line, the short seller's profit chips have been cleared, there is no pressure in your hands to empty your chips. Many users hold coins to absorb them at a low level to form a demand. Those who are not sure about the cards are locked, and the chips cannot be locked easily. Therefore, the supply in this Price Range is less than the demand, which naturally forms a
representation of its memory chip capacity, which can be said to be one of the most formal forms.
Industry-standard memory chip capacity Representation
After calculation, we can find that the capacity of these three specifications is 128 Mbits, but the change in BIT width leads to a change in the number of storage units. From this example, we can also see that in the same total capacity, the bit width can adopt a variety of different designs.3. dimm design related to chip Bit WidthWhy is ther

Almost all current 3D display chips have Z buffer or W buffer. However, we can often see that someW buffer has some basic problems, such as the usage of Z buffer, Z buffer and W BufferOr accuracy issues. The purpose of this article is to briefly introduce Z buffer and W buffer.What is the use of Z buffer and W buffer? Their main purpose is to remove the hidden surface, that is, the hidden surface.Elimination (or find the visible surface detemination,

How to pick a solid state drive?
Open a large electric dealer website SSD Solid State hard disk Display page, currently can see 40 different brands. This may confuse many people, how can there be so many brands? To know, the mechanical hard disk market after the brutal competition baptism, currently left several famous brands: Seagate, Western Data (west), Toshiba, Hitachi, which Hitachi has also been acquired by the West. Mechanical hard disk manufacturing technology is very complex, harsh con
implemented on DDR3. This pin will make the initialization of the DDR3 easier. When the reset command is in effect, the DDR3 memory stops all operations and switches to the smallest active state to conserve power. During reset, DDR3 memory shuts down most of the intrinsic functions, so both the data receiver and the transmitter will be closed. All internal programs will be reset, DLL delay PLL and clock circuit will stop working, and ignore any movement on the data bus. This will enable DDR3 to
Beijing Time September 10 Noon news, according to foreign media reported today, AMD Global marketing vice President Leslie Soben (Leslie Sobon) in the media interview that AMD is ready to change marketing strategy, no longer compete with Intel performance.
Surrender in Disguise
Soben says users don't need to know the technical details of microprocessors, and what's more important for them is what the computer with the chip can handle. The new marketing strategy based on this idea is expected t

languages: Erlang and C
Features: compatible with Memcache, but with both persistence and cluster support

Protocol: distributed cache and Expansion
Very fast (200 k +/second), data is indexed by key value
Persistent storage to Hard Disk
All nodes are unique (master-master replication)
Cache Units similar to distributed cache are also supported in the memory.
When writing data, I/O is reduced by removing duplicated data.

Writes are much faster than reads (!)
MAP/reduce possible with Apache hadoop

The original version of cocos2d was written in Python and then changed to objectivec, which was applied to the iPhone. Then someone in China changed it to C ++ version cocos2dx based on the design concept, this version can run on three platforms: iPhone, Widnows, and andriod. the latest version is 1.0.0.The Lua script system is introduced. cocos2d is a fully open-source engine. developers can use this code without disclosing source code. cocos2d is widely used, including

I read a blog scaling a few days ago.Farmville talked about a concept of server design. Farmville was developed by Zynga, the famous social game operator. This game has created an amazing achievement of 7.5 million monthly active users. As a fellow player, I certainly need to pay attention to it.
From graduation to now as socialGame has been around for seven months. Let's talk about my experience first.
