Its unmodulated and nobody in the article or comments is willing to consider non-communications situations for both earth and alien sources.

Its entirely possible someone out there (us, or ... them) has a nice magnetron (or more exotic tech) pumped main engine or station keeping thruster that uses microwave energy to boost exhaust temp and thus specific impulse.

Then given that as propulsion tech, its possible that a boring engineering specification like "make the nozzle two space alien foot lengths in diameter" which is a nice round measurement to a space alien, is in fact 982.blah MHz to our measurements.

Certainly no one cares that their terrestrial microwave oven operates at 2.45 GHz, all they know is it pops popcorn. And in a like manner, some microwave boosted propulsion system, either an earth or alien source, might just randomly end up on 982.blah MHz but the number means nothing to anyone, its just what fell out of the thruster design reqs. Say I was building a microwave pumped thruster, I'd make the nozzle less than a tenth wavelength at pump frequency to contain any leakage RF while letting white hot plasma stream out. 982.002 MHz would be 30.5 cm in a vacuum, so figure my engine nozzle diameter would be about 3 cm across for minimal leakage. You're probably not going to get a huge amount of thrust out of something 3 cm across, so its probably a station keeping thruster at most not some main acceleration thing. Besides a couple hours of thrust would imply going very fast if it was a main thruster but some minor course correction / station keeping thing could run a couple hours. So its entirely likely some space vehicle had a pretty substantial failure of a course correction thruster.

Another topic no one is willing to discuss, which is a bit weird, is the old fashioned superheterodyne topology works pretty well, so 982.002 MHz is not the frequency of operation, its something in a local oscillator chain of a receiver (or transmitter) that works somewhat above 1 GHz. Another "where are the EEs" comment is 982.002 is possibly not an INTENDED local oscillator output but someone's class B or class AB output stage had a single transistor failure and what was outputing a great low distortion signal at 491.001 is now outputing an icky harmonic signal at 982.002 or similar after the output section failure.

Just because the 15th harmonic of the FM sound carrier of an old fashioned analog low-band VHF tv transmitter on USA allocation channel 3 could fall less than 1% off from 982.002 but doesn't prove it is the source and probably is not, the point is we could be observing a failure mode or unintended interference.
Agreed. I’ve set up my life to foster and form in person social interactions (and organizations to the extent that they help) in my neighborhood. It’s affected where I live, what kind of house I have, each weeks schedule, my kids education, and what jobs I’ll consider. But it’s totally the main thing that we have to work on as humans.
Another Obsidian user here. Pretty happy, but they have some rough edges to overcome still.

Surprised nobody's mentioned Craft[0]. Pretty amazing what they've managed to do in such a short time. Doesn't replace Obsidian for me, but I think for the "need a replacement for Evernote" crowd, there isn't a finer choice.

Yeah that'd be my expectation as well.

I think the hope would be that there'd be would be some limit to the willingness for someone to shift money into relatively illiquid assets (ie. cars) that aren't really that good of investments instead of keeping their money in equities and simply pay the tax. There's a balance to find there in the policy.
Just barely. It was possible to buy a PC with 2 or 4MB of RAM in the late 1980s, but you couldn't do much with it. On Windows/DOS, I think applications had to be written specifically with "extended memory" or "expanded memory" in mind. There were 2 incompatible "standards" for how to organize memory beyond 1MB.

On the Mac side, in 1989 you could apparently buy a Mac IIci for $6200 with 1MB or 4MB, "expandable to 128MB".
it's the natural progression of "someone's wrong on the internet" syndrome (https://xkcd.com/386/) as more and more people use and care about what happens on the internet.

I'd also guess the ratio of effort to page views is especially high with these sorts of stories. the outrage is already happening on twitter/fb/whatever. all you have to do is take some screenshots, summarize them, and maybe add a generic blurb about the greater context. you already know there's an audience, so there's very little risk involved.
I'm I alone in thinking the new timer app UI sucks? The old app where it used a spinner to set an alerm time and where I had N alarms that I could edit was simple and easy to use.

The new app where hour and minutes are separate text fields and where you can't edit an alarm you can only delete old ones and create new ones is utterly unintuitive to me and much slower and more error prone than the old one. Clicking in the hour or minute section is a much smaller target. Editing sucks. I want to set an alarm for 10:00 and it defaults to showing the current time 09:33 so I click the 09 and type 1000 but it only edits the 09 to 10. The 33 stays and I have to click the other side and enter 00.

To be snarky it's like some UX designer from Google went to Apple. This is not a UX I'd expect from Apple.

Meh. It’s vindictive, don’t get me wrong, but should he have just ignored this forever?

I feel kind of bad for the girl, but at the end of the day she said what she said. And maybe that’s a lesson for others.
I think it’s how you use anger that matters.

I am pretty certain there’s a huge log of people with the kindest faces who gladly closed their eyes on the abuse happening to someone else for a simple example.
Addendum to your point zero—test against a known live wire before _and_ after if you want to be really cautious. It’s possible the tester failed after your initial test, but before you checked the wire you actually wanted to test.

For example, imagine some batteries on the verge of death. They may keep enough charge initially to test right after being turned on but quickly die before you get to the actual wire under test.
Very neat how they bring the entire Nitro platform through the Thunderbolt ports.
I, personally, hesitate to characterize the lived experiences with policy choices of other polities as FUD. I understand that this is a deeply personal choice, and as such some might differ.
eMagic had a great collaborative DAW plugin in 2001 or so, the year or so before they were bought by Apple. You'd be in a shared chatroom with others, where you'd all see the same DAW view, and could play all the tracks. You'd record a new track locally, and then upload it. It was a cool compromise - in most use cases, you didn't necessarily need to record live, you just wanted to work on the shared project at the same time. I haven't seen that nice of a UX since.
> "I can't help but feel that this place [programming as a tool to make things] is a touch soulless."

I was somewhat interested until this gem, but then he lost me.

But I realize they're artificial categories; you can both appreciate elegant code while feeling satisfied with a useful creation. You can weep with joy over speed and efficiency while loving the delight someone has in using what you've made.

And really, this essay quickly becomes another 'there are real computer scientists, and there are the others', and I'm so done with that shit.
Hmmm... this sounds suspiciously close to "good" advice. I'm sure my grandpa would have done a spark test with the shaft of a screwdriver.

It means the divide between the rich and poor got even wider. The average person is poorer, can still buy basic staples, but is further than ever from being able to buy any assets and would need to work significantly more to build up the cash that would let them buy assets. It also means that the wealth of those whose wealth is primarily derived from assets has gone up signficantly more than those who have a mix of assets and earnings. Or to put it another way - the super rich are crowding out the rich from asset ownership. In essence making it difficult to build wealth.
Totally agree how snoring is normalized and probably shouldn’t be. I think there’s a lot of belief that sleep apnea is something that only happens to old or unhealthy individuals. Frankly for most people it’s due to airway size and back of throat muscle issues. Age and obesity simply bring it to the point where people are so sick they can’t ignore it, hence those who get treated.

I tell people it’s more like needing glasses. Most people just are born with the issue that develops over time. We don’t have hang ups with treating vision problems (at least not anymore)... sleep apnea should be the same.
Hm. No idea. Probably the worst material for the earthquake zone cities on the west coast tho.
Agreed and I'm especially concerned with how little people are taught about IT even though it's an important part of our daily lives. Specifically I think everyone should be thought about:

- cryptography basics

- how the web works (cookies, JavaScript etc.)

- how email works (MTA/MDA/MUA responsibilities, OpenPGP, S/MIME, maybe also SPF/DKIM/DMARC)

- TCP/IP basics

- how computers and operating systems generally work and execute programs

Though I'm not suggesting we should replace other subjects with IT.
The title of the article is "Physicists in China challenge Google's 'quantum advantage'. And the article does refute Google's claims of quantum advantage with references.

"But some quantum researchers contested the claim, on the grounds that a better classical algorithm that would outperform the quantum one could exist3. And researchers at IBM claimed that its classical supercomputers could in principle already run existing algorithms to do the same calculations in 2.5 days."

I'm not sure what you would change the title to. This one seems to accurately describe the article.
Reason is a right leaning (by media bias) libertarian magazine who loves free speech unless it goes against right wing ideas of who can have free speech. They drank the alt-right kool-aid a little while ago and began to spiral.

I honestly don’t get the rage with functional programming.

I find the hardest parts is GUI and user interactions, this is a place where storing state is natural.

Perhaps more on the server side functional programming is useful.

Can somebody meaningfully explain to me why there is such a swell of interest in this field? Is it just all the ML and data scientists buzzing about an approach that is naturally suited to them or is there broader implications? I wouldn’t have guessed that everybody on HN was working on optimizing multi threaded applications or any of the other valid reasons to consider FP more generally.
I agree the title is incorrect and needs fixing; actual title:

But - rightly or wrongly - Google's earlier claim figures heavily in the article also.
I agree. If we time travel and erased Mountain Dew from our collective history, we would be living in a different world. Possibly a significantly relatively Luddite one.
Not when you are looking for a workflow to make dealing with dotfiles faster and more painless. With the current (symlink based) setup, there is a hidden state you must hold in your head or else carefully inspect: the discrepancy between your git repo and your home directory. Maybe you forgot to link a dotfile, and that’s why your latest configuration doesn’t work. Ditto for unlinking a dotfile.

An sustainable economic system that promotes sustainable consumption and recycling.

That products are design for repairability and sustainability in such a system.

Third an economic system that is not built upon debt slavery but promotes individual freedom in the age of robotics.

That would be the three main things that needs fixing. Plus most countries needs four-seven weeks of vacation per year. This would promote healthier work life balance. Four day work week another one for work life balance.

Correct me if I’m wrong but ray tracing should iterate over every object in the general direction of that ray - and that can be less with things like AABBs and the like, while rasterization can throw away triangles with Z-masking. Is the former all that more efficient?

Why is state management a problem? Could you give a sample scenario? Have all screens be tied to an application session instead of managing page per page. A given screen stays put the entire session (although may be hidden or removed as needed). Its state would be hierarchically addressable & examinable, such as requesting "scopeA:screenB.panelC.widgetD.value". (Scoping clause optional.) I have some further suggestions for state and scope management that would take up too much space here.

The Oracle Forms client seemed to somehow pull it off. (It used a proprietary markup, not XML.) There are deficiencies with the Oracle Forms model, but it proved a browser-like GUI client approach can work. Companies loved Oracle Forms before Java ruined it. They weren't pretty, but cheap and practical to create and maintain. The Oracle Forms devs were 3x more productive than our MVC team and it took about 1/5 the code to do the same thing. Productivity died in CRUDville; we de-evolved. (Same for desktop VB & Delphi like tools, although they required per-PC reinstalls for app upgrades, unlike Oracle Forms.)
> Part of the reason is likely that black people, particularly dark skinned black people, are just harder to photograph than people of other ethnicities

If that were true, that would just mean photography-based systems are currently not good enough to work across any population that includes dark skinned people. Society should not, and cannot collectively wrings hands and say "Oh, well, it's really because of the photons" and go ahead make use of a provably unjust technology.

Thankfully, modern phone cameras can take great high dynamic range photos as well as low-light/night pictures - I'm confident to say capturing dark-skin is a much easier bar to clear (dynamic range can be much smaller if you only care for a person's face). The fact that good-enough technology is not used (or mandated), and the solutions providers & their clients decide on cheap(er) sensors with exposures that only work well with light skin tones... well, that tells a story by itself, doesn't it?

Our work did breakout rooms, so we had a “virtual happy hour” with 70+ people, then 10 other rooms with silly names like some animal and the name of some popular song, and you were encouraged to pick whichever you wanted. Resulted in a pretty even spread of maybe 7 people per room.

It was pretty cool because after we broke into groups I got to have some lighthearted small talk with the company CEO (I work at a 10000+ people company), which felt really neat to me as just a SWE a few management detached from execs, and I don’t think it would have happened pre-pandemic.

Alternatively, we had another “happy hour” organized by a different team that was like you said, 100+ folks with just a few of the most popular (or maybe just gregarious?) people cracking jokes and taking center stage, like a high school dance where a few people are dancing and everyone else awkwardly stands on the sidelines.

This is surely a sensitive topic and I hope I'm not being too insensitive here, but I've personally never frowned upon someone who has less hair than me. Even if my hair is thicker than that of most people, that only means I have less testosterone in my body that you. It means you are more of a man than I am. Everyone knows that. I say, own it!
Then the textures used for reflection is bad - not the ray tracing.
> That violates the 3-2-1 backup rule.

Ehh? Not really. All of these things we're talking about are components of our backup strategy.

If I wanted an offsite backup, its just rsync to some cloud provider (like rsync.net) or something. I don't do that because I don't think my data is worth the recurring cost of that, but its an option.

-------

My point is that when my solution is 200MB/s and on the order of $500 to $1000 for the component ($500 if you build your own NAS, $1000 if you buy premade parts. Assuming 2x 5TB hard drive is just $300 for 5TBs of _mirrored_ storage)...

While your proposed component costs $30 per 0.1TB and read/writes at a lousy 70MB/s... to get the equivalent mirrored setup you need to buy 100 Blu-Rays or roughly $3000 in Blu Ray XLs alone (2 copies of your data across 2-different Blu Rays, for the same redundancy factor as the 2x Hard Drive solution).

So I have to raise my eyebrows a little bit. How are you checking that the data doesn't degrade? Are you manually checking all of those BluRays you've created for reliability? That's a lot of sitting around and inserting / removing drives.

Its literally cheaper to build a 2nd NAS and stick more hard drives into it, and keep that 2nd NAS offsite somewhere.

-------

If you're gonna hold my feet to the fire over this "2-media" thing, then my 2nd media of choice would be Flash storage before Optical. Because SPEED is king. Speed means you can checksum your data and ensure that your backups are still good. I think Flash is a bit expensive compared to HDD, but based off of these BL-XL disks, I'm thinking that Flash is actually cheaper than Blu Ray and something like 10,000% faster. (Tapes would be a more ideal 2nd media... but I'm not "big enough" to make tapes cost-effective).

Yes, checksums and scrubbing. If you want to protect against bitrot (in ANY medium), you MUST double-check your backups over time.

TEST your backups. Any backup strategy that doesn't have a regular testing schedule is null-and-void in my opinion.

I seem to think that HDD, then Flash, and MAYBE Tape (if you're going really, really big) are the mediums of choice of the modern computer user. I'm not really seeing where Optical fits in today's world. Maybe a future Disk format (with maybe TB-level disks) can make Optical a thing again... but 100GB Blu Rays aren't really in the works for the modern user.

70MB/s is slow. And 100GB is too small per storage unit.

Ask HN: How do you handle suspicious logins?
Have an app w/ a decent number of users (250k). I'm working on some login detection logic using IPs, user agents, etc to determine when a log in maybe be suspicious.

If you've taken on this kind of project, would love to discuss what worked/didn't work. Don't want to reinvent the wheel.

My approach will be to track logins by a combination of user agents, locations and timestamps, and then when a new login comes in, come up with a way to make a login threat level based on what's been seen before.

If it's over a certain value, send off an email to the account owner to notify them.
