An appeal from Arup:

Over the last few years, I’ve been working on this website, and have produced a lot of useful content, small and large project guide, some open-source works. I have made most of it available on my site, all under appropriate Open Source License.
Working on these requires much time, skill and a lots of patience. I try to answer to queries put as comments in the website at my earliest.
I’ve hesitated to put up a donation option previously, but now it may be the right time. The maintenance costs for running this website and all of my developments are really crossing my financial situation. I have no job and am a student.
Any size donation would be appreciated, and you’ll receive a personal thank you email for your donation.
All donations are voluntary/optional, so if you choose not to make a donation, you can still use all the information available just as before. But please make a donation, if you can afford it.
There are two types of PayPal donations accepted.

Monthly recurring donation,

 


Subscription options



 

and one time donation.
