  • git changing head not reflected on co-dev's branch

    - by stevekrzysiak
    Basically, we undid history. I know this is bad, and I am already committed to avoiding this at all costs in the future, but what is done is done. Anyway, I issued a git push origin <1_week_old_sha:master to undo some bad commits. I then deleted a buggered branch called release(which had also received some bad commits) from remote and then branched a new release off master. I pushed this to remote. So basically, remote master & release are clones and just how I want them. The issue is if I clone the repo anew(or work in my current repo) everything looks great....but when my co-devs delete their release branch and create a new one based off the new remote release I created, they still see all the old junk I tried to remove. I feel this has to do with some local .git files mistaking the new branch release for the old release. Any thoughts? Thanks.

  • May I give a single class multiple responsibilities if only one will ever be reusable?

    - by lnluis
    To the extent that I understand the Single Responsibility Principle, a SINGLE class must only have one responsibility. We use this so that we can reuse other functionalities in other classes and not affect the whole class. My question is: what if the entity has only one purpose that really interacts with the system, and that purpose won't change? Do you have to separate the implementations of your methods into another class and just instantiate those from your entity class? Or to put it another way... Is it ok to break the SRP if you know those functions will not be reusable in the future? Or is it better to assume that we do not know if the functionalities of these methods will be reusable or not, and so just abstract them to other classes?

  • Should I Learn C/C++ Even If I Just Want To Do Web Programming?

    - by Daniel
    My goal is to be able to create online apps and dynamic, database driven websites. For instance, if in the future I get the idea for the next Digg or Facebook, I want to be able to code it myself. To arrive there I think I have basically two paths: Path 1 Start at a basic level, learning C, then C++ for OOP, then algorithms and data structures, with the goal of getting a solid grasp of computer programming. Only then move to PHP/MySQL/HTTP and start working on practical programming projects. Path 2 Start directly with PHP/MySQL/HTTP and getting my hands dirty with practical projects right away. What would you guys recommend?

  • HTML5 Audio: Which formats? Ditch Ogg Vorbis in favor of Ogg Opus? Is MP3 still needed?

    - by phoibos
    I'm currently working on a website which has to stream audio files. Since bandwidth is always an issue, the file size should be as small as possible. I wonder what audio formats I should provide. MP3 - Most common format but low quality, I don't know if it's even required, since AAC is well supported by the browsers incapable of playing free codecs MP4 AAC - Nice quality / small filesize, supported by Safari / Mobile Devices / IE9 / Flash / Chrome A free codec - well, until recently, there only was Ogg Vorbis, but Ogg Opus is standardized now and it's really good! Questions: Is it time yet to use Opus instead if Vorbis? Firefox supports Opus since version 15, and Opera has support on its roadmap - I guess Chrome will follow in the future too. Do I still have to provide an MP3 file?

  • Will the Global Demand for Water Outstrip the Supply by 2030?

    - by Evelyn Neumayr
    A recent study conducted by the Economist Intelligence Unit and sponsored by Oracle Utilities, titled “Water for All?”,considers the preparedness of utilities to supply water to the current global population of over 7 billion people, with a further 1 billion expected by 2030. It compares strategies used by utilities in 10 major countries to address this challenge. This study’s findings show that wide-ranging water management efforts and large-scale investments must be made if utilities are to meet near-certain water stress—demand outstripping supply—by 2030. The report is based on an online survey of 244 executives of water utilities in these countries, supplemented by in-depth interviews with 20 water utility executives and independent experts. The research concludes that utilities worldwide expect to meet future demand, despite increased supply pressure on supplies, due to improvements in water productivity that the wide range of measures utilities and governments will take to ensure that water is used more efficiently.

    - by linjunhalida
    hello, I'm a python & Qt programmer, and my daily job is create small PC GUI programs ship with hardware devices. the problem is, My job is simple, read/write data to device by using serial port(pyserial), display and edit data(PyQt + PyQwt), that's all. although I'm a linux user, my program is running under windows XP, but thanks to PyQt, I can still develop under linux. And I'm always afraid of being replaced by the people cheaper and younger than me in the future. (I'm 26 now.. not too much time for playing..) So I need improve myself, and make me more competitive in the global market, and I like programming, and want coding till the end of my life. any roadmap suggestion?

  • Mac OS X: Best way to do runtime check for retina display?

    - by Todd Ditchendorf
    Given a Cocoa application which runs on Mac OS X 10.7 and later: What is the best way to check, at runtime, if your app is currently running on a Mac with at least one retina display attached? If checking for this sort of thing is just really wrong-headed, I fully welcome a well-reasoned explanation of why. But I'd still like to know :). It seems likely you could just do a check specifically for the new Mac Book Pro "Retina" hardware (the only Mac at this time which currently has a retina display), but ideally, I'd really prefer a more general/generic/future-proof way to check than this. Ideally, I'd like to know how to detect the retina display, not the specific Mac model which currently happens to ship with a retina display.

  • Implementing Tagging using Core Data on the iPhone

    - by Jonathan Penn
    I have an application that uses CoreData and I'm trying to figure out the best way to implement tagging and filtering by tag. For my purposes, if I was doing this in raw SQLite I would only need three tables, tags, item_tags and of course my items table. Then filtering would be as simple as joining between the three tables where only items are related to the given tags. Quite straightforward. But, is there a way to do this in CoreData and utilizing NSFetchedResultsController? It doesn't seem that NSPredicate give you the ability to filter through joins. NSPredicate's aren't full SQL anyway so I'm probably barking up the wrong tree there. I'm trying to avoid reimplementing my app using SQLite without CoreData since I'm enjoying the performance CoreData gives me in other areas. Yes, I did consider (and built a test implementation) diving into the raw SQLite that CoreData generates, but that's not future proof and I want to avoid that, too. Has anyone else tried to tackle tagging/filtering with CoreData in a UITableView with NSFetchedResultsController

  • How can I undo this key mapping?

    - by user273872
    First of all sorry my punctuation will be bad. its hard to type when keys are not doing what you expect. Eg it keeps scaring the **** out of me by taking a screen shot when I push the up arrow lolol So anyways, I broke a key on my keyboard and used xkeycaps to remap it to an unused key which worked. But then I realized it screwed up other keys... I think this is the program I used http://www.jwz.org/xkeycaps/man.html And then after doing the modifications I found out how to save them from the second answer in this question How to Map my enter key to a different key down where it says this "When you are happy with your current keymap and want to use it in future X-sessions, run the following command to save it: xmodmap -pke ~/.Xmodmap"

  • Should a new programmer nowadays start with C/C++ or OOP language? [closed]

    - by deviDave
    I've been a programmer for 15+ years. In my time, we all started with C or C++ and then moved to C# or Java. At that time it was a usual practice. Now, my brother wants to follow my steps and I am not sure what advice to give him. So, I am asking the community for an opinion. Should nowadays new programmer with zero programming knowledge start with functional languages (C, C++, etc.) or he should start directly with OOP languages (Java, C#, etc.)? The reply should be considered in the context of my brother's future assignments. He will mainly work on Java mobile applications as well as ASP.NET web apps. He will have to touch with desktop apps, low level programming, drivers, etc. This is the reason I am not sure if he should ever need to learn functional languages.

  • Retrieve data from an ASP.Net application using ADO.Net 2.0 connected model

    - by nikolaosk
    I have been teaching Entity Framework,LINQ to SQL,LINQ to objects,LINQ to XML for some time now. I am huge fan of LINQ to Entities and I am using Entity Framework as my main data access technology. Entity framework is in the second version right now and I can accomplish most of the things I need. I am sure the guys in the ADO.Net team will implement many more features in the future. I am a strong believer that you cannot really understand the benefits of LINQ to SQL or LINQ to Entities unless you...(read more)

  • How to login after modifying ~/.profile wrongly

    - by Jasper Loy
    I did something very silly a few weeks ago. I wanted to add a path so that the OS could find some manually installed executable. Instead of typing 'PATH=xxx:$PATH;export PATH' at the end of the ~/.profile file where xxx is the directory in which the executable lies, I accidentally typed 'PATH=xxx;export PATH'. After I logged out I was unable to login anymore as I probably messed up the whole PATH variable and reinstalled the whole thing. My question is: is there a way of rectifying the situation if I happen to add the path wrongly (hopefully not!) in future?

  • Extended Events demos on Microsoft Virtual Academy

    - by extended_events
    I had an opportunity recently to contribute a presentation to the Microsoft Virtual Academy as part of the Mission Critical Confidence using SQL Server 2012 course offering. The MVA offers you a myriad of free training opportunities, so I encourage anyone who is interested in expanding your knowledge to take advantage of this offering. For those of you who don’t want to invest the time to go through the whole course, you can access my presentation here. I cover the following topics: Integration of Extended Events into AlwaysOn troubleshooting. Troubleshooting Login failures using client/server correlation. Troubleshooting query performance issues using client/server correlation. I’m not sure how long content is made available on MVA, I got the impression that it would be removed as some point in the future, but should be there for at lease several months. - Mike

  • Contact Form Domain Blacklists (using java, html or php)

    - by Tim
    I'm using HTML contact forms on a business site to post lead information to Salesforce. We're using auto-responders to deliver key information to people who complete a form asking for additional information. The goal is to reject forms that are submitted by competitors. It doesn't need to be bullet proof; the main idea is to reject and form that has an email address associated with a competitor's domain. Can anyone help? Thanks!

  • Firefox adopte le H.264 après avoir longtemps bataillé contre ce codec propriétaires : pragmatisme ou renoncement ?

    Firefox adopte le H.264 après avoir longtemps bataillé contre ce codec propriétaires : pragmatisme ou renoncement ? Le codec H.264 a longtemps fait débat divisant les navigateurs en deux clans. Mozilla s'était rangé dans le camp contre ce codec, refusant catégoriquement d'obtenir une licence propriétaire pour son Firefox. La fondation militait depuis le début pour un web ouvert à 100%. Mais voila que sur le groupe de discussions de ses développeurs, Andreas Gal, Directeur de la recherche de Mozilla, annonce un revirement de situation total. Du moins en ce qui concerne la future plateforme mobile de la fondation à but non lucratif. [IMG]http://ftp-developpez....

  • Time it would take me to learn c++ given my speed? [closed]

    - by ashwin
    I am a student in second year of engineering and my life is hard, nowadays. To make my future secure and at least get good jobs, I have started learning C++; I have learned J2SE, ASP.NET (little, basic C#), PHP (little), HTML, CSS, AJAX, Javascript, SQL, a little android development (I have built a benchmark app) in 4 months and have received 1 gold medal in CSS and 1 each in HTML, CSS, Java. I am able to make things in C#, Java and all other, so I can apply all this knowledge. I was able to do all this, because I loved learning and I hate to ask this question. How much time would it take me to learn C++, good-enough to get good jobs at Google, Microsoft? I am currently learning data structures, so that's excluded.

  • Should I force users to update an application?

    - by Brian Green
    I'm writing an application for a medium sized company that will be used by about 90% of our employees and our clients. In planning for the future we decided to add functionality that will verify that the version of the program that is running is a version that we still support. Currently the application will forcequit if the version is not among our supported versions. Here is my concern. Hypothetically, in version 2.0.0.1 method "A" crashes and burns in glorious fashion and method "B" works just fine. We release 2.0.0.2 to fix method A and deprecate version 0.1. Now if someone is running 0.1 to use method B they will be forced to update to fix something that isn't an issue for them right now. My question is, will the time saved not troubleshooting old, unsupported versions outweigh the cost in usability?

  • Is Java "dead in the water" as a consequence of Oracle buying Sun and subsequently suing Google

    - by NimChimpsky
    Google has led many useful Java features (guava, gson); now that Oracle has purchased Sun will it effect its future enhancements and utilization as a development language. What exactly, or even approximately, are the legal ramifications? I thought Java was open source and would therefore remain unaffected ... ? Should Google just buy Oracle to get rid of the whole mess, that would be cool wouldn't it ? Do you think this is the beginning of the end for Java as a widely used language ? Its continued success as an open source/free technology is now doubtful?

  • How do I make the correct career decision in regards to product manager/QA vs programmer?

    - by Adel
    I'm curious about how to approach the issue of whether I should focus on programming or on QA/testing/product management. I know that the latter seems like a broad category( if so, think of it as "general IT support" for now). At the moment I'm stronger in QA/prod. mgt ; however I'd like to switch more to programming, and I see I may have this opportunity. Wouldn't it be easier to switch to QA/prod. mgt in the future, if I go into programming now; rather than trying the reverse-order(i.e. if I decided later to go into coding.. say around mid-30s then it'd likely be harder). Just looking for any advice or tips about how to see more clearly. Part of me is scared I can't handle the programming side, but part of me says since there's demand and I'm interested that it's still worth a shot.
