Stephanie Weirich: How to implement the lambda calculus, quickly (50+18 minutes)
Rating: TTTT (210908)
IFL 21 keynote. The title is slightly misleading, since it's actually about how to handle binders and substitution in a simple, correct and efficient way, rather than finding the best way to normalize lambda calculus terms. The starting point is λ-calculus cooked four ways, an unpublished paper by Lennart Augustsson.
Ben Eater: How does a USB keyboard work? (34 minutes)
Rating: TTTT (210819)
Compared to PS/2, USB seems horrendously complicated, yet at the same time incredibly dumb. There is no way for a USB device to tell the computer when it has new input, so the computer has to poll devices like keyboards regularly (e.g. every 16ms or every 1m) to find out if a key has been pressed…
Steve Blackburn: MPLR 2020 Keynote (41 minutes)
Rating: TTT+ (210721)

Rich Hickey: Simple made easy (61 minutes)
Rating: TTT+ (181016) [The slides are not visible in the video]
Easy (near, familiary) is subjective, simple (unentangled) is objective. Complex (intertwined) is the opposite of simple. Complexity slows you down long-term. Benefits of simplicity: ease of understanding, easy of change, easier debugging, flexibility, modularity. State & objects are complex. Values are simple. Methods are complex. Functions are simple. Having state in a program is never simple. Code organisation does not mitigate it (unless it is completely encapsulated like in the ST monad). The first step in getting a simpler life is to choose simpler stuff (simpler tools). Abstraction. Separating how from what.

Kees Cook: Making C less dangerous [Slides] (25+9 minutes)
Rating: TTT (180907)
LWN: C considered dangerous. It's good that people acknowledge this fact, and that they are trying to do something about the problem, but the better move would obviously be to abandon unsafe languages like C, and use languages that allows things to be checked at compile time, instead of waiting for hardware support for efficient run-time checking. I'd rather have bug-free software than software that crashes all the time because of out-of-bounds memory accesses. Recent work (OSDI'18: The benefits and costs of writing a POSIX kernel in a high-level language) shows that using a high-level language instead of C is practical, with a performance overhead of only 5-15%.
Jaron Lanier: How we need to remake the internet (15 minutes)
Rating: TTT++ (180830)
I can't these things social networks anymore, I call them behavioural modification empires. Of the big tech companies, it's really only two that depend on behavior modification and spying as their business plan. It's Google and Facebook. We cannot have a society in which, if two people wish to communicate, the only way that can happen is if it's financed by a third person who wishes to manipulate them. In the meantime, if the companies won't change, delete your accounts, OK?.

Joey Hess: Type-driven configuration management with Propellor (46 minutes)
Rating: TTT (170208)
Propellor is a Haskell library that provides an ESDL for (virtual) host configuration. It uses types to avoid certain configuration errors. A certain amount of type-level programming is used to keep track of various configuration properties in the types. The lack of subtypes in Haskell seems to cause some loss of elegance (e.g. DebianLike does not imply UnixLike). Another talk.

WWDC 2016: Introducing Apple File System (36.5 minutes)
Rating: TTT (160620)
Apple is planning to replace the old HFS+ file system with a modern file system called APFS. Most features (file cloning, snapshots, space sharing) are familiar from other modern file system (BTRFS, ZFS), so this is mostly Apple catching up to the state of the art. (And it's about time!)

Two unique (I think) features are atomic renaming of directories on top of other directories, and per extent encryption.

Hard links to directory will not be supported. This is something that has been essential for the incremental backups used in Time Machine backups, but file cloning and snapshots will obviously be a much better way to implement Time Machine backups.

Michael Green: What the Social Progress Index can reveal about your country (15 minutes)
TTTT (141120)
Simon Kuznets invented GDP in the 1930s, and it was helpful back then to understand and solve the financial crisis in the USA, but he warned "The welfare of a nation can, therefore, scarcely be inferred from a measurement of national income as defined above." Today, it would be much better if governments set goals to improve SPI rather than GDP.
[The Social Progress Index is based on these twelfe factors] [Where will Brazil go next?]

Simon Anholt: Which country does the most good for the world? (18 minutes)
Rating: TTTT (140705)
National borders are becoming more and more irrelevant to the way we do business and live our lives, but national governments are still mostly focussed on internal issues and measure their success with GNP (or in rare cases GNH), which is essentially selfish on the national level, and so does not encourage progress with issues that are more global in nature. A good country is one that is not selfish, but one that does things that are good for the rest of the world. The encouraging thing is that being good in this sense is not a sacrifice, because a country with a good reputation attracts more business and naturally improves its own prosperity too.

So which country does most good for the world? The answer is in the The Good Country Index.

Sandra Aamodt: Why dieting doesn't usually work (12.5 minutes)
Rating: TTTT (140108)
The brain has its own idea of what your normal weight is. Maintaining your normal weight does not require a diet, only mindful eating: eat when you are hungry, refrain from eating when you are not hungry.

If your weight stays above normal for a couple of years, it becomes the new normal, and you can't adjust it back down. Trying to stay below your normal weight will be a constant struggle, because your brain will do what it can to restore normal weight, e.g. slow down your metabolism and make you more hungry.

On the positive side, as long as you maintain some good habits, you can stay healthy regardless of weight: eating enough fruits and vegetables, exercising 3 times a week, not smoking and drinking in moderation.

Above all in economic development, if people do not wish to be helped, leave them alone. The first principle of aid is respect. So what do you do? You shut up and listen. One-on-one.

In an increasingly interconnected world, individual nations can no longer keep their territory safe on their own. We need governance of the global space of power and this can presumably only happen through treaties. The strength of businesses and governments depends on their ability to network, so vertical partitioning (like the typical departments of today's governments) will not be effective. We are entering a multipolar world of power, which means there are more options for forming alliances.

Susan Cain: The power of introverts (19 minutes)
Rating: TTTT (120302)
"Western societies, in particular the U.S., have always favored the man of action over the man of contemplation." "Solitude matters. For some people, it's the air that they breathe." "We need teamwork to solve the world's problems, but the more freedom we give introverts to be themselves, the more likely they are to come of with there own unique solutions to these problems."

"Stop the madness for constant group work. Just stop it! Serendipitous exchange of ideas is good for both introverts and extroverts. But we need much more privacy, much more freedom, much more autonomy at work. Same thing in schools. Children need to learn how to work on their own, because that's where deep thought comes from."

Rating: TTTT (111020)
Love is not a feeling, it's a drive, a craving. There are three separate brain systems for lust (sex drive), romantic love and attachment. The two latter are controlled by dopamine and oxytocin, respectively. Serotonin-enhancing drugs (SSRIs) suppress both dopamine and sex drive, so they should only be taken short-term.

Rating: TTTT (110322)
We live in a world were it seems that the people and institutions we depend on don't have our best interests at heart. When something goes wrong (e.g. a financial collapse), we create new rules and incentives to make sure people do the right thing in the future. But rules and incentives demoralizes people and are not a substitute for wisdom. Fortunately, some people are "system changers", e.g. they figure out ways to break free from the accumulated rules so that we can apply our wisdom and good judgement to do things in a better way.

Brene Brown: The power of vulnerability (20 minutes)
Rating: TTTT (110227)
Connection is what gives purpose and meaning to our lives. Shame ("I am not good enough") is the fear of disconnection. Vulnerability: for connection to happen, we have to allow ourselves to be seen. Worthiness: the only difference between the people who have love and belonging and those who don't is that the former believe they are worthy of love and belonging. The reason is that
  • they have the courage to be imperfect (courage: cour=latin heart, to tell the story of who you are with your whole heart),
  • they have the compassion to be kind to themselves first and then others (it's the only way that works),
  • they have connection as a result of authenticity (be who you are),
  • they embrace vulnerability as something fundamental and necessary, and believe it makes them beautiful.
We numb vulnerability, and with it all other emotion. We make everything uncertain certain. Politics is just about blame nowadays. Blame is a way to discharge pain and discomfort.

Rating: TTT+ (100513)
Both the academic world and industry has a tendency to reward complexity, but it is simplicity that is they key to real progress. Simple things are reliable, predictable, cheap (high value/performance for money) and can serve as building blocks. It is only thanks to simple building blocks that complex things like the Internet can be built. Quotes: Everything should be made as simple as possible, but not simpler.

Rating: TTTT (100306)
"All is well that ends well.". Only a small fraction of our experience influences our memory of the experience. The last part of an experience is usually more important than the rest. The memory of a two week vacation is not twice as good as the memory of a one-week vacation, even if both weeks were equally good. To be able to measure happiness and make government policies that make people happier, it is important to understand the difference between the happiness of the experiencing self and the hapiness of the remembering self. For example, in the U.S. one Gallup study showed that the happiness of the experiencing self increase with income, but only up to $60.000 per year, while the remembering self is happier the higher the income even beyond that limit.

There is a mismatch between what science knows and what business does. For anything but trivial routine jobs, Autonomy (the urge to direct our own lives), Mastery (the desire to get better and better at something that matters) and Purpose (the yearning to do what we do in the service of something larger than ourselves) are better motivators and result in better performance than managers with carrots and sticks.

Alain de Botton: A kinder, gentler philosophy of success (16 minutes)
Rating: TTTT (090803)
Career crises. It is easier than ever to make a living, but harder than ever to stay free of career anxiety. Job snobbery. The opposite of a snob is your mother. Most people make a strict correlation between how much time/love/respect they are prepared to give you and your position in the social hierarchy. That's why we need careers and material status symbols (luxury items) even if we not necessarily materialistic. Someone with a Ferrary isn't greedy, but more likely vulnerable and in need of love. Meritocracy: people reach the top based on their merits and vice versa. This leads to more suicides, because we have no one to blame but our selves when things go wrong. But the justice meritocracy implies is impossible, too many things are random. About success: you can't be successful at everything. Also make sure you use your own definition of success, not someone else's.

In this talk from 2005, Larry Burns from GM talks about how GM is committed to creating the car for the future, based on hydrogen fuel cells. But GM had their chance already in the 90s, and they blew it. The electric car they created then was a success, and even though the lucky few who got the chance to lease one wanted to buy their car and keep it, all the cars were recalled and destroyed. After hearing Shai Agassi talk about eletric cars, and seeing the situation GM is in today, it seems pretty obvious that neither GM nor fuel cells have a future.

Bill gates is optimistic that malaria can eliminated. But since malaria has already been eliminated from all the rich countries, more money is spent on baldness drugs than on fighting malaria. Another equally important problem to solve is the U.S. education system. The top 20% students in the U.S. are better than the top 20% in other places in the world, but the difference is getting smaller. The remaning 80% are weaker than the rest of the world and they are getting worse. In the U.S., 30% of all kids drop out of high school (50% among minorities). If you are low-income in the U.S., you have a higher chance of going to jail than you do of getting a [college] degree. That does not seem entirely fair. Good teachers is the key ingredient in the solution to this problem. But good teachers aren't rewarded in the current system, and their skills are not spread. But KIPP schools are different.

And that's what we are doing to our kids, they live life knowing that they live it against the law, and that realization is extraordinarily corrosive, extraordinarily corrupting. And in a democracy, we ought to be able to do better
Michael Wesch: An anthropological introduction to YouTube
Rating: TTT (080906)
A very entertaining presentation that also is also food for thought. While the web started out by hyperlinking text, it is now linking people through the sharing of user generated content on sites like YouTube and social networking on sites like Facebook. Our politicians respond these phenomena by proposing stricter regulations, require ISPs to keep record all communication patterns and filter "illegal" content, when we really need to rethink things like copyright, authorship, identity, ethics, governance, commerce and privacy. We have to get it right, to save our kids from growing up in a society where they will be breaking the law every day, just by living a normal life.
Fredrik Härén om kunskap, del 2 (34 minutes)
Rating: TTTT (080427)
Fredrik Härén is telling us, in an entertaining way, that if we (the "developed" countries) don't open our eyes to the changes in the world around us (the "developing" countries), we will soon start to lag behind. For example, in Zimbabwe, which has been rated the worst country in the world to live in, you can pay your gardener by sending an SMS to his cell phone. When will that be possible in "developed" countries like Sweden?
