  • Prettier logging with Rich

    There are a few things going on here. Important fields are rendered in their own column to make it easier to scan. To reduce visual clutter, the time field is only rendered if it changes and I've set the date format to time only, which is fine for local development (if you forget what day it is you need a vacation). The message column has some syntax highlighting applied to it, tuned for web development, but more importantly it is word-wrapped. Finally there is a column for the python file and line that called the log method. This would be my ideal logging for web-development, your mileage may vary and you may want to tune it for your domain.

    We are glad to announce the release of Relatorio version 0.9.1. Relatorio is a templating library mainly for OpenDocument using also OpenDocument as source format.

  • How to write a very simple calculator in Python as a complete beginner programmer

    As I progress with my journey as a computer coder, I have realized that for one to master the art of writing scripts and applications, hours of practice matter more than months of study being spent on How To Program books. Reading theory about computer programming matters, but it does not make one a code writer. Based on such conclusion, I have decided to share real world scenarios materialized in computer code, mostly Python. Through this article you're going to learn how to put in practice basic concepts in Python with the main purpose of pushing your skills to the next level as a doer, instead of just a thinker. Although once finished you will end up with a simple calculator which supports basic maths, at least you will know how to properly make use of builtin utilities such as input, def statements and the while True loop.

As an 'advanced' terminal user, I truly like automating stuff on the console. Before launching a fresh command prompt on your own computer, make sure you meet the requirements shown below in order to follow me through the rest of this blog post.

  • An open source alternative to Internet Download Manager written in Python, pyIDM

    Most of the computer geeks are familiar with the Internet Download Manager tool. Although it is one of the best among download managers; being a soldier of open source software, I decided to share pyIDM as an alternative for anyone who is passionate about computer programming. According to the official documentation shared on the Github platform, pyIDM supports multi-connections at a high speed due to its download engine which relies entirely on LibCurl.

KeePassXC 2.5.3 and Some Tips

  • KeePassXC 2.5.3

    KeePassXC is a community fork of KeePassX, a native cross-platform port of KeePass Password Safe, with the goal to extend and improve it with new features and bugfixes to provide a feature-rich, fully cross-platform and modern open-source password manager. KeePassXC currently uses the KeePass 2.x (.kdbx) password database format as its native file format in versions 3.1 and 4. Database files in version 2 can be opened, but will be upgraded to a newer format. KeePass 1.x (.kdb) databases can be imported into a .kdbx file, but this process is one-way.

  • How to manage your entire passwords with KeePassX, single master key for all of them

    Having many accounts on different social media networks, I have to keep trace of different usernames and passwords. Facebook, Instagram, Pinterest, Twitter and chat applications; different login credentials for each one of them. Not to mention the local accounts. Due to the struggle that comes with remembering all usernames and passwords, and of course due to loss of many important accounts in the past, I have decided to store my entire login credentials in a database which can be accessed through a single master key.

  • How to fully take control of KeePassX through the command line with pykeepass open source python package

    Having needs on secure personal data management, KeePassX is the software which I have chosen to solve my own problem. Being open source, many developers have written their own libraries from scratch to fully interact with KeePassX from the command line. After many hours of research on Github, and a lot of tests on my local environment, pykeepass ended in my toolset. Fully open source and free of charge, this python tool supports interaction with the entire features being integrated on KeePassX; directly from the command line.

Red Hat and IBM: Stronger Now?

  • IBM’s Quarterly Sales Finally Rose—But Not By Much

    IBM’s shares rose by around 5% on January 21 after it said its fourth-quarter revenues had increased by 0.1%, to $21.8 billion, after five quarters in a row of year-over-year sales declines. Big Blue’s fortunes were boosted by a new mainframe product line and revenues from open-source software giant Red Hat, which it acquired in July 2019 for around $34 billion. Adjusted net income for the quarter fell about 5%, to $4.2 billion, while the company reported earnings per share of $4.71 compared with analysts’ consensus estimates of $4.69. IBM saw its full-year 2019 revenue fall 3.1%, to $77.1 billion, and its net income drop by 10%, to $11.4 billion.

  • IBM Sales Expected to Dip Despite Red Hat Purchase: What to Watch

    International Business Machines Corp. is expected to report fourth-quarter earnings after the market closes Tuesday. The technology giant may be heading for its sixth successive quarter of year-over-year revenue decline—but has been trying to reverse that slide, in part, through the $33 billion purchase of open source software giant Red Hat Inc.

  • IBM Earnings Hint at Signs of Turnaround

    International Business Machines Corp. reported a slight increase in quarterly revenue, ending a streak of falling sales and providing a first indication Chief Executive Ginni Rometty’s roughly $33 billion acquisition of open-source software giant Red Hat may help turn around Big Blue’s fortunes.

  • IBM Open Sources SysFlow Monitoring Platform

    Fred Araujo, a research scientist in the Cognitive Cybersecurity Intelligence Group at IBM Research, said IBM developed lightweight SysFlow agent software and monitoring tools as a way to provide more context around the telemetry data being collected while simultaneously reducing the amount of data that needs to be stored. SysFlow encodes a representation of system activities into a compact format that records how applications interact with their environment, Araujo said, noting that level of context provides deeper visibility in everything from container workloads to cybersecurity forensics. However, unlike existing monitoring platforms, SysFlow doesn’t require IT organizations to collect a massive amount of data to achieve that goal—it is intended to provide for a superset of the NetFlow framework used to analyze network traffic patterns to capture system events, he said. Araujo noted IBM doesn’t envision SysFlow eliminating the need for legacy log analytics platforms, as they provide a way to analyze log data. However, SysFlow does enable IT organizations to apply analytics via a graph-like visualization to surface patterns that goes beyond a comparative simple rules-based approach, said Araujo. For example, SysFlow’s approach will make it easier to uncover the relationship between various events that make up a cybersecurity attack and subsequently to identify what countermeasures to employ to create the appropriate kill chain response. It also should substantially reduce the amount of fatigue cybersecurity teams experience from chasing down false-positive alerts, he said.

  • Open source principles key to digital transformation

    The book outlines how open source principles can be used to build a better business by powering the transformation of not only technology, but also culture and business practices. However, there is no single understanding of exactly what digital transformation is. Most people recognise that the world has changed with digital devices and services connecting everything and everyone, and customers have more choice than ever before. As a result, every industry faces disruption and businesses have to change – transform – if they are to meet new consumer demands and stay ahead of the competition.

Internet Wars: Microsoft EEE Against Mozilla's Rust, Moving From Chrome to Mozilla Firefox, Cake PR and Microsoft Still Playing Dirty

  • Developers love Rust programming language: Here's why

    In fact, Rust has been voted the most-loved language for the past four years in Stack Overflow's annual developer surveys, even though 97% of respondents haven't used it. So how has it become the most-loved programming language? "The short answer is that Rust solves pain points present in many other languages, providing a solid step forward with a limited number of downsides," explains Jake Goulding on Stack Overflow's blog. [...] Mozilla Research describes Rust as a "systems programming language that focuses on speed, memory safety, and parallelism". It's often seen as an alternative to systems programming languages like C and C++ that developers use to create game engines, operating systems, file systems, browser components, and VR simulation engines. Mozilla, which continues to sponsor the project, says programmers can use Rust to make software that's less prone to bugs and attacks.

  • I finally switched from Chrome to Mozilla Firefox — and you should too

    I have been in an on-and-off relationship with Mozilla Firefox for the past five years. Every time I’d get ecstatic over a major new Firefox update — hoping to, at long last, break free from the hegemony of Google Chrome — my hopes would be crushed as soon as I began browsing the web like I normally do. Firefox’s performance would fall noticeably short and struggle to keep up with my workflow, sending me scurrying back to Google Chrome after a few minutes of poking around. No matter how compelling the rest of Mozilla’s offerings were, they could never convince me to hit that “Yes” button whenever Firefox asked whether I’d like to set it as my default browser. Catching up to Chrome almost started to seem like a far-fetched goal for Firefox — until recently. [...] Today, in addition to being fast, Firefox is resource-efficient, unlike most of its peers. I don’t have to think twice before firing up yet another tab. It’s rare that I’m forced to close an existing tab to make room for a new one. On Firefox, my 2015 MacBook Pro’s fans don’t blast past my noise-canceling headphones, which happened fairly regularly on Chrome as it pushed my laptop’s fans to their helicopter-like limits to keep things running. This rare balance of efficiency and performance is the result of the countless under-the-hood upgrades Firefox has rolled out in the last couple of years. One of the recent major performance updates arrived in May when Mozilla natively integrated a handful of clever optimizations for which users previously had to rely on third-party extensions.

  • Passive aggressive baking at its finest

    Cakes are a long standing weapon in the browser wars. Whenever a major browser hits a new milestone or makes an important release, cakes are rapidly exchanged.

  • Microsoft will never win the search engine wars by forcing people to use Bing

    Bing is known as the default search engine for Windows, and not much else. Microsoft’s solution? To forcibly install a Bing search extension in Chrome for Office 365 ProPlus users. The company says that this is designed for enterprise and business users to find relevant workplace information directly from the browser address bar, but we all know Microsoft is desperate to get more people using its search engine. It sounds harmless, but here’s why forcing people to use Bing won’t help Microsoft in the long run. [...] Fast forward to today, Bing still has a few problems that need to be addressed, and where Microsoft should put some extra attention towards, instead of forcing Bing down people’s throats. These include both search relevance and design — the two core areas of any search engine. First of all, there is a search relevance. In our testing, searching for Digital Trends on Google and Bing provide two different results. On Bing, we get a look at some older Digital Trends articles, which at the time of this writing, were older stories from 4, 6, and 3 hours ago. Compared that to Google, and articles are more relevant pulled from a most recent time frame.
