Dropbox Uploads (Needlessly?) Consume Available Space On Phones

I notice that the Android Dropbox app, when uploading a file to the Dropbox server, first copies the source file to a cached file in a hidden folder on your phone’s system storage. Then it uploads the cached file to the Dropbox server.

Why? I don’t know for certain. Maybe the app developers wanted to ensure that the source file isn’t altered or deleted during the upload process. First caching the file is a conservative tactic. 

So what?

The cached file consumes precious system storage space on your phone. On my phone with 8 GB system storage, this is significant.

Regain lost storage space

To regain that space, delete the Dropbox cache. You can do this from within either the Dropbox app or Android’s settings (Applications, Application Manager, scroll down to Dropbox and press the Clear Cache button).

Dropbox explains that Dropbox’s cache folder is hidden.

It would be nice if the Android Dropbox app allowed the user to choose whether the Dropbox app first cached the file before uploading it. Oh well, no app is perfect.


Speed Up Twitter On Android 

I’ve been using Twitter on my Android phone and noticed that over a period of days or weeks it slows to a crawl. A simple way to kick Twitter back into high gear is to exit Twitter and just delete all of its data, and then restart Twitter.

On my Android 5 phone, I go to Settings, Applications, Application Manager, and scroll down to Twitter, then press the Clear Data button. You’ll be asked to confirm. Click CLEAR – you do wish to clear all data.

Exit Settings and Restart Twitter. It should find your profile(s) and download your tweets. Now it should be faster.

Try this at your own risk. It works for me, but your mileage may vary.

Piscine DELIGNY, Paris

When I travel, I like to find local swimming facilities. The oddest — and most charming — pool was Piscine DELIGNY, a floating barge that contained a swimming pool(!), on the River Seine in Paris.

I’d guess that the pool was about 25 meters long by 15 meters wide. It was surrounded by two decks of private changing rooms. This superstructure hid the pool from the outside world and gave the pool and surrounding pool deck a cozy private atmosphere.

There was even a unique “ski nautique” concession: a speedy winch powered by a powerful electric motor would quickly pull a skier from one end of the pool to the other! It’s the oddest skiing contraption I’ve seen anywhere. The ski ride was fast but brief.

In the mid 1970s, while in Paris for a few days, I first found this unique pool. France — even rural France — has some great swimming venues, but this was unique.

Video from 1973

From Vogue:

This is the deck in La Piscine Deligny, Paris, 1975, perhaps the most glamorous public pool in history. It contained wood from a boat that transported the body of Napoleon Bonaparte. It was frequented, over the course of its 200-year life, by kings, by Grace Kelly, Audrey Hepburn, Errol Flynn. “Do you remember that day?” I ask sort of naively. Looking at Schlesinger’s photos, you tend to imagine a story lurking below the surface of each image. “Every day was like that,” he says, laughing. But of course.

Alas, nearly 20 years later, La Piscine mysteriously sank to the bottom of the Seine, never to be heard from again, so Schlesinger’s shot of its loungers, like all of the pictures in A Photographic Memory, offers a blissfully carefree record of a lost bohemia.


Deligny pool, or bath Deligny, a floating pool was open air on the Seine, moored on the left bank (Quai Anatole France, in the 7th arrondissement of Paris) since 1796. She included a restaurant and private dining rooms.

The BRANDT brothers (Edgar and Jules), among other famous swimmers, swam here beginning in 1898.

Deligny the pool was the place of the swimming events of the 1900 Olympics.

It was a popular place where you had to be seen.
