expo unexpected token '?' no stack

Domingos Manuel Capitango — Fri, 23 Apr 2021 07:26:42 +0000

Try to run:
expo r -c

Setting a timer for a long period of time, i.e. multiple minutes, is a performance and correctness issue on Android...

Domingos Manuel Capitango — Sat, 28 Nov 2020 11:13:59 +0000

I also had this bug, I was investigating, and then I came up with the solution that using expo will not solve, however, it can be hidden.

Write this code snippet in the scope of your component, after the imports:

LogBox.ignoreLogs(["Setting a timer"]);
const _console = _.clone(console);
console.warn = (message: string) => {
if (message.indexOf("Setting a timer") <= -1) {
_console.warn(message);
}
};

Windows Phone

Benefits

Confidence

Microsoft values application quality. You have certainly heard that applications in the system store are scarce. To some extent, this has its logic there, especially when compared to the Apple store, but the vast majority of famous apps are already present there. But what we need to take into account is the quality of the applications present there.

Programmers (developers) may take a while to make applications available to the WP, but when they do ... they are practically perfect! They almost never crash and, according to Microsoft, pass tests and receive encryption so they never transmit malicious files to your phone. It is obvious that that app that is in fashion and that is very cool is missing, but it is better to have it later safely, than to have it on time with instabilities and / or serious errors. Of course, that doesn't always happen, but it's not uncommon to see buggy apps on Android, for example.

System updates are also a super plus for Microsoft. Updates are critical to cell phone security. We are bombarded daily by virtual threats and only updates developed by the OS developer can protect us. Microsoft values this and during the update cycle of the different versions of its system, periodically sends updates to its customers.

Disadvantages

Lack of apps

What can be an advantage can also be a disadvantage. It is true that the delay in liberalizing applications for the platform is due, in large part, to the excessive testing carried out by Microsoft. This undoubtedly guarantees the safety of customers, but leaves many with immense dissatisfaction.

Tests could be done more quickly. Microsoft could also invest more in programmers (developers). Apple, for example, spends billions on its apps and its developers. This guarantees your store the highest revenue among operating system stores. Investment never hurts, so investing in your app store would be a great move for Microsoft.

The use of "generic" apps leaves many users dissatisfied. This, by the way, has been the main reason for abandoning the platform.

High cost

Missing or limited notification bar:
The notification bar is already present in version 8.1 of Windows Phone, but in previous versions of the system it is not yet available. If you have a smartphone in this version of the system, you may notice that there is no option to delete a particular notification. Either delete them all, or leave them all. Perhaps this will be resolved in the future, but for now it is an inconvenient problem for many users, especially those coming from the Android system. It is already an evolution, of course, but it needs to be improved. If you have Windows Phone 8 or lower, unfortunately you will not have a notification bar and you will have to be content to search for your notifications going from application to application.

Android

Benefits

Open operating system;
Works lightly with devices with more hardware;
It has sensitive touch in analysis to other old devices;
Free apps on the Android Market;
Connection to social networks;
Internet connection;
Cheaper handsets at operators;

Disadvantages

Paid apps more expensive than in other stores;

Macintosh

Benefits

More stable than Windows.
Better at the Visual level.
Better at the Design level.
Easier and purpose.
Few viruses created for the apple OS.
Suitable for designers, who work with photography, video editing, modeling, 2D / 3D animation.

Disadvantages

Incompatible with many software, especially games, although it is already possible to dualboot with windows.
It only runs on Apple PCs that are still a little expensive, yes there is a hackintosh but the performance is not the same.

Linux

Benefits

Open-Source License (Open Source) - This is the main advantage of Linux, when using an open-source license, it allows it to be used and distributed free of charge, giving also the opportunity to anyone to correct flaws or customize it to your needs. like (something that does not happen with Windows).
Almost total virus immunity - As it is an operating system developed by a group of volunteers worldwide, flaws are quickly detected and corrected. High Performance - No matter how old your computer hardware is, Linux easily adapts to it, reducing unnecessary functionality. As it is a fully customizable operating system, the user can also uninstall all the features and programs that he does not use to save resources. Install and Use - With the arrival of Windows 7 the installation delay time has improved a lot, the problem is that after installation it is necessary to install drivers and other things. In Linux this does not happen, speaking from experience, it took me 30 minutes to install Linux on my PC, and after that it was ready to use, I did not need to install drivers.
Compatibility - Currently Linux is compatible with almost all types of hardware. Linux can either be installed on a small tablet or it can be installed on a powerful MainFrame.

Disadvantages

Programs - Although there are already many alternative programs to those used in Windows that do the same, many are not really useful or are not very intuitive. Games - For those who like to play on the computer Linux is a bad idea since most games for Windows are not compatible with Linux.

Operating System

Windows

Benefits

Ease of use and efficiency: Windows is simply the easiest computer system to organize. Users can perform their respective tasks without too many complications, because Microsoft has made and makes sure to keep everything well organized. Thus, the user tends to be loyal to the brand. However, it is not only the ease that exists in Windows, the system still has the performance of advanced tasks, it has several extremely professional resources that help very well all types of consumers, from those who use the PC for casual use to the advanced ones. That is, combining these two fundamental characteristics, Windows has become a major reference in the world. Microsoft, which is the founding company of Windows, even took advantage of the system's success to migrate to other modalities in the computer world, such as office software and the mobile phone operating system.
Compatibility with different software: Program developers have Windows as the main point of consumption for their products. Today there is practically no software that is not compatible with Windows. Unlike other operating systems, which are often not compatible with some programs; but in this case, the developer is responsible, not necessarily the operating system.
Hardware compatibility: Windows is the system that is most compatible with the drivers of most hardware. When you buy a Web Cam, for example, it will not necessarily be compatible with other operating systems, but with Windows it certainly is.

Disadvantages

Security: As Windows is the most used system, hackers started to work hard on its vulnerabilities. In addition to the security holes that Windows had and has, Internet hackers have started to develop malicious tools to infect users' computers. In fact, all the bad guys started working exclusively on Windows, leaving out other systems. Perhaps this is why many security experts recommend using Linux, an open source system that provides security and stability.
Unfortunately Microsoft has not worked and does not work very hard to inhibit actions against hackers and malicious applications as much as possible. The fact is, if you use Windows, know that your security is compromised. The use of a good antivirus and a renewed firewall reduces the chances of infection of your system. Downloading updates can also help protect yourself from viruses, malware and intrusions.
Closed source code: Windows does not provide its source code. Therefore, if there is a failure in it, only technical support can solve the problem; with that, the risks can be even greater.
Price: Windows is not free, on the contrary, the system costs a lot of money and this may be, in addition to the fact that the source code is closed, the main reason why hackers develop malicious applications for Windows.
Well, those are the main advantages and disadvantages of Windows. The purpose of this article is to make you reflect on this famous system, and consequently come to the conclusion if it is advantageous or not to use Windows, good luck.

Why choose a mechanical keyboard

Domingos Manuel Capitango — Mon, 09 Nov 2020 22:08:09 +0000

The first factor that must be taken into account are the switches:

Switches are small pieces that register each time the key is pressed, transmitting an electric pulse and then signing the key.

This process is much faster than using the conventional membrane keyboards that use sheets with lines of contact contacts are superimposed and small layers of membranes with metallic contacts on the inner side come into contact with these sheets when pressing each key.

The switches also gain other aspects such as speed of responses and so on.

They are the main ways of choosing a mechanical keyboard.

BLUE (TACTILE) switches.

Two types of tactile feedback - it is the most recommended for those who play and who type a lot. But it is a bad choice for those who type close to other users because it is very noisy.

BROWN (TACTILE) switches.

Second choice for easy adaptation, it is quieter than blue, but still maintaining the standard of a traditional mechanical mechanical keyboard.

RED (LINEAR) switches.

These are for specific types of users. These do not have any type of feedback, and are differentiated by the spring tension and the activation distance.

There are more types of switches, which I will explain in another post.
