• Using Drupal to build a directory listing? [on hold]

  - by Jim

  I am trying to create a form inside Drupal that will allow me to create a directory similar to this diagram: http://i.imgur.com/EtChBbG.jpg I tried looking into HTML tables but it is too basic for what I'm trying to do. How do I create a directory that can archive data in an alphabetical ordering? It also has to be able to sort by letters and other categories. Does anyone have an idea of how I should go about doing this? Thanks!

• usb keyboard stopped working in terminal window after update from 13.04 to 13.10

  - by Jim

  When I start the computer, I am logged in automatically. Using the keyboard, I type Ctrl+Alt+t, which brings up a terminal window, just like it should; however, nothing happens when I attempt to type into the terminal. If I change over to the guest account, I can type into the terminal, but (different problem here, I'll ask it separately unless someone is kind enough to answer it here) my password doesn't work for sudo or anything else. Elsewhere I read that Language support could fix it, but that won't accept my password either - and no, I haven't changed it lately. Also, my Plex Media Server seems to have disappeared. I'll re-install everything if necessary, but I sure would rather avoid that if possible

• Data recovery on a Samsung SV1203N HDD

  - by Jim Conace

  Let me start by saying that I am a beginner in Ubuntu, but pretty knowledgeable with Windows. I am having a strange problem trying to recover data from a Samsung SV1203N HDD (120 GiB). I have tried numerous things in both Windows 7 and Ubuntu 12.04 LTS (on a flash drive, an external HDD and a Live CD). This drive has some very important data on it and I am praying some of you Ubuntu geeks can help me get it back. Here's my problem. The HDD is clicking while I am booting, but it stops when I get into Ubuntu or Windows. It refuses to be detected in the bios, so I cant perform any tests on it. I have tried numerous things in both Windows (repair CD, Jumpers, etc.) and Ubuntu (Boot-Fix, GParted, Testdisk, Photorec, forcing a mount, etc.). But it all seems to lead me back to the fact that the drive is not being recognized in the BIOS. I've even tried chilling the drive in the fridge, which worked well for another drive I work on, and I recovered all of the data in Ubuntu flawlessly. I am assuming that since the drive stops clicking when I get into the OS' that there is hope for recovery. I am going to try an IDE/SATA to USB cable, and replacing the Logic Board, but I want to exhaust all other possibilities before I do that. Any help would be greatly appreciated Bye

• In C++ Good reasons for NOT using symmetrical memory management (i.e. new and delete)

  - by Jim G

  I try to learn C++ and programming in general. Currently I am studying open source with help of UML. Learning is my hobby and great one too. My understanding of memory allocation in C++ is that it should be symmetrical. A class is responsible for its resources. If memory is allocated using new it should be returned using delete in the same class. It is like in a library you, the class, are responsibility for the books you have borrowed and you return them then you are done. This, in my mind, makes sense. It makes memory management more manageable so to speak. So far so good. The problem is that this is not how it works in the real world. In Qt for instance, you create QtObjects with new and then hand over the ownership of the object to Qt. In other words you create QtObjects and Qt destroys them for you. Thus unsymmetrical memory management. Obviously the people behind Qt must have a good reason for doing this. It must be beneficial in some kind of way, My questions is: What is the problem with Bjarne Stroustrups idea about a symmetrical memory management contained within a class? What do you gain by splitting new and delete so you create an object and destroy it in different classes like you do in Qt. Is it common to split new and delete and why in such case, in other projects not involving Qt? Thanks for any help shedding light on this mystery!

• SVN X remains in tree-conflict

  - by Paul Knopf

  I am using VisualSVN (which uses Tortoise). I accidentally move a folder to a different location. When tries to move it back, SVN pukes with this error. It happened once before and I managed to do some random updates/commits, not knowing what I was doing and it was "fixed". I cannot pull the same magic again, so I need to know how to get my files and directory and of tree-conflict. Thanks!

• Lucene.NET 2.9 and BitArray/DocIdSet

  - by Paul Knopf

  I found a great example on grabbing facet counts on a base query. It stores the bitarray of the base query to improve the performance each time the a facet gets counted. var genreQuery = new TermQuery(new Term("genre", genre)); var genreQueryFilter = new QueryFilter(genreQuery); BitArray genreBitArray = genreQueryFilter.Bits(searcher.GetIndexReader()); Console.WriteLine("There are " + GetCardinality(genreBitArray) + " document with the genre " + genre); // Next perform a regular search and get its BitArray result Query searchQuery = MultiFieldQueryParser.Parse(term, new[] {"title", "description"}, new[] {BooleanClause.Occur.SHOULD, BooleanClause.Occur.SHOULD}, new StandardAnalyzer()); var searchQueryFilter = new QueryFilter(searchQuery); BitArray searchBitArray = searchQueryFilter.Bits(searcher.GetIndexReader()); Console.WriteLine("There are " + GetCardinality(searchBitArray) + " document containing the term " + term); The only problem is that I am using a newer version of Lucene.NET (2.9) and Filter.Bits is obsolete. We are told to use DocIdSet instead (rather than BitArray). I cannot found out how to do the bitArray.And(bitArray) with a docIdSet. I looked in reflector and found OpenIdSet which has And operations. Not sure if OpenIdSet is the route to go, I'm just stating. Thanks in advance!

• Lucene.NET performance

  - by Paul Knopf

  I have a website that runs of a third party search provider that is expensive. I am going to roll my own. Is Lucene.NET capable of ~25,000 products (or documents), each with maybe ten attributes used for filtering? I am looking to do a "narrow/drill down" or "faceted search". Does that sound like to much to ask from Lucene.NET?

• Lucene.NET faceted search.

  - by Paul Knopf

  I found a great tutorial on performing a faceted search. http://www.devatwork.nl/articles/lucenenet/faceted-search-and-drill-down-lucenenet/ This article does not explain how to retrieve the narrowed available attributes to filter from (for further drill down). Lets say I am looking for planners that are red. When I perform the faceted search, I want to return all available attributes to filter from that are red. Then when I add a "weekly format" filter, I want the attribute list to get even smaller, containing only filters available for the segmented group.

• Splunk QA? Is it stackoverflows database?

  - by Paul Knopf

  http://answers.splunk.com/ God please tell me that there is a stackoverflow API that I can hook into to port a genre of questions in a way that splunk has. If God has forsaken me, Joel or whomever it may concern, this would be awesome!

• Encoding a string as an integer .NET

  - by Paul Knopf

  I have a string that I would like represented uniquely as an integer. For example: A3FJEI = 34950140 How would I go about writing a EncodeAsInteger(string) method. I understand that the amount of characters in the string will make the integer increase greatly, forcing the value to become a long, not an int. Since I need the value to be an integer, I don't need the numerical representation to be entirely unique to the string. Maybe I can foreach through all the characters of the string and sum the numerical keycode of the character.

• XSD and plain text

  - by Paul Knopf

  I have a rest/xml service that gives me the following... <verse-unit unit-id="38009001"> <marker class="begin-verse" mid="v38009001"/> <begin-chapter num="9"/><heading>Judgment on Israel&apos;s Enemies</heading> <begin-block-indent/> <begin-paragraph class="line-group"/> <begin-line/><verse-num begin-chapter="9">1</verse-num>The burden of the word of the <span class="divine-name">Lord</span> is against the land of Hadrach<end-line class="br"/> <begin-line class="indent"/>and Damascus is its resting place.<end-line class="br"/> <begin-line/>For the <span class="divine-name">Lord</span> has an eye on mankind<end-line class="br"/> <begin-line class="indent"/>and on all the tribes of Israel,<footnote id="f1"> A slight emendation yields <i> For to the <span class="divine-name">Lord</span> belongs the capital of Syria and all the tribes of Israel </i> </footnote><end-line class="br"/> </verse-unit> I used visual studio to generate a schema from this and used XSD.EXE to generate classes that I can use to deserialize this mess into programmable stuff. I got everything to work and it is deserialized perfectly (almost). The problem I have is with the random text mixed throughout the child nodes. The generated verse-unit objects gives me a list of objects (begin-line, begin-block-indent, etc), and also another list of string objects that represent the bits of string throughout the xml. Here is my schema <xs:element maxOccurs="unbounded" name="verse-unit"> <xs:complexType mixed="true"> <xs:sequence> <xs:choice maxOccurs="unbounded"> <xs:element name="marker"> <xs:complexType> <xs:attribute name="class" type="xs:string" use="required" /> <xs:attribute name="mid" type="xs:string" use="required" /> </xs:complexType> </xs:element> <xs:element name="begin-chapter"> <xs:complexType> <xs:attribute name="num" type="xs:unsignedByte" use="required" /> </xs:complexType> </xs:element> <xs:element name="heading"> <xs:complexType mixed="true"> <xs:sequence minOccurs="0"> <xs:element name="span"> <xs:complexType> <xs:simpleContent> <xs:extension base="xs:string"> <xs:attribute name="class" type="xs:string" use="required" /> </xs:extension> </xs:simpleContent> </xs:complexType> </xs:element> </xs:sequence> </xs:complexType> </xs:element> <xs:element name="begin-block-indent" /> <xs:element name="begin-paragraph"> <xs:complexType> <xs:attribute name="class" type="xs:string" use="required" /> </xs:complexType> </xs:element> <xs:element name="begin-line"> <xs:complexType> <xs:attribute name="class" type="xs:string" use="optional" /> </xs:complexType> </xs:element> <xs:element name="verse-num"> <xs:complexType> <xs:simpleContent> <xs:extension base="xs:unsignedByte"> <xs:attribute name="begin-chapter" type="xs:unsignedByte" use="optional" /> </xs:extension> </xs:simpleContent> </xs:complexType> </xs:element> <xs:element name="end-line"> <xs:complexType> <xs:attribute name="class" type="xs:string" use="optional" /> </xs:complexType> </xs:element> <xs:element name="end-paragraph" /> <xs:element name="end-block-indent" /> <xs:element name="end-chapter" /> </xs:choice> </xs:sequence> <xs:attribute name="unit-id" type="xs:unsignedInt" use="required" /> </xs:complexType> </xs:element> WHAT I NEED IS THIS. I need the random text that is NOT surrounded by an xml node to be represented by an object so I know the order that everything is in. I know this is complicated, so let me try to simplify it. <field name="test_field_0"> Some text I'm sure you don't want. <subfield>Some text.</subfield> More text you don't want. </field> I need the xsd to generate a field object with items that can have either a text object, or a subfield object. I need to no where the random text is within the child nodes.

• FluentNhibernate dynamic runtime mappings.

  - by Paul Knopf

  I am building a framework where people will be able to save items that the created by inheriting a class of mine. I will be iterating over every type in the appdomain to find classes that I want to map to nhibernate. Every class that I find will be a subclass of the inherited type. I know how to create sub types in FluentNhibernate, but every sub type requires its own ClassMap class. Since I won't know these untill runtime, there is no way I can do that. Is there a way that I can add mappings to fluent nhibernate? Note, I know this is possible without fluent nhibernate using the Cfg class, but I don't want to manage the same code two different ways.

• jQuery: If user clicks out of div

  - by Paul Knopf

  I am creating a popup in query. All is well with the popup on hover. I made it see a timer starts when user's mouse leaves the div to close it. If he enters the div again before the timer is done, then the timer is cleared. This is fine, but what if a user clicks out of the div? I want that to also close the div. The only problem is that I don't want to attach click events to the wrapper on the page (because it includes the popout menu). I have seen techniques that wraps entire screen with a transparent div, and then attach a click event to hit. Although this may work, it confuses the user if he clicks the hidden div intending to click a link. He will have to click the link twice. Once two close the div (hiding the link), and another time to actually click think. Also, you loose in mouse cursors attached to any masked elements on the page (such as links cursor pointer, etc). There has to be a way to check if the user clicked out of the div without a modal and without attaching events to the entire page (page wrappers and child elements included). onclicksomewhereelse="closeme();" lol.

• How did My Object Get into ASP.NET Page State?

  - by Paul Knopf

  I know what this error is, how to fix it, etc. My question is that I don't know why my current page I am developing is throwing this error when I am not using the foo class directly in any way, nor am I setting anything to the viewstate. I am using postbacks alot, but like I said, I am not storing anything in the viewstate etc one integer. I am using nhibernate if that is relevant. Any idea why I need to mark this classes as serializable that arent being used? Where should I start investigating?

• OpenSocial and its usages

  - by Paul Knopf

  I have looked for some explanation on the exact usages for the set of standards known as OpenSocial. I need some clarification if I can use OpenSocial like the following. I would like to create one library used to community with an OpenSocial api for use in my website that will not 'behave' like an application described by common sites like facebook and myspace. I'm not making a myspace of facebook application, I'm creating my own website and I want users to be able to find friends. I would like to allow users to store usernames and passwords for various OpenSocial-supported social networks. I would also like to use the api to sync events from my web site to their specified social network. I would also like to allow my users to view a list of friends and invite them. Is it possible to create one library that supports OpenSocial and simple "point" to and social network that supports it to get a list of friends and etc?
