Recently I realized that my personal notes are being replicated far more times than I originally intended. Here’s a concise overview.
For years, I captured quick thoughts in Apple Notes, but as the collection grew into a personal knowledge base, I needed better structure. I moved to Obsidian, which is powerful, yet too heavy for fast note capturing. Looking for a lighter, cross-platform solution with an open API, I adopted Memos as my primary note-taking tool.
Although iCloud and its backup share the same provider, they reside in separate storage systems. In total, every note is stored in seven distinct locations.
This guide was created for MinIO release RELEASE.2025-05-24T17-08-30Z which is the latest version tag available at the moment of publication.
bash
mc alias set myminio https://minio.example.com YOUR_ACCESS_KEY YOUR_SECRET_KEY
mc mb myminio/public
bash
mc anonymous set download myminio/public
This does the following:
First, run the following command to get the current JSON policy created by the previous step.
bash
mc anonymous get-json myminio/public
The output will look like the following: “That’s the policy defined by the 'download' preset.
json
{
"Statement": [
{
"Action": [
"s3:GetBucketLocation",
"s3:ListBucket"
],
"Effect": "Allow",
"Principal": {
"AWS": [
"*"
]
},
"Resource": [
"arn:aws:s3::: public"
]
},
{
"Action": [
"s3:GetObject"
],
"Effect": "Allow",
"Principal": {
"AWS": [
"*"
]
},
"Resource": [
"arn:aws:s3::: public/*"
]
}
],
"Version": "2012-10-17"
}
The line that allows anyone to list the files available in bucket is s3:ListBucket in the 'Action' property. Just remove it and upload the policy again with the following command.
bash
mc anonymous set-json /path-to-your-edited-json-policy.json myminio/public
Where file /path-to-your-edited-json-policy.json contains the edited version of your policy.
json
{
"Statement": [
{
"Action": [
"s3:GetBucketLocation"
],
"Effect": "Allow",

Open the root of your MinIO S3 endpoint. For example 'youbucket.s3.yourdomain.com'. If you get an XML-formatted error saying ‘Access Denied’, then everything is working as expected!
We have great news! As of today, RevoTale runs entirely on a self-hosted infrastructure. The final step was migrating from Cloudflare R2 Object Storage to a self-hosted alternative — and we’re happy to announce that our media storage is now powered by an S3-compatible MinIO server.
It wasn’t easy. Due to the limitations of Cloudflare’s free plan, we had to move away from their entire infrastructure and even switch to a different domain registrar. The final straw was Cloudflare charging $10 for custom SSL just to support fourth-level domains. Of course, in addition to this, there were other unpleasant things we encountered related to Cloudflare's monopolistic tendencies.
So yes—starting today, every inch of our infrastructure is built entirely with open-source tools, and our stability is our responsibility.
Losing a single night of sleep can indeed impair cognitive functions, but the duration and extent of impairment can vary. Research suggests that after just one night of sleep deprivation, cognitive functions like attention, reasoning, and decision-making are affected, and this impact can last beyond the immediate day after. Some studies show that full recovery of cognitive function may take up to 3-4 days, depending on how much sleep debt was accrued and how well the recovery sleep is.
However, the effects are not equally severe for everyone, and some cognitive abilities might bounce back faster than others. While it's important to catch up on sleep, recovery can differ depending on individual resilience and the sleep quality afterward.
We are excited to tell you that starting today we use self-hosted imgproxy to create image thumbnails instead of Cloudflare Transform Images.
imgproxy allows us to extensively customise the behaviour of image resizing.imgproxy, especially since we manage it through our own proxy server.imgproxy allows us to test production-grade infrastructure locally.imgproxy is written in Go programming language. Since this is the main backend language we use, it's easier to fix bugs we discover related to image resizing.There are a few potential reasons why some people may feel sleepy after consuming caffeine:
It's important to note that while these factors can contribute to sleepiness after caffeine consumption, the effects of caffeine can vary significantly from person to person.
Friedrich Engles once said.
Life is the mode of existence of protein bodies, the essential element of which consists in continual metabolic interchange with the natural environment outside them, and which ceases with the cessation of this metabolism, bringing about the decomposition of the protein.

We're excited to share that revotale.com scored 96 on mobile PageSpeed Insights! Even better — the blog notes page hits a perfect 100 🎯
It took some fine-tuning, but it was absolutely worth it.
Here’s what’s powering our performance:
We see this as a foundation — keeping our website performance scores high will remain a core principle as we grow. It won’t always be easy, but we believe this discipline will bring long-term benefits across the board.
If the site generates tons of low-value, unique search URLs (e.g., from bots or typo queries), consider:
xml
<meta name="robots" content="noindex, follow">
But if you expect users to search the same queries again or want to rank for long-tail queries, keep it indexable.
I’m excited! Thanks to GitHub Copilot, I can now automate the process of finding missing translations across the project. Instead of using complex utilities or manually reviewing everything, now I just need a simple prompt.
So, the problem was that GitHub markdown files do not respect image width in case content is shorter than image. Thanks to HTML. There is " " filler in HTML specification that does role of "Non-breaking invisible glue" so it can simulate table width in case there is not enough symbols in table cell content.
The neocortex, which evolved relatively recently, is located on the surface of the brain. Proportionally, this level occupies more space in the brains of primates than in those of other animal species. Cognition, memory storage, sensory processing, abstraction, philosophy, self-reflection — all reside here.
Read a terrifying passage in a book, and level 3 will signal level 2 to make you feel fear, which in turn will instruct level 1 to initiate trembling. Watch an Oreo commercial, and you’ll feel the urge to eat it — that’s level 3 influencing levels 2 and 1.
Think about the fact that your loved ones (or children in a refugee camp) won’t live forever, or that the tree of the Na’vi in Avatar was destroyed by those awful humans (even though — wait, the Na’vi aren’t real!), and level 3 will engage levels 2 and 1, making you feel sorrow, with a stress response as if you were running from a lion.
This region evolved later and developed in mammals. MacLean explained that this level is associated with emotions — a kind of mammalian invention. If you witness something brutal and horrifying, the neural structures at this level send a signal to the ancient level 1, making you tremble with emotion. If you’re heartbroken over unrequited love, areas here nudge level 1 to trigger cravings for unhealthy food. If you’re a rodent and hear a cat, neurons in this region push level 1 to initiate a stress response.
The ancient component of the brain — its foundation — is present across a range of species, from humans to geckos. This level controls automatic regulatory functions. If body temperature drops, this part of the brain responds by instructing the muscles to shiver. If blood glucose levels fall, it’s detected here too, triggering the sensation of hunger. If a person experiences an injury, another neural center at this level initiates a stress response.
Attention! These are NOT literal layers of the brain.
Let’s begin by examining the macro-organization of the brain. For this, we’ll use a model proposed in the 1960s by neuroscientist Paul MacLean. His “triune brain” model describes the brain as having three functional domains:
So, our brain is divided into three functional blocks, with the usual advantages and disadvantages that come with categorizing any continuum. The biggest drawback is its excessive simplification.
Level 1: The ancient component of the brain — its foundation — present across various species.
Level 2: A region that evolved later and developed in mammals.
Level 3: The neocortex, which evolved relatively recently and is located on the surface of the brain.
Anatomically, there is significant overlap between these three levels (for instance, one part of the cortex could be considered part of level 2 — more on this later).
The flow of information and commands doesn’t just move top-down, from level 3 to 2 and 1. One strange and interesting example we’ll explore in Chapter 15: if a person is holding a cold drink (temperature processed by level 1), they are more likely to perceive a new acquaintance who approaches them as a “cold” person (level 3).
The automatic aspects of behavior (in simplified terms — the domain of level 1), emotions (level 2), and thinking (level 3) are inseparable.
The triune model gives the misleading impression that evolution simply stacked one level on top of another, without any changes to the ones that already existed.
Despite all its flaws — which MacLean himself acknowledged — this model will serve as a useful organizational metaphor for us.
When cognitive load on the prefrontal cortex is increased, subjects eventually become less inclined to engage in prosocial behavior, such as charity or helping others, and more inclined to lie. When the load is increased specifically through tasks requiring constant emotional regulation, participants are later more likely to cheat on their own diets. (Source: Inzlicht and Marcora, “The Central Governor Model of Exercise Regulation Teaches Us Precious Little About the Nature of Mental Fatigue and Self-Control Failure,” Frontiers in Psychology 7 (2016).)
Damage to certain areas of the cortex due to a stroke can block the ability to speak; yet some patients manage to convey their cerebral world of language through alternative emotional, limbic pathways — they can sing what they want to say. The cortex and the limbic system are inseparable because numerous neural fibers connect them. Importantly, these fibers ensure a bidirectional communication: the limbic system “talks” to the cortex, not just obeys it. The false dichotomy between thought and feeling is exposed in the classic work Descartes’ Error by neurologist Antonio Damasio of the University of Southern California.
Willpower isn’t just a metaphor — it’s the work of the brain’s frontal cortex, which consumes a tremendous amount of energy to function. Its activity is marked by an extremely high level of metabolism and the activation of genes involved in energy production. Self-control is a finite resource. That’s why tasks requiring this part of the brain become much less effective after something like a shopping spree.
The ventromedial prefrontal cortex (vmPFC) is a part of the prefrontal cortex in the mammalian brain. The ventral medial prefrontal is located in the frontal lobe at the bottom of the cerebral hemispheres and is implicated in the processing of risk and fear, as it is critical in the regulation of amygdala activity in humans. It also plays a role in the inhibition of emotional responses, and in the process of decision-making and self-control. It is also involved in the cognitive evaluation of morality.
The dorsomedial prefrontal cortex (dmPFC or DMPFC is a section of the prefrontal cortex in some species' brain anatomy. It includes portions of Brodmann areas BA8, BA9, BA10, BA24 and BA32, although some authors identify it specifically with BA8 and BA9. Some notable sub-components include the dorsal anterior cingulate cortex (BA24 and BA32), the prelimbic cortex, and the infralimbic cortex.
The following information was taken from the book Behave, from the chapter about oxytocin.
There was a study that makes people squirm due to how much it reflects stereotypical human couples. In tamarin monkeys, who also form pair bonds, active grooming and frequent physical contact were indicators of high oxytocin levels in the female partners. And what predicted high oxytocin levels in the males? Lots of sex.
According to Robert Sapolsky in Behave: The Biology of Humans at Our Best and Worst:
It is a mistake to think that understanding everything must lead to forgiveness.
The fact that we can explain a horrific act of murder through neurobiology should not necessarily mitigate the sentence. A young man commits a terrible act under the influence of impulses, and neuroimaging reveals a deficiency in his prefrontal cortex (PFC) neurons. This leads to a dualistic temptation to consider his behavior more ‘biological’ or ‘organic’ in some vague sense than if he had committed the same act with a normal PFC.
However, the horrific impulsive act of this young man is unequivocally ‘biological’—with or without a PFC.
I used a lot TailwindCSS 3 + SCSS + CSS modules. Migrating it to Tailwind v4 was so painful.....
