  • Mapping an amazon server to a domain name registered with name.com

    - by S4M
    I have an amazon S3 web server and a domain name registered in name.com (the name is sam-experiments.com). I am trying to have a static page hosted on the amazon web server to be displayed on http://www.sam-experiments.com On the web server side, my bucket name is 'www.sam-experiments.com', and it links to here: http://www.sam-experiments.com.s3-website-eu-west-1.amazonaws.com/ On name.com, I added a new record with the followin characteristics: Record Type: CNAME Record Host: www.sam-experiments.com Record Answer: www.sam-experiments.com.s3.amazonaws.com. (as specified in the documentation here: http://docs.amazonwebservices.com/AmazonS3/latest/dev/VirtualHosting.html#VirtualHostingCustomURLs) TTL: 300 However, nothing gets displayed on www.sam-experiments.com, and I am not able to find what I am doing wrong. I really would appreciate some tip. Thanks! Note: I already posted this question in stackoverflow, but didnt get any answer, so I thought posting here may be more appropriate.

  • Mac OS X behind OpenLDAP and Samba

    - by Sam Hammamy
    I have been battling for a week now to get my Mac (Mountain Lion) to authenticate on my home network's OpenLDAP and Samba. From several sources, like the Ubuntu community docs, and other blogs, and after a hell of a lot of trial and error and piecing things together, I have created a samba.ldif that will pass the smbldap-populate when combined with apple.ldif and I have a fully functional OpenLDAP server and a Samba PDC that uses LDAP to authenticate the OS X Machine. The problem is that when I login, the home directory is not created or pulled from the server. I get the following in system.log Sep 21 06:09:15 Sams-MacBook-Pro.local SecurityAgent[265]: User info context values set for sam Sep 21 06:09:15 Sams-MacBook-Pro.local authorizationhost[270]: in pam_sm_authenticate(): Got user: sam Sep 21 06:09:15 Sams-MacBook-Pro.local authorizationhost[270]: in pam_sm_authenticate(): Got ruser: (null) Sep 21 06:09:15 Sams-MacBook-Pro.local authorizationhost[270]: in pam_sm_authenticate(): Got service: authorization Sep 21 06:09:15 Sams-MacBook-Pro.local authorizationhost[270]: in od_principal_for_user(): no authauth availale for user.

  • IASA South East Florida Chapter Meeting Recap - June 2011

    - by Sam Abraham
    Erik Russell and Giles Marino were our speakers for the June 2011 IASA South East Florida Chapter meeting.    Attendees filled all available seats at the Microsoft office conference room where the event was held. This highlights the high interest in Enterprise Architecture as a career track and chartered project role. Also in attendance were our Board of Directors and Alex Funkhouser, President, Sherlock Technology.   Rainer Habermann, Chapter President, kicked off the meeting by introducing our speakers and Board of Directors.   Alex Funkhouser, President of South Florida’s staffing firm Sherlock Technology spoke briefly about available Software Architect positions in the area. Alex also congratulated and presented this week’s Sherlock Raffle winner with $500 in cash.   Our speakers Giles and Erik then proceeded with their talk. Erik presented a business case in the government sector where Enterprise Architecture helped a government entity cut costs and streamline its various business operations. Technologies leveraged in Erik’s demonstrated project were Java-based.   Giles then followed with a thorough demonstration of the Architecture patterns he used to migrate a complete backend system for an insurance company to the .Net Platform.   Audience was very engaged with our speakers as evidenced by the large number of follow-up questions asked at the end of the talk.   We greatly enjoyed Giles and Erik’s talk and look forward to having them share with us more of their adventures as Enterprise Architects in the near future.   Below are some photos of the event.   Sam Abraham Secretary- IASA South East Florida Chapter. http://www.iasaglobal.org/iasa/South_East_Florida.asp Chapter President - Rainer Habermann kicks off our meeting.   Sherlock Technology President Alex Funkhouser holding Sherlock's weekly cash prize.

  • YUI Calendar: how does it load the Sam's Skin CSS?

    - by dound
    I'm using YUI 2's calendar in YUI 3. How does it load Sam's skin CSS? I didn't manually include it (though it seems like I should so the user can download it in the one request I make to the combo loader for css). Strangely, I don't see it being downloaded nor do I see it in the JS files themselves. I must be overlooking it. This is how I'm loading the CSS and JS now: <head> ... <link rel="stylesheet" type="text/css" href="http://yui.yahooapis.com/combo?3.1.0/build/cssreset/reset.css&amp;3.1.0/build/cssfonts/fonts.css&amp;3.1.0/build/cssbase/base.css"/> ... </head> ... <!--and at the end of the body tag:--> <script type="text/javascript" src="http://yui.yahooapis.com/combo?3.1.1/build/yui/yui-min.js&amp;3.1.1/build/oop/oop-min.js&amp;3.1.1/build/event-custom/event-custom-base-min.js&amp;3.1.1/build/event/event-base-min.js&amp;3.1.1/build/json/json-parse-min.js&amp;3.1.1/build/querystring/querystring-stringify-simple-min.js&amp;3.1.1/build/io/io-base-min.js&amp;3.1.1/build/dom/dom-base-min.js&amp;3.1.1/build/dom/selector-native-min.js&amp;3.1.1/build/dom/selector-css2-min.js&amp;3.1.1/build/node/node-base-min.js&amp;3.1.1/build/node/node-style-min.js&amp;3.1.1/build/stylesheet/stylesheet-min.js&amp;2in3.1/2.8.0/build/yui2-calendar/yui2-calendar-min.js&amp;2in3.1/2.8.0/build/yui2-yahoo/yui2-yahoo-min.js&amp;2in3.1/2.8.0/build/yui2-dom/yui2-dom-min.js&amp;2in3.1/2.8.0/build/yui2-event/yui2-event-min.js"></script> <script type="text/javascript">//<![CDATA[ YUI().use('yui2-calendar', function(Y) { var YAHOO = Y.YUI2; var cal = new YAHOO.widget.Calendar("cal",{navigator:true,mindate:'1/1/2000'); cal.render(); // ... Edit: I want to make a few minor changes to the default sam skin. What is the best way to do that? I answered this part of my question. If I wrap the calendar in an extra div, then specifying CSS rules which include that div as part of the selector makes the rule more specific so the browser uses it over Sam's skin. Rough example: <style type="text/css"> .magic .yui-skin-sam .yui-calendar td.calcell { height: 10em; width: 15em; } </style> ... <div class="magic"> <div class="yui-skin-sam"> <div id="cal"></div> </div> </div>

  • Packages are not available for installation

    Changing some Software Update settings I possibly corrupted something, and now I don't see many packages in the list.

  • Simple python oo issue

    - by Alex K
    Hello, Have a look a this simple example. I don't quite understand why o1 prints "Hello Alex" twice. I would think that because of the default self.a is always reset to the empty list. Could someone explain to me what's the rationale here? Thank you so much. class A(object): def __init__(self, a=[]): self.a = a o = A() o.a.append('Hello') o.a.append('Alex') print ' '.join(o.a) # >> prints Hello Alex o1 = A() o1.a.append('Hello') o1.a.append('Alex') print ' '.join(o1.a) # >> prints Hello Alex Hello Alex

  • After Filter redirects to login.jsp, proper servlet doesnt get called

    - by gnomeguru
    My simple project structure is shown in this link. I am using Eclipse and Tomcat 6. There is login.jsp which submits its form to login_servlet. The login_servlet sets a session variable and then redirects to home.jsp. The home.jsp file has links to the 4 JSP files under a directory called /sam. In web.xml I have given the url-pattern as /sam/* for the LogFiler filter. The LogFilter just reads the session variable and does doChain(request,resposne) if valid, else it redirects to /login.jsp. RequestDispatcher rd = request.getRequestDispatcher("/login.jsp"); rd.forward(request,response); Basically I don't want anyone to access files inside /sam directory directly. Now let's say, I try to directly access a file inside /sam directory, the filter kicks in and the redirection to login.jsp works and even the broswers contents are that of login.jsp, but the url in the browser doesn't change. When I enter details and press submit, instead of sending the data to login_servlet, it sends it to sam/login_servlet and then tomcat tells me there is no such servlet here! Obviously there isn't. My doubt is why is it sending it so sam/login_servlet instead of /login_servlet which is usually what it does when I start running the login.jsp on my own. One more thing, is there a way I can apply the servlet to ONLY .jsp files inside /sam diectory? I tried giving the url-pattern like /sam/*.jsp, but Tomcat was refusing to accept that url-pattern.

  • Custom PHPINIDir setting in VirtualHost affecting other VirtualHosts

    - by Radio
    One of the clients requested a personal php.ini configuration for his website, so I have set his VirtualHost as follows: <VirtualHost *:80> DocumentRoot "/home/alex/www.domain.tld" ServerName www.domain.tld AssignUserID alex alex PHPINIDir /home/alex/php.ini </VirtualHost> The client created php.ini file under /home/alex/ which contains only this setting: session.save_path = "/home/alex/.php_sessions/" Afterall he started to complaint that he sees all other session files generated by other clients' websites. After doing some basic troubleshooting, I realized, that his php.ini settings are affecting all websites specified in the httpd-vhosts.conf. Question is why? Since PHPINIDir is only specified inside one specific VirtualHost?

  • Regex to identify rows that do not contain exact number of occurences of quotemark character using Notepad++

    - by SamAspin
    I would like to be able to jump to rows that dont contain 6 quotemarks in a quoted-CSV file as it feels like a good way to identify broken rows. I think using a regular expression with Notepad++'s find features would be a sensible approach but I'm not sure how to pick the rows up. 6 quotemarks (") would suggest a complete row so I want to skip to any row that does not contain 6. Here is some sample data to play with, in this example its the 4th line I'd like to jump to "sam","mark","dave" "sam","mark","dave" "sam","mark","dave" "sam","mark"," dave" "sam","mark","dave" "sam","mark","dave"

For example, we'll call my server 'Sam' and my laptop 'Luke'. I'd like a user on Luke to be able to execute a reverse port forward ssh command to Sam, so that port 4321 on Sam is tunneled to port 4321 on Luke. For example: ssh -fnR 4321:localhost:4321 -l limitedUser Sam How can I create a user on Sam that is only allowed to execute this command?

  • Merge\Combine two datatables

    - by madlan
    I'm trying to merge\combine two datatables. I've looked at various examples and answers but they seem to create duplicate rows or require indexes (merge on datatable etc) I can't do this via SQL as one source is from a linked Oracle server accessed via MSSQL and the other from a different MSSQL Server that does not have linked access. The data is currently very simple: Name, Email, Phone DataTable1: "John Clark", "", "01522 55231" "Alex King", "alex[email protected]", "01522 55266" "Marcus Jones", "[email protected]", "01522 55461" DataTable2: "John Clark", "[email protected]", "01522 55231" "Alex King", "alex[email protected]", "" "Marcus Jones", "[email protected]", "01522 55461" "Warren bean", "[email protected]", "01522 522311" Giving a datatable with the following: "John Clark", "[email protected]", "01522 55231" "Alex King", "alex[email protected]", "01522 55266" "Marcus Jones", "[email protected]", "01522 55461" "Warren bean", "[email protected]", "01522 522311" Name is the field to match records on, with the first datatable taking priority.

  • How can I select values from different rows depending on the most recent entry date, all for the sam

    - by user321185
    Basically I have a table which is used to hold employee work wear details. It is formed of the columns: EmployeeID, CostCentre, AssociateLevel, IssueDate, TrouserSize, TrouserLength, TopSize & ShoeSize. An employee can be assigned a pair of trousers, a top and shoes at the same time or only one or two pieces of clothing. As we all know peoples sizes and employee levels can change which is why I need help really. Different types of employees (associatelevels) require different colours of clothing but you can ignore this part. Everytime an employee receives an item of clothing a new row will be inserted into the table with an input date. I need to be able to select the most recent clothes size for each item of clothing for each employee. It is not necessary for all the columns to hold values because an employee could receive trousers or poloshirts at different times in the year. So for example if employee '54664LSS' was given a pair of 'XL' trousers and a 'L' top on 24/03/11 but then received a 'M' top on 26/05/10. The input of these items would be help on two different rows obviously. So if I wanted to select the most recent clothing for each clothes category. Then the values of the 'M' sized top and the 'L' sized trousers would need to be returned. Any help would be greatly appreciated as I'm pretty stuck :(. Thanks.

    Hi, I have a table which contains names: Name ---- John Smith John Smith Sam Wood George Wright John Smith Sam Wood I want to create a select statement which shows this: Name 'John Smith 1' 'John Smith 2' 'Sam Wood 1' 'George Wright 1' 'John Smith 3' 'Sam Wood 2' In other words, I want to add separate counters to each name. Is there a way to do it without using cursors?
