网络工程师

我是2005年上半年参加了全国软考的网络工程师的考试,最后戏剧性的以上午45下午50的成绩通过了。今天在搜索一些资料时竟然发现了思达网校的bbs 05年上半年网络工程师江苏成绩统计表(通过的名单),里面也有我的名字——管建丰。



那一届江苏共有2092名考生参加了考试(缺考的应该还有一部 分),上午45/下午45以上人数为161人,总数 2092,通过率为7.696%、上午45/下午46以上人数为130人,总数2092人,通过率6.214%

2005年下半年参加(115日)考试的人数为11,全年共为21.8万人,创下历史新高。

我的同事在04年下半年参加了网络工程师的考试,当时都不知道有这个考试,后来他通过了,并且这张证在职称上也对他起了些作用。于是在05年过年后我就想自己也拼一下看。当时决心下的很好,后来就没心思看书,最后还是下定决心,花了一个月时间。我的工作就是网络管理相关的,所以一开始我就对下午的试题就很有信心,上午的就很担心,全部是理论的选择题, 应该是我没认真看那本教程的原因,因为一般都说上午的试题教程上都有。那天考完后自己就感觉,如果上午能过,这考试应该就没问题了。果然,最终成绩上午正好压及格线45分(70满分),看了江苏的成绩,发现和我一样单科是45分的也不少,33个。还有三位上午下午都是45分,比我还厉害,呵。

DragonFly BSD 1.4.0 发布

DragonFly BSD 1.4.0 已经被发布。根据其版本注释,新版本的变更包括吸收了NetBSD 的 pkgsrc 和 Citrus 等成果,其引人注意的特征还包括引入了独自的NTPD等。DragonFly BSD 1.4.0 不支持 FreeBSD 的 ports 系统。   — 消息来自ChinaUnix.net

它是从FreeBSD4-STABLE分支出来的一个项目,侧重于轻量级但能高效能的及多处理器支持的一个操作系统。维基中文百科上写到:

DragonflyBSD脫胎自FreeBSD4系列。

由於FreeBSD team將於FreeBSD4.11後不再推出新的4系列版本(僅做安全性更新),而新的FreeBSD 5系列初期又有效能及穩定性等等的質疑,因此部分社群成員變另外成立分支計劃,是為DragonflyBSD。

另外DragonflyBSD吸收了一些在FreeBSD 5不採用的構想,因此不少人認為DragonflyBSD前途大有可為。

《我的feedburner解析错误?》续——问题解决

星期五发现我的feedburner不能正常显示,一直以为是feedburner的问题,过了两天今天早上过来还没正常,正准备给feedburner发封信,想在试着访问的时候,发现了和星期五不一样的错误信息:

XML解析错误:对无效字符数字的引用
位置:http://feeds.feedburner.com/funpower
行:17,列:47<a href="http://flashgot.net/" title="A??(??}

我看到了http://flashgot.net这个地址,一下就想起了上星期四发的文章《firefox扩展》,其实当初发布文章时就有点不对劲,发布完总有些内容不能正常显示。想到有可能是用ListZilla导出firefox扩展的问题。难道是donews rss问题?立刻访问,果然不行,看来问题不在feedburner上。立刻将《firefox扩展》文章内容复制到windows记事本中然后再再记事本复制回文章中(去除文章的所有格式一般我就用这个方法),再添加一些链接,重新发布文章。

访问我的feedburner还是不行,访问donews rss,可以正常显示,应该是feedburner还没更新。问题应该得到解决。

是我当时用ListZilla导出有问题,还是ListZilla本身的问题? 不知道其他朋友有没有遇到过这种事?

PS:昨天将NOKIA-7610买回来了,行货,2850元(江苏无锡)。差点就买了SAMSUNG-D608水货,价格2700元。

使用博索引用统计

今天将原来的引用统计truefresco.org换成了
博索引用统计
(Booso Refer Stat System)。

当您的网页被浏览次数与日俱增的时候,您一定也想知道,访客们都是怎么到达您的网页的吧。

博索引用统计
(Booso Refer Stat System)就是一个专门监测网页引用来源的服务,您只需要在页面中嵌入一行代码就可以实时的显示一个统计列表,表明访问者从哪个页面链接到了您的网页。
统计列表的内容包括:反向链接的URL地址,网页标题,引用次数,最后引用时间。

我的feedburner解析错误?

发现我的feedburner解析错误,但访问同帐号下的另外一个正常。奇怪了?难道是我这边的问题。

firefox扩展

这两天一直看到有朋友利用ListZilla将自己的firefox扩展贴出来,今天也花了些时间将自己的firefox扩展了一下,用了以后才发现原来firefox的扩展有这么多。

我的firefox扩展列表:

禁止某ip使用socks5服务

继上次架设完FreeBSD6.0Release+Squid+Socks5服务器架设笔记后,服务器运行基本正常,但今天发现socks5服务不能使用。以为是socks5进程死掉了,就运行stopsocks -KILL,将socks5停止。然后使用socks5命令重新开启socks5服务。可没过多久,socks5服务又不能用了。马上用netstat  -nat命令查看网络连接情况,发现有一ip 172.16.1.199开启了无数进程发向服务器的1080端口。为了大局,决定暂时先停止此ip的连接,没有过socks5禁止过某一ip,所以一开始没顺利禁止此ip,后来看了如何在Solaris 9系统下实现socks5代理一文后才了解如何禁止。

其实很简单,socks5.conf中开启某段ip是用permit字段,将permit改成deny就可以,方法如下:

将/usr/local/etc/socks5.conf:

auth – – –
permit – – 172.16. – – –
set SOCKS5_NOIDENT
set SOCKS5_V4SUPPORT

改成以下内容即可:

deny  – – 172.16.1.199/255.255.255.255 – – –
auth  – – –
permit  – – 172.16. – – –
set SOCKS5_NOIDENT
set SOCKS5_V4SUPPORT

www.freebsd.org可以正常访问了

刚刚试着访问www.freebsd.org,可以访问。看来误会解除了,HAPPY!

诺基亚7610 这机子如何?现在又在看三星D608了

03年2月买的摩托罗拉e360,最近一直出问题,老自动关机,所以准备过年时重新装备一个。目前选了诺基亚7610,想问问用过的朋友,这机子如何?谢谢。

2006-1-6更新:看了几天的资料,眼都花了。前天一朋友买了另外一朋友的三星d608水货手机,价格2800左右。试了一下机子,不错。三星的不太了解,但都说它的水货货质量不错。再考虑考虑了要。

The Ultimate Guide to Google Services

Anyone who has ever used the internet probably knows about Google’s web search, but did you know that Google does a lot more? We’ve discussed many Google services on TipMonkies before, but there are some which some of you may not be aware of. Read the full article to get the giant list of Google services and what each does. We’ll try to keep this list up-to-date as Google begins rolling out more services (because you know they will).

Here’s the big list of Google’s services:

  • Add to Google lets publishers create a custom “Add to Google” button for their RSS feeds. When a user clicks the button, they can choose to either add the feed to Google Reader, or the Google Homepage service.
  • Blogger is Google’s blog-hosting and creation service which seems to be very popular on the web because of the price (free) and ease of use.
  • Froogle is Google’s product search engine that you can use to find the cheapest price for a product.
  • GMail (or Google Mail) is Google’s popular email service, that gives you over 2 gigabytes of storage.
  • Google AdSense is Google’s contextual advertising service, popular among many websites. Google also released Onsite Advertiser Sign-Up on November 21, 2005 which lets advertisers buy ads on a site directly from the Google Ads on that page.
  • Google AdWords is the other side of AdSense. While AdSense lets publishers put ads on their site, someone has to pay for those ads, and AdWords connects companies with publishers so you can make a little bit of money.
  • Google Alerts are e-mail updates to particular searches you do on Google. Pretty useful for monitoring websites or news.
  • Google Analytics crawls your website and keeps track of your visitors through a small piece of Javascript. Great tool for webmasters trying to improve their stats and AdSense revenue.

  • Google Answers lets you hire someone to research a topic or answer a question for you.
  • Google Base looks like its going to be Google’s massive content library, with all sorts of content, uploadable by anyone. Oddly enough, it sounds like EPIC and Google Grid mentioned in this video. Many people are comparing this service to Craigslist.
  • Google Blog Search is very much like the web search service but letting search only through various blogs around the web.
  • Google Book Search allows you to search though books that Google has scanned into their database.
  • Google Catalogs is a search engine for mail-order catalogs.
  • Google Click-to-Call lets users call advertisers directly from Google search results, for free, at Google’s expense.
  • Google Code is Google’s effort to promote and contribute to Open Source software.
  • Google Compute exists as a part of the Google Toolbar and uses your computer’s idle time (when you’re not using it) to compute data from distributed computing projects like Folding@Home.
  • Google Deskbar is essentially an embedded IE window in your Window Taskbar that you can search Google from.
  • Google Desktop is similar to apps like Konfabulator or Dashboard but not as attractive. It offers various widgets and a sidebar which let you do things like searches, aggregate feeds, write notes, check weather, and more.
  • Google Directory which is similiar to Yahoo’s and dmoz’s services, letting you search by category.
  • Google Earth is a desktop application which is basically Google Local on steroids.
  • Google Groups allows you to create a mailing list, read Usenet posts, and generally collaborate with others who share a similar interest.
  • Google Homepage is a webpage which lets you add various widgets like weather, news, horoscopes and more, much like Netvibes.
  • Google Image Search is Google’s slightly-lesser-known service to search for images.
  • Google Labs highlights all the projects Google is working on for future release.
  • Google Local combines data from Google Maps with information on local businesses and venues.
  • Google Maps is a mapping service which also provides driving directions to and from different locations. The service is only available in a few countries (mainly the U.S.) but support for other countries is expected in the future. Google Maps has become quite popular lately thanks to a readily available API which lets people create their own maps.
  • Google Mobile is similiar to Google SMS, but using WAP instead.
  • Google Movie Showtimes lets you type in a zip code or address, and it will find movie theaters and showtimes near that area.
  • Google News is a news portal, aggregated by Google’s computers. Everything is done by machines, so no human interaction.
  • Google Reader is a new product which acts as a web-based RSS reader.
  • Google Ridefinder lets you easily find taxis in some of the major cities around the United States.
  • Google Scholar searches things such as theses, papers, and other research and technical information.
  • Google Search History is technically part of the Google Homepage service, but does have its own page so it warrants a mention. Basically, if you sign in with a Google account, Google will keep track of all your searches done via its web search engine.
  • Google Send to Phone is a little Firefox extension which lets you send text messages to mobile phones via SMS.
  • Google Sitemap helps create particular searches for a web address which can be very useful for webmasters looking to index their own site, or see who is linking to it.
  • Google SMS allows you to access many Google services through your mobile phone through text messaging (message GOOGL to learn more).
  • Google Store isn’t really a service, but rather a place to buy some cool Google merchandise.
  • Google Suggest is just an extension to the normal Google web search engine, but with autocomplete functionality to your searches making it a little easier to find what you need. There is also

    a Firefox extension available.

  • Google Talk is Google’s IM and VoIP program running on the Jabber network. You need a Gmail account to use this.
  • Google Toolbar is the swiss army knife of toolbars, if ever there was one letting your use the various Google web services from your toolbar, as well as offering other interesting information like a site’s PageRank and more.
  • Google Language Tools lets you translate a phrase or entire website, as well as giving you access to web search in different languages, or the ability to search for a particular something in just one language.
  • Google Video and Google Video Upload offer an archive of freely available video clips.
  • Google Web Accelerator supposedly helps load web pages faster, but there have been security and privacy issues raised about this application.
  • Google Web Search is the familiar web search. It also allows you to access certain functions like a calculator, a stock tracker, word definitions, travel information, weather, and more by simply searching for that information (for example, define onomatopoeia or weather 90210). These are not standalone services but a part of web search, which is why I’ve added them here and not into their own section. Additionally, there is the Advanced Search feature for…well…advanced searches which could be more precise than normal searches.
  • Hello is a small IM client which is used in conjunction with Picasa to share pictures with family and friends.
  • Orkut is a networking site similar to Frienster or MySpace, except it is invite only, so if you want to join it, you’ll have to know a guy, who knows a guy.
  • Picasa is a fantastic digital photo organizer application for your desktop.

Now that you know about many of Google’s services, get out there and start Googling!
