Firefox 57 (Quantum) is missing a font from it’s newtab page and from fonts from other pages fail to display; here’s a quick fix. Update: turns out to be a sandboxing issue (see end).
Firefox 57 Quantum
If you’ve just installed Firefox 57 like me (on Kubuntu 17.04) you may be a little disoriented – it’s different.
font display error in Firefox 57
For me it was a little too different the about:newtab page, set as my start page (see image), lacks a font it’s instructed to use. Here’s how to work around that.
Which font is missing?
So, I’d just updated to Firefox 57 and assumed that maybe it wasn’t finding one of my fonts for some reason. Using the developer tools we can see the font SegoeUI is missing: Read the rest of this entry »
Perfume might work but DEET or Lemon repellants work better.
Overall, the results from this study confirm that DEET repellents are the most effective mosquito repellents in the market. Although, based on the results from this study, a lemon-eucalyptus oil containing p-menthane-3,8-diol has similar efficacy compared with DEET repellents.But DEET and Lemon based products are best.

iscan for linux can’t find my printer (originally published 2014-02-11, updated 2017-01-02)
Epson’s iscan scanner app
Fixing the config files
It’s been a couple of years now that I’ve had iscan installed. Today I wanted to do some high-resolution scanning so I thought I’d try and get it to work as I imagine it might be the best tool to interface between my Kubuntu 13.10 GNU/Linux distro install and my Epson Stylus SX535WD [update: still using same printer-scanner-copier with Kubuntu 16.04, this method still working]. That W in the model number shows I have a wireless connectable Epson. Over wifi I have no problem printing or scanning using the default tools and with the “epkowa” drivers from Epson but attempting to use iscan (“Image Scan! for Linux”) would give an error:
“Could not send command to scanner. Check the scanner’s status.”
In essence I did “sudo nano /etc/sane.d/dll.conf” and made the file there read:
# /etc/sane.d/dll.conf – Configuration file for the SANE dynamic backend loader
with no other (uncommented) entries. Previously it had an epson2 entry which I think may have been confusing things.
Then I made sure that the /etc/sane.d/epkowa.conf file new where on the network to find my printer. I gave the printer a fixed IP when I installed it, X.X.X.10 [use the proper network address for your printer, not this placeholder]. Read the rest of this entry »

The most likely maths behind the alleged petrol-pump price scam being reported on Facebook.
I don’t normally share this kinda thing …
Unless there’s bad maths involved!?
On Facebook usually if a post starts “Ok so I’m not normally one to share things like this but…” then it’s down to some marketing genius trying to dole out product links cloaked as hot tips. So, when I saw this post I assumed that it was something along those lines. Instead (at first look at least) it appears to be a report of over-charging for petrol:
“Now I heard about garages starting to clock the pumps to charge you more than advertised so I started putting the test to the theory and low and behold…they were right! Charging me more for my fuel…Bast**ds! Now I can’t belive I never actually checked this before!
As you can see, 1 Litre should cost 123.9 pence, when I put exactly 1 Litre in it came to 125pence!”
(Attila ッ Boros, unedited, via Facebook)
So, is this for real. And if it is why would the company advertise the “scam” right there on the pump for everyone to see?!? Read the rest of this entry »
