Same here! We stopped using laptop speakers around 5 or so years ago when we got some good bookshelf speakers[0] instead. We mounted them to the foot of our bed where we use our laptop.

We've since built our own subwoofer and also mounted a bass shaker[1] (transducer) below the bed, which produces actual vibrations in response to low frequencies, by moving a heavy weight instead of a speaker cone.

The tactile stimulation from low frequencies actually significantly helps with immersion, focus, and relaxation, similar to some can easily fall asleep in a running car.

Of course, it also helps when we're just in the mood to transmit high-power bass frequencies straight into our fricken' bones...

Anyway, I think the total for our sound system is below $1k. We never made a parts list for our subwoofer but we estimate the cost to have been around $300–400. The rest of the system consists of the $180 (at the time) bookshelf speakers[0], the $50 (at the time) bass shaker[1], and the $80 (or so) amplifier to drive said shaker[2].

We also use a device called a "line driver"[3] (around $20) to raise the signal level for the input to our bass shaker's amplifier. "Line driver" is indeed the magic search term, and "preamp" will get you garbage (either $2 op-amp boards, or phonographs).

But aside from all the engineering effort that went into it, because it was a really fun hobby project, it's mostly just a mediocre system. We're totally content with that, and proud because it is a great experience for us, and very fun to listen to.

At this point, the only upgrade we would really want would be to find a new living space that can accommodate a rotary woofer[4], which changes the air pressure of the entire room to produce frequencies from around 20Hz down to even 0Hz.

But our current setup is more than enough to thoroughly enjoy and appreciate. <3

Also we store our entire music library in mp3 format >:3

The bit is still a bit, but if the bit is generated at the beginning of a cycle it might have more voltage than at the end of the cycle and this difference could be discernable in the electromagnetic environment around the processor, which might effect the actual movement of the electro-acoustical element after the decoding by the DAC!

It's at least as likely as the coffee scenario.
Isn’t that prevented by making only the depositors whole but wiping out the capital of shareholders?
I think one killer feature would be monitor replacement. For many of us who value screen real-estate and work by ourselves, this would be pretty great. I keep trying to make this work with the Quest 2 but the resolution and lag are just too much to be anything more of an experiment at this point, though I appreciate the continued work on it.

I do really enjoy movies in VR, and sometimes movies with other's in BigScreen. But generally, I am watching TV with other people in the room and suddenly VR makes no sense. Metaverse is interesting in some ways, I like Venues which kind of goes back to movies, but otherwise I only spend a few minutes poking around there. There are some cool games though, but they remind me of phone games that you would just play for a few minutes at a time.

Even Einstein loved to fish!

I made that up, but really. Find your hobbies that allow you to switch your STEM brain off. Then find like minded folks enjoying the same hobby. Fishing is good because it can be solitary up until you're all circling the same lake.

My biggest trick in life has been to just be genuinely interested in what other people do. Most people are interested in the product of what people do, but if you're genuinely curious about their life and what drives their passions and invigorates them, they'll be glad someone finally asked!

Ask for a chef's table alone at your favourite place to eat.

Do pottery even if you've never tried it. Your relationships and your pottery work might not correlate, but you'll find a strength in one or both no doubt!

Good luck
Ten years on and these threads still get hundreds of comments. This must be the world’s biggest salt mine. Ten years ago, millions of nerds suddenly cried out in terror and were suddenly compelled to moan about the loss of their favorite RSS reader for eternity. The volume of the protests are out of alignment with the value that any RSS reader could possibly give, so I assume the nerds are all crying out for the loss of their innocence.
First, use a good adblocker, like Ublock Origin. There's no ads in the actual video the Professor posted.

Secondly, his audience is tabletop card gamers. He does set the scene as to why he's making a video. Most of his audience is not of a technical nature.

I also made a synopsis as a comment so you didn't have to watch the video, since some (including myself!) despise video-only content. But I do follow him on YT. And his problem applies to a LOT of areas on YT, Twitter, Facebook, Reddit, and elsewhere.
Ask HN: FDIC Assessments, how much do banks pay?
Out of curiosity, does anyone know how much banks pay for FDIC insurance? Do they only paid for the insured amount?

Only thing I could find is this: https://www.fdic.gov/deposit/insurance/assessments/proposed.html

But don’t know how to interpret it…

We do not have de-facto open borders, and this is a huge exaggeration. Immigrants are turned away all the time for all manner of arbitrary reasons. Just because there are large numbers of undocumented people in the country doesn't mean that there isn't border enforcement. Border enforcement is just a hard, expensive problem to solve with no clear vision or leadership.
Paraphrasing the complaint doesn't negate its criticisms.
That's totally fair and reasonable. I still will demand that it be able to function in a bang-bang mode using dry contacts, especially from a new entrant to the market, because there's a fair risk that the unit will be in my house longer than your company is in business.
one way of doing that is government maintains a central registry of employment.

Nothing wrong with that. There was nothing wrong with emacs in vim mode — it functioned just fine. I'm familiar with lisp so it wasn't even hard to configure particularly, just not as easy as neovim for my particular use-case.
RealID was supposed to curtail this. They certainly made it hard enough for real citizens to get ID.
Absolutely. I'm not convinced Rivian actually makes it out alive...But I fully expect that at the last dying breaths someone will step in and buy the whole damn thing. Likely Ford. Maybe Apple. Possibly someone in the EV space already but not in trucks/vans like Geely. Rebrand the vans as Volvo Trucks products. If it wasn't for Scout, VW would be a great fit.
Job Scams: How to Spot Them and Protect Yourself
Yeah your mileage will vary greatly depending on your requirements. A couple of years ago I owned a very high-traffic, media-oriented website. Bandwidth costs were my highest cost, not compute or storage. I explored moving to something cloud-based and the cost increase just on bandwidth per GB would have been enough to put me out of business. Yes this was including a paid Cloudflare / CDN account sitting in front of my servers.

I considered a "hybrid" model where I would keep bare metal servers for distributing media but move compute and persistence to "the cloud" but just couldn't really justify it on cost alone. The replication and auto-scaling would have been nice, and were the major selling points, but wasn't a high enough ROI for me.
If you post something on Facebook for "friends", and you have 5,000 friends, then is that really any different from posting publicly? And who counts as "extended family"? Like are third cousins in or out? And if you tag anyone in your post then it's also visible to all of their friends as well.

It's important to protect the private lives of our children. But it's very challenging to draw clear, enforceable lines in criminal laws and social media terms of service.
Heavy trucks are extremely sensitive to fuel costs. They commonly burn more than $300 in diesel in one shift. Add semi chargers at some truck stops on major highways and every truck route that traverses those highways can switch to electric. In-town routes install a charger at the company's own site. The infrastructure isn't a problem.

Personal cars can be charged at home. The main impediment was getting the up-front cost competitive with ICE cars, but the base Model 3 costs less than the average new car.

Tesla sells every vehicle they can produce. So does Rivian. Because electric vehicles are going to replace ICE ones.
Interesting. Marcus for example is explicitly covered by FDIC.

I guess a lot of regular banks have decided that they'll just continue to pay the "dumb money" basically nothing rather than trying to compete with the banks and brokerages paying reasonable interest rates.
> Why did they invent NULL and introduce that third truth value, UNKNOWN?

I fundamentally don't understand how you can have all of the kinds of JOINs SQL has without a NULL.
Fair point, I should do a better job of communicating the unit sizes. Heat pump capacity varies as a function of outdoor temps. A standard unit is rated at 47F but the sizes I'm showing are at 5F (cold climate conditions). Also for this price you get the air quality module which does HEPA, fresh air intake and humidification and a smart thermostat that's designed to fully optimize this heat pump system.
I keep reading lots of horror stories about heat pumps. People are complaining about all of the following:

- Enormous energy bills because under some conditions (cold weather?) heat pumps use a lot more energy than expected.

- Heat pump equipment and radiators taking too much space in small homes.

- Cold homes and/or a requirement to keep windows shut because heat pumps just don't generate enough heat.

- Only suitable for very well insulated homes.

Am I only reading this because people are more willing to speak up when something bad happens to them than when everything works as expected?

I worry that heat pumps are only viable under perfect conditions, installed by exceptionally competent engineers that hardly exist anywhere.

Please tell me it is not so! :)
If that's true, then it sounds like an excellent application for AI. Too bad I can't think of an existing model that you can just throw that problem at. There also seems to be next to no money in it for anyone looking to solve it that way.
Ok, so you don’t buy predictive coding for humans — that helps explain your position.

You also see that some basic production rules (for basic reflexes) could mean the difference between AGI chatGPT and chatGPT today. Because of how it would help chatGPT orient towards the world, I suppose?

I buy that critique because I do view a cybernetic loop as essential to intelligence — there must be some goalstate (however vague) to be achieved successfully.

But, have you seen many claim that chatGPT is AGI? My issue is not with your argument (it’s good!) but the lack of acknowledgment for the reasonability of the position that chatGPT can be called AGI. Most people DO buy predictive coding. And many would view the missing “reflexes” in chatGPT just a matter of good UI/UX (for instance). Yet, I haven’t seen anyone stand up and systematically argue that chatGPT is AGI. (But I’m not on Twitter, so…)
I/O is fast, and efficiency matters for every workload. The sooner your CPU is done running code, the sooner it can go into an energy saving state. Energy saving means a longer battery life on portable computers, and less cost in the server case. Remember that people are running algorithms like this "in the cloud" against millions of concurrent requests. The 40Gbps network card can keep the CPU busy, and users are waiting for you to be done. Writing efficient code to make 1 computer do the work of 2 is just operational cost savings 101.

When I was at Google there was a "rules of thumb" page that described how much of your time X performance was worth. I always looked at that before micro-optimizing, but also always came out ahead. I remember a coworker and I redesigning one of our subsystems late on some Friday evening; the rules of thumb said that the performance improvement we predicted, at our scale, was worth a month of SWE time. We did it in 2 hours. So we came out ahead, and our system worked better. (I joked that my colleague and I would be taking 2 extra weeks of vacation.)

TL;DR performance matters everywhere. The one user using an interactive tool on their workstation will appreciate their day not being wasted by random pauses. The person out and about on their phone will appreciate the additional battery life. And your company's bean counters will be quite happy to hear that your cloud bill or data center expense forecast for next year is down. Finally, it's fun! Truly a win/win. Make it fast!
Audio doesn't use floating-point, it's all fixed-point. So there's no rounding error, only quantization error, and that can be controlled to whatever degree of precision is needed.

1s don't have weight compared to 0s, electrical "high" has mass compared to 0V. Which is "1" and which is "0" (if any) depends on the particular electrical specification of the protocol. E.g. with Ethernet signals are differential, ±3V, with 0V only ever reached momentarily as the + and - switch. There are also lots of cases where the "active" (i.e. "1") is the 0V value, and the "passive" (i.e. 0) is the nonzero voltage. Most reset signals are active-low.
> He sounds genuinely distressed, and I feel for him, but I don't get why it causes him pain in this specific way. It's not your fault!

I’m familiar with this personality and his brand is being distressed about many other things. I think he’s just expressing feelings for his audience or something. He’s also apologized for lots of other things that aren’t his fault- rude magic fans, sexists, racists, people who spend too much money, people who don’t spend enough, etc.

He tends to spend a lot of time apologizing for things that aren’t his fault or that he has no control over. It’s not unique to him, and seems kind of common. I’m not sure what to call these over-empathizers.

Ask HN: Any hobbyists turned professional developers?
So I’m in a little bit of a difficult situation where I have to leave my current with no other one lined up, my current job doesn’t involve technical work in any way so my resume isn’t really suited for any sort of dev job at the moment.

I am still learning programming and I am pretty good at it as is in my own opinion, and I’m confident in my ability to turn ideas into a working products but for a while I’ve been comfortable at my job which kind of led me to become stagnant in-terms of building a portfolio and making myself marketable.

The languages I know well are Python and JavaScript, I also know how to use Linux to a good extent, I’ve played around with cloud computing a little bit—mainly setting up digital ocean instances, but I also dabbled a little bit with Azure and GCP, not much on AWS though. I’ve also been very interested in AI especially after I discovered LangChain a few days ago… the idea of giving GPT and ChatGPT tools (Python Repl, llm-math, document loaders, etc) really peaked my interest.

My goal since I was teenager has been to work in the tech field and be a software developer (I am 21 now), however due to personal issues I dealt with in the last couple of years I continuously put off making a serious commitment to it, but now I am serious about doing it and I figure starting off freelancing would be a solid way to build a resume and demonstrate my abilities to a potential employer.

Ultimately that’s just a guess though since I’ve never tried to do this professionally, which is why I’m here… in your own opinion is it feasible to spend time doing freelancing in order to get professional experience to land a job or should I hold out a little while longer (get a non-tech job) and go to a coding boot camp so I can have certification and try to break into the field that way.

My mind is torn right now trying to think about this, and I honestly need a little help with it. I am open to any and all suggestions here.
...New York-based Signature Bank, which collapsed over the weekend and will be bailed out by the new Bank Term Funding Program (BTFP), the Biden administration announced on Sunday.... [1]

Either Daily Caller is calling it incorrectly or at least one bank is being bailed out as of now. All comes down to the definition of 'bailing out', does it mean that depositors are made whole past the $250K limit, that investors are being made whole, that banks are simply taken over with their losses covered by the government which hopes to recoup the costs when the banks are sold on the market?

Newer dishwashers tend to automatically pop the door ajar to help dry contents. I go with that and tend to leave a clean dishwasher ajar. Also helps isolate stinky food items in a closed washer (I've never understood intentionally piling dirty things on the counter, or worse like my wife does, wet in the sink. I do it temporarily while lazy, but I consider that laziness not staging.)
Very good! Why is this flagged?
I suppose those costs vary depending on where you are located. My understanding is that where I am (Switzerland), the taxation in fact works in your favour and people often take second mortgages for "repairs" when they're close to having paid out their first ones. The downside here is that you have pay 20% of your mortgage in order to get the rest, and when houses typically cost 1M or more, you can imagine it's not easy to actually buy a decent house.

Another thing here is that you can be reasonably confident that the lot you buy will increase in value, so it also biases my point of view.
This sounds like the user directory screw ups that were happening for some people with the seasonal windows 10 updates.

Greg Oden’s Long Walk Home
Ducted systems are horribly inefficient. Why heat/cool the entire house if you're only in one room?

We paid $11k to have a 4-unit 42kbtu mini-split system installed in our condo. We love it. We turn the two units on in the living areas during the day, and just the two units in the bedroom at night. Each unit comes with its own remote and can be programmed individually. No need for an app-enabled/iot multi-zone thermostat. But if you want it, there were addons available to enable it.

The only downside in my mind is limited filtration, since the heat exchangers aren't very big, but we have some nice quiet hepa filters running that keep the air quality quite good.

This does leave CO2 as a potential problem, since its just recirculating inside air, but you'd have the same issue with a ducted system if the intake is inside, which most are.

You can always get an energy-recovering ventilation system, but that does require ducting. Interestingly, electric air mentions bringing fresh outside air in, but doesn't have any details about energy recovery. In fact the details are pretty sparse all around. I couldn't even find dimensions of the units!

All that being said, I hope this succeeds because heat pumps are way better than furnaces, and adding competition to this market will be great.
Nah, that's fine. It's more about specific photos of the kid.

I somewhat agree with this, but I feel like there's some very low-hanging fruit that should be available.

When posting in comments on a video there should be:

- An avatar similarity check. If you have an avatar that is too similar to the channel of the video you're commenting on, your post automatically goes into a moderation queue (or just remove avatars from comments, except from the channel).

- A name similarity check. If you have a name that is too similar to the channel name, your post automatically goes into a moderation queue.

- A huge indication that a comment comes from the channel author. They have some indications of this now, but it should be very prominent, so it's *obvious* when comments don't come from the channel author.

None of these things are going to be trivial to implement for a company like YouTube, but this has been a problem for years at this point. These things could have been done by now.
They can save your files and millions of other files. Then what? Setup a global ad network and use that information to provide targeted ads? My point is these big companies can do a lot more damage. Trust no one online.
I'm also curious why this was flagged
Let's hope not, that would be a disaster. Inflation is far more pernicious than regional bank instability. The fed is acting appropriately in response to a spendthrift Congress, and in the process, stressing the system. There's not a good alternative, especially from the Fed's seat. I'm not trying to make it a political argument, but you're really pointing the finger in the wrong direction. The fed has two mandates when it comes to monetary policy - price and employment stability. That price stability is about market wide inflation, not bank stocks. Banks come and go. If you expect the Fed to prioritize something other than those two mandates, I do believe you're kidding yourself. Rate hikes will continue until the labor market or the inflation data indicate they should stop.
