Is this normal? Background Play Store data consumption has eaten more than 13% of my data plan :-(

Photos (Android app) question

I'm experiencing the following:

- I shoot some photos on my smartphone
- When WiFi is available, photos are uploaded to the cloud. If I use the Photos webapp, I can see them there
- On my smartphone, I use the app (Device Folders) to delete the local copies of photos
- On my smartphone, I use Gallery to verify that photos are really gone
- Some time later (maybe one night?) photos reappear on the smartphone as local copies, as if they had been downloaded from the cloud. And I can also see them in Gallery
- Deleting photos using Gallery seems to really nuke them from the smartphone.

I have just tried the alternative, ie using the Photos app (Device Folders) to delete them for the second time, but it's too soon to see if that's working. One things I've noticed is that after the second delete, the Assistant is now telling me that 10 photos (those which I have deleted) are waiting to be uploaded :-(

So, my question is: is it normal that after deleting photos from Device Folders they reappear after a while? what's the rationale behind that?

While searching to solve a problem at work, I have discovered a new way to make presentations, www.prezi.com. It's extremely nice, as it blows completely away the traditional idea of slide and transitions and replaces them with high impact animations and a "voyage" through the whole conceptual schema/structure which is at the base of your presentation (loosely similar to a mind-map)

Great!

It's not easy to describe how Prezi rethinks the idea of presentation, so: ignore the subject as it will probably won't interest you, but have a look at the presentation below, it's really worth to know about this tool.

Help Needed: Exchange 2010 Backup problem

I'm starting to bang my head on the wall on this... :-/

I have an Exchange 2010 running on a 2008R2 virtual server. Two months ago we started switching from Blackberries to Android (Samsung S5 mini). Each smartphone is configured with an Exchange account, and work properly in daily use, but at system level I can observe that:

- transaction logs have increased to almost tenfold size
- backup times have gone from about 3 hours to almost 9
- database growth is normal, and not even comparable to daily trasaction logs' size

Using ExMon and MS's IS log analyzer I couldn't find any particular culprit mailbox (with stuck messages, corrupted events, and similar problems), but I see a LOT of ActiveSync activity coming from all the Android clients.

My current hypothesis is that ActiveSync is using a lot of Ping, Sync and FolderSync commands, which dirty the database pages, although they don't cause an increase of their size. This would explain why backup now takes ages: because it has to rewrite a lot of pages, whereas before Android it would skip most of the writes since a lot of blocks would be identical to the previous backup.

But this is just an  hypothesis, since we are in black magic area here, and I cannot find anything to confirm my ideas. 

I know that in the past iDevices could bring an Exchange server to a crawl, but that has long been fixed, and TBH the few iDevices which are connected through ActiveSync are using far less resources than the average Samsung.

There are also some non S5 mini Android devices attached via Active Sync, and they generate a similar activity.

The two mail databases sum up to almost 400GB, of which about 80GB are free. I will try to move all mailboxes to new databases, in order to recompact them without turning off the server, but my feeling is that there is something wrong which will only be alleviated by a DB size reduction.

If you can point me to some article which can throw light on this problem, you'll save a wall from being smashed by my head :-)

Thanks!

Thanks +Maurizio Bertaboni but my problem is with Android terminals, rather than iOS. iOS devices are performing very well when compared with Android, with a below average number of Pings, Syncs and FolderSyncs and no signs of generating excessive transaction logs.

My problem is indeed with the growth of transaction logs, not IIS logs. IIS logs have grown from 10MB to 60MB/day since we introduced Android, but considering that we have tens of devices in use I think it's a reasonable growth.

But what is creating a lot of problems is the growth of transaction logs and the (I suppose) related slowness of backups. Last night it took 10 hours to backup what took 3 hours two months agos :-(

I've had very little time to stay on the problem today, I'll return to it tomorrow, and update this post if I can discover something useful. Hopefully...

Thanks again!

Oldie but goldie, this app does its metering nicely and precisely, and from today the real time traffic info feature is ad free, and can help in tracking down bandwitdh hungry apps.

A must have in Android's toolbox!

Neither GDrive nor OneDrive support authenticated proxies, only unauthenticated ones...

What's the rationale behind such a choice? How is an enterprise user supposed to use such products on his/her PC? At enterprise level, content filtering and proxies are standards, how can Google and MS ignore that most proxies are authenticating?

BTW: For those wanting to go the unauthenticated way with GDrive, here is the official list of URLs to unlock: https://support.google.com/docs/answer/2589954?hl=en

Gone Down to the River to Play #TwoDots playtwo.do/ts

A bit harder than the previous ones, but relaxing and enjoyable nonetheless. And Two Dots still my solitaire of choice, of course!

Just a quick reminder, this is going to expire tomorrow, and you could lose 2 or 3 bucks by not exchanging it :-)

Dear Google Photos, I hate you.

I guess you have decided to reindex my photos, and now they're lost. Not only they are not shown in the main Photos page, I cannot even retrieve them using a query, as was possible during the first days since launch.

I can see some more photos if I access you via Google Drive, but still I have no way to find a lot of images I know are there, but in an unreachable limbo.

Maybe some people like this "smart" management, but is it too much to ask for a full, complete, and totally dumb view of all my photos?

Thanks

The problem is with the photos themselves. Sometimes they lack the metadata to correctly work out the date they were taken. I found that it depended on which camera I used to take them with.
