| Public Open Source Training Courses running this summer and autumn in Melksham We've got a continuing series of Open Source courses scheduled through the summer ... as I write (late April) we still have availability on all public courses, although in one or two cases our rooms at Well House Manor are all spoken for. Python - 2 courses, each every 2 months - one for newcomers to programming and the other for people who have programmed before in other languages. We're talking Python 2.6, but with strong coverage now of Python 3.1. [link] Perl - 3 different courses - one to teach you Perl, and the other two more advanced, covering OO and Web use. Still at Perl 5, but plenty of talk of Perl 6. [link] PHP - No fewer than five courses! We'll teach you whether or not you've programmed before, and we have special weekend courses which are tuned for the leisure / hobby market too. And the more advanced courses cover not only the language, but also the application of PHP to make really effective web sites. All courses are PHP5 based, with consideration of PHP6 ...-> [article continues] (Written 2010-04-27) |

The word global is used in declaring variables in some languages such as Tcl and Python to indicate that the variable being referred to is shared with the variable of the same name at the top scope. To use the word global, which implies that the declaration makes the variable visible everywhere, is misleading The word enable is used in places such as the Apache http server build process to request that a facility is included within the build. But it does not mean that the facility is actually switched on and usable when the build has been done - other quite separate configuration work is needed to truly enable it! I have some sympathy with the people who have to come up with words to describe what these words actually do - I'm not sure if I would have done any better; I do know that I have to be very careful when explaining "Global" and "Enable" on our courses.

Faster network, but not faster browsing until ... We switched up to the 50 Mbyte Virgin Cable service a few weeks back - looking for still faster internet connection. Most of the time, our traffic levels don't need such a high speed link, but we've two dedicated servers (housed in England and Germany) and we need to take incremental and occasionally full backups - and at such times the service provides a seriously shorter transfer. It's also good for faster upload at the times we're viewing webcams over the link. But, curiously, browsing speeds hadn't improved. A distinct pause from page to page, and a message at the base of the browser "looking up www.google.com" or some other domain name gave us the clue ... the DNS servers that we've been using appear to have been overloaded, or are perhaps being used to throttle back traffic. Chris pointed me in the direction of Google's public DNS service, with a DNS server at 8.8.8.8 and another at 8.8.4.4 - see [here] for details - and a switch to using those machines gave an immediate obvious improvement. I've switched a couple of our systems to use the Google service, and I'm going to watch how it goes. And perhaps we should set up a local DNS server at the hotel and at HQ to cache address lookups. We will see some other differences ... a mistyped domain name that points to something that's not registered has been leading to a Virgin Media search results page; now it leads in many circumstances to Google's best guess. So there's another positive outcome. Part of me worries that Google is becoming a bit of a monopoly, but they're providing a technically excellent product once again. (Written 2009-12-14) |

Changing Images  The simplest ideas are often the best ... and the simple idea of having a picture that automatically changes from time to time on your web page helps keep your customer's interest up when he returns to your site. You're seeing a picture of our dog Gypsy to the right of this block of text, but I don't know exactly which one ...On yesterday's PHP course, I wrote an example that selects the picture that is displayed based on the number of minutes that have elapsed into the hour - you can run that page [here] and you can see the source code [here]. It's an easy step to change the "number of minutes" into a "number of hours" into the day, and produce a page that shows a different image depending on the time of day - a nighttime shot until 7 a.m., then a breakfast, followed by ... well, you'll be getting the idea. A further request that your customers may make is for changed character sizes, backgrounds, etc - and if you provide a "service" you've a legal requirement in the UK to take all reasonable steps to ensure your service is accessible to the disabled, which means (on a web site) that you should provide this flexibility, no ...-> [article continues] (Written 2009-12-17) |

A little more about this newsletter ... At Well House Consultants, we run niche IT training courses ... and we run a hotel for delegates on those courses and other visitors to Melksham too. And we make a lot of friends - have a lot of ambassadors with whom we want to keep in touch. So every day Graham (that's me, writing this piece) puts together an article or two which might include the latest sample programs that I've written during the current course, new information about Well House Manor - our business hotel, tips on search engine optimisation, announcements of upcoming public courses, pictures of local places, and even (on occasions) rants and whimsical pieces to keep those friends up to date and in touch. The feeds are available directlt via the Blog - "The Horse's Mouth", they're on our Twitter Feed and you can find me at my LinkedIn profile. But most people just want to look us up occasionally - every month or two, and then to catch up on the latest news just for their particular subjects of interest ... and that's what this newsletter is about You'll find above the titles of ALL the new articles written in the last two months, listed by major subject area, and showing as (new) with their date of publication. You'll find additional articles in each category too - topping each category up to a minimum of five articles. And you'll find a link at the end of each section which lets you expand that section to show the titles of every article that's been published in that section. After all, "the old ones are often the best ones", aren't they? go to Top or other editions | |
