  • Rails 4.2: "Assets should not be requested directly without their digests"

    - by Nowaker
    On Rails 4.2.0.beta1 I get an error: Assets should not be requested directly without their digests: Use the helpers in ActionView::Helpers to request fonts/source-sans-pro.woff The stylesheet: @font-face { font-family: 'Source Sans Pro'; font-style: normal; font-weight: 400; src: local('Source Sans Pro'), local('SourceSansPro-Regular'), url(/assets/source-sans-pro.woff) format('woff'); } The configuration is: config.serve_static_assets = true config.assets.js_compressor = :uglifier config.assets.compile = true config.assets.digest = true config.assets.version = '1.0' config.assets.paths << Rails.root.join('app', 'assets', 'fonts') config.assets.precompile += %w(.svg .eot .woff .ttf) Sure I can disable digests and it works again, but I'm interested in using them. Therefore, how do I make use of digests when I need to request source-sans-pro.woff? Please note that I place the fonts in assets/fonts directory, not the public/ directory. I don't see a difference between images and fonts, so I want to keep them under the same directory - app/assets.

  • Rails/mysql SUM distinct records - optimization

    - by pepernik
    Hey. How would you optimize this SQL SELECT SUM(tmp.cost) FROM ( SELECT DISTINCT clients.id as client, countries.credits_cost AS cost FROM countries INNER JOIN clients ON clients.country_id = countries.id INNER JOIN clients_groups ON clients_groups.client_id=clients.id WHERE clients_groups.group_id IN (1,2,3,4,5,6,7,8,9) GROUP BY clients.id ) AS tmp; I'm using this example as part of my Ruby on Rails project. Note that my nested SQL (tmp) can have more then 10 milion records. You can split that in more SQLs if the performance is better. Should I add any indexes to make it quicker (i have it on IDs)?

  • Is there a free code coverage tool suitable for use with .NET 4 and NUnit?

    - by Damian Powell
    Is there a free code coverage tool suitable for use with .NET 4 and NUnit that runs from the command line (and is thus suitable for use on a build server)? Please note that any tools that require editions of Visual Studio higher than Professional are not appropriate in this case. I am asking this question because I can't get NCover 1.5.8 to work with NUnit 2.5.5 on a .NET 4 C# app. I can run the unit tests, and I can generate a Coverage.Xml file, but it is empty - it contains no sequence points. After a lot of research, I have concluded that this is because NCover 1.5.8 simply doesn't work with .NET 4. However, if you know better, please feel free to answer this question from another user.

  • UNIX-style RegExp Replace running extremely slowly under windows. Help?

    - by John Sullivan
    I'm trying to run a unix regEXP on every log file in a 1.12 GB directory, then replace the matched pattern with ''. Test run on a 4 meg file is took about 10 minutes, but worked. Obviously something is murdering performance by several orders of magnitude. Find: ^(?!.*155[0-2][0-9]{4}\s.*).*$ -- NOTE: match any line NOT starting 152[0-2]NNNN where in is a number 0-9. Replace with: ''. Is there some justifiable reason for my regExp to take this long to replace matching text, or is the program I am using (this is windows / a program called "grepWin") most likely poorly optimized? Thanks.

  • Excel - referenced values via OleDB from .Net client

    - by ho
    I'm trying to read an Excel file (.xls, I think Excel 2003 compatible) via OleDB, but it fails to get the values for referenced fields. This is my current test code (please note, this is just part of the class): Private m_conn As OleDbConnection Public Sub New(ByVal fileName As String) Dim connString As String = String.Format("Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};Extended Properties=Excel 8.0;", fileName) m_conn = New OleDbConnection(connString) m_conn.Open() End Sub Public Sub GetSheet(ByVal sheet As String) Dim query As String = String.Format("SELECT * FROM [{0}]", sheet) Using cmd As OleDbCommand = m_conn.CreateCommand() cmd.CommandText = query Dim ds As New DataSet() Dim a As New OleDbDataAdapter(cmd) Using rdr As OleDbDataReader = cmd.ExecuteReader() While rdr.Read() Debug.WriteLine(rdr.Item(0).ToString()) End While End Using End Using End Sub But if the value is a reference (something like =+'MySheetName'!K37), I just get a DBNull from the call to rdr.Item(0). I can get around this by automating Excel instead, but would prefer not to have to use Excel automation so wondering if anyone knows how to do it.

  • How can I create numbered map markers in Google Maps V3?

    - by kaneuniversal
    I'm working on a map that has multiple markers on it. These markers use a custom icon, but I'd also like to add numbers on top. I've seen how this has been accomplished using older versions of the API. How can I do this in V3? *Note -- the "title" attribute creates a tooltip when you mouseover the marker, but I want something that will be layered on top of the custom image even when you're not hovering on top of it. Here's the documentation for the marker class, and none of these attributes seem to help: http://code.google.com/apis/maps/documentation/v3/reference.html#MarkerOptions Thank you . . . . Michael

  • How do I enable automatic reloading of view files in development mode in JRuby on Rails?

    - by thekingoftruth
    I am developing an app in JRuby on Rails. For some reason, when I edit the view files, the development JRuby Mongrel server doesn't reload them. The perplexing thing is that after editing the controller files, the server reloads them just fine on the next request. This would be annoying even when using MRI Ruby, however starting up JRuby Mongrel after every view edit is much slower, and much more annoying. (Note that once it starts up it's quite fast, the only issue is startup--the JVM has to load up every time I start JRuby Mongrel.) I'm running JRuby 1.5.0, Rails 2.3.5, and Java 6.

  • How to export data which are mapped to enumerations

    - by Joshua
    I have a set of data which needs to be imported from a excel sheet, lets take the simplest example. Note: the data might eventually support uploading any locale. e.g. assuming one of the fields denoting a user is gender mapped to an enumeration and stored in the database as 0 for male and 1 for female. 0 and 1 being short values. If I have to import the values I cannot expect the user to punch in numbers (since they are not intuitive and is cumbersome when the enumerations are bigger), what would be the correct way to map to enumerations. Should we ask them to provide a string value in these cases (e.g. male or female) and provide the transformation to a enum in our code by wring a method public static Gender Gender.fromString(String value)

  • Optimizing BeautifulSoup (Python) code

    - by user283405
    I have code that uses the BeautifulSoup library for parsing, but it is very slow. The code is written in such a way that threads cannot be used. Can anyone help me with this? I am using BeautifulSoup for parsing and than save into a DB. If I comment out the save statement, it still takes a long time, so there is no problem with the database. def parse(self,text): soup = BeautifulSoup(text) arr = soup.findAll('tbody') for i in range(0,len(arr)-1): data=Data() soup2 = BeautifulSoup(str(arr[i])) arr2 = soup2.findAll('td') c=0 for j in arr2: if str(j).find("<a href=") > 0: data.sourceURL = self.getAttributeValue(str(j),'<a href="') else: if c == 2: data.Hits=j.renderContents() #and few others... c = c+1 data.save() Any suggestions? Note: I already ask this question here but that was closed due to incomplete information.

  • How to 'hide' spurious "declared but never used" warnings?

    - by Roddy
    I'm using the C++Builder compiler which has a minor bug that certain static const items from system header files can cause spurious "xyzzy is declared but never used" warnings. I'm trying to get my code 100% warning free, so want a way of masking these particular warnings (note - but not by simply turning off the warning!) Also, I can't modify the header files. I need a way of 'faking' the use of the items, preferably without even knowing their type. As an example, adding this function to my .cpp modules fixes warnings for these four items, but it seems a bit 'ad-hoc'. Is there a better and preferably self-documenting way of doing this? static int fakeUse() { return OneHour + OneMinute + OneSecond + OneMillisecond; }

    - by Shankarooni
    I am done testing my site and I want to upload it to a site like this http://www.university.edu/mydepartment/myname the admin told me the server runs on .NET 3.5. So i used Linq ... now i tried to upload the site by two ways: when i just copy everything (with modification of web.config database settings) i get an error: CS0246: The type or namespace name 'DataClassesDataContext' could not be found (are you missing a using directive or an assembly reference?) Version Information: Microsoft .NET Framework Version:2.0.50727.3082; ASP.NET Version:2.0.50727.3082 Note here it says version 2.0 did he just lie to me? or its my configuration mistake? anyway, i added the reference, nothing changes. I tried also publishing (Build, publish) with option to keep the pre-comiled site updatable, and I get one line saying: this is a makefile and should be deleted! what is going on?

  • How do I make PyScripter work? Says it cant find python26.dll

    - by Alex
    I installed PyScript to try it out but it just wont start. It only gives me the error: "Error126: Could not open Dll "python26.dll" followed by: "Python could not be properly initialized. We must quit." I think this may have something to do with the PYTHONPATH but since I'm a newbie and dont know what it is or exactly what to put in the PYTHONPATH, after some googling, I ask here. Also, when I tried to install wxPython it was impossible becouse the PYTHONPATH could not be found.(Just a side note) I have installed ActivePython 2.6 and the PATH is set so I can access python in cmd.

  • Padding a string in Postgresql with rpad without truncating it

    - by dmoebius
    Using Postgresql 8.4, how can I right-pad a string with blanks without truncating it when it's too long? The problem is that rpad truncates the string when it is actually longer than number of characters to pad. Example: SELECT rpad('foo', 5); ==> 'foo ' -- fine SELECT rpad('foo', 2); ==> 'fo' -- not good, I want 'foo' instead. The shortest solution I found doesn't involve rpad at all: SELECT 'foo' || repeat(' ', 5-length('foo')); ==> 'foo ' -- fine SELECT 'foo' || repeat(' ', 2-length('foo')); ==> 'foo' -- fine, too but this looks ugly IMHO. Note that I don't actually select the string 'foo' of course, instead I select from a column: SELECT colname || repeat(' ', 30-length(colname)) FROM mytable WHERE ... Is there a more elegant solution?

  • Correct way to close database connection in event of exception.

    /I have some code of of the following form. Does this mean the connection is left open if there is an exception?

  • Using Durable Services for saving wcf instances

    - by miker169
    I am currently creating a service which connects to a DAL and that can run a few stored procedures, one of the issues I am facing is that for certain times of the month, we can't update the database, (at the moment this is done manually. This is done via the user adding a note to their calendar) But I would like to automate this process, one of the possible solutions I can think of using is a durable service. When the date is lets say the 1st of the month, the Update/Insert/Delete instances can get saved to a database, and then ran after that date in a batch. Is this the intended use of durable services ? Is there a better route I could possibly take ?

  • Documenting software architectures that serve multiple markets

    - by wsb3383
    Hello, I'm the lead developer/architect wanna-be on a J2EE based system/platform at work that serves both real estate and automotive markets. The systems consists of a set of database back ends, web services and two web clients. The platform ends up serving 3 different products: an internal vehicle inventory system for use by company analysts, an external dealer management system (commercialized product), and a real estate inventory system (commercialized). In other words, it follows a software product lines approach....My question is, I'm having trouble communicating to other technical and some business people how this platform architecture is one system that serves multiple markets (by leveraging some existing assets combined with minor modifications)....Is there a formal modeling language that can simplify communicating this intent? I should note that I haven't read much about software product lines, so I'm not sure if there is actually a standard modeling approach to SPL that i'm not aware of....I'm also interested in knowing if there are special configuration management practices for such systems. thanks,

  • FluentNhibernate dynamic runtime mappings.

    - by Paul Knopf
    I am building a framework where people will be able to save items that the created by inheriting a class of mine. I will be iterating over every type in the appdomain to find classes that I want to map to nhibernate. Every class that I find will be a subclass of the inherited type. I know how to create sub types in FluentNhibernate, but every sub type requires its own ClassMap class. Since I won't know these untill runtime, there is no way I can do that. Is there a way that I can add mappings to fluent nhibernate? Note, I know this is possible without fluent nhibernate using the Cfg class, but I don't want to manage the same code two different ways.

  • Official way to ask jQuery wait for all images to load before executing something

    - by Simon_Weaver
    In jQuery when you do this: $(function() { alert("DOM is loaded, but images not necessarily all loaded"); }); It waits for the DOM to load and executes your code. If all the images are not loaded then it still executes the code. This is obviously what we want if we're initializing any DOM stuff such as showing or hiding elements or attaching events. Let's say though that I want some animation and I don't want it running until all the images are loaded. Is there an official way in jQuery to do this? The best way I have is to use <body onload="finished()">, but I don't really want to do that unless I have to. Note: There is a bug in jQuery 1.3.1 in Internet Explorer which actually does wait for all images to load before executing code inside $function() { }. So if you're using that platform you'll get the behavior I'm looking for instead of the correct behavior described above.

  • Given two lines on a plane, how to find integer points closest to their interseciton?

    - by Lukasz Lew
    I can't solve it: You are given 8 integers: A, B, C representing a line on a plane with equation A*x + B*y = C a, b, c representing another line x, y representing a point on a plane The two lines are not parallel therefore divide plane into 4 pieces. Point (x, y) lies inside of one these pieces. Problem: Write a fast algorithm that will find a point with integer coordinates in the same piece as (x,y) that is closest to the cross point of the two given lines. Note: This is not a homework, this is old Euler-type task that I have absolutely no idea how to approach.

  • Correct way to write /* and */

    - by billpg
    Hi everyone. I'd like to know, please, the correct way to write the symbols that the C family of languages use to begin and end comments. Before you all respond "a slash followed by an asterisk", I mean what's the correct way to write them on paper. (IE, How many points should the asterisk have? What angle should the slash be? etc) Everything I need so I can sit down and draw correct comment start and end symbols. Please note, I'm looking for the correct standard way. If there is no industry standard, please respond with "there is no standard" and I will accept that answer.

  • Why do C++ streams use char instead of unsigned char?

    - by Johannes Schaub - litb
    I've always wondered why the C++ Standard library has instantiated basic_[io]stream and all its variants using the char type instead of the unsigned char type. char means (depending on whether it is signed or not) you can have overflow and underflow for operations like get(), which will lead to implementation-defined value of the variables involved. Another example is when you want to output a byte, unformatted, to an ostream using its put function. Any ideas? Note: I'm still not really convinced. So if you know the definitive answer, you can still post it indeed.
