• Just seen a factory style object creating in JavaScript (without literals). What else do I need to k

  - by alex

  I have just seen this in code var thisYear = (new Date()).getFullYear(); See it live on JSbin. This is cool, as I've always done something like that in 2 lines, i.e. create the new object instance and assigned it to a variable, then called the method on it. Is this new method fine to use everywhere? Any gotchas?

• How can I parse free text (Twitter tweets) against a large database of values?

  - by user136416

  Hi there Suppose I have a database containing 500,000 records, each representing, say, an animal. What would be the best approach for parsing 140 character tweets to identify matching records by animal name? For instance, in this string... "I went down to the woods to day and couldn't believe my eyes: I saw a bear having a picnic with a squirrel." ... I would like to flag up the words "bear" and "squirrel", as they appear in my database. This strikes me as a problem that has probably been solved many times, but from where I'm sitting it looks prohibitively intensive - iterating over every db record checking for a match in the string is surely a crazy way to do it. Can anyone with a comp sci degree put me out of my misery? I'm working in C# if that makes any difference. Cheers!

• SQL commands generated in Django by running sqlall

  - by k-g-f

  In my Django app, I just ran $ python manage.py sqlall and I see a lot of SQL statements that look like this, when describing FK relationships: ALTER TABLE `app1_model1` ADD CONSTRAINT model2_id_refs_id_728de91f FOREIGN KEY (`model2_id`) REFERENCES `app1_model2` (`id`); Where does "7218de91f" come from? I would like to know because I'd like to manually write SQL statements to accompany models changes in the app so that my db's can be kept up to date.

• Greatest not null column

  - by Álvaro G. Vicario

  I need to update a row with a formula based on the largest value of two DATETIME columns. I would normally do this: GREATEST(date_one, date_two) However, both columns are allowed to be NULL. I need the greatest date even when the other is NULL (of course, I expect NULL when both are NULL) and GREATEST() returns NULL when one of the columns is NULL. This seems to work: GREATEST(COALESCE(date_one, date_two), COALESCE(date_two, date_one)) But I wonder... am I missing a more straightforward method?

• Using * Width & Precision Specifiers With boost::format

  - by John Dibling

  I am trying to use width and precision specifiers with boost::format, like this: #include <boost\format.hpp> #include <string> int main() { int n = 5; std::string s = (boost::format("%*.*s") % (n*2) % (n*2) % "Hello").str(); return 0; } But this doesn't work because boost::format doesn't support the * specifier. Boost throws an exception when parsing the string. Is there a way to accomplish the same goal, preferably using a drop-in replacement?

• regex to match specific html tags

  - by Rco8786

  I need to match html tags(the whole tag), based on the tag name. For script tags I have this: <script.+src=.+(\.js|\.axd).+(</script>|>) It correctly matches both tags in the following html: <script src="Scripts/JScript1.js" type="text/javascript" /> <script type="text/javascript" src="Scripts/JScript2.js" /> However, when I do link tags with the following: <link.+href=.+(\.css).+(</link>|>) It matches all of this at once(eg it returns one match containing both items): <link href="Stylesheets/StyleSheet1.css" rel="Stylesheet" type="text/css" /> <link href="Stylesheets/StyleSheet2.css" rel="Stylesheet" type="text/css" /> What am I missing here? The regexes are essentially identical except for the text to match to? Also, I know that regex is not a great tool for HTML parsing...I will probably end up using the HtmlAgilityPack in the end, but this is driving me nuts and I want an answer if only for my own mental health!

• Creating interruptible process in python

  - by Glycerine

  I'm creating a python script of which parses a large (but simple) CSV. It'll take some time to process. I would like the ability to interrupt the parsing of the CSV so I can continue at a later stage. Currently I have this - of which lives in a larger class: (unfinished) Edit: I have some changed code. But the system will parse over 3 million rows. def parseData(self) reader = csv.reader(open(self.file)) for id, title, disc in reader: print "%-5s %-50s %s" % (id, title, disc) l = LegacyData() l.old_id = int(id) l.name = title l.disc_number = disc l.parsed = False l.save() This is the old code. def parseData(self): #first line start fields = self.data.next() for row in self.data: items = zip(fields, row) item = {} for (name, value) in items: item[name] = value.strip() self.save(item) Thanks guys.

• Will server-side JavaScript take off? Which implementation is most stable?

  - by Steve M

  Does anyone see server-side JavaScript taking off? There are a couple of implementations out there, but it all seems to be a bit of a stretch (as in, "doing it BECAUSE WE CAN" type of attitude). I'm curious to know if anyone actually writes JavaScript for the server-side and what their experiences with it have been to date. Also, which implementation is generally seen as the most stable?

• Using a database/index sequential file independently of the Unix distribution

  - by Helper Method

  What I'm planning to do is a) parse a file for some lines matching a regular expression b) store the match in some sort of database / file so I don't have to do the parsing again and again c) call another program passing the matches as arguments While I can imagine how to do a) and c), I'm a little bit unsure about b). The matches are of the form key:attribute1:attribute2:attribute3 where attribute 2 may be optional. I'm thinking of storing the results in a simple database but the problem is the database needs to available on a number of Unix platform for the program to work. Are there any (simple) databases which can be found on any Unix platforms? Or should I use some sort of index-sequential file?

• Question in Flex (parser)

  - by shkk

  Hello... I want to ask you a question about Flex, the program for parsing code. Supposing I have an instruction like this one, in the rules part: "=" BEGIN(attribution); <attribution>{var_name} { fprintf(yyout, "="); ECHO; } <attribution>";" BEGIN(INITIAL); {var_name} is a regular expression that matches a variable's name, and all I want to do is to copy at the output all the attribution instructions, such as a = 3; or b = a; My rule though cannot write with fprintf the left member of the attribution, but only = 3; or =a; One solution for that might be that, after I make the match "=" and I am in the attribution state, to go 2 positions back as to get the left operand as well. How can I do that in Flex?

• How to perform an action when a remote (Http) file changed?

  - by ZeissS

  Hi, I want to create a script that checks an URL and perform an action (download + unzip) when the "Last-Modified" header of the remote file changed. I thought about fetching the header with curl but then I have to store it somewhere for each file and perform a date comparison. Does anyone have a different idea using (mostly) standard unix tools? thanks
