What is Hackers' Pub?

Hackers' Pub is a place for software engineers to share their knowledge and experience with each other. It's also an ActivityPub-enabled social network, so you can follow your favorite hackers in the fediverse and get their latest posts in your feed.

At the end of January we traveled to Lake Baikal with @bugaevc∀ {α}, ∃ bugaevc := by rfl -- our first time there, and generally in such cold weather. Imagine plane landing at ~4 AM your time and the flight attendant announcing "Welcome to Irkutsk, the temperature outside is -40°" 😆

We were well prepared though and had a great time! Lots of gorgeous scenery and a huge variety of ice types and formations. 1/2

Mist rising off Baikal surrounded by snowy hills.Fluffy icicles hanging inside a cave.Selfie of me and Sergey.Jagged, broken shards of ice on the lake.

Yes, you may be killed by falling human made space junk, but the odds remain small(ish) that will occur. The (almost inevitable) may also prevent future flights if all those in Low Earth Orbit start colliding, creating countless debris.

However, we *ALL* have to worry about the ‘chemical problem’ being created by SpaceX et al in the upper atmosphere. I have been banging on about this for a while and the attached article summarises the science in an easy to understand way - I have pasted the bit about the ‘chemical problem’ below because we *ALL* need to understand what the billionaires are doing to the planet while we are watching.

Debris on the ground attracts immediate attention, but atmospheric scientists are tracking a slower process with potentially larger consequences. When satellites vaporize in the mesosphere, 50 to 80 kilometers above Earth, they release clouds of vaporized metals that condense into aerosol particles. Those particles descend into the stratosphere, where Earth’s protective ozone layer resides.

Aluminum is the element of greatest concern. Upon reentry, aluminum oxidizes into aluminum oxide nanoparticles. A single 250 kilogram satellite generates roughly 30 kilograms of these particles. Unlike chlorofluorocarbons, which directly destroy ozone, aluminum oxide acts as a catalyst. One particle can facilitate chemical reactions that destroy thousands of ozone molecules over decades without being consumed.

Researchers from the University of Southern California’s Department of Astronautical Engineering documented an eightfold increase in atmospheric aluminum oxides between 2016 and 2022, directly correlating with the proliferation of satellite constellations, a finding reported in detail by CNET. In 2022 alone, reentering satellites released an estimated 41.7 metric tons of aluminum, approximately 30 percent more than the natural input from micrometeoroids.

Projections based on current deployment schedules suggest annual aluminum oxide emissions could reach 360 metric tons, a 646 percent increase over natural background levels, according to research highlighted by Popular Mechanics. Because these particles take 20 to 30 years to descend into the ozone layer, the atmospheric chemistry of today’s satellite fleet will not manifest as measurable ozone loss until the 2040s. By then, the upper atmosphere could already be saturated with catalysts.

NASA high altitude sampling flights over Alaska in 2023 detected the signature of this process. At approximately 60,000 feet, instruments found that 10 percent of stratospheric sulfuric acid particles larger than 120 nanometers contained aluminum and other metals traceable to spacecraft reentries, according to data presented at the American Astronomical Society meeting that year. The atmosphere now bears a permanent chemical marker of human activity in space.

The innards of an old Kingston 4GB USB stick that doesn't work properly any more. (It's detected at first, but then keeps getting reset and spewing errors a few seconds later.)

I don't know what I was expecting, but there's not much to see other than the flash controller, flash chip, and the USB connector.

Close-up photo of the top side of the green PCB extracted from a dead 4GB USB stick. The USB-A male connector is at the top, and the flash chip labelled "9904286 460.A00LF" and "4210965 6157391" is at the bottom, roughly equal in size, with 24 pins each on the top and bottom edges. There's a rectangular silver component in the middle whose label is unreadable. Other than that, there are some labels like R4/C3 printed on the PCB.Close-up photo of the underside of the same PCB, this time with the SK6211 flash controller chip visible in the centre, with 12 pins on each of its four sides. The reverse side of the PCB underneath the flash chip is the largest area visible, with printed labels like U3, R7, BC4, etc.

The Israeli military has published official data for the first time detailing how many of its soldiers hold foreign citizenship alongside Israeli nationality, revealing a large presence of dual-national personnel within its ranks.

Figures obtained by Declassified through a Freedom of Information request filed by the NGO Hatzlacha show that 50,632 serving soldiers hold at least one additional citizenship.

병리적 자기애는 ‘타인의 시선을 통해 내가 존재한다’라면, 건강한 자기애는 ‘나는 나로서, 타인은 타인으로서 구별되어 존재한다’고 할 수 있다. 내가 나에게 필요한 말을 스스로 해줄 수 있다면, 그것만으로도 나는 나에게 꽤 든든한 내 편이 될 수 있다. 쉽지 않더라도, 내가 경험했던 좋은 ‘자기대상’을 내 안으로 옮겨오는 일은 의미있는 시도가 될 것이다.

I think I just had THE fediverse moment:
Scrolling through my timeline watching text posts, photos, a peertube video...A short video.

"ah nice MTB video" , I thought. Until I saw the handle: someone@loops. Wait.. I see a loops here. This isn't just a video. This is a video on A DIFFERENT Service. And I can seamlessly interact with it.

A new service just integrated seamlessly into my timeline. No "connect your account", no "extra app", no "extra login", no, it's just there

@SnoopJ @randomgeek the problem is that the former parts do not actually give you a realistic or useful picture unless you radically commit to the latter parts and this conundrum literally explains a surprisingly high percentage of IT project failures across the entire industrial world in the last half century

開始寫電子報之後,也訂閱了好些中文電子報
看到大家主題很集中、內容很濃縮,就覺得自己寫的有點太雜

但另一方面又覺得現在寫的也算是自己想寫的,在維持風格和改善架構之間有點找不到合適的方向 :blackcat_11112: 是不是只能用時間去找風格了
