I've never had a problem in my entire life with wired keyboards, mice, or headphones. I've had probably aggregate thousands of separate instances of problems with wireless devices across the last 20 years.

Wireless is awesome for when you're on the go, but if you're going to be sitting at a desk for hours anyway, wired is life.
> Just to be clear, your wireless mouse, keyboard, headset, and network connection are not making use of light through air

Yes they are. “The terms light, electromagnetic waves, and radiation all refer to the same physical phenomenon: electromagnetic energy.”

https://science.nasa.gov/ems/02_anatomy

Light and radio are both electromagnetic energy. Radio waves and light both propagate at the speed of light. The speed of light in a vacuum is a universal constant. The speed of light in various mediums is always slower. Among copper, air and glass, light/EM waves will propagate the slowest in glass and the fastest in air.

https://en.wikipedia.org/wiki/Speed_of_light

> cannot make use of light through air even a fraction as efficiently as light through fiber optic cable, due to a guaranteed minimum amount of light interference in air that a fiber optic cable will never have, right?

No, not right. As someone else pointed out a point to point link through the air will have lower latency than fiber (glass or plastic).

Whether or not a signal can be carried accurately and error free through any medium involves concepts beyond a basic understanding of the speed of light. But in the real world one will encounter reliable well designed wireless links and poorly performing wired links.
I've worked for 4 startups previously almost all very early stage. 1 was aqui-hired. It takes a lot of patience, a company might get totally nixed by black swan events like covid :)
I bet “should begin with the letter E” was one of Microsoft’s requirements for selecting a new browser name so they could continue to use IE’s familiar “e” app icon.
Maybe because very few people have even heard of this, much less used it?
For my personal setup: Rode NT-USB Mini (https://rode.com/en/microphones/usb/nt-usb-mini). It also give me a physical volume control for attached headphones.
Ah! You're right, I totally missed that the commenter was griping about UTC dates as opposed to datetimes. I agree, a "UTC date" is not a clean concept. We can talk about Julian or Gregorian dates, but those are independent of time scales like UTC or TAI or UT1.
That argument doesn't make sense. Nuclear power plants are capital intensive; countries that would have a higher tolerance for safety and environmental shortfalls would find nuclear power too capital intensive to be financially viable.

"True Faith" is also notable for having a really fun music video, which is often projected during their live shows: https://www.youtube.com/watch?v=mfI1S0PKJR8

Picking favorite New Order tracks is especially difficult since many of their singles have multiple mixes, with substantial differences. For example I always prefer the gothier 12" remix of Sub-Culture, or the dancier Shep Pettibone remix of "True Faith". And meanwhile with some hits like "Bizarre Love Triangle" there are far too many versions to even keep track of...
> Wind power is totally underutilized in the shipping industry

The shipping industry was 100% wind powered, with very mature technology developed and tried during centuries, and thousands upon thousands of experts in the area. Why do you think the whole industry switched to engines?
Please explain. Genuinely interested. Thanks.
Both is the answer. I'm using wireless if I anticipate whether I'll need mobility sooner or later, and wired as backup and other cases.
It'll match couples based on predictions of how subservient to machines their offspring will be.
ok editing my reply here too thanks
Have you suffered excruciating pain for multiple days in a row? Non stop? Like so bad that your muscles recoil in horror that then causes even more pain in a recursive loop of horror?
With engineering it's the opposite way around.

So if you hear a STEM person say either, ask what their job is.
ChatGPT is the fastest growing consumer product ever created, by a large margin. That’s pretty successful.
More likely is that the optical modulator which adds the temporal "vibrations" works not exactly like the theory predicts.
It wouldn't surprise me if that more or less is the plan. It's probably not particularly cheap but it probably beats having to install many thousands of kilometers of cables all over rural New Zealand.

But let's do the back of the envelope math. A typical 5G base station would use a couple of KW of power. My guess is they'd use ones with more range, which probably means more power. Let's call it 5kw. I'm not an expert but that seems a reasonable number. Maybe it's a bit high. Maybe it's a bit low. I don't know, I'm probably biasing to too high.

So, if you'd need to power that 24x7 using solar you obviously need some battery and enough solar panels to top those up even on the most cloudy days. If you have a 50kw solar setup, you'd be generating 10x more power than you need on a sunny day for about one third of that day. So you end up with roughly 3x more power than you need at best and probably some reasonable portion of that on average. On a bad day that might drop by a factor 20. So, you need probably at least a week or two of battery to play it safe. If you assume a complete absence of light, you'd need about 120 kwh per day. Of course that's not realistic. So it could be a bit less than that as you always get at least some power. A tesla powerwall would be not enough, a tesla megapack (~2.7M $) would probably be overkill. Probably about a quarter to a fifth of that would be plenty. Probably less.

Not particularly cheap but doable probably. Add a windmill to the mix and you can probably get away with a lot less solar and battery. Probably a few hundred thousand would go a long way and a few tens of thousands would be on the low end of the spectrum. Let's call it 100K per site plus or minus 25% or so. Doing ten of these cost a million. Doing 1000 of these 100 million. Doing 10000 of these a billion.

New Zealand is a 100000 square miles (to stick with your numbers and miles). So, you'd need about 40000 of these things. So a few billion. I bet there are probably multiple creative ways to get that number down a bit. So, not cheap but doable. At worst billions in cost.
> I remain a firm proponent of FLOSS, but I am also realistic about the value of truly great proprietary software!

This mirrors my own experience with JetBrains products, in particular with their Java IDE in large enterprise projects (4000+ source files). NetBeans kept freezing when I tried to use code search, whereas Eclipse seemed to randomly crash. I also recall the data source and MyBatis XML integration (with plugins) being better in IntelliJ IDEA as well - even though the startup indexing is slow and I also needed to increase the max memory for the IDE, same as with others (a few GB per instance). Aside from that I might just like the NetBeans UI a bit better but the language support isn't there.

This was a few years ago, but JetBrains still seems to have great code completion, tools to explore the codebase (dependency graphs, ER diagrams for DBs), as well as support for most of the popular stacks out there, which is why I use their Ultimate tools package with everything. Only Fleet was buggy when compared with VSC, but it was tech preview when I tried it. Oh and the PyCharm experience with Python and venv was a bit off when there were build errors (they weren't displayed prominently when you used the context option to install dependencies), but Python in general seems to have issues on Windows sometimes with compiling drivers or whatever.

Edit: oh wait WebStorm had issues with refactoring in a few thousand line long AngularJS controllers in one legacy project.

To me it feels like software like that should be free, but sadly that's not the world we live in. I personally lucked out with their student offering, graduation discount and recurring discounts. For smaller projects I still do some editing in VSC, not a Vim/Emacs user personally. Cloud based dev tools seem... interesting?
Yeah, let our imagination run wild and suppose this happens.

How would you deal with the Crimeans who got overly cozy showered with Russian Oil/Gas money?
If you wanna get into the weeds, it's "disparate treatment discrimination" that requires “intent,” whereas disparate impact discrimination does not.

But this is maybe a useless discussion about the technical requirements. In practice winning a case without proving intent is extremely rare from what I've read

Please correct me if I'm wrong
The current crop of services and pdf chatbots that you see going around using "train" on your own data aren't doing anything of the sort. They are essentially finding relevant sections of your docs and stuffing that into the prompt context window. Think of llama as the trained base model (not particularly useful for any one thing by itself) and alpaca is a fine tuned variant of that to give it chatgpt like "powers".
Password-crackers and metadata used to check welfare users' relationship status
How do they have nothing to do? They’re part of the feedback cycle. They’re the hand that feeds.
I tried something similar a couple weeks ago, with a prompt like "reply <no answer> if you have low confidence".

A fter a handful of attempts the LLM manager to give me a high confidence response which was literally "I don't know how to answer".

Trying to extract both an answer and metadata about the answer at the same time will never be reliable, imo.

Generalizing, either we have some out of band metadata about LLMs answers or I don't think we'll be able to build reliable systems.
This. Never had any issue with my wireless headphones, but Teams insists on picking random outputs and inputs even from one call to the next.

The only logic I've found is that it prefers devices that handle both input and output. So, it works OK with my combined headphones + mic, but if I want to use my external dedicated mic + headphones without mic, I have to fiddle with the settings whenever I join a new call.
Article titles that consist of "yes/no" question should be legally obligated to include the answer. Though, the vast majority of the time, you can just assume the answer is "no" and keep scrolling, regardless.

Still, such open-ended questions, by their very raising, suggest something occurred that may not have, essentially contributing to misinformation and uncertainty. Without a person expending the time to go to the site and read the post's content, the uncertainty remains, and one may go on thinking "maybe" something happened, that didn't. Considering the article in question is published by "Federation of American Scientists", a group I'd expect to have a high standard of quality and factual precision, I'm surprised they permit such a lazy and irresponsible article title.

Actually, I clicked into the article so I can find out who the author is, so I can ask them to revise the article title. Whether they do or not, I figure I might as well contact them, since I already spent so long writing this comment :P

BTW, I saw this HN article hours ago and basically just spent all day thinking there was a US nuclear accident at a Dutch air base, because I saw the headline and didn't click through to the article at the time.
>What you are arguing is that we should be a low trust society

Who's "we"? Not everyone lives in your country.

If you're talking about the US, that's definitely a low-trust society.
I definitely didn’t think you made it up. And yeah that site does match 20 Adderall XR to 50, which is very odd because it also says 20 of the other Adderall is too high for a Vyvanse equivalent. For Adderall XR it also lists a maximum dosage of 30, which is not true. I think they’re treating the XR as two doses, and halving to accommodate that? That is definitely not how I’ve ever had it discussed or prescribed by my doctor, or fulled by a pharmacy. And it’s inconsistent with Vyvanse which is also XR and always treated as a single dose.

In any case if you were taking Adderall XR “20” and it was actually two doses (40) that would be equivalent to the Vyvanse.
I'm not too fond of seeing or using big headphones or even smaller earphones (wired/wired) during video calls. I believe even Apple haven't found a design that is more natural with their AirPods. I also don't yet trust wireless for audio.

I have a much cheaper version of those costly wired earphone studio monitor that musicians used on stage/studio -- the one where the wire goes around the ear and hidden behind. I sometimes combine that with a wired Lavalier Mic. Both of which are tucked and hidden under my table for quick and easy access. I have very clear audio and people on the other end have told me that I'm very clear too. Very discrete while audio being clear on both ends. I want to set up something similar but less messy for travels.

However, in most common day-to-day meetings (teams, quick calls), I default to an XLR pointed from above the display.

Efficient WebAssembly-based vector math engine for JavaScript/TypeScript
Hi, HN!

I've been building a suite of developer tools for developers building AI products, and last week, I decided it might be a good idea to start open-sourcing distinct components of the suite that may be useful to the public.

I've just open-sourced [1] and published the first component, which is a minimal and efficient vector math library for JavaScript/TypeScript I'm calling Vek Engine (see: something about two hard things in Computer Science).

Since this is part of a larger product suite that's not polished or even close to ready for public consumption, I had to carefully extract a slightly slimmed down version of the library, but hopefully, it's useful to someone here. One primary/obvious way I've been using it is to manage embeddings.

I haven't had a chance to explicitly document the library, but for now, the tests [2] are pretty thorough and should be sufficient for understanding how to use it.

Have fun!

one thing that is not mentioned in the article, is that for states with mandatory eprescription , this is now an absolute nightmare.

Patients are forced to call the overwhelmed PCP , to get a new RX to be sent to a new pharmacy, while the patient is busy with life/work....in the hopes that patient meds will be found at the new location when the RX finally arrives to the pharmacy. And then patient must repeat the dance in 30 days!

It is absolutely bonkers.
After six months of using a Logitech g pro x superlight, i haven't seen any degradation in my performance in video games and even have improved a few of my records on FPS Aim trainer (Ranked top 50 in a few popular scenarios). There are people who reached the #1 world rank using that mouse too. I have played at high level for many years with a Microsoft Intellimouse 1.1 which had more than 10 ms of input latency despite being wired. I have noticed that the amount of frames per second has a much higher influence (If you shoot on a target then move the mouse before the next frame, then you may actually miss the target because the game may handles the mouse moves before the shoot event).
Regarding Fishy Finances
I gotta say I have found Mullvad to be refreshing; they have good apps (you can get it running on most Linux systems with very little work) and I don't have to remember a password, just an ID number.

Stupid simple stuff, been using them for a long time (and guess what? no info shared, they don't EMAIL me every time they have a discount for a 3 year subscription discount like some VPN companies)

They just seem very honest and straight forward with their marketing. Never a bad moment.
For the original hobby niche of small electronic projects where a microcrontroller with wifi will suffice, the ESP8266 / ESP32 have been quickly overtaking the pi zero. Of course it's not really comparable and there is the Rpi Pico as a competitor but I find the ESP32 much easier to work with. It's also much cheaper (not to mention the 8266)

For heavier usecases that really there isn't as much of an alternative. Many other boards like the pine64, beagle and orangepi, but their ecosystem lacks sophistication.
> ...are not making use of light through air, and your wireless network connection cannot make use of light through air even a fraction as efficiently as light through fiber optic cable...

There's a clear misunderstanding here.

Light and wireless signals used by mice etc are the same thing though, just at a different frequency. They propagate at the same speed, the speed of light, which ironically is slower in glass.

Wireless signals in air travel faster than light in a fiber optic cable (and faster than electricity in copper).
They didn't want to accept $15M from the original trial, they demanded a retrial and ended up with $3M.

Should have taken the $15M. I'm not sure $3M leaves anything for the worker after legal costs.
These foolish projections never account for accidents, destroyed uninhabitable lands, or nuclear waste disposal which currently costs infinity in the USA since all waste is stored at reactors and guarded, forever.

You really have to be foolish to believe in nuclear power ...

Avoiding SSO to keep access even if you loose access to bigCo email has been working well, but unfortunately more & more websites are moving away from password to instead verification code in the email.

Sure there are advantages to it, but if the email is bigCo, it effectively has the same drawbacks as SSO from same bigCo (i.e unfair account suspension, you're screwed)

With email+password, even if you lost access to let's say your Gmail, you can still login with that Gmail address and your password and go change the email in your account profile.
I've seen many systems that disallow the password reset flow when you sign in via SSO, since the expectation is that you as the service provider are not the authority for the user's identity.
Weird headline. It's really more about blue-collar vs white-collar jobs. It's not like there aren't blue states with lots of working class folks.
I got a ModMic USB after being pretty unhappy with the samples of mic quality that I heard from headsets. I have received a number of positive comments on my microphone quality after switching.

It also gave me back a hardware mute button, which I missed from prior USB headsets.

I have a preference for just USB wired hardware. A number of laptops and sound card addons have some whack spatial audio stuff they do in their chipsets that you have to go trawling through forums to find out how to disable.
Since the USB devices bring their own hardware, they get past this a bit.
I think that metabase example is telling, though. Is it actually easier or better to write out a whole paragraph describing your query instead of clicking through a few drop-downs? Far worse, those drop-downs are not only expressive, but they have ostensibly perfect precision. With an LLM UI, you can find yourself endlessly prompt engineering your long paragraph. AND, that's only if you've realised that the LLM didn't give you the correct result according to your query.

Please don't let LLM's become the blockchain folks. It's exciting stuff, but I really think people have come to believe that LLMs are actual AGI.

I don't know about that. I've seen enough websites that have specifically removed social logins, so it appears that there is an awareness that the feature was "strings attached" kind of thing. And no, these are all tech oriented sites I've seen this on either.

This is all very interesting (and makes me check out Parquet) but it's painful to see how the text goes to great lengths to describe how it avoids common problems and what they are, but doesn't lose a single word on... how they actually solved these problems. What is the actual boolean type? Which encoding are you actually working in? There's nothing concrete but an implication that it's also compressing data?
