Utilizing a combination of transmission methods, lethal and nonlethal symptoms, and crucial resistance traits, your goal is to be the one that leaves no survivors. In Plague Inc: Evolved, your goal is to take a single variety of pathogen infecting a Patient Zero and build them up from a localized infection to a world-threatening plague. Low risk, low cost, and a lot of freedom to experiment. From its origins as a simple mobile game, now available under Early Access on Steam, the one-man production known as Ndemic Creations has brought the science of epidemiology to the hands of thousands of casual gamers, and just like the diseases the game portrays, its appeal can be rather contagious! But has its infectious spread been the result of a finely-crafted genome, or simply a well-timed lucky mutation? Put on your breathing masks and follow me into the autopsy room…īacteria is the easiest pathogen to work with. This is the reality of Plague Inc: Evolved, an epidemic simulator and strategy game where the goal is to evolve your virus into the germ that can wipe out the human race. The symptoms awaken as the announcement flashes before your eyes, and the list is growing fatal, ending with a coma, and then… You’re not the person in this scenario, though…you’re the plague itself! Imagine the day when you turn on the television and the news is reporting a nationwide pandemic, claiming a product that you use every day to be contaminated by a horrifying pathogen that was incubated in India and resistant to every drug you and your health insurance can afford.

Mountaineers often climb frozen waterfalls as a challenging test of their skill. For at least part of the year, the waterfall freezes. Virgin Falls is a striking fan waterfall on Tofino Creek, on Vancouver Island, British Columbia, Canada.įrozen waterfalls are just what they sound like. Water spreads out horizontally as it descends. Three Chute Falls is named for the three "chutes" through which the Tenaya Creek falls in Yosemite National Park, California, U.S.įan waterfalls are named for their shape. Among the widest and wildest of cataracts are the thundering waters of the Iguazu River on the border between Brazil and Argentina.Ī chute is a waterfall in which the stream passage is very narrow, forcing water through at unusually high pressure. The waterfall is safe enough for children to play in the water.Ī cataract is a powerful, even dangerous, waterfall. Monkey Falls, in the Indira Gandhi Wildlife Sanctuary and National Park in Tamil Nadu, India, is a gently sloping cascade. Niagara Falls, in the United States and Canada, is a block waterfall on the Niagara River.Ī cascade is a waterfall that descends over a series of rock steps. Most waterfalls fit more than one category.Ī block waterfall descends from a wide stream. A waterfall's type is simply the way the descends. One of the most popular, if least scientific, ways to classify waterfalls is by type. The water is turned to mist before it reaches the small tributary below. The fall is so long, and so steep, that air pressure is stronger often than the water pressure of the falls. The water, from the Gauja River, often does not reach the bottom. Angel Falls, the world’s tallest waterfall, plummets 979 meters (3,212 feet) into a remote canyon in a rain forest in Venezuela. Waterfalls are also classified by height. The width of the Khone Phapheng Falls is about 10,783 meters (35,376 feet). At the Khone Phapheng Falls, the Mekong River flows through a succession of relatively shallow rapids. One of the widest waterfalls is Khone Phapheng Falls, Laos. The estimated volume of water discharged from Inga Falls is 25,768 cubic meters per second (910,000 cubic feet per second).Īnother popular way of classifying waterfalls is by width. A Class 10 waterfall using this scale is Inga Falls, Democratic Republic of Congo, where the Congo River twists in a series of rapids. Some scientists classify waterfalls based on the average volume of water in the waterfall. There is not a standard way to classify waterfalls. An earthquake, landslide, glacier, or volcano may also disrupt stream beds and help create waterfalls. A waterfall may form across a fault, or crack in the Earth’s surface. The waterfall erosion process starts again, breaking down the boulders of the former outcropping.Įrosion is just one process that can form waterfalls. This causes the waterfall to "recede" many meters upstream. The resulting erosion at the base of a waterfall can be very dramatic, and cause the waterfall to " recede." The area behind the waterfall is worn away, creating a hollow, cave-like structure called a "rock shelter." Eventually, the rocky ledge (called the outcropping) may tumble down, sending boulders into the stream bed and plunge pool below. The crashing flow of the water may also create powerful whirlpools that erode the rock of the plunge pool beneath them. Rushing water and sediment topple over the waterfall, eroding the plunge pool at the base. The movement of water at the top of a waterfall can erode rocks to be very flat and smooth. Waterfalls develop as these granite formations form cliffs and ledges.Ī stream's velocity increases as it nears a waterfall, increasing the amount of erosion taking place. Eventually, the stream's channel cuts so deep into the stream bed that only a harder rock, such as granite, remains. Sediment can erode stream beds made of soft rock, such as sandstone or limestone. The sediment can be microscopic silt, pebbles, or even boulders. Many waterfalls in an area help geologists and hydrologists determine a region's fall line and underlying rock structure.Īs a stream flows, it carries sediment. In both cases, the soft rock erodes, leaving a hard ledge over which the stream falls.Ī fall line is the imaginary line along which parallel rivers plunge as they flow from uplands to lowlands. This happens both laterally (as a stream flows across the earth) and vertically (as the stream drops in a waterfall). Often, waterfalls form as streams flow from soft rock to hard rock. Waterfalls themselves also contribute to erosion. The process of erosion, the wearing away of earth, plays an important part in the formation of waterfalls. A waterfall is a river or other body of water's steep fall over a rocky ledge into a plunge pool below. In the wake of such a nuclear disaster, protocol called for the evacuation of nearby communities, including the city of Pripyat. And we didn't know then that they were just the first ones. We learned that another one was left under the debris - Valera Khodemchuk. Lyudmilla Ignatenko, the wife of one of the firemen, recalled:Īt 10 in the morning, the cameraman Shishenok died. Radiation continued to leak from the core and spread to the surrounding area via the wind. More than 100 people received acute radiation poisoning, and dozens died within months. Meanwhile, massive amounts of radiation poured out of the exploded reactor. Employees kept working, and firefighters arrived to quell the blaze without radiation-protective gear. Fires immediately broke out, and two men died in the chaos - one of whom was buried in the debris and remains there to this day.ĭespite the violence of the initial incident, the engineer on staff erroneously believed the reactor's core was undamaged and unexposed. 4 reactor at the plant exploded, and a meltdown occurred. The original explosions that rocked the nuclear power plant at Chernobyl occurred at around 1:30 in the morning on April 26, 1986. Those who worked at the nuclear plant or lived in the surrounding areas tell haunting tales about what it was like in the immediate aftermath of the Chernobyl disaster. Many of them shared their recollections in the book Voices From Chernobyl: The Oral History of a Nuclear Disaster by Nobel Prize-winning author Svetlana Alexievich. Decades after the incident, although the area has come back to life in some ways, harmful effects persist. But for those closest to the danger, the news came far too late. Immediately following the disaster, the Soviet government downplayed the dangers of the large amount of radiation the explosion and subsequent fire released, which led to widespread misinformation - or no information at all. The rest of the world soon discovered the severity of the disaster at Chernobyl. The effects of the Chernobyl disaster reverberated worldwide, with long-term repercussions for wildlife, humans, and the environment. At the time, the people living near Chernobyl in what is now Ukraine, including first responders to the scene, didn't know they were experiencing a life-changing event. 4 reactor exploded at the Chernobyl nuclear power plant on April 26, 1986, a colossal meltdown began. On the other hand, if you're looking for a great app to edit your photos, Pixelmator 2.6 is definitely worth checking out. With its intuitive interface, users can quickly customize their photos and get the professional-level results they desire. The brushes are limited and the user interface makes it feel like there's a barrier between you and the artwork you want to create. Overall, PixelMator is a great way for any user to edit and enhance their photos on their devices. However, if you're looking for an app for digital illustration, Pixelmator still has a lot of growing to do. When it comes to touching up and editing photos, it's easy to use and has a lot of nice features. Cmd+Z on the Magic Keyboard can be used as a shortcut to undo, but if you're drawing, you may not want to have the keyboard attached. It includes an extensive collection of cutting-edge color adjustments, automatic selections powered by AI, powerful batch editing features, Clone and Repair tools for removing unwanted objects, and much more. It doesn't seem like a big deal initially, but when you're constantly testing and tweaking paintbrushes, having to tap an Undo button in the upper-left corner grows old very quickly. Photomator is a photo editing powerhouse, offering incredible tools for enhancing, retouching, and managing your photos. This has become standard in most drawing applications and is even integrated into Pixelmator Photo, but has oddly been omitted from Pixelmator 2.6. The Pixelmator team has updated its namesake app for iPhone and iPad to version 2.7. Designed exclusively for iOS and iPadOS, Pixelmator takes full advantage of the latest iOS and iPadOS 16 features and. One major missing feature is the ability to two-finger tap to undo. Pixelmator is a powerful, full-featured, layer-based image editor that lets you add shapes, images, and text to create beautiful image compositions, touch up and enhance images, sketch, and paint on iPad and iPhone alike. A new refreshed design incorporates the 'fresh and modern look' of iOS 15 and iPadOS 15 alongside new features.

You only need to download "Windows Executable" zip file from here. However, because GUI is developed in Win7 environment, I can't guarantee backward compatibility. Obviously, such data won't be displayed correctly in GUI Metadata panel, because here, UTF-8 encoded data is expected.ĮxiftoolGUI should run on WinXP up to Win7-64bit. If really needed, then you can still enter "old" ANSI (non-UTF-8) encoded data by using -L option in ExifTool direct mode, i.e: Anyway, all this concerns only "foreign" characters: if you allready used "standard" alphabet (ASCII) characters only, then you won't notice any difference. change/overwrite such tag content (which becomes UTF-8 encoded).īut be aware, that UTF-8 encoded Exif content might not be properly recognized by some other software. If you notice this, then this means, metadata content isn't UTF-8 encoded. It can/will happen, that GUI will show some "weird" characters where country specific characters should appear -if at all, this can/will happen for existing Exif metadata content (i.e: Exif:Artist). However, Metadata Working Group (MWG) organisation recommends using UTF-8 in Exif as well. Right now, the only exception is Exif, which oficially doesn't support UTF-8 yet. For Iptc metadata, UTF-8 charset has also become officially recommended. It's about displaying "foreign", country specific characters:įor Xmp metadata, UTF-8 charset is used as default charset since beginning, so nothing changes here. edited metadata values will be automatically saved in UTF-8 format.characters inside metadata will be shown properly, if metadata content is UTF-8 encoded.-batch capability (where appropriate), means: you can select multiple files and modify them at once.īasic idea behind GUI is, to keep it simple! Thus, only those options are implemented, which I believe, are essential for majority of users.įor ALL metadata, UTF-8 character set encoding/decoding is used.-ability to edit most frequently used metadata tags,.-view all metadata that ExifTool recognizes,.When making ExifToolGUI, the main goal was: There are already some GUI's that make use of ExifTool, but some of them are not flexible enough (for my needs) and/or have somehow limited use. So, I've decided to make some simple ExifTool GUI for my private use. Such approach gives ExifTool great flexibility, but is somehow difficult to use -especially for those, who don't use ExifTool regulary. That means, there's no Graphic User Interface (GUI), so all work must be done by typing commands inside "Command Prompt" window. The only downside for many potential users is the fact, that ExifTool is a "command-line" utility. -it is very secure to use, is regulary updated and has the best possible support.-it allows to edit almost any metadata tag,.-it shows more metadata tags than any other tool,.In my opinion, ExifTool by Phil Harvey, is the best I've found so far. There are many tools for viewing/editing metadata inside image files. Exporting 100 photos took not quite 30 seconds longer with JPEGmini on compared to those same images with JPEG mini off. The only slight blip in my workflow is that exporting with JPEGmini enabled takes slightly longer than without. A toggle would have been easier for the occasions when you don’t want to downsize, but it’s still quick to add and remove JPEGmini to your workflow as needed. If you want to export original JPEGs without the JPEGmini reduction, you have to go back to the Post-Process Actions, click the plug-in, and hit remove. The window simply shows how much space you saved the last time. If the tab is there, the plug-in is active. There are no tools to check or anything inside the JPEGmini tab. Then you’ll see a JPEGmini option in the export workflow tabs. Then, in the export window on the left-hand column, locate the JPEGmini in the Post-Process Actions, and hit insert. Select a photo or photos to exports and hit export, just like you usually would. The next step is to add JPEGmini to the export workflow. Adding the plug-in is fairly simple, following the instructions that accompany the download. Once the plug-in file is downloaded, new users will head into Lightroom’s Plug-In Manager and add the file and activation code. For photographers that already use Lightroom - like me - it fits in seamlessly with an existing workflow. Once installed, there are very few extra steps to using the plug-in. While JPEGmini Pro is a stand-alone desktop app, the suite option includes a Lightroom plug-in. The bottom line? If you are at the mercy of slow internet speeds, own a website, or need to free up hard drive space but can’t even fathom deleting old archives, the JPEG Mini Lightroom plug-in is a worthwhile investment. (There’s also a JPEGmini Capture One Plug-in, which we use to decrease page load times here at The Phoblographer). The JPEG Mini Lightroom Plug-in is a set-and-forget way to resize files without interrupting my current workflow. I’ve used the stand-alone version of JPEGmini Pro before, which resizes images with very little loss of quality. I just delivered more than 900 full-resolution images working off nothing but a smartphone hotspot and an international plan that drops to 3G speeds after the first 2 GB - thanks to JPEGmini. That’s where the JPEGmini Lightroom Plug-in comes in. The decision over whether to upload high-resolution files to deliver to clients and to resize files in a way that, well, actually gets to its destination is the metaphorical rock and a hard place. And when I travel, I’m controlled by a Wi-Fi hotspot that quits working under heavy cloud cover. I live in a rural area with mediocre internet - and that’s being generous.
These are described as profiles of SVG 1.1. SVG Tiny and SVG Basic (the Mobile SVG Profiles) became W3C Recommendations on 14 January 2003.Apart from this, there is very little difference between SVG 1.1 and SVG 1.0. The SVG 1.1 specification is modularized in order to allow subsets to be defined as profiles. SVG 1.1 became a W3C Recommendation on 14 January 2003.SVG 1.0 became a W3C Recommendation on 4 September 2001.SVG 2 incorporates several new features in addition to those of SVG 1.1 and SVG Tiny 1.2. Scalable Vector Graphics 2 became a W3C Candidate Recommendation on 15 September 2016. The SVG specification was updated to version 1.1 in 2011. The working group was chaired at the time by Chris Lilley of the W3C. WebCGM, from Boeing, PTC, InterCAP Graphics Systems, Inso Corporation, CCLRC, and Xerox.Hyper Graphics Markup Language (HGML), by Orange UK and PRP.VML, by Autodesk, Hewlett-Packard, Macromedia, Microsoft, and Vision.PGML, from Adobe Systems, IBM, Netscape and Sun Microsystems.SVG was developed by the W3C SVG Working Group starting in 1998, after six competing vector graphics submissions were received that year: The early SVG Working Group decided not to develop any of the commercial submissions, but to create a new markup language that was informed by but not really based on any of them. SVG has been in development within the World Wide Web Consortium (W3C) since 1999 after six competing proposals for vector graphics languages had been submitted to the consortium during 1998 (see below). In web-based applications, Inline SVG allows embedding SVG content within HTML documents.ĭespite its benefits, SVG can pose security risks if used for images, as it can host scripts or CSS, potentially leading to cross-site scripting attacks or other vulnerabilities. SVG can be produced using vector graphics editors and rendered into raster formats. Mobile support for SVG exists in various forms, with different devices and browsers supporting SVG Tiny 1.1 or 1.2. Native browser support offers various advantages, such as not requiring plugins, allowing SVG to be mixed with other content, and improving rendering and scripting reliability. However, as of 2011, all major desktop browsers began to support SVG. The XML text files can be created and edited with text editors or vector graphics editors, and are rendered by the most-used web browsers.Įarly adoption was limited due to lack of support in older versions of Internet Explorer. SVG images can thus be scaled in size without loss of quality, and SVG files can be searched, indexed, scripted, and compressed. SVG images are defined in a vector graphics format and stored in XML text files. The SVG specification is an open standard developed by the World Wide Web Consortium since 1999. This package is officially published, maintained and supported by Boxy SVG developer.SVG ( Scalable Vector Graphics) is an XML-based vector image format for defining two-dimensional graphics, having support for interactivity and animation.
This diagram will show you how to connect everything if you’re using a breadboard: A 10K Ohm resistor and a 10 μF capacitor in series between pin 7 and ground to decouple the audio input signal.A 0.1 μF capacitor between pins 4 and 6, for additional decoupling of the power supply to the chip.The 100 μF capacitor will filter low frequency noise while the 0.1 μF capacitor will filter high frequency noise. 100 μF and 0.1 μF capacitors between the positive and negative power rails to decouple the power supply.A 470 pF capacitor between the positive input signal and ground, which filters radio interference picked up by the audio input wires.Several things in this circuit make it sound better: If you don’t have a particular value, try substituting something close and it will probably work. Note: Most of the component values in this circuit aren’t critical. Now that you’ve seen the bare minimum of what it takes to make an audio amplifier with the LM386, lets build a higher fidelity version with an adjustable gain control. We’ll fix that in the next circuit by adding decoupling capacitors and a couple RC filters. Connecting it like this should sound better than the first circuit, but you”ll probably still notice some noise, static and popping. This will reduce the distance the input ground flows through the output ground. For example, you can connect the grounds for the power supply, input, and output directly to the ground pin (pin 4) of the LM386 like this: Make it a goal to keep the input ground separate from other ground paths as much as possible. The audio input ground is sensitive to any interference and any noise picked up will get amplified through the amplifier. The output ground is “noisy” and will cause distortion in the input signal if it’s wired this way. In the wiring diagram above, the audio input ground flows through the same path as the audio output ground. Here’s how to wire it if you’re using a breadboard: That way you can compare it to the better sounding one we’ll build later on. Now that we have a little background information on the LM386, let’s start by building a bare bones LM386 amplifier with the minimum amount of components needed to make it work. The gain can be changed to any value between 20 and 200 by placing a resistor (or potentiometer) in series with the capacitor. With the 10 μF capacitor, the gain will be set to 200. Without a capacitor between pins 1 and 8, the gain will be set to 20. Gain control can be achieved by connecting a 10 μF capacitor between pins 1 and 8. If your gain is set to 200, the range of volume is 0 to 200. For example, if your gain is set to 20, the range of volume is 0 to 20. Gain sets the range of possible volume levels. Volume lets you adjust the sound level within the range of amplification set by the gain. So what’s the difference then? Gain is the amplification of the input potential and is a characteristic of the amplifier. Gain vs VolumeĪfter you build this amp and play with the volume and gain controls, you’ll notice that both appear to raise or lower the intensity of sound coming out of the speaker. That amplification is what’s known as the voltage gain. In an amplifier circuit, the LM386 takes an audio input signal and increases its potential anywhere from 20 to 200 times. They take an input potential (voltage) and produce an output potential that’s tens, hundreds, or thousands of times the magnitude of the input potential. Operational amplifiers have a basic task. The LM386 is a type of operational amplifier (Op-Amp). The pinout is shown in the diagram below:ĭownload the datasheet for more information about the output power, distortion characteristics, and minimum/maximum ratings: I used a 9V battery for the power supply and it works great, but you can go down to 4V or up to 12V. The datasheet has graphs that will tell you. The actual output power you get will depend on your supply voltage and speaker impedance. There are three varieties of the LM386, each with different output power ratings: The chip has options for gain control and bass boost, and it can also be turned into an oscillator capable of outputting sine waves or square waves. Only a couple resistors and capacitors are needed to make a working audio amplifier. BONUS: Download my parts list for the LM386 amplifier with bass boost circuit to see which components to use for good sound quality. |
