Five simple database design tips
A flawed database can affect all areas of your application, so getting the design right is of paramount importance. Check out Builder's five simple design tips, and share some of your own. If an enterprise’s data is its lifeblood, then the database design can be the most important part of an application. I’ll get the show started by listing my five favorite tips and giving a brief explanation of the rationale behind each one. #1: Use meaningful field namesI once worked on a project I inherited from another programmer who liked to name fields using the name of the onscreen control that displayed the data from that field. Unless you are using a system that restricts you to short field names, make them as descriptive as possible—within reason, of course. #2: Do your homeworkNot only should you research your business needs when designing a new database, you should check out the existing system, as well. Restrict the user from editing the field after the record’s creation.

Audit and document Security User Rights Assignment using C# | Network Audit and Documentation, CENTREL Solutions Blog
For more information on the Windows Server documentation abilities of XIA Configuration please see the following We've recently been asked about the auditing of User Rights Assignment as seen in the Local Group Policy Editor. Having looked into this issue it is apparent that this cannot be done with any high level API such as WMI and requires the use of P/Invoke and the Win32 method LsaEnumerateAccountsWithUserRight. I've seen many posts on the Internet on the topic but I haven't seen a simplified example of this in use so have writen a quick C# sample application to enumerate the various rights and privileges and display the users assigned to that right in a grouped listview as per the screenshot below. This can be downloaded from our web site in Visual Studio 2010 The sample supports the following Document and Audit User Rights Assignment with XIA Configu

RS-232 Communications (software) Now that we understand the hardware part of the picture, let's dive right into the software part. We'll take a look at each part of the puzzle by defining a few of the common terms. ASCII is a human-readable to computer-readable translation code. The picture below shows how data leaves the serial port for the character "E" (45h 100 0101b) and Even parity. Another important thing that is sometimes used is called software handshaking (flow control). The last thing we should know about is delimiters. Sometimes an STX and ETX pair is used for transmission/reception as well. Finally, we might also come across an ACK/NAK pair. RS-232 has a lot of information to absorb, so feel free to reread it.

Episode 253 | Kyle Scarmardo - Motivation Matters
Kyle Scarmardo talks with Dave Rael about being deliberate with your time, the importance of self-awareness, coaching and mentoring, and taking action Kyle spent sixteen years in the Information Technology space for a large financial company, the 20th largest private company in America, where he worked his way up from the bottom to become an executive in 13 years at the age of 35. The latter part of his career heavily involved helping others with self-improvement, career growth, improving executive function, applying new strategies to better communicate and influence, and assist with culture change. In this work Kyle tapped into a passion that ultimately would pull him away from a full time focus on technology. Kyle now spends more time assisting others looking to accelerate their careers, become more effective leaders, and take self-improvement to a deeper introspective level.
