In searching though old company records, Meshes recently uncovered a stack of old sausage recipes from around the world (39 in all), along with 25 general food recipes. But even to keep the grinders at current prices the metal parts have to be ``cast in Taiwan,'' Meshes explains. ``A man wrote from New York City to say that his family bought their first Universal grinder in 1912 for just 87 cents.'' The writer felt that current prices, from $23 to $35 depending on size, were too high. What Meshes describes as ``the new-old love affair'' in the kitchen prompts between 20 and 25 letters a day from users. ``I happen to know,'' Meshes says, ``that the mold for that particular cutter was last used a hundred years ago.'' The modern blade, however, fit the antique.Īpart from visiting trade shows, Meshes relies on word-of-mouth advertising to promote sales. Many people write or stop by to tell Meshes that the machine they now use was first clamped to a table ``in grandma's kitchen.'' A recent letter contained a cutter blade that needed replacing. The introduction of nylon brushes to reduce the wear of metal on metal is the only recent improvement, ``and that is a materials rather than a design change,'' Meshes points out.Ī standard feature of any cast-iron product of simple design, like the hand grinder, is its durability. The original design was so simple and so effective that barely more than three design changes have been made in the machine in the intervening years, ``and those were largely cosmetic,'' Meshes says. She herself has two hand grinders stored away which she hasn't used ``in years.''Īnita Hirsch of the Rodale (Organic Gardening Magazine) test kitchens says that their hand grinder is rarely used, ``except for making chopped liver.'' That is a comment that has been frequently made to Meches, even by poeple who say they are major users of electric food processors.īack in 1842 the first meat grinder, called the Universal as it still is today, was patented in the United States, though Meshes isn't certain that similar machines were not developed independently in other parts of the world. But not, she says, if the electric one ``is on the kitchen counter and you have to fetch the hand grinder from a storage cupboard.'' Jean Hewitt acknowledges that there are some ground-food textures that only a hand grinder will produce, and that in some rare instances using a hand grinder might even be quicker than using an electric one. The trend towards gourmet, make-it-from-scratch cooking - which food editors, among them Jean Hewitt of Family Circle magazine, say started some eight to 10 years ago - has sparked what Meshes describes as a mild resurgence in the use of the hand grinder. Although the demand is hardly overwhelming (sales hover around 50,000 units a year, according to his figures), ``it's consistent.'' Twenty-five years of sales experience convinced him that even in this age of push-button convenience there should be a steady demand for the hand-operated grinder. Meshes was convinced he wouldn't lose by buying the rights to this nearly 150-year old invention. While there was a good deal of nostalgia behind the decision, Mr. So he made up his mind: He would buy up the rights to its manufacture. As he saw it, an American original was threatened with extinction. When James Meshes heard the news two years ago that the Universal grinder - that hand-operated forerunner of today's motorized food processor - would soon be pulled from the market, his reaction was one of dismay.

"It took me about 4 years to get the product off the ground," Orion admitted, with the first two years committed strictly to the product's design and color. Germaphobes will appreciate the seamless, uncomplicated design of a swing door refrigerator.Initially a collaboration between Orion and his aunt and uncle, who bankrolled the business, the company experienced what can best be described as a soft launch. This may seem like a small detail, but refrigerator handles are notorious germ hot-spots, and that number only doubles when you have two refrigerator doors. Single-door fridges are usually much easier to close so you won’t ever have to worry about if you properly shut it. Keep in mind though that swing doors take up more room than their French door counterparts. Swing Door Easier to close.įrench-door fridges oftentimes need to pushed closed. Most of the biggest models on the market are made with French doors, allowing you to size up to have a bit more room to store and organize food or beverages. More room to organizeĪ French-door refrigerator has multiple tiers and drawers that allow you to use either the width of the fridge in its entirety, or split up items into perfectly organized sections inside of the refrigerator. With French doors, you have the option of opening only one door at a time, letting out less cold air and using less energy. Whenever a refrigerator door is opened, cold air is let out, causing the machine to work harder to keep everything inside at the designated cool temperature. It’s an easy way to give VIP placement to your most accessed foods and beverages. With the fridge on the top, you’ll be able to see your produce right when you open the doors, without having to bend down uncomfortably. Unlike other styles of refrigerators, French door fridges feature the freezer on the bottom, usually as a pull-out drawer. This is better for kitchens with limited space, meaning you won’t have such a tight squeeze behind you when you maneuver around the most-utilized room in the house. With two doors swinging in opposite directions instead of one, wide-swinging door, the clearance is much more narrow on a French door fridge. Two doors, or one door? That is the question. French Doors or Swing Doors: Which is Right for Your Kitchen? When the freezer is on the bottom, there are often organizing baskets or shelves to help you keep everything in order, as well as shelves on the door for even more well-organized food storage. Produce and beverages are clearly on display without having to hunch or bend over to sift through lower shelves. With a freezer on the bottom, the refrigerator sits at eye level, making for easier access to your most utilized part of the appliance. Bottom Freezer Puts the fridge at eye level. Drawer freezers can sometimes feel small with limited storage, while top freezers evoke the feeling of a wide open space to store your essentials and frozen treats. When the freezer is on the top of the refrigerator, there is typically more usable space to store your favorite frozen goods. While that might not effect your energy bill significantly, you can have peace of mind that you are doing your part to reduce electricity consumption. Department of Energy says that refrigerators with top freezers us 10 to 25% less energy than appliances with bottom freezers. While all appliances have varying Energy Star ratings, it’s typically a safe bet that a top-freezer is more energy efficient in your home. Top Freezer or Bottom Freezer: Which is right for your kitchen?įreeze up top, or down below? Top Freezer More energy efficient. Crisp, modern lines, silver trim, and bold colors make functionality feel fabulous. The Big Chill Pro Line combines the best in present-day professional performance and contemporary design. Ghost of Tsushima doesn’t falter in that department and is a more than fitting swan song for the PlayStation 4 era. This level of breathtaking spectacle and irrefutable quality that has defined PlayStation Studios for a generation or more. Riding into battle on horseback to defeat a seemingly immovable force is the kind of scene that will send chills down the back of everyone who plays it. For all of the game’s sense of scale and cinematic sweep, these are superficial aesthetics that come at the expense of gameplay.Set in a fictional 13th Century Japan, Ghost of Tsushima is beautiful and brutal from the very beginning. Choosing this setting lets you play the game like a classic black-and-white samurai movie (even if I must argue that Kurosawa’s greatest masterpiece is Ran, which was shot in colour), which looks terrific until you find yourself lost among the crowd or fail to read the signals to dodge or parry, which appear as coloured glints on an enemy’s weapon. The fundamental problem with Tsushima can be best summed up by its Kurosawa mode. There are interesting ideas such as learning to use different stances against specific enemy types, but you’ll also have to fight against the absence of a manual targeting system and a wayward camera more interested in spectacle than function. It’s at its best when you’re fighting in one-on-one duels set to an epic backdrop, or when challenging your first enemy to a Stand-off with the same tension of a showdown in a Western.īut these are also just a fraction of your encounters since most of Tsushima‘s combat involves taking on mobs that are in turn messy and an irritating exercise in attrition. And in the year of our Lord 2020, why are there still tailing missions?įor players put off by the masochistic difficulty of Nioh or Sekiro, the good news is that combat is on the more forgiving side, where kills and parries are rewarded with resolve gauges that can be spent on healing or special attacks. Yet even though you’re supposed to be able to mix up samurai and ghost playstyles, you’re also frequently forced into stealth situations with insta-fail penalties. Worse are the hackneyed stealth mechanics, which you’ll find yourself using just to alleviate from overwhelming combat situations. Traversal feels straight out of an Uncharted game, where climbing cliffs or using a grapple hook have obvious prescribed paths – hardly what you’d expect in an open world game. This is most apparent when you’re surveying an enemy encampment, which initially seems like it’s going to give you multiple options only for it to fall to one set solution. Yet the missions themselves are rigidly linear in design. But it’s an indecisive approach, where sometimes the lack of navigation has you running around lost, while in another instance the wind blows aggressively against you when you deviate just slightly off course.īetween the main objective, you’ll discover secrets, liberate villages, and more interestingly help allies in their own tales, many which run in parallel to the campaign. It does try to remove the usual open world clutter by having an unsubtle wind guide you to your objective instead of waypoints, while speaking to people might alert you to points of interest that appear on the world map.

While it is widely accepted that the probability of having rogue code intentionally injected by the third-party is low, there are still cases of malicious injections in third-party code after the organization's servers were compromised (ex: Yahoo, January 2014). As the client reaches the hosting website/application, this third-party code gets executed, thus granting the third-party the exact same privileges that were granted to the user (similar to XSS attacks).Īny testing performed prior to entering production loses some of its validity, including AST testing ( IAST, RAST, SAST, DAST, etc.). This risk arises from the fact that third-party JavaScript code is rarely reviewed by the invoking party prior to its integration into a website/application. Risk 2: Execution of arbitrary code on client systems ¶ Typical defenses include, but are not restricted to: in-house script mirroring (to prevent alterations by 3rd parties), sub-resource integrity (to enable browser-level interception) and secure transmission of the third-party code (to prevent modifications while in-transit). This risk arises from the fact that there is usually no guaranty that the code hosted at the third-party will remain the same as seen from the developers and testers: new features may be pushed in the third-party code at any time, thus potentially breaking the interface or data-flows and exposing the availability of your application to its users/customers. Risk 1: Loss of control over changes to the client application ¶
We can set up a Hyper key by going through several steps using Karabiner Elements and Hammerspoon. Win:setFullscreen(not win:isFullscreen()) Open up Karabiner Elements and add the following rule to Simple Modifications:Īlternatively, you can add the following to the "simple modifications" section in your ~/.config/karabiner/karabiner/karabiner.json file, which can help if you want to add the configuration to your dotfiles. Remapping CAPS LOCK with Karabiner Elements Prerequisitesįirst download Karabiner Elements and Hammerspoon from their pages or by using Homebrew: brew cask install hammerspoonġ. In our approach we will also be using Karabiner Elements for the initial key remapping, but we will be extending this functionality using Hammerspoon. If you don't, a simpler approach using only Karabiner Elements might be better. This is why I recommend the Hammerspoon approach if you have programming or technical experience. However, Hammerspoon gives you a lot of power in terms of automation and customisation tools. Let me start by saying that there are multiple ways to set up a Hyper key, and our Hammerspoon approach is not the most simple one. In this guide we will be rebinding the CAPS LOCK key, since this is one of the least used and most redundant keys on the keyboard. The best solution to this is using a key that has relatively little use in day to day life, and rebind this as a Hyper key. By setting up such a key, we make sure that we can always count on our global shortcuts to work, no matter what application we're using.īut how do we do this? All keys on the keyboard have their use, and we can't really add any new ones. The Hyper KeyĪ Hyper key is a special key that is reserved only for these global shortcuts, to keep it completely separate from our regular environment and applications. To overcome these issues, we will be setting up a so-called Hyper key, a special key reserved only for global shortcuts. However, the reason that most applications don't do this is because it is highly impractical to press ⌥⌃⌘⇧ at the same time. One way to do this is using all modifier keys for these shortcuts, since most applications don't use all modifier keys at once. In order to make sure that we can always access this functionality we need to bind it to global shortcuts, of which we know that they are not used by other applications. For some tasks this can be acceptable, but there is definitely some functionality that needs to work in all contexts, like resizing windows, opening certain applications, or locking your screen. Every application has their own shortcuts, making it very likely that some of them overlap. This has happened to me on multiple occasions. Wait, why did I move to the next tab in my editor?' 'I will just move my active window to the right, using ⌥⌘→.

In his 1968 book Nightwatchmen of the Bush and Plain, Australian naturalist David Fleay observed that the boobooks from Tasmania more closely resembled those of New Zealand than those from mainland Australia, though he followed Mees in treating them as a single species. In his 1964 review of Australian owls, Mees treated Australian and New Zealand boobooks, along with several taxa from Indonesia and Papua New Guinea, as one species- Ninox novaeseelandiae-with 16 subspecies. ĭutch naturalist Gerlof Mees and German evolutionary biologist Ernst Mayr regarded the taxonomy of the boobook owl complex as extremely challenging, the latter remarking in 1943 that it was "one of the most difficult problems I have ever encountered". In the Yuwaaliyaay dialect of the Gamilaraay language of southeastern Australia, the Australian boobook is guurrguurr. The Ngarluma people of the western Pilbara knew it as gurrgumarlu. Alternative common names include spotted owl and brown owl. He added, "The settlers in New South Wales are led away by the idea that everything is the reverse in that country to what it is in England and the Cuckoo, as they call this bird, singing by night, is one of the instances they point out." Gould recorded local aboriginal names: Goor-goor-da (Western Australia), Mel-in-de-ye (Port Essington), and Koor-koo (South Australia). William Dawes recorded the name bōkbōk "an owl" in 1790 or 1791, in his transcription of the Dharug language, and English explorer George Caley had recorded the native name as buck-buck during the earliest days of the colony, reporting that early settlers had called it cuckoo owl as its call was reminiscent of the common cuckoo. The common name comes from the two-tone call of the bird, and has also been transcribed as "mopoke". Īustralian boobook has been designated the official name by the International Ornithological Committee, changed from "southern boobook" in 2019 with the separation of some Indonesian subspecies. Meanwhile, in India, English naturalist Brian Houghton Hodgson had established the genus Ninox in 1837, and his countryman Edward Blyth placed the Australian boobook in the new genus in 1849. maculatus from southeastern Australia and Tasmania. boobook, which is widespread across the Australian mainland and Tasmania, and S. In his 1865 Handbook to the Birds of Australia, Gould recognised three species, all of which he placed in the genus Spiloglaux: S. German naturalist Johann Jakob Kaup classified the two taxa into subgenus Spiloglaux of a new genus Ieraglaux in 1852, renaming S. John Gould described Athene marmorata in 1846 from a specimen in South Australia. The species description was based on a painting by Thomas Watling of a bird-the holotype-in the Sydney district in the 1790s. 1790 painting by Thomas Watling on which Latham's description is basedĮnglish ornithologist John Latham described the boobook owl as Strix boobook in 1801, writing about it in English, before giving it its scientific name, taking its species epithet from a local Dharug word for the bird. The International Union for Conservation of Nature has assessed the Australian boobook as being of least concern on account of its large range and apparently stable population. Breeding takes place from late winter to early summer, using tree hollows as nesting sites. The Australian boobook feeds on insects and small vertebrates, hunting by pouncing on them from tree perches. It is generally nocturnal, though sometimes it is active at dawn and dusk, retiring to roost in secluded spots in the foliage of trees. The smallest owl on the Australian mainland, the Australian boobook is 27 to 36 cm (10.5 to 14 in) long, with predominantly dark-brown plumage with prominent pale spots. Eight subspecies of the Australian boobook are recognized, with three further subspecies being reclassified as separate species in 2019 due to their distinctive calls and genetics. Its name is derived from its two-tone boo-book call. Described by John Latham in 1801, it was generally considered to be the same species as the morepork of New Zealand until 1999. The Australian boobook ( Ninox boobook), which is known in some regions as the mopoke, is a species of owl native to mainland Australia, southern New Guinea, the island of Timor, and the Sunda Islands. Spiloglaux boobook parocellata Mathews, 1946. The experimental results of this method on large search spaces demonstrate that the single instance of large problems are solved substantially faster Up to the point when the instance is solved in one sub-thread. The total time by which we evaluate this process is the sum of the times used by both threads Which uses the new heuristic to try to solve the instance. When a new heuristic is learned in the learning thread, an additional solving sub-thread is started The first solving sub-thread aims at solving the instance using the initial heuristic. The solving thread is split up into sub-threads. We alternate between the execution of two threads, namely the learning thread (to learn better heuristics) and the solving thread (to solve the test instance). To make the process efficient when only a single test instance needs to be solved, we lookįor a balance in the time spent on learning better heuristics and the time needed to solve the test instance using the current set of learned heuristics. The total time for the bootstrap process to create strong heuristics for large problems is several days. Heuristics that allow IDA* to solve randomly generated problem instances quickly with solutions very close to optimal. Until a sufficiently strong heuristic is produced.Ģ4-sliding tile puzzles, the 17-, 24-, and 35-pancake puzzles, Rubik's Cube, and the 15- and 20-blocks world. To generate a sequence of heuristics from a given weak heuristic We investigate the use of machine learning to create effective Author / Creator Jabbari Arfaee, Shahab.However, in other problems, these distances might not induce an admissible heuristic.Bootstrap Learning of Heuristic Functions For example, in the case of the Fifteen Puzzle problem, both Manhattan and the Hamming distances are admissible heuristics. The admissibility of a heuristic depends on the problem. of the cited book where an example that attempts to show this is given. Then A* with the evaluation function $f_1$ is more informed than A* with $f_2$ if, for all non-goal nodes $n$, $h_1(n) > h_2(n)$. Which admissible heuristic is thus more informed? Consider two versions of A*, each with a different admissible heuristic function This evaluation function corresponds to the evaluation function of the uniform-cost search algorithm, which is an uninformed-search algorithm (as opposed to A*, which, nonetheless, is considered an informed-search algorithm). However, in this case, the only actual information that is used to choose the next node to expand is only based on $g(n)$, that is, $f(n) = g(n)$. For instance, a heuristic function that is trivially admissible is $h(n) = 0, \forall n$. However, not all admissible heuristics give the same information, so not all admissible heuristics are equally efficient. In section 2.4 of the book Principles of Artificial Intelligence (1982), Nils J. Given that the goal is to find the cheapest path from a start to a goal node, intuitively, an admissible heuristic is an optimistic predictive function.Ī* is guaranteed to find the optimal solution (or path) if it uses an admissible heuristic. Therefore, an admissible heuristic $h$ satisfies $h(n) \leq h^*(n), \forall n$. An admissible heuristic function is a heuristic function that does not overestimate the cost to reach the goal node, that is, it estimates a cost to reach a goal that is smaller or equal to the cheapest path from $n$, which is denoted by $h^*(n)$. However, one of these paths is the cheapest path. There is potentially more than one path to the goal from a given node $n$. Where $g(n)$ is the length (or cost) of the cheapest path from the start node to the current node $n$ and $h(n)$ is the heuristic function that estimates the cost of the cheapest path from current node $n$ to goal node. In the A* algorithm, at each iteration, a node is chosen which minimizes a certain function, called the evaluation function, which, in the case of A*, is defined as |
