These collisions may be between two particles, between a particle and the wall of the container, or between a particle and something else in the container. Since the particles in a gas are moving fast and randomly, collisions occur frequently. The smell of an air freshener can spread all around a room very quickly. This means that it does not take long for a gas to spread out to fill its entire container. The speeds of the particles vary but, on average, they move quicker than they do in liquids and solids.

If you just want to change the iOS app icon in an iOS device simulator, you can follow the below steps. I also opened up the Xcode assets to showcase all the different sizes that have been created. Change iOS App Icon In Xcode Simulator Steps. Now when we run the application on our simulator, we should see the app icon we defined. flutter pub run flutter_launcher_icons:main To generate the icons, we can run the following command. We could also specify a specific image for iOS or Android: flutter_icons: image_path_ios: 'images/icon-ios.png' image_path_android: 'images/icon-android.png' flutter_icons : android : true ios : true image_path : 'images/icon.png' Now after making the icon, we have to run the. Head back over to the pubspec.yml file and add the following configuration. After the installation of the required tools, we need an application icon. I made this basic image for my app icon just to demo how it will look. The real killer is that this isn’t a one-off job, you. The last icon set I created in Xcode needed 18 different individual icon sizes. Place this image in a folder called images at the root of your directory. Generating icons for your iOS project can be time consuming. However, for this demo, I'll use one generic image. Also, don't use alpha or transparency in this image (for iOS). Then we need to install this plugin by running: flutter pub get Adding our app icon įor our base icon to work, I would suggest having a logo that is 1024x1024px in size. There are other sizes to cater to, like Spotlight/Settings icons and iPad icons. The image resolution doesn't matter at all only the pixel dimensions matter. For the iPhone 4, save your 114x114 icon as Icon2x.png. dev_dependencies : flutter_launcher_icons : '^0.8.0' 4,729 6 50 100 Add a comment 6 Answers Sorted by: 53 For older devices, save your 57x57 icon as Icon.png. Adding the flutter_launcher_icons plugin įlutter is built in a way we can easily add plugins.įor this one, head over to your pubspec.yml file and add the following line to your dev_dependencies. Yet, we don't want to make all these images ourselves. The idea is that apps need many different sizes of App Icons for all kinds of devices and resolutions. Today we'll learn how to automatically generate App Icons for iOS and Android-based on one image source! While doing some research, I learned it's easy for Flutter as well!

Bob was replaced by her cousin Constantine "Vision" Walker, who recorded a few songs as a member of The Wailers during this period, with Rita providing harmonies. "Friends and Lovers", "One More Chance" and "That Ain't Right" (featuring harmony vocals by the Wailers), as well as a duet by Rita and Bunny Wailer, "Bless You" were issued years later on the Lovers and Friends album.Īfter those recordings for the Studio One (record label) coached by Bob, Rita married Bob Marley around February 1966, just before her husband moved to Wilmington, Delaware for a few months to make a living working at the Dupont Hotel there. The Soulettes released recordings including rocksteady tunes such as "Time for Everything", " Turn Turn Turn" (released in 1966, written by folk singer Pete Seeger) and "A Deh Pon Dem". She was raised in Trenchtown in Kingston, Jamaica. In her memoir No Woman No Cry: My Life with Bob Marley, she describes how she was raised by her Aunt Viola after her parents separated. Rita was born in Santiago de Cuba, to Leroy Anderson and Cynthia "Beda" Jarrett, her parents moved to Kingston, Jamaica, when she was three months old.

Just a nice girl who don’t take birth control. 45 ACP), and certainly isn’t close to what a well-designed rifle bullet can do, some of which have BCs of 0.83 or better. This isn’t particularly good (several semi-auto handgun cartridges offer bullets with higher BC, even the. The cartridge is certainly capable of being effective at further distances, but the question becomes, how effective can the shooter be at making those longer-range hits? The G1 ballistic coefficient (BC) of most 9mm bullets varies from around 0.13 for many 115-grain bullets to 0.17 for some 147-grainers (higher BC bullets generally “fly better”). The 9mm Parabellum cartridge was designed by its creator, Georg Luger, to be lethally effective out to 50 meters (164 feet). 22LR is greater than around 250 yards maximum. But almost nobody would claim that the “effective range” of. 22LR ammo published that the bullet was potentially lethal out to one mile, and tests have shown that to be the case. After all, we know that for many years, manufacturers of. Carbines and rifles can often produce even higher velocities.ĭiscussing the “effective range” of any cartridge is always a question of priorities and is somewhat subjective. If you choose to shoot +P or +P+ ammo through your gun, you assume the risks or at the very least, the increased recoil and wear to the gun. In +P and +P+ (higher pressure) loadings from boutique manufacturers such as Underwood Ammo and Buffalo Bore, you can potentially achieve speeds of around 1,400 fps in 115 grain, 1,300 fps in 124 grain, and 1,100 fps in 147 grain 9mm from standard-length handgun barrels. In standard, non-plus-P loads, commonly available 115-grain 9mm cartridges typically produce around 1,150-1,200 fps from 4” barrels, while 124-grain bullets are usually clocking around 1,100-1,150 fps (there are some aberrations but this is a pretty good generalization). Modern loadings can do a little better, but many “bulk” loads today produce similar numbers. The original 9mm Luger load from 1902 was an 8 gram bullet (approximately 124 grains) fired at a speed of 327 meters per second (1,073 feet per second) out of a 100mm-long barrel (a little less than 4 inches). > Restoring backups to a new device just got way easier thanks to Keep iTunes around for buying or playing media files, but when it comes to managing iOS devices and transferring media files, it doesn’t get much better than iMazing 2. There are plenty of smaller improvements too, like a new preferences tab for Devices, with options to prevent iTunes from performing automatic backups or launching after connecting a device. Although like iTunes, you won’t be able to downgrade to older iOS versions once Apple has stopped signing them. You can also do the same with a complete reinstall, even during a restore. Since devices are always connected to the utility over Wi-Fi, iMazing detects when the current version is out of date and offers to update with a click. (Signing in to install App Store updates is still required, however.) Similar conveniences extend to updating or reinstalling iOS itself. You’ll endure fewer annoying iOS Setup Assistant screens during a restore, since the software automatically takes care of many account login prompts for you. Restoring backups to a new device just got way easier thanks to iMazing’s one-click transfer wizard. Rather than having to connect a new device via Wi-Fi to activate and update to the latest version of iOS, iMazing seamlessly handles these tasks as part of its restore wizard. IMazing 2.2 makes other welcome improvements to the traditionally front-loaded restore process. It’s a more streamlined process that puts Apple’s cumbersome method to shame. Rather than restore from iTunes or a lengthy iCloud backup, you simply connect both devices, start the transfer, and sit back while the software does its thing. One of iMazing’s coolest features is the ability to copy content between devices, quite handy for upgrading to a new iPhone or iPad. IMazing can also access and export text messages, but only from an existing device backup. My personal pet peeve is how long the application takes to perform an initial scan of iCloud Photo Library thumbnails, although devices with fewer images won’t have this problem. As a result, iMazing occasionally feels slower to use than iTunes. Certain data types including Messages, call history, voicemail, Contacts, and Notes can only be accessed from a backup, rather than the device itself. There are other limitations to be aware of. Better yet, photos can now be transferred from computer to iOS via drag-and-drop, although albums created this way can’t be deleted from the Photos app and won’t be included in backups. In addition to managing apps, photos, music, videos, notes, call logs, and voice memos, iMazing 2.2 adds the ability to transfer ebooks and PDF documents to iBooks. IMazing allows iOS device backups to be saved anywhere, but only Mac or PC formatted volumes work for archives. (Archives work on Mac or PC-formatted volumes, not on network-attached storage devices.) J. Annoyed by how iTunes saves device backups on your internal drive? With iMazing, you can store these enormous files anywhere you’d like, and browse archives with Time Machine-style simplicity. iMazing also does many things Apple’s media player can only dream of, like exporting iMessage conversations. Think of iMazing as iTunes without media purchasing or playback, but a whole lot more versatile. Available for Mac or PC (the license can be used on either platform), iMazing doesn’t sync files in the traditional sense, but rather acts as a conduit for transferring files between desktop computers and iPhone, iPad, or iPod devices. IMazing ($40 for a single-user license multi-user licenses available) is an iOS device management utility designed as an alternative to iTunes. □ A brief recap on Foreign Keysįoreign key constraints are the standard measure to ensure referential integrity in relational databases. In this guide, we’ll walk through all options you have when configuring foreign key constraints, how you can detect the mode an existing foreign key constraint is set to, and how to model your data around these concepts.įor the remainder of the guide, we’ll walk over most parts of the foreign key creation grammar, so it might be helpful to keep the following in mind PostgreSQL offers a wide range of options for foreign keys, including marking foreign key constraints as deferrable in complex cases. Sometimes, rows referencing deleted or updated entities should stay around, sometimes, the deletion process should cascade and include all referencing rows, too. You might have experienced a scenario where a traditional foreign key constraint would be violated, for example, when creating circular references or having multiple entities depend on a resource where all rows are dropped at once.

Hey there □ I would like to quickly plug a product I am working on to eliminate blind spots before they become problems. Watts and his partner Mohammed were in an unmarked car with city plates, and Brian Bolton and Bobby Gonzales, two other members of the team, were in a CPD Tahoe. The girlfriend told them the following story: She and their baby were in the car with Monk, who was in the process of re-upping, distributing packages, and collecting money - so there was lots of dope and cash in the car. One day, as they drove past the apartment where Monk Fears and his girlfriend lived, they noticed his car was smashed up. Yet they continued - “two officers, one car, one radio” - to work the case. Exposed and isolated, now known as “IAD rats,” they knew better than anyone what Watts and Co. According to Spalding and Echeverria, the character of their jobs - the very air through which they moved - had fundamentally changed after they were outed by the head of internal affairs, Chief Juan Rivera. Operating largely on their own without meaningful support from either the FBI or CPD’s internal affairs division, Chicago police officers Shannon Spalding and Danny Echeverria carried on as best they could with their investigation into the far-flung criminal enterprise allegedly run by Sgt. Superintendent Garry McCarthy leaves a Chicago police station in the Englewood neighborhood following a press conference on May 6, 2013. Among the things known about McCarthy that might have been expected to stir anxieties were his strong identification with CompStat and his intention to move swiftly to make good on Emanuel’s campaign pledge to put an additional 1,000 officers on the street. This is especially true when the new superintendent comes from outside and is an unknown quantity. While the integrity of Mayor Daley’s Superintendent Jody Weis was never questioned, he had often seemed politically tone deaf and had proved unable to translate his outsider status into effective power within the department.Įmanuel’s choice - Garry McCarthy, the police director of Newark, New Jersey - was also an outsider, but he was described as “a cop’s cop.” McCarthy had earlier served under William Bratton in New York, where he built his reputation managing CompStat, the data-driven management tool the NYPD had developed for holding commanders accountable for crime in their districts.įor high-ranking police officials, transitions in department leadership are “times of upheaval,” as one put it to me. No Emanuel appointment was more closely watched than his choice of a new superintendent for the Chicago Police Department. Being mayor of Chicago, he insisted, was his dream job. His election drew national attention and insistent speculation that he saw the role of mayor as a stepping stone to the White House, something he repeatedly denied. What the police can do is take guns off the street.On February 22, 2011, Rahm Emanuel was elected mayor of Chicago, bringing to an end the 22-year reign of Mayor Daley the Second. “How do we resolve the root cause of violence and if that falls to police, you’re putting too high of a burden for police to resolve poverty and mental health challenges and drug addiction. He spoke of the city’s “whole-of-government approach,” which brings city and social services to communities, in addition to a heightened police presence. The superintendent touted recent strategic moves that include putting additional focus in struggling South and West side communities that has led to decreased homicides and shootings, as well as more recent resources placed on the Chicago Transit Authority to address an uptick in violent crime.īrown did try to temper expectations, pointing out that police respond to emergencies and not address basic social ills that aid crime. The crowds, besides the one incident where they were throwing objects at the police, were for the most part peaceful,” McDermott told reporters. “For the most part, there was no large fights that were breaking out. No injuries were reported, but the pineapple exploded when it hit an officer’s chest, police said. Brown and Chief of Patrol Brian McDermott did describe an incident where officers made mass arrests after a group of teens began throwing glass bottles - and a pineapple - at officers. On Monday, police made 13 arrests as thousands of people descended on North Avenue Beach and recovered 11 guns in what police called a mostly orderly day. Several people fight as a group of young people gather after seeing an internet meet-up flyer titled "North Ave Beach Takeover" on May 30, 2022, in Chicago.

There are often as many as three bottle mounts-two in the main triangle of the frame and one under the down tube. Places for fenders and racks are standard. Gravel bikes usually have plenty of them. That’s why they’ve drawn many solutions, e.g., from touring bikes. Gravel bikes have to adapt to various conditions and be as versatile as possible. The cyclocross bike is much more specialized and it works best on short, winding, muddy trails. Combined with long rear forks, which provide a larger wheelbase, gives us reliable, predictable steering and stability, even when loaded with heavy luggage.ĭue to these features, gravel bikes are great for adventures, when we often can't quite predict exactly what type of terrain we’ll encounter on the way or when we’re reckoning with the fact that we won't only be riding on tarmac. Thanks to this treatment, the bike copes well at high speeds on heavy terrain. What makes this type of two-wheeler stand out from the crowd? The taller head tube, reminiscent of those known from endurance road bikes, and slacker angles than cyclocross bikes, make gravel bikes comfortable on very long routes, and even suitable for ultra-marathons and spending several hours in the saddle.Īnother feature of the gravel bike, compared to road bikes or CXs, is the low bottom bracket. Imagine something between a cyclocross, a road bike, and an MTB.Ĭomfortable geometry for those long routes, maximum durability and functionality combined with stability, and even some damping capabilities, without substantial losses in speed, these are the features of a gravel bike. The easiest way to characterize this type of bike is probably by referring to categories we’re already familiar with. Another category slowly began to emerge.įrom the need to own a bike that would be suitable for tarmac, but also able to cope well on light terrain or simple singletracks, the gravel bike was created. Endurance road bikes for long-distance races (the so-called Audax) started to mutate and more and more "off-road" details started to appear on them. After all, they were created for fast muddy races with lots of sharp turns, not for multi-day adventures with luggage.Īs usual, people began to experiment, rebuilding their old road bikes, installing thicker tires, and changing the drivetrain. However, the geometry of these two-wheelers is not entirely suitable for longer trips. The first idea that springs to mind to tackle such terrain is a cyclocross bike. Long adventures, intended to be roadlike by nature, usually result in us having to deal with short sections of mountain bike riding at the same time. Terrain like this is too tough for a road bike, but it’s also easy enough to be ridden on that an MTB is an overkill, and because of that we can find a much faster, more practical solution. There was a particularly strong niche for it in the USA, a country full of long forest, gravel roads. It originated from a specific need and, contrary to popular belief, it’s not an artificially driven trend. Genesis - where did the gravel bike come from? Sounds too good to be true, right? Of course, this isn't entirely the case, but you could certainly chance saying that a gravel bike is one of the most versatile types of bikes out there. So basically, it’s a bike for everything. At the same time, when the mud, forest paths, and gravel appear on the horizon, you won't have to get off it and wring your hands. It's a bike that isn’t afraid of a quick coffee ride and a bike that’ll keep you up to speed with the rest of the group on. A gravel bike is an MTB for road cyclists and a road bike for mountain bikers. Imagine the Frankenstein among two-wheelers. What’s this type of bike, anyway? And why has the whole cycling world gone crazy about it over the last few years? |
