Heap Memory In C

I have been unable to tolerate the slow pace of progress in programming learning, but I am always very inefficient learning, so from now on, in this series of blogs, accumulated record in the process of programming experience and reflection, hoping to really let themselves grow up quickly. Make up your mind, be patient, focus on the present, and be firm in your fear. The best way to learn other people's code is to step into the program to debug, understand the general framework and process, and then delve into the C language strlen () trap strlen () the role is to take ...

Although the "editor's note" has been available for 9 years, the popularity of Mongodb,hamsterdb is still lacking, and it has been rated as a Non-mainstream database. Hamsterdb is an open source key value type database. However, unlike other Nosql,hamsterdb, which are single-threaded and not distributed, they are designed to be more like a column store database, while also supporting acid transactions at the Read-committed isolation level. Then compare Leveldb,hamsterdb will have any advantage, here we go ...

Hello everyone, I am from Silicon Valley Dong Fei, at the invitation of domestic friends, very happy to communicate with you about the U.S. Big Data Engineers interview strategy. Personal introduction to do a self-introduction, after the undergraduate Nankai, joined a start-up company Kuxun, do real-time information retrieval, and then enter the Baidu Infrastructure group, built the Baidu APP engine earlier version, and then went to Duke University, in the study, during the master's degree, Starfish, a research project related to Hadoop's big data, and then Amazon ...

First of all: Hadoop is disk-level computing, when computing, data on disk, need to read and write disk; http://www.aliyun.com/zixun/aggregation/13431.html ">storm is a memory-level calculation, Data imports memory directly over the network. Read/write memory is faster n order of magnitude than read-write disk. According to the Harvard CS61 Courseware, disk access latency is about 75,000 times times the latency of memory access. 　　So storm faster. ...

Last year in the investigation of a lot of java applications, see some of the phenomenon is the programmer to run on their own environment to read the program rarely lead to troubleshooting problems will be more frustrating, so think of writing this series of articles, procedures To provide functionality to end-users, the code is only one part of it, and it needs to be relied on for jvm, os, server hardware, networking, load balancing, etc. In this series of articles, Several parts, more is only a science role, because os I use are linux, this series ...

Some days ago, an old colleague came to talk to me about the design of the homepage of the channel, which reminds me that I used to do the media, before I painted a lot of content page prototype.
