• Google penalty recovery

  - by sajeev

  I have a site, which is a spiritual site and has nothing to do with commercial or business thing. It was in the first page with the keyword RADHANATH SWAMI. Then suddenly, in sep'13, the site went out from google search. When I checked my WebmasterTools, I saw that there were 40,000 backlinks from a site named http://freeguestbooks.net. But manual action section in WebmasterToolssaid "No Manual webspam actions found" and till date, it shows the same. Then I contacted the webmaster of freeguestbooks.net and requested him to remove the 40K odd backlinks and he very kindly removed it. The WebmasterTools now shows 21,777 backlinks from this site. But since 2 months, the decrease rate of these backlinks is very slow, almost zero. Again, I had contacted the webmaster of freeguestbooks.net and he confirmed that there are no backlinks pointing to his site. I am also told that my anchor text is over-optimised... Total backlinks to my site as per WebmasterTools is only 24,937 out of which 21,777 are the links from freeguestbooks.net as shown in WebmasterTools. Could an expert suggest a way out to get back into google.... Sajeev, India

• SQL to XML open data made simple

  - by drrwebber

  The perennial question for people is how to easily generate XML from SQL table content?  The latest CAM Editor release really tackles this head on by providing a powerful and simple toolset.  Firstly you can visually browse your SQL tables and then drag and drop from columns and tables into the XML structure editor.   This gives you a code-free method of describing the transformation you require.  So you do not need to know about the vagaries of XML and XSD schema syntax. Second you can map directly into existing industry domain XML exchange structures in the XML visual editor, again no need to wrestle with XSD schema, you have WYSIWYG visual control over what your output will look like. If you do not have a target XML structure and need to build one from scratch, then the CAM Editor makes this simple.  Switch the SQL viewer into designer mode, then take your existing SQL table and drag and drop it into the XML structure editor.  Automatically the XML wizard tool will take your SQL column names and definitions and create equivalent XML for you and insert the mappings. Simply save the structure template, and run the Open Data generator menu option, and your XML is built for you. Completely code-free template driven development. To see this in action, see our video demonstration links and then download the tools and samples and try it yourself.

• Information about rendering, batches, the graphical card, performance etc. + XNA?

  - by Aidiakapi

  I know the title is a bit vague but it's hard to describe what I'm really looking for, but here goes. When it comes to CPU rendering, performance is mostly easy to estimate and straightforward, but when it comes to the GPU due to my lack of technical background information, I'm clueless. I'm using XNA so it'd be nice if theory could be related to that. So what I actually wanna know is, what happens when and where (CPU/GPU) when you do specific draw actions? What is a batch? What influence do effects, projections etc have? Is data persisted on the graphics card or is it transferred over every step? When there's talk about bandwidth, are you talking about a graphics card internal bandwidth, or the pipeline from CPU to GPU? Note: I'm not actually looking for information on how the drawing process happens, that's the GPU's business, I'm interested on all the overhead that precedes that. I'd like to understand what's going on when I do action X, to adapt my architectures and practices to that. Any articles (possibly with code examples), information, links, tutorials that give more insight in how to write better games are very much appreciated. Thanks :)

• SEO, IIS 7 and web.config in subfolder issue

  - by tesicg

  We have ASP.NET application that has sub-folder with .aspx pages and separate web.config file in it. The .aspx pages in that sub-folder behave as separate site. In the web.config file at application level, I set the rule that removing trailing slashes: <rewrite> <rules> <rule name="RemoveTrailingSlashRule1" stopProcessing="true"> <match url="(.*)/$" /> <conditions> <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" /> <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" /> </conditions> <action type="Redirect" redirectType="Permanent" url="{R:1}" /> </rule> </rules> </rewrite> I expect this rule will propagate downward to sub-folder as well. To access the site in sub-folder we should type: http://concert.local/elki/ and get it without trailing slash as: http://concert.local/elki But, the trailing slash remains. The web.config file in sub-folder looks as following: <configuration> <system.webServer> <defaultDocument> <files> <add value="Sections.aspx" /> </files> </defaultDocument> </system.webServer> </configuration>

• iOS - UISlider - How to make a slider to auto-move [closed]

  - by drodri420

  its me again. Coming back with another noobish question: This time its , can you make a UISlider move by itself??? I've implemented this on the .m ///This right here makes a slider move 1point from 1 to 100, once it reaches 100 it goes backwards and so on... - (IBAction)moveSlider:(UISlider *)sender { int flag=0, counter=1; while(flag == 0) { counter = counter + (.25 * round); if(counter == 100) { flag = 1; } if(counter < 100 && counter > 1) { slider.value = counter; } } while(flag == 1) { counter = counter - (.25 * round); if(counter == 1) { flag = 0; } if(counter < 100 && counter > 1) { slider.value = counter; } } } And Implemented this on another action: -(void)startNewRound { round+=1; targetValue = 1 + (arc4random() % 100); self.slider.value = currentValue; [self moveSlider:slider]; } I think I lost it along the way and Im just typing pure nonsense but If anyone could point me in the right direction on to which is it that Im doing wrong??

• Non-dynamic CMS [closed]

  - by user20457

  Some of the web sites I visit every day (news, sports, etc..), although the content changes very often (several times per day), the URLs always have .html extension, what makes me thing that the content has been generated once, and then published as a static page, rather than generated in every call, or even cached in memory. For example, the fictitious site "mysports.com" have a "futbol.html" page, and then yesterday Messi gets injured and they have another thing to put in that page, then I presume they post the new item in their CMS system, and automatically a publishing action is triggered aftewards that recreates "futbol.html" in a CDN with the new item and probably discard the oldest one. Then the ETag changes and clients will get the new page if they try to access it. (the site is fictitious but this is what I believe happened yesterday in the sports site I read) This would fit in the CQRS approach, and I presume they have a huge performance. I know lots of CMS (WP, Drupal, BlogEngine.net, DNN, etc...), but I have never seen any able of doing this, or at least, I was not aware this feautre. How are called those distributed CMS? Which are the most well known? Cheers.

• Cannot create a neutral unit with a trigger

  - by Xitcod13

  I've been playing around with the starcraft UMS (Use map settings) for a while and usually i figure things out pretty quickly when im stuck. Alas not this time. I'm trying to place a neutral unit (player 12) using a trigger. It refuses to work. I'm using Scmdraft 2.0 as my editor (but i cant get it to work in other editors either) (all neutral units placed before the game starts are visible and all other triggers work fine. Also i created a text msg and it does displays it in-game so the trigger triggers ) For testing I created a trigger that looks like this: Player: neutral (i tried neutral players player 1 and all players as well) Condition: -always Action: -Create *1 Terran Medic* at '*location 022*' for *Neutral* (also tried neutral players) When I start the game nothing happens. Here is what I tried: I tried placing a start location for neutral player (player 12) I tried changing the owner under map properties of player 12 to neutral and computer from unused which was the default. Although it seems like it should be a common enough problem, I don't see it in any FAQ and I cant find anything about it when I Google it. Thanks in advance.

• How to prevent Network Manager from auto creating network connection profiles with "available to everyone" by default

  - by airtonix

  We have several laptops at work which use Ubuntu 11.10 64bit. I have our Wifi Access Point requiring WPA2-EAP Authentication (backed by a LDAP server). I have the staff using these laptops when doing presentations by using the Guest Account. So by default when you have a wifi card, network manager will display available Wireless Access Points. So the logical course of action for a Novice(tm) user is to single left click the easy to use option in the Network Manager drop down list... At this point the Staff Member (who is logged in with the guest account) expects to just be able to connect and enter any authentication details if required. But because they are using the Guest account, they won't ever have admin permissions (nor do I want them to), and so PolKit kicks in with a request for admin authorisation. I solved this part by modifying the PolKit permissions required to allow all users to create System Network Connections... However, because these Staff members are logging onto the Wifi Access Point with Ldap Credentials and because the Network Manager is now saving those credentials as a System Connection, their password is available for the next guest user session (because system connection profiles are stored in /etc/NetworkManager/system-connections.d/* ). It creates system connections by default because "Available to all users" is ticked by default when you quickly connect to a new wifi access point. I want Network Manager to not tick this by default. This way I can revert the changes I made to Polkit and users network connection profiles will be purged when they log out.

• Resurrecting a 5,000 line test plan that is a decade old

  - by ale

  I am currently building a test plan for the system I am working on. The plan is 5,000 lines long and about 10 years old. The structure is like this: 1. test title precondition: some W needs to be set up, X needs to be completed action: do some Y postcondition: message saying Z is displayed 2. ... What is this type of testing called ? Is it useful ? It isn't automated.. the tests would have to be handed to some unlucky person to run through and then the results would have to be given to development. It doesn't seem efficient. Is it worth modernising this method of testing (removing tests for removed features, updating tests where different postconditions happen, ...) or would a whole different approach be more appropriate ? We plan to start unit tests but the software requires so much work to actually get 'units' to test - there are no units at present ! Thank you.

• Choosing the correct network protocol for my type of game (its Wc3 Warlock style)

  - by Moritz

  I need to code a little game for a school project. The type of the game is like the Warcraft 3 map "Warlock", if anyone doesnt know it, here is a short description: up to ten players spawn into an arena filled with lava, the goal of each player is to push the other players into the lava with spells (basically variations of missiles, aoe nukes, moba spells etc) http://www.youtube.com/watch?v=c3PoO-gcJik&feature=related we need to provide multiplayer-support over the internet, for that reason I am looking for the best network protocol for this type of game (udp, tcp, lock step, client-server...) what the requirements are: - same/stable simulation on all clients - up to ten players - up to ~100 missiles on the field - very low latency since its reaction based (i dont know the method wc3 used, but it was playable with the old servers) what would be nice (if even possible, since the traffic might be too big): - support for soft bodies over the network (with bullet physics), but this is no real requirement I read several articles about the lock step method used for RTS games, this seems to be great, but does it fit for real-time action games too (ping-related)? If anyone has run into the same problems/questions like me, I would be very happy about any help

• How to implement isValid correctly?

  - by Songo

  I'm trying to provide a mechanism for validating my object like this: class SomeObject { private $_inputString; private $_errors=array(); public function __construct($inputString) { $this->_inputString = $inputString; } public function getErrors() { return $this->_errors; } public function isValid() { $isValid = preg_match("/Some regular expression here/", $this->_inputString); if($isValid==0){ $this->_errors[]= 'Error was found in the input'; } return $isValid==1; } } Then when I'm testing my code I'm doing it like this: $obj = new SomeObject('an INVALID input string'); $isValid = $obj->isValid(); $errors=$obj->getErrors(); $this->assertFalse($isValid); $this->assertNotEmpty($errors); Now the test passes correctly, but I noticed a design problem here. What if the user called $obj->getErrors() before calling $obj->isValid()? The test will fail because the user has to validate the object first before checking the error resulting from validation. I think this way the user depends on a sequence of action to work properly which I think is a bad thing because it exposes the internal behaviour of the class. How do I solve this problem? Should I tell the user explicitly to validate first? Where do I mention that? Should I change the way I validate? Is there a better solution for this? UPDATE: I'm still developing the class so changes are easy and renaming functions and refactoring them is possible.

• Setting up a LAMP VM server for Development and Testing?

  - by TdotThomas

  Info: I would like to set up a VM server on my local computer which will serve pages in the exact same way as my current hosting (but only to me on my local computer). I currently pay a big web hosting company to host my website & web store and they are doing a great job, but I would like to be able to work on my Web site and its corresponding MySQL DB, HTML, and PHP code without being at risk of messing something completely up on the live servers. My current plan of action: Set up a VM webserver with Debian, MySQL, PHP, Apache. Copy web store (PHP/HTML) code to VM server. Copy my current MySQL databases from my hosting provider and install on VM server. Modify and test new features on VM server. Upload MySQL DB and HTML/PHP code back to web host's server where it should work as before but with new modifications. Questions: Now I'm pretty sure I have steps one and two down correctly but I can't for the life of me figure out how to proceed next, so here are my questions. I have my /etc/host file set up so www.MySite.test redirects to the IP address of the local VM webserver. Once I import my PHP/HTML files and MySQL file whats the best way to navigate around the fact that all of my files and DBs will reference www.MySite.com. I can export my MySQL dbs but do I also have to export my MySQL users and passwords to access those db or are those coded into my html/php code?

• Can't connect nonlocally after 12.10 upgrade

  - by user101815

  I've just upgraded one of my systems from 12.04 to 12.10. Now I can't connect on that system beyond my local network. Connections within the local network seem to work fine, and I can make nonlocal connections from other machines (like the one I'm asking this question from). I suspect that some routing information has been messed up, but I don't know where to look for it. It's not a nameserver problem -- pinging outside sites by their IP addresses doesn't work either. I have another laptop next to this one, also running Kubuntu 12.10. On the one that can't connect, arp produces no output. On the other one, it produces 192.168.0.1 ether 00:23:69:fa:ce:ae C wlan0 On the working machine, the output of netstat starts with some tcp entries. On the nonworking one, those entries are absent. I asked this question on the Ubuntu forum but haven't gotten any answers there. One further complication: since the troublesome machine has no outside connection, it's extremely difficult to download anything to it. For what it's worth, "ping 8.8.8.8" produces "connect: Network is unreachable". Update: after a lot of fiddling, I have my external world back. I don't know what the key action was, but the first indication of progress was that "ping 8.8.8.8" worked. At that point I still didn't have a working nameserver, so external URLs didn't work. But I did this (based on an online post, of course): sudo dpkg-reconfigure resolvconf and answered Yes to all prompts. That did the trick!! Apparently my problem was unique, or close to it, since I couldn't find any online references to it: local net working, remote net not working, including explicit IP addresses. So I suppose that if no one else has this problem, no one cares about the solution!!

• How to choose between Tell don't Ask and Command Query Separation?

  - by Dakotah North

  The principle Tell Don't Ask says: you should endeavor to tell objects what you want them to do; do not ask them questions about their state, make a decision, and then tell them what to do. The problem is that, as the caller, you should not be making decisions based on the state of the called object that result in you then changing the state of the object. The logic you are implementing is probably the called object’s responsibility, not yours. For you to make decisions outside the object violates its encapsulation. A simple example of "Tell, don't Ask" is Widget w = ...; if (w.getParent() != null) { Panel parent = w.getParent(); parent.remove(w); } and the tell version is ... Widget w = ...; w.removeFromParent(); But what if I need to know the result from the removeFromParent method? My first reaction was just to change the removeFromParent to return a boolean denoting if the parent was removed or not. But then I came across Command Query Separation Pattern which says NOT to do this. It states that every method should either be a command that performs an action, or a query that returns data to the caller, but not both. In other words, asking a question should not change the answer. More formally, methods should return a value only if they are referentially transparent and hence possess no side effects. Are these two really at odds with each other and how do I choose between the two? Do I go with the Pragmatic Programmer or Bertrand Meyer on this?

• JQueryMobile - Problems with dialog boxes [closed]

  - by Richard van Hees

  I'm programming in JQueryMobile, but I can't seem to get some things as I want. First it's good to tell I am mostly programming in a multi-page template. I have a login function in the web based app. The idea is that the user sees he's not logged in and the user can click on the button to log in. A dialog box pops up, in which the user can enter his credentials. This dialog box is in front of the previous page, in my case just index.php. The page for profile is at profile.php#profile. In this case the url for the dialog box is index.php#profile&ui-state=dialog. Don't ask me why, that's how JQueryMobile works, I guess. Anyway, after the user clicks on 'Login' in the pop-up, I want a new dialog to pop-up in which it says you are logged in and I want the content of the page behind it (index.php#profile) to refresh. Of course I want this all to move very smooth and no refreshing of the whole page, to prevent loading time and thus a blank screen for a second. In short: User not logged in Clicks on login Dialog pops up with form Clicks login New dialog pops up with 'success' (or whatever) in the same style as the previous dialog Clicks ok Page behind the dialogues has been refreshed without user noticing Also another thing that doesn't really work out for me: I can't seem to get a dialog to pop up, triggered by an action in another dialog. It just appears as a normal page.

• How to pass dynamic information between a form and a service? [closed]

  - by qminator

  I have a design problem and hopefully the braintrust which is stack exchange can help. I have a generic form, which loads a dataset and displays it. It never has direct knowledge of what it contains but can pass it to a service for manipulation (via an Onclick event for example). However, the form might need to alter its behaviour based on the manipulation by the service. Example: The service realises this dataset requires sending of an email by the user and needs to send an instruction to the form to open up a mail form. My idea is thus: I'm thinking about passing back some type of key/name dictionary, filled with commands which the service requires. They could then be interpeted by the form without it need to reference something specific. Example: IF the service decides that the dataset needs to refresh it would send back a key/name pair, I might even be able to chain commands. Refreshing the dataset and sending a mail. Refresh / "Foo" Mail / "[email protected]" The form would reference an action explicitly (Refresh or Mail) but not the instructions themselves. Is this a valid idea or am I wasting time?

• New functionality in TFS Build Manager &ndash; Managing Triggers and Build Resources

  - by Jakob Ehn

  Yesterday we pushed out a new release (August 2012) of the Community TFS Build Extension, including a new version of the Community TFS Build Manager (1.0.4.6) The two big new features in the Build Manager in this release are: Set Triggers It is now possible to select one or more build definitions and update the triggers for them in one simple operation: You’ll note that we have started collapsing the context menu a bit, the list of commands are getting long! When selecting the Trigger command, you’ll see a dialog where the options should be self-explanatory: The only thing missing here is the Scheduled trigger option, you’ll have to do that using Team Explorer for now.   Manage Build Resources The other feature is that it is now possible to view the build controllers and agents in your current collection and also perform some actions against them. The new functionality is available by select the Build Resources item in the drop down menu: Selecting this, you’ll see a (sort of) hierarchical view of the build controllers and their agents: In this view you can quickly see all the resources and their status. You can also view the build directory of each build agent and the tags that are associated with them. On the action menu, you can enable and disable both agents and controllers (several at a time), and you can also select to remove them. By selecting Manage, you’ll be presented with the standard Manage Controller dialog from Visual Studio where you can set the rest of the properties. Hopefully we’ll be able to implement most of the existing functionality so that we can remove that menu option Our plan is to add more functionality to this view, such as adding new agents/controllers, restarting build service hosts, maybe view diagnostic information such as disk space and error logs.   Hope you’ll find the new functionality useful. Remember to log any bugs and feature requests on the CodePlex site. Happy building!

• Allow (and correct the URL) when there is a special character such as %26 using IIS and the rewrite module

  - by plumtreematt

  I'm struggling with a legacy app that uses special characters like %26 in the URL. The characters don't affect the app but can't be changed, so I'm trying to get IIS to deal with them. I've tried to ignore them using multiple methods, but nothing seems to work. So now I installed the IIS rewrite module and added a rewrite rule to web.config to replace the characters %26 with _, for example: <rewrite> <rules> <rule name="ampersand" patternSyntax="Wildcard" stopProcessing="true"> <match url="*%26*" /> <action type="Redirect" url="{R:1}_{R:2}" /> </rule> </rules> </rewrite> The problem is that IIS responds with "Bad Request" before the rewrite rule ever gets called. So my question is this: how can I change the order of precedence so that the mod rewrite filter will be called before IIS puts the ban hammer down on that URL?

• Lwjgl camera causing movement to be mirrored

  - by pangaea

  I'm having a problem in that everything is rendered and the movement is fine. However, everything seems to be mirrored. In the sense that the TriangleMob should move towards me, but it doesn't instead it mirrors my action. I move forward the TriangleMob moves backwards. I move left, it moves right. I move backwards, it moves forward. The code works if I do this glPushMatrix(); glTranslatef(-position.x, -position.y, -position.z); glCallList(objectDisplayList); glPopMatrix(); However, I'm scared this will cause a problem later on. I suppose the code works. However, shouldn't the call be glPushMatrix(); glTranslatef(position.x, position.y, position.z); glCallList(objectDisplayList); glPopMatrix(); I think the problem could be caused by how I'm doing the camera, which is this glLoadIdentity(); glRotatef(player.getRotation().x, 1.0f, 0.0f, 0.0f); glRotatef(player.getRotation().y, 0.0f, 1.0f, 0.0f); glRotatef(player.getRotation().z, 0.0f, 0.0f, 1.0f); glTranslatef(player.getPosition().x, player.getPosition().y, player.getPosition().z);

• Facebook contest policy no-no?

  - by Fred

  I would like to post a link on a Facebook page where it will exit Facebook entirely and go to a client's website, where people will be on a page (client's) where they can enter their e-mail address to be entered in a temporary database file with rules and disclosures etc., for a draw once the number of entries reaches 100 for instance. Once the number of entries reaches 100, a random winner is picked and notified via E-mail. The functionality is as follows: A link is place on a Facebook page leading to an external page The page is a form to merely enter their email address for a contest The email is placed in a temporary file An automatic E-mail is sent to the address used for confirmation using SHAH-256 hash The person receives the Email saying something to the affect "Please confirm your Email address etc. - If you did not authorize this, simply ignore this message and no further action will be taken". If the person clicks on the confirmation link, the Email is then stored in the database and the person is again notified saying "Thank you for signing up etc." Once others do the same process and the database reaches a certain number, the form is no longer accessible and automatically picks a random Email. Once picked, an Email is automatically sent to the winner stating the instructions, and notifying me also. Once that person clicks yet another confirmation link, the database is then automatically deleted. I have built this myself and have no intentions of breaking any rules, nor jeopardize the work/time/energy I have put into this project. Is this allowed?

• Mahout - Clustering - "naming" the cluster elements

  - by Mark Bramnik

  I'm doing some research and I'm playing with Apache Mahout 0.6 My purpose is to build a system which will name different categories of documents based on user input. The documents are not known in advance and I don't know also which categories do I have while collecting these documents. But I do know, that all the documents in the model should belong to one of the predefined categories. For example: Lets say I've collected a N documents, that belong to 3 different groups : Politics Madonna (pop-star) Science fiction I don't know what document belongs to what category, but I know that each one of my N documents belongs to one of those categories (e.g. there are no documents about, say basketball among these N docs) So, I came up with the following idea: Apply mahout clustering (for example k-mean with k=3 on these documents) This should divide the N documents to 3 groups. This should be kind of my model to learn with. I still don't know which document really belongs to which group, but at least the documents are clustered now by group Ask the user to find any document in the web that should be about 'Madonna' (I can't show to the user none of my N documents, its a restriction). Then I want to measure 'similarity' of this document and each one of 3 groups. I expect to see that the measurement for similarity between user_doc and documents in Madonna group in the model will be higher than the similarity between the user_doc and documents about politics. I've managed to produce the cluster of documents using 'Mahout in Action' book. But I don't understand how should I use Mahout to measure similarity between the 'ready' cluster group of document and one given document. I thought about rerunning the cluster with k=3 for N+1 documents with the same centroids (in terms of k-mean clustering) and see whether where the new document falls, but maybe there is any other way to do that? Is it possible to do with Mahout or my idea is conceptually wrong? (example in terms of Mahout API would be really good) Thanks a lot and sorry for a long question (couldn't describe it better) Any help is highly appreciated P.S. This is not a home-work project :)

• http request terminating early

  I noticed that on some of my sites, images were occasionally not getting downloaded fully. After a bit of investigation it appears that it is not restricted to images - .css, .js etc were also occasionally terminating early. The faults appear to be random. When I use the debug/proxy tool Fiddler2 reports that fewer bytes have been received than were requested. Firebug reports "Image corrupt or truncated". Obviously this is mainly a concern between me and my hosting company. However despite many emails they have not been able to get to the bottom of it. Transfer to another hosting company is obviously an option but is really a last resort. Has anyone seen this kind of thing before or can anyone suggest what might be causing it. Or any apache setting or something that I can ask them to check out. Will apache log this kind of error - they havent been able to provide me with any logs, but if I know exactly where things have been logged, maybe I can prompt them in to action.

• What makes you look like a bad developer (ie a hacker) [on hold]

  - by user134583

  This comes from a lot of people about me, so I have to look at myself. So I would wonder what make one a bad developer (ie a hacker). These are a few things about me I used IDE intensively, all features, you name it: auto-completion, refactoring, quick fixes, open type, view hierarchy, API documentation, etcc When I deal with writing code for a project in domain I am not used to (I can't have fluency in this, this is new), I only have a very rough high level ideas. I don't use the standard modeling diagrams for early detail planning. Unorthodox diagrams that I invented when I need to draw the design in details. I don't use UML or similar, I find them not enough. I divide the sorts of diagram I drew into 3 types. Very high level diagrams which probably can be understood by almost anybody. Data entity diagram used for modeling data objects only (like ER diagrams and tree for inheritances and composition). Action diagrams for agents/classes and their interactions on data objects they contain. Constantly changing the interface (public methods) between interacting agents/classes if the need arises. I am more refrained when the interface and the module have matured Write initial concept code in a quick hackie way just so that the module works in the general cases so that I can play around with it. The module will be re-factored intensively after playing around so I could see more corner cases that I couldn't or (wouldn't want) anticipate before writing code. Using JUnit for integration-like test by using TestSuite class and ordering Unit test classes in the suite Using debugger almost anytime there is a problem instead of reading the code Constantly search on the internet for how to do some thing with some library that I haven't used a lot. So judgment, am I a bad developer? a hacker? Put in other words, to make sure this is not considered off-topic: - Is this bad practice to make your code too agile during incubating/prototyping phase of software development - Is it bad practice to use JUnit for integration testing, (I know there are other framework for integration testing, but those frameworks are for a specific products, not general)
