Administrating CEPH is unfortunately hard.
Whoa so - I had to kinda dig to get to the Lvalues section of the docs, but ya really bury the lede there! I love the concept of x.!o = 3 and !x.o = {copy of x, with o=whatever}. I didn't read far enough to understand whether this makes deep clones with sub-objects. (I'm guessing...not?) Still, that itself is very innovative.
Brain connectometry changes in space travelers after long-duration spaceflight
Yeah I could never be on a video call for that long. There is a subprocess in my brain that starts running at 95% when I'm on a video call, like a kind of performance anxiety. I can deal with longer voice calls, but I can't really work during a call so it's only useful for syncing up. A call longer than an hour has probably become inefficient in some dimension.
How sapient is your dog? This is calling for more humane treatment when slaughtering these creatures. I'd prefer it didn't happen at all.
testing/quick is not coverage-driven and so not good at truly "interesting" input cases. It's OK for simple invariants (e.g. anything arithmetic with an inverse) but I would not trust it to tell me anything interesting about a parser. At this stage I might even rely on the fuzzer to test simple invariants because the tooling is nicer.
Simplify Salaries with Powerful Payroll
> Developers being unable maintaining both business logic and technical details in head at the same time are usually not hired. Actually this is their stated job description most of the time, translate logic into implementation. If this gives frustration probably better to look for some other occupation.

Feels like a reductionist statement. When working on a large codebase (call it legacy even, as everything devolves into legacy code given enough years), it's impossible to keep all the details in your head. Code review can provide the additional context missing to the developer implementing a task, but I'm sure you've been in the same situation before; where a feature change, even small in scope would crisscross multiple files, and without testing it out you're unable to review conformance.

As an example. When I was team lead on a large and legacy SaaS project in the past, I pretty often would pair with other developers on the team, and their input as well as my input had us catch situations that while developing in isolation we could have missed. Even in a standard code review. Because during development we were deeply entrenched in the code and able to often try out multiple approaches for a problem.
It reduces motion, but it does not remove that transition.

It is infuriating, as someone who is use to the instant switching of i3, I can't believe that it's not possible in MacOS.

My work arounds are to not use the native fullscreen for anything, and just do my best to remove window-titles/decorations from every app i use and then make them "fake full screen"
Just a nit: I fully agree with you that deep inside, Microsoft is still as evil as in the past (competition forced them to hide it a bit better is all). But I'm still all in on the `new’ Microsoft. I don't think these two necessarily exclude each other.

I mean the alternatives are Linux, which I haven't the patience for, or Apple which is also evil but just in different ways.
But that forced approach only worked on the people who had auto-update enabled. For people like me who had WU disabled it didn't affect me at all.
Currently not a Windows user, but I'm interested in developing applications for major desktop operating systems.

I wonder how React Native program performs when compared to the native one. Specifically, how many memory & CPU does a React Native program consume compare to a native one with the same functionality?

The blog didn't provide the information, but it did mentioned that "... performance and accessibility of WebView UX tend not to be as good as a native equivalent". I'm just curious.

Thanks!
We can disagree on those premises, but hopefully agree that corporatism better describes the observed phenomenon.

Maybe someone else here can take up the more contentious elements of your assertion. There's very little I can say here on HN about these points.
What are you talking about? Microsoft's Text-To-Speech APIs are the best on the market. Google's are definitely a distant second: not as many languages, not as many voices, and the output is nowhere near as good. After those two, there isn't really anything left worth mentioning.

This is sort of well-articulated and someone thought about it a lot. The salaries seem fine, as long as there’s 1MM in liquid equity to go with the L7 one like Google does.

But it doesn’t seem to address the real issue (to which I also don’t have a final answer): the jock/nerd thing is still playing out.

If, as I believe is mostly true, A16 is pretty on the money with the software eats the world thing: hackers “should” today and inevitably will be the highest paid people possibly excepting the best salesperson.

If you worked successfully on an optimizing compiler all day, anything that an MBA teaches is borderline boring.

COVID/WFH only turbocharges this: tall white guys have way less edge over Zoom.

It’s going to be a painful, but ultimately necessary transition where everyone whose math stopped at calc has their TC stop at 150-200k, and that money/seniority/prestige goes to the only truly irreplaceable people, again with the notable exception of the sales guy.
> The researchers found that the median security release comes within four days of the corresponding fix. But in some cases, security releases are delayed up to 20 days.

I am not really surprised. The people making the security fixes are likely not the ones who find and report the issue and the devs are then stuck playing catch up. (Assuming there's not "ethical disclosure").

> To improve the security of open source software, the researchers recommend that package maintainers keep security fixes private until their release.

Keeping the fixes private is a good idea but is only effective if the vuln. isn't already make public by a third party (like the guy who found it).

But aside from that small nitpick, I agree with the study's recommendations as described in the article.
Race is a social construct invented by colonizers (whites) as a way to categorize and other-ize everyone else. It has no biological or ethnic or cultural meaning. Race is not an inherent thing, but a complex relationship between groups of people with unequal power and privileges.
I moved from Mac to FreeBSD for my daily driver and I love it. But I use a desktop and don't use neither Bluetooth nor WiFi. Didn't even try to get them going.

FreeBSD does have container tech, in fact it had it before Linux did. It's just not the same tech, its jails are its own invention.

And gaming isn't really a thing on Mac either.

Ps I use all OSes under the sun. Windows for gaming, Mac for work, Linux for servers and FreeBSD for my main desktop. I don't really do laptops but I have a Windows 11 laptop from work too.
Thanks. Hoes does WBM get the page? Does the economist let it's crawlers through?
My dog isn't sapient at all. He's quite sentient, though. Judging by the paper we shouldn't be killing octopuses at all, let alone inhumanely.
I wonder. Perhaps they're overseas, in places like China.
In private? Mostly not. But with some exceptions (basically for marketing or advertising purposes--unless it's allowed by the Ts & Cs of some event which is common) any photo taken in public (basically outside your home) is fair game.

ADDED: For those disagreeing: In general, I'll generally respect your wishes if you don't want your photo taken. But (in the US) if you're in a public place, you have no legal recourse (outside of some specific commercial uses). And that's how things are and will continue to be.
I personally do not enjoy pair programming as a regular practice, but the focus here on performance is misplaced while the pedagogical benefits are swept under the rug. In exchange for some performance, I'd expect gains in team robustness. There are things you learn while participating in solving the problem that you'd never encounter during a design meeting or while doing code review. Subtler design problems and technical dead ends can be caught earlier and save substantial time over the typically async rejection process, leading to more productivity over a longer measure of time.
> A few hours on my bike can be 2,000-3,000 additional calories over base metabolic rate.

Are you sure? 2000 kcal in 3 hours is 770 watts of power output.

Edit: Wikipedia [0] says "During a bicycle race, an elite cyclist can produce close to 400 watts of mechanical power over an hour and in short bursts over double that - 1000 to 1100 watts; modern racing bicycles have greater than 95% mechanical efficiency. An adult of good fitness is more likely to average between 50 and 150 watts for an hour of vigorous exercise."

Crawlers are often permitted to get more web visibility. I think the Web Archive also crawls the web as a browser sometimes, so they can't always distinguish between crawlers.

No, those aren't the same things at all. Your parents weren't listening to rock music while saying "I know this is bad for me and I want to stop, but can't."

Comparisons of social media to alcohol and tobacco are apt, it is something that's both harmful and difficult to quit. Rock music and books are not similar.
Cal Newport's book Digital Minimalism suggests doing a 30 day technology detox. That's 30 days offline. I've done it, and I highly recommended it. Three days would not have been long enough for me to not return to ingrained habits when the time was up, nor long enough to start to cultivate other activities to fill the time with.

I had a role as a mentor/go-to-guy for a complicated codebase and had a similar experience. I really enjoyed helping people out and loved the positive interaction, I would never have called it pair-programming and funnily enough we did have some kind of pair programming initiative at the time.

If I were to give any advice to dev leads/teams/management that wants to introduce pair programming, it's good to put people of differing capabilities and expertise together. That way there's some value being added, and you're spreading around the arcane knowledge of your platform.
The key is “fat to muscle ratio”

It’s a body recomp from an untrained person. Pretty common for new lifters.

You’re right though - if they lift better and eat better, that’ll change.
> 1.) Wearable VR becomes affordable, unobtrusive, and ubiquitous

This is way too early though.

They have first mover advantage but haven’t hit the target yet. So in practice they’re only a barely ahead of all the competitors coming from all sides.

I’d compare them to Microsoft during the Windows CE PDA area. They’re the major player in the field but it was so clunky that we were all waiting for the breakthrough. Perhaps MS could have renamed itself to “DigitalMobile” or something like that and put all its weight behind that wave, but I kinda don’t believe they would have pulled it off either way.

By the same token I think Meta’s vision is right, but I assume they are rushing ahead full steam because they clearly see it as an extremely tough race for them.
Apparently 700kcal burned per hour of cycling is a pretty realistic number.

https://www.welovecycling.com/wide/2020/05/14/how-to-convert...

Also resting kcal burn might be around 1800 per day. So 40% increase in of calories burned by hour of cycling per day every day is achievable.

The question is how can you breathe out additional ~10h of CO2 within an hour?

3 times deeper breathes 3 times faster? Because that carbon has to go somewhere.

GE did the same with 3.0.0.0/8 until they sold it to Amazon. When Amazon started actually using those addresses, it created a situation known internally as the “threepocalypse”.

I have no doubt that the first page of HN made me the professional I am now and the comments helped me to forge strong opinions. It has been a while since I started using the HN search engine to know better about technical topics.

Not sure who to but thank you.
To get past the partisanship all you have to do is change the jackets.

Imagine if Hillary Clinton had won in 2016, rallied the extreme left with dog whistles and charged divisive rhetoric, and then had lost to a fairly moderate Republican in 2020.

Before the election can be certified she gives a speech to a mob of angry protestors telling them to march to the capitol. Embedded among them are actual paramilitary and militia groups with strong extreme-left ideologies.

The protestors go full riot, start fights, bludgeon a police officer to death with the American flag, march into the capitol, and start ransacking the place. Many of them are wearing shirts with hammers and sickles on them, "Lenin was right," "Camp gulag," etc. A number of them are dressed in all black and are seen climbing around with zip ties calling the names of various congress members and senators. They erect a gallows out front and are chanting things like "hang Mitch McConnel!"

Clinton is reported by numerous witnesses to be watching the events on TV while she calls and threatens officials in states where her opponent won by a narrow margin, pushing them to overturn the results. She also has a team of attorneys working on tactics to overturn the election. She refuses to give a speech to call off the riot for hours and hours until the national guard shows up to clear the building. Even after that she refuses to concede the election.

I'd call that a coup attempt. You might call it an insurrection. I think that's quibbling over semantics.

I brought it up to argue for the risk posed by complete loss of privacy. We are creating a system of total surveillance that will be available to whatever much worse regime might take power in the future. If the thought of right-wing populist authoritarians is fine with you, imagine instead that it's an American Hugo Chavez or Fidel Castro. That is not out of the question either if the same people backing right wing populism become disillusioned with it and flip to left wing populism instead. Stranger things have happened. For the record that could be every bit as awful as a right wing authoritarian, especially with the kind of surveillance powers they will be able to seize and mobilize.

People who think there's nothing wrong with this panopticon we're building should convert to Islam and move to Xinjiang province.
I would still argue that orderly actions that follow an established code tend to be boring, and that such codes are generally set up to encourage ethical actions.

Wrong. The advice is to use the same vendor/model but from a different production run (batch).
I was objecting to the word "incredibly".
Anecdotally, this has been my experience as well. I tend to think of my base metabolic rate as the integral over my physical activity over the last N years (it used to be N=5, but even that window is way too small I think now). Point being, you can be inactive for a long time without a meaningful change in body fat/weight, but eventually your body adjusts. Or rather, the first gain in body fat is offset by the loss of muscle weight. Once you're at a slower metabolic rate and less muscle, exercise becomes more difficult and it takes years of consistent activity to raise your metabolic rate again.

I'm not sure how base metabolic rate relates to incidental energy expenditure. My gut feeling is that every body has its own limits on energy expenditure, and max TDEE doesn't need to correlate directly with base metabolic rate. That's why I mentioned the integral above. I tend to think of $TDEE_{max} \simeq MBR_{base} + E_{available}$ but $MBR_{base} \simeq \int_{t=-5}^0 TEE(t)$ -- and in my experience, weight loss correlates more with base metabolic rate than with caloric intake ($E_{available}$).
If something is portable to every *nix system which uses the Filesystem Hierarchie Standard (FHS), it's portable enough for every system I ever encountered or worked with.

This isn't me ranting against systems with new ideas about file system layout, this is just me being pragmatic: When it works on all my work-, private- and production-machines, I see no reason to run an extra binary in front of all my shellscripts.
> is anyone actually using a Linux/FreeBSD machine at their workplace?

Yes, in every tech company I worked at, the majority of developers used Linux machines (with fewer using macOS and even fewer Windows).

I've also been using Linux for personal stuff & gaming for 10+ years now.

I know a company that still has its product in ColdFusion. Just because you are not “hot” anymore means that all your code goes away.

The problem that PHP has are not that it is dead or going away (not going to happen). The problem it has is that there is a lot of old code out there. You are probably going to work on something preexisting rather than something new and cool or worse, work on endless customizations to shops, CMSes and so on.

Ruby is interesting on the list though. I wonder how much of that is stuff like gitlab, redmine and so on and how much of that is in house software?
I’m a massive Star Wars fan and wanted to be able to use the force. There’s one scene in Star Wars where Obi-Wan Kenobi waves his hand and closes a door. It’s so simple and that’s what I think most people would use the force for, simple tasks.

The video explains a lot but here are some highlights:

- A camera + raspberry pi are used for the gesture recognition so it can recognize my hand movements.

- To open the door, I used some metal wire, a pulley, and a motor. There’s a thousand ways to open a door, but how would you have done it? I also considered a linear actuator.

- I had trouble increasing the speed of the motor to open the door so instead, I made the total length of the metal wire shorter. Assuming the wind up speed of the motor is constant, reducing the length of the wire by 80% should make it 5x faster.

Any questions? Let me know.
I passed on seven of the first 30, so 23. Some of them depend on assumptions that don't apply here, or are unreasonably difficult (the Thames watershed is huge; Britain has fractures everywhere, and microquakes daily; I don't live near the ocean).

My "tribe" is a mixture of anglo-saxons, normans and celts. The celts, in particular, have been here since before recorded history. Who knows who preceded them; some celtic legends would suggest they were preceded by giants and "little people". Giants are said to grind human bones to make bread.

Honest question: Why browser's integrated password managers (such as chrome's) are not considered an option for most companies which ask you to use 1password, etc?

Taking out of the equation that maybe google can read your passwords... from the endpoint/laptop point of view itself, is it any less secure than those 3rd party password managers? My understanding is that, for example on OSX, they store them in the OS keychain anyway, right? What's so wrong with that?
But before that happens, any amount of "grow or die trying" can take place: as long as inertia keeps the lights on, team "reinvent ourselves!" enthusiastically digs an ever deeper hole. Occasionally those do strike gold I think, but I can't really think of an example right now.

Some might say Nadella Microsoft, or the iPod company, but I'd say that the former wasn't quite down enough to qualify, and iPod-age Apple wasn't a growth bet at all: everything they did at the time would have been considered a success if it only stabilized on the level reached by the CRT iMacs.
