How to solve “djvu decoder cannot decode djvu files with version >=25” DJVU files opening error

Saturday, February 9th, 2013

If you happen to be running DJVU Solo version 3.1 and you have some documents saved with DJVU Mozilla Firefox browser plugin you might end up with an error:

"djvu decoder cannot decode djvu files with version >=25"

The error is well known and described on djvu solo's website. Though the reason is explained and a work around in future files downloaded via the DJVU browser plugin is suggested. The page doesn't suggest a way on how to open already downloaded .djvu files failing to via DJVU Solo.

Thanksfully there is a fix, get away from DJVU Solo and start using STDUViewer – 🙂

Here is description of STDUViewer taken from their website:

Drawing GANTT Charts and Project Management on Linux, (Microsoft Project substitute for Unix)

Tuesday, October 12th, 2010

I'm studying Project Management, right now. In that spirit of thoughts I and a couple of other guys are building a Project Plan.
As it Project Plan it's necessary to put a GANTT Chart in it to show visually the project timeline (the phases), the duration and the inter-relation between the different tasks which leads the project to an actual completion.

After a bit of thorough research online on available software to deal with project management and particularly, ones that are capable to build a GANTT charts on Linux / BSD.

I've come with the following list of software capable to be a substitute for the Microsoft Project software.
Redmine GANTT Chart

1. Gantt Project
GANTTProject chart GANTTProject Chart

2. Gnome Planner

3. Task Juggler Project Manager with GANTT Capability for (KDE)

4. JxProject – This software is not free, though it can be considered almost free
Take a look also at:
5. Trac , though it doesn't really support GANTT charts it's a lovely software to be used for PM.
Trac Project Management

Another option you have is to try out:
6. PHProjekt

Update 20.09.2016 – PHPProject Old download link is no longer active

It is this link, but the page doesn’t seem to be active any more. I thought you might want to update.

If you are looking for an alternative please check out, it may make a suitable replacement.

Kind Regards,

That piece of softwre really looks promising, especially if we consider that it's web based and how much essential is today to have an anline tools for doing the ordinary desktop jobs.

You can even check an online demo of the PHPProjekt software here

If you're a type of KDE user you definitely has to try out Kplato

As I've tested the software the software is easy to be used, however it still is missing some essential parts that Microsoft Project includes so it's not 100% substitute.
Also it's not able to open Microsoft Project (MPP) files, neither able to save the charts in the .mpp format.

Moving ahead I've came across DotProject DotProject Gantt Chart

I haven't took the time to test it myself but however, as I go through the software website the project looked quite good.
Lastly you can take a look at: 7. PStricks as a mean of project management, however I think it doesn't support GANTT chart building.
