101. The C99 standard introduces the following datatypes. The documentation can be found here for the AVR stdint library. uint8_t means it's an 8-bit unsigned type. uint_fast8_t means it's the fastest unsigned int with at least 8 bits. uint_least8_t means it's an unsigned int with at least 8 bits. I understand uint8_t and what is uint_fast8_t ...
Note that the fast version could be larger than 32 bits. While the fast int will fit nicely in a register and be aligned and the like: but, it will use more memory. If you have large arrays of these your program will be slower due to more memory cache hits and bandwidth.
1 de mar. de 2012 · To fast-forwardand keep the local changes (rebase): git fetch && git checkout ${the_branch_name} && git rebase origin/${the_branch_name} * - to undo the change caused by an unintentional hard reset, first do git reflog. That displays the state of the HEAD in reverse order.
9 de dez. de 2013 · I am fairly new to git, yet currently using it to manage our code in a team environment. I had some rebasing issues, and I fixed them using: git checkout --ours filename.txt git add filename.txt git
The worst way is to send to Recycle Bin: you still need to delete them. Next worst is shift+delete with Windows Explorer: it wastes loads of time checking the contents before starting deleting anything. Next best is to use rmdir /s/q foldername from the command line. del /f/s/q foldername is good too, but it leaves behind the directory structure.
18 de out. de 2016 · The key checks for FAST REFRESH includes the following: 1) An Oracle materialized view log must be present for each base table. 2) The RowIDs of all the base tables must appear in the SELECT list of the MVIEW query definition. 3) If there are outer joins, unique constraints must be placed on the join columns of the inner table.
The point of UTF-8 is to be able to encode 21-bit characters (Unicode) as an 8-bit data stream (because that's the only thing all computers in the world can handle). But since most OSs predate the Unicode era, they don't have suitable tools to attach the encoding information to files on the hard disk. The next issue is the representation in Python.
Dim handle As GCHandle = GCHandle.Alloc(pixels, GCHandleType.Pinned) Dim addr As IntPtr = Marshal.UnsafeAddrOfPinnedArrayElement(pixels, 0) Dim bitmap As New Bitmap(imageWidth, imageHeight, stride \ 8, fmt, addr) What you have now is a simple Integer array and a Bitmap referencing the same memory.
19 de abr. de 2015 · then you will need to consider word size (8 bytes in a 64-bit system, 4 bytes in a 32-bit system) when allocating space for n pointers. The size of a pointer is the same of your word size. So while you may wish to allocate space for n pointers, you are actually going to need n times 8 or 4 (for 64-bit or 32-bit systems, respectively)
3 de out. de 2016 · For the fast path (neither branch taken) you could critical path reduce latency by using integer shifts on the XMM register, vpsrld xmm2, xmm0, 23 in parallel with vmovd eax, xmm0. (Subtracting the high bit of the mantissa from an exponent would take more shifts, might be more costly for throughput.)
