Why does a Swing GUI freeze or lock up?

Class IAQ
What's important is that a single thread is used for all components. Thus, you might fire up multiple components, but a single thread is used to listen for all events. This means if any one component keeps this one thread busy, the other components will not respond to the user. Why is it done this way? See the Java website for a detailed explanation, but briefly, it's because most applications can be written with the one-thread model and it's easy to write with.

Why does GFS lock up/freeze when a node gets fenced?

Cluster Project FAQ
When a node fails, cman detects the missing heartbeat and begins the process of fencing the node. The cman and lock manager (e.g. lock_dlm) prevent any new locks from being acquired until the failed node is successfully fenced. That has to be done to ensure the integrity of the file system, in case the failed node wants to write to the file system after the failure is detected by the other nodes (and therefore out of communication with the rest of the cluster).

How does the lake freeze?

Portland Water District - Frequently Asked Questions
In the fall, when water cools, it becomes more dense and sinks to the bottom of the lake. Water is "heaviest" at 39 degrees F. As winter nights cool the water from 39 degrees down to 32 degrees, it expands and freezes! Expanded, frozen water (ice) is less dense, and lighter, so it floats! The fact that ice forms from the top down is lucky for fish and lucky for us - the ice acts as an insulator; and the heavier water at the bottom remains in its liquid form. See similar questions...

How does a state security freeze differ from a federal fraud alert?

Frequently asked questions about security freeze
A security freeze is a mechanism to prevent new account identity theft. Only a security freeze allows the consumer to limit access to his or her consumer reporting file. The federal Fair Credit Reporting Act creates two types of fraud alerts, but the only type available to consumers who have not yet been victims of identity theft, called the initial fraud alert, expires after 90 days unless renewed. The very short time period makes this a poor tool for ID theft prevention. See similar questions...

How does GUI ScreenIO compare in usability to other COBOL GUI tools?

GUI ScreenIO License
GUI ScreenIO is the easiest to use - by far. Try it and see for yourself.

These are a snap with GUI ScreenIO, but can be a real pain if you use most other products. Take a good look and compare us. When we set out to design GUI ScreenIO, we resolved to make ease of use as important as the features. See similar questions...
