Funny you should mention Sweetwater because they're also near the head of the table in my mental pantheon of e-commerce greats.

Their website is honestly just above average. Page-load times are fair to middling, the pages are very busy, vendor-supplied copy takes up much of the item page, and categories are difficult, perhaps just an artifact of the industry they're in. But if you dig deep, there is a lot of detail beneath, and the related-items suggestions are usually at least relevant if not spot-on, which is more than I can say for many sites.

But where they shine is the integration of humans into the process.

Back in 2015, I thought I might pick up a digital piano/keyboard sort of thing. I wasn't having a great time making sense of the lingo, so I gave them a call, and within seconds (I think I might've pushed one button in an IVR system), I was talking to real person who knew everything there is to know about keyboards. We talked for probably ten minutes about what I wanted to do, my budget, the ergonomic and acoustic constraints of my workspace, etc. He explained some terms to help me understand how the offerings differed and how those would impact my playing, and ultimately steered me to one of the models that was already on my short-list. We also talked about companion software, but I elected not to take that step at the time.

I went from hesitant to confident, and completed the purchase minutes later. The cool thing is, that confidence followed me through delivery, unpacking, setup, and my first plinking across the octaves -- I never felt alone like I was just gonna have to figure this out for myself, I _knew_ that this was the right instrument for my needs, and set out through basic finger exercises with the determination of one who's divinely inspired.

Then something even cooler happened: A week after delivery, that same sales engineer emailed me, just checking in. To make sure I got everything set up and was comfortable with it, to see if I could use any further help. As it happens, I was fine, but if something along the line had derailed me, this absolutely would've made a difference in getting me back on track. An expert whose entire job is to make sure I have a good experience with their stuff.

Now, I've had other e-commerce sites email me and follow up, sometimes with phone calls, but it's not the same. In some cases it feels like outright harassment (lookin' at you, Global Industrial). Often it's just a ploy for reviews or further business.

With Sweetwater, it's different somehow. Yeah I'm sure their goal is to keep me as a customer so I'll spend more money with them in the future, sure, and I'm fine with that. But they don't lead with the money, they lead with the caring. And that makes all the difference in the world.

With McMaster it's almost precisely the opposite, I've never spoken to a human there and I don't feel like I'm missing anything at all. They're like the supremely efficient robot that just produces the parts I need, immediately and without fail. There's no need for warm-fuzzies in this process, and they seem to understand that as well.
It might not work, and it doesn't have to. McMaster isn't designed to be a highly competitive retail marketplace for the average consumer or the average consumer product.

It's for people building things that already have a good idea of what they need. For the most part, if you need an 18mm long 1/4-20 flange head hex-socket grade-8 bolt in a black oxide finish, you don't care about having a ton of options from different manufacturers, because there should not be a meaningful difference between any of them.
I'm still regularly using an iPad Mini 3 (released in 2014) that's limited to iOS 12. I got the iOS 12 updates that you mentioned. I look at it as it's been eight years and I'm still getting security updates - that's awesome!
One of the first Show HN's i've read where my first thought was "would invest based purely on the single sentence description"

Nice idea. Have fun executing!
Yes it is legal to walk them back if it was a mistake: https://www.wikipedia.org/wiki/Unjust_enrichment
Yet another case of someone being overly confident in an opinion that had no basis in fact.

Imagine if you had looked up to realize the flu hasn't gone to near zero with testing, so why in the world would you think something as unknown as covid would?

Of course that didn't stop many like you from attacking those who tried to call for caution. So while it's "nice" that you eventually changed your mind, consider being more open-minded at the start.

Random advice from the internet.

Investing is based on risk and reward.

Risk is the opposite of protection.

Reward is the result of opportunity.

Opportunities are the result of patience.

If you don't know how to invest, don't invest.

Wait for an opportunity you understand.

Good luck.

Addendum: $50k is a lot of money when it is yours. It is not enough to seriously invest using strategies that work for $50million. A person can live comfortably on very safe 1% returns from a $50million vineyard.
Lwów was probably most Polish city in the region, and generally what's now Western Ukraine had skewed towards polish in cities and ukrainian in rural areas.

In reality, for as late as 1939 the main differences were language and religion, and considerable chunk of rural population considered themselves "locals" not linking with nation-state idea.

This reflects on Commonwealth being rather multi-ethnic and Austro-Hungarian occupation and repression changing little on the areas they took.
Yes this, except it's not even a rebuttle, I'm just genuinely curious where this might be someone's experience because it's very at odds with my own.

I don't honestly care much what people consider the beginning of the week, I try to avoid ambiguity in planning as much as I can anyways for other reasons (this Sunday vs next Sunday for eg.) but I have been tripped up by an unexpected Monday-first calendar in a webapp.
> There are now ways to get rich by doing good work,

That sounds like different test too
My problem with JMeter (and load testing in general) is that all the recommended tools are extremely powerful if you know what you're doing, but provide little guidance if you aren't already an expert. I would love an old school "wizard" app that generates a sensible JMeter config for me.

I've just been using the Apache Benchmark "ab" tool with mostly-default settings for now.
Why shouldn't banks stop funding new fossil fuel projects?
I don't understand. Please explain.
One possible reason is that they can pretend it’s not costing them anything when they report “adjusted” earnings.
Ok, we've belatedly hyphenated. Good point—thanks!
Yeah, I didn't mean actual playing in front of the mirror, I just changed CSS to show like it is in a mirror and found that it's much simpler to follow the fingers pattern.
The circus that is Scrum is probably half of that.
I'm sorry if the response was blunt, nevertheless people really have to take a responsibility for their education and not make inflammatory comments about history of the parts of the world they don't understand or are unwilling to understand.

There is plenty of information regarding history of Lviv and this region in general. It's long and sad, tragic and sometimes beautiful but never simple.

Besides, I found that most people who feign ignorance know history very well and use it for their own agenda. If you know what to search in someone post history it becomes more or less obvious.
The GP wants to donate some software to the community, on the condition that he gets to use any derivative community work on his product. Anybody contributing to the code is clearly informed of that, and decides to do it out willfully.

It's a perfectly reasonable arrangement that adds value to both the community and the GP, and that the GPL "protects against". So, yes, the GP's point stands in that there are uses for licenses other than the GPL. All of the complaints about they only being good for people creating proprietary software are true, they just completely miss the point.
If you get some piece of evidence that you can take to others, then you do in fact learn something about the secret.
The one that I still use is the 3-4-5 rule to ensure a right angle. Still use that one to chalk off sporting fields of play.
Oh, that's disappointing, I was hoping they're entering the MVNO space with a consumer offer. Instead, it's an offer for companies to further spy on their employees :(
I would immediately end a discussion if I were asked that question.

If you want to dismiss me by trying to imply my opinion is driven by a want of something other than accuracy with reality, I can find other people to spend my time with.
> This is a false dichotomy: people can choose to use a framework that handles auth competently, such Django or Rails, no need to roll their own.

If you want a centralized auth provider across different services, then something like Keycloak is indeed a good choice, which is why I mentioned it: https://www.keycloak.org/ Of course, for the actual services, you should go with a standard OIDC/OAuth2 library, or something like that, even a proven JWT library if need be.

Having Django or Rails (or one of the supporting libraries, like Devise) handle auth and permission control for more self-contained applications is also fine.

I'd just like to caution against writing your own badly documented and badly tested framework for auth, along the lines of storing unsalted MD5 password hashes, or even doing certain controls client side (although I haven't seen this personally, I've definitely seen lacking implementations and have heard stories from others in the industry).

> If really everyone would participate, I would give it a try. Would disrupt a lot, but might end up with a honest society.

Do you really want your health insurance company to know that you parked outside a doctor's office, who specializes in skin cancers? You just went for a check-up, but they might want to increase your payments or even cancel your coverage entirely.

Then good luck finding another insurance provider, since they all have that information now.

Or how about all future potential employers knowing that you once visited a union office?

There are so many cases, where people "who have nothing to hide" can't imagine where this could bite them in the future.

You (or your wife/daughter/girlfriend/secretary, etc.) visit a Planned Parenthood? Everyone - including your pastor - now has that info.

You go to a job interview at a competitor? Your boss now knows that.

We have no idea who or what groups who might want to snoop in where we park our cars.

The possibilities for abuse are endless. And as always, we have no way of predicting what use-cases unethical individuals will come up with as these things roll out.
> Also essential reason why Unreal Engine is appealing.

Is that why unreal engine deprecated ray tracing?

You're honestly quiet clueless considering your phrasing.
I bet you haven't worked in a large studio working with unreal engine either.
You have replied to something that I have not said.

I have said that the Taylor series of arbitrary functions have various uses, but there is no benefit in knowing which are the specific Taylor expansions of the trigonometric functions, with the exception of knowing that the first term of the sine and tangent expansions when the argument is in radians is just X.

Solving physics problems using the expansion of an unknown function in the Taylor series has nothing to do with knowing which is the Taylor series of the sine function.
Some takeaways:

"Our method consumes five orders of magnitude less power than previously reported underwater wireless imaging systems"

This is accomplished by harvesting energy from acoustics over time and then triggering a circuit to operate for a brief period before recharging.

The method uses "acoustic backscatter" as a means of telemetry for sending the images

The imaging is done with a HM01B0 from Himax Corporation. They capture 3 monochromatic images using red, green, and blue LEDs. Looking at the produced image given by example, I am not sure how accurate the coloring is, but the shape of the object is well defined on a centimeter scale.

Distance between object and camera is under 3.5 meters. The distance they send the image also appears to be about 3.5 - 4 meters. They mention a feasibility to send images over 40 meters with additional tooling.

Device operates around 3.2 volts (triggered by a "super-capacitor" setup) until it depletes to 1.4 volts.

Memory capacity is 12 kbs, and data transfer rate is capped at 1kbps due to the medium. They send one color at a time using 77-bit packets.
I like to read comments, sometimes I'm reading comments under years long conversations. I like to discover what other people have in mind, some comments are pure quality and it feels like I find little gem. Same reason why I sometimes chose to leave a comment, when I feel I have something interesting to add.
The case of Linux vs *BSD is probably the largest-scale test of efficiency of GPL vs permissive licenses on stuff contributed back. It also looks pretty decisive, too.
Honestly, I had never even considered that and now I feel silly!

We already had the scanner+printer cause my partner works remotely, and I just assumed the cost for toner and A4 was cheaper than thermal label.
It's probably not you, this is not my sphere of expertise. It's totally possible I have either the actual numbers, or the way people talk about the numbers, upside down.
They don't have European operations so I'd imagine it's probably an accelerator in the US like Fermilab or SLAC, but otherwise that would make perfect sense.
The need for anonymity for legal reasons is absolutely not a straw man argument.

I just finished telling a woman how she should be careful on dating apps and always use an anonymous sim card, never give out her real number, or real contacts, to strangers.

But my country is making this impossible now too, and the reason is drug dealers using them for burner phones of course.
It may be an 'intended' (short term) reaction, so Odey et al can profit from shorting the pound in the near term, considering the tight relationship.
cos and sin are the x and y coordinates as you turn around the unit circle in unit speed.
You can remove resolution from the image URLs to get a slightly better version.

However you're right. People hosting this blog clearly are still in the dial-up era.

But then again, archival/historical institutions do this all the time for some reason, that is not providing original scans.
This isn't a UK specific thing. House prices have trended up with affordability in all developed countries as interest rates have moved lower over the last several decades. While it was always reasonable to assume rates could trend higher in years to come, given the deflationary effects of demographics in Western countries, globalisation and automation, I think a lot of people would have believed a path similar to that of Japan was more likely over the coming decades.

Also if had brought my house several decades ago I'm sure I wouldn't be in this position right now. It's lose, lose for my generation. You either rent at stupid prices and own nothing, or you take a gamble and buy a house. I understand why people blame me for this, I just don't know what more I could have done. I didn't buy a house at the limits of my affordability unlike some do (and are basically forced to do). I'm also quite well read on financial markets so for me to make this mistake I think probably says something about how easy such a mistake was to make.
That $11k/year figure is based on 15000 miles/year usage which is close to the average annual mileage per driver in the US.
> Many people find the AGPL to be a nonfree license, myself included.

I don't understand this stance.

From the point of view of the user, the AGPL offers the same freedoms as the regular GPL. If you use the program, you have the right to see and edit its source code, regardless if the program runs on your own computer or on another computer.

How can anybody call this feature "nonfree" is beyond me.
"Universal," as in, "practiced by everyone". (I'm not sure how else one could define that...?)
Because you can do things using bitmasks and single instructions instead of brute forcing using multiple instructions.

Let's say you have a whole heap of 8-bit numbers you want to multiply by 2 and you have a set of 256-bit registers and a nice SIMD multiply command. If you don't have a shuffle you need to assemble your series of 2s for the second operand for each lane before you can even start. This is going to take hundreds of instructions and hundreds of clocks. Shuffle means you load up lane 0 with the "2" and then splat the contents of lane 0 across the other 31 lanes in two instructions and a few clocks using the shuffle unit.

N.B. Shuffle isn't just about splatting. There's a whole heap of different operations it can do that are useful. I just picked a simple example with an obvious massive performance increase for illustrative purposes.
This is not finders keepers.

The article is slightly vague, but my takeaway is that employee got raises. Those numbers went through a bunch of people. The pay went out for months. Then, they realized they miscalculated the raises. “Whoops, we didn’t mean to offer you $150k, but really $140k.”

1. I think they have no chance at getting back the pay from before. This isn’t a banking error, this is regret. As an employee could you be like, “whoops I messed up my budget. I wouldn’t have taken this job at $150k. Please backpay me to bring it up to $180k”.

2. It’s well studied that losses hurt more than gains feel good. People hate having their comp lowered and the stock has already fallen. May be better to leave the comp where it’s at. I mean, it’s not like it was 10x or something. The numbers were reasonable enough for this to be super wide spread and people to not notice for months.
saveall.ai looks really cool.

I wish it were a paid product that I can download my cards from.

I don't want to be in a position where I put in lot of effort to input my cards and then you shut it down.

If the founder is here, do you plan to make this a paid service? If so, when? and will you provide the ability to export my cards? If this is not going to be a paid service do you plan to Open Source it?
They are paid a number of shares and given an estimate of the value of those shares based on some share price. Amazon used an old share price, so the estimate was too high. The only thing being recalculated is the estimate. The number of shares does not change.
You're completely missing the point of my comment. You say "crypto is not as bad as facebook" which is a textbook whataboutism. "crypto" isn't as bad as the Shoah, so what?
I'm familiar with GnuPG and I'm trying to understand how I can actually use age in practice. There doesn't seem to be a good explanation beyond the command line usage. My current understanding based on various pieces across the internet is the following:

1. age has only a single use-case: Encrypting files using public key cryptography or alternatively password-based encryption.

2. It is technically possible to encrypt e-mails with age, but it is not encouraged because the author considers e-mail to be fundamentally broken

3. age should be considered as a part of a wider cryptographic ecosystem. For example, if you need to sign files (or messages), you would reach for a different tool like minisign. I wonder if there is another tool/service that one can use for public key distribution

4. There is currently no tool that tries to combine different modern crypto tools into one big suite. I have no information about what age's author would think about such a tool.

5. age is intended to be minimalistic and therefore less bug-prone/misuse-prone.

6. The author of age talks a lot about forward secrecy. But there is no good explanation on how to manage key pairs over time.

Does that sound right?
Yeah I was just thinking the same thing, zero trust except of course for CloudFlare, you have to trust them implicitly.

It uses mechanical ventilation, and is fine as long as you don't unplug it.
> google for the names of functions

Copilot is a lifesaver here. I almost never have to google function names anymore because it just fills them in for me, while usually generating exactly the code I wanted around it.
That's true, I forgot about Team GB!
They're actually very well sealed: if you turn off the ventilation it gets up to ~2700 PPM CO2: https://www.jefftk.com/p/framery-phone-booth-co2-accumulatio...
Regarding 1, I have seen this happen. I used to work for a govt agency that made a mistake and overpaid a number of employees, who were allowed to keep the extra payment. I'm not saying that's the norm, but it affected a number of people and I have heard of it happening other times as well.
The selling points of these tools is usability and misuse-resistance, not breadth of functionality. OpenSSL broadly fails on both of those metrics (although certainly not on breadth).
What if the authoritarians start lasering these satellites?
I don't think they're referring to scanlines specifically.

Something like the waterfalls in Sonic the Hedgehog come to mind.

https://gamedev.stackexchange.com/questions/167804/did-retro...

There's an image on this page. The waterfalls don't look very good with sharp pixels. A CRT would blur and blend, and you'd have to assume the game designers knew it would happen. It's probably not just a happy accident.
amd seed was intel having to lit give them chip designs... in the 90s.

google was secretly making their own motherboards in ~2004 that were multi proc

"meta" (fucking idiot name) was building a crap ton of secret datacenter hardware and architecture in the 2010s...

and they are part of the secret sauce...

It was by no means uncommon when I was taught in the US but I somehow missed it, instead just internalizing the various relationships directly, and was briefly confused when classmates started talking about SOHCAHTOA working together in college math courses.

What I remember from trig is to draw a unit circle. Most of the rest falls out of that.
> I doubt Big Corporate or VC capital is going to have financed the innovative video game that uses raytracing

Sorry, you don't believe that a AAA game developer is going to take full advantage of the latest high-end GPU capabilities? That's the one thing they have reliably done for the past 25+ years.
To add a data point to this, I recently interviewed at a large tech company. As part of investigating the comp, I ran a linear regression on data from levels and the results indicated that you should deduct a few grand for every year of tenure.
> But I want to understand why they chose this combination?

My guess is scorched earth. BoJo is such a disaster that his own party had to remove him - and even that turned out to be a struggle (getting rid of leaders with challenged hair seems to have been a struggle lately on both sides of the pond). He became that unpopular.

The crew that have replaced him have no chance of winning the next General Election; Truss has even said that she knows she's unpopular, and doesn't care. So by running up the debts, they set a minefield for the next Labour government, which will have no alternative but more austerity. So I guess the Tories are planning to win an election in 7 years time.
Yeah when I saw 2em padding and 1.75 line height in the css I thought "too big". I think 1em padding and 1.5 line-height are a bit better for general defaults.

It often can look better to have more whitespace, but it lowers information density. It depends on the situation.
OTOH two large companies trying to commoditize each other by releasing viable open-source solutions looks like a potential win for the rest of us.
