Flameshot is a free and open-source, cross-platform tool to take screenshots with many built-in features to save you time.

This is a robust, locally hosted web-based PDF manipulation tool using Docker. It enables you to carry out various operations on PDF files, including splitting, merging, converting, reorganizing, adding images, rotating, compressing, and more. This locally hosted web application has evolved to encompass a comprehensive set of features, addressing all your PDF requirements.

Stirling PDF does not initiate any outbound calls for record-keeping or tracking purposes.

All files and PDFs exist either exclusively on the client side, reside in server memory only during task execution, or temporarily reside in a file solely for the execution of the task. Any file downloaded by the user will have been deleted from the server by that point.

Scientists have created a blazing-fast scientific camera that shoots images at an encoding rate of 156.3 terahertz (THz) to individual pixels — equivalent to 156.3 trillion frames per second. Dubbed SCARF (swept-coded aperture real-time femtophotography), the research-grade camera could lead to breakthroughs in fields studying micro-events that come and go too quickly for today’s most expensive scientific sensors.

SCARF has successfully captured ultrafast events like absorption in a semiconductor and the demagnetization of a metal alloy. The research could open new frontiers in areas as diverse as shock wave mechanics or developing more effective medicine.

Shrinking the computer chip is one of humanity’s greatest scientific feats. It has enabled the processing power that has digitalised almost every aspect of our lives.

To understand how the latest chips work and where technological breakthroughs are being made, we need to travel beyond objects measured on familiar scales.

It is tempting to look for parallels with human empires. Perhaps it is impossible not to see rhymes between the natural and human worlds, and as a science journalist I’ve contributed more than my share. But just because words rhyme, it doesn’t mean their definitions align. Global ant societies are not simply echoes of human struggles for power. They are something new in the world, existing at a scale we can measure but struggle to grasp: there are roughly 200,000 times more ants on our planet than the 100 billion stars in the Milky Way.

A judge has dismissed a complaint from a parent and guardian of a girl, now 15, who was sexually assaulted when she was 12 years old after Snapchat recommended that she connect with convicted sex offenders.

According to the court filing, the abuse that the girl, C.O., experienced on Snapchat happened soon after she signed up for the app in 2019. Through its "Quick Add" feature, Snapchat "directed her" to connect with "a registered sex offender using the profile name JASONMORGAN5660." After a little more than a week on the app, C.O. was bombarded with inappropriate images and subjected to sextortion and threats before the adult user pressured her to meet up, then raped her. Cops arrested the adult user the next day, resulting in his incarceration, but his Snapchat account remained active for three years despite reports of harassment, the complaint alleged.

Google regularly launches updates to its algorithm to continuously improve search results quality. Think of these updates as a refresh of the system where rankings change: some websites see an improvement while others see a decline.

We know that at the end of the day, Google will reward us if our readers find our articles useful.

Or that’s what we thought.

You might have noticed that no matter what you google, there’s always a selection of the same publishers showing up at the top of the results.

The new certifications for HDMI cables are now slowly coming onto the market. Known as Gen 2, these certifications will provide verification for the authenticity of a given cable and gradually replace the first generation certifications.

This formally began in May 2023, but the HDMI Licensing Administrator (HDMI LA) has allowed the old labels to continue to be used until stocks of the corresponding cables have all been sold. In its February newsletter, cable manufacturer Club3D drew attention to this change and stated that it is currently changing its label fulfillment provider, so packs with both the old and the new certifications will soon appear in stores.

The new certification has the advantage that it can be checked more easily. According to the HDMI LA, a simple scan of the QR code on the pack is enough to verify its authenticity. The old verification, on the other hand, required the proprietary HDMI app.

The first reason bird legs look strangely thin is that the rest of their body is mostly covered by feathers, which can dramatically magnify its apparent size, says Julia Clarke, a paleontologist who studies bird evolution at the University of Texas at Austin. Birds’ relatively meatier thighs are tucked underneath their feathers, and most birds have scaly lower legs, Clarke says, which makes these limbs look oddly small and naked. Birds that have feathers down to their toes—such as owls and some domestic chickens—appear to have thicker shins than their bare-legged cousins.

But it’s not just a visual illusion: bird legs have some genuine differences from legs of other living animals.

Ubuntu's popularity often makes it the default choice for new Linux users. But there are tons of other Linux operating systems that deserve your attention. As such, I've highlighted some Ubuntu alternatives so you can choose based on your needs and requirements—because conformity is boring.
