• Very long strings as primary keys in a database for caching

  - by Bill Zimmerman

  Hi, I am working on a web app that allows users to create dynamic PDF files based on what they enter into a form (it is not very structured data). The idea is that User 1 enters several words (arbitrary # of words, practically capped of course), for example: A B C D E There is no such string in the database, so I was thinking: Store this string as a primary key in a MySQL database (it could be maybe around 50-100k of text, but usually probably less than 200 words) Generate the PDF file, and create a link to it in the database When the next user requests A B C D E, then I can just serve the file instead of recreating it each time. (simple cache) The PDF is cpu intensive to generate, so I am trying to cache as much as I can... My questions are: Does anyone have any alternative ideas to my approach What will the database performance be like? Is there a better way to design the schema than using the input string as the primary key?

• How can I reuse my javascript code between client and server?

  - by Chris Farmer

  I have some javascript code that includes an ANTLR-generated lexer and parser, and some associated syntax tree evaluation functionality. This code runs in the browser in my web app to support users who author code snippets which process scientific data. Now I'd like to do some additional background processing on the server using the same generated parser. I would prefer not to have to re-implement this stuff in C# and have multiple bits of code that did the exact same thing. Performance isn't as critical to me as eliminating duplication, since this is a background process. So, how can I call into my javascript code from C#? And how can I format my script so that it plays nicely with my .NET web app?

• OAuth on iPhone: using Safari or UIWebView?

  - by athanhcong

  Hi all, When I implement OAuth in iPhone, I have a dilemma to choose Safari or UIWebView to open the Twitter pages for user authentication? I write some advantage and disadvantage of both case: Using UIWebWeb. The disadvantage is users have to enter their credentials in our application. It's maybe risky phishing. The advantage is this approach will not quit our app. Using Safari for user to authenticate (this approach automatically callbacks to our application) Addvantage: less risky. Disadvantage: have to quit our app A good reference link about this: http://fireeagle.yahoo.net/developer/documentation/oauth_best_practice Which approach do you prefer? Any response is appreciate. Thanks.

• Caching web page data, Database or File

  - by Mahdi

  I am creating an RSS reader application that requests the RSS from my server. I mean, the RSS is first downloaded to my server, then application downloads it from my server. I want to create RSS cache for this. And for example, each RSS would be refreshed every 1 minute. So, If 10 users request RSS of example.com in 1 minute, my server will download it only for the first time, and in other 9 requests, RSS will be loaded from cache. My question is, Should I use a Database (MSSQL) for this purpose? or I should use files? I have no limit in Database size nor in file size... EDIT: I'm using ASP.NET for the server.

• Why doesn't Inno Setup compiler set the version info correctly from hudson?

  - by Tim

  If I run Inno Setup compiler from a command line/batch file it creates an exe with the version information in the file name. However, when I run from hudson (same command line) I don't get the version information. Perhaps I am missing something. Is this a known issue? This is the way I am doing it in the iss script file. #define FileVerStr GetFileVersion(SrcApp) EDIT: The env vars are all set for all users - not just my login - so the service has access to everything that the command line build does. EDIT: See my answer for a resolution of this.

  I might be a bit confused and may need your help with this. I'm inside inc/newsletter.php and want to include a library that is inside lib/mailchimp-api-class How do I refer to this class file?

• Ipad, closed environment and threat to privacy

  - by Akshay Bhat

  I had an unusual question about ipad, Since ipad environment is closed and does not allows installation of diagnostic and security related programs. How can then we be sure that any of the software installed on ipad is not infringing upon our privacy by doing stuff such as homing back information, etc. We cant install a packet tracer or any other software to check for attacks on privacy. Also given Apples poor track record (the safari browser was broken in one day), I don't think trusting apple solely would be a good idea. This might not seem to be a big issue but for business users it would be a significant concern.

• prevent multiple login with same login credentials in php

  - by shinod

  My website has premium videos, for which users have to pay to watch it. I am sending a random user name and password to the user's email id when the payment is completed. Then I want to assure no more than one user use that login credentials simultaneously. For that I use a login_status column in database table with login credentials and change it to 1 when one user login and change to 0 when user log out. But the problem is, if the user close browser or network connection loss may happened will not update database. Then login_will be 1 undefinitely and no one can use that login credentials again. Is there any idea to accomplish my task?

• Are fopen/fread/fgets PID-safe in C ?

  - by Jane

  Various users are browsing through a website 100% programmed in C (CGI). Each webpage uses fopen/fgets/fread to read common data (like navigation bars) from files. Would each call to fopen/fgets/fread interefere with each other if various people are browsing the same page ? If so, how can this be solved in C ? (This is a Linux server, compiling is done with gcc and this is for a CGI website programmed in C.) Example: FILE *DATAFILE = fopen(PATH, "r"); if ( DATAFILE != NULL ) { while ( fgets( LINE, BUFFER, DATAFILE ) ) { /* do something */ } }

• How to configure MySQL connection properties with Spring, Hibernate 3.3 and c3p0?

  - by sfussenegger

  I am currently in the process of upgrading an application from Hibernate 3.2 to Hibernate 3.3. I though I'd stick with the default connection pool (Hibernate changed its default from Commons DBCP to c3p0) as I don't have any good reason to choose a non-default pool. At least non but having used DBCP before. The upgrade went pretty much without any problems so far. The only thing I can't get to work is passing properties to the underlying MySQL JDBC4Connection. Up to now, I used DBCP's BasicDataSource.addConnectionProperty(String,String) to pass properties (useUnicode=true, characterEncodin=UTF-8, characterSetResults=UTF-8, zeroDateTimeBehavior=convertToNull). However, I can't find any way to do the same with c3p0 other than including them in the JDBC URL. (That's something I'd like to avoid as I wanna keep the URL configurable without forcing users to include those parameters.) So far, I've tried to use a ConnectionCustomizer without success. Any other suggestions?

• PHP Curl and Loop based on a numeric value

  - by danit

  Im using the Twitter API to collect the number of tweets I've favorited, well to be accurate the total pages of favorited tweets. I use this URL: http://api.twitter.com/1/users/show/username.xml I grab the XML element 'favorites_count' For this example lets assume favorites_count=5 The Twitter API uses this URL to get the favorties: http://twitter.com/favorites.xml (Must be authenticated) You can only get the last 20 favorties using this URL, however you can alter the URL to include a 'page' option by adding: ?page=3 to the end of the favorites URL e.g. http://twitter.com/favorites.xml?page=2 So what I need to do is use CURL (I think) to collect the favorite tweets, but using the URL: http://twitter.com/favorites.xml?page=1 http://twitter.com/favorites.xml?page=2 http://twitter.com/favorites.xml?page=3 http://twitter.com/favorites.xml?page=4 etc... Some kind of loop to visit each URL, and collect the Tweets and then output the cotents. Can anyone help with this: - Need to use CURL to authenticate - Collect the number of pages of tweets (Already scripted this) - Then use a loop to go through each page URL based on the pages value?

• Django: many-to-one fields and data integrity

  - by John

  Let's say that I have a Person who runs an inventory system. Each Person has some Cars, and each Car has a very large number of Parts (thousands, let's say). A Person, Bob, uses a Django form to create a Car. Now, Bob goes to create some Parts. It is only at the form level that Django knows that the Parts belong to some specific Car, and that the Parts.ForeignKey(Car) field should only have a specific Car as a choice. When creating a Part, you have to mess with the form's constructor or similar in order to limit the choice of Cars to only the cars owned by Bob. It does not seem proper that to enforce this ownership at the form level. It seems that other users' Cars must be inaccessible to anyone but the owner of the Car. What do you all think about this, and is there any way to enforce this?

• In search of opinions on web based version control systems

  - by tom smith

  Hi. Researching various open source, web-based document management/version control systems. I've checked google/questions here, etc... I'm looking for a lightweight web-based (apache) document mgmt/version control app that runs on top of SVN. I need to have the ability to: have multiple users checkin/checkout have a workflow (when userA checks the file in, and finishes the app passes it to the next person, etc... the app needs to allow me to have a structure where the files can be moved as a group. the files will be changed on a monthly basis app needs to have a access/premission control system. some people can see certain files, and perform certain actions on the files I imagine that I'm going to have 40-50 people dealing with the different files. I imagine that I'm going to have 2000-3000 files that have to be massaged. I'd prefer that the app be php based if possible, as opposed to a straight java app. Thanks

• how to hide table columns in jQuery?

  - by understack

  I've a table with lots of columns. I want to give users the option to select columns to be shown in table. These options would be checkboxes along with the column names. So how can I hide/unhide table columns based on checkboxes? Would hiding (using .hide()) each td in each row work? May be I can assign checkbox value to the location of column in table. So first checkbox means first column and so on. And then recursively hide that 'numbered' td in each row. Would that work?

• C# application per-machine/per-user licensing

  - by MainMa

  Hi, I am about to implement a very basic licensing feature for my application. A serial number may be granted per-machine (or per-operating-system) or per-user (as for CAL in Windows Server: if my application is used by several users on one machine or if it is used by one user on several machines). For per-operating-system licensing, I use SerialNumber of Win32_OperatingSystem. For per-user licensing, I use: WindowsIdentity currentIdentity = WindowsIdentity.GetCurrent(); if (currentIdentity != null) { SecurityIdentifier userSid = currentIdentity.User.AccountDomainSid; Console.WriteLine(userSid); } A hash of an obtained OS serial number or SID is then stored in the database, associated with application serial; each time the program starts, it queries the server, sending hash of OS SN/SID and application serial. Is it a right thing to do it or is it completely wrong? Will it work on every Windows machine? (For example, using motherboard serial is wrong)

• Animating a font size change in a UITableView

  - by nickthedude

  Hey Simple little app for educational purposes, its a simple uitableview and I want users to be able to use a uislider to adjust the font size as needed. The code I have now works to change the font but only when the view is updated, ie when i pull up or down the table view to reveal other cells. I'd like the font change to be reflected immediately as a user moves the uislider if possible, here's the code that I have working half way: -(UITableViewCell *) tableView: (UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *) indexPath { static NSString *SimpleTableIdentifier = @"SimpleTableIdentifier"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier: SimpleTableIdentifier]; if (cell == nil) cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier: SimpleTableIdentifier] autorelease]; NSUInteger row = [indexPath row]; cell.text = [listData objectAtIndex:row]; UIImage *image = [UIImage imageNamed:@"star.png"]; cell.font = [UIFont systemFontOfSize:[fontSlider value]]; cell.image = image; return cell; }

• JQuery or javascript to find memory usage of page

  - by Tauren

  Is there a way to find out how much memory is being used by a web page, or by my jquery application? Here's my situation: I'm building a data heavy webapp using a jquery frontend and a restful backend that serves data in JSON. The page is loaded once, and then everything happens via ajax. The UI provides users with a way to create multiple tabs within the UI, and each tab can contain lots and lots of data. I'm considering limiting the number of tabs they can create, but was thinking it would be nice to only limit them once memory usage has gone above a certain threshold.

• Help with complex sql query

  - by eugeneK

  To make story short, i'm building self-learning banner management system. Users will be able to insert these banners to their site when banners will be shown based on sales/impressions ratio. I have 4 tables Banners bannerID int bannerImage varchar.... SmartBanners smartBannerID int smartBannerArrayID int bannerID int impressionsCount int visibility tinyint (percents) SmartBannerArrays smartBannerArrayID int userID int Statistics bannerID int saleAmountPerDay decimal... Each night i need to generate new "visibility" for each SmartBanner based on whole SmartBannerArray that same user has. So i need to get sum of impressions and sales for each bannerID in SmartBannerArray. All comes to my mind is to use double cursor, one will loop thought SmartBannerArrays get needed values for sum of impressions and sales and then inner loop which will access each SmartBanner and change it's "visibility" percentage based on (sales/impressions)/(sumOfSales/sumOfImpressions)*100 Hope you get the picture... Is there any other way to design better tables or not to use double cursor to avoid server overload ?

• What's the easiest/fast way to get my website up and running on the web?

  - by ggfan

  This is probably a really really beginner's question, but I would like to know what's the fastest way to get my site on the web so that people can start using it. I'm learning everything about programming out of books and at home so I don't have much experience. --Before I go to like godaddy.com or such site to get a domain name, is there any free sites that would allow me to upload my site so users can use it? I have html,css,php,mysql,javascipt in my scripts so I don't think many sites allow free uploads with such languages. --If I can't find a free site, is there any good places to get a domain name and web hosting that supports most languages at a low price? (doesn't have to be professional hosting because I am still a beginner) --If I go to say godaddy.com and get their webhosting and domain name, would I be allowed to run php,mysql,python,java on it? (I looked at some hosting sites and most only allow php/mysql)

• Using persistent and non-persistent connection together in a PHP MySQL app

  - by cappuccino

  There are parts of my app where a persistent connection is required, in particular the parts where every hour maybe 30,000 select requests are made by many different users, this is causing my mysql server to max out on the 100 connection limit, and i really don't want to increase it since 100 connections already seems like alot. So for the parts of the application where reading and selecting is the case I want to switch to persistent connections. The other parts where data is being modified is usually done through a transaction, and the general rule is never to use persistent connections for transactions according to the php documentation. So I would like to keep this on non-persistent connections. My question is, am i able to use persistent and non-persistent connections together in the same app, the same script etc? I am using PHP 5.2+, MySQL 5+ (InnoDB tables) and the Zend Framework 10.6+

• Can SVG render partially if gzipped and chunk-transferred?

  - by Scott Stafford

  Hi - I have some large, dynamically generated SVGs that are being served over a relatively slow internet connection. I'm trying to optimize them to be viewable as fast as possible. If I set the server to Content-Encoding: gzip and Transfer-Encoding: chunked, will any SVG viewers take advantage of that and render it partially, as it is transferred? If not, are there other ways to get it to render as-it-streams? I could break it up into several SVG pieces but that will be a lot of work, I was hoping for server settings... The most common users use IE7 with the Adobe SVG Viewer plugin. I doubt it matters but I'm serving with C#/ASP.NET and IIS6.
