Dropbox arghhhhh you goofed.

Like many others I have become dependent on Dropbox to share files between the various internet connected devices in my life. A recent update to the mobile version of Dropbox for Android made an such an enormous boo boo that I am surprised that there has been no outcry about it.

To understand the gaff you must understand how Dropbox works on mobile devices. On a normal computer Dropbox keeps a full copy of every file in your Dropbox folder and constantly keeps these files updated via the internet. This approach would be far too expensive in memory and data allowance for a phone so the mobile version of dropbox does not keep a local copy of every file but instead only downloads files to a cache directory as you need them. Once you accept that you have to manually upload and download the system is a reasonable compromise and programs can still work on the copy of the file stored on the cache directory.

So far so good but a recent update to Dropbox made several changes. First they moved the location of the cache from /mnt/sdcard/dropbox to /mnt/android/data/ This change is more of a nuisance than a serious problem because it breaks any links in programmes that used files stored in the cache directory.

The real gaff however was that the update deleted the original cache folder and everything in it. Deleting user data files is always a no no. I was unfortunate enough to be in an area without internet when I realised what had happened and I was rightly annoyed to discover that my offline versions of several key data files had ben deleted. Others may have lost recently changed data files that had not yet been synchronised to the internet.

Terrible move Dropbox. Never delete a user's own data files without warning.

My First Gaming Mouse: Logitech G300

I bought a gaming mouse yesterday a Logitech G300, here my initial thoughts. What is a gaming mouse?  There are a wide variety of devices available classified as gaming mice but a few features  seem common: 1. Wired rather than wireless: Although some high end models are wireless wired connections are just better and faster than wireless so most gaming mice stick with wired. As a bonus wired mice don't need batteries so the mouse is lighter.  2. High response rate: 1 to 2ms response rate so the mouse immediately responds to input.  2. High DPI. Gaming mice invariable boast high DPI numbers from 2,000 DPI upwards. This makes the device very responsive to the smallest movements.   3. Adjustable DPI . High DPI improves responsiveness but reduces precision so gaming mice generally allow you to adjust the DPI down for precise work such as pulling off headshots in sniper mode. Generally the mouse allows dpi to be changed on the fly by pressing a button.  4. Extr

Android Tip 3: Sharing a Folder between multiple users of an Android device

Android has allowed multiple user logins for quite a while now. This is can be very useful for tablets which are shared by family members. Normally Android erects strict Chinese walls between users preventing them from using each others apps and viewing each others files. This is a useful security feature and ensures your kids don't mess up your work spreadsheets when screwing around on the tablet and should also prevent them from buying €1,000 worth of Clash of Candy coins on your account. Sometimes however you really do want to share stuff with other users and this can prove surprisingly difficult. For example on a recent holiday I realised that I wanted to share a folder full of travel documents with my wife. Here are some ways to achieve this. 1. If you have guaranteed internet access  then you can create a shared folder on either Dropbox or Google drive. Either of these has the great advantage of being able to access the files on any device and the great disadvantage of bein

Portal 2 two screen coop on one PC.

I mentioned before that I intended to try Portal 2 in "unofficial split screen co-op mode. Well split screen on a small computer monitor is a recipe for a headache especially when the game defies gravity as much as portal. However a minor bit of extra fiddling allowed us to drive two seperate screens from one PC. The Steam forums describes a complicated method of doing this that I couldn't get working so this simpler method which worked for me might be of use to someone. 1. First I followed the instructions in this post to get split screen multi-player working: A minor issue not mentioned is that you need to enable the console from the keyboard/mouse options menu I am using keyboard and one wired Xbox360 controller as suggested. Getting the controller to switch to channel 2 was tricky at first but as Chameleon8 mentions plugging it out and in again during loading works. The trick for me was to do the plug / p
