Using tar+lz4/pigz+faster data transfer with SSH -- One-8|Ten: 41 Category: Linux,mysql |The previous article describes how to maximize the transfer speed of the SCP, with this foundation, you can further use compression to speed up the transmission. Using only SCP, the fastest transfer rate is about 90MB, this article will increase the fastest transfer rate to about 250MB by compressing/s (including the decompression process). directory [hide]1.

? ? ? ? ? ? ? ?When people try to learn JavaScript or other programming languages, they often encounter the following challenges.
Some concepts confuse them, especially if they have learned other types of language before.
It's hard to find the time (or motivation) to study.
It's easy to forget what you learned before.
JavaScript tools are too many and often updated to make it difficult to find a starting point for learning.
Fortunately, these problems can eventually be

On Weibo today, I was told that I-is faster than I ++.ProgramAfter testing, it was really fast. Isn't subtraction faster than addition? It seems impossible to analyze the principle, So I studied it in depth and finally found the cause.
Take a look at the testCode:
# Include IntMain (){IntCount = 1000000000; clock_t Cl = clock ();For(IntI = count; I> 0; I --) {} printf ("Elapse % u Ms \ r \ n", (Clock ()
An xmemcpy tool is used for memory copying. It is said that the memcpy provided by glibc is 10 times faster than the memcpy provided by glibc when the data is copied within 120 bytes, And there is experimental data.
This is quite surprising. Memcpy has always been very efficient. Compared with the byte copy of functions such as strcpy, memcpy copies data word by word based on the machine Name Length. A word is 4 (32-bit) or 8 (64-bit) bytes. CPU acc
Visual Studio. NET is "devenv ".
Of course, there are some program programs that are easy to find under system32. the extension name of the example is not .exe, such as control (control panel), gpedit. MSC (Group Policy), msconfig (system configuration), etc. Some "hide" commands, such as control userpasswords2.
In Windows XP and earlier Windows operating systems, this key is my favorite. Because many programs are installed on my computer, it is very time-consuming to start from "start-program.

Although recent depth object detection methods such as: Fast/faster RCNN in general object detection, show a strong performance, but for pedestrian detection is no

Tells you some simple tricks to optimize the javascript compiler to work, so your JavaScript code runs faster. Especially when you find that the frame rate drops in your game or when the garbage collector has a lot of work to do.Single State:When you define a function with two parameters, the compiler will accept your definition, and it will be difficult to change the compiler 's work if the type, number, or type of return value of the function parame
Download and install software under Ubuntu using different image sources The speed difference is very large, the official one is relatively slow, so choose the fastest most efficient. Setup method is different, the online tutorial is more common is to manually change the update source list, the specific version of the source list is copied directly into the/etc/apt/sources.list file, but sometimes the source file will be invalidated, and not necessarily each time the source files are compatible

Lightroom is a very convenient and powerful tool, but speed is not very ideal for many people, how can it be faster? In addition to improving the hardware, from the photographer Andrew S. Gibson, the following steps and techniques can effectively improve the speed of using LR repair.
Focus: Turn RAW files into DNG format, and "Inline Quick load data" (fast load data) and create a 1:1 preview so that you can use a higher speed when zooming
meaning of the array, but familiar with JS know, it is actually a non-linear pseudo array, subscript can be any number. Write arr[1000000] does not really request space to hold 1 million elements, but instead converts 1000000 to a corresponding hash value, which corresponds to a small piece of storage space, thus saving a lot of memory.
For example, there are the following arrays:
Copy Code code as follows:
var arr = [];
ARR[10] = 1000;
ARR[20] = 2000;
ARR[30] = 5000;
Web page Production WEBJX article introduction: write CSS that is lighter, faster, and less likely to give you headaches.
Why is our CSS so messed up-we're really easy to get caught up in this confusion.
Sometimes this is the result of sloppy programming at first, sometimes because of late multiple additional code (hacks) and modifications.
Either way, it's not inevitable. Write clean, super manageable CSS is simple, as long as you go the
reduce the 0.5 seconds repeat time and and/or you can see if you can reduce the intermediate result SE TS (which is usually what get cached and speed up the the queries the second. Nth runs). If the query is producing a large intermediate result set (perhaps a large join where most records be then discarded), yo U May is able to speed it up by changing parts of your query. Also, sometimes just adding the right index can solve issues like this. Look at the execution plan and see if there is any

Dive into Python says that a tuple is an immutable list, and once a tuple is created, it cannot be changed in any way. But a Tuple operates faster than a list. If you define a constant set of values and the only thing you want to do with it is to iterate over it, use tuple instead of list. I wrote a few lines of code to test it:Example_list=list () for I in Range (0,500,1): example_list.append (i) example_tuple=tuple (example_list) start= Time.cloc
