Our Next Meeting: Wednesday 18th October 2013
Raspberry Pi. Linux and RISCOS evening- All.

This promises to be quite a good hands-on evening. John is bringing his LaPi machine and will talk about some of the problems which are still not resolved, but he is expecting to get them resolved at the London RISC OS show on Saturday week. He may also show it running Linux as an alternative to RISC OS.

Please bring along anything you think may be of interest.

4. Chairman's Report

5. Treasurer's Report

6. Election of Officers and Committee

7. AOB.

The following is a brief summary of the main points to the AGM a more formal report will be available later.

Present: Gareth, Michael, Paul, Duncan and Peter.

Apologies for absence: Anne had emailed that she would have liked to be at the meeting but felt unwell on the day. She sent her best wishes to the Club.

The minutes of the previous AGM were presented and read in silence.

Matters arising: The paper copies however had unfortunately omitted a line regarding EAUG liaison. The emailed copies were correct.

The visitor fee on the website should be shown as no charge and this was still outstanding.

Peter said that we still did not have up-to-date accounts and had lost contact with Andy who had been ill during the year.

The previous minutes were approved proposed by Gareth seconded by Paul. They will be signed with the above corrections completed.

Chairman's Report

Despite what has been a challenging year for the Club in some respects we have continued to present a varied programme of topics that I hope you have all found enjoyable. I myself have struggled at times to give as many hours as I once did to prepare talks due to my now longer commute into London, but if anything I think we have seen more variety over the last year and more members bringing along interesting hardware and problems for us to look at and work with.

Following our last AGM in May 2012 we were introduced by Peter to the world of USB microscopes. Not in this case a hugely expensive piece of equipment from a lab, but a relatively low cost device from Maplin that nevertheless had some impressive magnification.

June saw us host a PC Tips and Tricks evening, although sadly due to our numbers and holiday season being upon us this was by far our quietest event.

In July we hosted an evening on scanning featuring a range of scanners. In particular this highlighted the VueScan software which can be very useful on Windows/Mac and Linux for getting older scanners to work when up to date mainstream drivers may not be available.

August was our first social event of the year held at the Brantham Bull for an enjoyable evening, perhaps not with the fastest service.

For September we revisited Linux for an update from Gareth on his use of Ubuntu and RedHat as Virtual Machines on his Mac.

In October we also returned to the Mac to see the latest release of Mac OS X - Mountain Lion which started to integrate some of the features developed for phones and tablets back into a mainstream desktop OS.

Continuing a theme in November Michael gave us a detailed overview of the release version of Windows 8, showing off the new Metro interface and touchscreen interaction together with the mostly familiar Windows desktop, now lacking a start button.

December as is the norm was our gadgets and party evening with a whole host of gadgets and devices together with some tasty seasonal fare.

January 2013 saw us return again to the Brantham Bull where Royal was able to join us with his carers. I myself made a valiant effort to escape London on the commute from my new job while trying not to hold up proceedings. Putting technology to good use I was able to message ahead my order to Peter.

In February we took a look at Cloud Computing and what it has to offer business large and small who require servers but do not wish to run a data centre.

March saw us take a look at RPCEmu which gains more and more traction for free emulation of RISCOS hardware on Windows, Mac and Linux and now of course running RISC OS 5.x from ROOL.

April was our Slideshow evening for the year and feature pictures from Canada, South Africa, the Isles of Scilly and John's travels to the Floriad flower festival in Holland.

In May we took a closer look at tablet computers which have become very popular in recent years with both Peter and Paul showing off their Android tablets and the uses they have found for them. Peter in particular using his for distance measuring connected to Bluetooth to a device from Leica.

June and July were both impromptu evenings on our computer issues. In June Duncan spoke at length about his issues with his slide scanner in Linux, eventually solved with VueScan and also of his experiences scanning in old slides and negatives from a variety of film formats. These led to him creating his own film/slide holders for some of the more obscure formats to use in his 35mm scanner. In July John Rye was able to demonstrate to us his RISCOS laptop "LaPi" which cleverly combines a Motorola Atrix Lapdock with a Raspberry Pi in a small external case all powered from the dock's battery.

And finally in August we had a social evening at the Boathouse Restaurant in Dedham which was a pleasant evening in lovely surroundings.

Despite our very small numbers now I believe we have put on a good show of talks over the the last year despite us all having busy lives, and this is something we can hopefully continue into the future.

As ever if anyone feels they could support us on the Committee please do speak up, and likewise if you would like to present a talk or indeed suggest a talk we could perhaps research and hold for you later in the year.

My thanks go to Peter for organising 3 enjoyable social evenings, and to all of you for continuing to support the club.



Treasurer's Report

Since our current Treasurer was unavailable Peter said that he was trying to put together some accounts from various bank statements. The current bank balance was £375.35 with about £117.50 owed to Peter giving balance of 257·85. We still needed to pay rent for this evening and next month.

Peter said he had managed at last to change the bank account and have Frank's details removed so that Anne would no longer be embarrassed by receiving bank letters. We still needed to approach the bank to get the officers' validated and added as signatories. Andy does not appear to be able to act as Treasurer any more due to ill health and family commitments.

Election of Officers:

In the absence of Andy it was decided to change some of our roles and the Committee is now

Position Name
Chairman: Gareth
Secretary : Peter
Treasurer: Michael
Vice Chairman: Duncan
Committee Member: Paul

It was also agreed to sort out the bank accounts signatories as soon as possible and to waive the membership fee for this year.


Following our AGM Gareth gave an overview of the forthcoming

update to Mac OS X 10.9 codenamed Mavericks.

OSX 10·9 Mavericks by Gareth

Mavericks is scheduled for release this "Fall" and a Developer Preview is currently available to registered developers. Sadly Gareth does not have access to the developer images so the evening was based on the available marketing and public documentation together with a number of video demonstrations from YouTube.

OS X typically releases every 12 - 18 months and updates tend to bring incremental rather than major updates to the end user with a low cost to encourage upgrading. Mavericks is no exception to this as Apple continues to integrate features from iOS and the iPhone and iPad back into the Desktop. Under the hood there are some significant changes though which should see beneficial increase in battery life for instance.

The headline applications to migrate from the portable devices to the desktop in Mavericks are iBooks and Maps, bringing both the large library of electronic books and the mapping service available as native applications.

Web browsers can often be a battery killer, with Flash and JavaScript hogging CPU even in the windows and tabs not actively being viewed. Safari in Mavericks aims to alleviate this as far as possible by intelligently throttling back or suspending inactive tabs and suspending plugins that are not actively being viewed.

Mavericks supports wireless display using an Apple TV either as a mirrored screen or as an extended desktop over Wi-Fi. The multiple monitor support in general has now been improved such that a full screen only application can utilise one display with conventional desktop apps on the other, or indeed 2 full screen only apps utilising both screens.

The Finder now supports tabs enabling you to have multiple file system tabs open rather than multiple windows, a long requested feature and files can now be tagged for more enhanced searching and short listing.

The Server edition can now act as a central XCode server for software development, and has integrated support for cacheing application downloads from the App Store.

Under the hood there are a number of updates aiming to improve battery life for portables. "App Nap" seamlessly monitors each running application and adjusts CPU, disk and network priority to reduce power and optimise performance. Background applications may be slowed or even suspended with priority being transferred to the foreground app. App Nap monitors whether an application has windows visible, whether it is playing audio or transferring data and uses these to optimise.

In parallel with App Nap, Mavericks introduces a feature called Timer Coalescing. This feature attempts to coordinate the resource demands from running applications and background tasks to avoid unnecessarily waking up hardware resources. CPU and other hardware resources need to stay in sleep state as much as possible to optimise power and battery usage, timer coalescing groups together interrupts that would wake the hardware reducing the number of state transitions and hopefully extending battery life.

To improve the performance of the system under heavy load Mavericks introduces compressed memory. As memory run lows and to avoid excessive use of slow swap space on disk the system enables compression of the data in memory to free up resource much more quickly that swapping to external storage.

For "one more thing" Gareth also brought along a Nexus 7 tablet designed for Android running a developer image of Ubuntu Touch which is currently being developed for phones and tablets. Development continues apace but an initial stable release should be available with the launch of Ubuntu 13.10 later in October.


I'm just glad we ave been able to hold our AGM and look forward to some interesting talks in future.

Our Website and Email

Our website has had to be moved since BT is no longer giving free hosting to customers and Peter was running the old website on his account. So Gareth has been fortunate to register a web address of our own and has generously hosted it on his own woolridge domain. All our old website data has been ported to the new site and a redirection placed on the old address. The old site will disappear some time soon

If anyone would like a copy of the CD of our old newsletters this could be arranged.

I am open to suggestions on what people would like to have included in the website.
