• Windows FTP batch sript to read & dl from external user list

  - by Will Sims

  i have several old, unused batches that i'm redoing.. I have a batch file for an old network arch from several years ago.. the main thing I'd like it to do now is read a list of files.. I'll explain the setup.. Server updates a complete list [CurrentMediaStores.txt] 2x a day. The laptops can set settings to DL this list through their start.bat which also runs addins and updates I aply to my pc's, to give my batches and myself a break from slavish folder assignments and add a lil more dynamics and less adminin the bats now call on a list the user makes by simply copying a line from the CMS.txt file and pasting it into their [Grab_List.txt] My problem is though I have the branch :: off right now and the code that detects if LAN is connected or not to switch to an ftp connection. I'd like for the ftp batch to call/ use the Grab_List also. but I just can't/ don't know how to pass and do the for loop with a ftp session to loop through x amount of files in the users req list.. Anyhelp would be greatly appreciated

• Rolling back file moves, folder deletes and mysql queries

  - by Workoholic

  This has been bugging me all day and there is no end in sight. When the user of my php application adds a new update and something goes wrong, I need to be able to undo a complex batch of mixed commands. They can be mysql update and insert queries, file deletes and folder renaming and creations. I can track the status of all insert commands and undo them if an error is thrown. But how do I do this with the update statements? Is there a smart way (some design pattern?) to keep track of such changes both in the file structure and the database? My database tables are MyISAM. It would be easy to just convert everything to InnoDB, so that I can use transactions. That way I would only have to deal with the file and folder operations. Unfortunately, I cannot assume that all clients have InnoDB support. It would also require me to convert many tables in my database to InnoDB, which I am hesitant to do.

• What algorithm should i follow to retrieve data in the prescribed format?

  - by Prateek

  I have to retrieve data from a database in which tables are consisting of fields like "ttc, rm, atc and lta" namely. Actually these values are stored on daily basis with a 15 min interval like From_time to_time ttc rm atc lta 00:00 00:15 45 10 35 25, 00:15 00:30 35 10 25 25 and so on .. These values are stored for every day of every month and i want it to be previewed in the prescribed format then what algorithm should i follow. I am confused about how to do comparisons for a format like below mentioned. The format is at this link https://drive.google.com/a/itbhu.ac.in/file/d/0B_J0Ljq64i4Za2J1V0lvbDZ4eGc/edit?usp=sharing To be specific once again, my question is, I have to prepare a report from the retrieved data which is being stored in the databases as explained above. But the report which is going to be prepared will be of entire month. So, to say the least, there may be cases that for two particular days the value of "ttc" would be same for some time so i want it to be listed together (as shown in format). And the confusing part is any of the values "ttc", "rm", "atc", "lta" can be same for any particular interval. So what algorithm should i follow for such comparisons. And if still any query with question, u can ask your doubt. Thanks

• Building Paypal based membership website - total noob - would appreciate help

  - by Ali

  this is a follow up on my question on paypal integration. I'm working ona membership site for racing fans. My membership site has 3 membership levels - free, gold and premium. When a user signs up he/she can gets a free membership on the spot but has the option to upgrade to a gold membership for 4 Dollars a month or a premium membership for 10 Dollars a month. I've gone through the paypal integration guide a few times though and have a vague understanding of how to get this to work. I think the recurring payments option would be fine enough - however I don't know how do I implement this in my system. Like when a user decides to go for a paid account i.e. Gold or premium from basic - what should I do on both my code side and on the paypal account side - I'd really appreciate if anyone would outline what I'd have to do here. Plus when a user decides to upgrade from lets say a Gold to a premium account - there is the issue of computing how much should be charged to upgrade his/her account eg: a user has been billed for 4 dollars and the next day opts to go for a premium account so assuming that the surplus for the rest of the month is 5 dollars and further from that all payments would be recurring 10 dollars monthly - how do I implement this? And in case a user decides to downgrade from a premium account of 10 dollars a month to a gold account of 4 dollars a month - how do I handle the surplus which would have to be refunded for that month alone and changing the membership? And like wise if someone wishes to cancel membership and go to having a free account - how do I refund whatever is owed and cancel the subscription. I'm sorry if it sounds like I'm asking to be spoon fed :( I'm quite new to this and this is for a client and I would really appreciate all the help here and really have to get this working right. Thanks again everyone - waiting for all your replies.

• activemessaging with stomp and activemq.prefetchSize=1

  - by Clint Miller

  I have a situation where I have a single activemq broker with 2 queues, Q1 and Q2. I have two ruby-based consumers using activemessaging. Let's call them C1 and C2. Both consumers subscribe to each queue. I'm setting activemq.prefetchSize=1 when subscribing to each queue. I'm also setting ack=client. Consider the following sequence of events: 1) A message that triggers a long-running job is published to queue Q1. Call this M1. 2) M1 is dispatched to consumer C1, kicking off a long operation. 3) Two messages that trigger short jobs are published to queue Q2. Call these M2 and M3. 4) M2 is dispatched to C2 which quickly runs the short job. 5) M3 is dispatched to C1, even though C1 is still running M1. It's able to dispatch to C1 because prefetchSize=1 is set on the queue subscription, not on the connection. So the fact that a Q1 message has already been dispatched doesn't stop one Q2 message from being dispatched. Since activemessaging consumers are single-threaded, the net result is that M3 sits and waits on C1 for a long time until C1 finishes processing M1. So, M3 is not processed for a long time, despite the fact that consumer C2 is sitting idle (since it quickly finishes with message M2). Essentially, whenever a long Q1 job is run and then a whole bunch of short Q2 jobs are created, exactly one of the short Q2 jobs gets stuck on a consumer waiting for the long Q1 job to finish. Is there a way to set prefetchSize at the connection level rather than at the subscription level? I really don't want any messages dispatched to C1 while it is processing M1. The other alternative is that I could create a consumer dedicated to processing Q1 and then have other consumers dedicated to processing Q2. But, I'd rather not do that since Q1 messages are infrequent--Q1's dedicated consumers would sit idle most of the day tying up memory.

• Find out which row caused the error

  - by Felipe Fiali

  I have a big fat query that's written dynamically to integrate some data. Basically what it does is query some tables, join some other ones, treat some data, and then insert it into a final table. The problem is that there's too much data, and we can't really trust the sources, because there could be some errored or inconsistent data. For example, I've spent almost an hour looking for an error while developing using a customer's database because somewhere in the middle of my big fat query there was an error converting some varchar to datetime. It turned out to be that they had some sales dating '2009-02-29', an out-of-range date. And yes, I know. Why was that stored as varchar? Well, the source database has 3 columns for dates, 'Month', 'Day' and 'Year'. I have no idea why it's like that, but still, it is. But how the hell would I treat that, if the source is not trustable? I can't HANDLE exceptions, I really need that it comes up to another level with the original message, but I wanted to provide some more info, so that the user could at least try to solve it before calling us. So I thought about displaying to the user the row number, or some ID that would at least give him some idea of what record he'd have to correct. That's also a hard job because there will be times when the integration will run up to 80000 records. And in an 80000 records integration, a single dummy error message: 'The conversion of a varchar data type to a datetime data type resulted in an out-of-range datetime value' means nothing at all. So any idea would be appreciated. Oh I'm using SQL Server 2005 with Service Pack 3.

• Querying datetime.datetime on appengine acts different then dev server help!

  - by Alon Carmel

  Hey, I'm having some trouble with stuff that work locally and dont work on the app engine python environment: Basically, i want to get a program from an epg between ranges of date and time. i know i cannot do two where < so i saw a suggestion to save the dates as list as datetime.datetime which i did. [datetime.datetime(2010, 5, 10, 14, 25), datetime.datetime(2010, 5, 10, 15, 0)] This is ok. but when i try to compare to it: progranon = get_object(Programs2Channel, 'channel_id =', channelobj.key(), 'endstartdate >', programstart_minex, 'endstartdate <', programstart_minex ) This for some reason works locally, but fails to retrieve the data on the app engine. *Im using Google app engine django patch which uses the get_object to retrieve data in transactions. Please help. Here are more details: this is the LIST: [datetime.datetime(2010, 5, 13, 10, 45), datetime.datetime(2010, 5, 13, 11, 30)] #this is the query: programstart = ""+year+"-"+month+"-"+day+" "+hour+":"+minute programstart_minex = datetime.strptime(programstart, "%Y-%m-%d %H:%M") progranon = Programs2Channel.gql('WHERE channel_id = :channelid AND endstartdate > :programstartx AND endstartdate < :programstartx',channelid = channelobj.key(),programstartx=programstart_minex).get()

• Adding Mysql Columns in Rails Rake

  - by Gigg

  I have a rake file that does a series of calculations on a database. Basically it adds usage on equipment regularly. At the end of the day it needs to add that days total to a monthly total table and update that same table. i use the following simple concepts: To get data from the database is pretty simple: @usages = Usage.find(:all) time = Time.new for usage in @usages sql = ActiveRecord::Base.connection To insert it into the database: sql.execute "INSERT (or UPDATE) into usages ## add values and options as per MySQL But how do I: take a column from a database, add all of its values together that have a common value in another column, (i.e. if column x == value y) and then insert it into another column in another table, say dailyusages? I have tried these options: task (:monthly => :environment) do @dailyusages = Dailyusage.find(:all) for dailyusage in @dailyusages sql = ActiveRecord::Base.connection time = Time.new device = monthlyusages.device month = time.month if device == dailyusages.device ##&& month == dailyusages.month total = (dailyusage.total.sum.to_i) @monthlyusages = Monthlyusage.find(:all) for monthlyusage in @monthlyusages sql = ActiveRecord::Base.connection old_total = monthlyusage.total.to_i new_total = (old_total + total) sql.execute "UPDATE monthlyusages ( year, month, total, device ) values('#{time.year}', '#{time.month}', '#{total}', '#{dailyusage.device}' )" end I obviously have uncommented options and tried all sorts of things. Any help would really save me a load of trouble. Thanks in advance. (** BTW - I am new to rails, so go easy on me **)

• SQL Server performance issue.

  - by Jit

  Hi Friends, I have been trying to analyze performance issue with SQL Server 2005. We have 30 jobs, one for each databases (30 databases, one per each client). The jobs run at early morning at an interval of 5 minutes. When I run the job individually for testing, for most of the databases it finishes in 7 to 9 minutes. But when these jobs run at early morning, I see few jobs taking 2 to 3 hours to finish and the same takes few minutes as mentioned above if ran independently. We dont have any other job scheduled during that time, other than these 30 jobs. If we restart the server then for 2 or so days all the jobs finishes in few minutes, but over the period of time (from 3rd day suddenly), few jobs start taking hours to finish. What could be the possible reason of performance degradation over the period of time? I verified all the SPs and we uses temp tables and I made sure none of the temp table is left without dropping at the end of SP. Let me know what are the possible reasons for such behavior. Appreciate your time and help. Thanks

• Representing complex scheduled reoccurance in a database

  - by David Pfeffer

  I have the interesting problem of representing complex schedule data in a database. As a guideline, I need to be able to represent the entirety of what the iCalendar -- ics -- format can represent, but in a database. I'm not actually implementing anything relating to ics, but it gives a good scope of the type of rules I need to be able to model. I need to allow allow representation of a single event or a reoccurring event based on multiple times per day, days of the week, week of a month, month, year, or some combination of those. For example, the third Thursday in November annually, or the 25th of December annually, or every two weeks starting November 2 and continuing until September 8 the following year. I don't care about insertion efficiency but query efficiency is critical. The operation I will be doing most often is providing either a single date/time or a date/time range, and trying to determine if the defined schedule matches any part of the date/time range. Other operations can be slower. For example, given January 15, 2010 at 10:00 AM through January 15, 2010 at 11:00 AM, find all schedules that match at least part of that time. (i.e. a schedule that covers 10:30 - 11:00 still matches.) Any suggestions? I looked at http://stackoverflow.com/questions/1016170/how-would-one-represent-scheduled-events-in-an-rdbms but it doesn't cover the scope of the type of reoccurance rules I'd like to model.

• Is there a limit for the number of files in a directory on an SD card?

  - by jamesh

  I have a project written for Android devices. It generates a large number of files, each day. These are all text files and images. The app uses a database to reference these files. The app is supposed to clear up these files after a little use (perhaps after a few days), but this process may or may not be working. This is not the subject of this question. Due to a historic accident, the organization of the files are somewhat naive: everything is in the same directory; a .hidden directory which contains a zero byte .nomedia file to prevent the MediaScanner indexing it. Today, I am seeing an error reported: java.io.IOException: Cannot create: /sdcard/.hidden/file-4200.html at java.io.File.createNewFile(File.java:1263) Regarding the sdcard, I see it has plenty of storage left, but counting $ cd /Volumes/NO_NAME/.hidden $ ls | wc -w 9058 Deleting a number of files seems to have allowed the file creation for today to proceed. Regrettably, I did not try touching a new file to try and reproduce the error on a commandline; I also deleted several hundred files rather than a handful. However, my question is: are there hard limits on filesize or number of files in a directory? am I even on the right track here? Nota Bene: The SD card is as-is - i.e. I haven't formatted it, so I would guess it would be a FAT-* format. The FAT-32 format has hard limits of filesize of 2GB (well above the filesizes I am dealing with) and a limit of number of files in the root directory. I am definitely not writing files in the root directory.

• Reoccurring error "The current identity (NT AUTHORITY\NETWORK SERVICE) does not have write access to

  - by tuseau

  Hi, I keep receiving this error in my ASP.NET web app (below). I give the Network Service account rights to the specified folder, it runs fine for a while, but then within a day or two the error reoccurs, as the Network Service account has been removed from the rights for the folder. Adding it again fixes it, but why does it keep reocurring? Could it be anything to do with using Interop components (such as WMI)? Here's the full error: Server Error in '/DriveMonitor' Application.

• jquery google visual api graph's data rows does not work.

  Hi! I'd like to use google drawVisualization API. Example: var data = new google.visualization.DataTable(); data.addColumn('string'); data.addColumn('number'); data.addRows([ ['a', 14], ['b', 47], ['c', 80], ['d', 55], ['e', 16], ['f', 90], ['g', 29], ['h', 23], ['i', 58], ['j', 48] ]); My version gets elements by an other google api, and join them, and after place the variable between ([ and ]), to be like in the example. var outputGraph = []; for (var i = 0, entry; entry = entries[i]; ++i) { var asd = [ entry.getValueOf('ga:pageTitle'), entry.getValueOf('ga:pageviews') ].join("',"); outputGraph.push(" ['" + asd + "]"); //get the 2 elements and join them to be like ['asd', 2], } // this is fine, the outputgraph is like ['asd', 2], ['asd', 2], ['asd', 2] as seen in the example var outputGraphFine = ("(["+outputGraph+"])"); // i suggest this is which fails the script. var data = new google.visualization.DataTable(); data.addColumn('string', 'Task'); data.addColumn('number', 'Hours per Day'); data.addRows = outputGraphFine; But it doesn't work.

• How to determine the size of a project (lines of code, function points, other)

  - by sixtyfootersdude

  How would you evaluate project size? Part A: Before you start a project. Part B: For a complete project. I am interested in comparing unrelated projects. Here are some options: 1) Lines of code. I know that this is not a good metric of productivity but is this a reasonable measure of project size? If I wanted to estimate how long it would take to recreate a project would this be a reasonable way to do it? How many lines of code should I estimate a day? 2) Function Points. Functions points are defined as the number of: inputs outputs inquires internal files external interfaces Anyone have a veiw point on whether this is a good measure? Is there a way to **actually do this? Does anyone have another solution? Hours taken seems like it could be a useful metric but not solely. If I ask you what is a "bigger program" and give you two programs how would you approach the question? I have seen several discussions of this on stackover flow but most discuss how to measure programmer productivity. I am more interested in project size.

• How to choose light version of database system

  - by adopilot

  I am starting one POS (Point of sale) project. Targeting system is going to be written in C# .NET 2 WinForms and as main database server We are going to use MS-SQL Server. As we have a lot of POS devices in chain for one store I will love to have backend local data base system on each POS device. Scenario are following: When main server goes down!! POS application should continue working "off-line" with local database, until connection to main server come up again. Now I am in dilemma which local database is going to be most adoptable for me. Here is some notes for helping me point me in right direction: To be Light "My POS devices art usually old and suffering with performances" To be Free "I have a lot of devices and I do not wont additional cost beside main SQL serer" One day Ill love to try all that port on Mono and Linux OS. Here is what I've researched so far: Simple XML "Light but I am afraid of performance, My main table of items is average of 10K records" SQL-Express "I am afraid that my POS devices is poor with hardware for SQLExpress, and also hard to install on each device and configure" Less known Advantage Database Server have free distribution of offline ADT system. DBF with extended Library,"Respect for good old DBFs but that era is behind Me with clipper and DBFs" MS Access Sqlite "Mostly like for now, but I am afraid how it is going to pair with MS SQL do they have same Data types". I know that in this SO is a lot of subjective data, but at least can someone recommended some others lite database system, or things that I shod most take attention before I choice database.

• FQL query using stream table doesn't accept app access token

  I've searched stackoverflow all day long to find an answer without luck, so here we go.

• topic-comment naming of functions/methods

  - by Daniel

  I was looking at American Sign Language the other day... and I noticed that the construction of the language was topic-comment. As in "Weather is good". That got me to thinking about why we name methods/functions in the manner of: function getName() { ... } function setName(v) { ... } If we think about naming in a topic-comment function, the function names would be function nameGet() { ... } function nameSet() { ... } This might be better for a class had multiple purposes. IE: class events { function ListAdd(); function ListDelete(); function ListGet(); function EventAdd(); function EventDelete(); function EventGet(); } This way the functions are grouped by "topic". Where as the former naming, functions are grouped Action-Noun, but are sorted by Noun. I thought this was an interesting POV, what do other people think about naming functions/methods Topic-Comment? Obviously, mixing naming conventions up in the same project would be weird, but overall? -daniel

• Idea for a small project, should I use Python?

  - by Robb

  I have a project idea, but unsure if using Python would be a good idea. Firstly, I'm a C++ and C# developer with some SQL experience. My day job is C++. I have a project idea i'd like to create and was considering developing it in a language I don't know. Python seems to be popular and has piqued my interests. I definitely use OOP in programming and I understand Python would work fine with that style. I could be way off on this, I've only read small bits and pieces about the language. The project won't be public or anything, just purely something of my own creation do dabble in at home. So the project would essentially represent a simple game idea I have. The game would consist roughly these things: Data structures to hold specific information (would be strongly typed). A way to output the gamestate for the players. This is completely up in the air, it can be graphical or text based, I don't really care at this point. A way to save off game data for the players in something like a database or file system. A relatively easy way for me to input information and a 'GO' button which processes the changes and obviously creates a new gamestate. The game would function similar to a board game. Really nothing out of the ordinary when I look back at that list. Would this be a fun way to learn Python or should I select another language?

• Getting XML Numbered Entities with PHP 5 DOM

  - by user343607

  Hello guys, I am new here and got a question that is tricking me all day long. I've made a PHP script, that reads a website source code through cURL, then works with DOMDocument class in order to generate a sitemap file. It is working like a charm in almost every aspect. The problem is with special characters. For compatibility reasons, sitemap files needs to have all special chars encoded as numbered entities. And I am not achieving that. For example, one of my entries - automatically read from site URLs, and wrote to sitemap file - is: http://www.somesite.com/serviços/redesign/ On the source code it should looks like: http://www.somesite.com/servi*ç*os/redesign/ Just this. But unfortunately, I am really not figuring it out how to do it. Source code file, server headers, etc... everything is encoded as UTF-8. I'm using DOMDocument and related extensions to build the XML. (Basically, DOMDocument, $obj-createElement, $obj-appendChild). htmlentities gives ç instead of ç str_replace does not work. It makes the character just vanish in the output. I was using $obj-createElement("loc", $url); on my code, and just now I read in PHP manual that I should use $document-createTextNode($page), in order to have entities encoding support. Well, it is not working either. Any idea on how to get unstuck of this? Thanks.

• linq: SQL performance on high loaded web applications

  - by Alex

  I started working with linq to SQL several weeks ago. I got really tired of working with SQL server directly through the SQL queries (sqldatareader, sqlcommand and all this good stuff).  After hearing about linq to SQL and mvc I quickly moved all my projects to these technologies. I expected linq to SQL work slower but it suprisongly turned out to be pretty fast, primarily because I always forgot to close my connections when using datareaders. Now I don't have to worry about it. But there's one problem that really bothers me. There's one page that's requested thousands of times a day. The system gets data in the beginning, works with it and updates it. Primarily the updates are ++ @ -- (increase and decrease values). I used to do it like this UPDATE table SET value=value+1 WHERE ID=@I'd It worked with no problems obviously. But with linq to SQL the data is taken in the beginning, moved to the class, changed and then saved. Stats.registeredusers++; Db.submitchanges(); Let's say there were 100 000 users. Linq will say "let it be 100 001" instead of "let it be increased by 1". But if there value of users has already been increased (that happens in my site all the time) then linq will be like oops, this value is already 100 001. Whatever I'll throw an exception" You can change this behavior so that it won't throw an exception but it still will not set the value to 100 002. Like I said, it happened with me all the time. The stas value was increased twice a second on average. I simply had to rewrite this chunk of code with classic ado net. So my question is how can you solve the problem with linq

  So the other day I was sick of typing out repetetive addTarget:action:forControlEvents:s, and macros are only entertaining for so long, so I did this: @implementation UIControl (xx) -(void)addTarget:(id)target action:(SEL)action { [self addTarget:target action:action forControlEvents:UIControlEventTouchUpInside]; } @end *and simply added it at the top of the .m file in question. Works great of course, but notice the "xx".* What's the best thing to NAME a "quick" Category like this? Annoyingly, it appears you can not leave the xx blank - it would then become an "Extension" (which, incidentally, I don't understand at all). I was thinking maybe: a single underscore the name of the class again identically "quick" perhaps the name of the class in this file (as in "quick extra routines for UIControl in CherryBomb") - so it would be UIControl(CherryBomb), ie, remind you that these extra routines are handy for CherryBomb "x" your or your company's initials (use the same "quick" Category name everywhere) "ThisTextNeverUsedAnywhere" By the way, I've been assuming that Categories only happen in the files that see them (CherryBomb.m in the example) - they do not from then on apply app-wide. ie they only apply where you include the header file (UIControl+NattyStuff) or in the "quick" case only in the file to which one adds the text. (By the way ... it appears you do not actually need to include an interface for such a Category, i.e. you can omit... //you can actually get away without these lines... //#import <UIKit/UIControl.h> //@interface UIControl (x) //-(void)addTarget:(id)target action:(SEL)action; //@end ... that part and it works fine.) For people who love Categories, and who doesn't, what's the answer to this troubling question? What should you name a "quick" Category where the name is never going to be referenced again and is irrelevant? Is "_" a solution?

• PHP Missing Function In Older Version

  - by Umair Ashraf

  My this PHP function converts a datetime string into more readable way to represent passed date and time. This is working perfect in PHP version 5.3.0 but on the server side it is PHP version 5.2.17 which lacks this function. Is there a way I can fix this efficiently? This is not only a function which needs this "diff" function but there are many more. public function ago($dt1) { $interval = date_create('now')->diff(date_create($dt1)); $suffix = ($interval->invert ? ' ago' : '-'); if ($v = $interval->y >= 1) return $this->pluralize($interval->y, 'year') . $suffix; if ($v = $interval->m >= 1) return $this->pluralize($interval->m, 'month') . $suffix; if ($v = $interval->d >= 1) return $this->pluralize($interval->d, 'day') . $suffix; if ($v = $interval->h >= 1) return $this->pluralize($interval->h, 'hour') . $suffix; if ($v = $interval->i >= 1) return $this->pluralize($interval->i, 'minute') . $suffix; return $this->pluralize($interval->s, 'second') . $suffix; }

• Upgrade .NET 1.1 WinForm/Service to what?

  - by Conor

  Hi Folks, We have a current WinForm/Windows Service running in .NET 1.1 out on various customer sites that is getting data from internal systems, transforming it and then calling a Web Service synchronously. This client app will no longer work in Vista or Windows 7 etc.. and its time to update!! I was looking for ideas on what I could do here, I didn't write the App and I have the Business team telling me they want the world but I need to be realistic :) Things the service must be able to do: - Handle multiple formats from internal system and transform to a schema SAP, ERP etc.. - Run silently and just work on customer sites (it does currently albeit .NET 1.1) - The Customers are unable to call our web service from their sites as they are not technical enough. - Upgrade it's self when updates occur (currently don't have this capability) Is there anything I can do here other than upgrade the service to run in .NET and add a few more transformation capabilities e..g they want the customer to be able to give us a flat file, an xml file, a csv and the service transforms it and calls the Web Service? I was hoping in this day and age we could use the Web, but automating this 100% rules it out in my eyes? I could be totally wrong!! Any help would be gratefully appreciated! Cheers. Conor

• lots of backbone views - performance issues?

  - by ksol

  tl;dr: I wonder if having lots (100+ for the moment, potentially up to 1000/2000 or more) of backbone views (as a cell of a table) is too heavy or not The project I'm working on revolves around a planning view. There one row per user that covers 6 hours of a day, each hour splitted in 4 slots of 15mn. This planning is used to add "reservations" when clicking on a slot, and should handle hovering of the correct slots, and also handle when it is NOT possible to make a reservation - ie. prevent user click on an "unavailable" slot. There is many reasons why a slot can't be clicked on: the user is not available at this time, or the user is in a reservation; or the app needs to "force" a delay slot between two reservations. Reservations (a div) are rendered in a slot (a cell of a table), and by toying with dimensions, hovers the right number of slots. All this screen is handled with backbone. So For each slot I'm hovering on, I need to check wether I can do a reservation here or not. As of this moment, I use this by toying with the data attributes on the slots : when a reservation object is added, the slots covered are "enhanced with (among others) the reservation object (the backbone view object). But in some cases I don't quite have a grasp on now, it mixes up, and when the reservation view is removed, the slots are not "cleaned up" : the previous class is not reset correctly. It is probably something I've done wrong or badly, but this is only going to get heavier; I think I should use another class of Backbone views here, but I'm afraid the number of slots and thereof of views objects will be high and cause performance issue. I don't know mush about js perf so I'd like to have some feedback before jumping on that train. Any other advice on how to do this would be quite welcomed too. Thanks for your time. If this is not clear enough, tell me, I'll try and rephrase it.
