Problem Solving Assistance - Problem Steps Recorder One of the first things an IT person will ask you to do when you call in for help is to recreate the problem for them to see. Whether it’s an error message which pops up when Outlook opens or the company intranet not loading properly, it helps if we see what steps happen to create the problem so we can then try to pinpoint the cause.

  • Ubuntu 9 Linux for Human Beings In the midst of the Windows 7 hype, the open source Ubuntu operating system is quietly moving towards the release of version 9.10, Karmic Koala.

  • Snow Leopard OS 10.6 This autumn has seen the release of Microsoft’s Windows 7, Ubuntu Linux 9.10 and Apple’s Mac OS 10.6, aka Snow Leopard.

  • What’s going on when I do without wires? In a personal view by “a data communications person who fell into mobile technology a few years ago and often still wonders why it works (and sometimes doesn’t)”, John Davies attempts to demystify the technical and commercial issues driving radio based network services. L ots of people are using mobile broadband these days. The mobile networks allegedly think it’s free-to-use. Even if you pay for it you don’t pay more for doing more. Even charging networks like losing contact with their dongles only inches away? Why don’t all those 802.11g Wi-Fi users on the their ARPU (average revenue per the coffee shop chains charge by default channel 11 get in each user) birthday!

Both use engineers regard it as a black art so anything that will generate more ideas from anarchic old Aloha but too. Your radio guru understands usage is good for their (financial) mobile broadband is based on what’s going on about as much as bottom line. Some networks, such “souped up” GPRS (General your doctor knows what’s really as 3, are even selling voice over IP Packet Radio Service), invented by happening in your body.

Wi-Fi was but don’t rely on it. In particular, use packet radio techniques and, designed for private office don’t assume it will work in a new like wired LANs (Local Area networks where users were made place, at a different time under Networks such as you probably to act nicely by the local system different interference conditions have in your office), owe their administrator and there was even in different climatic ancestry to Aloha (http://en. “bandwidth to burn”. conditions.

  • mobile Wi-Fi (“Wi-Fi ‘co-op’ could provide internet for all” http:// tinyurl.com/crowcroft08). However, it seems unlikely in the face of opposition from mobile operators who have a vested interest in seeing a substantial return on the 3G licenses (third generation mobile wireless) they over-paid for back in 2000. Many academic environments have long supported free Wi-Fi access, but concerns about network security and congestion is universal. Some projects for general public access have failed on cost grounds or look to have a limited “free lifetime”.

In response to a query on the UKRiders list regarding the downside of wireless networks, Morgan Killick of ESP Projects, Sheffield and Marcus Pennell of SCIP, Brighton made the following points: • Do a Wi-Fi survey of the area using NetStumbler (www.netstumbler.com) or similar because Wi-Fi can be subject to interference/cross-talk from other Wi-Fi transmitters. • Wi-Fi just isn’t as reliable as cabling because the signal tends to fluctuate and may drop out. This makes Wi-Fi unsuitable for networking desktop computers, servers and using data intensive applications like a database. • 802.11g is half duplex (it can’t send and receive data at the same time); 802.11n can but is more expensive. • Wi-Fi signal degenerates through thick brick walls in older buildings and modern pre-stressed concrete in modern buildings. But Wi-Fi access points can be daisy-chained to extend the signal into difficult areas. • Consider the security implications of introducing Wi-Fi. WEP security (Wired Equivalent Privacy) is relatively easy to hack; WPA (Wi-Fi Protected Access) is better than but still not as secure as cable. • Bear in mind that cabled networks are faster and more robust than wireless networks – this makes them better suited networking desktop computers, servers and using data intensive applications like a database. 11
  • Can students contribute to the local ICT support mix? Readers with long memories might recall an article in the Circuit Rider special issue of Computanews 119/120 in August 2002 entitled ICT support in the community sector – the “BrisCIT” vision. In the article, Nick Plant of the University of the West of England described how his students were helping provide ICT support to the voluntary sector in Bristol. In this follow up, Nick brings us up to date on the scheme, and lessons learnt.

  • In summary... or it’s Anne rounded up with a number of key pointers “Planning an ICT project for a volunteer (or indeed anyone!) is key to its success. In the right role volunteers bring an independent view, enthusiasm for the work of an organisation and professional skills that they may otherwise not be able to afford. However, some IT work is best delivered with a Service Level Agreement (SLA) and professional indemnity.” Resources ICT VOLUNTEERING See Anne’s presentation online at www.slideshare.net/ukriders/how- free-is-free-best-practice-for-working- with-it-volunteers Visit iT4C’s website www. it4communities.org.uk for information on their volunteering programme, case studies, • sometimes it’s quicker to pay possible that an organisation examples of opportunities and someone to come in and do it might require a volunteer to their annual IT volunteer awards. than find a volunteer and brief assist with project definition them… even before they get a volunteer in to carry out the Knowledgebase project itself!
