• looking for a set union find algorithm

  - by Mig

  I have thousands of lines of 1 to 100 numbers, every line define a group of numbers and a relationship among them. I need to get the sets of related numbers. Little Example: If I have this 7 lines of data T1 T2 T3 T4 T5 T6 T1 T5 T4 T3 T4 I need a not so slow algorith to know that the sets here are: T1 T2 T6 (because T1 is related with T2 in the first line and T1 related with T6 in the line 5) T3 T4 T5 (because T5 is with T4 in line 6 and T3 is with T4 in line 7) but when you have very big sets is painfully slow to do a search of a T(x) in every big set, and do unions of sets... etc. Do you have a hint to do this in a not so brute force manner? I'm trying to do this in python. Thanks

• Garbage collection when compiling to C

  - by Jules

  What are the techniques of garbage collection when compiling a garbage collected language to C? I know of two: maintain a shadow stack that saves all roots explicitly in a data structure use a conservative garbage collector like Boehm's The first technique is slow, because you have to maintain the shadow stack. Potentially every time a function is called, you need to save the local variables in a data structure. The second technique is also slow, and inherently does not reclaim all garbage because of using a conservative garbage collector. My question is: what is the state of the art of garbage collection when compiling to C. Note that I do not mean a convenient way to do garbage collection when programming in C (this is the goal of Boehm's garbage collector), just a way to do garbage collection when compiling to C.

• Loading a DB table into nested dictionaries in Python

  - by Hossein

  Hi, I have a table in MySql DB which I want to load it to a dictionary in python. the table columns is as follows: id,url,tag,tagCount tagCount is the number of times that a tag has been repeated for a certain url. So in that case I need a nested dictionary, in other words a dictionary of dictionary, to load this table. Because each url have several tags for which there are different tagCounts.the code that I used is this:( the whole table is about 22,000 records ) cursor.execute( ''' SELECT url,tag,tagCount FROM wtp ''') urlTagCount = cursor.fetchall() d = defaultdict(defaultdict) for url,tag,tagCount in urlTagCount: d[url][tag]=tagCount print d first of all I want to know if this is correct.. and if it is why it takes so much time? Is there any faster solutions? I am loading this table into memory to have fast access to get rid of the hassle of slow database operations, but with this slow speed it has become a bottleneck itself, it is even much slower than DB access. and anyone help? thanks

• What's the fastest way to scrape a lot of pages in php?

  - by Yegor

  I have a data aggregator that relies on scraping several sites, and indexing their information in a way that is searchable to the user. I need to be able to scrape a vast number of pages, daily, and I have ran into problems using simple curl requests, that are fairly slow when executed in rapid sequence for a long time (the scraper runs 24/7 basically). Running a multi curl request in a simple while loop is fairly slow. I speeded it up by doing individual curl requests in a background process, which works faster, but sooner or later the slower requests start piling up, which ends up crashing the server. Are there more efficient ways of scraping data? perhaps command line curl?

• Faster way to update 250k rows with SQL

  - by pablo

  I need to update about 250k rows on a table and each field to update will have a different value depending on the row itself (not calculated based on the row id or the key but externally). I tried with a parametrized query but it turns out to be slow (I still can try with a table-value parameter, SqlDbType.Structured, in SQL Server 2008, but I'd like to have a general way to do it on several databases including MySql, Oracle and Firebird). Making a huge concat of individual updates is also slow. What about creating a temp table and running an update joining my table and the tmp one? Will it work faster?

• C++: Most common way to talk to one application from the other one

  - by MInner

  In bare outlines, I've got an application which looks through the directories at startup and creates special files' index - after that it works like daemon. The other application creates such 'special' files and places them in some directory. What way of informing the first application about a new file (to index it) is the most common, simple (the first one is run-time, so it shouldn't slow it too much), and cross-platform if it is possible? I've looked through RPC and IPC but they are too heavy (also non-cross-platform and slow (need a lot of features to work - I need a simple light well-working way), probably).

• JQUERY, div with a fixed height (with a scrollbar) how to animate until it grows to no longer need a

  - by nobosh

  JQUERY, div with a fixed height (with a scrollbar) how to animate until it grows to no longer need a scroll bar? I have a div on a page with a CSS height:200px setting, which makes the DIV have a vertical scroll bar, which allows the user to scroll through a bunch of text. I would like to animate the DIV to expand in height until all content in the div is shown, meaning no more scroll bar I tried the following: $("#view-container").animate({"height": "auto"}, "slow"); but that didn't work while this does: $("#view-container").animate({"height": "1000px"}, "slow"); problem with that is the text size in the DIV is variable. Ideas? Thanks

• Is C++ Unmanaged?

  - by Chris Becke

  Am I the only one bugged by the phrase "unmanaged c++"? I think the phrase is implicitly insulting, and is designed to be so. Stroustrup never wrote "The Design and Evolution of Unmanaged C++" and the not unmanaged C++ standards committee is not working on "UC++1x". Maybe I should disingeneously invent a suite of languages called "Faster" purely so I can refer to any language I want to implicitly denigrate with a "Slow" prefix. "Oh, youre using Slow CSharp? Shame!"

• load search results into a div jquery and rails

  - by odpogn

  In my rails app I have a search bar where users can search other users. Currently when a User submits the search from, they're redirected to a "results" page. I want to load those results in a div on the same page.. I was able to do this with my websites navigation links, but I'm pretty new to jQuery and rails and can't figure this one out... my jQuery corresponding to my navigation links: $(function() { $('#links a').live('click', function() { $('#pages').load(this.href).fadeIn('slow'); return false; }); }); my attempt to do the same with my search function... $(function() { $('#search').submit(function() { $('#pages').load(this.href).fadeIn('slow'); }); }); any help would be much appreciated~ along with some useful jQuery tutorials for a newbie!!

• What performance indicators can I use to convince management that I need my development PC upgraded?

  - by Aaron Daniels

  At work, my PC is slow. I feel that I can be way more productive if I just wasn't waiting for Visual Studio and everything else to respond. My PC isn't bad (dual-core, 3GB of RAM), but there is a lot of corporate software and whatnot to slow everything down and sometimes lock it up. Now, some developers have begun getting Windows 7 machines with 8 GB of RAM. Of course, I start salivating at this. However, I was told that I "had to justify" why I should get a new machine. I can think of a lot of different things, but I am curious as to what every one else on SO would have to say. NOTE: Ideally, these reasons should be specifically related to .NET development in Visual Studio on a Windows machine. This isn't a "how can I make my machine faster" question.

• Annoying Bug in banner cycle

  - by Davemof

  I have created a rotating banner script for a new site I'm developing View banner here(it rotates every 10 seconds) Unfortunately to the transition seems to be a biut buggy, and the image will fade out, show the same image again and then fade in the new one. I think I have made a simple error somewhere, but can't figure out where it is. the code used to cycle the banners is: In document ready: if ($('.home').length > 0){ $('<img width="100%" />').attr('src', '/assets/img/backgrounds/home/hero'+homecount+'.jpg').load(function(){ $('.hero').append( $(this) ); $('.hero img').fadeIn('medium').delay(10000).fadeOut('slow', loopImages); setHeroHeight(); }); } Outside document ready: function loopImages(){ homecount = homecount+1; if (homecount > 5){ homecount = 1; } $('.hero img') .attr('src', '/assets/img/backgrounds/home/hero'+homecount+'.jpg') .load(function(){ $('.hero img').fadeIn('fast')}).delay(10000).fadeOut('slow', loopImages); } Any help would be greatly appreciated Thanks Dave

• SQL Native Client 10 Performance miserable (due to server-side cursors)

  - by namezero

  we have an application that uses ODBC via CDatabase/CRecordset in MFC (VS2010). We have two backends implemented. MSSQL and MySQL. Now, when we use MSSQL (with the Native Client 10.0), retrieving records with SELECT is dramatically slow via slow links (VPN, for example). The MySQL ODBC driver does not exhibit this nasty behavior. For example: CRecordset r(&m_db); r.Open(CRecordset::snapshot, L"SELECT a.something, b.sthelse FROM TableA AS a LEFT JOIN TableB AS b ON a.ID=b.Ref"); r.MoveFirst(); while(!r.IsEOF()) { // Retrieve CString strData; crs.GetFieldValue(L"a.something", strData); crs.MoveNext(); } Now, with the MySQL driver, everything runs as it should. The query is returned, and everything is lightning fast. However, with the MSSQL Native Client, things slow down, because on every MoveNext(), the driver communicates with the server. I think it is due to server-side cursors, but I didn't find a way to disable them. I have tried using: ::SQLSetConnectAttr(m_db.m_hdbc, SQL_ATTR_ODBC_CURSORS, SQL_CUR_USE_ODBC, SQL_IS_INTEGER); But this didn't help either. There are still long-running exec's to sp_cursorfetch() et al in SQL Profiler. I have also tried a small reference project with SQLAPI and bulk fetch, but that hangs in FetchNext() for a long time, too (even if there is only one record in the resultset). This however only happens on queries with LEFT JOINS, table-valued functions, etc. Note that the query doesn't take that long - executing the same SQL via SQL Studio over the same connection returns in a reasonable time. Question1: Is is possible to somehow get the native client to "cache" all results locally use local cursors in a similar fashion as the MySQL driver seems to do it? Maybe this is the wrong approach altogether, but I'm not sure how else to do this. All we want is to retrieve all data at once from a SELECT, then never talk the server again until the next query. We don't care about recordset updates, deletes, etc or any of that nonsense. We only want to retrieve data. We take that recordset, get all the data, and delete it. Question2: Is there a more efficient way to just retrieve data in MFC with ODBC?

• Global variables that can be used in multiple jQuery functions

  - by YouBook

  Can you be able to contain variables that can be used in multiple functions in jQuery, example: var self = $(this); var box = self.parents('.box'); $('#title').click(function() { self.css('background', 'red'); box.slideDown('slow'); }).dblclick(function() { self.css('background', 'green'); box.slideUp('slow'); }); So that self and box can be used within these event functions so I don't have to keep doing this: $('#title').click(function() { var self = $(this); var box = self.parents('.box'); self.css('background', 'red'); }).dblclick(function() { var self = $(this); var box = self.parents('.box'); self.css('background', 'green'); }); But question is, is it possible, if so, how can you do that?

• Add view overlay to iPhone app

  - by Rob Lourens

  I'm trying to do something like this: - (void)sectionChanged:(id)sender { [self.view addSubview:loadingView]; // Something slow [loadingView removeFromSuperview]; } where loadingView is a semi-transparent view with a UIActivityIndicatorView. However, it seems like added subview changes don't take effect until the end of this method, so the view is removed before it becomes visible. If I remove the removeFromSuperview statement, the view shows up properly after the slow processing is done and is never removed. Is there any way to get around this?

• Would it be simply better to use the system's functions rather than use the language?

  - by Nullw0rm

  There are many scenarios where I've questioned PHP's performance with some of its functions, and whether I should build a complex class to handle specific things using its seemingly slow tools. For example, Complex regular expressions with sed and processing with awk would seemingly be exponential in performance rather than making PHP's regular expression and seemingly excessive functions parse and in time manage to finish it. If I were to do a lot of network tasks such as MX lookups/DIGging/retrieving simultaneously I would rather pass it via system() and let the OS handle it itself. There are simply too many functions in PHP, that are inefficient and result in slow pages or can be handled easier by the OS. What are your opinions? Do you think I should do the hard work with the OS in its own/custom functions?

• Paging a UIScrollView with a large PDF

I tried the following options: Convert all the PDF pages to UIImages at startup, this works, but is very slow on start Manually drawing the PDF page in the drawRect, but yet again this was slow... And I prefer not to load everything at startup but to do it during the usage. Did anyone did this recently? Can't seem to find a nice example project. Thnx! Jelle

• Outlook Macro to Search

  - by Corpa Loom

  What's the best way to automate this function? I want to be able to do this in Outlook 2010, (1)select a specific mail account (2)Key in a folder that I am looking for (3)Then have the macro/program fire off an "*" asterisk (4)Then insert the text that I keyed in step one. I am trying to automate the search for a folder hot-keys that already exist. My problem is that I can't type the folder that I am looking for fast enough and all the search programs that I have used are far too slow. The hot-key search is awesome and super fast, I just can't type the folder that I am looking for fast enough. Can this process be automated? And I can't use this code, it is far too slow: http://www.vboffice.net/sample.html?mnu=2&smp=82&cmd=showitem&lang=en

• Jquery toggle with two elements

  - by Jesse

  I am using a toggle on a graphic to slide out a contact form. The problem is, the contact form can cover up the graphic element on low resolutions. I thought a solution would be to include a "close this" inside the form, that would use the same toggle effect. When I add the close this element to the code, instead of working in tandem with the original graphic element, it starts the chain back over, and slides the contact form even further out. Site is here: http://www.tritonloyaltysupport.com/status Code for toggle here: $(this).html(div_form); //show / hide function $('div.contactable').toggle( function() { $('#overlay').css({display: 'block'}); $('#contactForm').animate({"marginRight": "-=0px"}, "fast"); $('#contactForm').animate({"marginRight": "+=390px"}, "slow"); }, function() { $('#contactForm').animate({"marginRight": "-=390px"}, "slow"); $('#overlay').css({display: 'none'}); } );

• 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?

• Looking for a source code management system with a good GUI client

  - by Anders Öhrt

  We are currently using CS-RCS Pro for source code management, and are looking for to replace this due to performance issues. It is based on client side file access with no own protocol, which makes it painfully slow to use over a slow VPN line since it always rewrites the whole history of a file. It does however have a GUI client which is very simple and gives a great overview. We have three main requirements in a SCM: Fast. It must have a server side service or some other smart way so working with files with a large history is fast. A good Windows GUI client (not Explorer shell integration, not VS or Eclipse IDE integration), so working with files and branches is easy. The possibility to have several branches checked out at once in different directories. Does anyone have a recommendation of a SCM which fulfills there requirements?
