Observation:
AdBlock is a thing. A lot of people shield themselves from ads using it. Some adblocking software also blocks tracking pings (e.g. Google Analytics and Gemius). Today I've noticed, that Gemius changed a method of tracking page views, they've introduced a redirection:
1. first party redirects to Gemius with a back-url set as GET parameter
2. gemius saves a visit and redirects to back-url

It's interesting, I've never seen such behaviour before on a trusted websites. I guess it's a time for even more sophisticated privacy-aware browsers/plugins.

I will check next time I encounter it. But they can pass any data they want including first-party cookie or id.

Google Drive Bug:

1. Create a directory.
2. Upload some files.
3. Rename files so they look nice (date_string_part.mp3)
4. Share directory with people having link.
5. Click on link to check if it works.
6. Try to open a file.
7. The warning says the file is too big to be scanned. It shows the name from before the change. It may scare people.
8. When clicked "download", the prompt file name is the new file name (as expected).

The lack of control

Did you ever used this awesome app through webpage and wanted to save results? It allowed you to choose between Dropbox, Google Drive etc. Cool. No, no, wait, not cool. Most apps want the access to the full content of your cloud drive. I'm sure that at least Dropbox supports a directory permissions. But you know what? It doesn't allow a user to restrict app to a directory. It's totally up to the app. But devs of these apps either don't care, don't see a value in it or purely see a value in accessing all your ifles. So for a user it's all or nothing. A bit like Android up to date (new version is going to have some more extensive permission policy).

The lack of control makes most my cloud storages useless except backing up some files. In offline world I can always unplug harddrive...

Adding a user flow to Android sometimes sucks :
1. Add new account to Android
2. Google asks to give phone number to verify
3. one cannot change view to check sms because account adding app blocks it

And yes, I know there's a bug on this problem, I've filled it myself ;-)

I've read "ImageNet Classification with Deep Convolutional Neural Networks" by +Alex Krizhevsky  Sutskever, Hinton: http://www.cs.toronto.edu/~fritz/absps/imagenet.pdf.

In section 4.1 they write about doing PCA on a RGB pixels. I'm trying to reproduce it by:
1. compute covariance matrix (for a test i use: numpy.cov)
2. compute eigenvalue/eigenvectors (numpy.linalg.eig)
3. draw random vector a (3 elements)
4. compute a quantity to be add to an image rgb values

The computed values are big for red component of pixel (mostly >150 from range 0-255). I'm wondering if they've seen the same. The resulted images looks somewhat weird.

Also, did they apply it only to train set? (i understood that yes)

I used the PCA approach but I had a very different dataset and actually found a simple random noise vector worked just as well for me

Google Maps user story 1
I click on a "show on map" button on Facebook event. It opens a Google Maps with a route from my location to a given destination. Cool. Now, I want to mark a place by a star, but no matter how I click on map, it's not possible :-(

Google Maps user story 2
Shows my location marked by a dot, I type a name of the street and building number. All the suggestions shown are in different cities, so I have to put the city name explicitly, despite being around 500 meters from the destination. It's very frustrating 'feature'.

I've decided to beta test Android M. It's super awesome. The privacy is much better, it starts to exist, more:

http://www.androidcentral.com/using-app-permissions-android-m

tl;dr; one can restrict access the apps have to smses, contacts and others private stuff which were touched by a lot unrelated apps for unknown purposes ;-)

Android warns that apps were written with old Android in mind, but I've not encountered any issues so far. (I mostly declined access to my data for things that should not access it anyway, now I can install Fb messanger and What'sUp ;-) )
Google is finally giving users more granular control over permissions in Android M, but it's probably going to be a rocky start. We've long pondered what it might look like if Google decided to implement something that gave users more control over what individual apps are allowed to access on our devices, and at I/O this year it all became clear. Android M is going to allow users...

I'm working on a problem which at first sight is similar to classification. The classes are discrete numbers 0-5. The first thought was to use a cross-entropy cost function, but this strips the network from a knowledge that the output classes are related, it's a scale of intensity of a phenomenon on a picture and because of this, the error between 0 and 3 should be bigger than error between 0 and 2.

I thought about: adding one linear layer summing an output from previous layer having 5 binary neurons and using mean square error.

I'm looking for similar problems, papers, tutorials, cost functions. Any suggestions?

+Paweł S Yes, the last layer in such model would be linear.

Some people probably have this problem:
 - have Chrome with 20+ open tabs,
 - PC restart / crash, Chrome is killed unexpectedly
 - PC and Chrome restarted
 - Chrome asks, whether to reopen old tabs, say yes
 - all Google owned websites freeze, gmail/G+ work until Hangouts loads and then die
 - only pkill chrome solves an issue, just closing/opening doesn't work

Edit:
I've worked around the problem by installing an extension "Session Buddy" and never clicking "restore" in Chrome:
