VirtualBox (5 Comments)

昨天升级到Hardy,比较顺利,没有从Feisty到Gutsy那么折腾,回头想想,好像是源的问题,从Feisty到Gutsy,刚好CN99的源坏了,不能用了,真是可惜。洒家觉得CN99的源--快而且完整。下载一直持续在170K左右,2M的宽带,非常不错了。

今天顺手搞了一下VirtualBox,没想到出了问题,如下:

“PIIX3 cannot attach drive to the secondary master
vbox status code: -102 (VERR_FILE_NOT_FOUND)”

重装了VirtualBox还是不能解决问题。(VirtualBox下载地址:http://www.virtualbox.org/download/1.5.6/)找了半天才找到了,按以前的方法找不到了,难道是Sun收购后改了?有什么好改的嘛,麻烦。洒家碰到的这个问题简单的来说就是找不到原来建的VDI文件了,重新指定一下路径就可以了。洒家重装后新建的时候指定了原来建的VDI文件,之后问题解决。

在论坛上搜了一下,没找到结果,倒是把USB的问题解决了。看这里:

洒家碰到的问题,最后在Google里查了一下,还好有人碰到了,不过才一个,呵呵,问题解决了。看这里:

Conky (No Comments)

~$ apt-cache search conky
conky - highly configurable system moni× for X based on ×smo

捣鼓了两天,算是成功了。
~$ sudo apt-get install conky
~$ zcat /usr/share/doc/conky/examples/conkyrc.sample.gz ~/.conkyrc

conky闪烁问题

在安装之后默认状态下并不会闪烁,但是经过配置之后就往往会出现闪烁的问题。解决办法如下:
sudo apt-get install wmctrl
sudo gedit /etc/X11/xorg.conf

在Module段加入一行:
Load “dbe”

保存后退出。

设置conky的配置文件:
gedit ~/.conkyrc

设置以下几项:

own_window yes
own_window_type override
double_buffer yes

保存后退出。
配置如下:
囧☯☎ cat ~/.conkyrc
# Conky sample configuration
#
# the list of variables has been removed from this file in favour
# of keeping the documentation more maintainable.

小问题:当鼠标在Conky上点时,会出现一个大的选择区域,不知道怎么回事,再慢慢折腾。

让conky随机启动的bash
~/bash 囧☯☎ cat conkybash.sh
#!/bin/bash
sleep 15
cd /usr/bin
./conky

在会话里添加这个bash

感谢ee,感谢千禧黑。
code搞不定,换 pre 了

PS:现在code似乎可以了,把上边的pre换为code就可以了,这样就可以直接用 code 的代码了 by 09-29-2009
换code后以前pre的功能不行了,晕死,还得挨个换一次。希望以后能顺利。

踏青 | Spring is coming (6 Comments)

昨天和两个徒弟还有一个同事去踏青去了,春天来了嘛,出去看看咯。
步行到车站,顺便锻炼了一下身体,呵呵。坐车,很快,到了绿色世界。一眼望去,舒服啊,绿油油的一片,就是天气不怎么好,阴天,不过这样也不会很热。有湖,有树,有山,有草,要是在这个地方建个房子应该很棒的,没有闹市的喧哗,享的一份宁静。
那两个徒弟真的太像小孩子了,开心的要命,有的玩就高兴,昨天给她们拍了不少照片。去玩小孩子的溜坡,让她们兴奋不已。可惜昨天没带风筝,那里卖的太贵了,没舍得买。还有让她们遗憾的是没骑到马,没去之前就嚷着要骑马,结果那里没马哦,呵呵,这两个家伙心里就有点不开心,不过有别的玩,还是很开心,小孩子样十足。玩完了就喊累,有的东西吃就开心,真是服了那两个。
趁这个机会我也出去走了走,好久没出去了,整天呆在家里,虽然我喜欢做宅男,但是还是需要出去看看的。
昨天出去玩,前天晚上还上的班,昨天晚上还打牌到凌晨,算了一下,大概36个小时没睡觉,服了自己了,精神真好。

NB的香蕉人 (5 Comments)

昨天晚上吃过饭下楼去散步,最后走到一个小摊,想买点香蕉,拿了一把,称了称,感觉太多了,我说我要一半吧,他就给我了一半,再称了一下,说3斤,我拿到手里掂了掂,哪有3斤啊,2斤都不到,我就问他,这有3斤没,他居然直接告诉我,没3斤。我KAO,这不是明摆着坑人嘛,我说没3斤你就给我说3斤啊,他说我这比超市便宜,我就说你比超市便宜就可以缺斤少两啊,什么人嘛,他还横的说,要就要,不要就拉倒。RI,都差那么多,我还要你个鬼啊。真想打工商局的电话,把它的小摊给收拾了,可惜是晚上9点多了。现在的社会啊,越来越差了。都没道德了,有时候还挺同情那些做小生意,摆小摊的,可现在,哎…

NND,以后再也不到小摊买东西了,你以为老子好欺负啊。

‘End of Life’ announcement for Ubuntu 6.10 (5 Comments)

LONDON, March 25, 2008 - Ubuntu announced the release of 6.10 almost 18 months ago, on October 26, 2006. As with the earlier releases, Ubuntu committed to ongoing security and critical fixes for a period of 18 months. The support period is now nearing its end and Ubuntu 6.10 will reach end of life on Friday April 25th, 2008. At that time, Ubuntu Security Notices will no longer include information or updated packages for Ubuntu 6.10.

The supported upgrade path from Ubuntu 6.10 is via Ubuntu 7.04. Instructions and caveats for the upgrade may be found at https://help.ubuntu.com/community/FeistyUpgrades. Note that upgrades to version 7.10 and beyond are only supported in multiple steps, via an upgrade first to 7.04, then to 7.10. Both Ubuntu 7.04 and Ubuntu 7.10 continue to be actively supported with security updates and select high-impact bug fixes. All announcements of official security updates for Ubuntu releases are sent to the ubuntu-security-announce mailing list, information about which may be found at https://lists.ubuntu.com/mailman/listinfo/ubuntu-security-announce.

Since its launch in October 2004 Ubuntu has become one of the most highly regarded Linux distributions with millions of users in homes, schools, businesses and governments around the world. Ubuntu is Open Source software, costs nothing to download, and users are free to customise or alter their software in order to meet their needs.

时间过的真快,又一个版本停止支持了,希望Ubuntu越来越好。

第三届CSS裸奔节就在今年4月9日!活动的目的是推动Web标准。简洁为美。使用正确的(x)html,语义标记,良好的层次结构。暂时把页面设计抛弃,直接展示。

虽然不是太懂CSS,而且也不做网页方面的,不过看着好玩,记一下。

书到用时方恨少 事非经过不知难 (4 Comments)

【鉴赏】这是一副劝勉联,对联虽浅显易懂,却蕴含着深刻的哲理。如果说上联是劝勉人们要“贵学”,那么下联“事非经过不知难”,就是强调“行”的重要性,光“ 学”不“行”终是无益。宋代陆游在《冬夜读书示子聿》中云:“纸上得来终觉浅,绝知此事要躬行”,明周立说:“一语不能践,万卷徒空虚”,也是此理。宋代的朱熹和清代的王夫之更把“知”“行”关系说得明白。朱熹说:“论先后,知为先;论轻重,行为重”,王夫之在《尚书引义》中云:“知之非艰,行之惟艰。……且夫知也者,因以行为功者也;行也者,不以知为功者也。行焉可以得知之效也,知焉未可以得行之效也”,均是说“知”“行”的关系,“知”是手段,“行”是目的,不“行”,无以奏“知”之效,也无以知“事”之艰难,免不了落个“纸上谈兵”的下场。
本联用明白易懂的语言,将“知”“行”有机地结合起来,给人以深刻的感受。
本联在艺术上的特色是用词平淡,不事雕琢,雅俗共赏,语言自然却韵味无穷,深得孟浩然《春晓》的艺术真谛。本联对仗也工整自然,意义相对,尤其深刻、贴切,故千百年来成为劝勉联中的精品。

勉励一下自己

Hardy Heron | 8.04 Ubuntu (5 Comments)

前几天下了个alpha6的KUbuntu,在VirtualBox里试了试,还是不习惯哦,只是想看看KDE4而已,觉得没那么必要折腾了。今天又下了个beta版的Ubuntu,打算刻盘安装,不网络升级了,从7.04升到8.04,太麻烦了,还不如刻盘重新安装呢。而且打算以后一直用8.04,除非有更吸引我的地方。8.04好歹也是个LTS,肯定比一般的要稳定一些。还是习惯gnome,就一直用这个吧,臃肿就臃肿吧,谁叫我懒呢,呵呵~~~

我发现我只喜欢用4月份发行的,6.06–>7.04–>8.04,跳过了6.10和7.10

保持自己的习惯吧
