Unbounded metric space9/1/2023 Various definability results are proved regarding geodesic rays and. Moreover, in the definition $M=B(a,r)$, one could easily forget that the ball on the right hand side of the equation must be taken with respect to $M$ and not to some larger space, where writing $M\subseteq B(a,r)$ does not allow one to make such a mistake. Background on CAT(k) spaces, asymptotic cones, symmetric spaces, and buildings is provided. However, the supremum norm does not give a norm on the space C ( a, b ) of continuous functions on ( a, b ), for it may contain unbounded functions. Boundary is a distinct concept: for example, a circle in isolation is a boundaryless bounded set, while the half plane is unbounded yet has a boundary. The space C a, b of continuous real-valued functions on a closed and bounded interval is a Banach space, and so a complete metric space, with respect to the supremum norm. The word 'bounded' makes no sense in a general topological space without a corresponding metric. Harsh Reality Memory Matters Memory is not unbounded It must be allocated. Conversely, a set which is not bounded is called unbounded. This coincides with the intuition people want to capture by boundedness, though it is equivalent to other definitions. External - Enough space exists to launch a program, but it is not contiguous. The definition $M\subseteq B(a,r)$ is a good definition for a metric space or subset thereof being bounded. However, one might note that if you want to define a bounded subset $S\subseteq M$, then you would write $S\subseteq B(a,r)$ rather than $S=B(a,r)$, since the ball would be taking place in $M$ rather than intrinsically $S$. Knowing this, the statement that $M\subseteq B(a,r)$ implies that $B(a,r)=M$ since $\subseteq$ is an antisymmetric relation. It is trivial that we have $B(a,r)\subseteq M$ for any $a$ and $r$. In particular, since a ball is defined as Bounded Sets in a Metric Space, two definitions are equivalent. In particular, the metric space ( X, d ) is said to be bounded or unbounded according as the set X is bounded or unbounded.(However, a continuous function must be bounded if its domain is both closed and bounded.) hilbert - Go package for mapping values to and from space-filling curves. | f ( x ) | ≤ M are both continuous, but neither is bounded. cuckoo-filter - Cuckoo filter: a comprehensive cuckoo. In other words, there exists a real number M such that linear operator between two Hilbert spaces X and Y, y 2 Y is given, and x 2 X is. For a different argument: the sequence 1, 2, 3, has no convergent subsequence (and for metric spaces, compact sequentially. Then when metric spaces are introduced, there is a similar theorem about convergent subsequences, but for compact sets. Also, the limit lies in the same set as the elements of the sequence, if the set is closed. In mathematics, a function f defined on some set X with real or complex values is called bounded if the set of its values is bounded. metric smoothing of curves and surfaces de ned by scattered data. R is complete in its standard metric, but not compact. In real analysis, there is a theorem that a bounded sequence has a convergent subsequence. Intuitively, the graph of a bounded function stays within a horizontal band, while the graph of an unbounded function does not.

The Clean Air Acts of 19 were a direct result of this, reducing emissions of black smoke. Combined, this caused poor air quality that was extremely dangerous. In December 1952 London saw what become known as ‘The Great Smog’, during which weather conditions trapped the smoke from coal fires and produced ideal conditions for the formation of a dense fog. It’s been a problem since the onset of the Industrial Revolution in the late 1700’s, which saw an increase in coal burning for industry (for example to fuel factories and steam trains). Smog can turn the sky green, yellow, red, brown, black or grey. This means that industrial areas (which are usually the areas of highest air pollution) are more likely to see thicker fogs, because there are more particles in the air for the water to cling to.įog that mixes with air pollution is often called smog (smoke fog). In industrial areas it’s often particles of air pollution that the water collects around. At the coast the water usually attaches to salt particles in the air. This is because water droplets cling to tiny particles in the air. It’s interesting to note that thicker fogs often form in industrial areas. Water droplets in fog cause poor visibility by reflecting light, which can distort shapes and make it difficult to judge distances. The MET Office refers to thick fog when visibility is below 180m and dense fog when it’s below 50m (that’s the length of the Olympic sized pool we’ve been talking about!). Except for coastal fog, which is more common when warm, moist summer air meets the cold surface of the sea. For this reason, fog is more common in autumn and winter when the ground is coldest. Fog often forms when warm, moist air is cooled by cold surfaces. Clouds form when warm, moist air meets with cooler air flows. Or, how on a cold day your breath forms a mist when you exhale, as your warm breath mixes with the cold air. For example, think about how the water vapour from a hot shower, clings to the cool glass of a mirror as condensation. Water vapour in the air cools to form water droplets. They are the result of warm, moist air being cooled. This is because fog and clouds form in the same way. How much water do you think can be collected from fog? The MET Office website states that ‘if you were to fill an Olympic sized swimming pool with fog and then somehow condense it, you would be left with around 1.25 litres of water (or just over 2 pints).’ĭo you know the difference between mist and fog? It’s visibility! The Met Office states that ‘ If you can see more than 1,000 metres it's called mist, but if it is thicker and the visibility drops below 1,000 metres it's called fog.’ Mist and fog are both formed from water droplets collecting in the air, but mist is less dense (meaning an Olympic sized pool full of mist would provide less water when condensed) this means it can be seen through easier and is less likely to stick around for a long time.įog can also be described as a cloud forming at ground level. Some places call this ‘sky fishing’ or ‘stealing from the sky’. Some parts of the world use nets designed to capture the water droplets of fog, which provides a supply of water in areas that don’t see much rain. I wouldn’t have liked to be crossing roads or surrounded by obstacles I couldn’t see.įog is made of water droplets smaller than rain drops. It was thrilling, but I was on a long, even, mostly empty beach at the time. Have you walked in a thick fog before? I’ve walked into a fog where I could only see about a foot to either side of me. Fog is dangerous when travelling because it causes poor visibility. The MET Office have issued weather warnings for fog for large parts of the UK today.

Space saver stackable washer and dryer8/31/2023 Despite these design concerns, we still give this duo a thumbs up. These machines would measure over 6 feet tall when stacked, so they are taller than other compact stackable models in our roundup. Also as a word of warning for shorter users, it can be a challenge to operate a dryer when in a stacked position, especially if the controls are located at the top of the unit. You will also have to purchase a separate kit to stack these models. We realize this may not be an option for users living in smaller homes or apartments. Of course, the noise could be dampened by closing the laundry room door. But when they were side-by-side, they were surprisingly loud. These items can be thrown into a separate dry cycle on a quick timed dry.ĭuring our testing period, our team member chose not to stack these models, as they would not have fit in her laundry room, so we cannot speak to the noise level of these machines in a stacked configuration. We never had any issues with loads needing multiple cycles to dry, but we did note that some bulkier items like towels and thick cloth diapers were still slightly damp. The dryer has similarly helpful functions like Balance Dry, which help to prevent temperature spikes and keep fabrics cooler during a cycle, and Predictive Dry also more accurately figures out dry times within 90 seconds of starting a load. The washer’s SmartBoost premixing technology fully mixes any HE detergent type (powder, pods, or liquid) with water before dispensing on a load of clothes to ensure optimum stain removal. We found the 15-Minute FastWash and Heavy Duty cycles to be super effective for cleaning poopy cloth diapers and quickly refreshing spit-up-covered baby swaddles. While these machines aren’t equipped with smart technology, they are highly efficient and have incredible stain-fighting capabilities. We had the opportunity to test this washer and dryer set in one of our team member’s homes and neither machine disappointed us. Take a look at our list of impressive, stackable washers and dryers, whether you're short on space or simply want a reliable pair in your laundry room.įinding a stackable washer and dryer that doesn’t compromise on capacity can be a challenge, which is why we love the Electrolux ELFW7637AT Smartboost 4.5-cubic-foot High-Efficiency Stackable Steam Cycle Front Load Washer and ELFE7637AT 8-cubic-foot Stackable Steam Cycle Electric Dryer. To select the top picks for your home, we researched the best models available by evaluating features, capacity, ease of use, and coveted automated maintenance cycles. Luckily, we're not strangers to regular maintenance required for most large appliances or to the washers and dryers that should be on your radar if you're in the market for a stackable set. This is especially true for front-loading washing machines that can start to smell musty after a few months of use. "Make sure to conduct regular maintenance of your machine, including tasks like cleaning your washing machine drum or cleaning the lint drawer of your dryer," advises Jennifer Ahoni, P&G's fabric care principal scientist and laundry expert. Just like their side-by-side counterparts, stacked washers and dryers should be maintained and cleaned thoroughly to optimize long-term performance. The set could include two front-loading models that are installed vertically and can be separated at any time, or it could have the design of a laundry center that seamlessly connects a top-loading washer to a front-loading dryer. But, even if you live in a small space, you typically need both a washer and dryer, which is why many households shop for a space-saving, stackable set.

Ember temperature control mug rating8/31/2023 The LED also changes color to signify different things, so red means low battery, solid white means your ideal temperature has been reached, and blue means it's updating the firmware.īelow the presets, you'll also find a Tea Timer section, which allows you to set an alarm for the perfect brew time. You can switch between Fahrenheit and Celsius, change the brightness of the LED, and set the LED color (I chose purple). Choose your beverage and stick with the preset temperature, or swipe left or right to increase or decrease it to suit your personal preferences. A latte is set to 131 degrees Fahrenheit, for example, while green tea is set to 137 degrees. Tap the arrow at the bottom, and you can see several presets for different drinks. The main screen says Empty until you put something in the mug, then it displays the temperature on a sliding scale along the bottom. You configure your Ember Mug 2 using the mobile app and it's all very straightforward. The Ember Mug 2 removes all doubt by telling you when the ideal temperature has been reached. How soon do you risk a sip? Too keen and you'll be rewarded with a scalded tongue, but leave it too long and you may miss the perfect temperature window when your hot drink is at its most pleasurable to slurp. There's always a gamble in that period after you make a cup of tea or coffee. It's not just about keeping your drink warm. I've gotten so used to it that after just one week of testing, I don't think I can go back to a regular mug. A smart mug may sound ridiculous, and at $99.95, it's not a cheap purchase. The Ember Mug 2 is the top smart mug in our buying guide to coffee mugs because it aims to make your cold tea and coffee woes a thing of the past with temperature controls you can configure from your phone. So what do you do? You can pour it away and make a new cup, or give it a blast in the microwave, but neither is an ideal solution. That hasty glug of forgotten tea or coffee is always unpleasant.

Forspoken graphics modes8/31/2023 As such, I went into the game filled with uncertainty - pre-release media never managed to perfectly convey what the game is about and the demo raised more questions than answers.Īt its core, Forspoken is an open world action RPG with a focus on magic and high-speed traversal. The trailer showcased impressive visuals and imaginative gameplay scenarios but it also raised many questions, and the hype leading up to release has remained somewhat tepid. In that sense, Forspoken melds Japanese design with Western sensibilities to create a unique fusion.ĭeveloped by Luminous Productions - including many of the same people that worked on Final Fantasy 15 - Forspoken is only the second game in 10 years to be powered by Luminous Engine. Powered by Luminous Engine and inspired by the world of Agni's Philosophy, Forspoken channels a different era of Square-Enix, when new concepts flowed freely, bound not by the Finality of its most popular Fantasy series. Now, more than ten years later, this convergence of technology and world building come together in a shipping game: Forspoken. A second demo, known as Witch Chapter 0, was created and shown three years later, focusing on the same lead character while expanding its technology. The demo was called Agni's Philosophy and it was our first taste of the Luminous Engine which would go on to power the gorgeous Final Fantasy 15. Here is a table of every graphics settings option in forspoken.In 2012, Square-Enix unveiled a tech demo designed to showcase what the then next-generation of consoles might be able to deliver from a visual perspective.

Rsa iphone recovery code8/31/2023 Specifically, Duo Push utilizes the native push notifications (APNS, C2DM, etc) to provide real-time notification of transaction and login requests to a user’s smartphone, a secure out-of-band (OOB) communications protocol to display the full verified details of the request to the user, and simple one-touch responses to allow the user to approve or deny the request on the smartphone itself. Just a couple weeks ago, we launched our Duo Push authentication:ĭuo Push leverages the capabilities of modern smartphones to create a more secure and user-friendly two-factor authentication experience. Unfortunately, the use of shared secrets is a necessity for OTP-based authentication, so any and all vendors (RSA, Google, Verisign/Symantec, etc) offering OTP two-factor (whether OATH's HOTP/ TOTP or some other proprietary algorithm) are vulnerable to RSA-style breaches. The other issue that is important to protect against is RSA-style breaches, where the shared secrets used as the seed for OTP-based authentication may be leaked out of a database by an attacker. In the event of a compromise, the integrity of your users' primary credentials remains intact. That is, instead of delivering an on-site hardware/virtual appliance that proxies usernames and passwords, your users' primary credentials are never touched by Duo-controlled code. We already limit our risk and differentiate ourselves from our competitors by maintaining complete independence (none of this pin+passcode garbage) from your primary authentication for our native integrations (eg. The topic of trust is something near and dear to us at Duo, as we've designed our platform from the ground-up to place as minimal trust in our service as necessary and are continually working to further host-proof our service. In RSA's case, they did a lot wrong, which they undoubtedly realize as they churn millions of new SecurID tokens off the assembly lines. The design decisions and mechanisms that help mitigate the risk of a breach, limit its impact, and rapidly recover from it are the most important things to consider. Second, to butcher a Fight Club quote: "On a long enough timeline, everyone gets owned." Even RSA. While RSA's implementation of two-factor may be suboptimal, the event bolsters the argument for deploying two-factor rather than undermining it. The attackers targeting Lockheed Martin and company had to plan an entirely separate operation to compromise RSA's internal secrets to even get their foot in the door of the defense contractors. However, I think there are a couple interesting points that can be drawn from the RSA breach:įirst, the RSA breach has shown that two-factor technology is incredibly effective. We haven't commented much on the RSA breach, primarily because, instead of ambulance chasing, we've been busy working on some technology to prevent RSA-style attacks from impacting our Duo Push authentication, which is the subject of today's post.
