Bizarro Back Issues: Batman And The Challenge Of The Consumer Crusader! (1971)
Despite every attempt I've made to stop it, there's still a discussion that crops up every now and then about Batman's methods. There are people out there, people that I will never understand, who for some reason think it would make for a better story if Batman gave all of his money to charity instead of spending it on bat-shaped airplanes and rocket cars, as though there are problems that can't be solved by owning a bat-shaped airplane.
But even though I definitely don't agree, I will concede that the Dark Knight's crimefighting methods are occasionally a little dubious. Like, say, that time that Batman investigated an attempted murder by pretending to be a ghost and then yelling at someone about a bad review in the latest issue of Consumer Reports. That one was pretty weird, even if it's hard to argue with the results.
The story in question is "Challenge of the Consumer Crusader," brought to you by the art team of Bob Brown and Dick Giordano and the supremely underrated Frank Robbins in the pages of Detective Comics #415 --- and brought to my attention by long-time reader Brad Reed, who promised psychedelic lights and a mattress testing machine used as a deathtrap, which is exactly the phrase that will make me read a comic immediately. And it lives up to the promise.
And just to give you an idea of exactly how weird it is, we open up on page one with a pair of hitmen attempting to murder their target by ambushing him and throwing him into a garbage truck:
Now, I'll admit that I've lived in a small town in the south for most of my life, so this is a legitimate question that I'm asking you: Do garbage trucks in big cities come equipped with giant spiked rolling pins that can chew up a rocking chair? I mean, I know some of them have those compactor things on there, but this is like something that would be protecting magic treasure in a lich king's lair, so I'm pretty sure that this might just be a Gotham thing. You have to think that by the early '70s, there were so many left-over deathtrap parts confiscated by the city that they'd put them to some kind of good use, right?
Anyway, the murder by garbage truck rolling pin is cut short when Batman arrives to kick the hitmen in the face, along with the reveal that he waited until they were about to throw their victim into the trash compactor even though he realized they were contract killers long before. The reason he knew? He saw their shiny expensive shoes underneath their coveralls --- and he saw them from a rooftop. The man has skills.
The thing is, Batman decides not to bring the hitmen in himself. He literally just calls the cops and tells them that Jo-Jo Weems and Tag Callum --- the latest two entries in a long line of amazing names that Robbins has given to minor characters --- are in town and that the GCPD should probably be on the lookout. He himself is far too distracted by the would-be garbage pancake that he just rescued: Tom Carson, Consumer Crusader!
Okay, first of all, Batman, your best friend is Superman, a literal flying space alien who can bench press a battleship. Is the dude who writes about faulty microwaves really going to be the celebrity meeting that gets you to let out a full-on Ric Flair "whoooo?" Really? I'm not even sure I'd want Batman doing that if he met actual Ric Flair.
Anyway, since Carson has made a career of calling out companies for their faulty products, it's not hard to figure out that he's earned himself quite an enemies list in the process. It stands to reason, then, that the most likely culprit behind the assassination attempt is the guy behind the next product on the chopping block: Ben Ames, whose nonsensical "microwave anti-pollution device" is slated for a "torture test" at Carson's company this week.
And sure enough, that's who ordered the hit. When Batman heads over to the Ames estate, he finds that the businessman is up late waiting on a phone call. Not exactly a smoking gun --- I stay up late every now and then myself --- but after Batman himself calls him from the "radio-telephone and tape recorder call-monitor" in Ames's car, Ames admits that he's he one who ordered the hit.
So! For those of you keeping track at home, that's motive, method, opportunity, two hitmen that will (probably) be arrested soon and a recorded confession. That's that, right? No other investigation needed. Put a bow on this one.
For reasons I do not quite understand, Batman decides that he needs to investigate a little more, and for reasons I will never understand, he also decides that just showing up as Batman, this grim avenger, this weird figure of the night who was specifically designed to terrify criminals, just isn't scary enough. So naturally, he decides to put on Carson's clothes, slather himself in florescent paint, and hang himself outside Ames's window. You know, like you do.
But it's a good thing he did. When confronted with a full-on haint, Ames reveals that he wasn't worried about a flawed product. Instead, he was being blackmailed by Carson with the threat of a false report.
Or was he?!
If Carson was really the man behind the blackmail, then he probably wouldn't have pointed Batman in the direction of Ames, since he'd know that it would all come out. So, in the final twist of the story, it turns out that it wasn't Carson, it was one of his "Consumer Crusaders." And, shockingly enough, it's a gal!
I feel like that's an unnecessary emphasis there, Bats.
The gal in question is one Joan Wilde, who's in charge of the lab where they test all manner of products by putting them through what is essentially a series of deathtraps that may have been too outlandish for Batman '66, and as you might expect, it makes for a pretty fantastic set piece. First, he finds himself dealing with an array of psychedelic lights --- which I assume are for testing I don't know, blacklight posters? --- but then, it gets way better.
Before long, though, Batman gets the upper hand himself, bashing a crook into a control panel and setting off a bunch of machines that the crooks very obligingly walk directly into:
But Joan herself manages to escape through a side door and into a car. And again --- Batman has a car. He has the best car. It has nuclear rockets. But instead of using that, Batman just hops into the nearest available automobile, and finds himself trapped in a "test car" that's raised up and dropped onto a target to simulate a head-on collision.
And that, friends and neighbors, is where we get what might be the most ridiculous moment of the entire story, when we find out how Batman survived. See, he didn't jump out of the car. He did a backflip inside the car.
And that's pretty much that. Oh, except that Batman also apparently decides to let Ames off the hook for hiring two hitmen to to throw a man into a garbage truck where he'll be mulched alive, because it turns out he was just a good dude who wanted to use microwaves to stop pollution. So if you were wondering how to get away with (attempted) murder in Gotham City, that's pretty much it.

TV Review: "DuckTales" Season 3, Episode 14 – "The Split Sword of Swanstantine!"
by Mike Celestino | Nov 2, 2020 11:14 AM Pacific Time
Tags: Disney XD, DuckTales, Huey Dewey and Louie, Review, TV Review, Uncle Scrooge, Webby
It's a race to hidden treasure on this week's new episode of Disney XD's DuckTales reboot, with a family adventure to the Grand Bazaar of Istanbird interrupted by two stowaways who quickly prove themselves more than welcome. "The Split Sword of Swanstantine!" is the next step in the Duck clan's quest to discover Isabella Finch's missing mysteries, and Uncle Scrooge (voiced by David Tennant) has brought his nephews Huey, Dewey, and Louie (Danny Pudi, Ben Schwartz, and Bobby Moynihan, respectively), along with their friend Webby (Kate Micucci) to this exotic locale in search of the legendary weapon.
Little do they know that not only have Webby's pals Violet (Libe Barer) and Lena (Kimiko Glenn) tagged along for the ride, but there are also a number of F.O.W.L. agents on the trail of the ancient artifact as well. The sword, it turns out, is separated into three individual parts and hidden around the city, so the six kids split up into three teams of two to seek them out while Scrooge battles the evil Black Heron (April Winchell) one-on-one.
First, Dewey and Webby must parkour their way to the roof of a scaffolded building to procure the sword's hilt, but only after being flash-bombed by Gandra Dee (Jameela Jamil). In their blinded state they learn to trust their remaining senses and each other's instincts as they hear, smell, taste, and feel their way to the top. Then, to get the crossguard, Louie and Violet venture into an underground spice club where they confront the devious John D. Rockerduck (John Hodgman) in a Raiders of the Lost Ark-style "Spice Off." The first competitor to break a sweat after consuming the searing seasonings loses, but luckily the kids have a few tricks up their sleeve.
Lastly, Huey and Lena face off against the sneaky Steelbeak (Jason Mantzoukas) as they attempt to pry the sword's blade from an ornate design in the city's pavement. Lena uses her magic to freeze time in Huey's mind, where the young duck must confront an inner demon and eventually use its rage to defeat their enemy. Then, the entire gang reunites to stand up against F.O.W.L. in the town square, where Scrooge relies on his enemy's overconfidence and his own knowledge of Swanstantine's sword to bring the conflict to a satisfying conclusion. It's a clever way to tie an entertaining and guest star-packed anthology-style episode together in the end.

There are a variety of repairs that could need to be done inside a municipal waste plant, partly because there are different types of waste plants. Everything from water fixtures to toilets to drains to any showers installed could be causing problems. Mainlines, like sewers and water lines, could be really problematic inside a waste plant.
Here at Apollo Drain & Rooter Service, we offer a variety of services so as to serve you best. We offer CIPP pipe lining, pipe bursting, CIPP cutting, trenchless repair, underground services, and sewer inspection.
We always start with an inspection, so we can figure out what's going on inside your pipes that needs to be repaired. We inspect your pipe, then clean it, then begin our repair. We decide with you what's best for your sewer, water, or mainline. No decision is made without you or your consultation. The inspection is shared with you, so you can see the same problems that we do. A plumbing technician will be there you show you where the problem is and what it means. Even if there isn't a problem, an inspection will give you a peace of mind that couldn't be found without an inspection.
Cured-in-place pipe lining can be a great place to start with leaks, damages, fractures, or other external/internal issues. Pressure caused by tree roots or other roots can cause your pipe to fracture. With cured-in-place pipe lining, we're essentially creating a "pipe within a pipe" with a liquidized epoxy resin formula that's carefully applied and cured to the inside of your pipe.
With entire replacements or repairs, trenchless is a great and much cheaper option than traditional excavational methods. Trenchless repairs take much less time and are oftentimes a lot greater in terms of outcomes.
No matter what your needs are, Apollo Drain & Rooter Service will be here for you. Call us today at (503) 239-8801 for your consultation and free quote. We offer 24-hour emergency response services and we're open on weekends!

How often should I clean my carpets in Chester, CA?
There isn't a set amount of time you need to wait between cleaning your carpets in Chester, CA but there are elements that influence how soiled they can become like where your carpets are located, who uses them on a regular basis, and the hue. If your entry way or staircases are carpeted, then these types of areas need to be cleaned every 3 months particularly if there are more than 2 people living in your house. You must also clean your carpets routinely if you have light colored carpets because stains can be seen a lot easier than on dark colored carpets. If you smoke in the house then it is a smart idea to do carpet cleaning services every 6-12 months.
Convenient Carpet Cleaning in Chester, CA is a multi purpose service that can help with an array of challenges. Getting rid of stains, dirt, chemicals, as well as other debris will keep carpets much healthier. Frequent cleaning also re-energizes your carpet and makes it feel as smooth as the day you bought it.
There is many different ways to make sure your carpeting gets cleaned. Routinely vacuuming your carpet and taking care of messes will help preserve the look of your carpet until its next professional treatment. If you want to get that pesky dirt and dust that your normal vacuum is unable to reach, professional steam cleaning and dry cleaning can help thoroughly clean your carpet.
Chemical solutions are used to dry clean your carpet and remove dirt and soil with this method. Dry cleaning is faster and also requires less work than steam cleaning. There are three primary ways that you can dry clean a carpet.
Dry foam is the application of a shampoo that is able to dry on the carpet, and then vacuumed. The elements in the shampoo attract all of the dirt and extra soil in the carpet while it dries so it can conveniently be vacuumed.
Dry chemical cleaning is done by placing the cleaning solution on the carpet and and rubbing the mixture until the toxins lift off of the carpeting and stick to the buffer. When the buffer is loaded with dirt, it is swapped out with another one and the procedure goes on until the carpet has been completely scrubbed.
Dry compound involves applying the solution onto the carpet evenly and then scrubbing it into the carpet fibers. Use a vacuum to remove the compound from the carpet after you have finished rubbing it in. All of the dirt in your carpeting will stick to the compound and be lifted away from the carpeting.
Dry cleaning carpet is a quick and efficient way to tackle carpet cleaning in Chester, California. However, the dry method may not clean as thoroughly as steam cleaning.
Steam cleaning, or hot water extraction, uses a high-pressure hot water system to thoroughly clean and vacuum carpet at the same time. This particular method penetrates deep into the carpet's fibers, guaranteeing a complete cleaning. For people who have colleagues or family members in other regions for instance Parkton, NC carpet cleaning, make sure they know that we provide solutions all over the United States.
There are two primary ways to steam clean your carpet.
Portable extraction methods are powered by a property's energy source and uses plain tap water to clean the carpet. They are easier than other products to move from place to place and can be set up within minutes.
Truck mounted units are large devices attached to trucks or vans. The water is heated to a greater temperature than portable units, along with using a greater pressure for an even deeper clean. The only thing to take into account is that these devices need to have a long hose hooked up in order to reach indoors and clean your carpet from the truck.
Steam cleaning is the most recommended method of professional carpet cleaning, due to its ability to reach to the very depths of carpets, for a complete extraction of grime, debris, and other contaminants. Repeated professional carpet cleaning will help keep your carpets looking great and protect against unsightly stains.
With their incredible customer satisfaction, Convenient Carpet Cleaning in Chester, can help you with whatever carpet cleaning technique you pick.

Software Development, The Older The Better
Refer to this url
Statistics are taken from a perspective of 'Stackoverflow'
No of developers and their reputation, by age
Questions and answers by age
Upvotes per post, by age
The biggest problem with software development is that there is no clear career path. In fact there is one which usually looks like this.
Programmer, software engineer, senior software engineer, software manager,architect or project manager.
or Programmer, system analyst, business analyst, project manager.
These are the corporate ladder ideals which most people couldn't survive and I think one of the biggest reason is that at which ever paths taken, you are still going to require to do coding and thus if you give up on coding, the path will be broken.
However, there is such thing as career software engineer.
The first type is where you developed a software and then you are able to create an industry or revolution out of it. Good examples are..
Bill Gates - Microsoft founder who developed MS Dos.
Google's founders - who developed search engine for Google.
David Filo (Yahoo's founder) - who developed Filo Server Program (web programming language)
Mark Zuckerberg (Facebook's founder ) - who developed Facebook.
The success enable is everything such as achievements, revolution, business and wealth.
The second type is where you do everything in a single job (programming, software engineering, analysis, architectural and project management). Such usually happens to those where they engage with one project with one company, completed the project and then go to another project with another company, bringing over the experience. Good examples of this are ...
Lars Rasmussen who developed a software which eventually become Google Maps today.
Ray Ozzie who developed Lotus Notes which eventually acquired by IBM.
Jeff Robbin who developed a music player which eventually become Apple's iTunes.
The success enable is that such people made money when the bigger company acquired the smaller company.
The third type of career software engineer is when someone created a software, make it open source or free and becomes advocate for it. Good examples are..
Linus Torvalds who initiated the Linux kernel.
James Gosling who developed Java programming language.
Bram Cohen who developed Bit Torrent.
The success enable is that they become popular and somehow able to make a lot of money from consultancy works for various industries.
The fourth type of career software engineer is when someone created a software, doesn't sell it but use it as a tool for other business activities (such as trading) or perhaps offer it as software-as-a-service. Good examples are..
Julian Assange - who founded Wikileaks
James Harris Simons - developed software for financial tradings.
The success enable is that they become popular and somehow able to make money out of the technologies or platforms that they owned by not directly selling software license.
The common critical success factor is the sense of ownership and these people usually work alone or in a very small team, usually two or three person. I think two forms the best odds, just like Google.
The idea of working for a company and doing programming without ownership may not last one long, because one doesn't feel the ownership. And it eventually kills the passion.
And if you belong to either one or more of these four categories, you will have a blessing career developing software. The first two categories are hard entries, one has got to be the best in the industry while I think the third and fourth type are within reach of most passionate software developers. Most people are capable of becoming the fourth type if you can survive the initial stage of having not enough money while doing R & D.
Make your choice and good luck.
Remember. Ownership, ownership, ownership.

How to Analyze Turbomolecular Pumps with COMSOL Multiphysics®
by Christopher Boucher
A turbomolecular pump is a type of mechanical vacuum pump that is capable of reaching ultrahigh vacuum (UHV) conditions. Specialized numerical methods are required to model gas flows at such low pressures because the gas molecules rarely collide with each other. The COMSOL Multiphysics® software offers two distinct computational methods for the simulation of highly rarefied gases: the angular coefficient method and the Monte Carlo method. In this blog post, we introduce a Monte Carlo simulation of a turbomolecular pump stage.
Editor's note: This blog post was originally published on August 9, 2017. It has since been updated to reflect new features and functionality.
Understanding Vacuum Systems
Vacuum technology is found in many high-tech industrial applications, such as the fabrication of semiconductor chips. Vacuum environments are also essential in fundamental research; for example, a particle accelerator would not work at atmospheric pressure because the particles being accelerated would collide with the surrounding air molecules much too often.
A typical vacuum chamber.
In a vacuum environment, the absolute pressure of the gas is much lower than the typical atmospheric pressure at sea level, which is about 101,325 pascals (Pa) or 14.7 pounds per square inch (psi). The atmosphere is mostly nitrogen and oxygen, but when dealing with vacuum chambers, we must consider every species involved. Even the outgassing (sublimation and evaporation) from walls, fittings, and lubricants can have a significant effect on the vacuum chamber pressure.
A vacuum pump is used to remove gas from the chamber, thereby reducing the chamber pressure. Many different types of vacuum pump are available, including:
Ion pumps
It is very common for two or more different varieties of pump to be used in tandem, each suited to a particular pressure range. For example, a rotary vane or piston pump can vent air at atmospheric pressure while reducing the vacuum chamber pressure to less than 0.1 Pa or so. A turbomolecular pump, on the other hand, can achieve UHV conditions (less than 10-7 Pa) but does not work properly at atmospheric pressure. To reduce the pressure all the way from atmospheric pressure to UHV, then, you could first reduce the pressure to 0.1 Pa using the rotary vane pump (called a roughing pump when used in this way) and then reduce the pressure from 0.1 Pa to 10-7 Pa using the turbomolecular pump.
A turbomolecular pump.
Note that a perfect vacuum cannot be achieved in practice. A cubic meter of air at atmospheric pressure and room temperature has more than 10 septillion (1025) molecules. Even at UHV, a cubic meter of air still contains trillions of molecules! The goal is not to remove all of the air molecules, but just to remove enough of them so that they don't impede the experiment or manufacturing process taking place inside the chamber.
Rarefied Gas Flows in Vacuum Systems
A turbomolecular pump will only work if the gas flowing through it is a free molecular flow. In other words, the gas pressure must already be low enough so that the molecules hit the surrounding surfaces much more frequently than they collide with each other. Therefore, this pump is only used to achieve UHV conditions after a roughing pump has already reduced the pressure to about 0.1 Pa.
Generally, when we think about airflow, we envision a continuum flow. When air flows into a room through a narrow passage, this puff of air spreads out and may create recirculation regions on all sides. When a stream of moving air reaches an obstruction, we expect it to flow around the obstruction, filling the empty space behind it. The air behaves in this way because the nitrogen, oxygen, and other gas molecules in air collide with each other billions of times per second.
At extremely low gas pressures, the gas behaves as a free molecular flow that is dominated by molecule-wall collisions instead of molecule-molecule collisions. If the gas is released into a large open space from a narrow aperture, then rather than spreading out in all directions due to intermolecular collisions, most of the molecules will fly out in nearly the same direction — a phenomenon called molecular beaming.
When the gas molecules strike a surface, they may get adsorbed by the surface or reflected away from it. Molecules are reflected by the surface in random directions even though the surface may appear perfectly smooth to the naked eye. A fair approximation is to assign a probability distribution to all of the different possible reflection angles. Usually, this probability distribution function is symmetric around the direction normal to the surface.

Taking a Look Inside Turbomolecular Pumps
If you strike a ball with a flat board or a paddle, the ball will bounce in different directions depending on the angle of the paddle as it makes contact. This is the basic operating principle of a turbomolecular pump.
The pump consists of many rings, stacked on top of each other, all lined up along a common axis. Some of these rings rotate around the axis and are called rotors; others are held in a fixed position and are called stators. A typical design may contain many pairs of alternating rotors and stators. Within each ring are many narrow, inclined blades. Generally, each blade in the ring is inclined at the same angle and equally spaced, so if there are N blades, the ring has N-fold axial symmetry.
Because of the inclination of the blades in a rotor, when a molecule hits a blade, it is more likely to bounce out of the rotor in one direction than in the opposite direction. This behavior is illustrated in the following figure for a single rotor with no adjacent stators. Suppose this ring of blades is rotating counterclockwise, as indicated by the red arrows. It is more likely that a molecule will hit the underside of one of these blades rather than the top side. These molecules are then more likely to be deflected downward (in the direction of the blue arrows) than in the opposite direction. Because of this preferential deflection of molecules in a downward direction, the air pressure in the region above this rotor can be reduced.
For the difference in transmission probability (top to bottom versus bottom to top) to be significant, the blade surfaces should move at a speed comparable to or greater than the mean thermal velocity of the molecules. This speed is on the order of several hundred meters per second for most gases at room temperature, but is significantly greater for very light gases such as hydrogen. Thus, when using a turbomolecular pump to reduce the chamber pressure down to UHV, most of the residual gas in the chamber will be hydrogen (Ref. 1).
The blades of a turbomolecular pump are organized into units called stages. A typical pump stage might contain 8–20 rings of such blades (Ref. 2), alternating between rotors and stators. For simplicity, our current model only considers a single rotor.
When setting up a numerical model of a turbomolecular pump, the main purpose is usually to predict its pumping speed and pressure ratio. These can be predicted from the transmission probability of molecules across the ring of blades — that is, the fraction of molecules that exit through the bottom after entering the stage from the top, and vice versa.
Choosing a Numerical Method
In the COMSOL® software, there are two main numerical methods for simulating extremely rarefied gas flows. One is called the angular coefficient method and is used by the Free Molecular Flow physics interface, available with the Molecular Flow Module. The angular coefficient method is a sort of view factor calculation that computes molecular fluxes at boundaries in the model, assuming that the gas molecules will only collide with walls and never with other molecules. The main drawback of the angular coefficient method is that it is "quasistationary" — that is, it ignores the finite time-of-flight of the molecules, which is an important factor here because the blades can easily reach speeds of several hundred meters per second, comparable to the molecular speeds.
In order to fully account for the motion of the blades in the turbomolecular pump, we will instead be performing a Monte Carlo simulation using the Mathematical Particle Tracing interface available with the Particle Tracing Module. In a Monte Carlo model, we solve for the motion of individual molecules in the gas by solving Newton's laws of motion. The true number of individual molecules in the pump might be far too large to model each molecule individually, due to limitations in computational cost, but we can take a representative sample of the molecules — say 100,000 — and then extrapolate the results for the entire population of molecules.
A Monte Carlo simulation is used to predict the transmission probability of gas molecules across a simplified turbomolecular pump stage, consisting of a single rotating ring of blades. As we discussed earlier, a typical pump rotor containing N blades will usually exhibit N-fold rotational symmetry. Therefore, we can further simplify the model and reduce the computational cost by only considering the molecules that pass through a single gap between two adjacent blades.
The gap between the blades is also bounded by two cylindrical surfaces, the inner root wall and the outer tip wall. You might notice from the previous two figures that the actual space that the molecules can travel through is not the full disk, but just an annular region some distance away from the axis of rotation. This is because the velocity of any point on the blade is proportional to its radial distance from the center,
\textrm{Blade velocity} = \textrm{Angular velocity} \times \textrm{Radius}
So, no matter how fast the rotor spins, you'd get diminishing returns from trying to move the root wall closer to the axis of rotation.
The practical limit on the angular velocity is somewhat less than 100,000 revolutions per minute (Ref. 1).
Choosing a Frame of Reference
At this point, our simulation domain is just the empty space bounded at the front and the back by the adjacent blades, and on the left and right by the root and tip walls. Gas molecules may enter the domain from both the top and bottom, and our objective is to determine what fraction of molecules released from the top will exit out the bottom, and vice versa.
Here, we encounter another technical challenge: The space between the rotor blades is moving around in a circle. When modeling in a moving domain, you must decide what frame of reference to use in the model. Usually, the choice is one of the following:
Set up the model in the "laboratory" frame of reference. That is, model the rotor from the point of view of an observer standing motionless outside of it and watching it spin. To do so, you'd have to explicitly cause the geometry to rotate over time, perhaps using the dedicated Rotating Domain node. From this point of view, molecules follow straight-line paths as they move from one surface to the next.
Set up the model in a moving frame of reference attached to the rotor. That is, imagine how the molecule trajectories would look if we, the observers, could shrink down and ride one of these rotor blades. In this frame of reference, the paths followed by individual gas molecules may appear to be curved.
In this example, we'll be using the second approach. However, this brings up an additional complication, as we'll see below.
Particle Tracing in a Rotating Frame of Reference
The molecules obey Newton's second law of motion,
\frac{\textrm{d}}{\textrm{d}t}\left(m_\textrm{p}\frac{\textrm{d}\mathbf{q}}{\textrm{d}t}\right) = \mathbf{F}_\textrm{t}
where q is the particle position, mp is the particle mass, and Ft is the sum of all applied forces.
In this example, we neglect gravity, so the net force is zero. But Newton's second law of motion is formulated in an inertial frame of reference, meaning that it will hold true only if the observer is not accelerating. Rotation is a kind of acceleration, so this model is set up in a noninertial frame of reference.
As another way of visualizing inertial vs. noninertial frames, imagine trying to perform a simple physics experiment (say, bouncing a ball or tracking the motion of a pendulum) while on the back of a moving truck. Such an experiment would give the same result if the truck were parked or if it were being driven in a straight line with the cruise control on. But, the experiment would give different results if the truck were speeding up, slowing down, or turning.
If the distance from the root wall to the tip wall is much smaller than the distance from the axis of rotation to the root wall — that is,
\frac{R_\textrm{tip}-R_\textrm{root}}{R_\textrm{root}}\ll 1
then we may, as a first approximation, just ignore the fact that our frame of reference is noninertial.
This is equivalent to treating the ring of blades as if it were actually an infinite straight line of blades, all moving in the same direction. This assumption is made in the Quasi-2D Turbomolecular Pump tutorial model and discussed further in Ref. 3. This simplifying assumption greatly reduces the computational effort involved because it causes the particles to move in straight lines in the frame of reference attached to the blades. This is a fair approximation when the rotor is turning slowly, but it becomes less accurate as the angular velocity of the rotor is increased.
To perform a high-fidelity Monte Carlo simulation, we must respect the fact that our frame of reference is rotating. Fortunately, the Mathematical Particle Tracing interface already provides a dedicated physics feature specifically for this purpose. You can add the Rotating Domain node to your model to define the fictitious forces that arise from tracing particles in a rotating frame of reference,
\mathbf{F}_\textrm{t} &= \mathbf{F}_\textrm{cen} + \mathbf{F}_\textrm{cor}\\
\mathbf{F}_\textrm{cen} &= m_\textrm{p}\mathbf{\Omega}\times\left(\mathbf{q}\times\mathbf{\Omega}\right)\\
\mathbf{F}_\textrm{cor} &= 2m_\textrm{p}\mathbf{v}\times\Omega
These fictitious forces are called the centrifugal force Fcen and the Coriolis force Fcor. In these equations, v is the particle velocity and Ω is the angular velocity of the rotating frame. For simplicity, it is assumed here that the axis of rotation passes through the origin.
Settings for the Rotating Frame node.
Particle Release and Boundary Conditions
By adding the Rotating Domain node to the model, both the centrifugal and Coriolis forces will be automatically defined. All that remains is to define the particle release and boundary conditions.
The molecules are released into the simulation domain using Inlet nodes on the top and bottom boundaries. This model uses the Thermal velocity distribution, in which the initial speed of each molecule is sampled from a Maxwell distribution and its initial direction is sampled following the cosine law.
f(\theta,\phi)\textrm{d}\theta\textrm{d}\phi \propto \sin \theta \cos \theta \textrm{d}\theta\textrm{d}\phi \qquad f(V) = \left(\frac{m_\textrm{p}}{k_\textrm{B}T}\right)^2\frac{V^3}{2}\textrm{exp}\left(-\frac{m_\textrm{p}V^2}{2k_\textrm{B}T}\right)
The blade velocity is then subtracted from the velocity of the released molecules because the gas in the region adjacent to the pump stage has zero drift velocity in the laboratory frame of reference.
Settings for the Inlet node.
The blade walls, root wall, and tip wall all use the Thermal Re-Emission boundary condition. Whenever a molecule hits one of these surfaces, it bounces back into the domain with a new random speed and random direction. The blade walls and root wall are assumed to move with the rotating frame, while the tip wall is assumed to be fixed in the laboratory (inertial) frame. A built-in setting is used to subtract the moving frame velocity from the reinitialized particle velocity for any molecules that hit the tip wall.
Settings for the Thermal Re-Emission node at the tip wall.
The transmission probability is defined as the fraction of the released molecules that will cross from one side of the pump stage to the other, rather than being knocked backward by the blades. When the blades are rotating, we can define two distinct transmission probabilities: the transmission probability in the forward direction (top to bottom in the previous diagrams) and in the reverse direction (bottom to top).
From the transmission probability of the molecules in the forward and reverse directions, we obtain the maximum compression ratio Kmax and the maximum speed factor Wmax,
K_\textrm{max} = \frac{M_{12}}{M_{21}} \qquad W_\textrm{max} = M_{12}-M_{21}
where M12 is the transmission probability in the forward direction and M21 is the transmission probability in the reverse direction.
Let's look at some plots comparing these transmission probabilities to a dimensionless velocity ratio C. This is the ratio of the blade speed (measured at the root mean square or rms radius) to the most probable speed of the molecules in the gas. The molecule speed is a function of molecule mass and gas temperature. In general, molecules move faster in a hotter gas, and lighter molecules move faster than heavier ones. For this reason, turbomolecular pumps are better at pumping out heavier species like argon, nitrogen, and oxygen, but they're somewhat less efficient at pumping hydrogen (Ref. 2).
When the blades are at rest (C = 0), the transmission probabilities for the forward and reverse directions are roughly equal. As the blades begin to spin faster, the probability in the forward direction approaches unity while the probability in the reverse direction approaches zero.
The fraction of particles transmitted in the forward and reverse directions as a function of blade velocity ratio.
We also investigate how the compression ratio and pumping speed are affected by the blade velocity ratio. To produce enough compression and speed, pumps use multiple bladed structures comprised of several disks and different types of blades. Blades close to the chamber inlet are designed to have a high pumping speed and low compression ratio, while blades close to the foreline (the connection to the roughing pump) are designed to have a low pumping speed and a high compression ratio.
When the velocity of these blades increases, as seen in the plots below, the maximum compression and speed factor increase. These plots show excellent agreement with a similar study reported in Ref. 4.

Walking in New Rochelle
New Rochelle in Pop Culture
Home : : NY Outside the C : : New Rochelle
This "Queen City of the Sound" 23 miles North of New York City is East Coast leisure at its best. When you go for a little promenade across its urban areas, not only do you get to live and breathe the well-off, leisure-starved atmosphere -- you also get to see the evolution of History before your eyes.
But history, sweeping and painstakingly preserved as it may be, is a side dish here.
Restful, low-key, this is the perfect counterpoint for the fast and furious streets of Manhattan.
Best Walking City in America
In 1878, former Congressman Joseph H. Starin bought a string of islands in a then-modest, rural city in the South East of the New York state called New Rochelle. In them, he built a theme park called Glen Island -- one of the first to open to the public and the most luxurious of its time, with beaches, a Chinese pagoda, a natural history museum and a zoo.
It was a bona fide success. But what made methodical Starin personally proud was how clean, orderly and decorous his project was known for being. He would often boast of the "middle-class code of conduct" that would bridle the whole Glen Island experience.
Not only is this one of the city's most iconic stories, the image it conveys -- well-off tourists being quiet on an island -- is the most accessible representation of what New Rochelle is.
City Hall fiercely pursues the preservation and restoration of its vintage landmarks (take the famous "Arcade" building in 541 Main Street for instance -- in 1997, the local government was ready to tear down its uncomely facade built in the 1960s only to discover a couple of exquisite 1897 banks of arched windows and vintage terracotta relief work. It was then carefully restored and left that way), which means that certain parts of its streets may strike you as living vignettes of either its rural beginnings as a refuge for French Protestants in the 1700's or its booming development as a self-supported, agricultural city throughout the 1800's.
Or its opening up to America via tourism in the 1900's (the first summer house was finished in 1855 and hosted guests like Charles Dickens). Or its subsequent peak as one of the most sought-after suburban communities for peace-loving New Yorkers who brought the money with them and made New Rochelle the third wealthiest city per capita in America in the 1930's with only 54,000 inhabitants. This prompted the construction of the beautiful Art Deco buildings the city is known for.
It wouldn't have been named one of the 100 Best Walking Cities in America by the American Podiatric Medical Association if it offer miles and miles of ravishing nature reserves and parklands scattered through several tiny islands that can make you feel as far from The Bronx as any Alaskan. This haven of peace and decorum is too cute to ignore. And it's the perfect medicine if the city's hyperactive animation wears you do.
New Rochelle citizens are so proud of their peaceful backwater they are in no rush to catch with the current pace of urban landscaping (or any pace for that matter), making it the ideal location for a walk you will never forget. Let us guide you through the different options.

With air pollution causing an estimated 4.2 million deaths per year worldwide, leaders across the globe are pledging to make their cities greener. Air pollution causes a staggering minimum of 40,000 early deaths in London alone. While nitrogen dioxide levels are falling and could reach legal levels within six years, two million people in London are still living with illegal air pollution levels.
There are a range of startups answering the call with revolutionary ways to reduce our emissions and make our cities better for us and the planet.
Here are our top 10 green transport startups...

Q: Evaluate large file with ^H and ^M characters I have a logfile that contains many ^H and ^M characters, as the process that produces this file updates a text based progress bar.
When using cat the output is evaluated and appears human readable and concise. Below is an example output.
Epoch 11/120
4355/4355 [==============================] - ETA: 0s - loss: 0.0096
Epoch 00011: val_loss did not improve from 0.00992
4355/4355 [==============================] - 1220s 280ms/step - loss: 0.0096 - val_loss: 0.0100

However, the file itself is huge compared to what the actual printed text from cat would suggest (70MB for around 900 lines) of text like above.
Below is a snippet of the actual text contained within the logfile.

Basically, I want to create a file that looks just like what cat produces.
Here's a few things i've tried with limited success:

*

*tr -d '\b\r' < logfile > new_file removes all of the characters, but therefore leaves all of the undesired text.

*cat logfile > new_file effectively just copies the file verbatim with no evaluation of the special characters.

*cat logfile | col -b > new_file is pretty close, but does something odd on one of the repeated lines:

4355/4355 [==============================] - ETA: 0ss--loss::0.0096557
Epoch 00011: val_loss did not improve from 0.00992
4355/4355 [==============================] - 1220s 280ms/step - loss: 0.0096 - val_loss: 0.0100

Any help would be appreciated.
Thanks

A: Posting this as an answer for clarity.
As rowboat pointed out, in this case the command awk -F '\r' '{print $NF}' file works as intended, by removing everything after the last carriage return. Though this is not robust as zevzek pointed out.
I wrote a more robust solution in C++ below.
#include <fstream>
#include <string>
#include <iostream>

using namespace std;

string filter_string(string line, const char *bspace, const char *creturn){

    string new_str;

    for(string::size_type i = 0; i < line.size(); ++i) {
        // Step back if current string not empty
        if (line[i] == *bspace){
            if (new_str.size() != 0){
                new_str.pop_back();
            };
        // Reset on carriage return
        } else if (line[i] == *creturn){
            new_str = "";
        } else {
            new_str += line[i];
        };
    }

    return new_str;
};

int main(int argc, char* argv[]){
    const char backspace = '\x08';
    const char creturn = '\r';

    if (argc != 2){
        cerr << "USAGE: " << argv[0] << " [src]" << endl;
        return 1;
    }

    // Filter lines in file
    string line;
    ifstream infile(argv[1]);
    while (getline(infile, line)){
        cout << filter_string(line, &backspace, &creturn) << endl;
    };

    return 0;
};

Here each character in each line is iterated over, and if a ^H is present, the string is pushed back one (if not already empty), and if a ^M carriage return is present then the string is reset. The output is sent to stdout which can then be piped to a file.

A: sed 's/.*\x0d//' logfile
Seems to do what you ask for.
Note that col -b fails because it is ignoring the whitespace:
$ echo $'--------\r1st try\r2nd   \r3rd\n' | col -b

BEWITH029LP
Recorded in Philadelphia in 1969, The Deirdre Wilson Tabac's sole album is a beautiful blend of funk, jazz and soulful pop. Possessing the complex grooves, thrilling breaks and ethereal weirdness that The Rotary Connection pedalled so brilliantly, the LP failed to connect with audiences upon its original release.
In the decades since, it has deservedly attracted a considerable cult following. However, almost inevitably, it has become increasingly tricky to pick up a copy in good condition for anything less than eye-watering sums. As such, we're delighted to present the first officially licensed vinyl reissue of this undoubted masterpiece of freaky funk-rock, limited to just 500 copies.
The Tabac were, in fact, a trio. Discovered, managed and produced by Svengali Sonny Casella (who'd earlier managed garage band The Magic Mushrooms), they comprised Deirdre Wilson, Stu Freeman (formerly of said Mushrooms) and Barbara Payne (formerly with the James Brown Revue). They were backed by session players including jazz guitarist Chuck Anderson, bassist Hugh McDonald and keyboardist Roy Bittan (who went on to be a long-term Bruce Springsteen sideman).
Their first single coupled two fine Casella compositions, each featuring powerhouse vocal workouts; the supremely funk-fuelled blues beat of "The Other Side Of Life" and the psychedelic-flavoured "Look In My Face" - both of which are featured here. This 7" picked enough up airplay to merit an album, which duly appeared early the following year, but, as is often the way with these lost classics, it received barely any press. Correspondingly, sales where low and the trio didn't last long.
And herein lies the real tragedy. The rest of the LP deserves to be heard from start-to-finish - it's that good. A beguiling mix of funky folk and rocky jazz tracks, with some deep, string-drenched harmony soul ballads and a handful of remarkable covers elegantly presented througout. Indeed, they put some sauntered head-nod funk into The Beatles' "Get Back" whilst tearing through a version of "Sittin' On The Dock Of The Bay" which gives Otis' original a real run for its money.
But the real standout cut for most - with its soulful, haunting vocals, swinging hammond organ and stabbing horns, is the incredible 6/8 time jazz dancer "I Can't Keep From Cryin' Sometimes." Staggering.

Q: Multicast for Tomcat servers on Google Cloud Google Cloud VPC networks only support IPv4 unicast traffic [1], they do not support broadcast, multicast or IPv6 traffic within the network.  I have several tomcat servers and I'd like to group them into a cluster, but without multicast it seems I can't.
Is there any way to make this Tomcat cluster working in the Google Cloud VPC?
[1] https://cloud.google.com/vpc/docs/vpc

A: You can use overlay network deployment to have mcast/bcast support inside.
"Third-party partner solutions such as Weave Net, Cohesive Networks, or Ravello can help you enable these features by using their overlay network solutions. Or you can build your own overlay network by using open technologies such as VXLAN."
REF: https://cloud.google.com/solutions/delivering-aggregated-travel-data-with-minimal-latency

A: I think it's better to use static cluster.
There are 2 types of cluster:
Static Tomcat Cluster
Dynamic Tomcat Cluster
In static cluster there is not need multicast, because each tomcat we statically defined/configured the other instances. But dynamic Cluster we are not defined anything. so each tomcat in that cluster some how to identify the other tomcat instances.
You can find more details here: https://www.ramkitech.com/2012/11/tomcat-clustering-series-part-3-session.html

Ngqotheni v Desert Charm (Pty) Ltd t/a Phangisa Transport (58/2013) [2013] SZHC 125 (01 July 2013);
Case No. 58/13
CEDZINDZABA NGQOTHENI PLAINTIFF
DESERT CHARM (PTY) LTD
t/a PHANGISA TRANSPORT DEFENDANT
Neutral citation: Cedzindzaba Ngqotheni vs Desert Charm (Pty) Ltd t/a Phangisa Transport (58/13) June 2013 [SZHC] 125
Coram: OTA J.
Heard: 24 JUNE 2013
Delivered: 1 JULY 2013
Summary: Summary judgment application: No triable issues raised in opposing affidavit: Summary judgment granted.
OTA J.
[1] The facts of this case are as follows:- In the month of May 2010 in Mbabane, the Plaintiff and Defendant entered an oral agreement wherein the Plaintiff leased to Defendant motor vehicles for conducting courier services between Swaziland and South Africa. The Plaintiff was to be paid the sum of E1,000.00 (One Thousand Emalangeni), daily for each vehicle leased to the Defendant. Subsequent to this agreement, the Directors of the Defendant company resigned and the company was taken over by Linda Vilakati, Gugu Dlamini and Sarah Simons who continued to honour the terms of the agreement between the parties for a period. The Defendant however subsequently defaulted in payment of a total sum of E30,421.00 (Thirty Thousand four Hundred and Twenty One Emalangeni) in respect of which the Defendant's Directors Sarah Sulman and Gugu Dlamini, signed an acknowledgement of debt agreement with the Plaintiff which is exhibited in these proceeding as annexure C1. The Defendant also failed to pay Plaintiff for rentals for 27 December 2012 as well as 3, 7, 8, 10, 11, 14 and 15 January 2013, which when the sum of E2 719 which the Defendant spent at the brake shop to fix the motor vehicles is deducted, brings the total amount owing by the Defendant to the sum of E35,702.00. The Defendant failed to pay this amount despite demand.
[2] It is against a backdrop of the aforegoing facts that the Plaintiff took out simple summons against the Defendant claiming for the said sum of E35,702.00, 9 % interest rate per annum a tempore morae, costs of suit at attorney and own client scale as well as further and / or alternative relief.
[3] The Defendant filed a notice of intention to defend. The Plaintiff thereafter launched his declaration simultaneously with a summary judgment application in which he claimed for the said sum of E35,702.00, interest and costs of suit. The Defendant for its part reacted by filing an affidavit resisting summary judgment.
[4] It is a well established jurisprudential position that summary judgment is a stringent and extraordinary remedy which must be approached with extreme caution in order not to foreclose a defendant with a bona fide defence from defending the action.
[5] Rule 32 thus requires the Court when faced with a summary judgment application, to scrutinize the affidavit resisting summary judgment to see if it raises a triable issue or issues that will emasculate summary judgment. Once the Court comes to the conclusion that a triable issue is raised, it must deny summary judgment and allow the parties proceed to trial. See Zanele Zwane v Lewis Stores (Pty) Ltd t/a Best Electric, Civil Appeal No. 22/07, Mater Dolorosa High School v R.J.M. Stationery (Pty) Ltd, Appeal Case No. 3/2005, Protronics Networking Corporation and Another v Swazi Wire Industries (Pty) Ltd and Another Civil Case No 74/2012, Nedbank (Swaziland) Ltd v Baslam Investments (Pty) Ltd and Another civil Case No. 2016/11.
[6] I have in compliance with the requisites of this procedure carefully considered the affidavit resisting summary judgment which is launched by the Defendant and I see no triable issue raised therein that can disable this application.
[7] This is because the Defendant admitted liability for the sum claimed in paragraph [8] of the said affidavit in the following words:-
"8.1 The Defendant does not deny that it is indebted to the Plaintiff in the sum of E35,702.00 (Thirty five Thousand Seven Hundred and Two Emalangani) but denies that the said amount is now due, owing and payable. The Defendant avers that the Plaintiff was in the employs of the defendant as a Manager on a contract basis and same expired on the 15th January 2013. The Defendant did not renew the contract because of financial difficulties which the Plaintiff is clearly aware of and duly informed the Plaintiff of same. The Plaintiff was informed that the monies owed to him would be paid in course and in installments as in the past he had been receiving his payments in installments.----''
[8] When this matter was heard, Ms Ndlangamandla who appeared for the Defendant conceded that the aforegoing admission is justification for the grant of summary judgment and that whatever mode of installmental payment the parties had negotiated and were still negotiating cannot defeat the application.
[9] Now, learned counsel for the Plaintiff Mr Manzini seeks punitive costs on the attorney and own client scale on the basis that the whole opposition to the application is a dilatory stratagem geared at stultifying the Plaintiff's early dance of victory. Ms Ndlangamandla is opposed to this application on the grounds that the Respondent has all along admitted liability and the matter only came to Court because the parties failed to agree on the installements payable.
[10] I am persuaded by Ms Ndlangamandla's entreaties. There is clearly no denial of liability as I have already found, to warrant such punitive costs. This case is easily distinguishable from the case of Protronics Networking Corporation and Another v Swazi Wire Industrial (Pty) Ltd, urged by Mr Manzini. In that case the Defendant entered a notice of intention to defend and urged frivolous defences even though the Plaintiff's case was clearly unanswerable. The Court a quo granted summary judgment for the Plaintiff. The Defendant launched an appeal against the decision. In upholding the decision a quo the Supreme Court imposed punitive costs against the Defendant who was Appellant as a mark of its disapproval for his dilatory stratagem. This is however not such a case.
[11] On these premises, this application succeeds. I make the following orders:-
1. Summary judgment is entered for the Plaintiff in the sum of E35,702.00.
2. Interest thereon at the rate of 9% per annum at tempore morae
3. Costs of suit.
For the Plaintiff: N. Manzini
For the Defendant: N. Ndlangamandla
