  • How to reinstall many removed packages at once?

    - by Logan
    I used sudo apt-get remove python command and accidently removed a bunch of packages that were required. I logged in via command line and installed ubuntu-desktop again but there are other packages that are missing, and I'm looking for a way to easily reinstall those removed packages. Since there's the log at software-center I wanted to ask what the easiest way might be to roll back changes or extract the removed packages list from the software center... note: I typed sudo apt-get install .... .... ... ... for about two dozen of those removed programs in that list, but when I pressed enter it didn't install any of them because some package names couldn't be found. The programs were removed at the same date.

  • How much to charge Ruby on Rails Website [closed]

    - by eWizardII
    I figured it be appropriate to ask this question on webmasters, over the stackoverflow site seeing as there are similar questions here. I am freelancing for a client in the Boston area, who has the html/css templates for their site made by another web designer. They are basically looking for someone to set up the template, and then make the backend so that a user can purchase music on their site (they are musicians). I am wondering then what would be an appropriate amount to charge them to develop such a system, I am a student, and this would be my 3rd Ruby on Rails project, but probably at least the 20 web design project I have been hired to do and I have other programming knowledge, Python, C, etc. I am thinking of suggesting that they pay 1000usd to set up such a system, but I don't know if this is appropriate. To me it seems justifiable given my experience, and the low end of RoR developers I have seen charging 25usd/hr all the way up to 150usd/hr. Any advice would be appreciated.

  • Reasons for either 32-bit or 64-bit as development machine

    - by vartec
    I'm about to make a new Linux install, which will be primarily used for programming. I've seen benchmarks showing speed improvement of 64-bit version, however, I have hard time of telling how much these benchmarks translate to improvement in every day usage. And of course there are other aspects to consider. Usage I have in mind: mainly programming Python, with occasional C, C++ and Java; IDEs, which are using Java platforms (Eclipse and IntelliJ); on very rare occasions having to compile for 32-bit platform; not planning to have more than 64GB of RAM anytime soon (and I don't mind using PAE kernels); machine in question has 4GB RAM and Athlon II X2; What are pros and cons of choosing either i386 or x86_64 distro?

  • Permissions and MVC

    - by not-rightfold
    I’m in the progress of developing a web application. This web application is mostly a CRUD interface, although some users are only allowed to perform some actions and see only some parts of views. What would be a reasonable way to handle user permissions, given that some parts of views are not available to users? I was thinking of having a function hasPermission(permission) that returns true iff the current user has the given permission, although it would require conditionals around all parts of views that are only visible to some users. For example: {% if has_permission('view_location') %} {{ product.location }} {% endif %} I’m fearing this will become an ugly and unreadable mess, especially since these permissions can get kind of complicated. How is this problem commonly solved in web applications? I’m considering using Haskell with Happstack or Python with Django.

  • Great Programmer Productivity - Accounting for 10,000 fold difference?

    - by TheImpact
    "A great lathe operator commands several times the wage of an average lathe operator, but a great writer of software code is worth 10,000 times the price of an average software writer." - Bill Gates Say there's a "great" software engineer and an "average" software engineer on the same team. How can you account for one engineer being 10,000 times more productive? I can't quite fathom this, given they're both taking on their share of features, bugs and investigations, and consistently deliver with quality. Would my description possibly justify them to be above "average"? "great"? In a corporation like Microsoft, what % of software engineers are "average"? What % "great"?

  • Murali Papana Blogs About Date Effectivity

    - by steve.muench
    Murali Papana from our Human Capital Management (HCM) Fusion Applications team has posted a series of blogs on a lesser-known, but quite powerful feature of ADF called "date effectivity". This is a feature that allows the framework to simplify managing records whose data values are effective for a given period of time. Imagine an employee's job title or salary that changes over time, which as well might be entered today by an HR reprepsentative but go into effect at some time in the future.

  • What are the warning signs of impending doom to watch out for on a project?

    - by ConroyP
    Having worked on a failed project is one of the few things that most programmers have in common, regardless of language used, industry or experience. These projects can be great learning experiences, soul-crushing disasters (or both!), and can occur for a multitude of reasons: upper management change of heart under-skilled / under-resourced team emergence of superior competitor during dev cycle over/under management Once you've worked on a couple of such projects, is it possible to recognise at an early stage exactly when a project is doomed to fail? For me, a big sign is having a hard & fast external deadline combined with feature creep. I've seen projects which were well planned out and proceeding right on schedule go horribly off the rails once the late feature requests started to roll in and get added to the final "deliverable". The proposers of these requests earned the nickname of Columbo, due to rarely leaving the room without asking for "just one more thing". What are the warning signs you look out for that set off the alarm bells of impending doom in your head?

  • Learn About HTML5 and the Future of the Web

    Learn About HTML5 and the Future of the Web San Francisco Java, PHP, and HTML5 user groups hosted an event on May 11th, 2010 on HTML5 with three amazing speakers: Brad Neuberg from Google, Giorgio Sardo from Microsoft, and Peter Lubbers from Kaazing. In this first of the three videos, Brad Neuberg from Google (formerly an HTML5 advocate and currently a Software Engineer on the Google Buzz team) explains why HTML5 matters - to consumers as well as developers! His overview of HTML5 included SVG/Canvas rendering, CSS transforms, app-cache, local databases, web workers, and much more. He also identified the scope and practical implications of the changes that are coming along with HTML5 support in modern browsers. This event was organized by Marakana, Michael Tougeron from Gamespot, and Bruno Terkaly from Microsoft. Microsoft was the host and Marakana, Gamespot, Medallia, TEKsystems, and Guidewire Software sponsored the event. marakana.com From: GoogleDevelopers Views: 177 6 ratings Time: 50:44 More in Science & Technology

  • Update Manager offers 900+ updates under partial upgrade mode

    - by TriforceLZG
    Today I checked for updates and got an error message telling me I must do a partial upgrade. I was shocked to see how many updates there were available. 900+ Updates! By using synaptic I found out that it wanted to remove core packages from my system, such as compiz and python, but also update some as well. I am very confused why package manager would want to do this all of a sudden, and why it wants to destroy my system. I really need an answer, because I now cannot update my system.

  • Is paying programmers to "test" for bugs normal? [on hold]

    - by user106277
    I recently hired a programming team to do a port of my iPad app to the iPhone and Android platforms. I also wanted them to implement a bunch of tips on how to play the app, similar like you would find in Candy Crush or Cut the Rope. They want to charge 12 hours @ $35/hr for the "Testing all of the Tips", telling me that normally it would take them more than 25 hours but that they will 'bear the difference'. I have never heard of this, but maybe it's a new practice? I am used to devs doing their own quality control, and then having a testing/acceptance period... Am I missing something? Thanks for any help and advice you can give!

  • I'm doing hobby programming; what programming methodologies (e.g. XP, Agile...) do you recommend me to read up on?

    - by Anto
    Most of you would probably just call me a kid (I'm 15). I'm doing hobby programming (I started fiddling around with ActionScript 2.0 in Flash 8 when I was 11, now I do mostly C, Python and Java). As I'm 15, I won't get a job for a long period of time (I'm going to spend years in academia before that) and thus this question is not about which programming methodologies you recommend me to read up on for a software engineering job, but instead which methodologies should a hobby programmer read about? What will a hobby developer learn from reading about your recommendation(s)?

  • Is true multithreading really necessary?

    - by Jonathan Graef
    So yeah, I'm creating a programming language. And the language allows multiple threads. But, all threads are synchronized with a global interpreter lock, which means only one thread is allowed to execute at a time. The only way to get the threads to switch off is to explicitly tell the current thread to wait, which allows another thread to execute. Parallel processing is of course possible by spawning multiple processes, but the variables and objects in one process cannot be accessed from another. However the language does have a fairly efficient IPC interface for communicating between processes. My question is: Would there ever be a reason to have multiple, unsynchronized threads within a single process (thus circumventing the GIL)? Why not just put thread.wait() statements in key positions in the program logic (presuming thread.wait() isn't a CPU hog, of course)? I understand that certain other languages that use a GIL have processor scheduling issues (cough Python), but they have all been resolved.

  • Can static and dynamically typed languages be seen as different tools for different types of jobs?

    - by Erik Reppen
    Yes, similar questions have been asked but always with the aim of finding out 'which one is better.' I'm asking because I came up as a dev primarily in JavaScript and don't really have any extensive experience writing in statically typed languages. In spite of this I definitely see value in learning C for handling demanding operations at lower levels of code (which I assume has a lot to do with static vs dynamic at the compiler level), but what I'm trying to wrap my head around is whether there are specific project contexts (maybe certain types of dynamic data-intensive operations?) involving things other than performance where it makes a lot more sense to go with Java or C# vs. something like Python.

  • Languages/Methods to Learn for Scientific Computing?:

    - by Zéychin
    I'm a second-semester Junior working towards a Computer Science degree with a Scientific Computing concentration and a Mathematics degree with a concentration on Applied Discrete Mathematics. So, number crunching and such rather than a bunch of regular expressions, interface design, and networking. I've found that I'm not learning new relevant languages from my coursework and am interested in what the community would recommend me to learn. I know as far as programming methods go, I need to learn more about parallelizing programs, but if there's anything else you can recommend, I would appreciate it. Here's a list of the languages with which I am very experienced (web technologies omitted as they barely apply here). Any recommendations for additional languages I should learn would be very much appreciated!: Java C C++ Fortran77/90/95 Haskell Python MATLAB

  • How can a student programmer improve his teamwork skill?

    - by xiao
    I am a student right now. Recently, I am working in a project as a leader with three other students. Due to the lack of experience, our project is progressing slowly and our members are frustrated. They do not feel sense of accomplishment in the project. I am pressured and frustrated, too. But as a team leader, I think I need to push them. But I do not know how to do. Do I help them solve coding problem or just encouragement? But if I pay too much attention on it, it would slow down my own progress. It is a not technical question, but it is very common in software development. I hope veteran programmers would give me some suggestions. Thanks!

  • Naming conventions used for variables and functions in C

    - by Zel
    While coding a large project in C I came upon a problem. If I keep on writing more code then there will be a time when it will be difficult for me to organize the code. I mean that the naming for functions and variables for different parts of the program may seem to be mixed up. So I was thinking whether there are useful naming conventions that I can use for C variables and functions? Most languages suggest a naming convention. But for C the only thing I have read so far is the names should be descriptive for code readability. EDIT: Examples of some examples of suggested naming conventions: Python's PEP 8 Java Tutorial I read some more naming conventions for java somewhere but couldn't remember where.

  • career advice for PhD scientist seeking to program?

    - by C SD
    I'm largely a self-taught programmer. In fact, I first started programming about half way through biophysics grad school, and even though I think I've done some pretty nice work, I've never worked as part of a 'serious' development team that had more than one or two other developers (and I wouldn't hesitate to call them equally inexperienced in software development as a profession). After finishing my PhD I applied to Google, on a lark, since I had some confidence in my abilities, if not necessarily my experience, and I was hoping to maybe slip in and absorb all the experience and talent I'd be surrounded with and become productive enough, quickly enough, that they wouldn't immediately regret their decision. I was excited to actually get invited to interview up at Mountain View (this was ~ mid 2008). Overall, my memory of the interview was very positive, but after close to a three month wait (is that normal?) they ended up turning me down. I wasn't too surprised or disappointed (aside from the uncomfortably long wait) given my unusual background and admitted lack of experience. I decided to continue as a postdoc, but focus on improving my skills rather than doing research. I've done about three years of that, and my honest assessment is that I've learned a ton more, but I really need more of a peer group to maintain or accelerate my growth. Google invited me to interview again about eight months ago, and the interview process went even better than the first time around (I thought), though they again declined to give me an offer. I have to admit this second rejection was much more discouraging. They had insisted I interview even after I mentioned to them that a move on my part was unlikely given that I had bought a house, gotten married, etc. since the first interview. I guess I was hoping they'd at least give me an offer that I could parlay into a more conventional, but still interesting, programming position close to home. So here I am, going on my third year out of grad school, a glorified postdoc and I'm starting to get pretty discouraged. Even though I could technically get 'back-on-track' for a career in science, I have been focusing the vast majority of this time on gaining programming experience rather than on research and publications. The problem is, whenever I look, most job listings have requirements that seem impossibly grandiose and I hesitate to apply. That, or the job/project seems incredibly dull. Ironically, applying to Google struck me as less intimidating. I suspect that either most people are just a lot less realistic than I am when it comes to assessing how long it will take for them to get up to speed, or they don't care; my fear is that I'm just woefully unqualified for any interesting, well paying work. IE: I'm confident I could switch fully back into C++ mode with a couple weeks work (I mostly use C,Python,C# daily) but I don't list myself as being 'proficient' in C++ on my CV, or applying for jobs that 'require' such knowledge. The few applications for which I did feel I was a legitimately good match have not elicited a response. I suspect the following things are potential problems with my application/CV and I would like feedback on: I don't have a CS degree. My BS was in biochemistry and molecular biology, my PhD in biophysics. I took a undergrad and grad level CS course at UCSD and completely killed them, but I don't know how to translate that to my CV effectively. I have a PhD, but it's not in CS... I've been debating if I should remove it from my CV, and wether or not it would then be misleading to list at least some of those years as some kind of 'programming' job (in many respects it was). I think there are sometimes strong stigmas associated with 'self-taught' programmers. I am certainly one of those. I even recognize that some of those stigmas hold a hint of truth, but I really do want to be an asset to a team. How do I communicate that even though I have been largely self-directing for ~8 years I can still take marching orders when needed? Do I just say so outright? Should I just become a lot less scrupulous about the whole process? anecdote: I have a friend who applied for positions where he completely fudged his qualifications to get past the first culling. He was much more honest and forthcoming about his actual qualifications when contacted and he still managed to get invited to a couple of interviews and even got some offers. His balls are larger than mine though.

    - by user1758043
    I am working as a Python developer and I work with django. I also do some web scraping and building spiders and bots. Now from there I want to make my move to Business Intelligence. I just want to know how I can move into that field. Because as companies are not going to hire me in that field directly, I just want to know how can I make the transistion. I was thinking of first working as Database developer in SQL and then I can see further. But I want advice from you guys so that I can start learning that stuff so that I can change jobs keeping that in mind. Here in my area there are plenty of jobs in all areas but I need to know how to transition and what things I should learn before making that transition. Here jobs are plenty so if I know my stuff, getting a job is a piece of cake because they don't have any people. Same jobs keep getting advertised for months and months.
