  • How can I make Google show unit conversions by default?

    - by bUbUKid
    When I search for "4 inches in g" on my Windows Firefox I immediately get a unit conversion done by Google that shows up before the actual search results. On my Ubuntu 12.04 system this does not work though. I tried Firefox and Chromium and have no script blockers installed. I also switched off AdBlock Plus for testing but to no avail. I realize that this is not really Ubuntu doing something wrong but: Are there any settings I can modify to make Google show these results? I use them quite frequently and I believe (though I cannot test it anymore) that this used to work on my last Ubuntu System. Maybe there are some script sources that Ubuntu has disabled by default or something like that?

  • Is doing AB Tests using site redirection a bad practice?

    - by user40358
    I'm developing hotels websites here in Brazil. When the site is done, we do an AB test with the old version to measure conversion and show to the hotel owner how good our site is. Due to the fact that I cannot put the old site inside the new one as a subresource (newone.com/old), currently I'm doing those AB test as follows: 1) I create 2 Google Analytics accounts, one for each site (old and new); 2) I put the GA tags in the old website pages (changing its possibly existent GA ID to the just created one); 3) I put an Javascript code that redirects the user to the old website (in a different URL and different domain) with 50% of probability. So I compare all the metrics, events and goals between those two GA accounts. How bad is it? How Google can interpretate the fact of being, sometimes redirected, sometimes don't? The experiment usually runs for 2 weeks. Is there any other alternative for doing this in a better way?

  • Error creating an .img file from an .ISO (MD5 verified)

    - by Rob
    I was following the instructions on this website to create a bootable USB flash drive on a Mac: http://www.ubuntu.com/download/help/create-a-usb-stick-on-mac-osx The instruction: hdiutil convert -format UDRW -o ~/path/to/target.img ~/path/to/ubuntu.iso does not create a valid file that the disk utility can copy to the USB drive, making installation on a USB drive useless. I've been repeating these instructions for days with no luck. The only thing that does not work is the .ISO to .IMG conversion. Is there a way to download Ubuntu 12.04 LTS 64-but Desktop in a .IMG file already? Unfortunately, my install notebook does not have an optical drive so USB is the only way. Thanks for your help!

  • Help with tracking sub domain

    - by roobus
    I currently have my app's marketing/external website on the root level, e.g. http://example.com My web app itself is hosted at: http://app.example.com What's the best strategy to set-up Google Analytics tracking for both of them? Should I create a separate web property? Also, what's the difference between creating a new web property and a new profile? UPDATE: I would want to be able to track conversion from a page on the root domain to a sign-up page on the app sub-domain.

  • Has anyone used Genetify for A/B testing

    - by Joshak
    I'm working on a small project that will likely run on Wordpress, I always like to run some split testing to improve conversion rates for various goals. Typically if its a small site that I either don't have a budget for or want to keep it as inexpensive as possible I use Google Website Optimizer if I do have a budget I go with Visual Website Optimizer both are great and affordable, but for fun I was checking out alternatives and found Genetify which is an open source project and has some neat features. In searching around I don't see many people talking about it and wondered if anyone here has used it. If so what do you think about it?

  • What is the worst programming language you ever worked with? [closed]

    - by Ludwig Weinzierl
    If you have an interesting story to share, please post an answer, but do not abuse this question for bashing a language. We are programmers, and our primary tool is the programming language we use. While there is a lot of discussion about the best one, I'd like to hear your stories about the worst programming languages you ever worked with and I'd like to know exactly what annoyed you. I'd like to collect this stories partly to avoid common pitfalls while designing a language (especially a DSL) and partly to avoid quirky languages in the future in general. This question is not subjective. If a language supports only single character identifiers (see my own answer) this is bad in a non-debatable way. EDIT Some people have raised concerns that this question attracts trolls. Wading through all your answers made one thing clear. The large majority of answers is appropriate, useful and well written. UPDATE 2009-07-01 19:15 GMT The language overview is now complete, covering 103 different languages from 102 answers. I decided to be lax about what counts as a programming language and included anything reasonable. Thank you David for your comments on this. Here are all programming languages covered so far (alphabetical order, linked with answer, new entries in bold): ABAP, all 20th century languages, all drag and drop languages, all proprietary languages, APF, APL (1), AS400, Authorware, Autohotkey, BancaStar, BASIC, Bourne Shell, Brainfuck, C++, Centura Team Developer, Cobol (1), Cold Fusion, Coldfusion, CRM114, Crystal Syntax, CSS, Dataflex 2.3, DB/c DX, dbase II, DCL, Delphi IDE, Doors DXL, DOS batch (1), Excel Macro language, FileMaker, FOCUS, Forth, FORTRAN, FORTRAN 77, HTML, Illustra web blade, Informix 4th Generation Language, Informix Universal Server web blade, INTERCAL, Java, JavaScript (1), JCL (1), karol, LabTalk, Labview, Lingo, LISP, Logo, LOLCODE, LotusScript, m4, Magic II, Makefiles, MapBasic, MaxScript, Meditech Magic, MEL, mIRC Script, MS Access, MUMPS, Oberon, object extensions to C, Objective-C, OPS5, Oz, Perl (1), PHP, PL/SQL, PowerDynamo, PROGRESS 4GL, prova, PS-FOCUS, Python, Regular Expressions, RPG, RPG II, Scheme, ScriptMaker, sendmail.conf, Smalltalk, Smalltalk , SNOBOL, SpeedScript, Sybase PowerBuilder, Symbian C++, System RPL, TCL, TECO, The Visual Software Environment, Tiny praat, TransCAD, troff, uBasic, VB6 (1), VBScript (1), VDF4, Vimscript, Visual Basic (1), Visual C++, Visual Foxpro, VSE, Webspeed, XSLT The answers covering 80386 assembler, VB6 and VBScript have been removed.

  • How to read XML using XPath in Java

    - by kaibuki
    Hi guys, I want to read XML data using XPath in Java, so for the information I have gathered I am not able to parse XML according to my requirement. here is what I want to do: Get XML file from online via its URL, then use XPath to parse it, I want to create two methods in it. One is in which I enter a specific node attribute id, and I get all the child nodes as result, and second is suppose I just want to get a specific child node value only <?xml version="1.0"?><howto> <topic name="Java"> <url>http://www.rgagnonjavahowto.htm</url> <car>taxi</car> </topic> <topic ame="PowerBuilder"> <url>http://www.rgagnon/pbhowto.htm</url> <url>http://www.rgagnon/pbhowtonew.htm</url> </topic> <topic name="Javascript"> <url>http://www.rgagnon/jshowto.htm</url> </topic> <topic name="VBScript"> <url>http://www.rgagnon/vbshowto.htm</url> </topic></howto> In above example I want to read all the elements if I search via @name and also one function in which I just want the url from @name 'Javascript' only return one node element. I hope I cleared my question :) Thanks. Kai

  • C# Retrieving Data From XML File

    - by Christopher MacKinnon
    I seem to be having a problem with retrieving XML values with C#, which I know it is due to my very limited knowledge of C# and .XML. I was given the following XML file <PowerBuilderRunTimes> <PowerBuilderRunTime> <Version>12</Version> <Files> <File>EasySoap110.dll</File> <File>exPat110.dll</File> <File>pbacc110.dll</File> </File> </PowerBuilderRunTime> </PowerBuilderRunTimes> I am to process the XML file and make sure that each of the files in the exist in the folder (that's the easy part). It's the processing of the XML file that I have having a hard time with. Here is what I have done thus far: var runtimeXml = File.ReadAllText(string.Format("{0}\\{1}", configPath, Resource.PBRuntimes)); var doc = XDocument.Parse(runtimeXml); var topElement = doc.Element("PowerBuilderRunTimes"); var elements = topElement.Elements("PowerBuilderRunTime"); foreach (XElement section in elements) { //pbVersion is grabbed earlier. It is the version of PowerBuilder if( section.Element("Version").Value.Equals(string.Format("{0}", pbVersion ) ) ) { var files = section.Elements("Files"); var fileList = new List<string>(); foreach (XElement area in files) { fileList.Add(area.Element("File").Value); } } } My issue is that the String List is only ever populated with one value, "EasySoap110.dll", and everything else is ignored. Can someone please help me, as I am at a loss.

  • Help Needed Finding a Programmer

    - by ssean
    Good Morning, I am trying to find a programmer to code a piece of custom software for my business. I plan on using this software to manage my business, and possibly sell it to other companies (in the same industry) at a later date. I've never hired a programmer before, so I'm not sure what to expect or where to begin. I know exactly what features I need, and how I want it laid out, I just need someone who can take my ideas and make it happen. This software will be used to manage customer information, and keep track of orders. What I think I need: * SQL Server or similar database that will be located at our office. * Desktop Application, that connects via LAN to the database server (cannot be browser based) * Multiple User Support (Simultaneous users accesing the system) * Needs to be scalable (currently we have 5 employees, but who knows what the future will bring) * Multi-Platform Support (Windows, Linux) I posted a job offer through elance, which seems to raise more questions than answers. How do I decide what language(s) will work best for my situation? (I have received offers for C#, Eclipse, .NET, Powerbuilder, etc. - I want to make sure that I choose the best one now, so I don't run into problems later) Does the programmer hold any rights to the software? (I plan to offer the software for sale at a later date) Any help or insight would be appreciated, and I'd be happy to clarify anything if it helps. Thanks in advance!

  • C# how to get current encoding type used by C# to write/read configuration for config file?

    - by 5YrsLaterDBA
    I am doing connection string encryption. we use our own encryption key with AES algorithm to do this. during the process, we need to convert string to byte array and then convert byte array back to string. I found the encoding play an important role on those conversions. So I need to know the encoding C# is using to get above conversion right. Any idea how to get current encoding programmably? thanks,

  • How to convert a DataSet object into an ObjectContext (Entity Framework) object on the fly?

    - by Marcel
    Hi all, I have an existing SQL Server database, where I store data from large specific log files (often 100 MB and more), one per database. After some analysis, the database is deleted again. From the database, I have created both a Entity Framework Model and a DataSet Model via the Visual Studio designers. The DataSet is only for bulk importing data with SqlBulkCopy, after a quite complicated parsing process. All queries are then done using the Entity Framework Model, whose CreateQuery Method is exposed via an interface like this public IQueryable<TTarget> GetResults<TTarget>() where TTarget : EntityObject, new() { return this.Context.CreateQuery<TTarget>(typeof(TTarget).Name); } Now, sometimes my files are very small and in such a case I would like to omit the import into the database, but just have a an in-memory representation of the data, accessible as Entities. The idea is to create the DataSet, but instead of bulk importing, to directly transfer it into an ObjectContext which is accessible via the interface. Does this make sense? Now here's what I have done for this conversion so far: I traverse all tables in the DataSet, convert the single rows into entities of the corresponding type and add them to instantiated object of my typed Entity context class, like so MyEntities context = new MyEntities(); //create new in-memory context ///.... //get the item in the navigations table MyDataSet.NavigationResultRow dataRow = ds.NavigationResult.First(); //here, a foreach would be necessary in a true-world scenario NavigationResult entity = new NavigationResult { Direction = dataRow.Direction, ///... NavigationResultID = dataRow.NavigationResultID }; //convert to entities context.AddToNavigationResult(entity); //add to entities ///.... A very tedious work, as I would need to create a converter for each of my entity type and iterate over each table in the DataSet I have. Beware, if I ever change my database model.... Also, I have found out, that I can only instantiate MyEntities, if I provide a valid connection string to a SQL Server database. Since I do not want to actually write to my fully fledged database each time, this hinders my intentions. I intend to have only some in-memory proxy database. Can I do simpler? Is there some automated way of doing such a conversion, like generating an ObjectContext out of a DataSet object? P.S: I have seen a few questions about unit testing that seem somewhat related, but not quite exact.

  • Convert excel document (xls) to a plist

    - by John
    I have a pretty straightforward excel document in which I need to use the data in an iPhone app. The xls document has 6 columns, 200 plus rows. I would like to create a plist from the xls document and other than manual copy/paste, is there a means to convert one to the other? Anyone written a macro on the excel side or a utility (perl, etc) to make such a conversion? Thanks John iPhoneDevTips

  • Is there an algorithm for converting quaternion rotations to Euler angle rotations?

    - by Will Baker
    Is there an existing algorithm for converting a quaternion representation of a rotation to an Euler angle representation? The rotation order for the Euler representation is known and can be any of the six permutations (i.e. xyz, xzy, yxz, yzx, zxy, zyx). I've seen algorithms for a fixed rotation order (usually the NASA heading, bank, roll convention) but not for arbitrary rotation order. Furthermore, because there are multiple Euler angle representations of a single orientation, this result is going to be ambiguous. This is acceptable (because the orientation is still valid, it just may not be the one the user is expecting to see), however it would be even better if there was an algorithm which took rotation limits (i.e. the number of degrees of freedom and the limits on each degree of freedom) into account and yielded the 'most sensible' Euler representation given those constraints. I have a feeling this problem (or something similar) may exist in the IK or rigid body dynamics domains. Solved: I just realised that it might not be clear that I solved this problem by following Ken Shoemake's algorithms from Graphics Gems. I did answer my own question at the time, but it occurs to me it may not be clear that I did so. See the answer, below, for more detail. Just to clarify - I know how to convert from a quaternion to the so-called 'Tait-Bryan' representation - what I was calling the 'NASA' convention. This is a rotation order (assuming the convention that the 'Z' axis is up) of zxy. I need an algorithm for all rotation orders. Possibly the solution, then, is to take the zxy order conversion and derive from it five other conversions for the other rotation orders. I guess I was hoping there was a more 'overarching' solution. In any case, I am surprised that I haven't been able to find existing solutions out there. In addition, and this perhaps should be a separate question altogether, any conversion (assuming a known rotation order, of course) is going to select one Euler representation, but there are in fact many. For example, given a rotation order of yxz, the two representations (0,0,180) and (180,180,0) are equivalent (and would yield the same quaternion). Is there a way to constrain the solution using limits on the degrees of freedom? Like you do in IK and rigid body dynamics? i.e. in the example above if there were only one degree of freedom about the Z axis then the second representation can be disregarded. I have tracked down one paper which could be an algorithm in this pdf but I must confess I find the logic and math a little hard to follow. Surely there are other solutions out there? Is arbitrary rotation order really so rare? Surely every major 3D package that allows skeletal animation together with quaternion interpolation (i.e. Maya, Max, Blender, etc) must have solved exactly this problem?

  • How to capture live camera frames in RGB with DirectShow

    - by Jonny Boy
    I'm implementing live video capture through DirectShow for live processing and display. (Augmented Reality app). I can access the pixels easily enough, but it seems I can't get the SampleGrabber to provide RGB data. The device (an iSight -- running VC++ Express in VMWare) only reports MEDIASUBTYPE_YUY2. After extensive Googling, I still can't figure out whether DirectShow is supposed to provide built-in color space conversion for this sort of thing. Some sites report that there is no YUV<-RGB conversion built in, others report that you just have to call SetMediaType on your ISampleGrabber with an RGB subtype. Any advice is greatly appreciated, I'm going nuts on this one. Code provided below. Please note that The code works, except that it doesn't provide RGB data I'm aware that I can implement my own conversion filter, but this is not feasible because I'd have to anticipate every possible device format, and this is a relatively small project // Playback IGraphBuilder *pGraphBuilder = NULL;

  • Converting .eps to .jpg

    - by Slinky
    Our print team saves raster images as .eps files. We need to convert about 11000 .eps to .jpg. We are using ImageMagick (with Ghostprint) on Linux. The conversion occurs but the resulting .jpg is not the same size as the source .eps - It's about 1/2 the size. Probably a problem converting a vector to a raster. Any way to solve this?

  • Adding distance to a GPS coordinate

    - by fgs
    Hi! I'm trying to generate some points at random distances away from a fixed point using GPS. How can I add distance in meters to a GPS coordinate? I've looked at UTM to GPS conversion but is there a simpler method to achieve this? I'm working on Android platform just in case. Cheers, fgs
