Is also worth a watch. Though I found that I've had to restart it a couple times over the years. Category theory, like many more abstract topics, is really hard to get a handle on. I've restarted those YouTube videos and have found them much easier this time around since enough of the basic category theory concepts are now in my head (though not fully understood with regard to purpose, implication, or application).

We've got Dr. Baez, Dr. Spivak, and several others who are much more familiar with the field and its applications participating in the forum now.

The lectures present the same material as the text book but in a slightly different order and with additional examples (what you'd expect from a lecture series). Technically, reading the lectures is sufficient for understanding the chapter at least at a high level. Reading both is fantastic because they complement each other (Dr. Baez assumes some of their theorems and propositions, but introduces others).
By this logic, it would be fair to say:

'When I get my paycheck, I earn my salary MINUS whatever "profit" my employer made from my work.'

This is disingenuous by ignoring risk and presupposing that (in this case) I have the same reach/clout/contacts/sales and marketing channels as my employer.
>had marx seen the soviet union at its prime he would have probably revised his own theory.

Actually I don't think so. Even Marx saw that socialism was a stage of history which followed from capitalism. In the same way that feudalism's aristocracy provides the conditions which create a merchant class that eventually overthrows the aristocracy, Marx sees capitalism and capitalists as providing the conditions which create a working class which eventually overthrows the capitalists. He would probably be annoyed with the soviets for trying to skip most of a phase and he would probably be annoyed with us, modern westerners, for not recognizing where in history we are - with rising inequality, increasing productivity but stagnating wages and the general increasing returns to capital.

>Marx's reserve army doesn't hold water.

Doesn't it? With chronic unemployment persisting since our most recent crash and now that we're finally reaching low unemployment ten years later, wages haven't moved much. If you explained the idea without mentioning Marx I think most people on the street would intuitively agree.
> To build an app at all he requires at least one computer, which is guaranteed to cost more than $99.

Well, the question is who does it cost? The original purchaser, or the person that was gifted it or got it for free because it didn't work and put the time in to fix it?

Plenty of people get computing hardware for free or close to it.

An interview with the author was in the Atlantic a few years ago:

https://www.theatlantic.com/national/archive/2012/09/a-septe...

This happened quite a while ago, but similar things are still going on today. Recently, I was considering a job in Pennsylvania, which unfortunately was several miles from the Marcus Hook Sunoco refinery (which has been in operation since 1902). It was recently fined $750,000 for "illegal modifications to equipment that allowed tons of potentially hazardous gases to be released into the air over two years." ...

"According to DNREC, the flare was modified at some point to receive gases from multiple sources throughout the Marcus Hook side of the facility, although no permit for those changes was ever sought by the company."

Those gases included hydrogen fluoride among other things.

I don't think this bit really requires much conversation, you can just read the relevant wikipedia pages for a quick rundown on things like the history of AOL, the internet, the world wide web and the seemingly nonsensical but curiously real distinctions between them over the years. What if you did that?
I guess that's how we end up with situations like http://www.insecam.org/

I think this kind of knowledge should be common, I mean, you should have a "network" course at school, learn how to forward ports and basis about how internet works.

Well, this is another discussion.
Sell Your Startup to a Breakout Company
Have you ever tried to ship 100 books? Last time I tried to ship 2 cookbooks across the US it was nearly $30 for just shipping. I would much rather ship a laptop and a power solution.

Not to mention the storage and care of 100 books in less-than-ideal housing where moisture and rodents are very real problems. Plus the actual volume of 100 some books.

Compared to a laptop, that can sit in your bag, and also serve as a light source.

It doesn't need to be a good laptop, it just has to be a laptop. There were still french farmers using text only BBS like terminals a decade ago, quite happily.

"However, for use as an antidepressant, 100-200mg (0.1-0.2g) twice a month is sufficient, so it shouldn’t be an issue. "

I will second that. A friend would use around that much and it would last almost 2 full weeks without feeling the need to take another 100mg. Once the 2 weeks hit though, he could feel his depression / anxiety coming back slowly.

> no growth + less revenue

I'd argue it's more like *slower growth, which should be acceptable, especially at Amazon's size.

Also, I'd in fact argue that making sure your employees have time to go pee wont significantly hurt your bottom line. At most you might need to hire a few few more people. Amazon operates at numbers big enough that this shouldn't be a considerable expense.
> The hardware was not designed in conjunction with the software

You're definitely right on that. The hardware took long enough to design, but the software wasn't even done when they started shipping.

> the resistive tablet

For people not familiar with the XO-1, it originally included a weird touchpad. The center third was capacitive, and would work with fingers. The Entire pad was resistive, and would work with a stylus (which was never shipped).

The dual resistive/capacitive was unreliable [0], and was eventually replaced [1] with just a capacitive touchpad with the same area as the original touchpad.

> the low-power-mode

This was a real shame to leave out. The OLPC XO-1 includes a specialized display controller [2] which can drive the display even while the CPU is suspended. THe idea is that the CPU would render one ebook page at a time and sleep between page turns. Unfortunately, the software for this was never implemented. All the rest of the hardware is there; it would have been really cool to have a near-zero-power ebook mode!

> several of the hardware buttons (including most of the ones next to the screen, which were mapped confusingly to arrow keys)

I'm not quite sure what you mean here. All of the keys on the keyboard are mapped [3]. The only ones I can think of which aren't used for much are the progressive dots (F5-F8), which are intended for application-specific use [4].

The buttons around the screen are mapped to the arrow keys (on the left side) and Home, End, PgUp, and PgDown (on the right side). I really like this, because when you fold the screen around into tablet mode, you can easily navigate a document. Reading a PDF or tall web page this way is a pleasant experience.

> the web browser and text editor were [...] standard Linux applications (Firefox and Libreoffice) [...] wrapped in their interface

You're right. The web browser is Firefox with a bunch of XUL stuff, and the document/text editor is AbiWord.

> The Sugar interface, as designed, had some very strange semantics

The idea behind an OS that journals everything you do with it [5] is great. All the power of a VCS, applied to everything you do on a computer. Unfortunately, the implementation in the OLPC is crude and severely hardware-restricted.

> development priority was to build a reverse-engineering suite

This is actually kind of funny, but the only mention I could find is in [6], which is a collective braindump page for software that would be cool to have on the OLPC. Do you have links to any discussion on this?

I've been using it on Android for a while. It's not perfect, but it's definitely good enough. There are still plenty of apps where I'd tell a CEO, "No, we really need three sets of client developers," but the number is certainly dropping over time.
It's not even so much about the rarity of events, but the violation of Informed Consent. The fundamental assumption in modern society is that you know there are dangers and their relative frequency, so that you may make decisions based on that for you to reach a mental equilibrium of risk vs reward. Someone/something acting psuedo-randomly to violate that equilibrium to an extreme (where there are brutally less choices available due to paralysis or fatal event for an individual or group) is what people react to. They want to incorporate these semi-random events into their daily equilibrium in the form of perceived patterns. This eventually leads to more extreme views (some form of theoretical pattern that fits), in lieu of data.

It's actually worse than doubling. The nature of distributed systems means that participating in resources consumed normally triples resource consumption at least. I'm not aware of any approach to decentralization of services like Facebook, Twitter, etc. that would merely double it.

Your typical desktop or laptop has a lot of resources to spare. Your typical mobile device has none. Mobile promotes a client/server mainframe/dumb-term architecture for fundamental technical reasons.
I think I'll disagree mildly. In "slow" languages like MATLAB and Python/NumPy, often the most performant way to do computation is array primitives. So much so that the style becomes idiomatic over, say, for loops.

Quick heads up to everyone who hasn't apparently read the article: This case is from the UK, where the evidentiary rules are different. It wouldn't pass muster in the US as there is an additional procedural hurdle the prosecution would have to clear to establish that the fingerprint(s) at issue could have been reliably extracted from the image. If the image in the article is the actual image in the case, it wouldn't satisfy US guidelines for fingerprint analysis.
> Don’t make me pay you to make my app available to your users. My app enriches your platform. Without good apps, your platform will be abandoned.

I don't know much about the guy or his app but this sounds supremely entitled. I don't think Apple is in want of developers to make apps for iOS.
VSCode, as far as I'm aware, uses Electron and is great.

Twitter's React web application was so good on performance and hitting all of the marks I used the mobile native application for that I was able to delete the native application saving space, and "adding to homescreen" for like, what, a few bytes of storage?

Facebook I just use the mobile web app inside of Safari proper instead of installing the native app. It's a pain that I have to wait until I'm on my iPad or PC to use messages (I don't install Messenger because I don't want a separate application just for a small feature of Facebook proper), but it's serviceable enough. Would be nice if Facebook would follow Twitter's lead and build a native-like web experience, but I guess they don't feel it adds the value and that's their right.

I'm completely game for people using these things and doing it right and if done so, yeah, I think it is better than or at least equivalent to native (PWAs != Electron apps, but can be served in them). It is also crazy to compare a 32GB-128GB device vs my PC with storage measured in TBs. I can afford bloat on my PC that I would prefer to keep away from my phone.
For my purposes? Very reliably. But my use cases are very sporadic; I'm just exposing a webhook for my VCS and running when one of a small set of my personal projects are updated.

My primary concern with nuclear power is the human element. For which we have a long and well-demonstrated history of limitations that don't match corresponding requirements.

In other words, we are creating something human history -- as well as contemporary events -- demonstrate we do not have an enduring ability to manage.

As they say, we can't put the genie back in the bottle. But we can perhaps do something to limit scope, particularly where alternatives are developing that are safer and, sliding down the development cost graph, more cost-effective.

P.S. I'll add that, until we can manufacture elements (more fully), I prefer to keep these limited resource available for potential future use, when we have acceptable alternatives -- for me, now, meaning solar, wind, hydro (all forms of solar energy, essentially).

Who knows what need we might have of them, in the future? What if really going to space requires them in significant quantity, but we burned them all up on street lighting and casinos? ;-)

(Wouldn't it be ironic if further sources were in space, but we didn't have enough to get there?)
Originally 21 produced hardware, which I imagine is a much more expensive industry to be in. That may have something to do with it.

The criticisms of the talk are valid, but overlook probably the biggest counterexample to the (cool) tools presented here:

Tableau.

Its dominating many areas of data analysis, yet the terms of service prohibit any scripting or API access to the formation of the XML that compose the .twb workbooks. The user is limited only to GUI clicking, none of which can be stored.

So I think its fair to say "You Can't Do Data Science in Tableau," even though its a useful tool and well implemented as a reporting tool. To me it seems a bit of a trap to build proficiency with Tableau and get locked into a closed enterprise product, I'm seeing a lot of data engineers at my company getting sucked into what is essentially a "tableau developer" role.
Has anyone unlocked a phone using a picture of the owner's finger? That would be neat!

She also told me that a couple of her other coworkers got fired the same way, and she and a couple of her ex-coworkers were talking about how it's something Amazon does periodically. Apparently that's how they cull people management doesn't like if they don't have a real reason to fire them.

I agree with the general thrust of much of this piece (and was shocked to read that he essentially classified these types of things as WMDs, just as I did for mass hacks of autonomous systems) but I will disagree with one main point.

I see no reason that humanity is worth saving over some other, better form of life. I'm not saying its ethical to mow down innocents to make way for the next generation, but some humans are pretty fucking awful. If our descendants are robots with the intelligence of Hawking and are full of kindness and grace then why should we insist that humanity exist forever? Even if we extinguished some of our evil impulses, like genocide and rape, what makes us better? My late aunt had Down syndrome but if I could invent a vaccine that stopped it from ever happening again I would even if I never harm someone with Down syndrome.

The best counterargument I can come up with is essentially the robots asking "What else is there to do?"

In some post-singularity paradise the robots can be heading in all directions at near the speed of light, but once they've figured out this universe's physics and ended armed conflict then it stands to reason that they'd end up creating or simulating places that did not have god-like creatures.

I think we might depend on the resource constraints and conflict to give our lives meaning. Kinda a riff on Eden's "knowledge of good and evil" a creature's intelligence and wisdom may depend on a universe of consequence.

As a user I am glad Apple is the "loser" in this article and it's the reason I love iOS and hope Apple doesn't change anything in their attitude towards the "free and open" web.
I do not trust the web, at all. Access the camera? Nope. The microphone? Are you kidding me. Notifications, GPS, background processing? Fuck no.

I am very happy to have Apple as a quality, security and privacy gatekeeper, because I do not have the time anymore to do that all by myself (and related to that, I'm so happy we've left the Windows era behind and I'm not bothered by friends and family anymore with all the crap and problems on their devices thanks to all the "free and open" stuff they'd download and install).

PWA's? Screw that, I hope they never become a first class citizen on Apple's platforms. It's good for Apple's business and their users to keep it that way.
All these licensing concerns exist in developed economies.

In third world countries like mine (India), the government produces text book content, prints and sells the books at subsidized prices. Stationery items are totally untaxed. If you look at the link I provided, you will realize that the most expensive textbooks in India cost about $2. $100 will buy 5 years worth of books for a student. That's much more useful than a substandard PDA with wifi.

India's explosive growth [1] followed electrification, not lead it. [2] It's 'intractable poverty' following WWII was only 'intractable' because of colonial exploitation - the British Empire squeezed it for cheap resources, labour, and wealth (By forcing Indian markets open to imports, and by banning some forms of local production - Gandhi's salt march was an example of resistance to that.) At the same time, the empire did not actually invest in the same kind of infrastructure that Europe enjoyed for close to a century.

China's a bit of a different case - but for contrast, compare it to the USSR. Despite three decades of war, civil war, near-genocidal purges, and some more war, by the 60s and 70s, it has lifted millions of people out of a similar level of intractable poverty. Again, not on the back of its economic system, but on the back of industrialization.

It's hard to stay poor (Compared to world poverty in the 1800s) when you have running water, indoor plumbing, and electricity.
