• At what point would you drop some of your principles of software development for the sake of more money?

  - by MeshMan

  I'd like to throw this question out there to interestingly see where the medium is. I'm going to admit that in my last 12 months, I picked up TDD and a lot of the Agile values in software development. I was so overwhelmed with how much better my development of software became that I would never drop them out of principle. Until...I was offered a contracting role that doubled my take home pay for the year. The company I joined didn't follow any specific methodology, the team hadn't heard of anything like code smells, SOLID, etc., and I certainly wasn't going to get away with spending time doing TDD if the team had never even seen unit testing in practice. Am I a sell out? No, not completely... Code will always been written "cleanly" (as per Uncle Bob's teachings) and the principles of SOLID will always be applied to the code that I write as they are needed. Testing was dropped for me though, the company couldn't afford to have such a unknown handed to the team who quite frankly, even I did create test frameworks, they would never use/maintain the test framework correctly. Using that as an example, what point would you say a developer should never drop his craftsmanship principles for the sake of money/other benefits to them personally? I understand that this can be a very personal opinion on how concerned one is to their own needs, business needs, and the sake of craftsmanship etc. But one can consider that for example testing can be dropped if the company decided they would rather have a test team, than rather understand unit testing in programming, would that be something you could forgive yourself for like I did? So given that there is something you would drop, there usually should be an equal cost in the business that makes up for what you drop - hopefully, unless of course you are pretty much out for lining your own pockets and not community/social collaborating ;). Double your money, go back to RAD? Or walk on, and look for someone doing Agile, and never look back...

• Happy Tau Day! (Or: How Some Mathematicians Think We Should Retire Pi) [Video]

  - by Jason Fitzpatrick

  When you were in school you learned all about Pi and its relationship to circles and turn-based geometry. Some mathematicians are rallying for a new lesson, on about Tau. Michael Hartl is a mathematician on a mission, a mission to get people away from using Pi and to start using Tau. His manifesto opens: Welcome to The Tau Manifesto. This manifesto is dedicated to one of the most important numbers in mathematics, perhaps the most important: the circle constant relating the circumference of a circle to its linear dimension. For millennia, the circle has been considered the most perfect of shapes, and the circle constant captures the geometry of the circle in a single number. Of course, the traditional choice of circle constant is p—but, as mathematician Bob Palais notes in his delightful article “p Is Wrong!”,1 p is wrong. It’s time to set things right. Why is Pi wrong? Among the arguments is that Tau is the ration of a circumference to the radius of a circle and defining circles by their radius is more natural and that Pi is a 2-factor number but with Tau everything is based of a single unit–three quarters of a turn around a Tau-defined circle is simply three quarters of a Tau radian. Watch the video above to see the Tau sequence (which begins 6.2831853071…) turned into a musical composition. For more information about Tau hit up the link below to read the manifesto.

• Is there a better way to consume an ASP.NET Web API call in an MVC controller?

  - by davidisawesome

  In a new project I am creating for my work I am creating a fairly large ASP.NET Web API. The api will be in a separate visual studio solution that also contains all of my business logic and database interactions, Model classes as well. In the test application I am creating (which is asp.net mvc4), I want to be able to hit an api url I defined from the control and cast the return JSON to a Model class. The reason behind this is that I want to take advantage of strongly typing my views to a Model. This is all still in a proof of concept stage, so I have not done any performance testing on it, but I am curious if what I am doing is a good practice, or if I am crazy for even going down this route. Here is the code on the client controller: public class HomeController : Controller { protected string dashboardUrlBase = "http://localhost/webapi/api/StudentDashboard/"; public ActionResult Index() //This view is strongly typed against User { //testing against Joe Bob string adSAMName = "jBob"; WebClient client = new WebClient(); string url = dashboardUrlBase + "GetUserRecord?userName=" + adSAMName; //'User' is a Model class that I have defined. User result = JsonConvert.DeserializeObject<User>(client.DownloadString(url)); return View(result); } . . . } If I choose to go this route another thing to note is I am loading several partial views in this page (as I will also do in subsequent pages). The partial views are loaded via an $.ajax call that hits this controller and does basically the same thing as the code above: Instantiate a new WebClient Define the Url to hit Deserialize the result and cast it to a Model Class. So it is possible (and likely) I could be performing the same actions 4-5 times for a single page. Is there a better method to do this that will: Let me keep strongly typed views. Do my work on the server rather than on the client (this is just a preference since I can write C# faster than I can write javascript).

• Large enterprise application - clients wish to use duplicate e-mails addresses?

  - by Alex Key

  I'd like to know people's opinions, reactions to clients and technical work arounds (if applicable), to the issue of an enterprise application where a client wishes to use duplicate e-mail addresses? To clarify, when I say duplicate e-mail addresses I mean within the same client system, having multiple users that have the same e-mail address. So not just using generic e-mail addresses but using the e-mail address of another user. e.g. Bob Jenkins: [email protected] James Jeffery: [email protected] Context To give this some further context, in the e-learning sector it is common that although all staff in an organisation must complete e-learning - they may not have their own e-mail address so they choose to use their managers e-mail address. Albeit against good practice in public sites... it's a requirement we've over and over again where an organisation is split between office based staff and perhaps e.g. staff in a warehouse. Where problem lies Mr Steak, good point, the problem lies in password resets and perhaps in situations where semi-personal information could be sent (not confidential enough to worry about the insecurities of email). Perhaps reminders for specific system actions, which would be confusing for the unintended party to see (if perhaps misreading the e-mail's intended recipient) Possible solutions System knowing the difference between a "for the attention of" and direct to the person e-mails, including this in the body text. Using alternative communication such as SMS Simply not having e-mails sent to people who are not the intended recipient. Providing an e-mail service ourselfs (not really viable for a corporate IT dept) Thoughts?

• In the Aggregate: How Will We Maintain Legacy Systems? [closed]

  - by Jim G.

  NEW YORK - With a blast that made skyscrapers tremble, an 83-year-old steam pipe sent a powerful message that the miles of tubes, wires and iron beneath New York and other U.S. cities are getting older and could become dangerously unstable. July 2007 Story About a Burst Steam Pipe in Manhattan We've heard about software rot and technical debt. And we've heard from the likes of: "Uncle Bob" Martin - Who warned us about "the consequences of making a mess". Michael C. Feathers - Who gave us guidance for 'Working Effectively With Legacy Code'. So certainly the software engineering community is aware of these issues. But I feel like our aggregate society does not appreciate how these issues can plague working systems and applications. As Steve McConnell notes: ...Unlike financial debt, technical debt is much less visible, and so people have an easier time ignoring it. If this is true, and I believe that it is, then I fear that governments and businesses may defer regular maintenance and fortification against hackers until it is too late. [Much like NYC and the steam pipes.] My Question: Is there a way that we can avoid the software equivalent of NYC and the steam pipes?

• Moving while doing loop animation in RPGMaker

  - by AzDesign

  I made a custom class to display character portrait in RPGMaker XP Here is the class : class Poser attr_accessor :images def initialize @images = Sprite.new @images.bitmap = RPG::Cache.picture('Character.png') #100x300 @images.x = 540 #place it on the bottom right corner of the screen @images.y = 180 end end Create an event on the map to create an instance as global variable, tada! image popped out. Ok nice. But Im not satisfied, Now I want it to have bobbing-head animation-like (just like when we breathe, sometimes bob our head up and down) so I added another method : def move(x,y) @images.x += x @images.y += y end def animate(x,y,step,delay) forward = true 2.times { step.times { wait(delay) if forward move(x/step,y/step) else move(-x/step,-y/step) end } wait(delay*3) forward = false } end def wait(time) while time > 0 time -= 1 Graphics.update end end I called the method to run the animation and it works, so far so good, but the problem is, WHILE the portrait goes up and down, I cannot move my character until the animation is finished. So that's it, I'm stuck in the loop block, what I want is to watch the portrait moving up and down while I walk around village, talk to npc, etc. Anyone can solve my problem ? Or better solution ? Thanks in advance

• Overloading methods that do logically different things, does this break any major principles?

  - by siva.k

  This is something that's been bugging me for a bit now. In some cases you see code that is a series of overloads, but when you look at the actual implementation you realize they do logically different things. However writing them as overloads allows the caller to ignore this and get the same end result. But would it be more sound to name the methods more explicitly then to write them as overloads? public void LoadWords(string filePath) { var lines = File.ReadAllLines(filePath).ToList(); LoadWords(lines); } public void LoadWords(IEnumerable<string> words) { // loads words into a List<string> based on some filters } Would these methods better serve future developers to be named as LoadWordsFromFile() and LoadWordsFromEnumerable()? It seems unnecessary to me, but if that is better what programming principle would apply here? On the flip side it'd make it so you didn't need to read the signatures to see exactly how you can load the words, which as Uncle Bob says would be a double take. But in general is this type of overloading to be avoided then?

• Recursion in F#

  - by MarkPearl

  Things are slowly coming together – I was able to look at a bit of F# code and intuitively know what it was going to do (yay)… So today I saw a blog post by Bob Palmer on Fibonacci numbers in F# which inspired me to look at bit into recursion. First the C# example… class Program { public static void CountDown(int n) { switch (n) { case 0: Console.WriteLine("End of Count"); break; default: Console.WriteLine(n); CountDown(n-1); break; } } static void Main(string[] args) { CountDown(10); Console.ReadLine(); } }   In F#, the equivalent would look something like this… open System let rec CountDown n = match n with | 0 -> Console.WriteLine("End of Count"); | n -> Console.WriteLine(n); CountDown (n-1); CountDown 10 Console.ReadLine()   Pretty simple stuff. With F# you when making recursive calls you need to explicitly declare that the function is recursive with the “rec” keyword. Otherwise the code is pretty easy to read and self explanatory.

• tdd is about design not verification what does it concretely mean?

  - by sigo

  I've been wondering about this. What do we exactly mean by design and verification. Should I just apply tdd to make sure my code is SOLID and not check is correct external behaviour ? Should I use Bdd for the correct behaviour part ? Where I get confused also is regarding TDD code katas, to me they looked like more about verification than design... shouldn't they be called bdd katas instead of tdd katas? I reckon that for example uncle bob bowling kata leads in the end to a simple and nice internal design but I felt that most of the process was more around vérification than design. Design seemed to be a side effect of testing incrementally the external behaviour. I didnt feel so much that we were focusing most of our efforts on design but more on vérification. While normally we are told the contrary, that in TDD, verification is a side effect, design is the main purpose. So my question is what should i focus exactly on when i do tdd: SOLID, external Api usability, what else...? And how can I do that without being focused on verification ? What do you guys focus your energy on when you are practicing TDD ?

• How to cut the line between quality and time?

  - by m3th0dman

  On one hand, I have been taught by various software engineering books ([1] as example) that my job as a programmer is to make the best possible software: great design, flexibility, to be easily maintained etc. One the other hand although I realize that I actually write software for money and not for entertainment, although is very nice to write good code and plan ahead and refactor after writing and ... I wonder if it is always best for the business (after all we should be responsible). Is the business always benefiting from a best code? Maybe I'm over-engineering something, and it's not always useful? So how should I know when to stop in the process to achieving the best possible code? I am sure that experience is something that makes a difference here, but I believe this cannot be the only answer. [1] Uncle Bob's in Clean Code says at page 6 about the fact that: They [managers] may defend the schedule and requirements with passion; but that’s their job. It’s your job to defend the code with equal passion.

• MVC 4 Authentication

  - by Aligned

  First: After searching for awhile to figure out what’s new/different with MVC 4 and forms authentication, this is the best article I've found on the subject: http://weblogs.asp.net/jgalloway/archive/2012/08/29/simplemembership-membership-providers-universal-providers-and-the-new-asp-net-4-5-web-forms-and-asp-net-mvc-4-templates.aspx Some quotes from the article: “The ASP.NET Web Pages team designed SimpleMembership to (wait for it) simplify the task of dealing with membership” "WSAT is built to work with ASP.NET Membership, and is not compatible with Simple Membership. There are two main options there: Use the WebSecurity and OAuthWebSecurity API to manage the users and roles Create a web admin using the above APIs Since SimpleMembership runs on top of your database, you can update your users as you would any other data - via EF or even in direct database edits (in development, of course)" “If you want to use an existing ASP.NET Membership Provider in ASP.NET MVC 4, you can't use the new AccountController. You can do a few things:” “Universal Providers do not work with Simple Membership.” ~ this post (look for Bob.at.SBS’s answer) says Universal Providers is not needed for MVC 4 to work in Azure)   I've been trying to figure out the Forms Authentication in MVC4. It's different than the past approach (aspnet_regsql). If you do file new project -> MVC 4 -> internet application, you get a really nice template with the controller and model setup for you. However, the tables are different than using aspnet_regsql and the ASP.Net Configuration tool (WSAT) wasn’t connecting to the data I had (it was creating an App_Data/aspnet.mdf file, which I didn’t see right away). Points of Note The database tables are created in the SimpleMembershipInitializer class, when you first run your app using Entity Framework 5 migration functionality. The tables created are webpages_Membership, webpages_OAuthMembership, webpages_Roles, webpages_UsersInRoles, UserProfile. Web.config settings don’t seem to be needed.   Scott Hanselman on Universal Providers was also useful if not somewhat out dated. Universal Providers and SimpleMembership are not compatible. http://www.asp.net/web-pages/tutorials/security/16-adding-security-and-membership – walk-through

• SSH connection times out

  - by mark

  Given: vm - a WinXPsp3 virtual machine hosted by a Win7sp1 physical machine alice is the user on vm srv - a Win2008R2sp1 server bob is the user on srv quake - a linux server mark is the user on quake Both vm and srv have the same new installation of cygwin (1.7.9) and openssh. Firewall service is disabled on vm (and its host) and on srv All the machines can be pinged from all the machines. ssh mark@quake works OK from both vm and srv. ssh bob@srv works OK from both quake and vm. ssh alice@vm works on the vm itself only, but it fails on the other two machines: alice@vm ~ $ ssh alice@vm alice@vm's password: Last login: Tue Oct 25 23:42:09 2011 from vm.shunra.net [mark@Quake ~]$ ssh -vvv alice@vm OpenSSH_4.3p2, OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug2: ssh_connect: needpriv 0 debug1: Connecting to vm [172.30.2.60] port 22. debug1: connect to address 172.30.2.60 port 22: Connection timed out ssh: connect to host vm port 22: Connection timed out bob@Srv ~ $ ssh -vvv alice@vm OpenSSH_5.9p1, OpenSSL 0.9.8r 8 Feb 2011 debug1: Reading configuration data /etc/ssh_config debug2: ssh_connect: needpriv 0 debug1: Connecting to vm [172.30.2.60] port 22. debug1: connect to address 172.30.2.60 port 22: Connection timed out ssh: connect to host vm port 22: Connection timed out I used ssh-host-config both on vm and srv to configure the ssh to run as a windows service.

• PASS: Election Changes for 2011

  - by Bill Graziano

  Last year after the election, the PASS Board created an Election Review Committee.  This group was charged with reviewing our election procedures and making suggestions to improve the process.  You can read about the formation of the group and review some of the intermediate work on the site – especially in the forums. I was one of the members of the group along with Joe Webb (Chair), Lori Edwards, Brian Kelley, Wendy Pastrick, Andy Warren and Allen White.  This group worked from October to April on our election process.  Along the way we: Interviewed interested parties including former NomCom members, Board candidates and anyone else that came forward. Held a session at the Summit to allow interested parties to discuss the issues Had numerous conference calls and worked through the various topics I can’t thank these people enough for the work they did.  They invested a tremendous number of hours thinking, talking and writing about our elections.  I’m proud to say I was a member of this group and thoroughly enjoyed working with everyone (even if I did finally get tired of all the calls.) The ERC delivered their recommendations to the PASS Board prior to our May Board meeting.  We reviewed those and made a few modifications.  I took their recommendations and rewrote them as procedures while incorporating those changes.  Their original recommendations as well as our final document are posted at the ERC documents page.  Please take a second and read them BEFORE we start the elections.  If you have any questions please post them in the forums on the ERC site. (My final document includes a change log at the end that I decided to leave in.  If you want to know which areas to pay special attention to that’s a good start.) Many of those recommendations were already posted in the forums or in the blogs of individual ERC members.  Hopefully nothing in the ERC document is too surprising. In this post I’m going to walk through some of the key changes and talk about what I remember from both ERC and Board discussions.  I’ll pay a little extra attention to things the Board changed from the ERC.  I’d also encourage any of the Board or ERC members to blog their thoughts on this. The Nominating Committee will continue to exist.  Personally, I was curious to see what the non-Board ERC members would think about the NomCom.  There was broad agreement that a group to vet candidates had value to the organization. The NomCom will be composed of five members.  Two will be Board members and three will be from the membership at large.  The only requirement for the three community members is that you’ve volunteered in some way (and volunteering is defined very broadly).  We expect potential at-large NomCom members to participate in a forum on the PASS site to answer questions from the other PASS members. We’re going to hold an election to determine the three community members.  It will be closer to voting for Summit sessions than voting for Board members.  That means there won’t be multiple dedicated emails.  If you’re at all paying attention it will be easy to participate.  Personally I wanted it easy for those that cared to participate but not overwhelm those that didn’t care.  I think this strikes a good balance. There’s also a clause that in order to be considered a winner in this NomCom election, you must receive 10 votes.  This is something I suggested.  I have no idea how popular the NomCom election is going to be.  I just wanted a fallback that if no one participated and some random person got in with one or two votes.  Any open slots will be filled by the NomCom chair (usually the PASS Immediate Past President).  My assumption is that they would probably take the next highest vote getters unless they were throwing flames in the forums or clearly unqualified.  As a final check, the Board still approves the final NomCom. The NomCom is going to rank candidates instead of rating them.  This has interesting implications.  This was championed by another ERC member and I’m hoping they write something about it.  This will really force the NomCom to make decisions between candidates.  You can’t just rate everyone a 3 and be done with it.  It may also make candidates appear further apart than they actually are.  I’m looking forward talking with the NomCom after this election and getting their feedback on this. The PASS Board added an option to remove a candidate with a unanimous vote of the NomCom.  This was primarily put in place to handle people that lied on their application or had a criminal background or some other unusual situation and we figured it out. We list an explicit goal of three candidate per open slot. We also wanted an easy way to find the NomCom candidate rankings from the ballot.  Hopefully this will satisfy those that want a broad candidate pool and those that want the NomCom to identify the most qualified candidates. The primary spokesperson for the NomCom is the committee chair.  After the issues around the election last year we didn’t have a good communication plan in place.  We should have and that was a failure on the part of the Board.  If there is criticism of the election this year I hope that falls squarely on the Board.  The community members of the NomCom shouldn’t be fielding complaints over the election process.  That said, the NomCom is ranking candidates and we are forcing them to rank some lower than others.  I’m sure you’ll each find someone that you think should have been ranked differently.  I also want to highlight one other change to the process that we started last year and isn’t included in these documents.  I think the candidate forums on the PASS site were tremendously helpful last year in helping people to find out more about candidates.  That gives our members a way to ask hard questions of the candidates and publicly see their answers. This year we have two important groups to fill.  The first is the NomCom.  We need three people from our membership to step up and fill this role.  It won’t be easy.  You will have to make subjective rankings of your fellow community members.  Your actions will be important in deciding who the future leaders of PASS will be.  There’s a 50/50 chance that one of the people you interview will be the President of PASS someday.  This is not a responsibility to be taken lightly. The second is the slate of candidates.  If you’ve ever thought about running for the Board this is the year.  We’ve never had nine candidates on the ballot before.  Your chance of making it through the NomCom are higher than in any previous year.  Unfortunately the more of you that run, the more of you that will lose in the election.  And hopefully that competition will mean more community involvement and better Board members for PASS. Is this the end of changes to the election process?  It isn’t.  Every year that I’ve been on the Board the election process has changed.  Some years there have been small changes and some years there have been large changes.  After this election we’ll look at how the process worked and decide what steps to take – just like we do every year.

• Need personal advice on how to get out of a company..

  - by SOfan

  Hi, I am an SO user since past 6 months and this is the first time I am turning to SO for personal help. I have asked technical questions before with my real ID. I am stuck inside a service based IT company for the past one year and haven't been able to decide if to leave it, when to leave it and how to leave it. I had taken 2 weeks LWP on medical reason roughly at end of 1 year and then soon after reporting, I applied for 2 months more LWP (on medical/personal ground) with the intention of working on my health,take up a hobby class to ward off depression,pessimism, to have some fun in life, and to look for a job which I really would be excited about - that interests me and which matches with my strength. My leave starts from this Monday. So in any case, I had hard set in mind that I will leave the company after I join them back hopefully with some job offer already in hand (after figuring out what I want do). Neither I can stand the past project,past colleagues,company, HR, pathetically low salary. But if I really listen to my heart, I don't want to have to go back to that office after my sabbatical and again have to see those people. I will have to resign it after my sabbatical ends. Then HR people perhaps wont like it, may even accuse me on face or behind back that primary purpose of my leave must have been to hunt for a better job and I lied about medical and person reasons. Also, if they get nasty and force me to serve 2 months notice period. There is no way I see myself after sabbatical resuming in old project or starting new work. It will be a pain. Since they have already approved 2 months leave and stuff, ideally if they want, they should be just able to relieve me right on the next day after I join back. But, I don't know if they want to get nasty, will they mention about my 2 months sabbatical leave in my experience letter or more scary, the term medical/personal reason. I have hard earned my experience here, have worked against my will, mostly it has been painful and slogged like anything, because I realize the importance of work experience in IT industry. I don't have greed to have those 2 months included extra in my experience letter, but I don't want to mess up with my experience letter in a way which makes my next employer ask question, get suspicious, or be wary if I have any medical reason going on. Being an emotional,moody person or somebody who can't be in an environment, once my mind and heart starts hating it. I think it perhaps is best, if I resign on Monday itself telling them (in polite manner) something that look I took sabbatical for some reason but I don't want to resume working in the company after my sabbatical ends. So please accept my resignation. Now tell me what you want to do about my leave request, my notice period and when you are willing to relieve me. What should I write and how? Some background: I am working in an IT company in India.I am overqualified in the company. It is grossly underpaying me. My education qualifications far exceed anyone's in the whole company being a CS undergrad as well as a CS grad. I joined this company after finishing the grad. I had self-doubts about my skills and interest as a programmer. I like doing research oriented work, though didn't have any particular success during grad. My life here has been very hectic. The project containing many many sub-projects has kept me on my toes and I have never really liked the work. I have been playing against my strength. Also the company strict internet usage policy (you can't read gmails, can't browse any non-work related sites not even news). When working for a client, from the machine we can't even check company related emails.For this one has to go to kiosk like 5 machines in a small room etc. Most of the times those machines are not available, so it was not unusual to keep making rounds to these kiosk machines to check company emails, browse company related emails etc.So it was not so easy to keep in touch with company related basic affairs for a not particular careful person. Things like this which are new to me, make me feel restricted. I am an undecisive person with a sense of failure, self-doubt, not meeting up unrealistic expectation. Somewhere at back of mind, I envy my classmates who make a smooth transition from company to company without causing any gap in their resume. I on other hand have gaps in resume. I get tired after working in a place for sometime. problem with colleagues in general. I am not particular great with people, have few friends, not known for a fun nature, rather serious, scholar. I am not a typical conventional female. I think females are usually more disciplined. But I am not so. I reach office late (though after informing manager). I don't want to blame them entirely, because from my past, it is not unusual for me to get undecisive on things. Also I had doubts about my ability as researched and to succeed there. of building a relationship in a group, to have something to talk about, newspaper. I get cut-off from people. peer pressure. I make blunders in coding, lose patience. Consciously or unconsciously I feel contempt for people here, work here, environment here. I have doubts that either I go to a place which does innovation, does research oriented work, product biggies, have great motivated people, have competent people passionate about products they are building. But then I also doubt my ability to survive there. I have identified that an idea job for me would be 4 days a week, a high salary job. When among people in company/team, I can't think much. I need some time at home to read good authentic books written in good style on what work I am doing.So that I am comfortable with my understanding of work. I get into pressure easily under deadline and need 5th day to cool myself off. I took for 2 weeks leave, because each day was hell for me. May be the depression phase of bipolar is on and also partially it could be that being a work centered person, who derives happiness,self-esteem from work, haven't been enjoying work and have been working for the sole person of proving stability, and ability to stick, against all odds, and facing what challenges I see, bonding with people, identifying opportunities to learn in given task etc.have been averaging one day LWP in 1 week or 10 days. or may be because of my nature,ADD,not being able to switch context,out of touch with news, don't have a circle of friends with who I enjoy. less knowledge in general to talk about, just some technical stuff.anyway, so due to emotional reason, some practical reason etc, I wanted to be very sure before leaving. So my leave starts from Monday and I should feel happy about it. I have taken the leave to for a few purposes - to take care of my health by regular yoga/exercise (with project on, I just can't do anything regular), reassess myself to see what I want to try next which work I might like, look for next job, take up a hobby which I like say singing. I am not clear on my career,job aspiration. I have tried my hands on research. During this year appraisal yesterday, I even had some conflict with my last manager. In meeting with me one on one, he would say all nice things about me, but in feedback to new manager, he hasn't given any excellent feedback. It is all only good. I am angry at this old Manager. Also new manager also scolded me as I didn't agree to his appraisal and waited to hear myself from old Manager. He kind of scolded me for wasting his time. Am I being unethical somewhere? I am always very conscious of if I am cheating anywhere. What advice I am seeking? How to resign and what to write in resignation letter

• I'm a contract developer and I think I'm about to get screwed [closed]

  - by kagaku

  I do contract development on the side. You could say that I'm a contract developer? Considering I've only ever had one client I'd say that's not exactly the truth - more like I took a side job and needed some extra cash. It started out as a "rebuild our website and we'll pay you $10k" type project. Once that was complete (a bit over schedule, but certainly not over budget), the company hired me on as a "long term support" contractor. The contract is to go from March of this year, expiring on December 31st of this year - 10 months. Over which a payment is to be paid on the 30th of each month for a set amount. I've been fulfilling my end of the contract on all points - doing server maintenence, application and database changes, doing huge rush changes and pretty much just going above and beyond. Currently I'm in the middle of development of an iPhone mobile application (PhoneGap based) which is nearing completion (probably 3-4 weeks from submission). It has not been all peaches and flowers though. Each and every month when my paycheck comes due, there always seems to be an issue of sorts. These issues did not occur during the initial project, only during the support contract. The actual contract states that my check should be mailed out on the 30th of the month. I have received my check on time approximately once (on time being about 2-3 days within the 30th). I've received my paycheck as late as the 15th of the next month - over two weeks late. I've put up with it because I need the paycheck. There have been promises and promises of "we'll send it out on time next time! I promise" - only to receive it just as late the next month. When I ask about payment they give me a vibe like "why are you only worried about money?" - unfortunately I don't have the luxury of not worrying about money. The last straw was with my August payment, which should have been mailed on August 30th. I received it on September 12th. The reason for the delay? "USPS is delaying it man! we sent it out on the 1st!" is the reason I got. When I finally got the check in the mail, the postage on the envelope was marked September 10th - the date it was run through the postage machine. I've been outright lied to, at this point. I carry on working, because again - I need a paycheck. I orchestrated the move of our application to a new server, developed a bunch of new changes and continued work on the iPhone app. All told I probably went over my hourly allotment (I'm paid for 40 hours a month, I probably put in at least 50). On Saturday, the 1st, I gave the main contact at the company (a company of 3, by the way - this is not some big corporation) a ring and filled him in on the status of my work for the past two weeks. Unusually I hadn't heard from him since the middle of September. His response was "oh... well, that is nice and uh.. good job. well, we've been talking within the company about things and we've certainly got some decisions ahead of us..." - not verbatim but you get the idea (I hope?). I got out of this conversation that the site is not doing very well (which it's not) and they're considering pulling the plug. Crap, this contract is going to end early - there goes Christmas! Fine, that's alright, no problem. I'll get paid for the last months work and call it a day. Unfortunately I still haven't gotten last months check, and I'm getting dicked around now. "Oh.. we had problems transferring funds, we'll try and mail it out tomorrow" and "I left a VM with the finance guy, but I can't get ahold of him". So I'm getting the feeling I'm not getting paid for all the work I put in for September. This is obviously breach of contract, and I am pissed. Thinking irrationally, I considered changing all their passwords and holding their stuff hostage. Before I think it through (by the way, I am NOT going to do this, realized it would probably get me in trouble), I go and try some passwords for our various accounts. Google Apps? Oh, I'm no longer administrator here. Godaddy? Whoops, invalid password. Disqus? Nope, invalid password here too. Google Adsense / Analytics? Invalid password. Dedicated server account manager? Invalid password. Now, I have the servers root password - I just built the box last week and haven't had a chance to send the guy the root password. Wasn't in a rush, I manage the server and they never touch it. Now all of a sudden all the passwords except this one are changed; the writing is on the wall - I am out. Here's the conundrum. I have the root password, they do not. If I give them this password all the leverage I have is gone, out the door and out of my hands. During this argument of why am I not getting paid the guy sends me an email saying "oh by the way, what's the root username and password to the server?". Considering he knows absolutely nothing, I gave him an "admin" account which really has almost no rights. I still have exclusive access to the server, I just don't know where to go. I can hold their data hostage, but I'm almost positive this is the wrong thing to do. I'd consider it blackmail, regardless of whether or not I have gotten paid yet. I can "break" something on the server and give them the whole "well, if you were paying me I could fix it!" spiel. This works from a "well he's not holding their stuff hostage" point of view, but what stops them from hiring some one else to just fix the issue at hand? For all I know the guys nephew is a "l33t hax0r" and can figure it out for free. I can give in, document as much as I can and take him to small claims court. This is breach of contract, I'm not getting paid. I have a case, right? ???? Does anyone have any experience in this? What can I do? What are my options? I'm broke, I can't afford a lawyer and I can barely afford not getting this paycheck. My wife doesn't work (I work two jobs so she doesn't have to work - we have a 1 year old) and is already looking at getting a part time job to cover the bills. Long term we'll be fine, but this has pissed me off beyond belief! Help me out, I'm about to get screwed.

• php variable scope in oop

  - by mr o

  Hi, I wonder if anyone can help out here, I'm trying to understand how use an objects properties across multiple non class pages,but I can't seem to be able to get my head around everything i have tried so far. For example a class called person; class person { static $name; } but i have a number of different regular pages that want to utilize $name across the board. I have trying things like this; pageone.php include "person.php"; $names = new Person(); echo person::$name; names::$name='bob'; pagetwo.php include "person.php"; echo person::$name; I can work with classes to the extent I'm OK as long as I am creating new instances every page, but how can make the properties of one object available to all, like a shared variable ? Thanks

• Variable number of arguments in an Axis2 POJO

  - by Mike

  I have a web service that I built with Axis2/Java. The web service will take in a list of objects and will process them. I'll use the following operation as an example. public class AddToDatabaseService{ public void addToDatabase(String name1, String name2, String name3, ....) { //add names to database } } I want the caller of my web service to use a URI like: http://localhost:8080/axis2/services/addToDatabase?name1=Joe&name2=Bob&name3=Kelly&name4=... I'm aware this is not compilable code and the idea is still there. Is this even possible with SOAP-based web services? I know this is possible to do with RESTful services because you can just take the HttpServletRequest request object and do Enumeration enumeration = request.getParameterNames() and iterate through them. I'm looking for the equivalent of that in web services POJO's with Axis2. A link or an sample program would be great! Thanks.

• Sending Client Certificate in HttpWebRequest

  - by Aaron Fischer

  I am trying to pass a client certificate to a server using the code below however I still revive the HTTP Error 403.7 - Forbidden: SSL client certificate is required. What are the possible reasons the HttpWebRequest would not send the client certificate? var clientCertificate = new X509Certificate2( @"C:\Development\TestClient.pfx", "bob" ); HttpWebRequest tRequest = ( HttpWebRequest )WebRequest.Create( "https://ofxtest.com/ofxr.dll" ); tRequest.ClientCertificates.Add( clientCertificate ); tRequest.PreAuthenticate = true; tRequest.KeepAlive = true; tRequest.Credentials = CredentialCache.DefaultCredentials; tRequest.Method = "POST"; var encoder = new ASCIIEncoding(); var requestData = encoder.GetBytes( "<OFX></OFX>" ); tRequest.GetRequestStream().Write( requestData, 0, requestData.Length ); tRequest.GetRequestStream().Close(); ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback( CertPolicy.ValidateServerCertificate ); WriteResponse( tRequest.GetResponse() );

• idioms for returning multiple values in shell scripting

  - by Wang

  Are there any idioms for returning multiple values from a bash function within a script? http://tldp.org/LDP/abs/html/assortedtips.html describes how to echo multiple values and process the results (e.g., example 35-17), but that gets tricky if some of the returned values are strings with spaces in. A more structured way to return would be to assign to global variables, like foo () { FOO_RV1="bob" FOO_RV2="bill" } foo echo "foo returned ${FOO_RV1} and ${FOO_RV2}" I realize that if I need re-entrancy in a shell script I'm probably doing it wrong, but I still feel very uncomfortable throwing global variables around just to hold return values. Is there a better way? I would prefer portability, but it's probably not a real limitation if I have to specify #!/bin/bash.

• Resolving MSB3247 - Found conflicts between different versions of the same dependent assembly

  - by David Gardiner

  A .NET 3.5 solution ended up with this warning when compiling with msbuild. Sometimes NDepend might help out but in this case it didn't give any further details. Like Bob I ended up having to resort to opening each assembly in ILDASM until I found the one that was referencing an older version of the dependant assembly. I did try using MSBUILD from VS 2010 Beta 2 (as the Connect article indicated this was fixed in the next version of the CLR) but that didn't provide any more detail either (maybe fixed post Beta 2) Is there a better (more automated) approach?

• Delphi 2010 Datasnap - Design Query

  - by Matt

  I am investigating moving a thick client SQL based Delphi application to Multi Tier thin clients, and have been looking at using Datasnap in Delphi 2010. I have worked through the White Paper written by Bob Swart and extended this further. My main question really is that I want to make the server side efficient in terms of connections and SQL Queries due to multiple queries being run and remaining open at the same time to interrogate data, can anyone point me in a direction for guidance on how to design a real world Datasnap Server application, as the demo's don't go into enough detail. Thanks Matt
