  • Dell wireless not working after upgrade

    - by Omer Saeed
    So, the short version of my sad story is that I tried upgrade Ubuntu to 12.04 and wireless driver has stopped working. I have tried all the solutions but nothing seem to be working. When I try to install my wireless from "Additional Drivers" Its says: Sorry, installation of this driver failed. Please have a look at the log file for details: /var/log/jockey.log The lspci command gives me the following info about wireless: 0c:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01) I have tried removing bcm drivers and reinstalling, but nothing seems to be working. rfkill is good too.

  • Should I modify an entity with many parameters or with the entity itself?

    - by Saeed Neamati
    We have a SOA-based system. The service methods are like: UpdateEntity(Entity entity) For small entities, it's all fine. However, when entities get bigger and bigger, to update one property we should follow this pattern in UI: Get parameters from UI (user) Create an instance of the Entity, using those parameters Get the entity from service Write code to fill the unchanged properties Give the result entity to the service Another option that I've experienced in previous experiences is to create semantic update methods for each update scenario. In other words instead of having one global all-encompasing update method, we had many ad-hoc parametric methods. For example, for the User entity, instead of having UpdateUser (User user) method, we had these methods: ChangeUserPassword(int userId, string newPassword) AddEmailToUserAccount(int userId, string email) ChangeProfilePicture(int userId, Image image) ... Now, I don't know which method is truly better, and for each approach, we encounter problems. I mean, I'm going to design the infrastructure for a new system, and I don't have enough reasons to pick any of these approaches. I couldn't find good resources on the Internet, because of the lack of keywords I could provide. What approach is better? What pitfalls each has? What benefits can we get from each one?

  • SEO - different data with same title and keywords

    - by Junaid Saeed
    here is my scenario i have a website where i redirect my users basing upon the device they were using, lets say a user is visiting from an iPad, i take him directly to the page of iPad wallpapers, the user selects iPad version & i take the user to the gallery of wallpapers where the user can select & download any wallpaper. Every wallpaper is the required resolution, i have my reasons for doing this, now the thing is there are diff. resolution. versions of an image appearing one 5 diff. sections of my website, each having their own view page Now there is only one record in db.table for the image, and basing on the my consistent naming convention of the images, i pick the required image. this means when 5 different pages are generated in 5 categorized sections of the website, due to a shared DB record, the keywords, the titles and every single detail of the 5 pages is same besides the resolution of the image, and the section specific details that the page has and yeah the pages also have different paths like wallpapers.com\ipad-1\cars\Ferrari-dino.html wallpapers.com\ipad-2\cars\Ferrari-dino.html wallpapers.com\ipad-3\cars\Ferrari-dino.html wallpapers.com\ipad-4\cars\Ferrari-dino.html wallpapers.com\ipad-5\cars\Ferrari-dino.html now this is my scenario, How do Search Engines see it and how do they rank it? Is it a Good or Normal or Bad SEO practice? If bad how dangerous it is for my sites SEO? i need your comments on my scenario.

  • Should we encourage coding styles in favor of developer's autonomy, or discourage it in favor of consistency?

    - by Saeed Neamati
    A developer writes if/else blocks with one-line code statements like: if (condition) // Do this one-line code else // Do this one-line code Another uses curly braces for all of them: if (condition) { // Do this one-line code } else { // Do this one-line code } A developer first instantiates an object, then uses it: HelperClass helper = new HelperClass(); helper.DoSomething(); Another developer instantiates and uses the object in one line: new HelperClass().DoSomething(); A developer is more easy with arrays, and for loops: string[] ordinals = new string[] {'First', 'Second', 'Third'}; for (i = 0; i < ordinals.Length; i++) { // Do something } Another writes: List<string> ordinals = new List<string>() {'First', 'Second', 'Third'}; foreach (string ordinal in ordinals) { // Do something } I'm sure that you know what I'm talking about. I call it coding style (cause I don't know what it's called). But whatever we call it, is it good or bad? Does encouraging it have an effect of higher productivity of developers? Should we ask developers to try to write code the way we tell them, so to make the whole system become style-consistent?

  • Any algorithm to dedicate a set of known resources to a set of known requirements (scheduling)

    - by Saeed Neamati
    I'm developing an application to help school principals in dedicating teachers to classes and courses over the hours of a week (scheduling). The scenario is roughly something like this: User enters the list of teachers and their free times into the system User enters the list of courses for this semester User enters the list of available classes into the system Well, up to here, there is no big deal. Just simple CRUD operations and nothing extraordinary. However, now what makes this system useful is that the application should automatically and based on an algorithm create the semester scheduling. I think you've got the main idea here. For example application should suggest that teacher A should go to class 1 for mathematics, and at the same time teacher B should go to class 2 for physics. This way all of the classes would be dedicated to lessons and teacher times won't overlap each other. Piece a cake for school principal. However, I can't find a good algorithm for this resource dedication. I mean it seems hard to me. Searching Google resulted in articles from different websites, but they are of no help and use to me. For example: http://en.wikipedia.org/wiki/Resource_allocation or http://en.wikipedia.org/wiki/Scheduling_(production_processes) Is there any algorithm out there, or any application or engine which can help me here? Does this requirements have a known name, like for example time scheduling engine? Any help would be appreciated.

  • Why it is called "hash table", or "hash function"? Hash doesn't make any sense to me here

    - by Saeed Neamati
    It's now about 4 years of development that I'm using, hearing, talking about, and implementing hash tables and hash functions. But I really never understand why it's called hash? I remember the first days I started programming, this term was kind'of cumbersome terminology to me. I never figured out what is it, based on its name. I just experimentally understood what it does and why and when should we use it. However, I still sometimes try to figure out why it's called hash. I have no problem with table or function and to be honest, they are pretty deductive, rational terms. However, I think better words could be used instead of hash, like key, or uniqueness. Don't key table or uniqueness table. According to my dictionary, hash means: Fried dish of potato and meats (highly irrelevant) # symbol (AKA number sign, pound sign, etc.) (still irrelevant, maybe just a mis-nomenclature) Apply algorithm to character string (still has nothing to do with uniqueness, which is the most important feature of a hash table) Cut food Another term for hashish Does anyone know why it's called hash?

  • Interface (contract), Generics (universality), and extension methods (ease of use). Is it a right design?

    - by Saeed Neamati
    I'm trying to design a simple conversion framework based on these requirements: All developers should follow a predefined set of rules to convert from the source entity to the target entity Some overall policies should be able to be applied in a central place, without interference with developers' code Both the creation of converters and usage of converter classes should be easy To solve these problems in C# language, A thought came to my mind. I'm writing it here, though it doesn't compile at all. But let's assume that C# compiles this code: I'll create a generic interface called IConverter public interface IConverter<TSource, TTarget> where TSource : class, new() where TTarget : class, new() { TTarget Convert(TSource source); List<TTarget> Convert(List<TSource> sourceItems); } Developers would implement this interface to create converters. For example: public class PhoneToCommunicationChannelConverter : IConverter<Phone, CommunicationChannle> { public CommunicationChannel Convert(Phone phone) { // conversion logic } public List<CommunicationChannel> Convert(List<Phone> phones) { // conversion logic } } And to make the usage of this conversion class easier, imagine that we add static and this keywords to methods to turn them into Extension Methods, and use them this way: List<Phone> phones = GetPhones(); List<CommunicationChannel> channels = phones.Convert(); However, this doesn't even compile. With those requirements, I can think of some other designs, but they each lack an aspect. Either the implementation would become more difficult or chaotic and out of control, or the usage would become truly hard. Is this design right at all? What alternatives I might have to achieve those requirements?

  • How do Python and PHP compare for ecommerce?

    - by Ibn Saeed
    If I were to start an ecommerce store, which language would you suggest I start with? Python or PHP? And would it be wise to use Python for an ecommerce site in favor of PHP? PHP has lots of shopping carts, both open source and commercial. Is Python the future of Web Development ? Edit: I would like to clear out that i am not asking for Shopping carts solutions and links to them.

  • Java Code for calculating Leap Year, is this code correct ?

    - by Ibn Saeed
    Hello I am following "The Art and Science of Java" book and it shows how to calculate a leap year. The book uses ACM Java Task Force's library. Here is the code the books uses: import acm.program.*; public class LeapYear extends ConsoleProgram { public void run() { println("This program calculates leap year."); int year = readInt("Enter the year: "); boolean isLeapYear = ((year % 4 == 0) && (year % 100 != 0) || (year % 400 == 0)); if (isLeapYear) { println(year + " is a leap year."); } else println(year + " is not a leap year."); } } Now, this is how I calculated the leap year. import acm.program.*; public class LeapYear extends ConsoleProgram { public void run() { println("This program calculates leap year."); int year = readInt("Enter the year: "); if ((year % 4 == 0) && year % 100 != 0) { println(year + " is a leap year."); } else if ((year % 4 == 0) && (year % 100 == 0) && (year % 400 == 0)) { println(year + " is a leap year."); } else { println(year + " is not a leap year."); } } } Is there anything wrong with my code or should i use the one provided by the book ? EDIT :: Both of the above code works fine, What i want to ask is which code is the best way to calculate the leap year.

  • Is there a software like AutoCAD, but only 2D, not 3D?

    - by Saeed Neamati
    I love AutuCAD. It's powerful, easy to use, and fits engineering mind. It rocks when you want to draw 2D diagrams and shapes and one the cool features I like about it, is its snapping power. You draw a simple rectangle, then you can very easily create a circumscribe circle around it. However, new version of it are becoming really heavy (in size) and need high tech hardware, because of its powerful 3D capabilities, and rendering engines coming with it. I only want the 2D part of AutoCAD. Is there any software out there, which resembles AutoCAD (like having a console, where you can type L and get the line tool, or having snapping capability, etc.), but is small in size? In other words, what software can be named as AutoCAD 2D alternative?
