• best place to store .net assemblies

  - by stackoverflow

  To give a scenario, let us simply assume an engine that loads plug-ins and exposes features in the plug-in. User 1 uploads a plug-in which allows implements Act 1 User 2 uploads a plug-in which allows implements Act 2 A plug-in in this case is .net assembly. Now in this scenario, if we have to store all the assemblies - what would be the best place? Also, the plug-in would require to be versioned so execution can happen of a particular version. Further considering the plug-in engine is installed on multiple machines or on same machine as different instances (similar to sql server). Would a centralized database (sql server 2005) with a table to store all the assembly be a good idea (centralized backup etc.,) (assembly size would be around 500kb to 1MB)

• Performance implications of using a variable versus a magic number

  - by Nathan

  I'm often confused by this. I've always been taught to name numbers I use often using variables or constants, but if it reduces the efficiency of the program, should I still do it? Heres an example: private int CenterText(Font font, PrintPageEventArgs e, string text) { int recieptCenter = 125; int stringLength = Convert.ToInt32(e.Graphics.MeasureString(text, font)); return recieptCenter - stringLength / 2; } The above code is using named variables, but runs slower then this code: private int CenterText(Font font, PrintPageEventArgs e, string text) { return 125 - Convert.ToInt32(e.Graphics.MeasureString(text, font) / 2); } In this example, the difference in execution time is minimal, but what about in larger blocks of code?

• Can a second stored procedure doing the same thing finish before first one?

  - by evanmortland

  Hello, I have an audit record table that I am writing to. I am connecting to MyDb, which has a stored procedure called 'CreateAudit', which is a passthrough stored procedure to another database on the same machine called 'CreatedAudit' as well. I call the CreateAudit stored procedure from my application, using subsonic as the DAL. The first time I call it, I call it with the following (pseudocode): Result = CreateAudit(recordId, "Opened") Right after that, I call: Result2 = CreateAudit(recordId, "Closed") In my second stored procedure it is supposed to mark the record that was created by the CreateAudit(recordId, "Opened") with a status of closed. It works great if I run them independently of one another, but when they run in sequence in the application, the record is not marked as "Closed". When I run SQL profiler I see that both queries ran, and if I copy the queries out and run them from query analyzer the record gets marked as closed 100% of the time! When I run it from the application, about once every 20 times or so, the record is successfully marked closed - the other 19 times nothing happens, but I do not get an error! Is it possible for the .NET app to skip over the ouput from the first stored procedure and start executing the second stored procedure before the record in the first is created? When I add a "WAITFOR DELAY '00:00:00:003'" to the top of my stored procedure, the record is also closed 100% of the time. My head is spinning, any ideas why this is happening! Thanks for any responses, very interested in hearing how this can happen.

• What is common between environments within a shell terminal session?

  - by Matt1776

  I have a custom shell script that runs each time a user logs in or identity is assumed, its been placed in /etc/profile.d and performs some basic env variable operations. Recently I added some code so that if screen is running it will reattach it without needing me to type anything. There are some problems however. If I log-in as root, and su - to another user, the code runs a second time. Is there a variable I can set when the code runs the first time that will prevent a second run of the code? I thought to write something to the disk but then I dont want to prevent the code from running if I begin a new terminal session. Here is the code in question. It first attempts to reattach - if unsuccessful because its already attached (as it might be on an interruped session) it will 'take' the session back. screen -r if [ -z "$STY" ]; then exec screen -dR fi Ultimately this bug prevents me from substituting user to another user because as soon as I do so, it grabs the screen session and puts me right back where I started. Pretty frustrating

• Ant Junit tests are running much slower via ant than via IDE - what to look at?

  - by Alex B

  I am running my junit tests via ant and they are running substantially slower than via the IDE. My ant call is: <junit fork="yes" forkmode="once" printsummary="off"> <classpath refid="test.classpath"/> <formatter type="brief" usefile="false"/> <batchtest todir="${test.results.dir}/xml"> <formatter type="xml"/> <fileset dir="src" includes="**/*Test.java" /> </batchtest> </junit> The same test that runs in near instantaneously in my IDE (0.067s) takes 4.632s when run through Ant. In the past, I've been able to speed up test problems like this by using the junit fork parameter but this doesn't seem to be helping in this case. What properties or parameters can I look at to speed up these tests? More info: I am using the reported time from the IDE vs. the time that the junit task outputs. This is not the sum total time reported at the end of the ant run. So, bizarrely, this problem has resolved itself. What could have caused this problem? The system runs on a local disk so that is not the problem.

• Using multiple Qt (SQL) Models

  - by radix07

  I have a near real-time application that I am using Qt and an SQLite database to run. I am curious if it is safe to have two separate models access a database at once. I know 2 separate views can access a model just fine, but I can't find any document addressing this. I also realize that SQLite is thread safe for reading, so I don't see a real issue to doing this from the SQLite part of things... Basically I want to use a QSqlTableModel to do the real-time read and write in the background and at the same time use a QSqlQueryModel to give the user desired data. Since I may be doing lots of filtering in the background using the table model I can't use it as the main view as well. I have gotten this to work for the most part, but am not sure if this is the best way to do this. If the models act like multiple SQL queries I don't believe this should be an issue, but I would like to know from someone I bit more knowledgeable about this stuff since this is pretty new to me. Thanks

• Basic formatting. sed, or cut, or what?

  - by dsclough

  Very new to this whole Unix thing. I'm currently using korn shell to try and format some lines of text. My input has a couple of lines that look something like this Date/Time :- Monday June 03 00:00:00 EDT 2013 Host Name :- HostNameHere PIDS :- NumbersNLetters Product Name :- ProductName The desired output would be as follows: Date/Time="Monday June 03 00:00:00 EDT 2013" HostName="HostNameHere" PIDS="NumbersNLetters" ProductName="ProductName" So, I need to get rid of any spaces in the leftmost column, and throw everything in the rightmost column between quotations. I've looked at the cut command, and got this far: Cut -f 1,2 -d - Which might produce a result like Date/Time:Monday June 03 00:00:00 EDT 2013, which is close to what I want, but not quite. I wasn't sure if cut could let me add parentheses, and it doesn't look like I can remove spaces that way either. sed seems like it might be closer to the answer, but I wasn't able to find through googling how I might just look for any pattern and not a specific one. I apologize for the incredibly basic question, but reading documentation only gets you so far before your brain starts to ache... If there are any better resources I should be looking at I would be happy to get pointed in the right direction. Thanks!

• Do I need something more to run NUnit under any directory?

  - by prosseek

  I have NUnit installed at this directory. C:\Program Files\NUnit 2.5.5\bin\net-2.0 When I try to run my unit test (mut.dll) in some random directory. I get the following error. I have to copy the mut.dll under the NUnit directory in order to run it. ProcessModel: Default DomainUsage: Single Execution Runtime: net-2.0 Could not load file or assembly 'nunit.framework, Version=2.5.5.10112, Culture=n eutral, PublicKeyToken=96d09a1eb7f44a77' or one of its dependencies. The system cannot find the file specified. What's wrong? Is there anything that I have to configure to run NUNit under any directory?

• Iterating over a database column in Django

  - by curious

  I would like to iterate a calculation over a column of values in a MySQL database. I wondered if Django had any built-in functionality for doing this. Previously, I have just used the following to store each column as a list of tuples with the name table_column: import MySQLdb import sys try: conn = MySQLdb.connect (host = "localhost", user = "user", passwd="passwd", db="db") except MySQLdb.Error, e: print "Error %d: %s" % (e.args[0], e.args[1]) sys.exit (1) cursor = conn.cursor() for table in ['foo', 'bar']: for column in ['foobar1', 'foobar2']: cursor.execute('select %s from %s' % (column, table)) exec "%s_%s = cursor.fetchall()" % (table, column) cursor.close() conn.commit() conn.close() Is there any functionality built into Django to more conveniently iterate through the values of a column in a database table? I'm dealing with millions of rows so speed of execution is important.

• MySQL Query - WHERE and IF?

  - by Prash

  I'm not quite sure how to right this query. Basically, I'm going to have a table with two columns (OS and country_code) - more columns too, but those are the conditional ones. These will be either set to 0 for all, or specific ones, separated by commas. Now, what I'm trying achieve is pull data from the table if the OS and country_code = 0, or if they contain matching data (separated by commas). Then, I have a column for time. I want to select rows where the time is GREATER than the time column, unless the column time_t is set to false, in which case this shouldn't matter. I hope I explained it right? This is what I kind of have so far: $get = $db->prepare("SELECT * FROM commands WHERE country_code = 0 OR country_code LIKE :country_code AND OS = 0 OR OS LIKE :OS AND IF (time_t = 1, expiry > NOW()) "); $get->execute(array( ':country_code' => "%{$data['country_code']}%", ':OS' => "%{$data['OS']}%" ));

• Why isn't this json/jquery function returning 10 results and why does it return 0 sometimes?

  - by Scarface

  Hey guys, quick question. I have a json function returning results from a php query but it is not working out because it seems to keep executing the query until all results are returned and sometimes returns 0 results (if I keep refreshing page, it returns 0 results sometimes). I want to limit results returned to 10 so I was wondering if anyone could point out the error of my code. Would really appreciate it. PS I am positive the query is returning the correct results and only 10 on its own. It just seems to be this one function that is not working out. SELECT time, user, comment FROM comments WHERE topic_id='$topic_id' ORDER BY time DESC LIMIT 10 var count=0; function prepare(response) { count++; var string = '<li class="list" id="list-'+count+'">' +'</li>'; return string; } $.getJSON(files+"comments.php?action=view&load=initial&topic_id="+topic_id+"&t=" + (new Date()), function(json) { if(json.length) { for(i=0; i < json.length; i++) { $('#shoutbox-list').prepend(prepare(json[i])); $('#list-' + count).fadeIn(1500); } var j = i-1; lastTime = json[j].time; } });

• Is Private Bytes >> Working Set?

  - by Jacob

  OK, this may sound weird, but here goes. There are 2 computers, A (Pentium D) and B (Quad Core) with almost the same amount of RAM running Windows XP. If I run the same code on both computers, the allocated private bytes in A never goes down resulting in a crash later on. In B it looks like the private bytes is constantly deallocated and everything looks fine. In both computers, the working set is deallocated and allocated similarly. Could this be an issue with manifests or DLLs (system)? I'm clueless. Note: I observed the utilized memory with Process Explorer. Question: During execution (where we have several allocations and deallocations) is it normal for the number of private bytes to be much bigger (1.5 GB vs 70 MB) than the working set?

• Drop into read-eval-print loop from PHP code?

  - by Mickey

  Is there a way to drop into a read-eval-print loop from inside PHP code during execution, in a script that was run from the command line? That is, like php -a or phpsh? Or do I have to re-implement a REPL from scratch? I can't find any way to do it. To clarify: the reason why I need to do this is that I want to automatically include all the files in my project once the REPL starts, instead of having to manually include everything by hand.

• Delete on a very deep tree

  - by Kathoz

  I am building a suffix trie (unfortunately, no time to properly implement a suffix tree) for a 10 character set. The strings I wish to parse are going to be rather long (up to 1M characters). The tree is constructed without any problems, however, I run into some when I try to free the memory after being done with it. In particularly, if I set up my constructor and destructor to be as such (where CNode.child is a pointer to an array of 10 pointers to other CNodes, and count is a simple unsigned int): CNode::CNode(){ count = 0; child = new CNode* [10]; memset(child, 0, sizeof(CNode*) * 10); } CNode::~CNode(){ for (int i=0; i<10; i++) delete child[i]; } I get a stack overflow when trying to delete the root node. I might be wrong, but I am fairly certain that this is due to too many destructor calls (each destructor calls up to 10 other destructors). I know this is suboptimal both space, and time-wise, however, this is supposed to be a quick-and-dirty solution to a the repeated substring problem. tl;dr: how would one go about freeing the memory occupied by a very deep tree? Thank you for your time.

• Where to turn upon realizing I can't program my way out of a paper bag?

  - by luminarious

  I have no job and just enough money to get by until April or so. While looking for work, I figured I might as well go through with a pet project, a browser based card game. Make it nice and free, collect donations and maybe earn enough for a movie ticket to escape reality for a while. I have dabbled in web development a bit. I can make simple stuff happen with JS/PHP if I follow tutorials. I designed my own art blog's template - http://luminarious.tumblr.com. I can visualise the game working in my head, flowcharts and everything. But then I tried to go deeper with Javascript and almost had an aneurysm before understanding what a closure is. Wether I suck at learning, have ADD or fail epically at productivity, I have not got much done. Coming up with ideas, screen mock-ups and so forth was very enjoyable, but actual implementation.. not so much. In fact, I cry a bit every time I think about the time someone competent could have finished this in. I'd like to excuse myself with my ENTP personality type, but that hardly solves anything. Rather, I'd like to know to get from A (bunch of ideas with little semblance to a web app) to B (something to proudly show others) while being unable to pay anyone? Are there any secret techniques for learning? Is there any way to get mentoring or code review? Is there anyone with too much free time willing to code for me? How to trust someone to not steal my code when I ask for assistance? Is there anything I should have asked instead of any of those?

• didSelectRowAtIndexPath being called after viewDidLoad of the called view

  - by Serguei Fedorov

  I am trying to pass variables over to the new view. I have the following code: appDelegate *dataCenter = (AppDelegate*)[[UIApplication sharedApplication] delegate]; dataCenter.myVariable = [array objectAtIndex:indexPath.row]; in the didSelectRowAtIndexPath of the calling view. However, the issue that I have is that this variable is empty in the vewDidLoad function of the next view, simply because it fired off BEFORE the didSelectRowAtIndexPath of the calling view. I am using storyboard to link the views together. Both are UITableView. If I hit back and then reselect the table element it is then set, granted that by the time I hit back and then selected again, the variable got set. Is there any way to for the order of execution? I really don't want to do UI view switching on the back end. Any help is greatly appreciated!

HttpRuntime.Cache.Insert("Members", AllMembersList, null, DateTime.Now.AddHours(1), TimeSpan.Zero); when i try and clear the cache object.. HttpRuntime.Cache.Remove("Members"); its value doesnt change, untill 1 hour is up or when i reset the server. My question.. for a cache object that is set absolute expiration, can i manually clear it or will it exist for the full hour ? what i would like is this object to last for an hour but depending on program execution be able to clear it so it will contain fresh data. any help is most appreciated truegilly

• Speed up this query joining to a table multiple times

  - by Mongus Pong

  Hi, I have this query that (stripped right down) goes something like this : SELECT [Person_PrimaryContact].[LegalName], [Person_Manager].[LegalName], [Person_Owner].[LegalName], [Person_ProspectOwner].[LegalName], [Person_ProspectBDM].[LegalName], [Person_ProspectFE].[LegalName], [Person_Signatory].[LegalName] FROM [Cache] LEFT JOIN [dbo].[Person] AS [Person_Owner] WITH (NOLOCK) ON [Person_Owner].[PersonID] = [Cache].[ClientOwnerID] LEFT JOIN [dbo].[Person] AS [Person_Manager] WITH (NOLOCK) ON [Person_Manager].[PersonID] = [Cache].[ClientManagerID] LEFT JOIN [dbo].[Person] AS [Person_Signatory] WITH (NOLOCK) ON [Person_Signatory].[PersonID] = [Cache].[ClientSignatoryID] LEFT JOIN [dbo].[Person] AS [Person_PrimaryContact] WITH (NOLOCK) ON [Person_PrimaryContact].[PersonID] = [Cache].[PrimaryContactID] LEFT JOIN [dbo].[Person] AS [Person_ProspectOwner] WITH (NOLOCK) ON [Person_ProspectOwner].[PersonID] = [Cache].[ProspectOwnerID] LEFT JOIN [dbo].[Person] AS [Person_ProspectBDM] WITH (NOLOCK) ON [Person_ProspectBDM].[PersonID] = [Cache].[ProspectBDMID] LEFT JOIN [dbo].[Person] AS [Person_ProspectFE] WITH (NOLOCK) ON [Person_ProspectFE].[PersonID] = [Cache].[ProspectFEID] Person is a huge table and each join to it has a pretty significant hit in the execution plan. Is there anyway I can adjust this query so that I am only linking to it once, or at least get SQL Server to scan through it only once?

• Can't declare an abstract method private....

  - by Zombies

  I want to do this, yet I can't. Here is my scenario and rational. I have an abstract class for test cases that has an abstract method called test(). The test() method is to be defined by the subclass; it is to be implemented with logic for a certain application, such as CRMAppTestCase extends CompanyTestCase. I don't want the test() method to be invoked directly, I want the super class to call the test() method while the sub class can call a method which calls this (and does other work too, such as setting a current date-time right before the test is executed for example). Example code: public abstract class CompanyTestCase { //I wish this would compile, but it cannot be declared private private abstract void test(); public TestCaseResult performTest() { //do some work which must be done and should be invoked whenever //this method is called (it would be improper to expect the caller // to perform initialization) TestCaseResult result = new TestCaseResult(); result.setBeginTime(new Date()); long time = System.currentTimeMillis(); test(); //invoke test logic result.setDuration(System.currentTimeMillis() - time); return result; } } Then to extend this.... public class CRMAppTestCase extends CompanyTestCase { public void test() { //test logic here } } Then to call it.... TestCaseResult result = new CRMAppTestCase().performTest();

• How to synchronize two (or n) replication processes for SQL Server databases?

  - by Yauheni Sivukha

  There are two master databases and two read-only copies updated by standard transactional replication. It is needed to map some entity from both read-only databases, lets say that A databases contains orders and B databases contains lines. The problem is that replication to one database can lag behind replication of second database, and at the moment of mapping R-databases will have inconsistent data. For example. We stored 2 orders with lines at 19:00 and 19:03. Mapping process started at 19:05, but to the moment of mapping A database replication processed all changes up to 19:03, but B database replication processed only changes up to 19:00. After mapping we will have order entity with order as of 19:03 and lines as of 19:00. The troubles are guaranteed:) In my particular case both databases have temporal model, so it is possible to fetch data for every time slice, but the problem is to identify time of latest replication. Question: How to synchronize replication processes for several databases to avoid situation described above? Or, in other words, how to compare last time of replication in each database? UPD: The only way I see to synchronize is to continuously write timestamps into service tables in each database and to check these timestamps on replicated servers. Is that acceptable solution?

• UITableView populating EVERY OTHER launch

  - by Joshmattvander

  I am having a problem that I cant seem to get to the bottom of. In my view did load code, I am creating an array and attempting to populate the table. For some reason it only populates the data on EVERY OTHER time the app is run. I put logs in viewDidLoad which runs as does viewWillAppear and outputs the correct count for the array. Also, the UITableView specicic methods get called when it works and they just don't get called when it doesnt work. I cant figure out the root of this problem. Again this occurrence happens exactly 50% of the time. Theres no dynamic data that could be tripping up or anything. #import "InfoViewController.h" @implementation InfoViewController - (void)viewDidLoad { NSLog(@"Info View Loaded"); // This runs infoList = [[NSMutableArray alloc] init]; //Set The Data //Theres 8 similar lines [infoList addObject :[[NSMutableDictionary alloc] initWithObjectsAndKeys: @"Scrubbed", @"name", @"scrubbed", @"url", nil]]; NSLog(@"%d", [infoList count]); // This shows the count correctly every time [super viewDidLoad]; } -(void) viewWillAppear:(BOOL)animated { NSLog(@"Info Will Appear"); // This Runs } - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { // This WILL NOT RUN when it doesnt work, and DOES show the count when it does run NSLog(@"Counted in numberOfRowsInSection %d", [infoList count]); return [infoList count]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { NSLog(@"ROW"); static NSString *CellIdentifier = @"infoCell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease]; } cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; cell.textLabel.text = [[infoList objectAtIndex:indexPath.row] objectForKey:@"name"]; return cell; } @end

• Staticly linked libraries not running code inside to setup static variables.

  - by MJD

  In a c++ project I am working on, I have a simple c++ file that needs to run some code at the beginning of the progam execution. This file is linked into a static library, which is then linked into the main program. I have similar code in other files running fine, that looks something like: bool ____nonexistant_value = executeAction(); However, it does not work inside this file unless I make use of a function implemented in this file. It does work if the library is compilied as a shared library. I'd prefer to link this statically as the library is only a convience as the file is in a different directory.

  Hello, I have a strange bug. I launch a PHP Unit test Suite. At the beginning, it executes a big query to initialize the database. If I put a breakpoint just after the execution of the sql, there is no problem and my tests pass. If I don't put any break point, they don't pass and say that the tables don't exist! It works as if the sql query was asynchronous! Do you have an idea of the bug? Or how to debug that? Thanks a lot in advance for your help, I'm lost! Farf

• Is it possible in SQLAlchemy to filter by a database function or stored procedure?

  - by Rico Suave

  We're using SQLalchemy in a project with a legacy database. The database has functions/stored procedures. In the past we used raw SQL and we could use these functions as filters in our queries. I would like to do the same for SQLAlchemy queries if possible. I have read about the @hybrid_property, but some of these functions need one or more parameters, for example; I have a User model that has a JOIN to a bunch of historical records. These historical records for this user, have a date and a debit and credit field, so we can look up the balance of a user at a specific point in time, by doing a SUM(credit) - SUM(debit) up until the given date. We have a database function for that called dbo.Balance(user_id, date_time). I can use this to check the balance of a user at a given point in time. I would like to use this as a criterium in a query, to select only users that have a negative balance at a specific date/time. selection = users.filter(coalesce(Users.status, 0) == 1, coalesce(Users.no_reminders, 0) == 0, dbo.pplBalance(Users.user_id, datetime.datetime.now()) < -0.01).all() This is of course a non-working example, just for you to get the gist of what I'd like to do. The solution looks to be to use hybrd properties, but as I mentioned above, these only work without parameters (as they are properties, not methods). Any suggestions on how to implement something like this (if it's even possible) are welcome. Thanks,
