Ubuntu OS Optimization Tips

You can improve the performance of your computer by following some simple tips. Some of these tips include Preloading, Hibernation, Uninstalling applications, and optimizing memory usage. Using the tips in this article can help you improve the performance of your Ubuntu OS. It is also a good idea to learn about the Linux kernel compilation process.

Preload

Ubuntu is a fast operating system by default, but you may have noticed that some applications take a long time to start. If you’d like to speed up the start-up of such applications, use the Preload application. It runs in the background and analyzes user behavior. It then fetches the binaries and dependencies that will make applications start faster.

Preload works similarly to Windows Vista’s Superfetch. It optimizes startup time by monitoring which applications you use frequently and caching these in memory. It works best on computers with a large amount of memory. Besides accelerating startup times, it can also free up more memory for new applications.

Hibernation

Hibernation is a useful feature that enables your computer to save memory during periods of inactivity. It works by turning off all the programs, saving RAM data into the swap partition. However, this feature requires that your system’s swap partition is larger than your RAM. The size of this swap file determines whether your computer will enter hibernation or not.

After you reboot your system, you can verify whether your system is in hibernation mode. The hibernate command should return “yes.” If the command does not work, follow the troubleshooting instructions in the next section.

Optimizing memory usage

If you’re having problems with the memory usage on your Ubuntu OS system, you should consider optimizing your memory settings. This will help you save valuable memory. For instance, you should avoid running processes that aren’t necessary. Similarly, you should not store unused data in the memory of your computer. This will prevent your system from overworking its memory and crashing. It will also save your team both time and frustration.

The type of programs you’re using can affect how much memory you’re using. While most programs are linked to the default LibC, there are several alternatives that can significantly reduce memory usage. For example, dietlibc and uClibc are both good options for developers. These libraries are smaller and use less memory. For best performance, dynamically linking your code and removing any debug information can also help you reduce memory usage.

Swap partition

If you’d like to use the Swap partition for temporary data storage, there are a couple of steps you can take to do so. First, you need to open a terminal and log in as an administrator. Next, you need to change the value of the swappiness variable. This value can range from 0 to 100. By setting the value to 20 or 60, you’ll instruct Linux to move processes to this location when memory usage reaches 80% or 40%.

The swap partition in Ubuntu OS optimization tips can help you make better use of the system’s storage space. By setting up the swap partition correctly, you can make your computer run faster. In addition, it will free up additional disk space, which can increase the overall performance of your machine. But before you can partition SWAP, you need to make sure that you don’t have any applications running. You can also use the free and top commands to see how much space is allocated to swap. And if you want to check the swap status, run fdisk and make sure that it’s running in run level one or single user mode. You can also run fdisk to see the existing partitions on your hard drive and the partition tables for each drive. This command is interactive and only works on the disk drive you specify.https://www.youtube.com/embed/Inj3v_D61ME

Coronavirus: should patients be geolocated via their smartphones?

Israel and China rely on state surveillance tools to fight against the spread of the virus. Other countries are exploring mobile geolocation voluntarily.

Faced with the spread of Covid-19, the Israeli government has taken the radical step of geolocating coronavirus patients as well as those who could be. A government decree has just decided this surveillance and has been entrusted to Shin Bet, the internal intelligence service. The latter intends to rely on ‘advanced technologies generally used in the fight against terrorism,’ explains the daily Haaretz. The aim is to monitor the progress of the disease, to alert people who may have come into contact with a carrier of the virus, and to enforce a quarantine on a case-by-case basis.

Aware that this is a significant intrusion into the privacy of users, the Israeli government specifies in its law that the data collected cannot be used for any purpose other than health and will be erased at the end of the epidemic. Moreover, e-mails and SMS messages would not be monitored. We are reassured.

With this measure, the State of Israel is following in the footsteps of China, which is not only geolocating the sick but also carrying out a probabilistic diagnosis. As a New York Times article showed, every citizen has a mobile application that records movements and displays the risk of having been contaminated using a color code that must be shown to the police. If the result is red, you’re stuck.

In South Korea, mobile applications are also used to geolocate patients, but voluntarily. With apps such as “Corona 100m”, “Corona Doctor” or “Corona Map,” users can see if there are many positive cases in the vicinity and thus adapt their behavior.

These countries are not the only ones looking into mobile geolocation. In Germany, the Hanover Medical University is working with the start-up Ubilabs to develop GeoHealth, a mobile application that, like Chinese software, records movements and indicates the level of risk with color-coding. The head of the Robert Koch Institute of Epidemiology fully endorses this approach, as he believes it would make it possible to combat the spread of the virus better.

In the United States, several projects are emerging. That is the case, for example, of the CoEpi and MIT/Private Kit projects. All these initiatives raise many questions. Who collects the data, and how is it stored? How can we be sure that they are not used for something else? And then, is it efficient?

Indeed, mobile geolocation has, at best, the accuracy of only about ten meters, whereas the coronavirus does not spread beyond a few meters. It is also challenging to take into account all the previous passages of potential patients who could have soiled an object in the surrounding area. But this track seems nevertheless interesting, provided that you don’t think you are Big Brother.

iPadOS has arrived: are are some of new features!

Since the invention of the iPad 10 years ago, the creation of this tablet around iOS has given Apple a head start in terms of performance and ergonomics.

It is almost the end of 2019; Apple introduced iPadOS, an OS dedicated to its iPad. This major update of the iPad is a bit like a third-platform that combines the popular ideas of macOS with the intuitive nature of iOS.

What is iPadOS?

iPadOS is iOS 13, but iOS 13 is not iPad OS. Did you follow it? More simply, Apple has decided to name the OS of its iPad differently from the OS of its iPhone even if both operating systems use the same code base. iPadOS is surely a sign of Apple’s desire to make the iPad sacred as a laptop inspired by the Mac but based on iOS.

What are the main new features of iPadOS?

iPadOS takes advantage of the new features of iOS 13, including the long-awaited dark mode and the redesign of native applications (Reminders, Notes, etc.). But there are some remarkable new features on iPadOS.

These include file management, multitasking, and the integration of external hardware. You can also visit the folder dedicated to the hidden features of iOS 13, many of which you will find on iPadOS.

You can connect external devices such as USB sticks

The iPadOS Files application is another excellent example of how macOS ideas can be integrated with a new design and modern interactions that make sense on iPad. This application has become very practical, especially since Apple has opened access to external USB sticks and SD cards.

Safari has become a desktop web browser

Safari for iPad now defaults to Safari for Mac on all iPad models. You have access to the same websites on your PC or Mac. It’s very convenient, especially for Google Docs, Gmail and lots of web services.

Ipados supports mice and new keyboard shortcuts with more than 30 new shortcuts corresponding to almost all the options available on macOS.

Multitasking is extended

Since iOS 11, it is possible to open two applications simultaneously on iPad Pro. iPadOS goes further: it is now possible to open the same app several times on the entire system. Apple calls them “windows”, like on macOS and Windows. Even if they don’t look like windows as we know them – there is no underlying desktop, and the windows can’t overlap (except for Slide Over) – they behave in much the same way.

To encourage users to use multi-window technology, Apple has chosen to adapt to iOS 11’s drag-and-drop multitasking to introduce different ways to create application windows. More simply, anything that can be moved in iPadOS can become its own window. On Safari, if you want to open a link in a new window, simply move the link.

Force Touch is here

As on iOS 13, Force Touch is everywhere, even on devices that were not compatible with it. The iPad, therefore, inherits Force Touch.

A long press on the icons and various elements opens a menu, like the right click of a mouse. Moreover, you have access to quick actions on the home screen.
