  • What does this IIS error log mean?

    - by Victor Rodrigues
    I'm using Debug Diagnostic Tool, trying to understand why around 5% of the requests that are sent to my webservice just crash, without necessarily throw any error inside my application. One of the errors this tool took is below. Can anyone here understand exactly what could be happening? Thanks!

  • How to get compatibility between C# and SQL2k8 AES Encryption?

    - by Victor Rodrigues
    I have an AES encryption being made on two columns: one of these columns is stored at a SQL Server 2000 database; the other is stored at a SQL Server 2008 database. As the first column's database (2000) doesn't have native functionality for encryption / decryption, we've decided to do the cryptography logic at application level, with .NET classes, for both. But as the second column's database (2008) allow this kind of functionality, we'd like to make the data migration using the database functions to be faster, since the data migration in SQL 2k is much smaller than this second and it will last more than 50 hours because of being made at application level. My problem started at this point: using the same key, I didn't achieve the same result when encrypting a value, neither the same result size. Below we have the full logic in both sides.. Of course I'm not showing the key, but everything else is the same: private byte[] RijndaelEncrypt(byte[] clearData, byte[] Key) { var memoryStream = new MemoryStream(); Rijndael algorithm = Rijndael.Create(); algorithm.Key = Key; algorithm.IV = InitializationVector; var criptoStream = new CryptoStream(memoryStream, algorithm.CreateEncryptor(), CryptoStreamMode.Write); criptoStream.Write(clearData, 0, clearData.Length); criptoStream.Close(); byte[] encryptedData = memoryStream.ToArray(); return encryptedData; } private byte[] RijndaelDecrypt(byte[] cipherData, byte[] Key) { var memoryStream = new MemoryStream(); Rijndael algorithm = Rijndael.Create(); algorithm.Key = Key; algorithm.IV = InitializationVector; var criptoStream = new CryptoStream(memoryStream, algorithm.CreateDecryptor(), CryptoStreamMode.Write); criptoStream.Write(cipherData, 0, cipherData.Length); criptoStream.Close(); byte[] decryptedData = memoryStream.ToArray(); return decryptedData; } This is the SQL Code sample: open symmetric key columnKey decryption by password = N'{pwd!!i_ll_not_show_it_here}' declare @enc varchar(max) set @enc = dbo.VarBinarytoBase64(EncryptByKey(Key_GUID('columnKey'), 'blablabla')) select LEN(@enc), @enc This varbinaryToBase64 is a tested sql function we use to convert varbinary to the same format we use to store strings in the .net application. The result in C# is: eg0wgTeR3noWYgvdmpzTKijkdtTsdvnvKzh+uhyN3Lo= The same result in SQL2k8 is: AI0zI7D77EmqgTQrdgMBHAEAAACyACXb+P3HvctA0yBduAuwPS4Ah3AB4Dbdj2KBGC1Dk4b8GEbtXs5fINzvusp8FRBknF15Br2xI1CqP0Qb/M4w I just didn't get yet what I'm doing wrong. Do you have any ideas? EDIT: One point I think is crucial: I have one Initialization Vector at my C# code, 16 bytes. This IV is not set at SQL symmetric key, could I do this? But even not filling the IV in C#, I get very different results, both in content and length.

  • How to use a data type (table) defined in another database in SQL2k8?

    - by Victor Rodrigues
    I have a Table Type defined in a database. It is used as a table-valued parameter in a stored procedure. I would like to call this procedure from another database, and in order to pass the parameter, I need to reference this defined type. But when I do DECLARE @table dbOtherDatabase.dbo.TypeName , it tells me that The type name 'dbOtherDatabase.dbo.TypeName' contains more than the maximum number of prefixes. The maximum is 1. How could I reference this table type?

  • NSFetchedResultsController not processing certain section driven moves

    - by JK
    I utilize a NSFetchedResultsController (frc) with a Core Data store. I implement all the frc delegate methods. The table is sporadically updated by background threads. All the inserts, deletes and updates work fine, with the exception that updates to the frc's index key for rows toward to the bottom of the table (50 rows), do not result in a section move. e.g. if "name" is the index key and the name "Victor" is changed to "Alex", the victor row now shows the name Alex, but is not moved to the top of the table alongside all other names starting with A. As I noted, this is only for rows towards the bottom of the table. If a row like "Andy" is changed to "Ben", the move is indeed processed correctly by the frc. Any suggestions to fix this would be appreciated. I do not use a frc cache. Thanks

  • Create a unique ID by fuzzy matching of names (via agrep using R)

    Using R, I am trying match on people's names in a dataset structured by year and city. Due to some spelling mistakes, exact matching is not possible, so I am trying to use agrep() to fuzzy match names. A sample chunk of the dataset is structured as follows: df <- data.frame(matrix( c("1200013","1200013","1200013","1200013","1200013","1200013","1200013","1200013", "1996","1996","1996","1996","2000","2000","2004","2004","AGUSTINHO FORTUNATO FILHO","ANTONIO PEREIRA NETO","FERNANDO JOSE DA COSTA","PAULO CEZAR FERREIRA DE ARAUJO","PAULO CESAR FERREIRA DE ARAUJO","SEBASTIAO BOCALOM RODRIGUES","JOAO DE ALMEIDA","PAULO CESAR FERREIRA DE ARAUJO"), ncol=3,dimnames=list(seq(1:8),c("citycode","year","candidate")) )) The neat version: citycode year candidate 1 1200013 1996 AGUSTINHO FORTUNATO FILHO 2 1200013 1996 ANTONIO PEREIRA NETO 3 1200013 1996 FERNANDO JOSE DA COSTA 4 1200013 1996 PAULO CEZAR FERREIRA DE ARAUJO 5 1200013 2000 PAULO CESAR FERREIRA DE ARAUJO 6 1200013 2000 SEBASTIAO BOCALOM RODRIGUES 7 1200013 2004 JOAO DE ALMEIDA 8 1200013 2004 PAULO CESAR FERREIRA DE ARAUJO I'd like to check in each city separately, whether there are candidates appearing in several years. E.g. in the example, PAULO CEZAR FERREIRA DE ARAUJO PAULO CESAR FERREIRA DE ARAUJO appears twice (with a spelling mistake). Each candidate across the entire data set should be assigned a unique numeric candidate ID. The dataset is fairly large (5500 cities, approx. 100K entries) so a somewhat efficient coding would be helpful. Any suggestions as to how to implement this?

  • Exclude specific domains from Apache2 serverAlias while using a catch all *(wildcard) alias

    - by Victor S
    I have a web application that needs to support custom domains, in that regard I have set-up the following name based virtual server: <VirtualHost *:80> ServerName example.com ServerAlias * *.example.com www.example.com example.com RailsEnv production RackEnv production DocumentRoot /srv/www/example/current/public <Directory /srv/www/example/current/public> AllowOverride all Options -MultiViews FollowSymLinks </Directory> ErrorLog /srv/www/example/log/error.log TransferLog /srv/www/example/log/access.log </VirtualHost> Notice the * as the server alias? that catches all the domains on that server. However, I have other sites on this server which I want to be excluded from this list. It is more economical for me to have a list of excluded domains than manually set every domain a user may register with at this service as a serverAlias... Perhaps this is not the best way to go, but I'm looking for help, in the best (relatively simple) way to set up a web-app that may catch any domains, while allowing other specific domains to be routed to different apps. Thanks!

  • How to check for the existence of a response header in Nginx rules?

    - by Victor Welling
    Setting up the rewriting rules for the request proved to be quite easy in Nginx. For the response, not so much (at least, not for me). I want to strip the Content-Type header from the response if the Content-Length header of the response isn't set. I have the NginxHttpHeadersMoreModule installed, so that should allow me to remove the header, but I can't seem to find a way to check for the existence of the Content-Length header of the response using a rule in Nginx's configuration. Any suggestions on how to do this would be most appreciated!

  • Selective Disable APC caching

    - by Victor
    I installed APC on my VPS and it works great with W3 Cache wordpress plugin. My problem is that there is one database in MySQL which is pinged by client end every few seconds to see if there are new updates. These db contains certain time sensitive information and hence it can't be part of cached data. How can I disable APC for this database/files? or Can I set a very short expiry of certain type of data? Any help is highly appreciated.

  • Apache maximum request number 256?

    I have a very good server running an Apache instance with mod_jk for proxying the request to an Application server. I'm doing a load test and although I'm sending over 600 requests, the status worker keep showing this: 256 requests currently being processed, 0 idle workers I'm using 'prefork MPM' <IfModule prefork.c> ServerLimit 2048 StartServers 5 MinSpareServers 5 MaxSpareServers 10 MaxClients 1000 MaxRequestsPerChild 0 </IfModule> Is there a compiled limit for Apache to handle just 256 request or what would I be missing?

  • Setting default working directory/drive in Emacs shell on Windows

    - by Victor K.
    Hello, how can I change a default working directory/drive for shell in Emacs (on Windows)? Normally, shell starts in the same directory as the file in current buffer. However, when my current file is on D: drive, it starts in c:. Manually changing drive to D: in shell brings me to my directory of course, but I want to avoid this extra step. Is it possible?

  • WinXP keyboard input repeat rate problem

    - by Victor Sorokin
    I have problem similar to http://superuser.com/questions/33981/problems-with-kvm-switch-and-keyboard-repeat-rate-on-windows-xp: When I press and hold some key it's repeated random number of times, after that repeat stops and I need to release key and press it again to make repeat continue. If there's simultaneous sound playback and repeat is stopped, sound's stuck while I hold key with unpleasant drumming as if there's some audio problem. This issue is reproducible in WinXP Safe Mode. On the same config under Linux there's no issue. My config: List item PS/2 Logitech Keyboard USB Mouse MB M3A/H-HDMI WinXP Pro English SP2 with added Russian layout (WinXP loads via GRUB2) Realtek audio drivers for AC97 Thanks for your suggestions J
