  • Are there any widespread, modern Java coding conventions?

    - by brianegge
    Sun's "Code Conventions for the Java Programming Language" was last updated April 1999. Ten years later a lot has changed in the language, as well as general usage patterns. Are there more up to date, widely adopted standards? Most guidelines omit specifying file encoding and line endings. Sun recommends mixed tabs and spaces. The Eclipse IDE defaults to Eclipse's standard, which is tabs only. The Maven style guide is spaces only. Many style guides, such as JBoss, follow Sun's guidelines, but prefer K&R braces instead of OTBS. Each Apache project has it's own style guide, with slight differences between each one.

  • How to setup fluent nhibernate to work with Fitnesse

    - by Toran Billups
    I'm currently using fluent nhibernate and can't seem to get the configuration to work when using Fitnesse. For starters I have a FitServer.exe.config that looks like the below <?xml version="1.0" encoding="utf-8" ?> <configuration> <appSettings file='C:\projectpath\web.config' /> </configuration> Then inside my web.config I have a connection string defined But will Fitnesse work when I use the following config? (using the ConnectionString config) private static ISessionFactory CreateSessionFactory() { var cfg = Fluently.Configure() .Database(MsSqlConfiguration.MsSql2005.ConnectionString(c => c.FromConnectionStringWithKey("Local"))) .Mappings(m => m.FluentMappings.AddFromAssembly(Assembly.GetExecutingAssembly())) .ExposeConfiguration(x => x.SetProperty("current_session_context_class", "thread")); return cfg.BuildSessionFactory(); }

  • Python.expat can't parse XML file with bad symbols. How to go around?

    - by culebrón
    I'm trying to parse an XML file with expat, and here's the line where I get bad token exception: <tag k="name" v="???????????????????????????????????????????????????????????????????" /> xml.parsers.expat.ExpatError: not well-formed (invalid token): line 610127, column 37 The symbols in hex look like: \xd1? Seems like someone wrote this string (Russian alfabet) hitting backspace a few times. I set parser.returns_unicode = True, but this didn't help. The 1st line is <?xml version="1.0" encoding="UTF-8"?>. I work with a bz2 file. (bz2.BZ2File) How can I parse the file?

  • NSMutableUrlRequest eats plus signs

    - by Mike
    I create NSMutableUrlRequest for sending data to server, add all necessary fields to it and then add the string for sending like this: [theRequest setHTTPBody:[postString dataUsingEncoding: NSUTF8StringEncoding]]; postString is a usual NSString. The problem is, when I receive this request at the server, all the plus (+) signs disappear from the http body. So if I had "abcde+fghj" on iPhone, I get "abcde fghj" on the server". Can this be some encoding problem from using dataUsingEncoding: NSUTF8StringEncoding? Or some NSMutableUrlRequest stripping feature? What can I do to make it stop stripping plus signs? I need to receive UTF8 strings at the server side.

  • How to force PyYAML to load strings as unicode objects?

    - by Petr Viktorin
    The PyYAML package loads unmarked strings as either unicode or str objects, depending on their content. I would like to use unicode objects throughout my program (and, unfortunately, can't switch to Python 3 just yet). Is there an easy way to force PyYAML to always strings load unicode objects? I do not want to clutter my YAML with !!python/unicode tags. # Encoding: UTF-8 import yaml menu= u"""--- - spam - eggs - bacon - crème brûlée - spam """ print yaml.load(menu) Output: ['spam', 'eggs', 'bacon', u'cr\xe8me br\xfbl\xe9e', 'spam'] I would like: [u'spam', u'eggs', u'bacon', u'cr\xe8me br\xfbl\xe9e', u'spam']

  • Programmatically enable tracing?

    Is there a way to programmatically enable diagnostic tracing for a WSE web service client? This is how it should be configured using an app.config file: <?xml version="1.0" encoding="utf-8"?> <configuration> <configSections> <section name="microsoft.web.services3" type="Microsoft.Web.Services3.Configuration.WebServicesConfiguration, Microsoft.Web.Services3, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" /> </configSections> <microsoft.web.services3> <diagnostics> <trace enabled="true" input="InputTrace.webinfo" output="OutputTrace.webinfo" /> </diagnostics> </microsoft.web.services3> </configuration> I would like to do this from code.

  • Text editor with "forensic" capabilities?

    - by Timo
    This is what happened: I wrote a perl script using TextWrangler and managed to change the encoding to UTF8 BOM, which inserts te BOM marker at the start of the file. Perl promptly misses the #! and mayhem ensues. It then takes me the better part of an afternoon to figure this out since most text editors do not show the BOM marker even with various "show invisibles" options turned on. Now, I've learned my lesson, I should have used less immediately, etc. etc.. What I'm wondering though is whether there is a text editor out there that lets you see every single byte of the file, even if they are "invisible"?

  • Xerces SAX parser ignore the xmlxs:xsi attribute as an attribute of an element

    - by user603301
    Hi, Using Xerces SAX parser I try to retrieve all elements and their attributes of this XML file: -------------- Begin XML file to parse ---------------- <?xml version="1.0" encoding="UTF-8"?> <invoice xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="my.xsd"> <parties> (...) -------------- End XML file to parse ---------------- When getting the attributes for the element 'invoice', Xerces++ does not insert the 'xmlns:xsi' attribute in the list of 'Attributes' for the element 'invoice'. However, the attribute 'xsi:noNamespaceSchemaLocation' is inserted in the list. Why? Is there a specific reason from an XML standard point of view ? Is there a way to configure Xerces++ SAX parser so that it inserts this attribute as well? (The documentation on setting the parser properties does not tell how). Thanks for your help.

  • Converting 24BPP to 4BPP with GDI+ in VB.NET

    - by Chris
    My VB.NET program currently takes a 4BPP TIFF as an Bitmap, converts it to a Graphic, adds some text strings and then saves it out again as a TIFF file. The output Bitmap.Save() TIFF file by default seems to be 24BPP (regardless of the input) and is a lot larger than the original TIFF. Is it possible to keep the same 4BPP palette encoding as the input for the output and if not, how can I convert my Bitmap PixelFormat from 24BPP to 4BPP Indexed. I've seen an example for converting 24 BPP to 1 BPP at http://www.bobpowell.net/onebit.htm using BitmapData.Lockbits() but cannot figure out how to do it for 4BPP. Many thanks Chris

  • Confused about Huffman Trees

    - by ShrimpCrackers
    A quick tutorial on generating a huffman tree Confused about Huffman Trees. Near the end of that link above, it shows the tree with 2 elements left, and then the completed tree. I'm confused about the way that it is branched. Is there a specific way a huffman tree needs to be branched? For example, 57:* with its right child 35:* is branched off to the right. Could it have been 35 branched to the left with 22 branched to the right? Also, why wasn't 22:* paired up with 15:4 - it just paired with 20:5 to create a new tree. From initial obersvations it seems the tree does not need to be balanced or have any specific order other than that the frequencies of a leaf add up to the value of the parent node. Could two people creating a huffman tree with the same data end up with different encoding values?

  • CodeIgniter Project Giving 303/Compression Error

    - by Tim Lytle
    Trying to setup a CodeIgniter based project for local development (LAMP stack), and once all the config file were updated (meaning I successfully had meaningful bootstrap errors for CodeIgniter), I get this error in my browsers: Chrome Error 330 (net::ERR_CONTENT_DECODING_FAILED): Unknown error. Firefox Content Encoding Error: The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression. Just using wget to fetch the file works fine, no errors and I get the content I'm expecting. Not sure if this is something with CI and the Server, or just something weird with the project. Has anyone seen this before?

  • Emulating HTTP POST via httpclient 3.x for multi options

    - by Frankie Ribery
    I want to emulate a HTTP POST using application/x-www-form-urlencoded encoding to send a option group that allows multiple selections. <select name="groups" multiple="multiple" size="4"> <option value="2">Administration</option> <option value="1">General</option> </select> Does adding 2 NameValuePairs (NVP) with the same name work ? My serverside log shows that only the first NVP was received. e.g PostMethod method = ...; NameValuePair[] nvpairs = { new NameValuePair( "groups", "2" ); new NameValuePair( "groups", "1" ); }; method.addParameter( nvpairs ); Only the groups=1 parameter was received.

  • java xml pretty printing - preserve empty elements and white pace

    - by javamonkey79
    Basically, I am looking for a java library that will take this: <foo><bar> </bar><baz>yadda</baz></foo> And pretty print it to this: <?xml version="1.0" encoding="UTF-8"?> <foo> <bar> </bar> <baz>yadda</baz> </foo> e.g. preserving whitespace AND blank elements The closest I have got was with dom4j like so: OutputFormat format = OutputFormat.createPrettyPrint(); format.setTrimText( false ); However, this does not honor the whitespace unless the element contains other character data. I'm not opposed to writing something on my own, but I would think this has already been done, why reinvent the wheel?

  • Protocol Buffers In C#: How Are Boxed Value Types Handled

    - by Greg Dean
    In the following examples: public class RowData { public object[] Values; } public class FieldData { public object Value; } I am curious as how either protobuf-net or dotnet-protobufs would handle such classes. I am more familiar with protobuf-net, so what I actually have is: [ProtoContract] public class RowData { [ProtoMember(1)] public object[] Values; } [ProtoContract] public class FieldData { [ProtoMember(1)] public object Value; } However I get an error saying "No suitable Default Object encoding found". Is there an easy way to treat these classes, that I am just not aware of? To elaborate more on the use case: This is a scaled down version of a data class used in remoting. So essentially it looks like this: FieldData data = new FieldData(); data.Value = 8; remoteObject.DoSomething(data); Note: I've omitted the ISerializable implementation for simplicity, but it is as you'd expect.
