. While we did not have that same inside view into Romney’s campaign, much of the post-mortem coverage indicates that Romney’s team did not have the right analysis. As Peter Hamby of CNN wrote in Analysis: Why Romney Lost, “Romney officials had modeled an electorate that looked something like a mix of 2004 and 2008….” That historical data did not account for the changing demographics in the U.S. Does your organization approach data like the Obama or Romney team? Do you really know your base? How well can you predict what is going to happen in your business? If you haven’t already put together a strategy and plan to know more, this week’s civics lesson is a powerful reason to do it sooner rather than later. Your competitors are probably thinking the same thing that you are!

This makes them pop up so that I can see them. Otherwise, it will not show my Z-5 speakers as a device that can be configured.

• mod perl in apache 2.2 not parsing perl scripts

  - by futureelite7

  Hi, I've set up a fresh Apache 2.2.15 server on windows server 2008 R2 with mod_perl (mod perl v2.0.4 / perl v5.10.1). Mod_perl and Perl 5.10 has been installed and loaded without problems. However, despite my configuration, the mod_perl module is failing to recognize and execute my .pl file, instead opting to print out the perl source instead. What did I do wrong, and how do I make perl process my pl script instead of sending it to the client? My configuration: <VirtualHost *:80> ServerAdmin [email protected] DocumentRoot "C:\Program Files (x86)\AWStats\wwwroot" ServerName analysis.example.com ServerAlias analysis.example.com ErrorLog "logs/analysis.example.com-error.log" CustomLog "logs/analysis.example.com-access.log" common DirectoryIndex index.php index.htm index.html PerlSwitches -T <Directory "C:\Program Files (x86)\AWStats\wwwroot"> Options Indexes FollowSymLinks AllowOverride None Order allow,deny Allow from all </Directory> <Directory "C:\Program Files (x86)\AWStats\wwwroot\cgi-bin"> AllowOverride None Options None Order allow,deny Allow from all <FilesMatch "\.pl$"> SetHandler perl-script # #PerlResponseHandler ModPerl::Registry PerlOptions +ParseHeaders Options +ExecCGI </FilesMatch> </directory> </VirtualHost> Many many thanks for the help!

• vim-powerline colors are out of whack in urxvt

  - by komidore64

  I have attached two images showing what my vim-powerline looks like. As you can see, something has happened to the colors and I cannot figure out how to fix it. I'm running Fedora 17 on a clean install with i3 (default config) and urxvt. Here is my bashrc: # .bashrc if [[ "$(uname)" != "Darwin" ]]; then # non mac os x # source global bashrc if [[ -f "/etc/bashrc" ]]; then . /etc/bashrc fi export TERM='xterm-256color' # probably shouldn't do this fi # bash prompt with colors # [ <user>@<hostname> <working directory> {current git branch (if you're in a repo)} ] # ==> PS1="\[\e[1;33m\][ \u\[\e[1;37m\]@\[\e[1;32m\]\h\[\e[1;33m\] \W\$(git branch 2> /dev/null | grep -e '\* ' | sed 's/^..\(.*\)/ {\[\e[1;36m\]\1\[\e[1;33m\]}/') ]\[\e[0m\]\n==> " # execute only in Mac OS X if [[ "$(uname)" == 'Darwin' ]]; then # if OS X has a $HOME/bin folder, then add it to PATH if [[ -d "$HOME/bin" ]]; then export PATH="$PATH:$HOME/bin" fi alias ls='ls -G' # ls with colors fi alias ll='ls -lah' # long listing of all files with human readable file sizes alias tree='tree -C' # turns on coloring for tree command alias mkdir='mkdir -p' # create parent directories as needed alias vim='vim -p' # if more than one file, open files in tabs export EDITOR='vim' # super-secret work stuff if [[ -f "$HOME/.workbashrc" ]]; then . $HOME/.workbashrc fi # Add RVM to PATH for scripting if [[ -d "$HOME/.rvm/bin" ]]; then # if installed PATH=$PATH:$HOME/.rvm/bin fi and my Xdefaults: !

• How to serve static files for multiple Django projects via nginx to same domain

  - by thanley

  I am trying to setup my nginx conf so that I can serve the relevant files for my multiple Django projects. Ultimately I want each app to be available at www.example.com/app1, www.example.com/app2 etc. They all serve static files from a 'static-files' directory located in their respective project root. The project structure: Home Ubuntu Web www.example.com ref logs app app1 app1 static bower_components templatetags app1_project templates static-files app2 app2 static templates templatetags app2_project static-files app3 tests templates static-files static app3_project app3 venv When I use the conf below, there are no problems for serving the static-files for the app that I designate in the /static/ location. I can also access the different apps found at their locations. However, I cannot figure out how to serve all of the static files for all the apps at the same time. I have looked into using the 'try_files' command for the static location, but cannot figure out how to see if it is working or not. Nginx Conf - Only serving static files for one app: server { listen 80; server_name example.com; server_name www.example.com; access_log /home/ubuntu/web/www.example.com/logs/access.log; error_log /home/ubuntu/web/www.example.com/logs/error.log; root /home/ubuntu/web/www.example.com/; location /static/ { alias /home/ubuntu/web/www.example.com/app/app1/static-files/; } location /media/ { alias /home/ubuntu/web/www.example.com/media/; } location /app1/ { include uwsgi_params; uwsgi_param SCRIPT_NAME /app1; uwsgi_modifier1 30; uwsgi_pass unix:///home/ubuntu/web/www.example.com/app1.sock; } location /app2/ { include uwsgi_params; uwsgi_param SCRIPT_NAME /app2; uwsgi_modifier1 30; uwsgi_pass unix:///home/ubuntu/web/www.example.com/app2.sock; } location /app3/ { include uwsgi_params; uwsgi_param SCRIPT_NAME /app3; uwsgi_modifier1 30; uwsgi_pass unix:///home/ubuntu/web/www.example.com/app3.sock; } # what to serve if upstream is not available or crashes error_page 400 /static/400.html; error_page 403 /static/403.html; error_page 404 /static/404.html; error_page 500 502 503 504 /static/500.html; # Compression gzip on; gzip_http_version 1.0; gzip_comp_level 5; gzip_proxied any; gzip_min_length 1100; gzip_buffers 16 8k; gzip_types text/plain text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript; # Some version of IE 6 don't handle compression well on some mime-types, # so just disable for them gzip_disable "MSIE [1-6].(?!.*SV1)"; # Set a vary header so downstream proxies don't send cached gzipped # content to IE6 gzip_vary on; } Essentially I want to have something like (I know this won't work) location /static/ { alias /home/ubuntu/web/www.example.com/app/app1/static-files/; alias /home/ubuntu/web/www.example.com/app/app2/static-files/; alias /home/ubuntu/web/www.example.com/app/app3/static-files/; } or (where it can serve the static files based on the uri) location /static/ { try_files $uri $uri/ =404; } So basically, if I use try_files like above, is the problem in my project directory structure? Or am I totally off base on this and I need to put each app in a subdomain instead of going this route? Thanks for any suggestions TLDR: I want to go to: www.example.com/APP_NAME_HERE And have nginx serve the static location: /home/ubuntu/web/www.example.com/app/APP_NAME_HERE/static-files/;
