Let's Encrypt NearlyFreeSpeech.net Update

2016 Nov 5, 8:59

Since I had last posted about using Let's Encrypt with NearlyFreeSpeech, NFS has changed their process for setting TLS info. Instead of putting the various files in /home/protected/ssl and submitting an assistance request, now there is a command to submit the certificate info and a webpage for submitting the certificate info.

The webpage is https://members.nearlyfreespeech.net/{username}/sites/{sitename}/add_tls and has a textbox for you to paste in all the cert info in PEM form into the textbox. The domain key, the domain certificate, and the Let's Encrypt intermediate cert must be pasted into the textbox and submitted.

Alternatively, that same info may be provided as standard input to nfsn -i set-tls

To renew my certificate with the updated NFS process I followed the commands from Andrei Damian-Fekete's script which depends on acme_tiny.py:

python acme_tiny.py --account-key account.key --csr domain.csr --acme-dir /home/public/.well-known/acme-challenge/ > signed.crt
wget -O - https://letsencrypt.org/certs/lets-encrypt-x3-cross-signed.pem > intermediate.pem
cat domain.key signed.crt intermediate.pem > chained.pem
nfsn -i set-tls < chained.pem
Because my certificate had already expired I needed to comment out the section in acme_tiny.py that validates the challenge file. The filenames in the above map to the following:
  • signed.crt is the Let's Encrypt provided certificate
  • account.key is the user private key registered with LE
  • domain.csr is the cert request
  • domain.key is the key for the domain cert

4 people are living in an isolated habitat for 30 days. Why? Science!

2016 Feb 1, 3:27

nasa:

This 30 day mission will help our researchers learn how isolation and close quarters affect individual and group behavior. This study at our Johnson Space Center prepares us for long duration space missions, like a trip to an asteroid or even to Mars.

image

The Human Research Exploration Analog (HERA) that the crew members will be living in is one compact, science-making house. But unlike in a normal house, these inhabitants won’t go outside for 30 days. Their communication with the rest of planet Earth will also be very limited, and they won’t have any access to internet. So no checking social media kids!

The only people they will talk with regularly are mission control and each other.

image

The crew member selection process is based on a number of criteria, including the same criteria for astronaut selection.

What will they be doing?

Because this mission simulates a 715-day journey to a Near-Earth asteroid, the four crew members will complete activities similar to what would happen during an outbound transit, on location at the asteroid, and the return transit phases of a mission (just in a bit of an accelerated timeframe). This simulation means that even when communicating with mission control, there will be a delay on all communications ranging from 1 to 10 minutes each way. The crew will also perform virtual spacewalk missions once they reach their destination, where they will inspect the asteroid and collect samples from it. 

A few other details:

  • The crew follows a timeline that is similar to one used for the ISS crew.
  • They work 16 hours a day, Monday through Friday. This includes time for daily planning, conferences, meals and exercises.  
  • They will be growing and taking care of plants and brine shrimp, which they will analyze and document.

But beware! While we do all we can to avoid crises during missions, crews need to be able to respond in the event of an emergency. The HERA crew will conduct a couple of emergency scenario simulations, including one that will require them to maneuver through a debris field during the Earth-bound phase of the mission. 

image

Throughout the mission, researchers will gather information about cohabitation, teamwork, team cohesion, mood, performance and overall well-being. The crew members will be tracked by numerous devices that each capture different types of data.

image

Past HERA crew members wore a sensor that recorded heart rate, distance, motion and sound intensity. When crew members were working together, the sensor would also record their proximity as well, helping investigators learn about team cohesion.

Researchers also learned about how crew members react to stress by recording and analyzing verbal interactions and by analyzing “markers” in blood and saliva samples.

image

In total, this mission will include 19 individual investigations across key human research elements. From psychological to physiological experiments, the crew members will help prepare us for future missions.

Bank robbers use KVM switch and 3G router to steal money

2014 Apr 28, 10:01

Using social engineering to install a remote-controlled keyboard-video-mouse (KVM) switch on bank PCs, the gang managed to transfer millions to outside accounts in two separate jobs in April and July of 2013. They were caught attempting to rob a third bank in September.

FitBit and WebOC Application Compatibility Errors

2013 Aug 29, 7:17
I just got a FitBit One from my wife. Unfortunately I had issues running their app on my Windows 8.1 Preview machine. But I recognized the errors as IE compatibility issues, for instance an IE dialog popup from the FitBit app telling me about an error in the app's JavaScript. Given my previous post on WebOC versioning you may guess what I tried next. I went into the registry and tried out different browser mode and document mode versions until I got the FitBit software running without error. Ultimately I found the following registry value to work well ('FitBit connect.exe' set to DWORD decimal 8888).
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION]
"Fitbit Connect.exe"=dword:000022b8

For those familiar with the Windows registry the above should be enough. For those not familiar, copy and paste the above into notepad, save as a file named "fitbit.reg", and then double click the reg file and say 'Yes' to the prompt. Hopefully in the final release of Windows 8.1 this won't be an issue.
