2024.11.30 16:24 RemarkablyUn0riginal A question of consumer ethics: in comparison with secondhand wool and leather could it be argued that through the entire production cycle of synthetic materials (for clothing) more suffering is caused?

Essentially, I need a good quality coat - not being able to fit into an older pure woolen one which I will donate. I'd like another wool coat. I understand and accept arguments against the wool industry as it is (in terms of suffering caused, not commodification). I've found a secondhand wool coat. Will I cause more suffering from purchasing a wool coat or a new coat made from synthetic materials - taking into account the entire process of production for the latter?
(I'm aware I could buy a secondhand synthetic coat, but the quality never seems to hold up as well as a well cared for wool coat).
I also need a pair of shoes for a new professional role. Synthetic vegan 'leather' seems to be of poor quality, from what I've read online, and it seems I will need to buy a new pair on an annual/biannual basis - if I haven't been fooled by reviews. I will also need to purchase these shoes at a steep price - I am broke. I can buy a pair of well cared for secondhand leather brogues for a quarter of the price. Which is the option will cause less suffering? Will my purchase of leather shoes legitimise the purchase of new leather?
I'm coming from a utilitarian position and I'm really not looking for deontological arguments, but an argument from a utilitarian position (if you wish to argue normative ethics we can discuss it separately).

2024.11.30 16:24 Acceptable-Ad-5773 What Kanye Could Talk About On Bully

This is sort of in response to a post I saw about how he may not have much to say at this point in his career. From snippets, it sounds like he's taking the 'they tried to cancel me but look how we made it' route but tbh I hope he doesn't overly lean into that. It feels like just a rehash of some ideas touched on in vultures and its especially weird when you got cancelled for a good reason.
Instead here are some subjects I feel he could (but probably won't) rap about on Bully.
• ⁠New Family Dynamic: Maybe some reflection on how he relates to his dad, or alternatively in what ways he hopes to improve compared to him. Also now that some time has passed he might be regretful of the way he handled the split so publicly or he could more clearly flesh out why he made the choices he did.
• ⁠Relationship With God: He’s obviously been a bit rocky with religion the last few years from Jesus Is King to not being on ‘talking terms’ with god to closing the Korea LP with a prayer. He could talk about balancing being a normal human being with a man of God. Accepting he has his flaws and vices but will always keep his faith.
• ⁠Political Issues (EXTREME REACH): Assuming he could discuss them SENSIBLY and genuinely, it would be interesting to see him flesh out some issues he’s genuinely passionate about. Talk about how black artists and athletes get fucked over in contracts by corporations (without blaming it on another ethnic/religious group). Talk about fugaze virtue signalling in media and hollywood especially. Talk about important issues in a sensible manner without delusion and bigotry.
• ⁠Self Reflection & Apology (EXTREME EXTREME EXTREME REACH): I don’t think Ye ever plans on apologising sincerely for what he’s said but if he did, addressing it through music would be the best way to do it. A track or two about how his mental state led him to say and do things to be contrarian or what he thought was right hurt people. How he recognises he needs to take responsibility for his actions and mental health.

Efficient Sampling Techniques for Large Rasters
https://preview.redd.it/vq0206xme24e1.jpg?width=1154&format=pjpg&auto=webp&s=0162085e30cd710dfd1ade3f4fa9e8381c85c8ca

In the world of spatial analysis, sampling points within specific boundaries is a common but sometimes computationally expensive task. For those working with large rasters and vectors, like polygons across an extensive area, this challenge becomes even more pronounced. In the past, many users resorted to clipping the raster to the polygon layer, but as the size of the data grows, this method can quickly become inefficient and resource-intensive. 🔍
Take, for instance, the case of a geospatial analyst working with satellite imagery and land-use data. If the task involves sampling points across large raster datasets within the bounds of disconnected polygons, the traditional clipping method might seem like the only solution. However, with massive datasets, such as 10GB or 20GB rasters, clipping can lead to significant delays and put a strain on processing power. The question arises: is there a more efficient way to achieve this goal? 🌍
Luckily, in R, tools like the Terra package provide an alternative to raster clipping. Using layer bounds, it is possible to sample points within the extent of polygons without needing to modify the raster itself. This approach not only saves time but also reduces memory consumption, making it much more scalable for large projects. With this method, you can still ensure that your random points fall only within the desired polygons without overloading your system. 💡
In this article, we’ll explore how to perform random sampling within polygon bounds using Terra, walking you through the code and highlighting key steps. By the end, you’ll be equipped with a faster and more efficient method for sampling points in R, ensuring that your geospatial analyses are both accurate and resource-friendly. So, let’s dive into this method and see how you can make your sampling process much smoother and more efficient!

How the Scripts Work: Efficient Random Sampling within Polygon Bounds
https://preview.redd.it/li4bl3mne24e1.jpg?width=1125&format=pjpg&auto=webp&s=d7666b401c6952dac98fee5140cb8b807bb4efa8

In the previous examples, the goal was to efficiently sample random points within the polygon bounds of a raster layer, avoiding the computational burden of clipping large rasters. This task is particularly important when working with large datasets in spatial analysis, such as remote sensing data or environmental modeling. The solution provided in R, using the Terra and sf packages, allows for the sampling process to happen within the boundaries of vector polygons, which represent specific geographic areas of interest. The command rast() loads the raster data into R, enabling manipulation and sampling without actually modifying the original raster, ensuring the process remains efficient even with large files.
The first critical step in the script involves using the ext() function from the Terra package to extract the extent of the polygon data. This provides the bounding box, essentially a rectangular window, that defines the area within which the random points should be sampled. For example, in an analysis of land use, the extent would represent the geographical limits of a region, such as a forest area or a city. The bounding box derived from the polygons ensures that only points within these predefined regions are selected, making the analysis specific and meaningful. This approach also saves on computing power by eliminating the need for clipping the raster itself.
The spatSample() function is then used to sample random points from the raster, based on the defined polygon bounds. The function allows us to specify the exact extent of the polygons where the points should appear, thus ensuring that the sample is spatially constrained to the areas of interest. For instance, if the polygons represent different forest patches in a large national park, the random points will only fall within these forest areas, avoiding regions outside the polygon bounds, like water bodies or urban areas. This ensures that the sample is both accurate and relevant to the analysis, without unnecessary data manipulation or memory consumption.
The second solution, which incorporates the sf package, introduces the st_read() and st_transform() functions. These commands allow for vector data to be read into R as spatial features. For example, st_read() is used to import a shapefile containing the polygons that define the sampling areas. Afterward, the st_transform() function ensures that the coordinate reference system (CRS) of the polygons matches that of the raster data. This alignment is crucial for accurate sampling, as mismatched CRS can lead to errors or incorrect point locations. For instance, if the polygon data is in a different projection than the raster, it could result in sampling points outside of the intended area. By transforming the CRS, the solution becomes more robust and universally applicable, regardless of input data projections.
Lastly, the st_sample() function from the sf package is used to generate random points within the polygons. This function is quite powerful because it respects the geometry of the polygons and ensures that the points are spatially distributed within the correct boundaries. In the context of environmental monitoring, if you were studying biodiversity within different ecosystems, you could use this function to sample random points within forest patches, which would then be used for further analysis, such as vegetation surveys or soil sampling. The combination of these optimized commands provides a solid, efficient approach to random sampling within polygon bounds, making it an essential tool for working with large raster and vector datasets in R. 🌍

This approach utilizes the R programming language along with the Terra package, a powerful tool for spatial analysis of raster and vector data. The method aims to randomly sample points within the bounds of multiple disconnected polygons without the need for raster clipping, ensuring better performance when working with large datasets.

Below is a table that describes some of the key R commands used in the previous examples. These commands are critical for efficiently sampling random points within polygon boundaries, focusing on performance optimization and spatial analysis.
Optimizing Random Sampling of Points within Polygon Boundaries

Sampling random points within specific polygon bounds on large raster datasets can be a computationally challenging task. Traditionally, users would clip the raster using the polygons and then sample the points from the clipped data. While this method works, it is resource-intensive and inefficient when dealing with large raster files, especially in remote sensing or environmental modeling. With advancements in spatial analysis packages such as Terra and sf in R, a more optimized approach has emerged. Instead of clipping, we can sample directly within the polygon bounds, reducing unnecessary data processing and memory usage. This approach leverages the bounding box of the polygons to limit the area where random points are sampled, providing a more efficient and scalable solution.
By using the spatSample() function from the Terra package, users can directly sample random points from the raster within the polygon bounds. The function allows the user to specify the number of points to sample and the extent (i.e., the boundary box) within which the sampling will occur. This eliminates the need to manipulate the entire raster, thus saving processing time and system memory. It also ensures that the sampled points are representative of the polygons, which is crucial for studies such as land cover classification or habitat analysis, where only specific areas need to be analyzed. For example, in ecological research, sampling could be restricted to forest areas, excluding water bodies or urban zones, making the analysis more targeted and meaningful.
Another important consideration is how the sf package can be used in conjunction with the Terra package for vector data processing. The st_transform() and st_sample() functions allow for the proper alignment of vector and raster datasets by transforming the projection of the polygons to match the raster's coordinate reference system (CRS). This step is crucial for accurate point sampling since mismatched projections could lead to sampling errors. Once the vector data is properly aligned, random points can be sampled within the polygons using st_sample(). This method is particularly useful when working with polygon shapefiles or other spatial vector formats, offering a more integrated and comprehensive solution for spatial data analysis. 🌲

Don't get me wrong, I do believe that pubs in Ireland are probably the best on the planet overall. But the beestout selection is so repetitive and very rarely has anything from the local area. Even when they do have something local, it will cost a fortune, and you'll be told how that particular brewery is on its last legs and struggling to stay afloat. How do we allow our government for multinationals selling low grade beers at premium prices at the expense of a potentially very lucrative local industry? Have Irish pubs effectively just followed the English model (owned by the drinks company) in a round about fashion?
