Absolutely right, although I cannot lift the amounts you list. For me, weight lifting has nothing to do with "power lifting"..

I have a weight-machine and a few barbells in my house, and use them 2-3 times a week, sometimes more, sometimes less. I am older, I have no six-pack, I am not particularly muscular. It's not about that. It's about keeping what you have, and keeping what you have reasonably fit.

Muscles support your joints. Weight training also strengthens the ligaments and tendons that hold everything together. If you do it as "circuit training" (only a few seconds between different exercises), it also serves as cardiovascular exercise. All of this is important for everyone, especially as you get older...

Yes, there are two problems:

1. You are misrepresenting the purpose of your visit and you can get deported and/or barred from entering the country. For example, you can be stopped and asked for your passport at any time (this has happened to me multiple times, even though technically it's against Schengen rules).

2. Visiting for 2-3 days makes sense for a conference, but it makes no sense for a vacation and you will raise flags. This would lead to a request for more information from the consulate plus a delay then a rejection, or just a straight rejection.

The dumbest thing is that all this friction is completely unnecessary. The EU can copy the homework of other countries mentioned by the author of the post, but are unable to for unfathomable bureaucratic reasons.

Speaking of fantasy and books (I assume most people on HN have read the greats like Tolkien), how will the next generation see these worlds? One can hardly find a teenager these days willing to read a single page in a book without browsing on their iPhone. We're yet to see the consequences, I am afraid.

Assuming the country in question requires an explicit business visa for you as an $X citizen to attend a conference, it's probably not a good idea to lie--even though you also probably won't get caught. (Many countries don't draw a distinction between tourism and a routine business trip or some combination thereof for at least some passports however.)

(And as the sibling comment notes, if you're just dropping in for a quick conference and heading home again, that probably is suspicious as a tourist.)
True, but the difference in practical combat ability between people who have been practicing for 10 days, 10 month and 10 years in tiny compared to swords or magic.

Ask HN: Platforms to find online internships to explore my interests
Hey HN!

I'm a 21-year-old traditionally from a non-STEM field who's passionate about STEM. I have been on HN for a while and find this community incredibly resourceful. I'm reaching out to you to find some guidance on where to discover short-term internships or other opportunities online that let me explore my interests.

I'm particularly interested in exploring various STEM disciplines, be it engineering, scientific research or technology. I have been mulling on this idea for a while and I believe that a short-term internship would be a great way to immerse myself in this world while also gaining valuable insights that can shape my future path and career choices.

If you've come across any platforms, companies, research institutions, or even unconventional opportunities that offer short-term internships, I'd greatly appreciate it if you could share your insights. Whether it's a research program, an internship opportunity at a start-up or a unique experience you've personally had, your input could be incredibly valuable to me.
Star Wars has guns. They shoot lasers/plasma instead of lead propeller by gun powder, though.

There's fantasies that incorporate various "{propellant}-powered projectile weapons" but your right that they're not common, though (and maybe not considered "classic" fantasy).

There's also alchemical way to work in guns into a fantasy setting not reliant on gun powder. Or why not have gun powder; alchemy+magic could be a superset of science even.
> "Truly an inspired design if that is the case" - it's not the case.

I only read the article and some commenters here saying the windows break. The commenter above provides a reason for it that you say is not true. I stand by my comment, that if it is the case the design is "inspired"

>"Rear doors either do not have an emergency release" - you mean like every coupé ever built? Since when were you protesting coupés? Rear doors not only do not have to have manual releases, but don't even have to exist.

Don't most (all ?) of these cars have rear doors? What do coupés have to do with this? Convertibles don't have a roof but I would expect it in a sedan. If the doors exist there sould be a release that works in the case of this electrcal malfunction.

>"lack and/or ambiguity of signifiers" - the front manual release handle is not only not ambiguous, but is far more prominent than the electric release button, so most people with no experience with the car pull it instead of the button.

I expect this is the case for one model? The article has 2 cases of people that own these cars (a model y I think) and could not find the manual release without reading the manual or calling someone. Moreover the confusion you are describing (using the emergency rather than the regular release button) is exactly what ambiguous signifiers result in. This is a design failure as well.

I agree that unlatching the doors in a crash is a part of the crash sequence in many modern cars but these cases are not about crashes.
Sudden power loss or an electrical malfunction should trigger the unlatching of doors and they seem to not. Jaws of life would not be a prudent way to get out of your car in these occasions.

> What is added to our Universe, which causes the inflation?

It's a free parameter in the equations, just like the initial value for the energy in the space or the baryon number.

Or the number of space-like and time-like dimensions.

Or their inherent topology.

Not that it matters, as the point of what I suggested is that it's an analogy for all objects within the space observing the same relationship, and the implications thereof.

> Where we can see it?

In the relationship between distance and redshift. More distant objects move away faster, the further away the faster they move on average, and that relationship best matches "accelerated expansion" than any other model.

Or, more locally, it's (perhaps by coincidence) about the right level to explain the moon's orbit slowly getting bigger.

> In case of Steady Universe model, light just changes it's properties over time, for example, because gravitational waves are stretching photons and photon beams. Gravitational waves are produced by massive objects, which are orbiting each other.

Great!

Unfortunately for you, those gravitational waves can't act anything like the ones predicted by GR which we've actually observed, because those are far too weak (or spacetime too 'stiff', IIRC).

GR has known weaknesses, to be sure, but they're all annoying beyond any observations we've been able to make, and people really are looking as it's considered both important and prestigious to find a way to tie it and quantum physics together properly.

In the meanwhile, the same equations for GR describe the (just about) detectable gravitational influence your body has, and the various demonstrations of gravity influencing the flow of time and path of nearby light.

IIRC, the best atomic clocks are just about at the level where an extra 100kg sitting next to them can change the last digit relative to another otherwise identical clock, but I'm not sure how long you have to sit there.

They're definitely good enough for it to matter which floor of a building you put them on.
> Are you sure? I see scan lines (of the NTSC/PAL variety) when I zoom in.

The electron gun is still having to hit discrete pixels on the screen. Rather than drawing the image line by line, it's traveling at angles to render the image. It wasn't so much that these graphics couldn't be done with the NTSC/PAL standard (although you would have an increased backlight), but it was a limitation of game hardware of the time. Defining a series of points to draw lines between required less memory than sprite-based graphics.
Fun essay.

I agree that guns remove the escapist aspect, but not that it foretells an impending industrial revolution.

The world simply won’t have coal nor petroleum; and schools of magic are competing with and dwarfing chemistry and science, and that’s enough to kill any momentum on industry.

It’s a world where industry can only be at a small scale.
Good article in general, but I have some hairs to split.

First, since my D&D party's skin was saved in their last adventure by a lucky critical hit from our party's arqebus, I don't agree that (high) fantasy avoids gunpowder altogether. And we're the good guys, right? But on to more serious things.

> With a bow, or even a crossbow, skill and personal investment requirements are significant; by contrast, musket drill could be learned in weeks.
> ...
> Likewise, short bow, long bow and crossbow are tactically extremely similar.

Nonononono.

Longbows required extensive training (quoth one King Edward, "If you want to train a good longbowman, start with his grandfather."). Crossbows, once manufactured, could be taught to your average vassal in a day or so. This is one reason that the Catholic Church tried to ban them in 1096 [1], as an untrained peasant could take down a noble armoured knight (at least in mail rather than plate armor). While there were highly trained crossbow armies, such as Genoese mercenaries, the crossbow could greatly increase the deadliness of your average conscript - in less time than it takes to train someone on the musket. Whether you had the resources to outfit a large unit of crossbowmen was another matter, but if you could, training was not the bottleneck.

The average crossbow these days shoots something in the range of 60 yards, with high-end models getting "up to 100 yards" according to one manufacturer. If we allow for past war crossbows being beefier constructs - they had windlasses to help load them, after all - then maybe we can add a bit to the maximum and say 200 yards shooting in an arc, but the Book of the Crossbow [2] suggests an effective range of medieval crossbows of around 40 yards. After all, you want your shots to kill, not just go "plink" on someone's helmet.

Longbow range is generally given as something like 500-1000 feet, so 160 to 320 yards approximately - Encyclopaedia Britannica [3] gives an effective range of around 200 yards for the longbow (but this was presumably against massed targets, in the "rain arrows from the sky" style). That's more than double what you're getting from the crossbow.

So tactically, longbow and crossbow are very much not the same thing.

[1] https://www.wearethemighty.com/mighty-history/catholic-churc... (Note that I don't agree with the article's claim that crossbows had a greater _range_ than longbows. They generally had more kinetic energy on discharge (what we would today call "muzzle" energy) but _shorter_ effective range due to higher air resistance from thicker bolts. They were more handgun than sniper rifle, siege ballistas excepted. But they were very deadly at close distances.)

It also wouldn't be trivial from the hardware side. LoRa/NB-IoT/long-range low-speed low-power protocols generally use ISM band of 915 MHz in US and 800 something MHz, with some using 400 ish MHz. That will physically require a completely separate RF path than the 2.45 GHz and 5.8 GHz which WiFi uses. (No, even "integrated wideband transceivers" like AD936x have 1) unusably bad isolation and 2) filtering requirements)

This is also disregarding that "a few extra modulation schemes" is costly to implement. Narrow band schemes (like GMSK) are incompatible with wide band protocols like LoRa or WiFi with spread spectrum/chipping or OFDM. (at least if you are interested in the same performance to price ballpark) Of course many things nowadays use digital baseband so it's in theory flexible, but the front end is still a major limiting factor, unless you use many-GHz RFADC/DAC which still suffer from wide vs narrow band problems.

Also, most long range protocols are meant for ultra low power applications like smart-ag or energy harvesting which WiFi does not support.

Considering the existing amount of congestion with WiFi, if we want to increase range further, we'd likely need more chipping codes to fit in the same frequency allocation, which will increase the noise floor for everybody, thus reducing the range... etc
Layman thoughts:

(1) with enough high-quality training data, «AI» models should be able to output H265 / H266 / AV1 directly, can achieve simplicity and reduce artifacts by skipping an inferior compression step and leveraging temporal elements

(2) if AI video compression (as demoed by nvidia) becomes standard, the training data and generated data will become [more] «AI-native», boosting these efforts by miles
But doesn't society also benefit from both the formal and informal part of the conference? Is it worth levelling down?
To me, it seems like bubble sort is almost inherently easier to reason about.

One iteration of bubble sort is: find two elements in the wrong order and swap them.

One iteration of insertion sort is: find an element out of order, then find the location in the array where it should've been, then move all the items between those two slots one slot ahead, then insert the out-of-order element into the now free slot where it belongs.

Admittedly, insertion sort is pretty intuitive, since it reflects more or less how a human would instinctively try to sort a list; take an out-of-order element and move it to where it belongs. But when translated to code, I think it's very hard to beat "find two items in the wrong order and swap them".

In general, I agree. I also found that "let the remote audience ask questions and participate in discussions via zoom etc." pretty much didn't work except for some smaller events. Yes, they could load questions into a queue which is something but, then, Q&A in a large conference session isn't great under the best of circumstances. "More a comment than a question" :-/
100% agree. A tangent to this which I’ve found striking when talking to friends in other professions, is how spoiled I’ve been as a developer. I’ve _never_ had to apply for a job. Whenever I’ve been ready to move on I’ve just flipped that “open for suggestions” switch and within a couple of weeks I’ve signed on for a new company.
As far as I’ve heard, that doesn’t happen in other industries. People work their asses off _looking_ for work.
Even if I also sometimes get annoyed with particularly generic outreaches, I check myself and remind myself how lucky I am to have that problem.

Is this written by a recruiter by any chance?

Of course recruiters can be useful, but you need to understand their limitations. They just want to shortlist five candidates to a prospective client, and beyond this, they don't care.

Of course, they can be helpful if you end up on their shortlist. However, I would also recommend applying directly to jobs. Recruiters do not care if the job you are applying will result in working for the devil himself, as long as they get their commission.
Tolkien was pretty much a niche read until it blew up from the screen adaptations, and maybe a little from the earlier hobbit adaptation. Fantasy has never had a better time than right now. So it will inevitably decline, I think, but should remain more popular than historically because of video games, etc.

Look at baulders gate 3 success. We may have read more, but when our kids, neighbors, nieces, classmates, etc, say they're enjoying it, we'll have a long list of suggestions. If we the nerdiest can't keep the momentum going, that's on us.

But if you want to blame anyone else, blame film industry for churning out crap instead of scouring literature for new stories worth telling.
More people should read Disability Visibility.
TL;DR: I suggest you ignore random recruiters.

Recruiters are paid to get someone (you?) to a position: it is not their job to care on whether that's the best choice for you.

The recommendations on the article require quite a lot of time managing recruiters, and it is only a matter of time, if everybody starts using these "techniques" that recruiters will devise defenses...

So I'll give an opposite view: ignore random recruiters. Use the time to setup alerts for companies/jobs you really aspire to get to, and fight for those instead.
> Additionally, the 68k to PPC transition happened when Apple used a totally different OS, with a different application file format (hfs dual fork file, vs .app directory bundle).

What? The 68k to PPC transition was from 1994 to 1998 (versions 7.1.2 to 8.1). The NeXTSTEP-derived Mac OS X (which uses .app bundles rather than resource forks) was released in 2001; though there were betas and developer releases as early as 1997, the OS transition is still distinct from the 68k to PPC transition and there were quite a few PPC-only releases of the pre-OS X Mac OS.

parallel is great but its default behaviors never quite seem to match my needs, so every time I use it I have to spend some time consulting the man page. Fortunately, the man page is more than up to the task.

But because of the mini learning curve on each use and because I find I need a little more boiler plate to use parallel, I use xargs -P more often, only using parallel when I need its special features (e.g. multiple hosts or collating the output streams).

Oh also, parallel itself can be a bit of a resource hog. (Obviously that depends a lot on how you're using it-- but I mean in cases where xargs' usage is unnoticeable I sometimes have to change the size of my jobs to get parallel out of the way).
