Thanks BDPA

I wanted to share a success story about how BDPA helped me in my career recently. Some history on me, I’ve had the pleasure of serving as the past president for the Charlotte BDPA chapter and as an educational instructor for their High School Computer Competition program. I participated in BDPA as a way to give back to my community and a way to expose young black folks to the career of IT.

I had been working a job with LogiXML, great pay but it was a 100% travel. At the time I had a 7yr and 14yr old at home and my wife was working full time. Needless to say my traveling was wrecking chaos on the family. So I decided to find a job close to home.

I happened across a job posting from a recruiting firm, Ciber. It turns out I had met someone who worked at Ciber and I recall meeting her through BDPA. So I gave her a ring. Turns out she no longer worked with Ciber but she put me in touch with the right people and gave me a good recommendation.

Three weeks later I was hired at Duke-Energy, contracting through Ciber. Great pay, great folks and good hours. I'm still here almost a year later.


I thought I’d share this with folks for two reasons. First, we network today for what we may need tomorrow. And secondly because I wanted to express my appreciate for what BDPA has done for me in my career.

MSSQL - When does data move from Memory to Disk

So I had to ponder this question (I had a vague idea but wanted to get a firm understanding)

Question: We know SQL stores data objects in RAM as it needs, at what point does the changes that are made in RAM get written to the disk?

In layman's terms: In the background the server monitors it's memory. When a particular object has not been used "in a while" that object is moved to disc. It is at this point that the disc and memory are syncronised. This is also done on a proper shutdown of the SQL Server.

Side Note: If memory is full of objects that are frequently used, SQL Server will read directly from disk. This can negatively impact performance in a substantial way.

From Wikipedia (link):

SQL Server buffers pages in RAM to minimize disc I/O. Any 8 KB page can be buffered in-memory, and the set of all pages currently buffered is called the buffer cache. The amount of memory available to SQL Server decides how many pages will be cached in memory. The buffer cache is managed by the Buffer Manager. Either reading from or writing to any page copies it to the buffer cache. Subsequent reads or writes are redirected to the in-memory copy, rather than the on-disc version. The page is updated on the disc by the Buffer Manager only if the in-memory cache has not been referenced for some time. While writing pages back to disc, asynchronous I/O is used whereby the I/O operation is done in a background thread so that other operations do not have to wait for the I/O operation to complete. Each page is written along with its checksumwhen it is written. When reading the page back, its checksum is computed again and matched with the stored version to ensure the page has not been damaged or tampered with in the meantime.[58]

On Creating a Startup

Repost: http://onstartups.com/tabid/3339/bid/43774/The-5-Minute-Guide-To-Cheap-Startup-Advertising.aspx

I recently advertised my developer's guide to launching a startup on StumbleUpon. The plus side of StumbleUpon is that all clicks are 5 cents. The downside is the bounce rate is high since people are basically channel surfing. I achieved a 96.88% bounce rate in my experiment, with an average stay of 2 seconds. I wonder if it was something I said? In my test, only 25 visitors stayed longer than 5 seconds. I paid $50 for 1000 clicks, but since only 25 of them stayed long enough to read anything, I effectively paid $2 per click. Your mileage may vary, but through this and other experiments I've gathered the following tips for advertising on StumbleUpon:
  • Your #1 goal is to get stumblers to stay longer than 5 seconds. Your #2 goal is to get them to up-vote your page. Paying $50 for 1000 clicks is one thing. Having it go viral and receiving 10,000 clicks for the same price is another.
  • Don't send StumbleUpon traffic to a landing page that asks for an email address. StumbleUpon users are notoriously fickle about providing their email.
  • People stumble to be entertained, so if your page doesn't have the potential to go viral or turn into linkbait, you will not likely fare well.
  • Blog-like content and videos seem to work best. Anything that resembles a traditional landing page will bomb.


In 24 hours, my listing was shown 26,050 times (to 3,187 unique visitors). The link in my ad was clicked 419 times, resulting in a unique click through rate of 13.15%. Not bad – that’s about $0.09 per click.


Timing of your email and Tweets
Timing is also a very important aspect for getting you covered. The best days for traffic for getting coverage of your story I have learnt are Tuesday, Wednesday and Thursday. Monday is way too fast to get you written up, the inboxes of reporters are full it's just not a great day.
At the same time, I learnt that, whilst Fridays aren't as good for traffic, the news is slower. So your chances of getting covered on that day can be higher. With a recent story about Buffer on Mashable, I took advantage of this. I followed up on a story I had pitched earlier in the week. Since it was extremely busy, I wouldn't get a response, yet a quick follow up email on Friday would receive an immediate response.
