You are more likely to play in the NFL than become an astronaut

Consider playing in the NFL as the epitome of sports – and being an astronaut as the epitome of a STEM career. In both cases, postulate that college is where you can reasonably draw a line for determining basic qualification for application. In the case of the NFL, to reasonably apply to the NFL you must at minimum play NCAA football. In the case of an astronaut, you must at minimum have a Bachelor’s degree in a STEM-related field. Fair enough?

The NFL statistics are summarized in this graphic (via @GatorsScott) –


The relevant numbers are: 15588 NCAA seniors playing football, of which 256 are drafted to the NFL, or 256/15588 = 1.6%. (note, these numbers are from 2013, via a study commissioned by the NCAA.)

This year’s astronaut corps application had a total of 18,300 applications. The minimum education requirements to apply are “a bachelor’s degree from an accredited institution in engineering, biological science, physical science, computer science or mathematics. An advanced degree is desirable” (about a third of astronauts have an MS, and a third have PhDs). There will be 8-14 open slots, so lets assume the maximum for best possible probability: 14/18,300 = 0.07%.

Now, this doesn’t disprove the so-called STEM shortage – the evolution of the modern-day disposable academic suffices to do that on its own. It is however a cautionary tale about the rhetoric we use when we tell children to “reach for the stars”. Thats good for *children*, but as advice to college students, it’s terrible. A child should be encouraged to dream, and dream big. A college student is practically an adult and deserves to hear stark realities about the job market because that is precisely the moment in time where they can have to make decisions about the rest of their life – decisions that should be informed by those dreams, but not dictated by them.

There are a lot of astronauts and NFL players who decided from day one that was what they were going to do, and succeeded. And that is amazing. But there just isnt enough room for everyone who is equally capable and has the same amount of sheer determination and talent to do the same. We don’t need 18,300 astronauts, nor do we need 15,588 NFL players drafted every year.

upgraded to ASUS RT-AC56U router – speed tests

As per my router troubles earlier, I have finally upgraded to the Asus RT-AC56U. I’ve been using an old Linksys WRT54GL as an access point for legacy 802.11g connections, so here is the baseline for comparison, using a desktop machine located two feet away, using built-in wifi antennas:

Linksys WRT54GL, 802.11g, 2.4 Ghz

here’s the result from using the new router:

ASUS RT-AC56U, 802.11n, 2.4 Ghz

here’s the result from using the new router on my main workstation PC in the basement, using a PCI wifi adapter:

Linksys WRT54GL, 802.11g, 2.4 Ghz

and using the new router, with a USB AC-1200 wifi adapter (ASUS USB-AC56):

ASUS RT-AC56U, 802.11ac, 5.0 Ghz

my Netgear WNDR3700 (v1) router’s 5 Ghz network just went missing – bad antenna?

As this is a geekblog, I might as well document my woes here in public. Here is the support ticket I filed with Netgear just now.


I purchased a WNDR3700 on 1/11/2011 – serial number 21840B550A390. I have registered the router on

this week the 5 Ghz wireless network stopped working entirely. I have updated to latest firmware, and also:

– the 5 Ghz blue light is on
– the settings on the configuration dashboard ( indicate the 5Ghz network is active
– SSID for 5 Ghz is set to “broadcast SSID name: on”
– the 2.4 Ghz network works fine, computers connected can access internet
– computers attached to the router via ethernet also can also access the internet normally

however no device capable of 5Ghz is able to detect the 5Ghz SSID. the scanning software inSSIDer does not detect any 5Ghz network being broadcast either.

Logically, maybe the antenna or antenna amplifier has burned out, I can think of no other explanation in software for why 5Ghz is missing – the router itself is convinced that 5Ghz is indeed working, but it isnt. That suggests a hardware problem to me.

The router is only 2 1/2 years old and my previous Netgear routers are still going strong at my relatives’ homes after 5-6 years so this is very surprising. I am hoping Netgear support will not disappoint me.

It looks like other users have reported similar issues with the 2.4 Ghz network also mysteriously vanishing, which is why I think my diagnosis of a bad antenna is correct. To be honest I was never enamoured of the speed of this router to begin with, as my initial tests showed.

ASUS RT N66U router

I am skeptical that Netgear will be willing to replace the unit but if they make some kind of gesture that will go a long way towards persuading me to buy a Netgear replacement. I’m not going to bother with a draft 11ac router, all I need is a solid 11abgn machine with some MIMO and I’ll be happy. Unless they make me a good deal, I am very tempted to ditch Netgear. For example, that ASUS RT-N66U “Dark Knight” got a nice review. External antennas, too!
