Spring Security beginner's question. Build failed

- by Nitesh Panchal

Hello, I downloaded all jar files for Spring Security 3.0 and added them to my lib folder in Netbeans 6.8. Then i added Spring framework to my web application and tried to modify applicationContext.xml as given in the pdf that shipped with Spring Security. This is it's code :- <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:security="http://www.springframework.org/schema/security" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.0.xsd"> <http auto-config='true'> <intercept-url pattern="/**" access="ROLE_USER" /> </http> <authentication-manager> <authentication-provider> <user-service> <user name="jimi" password="jimispassword" authorities="ROLE_USER, ROLE_ADMIN" /> <user name="bob" password="bobspassword" authorities="ROLE_USER" /> </user-service> </authentication-provider> </authentication-manager>   </beans> This is my web.xml :- <?xml version="1.0" encoding="UTF-8"?> <web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <servlet> <servlet-name>dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>2</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dispatcher</servlet-name> <url-pattern>*.htm</url-pattern> </servlet-mapping> <session-config> <session-timeout> 30 </session-timeout> </session-config> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/applicationContext.xml</param-value> </context-param> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener> <listener> <listener-class> org.springframework.web.context.request.RequestContextListener </listener-class> </listener> <filter> <filter-name>springSecurityFilterChain</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> </filter> <filter-mapping> <filter-name>springSecurityFilterChain</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <welcome-file-list> <welcome-file>redirect.jsp</welcome-file> </welcome-file-list> </web-app> My web application doesn't compile.

Why are pieces of my HTML showing up on the page and breaking it? Is it PHP related?

- by Jason Rhodes

I've been building a site in PHP, HTML, CSS, and using a healthy dose of jQuery javascript. The site looks absolutely fine on my Mac browsers, but for some reason, when my client uses PC Safari, she's seeing strange bits of my HTML show up on the page. Here are some (small) screenshot examples: Figure 1: This one is just a closing </li> tag that should've been on the Media li element. Not much harm done, but strange. Figure 2: Here this was part of <div class='submenu'> and since the div tag didn't render properly, the entire contents of that div don't get styled correctly by CSS. Figure 3: This last example shows what should have been <a class='top current' href=... but for some reason half of the HTML tag stops being rendered and just gets printed out. So the rest of that list menu is completely broken. Here's the code from the header.php file itself. The main navigation section (seen in the screenshots) is further down, marked by a line of asterisks if you want to skip there. <?php // Setting up location variables if(isset($_GET['page'])) { $page = Page::find_by_slug($_GET['page']); } elseif(isset($_GET['post'])) { $page = Page::find_by_id(4); } else { $page = Page::find_by_id(1); } $post = isset($_GET['post']) ? Blogpost::find_by_slug($_GET['post']) : false; $front = $page->id == 1 ? true : false; $buildblog = $page->id == 4 ? true : false; $eventpage = $page->id == 42 ? true : false; // Setting up content edit variables $edit = isset($_GET['edit']) ? true : false; $preview = isset($_GET['preview']) ? true : false; // Finding page slug value $pageslug = $page->get_slug($loggedIn); ?> <!DOCTYPE html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title> <?php if(!$post) { if($page->id != 1) { echo $page->title." | "; } echo $database->site_name(); } elseif($post) { echo "BuildBlog | ".$post->title; } ?> </title> <link href="<?php echo SITE_URL; ?>/styles/style.css" media="all" rel="stylesheet" /> <?php include(SITE_ROOT."/scripts/myJS.php"); ?> </head> <body class=" <?php if($loggedIn) { echo "logged"; } else { echo "public"; } if($front) { echo " front"; } ?>"> <?php $previewslug = str_replace("&edit", "", $pageslug); ?> <?php if($edit) { echo "<form id='editPageForm' action='?page={$previewslug}&preview' method='post'>"; } ?> <?php if($edit && !$preview) : // Edit original ?> <div id="admin_meta_nav" class="admin_meta_nav"> <ul class="center nolist"> <li class="title">Edit</li> <li class="cancel"><a class="cancel" href="?page=<?php echo $pageslug; ?>&cancel">Cancel</a></li> <li class="save"><input style='position: relative; z-index: 500' class='save' type="submit" name="newpreview" value="Preview" /></li> <li class="publish"><input style='position: relative; z-index: 500' class='publish button' type="submit" name="publishPreview" value="Publish" /></li> </ul> </div> <?php elseif($preview && !$edit) : // Preview your edits ?> <div id="admin_meta_nav" class="admin_meta_nav"> <ul class="center nolist"> <li class="title">Preview</li> <li class="cancel"><a class="cancel" href="?page=<?php echo $pageslug; ?>&cancel">Cancel</a></li> <li class="save"><a class="newpreview" href="?page=<?php echo $pageslug; ?>&preview&edit">Continue Editing</a></li> <li class="publish"><a class="publish" href="?page=<?php echo $pageslug; ?>&publishLastPreview">Publish</a></li> </ul> </div> <?php elseif($preview && $edit) : // Return to preview and continue editing ?> <div id="admin_meta_nav" class="admin_meta_nav"> <ul class="center nolist"> <li class="title">Edit Again</li> <li class="cancel"><a class="cancel" href="?page=<?php echo $pageslug; ?>&cancel">Cancel</a></li> <li class="save"><input style='position: relative; z-index: 500' class='save button' type="submit" name="newpreview" value="Preview" /></li> <li class="publish"><input style='position: relative; z-index: 500' class='publish button' type="submit" name="publishPreview" value="Publish" /></li> </ul> </div> <?php else : ?> <div id="meta_nav" class="meta_nav"> <ul class="center nolist"> <li><a href="login.php?logout">Logout</a></li> <li><a href="<?php echo SITE_URL; ?>/admin">Admin</a></li> <li><a href="<?php if($front) { echo "admin/?admin=frontpage"; } elseif($event || $eventpage) { echo "admin/?admin=events"; } elseif($buildblog) { if($post) { echo "admin/editpost.php?post={$post->id}"; } else { echo "admin/?admin=blog"; } } else { echo "?page=".$pageslug."&edit"; } ?>">Edit Mode</a></li> <li><a href="<?php echo SITE_URL; ?>/?page=donate">Donate</a></li> <li><a href="<?php echo SITE_URL; ?>/?page=calendar">Calendar</a></li> </ul> <div class="clear"></div> </div> <?php endif; ?> <div id="public_meta_nav" class="public_meta_nav"> <div class="center"> <ul class="nolist"> <li><a href="<?php echo SITE_URL; ?>/?page=donate">Donate</a></li> <li><a href="<?php echo SITE_URL; ?>/?page=calendar">Calendar</a></li> </ul> <div class="clear"></div> </div> </div> * Main Navigation Section, as seen in screenshots above, starts here ** <div class="header"> <div class="center"> <a class="front_logo" href="<?php echo SITE_URL; ?>"><?php echo $database->site_name(); ?></a> <ul class="nolist main_nav"> <?php $tops = Page::get_top_pages(); $topcount = 1; foreach($tops as $top) { $current = $top->id == $topID ? true : false; $title = $top->title == "Front Page" ?

ie7 innerhtml strange display problem

- by thoraniann

Hello, I am having a strange problem with ie7 (ie8 in compatibility mode). I have div containers where I am updating values using javascript innhtml to update the values. This works fine in Firefox and ie8. In ie7 the values do not update but if a click on the values and highlight them then they update, also if a change the height of the browser then on the next update the values get updated correctly. I have figured out that if I change the position property of the outer div container from relative to static then the updates work correctly. The page can be viewed here http://islendingasogur.net/test/webmap_html_test.html In internet explorer 8 with compatibility turned on you can see that the timestamp in the gray box only gets updated one time, after that you see no changes. The timestamp in the lower right corner gets updated every 10 seconds. But if you highlight the text in the gray box then the updated timestamp values appears! Here is the page: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html;

I have only seen this error in ie8 with compatibility turned on. If anybody has seen this before and has a fix, I would be very grateful. Thanks.

xutility file???

- by user574290

Hi all. I'm trying to use c code with opencv in face detection and counting, but I cannot build the source. I am trying to compile my project and I am having a lot of problems with a line in the xutility file. the error message show that it error with xutility file.

Unpacking a ZTE ZXV10 H108L router firmware

- by v3ng3ful

I binwalked a firmware of a ZTE ZXV10 H108L, and got some encouraging results of uImage uboot, and LZMA compression, as well as a Squashfs 3.0 LZMA compressed filesystem. 256 0x100 uImage header, header size: 64 bytes, header CRC: 0xE70BCBB9, created: Thu Nov 10 04:54:54 2011, image size: 804172 bytes, Data Address: 0x80002000, Entry Point: 0x80266000, data CRC: 0x6EFE90F1, OS: Linux, CPU: MIPS, image type: OS Kernel Image, compression type: lzma, image name: MIPS Linux-2.6.20 320 0x140 LZMA compressed data, properties: 0x5D, dictionary size: 8388608 bytes, uncompressed size: 2637958 bytes 851968 0xD0000 Squashfs filesystem, big endian, lzma signature, version 3.0, size: 2543403 bytes, 632 inodes, blocksize: 65536 bytes, created: Thu Nov 10 04:56:12 2011 Now what I did is, to test several portions of the file (320byte-end, 851968byte-end, and many more) using dd, and trying with certain tools to uncompress/unpack the filesystem of the firmware. After some digging I found out the best tool to do this is the firmware_mod_kit, that understands a squashfs-lzma v3 filesystem. Although I ended up really frustrated as unsquashfs-lzma v3 reported a cold "zlib::uncompress failed, unknown error -3". Do you have any ideas? Could it be that, the firmware is corrupted on purpose to discourage attempts like this? Router file Thanks

Networking stopped working on Ubuntu

- by 1337Rooster

I installed Ubuntu 10.04 through the Wubi installer (Funny, I installed it today and thought I would have gotten 10.10). I had a network connection and everything was working fine. I rebooted my coumputer a couple of times and then suddenly, I could not connect to the network and when I click the wireless/networking icon it says "Networking Disabled". I reinstalled Ubuntu and the problem went away. After a few reboots the problem returned. I have tried restarting to see if it would come back as well as a few other things listed below. Any other suggestions would be appreciated. Tried to restart networking via /etc/init.d/networking: amato@ubuntu:~$ sudo /etc/init.d/networking restart * Reconfiguring network interfaces... Ignoring unknown interface eth0=eth0. [ OK ] Tried to stop and start it: amato@ubuntu:~$ sudo /etc/init.d/networking stop * Deconfiguring network interfaces... [ OK ] amato@ubuntu:~$ amato@ubuntu:~$ sudo /etc/init.d/networking start Rather than invoking init scripts through /etc/init.d, use the service(8) utility, e.g. service networking start Since the script you are attempting to invoke has been converted to an Upstart job, you may also use the start(8) utility, e.g. start networking networking stop/waiting Tried start networking: amato@ubuntu:~$ start networking start: Rejected send message, 1 matched rules; type="method_call", sender=":1.58" (uid=1000 pid=2241 comm="start) interface="com.ubuntu.Upstart0_6.Job" member="Start" error name="(unset)" requested_reply=0 destination="com.ubuntu.Upstart" (uid=0 pid=1 comm="/sbin/init")) amato@ubuntu:~$ sudo start networking networking stop/waiting Tried service networking restart: amato@ubuntu:~$ service networking restart restart: Rejected send message, 1 matched rules; type="method_call", sender=":1.60" (uid=1000 pid=2248 comm="restart) interface="com.ubuntu.Upstart0_6.Job" member="Restart" error name="(unset)" requested_reply=0 destination="com.ubuntu.Upstart" (uid=0 pid=1 comm="/sbin/init")) amato@ubuntu:~$ sudo service networking restart restart: Unknown instance: Here are the contents of my /etc/network/interfaces. auto lo iface lo inet loopback I even tried to modify it to this (based on something I read, online, not sure if I was doing the right thing here).

SQL SERVER – Introduction to Extended Events – Finding Long Running Queries

- by pinaldave

The job of an SQL Consultant is very interesting as always. The month before, I was busy doing query optimization and performance tuning projects for our clients, and this month, I am busy delivering my performance in Microsoft SQL Server 2005/2008 Query Optimization and & Performance Tuning Course. I recently read white paper about Extended Event by SQL Server MVP Jonathan Kehayias. You can read the white paper here: Using SQL Server 2008 Extended Events. I also read another appealing chapter by Jonathan in the book, SQLAuthority Book Review – Professional SQL Server 2008 Internals and Troubleshooting. After reading these excellent notes by Jonathan, I decided to upgrade my course and include Extended Event as one of the modules. This week, I have delivered Extended Events session two times and attendees really liked the said course. They really think Extended Events is one of the most powerful tools available. Extended Events can do many things. I suggest that you read the white paper I mentioned to learn more about this tool. Instead of writing a long theory, I am going to write a very quick script for Extended Events. This event session captures all the longest running queries ever since the event session was started. One of the many advantages of the Extended Events is that it can be configured very easily and it is a robust method to collect necessary information in terms of troubleshooting. There are many targets where you can store the information, which include XML file target, which I really like. In the following Events, we are writing the details of the event at two locations: 1) Ringer Buffer; and 2) XML file. It is not necessary to write at both places, either of the two will do. -- Extended Event for finding *long running query* IF EXISTS(SELECT * FROM sys.server_event_sessions WHERE name='LongRunningQuery') DROP EVENT SESSION LongRunningQuery ON SERVER GO -- Create Event CREATE EVENT SESSION LongRunningQuery ON SERVER -- Add event to capture event ADD EVENT sqlserver.sql_statement_completed ( -- Add action - event property ACTION (sqlserver.sql_text, sqlserver.tsql_stack) -- Predicate - time 1000 milisecond WHERE sqlserver.sql_statement_completed.duration > 1000 ) -- Add target for capturing the data - XML File ADD TARGET package0.asynchronous_file_target( SET filename='c:\LongRunningQuery.xet', metadatafile='c:\LongRunningQuery.xem'), -- Add target for capturing the data - Ring Bugger ADD TARGET package0.ring_buffer (SET max_memory = 4096) WITH (max_dispatch_latency = 1 seconds) GO -- Enable Event ALTER EVENT SESSION LongRunningQuery ON SERVER STATE=START GO -- Run long query (longer than 1000 ms) SELECT * FROM AdventureWorks.Sales.SalesOrderDetail ORDER BY UnitPriceDiscount DESC GO -- Stop the event ALTER EVENT SESSION LongRunningQuery ON SERVER STATE=STOP GO -- Read the data from Ring Buffer SELECT CAST(dt.target_data AS XML) AS xmlLockData FROM sys.dm_xe_session_targets dt JOIN sys.dm_xe_sessions ds ON ds.Address = dt.event_session_address JOIN sys.server_event_sessions ss ON ds.Name = ss.Name WHERE dt.target_name = 'ring_buffer' AND ds.Name = 'LongRunningQuery' GO -- Read the data from XML File SELECT event_data_XML.value('(event/data[1])[1]','VARCHAR(100)') AS Database_ID, event_data_XML.value('(event/data[2])[1]','INT') AS OBJECT_ID, event_data_XML.value('(event/data[3])[1]','INT') AS object_type, event_data_XML.value('(event/data[4])[1]','INT') AS cpu, event_data_XML.value('(event/data[5])[1]','INT') AS duration, event_data_XML.value('(event/data[6])[1]','INT') AS reads, event_data_XML.value('(event/data[7])[1]','INT') AS writes, event_data_XML.value('(event/action[1])[1]','VARCHAR(512)') AS sql_text, event_data_XML.value('(event/action[2])[1]','VARCHAR(512)') AS tsql_stack, CAST(event_data_XML.value('(event/action[2])[1]','VARCHAR(512)') AS XML).value('(frame/@handle)[1]','VARCHAR(50)') AS handle FROM ( SELECT CAST(event_data AS XML) event_data_XML, * FROM sys.fn_xe_file_target_read_file ('c:\LongRunningQuery*.xet', 'c:\LongRunningQuery*.xem', NULL, NULL)) T GO -- Clean up. Drop the event DROP EVENT SESSION LongRunningQuery ON SERVER GO Just run the above query, afterwards you will find following result set. This result set contains the query that was running over 1000 ms. In our example, I used the XML file, and it does not reset when SQL services or computers restarts (if you are using DMV, it will reset when SQL services restarts). This event session can be very helpful for troubleshooting. Let me know if you want me to write more about Extended Events. I am totally fascinated with this feature, so I’m planning to acquire more knowledge about it so I can determine its other usages.

SCCM Report to identify machines with 64-bit capable hardware

- by GAThrawn

Currently looking at deployment options for Windows 7. One of the questions we're looking into is 32 bit vs 63 bit. I'm trying to run a SCCM report against our estate to identify which machines are 64-bit capable (whether or not they're currently running a 64-bit OS). There seem to be a few resources out on the net for this (here, here and here) but none of them seem to work right on machines running 32-bit Windows XP. 32-bit XP machines seem to always report that they're running on 32-bit hardware. The query I'm currently running is: select sys.netbios_name0, sys.Operating_System_Name_and0 as OperatingSystem, case when pr.addresswidth0=64 then '64bit OS' when pr.addresswidth0=32 then '32bit OS' end as [Operating System Type], case when pr.DataWidth0=64 then '64bit Processor' when pr.DataWidth0=32 then '32bit Processor' end as [Processor Type], case when pr.addresswidth0=32 and pr.DataWidth0=64 then 'YES' end as [32-bit OS on x64 processor] from v_r_system sys join v_gs_processor pr on sys.resourceid=pr.resourceid I've also tried this, which reports all "Windows XP Professional" systems are on "X86-based PC", not x64 based even though a number of them definitely are: select OS.Caption0, CS.SystemType0, Count(*) from dbo.v_GS_COMPUTER_SYSTEM CS Left Outer Join dbo.v_GS_OPERATING_SYSTEM OS on CS.ResourceID = OS.ResourceId Group by OS.Caption0, CS.SystemType0 Order by OS.Caption0, CS.SystemType0 For instance we have a set of Dell Latitude E4200 laptops. Some of these are running 32-bit Windows XP SP3, some of them are running 32-bit Windows 7, some are running 64-bit Windows 7. All the laptops are identical, having come from the same order. Out of these the Windows 7 (32 and 64-bit) report that the hardware is 64-bit capable, and the Windows XP machines report that they're only 32-bit capable. Does anyone know if there's another value I can query to get the hardware's capabilities correctly on XP, or is there a hotfix that will get it reporting the correct info?

Zabbix Log Monitoring - Duplicate alerts

- by ArunS

I am configured Zabbix to monitor my Jboss Server logs for Erros and exclude some know errors. This setup is working with one issue. Zabbix will send me alerts when there is a new "ERROR" entry in the log file. But sometimes I get multiple alerts for the same event. For example, I got 5 alerts with the same time stamp "2012-06-25 07:55:56,864 ERROR". The duplicate alerts count is not constant, sometimes I get 2 sometimes 5 or 11. I checked the Monitoring Latest data in the GUI, and found that there is no duplicate entries. I have given my configuration of the log monitoring below. I am using latest version of zabbix server(2.0) Item configuration: Description: Server Error Monitoring. Key: log["/SERVER/jboss/jboss-5/server/ps/log/server.log","ERROR",UTF-8,200,skip] Type: Zabbix Agent (Active) Type of information: Log Interval :30 Trigger configuration: Description: Found Error in Server Log.

LiteSpeed enable Access-Control-Allow-Origin (no response header on CORS request)

- by Joe Coder Guy

Seriously, I can't find a single page discussing this for litespeed. Using this format in the htaccess "Header set Access-Control-Allow-Origin http://aSite.com" (and https) sends the setting in the http response header, but I still get the "XMLHttpRequest cannot load https://aSite.com/aFile.php. Origin aSite.com is not allowed by Access-Control-Allow-Origin" error when trying to access https from http origin. Also, I receive no response header for https, only that message shows up in Chrome. Is the server still blocking it even though I've sent the proper headers? I read elsewhere that it helps to add these terms Access-Control-Allow-Headers X-Requested-With Access-Control-Allow-Methods OPTIONS, GET, POST Access-Control-Allow-Headers Content-Type, Depth, User-Agent, X-File-Size, X-Requested-With, If-Modified-Since, X-File-Name, Cache-Control but I don't see these in my headers. Using these, my PHP files aren't even reached (because they register no errors or anything), so it looks like it comes from the server only, but what do I know. Thanks in advance! Update Since no response header, Prashant seems to suggest it's a server issue in his error since it worked on another server. http://stackoverflow.com/questions/11953132/no-response-obtained-while-implementing-cors Anyone know how to flip this switch? Headers work now Bad litespeed format. Should look like this. Still being denied though. Header set Access-Control-Allow-Headers X-Requested-With Header set Access-Control-Allow-Methods OPTIONS Header set Access-Control-Allow-Methods GET Header set Access-Control-Allow-Methods POST Header set Access-Control-Allow-Headers Content-Type Header set Access-Control-Allow-Headers Depth Header set Access-Control-Allow-Headers User-Agent Header set Access-Control-Allow-Headers X-File-Size Header set Access-Control-Allow-Headers X-Requested-With Header set Access-Control-Allow-Headers If-Modified-Since Header set Access-Control-Allow-Headers X-File-Name Header set Access-Control-Allow-Headers Cache-Control

Juniper EX3300 routing issue

- by Richard Whitman

The routing on my Juniper EX3300 does not seem to be working. My ISP's gateway is at xx.xx.xx.xx. And I have the following in the configuration: routing-options { static { route 0.0.0.0/0 { next-hop xx.xx.xx.xx; retain; } } } I can ping to my ISP's gateway from the switch. However, I can NOT ping to any other IP. When I do a traceroute (to Google.com's IP). This is what I get: traceroute to 74.125.224.69 (74.125.224.69), 30 hops max, 40 byte packets traceroute: sendto: No route to host 1 traceroute: wrote 74.125.224.69 40 chars, ret=-1 *traceroute: sendto: No route to host Do I need to enable any protocols?

NDepend tool – Why every developer working with Visual Studio.NET must try it!

- by hajan

In the past two months, I have had a chance to test the capabilities and features of the amazing NDepend tool designed to help you make your .NET code better, more beautiful and achieve high code quality. In other words, this tool will definitely help you harmonize your code. I mean, you’ve probably heard about Chaos Theory. Experienced developers and architects are already advocates of the programming chaos that happens when working with complex project architecture, the matrix of relationships between objects which simply even if you are the one who have written all that code, you know how hard is to visualize everything what does the code do. When the application get more and more complex, you will start missing a lot of details in your code… NDepend will help you visualize all the details on a clever way that will help you make smart moves to make your code better. The NDepend tool supports many features, such as: Code Query Language – which will help you write custom rules and query your own code! Imagine, you want to find all your methods which have more than 100 lines of code :)! That’s something simple! However, I will dig much deeper in one of my next blogs which I’m going to dedicate to the NDepend’s CQL (Code Query Language) Architecture Visualization – You are an architect and want to visualize your application’s architecture? I’m thinking how many architects will be really surprised from their architectures since NDepend shows your whole architecture showing each piece of it. NDepend will show you how your code is structured. It shows the architecture in graphs, but if you have very complex architecture, you can see it in Dependency Matrix which is more suited to display large architecture Code Metrics – Using NDepend’s panel, you can see the code base according to Code Metrics. You can do some additional filtering, like selecting the top code elements ordered by their current code metric value. You can use the CQL language for this purpose too. Smart Search – NDepend has great searching ability, which is again based on the CQL (Code Query Language). However, you have some options to search using dropdown lists and text boxes and it will generate the appropriate CQL code on fly. Moreover, you can modify the CQL code if you want it to fit some more advanced searching tasks. Compare Builds and Code Difference – NDepend will also help you compare previous versions of your code with the current one at one of the most clever ways I’ve seen till now. Create Custom Rules – using CQL you can create custom rules and let NDepend warn you on each build if you break a rule Reporting – NDepend can automatically generate reports with detailed stats, graph representation, dependency matrixes and some additional advanced reporting features that will simply explain you everything related to your application’s code, architecture and what you’ve done. And that’s not all. As I’ve seen, there are many other features that NDepend supports. I will dig more in the upcoming days and will blog more about it. The team who built the NDepend have also created good documentation, which you can find on the NDepend website. On their website, you can also find some good videos that will help you get started quite fast. It’s easy to install and what is very important it is fully integrated with Visual Studio. To get you started, you can watch the following Getting Started Online Demo and Tutorial with explanations and screenshots. If you are interested to know more about how to use the features of this tool, either visit their website or wait for my next blogs where I will show some real examples of using the tool and how it helps make your code better. And the last thing for this blog, I would like to copy one sentence from the NDepend’s home page which says: ‘Hence the software design becomes concrete, code reviews are effective, large refactoring are easy and evolution is mastered.’ Website: www.ndepend.com Getting Started: http://www.ndepend.com/GettingStarted.aspx Features: http://www.ndepend.com/Features.aspx Download: http://www.ndepend.com/NDependDownload.aspx Hope you like it! Please do let me know your feedback by providing comments to my blog post. Kind Regards, Hajan

The Incremental Architect’s Napkin - #5 - Design functions for extensibility and readability

- by Ralf Westphal

Originally posted on: http://geekswithblogs.net/theArchitectsNapkin/archive/2014/08/24/the-incremental-architectrsquos-napkin---5---design-functions-for.aspx The functionality of programs is entered via Entry Points. So what we´re talking about when designing software is a bunch of functions handling the requests represented by and flowing in through those Entry Points. Designing software thus consists of at least three phases: Analyzing the requirements to find the Entry Points and their signatures Designing the functionality to be executed when those Entry Points get triggered Implementing the functionality according to the design aka coding I presume, you´re familiar with phase 1 in some way. And I guess you´re proficient in implementing functionality in some programming language. But in my experience developers in general are not experienced in going through an explicit phase 2. “Designing functionality? What´s that supposed to mean?” you might already have thought. Here´s my definition: To design functionality (or functional design for short) means thinking about… well, functions. You find a solution for what´s supposed to happen when an Entry Point gets triggered in terms of functions. A conceptual solution that is, because those functions only exist in your head (or on paper) during this phase. But you may have guess that, because it´s “design” not “coding”. And here is, what functional design is not: It´s not about logic. Logic is expressions (e.g. +, -, && etc.) and control statements (e.g. if, switch, for, while etc.). Also I consider calling external APIs as logic. It´s equally basic. It´s what code needs to do in order to deliver some functionality or quality. Logic is what´s doing that needs to be done by software. Transformations are either done through expressions or API-calls. And then there is alternative control flow depending on the result of some expression. Basically it´s just jumps in Assembler, sometimes to go forward (if, switch), sometimes to go backward (for, while, do). But calling your own function is not logic. It´s not necessary to produce any outcome. Functionality is not enhanced by adding functions (subroutine calls) to your code. Nor is quality increased by adding functions. No performance gain, no higher scalability etc. through functions. Functions are not relevant to functionality. Strange, isn´t it. What they are important for is security of investment. By introducing functions into our code we can become more productive (re-use) and can increase evolvability (higher unterstandability, easier to keep code consistent). That´s no small feat, however. Evolvable code can hardly be overestimated. That´s why to me functional design is so important. It´s at the core of software development. To sum this up: Functional design is on a level of abstraction above (!) logical design or algorithmic design. Functional design is only done until you get to a point where each function is so simple you are very confident you can easily code it. Functional design an logical design (which mostly is coding, but can also be done using pseudo code or flow charts) are complementary. Software needs both. If you start coding right away you end up in a tangled mess very quickly. Then you need back out through refactoring. Functional design on the other hand is bloodless without actual code. It´s just a theory with no experiments to prove it. But how to do functional design? An example of functional design Let´s assume a program to de-duplicate strings. The user enters a number of strings separated by commas, e.g. a, b, a, c, d, b, e, c, a. And the program is supposed to clear this list of all doubles, e.g. a, b, c, d, e. There is only one Entry Point to this program: the user triggers the de-duplication by starting the program with the string list on the command line C:\>deduplicate "a, b, a, c, d, b, e, c, a" a, b, c, d, e …or by clicking on a GUI button. This leads to the Entry Point function to get called. It´s the program´s main function in case of the batch version or a button click event handler in the GUI version. That´s the physical Entry Point so to speak. It´s inevitable. What then happens is a three step process: Transform the input data from the user into a request. Call the request handler. Transform the output of the request handler into a tangible result for the user. Or to phrase it a bit more generally: Accept input. Transform input into output. Present output. This does not mean any of these steps requires a lot of effort. Maybe it´s just one line of code to accomplish it. Nevertheless it´s a distinct step in doing the processing behind an Entry Point. Call it an aspect or a responsibility - and you will realize it most likely deserves a function of its own to satisfy the Single Responsibility Principle (SRP). Interestingly the above list of steps is already functional design. There is no logic, but nevertheless the solution is described - albeit on a higher level of abstraction than you might have done yourself. But it´s still on a meta-level. The application to the domain at hand is easy, though: Accept string list from command line De-duplicate Present de-duplicated strings on standard output And this concrete list of processing steps can easily be transformed into code:static void Main(string[] args) { var input = Accept_string_list(args); var output = Deduplicate(input); Present_deduplicated_string_list(output); } Instead of a big problem there are three much smaller problems now. If you think each of those is trivial to implement, then go for it. You can stop the functional design at this point. But maybe, just maybe, you´re not so sure how to go about with the de-duplication for example. Then just implement what´s easy right now, e.g.private static string Accept_string_list(string[] args) { return args[0]; } private static void Present_deduplicated_string_list( string[] output) { var line = string.Join(", ", output); Console.WriteLine(line); } Accept_string_list() contains logic in the form of an API-call. Present_deduplicated_string_list() contains logic in the form of an expression and an API-call. And then repeat the functional design for the remaining processing step. What´s left is the domain logic: de-duplicating a list of strings. How should that be done? Without any logic at our disposal during functional design you´re left with just functions. So which functions could make up the de-duplication? Here´s a suggestion: De-duplicate Parse the input string into a true list of strings. Register each string in a dictionary/map/set. That way duplicates get cast away. Transform the data structure into a list of unique strings. Processing step 2 obviously was the core of the solution. That´s where real creativity was needed. That´s the core of the domain. But now after this refinement the implementation of each step is easy again:private static string[] Parse_string_list(string input) { return input.Split(',') .Select(s => s.Trim()) .ToArray(); } private static Dictionary<string,object> Compile_unique_strings(string[] strings) { return strings.Aggregate( new Dictionary<string, object>(), (agg, s) => { agg[s] = null; return agg; }); } private static string[] Serialize_unique_strings( Dictionary<string,object> dict) { return dict.Keys.ToArray(); } With these three additional functions Main() now looks like this:static void Main(string[] args) { var input = Accept_string_list(args); var strings = Parse_string_list(input); var dict = Compile_unique_strings(strings); var output = Serialize_unique_strings(dict); Present_deduplicated_string_list(output); } I think that´s very understandable code: just read it from top to bottom and you know how the solution to the problem works. It´s a mirror image of the initial design: Accept string list from command line Parse the input string into a true list of strings. Register each string in a dictionary/map/set. That way duplicates get cast away. Transform the data structure into a list of unique strings. Present de-duplicated strings on standard output You can even re-generate the design by just looking at the code. Code and functional design thus are always in sync - if you follow some simple rules. But about that later. And as a bonus: all the functions making up the process are small - which means easy to understand, too. So much for an initial concrete example. Now it´s time for some theory. Because there is method to this madness ;-) The above has only scratched the surface. Introducing Flow Design Functional design starts with a given function, the Entry Point. Its goal is to describe the behavior of the program when the Entry Point is triggered using a process, not an algorithm. An algorithm consists of logic, a process on the other hand consists just of steps or stages. Each processing step transforms input into output or a side effect. Also it might access resources, e.g. a printer, a database, or just memory. Processing steps thus can rely on state of some sort. This is different from Functional Programming, where functions are supposed to not be stateful and not cause side effects.[1] In its simplest form a process can be written as a bullet point list of steps, e.g. Get data from user Output result to user Transform data Parse data Map result for output Such a compilation of steps - possibly on different levels of abstraction - often is the first artifact of functional design. It can be generated by a team in an initial design brainstorming. Next comes ordering the steps. What should happen first, what next etc.? Get data from user Parse data Transform data Map result for output Output result to user That´s great for a start into functional design. It´s better than starting to code right away on a given function using TDD. Please get me right: TDD is a valuable practice. But it can be unnecessarily hard if the scope of a functionn is too large. But how do you know beforehand without investing some thinking? And how to do this thinking in a systematic fashion? My recommendation: For any given function you´re supposed to implement first do a functional design. Then, once you´re confident you know the processing steps - which are pretty small - refine and code them using TDD. You´ll see that´s much, much easier - and leads to cleaner code right away. For more information on this approach I call “Informed TDD” read my book of the same title. Thinking before coding is smart. And writing down the solution as a bunch of functions possibly is the simplest thing you can do, I´d say. It´s more according to the KISS (Keep It Simple, Stupid) principle than returning constants or other trivial stuff TDD development often is started with. So far so good. A simple ordered list of processing steps will do to start with functional design. As shown in the above example such steps can easily be translated into functions. Moving from design to coding thus is simple. However, such a list does not scale. Processing is not always that simple to be captured in a list. And then the list is just text. Again. Like code. That means the design is lacking visuality. Textual representations need more parsing by your brain than visual representations. Plus they are limited in their “dimensionality”: text just has one dimension, it´s sequential. Alternatives and parallelism are hard to encode in text. In addition the functional design using numbered lists lacks data. It´s not visible what´s the input, output, and state of the processing steps. That´s why functional design should be done using a lightweight visual notation. No tool is necessary to draw such designs. Use pen and paper; a flipchart, a whiteboard, or even a napkin is sufficient. Visualizing processes The building block of the functional design notation is a functional unit. I mostly draw it like this: Something is done, it´s clear what goes in, it´s clear what comes out, and it´s clear what the processing step requires in terms of state or hardware. Whenever input flows into a functional unit it gets processed and output is produced and/or a side effect occurs. Flowing data is the driver of something happening. That´s why I call this approach to functional design Flow Design. It´s about data flow instead of control flow. Control flow like in algorithms is of no concern to functional design. Thinking about control flow simply is too low level. Once you start with control flow you easily get bogged down by tons of details. That´s what you want to avoid during design. Design is supposed to be quick, broad brush, abstract. It should give overview. But what about all the details? As Robert C. Martin rightly said: “Programming is abot detail”. Detail is a matter of code. Once you start coding the processing steps you designed you can worry about all the detail you want. Functional design does not eliminate all the nitty gritty. It just postpones tackling them. To me that´s also an example of the SRP. Function design has the responsibility to come up with a solution to a problem posed by a single function (Entry Point). And later coding has the responsibility to implement the solution down to the last detail (i.e. statement, API-call). TDD unfortunately mixes both responsibilities. It´s just coding - and thereby trying to find detailed implementations (green phase) plus getting the design right (refactoring). To me that´s one reason why TDD has failed to deliver on its promise for many developers. Using functional units as building blocks of functional design processes can be depicted very easily. Here´s the initial process for the example problem: For each processing step draw a functional unit and label it. Choose a verb or an “action phrase” as a label, not a noun. Functional design is about activities, not state or structure. Then make the output of an upstream step the input of a downstream step. Finally think about the data that should flow between the functional units. Write the data above the arrows connecting the functional units in the direction of the data flow. Enclose the data description in brackets. That way you can clearly see if all flows have already been specified. Empty brackets mean “no data is flowing”, but nevertheless a signal is sent. A name like “list” or “strings” in brackets describes the data content. Use lower case labels for that purpose. A name starting with an upper case letter like “String” or “Customer” on the other hand signifies a data type. If you like, you also can combine descriptions with data types by separating them with a colon, e.g. (list:string) or (strings:string[]). But these are just suggestions from my practice with Flow Design. You can do it differently, if you like. Just be sure to be consistent. Flows wired-up in this manner I call one-dimensional (1D). Each functional unit just has one input and/or one output. A functional unit without an output is possible. It´s like a black hole sucking up input without producing any output. Instead it produces side effects. A functional unit without an input, though, does make much sense. When should it start to work? What´s the trigger? That´s why in the above process even the first processing step has an input. If you like, view such 1D-flows as pipelines. Data is flowing through them from left to right. But as you can see, it´s not always the same data. It get´s transformed along its passage: (args) becomes a (list) which is turned into (strings). The Principle of Mutual Oblivion A very characteristic trait of flows put together from function units is: no functional units knows another one. They are all completely independent of each other. Functional units don´t know where their input is coming from (or even when it´s gonna arrive). They just specify a range of values they can process. And they promise a certain behavior upon input arriving. Also they don´t know where their output is going. They just produce it in their own time independent of other functional units. That means at least conceptually all functional units work in parallel. Functional units don´t know their “deployment context”. They now nothing about the overall flow they are place in. They are just consuming input from some upstream, and producing output for some downstream. That makes functional units very easy to test. At least as long as they don´t depend on state or resources. I call this the Principle of Mutual Oblivion (PoMO). Functional units are oblivious of others as well as an overall context/purpose. They are just parts of a whole focused on a single responsibility. How the whole is built, how a larger goal is achieved, is of no concern to the single functional units. By building software in such a manner, functional design interestingly follows nature. Nature´s building blocks for organisms also follow the PoMO. The cells forming your body do not know each other. Take a nerve cell “controlling” a muscle cell for example:[2] The nerve cell does not know anything about muscle cells, let alone the specific muscel cell it is “attached to”. Likewise the muscle cell does not know anything about nerve cells, let a lone a specific nerve cell “attached to” it. Saying “the nerve cell is controlling the muscle cell” thus only makes sense when viewing both from the outside. “Control” is a concept of the whole, not of its parts. Control is created by wiring-up parts in a certain way. Both cells are mutually oblivious. Both just follow a contract. One produces Acetylcholine (ACh) as output, the other consumes ACh as input. Where the ACh is going, where it´s coming from neither cell cares about. Million years of evolution have led to this kind of division of labor. And million years of evolution have produced organism designs (DNA) which lead to the production of these different cell types (and many others) and also to their co-location. The result: the overall behavior of an organism. How and why this happened in nature is a mystery. For our software, though, it´s clear: functional and quality requirements needs to be fulfilled. So we as developers have to become “intelligent designers” of “software cells” which we put together to form a “software organism” which responds in satisfying ways to triggers from it´s environment. My bet is: If nature gets complex organisms working by following the PoMO, who are we to not apply this recipe for success to our much simpler “machines”? So my rule is: Wherever there is functionality to be delivered, because there is a clear Entry Point into software, design the functionality like nature would do it. Build it from mutually oblivious functional units. That´s what Flow Design is about. In that way it´s even universal, I´d say. Its notation can also be applied to biology: Never mind labeling the functional units with nouns. That´s ok in Flow Design. You´ll do that occassionally for functional units on a higher level of abstraction or when their purpose is close to hardware. Getting a cockroach to roam your bedroom takes 1,000,000 nerve cells (neurons). Getting the de-duplication program to do its job just takes 5 “software cells” (functional units). Both, though, follow the same basic principle. Translating functional units into code Moving from functional design to code is no rocket science. In fact it´s straightforward. There are two simple rules: Translate an input port to a function. Translate an output port either to a return statement in that function or to a function pointer visible to that function. The simplest translation of a functional unit is a function. That´s what you saw in the above example. Functions are mutually oblivious. That why Functional Programming likes them so much. It makes them composable. Which is the reason, nature works according to the PoMO. Let´s be clear about one thing: There is no dependency injection in nature. For all of an organism´s complexity no DI container is used. Behavior is the result of smooth cooperation between mutually oblivious building blocks. Functions will often be the adequate translation for the functional units in your designs. But not always. Take for example the case, where a processing step should not always produce an output. Maybe the purpose is to filter input. Here the functional unit consumes words and produces words. But it does not pass along every word flowing in. Some words are swallowed. Think of a spell checker. It probably should not check acronyms for correctness. There are too many of them. Or words with no more than two letters. Such words are called “stop words”. In the above picture the optionality of the output is signified by the astrisk outside the brackets. It means: Any number of (word) data items can flow from the functional unit for each input data item. It might be none or one or even more. This I call a stream of data. Such behavior cannot be translated into a function where output is generated with return. Because a function always needs to return a value. So the output port is translated into a function pointer or continuation which gets passed to the subroutine when called:[3]void filter_stop_words( string word, Action<string> onNoStopWord) { if (...check if not a stop word...) onNoStopWord(word); } If you want to be nitpicky you might call such a function pointer parameter an injection. And technically you´re right. Conceptually, though, it´s not an injection. Because the subroutine is not functionally dependent on the continuation. Firstly continuations are procedures, i.e. subroutines without a return type. Remember: Flow Design is about unidirectional data flow. Secondly the name of the formal parameter is chosen in a way as to not assume anything about downstream processing steps. onNoStopWord describes a situation (or event) within the functional unit only. Translating output ports into function pointers helps keeping functional units mutually oblivious in cases where output is optional or produced asynchronically. Either pass the function pointer to the function upon call. Or make it global by putting it on the encompassing class. Then it´s called an event. In C# that´s even an explicit feature.class Filter { public void filter_stop_words( string word) { if (...check if not a stop word...) onNoStopWord(word); } public event Action<string> onNoStopWord; } When to use a continuation and when to use an event dependens on how a functional unit is used in flows and how it´s packed together with others into classes. You´ll see examples further down the Flow Design road. Another example of 1D functional design Let´s see Flow Design once more in action using the visual notation. How about the famous word wrap kata? Robert C. Martin has posted a much cited solution including an extensive reasoning behind his TDD approach. So maybe you want to compare it to Flow Design. The function signature given is:string WordWrap(string text, int maxLineLength) {...} That´s not an Entry Point since we don´t see an application with an environment and users. Nevertheless it´s a function which is supposed to provide a certain functionality. The text passed in has to be reformatted. The input is a single line of arbitrary length consisting of words separated by spaces. The output should consist of one or more lines of a maximum length specified. If a word is longer than a the maximum line length it can be split in multiple parts each fitting in a line. Flow Design Let´s start by brainstorming the process to accomplish the feat of reformatting the text. What´s needed? Words need to be assembled into lines Words need to be extracted from the input text The resulting lines need to be assembled into the output text Words too long to fit in a line need to be split Does sound about right? I guess so. And it shows a kind of priority. Long words are a special case. So maybe there is a hint for an incremental design here. First let´s tackle “average words” (words not longer than a line). Here´s the Flow Design for this increment: The the first three bullet points turned into functional units with explicit data added. As the signature requires a text is transformed into another text. See the input of the first functional unit and the output of the last functional unit. In between no text flows, but words and lines. That´s good to see because thereby the domain is clearly represented in the design. The requirements are talking about words and lines and here they are. But note the asterisk! It´s not outside the brackets but inside. That means it´s not a stream of words or lines, but lists or sequences. For each text a sequence of words is output. For each sequence of words a sequence of lines is produced. The asterisk is used to abstract from the concrete implementation. Like with streams. Whether the list of words gets implemented as an array or an IEnumerable is not important during design. It´s an implementation detail. Does any processing step require further refinement? I don´t think so. They all look pretty “atomic” to me. And if not… I can always backtrack and refine a process step using functional design later once I´ve gained more insight into a sub-problem. Implementation The implementation is straightforward as you can imagine. The processing steps can all be translated into functions. Each can be tested easily and separately. Each has a focused responsibility. And the process flow becomes just a sequence of function calls: Easy to understand. It clearly states how word wrapping works - on a high level of abstraction. And it´s easy to evolve as you´ll see. Flow Design - Increment 2 So far only texts consisting of “average words” are wrapped correctly. Words not fitting in a line will result in lines too long. Wrapping long words is a feature of the requested functionality. Whether it´s there or not makes a difference to the user. To quickly get feedback I decided to first implement a solution without this feature. But now it´s time to add it to deliver the full scope. Fortunately Flow Design automatically leads to code following the Open Closed Principle (OCP). It´s easy to extend it - instead of changing well tested code. How´s that possible? Flow Design allows for extension of functionality by inserting functional units into the flow. That way existing functional units need not be changed. The data flow arrow between functional units is a natural extension point. No need to resort to the Strategy Pattern. No need to think ahead where extions might need to be made in the future. I just “phase in” the remaining processing step: Since neither Extract words nor Reformat know of their environment neither needs to be touched due to the “detour”. The new processing step accepts the output of the existing upstream step and produces data compatible with the existing downstream step. Implementation - Increment 2 A trivial implementation checking the assumption if this works does not do anything to split long words. The input is just passed on: Note how clean WordWrap() stays. The solution is easy to understand. A developer looking at this code sometime in the future, when a new feature needs to be build in, quickly sees how long words are dealt with. Compare this to Robert C. Martin´s solution:[4] How does this solution handle long words? Long words are not even part of the domain language present in the code. At least I need considerable time to understand the approach. Admittedly the Flow Design solution with the full implementation of long word splitting is longer than Robert C. Martin´s. At least it seems. Because his solution does not cover all the “word wrap situations” the Flow Design solution handles. Some lines would need to be added to be on par, I guess. But even then… Is a difference in LOC that important as long as it´s in the same ball park? I value understandability and openness for extension higher than saving on the last line of code. Simplicity is not just less code, it´s also clarity in design. But don´t take my word for it. Try Flow Design on larger problems and compare for yourself. What´s the easier, more straightforward way to clean code? And keep in mind: You ain´t seen all yet ;-) There´s more to Flow Design than described in this chapter. In closing I hope I was able to give you a impression of functional design that makes you hungry for more. To me it´s an inevitable step in software development. Jumping from requirements to code does not scale. And it leads to dirty code all to quickly. Some thought should be invested first. Where there is a clear Entry Point visible, it´s functionality should be designed using data flows. Because with data flows abstraction is possible. For more background on why that´s necessary read my blog article here. For now let me point out to you - if you haven´t already noticed - that Flow Design is a general purpose declarative language. It´s “programming by intention” (Shalloway et al.). Just write down how you think the solution should work on a high level of abstraction. This breaks down a large problem in smaller problems. And by following the PoMO the solutions to those smaller problems are independent of each other. So they are easy to test. Or you could even think about getting them implemented in parallel by different team members. Flow Design not only increases evolvability, but also helps becoming more productive. All team members can participate in functional design. This goes beyon collective code ownership. We´re talking collective design/architecture ownership. Because with Flow Design there is a common visual language to talk about functional design - which is the foundation for all other design activities. PS: If you like what you read, consider getting my ebook “The Incremental Architekt´s Napkin”. It´s where I compile all the articles in this series for easier reading. I like the strictness of Function Programming - but I also find it quite hard to live by. And it certainly is not what millions of programmers are used to. Also to me it seems, the real world is full of state and side effects. So why give them such a bad image? That´s why functional design takes a more pragmatic approach. State and side effects are ok for processing steps - but be sure to follow the SRP. Don´t put too much of it into a single processing step. ? Image taken from www.physioweb.org ? My code samples are written in C#. C# sports typed function pointers called delegates. Action is such a function pointer type matching functions with signature void someName(T t). Other languages provide similar ways to work with functions as first class citizens - even Java now in version 8. I trust you find a way to map this detail of my translation to your favorite programming language. I know it works for Java, C++, Ruby, JavaScript, Python, Go. And if you´re using a Functional Programming language it´s of course a no brainer. ? Taken from his blog post “The Craftsman 62, The Dark Path”. ?

Required Skill Sets Of A Software Architect

The question has been asked as to what is the required skill sets of a software architect. The answer to this is that it truly depends. When I state that it depend, it depends on the organization, industry, and skill sets available on the open market and internally within a company. With open ended skill sets even Napoleon Dynamite could be an architect. Napoleon Dynamite’s Skills Pedro: Have you asked anybody yet? Napoleon Dynamite: No, but who would? I don't even have any good skills. Pedro: What do you mean? Napoleon Dynamite: You know, like nunchuck skills, bow hunting skills, computer hacking skills... Girls only want boyfriends who have great skills. Pedro: Aren't you pretty good at drawing, like animals and warriors and stuff? This example might be a little off base but it does illustrate a point. What are the real required skills of a software architect? In my opinion, an architect needs to demonstrate the knowledge of the following three main skill set categories so that they are successful. General Skill Sets of an Architect Basic Engineering Skills Organizational Skills Interpersonal Skills Basic Engineering Skills are a very large part of what a software architect deal with on a daily bases when designing or updating systems. Think about it, how good would a lead mechanic be if they did not know how to fix or repair cars? They would not be, and that is my point that architects need to have at least some basic skills regarding engineering. The skills listed below are generic in nature because they change from job to job, so in this discussion I am trying to focus more on generalities so that anyone can apply this information to their individual situation. Common Basic Engineering Skills Data Modeling Code Creation Configuration Testing Deployment/Publishing System and Environment Knowledge Organizational Skills If an Architect works for or with an origination then they will need strong organization skills to survive. An architect is no use to a project if the project is missed managed. Additionally, budgets and timelines can really affect a company and their products when established deadlines are repeated not meet. By not meeting these timelines a company is forced to cancel the project and waste all the money and time spent or spend more money until it is completed, if it is ever completed. Common Organizational Skills Project Management Estimation (Cost and Time) Creation and Maintenance of Accepted Standards Interpersonal Skills For me personally Interpersonal skill ranks above the other types of skill sets because an architect can quickly pick up the other two skill sets by communicating with other team/project members so that they are quickly up to speed on a project. Additionally, in order for an architect to manage a project or even derive rough estimates they will more than likely have to consult with others actually working on the code (Programmers/Software Engineers) to get there estimates since they will be the ones actually working on the changes to be implemented. Common Interpersonal Skills Good Communicator Focus on projects success over personal Honors roles within a team Reference: Taylor, R. N., Medvidovic, N., & Dashofy, E. M. (2009).

VirtualBox Issue: virtualbox changed my Computer Name's ip address in Windows

- by suud

I had installed virtualbox 4.2.2 in Windows 7. My Computer Name is: MY-PC My IP address (using ipconfig /all command) is: 192.168.1.101 My IP is dynamic and I set DNS to google dns (8.8.8.8) When I ping MY-PC, I got this result: Pinging MY-PC [192.168.56.1] with 32 bytes of data: Reply from 192.168.56.1: bytes=32 time<1ms TTL=128 Reply from 192.168.56.1: bytes=32 time<1ms TTL=128 Reply from 192.168.56.1: bytes=32 time<1ms TTL=128 Reply from 192.168.56.1: bytes=32 time<1ms TTL=128 My virtualbox was not running and I expected the ip adress of MY-PC is 192.168.1.101, not 192.168.56.1 Then I run command: nbtstat -a MY-PC and I got this result: VirtualBox Host-Only Network: Node IpAddress: [192.168.56.1] Scope Id: [] NetBIOS Remote Machine Name Table Name Type Status --------------------------------------------- MY-PC <00> UNIQUE Registered WORKGROUP <00> GROUP Registered MY-PC <20> UNIQUE Registered MAC Address = 08-00-27-00-60-B3 Local Area Connection: Node IpAddress: [0.0.0.0] Scope Id: [] Host not found.

OpenLDAP mirror mode replication failing with TLS behind a load balancer

directory with 980MB meta data, millions of files, how to delete it? (ext3)

- by Alexandre

Hello, So I'm stuck with this directory: drwxrwxrwx 2 dan users 980M 2010-12-22 18:38 sessions2 The directories contents is small - just millions of tiny little files. I want to wipe it from the filesystem but have been unable to. My first try was: find sessions2 -type f -delete and find sessions2 -type f -print0 | xargs -0 rm -f but had to stop because both caused escalating memory usage. At one point it was using 65% of the system's memory. So I thought (no doubt incorrectly), that it had to do with the fact that dir_index was enabled on the system. Perhaps find was trying to read the entire index into memory? So I did this (foolishly): tune2fs -O^dir_index /dev/xxx Alright, so that should do it. Ran the find command above again and... same thing. Crazy memory usage. I hurriedly ran tune2fs -Odir_index /dev/xxx to reenable dir_index, and ran to Server Fault! 2 questions: 1) How do I get rid of this directory on my live system? I don't care how long it takes, as long as it uses little memory and little CPU. By the way, using nice find ... I was able to reduce CPU usage, so my problem right now is only memory usage. 2) I disabled dir_index for about 20 minutes. No doubt new files were written to the filesystem in the meanwhile. I reenabled dir_index. Does that mean the system will not find the files that were written before dir_index was reenabled since their filenames will be missing from the old indexes? If so and I know these new files aren't important, can I maintain the old indexes? If not, how do I rebuild the indexes? Can it be done on a live system? Thanks!

SQL Server 2005 Merge Replication to SQL Server CE 3.5

- by user33067

Hi, In my organization, we have a SQL Server 2005 database server (DBServer). Users of an application will normally be connected to DBServer, but, occasionally, would like to disconnect and continue their work on a laptop using SQL Server Compact Edition 3.5 (SQLCE). Due to this, we have been looking into using Merge Replication between the DBServer and SQLCE. From what I have read about this process, IIS must be installed on "the server"... yet, I have found no indication to whether this is talking about DBServer or SQLCE. I had assumed the documentation was referring to DBServer and proposed this to our networking staff. That idea was quickly put to rest as it is not our policy to install IIS on an internal server. This is where our SQL Server 2005 web server (WebServer) entered the picture. The idea being that IIS would be installed on WebServer and would be the conduit for DBServer and SQLCE to communicate. This sounded like a good idea at first, until I started looking for documentation on this type of setup. Everything I have been able deals with a DBServer -- SQLCE -- DBServer setup... nothing on DBServer -- WebServer -- SQLCE -- WebServer -- DBServer. Questions: Is going with a 3 server setup ideal? Does anyone have documentation on this type of setup? Does IIS even need to be running on one of the big servers, or can it just run off the laptop with SQLCE on it? (I'd really like this option ;))
