解决英文版win7装中文软件乱码
解决英文版win7装中文软件乱码
解决英文Windows7汉字显示乱码
很多用户使用英文Windows7的时候，在安装或者使用某些中文软件的时候，显示的汉字会显示乱码或者"？？？？"又或者"□□□□"。这样肯定是严重影响我们的正常使用啊。
首先，我们进入 [ 控制面板 ] [ Control Panel ] ，点击 [ 更改显示语言 ] [ Change display language ] ，在弹出的窗口中选择 [ 管理 ] [ Administrative ] 选项卡。
在 [ 非 Unicode 程序的语言 ] [ Language for non-Unicode programs ] 下点击 [ 更改系统区域设置 ] [ Change system locale... ] 。
在下拉菜单选择 [ 中文（简体，中国） ] [ Chinese (Simplified, PRC) ] 。
此时计算机会要求重启，选择 [ 现在重启 ] [ Restart now ] ，然后等待计算机重启就可以了。
如果软件还是乱码就卸载然后再安装一下就正常了。

Screen drifting?
root
edit build prop
find "ro.sf.lcd_density=***""
add "view.touch_slop=XX" (XX is 01~30 and means the sensitivity of touch screen, the bigger the more sensitive.)
to avoid the affect of static electricity, use number below 15.
then save, quit, restart.
Now still in testing.............

Suggestion From Foreman about system V vs BSD.
There might be scattered articles about the differences among the many UNIX flavors, but at this point, there are 3 that are in major use. All are based on BSD. You might want see:
1. http://searchenterpriselinux.techtarget.com/answer/The-differences-between-System-V-and-BSD-Unix which requires a free login to see it.
2. https://kb.iu.edu/data/agjs.html for more historical info
You can also do a google search on "system V vs. bsd" spelled exactly like that (without the quotes) and see a few more references. The Wikipedia reference gives the names of the 3 major flavors.

AllSee
Existing gesture-recognition systems consume significant power and computational resources that limit how they may be used in low-end devices. We introduce AllSee, the first gesture-recognition system that can operate on a range of computing devices including those with no batteries. AllSee consumes three to four orders of magnitude lower power than state-of-the-art systems and can enable always-on gesture recognition for smartphones and tablets.
Ambient Backscatter
As computing devices become smaller and more numerous, powering them becomes more difficult; wires are often not feasible, and batteries add weight, bulk, cost, and require recharging/replacement that is impractical at large scales. Ambient backscatter communication solves this problem by leveraging existing TV and cellular transmissions, rather than generating their own radio waves. This novel technique enables ubiquitous communication where devices can communicate among themselves at unprecedented scales and in locations that were previously inaccessible.
(QF:DX>>LL--??)
WiSee
WiSee is a novel interaction interface that leverages ongoing wireless transmissions in the environment (e.g., WiFi) to enable whole-home sensing and recognition of human gestures. Since wireless signals do not require line-of-sight and can traverse through walls, WiSee can enable whole-home gesture recognition using few wireless sources (e.g., a Wi-Fi router and a few mobile devices in the living room).
MIMO Cognitive Systems
This project presents TIMO, the first WiFi receiver that can decode in the presence of high-power unknown cross-technology interference. Traditionally, researchers have addressed cross-technology interference by dynamically searching for and switching to unused frequencies. We approach the problem from a different perspective: can one operate in already used frequencies in the presence of potentially unknown interferers? We build a new cognitive framework for the unlicensed band which allows multi-antenna devices to work in used frequencies.
Password-Free Wireless Security
This project presents tamper-evident pairing, the first wireless pairing protocol that works in-band, with no pre-shared keys, and protects against MITM attacks. The main innovation is a new key exchange message constructed in a manner that ensures an adversary can neither hide the fact that a message was transmitted, nor alter its payload without being detected. Thus, any attempt by an adversary to interfere with the key exchange translates into the pairing devices detecting either invalid pairing messages or an unacceptable increase in the number of such messages.
Securing Medical Implants
Wireless communication has become an intrinsic part of modern implantable medical devices (IMDs). Recent work, however, has demonstrated that wireless connectivity can be exploited to compromise the confidentiality of IMDs’ transmitted data or to send unauthorized commands to IMDs—even commands that cause the device to deliver an electric shock to the patient. The key challenge in addressing these attacks stems from the difficulty of modifying or replacing already-implanted IMDs.
ZigZag Decoding
Collisions are a known problem in wireless networks. The existing approaches address this problem by designing techniques that avoid collisions. This project takes an alternate approach: Instead of trying to avoid collisions, lets embrace collisions. In particular, we present ZigZag decoding, a new WiFi receiver that decodes collisions. The core contribution of ZigZag is a new interference cancellation technique that does not make any assumptions of synchronization, large differences in power, or special codes.

OS structures for NVRAM
In the future, new non-volatile memory technologies, such as phase-change memories and memristors, could change the assumptions underlying the design of current operating systems. We are examining the implications of new, fast non-volatile storage systems on OS mechanisms, functions, and properties, as described in our recent HotOS paper. Faculty: Ceze, Gribble, Levy.

Distributed storage systems
We are pushing the limits of today’s distributed storage systems on several fronts. Scatter, a scalable peer-to-peer key-value storage system, preserves serializable consistency even under adverse conditions. Comet is a distributed key-value store that lets clients inject snippets of code into storage elements, creating an active key-value store that greatly increases the power and range of applications that use distributed storage applications.
BotLab: a Real-Time Botnet Monitoring Platform
BotLab is a platform that continually monitors and analyzes the behavior of spam-oriented botnets. BoLab gathers multiple real-time streams of information about botnets taken from distinct perspectives. By combining and analyzing these streams, BoLab can produce accurate, timely, and comprehensive data about spam botnet behavior.
Privacy-preserving data sharing
Increasing interconnectivity and data sharing can compromise data security and privacy.OneSwarm is a peer-to-peer tool that provides users with explicit control over data privcy by letting them determine how data is to be shared. Instead of sharing data indiscriminately, data shared with OneSwarm can be made public, shared with friends, shared with some friends but not others, and so forth -- an approach we termed friend-to-friend (F2F) data sharing. Faculty: Anderson, Krishnamurthy.
Reverse Traceroute
Traceroute has long had a fundamental limitation that affects all these applications: it does not provide reverse path information. In this project, we address this longstanding limitation by building a reverse traceroute tool. Our tool provides the same information as traceroute, but for the reverse path, and it works in the same case as traceroute, when the user may lack control of the destination.
Synoptic: Studying Logged Behavior with Inferred Models
Computer systems are often difficult to understand and debug. A common way of gaining insight into a system's behavior is to inspect execution logs. Unfortunately, manual inspection of logs is an arduous process. We have developed a tool called Synoptic that helps developers by inferring a concise and accurate system model, in the form of a finite state machine, from execution logs. Synoptic processes the logs that most systems already produce, and it requires developers only to specify a set of regular expressions for parsing the logs. Synoptic models have been used to find new bugs, increase developer confidence in the correctness of their code, and help developers better understand their programs.
SPARTA: mobile device security
The SPARTA project (Static Program Analysis for Reliable Trusted Apps) is building a toolset to verify the security of mobile phone applications.
Trustworthy wireless networks
Current wireless networks do not meet the reasonable privacy expectations of their users. We are: exploring user perceptions and the current state of privacy, investigating link-layer protocols that preserve greater privacy ((SlyFi) , tracking the personal information exposed by applications, and examining privacy at the wireless layer by shaping RF regions. Faculty: Wetherall, Kohno.
File systems for mobile devices
Mobile devices are easily lost or stolen, compromising data and privacy. We have designed a new file system for mobile devices, called Keypad, which provides an audit trail that indicates which files were (or were not) accessed following device loss and lets users disable file reading post-loss, even in the absence of network connectivity. AKeypad paper was presented at the EuroSys Conference, April 2011 and won the Best Student Paper Award. Faculty: Gribble, Kohno, Levy.
Deterministic operating systems
Nondeterministic execution inherent in multithreaded programs severely complicates debugging, testing, and replication. We have proposed a new OS abstraction, called Deterministic Process Groups (DPGs), to ensure fully deterministic (repeatable) execution of arbitrary, unmodified multithreaded programs. We have also developeddOS, a Linux-based implementation of DPGs. Faculty: Ceze, Gribble.
Modern browser and Web systems
The Web has evolved far beyond its original role as a hypertext document delivery system. Today's Web browser increasingly resembles an operating system, in that it executes rich, interactive programs that communicate with cloud-based services.
