The DJB Legacy (2011)





Who’s this DJB guy and why is it so special?

He is a mathematician and the author of a well-known and widely used MTA.

He was active for a while in Unix-related activities

The Unix programming community is known for its controversial figure, mostly
By being vocal against well-known authors

I don’t care about controversy. I’m interested in the code. I was

Its design principles and how it was made are important. Then,
I fell into the rabbit hole.

You don’t have to like the guy. I don’t even know him.
However, this is completely irrelevant. Only thing that matters is
matters is that DJB’s software is right in so
There are many options. This software works. DJB’s design

It’s already
a lot you can do with

DJB is, however, a pioneer in my eyes. It was possible, he proved it was possible

So, skalibs.

One of the “DJB philosophy” key points is to question the

What are you doing?

  • An alternative way of thinking is to ask yourself:
    “Is my interface adequate for the task?”

    • If yes: perfect, use that interface.
    • If no: then do not use that interface, duh. Design

      It will be much easier to maintain.

Interfaces should be questioned right down to the libc. You should ask interfaces questions right down to the libc.
Software cannot be built on weak foundations. A system is a system.
and network programmer’s point of view, one thing is clear: most
standard libc interfaces suck.
There are no buffered, asynchronous interfaces.

This is where skalibs originates. Skalibs is a result of questioning

The existing interfaces make it difficult to write secure, reliable code.

DJB isn’t a guru and I’m certainly not a brainwashed fan.
The “DJB supporters” are not a cult. We think DJB brought about these changes.
Unix, and the wider software programming world in general, have something in common.
We learned from him and now write software.
He had sound principles which he applied and that we now share.

Nothing announces official launch date for new Ear (stick) AirPods alternatives




Nothing announces official launch date for new Ear (stick) AirPods alternatives

True to form, Nothing has just announced the full reveal date for its upcoming audio product, Ear (stick). 

So, an announcement about an announcement. You’ve got to hand it to Carl Pei’s marketing department, they never miss a trick.

What we’re saying is that although we still have ‘nothing’ conclusive about the features, pricing or release date for the Ear (stick) except an image of another model holding them (and we’ve seen plenty of those traipsing down the catwalk recently), we do have a date – the day when we’ll be granted official access to this information. 

That day is October 26. Nothing assures us that on this day we’ll be able to find out everything, including pricing and product specifications, during the online Ear (stick) Reveal, at 3PM BST (which is 10AM ET, or 1AM on Wednesday if you’re in Sydney, Australia) on (opens in new tab)

Any further information? A little. Nothing calls the Ear (stick), which is now the product’s official name, “the next generation of Nothing sound technology”, and its “most advanced audio product yet”. 

But that’s not all! Apparently, Ear (stick) are “half in-ear true wireless earbuds that balance supreme comfort with exceptional sound, made not to be felt when in use. They’re feather-light with an ergonomic design that’s moulded to your ears. Delivered in a unique charging case, inspired by classic cosmetic silhouettes, and compactly formed to simply glide into pockets.” 

Opinion: I need more than a lipstick-style case

It’s no secret that I want Nothing’s earbuds to succeed in world dominated by AirPods; who doesn’t love a plucky, eccentric underdog? 

But in order to become some of the best true wireless earbuds on the market, there is room for improvement over the Nothing Ear 1, the company’s inaugural earbuds. 

Aside from this official ‘news’ from Nothing, leaked images and videos of the Ear (stick) have been springing up all over the internet (thank you, developer Kuba Wojciechowski) and they depict earbuds that look largely unchanged, which is a shame. 

For me, the focus needs to shift from gimmicks such as a cylindrical case with a red section at the end which twists up like a lipstick. Don’t get me wrong, I love a bit of theater, but only if the sound coming from the earbuds themselves is top dog. 

As the natural companions for the Nothing Phone 1, it makes sense for the Ear (stick) to take a place similar to that of Apple’s AirPods 3, where the flagship Ear (1) sit alongside the AirPods Pro 2 as a flagship offering. 

See, that lipstick case shape likely will not support wireless charging. That and the rumored lack of ANC means the Ear (stick) is probably arriving as the more affordable option in Nothing’s ouevre. 

For now, we sit tight until October 26.

YouTube could make 4K videos exclusive to Premium subscribers

You might soon have to buy YouTube Premium to watch 4K YouTube videos, a new user test suggests.

According to a Reddit thread (opens in new tab) highlighted on Twitter by leaker Alvin (opens in new tab), several non-Premium YouTube users have reported seeing 4K resolution (and higher) video options limited to YouTube Premium subscribers on their iOS devices. For these individuals, videos are currently only available to stream in up to 1440p (QHD) resolution.

The apparent experiment only seems to be affecting a handful of YouTube users for now, but it suggests owner Google is toying with the idea of implementing a site-wide paywall for access to high-quality video in the future.

So, after testing up to 12 ads on YouTube for non-Premium users, now some users reported that they also have to get a Premium account just to watch videos in 4K. 1, 2022

It’s no secret that Google has been searching for new ways to monetize its YouTube platform in recent months. In September, the company introduced five unskippable ads for some YouTube users as part of a separate test – an unexpected development that, naturally, didn’t go down well with much of the YouTube community. 

A resolution paywall seems a more palatable approach from Google. While annoying, the change isn’t likely to provoke the same level of ire from non-paying YouTube users as excessive ads, given that many smartphones still max out at QHD resolution anyway. 

Of course, if it encourages those who do care about high-resolution viewing to invest in the platform’s Premium subscription package, it may also be more lucrative for Google. After all, YouTube Premium, which offers ad-free viewing, background playback and the ability to download videos for offline use, currently costs $11.99 / £11.99 / AU$14.99 per month.

Suffice to say, the subscription service hasn’t taken off in quite the way Google would’ve hoped since its launch in 2014. Only around 50 million users are currently signed up to YouTube Premium, while something close to 2 billion people actively use YouTube on a monthly basis. 

Might the addition of 4K video into Premium’s perk package bump up that number? Only time will tell. We’ll be keeping an eye on our own YouTube account to see whether this resolution paywall becomes permanent in the coming months.
