Firefox 54: more multi-process content processes by https://is.gd/7xLhyI

firefox-multiple-content-processes

Mozilla plans to increase the number of content processes of Firefox’s multi-process architecture to four (from one) with the release of Firefox 54.

Some Firefox installations are still not eligible for Firefox’s multi-process architecture. This includes systems with accessibility tools or settings enabled. Multiple processes won’t be enabled for users with extensions either, regardless of whether those are legacy add-ons, or WebExtensions.

Mozilla ran its memory test again to determine the right number of content processes. An increase in the number of content processes for the browser always goes along with an increase in memory usage.

After microcontrollers and embedded programming for, ermm, the sake of programming, the next hot thing is: AI at DIY level.

With AIY Projects, Google claims, Makers can use artificial intelligence to make human-to-machine interaction more like human-to-human interactions. They promise to release a series of reference kits, starting with voice recognition.

TrueCrypt – Try it again! Waiting for CipherShed…

truecryptlogo_256TrueCrypt is safer than we thought! A specific audit tested TrueCrypt 7.1 unmantained through a complex verification process and the results are surprising.

First of all we have to consider that TrueCrypt is not mantained since 2014 and that its “natural” fork, VeraCrypt, is directly developed by Microsoft. For this simply reason many former TrueCrypt users prefer not to use VeraCrypt.

Secondly, the bugs revealed by the testers in TrueCrypt are less worrying than that discovered using its competitors solutions.

For this reason I decide to install TrueCrypt (that I use previously it was unmantained) on my Fedora 22 laptop.

To begin, I searched for a good repository and, at the end, I opted for that mantained by GRC. So I downloaded the TrueCrypt 7.1 archive from GRC that is still storing all the others TrueCrypt versions.

I decided to use the 7.1 version because it has more features than the last 7.2 version (the last known release of TrueCrypt). In any case I am monitoring the Swiss website and I wish that the CypherShed project will be completely developed soon.

After I extracted the file and moved it to a specific folder.

Last but not least I opened Terminal and typed:

sudo ./truecrypt-7.1a-setup-x64

and the software was correctly installed into my Fedora 22 OS.

After some tests I can adfirm that TrueCrypt is still a good security solution not only for the above mentioned audit but also because it is really stable, flexible, full of useful features and simple to use.

To sum up: Try it… again!

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.
