I made ScreenMemory. Usually the performance issues happen when users have high resolution monitors (often multiple) and set it to take screenshots very often (like every 2 seconds). It's fair because that's sort of how Rewind works, but ScreenMemory is generally built with longer intervals in mind, the default is 60s. I use this on my 2016 MBP without performance issues.

I have some improvements in the pipeline for lower capture intervals though.

Its not cheating, some books can only be read, while others are improved with audio.

I prefer reading books, there is something special about holding a book in your hands, insering a book mark or jotting down something illegible in the margins.

I have read a massive amount of books in my time as a psychotherapist for 25 years.

For me, it is far better to read books to fully understand and examine the theories, concepts and methods illustrated by the authors. Marginalia comes to its fore.

However, I do listen to my fair share of audiobook. My main gripe with audiobooks is the readers voice. I cannot stand the squeeky, high pitched, robotic, nasally, sounds like AI, might well be AI, especially american female voices. Being British, just one paragraph and I am immediately put off and turn them off.

I have recently tried to listen to "Into the Into the Deep Wood 01, The Witch by Polina Volkova". I had to stop listening after a few paragraphs. If only the reader had a british voice.

I find switching back and forth between pages to find something you remember reading a few days ago is too difficult with an audiobook. No marginalia with audiobooks.

Do authors select who reads their books. maybe they do not. They should have readers from different countries and different languages.

My favourite audiobook reader is David Thorpe. I have the entire series of Mark Dawson's; John Milton, Beatrix Rose, Isabella Rose, Group 15, plus the novellas and more recently the Charlie cooper series.

I do not experience the same excitement reading those books.

Trump insists the United States is 'rigged, crooked and evil':

>“The Witch Hunt continues, and after 6 years and millions of pages of documents, they’ve got nothing. If I had what Hunter and Joe had, it would be the Electric Chair. Our Country is Rigged, Crooked, and Evil — We must bring it back, and FAST. Next stop, Communism!”

So do you have any shred of evidence he's backtracking on all the racism and misogyny and homophobia and transphobia and cruelty and corruption he overcommitted on?

I have a lot of ideas that answer your question, but there are three main reasons why *improving the quality of education* has the highest priority:

- Improves the society in general - Having a well-educated society able to think critically would make further improvements easier (tackling corruption, inefficient healthcare system and justice system as well as political discourse...) - Having an educated workforce should draw in more investors and foreign companies, making it a critical resource, especially in my country whose industry... could be better

I already have a general idea about the mechanics of a system that would make it easy for teachers to enter (parameterized) exercises, solutions, course material, tips for effective learning and other LPTs in a central database, where students can easily practice and that supports a national league "played" as exams in all schools across the country at the same time. It would need to be recorded to avoid cheating (and the recordings should be securely transferred and stored, ofc). It would include a tier system to motivate those who fall behind, on individual, class and school based levels (to support teamwork) with a reasonable rewards system ("drip" acting like irl "skins", gadgets, etc. for the best).

This would significantly boost motivation through competition and gamification, while enabling a better way of evaluating and rewarding teachers' work, which would be based on both improving the absolute amount of well taught course material and relative rank as well as popularity of entered exercises.

As a recent graduate, I currently don't have spare time nor money to invest in this project, but at some point I'll start working towards it.

TUIs are memory-friendly tools for complex tasks and have a different UX feel (can be more comfortable, clear & informative, accessible) to pure CLI or native/web apps.

I think you're being unfair: try steelmanning. Assume that he is genuinely giving his best and most comprehensive analysis of the situation. It might be a flawed analysis, but at least give credit that it's a genuine effort.

The main flaw of the analysis I can see is that he is seeing patterns that aren't there - being used to analyzing complex international economics, and then being confronted with something as simple as this pump and dump scheme.

Computers and China? Hmm ....

For my next computer, e.g., for a Web server, considering an AMD processor, Gigabyte mother board, Western Digital disks (rotating and/or solid state), main memory, video display, etc.

Just checked, none of that comes from China!!! The businesses are in Taiwan, South Korea, the US. Manufacturing is in Taiwan, Thailand, Malaysia, South Korea. The processor design, the US. The equipment for manufacturing the chips, Holland.

So, for my startup, I'm happy!

For a smart phone -- not much interested.

I have xreal air 2 that gets zero use. I dont recommend them that much, working on a laptop is better and since they constantly making newer versions its worth the wait to not buy anything current and wait for the next one which which will be better. I had the buyers regret, wishing I waited longer for the newer version but unless I buy a steam deck to play games Ill probably never use them.

Czech technical university - 2018 - https://www.radioeng.cz/fulltexts/2018/18_04_1155_1165.pdf

But concepts are translatable to other technologies, for example mobile phone network signals (even without decrypting it) which in most populated areas can have hundreds frequencies by itself.

there are literally literally thousands of radio signals around us which can be used for various unintended / non-cooperative purposes. also not only ground based signals, satellites are transmitting all kinds of signals towards earth, some for communication, some for remote sensing / earth observation.

Or not only is it possible to use non-cooperative signals for timing, but also for passive radar. For example DVB-T - you receive bounces/echoes of signal from airplanes, drones and measure its characteristics.

NATO public document - UAV Detection and Localization Using Passive DVB-T Radar MFN and SFN - https://www.sto.nato.int/publications/STO%20Meeting%20Procee...

Good community is around GNURadio, they have all kinds of enthusiast and profesional usecases, explorations, videos, ...

> And surely in order to leverage comparative advantage, an economy would need to know how good they would be at producing every possible good.

Comparative advantage is an emergent property of trade that occurs naturally, it is the default state of being and can only be undermined by government policy.

You benefit from comparative advantage when you buy bread from the bakery instead of spending 2 hours a day baking your own bread.

Imagine how much poorer you'd be if the government put a large tax on you buying bread to force you to bake it yourself, in the name of self-sufficiency.

That's what's happening with these blanket tariffs, instead of targeting only critical defense manufacturing, Trump also wants t-shirt sweatshops to magically come back to the US despite only 4% unemployment. It's rank foolishness.

We had a Lenovo IdeaPad die after 7 months. (An AMD model, in 2021.)

Their support was extremely painful... or deliberately slow. It took 4 phone calls (30-60 minutes each) over 3 weeks to finally get it escalated properly, to issue a replacement.

They would say, "we're escalating" then a week of silence. Then I call back, and they say, "It never got escalated", let me do that now. Repeat, repeat.

Eventually they shipped a replacement Yoga unit. (Motherboards w/AMD CPUs were on multi-month backlog during Covid)

What's the battery durability like with 5 minute flash charging? EV makers quote durability and charging speed, but gloss over the fact that it's typically "either/or" because fast charging normally reduces the life of a battery (as can charging to 100%). Does the charging speed outweigh impact on battery life in this case?

Current electric cars work well because you can fill them at home, reserving the need to fast charge to 100% for special occasions. If you have a home charger there's no need to stick to the same refueling regime as a petrol car, so there's limited advantage in being able to "treat the car like a petrol car".

5 minute charging is good, but put it in context until we have "perfect" batteries that have no significant limitations.

I find experience to be a bad explanation here, because a course can absolutely teach you all these things that are discussed in the article.

Sewing? The course will explain and show you, after which you gain experience by practice. Making financial decisions? This rests a lot on knowing facts about how financials work, and a course is absolutely one correct way of learning those.

For experience, I'd rather think of things like - how do you cope with the death of a loved one? How do you decide who to be or what to do? How do you manage your emotions, streghts and weaknesses?

You need to develop infrastructure (bike lanes and paths) and a cycling culture (which comes with giving kids training in primary school). To give some examples how things work here:

- Most kids get 'traffic training' and have to do a theoretical and practical exam when they are about 10 or 11.

- Building a cycling culture makes car drivers more aware. If car drivers are also cyclists themselves, they are more aware of cyclists. Also, during driving lessons some techniques are practiced, like e.g. opening a door with your hand that is opposite to the door. By doing so, you automatically turn while opening the door, so you can see if any cyclists are passing. All of this makes cycling on roads (as opposed to pavements safer).

- Give bikes a lane, or even better a separate bike path. Only let cars and bikes share a street in low-speed (30 km/h) non-busy streets. Cars, bikes, and pedestrians differ so much in speed that they usually should not be on the same roads.

- Change your laws such that in accidents involving cars <-> bikes or car <-> pedestrian, the car driver always bares a certain amount of liability even if the cyclist/pedestrian is at fault. To a cyclist/pedestrian a car is like a bullet flying by. Putting more liability on the car driver makes them more careful.

- Design your cities so that cycling/walking is preferred. E.g. the city I live uses filtered permeability. As closer you get to the city center, the harder it becomes to get there by car, whereas you can get everywhere easily by bike or by foot. This fosters a culture where biking/walking is the norm, because you can get in different places faster by bike.

It works very well. I don't know of any pedestrians who were hit by a bike.

Typical predatory thinking of a toxic cyclist.

Please avoid the personal attacks and victim-blaming. I have also lived in a country that was not cycling-safe and usually the only way to avoid getting hit is to ride on the pavement (as most natives did). The problem is not the cyclist, but the miserable infrastructure for anything that is not a car.

IMO your logic is all wrong. Comparative Advantage ist just applied "opportunity cost" of time. Humans and resources are unique, everyone has their theoretically "optimal" use of time in terms of economic output.

The invisible hand of the market will let you know what aspect of your output is most valuable for others.

The benefit of this invisible hand is that the "economy" as a whole does not need to know how good they are at producing everything. People just need to know if what they are producing now is more valuable than the next best alternative. Everything else will be sorted out with market forces.

In university lectures we were given the famous argument about olive oil from Greece and that it would never make sense to do our own olive oil because we both lack the natural resources (unique soil + sunshine) which allow olive trees to grow easily and we'd also have much better yields growing other things on the fields.

So to me, both opportunity cost and comparative advantage are really basic building blocks of economic understanding and I'm a bit dumbfounded that someone wouldn't understand these concepts.

This looks like a “make senior folks feel good” article. I get that there’s demand for that (aging society and what not).

The headline says “too much”, but the article doesn’t quantify cluelessness in adults, instead presenting an anecdote.

Presumably those who take the class… aren’t clueless anymore and others don’t need the class?

Or maybe the problem is that people are naive enough to take the class in the first place because they can’t learn life skills this way?

I didn't know that, sounds like a bug. Maybe something can be done to make it easier to know that this is the case for your build.

It's a feature. E.g. if a binary needs to load data files, it needs to know the full path, or you are back to an FHS filesystem layout (which has a lot of issues that Nix tries to solve).

I'd still think that by refusing to build things with unspecified inputs,

I haven't followed development of traditional Linux distributions, but I am pretty sure that they also build in minimal sandboxes that only contain specified dependencies. See e.g. Mock: https://github.com/rpm-software-management/mock

You say "entities" but that term is actually the name for SGML/XML's mechanism to define arbitrary syntactic content for reference/reuse with entity references a la &ref, whereas in SVG you can park shapes/paths/whatever under refs, giving those an id attribute value, and then <use> those element in the body SVG content, which is also what the page you linked is using (for each individual SVG ie. there's no sharing of rectangles across the many pictures since these are pulled-in individually via <embed> inot their own DOM rather than used as inline SVG).

I wonder why SVG's original designers found it necessary to supply an ad-hoc re-implementation of the entity mechanism. I think it might have to do with how rendering properties can be overridden at the usage site? At least I don't think it was established that browsers ignore entity definitions or basically anything in the document prolog/DOCTYPE considering SVG was part of W3C's push to replace HTML's SGMLish legacy syntax with XHTML/XML.

I like your ideas and suspect we're far more on the same page than not.

Nonetheless I compare what we call "capitalism" to chameleon music artists like David Bowie (no disrespect intended to that wonderful artist), who change radically with time, constantly shapeshifting and reinventing. Our grandfather's "capitalism" is unrecognisable from its namesake today.

People often level the accusation against communism that "it has never actually been tried in practice", and I think the same is also true of capitalism. Maybe in the years before just before 1929.

Anyway, what I see today is not a recognisable ideology. It's just a bunch of criminals getting away with it and an effectively lawless USA.

It is a different design decision. You do not have to choose all capabilities of modern browsers when you do sth.

Of course nobody would expect this to take off largely. But aesthetically speaking, I see nothing wrong in the design per se. It is clean, consistent, light and minimalist-like. Terminals just provide a minimalist style that is tested and also familiar to some. It is very easy to get around the website. Pages load fast.

The main drawback I see is lack of multimedia support, obviously (even if supported they would be a bit out of style). But that's not a problem if you do not care about that. And that it is hard to place ads.

Sure, "Web model is objectively better" but also depends what one considers as "web model" because a lot of modern web is just a bloated mess, which I find more annoying thaν a project like this.

Oooh, you sound pissed. Or maybe I'm reading it like that in my head. I don't know why you feel like I was staring at your ego the wrong way — never was my intention to hurt your feelings.

I can tell you though why my comment sounds defensive; it's because I care about the tool and the community invested into it. Despite having virtually no better alternative in its category, it is still not a very popular tool (for various reasons), and the user base is relatively small, the number of active contributors is even smaller.

Disingenuous remarks similar to yours do a disservice to the community of its users, maintainers and interested newcomers.

For what it's worth, the command I described, the one that gave you the impression that you have to type "an incantation" - `C-x 8 RET` bound to (insert-char), you invoke it, and start typing "dash", or "em d" and it finds you the thing. It's also great for inserting emojis and arrows of all sorts, stuff like that. I often debug code inserting log statements with butterflies or dog symbols - easy to quickly spot them. You can type a number and then call it, it will insert that many of the selected character.

Anyway, whatever your goal was with that thought - you imagined it all wrong. Feel free to blame me for not describing it properly, don't blame the tool.

In the EU an average car is 1400 kg (3000 lbs), with most vehicles probably in the 1000-1200 kg range. We don't really want the average here, but the median - and we don't want to compare to the average EV, but to the equivalent EV - comparing an F150 to, say, a model 3 isn't right.

A BYD Dolphin, roughly sized like a VW Polo, is some 400kg heavier than the polo. A Polestar 2 is roughly 500 kg heavier than equivalent sized cars. In other words, something like 33% heavier.
