2018-03-20 - 20:11 by HaraldJoerg in Development
For a long time now, TWiki has been developed in Subversion, also known as SVN. However, since some years I`m using Git for other projects, and it has some features I really would like to use for TWiki as well. For example, in SVN it is pretty inefficient to run several branches in parallel with the monolith that is TWiki core, because in SVN every branch is a complete copy. Git handles this much better. So, all that stands in the way of moving to Git is the migration of the code (easy), the history... more...

Automatic TWiki Deployment

2017-12-06 - 20:11 by HaraldJoerg in Deployment
This year I haven`t done any TWiki development, but I`ve done a bit of testing, bug reporting/hunting/fixing, and taking care of support questions. While doing that, quite often I would have liked to create a fresh TWiki installation with a defined set of properties. These properties are not only what`s written in TWiki`s LocalSite.cfg , but also platform properties: On which operating system and under which Perl version TWiki is running, which versions of which CPAN modules are installed, which... more...

How to: Create a Chat Application with a WebSocket

2016-04-05 - 07:56 by PeterThoeny in Development
WebSockets are a relatively recent addition to the World Wide Web. Sockets are well known in Unix and Linux for many years, used to create endpoints for communication between processes that look like files. The WebSocket specification takes that to the web, defining an API to establish a full duplex communication channel between a web browser and a server over a single TCP connection. Once established, the connection is persistent, which allows for fast communication between a browser and a server... more...

Nested Searches or Hash Searches

2016-03-12 - 20:41 by JaniHamalainen in General
I`m a fairly new user to TWiki and upon encountering a scenario where I needed to do a complicated search I remembered reading about the ability to do nested searches. I implemented the nested search only to find out that it was slower than I expected. It took me awhile to find out there was another option, using hashes as found in SpreadSheetPlugin. Using this approach, my page load time was reduced to about a third when compared to a nested search. The purpose of this blog entry is to... more...

Automate Workflows with If-Then-Actions

2015-04-30 - 04:28 by PeterThoeny in Deployment
TWiki has a new IfThenActionPlugin to automate workflows. Administrators can define if then actions that are triggered when a topic is viewed or saved, an attachment is uploaded, or a user registers. As an example action, every time a topic is viewed, another topic should be viewed in the background, with the purpose to refresh that other topic`s cache. Administrators define if then action rules in a table. The rules have format `if source then target`. The `if` is the trigger (if action), the `source... more...

How Secure is your Passphrase? Generate a Dice-Indexed Passphrase using TWiki

2015-04-20 - 02:59 by PeterThoeny in Development
A passphrase acts as a master password that is used to securely store other passwords. It has to be strong so that it can`t be easily cracked and expose the other passwords. This blog has a dice indexed passphrase generator. The blog also serves as an example of what can be done with TWiki`s SpreadSheetPlugin functions and some HTML.

How to create a print button that opens up a print dialog box

2014-05-16 - 03:57 by PeterThoeny in Development
I was tasked to add a print button to a TWiki application that opens up a print dialog box. This one click option is more user friendly than the standard Print Version File Print option. Searching the internet I discovered that this is possible with some JavaScript. The button could be added directly in topics, but it makes more sense to add it to a header topic that is included by application topics. Example header topic of a knowledge base application: Print this page Title: The sky... more...

How to cache a sidebar for better performance

2013-12-27 - 01:08 by PeterThoeny in Deployment
If your TWiki has a sidebar, top bar or bottom bar that has a lot of dynamic content it can slow down your whole TWiki browsing experience. For example, displaying topic children in a hierarchical tree using TreePlugin can be slow. In this case it can pay off to cache the included sidebar and update it in regular intervals. This is a step by step guide on how to cache the WebLeftBar in the Sandbox web. The same can be applied to any other included topic in any web. 1. Create the cache directory... more...

Advanced TWiki Spreadsheet Formulas: Power and Flexibility - Not For Grandma

2013-03-25 - 04:14 by PeterThoeny in Development
TWiki`s SpreadSheetPlugin just got 9 new functions that add hash capabilities to TWiki. But first some history. Spreadsheets became accessible to the masses in the eighties when Dan Bricklin and Bob Frankston created VisiCalc for the Apple II and later for PCs. They became ubiquitous with Excel; it seems like everybody is using them nowadays, at least to maintain data in tabular form. Spreadsheets were initially developed to automate paper based accounting worksheets. Formulas can be placed in table... more...

How to: Single Sign-on, a Convenient Way to Authenticate Users

2012-06-29 - 06:47 by PeterThoeny in Deployment
Single sign on (SSO) is a way to authenticate users on multiple related, but independent software systems. Once logged in, a user can switch from one system to the next without the need to login again. Conversely, single sign off is a way to log out and terminate access to multiple software systems with a single sign off action. In contrast, a shared authentication scheme that requires the user to log in multiple times using the same identity is not called SSO. An example is a central user directory... more...

What Are Transclusions? How to Use Them in TWiki Applications

2012-05-27 - 18:26 by PeterThoeny in Development
Transclusion is the inclusion of a document or part of a document into another document by reference. For example, press releases have an about section. Rather than copying the about section over and over again, a transclusion embodies a modular design by allowing the about text to be stored only once and included in the press releases. Ted Nelson (who also coined the words `hypertext` and `hypermedia`) introduced the term `transclusion` in his 1982 book, Literary Machines. Parameterization allows... more...

How to Run a Long Background Process in a Web App

2011-09-07 - 05:48 by PeterThoeny in Development
Web applications need to respond quickly to user actions. From a usability point of view, anything that takes longer than a second or two will distract the user from the task at hand. What can be done if a process takes longer, or much longer?

TWiki Has a New Solution for Point & Click TWiki Upgrade

2011-09-06 - 07:07 by PeterThoeny in Deployment
TWiki has a reputation of being difficult to upgrade. The TWikiUpgradeGuide describes how to upgrade TWiki, which is a manual and elaborate process that can take a long time. No more. TWiki has now a point click solution to upgrade a TWiki site with the help of the latest BackupRestorePlugin released on 2011 09 05. The plugin can be installed on older TWiki releases as low as TWiki 2001 09 01 (Athens Release) to easily create a backup that can be restored on a new TWiki release. On restore it is... more...

Wiki Applications and The Long Tail

2011-06-04 - 05:38 by PeterThoeny in Social Business
First, what is Long Tail? From Wikipedia: `The Long Tail refers to the statistical property that a larger share of population rests within the tail of a probability distribution than observed under a `normal` or Gaussian distribution. The Long Tail was popularized by Chris Anderson in an 2004 Wired magazine article, in which he mentioned Amazon.com and Netflix as examples of businesses applying this strategy.` In statistical terms, the horizontal axis of the graph represents a sorted data set... more...

2011-05-28 - 19:53 by PeterThoeny in General
I recently installed TWiki in the cloud, the Amazon Elastic Compute Cloud (EC2). I am sharing my installation experience for all to enjoy.

How to Create Image-less Gauges

2011-05-25 - 05:12 by PeterThoeny in Development
Do you have a need to show gauges in your TWiki or HTML pages? TWiki has a GaugePlugin to show images like or /Plugins/GaugePlugin/tambar1.gif or /Plugins/GaugePlugin/trendup.gif. Those are bitmap images generated on the fly based on some parameters. Showing a page with hundreds of gauges (for example to show server status in a data center) can be slow. This is mainly attributed to the many connections the browser has to make, one for each image download. The latest GauglePlugin released a few days... more...

Web 2.0 Primer: How Does Ajax Work? With Ajax Example

2011-01-07 - 11:24 by PeterThoeny in Development
By now you are very familiar with Ajax: Photos on Facebook load in the background without reloading the whole page, and when you type a word into the Google search box, the search results updates while you type. How does this work? Ajax, which is shorthand for Asynchronous JavaScript and XML, does the magic.

Color: Do you need to pick a color for your web pages? Use the color picker to the left; point and click, then copy the hexadecimal color code to your website or TWiki. The color picker uses the intuitive HSL (hue, saturation, and lightness) color space rather than the more common HSB (hue, saturation, and brightness), which means it`s easy to make a color brighter without touching its saturation, or vice versa. This is a jQuery based widget called Farbtastic, developed by Steven Wittens of Acko... more...

Incredibly, TWiki is now 10 years young! Although I started TWiki in 1998, the oldest TWiki distribution I found is TWiki19990120.zip, e.g. 20 Jan 1999.

Another challenge was that when a new person was hired, that information often did not reach the people who needed it in order to prepare for the new employee`s arrival. There are preparations to be made, such as having their computer configured, having benefits and other company information packets ready for them, and having basic orientation or training ready... more...

Parameterized Includes

2008-06-08 - 23:07 by RichMorin in Usability
I have recently been creating a number of TWiki pages that contain multiple variations on very similar code; e.g., many twisties like this one: where the only difference is the showlink/hidelink text. As a programmer, I don`t like to repeat code. I prefer to write a function, use a macro, or set a variable. (Repeat Yourself). I asked the TWiki Community for suggestions in GenericMacroProcessing and Peter Thoeny suggested ParameterizedIncludes. Parameterized Includes are just the thing! I`ve defined... more...

TWiki Twitters

2008-05-22 - 02:56 by VickiBrown in General
Perhaps you`ve heard of Twitter, the microblogging service that lets you stay in touch with friends, old and new, by web, IM, or SMS. Twitter lets you tell others what you`re doing in 140 character chunks. Recently, TWiki has joined the Twitter crowd. If you`re not quite ready to write a full blog entry you might still have thoughts and comments to share about TWiki. What are you using TWiki for? Have you recently solved a problem? Why not use Twitter? We have two Twitter users: @twikiorg and... more...

Wikis are the glue holding Intranets together

2008-04-24 - 13:20 by Martin Seibert in General
As a knowledge management system and employee portal, a Wiki is of incalculable value within the company network, fueling the Intranet motor. In an Intranet, standard functions and killer applications are effective Standard functions include, for example, employee search, forums, and document management. In addition to these, so called killer applications are spurring on the Intranet. The term was coined by Jakob Nielsen and describes applications that keep the Intranet running and necessary. These... more...

Scalability of TWiki

2008-03-26 - 06:24 by PeterThoeny in General
Sometimes we get the question on how well TWiki can scale. This blog post compiles scalability related information so that you can plan your TWiki deployment effectively. Scaling Across Teams and Departments TWiki was designed as an enterprise wiki from its inception. You find features specifically designed to support large deployments. Other wiki engines have a different focus and may lack some of these features. Wikis typically flourish in grassroots. Once at the radar screen of the CTO/CIO, grassroots... more...

Why there should be a Wiki integrated into every Intranet

2008-03-17 - 12:18 by Martin Seibert in General
Within an Intranet, Wikis are a good means for the quick and uncomplicated collecting of information that is needed for the long term; this creates a base of knowledge as well as a platform for communication that is always available to the participating employees. The following Top Ten reasons are arguments for why every Intranet should have its own Wiki. 1. Slowing of the e mail flood It is true that e mail inboxes function as extensive knowledge storage areas, but they often go unused; in addition... more...

Branch development with SVK

2008-03-11 - 20:30 by GilmarSantosJr in Development
Sometime ago I started TWikiStandAlone project and one of the first problems I faced was `which code base should I use?` Since I would create a branch, I thought about to use 4.1.2, the last stable release at that time, but this approach had some problems: Some changes I needed was already performed at MAIN branch, but not at 4.1.2 When finished, it would be difficult to merge with MAIN On the other hand, if I had created a branch from MAIN, how could I keep it in sync? How could I merge... more...

TWiki Standalone: What is it about?

2008-03-11 - 15:28 by GilmarSantosJr in General
I already wrote a post about TWikiStandAlone project, but after I read the minutes from GeorgetownReleaseMeeting2008x03x03, I realized many people could be thinking `Cool, but what is the benefit for me?` . So I`ll try to answer this question. wink The standard way to run TWiki is as a CGI script. It`s easy to setup and many web servers and hosting services support it. But it`s also slow and resource hungry. There are some hacks and discussions about using things like ModPerl and PersistentPerl (aka... more...

TWiki using IIS and Windows Authentication

2008-03-06 - 15:57 by PhilipSweetenham in General
My use for TWiki is for an installation, on an intranet, where users don`t have to re enter their passwords (or worse still have yet another to remember). I now have a few months` experience of running TWiki using Microsoft`s IIS to handle all issues of user authentication. For brief notes on the installation steps used, please see: Installing TWiki on Windows, using IIS and Cygwin. more...

Requesting customer feedback on removing RCS files in subdirectories feature

2008-03-04 - 07:05 by KennethLavrsen in General
The TWiki development team asks for customer feedback for the following proposal. TWiki has a documented feature that allows the admin to setup TWiki at installation so that the revision control file (the files that ends with ,v) are placed in subdirectories. We have received the first and only bug report that says it does not work. The reason for the feature was to allow twice the number of topics in a web but we are not sure any longer that the feature really gives the needed performance boost... more...

TWiki, YouTube and $2,000

2008-02-28 - 15:48 by MichaelCorbett in General
TWiki is one of the most powerful application wikis around and, with over 2 million users, it is also one of the most widely used. The trouble is, the mainstream media haven`t picked this up yet and so TWiki remains one of the internet`s best kept secrets. YouTube, on the other hand, is in a completely different place. It is the number 2 site on the internet and over 100 million videos get watched every day. Many companies use its high profile to promote their own products and services. We could... more...

Does TWiki need a Foundation?

2007-12-16 - 14:47 by KoenMartens in General
Sparked by the emergence of NET, a new commercial entity delivering enterprise class TWiki services, the debate of a TWiki Foundation has been reopened. NET has TWiki founder Peter Thoeny. Another player in the field of commercial TWiki services that already existed is WikiRing, a brand/partnership founded by some of the most active and long term contributors to TWiki. This begs the question: is TWiki.org able to hold its own as an independent project? If we want to guarantee that the answer to this... more...

Plugins And TWiki 4.2.0

2007-12-10 - 22:11 by KennethLavrsen in Development
The release 4.2.0 is closer than ever. With the RC2 and the very short list of release blockers of which most are documentation and confirmation of fixes things are starting to look very good and a release is very close. TWiki has an impressive number of Plugins. Many are now outdated because a better plugin has been made or the core code has adopted the function. But there are at least 100 maybe close to 200 that will be relevant to many. The TWiki plugin repository is one of the major strengths... more...

How to REST

2007-11-14 - 10:37 by CrawfordCurrie in Development
A Long, Long Time Ago RafaelAlvarez contributed a REST architecture for TWiki that until relatively recently had been largely ignored. That`s a shame, because TWiki has fallen behind the curve on effective interaction, partly because it is so difficult and inefficient to interact with TWiki from Javascript. More recently we have been able to re architect big sections of the core to make REST more useful. Writing a REST script still isn`t all that easy, however. This post is intended to try and make... more...

TWiki Stand Alone Project: Do You Want Flexibility?

2007-10-26 - 20:33 by GilmarSantosJr in Development
I`m a undergraduate computer science student from University of Bahia and I worked with TWiki administration at Science Department and at Brasil. I like TWiki a lot, but I`m a little frustrated with its performance and resource consumption. Many times I had to kill apache (sometimes I had also to reboot server) cause of `out of memory` errors. I started to test alternatives, such as SpeedyCGI and ModPerl. I tried also FastCGI but I didn`t get it to work. Performance raise with ModPerl is fantastic... more...

TWiki uses alot of static files, and util we implement the magic js and css minify we`ve been talking about for a while, you can reduce the load on your apache server, and increase the aparent speed of your user`s experience, by setting the Expires HTTP header for static files to `quite large`.

TWiki Usability Tricks Pt1: Turn your index into a sitemap

2007-09-12 - 16:09 by CarloSchulz in Usability
If you are scanning one of the current indexes (WebTopicList and WebIndex) for a specific topic you have no idea which other topics are related e.g. which topics are child topics. With the help of TreePlugin you can easily turn your index into a sitemap. As you can see in the screenshot all topics are displayed by hierarchy and alphabet. How To: The top level topic in this example is the WebHome (renamed in this example). Therefore the WebHome needs to be the root of all topics in... more...

Block-level 'IF' is quite easy, really

2007-09-01 - 10:18 by CrawfordCurrie in Development
As an experiment, more to see if it was possible or not, I just extended %SECTION to support an `if` type and an ELSE clause. This lets you write something like this: FLUB is defined FLUB is not defined Fun, eh? The syntax is rather clumsy, but it shows how easy it is to add something like this. It`s basically what the IfDefinedPlugin does, if I`m not much mistaken, but with syntax consistent with the rest of the core. The syntax is evaluated after verbatim and literal sections are protected... more...
