New smartasset 110m ttv capital 1b5/16/2023 Securities and Exchange Commission ( SEC) showed.” The decision was made during Aurora’s shareholder’s meeting held on February 24, filings with the U.S. The deadline for the merger is now September. extended the deadline to complete its merger with struggling digital mortgage lender for the third time. Meanwhile, speaking of ’s SPAC filing, HousingWire reported last week that “blank-check firm Aurora Acquisition Corp. Needless to say, we are all super curious to see how this ends up panning out and I plan to check back in about it in a few months. Tacking on another 2.5% pushes someone into the 8% range. Mortgage interest rates are already high enough these days - hovering around 6%. What if the shares drop in value? How does it even work? Who even has enough vested equity to use as collateral? On top of that, says it will charge 0.25% to 2.5% higher interest rates for employees who choose to purchase a home this way. A very quick Google search on the part of TC senior reporter Rebecca Szkutak turned up at least two other online mortgage lenders who are also AWS customers, so surely the retail giant had other options.īeyond that, the idea of giving employees the option to use vested equity toward the purchase of a home just doesn’t….seem very appealing. But he never specifically answered, “Why ?” The fintech itself noted that it has been an Amazon Web Services customer since 2015 and its loan-origination system is powered entirely by the software. And the spokesperson told me lots of things about how the company wanted to provide all sorts of wellness benefits to its employees and this fit into that thesis. So why would Amazon want to be associated with, and connect its own employees to, a company that appears to be far from growing and has a less-than-stellar reputation? Well, we asked Amazon just that (not in those exact words, of course). also made headlines last July when it appeared to still be moving forward with its SPAC filing despite lackluster performance of blank-check combination debuts. The company’s reputation also took a huge hit over the manner in which it conducted numerous rounds of mass layoffs, which also resulted in an executive exodus. Then in the first quarter of 2022 alone, recorded a staggering net loss of $327.7 million, according to an SEC filing. Last May, TechCrunch reported on a filing that revealed that had swung to a loss of more than $300 million in 2021 after a rapid-fire decline in business brought on largely by a slowdown in the housing market and a surge in mortgage interest rates. For the unfamiliar, the fintech company has had its fair share of struggles that have cast doubt on its future. The news, quite frankly, came as a bit of a shock to those of us who have been following the goings-on at. Unique about the program, according to, is that employees will have the ability to finance their homes without actually selling their shares, only needing to pledge vested equity. Amazon employees in Florida, New York and Washington State will be the first to try the tool. Specifically, announced it was launching Equity Unlocker, a program that allows employees to use their vested equity as collateral for a down payment when trying to buy homes.

It can help establish a positive credit history. It will demonstrate you can manage credit. Suppose you use PayPal Credit responsibly, making timely payments and paying more than the minimum payment. The difference is that you can use it to make online payments without carrying a physical card. Using PayPal or the PayPal Credit option is comparable to a credit card account. PayPal Credit provides you with a line of credit that you can use for online purchases and money transfers. However, responsible use of PayPal Credit can improve your credit score. Because PayPal Credit reports to credit bureaus, your credit score may be affected. Let’s examine how using PayPal Credit can impact your credit score. Impact of PayPal Credit on Your Credit Score It contains details about your credit accounts, outstanding balances, and payment history. Your credit history is the most influential factor in determining your credit score. These factors include your credit history, credit utilisation rate, payment history, credit history length, types of used credit, and new credit. Several variables affect your credit score. Lenders use credit scores to assess the risk of lending a person money.Ī higher credit score indicates a lower default risk, whereas a lower credit score indicates a higher default risk. Definition of a Credit ScoreĪ credit score is an indicator of a person’s creditworthiness based on their credit history and other factors that influence creditworthiness. Your credit score is determined by your credit history, credit utilisation rate, and other factors that affect your creditworthiness. Your credit score represents your creditworthiness numerically. T he PayPal Rewards Card will offer another safe and rewarding way for Australians to purchase goods and services in their everyday lives, creating a seamless shopping experience across the online and physical worlds.”Īpplications for the PayPal Rewards Card will be open from mid July 2021.Before discussing how PayPal Credit affects your credit score, let’s define your credit score. “This is just one of the ways we are continuing to enhance the choice and flexibility we offer our customers for how they prefer to pay. “ Our customers have been telling us they want to take PayPal with them into physical stores for some time,” said Andrew. The PayPal Rewards Card will appear in a consumer’s PayPal wallet immediately following approval, ready to use for online purchases before the physical card is delivered to their door. Spending and reward point balance can be tracked through the PayPal app, allowing consumers to manage their account with ease.Īll eligible purchases with the PayPal Rewards Card will be covered by Visa’s Zero Liability policy, while eligible payments made online using PayPal will also be covered by PayPal’s Buyer Protection policy. Rewards points can be redeemed for eligible purchases when checking out with PayPal online, or applied to a recent PayPal Rewards Card purchase to offset the cost, providing maximum flexibility for how consumers use their rewards. In addition to this new card offering more flexible rewards, it also provides a secure, seamless and convenient everyday payment experience for today’s connected and digital-savvy consumer.” The PayPal Rewards Card can be used globally anywhere Visa is accepted and earns points with every eligible purchase.Īxel Boye-Moller, Visa’s Head of Product for Australia, New Zealand and South Pacific said: “Visa is thrilled to be the payments network collaborating with PayPal on their first consumer credit card in Australia. The pandemic has made the value of flexible rewards even clearer, as many Australians have been left with travel-related points they haven’t been able to use the way they would like to due to safety concerns and border restrictions.” The PayPal Rewards card, launching in July 2021, will have zero annual fees and uncapped rewards points, with the ability for consumers to earn points with every eligible purchase and redeem points at more than 750,000 PayPal businesses globally, including more than 300,000 PayPal businesses in Australia.Īndrew Toon, General Manager, Payments, PayPal Australia said: “Consumers have said they want a flexible rewards program with points they can redeem however they’d like.

Rick the walking dead butchers5/16/2023 It’s the banality of evil but in some ways, it’s another day at the office at Terminus. There is a gravity to the whole thing for Gareth. But other than that, Gareth isn’t laughing. Gareth is a little amused by Rick saying that he’s going to kill him. that they came in, laughed, and took the place over within weeks and they did horrible things and left. “I don’t think Gareth thinks he’s the same as the ‘large man’ or the people that came in.

Galaxy on fire 2 youtube5/16/2023 Not only does this customisation guarantee depth, but it prompts an investment into Galaxy on Fire 2 beyond the battlefield. As a result, you're nudged into taking side quests in order to accumulate money for decking out your ride. Reasonable pricing ensures that you can afford what you need in order to progress, but you never seem to have enough to buy that advanced shielding or big nuclear weapon you have your eye on. Galaxy on Fire 2 nails customisation, with dozens upon dozens of different weapons, parts, and even entire ships. There are incentives for pursuing side quests and non-essential activities like mining and playing the market: cash rewards can be spent on outfitting your ships. Playing a dynamic economy based on regional supply and demand offers a sophisticated means of making a buck. These space lounges also enable you to buy black market goods that aren't available in official shops, or at least for less than you'd pay through proper channels. Whether it's mining for exotic metals in an asteroid belt or seizing pirated goods using a tractor beam, these missions are entertaining and varied enough to keep you coming back. Within each planetary system is a space station complete with a space lounge where crazy cocktails and side quests are served.Īt any time, you're welcome to pop down to the intergalactic pub and acquire optional objectives for extra cash. While the story is always moving forward, there are enough compelling side quests and optional activities to distract you. Originality is part of the appeal, but the well-written scenarios and dialogue play a greater role in its success. Maxwell is immediately engaging and grows more so as the story develops. In a Galaxy on Fire far, far awayĪ gripping story draws you in from the start. Plenty of minor criticisms can be heaped on it, but in the grand scheme of things Galaxy on Fire 2 is an adventure that goes beyond where any iPhone and iPod touch game has gone before. Its gameplay burns slow and steady relative to instantly gratifying quick-fire space shooters, though the economic wheeling and dealing that cools its action also provides enormous depth. Shining brightest in a constellation populated by dim games like Warpgate, it offers a point of reference from which the genre can chart a course forward. When the projectiles are close to any ship, asteroid, or space junk, they will detonate in small explosions.In the cold dark space of intergalactic action games, Galaxy on Fire 2 is the North Star. Scatter guns have slow loading speeds, but their projectiles are very fast and have great range. They will fire everywhere if not locked on a target. Also, when the scanner is locked onto a target, the projectiles will aim towards it, making them good fire-and-forget weapons. Thermal Fusion weapons are slightly slower, but deal more damage per projectile than auto-cannons. Their recoil can cause a bit of projectile spread. However, these are notorious for their poor range.ĮMP blasters do not damage shields or armor, and therefore cannot destroy a ship, but deal EMP damage to disable a ship momentarily, this allows for any 'loot' to be taken without having to destroy the ship.Īuto-cannons are similar to today's machine guns, with high rates of fire but low projectile damage. Pulsed lasers deal average damage and have average loading speeds compared to similar-priced weapons, while M6 series of continuous beam lasers deal high, concentrated damage at the cost of slow loading speeds like a sniper.īlasters have higher loading speeds, and thus have higher damage output compared to pulsed lasers. There are two types of lasers: pulsed and continuous beam. K indicates weapons that can only be purchased at the Kaamo Club.) Some of these weapons can be purchased at the Kaamo Club Lounge even without the DLC. ( V indicates a weapon introduced in the Valkyrie DLC, while S indicates a weapon introduced in the Supernova DLC. The following is a listing of all the weapons in Galaxy on Fire 2: In most cases, the more expensive the ship, the more primary weapons it can hold. The amount of primary weapons a ship can mount is often a starting point for determining how it will perform in the battlefield, ranging from zero ( Cormorant, Rhino) to four ( Ward, Aegir, Nemesis, Bloodstar, ect), and five if you own the Groza Mk II. Fortunately, all of the primary weapons have infinite ammunition so a pilot does not have to worry about it in the middle of an intense firefight. In Galaxy on Fire 2, the large button on the right-hand side of the screen usually fires primary weapons, and when double tapped, leaves them on autofire. Primary weapons, really, are the first things on hand to be fired, and are used often as a result. Dpo7254 signal path compensation error5/16/2023 CL open-circuited.īy equating the pole in Case 1 to the zero in Case 2, and the pole in Case 2 to the zero in Case 1, we derive the following two equations: With C L open, the pole and zero are a function of C f. With C f shorted, R x << R f, and R o << R in, the pole and zero are functions of C L, R o, and R x. With this in mind, and referring to the circuit in Figure 4, let’s apply this principle to one capacitor at a time. Think of the capacitors, C f and C L, as open circuits at dc, and shorts at high frequencies. VB is connected to the amplifier’s minus input. To better understand this technique, consider the redrawn feedback portion of the circuit shown in Figure 4. A small series resistor, R x, is used to decouple the amplifier output from C L and a small capacitor, C f, inserted in the feedback loop, provides a high frequency bypass around C L. In-the-loop compensation circuit.įigure 3 shows a commonly used compensation technique, often dubbed in-the-loop compensation. For example, here’s a compensation technique that has the added benefit of filtering the op amp’s noise via an RC feedback circuit. Q: So, different circuits call for different techniques?Ī: Yes, absolutely! You’ll choose the compensation technique that best suits your design. A simple op amp circuit with capacitive load. This note discusses typical questions about the effects of capacitive loads on the performance of some amplifier circuits, and suggests techniques to solve the instability problems they raise. The –20 dB/decade slope and 90° lag contributed by the pole, added to the –20 dB slope and 90° contributed by the amplifier (plus any other existing lags), results in an increase in the rate of closure (ROC) to a value of at least 40 dB per decade, which, in turn, causes instability. The loaded gain can be expressed as follows:Īnd A is the unloaded open-loop gain of the amplifier. Typical applications include sample-and-hold amplifiers, peak detectors, and driving unterminated coaxial cables.Ĭapacitive loading, as shown in Figures 1 and 2, affects the open-loop gain in the same way, regardless of whether the active input is at the noninverting or the inverting terminal: the load capacitance, C L, forms a pole with the open-loop output resistance, R O. To avoid sacrificing performance with light loads, most amplifiers are not heavily compensated internally for substantial capacitive loads, so external compensation techniques must be used to optimize those applications in which a large capacitive load at the output of the op amp must be handled. Ideally, an otherwise stable op amp with R O = 0 will drive any capacitive load without phase degradation. attenuation and phase shift of the feedback circuit, including the effects of output loads, input impedances, and stray capacitances.Īmong the parameters cited above, the amplifier output impedance, represented by the output resistance, R O, is the one factor that most affects performance with capacitive loads.the amplifier’s internal architecture (for example, output impedance, gain and phase margin, internal compensation circuitry).The ability of an op amp to drive capacitive loads is affected by several factors: The problem is especially severe when large capacitive loads, such as LCD panels or poorly terminated coaxial cables, must be driven-but unpleasant surprises in precision low-frequency and dc applications can result as well.Īs will be seen, the op amp is most prone to instability when it is configured as a unity-gain follower, either because (a) there is no attenuation in the loop, or (b) large common-mode swings, though not substantially affecting accuracy of the signal gain, can modulate the loop gain into unstable regions. Although some capacitive loading is inevitable, amplifiers are often subjected to sufficient capacitive loading to cause overshoots, ringing, and even oscillation. But, I need a refresher-NOW.Ĭapacitive loads often give rise to problems, in part because they can reduce the output bandwidth and slew rate, but mainly because the phase lag they produce in the op amp’s feedback loop can cause instability. Q: ADI has published a lot of information on dealing with capacitive loading and other stability issues in books, such as the amplifier seminar series, in earlier issues of Analog Dialogue, and in some design tools. Ask The Application Engineer-32: Practical Techniques to Avoid Instability Due to Capacitive Loading Food poducer5/16/2023 If the Exo team can get Americans past that, the idea of the protein bar may be about to change in a big way. While 80 percent of the world’s population is said to eat insects regularly, in the Western world it’s seen more as a strange delicacy. Lewis and Sewitz admit that getting people to consider insects as a food source is a challenge. Plus for every hundred pounds of feed, you get 60 pounds of cricket protein - 12 times the average yield from cattle. Crickets produce one hundred times less greenhouse gas than cows, and require 0.05 percent (that’s five one hundredths of a percent) of the water cows do. It also contains all essential amino acids, and twice the iron content of a comparable serving of spinach.īut perhaps the best reason to start eating crickets is its environmental benefit. That’s more than twice the protein content of other commonly lauded healthy protein sources like beef jerky, chicken, and salmon. Why cricket flour? Well, even with just 40 crickets per pound, you get flour that consists of 65 percent protein. With 2,000 crickets – yes, crickets – a recipe for cricket flour, an oven, and a blender, Lewis and co-founder Greg Sewitz created a protein bar that makes insects palatable.
