杂记 20120107 | Misc Notes 20120107

1. 让c#程序崩溃时的堆栈信息显示行号： 把相应的pdb文件放到同一目录

2. Ubuntu 莫名启动慢，硬盘无反应
我的原因是这个https://bugs.launchpad.net/ubuntu/+source/upstart/+bug/839595
需要在 /etc/network/interfaces 文件中删除 "auto eth0"

3 .Firefox 词典插件推荐 Dictionary Tooltip。配合我常用的dict.cn效果不错
参数
site url: http://dict.cn/mini.php?q=$$
scroll to element: word-key

4. Firefox 显示 MathML 最好安装 STIX 字体， 另推荐安装 Asana 字体

5. gnome-raw-thumbnailer 不能给 Nautilus 正确创建缩略图：
根据 https://bugs.launchpad.net/ubuntu/+source/gnome-raw-thumbnailer/+bug/852923
添加/修改文件 /usr/share/thumbnailers/raw.thumbnailer 为

[Thumbnailer Entry]
Exec=/usr/bin/gnome-raw-thumbnailer -s %s %u %o
MimeType=image/x-canon-cr2;


按自己需要另添加 MimeType 进去

6.GMail 的 Preview Pane 右边阅读区域过于狭窄
在AdBlock里添加规则 
mail.google.com##.Bu:last-child

推荐使用 Element Hiding Helper


1. To show line numbers in the backtrace when a C# program crashes: put the corresponding pdb file into the same directory.

2. Ubuntu starts very slow, and seems that it's not working, but simply waiting
My issue is decribed here: https://bugs.launchpad.net/ubuntu/+source/upstart/+bug/839595
Just delete "auto eth0" from the file /etc/network/interfaces

3. Recommended dictionary add-on for Firefox: Dictionary Tooltip, which works perfect with my favorite dict.cn
Parameters
site url: http://dict.cn/mini.php?q=$$
scroll to element: word-key

4. To get a best view of MathML in Firefox, it's recommended to install the STIX font, and Asana font as well.

5. gnome-raw-thumbnailer cannot create thumbnails for Nautilus
According to https://bugs.launchpad.net/ubuntu/+source/gnome-raw-thumbnailer/+bug/852923
Create/Modify /usr/share/thumbnailers/raw.thumbnailer as

[Thumbnailer Entry]
Exec=/usr/bin/gnome-raw-thumbnailer -s %s %u %o
MimeType=image/x-canon-cr2;


Also include all other necessary MimeTypes

6.The reading pane from the "Preview Pane" in Gmail is too narrow
Add the following rule to AdBlock 
mail.google.com##.Bu:last-child

Recommend to use Element Hiding Helper

Determine Perspective Lines With Off-page Vanishing Point

In perspective drawing, a vanishing point represents a group of parallel lines, in other words, a direction. For any point on the paper, if we want a line towards the same direction (in the 3d space), we simply draw a line through it and the vanishing point. But sometimes the vanishing point is too far away, such that it is outside the paper/canvas. In this example, we have a point P and two perspective lines L1 and L2. The vanishing point VP is naturally the intersection of L1 and L2. The task is to draw a line through P and VP, without having VP on the paper. I am aware of a few traditional solutions: 1. Use extra pieces of paper such that we can extend L1 and L2 until we see VP. 2. Draw everything in a smaller scale, such that we can see both P and VP on the paper. Draw the line and scale everything back. 3. Draw a perspective grid using the Brewer Method. #1 and #2 might be quite practical. #3 may not guarantee a solution, unless we can measure distances/p...

Qubes OS: First Impressions

A few days ago, while browsing security topics online, Qubes OS surfaced—whether via YouTube recommendations or search results, I can't recall precisely. Intrigued by its unique approach to security through compartmentalization, I delved into the documentation and watched some demos. My interest was piqued enough that I felt compelled to install it and give it a try firsthand. My overall first impression of Qubes OS is highly positive. Had I discovered it earlier, I might have reconsidered starting my hardware password manager project. Conceptually, Qubes OS is not much different from running a bunch of virtual machines simultaneously. However, its brilliance lies in the seamless desktop integration and the well-designed template system, making it far more user-friendly than a manual VM setup. I was particularly impressed by the concept of disposable VMs for temporary tasks and the clear separation of critical functions like networking (sys-net) and USB handling (sys-usb) into the...

Exploring Immutable Distros and Declarative Management

My current server setup, based on Debian Stable and Docker, has served me reliably for years. It's stable, familiar, and gets the job done. However, an intriguing article I revisited recently about Fedora CoreOS, rpm-ostree, and OSTree native containers sparked my curiosity and sent me down a rabbit hole exploring alternative approaches to system management. Could there be a better way? Core Goals & Requirements Before diving into new technologies, I wanted to define what "better" means for my use case: The base operating system must update automatically and reliably. Hosted services (applications) should be updatable either automatically or manually, depending on the service. Configuration and data files need to be easy to modify, and crucially, automatically tracked and backed up. Current Setup: Debian Stable + Docker My current infrastructure consists of several servers, all running Debian Stable. System Updates are andled automatically via unattended-upgrades. Se...
