this comment largely assumes you know how to create test harnesses to sanity check your code.

from my experience, while glibc checks are useful, you need to know about more cases such as overflows, overruns, races, etc. In my experience, I used valgrind withub a test harness to create the conditions i'd expect.

The glibc approach doesn't seem to compete feature wise with valgrind. It seems to me that glibc bloat is caused by this.

PS: I have ran valgrind in production, You just have to carefully canary it.
You mean like how every U.S. Tesla ever sold has been heavily subsidized with tax rebates? And how they actually got a U.S. Government loan? And how they got further tax credits from Nevada for building the Gigafactory there?
that's why people don't really want to debate. A thinks B is brainwashed. full stop. There is no debate.
actually, just checked. The website is published with github pages from https://github.com/gabipurcaru/dedo/. For the geeks out there, this bit of code should be interesting: https://github.com/gabipurcaru/dedo/blob/master/lang/src/uni...
You don't even have to do the dumping. Venezuela gov's own program for better food allowed Venezuelans to purchase food from neighboring countries for 'cheap.' The result is that a lot of Venezuelan farmers closed shop during these good times.

Alas, cue hard times, and you have today (or these past ~3 years).

(This is a terrible simplification of Venezuela's ills, I only say it because it is an interesting case where internal food aid did the same destructive thing. It seems if you want lasting food aid, you should always try to make the aid bottom up, from the farmers.)

For reasons that are mundane, I started college at 24 without any math foundation. I did a full year of remedial mathematics as 0 credit courses, and by the end of that, I was prepared for pre-calculus, the first course with credits for an undergraduate degree.

From there, a bevy of other math classes - Differential and Integral Calculus, Math Proof, Combinatorics and Graph theory, and many half-math, half-something classes like physics, regular expressions, and everything between.

But all of it was based on the foundation of that year of 0 credit courses. At the time it seemed like a risky, almost foolish gamble, but in hindsight it has paid off several times over - by that I mean I have been able to pay off the entire college tuition, several times - there is zero doubt that it was a good move, for me, at that time of my life.

I encourage anyone facing the uphill journey of (re)learning math to take a deep breath, make an itinerary, and sleep on it. And if you decide to start that journey, don't go alone: Resources exist along the way, like Interstate rest stops, to help you recharge and get ahead. Remember, that a tutor is also improving themselves as they teach you, for each time they learn a new way to explain a concept, they too gain from the experience. It's not a charitable action to receive extra help learning math.

As you continue, you will possibly feel inclined to pay back and tutor those following. You too will rediscover the path and improve your math foundation as you are generous with sharing your perspectives and techniques.

Good luck! It seems like it will take forever, but is over before you know it.

The modern doctor is far more productive. She's healing 10 highly productive units.

In fact I think that could generalise for all service based work. Providing a service enables people to not have to do the thing themselves. As such the productivity of the service can be considered a factor of the productivity of the people they are providing the service for.
Right, that's the point! The low pressure would make it very very inefficient, and you would actually need a heat exchange system far larger than earth reactors. We use liquid cooling in our PCs because a smaller heat sink can pump out more heat if it's going into liquid (for a fixed flow rate). This is why liquid cooling for CPU/GPU setups is quiet and effective: the liquid flows quietly and carries heat to a BIG, slow fan. Your fan and heat sink would be even bigger/faster at Mars atmospheric densities just to cool your puny CPU. Doing that at scale with no water cooling for your reactor would be absurdly materials intensive.

That's all for a typical high-power reactor setup. You can, of course, have a low-power setup with nuclear power. RTGs [1] use this approach, though they mainly rely on decay heat rather than self-sustaining reactions, which is just as well because they are also thermodynamically limited by the rate at which they can radiate heat away.

One addendum I should have noted: the efficiency of a thermal engine on mars would actually be perfectly reasonable for a small engine (it's nice and cold there, perfect for high efficiencies). The issue is that you can't dump the heat fast enough, so your heat sink will get hotter, trashing your efficiency and reducing your cooling capacity (both of which exert downward pressure on your final power output in a serious way).

> Since the 1980s, cognitive psychology has consistently established that recall is indeed better after reading (printed) text instead of listening to it, a conclusion bolstered by a 2010 study (David B Daniel and William Douglas Woody), which found that students did worse on a test if they had listened to a podcast of a scientific article on child cognition rather than reading it.

I wonder if any of these studies allowed the subjects to rewind. I skip back constantly when listening to audiobooks, because I zone out or get distracted. If you were to study my comprehension while taking away that feature, I'm sure I'd score lower than reading with my eyes. Conversely, if you had me read with one of those apps that shows you one word at a time, and didn't let me rewind, I'm sure I would score lower on that than on audio.
I have setup my reddit account to use the old reddit, because for the desktop, the old one is much better than the new one.

Of course. If Hydro and Geothermal isn't a option, then Nuclear power is the only alternative that can completly remove carbon emissions. Renewables like solar and wind will always need backup power, which today is either coal, gas, or biofuels (i.e. burn garbage or corn). There is no battery technology today or forthcoming that can power a modern economy overnight or over seasons.

There is no other alternative to nuclear. I find it depressing that neither the media, nor the scientific and environmentalist community is never straight about this fact.

By the way, here is the energy mix of my home province: http://live.gridwatch.ca/home-page.html

When it comes to reducing fossil fuel use for energy generation, outside of gas usage during peak times (and to backup wind deployments), we're almost there. Don't have to wait until 2060 or whatever like Germany was projecting after they closed their Nuclear plants. Don't have to invest in exotic unproven technologies. Don't have to wait for technology innovation to save renewables.
This is one of the privacy conundrums that we mostly have never come to grips with. There are a lot of things that would seem to be legitimately public records.

But there's arguably a big difference between records that you have to go to some county clerk's office to access and possibly provide at least a cursory justification for doing so and being able to click a few keys on your computer and skim through records for the hell of it.

Both are public at some level but one is not like the other.

This relationship to self worth is a big piece of it. Valuing competence in a company is a cultural value. It's not professional, it's basically a craft/academic orientation or aspirationally so. The products I have seen them release were exceptional in their novelty.

There are upsides and downsides to the mysteriousness piece. The upside is rapid decisions based on group deference to demonstrable expertise and competence. The downside is a bottleneck where you can't delegate competence, so everything needs the guru blessing. Ultimately, this figure only gets a veto, and you get the global veto anti-pattern in the org. It's a basis for alignment that doesn't scale as well as dynamic collaboration.

To me, the quality of thinking part has an effect on the culture is expressed as the cost/benefit and scaling aspects of fast hierarchies vs. the optionality of dynamic collaboration. (viewed negatively as command/control vs. political solutions.)
Yes, gas still outputs CO2 but it's sooooooo much cleaner than coal in terms of everything else (and it's also cleaner in terms of CO2 per watt) that this seems like a solid win considering the lifetime over which power plants exist. It's not like this will be here for 100yr, they will get to choose what to replace it with in 50yr or less at which time we'll hopefully have good enough storage to replace the capacity of the gas plant with something greener.
Seem to recall seeing a documentary that said at first the USSR ignored the moon landing and once word leaked in, covered it in a very casual passing manner like one would a story about the wedding of a local politician. I do wonder if the genesis of the moon landing was a hoax story was some propaganda group within the Soviet government. If so, they got a lot of bang for their ruble.

I find it ironic that evolution optimized us for such effective energy storage because of constant food shortages, but now the same food and efficient storage is killing us.

As someone who is into fitness for the last decade I can understand many other people with less willpower to resist the hunger. People can give up drugs, alcohol, smoking, etc, because ultimately you don't need those things to survive, but we do need food to survive and it's so damn easy to overeat. Another bit of irony is that once you give up all those other unhealthy triggers of dopamine, food remains the (only?) main one, making it even so much harder to resist it, considering that apparently obesity is worse for your health than alcohol and smoking combined.

Better headline is “LA is reducing carbon output by 50% by replacing coal electricity production with natural gas.”

It will be funny when the switch from natural gas to solar in twenty years has a headline of “LA is finally ditching natural gas - and replacing it with another polluting fuel.”
I think you need to ask yourself why you can't overcome the issues you're running into. Are these problems specific to the software being developed or is it due to a deficiency in your programming knowledge? If it's the first read into how to work with legacy code bases. If it's the second practice programming some side projects. It's nice to have mentors at work and perhaps moving to another job that has mentors can help you get to the next level. But ultimately you need to learn how to figure things out yourself otherwise you'll always be dependent on someone else helping you figure things out.
I do not see that as a legit moral justification.

Not saying I do think it's morally wrong, just that these are beside the point.

In my lab its just another day at the office and with my suppliers and budget its boring COTS. To work with substance X, which is called "exotic", you need an upgrade beyond my lab's equipment and safety gear and training, my suppliers consider it custom work if they can provide at all, and the budget has another couple zeros.

More simply, its politely described as "exotic" if you go to a conference and talk about it and people are jealous of your gear / skills / budget / risk taking.

An electronics analogy is a dude who can't solder at all thinks thru-hole soldering is exotic skills and equipment. A dude good at thru-hole thinks SMD is exotic. A dude with good SMD ability thinks owning your own bare die wire-bonder is exotic. A dude with great wire-bond ability thinks working at a foundry and designing custom monolithic microwave chips is exotic. I have no idea what a custom microwave chip designer would think is exotic, probably some Area 51 stuff involving UFOs, realistically maybe working as a physical chemist or as an experimental semiconductor physicist. Those guys probably think super colliders and warp drives and fusion reactors are exotic, I donno.

Speaking of Beethoven string quartets, Michael Steinberg once wrote the following regarding a section from the Vivace of his late Op. 135 quartet in in F:

boldly and puts it down again on another pitch the way you might pick up your cat and move it from your favourite chair to another.

I am fully in favour of this feline-oriented musical interpretation.

Netflix Removes Controversial Suicide Scene from ‘13 Reasons Why’
"Hits" and "misses" should be thought of differently. Hits sell zillions and make people happy. Misses like the Apple Hi-Fi sell poorly because nobody wants them. So in the aggregate, there's far more good done when you have a hit, than bad done when you have a miss[0].

[0] Huge disclaimer: The category "miss" is higher dimensioned than "hit." Misses like the butterfly keyboard are different than the Hi-Fi, because it's a given that millions of people are going to buy a Mac laptop, and they suffer because they're forced to cope with an unreliable keyboard. By contrast, almost nobody is forced to use an Apple Hi-Fi.
Pushing Tesla more toward the "low end" was probably a strategic mistake. I think the "3" in general hurt their brand, and the "X" is an oddball in their lineup.

A better strategy would have been to have just the model "S" and a $200,000 roadster.

A friend of mine got his Los Altos High son a model "3" for graduation. The other kids make fun of him. "Couldn't you afford a "real" Tesla?" they say! Like it or not, the "3" is perceived as a compromise--not the real thing.

> Two AS355s serve as the video-copters, [...] An AS350 serves as a relay helicopter, equipped with VHF antennas that receive and transmit live feeds from the AS355s, as well as ground cameras on motorcycles.

> Circling at 2,000 feet (600m), the relay helo takes camera feeds and sends them to a fixed-wing aircraft flying higher at 10,000 to 25,000 feet (3,000-7,600m), depending on weather.

> The airplane sends the combined feeds back down to two receive trucks located along the race course. The trucks act like signal repeaters, the first sending video to a satellite that sends it back to the second truck further along the course, which finally forwards the signal to the town where the finish line is located.

> With stages of varying terrain up to 140 miles (225km) long, this hop-skip method ensures the best video fidelity with the least time-lag.

Knowing next to nothing about production video transmission, this seems overly complicated to me with several points of failure. I wonder how much of this article is editorialized and mixing up backup/redundant methods vs actual implementation?

The part about relaying between trucks using satellites seems especially strange, if the goal is to reduce time lag. Why are trucks needed to relay a satellite signal at all? Why can't the video-copters send direct to the fixed wing aircraft, or to the satellites? Why can't the fixed wing aircraft be used as a single hop?

If this is accurate, it makes me wonder how much of this setup is "we've been doing it this way for x years, and it works, so don't we mess with it" vs how it would be done with a modern, best-practices design. Anyone that's done this kind of work care to weigh in?
I have no strategy, learning just feels insanely good. Usually things I can't make sense of just get optimized away/drift into the ether and I don't care for remembering them (if it's important I will keep detailed notes of procedures, names etc at this point, but generally details/trivia don't cross my "care threshold"). <-- and honestly that is super important. It's just as much what you _don't_ learn, you know?

But things that change my understanding of a domain, let me contribute to something other people are building, or otherwise tell me how the world works?

Chances are I will spend hours non-stop talking about them relentlessly to anybody in range (or silently to myself) usually while moving, pace around so I can think faster, draw them, play around with problems that involve them, see everything in every domain as a manifestation of them for a while, and so on and so forth.

And apparently eventually it sticks. Like the first few notes of the song that was playing every morning of 8th grade or the color of grandma's roses. You can't fall in love with something for a while and then not think a little of it every time it's quiet.

I think this is an excellent point. The current emotional baggage with nuclear is stopping serious investment into this tech, which I believe has the potential to save the planet.

Gen IV nuclear is completely safe from meltdown, and some varieties can consume waste from previous generations, and yet most people (me included) have a visceral reaction to the idea of a plant being built near where we live.

Except if you go solar, then natural-gas comes along for the ride, because you need something that can backup the daily, and seasonal variability in solar output. This is why natural gas companies are one of the biggest lobby groups for wind and solar deployments.
