As requested a little while ago, I will try to share my experience now more than one year after I asked the original question. We decided to use Windriver, but so far we have only written a driver for Windows CE 6.0, so I cannot comment on the cross-platform support. Using Windriver on Windows CE … Read more
Simply you can’t. C# produces intermediate language that is interpreted by a virtual machine (.NET). All these stuff runs in user mode and WDM drivers run in kernel mode. There is a DDK but it is not supported in VStudio either (but you can make a makefile project for compilation though). Driver development is complex, … Read more
I have started work on an IRDA driver stack over USB in user space. I am working out the basic plumbing but as far as I can see if I can create the equivalent user space driver to the linux kernel drivers such as the STIR4200 driver then I “ought” to then be able to … Read more

Firstly I should say that I don’t use MySQL but I do know about ODBC Drivers. In ODBC there are different APIs for unicode and ansi. The ansi APIs end in A and the unicode APIs end in W (e.g., SQLPrepareA and SQLPrepareW). The ansi APIs accept bytes/octets for character strings and hence can only … Read more
Take a look at the open-source WavTap, which is a simplified fork of the open-source SoundFlower virtual sound card driver. It is a .kext that I believe does substantially what you want. For reference, here is how some popular commercial closed-source options work: Rogue Amoeba’s Audio Hijack Pro -Captures system audio via code based off … Read more
The Short Answer At least one app is repeatedly querying WiFi for signal strength, and it’s chewing up a lot of battery life. The Longer Answer 1. What is RSSI RSSI stands for Received Signal Strength Indication. It is a measure of the power present in a wireless signal. RSSI queries are made each time … Read more
In my case the next dependency was missing: <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> In case of using IntelliJ and if you inherit from a <parent>, you can view your effective pom.xml by right clicking anywhere inside your pom.xml, then: and search for the mysql-connector-java artifact as mentioned.
assuming that a worker wants to send 4G of data to the driver, then having spark.driver.maxResultSize=1G, will cause the worker to send 4 messages (instead of 1 with unlimited spark.driver.maxResultSize). No. If estimated size of the data is larger than maxResultSize given job will be aborted. The goal here is to protect your application from … Read more
