Who would have believed that six weeks in, they're the only unbeaten team left? And that young quarterback (Kyler Murray) can do so many amazing things."

TECHNOLOGY IS A KEY on the current tour, according to Jardine. Performance An occasional whiff of diesel fuel and engine rattle are small prices to pay for the economy and durability of a modern diesel engine.Īlthough the 1.9-liter four-cylinder engine produces just 100 horsepower, it also churns up 177 pound-feet of torque starting at a low 1,800 rpm. The test car was a GLS, the fancier of two versions over the base GL. What it is Volkswagen keeps the faith with its thoroughly modern diesel, found here in a nicely trimmed compact four-door hatchback. Not the least of which is getting 40-plus miles per gallon. ![]() Here, diesel is about the same price as a gallon of gas, but there still are advantages. The new diesels use turbochargers and direct fuel injection (thus the TDI label) that give them decent performance while cleaning up the smell and smoke.ĭiesel is the thing in Europe where gasoline is wildly expensive and diesel significantly less so. But they also were slow, noisy, smelly and left a hanging trail of black smoke everywhere they went. VW diesels made their appearance, giving hip conservationists an opportunity to drive a groovy Rabbit powered by a durable and fuel-saving diesel. General Motors tried its hand at diesel V-8 engines, with less-than-stellar results. Mercedes-Benz was a long-standing proponent of diesel, so that was a good way for the wealthy to conserve. One of the less-absurd alternatives was diesel, already in wide use by overland tractor-trailers and other heavy-duty trucks. So everyone started looking at ways to conserve fuel, including absurd electric minicars that looked like phone booths and sundry gas-saving devices that you could hook up to the family sedan. Of course, we blamed OPEC, the cartel of oil-producing countries. With that in mind, I’ll concentrate this review on the car that will appeal to most people, not to mention still being available.įor those of us at a certain age, VW diesels evoke the gas crisis of the 1970s, the first time we faced widespread fuel shortages and soaring prices. ![]() The R32 made just a brief appearance as a 2004 model, and despite the significant price tag, has pretty much sold out. This turned out to be a sweetly enjoyable car that was fun to drive and achieved outstanding fuel mileage.Īs much as the R32 was about fantasy, the TDI was about the real world. But don’t turn up your nose so fast at diesel. The other VW hit a little closer to home, a four-door TDI turbo-diesel with automatic transmission at $10,000 less. The unassuming VW compact was transformed by the performance treatment and turned heads with both its shocking acceleration and its equally shocking price tag: $30,000. The first was a roaring R32, a limited-edition pocket rocket with 240-horsepower, all-wheel drive, rock-hard suspension and a cocky attitude. ![]() Two Volkswagen Golfs have passed under my hands recently, and they were as different from each other as they could be. ![]() Manage your healthcare and connect with your provider with FollowMyHealth Portal.

Thank you for trusting The Iowa Clinic with your medical care. Therefore, at optical scan resolutions higher than that, I would expect multiscanning to cause blur from movement between samples, when viewed at the pixel level before downsampling. I suspect it is the mechanicals of the Epson that limit it to an effective maximum resolution of about 2000-2400 spi. The greater the resolution, the harder this is to do. The mechanicals have to be precise enough so that all samples are precisely aligned with each other. On consumer flatbeds such as an Epson, the CCD is squirming around between the samples, and you get blur just as you would if you thumped your camera between multiple exposures. The problem with multiscanning is mostly mechanical. Determining what is random color variation caused by noise and what is information requires a fine touch, of course. Noise removal software, on the other hand, looks for random color variations at the pixel level after the image is already scanned, and attempts to smooth those by averaging them with their neighbors by some algorithm or other. It should never affect the detail in the scan (but see below). By sampling it several times and taking an average, that noise is, to some extent, filtered out.īut I would only expect an improvement in highlight areas of negatives or shadow areas of transparencies, where the light reaching the sensor was dim enough to be close to the sensor's noise floor. When the scanned material is thick, the signal is close to the noise floor of the CCD, and so the noise, which is always random in nature, has a greater influence on the resulting pixel. The idea behind multiscanning is that it takes several samples of the same spot. Perhaps the noise the Epson generates is so consistent/non-random Vuescan can't determine what's noise and what's not. I did notice a difference with my Minolta and previous scanner. ![]() I think this will help allot of people that struggle with grain issues.I haven't noticed any difference with my Epson scanner. Also as this article points out the noise is mostly in the darker areas - so you can recomp back or relayer back the upper mids and highlites if you want - which further minimizes your filtering. The idea is to isolate areas of detail as a mask, and smooth areas as another mask. We used to use convolve matrixes - to isolate edges, but find edges, or sobel filtering and curves does the same. ![]() I found another psd article, which shows exactly what I do (in a different way that does the same steps and results ) in my compositing package to control the degraining. You can enhance with the below to retain the detail on the edges. Maybe it works for allot of stuff though? But not this one - even color saturation is getting greatly reduced around detailed areas. I tried what you wrote and on an image I'm loosing allot of edge detail. In my experience Dt will accept an image a little bit softer over having some grain. Not every image should be pristine, sterile or glassy. I think if the editors sees any grain - the image is refused - which is Dt's choice - but in allot of cases some film grain makes an image look much more realistic. However since I work with film, I know how much grain there is there I am surprised that DT kicks back photos or digitally created images that has less film grain than 35 mm shot imagery. There is no magic bullet for every image if you are picky as I am. Check each color channel too - as you might treat just a channel individually as others maybe fine. Those pink blocks you got to recolor away. Sometimes retinting the colors to eliminate the color artifacts ffrom jpegging. I tend to try different stuff for different areas of the image. I spend the most time on older jpeg shot images - and those take time. and also Digital Fusion's built in degrainer and I composite or blend back so i'm only degraining the areas i want. You still need light though.įor egregious grain, I have been using a psd/ after effects plugin called remove grain. Canon seems to be the best bet in my opinion for allowing you to push your iso without much sacrifice to noise. If you shoot everything in raw, and not go too high on the iso you will be happy there. You'll find through the tabs there is color and luma grain reduction - and this works exceptional without loss of detail. However I really like the canon raw photoshop importer. I have several tools for this and have used them with photography as well. ![]() I come from a visual effects background - where we are adding film grain to our images to look like film.īut we also degrain film footage that is exceptionally noise - or degrain so we can work on it and then regrain in the composite. Im going to try that LAb color technique and see what it does. ![]() This group is not included in the total reported by groupCount. ![]() There is also a special group, group 0, which always represents the entire expression. ![]() The groupCount method returns an int showing the number of capturing groups present in the matcher's pattern. To find out how many groups are present in the expression, call the groupCount method on a matcher object. In the expression ((A)(B(C))), for example, there are four such groups − For example, the regular expression (dog) creates a single group containing the letters "d", "o", and "g".Ĭapturing groups are numbered by counting their opening parentheses from the left to the right. They are created by placing the characters to be grouped inside a set of parentheses. PatternSynta圎xception − A PatternSynta圎xception object is an unchecked exception that indicates a syntax error in a regular expression pattern.Ĭapturing groups are a way to treat multiple characters as a single unit. You obtain a Matcher object by invoking the matcher() method on a Pattern object. That means when you use a pattern matching function with a bare string, its equivalent. Like the Pattern class, Matcher defines no public constructors. Regular expressions are the default pattern engine in stringr. Latest News is a community devoted to the topic of regular expressions. Matcher Class − A Matcher object is the engine that interprets the pattern and performs match operations against an input string. Regex Tester Allows you to test while you write your Regular Expression Shows all matches found in the PropertyGrid control so that you can drill down into the groups and captures Shows the group name too, if you set one View all Regular Expression resources. These methods accept a regular expression as the first argument. To create a pattern, you must first invoke one of its public static compile() methods, which will then return a Pattern object. The Pattern class provides no public constructors. Pattern Class − A Pattern object is a compiled representation of a regular expression. The package primarily consists of the following three classes − They can be used to search, edit, or manipulate text and data.

Place the RAND() functions into cells F100:F107 to obscure the spreadsheet’s workings. Here’s how to combine the functions into a spreadsheet. Now all we need is a CONCATENATE() function in cell A110 to assemble the password from those eight cells. If you simply fill the IF, CHAR*(), and RAND() statements down seven rows, you’ll get a matrix of cells in the range A100:A107 that will form your password. In cell A100, we place a CHAR() function with the cell address of our IF statement in the parentheses:Ĭell A100 will now contain a number from zero to nine, a lowercase letter, or an uppercase letter. Now that our IF statement in cell E100 returns a number from one of these three ranges, it’s time to use that value to generate an ASCII character. The functions to generate these number ranges are, respectively: By consulting an ASCII table ( click here to download an ACSII table from CNET’s ), we know that the codes for numbers are between 48 and 57, lowercase letters are between 97 and 122, and uppercase letters are between 65 and 90. Next up are a trio of RAND() functions to generate the ASCII values of numbers and letters. With the RAND statement in cell F100, the function in cell E100 looks like this: ![]() If it’s greater than five, we’ll use another IF function to see if we’ll use an uppercase (6-10) letter by referring to the value in cell G100 or a lowercase (11-15) letter by using the value in cell H100. Next, I used nested IF functions to provide three possibilities: If the number is between one and five, we’ll refer to cell I100, where we’ll generate the value for a numeric character. To begin, I want to generate a number between one and 15 using this code: For this spreadsheet, I wanted an equal chance of generating an uppercase letter, a lowercase letter, and a number. However, if you multiply this number by a particular value, you can generate a number within a specified range. By itself, the function returns a decimal value between 0 and 1. The heart of the random password generator is the RAND() function. Returns the character with the ASCII number provided in the argumentĬombines the characters in eight cells into an eight-character password Test the generated number to determine the character type Generate a random number within a given range The following information about how I designed the spreadsheet should be helpful if you want to alter the design to generate passwords that are even more “random.” Here is the method I used to combine several Excel functions (see Figure A) to build the password generator. ![]() And beware, some users may want to write down their random password and keep it near their PC, a strategy that defeats the purpose. Of course, convincing your users to adopt them instead of something more easily cracked is your next task. After opening the spreadsheet, simply press the key to generate a random password that can be assigned to users.Īs you can see, Excel makes it easy to generate random passwords on the fly. Even better, the password generator lets you combine uppercase and lowercase letters with numbers to make the password even more difficult to guess.Ĭlick here to download a copy of the password generator spreadsheet. By combining a series of worksheet functions, you can generate a random, eight-character password with one keystroke. The alternative, assigning unique passwords for hundreds of users, was a daunting task.įortunately, Microsoft Excel offers a solution. He mentioned users who select their favorite sports team, a password that can be easily guessed. For others, including young and inexperienced users, security is often an afterthought.įor example, a network specialist I know recently mentioned problems he has experienced with users who choose their own passwords. See how you can use a downloadable Excel spreadsheet for creating random passwords.įor IT pros, security is an ever-present concern in the enterprise. This might be important to you if you want to remove some of those that are commonly confused, such as 0 and O, or S and 5, or I and l, etc, etc.Lock IT Down: Generate random passwords in Excel ![]() The good thing about this function in particular, is that it allows you to define the letters and symbols used in all of your random passwords. Now, I am not sure where I originally found this script, or if it is the most efficient way to generate a password in PHP, but it has served me well over the year and I have used it in a few projects. |
