Microsoft Roslyn vs. CodeDom
...t on the Roslyn team.
CodeDom is a precursor to Roslyn, but is only marginally related. Essentially, CodeDom is a simple and (somewhat) langage agnostic way to generate code that was added in .NET 1.0 to support designers (a la WinForms). Because CodeDom was an attempt at providing a unified model ...
Scheduling recurring task in Android
...leep as soon as your onReceive() method completes. If your alarm receiver called Context.startService(), it is possible that the phone will sleep before the requested service is launched. To prevent this, your BroadcastReceiver and Service will need to implement a separate wake lock policy to ensure...
kernel stack and user space stack
...memory (and hence a different value for the stackpointer register), and usually different memory access protections. I.e. when executing in user mode, kernel memory (part of which is the kernel stack) will not be accessible even if mapped. Vice versa, without explicitly being requested by the kernel...

How many concurrent requests does a single Flask process receive?
...tion and simply increasing the number of --workers, what you get is essentially a number of processes (managed by Gunicorn) that each behave like the app.run() development server. 4 workers == 4 concurrent requests. This is because Gunicorn uses its included sync worker type by default.
It is impo...
What is the most appropriate way to store user settings in Android application
...o there's some security there, but physical access to a phone could potentially allow access to the values.
If possible I'd consider modifying the server to use a negotiated token for providing access, something like OAuth. Alternatively you may need to construct some sort of cryptographic store, t...
What is the difference between Serializable and Externalizable in Java?
...ava.io.Serializable but with custom-written mechanisms to perform the marshalling and unmarshalling functions (you need to implement readExternal and writeExternal methods on your class). This gives you the means to get around the reflection performance bottleneck.
In recent versions of Java (1.3 ...
What's the role of GetHashCode in the IEqualityComparer in .NET?
...bjects - so the hash code is not necessarily unique.
A dictionary is a really cool data structure that trades a higher memory footprint in return for (more or less) constant costs for Add/Remove/Get operations. It is a poor choice for iterating over though. Internally, a dictionary contains an arr...
