Is the pressure washer wheel-based, handheld or wall-mounted? “One thing I look for in a pressure washer, aside from cleaning power, is portability,” says Todd Saunders, CEO of FlooringStores. “Higher PSI and GPM ratings are suitable for tougher cleaning jobs.” Portability “Different pressure washers offer varying levels of pressure, typically measured in PSI (pounds per square inch) and GPM (gallons per minute),” says Aaditya Bhatta, a landscaping expert and founder of Plantscraze. “They’ll also deliver the most water to the work.” That extra power is why Bryan Clayton, the CEO of the lawn and landscaping service GreenPal, suggests that people who need to do heavy-duty pressure washing “always opt for a gas-powered model, ideally with 8 hp or above.” Pressure Level “Gas will deliver more power and is more suitable for commercial and professional users,” Clement says. They’re also quieter, lighter and better for the environment.īattery-powered pressure washers have similar benefits, plus they’re portable. “Electric units are compact, powerful enough for most jobs around the house, and they store easily,” he says. Mark Clement, a contractor, tool expert and founder of MyFixitUpLife, uses an electric pressure washer. You’ll need to choose between gas-powered, electric-powered and battery-powered. Here are the main factors to take into account when selecting the best pressure washer.

It’s a versatile tool that saves a lot of time and effort compared to scrubbing or using a garden hose.”īut while watching others pressure wash their stuff may be a stress-reducing activity, buying your own pressure washer - from among the many brands and models available - can be a little more fraught. And a pressure washer can be used to prep surfaces for paint or stain. ![]() “It’s an absolute godsend for removing stubborn dirt, grime, and mold that often accumulate on patios, driveways, decks and fencing. “As a landscaper, I find a pressure washer essential for keeping outdoor spaces clean and well-maintained,” says Lindsey Hyland, a gardening and landscaping expert at Urban Organic Yield. It may even inspire you to buy your own pressure washer, even if it’s simply a hack to turn your garden hose into a pressure washer.

The Bergen Mall was the target of a lawsuit by nuclear-freeze advocates who challenged the malls restrictions on distribution of literature to shoppers. While different conclusions have been reached elsewhere, New Jersey's approach has been one of the most expansive in providing groups with access to malls as a public forum, despite their private ownership. This issue has become particularly relevant in New Jersey, where malls in both suburban and exurban areas have largely supplanted local downtown districts as shopping destinations, depriving individuals and organizations of a public location to reach out to neighbors for distribution of fliers and other forms of expression. ![]() With the shift in shopping from publicly owned Main Streets to privately held shopping malls, the question of access to malls, and their shoppers, as a public forum has been an issue raised nationwide. Role as public square Freehold Raceway Mall in Freehold This came one day after the Jersey Gardens closed after an employee tested positive for COVID-19 and Jersey City Mayor Steve Fulop closed Jersey City's two major shopping malls Newport Centre and Hudson Mall. ĭespite an early refusal to temporarily close other New Jersey shopping malls during the COVID-19 pandemic, New Jersey Governor Phil Murphy eventually agreed to do so on March 17, 2020. The popularity of the mall as a destination is often cited as one of the factors that led the mall's host municipality to change its name from Delaware Township, to its current name of Cherry Hill Township. (The Southdale Shopping Center in Edina, Minnesota, was the very first enclosed mall, beating Cherry Hill to the honor by five years). Ĭherry Hill Mall, was the first large indoor shopping center on the East Coast of the United States and attracted busloads of visitors soon after its opening in October 1961. Earl Puckett confidently announced The Bergen Mall as the largest of ten proposed centers, stating that there were 25 cities that could support such centers and that no more than 50 malls of this type would ever be built nationwide. The Bergen Mall, which was fully enclosed in 1973, was first planned in 1955 by Allied Stores to have 100 stores and 8,600 parking spaces in a 1.5 million square feet (140 × 10 ^ 3 m 2) mall that would include a 300,000 sq ft (28,000 m 2) Stern's store and two other 150,000 sq ft (14,000 m 2) department stores as part of the initial design. The Garden State's second mall-type shopping venue, Bergen Mall (now known as Outlets at Bergen Town Center), was built in Paramus and Maywood and was officially dedicated on November 14, 1957, with great fanfare, as Dave Garroway, host of The Today Show served as master of ceremonies. The shopping complex is now known as Westfield Garden State Plaza. It opened in three stages between May 1957 and September 1960 and was fully enclosed in 1984. Garden State Plaza was the state's first shopping mall. This high level of retail sales persists despite the fact that the County, in general, and the Borough, in particular, have blue laws that force the malls and other retailers to close on Sunday. Paramus, in Bergen County, is one of the largest shopping meccas in the country, with its four major shopping malls accounting for a significant proportion of the over $5 billion in annual retail sales generated in the borough, more than any other ZIP Code in the United States. New Jersey, the most densely populated state in the United States, and in the suburban sphere of influence of both New York City and Philadelphia, Pennsylvania, has a comparatively large number of notable malls throughout the state. ![]() History Westfield Garden State Plaza in Paramus Shopping malls in New Jersey have played a major role in shaping the suburban landscape of the state following World War II. ![]() ![]() ![]() However, this will result in the Warper relentlessly hunting down their prey, often being evasive and becoming more streamlined the closer it gets.

It travels in seemingly random directions, seeking out creatures infected with the Kharaa Bacterium. When close to a Warper, it emits loud electronic frequencies, bearing a resemblance to white noise. The Warper can be drawn from its path by infected fauna, which it will pursue and attempt to kill, or by the approach of the player, who, depending on how contaminated the player is it will either attack or merely observe. The Warper patrols a small area around its spawn point, warping out once it reaches the end and then reappearing at the beginning. While patrolling, it moves in slow arcing trajectories, propelled by its tentacles with its upper body perfectly still, before changing course with a sudden jerk. ![]() The Warper's lower section consists of six tentacles, of which only the two translucent blue limbs are used for propulsion, while the rest serve as the end tips of its main body's cloak.

Its body is mostly covered with a thick, purple, cloak-like skin overlaying its translucent pale blue body. It has four small eyes that give out a distinct magenta bioluminescent glow. It sports a circular mouth consisting of a pair of mandibles to either side and two large, blunt teeth in the center.

MATLAB Programming Tips (Programming and Data Types) Programming and Data Types ![]() ![]() Generally, 7g of gelatine will set 500ml liquid 7g of powdered gelatine is around 2½ teaspoons. If you have a set of those very precise scales that coffee buffs seem to use these days when making the "perfect espresso”, that can help. As to how much powdered gelatine is the equivalent to leaf gelatine - there is no simple answer as there are several quite differing varieties on the market. The reason I’m pointing this out is that a fruit jelly made from fruit juice, or a panna cotta or bavaroise made from cream and milk, can vary enormously in how much gelatine is needed, with skim/trim milk needing more to set it than regular milk. ![]() With fruit juice, apple juice generally is very watery and is mostly water whereas tomato juice is much thicker, and like cream, has less water so needs less gelatine. ![]() Milk and cream (think panna cotta) are milk fats suspended in water - cream having more fat, and therefore less water - so it needs less gelatine to set it. There’s no solids or fats in water - just a few miniscule amounts of harmless chemicals like sodium, magnesium etc. For me the easiest way of describing this, which will affect how much gelatine you need for a recipe, is that water is 100 per cent pure liquid. The scientific part of what constitutes “liquid” is also worth pointing out. Writing cookbooks and knowing people around the world are feeling disappointed with the end result is also heartbreaking, as all my recipes work when made at home, which is where I always shoot them. Some will set a liquid much firmer than others, some will produce a more cloudy result than others, some need more soaking - or blooming, the term more often used for soaking gelatine. The more I looked into it the more complicated it became as not all gelatines are alike. They were thinner and smaller - which obviously meant one sheet was going to set much less liquid than mine. Well it turned out that the leaf gelatine he’d bought from the supermarket was quite different to the one we chefs were using in restaurant kitchens. Then one day I was talking to a friend, a keen home cook, and he said the panna cotta recipe I’d given him was too soft and he’d had to serve them in the mould rather than unmoulding. As to how many teaspoons set 100ml of liquid - I could never really figure it out. For years it was a very simple equation of one sheet to set 100ml liquid. Then on the scene appeared the miracle answer - sheets that you simply soaked in ice cold water for five minutes, before gently squeezing out the excess liquid and adding to a warmed liquid to dissolve them. It wasn’t in reality a huge problem but it caused me a few moments anguish from time to time. ![]() Dissolving powdered gelatine had always been slightly tricky as I could never seem to get 100 per cent of the granules into the liquid I was trying to set - there would always be a few slightly undissolved ones stuck to the dish I’d soaked them in. When I first began using sheet, or leaf, gelatine in the late 80s I felt one of the culinary world’s hassles was forever answered. Is it true that the sheets are superior to the powder? I avoid making anything using gelatine as I think I am going to muck it up by buying/using the wrong thing. I am very confused about gelatine - many recipes use the sheet variety now but seem very loose on the amount, one sheet seems to do it all, whereas the powdered variety is measured out carefully.

So my assumption is that the computer is designed to survive that heat for a short period of time. The computer's SMC firmware is designed to cause the computer to shutdown when the limit is reached to protect the processor and computer. You would need to obtain the Intel specifications for the particular processor in the computer to find out what it is. The thermal cutoff of the CPU is somewhere in the neighborhood of 100-125º C. How long any of them last is just a statistical probability. So your computer may run without incident at those high temperatures while mine may quickly fail. But since every instance of any model is unique some may last longer than others under the same heat stress.

Short response to mkcustard: Yes, and two months is a crazy unacceptably long time, IMO.I have a 2020 Bolt that I purchased in March. Yay! And it was all covered under warranty except for the very expensive replacement 12V battery. But the good news, and I'm really reluctant to say this lest I jinx myself, is that the car has performed flawlessly since then. No loaner was offered, but I didn't really need one so I didn't ask. ![]() I took the car in on 11/13/21 and got if back 12/18/21 - 5 weeks. Apparently the BCM is under the car with the drive battery, not readily accessible and also some special tool is needed, which your local dealer probably doesn't have on hand. It took a week and a half before the car was ready. Then I thought ok, a quick component replacement and off we go, but no. They checked it out and then had to wait for clearance from GM (!?!) before ordering a replacement battery control module. Then I was really stuck, no 12V battery, no drive battery, and jumping didn't work. I need a new BCM, not just the latest software, right? And good luck getting one, apparently.Ĭlick to expand.Short response to mkcustard: Yes, and two months is a crazy unacceptably long time, IMO.įollowing up on my post of, I finally "killed" my car by also letting the 12V battery run down. Each time, they have loaded the latest Battery Control Module software and then the car works better - even fine - for a week or two or three, then the problem recurs. (How can that be? IMO that's a big problem right there.) We all know troubleshooting an intermittent problem is difficult. Amazingly, even though the check engine light has been on for days, there are no diagnostic code in the system. When I take it to the dealer, they cannot reproduce the problem. If you plug in the charging cord, the display says "Not able to charge". Meanwhile, the check engine light is on all the time. The way out is to leave the car on (as if you have a choice) until the gas engine comes on, drive for a little bit, then shut the car off and back on. If I push the button to turn the car off, it doesn't turn off, it reinitializes. When I put it into gear, it says "Action required, shift into park". I think this will sound familiar: I turn the car on, but it doesn't "see" the battery, and shows 1 EV mile. I have a 2017 Volt with 45k miles that I've taken to the dealer maybe 4 times over the past few months. But I was able to continue on by adjusting the idle speed higher on the carb so I could accelerate slowly, shifting through the 4 gears. Our current Subaru Outback has been excellent. I didn't so much like the Chevy Venture, Mercury Villager & '71 Volkswagen Beetle. But I also liked my two Accords, Saturn, Mazda 626, Chevy Nova & Dodge Colt. But my 40 years of driving experience suggests that's not how it works. But I was prepared for that to lose capacity over time. Because shouldn't electrical components have far more life than their mechanical counterparts? I understand there needs to be an exception for the battery. I felt I was on the road to many trouble-free miles. That's not right for a 2 1/2 year-old car. My wife loves driving the Volt, but I don't want to put her in that situation. It isn't so much the time in the shop, but the frequency and the fact that both times it died on me, the car would only run again after I fiddled with it for 10 minutes or so. ![]() ![]() ![]() I don’t know what that means, but it might be part of the problem. The DMV’s deputy director, Anita Gore, says the test is periodically evaluated and altered using a “linear-on-the-fly testing algorithm.” “Again, what does that prove about my ability to safely operate a motor vehicle?” “I missed a question about oil tankers and railroad crossings,” said Arthur Siciliano, 87, of West Hills. The animal question had a lot of readers barking. One example: What is the fine for abandoning an animal by the side of the road? Say what? I don’t know any senior who would do anything so stupid and heartless.” “Some of the questions were incredibly picky,” Bryant said, “and unrelated to anything important for senior drivers to remember. She flunked the test on her first try and passed on the second, but said none of the 25 questions had been on the practice exams. She said she’s been driving for 57 years, spent a Saturday studying the driver handbook, took five practice exams on a Sunday and thought she was ready. Now let me get back to test questions that irked so many readers, including Carolyn Bryant of Brea. But you’ll still have to go to a DMV office for the eye exam. You can find out whether those are options for you by going to the Senior Drivers website and beginning your license renewal process online. I was told that in some instances, depending on driving records and other factors, you might be able to take the test online or qualify for something called the e-learning course, which is a roughly 45-minute driver’s ed and testing program. But a few readers told me they had been able to take the test online at home, so I asked the DMV what was up. When I wrote that at age 70 and older, renewing your license requires an in-person eye exam and knowledge test, that was mostly true. I’m going to get to both of those topics, but first some clarifications. And a lot of people said it would be more useful, past a certain age, to require driving, rather than written, tests. ![]() A lot of people complained about the test questions. Two things stood out for me as I perused reader comments. But that’s somewhat misleading because they tend to drive fewer miles. I dug up statistics suggesting that older drivers, by percentage, have fewer accidents than those in their 20s and 30s. Many people argued that you should be judged on your driving record, not your age. My column explored the question of whether, as some insisted, this was a case of age discrimination. ![]() The requirement had actually been in place since 1978, but was temporarily lifted during the COVID-19 pandemic, making it possible to renew online with no hassles. 1 - that anyone 70 or older who wants to renew has to go to a DMV office for a knowledge test and an eye exam. I’d written about the requirement - as of Jan. They have opinions, suggestions and gripes they can’t wait to unload, and I’m still going through hundreds of responses to my column about driver’s license renewals for people 70 and older. Make it as entertaining as possible, write it down, go back to that note every now and then.When it comes to the California Department of Motor Vehicles and its policies and practices, people are not timid. If you plan on pursuing schooling after high school, I definitely recommend putting great amounts of effort into note taking and learning techniques that work for you.įor this, whenever you read over something that seems confusing, or that you just kinda read over without it sticking, go back and think of a scenario where the rule will be applicable. What I did in school in general when I had to memorize or learn something was make a good, interesting powerpoint. In FL, the test bank is ~500 questions, of which you will get 50. I'm not too certain about the specifics of the written test, especially for CA, but I know for most state testing, any sort of official practice tests are prohibited from having the exact same questions as any of the real test. You can also look up videos that summarize the DL handbook, however YMMV with that. I suggest making notes, a powerpoint, or a video or pretty much anything to get more than one part of your brain active at once while studying, so that it sticks. You'll want to read through/study 26-108. ![]() ![]() ![]() You can also use the hyphen to match numbers. Match Numbers and Letters of the Alphabet For example you can match all letters between a and e with "".Ī regex like "at" would match all strings that have in order one letter between a and e, then an a and then a t, such as " cat", " bat" and " eat", but also "bird bath", "bu catini", " date", and so on. To avoid all that typing, you can define a range. You have seen above how you can match a group of characters with character classes, but if you want to match a long list of letters that is a lot of typing. You can use a character class (or character set) to match a group of characters, for example "bg" would match any string that contains a b, then one letter between a, i and u, and then a g, such as " bug", " big", " bag", but also "cab bage", "am bigous", "lady bug", and so on. ![]() Match Single Character with Multiple Possibilities matches any character, for example "hu." would match anything that contains an h followed by an u followed by any character, such as " hug", " hum", " hub", " huh", but also " husband", "c hurros", "t humb", "s huttle" and so on. For example "yes|no|maybe" would match any string that contains one of the three sequence of characters, such as " maybe I will do it", " maybelline", "mo nologue", " yes, I will do it", " no, I don't like it", and so on. Match a Literal String with Different PossibilitiesĪ regular expression can be used to match different possibilities using the character |. The easiest way to use RegEx it's to use it to match an exact sequence of characters.įor example the regex "Kevin" will match all strings that contains those letters in that exact sequence, as " Kevin", " Kevin is great", "this is my friend Kevin" and so on. Still, it gives you a good overview of basic RegEx features, so let's follow this curriculum so you can get a good idea of what RegEx can do. Keep in mind that the freeCodeCamp curriculum presents RegEx for JavaScript, so there is not a perfect match, and we need to convert the syntax. To see a good variety, let's use some of the examples presented in the RegEx freeCodeCamp Curriculum. You can do a lot of different things with RegEx patterns. RegEx lets you match patterns by character class (like all letters, or just vowels, or all digits), between alternatives, and other really flexible options. You can use RegEx in many languages like PHP, Python, and also SQL. ![]() RegEx on its own is a powerful tool that allows for flexible pattern recognition. What about if you need more complex pattern matching? Well, for that you need to use Regular Expressions. WHERE name NOT SIMILAR TO "%u%" RegEx in SQL This is how you would write the example we used before using SIMILAR TO instead: SELECT name FROM planets You can use this operator with NOT in front to have the opposite effect. Let's take the example used with LIKE and let's use it here too. You can use the % operator for any number of characters, and the _ operator for exactly one character. The SIMILAR TO operator works in a pretty similar way to the LIKE operator, including which metacharacters are available. ![]() You can use it in addition to or in place of LIKE. nameĭepending on the SQL flavour you are using, you might also be able to use the SIMILAR TO operator. With this query you get all planets whose names don't contain the letter u, like below. The NOT LIKE operator finds all strings that do not match the pattern. With this query you would get the below names of the planets that end with "us". Where planets is a table with the data of the solar system's planets. ² (in the example, third and fourth characters are determined) Example query SELECT name FROM planets ¹ (in the example, second to last and third to last characters are determined) Strings that have a specific substring at a specific position from the beginning² Strings that have a specific substring at a specific position from the end¹ Strings that have a specific substring anywhere in the string Strings that end with a specific substring Strings that begin with a specific substring You can use these characters in a wide variety of use-cases. The operators are used like this: column_name LIKE pattern. SQL patterns use the LIKE and NOT LIKE operators and the metacharacters (characters that stand for something other than themselves) % and _. They have a more limited syntax than RegEx, but they're more universal through the various SQL versions. SQL patterns are useful for pattern matching, instead of using literal comparisons. In this article, we'll look at how you can use the Contains String query. Being able to do complex queries can be really useful in SQL. ![]() |
