• My Latest Hare-Brained Scheme

  - by Liam McLennan

  I have not had a significant side project for a while but I have been working on a product idea. Its an analytics application that analyses twitter data and reports on market sentiment. The target market is companies who want to track trends in consumer sentiment. My idea is to teach the application to divide relevant tweets into ‘positive’ and ‘negative’ categories. If the input was the set of tweets featuring the word ‘telstra’ the application would find the following tweet:   and put it in the ‘negative’ category. Collecting data in this fashion facilitates the creation of graphs such as: which can then be correlated against events, such as a share offer or new product release. I may go ahead and build this, just because I am a programmer and it amuses me to do so. My concerns are: There  is no market for this tool There is a market, but I don’t understand it and have no way to reach it.

• creating a google wave clone using php/mysql/jquery

  - by jeansymolanza

  seasons greetings to all. i have a question that has been rather bugging me as of late. does anyone know how one can create a google wave clone using php/mysql/jquery as primary points of development. any ideas on how this might be possible and recommend any starting points? i have some time off work and it would be an interesting project to undertake as i want to use it in an e-learning framework next year. i will be testing the product on a XAMPP local server. i understand some of the technologies that google wave using but i am rather curious as to how these can be developed to a decent standard using php/mysql/jquery (i mention these three because i am quite adept at them). any links to resources best suited to an intermediate programmer would be appreciated. many thanks and God bless. so far i have this: http://konrness.com/javascript/google-wave-style-scroll-bar-jquery-plugin/

• Is it worth being computer languages polyglot?

  - by Anton Barkowski

  You can often hear that programmers should learn many different languages to improve themselves. I still go to school and don't have big programming experience (a little more than year). But what was noble intention to improve programming skills turned into some kind of OCD: I feel that I won't calm down until I learn all relatively known programming languages. And here is question itself: Will being programming languages polyglot actually help you (And I don't mean usual "Programmer should know at least all paradigms", I mean really all languages you usually hear about)? Does anybody have similar experience? Does it help with job/skills/career? How often are you able to apply those skills?

• Best keyboard drawer for programmers?

  - by David Pfeffer

  I'm a programmer with pretty severe neck problems. I program with three monitors, and I've found that my desk's short depth causes me to have to rotate my neck too much to see the "wing" screens. I can't get a deeper desk due to space restrictions. I'm looking for a keyboard drawer that can be installed onto a desk. However, I like the height of the keyboard on the desk. I'd like a drawer that is extremely low-profile/slim. My keyboard is less than 1" tall, so it'll fit pretty much anywhere. My ideal product would slide out from under my desk and "pop up" so that its surface is even with the desk. Does anything slim and nice like this exist? I'll even consider replacing the desk if a desk exists with this built-in.

• Is it possible to create and distribute an app for the BlackBerry Playbook that doesn't go into App World?

  - by Drackir

  My company is looking to create an app that we'll use internally on several (about 20) BlackBerry Playbooks. We don't want it to be put up on App World because it's just an internal application. I'm wondering if there are any: Costs involved with this outside of paying a programmer to develop it - i.e. Are there any license fees, deployment fees, etc. License issues involved with deploying the app to multiple Playbooks without deploying it to App World Limitations on functionality of the app Other things we should be taking into consideration If it matters, the app will be collecting information and downloading it to a computer via USB.

• Which Java web framework do you recommend for intranet webapp (not content website)?

  - by pregzt

  I'm about to start development of small purpose build intranet web application for small software vendor. It will be administration console of the server managing licenses for off-the-shelf software installed by users. There will be a few users who need to be able to sign in, issue a batch of license codes, revoke some, renew outdated, resolve issues, etc. Bear in mind that my customer requires Java for this solution. I'm seasoned Java programmer and before I used different frameworks to implement webapps, mainly Apache Struts in the past and Spring MVC recently. I was wondering what else could you recommend for such specific intranet webapp. I looked at using Google Web Toolkit (possibly with SmartGWT) Ext JS for fancy widgets in UI and REST back-end in SpringMVC SpringMVC with JQueryUI Could you please think of any piece of recommendation with regard to the choice I'm going to made?

• Is the C programming language still used?

  - by Pankaj Upadhyay

  I am a C# programmer, and most of my development is for websites along with a few Windows application. As far as C goes, I haven't used it in a long time, as there was no need to. It came to me as a surprise when one of my friends said that she needs to learn C for testing jobs, while I was helping her learn C#. I figured that someone would only learn C for testing only if there is development done in C. In my knowledge, all the development related to COM and hardware design are also done in C++. Therefore, learning C doesn't make sense if you need to use C++. I also don't believe in historic significance, so why waste time and money in learning C? Is C is still used in any kind of new software development or anything else?

• Is there any one standard framework for developing Python GUI apps.?

  - by RPK

  There are so many frameworks for writing GUI application using Python. But is there any one key standard framework? For example we have a bundle of .NET/C# on Visual Studio. I am thinking in other perspectives also. In future if I give an interview for a Python programmer job, which GUI framework will be considered? I also wonder, there is no IDE that integrates the GUI and Python language. Choice of flavor is good but over-choice becomes a distraction.

• No SQLCompact Edition Support IN VS 2013

  - by James Izzard

  Firstly apologies if this is a poor question - I am an engineer not a programmer. I have spent time moving from Visual Basic to C#. I have started C#/SQL tutorials. I have noticed VS 2013 has stopped supporting the compact edition database normally used for standalone desktop apps. Somebody has kindly written a plugin to re-implement support. I have also noticed a belief circulating that SQLite is to replace the compact edition. Would anybody be able to advise if this was accurate - I am slightly confused as to which database is best suited for desktop app development inside VS 2013. Any comment greatly appreciated. Cheers James

• Books and stories on programming culture, specifically in the 80's / early 90's

  - by Ivo van der Wijk

  I've enjoyed a number of (fiction/non-fiction books) about hacker culture and running a software business in the 80's, 90's. For some reason things seemed so much more exciting back then. Examples are: Microserfs (Douglas Coupland) Accidental Empires (Robert X. Cringely Almost Pefect (W.E. Peterson, online!) Coders at Work (Peter Seibel) Today I'm an entrepeneur and programmer. Back in the 80's a I was a young geek hacking DOS TSR's and coding GWBasic / QBasic. In the 90's I was a C.S. university student, experiencing the rise of the Internet world wide. When reading these books running a software business seemed so much more fun than it is nowadays. Things used to be so much simpler, opportunities seemed to be everywhere and the startups seemed to work with much more real problems (inventing spreadsheets, writing word processors in assembly on 6 different platforms) than all our current web 2.0 social networking toys. Does anyone share these feelings? Does anyone have any good (personal) stories from back then or know of other good books to read?

• «Le projet de loi des droits du développeur» : quelles conditions doivent remplir les entreprises pour que le développeur puisse réussir ?

  « Le projet de loi des droits du développeur » quels éléments fondamentaux doivent fournir les entreprises pour que le développeur puisse réussir dans son métier ? Le métier de développeur nécessite un environnement adapté, des outils et un certain confort pour un meilleur rendement. Cependant, plusieurs entreprises ne fournissent toujours pas au développeur les éléments essentiels dont il a besoin pour réussir. Je suis tombé sur un ancien billet de Jeff Atwood, illustre blogueur, intitulé « The Programmer's Bill of Rights » (projet de loi des droits du programmeur), qui propose un projet de loi pour la protection des droits des programmeurs en empêchant les entrepr...

• How do I approach large companies if I have a killer mobile game idea?

  - by Balázs Dávid

  I have an idea for a game that has potential, but I'm not a programmer. How do I tell this to development companies without having my idea stolen? All I want from the company is for somebody to watch a three minute long video presentation about my idea and if they see potential in it then we can talk about the details. I have already sent an e-mail to several big companies that have the expertise needed to code the game, they haven't answered me. Actually the idea is nothing fancy, no 3D, but fun and unique.

• Why should we use low level languages if a high level one like python can do almost everything? [closed]

  - by killown

  I know python is not suitable for things like microcontrolers, make drivers etc, but besides that, you can do everything using python, companys get stuck with speed optimizations for real hard time system but does forget other factors which one you can just upgrade your hardware for speed proposes in order to get your python program fit in it, if you think how much cust can the company have to maintain a system written in C, the comparison is like that: for example: 10 programmers to mantain a system written in c and just one programmer to mantain a system written in python, with python you can buy some better hardware to fit your python program, I think that low level languages tend to get more cost, since programmers aren't so cheaply than a hardware upgrade, then, this is my point, why should a system be written in c instead of python?

• Do programmers at non-software companies need the same things as at software companies?

  - by Michael

  There is a lot of evidence that things like offices, multiple screens, administration rights of your own computer, and being allowed whatever software you want is great for productivity while developing. However, the studies I've seen tend toward companies that sell software. Therefore, keeping the programmers productive is paramount to the company's profitability. However, at companies that produce software simply to support their primary function, programming is merely a support role. Do the same rules apply at a company that only uses the software they produce to support their business, and a lot of a programmer's work is maintainence?

• Redirect from https://mydomain.com to http://mydomain.com

  - by Charlie

  Many of my visitors have bookmarked my site already wtih https://mydomain.com. Under the bad advice of a programmer, I put my whole Joomla site under ssl. I do not sell anything or provide any member services. I asked him many times if it would slow my site down - he said it wouldn't. I knew it did, I've researched on this site and realized it does slow the site down because of no cache of the pages. Understood. Please, someone tell me how to get away from it now. I'm not sure how to approach this, should I add something to my htaccess or my main index.php file? I've looked all over the net, there is much advice for adding redirectives for going from http to https, but very few answers regarding the opposite of going from https to http. Thank you very much for your time. I appreciate it.

• Design patterns and multiple programming languages

  - by Eduard Florinescu

  I am referring here to the design patterns found in the GOF book. First, how I see it, there are a few peculiarities to design pattern and knowing multiple languages, for example in Java you really need a singleton but in Python you can do without it you write a module, I saw somewhere a wiki trying to write all GOF patterns for JavaScript and all the entries were empty, I guess because it might be a daunting task to do that adaptation. If there is someone who is using design patterns and is programming multiple languages supporting the OOP paradigm and can give me a hint on how should I approach design patterns. An approach that might help me in all languages I use(Java, JavaScript, Python, Ruby): Can I write good application without knowing exactly the GOF design patterns or I might need just some of them which might be crucial and if yes which one, are there alternatives to GOF for specific languages, and should a programmer or a team make their own design patterns set?

• LSP vs OCP / Liskov Substitution VS Open Close

  - by Kolyunya

  I am trying to understand the SOLID principles of OOP and I've come to the conclusion that LSP and OCP have some similarities (if not to say more). the open/closed principle states "software entities (classes, modules, functions, etc.) should be open for extension, but closed for modification". LSP in simple words states that any instance of Foo can be replaced with any instance of Bar which is derived from Foo and the program will work the same very way. I'm not a pro OOP programmer, but it seems to me that LSP is only possible if Bar, derived from Foo does not change anything in it but only extends it. That means that in particular program LSP is true only when OCP is true and OCP is true only if LSP is true. That means that they are equal. Correct me if I'm wrong. I really want to understand these ideas. Great thanks for an answer.

• How important is to sacriface your free time for accomplishing goals? [closed]

  - by Darf Zon

  I was reading a book about XP programming and about agile teams. While I was reading, I saw this scenario. I've never worked with a development team (just in school). So I would like what do you opine on this situation: Your boss has asked you to deliver software in a time that can only be possible to meet the project team asking if you want to work overtime without pay. All team members have young children. Discuss whether it should accept this request from your boss or should persuade the team to give their time to the organization rather than their families. What could be significant factors in the decision? As a programmer, you are offered an upgrade as project manager, but his feeling is that you can have a more effective contribution in a technical role in one administrative. Write when you should accept that promotion. Somethimes, I sacrifice my free time for accomplishing hits at work, so it's very important to me to know your opinion base of your experience.

• What programming Language Would you learn to Re-engineer USB Devices? [closed]

  - by user70113

  Currently Work in IT support and am retraining in electrical engineering / electronics, I am also interested in Reverse Engineering which language would be best for Hardware RE, I have seen a few sources say C, C++ and Python? I am not familiar with Linux, but installed Ubuntu to learn with. I am not a programmer. Far from it. But, I can understand enough basic VB,Java and PHP to edit it for simple things. One of my immediate projects would be to learn to reverse engineer USB devices and write my own low level drivers. I know there are porting kits, but I really want to know it from the ground up. Thanks for any advise folks Most Appreciated.

• LaTeX-like display programming environment

  - by Gage

  I used to be a hobbyist programmer, but now I'm also a fairly experienced physicist and find myself programming to solve certain problems quite a lot. In physics, we use variables with superscripts, subscripts, italics, underlines, etc etc. To bridge this gap to the computer we usually use LaTeX. Now, I generally use MATLAB for handling any data and such, and find it very irritating that I can't basically use LaTeX for variable names. Something as simple as sy has to be named either sigma_y or some descriptive name like peak_height_error. I don't necessarily want full on workable LaTeX in my code, but I do want to be able to use greek letters and super/sub-scripts at the very least. Does this exist?

• How can I most efficiently communicate my personal code of ethics, and its implications?

  - by blueberryfields

  There is a lot to the definition of a professional. There are many questions here asking how to identify components of what is essentially a professional programmer - how do you identify or communicate expertise, specialization, high quality work, excellent skills in relation to the profession. I am specifically looking for methods to communicate a specific component, and I quote from wikipedia: A high standard of professional ethics, behavior and work activities while carrying out one's profession (as an employee, self-employed person, career, enterprise, business, company, or partnership/associate/colleague, etc.). The professional owes a higher duty to a client, often a privilege of confidentiality, as well as a duty not to abandon the client just because he or she may not be able to pay or remunerate the professional. Often the professional is required to put the interest of the client ahead of his own interests. How can I most efficiently communicate my professionalism, in the spirit of the quote above, to current and potential clients and employers?

• Learning Python is good?

  - by user15220

  Recently I have seen some videos from MIT on computer programming topics. I found it's really worth watching. Especially the concepts of algorithms and fundamental stuffs. The programs were written and explained in Python. I never had looked into this language before as I learned and doing stuffs with C/C++ programming. But the cleanliness and better readability of syntax attracted me. Of course as a C++ programmer for long time it's the most readable language for me. Also I heard Python library contains solid algorithms and data-structures implementations. Can you share your experience in this language?
