  • subplot matplotlib wrong syntax

    - by madptr
    I am using matplotlib to subplot in a loop. For instance, i would like to subplot 49 data sets, and from the doc, i implemented it this way; import numpy as np import matplotlib.pyplot as plt X1=list(range(0,10000,1)) X1 = [ x/float(10) for x in X1 ] nb_mix = 2 parameters = [] for i in range(49): param = [] Y = [0] * len(X1) for j in range(nb_mix): mean = 5* (1 + (np.random.rand() * 2 - 1 ) * 0.5 ) var = 10* (1 + np.random.rand() * 2 - 1 ) scale = 5* ( 1 + (np.random.rand() * 2 - 1) * 0.5 ) Y = [ Y[k] + scale * np.exp(-((X1[k] - mean)/float(var))**2) for k in range(len(X1)) ] param = param + [[mean, var, scale]] ax = plt.subplot(7, 7, i + 1) ax.plot(X1, Y) parameters = parameters + [param] ax.show() However, i have an index out of range error from i=0 onwards. Where can i do better to have it works ? Thanks

  • Multimap Space Issue: Guava

    - by Arpssss
    In my Java code, I am using Guavas Multimap (com.google.common.collect.Multimap) by using this: Multimap< Integer, Integer Index = HashMultimap.create() Here, Multimap key is some portion of URL and value is another portion of URL (converted into integer). Now, I assign my JVM 2560 Mb (2.5 GB) heap space (by using Xmx and Xms). However, it can only store 9 millions of such (key,value) pairs of integers (approx 10 million). But, theoretically (according to memory occupied by int) it should store more. Can anybody help me, 1) Why is this happening (means Multimap is taking lots of space) ? I checked my code with out inserting pairs in Multimap, it takes only 1/2 MB space. 2) Is there any other way or home-baked solution to solve this space issue ? More clearly, how to solve this memory issue ? Thanks in advance and any idea is perfectly OK for me.

  • Trouble Getting a Locally Hosted Copy of the English Language Wiktionary to include the Translations Sections

    - by user1436026
    I used MWDumper - http://www.mediawiki.org/wiki/Mwdumper - to import the xml dump of the English Language Wiktionary (specifically the file named enwiktionary-20120930-pages-meta-current.xml,) to my local server. I have found that under the Translations section (on each page for each English word,) next to the name of each language where I should be able to see the definition in a foreign language, I instead see Template:Tø, Template:T+, or Template:T- and I am not sure why this is. As an experiment, I also used WikiTaxi - http://www.yunqa.de/delphi/doku.php/products/wikitaxi/index - with the exact same XML dump and did not have this problem when viewing under WikiTaxi.exe. I have been searching through mediawiki.org looking for the answer, but have so far not been successful. I appreciate your help

  • Bugs in scroll-follow with Google map (Firefox and Safari)

    - by earlyriser
    A scroll follow effect is when a part of the web design is always visible, even when the window is scrolled. There are animated and static versions of this. The animated is ok http://robertomartinez.info/cobra/index.html But I prefer the fixed version, however I have some bugs: http://robertomartinez.info/cobra/index_fixed.html -In Firefox, when you scroll the page, you will see a kind of vertical cut in the lorem ipsum text (below the HERE indication). This is caused by the image tiles of the map, then if you drag and drop the map, the cut will appear in another side. -In Safari, when you scroll the page, the div follows, but the map images stay in the same position. Do you have solutions for theses issues? Thanks.

  • Remove items from one list in another

    - by coffeeaddict
    I'm trying to figure out how to traverse a generic list of items that I want to remove from another list of items. So lest say I have this as a hypothetical example List<car> list1 = GetTheList(); List<car> list2 = GetSomeOtherList(); I want to traverse list1 with a foreach and remove each item in List1 in List2. I'm not quite sure how to go about that as foreach is not index based.

  • Java List Sorting: Is there a way to keep a list permantly sorted automatically like TreeMap?

    - by david
    In Java you can build up an ArrayList with items and then call: Collections.sort(list, comparator); Is there anyway to pass in the Comparator at the time of List creation like you can do with TreeMap? The goal is to be able add an element to the list and instead of having it automatically appended to the end of the list, the list would keep itself sorted based on the Comparator and insert the new element at the index determined by the Comparator. So basically the list might have to re-sort upon every new element added. Is there anyway to achieve this in this way with the Comparator or by some other similar means? Thanks.

  • How do I change the list using mutable lists in Racket or Scheme?

    - by exOne
    I need your help Can anyone help me? first question This procedure should modify each element which’s index in the list is even. The value of the element should be equal to the new-element. For example: (define number-list (1 56 8 1 43 9 78)) (modify-even-indices number-list 10) The new list: 1 10 8 10 43 10 78 second question This problem is the extended version of Question 1. (modify-even-odd-indices my-list new-element modification-type) This procedure should modify each element according to the modification-type. The modification-type can be even or odd. For example: (define number-list (1 56 8 1 43 9 78)) (modify-even-odd-indices number-list 10 ‘even’) The new list: 1 10 8 10 43 10 78 (modify-even-odd-indices number-list 10 ‘odd’) The new list: 10 56 10 1 10 9 10

  • CodeIgniter Production and Developpement server on the same domain. (no subdomain)

    - by Onigoetz
    Hi, I googled this many times but now I have to ask it here. I want to make a workflow for a website for Developpement/Production. My constraint is that I use Facebook Connect (Facebook Graph now) so I need to have the dev and prod on the same domain and server. (to be able to log in and test the features) I thought I will edit the CodeIgniter Index.php to redirect if I have a specific user agent (I can edit the one of my firefox) You think it's a good Idea or you have a better one ? And now comes the eternal question : how can I deploy this the easy way ? should I use Capistrano or Phing ? or simply a script with SVN ? Please help me, I'm totally new to this Deployment thing. I used to work directly in production for my little websites or on other domains. but now it's not possible anymore.

  • PHP to C# and Vice versa

    - by Daniel Sh.
    I'm in this project: A web page that's gonna be used by the front-end company people to query and update data from a SQL DB. I'm working with visual studio and the code behind (C#) is almost done, so the interactions between SQL and C# and ok. My original idea was to work with ASP.NET which is familiar to me, but that's not gonna be possible. I have to switch to PHP. So, today is my first day learning PHP, checking http://php.net/manual/en/index.php and a lot of things seem quite similar to ASP.NET so I guess it won't be that hard. Anyways, some questions popped up quite fast as I wanted to script something else than a "hello world" . Is there an easy way to get/send C# variables from my class using a php page? I've read soemthing about using XML in order to do so, but still I'm scratching my head, is there another, easier, way to do this?

  • How to include named capture groups in java regex?

    - by jrummell
    I'm new to regex in Java and I can't figure out how to include named capture groups in an expression. I'm writing a ScrewTurn Image Converter for Confluence's Universal Wiki Converter. This is what I have: String image = "\\[image(?<align>auto)?\\|\\|{UP\\(((?<namespace>\\w+)\\.)?(?<pagename>[\\w-]+)\\)}(?<filename>[\\w- ]+\\.[\\w]+)\\]"; Pattern imagePattern = Pattern.compile(image, Pattern.CASE_INSENSITIVE); It's throwing this exception in Pattern.comiple(): java.util.regex.PatternSyntaxException: Unknown look-behind group near index 19 \[image(?<align>auto)?\|\|{UP\(((?<namespace>\w+)\.)?(?<pagename>[\w-]+)\)}(?<filename>[\w- ]+\.[\w]+)\] ^ I've used named capture groups like this before in C# (?<namedgroup>asdf), but not in Java. What am I missing?

  • database modeling for google app engine for multiple revison of entity.

    - by iamgopal
    hi, in my application ( kind of wiki clone ) - an article is frequently changing. and i need to track all changes that are done on that article. { text only. } one crude way i have done it, is to add a datetime property and create a new entity everytime something change. which is too much database wasting. { and also un-necessary index waste too. } and also need to re-create parent-child and entity relationships. i also have log which can show changes -- but i want some thing easier , so that jumping from one version to another version could be easier. ideas ? thanks.

  • routing paramenter returns null when only supplying first paramenter in MVC

    - by Ray ForRespect
    My issue is that I customer Map Route in MVC which takes three parameters. When I supply all three or just two, the parameters are passed from the URL to my controller. However, when I only supply the first parameter, it is not passed and returns null. Not sure what causes this behavior. Route: routes.MapRoute( name: "Details", // Route name url: "{controller}/{action}/{param1}/{param2}/{param3}", // URL with parameters defaults: new { controller = "Details", action = "Index", param1 = UrlParameter.Optional, param2 = UrlParameter.Optional, param3 = UrlParameter.Optional } // Parameter defaults ); Controller: public ActionResult Map(string param1, string param2, string param3) { StoreMap makeMap = new StoreMap(); var storemap = makeMap.makeStoreMap(param1, param2, param3); var model = storemap; return View(model); } string param1 returns null when I navigate to: /StoreMap/Map/PARAM1NAME but it doesn't return null when I navigate to: /StoreMap/Map/PARAM1NAME/PARAM2NAME

  • How might one detect the first run of a program?

    - by Julian H. Lam
    In my web application, users can download a .tar.gz archive containing the app files. However, because the MySQL database won't have been configured then, the user needs to run the install script located in ./install. I "catch" the user upon first run of the app by checking to see if the ./install directory exists. If so, the index.php page redirects the user to the install script. However, I was wondering if there were a more elegant way to "catch" a user upon first-run of a program. Someone on IRC suggested the web-server create a file .installed upon completion, but because the web server might not have write privileges to the web root directory, I can't rely on that. How would you go about solving this problem, or is my solution workable?

  • Designing a table to store EXIF data

    - by rafale
    I'm looking to get the best performance out of querying a table containing EXIF data. The queries in question will only search the EXIF data for the specified strings and return the row index on a match. With that said, would it better to store the EXIF data in a table with separate columns for each of the tags, or would storing all of the tags in a single column as one long delimited string suit me just as well? There are around 115 EXIF tags I'll be storing, and each record would be around 1500 to 2000 chars in length if concatenated into a single string.

  • Creating a stored procedure in SQL Server 2008 that will do a "facebook search"

    - by dig
    Hello, I'm trying to implement a facebook search in my system (auto suggest while typing). I've managed to code all the ajax stuff, but I'm not sure how to query the database. I've created a table called People which contains the fields: ID, FirstName, LastName, MiddleName, Email. I've also created a FTS-index on all those fields. I want to create a stored procedure that will get as a parameter the text inserted in the query box and returns the suggestions. For example, When I will write in the textbox the query "Joh Do" It will translate to the query: select * from People where contains(*, '"Joh*"') and contains(*, '"Do*"') Is there a way to do that in stored procedure? P.S I've tried to use the syntax select * from People where contains(*,'"Joh*" and "Do*"') but it didn't returned the expected results, probably because it needs to search the words on different fields. Is there a way to fix that? Thanks.

  • How can i test my DB speed? (Learning)

    - by acidzombie24
    I have design a database. Theres no columns with indexing, nor any code for optimizing. I am positive i should index certain columns since i search them a lot. My question is HOW do i test if any part of my database will be slow? ATM I am using sqlite and i will be switching to either MS Sql or MySql based on my host provider. Will creating 100,000 records in each table be enough? Or will that always be fast in sqlite and i need to do 1mil? Do i need 10mil before a database will become slow? Also how do i time it? I am using C# so should i use StopWatch or is there a ADO.NET/Sqlite function i should use?

  • How to convert an arbitrary object to String with EL? (calling toString())

    - by hstoerr
    Is there any way to call toString() on an object with the EL? (I need the String representation of an enum as index in a map in a JSP EL expression.) I hoped something like ${''+object} would work like in java, but EL isn't that nice, and there does not seem to be any function that does it. Clarification: I have a variable somemap that maps Strings to Strings, and I have a variable someenum that is an enumeration. I'd like to do something like ${somemap[someenum.toString()]}. (Of course .toString() does not work, but what does?)
