• HBase as web app backend

  - by NathanD

  Can anyone advise if it is a good idea to have HBase as primary data source for web-based application? My primary concern is HBase's response time to queries. Is it possible to have sub-second response? edit: more details about the app itself. Amount of data: ~500GB of text data, expect to reach 1TB soon Number of concurrent users using the app: up to 50 The app will be used to present reports about data stored in HBase, like how many times keyword "X" occured in last 24h. For ~80% of requests from that app I will know the exact key, 20% will be scans (I'm looking into HBase schema design related topics to make it run fast)

• ASP NET Custom Routing

  I have following patterns /invitation/mission/busstop -- return the list of busstops /invitation/mission/busstop/id -- return a specific busstop /invitation/mission/driver -- return the list of drivers /invitation/mission/driver/id -- return a specific driver /invitation/mission/driver/city/model/limit -- query driver accoring to city, model and age limit ... /invitation/questionair -- return the list of questionairs /invitation/questionair/id -- return a specific questionair /invitation/questionair/create -- create a new questionair /invitation/questionair/update/id -- update a questionair ... I expect the 'invitation' to be controller, and the rest to be action. Each of the above url should corresponds to a dedicated view page. Can anyone help me to design the routes? ===================================================================== I update the patterns, and add my expectation at the end of each url. Any suggest on the url patterns?

• Facebook insights for websites does not match on-site Facebook button counts

  - by Will

  I use Facebook Insights for websites and Facebook buttons on my site. However, the data reported by the two do not match. It always seems to be the case that the count reported by the buttons is significantly higher than the count reported in Facebook Insights. For example, this page http://www.appmyworld.com/blog/top-5-iphone-and-ipad-apps-of-the-week-10412.html has a count of 52 for Facebook which is made up of 19 likes, 21 shares and 12 comments according to AddThis and confirmed by http://sharedcount.com However, going into Facebook Insights for my website and looking at that specific page it shows only 4 total actions which is made up of 1 like and 3 shares. At the very least I would expect it to show a total count of 40 made up of 19 likes and 21 shares (I'm not sure it would track the 12 comments). Any thoughts on why this may be happening? My concern is if our website is not getting credit for the Facebook activity?

• what is the programmatic parlance for this phenomenon?

  - by deostroll

  Here is javascript code (jquery) for adding a row of images: var tr = $('<tr>'); var td = '<td><img src="myimg.jpg"/></td>'; tr.append(td).append(td).append(td); $('#mytable tbody tr:eq(0)').before(tr); tr.empty(); //I really don't need this line... Technically tr.empty() shouldn't have worked. It actually does the opposite of what I want. What is the techinical term for this behaviour - You've added tr to the DOM, but any jquery function calls to that object still works, where as you'd normally not expect it to work i.e. make changes to the DOM?

• What are the uses of svn copy?

  - by nav.jdwdw

  Example: $ svn copy foo.txt bar.txt A bar.txt When would you use this technique, and why? Will this command (taken from svn's "red book") creates a copy of <foo.txt> while preserving the history of it to be shared with <bar.txt>? If I'm changing <bar.txt>, what will happen to <foo.txt>? What are the equivalents to this in other modern systems (Clearcase, Accurev, Perforce)? Clarification: Let me emphasize the point I'm searching for: Is this kind of branching out on a file level? What happens if you use it in the same branch, i.e. create a copy of a file and than start changing that new file. all in the same branch? I understand that it is also used for tagging but what is interesting me is what to expect when performing <svn copy> On the file level

• different explanation

  - by Delirium tremens

  The following code echoes 5, not 10: $global_obj = null; class my_class { var $value; function my_class() { global $global_obj; $global_obj = &$this; } } $a = new my_class; $a->my_value = 5; $global_obj->my_value = 10; echo $a->my_value; "Upon first examination, it would seem that the constructor of my_class stores a reference to itself inside the $global_obj variable. Therefore, one would expect that, when we later change the value of $global_obj-my_value to 10, the corresponding value in $a would change as well. Unfortunately, the new operator does not return a reference, but a copy of the newly created object." Please, give me a different explanation.

• Time order of messages

  - by Aiden Bell

  Read (skimmed enough to get coding) through Erlang Programming and Programming Erlang. One question, which is as simple as it sounds: If you have a process Pid1 on machine m1 and a billion million messages are sent to Pid1, are messages handled in parallel by that process (I get the impression no) and(answered below) is there any guarantee of order when processing messages? ie. Received in order sent? If so, how is clock skew handled in high traffic situations for ordering? Coming from the whole C/Thread pools/Shared State background ... I want to get this concrete. I understand distributing an application, but want to ensure the 'raw bones' are what I expect before building processes and distributing workload. Also, am I right in thinking the whole world is currently flicking through Erlang texts ;)

• Why is Javascript's Math.floor the slowest way to calculate floor in Javascript?

  - by z5h

  I'm generally not a fan of microbenchmarks. But this one has a very interesting result. http://ernestdelgado.com/archive/benchmark-on-the-floor/ It suggests that Math.floor is the SLOWEST way to calculate floor in Javascript. ~~n, n|n, n&n all being faster. This seems pretty shocking as I would expect that people implementing Javascript in today's modern browsers would be some pretty smart people. Does floor do something important that the other methods fail to do? Is there any reason to use it?

• How can I access and change elements in this private readonly property?

  - by CrimsonX

  I'm trying to figure out how I am able to successfully change a "readonly" array. I have this: namespace ConsoleApplication1 { class Program { static void Main(string[] args) { MyClass myClass = new MyClass(); myClass.Time[5] = 5; // How is this legal? } } public class MyClass { private readonly uint[] time; public IList<uint> Time { get { return time; } } public MyClass() { time = new uint[7]; } } } As I Note above, I would expect that Time[5] would be illegal due to the fact that public IList Time does not have a setter. Additionally, how can I create an array in the constructor which is read-only and unchangeable outside of this class?

• Should I use Spring or Guice for a Tomcat/Wicket/Hibernate project?

  - by Trevor Allred

  I'm building a new web application that uses Linux, Apache, Tomcat, Wicket, JPA/Hibernate, and MySQL. My primary need is Dependency Injection, which both Spring and Guice can do well. I think I need transaction support that would come with Spring and JTA but I'm not sure. The site will probably have about 20 pages and I'm not expect huge traffic. Should I use Spring or Guice? Feel free to ask and followup questions and I'll do my best to update this.

• Are we using IoC effectively?

  - by Juliet

  So my company uses Castle Windsor IoC container, but in a way that feels "off": All the data types are registered in code, not the config file. All data types are hard-coded to use one interface implementation. In fact, for nearly all given interfaces, there is and will only ever be one implementation. All registered data types have a default constructor, so Windsor doesn't instantiate an object graph for any registered types. The people who designed the system insist the IoC container makes the system better. We have 1200+ public classes, so its a big system, the kind where you'd expect to find a framework like Windsor. But I'm still skeptical. Is my company using IoC effectively? Is there an advantage to new'ing objects with Windsor than new'ing objects with the new keyword?

• Is it possible to send an automated email with dynamic content in Rails

  - by Danny McClelland

  Hi Everyone, I am looking into the best way of doing the following: I have a model called Kase, and when a user creates a new case then are taken to the show view as you would expect. I am trying to work out what the best way of sending an automated email between those two events is. I would need to include in the email the content of a couple of the fields, ideally I am looking for a way of just typing out the email and adding the same snippets that are in the show view for each of the fields I need. I am using the Base App from Github so the email sending is already setup for the user authentication and registration, but I'm not sure where to begin. The reason I want to send the email is to create a new Case in our Highrise account, and I don't have a clue how to use the API. So I think the email sending is the easier way. Thanks, Danny

• Poll: Require Semicolons and Forbid Tables?

  - by George Bailey

  There are a few very serious but opinionated and subjective arguments that I know of. Two of them are Whether or not to use semicolons in the event they are optional. There is a vote as here that also includes reasons Whether or not to use tables for non tabular data. There more information here Since the semicolon question arises often in JavaScript and the tables thing in HTML then there are probably many who run into both. I sort of expect a person who is strict with semicolons also to be strict about avoiding tables. I will post four CW answers here to vote on. Please vote what you think is right. If you want to talk about the reasons then please use Semicolons: Do you recommend using semicolons after every statement in JavaScript? Tables: Start your own question under the polls tag and follow the design of the semicolons question.

• Overlapping images w/ image maps obstructing each other

  - by Hamster

  Information: The images have large transparent sections, so each must be overlapped to create the needed effect. Specifically, the clickable portions of each image are in weird trapezoid shapes meant to be pressed up against each other. Images have image maps with large portions being overlapped by the transparent portions of other nearby (trapezoid) images. I don't expect any change in z indexes will solve this... Combining the image files into a larger single one to overlay a single image map for each section seems less than ideal, especially since I may need to re-order or rename them later and such. Never mind hover animations and other possibilities down the road. What would be the best workaround?

• how to callback a lua function from a c function

  - by pierr

  Hi, I have a c function test_callback accepting a point to a function as the parameter and It will "callback" that function. //typedef int(*data_callback_t)(int i); int test_callback(data_callback_t f) { f(3); } int datacallback(int a ) { printf("called back %d\n",a); return 0; } //example test_callback(datacallback); // print : called back 3 Now, I want to wrap test_callback so that they can be called from lua, suppose the name is lua_test_callback ;and also the input parameter to it would be a lua function. How should I achieve this goal? function lua_datacallback (a ) print "hey , this is callback in lua" ..a end lua_test_callback(lua_datacallback) //expect to get "hey this is callback in lua 3 "

• iPhone Input with Stacked Views

  - by Forrest

  Hi, I've got a situation in an iphone application where buttons are not receiving input as I expect. Here's the setup: ViewMain - The main view full of various images and labels ViewOverlay - A HUD like overlay view with two UIButton objects. To create my scene I do the following: viewController.view = ViewMain [ViewMain addsubview:ViewOverlay] This view renders as expected, with ViewOverlay correctly rendered ontop of ViewMain. However the two buttons found inside ViewOverlay do not receive touch events and can not be pressed. Tapping them does nothing at all. I very well may be going about this in the entirely wrong direction. Any ideas?

• I DISTINCTly hate MySQL (help building a query)

  - by Alex Mcp

  This is staight forward I believe: I have a table with 30,000 rows. When I SELECT DISTINCT 'location' FROM myTable it returns 21,000 rows, about what I'd expect, but it only returns that one column. What I want is to move those to a new table, but the whole row for each match. My best guess is something like SELECT * from (SELECT DISTINCT 'location' FROM myTable) or something like that, but it says I have a vague syntax error. Is there a good way to grab the rest of each DISTINCT row and move it to a new table all in one go?

• Can silverlight detect or communicate across browser instances?

  - by isolatedIterator

  User starts up a silverlight application in their browser by navigating to a given URL. User then opens another browser and starts up the same silverlight application by navigating to the same URL. Can the second instance of the application detect that there is already an instance running on the same computer? Can it detect itself if both applications are running within the same browser instance? I would expect the answer to be 'no' but thought that i would ask it anyway. Otherwise i believe that i will have to setup a webservice and have each instance register itself and send requests to other instances from the same IP. does that sound reasonable?

• How to get user input for 2 digit data

  - by oneMinute

  In a HTML form user is expect to fill / select some data and trigger an action probably a http-post. If your only requested data field is a "2 digit" you can use html text input element get some data. Then you want to make it useful; enable user easily select data from a 'html select' But not all of your data is well-ordered so eye-searching within these data is somehow cumbersome. Because your data is meaningful with its relations. If there is no primary key for foreign key "12" it should not be shown. Vice versa if this foreign key occurs a lot, then it has some weight and could be displayed with more importance. So, what will be your way? a) Use text input to get data and validate it with regex, javascript, ... b) Use some dropdown select. c) Any other way ? Any answer will appreciated :)

• Force line-buffering of stdout when piping to tee

  - by houbysoft

  Usually, stdout is line-buffered. In other words, as long as your printf argument ends with a newline, you can expect the line to be printed instantly. This does not appear to hold when using a pipe to redirect to tee. I have a C++ program, a, that outputs strings, always \n-terminated, to stdout. When it is run by itself (./a), everything prints correctly and at the right time, as expected. However, if I pipe it to tee (./a | tee output.txt), it doesn't print anything until it quits, which defeats the purpose of using tee. I know that I could fix it by adding a fflush(stdout) after each printing operation in the C++ program. But is there a cleaner, easier way? Is there a command I can run, for example, that would force stdout to be line-buffered, even when using a pipe?

• Using the mpz_powm functions from the GMP/MPIR libraries with negative exponents

  - by Mihai Todor

  Please consider the following code: mpz_t x, n, out; mpz_init_set_ui(x, 2UL); mpz_init_set_ui(n, 7UL); mpz_init(out); mpz_invert(out, x, n); gmp_printf ("%Zd\n", out);//prints 4. 2 * 4 (mod 7) = 1. OK mpz_powm_ui(out, x, -1UL, n);//prints 1. 2 * 1 (mod 7) = 2. How come? gmp_printf ("%Zd\n", out); mpz_clear(x); mpz_clear(n); mpz_clear(out); I am unable to understand how the mpz_powm functions handle negative exponents, although, according to the documentation, it is supposed to support them. I would expect that raising a number to -1 modulo n is equivalent to inverting it modulo n. What am I missing here?
