When you design software to achieve a particular level of performance, it can be a good idea to be familiar with the general speed regimes you are working with: fundamental limitations like storage devices and networks can drive software architecture. Here are a set of common benchmark numbers that can help you anchor performance conversations and think about the components that your software will interact with. As with all guidelines, thes..

As I close in on my promotion to captain, mentorship has become an increasingly important part of my job. Many new lieutenants find the Basic Officer Leader Course just that — basic — and so they report eager to develop personally, professionally, and militarily. My article Personal Development addresses that first domain in terms of improving one’s personal, professional, and military knowledge , but neglects other areas. After severa..

So… TL;DR: We lost all of your data created after 28th November 2021 at midnight… No, we probably can't get it back for you… Yes, I am terribly sorry, this affected us as well… a lot… anyway… Matrix data should be mostly recoverable, we hope, except for password resets and new accounts, I suppose… that would have to be recreated… also anything that isn't federated… and perhaps some things that are… Invidious and Plik data from after the dat....

First of all this is not the usual(ess) article that says “use Low Power Mode, disable background refresh, etc…” we already know those stupids tips, I’m assuming that we are a bit above this level. So I would try to explain how to keep charged your batteries between 20% and 80% using Shortcuts and Alexa connected Smart Plug, plus get some notifications when the batteries are below or above a threshold of other devices. For example, get an..

At this point most people are pretty cynical about social media. The worst offender in that space is Facebook , recently rebranded into Meta . In a world constantly incentivized by profit it’s difficult to imagine Meta optimizing for anything else. The striking part was always how cunning and ruthless they are in pursuing profit. Nevertheless, despite many controversies around privacy, usage of personal data and Meta ’s political invol..

Why reaching DDR4's theoretical bandwidth is nearly impossible. CPU parallel reductions struggle to hit 60% saturation while GPU solutions easily exceed 79%.

Back in 2019, I picked up a rare SPARC-based laptop from the 1990s running Solaris UNIX (marketed as the ultimate UNIX portable on the Tadpole website in 1997). You can read my blog post on it here: SPARCbook 3000ST: The coolest 90s laptop . It occasionally shows up on Hacker News, and I get plenty of comments whenever I post it on Reddit.

If you just got started with Zig , you might quickly want to use a hashmap. Zig provides good defaults, with a lot of customization options. Here I will try to guide you into choosing the right hashmap type. 60-second explainer You probably want: var my_hash_map = std . StringHashMap ( V ). init ( allocator ); Or if you do not have string keys, you can use an Auto hashmap instead: var my_hash_m....

How can you can speed up Python? Have you thought of using a JIT (Just-In-Time Compiler)? This week on the show, we have Real Python author and previous guest Anthony Shaw to talk about his project Pyjion, a drop-in JIT compiler for CPython 3.10.

Rails 7 introduced import maps as the new default way to manager javascript. To quote the readme from importmap-rails: Import maps let you import JavaScript modules using logical names that map to versioned/digested files – directly from the browser. So you can build modern JavaScript applications using JavaScript libraries made for ES modules (ESM) without the need for transpiling or bundling . This frees you from needing Webpack, Ya....

A very touching Akhil Sharma in The New Yorker : Not long after we began dating, my now wife, Christine, and I started making up stories about the child we might have. We named the child—or, in the stories we told about him, he named himself—Suzuki Noguchi. Among the things we liked about him was that he was cheerfully indifferent to us. He did not wish to be either Irish (like Christine) or Indian (like me). Suzuki was eight, and....

I started this blog few weeks ago and I installed, despite my will, Google Analytics but, just few days after… G. Analytics has been declared illegal in EU. Then? Okay, first a bit of background: everyone is curious of how many visitors, from where and from which referral site, is coming to his website. And I’m too, so what is the easy to install, free and detailed analytic service? Google Analytics, you bet. Well, maybe it’s true, if you....

I wanted to use Blackblaze's B2 service to host uploads for this site using Active Storage. I wrote this up when I couldn't find a guide to configure the two to work together. B2 advertises itself as the most affordable cloud bucket storage. 🤞 here's to hoping it remains competitively priced. Rails 5.2 introduced Active Storage, a simple way to add attachments in your Rails applications. Rails 6 introduce Action Text with simple built-....
