Covid 19 “Honest Government Ad”

By GarfPosted on Cat General, Journal, SpoofLeave a commentTags , , , , ,
They say "many a true word spoken in jest". This seems particularly applicable to this short video produced by Australia's JuiceMedia... Background to the video JuiceMedia's "Honest Government Ad" started life as satire.  But its probably the most truthful representation where we are right now with COVID-19. This associated video podcast explains its background... Read More ►

Reliable COVID-19 information

The World Health Organization is arguably one of the planet's foremost sources of accurate medical information. I have admired WHO for many years and its site is always worth a visit, even when there isn't a global public health crisis. But its Daily Situation Reports are superb. Lots of information presented in a clear and easily understood manner... https://www.who.int/emergencies/diseases/novel-coronavirus-2019/situation-reports You might also find its main COVID-19 page helpful.

Batch processing in GIMP

By GarfPosted on Cat JournalLeave a commentTags
In my early days of using GNU/Linux full time, we had an application called Gwenview. It was, and still is an excellent thumbnail viewer. But back then it also used to have an excellent set of plugins called KIPI. Sadly the really useful ones such as resizing and changing format completely disappeared when KDE 5 came along. [caption id="" align="aligncenter" width="690"] Screengrab showing BIMP plugin for GIMP.

It also allows sequences of multiple transformations which you can… Read More ►

Safer modelling lights for Chinese flash head units

By GarfPosted on Cat Journal, Photography, Technology1 CommentTags
An interesting question came up a little while back on one of the photography fora to which I belong "I'd be interested in knowing how you swapped the halogen bulbs for led's though waist_it because I have the same problem and as you say those bulbs are hotter than hell, makes using modelling lights with a grid or snoot very fraught?" Well, I had already been down that road in 2015, when I successfully converted all six of my generic Chinese flash heads from halogen to LED modelling bulbs. Firstly, one needs to do a little homework Determine what voltage… Read More ►

BREAKING: Brexit voters to be to pay extra “Brexit Tax” to pay for leaving the EU

By GarfPosted on Cat Journal, SpoofLeave a commentTags
It appeared on the AP this morning and hasn't hit the mainstream news yet, but the EU has just announced that ongoing Brexit negotiations have cost in excess of €1,500,000,000. Brussels has decided that the fairest way to recuperate this money is to tax those who actually voted for it. The current proposal is that Brexit voters will have €100 added to their Council Tax bill. Those who don't pay Council Tax will have it deducted from their benefits. Since the €1,740,000,000 is a little more than needed, it is proposed to spend the remaining €240,000,000 to give overworked politicians… Read More ►

What is a WebP image file, and how do I open one?

By GarfPosted on Cat Journal, Linux, Photography, Technology, WindowsLeave a commentTags
Seems there is quite a lot of buzz about a "new" image format called "WebP"  that is seeing increasing use on-line recently. Although it is attributed to Google, WebP was not strictly a Google invention. It was originally developed by On2 of New York as part of its VP* series "Truemotion" video codecs. Google acquired these technologies when it took over On2. VP8 went on to be the core of Google's WebM video format. WebP is not particularly new either. It was originally released in back in 2010. Whilst the libwebp code library has been freely available under a BSD… Read More ►
Joomla to Wordpress migration graphic

Joomla closedown

By GarfPosted on Cat About GarfNet, FAQ, Journal, Linux, Site Blog2 CommentsTags
As you may have noticed, quite a lot has changed here on Garfnet over the last few weeks. Biggest change of all is the decision to dump Joomla as our main CMS in favour of Wordpress. I will go into more detail about the decision in another post. Suffice it to say that Wordpress is significantly less hassle to maintain than Joomla. And a migration of this sort, on a site this size, is no mean task. So it was not a decision that was made lightly. Anyway we have moved all the content from the old Joomla site and… Read More ►

Welcome to the New Look GarfNet

By GarfPosted on Cat About GarfNet, JournalTags
Welcome to Garfnet. This site is currently undergoing a fairly major re-design and upgrade and some parts currently don't work as well as they should. Sorry about that. I'm working on it as fast as I can. After many years of struggling with Joomla, I finally threw in the proverbial towel and migrated to Wordpress instead. Joomla is a good product. But the migration from one major version of Joomla to the next has proven an absolute nightmare. So, instead of migrating to a new Joomla, this time I decided to migrate to Wordpress instead. I have been using Wordpress… Read More ►

Temporary Shutdown

The business part of Garfnet is already handled by deoss.com It may take some time to move/update all the legacy material here. Some projects may never reappear. However, we intend to reinstate as much as possible. Read More ►

Cheap but effective continuous studio lighting

By GarfPosted on Cat Journal, Photography, TechnologyLeave a commentTags
For continuous lighting, one needs a light source that has good colour balance, uses power efficiently, is reasonably robust and does not present a health or fire risk. I am also a tightwad - interested primarily in "bangs per buck". Whilst I love new technology, I am not prepared to pay silly money for it. Choices Incandescent bulbs are power hungry and get very hot. Hot enough to set fire to soft-boxes or cause serious burn injury to one's models. CFL (compact fluorescent lamp) is better in terms of power efficiency but the big CFL's are flimsy, cumbersome and very… Read More ►

Setting up a home studio

By GarfPosted on Cat FAQ, Journal, PhotographyLeave a commentTags
When we moved home a few years back, one of the most significant parts of our specification was a detached property with enough space for a reasonable sized home studio. We were looking for a place with a rectangular downstairs room, with no internal obstructions, roughly 6.0m x 4.0m, c/w a cloakroom on the same floor with toilet, basin hot+cold water and sufficient room for models to change reasonably comfortably. I based my studio size requirement thus... Absolute minimum 5.0m x 3.0m (Calculation basis: paper rolls are 2.72metres wide; camera needs to be 2-3 metres from model; model needs to… Read More ►

Converting inexpensive LED flood lights for use in the studio.

By GarfPosted on Cat Journal, Photography, Technology1 CommentTags
This is how I converted three left-over cheapie (£60 for a box of ten, delivered) 20 watt daylight LED flood lights for use in the studio. The basic tools you need:- Vernier or digital caliper, M10 ISO metric taps. Suitable spanner (17mm AF). Bench vice. Electrician's screwdriver and wire strippers, to make the electrical connections. Every LED floodlight unit will need:- Suitable socket to fit on standard 16mm studio lighting spigots. M10 ISO metric bolt. Some form of electrical connection or junction box.   Firstly, I found some nice solid aluminium 16mm studio lighting type sockets. These came fitted to… Read More ►

Repairing an elderly Tamron 80-210mm lens

By GarfPosted on Cat Journal, Photography, TechnologyLeave a commentTags
Repairing a Tamron 80-210mm lens. End glass removed using special lens tool, available on eBay for about £10. Inside of the lens was a bit foggy. I suspect that oil/grease had evaporated form the zoom mechanism and had re-condensed on the inside of the glass. Anyway, I carefully dismantled it (which is actually pretty straightforward with the correct tools, cleaned it up with my trusty lens-cleaning solution (33% white vinegar; 33% isopropanol; 34% distilled water), cleaned and lubricated the mech with silicone grease and reassembled it....

Merry Christmas 2014

Lots of hard work going on behind the scenes, but not a great deal to show publicly for all the effort.

Several other new items are also still under way, but sadly not ready in time for Christmas, as we had… Read More ►

Server updates

By GarfPosted on Cat Journal, Site BlogTags
Regular visitors will notice that quite a few Garfnet features are looking a bit tired. And you have probably encountered quite a few 404's too. The reason for this is that Garfnet is undergoing a fairly major overhaul at the moment.Moving to a new, better designed and much faster serverDumping dead or unsupported projectsIncorporating experimental projects - and some nifty toys from deoss.org.The .org part  of DEOSS is being parked-up for a while.
