The Icon Bar is the longest running RISC OS portal. The sensibilities that Acorn instilled in us still influence our interests and writing.
Let us know!

In previous articles, we looked at package managers
and some of the software available on !PackMan
. In this article we are going to highlight some of the software available in !Store and ask for your suggestions.
When you run !Store, it offers you a long list of files and includes both free and commercial software (which you can buy via !Store). As with !Packman it gives you a front end to make it easy to search, provide more details and you can select categories.
If you are looking to run old software on a new machine, our old friend Aemulor is available as free download. There is also in interesting Atari ST emulator called Hatari if you want a real ‘GEM’ environment on your machine.
!Store is also the home for the latest version of !Impression. (although I would criticise the broken link which goes nowhere and looks bad. The pages like PMS Music scribe also include broken links).
Some very high quality software originally written by David Pilling is now freely available and you can find this on !Store.
!Store offers more than software, and you will also find fonts and copies of DraG’N’Drop (which we reviewed here
What are you downloading from !Store?

In a previous article
, we mentioned Git and GitHub. Git
is a version control system which software developers use. Once you have used version control is is very hard to go back. In particular it:-
1. Allows you to have a full, documented history of all changes you have made and roll back to any point.
2. Label your official release versions.
3. See what you have changed easily.
4. Work with other developers (even large groups) in an orderly manner, see who has edited which bit of code, merge code changes together and handle conflicts where several people are editing the same code.
5. Have the security of lots of backups.
6. Never lose anything! (if you use it properly)
Version control solves a lot of complex problems. When I hire new developers, I always ask them about their experiences with Version control systems....
RISC OS itself is available on version control (it uses CVS) and you can explore it online at the ROOL website
Part of the attraction of Git is that it also gives easy access to GitHub (a huge online repository of software source code). And (in theory) it means the source code will never be lost. There are some interesting RISC OS related projects hosted on there. Here is a sample to start your exploration... https://github.com/risc-os-open
converts RISC OS CVS to git. https://github.com/elesar-uk/titanium-build
is the source code for Elesar's Debian Linux build. https://github.com/TimothyEBaldwin/RISC_OS_Dev
Timothy Baldwin's port of RISC OS to run on Linux. https://github.com/dpt/PrivateEye

In a previous article
we looked at !PackMan and !Store. In this article we are going to highlight some of the software available in !PackMan and ask for your suggestions.
When you run !PackMan, it offers you a long list of files (with some nice category and filter options). You can see these in the screenshots below (click on the images for the full sized versions).
When you choose a program it brings up a window with lots of information, including more details, version numbers and dependencies (which it will generally handle for you automatically of tell you of any clashes. Here you can see I am installing the Povray ray tracing program which allows you to design and render 3D scenes.
!PackMan provides a home (and central repository) for many established RISC OS programs and, as a bonus, an easy way to update if new versions are released. !Nettle offers a terminal program for RISC OS, which is still (even in 2017) a very convenient way to access remote systems. You also have OpenSHH as an alternative option. You can also see a whole host of other applications available such as Rsync, FTPc and even other web browsers to try (I would recommend a really fast machine for those).
If you want to indulge in some nostalgia, there is a selection of emulators - upgrade your RISC OS machine to a Spectrum class machine today!
There are some good tools on other platforms which you may miss on RISC OS. My personal favourites of Bash and Grep are available as ports.
!PackMan is not just about software programs. You will find free fonts on to download including these excellent BitStream fonts.
That is a small selection of some of the gems you will find on !PackMan. In a future article, we will have a rummage around !Store. In the meantime, what are your favourite applications or recommendations on !PackMan?

A good crowd braved the Bank Holiday public transport to attend the April ROUGOL
meeting with Chris Gransden talking about porting !Otter and other software to RISC OS.
Before the main event, there were brief 'teasers' for 2 other events.
The ROUGOL organizer (Bryan Hogan), is also helping to organise the Acorn User Show in Cambridge and more details will be appearing in the next few weeks.
Richard Brown (Orpheus
) was also there to announce his new venture RISC OS Developments. This has raised significant funds to do some development and he will be announcing more details at Wakefield on saturday
As !Otter and !QupZilla use QT5, this enabled him to get these browsers to run on RISC OS - he has not had to extensively rewrite and hack the code as the QT5 and UnixLib libraries allow them to run on RISC OS. This also means it is really easy to update as these applications are altered by their developers.
Chris had his overclocked Pi running the software and was able to explain how the !Otter/!QupZilla browsers work on RISC OS. The software is effectively providing a sprite display inside a RISC OS window. RISC OS does not have compositing support (redrawing just the bits it needs) which would speed things up. This is also using shared memory, and memory is high.
Because the software was written for another OS, it is designed to make use of fatures like threads which are not available on RISC OS. This is why performance can be sluggish as RISC OS does not have the capability to offload work onto multiple threads - it is all done by the single, main RISC OS task. RISC OS is also not able to make use of additional hardware acceleration which also speeds things up considerably on Linux.
One of Chris's future hopes it to make use of something like Kronsos on the Pi and have a much faster cusotmised versions for machines which can support it.
The !Otter browser itself is still being debugged and once 1.0 becomes available, Chris will make available a proper RISC OS release. At the moment, it can be a bit complex to setup.
Asked the difference between !QupZilla and !Otter, Chris explained that !QupZilla was currently more stable (less bugs and shared libraries) but Otter would be a better long-term bet.
The !Otter port has come a long way since Chris first started it 2 years ago. It is much faster and more stable although still crashes. It probably is not yet an alternative to browsers on Windows/Linux/Mac but there is not lots of scope to improve further and it opens up a lot of sites to access from RISC OS. We look forward to seeing how it develops, especially once Otter 1.0 officially comes out. Chris has done an amazing job so far! Otter browser main page

In the 'early days' most software had to be 'sourced' from different locations. The only big source of software in one place was Hensa on the University systems if you were lucky enough to have access. You could also connect to Bulletin boards (Arcade BBS
) or get floppy disks through the post from Skyfall or APDL
You can still hunt around (and there are lots of sites with gems we will be looking at in 2017 on IconBar), but in 2017 you have really easy access to huge sources of software straight from your RISC OS desktop. All you need is TWO programs. PlingStore
( ie !Store) gives you access to a range or both free and commercial software (which you can buy with a credit card via the software). All software includes details of the software, website links, screenshots and you can search and explore the software on offer. You will find lots of favourites from David Pilling, R-Comp
, Steve Fryatt, Chris Johnson, Sine Nomine and many others.
PlingStore tracks which versions of the software you have downloaded so it can also offer you the option to get free updates or buy commercial ones. If you are using R-Comp software, they provide a service to update the store with your current purchases to you can use it for updates when they release new versions.
When PlingStore runs, it checks on the Internet to update its information, so it can tell you about new software, updates or special offers. !PackMan
has developed out of RiscPkg. This brought dependency manangement based on Linux solutions to RISC OS (software can now describe what other software it works with and what it needs).
Dependency management is a big problem on many platforms (and trying to fix it on the Java platform has been the big issue for the last 2 releases of Java). Simply, the problem is that you download a new piece of software which needs version 4 of another library. So you install that on your machines. You then find that all your other software stops working as it only runs on version 3.... RedHat came up with a good solution to this problem which RiscPkg uses.
!PackMan builds ontop of this with a slick front end. It also includes a list of software and it knows what other software (dependencies) this software has. So it can ensure you have the software or download it for you as well. As with PlingStore it gives you a wide range of software and it can update its details with new releases when you run it. There is no payment options in !PackMan so all the software is free. !PackMan has some nice features to not only install the software, but add to Apps, run on startup, etc.
Both applications need some discipline to get the most from them. They do not look at your system and spot existing software, and PackMan has a standard location for all software. So you may be better off deleting existing software, and downloading a new copy in the new location through the package manager.
I am also pleased to say that there is little overlap and duplication between the software both offer. In general (apologies for slight over-simplification) PlingStore offers both 'original' commercial and free software from well-known RISC OS companies and developers while PackMan gives you access to the conversions to RISC OS platform from riscos.info and other sites (fonts, !Otter, games, tools, etc) which has grown from Peter Naulls' original Unix Porting Project.
Both applications are free and should be on your machine! !PackManPlingStore

In previous articles, I looked at VirtualRPC as a way to run RISC OS on my Mac. Another options is RPCEmu.
This offers 2 potential main advantages over Virtual Acorn - it is free and it runs RISC OS 5.
The software can be downloaded from http://www.marutan.net/rpcemu/
and you can also get a USB drive with the software on it from RISC OS Open
RPCEmu is available for Mac, Linux and Windows. The Windows and Mac versions both come as ready to run applications while Linux needs you to build the source code (which is also supplied). This is because it needs the Allegro Game Library. This process is not as daunting as it sounds and the instructions are clear and cover each step. If you are already a Linux user, you may already be doing this,. If you are not it is a really good introduction to compiling software which will open lots of new software to you....
The Mac version of RPCEmu has some isses with Retina screens on the later Macs (it works fine if you move it onto an external monitor). You can get around running this by running the software in low resolution (Menu and Info options). This trick does not appear to work on the 2016 October MacBookPros :-(
RPCEmu allows you to configure the software and choose settings like mouse buttons, etc. A copy of RISC OS 5 is included and a Hard drive to setup a basic RISC OS 5 installation.
This gives you a fully-functional RISC OS 5 machine, which can access the local hard drive. I have a shared directory on my setup so I can have a single shared copy of my RISC OS applications between Virtual Acorn and RPCEm. (You cannot share everything because RISC OS 5 and 6 have different setups and !Boot drives but it it useful to be able to shared data and third party software.) In usage I find RPCEmu runs slightly slower than Virtual Acorn but the speed is perfectly acceptable on a high end machine.
So if you are looking for an easy way to run RISC OS on your non-RISC OS machine, or even something to improve your Linux skills, have a look at RPCEmu. RPCEmu website

RISC OS 5.20 released
First seen at the recent Midlands show, RISC OS Open Limited have now officially released RISC OS 5.20 into the world. This stable release of the operating system is available for the Iyonix, ARMini/BeagleBoard, and for the first time for RISC OS 5, RiscPC and A7000/A7000+ IOMD-based machines, including Kinetic RiscPCs. In addition, a stable version of the base hard disc image is now available as well. All users of RISC OS 5.20 are required to at least upgrade to the new version of !Boot as the 5.1x era !Boot will refuse to run on the newer OS.
There are far too many changes for me to attempt to cherry-pick the interesting ones to list here, so to find out what's changed between this release and the last I suggest you check out the change summaries that ROOL link to from their press release above.
This new release can be downloaded free of charge from the ROOL downloads page, or you can purchase physical ROMs (for IOMD machines) or installation CDs (for other machines, or for Kinetic cards with flash ROMs) from the ROOL store. And if you go down the download route, please consider donating to one of the open bounties to help reward ROOL and the RISC OS developers for all their hard work.
The Raspberry Pi and OMAP4 ports are yet to reach "stable" status, so are still only available in the form of (potentially) unstable development builds and (for Raspberry Pi) official beta releases available from the Raspberry Pi Foundation website. In particular, the latest Raspberry Pi release, RC11, has been updated to RISC OS 5.21 and so is roughly equivalent to the stable 5.20 release that's available on other platforms.
Portsmouth show in planning
Not content with just managing the OS source code, ROOL are planning to host a free RISC OS show in Portsmouth, to be held on one of the Saturdays in September (most likely the 21st or 28th). The show is to be free to both visitors and exhibitors, but in order to make it happen ROOL need to know who can turn up and when - so whether you're a visitor or an exhibitor, please get in touch with ROOL and let them know your availability.

Jonathan Duddington, author of the RISC OS e-mail client Pluto, has announced
that as of now, Pluto
is available for free. The project has been open-sourced, enabling other developers to take over maintenance of the software. Jonathan has also updated the program for ARMv7 compatibility, enabling it to run on the most modern hardware.
Pluto is written in C and lets users to manage their e-mails and usenet (newsgroup) subscriptions. It has a fast and consistent user interface with many options for sorting and organising articles, a built in editor for composing e-mails or news postings, and a search facility amongst other features. Thanks to Jonathan for his generosity. The lack of a powerful and free Mail user agent was one of the platform's shortfalls.
Jonathan also announced an update for his eSpeak
text-to-audio speech synthesizer, enabling it to run on modern ARMv7 hardware.
