How is 'brisk' defined?

When training for cycling I use heart rate zones to choose the right level of exertion for a workout. Zone 2 (115-145bpm roughly, in my case) is widely thought to be the lowest intensity range that yields positive training adaptation.

So, I wonder- is a brisk walk maybe equivalent to low zone 2 exercise? Or lower than that even?
Yeah, and Tandy graphics were different from EGA or VGA, just enough that you needed to write different display code for them. And you had to get the user to tell you which ports/IRQ numbers half of their hardware was configured at.

We have way better hardware abstractions in the OS today, which I would agree makes modern development easier overall.
> we need a store of calcium to mediate blood pH

Blood pH is regulated mainly by dissolved carbon dioxide and bicarbonate [1]. There's an order of magnitude less calcium in the blood, usually in the form of calcium phosphate, than either of those, and the amount is extremely tightly regulated within a very narrow concentration range -- far too narrow to have a notable effect on pH.

I'm not a physical chemist but there's probably a computable minimum energy necessary.

A quick search popped up https://pubs.acs.org/doi/10.1021/acs.jchemed.0c01194

For example, desalinating seawater with a typical seawater salt concentration of 35 g L–1 (corresponding osmotic pressure of 29.7 bar) and 50% water recovery (i.e., 50% of the feed stream becomes purified water and 50% becomes brine)
requires at least 1.1 kWh per cubic meter of purified water.
Regardless of the desalination technology, it is impossible to desalinate water using less energy than that determined by eq 12.

which a couple other searches seems to be within order unity of the current energy use
Not just lost sales. I've seen a Walmart lose all ability to do credit card sales and after about 5 minutes maybe 10% of people waiting just started leaving with their groceries in their cart and a middle finger raised to the security telling them to stop.

FYI: Google Workspaces's High-Priority Security Events Take 4 Hours to Trigger
Do not rely on Google Workspace's Security Alerts and Events for anything critical.

If your organisation suffers a targeted phishing attack, you'll notice that alerts within your Security Centre don't trigger or fire very quickly. In fact, it might take several hours - which we found out a few weeks ago trying to monitor and test incident response on a VIP's account.

I've attempted to ask Google on this several times - as well as asking simply, "should I rely on Google's Security Alert Centre for Incident Response", to which they respond each time with:

You think that the governments of the world with much poorer people wouldn't jump on something like this? Improving dental health dramatically improves outcomes all across the board.

If something works, someone, somewhere in the world would start using it. Hell, people are willing to use stuff that is flat out harmful simply because some people on the internet said so.

The big issue with bio things is that the human organism has a lot of variation and a lot of cures sorta work for some people some of the time. Consequently, a high enough bar to get FDA clearance has to be significantly strong.

(Two good recent examples: A woman died from oxalate overload from drinking green smoothies and Vitamin C and anti-oxidants can spur cancer growth. Does that mean that everybody should stop drinking green smoothies and taking Vitamin C? Obviously no. But it shows that humans vary and that things aren't always straightforward.)

No, I did not forget that shade exists. It's still uncomfortable in the summer. Once RH hits 100%, evaporation stops cooling and your options are to go without or to use a different thermodynamic cycle.

We've got plenty of freshwater in these parts, but in other places freshwater availability will be the limiting factor. Famously, swamp cooling works great in the desert if you can spare the water.

Some memories, indeed.

How we had it (rural Norway, late 90s/early 00s)

- Some guys would show up and spend 10% of the time on gaming, and like 90% on coding. They'd mainly be at LAN-parties to collect tools and meet other coders. Sometimes they'd show some cool demos they worked on, or some game they were working on

- Shared folders of music, films, and pictures would get copied an masse. A LOT of the pictures were definitely not for the public eye.

- Some LAN-parties would drag on for weeks, and kind of just become LAN-clubs. People would practically live there...I remember a friend hosted one of the last LAN-parties right around the time World of Warcraft got released, and while it was meant to just last for a weekend, 5-6 guys ended up staying there for a solid month, gaming WoW since the host had high-speed internet. Owner didn't mind, as he was equally hooked on the game.

- The older games would only play Age of Empires, and not much else. The competitive gamers would grind StarCraft, and later on CS.

- Playing all the pre 1.6 CS versions was a fun time. They seemed to change quite a bit between each update, until 1.6 became the standard.

- If we encountered some networking problems, someone always knew a 40-year old networking dude that would gladly show up and fix whatever was needed. Same dudes would always have tons of spare parts lying around.

- Right around the time CS 1.6 became popular, we started seeing the first "pro" gaming e-sports teams. Back then, these teams would just play at LAN parties, and then go compete in larger regional LAN parties. The prizes were laughable compared to the modern ones...one clan I knew won like $5000, which was split on 5-6 members? Those guys decided to drop out of school and pursue CS full-time, which lasted around 6 months or so.

- We would have a national LAN party in Hamar (The Gathering), and traveling there from all the way north was a real bitch. Imagine bringing a full-tower case and 19" CRT onboard the plane. Even though the first flat-screens sucked, it was infinitely easier/more practical than those CRT screens.

And lots of other things.
That's where the cartilage was. You can find that hole in your own skull easily enough. There should be a small bump midway up your nasal ridge. That point is called the rhinion. Everything above it is laying on your skull. The parts of the nose below it cover your nasal cavity.
Shock is the only explanation that makes any sense to me. However, remaining "largely silent" for 60 years about it implies that there's other factors at play.
Pretty.

The top 'gradient' demo links me to an Internal JetBrains site, and is broken.

As such, each classroom teacher amongst the Panel Petitioners is entitled to a religious exemption from the Vaccine Mandate."
And, actually, the speed doesn't matter, because the fuel usage of planing hull makes it uneconomic at any speed, even if such speed is greater than displacement hull speed, even though it's infinitely more effective than a displacement hull at those speeds (since a displacement hull cannot reach those speeds basically by definition).

I guess we disagree on what trees do well. I’m in the Midwest with warm semi humid summers. Trees keep the area around them massively cooler, not by evaporation but by shading.

Maybe it’s a disagreement of terms? I guess they aren’t technically “cooling” the area in an active sense, but they absolutely keep it cooler even when it’s 95 and the dew points over 70

Burning Man:

- Environmental impact of roundtrip transportation to the middle of nowhere

- Environmental impact of structures and vehicles

- Environmental impact of burning large amounts of crap

- Environmental impact of littering

- Environmental impact of event-specific clothes, garments, accessories, etc.

- Encouraging others to engage into the activities above

- ...

Do you honestly believe that a person that voluntarily engages into all this pollution cares in any way about the environment? They're people living in a bubble, completely detached from reality.

It annoys me when I write blog posts like this, it's so hard to link to a specific line of code and have that link stay alive and useful/fresh over time.

It’s just been one year and this has been one of the fastest raises in history. Give it some time to work.
here's an example - i'm currently working through porting the blossom algorithm [http://jorisvr.nl/article/maximum-matching] to elixir. the algorithm is complex and has a lot of subparts, but the public interface to it is extremely simple. i feel like it's not just useful but almost essential to test a lot of the little parts in isolation so i can make sure they are working correctly.

i am currently marking all functions as public for simplicity, but i feel like it's a failing of elixir and/or its test framework that i cannot say "private, but an associated test module should be able to see them", and once the code is done i will be exploring some of the third-party solutions people have come up with to hack around the issue. (the other option, of course, is to have a new module that just contains a couple of public methods, and regard the entire implementation module as a private module with public functions)
They weren’t exactly bullseye hits. He got the bullets in the right vicinity, which is admittedly an impressive feat, but it was pure chance that they managed to strike in a way that caused a lethal blow. If one was going through the effort of conspiring with 1-2 other gunmen, then it should have featured better and more intentional targeting, from spaces anywhere along the motorcade route that wouldn’t be so difficult to enter/exit. Or, if we’re talking about a broader planned conspiracy, use a blunter instrument like an IED or another vehicle, or both. Why opt for a sniper at all? The chances of success seem too little for a professional hit, but about right for an unstable radicalized former soldier looking for revolutionary glory.

Also, the car only started accelerating after the hit was made, and it was fairly axial to the bullet trajectory. I dunno know about you, but I can reload a bolt action rifle without dropping aim in under a second. It’s using the rifle as it was designed to be used.

It wasn’t a good shot. It was a lucky shot. One he clearly didn’t fully prepare to land, otherwise he probably wouldn’t have been arrested shortly after in a nearby movie theater. It was hardly sophisticated, and its success hinged almost entirely on blind luck and circumstance, which is the most difficult scenario to protect against.

Oh, Apple Siri absolutely listens to your conversations and targets you too. I have personal experience of this in India where Siri on my friend's iPhone "overheard" our conversation about apps on app store and started showing very specific ads on my mom's iPad (on which Siri was disabled) app store. (This was around the time when Siri was first launched. And I suspect that they are more brazen about this in countries with lax to no privacy laws - both my friend's and my mom's iDevice was bought and activated in the middle-east).
It's because both are great for specific tasks.

You want air changeover. Low changes/hr leads to high indoor co2 and is just in general bad for you.

"ASHRAE empirical research determined that "acceptability" was a function of outdoor (fresh air) ventilation rate and used carbon dioxide as an accurate measurement of occupant presence and activity. Building odors and contaminants would be suitably controlled by this dilution methodology. ASHRAE codified a level of 1,000 ppm of carbon dioxide and specified the use of widely available sense-and-control equipment to assure compliance. The 1989 issue of ASHRAE 62.1-1989 published the whys and wherefores and overrode the 1981 requirements that were aimed at a ventilation level of 5,000 ppm of carbon dioxide (the OSHA workplace limit), federally set to minimize HVAC system energy consumption. This apparently ended the SBS epidemic."

Yeah, I do think the space where manual memory management is actually desirable is pretty narrow - and so I'm kind of baffled that Rust caught on where the likes of OCaml didn't.

> Yep, every time I've ever worked for a manager who wants regular 1:1 meetings "just to touch base"

Huh? Not even slightly.

I scheduled one-on-ones with my reports generally every week and no later than every other week. No exceptions for me.

My reports could always opt out of them if they chose (maybe they were super busy--maybe nothing needed to be covered), but I could do so only very rarely and I forced myself to reschedule.

It is vitally important to make sure that people reporting to me could get my personal attention even when I was super busy.

While I'm sure some of them "fed me platitudes", they also sometimes jumped up and down about something going wrong that they didn't feel comfortable bringing up in public contexts. That's really important.

Making the trade of pay cut for experience is a very personal question. Only you can answer that. If you are not on the hedonistic treadmill and value experience and knowledge more than extra trinkets, then maybe.

I once took an engineering role where I was part-time business development, aka sales. I learnt that I don't have sufficiently hustle personality to be successful at sales. But I have also gained a respect for those who are good at sales. That experience has certainly steered me away from entrepreneurial fantasies.
No shit. Now we just need to figure out how to make them. Until that happens no vehicles should be produced. There needs to be more regulation on the biggest CO2 producers. This isn’t about the planet it’s about our lives. We’re breathing this stuff too.

I totally do not agree with the "don't prewash in the sink" bullshit. It's based on specious reasoning about how "well" automatic dirt sensors can work. And, it does not necessarily waste water. "it depends" -eg if you wipe the plates with a cloth, there may be less running water.

Dishwasher checks by consumer groups do not test egg protein, or avocado. They need to test with real world, tight locking protein and fats.

And with lentils: the amount of fine gritty fibre which can remain in suspension is just fantastic. And then in the rinse cycle, it sits in the feet of plates and cups.

I also believe that electro-coupling between different metals in cutlery means they age faster if you don't space them properly. If they touch, they can make a circuit.

Actually preparing for system designs is a game these days. I went from dreading them to being really confident with them. My day job had minimal interesting or challenging problems. I am also pretty analytical and quantitative in general (for example I think of system designs as applications of queuing theory) - so questions like "what is the firsts request that will fail and how" actually have theoretical grounding without needing exposure in a day job. Happy to share more. I don't won't to come across as an arrogant prick. I could share how embarrassing I failed at system designs but I could caution against thinking system designs are any magical. Happy to share my path (not easy but IL guarantee it is fun if you like numbers and a pen and paper). Also btw I am talking about preparation for system design interviews. There is still a huge diff between doing well in a 45 min interview and still take years (and tons of mistakes) to build a solid distributed system.
Fantastic non-response. Tell me which part is pious.
I have used this in some commercial software before (maybe Illustrator?); my experience was not positive. When you move a node, some not-so-close curves start wiggling, and you think, "I already set that part correctly, stop moving please". It behaves very poorly around rounded corners. Adding points causes the curves to shift, usually not how you want, and then you try to add more points, which causes more shifts, etc. Arc length-based interpolation might do better in this respect, as opposed to the (# of points)-based interpolation which I expect it used.

The alternative, which obeys similar principles, is the Pencil tool. This simply spams out a ton of points to match what you draw. https://news.ycombinator.com/item?id=37460009 mentions that these points can be capably reduced, which could serve your purpose.
I'll add to the anecdotes here: I lost 90 lbs and got fit over the past five years, and my Fitbit played an important role in that.

Initially, it was helpful for me to be aware of my overall physical activity. Weight loss is mostly diet, but I didn't have a clue about my average steps or my heart rate during exercise.

I got to watch my resting heart rate drop from the 70s down to the 40s as I picked up cycling, hiking, and regular walks.

When I began weightlifting and other more strenuous training, I then understood my heart rate zones and could track my progress.

Gaining a deeper understanding of my body and seeing progress over time was very motivating. Definitely a big positive for me.
