string (10 ^ 7/8/1024/1024 ≈ 1 MB) and set each bit to 0;Read the file that contains a positive integer. For each I, set the bit [I] bit in the memory to 1.Reads strings in bits. Output (INT) J when bit [J] is 1. The pseudocode is as follows: for i= [0,n] bit[i]=0;for each i in the input file bit[i]=1;for i=[0,n] if bit[i] == 1 write i on the output file The core of bitmap is bit storage (becauseNo duplicate data, 1 bit is enough.) with a bit int ing of the int value, the prob

tornado development platform. VxWorks appears earlier, real-timeStrong (it is said that external event requests can be responded within 1 ms), and the kernel can be very micro (it is said that the minimum can be 8 K), high reliability, so in North America, vxWorks occupies most of the embedded systemsJiangshan district. Especially in systems with high real-time requirements such as communication devices, there is almost no such thing as VxWorks. Many concepts and technologies of VxWorks are sim

When the system image is loaded, the second-stage boot loader transfers control to the kernel image, while the kernel begins to self-extract and initialize. At this stage, the second stage of boot loader checks the hardware of the system, enumerates those additional hardware devices, mounts the root device, and then loads the required k

boot loader checks the system hardware, enumerates the relevant hardware devices, mounts the root device, and then loads the necessary kernel modules. When the work is done, the first User space program (init Open, high-level system initialization is run.This is a concise description of the Linux startup process. Now let's dive into the details of the Linux boot process.System OpenThe system boot phase depends on booting the hardware on the Linux system. On an embedded platform, a boot-boot env

used by the INIT process.Clone_newnet: A network namespace that isolates network resources (/proc/net, IP addresses, network cards, routes, and so on). A background process can run on the same port within a different namespace, and the user can also virtualize a network card.Clone_newns: Mount the namespace, the process runtime can separate the mount point from the system, when using this function, we can achieve the chroot function, and in the security aspect is higher than chroot.The primary

the 102th-place caller of the Los Angeles KIIS FM radio "Friday win Porsche" section. In the ensuing months, Mr. Paulson also overheard the phone call of a Hollywood actress and later attacked military and the FBI. The FBI ended up accusing Mr. Paulson of "series of fraud and money-laundering offences", while Mr. Paulson was sentenced to 51 months in prison, paying a fine of 56,000 dollars for damaged radio stations and a three-year stop in touch with the computer. Now Mr. Paulson is a wired m

Magic packet format is only developed by AMD technology, not universally recognized standa

Interferometer (MI) in a semiconductor optical amplifier (SOAS) based on the cross phase modulation principle, which is recognized as a high speed, The ideal scheme for wavelength conversion in large capacity optical networks. In large-scale use of WDM networks, especially channel scheduling, one wavelength may need to be converted to another wavelength, or the entire band of the transformation. The optical band converter developed by Lucent is base

For broadband wireless access network, the world has three kinds of standards, that is, IEEE Standards, ATM Forum standards and European ETSI standards. European ETSI Broadband Wireless access Network Group research, study the use of wireless access networks, concluded that the use of different needs of the data transmission rate is different. For example, TV on demand requires 1. 5mbit/s to 6mbit/s, online browsing needs 2mbit/s, access to the enterprise network needs 10mbit/s,lan interconnecti

same band. At the same time, the different leading forces lead to different development direction of technology. WLANs are led by data communications rather than by telecommunications vendors. The leaders here are traditional corporate networking companies such as Agere, Cisco, 3Com, IBM, D-link and others. Wireless LAN vendors define mobility with their own LAN experience (like portability). Therefore, they are defined differently than the definitions used by the 3G mobile infrastructure equi

solution is to design the network in order to meet the requirements of network changes and growth to plan accordingly. 1. Investment protection in the future Under normal operating conditions, the new network should not limit system upgrades during the 15 building renovation cycle. A well-designed cabling system can withstand data traffic that is 10~15 times higher than most LAN transmission rates. This will allow the use of new network technologies without altering the wiring system. 2. Gen

important strategic position, for this reason, the Ministry of Information industry has deliberately organized all participating in the Ministry of Information industry 3G technology test system manufacturers and mobile phone manufacturers of UU and IU Interface Interoperability test to verify the interoperability between the system and the mobile phone and system. It is well known that the software versions of wireless systems and mobile phones require version upgrades to add new functionalit

, the most important RTOS include:The first category, traditional Classic RTOs: The most important thing is the Vxworks operating system, as well as its Tornado development platform. VxWorks due to a slightly earlier, real-time very strong (said to be able to respond to external event requests within 1ms), and the core can be very micro (said to be the smallest 8K), high reliability and so on, so in North America, VxWorks occupy the embedded system most of the Xinjiang mountains.

protocol is up), routers are not in a position to perceive changes in network status, and require up to 40s of IGP PDU The Hello agreement is judged. For this reason, the current approach in ISP pop is to connect two routers directly to back-to-back connections through FE and GE cables. 3. The development of L2 Exchange At present, the trend of L2 exchange is gradually moving from LAN range to metropolitan area and even wide area, especially in the most active city area. At present, starting

permissions model is always met. From the data we can see that the number of daily builds has increased by 10 times times, the artifacts generated 10 times times a week, but the storage has only increased twice times, storage optimization is very significant. The most obvious effect is that the time to build CI is reduced by 3,600%, which is amazing. Of course, these are intuitive effects, and some are potential benefits, such as new people familiar with the entire project time is shorter, th

displayed and Linux and an optional initial RAM disk (temporary root file system) are loaded into memory. When the image is loaded, the second stage of the bootloader gives control to the kernel image and the kernel can decompress and initialize it. During this phase, the second stage of the bootloader detects the system hardware, enumerates the system-linked hardware devices, mounts the root device, and then loads the necessary kernel modules. After you complete these operations, start the fir
