Here's a quick roundup of everything that's happened over the past few weeks.

New software releases

NetSurf 2.8

Version 2.8 of the NetSurf browser was released last month. The major new features in this release are a new cross-platform system for handling frames and iframes, and an improved image cache.

Charm 2.4

Peter Nowosad's Charm programming language also saw a new release last month. Version 2.4 is the first version of the language to be 32bit compatible, so if you're looking for something a little bit different from your programming languages then now's a good as time as any to give it a go.

StrongHelp 2.86

A new version of StrongHelp was released to the StrongED mailing list, featuring several bugfixes, mainly for ARMv7 compatability. Download it here.

CDFaker now 32bit

Steffen Huber has released a 32bit version of Andy Armstrong's CDFaker utility, which allows you to mount ISO images and read their contents via CDFS. Apart from being 32bit compatible, this release is also fully ARMv7 compatible.

InterGIF 6.18

Martin Weurthner's popular InterGIF utility has also seen an update. The main focus of this release was to make the utility ARMv7 compatible.

DigitalCD updates

Music player DigitalCD and related modules (TimPlayer, DiskSample) have been updated to add support for more tracker music formats, along with a few bugfixes.

New C/C++ tools release

And last but not least, RISC OS Open have released version 22 of the C tools package. The main development focus for this release was on improving objasm, to add support for the full ARMv7 instruction set, and to add support for some features offered by the assembler available in ARM's RealView package (which has a shared heritage with objasm and the other 'ROOL' tools).

RISC OS 5 news

OMAP4 ROM now available to download

As mentioned in the previous news roundup, Willi Theiss has been working on porting RISC OS to TI's OMAP4. This work has now found its way into ROOL's CVS, allowing them to add a (Pandaboard-compatible) OMAP4 ROM image to the downloads page. However as this is a first release, expect to see a fair number of bugs and missing features.

Raspberry Pi port on the cards

Veteran developer Adrian Lees has expressed an interest in porting RISC OS to the low-cost Raspberry Pi computer. Previously the possibility of a port was put into doubt by the question of whether anyone would have access to the required hardware documentation, but since Adrian works at Broadcom alongside Raspberry Pi Foundation members it sounds like lack of documentation will be the least of his issues.

Bounty pot reaches £1K

The amount of money available to developers through the ROOL bounty system has now reached £1000. However none of the bounties have yet hit their (secret) target values, so it looks like any budding programmers will have to wait a bit longer before they're able to take on any of the tasks listed (unless they want to do it for free!)
 
Correction: As has been pointed out by ROOL, bounties don't have any target funding values. Instead, interested parties merely need to get in touch and say that they're starting work once they feel that the money in the pot has reached an acceptable value. For more info on the workings of the bounty system, see here.

Filesystem bounties

On the subject of bounties, developer Rob Sprowson has recently had a go at analysing all the different filesystem wishlist items and boiling them down to a list of defined bounties, which can be found here. It's probable that this list (or something close to it) will be adopted by ROOL and added to the bounty area of their website in the near future. Not to be content with just making a bounty list, Rob has also had a go at fixing a few filing system bugs recently, mainly focusing around making sure FileSwitch and the filer are happy with files between 2G and 4G in size, as well as fixing a couple of bugs in RPCEmu that stopped large files from working there.

London show approaching

And finally, this is your official reminder that the 2011 RISC OS London show is here in just under two weeks time, on the 29th of October. Apart from the usual names on the exhibitors list it's worth pointing out that there'll be a pre-release version of the Raspberry Pi board on show. And if Adrian hasn't got it running RISC OS natively by the end of the show, it sounds like the RPCEmu team will be there with a copy of the RPCEmu emulator as a fallback. Unfortunately one notable absentee from the exhibitors list is RISCOS Ltd, who are unable to attend due to a clash with another commitment.
 

It's about time we had another one of these, isn't it? As you've probably guessed, this time I'm looking at Burn 'Out, an arcade-style racing game released by Oregan in 1995, and rather heavily influenced by the arcade classic Power Drift.
 
 

André Timmermans, author of DigitalCD, has released an update to his tracker music playing module TimPlayer. The new version adds support for several new tracker file formats, as well as including many other changes and fixes.

Meanwhile, RISC OS Open have secured permission to release the SharedSound module. This should improve the situation regarding sound support for owners of modern ARMv7 powered RISC OS systems.

 

Here's a quick round up of all the interesting things that have happened over the past few months that we didn't find the time to report on.

ROOL bounty scheme

ROOL officially announced their bounty scheme, and then followed up that announcement by beginning a process of doubling-up the first £1000 worth of bounty payments - for every pound you contribute towards a bounty (except the ROOL admin bounty), ROOL will also contribute a pound.
 
Although none of the bounties are yet to reach their (hidden) donation targets, it's worth noting that the biggest bounty so far has over £300 allocated to it. So although the bounties aren't likely to come close to the average hourly wage of a professional programmer, they're certainly not going to go for chump change either.

And also

Jim Lesurf has announced that he is offering a £300 bounty prize to the first person to add USB audio support to RISC OS.

BBC Domesday site

No more hunting down rare laserdisc players - the BBC have launched a new section of their website containing the content of the 1986 Domesday system.

Show videos

Proving that online videos of Acorn shows aren't just a modern thing, Mike Cook has pointed us towards this video he uploaded of the 1985 Micro User show. Ah, the memories.

More news sites emerge

In what's possibly an attempt to plug the gap left by our lack of updates, several new news sites have sprung up:

• Vince "One C or two" Hudd has turned RISCOSitory into a news site, which he looks to be updating on a fairly regular basis.
• For those who despise reading and just want a list of links, Martin Hansen has just the thing for you - he's added a section to the RISCOScode website that he's using for quickly linking to newsworthy things.
• And then there's the newest contender, riscos.blog.com, which seems to be updating at a faster rate than RISCOSitory but with shorter articles as a result.

GCC 4.1.2 crawls closer to release

With the first prerelease being over a year ago, you'd be forgiven for thinking that we'd all be using GCC 4.1.2 by now. But to prove that good things come to those who wait, it was only in April of this year that work began on the release preperations. The GCC team are still no doubt after your feedback, so if you're maintaining a RISC OS program that relies on GCC, please have a go with the latest version and report your findings.

RISC OS 5 development

Apart from the bounty announcement, plenty of other things have been happening with RISC OS 5 recently:

• Tom Walker has sneakily sneaked some sources into ROOL's CVS: A S3C2440 HAL and a S3C6410 HAL, targeting the Mini2440 and Mini6410 respectively. Although the ports are very rough around the edges, what's interesting is that (a) the S3C2440 is the same SoC as used in the A9home, and (b) the S3C6410 is the first ARMv6 device to natively run RISC OS.
• Not to be out-sneaked, Willi Theiss has recently announced that he's been working on a port of RISC OS to the PandaBoard, a development board closely related to the BeagleBoard but with a cutting-edge dual-core Cortex A9 processor instead of the BeagleBoard's ageing Cortex A8. Although the port is currently only using one core, early benchmark results suggest that the out-of-order execution and improved VFP hardware are enough to deliver a significant performance boost over current hardware.
• TBA software have been keeping themselves busy by releasing a test version of an updated BBC BASIC with VFP/NEON assembler support.
• Chris Wraight has released test version of his revamped Calc/SciCalc application.
• Rik Griffin has also been hard at work on an improved Filer_Action module.
• And finally the IOMD (i.e. RiscPC) version of RISC OS 5 has also seen a few improvements recently, making it much more usable on real hardware (although there's still plenty left to be done)

 

What is Unicode?
 
Unicode has been developed as a standard way of representing the characters in all the world’s basic languages.
 
It was designed to make it easier to exchange files, between computer users who write using different alphabets, and to make documents that do not use the Western, Latin alphabet, readable all over the world, regardless of which program, or operating system is used to view them with.
 
Before Unicode was introduced, people used standard eight bit (one byte) fonts, which allowed the representation of only 256 different characters. When creating complex documents which included, for example, special symbols and foreign-language characters, you would have to use several different fonts to get all the required characters.
 
The problems would start when you emailed this to somebody else, and they didn’t have the same fonts installed on their system, that you had used to create it with. Parts of the document would be unreadable.
 
A further problem arises when two different encodings are used for the same set of characters.
 
For instance, Cyrillic web pages are often encoded in either KO18-R, or Windows 1251, which both have the same characters, but in different positions in the font table. If you sent a KO18-R document, or email, to somebody whose system was set up for Win 1251, they might not be able to read it.
 
Unicode was designed to get around these problems by using more than eight bits to represent a character. By using more than one byte, virtually every symbol, or character that exists in any language, can be allocated its own, unique number (or code point), so that the character can be represented by the same number, whatever operating system, or program you are using anywhere in the world.
 
If your system supports Unicode, a word processor or web browser that loads a Unicode document, will check all the code points in the document against a look up table, which tells it whether that character is defined in any of its installed fonts. If so, it retrieves the character’s details, and renders it to the screen.
 
Unicode makes the sharing of documents and web pages, across national boundaries, much easier, and is a God-send to those who regularly communicate with people who don’t use our alphabet, or are interested in studying foreign languages.
 
So how does RISC OS bear up to the challenge of supporting this international standard ?
 
 

Last month Alan Peters surprised everyone by announcing that TBA Software are back from the dead. Their back catalogue includes AXIS (which was awarded five stars by Acorn 32-Bit Gaming), Formula Two Thousand (FTT), Cyber Ape, Cobalt Seed, and BHP [Review].

TBA Software are sharing their progress on a new blog. Already they have released a 32-bit only version of their high performance image filing system, TBAFS.

They have started to produce a 32-bit version of their 3D graphics library and game runtime, TAG, and they are working on using extra features of modern ARMv7 CPUs to make it run even faster.

Another member of the TBA Software team, Martin Piper [Interview], has managed to render levels from BHP on Windows. Alan is hoping to get BHP running on the BeagleBoard XM in the near future.

In other news, the excellent RISC OS classic Inferno [Review] has been released for Apple iOS devices. There's no mention of support for Android devices. Paradise's website claims that Inferno is their "very first iPhone title", so perhaps we will see Overload [Review] and the long awaited Pocket Money / Toybox Dreams [Preview] make their way over to modern handheld devices too.

 

It's that time of year again - this Saturday marks the date of the sixteenth Wakefield show. The show will take place at its usual location of the Cedar Court Hotel, and will run from 10:00am to 4:30pm. Entry is set to cost £5 per adult, which grants you access to both the main show floor itself and to the theatre presentations. Highlights of this year's show look to be:

• R-Comp/RCI - Apart from the other wares they'll be bringing to the show, expect them to also take the opportunity to officially launch their new ARMini computer.
• RISC OS Open and RISCOS Ltd - Providing you with the latest OS updates, no matter which side of the fence you're on.
• Mike Cook's Gadgets stand - If you've ever wanted to find out what he's been up to since his Micro User/Acorn User days, now's your chance!
• WikiProject RISC OS - Meet the people who aim to put RISC OS back on the map (on Wikipedia, at least).
• Also look out for lots of new software releases, including (but not limited to) new versions of Organizer 2 and Impact.
