  • Can documents indexed with Solr on JDK6 be retrieved using only lucene api on JDK1.4?

    - by huynhjl
    My runtime environment is still on JDK1.4 but I like the Solr features related to how documents are ingested and indexed. Would I be able to index my documents using Solr offline on a recent version of the JDK, copy the index over and use it in my runtime environment with an older version of the JDK? Version wise, Solr 1.4.0 uses Apache Lucene 2.9.1 which is JDK1.4 compatible. (but Solr itself requires JDK5). Assuming what I'm trying to do is even possible, what features would I lose if I search Solr indices only with the Lucene API?

Interfaces for barcode scanning (of ISBN code) 3. Integration with Amazon ( for reviews and ratings) 4. All the usual library facilities (Search, Checkin, checkout, checkout history, user reviews, user ratings etc). 5. Nice to have features - More personalization, booking of titles in advance, recommending books to select users etc.

  • Another Java vs. Scala perspective - is this typical?

    - by Alex R
    I have been reading about Scala for a while and even wrote some small programs to better understand some of the more exoteric features. Today I decided to do my first "real project", translating some 60 lines of ugly Java code to Scala to rewrite it using the better pattern-matching features (why? because the Java version was becoming hard to maintain due to excessive combination of regex and conditionals). About halfway through the editing process, Eclipse thew up this error: I get the general impression that the Scala IDE in Eclipse is a lot buggier and less complete than its Java equivalent. Is this correct or do I just have a bad installation? Is there a better IDE for Scala?

  • Upgrading a SharePoint list instance that was deployed via feature

    - by Goldmember
    I'm curious how others address this issue. Using VSEWSS 1.3, I have created a site content type, a list definition (w event receivers), and a list instance. All of them are in the same WSP solution and each is activated individually via features. Now let's assume that all the features have been activated for some time, and the list instance contains a number of items (that can't be deleted). Now suppose I need to make a change to the schema.xml (inject some javascript, modify views, whatever) of the list. Is it even possible to "upgrade" the schema of the existing list instance? Otherwise I would think I'm stuck creating a new instance and copying items over.

  • What is the best PHP framework for building a website around a heavily relational PostgreSQL databas

    - by Kenaniah
    First of all, the framework of choice needs to have excellent support for PostgreSQL. I don't care about MySQL because it doesn't have half of the features the application I will be porting requires. (And when I say excellent support, I mean that their approach to database drivers has not been solely trained in MySQL). The ideal framework: Should take full advantage of PHP 5.3 and PostgreSQL 8.4 features Should support new technologies such as OpenID and social networking Should support complex relationships between database relations Should have an intelligent validation system Should have a basic library of helpful views (such as pagination, navigation, etc) Should probably be MVC based Should have excellent documentation and an active development community Should namespace classes intelligently What I'm looking for might be more of a library of utilities, as I really don't want to be restricted by the framework in what I can and can not do. I have my own small library of core classes that take care of business logic, and I will most likely want to integrate those with the new framework as well. Thanks!

  • How to access SharePoint web part properties?

    - by shannon.stewart
    I have created a feature for SharePoint 2007 that has a web part. I have added a custom property to the web part like so: [Personalizable(PersonalizationScope.Shared)] [WebBrowsable(true)] [Category("My Custom Properties")] [WebDisplayName("ServiceURL")] [WebDescription("The URL for the Wcf service")] public string ServiceURL { get; set; } Along with this web part, I've added a custom page that the web part will have a link to. I would like to reference the web part property from the custom page, but I don't know where these properties are stored. I've tried to access it using the code below, but both property collections don't have any properties stored. SPFeaturePropertyCollection spProperties = SPContext.Current.Site.Features[this.FeatureGuid].Properties; or SPFeaturePropertyCollection spProperties = SPContext.Current.Site.Features[this.FeatureGuid].Definition.Properties; My question is how can I get a reference to the web part property from other pages?

  • How did Perl gain a reputation for being a write-only language?

    - by Andrew Grimm
    How did Perl gain a reputation (deserved, undeserved, or used to be deserved, no longer so) of being a "write only language"? Was it The syntax of the language Specific features that were available in the language Specific features not being available in the language (or at least old versions of it) The kind of tasks Perl was being used for The kind of people who use Perl (people who aren't full-time programmers) Criticism from people committed to another language Something else? Background: I'd like to know if some aspects that gave Perl the reputation of being write-only also apply to other languages (specifically ruby). Disclaimer: I recognise that Perl doesn't force people to do write-only code (can any language?), and that you can write bad code in any language.

  • Is VS2010 Premium Worth the Price?

    - by WindyCityEagle
    I know this is somewhat subjective, but I can't find an honest answer anywhere. Everything concerning VS2010 are Microsoft marketing materials. Our small group is going to upgrade to VS2010(mostly for F# and the new threading features), but we can't decide between the Professional and Premium versions. The integrated testing features in Premium sound good, but I can' figure out if they're worth the 10x increase in cost between the two versions(Professional is ~549, Premium is ~5400). Has anyone been faced with a similar decision? What swayed you one way or the other?

  • dijit/form/Select broken in Internet Explorer using Esri Javascript 3.7

    - by disuse
    After developing a web map app in Firefox, I tested my code in Internet Explorer (company standard) to discover that the dijit/form/Select is misbehaving using the latest Esri JavaScript v3.7. The issue I am seeing is that the Select will not update/change from the first option in the list when using v3.7. If I bump the version down to 3.6, it works as expected. I've tried IE browser modes from 7 to 10 and am experiencing the same behavior between all of them. Can someone confirm they are experiencing the same thing? Example in 3.7 - http://jsbin.com/aVIsApO/1/edit Example in 3.6 - http://jsbin.com/odIxETu/7/edit Codeblock var url = "http://services.arcgis.com/V6ZHFr6zdgNZuVG0/ArcGIS/rest/services/Street_Trees/FeatureServer/0"; var frmTrees; require([ "esri/tasks/query", "esri/tasks/QueryTask", "dojo/dom-construct", "dijit/form/Select", "dojo/parser", "dijit/registry", "dojo/on", "dojo/ready", "dojo/_base/connect", "dojo/domReady!" ], function( Query, QueryTask, domConstruct, Select, parser, registry, on, ready, connect ) { ready(function() { frmTrees = registry.byId("trees"); var qt = new QueryTask(url); var query = new Query(); query.where = "FID < 25"; query.orderByFields = ["qSpecies"]; query.returnGeometry = false; query.outFields = ["qSpecies", "TreeID"]; query.groupByFieldsForStatistics = ["qSpecies"]; //query.returnDistinctValues = true; qt.execute(query, function(results) { //var frm_domain_area = dom.byId("domain_area"); var testVals = {}; for (var i = 0; i < results.features.length; i++) { var id = results.features[i].attributes.TreeID; var desc = results.features[i].attributes.qSpecies; if (!testVals[id]) { testVals[id] = true; var selectElem = domConstruct.create("option",{ label: desc + " (" + id + ")", value: id }); frmTrees.addOption(selectElem); } } }); frmTrees.on("change", function() { console.debug(frmTrees.get("value")); }); }); });

  • How to compare/merge between XIB files?

    - by sasayins
    Hi guyz, I have these two XIB files. The first one edited by my friend to add features and to other one edited by my self and add another features. My problem is how can i merge the two files? I know that XIB files are XML based and I can use some compare tools to merge it. But I think there will be some conflicts. What is the best way to compare or merge between XIB files? Thanks a lot guys. sasayins

  • g++ and c++0x specification support

    - by SepiDev
    although it's been said that the support for c++0x new features in g++ are in experimental mode, many gcc developer claimed that you can use most of the new features in your codes and get the program to work. but when I try to compile this simple program it results in segmentation fault. Why? #include <thread> #include <iostream> void my_thread_func() { std::cout<<"hello"<<std::endl; } int main() { std::thread t(my_thread_func); t.join(); } g++ -std=c++0x -Wall -o run main.cc

  • SDL versus GLFW?

    - by user697111
    What are the pros and cons to each? It seems they serve the same purpose. I have a few demos with each and they seem about the same. Performance or cross platform wise, is one better than the other? The only thing I notice is that SDL seems to have more "helper" libraries (fonts, images, mixer, built in sound support, etc). On its site, GLFW claims to be more "OpenGL" focused, but still have to use a GLEW to get any newer OpenGL features (same with SDL). I guess I'm leaning towards using SDL now (more mature, more features, more community). Are there any reasons I've missed why GLFW stands out and I should use it instead of SDL?

  • Should I use Drupal or Kohana-type framework for a web "application"

    - by Andres
    The debate is that I need a PHP Framework/Drupal with the flexibility to add custom features to a potentially large application (web and with an api). However, with a framework, like Kohana, I see myself tackling and re-inventing the wheel with the simple stuff like account management and cms stuff. Account management and quick data collection, like fast form creation, are tedious in Kohana but appear incredible simple in Drupal. On the other hand, based on my limited Drupal experience, I doubt building rapid custom "features" and allowing users to create "groups" and to manage their own roles within those groups is something Drupal can easily accomplish. To simplify, is Drupal capable of true Web Applications; where the application is a service and provides custom results to each user? Can it provide a dashboard-like interface for users to change their settings or preferences? Can it aggregate data from particular users to provide better results/info to others? If so, please point me to some knowledge :-)

  • CodeRush Tricks of the Trade

    - by dr. evil
    I was using CodeRush quite while ago and now I'm planning to use it again. I've install the trial but I forgot all cool features except Alt + Home (drop a marker). And when you don't know some cool tricks it's really like burning money (since it's not cheap for personal use) What do you like about it? What are your best features? My best feature is marker: Alt + Home (and use escape to go back) P.S Dear Devxpress, if you think I helped you by asking this question I can accept some donations, a free license of CodeRush would be nice! Currently What I like most ps/pi etc. shortcut to create properties cc to create constructors pressing tab to navigate between the references F12 to find references in new cool window Ctrl + Shift + . for recent files Ctrl + Shift + Q for jumping to any function / class fe/fi for "for loops"

  • C# - How to make a custom installer for games, etc?

    - by Dodi300
    Hello. Can anyone tell me how to create a custom installer to 'install' games. I say custom meaning I don't want the user to have the option where the game is installed. I want it to be a straight forward process, maybe with just one loading bar. The program I'm developing is a 'center' for game playing, which includes a community and other features, such as a timer that records how long a game is played for. I just thought that installing each game in one place, with a simple installer would make the program easier to use. It also will allow me to do other features as the games will all be installed in one place. No need for the user to specify where the game is installed. Would this be possible? Thanks.

  • Missing safe control entry

    - by Stefan Hennicken
    I've got a working hello-world like webpart for my SPS3.0 I can compile, pack and deploy it using VS2008, makecab.exe and stsadm. So I know the theory of deploying sharepoint webparts. My problem: After I inserted an additional .webpart file, an elements.xml and a feature.xml to deploy the .webpart file and get knowledge about adding features to my webpart, the deployed webpart is missing its safe control entry in the web.config. But the dll can be found in the gac and my features are also deployed to the right folders. I didn't change anything in my manifest.xml especially not in it's -tag, because it definitely worked before i added my additional feature files. Can anybody help me? Should i provide you some code snippets? Thanks Stefan

  • Why are static classes considered “classes” and “reference types”?

    - by Timwi
    I’ve been pondering about the C# and CIL type system today and I’ve started to wonder why static classes are considered classes. There are many ways in which they are not really classes: A “normal” class can contain non-static members, a static class can’t. In this respect, a class is more similar to a struct than it is to a static class, and yet structs have a separate name. You can have a reference to an instance of a “normal” class, but not a static class (despite it being considered a “reference type”). In this respect, a class is more similar to an interface than it is to a static class, and yet interfaces have a separate name. The name of a static class can never be used in any place where a type name would normally fit: you can’t declare a variable of this type, you can’t use it as a base type, and you can’t use it as a generic type parameter. In this respect, static classes are somewhat more like namespaces. A “normal” class can implement interfaces. Once again, that makes classes more similar to structs than to static classes. A “normal” class can inherit from another class. It is also bizarre that static classes are considered to derive from System.Object. Although this allows them to “inherit” the static methods Equals and ReferenceEquals, the purpose of that inheritance is questionable as you would call those methods on object anyway. C# even allows you to specify that useless inheritance explicitly on static classes, but not on interfaces or structs, where the implicit derivation from object and System.ValueType, respectively, actually has a purpose. Regarding the subset-of-features argument: Static classes have a subset of the features of classes, but they also have a subset of the features of structs. All of the things that make a class distinct from the other kinds of type, do not seem to apply to static classes. Regarding the typeof argument: Making a static class into a new and different kind of type does not preclude it from being used in typeof. Given the sheer oddity of static classes, and the scarcity of similarities between them and “normal” classes, shouldn’t they have been made into a separate kind of type instead of a special kind of class?

  • Time to ignore IE?

    - by Delan Azabani
    In this answer: http://stackoverflow.com/questions/2781013/does-anyone-have-a-easy-to-use-png-fix-for-ie/2781041#2781041 which got voted down considerably, I point out the need to ignore Internet Explorer, or at least its old version 6, for the following reasons: It is hard to hack for, and some features don't exist at all The more you hack for IE, the longer people blindly use it (vicious cycle) My website, azabani.com, doesn't hack for IE at all. The layout looks somewhat broken in the browser, and most of my projects require features not present in IE's codebase. I would like to know if you support my view, or if you share views with those who downvoted my answer.

  • Python -- what is NOT in 2.7 that IS in 3.1? So many things have been back-ported, what is NOT?

    - by StuFuller
    I've been following the saga of Python 3.x and have watched the 3.x features gradually getting back-ported to the 2.x line. Most of the libraries I use haven't been ported and some (e.g. Twisted) seem covertly or overtly hostile to 3.x to varying degrees. At any rate, there has been very little movement towards compatible versions of many of them. Expecially the larger ones. So, my question is, with all the features that have been backported, what is still available in 3.x that's NOT been back-ported? It's pretty easy to find what has been backported, but not what's left. Right now, porting to 3.x just seems like all pain, and I can't see the gain; maybe an "Only in 3.x" list would let me see the light... Thanks, Stu

  • Differences in MS Office Charts

    - by simendsjo
    I'm about to do some Office integration creating charts from some data-sources and adding them to PPT slides. But some coworkers are saying using PPT charts is suboptimal as they are missing features of Excel charts, and are different in many ways. They're unable to come up with examples, and so am I... I found the following blog about Office2007, saying there are some differences in the programming model, but that they all use the same underlying engine. Are there really any differences in the capabilities of the charts? Is it mostly UI issues? What features are different/missing from PPT charts? Are these issues resolved in Office2010?

  • Which PHP framework for a RoR developer?

    - by Horace Ho
    For one specific client I have to use PHP. This and this question were 2 years old. I'd like to know is there any update of opinion for year 2010? My background on web development is mainly rails. I can code in PHP (for example, write a module for Drupal) but never used any PHP framework for any project. I can see the following potential features to be needed in my project: authlogic-like user access control will_paginate-like paging for long listings paperclip-like simple file upload prawn-like PDF generation restful url and my personal favorite ruby/rails features: activerecord <% @list.each do |item| %> synstax instead of for ($i=1; $i<=$row_num; $i++) ... rake:db migrate script/console Thanks!
