• z-index problem in IE6

  - by simonkagwe

  I have been struggling with a z-index problem in IE6 for quite some time now. I require part of the 'header' portion in my website to open up (using jQuery), and cover a portion of the 'content' section which comes after it. The thing works like a charm on all the browsers I've tested it on (Firefox, Chrome, Opera), but IE6 instead pushes down the content section, which is not what I want. The website itself is here I have done extensive research both here on SO and thro Google but all the workarounds I've found don't work for my case. Please help.

• cakephp filter index pages according to foreign keys

  - by Marki

  Hi there, I'm pretty new to CakePHP and was missing a crucial feature not generated as scaffold: filtering. What do I have to do to provide dropdowns or multi-selects on the index pages for each field that is a (foreign) key, thereby allowing to filter the table ("OR" inside multi-select, "AND" between different multi-selects, if any)? From what my websearch has shown me there are many more people trying to accomplish the same thing, although I couldn't find anything that would work for me because either they have text fields and do wildcard filtering, or the plugins they propose only work for 1.2 whereas i now started with 1.3 etc. etc. Can someone alleviate the confusion and maybe present some working code or direct me to the definitive guide[tm] where this matter has been solved? Thx

• javascript increment index in funciton

  - by mcgrailm

  I'm just trying to figure out how to create an index inside a function so I can keep track of the items its generating and I'm not sure how to do this seems like I should know this.. addLocation(options,location) funciton addLocation(options,location){ $('#list').append('<li class="location"><div>'+location.label+'</div>'+ '<input type="hidden" name="location['+x+'][lat]" value="'+location.lat+'" />'+ '<input type="hidden" name="location['+x+'][lon]" value="'+location.lon+'" />'+ '<input type="hidden" name="location['+x+'][loc]" value="'+location.loc+'" />'+ '<input type="hidden" name="location['+x+'][label]" value="'+location.label+'" />'+ '</li>'); } now normally you have a forloop to help you keep track of things but int this instance I'm not appending items in a loop and I keep getting an error saying x in undefined appreciate any help you can give thanks Mike

• need more complex index !

  - by silversky

  I'm sorry if it's not an appropriate question for this site, and if it's necesary I'll close this question. But maybe someone could give me an ideea: I'm trying to find a more complex index to make an hierarchy. For example: 5 votes from 6 = 83% AND 500 votes from 600 = 83%; 10 votes from 600 = 1.66% If I make a hierarchy with the %, first two will be on the same place, but I think that 83% from 600 it's more valuable than the first one. I could compare 5, 10, 500, but again it's not fair because the third case (10 votes) will be in front of the first case (5 votes), wich it's not fair beacuse the third case has only 1.66% Maybe someone could give me an ideea how to give more weight for the second case but in the same time let the let the new entries have a fair chance.

• MSSQL Search Proper Names Full Text Index vs LIKE + SOUNDEX

  - by Matthew Talbert

  I have a database of names of people that has (currently) 35 million rows. I need to know what is the best method for quickly searching these names. The current system (not designed by me), simply has the first and last name columns indexed and uses "LIKE" queries with the additional option of using SOUNDEX (though I'm not sure this is actually used much). Performance has always been a problem with this system, and so currently the searches are limited to 200 results (which still takes too long to run). So, I have a few questions: Does full text index work well for proper names? If so, what is the best way to query proper names? (CONTAINS, FREETEXT, etc) Is there some other system (like Lucene.net) that would be better? Just for reference, I'm using Fluent NHibernate for data access, so methods that work will with that will be preferred. I'm using MS SQL 2008 currently.

• Git index resets itself

  - by trobrock

  Every so often when I run git add . to add new files to my repo my git index will reset and think all the files in the repo have been deleted. I run these commands: git status git add . git status git commit -a -m "Commit message" everything looks fine at all those points until I commit and it says every file was deleted, all I have to do it run git add . and commit again to get the files back, but this becomes a pain. And this doesnt happen every time, maybe about 40% of the time. Anyone know why this might happen? I am on Mac OS 10.6.3 with Git 1.6.6

• Apache RewriteRule .* index.php [NC,L] Not working

  - by Daok

  I am trying to redirect everything to a single page from my /website/folder/ directory.

RewriteEngine on RewriteRule .* index.php [NC,L] When I try : http://127.0.0.1:8888/website/folder/fileDoesntExistMustGoIndex I have an "Object not found 404" error and the access.log display: 127.0.0.1 - - [13/Mar/2010:13:48:31 -0500] "GET /website/folder/fileDoesntExistMustGoIndexHTTP/1.1" 404 1118 I have check the httpd.conf and I see nothing that could alter this .htaccess statement.

• HTML: How to get a child element to show behidn (lower z-index) than its parent

  - by dclowd9901

  I need for a certain dynamic element to always appear on top of another element, no matter what order in the DOM tree they are. Is this possible? I've tried z-index (with position: relative), and it doesn't seem to work. I hate to be vague, but this is the simplest way I can think of asking this question without explaining its purpose ad nauseum. So, to recap, I need <div class="a"> <div class="b"></div> </div> <div class="b"> <div class="a"></div> </div> To display exactly the same when rendered. And for flexibility purposes (I'm planning on distributing a plugin that needs this functionality), I'd really like to not have to resort to absolute or fixed positioning.

• Create fulltext index on a VIEW

  - by kylex

  Is it possible to create a full text index on a VIEW? If so, given two columns column1 and column2 on a VIEW, what is the SQL to get this done? The reason I'd like to do this is I have two very large tables, where I need to do a FULLTEXT search of a single column on each table and combine the results. The results need to be ordered as a single unit. Suggestions? EDIT: This was my attempt at creating a UNION and ordering by each statements scoring. (SELECT a_name AS name, MATCH(a_name) AGAINST('$keyword') as ascore FROM a WHERE MATCH a_name AGAINST('$keyword')) UNION (SELECT s_name AS name,MATCH(s_name) AGAINST('$keyword') as sscore FROM s WHERE MATCH s_name AGAINST('$keyword')) ORDER BY (ascore + sscore) ASC sscore was not recognized.

• Structure accessible by attribute name or index options

  - by Bruno DeGoia

  I am very new to Python, and trying to figure out how to create an object that has values that are accessible either by attribute name, or by index. For example, the way os.stat() returns a stat_result or pwd.getpwnam() returns a struct_passwd. In trying to figure it out, I've only come across C implementations of the above types. Nothing specifically in Python. What is the Python native way to create this kind of object? I apologize if this has been widely covered already. In searching for an answer, I must be missing some fundamental concept that is excluding me from finding an answer.

• Algorithm to split an array into N groups based on item index (should be something simple)

  - by serg

  I feel that it should be something very simple and obvious but just stuck on this for the last half an hour and can't move on. All I need is to split an array of elements into N groups based on element index. For example we have an array of 30 elements [e1,e2,...e30], that has to be divided into N=3 groups like this: group1: [e1, ..., e10] group2: [e11, ..., e20] group3: [e21, ..., e30] I came up with nasty mess like this for N=3 (pseudo language, I left multiplication on 0 and 1 just for clarification): for(i=0;i<array_size;i++) { if(i>=0*(array_size/3) && i<1*(array_size/3) { print "group1"; } else if(i>=1*(array_size/3) && i<2*(array_size/3) { print "group2"; } else if(i>=2*(array_size/3) && i<3*(array_size/3) print "group3"; } } But what would be the proper general solution? Thanks.

• Microsoft SQL Server 2008 - 99% fragmentation on non-clustered, non-unique index

  - by user550441

  I have a table with several indexes (defined below). One of the indexes (IX_external_guid_3) has 99% fragmentation regardless of rebuilding/reorganizing the index. Anyone have any idea as to what might cause this, or the best way to fix it? We are using Entity Framework 4.0 to query this, the EF queries on the other indexed fields about 10x faster on average then the external_guid_3 field, however an ADO.Net query is roughly the same speed on both (though 2x slower than the EF Query to indexed fields). Table id(PK, int, not null) guid(uniqueidentifier, null, rowguid) external_guid_1(uniqueidentifier, not null) external_guid_2(uniqueidentifier, null) state(varchar(32), null) value(varchar(max), null) infoset(XML(.), null) -- usually 2-4K created_time(datetime, null) updated_time(datetime, null) external_guid_3(uniqueidentifier, not null) FK_id(FK, int, null) locking_guid(uniqueidentifer, null) locked_time(datetime, null) external_guid_4(uniqueidentifier, null) corrected_time(datetime, null) is_add(bit, not null) score(int, null) row_version(timestamp, null) Indexes PK_table(Clustered) IX_created_time(Non-Unique, Non-Clustered) IX_external_guid_1(Non-Unique, Non-Clustered) IX_guid(Non-Unique, Non-Clustered) IX_external_guid_3(Non-Unique, Non-Clustered) IX_state(Non-Unique, Non-Clustered)

  "My search returns a highlighted fragment from a field. I want to know that in that field of particular searched document, where does that fragment starts and ends ?" for instance. consider i am searching "highlighted fragment" in above lines (consider the above para as single document). I am setting my fragmenter as : SimpleFragmenter fragmenter = new SimpleFragmenter(30); now the output of GetBestFragment is somewhat like : "returns a highlighted fragment from" Is it possible to get the starting and ending index of this fragment in the text above (say starting is 10 and ending is 45)

• Question about mysql indexes on low to medium cardinality columns

  - by Kevin J

  I have a general question about the way that database indexing works, particularly in mysql. Let's say I have a table with a million rows with a column "ClientID" that is distributed relatively equally among 30 values. Thus, this column is very low cardinality (30) relative to the primary key (1 million). Now, I understand that you shouldn't create indexes on low cardinality fields. However, in this case, queries are only ever done with one of the 30 clientIDs. Thus, wouldn't creating an index on ClientID be helpful, as the search space is automatically reduced to 1/30th what it normally would be? Or is my understanding of how the index works flawed? Thanks

• Google App Engine Database Index

  - by fjsj

  I need to store a undirected graph in a Google App Engine database. For optimization purposes, I am thinking to use database indexes. Using Google App Engine, is there any way to define the columns of a database table to create its index? I will need some optimization, since my app uses this stored undirected graph on a content-based filtering for item recommendation. Also, the recommender algorithm updates the weights of some graph's edges. If it is not possible to use database indexes, please suggest another method to reduce query time for the graph table. I believe my algorithm does more data retrieval operations from graph table than write operations. PS: I am using Python.

Normally, I would use the in-reply-to field or references field, but I recently found that Blackberrys do NOT include these fields. The only include Thread-Index field.

• Multiple indexes for a Java Collection - most basic solution?

  - by chris_l

  Hi, I'm looking for the most basic solution to create multiple indexes on a Java Collection. Required functionality: When a Value is removed, all index entries associated with that value must be removed. Index lookup must be faster than linear search (at least as fast as a TreeMap). Side conditions: It should ideally work with JavaSE (6.0) alone - no extra libraries, if possible. If necessary, then only small (not something like Lucene), common and well tested libraries. No database! Of course, I could write a class that manages multiple Maps myself. But I'd like to know, if it can be done without - while still getting a simple usage similar to using a single indexed java.util.Map. Thanks, Chris

• Odd problem with IE8 and z-index CSS property

  - by DK39

  I not been able to put one DIV over his parent DIV in Internet Explorer. With Firefox is working as suposed to. The odd part is that if I open the html file directly in IE, everything works fine. But if I upload to the server and open from there, the div is hidden underneath his parent. I've tried several z-index combinations and none works.

• Indexes and multi column primary keys

  - by David Jenings

  Went searching and didn't find the answer to this specific noob question. My apologies if I missed it. In a MySQL database I have a table with the following primary key PRIMARY KEY id (invoice, item) In my application I will also frequently be selecting on "item" by itself and less frequently on only "invoice". I'm assuming I would benefit from indexes on these columns. MySQL does not complain when I define the following: INDEX (invoice), INDEX (item), PRIMARY KEY id (invoice, item) But I don't see any evidence (using DESCRIBE -- the only way I know how to look) that separate indexes have been established for these two columns. So the question is, are the columns that make up a primary key automatically indexed individually? Also, is there a better way than DESCRIBE to explore the structure of my table?

Is there a file I could just include that includes the rest for me? If I just include the index.php it dispatches the call which I don't want. Regards Nicklas

• Display another field in the referenced table for multiple columns with performance issues in mind

  I have a table of edge like this: ------------------------------- | id | arg1 | relation | arg2 | ------------------------------- | 1 | 1 | 3 | 4 | ------------------------------- | 2 | 2 | 6 | 5 | ------------------------------- where arg1, relation and arg2 reference to the ids of objects in another object table: -------------------- | id | object_name | -------------------- | 1 | book | -------------------- | 2 | pen | -------------------- | 3 | on | -------------------- | 4 | table | -------------------- | 5 | bag | -------------------- | 6 | in | -------------------- What I want to do is that, considering performance issues (a very big table more than 50 million of entries) display the object_name for each edge entry rather than id such as: --------------------------- | arg1 | relation | arg2 | --------------------------- | book | on | table | --------------------------- | pen | in | bag | --------------------------- What is the best select query to do this? Also, I am open to suggestions for optimizing the query - adding more index on the tables etc... EDIT: Based on the comments below: 1) @Craig Ringer: PostgreSQL version: 8.4.13 and only index is id for both tables. 2) @andrefsp: edge is almost x2 times bigger than object.
