• Joining and compressing all javascript files together - good idea?

  - by Tomáš Zato

  Curently, I avoid loading any unnecesary scripts on individual pages of my site. I have a class that remembers all javascript files that were requested during PHP processing and adds them to HTML. I was just thinking that I could merge the current set of files, save the result in special directory and let the browser download just one, big file. Since the number of possible combinations is not very high, I would end up with about 10 combined files for different pages. I've never seen that on any site. What are the reasons not to do it? I need very fast page load.

• Can't right click, copy or move files to Desktop???

  - by user1698774

  I am on Ubuntu 12.04 running gnome shell 3. Everything worked fine until I updated just a few hours ago using the update package. First my default shortcuts stopped working, fixed it by creating custom ones. Now while on the desktop I can't right-click, move files to it or see the files that were there previously. However, in terminal I can navigate fine to Desktop and my files are there, except not visually on the desktop. Permissions are all set correctly. Please help. Thank you.

• Does GPG allow encryption of multiple files using a wild card like *filename*? [on hold]

  - by user47427

  I am trying to automate the encryption of files on a windows server using a .bat file I created. As long as the filename is hardcoded in the .bat file this works. I want to encrypt numerous files using this .bat file but files are not encrypted when I use wildcards in the filename like filename.txt. I've been trying various version of the following command at the DOS prompt to no avail. All attempts have returned syntax for usage. C:\gpg -v --batch -- yes --always-trust -e -r <encryption-key> *part-of-the-file-name* usage: gpg [options] --encrypt [filename] I received the same usage message with this command: C:\gpg -v --batch -- yes --always-trust -e -r --encrypt part-of-the-file-name I tried without the -v and some of the other options and I still received the same message. I have spent hours today searching the internet for an answer and I can't find one anywhere? Please help.

• Had almost 300 GB worth of files with random names on my computer, and now they are gone. Any idea what they were and where they went?

  - by John

  A couple of days ago I noticed I had a folder on my computer with more than 15 files in it. All the files were the exact same size (215 MB). They all had different names (just a bunch of random characters like Abe327(/-38s etc. I wasn't sure what they were so I decided to try to delete them. But then I noticed they disappeared from the D drive. Then the next day I noticed a new folder, with similar names and file sizes showed up on my C drive. The timestamps on the first set of files was almost all from a few months ago. Like the timestamps were saying 3:52 AM, 403 AM, etc. all from the same date. Then the set of files on the C drive that just appeared had yesterday's date on them. But similarly, all the files had timestamps within a 24 hour period. Like they had all just been created. Now this morning, all of those files are gone, and I didn't delete them. There are now no files like this in either drive. Any idea what these files were? Why were they so large, and why are they switching drives? Why did they disappear completely now, after the initial files were there for a few months.

• MonoTouch: using embedded resx files on iPhone build

  - by bright

  I'm able to load and access resx files in Simulator builds of my iPhone app built using MonoTouch. The resx file entry in the csproj file looks like: <ItemGroup> <EmbeddedResource Include="MapMenu\Resources\MapMenu.resx"> <Generator>ResXFileCodeGenerator</Generator> <LastGenOutput>MapMenu.Designer.cs</LastGenOutput> </EmbeddedResource> </ItemGroup> The .resx file itself has an entry like this: <data name="Main_Menu" type="System.Resources.ResXFileRef, System.Windows.Forms"> <value>Main Menu.mm;System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089;Windows-1252</value> </data> and the generated MapMenu.Designer.cs file has this: internal static string Main_Menu { get { return ResourceManager.GetString("Main_Menu", resourceCulture); } } As mentioned above, calling the Main_Menu accessor works fine on the simulator. On the device, however, it produces: <Notice>: Unhandled Exception: System.MissingMethodException: No constructor found for System.Resources.RuntimeResourceSet::.ctor(System.IO.UnmanagedMemoryStream) <Notice>: at System.Activator.CreateInstance (System.Type type, BindingFlags bindingAttr, System.Reflection.Binder binder, System.Object[] args, System.Globalization.CultureInfo culture, System.Object[] activationAttributes) [0x00000] in <filename unknown>:0 <Notice>: at System.Activator.CreateInstance (System.Type type, System.Object[] args, System.Object[] activationAttributes) [0x00000] in <filename unknown>:0 <Notice>: at System.Activator.CreateInstance (System.Type type, System.Object[] args) [0x00000] in <filename unknown>:0 <Notice>: at System.Resources.ResourceManager.InternalGetResourceSet (System.Globalization.CultureInfo culture, Boolean createIfNotExists, Boolean tryParents) [0x00000] in <filename unknown>:0 <Notice>: at System.Resources.ResourceManager.GetString (System.String name, System.Globalization.CultureInfo culture) [0x00000] in <filename unknown>:0 <Notice>: at MapMenu.Resources.MapMenu.get_Main_Menu () [0x00000] in <filename unknown>:0 Did a few sanity checks, and am wondering at this point if this really is missing functionality in Monotouch. Thanks,

• Possible to use multiple ServiceReference.ClientConfig files?

  - by Maciek

  I'm building a modular Silverlight application, using Prism. In the Shell project, I'm loading 2x modules, each hailing from a separate assembly. For convenience let's call them ModuleA and ModuleB ModuleA makes calls to WebServiceA. A ServiceReference.ClientConfig file is present in ModuleA's assembly. In order for this to work, in the shell project, I've added an "existing item" (path set to the forementioned config file in ModuleA's folder) as a link. The shell launched and the ModuleA made a successful call to the WebServiceA. Currently, I'm working on ModuleB, it also needs to make webservice calls, this time to WebServiceB. The service reference has been added, and a ServiceReference.ClientConfig file has appeared in ModuleB's assembly. I've attempted to add that config file as a link to the shell project as well, but I've failed. Q1 : Is it possible to use multiple ServiceReference.ClientConfig files like this? Q2 : Are there any best-practices for this case? Q3 : Is it possible to rename a *.config or *.ClientConfig file ? How is it done? How do I tell the application what file to use? Edit : Formatting

• Base 128 or 256 Encoding for the Binary Lexical Octet Adhoc Transport Protocol?

  - by Randolpho

  I'm in the process of implementing a network driver for the Binary Lexical Octet Adhoc Transport (BLOAT) protocols in the hopes of replacing the TCP/UDP/IP stack with a much more flexible XML structure. BLOAT is detailed in RFC 3252, so if you're unfamiliar with the protocol I highly recommend you read the entire RFC before providing any comments. Don't worry, it's short and sweet; you might even enjoy it. Anyway, my problem is this: BLOAT requires that the payload be Base64 encoded which doesn't make sense to me. I mean, sure, it's the internet standard for binary payloads, but there are better, more efficient encodings available: Base128 and Base256, for example. That the RFC requires Base64 and doesn't allow for any other payload encoding really bothers me. To that end, I'm considering a small optional change to the protocol. Embrace and extend, right? Anyway, I'd like to modify the payload element to accept an encoding attribute, which can extend the encoding to Base128 or Base256, or even to other encodings I can't conceive of at the moment. If the encoding attribute isn't present, Base64 would be assumed. So my question is this: should I? I mean, BLOAT is an accepted standard, even if it isn't exactly omnipresent. If I make this change, will there be compatibility issues? I don't foresee any, but perhaps you, oh great Stack Overflow Community, can? If I do implement this change, should I contact the original RFC author? Should I offer a supplemental RFC?

• Typedef and Struct in C and H files

  - by Leif Andersen

  I've been using the following code to create various struct, but only give people outside of the C file a pointer to it. (Yes, I know that they could potentially mess around with it, so it's not entirely like the private keyword in Java, but that's okay with me). Anyway, I've been using the following code, and I looked at it today, and I'm really surprised that it's actually working, can anyone explain why this is? In my C file, I create my struct, but don't give it a tag in the typedef namespace: struct LABall { int x; int y; int radius; Vector velocity; }; And in the H file, I put this: typedef struct LABall* LABall; I am obviously using #import "LABall.h" in the c file, but I am NOT using #import "LABall.c" in the header file, as that would defeat the whole purpose of a separate header file. So, why am I able to create a pointer to the LABall* struct in the H file when I haven't actually included it? Does it have something to do with the struct namespace working accross files, even when one file is in no way linked to another? Thank you.

• PDF files created on iPad dont display correctly on Windows

  - by user286028

  My iPhone app creates PDF files (in Arial font). The plain iPhone 3.1.x version works great (other than the known issue that PDFs created on the iPhone cant be viewed correctly in Google Docs or the BlackBerry). As I am updating my project for OS 3.2 and the iPad, it works just the same, and the PDFs still look great on the iPhone, iPad and MacOS (Preview app). But now on Windows (Vista), Acrobat 9.3.1 says "Cannot extract the embedded font 'XYZABC+ArialMT'. Some characters may not display or print correctly". And in fact Acrobat then uses some generic font instead of Arial (or whatever other font I try). Quartz 3.2 seems to generate these "random" embedded font names each time it creates a PDF (the XYZABC changes around each time). I can't tell whether the problem is just the somewhat strange "temporary" embedded font name with the plus sign, or the way Quartz 3.2 is embedding fonts. I have tried my existing code (using CGPDFContext* funtions), and also the newly supported UIGraphics* functions, with the same results. Has anyone else tried creating PDFs on the iPad yet and gotten them to display correctly on Windows?

• AVAudioPlayer only initializes with some files

  - by Brendan

  Hi everyone, I'm having trouble playing some files with AVAudioPlayer. When I try to play a certain m4a, it works fine. It also works with an mp3 that I try. However it fails on one particular mp3 every time (15 Step, by Radiohead), regardless of the order in which I try to play them. The audio just does not play, though the view loading and everything that happens concurrently happens correctly. The code is below. I get the "Player loaded." log output on the other two songs, but not on 15 Step. I know the file path is correct (I have it log outputted earlier in the app, and it is correct). Any ideas? NSData *musicData = [NSData dataWithContentsOfURL:[[NSURL alloc] initFileURLWithPath:[[NSBundle mainBundle] pathForResource:[song filename] ofType:nil]]]; NSLog([[NSBundle mainBundle] pathForResource:[song filename] ofType:nil]); if(musicData) { NSLog(@"File found."); } self.songView.player = [[AVAudioPlayer alloc] initWithData:musicData error:nil]; if(self.songView.player) { NSLog(@"Player loaded."); } [self.songView.player play]; NSLog(@"You should be hearing something now."); Thanks, Brendan

• XML validation error when using multiple schema files/namespaces

  - by user129609

  Hi, I've been reading a ton about xml and learning a lot but I am stuck on one error. I have a schema defined in multiple files and I can't get it to work. Here is an example ================================== libraryBooks.xsd <?xml version="1.0" encoding="utf-8"?> <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="urn:MyNamespace" targetNamespace="urn:MyNamespace" elementFormDefault="qualified" > <xsd:element name="libraryBooks" type="libraryBooksType"/> <xsd:complexType name="libraryBooksType"> <xsd:sequence> <xsd:any minOccurs="0"/> </xsd:sequence> <xsd:attribute name="name" type="xsd:string"/> </xsd:complexType> </xsd:schema> ================================== book.xsd <?xml version="1.0" encoding="utf-8"?> <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="urn:MyNamespace2" targetNamespace="urn:MyNamespace2" elementFormDefault="qualified" > <xsd:element name="book" type="booksType"/> <xsd:complexType name="bookType"> <xsd:attribute name="title" type="xsd:string"/> </xsd:complexType> </xsd:schema> ================================== myXml.xml <?xml version="1.0" encoding="utf-8" ?> <libraryBooks xmlns="urn:MyNamespace" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="urn:MyNamespace file:///C:/libraryBooks.xsd" name="CentralLibrary"> <mn2:book xmlns:mn2="file:///C:/book.xsd" title="How to make xml work the way I want"> </mn2:book> </libraryBooks> So the error I get would be "The 'file:///C:/book.xsd:book' element is not found". Any ideas? I'm almost certain it is something simple

• UTF-8 BOM signature in PHP files

  - by skidding

  I was writing some commented PHP classes and I stumbled upon a problem. My name (for the @author tag) ends up with a ? (which is a UTF-8 character, ...and a strange name, I know). Even though I save the file as UTF-8, some friends reported that they see that character totally messed up (È™). This problem goes away by adding the BOM signature. But that thing troubles me a bit, since I don't know that much about it, except from what I saw on Wikipedia and on some other similar questions here on SO. I know that it adds some things at the beginning of the file, and from what I understood it's not that bad, but I'm concerned because the only problematic scenarios I read about involved PHP files. And since I'm writing PHP classes to share them, being 100% compatible is more important than having my name in the comments. But I'm trying to understand the implications, should I use it without worrying? or are there cases when it might cause damage? When? Thanks!

• Basic Steps in reading Excel files into matlab

Error using ==> xlsread at 219 XLSREAD unable to open file C:\Users\Lincoln Wachn\Google Drive\Summer time\Book1. File C:\Users\Lincoln Wachn\Google Drive\Summer time\Book1.xls not found. This is the error that I have received when I try to read a simple Excel file into MATLAB. This is a snapshot of the spreadsheet I would like to load in. Could guide me the basic know-how to extract these data? I have looked through the other questions pertaining to reading Excel files into MATLAB, but I am still very confused. I ultimately wish to extract the file below for my project using the same method. The second image shows the data I have to extract which I could not do. Its file type seems to be different, it is comma separated values file which is not xls. Hence, I am also confuse about whether different file type prevents extraction of data. Thanks you for helping(:

• nHibernate Domain Model and Mapping Files in Separate Projects

  - by Blake Blackwell

  Is there a way to separate out the domain objects and mapping files into two separate projects? I would like to create one project called MyCompany.MyProduct.Core that contains my domain model, and another project that is called MyCompany.MYProduct.Data.Oracle that contains my Oracle data mappings. However, when I try to unit test this I get the following error message: Named query 'GetClients' not found. Here is my mapping file: <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="MyCompany.MyProduct.Core" namespace="MyCompany.MyProduct.Core" > <class name="MyCompany.MyProduct.Core.Client" table="MY_CLIENT" lazy="false"> <id name="ClientId" column="ClientId"></id> <property name="ClientName" column="ClientName" /> <loader query-ref="GetClients"/> </class> <sql-query name="GetClients" callable="true"> <return class="Client" /> call procedure MyPackage.GetClients(:int_SummitGroupId) </sql-query> </hibernate-mapping> Here is my unit test: try { var cfg = new Configuration(); cfg.Configure(); cfg.AddAssembly( typeof( Client ).Assembly ); ISessionFactory sessionFactory = cfg.BuildSessionFactory(); IStatelessSession session = sessionFactory.OpenStatelessSession(); IQuery query = session.GetNamedQuery( "GetClients" ); query.SetParameter( "int_SummitGroupId", 3173 ); IList<Client> clients = query.List<Client>(); Assert.AreNotEqual( 0, clients.Count ); } catch( Exception ex ) { throw ex; } I think I may be improperly referencing the assembly, because if I do put the domain model object in the MyComapny.MyProduct.Data.Oracle class it works. Only when I separate out in to two projects do I run into this problem.

• Multimedia files written over WAN are getting truncated

  - by Dean

  I use the windows Multimedia API to create .wav files. 1. Open file with mmsioOpen 2. Creates WAVE,frm and data chunks using mmioCreateChunk 3. Write audio data using mmioWrite 4. Ascend out of the chunks using mmioAscend 5. Close file using mmioClose The file is being written into a temporary location, so after it has been closed it gets copied to another location using the CopyFile. This program is written in C++ and works great until the file it is writing resides over a WAN in a different city or country. The end result is a wav file that should be 20-30 seconds long ends up being 4 secodns long. It is always the last bit that is missing, so when you play it back it just stops before then of the recording. I initially thought that maybe I was copying the file too soon so as a test I put in a pause of 30 seconds after closing the file using Sleep(30000), but this made no difference to either it being truncated or by how much. I have modified the program to write to a file in parrallel using CreateFile and WriteFile, and the result is the same, so it is not an issue specifically with the mmio API's. Does anyone have any ideas why this is happening and if there is a work-around to it? I suspect that I may end up having the temporary location on the local drive, but this is quite a big change to the application as well as existing deployments. thanks for everyones time Dean

• HttpHandler and XML files

  - by Frank

  Hello, I would like to intercept any request made to the server for XML files. I thought that it might be possible with an HttpHandler. It's coded and it works... on localhost only (?!?!). So, why is it working on localhost only? Here is my web.config <?xml version="1.0" encoding="utf-8"?> <configuration> <system.web> <httpHandlers> <add verb="*" path="*.xml" type="FooBar.XmlHandler, FooBar" /> </httpHandlers> </system.web> </configuration> Here is my C# : namespace FooBar { public class XmlHandler : IHttpHandler { public bool IsReusable { get { return false; } } public void ProcessRequest(HttpContext context) { HttpResponse Response = context.Response; Response.Write(xmlString); } } } As you might have seen, I'm writing the xmlString directly in the response, it's only temporary because I'm still wondering how I could give the filename instead (that's the second question ;) ) What is supposed to be written in the response is only the xml filename that will be retrieved by a flash app. Thanks Edit : When calling the page from another computer it looks like it's not getting to the HttpHandler. However, the mapping for IIS have been done correctly.

• Best way to "un-promote" files in Accurev?

  - by Luke Rinard

  My company uses Accurev for source control, and for all its benefits, there's one simple action that I just can't figure out how to accomplish. Often we have someone accidentally push a file up too far in our stream structure -- from the "Development" stream to the "Release" stream, for example. What is the best way to "un-promote" this file? That is to say, to get the old version of the file back into the "Release" stream, and keep the new version of the file in the "Development" stream, where it belongs? Just doing a "Revert to Backed" or other Revert action on the file in the Release stream will either cause an old version of the file to propagate down into Development, or will make the file disappear entirely. In the above case, the developer will have to jump through hoops with setting basis times on streams, or use the command line tool to do a checkout of an old transaction, to get the file back. Sometimes the people in question are non-technical, so this is not a good solution. I have also considered moving the files to a "higher ground" stream, reverting, and then cross-promoting them to the lower stream again. This seems really kludgy. It seems like Accurev is obscure enough that Google is no help, so I turn to the good folks of StackOverflow for help -- has anybody figured out the "Accurevy" way to accomplish this?

• MSBuild - Writing Escape Characters to Files

  - by Richm7

  I've got a very similar scenario to the one described in this post. It describes how to load the contents of a file that contains properties & items, making sure they're resolved as part of the process. I'm doing the same thing except writing the contents away to another text file (generally .ini file). In short I'd start by importing a project / propertygroup which contains this text: ; ----------- [heading] setting1=$(FirstValue) setting2=$(SecondValue) setting3=list;of;values;delimited;by;semicolons setting4=bla bla bla ; ----------- & hopefully write it away to a new .ini file containing the following: ; ----------- [heading] setting1=value resolved by msbuild setting2=another value resolved by msbuild setting3=list;of;values;delimited;by;semicolons setting4=bla bla bla ; ----------- Only problem is that some files will contain semicolons. I can live without comments, but they're also used as part of values e.g. in lists. This is the result of using the WriteLinesToFile task. The semicolons are treated as escape characters & result in new lines, so the value of 'setting3' in the above example would be split over 6 lines. Is there a way around this without implementing my own task? Thanks in advance for the help!

• What is .tpl files? php, web design

  - by Dan

  Hi guys! A man wants me to redesign a site run in PHP (VideoCMS). But when I asked him to send me the source he has given me *.tpl files instead of *.php. There is some code inside them: {include file='header.tpl' p="article"} <br /> <table width="886" border="0" cellspacing="0" cellpadding="0"> <tr> <td width="150" valign="top"> <div id="reg_box"> <h3 class="captions">{$lang.articles}</h3> <div id="list_cats"> <ul> {$article_categories} </ul> </div> </div> <br /> <div id="reg_box"> <h3 class="captions">{$lang.members}</h3> {if $logged_in == '1'} {include file='loggedin_body.tpl'} {else} {include file='login_body.tpl'} {/if} or {include file='header.tpl' p="index"} {php} $_SESSION['isFair'] = "Yes"; {/php} Question: what's the interpreter of the code?

• VS 2008 does not understand .resource files

  - by Dmitry

  I'm trying to add globalization support to my C# application. According to MSDN, there should be one embedded resource file for neutral culture and satellite DLLs with resource files for other cultures. I've created 2 satellite DLLs without any problems and got my app to automatically load right one using ResourceManager. But I can't embed default neutral culture resource file into my executable. When I remove all satellite DLLs or set culture to some culture I don't have satellite DLL for, I get exception "Could not find any resources appropriate for the specified culture or the neutral culture." when application attempts to create ResourceManager. It looks like VS 2008 does not include my .resource file into main assembly. I've tried different ways to get resource file embedded: compiling it by resgen.exe from text file and adding it to the project; changing its name to add second .resources extension; creating .resx file with same name; etc. And I still don't see the way to get resource file embedded and used by ResourceManager - I'm having same exception. What is the right way to add default neutral culture resource file to application in VS 2008 ?

• Simple, fast SQL queries for flat files.

  - by plinehan

  Does anyone know of any tools to provide simple, fast queries of flat files using a SQL-like declarative query language? I'd rather not pay the overhead of loading the file into a DB since the input data is typically thrown out almost immediately after the query is run. Consider the data file, "animals.txt": dog 15 cat 20 dog 10 cat 30 dog 5 cat 40 Suppose I want to extract the highest value for each unique animal. I would like to write something like: cat animals.txt | foo "select $1, max(convert($2 using decimal)) group by $1" I can get nearly the same result using sort: cat animals.txt | sort -t " " -k1,1 -k2,2nr And I can always drop into awk from there, but this all feels a bit awkward (couldn't resist) when a SQL-like language would seem to solve the problem so cleanly. I've considered writing a wrapper for SQLite that would automatically create a table based on the input data, and I've looked into using Hive in single-processor mode, but I can't help but feel this problem has been solved before. Am I missing something? Is this functionality already implemented by another standard tool? Halp!

• Retrieving many huge sized EPS files and converting them to JPEG in ASP.NET application

  - by Ashish Gupta

  I have many (600) EPS files(300 KB - 1 MB) in database. In my ASP.NET application (using ASP.NET 4.0) I need to retrieve them one by one and call a web service which would convert the content to the JPEG file and update the database (JPEGContent column with the JPEG content). However, retrieving the content for 600 of them itself takes too long from the SQL management studio itself (takes 5 minutes for 10 EPS contents). So I have two issues:- 1) How to get the EPS content ( unfortunately, selecting certain number of content is not an option :-( ):- Approach 1:- foreach(var DataRow in DataTable.Rows) { // get the Id and byte[] of EPS // Call the web method to convert EPS content to JPEG which would also update the database. } or foreach(var DataRow in DataTable.Rows) { // get only the Id of EPS // Hit database to get the content of EPS // Call the web method to convert EPS content to JPEG which would also update the database. } or Any other approach? 2) Converting EPS to JPEG using a web method for 600 contents. Ofcourse, each call would be a long running operation. Would task parellel library (TPL) be a better way to achieve this? Also, is doing the entire thing in a SQL CLR function a good idea?

  Hello all, I've got a CSV file with a format that looks like this: "FieldName1", "FieldName2", "FieldName3", "FieldName4" "04/13/2010 14:45:07.008", "7.59484916392", "10", "6.552373" "04/13/2010 14:45:22.010", "6.55478493312", "9", "3.5378543" ... Note that there are double quote characters at the start and end of each line in the CSV file, and the "," string is used to delimit fields within each line. When I try to read this into numpy via: import numpy as np data = np.genfromtxt(csvfile, dtype=None, delimiter=',', names=True) all the data gets read in as string values, surrounded by double-quote characters. Not unreasonable, but not much use to me as I then have to go back and convert every column to its correct type When I use delimiter='","' instead, everything works as I'd like, except for the 1st and last fields. As the start of line and end of line characters are a single double-quote character, this isn't seen as a valid delimiter for the 1st and last fields, so they get read in as e.g. "04/13/2010 14:45:07.008 and 6.552373" - note the leading and trailing double-quote characters respectively. Because of these redundant characters, numpy assumes the 1st and last fields are both String types; I don't want that to be the case Is there a way of instructing numpy to read in files formatted in this fashion as I'd like, without having to go back and "fix" the structure of the numpy array after the initial read?
