asdf recognizes where you are in a directory or project and decides which version of a given toolset is appropriate for that. asdf is primarily a version manager that handles automatic versioning. asdf - The (easy) version manager □Īsdf may be an unassuming or even uninspired name, but it’s a perfect nod to how transparent and accessible it can be as a developer’s tool. There are other alternatives like the Nix Package Manager, but today we’re going to look at asdf as a small but mighty tool that’s especially useful for version management of local development environments. What I’m getting at here is that with the help of a so-called version manager like asdf you’ve got exactly one software tool with which you can bypass this operational overhead.Ī version manager solves one of the most tedious problems of every developer’s daily business, namely the harmonization of the developer environment. It is precisely in such situations that alternative methods provide a remedy. However, with environmental isolation via hardware or OS-level virtualization, there is still a lot of operational overhead involved. Package managers can perform this function, provided that no manual installation steps are used to manage them. A mechanism is needed to manage these packages. which software packages are installed, are paramount. Nonetheless, within a virtualized environment, the prevailing conditions, i.e. This is colloquially called containerization. The next step was virtualization, when isolation of the environment became possible at the operating system level. Of course, I am saying this in a very simplified way and leaving out many sub-concepts so as not to have to go into too much detail. There’s a need to isolate certain aspects of a given system in such a way that something can be easily replicated again in order to then achieve a desired end state without being influenced by external factors.įirst, entire operating systems were isolated and called hardware virtualization. Exactly this context isolation is a driver of many thrusts in the IT world. This assumes that contexts can be isolated. Possibilities of context switching ↔️īefore you can switch from one context to another, two contexts must be able to exist in parallel and independently of each other. In addition to the fact that a developer has to deliver results, he also has the obligation of leaving behind an understandable, maintainable codebase. The life of a developer is not always easy.

We hoped for a mousse but got a fluffy sauce instead. Our attempt at making a banana pudding mousse using our own ingenuity and a packaged pudding was a little less than successful. Maple syrup was a favorite, but we also tried some fruity syrups, and of course, we added plenty of vanilla to one batch. Plain whipped cream took on a slight sweetness, so we didn’t even need sugar, while flavored whipped creams were a lot of fun to experiment with. We actually found that our favorite thing to make in this whipper was-wait for it-whipped cream. While most whippers include a small cap that covers the nitrous port after the nitrous is injected, this whipper does not have a port cover. In reality, we chose one tip and used it until the cream was gone, and we eventually figured out that we didn’t need to screw the nozzle on quite as tight, so it was easier to remove. However, this could be awkward if we wanted to switch tips back and forth a lot while the whipper was full. It wasn’t actually stuck-we simply had to hold an internal nut as we unscrewed the tip. While the nozzles fit easily onto the body of the whipper, we found that sometimes the nozzle didn’t want to unscrew. This whipper includes two different decorator nozzles which are much like the tips you’d use with a pastry bag, for a little variety in whipped cream design. The whipper is turned nozzle-down, and the lever is pressed to dispense the cream onto pies, waffles, and ice cream. A shake of the whipper distributes the gas in the canister, and it’s ready to serve. The charger holder simply screws onto the head, and a pin pierces the charger with not much effort. We chose a decorator nozzle and attached that, then we used the charger holder to send the nitrous from the small charger (purchased separately) into the cream. Setup was easy: All we had to do was fill it with the proper amount of cream (and sometimes we added a bit of powdered sugar, vanilla extract, maple syrup, or even a little bourbon), then we screwed the head onto the body of the whipper. This type of cream whipper is much like the cans of refrigerated whipped cream that you can find in a grocery store, but we love the idea that we can customize our whipped cream with different flavors and adjust the sweetness to our taste. Please Note: To prolong longevity of your product, we recommend that you regularly wipe with a cloth and then pre oil the thread with food grade oil, such as olive oil or sunflower oil.The Spruce Eats / Donna Currie Setup: Simple Once you’re finished whipping up tasty treats, your dispenser comes with a handy nozzle cleaning brush for total convenience. Be sure to never overfill your canister.Ĭomes complete with 3 different decorating nozzles to give you total control over the finished look. Generous 500ml dispenser capacity allows you to whip us as much or as little as you need. Robust aluminium charger holder (compatible with all makes of N20 chargers) and durable dispenser – much stronger than the alternative plastic designs available. Simply pour in fresh, chilled, heavy or double cream and see it transform in minutes. Perfect for topping off coffee, cakes, pastries or to create a sweet mousse-style dessert. At the quick push of a lever, you can whip up the airiest cream. When a serial killer in Chicago begins embalming victims, Zoey, along with agent Tatum Gray, are brought in to help local police stop the sick and twisted killer before it’s too late. She loves what she does for a living, which allows her to get inside the sick and twisted minds of psychopaths and unlock their motivations in hopes of helping the FBI identify them. Zoe Bentley, a forensic psychologist who consults for the FBI, has a unique connection to her job. Và liệu có thể chặn đứng thứ trò chơi kinh hoàng mà ngay cả tên sát nhân ấy vẫn chưa biết kết thúc thực sự của của nó sẽ là gì?Ī Killer’s Mind is an entertaining, easy to read thriller about “the corniest serial killer ever.” This book is full of snarky characters, wacky murderers, and quirky characters (including a cat and fish). Liệu kẻ giết người vốn dĩ là 1 con quái vật? Và đột nhiên, kẻ đi săn trở thành con mồi! Không chỉ vậy, dòng truyện dần hé lộ quá khứ kinh hoàng của Zoe về ba phong bì đáng ngờ để lại hiện trường: những mối liên hệ kinh khủng, những nỗi sợ quẩn quanh chưa kịp chợp mắt cùng những án mạng dã man trong quá khứ mang tên "Chưa kết án". Kết cục chung cho những người phụ nữ đáng thương này sẽ được phát hiện trong tình trạng lõa thể với một tư thế lạ lùng ngỡ như hệt… vẫn còn sống! Từ đây, FBI vào cuộc và triệu tập nhà tâm lý học pháp chứng Zoe Bentley và đặc vụ Tatum Gray để bắt tay nhau giải quyết vụ án chấn động kinh hoàng, thậm chí phải cùng nhau dấn sâu vào tâm trí của một kẻ sát nhân bệnh hoạn, thích siết cổ phụ nữ, giao hợp với họ và cuối cùng sử dụng phooc-môn ướp xác họ. Câu chuyện bắt đầu trở nên nghiêm trọng khi thi thể của phụ nữ liên tục được người dân phát hiện tại các địa điểm công cộng. Within the early arena of limited variables we can more efficient and effectively build automaticity and cement foundational concepts that can indeed roll forward into more complex versions of the activity we are practicing. As you know, effective learning techniques involve a rational sequence of developing simple concrete concepts/skills and rolling them forward into complex, composite ones. It may not seem obvious when looking at a polished tonal representation that seems bereft of all line-but at the very least, it may serve as an invaluable conceptual scaffolding amid such an effort.Īdditionally, I would address the issue of drawing-as-a-necessary-precursor-to-painting in a similar way (that it may not seem directly applicable in some contexts.) While I wouldn’t call it absolutely necessary- learning most representational concepts with limited dry media prior to painting allows one to focus on fewer variables at the onset. Waichulis_Symbiosis_Bill Detail.jpg 864×559 308 KB Painting up lines over this region (which are then blended) but which curve around the shape of this part of the face in the way I know they would. Instinctively I have gone back to using the ‘contour method’. I think I’ve largely answered my own question here, but wanted to post this anyway for later reference.įinally, in two portraits I’ve recently been doing, the following problem has arisen: for that part of the face between eye and eyebrow, I have been unable to comprehend a shift in tone, nor either to analyse the shape of this part of the face and how it should be behaving under chiaroscuro. Whereas with drawing, because everything is reduced to black and white, you can stick to the method of ‘draw the tone you see’. I realised this when trying to paint an apple. Because painting naturally employs colour, it immediately forces you to try and comprehend chiaroscuro, without which you can find yourself all at sea trying to create dimensionfull objects. One corollary of all of this, is that I think it’s silly to believe that drawing is a necessary precursor to painting, since I think in some ways it might retard development. But probably the author as well was suffering from some form of cognitive dissonance on this issue, in suggesting chiaroscuro be used for the sphere and the ‘contour method’ for cylinders. I think it’s testament to my poor understanding (and indeed the poor exchange of knowledge in art in general) that I didn’t in any way grasp the significance of the ball drawing – not understanding that chiaroscuro applies to all objects not just perfect spheres. A book in which he also showed us chiaroscuro for the sphere. I should explain that I believe this principle was taught in the excellent book of J.D. So in some sense part of what conveys that these objects are 3 dimensional is how surface features curve around the body of the object.īut for a smooth billiard ball I don’t think the contour method would be of any use whatsoever. In fact even apples sometimes possess these lines. The same is true with blemishes on the face that will change in shape, size and distribution according to the curvature of the face. It seems to me that actually it’s not without merit in the sense that if we took a human finger for example, there are actually natural lines on it, which fold around the cylindrical surface of the finger. So here’s the thing: it seems obvious to me that the illusion created by chiaroscuro is vastly superior to that created by this ‘contour method’.īut what I’d like to know is, is the ‘contour’ method totally without merit? And if so, why did I ever start using it? Transfer your contacts from and to iPhone, or sync contacts from old iPhone to the new one.
