Installing Google TensorFlow Neural Network Software for CPU and GPU on Ubuntu 16.04 by https://is.gd/KfiGpp

TensorFlow is an open source software for performing machine learning tasks. Google, its creator wanted to expose a powerful tool to help developers explore and build machine learning based applications and so they released this as an open source project. TensorFlow is an extremely powerful tool specializing in a type of neural network called the deep neural network.

Synkron: a flexible & powerful way to synchronize your files or folders on Linux – An “encrypted” example for security and privacy reasons

Sometimes it is really easy, other times you waste your time. A good synchronization between files or folders is something you need everyday but it could become a nightmare if you miss something.

In my specific case I need to automate a synchronization between a folder (F1) where I usually save my office files (Documents) with a second folder contained, for security reasons, in an encrypted volume/partition (F2). This last folder (F2) automatically synchronize its content with a third folder (F3), located in the same encrypted volume/partition, that is the client folder of a remote storage hosting (F4).

This also means that when I am out of the office and I add a file in the online storage host (F4) the document is automatically copied to the client folder of the remote storage hosting and to the folder located in an encrypted volume/partition (F2 and F3).

Moreover, I need to erase the Documents folder F1 as soon as it is synchronized with its mirror F2 in the encrypted volume.

The described scenario is common in the everyday working life and it is conceptually not hard to solve… in theory… When I tried to set up the above described operations using grsync on Fedora and Ubuntu I had big problems to obtain an acceptable result.

Many times the synchronization was unidirectional and I was not able to run it properly just using grsync still I found one right solution with Synkron. Synkron  is a multi platform software (Linux, OSX, Windows and portable) written in C++ that is really flexible for all multitasking synchronization needs.

First of all, Synkron is multi-tab and this is a winning features because it let you to “slice” any problem (synchronization matter) into simple, easy to solve, tasks.

In my example I determined the two Folders I wanted to sync – F1 & F2) and  decided thath both folders had to be considered as Master by the software.

Then I used the Advanced Menu and I chose to “Move contents to Folder 2, leaving folder 1 empty” and to “Store database in a text file” for my convenience (F1 to F2 deleting F1 contents after synchronization).

At this point, I opened a second synchronization tab where I selected two folders (F2 to F3 sync) and I also asked Synkron to “Synchronize hidden files and folders” and to “Detect collisions”.

At this point I had obtained an acceptable solution to my initial task, simply dividing my problem into two separate operations.

Moreover, I’ld like to focus your attention on the fact that Synkron has a specific feature for multi-synchronizing three or more folders at the same tome. The tuning of this particular feature is really intuitive and you can also selected many of the different advanced options we described here above.

If you have complex synchronization needs and you have many tabs configured you can always choose what tabs you want to activate or deactivate using the “Sync folders” option you find in the upper part of each tabs. Another option for this specific issue is represented by the SyncView visualization that let ypu to have a quick general glimpse about the state of all the sync and multisync tabs.

Synkron has simply fantastic scheduling options that are able to solve any need you may have.

Furthermore you can decide to automatically synchronize your folder as soon as you launch Synkron.

You can also decide to automatically run Synkron at the startup but, in this case, you need to manually configure your Startup Menu.

As extra features you can always decide to create Blacklists that will exclude specific files, folders or extensions from the synchronization.

In addition you can define Filters by extensions to better refine your synchronization.

Last but not least, when you run Synkron you obtain a detailed report in real-time where you can check the state of operations by colors.

Pandora for “dummies”…. when you are outside the USA… – Firefox, Chrome and Opera add-on –

The last time I wrote a post about connecting to Pandora  when you are outside the USA was just (sic) three years ago. Meanwhile a lot of things changed and Anonymox, the Firefox add-on and proxy service I suggested in 2012, it is not free now.

It happens but when my nephew asked me something similar and really intuitive to connect to Pandora I was in trouble… more in trouble than I could imagine…. In fact when I started to search something alternative, I found a lot of very good proxy add-ons for Firefox. It was a pleasure to discover some of them because they are technically well done and offer a lot of flexible features for privacy purpose. But this is not the topic of my post… for today.

After many unlucky trials, where I tested different add-ons that were not able to guarantee a minimal rate of usable connection,  I found ProxMate .

ProxMate is an open-source, SSL proxy manager for real dummies. As Firefox add-on you can install it on your browser in just few clicks and then you practically don’t need to configure anything. The only requested thing after installation is to decide the websites and services you want to connect through ProxMate. The internet connection has a good speed rate and the music flows as silk through your Pandora account.

You can install ProxMate searching it through the add-on panel you find in Firefox or you can decide to directly open the link from the  ProxMate website. After the installation ( no restart required) you have to find the “shark fin” icon into your Firefox bar. If you don’t find it immediately, you have to manage your icons and manually personalize the bar.

Then, click on ProxMate “my button” icon and select: “Install New Packages”. You are redirect to the ProxMate website where you can select Pandora or others interesting websites (e.g. Netflix, iHeart Radio, etc..) with specific IP restriction policies. 

Now, you select your desired website/service and follow the instructions (click selection) that will appear on the screen to complete the installation.

Last but not least, don’t forget to click again on the ProxMate icon and enable the proxy service.

As usual, I recommend to NOT forget to disable  ProxMate (as every other proxy server) when you don’t need to use it.

Oops, I forgot to say that ProxMate is free of charge……. Enjoy it!!

Blogilo: the Linux blog client to create new posts on your local computer

Yes, I know! Talking about Blogilo is not an hot news but the “recent” version 1.1 (according to the Help Menu in Blogilo software) has added some new features and something has changed. Some years ago, when I tested Blogilo, I thought that this software was a good “concept” but it lacked of too many features as compared with e.g. online WordPress.com platform. With version 1.1 these lacks have been reduced and now Blogilo becomes interesting if you are looking for a software that could be used daily for offline posting.
Blogilo now has less bugs than in the past and it is possible to write posts with just few seldom crashes. The user interface is intuitive and after the installation you spend just few minutes for adding and setting your blog. The positive thing is that Blogilo works with all the main blog platforms and it could be considered as one of the most complete blog client for Linux.
The matter is that blog platforms evolve quickly and Blogilo, as all its competitors, seems to be slower than many of them. In fact, it could happen that some up-to-date features are immediately not supported and you have to manually modify your post and adding them directly through the host website (e.g. WordPress). 
One of the most annoying problems I continue to have with Blogilo is about wrapping text around the image/picture I am used to put at the beginning of every post I write. It is a simple matter to solve but at every post I have to manually change the html code. 
As for my experience you have two different ways to solve this isssue.
The first is to edit the image/picture after you inserted it into the post and add the value “allign” selecting the right options in the Advanced Menu (why the Advanced Menu is not available when you insert a new image/picture?).
The second (faster) is to go to the Html Editor tag into Blogilo and add this code at the end of the image <img> tag:
align="left"
For example writing this post I added:
<img src="http://i119.photobucket.com/albums/o158/galigio/blogilo_logo_zps3pmqrnq1.png" align="left" width="160" height="105">
Simple to solve but really annoying when you have so little time to dedicate to your blog….
To sum up it is possible to affirm that Blogilo really contains all the features to write a blog but if you need something more professional you have to spend some hours, after the installation, to learn how to find the right solutions for your specific needs.

How to obtain a free digital signing service for your personal documents

Sooner or later you need to digitally sign a document. If you have never done it before it’s only a matter of time, you will need a digital signing service sooner than you can imagine. The problem is represented to be ready without being obliged to spend money for it.

You will find different offers online and many trusty companies will try to convince you that their offer its the best but many of them limit your possibility to freely sign documents when you really need.

During my tests I tried a bunch of them and, for my experience, just few worth any attention.

In particular I was positively impressed by hellosign and Adobe Echo Sign. They are both interesting but hellosign offers something more. I mean you have not to spend a cent for both but Abobe limits the number of documents you can free sign to just 5 documents each month. If you are not used to digitally sign your docs this limitation doesn’t represent a problem but, trust me, when you will begin you soon need more than 5 free signatures a month.

HelloSign also allows you to upload an image file with your handwritten (and, of course, scanned) signature or create a new one choosing between some different fonts. You have no limits for signing documents but you can send only three signature requests a month (enough for my present necessities). Moreover, you can browse into the hellosign Documents folder and find all the  documents you have signed before.

On the other hand, Adobe Echo Sign request more personal information when you sign-up for the service and, as we already underlined, it limits your experience to just 5 activities a month.

Try them and let us know if you have already found a better, free, online service to digitally sign your documents. Good luck!  AddThis
