Read File

Source: https://linuxhint.com/read-file-golang/

The ability to read files is a building block for any non-trivial program. Hence, all programmers must learn how to read files. The first method when reading any file is opening it. The fundamental skills to read file contents using the Go programming language are discussed in this article.

Golang Array Append

Source: https://linuxhint.com/array-append-golang/

A slice is a flexible and extensible data structure used to store and manage a collection of ordered data. Similar to arrays, we use indexes to access elements in a slice. They also have length and capacity properties. This article discusses how to work with slices and how to add or remove items from a slice.

Golang Time Format

Go allows you to format and parse time out of the box provided by the time package. You can specify your target format using pattern-based layouts using the Format() method. Unlike typical date and time formatting options, go uses a specific layout parameter. How to format time in Golang is discussed in this article.

Golang Time Parse

The Parse() function allows you to parse a formatted date string and return the time value represented by the string. The function takes a layout and a formatted date format as the parameters. It then returns the time value. This article will discuss how to use parse function in Go.

Linux Malware Attacks are Increasing, and Businesses Aren't Ready

ZDNet reports: Cyber criminals are increasingly targeting Linux servers and cloud infrastructure to launch ransomware campaigns, cryptojacking attacks and other illicit activity — and many organisations are leaving themselves open to attacks because Linux infrastructure is misconfigured or poorly managed. Analysis from cybersecurity researchers at VMware warns that malware targeting Linux-based systems is increasing in volume and complexity, while there's also a lack of focus on managing and detecting threats against them. This comes after an increase in the use of enterprises relying on cloud-based services because of the rise of hybrid working, with Linux the most common operating system in these environments. That rise has opened new avenues that cyber criminals can exploit to compromise enterprise networks, as detailed by the research paper, including ransomware and cryptojacking attacks tailored to target Linux servers in environments that might not be as strictly monitored as those running Windows. These attacks are designed for maximum impact, as the cyber criminals look to compromise as much as the network as possible before triggering the encryption process and ultimately demanding a ransom for the decryption key. The report warns that ransomware has evolved to target Linux host images used to spin up workloads in virtualised environments, enabling the attackers to simultaneously encrypt vast swathes of the network and make incident response more difficult. The attacks on cloud environments also result in attackers stealing information from servers, which they threaten to publish if they're not paid a ransom.... Cryptojacking and other malware attacks are also increasingly targeting Linux servers. Cryptojacking malware steals processing power from CPUs and servers in order to mine for cryptocurrency.... Many of the cyberattacks targeting Linux environments are still relatively unsophisticated when compared with equivalent attacks targeting Windows systems — that means that with the correct approach to monitoring and securing Linux-based systems, many of these attacks can be prevented. That includes cybersecurity hygiene procedures such as ensuring default passwords aren't in use and avoiding sharing one account across multiple users.

Intel Thread Director Is Headed to Linux for a Major Boost in Alder Lake Performance

Source: https://linux.slashdot.org/story/22/02/12/2237234/intel-thread-director-is-headed-to-linux-for-a-major-boost-in-alder-lake-performance?utm_source=atom1.0mainlinkanon&utm_medium=feed

The Linux 5.18 kernel is adding support this spring for the Intel Hardware Feedback Interface to make better decisions about where to place given work among available CPU cores/threads, reports Phoronix. This is significant because Intel's Alder Lake CPUs "are the first x86-64 processors to embrace a hybrid paradigm with two separate CPU architectures on the same die," explains Hot Hardware: These two separate CPU architectures have different strengths and capabilities. The Golden Cove "performance cores" (or P-cores) feature Intel's latest high-performance desktop CPU architecture, and they are blisteringly fast. Meanwhile, the Gracemont "efficiency cores" (or E-cores) are so small that four of them, along with 2MB of shared L2 cache, can nearly fit in the same space as a single Golden Cove core. They're slower than the Golden Cove cores, but also much more efficient, at least in theory. The idea is that background tasks and light workloads can be run on the E-cores, saving power, while latency-sensitive and compute-intensive tasks can be run on the faster P-cores. The benefits of this may not have been exactly as clear as Intel would have liked on Windows, but they were even less visible on Linux. That's because Linux isn't aware of the unusual configuration of Alder Lake CPUs. Well, that's changing in Linux 5.18, slated for release this spring. Linux 5.18 is bringing support for the Intel Enhanced Hardware Feedback Interface, or EHFI... This is essentially the crux of Intel's "Thread Director," which is an intelligent, low-latency hardware-assisted scheduler.

Valve's Steam Deck Will Run Linux-Based Steam OS - But Won't Have a Fortnite Port

Liliputing reports: When Valve's Steam Deck begins shipping to customers later this month, the handheld gaming PC will be running a Linux-based operating system called Steam OS. And that could give gaming on Linux a bit of a boost. While Valve's game client has been able to run on Linux for years, as of last month just over 1% of Steam users were running Linux (and fewer than 3% were using macOS, with Windows holding a 96% share). It'll be interesting to see if that starts to change once the Steam Deck hits the streets. And if it does, maybe we'll see more game makers add support for Linux... but one of the most popular games around isn't going to add Linux support anytime soon: Epic CEO Tim Sweeney says the company has no plans to port Fortnite to Linux. He says it's because Epic doesn't "have confidence that we'd be able to combat cheating at scale under a wide array of kernel configurations including custom ones," but it's an interesting take since Epic has already ported its anti-cheat software to support Mac and Linux devices including the Steam Deck.

Golang Append

Posted: 2022-02-12 18:53:52
Source: https://linuxhint.com/golang-append/

The append method in go allows you to add any number of specified items to the end of a slice. If there is not enough capacity to hold the specified elements, go creates a new underlying array and copies the existing data to the new array. Keep in mind that the append function does not affect the slice in-place. Golang Append function is discussed in this article.

Golang Anonymous Function

An anonymous refers to a function that does not have a name. This type of function is also known as a function literal or a lambda function in other programming languages. Go allows you to create in-line or anonymous functions for short-term use as we will show in this article.

Golang Anonymous Struct

An anonymous struct is a structure that does not have a name. This means we cannot reference the structure elsewhere in the code. Anonymous structures allow you to define ephemeral structures for one-time use. This article will cover how to create anonymous structures and implement anonymous fields in Go structure.
