Stuff that occurs to me

All of my 'how to' posts are tagged here. The most popular posts are about blocking and private accounts on Twitter, also the science communication jobs list. None of the science or medical information I might post to this blog should be taken as medical advice (I'm not medically trained).

Think of this blog as a sort of nursery for my half-baked ideas hence 'stuff that occurs to me'.

How to read PDFs, and other docs, offline on an iPhone using Dropbox

Shortened link for this post is http://is.gd/hlKJC

Note - there are other ways to do this, I just happen to have used this one to save files to my iPhone. 


I was inspired to dig out the draft text of this post after reading a Facebook status update from my friend David Bradley aka @sciencebase recommending the service. As far as I'm aware Dropbox works perfectly on an iPad although I don't have one of those so can't confirm.
 

General guide to using Dropbox While I can't pretend to understand the minutiae of cloud computing Dropbox is an example of this sort of thing. With a free account (which gives you 2GB of storage space) you can access your files via the internet from any networked computer. But, and this is important, your files are also stored as a local copy on your own machine - you just need an internet connection to synchronise them with the online version.

On downloading the Dropbox software (I don't think it's very big) it will create for you a Dropbox folder within your own file architecture (you can choose where it goes) and you can start putting files in there. I have Dropbox downloaded onto my home and work computer and the files that I tweak on those computers appear, miraculously ready-tweaked, when I get into work and vice versa. If your internet connection isn't working and you make changes to a file it will remain on the computer on which you edited it, but it will be unsyncrhonised with your other Dropbox.

You can tell the health status of each file and folder as there's a little green tick next to any file / folder which is up to date and syncrhonised, there's a rotating blue icon to indicate one that's being updated and when you open a file to work on it will have a red cross next to it (you need to save and close for it to update). So if you want to try this go to http://www.dropbox.com/ (they have a video there you can watch to tell you more about the service), create an account and sign up.

And now a word from our sponsors :)

Anyone can sign up for free 2GB but if you know someone who already has an account ask them for their 'referrer link' which can net you an extra 250mb - @sciencebase's referrer link is https://www.dropbox.com/referrals/NTgzNTg5MDk (Disclaimer: he isn't actually sponsoring me, I just like that phrase - my referrer link's at the end of the blog I'm just giving him top billing as he inspired me to update my post).

'MakeUseOf' have written a free guide but I confess I've not actually looked at it as I'm very familiar with Dropbox, but here it is http://sciencebase.tradepub.com/free/w_make17/prgm.cgi
Edit: Originally I mistakenly said that David had written this but he let me know that it was another company so have edited the above sentence.

You'll need an email address and a (self-created) password to log in - once you've installed the software you won't need to log in to use your files on your computer(s), only if you want to use the web interface. The web version is good - you can upload and delete files (but to edit them you'd have to download, delete and re-add so better to use your Dropbox folder for that).

A very easy way to sign up, if you don't want to start from scratch, is to ask one of your friends to send you an invite to share a folder with them - this will lead you through the process quite nicely.

Dropbox on the iPhone
The iPhone Dropbox app is free from the appstore so all you need to do is download it and log in. Your files will then synchronise and you can read them online. It can open most things - I think it used to struggle with .rtf but that may have been fixed now. Most of mine are .txt, .doc, .ppt and it handles them fine. I can't remember if it cares whether it's .doc or .docx so you might want to double check.

For me, the big bonus is that you can open any file while connected to the internet and favourite it (using the star icon at the bottom of the iPhone screen). This means that if you need to access it in a low signal area you'll be able to. In the settings section (available from the app's start screen) you can set the size of your local storage (mine's 200MB but you can go up to 1GB). If you download the free PlainText app you can sync it (the default is a single PlainText folder but you can tweak it to sync with all your folders) and you can create new .txt documents on your iPhone - ie you can type something on your iPhone and then pick it up at your desk or at home. Nifty.

EDIT: I read a comment on one of Ben Goldacre's (secondary) blog posts which highlighted that this also works for .mp3 files etc. etc. Of course it does, why didn't I think of that??!!

What happens when you exceed your storage space?
I once did this - don't forget that if you share Dropbox folders with other people then all of the contents you share adds towards your 2GB limit and it soon adds up. No files were deleted but I couldn't save any edits or add new files until I moved or deleted some older files. My only annoyance with Dropbox is that it didn't tell me there was a problem until I was at 2.5GB and had it mentioned it sooner I'd have pruned some files with less stress. But all was fine, but it's not a bad idea to check periodically what percentage of your allowance you're using.

Be aware though, that if you delete a file on your computer it isn't permanently deleted - this is often a good thing if you delete in error as you can undo this. As far as I can tell, 'deleted' files may actually contribute to your storage space - you can log in to your web account and choose the option to show deleted files, you'll see them in grey. You're then given the option to delete these permanently. Deleting files is a two-step process which, in the long run, I think is no bad thing - but useful to be aware of in case your storage starts to rack up.

I've been using Dropbox since January 2010 and am very pleased with it - I am not affiliated with them or anything dodgy like that :) ...and my referral link is https://www.dropbox.com/referrals/NTQwMDAxMDQ5

Comment policy: I enthusiastically welcome corrections and I entertain polite disagreement ;) Because of the nature of this blog it attracts a LOT - 5 a day at the moment - of spam comments (I write about spam practices,misleading marketing and unevidenced quackery) and so I'm more likely to post a pasted version of your comment, removing any hyperlinks.

Comments written in ALL CAPS LOCK will be deleted and I won't publish any pro-homeopathy comments, that ship has sailed I'm afraid (it's nonsense).
