#Science is about uncovering #truth; #security positions which are not based on science seem to typically be based on #fear. Fear allows acting on contradictory beliefs. Logic has the principle of explosion, "ex falso quodlibet". In security we might say "ex metu quodlibet": "out of fear, anything".

If your #FourthFactor of #authentication is "ask someone else to check" (email provider, phone service provider, "someone you know", etc) it's not a fourth factor, it's just #DelegatedAuthentication like #SingleSignOn #SSO. They will rely on have/know/are to authenticate the user. #hottake

Why do I #dox myself? I feel low risk (loss × odds) from all but nation-state actors, and the most threatening of those knows more about me. Sharing increases my #security by making attacks more visible. Additionally, #trust is built from history and stakes, so linked identities fast-tracks trust.

Just a quick reminder - #humans are #efficient at pursing their #values, not #lazy. If your actions don't match the values you want to have, you have #cognitivedissonance and an opportunity to #improve. Many unwanted actions I've seen try to secure against prior violations of #trust; hard to regain.

I am #grateful for the #gospel of #JesusChrist, for the restoration, for the #BookOfMormon, for my wife, for our happy #pets, for the #Internet, for our warm house and sufficient food, for vehicles and roads, for living in a time and situation of relative #peace, for #technology and opportunities.

Found out today the #syncthing android app #syncthing-fork maintainer changed again, and am a bit nervous. I was affected by The Great Suspender handover. I deeply appreciate those who spend time on #opensourcesoftware - especially those that give out support. Sadly gratitude doesn't pay a mortgage.

A few days ago I got a piece of pepper in my eye while eating dinner. It was gritty and burned. I expressed that this #life is a time to enjoy experiences we might not otherwise get to try, and this was my first time trying that one. It was painful, but the context was humorous.

Just finished reading about #sparta #history acoup.blog/2019/08/16/c.... The last section concludes "Sparta is not something to be emulated. It is a cautionary tale." When I started I thought I'd find something about super soldiers, but slavery and nobles instead... :P. Good #reputation though.
Collections: This. Isn’t. Sparta. Part I: Spartan School
This is Part I of a seven part series (I, II, III, IV, V, VI, VII, Gloss., Retrospective) comparing the popular legacy of Sparta (embodied in films like 300) with the historical ancient state. Toda…

#GenerativeAI is useful for problems that are bothersome to produce (or why hand it off?) and are easy to verify (since it's not very reliable). Domain experts can easily verify more complex things, enabling them to make better use of it in those domains.

The recursive corollary to the famous #Sturgeon'sLaw, "90% of everything is crud": "Everything* is crud. * except possibly 1 item". This follows as #Sturgeon'sLaw can be applied recursively to smaller and smaller subsets until everything is crud or only one item remains.

Saw #KPopDemonHunter and #Nimona last night with the wife. She noted that like #Frozen, both have the theme of not hiding who you are. Implies culturally we conceal. We also shouldn't be aggressively in-your-face though. What does a healthier balance look like?

I am what I choose to be. And I choose to be a disciple of Jesus Christ, a dragon, a programmer, and a teacher. None of those are easy choices, but they are some of my choices.

Your proving might not come like Joseph, Jacob, or Moroni, but it will come. Those trials are evidence of God's love, and shape us to be able to stand with Him in glory. #ElderEyring #GeneralConference

Loved the #GeneralConference message from #ElderHolland. Like the man born blind, #ElderHolland is of age; would you not give his testimony at least some consideration? The Book of Mormon in his life is like the spit and clay that healed the man born blind. He closed with #AmazingGrace.

Noteworthy lesson shared by J Anette Dennis in #GeneralConference: If something goes wrong in someone's life, they don't need your judgment. They need your support.

To be open: I do not expect to ever get a #securityclearance. I believe #EdwardSnowden did the right thing by informing the public that their public servants were lying to them. Saving an innocent life from aggression might morally justify a temporary lie. Pride and control never does.

Nothing terribly exciting happening around here recently. Applying to some faculty positions, designing my next study, and poking into some bugs for #SkyLords. Though #GeneralConference is in three days, which is pretty exciting. Expect a post or two about things I thought were interesting :).

Had some incredible Root Beer Float flavored cheesecake at a Ward BBQ on Saturday. The chef is starting a food truck locally; the Cheesecake Alchemist. I'm not getting anything for sharing this, was just really impressed.

A friend just lost some data and is investigating data recovery services. That makes today #backups awareness day. Make sure you have a backup plan for your personal files. Make sure it's automatic. Make sure you check that it's running occasionally. Backups are important. Don't lose data.

Please be sane and sober. Contrails are real, #chemtrails are not. People may lie; don't pick beliefs first and then assume those who disagree are lying #confirmationbias. Probable truth comes from reason (such as math) and from experienced patterns. Ask, "does this fit" and repeat; fix mismatches.

Starting to get out of being the third sickest in my life. Worst was chicken pox when I was around 2 or 3. Second worst was during a family trip to Disneyland in December 2019 - was out for 3-4 days. Fourth was a two-day migraine while at boarding school. Bad timing, missed a lot of #USENIX2025 :(.
