Why Android’s Built-In Gallery Apps Just Don’t Cut It

Let’s face it: the gallery app on your Android phone is fine for flipping through photos, but it’s a mess when you hit play on a video. You’ll get playback, sure, but try skipping forward by 10 seconds or adjusting the volume without covering the screen. Most gallery apps lack even basic video controls, which is why millions of people install a dedicated player like VLC media player or MX Player.

Those two have been the go-to names for years. But they’ve also been frustratingly slow to evolve. Gesture controls? Clunky. Subtitle syncing? A chore. Streaming from a network drive? Good luck. That’s why I was genuinely surprised when I stumbled upon mpvRex, an open-source Android video player that feels like it was built by someone who actually watches videos on a phone.

What Is mpvRex? A Quick Intro

mpvRex is a fork of the popular mpv media player, but it’s been rebuilt from the ground up for Android. The project is available on GitHub and F-Droid, and it’s completely free with no ads or tracking. If you’ve ever used mpv on a desktop, you know how powerful and configurable it is. mpvRex brings that same DNA to your pocket.

But here’s the thing: it’s not just a port. The developer added a whole layer of Android-specific polish that VLC and MX Player have somehow never managed to ship. Let me walk you through the standouts.

Gesture Controls That Actually Make Sense

VLC on Android has had gesture support for years, but it’s basic. Swipe left or right to seek, up or down for volume and brightness. That’s about it. MX Player is similar. mpvRex, on the other hand, takes a page from the best iOS players like Infuse and nPlayer.

You get customizable zones on the screen. Want to use the left half for brightness and the right half for volume? Done. Prefer a double-tap to pause and a two-finger swipe to seek? You can set that up in seconds. The gesture engine is also more accurate — it doesn’t accidentally trigger when you’re just trying to hold the phone. It’s the kind of control that makes you wonder why the big players haven’t copied it yet.

Seek Precision That Doesn’t Drive You Crazy

One of my biggest pet peeves with VLC is the seek bar. It’s jumpy, and thumbnails are almost useless. mpvRex gives you a smooth, preview-rich seek bar with frame-accurate scrubbing. You can actually see where you’re skipping to, which is invaluable for finding a specific scene in a long video.

Subtitle Support That Puts Others to Shame

Subtitles are a mess on most Android players. You either get a tiny font that’s hard to read or a giant one that covers the whole screen. mpvRex lets you adjust font size, color, outline, shadow, and position — all on the fly with a simple overlay. You can even set a delay for subtitles that are out of sync, and it remembers your adjustment per file.

But the real killer feature? Online subtitle download. The app integrates with OpenSubtitles, so you can search and fetch subtitles directly from within the player. No more downloading a .srt on your browser and fumbling with file managers. VLC has promised this for years but still doesn’t offer it on Android. MX Player had it, but they’ve been pushing ads and bloatware so hard that the feature feels buried.

Streaming and Network Playback Done Right

Most players treat network streaming as an afterthought. You might get SMB support, but it’s flaky and slow. mpvRex handles SMB, FTP, and HTTP shares with surprising reliability. It also supports streaming from YouTube and other sites via yt-dlp integration — a feature that’s technically against Google’s ToS, but if you’re into that sort of thing, it’s there.

For local files, the player supports virtually every codec you can throw at it, including HEVC, AV1, and even 10-bit HDR content. It’ll play MKV, MP4, AVI, FLV, and a dozen other containers without breaking a sweat. And it does all this while being surprisingly light on battery — much better than VLC, which can turn your phone into a hand warmer.

Customization and Open-Source Community

Because mpvRex is open source, you can tweak almost everything. The configuration files are accessible, and the community has already built a library of custom scripts and shaders. If you’re the type who likes to fine-tune your video output, you’ll feel right at home.

But even if you never touch a config file, the default experience is polished. The dark theme is sleek, the interface is minimal, and there are no ads. None. Compare that to MX Player, which now shows full-screen ads unless you pay, or VLC, which has been adding more “recommended” content to its home screen.

How to Get mpvRex

You can grab mpvRex from the F-Droid store or directly from the GitHub releases page. It’s also available on the Play Store, but the F-Droid version is often more up-to-date. Just be aware that the app is still in active development, so you might run into the occasional bug. That said, the core playback engine is rock solid.

If you’re tired of the same old players that haven’t changed in a decade, give mpvRex a shot. It might just become your new default. And if you’re curious about other open-source Android apps, check out our guide to the best open-source Android apps for 2024.

From Gems to Employees: How to Turn AI Tools Into Autonomous Workers

Published

The Weekend Is Almost Here: Don’t Miss This AI Roundup

Friday’s looming. You’ve got one foot out the door, but before you log off, there’s a batch of AI intel worth your attention. Save it for later if you must — just don’t skip it.

This week’s edition zeroes in on three areas that matter if you’re building a serious AI workflow: converting Google Gems and custom GPTs into reusable Skills, training autonomous AI employees that actually meet your standards, and the latest industry moves from Gemini and others.

What Are Gems and GPTs — and Why Convert Them?

You’ve probably tinkered with custom GPTs in ChatGPT or played with Gems in Gemini. They’re handy, sure. But they’re also siloed. A GPT lives inside ChatGPT; a Gem stays in Gemini. That’s fine for personal use, but it falls apart when you want a consistent process across your whole operation.

The fix? Turn them into Skills. A Skill is a packaged, reusable capability that any AI agent can call on — regardless of the underlying model. Think of it as the difference between hiring a freelancer who only works in one app and hiring someone who can plug into your entire tech stack.

This isn’t just a nice-to-have. If you’re serious about building autonomous AI employees, Skills are the building blocks. They let you standardize how your AI handles specific tasks, so you’re not reinventing the prompt wheel every Monday morning.

How the Conversion Works

  • Audit what you have: List every custom GPT and Gem you’ve created. Which ones actually save time?
  • Extract the core logic: Strip away the interface and isolate the instructions, knowledge files, and workflow steps.
  • Repackage as a Skill: Define clear inputs and outputs. A Skill should be callable by any agent, not tied to a chat window.

It sounds technical, but the payoff is real. Once your best prompts become Skills, they’re versionable, shareable, and — crucially — usable inside automated pipelines.

Training AI Employees That Match Your Standards

Here’s the uncomfortable truth: most people’s AI assistants are mediocre because they’re trained by accident, not by design. You let the model guess what “good” looks like. Then you’re surprised when the output is generic.

Training an autonomous AI employee is different. You’re not just writing a prompt — you’re onboarding someone. That means setting expectations, providing examples of excellent work, and establishing guardrails for when things go sideways.

Start with a single role. Pick one repetitive task — say, drafting client emails or summarizing industry reports. Build a Skill for it, then train the agent on your feedback loop. Show it what a 9-out-of-10 response looks like. Correct it when it drifts. Over time, it gets faster and sharper.

And here’s the key: it works while you sleep. That’s the whole point of autonomous. You set the standard, the AI meets it, and you’re not in the loop for every single output.

A Simple Training Framework

  1. Define the role: Write a one-paragraph job description for your AI employee.
  2. Give it a Skills stack: Assign the Skills it needs to do the job.
  3. Run a pilot: Test on low-stakes tasks first. Measure accuracy, not speed.
  4. Iterate: Feed corrections back into the Skill definitions.

Done right, you’ll have a workforce that scales without headcount. That’s not sci-fi — it’s just good process design.

Industry News: Gemini and the Wider AI Landscape

Meanwhile, the big players aren’t standing still. Gemini has been rolling out updates that blur the line between chatbot and coworker. New capabilities are pushing toward longer context windows, better tool use, and more reliable multi-step reasoning.

What does that mean for you? The gap between consumer AI and enterprise AI is shrinking. Tools that felt experimental six months ago are now production-ready. But that also means the bar for differentiation is higher. Anyone can chat with a bot. Few can deploy a fleet of autonomous AI employees that actually deliver.

The winners this year won’t be the ones with the fanciest models. They’ll be the ones who figured out how to turn AI into a repeatable, trainable workforce. That starts with Skills — and ends with results.

So before you head out for the weekend, ask yourself: are you still playing with AI, or are you actually putting it to work?

Judge Hands X a Split Verdict in Trademark Fight With Twitter Rival Tweet.app

Published

Tweet.app trademark ruling

A Startup Built on Trademark Scraps

Most social media startups begin with a big idea. Operation Bluebird began with a legal loophole. The Virginia-based company, founded by two lawyers, launched with the explicit goal of picking up the trademarks Elon Musk discarded when he renamed Twitter to X. Its homepage doesn’t hide this. It says the company wants to go back and grab what Musk dropped when he “threw the bird away on his way out.”

That’s not your typical mission statement. But it might be a clever one.

On Wednesday, a federal court in Delaware delivered a split ruling in the trademark fight between X Corp. and Operation Bluebird. Judge Colm F. Connolly granted X’s request for a preliminary injunction on eight Twitter-related marks. That means the startup can’t call itself Twitter.now. The core “Twitter” name stays with X, at least for now.

But here’s the twist. The judge denied X’s motion regarding two other marks: the word “tweet” and the Twitter bird logo. He wrote that Operation Bluebird was “likely to succeed in proving both that X Corp. discontinued the bona fide use of the Tweet mark and Bird logo and that it intends not to resume the use of the marks.”

In plain English: X gave up on those words and images. The public kept using them, and now a rival can too.

The Lawyers Behind the ‘Tweet’ Revival

Operation Bluebird isn’t run by Silicon Valley dreamers. It’s led by Michael Peroff, an Illinois-based attorney, and Stephen Coates, who once worked as a trademark lawyer at Twitter. Their legal pedigree makes their claim of wanting to build a fresh social network feel a bit thin. The real prize here is likely the trademarks themselves, which carry value independent of any actual product.

Still, the startup is going through the motions. It has rebranded its website as Tweet.app and opened its doors to early testers. The company told TechCrunch that more than 172,000 people requested a handle before launch. That number probably reflects lingering public affection for the Twitter brand — a name the startup can no longer use.

There’s a catch, though. To reserve a handle and join, users must pay $20. That fee likely helps cover the mounting legal bills.

What the Judge Actually Decided

This ruling isn’t final. It’s a preliminary injunction, which means the court is weighing the likelihood of success on the merits. Judge Connolly sided with X on the eight marks tied directly to the Twitter name. He sided with Operation Bluebird on the Tweet mark and the bird logo.

The case will now proceed to a full trial to determine whether X retains any rights to the Twitter marks, given that the company now operates under the X banner in most places.

For now, the practical outcome is this:

  • X keeps exclusive rights to the “Twitter” name.
  • Operation Bluebird can use the word “tweet” and the bird logo.
  • The startup must rebrand away from Twitter.now.

A Question of Abandonment

The core legal question is whether X abandoned these marks through non-use. In trademark law, abandoning a mark means discontinuing its use with no intent to resume. Musk’s aggressive rebrand to X in 2023 left the word “tweet” and the bird logo in limbo. The company kept the Twitter handle on its own platform but stopped using the bird in most official capacities.

Coates, now president of Operation Bluebird, framed the ruling as a victory for the public. “They kept the word. They let go of the bird, and they let go of the tweet,” he wrote in an announcement shared via email with TechCrunch. “A tweet was never a corporation. It’s one person saying something. That word survived three years of a company trying to replace it, because the public declined to stop using it. We think that tells you who it belongs to.”

That’s a poetic argument. Whether it holds up in court remains to be seen.

What This Means for X and Its Rivals

For X, this ruling is a mixed bag. It protects the core Twitter trademark, which the company still uses in some contexts. But it opens the door for competitors to use the word “tweet” and the bird imagery — elements that remain culturally significant even if X has moved on.

For anyone tracking Elon Musk’s X rebrand and its legal fallout, this case is worth watching. It could set a precedent for how courts treat abandoned trademarks in the fast-moving world of social media. If X loses the full case, it might have to accept that the bird and the tweet belong to the public now.

The startup’s approach is unusual, but it’s not without precedent. Companies have long scooped up abandoned trademarks and repurposed them. The difference here is scale: Twitter’s marks are among the most recognized in internet history.

For now, Tweet.app lives. Twitter.now is dead. And the bird, it seems, has found a new perch.

I finally found an easy way to make Windows remember exactly where every app window belongs

Published

on

Windows remember app positions

Every morning, the ritual repeats. Open the same half-dozen apps, then spend five minutes dragging, resizing, and nudging each window into its designated spot across two monitors. By lunch, something shifts—a notification steals focus, a window snaps to the wrong screen—and the carefully built layout crumbles. It’s maddening.

I’d tried every trick I knew. Windows built-in snap layouts help, but they only work one window at a time. Third-party tools exist, but most feel like overkill or cost money. Then I stumbled on a free utility hiding inside PowerToys: Workspaces. It’s the closest thing to a magic button I’ve found for Windows remember app positions—and it’s genuinely easy.

What is PowerToys Workspaces?

Workspaces is a relatively new addition to Microsoft’s PowerToys suite, which has been around for years as a grab-bag of productivity utilities. It lets you capture a snapshot of your current desktop layout—which apps are open, where they sit, their size, and even which monitor they’re on—and save it as a named workspace.

Later, with one click, you can relaunch all those apps and have them snap back into their exact positions. No dragging. No resizing. No remembering which browser profile goes on the left screen. It’s like a bookmark for your entire desktop.

Why I stopped using manual snap layouts

Windows Snap Layouts (the hover-over-the-maximize-button feature) is fine for a quick two-window split. But it fails when you need a precise arrangement across multiple monitors or want to restore a full set of apps after a reboot. Workspaces solves that because it handles the whole layout as one unit, not window by window.

How to set up Workspaces in PowerToys

Here’s the part that sold me: setup takes less than a minute. You don’t need to configure anything complicated—just capture what’s already on your screen.

  1. Install PowerToys from the Microsoft Store or GitHub if you haven’t already.
  2. Open PowerToys and select Workspaces from the left sidebar.
  3. Arrange your apps the way you want them on your monitor(s).
  4. Click Capture Workspace—PowerToys takes a snapshot of every open window’s position and size.
  5. Give your workspace a name, like “Work” or “Coding Setup.”
  6. That’s it. You can now launch that workspace anytime from the Workspaces editor or a shortcut.

One note: Workspaces works best with apps that support command-line launching or have standard window handles. Most everyday programs—browsers, editors, terminals, chat apps—work flawlessly. Occasionally, a stubborn app might not restore perfectly, but in my testing, that’s rare.

Restoring a layout with one click

Once you’ve saved a few workspaces, using them is even simpler. Open the Workspaces editor, hover over a saved layout, and hit the launch button. PowerToys opens all the apps and arranges them exactly as captured. You can also assign a keyboard shortcut to each workspace, which turns the whole process into a single keystroke.

I now have three saved workspaces: one for writing (browser, editor, notes app), one for development (terminal, IDE, preview window), and one for communication (email, Slack, calendar). Morning startup went from a five-minute chore to a ten-second flick of a key.

What makes this different from other layout tools

I’ve tested utilities like FancyZones (also part of PowerToys) and paid tools like DisplayFusion. FancyZones is excellent for creating custom snap regions, but it doesn’t launch apps or restore a full set. DisplayFusion does window management across monitors, but it costs money and has a steeper learning curve.

Workspaces hits a sweet spot. It’s free, it’s built into a tool you might already use, and it requires zero configuration for basic use. If you’re juggling multiple monitors or just tired of rearranging after every reboot, this is the easy way to make Windows remember app positions without buying anything or wrestling with scripts.

Tips for getting the most out of Workspaces

  • Capture after a clean setup: Close apps you don’t want in the layout before capturing, so you don’t freeze in a stray window.
  • Use separate workspaces for different tasks: Don’t try to cram everything into one layout. Save distinct setups for distinct modes of work.
  • Combine with FancyZones: If you want more granular control over snap regions, set up FancyZones first, then capture a workspace that uses those zones.
  • Test with your key apps: Some apps (like elevated admin tools) may not restore automatically. Test your core set to see if anything needs a manual nudge.

If you’re like me and you’ve spent months fighting your own desktop, give Workspaces a shot. It’s the rare productivity fix that actually sticks.
