Really depends on the job. But generally, yes the same applies to Sidekiq. I think there is a queue for Ruby called Sneakers that uses Fibers?

If you're making API calls out to external systems, you can use all of the concurrency that you want because the outside systems are doing all of the work.

If you're making queries to your database, depending on the efficiency of the query you could stress your database without any real benefit to improve the overall response time.

If you're doing memory intensive work on the same system then it can create a potential issue for the server and garbage collection.

If you're doing CPU intensive work, you risk starving other concurrent processes from using the CPU (infinite loops, etc).

Something like the BEAM is setup for this. Each process has it's own HEAP that's immediately reclaimed when the process ends without a global garbage collector. The BEAM scheduler actively intervenes switch which process is executing after a certain amount of CPU time, meaning that an infinite loop or other intensive process wouldn't negatively impact anything else...only itself. It's one of the reasons it typically doesn't perform as well in a straight line benchmark too.

Even on the BEAM you still have to be cautious of stressing the DB, but really you have to worry about that no matter what type of system you're on.
Agreed. Western society is very much in a pattern of decline right now. Whether it's terminal remains to be seen, but the decay is blindingly obvious imo.
There's a widespread social movement in the US which posits that your race and gender identity are very important and you ought to frame everything you do in terms of them, and this movement seems to be influencing the author.

The reason people are using euphemisms is that naming the movement is intensely controversial. The most common term used by its opponents is "woke", but proponents near-universally consider this to be rude; there's no consensus alternative, because many proponents think it's just true and thus giving it a name at all is argumentative. (What do you call the movement of people who think the sky is blue?)
i mean your comments are helpful and useful context but no need to go censoring information just knowing about the existence of things?

I'm not just including precision, but ability to get through defenses - i.e. total battlefield effectiveness.

Precision in terms of "circular error probability" isn't the biggest issue now. Its the EW environment.

My point was if system A gets through defenses 30% of the time, but is 10x cheaper than system B which gets through 80% of the time. System A is generally the better choice, except for some very specific circumstances, very high value targets with limited strike opportunity.

- 2009 was for both charge-coupled device, which is a component for digital imaging (including regular consumer digital cameras), and fibre-optic cables
The Atlantic is the mouthpiece of the imperial Borg, and the editor-in-chief got his position there by writing dishonest drivel in 2002 about Saddam's WMDs and Saddam's links to Al Qaeda in order to whip up popular support for the invasion of Iraq. Here's the damning evidence (note in particular the failure to discuss Saddam's deployment of chemical weapons against Iranian troops with the active support of Reagan and Thatcher):

https://www.newyorker.com/magazine/2002/03/25/the-great-terr...

As far as the Atlantic's take on the limits of acceptable literature at the high school level, it's not hard to understand if one can accept that their ideological grandfather was Carl von Clausewitz (1780-1831). His idea that 'war is a continuation of politics by other means' leads to the conclustion that, in an authoritarian state, education would be a continuation of the state’s political ideology. and the fundamental rationale of education would be to serve the state’s objectives. Thus, the Atlantic supports teaching a version of history, politics, and culture that aims to create loyalty to the state and its leadership as the primary goal of high school level education. From this viewpoint, 'Lies My Teacher Told Me' by James Loewen is heretical blasphemy.

The alternative to rigid indoctination of students is to present them with multiple works with differing viewpoints and have them debate them on the merits - e.g. have them read Conrad's 'Heart of Darkness' as well as Chinua Achebe's 'Things Fall Apart' and let them come to their own conclusions. Also, stop excluding fantasy and science fiction literature from the academic curriculum! The Three-Body Problem is highly suitable for a high school literature course, for example.

The challenge in today's environment is convincing people in elite institutions that liberal authoritarian ideology and censorship - e.g. banning Conrad because they see him as an old white racist - is as much of a threat to a free and open society as conservative authoritarian ideology is.

"Ubi to the affected" is a contradiction of terms
The quote is about literature being "confined" to it. Meaning the overall impression from the reading list you get is that literature is something of the past and concerns only certain race and gender.

The comment refers to what Horowitch’s article counts as literature, not what your teacher/school system counted as a literature.
Damn - best read I've had a while. Tons of golden nuggets with explanations from the people who learned the hard way:

- Deeply understand your users

- Experiment with different strategies
- Create content, especially visual and opinionated
- Leverage your personal strengths
- Collaborate with influential experts
This does a better job of showing an uneasy feeling I have about Kotlin than anything I could say.

- The infix is weird and footgun-y.

- Extension methods on int/double serving as constructors smells funny.

- Using infix operators as constructors but not using infix operators for addition/subtraction smells funny.

In general, at least in a corporate environment switching off Java for Android, I found Kotlin a distracting step sideways.

Code reviews tended to involve a lot of bikeshedding over how to make it Kotlin-y, and there's a sort of "why not?" approach to language features that creates much room for the bikeshedding.

It left me feeling like we were unconciously choosing to have the same arguments C++ programmers had in 1990, all over again. Except it was even more destructive, because those arguments were centered, and conflated with "proper" coding in the fancy new language.

I'm not against new and shiny: I was the first to use Kotlin in the org., and I dove right into Swift. There's something alarming with this transition.

I'm heartened by starting to see some debate in Android dev communities about whether Kotlin/Compose were a bridge to nowhere that shouldn't have been a focus for years.

> I mean I don't think the perks I get total that.

It's disappointing to see this undervaluation of OSS. The pledge to pay $2k/dev/yr is about meaningfully giving back to the OSS community that supplies us with invaluable tools -- tools which we build businesses on top of -- for free. It's about giving back for the many "perks" we partake in, even though many undervalue them or even feel entitled to
them.

You're right that not every company can afford $2k/dev/yr, and that's okay. But I think this pledge is for the ones that can.

There are other initiatives like https://fossfunders.com that don't have such a high bar.
System prompts sometimes contain the information that "it" is an LLM.

Reactive programming was my object lesson here. Years ago I had a very brief love affair with .NET's Reactive Extensions Framework for a streaming data intake pipeline for a BI system. It made writing the data transformation code so quick and easy!

That all evaporated within a month of initial release, when I had to diagnose my first production defect. It turns out that usable call stacks are a very nice thing to have in your exception reports! I could already see that, in the long run, this design was going to cost us more to maintain than it saved us in initial development costs. Soon after, the team and I agreed to revert to doing it the crufty old boring way, and we were ultimately glad we did.

I've subsequently had similar experiences with other "easy button" compute frameworks, IoC containers, etc. They were all high quality pieces of software that did a good job of doing what they do, and possibly did save on initial development costs. But when the beeper wakes you up at 3AM, nothing beats a readable call stack that corresponds very closely to the lexical structure of the code.

The moral of the story for me has been that it's always good to experiment with clever tools techniques. But you should also remember that you have the option to thank them for the learning experience they provided while choosing to put something unsexy into production.

In Nobel win, AI researchers Hopfield and Hinton take 2024 Physics Prize
Long before the CAP theorem paper I remember learning the same thing in the context of routing protocols like BGP and it being an "aha moment". It really helped me understand that there is no single version of the state of distributed systems and that it is all local and a matter of perspective under a partition. When the paper came out I remember thinking how trivial and obvious the conclusion was, and it confused me that it was getting attention ... but in retrospect the reformulation and acronym helped bring understanding to a far broader audience, especially software people. That's really good impact and effectiveness and I wish more academic papers were focused on this.
usually when an OP is asking about 1-1 accounts, it's more of a free vs paid thing and they care less if the account is using automation (bots) than abusing free offerings. This is certainly viewed as more important with the AI hype cycle, and it costing more to run while also almost requiring a free tier

In my experience, it's not worth worrying about until you have users, and if you have this problem, it's a good sign and you'll have the resources to better deal with it by then

No, this is just plain and simple racism and sexism on the author's part.
Yes, this is the sensible and necessary side of microservices...

Now, take your auth logic and put it on a 3rd party, rewriting all of your auth to do so.

Now, make your database shared across multiple distribution platforms and 12 services (aws, cloud, heroku, tableau).

When one of your 15 services goes offline for temporary maintenance, for some reason your entire website goes down.

The 17th service you created has an ip address switch and is missing and the response to all urls is the default apache gateway page.

The 24th service upgraded from Node 12 and is now broken, while the 26th service built in Go doesn't compile on the specific linux variant of one of your devs.

Before you know it, you're just doing maintenance work because something is broken and it isn't your code, it's some random downtime or brittleness that is inherent in microservice architecture.

I did an ocean crossing a few months back and I succumbed to the siren call of Starlink. Really should have just caught up on my Kindle.
Yeah it’s all fine, it only displaced a few thousand people from their homes and made an area an uninhabitable wasteland. It’s only going to cost ~$500 billion in total for cleanup[0]. Nevermind the capital loss from the destruction of the power plant itself. Nuclear is definitely a great idea.

[0]: https://en.m.wikipedia.org/wiki/Fukushima_nuclear_accident_c...

Sarcasm aside, it's extremely frustrating when deaths are the only dimension people use to compare with other electricity sources. You can't just put on a blindfold and ignore all of the other factors. Just because only a handful of deaths can be directly attributed, doesn't mean nuclear isn't an absolute nightmare when it goes wrong.
Well the food addiction or sedentariness addiction diagnosis are a lot more controversial than a heroin addiction diagnosis, though I can see how they have some things in common. I think labelling any observable manifestation of poor impulse control as a medical addiction is more of a social trend than a legitimate scientific discovery.

The bigger difference though is that we all eat food, and for most of us includes at least some absolutely delicious food that would be incredibly unhealthy to eat in large quantities. We’re all (more or less) exposed to the “addictive substance”, it’s just some people have the ability to deprive ourselves constantly indulging that impulse, while others don’t. We don’t however, need to take small doses of heroin every day to survive.
Great show I loved as a kid! I have the series collection on DVD.
You're both wrong. Obesity increasingly looks like addiction--as with any addiction, it takes two to tango. But once you have an addict, shame is an ineffective treatment. Debating giving an obese person GLP-1 drugs is akin to challenging methadone for heroin addicts.
Mozilla wants to start a conversation about who controls AI
I find the prize a bit odd this time since it focused on Hopfield networks and Boltzmann machines. Picking those two architectures in particular seems a bit arbitrary. Besides, Parisi got the prize last year (edit: actually 2021, time flies) for spin glasses. Hopfield networks are quite related. They could have included Hopfield & Hinton too, and it would have looked more coherent.

It is also concerning that lately the Nobel Committee seems to be ignoring fundamental broad theoretical contributions. In this case, backpropagation, where Seppo Linnainmaa could have been one of the awardees. It is a bit sad he and others who have already passed away get little credit for something so fundamental.
Fine, you want precision? 22% of books curated out of public schools included sexual content such as statutory rape, drawn CSAM, and various other topics not appropriate for public education.
I'm pretty sure they'd also get thrown out of those meetings for "merely reading out loud (to adults!)" the content of certain sections of the Bible.

Also that sounds more like an argument for age restrictions. The kind of content most people would find acceptable for their 6-year-old to read is quite different from that of a 16-year-old.

Gazing into a mirror is not generally a recipe for the growth we want in students.

Kids are strongly influenced by the people around them, especially authority figures. I wonder how much her own views about long books written by old white men shape the views of her students.
I'm curious about how that stuff works. What prevents someone from faking one of those scanner devices and generating fake hashes of nonexistent eyes? Or producing fake eyes for scanning?

The airport pay-to-skip-lines company (can't remember their name) uses a similar iris scanner setup to check people in, but presumably there they have tight controls over their devices and have human employees always standing by to try to limit abuse. It'd be pretty suspicious if you walked in with a fake eyeball or such there.

But anyone can buy a Worldcoin orb, right? Is it going to be like the console DRM wars, where once someone manages to root or extract a private key from such from a device, they can use it to make fake identities?
I wonder if this pushes them closer to being willing to sell off their US operations (I'm skeptical they ever will but who knows)
Engineering Managers' Guide to Effective Annual Feedback
Kotlin has the problem of "I had N problems, so I think I can create 1 new solution, now I have N+1 problems" (obligatory https://xkcd.com/927/).

The 'money/percent/usd' are almost like new keywords - which to me seems bad. Why not a formatter or another tool that simplifies but doesn't make it too clever or worse, hard to read.

Kotlin is really cool and arguably better than Java. But the language is very hard to read ('easy' to write). And with so many different ways of doing a single thing (and many of them exist to support Java, I understand) plus new 'macro-like' things expanding the language automagically makes it very hard to grasp.

I hope I am not the only one with this same feeling...

anyone thinking about hanging their hat on writing decentralized, local first, crdt-driven software should also consider the complexity of changing your schema when there are potentially thousands of clients with different opinions of what that schema should be. some interesting research has been done[1] in this domain but i haven't seen any library of this ilk that supports real-world schema evolution in a way doesn't make me really, really wish i had a proper backend to lay down the law. the fact that migrations are in a "coming soon" state makes me wary of using jazz, and i wonder how they would approach this problem with the library as it is now.

On the contrary. If one cannot appreciate a work of art unless it reflects them on the surface, that is a character flaw. We must discourage such things, not give into it as the current establishment does.
WFH Favorites from Amazon (Lifestyle/Books/Home Office Upgrades)
I don't think the 'they' you refer to exist anymore. It isn't that tech workers got corrupted by power. There was a brief (20 year?) period where workers had more leverage than owners. Asset owners were forced to bend to workers, pay huge salaries and beg to invest in companies they didn't understand.

Now asset owners have the whole thing comfortably under their thumb, every large tech co has MBAs throughout and schools have been pumping out engineers for 20 years so workers have no leverage. It has become the same as every other large industry.
