Fog is especially prevalent in some regions, including much of the Southeast, northern New England, the Pacific Northwest and the Central Valley of California, and it forms most often in winter. Deadly multicar crashes generally occur when cars and trucks traveling at interstate speed drive into what is essentially a low-lying cloud and quickly lose visibility. Drivers may not see the slowed cars ahead until it is too late, with one vehicle crashing into the next, including huge tractor-trailers.
Eleven people died in a pileup in January near Gainesville, Fla. In November , a chain-reaction crash of vehicles in fog near Fresno, Calif. On Jan. Lighting and safety experts caution that stand-alone front fog lights, which are usually set into the bumper close to the road, may be inadequate to prevent such horrific highway-speed crashes. But they can help drivers see road markings in fog at low speeds, perhaps keeping the car from hitting a tree or running into a ditch. High-beam headlights, designed to send light into the distance, are especially ineffective at penetrating the fog, as they reflect off the moisture in the air.
But even low beams throw enough light into the fog curtain that the effect can be blinding rather than illuminating. Fog lamps are intended to provide an adjunct to the low beams. Because fog hovers close to the ground, the lamps are designed to shine down, illuminating the road beneath the fog. The top of the beam is cut off sharply so the light does not shine into the fog and reflect off it. Even before automakers began offering high-tech headlights, many vehicles on American roads did not have front fog lamps. Though common on cars from European manufacturers and on luxury models from American and Japanese companies, they tended to be options on mainstream models, sometimes included on premium trim lines or in extra-cost feature packages.
Aside from the fog lights in the front, which can help the driver to navigate, rear fog lamps — which look like an extra-bright taillamp on just one side — make cars more visible in bad weather to following drivers. Rear fog lamps are required in Europe but not in the United States, though most European manufacturers include them on cars sold in the United States. And drivers sometimes leave the rear units on even when the skies are clear, just as they do with the front units, which other motorists can find distracting.
After bundling your app into Electron, you will want to rebrand Electron before distributing it to users. You can rename electron.

You can rename Electron. You can also rename the helper app to avoid showing Electron Helper in the Activity Monitor, but make sure you have renamed the helper app's executable file's name. It is also possible to rebrand Electron by changing the product name and building it from source.
Creating a custom fork of Electron is almost certainly not something you will need to do in order to build your app, even for "Production Level" applications. Using a tool such as electron-packager or electron-forge will allow you to "Rebrand" Electron without having to do these steps. As maintainers of Electron, we very much would like to make your scenario work, so please try as hard as you can to get your changes into the official version of Electron, it will be much much easier on you, and we appreciate your help. Install Surf , via npm: npm install -g surf-build latest.
To mitigate issues around long path names on Windows, slightly speed up require and conceal your source code from cursory inspection, you can choose to package your app into an asar archive with little changes to your source code. Most users will get this feature for free, since it's supported out of the box by electron-packager , electron-forge , and electron-builder. If you are not using any of these tools, read on.
An asar archive is a simple tar-like format that concatenates files into a single file. Electron can read arbitrary files from it without unpacking the whole file. Both APIs support reading files from asar archives. In a web page, files in an archive can be requested with the file: protocol. Like the Node API, asar archives are treated as directories. For some cases like verifying the asar archive's checksum, we need to read the content of an asar archive as a file. For this purpose you can use the built-in original-fs module which provides original fs APIs without asar support:.
You can also set process. Even though we tried hard to make asar archives in the Node API work like directories as much as possible, there are still limitations due to the low-level nature of the Node API. The archives can not be modified so all Node APIs that can modify files will not work with asar archives. Though asar archives are treated as directories, there are no actual directories in the filesystem, so you can never set the working directory to directories in asar archives. Passing them as the cwd option of some APIs will also cause errors. Most fs APIs can read a file or get a file's information from asar archives without unpacking, but for some APIs that rely on passing the real file path to underlying system calls, Electron will extract the needed file into a temporary file and pass the path of the temporary file to the APIs to make them work.
This adds a little overhead for those APIs. The Stats object returned by fs. So you should not trust the Stats object except for getting file size and checking file type. This is because exec and spawn accept command instead of file as input, and command s are executed under shell. There is no reliable way to determine whether a command uses a file in asar archive, and even if we do, we can not be sure whether we can replace the path in command without side effects.
As stated above, some Node APIs will unpack the file to the filesystem when called. Apart from the performance issues, various anti-virus scanners might be triggered by this behavior. As a workaround, you can leave various files unpacked using the --unpack option. In the following example, shared libraries of native Node. After running the command, you will notice that a folder named app. It contains the unpacked files and should be shipped together with the app.
On macOS, the autoUpdater module is built upon Squirrel. Mac , meaning you don't need any special setup to make it work. For server-side requirements, you can read Server Support.
Note: Your application must be signed for automatic updates on macOS. This is a requirement of Squirrel.

On Windows, you have to install your app into a user's machine before you can use the autoUpdater , so it is recommended that you use the electron-winstaller , electron-forge or the grunt-electron-installer package to generate a Windows installer. When using electron-winstaller or electron-forge make sure you do not try to update your app the first time it runs Also see this issue for more info. It's also recommended to use electron-squirrel-startup to get desktop shortcuts for your app.
The installer generated with Squirrel will create a shortcut icon with an Application User Model ID in the format of com. Slack and com. You have to use the same ID for your app with app. Unlike Squirrel. Mac, Windows can host updates on S3 or any other static file host. You can read the documents of Squirrel.
Windows to get more details about how Squirrel. Windows works. Note: It is not strictly necessary to handle this event.
A successfully downloaded update will still be applied the next time the application starts. When this API is called, the before-quit event is not emitted before all windows are closed. As a result you should listen to this event if you wish to perform actions before the windows are closed while a process is quitting, as well as listening to before-quit.
