问题 Amazon S3 interprets my binary data as non-UTF-8 and modifies it when I write to a bucket. Example using the official s3 Javascript client: var png_file = new Buffer( "iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==", "base64" ).toString( "binary" ); s3.putObject( { Bucket: bucket, Key: prefix + file, ContentType: "image/png;charset=utf-8", CacheControl: "public, max-age=31536000", Body: png_file // , ContentLength: png_file

问题 I am developing on a Windows machine for which I don't have administrative privileges. I would like to use CMake to compile, and I cannot simply download and install this due to administrative restrictions. I would also like to avoid compiling CMake from source (if possible). Are there portable binaries available for Windows that would allow one to simply use CMake? 回答1: You can download a ZIP file of CMake. You can just uncompress it somewhere you are allowed to copy files and use it from

问题 I'm messing with assembly language programming and I'm curious how I could tell if a number is a multiple of 4 using the logic operator AND? I know how to do it using "div" or "remainder" instructions but I'm trying to do this with bit manipulation of number/word. Can anyone point me in the right direction? I'm using MIPs but a Language agnostic answer is fine. 回答1: Well, to detect if a number is a multiple of another, you simply need to do x MOD y . If the result is 0 , then it is an even

问题 I have some base-64 encoded strings in SQL Server database, for example: DECLARE @x VARBINARY(64); SET @x = 0x4b78374c6a3733514f723444444d35793665362f6c513d3d When it's CAST or CONVERTED to a VARCHAR, I get: +˽Ð:¾Îréî¿• I'm looking for SQL Server to return a varchar with the hexadecimal representation of the varbinary as a varchar, e.g.: 4b78374c6a3733514f723444444d35793665362f6c513d3d Is there a build in CAST/CONVERT/function that does this, or does it have to be added as a User Defined

问题 I have some sets of combinations and I want to find out the intersection function between say two of them. Then I want to represent the intersected results in ZDD. I am thinking about using the CUDD package to do this. An example: All the 4-bit strings having hamming distance >= 2 with 1100 = { 0001, 0010, 0011,0101, 0110, 0111, 1001, 1010, 1011 } All the 4-bit strings having hamming distance >= 2 with 0000 = { 0011, 0101, 0110, 1001, 1010, 0111, 1011, 1101, 1110 } Intersected elements of the

问题 I need a binary search function. I couldn't find any function in the standard library that will return the index of the found item, and if it wasn't found, will return the bitwise complement of the index of the next element that is larger than the item I looked for. What is the function I am looking for? Edit: I need to insert an item to a sorted vector and to keep it sorted. That's why I need to bitwise complement index. 回答1: I'm quite certain the standard library doesn't include anything to

问题 I was given a task to convert decimal input numbers and output its binary equivalent via an "array" using assembly. I've the code complete and working, trouble is it only accepts numbers 0-99 for conversion. Ideally, the program should be able to convert any number at least up to 255 decimal so that the code can be reusable for future practices where I might need to handle different 16 bit values within registers. I appreciate all advice given, the code is as follows: .model small .stack
