Having watched a good number of people take the course, I think it's still extremely difficult for most students with no background in the subject. A number of classmates from other disciplines have told me that it was the hardest they took during undergrad.

It was definitely altered to be able to cater to a wider range of students, but that was mostly done with more approachable lectures and a _huge_ amount of support from the course staff rather than by simply making it easy.

If you already have a programming background then it is definitely very straightforward because, at the end of the day, it's an intro to programming course.
I think that is true to an extent, as far as international politics goes. Saudi Arabia is happy to make that move to target say Iran, etc.

But things like oil sands and etc won't go away. It's accessible and the boom and bust nature of oil is just part of the system. They don't really stop oil sands.. just pause them.

Someone goes bankrupt today, someone else will sell that oil when the price goes back up. And if the price never goes back up then even Saudi Arabia is in trouble...

Of course. In context, I read "anything at scale does this" to mean "anything at scale dehumanizes its users" which is the point that I disagree with. A scaled-up service can still honour the client -- it takes intention and good design, but it's certainly possible.
It all comes down to how you ask the question. If you ask the question like this instead, the outcome is in my opinion slightly less up for interpretation:

Q: "What happens when a badly governed country, already ripe with corruption and tendencies of sectarianism and local warlords, loses its only real source of income and the economy collapses?"

> There may be local revolutions resulting in more democratic governments.

If we are to entertain this hypothesis, why has this not happened already in the general area? There have been plenty of chances, not only in the Middle East but also in war-torn countries in Africa. The answer in my mind is that armed forces are already concentrated in the hands of the corrupt, and in an environment where surplus is a generation away, power will corrupt the uncorrupted.

When state power collapses, the economy grinds to a halt and the most basic necessities of life can no longer be counted on, in a country that also already has armed para-military groups and tendencies toward sectarianism and warlord leadership, the outcome is predictable: it's civil war, and untold suffering.
Verifying Storage on Filecoin
Yep if anything I hope the Ambani family's escapades with Jio doesn't whitewash their deserved reputation as perhaps the most corrupt company in India.

For those not aware, Jio itself came into being via a scam. (That the comment I replied to is alluding to). The TL;DR is Reliance acquired a company that had only managed to win an Internet Service Provider license auction (that too in a dubious manner [1], [2])

Then Reliance 'convinced' the government to let them convert the license [3] to allow them to provide voice services as well, for a paltry fee (the amount they paid was set in 2001 and did not account for inflation over 12 years - which is pretty significant in India). Thus Jio was able to become a full blown 4G cellular provider at a fraction of the cost of competitors like Vodafone, Airtel etc.

Would they move from four physical cores (GX-412TC) to two and without even hyperthreading (R1102G)? I'm not convinced.

I've seen a few thin client manufacturers that moved to Intel Goldmont APUs such as 4c ~10W J4105 (Wyse 5040, Fujitsu s740). Interestingly HP continues to use a custom downclocked Carrizo in their t630 (GX-420GI, 4c, 16W).

My guess is PCEngines is gonna wait and see, as the four core jaguar is enough for what they need for now, and they care about the longevity of their product life cycles.
yeah I've noticed in Firefox Wiki.js appears to blank in between each page (doesn't happen for me in other browsers). This is very disruptive and has prevented me from further interest in the platform, sadly.
> But the users are all mathematical enough to want formal requirements.

This seems like a strange interpretation. I understand that the term "formal requirements" has a technical meaning in some disciplines, but I also think it's pretty clear that the author isn't using the term in that way.

It is much more likely that the author meant that users have requirements, but those requirements don't typically map cleanly to actions taken by the computer. This step of translation is necessary in the construction of a program, even if it is typically done piecemeal and iteratively.
Well, it's more severe now and as you pointed out yourself, it's becoming increasingly common. Not to mention a shift to renewables (despite some developing countries continuing to rely on oil), which may add increasing pressure.
Thank you for, perhaps unintentionally, proving my point.

Not OP, but I think it’s a general observation that a lot of the high visibility devrel folks tend to have fairly colorful personalities. This often extends to hair color. Charity Majors would be a good example of this kind of person (though she’s not in devrel).

So yes, alternative. Colorful hair, lots of visible tattoos, etc. A contrast to the sales folks, who are typically the opposite.

Allegedly a postscript was added to the first article referring to the facebook fact checking, so I imagine this is actually the original article and not the updated one.
Yeah, that’s not how it works at all (or has ever worked). It’s defined as a state machine and parses it code point by code point. And since HTML5, it defines how all inputs must be parsed: if two browsers ever parse any HTML document differently, there’s a bug in at least one of them. You can write non-conformant documents, but browsers will still all parse them identically.

Your example is equivalent to <div class="pants" shirts="" id="small">. This may show your error in expecting that it look backwards: no attribute names are considered special, an attribute value is concluded by its closing quote or by characters like space, and attributes don’t have to have values (there are plenty of boolean attributes, which are the most common cases where people omit the ="").

The HTML grammar really isn’t conducive to lexing.

If you’re interested in how it all actually works, I find how the HTML spec defines its parser very approachable.

You might sum it up as:

These countries weather boom/bust cycles in oil prices, waiting for a 'someday' to refill their coffers, and every year there are more and more things trying to put off 'someday' a little longer.

Essentially these countries have an antagonistic relationship with the rest of the world, as do quite a few corporations really. If you only get good news when everyone else gets bad news, then you've made an enemy of your customers. They just might know it yet. Lots of them will be working in an uncoordinated fashion to make their bad news a little better, making your good news worse and worse.

Once word gets around they'll start teaming up.
More specifically, it's range over time.

We made a recent long trip with our Tesla Model S, which has about a 325 mile max range. There were plenty of superchargers, but it takes time.

You also end up stopping a lot more than once every 300 miles, because the rate of charge up to 90% is very fast, but the last 10% is very slow. We usually ran down to between 50 and 100 miles of range, and charged it up to about 290-300 miles, which took between 15 and 20 minutes.

It's not terrible, but compared to a gas engine, it's a good bit slower over time.

On the upside, it forces you to have a more 'easy going' drive.

Are Facebook walls "private, personal conversations?" "Wall" implies they aren't.

Mechanically, they clearly aren't; they're passing through Facebook's servers and FB doesn't pretend to treat them as unfiltered content (in fact, the feed algorithm complaints are much older than the fact-checking complaints).
The problem in the linked article doesn't seem to be that the rules were ambiguous. Instead it seems as though they were perfectly clear but overruled by leadership because of external pressure. Plus there's this:

> Last week, however, ProPublica reported that explicit misinformation about voting remains rampant on the platform.

Voting misinformation is not ambiguous in the way you describe, yet Facebook doesn't care.
Yes.

Usually that concept in that quote is a baseline of demand. The government will accept tax payments in US dollars, but they will probably demand no BitCoin, stamps, bullion, etc.

That said, tax payments are not the only type of demand.
Hi Edwin. Will you guys ever add the ability to "pause" subscriptions? The only way to do that right now is to resort to various "hacks", such as adding a 100% discount coupon and then taking it off when unpausing.

This is just plain wrong. Currencies have value themselves for their utility as a means of exchange, not because of taxes. This idea that raising taxes increases the value of a currency is bonkers.
No, I was being vague and you are basically correct: I really meant "occurring due to a static abberation in the brain present since birth / puberty / adulthood", like schizophrenia, bipolar disorder, many forms of depression, versus something that can be induced by circumstances or upbringing. Making it more vague is, for instance, that PTSD is obviously "induced by circumstances" but is also thought to be due to a brain injury caused by emotional trauma.

Scientifically there isn't a boundary, and I am speaking very loosely here and probably should have said something more specific.

But "all thoughts are physical things happening in the head" is perhaps too reductive, similar to saying "all physics is quantum mechanics" - just because it's true doesn't mean it's a useful way to think about a specific problem. There's a distinct medical difference between someone with chronic depression without a specific life event ("neurostructural"), and someone who started out being "legitimately" depressed after being laid off, but spiralled downwards. Both can be described as a "deficit in the structure of the brain" but in the former case that structural deficit likely cannot be fixed by the brain itself (even with the guidance of a therapist) and drugs are probably necessary. In the latter case, perhaps only CBT and general wellness habits are enough - the brain can fix its own "structural problem."
That’s fine with me.

The iPhone SE was a good size but had terrible battery life from day one.

I’m now using an iPhone 7, and it too has terrible battery life, with the added benefit that if I take it out of its case I cannot hold on to it for a sustained period because it’s so thin and has no real edges to speak of, just large diameter radii.

I think states could produce such quality lessons, for free. The ROI of these would be enormous if proper internet access given to schools and households.

Why have 10.000 poor versions of a lesson accross the country instead of teachers or parents guiding classes based on curated, great online classes?

That's true, one must also account for the carbon footprint of the inputs. Of course oil extraction and refining also has a carbon footprint.

> vulnerable to confiscation from foreign governments if they decide they don't like your face

This should be a sign that the rule of law is in decline all over the world. What UK did and the US is doing is completely absurd, even when dealing with an authoritarian regime. Not only UK is holding gold that is not owned by them, but it is giving that gold to a pirate designated by the US.

And this is bad not just for the particular case, but it may also be used as precedent for similar illegal actions against other governments that don't subscribe to the US gospel.

I'm not going to defend Dubai but regarding oil being dominant to the economy.

I question how realistic it is for Saudi Arabia to turn into anything like the "tech hub" or "international finance center" or whatever of the area while simultaneously being an Islamist, conservative theocracy that is in many ways still judicially medieval.

Even if they pull it off, many people will think twice about coming there. Corruption, bigotry and a close-minded view of the world needs to go first.

Look at a country like Singapore: does anyone believe that they would be where they are today if they were an authoritarian regime that executed homosexuals and ordered the murder and dismemberment of dissidents abroad?

Oil money comes with strings attached and to completely ignore this in your analysis seems either uninformed or disingenuous.

So called Petro Dollars, for example, can't be just spent on anything. It is so difficult to dig up information on this (which was US state secret for a while btw) but iirc KSA must at least spend a portion of "their" Dollars on US treasuries. Another portion of "their" Dollars must go to US arms manufacturers. In return, US backed (formerly UK backed) Saud family gets to play King in Arabia.

So that "leadership that is too busy feating off" is aka Puppets of Western imperial colonials cum American hegemon's vassals. Any efforts by locals to denude themselves of the said "leadership" is not looked upon kindly by the "interantional community".

I would wait until they get field trials and do a launch in India (which is what Jio plans anyways). I think if they can do it at India scale and complexity - they can pretty much do it anywhere in the world. India scale is obvious - large geography and relatively dense population. Complexity because of unreliability of basic infrastructure (like guaranteed power supply, people digging over your network pipeline etc.)

I am usually a skeptic when it comes to claims made by companies in the Indian context, for example, my Jio connection is spotty at best in tier 2 city and very much a PITA if I go in the rural areas where the state owned BSNL is still the winner.
Is he wrong, though? The US, Chinese and Indian models have a fairly strong vision for their internet ecosystems. What's Europe's, and who benefits?

From the outside, the EU's big swings (GDPR, Cookie Law, Article 13, etc) look like reactionary messes, and it doesn't seem like their current behavior is doing much to help their companies, governments, or citizens.

Jio’s offer is really good on paper, but it’s got to be one of the slowest 4G networks I’ve used when I tried it in February. Anyone know if this is because of a lack of competition (there’s effectively one other serious player left in the Indian telco market right now), or capacity constraints?
Exactly. Many people I know, myself included see the 'investments' being routed to Jio as buying assurances from the government that regulations like data localization and other pro-privacy, anti-west measures are halted or watered down. A shakedown, in other words.
Show HN: Journal Together, journal with your friends over email, for free
Hey HN! I wanted to share Journal Together, an app I made recently to play with clojure and scratch an itch:

Context:

I started a company with my best friend, and we decided to share a journal with each other. We started off using Paper, but I thought it would more convenient if was over email: we already use email, and it would be handy if we were reminded.

I made a barebones version for us. We soon decided to add a few of our close friends: many of them live in different cities, and we thought it would be a good way to keep in touch.

It's turned out to be a blast so far. Here's how it works:

1. You sign up, and invite your friends

2. At the end of every day, you receive an email, asking about your day

3. The next day, you receive a group email with your friends, with what everyone wrote.

It's free to use : )

Some technical notes:

Clojure has been a pure joy. Some reflections on building it:

* The REPL made working with webhooks _much_ a breeze

* I could capture requests and replay them over and over.

* Clojure interop + JVM is a superpower

* Lib ecosystem def saves the day: java.time may be the best time library I've used. It was great to use Stripe's lib too.

* B/c I could use threads, I could avoid introducing out-of- process queues for scheduling.

For the db, I tried to stretch firebase:

* Firebase's client side abstractions are best in class

* Their database on the client abstraction masks a bunch of complexity: from optimistic updates to offline mode.

* They _are_ extensible: i.e with custom auth

* The downsides were painful:

* Rule engine is weak: as soon as you start writing more serious rules it gets out of hand. I almost created my own DSL

* Query engine is weak: Many to many relationships can't be managed without de-normalizing the data.

* There's room for a startup here ^

> We need an internet that works for its citizens and members, and on that front I have still more trust in the old continent

I broadly agree with the spirit of this line. But I fail to see how Europe is achieving that. Can you share a few specific (and meaningful) examples of how European approach has created an outcome which works better for its citizens and members?

So far from what I have seen, European companies (eg. Spotify) seem to have a similar modus operandi as their US counterparts. Many European countries are still in NATO and hence would collaborate with the US government for security purposes when push comes to shove. And the key regulatory initiatives either haven't proven effective in curbing US giants' powers (eg. GDPR) or have pretty strong counter-arguments rooted in principles (eg. Right to be forgotten vs freedom of speech).
