  • How do I prove or disprove "god" objects are wrong?

    - by honestduane
    Problem Summary: Long story short, I inherited a code base and an development team I am not allowed to replace and the use of God Objects is a big issue. Going forward, I want to have us re-factor things but I am getting push-back from the teams who want to do everything with God Objects "because its easier" and this means I would not be allowed to re-factor. I pushed back citing my years of dev experience, that I'm the new boss who was hired to know these things, etc, and so did the third party offshore companies account sales rep, and this is now at the executive level and my meeting is tomorrow and I want to go in with a lot of technical ammo to advocate best practices because I feel it will be cheaper in the long run (And I personally feel that is what the third party is worried about) for the company. My issue is from a technical level, I know its good long term but I'm having trouble with the ultra short term and 6 months term, and while its something I "know" I cant prove it with references and cited resources outside of one person (Robert C. Martin, aka Uncle Bob), as that is what I am being asked to do as I have been told having data from one person and only one person (Robert C Martin) is not good enough of an argument. Question: What are some resources I can cite directly (Title, year published, page number, quote) by well known experts in the field that explicitly say this use of "God" Objects/Classes/Systems is bad (or good, since we are looking for the most technically valid solution)? Research I have already done: I have a number of books here and I have searched their indexes for the use of the words "god object" and "god class". I found that oddly its almost never used and the copy of the GoF book I have for example, never uses it (At least according to the index in front of me) but I have found it in 2 books per the below, but I want more I can use. I checked the Wikipedia page for "God Object" and its currently a stub with little reference links so although I personally agree with that it says, It doesn't have much I can use in an environment where personal experience is not considered valid. The book cited is also considered too old to be valid by the people I am debating these technical points with as the argument they are making is that "it was once thought to be bad but nobody could prove it, and now modern software says "god" objects are good to use". I personally believe that this statement is incorrect, but I want to prove the truth, whatever it is. In Robert C Martin's "Agile Principles, Patterns, and Practices in C#" (ISBN: 0-13-185725-8, hardcover) where on page 266 it states "Everybody knows that god classes are a bad idea. We don't want to concentrate all the intelligence of a system into a single object or a single function. One of the goals of OOD is the partitioning and distribution of behavior into many classes and many function." -- And then goes on to say sometimes its better to use God Classes anyway sometimes (Citing micro-controllers as an example). In Robert C Martin's "Clean Code: A Handbook of Agile Software Craftsmanship" page 136 (And only this page) talks about the "God class" and calls it out as a prime example of a violation of the "classes should be small" rule he uses to promote the Single Responsibility Principle" starting on on page 138. The problem I have is all my references and citations come from the same person (Robert C. Martin), and am from the same single person/source. I am being told that because he is just one guy, my desire to not use "God Classes" is invalid and not accepted as a standard best practice in the software industry. Is this true? Am I doing things wrong from a technical perspective by trying to keep to the teaching of Uncle Bob? God Objects and Object Oriented Programming and Design: The more I think of this the more I think this is more something you learn when you study OOP and its never explicitly called out; Its implicit to good design is my thinking (Feel free to correct me, please, as I want to learn), The problem is I "know" this, but but not everybody does, so in this case its not considered a valid argument because I am effectively calling it out as universal truth when in fact most people are statistically ignorant of it since statistically most people are not programmers. Conclusion: I am at a loss on what to search for to get the best additional results to cite, since they are making a technical claim and I want to know the truth and be able to prove it with citations like a real engineer/scientist, even if I am biased against god objects due to my personal experience with code that used them. Any assistance or citations would be deeply appreciated.

  • Troubleshooting Your Network with Oracle Linux

    - by rickramsey
    Are you afraid of network problems? I was. Whenever somebody said "it's probably the network," I went to lunch. And hoped that it was fixed by the time I got back. Turns out it wasn't that hard to do a little basic troubleshooting Tech Article: Troubleshooting Your Network with Oracle Linux by Robert Chase You're no doubt already familiar with ping. Even I knew how to use ping. Turns out there's another command that can show you not just whether a system can respond over the network, but the path the packets to that system take. Our blogging platform won't allow me to write the name down, but I can tell you that if you replace the x in this word with an e, you'll have the right command: tracxroute Once you get used to those, you can venture into the realms of mtr, nmap, and netcap. Robert Chase explains how each one can help you troubleshoot the network, and provides examples for how to use them. Robert is not only a solid writer, he is also a brilliant motorcyclist and rides an MV Augusta F4 750.

  • Improving the speed of writing code in C#

    - by Robert Harvey
    Laugh if you want, but I used to develop substantial line-of-business applications in VB6, long before the .NET framework came along. Why, when I was your age, we used to walk two miles in the snow, uphill. Both ways... Love it or hate it, VB6 had a REPL-like feel, and a very rapid development cycle. I would like to know how to come closer to that process in C#. In VB6, I could write a function, execute it, debug it and have it fully functional in a few minutes. I am told this is how the Lisp crowd works. It's a very rapid-fire style of programming. In C# I write a function, then I write a unit test for that function (which is OK, I understand the value of that), then I right-click, run test, wait for the project to compile (takes about 10 seconds right now, which would be an eternity for a REPL loop), and get an exception. Honestly, this feels more like my junior college days, when I used to feed punch cards into a hopper and wait for a printout (exaggerating only slightly for effect). Additionally, my tendency nowadays is to make everything public while I'm testing it. Unit testing with private accessors works fine, but you can't trace through the code (unless, of course, I'm doing something wrong) while you're using them. So what I'd like to know is, what adjustments have you made to your development process in C# to streamline it, and make it possible to write and verify your code very rapidly?

  • How to fix corrupted desktop icons and fonts?

    - by David Harvey
    I love Linux, but am a real novice. I installed Ubuntu 12.04 LTS 32bit alongside Windows XP. The installation seems to work just fine except for the desktop. The icons & font becomes corrupted to the point that it looks like Chinese. After surfing with Mozilla Firefox for a long time, the same problem begins with the web pages. I want to be free of Windows, but must solve this problem first. Can you help? Thank you.

  • On developing deep programming knowledge

    - by Robert Harvey
    Occasionally I see questions about edge cases and other weirdness on Stack Overflow that are easily answered by the likes of Jon Skeet and Eric Lippert, demonstrating a deep knowledge of the language and its many intricacies, like this one: You might think that in order to use a foreach loop, the collection you are iterating over must implement IEnumerable or IEnumerable<T>. But as it turns out, that is not actually a requirement. What is required is that the type of the collection must have a public method called GetEnumerator, and that must return some type that has a public property getter called Current and a public method MoveNext that returns a bool. If the compiler can determine that all of those requirements are met then the code is generated to use those methods. Only if those requirements are not met do we check to see if the object implements IEnumerable or IEnumerable<T>. That's cool stuff to know. I can understand why Eric knows this; he's on the compiler team, so he has to know. But what about those who demonstrate such deep knowledge who are not insiders? How do mere mortals (who are not on the C# compiler team) find out about stuff like this? Specifically, are there methods these folks use to systematically root out such knowledge, explore it and internalize it (make it their own)?

  • Multiple synonym dictionary matches in PostgreSQL full text searching

    - by Ryan VanMiddlesworth
    I am trying to do full text searching in PostgreSQL 8.3. It worked splendidly, so I added in synonym matching (e.g. 'bob' == 'robert') using a synonym dictionary. That works great too. But I've noticed that it apparently only allows a word to have one synonym. That is, 'al' cannot be 'albert' and 'allen'. Is this correct? Is there any way to have multiple dictionary matches in a PostgreSQL synonym dictionary? For reference, here is my sample dictionary file: bob robert bobby robert al alan al albert al allen And the SQL that creates the full text search config: CREATE TEXT SEARCH DICTIONARY nickname (TEMPLATE = synonym, SYNONYMS = nickname); CREATE TEXT SEARCH CONFIGURATION dxp_name (COPY = simple); ALTER TEXT SEARCH CONFIGURATION dxp_name ALTER MAPPING FOR asciiword WITH nickname, simple; What am I doing wrong? Thanks!

  • Embed resource in .NET Assembly without assembly prefix?

    - by Robert Fraser
    Hi all, When you embed a reosurce into a .NET assembly using Visual Studio, it is prefixed with the assembly name. However, assemblies can have embedded resources that are not assembly-name-prefixed. The only way I can see to do this is to disassemble the assembly using ildasm, then re-assemble it, adding the new resource -- which works, but... do I really need to finish that sentence? (Desktop .NET Framework 3.5, VS 2008 SP1, C#, Win7 Enterprise x64) Thanks, All the best, Robert

  • process tree

    - by Robert
    I'm looking for an easy way to find the process tree (as shown by tools like Process Explorer), in C# or other .Net language. It would also be useful to find the command-line arguments of another process (the StartInfo on System.Diagnostics.Process seems invalid for process other than the current process). I think these things can only be done by invoking the win32 api, but I'd be happy to be proved wrong. Thanks! Robert

  • Hiding Group Column Names

    - by Robert
    You once replied to a post about hiding list group header names. http://edinkapic.blogspot.com/2008/06/hiding-list-view-group-headers.html I do not write code or jQuery at that. But you mentioned that it would be better to write a solution in jQuery. Would you have code that would hide the group header and colon in a 2003 list (SP v.2)? Do you have any good leads? Thanks.

  • Great Surprise &ndash; MSDN Ultimate

    - by MarkPearl
    So, I attended the Microsoft Community Evening. The attendance was better than I was expecting for December and we had our first Programming Languages Meeting where Gary did a great presentation on an intro to Ruby. The best surprize of the evening happened when I was about to leave, Robert MacLean asked me how we did our MS licensing – the fact being that we were about to reach the end of our empower license with Microsoft and that I had no idea how we were going to afford upgrading it early next year. Well, out comes a Microsoft Visual Studio Ultimate with MSDN 12 month subscription. An absolute awesome gift – thanks Robert! Best gift ever!

  • From the Tips Box: Pin Any File to the Windows 7 Taskbar

    - by Jason Fitzpatrick
    Every week we dip into the tip box and share the tips you send in. This week we’re highlighting a great tip and the accompanying tutorial video that shows you how to pin any file to the Windows 7 taskbar. Robert Jasinski writes in with a clever way to pin any file you want to the task bar. By default if you drag a text document to the taskbar it will pin it to the Notepad executable—the same thing happens with any other file that has an association with an executable. What if you want to pin that specific text file to the taskbar and not to the executable (or any other file for that matter)?

  • I made a 2D ENGINE for Android, looking for cooperation.

    - by Roger Travis
    My name is Robert, I am an Android programmer and wanted to show off my latest project - a 2d game engine. You can see it in action here - https://play.google.com/store/apps/details?id=engineDemo.com My engine's main advantage is its ease of use. To have your level up and running, you'll need only 3 lines of code. ABoxView aboxView = new ABoxView(this); setContentView(aboxView); aboxView.loadLevel("level/level02"); Level are created in a special level constructor and object physical properties are stored in a corresponding XML file. I am looking to cooperate with those, who might be interesting in using my engine in their games. You can email me at [email protected] or post here. Thanks, Robert

  • How can i link a oracle user to a business objects user

    - by Robert Speckmann
    I have a problem with linking the oracle user to a business objects user. I will try to explain it as detailed as possible; I have a Oracle database (10g) where a couple of users are defined. These users can query on information with application X. Those records will then be written into the oracle database. The records that is written into the database has a ID that links to the person that has run the query. I also have a active directory in wich a couple of users are made; testuser1, testuser2. When those users log on, and want to load a report in Business Objects XI i want them to see the information that was created when the report was activated by that same user that had runned the query before with application X. The name of the person in the active directory and the name in the oracle database are not the same but i dont think that would be a problem in this stage. So the steps i took: First, i run a report in application X (with a account prodpim_rs) wich fills my Oracle database with a record. The second step is logging on as testuser1 (from the AD) and then login on Business Objects XI with the account. Now i want to load a report with the information in my Oracle database. So the prodpim_rs user and the testuser must have a link between them. I am wondering how to forfill this. Can i link the account, wich is made in a Oracle database, with the user of BO wich is linked to my AD? Thank you in advance for your reply Robert

  • Why have my Aperture referenced files disappeared without trace?

    - by Andy Harvey
    I have an Aperture library that I've been using for several years. In the past week a number of recent photos and movies have mysteriously disappeared. The missing files were all safely imported within the last week (I had reviewed some of the movies within Aperture, so know this to be true). The files were all referenced on an external drive. Within Aperture the files now have a "referenced file can't be found" icon. I've tried searching for the missing files manually, including within the Aperture library package, but they cannot be found anywhere. How can I (a) work out where the missing files have gone, and (b) identify the cause and ensure it doesn't happen again? I'm using Aperture 3.3.2.

  • System32 files can be deleted in Windows 2008 but not in Windows 2003 [closed]

    - by Harvey Kwok
    I have been using Windows 2003 for a long time. There is a wonderful feature. I don't know the name of it but the feature is like this. You can rename or delete some important files inside C:\windows\system32. e.g. kerberos.dll. After a while, the deleted files will be automatically recovered. I think this is because those files are criticl enough that Windows cannot survive without them. However, in Windows 2008, this feature is gone. Instead, all the files in System32 are owned by TrustedInstaller. However, as a administrator, I can still take the ownserhip of the files and then delete them. Windwos 2008 won't recover the deleted files and hence the system is screwed next time it's reboot. So, I wonder why Windows 2008 dropping that wonderful feature. Was that auto-recovery feature also suffer from some issues? Does Windows 2008 have some other features that can prevent this type of disaster from happening?
