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.

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.

Online Speech to Text Recognition

radio64It’s fast, it’s immediate and it lets you to write an email or a text in a while, anywhere you are. When you use a mobile, you need to find the right app. For my experience the universal app for this doesn’t exist. It depends on the model of the mobile in general and in particular on the type of the installed microphone. This means you need to test different apps to fins a suitable solution for your specific needs. But usually it doesn’t keep much time.

When you are at home or for more complex works that need to be directly edited on a PC, you usually cannot use any Android app and so you need a similar tool. This is my case.

If you google it, you will find different solutions. Some of them are desktop software that can be installed and settled up in a reasonable time (usually few hours). These software are really accurate and have many tools that allow you to develop complex texts typing just few keys to refine some inaccuracies. The “problem” is represented by their cost that, for some products, is high (… certainly, we are talking about few bucks…). 

Instead, a good solution could be the online -speech to text- tools offered by different websites. They are usually free but you need to be obviously connected to the web if you want to use them. 

Furthermore the text results generated by these on line tools are connected with the particular model of microphone you installed into your PC. Also in this situation you can find enthusiastic reviews for an on line tool that is completely ineffective for you. And as for Android apps you need to spend some hours to discover what is the best online tool for your needs. Last but not least to use them you need to authorized Flash (sic! yes the nosey Flash…) for managing your audio hardware.

In my experience, after some tests, the best sites offering  -speech to text- tools are four:

  • Speechlogger that is really simple to use and the most versatile as for exporting the “written” text but it works just on the Chrome Browser (version 25 or later) and this is a big limitation when you are fond of Firefox:
  • TalkTyper that is also complete and it is supported by different browser (Firefox included);
  • Dictation that is very minimalist as web graphics but it really does what it promises in every browser…;
  • SpeechPad that  is very complete but it requires a free registration to use the -speech to text- feature. There are two big features offered by this website. The first is about that it has a good grade of recognition for speeches in Russian. The second feature is represented by the possibility of using an audio file or an url redirecting to audio files and/or video (but only for YouTube or HTML5audio/video).

Some of the above described websites have a large selection of different languages you can be interested to use. Others have a narrow choice of languages but for the accuracy of the -speech to text- work, could really be what you are looking for.

So, to conclude, if you need a -speech to text- online tool, you have just to invest some hours to find the right website for your needs. When you will start to use these kind of online tools you save a lot of time that before you spent for typing.

A small collection of Firefox add-ons you can install to improve (a little bit) your privacy – Part 3

In the past two years the EFF – Electronic Frontier Foundation –  has released a couple of add-ons specifically created to improve your privacy when you are on Internet. Just for a quick information, EFF is a no-profit organization specialized in, but not only, the defense of  privacy and free expression in the contemporary “world of emerging technologies”.

The first interesting EFF add-on is HTTPS Everywhere  that forces websites to provide https webpages also when you (better: your browser) asked for a “common” HTTP connection to their servers. This happens automatically and you don’t usually notice any delay in your navigation speed. HTTPS Everywhere is a precious add-on because it improves the number of “secured” connections when you are on Internet and decreases the risks of information leaking during Internet navigation. Moreover, this add-on is available not only for Firefox but also for Chrome and Opera and, at the moment, could be considered as the most versatile and -simple to use- tool you have to increase the use of HTTPS navigation. HTTPS Everywhere could not be considered as a bullet-proof privacy guarantee but it really does what he promises. Last but not least, it seems that if you adhere to their anonymous data collection about usage, you can really help them to discover false HTTPS certification disseminated through the web and contribute to a safer Internet.

If you want a little bit of security and think that every website should allow to connect through HTTPS, you should try HTTP Nowhere  that blocks all the unencrypted web communications. As for what we described for Flash add-ons (Flash Control and Flash Block) the level of security depends on your choice. HTTP Nowhere is a more “radical” choice but, i any case, it can be widely configured to your needs. For example it allows you to create a whitelist of HTTP websites that will be never blocked. Moreover HTTP Nowhere can be configured to visit .onion websites through TOR.

In  any case don’t forget that HTTPS connections are only relatively more secure than HTTP ones. As someone commented, HTTPS effective privacy depends on Certificate Authorities reliability and seriousness and, in some cases, HTTPS could be easily eluded. 

The other EFF add-on I’d like to focus your attention is the Privacy Badger . This add-on has the same goals of the most famous Ad Block or Disconnect but it works in a different way. In fact its work is not based of previously compiled list the needs to be updated frequently but on an heuristic examination of trackers behaviour. It could be considered “democratic” because it doesn’t automatically ban trackers at all but analyzes if they are looking for your web habits or they are “just” recording your passage in a specific website. In this last case the Privacy Badger will observe their behaviour during your next navigation and, if they persist to track you, it will label them with different colours (green to yellow to red) blocking them when they become too intrusive for your privacy. The PRO is that also a brand new tracker -never reviewed by security advisers- will be promptly discovered and neutralized but the CONS is represented by the fact that also the most known intrusive tracker will be initially allowed to register your habits.

For its intrinsic features, the Privacy Badger could be added to Firefox as an extra barrier to fight trackers and improve your privacy. In the next post we will examine other add-ons that can be matched with it.
