Free twisted storage inc software for linux

Twisted Storage is an application that will take your data and manage it for you, just like a file system. But Twisted Storage goes way beyond what a normal file system does.
What types of "objects" are stored in Twisted Storage : just regular files. The data stored in the system is expected to be fixed content, meaning it doesnt change at all. If you read the data back, change it, and store it, it is considered a different file. There are plenty of examples of fixed content data : emails you received, movies or mp3 files you made or own, documents you wrote, etc. In fact it is estimated that 80% of the data you have on your computer is fixed, reference data.
Your Twisted Storage system can start out small - a single computer with a few disk drives. When you need more storage you can add more disk drives and more computers. But it has been designed to store petabytes worth of data without requiring any special hardware. For example storing a petabyte worth of data, using the biggest disk drives available today (500 GB), would require 2000 disk drives. To overcome the need of special hardware, Twisted Storage is a scalable, distributed system using ordinary commodity computers. Even so that petabyte of data would require 500 computers networked together and that requires special handling.
Twisted Storage has a few features you wont find in any file system. For example once a file is added to the Twisted Storage repository it can be written in multiple locations simultaneously. The system has been designed to be compliant with Sarbanes-Oxley Act: when an object is added to the repository you can no longer delete it and the integrity of the contents are guaranteed. In addition any access to the object is recorded.
Main features:
Scalable to thousands of servers and multiple petabytes of data.
- Regardless of how much data you want to store,Twisted Storage is designed to handle it. The system can grow from one computer and a few disks to hundreds of systems and thousands of disk drivers.
Automatic data recovery without human intervention.
- Twisted Storage doesnt require backup/restore software or procedures. All data written to the system is recorded in multiple locations.
No special disaster recover procedures.
- So long as you have your systems in physically different locations and you have instructed the software to write the multiple copies to those systems, you have no-hassle disaster recover. If one of the sites goes down, the system will retrieve any data from the other systems. Additionally, once the disaster site is up and running, the system will automatically restore the data to the it.
Simplified configuration.
- To ease management of the system, you can change any one systems configuration and have it ripple through out the system.

Twisted Words library provides implementations of a handful of IM protocols, including IRC, MSNP8, OSCAR, TOC, and Jabber.

Twisted Words provides two separate high-level end-user features:

a multiprotocol instant messaging server
a multiprotocol instant messaging client

These are both still in the early stages of development and are not expected to work flawlessly in all configurations, however each is quite usable for a limited set of functionality. A Twisted Words server can be created with just a couple commands:

$ mktap words --irc-port 6667 --pb-port 8787 --passwd password_file --group somegroup
$ twistd -f words.tap

The Twisted Words client is named im and is usable as an IRC client, and possibly an AIM client (depending on the phase of the moon).

Low Level Functionality:

Twisted Words also includes:

Low-level protocol implementations of OSCAR (AIM and ICQ), IRC, MSN, TOC (AIM).
Jabber libraries.

Prototypes of chat server and client frameworks built on top of the protocols.

FileSystemStorage is a project that provides FileSystem storage for Archetypes.

FileSystemStorage is an Archetype storage for storing data on FileSystem This storage is used to avoid ZODB to grow quickly when using a lot of large files.

Storage Inspector is a Firefox extension that makes it easy to view any sqlite database files in the current profile. This includes the anti-phishing and search engine...

Developer Comments:

There are quite a few polish issues that need to be addressed before this version is ready for the masses. If you notice problems, please view the readme.txt file first and tell me if there are other issues.

You can set the storageinspector.openmode pref to 2 if you want the extension to open in a new tab instead of its own window.

I have primarily tested the extension in Firefox 2b1 but would still like feedback on how it runs in 3a1.

If you dont like something, please post here with a constructive statement telling me what you would like.

PicoStorage allows you to store hierarhical information (similar to "files and directories") inside a single file. The functionality offered is largely equivalent to the one offered by any filesystem, or by the Structured Storage and Compound Files.

PicoStorage can efficiently handle huge numbers of small files, with very economical disk usage; it also allows you to keep open (in RAM) simultaneously a large number of files. Transaction support guarantees data integrity.

Learn more about the distinctive advantages of PicoStorage. or look at the benchmark.

The library is available on a dual-license basis: under GPL for free, and under a commercial license for use in closed-source applications.

Using

The library contains the classes File and Dir to represent files and directories. On a File you can read or write a number of bytes from a given offset, and set/get the file size. On a Dir you can create entries (either files or subdirectories), open entries, delete entries, and iterate over the directorys content.

The storage itself (i.e. the whole hierarchical structure, contained in a filesystem file) is represented by the class Storage. Using this class, you can create or open a storage, obtain the root directory of the storage, close the storage and do commit or rollback.

TwistedJava provides an implementation of the Perspective Broker protocol in Java.
TwistedJava is an LGPLed implementation of the Perspective Broker protocol for Java. PB is a remote object protocol, similar to RMI, supporting multiple programming languages.
Included is a policy (Straw) written by Brandon Wiley that lets you use remote Java objects transparently.
You can read the README for the latest version, or read the API javadocs.
Enhancements:
- Adds support for logging in to Twisted 1.1 PB servers.

Twisted Names project is both a domain name server as well as a client resolver library.
Twisted Names comes with an "out of the box" nameserver which can read most BIND-syntax zone files as well as a simple Python-based configuration format.
Twisted Names can act as an authoritative server, perform zone transfers from a master to act as a secondary, act as a caching nameserver, or any combination of these.
Twisted Names client resolver library provides functions to query for all commonly used record types as well as a replacement for the blocking gethostbyname() function provided by the Python stdlib socket module.
Twisted Names is available under the MIT Free Software licence.
Enhancements:
- Errors in the markup used in API documentation have been fixed.
- A bug where the DNS client would sometimes drop a response has been fixed.
- A bug which prevented non-IN lookups from generating malformed queries has been fixed.

A MySQL Storage Engine for AWS S3 project is a plugin storage engine that allows MySQL to access Amazon Web Services Simple Storage Service (AWS S3) buckets and items.
You need a MySQL source tree, and you need to have it built.
Figure out where the source tree is.
In my case its /home/mark/mysql/mysql-5.1-arch
Figure out where the target install tree is.
In my case its /home/mark/mysql/builds/example
Figure out where the MySQL build puts storage engine plugins.
Its probably in lib/mysql under the install tree
Or its /usr/lib/mysql
Or its /usr/local/lib/mysql
For me its /home/mark/mysql/builds/example/lib/mysql
Then run:
./config/bootstrap
./configure --with-mysql=/path/to/mysql-source --libdir=/path/to/mysql-plugins
make && make install
You can optionally copy the "src" directory here into storage/ in the
MySQL server source, rebuild MySQL, and things should compile.
Next, you should probably install the S3 command line tools.
They depend on you having Python.
Get them at http://www.hanzoarchives.com/development-projects/s3-tools/
If you dont have one yet, you need an Amazon AWS account, and then
request that they enable S3. Go to http://amazonaws.com/ to do that.
You will need to get your "AWS Access Key Identifiers".
Assume they are
FV8CY5793BC7CY32YOSN
W9oQxQNJizGgjxNc82giE9/ipefQW19tuO2xpC9G
(I just made those up with a random number generator.)
Put this in your .bashrc file
AWS_ACCESS_KEY_ID=FV8CY5793BC7CY32YOSN
AWS_ACCESS_KEY_SECRET=W9oQxQNJizGgjxNc82giE9/ipefQW19tuO2xpC9G
export AWS_ACCESS_KEY_ID AWS_ACCESS_KEY_SECRET
This isnt used by the storage engine, but it makes using the s3 command
line tools easier.
Use s3mkbucket to create a bucket. Remember that buckets are in a
global namespace, and there are advantages to having them look lik a
domain name. I suggest you snap up "s3.example.com", where
"example.com" is your own domain name.
s3mkbucket s3.example.com
s3put -k solfege/Do -s "a deer, a female deer" s3.example.com
s3put -k solfege/Re -s "a drop of golden sun" s3.example.com
s3put -k solfege/Mi -s "a name I call myself" s3.example.com
s3put -k solfege/Fa -s "a long long way to run" s3.example.com
s3put -k solfege/So -s "a needle pulling thread" s3.example.com
s3put -k solfege/La -s "a note to follow So" s3.example.com
s3put -k solfege/Ti -s "a drink with jam and bread" s3.example.com
Then at the mysql> prompt
create table s3notes (s3id varchar(255) not null primary key, s3val blob)
engine=AWSS3
connection=awss3 s3.example.com FV8CY5793BC7CY32YOSN W9oQxQNJizGgjxNc82giE9/ipefQW19tuO2xpC9G;
select * from s3notes where s3id=solfege/Re;
insert into s3notes (s3id, s3val) values (color/Red, ff 00 00);
select * from s3notes where s3id=color/Red;
delete from s3notes where s3id=color/Red;
You can name the table anything you want, but the fields must be named s3id and s3val, and s3id must be the primary key.
Enhancements:
- More flexible schema, CREATE SERVER, and SELECT without WHERE are supported.
