  • 9 Reasons You Should Use Golang Language

    Golang is the open-source programming language developed by Google in the year 2007. Several programming languages are present in the market with advantages and disadvantages. We cannot predict which language is better, it would take months to discuss. However, the most sensible thing that helps choose a better language is the one that suits a specific purpose more reliably than the others. Thus, Golang development will be most suitable for those who are willing to combine simplicity, concurrency, and safety of the code.

    Different programming languages are less memory efficient and are unable to communicate with the hardware. Therefore, Golang is one of the most preferred languages for developers that help build software. It is also the open-source and procedural language that is advantageous to deploy simple, effective, and reliable software. Go language aids the environment to adopt different patterns that are similar to dynamic languages.

    Go language has several advantages that are responsible to quicken the development process. Moreover, Golang is the language that makes the process of software development easy and simple for programmers. These days, Golang is gaining popularity amongst the developers as it has a plethora of advantages than the other programming languages. So, the use of Golang has been adopted by mobile app development companies.

  • Demonstrating PERL with Tic-Tac-Toe, Part 1

    PERL is a procedural programming language. A program written in PERL consists of a series of commands that are executed sequentially. With few exceptions, most commands alter the state of the computer’s memory in some way.

    Line 00 in the Tic-Tac-Toe program isn’t technically part of the PERL program and it can be omitted. It is called a shebang (the letter e is pronounced soft as it is in the word shell). The purpose of the shebang line is to tell the operating system what interpreter the remaining text should be processed with if one isn’t specified on the command line.

    Line 02 isn’t strictly necessary for this program either. It makes available an advanced command named state. The state command creates a variable that can retain its value after it has gone out of scope. I’m using it here as a way to avoid declaring a global variable. It is considered good practice in computer programming to avoid using global variables where possible because they allow for action at a distance. If you didn’t follow all of that, don’t worry about it. It’s not important at this point.

  • Perl Weekly Challenge 048: Survivor and Palindrome Dates

    I tried two different approaches to the problem.

    The first one uses an array of living people and a variable $sword that stores the index of the person holding the sword. In each iteration of the loop, the next person is removed from the array, and the sword is passed to the next person.

    The “next person” has a special cyclic meaning: at the end of the array, the sword must return to the beginning. This is achieved by using the modulo operator %. Note that we use it twice, once to find the person to kill, and once to find the person to pass the sword to—and each case uses a different array size in the modulo operation, as killing a person changes the size of the array.

  • My Unexpected Dive into Open-Source Python

    I'm very happy to announce that I have joined Quansight as a front-end developer and designer! It was a happy coincidence how I joined- the intersection of my skills and the open source community's expanded vision.

    I met Ralf Gommers, the director of Quansight Labs, at the PyData Conference in New York City last year after giving a Lightning Talk. However, as cool and confident as this may sound, I sure didn't start off that way.

    At that point, it's been a few months since I graduated from a coding bootcamp. I was feeling down in the job-search funk. I hadn't even done much in Python, since my focus was in Javascript.

  • Reposurgeon defeats all monsters!

    On January 12th 2020, reposurgeon performed a successful conversion of its biggest repository ever – the entire history of the GNU Compiler Collection, 280K commits with a history stretching back through 1987. Not only were some parts CVS, the earliest portions predated CVS and had been stored in RCS.

    I waited this long to talk about it to give the dust time to settle on the conversion. But it’s been 5 weeks now and I’ve heard nary a peep from the GCC developers about any problems, so I think we can score this as reposurgeon’s biggest victory yet.

    The Go port really proved itself. Those 280K commits can be handled on the 128GB Great Beast with a load time of about two hours. I have to tell the Go garbage collector to be really aggressive – set GOGC=30 – but that’s exactly what GOGC is for.

This is a different kind of video because it has a bit of Time Travel in it. In June 2019, I presented a talk at the SouthEast LinuxFest entitled “Kdenlive: From Beginner to Advanced Video Editing”. This was an interesting experience and the editing process took an excessive amount of time which I suppose is fitting for a video about video editing. In this video, you will learn some tips and tricks that I use for working in Kdenlive as well as some cool transitions like Matte Transitions. There was also a very useful Questions & Answers section at the end of the talk.

I actually learned some more things during the process of editing this video so there is always plenty to learn about this kind of software. If you would like more Kdenlive videos from me then please leave a comment below. I would be happy to make some specific tutorial videos, this is more of an overview and I think there’s plenty to show in tutorial form.

    In this episode, we added content to a template and talked about the N+1 query bug. I also worked tricky logic involving date handling.

    The first change was to update a course page to include a new icon for any course task that should be graded. After adding this, we hit an N+1 query bug, which is a performance bug that happens when code queries a database in a loop. We talked about why this happens and how to fix it.

    After finishing that issue, we switched gears and worked on a tricky logic bug. I need a daily view to fetch data and factor in the relative time shift between the selected day and today. We wrote an involved test to simulate the right conditions and then fixed the code to handle the date shift properly.

KVM and Xen Project: Commercial Exploitation and Unikraft Work

  • Cloud, Linux vendors cash in on KVM-based virtualization

    Vendors such as Red Hat, IBM, Canonical and Google rely on KVM-based virtualization technology for many of their virtualization products because it enables IT administrators to execute multiple OSes on the same hardware. As a result, it has become a staple in IT admins' virtual systems.

    KVM was first announced in October 2006 and was added to the mainline Linux kernel in February 2007, which means that if admins are running a Linux machine, they can run KVM out of the box.

    KVM is a Type 1 hypervisor, which means that each individual VM acts similar to a regular Linux process and allocates resources accordingly. Other Type 1 hypervisors include Citrix XenServer, Microsoft Hyper-V, Oracle VM Server for x86 and VMware ESXi.

  • Unikraft: Building Powerful Unikernels Has Never Been Easier!

    Two years ago, the Xen Project introduced Unikraft (http://unikraft.org) as an incubation project. Over the past two years, the Unikraft project has seen some great momentum. Since the last release, the community has grown about 20% and contributions have diversified a great deal. Contributions from outside the project founders (NEC) now make up 63% of all contributions, up from about 25% this time last year! In addition, a total of 56,739 lines were added since the last release (0.3).

    [...]

    Finally, the Unikraft team’s Simon Kuenzer recently gave a talk at FOSDEM titled “Unikraft: A Unikernel Toolkit”. Simon, a senior systems researcher at NEC Labs and the lead maintainer of Unikraft, spoke all about Unikraft and provided a comprehensive overview of the project, where it’s been and what’s in store.

Gopher: When Adversarial Interoperability Burrowed Under the Gatekeepers' Fortresses

Filed under
Web

In the early 1990s, personal computers did not arrive in an "Internet-ready" state. Before students could connect their systems to UMN's network, they needed to install basic networking software that allowed their computers to communicate over TCP/IP, as well as dial-up software for protocols like PPP or SLIP. Some computers needed network cards or modems, and their associated drivers.

That was just for starters. Once the students' systems were ready to connect to the Internet, they still needed the basic tools for accessing distant servers: FTP software, a Usenet reader, a terminal emulator, and an email client, all crammed onto a floppy disk (or two). The task of marshalling, distributing, and supporting these tools fell to the university's Microcomputer Center.

For the university, the need to get students these basic tools was a blessing and a curse. It was labor-intensive work, sure, but it also meant that the Microcomputer Center could ensure that the students' newly Internet-ready computers were also configured to access the campus network and its resources, saving the Microcomputer Center thousands of hours talking students through the configuration process. It also meant that the Microcomputer Center could act like a mini App Store, starting students out on their online journeys with a curated collection of up-to-date, reliable tools.

That's where Gopher comes in. While the campus mainframe administrators had plans to selectively connect their systems to the Internet through specialized software, the Microcomputer Center had different ideas. Years before the public had heard of the World Wide Web, the Gopher team sought to fill the same niche, by connecting disparate systems to the Internet and making them available to those with little-to-no technical expertise—with or without the cooperation of the systems they were connecting.

Gopher used text-based menus to navigate "Gopherspace" (all the world's public Gopher servers). The Microcomputer Center team created Gopher clients that ran on Macs, DOS, and in Unix-based terminals. The original Gopher servers were a motley assortment of used Macintosh IIci systems running A/UX, Apple's flavor of Unix. The team also had access to several NeXT workstations.

  • Network Automation: Why organizations shouldn’t wait to get started

    For many enterprises, we don’t need to sing the praises of IT automation - they already get it. They understand the value of automation, have invested in a platform and strategy, and have seen first-hand the benefits IT automation can deliver. However, unlike IT automation, according to a new report from Forrester Research 1, network automation is still new territory for many organizations.

    The report, "Jump-Start Your Network Automation," found that 56% of global infrastructure technology decision makers have implemented/are implementing or are expanding/upgrading their implementation of automation software, while another 19% plan to implement it over the next 12 months. But those same organizations that are embracing IT automation haven’t necessarily been able to take that same initiative when it comes to automating their networks.

    Even if they know it will be beneficial to them, the report found that organizations often struggle with even the most basic questions around automating their networks.

  • Using a story’s theme to inform the filmmaking: Farming for the Future

As a self-proclaimed city boy, I was intrigued by my assignment as director of the short documentary, but also felt like the subject matter was worlds away. If it did, in fact, belong to all of us how would we convey this to a general audience? How could we use the film’s theme to inform how we might approach the filmmaking to enhance the storytelling?

  • Introduction to open data sets and the importance of metadata

    More data is becoming freely available through initiatives such as institutions and research publications requiring that data sets be freely available along with the publications that refer to them. For example, Nature magazine instituted a policy for authors to declare how the data behind their published research can be accessed by interested readers.

    To make it easier for tools to find out what’s in a data set, authors, researchers, and suppliers of data sets are being encouraged to add metadata to their data sets. There are various forms for metadata that data sets use. For example, the US Government data.gov site uses the standard DCAT-US Schema v1.1 whereas the Google Dataset Search tool relies mostly on schema.org tagging. However, many data sets have no metadata at all. That’s why you won’t find all open data sets through search, and you need to go to known portals and explore if portals exist in the region, city, or topic of your interest. If you are deeply curious about metadata, you can see the alignment between DCAT and schema.org in the DCAT specification dated February 2020. The data sets themselves come in various forms for download, such as CSV, JSON, GeoJSON, and .zip. Sometimes data sets can be accessed through APIs.

    Another way that data sets are becoming available is through government initiatives to make data available. In the US, data.gov has more than 250,000 data sets available for developers to use. A similar initiative in India, data.gov.in, has more than 350,000 resources available.

    Companies like IBM sometimes provide access to data, like weather data, or give tips on how to process freely available data. For example, an introduction to NOAA weather data for JFK Airport is used to train the open source Model Asset eXchange Weather Forecaster (you can see the model artifacts on GitHub).

    When developing a prototype or training a model during a hackathon, it’s great to have access to relevant data to make your solution more convincing. There are many public data sets available to get you started. I’ll go over some of the ways to find them and provide access considerations. Note that some of the data sets might require some pre-processing before they can be used, for example, to handle missing data, but for a hackathon, they are often good enough.

  • Chrome deploys deep-linking tech in latest browser build despite privacy concerns

    Google has implemented a browser capability in Chrome called ScrollToTextFragment that enables deep links to web documents, but it has done so despite unresolved privacy concerns and lack of support from other browser makers.

    Via Twitter on Tuesday, Peter Snyder, privacy researcher at privacy-focused browser maker Brave Software, observed that ScrollToTextFragment shipped earlier this month in Chrome 80 unflagged, meaning it's active, despite privacy issues that have been raised.

    "Imposing privacy and security leaks to existing sites (many of which will never be updated) REALLY should be a 'don't break the web,' never-cross redline," he wrote. "This spec does that."

    The debate over the feature percolated last year on mailing lists and in GitHub issues posts and picked up in October when the team working on Chrome's Blink engine declared their intent to implement the specification. The feature rollout serves to illustrate that the consensus-based web standards process doesn't do much to constrain the technology Google deploys.

    Gentoo provides one of the best frameworks for providing Python support in packages among operating systems. This includes support for running multiple versions of Python (while most other distributions avoid going beyond simultaneous support for Python 2 and one version of Python 3), alternative implementations of Python, reliable tests, deep QA checks. While we aim to keep things simple, this is not always possible.

    At the same time, the available documentation is limited and not always up-to-date. Both the built-in eclass documentation and Python project wiki page provide bits of documentation but they are mostly in reference form and not very suitable for beginners nor people who do not actively follow the developments within the ecosystem. This results in suboptimal ebuilds, improper dependencies, missing tests.

Today this chymera is disappearing for real, and python-single-r1 are going to use PYTHON_SINGLE_TARGET flags only.

    Ultimate Chicken Horse, a party-platform where you build the platforms as you go is getting a sweet free update with some new toys to play with next month. A game you absolutely need to play too! After only just getting into it myself thanks to the Humble Sweet Farm Bundle last month, it was pretty hilarious to try. Clever Endeavour Games have now announced the "A·cobra·tic Update" which is due out on March 12, for all platforms and it's free. It's going to include a new Snake character (who rides a Skateboard), two new levels and four new blocks. Along with "a handful of improvements, minor additions to the game, and plenty of bug fixes". The new blocks flamethrower, one-way gate, cannon and beehive sound like they will be fun to screw with others.

  • Dota Underlords from Valve is out with the City Crawl campaign mode

    Valve's latest game, Dota Underlords, has today left Early Access and with it comes a huge patch full of new content and features. The biggest addition to the Underlords strategy game is the City Crawl campaign. A single-player mode, that explains a bit about what's going on. It seems "Mama Eeb" passed away, leaving a power vacuum in White Spire, with the four Underlords attempting to take control. City Crawl is where you do that, as you go through various different types of challenges and while doing so earn new outfits for the Underlords.
