What Has Life Taught Him Through Miracles.

Our favorite operating system is now changing the default shell (ksh) to enforce not allowing invalid NUL characters in input that will be parsed as parts of the script.

The commit message reads,

Modified files:
	bin/ksh        : shf.c 

Log message:
If during parsing lines in the script, ksh finds a NUL byte on the
line, it should abort ("syntax error: NUL byte unexpected").  There
appears to be one piece of software which is misinterpreting guidance
of this, and trying to depend upon embedded NUL.  During research,
every shell we tested has one or more cases where a NUL byte in the
input or inside variable contents will create divergent behaviour from
other shells.  (ie. gets converted to a space, is silently skipped, or
aborts script parsing or later execution).  All the shells are written
in C, and majority of them use C strings for everything, which means
they cannot embed a NUL, so this is not surprising.  It is quite
unbelievable there are people trying to rewrite history on a lark, and
expecting the world to follow alone.

The work of improving ssh security by segregating functionality into separate binaries contiues, this time by introducing sshd-auth as a separate binary.

The commit message summarizes why this makes sense,

Splitting this code into a separate binary ensures that the crucial
pre-authentication attack surface has an entirely disjoint address
space from the code used for the rest of the connection. It also
yields a small runtime memory saving as the authentication code will
be unloaded after thhe authentication phase completes.

The code is in snapshots as we type.

I don't have a lot to say about the recent midterm election results.

• I was surprised by how poorly the Republicans did
• The American right needs to think long and hard about its political positions -- what they are, and how to communicate them to Americans in a persuasive way
• Candidate quality matters, and Trump has terrible judgement on this
• It's embarrassing that the results of the election aren't fully known almost a week later.

It seems like elections should be a lot easier. We've made them harder than they need to be.

• In-person voting on a single day, except for deployed military or invalids.
• Paper ballots, counted at the precinct. Properly maintain chain-of-custody records for ballots.
• Show identification to vote.
• Dip your thumb in purple ink after you've voted.

This isn't rocket science. All the fancy machines and alternate voting methods have made elections too complicated to administer in a transparent and credible manner.

Spear phishing jest oszustwem o charakterze socjotechnicznym, wykorzystującym presję autorytetu i czasu, aby skłonić atakowanego do podjęcia niekorzystnego dla niego działania. Fakt, że zazwyczaj informacje potrzebne do przeprowadzenia ataku są publicznie dostępne lub łatwe do uzyskania, czyni to oszustwo popularnym wśród cyberprzestępców.

In July 1776, our founding fathers joined together and signed this countrys Declaration of Independence, declaring every American citizens access to certain inalienable rights. The document was adopted by the Continental Congress on the fourth.

The spirit of that message and the rights to which we are all entitled seem particularly embodied by entrepreneurship. While the landscape of America has changed in ways those men could never have imagined, they still had at their core the same principles that mark the entrepreneur of today.

We all know someone who divulges a little too much information on the Internet. Whether it is the friend who Instagrams every meal or the relative who constantly posts updates on how Fidos doing, this phenomenon seems well on its way to pervading all the social media we use. Maybe you have even caught yourself posting a bit too much. While something that everyone seems to be doing may appear harmless enough, oversharing can have some negative consequences of which all social media users should take note.

Why Over Sharing Might Be Hurting You
