They will receive the SIGTTOU signal to ask them to temporarily stop listening to the ports so … Read more
What Eric takes the long way to point you towards but doesn’t actually state is that you need to authorize the source as the amazon-elb/amazon-elb-sg. If you’re doing this through the AWS Management Console it will actually auto-complete when you start typing it into the source field. I operate several ELB configurations and they all … Read more
Before you make a decision based on scalability, you might want to read through these two pages and decide how much you value your sanity: PostgreSQL gotchas MySQL gotchas
The Compatibility tab is hidden for system files, so to replicate the functionality of the “Disable display scaling on high DPI settings” checkbox you would add the following to the registry: Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers] “C:\\Windows\\System32\\mmc.exe”=”~ HIGHDPIAWARE” This has the added benefit of making all MMC snap-ins like Group Policy Editor also … Read more
To expand on Karan’s answer: As a general rule you won’t see any difference if you’re scaling your image down, but you will if you’re scaling it up. Passing filter = false will result in a blocky, pixellated image. Passing filter = true will give you smoother edges. However, as EIYeante pointed out in the … Read more
Let’s say you want to scale a range [min,max] to [a,b]. You’re looking for a (continuous) function that satisfies f(min) = a f(max) = b In your case, a would be 1 and b would be 30, but let’s start with something simpler and try to map [min,max] into the range [0,1]. Putting min into … Read more
You’ll have to convert it from dps to pixels using the display scale factor. final float scale = getContext().getResources().getDisplayMetrics().density; int pixels = (int) (dps * scale + 0.5f);
To specify the coordinates within the SVG image independently of the scaled size of the image, use the viewBox attribute on the SVG element to define what the bounding box of the image is in the coordinate system of the image, and use the width and height attributes to define what the width or height … Read more
70 requests per second works out to an hourly rate of 252,000 page renders / hour. If you assume that the average browsing session for your site is 10 pages deep, then you can support 25,000 uniques / hour. You should probably check these numbers against your expected visitor count, which should be available from … Read more
I finally found the setting that was really limiting the number of connections: net.ipv4.netfilter.ip_conntrack_max. This was set to 11,776 and whatever I set it to is the number of requests I can serve in my test before having to wait tcp_fin_timeout seconds for more connections to become available. The conntrack table is what the kernel … Read more
