I cried this morning when I watched the live video stream of the launch of Falcon Heavy. As an Engineer, I was overwhelmed by the magnitude of all the work and planning and preparation and testing and science and engineering and everything that went into that entire project to make that launch a success.
Beyond the success of the launch itself, the proper separation of the two Falcon 9 side boosters, continued operation of the Main booster, the placement of the capsule into proper orbit, everything just worked so well. When the two side boosters returned and landed back at Cape Canaveral, within less than one second of each other, I just shook my head in amazement and bawled with more joy.

I have on my website a link for people to submit writing topics for me.
Responding to readers requests helps me stay focused on things which interest my readers and also encourages me to write about things I might otherwise never get round to. For these reasons, I’m always grateful to my reader when they submit a question.
Reader Sean W. recently asked this question:
Will Mobile Operators make the investments in 5G required to meet consumer price points?
David Dean was a long-time salesman with a very successful track record. He began his sales career selling books for the Southwestern company during summer recess while attending university.
This book is in the genre of motivational or self-help.
The book chronicles his sales efforts during several of those summers and he uses his own experiences to illustrate 7 principles which he believes are important to success in any endeavor. These little vignettes tie the book together and give it a helpful air of storytelling. Continue reading “Now is Your Time to Win – David Dean”
Did you ever start working on an Excel spreadsheet and realize you needed it to do something you didn’t know how to do? I’ve been working on the next article in my Excel BTS Project Tracker series. I needed an Excel Hierarchical List, and I didn’t know how to do that. I have to learn a couple new things to do that and I wanted to share that with you.
The trial and error approach is an agonizing way to find the key to learning something new. Often, there is a deadline, your boss wants the spreadsheet done pretty quickly. What if one of your coworkers recently presented an Excel spreadsheet that was very good, and you feel like yours needs to be equally good or it will suffer by comparison?
I need to list all the BTS and every task for each BTS. You might need to do something similar. Examples I can think of include documenting port cards in an RNC, or maybe DS-3 circuit IDs and DS-1 assignments, or mapping trunk group and trunk numbers. Anyplace where there is hierarchical numbering you might have to do something similar.
Of course, there are applications for this outside of Telecoms, too. How about sample tests grouped together, or deliveries addressed to different postcodes, or student IDs in different grades. I’m sure you can think of many more.
I tell you, these days the workplace can be so competitive. You might quickly be left behind if you aren’t continually upgrading your skills by reading the right blog. Excel is definitely one of the skills you need to constantly be improving. Continue reading “Excel Hierarchical List”
During the late 1980s, I was attending university and living on the beach in San Diego. My studies required me to spend a considerable amount of time on the beach (ahem!) and I started using a sunscreen product from Neutrogena. The sunscreen had the requisite SPF 30, but I liked it because
it had a great texture and felt good for my skin. To me, it seemed more like a skincare product than the typical sunscreen lotions and oils I used to use. It sold for around USD7.00 for a 30ml tube.
I remember once going to buy more but was unable to find it in the sunscreen section. However, I noticed a very similar-looking product in the cosmetic section. The similar product was being sold as a face cream, which also had SPF 30. The price was comparable to the other face creams around it, which was about three times as much as the price of the sunscreen product. Continue reading “A Critic of Marketing Repents”
In writing about Historical Forecasts I want to know if you’ve been following this series? I’ve written in detail about all the steps to put together a project tracker that was easy to update, quick to use, and did most of the work automatically. It’s my strong belief that any Excel Workbook which you use frequently should conform to my 3-step Mantra: Update, Refresh, Share.
What this means is that you have to do a little more work up-front, in designing and building the workbook. This up-front work gives you automation. So that when you use the workbook, all you have to do is enter any updates, refresh the pivot tables, and that’s it, you’re ready to share the new data. No additional or separate steps are required to update any charts or other workbook elements. It’s all done for you automatically! Update, Refresh, Share!
The point of this mantra is that Excel can do most of the work for you if you set up the Workbook properly. I use this approach throughout this series of articles to show you how to do that. It does take a little extra work at the start. But the payoff is a fully automated workbook which is very quick to use.
And after you’ve used these techniques a few times, two things will happen. First, it will become much easier for you to implement other Excel trackers and dashboards using these techniques. It won’t be long before you are implementing these automated workbooks faster than you read my articles about them. Continue reading “Historical Forecasts for Your BTS Project Tracker”
I manage several low-traffic websites sites. These sites use the classic 2-server Apache/mod_perl architecture. The front-end server is a light Apache instance hosting a WordPress blog. The heavy, back-end server is mod_perl-enabled Apache serving various web applications I’ve created.
To the best of my understanding, mod_perl/Apache can only set-up and cache a single database connection. Is that right? Only one database connection per mod_perl instance?
But my applications need to access several databases. All the databases are hosted on a single instance of MySQL. I’ve set it up to use that single cached database connection, and also distinguish requests from the different front-end domains. Lastly, I’m experiencing a problem using $r->push_handlers. Let me tell you about it and ask for your feedback. First, the set up. Continue reading “Single mod_perl Instance Serving Multiple Domains”
