I really don't think it is. The replies on that twitter thread I posted there, from a couple of days ago clearly indicates (or at least implies) that the people leaving the platform are most likely the people unhappy with Twitter India's right wing bias.
I used to operate multibeam sonar system on an oceanographic research ship. Getting good data from those kinds of systems is an interesting challenge.

The speed of sound in water is proportional to temperature and conductivity — which are approximately dynamic functions of water column depth and temperature (and time depending on the properties of the region you are in — the tenperature can change a lot over short time scales). You need to measure to measure these properties in order to obtain a sufficiently accurate sound speed profile to be able to trace the path taken by acoustic energy projected from the transceiver, off the sea floor and back to the transceiver. Inaccurate sound velocity quickly becomes one of the largest error terms in measurement accuracy. We computed sound speed profiles as often as we reasonably could — sometimes the science objective involved measuring these properties and we’d use data from those measurements but sometimes we were just transiting along and would draw from a supply of expendable bathy thermographs that we could use to make sound speed profiles periodically (but certainly not often enough to maintain accurate calibration all the time.)

The ship is moving and the orientation of the array needs to be accurately calibrated — shipboard MRUs are expensive and imperfect.

The water column is rising and falling and vertical position measurement accuracy is very low from systems like gps compared to horizontal measurement accuracy.

The ship is pitching and with many ship designs this can create bubbles which can be swept beneath the ship — a small amount of bubbles close to the transceiver head can absolutely overwhelm the noise budget of these systems.

I’d be curious to know how much data from ship mounted sonar systems are actually useable for large scale high resolution mapping. I believe the best teams that build high resolution global sea floor maps rely on satellite gravimetric measurements for baselines — and use very sophisticated algorithms to fuse shipboard datasets with the global gravimetry — which im guessing probably have to throw away huge amounts of information from the higher resolution shipboard systems ...
I agree with you but in the cases I saw I felt that the triggers were used to fix problems in the code more than being part of a consistent data strategy. I admire well designed databases but unfortunately there aren’t too many of them out there.

I think part of the problem is that there is still this huge chasm between good coding skills and good database skills. It’s hard to have both.

So appending '--typescript' is troublesome and not obvious? Like this?

react-native init AppName --typescript

That's it. I never knew in 2019 that adding an extra flag would be 'troublesome'. The description of your installation of a React Native and TypeScript project in 2018+ is greatly exaggerated.
If you build a large nuclear reactor, you get big-scale negative effects in case of its failure. Both Chernobyl and Fukushima were "mega projects" by their design based on controlled explosion. You don't have to build gigantic reactors anymore, they could be relatively compact and the effect of their failure is appropriate.
I don't want to reuse all these preachers about yet-not-existing-but-totally-superior-x-generation nuclear reactors, but as I understand there are already active reactors that are, unlike Chernobyl and Fukushima, already based on a reaction that won't cause an explosion and catastrophic effects in case of failure, instead they would just become unusable.
Also the number of victims of the Chernobyl disaster are exaggerated. And the 235 billion dollar price tag is taken out of nowhere.
The weak position of nuclear industry is the mining tho.

> A one-centimeter variation in altitude would result in a timing error of several hundred microseconds per day

Source or math for this? Because for any signal in the MHz range, I’m not sure I believe it necessarily.

Several hundred microseconds of a 150Mhz wave is several thousand cycles. That seems... questionable.

I did a check on a decibel calc with a 150Mhz signal and a 1 meter change was approx .01db... which is effectively undetectable to a real world application. Signal strength isn’t the same as propagation delay, I know. But yea...

I look forward to being corrected, but I can’t say that claim seems legitimate on its face.

EDIT: Nope. Did some probably bad math on this on my own, claim is very nonsense. Esp because the delta distance is in space where radio has the speed of light.
I think we're on the same page.

When inheriting a purist DDD project written in C#, I came across several... interesting... charts, including this one:

A lot of members of my team couldn't figure out where things were "supposed" to go (or what most of the terms mean) after weeks of working on the code, so they just started slapping methods anywhere and worrying about it later.
To be clear, I mostly agree with you. But:

> Will this effort make it harder to build public infrastructure in the future?

It might. Things like this are frequently invoked in policy arguments to claim public efforts are unnecessary or ideologically suspect.

Again, that's not to say this is a wrong-headed effort, but not being clear-eyed about the role of patchwork private efforts in public policy arguments is unhelpfully naive.
You’re right in a way. However, newspapers have to have all stakeholders in on it: politicians, big businesses (aka advertisers), readers (trust factor) and their own reputation (journalists, etc).

With bots, you can really be a nuisance with a little bit of effort.

Fukushima cleanup cost that much because they're trying to bring radiation levels back to natural background levels instead of getting them down to levels thought safe enough.

Nuclear power still saves billions in health costs by preventing air pollution deaths. Remember, air pollution from fossil fuel kills 4.2 million people every year... year after year. Chernobyl killed up to 4000 total, Fukushima will kill up to 1.

I sometimes feel like the only people taking climate change as seriously as it deserves are actual climate scientists. Many of them do support nuclear. James Hansen, for example, advocates advanced nuclear in his book Storms of My Grandchildren.
I felt puzzled by Reddit's redesign until I started using the mobile app. Then as I was just scrolling and scrolling infinitely, just seeing what it would offer me next -- THAT is when I think I understood what the new Reddit interface was likely optimizing for.

To be honest, I actually don't mind that so much. The thing that annoys me about Reddit is the whole ads-that-look-like-posts thing.
Procedurally-generated JSON can nest data as deep as it needs to to describe arbitrarily-complex data, but I'd usually consider it an indicator that a problem thought to be simple has overflowed the bounds of its initial assumptions when it happens.
One extremely humorous IPCC report mentioned that cloud cover changes are poorly understood, could massively increase or decrease warming feedbacks likely drowning out all other signals, but for the sake of the report would be ignored.

So much science-y science you just can't stand it.
Yes, and the fourth: "What should be done?"

The problem becomes when people roar in about 1 and 2 and then make somewhat outrageous demands for 4, without justifying 4, or often 3.

This is what upsets most people, I think, even if they are not clever enough to articulate what's going on. There's a motte of defensible science that pushes for a much less defensible list of adjacent social causes, and then any pushback on the conclusions is easily painted as being "anti-science."
>Just giving them a place to stay doesn't cure the root problem.
reply

I suspect that this is because the 'place to stay' usually comes with various strings attached. I doubt there are many homeless people who would choose to sleep under a bridge rather than in a bed (though not doubt there are a minority who would).
A nuclear accident is more like a terrorist attack, while deaths from other power sources are more like car accidents. Sure more people die in car accidents, but it does not have the profound psychological effect of a terrorist attack.

That's exactly the pro-nuclear point; it's far less harmful in aggregate, and held back by irrational fears.

I don't suddenly get sick from pollution from coal power.

You just get suddenly diagnosed with lung cancer, and that's somehow better because you can't say for sure that it was due to exposure from pollution. But overall, it's over 200,000 deaths per year: https://www.nyp.org/cancer/cancerprevention/cancer-preventio.... That's a whole lot of Fukushimas.

And even if nuclear accident caused as little health problems and death as the most rose tinted stories suggest, you still cannot run away from the fact that these accidents carry MASSIVE price tags. Chernobyl involved hundreds of thousands of people doing cleanup. It cost 235 billion dollars to do. Fukushima cost 182 billion dollars.

It's amusing how nuclear power is the one place where environmentalists start worrying about fiscal discipline. Amortized over decades of nuclear power, those aren't that expensive.

So the options are to cut social programs, leave them as they are now, or expand them. Which option would you guess has the best chances of helping more people?
Linux Desktop launchers are much, much worse I think, if only because .desktop files are among the stupidest things ever designed.
I'm not particularly an advocate for typed languages (my daily driver for personal projects is Common Lisp, which is mostly untyped), but I'm having trouble even understanding the point of view that "No statement is safe". If I had a system where the actual type of the expression "1+2" were "3 | Error" I would find a new system.

Code that doesn't read from unsafe memory locations, allocate memory, or perform I/O cannot throw an error. Code that does can throw an error. Some systems treat out-of-memory as fatal, removing one of those 3.

In some domains you don't want to know if the computation is happening locally or remotely, but IMO most of the time you do because pure computation cannot signal an error locally, but remotely it can. As you mention, distributed computing often runs in this mode, but distributed computing is an overkill for most problems; my phone is powerful enough to locally compute most daily tasks (even when it's done server-side for various reasons); my workstation is powerful enough to perform most daily tasks for 100s of people simultaneously.

No need for a group think that corporations are evil. HN just likes to tear apart any premise presented to it. There are plenty of instances where they tear into the argument that corporations are evil and argue instead that capitalism is best-no regulation or taxes needed.

Machine learning does rely on heuristics, it just builds the heuristics on its own. If it runs into an attack that doesn't use any of the attack vectors it's learned to guard against, it will fail.

Think of it like your body. It learns to identify viruses. Does that mean you're immune from novel viruses or new strains of the flu?

The reason for the MCAS hack was not any engineering wisdom but simply allowing them to build a completely different plane that they could claim was in fact the very same plane, and then sell it to airlines as such. While the aircraft manufacturing industry was decades ago heavily safety-focused, this oversight was possible because the FAA has resigned its regulatory powers to the industry's own "self-regulation".

I have yet to come across a normal friend who doesn’t think HN is a super ugly site which essentially means if they had interest in the site, they prob wouldn’t use it.

I don't think it's unfair at all. Not everyone needs a place to live: some college students just live at home for free. I had some friends like that when I went to a major state university; they just commuted from home. They certainly didn't need to pay for a dorm or a meal plan because they lived off-campus, and luckily that school had no requirement to do so. Personally, I think they missed out on some of the "college experience" doing so, but still, I can't deny it was a lot cheaper for them.

On top of that, if living in a dorm and eating crappy cafeteria food is much more expensive than living off-campus in an apartment and getting your own food from a grocery store, I think it's fair to include those mandatory costs into the "cost of a university".

Your approach is not evidence-based and apparently has little or nothing to do with your publication history, which from what I can tell largely consists of studying behavioral interventions for diabetes prevention (which is an important area!). You are abusing your credentials in order to sell snake oil, and there's no way you're not aware that you're engaging in quackery.

"because charitable giving is dumb" is one of many possible reasons you were downvoted, but not the most likely.
Yeah but learning or completing tasks give a bit of dopamine so maybe learning in short bursts becomes addicting through successive iterations.

When you work, you have large tasks, you break them up into smaller tasks, you learn along the way, and you get fueled by dopamine to continue. You learn and use your knowledge to work through tasks that are standard and dynamic in terms of change. Easier to do large projects/tasks by breaking it in small tasks rather than one big task. Lots of 'getting things done' or todo management plans gamify the dopmamine hits into small tasks. Each task can remove or add more work depending on how you complete them or how much you think about them to optimize or reduce work. There is weight to each decision but also forward movement and tasks being completed which gives dopamine.

With online communities you are both learning and teaching on each iteration (comment/post) which when you post is a task being completed. The process is pretty standard and easy to repeat and focus on your points. The learning part is new information you get, the teaching part is formulating your response and refinement. Repeated actions like this refine and polish your ideas and understanding of the world. All of that is probably a dopamine hit combined with a bit of social aspect that may increase it. The impact of that task is low so it is easy to attack repeatedly, much like an addictive game cycle. There is little weight to each decision but also forward movement and the appearance/feeling of tasks being completed which gives dopamine.

When you are sitting in front of your big project with all the tasks and smaller tasks that have real impact, next to the addicting short burst communities with all sorts of new and old ideas and discussions from learning about space or politics to jokes and memes with low impact, the online communities/information/learning can outweigh your work/project as the former seems to become a bigger draw if you aren't careful. It is almost easier to feel like you have been doing things posting on reddit/HN until you break out of a focus state and realize that is taking from your work time, but easy to slip into due to the amazing breadth of information and topics, where work is just focused usually.

Both situations your brain is probably in plasticity states and getting dopamine from the learning and teaching short tasks.

It is probably best to have multiple projects you are working on one serious and one with more open creative mode so that procrastination is at least on work during worktime and addiction to distractions is limited. Creating addicting game cycles to give dopamine hits and repeated addictive cycles is very evident also in social media or online discussion, like the little reddit notification. You can easily go spend 15 minute breaks from work and end up hours into a reddit/HN/social discussion.

The plasticity of the brain in internet discussions also has our mind in a receptive state, so that is why online misinformation/disinformation is probably so able to propagate as well. The brain is open to new information and marketers/propagandists probably love that state to manipulate.
I think this is a positive development, but to me it highlights how sad it is that so much of America sees investment in its own people as "wasteful spending."

Protecting the most vulnerable people and ensuring people don't fall into the trap of poverty is an investment that should occur at the governmental level. There are many such governmental investments that would alleviate serious long-term problems.

My biggest frustration with the American government and American business-oriented culture in general is a lack of long-term thinking. We know that "a stitch in time saves nine," but instead we decide to go the nine stitches route. Put more nerdily, people do not properly respect the implications of exponential growth.

All existing nuclear plants that are running or could easily be made to run should be nationalized and brought under control of the DoE.

We need them all for base load. But new ones should not be built, we simply don't have time and the resources should be better spent on a massive increase in solar and wind.

Batteries, hydro and pumped hydro can follow the demand curve, nuclear should be viewed as strategic.

Solar is so ridiculously cheap and easy to run, we should drop a trillion dollars and build as much as we can, as fast as we can.
