Collecting quotes from the article: "'Some people [mindfulness] helps, some it can make ’em feel worse. ... [T]hey don’t listen to us, they just tell us to do mindfulness.' ... "Sharp, eloquent, indignant, the students explain what does help them when they are stressed or upset: talking to people they trust, being listened to, having fun. ... They have many ideas about what their school can do to help them, but it seems like no one is listening."

Generally speaking, if you're in a bad environment, getting more in tune with your feelings and how you react to your environment can make you feel more acute pain. Conversely, becoming numb and unaware of your feelings can help avoid the pain, and possibly help you remain more functional, at least in the short term.

Of course, pain tends to signify a problem that has significance beyond the pain itself (pain for pain's sake would seem to have negative evolutionary value, but e.g. pain that encourages you to avoid sharp objects has positive value), so ignoring it seems like a bad thing in the medium and long term. However, if you have no practical options for fixing the underlying problem, then it may just be pain without gain.
No. Optimal altitude for an EMP attack is actually a few hundred kilometers up. The "base case" usually considered in these scenarios is a nuke going off about 400 km over Omaha. At that altitude, the ionosphere helps you create a "slow" E3 pulse which induces a field in the tens of volts per kilometer at ground level; and since you can see most of the continental US, you have plenty of kilometers to work with.
This article is a bit misleading. He didn't just have a boring job, they wanted to fire him but because of the labor law in France they couldn't easily do this, so they gave him nothing to do as a form of harassment to try to get him to quit (more details here: https://www.theguardian.com/world/2016/may/02/frenchman-take... - he was "mise au placard"). This is similar to what got France Télécom in trouble for.
Can't say if this is the case, but due to harsh laws when trying to fire employees in Europe (sometimes having to pay years of salary), companies are known to use this tactic to get people to quit.

My mother worked in a bank and even 20 years ago I was told by her stories of some employees been assigned a desk in an empty room and pretty much no work until they quit (this was the time before Facebook and even phone/internet at work, so you didn't do anything else but look at empty papers/walls)

If psychoanalysis has taught us anything, it's that if you're the tiger, it doesn't disappear until confronted.

Recent years has also seen an increase in studies surrounding the sociological concept of `Mobbing'. This has taught us that the tiger only goes away if there is outside help, often in the form of fellow students, teachers, and so on.
Interesting, why open source is important for you?
What are some of the great insights that you got from your heatmaps?
For example, I found that replacing animated user images with real user images in testimonial section has increased the attention span of the testimonial section by 3X. Looking for similar insights?
It's not the external events that are the problem, but the way one reacts to them. Healthy people simply deal with their problems keeping more or less positive attitude during the process. The moment you start getting into a downward spiral of retreat from life, sabotaging oneself, having a "crisis" twice a week - you know you need to start digging, because your emotional configuration defines you as not prepared for dealing with the world. Every form of walking in circles for a prolonged amount of time is the same thing.

Psychotherapy. Definitely.
So your point is that if you take the output of the _same_ 128bit hash function twice, split it into 64bit parts and then put it back together, you still have the full properties of the 128bit hash function? Well, no shit.

I have to admit that I'm not the greatest cryptography whiz, but I can't image that this holds up for _independent_ hash functions, where you should be able to more cheaply run a preimage attack against two 64bit hash functions than one 128bit hash function.
To explain why that is: In SVG everything has x and y coordinates relative to the SVG view box. There is no fundamental declarative layout like in HTML/CSS where the browser will calculate where elements go for you.

SVG is great as something to embed in HTML, but not the other way around.

>> As Jack, a 13-year-old student at a school in a post-industrial town in the UK, explained: ‘They’re trying to teach us to choose what we want but then not letting us choose anything at all.’

Students are very quick to see through their teachers' bullshit as they have years of practice by the time they are adolescents.

The current convention seems to be that if students can't life-hack their school then there must be something wrong with them. That lack of self-reflection on the part of teachers and schools is telling, and probably a big reason for student anxiety in the first place.
I'm going to argue that it wasn't team sports, it was the infrequency with which you played them that caused the negativity.

Working as a team is part of the human experience. Some people are more inclined to it than others, but given enough time and frequency working with the same unit, almost everyone becomes a comrade, a brother-in-arms, bonded through shared experiences.

Team sports help develop social bonds and trust between peers, and those relationships help quite a few people deal with personal issues they would otherwise get stuck in their own heads trying to fight. Teamwork and working towards goals bigger than oneself are important to the psyche.
The company I worked for before ~ 8 years (a bank) was using Appian for a bunch of its non-core workflows and actually was in the process of using it even more.

Appian is a strange beast: It's a BPMS written as a Java web application that has an in-memory kdb (the db of the K programming language which is well-known in HN) for storing all process data.

The greatest advantage of Appian as compared to other workflow systems I've used (Activiti, jBPM etc) is that it offers a really complete environment for creating a more or less complete workflow without the need to write code. So you can actually teach non-technical people to do it. I remember we had a couple of Business Analysts that were creating very complex workflows back then. The didn't have any technical knowledge; their background was mostly on economics. Of course, for integration with legacy systems or relational databases or doing some tricky UI you'd still need a developer. But most of the work could be done by a not so tehnical guy which is the holy grail of such systems. Also, it was a really complete system where you could rather easily implement all your workflow needs (workflow design, user tasks, notifications, exceptions, integrations, reporting, authorizations, business rules, subprocessing, parallel execution etc). After some initial configuration you'd rarely need to touch code unless you needed some custom bpm nodes.

Appian was also claiming that because it was using the kdb as a database backend it was very fast. I don't have an opinion on this; it wasn't slow but wasn't blazing fast. And also when the kdb size grew too much (we're talking some tens of GBs) it was taking a really long time to start (half an hour or something) and needed the same amount of memory from the server (IIRC we had 64GB back then) because it needed to load the kdbs into memory. Also I remember that we had a constant fear that the kdbs will be compromised somehow (for example if the server rebooted unnormally) and we'll lose data. Or maybe I had that fear; I was never able to "trust" it as I could trust the good-old IBM DB2 database the bank had. Concerning data-loss, we had a bunch of incidents that were related to having configured appian as a cluster; after we switched to a single server it was better. The good thing (or maybe bad because I was never able to learn K) is that it had a complete API in Java so we didn't actually need to touch the kdbs; I remember with awe however when we had a support request where an Appian engineer was using K to actually query the kdb and see the status of our server.

In any case, the main drawback of Appian is how expensive it was. I don't remember how much but I remember that the bank had a special agreement to have a low price for Appian (don't exaclty now the details); buying it fully was too expensive even for the bank (!) (especially if it was to be used by all employees since it had a per user fee).

Beyond all these, I belive that Appian is a solid product and deserves its success in the enterprise world.

Actually I want to suggest this topic as well.

Modern breakthroughs for example Maxwell's Equation and Einstein's Relativity are both heavily relied on quaternion for their discovery. For Maxwell's Equation you only need one equation with quarternion instead of four separate equations as proposed by Heaviside!

The problem is that the majority of academics and scholars are still stucked with complex number, and they are the same people who are wondering why complex number concept was originally rejected by the academics and scholars when it was first introduced.
Alternatively if you dont want your keys stored in Authys cloud, you can replace Authy with AndOTP and export your keys in to an encrypted file which can be imported later back in to your phone when needed.
> That only addresses the one gripe I brought up as an example though, and not the general pattern. For instance another issue I've run into is this automagical hacks that parse fstab crypttab etc and make units at boot time, while not actually supporting all the customary options of those files.

Maybe the long term plan is to have these files dropped and replaced with something more systemd like?

> we're left with a hodgepodge of the old and new systems.

Same argument: if the long term goal is to completely overhawl the system, then at any point before that goal is reached there has to be old devices still in place.

That being said, I don't know much about systemd, not about the long term goals of systemd authors. I think that Poettering language of choice is C, so this explains that, but there's always room for other solutions in the FOSS world.
I didn't read the thesis itself yet but I feel like some key point must be missing from the article. The "loop programs" described are nearly identical to the "abacus machine" presented in the textbook Computability and Logic (pp. 55-56 3rd ed.) which cites Joachim Lambek who published "How to Program an Infinite Abacus" in 1961 which seems to also be trivially close in structure (not merely equivalent).

Lambek in turn cites Melzak's "An Informal Arithmetical Approach to Computability and Computation" which not identical - it has transfer and arbitrary compare branch instructions - but that seems a compromise for pedagogical purposes as deriving both from the "abacus" seems fairly trivial to me.
Sometimes, for whatever reason, people post terse comments.

When that happens, it’ll often spark a thread that then fills in the gaps.

Be kind. Don't be snarky. Have curious conversation; don't cross-examine. Comments should get more thoughtful and substantive, not less, as a topic gets more divisive.

Inoreader is wonderful.
AndOTP supports exporting TOTP secrets in to an encrypted file which can be reimported if you need to restore your keys.
You can have the file stored in Keepass or an encrypted container for storage.

Additionally it has support for Steam and Blizzard TOTP secrets. Though they aren't straightforward to use, its nice having them on one app.
Why would you make this responsive? It doesn't make sense for any games to have the map/board be different based on window-size.
People assuming things doesn't mean there is a pact, explicit or otherwise.

Isn't the whole idea of a social contract (which is what you describe, right?) of any kind debatable and really unprovable?

Couldn't one say it simply is a responsibility they have collectively taken onto themselves, on their own?

Of course, it doesn't change what will happen, what rescuers will do. Probably won't even change how they'll do it, or how they'll express their motivations from doing so.

So... how do you prove or disprove the existence of said pact?

Yes. Mostly they disable cmd-v/ctrl-v, but pasting via the context menu or the ‘Edit’ menu works.

In theory it's possible that they're trying to do some other thing by handling keyboard input on password fields, and that interferes with hotkeys—but I can't imagine what that other thing would be.
Stacked Pull Requests: Keeping GitHub Diffs Small (2016)
I think that the current world situation is going to be a large boost for VR (Virtual Reality). Before the pandemic I was much more in favour of AR (Augmented Reality) as a form of entertainment. VR requires so much more precision to get right and also (generally) prevents you from moving around too much in meat space. AR allows you to walk around an interact with things, which seems to be a much easier lift. However, with the social restrictions currently in place (and possibly going forward) the benefits of VR have outstripped its limitations, at least in my mind.

Picture this, instead of leaving your house to work (or go to school) you put on your headset and enter your work/school environment immediately. This solves the problems of travelling (time wasted, environmental impact, etc.) as well as being physically isolated. Most of this type of activity is performed sitting down so VR is a good fit.

It's not even particularity expensive or technologically difficult, especially if you work in an office job. Instead of requiring a large, expensive monitor (or multiple monitors) you can use a VR rig to have as many monitors as you wish. I can imagine being very productive in such a world. I'm already doing all of my inter-personal contact using video conferencing and VR would only make that better; I love the idea of not having to worry what my hair looks like or trying to remember not to pick my nose while I'm on camera.

I think education would see major benefits of VR, especially as you have to isolate everyone anyway. My wife is an educator and next year's teaching environment is radically different than previous years. The current plans include having kids staying in one classroom all day, reducing free time, no large groups for anything (field day, pep rally, etc.) However, if you embrace VR you can take the whole class on a field trip to every museum on Earth, dig deep into science (this Magic School Bus), or even meet with kids from other countries. This is all (relatively) cheap and easy to do.

This all said, there are definitely opportunities to make VR better and cheaper. Right now, it can be expensive on the individual level to get a good set up, but if you factor in office space costs the price looks more reasonable. Add in advances in light projection and head tracking hardware I think the price begins to plummet and the quality gets better and better.
Also wondering if this flow would be done differently in 2020.
It roughly does. Note that it is not present in the comparison chart you posted...

>The negotiations broke down because the Europeans have failed to develop as successful a digital economy and run a large digital economic deficit with the United States.

That is undeniably one aspect of it. However, I think the other one is that digital services have become a larger part of the world economy and they are structurally unlike anything that existed when the current rules of taxation were devised.

Traditionally, services required people on the ground and local subsidiaries that were subject to taxation and regulation. For instance, you can't run banking and insurance services for European customers entirely from the US. Trade in goods always benefitted from geographic proximity as well, even without tariffs.

A situation where you can provide services to a huge number of customers on the other end of the world without any local representation or taxation of corporate profits (or other income) is historically relatively new and does in my view justify calls for reform of global taxation.

>They want to levy a tax against an American import to help this trade imbalance, while claiming it doesn't amount to a trade tariff.

Claiming that trade imbalances as such are somehow unfair and need to be remedied is in my view nonsense, but it is an idea popularised by Mr. Trump himself.

You can't have it both ways unless you accept that mercantilist power politics is all there is and neither enlightened self interest nor principles play any role whatsoever. I think we can do better than that.
How did you arrive at this insight using a heatmap?

I stayed away from PE, for a couple of reasons:

1) The teachers were invariably bullies. They would belittle students that they did not feel “performed well.” Also, because of the nature of the class, this bullying could manifest in physical (not just verbal) form. PE was my “horror” class. I was terrified of it.

2) In the US, there is tremendous pressure to compete. Scoring is everywhere. I have never been a competitive person; always preferring consensus and cooperation. This attitude was highly discouraged in PE (often by nasty remarks from the teacher, and their “pets”).

3) I’m “on the spectrum,” and one of the manifestations of that, is rather poor coordination. I have never been able to perform well in any sport; no matter how hard I tried. I could get fit, but not good.

Sour grapes? Maybe.

But I do feel that bullying is a big problem in every society, and it is often done by the “winners,” so there’s no will to address it. No one wants to “hobble” their “stars.”

I don’t see how deep breathing exercises will address that.
Were you one of the kids who was good at sports? I remember school PE as being horrible for mental health. Anyone awkward, uncoordinated, unpopular, unhappy with their body, or just totally uninterested in competitive sports spent those lessons being ignored at best, shouted at at worst. Funny how in primary school we all happily ran about and played together at lunchtime, but enforced sports days and team sports made it very clear who was “good” and who was “bad”, and that those of us who were bad should just stay out of the way and not inconvenience our teammates. COMPETITIVE sports are obviously going to make those at the bottom miserable and foster resentment towards them: that’s kind of the point.

e: oh, and let’s not forget the horrifying combinations of changing rooms, showers and puberty... and for those of us with glasses there was a whole extra dimension of being forced to swim or dodge flying balls in the rain while literally semi-blind...!
Very common tactic in Europe indeed. The new thing is that now employees retaliate... and win.
How is this any different from what you have on your phone?

If someone hacks your phone they have access to all your email, whether you have 2fa set up or not. If someone hacks your computer in this case then they also get access to all your email.

The thing that 2fa is good at is preventing hackers from logging in if they guess or find out your password. If your device is compromised then everything you do on it is vulnerable, no matter how many factors you have.

I’ve always hated sports. No matter how much I tried, I was horrible. All my school stress stemmed from PE and sports, and with how much of a focus “coolness” in school stems from sports performance, pressure simply grew and grew until I finally graduated. After graduating, I actively rejected sports and fitness because I associated it with the people who were good and I hated to be around, and it was nothing but negative connections in my mind.

It wasn’t until a friend introduced me to weightlifting that I learned that I can not only enjoy exercise, but I can do it completely alone without anybody looking at me. A weight set and a bench to sit on are as close to meditation as exercise can get for me.

I’m stronger than the average person. Visibly fit to the point that people comment on it. But every time someone has expected me to catch something or throw something to them, it’s a disaster. People can’t believe it because there’s the association of fitness level == sports ability, but there’s as connected as math and programming. It’s definitely good to be good at both and they definitely benefit each other, but you can also be incompetent at one and good at the other. I’ve definitely known some people who’ve never cared about basketball and don’t really exercise but almost never miss a shot if someone asks them to try.
Note also the 'remove business for legal reasons' option. I imagine these get priority, and trademark violation and fraudulent misrepresentation is a legal reason.
That is an interesting observation/claim that TiFlash is based on ClickHouse. I’m not sure what benefits ClickHouse has over the ORC/Parquet based Open Source engines like Presto/Impala.

What is emerging in HTAP is two patterns: scale-up like HANA and scale-out like TiDB 4.0. The engine/system in both cases transparently handles the merge between the OLTP delta row store and the OLAP column store (AutoETL) and there is a transparent federated query that is aware of both store types.

Does Presto or another scale-out solution transparently perform these two HTAP functions?
Generally, /s in comments is shorthand for /sarc, a closing tag that indicates the prior comment is sarcasm. Thanks for being a good sport about it!
> Also, anyone who still can should print out Google backup codes and store them somewhere safe.

The 2fa set up process for many websites (and iirc Google too) do not make this a priority. They should clearly emphasize the importance of saving the backup codes, and make you check a box that says you printed them. The 2fa should not be enabled until that is done.
