I am working on my HAM General-class license. I have young and non-engineer friends who are into it. It is mostly interesting to them because they have never done something highly technical, and here is a relatively approachable technical hobby.

However, I'm decreasingly enthused about HAM. I got my license so I could interact with devices that I wanted to build. However, there are almost no use cases where HAM helps. I cannot build something cheaper, or make it more effective than a commercially available product. It's only at the extreme, un-useful cases that HAM becomes a thing. (Want to bounce signals off the moon?)

What I'd like to see from HAM:

- More, different competitions. Long-term monitoring, stealthy side-channel transmissions, digital and analog networking competitions (like hackathons: Get a signal from A to B with minimal loss / delay using teams in disparate areas of the country --- internet OK), recovery games (set up a network serving x users with max datarate or voice capacity using this equipment), or encoding / decoding games, and so on.

- More support from local governments and infrastructure. I want to know where to sign up to be useful if telecommunications suffers a hiccup. If that is not useful, I want to know and be told how to be useful (esp studying different technology). Some certifications beyond HAM, and specializing in different niche areas would be nice.

- More training on HAM-adjacent technologies. To be useful / innovative requires knowing the telecommunications space, and sticking to SSB voice + FT8 for DXs is great, but not helpful when trying to understand telecommunications and make an impact on the world. God forbid a disaster did happen and the HAMs showed up with their 10m antennas and were useful for 30 minutes until the Verizon tech arrived. It'd be more useful if they could bridge 3G / UHF by setting up an adhoc repeater network to actually extend the range of whatever equipment didn't die in the zombie apocalypse.

For example:
In the IoT area, I thought for sure HAMs would be front-and-center with new mesh networking technologies, WAN, etc. But no, we got another AWS product with minimal device-device communication and called it a day.
It could be. Maybe there will not be more reviewers, but the process of reviewing could be faster. For example, in the kernel there are inline functions, which accept a constant (known at compile time) integer argument, and they make a switch or loop over that integer. The trick is to force compiler to inline function and to throw away most of switch's cases, or unroll loop completely, or make some other optimizations based on knowledge of the passed integer value.

Such a functions are exported to a public kernel API sometimes. So any kernel developer could call them. It make unavoidable a mistake of a programmer, when some of those functions was called with an unknown at compile time integer value. It is not a bug as it is, code would compile and work nevertheless, code would be bigger that it could be, maybe slower, that's all. But reviewer should be finding such a misuse of API.

It is just one example, linux kernel uses a lot of tricks and exposes it via APIs, reviewer must be aware of all of them and to check everything by itself.

Compare it with Rust. In rust one can encode a lot more limits on the right use of an API than in C. Encode and enforce. Even when rust sometimes cannot do it, rust have nice macros, instead of C's macro-horror. So a lot of mistakes that could be made with C, could be avoided with Rust. So it would be easy to review code, it would take less time from a reviewer to review code.
Yeah but the idea is to decentralize and disperse management of the money.
> It only addresses religious persecution

SO you agree that Ahmadiyas are persecuted. They are a religiously persecuted because their sect is being persecuted.

so CAA clearly should have involved them because any secterian persecution is by default done via religion.

They're not being persecuted for owning a PlayStation in a country of poor right?
> I'll assume that's not the case

Thanks, that was actually the right answer! (And those assuming otherwise are not just getting the wrong answer, but I'll point out are breaking the rules[1] here, too.)

The C++-to-Rust background is what I suspected—but the reason had nothing to do with being dismissive about not having the right buzzwords to prove you're smart and well-rounded. (This isn't a job interview, folks, geez.) My instinct was a presumption of deep familiarity.

When I mention Rust having the marks of a being from the C++ world, I'm referring to a property of the language that it shares with Swift. When you say you don't see much similarity, my suspicion is that your first consideration is language semantics and the new affordances, and so when you think of Rust and C++, you're seeing foremost all the ways that they're different, rather than seeing the things that they share. I saw where Hejlsberg once said that he doesn't get why people draw comparisons between C# and Java, and then gives a list of reasons—where those reasons show that his main focus is similar, i.e. he focuses on the way that they differ (and maybe in his case, all the things that he "fixed" with C# in comparison). One of your sibling commenters writes that "Rust is an ML-family language dressed in a C-family syntax", but that's a little off the mark. Rust certainly has a C++-style syntax, but aside from curly braces, idiomatic Rust looks alien when compared to C.

Congratulations, you just killed collective bargaining. Now workers have no effective way to demand changes to their workplaces.
The majority of them which happens to also be “enough of them to catch any widespread attempted fraud by printing ballots different than what the user picked”.

Force a time delay that’s long enough for a typical user to validate their picks before proceeding and you might bump the figure some.
I thought so too until a friend showed me his small telescope on his apartment building right downtown. And we could see Saturn's rings clearly! I would never have guessed it could be done in the middle of a major city.
This might have some benefits but it would certainly not make politics less polarizing. See countries that have, or have had, a National Service.
Ahmadiyas are minorities in Pakistan as are the Rohingya in Myamnar.

also if you think that Rohingya hsould not be allowed because Myamnar was never a part of India, then Afghanistan was also never a part of India, so why are Afghanis being given fast tracked citizenship of India?
Here's another relevant comparison between Nordic countries and the U.S.

Country | Labor union density
Sweden | 66.1%
Norway | 52.5%
Denmark | 67.2%
Finland | 66.4%
Iceland | 90.4%
U.S.A. | 10.3%

Legally mandated minimum wages are needed in the U.S. due to the lack of strong unions.
I think that is where creativity and imagination come in. I'll give an example I encountered recently. Northgard by Shivo Games. It is absolutely brilliant, thematically and mechanism wise, a re-take on the traditional RTS.
Early voting is available over the weekends in many places. A weird amount of people don't realize it's a thing and believe they have to go on election day.

>Human-like is not the only way to approach doing or learning.

I would also say that we shouldn't agree that there's an irreducibly human-like way to do things that only belongs to humans. The things we think 'belong' to humans, such as our intrinsic bike-riding ability, may well turn out to be not intrinsic at all, and able to be modeled in all salient ways by a machine.

I think if we allow that distinction to be made, and proceed to argue that machines can learn in different ways, it allows a very strange human-essentiallism to go unchallenged.
I don't think it's jarring to use an OS modal, if that modal is the one that almost every app already uses: [1].

Perhaps this could be the default way of interacting with the clipboard, and then apps that want to be able to read it a different way (e.g. Google Chrome wanting to be able to offer you a "Go To Link You Copied" button) could request an additional permission.

Right, at that point we're getting into semantics. If the votes aren't counted correctly, and a group of people are doing it somewhat systematically, I consider that fraud. Given that they were students (and the overall result did not change dramatically), judges were lenient and basically said "mistakes happen, no hard feelings".

I have little doubt that it would have been quite different, had the situation been reversed, but I don't care enough to argue about it with you.
Except that kids tend to destroy things (the binoculars obviously, not a trowel), tend to be violent with and throw things (a real gardening trowel is heavy and could injure their sibling for life), and quickly lose interest in things (they forget about the $20 binoculars long before their lack of quality is apparent).

I mean it depends on the ages of your kids... but there are very good reasons most toys are cheap plastic. It didn't just happen accidentally. It's a feature, not a bug. (Except for landfills, of course.)

> Also most of the good Lego sets are either cars or airplanes.

Isn't that just expression of your topical preference? The shelves are full of lego sets that are neither cars nor airplanes and I really don't know what is supposed to be wrong with them.

We tend to buy lego when there are discounts which does remove bests sets and there still seem to be enough choice.
> Northgard applies DRM even to single-player modes. You cannot use them without simultaneously connecting through the Steam^W GOG client.

I'm not seeing anything about this in reviews or elsewhere on Google? The GOG page itself states:

> Please note: The GOG Galaxy Client is required to access online features for Northgard.

But, offline singleplayer seems to work fine by all accounts. I'm actually a bit tempted to buy the game to verify absolutely.
Present Bias: Critical Obstacle in Habit Formation
I argue that the clipboard shouldn’t be given any extra levels of trust because it’s current level of trust, very low, is the correct amount.
Dad always told me the smartest people he knew were Hams so I figured why not. Skimmed the book, used the flash cards, and got a tech license.

In short, it sucks. Some observations:

- the exams are oriented towards RF knowledge and will weed out anyone who just wants to go on the air to talk. They should really restore the novice license. Give it the same privileges as technician with no rights to broadcast over 10w or construct towers

- there is MASSIVE underutilization of spectrum. not just at the tech level due to inefficient coding but in general, the airwaves are not busy at all whatsoever. I live in NYC and there are rarely more than a dozen or so people on across the entire tech band at any given time.

- conversations are dull. the weekly nets can be interesting but pretty much the subject of conversation always revolves around call quality or someone's rig or something to do with radio. It's boring!

- proprietary. all the digital modes employ proprietary protocols or proprietary codecs. brandmeister is closed-source. echolink is closed sourced and rarely updated. DSTAR is proprietary. DMR isn't proprietary but the vocoder is. want to setup a repeater? sure, go pay a shady motorola VAR a few bucks and he'll sneak you a unit and user manual.

> That (including healthcare) is what you have in Europe if you don't work at all.

I assume that this refers to unemployment insurance, which is often provided for a limited time, and/or requires you to be actively looking for work. One of the issues with the European model of social insurance is precisely that those who are working at the low-end of the labor market are not included in this kind of redistribution. Enforced unionization and strict labor regulations are then used to make up for this, but that means losing flexibility precisely where it's most needed. You can witness the outcome in places like France, where the poorest and most vulnerable are locked out of the labor market altogether leading to huge society-wide issues.

> As for cutting the defense budget in the US, I'm torn.

You could cut a lot of the defense budget in the US if the US's allies started paying their fair share. Of course, paying for US allies' defense comes with foreign policy advantages for the US so perhaps this arrangement is also "fair" in a way.
There is always a population of military veterans who pose a threat to order. When I mean always I mean Rome, I mean feudal Japan, or Hitler's first stormtroopers. Closer to home we have had black nationalists, Tim McVeigh, and other troops bring the war home with them. Now there are 'boogaloo boys' who seem to hate both blacks and cops.

Most veterans are not like that and return to private life and public service in ways adequate to admirable, but it does show that national service is not universally civilizing.
My Thinkpad comes with a physical lid that works perfectly and is in no way inelegant.
I think Google's warning definitely applies to Clojure.

Most json libraries will convert string keys to keywords, and they're not weak references.

An attacker can probably just send a few dozen gigabytes of random json to the average Clojure app and it's going to go down.
If Zuckerberg was an evil genius, this would be the way to go. (For the record, I don't think he is a genius).

Refuse the call for moderation/arbiter position of political speech until the pressure becomes really overwhelming. Then seemingly very reluctantly give up and flip 180.

Now there is Zuck that is the “arbiter of truth” in political speech. It's hard to notice anything but positive change at first.....

Just voted yesterday: distancing rules in place, the gentleman runnung it didn't touch my driver's license, gloves available, masks required, and one older gentleman wore a face shield. Fairly safe and quick, though I imagine it might be more difficult and crowded on election day.
Windows on the desktop is a completely different can of worms. For example, I installed a small application last week to take screenshots of my entire screen every so many seconds and it was then that I realized the whole installation process (there is no installation process, just a simple executable with a config file in the same directory) and execution required zero root privilege.

Technically, any application (at least any application that lives in the system tray) can take screenshots of the whole screen as often as it likes. You can probably imagine it doesn't even need to store it on disk. It could just do some quick computation and send it to whoever.
you are acting as if the BJP gave India the RTI. Congress gave the country RTI.

and bjp has been systematically dismanteling RTI step by step.

We won't have a functioning RTI in a few years.

and the existing coverage of RTI in India is abysmal. This you'd know if you knew and read the facts. the govt has severely cut funding of RTI

63% cut in funding of RTI and CIC, both systems who are responsible for transparency.

Just because US/Wisconsin could not get it done does not mean no one can get it done.

USA had much higher costs, even outside of population centers, and too much dependence on tax shelters. It may not be the same in india.
Are there studies that have proven that a citizen's psychological profile / attitude toward government aren't impacted by mandatory national service?
I understand your point and it is perfectly reasonable. But Trump hasn't actually interfered in the CXOs life right? they get their massive tax cuts and all. so I thought they'd be happy with Trump.

Ha!

Well, generally, it's adults (who have cash) who give children (who don't have cash) the cash.

I've never heard of siblings giving each other cash, that's really funny. :) I mean in my family, us siblings never exchanged gifts at all until we were adults with our own income. Gifts were always from adults to kids, not kids to kids.

But when I was a kid my aunts and uncles obviously didn't have a clue what I was into or wanted. Cash would be wonderful -- the whole experience of figuring out how much, what my options were, going to the store, picking something out, having it be linked to not just one but multiple family members...

Cash as a gift, for kids, is honestly pretty great. A million times better than the usual itchy sweater and socks from grandma that I could never wear, unfortunately.
I'm not entirely sure why you're being downvoted because I wouldn't consider your comment here that objectionable. And in fact you're right -- you did not say anything about Crimea/Tibet; that wasn't so much directed towards you in particular but an observation I was making about a lot of others I know who have said the same thing. It was a bit hand-wavy, and perhaps I should have left it out.

Thank being said, your original comment -- which is what I replied to -- was not so much about highlighting inter-tribal conflicts as it is now that you've edited it. I just want to point out that I really do not appreciate you editing your original comment then replying to me without acknowledging that you've done so, effectively trying to re-write history. It's extremely disingenuous and not at all in the spirit of HN.
I am not saying all asset classes ought to be as volatile as stocks are. Investors should have choices about the safety of the investments they make.
AFAIK with package `reflect` it is not possible to attach methods to a dynamically create type. And that seems to be a prerequisite to be able to generate dynamic proxies at runtime.
I have a strong suspicion the OP is trolling, or at least his motives aren't obvious.

Check his profile.

He has people, or knows of people that can can likely help with this. He's a CEO of a an Accelerator and is not a newb by any sense.

OR... he's using gamification to find someone to hire to actually help solve this problem. If that's the case... Bravo sir!

We tried that system and it evolved into what we have today because there were obvious holes. The FDA didn’t create itself. Muckraking journalists (like Upton Sinclair) shines a light on the conditions which led Theodore Roosevelt to create the FDA.

Acting like the world of judicial regulation (which takes years and lots of money to see through) was somehow better seems like rose-colored glasses. Whether the FDA’s scope should be adjusted is a different discussion.
In might be computable in principle but not in practice for a long time, similar to how it is possible to simulate all molecules of air in one cubic meter (neglecting quantum effects), but not actually feasible in practice. Any argument for computability all needs an argument why a "coarse graining" or "effective model" of the underlying physical system exists.

In the case of transistors that is because all that matters are binary stable states, which reliably abstract over the complicated device physics. In the case of biological cells and neurons in the brain it is much less obvious what the reliable abstraction is. Right now a lot points towards "it is just a bunch of linear algebra and lots of data", but especially when we come to things like memory, online and few shot learning, the answer becomes far less obvious.

You can call CQ to see if anyone can hear you - maybe a partial solution.
Prioritization is not that straightforward. Every open source project has different sub-groups with different goals. While we do care a ton about generated code, there is also movement by other folks to work on the compiler speed problem. It has been a lot of work to come this far, and it will be even more work to get to a better place, but that work is underway. That's not even to mention that since rustc is written in Rust, work to make generated code faster can also make the compiler faster.

I'm referring to the rust-analyzer work, which is effectively an outside-in re-write of the compiler, if you squint at it right.

At the end of the day, rustc is a very large codebase, and has already undergone major architectural changes, and will be undergoing even more. It is not fast to steer a large ship in a new direction, but that is what is happening.

See https://pbs.twimg.com/media/ENC1ls6XYAEdKkv?format=jpg&name=... for a time I ran https://github.com/erikbern/git-of-theseus on the rustc codebase. Thank goodness Rust is such a good refactoring language.

Wow! At first I thought you had found a place where these two words occurred after each other but it seems to have been used a few times I must admit I have been wrong.

It is so nice when someone takes the care to actually provide evidence for their claims.

That said, today I would still say OSIs definition has won and if anyone presented me with code and claimed it was open source and it didn't match OSIs standard then I personally would be disappointed.

But I probably won't claim anymore that they are stealing our term.
Slightly off topic, I see D brought up incredibly consistently when Rust is mentioned on HN.. Is it just me?? (it's usually by walter themself but I digress..)
Very interesting. Something like this definitely needs to be done.

The angle here though, seems to condone a certain amount of shaming. It’s hard for me to not see this through the lens of someone doing a ‘mea culpa’ because they said something which upset people’s sensibilities, even if it was true.
I looked at this in the past and found it to work well but is (was?) missing a couple of key (to me) features:

* Per-podcast volume controls. One podcast I listen to (Data Skeptic) needs a volume boost
