Is there any way to convert differential backup to SQL statements which will produce identical results when applied?
Or any other solution similar to binary log in MySQL?
I have an ASP.NET website and I want to find the /bin/[Configuration] folder to use an external tool. When I use reflection to get calling assemblies location it returns something similar to:
C:\Windows\Microsoft.NET\Framework\...\Temporary ASP.NET Files\a1388a5e\...\my.dll
Since each dll has its own directory under the temp ASP.NET Files this fails for me.
How can I get the location of the binary, not asp.net's temporary cache?
Hi,
I am trying to learn C++ maps. Was just wondering about the implementation of STL map. I read it employs Binary search tree.
Is there a implementation of hash table in STL?
How exactly do STL map stores Key Value pairs?
I'm working with a binary file that I disas'd in gdb. Right now I'm just examining the return value of a function.
0x08048604 <playGame+78>: ret
Is the address shown the address where ret is stored in the function? Or is it just the address of the instruction to return the ret value?
I am writing web application using ASP.NET MVC + NHibernate + Postres stack. I wonder if images uploaded should be stored in database as binary blobs or on filesystem (and reference only in db).
One advantage of db storage I can think of is easy backup/recovery of all data without reverting to filesystem copy tools. On the other hand I suspect that filesystem access may be faster (but is it especially when dealing with many concurrent requests?)
What are your suggestions?
I'm currently profiling an implementation of binary search. Using some special instructions to measure this I noticed that the code has about a 20% misprediction rate. I'm curious if there is any way to check how many cycles I'm potentially losing due to this. It's a MIPS based architecture.
Is it really possible, with Google's V8 Engine, to compile JavaScript into Native Code, save it as a binary file, and execute it whenever I want through my software envorinment, on any machine?
Hi all,
Assume I have a class
class A
{
char *attr1,*attr2;
public:
. . .
};
How to save the object of this class to file in a binary format and read it back?
Thanks.
I'm currently using statement-based replication. After upgrading to MySql 5.1, I'm considering using row-based replication.
After reading the docs it seems that you can change the format of the master on the fly.
Will the slave automatically adapt to whatever type of binary log it is sent?
Do I have to make any changes to the slave or master to get ready for switching or can I simply modify the binlog_format variable on the master?
a bit of a binary question (okay, not excatly) - but was wondering if one is able to configure cloudera / hadoop to run at the nodes without root shell access to the node computers (although i can setup ssh passwordless login)?
appears from their instructions that root access is needed, at yet i found a hadoop wiki which suggest root access might not be needed ? http://wiki.apache.org/nutch/NutchHadoopTutorial
And, does it cache it locally?
I ask because I am wondering if it's possible to change the sound of a push notification via SSH, replacing an app sound.
My question is specifically about how the API for push notifications works. Does it send a .caf (aiff) binary file for the phone to play each time?
Hi, I wanted to use this code to send archives with Xmodem: http://www.java2s.com/Code/Java/Network-Protocol/JModemsimplecommunicationsprogram.htm
In this case, I want to establish a dialup connection between two computers and send a binary file. But this code doesn't let me set a phone number to dial after i setup the port and before I transfer the file. Is there any way of sharing the port with another application that dials the phone number?
Can I define in C++ an array operator that takes multiple arguments? I tried it like this:
const T& operator[](const int i, const int j, const int k) const{
return m_cells[k*m_resSqr+j*m_res+i];
}
T& operator[](const int i, const int j, const int k){
return m_cells[k*m_resSqr+j*m_res+i];
}
But I'm getting this error:
error C2804 binary operator '[' has too many parameters
I wrote a plugin system and I want to save/load their properties so that if the program is restarted they can continue working. I use binary serialization. The problem is they can be serialized but not deserialized.
During the deserialization "Unable to find assembly" exception is thrown. How can I restore serialized data?
hi,
I've to make a code to upload/download a file on remote machine. But when i upload the file new line is not saved as well as it automatically inserts some binary characters. Also I'm not able to save the file in its actual format, I've to save it as "filename.ser". I'm using serialization-deserialization concept of java.
Thanks in advance.
Looking at using either ObjectiveResource or ASIHTTPRequest ...
Which is superior for uploading images? Or is there a better option???
Are there any examples of using either or both to upload images (or any other binary content)?
Thanks
HI everyone,
during the various stages of compilation in C or C++, i know that an object file gets generated.
i.e., any_name.o file.
what does thos .o file contain actually.
i cant open it since its a binary file.
Could anybody please help me?
are the contents of the object file mainly Dependant on the compiler which we use on unix?
Hi all,
Boost serialization doc's assert that the way to serialize/deserialize items is using a binary/text archive with a stream on the underlying structure. This works fine if I wan't to use the serialized data as an std::string, but my intention is to convert it directly to a char* buffer. How can I achieve this without creating a temporary string?
Hi, i would like to create a Rails controller that download a serie of jpg files from the web and directly write them into database as binary
(I am not trying to do an upload form)
Any clue on the way to do that ?
Thank you
Edit :
Here is some code I already wrote using attachment-fu gem :
http = Net::HTTP.new('awebsite', 443)
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_NONE
http.start() { |http|
req = Net::HTTP::Get.new("image.jpg")
req.basic_auth login, password
response = http.request(req)
attachment = Attachment.new(:uploaded_data => response.body)
attachement.save
}
And I get an "undefined method `content_type' for #" error
Hi guys,
I just wanted to know if its necessary to set up all the banking info before proceeding with submission of the actual paid app for the binary.
Thanks and Regards,

Hi,
I want to show images that are requested from a binary field (blob) out of a mysql database. They are retrieved by a PHP script and outputs a 'real' jpeg image i.e. header('Content-Type') = 'image/jpeg'. This is working.
But how can i intercept this image that is being made by an ajax call ?
Im trying to download and save a file from a HttpWebResponse but im having problems saving the file (other than Text Files) properly.
I think its something to do with this part:
byte[] byteArray = Encoding.UTF8.GetBytes(http.Response.Content);
MemoryStream stream = new MemoryStream(byteArray);
Text Files work fine with the above code but when I try to save the Content to an Image file it gets corrupted.
How do i write this 'string' data to an image file (and other binary files)
I have a lot of #define's in my code. Now a weird problem has crept up.
I have this:
#define _ImmSign 010100
(I'm trying to simulate a binary number)
Obviously, I expect the number to become 10100. But when I use the number it has changed into 4160.
What is happening here? And how do I stop it?
