• Its all working so now I can chill

  - by bizl

  Most software houses I have been at have this attitude about their work. Get it done quick and move on. For programmers I find that the chill time is time that can be used to either improve infrastructure, refactor some old code or learn a new language. I would like to know what your throughts about 'chill time' if its the right attitude at all, and if so what to do with it. Is this sort of chilling helpful for a programmer, what are things you do with your own chill time if you adopt this approach to work.

• Why should I reuse XmlHttpRequest objects?

  - by Xavi

  From what I understand, it's a best practice to reuse XmlHttpRequest objects whenever possible. Unfortunately, I'm having a hard time understanding why. It seems like trying to reuse XHR objects can increase code complexity, introduce possible browser incompatibilities, and lead to other subtle bugs. After researching this question for a while, I did come up with a list of possible explanations: Fewer objects created means less garbage collecting Reusing XHR objects reduces the chance of memory leaks The overhead of creating a new XHR object is high The browser is able to perform some sort of network optimization under hood But I'm not sure if any of these reasons are actually valid. Any light you can shed on this question would be much appreciated.

• How does Rails find models and controllers? How can I get it to load more models?

  - by David

  I'm trying to create a non-ActiveRecord model in app/models/gamestate.rb. Then inside my controller (PlayController) I should be able to do GameState.new, right? No go: NameError (uninitialized constant PlayController::GameState): app/controllers/play_controller.rb:23:in `play' (at least in the development environment) But! If I do have a model called app/models/play.rb, then it's automatically loaded and I can do Play.new. So my question is: how does Rails know which classes to load? What sort of name mangling does it do to get from play#action to PlayController to app/controllers/play_controller.rb to app/models/play.rb? It seems awfully fragile, but maybe a better understanding of how this works would help. And finally, how can I get it to load app/models/gamestate.rb?

• CPU/GPU Monitering. (Tempature, current speed, etc) in C#

  - by Tommy

  Im looking for a way to moniter system statistics, here are my main points of interest: CPU Tempature CPU speed, (Cycles per second) CPU Load (Idle percent) GPU Tempature Some other points of interest: Memory useage Network Load (Traffic Up/Down) My ultimate goal is to write an application that can be used for easily running in the backround, and allow setting many events fr certain actions, for instance When processer temp gets to 56C -> Do _Blank_ etc. So this leaves me two main points. Is there a framework already out there for this sort of thing? If No to #1, How can i go about doing this?

• Need some clarification with Patterns (DAO x Gateway)

  - by Marcos Placona

  Me and my colleagues got into this discussion early this morning, and our opinions started to clash a bit, so I decided to get some impartial advice here. One of my colleagues reckons that the DAO should return an object (populated bean). I think it's completely fine when you're returning a recordset with only one line, but think it's overkill if you have to return 10 lines, and create 10 separate objects. I on the other see that the difference between DAO and Gateway pattern is that the gateway pattern will allow you to return a recordset to your business class, which will therefore deal with the recordset data and do whatever it needs to do. My questions here are: Which assumptions are correct? What should the return type be for a DAO (i.e. getContact() - for one record) Should getContacts() (for multiple records) even be on the DAO, if so, what's it's returntype? We seem to be having some sort of confusion about DAO and Gateway Patterns. Should they be used together? Thanks in advance

• ruby / rails boolean method naming conventions

  - by Dennis

  I have a short question on ruby / rails method naming conventions or good practice. Consider the following methods: # some methods performing some sort of 'action' def action; end def action!; end # some methods checking if performing 'action' is permitted def action?; end def can_action?; end def action_allowed?; end So I wonder, which of the three ampersand-methods would be the "best" way to ask for permissions. I would go with the first one somehow, but in some cases I think this might be confused with meaning has_performed_action?. So the second approach might make that clearer but is also a bit more verbose. The third one is actually just for completeness. I don't really like that one. So are there any commonly agreed-on good practices for that?

• Python list as *args?

  - by Cap

  I have two Python functions, both of which take variable arguments in their function definitions. To give a simple example: def func1(*args): for arg in args: print arg def func2(*args): return [2 * arg for arg in args] I'd like to compose them -- as in func1(func2(3, 4, 5)) -- but I don't want args in func1 to be ([6, 7, 8],), I want it to be (6, 7, 8), as if it was called as func1(6, 7, 8) rather than func1([6, 7, 8]). Normally, I would just use func1(*func2(3, 4, 5)) or have func1 check to see if args[0] was a list. Unfortunately, I can't use the first solution in this particular instance and to apply the second would require doing such a check in many places (there are a lot of functions in the role of func1). Does anybody have an idea how to do this? I imagine some sort of introspection could be used, but I could be wrong.

• virtualenv on Windows: not over-riding installed package

  - by Tom

  My current setup is Python 2.5/ Django 1.1.1 on Windows. I want to start using Django 1.2 on some projects, but can't use it for everything. Which is just the sort of thing I've got virtualenv for. However, I'm running into a problem I've never encountered and it's hard to Google for: installing Django 1.2 into a virtualenv has no effect for me. If I then activate the environment and do python import django django.VERSION I get "1.1.1 Final". Django is installed in the site-packages directory of my environment and the init file in the root shows that it is 1.2. But the environment falls back to 1.1.1, even if I create the environment with the --no-site-packages flag. What am I screwing up?

• Auto-versioning of static content with JBoss

  - by Bears will eat you

  As per the Q&A here, I'd like to implement a similar auto-versioning system for a web app running in JBoss 5. Is there anything already out there to do this sort of thing, or will I need to write something myself? To be clear: I am not using PHP. Not knowing much about PHP, I'm not sure what the Tomcat/JBoss analogs of PHP's .htaccess, etc. are. If I do have to write my own auto-versioning, where would I start? The principle is clear to me - rewriting the URL using the file's timestamp, but I don't know much about URL rewriting with JBoss/Tomcat.

• create a queue of process in classic asp

  - by austin powers

  Hi, here is the problem : there is classic asp app which is calling lame.exe for encoding mp3s for lots of time per day and there is no control of the way of calling lame.exe from several users in another word there is no queue for that purpose. so here is what I am thinking about : //below code all are pseudo-code //process_flag and mp3 and processId all are reside in a database function addQ(string mp3) add a record to database and set process_flag to undone then goto checkQ end function function checkQ() if there is a process in queue list sort in by processID asc for each processID processQ(processID) end for end function function ProcessQ(int processID) run lame.exe with the help of wscript.exe after doing the job set the process_flag to done end function so I just want to know is there any better solution? or any other approaches out there? regards.

• locking database record for editing

  - by sd_dracula

  I have a SQL 2008 DB and an asp.net frontend. I would like to implement a lock when a user is currently editing a record but unsure of which is the best approach. My idea is to have a isLocked column for the records and it gets set to true when a user pulls that record, meaning all other users have read only access until the first user finishes the editing. However, what if the session times out and he/she never saves/updates the record, the record will remain with isLocked = true, meaning others cannot edit it, right? How can I implement some sort of session time out and have isLocked be automatically set to false when the session times out (or after a predefined period) Should this be implemented on the asp.net side or the SQL side?

• PHP Linefeeds (\n) Not Working

  - by dosboy

  For some reason I can't use \n to create a linefeed when outputting to a file with PHP. It just writes "\n" to the file. I've tried using "\\n" as well, where it just writes "\n" (as expected). But I can't for the life of me figure out why adding \n to my strings isn't creating new lines. I've also tried \r\n but it just appends "\r\n" to the line in the file. Example: error_log('test\n', 3, 'error.log'); error_log('test2\n', 3, 'error.log'); Outputs: test\ntest2\n Using MAMP on OSX in case that matters (some sort of PHP config thing maybe?). Any suggestions?

• Understanding run time code interpretation and execution

  - by Bob

  I'm creating a game in XNA and was thinking of creating my own scripting language (extremely simple mind you). I know there's better ways to go about this (and that I'm reinventing the wheel), but I want the learning experience more than to be productive and fast. When confronted with code at run time, from what I understand, the usual approach is to parse into a machine code or byte code or something else that is actually executable and then execute that, right? But, for instance, when Chrome first came out they said their JavaScript engine was fast because it compiles the JavaScript into machine code. This implies other engines weren't compiling into machine code. I'd prefer not compiling to a lower language, so are there any known modern techniques for parsing and executing code without compiling to low level? Perhaps something like parsing the code into some sort of tree, branching through the tree, and comparing each symbol and calling some function that handles that symbol? (Wild guessing and stabbing in the dark)

• My Ruby Code: How can I improve? (Java to Ruby guy)

  - by steve

  Greetings, I get the feeling that I'm using ruby in an ugly way and possibly missing out on tonnes of useful features. I was wondering if anyone could point out a cleaner better way to write my code which is pasted here. The code itself simply scrapes some data from yelp and processes it into a json format. The reason I'm not using hash.to_json is because it throws some sort of stack error which I can only assume is due to the hash being too large (It's not particularly large). Response object = a hash text = the output which saves to file Anyways guidance appreciated. def mineLocation client = Yelp::Client.new request = Yelp::Review::Request::GeoPoint.new(:latitude=>13.3125,:longitude => -6.2468,:yws_id => 'nicetry') response = client.search(request) response['businesses'].length.times do |businessEntry| text ="" response['businesses'][businessEntry].each { |key, value| if value.class == Array value.length.times { |arrayEntry| text+= "\"#{key}\":[" value[arrayEntry].each { |arrayKey,arrayValue| text+= "{\"#{arrayKey}\":\"#{arrayValue}\"}," } text+="]" } else text+="\"#{arrayKey}\":\"#{arrayValue}\"," end } end end

• Sticky Footers that move down when dynamic content gets loaded

  - by Dominic Rodger

  I've been using this snippet of jQuery to get a sticky footer: if($(document.body).height() < $(window).height()){ $("#footer").css({position: "absolute",top:($(window).scrollTop()+$(window).height()-$("#footer").height())+"px", width: "100%"}); } $(window).scroll(positionFooter).resize(positionFooter); However, that breaks when I've got expandable/collapsible divs lying around where the original content was less high than the window, since it is then stuck to the bottom of the window, rather than the bottom of the document. Is there a way of fixing this, or a better way of doing it? Please bear in mind that I don't have much control over the HTML, since I need to do this in Django's admin interface, which doesn't allow much injection of HTML in the places you might want to to accomplish this sort of thing (i.e. this answer and this answer don't work for me).

• Avoiding string copying in Lua

  - by Matt Sheppard

  Say I have a C program which wants to call a very simple Lua function with two strings (let's say two comma separated lists, returning true if the lists intersect at all, false if not). The obvious way to do this is to push them onto the stack with lua_pushstring, which works fine, however, from the doc it looks like lua_pushstring but makes a copy of the string for Lua to work with. That means that to cross over to the Lua function is going to require two string copies which I could avoid by rewriting the Lua function in C. Is there any way to arrange things so that the existing C strings could be reused on the Lua side for the sake of performance (or would the strcpy cost pale into insignificance anyway)? From my investigation so far (my first couple of hours looking seriously at Lua), lite userdata seems like the sort of thing I want, but in the form of a string.

• Do you know of a bleeding-edge HTML5 leveraging, legacy-ignoring JavaScript framework?

  - by Ivan

  What's the best framework (sort of jquery, extjs, etc like) to use if I'd like to intensively use all the freshest technologies of the HTML5 stack provided by modern browsers (Firefox 3.6+ (Minefield especially), Safari 4+, Chrome 4+) and have absolutely no need to support any legacy browsers (incl. no need in IE support at all, no need in Firefox prior to 3.5, etc.)? I'd like to get all the newest available goodness without having (even abstracted by a library layer) a line of code meant just fore legacy compatibility and keeping no legacy-induced things in mind. To soften the filter, taking very humble hope of such an ideally fresh framework to exist, the least (the maximum level of legacy support) I'd like to agree is not supporting IE versions older than IE8, or better just not supporting IE at all.

• What is the performance impact of tracing in C# and ASP.NET?

  - by SkippyFire

  I found this in some production login code I was looking at recently... HttpContext.Current.Trace.Write(query + ": " + username + ", " + password)); ...where query is a short SQL query to grab matching users. Does this have any sort of performance impact? I assume its very small. Also, what is the purpose of this exact type of trace, using the HTTP Context? Where does this data get traced to? Thanks in advance!

• Python command line UI

  - by hdx

  Hey guys/gals I'm writing a python script that fixes some duplicate issues on my database. I would like to display some progress status to the users, currently I just print it like this: print "Merged " + str(idx) + " out of " + str(totalCount); The problem is that it prints that in a new line for every record and that does not look so good :) I'd like to either always print the string above on the same line on the screen or use some smart widget that displays it in some sort of progress bar. I intent to run this on the command line, any suggestions will be much appreciated.

• htaccess, remove text from url

  - by Keiron Lowe

  Here is the email from the client explaining what he is trying to do, we have spent hours trying to sort out this problem but cannot find a solution that works. I am trying to correct a problem with my blog and google “not found” URLs. I thought it might be very simple to correct (!ha!) This is my line of code; RewriteCond %{THE_REQUEST} ^www.uk-domestic-cleaning.com/wpblog/tag/?(.*)/HomeMaid%20Domestic%20Cleaning$ RewriteRule ^wpblog\/tag\/?(.*)\/HomeMaid%20Domestic%20Cleaning$ "http\:\/\/www\.uk\-domestic\-cleaning\.com\/wpblog\/tag\/$1" [R=301,L] What I am trying to do is any request to */wplog/tag/ “anything here”/HomeMaid Domestic Cleaning To strip the “HomeMaid Domestic Cleaning” bit off the end, but leave the rest of the request intact, which will then be a valid request. Any idea's guys?

• Use a template parameter in a preprocessor directive?

  - by Ranju V

  Is it possible to use a non-type constant template parameter in a preprocessor directive? Here's what I have in mind: template <int DING> struct Foo { enum { DOO = DING }; }; template <typename T> struct Blah { void DoIt() { #if (T::Doo & 0x010) // somecode here #endif } }; When I try this with something like Blah<Foo<0xFFFF>>, VC++ 2010 complains something about unmatched parentheses in the line where we are trying to use "#if". I am guessing the preprocessor doesn't really know anything about templates and this sort of thing just isn't in its domain. What say? Thanks!

• Java's TreeSet equivalent in Python?

  - by viksit

  I recently came across some Java code that simply put some strings into a Java TreeSet, implemented a distance based comparator for it, and then made its merry way into the sunset to compute a given score to solve the given problem. My questions, Is there an equivalent data structure available for Python? The Java treeset looks basically to be an ordered dictionary that can use a comparator of some sort to achieve this ordering. I see there's a PEP for Py3K for an OrderedDict, but I'm using 2.6.x. There are a bunch of ordered dict implementations out there - anyone in particular that can be recommended? Thanks.

• How to efficiently handle Where and OrderBy clauses

  - by Goran

  My business layer passes all the required information to UI layer. From what I have read, in general, best practice is to send fetched data to UI layer, and to avoid passing queries like ObjectQuery. My problem with this approach is next: If I am to make a flexible business layer, then I should allow UI to sort the data anyway it requires. Fetching sorted data from database, and then resorting them in UI is kind of bad practice for me, so the only way is to somehow So what are my options? Is there a way to make it like this: public void OrderByMethod(params ...) { .... } so I can call it like this: OrderByMethod(MyEntity.Property1, MyEntity.Property2 descending....); Thanks, Goran

• css anchor div to foot of page

  - by foxed

  I may bounce my head off the wall shortly, I can't believe that something as stupid as this has utterly defeated me ... therefore I turn to you, Stack Overflow ... for guidance and enlightenment. Problem: Sit div at foot of page, 100% width, outside of any sort of wrapper. Proposed Solution: http://ryanfait.com/sticky-footer/ Implementation with content: http://www.weleasewodewick.com/redesign/index_content.html Implementation with no content: http://www.weleasewodewick.com/redesign/index.html with content - Good, works nicely no content = bad, footer sits exactly height of footer below the viewport. I really would appreciate your input into this, it's completely vexed me for the past hour. I wholly expect some form of ridicule :) Thanks! Foxed

• How do I get Mathematica to thread a 2-variable function over two lists, using functional programmin

  - by Leah Wrenn Berman

  Lets say I have a function f[x_, y_], and two lists l1, l2. I'd like to evaluate f[x,y] where x runs over the list l1 and y runs over the list l2, and I'd like to do it without having to make all pairs of the form {l1[[i]],l2[[j]]}. (Motivation: I'm trying to implement some basic Haskell programs in Mathematica. In particular, I'd like to be able to code the Haskell program isMatroid::[[Int]]->Bool isMatroid b =and[or[sort(union(xs\\[x])[y]'elem'b|y<-ys]|xs<-b,ys<-b, xs<-x] I think I can do the rest of it, if I can figure out the original question, but I'd like the code to be Haskell-like. Any suggestions for implementing Haskell-like code in Mathematica would be appreciated.)
