• When using a HiLo ID generation strategy, what types should be used to hold Ids?

  - by UpTheCreek

  I'm asking this from a c#/NHibnernate perspective, but it's generally applicable. The concern is that the HiLo strategy goes though id's pretty quickly, and for example a low record-count table (Such as Users) is sharing from the same set of id's as a high record-count table (Such as comments). So you can potentially get to high numbers quicker that with other strategies. So what do people recommend? Code side: int/uint/long/ulong? DBSide: int/bigint? My feeling is to go with longs and bigingts, but would like a sanity check :)

• PHP - Resize an image and fill gaps of proportions with a color

  - by Kerry

  I am uploading logos to my system, and they need to fix in a 60x60 pixel box. I have all the code to resize it proportionately, and that's not a problem. My 454x292px image becomes 60x38. The thing is, I need the picture to be 60x60, meaning I want to pad the top and bottom with white each (I can fill the rectangle with the color). The theory is I create a white rectangle, 60x60, then I copy the image and resize it to 60x38 and put it in my white rectangle, starting 11px from the top (which adds up to the 22px of total padding that I need. I would post my code but it's decently long, though I can if requested. Does anyone know how to do this or can you point me to code/tutorial that does this?

• How does Gmail do comet on Opera?

  - by Unknown

  I would like to know how Gmail (or anyone else) does comet on Opera. Here is what I know so far from my experiments. It doesn't use the event-source tag which is broken in Opera 10.51. It doesn't use iframe which displays a spinning throbber and a busy mouse cursor. It doesn't use responseText on xmlhttprequest when readyState = 3 which is known to be broken on Opera. I tried seeing how it was done in mibbit and etherpad, and I found that they both use long-polling.

• filtering elements from list of lists in Python?

  - by user248237

  I want to filter elements from a list of lists, and iterate over the elements of each element using a lambda. For example, given the list: a = [[1,2,3],[4,5,6]] suppose that I want to keep only elements where the sum of the list is greater than N. I tried writing: filter(lambda x, y, z: x + y + z >= N, a) but I get the error: <lambda>() takes exactly 3 arguments (1 given) How can I iterate while assigning values of each element to x, y, and z? Something like zip, but for arbitrarily long lists. thanks, p.s. I know I can write this using: filter(lambda x: sum(x)..., a) but that's not the point, imagine that these were not numbers but arbitrary elements and I wanted to assign their values to variable names.

• GroupLayout giving error with java swing

  I am getting some long list of error .

• Building html tables from query data... faster?

  - by Andrew Heath

  With my limited experience/knowledge I am using the following structure to generate HTML tables on the fly from MySQL queries: $c = 0; $t = count($results); $table = '<table>'; while ($c < $t) { $table .= "<tr><td>$results[0]</td><td>$results[1]</td> (etc etc) </tr>"; ++$c; } $table .= '</table>'; this works, obviously. But for tables with 300+ rows there is a noticeable delay in pageload while the script builds the table. Currently the maximum results list is only about 1,100 rows, and the wait isn't long, but there's clearly a wait. Are there other methods for outputting an HTML table that are faster than my WHILE loop? (PHP only please...)

• passing structure directly to function

  - by ra170

  I have a struct that I initialize like this: typedef struct { word w; long v; } MyStruct; MyStruct sx = {0,0}; Update(sx); Now, it seems such a waste to first declare it and then to pass it. I know that in C#, there's a way to do everything in one line. Is there any possiblity of passing it in a more clever (read: cleaner) way to my update function?

• Poco C++ library on OSX 10.8.2: Undefined symbols for architecture x86_64

  - by Arman

  I'm trying to use Poco C++ library to do the simple http requests in C++ on Mac OS X 10.8.2. I installed Poco, copy-pasted the http_request.cc code from this tutorial, ran it with 'g++ -o http_get http_get.cc -lPocoNet', but got: Undefined symbols for architecture x86_64: "Poco::StreamCopier::copyStream(std::basic_istream<char, std::char_traits<char> >&, std::basic_ostream<char, std::char_traits<char> >&, unsigned long)", referenced from: _main in ccKuZb1g.o "Poco::URI::URI(char const*)", referenced from: _main in ccKuZb1g.o "Poco::URI::~URI()", referenced from: _main in ccKuZb1g.o "Poco::URI::getPathAndQuery() const", referenced from: _main in ccKuZb1g.o "Poco::URI::getPort() const", referenced from: _main in ccKuZb1g.o "Poco::Exception::displayText() const", referenced from: _main in ccKuZb1g.o "typeinfo for Poco::Exception", referenced from: GCC_except_table1 in ccKuZb1g.o ld: symbol(s) not found for architecture x86_64 collect2: ld returned 1 exit status Have been struggling with this for couple of hours. Any idea how to fix this? Thanks in advance!

• How should I call the operation that limit a string's length?

  - by egarcia

  This is a language-agnostic question - unless you count English as a language. I've got this list of items which can have very long names. For aesthetic purposes, these names must be made shorter in some cases, adding dots (...) to indicate that the name is longer. So for example, if article.name returns this: lorem ipsum dolor sit amet I'd like to get this other output. lorem ipsum dolor ... I can program this quite easily. My question is: how should I call that shortening operation? I mean the name, not the implementation. Is there a standard English name for it?

• getItemIdAtPosition() problem in Android?

  - by Praveen Chandrasekaran

  I am using the getItemIdAtPosition() to get the Basecoulmns id of the record in Sqlite Database. the code is below: protected void onListItemClick(ListView l, View v, int position, long id) { Cursor cursor = managedQuery(Constants.CONTENT_URI, PROJECTION, BaseColumns._ID + "=" + l.getItemIdAtPosition(position), null, null); } But its does not retrieves the id correctly. Is this method depends some thing at the time of setting adapter or creation of DB? I have no idea. why it shows the position of the listview. Any Idea?

• Problem with dictionary key in Python

  - by Hossein

  Hi all, For some project I have to make a dictionary in which the keys are urls,among which I have this url: http://www.microsoft.com/isapi/redir.dll prd=windows&sbp=mediaplayer&ar=Media&sba=Guide&pver=6.2 the url is too long to fit in here I guess in one single line. there is a space between .dll and prd. I can build a dictionary without any errors this url is also a key. but for some reason when I want to extract the values associated to this key(url). I cannot, I get and error "error key:...." Does someone know what is wrong with this url? Are dictionary keys sensitive to some stuff? thanks

• Have you ever turned-down morally questionable or unethical web work?

  - by louism

  i'm just wondering if you guys have ever had a situation where you were offered a web development project which you turned down because you felt it was unethical or morally questionable. i've only had this once. i was offered a contract to develop a website for a meat abattoir (i.e. slaughterhouse). what's the problem you may ask? i'm vegetarian. i know, it's not an egregious dilemma, but it just didn't seem right to me. i have a female graphic designer friend who declined to work on a sex toys website where she was working at the time. funny thing is, it wouldn't bother me to work on a porn site (as long as it wasn't anything shifty - e.g. dwarfs + donkeys, that sort of thing). anyone else ever had a similar experience?

• Incremement Page Hit Count in Django

  - by Andrew C

  I have a table with an IntegerField (hit_count), and when a page is visited (ie. http://site/page/3) I want record id 3 'hit_count' column in the database to increment by 1. The query should be like: update table set hit_count = hit_count + 1 where id=3 Can I do this with the standard Django Model conventions? Or should I just write the query by hand? I'm starting a new project, so I am trying to avoid hacks. We'll see how long this lasts! Thanks!

• Accessing parent 'this' inside a jQuery $.getJSON

  - by JP

  I'm going to assume that the overall structure of my code as it currently stands is 'best', otherwise this question gets too long, but if I've made any obvious mistakes (or if I've made life hard for myself) then please correct away! Using jQuery, I have a javascript 'class' set out something like this: function MyClass () { this.noise = "Woof" this.dostuff = function() { $.getJSON("http://cows.go",function(moo) { this.noise = moo.inEnglish; } } } var instance = new MyClass(); instance.doStuff() console.log(instance.noise) I'm expecting some kinda tea drinking moo in the console, but of course I'm getting an error about this.noise not being defined (because $.getJSON doesn't pass this through, right?) Any suggestions as to how to be able to affect instance.squeak for any and all instances of MyClass without interference?

• Make a usable Join relationship with LINQ on top of a database CSV design error

  - by jdk

  I'm looking for a way to fix and/or abstract away a comma-separated values (CSV) list in a database field in order to reconstruct a usable relationship such that I can properly join the two tables below and query them using LINQ and its Join method. Following is a sample showing the Person table and CsvArticleIds field having a CSV value to represent a one-to-many association with Article records. TABLE [dbo].[Person] Id Name CsvArticleIds -- ---------- -------- 1 Joe "15,22" 5 Ed "22" 10 Arnie "8,15,22" ^^^(Of course a link table should have been created; nonetheless the relationship with articles is trapped inside that list of CSV values.) TABLE [dbo].[Article] Id Title -- ---------- 8 Beginning C# 15 A Historic look at Programming in the 90s 22 Gardening in January Additional Info the fix can be at any level: C#.NET or SQL Server something easy because I will be repeating the solution for many other CSV values in other tables. Elegant is nice too. not looking for efficiency because this is part of a one-time data migration task and can take as long as it wants to run.

• C inline assembly of x96 fbstp instruction

  - by David HUnter

  Was wondering how to inline a usage of fbstp on a 32 bit I86 architecture. I tried something like int main( ) { double foo = 100.0; long bar = 0; asm( "pushl %1; fbstp %0" : "=m"(bar) : "r"(foo) ); ... But bar is unchanged. I have tried reading everything I can find on this but most example simply do things like add two integers together. I can’t find any that talk about pushing operands onto the stack and what I should be doing when an instruction like fbstp writes 80 bits of data back to memory ( i.e. what C type to use ) and how to specify it in the asm syntax. Also on x86-64 there seems to be a pushq and no pushl but fbstp still exists whereas fbstq does not. Is there some other magic for 64 bit.

  - by Jeeka

  I am writing a Midlet(using Netbeans) which reads a file containing exactly 2400 lines (each line being 32 characters long) and (extract a part of each line) puts them in an array. I am doing the same for 11 such files( all files have exactly 2400 lines).The Midlet runs fine for reading 6 files and putting them in 6 arrays. However, the Midlet stops while doing it for the 7th file throwing the following exception: TRACE: , startApp threw an Exception java.lang.OutOfMemoryError (stack trace incomplete) java.lang.OutOfMemoryError (stack trace incomplete) I have tried the modifying the netbeans.conf file to increase the heap memory ( as suggested by many forums and blogs) but nothing works for me.

• How does one advance in programming?

  - by Joe Barr

  I really have the felling as if I'm stuck in my own craft. I've been developing and learning for a while now and keep having the feeling that I should advance more, or even be more knowledgeable. I've started projects I didn't finish because I thought I lacked the knowledge and the skill to make that feature work just right, or to make that code magically appear on my screen. I've read books I didn't finish, thinking I wasn't advanced enough for the subjects they covered. I've been around long enough to know that everything comes with experience, hard work and dedication. Having said this, I just want to be able to work without getting stuck on a particular problem that involves my cluelessness of a language or a tool feature. My question to you would be, how does one advance in programming? What are the secrets (if any) to advance to the point of fluency in a particular language or a task. Thank you!

• slow record deletion with large ntext values

  - by asking

  I'm having trouble deleting some records via a stored procedure from a table in SQLServer 2008R2 that has ntext columns. The stored proc is timing out and running the query directly takes a very long time. The initial query was a straight "delete from y where x = z" and I've also tried running it in batches of 1000 with transactions but it is still slow and timing out in a stored proc. The majority of the records in the table will not be deleted each time (it's not just a once-off query but will be run other times). The ntext columns are not used in the where clause and I can't change the column types. Any suggestions on the quickest way to delete records with large ntext values? Thanks

• Bulletproof way to DROP and CREATE a database under Continuous Integration.

  - by H. Abraham Chavez

  I am attempting to drop and recreate a database from my CI setup. But I'm finding it difficult to automate the dropping and creation of the database, which is to be expected given the complexities of the db being in use. Sometimes the process hangs, errors out with "db is currently in use" or just takes too long. I don't care if the db is in use, I want to kill it and create it again. Does some one have a straight shot method to do this? alternatively does anyone have experience dropping all objects in the db instead of dropping the db itself? USE master --Create a database IF EXISTS(SELECT name FROM sys.databases WHERE name = 'mydb') BEGIN ALTER DATABASE mydb SET SINGLE_USER --or RESTRICTED_USER --WITH ROLLBACK IMMEDIATE DROP DATABASE uAbraham_MapSifterAuthority END CREATE DATABASE mydb;

• Delete text from copied text

  - by riddle

  Hello, I would to use JavaScript to clean up text that’s being copied from my site. I use snippets like this: body { vertical-align: middle; ? } Where ? indicates comment later on. I want readers to copy this snippet and use it – so I need to delete that Unicode marker. How can I access text that’s being copied and make changes to it? I considered deleting marker(s) from snippet when user clicks (mousedown) on it, so she could select the text, copy it and then I would restore markers but it seems a really long way to do it.

• fread() behaves weird

  - by Cres

  hi, I have a problem in a C program of mine where after I use fread(), the file pointer goes to the end of the file sometimes. I'll try to explain better - the code looks something like: dummy = ftell(fp); fread(&buf, sizeof(unsigned char), 8, fp); dummy = ftell(fp); where fp is a file pointer to an opened file (opened it with "w+", I'm using it as a binary file and I know i'm supposed to have a "b" in there too, but I heard its not really important to add it..), dummy is just an unsigned long variable, and buf is unsigned char[8] now, when debugging, at the ftell before the fread, dummy is 262062 at the ftell after the fread, dummy is 262640 even though I only 'moved' 8 bytes.. does anyone have any idea what can be the cause of this..? thanks for your help :)

• Clojure closures and GC

  - by Ralph

  It is my understanding that the default ClassLoader used in Java (and thus, Clojure) holds on to pointers to any anonymous classes created, and thus, onto lambdas and closures. These are never garbage collected, and so represent a "memory leak". There is some investigation going on for Java 7 or 8 to adding an anonymous ClassLoader that will not retain references to these functions. In the mean time how are people dealing with writing long-running applications in languages like Clojure and Scala, that encourage the use of these constructs? Is there any possibility that Clojure could provide its own anonymous ClassLoader, extending the system one, but not holding onto created classes?
