  • How Union Organizers Will Continue Their Fight With Amazon
    Sonntag 19:34 EditorDavid at Slashdot
    „The lopsided vote against a union at Amazon’s warehouse in Bessemer, Alabama, was a major disappointment to organized labor…“ writes the New York Times. „Yet the defeat doesn’t mark the end of the campaign against Amazon so much as a shift in strategy.“ The article notes unions and other labor groups enjoyed more success when opposing Amazon’s plans for a New York headquarters by joining with local politicians and nonprofit organizations: In interviews, labor leaders said they would step up their informal efforts to highlight and resist the company’s business and labor practices rather than …
  • Astronomers Detect a Bright-Blue Bridge of Stars, and It's About To Blow
    Sonntag 18:34 EditorDavid at Slashdot
    „Astrophysicists have found a new region of the Milky Way, and it’s filled with searingly hot, bright-blue stars that are about to explode,“ writes Live Science (in a report shared by long-time Slashdot reader fahrbot-bot): The researchers were creating the most detailed map yet of the star-flecked spiral arms of our galactic neighborhood with the European Space Agency’s (ESA) Gaia telescope when they discovered the region, which they have named the Cepheus spur, they reported in a new study. Nestled between the Orion Arm — where our solar system is — and the constellation Perseus, the spur is …
  • Building Dark Mode
    Sonntag 18:01 Robin Rendle at Feed
    Like many companies, we have a Hack Week at Sentry. In 2017, we coded an app which blared entrance music for anyone who stepped foot in our office. In 2019, we encouraged folks to be nice on the Internet. Noble causes, sure, but for this year’s Hack Week I was determined to advance a cause near and dear to my cold British heart: dark mode. Little did I know that what started as a minor hack week project would become a major lift that included pantone colors, hex codes, and all sorts of variables.

  • A Programmer Learning List (for Beginners)
    Sonntag 17:22 Michael Snoyman at Feed
    My friend has a son who’s graduating high school soon. He’s been learning some programming and is considering it for his career. He asked me a question I hear often: what should I learn next? When I was first learning to code, I always assumed the answer to „what should I learn next“ would be a new programming technique, a new language, a new library, or something along those lines. As I’ve progressed through my career, and especially as I’ve been on the other side of the interview desk, I’ve changed my tune significantly. My standard response to new programmers is that, in addition to honing …
  • Extended Events: Avoid the XML
    Sonntag 16:56 Grant Fritchey at Feed
    One story I hear over and over goes like this: I tried setting up Extended Events, but then I saw the output was XML so I stopped. Look, I get it. I don’t like XML either. It’s a pain to work with. It’s actively difficult to write queries against it. If there weren’t a ton of ways to avoid the XML, yeah, I would never advocate for Extended Events. However, here we are, I have ten pages of blog posts that at least mention Extended Events. Why? Because I avoid the XML (most of the time). Lots of other people do as well. You can too. Let’s see how.
  • NASA's Mars Helicopter Flight Postponed to No Earlier than This Wednesday
    Sonntag 16:34 EditorDavid at Slashdot
    An anonymous reader shares this announcement from NASA: Based on data from the Ingenuity Mars helicopter that arrived late Friday night, NASA has chosen to reschedule the Ingenuity Mars Helicopter’s first experimental flight to no earlier than April 14 [this Wednesday]. During a high-speed spin test of the rotors on Friday, the command sequence controlling the test ended early due to a „watchdog“ timer expiration. This occurred as it was trying to transition the flight computer from ‚Pre-Flight‘ to ‚Flight‘ mode. The helicopter is safe and healthy and communicated its full telemetry set to Ear …

  • What Is Microbenchmarking?
    Sonntag 16:10 Gaurav Gaur at Feed
    Introduction Optimisation of code is an endless struggle. It is often even hard to produce meaningful metrics using jvm as it is an adaptive virtual machine. The article is a brief introduction to microbenchmarking, why microbenchmark, when to consider it, and finally, pitfalls to avoid What Is a Microbenchmark A microbenchmark is an attempt to measure the performance of a small unit of code. The tests are usually in the sub-millisecond range. The tests can help determine how the code is going to behave when released into production. These tests are guide to a better implementation.
  • SQLiteOpenHelper and Database Inspector in Android
    Sonntag 15:52 Thomas Plathanath Mathew at Feed
    What Is SQLite? SQLite is an open-source relational database, similar to MySQL. Android includes a SQLite library in its standard library that implements a serverless, zero-configuration, and transactional SQL database engine. SQLite does not run on a database server, but stores all its data in simple files. A complete SQLite database with many tables, triggers, indices, and views is contained in a single disk file. SQLite is built into all mobile phones and most computers and comes bundled inside. It carries lightweight data and does not require any administration or setup procedure of the da …
  • Bad Code Reviews Wreck Morale. We Need a Different Outlook
    Sonntag 15:27 Jasper Sprengers at Feed
    I love reviews. When it comes to new gadgets and whether they’re worth my money, it’s a blessing to have so much free advice to guide your choice. Last year I bought a new digital piano online, purely based on internet reviews since retail was locked down and I couldn’t try it out anywhere. Most reviews were favorable to raving, so I found safety in numbers there. Sure, retailers reviewing their own wares are naturally biased, but then again nobody would go to the trouble of a scathing review simply because they don’t like music in general or have it in for Casio as a company. Pianos are not c …
  • Done With A Feature. So What’s Next?
    Sonntag 15:07 Suparna Shaligram at Feed
    Often a scrum team decides to implement a feature in a sprint, codes it and sends it to testing. At this stage, the product owner, scrum master, and the team often get a false impression that the feature is almost done and what remains is just testing and releasing it to production. Right?Wrong! Experience has shown that this only the start. The battle is only half won and there are many hurdles to get that feature to the finish line. Our scrum team went through several sprints where we thought we were ready to release a feature to production but “something” came up towards the end of the spri …
  • Attackers Can Now Remotely Deactivate WhatsApp on Your Phone
    Sonntag 13:04 EditorDavid at Slashdot
    „Using just your phone number, a remote attacker can easily deactivate WhatsApp on your phone and then stop you getting back in,“ reports a new article in Forbes. „Even two-factor authentication will not stop this…“ The attacker triggers a 12-hour freeze on new verification codes being sent to your phone — then simply reports that same phone number as a lost/stolen phone needing deactivation. There are apparently no follow-up questions, and „an automated process has been triggered, without your knowledge, and your account will now be deactivated,“ Forbes writes.

    According to the Microsoft website, a macro is a series of commands that you can use to automate a repeated task and can be run when you must perform the task. The use of macro instructions was originally initiated for assembly language programming to perform two main purposes: to reduce the amount of coding that had to be written by generating several assembly language statements from one macro instruction, and to enforce program writing standards. Nowadays, macros are used for a wide variety of purposes and industries; Microsoft applications currently use Visual Basic for Applications (VBA) …

  • Generating a Hyperlambda Database CRUD backend

If you prefer to watch a video where I demonstrate this process, you can watch the following video. As you can see in the above video, what Magic does for us, is to provide us with a starting point, from where we can modify the code, to have it do whatever we want it to do for us.
