Chrome for Android doesn't have extensions, but Edge now has a whole store
Microsoft edge's latest build version 134.0.3124.57, just added a whole new web-store for Android user unlike google. Extensions are great for adding a tiny bit of functionality to a browsing experience without dedicating an entire app to run in the background. For instance, some users like to use VPNs securely tied in from the browser itself rather than running the full-scale app.

Decrypting encrypted files from Akira ransomware using a bunch of GPUs
I recently helped a company recover their data from the Akira ransomware without paying the ransom. I’m sharing how I did it, along with the full source code. The code is here: https://github.com/yohanes/akira-bruteforce To clarify, multiple ransomware variants have been named Akira over the years, and several versions are currently circulating. The variant I encountered has been active from late 2023 to the present (the company was breached this year). There was an earlier version (before mid-2023) that contained a...

The findings, published in Nature Medicine, suggest time-restricted eating provides beneficial effects irrespective of the time of day individuals have their meals.

Block Diffusion: Interpolating Between Autoregressive and Diffusion Models
View PDF Abstract:Diffusion language models offer unique benefits over autoregressive models due to their potential for parallelized generation and controllability, yet they lag in likelihood modeling and are limited to fixed-length generation. In this work, we introduce a class of block diffusion language models that interpolate between discrete denoising diffusion and autoregressive models. Block diffusion overcomes key limitations of both approaches by supporting flexible-length generation and improving inference efficiency with KV caching and parallel token sampling. We propose a recipe...

The long flight to teach an endangered ibis species to migrate
That summer, Schiffman, who had recently made a documentary for National Geographic about relocating giraffes, read a story in the Times about Fritz, the Waldrapp project (Waldrapp is the German term for the species), and the first migration to Spain. Schiffman’s father was an I.T./A.V. technician who’d done some work for Matt Damon. Damon and Ben Affleck have a production company called Artists Equity, which agreed to fund a trip to Spain. Schiffman caught up with the migration outside Roquetes....

Statistical Formulas for Programmers (2013)
By Evan Miller May 19, 2013 Being able to apply statistics is like having a secret superpower. Where most people see averages, you see confidence intervals. When someone says “7 is greater than 5”, you declare that they’re really the same. In a cacophony of noise, you hear a cry for help. Unfortunately, not enough programmers have this superpower. That’s a shame, because the application of statistics can almost always enhance the display and interpretation of data.As my modest contribution...

Carefully but Purposefully Oxidising Ubuntu
Last month I published Engineering Ubuntu For The Next 20 Years, which outlines four key themes for how I intend to evolve Ubuntu in the coming years. In this post, I’ll focus on “Modernisation”. There are many areas we could look to modernise in Ubuntu: we could focus on the graphical shell experience, the virtualisation stack, core system utilities, default shell utilities, etc. Over the years, projects like GNU Coreutils have been instrumental in shaping the Unix-like experience that Ubuntu...

Are There Opportunities to Use OODA Loops in Your Software Project?
The world is full of good ideas misapplied, so I want to be careful when discussing OODA loops. The OODA loop was created as an idea in the study of war. War is endemic to the way humans are (at least, so far), but it is always, in part or in whole, a tragedy. And characterizing software engineering, business operations or entrepreneurship as a conflict in that vein can create an overly aggressive view of the world. But, I belive,...

Amateur Telescope Making Main Page
Russell PorterGrinding a Mirror "For it is true that astronomy, from a popular standpoint, is handicapped by the inability of the average workman to own an expensive astronomical telescope. It is also true that if an amateur starts out to build a telescope just for fun he will find, before his labors are over, that he has become seriously interested in the wonderful mechanism of our universe. And finally there is understandably the stimulus of being able to unlock the...

Cursor told me I should learn coding instead of asking it to generate it
Hi all, Yesterday I installed Cursor and currently on Pro Trial. After coding a bit I found out that it can’t go through 750-800 lines of code and when asked why is that I get this message: Not sure if LLMs know what they are for (lol), but doesn’t matter as a much as a fact that I can’t go through 800 locs. Anyone had similar issue? It’s really limiting at this point and I got here after just 1h...

FTC can't afford to fight Amazon's allegedly deceptive sign-ups after DOGE cuts
“What I heard is that they’ve got the whole trial team still intact," Hueston argued. "Maybe there’s going to be an office move. And by the way, both in government and private sector, I’ve never heard of an office move being more than a few days disruptive.” At the hearing, Chun appeared confused about how the extra time would benefit the FTC, which he said is "in crisis now, as far as resources" go, without any signs that circumstances "will...

Mercedes-Benz Drives Toward Solid-State EV Batteries
Solid-state batteries remain several years from auto showrooms. The auto industry is pursuing the batteries, which replace liquid electrolytes with a solid ceramic or glass material, because of their potential to carry decisively more energy, charge faster and improve vehicle safety by reducing flammability over other types of lithium-ion batteries.Now, Mercedes-Benz and solid-state battery manufacturer Factorial Energy have reached a hopeful halfway point, strapping semi-solid-state cells to the German automaker’s flagship electric sedan. Mercedes announced it has begun road-testing the...

My teen years: The transputer operating system
In my previous article I talked about how I managed to create a self-contained operating system for transputer. This included the basic operating system, a text editor, a Small-C compiler, and an assembler. The year was 1995, I was age 16, Lemon Tree and Zombie were being played in the radio, ARPANET closed around 1990, and it started to be known as Internet, and in Mexico only a handful of people used it through Compuserve Mexico. I wasn't so lucky...
