 ## Shelter
 
-I found a nice place to stay which had a stream passing by, the stream was running and from what I knew about the area, the water was safe to drink, so water was no longer an issue. I started building my shelter, got the base wooden structure down first, but there was a catch: I couldn't find any dry debris to put on top or inside. Last time I had built the same shelter it was autumn's end/early spring, so there were lots of dry, fallen leaves on the ground; But this time it's in the summer and there very few, scattered dry leaves on the ground, uncollectable.

-I decided I'm going with leaves of a small tree I had found nearby which seemed to be abundant around the area and the branches had lots of close leaves on them, looked like a good choice, but it was green. I didn't find out what I was doing wrong until I tried to sleep at night. The green leaves attracted lots of flies and insects and all sorts of annoying disturbances, and the smell wasn't helping either. I had to endure the insects throughout the night, because sleeping outside the shelter was a no-go, the dirt beneath was too cold. I hadn't put as much leaves on the ground, and the leaves were green (which also means they take more heat away), but still, it was much better than sleeping directly on the ground.

-What I learned was, **do not use green leaves for covering your shelter**. This rule applies to small shelters in which you are close to the covering, as well as the leaves you use as bedding. I've seen people using green leaves for covering big shelters which have a high ceiling, though I don't have any experience with those myself.

 ## Friction Fire
 
-The most important part of primitive living is fire, without fire you can't cook, you can't stay warm and you can't defy nocturnal predators. You also can't repel insects. You can't make a torch, so there goes an infinite list of fire applications that you will miss.

+repel insects. You can't make a torch, so there goes an infinite list of fire
+applications that you will miss.
 
-I knew the theory of friction fire in and out, how and why it works, but what I had missed was, **you are going to be in _real trouble_ if you can't find softwood**. To my surprise, searching portions of the forest, I couldn't find any softwood tree. Oaks were everywhere, as well as quite some other species of trees, but all of them were hardwood.

-I tried different combinations of the softer woods I could find, but none of them resulted in an ember, I got smoke with one combination, but that was it. After about 5-6 hours of trying, I got real tired and gave up. By the way, I tried hand-drills, I couldn't succeed with bow-drills as I couldn't find suitable cordage, I tried with a promising bark that was pretty strong, but it would break as soon as I put some pressure on it, It's also possible that I might've gone wrong in making the bow itself, so it would cause the breakage.

-So the lesson was **make sure the material you are going to practice with is available in your practice area**, had I known there were no softwood in that particular forest, I would change my destination and probably succeed somewhere else. Sure, a professional survivalist must be able to start a fire in almost all situations, but this is practice and you have to start with easier steps.

 ## Food
 
-The difficulties didn't end there, without a fire, my only hope for food was specific edible plants which can be eaten raw, or fruits. Unlucky as I was, I couldn't find a single fruit-bearing tree in the forest (I found quite a few fruit-bearing trees along the roads and paths to the forest, but not inside the forest itself), and I also couldn't find any of the other edible plants (I was mostly looking for the onion family) that I knew of.

-One of the greatest complications when starting primitive living practice anywhere other than the U.S. is that **almost all guides and materials on the topic are from, and for Northern America**. [The Falcon Guide to Edible Wild Plants](https://www.amazon.com/Edible-Wild-Plants-Falcon-Field/dp/0762774215) that I read is all about northern american plants. I knew it, but it's also the case that the Northern Hemisphere of the Earth have more common of an ecology, so most of the plants found in Northern America can also be found in places like Iran, but they have their differences. Most of the tips and tricks provided in different resources are for Northern American forests, which do not always work in other places.

 ## Psychology
 
-Apart from all the physical failures that I faced, which in turn caused frustration, I also had strong feelings of loneliness, boredom, and fear upon me. It was after failing to start a fire that I really felt the psychological burden on me. I had read about similar experiences, but believe me, the experience is hardly transmittable by words. A local rancher passing by the forest telling me about the leopard in the forest didn't make things any easier.

-Fear because I felt weak compared to the power of nature, my fear was doubled by the fact that I was alone. I felt like being in a place where everything seems to know what it is doing, but I don't; I felt lost, not knowing what to do after my basic plans had failed.

-Now I don't know if there is much you can do about the psychological part of it, I think experience is the remedy, at least I felt how different it was between the nights, the first night, even though I wasn't even _inside_ the forest much, I was almost at the border of it, it was much more creepy because it was my first time, but the second night, I was in the forest and now I had a _leopard_ in my mind pouncing on me, but I felt less fear and was more comfortable.

-But in the end, what helped me was that *I knew I was going to face a huge mental challenge along the way*, so I was more prepared. I think it's utterly important to be prepared for such psychological situations, knowing the reason behind your psychological challenges can help you overcome it to some extend.

 # Second Night
 
-The second and last night was not all that much interesting, but it was damn sure cold and hard. At first I had to deal with the insects biting me everywhere and my feet scratching while trying to sleep in the shelter that I had wrongly built. After getting over that one and sleeping for what seemed to be ~2 hours, I woke up and felt the air temperature decreasing. I still got to sleep in intervals of 30 minutes until I woke up at around ~4 AM and my whole body was shaking. I couldn't do much, all I did was gather the leaves underneath a little closer and more dense, and crunch my body into a ball so I felt just a little warmer, but still shaking. It took ages for the last two and a half hours to pass until dawn. At dawn I got up quickly and walked around a little to warm myself up, and then waited until I could barely see my surroundings, then I started walking out of the forest.

 # Bottom Line
 
-It was a hard trip, I lost about 2kg (4lb) weight, but all in all the experience was a good one, I certainly learned a lot and I'm not going to make the same mistakes again. I should definitly practice more and keep working on my skills.

 # Drugs, Medicine, and Medical Devices
 
-There are various sources and articles on how the U.S. sanctions have affected Iranian patients by limiting exports of drugs, medical devices or by indirectly disrupting the pharmaceutical industry by cutting exports of raw material used by these companies to produce medical drugs. Almost every person living in Iran can consciously feel the shortage of drugs and their growing price, but I will refer to an article on NCBI as a proof.

 Quoting from [NCBI: Addressing the impact of economic sanctions on Iranian drug shortages in the joint comprehensive plan of action: promoting access to medicines and health diplomacy](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4897941/):
 
 <blockquote>
-Although the revised and current Iranian sanctions regime does not specifically prohibit the export of humanitarian goods and pharmaceuticals, many of the administrative and regulatory processes have made it difficult to export life-saving medicines to Iran. This includes the need to navigate a complex export control regulatory process, the inability of Iranian banks to do business with the international banking system and U.S. corporations, currency shortages, and the inability to secure terms of shipping, insurance and other services needed to facilitate medicines trade [4]. As a result, millions of Iranians that suffer from life-threatening diseases have experienced “exorbitant prices”, stock outs of medicines, and are often forced to purchase drugs from the black market.

 And on the topic of weakening of the pharmaceutical companies:
 
 <blockquote>
-Inaccessibility of vital medications and their raw ingredients combined with Iran’s weakening domestic pharmaceutical industry has also resulted in an influx of counterfeit, fraudulent, and substandard medicines into Iran’s health care system. An unregulated black market has developed as a byproduct of drug shortages, introducing medications whose origins and authenticity are often unknown, and has led to expired medications’ distribution and sale, even at potentially very high prices [8]. Hence, the global counterfeit medicines trade, recognized as a serious public health concern, is one that is currently being enabled as a consequence of drug shortages and ongoing Iranian economic sanctions

-[Health is a fundamental human right](https://www.who.int/mediacentre/news/statements/fundamental-human-right/en/), but the embargo clearly goes against giving people access to life-saving medicine. It brings tears to my eyes to think about people losing a loved one over inability to access a drug or medical device that's no longer available in Iran.

US measures also put pressure on a banking system already strained by the previous sanctions regime before the adoption of the JCPOA in January 2016.

-Unpredictability is only part of the story, in general a high inflation rate means a degradation of life quality over time, and a lower quality of life includes a lack of access to even the most basic needs. It means having to put your children in less qualified schools, it means avoiding doctor appointments by any means necessary, it means cutting corners in every section of your life, it means a less balanced environment to live in, an environment where people get angry more easily since they are under a constant pressure as a cause of their degrading lives. No matter how hard you try, your life quality only goes downhill, never up.

 # Final Message
 
-[Racism](https://en.wikipedia.org/wiki/Racism) is defined as  "prejudice, [discrimination](https://en.wikipedia.org/wiki/Discrimination), or antagonism directed towards other people because they are of a different race or ethnicity". Sanctions, likewise, are a clear case of prejudice, discrimination and antagonism directed towards people because they are born in a certain country, or reside in a certain part of the planet.

-If a person is jailed, or killed because of the color of their skin, you feel furious and protest against the act to show that racism has no place in your country.

It's discrimination on the scale of a whole population of millions. Although the people who are being effected by these sanctions are far away from your home, their misery is caused by your country's policies and actions, and you have the right to stand up against these discriminations.

 What is Objectivity Anyway?

-Is it possible for us to have a view of something without it being part of our experience? It seems not. All that we do, all our views and expressions and our interactions are part of our experience as a person, and it relates to us on an intimate level, which means that everything that we do as individuals is subjective. In that sense, it seems impossible for any individual to be objective, since they will always have some form of inclination about everything.

-> It may be more accurate to think of objectivity as a direction in which the understanding can travel. [...] The process of reduction is a move in the direction of greater objectivity, toward a more accurate view of the real nature of things. This is accomplished by reducing our dependence on individual or species-specific points of view toward the object of investigation.

-We start with our individual perceptions as the most objective view and description, we then move towards descriptions that allow us to agree with other (human) beings, and finally we move towards descriptions that can be verified and agreed upon by other apparatus, although it is important to understand that even the apparatus that we may use to describe things are not necessarily free from bias, since they are created by biased individuals and groups. By now you may notice that if a measuring device is made to be agreeable between a large group of people, it is already more objective than a device made by a single individual! However, absolute objectivity, which we may call "a view from nowhere" may not be attainable by us, because we will always be viewing things from our own perspectives, even if it is a large, collective perspective that we agree on, it is not a view from nowhere.

 Inherently Subjective Things
 ----------------------------
 
-With our definition of objectivity in place, now let's see: is there something that we cannot move towards objectivity about? Yes. That is our personal experiences.
+With our definition of objectivity in place, now let's see: is there something
+that we cannot move towards objectivity about? Yes. That is our personal
+experiences.
 
-See, if there is an attempt to give a more objective description of _my_ personal experience, there will need to be either an agreement among a group of beings about this description of my personal experience, or there should be an apparatus that we can agree on that measures my personal experience. However, my personal experience is personal exactly because it is completely dependent and originated from my perspective alone, and no one else's; and as soon as you try to move towards objectivity by trying to describe this experience in a way that moves away from my person-specific and species-specific standpoint, towards a more agreeable and general description that even non-human beings or apparatus can agree with, you lose the initial personal experience in the process, so you end up with a non-personal description of the experience which misses the point of the actual subjective experience I have.

-So, you can come up with _some_ description of my experience, but you can't actually describe the subjective experience of being me as it really is. The walk towards objectivity requires you to drop the subjectivity of my experience, and hence, some inherently subjective things such as our personal experiences can't be objectified.

->  Experience itself, however, does not seem to fit the pattern. The idea of moving from appearance to reality seems to make no sense here. What is the analogue in this case to pursuing a more objective understanding of the same phenomena by abandoning the initial subjective viewpoint toward them in favor of another that is more objective but concerns the same thing? Certainly it appears unlikely that we will get closer to the real nature of human experience by leaving behind the particularity of our human point of view and striving for a description in terms accessible to beings that could not imagine what it was like to be us. If the subjective character of experience is fully comprehensible only from one point of view, then any shift to greater objectivity that is, less attachment to a specific viewpoint does not take us nearer to the real nature of the phenomenon: it takes us farther away from it. {% cite nagel1974like %}

 So What? (Or: Why is This Important?)
 ----------------------
 
-This realisation means that objectifying people's subjective experiences is not possible, we will never be able to decipher someone's subjective experience of something. This does not mean we should not try to _understand_ people, rather, it means we should always consider that our understanding of someone's subjective experience will never be objective, it will always be merely our perspective of it. When it comes to people's personal experiences, we can't be sure that we are right, the way we are confident we are right after measuring a distance using our agreed-upon metric ruler; when it comes to subjective experiences it's always only a crude approximation.

 TL;DR:
 
-`Box<str>` is a primitive `str` allocated on the heap, whereas `String` is actually a `Vec<u8>`, also allocated on the heap, which allows for efficient removals and appends. `Box<str>` (16 bytes) uses less memory than `String` (24 bytes).

 # Videogaming as an Embodied Activity
 
-This is not a simple question, and our discussion here is not to be taken as granted, of course. There are many complexities involved with attributing something as complex as "embodiment" to an activity as complex as playing videogames. This is a puzzling notion, but nevertheless, it is worth considering and thought.

-Given the framework described, we can now formulate videogaming as an embodied activity. A more trivial example of what we are trying to formulate is driving cars, which is a common example used when talking about embodiment in cognitive science. When we drive a car as a proficient driver, we manoeuvre by considering what we want to do, and acting towards that direct goal without focusing on how we do this by using the gears, the clutch, the brake, pedal and the wheel, etc. We might be taking 3 to 4 actions at the same time, e.g. when reverse turning: brake in, clutch in, wheel to one side, change gears to reverse, look in the mirrors, however we are mostly thinking about where we want to go, not all the details and specifics of our interactions with the car's interface. Similar to the example of the blind man and the stick, the apparatus has become transparent and now our body schema includes the car. We decide we want to reverse and turn to one side, and given our new intentional stance towards the world that is limited and extended using the car, we consider our self to be capable of doing so. The way we question and talk about the world changes, too, we ask "do I fit here?", wondering if we can pass through a narrow passage with the car, we are now embodying a new intentional stance towards the world, and this new body schema is what gets attribution for our action.

-Videogames are similar, with the difference that instead of sitting inside a car that moves spatially in the world, our human body sits in one place, but we still go places in the game-world.

A new intentional stance arises towards the game-world, that is defined by the avatar that we embody in the videogame.

-In these videogames you are allowed to look at the world and your avatar from any place, and given our framework, the camera is now a novel extension to our body-schema.

-This opens up the possibility of a new kind of vision interaction with the world. When the stakes are high, as is the case with e-sports, players strive for the ultimate proficiency with their new body-schema, and the result is ways of using vision that are not usual and can sometimes be cryptic for us. Camera movement of professional players tends to be very fast, and sometimes outright chaotic to an untrained eye since they want to optimise being able to scout for information while still keeping an eye on their avatar, since the avatar is still the most important part of the game, and the free-form camera movement is mostly used similar to a binocular: to scout for information.

 # Further Questions
 
-There is a question to be asked here about how much this technical camera-avatar independence leads to actual camera-avatar independence: do players actually end up with their camera away from their avatar much, or is the camera still in synchrony with the avatar for the majority of the time, but in a manner directly controlled by the player rather than automatically.

-Does the camera-avatar independence affect the embodied experience of playing this videogame, perhaps by making it more difficult to be proficient in the game, it is initially harder to extend your body-schema with this new form of vision, but what happens once you are proficient?

-Competitive e-sports increase the stakes and are motivation for players to strive for utmost proficiency in a videogame, this usually leads to players being very creative and highly skilled in using the interface available to them (e.g. mouse and keyboard or a controller). In case of MOBA games with independent cameras, players reach very high action-per-minute numbers, in the last game of the largest competition for Dota 2, The International 10, the players averaged 303 actions per minute, which is about 5 actions per second, not including camera movements (camera movements are fluid and continuous and are not considered as discrete, hence their exclusion from a numerical value). {% cite dotabuff-true-sight %}

 # Conclusion
 
-Videogames are usually formulated under information-processing cognitive models when studied in cognitive science, however on a closer look, they can be considered an embodied activity given the right framework. Here we consider Merleau-Ponty's intentional stance and body schema as a framework to formulate how a videogame might be considered an embodied activity.

+Merleau-Ponty's intentional stance and body schema as a framework to formulate
+how a videogame might be considered an embodied activity.
 	
-Camera-avatar relations are an important factor affecting our intentional stance in a videogame, and they lend us different body schemas, from first-person and third-person camera views to an independent isometric camera that is controlled by the player. Independent cameras in videogames allow for a novel extension to our body-schema, an apparatus for vision that can move independent of the body.

-There are still many questions left to be explored on the topic, and rightly so, as the notion of videogames as an embodied activity is fairly perplexing and requires a lot more exploration and study until we reach a more holistic understanding of it.

+I realised that my blog and its content, even though very simple and
+lightweight, are only accessible using a full-fledged web browser. I thought it
+would be interesting if my blog posts were available to be read using an even
+simpler interface, cURL!
+
+To make this work, I made a very simple Jekyll plugin that automatically
+generates a "raw" page for every post I create. These raw pages are available by
+prepending `/raw` to the URL of my posts.
+
+Try it out:
+
+```
+curl https://mahdi.blog/raw/raw-permalinks-for-accessibility/
+curl https://mahdi.blog/raw/embodying-the-avatar-videogames/
+curl https://mahdi.blog/raw/rust-box-str-vs-string/
+```
+
+You can get a raw listing of my blog posts at `/raw/`:
+
+```
+curl https://mahdi.blog/raw/
+```
+
+To make this easily readable on small screens and terminals, I used vim's
+text-width setting to make sure my lines do not exceed 80 characters:
+
+```
+:set tw=80
+```
+
+And to reformat my posts, I went over my text lines (I avoided breaking code
+sample lines), and used `gq` to reformat each section.
+
+The source code for my blog is available on my
+[git](https://git.mahdi.blog/mahdi/mahdi.blog) server, you can find the source
+for [the raw
