The NTRU-based scheme offers comparable efficiency to Falcon and Mitaka and a simple implementation without the need of generating the NTRU trapdoor. Compared to the Gaussian-distributed errors in previous algorithms, the deterministic errors have a smaller size, which lead to a substantial gain in security and enables a practically working instantiation.Īs the applications, we present two practically efficient gadget-based signature schemes based on NTRU and Ring-LWE respectively. This ensures the security of the signature applications. We show that for uniformly random targets, the preimage and error distributions are simulatable without knowing the trapdoor. To this end, we develop a compact gadget framework in which the used gadget is a \emph computes the error and then randomly samples the preimage. This work aims to improve the practicality of gadget-based cryptosystems, with a focus on hash-and-sign signatures. For example, the gadget-based signatures have elegant design and capability of extending to more advanced primitives, but they are far less efficient than other lattice-based signatures. However, the practical optimizations and designs of gadget-based schemes generally lag their theoretical constructions. In the past decade, they have been applied to build versatile and powerful cryptosystems. Lattice gadgets and the associated algorithms are the essential building blocks of lattice-based cryptography. Nevertheless, the key recovery in Mitaka requires much more traces than it does in Falcon, due to their different lattice Gaussian samplers. The same leakages exist within the integer Gaussian samplers of Mitaka, and they can also be used to mount key recovery attacks. Furthermore, combining the sign leakage and the aforementioned leakage, one can recover the key with only 45 000 signature measurements in a short time.Īs a by-product, we also extend our power analysis to Mitaka that is a recent variant of Falcon. We also show that this single bit of leakage is in effect enough for practical key recovery: with 170 000 traces one can fully recover the key of Falcon-512 within half an hour. We identify the leakage within the reference implementation of Falcon on an ARM Cortex-M4 STM32F407IGT6 microprocessor. This leakage was exposed in 2018 by Kim and Hong, but it is not considered in the Falcon’s implementation and unexploited for side-channel analysis until now. The analysis relies on the leakage of random sign flip within the integer Gaussian sampling. Our second result is a practical power analysis targeting the integer Gaussian sampler of Falcon. In addition, our approach is robust to inaccurate leakage classification, which is another advantage over parallelepiped-learning attacks. As a comparison, even with 106 traces, the former attack still needs about 1000 hours CPU time of lattice reduction for a full key recovery. Our approach substantially reduces the the requirement of measurements and computation resources: 220 000 traces is sufficient to recover the secret key of Falcon-512 within half an hour with a probability of ≈ 25%. Instead of resorting to the fourth moment as in former parallelepiped-learning attacks, we work with the second order statistics covariance and use its spectral decomposition to recover the secret information. The first result is an improved key recovery exploiting the leakage within the base sampler investigated by Guerreau et al. In this work, we study Falcon’s side-channel resistance by analysing its Gaussian samplers. Due to its low bandwidth and high efficiency, Falcon is seen as an attractive option for quantum-safe embedded systems. Up to now, he has published over 50 international high-level SCI articles with an H-index of 30 and has received numerous awards and honours, including Outstanding Young Scholars from National Natural Science Foundation of China, Macao Science and Technology Award for Postgraduate Research, and the first prize of Baxter China Young Investigator Award.Falcon is one of the three post-quantum signature schemes selected for standardization by NIST.

They are ideal for a hostile tank setting. Be ready to take away other fish from the tank, as a Maroon Clownfish may choose one day that a specific fish needs to go! Maroon Clownfish should not be housed with tame fish such as dartfish, gobies, etc. Females have been noted to hurry to the front of the tank and thrash their pectoral fins about in order to caution visitors of their fearless and savage nature, even picking up and spitting pieces of gravel or rocks. It makes an exciting character in the aquarium setting, but is so hostile that it’s hard to house, even with other damsels. It is one of only a few clowns that can hold its own in a hostile tank. This is an excellent fish for the amateur, as it is extremely rugged, but it can get rather big and is known to be very territorial. Based on their looks, a few of the depictive common names they are referred to as comprise of White Stripe Maroon Clownfish, Yellow stripe Maroon Clownfish and the Gold Stripe Maroon Clownfish, on top of the two designer names of Orange Jaw Purple Maroon Clownfish and Lightning Maroon Clownfish. They are obtainable singly, as well as in couples, however Maroons are generally a bit costlier than most of the other clownfish breeds. Their newly aqua-refined babies are often known as little sparks. These sorts are now being selectively spawned in captivity, however they are fairly pricey. It was gathered from New Guinea from Fisherman’s Island, and it has generated quite a stir in the hobby. But a new variation has also been imported as lately as 2012, and it has bands exchanged with a lightning and netting type patterning. The golden striped variation originates from Sumatra and perhaps even eastern Java. There have been two distinct geographic variants for a long period of time, one with yellowish or golden bars and one with white bars. Mis-barred essentially means the bars are only across the top of the body, and do not extend all the way down the sides. They are accentuated with three vertical bands that can be broad or think, and some specimens will be mis-barred. They can range from dazzling red, orange or maroon, to a purply brown. And just like other clownfish, they have numerous color variety’s. These clowns are extremely similar in shape to the Ocellaris Clownfish and True Percula of the Percula Complex. As with most of the treasures it was created by the dwarves and had runes carved on its point. Such images date back all the way back to Bronze Age rock carvings of a spear god. Images of the god often depicts Odin bearing a spear. Gungnir Gungnir (Old Norse for “Swaying ”) is the name of the mighty spear that belongs to the god Odin. The reason for this may come from the forging of the hammer, when the dwarf working the bellows was bitten in his eye by a gadfly (secretly Loki in disguise) which caused the handle of the hammer to be shortened. Thor requires the gloves to handle his powerful hammer. Járngreipr (Old Norse “iron grippers”) are the iron gloves of the god Thor. The pendants and icons of the hammer were a common symbol of the god of thunder in North European mythologies and are found in burials and other locations. Due to a mishap in its manufacturing it had a characteristically short handle. Snorri Sturluson relates how the hammer was made by the dwarven brothers Eitri and Brokkr. Mjölnir Mjölnir (the name derived from Old German for “grinder” or “crusher”) is one of the most fearsome weapons, capable of leveling mountains. When worn, the belt doubled Thor’s already immense strength. The Prose Edda lists this as one of Thor’s three main possessions, along with the hammer Mjölnir and the iron gloves Járngreipr. Megingjörð The megingjörð (the Old Norse words mean “power-belt”) is a belt worn by the god Thor. I take a look at some of them in this article. These god and goddess owned and used marvelous treasures. They believed in the many gods and goddesses (over 40 possibly) that included Woden (Odin), Thunor (Thor), Heimdall, Freya and Loki. Today I thought I would take a look at some of the treasures which the Norse and Anglo-Germanic gods were said to owned.īefore the coming of Christianity to the English lands the English shared a common mythology and belief structure to the peoples that would later be called Vikings and the Germanic tribes from which they themselves sprang. Then you’ll learn how to connect neighbouring points with polylines to create a “plexus” style effect. A lot of pre-v12 Houdini tutorials rely heavily on the point sop. Vex is designed to be multi-threaded and incredibly fast, so is ideal for manipulating geometry, or writing shaders, or. After some theory he’ll show you how to generate a closed polygon. Vop and vex (wrangles) are two views of the same thing vex is the core language, vops is a node UI to generate vex code without you knowing it. In this tutorial Manuel will walk you through the process of creating geometry with VEX in a wrangle. But you have to know some things about the way Houdini organizes and stores geometry in memory. Most houdini operators have a group selector at the top of their parameters, meaning they'll only affect those components. The closest analogy in maya would be a selection set of verts or faces. A group in houdini is a selection of components, with a name. In the end, there is a practical application of the theory which shows how to create a “plexus” type of effect, connecting neighboring points with poly-lines. Houdini scene: File:groupdeletehou.hipnc. This tutorial is a great walkthrough for the entire process for creating geometry with VEX, in a wrangle. Typically something like this would be using DOPs or dynamics nodes however, Houdini is great for making custom solutions. This tutorial from Chetal Gazdar shows how to create such an effect using only VOPs and a bit of VEX. Some languages like Python do code compilation behind the scene, so you just run the code and get results. Any code written in any programming language needs to be compiled (converted from human-readable form to machine code) and executed. These images have been created by fumbling with text embeddings. The Attribute Wrangle node creates or modifies existing geometry with a code written in VEX language. Manuel covers the theory behind how a computer and application stores information for geometry - Something that is great to know, if you wish to recreate it. There are many ways in Side FX Houdini to handle things like grass and wind. abstract art houdini vex programming procedura. This seems to be verifiably true, watching his latest tutorial that shows you how to create geometry with VEX within Houdini.ĭid you ever wonder how to create polygons and polylines through code in Houdini? Under the short bio for Manuel, it mentions that he “likes to dive deep into the ins & outs of contemporary CG research”. When learning VEX for Houdini one of the first things that is crucial is understanding how to create points and lines, and by lines we mean primitives. 0:00 / 11:12 Volume density waves in Houdini using VEX Matt Taylor Motion 2.39K subscribers Subscribe 8.7K views 3 years ago Finally tutorial number 2 In this tutorial we'll learn how to. Entagma is the labors of Manuel Cassola Merkle and Moritz Schwind. In this fast and quick explainer tutorial, Ill discuss if you need to learn how to code in order to succeed in Houdini. A new site, Entagma, promises a fresh a collection of resources that cover advanced skills in computer graphics. Moreover, evidence suggests that replacing saturated fats with unsaturated ones from foods like nuts, seeds, olives, and fish may reduce your risk of heart disease ( 7). If these levels become too high, your risk of heart disease may increase over time ( 7). In fact, about half of the calories in regular sour cream come from saturated fat.Įxcess intake of saturated fat may cause some people to produce more LDL (bad) cholesterol. Saturated fat is the predominant fat in sour cream. Sour cream may help your body absorb fat-soluble vitamins, and some types harbor probiotics to boost your digestion and immune health.īear in mind that sour cream has its fair share of drawbacks. Thus, many people may be pleased to know that regular sour cream is compliant with a variety of low carb diets, including keto and Atkins. Low in carbsĪlthough nothing is inherently wrong with carbs, low carb diets are quite popular. You can also try fermenting your own sour cream at home. However, some brands, such as Nancy’s, add these microorganisms back into their sour cream after pasteurization so that you can still reap probiotic benefits. Yet, most commercial sour cream is pasteurized to lower the risk of food poisoning, meaning that any live bacteria are destroyed before they make it into the final product. Thus, certain types of sour cream may offer probiotic benefits ( 6). Sour cream is traditionally made by fermenting dairy cream with lactic acid bacteria, which are one of the most common probiotics in food production. Probiotics are live microbes that provide various health benefits, such as improved digestion and immune function, when consumed ( 5). Regular sour cream is primarily composed of fat. Thus, eating them with a source of fat may enhance your body’s absorption. Deficiencies in these vitamins are associated with diseases like diabetes, cancer, and immune disorders ( 4).įat-soluble vitamins are found in a variety of healthy foods, such as fruits and vegetables, but not all of them provide fat on their own. Known collectively as fat-soluble vitamins, they include vitamins A, D, E, and K. May promote absorption of fat-soluble vitaminsĬertain vitamins require a source of fat to be absorbed most effectively in your digestive tract. Plus, since other dairy products are made with all milk components - not just the cream - they provide significantly more protein, carbs, vitamins, and minerals than regular sour cream.Īlthough you shouldn’t rely on sour cream as a primary source of nutrients, it may still support your health in several ways. Its lack of fat reduces the calorie count by about 60% compared with regular, though it may have slightly more carbs depending on the brand ( 3).īecause sour cream is primarily a garnish, it isn’t typically eaten in the same volume as other dairy products like yogurt or milk. Meanwhile, fat-free sour cream is made with skim milk and additives like food starch and gums so that it maintains a creamy consistency. Reduced fat sour cream has a similar nutrient profile but with fewer calories and about 38% less fat ( 2). Thus, it doesn’t usually offer significant amounts of any nutrient.Ī 2-tablespoon (30-gram) serving of regular sour cream provides ( 1):Īs you can see, regular sour cream is fairly high in fat and calories. Sour cream contains many essential nutrients, but serving sizes tend to be small. That’ll allow you to expand your town and attract new citizens.Īs it is, the easiest way to do this is to build houses. With this game, it’s important to keep building. You can do that once your town is more established. Tip: Avoid spending your gold coins on decorations at the beginning as they can get expensive quickly. And if you log into the game for five days in a row, you’ll get a special prize with even more goodies. That’ll give you a good amount of coins each day so that you can expand your city. If you’re lucky, you’ll find a box that contains gold coins.ĭon’t forget to redeem the Daily Bonus as well. For example, an order of 36 carrots is way easier than an order of 8 syrup and 9 popcorn.Īside from completing orders, you can also earn coins from the hot air balloons that appear over your town. Focus on the ones that can be finished quickly-that way, you’ll earn more in a shorter period of time. That’ll ensure that you’re properly rewarded for your hard work.Īlso, avoid orders that involve goods that take more than two hours to produce. Eventually, you’ll need to collect multiple items and depending on what you need, the pay may not be worth your efforts.Īs a general rule, it’s best to reject orders that pay less than 300 coins (assuming that you’re at least level 20). Keep in mind, however, that the difficulty will go up as you complete the requests. The easiest way to earn coins is by completing order requests from the residents of your town. If he is also a singer, a harpsichord-player and a certified plumber, so much the better. Add to these utter dependability and handiness with tools, and season the whole mixture with patience and humour. So then, for a good effectsman we have to find a person of the auditory type, having a sense of rhythm, as much stage sense and experience as possible combined with acting ability, sympathy, and sensitiveness. Here's one of my favorite quotes, taken from the end of the introduction: As you might expect, it's very much of its time, but it contains many gems and would certainly be helpful if you are looking to replicate other sound effects live. In it, he covers creating sound effects ranging from the natural to the mechanical. It is an absolutely lovely book on live sound effects written in the 1930's by a man who was a director at the Old Vic theatre. It's very hard to find as it has been out of print for an incredibly long time, but there are a couple copies floating around, including on.

The first Hill Climb Racing app wasn't bad by any means, but it admittedly looked amateurish. It helps that the developers are fully aware of how hilarious a game like this looks in motion, and have done everything they could to capitalize on that. Alternating between the pedals in rapid order, often in midair, is the only way to keep your balance, and as such, the game can get tense within minutes. Gravity is a harsh mistress in this world she'll try to push you down a mountain one moment, and she'll make you airborne for driving too fast the next. This is partially due to how it rewards skill, but it's mostly because it's so funny to see in action. Needless to say, Hill Climb Racing 2 is tough, but it avoids being frustrating. However, that's about a far as the simplicity goes, for hilly roads and Newtonian forces combine their might to flip you over every step of the way. The controls are simple you have the gas on the right side of your screen which accelerates your ride and moves it forward, and the brake on the left that slows it down and puts it in reverse.

Contrary to a slew of recent misleading media coverage, the climate impacts of streaming video remain relatively modestĪ number of recent media articles, including in the New York Post, CBC, Yahoo, DW, Gizmodo, and BigThink, have repeated a claim that “the emissions generated by watching 30 minutes of Netflix is the same as driving almost 4 miles”. The updated charts and comparisons also include the corrected values published by The Shift Project in June 2020, as well as other recent estimates quoted by the media. As a result, the central IEA estimate for one hour of streaming video in 2019 is now 36gCO2, down from 82gCO2 in the original analysis published in February 2020. Update : The energy intensity figures for data centres and data transmission networks were updated to reflect more recent data and research. But slowing efficiency gains, rebound effects and new demands from emerging technologies, including artificial intelligence (AI) and blockchain, raise increasing concerns about the overall environmental impacts of the sector over the coming decades. The relatively low climate impact of streaming video today is thanks to rapid improvements in the energy efficiency of data centres, networks and devices. These exaggerate the actual climate impact by up 90 times. Yet, contrary to a slew of recent misleading media coverage, the climate impacts of streaming video remain relatively modest, particularly compared to other activities and sectors.ĭrawing on our analysis and other credible sources, we expose the flawed assumptions in one widely reported estimate of the emissions from watching 30 minutes of Netflix.
