New in calibre 4.0

Welcome back, calibre users. It has been two years since calibre 3.0. This time has been spent mostly in making the calibre Content server ever more capable as well as migrating calibre itself from Qt WebKit to Qt WebEngine, because the former is no longer maintained.

The Content server has gained the ability to Edit metadata, Add/remove books and even Convert books to and from all the formats calibre itself supports. It is now a full fledged interface to your calibre libraries.

The change to use Qt WebEngine has entailed a complete rewrite of various parts of calibre, including the E-book Viewer, PDF Output, Book details etc. Every attempt has been made to preserve features and functionality in a backwards compatible way, see below for a list of some known incompatibilities.

Wow, Calibre 4.0 is comming. I can not image how different it is from 3.x.

Calibre 3.48

 

I can wait to see it. Now download it 115MB. Install it. Then launch it.

5 Essential Graphic Design Skills You Should Master

Maybe you’re a contract graphic designer doing small, one-off projects for local businesses. Or, an in-house professional responsible for overseeing all graphic creation in a large corporation. Regardless, you can always be improving your craft. 

Read on as we go over a few more advanced graphic design skills that will substantially improve your ability to communicate your message in the medium.

1. User Interface Design

At first glance, you might think this doesn’t apply to you. Perhaps your work focuses on something where ‘user interfaces’ seem worlds away from your final product. 

Consider this; regardless of what your final product is, the odds of it ending up within a user interface are virtually guaranteed. If you make a graphic for an article header for a local newspaper, for example, that graphic will likely end up in the online version of the publication.

And like it or not, that makes it a part of the user interface of the website. 

Knowing how to design with that type of presentation in mind already makes this a useful skill. Designing user interfaces directly, meanwhile, makes it substantially more worthwhile since the available pool of work for those who can do both is much larger.

Further, user interface creation is one of the more lucrative ways to apply the skills of a graphic designer. Per Indeed.com, user interface designers make, on average, more than double the income of a traditional graphic designer.

How to Protect Your Smartphone from Online Threats

Every day, hundreds of people have their smartphone hacked, exposing important data like contacts and even credit card details to criminals that prey upon poorly protected phones.

Whenever your phone connects to the internet, it is at risk from hacking by data thieves that target phones in particular, as they contain nearly all of our important information such as passwords, emails and even the login details to online banking apps.

Fortunately, there are a few steps anyone can take to protect their phones from harm and recover their data if their smartphone is damaged or locked my malicious software.

Use a Virtual Private Network App When Connected to Public Wi-Fi

When you are using public Wi-Fi, such as when you are at a hotel or café, your phone is at risk of being hacked by someone else using that network. Some data thieves are known to connect to these networks regularly in order to steal credit card information from shoppers and tourists.

Virtual Private Networks encrypt and conceal your web traffic, even when using a public Wi-Fi network. These services can also be used from home to protect your online shopping and browsing there, giving you extra peace of mind.

Use an App to Securely Back Up All of Your Smartphone’s Data

Sometimes when a phone is hacked, it can suddenly become corrupted and unusable, trapping your files like your phone numbers and personal photographs on the device. There are apps available that can back up data to an online cloud service, but sometimes they can be missing important and more recent files.

If you have data on a damaged or corrupted smartphone, there are services like mobile data recovery by Secure Data Recovery that can recover data from your device, sometimes even if it has been deleted by a hacking program.

Use a Password Manager to Encrypt and Generate Your Passwords

Our passwords are gatekeepers to a lot of our sensitive information such as emails and bank accounts. Too many people rely on using the same password, or maybe two or three, in order to log in to all their different accounts.

Password managers use encryption algorithms to generate complex passwords for you, and store them in a ‘digital safe’ in an app on your phone and online on a secure server. The password manager will auto-complete passwords on all your accounts, or they can be copy-and-pasted from the app to the login form. This means you have only one password to remember, the one that logs you into your password manager, and you can let it safely and securely do the rest.

We keep a large amount of sensitive data on our phones, and not just banking details and contact information. Your phone probably has hundreds of photos of friends and family, as well as pictures from social media accounts. This information needs to be protected, not just from theft, but also from accidents and problems with a smartphone’s components. With a few apps and the help of professionals, anyone can protect the data on their phone, and recover it if the worst happens.

Failed to Read the contents of XML Resource: IDD_SSH_KEY_CHANGE_DIALOG

Dreamweaver 2019 does not connect to SFTP server and you see the “Failed to Read the contents of XML Resource: IDD_SSH_KEY_CHANGE_DIALOG” error.

1) Close the Dreamweaver application.

2) Go to the following location:

Windows: C:\Users\[user name]\AppData\Roaming\Adobe\Dreamweaver CC xxxx\en_US\Configuration
macOS: ~/Library/Application Support/Adobe/Dreamweaver CC xxxx/en_US/Configuration

Here, xxxx is the version of Dreamweaver. For example, if you are using Dreamweaver 2017 running on Windows, then your folder location reads:

C:\Users\[user name]\AppData\Roaming\Adobe\Dreamweaver CC 2017\en_US\Configuration

3) Right-click the ssh_hosts file, and rename this file. For example, ssh_hosts_old.

4) Relaunch Dreamweaver and connect to your SFTP server.
