  • How does Android emulator performance compare to real device performance?

    - by uj2
    I'm looking into writing an Android game, tough I don't curerntly own an Android device. For those of you who own a device, how does the performance on the emulator relate to real device performance? I'm especially interested in graphics related tasks. This obviously depends on both the machine running the emulator, and the specific device in question, but I'm talking rough numbers here. This question is a duplicate, but since that post is heavily outdated, I figured it's irrelevant by now.

  • UppercuT &ndash; Custom Extensions Now With PowerShell and Ruby

    Arguably, one of the most powerful features of UppercuT (UC) is the ability to extend any step of the build process with a pre, post, or replace hook. This customization is done in a separate location from the build so you can upgrade without wondering if you broke the build. There is a hook before each step of the build has run. There is a hook after. And back to power again, there is a replacement hook. If you dont like what the step is doing and/or you want to replace its entire functionality,...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Is it bad to explicitly compare against boolean constants e.g. if (b == false) in Java?

    - by polygenelubricants
    Is it bad to write: if (b == false) //... while (b != true) //... Is it always better to instead write: if (!b) //... while (!b) //... Presumably there is no difference in performance (or is there?), but how do you weigh the explicitness, the conciseness, the clarity, the readability, etc between the two? Note: the variable name b is just used as an example, ala foo and bar.

  • In Ruby Compare 2 lines in a log file which BOTH contain the SAME "WORD" but ONLY print out the line

    - by kamal
    here are sample lines Apr 9 11:53:26 skip [2244]: [2244] ab-cd-ef:cc [INFO] A recoverable error has occurred some other log lines .. .... Apr 9 12:53:26 skip [2244]: [2244] ab-cd-ef:cc [INFO] A recoverable error has occurred now the LATEST line would have to be one with the latest Date String, and THAT is the one that needs to be printed, plus the NEXT time the parser runs on the log file, somehow the previous LATEST line has to be compared with the Existing latest one, and it CAN e the case, that NOTHING Changed and the OLD line is STILL the latest one, OR there is a NEW line, but ONLY the NEW log line should be printed and NOT if there is NO NEW log Entry.

  • Google Maps custom marker - can the iframe accept one like the static maps?

    - by alex
    I was reading the static maps API, and it says you can include a custom marker in the GET params. You simply link to an image file. I now have a second Google Map within an iframe, and was wondering if you can attach custom markers via the GET params to it? Here is the src attribute of the iframe currently. http://maps.google.com/maps?f=q&source=s_q&hl=en&geocode=&q=111+Fake+Street+Noosaville+Queensland+Australia&ie=UTF8&output=embed I can't seem to find the documentation on how to do this, if possible. Is this possible?

  • what is the best way to have a Generic Comparer

    - by oo
    I have a lot of comparer classes where the class being compared is simply checking the name property of the object and doing a string compare. For example: public class ExerciseSorter : IComparer<Exercise> { public int Compare(Exercise x, Exercise y) { return String.Compare(x.Name, y.Name); } } public class CarSorter : IComparer<Car> { public int Compare(Car x, Car y) { return String.Compare(x.Name, y.Name); } } what is the best way to have this code generic so i dont need to write redundant code over and over again.

  • Custom HTML Tags: Are there any specifications stating a standard way to handle them?

    - by blesh
    It seems like for years they've just been given default styling and inline display. Is there a spec somewhere that has dictated this? I've looked over the RFC's but I'm not particularly good with RFC-ese, and I didn't notice anything anywhere. For example <body> Some content <mycustomtag>something else</mycustomtag> more content. </body> I can still style it with CSS, and the browser doesn't outright vomit... so it seems like there is some sort of expected behavior. Was that dictated by a specification?

  • How to handle Application_BeginRequest using a custom filter in asp.net mvc?

    - by denis_n
    How to handle Application_BeginRequest using a custom filter in asp.net mvc? I want to restore session only for one route (~/my-url). I would be cool, if I could create a custom filter and handle that. protected void Application_BeginRequest(object sender, EventArgs e) { var context = HttpContext.Current; if (string.Equals("~/my-url", context.Request.AppRelativeCurrentExecutionFilePath, StringComparison.OrdinalIgnoreCase)) { string sessionId = context.Request.Form["sessionId"]; if (sessionId != null) { HttpCookie cookie = context.Request.Cookies.Get("ASP.NET_SessionId"); if (cookie == null) { cookie = new HttpCookie("ASP.NET_SessionId"); } cookie.Value = sessionId; context.Request.Cookies.Set(cookie); } }

  • How to compare if string has a enter key in the end using jquery/javascript?

    - by user144842
    I have a string value from a user input box. I have to figure out if last char is a enter key (line feed). Thats the code. Here I am checking if last char has a whitespace. Now I also have to check if last char is enter key (carriage return or line feed). How can i do this? var txt = $get("<%= txtUserText.ClientID %>"); if (txt.value.substring(txt.value.length -1) !== ' ' || <checkifLastCharIsEnterKey>) //my code to take action **I don't think i need a keypress or keyup event because this above piece of code is not invoked at the time of user input.

  • How to allow sorting in the Django admin by a custom list_display field, which doesn't have a DB fie

    - by Gj
    I have a custom list_display field which is responsible for a column of integers in one of my admin pages. I need to allow staff members to sort according to it. There's a solution for how to acheive that if the integer represents a count/average/etc of some DB field, which is not the case for me. [ the solution for that case is here: http://stackoverflow.com/questions/2168475/django-admin-how-to-sort-by-one-of-the-custom-list-display-fields-that-has-no-da ] Any ideas how I can achieve this sorting without actually creating and maintaining a DB field for the values?

  • How do I handle editing of custom types in a C# datagridview?

    - by Ian Hopkinson
    I have a datagridview in which one column contains a custom class, which I have set using: dgvPeriods.Columns[1].ValueType = typeof(ExDateTime); It is rigged up to display correctly by handling the CellFormatting event, but I'm unsure what event to handle for cell editing. In the absence of doing anything I get a FormatException as the datagridview tries to convert String to ExDateTime as I try to move focus out of the edited cell. I tried adding type conversion to my ExDateTime custom class: public static implicit operator ExDateTime(string b) { return new ExDateTime(b); } But this this didn't work. I also tried handling the DataError event, but this seems to fire too late. The datagridview is not databound.

  • Custom Folders in SSMS Object Explorer? Yes, we can!

    - by Luca Zavarella
    When you have a huge objects’ number in SSMS Object Explorer, you often get lost in finding items. So it’d be useful to catalog those objects in folders, in order to follow an application’s logical layer subdivision, for example. There is a fantastic add-in for SSMS that helps us to do that: http://www.sqltreeo.com The developer of this add-in has written a related post in his blog: http://www.sqltreeo.com/wp/dowload-free-ssms-add-in-to-create-own-folder-for-database-objects/ So another useful tool to add to our  SQL Server toolbox

  • Is recursion preferred compare to iteration in multicore era?

    - by prM
    Or say, do multicore CPUs process recursion faster than iteration? Or it simply depends on how one language runs on the machine? like c executes function calls with large cost, comparing to doing simple iterations. I had this question because one day I told one of my friend that recursion isn't any amazing magic that can speed up programs, and he told me that with multicore CPUs recursion can be faster than iteration. EDIT: If we consider the most recursion-loved situation (data structure, function call), is it even possible for recursion to be faster?

  • Is there a IDE/compiler PC benchmark I can use to compare my PCs performance?

    - by RickL
    I'm looking for a benchmark (and results on other PCs) which would give me an idea of the development performance gain I could get by upgrading my PC, also the benchmark could be used to justify the upgrade to my boss. I use Visual Studio 2008 for my development, so I'd like to get an idea of by what factor the build times would be improved, and also it would be good if the benchmark could incorporate IDE performance (i.e. when editing, using intellisense, opening code files etc) into its result. I currently have an AMD 3800x2, with 2GB RAM on Vista 32. For example, I'd like to know what kind of performance gain I'd see in Visual Studio 2008 with a Q6600, 4GB RAM on Vista 64. And also with other processors, and other RAM sizes... also see whether hard disk performance is a big factor. EDIT: I mentioned Vista 64 because I'm aware that Vista 32 can only use 3GB RAM maximum. So I'd presume that wanting to use more RAM would require Vista 64, but perhaps it could still be slower overall there is a large overhead in using the 32 bit VS 2008 on 64 bit OS.

  • How do the major C# DI/IoC frameworks compare?

    - by Slomojo
    At the risk of stepping into holy war territory, What are the strengths and weaknesses of these popular DI/IoC frameworks, and could one easily be considered the best? ..: Ninject Unity Castle.Windsor Autofac StructureMap Are there any other DI/IoC Frameworks for C# that I haven't listed here? In context of my use case, I'm building a client WPF app, and a WCF/SQL services infrastructure, ease of use (especially in terms of clear and concise syntax), consistent documentation, good community support and performance are all important factors in my choice. Update: The resources and duplicate questions cited appear to be out of date, can someone with knowledge of all these frameworks come forward and provide some real insight? I realise that most opinion on this subject is likely to be biased, but I am hoping that someone has taken the time to study all these frameworks and have at least a generally objective comparison. I am quite willing to make my own investigations if this hasn't been done before, but I assumed this was something at least a few people had done already. Second Update: If you do have experience with more than one DI/IoC container, please rank and summarise the pros and cons of those, thank you. This isn't an exercise in discovering all the obscure little containers that people have made, I'm looking for comparisons between the popular (and active) frameworks.

  • How do I programmatically add an Android Gestures view to a custom view?

    - by user351201
    I have a custom view that works fine and I'm trying to get gestures into it. The most common technique I see is to add XML, such as this (from Android docs: My view is within a RelativeView and when I attempt to reference this GetureOverlayView, I get an exception. I've also tried to connect within my existing custom view class, like this: mGestures = new GestureOverlayView(context, attrs); mGestures.addOnGesturePerformedListener(this); But the callback is never invoked. Can someone see my errors or suggest a better way that will allow me to get gesture callbacks?

  • How can I track scrolling in a Google Analytics custom report?

    - by SnowboardBruin
    I want to track scrolling on my website since it's a long page (rather than multiple pages). I saw several different methods, with and without an underscore for trackEvent, with and without spaces between commas <script> ... ... ... ga('create', 'UA-45440410-1', 'example.com'); ga('send', 'pageview'); _gaq.push([‘_trackEvent’, ‘Consumption’, ‘Article Load’, ‘[URL]’, 100, true]); _gaq.push([‘_trackEvent’, ‘Consumption’, ‘Article Load’, ‘[URL]’, 75, false]); _gaq.push([‘_trackEvent’, ‘Consumption’, ‘Article Load’, ‘[URL]’, 50, false]); _gaq.push([‘_trackEvent’, ‘Consumption’, ‘Article Load’, ‘[URL]’, 25, false]); </script> It takes a day for counts to load with Google Analytics, otherwise I would just tweak and test right now.

  • In SQL Server what is most efficient way to compare records to other records for duplicates with in

    - by Glenn
    We have an SQL Server that gets daily imports of data files from clients. This data is interrelated and we are always scrubbing it and having to look for suspect duplicate records between these files. Finding and tagging suspect records can get pretty complicated. We use logic that requires some field values to be the same, allows some field values to differ, and allows a range to be specified for how different certain field values can be. The only way we've found to do it is by using a cursor based process, and it places a heavy burden on the database. So I wanted to ask if there's a more efficient way to do this. I've heard it said that there's almost always a more efficient way to replace cursors with clever JOINS. But I have to admit I'm having a lot of trouble with this one. For a concrete example suppose we have 1 table, an "orders" table, with the following 6 fields. order_id, customer_id product_id, quantity, sale_date, price We want to look through the records to find suspect duplicates on the following example criteria. These get increasingly harder. 1. Records that have the same product_id, sale_date, and quantity but different customer_id's should be marked as suspect duplicates for review. 2. Records that have the same customer_id, product_id, quantity and have sale_dates within five days of each other should be marked as suspect duplicates for review 3. Records that have the same customer_id, product_id, but different quantities within 20 units, and sales dates within five days of each other should be considered suspect. Is it possible to satisfy each one of these criteria with a single SQL Query that uses JOINS? Is this the most efficient way to do this?
