  • Need Advice on building the database. all in one table or split?

    - by Ibrahim Azhar Armar
    hello, i am developing an application for a real-estate company. the problem i am facing is about implementing the database. however i am just confused on which way to adopt i would appreciate if you could help me out in reasoning the database implementation. here is my situation. a) i have to store the property details in the database. b) the properties have approximately 4-5 categories to which it will belong for ex : resedential, commnercial, industrial etc. c) now the categories have sub-categories. for example. a residential category will have sub category such as. Apartment / Independent House / Villa / Farm House/ Studio Apartment etc. and hence same way commercial and industrial or agricultural will too have sub-categories. d) each sub-categories will have to store the different values. like a resident will have features like Bedrooms/ kitchens / Hall / bathroom etc. the features depends on the sub categories. for an example on how i would want to implement my application you can have a look at this site. http://www.magicbricks.com/bricks/postProperty.html i could possibly think of the solution like this. a) create four to five tables depending upon the categories which will be existing(the problem is categories might increase in the future). b) create different tables for all the features, location, price, description and merge the common property table into one. for example all the property will have the common entity such as location, total area, etc. what would you advice for me given the current situation. thank you

  • Best practices for custom http user-agent strings?

    - by Noufal Ibrahim
    I'm developing an application that communicates with an internal web service using HTTP. Are there any "best practices" for custom user-agent strings so that I can put a nice one in my app? It's a Python library and the lower transport is Python's own httplib. Should the user-agent string say that or something else?

  • Private VCS hosts for school projects?

    - by Ibrahim
    I want to use version control for a partner project for school, but these days it seems like there are no private, free VCS hosts that I could use. I would prefer to use git if possible, but I wouldn't mind SVN. Alternatively, if there aren't any, shouldn't there be some way for me to use git without a central repository? I don't know enough about git, but I assume that is the point of a DVCS, no? I've considered scp'ing a clone of the repository to my school unix account and then giving my partner access to that, but it seems like it would be a bit of a pain. What are your thoughts/suggestions? Edit: I do know of one site called xp-dev, but I'm not sure how much I trust it. But I could use that and use git-svn on my side, since my partner has actually only ever used svn. But still wondering if there are any alternatives.

  • Gitosis Directories of repositories per user?

    - by Ibrahim
    I was just wondering, is there a way to set up gitosis so that a user would have their own directory to which they could push any number of repositories that they want, and essentially have admin privs on that directory? This might be kind of confusing, but essentially I want something like how on github all your repositories are accessible at urls like [email protected]:username/repofoo.git . I realize that setting up each repo is a somewhat manual process that could be automated via a script, like I assume github does, but is there any way to do something like this overall, minus the automated repository creation? I guess I'm open to trying to set up gitorious or something if it allows this, but gitosis works pretty well for me right now and it was dead easy to set up, and I've heard that gitorious is not so easy. Thanks! I've heard of other forks/clones of gitosis that have per branch permissions like gitolite, but I'm not sure whether I want to use one of those unless they have other compelling features and are as well documented and easy to use as gitosis.

  • Using git-svn with slightly strange svn layout

    - by Ibrahim
    Hi guys, I'm doing an internship and they are using SVN (although there has been some discussion of moving to hg or git but that's not in the immediate future). I like git so I would like to use git-svn to interact with the svn repository and be able to do local commits and branches and stuff like that (rebasing before committing to svn of course). However, there is one slight wrinkle, the svn repository layout is a little weird. It basically looks like this /FOO +-branches +-tags +-trunk +-FOO +-myproject Basically, my project has been stuck into a subdirectory of trunk, and there is another project that is also a subdirectory of the trunk. If I use git-svn and only clone the directory for my project instead of the root, will it get confused or cause any problems? I just wonder because the commit numbers are incremented for the entire repository and not just my project, so would commits be off or anything like that? I probably wouldn't push any branches or tags to SVN because I'd prefer to just do those locally in git and I don't know how git-svn deals with branches and tags anyway, and no one else uses them so I find little point in doing so. Thanks for the help!

  • Making only one task run at a time in celerybeat

    - by Noufal Ibrahim
    I have a task which I execute once a minute using celerybeat. It works fine. Sometimes though, the task takes a few seconds more than a minute to run because of which two instances of the task run. This leads to some race conditions that mess things up. I can (and probably should) fix my task to work properly but I wanted to know if celery has any builtin ways to ensure this. My cursory Google searches and RTFMs yielded no results.

  • TDD - beginner problems and stumbling blocks

    - by Noufal Ibrahim
    While I've written unit tests for most of the code I've done, I only recently got my hands on a copy of TDD by example by Kent Beck. I have always regretted certain design decisions I made since they prevented the application from being 'testable'. I read through the book and while some of it looks alien, I felt that I could manage it and decided to try it out on my current project which is basically a client/server system where the two pieces communicate via. USB. One on the gadget and the other on the host. The application is in Python. I started off and very soon got entangled in a mess of rewrites and tiny tests which I later figured didn't really test anything. I threw away most of them and and now have a working application for which the tests have all coagulated into just 2. Based on my experiences, I have a few questions which I'd like to ask. I gained some information from http://stackoverflow.com/questions/1146218/new-to-tdd-are-there-sample-applications-with-tests-to-show-how-to-do-tdd but have some specific questions which I'd like answers to/discussion on. Kent Beck uses a list which he adds to and strikes out from to guide the development process. How do you make such a list? I initially had a few items like "server should start up", "server should abort if channel is not available" etc. but they got mixed and finally now, it's just something like "client should be able to connect to server" (which subsumed server startup etc.). How do you handle rewrites? I initially selected a half duplex system based on named pipes so that I could develop the application logic on my own machine and then later add the USB communication part. It them moved to become a socket based thing and then moved from using raw sockets to using the Python SocketServer module. Each time things changed, I found that I had to rewrite considerable parts of the tests which was annoying. I'd figured that the tests would be a somewhat invariable guide during my development. They just felt like more code to handle. I needed a client and a server to communicate through the channel to test either side. I could mock one of the sides to test the other but then the whole channel wouldn't be tested and I worry that I'd miss that. This detracted from the whole red/green/refactor rhythm. Is this just lack of experience or am I doing something wrong? The "Fake it till you make it" left me with a lot of messy code that I later spent a lot of time to refactor and clean up. Is this the way things work? At the end of the session, I now have my client and server running with around 3 or 4 unit tests. It took me around a week to do it. I think I could have done it in a day if I were using the unit tests after code way. I fail to see the gain. I'm looking for comments and advice from people who have implemented large non trivial projects completely (or almost completely) using this methodology. It makes sense to me to follow the way after I have something already running and want to add a new feature but doing it from scratch seems to tiresome and not worth the effort. P.S. : Please let me know if this should be community wiki and I'll mark it like that. Update 0 : All the answers were equally helpful. I picked the one I did because it resonated with my experiences the most. Update 1: Practice Practice Practice!

    - by Ibrahim Azhar Armar
    hi, i am building a real estate application where in it will store the properties and search it. the property will have different categories like (residential, commercial, industrial or agricultural). based upon the category i want to serailize each and every property listing . for example the property with id 1 belongs to resedential will have the serial code rs_SOMERANDOMUNIQUENUMBER. and for commercial it can be cm_SOMERANDOMUNIQUENUMBER and so on. for this my database table looks like this. CREATE TABLE IF NOT EXISTS `propSerials` ( `id` bigint(20) NOT NULL auto_increment, `serial` varchar(50) NOT NULL, `property_id` int(10) UNIQUE NOT NULL, PRIMARY KEY  (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8; what would be the best possible format to store the serial with the prefix according to category? thank you

  • HBase as a multimap

    - by Ibrahim
    Hi guys, I'm doing some large scale text processing work and I'm trying to get started with Hadoop and HBase. One of the things I need to do is build a multimap of some stuff, which I later use to look up things and get all items with a certain key (in a M/R job). Would it be OK to use HBase and insert many rows with the same key and rely on versions/timestamps to achieve a multimap-like setup or is this a bad idea? The multimap is built up in the reduce phase of a Mapreduce task by the way, or at least in the way I've formulated it on paper. Thanks! If more information is needed, I'd be happy to provide it. Not sure whether this question is clear.

  • Lesi, from Graduate Trainee to Territory Manager

    - by Maria Sandu
    Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 It’s the final year, University is now coming to an end. A new chapter now awaits my arrival. This part of my life is called “Looking for a Job”. With no form of experience whatsoever, getting a job at a well renowned IT company is something that every IT student dreams about. CV: v, Application form: v, interviews: v. Acceptance Call, “Lesi I’m pleased to inform you that you have been accepted to be part of the Oracle Graduate Program for 2012”. Life would never again be the same. Being Part of the Graduate Program Going into the Graduate program, I felt like a baby seeing candy for the first time. The Program gave me the platform to not only break in to the workplace but also to help launch my career. Over the next 3 months, I went through various trainings / workshops / events / coaching / mentorship sessions. Like a construction worker building a solid foundation for a beautifully designed architecture, a clear path to build my career was set. With training out the way, it was now time to start working closely with my team. For the rest of the year, it was all about selling. Sales, Pipeline, Forecasting and numbers soon became the common words in my career. As the saying goes, “once a sales man, always a sales man”. There was no turning back now, a career in sales was the new hustle in my life. I worked closely with my mentor & coach (Ibrahim) who was heading up Zambia and Malawi. This was to be one of my best moments in the program as I started engaging with customers and getting some hands on experience in the field. By the end of the program all the experience, hard work, training and resources came in handy as I was now ready and fully groomed to be a sales rep. Life after the Graduate Program I’m proud to say that now I’m a Territory Manager, heading up Malawi, selling Technology, Middleware & Applications across all industries. I’m part of the Transition Cluster Team, a powerful team headed by the seasoned Senior Director. As a Territory Manager my role is to push for coverage, to penetrate the market by selling Oracle from end- to- end to all accounts in Malawi. I now spend my days living out of a suitcase, moving from hotel to hotel, chasing after business in all areas of Malawi. It’s the life of a Sales Man and I’m enjoying every minute of it. I’m truly fortunate and grateful to have been part of such a wonderful graduate program. I owe my Sales career to the graduate program, and I truly hope that the program will continue to develop and to groom new talent amongst the youth of this world.
