Oh my gid, do you understand that these rockets carry Millions of liters of fuel? Thats the energy of a small nuclear bomb.

Unlike planes, they carry oxidiser and fuel, so they do not burn, they detonate. Minimal safe exclusion zone is measured in square miles!

Simpler? The fuel is chilled 2/3 of the way to absolute zero, and the engines are at several thousand degrees. Tiny manufacturing error and everyone dies.
Building a Marsbase is a Horrible Idea: Let’s do it [video]
Since "low-value flame wars" are already explicitly against the community guidelines, using that as the argument against notifications is like banning knives because they are potential murder weapons. And then having people defend that decision as a "good thing" that we can't cut vegetables.

> Thanks to Skip's tracking of side effects the garbage collector only has to scan memory reachable from the root of a computation

But any typical copying GC only has to scan memory reachable from the root(s) of a mutator. I suspect there are more interesting optimisations, but I am unable to discern them from this statement.
Physical book, highlighter, and pen for taking notes in the margin.
Sure. Since my main takeaway from the article is that it's propaganda click bait where the title and topic is to imply that the U.S. is in a strong position, particularly given the timing and related news of the day, I attribute the underlying intent to "someone at axios wants to write a fluff piece about the Biden admin". Yes, that might be what you call a conspiracy theory, OK. I obviously can't prove it absent commentary from the author or other Axios representative in official capacity.

But come on, really. Pretend it was Trump and Fox.

I'm guessing there are very few folks getting fifty miles a day in, and still heavily overweight. Possible, to be sure. Just very unlikely.
Sugarmate is a fantastic app/service that will call a phone number with an automated message if your Dexcom CGM falls below a certain threshold. It’s allowed my wife and I to sleep a tiny bit better knowing if our son’s blood sugar goes low that we’ll be woken up. Not affiliated, just a happy user.
6hrs a day @ 3 mph = 18 miles per day, 100 calories per mile without packs = 1800 calories per day on top of basal metabolic needs. Given your user name, I'd guess that you're male, and given that you're hiking the AT and have already started, I'd also guess that you're younger rather than older, so I'd peg your basal metabolism at around 2200-2400 calories. Add in the packs and the hills, and it should be clear why you're losing weight.
Copycat sites also used to be extremely careful at not appearing copycat sites. Or not duplicating content on the same site. I am surely not alone in recalling the old mantra of not duplicating content.

Copycat sites don't seem to care anymore.

I don't believe there are an overwhelming number for Google et al to deal with as it's often the same names topping search results that such filters can remove through semi-manual user action.

While leads to the conclusion - Google don't care about duplicate content any more.
Suggestion: don’t default the mood selector to “angry face.” Put it in the middle. My first glance at the page gave me the impression that all the news is horrible!
Created iOS investing app: predicts some stock direction with 70% accuracy
I created an investing app on the iOS App Store called Hubble (Easier to find if you search "Hubble Investing"). As a part of the app I created a couple AI's that can predict some stocks direction with >70% accuracy (Google and Amazon stocks are two of the best).

I think the app is pretty cool, but there is so much I can improve on. I would love if people would check it out and tell me what they think can be improved!

Mine enough to buy the environment, problem solved.
I don't think I have that misunderstanding. My question is, do you have proof that:

1. the CSPRNG in Linux is secure, and

2. CSPRNGs in general exists ?

Fixing #1 simply requires changing to another algorithm.

Fixing #2 requires a secure RNG to block for entropy, and if the distinction between /dev/random and /dev/urandom goes away, then this scenario will cause problems _if_ it happens. I said it's very unlikely, but I don't think I should get this uncharitable response by pointing out the issue.
Falcon Heavy was specified relatively early in the Falcon 9’s development cycle. They were originally going to do more Falcon Heavy missions but in the meantime, blocks 3 and 4 of Falcon 9 came out and the Merlin kept getting better and better, and with block 5 the Merlin D has almost double the thrust of the Merlins on the early Falcon 9s which is kind of nuts. So many of the missions conceived for Falcon Heavy were ultimately flown on a different rocket- a more capable single stick Falcon 9.
Airports do not have minimal safety distance measured in miles.

Catastrophic failure of a plane causes a fire, catastrophic failure of a rocket causes a detonation the size of a small nuke.
My title is software engineer II
Of course, I meant the idea of auctioning it off or otherwise accessing the customer’s data.

When I worked in Azure, I accidentally created some internal resources in a personal account. I didn’t have the ability to delete them after I left; the only way to do so was to cancel the credit card and let the grace period expire.
Cycling is roughly 5x more efficient than running/walking for similar effort. Thinking you will lose much weight by cycling is generally mistaken, unless you plan to cycle very long distances or are extremely obese already and do very little existing exercise (and this is discounting most of what TFA is saying too).
Great info. Fascinating.
So I'm not sure about everest climbers, 20k sounds pretty crazy.

But I can speak first hand as a former athlete who has had access to NFL players and Olympians. 8-10k during peak active training happens all the time

Long term average might be 4-5k.

You have to remember that these people are often on PEDs that allow them to train all day.

Shit I was a serious powerlifter back in the day and would routinely eat 6-7k calories (weighed) during 2adays depending on how my weight was fluctuating. Add some more height, PEDs, and cardio and I'm almost there.

I think the difference between what is mentioned in the article is #1 obviously PEDs #2 body breakdown and recovery, which might be more in e.g. lifters and swimmers than long distance runners
> Dunno where this claim comes from, but the author literally spent 1 day on their app lol.

So you did not read the article. Got it.
I think it would be odd if NYT bought Wordle and didn't attempt to get some value out of it (whether that be a paywall, adding advertisements, or the least visible option: tracking).

> And again, this scenario applies to most of the sites you likely visit every day, not just Wordle.

This is the most important point, IMO. Digital surveillance (by governments and companies) is absolutely a pressing issue, but things like cell phone geolocation or ISP logs seem like much bigger threats than Wordle. I suppose it makes for a more current and eye-catching headline, though.
Excellent info. Fascinating and interesting.
The jobs of the future never materialized. Receptionists are doing the same thing they always did. People use more computers now, but literally children can use computers. I’d even argue that our service-oriented economy requires even less education and intellectual horsepower than the manufacturing and construction oriented economy of the past.

I strongly suspect our economy would continue to run fine if half the people who go to college now never went (and we banned the practice of requiring college degrees as a threshold filter for people who have their shit minimally together).
I am not an expert, so forgive me for asking, Does Zsh also has this pitfalls?
Lots are, more aren’t, and people seem more wired to care about the awful ones than they should. The lesson from 7th grade is that you need to look for the few decent people out of the roomful of assholes and indifferents. Tune the latter out.

You cannot be famous and on social media without an adequately thick skin. At least on social media they’re not in the actual physical room with you (that you can tell).

I know, easier said than done.
Awesome info.
Yes. But mostly aneutronic fusion is possible, in principle.

"Side reactions" produce neutrons and gamma rays, and fusion products can get involved in side reactions too, also producing neutrons and gamma rays. If you can keep recirculating the desired reactants, filtering out the products and side products, those reactions can be kept to a low level.
Password managers just move the the problem somewhere else IMO. Saving passwords with your browser is even worse.

Passwords should not be rotated unless they have been comphremised. Password rotation is the problem, not your password.

Use different teirs of passwords. Have a single password u use for anything that is non-senstive, and then go custom on anything that is. Only login to those sensitive services from 1 devices, forgo your convience. These custom passwords should be very rarely be used and u can come up with some custom way to store / remmeber them. Atleast then i have to spend hours and hours and hours on your box, looking, instead of minutes.

I find it more interesting the lack of comments than anything else - I'm not sure this software is a good idea, but regardless, nobody uses long form messaging anymore? I.e. if you write anything, you likely already have a solution you are content with, or you use twitter or YouTube comments and largely couldn't care less...
I went to try out this service and the sign up process feels pretty invasive: a phone number, a code, my email, a code, and then "pick a username" - with no indication of what sort of visibility it's going to have or how far and wide on the service it's going to go.

I'd prefer to fill out a reCaptcha.
Instead of pointing out why I think something is wrong I just starting asking questions dancing around the subject. A lot of times it comes down to just getting to "What problem are we trying to solve here?"

Many times the original person might have made some small assumption and then that filters down and causes the current situation to be "wrong". Or maybe I am making the wrong assumption and I simply need to understand what the problem is, at its simplest, that we are all working together to find a solution for.
This is an entirely different thesis. You said that starting diet and exercise together is harder in terms of your body finding balance. Now you’re talking primarily about logistics and mental impact.
> conveys a set of concepts in a succinct manner by way of shared convention

Except that is not the case here. "Buyer Beware" is more succinct and in the same language as the rest of the headline. It's also not a domain-specific term, so shared convention is out. The author is sprinkling on some Latin to seem smarter.

Totally. Or use rails for your web app, and something else for your queue processing. Rails is nice for rails things. Rails is scales for serving web apps much better than DJ/Sidekiq do at serving queues.
I think that it is extremely dangerous to start freezing every single financial provider; banks/credit cards/investment firms/crowdfunding/crypto/insurance, for anyone directly or "indirectly" supporting the protests. That is insanely ripe for abuse, whether you agree with the current situation or not.

If laws are being broken, arrest the perpetrators and charge them with a crime. Follow the judicial process. What is happening here has very little oversight and seems to be an entirely disproportionate response.

You say that institutions have the right to 'not do deals with you', but that's not what's happening. Business is being explicitly instructed not to do business with them, what if they want to offer their services?

It's not simply the 'ability to exercise rights', it is denial of a fundamental aspect of living; being able to transact with your peers. Historically this wouldn't have been such an issue, but as 'non-custodial' money is fast disappearing, it poses risks for all of us.
This is very cool. Imagine using this for checking if a group ID in an ACL is present in a subject's group list. Binary search is fast, but this might be faster.
In two to four years? I'm sorry but that's not realistic. It will be bigger than it is now. But not 1000% bigger. Probably not 100% bigger.
Total body calorie expenditure seems decoupled.

Exercise obviously must burn calories because work is being done. The body can’t overcome physics.

The nuance, and the surprising thing, is that other parts of the body seem to adjust their energy levels to compensate. If you don’t do a lot of exercise, something else burns calories. If you do exercise, the “something else” burns less.

What is the something else? That’s the mystery that still needs to be solved. And by extension, what are the limits of the something else? After all, there are well-documented examples of extreme athletes who consume lots of calories without gaining mass.
> Applications trust /dev/urandom to be secure.

That is decidedly not true. /dev/urandom is not guaranteed to be secure upon boot before enough entropy is gathered by the system, but it is guaranteed to not block indefinitely. The patch changes this contract by making /dev/urandom guaranteed secure and maybe block indefinitely if some unlikely edge case is encountered.
Asteroid mining. I really cant believe its not on Elon's mind, talk about disruptive!
Being against wasting tax money is a principled stance. There is no possibility of current work leading to practical power on a time scale of less than multiple decades, and even then only if a mostly aneutronic form is achieved, which very few are working on.
Is there an offline command line dictionary?
No worries. I took Latin for three years in school and did a double take because I confused it with "cave canem": Beware of the dog!
Personally I prefer to keep most nontrivial validation at the app level. Application code is typically easier to change (redeploying is often easier than a database migration), and it also makes error handling easier.
A few of those people getting access to a submarine or just building a robot to go down there is a lot more likely than them building a vehicle and equipment to land on Mars and assault the habitat there.
The logistics do not just revolve around safety (although that is a major factor), its also stuff like noise and environmental pollution. Residents werent happy with the Concorde noise, people are going to be furious with the noise of a Starship taking off. All of the launches are going to have to be done offshore essentially to avoid this, so now youre also looking at spending probably a couple hours waiting on ferries to come and go, and at that point, who even wants to deal with everything related to that kind of point to point transfer? Thats not even mentioning stuff like being uncomfortable while riding.

All of this plus even if it wasnt too loud, you need countries to let you fly your rocket over their airspace constantly.

We can mention the launches to put millions of tons on Mars, but personally Ill believe that when I see it. That is going to have a massive cost, and I dont see that happening particularly soon at all, even if Starship gets to be completely operational.
Oh, I am very happy to answer this to the extent I can. Whey protein impacts my blood glucose in confusing ways! Most days, I'll have a whey protein shake that consists of one scoop whey protein, a little bit of coffee for taste, and some almond milk. This will typically be my first meal after ~12-16 hours without eating. The correct dose of insulin for this shake can vary from 2 units of insulin to 4.

First, I believe you're correct that gluconeogenesis happens rarely. More specifically, I believe it happens in the absence of carbohydrates in the food you consume. Since I eat a low carb diet, it would make sense that I experience gluconeogenesis.

Second, have I noticed a spike in glucose? Yes! I have to take some amount of insulin if I have a protein shake. The coffee has no effect, so any effect comes from the almond milk and whey. There's maybe half a cup of almond milk in my shakes which is close to negligible. We can probably assume that whey drives most of the glucose effects from my shake.

Third, why is there so much variance in my blood glucose response and insulin requirements? Here, I do not have a defined answer. One aspect may be that whey is quickly digested. The quick digestion may accelerate the effect of gluconeogenesis. Another factor may be the state of the glucose reserves in my liver before I consume the whey. If I'm in a state of ketosis, it may be that my body accelerates gluconeogenesis because it believes it's in a carbohydrate shortage. In this situation, the glucose spike may exceed what would otherwise be expected. There's a few other things such as exercise I'd include here, but I don't have a single definitive answer to this.

A final note: In some sense, I can feel/anticipate my insulin sensitivity during the day. I cannot explain this in writing in any coherent way, but I have decent intuition on what insulin dose between 2 and 4 units I should pick each day. Or, before bed, even if my blood sugar appears constant and in-range, I may anticipate that it'll go up and down as I sleep and eat/inject insulin accordingly. One part of this intuition is "knowing" rather a protein heavy meal will kick into gluconeogenesis while I sleep. Anyways, I can answer more, but as you can perhaps tell, most of my explanations are of the waves hands variety.
You would partner with doctors at a research institution that had lots of patients of this type, and the doctors would need to know how to run a clinical trial. But realistically, you would do this in any number of ways using existing samples before running a trial. Tissue samples are fairly easy to get.
Good article, but here’s a few minor things.

> we combine the vector masks using the packs instruction and readily extract it using movemask just once

Blend instructions are generally slightly faster than pack instructions, _mm256_blend_epi16 in that case. The order is not the same so the permute() function needs different shuffle vector, but otherwise it should work the same way.

> B-tree from Abseil to the comparison, which is the only widely-used B-tree implementation I know of

Another one: https://github.com/tlx/tlx/tree/master/tlx/container It’s not using any SIMD but the code quality is OK, I didn’t have much issues vectorizing the performance-critical pieces in my projects.
The only person I’ve ever seen get fired due to incompetence was a mis-hire. Someone someone with junior level skills had the title of senior and it took them weeks or months to do basic tasks. They also had poor people skills. I honestly just don’t know how they got hired.

If you’ve got the dev skills that’s what matters the most. Leaning internal systems and dev processes is stuff you will pick up with time.

If git is slowing you down - invest your off hours in learning git. Likewise for anything else.
I have a bias towards the idea that we are very different, and it really depends on many unknown factors that apply only to one specific individual.
For me I lose my appetite for about a half hour, I was taught it's simply blood from your stomach being used elsewhere. After a short recovery period I'm definitely extra hungry.
Why is seeing the syntax of a programming language so interesting? I think that syntax is one of the least interesting aspects of a programming language.
When I first got my Tesla, the “gas” pedal was annoyingly further forward than the brake pedal. As “full self driving” progressed I drive “manually” increasingly less often and now what once annoyed me is convenient, I can easily rest my foot there near the gas pedal without accidentally pressing it, at the ready to hit the brake pedal if needed which is located next to where my foot sits. It took several years before the design started to make sense and grew on me.

When your car drives more and more autonomously having manual controls that can accidentally be activated start to make less sense, we’re not there yet, but someday there will likely be no steering wheel at all and people will react the same way they are now.
