  • SQLAuthority Guest Post – Lessons from Life and Work by Srini Chandra (Author of 3 Lives, in search of bliss)

    - by pinaldave
    Work and life are confusing terms together. How can one consider work outside of life. Work should be part of life or are we considering ourselves dead when we are at work. I have often seen developers and DBA complaining and confused about their job, work and life. Complaining is easy and everyone can do. I have heard quite often expression – “I do not have any other option.” I requested Srini Chanda (renowned author of Amazon Best Seller 3 Lives, in search of bliss (Amazon | Flipkart) to write a guest post on this subject which developer can read and appreciate. Let us see Srini’s thoughts in his own words. Each of us who works in the technology industry carries an especially heavy burden nowadays. For, fate has placed in our hands an awesome power to shape our society and its consciousness. For that reason, we must pay more and more attention to issues of professionalism, social responsibility and ethics. Equally importantly, the responsibility lies in our hands to ensure that we view our work and career as an opportunity to enlighten and lift ourselves up. Story: A Prisoner, 20 years and a Wheel Many years ago, I heard this story from a professor when I was a student at Carnegie Mellon. A man was sentenced to 20 years in prison. During his time in prison, he was asked to turn a wheel every day. So, every day he turned the wheel. At times, when he was tired or puzzled and stopped turning the wheel, he would be flogged with a whip. The man did not know anything about the wheel other than that it was placed outside his jail somewhere. He wondered if the wheel crushed corn or if it ground wheat or something similar. He wondered if turning the wheel was useful to anyone. At the end of his jail term, he rushed out to see what the wheel was doing. To his disappointment, he found that the wheel was not connected to anything. All these years, he had been toiling for nothing. He gave a loud, frustrated shout and dropped dead. How many of us are turning wheels wondering what it is connected to? How many of us have unstated, uncaring attitudes towards our careers? How many of us view work as drudgery, as no more than a way to earn that next paycheck? How many of us have wondered about the spiritually uplifting aspect of work? Can a workforce that views work as merely a chore, be ethical? Can it produce truly life enhancing technology? Can it make positive contributions to the quality of life of a society? I think not. Thanks to Pinal and you, his readers, for giving me this opportunity to share my thoughts in a series of guest posts. I’d like to present a few ways over the next few weeks, in which we can tap into the liberating potential of work and make our lives better in the process. Now, please allow me to tell you another version of the story that the good professor shared with us in the classroom that day. Story: A Prisoner, 20 years, a Wheel and the LIFE A man was sentenced to 20 years in prison. During his time in prison, he was asked to turn a wheel every day. So, every day he turned the wheel. At first, his whole body and mind rebelled against his predicament. So, his limbs grew weary and his mind became numb and confused. And then, his self-awareness began to grow. He began to wonder how he came to be in the prison in the first place. He looked around and saw all his fellow prisoners also turning the wheel. His wife, his parents, his friends and his children – they were all in the prison too, and turning their own wheels! He began to wonder how this came about. As he wondered more and more, he began to focus less on his physical drudgery and boredom. And he began to clearly see his inner spirit which guided him in ways that allowed him to see the world with a universal view. His inner spirit guided him towards the source of eternal wisdom and happiness. He began to see the source of happiness in everything around him – his prison bound relationships, even his jailers and in his wheel. He became a source of light to those around him. His wheel jokes and humor infected them with joy and happiness. Finally, the day came for his release from jail. He walked calmly outside the jail and laughed aloud when he saw that the wheel was not connected to anything. He knelt down, kissed it and thanked it for the wisdom it taught him. Life is the prison. The wheel is your work. Both are sacred. Both have enormous powers to teach us wisdom and bring us happiness. Whether we allow them to do so, is a choice we have to make. Over the next few weeks, I hope to share with you a few lessons that I have learnt at the wheel in my two decades of my career (prison). Thank you for reading, and do let me know what you think.

  • How do you get aware of new tools?

    - by Konstantin Petrukhnov
    How do you get aware of new tools (libraries, applications, etc)? This question is only about "getting aware" that some tool exist and could be used. Learning and trying is different issue. Right now I get most awareness from stackexchange and freshmeat sites. But I wonder if there are more efficient way. E.g. 80% of freshmeat projects are no-use for me, but it reasonable overhead, because tools that I find trough it save me days or even weeks. Here are some related, but a bit different questions: How much time do you invest in exploring new technology? How to become aware of new languages, techniques and methodologies? What website are you using most to keep you updated on software development?

  • Bless doesn't fix white boot screen boot delay for single-boot Xubuntu 14.04 on Macbook 4,1

    - by elephant
    I still have a 30-second delay on the white boot-up screen before Xubuntu loads after trying various combinations of bless --device as recommended here: https://help.ubuntu.com/community/MactelSupportTeam/AppleIntelInstallation#Avoid_long_EFI_wait_before_GRUB I wonder if anyone has experienced this before, or can point me to some good steps for troubleshooting this issue? I have cycled my macbook dozens of times, it would be great to be able to boot quicker. I am single-booting Xubuntu 14.04 (no Mac OSX partitions or any other OS, just a GRUB partition at sda1, a main partition at sda2, and a swap at the end of the drive). Suggestions very appreciated.

  • Creating and Using a jQuery Plug-in in ASP.NET Web Forms

    - by bipinjoshi
    Developers often resort to code reuse techniques in their projects. As far as ASP.NET framework server side programming is concerned classes, class libraries, components, custom server controls and user controls are popular code reuse techniques. Modern ASP.NET web applications no longer restrict themselves only to server side programming. They also make use of client side scripting to render rich web forms. No wonder that Microsoft Visual Studio 2010 includes jQuery library by default as a part of newly created web site. If you are using jQuery for client side scripting then one way to reuse your client side code is to create a jQuery plug-in. Creating a plug-in allows you to bundle your reusable jQuery code in a neat way and then reuse it across web forms. In this article you will learn how to create a simple jQuery plug-in from scratch. You will also learn about certain guidelines that help you build professional jQuery plug-ins.http://www.bipinjoshi.net/articles/aae84a03-b4a8-477d-b087-5b7f42935220.aspx

  • Live Meeting error: malformed email address... or IS IT???

    - by PeterBrunone
    During a remote SharePoint training session this morning, Live Meeting presented one of our instructors with the following gem:  "An attendee email address is malformed".  This was particularly troubling since a wizard took care of adding all the entries, and they looked correct (even after being sifted through my character analysis tool).As it turns out, the addresses were indeed correct.  As sometimes happens, though, at the line breaks, it looked like there was no space between the semicolon and the following email address.  Since I'm a member in good standing of the "I wonder what this button does" school of thought, I added an extra space after each of these cramped little semicolons -- and the invitation executed flawlessly.Coincidence?  Maybe... but you can bet I'm going to keep trying dumb stuff like that when the error message doesn't make sense.  Think of it as the tech support equivalent of "Ask a silly question..."

  • The Infinite Jukebox Creates Seamless Loops from Your Favorite Songs

    - by Jason Fitzpatrick
    Why limit yourself to simply listening to a song on repeat when The Infinite Jukebox can use algorithms to turn your song into a seamless and never ending tune? Unlike simply looping a song from the start to the end over and over, The Infinite Jukebox analyzes the song and looks for spots where it can seamlessly transition from one point in the song to a previous point to create a sense of never-ending music. Some songs worked better than others in our testing–Superstition by Stevie Wonder, for example, worked flawlessly but Gangnam Style by Psy got stuck in a short loop that sounded unnatural. Hit up the link below to play with already uploaded MP3s or upload your own to take it for a spin.

  • is it better to spend my free time mastering a language I work with or learning a new one?

    - by edthethird
    I work full time on an android project and am very comfortable with both java and the android framework. On a good day, I would rate my abilities at an 8, and maybe a 7 on a bad day. I've recently found myself with more free time then I'm used too, so I have been working on a lot of personal projects. I am beginning to wonder what others think about this; is it worth my time to continue experimenting and pushing Android, or would I be better off learning another language? What do you all think about this? What would you do with more free time and energy than you know what to do with?

  • Software development life cycle in the industry

    - by jiewmeng
    I am taking a module called "Requirements Analysis & Design" in a local university. Common module, I'd say (on software development life cycle (SDLC) and UML). But there is a lot of things I wonder if they are actually (strictly) practiced in the industry. For example, will a domain class diagram, an not anything extra (from design class), be strictly the output from Analysis or Discovery phase? I'm sure many times you will think a bit about the technical implementation too? Else you might end up with a design class diagram later that is very different from the original domain class diagram? I also find it hard to remember what diagrams are from Initiation, Discovery, Design etc etc. Plus these phases vary from SDLC to SDLC, I believe? So I usually will create a diagram when I think will be useful. Is it the wrong way?

  • How to reset settings when Unity won't finish booting?

    - by Emre
    I have a new 12.04 installation and I messed things up after trying to move /home to an NTFS partition, which I later learned was a bad idea. I removed references to the NTFS partition on fstab and created new users on the ext4 / partition. Now I can't get Unity to start up properly for any user. I get the GUI with only three Launch icons (none of which are clickable) and no bar at the top. The keyboard seems to the nonfunctional after I enter my credentials. The interesting thing is that I can boot when I go through recovery mode and select resume. I wonder whether I am creating the new users properly. What is the correct protocol for doing so in order to ensure that they can run Unity?

  • Why is using C++ libraries so complicated?

    - by Pius
    First of all, I want to note I love C++ and I'm one of those people who thinks it is easier to code in C++ than Java. Except for one tiny thing: libraries. In Java you can simply add some jar to the build path and you're done. In C++ you usually have to set multiple paths for the header files and the library itself. In some cases, you even have to use special build flags. I have mainly used Visual Studio, Code Blocks and no IDE at all. All 3 options do not differ much when talking about using external libraries. I wonder why was there made no simpler alternative for this? Like having a special .zip file that has everything you need in one place so the IDE can do all the work for you setting up the build flags. Is there any technical barrier for this?

  • why not use unmanaged safe code in c#

    - by user613326
    There is an option in c# to execute code unchecked. It's generally not advised to do so, as managed code is much safer and it overcomes a lot of problems. However I am wondering, if you're sure your code won't cause errors, and you know how to handle memory then why (if you like fast code) follow the general advice? I am wondering this since I wrote a program for a video camera, which required some extremely fast bitmap manipulation. I made some fast graphical algorithms myself, and they work excellent on the bitmaps using unmanaged code. Now I wonder in general, if you're sure you don't have memory leaks, or risks of crashes, why not use unmanaged code more often ? PS my background: I kinda rolled into this programming world and I work alone (I do so for a few years) and so I hope this software design question isn't that strange. I don't really have other people out there like a teacher to ask such things.

  • Is making my own copyright licence safe?

    - by abcd
    I've seen various open source libraries (actually I've seen it for assets as well) having a home-baked license in the following manner : SomeGuy's License:1. You can use this code freely in commercial projects and modify it as you wish, but not sell it2. If you want to sell a modified version, drop me an email first, or give credits to me Edit: The above example is ambiguous, so I am giving another one, I want to know if 3 lines of license will hold some ground: SomeGuy's License:1. You can use this code in a commercial project as a 3rd party library2. You can't sell it as a derivative work I know that such license is not polished at all, for example the Creative Commons set of licenses seem to be short, but actually have some large legal stuff underneath it, but I wonder if at least some level of protection can be gained with a hobby license like that ? My question is, could this hold any ground in the court, or would the corporative lawyers of the company X tear it apart ?

  • Inspecting the model in a Rails application

    - by Matt Sherman
    I am learning some Ruby on Rails, and am a newbie. Most of my background is in ASP.net MVC on the back end. As I play with a basic scaffold project, I wonder about this case: you jump into an established Rails project and want to get to know the model. Based on what I have seen so far (again, simple scaffold), the properties for a given class are not immediately revealed. I don't see property accessors on the model classes. I do understand that this is because of the dynamic nature of Ruby and such things are not necessary or even perhaps desirable. Convention over code, I get that. (Am familiar with dynamic concepts, mostly via JS.) But if I am somewhere off in a view, and want to quickly know whether the (eg) Person object has a MiddleName property, how would I find that out? I don't have to go into the migrations, do I?

  • When is a Use Case layer needed?

    - by Meta-Knight
    In his blog post The Clean Architecture Uncle Bob suggests a 4-layer architecture. I understand the separation between business rules, interfaces and infrastructure, but I wonder if/when it's necessary to have separate layers for domain objects and use cases. What added value will it bring, compared to just having the uses cases as "domain services" in the domain layer? The only useful info I've found on the web about a use case layer is an article by Martin Fowler, who seems to contradict Uncle Bob about its necessity: At some point I may run into the problems, and then I'll make a Use Case Controller - but only then. And even when I do that I rarely consider the Use Case Controllers to occupy a separate layer in the system architecture. Edit: I stumbled upon a video of Uncle Bob's Architecture: The Lost Years keynote, in which he explains this architecture in depth. Very informative.

  • multithreading problem with Nvidia PhysX

    - by xcrypt
    I'm having a multithreading problem with Nvidia PhysX. the SDK requires that you call Simulate() (starts computing new physics positions within a new thread) and FetchResults(waits 'till the physics computations are done). Inbetween Simulate() and FetchResults() you may not 'compute new physics' It is proposed (in a sample) that we create a game loop as such: Logic (you may calculate physics here and other stuff) Render + Simulate() at start of Render call and FetchResults at end of Render() call However, this has given me various little errors that stack up: since you actually render the scene that was computed in the previous iteration in the game loop. I wonder if there's a way around this? I've been trying and trying, but I can't think of a solution...

  • Learning about security and finding exploits

    - by Jayraj
    First things first: I have absolutely no interest in learning how to crack systems for personal enrichment, hurting other people or doing anything remotely malicious. I understand the basis of many exploits (XSS, SQL injection, use after free etc.), though I've never performed any myself. I even have some idea about how to guard web applications from common exploits (like the aforementioned XSS and SQL injection) Reading this question about the Internet Explorer zero-day vulnerability from the Security SE piqued my curiosity and made me wonder: how did someone even find out about this exploit? What tools did they use? How did they know what to look for? I'm wary about visiting hacker dens online for fear of getting my own system infected (the Defcon stories make me paranoid). So what's a good, safe place to start learning?

  • Backup, clean install and restore

    - by Tony Martin
    Due to the route I came into Ubuntu I now have 12.10 upgraded from 12.04 on an NTFS file system. I've invested a lot of time getting everything as I want it, vis packages installed and settings, etc. I wonder if there is an easy method of: 1 Backing up the whole system so that I can; 2 Do a squeaky clean install of 12.10 on ext4 with bells and whistles then; 3 Restore my backup so that my system behaves as it did before the reinstall? Sorry if this seems terribly obvious, but I don't want to find all the problems when it's too late. TIA.

  • How to draw a global day night curve

    - by Lumis
    I see many applications which have world-clock map, and I would like to make my own to enhance some of my mobile apps. I wonder if anybody has any knowledge where to start, how to draw a curved shadow representing the dawn and the sunset on the globe. See the example: http://aa.usno.navy.mil/imagery/earth/map?year=2012&month=6&day=19&hour=14&minute=47 I think that this curve goes up and down and creates an artic day/night etc Perhaps there is some acceptable approximation formula without a need to load data for each our and each global parallel and meridian...

  • Prefer algorithms to hand-written loops?

    - by FredOverflow
    Which of the following to you find more readable? The hand-written loop: for (std::vector<Foo>::const_iterator it = vec.begin(); it != vec.end(); ++it) { bar.process(*it); } Or the algorithm invocation: #include <algorithm> #include <functional> std::for_each(vec.begin(), vec.end(), std::bind1st(std::mem_fun_ref(&Bar::process), bar)); I wonder if std::for_each is really worth it, given such a simple example already requires so much code. What are your thoughts on this matter?

  • Solid principles vs YAGNI

    - by KeesDijk
    When do the SOLID principles become YAGNI? As programmers we make trade-offs all the time, between complexity, maintainability, time to build and so forth. Amongst others, two of the smartest guidelines for making choices are in my mind the SOLID principles and YAGNI. If you don't need it; don't build it, and keep it clean. Now for example, when I watch the dimecast series on SOLID, I see it starts out as a fairly simple program, and ends up as a pretty complex one (end yes complexity is also in the eye of the beholder), but it still makes me wonder: when do SOLID principles turn into something you don't need? All solid principles are ways of working that enable use to make changes at a later stage. But what if the problem to solve is a pretty simple one and it's a throwaway application, then what? Or are the SOLID principles something that always apply? As asked in the comments: Solid Principles YAGNI

Some people don't make test cases and just develop the way their senior have done in their projects. I am facing lot problems like object dependencies (when want to test method which persist A object i have to first persist B object since A is child of B). Please suggest some good books or sites preferably for learning design pattern for unit test cases. Or reference to some good source code or some discussion for Dos and Donts will do wonder.

  • Where does the URL parameter "?chocaid=397" come from?

    In Google Webmaster Tools, I noticed that my front page was indexed two times: example.com/ example.com/?chocaid=397 I know that I could fix this with the use of link type canonical, but I wonder: Where does this parameter come from? There are various sites that have pages indexed with this very parameter/value: https://duckduckgo.com/?q=chocaid%3D397. I looked for similarities between these sites. but couldn't find a conclusive one: It's often the front page, but not in every case. Some are NSFW, but not all. When one domains' URL has this parameter, often other subdomains of the same domain have it, too. Examples Wikipedia entry Microsoft Codeplex
