• Searching with Linq

  - by Phil

  I have a collection of objects, each with an int Frame property. Given an int, I want to find the object in the collection that has the closest Frame. Here is what I'm doing so far: public static void Search(int frameNumber) { var differences = (from rec in _records select new { FrameDiff = Math.Abs(rec.Frame - frameNumber), Record = rec }).OrderBy(x => x.FrameDiff); var closestRecord = differences.FirstOrDefault().Record; //continue work... } This is great and everything, except there are 200,000 items in my collection and I call this method very frequently. Is there a relatively easy, more efficient way to do this?

• Problem getting IM information from an ABRecord

  - by bend0r

  Hello, I'm trying to get the IM account information from existing contacts (adressbook) on iPhone. I walk through the contacts and I get the contacts which have an entry in IM but I can't read the jabber-address. abArray = (NSArray *)ABAddressBookCopyArrayOfAllPeople(ABAddressBookCreate()); for(int i=0 ; i<[abArray count];i++) { ABRecordRef record = [abArray objectAtIndex:i]; ABMutableMultiValueRef multi = ABRecordCopyValue(record, kABPersonInstantMessageProperty); for(CFIndex x=0;x<ABMultiValueGetCount(multi);x++) { CFDictionaryRef dict = ABMultiValueCopyValueAtIndex(multi, x); CFStringRef jabber = CFDictionaryGetValue(dict, kABPersonInstantMessageServiceJabber); if(CFDictionaryContainsKey(dict, kABPersonInstantMessageServiceJabber)) { NSLog(@"yes"); } else { NSLog(@"no"); } // only to make it possible to log to console NSString *jaab = (NSString *)jabber; NSLog(@"jabber adress: %@" , jaab); } CFRelease(dict); } } what I'm doing wrong?

• Batch file to check if a file exists and raise an error if it doesn't

  - by cfdev9

  This batch file releases a build from TEST to LIVE. I want to add a check constraint in this file that ensures there is an accomanying release document in a specific folder. "C:\Program Files\Windows Resource Kits\Tools\robocopy.exe" "\\testserver\testapp$" "\\liveserver\liveapp$" *.* /E /XA:H /PURGE /XO /XD ".svn" /NDL /NC /NS /NP del "\\liveserver\liveapp$\web.config" ren "\\liveserver\liveapp$\web.live.config" web.config So I have a couple of questions about how to achieve this... There is a version.txt file in the \testserver\testapp$ folder and the only contents of this file is the build number (eg 45 - for build 45) How do I read the contents of the version.txt file into a variable in the batch file? How do I check if a file \fileserver\myapp\releasedocs\ {build}.doc exists using the variable from part 1 in place of {build}?

• Python - Things I shouldn't be doing?

  - by cornjuliox

  I've got a few questions about best practices in Python. Not too long ago I would do something like this with my code: ... junk_block = "".join(open("foo.txt","rb").read().split()) ... I don't do this anymore because I can see that it makes code harder to read, but would the code run slower if I split the statements up like so: f_obj = open("foo.txt", "rb") f_data = f_obj.read() f_data_list = f_data.split() junk_block = "".join(f_data_list) I also noticed that there's nothing keeping you from doing an 'import' within a function block, is there any reason why I should do that?

• Top techniques to avoid 'data scraping' from a website database

  - by Addsy

  I am setting up a site using PHP and MySQL that is essentially just a web front-end to an existing database. Understandably my client is very keen to prevent anyone from being able to make a copy of the data in the database yet at the same time wants everything publicly available and even a "view all" link to display every record in the db. Whilst I have put everything in place to prevent attacks such as SQL injection attacks, there is nothing to prevent anyone from viewing all the records as html and running some sort of script to parse this data back into another database. Even if I was to remove the "view all" link, someone could still, in theory, use an automated process to go through each record one by one and compile these into a new database, essentially pinching all the information. Does anyone have any good tactics for preventing or even just dettering this that they could share. Thanks

• Querying MySQL with CodeIgniter, selecting rows where field is NULL

  - by rebellion

  I'm using CodeIgniter's Active Record class to query the MySQL database. I need to select the rows in a table where a field is not set to NULL: $this->db->where('archived !=', 'NULL'); $q = $this->db->get('projects'); That only returns this query: SELECT * FROM projects WHERE archived != 'NULL'; The archived field is a DATE field. Is there a better way to solve this? I know I can just write the query myself, but I wan't to stick with the Active Record throughout my code.

• Linq-to-Sql not detecting change in xml

  - by porum

  I have an xml field (Answers) in Sql Server, but when changing the content via Linq-to-Sql, the record is not flagged for updating. e.g. in Linqpad... var profile = Profiles.FirstOrDefault(p => p.Answers != null); profile.Answers.SetAttributeValue("date", DateTime.Now.ToString()); GetChangeSet().Dump(); // nothing flagged profile.Answers = new XElement(profile.Answers); // ends up with correct xml GetChangeSet().Dump(); // record is flagged as changed Any suggestions apart from assigning a clone of itself to the field or storing the xml as a string to force the update?

• CONTAINSTABLE with wildcard works different in SQLServer 2005 and SQLServer 2008?

  - by musuk

  I have two same databases one on SQLServer 2005 and one on SqlServer 2008, it have same SQL_Latin1_General_CP1_CI_AS Collation, and full text search catalogs have the same settings. These two databases contains table with same data, NTEXT string: "...kræve en forklaring fra miljøminister Connie Hedegaard.." My problem is: CONTAINSTABLE on SQLServer 2008 finds nothing if query is: select * from ContainsTable(SearchIndex_7, Content, '"miljø*"') ct but SQLServer 2005 works perfectly and finds necessary record. SQLServer 2008 finds necessary record if query is: select * from ContainsTable(SearchIndex_7, Content, '"milj*"') ct or select * from ContainsTable(SearchIndex_7, Content, '"miljøminister"') What can be reason for so strange behavior?

• Create Duplicate Records on SELECT for Calendar Date Range

  - by peterallcdn

  Hey all, I've built a pretty shnazzy calendar system but there is one tweak that I need to make so that I'm completely happy with it. My calendar has three tables: calevents - The calendared event. caldates - The occurrences and date-range of each occurrence for each event. calcats - The categories that can be applied to an event. The short: For each calevent, there can be many caldates, one for each occurrence of calevent. So a calevent that repeats weekly and spans 3 days might have caldates like this: date_id date_eid date_start date_end 2 37 2010-06-21 2010-06-23 3 37 2010-06-28 2010-06-30 7 37 2010-07-05 2010-07-07 9 37 2010-07-12 2010-07-14 What I want to do, is when selecting all the caldates for a specified month such as 2010-06, to return not just the two records above, but instead a record for each date in the range of date_start and date_end for each caldate. So if I searched for 2010-06, I would get: date_id date_eid date_start date_end date_day 2 37 2010-06-21 2010-06-23 2010-06-21 2 37 2010-06-21 2010-06-23 2010-06-22 2 37 2010-06-21 2010-06-23 2010-06-23 3 37 2010-06-28 2010-06-30 2010-06-28 3 37 2010-06-28 2010-06-30 2010-06-29 3 37 2010-06-28 2010-06-30 2010-06-30 The Long: The reason I want to do this, is so when displaying a list of events(calevents) for a specified month, an occurrence(caldates) of that event will be displayed for EACH of the days it spans. I could do this with php by looping through each day of the current month and displaying a copy of each caldate if the month day falls between date_start and date_end. But doing it this way will prevent me from using record pagination if needed. For example, if for a specified month the following caldates were returned: date_id date_eid date_start date_end 2 37 2010-06-21 2010-06-27 94 53 2010-06-09 2010-07-08 Doing record pagination would see this as only 2 records("rows"). But looping through them with PHP would generate 29 "rows". So, I figure if I use mysql to create each row instead of PHP, I can achieve the same thing AND still be able to use pagination if a month has a lot of events/dates. As far as performance goes, I'm not sure which option is more efficient. Both would send the same amount of info to the browser, so it's really only the work required to generate the info that matters. My current query which fetches all the occurrences for a specified month, and to make things just a little more complicated... joins them with their event and category, looks like this: $sql_to_execute = " SELECT date_id, date_eid, date_start, date_end, event_id, event_title, event_category, event_private, event_location, SUBSTRING_INDEX(event_detailsstripped, ' ', 40) AS event_detailsstripped, event_time, event_starttime, event_endtime, event_active, cat_colour FROM ( caldates LEFT JOIN calevents ON caldates.date_eid = calevents.event_id ) LEFT JOIN calcats ON calevents.event_category = calcats.cat_id WHERE date_start <= '".mysql_real_escape_string($dbi_list_end_date)."' AND date_end >= '".mysql_real_escape_string($dbi_list_start_date)."' ".$dbi_category." ORDER BY date_start ASC "; Any help or advice would be greatly appreciated! Thanks, Peter

• how can I make pip/setuptools understand that my package is in ./src?

  - by Giacomo Lacava

  I have a library with a layout like this in Github: README setup.py src/ somelibrary.py Note: I cannot change the layout, but I can change setup.py. I want to be able to reference this library from requirements.txt, so that people can do pip install -r requirements.txt and have it installed automagically. So I add a line like this into requirements: -e git+http://blablabla/blabla#egg=somelibrary This will clone the repository under ./src/somelibrary and then run setup.py develop on it, which will just add a link to ./src/somelibrary under site-packages. Unfortunately, because the library is actually under ./src/somelibrary/src, it seems like python can't see the library correctly. What am I missing? I guess it must be a setup.py option I'm not using correctly.

• Avoiding nesting two for loops

  - by chavanak

  Hi, Please have a look at the code below: import string from collections import defaultdict first_complex=open( "residue_a_chain_a_b_backup.txt", "r" ) first_complex_lines=first_complex.readlines() first_complex_lines=map( string.strip, first_complex_lines ) first_complex.close() second_complex=open( "residue_a_chain_a_c_backup.txt", "r" ) second_complex_lines=second_complex.readlines() second_complex_lines=map( string.strip, second_complex_lines ) second_complex.close() list_1=[] list_2=[] for x in first_complex_lines: if x[0]!="d": list_1.append( x ) for y in second_complex_lines: if y[0]!="d": list_2.append( y ) j=0 list_3=[] list_4=[] for a in list_1: pass for b in list_2: pass if a==b: list_3.append( a ) kvmap=defaultdict( int ) for k in list_3: kvmap[k]+=1 print kvmap Normally I use izip or izip_longest to club two for loops, but this time the length of the files are different. I don't want a None entry. If I use the above method, the run time becomes incremental and useless. How am I supposed to get the two for loops going? Cheers, Chavanak

• $_GET loading content before head tag instead of in specified div.

  - by s32ialx

  NOT EDITING BELOW BUT THANKS TO SOME REALLY NICE PEOPLE I CAN'T POST AN IMAGE ANYMORE BECAUSE I HAD a 15 Rep but NOW ONLY A 5 becuase my question wasn't what they wanted help with they gave me a neg rep. The problem is that the content loads it displays UNDER the div i placed #CONTENT# inside so the styles are being ignored and it's posting #CONTENT# outside the divs at positions 0,0 any suggestions? Found out whats happening by using "View Source" seems that it's putting all of the #CONTENT#, content that's being loaded in front of the <head> tag. Like this <doctype...> <div class="home"> \ blah blah #CONTENT# bot being loaded in correct specified area </div> / <head> <script src=""></script> </head> <body> <div class="header"></div> <div class="contents"> #CONTENT# < where content SHOULD load </div> <div class="footer"></div> </body> so anyone got a fix? OK so a better description I'll add relevant screen-shots Whats happening is /* file.class.php */ <?php $file = new file(); class file{ var $path = "templates/clean"; var $ext = "tpl"; function loadfile($filename){ return file_get_contents($this->path .

• Prevent Django from redirecting to add trailing slash

  - by konrad

  UPDATED: Sorry, it looks like it's Apache that's rewriting it for some reason, not Django. I'll investigate further and post my findings. I need to add a /xmlrpc.php to my Byteflow installation to handle an application that is written for PHP blog engines and uses this hardcoded path. For some reason Byteflow appends a slash to this URL using a 301 Moved Permanently redirect, which breaks the application. It does not do so for the /robots.txt that is configured in a similar way. Relevant lines from the project urls.py: url(r'^xmlrpc.php$', 'django_xmlrpc.views.xmlrpc_handler'), url(r'^robots.txt$', include('robots.urls')), I read that the behavior was changed in the Django codebase in commit 6852 (in 2007) to prevent redirects being done for urls that have been explicitly configured not to contain any trailing slashes. I'm using Django 1.1. I assume that once I have fixed this problem, I should be able to use this application with Byteflow, because the application uses the MetaWeblog XML-RPC API. Any clue?

• Suspended Laptop Cannot Wake Up - Ubuntu

  - by Zack

  I've got an ASUS G73JH, and whenever I suspend it or hibernate it, it will not wake up. The screen stays backlight but is black. The fan remains running, however the HDD does not, not disk activity is noticeable (audibly (It's not a SSD)). I can't: Awaken it with the keyboard Awaken it with the mouse Soft power-off by pressing the power button Change virtual screens by pressing Ctrl-Alt-# Restart X by pressing Ctrl-Alt-Backspace I have to hold down the power button and shut it down that way, and this seems a little unreasonable. Is there a place I could look for more detail as to what's causing this? Is there a known quick-fix to this issue? Nothing is logged as happening when the system is in "suspend" mode. Here's what happened immediately before and after the suspend "happened," note the time gap: May 4 17:46:13 tofu NetworkManager: <info> (eth0): carrier now OFF (device state 1) May 4 17:48:57 tofu kernel: imklog 4.2.0, log source = /proc/kmsg started.

• checking if records exists in DB, in single step or 2 steps?

  - by Sinan

  Suppose you want to get a record from database which returns a large data and requires multiple joins. So my question would be is it better to use a single query to check if data exists and get the result if it exists. Or do a more simple query to check if data exists then id record exists, query once again to get the result knowing that it exists. Example: 3 tables a, b and ab(junction table) select * from from a, b, ab where condition and condition and condition and condition etc... or select id from a, b ab where condition then if exists do the query above. So I don't know if there is any reason to do the second. Any ideas how this affects DB performance or does it matter at all?

• High Throughput and Windows Workflow Foundation

  - by SometimesUseful

  Can WWF handle high throughput scenarios where several dozen records are 'actively' being processed in parallel at any one time? We want to build a workflow process which handles a few thousand records per hour. Each record takes up to a minute to process, because it makes external web service calls. We are testing Windows Workflow Foundation to do this. But our demo programs show processing of each record appear to be running in sequence not in parallel, when we use parallel activities to process several records at once within one workflow instance. Should we use multiple workflow instances or parallel activities? Are there any known patterns for high performance WWF processing?

• Writing from an array to a file bash and new lines

  - by S1syphus

  I'm trying to write a script the generates a template file for Pashua (a perl script for creating GUI on osx) I want to crate an instance for each item in the array, so the ideal output would be: AB1.type = openbrowser AB1.label = Choose a master playlist file AB1.width=310 AB1.tooltip = Blabla filesystem browser AB2.type = openbrowser AB2.label = Choose a master playlist file AB2.width=310 AB2.tooltip = Blabla filesystem browser ...and so on for the rest of the array: What I am using to write to the text file at the moment is: count=1 saveIFS="$IFS" IFS=$'\n' array=($(<TEST.txt)) IFS="$saveIFS" for i in "${array[@]}"; do declare AD$count="$i"; ((count++)); done for i in "${array[@]}"; do echo "AD$count".type = openbrowser "AD$count".label = Choose a master playlist file \n "AD$count".width=310 \n "AD$count".tooltip = Blabla filesystem browser \n" >> long.txt; done However \n doesn't produce a newline in the text file, and I am pretty sure there is a alot nicer way todo this, ideas?

• Get the AVG of two SQL Access Queries

  - by reggiereg

  Hi, I'm trying to get the AVERAGE from the results of two separate sql queries built in MS Access. The first sql query pulls the largest record: SELECT DISTINCTROW Sheet1.Tx_Date, Sheet1.LName, Sheet1.Patient_Name, Sheet1.MRN, Max(Sheet1.) AS [Max Of FEV1_ACT], Max(Sheet1.FEF_25_75_ACT) AS [Max Of FEF_25_75_ACT] FROM Sheet1 GROUP BY Sheet1.Tx_Date, Sheet1.LName, Sheet1.Patient_Name, Sheet1.MRN; The second sql query pulls the second largest record: SELECT Sheet1.MRN, Sheet1.Patient_Name, Sheet1.Lname, Max(Sheet1.FEV1_ACT) AS 2ndLrgOfFEV1_ACT, Max(Sheet1.FEF_25_75_ACT) AS 2ndLrgOfFEF_25_75_ACT FROM Sheet1 WHERE (((Sheet1.FEV1_ACT)<(SELECT MAX( FEV1_ACT ) FROM Sheet1 ))) GROUP BY Sheet1.MRN, Sheet1.Patient_Name, Sheet1.Lname; These two queries work great, I just need some help on pulling the AVERAGE of the results of these two queries into one. Thanks.

• Rails - How do i update a records value in a join model ?

  - by ChrisWesAllen

  I have a join model in a HABTM relationship with a through association (details below). I 'm trying to find a record....find the value of that records attribute...change the value and update the record but am having a hard time doing it. The model setup is this User.rb has_many :choices has_many :interests, :through => :choices Interest.rb has_many :choices has_many :users, :through => :choices Choice.rb belongs_to :user belongs_to :interest and Choice has the user_id, interest_id, score as fields. And I find the ?object? like so @choice = Choice.where(:user_id => @user.id, :interest_id => interest.id) So the model Choice has an attribute called :score. How do I find the value of the score column....and +1/-1 it and then resave? I tried @choice.score = @choice.score + 1 @choice.update_attributes(params[:choice]) flash[:notice] = "Successfully updated choices value." but I get "undefined method score"......What did i miss?

• What is the best way to implement an object cache with Entity Framework?

  - by Harshal

  Say I have a table of "BlogPosts" in a database and i want to be able to cache the ones that were retrieved already in memory, for further reads, I can just use a standard hashtable type memory cache like System.Web.Caching.Cache, but if i then need to update a property on one of these blog posts e.g. blogPost.Title and update the record in DB, i cannot do this without fetching it again from database as the Entity Framework context used to fetch this record when it was loaded into my cache is already disposed? How do I write code so that I am getting an object from my cache, updating one property and just calling the SaveChanges method without incurring an extra read.

• Error with default argument in Source.getLines (Scala 2.8.0 RC1)

  - by Derek

  assuming I running Scala 2.8.0 RC1, the following scala code should print out the content of the file "c:/hello.txt" for ( line<-Source.fromPath( "c:/hello.txt" ).getLines ) println( line ) However, when I run it, I get the following error <console>:10: error: missing arguments for method getLines in class Source; follow this method with `_' if you want to treat it as a partially applied function Error occured in an application involving default arguments. val it = Source.fromPath("c:/hello.scala").getLines From what I understand, Scala should use the default argument "compat.Platform.EOL" for "getLines". I am wondering if I did wrong or is it a bug in scala 2.8 Thanks
