  • The 80 column limit, still useful?

    - by Tim Post
    Related: While coding, how many columns do you format for? Is there a valid reason for enforcing a maximum width of 80 characters in a code file, this day and age? I mostly use C, however this question is language agnostic. Its also subjective, so I'll tag it as such. Many individual projects set their own various coding standards, a guide to adjust your coding style. Many enforce an 80 column limit on code, i.e. don't force a dumb 80 x 25 terminal to wrap your lines in someone else's editor of choice if they are stuck with such a display, don't force them to turn off wrapping. Both private and open source projects usually have some style guidelines. My question is, in this day and age, is that requirement more of a pest than a helper? Does anyone still login via the local console with no framebuffer and actually edit code? If so, how often and why cant you use SSH? I help to manage a few open source projects, I was considering extending this limit to 110 columns, but I wanted to get feedback first. So, any feedback is appreciated. I can see the need to make certain OUTPUT of programs (i.e. a --help /h display) 80 columns or less, but I really don't see the need to force people to break up code under 110 columns long into 2 lines, when its easier to read on one line. I can also see the case for adhering to an 80 column limit if you're writing code that will be used on micro controllers that have to be serviced in the field with a god-knows-what terminal emulator. Beyond that, what are your thoughts? Edit: This is not an exact duplicate. I am asking very specific questions, such as how many people are actually still using such a display. I am also not asking "what is a good column limit", I'm proposing one and hoping to gather feedback. Beyond that, I'm also citing cases where the 80 column limit is still a good idea. I don't want a guide to my own "c-style", I'm hoping to adjust standards for several projects. If the duplicate in question had answered all of my questions, I would not have posted this one :) That will teach me to mention it next time. Edit 2 question |= COMMUNITY_WIKI

  • ASP.NET MVC URL/Routing question

    - by Hobbes
    Hello! I am an MVC newbie. I'm trying to get my URLs to look like this: /Corporate/Users/Edit/1 /Corporate/Stores/Edit/17 /Corporate/Contacts/Edit/17 /Store/Contacts/Create /Store/Products/Edit/29 Pretty much like plain-vanilla urls, except with a user type at the front. I'm running into a lot of problems with duplicate controller names, etc. Is there a simple way to do this? I looked briefly at Areas, but this seemed way to complicated.

  • jquery - How to reference two div elements for a single function?

    - by Ben
    I Have a function that references a specific input text box. I would like to extend the function to be used by two specific input text boxes. Rather than duplicate the code for the other text box, can anyone advise on how to reference the other? Here it uses #Tags, but if i wanted it to reference #Tags2 also, how could I do that? $(function () { $('#Tags').tagSuggest({ separator: ", ", tagContainer: 'div', tags: ["tag1","tag2"] }); });

    I have a sample Solr schema as follows isPublic = boolean source = facebook| twitter | wordpress I want to write a query which returns all documents from the index which matches either the isPublic = true or isPublic is false and source= facebook. Something like this solrUrl/?q=blah&fq=(isPublic:true OR (isPublic:false AND source:facebook)) Is such a thing possible or should I search the index two times with each of these conditions and then combine + de-duplicate the results?

  • Who "invented" i,j,k as integer counter variable names? [closed]

    - by mjy
    Possible Duplicate: Why are we using i as a counter in loops I've used these myself for more than 15 years but cannot really remember how/where I picked up that habit. As it is really widespread, I'm curious to know who originally suggested / recommended using these names for integer loop counters (was it the K&R book?).

  • When would you choose C# over F#? [closed]

    - by Rosdi
    Possible Duplicate: What are the benefits of using C# vs F# or F# vs c#? There are a lot of general questions comparing functional programming vs object oriented. But I need to know the advantageous of F# over C#. Assuming you have the same skill/experience/expertise in both C# and F#, and there are no other constraints (time, team skills, etc) when would you choose C# over F# (or vice-verse)?**

What I want to do is to extract the unique maximum value x,y points For example, if I have points [1,2,5] [1,1,3] [1,2,7] [1,7,3] I would like to obtain the list [1,1,3] [1,2,7] [1,7,3] How can I do this in python Thanks

  • Fastest way to copy a set (100+) of related SQLAlchemy objects and change attribute on each one

    - by rebus
    I am developing an app that keeps track of items going in and out of factory. For example, lets say you have 3 kinds of plastic coming in, they are mixed in various ratios and then sent out as a new product. So to keep track of this I've created following database structure: This is very simplified overview of my SQLAlchemy models: IN <- RATIO <- OUT <- REPORT ITEMS -> REPORT IN are products coming in, RATIO is various information on measurements, and OUT is a final product. REPORT is basically a header model which has a lot of REPORT ITEMS attached to it, which in turn relate it to OUT products. This would all work perfectly, but IN and RATION values can change. These changes ultimately change the OUT product which would mean the REPORT values would change. So in order to change an attribute on IN object for example I should copy that object with that attribute changed. I would think this is basically a question about database normalization, because i didn't want to duplicate all the IN, RATIO and OUT information by writing it in REPORT ITEMS table for example, but I've came across this problem (well not really a problem but rather a feature I'd like for a user to have). When the attribute on IN object is changed I want related objects (RATIO and OUT) automatically copied and related to a new IN object. So I was thinking something like: Take an existing instance of model IN that needs to change (call it old_in) Create a new one out of it with some attributes changed (call it new_in) Collect all the RATIO objects that are related to old_in Copy each RATIO and relate them to a new_in Collect all the OUT objects that are related to old RATIO Copy each OUT and relate them to a new RATIO Few questions pop to mind when i look at this problem: Should i just duplicate the data, does all this copying even make sense? If it does, should i rather do it in plain SQL? If no what would be the best approach to do it with Python and SQLAlchemy? Any general answer would suffice really, at least a pointer in right direction. I really want to free then end user for hassle of having create new ratios and out products.

  • php class that auto attaches .js and .css files, possible?

    - by Haroldo
    I want the class to auto-attach its required css and js files when instantiated... is there any way of a class knowing where it is (and its files) in relation to the root? if 1 is possible, is there a way to check if a css/js file has already been referenced in the file, or is this not necessary(do browsers ignore duplicate css/js file references)?
