HybridCurve··on Home schooling's rise from fringe to fastest-growing form of education
American Evangelicals seem to gravitate toward their belief as a form of authoritarianism. It's less about compassion and more about incontestable moral authority over others.
HybridCurve··on Google Brain founder says big tech is lying about AI danger
> "Don't worry if our adversary develops nuclear weapons and we won't - it's OK we'll just use theirs"

Beneath this comment is hidden a truth that there is AI which can be used beneficially, AI which can be used detrimentally, AI which can be weaponized in warfare, and AI which can be used defensively in warfare. Discussions about policy and regulation should differentiate these, but also consider implications of how this technology is developed and for what purpose it could be employed.

We should definitely be developing AI to combat AI as it will most certainly be weaponized against us with greater frequency in the near future.

HybridCurve··on Linear Algebra Done Right – 4th Edition
If you think a textbook is good, the digital edition should available for review as they will often be invaluable in hardcopy for continued reference. I am pleased the author adheres in some part to this mode of thinking.
HybridCurve··on Static Analysis Tools for C
I agree that CTU analysis makes it better. There are also a bunch of tunables for the clang analyzer that you can take advantage of that suites like CodeChecker do not fully allow access to or take advantage of.
HybridCurve··on *(char*)0 = 0; – What does the C++ programmer intend with this code? [video]
I hated that about DOS, real-mode and BC++. After about 6-8 months of that misery, installing linux and learning to write C code with GCC was the best thing that ever happened to me. I felt like an animal being released from a cage and into the wild.
HybridCurve··on HP fails to derail claims that it bricks scanners on printers when ink runs low
If you come across a newer HP printer, the best thing you can do with it is disassemble it for parts to make other things. They are full of precision rods, rotary encoders, DC motors, and such. If it has a built-in scanner, you'll also get a contact image sensor and a decent pane of glass. But on no circumstances should you ever expect rely on it to function as an output or input device.
HybridCurve··on LLMs confabulate not hallucinate
I fully agree with this perspective. The terminology will change as the field continues to evolve. As long as any anthropomorphizing terms are chosen carefully and are not aggrandizing, it shouldn't be a problem. IIRC "hallucinate" was a term previously used to describe characteristics other network types such as RBMs and had just been carried over to LLMs.
HybridCurve··on F-35 can’t be found after pilot ejected
You have to remember the GWOT was fought against ill equipped combatants, unarmored vehicles, and cinderblock structures. The US is generally not worried about those types of threats in planning for future conflicts. There is a reason why Ukraine is getting F16s and not A10s: The Russians brought more than just AKs and Toyota Hiluxes across the border. The A10 is a good aircraft but times have changed and we have much better platforms now.
HybridCurve··on Game developers flee Unity after exorbitant price plan announced
It's difficult to tell if this is the result of bad management forcing the company to enact a poor market strategies or sabotage.

Developers can invest a significant amount of time and resources building tools, supporting systems and workflows around these engines that aren't necessarily portable to other engines. There is also a significant time investment in learning the API, engine internals, and nuances of operation. Disrupting revenue streams so aggressively for the licensees is only going to result in breaking trust between Unity and their customers, driving them away permanently. They can also forget about taking on any new customers as few will be willing to move to a platform which tries to aggressively limit their choice of income model.

While Unity has filled a niche in it's usefulness, there are much better offerings (either higher or lower on the spectrum of capabilities) for other proprietary engines and a few under-featured free engines. They are not irreplaceable.

I do feel bad though for all the Unity developers that are having to deal with this but at the same time I think that many might have anticipated something like this would happen for some time.

HybridCurve··on Under Musk, Twitter is handing over more data to investigators
The irony here is there was some discussion recently about how twitter did not hand over all the data to investigators regarding Trump's PMs.
HybridCurve··on “Most notorious” illegal shadow library (LibGen) sued by textbook publishers
> Publishers suing include Cengage Learning, Macmillan Learning, McGraw Hill, and Pearson Education.

There was a time when I would buy books without being able to review all of the content. That stopped several years ago after buying two textbooks (one from McGraw Hill, another Pearson) that were so awful I returned them. They were both full of absolutely horrid page layouts with huge margins full of irrelevant information, just absolute garbage. I don't think they are losing money because their content is being distributed for free, but rather it just has little to no value and is not worth investment.

HybridCurve··on U.S. Department of Defense Launches All-Domain Anomaly Resolution Office Website
It's entirely possible the government exposes individuals with SCI type clearance to disinformation or fabrications to convince them they are real, and then watches them to see if they can keep it a secret. This would be a ideal way to conduct audits within groups exposed to leading technology. Then, to be fair, many of these people are conveying their observations truthfully but were just encouraged to draw to wrong conclusions from the experience.
HybridCurve··on Linux guide for power users (2022)
We use gentoo because a linux system without problems is boring.
HybridCurve··on LK-99: Team of Southeast University observed zero resistance below 110 K
One of the most well known, YBCO, has a Tc of 95K.
HybridCurve··on Horrifying numbers of Americans will not make it to old age
Apples to oranges comparison.

We know the healthcare system in Britain has been suffering from neglect for some time and AFAIK doctors often either work for the NHS or are independently contracted by them. Also, while Buc-ees technically a convenience store, it also a gas station (they held the record as the world largest with 120 gas pumps)with a large deli, tons of groceries, and the cleanest bathrooms you will ever find off the highway. They do a lot of business and have a large team of of very busy workers. Their income is well earned. That said, healthcare workers are very underpaid in Britain and have been for some time, but it's not fair to compare the incomes while trying to diminutize Buc-ees by simply labelling it as "convenience store".

HybridCurve··on The future of Clang-based tooling
This is another part of clang I've considered be almost, but not quite there yet. Some of the calls to the API are not very intuitive and they left too much out of libclang for it to be of anything but limited use. I am not a C++ guy, and it would be far too difficult for me to learn on a project such as this for my purpose so I had to use GCC instead. GCC has fairly good internals documentation (not just doxygen, thankfully) and the code is reasonably well annotated so it was't too difficult to work with.
HybridCurve··on The future of Clang-based tooling
I haven't seen any recent comparisons but the most recent benchmark I saw was that gcc/clang were close. I'm sure the speeds vary quite a bit depending on project size, options, available RAM, etc. IIRC using LTO makes linking significantly more resource intensive and I would assume this is where most of the disparities in performance are.
HybridCurve··on US Army Field Manual on Leadership (1990) [pdf]
This is a bit of a biased take. The military uses a purely authoritarian system of management which is entirely different from anything in a civilian occupation. There really is no free choice in an authoritarian system and failure to follow lawful orders results in strict penalties. Having bad leaders in an authoritarian system (there are many in the military) effectively amplifies the problem they create which is likely where this bias comes into play.

Leadership in the military works different than in other institutions. It is one of the only systems that I know of where authority is bound with responsibility. As a leader you are held to account for your actions and the actions of your subordinates because of your authority over them(IMO police should be held to at least this standard if not higher as they are granted permission to assault, detain or use lethal force against anyone as they see fit). It is common for NCOs to be reprimanded for the failings of the subordinates because it is often characterized that the leader failed them because they did not train or oversee them properly. There is some fault tolerance built in (with leaders spot checking leaders below them by checking their subordinates) but the system will break down if you have multiple levels of failed leaders within the chain of command.

The truth in the military though, is that this authority is mostly an illusion. There are many terrible leaders that do not understand this. They believe once you attain a position you are entitled to give whatever orders you like and that people cannot refuse them. This is true in civilian life as well as military. However, a good leader knows that their subordinates grant them authority over them. Understanding that, this is where much of the military leadership philosophy comes into play: lead by example, taking care of your team, morale, etc. These things are of much more critical importance in military roles because of the levels of risk, tension, and stress are often very high.

HybridCurve··on The future of Clang-based tooling
Having worked with clang (and gcc) quite a bit, there are a number of good points the author makes. There are a lot of cool things llvm/clang has, but it feels like a lot of the tooling does not mesh together as well as it should and some things lack refinement.

My biggest gripe overall (since it could be fixed easily) is the compile_commands.json. It's used by a number of tools and is generally awkward, cumbersome, and has a handful of shortcomings. To fix these issues, I used the intercept-build system provided with LLVM to generate a more succinct build file in JSON format that abstracts certain options (like paths) and groups options commonly found together. The reason for this is that sometimes you might be generating llvm bitcode, building clang AST, running clang-analyze, or translating the build options to work with either compiling or linking with GCC or Clang. For many of these it helps to be able to alter options easily, which you cannot do with the compile_commands.json file alone.

There are a number of areas like this where clang would benefit greatly, without demanding an enormous amount of effort.

HybridCurve··on The Danger of Popcorn Polymer: Incident at the TPC Group Chemical Plant [video]
Here is the PDF report from the CSB:

https://www.csb.gov/assets/1/17/tpc_factual_update_10-29-202...

Bottom of page 7 it explains the mechanism. Essentially butadiene peroxides react with the butadiene to form the polymer 'seed'. The polymer is not stable and expands, increasing in volume.

HybridCurve··on PCSX2 is an open source PS2 Emulator
Experiencing the late game plot is like riding on a train that derails with all the cars suddenly separating only to reconnect forming a giant unicorn which dives into the water and swims away.

If anything, the synopsis was toned down a bit.

HybridCurve··on To make more stingers, U.S. needs to revive production technology from scratch
> And nobody flies aircraft at "treetop level", with the possible exception of the A10...

Helicopters fly this low all the time.

HybridCurve··on How the most popular cars in the US track drivers
This was my take when people suggest older cars as an alternative. Safety has improved dramatically in the past 20-30 years, especially with side impacts where fatalities or serious injury can be common. It's one of the few reservations I have when driving my '91 BMW.
HybridCurve··on Reddit CEO Triples Down, Insults, Whines
I don't understand the impulse to aspire to be like an insufferable asshat (musk). Is this some kind of power thing to be a famous/infamous figure of industry that gets to be an absolute piece shit with impunity?
HybridCurve··on The Rot Economy
In this you are likely correct. It's really anything that is allowing unlimited money (goods or services) to flow into campaigns from industries or unknown origins. It's also the court which is limiting voting rights. Those are two good starts which will help shift power back to the electorate.

I mean, it's bad that in our country we have to consider boycotting companies that donate to or support politicians/legislation which work to undermine democracy and such. This is plainly indicative of a broken system, where participating at the ballot box is insufficient to overcome corporate interests.

HybridCurve··on The Rot Economy
While some of these solutions are good, I don't think any of them will make it through congress until well after Citizens United is appealed. TBH, trying to fix any problem of consequence in the US requires a functional Supreme Court, which we don't have.
HybridCurve··on Tell HN: Comcast/Xfinity is having a widespread DNS outage
When comcast started redirecting my mistyped URLs to their own pages, I stopped using their DNS. No regrets.
HybridCurve··on What motorcycles teach about maintenance
I agree here: Cost of maintenance from time, parts, tools, space and accessibility are all lower here. Also, as a whole system, a bike is more simple than a car. The only downside I can think of is that a bike is much less forgiving to mistakes.

As a car person I am a bit envious and long for the day when cars could be smaller, cheaper, lighter, and more simple.

HybridCurve··on How to Actually Break Reddit
Agreed. It's not going to get better. You can't force changes on users who generate and manage all the content on your site.
HybridCurve··on How to Actually Break Reddit
When I first started browsing reddit many years ago, I remember the comments and user contributed information to be of decent quality. Now there are many topics with page after page of irreverent half-assed humor. I am not really sure where the blame lies for this (mods, user culture, bots, etc...) but the quality of content on the site dropped dramatically over the years to where most of it is just garbage or noise. I really don't think that can ever be fixed.
