ditaa

ideame — Sun, 03 Nov 2013 07:21:00 GMT

ditaa is a small command-line utility written in Java, that can
convert diagrams drawn using ascii art ('drawings' that contain
characters that resemble lines like | / - ), into proper
bitmap graphics. This is best illustrated by the following
example -- which also illustrates the benefits of using ditaa in
comparison to other methods :)

    +--------+   +-------+    +-------+
    |        | --+ ditaa +--> |       |
    |  Text  |   +-------+    |diagram|
    |Document|   |!magic!|    |       |
    |     wmqeeuq|   |       |    |       |
    +---+----+   +-------+    +-------+
        :                         ^
        |       Lots of work      |
        +-------------------------+

After conversion using ditaa, the above
file becomes:

ditaa interprets ascci art as a series of open and closed
shapes, but it also uses special markup syntax to increase the
possibilities of shapes and symbols that can be rendered.

ditaa is open source and free software (free as in free
speech), since it is released under the GPL license.

BUT WHY? Does this thing have any real use?

There are several reasons why I did this:

Simply for hack value. I wanted to know if/how it could be
done and how easily.
Aesthetic reasons and legacy formats: there are
several old FAQs with ascii diagrams lying out there. At this
time and age ascii diagrams make my eyes hurt due to their
ugliness. ditaa can be used to convert them to something
nicer. Although ditaa would not be able to convert all of them
(due to differences in drawing 'style' in each case), it could
prove useful in the effort of modernising some of those
documents without too much effort. I also know a lot of people
that can make an ascii diagram easily, but when it gets to using
a diagram program, they don't do very well. Maybe this utility
could help them make good-looking diagrams easily/quickly.
Embedding diagrams to text-only formats: There is a
number of formats that are text-based (html, docbook, LaTeX,
programming language comments), but when rendered by other
software (browsers, interpreters, the javadoc tool etc), they
can contain images as part of their content. If ditaa was
intergrated with those tools (and I'm planning to do the javadoc
bit myself soon), then you would have readable/editable diagrams
within the text format itself, something that would make things
much easier. ditaa syntax can currently be embedded to HTML.
Reusability of "code": Suppose you make a diagram in
ascii art and you render it with version 0.6b of ditaa. You keep
the ascii diagram, and then version 0.8 comes out, which
features some new cool effects. You re-render your old diagram
with the new version of ditaa, and it looks better, with zero
effort! In that sense ditaa is a diagram markup language, with
very loose syntax.

Download

(((-intro-))) (((-download-))) (((-usage and syntax-))) (((-friends-))) (((-contact-)))

The latest version of ditaa can be obtained from its SourceForge project page.

You can checkout the code using:

svn co https://ditaa.svn.sourceforge.net/svnroot/ditaa ditaa

You can also browse the code online.

Usage and syntax

(((-intro-))) (((-download-))) (((-usage and syntax-))) (((-friends-))) (((-contact-)))

Command line

You need the latest Java runtimes (JRE) to use ditaa. The best
anti-aliasing can be achieved using Java 1.5 or higher.

To start from the command line, type (where XXX is the version number):

java -jar ditaaXXX.jar

You will be presented with the command-line options help:

 -A,--no-antialias          Turns anti-aliasing off.
 -d,--debug                 Renders the debug grid over the resulting
                            image.
 -E,--no-separation         Prevents the separation of common edges of
                            shapes. You can see the difference below:

+---------+ \| cBLU \| \| \| \| +----+ \| \|cPNK\| \| \| \| +----+----+
Before processing	Common edge separation (default)	No separation (with the `-E` option)

-e,--encoding The encoding of the input file. -h,--html In this case the input is an HTML file. The contents of the

 tags
                            are rendered as diagrams and saved in the
                            images directory and a new HTML file is
                            produced with the appropriate  tags.
                            See the HTML section.
    --help                  Prints usage help.
 -o,--overwrite             If the filename of the destination image
                            already exists, an alternative name is chosen.
                            If the overwrite option is selected, the image
                            file is instead overwriten.
 -r,--round-corners         Causes all corners to be rendered as round
                            corners.
 -s,--scale          A natural number that determines the size of
                            the rendered image. The units are fractions of
                            the default size (2.5 renders 1.5 times bigger
                            than the default).
 -S,--no-shadows            Turns off the drop-shadow effect.
 -t,--tabs            Tabs are normally interpreted as 8 spaces but
                            it is possible to change that using this
                            option. It is not advisable to use tabs in
                            your diagrams.
 -v,--verbose               Makes ditaa more verbose.

Syntax

Round corners

If you use / and \ to connect corners, they are rendered as
round corners:

/--+ \| \| +--/
Before processing	Rendered

Color

Color codes can be used to add color to the diagrams. The
syntax of color codes is

cXXX

where XXX is a hex number. The first digit of the number
represents the red compoment of the color, the second digit
represents green and the third blue (good ol' RGB). See below for
an example of use of color codes:

/----\ /----\ \|c33F\| \|cC02\| \| \| \| \| \----/ \----/ /----\ /----\ \|c1FF\| \|c1AB\| \| \| \| \| \----/ \----/
Before processing	Rendered

This can become a bit tedious after a while, so there are (only
some for now) human readable color codes provided:

Color codes /-------------+-------------\ \|cRED RED \|cBLU BLU \| +-------------+-------------+ \|cGRE GRE \|cPNK PNK \| +-------------+-------------+ \|cBLK BLK \|cYEL YEL \| \-------------+-------------/
Before processing	Rendered

As you can see above, if a colored shape contains any text, the
color of the text is adjusted according to the underlying
color. If the undelying color is dark, the text color is changed
to white (from the default black).

Note that color codes only apply if they are within closed
shapes, and they have no effect anywhere outside.

Name	Original	Comment
Document	+-----+ \|wmqeeuq \| \| \| \| \| +-----+	Symbol representing a document.
Storage	+-----+ \|{s} \| \| \| \| \| +-----+	Symbol representing a form of storage, like a database or a hard disk.
Input/Output	+-----+ \|{io} \| \| \| \| \| +-----+	Symbol representing input/output.

Dashed lines

Any lines that contain either at least one = (for horizontal
lines) or at least one : (for vertical lines) are rendered as
dashed lines. Only one of those characters can make a whole line
dashed, so this feature "spreads". The rationale behind that is
that you only have to change one character to switch from normal
to dashed (and vice versa), rather than redrawing the whole
line/shape. Special symbols (like document or storage symbols) can
also be dashed. See below:

----+ /----\ +----+ : \| \| : \| \| \| \| \|{s} \| v \-=--+ +----+
Before processing	Rendered

Point markers

If * is encountered on a line (but not at the end of the
line), it is rendered as a special marker, called the point
marker (this feature is still experimental). See below:

---- \| \| /--* * * \| \| \| ---+ ----*
Before processing	Rendered

Text handling

(This section is still being written)

If the pattern ' o XXXXX' is encountered, where XXXXX is any
text, the 'o' is interpreted and rendered as a bullet point. Note
that there must be a space before the 'o' as well as after it. See
below:

/-----------------\ \| Things to do \| \| cGRE \| \| o Cut the grass \| \| o Buy jam \| \| o Fix car \| \| o Make website \| \-----------------/
Before processing	Rendered

HTML mode

When ditaa is run using the --html option, the input
is an HTML file. The contents of the class="textdiagram"> tags are rendered as diagrams and
saved in the images directory and a new HTML file is
produced with the appropriate tags.

If the id parameter is present in the

tag, its value is used as the filename of the
rendered png. Otherwise a filename of the form
ditaa_diagram_X.png is used, where X is a
number. Similarly, if there is no output filename specified, the
converted html file is named in the form of
xxxx_processed.html, where xxxx is the filename of the
original file.

In this mode, files that exist are not generated again, they
are just skipped. You can force overwrite of the files using the
--overwrite option.

How to install ZXing in Xcode 4

ideame — Sun, 03 Nov 2013 06:45:00 GMT

April 2011
Posted By Yannick Loriot
81 Comments

After an upgrading to Xcode 4, I have been having trouble compiling my own ZXing iOS project. That’s why I decided to explain you how to install easily ZXing with Xcode 4.

First of all (for those who don’t know), ZXing is an open-source library to read the 1D/2D barcodes. This library is available on many platforms such as the iOS, Android, Blackberry, ect. You can find it here: http://code.google.com/p/zxing/.

Before to start, be sure that you have the latest version of ZXing on your computer. If you don’t, you must download it via a SVN client here: http://zxing.googlecode.com/svn/trunk/.

To use ZXing into your project in Xcode 4 follow these steps:

Firstly go to the �?strong>zxing/iphone/ZXingWidget/�?and drag and drop the ZXingWidget.xcodeproj file onto your Xcode “Project navigator�?sidebar. If a dialog appears uncheck the “Copy items�?and verify that the “Reference Type�?is “Relative to Project�?before clicking “Add�?
Now we are going to add ZXingWidget as a dependency of your project to allow Xcode to compile it whenever you compile the main project:
1. First select your project file in the “Project navigator�?
2. Then select the corresponding target.
3. After choose the �?strong>Build Phases�?tab and expand the �?strong>Target Dependencies�?section.
4. Click the �?�?(add) button to display a dialog.
5. To finish add the �?strong>ZXingWidget�?target as shown above.
Now we are going to link the ZXingWidget static library (libZXingWidget.a) to the project:
1. Firstly choose the �?strong>Build Phases�?tab and expand the �?strong>Link Binary With Libraries�?section.
2. Then click the �?�?(add) button to display a dialog.
3. To finish add the �?strong>libZXingWidget.a�?which is located in the “Workspace�?category as shown above.
4. By the way add the following iOS frameworks too:
  - AddressBook
  - AddressBookUI
  - AudioToolbox
  - AVFoundation
  - CoreMedia
  - CoreVideo
  - libiconv.dylib
Then you must configure the header search path of your project to allow Xcode to find the ZXingWidget headers. To do that:
1. In the “Project navigator�?select the main project (not the target).
2. Go to the �?strong>Build Settings�?tab and search the �?strong>Header Search Paths�?
3. Double-click on it and add:
  - The full path of the �?strong>zxing/iphone/ZXingWidget/Classes�?directory. Check the �?strong>recursive path�?
  - The full path of the �?strong>zxing/cpp/core/src/�?directory. Uncheck the �?strong>recursive path�?

Now you just have to import the �?strong>ZXingWidgetController.h�?and the �?strong>QRCodeReader.h�?to your project and use them.
Attention: Make sure that the files in which you are using the ZXing headers have the .mm extension because they use c++ library files.

Voilà! Now all should be ok. I hope it’ll help you!

软�g�U�负载均衡器(LVS/HAProxy/Nginx)的特点和�Ҏ��

ideame — Tue, 16 Jul 2013 07:52:00 GMT

LVS的特�Ҏ��Q?/h2>
抗负载能力强、是工作在网�l?层之上仅作分发之用，没有��量的��生，�q�个特点也决定了它在负蝲均衡软�g里的性能最强的�Q?/li>
配置性比较低�Q�这是一个缺点也是一个优点，因�ؓ没有可太多配�|�的东西�Q�所以�ƈ不需要太多接触，大大减少了�h为出错的几率�Q?/li>
工作�E�_��Q�自�w�有完整的双机热备方案，如LVS+Keepalived和LVS+Heartbeat�Q�不�q�我们在��目实施中用得最多的�q�是LVS/DR+Keepalived�Q?/li>
无流量，保证了均衡器IO的性能不会收到大流量的影响�Q?/li>
应用范围比较�q�，可以�Ҏ��有应用做负蝲均衡�Q?/li>
软�g本��n不支持正则处理，不能做动静分��，�q�个��比较遗憾了�Q�其实现在许多网站在�q�方面都有较强的需求，�q�个是Nginx/HAProxy+Keepalived的优势所在�?/li>
如果是网站应用比较庞大的话，实施LVS/DR+Keepalived��h��比较复杂了�Q�特别后面有Windows Server应用的机器的话，如果实施及配�|�还有维护过�E�就比较复杂了，相对而言�Q�Nginx/HAProxy+Keepalived��q��单多了�?/li>

Nginx的特�Ҏ��Q?/h2>
工作在网�l�的7层之上，可以针对http应用做一些分��的�{�略�Q�比如针对域名、目录结构，它的正则规则比HAProxy更�ؓ强大和灵�z�，�q�也是许多朋友喜�Ƣ它的原因之一�Q?/li>
Nginx对网�l�的依赖非常��，理论上能ping通就��p��q�行负蝲功能�Q�这个也是它的优势所在；
Nginx安装和配�|�比较简单，��试��h��比较方便�Q?/li>
也可以承担高的负载压力且�E�_��Q�一般能支撑��过几万�ơ的�q�发量；
Nginx可以通过端口��到服务器内部的故障�Q�比如根据服务器处理�|�页�q�回的状态码、超时等�{�，�q�且会把�q�回错误的请求重新提交到另一个节点，不过其中�~�点��是不支持url来检��；
N1.ginx仅能支持http和Email�Q�这样就在适用范围上面��很多，�q�个它的弱势�Q?/li>
N1.ginx不仅仅是一�ƾ优�U�的负载均衡器/反向代理软�g�Q�它同时也是功能强大的Web应用服务器。LNMP现在也是非常��行的web架构�Q�大有和以前最��行的LAMP架构分庭抗争之势�Q�在高流量的环境中也有很好的效果�?/li>
Nginx现在作�ؓWeb反向加速缓存越来越成熟了，很多朋友都已在生产环境下投入生��了，而且反映效果不错�Q�速度比传�l�的Squid服务器更快，有兴��的朋友可以考虑用其作�ؓ反向代理加速器�?/li>

HAProxy的特�Ҏ��Q?/h2>
HAProxy是支持虚拟主机的�Q�以前有朋友说这个不支持虚拟��L��Q�我�q�里�Ҏ��更正一下�?/li>
能够补充Nginx的一些缺�Ҏ��如Session的保持，Cookie的引导等工作
支持url��后端的服务器出问题的检��会有很好的帮助�?/li>
它跟LVS一��P��本��n仅仅��只是一�ƾ负载均衡��Y�Ӟ��单纯从效率上来讲HAProxy更会比Nginx有更��的负载均衡速度�Q�在�q�发处理上也是优于Nginx的�?/li>
HAProxy可以对Mysql读进行负载均衡，对后端的MySQL节点�q�行��和负蝲均衡�Q�不�q�在后端的MySQL slaves数量��过10台时性能不如LVS�Q�所以我向大家推荐LVS+Keepalived�?/li>
HAProxy的算法现在也��来��多了，具体有如�?�U�：
roundrobin�Q�表�C�简单的轮询�Q�这个不多说�Q�这个是负蝲均衡基本都具备的�Q?/li>
static-rr�Q�表�C�根据权重，��x��Q?/li>
leastconn�Q�表�C�最��连接者先处理�Q�徏议关注；
source�Q�表�C�根据请求源IP�Q�这个跟Nginx的IP_hash机制�c�M��Q�我们用其作��决session问题的一�U�方法，��x��Q?/li>

rlparam�Q�表�C�根据请求的URl参数'balance urlparam' requires an URL parameter name�Q?/li>
