How to Connect Your WordPress Blog to Social Services Like Linkedin – A Guide

Chris Lange asked how I have my WordPress blog posts appear on Linkedin, so here’s a brief guide.

Log into your WordPress account and select Settings –> Sharing from the navigation menu on the left-hand side of the page.

The WordPress Settings/Sharing Menu Item

At the top of the page, there are the Publicize boxes, including Linkedin. Click on “Add new…”, authenticate, and you’re done!

Starting the Day with a Restore

Current smartphones are kid magnets. They have an unlimited supply of movies, shows, and games, and they fit nicely into small hands and provide a great screen size for viewing by small people.

It feels like our two kids are constantly clamoring for one of phones, and I’ll freely admit that I’m guilty of handing it over now and then so I can get a bit of piece and quiet, and I’ve seen my wife do the same. Our phones are different with regards to access though.

For her phone, it’s touch the home button and off you go. For mine, a security PIN is required, due to the fact that I access my work email account through it. The security settings are set remotely and it will wipe the phone if the PIN is entered incorrectly 5 times.

You can see where this is going.

A few years back, my oldest son wiped my phone a few times, so I’ve been extra-careful to keep it away from him and have had the talk with him about what to do if he finds my phone and it puts up the numbers screen. This morning he forgot all that, and wiped my phone about 30 minutes before I was going to walk out the door.

So it was a “restore the phone” morning. The good news is that my backup was only two days old, so I only lost a few photos. The bad news is that they were some photos I took of the kids when we were out together, and I had a couple of great shots. But all in all, no big deal, other than some annoyance and driving to work with my laptop on the seat next to me doing the restore.

Moral of the story: when was the last time you backed up your phone and it’s data?


The Oatmeal sums it all up, uh, nicely.

Data Acquisition and Analysis, and Startups

I had dinner at my in-laws over the Christmas break, and my brother-in-law’s father is a retired Boeing engineer in his 80’s that used to work in their wind tunnels. He shared some great stories of how moving from analog to computerized methods solved many problems for him and his team, especially around data acquisition and analysis, and it made me think of startups.

One area in particular that got much easier for them was recording air pressure over airfoils at various speeds and angles of attack. They used to have air pressure sensors attached to dozens of needle gages that were mounted on a nearby board. They’d crank up the fan to the desired speed, adjust angle accordingly and snap a few pictures of the gages. Any change of speed or angle would have them taking more photographs of the gage board.

The reason they’d take a few pictures per setting was that the needle gages had a lot of noise – they’d bounce around the scale and they needed multiple pictures to average/guess what the “real” reading was across all the photographed readings per wind speed and airfoil angle setting.

The time from taking a photo and then having it developed, examined, and compared to others in the series to record the results of the experiment in order to compare the tabulated data against the calculated model could be weeks. You can also imagine all sorts of ways that errors could creep into the dataset using this method.

In engineering today, most of this type of data is now either simulated entirely inside the computer or the computer collects massive amounts of data for further analysis. Data is the new coin of the realm, and the bigger your dataset, the larger the opportunity you have to exploit it for financial gain and hit your target.

Disk is cheap and missing the signal in the noise is expensive.

If your startup isn’t already generating and analyzing datasets or considering which you may create or have, you might as well be taking photos of physical gages in your quest to build a rocket to the moon.
