It is possible that a miscarriage of judgment will not false negative first, what is Bloom FilterBloom Filter is a random data structure with high spatial efficiency, which is the principle that when an element is added to a set, the element is mapped to a K-point in a bit array by a K-hash function , set them to 1. When retrieving, we just have to look at whether these points are all 1 (about) know if there are any of them in the collection: If these points have any one 0, then the retrieved

There can several points specializing in the same pair of currencies. Each point has its own exchange rates, and exchange rate of A to B is the quantity of B you get for 1A. Also each of the exchange point has some commission, the sum of which has a to pay for your

for indie game developers. Many developers choose Chartboost, because the latter allows the game to reach high-quality players, and the costs are acceptable.ECPA refers to the cost of effective user acquisition, that is, the total cost of acquiring each player, plus the amount of downloads that the player is attracted to. In a way, ECPA can also be used to measure the viral spread potential of your network. ECPA is always smaller than CPA, because it has an additional effect, but its biggest di
Occasionally saw Ali middleware Dubbo performance test Report, I think this performance test report to people do not understand the performance test performance testing, I think this report will bring the public ditch, so, want to write this article, do a little science.First, the main problems in this test report are as follows:1) are all averages. To be honest, the average is very unreliable.2) The response time is not pegged to the throughput tps/qps. It is completely wrong to just test the l
Website Bounce Rate (Bounce rates) is an important index to evaluate the performance of a website, high bounce rate, indicating that the user experience of the site is not good, the user jumped out, on the contrary if the rate is lower, the user experience of the site is good, users can find their own needs of the content. And later he may come back to visit your website, improve the user stickiness.Slowly can accumulate a large number of website user
support these two rates and can convert the two rates between frames;This system can also compress and decompress music and other audio signals, but it is optimal for voice signals. It adopts the mute compression for discontinuous transmission, this means that artificial noise is added to the bit stream during mute. In addition to reserved bandwidth, this technology keeps the sender's modem working continu

Arbitrage
DescriptionArbitrage is the use of discrepancies in currency exchange rates to transform one unit of a currency into more than one unit of the same currency. for example, suppose that 1 US dollar buys 0.5 British pound, 1 British pound buys 10.0 French francs, and 1 French franc buys 0.21 US dollar. then, by converting currencies, a clever trader can start with 1 US dollar and buy 0.5*10.0*0.21 = 1.05 US dollars, making a profit of 5 percent
continuously pass through the human eye. In this regard, animals are much faster than humans. For example, predators in birds can capture more information. Therefore, even at the 80Hz update rate, they will notice the flash. The human eye cannot see these obvious flashes at a frequency above 60Hz, but as we described in the FPS chapter, after testing, the human eye can detect one frame of 200 frames in a second. So even if you don't notice a significant flash at a low update rate, subconsciousl
G.723.1 specifies a coded representation that can be used for compressing the speech or other audio signal component of multimedia services at a very low bit rate. in the design of this coder, the principal application considered was very low bit rate Visual Telephony as part of the overall H.324 family of standards.
G.723.1 has two bit rates associated with it. these are 5.3 and 6.3 kbit/s. the higher bit rate has greater quality. the lower bit rate
States, the MTBF of the software should be between 1000 hours and 10000 hours, which should be an advanced indicator.Currently, the most important indicator of software reliability is MTBF. Other indicators need to be further explored, such as the hardwareMTTR (average service time) indicators. However, for software, users should not modify the software on their own.Software modifications are likely to get worse and worse. Under normal circumstances, the software must be modified by the origina
lossless because the human ear cannot distinguish between a CD recording and a properly encoded MP3 version of it. MP3s achieve this transparency at a bit rate of approximately 256 kilobits per second, or roughly one sixth of the 1.4 megabits per second required by the compact disc format.
MP3s can be recorded at lower bit rates, saving even more space, but audible differences begin to appear at rates
) applications. file-based compression is of course also supported. voice conversation codec requires a free open-source software, so it was born speex library, which can be used in any open-source software. Actually, speex for voice dialogs, it is equivalent to Vorbis [ A coding software that compresses sound sources, open source and copyright-free ] for audio / music. Unlike most speech codec libraries, speex not designed for mobile phones, VoIP (Voice over IP) apply
