• What should I do when my team leader is unfair for no reason? [closed]

  - by crucified soul

  I'm a new software developer and this is my first job. It's a startup and the CEO and the working environment is just great. I work really hard and I believe that I also do my job well. But recently, I have felt like my team leader is being unfair to me for no reason. It appears that he is nice to my co-workers, but not me. I figure he is mad at me, but I didn't bother to find out why. I really love this company and I really love working there. But if my team leader continues to be unfair then I have no option other than leaving. How can I fix this? EDIT: The other day he called me into his office and wanted to see my work in the afternoon (Yes, in my country, at summer season after 5PM is afternoon. My office begins at 8AM. And I'm not saying I've problems to work after 5PM). At the time I was facing a weird runtime error and I was pretty tired. I explained the situation to him. Then he found a small logical error in my code and asked me why I didn't fix this. I told him I was trying to resolve this runtime error and that I was sure that this logical error had nothing to do with the runtime error. He then proceeded to yell at me. After fixing the logical error that runtime error was still there. This is not the only occasion he has been unfair to me. I'm saying is being unfair because he doesn't do this kind of thing to other developers when they do really silly mistakes.

• OpenGL Drawing textured model (OBJ) black texture

  - by andrepcg

  I'm using OpenGL, Glew, GLFW and Glut to create a simple game. I've been following some tutorials and I have now a good model importer with textures (from ogldev.atspace.co.uk) but I'm having an issue with the model textures. I have a skybox with a beautiful texture as you can see in the picture That weird texture behind the helicopter (model) is the heli model that I've applied on purpose to that wall to demonstrate that specific texture is working, but not on the helicopter. I'll include the files I'm working on so you can check it out. Mesh.cpp - http://pastebin.com/pxDuKyQa Texture.cpp - http://pastebin.com/AByWjwL6 Render function + skybox - http://pastebin.com/Vivc9qnT I'm just calling mesh->Render(); before the drawSkyBox function, in the render loop. Why is the heli black when I can perfectly apply its texture to another quad? I've debugged the code and the mesh-render() call is correctly fetching the texture number and passing it to the texture-bind() function.

• Create a fast algorithm for a "weighted" median

  - by Hameer Abbasi

  Suppose we have a set S with k elements of 2-dimensional vectors, (x, n). What would be the most efficient algorithm to calculate the median of the weighted set? By "weighted set", I mean that the number x has a weight n. Here is an example (inefficient due to sorting) algorithm, where Sx is the x-part, and Sn is the n-part. Assume that all co-ordinate pairs are already arranged in Sx, with the respective changes also being done in Sn, and the sum of n is sumN: sum <= 0; i<= 0 while(sum < sumN) sum <= sum + Sn(i) ++i if(sum > sumN/2) return Sx(i) else return (Sx(i)*Sn(i) + Sx(i+1)*Sn(i+1))/(Sn(i) + Sn(i+1)) EDIT: Would this hold in two or more dimensions, if we were to calculate the median first in one dimension, then in another, with n being the sum along that dimension in the second pass?

• Should I tell a departed coworker about their "sev 1" defect?

  - by noahz

  I had a co-worker leave our company recently. Before leaving, he coded a component that had a severe memory leak that caused a production outage (OutOfMemoryError in Java). The problem was essentially a HashMap that grew and never removed entries, and the solution was to replace the HashMap with a cache implementation. From a professional standpoint, I feel that I should let him know about the defect so he can learn from the error. On the other hand, once people leave a company, they often don't want to hear about legacy projects that they have left behind for bigger and better things. What is the general protocol for this sort of situation?

• Windows 7 Skype shifts audio to speakers

  - by Greg Reynolds

  I have noticed a strange feature on my Dell Latitude running Windows 7 and Skype. When I am listening to music on the headphones, and Skype rings, then the audio I was listening to is redirected to the computer speakers, while Skype takes over the headphones. This is infuriating as my co-workers are treated to 1 second snippets of whatever rubbish I have on at the time. Any ideas on how to stop this happening? I messed with some of the settings on Skype, but nothing seems to make any difference.

• PNG file loading error in ImageMagick

• How to know if my nginx is in good health?

  - by Howard

  I am running a nginx on EC2 (m1.small) for SSL termination. I am using 2 workers on Ubuntu, with latest nginx (stable), the network throughput is around 2Mbps and system load average is around 2 to 3. I am wondering if this system is in good health for now, e.g. what is the queue length (I know nginx can handle a lot of concurrent request, but I mean before the request is being served, how many of them need to wait before being served) what is the average queue time for a given request to be served. I want to know because if my nginx is cpu bounded (e.g. due to SSL), I will need to upgrade to a faster instance. My current nginx status Active connections: 4076 server accepts handled requests 90664283 90664283 104117012 Reading: 525 Writing: 81 Waiting: 3470

• Concurrency Utilities for Java EE 6: JSR 236 Rebooting

  - by arungupta

  JSR 166 added support for concurrency utilities in the Java platform. The JSR 236's, a.k.a Concurrency Utilities for Java EE, goal was to extend that support to the Java EE platform by adding asynchronous abilities to different application components. The EG was however stagnant since Dec 2003. Its coming back to life with the co-spec lead Anthony Lai's message to the JSR 236 EG (archived here). The JSR will be operating under JCP 2.8's transparency rules and can be tracked at concurrency-spec.java.net. All the mailing lists are archived here. The final release is expected in Q1 2013 and the APIs will live in the javax.enterprise.concurrent package. Please submit your nomination if you would like to join this EG.

• HCM is Alive and Well in APAC

  - by Row Henson

  I just returned from a 5 country tour on “Rethinking HR” where Oracle hosted breakfast and lunch executive seminars to the most senior HR practitioners in 5 cities in these major markets in APAC. While I have done many of these “road shows” in the past, I was most impressed with the response we received during this trip. I’m sure the execution of our marketing and sales teams had lots to do with the turnout, but I’d also like to think that this region is primed for applications that help with the talent dilemma faced by many organizations today in this part of the world and are excited about the offerings Oracle provides to help our customers attract, develop, retain and analyze their human capital. For these type of events, we normally expect 25-30 companies in attendance with a drop-off rate of around 15%. In all 5 cities, we had standing room only with an average attendance of 50 people from 30+ companies. Interestingly enough, in 3 of the 5 cities we had people show up that were turned down during registration, for lack of room – so we actually exceeded our registration. This was the case in Canberra – Australia’s capital – with over 70 attendees. Unusual indeed! During my presentation I referenced several studies which highlight how this region is primed for support in looking at talent in the future as high growth creates talent shortages and talented workers see opportunities outside of their current employers. A Deloitte study shows that 61% of respondents in APAC expect significant or moderate talent shortages over the next year (compared to 45% and 31% for the Americas and EMEA respectively). Please accept my thanks to all who arranged and orchestrated this time in APAC. While my body was quite tired from the hectic schedule, my mind was energized with the interest and interaction.

• Naming convention: Final fields (not static)

  - by Zeeker

  Today I had a discussion with a co-worker about the naming of final fields in Java classes. In his opionion final fields should also be considered constants since their values won't change after the creation of the instance. This would lead to the following naming convention for final fields: public class Foo { private static final String BLA_BLA = "bla"; private final String BAR_BATZ; ... } In my opinion only static final fields should be considered constants while fields which are only final should follow the usual camelCase naming convention. public class Foo { private static final String BLA = "bla"; private final String barBatz; ... } Now I'm a bit uncertain since he is a far more experienced programmer than I am and I usually agree with his opinions and consider him a very good developer. Any input on this?

• How to show the right country domain in Google Places?

  - by Baumr

  Background A site has multiple ccTLDs: example.com for the US, example.co.uk for UK users, example.de for Germans, etc. Googling for certain city keywords will return rich snippets with a list of Google Places: Problem When searching on Google Germany, the domain for US users (example.com) appears instead of the corresponding ccTLD (example.de). This is not good user experience, as users would most likely like to book on a site localized for them (e.g. language and currency). Question What solutions are there? Is it possible to return different ccTLDs in rich snippets for Google searches in Germany/UK? Ideas Would implementing the hreflang annotation resolve this? What about entering multiple corresponding URLs in the structured data markup?

• Ways to find a tutor for 1st year University student

  - by Craig H

  I tried searching here (and SO) without much luck. I also stared at the yellow box to the right and think this question is relatively on topic and can be answered. A co-worker asked me if I had any suggestions for how to find a tutor for his son. In this specific case, it was for Eclipse and Java, but it got me thinking about good general strategies one could use in situations like this. He preferred a local 1-to-1, but I suppose online might be a reasonable (or perhaps more likely) alternative. Any suggested strategies?

• Play videos with libwebkit in Ubuntu 11.10 server

  - by Luis Fagundes

  I'm using libwebkit (with python-webkit) to render a page that plays a video. This application works fine in a Ubuntu 11.04 Desktop, Nvidia card and lots of libraries and software installed, but in a fresh Ubuntu 11.10 Server with intel 82945G/GZ card the video does not play. I guess either some codec package is missing or it's a driver problem. What could be missing for this to play? I'm trying with this video: http://video.eustasy.co.uk/480/ EDIT: doesn't look like a driver problem. With chromium I can play the video, but with libwebkit + python-webkit the video just shows the first frame and doesn't play. Any hints on what package could be missing? SOLVED: apparently it had to do with lack of audio. While chrome would play the video with no sound, libwebkit wouldn't start video. Adding user to audio and video groups solved the problem.

• How to react to an office harassment based on my profession ? [closed]

  - by bob from jersey

  A lot of my co-workers (not developers, people from the other departments) who are framing me in the classical "nerd" stereotype, and with that acting disturbing towards me. Of course they are not aggressive or anything, since we are in a work environment having rules on it's own, plus we are all grownups now, but they are on a "quite war" against me (not particularly against me, they are against all developers, but I am the only one who dares to speak about it). I hear names, "nerd", "geek", "cyborg", "outsider" and so on, it's really inappropriate. Of course, nothing is said in our faces, but, you know, "you hear things over". Also this general feeling of "them not liking us at all" can be sensed in the air all the time. And while it is not a problem for a few weeks, a larger duration of constant office harassment (going for months now), can be really annoying and can cause a serious drop in the development performance, which will (inevitably) lead to problems with the management (maybe getting me fired). I want to know, should I continue with my current defensive strategy (passively ignoring their inappropriate labels) or should I switch into a more aggressive maneuvers, like giving them logical reasons why their antisocial behavior should be banned?

• What should you include in a development approach document?

  - by Liggy

  I'm in the middle of co-producing a "development approach" document for off-shore resources as they ramp up onto our project. The most recent (similar) document our company has used is over 80 pages, and that does not include coding standards/conventions documents. My concern is that this document will not be consumable and will therefore fail. What should be in a development approach document? Are there any decent guidelines on this topic? EDIT: The development approach document should detail the practices and techniques that will be used by software developers while software is designed, built, and tested.

• Map, Set use cases in a general web app

  - by user2541902

  I am currently working on my own Java web app (to be shown in interview to get a Java job). So I've not worked on Java in professional environment, so no guidance. I have database, entity classes, JPA relationships. Use cases are like, user has albums, album has pics, user has locations, location has co-ordinates etc. I used List (ArrayList) everywhere. I can do anything with List and DB, get some entry, find etc. For example, I will keep the list of users in List, then use queries to get some entry (why would I keep them in Map with id/email as key?). I know very well the working and features, implementing classes of Map, Set. I can use them for solving some algorithm, processing some data etc. In interviews, I get asked have you worked with these, where have you used them etc. So, Please tell me cases where they should be used (DB or any popular real use case).

• Employers and intellectual property 2

  - by Rick

  I have a question about intellectual property, I am currently a manager in a small manufacturing firm. The owners are driven by greed and don't appreciate the development process of complex machinery and are happy just to send things out half done. I on the other hand think that it should be done properly as breakdown in the field can be costly, embarrassing. They seem to have all of us running around doing most of the work out of hours using the attitude of "Be grateful to have a job" yet no one has a contract or any security or any agreement in place. For a couple of the projects i am using PLC's and doing the code in my own time and the testing during company time, and i am aware that they cannot support their own machines if i left, but as i created the code in my own time who owns it? The have asked my to put in a shutdown code for a maintenance request after a given length of time, could this be classed as criminal damage or anything illegal apart from immoral? (we sell the machines with 12 month warrantee, shut down after) But as time goes on I'm getting rather fed up of the companies attitude toward the client. I am considering keeping the clients as my own and get them to contact me directly In the shutdown code. By doing something like this is a trial version contact me for a full license? I wouldn't feel bad for my current employer as he is not afraid to S***t on people as he has been evolved in numerous law suits and has over 30 failed companies leaving people and customers high and dry, we have took the company this far on the reputation of the workers and and i can see things heading like all the other companies he has owned and taking our reputations with him. So i suppose now i have set the scene, if i code into it to contact me directly in the shutdown could there be any legal impact on me, as i rightly or wrongly think i own the code and designs? Cheers R

• Logitech Microphone (AK5370) inaudible volume

  - by Iain Lane

  I bought this microphone from Amazon last week. It's detected just fine in 12.10. I can see it in the sound preferences. The problem is that the volume is so low as to be inaudible, even when turned up to maximum in this dialog. It is working, as I can see that the meter responds to noise, but it's just too low. alsamixer's control is the same, so that doesn't help. I tried messing around in pulseaudio too, but to no avail.

• Can WebGL be used to create a tile-based multi-layer scrolling platform game?

  - by Nicholas Hill

  I've found WebGL (based on OpenGL) to be a fiendish and unforgiving framework for those learning to write HTML5-based games. Despite the presence of many examples on how to get started, I'm really struggling to understand how I could simply load a bunch of images and render them to a canvas quickly using WebGL. My specific scenario involves trying to render a map using a bespoke but simple multi-layered tile engine, where each value in a three dimensional array points to the image to use for that location in the rendered image. Think "Sonic the Hedgehog" via tilesets, tiles, maps, layers, sprites etc. Can anyone enlighten me: 1) How can I load an image that I can use as a texture in WebGL? 2) How can I dynamically select an image at run time and draw it at any co-ordinate, that I also select at run time?

• Best practices for Persona development

  - by user12277104

  Over the years, I have created a lot of Personas, I've co-authored a new method for creating them, and I've given talks about best practices for creating your own, so when I saw a call for participation in the OpenPersonas project, I was intrigued. While Jeremy and Steve were calling for persona content, that wasn't something I could contribute -- most of the personas I've created have been proprietary and specific to particular domains of my employers. However, I felt like there were a few things I could contribute: a process, a list of interview questions, and what information good personas should contain. The first item, my process for creating data-driven personas, I've posted as a list of best practices. My next post will be the list of 15 interview questions I use to guide the conversations with people whose data will become the personas. The last thing I'll share is a list of items that need to be part of any good persona artifact -- and if I have time, I'll mock them up in a template or two.
