Over the past four days I have been in Edinburgh and then in London, which is why I have not been able to post anything. Stay tuned – I am back to Toronto tomorrow. Incidentally, I can’t say that I am impressed with the hotel internet. When it comes to uploading fairly large graphics I like to use on my blog, things often fall apart. Somehow this have been particularly problematic on this trip (there are other reasons too…). This reminds me: those of you who regularly submit papers to scientific journals and have to wait for several days to hear a response – try to see if you tend to upload ridiculously large SI files. If you are a journal editor, you know that it is a nightmare to download some of the NMR graphics people put together these days. My advice: use low resolution graphics. I am definitely on the receiving end of this in my capacity as one of the Associate Editors for Organic and Biomolecular Chemistry. I can’t deal with large SI files while travelling and staying in hotels with slow internet. This, of course, creates needless delays for the authors. The best way to go is to export your giant .pdf file into a .jpg and then convert it back into a .pdf. This seemingly senseless process will give you a much smaller .pdf file. I learned this from Adam, one of my graduate students.
