  • What is a good way to refactor a large, terribly written code base by myself? [closed]

    - by AgentKC
    Possible Duplicate: Techniques to re-factor garbage and maintain sanity? I have a fairly large PHP code base that I have been writing for the past 3 years. The problem is, I wrote this code when I was a terrible programmer and now it's tens of thousands of lines of conditionals and random MySQL queries everywhere. As you can imagine, there are a ton of bugs and they are extremely hard to find and fix. So I would like a good method to refactor this code so that it is much more manageable. The source code is quite bad; I did not even use classes or functions when I originally wrote it. At this point, I am considering rewriting the whole thing. I am the only developer and my time is pretty limited. I would like to get this done as quickly as possible, so I can get back to writing new features. Since rewriting the code would take a long time, I am looking for some methods that I can use to clean up the code as quickly as possible without leaving more bad architecture that will come back to haunt me later. So this is the basic question: What is a good way for a single developer to take a fairly large code base that has no architecture and refactor it into something with reasonable architecture that is not a nightmare to maintain and expand?

  • Am I harming myself by having two domains pointing at the same thing?

    - by Earlz
    I have a domain I recently purchased. I went ahead and pointed it at my website(via DNS) and by default, my server now serves my website on this new domain. Eventually, the new domain will replace my old domain(with 302 redirects and all that). However, I've not yet got my website ready for that because I'll need to do some rebranding and such. Am I actively hurting my SEO ratings and such by having these two domains point to the same thing?

  • My monitor made a noise and is now dimmer - can I repair this myself?

    - by Ross
    I have a Samsung SyncMaster T190 LCD monitor which I've had for about 5 years. It hissed slightly then went dim (readable but the top half of the screen is less bright). I'm pretty sure that after 5 years of service it's just got to the point where something's burned out, so my question is can I repair this myself, or should I just get a new monitor. I'm currently a student so self repair would be a better option if cost effective.

    - by user74850
    Hi everybody, My host relay is working but I was aksed to add a new domain (like external.example.com). I have added in main.cf the new fqdn in relay_domains relay_domains = $mydestination, example.com,example2.com, externe.example.com and in transport example.com smtp:[192.168.1.22] example2.com smtp:[192.168.1.22] external.example.com smtp:[192.168.1.22] Mails sent to users with example.com and example2.com domain are well delivered. But for mails to external.example.com i got this message Mar 17 16:47:52 relayhost postfix/smtp[11948]: 754E1876A01: to=<[email protected]>, relay=relayhost2.example.com[80.81.82.83]:25, delay=19555, delays=19525/0.01/30/0, dsn=4.4.6, status=deferred (mail for external.example.com loops back to myself) I read another Q/A about the same issue right here, but it's not helping me. Can you ?

  • logrotate> removing delaycompress function: should I compress the last log myself?

    - by user120006
    I'm removing the delaycompress function from my logrotating script. Before running logrotate again, should I compress the last log myself ? This is the actual situation: -rw-r----- 1 root adm 4,7M 5 mag 18:38 access.log -rw-r----- 1 root adm 5,2M 29 apr 05:44 access.log.1 -rw-r----- 1 root adm 473K 22 apr 05:45 access.log.2.gz -rw-r----- 1 root adm 605K 15 apr 05:44 access.log.3.gz -rw-r----- 1 root adm 588K 8 apr 05:44 access.log.4.gz The question is: Should I compress "access.log.1" and THEN launch logrotate ? Or logrotate will understand I removed the "delaycompress" option and fix things himself ?

  • How do I prepare myself for a summer of working on Python using Linux environment?

    - by Shailesh Tainwala
    Hi, I have used just Windows for programming so far. Now, I have an internship starting in two weeks and I will be using just Linux environment with Python programming language. I've installed Ubuntu on my system but have no exposure to shell scripting. I need some advice on how I can quickly learn to use the Linux terminal quickly. Any books or web resources that you can suggest? Also, is there a particular IDE that is generally preferred for Python programming on Linux, or is Vim preferred? How can I best prepare myself for the internship ahead? Thanks for taking the time.

  • Which opensource license to use to retain commercial rights for myself.

    - by Quigrim
    I am starting an opensource project. I want to allow the following: Free for noncommercial use, bins and source mods, like with the GPL, but I would like to retain commercial rights for myself, and provide another license for commercial use for customers who prefer that option. The number of licensing options seem a bit overwhelming. So my question is: Which opensource license should I use? Which commercial license should I use, if there are any standard ones available? Or should I come up with my own one here?

  • Is it possible to have WAMP run httpd.exe as user [myself] instead of local SYSTEM?

    - by Olivier H
    Hello! I run a django application over apache with mod_wsgi, using WAMP. A certain URL allows me to stream the content of image files, the paths of which are stored in database. The files can be located whether on local machine or under network drive (\my\network\folder). With the development server (manage.py runserver), I have no trouble at all reading and streaming the files. With WAMP, and with network drive files, I get a IOError : obviously because the httpd instance does not have read permission on said drive. In the task manager, I see that httpd.exe is run by SYSTEM. I would like to tell WAMP to run the server as [myself] as I have read and write permissions on the shared folder. (eventually, the production server should be run by a 'www-admin' user having the permissions) Mapping the network shared folder on a drive letter (Z: for instance) does not solve this at all. The User/Group directives in httpd.conf do not seem to have any kind of influence on Apache's behaviour. I've also regedited : I tried to duplicate the HKLM[...]\wampapache registry key under HK_CURRENT_USER\ and rename the original key, but then the new key does not seem to be found when I cmd this > httpd.exe -n wampapache -k start or when I run WAMP. I've run out of ideas :) Has anybody ever had the same issue?

  • How do I stop myself from redesigning my Silverlight screens? Is there a theme that looks like Sket

    - by Dan Ryan
    Whilst working in Silverlight I am always fighting the urge to work on the screen design rather than coding the behaviour (which is what I should be doing). My cunning plan is to find a theme that looks something like MS SketchFlow or Balsamiq which will remind me of the draft nature of the screens whilst being somewhat prettier than the default look & feel of Silverlight. Does anyone know of such a theme? Alternatively can anyone give advise on how they overcame there design addiction :) Thanks, Dan

  • CSS Design question, I've got myself completely turned around.

    - by Matt Dawdy
    Okay, I have a couple of other questions out there, but I think I'd better just ask from the beginning how you CSS experts would do this. Client's page is split into 2 rows -- header has some info, some aligned to left of page, some to right, some in the middle. This is currently done using a table. I'm fine with leaving this alone or changing it. My real question is that I need a page layout to handle the following: 2 columns - column on left is 200px, but can be "close" down to to 10px (not a slider, it's either 200 or 10 px). The column on the right needs to be as big as it needs to be -- which might be larger than the width of the page. When left column is "closed" then the right column slides over of course. Again, this right column might be 300px or it might be 4000 pixels (it's a reporting interface). Now, to add another wrinkle, SOME pages have 3 columns. The first 2 columns are each exactly 200px, and both can be "closed" down to 10 px each. But, the user may not close both columns, maybe just 1. Or none. Or both. The third column needs to act just like I described above, being able to be larger than the page width, and sliding over to take advantage of any of the "closed" left columns. Whew! I'm pretty confused as to how to go about this, as either I get it right but I can't scroll over to the right at all (overflow: hidden) and information is lost, or the right column jumps down below the left 2 columns and just looks plain stupid. My minimum browser requirements are IE8, FF3.5, Chrome and Safari (latest versions of all). Any and all pointers are gladly accepted.

  • In Django, I want to insert a database record by sending myself an email?

    - by littlejim84
    Hello. I'm looking into a possible feature for my little to-do application... I like the idea that I can send an email to a particular email address, containing a to-do task I need to complete, and this will be read by my web application and be put in the database... So, when I come to log into my application, the to-do task I emailed will be there as a entry in the app. Is this possible? I have a slice with SliceHost (basically a dedicated server) so I have total control on what to install etc. I'm using Python/Django/MySQL for this. Any ideas on what steps to take to make this happen?

  • How can i see if dealloc is being called on a uikit object, or any object not created by myself

    - by Gyozo Kudor
    I think i have an UIImage that has a higher retain count than it should have and i am probably leaking memory. I use this image as a thumbnail, to set a custom background to a uibutton. So the uibutton is holding a reference to it and so do i. But instead of 2, the retainCount is 3. Do i have to create a custom UIImage derived class and override dealloc if I want to place a log message there and then change the class used from UIImage to my class, or is there an easier way. Thanks in advance.

  • How To Send A Confirmation Number To Others And Myself?

  • How to reconcile my support of open-source software and need to feed and house myself?

    - by Guzba
    I have a bit of a dilemma and wanted to get some other developers' opinions on it and maybe some guidance. So I have created a 2D game for Android from the ground up, learning and re factoring as I went along. I did it for the experience, and have been proud of the results. I released it for free as ad supported with AdMob not really expecting much out of it, but curious to see what would happen. Its been a few of months now since release, and it has become very popular (250k downloads!). Additionally, the ad revenue is great and is driving me to make more good games and even allowing me to work less so that I can focus on my own works. When I originally began working on the game, I was pretty new to concurrency and completely new to Android (had Java experience though). The standard advice I got for starting an Android game was to look at the sample games from Google (Snake, Lunar Lander, ...) so I did. In my opinion, these Android sample games from Google are decent to see in general what your code should look like, but not actually all that great to follow. This is because some of their features don't work (saving game state), the concurrency is both unexplained and cumbersome (there is no real separation between the game thread and the UI thread since they sync lock each other out all the time and the UI thread runs game thread code). This made it difficult for me as a newbie to concurrency to understand how it was organized and what was really running what code. Here is my dilemma: After spending this past few months slowly improving my code, I feel that it could be very beneficial to developers who are in the same position that I was in when I started. (Since it is not a complex game, but clearly coded in my opinion.) I want to open up the source so that others can learn from it but don't want to lose my ad revenue stream, which, if I did open the source, I fear I would when people released versions with the ad stripped, or minor tweaks that would fragment my audience, etc. I am a CS undergrad major in college and this money is giving me the freedom to work less at summer job, thus giving me the time and will to work on more of my own projects and improving my own skills while still paying the bills. So what do I do? Open the source at personal sacrifice for the greater good, or keep it closed and be a sort of hypocritical supporter of open source?

  • What should I do or learn to better prepare myself for a co-op position?

    - by Chris Vinz
    I'm currently taking computer systems in a technical institute and I will start looking for a coop job by next September. Since summer vacation is only a few weeks away, I was wondering what I should learn or do to help me land a job and do well in it. I'm pretty sure I'm ahead of most of my classmates since I got around 1.5 years "head start." For now, I'm planning to learn how to use source control (git - for no reason really) and was actually thinking of learning Scheme through SICP and maybe build something nice with it at the end. On the other hand, I'm wondering if it's better to expand on what I know right now and I'm thinking of C++ since I enjoy it a lot more than others like Java. Can I get advice on this? thanks!

  • How do I reset my Ubuntu user password?

    - by Myself
    I lost my Ubuntu user account password... I saw some other questions on this topic that had answers telling me to restart the computer, press the left shift key after BIOS, go to root, type "passwd [username]" and all this other stuff, but none of that worked. After I typed a new password and retyped it, it gave me an error message saying something like "Authentication Manipulation Error." There was another question complaining about this, but there weren't any useful answers that worked. Does anybody know of a way for me to retrieve or reset my password? Am I doing something wrong with that method I mentioned?

  • Depending on another open source library: copy/paste code or include

    - by user5794
    I'm working on a large class and started implementing new features that need graphics. I started writing the graphics functions myself, but I know that open source libraries exist that can provide me with this functionality without me having to write it myself. The problem is that I prefer the class to be self-sufficient and not dependent on any other library. If I don't write it myself, I would have to ask the user to make sure a graphics library is already installed (less user-friendly). If I write it myself, I do a lot more work than I have to. I could also copy/paste some of the relevant code into my own class, but not sure about the disadvantages of doing this (it's an open source library that matches my license, so I'm not concerned with legality, just programming-wise if there are disadvantages). So what should I do: copy paste code from the external library write the code myself so it's truly self-sufficient ask the user to download and install another library

  • Why does multiple calls to xalloc result in delayed output?

    - by Me myself and I
    When I print the id of a stream in a single expression it prints it backwards. Normally this is what comes out: std::stringstream ss; std::cout << ss.xalloc() << '\n'; std::cout << ss.xalloc() << '\n'; std::cout << ss.xalloc(); Output is: 4 5 6 But when I do it in one expression it prints backwards, why? std::stringstream ss; std::cout << ss.xalloc() << '\n' << ss.xalloc() << '\n' << ss.xalloc(); Output: 6 5 4 I know the order of evaluation is unspecified but then why does the following always result in the correct order: std::cout << 4 << 5 << 6; Can someone explain why xalloc behaves differently? Thanks.

  • I love programming but never get projects started

    - by 0xHenry
    I read this question and the most voted answer and said to myself "Those things are what I want to do! But why the heck I'm not doing it?" The problem here is that I can't get anything started. I hope you get some kind of idea what I'm interested in and can help me continue programming. I'm interested in embedded programming and I'd like to learn some ARM assembly. I think those could be combined with image processing. Also I'd love to create programs that are actually useful to some people but it seems like there are already multiple programs for pretty much every purpose. Maybe if I found an interesting program without open source alternatives I could get a great project to work on. How could I get myself to finally start a project or few and keep myself interested in them? I just want to get myself to do something I love.
