harry8··on U.S. math scores drop on major international test
> I do feel a lot of ordinary kids would miss out ...

Or maybe simply miss out on being properly educated so that science and engineering isn't magic passed down by the authority of the ordained clever people wearing the robes but instead something that can be understood.

It's actually quite difficult (impossible?) to have an informed opinion on any government policy if you don't understand some stats and probability. Yet the newspapers are dominated by people writing who completely lack this understanding.

harry8··on Egoless Engineering
This works both ways or it doesn't at all.

You want selfless devotion to the goal then you damn well better not be wasting my time and cutting costs at the expense of my productivity.

Managers who don't know what they're talking about and insist they do and insist they are right causing massive lost time, then want to hold meeting after meeting about how it is everyone else's fault. You've seen it. Why am I working long hours doing work, some of which is shovelling sand that need shovelling because I'm not too good for it when if that idiot had been restrained to their level of competence we'd already have delivered and I'd see more of my family. Selfless devotion? To what?

In the old days when SSDs were 'expensive' and companies economised and didn't immediately buy them for the team because my time isn't worth saving but they want me to stay back to get more done for a deadline? Selfless devotion to a goal you're showing clearly you don't care about.

This stuff is really normal. You have stories, everyone does. And so we take the path that is best for ourselves and those we like. Any other choice isn't "egoless" it's insane.

Managing a team is hard. Keeping idiots from having idiotic influence is hard. Spotting who is managing up is hard. Noticing, supporting and retaining who is good is hard.

Having someone with a massive ego who you might cross the road to avoid having to socially interact with other than they do a decent job of that hard managing might work out better than "Egoless."

Good reminder for me and anyone else right there, nicely put.

harry8··on Dell is posting unsigned updates to their website which fail to install
Yep.

Best to do that without telling your customers that long established behaviour would kill it. Dell.

harry8··on Dell is posting unsigned updates to their website which fail to install
Sure wouldn’t ever again!

At the time i was probably a little preoccupied and just clicked yes, safe in the delusion that no distro nor any hardware vendor would ever push a laptop bricking bios update.

Sibling got it. Feel disabled sleep so if you didn’t shut it down and wait before closing the lid and putting in your bag it fried the mobo. Yeah. If you treated your laptop like a laptop the way you’d used it hundreds of times that was now like tossing it in the dishwasher.

Unbelievable. Yet it happened. I hate Dell. I’m not letting go of that anger. Ubuntu, meh. Pretty poor but still not Dell.

harry8··on Dell is posting unsigned updates to their website which fail to install
Crucifixion? Really? Come on now...

I paid Dell a bunch of money for a laptop. They pushed a bios update, that ubuntu kindly relayed to me that meant when I closed the lid and put the laptop in my bag as I sat beside my daughter's ICU bed, it fried the motherboard. No really. That was the /purpose/ of the bios "upgrade." Warranty after they remotely fried my machine? No, because it worked as designed.

So yeah going bayesian given none of us can be 100% sure about anything, my prior on Dell is they suck donkeys' gonads on all levels. Competence, honesty, service, everything - until evidence shows otherwise and I've just told you why.

Why is your prior that Dell are competent even when evidence suggests otherwise?

harry8··on Why one would use Qubes OS? (2023)
There used to be cryopid in the days of 32 bit x86 and it was great and Bernard is cool.

Somehow I doubt it's still a thing but haven't had a reason to check.

harry8··on Fair coins tend to land on the side they started
Pr(same side)=0.508, 95% credible interval (CI) [0.506,0.509]

Toss it 100 times, overstating the effect you'd expect it to land on the same side it started 51 times, opposite side 49.

This seems to have been lost in much of the discussion. Employing this in professional NBA basketball you /might/ get one extra toss win per season out of your 100 games compared to any other way of selecting without taking into account the starting side.

Good luck using this!

Democracy requires the consent of the governed, which I say is absent here.

Dictatorship can and has come out of democracy, this does not make dictatorship democratic.

I don't make predictions about what different companies will do 10 years hence given they will be a collection of people, most of whom don't work there currently, doing business with regulations that don't presently exist.

"May" is just correct usage. How are you sure here? How could you convince a skeptic that it is possible to be sure?

> Apple has a compelling value proposition.

No. Apple has a proposition that /may/ be better than the current alternatives?

Easier than you might think to set up. Set and forget. Do it for your family and friends maybe. Sell routers pre-configured maybe.

Not /the/ answer. Just one not-nothing step.

are they really able to claim to be democratic if they are analyzing and storing forever all this data without the informed and explicit consent of the surveilled?

I suggest that the number of people who are aware of the full extent of the scale of this surveillance AND have fully thought through all of the future implications of this comapred to the populations is a rounding error. A minority are capable of mouthing something cynical like "oh yeah they record everything." With no further thinking beyond that. Perhaps even here in this community.

Heh, but it can't be that, no reason to think llms can count brackets needing a close any more than they can count words.

so now the race is to get the order in (or out) @ 29.999999985 seconds or 15nS before the batch deadline. Interesting twist on the game. Unlikely to change who wins it, could it be worse for retail punters?

We need to kill "front running" as a criticism of low-latency algo trding with fire. It's garbage.

Front running is highly illegal and is where a broker knows a client is going to do a big trade due to inside information and trades on the account of others (themselves, typically) to exploit that inside information. It's a straight up cheat.

Inferring from market data alone which way a price will move is legal, honest, been attempted since forever and absolutely fine. Also very, very difficult. Anyone who can do it makes the market more efficient, reduces the money available by doing it (which goes into investors pockets through tighter spreads) and really earns their money. You don't have to like them if you don't want to but it's worlds apart from front running using inside information.

Where did algo trading profit come from? Won by being more competitive from brokers profit with a good chunk of that broker profit going to investors. Spreads are tighter.

Where are the clients' yachts? Well tech did something about the some of the broker ripoffs earning their yachts - which puts money in your pocket.

I also endorse FitoTrack on droid as a user.

Along with Out-Run on iphone.

Both work well and are pleasant to use. Record your exercise for yourself with no cloud.

harry8··on Ask HN: Can calculus be taught without differentiating or integrating by hand?
Dunno if I agree with this, just sounding it out seeing how it feels.

>>Can literacy be taught with hitting students with a stick when they err?

>And then the answer is yes, as this is how it is done. (19th century).

>Now, why would be want to do otherwise? Why would we ever want people to learn less?

Maybe you don't learn less by not being hit? Even if my grandparents all had vastly better handwriting than myself. Perhaps I learned some other things not being met with such hostility in my education? I don't know for sure.

At some level of complexity we learn "too hard for me to integrate by hand" and also stop learning how to perform more and more complex integrals. We stop. Where is the most productive place, to maximise useful learning, to stop?

Maybe not being hit with a stick cost me beautiful copperplate handwriting. I feel it was more productive for me to not be hit. I can see someone taking a different view on that with regards themselves. "Never did me any harm" is still a pervasive way of thinking about what others call child abuse. Not many wish they were hit more.

What do you get out of integrating by hand? At each step ratcheting up complexity from y=x, through each increasingly complex function type to where you stopped? Are there diminishing returns? Or do you get past a threshold opening up whole new areas of understanding otherwise not experienced? Something else?

I note anyone can integrate y=x and get 1/2x^2 + c so I don't think avoiding this integration by hand is the point.

I still use it, it seems a little stagnant in development nowadays. No ssl on the website etc.

The free software distros really lost something going all in on open/libre office which is just not nearly as good as a replacement for excel. I think if it was still the free software goto, installed by default first choice etc there would be more development. The feature list and quality is impressive and has been for many years.

Thought there might be more worth exploring from this community. ;-)

harry8··on C++ proposal: There are exactly 8 bits in a byte
Hahaha, you're including Bjarne in that sweeping generalization? C++ has long had a culture problem revolving around arrogance an belittling others, maybe it is growing out of it?

I would point out that for any language, if one has to follow the standards committee closely to be an effective programmer in that language, complexity is likely to be an issue. Fortunately in this case it probably isn't required.

I see garbage collection came in c++11 and has now gone. Would following that debacle make many or most c++ programmers more effective?

harry8··on The long road to lazy preemption in the Linux CPU scheduler
Make a syscall for io. Now the kernel takes over and runs whatever it likes for as long as it likes.

Do no syscalls. Timer tick. Kernel takes over and does whatever as well.

No_HZ_FULL, isolated cpu cores, interrupts on some other core and you can spin using 100% cpu forever on a core. Do games do anything like this?

harry8··on C++ proposal: There are exactly 8 bits in a byte
Is C++ capable of deprecating or simplifying anything?

Honest question, haven't followed closely. rand() is broken,I;m told unfixable and last I heard still wasn't deprecated.

Is this proposal a test? "Can we even drop support for a solution to a problem literally nobody has?"

harry8··on Winamp deletes entire GitHub source code repo after a rocky few weeks
the point here is to solve the problem of linking to an LGPL licensed library, to comply you can:

a) release the code of the original LPGL licensed library

b) release it with a patch of any modifications, ie the small change here

c) nothing else. zero. No license changes. No other code of the app affected. No app code needs to be released.

And you are compliant with the LGPL license and can get on with life. So this is not a big deal the way GPL code in the app would be which would require the app code to be re-licensed and released to comply, which is a huge deal and difficult to accomplish.

harry8··on The web I want vs. the one we have
It didn't. It was the best place to find the best news stories, blog posts, journal papers and all the rest on any subject that interested.

Someone who you think is smart,informed and honest says "Mary, who I know, is smart and works in this field wrote about this issue here: link" Could take you to fantastic info you don't see otherwise. Obviously critical thinking and possibly verification required.

Now you don't need that because links are all de-amplified and many of the most thoughtful and interesting have left. This is the real shame of it all.

harry8··on Busy Status Bar
Surely it would be closer to justice if one were to dispatch the various management gurus and architects who claimed open plan was acceptable and any CEO who agreed with that garbage?

Here's a new idea, will it be adopted? Well does it increase office misery - then yes. If one idea gets past that goes the other direction its removal will be the most pressing management concern. Presently the biggest trend in the c-suite is how to end remote work in the face of all its positive metrics. Hot-desking, which has nothing positive about it for anyone, get behind it!

harry8··on Please Don't Make Me Download Another App
You're not seriously suggesting the multiple apple subscription services were brought in because 3rd party apps became a thing?

The original iphone had zero market share on release. First one is free. Just like Appletv, applemusic, icloud storage, apple games subs....

If you think apple's approach has ever been anything else but abusing market power to maximise revenue I've got a bridge for you with microsoft written on the side. (MS are all like "We'd have been crucified for that, well not anymore!" And the race to the bottom of your wallet continues apace.)

harry8··on Please Don't Make Me Download Another App
Counter view: Steve Jobs instincts were about owning everything. Any app should (must) be bought from apple, as a subscription, while holding your data hostage, at their price.
