一个类似“more”或“pg”的翻页器,但是它更强大并且其用户界面是中文的。
Cless 是一个 GNU 的 less(版本290)的移植,它可以显示中文 GB(简体)或 Big5(繁体)
语言书写的文件。你可以通过设置环境变量 LESSCHARSET 为 ‘ascii’来切换到通常的 ASCII
文本的读取。
并且,通过设置环境变量 LESSHELP 可以让其帮助文件显示为简体中文、繁体中文或英文。Cless
必须运行在支持中文语言编码的 CXterm 或类似终端模拟器上。

Esmska is a cross-platform application for sending GSM SMS over the Internet.
It uses publicly available web gateways and sends messages through them. This
way it can be much more comfortable than using a web browser or a mobile phone.
Features:
* Send SMS through various gateways (local or international, free or paid)
* Supports all common operating systems (Linux, Windows, Mac OS, etc.)
* Free, under open-source licence GNU AGPL3+
* Import contacts from vCard files or third-party programs (DreamCom)
* Send SMS to multiple recipients at once
* History of sent messages
* Pluggable gateway system - easy to provide support for more gateways
directly by users
* Extensive possibilities of changing appearance
* Many other planned features
As its name suggests, picocom is a minimal dumb-terminal emulation pro-
gram. It is, in principle, very much like minicom(1) , only it's "pico"
instead of "mini"! It was designed to serve as a simple, manual, modem
configuration, testing, and debugging tool. It has also served (quite
well) as a low-tech "terminal-window" to allow operator intervention in
PPP connection scripts (something like the ms-windows "open terminal
window before / after dialing" feature). It could also prove useful in
many other similar tasks.
It often happens that you have non-Roman text data in Unicode, but you
can't display it -- usually because you're trying to show it to a user
via an application that doesn't support Unicode, or because the fonts
you need aren't accessible. You could represent the Unicode characters
as "???????" or "\15BA\15A0\1610...", but that's nearly useless to the
user who actually wants to read what the text says.
What Text::Unidecode provides is a function, unidecode(...) that takes
Unicode data and tries to represent it in US-ASCII characters.
wkhtmltopdf and wkhtmltoimage are powerful utilities to convert HTML to PDF
or an image file using a patched static build of Qt and the webkit rendering
engine.
A webpage can be downloaded directly from the web and rendered into a PDF
document or an image file (multiple formats are supported).
Features of the static version:
* Convert web pages into PDF documents (or images) using webkit
* Adding headers and footers
* TOC generation
* Batch mode conversions
* XServer is not required (however the X11 client libs must be installed)
For proper functionality you may need to install the following port(s):
x11-fonts/webfonts
Emma is a graphical toolkit for MySQL database developers and administrators.
It provides dialogs to create or modify MySQL databases, tables and
associated indexes. It has a built-in syntax highlighting SQL editor with
table- and fieldname tab-completion and automatic SQL statement formatting.
The results of an executed query are displayed in a resultset where the record-
data can be edited by the user, if the SQL statement allows for it. The SQL
editor and resultset-view are grouped in tabs. Results can be exported to CSV
files. Multiple simultaneously opened MySQL connections are possible.
An open-source, distributed, time series database with no external
dependencies. InfluxDB is the new home for all of your metrics,
events, and analytics.
InfluxDB is a time series, metrics, and analytics database. It'written
in Go and has no external dependencies. That means once you install
it there's nothing else to manage (like Redis, ZooKeeper, HBase,
or whatever).
InfluxDB is targeted at use cases for DevOps, metrics, sensor data,
and real-time analytics. It arose from our need for a database like
this on more than a few previous products we' built. You can read
more about our jurney from SaaS application to open source time
series database.
buzhug is a fast, pure-Python database engine, using a syntax that Python
programmers should find very intuitive.
The data is stored and accessed on disk (it is not an in-memory database);
the implementation has been designed to make all operations, and especially
selection, as fast as possible with an interpreted language.
The database is implemented as a Python iterator, yielding objects whose
attributes are the fields defined when the base is created ; therefore,
requests can be expressed as list comprehensions or generator expressions,
instead of SQL queries.
Cassandra is a highly scalable, eventually consistent, distributed,
structured key-value store. Cassandra brings together the distributed
systems technologies from Dynamo and the data model from Google's
BigTable. Like Dynamo, Cassandra is eventually consistent. Like
BigTable, Cassandra provides a ColumnFamily-based data model richer
than typical key/value systems.
Cassandra was open sourced by Facebook in 2008, where it was designed
by one of the authors of Amazon's Dynamo. In a lot of ways you can
think of Cassandra as Dynamo 2.0. Cassandra is in production use at
Facebook but is still under heavy development.
This module is useful if you manage data which has a lot of on/off attributes
like active, inactive, deleted, important, etc. If you do not want to add an
extra column for each of those attributes you can easily specify them in one
integer column.
A bit field is a way to store multiple bit values on one integer field.
The main benefit from this module is that you can add additional attributes
to your result class whithout the need to deploy or change the schema on the
data base.
