(转)Ubuntu 7.10中文输入法问题解决


升级到ubuntu 7.10,有可能会遇到修改文件名时不能输入,在firefox中不能光标跟随,在gaim,pidgin,amsn,emesene,eva,gtalk等聊天软件不能输入文字等等的问题.解决方法如下:

# im-switch -s scim -z default
# sudo apt-get install scim-qtimm
# sudo apt-get install scim scim-pinyin scim-tables-zh im-switch scim-qtimm scim-bridge scim-bridge-client-gtk scim-bridge-client-qt scim-bridge-agent

编辑im-switch生成的scim配置文件
# gksu gedit /etc/X11/xinit/xinput.d/scim
将默认的 GTK_IM_MODULE=scim 修改为 GTK_IM_MODULE="scim-bridge"。保存退出.

在scim输入法中进行了如下设定：

scim设置－>全局设置－>将预编辑字符串嵌入到客户端中 前的勾去掉
scim设置->gtk->嵌入式候选词标的勾去掉.

重启scim

打开终端,输入 pkill scim
然后输入 scim -d
OK

输入法初始化的问题。用下列命令把scim改为默认输入法控制器：
$ sudo cp /etc/X11/xinit/xinput.d/default /etc/X11/xinit/xinput.d/default.bak
$ sudo cp /etc/X11/xinit/xinput.d/scim /etc/X11/xinit/xinput.d/default

我自己使用的，对于还没计划升级电视机到HDTV的来说，我觉得非常值得推荐

DVX 555
http://www.dealsdirect.com.au/p/ ... ital-tv-hard-drive/

50元的价格，买一个机顶盒已经不错，更不错的是可以放入一个老IDE硬盘，发挥余热变成录像机。他的录像功能不错，可以通过EPG节目预告来预约录像，不录像的时候，如果启用time shift功能，可以对目前的电视节目暂停，倒带，快进。。从而跳过广告，或者看回原来的内容。

澳洲好像后年之前会停止模拟的电视广播了，这意味着所有的老式电视，如果不加装机顶盒，将看不到电视节目。加装机顶盒，还有其他好处，比如在接受信号不完美的地方也能看到DVD质量清晰的节目，可以启用字幕，看节目预告等等。

另外这个机顶盒，虽然不支持HD播放，但实际上可以录制HD节目，然后把文件弄出来在电脑上面放，不过操作比较麻烦，我还没有尝试过。

由于收到两起指责iPhone广告误导消费者的投诉，英国广告标准管理局（ASA）日前禁止了一则苹果iPhone广告在英国播出。

这则广告展示了iPhone的各种网络功能，内容假想一个要到南非旅游的用户，首先查看开普敦天气，随后用Google Map指出到伦敦希思罗机场的路线，接着到浏览器查看当地旅馆海景房图片，最后在查阅股票行情看自己是否负担得起这次旅行。最终，画外音总结：“这就是为什么我们把互联网的所有部分都放在iPhone里的原因。”

但正是这则广告，让两位英国消费者投诉：iPhone并不支持Flash和Java，因此无法正常使用许多网站，宣称iPhone支持互联网所有功能显然有误导消费者之嫌。在该广告上线前，当地审查部门在广告商进行现场演示并作出保证后开出了绿灯。但现在ASA认为，该广告让用户认为iPhone可以访问所有网站并完整显示，因此以“误导消费者对iPhone互联网功能印象”的原因将该广告禁播。

苹果对此的解释是，该广告的目的是演示iPhone对所有网站的访问能力，而不像许多手机一样仅能访问WAP网站。iPhone中的Safari浏览器实在开放互联网标准的基础上构建的，Flash和Java并非开源标准，因此他们并不能保证支持“市场上的所有第三方技术”。广告中的所有内容都不是基于Flash或Java，“互联网的所有部分”指的是网站可访问，并不是“所有功能”。

FROM: http://weblogs.mozillazine.org/roadmap/archives/2008/08/tracemonkey_javascript_lightsp.html

TraceMonkey: JavaScript LightspeedI'm extremely pleased to announce the launch of TraceMonkey, an evolution of Firefox's SpiderMonkey JavaScript engine for Firefox 3.1 that uses a new kind of Just-In-Time (JIT) compiler to boost JS performance by an order of magnitude or more.

TraceMonkey是Firefox SpiderMonkey (Firefox现在的Javascript执行引擎)的革新版本，将在Firefox3.1中出现在大家面前。 这个版本的Javascript引擎将像JVM一样通过引入JIT技术来提升Javascript的性能。

ResultsLet's cut straight to the charts. Here are the popular SunSpider macro- and micro-benchmarks average scores, plus results for an image manipulation benchmark and a test using the Sylvester 3D JS library's matrix multiplication methods:
测试结果让人非常惊喜啊，各个方面都有显著的性能提升，看来以后用gamil能更快了！
Here are some select SunSpider micro-benchmarks, to show some near-term upper bounds on performance: This chart shows speedup ratios over the SpiderMonkey interpreter, which is why "empty loop with globals" (a loop using global loop control and accumulator variables) shows a greater speedup -- global variables in JavaScript, especially if undeclared by var, can be harder to optimize in an interpreter than local variables in a function. Here are the fastest test-by-test SunSpider results, sorted from greatest speedup to least: The lesser speedups need their own chart, or they would be dwarfed by the above results: (Any slowdown is a bug we will fix; we're in hot pursuit of the one biting binary-trees, which is heavily recursive -- it will be fixed.) With SunSpider, some of the longest-running tests are string and regular-expression monsters, and since like most JS engines, we use native (compiled C++) code for most of the work, there's not as much speedup. Amdahl's Law predicts that this will bound the weighted-average total Sunspider score, probably to around 2. No matter how fast we JIT the rest of the code, the total score will be... 2. But this is only a start. With tracing, performance will keep going up. We have easy small linear speedup tasks remaining (better register allocation, spill reduction around built-in calls). We will trace string and regular expression code and break through the "2" barrier. We will even trace into DOM methods. The tracing JIT approach scales as you move more code into JS, or otherwise into view of the tracing machinery. Finally, schrep created a screencast (UPDATE: link fixed) that visually demonstrates the speedup gained by TraceMonkey. These speedups are not just for micro-benchmarks. You can see and feel them. How We Did ItWe've been working with Andreas Gal of UC Irvine on TraceMonkey, and it has been a blast. We started a little over sixty days (and nights ;-) ago, and just yesterday, shaver pushed the results of our work into the mozilla-central Hg repository for inclusion in Firefox 3.1. The JIT is currently pref'ed off, but you can enable it via about:config -- just search for "jit" and, if you are willing to report any bugs you find, toggle the javascript.options.jit.content preference (there's a jit.chrome pref too, for the truly adventurous).
Before TraceMonkey, for Firefox 3, we made serious performance improvements to SpiderMonkey, both to its Array code and to its interpreter. The interpreter speedups entailed two major pieces of work:

• Making bytecode cases in the threaded interpreter even fatter, so the fast cases can stay in the interpreter function.
• Adding a polymorphic property cache, for addressing properties found in prototype and scope objects quickly, without having to look in each object along the chain.

I will talk about the property cache and the "shape inference" it is based on in another post.
By the way, we are not letting moss grow under our interpreter's feet. Dave Mandelin is working on a combination of inline-threading and call-threading that will take interpreter performance up another notch. While doing this Firefox 3 work, I was reminded again of the adage:

Neurosis is doing the same thing over and over again, expecting to get a different result each time.

But this is exactly what dynamically typed language interpreters must do. Consider the + operator:
a = b + c;Is this string concatenation, or number addition? Without static analysis (generally too costly), we can't know ahead of time. For SpiderMonkey, we have to ask further: if number, can we keep the operands and result in machine integers of some kind?
Any interpreter will have to cope with unlikely (but allowed) overflow from int to double precision binary floating point, or even change of variable type from number to string. But this is neurotic, because for the vast majority of JS code, in spite of the freedom to mutate type of variable, types are stable. (This stability holds for other dynamic languages including Python.) Another insight, which is key to the tracing JIT approach: if you are spending much time in JS, you are probably looping. There's simply not enough straight line code in Firefox's JS, or in a web app, to take that much runtime. Native code may go out to lunch, of course, but if you are spending time in JS, you're either looping or doing recursion. The Trace Trees approach to tracing JIT compilation that Andreas pioneered can handle loops and recursion. Everything starts in the interpreter, when TraceMonkey notices a hot loop by keeping cheap count of how often a particular backward jump (or any backward jump) has happened. for (var i = 0; i < BIG; i++) {    // Loop header starts here:    if (usuallyTrue())        commonPath();    else        uncommonPath();}Once a hot loop has been detected, TraceMonkey starts recording a trace. We use the Tamarin Tracing Nanojit to generate low-level intermediate representation instructions specialized from the SpiderMonkey bytecodes, their immediate and incoming stack operands, and the property cache "hit" case fast-lookup information. The trace recorder completes when the loop header (see the comment in the code above) is reached by a backward jump. If the trace does not complete this way, the recorder aborts and the interpreter resumes without recording traces. Let's suppose the usuallyTrue() function returns true (it could return any truthy, e.g. 1 or "non-empty" -- we can cope). The trace recorder emits a special guard instruction to check that the truthy condition matches, allowing native machine-code trace execution to continue if so. If the condition does not match, the guard exits (so-called "side-exits") the trace, returning to the interpreter at the exact point in the bytecode where the guard was recorded, with all the necessary interpreter state restored. If the interpreter sees usuallyTrue() return true, then the commonPath(); case will be traced. After that function has been traced comes the loop update part i++ (which might or might not stay in SpiderMonkey's integer representation depending on the value of BIG -- again we guard). Finally, the condition i < BIG will be recorded as a guard. // Loop header starts here:inlined usuallyTrue() call, with guardsguard on truthy return valueguard that the function being invoked at this point is commonPathinlined commonPath() call, with any calls it makes inlined, guardedi++ code, with overflow to double guardi < BIG condition and loop-edge guardjump back to loop headerThus tracing is all about speculating that what the interpreter sees is what will happen next time -- that the virtual machine can stop being neurotic. And as you can see, tracing JITs can inline method calls easily -- just record the interpreter as it follows a JSOP_CALL instruction into an interpreted function. One point about Trace Trees (as opposed to less structured kinds of tracing): you get function inlining without having to build interpreter frames at all, because the trace recording must reach the loop header in the outer function in order to complete. Therefore, so long as the JITted code stays "on trace", no interpreter frames need to be built. If the commonPath function itself contains a guard that side-exits at runtime, then (and only then) will one or more interpreter frames need to be reconstructed. Let's say after some number of iterations, the loop shown above side-exits at the guard for usuallyTrue() because that function returns a falsy value. We abort correctly back to the interpreter, but keep recording in case we can complete another trace back to the same loop header, and extend the first into a trace tree. This allows us to handle different paths through the control flow graph (including inlined functions) under a hot loop. What It All MeansPulling back from the details, a few points deserve to be called out:

• We have, right now, x86, x86-64, and ARM support in TraceMonkey. This means we are ready for mobile and desktop target platforms out of the box.
• As the performance keeps going up, people will write and transport code that was "too slow" to run in the browser as JS. This means the web can accomodate workloads that right now require a proprietary plugin.
• As we trace more of the DOM and our other native code, we increase the memory-safe codebase that must be trusted not to have an exploitable bug.
• Tracing follows only the hot paths, and builds a trace-tree cache. Cold code never gets traced or JITted, avoiding the memory bloat that whole-method JITs incur. Tracing is mobile-friendly.
• JS-driven <canvas> rendering, with toolkits, scene graphs, game logic, etc. all in JS, are one wave of the future that is about to crest.

TraceMonkey advances us toward the Mozilla 2 future where even more Firefox code is written in JS. Firefox gets faster and safer as this process unfolds.
I believe that other browsers will follow our lead and take JS performance through current interpreter speed barriers, using just-in-time native code compilation. Beyond what TraceMonkey means for Firefox and other Mozilla projects, it heralds the JavaScript Lightspeed future we've all been anticipating. We are moving the goal posts and changing the game, for the benefit of all web developers. AcknowledgmentsI would like to thank Michael Franz and the rest of his group at UC Irvine, especially Michael Bebenita, Mason Chang, and Gregor Wagner; also the National Science Foundation for supporting Andreas Gal's thesis. I'm also grateful to Ed Smith and the Tamarin Tracing team at Adobe for the TT Nanojit, which was a huge boost to developing TraceMonkey.
And of course, mad props and late night thanks to Team TraceMonkey: Andreas, Shaver, David Anderson, with valuable assists from Bob Clary, Rob Sayre, Blake Kaplan, Boris Zbarsky, and Vladimir Vukićević.

1。lvs
2. 后端server
如果用动态 后面还要有
3. 后端数据库
所以他说的瘫是 lvs瘫痪 or 后端server瘫痪 or后端数据库瘫痪？
如果是3的话 可能几个并发就把数据库搞瘫痪了如果sql写的很滥。 我遇到过 10个并发把我们数据库搞瘫痪的。

纯粹静态的境况下。
曾经有用一台alteon 2424 做到60万的session 还没有到alteon cpu瓶颈的地步 但带宽满了1G 后面是20台 IIS 静态页面. iis上显示的session每台2万多（apache 当时的j这方面地确比不上iis）.

对于http 并发是个很模糊的概念。
我所说的session是 指 已经establish的connection. 当时的带宽 已经是下行 1G了 平线。并发到底多少呢 只能用log分析了。可惜当时的log 分析我从来也不看。。。。但我想几万并发是肯定有的。
