6/1/2023 0 Comments Whatsapp for mac textingUsing Web Browserīefore the desktop app was available, there’s the web version of WhatsApp. Here are several methods other than using the official desktop version that you can use to use WhatsApp on your Mac. The long gap between the first time debut of WhatsApp on mobile and the availability of the desktop app causes users and many developers to try to come up with their own solutions. It’s less convenient but the company claims this approach is taken to increase the security. So to use it, you need to have the mobile version running and connected to the internet. Similar to the web version of WhatsApp, this desktop app is also acting as the extension to the mobile app and not as an independent entity. Follow the instructions according to your phone model.Īfter the quick QR scan, the app will sync all the conversations between the desktop and the mobile version. Mac users can also get it from the Mac App Store, but the one from the official website is usually more recent as getting approved on the Mac App Store could take some time.Īfter downloading and installing the desktop app, open it and scan the QR code using the mobile app. Users can download the app on the official web page. After years of turning blind eye to the desktop, the company releases the desktop app. If you are a Mac user and you’d love to use WhatsApp on your Mac machine, what can you do? How to install WhatsApp on Mac? Finally, the Official Desktop Appįortunately, WhatsApp finally realizes that their users are not always on mobile. WhatsApp could lose this audience segment to the competitor if there’s no love left for the desktop. There are people who prefer to use the desktop version of their favorite messenger app simply because it’s more convenient and takes less time in composing messages. But if there’s one thing that lacks from the service, it’s that it focuses too much on mobile. With messages peaking at 64 billion, there’s no doubt that WhatsApp is one of the most popular messaging platform available today.

6/1/2023 0 Comments Goldencheetah apowerRegardless of the equation, the real trouble with W’ is the unmanageable error in its calculation in the long run. If the differential approach doesn’t have a tuning parameter for response time, it’s only because it was fixed and not made adjustable to the user. The difference in the two approaches is most likely simply that they use a different value for tau. The instantaneous differential proportionality IS tau. To get a glimpse of this you only need to look at the slope (proportionality constant, ie derivative, ie differential) of a (1-e^-(t/tau)) graph at t=0. That proportionality constant is equivalent to tau. In a differential approach there is a proportionality constant that determines the amount of change in proportion to the present difference between present power and steady state power (CP). In the differential form it may be less obvious that it’s actually a mean time, to someone who isn’t as expert with the math, possibly even the person who wrote it, I don’t know. They both have a “TAU” (pronounced “mean time”) built into them. Enjoy your ride! Tags: Connect IQ, Cycling, Garmin, Power, W prime Post navigationįor simple exponentials there is nothing necessarily different about a differential or integral calculation. Anything else ?įeel free to leave a comment to this entry for any feature request, bug, advice or question. Yep, all the source code is available on Github here. You will have to change the three parameters to suit your values (CP, W’ and Method). Then, go to the Connect IQ store on Garmin Connect Mobile, or directly at this page: and get the stuff. Compatible devices with powermeters and Connect IQ are, at the time of writing are: Where can I get this app ?įirst, you will need to ensure your Garmin device is compatible with Connect IQ apps, and has an updated firmware. Science has not yet validated one against the other. The only advice I can give you is: try both formulas and choose the one you prefer. Values here are for a mixed field test (5min VO2Max, 10 min recovery, 20 min FTP test). The blue line is the differential formula (the one used by default in GoldenCheetah). What is the difference between the two formulas? This one: It’s known as “ differential” and available starting from version 1.2 on my data field, but you have to configure “compute method” parameter to “differential” instead of “integral”. It’s now the default method on GoldenCheetah. The second method, by Froncioni / Clarke only use current power to compute recovery, so with this formula, W’ Bal will usually regenerate faster, and decrease faster as well. This value is known as TAU, and it’s based on the activity history. On my data field, it’s called “ integral” and it’s the default method, just because I prefer it… This formula uses another parameter to define the speed at which W’ is regenerating when the power is below CP. It was the one implemented in GoldenCheetah at the beginning. Initially, the only known formula to get W’ Bal was the one from Dr Skiba. Compute methods (the real maths behind the data) Of course, if you already know your FTP value, you can use it as CP. Based on that, it will give you an estimation of W’ and CP. Here you can enter you maximum amount of watts for a short effort (3-5min) and a long one (15-60 minutes). To estimate your CP and W’ values (if you don’t already know them), GoldenCheetah provides a tool in the “ Tools -> Estimate CP and W’” menu. To be able to compute W’ Bal, we need two values: You can note on this chart the peaks above CP (the line is going down, as the amount of remaining W’ decrease), and the periods where power is below CP (the line is going up, as the amount of remaining W’ increase). Skiba theory, and this value was then implemented on the GoldenCheetah software, on the “Charge” chart of a ride: So if you ride long enough below CP, W’ will be at 100% again.Īll these variation in W’ are expressed as “W’ Bal” in the Dr. As soon as your watts get lower than CP, W’ will “regenerate”, and the value will increase again. So if you push on the pedals harder than CP, W’ will decrease. At my level, I use to consider my CP and FTP as the same value. The limit at which you will start lowering the W’ is known as CP (Critical Power). But if you push harder, you will start using this energy. While you’re riding at low intensity, W’ remains at it full level, and you can theoretically continue riding at this intensity for a while. This value, known as W’ (or W prime) is measured in joules. To make it simple, assume that a cyclist have a given amount of energy at the beginning of a ride. Let’s dig a bit into this interesting value… This app is designed to display the remaining value of W’ during a ride on the cyclist’s device. A few weeks ago, I released the first version of my W’ Bal datafield on Garmin Connect IQ. This is because CV involves having a Lactobacilli overgrowth and many probiotics contain Lactobacilli. We advise everyone to stop consuming or inserting probiotics while dealing with Cytolytic Vaginosis because the wrong ones can make things worse. Please help us by staying in touch as we are really interested in hearing your results and experience with using these. Unfortunately there isn’t a lot of awareness or knowledge about CV and we are trying our best to change this. It’s definitely not considered a permanent disorder. On average we see most women resolving this condition within a few weeks or less. These work by increasing the vaginal pH and most women get instant relief and permanently resolve their Cytolytic Vaginosis symptoms. Please insert 1 baking soda suppository twice a week or every 3 days if you are tolerating them well. Wearing period undies can also help draw away the discharge from your skin. Or try using some nappy rash cream with zinc to protect your membranes from your discharge. If your vulva feels really irritated you can try using some otc hydrocortisone cream for the inflammation. If you have dryness or irritation use some lube, V Magic or a vitamin E insert. These are a made to order product made just for you! These work by increasing the pH in a gentle way.

Some areas like Chicago Meigs Field and Northeastern USA are paid, but highly detailed. Previously it covered California, Nevada, and Arizona. The free DLC comprises of high-resolution assets for the southwest US, which now includes Utah and Colorado. As with any flight simulator, there’s some paid and free DLC. This provides a healthy selection of aircraft from personal, professional, and military (both historical and modern). There’s a variety of aircraft, with 16 included aircraft including the Aermacchi MB-339, Airbus A320, ASG 29 glider, B737-500, B747-400, Baron 58, C172, Corsair F4U, Extra 330, F-15 Strike Eagle, F-18, Jungmeister, King Air C90 GTx, Learjet 45, P-38 Lightning, Pitts S-2B biplane, Sopwith Camel, and Swift S1 glider. So I took a deep breath, pushed my expectations aside and set out to discover new lands. Overall, it felt like a simple flying game, and while I’m totally fine with flying games (and even think they are needed to get younger people into this hobby), I was still wondering what Aerofly FS2 could offer me over X-Plane 11 and Prepar3D. For a start, the user interface appeared really large on my 1920×1080 screen (as if it was made for a much smaller touch screen), plus several options I was used to seeing in simulators were missing, especially regarding weather, starting position, and flight planning. To be honest, my first impressions were still rather negative when I first installed Aerofly FS2. That was it, for quite some time, until Dominic emailed me with ideas of a possible review. Positive things I read about, like very good frame rates (FPS), I rejected when I saw screen shots of the scenery: “Well, that’s just static photo scenery”, I said, “autogen only in very few areas, everywhere else is flat, no animations of car traffic or water – no surprise really that FPS are good!” Microsoft Flight Simulator 2020 You see, I had judged Aerofly FS2 way back when it was initially released as early access, and my ill informed decision was based solely on some screen shots of the user interface, weather settings (simpler even than X-Plane), and aircraft without (it seemed) any system depth. I did not know much about Aerofly FS2 before I started this review, but like most people with limited information, I came to an uninformed opinion and simply said, “I won’t use that”. Aerofly FS 2 Flight Simulator comes from IPACS, a German developer who previously released Aerofly FS and Aerofly RC that lay the foundation of what makes this such a solid game. Death Valley and all of the intricate details of the Californian desert is another particularly impressive area on offer. Furthermore, such iconic cities of California as San Francisco, Oakland, and Los Angeles are meticulously detailed, including many skyscraper buildings and 3D trees below. You can expect to see many of the major tourist attractions such as the Golden Gate Bridge with the beautifully textured water of the Pacific Ocean below it – although we should note, the water itself is “still shot” and not animated as in other flight sims. For example, if we look at the original default scenery package, the Southwestern states of the United States – which covers essentially California up to the state of Washington, including Nevada and Arizona. And what’s more, for basic default scenery, the detail on offer is really quite impressive. There are several add-ons for purchase, however, including the Northeastern region of the United States and Switzerland. In the basic download, high res sceneries of Utah, Colorado, and much of the Southwestern United States are available. After all, aside from the vehicles themselves, it is virtual skies you will be flying through and the visuals you will witness from the air that makes one program stand out from another. 22 aircraft included: EC135 and Robinson R22 Beta II helicopters, F-15, F-18, Aermacchi MB-339, King Air C90 GTx, Learjet 45, Extra 330, Pitts S-2B biplane, Bücker Jungmeister, Corsair F4U, P-38 Lightning, Sopwith Camel, ASG 29 and Swift S1 gliders, Dash-8 Q400 (available as free DLC), Highly detailed and interactive 3D cockpits, Adjustable cockpit lighting at night time, Realistic flight physics, Interactive Flight school for learning the basics of flying, High resolution aerial images and over 200 airports for the South West of the United States, World wide elevation and aerial images, Display terrain features like mountains, lakes and cities for easy VFR navigation, Route editor for easy flight planning.

I have seen users pushing those thin nozzle cleaner wire from the nozzle hole and up. After adding an inexpensive silicone sock to my heater block, the problem is resolved. I started cleaning it, initially with a wire brush and later using a strip of corrugated cardboard as a "squeegee" to scrape off accumulated filament. I really wasn't aware of this starting out until I realized my block was filthy. The dirtier the block, the worse it gets. The leaking can aggravate the catching as a tiny bit of leaked filament can snag printed filament and compound the problem. The dots can come from the leak on top, or filament catching during printing underneath. Black dots disappeared for a day but then they show up again on the next day. I also used a brush to clean the bottom of the Heater block (the area near the Nozzle). Looking at the underside, they can probably determine if filament is oozing from "somewhere" besides the nozzle itself, that alone is sufficient to diagnose a poorly tightened nozzle with relative certainty. Removing the cooling fan shroud and getting light into the gap between the block and heatsink is more complex. Taking a picture of the underside is simple enough. Support always has to balance their need for information with what they can reasonably ask upset users to do. It does not show the area between the "top" of the Heater block in the illustration and the Heatbreak. The photo I took only shows the bottom of the Heater block (the surface near the Nozzle). After seeing the photo, he asked me to tighten it. One confusion I have is that Prusa Support asked me to take a photo at the bottom of the extruder. The only way filament can collect up there is if it oozes out the top of the block. Am I correct that if I see some filament at the gap between the Heatbreak and the Heater block, it means there is a leakage? Posted by: Thanks for the nice illustration. Use a toothpick to clean out around the wires if needed. If so, you can use a soft brass brush to carefully clean it off, taking care around the delicate wires. See if you have old filament accumulated around the hotend. Remove the part cooling fan and inspect the hotend with good light. I use a bit of papertowel wrapped around a bit of cardboard to gently clean around the hot nozzle. In the case of a non-hollow heatbreak, where the tube only goes partially down inside, and you have metal to metal contact with the nozzle, it might just have come loose after long usage and started to seep thru the threads in the heatblock. In my case, it seeps out below the heatblock, in the threads of the nozzle so i let it be for now, and just wipe down the nozzle before each print. I have now only a tiny leak with one brand of higher end filament that are more runny then the generic pla i normally use. I noticed i had quite a severe leak and disassembled it, and found a tiny speck of ptfe granulate. On my Flsun QQs it it a e3d v5/6 j-head mk8 type with hollow heatbreak that lets the ptfe-tube go down and butt up againt the top of nozzle. You can play Scorched3D on an OpenGL-capable hardware using open-source operating systems, such as Linux, FreeBSD, as well as Mac OS X, Windows and Solaris.Posted by: guess that would depend on your type of hotend. It’s up to you whether you want to play Scorched 3D as a “shoot ‘em up” game where you try to destroy other tanks or if you want to delve into the complex strategies of the game. Playing online adds some real-time excitement as you pit your strategies against twenty-four other players using random environments and user maps. You can play the game using real-time strategy against the computer or with other players using the internet and LAN. Many more mods are available at the Scorched3D wiki. This highly moddable game has amazing 3D graphics and sound and comes with the Armored Warfare Evolved and Apocalypse mod, which features enhanced weapons and landscapes. With several 3D landscape choices that you can utterly destroy, along with jets, ship and artillery, it’s incredible that this single/multi- player artillery game is free. If you remember the DOS version of Scorched Earth, then the 3D visual effects in the latest Scorched3D game will blow you away. 5/31/2023 0 Comments Horae racingPETA is working hard to tackle horse-racing cruelty. And despite these staggering numbers, the racing industry continues to churn out nearly 20,000 Thoroughbred foals annually. are trucked to Canada and Mexico and slaughtered each year. An estimated 10,000 “unprofitable” or simply unwanted Thoroughbreds from the U.S. A horse named Who’s Bluffing was claimed 12 times in his career-including three times by the same owner.īecause no one individual is committed to a horse throughout his or her lifetime, each day brings new uncertainty for these animals. In a two-month period in 2011, over 2,000 horses were callously sold through claiming races. Some races, called claiming races, allow for horses to be purchased and taken away by a new owner immediately after the race, giving previous owners little control over where horses end up. Ownership turnover is rampant, and most Thoroughbreds are bought or “claimed” multiple times during their careers. Treated Like CommoditiesĪs most owners and trainers have little more than a short-term financial interest in horses, there is little continuity and accountability over Thoroughbreds’ lifetimes, leaving them to suffer terribly. In 2015, in New York alone, more than 250 Thoroughbreds endured injuries or fatal breakdowns during races. Not surprisingly, every week, an average of 24 horses experience fatal breakdownsat racetracks across the country, and this number doesn’t even take into account the horses who are discarded by the racing industry when they’re no longer considered profitable. In an attempt to decrease the bleeding, many horses are given a drug called Lasix or Salix, a diuretic with performance-enhancing qualities. Many horses-fittingly called “bleeders” by the racing industry-will bleed from their lungs, a condition known as exercise-induced pulmonary hemorrhage. Pushed beyond their limits, most horses are subjected to cocktails of legal and illegal drugs intended to mask injuries and artificially enhance performance. Months later, jockey Roman Chapa-who was previously suspended for using a nail on a horse-was charged with a felony for race-fixing after using a shocking device during a race. In 2013, PETA documented that top trainers and jockeys admitted to having used illegal electro-shock devices on horses. At a 2008 race, the horse named Appeal to the City hemorrhaged around her eye when jockey Jeremy Rose “engaged in extreme misuse of the whip.” During his Kentucky Derby win, American Pharoah was struck with a whip at least 32 times by jockey Victor Espinoza. Whip use is standard practice in the U.S., with little more than lip service handed out to extreme violators in most states. Horses used for racing are forced to sprint-often under the threat of whips and even illegal electric-shocking devices-at speeds so fast that they frequently sustain injuries and even hemorrhage from the lungs. 5/31/2023 0 Comments Amazing hamster mazeYOU DID IT!

The ions flow through ATP synthase via chemiosmosis to form molecules of ATP, which are used for the formation of sugar molecules in the second stage of photosynthesis. This action builds up a high concentration of ions. The energy travels to the reaction center that contains chlorophyll a and then to the electron transport chain, which pumps hydrogen ions into the thylakoid interior. A photon strikes the antenna pigments of photosystem II to initiate photosynthesis. The pigments of the first part of photosynthesis, the light-dependent reactions, absorb energy from sunlight. 8.2 The Light-Dependent Reaction of Photosynthesis In prokaryotes, such as cyanobacteria, the process is less localized and occurs within folded membranes, extensions of the plasma membrane, and in the cytoplasm. Eukaryotic autotrophs, such as plants and algae, have organelles called chloroplasts in which photosynthesis takes place, and starch accumulates. Photosynthesis uses carbon dioxide and water to assemble carbohydrate molecules and release oxygen as a waste product into the atmosphere. Only certain organisms, called photoautotrophs, can perform photosynthesis they require the presence of chlorophyll, a specialized pigment that absorbs certain portions of the visible spectrum and can capture energy from sunlight. Because of photosynthesis, living things gained access to sufficient energy that allowed them to build new structures and achieve the biodiversity evident today. By harnessing energy from the sun, the evolution of photosynthesis allowed living things access to enormous amounts of energy. The process of photosynthesis transformed life on Earth. 5/31/2023 0 Comments Cathode ledYou can change the terminal and check whether you have common anode. If your LED glows then it will be common cathode type. So you need to place the Black Wire of the multimeter to the longest lead and place the Red wire to the other terminals one by one. In the RGB LED, the longest pin will be the common terminal (in comm0n cathode LED the longest pin is an Cathode, similarly for the common Anode). In the multimeter, rotate the knob to Diode testing mode (Diode Symbol mentioned). You can use a multimeter to find out as well as the LED Colors pins too. How to check the type of RGB LED with multimeter? In a Common Cathode RGB LED, all three LEDs share a negative connection (Cathode). For a white light, you’d set all three LEDs to the highest intensity. The anode and cathode on a physical LED can be distinguished by identifying some specific characteristics the anode pin is longer than the cathode pin and the cathode side of the plastic diffusion lens is typically slightly flattened.With an RGB LED you can, of course, produce red, green, and blue light, and by configuring the intensity of each LED, you can produce other colors as well.įor example, to produce purely blue light, you’d set the blue LED to the highest intensity and the green and red LEDs to the lowest intensity. Since LEDs are polarized devices, they must be placed in the circuit with the correct orientation the anode must be at a higher voltage potential than the cathode in order for the diode to emit light. LEDs are available in a number of colors the Digilent analog parts kit contains red, yellow, and green LEDs. If the LED voltage is less than the threshold voltage, no current flows and no light is emitted. When the voltage difference across the LED exceeds the threshold voltage of the LED, current flows through the LED and light is emitted. If the LED doesn't light at or below 3 volts, the LED lead that connects to the resistor is the negative lead, or cathode, and the positive end, or anode, of the LED is the lead that connects to the negative terminal of the battery. The small LED chips are secured inside a plastic housing and emit light at a given frequency when a small electric current (typically 10mA to 25mA) flows through them. Observe if the LED lights at each 0.3 volt increment until you reach 3.0 volts or the LED begins to emit light. Light emitting diodes, or LEDs, are a specific type of diode which emits light when current passes through them. Voltage rectifiers, for example, can convert a sinusoidal signal (with both positive and negative components) to a voltage which is purely positive. The ability of a diode to conduct current in only one direction is used in a number of common circuits. If the diode voltage equals the threshold voltage (plus a small amount) in an ideal diode, then unlimited current can flow without causing the voltage across the diode to increase. 2.Īs an aside, if the cathode voltage is greater than the anode voltage, the diode is said to be reverse-biased and no current will flow 1). In a common cathode RGB LED, the cathode of the internal LEDs are all connected to the external cathode lead. Update: As of January 2018 weve moved to new supplier for these LEDs and so can now. Use this one LED for three status indicators or. If the anode voltage is not at least Vth greater than the cathode voltage, no current will flow through the diode, as shown in Fig. Use this one LED for three status indicators or pulse width modulate all three and get mixed colors Available in both clear and diffused variants, the diffused variant will appear dimmer but have a wider viewing angle. These pack of 5mm LEDs have four pins - Cathode is the longest pin. Diodes have a minimum threshold voltage (or Vth, usually around 0.7V) that must be present between the anode and cathode in order for current to flow. What Id like to do is: Fade up to a set colour (cadmium orange rgb(255, 97, 3)) After a set period of 5sec, cross fade to an. Diodes are intended to conduct current from the anode to the cathode. Id like to use jled to control a 5mm RGB LED (common anode or cathode) due to the superior fading algorithm. The terminals of a diode are called the anode and the cathode a schematic symbol for a diode is shown in Fig. USB Scopes, Analyzers and Signal Generatorsĭiodes are two-terminal semiconductor devices that conduct current in only one direction. |
