  • jquery block UI malfunction on ajax loading event

    - by Ygam
    problem: trigger errored when block UI is called on this code (function($){ function preloader() { $('a#preloader').click(function(e){ e.preventDefault(); var url = base_url + 'runtest/preloader'; $('div#content').load(url, preloaderCallback); }); } function remotePreload() { $('a#remotepreload').click(function(e){ e.preventDefault(); var object = $(this); object.data('clicked', 'yes'); var url = base_url + 'runtest/remote_preloader'; $('div#content').load(url); }); } /* * callback functions */ function preloaderCallback() { $('div.imageholder img').hide(); $('div.imageholder img').each(function(){ var img = new Image(); var sursa = $(this).attr('src'); var parent = $(this).parent(); var preloaderSource = '<img src="' + base_url + 'media/images/preloader.gif' + '" alt="loader"/>'; parent.append(preloaderSource); $(img).load(function(){ parent.append($(this)); $(this).hide().fadeIn(500); $(this).siblings().remove(); }).attr('src', sursa); }); } function blocker() { $('#content').block(); } function handlePageLoad() { $('a#remotepreload').ajaxStart(function(e){ var elem = $(e.target); if (elem.data('clicked') == 'yes') { // error when blocker() function is called here alert('Started'); } }); $('a#remotepreload').ajaxComplete(function(e){ var elem = $(e.target); if (elem.data('clicked') == 'yes') { elem.removeData('clicked'); alert('Ended'); } }); } // call onready functions $(function(){ preloader(); remotePreload();handlePageLoad(); }); })(jQuery); // here's the error from firefox's debugger uncaught exception: [Exception...

  • hex value in field/row terminator for bulk insert

    - by TheObserver
    I'm running SQL Server 2005 Express. And I'm trying to do a bulk insert/import of a data file with a field/row terminator that uses a hexadecimal value 0x001. How should I represent it in a bulk insert command? I have something like: bulk insert xxx.dbo.[yyy] from 'D:\zzz\zzz.dat' with ( CODEPAGE='RAW', FIELDTERMINATOR = '=|=', ROWTERMINATOR = '=|=\001\n', KEEPNULLS ); which results in Msg 4863, Level 16, State 1, Line 7 Bulk load data conversion error (truncation) for row 1, column 3 (code).

  • All embedded databases fail to open connections

    - by rsteckly
    Hi, I'm working on a winforms desktop application that needs to store data. I made the really bad decision to try and embed a database. I've tried: SQLite VistaDB SQL Server Compact In each case, I was able to generate a Entity Framework Model over the basic schema I've created. I have an event that adds data that I've been using to test these databases. Well, I kept adding a new record using EF and finding it didn't actually insert a record. In debugging, I checked the context object to see what was happening. It turns out that it is saying "the underlying provider failed to open," or something to that effect. It was not throwing an exception, just not inserting a record. The same thing has happened for all 3 embedded databases--prompting me to get it through my dense head that there has to be something wrong with my configuration. Well, I tried to write some basic sql using a sqlconnection and sqlcommand. This time it throws an exception. In the SQL Server Compact case, it now says: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) I thought perhaps a problem was the path in app.Config. So I changed the connection string to: Note that I simplified the path away from anything that might have spaces and avoided using the Data Directory nonsense that causes problem when the debugging directory does not match the preconfigured value for the data directory. I'm running Windows 7; I thought perhaps it might be an access issue--so I tried running VS 2010 in Administrator mode. No luck. I also installed Sql Server Compact SP2, thinking this might be a bug. No luck. Anyway, I'm ready to pull my hair out. I'm on a tight deadline for this thing and didn't expect to spend the day trying to figure out what is going on.

  • filesystem compatible with freenas and windows

    - by Daniel
    Hi all, I'm planning on using FreeNAS (was considering openfiler but freenas seems simpler) for my home NAS box running off ESXI. I have managed to get local sata drives to mount in ESXI (http://serverfault.com/questions/216902/esxi-add-datastore-without-partitioning). I've had one of the drives fail on my before and I was able to retrieve most of the data off it using windows tools (I'm not much of a linux guy I know enough to be dangerous!). If I go the freenas route in the event that something goes bad what would be the best file system to use so that I could pop the drive out of the freenas box (vm) and put it in another pc running windows so I could try and run various recovery tools to get the data back. All in all its not a major problem if I lose the data just would be a bit annoying, so I'm not looking for suggestions around backing up etc. I was considering using NTFS that the drives are already formatted as but it appears that while freenas does support NTFS that its a bit buggy and not 100% reliable, anyone know if this is still true? Read that on a forum somewhere.

  • Cannot change PostgreSQL port

    - by Jerec TheSith
    I run Postgresql 8.4 as a service on a CentOS 6.2 server. I set port = 21444 and listen_addresses = '*' in /var/lib/pgsql/data/postgresql.conf and I changed 5432 to 21444 in postmaster.opts and restarted postgres, but when I run netstat -lntp postgresql is still running on port 5432 tcp 0 0 0.0.0.0:5432 0.0.0.0:* LISTEN 20276/postmaster When I restart postgresql I get a writting error warning on /proc/self/oom_adj, but the service starts anyway. I read that we could get this error when using virtualized servers, but I don't really know if this has inpact on postgresql listening port. The correct pgsql config file is loaded in /var/lib/pgsql/data : [root@srv02 ~]# ps -ef | grep postgres root 1358 22140 0 09:42 pts/0 00:00:00 grep postgres postgres 9519 1 0 Mar16 ? 00:00:01 /usr/bin/postmaster -p 5432 -D /var/lib/pgsql/data postgres 9573 9519 0 Mar16 ? 00:00:00 postgres: logger process postgres 9575 9519 0 Mar16 ? 00:00:05 postgres: writer process postgres 9576 9519 0 Mar16 ? 00:00:03 postgres: wal writer process postgres 9577 9519 0 Mar16 ? 00:00:01 postgres: autovacuum launcher process postgres 9578 9519 0 Mar16 ? 00:00:01 postgres: stats collector process any thought ? thanks, Jerec

  • What is the fastest way to scale and display an image in Python?

    - by Knut Eldhuset
    I am required to display a two dimensional numpy.array of int16 at 20fps or so. Using Matplotlib's imshow chokes on anything above 10fps. There obviously are some issues with scaling and interpolation. I should add that the dimensions of the array are not known, but will probably be around thirty by four hundred. These are data from a sensor that are supposed to have a real-time display, so the data has to be re-sampled on the fly.

  • Ideas for multiplatform encrypted java mobile storage system

    - by Fernando Miguélez
    Objective I am currently designing the API for a multiplatform storage system that would offer same interface and capabilities accross following supported mobile Java Platforms: J2ME. Minimum configuration/profile CLDC 1.1/MIDP 2.0 with support for some necessary JSRs (JSR-75 for file storage). Android. No minimum platform version decided yet, but rather likely could be API level 7. Blackberry. It would use the same base source of J2ME but taking advantage of some advaced capabilities of the platform. No minimum configuration decided yet (maybe 4.6 because of 64 KB limitation for RMS on 4.5). Basically the API would sport three kind of stores: Files. These would allow standard directory/file manipulation (read/write through streams, create, mkdir, etc.). Preferences. It is a special store that handles properties accessed through keys (Similar to plain old java properties file but supporting some improvements such as different value data types such as SharedPreferences on Android platform) Local Message Queues. This store would offer basic message queue functionality. Considerations Inspired on JSR-75, all types of stores would be accessed in an uniform way by means of an URL following RFC 1738 conventions, but with custom defined prefixes (i.e. "file://" for files, "prefs://" for preferences or "queue://" for message queues). The address would refer to a virtual location that would be mapped to a physical storage object by each mobile platform implementation. Only files would allow hierarchical storage (folders) and access to external extorage memory cards (by means of a unit name, the same way as in JSR-75, but that would not change regardless of underlying platform). The other types would only support flat storage. The system should also support a secure version of all basic types. The user would indicate it by prefixing "s" to the URL (i.e. "sfile://" instead of "file://"). The API would only require one PIN (introduced only once) to access any kind of secure object types. Implementation issues For the implementation of both plaintext and encrypted stores, I would use the functionality available on the underlying platforms: Files. These are available on all platforms (J2ME only with JSR-75, but it is mandatory for our needs). The abstract File to actual File mapping is straight except for addressing issues. RMS. This type of store available on J2ME (and Blackberry) platforms is convenient for Preferences and maybe Message Queues (though depending on performance or size requirements these could be implemented by means of normal files). SharedPreferences. This type of storage, only available on Android, would match Preferences needs. SQLite databases. This could be used for message queues on Android (and maybe Blackberry). When it comes to encryption some requirements should be met: To ease the implementation it will be carried out on read/write operations basis on streams (for files), RMS Records, SharedPreferences key-value pairs, SQLite database columns. Every underlying storage object should use the same encryption key. Handling of encrypted stores should be the same as the unencrypted counterpart. The only difference (from the user point of view) accessing an encrypted store would be the addressing. The user PIN provides access to any secure storage object, but the change of it would not require to decrypt/re-encrypt all the encrypted data. Cryptographic capabilities of underlying platform should be used whenever it is possible, so we would use: J2ME: SATSA-CRYPTO if it is available (not mandatory) or lightweight BoncyCastle cryptographic framework for J2ME. Blackberry: RIM Cryptographic API or BouncyCastle Android: JCE with integraced cryptographic provider (BouncyCastle?) Doubts Having reached this point I was struck by some doubts about what solution would be more convenient, taking into account the limitation of the plataforms. These are some of my doubts: Encryption Algorithm for data. Would AES-128 be strong and fast enough? What alternatives for such scenario would you suggest? Encryption Mode. I have read about the weakness of ECB encryption versus CBC, but in this case the first would have the advantage of random access to blocks, which is interesting for seek functionality on files. What type of encryption mode would you choose instead? Is stream encryption suitable for this case? Key generation. There could be one key generated for each storage object (file, RMS RecordStore, etc.) or just use one for all the objects of the same type. The first seems "safer", though it would require some extra space on device. In your opinion what would the trade-offs of each? Key storage. For this case using a standard JKS (or PKCS#12) KeyStore file could be suited to store encryption keys, but I could also define a smaller structure (encryption-transformation / key data / checksum) that could be attached to each storage store (i.e. using addition files with the same name and special extension for plain files or embedded inside other types of objects such as RMS Record Stores). What approach would you prefer? And when it comes to using a standard KeyStore with multiple-key generation (given this is your preference), would it be better to use a record-store per storage object or just a global KeyStore keeping all keys (i.e. using the URL identifier of abstract storage object as alias)? Master key. The use of a master key seems obvious. This key should be protected by user PIN (introduced only once) and would allow access to the rest of encryption keys (they would be encrypted by means of this master key). Changing the PIN would only require to reencrypt this key and not all the encrypted data. Where would you keep it taking into account that if this got lost all data would be no further accesible? What further considerations should I take into account? Platform cryptography support. Do SATSA-CRYPTO-enabled J2ME phones really take advantage of some dedicated hardware acceleration (or other advantage I have not foreseen) and would this approach be prefered (whenever possible) over just BouncyCastle implementation? For the same reason is RIM Cryptographic API worth the license cost over BouncyCastle? Any comments, critics, further considerations or different approaches are welcome.

  • Hibernate CRUD à la Ruby on Rails' Scaffolding

    - by schonarth
    Guys, Do you know of any tool that would do like Ruby on Rails' Scaffolding (create simple CRUD pages for any particular class to allow quickly populating a database with dummy data), only which used Java classes with Hibernate for database access, and JSP/JSF for the pages? It is a drag when you are programming one part of an application, but need data that can only be added with another part that is not ready yet, or very cumbersomely by directly inserting it into the DB.

  • Which is the fastest way to move 1Petabyte from one storage to a new one?

    - by marc.riera
    First of all, thanks for reading, and sorry for asking something related to my job. I understand that this is something that I should solve by myself but as you will see its something a bit difficult. A small description: Now Storage = 1PB using DDN S2A9900 storage for the OSTs, 4 OSS , 10 GigE network. (lustre 1.6) 100 compute nodes with 2x Infiniband 1 infiniband switch with 36 ports After Storage = Previous storage + another 1PB using DDN S2A 990 or LSI E5400 (still to decide) (lustre 2.0) 8 OSS , 10GigE network 100 compute nodes with 2x Infiniband Previous experience: transfered 120 TB in less than 3 days using following command: tar -C /old --record-size 2048 -b 2048 -cf - dir | tar -C /new --record-size 2048 -b 2048 -xvf - 2>&1 | tee /tmp/dir.log So , big problem here, using big mathematical equations I conclude that we are going to need 1 month to transfer the data from one side to the new one. During this time the researchers will need to step back, and I'm personally not happy with this. I'm telling you that we have infiniband connections because I think that may be there is a chance to use it to transfer the data using 18 compute nodes (18 * 2 IB = 36 ports) to transfer the data from one storage to the other. I'm trying to figure out if the IB switch will handle all the traffic but in case it just burn up will go faster than using 10GigE. Also, having lustre 1.6 and 2.0 agents on same server works quite well, with this there is no need to go by 1.8 to upgrade the metadata servers with two steps. Any ideas? Many thanks Note 1: Zoredache, we can divide it in two blocks (A)600Tb and (B)400Tb. The idea is to move (A) to new storage which is lustre2.0 formated, then format where (A) was with lustre2.0 and move (B) to this lustre2.0 block and extend with the space where (B) was. This way we will end with (A) and (B) on separate filesystems, with 1PB each.

  • Help with iphone dev - beyond bounds error

    - by dusk
    I'm just learning iphone development, so please forgive me for what is probably a beginner error. I've searched around and haven't found anything specific to my problem, so hopefully it is an easy fix. The book has examples of building a table from data hard coded via an array. Unfortunately it never really tells you how to get data from a URL, so I've had to look that up and that is where my problems show up. When I debug in xcode, it seems like the count is correct, so I don't understand why it is going out of bounds? This is the error message: 2010-05-03 12:50:42.705 Simple Table[3310:20b] *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSCFArray objectAtIndex:]: index (1) beyond bounds (0)' My URL returns the following string: first,second,third,fourth And here is the iphone code with the book's working example commented out #import "Simple_TableViewController.h" @implementation Simple_TableViewController @synthesize listData; - (void)viewDidLoad { /* //working code from book NSArray *array = [[NSArray alloc] initWithObjects:@"Sleepy", @"Sneezy", @"Bashful", @"Bashful", @"Happy", @"Doc", @"Grumpy", @"Thorin", @"Dorin", @"Norin", @"Ori", @"Balin", @"Dwalin", @"Fili", @"Kili", @"Oin", @"Gloin", @"Bifur", @"Bofur", @"Bombur", nil]; self.listData = array; [array release]; */ //code from interwebz that crashes NSString *urlstr = [[NSString alloc] initWithFormat:@"http://www.mysite.com/folder/iphone-test.php"]; NSURL *url = [[NSURL alloc] initWithString:urlstr]; NSString *ans = [NSString stringWithContentsOfURL:url]; NSArray *listItems = [ans componentsSeparatedByString:@","]; self.listData = listItems; [urlstr release]; [url release]; [ans release]; [listItems release]; [super viewDidLoad]; } - (void)didReceiveMemoryWarning { // Releases the view if it doesn't have a superview.
