• Why do I get "Error 6060" when I try to use DBD::Advantage with a 64-bit perl on Linux?

  - by WarheadsSE

  I realize that I am attempting to go beyond the "supported" behavior of the manf's released drivers for Perl, after all they have only released it in package with x86 .so's. However, since I cannot use their package with x64 Perl on a RHEL 5.4 x86_64 box, and maintaining a seperate install of x86 Perl just for this one package, I have made an attempt to get this puppy working thanks to released 64-bit .so's that accompany other driver packages for Advantage. What I have done to this point: download beta 10 DBI drivers, in 32 download beta 10 PHP extension (it contains 32 and x86_64) copy the required DLLs into the ads-lib location (eg /usr/local/ads/lib64) compile the Perl DBI driver with the path to the lib64's .so's Good compilation, good install, good use. The problem is that I always get : failed: [iAnywhere Solutions][Advantage SQL][ASA] Error 6060: Advantage Database Server not available on specified server. axServerConnect (SQL-HY000)(DBD: db_login/SQLConnect err=-1) Does anyone have any ideas? EDIT: fixed package name in post title EDIT: Updated title. It appears that it's not just the x64 perl, but the RHEL 5.4 underneath that may be interfering. As commented below, I managed to shoe-horn a x86 perl onto the system, and compile the DBD::Advantage 9.99, and later replacing that with 9.10, and none of these x86 would connect either. Neither library (9.99 or 9.10) in either bit-edness will connect from this x86_64 server to the windows server's UNC path. I have successfully mounted this share without problems, but still I cannot seem to connect to the 9.1. I have tried: \hostname\PATH \FQDN\PATH \IP\PATH and all of these variations with the port (default) 6262 included. My windows machine connects fine, with both 9.1 and 9.99 from strawberry perl.

• Excel VBA SQL Import

  - by user307655

  Hi All, I have the following code which imports data from a spreadsheet to SQL directly from Excel VBA. The code works great. However I am wondering if somebody can help me modify the code to: 1) Check if data from column A already exists in the SQL Table 2) If exists, then only update rather than import as a new role 3) if does not exist then import as a new role. Thanks again for your help Sub SQLIM() ' Send data to SQL Server ' This code loads data from an Excel Worksheet to an SQL Server Table ' Data should start in column A and should be in the same order as the server table ' Autonumber fields should NOT be included' ' FOR THIS CODE TO WORK ' In VBE you need to go Tools References and check Microsoft Active X Data Objects 2.x library Dim Cn As ADODB.Connection Dim ServerName As String Dim DatabaseName As String Dim TableName As String Dim UserID As String Dim Password As String Dim rs As ADODB.Recordset Dim RowCounter As Long Dim ColCounter As Integer Dim NoOfFields As Integer Dim StartRow As Long Dim EndRow As Long Dim shtSheetToWork As Worksheet Set shtSheetToWork = ActiveWorkbook.Worksheets("Sheet1") Set rs = New ADODB.Recordset ServerName = "WIN764X\sqlexpress" ' Enter your server name here DatabaseName = "two28it" ' Enter your database name here TableName = "COS" ' Enter your Table name here UserID = "" ' Enter your user ID here ' (Leave ID and Password blank if using windows Authentification") Password = "" ' Enter your password here NoOfFields = 7 ' Enter number of fields to update (eg. columns in your worksheet) StartRow = 2 ' Enter row in sheet to start reading records EndRow = shtSheetToWork.Cells(Rows.Count, 1).End(xlUp).Row ' Enter row of last record in sheet ' CHANGES ' Dim shtSheetToWork As Worksheet ' Set shtSheetToWork = ActiveWorkbook.Worksheets("Sheet1") '** Set Cn = New ADODB.Connection Cn.Open "Driver={SQL Server};Server=" & ServerName & ";Database=" & DatabaseName & _ ";Uid=" & UserID & ";Pwd=" & Password & ";" rs.Open TableName, Cn, adOpenKeyset, adLockOptimistic For RowCounter = StartRow To EndRow rs.AddNew For ColCounter = 1 To NoOfFields rs(ColCounter - 1) = shtSheetToWork.Cells(RowCounter, ColCounter) Next ColCounter Next RowCounter rs.UpdateBatch ' Tidy up rs.Close Set rs = Nothing Cn.Close Set Cn = Nothing End Sub

• Testing Async downloads with ASIHTTPRequest

  - by Baishampayan Ghose

  I am writing a simple library using ASIHTTPRequest where I am fetching URLs in an async manner. My problem is that the main function that I have written to test my lib exits before the async calls are finished. I am very new to Obj C and iPhone development, can anyone suggest a good way to wait before all the requests are finished in the main function? Currently, my main function looks like this - int main(int argc, char *argv[]) { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; IBGApp *ibgapp = [[IBGApp alloc] init]; IBGLib *ibgl = [[IBGLib alloc] initWithUsername:@"joe" andPassword:@"xxx"]; // The two method calls below download URLs async. [ibgl downloadURL:@"http://yahoo.com/" withRequestDelegate:ibgapp andRequestSelector:@selector(logData:)]; [ibgl downloadURL:@"http://google.com/" withRequestDelegate:ibgapp andRequestSelector:@selector(logData:)]; [pool release]; return 0; // I reach here before the async calls are done. } So what is the best way to wait till the async calls are done? I tried putting sleep, but obviously doesn't work.

• How to determine which source files are required for an Eclipse run configuration

  - by isme

  When writing code in an Eclipse project, I'm usually quite messy and undisciplined in how I create and organize my classes, at least in the early hacky and experimental stages. In particular, I create more than one class with a main method for testing different ideas that share most of the same classes. If I come up with something like a useful app, I can export it to a runnable jar so I can share it with friends. But this simply packs up the whole project, which can become several megabytes big if I'm relying on large library such as httpclient. Also, if I decide to refactor my lump of code into several projects once I work out what works, and I can't remember which source files are used in a particular run configuration, all I can do it copy the main class to a new project and then keep copying missing types till the new project compiles. Is there a way in Eclipse to determine which classes are actually used in a particular run configuration? EDIT: Here's an example. Say I'm experimenting with web scraping, and so far I've tried to scrape the search-result pages of both youtube.com and wrzuta.pl. I have a bunch of classes that implement scraping in general, a few that are specific to each of youtube and wrzuta. On top of this I have a basic gui common to both scrapers, but a few wrzuta- and youtube-specific buttons and options. The WrzutaGuiMain and YoutubeGuiMain classes each contain a main method to configure and show the gui for each respective website. Can Eclipse look at each of these to determine which types are referenced?

• yahoo's attribute exchange -> blank data is coming

  - by Gaurav Sharma

  Hello everybody, I am trying to build openid login system for my website. To do this I used JanRain's php openid library v 2.1.3. I am also using openid selector to select the openid provider from the list. I first created the attributes array that I need to fetch from the provider as follows: $attribute[] = Auth_OpenID_AX_AttrInfo::make('http://axschema.org/contact/email',2,1, 'email'); $attribute[] = Auth_OpenID_AX_AttrInfo::make('http://axschema.org/namePerson/first',1,1, 'firstname'); $attribute[] = Auth_OpenID_AX_AttrInfo::make('http://axschema.org/namePerson/last',1,1, 'lastname'); $attribute[] = Auth_OpenID_AX_AttrInfo::make('http://axschema.org/namePerson',1,1, 'fullname'); $attribute[] = Auth_OpenID_AX_AttrInfo::make('http://axschema.org/namePerson/friendly',1,1, 'username'); $ax = new Auth_OpenID_AX_FetchRequest; foreach($attribute as $attr) { $ax-add($attr); } $auth_request-addExtension($ax); and in the finish_auth.php file I wrote this to fetch the attributes returned $ax = new Auth_OpenID_AX_FetchResponse(); $obj = $ax-fromSuccessResponse($response); Google gives me all the attributes requested but yahoo doesn't (as stated here that yahoo now supports attribute exchange). Is there any limitation set by yahoo on attribute exchange too. (they give limited websites access to sreg extension of openid). :( Please help me, I am stuck over here. Thanks

• What options to parse a DTD using PHP

  - by Chadwick

  I need to parse DTDs using PHP and am hoping there's a simple library to help out. Each DTD has numerous <!ENTITY... and <!-- Comment... elements, which I need to act upon. Note that I do not need to validate anything against these DTDs, simply parse them as data files themselves. A few options I've looked at: James Clarke's SD, which is an option of last resort, but I'd like to avoid the complexity of building/installing/configuring code external to PHP. I'm not sure it's even possible in my situation. PEAR has an XML_DTD_Parser, which requires installing/configuring PEAR and a number of pear modules, which I'm also not sure is possible, and would rather avoid. Has anyone used it with success? PHP XML Classes has the class_path_parser, which another site suggested, but it fails to read ENTITY elements. It appears to be using PHP's built in XML parsing capabilities, which use EXPAT. PHP's DOMDocument will validate against a DTD, so must be able to read them, though I don't see how to get at the DTD parser directly at first glance.

• What is the best software design to use in this scenario

  - by domdefelice

  I need to generate HTML snippets using jQuery. The creation of those snippets depends on some data. The data is stored server-side, in session (where PHP is used). At the moment I achieved this - retrieving the data from the server via AJAX in form of JSON - and building the snippets via specific javascript functions that read those data The problem is that the complexity of the data is getting bigger and hence the serialization into JSON is getting even more difficult since I can't do it automatically. I can't do it automatically because some information are sensible so I generate a "stripped" version to send to the client. I know it is difficult to understand without any code to read, but I am hoping this is a common scenario and would be glad for any tip, suggestion or even design-pattern you can give me. Should I store both a complete and a stripped data on the server and then use some library to automatically generate the JSON from the stripped data? But this also means I have to get the two data synchronized. Or maybe I could move the logic server-side, this way avoiding sending the data. But this means sending javascript code (since I rely on jQuery). Maybe not a good idea. Feel free to ask me more details if this is not clear. Thank you for any help

• Rendering LaTeX on third-party websites?

  - by A. Rex

  There are some sites on the web that render LaTeX into some more readable form, such as Wikipedia, some Wordpress blogs, and MathOverflow. They may use images, MathML, jsMath, or something like that. There are other sites on the web where LaTeX appears inline and is not rendered, such as the arXiv, various math forums, or my email. In fact, it is quite common to see an arXiv paper's abstract with raw LaTeX in it, e.g. this paper. Is there a plugin available for Firefox, or would it be possible to write one, that renders LaTeX within pages that do not provide a rendering mechanism themselves? (The LaTeX would be enclosed within dollar signs, e.g. $\pi$. See the arXiv link above.) Some notes: It may be impossible to render some of the code, because authors often copy-paste code directly from their source TeX files, which may contain things like "\cite{foo}" or undefined commands. These should be left alone. This question is a repost of a question from MathOverflow that was closed for not being related to math. There is one answer there, which is helpful, but perhaps Stack Overflow can provide better answers. I program a lot, but Javascript is not my specialty, so comments along the lines of "look at this library" are not particularly helpful to me (but may be to others).

• Can't send an email using a google apps account with PHPMailer

  I'm trying to simply send an email using my google apps account with php. I am able to send an email in a .net application using the port 587 host smtp.googlemail.com and SSL enabled. The username is my full email address. require_once('PHPMailer_v5.1\class.phpmailer.php'); try { $mail = new PHPMailer(); $mail->Mailer = 'smtp'; $mail->SMTPSecure = 'tls'; $mail->Host = $host; $mail->Port = 587; $mail->SMTPAuth = true; $mail->Username = $from; $mail->Password = $password; $mail->AddAddress($to, $to_name); $mail->From = $from; $mail->FromName = $from_name; $mail->Subject = $subject; $mail->MsgHTML($body); $mail->IsHTML(true); $mail->Send(); } catch (phpmailerException $e) { echo $e->errorMessage(); } catch (Exception $e) { echo $e->getMessage(); } Haven't been able to get this to work, but I've tried several different variations of this. $mail->SMTPSecure = 'ssl'; // Error: Could not connect to SMTP host. $mail->SMTPSecure = 'tls'; // Takes forever, then I get "this stream does not support SSL/crypto PHPMailer_v5.1\class.smtp.php" I don't care how, but I need to send an email using gmail here. It can be with this library or a different one.

• What's the Matlab equivalent of NULL, when it's calling COM/ActiveX methods?

  - by David M

  Hi, I maintain a program which can be automated via COM. Generally customers use VBS to do their scripting, but we have a couple of customers who use Matlab's ActiveX support and are having trouble calling COM object methods with a NULL parameter. They've asked how they do this in Matlab - and I've been scouring Mathworks' COM/ActiveX documentation for a day or so now and can't figure it out. Their example code might look something like this: function do_something() OurAppInstance = actxserver('Foo.Application'); OurAppInstance.Method('Hello', NULL) end where NULL is where in another language, we'd write NULL or nil or Nothing, or, of course, pass in an object. The problem is this is optional (and these are implemented as optional parameters in most, but not all, cases) - these methods expect to get NULL quite often. They tell me they've tried [] (which from my reading seemed the most likely) as well as '', Nothing, 'Nothing', None, Null, and 0. I have no idea how many of those are even valid Matlab keywords - certainly none work in this case. Can anyone help? What's Matlab's syntax for a null pointer / object for use as a COM method parameter? Update: Thanks for all the replies so far! Unfortunately, none of the answers seem to work, not even libpointer. The error is the same in all cases: Error: Type mismatch, argument 2 This parameter in the COM type library is described in RIDL as: HRESULT _stdcall OurMethod([in] BSTR strParamOne, [in, optional] OurCoClass* oParamTwo, [out, retval] VARIANT_BOOL* bResult); The coclass in question implements a single interface descending from IDispatch.

• How to setup a Zend_Application with an application.ini and a user.ini

  - by Peter Smit

  I am using Zend_Application and it does not feel right that I am mixing in my application.ini both application and user configuration. What I mean with this is the following. For example, my application needs some library classes in the namespace MyApp_ . So in application.ini I put autoloaderNamespaces[] = "MyApp_". This is pure application configuration, no-one except a programmer would change these. On the other hand I put there a database configuration, something that a SysAdmin would change. My idea is that I would split options between an application.ini and an user.ini, where the options in user.ini take preference (so I can define standard values in application.ini). Is this a good idea? How can I best implement this? The idea's I have are Extending Zend_Application to take multiple config files Making an init function in my Bootstrap loading the user.ini Parsing the config files in my index.php and pass these to Zend_Application (sounds ugly) What shall I do? I would like to have the 'cleanest' solution, which is prepared for the future (newer ZF versions, and other developers working on the same app)

• Why is OpenSubKey() returning null on my Win 7 64 bit system?

  - by BrMcMullin

  Has anyone seen OpenSubKey() and other Microsoft.Win32 registry functions return null on 64 bit systems when 32 bit registry keys are under Wow6432node in the registry? I'm working on a unit testing framework that makes a call to OpenSubKey() from the .net library. My dev system is a Win 7 64 bit environment with VS 2008 SP1 and the Win 7 SDK installed. The application we're unit testing is a 32 bit application, so the registry is virtualized under HKLM\Software\Wow6432node. When we call: Registry.LocalMachine.OpenSubKey( @"Software\MyCompany\MyApp\" ); Null is returned, however explicitly stating to look here works: Registry.LocalMachine.OpenSubKey( @"Software\Wow6432node\MyCompany\MyApp\" ); From what I understand this function should be agnostic to 32 bit or 64 bit environments and should know to jump to the virtual node. Even stranger is the fact that the exact same call inside a compiled and installed version of our application is running just fine on the same system and is getting the registry keys necessary to run; which are also being placed in HKLM\Software\Wow6432node. Any suggestions? Thanks in advance!

• Updating a DLL in a Production ASP.NET Web Site bin folder

  - by Josh Stodola

  I want to update a class library (a single DLL file) in a production web application. This web app is pre-compiled (published). I read an answer on StackOverflow (sorry, can't seem to find it anymore because the Search function does not work very well), that led me to believe that I could just paste the new DLL in the bin folder and it would be picked up without problems (this would cause the WP to recycle, which is fine with me because we do not use InProc session state). However, when I tried this, my site blows up and gives a FileLoadException saying that the assembly manifest definition does not match the assembly reference. What in the world is this?! Updating the DLL in Visual Studio and re-deploying the entire site works just fine, but it is a huge pain in the rear. What is the point of having a separate DLL if you have to re-deploy the entire site to implement any changes? Here's the question: How can I update a DLL on a production web site without breaking the app and without re-deploying all of the files?

• How to write a custom solution using a python package, modules etc

  - by morpheous

  I am writing a packacge foobar which consists of the modules alice, bob, charles and david. From my understanding of Python packages and modules, this means I will create a folder foobar, with the following subdirectories and files (please correct if I am wrong) foobar/ __init__.py alice/alice.py bob/bob.py charles/charles.py david/david.py The package should be executable, so that in addition to making the modules alice, bob etc available as 'libraries', I should also be able to use foobar in a script like this: python foobar --args=someargs Question1: Can a package be made executable and used in a script like I described above? Question 2 The various modules will use code that I want to refactor into a common library. Does that mean creating a new sub directory 'foobar/common' and placing common.py in that folder? Question 3 How will the modules foo import the common module ? Is it 'from foobar import common' or can I not use this since these modules are part of the package? Question 4 I want to add logic for when the foobar package is being used in a script (assuming this can be done - I have only seen it done for modules) The code used is something like: if __name__ == "__main__": dosomething() where (in which file) would I put this logic ?

• XML comments on delegate declared events

  - by Matt Whitfield

  I am visiting some old code, and there are quite a few events declared with delegates manually rather than using EventHandler<T>, like this: /// <summary> /// Delegate for event Added /// </summary> /// <param name="index">Index of the item</param> /// <param name="item">The item itself</param> public delegate void ItemAdded(int index, T item); /// <summary> /// Added is raised whenever an item is added to the collection /// </summary> public event ItemAdded Added; All well and good, until I come to use sandcastle to document the library, because it then can't find any XML comments for the private Added field that is generated by the event declaration. I want to try and sort that out, but what I would like to do is either: Get sandcastle to ignore the auto-generated private field without telling it to ignore all private fields entirely or Get XML comments generated for the private field Is there any way of achieving this without re-factoring the code to look like this: /// <summary> /// Delegate for event <see cref="Added"/> /// </summary> /// <param name="index">Index of the item</param> /// <param name="item">The item itself</param> public delegate void ItemAdded(int index, T item); /// <summary> /// Private storage for the event firing delegate for the <see cref="Added"/> event /// </summary> private ItemAdded _added; /// <summary> /// Added is raised whenever an item is added to the collection /// </summary> public event ItemAdded Added { add { _added += value; } remove { _added -= value; } }

• How can I round money values to the nearest $5.00 interval?

  - by Frank Developer

  I have an Informix-SQL based Pawnshop app which calculates an estimate of how much money should be loaned to a customer, based on the weight and purity of gold. The minimum the pawnshop lends is $5.00. The pawnshop employee will typically lend amounts which either ends with a 5 or 0. examples: 10, 15, 20, 100, 110, 125, etc. They do this so as to not run into shortage problems with $1.00 bills. So, if for example my system calculates the loan should be: $12.49, then round it to $10, $12.50 to $15.00, $13.00 to $15.00, $17.50 to $20.00, and so on!..The employee can always override the rounded amount if necessary. Is it possible to accomplish this within the instructions section of a perform screen or would I have to write a cfunc and call it from within perform?.. Are there any C library functions which perform interval rounding of money values?.. On another note, I think the U.S. Government should discontinue the use of pennies so that businesses can round amounts to the nearest nickel, it would save so much time and weight in our pockets!

• In IIS6, how to provide authenticated access to static files on remote server

  - by frankadelic

  We have a library of ZIP files that we would like to make available for download at an ASP.NET site. The files are sitting on a NAS device that is accessible from out web farm. Here is our initial strategy: Map an IIS virtual directory to the shared drive at path /zipfiles Users can download the zip files when given the URL However, if users share links to the files, anyone can download them. We would instead like to make use of the ASP.NET forms authentication in our site to validate users' requests before initiating the file transfer. A few problems: A request for a zip file is handled by IIS, not ASP.NET. So it is not subject to forms authentication. In addition, we don't want ASP.NET to handle the request, because it uses up an ASP.NET thread and is not scalable for download of large files. So, configuring the asp.net dll to handle *.zip requests is not an option. Any ideas on this? One idea we've tossed around is this: Initial request for download will be for an ashx handler. This handler will, after authentication, generate a download token which is saved to a database. Then, the user is redirected to the file with token appended in QueryString (e.g. /files/xyz.zip?token=123456789). An ISAPI plugin will be used to check the token. Also, the token will expire after x amount of time. Any thoughts on this? I have not implemented an ISAPI plugin so I'm not sure if this will even work. I would like to avoid custom coding since security is an issue and I'd prefer to use a time-tested solution.

• ProgressDialog does not display until after AsyncTask completes

  - by tedwards

  I am trying to display an indefinite ProgressDialog, while an AsyncTask binds to a RemoteService. The RemoteService builds a list of the users contacts when the service is first created. For a long list of contacts this may take 5~10 seconds. The problem I am having, is that the ProgressDialog does not display until after the RemoteService has built it's list of contacts. I even tried putting a Thread.sleep in to give the ProgressDialog time to show up. With the sleep statement the ProgressDialog loads and starts spinning, but then locks up as soon as the RemoteService starts doing it's work. If I just turn the AsyncTask into dummy code, and just let it sleep for a while, everything works fine. But when the task has to do actual work, it is like the UI just sits and waits. Any ideas on what Im doing wrong ? @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Log.d(IM,"Start Me UP!!"); setContentView(R.layout.main); Log.d(IM, "Building List View for Contacts"); restoreMe(); if (myContacts==null){ myContacts = new ArrayList<Contact>(); this.contactAdapter = new ContactAdapter(this, R.layout.contactlist, myContacts); setListAdapter(this.contactAdapter); new BindAsync().execute(); } else{ this.contactAdapter = new ContactAdapter(this, R.layout.contactlist, myContacts); setListAdapter(this.contactAdapter); } } private class BindAsync extends AsyncTask<Void, Void, RemoteServiceConnection>{ @Override protected void onPreExecute(){ super.onPreExecute(); Log.d(IM,"Showing Dialog"); showDialog(DIALOG_CONTACTS); } @Override protected RemoteServiceConnection doInBackground(Void... v) { Log.d(IM,"Binding to service in BindAsync"); try{ Thread.sleep(2000); } catch (InterruptedException e){ } RemoteServiceConnection myCon; myCon = new RemoteServiceConnection(); Intent i = new Intent(imandroid.this,MyRemoteService.class); bindService(i, myCon, Context.BIND_AUTO_CREATE); startService(i); Log.d(IM,"Bound to remote service"); return myCon; } @Override protected void onPostExecute(RemoteServiceConnection newConn){ super.onPostExecute(newConn); Log.d(IM,"Storing remote connection"); conn=newConn; } };

• How should I implement lazy session creation in PHP?

  - by Adam Franco

  By default, PHP's session handling mechanisms set a session cookie header and store a session even if there is no data in the session. If no data is set in the session then I don't want a Set-Cookie header sent to the client in the response and I don't want an empty session record stored on the server. If data is added to $_SESSION, then the normal behavior should continue. My goal is to implement lazy session creation behavior of the sort that Drupal 7 and Pressflow where no session is stored (or session cookie header sent) unless data is added to the $_SESSION array during application execution. The point of this behavior is to allow reverse proxies such as Varnish to cache and serve anonymous traffic while letting authenticated requests pass through to Apache/PHP. Varnish (or another proxy-server) is configured to pass through any requests without cookies, assuming correctly that if a cookie exists then the request is for a particular client. I have ported the session handling code from Pressflow that uses session_set_save_handler() and overrides the implementation of session_write() to check for data in the $_SESSION array before saving and will write this up as library and add an answer here if this is the best/only route to take. My Question: While I can implement a fully custom session_set_save_handler() system, is there an easier way to get this lazy session creation behavior in a relatively generic way that would be transparent to most applications?

• code igniter codeigniter question, making anchor load page containing data from referenced row in DB

  - by thrice801

  Hi, Im trying to learn the code igniter library and object oriented php in general and have a question. Ok so Ive gotten as far as making a page which loads all of the rows from my database and in there, Im echoing an anchor tag which is a link to the following structure. [code]echo anchor("videos/video/$row-video_id", $row-video_title);[/code] So, I have a class called Videos which extends the controller, within that class there is index and video, which is being called correctly (when you click on the video title, it sends you to videos/video/5 for example, 5 being the primary key of the table im working with. So basically all Im trying to do is pass that 5 back to the controller, and then have the particular video page output the particular rows data from the videos table. My function in my controller for video looks like this - [code] function video() { $data['main_content'] = 'video'; $data['video_title'] = 'test'; $this-load-view('includes/template', $data); } [/code] So ya, basically test should be instead of test, a returned value of a query which says get in the table "videos", the row with the video_id of "5", and make $data['video_title'] = value of video_title in database... Should have this figured out by now but dont, any help would be appreciated!

• S3 Backup Memory Usage in Python

  - by danpalmer

  I currently use WebFaction for my hosting with the basic package that gives us 80MB of RAM. This is more than adequate for our needs at the moment, apart from our backups. We do our own backups to S3 once a day. The backup process is this: dump the database, tar.gz all the files into one backup named with the correct date of the backup, upload to S3 using the python library provided by Amazon. Unfortunately, it appears (although I don't know this for certain) that either my code for reading the file or the S3 code is loading the entire file in to memory. As the file is approximately 320MB (for today's backup) it is using about 320MB just for the backup. This causes WebFaction to quit all our processes meaning the backup doesn't happen and our site goes down. So this is the question: Is there any way to not load the whole file in to memory, or are there any other python S3 libraries that are much better with RAM usage. Ideally it needs to be about 60MB at the most! If this can't be done, how can I split the file and upload separate parts? Thanks for your help. This is the section of code (in my backup script) that caused the processes to be quit: filedata = open(filename, 'rb').read() content_type = mimetypes.guess_type(filename)[0] if not content_type: content_type = 'text/plain' print 'Uploading to S3...' response = connection.put(BUCKET_NAME, 'daily/%s' % filename, S3.S3Object(filedata), {'x-amz-acl': 'public-read', 'Content-Type': content_type})

• jquery anchor to html extract

  - by Benjamin Ortuzar

  I would like to implement something similar to the Google quick scroll extension with jquery for the extracts of a search result, so when the full document is opened (within the same website) it gives the user the opportunity to go straight to the extract location. Here is a sample of what I get returned from the search engine when I search for 'food'. <doc> <docid>129305</docid> <title><span class='highlighted'>Food</span></title> <summary> <summarytext>Papers subject to Negative Resolution: 4 <span class='highlighted'>Food</span> <span class='highlighted'>Food</span> Irradiation (England) Regulations 2009 (S.I., 2009, No. 1584), dated 24 June 2009 (by Act), </summarytext> </summary> <paras> <paraitemcount>2</paraitemcount> <para> <paraitem>1</paraitem> <paraid>42</paraid> <pararelevance>100</pararelevance> <paraweights>50</paraweights> <paratext>4 <span class='highlighted'>Food</span></paratext> </para> <para> <paraitem>2</paraitem> <paraid>54</paraid> <pararelevance>100</pararelevance> <paraweights>50</paraweights> <paratext><span class='highlighted'>Food</span> Irradiation (England) Regulations 2009 (S.I., 2009, No. 1584), dated 24 June 2009 (by Act), with an Explanatory Memorandum and an Impact Assessment (</paratext> </para> </paras> </doc> As you see the search engine has returned a document that contains one summary and two extracts. So let's say the user clicks on the second extract in the search resutls page, the browser would open the detailed document in the same website, and would offer the user the possibility to go to the extract as the Google quick scroll extension does. Is there an existing jquery script for this? If not, can you suggest any jquery/javascript code that would simplify my task to implement this. Notes: I can access the extracts from the document details page. I'm aware that the HTML in some cases could be slightly different in the extract than in the details page, finding no match. The search engine does not return where the extract was located. At the moment I'm trying to understand the JS code that the extension uses.
