Notably, FreeSync over HDMI is the feature that stands out, however, until just recently, the screen tearing-reduction and stuttering-reduction components were only available through DisplayPort. Can samsung cf monitor used for mac?.

Are you a Linux user who switched to Mac when you saw that Docker is now available as a native Mac app? Have you heard how great Docker is and want to give it a? Did you think that you could just take your Docker Compose file, launch your project, and have everything work out for you?

Best wireless router 2013 for mac. Well you were right. Docker for Mac is a pretty smart invention. It gives you the whole Docker API available from the terminal, even though Docker itself wasn’t created to work on Macs. To make all this possible, a light Alpine Linux image is fired up underneath with xhyve MacOS native virtualization. Because of this, you need to allocate CPU cores and RAM for the VM.

Things won’t be as close to bare metal as they are in Linux. If you are – for example – a Java developer who uses Docker to run compiled JAR, you may even not notice the difference. At least, as long as you don’t try to do any heavy database work. Docker for Mac and Full Sync on Flush Issue First, let’s look at MacOS: “For applications that require tighter guarantees about the integrity of their data, Mac OS X provides the F_FULLFSYNC fcntl. The F_FULLFSYNC fcntl asks the drive to flush all buffered data to permanent storage. Applications, such as databases, that require a strict ordering of writes should use F_FULLFSYNC to ensure that their data is written in the order they expect.” In short, to keep our data safe, every change made in the database needs to be stored on disk in an exact order.

This will guarantee that during power loss or any unexpected event your data will be safe. Actually, this makes sense — if you decide to setup a database inside Docker for Mac on a production environment In most cases, though, you’ll be using your machine for dev purposes where you don’t care to recreate the database from fixtures. If you have a Macbook, even power loss isn’t a threat. In this case, you may decide to disable this. While reading about Docker issues on GitHub, I found a solution provided. Things will get a lot faster when you type those few lines into your terminal: $ cd ~/Library/Containers/com.docker.docker/Data/database/ $ git reset --hard HEAD is now at cafabd0 Docker started $ cat com.docker.driver.amd64-linux/disk/full-sync-on-flush true $ echo false > com.docker.driver.amd64-linux/disk/full-sync-on-flush $ git add com.docker.driver.amd64-linux/disk/full-sync-on-flush $ git commit -s -m 'Disable flushing' [master dc32fcc] Disable flushing 1 file changed, 1 insertion(+), 1 deletion(-) Actually, someone even placed to make things easier.

Does It Really Work? I created a to check this. This test uses a standard Docker MySQL image without tweaks, and an image with sysbench installed. In my test case, I decided to use one thread (I only allocated one core for Docker on my Macbook) and a table with 10,000 rows. I ran it twice: once with flushing enabled (default), and once with flushing disabled.
