• Python, web log data mining for frequent patterns

  - by descent

  Hello! I need to develop a tool for web log data mining. Having many sequences of urls, requested in a particular user session (retrieved from web-application logs), I need to figure out the patterns of usage and groups (clusters) of users of the website. I am new to Data Mining, and now examining Google a lot. Found some useful info, i.e. querying Frequent Pattern Mining in Web Log Data seems to point to almost exactly similar studies. So my questions are: Are there any python-based tools that do what I need or at least smth similar? Can Orange toolkit be of any help? Can reading the book Programming Collective Intelligence be of any help? What to Google for, what to read, which relatively simple algorithms to use best? I am very limited in time (to around a week), so any help would be extremely precious. What I need is to point me into the right direction and the advice of how to accomplish the task in the shortest time. Thanks in advance!

• Xpath query to select node when attribute does not exist? [closed]

  - by Antoine

  I want to select nodes for which a specific attribute does not exist. I've tried the Not() function, but it doesn't work. Is there a way for this? Example: The following Xpath query: group/msg[not(@owner)] Should retrieve the first node but not the 2nd one. However, both SketchPath (tool to test Xpath queries) and my C# code consider that the 2 nodes are ok. <group> <msg id="EVENTDATA_CCFLOADED_XMLCONTEXT" numericId="14026" translate="False" topicId="302" status="translated" > <text>Context</text> <comment></comment> </msg> <msg id="EVENTDATA_CCFLOADED_XMLCONTEXT_HELP" numericId="14027" translate="False" topicId="302" status="translated" owner="EVENTDATA_CCFLOADED_XMLCONTEXT" > <text>Provides the new data displayed in the Object.</text> <comment></comment> </msg> </group> In fact the Not() function works correctly, it's just that I had other conditions and parentheses weren't set correctly. errare humanum est.

• iPhone app developed with SDK 4.2, requires backward compatibility with iOS 3.1.3 .. easy way?

  - by mrd3650

  I have built an iPhone app with SDK 4.2 however I know also want to make it compatible with iOS 3.1.3. First step was to set the Deployment Target to 3.1.3. It runs fine on the 3.2 Simulator but the app crashes at times since I'm using some methods which are not available in this early SDK. So my qestion is, is there a straight forward way to locate the offending methods/classes I'm using in my project which are not available in 3.1.3 ? (without manually going through each method call and consult with the docs for the SDK availability?) Thanks. UPDATE: I have executed the app on 3.1.3 and attempted to manually test each execution path with the hope of locating all exceptions. This was completed with some level of success. However, what if the application is huge? and there are lots of execution paths? There must be some tool for this scenario. Any thoughts are much appreciated.

• iOS: Best Way to do This w/o Calling Method 32 Times?

  - by user1886754

  I'm currently retrieving the Top 100 Scores for one of my leaderboards the following way: - (void) retrieveTop100Scores { __block int totalScore = 0; GKLeaderboard *myLB = [[GKLeaderboard alloc] init]; myLB.identifier = [Team currentTeam]; myLB.timeScope = GKLeaderboardTimeScopeAllTime; myLB.playerScope = GKLeaderboardPlayerScopeGlobal; myLB.range = NSMakeRange(1, 100); [myLB loadScoresWithCompletionHandler:^(NSArray *scores, NSError *error) { if (error != nil) { NSLog(@"%@", [error localizedDescription]); } if (scores != nil) { for (GKScore *score in scores) { NSLog(@"%lld", score.value); totalScore += score.value; } NSLog(@"Total Score: %d", totalScore); [self loadingDidEnd]; } }]; } The problem is I want to do this for 32 leaderboards. What's the best way of achieving this? Using a third party tool (Game Center Manager), I can get the following line to return a dictionary with leaderboard ID's as keys and the Top 1 highest score as values NSDictionary *highScores = [[GameCenterManager sharedManager] highScoreForLeaderboards:leaderboardIDs]; So my question is, how can I combine those 2 segments of code to pull in the 100 values for each leaderboard, resulting in a dictionary with all of the leaderboard names as keys, and the Total (of each 100 scores) of the leaderboards for values.

• Convert Markdown text to RTF, using Ruby and Pandoc?

  - by niteshade

  Playing with Ruby and Ruby-Pandoc. Seems like a nice tool, if I can get it to work. I'd like to convert some Markdown text (with embedded lists and other fanciness) to Rich Text. Here's the text I'm converting: Title === This is a paragraph. Hallelujah. Here comes a nested list. --- * List item 1 * List item 1.1 * List item 1.2 * List item 2 * List item 2.1 Here's my Ruby code... require 'pandoc-ruby' input = File.read(test.md) converter = PandocRuby.new(input, from: :markdown, to: :rtf) puts converter.convert ... which (after saving the output to a file) produces a document without anything but a title: Here's the code of the RTF file: {\pard \ql \f0 \sa180 \li0 \fi0 \b \fs36 Title\par} {\pard \ql \f0 \sa180 \li0 \fi0 This is a paragraph. Hallelujah.\par} {\pard \ql \f0 \sa180 \li0 \fi0 \b \fs32 Here comes a nested list.\par} {\pard \ql \f0 \sa0 \li360 \fi-360 \bullet \tx360\tab List item 1\par} {\pard \ql \f0 \sa0 \li360 \fi-360 \bullet \tx360\tab List item 1.1\par} {\pard \ql \f0 \sa0 \li360 \fi-360 \bullet \tx360\tab List item 1.2\par} {\pard \ql \f0 \sa0 \li360 \fi-360 \bullet \tx360\tab List item 2\par} {\pard \ql \f0 \sa0 \li360 \fi-360 \bullet \tx360\tab List item 2.1\sa180\par} In addition, even if it did show up in my RTF viewer (Mac TextEdit), the RTF code seems to have lost all list nesting. I don't know how to diagnose this, whether I have not stated necessary header information or something in Ruby-Pandoc. Thanks in advance!

• Inconsistent canvas drawing in Android browser

  - by user2943466

  In putting together a small canvas app I've stumbled across a weird behavior that only seems to occur in the default browser in Android. When drawing to a canvas that has the globalCompositeOperation set to 'destination-out' to act as the 'eraser' tool, Android browser sometimes acts as expected, sometimes does not update the pixels in the canvas at all. the setup: context.clearRect(0,0, canvas.width, canvas.height); context.drawImage(img, 0, 0, canvas.width, canvas.height); context.globalCompositeOperation = 'destination-out'; draw a circle to erase pixels from the canvas: context.fillStyle = '#FFFFFF'; context.beginPath(); context.arc(x,y,25,0,TWO_PI,true); context.fill(); context.closePath(); a small demo to illustrate the issue can be seen here: http://gumbojuice.com/files/source-out/ and the javascript is here: http://gumbojuice.com/files/source-out/js/main.js this has been tested in multiple desktop and mobile browsers and behaves as expected. On Android native browser after refreshing the page sometimes it works, sometimes nothing happens. I've seen other hacks that move the canvas by a pixel in order to force a redraw but this is not an ideal solution.. Thanks all.

• Best way to do client/server validation in ASP.NET in 2010?

  - by punkouter

  First there was the ASP.NET validators and we used them... Then some people on the team did things manually in javascript... Then a bunch of jquery validation libraries came out... Then MVC2 came out with attributes as validators.. I work with apps that have alot of forms with alot of various validation (Some fields needs to be compared with other values in a DB so a postball/ajax call is required) .. Right now I have a mess of ASP.NET custom validators and functions that calculate on the server side as well. Can I get some opinions on the best tool/combination to approach this job that can create the smallest/most elegant code? Pure server side solution? AJAX/Jquery? A certain plugin for jquery? For example, I have 2 dates.. I want to make sure that the 1st date is less than the 2nd date... Are there jquery validators that encapsulate this? My feeling is if I can get jquery plugins to handle half the more basic validation for my that could cut my code in half.

• Doing a global count of an object type (like Users), best practice?

  - by user246114

  Hi, I know keeping global counters is frowned upon in app engine. I am interested in getting some stats though, like once every 24 hours. For example, I'd like to count the number of User objects in the system once every 24 hours. So how do we do this? Do we simply keep a set of admin tool functions which do something like: SELECT FROM com.me.project.server.User; and just see what the size of the returned List is? This is kind of a bummer because the datastore would have to deserialize every single User instance to create the returned list, right? I could optimize this possibly by asking for only the keys to be returned, so the whole User object doesn't have to be deserialized. Then again, a global counter for # of users probably would create too much contention, because there probably won't be hundreds of signups a minute for the service I'm creating. How should we go about doing this? Getting my total number of users once a day is probably a pretty typical operation? Thank you

• how can I make a "downstream only" copy of a file in TFS

  - by jcollum

  I've got this SQL script that needs to exist in two places in source control. I want to have only one real copy of this file and keep a virtual copy of the file in the other solution. One is needed for a unit test and the other for a development tool. The files, should, by definition, always be the same. If they have differences then there's a problem with our process. In Sourcegear I could make a virtual copy of a specific version of a file and keep it somewhere else in the source tree. That doesn't seem to be possible in TFS. Is it possible in SVN? So what are my options here? Branching/merging -- which is what the TFS team says I should be doing here -- means just another step that I have to remember to do. Plus it isn't automatic and I would prefer that this be automated. Is there some way to run an exe on checkin of a specific file? I'm thinking if I could do that then I could do a checkout-edit-checkin of the downstream copy of the file.

• Is there a better way to detab (expand tabs) using Perl?

  - by Uri

  I wanted to detab my source files. (Please, no flame about WHY I wanted to detab my sources. That's not the point :-) I couldn't find a utility to do that. Eclipse didn't do it for me, so I implemented my own. I couldn't fit it into a one liner (-e) program. I came with the following, which did the job just fine. while( <> ) { while( /\t/ ) { s/^(([^\t]{4})*)\t/$1 /; s/^((([^\t]{4})*)[^\t]{1})\t/$1 /; s/^((([^\t]{4})*)[^\t]{2})\t/$1 /; s/^((([^\t]{4})*)[^\t]{3})\t/$1 /; } print; } However, it makes me wonder if Perl - the champion language of processing text - is the right tool. The code doesn't seem very elegant. If I had to detab source that assume tab=8 spaces, the code would look even worse. Specifically because I can think of a deterministic state machine with only 4 states to do the job. I have a feeling that a more elegant solution exists. Am I missing a Perl idiom? In the spirit of TIMTOWTDI I'm curious about the other ways to do it. u.

• Deserializing child elements as attributes of parent

  - by LloydPickering

  I have XML files which I need to deserialize. I used the XSD tool from Visual Studio to create c# object files. the generated classes do deserialize the files except not in the way which I need. I would appreciate any help figuring out how to solve this problem. The child elements named 'data' should be attributes of the parent element 'task'. A shortened example of the XML is below: <task type="Nothing" id="2" taskOnFail="false" > <data value="" name="prerequisiteTasks" /> <data value="" name="exclusionTasks" /> <data value="" name="allowRepeats" /> <task type="Wait for Tasks" id="10" taskOnFail="false" > <data value="" name="prerequisiteTasks" /> <data value="" name="exclusionTasks" /> <data value="" name="allowRepeats" /> </task> <task type="Wait for Tasks" id="10" taskOnFail="false" > <data value="" name="prerequisiteTasks" /> <data value="" name="exclusionTasks" /> <data value="" name="allowRepeats" /> </task> </task> The Class definition I am trying to deserialize to is in the form: public class task { public string prerequisiteTasks {get;set;} public string exclusionTasks {get;set;} public string allowRepeats {get;set;} [System.Xml.Serialization.XmlElementAttribute("task")] public List<task> ChildTasks {get;set;} } The child 'task's are fine, but the generated files put the 'data' elements into an array of data[] rather than as named members of the task class as I need.

• Questions about shifting from mysql to PDO

  - by Scarface

  Hey guys I have recently decided to switch all my current plain mysql queries performed with php mysql_query to PDO style queries to improve performance, portability and security. I just have some quick questions for any experts in this database interaction tool Will it prevent injection if all statements are prepared? (I noticed on php.net it wrote 'however, if other portions of the query are being built up with unescaped input, SQL injection is still possible' I was not exactly sure what this meant). Does this just mean that if all variables are run through a prepare function it is safe, and if some are directly inserted then it is not? Currently I have a connection at the top of my page and queries performed during the rest of the page. I took a look at PDO in more detail and noticed that there is a try and catch procedure for every query involving a connection and the closing of that connection. Is there a straightforward way to connecting and then reusing that connection without having to put everything in a try or constantly repeat the procedure by connecting, querying and closing? Can anyone briefly explain in layman's terms what purpose a set_exception_handler serves? I appreciate any advice from any more experienced individuals.

• Is there a way to sync (two way) tables betwen a mysql server and a local MS Access?

  - by Kailen

  Help me figure out a solution to a (not so unique) problem. My research group has gps devices attached to migratory animals. Every once in a while, a research tech will be within range of an animal and will get the chance to download all the logged points. Each individual spits out a single dbf and new locations are just appended to the end (so the file is just cumulative). These data need to be shared among a research group. Everyone else (besides me) wants to use access, so they can make small edits and prefer that interface. They do not like using MySQL. The solution I came up with is: a) The person who downloads the file goes to a web page, enters animal ID into a form, chooses .dbf file and uploads to a mysql database on the server (I still have to write php code to read the dbf and write sql insert statements from it). b) Everyone syncs from their local access database to the server. (This is natively possible from access but very clunky). Is there a tool (preferably open source), that can compare a access table to mysql table and sync the two (both ways)? Alternatively, does anyone have a more elegant solution? The ultimate goal is to allow everyone to have access to the most current data on their computers using their preferred database app.

• Looking for something to add some standard rules for my c++ project.

  - by rkb

  Hello all, My team is developing a C++ project on linux. We use vim as editor. I want to enforce some code standard rules in our team in such a way that if the code is not in accordance with it, some sort of warning or error will be thrown when it builds or compiles. Not necessarily it builds but at least I can run some plugin or tools on that code to make sure it meets the standard. So that before committing to svn everyone need to run the code through some sort of plugin or script and make sure it meets the requirement and then only he/she can commit. Not sure if we can add some rules to vim, if there are any let me know about it. For eg. In our code standards all the member variables and private functions should start with _ class A{ private: int _count; float _amount; void _increment_count(){ ++_count; } } So I want to throw some warning or error or some sort of messages for this class if the variables are declared as follows. class A{ private: int count; float amount; void increment_count(){ ++_count; } } Please note that warning and error are not from compiler becoz program is still valid. Its from the tool I want to use so that code goes to re-factoring but still works fine on the executable side. I am looking for some sort of plugin or pre parsers or scripts which will help me in achieving all this. Currently we use svn; just to anser the comment.

• List of running minimum values

  - by scarle88

  Given a sorted list of: new []{1, 2, -1, 3, -2, 1, 1, 2, -1, -3} I want to be able to iterate over the list and at each element return the smallest value iterated so far. So given the list above the resultant list would look like: 1 1 -1 -1 -2 -2 -2 -2 -2 -3 My rough draft code looks like: var items = new []{1, 2, -1, 3, -2, 1, 1, 2, -1, -3}; var min = items.First(); var drawdown = items.Select(i => { if(i < min) { min = i; return i; } else { return min; } }); foreach(var i in drawdown) { Console.WriteLine(i); } But this is not very elegant. Is there an easier to read (linq?) way of doing this? I looked into Aggregate but it seemed to be the wrong tool. Ultimately the list of items will be very long, in the many thousands. So good performance will be an issue to.

• Analyzing BSOD without a dump

  - by eeoo2555

  One of the drivers I'm developing has caused a BSOD. Unfortunately a dump file was not created since it was not configured / low resources. I was trying to reproduce this crash but no luck so far. Is there any way to get some info using WinDbg or any other tool? I have this information: A screenshot of the BSOD The .sys file. Its pdb The source code The machine it was crashed on I have everything except the dump itself. Your help will be much appreciated. As I said above, no dump (/minidump) exists. This is the actual problem. For this specific crash, I know I won't be able to get the stack. Just getting the specific line of code will be good enough. Because the BSOD contains the module's address, it seems like there should be a way to detect which line exactly is it. As I mentioned above, I do have the .sys file, the pdb and the source code. This is the specific code taken from MSDN: SYSTEM_SERVICE_EXCEPTION. How can I know from there what was the specific line? and/or the specific exception raised?

• 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.

• Edit Text in a Webpage with Internet Explorer 8

  - by Matthew Guay

  Internet Explorer is often decried as the worst browser for web developers, but IE8 actually offers a very nice set of developer tools.  Here we’ll look at a unique way to use them to edit the text on any webpage. How to edit text in a webpage IE8’s developer tools make it easy to make changes to a webpage and view them directly.  Simply browse to the webpage of your choice, and press the F12 key on your keyboard.  Alternately, you can click the Tools button, and select Developer tools from the list. This opens the developer tools.  To do our editing, we want to select the mouse button on the toolbar “Select Element by Click” tool. Now, click on any spot of the webpage in IE8 that you want to edit.  Here, let’s edit the footer of Google.com.  Notice it places a blue box around any element you hover over to make it easy to choose exactly what you want to edit. In the developer tools window, the element you selected before is now highlighted.  Click the plus button beside that entry if the text you want to edit is not visible.   Now, click the text you wish to change, and enter what you wish in the box.  For fun, we changed the copyright to say “©2010 Microsoft”. Go back to IE to see the changes on the page! You can also change a link on a page this way: Or you can even change the text on a button: Here’s our edited Google.com: This may be fun for playing a trick on someone or simply for a funny screenshot, but it can be very useful, too.  You could test how changes in fontsize would change how a website looks, or see how a button would look with a different label.  It can also be useful when taking screenshots.  For instance, if I want to show a friend how to do something in Gmail but don’t want to reveal my email address, I could edit the text on the top right before I took the screenshot.  Here I changed my Gmail address to [email protected]. Please note that the changes will disappear when you reload the page.  You can save your changes from the developer tools window, though, and reopen the page from your computer if you wish. We have found this trick very helpful at times, and it can be very fun too!  Enjoy it, and let us know how you used it to help you!

• Visual Studio App.config XML Transformation

  - by João Angelo

  Visual Studio 2010 introduced a much-anticipated feature, Web configuration transformations. This feature allows to configure a web application project to transform the web.config file during deployment based on the current build configuration (Debug, Release, etc). If you haven’t already tried it there is a nice step-by-step introduction post to XML transformations on the Visual Web Developer Team Blog and for a quick reference on the supported syntax you have this MSDN entry. Unfortunately there are some bad news, this new feature is specific to web application projects since it resides in the Web Publishing Pipeline (WPP) and therefore is not officially supported in other project types like such as a Windows applications. The keyword here is officially because Vishal Joshi has a nice blog post on how to extend it’s support to app.config transformations. However, the proposed workaround requires that the build action for the app.config file be changed to Content instead of the default None. Also from the comments to the said post it also seems that the workaround will not work for a ClickOnce deployment. Working around this I tried to remove the build action change requirement and at the same time add ClickOnce support. This effort resulted in a single MSBuild project file (AppConfig.Transformation.targets) available for download from GitHub. It integrates itself in the build process so in order to add app.config transformation support to an existing Windows Application Project you just need to import this targets file after all the other import directives that already exist in the *.csproj file. Before – Without App.config transformation support ... <Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" /> <Target Name="BeforeBuild"> </Target> <Target Name="AfterBuild"> </Target> </Project> After – With App.config transformation support ... <Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" /> <Import Project="C:\MyExtensions\AppConfig.Transformation.targets" /> <Target Name="BeforeBuild"> </Target> <Target Name="AfterBuild"> </Target> </Project> As a final disclaimer, the testing time was limited so any problem that you find let me know. The MSBuild project invokes the mage tool so the Framework SDK must be installed. Update: I finally had some spare time and was able to check the problem reported by Geoff Smith and believe the problem is solved. The Publish command inside Visual Studio triggers a build workflow different than through MSBuild command line and this was causing problems. I posted a new version in GitHub that should now support ClickOnce deployment with app.config tranformation from within Visual Studio and MSBuild command line. Also here is a link for the sample application used to test the new version using the Publish command with the install location set to be from a CD-ROM or DVD-ROM and selected that the application will not check for updates. Thanks to Geoff for spotting the problem.

• Developer’s Life – Every Developer is a Batman

  - by Pinal Dave

  Batman is one of the darkest superheroes in the fantasy canon.  He does not come to his powers through any sort of magical coincidence or radioactive insect, but through a lot of psychological scarring caused by witnessing the death of his parents.  Despite his dark back story, he possesses a lot of admirable abilities that I feel bear comparison to developers. Batman has the distinct advantage that his alter ego, Bruce Wayne is a millionaire (or billionaire in today’s reboots).  This means that he can spend his time working on his athletic abilities, building a secret lair, and investing his money in cool tools.  This might not be true for developers (well, most developers), but I still think there are many parallels. So how are developers like Batman? Well, read on my list of reasons. Develop Skills Batman works on his skills.  He didn’t get the strength to scale Gotham’s skyscrapers by inheriting his powers or suffering an industrial accident.  Developers also hone their skills daily.  They might not be doing pull-ups and scaling buldings, but I think their skills are just as impressive. Clear Goals Batman is driven to build a better Gotham.  He knows that the criminal who killed his parents was a small-time thief, not a super villain – so he has larger goals in mind than simply chasing one villain.  He wants his city as a whole to be better.  Developers are also driven to make things better.  It can be easy to get hung up on one problem, but in the end it is best to focus on the well-being of the system as a whole. Ultimate Teamplayers Batman is the hero Gotham needs – even when that means appearing to be the bad guys.  Developers probably know that feeling well.  Batman takes the fall for a crime he didn’t commit, and developers often have to deliver bad news about the limitations of their networks and servers.  It’s not always a job filled with glory and thanks, but someone has to do it. Always Ready Batman and the Boy Scouts have this in common – they are always prepared.  Let’s add developers to this list.  Batman has an amazing tool belt with gadgets and gizmos, and let’s not even get into all the functions of the Batmobile!  Developers’ skills might be the knowledge and skills they have developed, not tools they can carry in a utility belt, but that doesn’t make them any less impressive. 100% Dedication Bruce Wayne cultivates the personality of a playboy, never keeping the same girlfriend for long and spending his time partying.  Even though he hides it, his driving force is his deep concern and love for his friends and the city as a whole.  Developers also care a lot about their company and employees – even when it is driving them crazy.  You do your best work when you care about your job on a personal level. Quality Output Batman believes the city deserves to be saved.  The citizens might have a love-hate relationship with both Batman and Bruce Wayne, and employees might not always appreciate developers.  Batman and developers, though, keep working for the best of everyone. I hope you are all enjoying reading about developers-as-superheroes as much as I am enjoying writing about them.  Please tell me how else developers are like Superheroes in the comments – especially if you know any developers who are faster than a speeding bullet and can leap tall buildings in a single bound.
