Is it that good, nowadays? Long, long time ago in university (okay not that long, around 2006), I first discovered NetBeans as superior Eclipse replacement, but about a year later IntelliJ as superior NetBeans replacement. And this was already for relatively simple stuff.
I have a semi-crappy Onkyo CR-N575 bookshelf receiver[1] on my desk because I wanted a small system that could play CDs, radio, Bluetooth, Spotify, etc... (there's not much out there for this anymore).

I've always wondered if buying (or now I'm thinking about making) better speakers would make a noticeable difference in the mediocre sound? I only ever play at pretty low volumes and the receiver itself is no gem.

The manual says RMS output power is 20W + 20W, 1kHz, 10% THD 6 ohms, but then a couple of lines later says THD is 0.05% line in, digital in 1kHz 1W. That's pretty bad, right? If so, then speakers may not be worth upgrading. If they are, how could I tell if these[2] are compatible?

Yes but people are dumb and do stupid things
Components shortage. It's a hit and miss - you created a design, all components are available. You come to order e.g. 100 unit run, turns out the manufacturer already ran out of stock on one crucial component. Ok you can source that component elsewhere (and someone asks 5x mark up), but that manufacturer won't take your stock of components. So you order 100 units anyway, just without that part assembled and you will finish the assembly locally. That complication might have already wiped off any profit you could get on that unit.

Alternative example - one crucial component is out of stock, but manufacturer has a different model of a microcontroller, that is pin compatible but has half of the RAM. You run an analysis and your firmware should run fine, but you may need to do some tweaks here and there. You place an order with an alternative part.

Suddenly you have to support multiple versions of the same product. Then imagine your product team comes up with a new feature that also users ask for. Problem is that it may not work with the revision with half the RAM. Would you offer an update only to a section of customers? Would you replace the boards for free once they become available? Or do you make a completely new version of a product (which is going to piss customers who just bought the "old" version).

Etc. Etc.
These supply chain problems make any planning not possible.
The common "solution" is to only start making a product once you have all parts physically available. But this can be an enormous upfront cost, as you can't order parts as pre-orders for the product come in.
Then let's say you created 1000 units, sold all. In the meantime 5% of crucial components go out of stock and lead time is 52 weeks and growing.
You can probably sustain the company for a year and re-design the product to use different parts, but experience shows that they may get out of stock too.
You are going to have to focus 90% of your time chasing components than developing the product. This is not viable.
Many businesses are closing now because of this.

The 1980 in the title is IMHO way off, as the article itself states:

>Despite the massive effort by the technical field in the early 1980s, it wasn’t until the late 1980s and early 1990s that CAD software became capable enough to be practical in engineering design.

I would put around the late '90's or early 2000's the time where drawing tables actually disappeared and were then fully replaced by CAD and plotters, for a few years in the '90's there were both in use, depending on industry/size of firm, etc., early CAD (and OS running them, and hardware on which they were running) even if functioning, were primitive and slow, and the available "output" devices (pen plotters) were very, very slow.
As a didgeridoo artist (quite niche) playing "organic trance", I rely on others publishing on "my" platform (YT; in case you're interested, channel name's "Wergiftfresch"; meta-observation for yoshua921: HN-users discover everything via HN) to use similar tags as I do and naturally YT will steer me close to them. Note that my niche is so small that I can mostly map the space and the new ones I find are even more niche.

As bandcamp user, the "others who bought this also checked out that" might be helpful, but I seldomly follow them.

As a music consumer (niche metal) I follow the set of bands and naturally uncover close relatives by supporting acts on live shows etc.

Given my time is very limited, I don't feel a big need to discover even more music. Most of my time already is taken by me practicing, recording, mixing and keeping up with publishing next to $DAYJOB and $FAMILY.

My mom, who's a programmer, once worked for Computer Sciences Corporation, which she jokingly referred to as "the whorehouse of the computer industry".

>The company has been accused of breaching human rights by arranging several illegal rendition flights for the CIA between 2003 and 2006, which also has led to criticism of shareholders of the company, including the governments of Norway and Britain.

>The company has engaged in a number of activities that have resulted in legal action against it. These are:

>Its so called WorldBridge Service (Visa Services), which processed and issued millions of visa applications to enter Britain, did not involve British authorities.

>CSC was one of the contractors hired by the Internal Revenue Service to modernize its tax-filing system. They told the IRS it would meet a January 2006 deadline, but failed to do so, leaving the IRS with no system capable of detecting fraud. Its failure to meet the delivery deadline for developing an automated refund fraud detection system cost the IRS between US$200 million and US$300 million.

I would say it's more to keep some weight on the rear wheel and prevent a low-side crash. When the bike is slowing down the weight shifts to the front, whether through friction braking or engine braking. If you are already at the correct speed, lightly accelerating helps bring you through the corner with more even weight on the wheels. Incidentally, race car drivers do the same thing, except when drifting, but you almost never see intentional drifting in road racing.
As far as fraud goes this seems a variety that would have extremely little impact (if any) In terms of lost investor money. They shifted revenue toward the end off the quarter and booked it in the following quarter by delaying delivery.

I’m not saying it was okay, it did present investors with in accurate information, but over a slightly longer period of time it wouldn’t really impact total revenue reported. Basically I’m having a hard time feeling much outrage for this, and the $8 million fine seems an appropriate penalty for a relatively low impact bit of fraud.
"Don't worry, you can manage your wallet completely yourself without any 3rd parties" is in absolutely stark opposition to "adoption will grow and grow." If the only people that use BTC are hobbyists who are willing to go through the trouble to find a way to safely manage their own wallet then BTC will never see widespread use.

Ask HN: What is the coding exercise you use to explore a new language?
What is a good sample program or project to work on to explore the primary aspects of a programming language? Something that can be worked on for a couple hours or days. Something that will give exposure to most of the basics of a particular language. Would love to know how people go about trying out a new language in this way.
people in the tech industry like to overestimate their own skills.

we see the same attitude in software industry - somethin' that has existed since the 60s that software is solved problem. yet everyone has difficulties in shippin' software that actually works whether that's titans like Apple / Microsoft to small mom and pop shops.

Games the difficulty is two-fold. 1: games are an art - and making art to good taste is a complex problem. 2. games are software - thereby suffering from problems encountered by the regular software industry etc lack of labour / resourcing etc
Historically, the Romans used both IIII and IV for 4. The subtraction notation was not standardised until much later. There are plenty of instances of IIII on things like coins from the 17th and 18th centuries (though not that much for dates, for which a shorter notation was preferable), and examples dating back to Ancient Rome.

So, it was at worst old-fashioned but never erroneous.

Did you ever see Idiocracy? It's become hackneyed to say that we're approaching it, but look at the way they handle advertising. Basically the video you watch is just a window surrounded by scrolling advertisement banners. The trend was clear then.

Look at shows from the past, a "1 hour" program used to consist of what, 52 minutes? I know it's crept from 48 minutes to 42 last I checked.

I even remember reading about online advertising going on 20 years ago - the industry was adding animated or flashing ads - anything to get attention (which saw the rise of ad blockers) and the conventional wisdom was that viewers were like cockroaches; you spray them with a new formula, but eventually they become resistant so you've got to try something else.

I mean on some level if you're doing this kind of trading then yeah BTC/ETH/etc trading is similar to trading real currencies.
I think the difference is that the real currencies have a well-known utility at the moment - they're a means of exchange for goods and services. If you're selling EUR to someone, the chances are they're using that EUR to pay for these in the eurozone. If you're buying USD, you're also likely to need that to buy USD-denominated things.

If you're a forex trader, you're trying to make money from people's need to use these currencies.

If you're doing that for crypto, you're doing that but for people who are just also buying and selling crypto - not actual goods or services.

Companies have long done this sort of aspirational marketing. President Cigars (made up) didn't need to be used by the president; the unnamed cowboy, on a poster, smoking your brand of cigarettes conferred some level of vicarious living and cool; etc.

But, which company/companies were first with celeb staff members/owners (ie not just endorsement)?

Planet Hollywood seems like it was an early version of this. Victor Kyam's (sp?) "I like it so much I bought the company" is on similar lines but not quite there. Thoughts?
I use Spotify. Mainly Discover Weekly and playlists, both those that are created by Spotify as ones that are created by others.

I listen to Discover Weekly every week (I think I've missed 1 week in several years). Every time I like a song, want to hear the rest of the album it's on or want to hear more of that artist, I add that song to a big playlist (currently 906 songs) so I can open that artist's page later. On that artist page I often check out the 'appears on' section to check out albums or playlists with similar music. I treat that album/playlist the same as Discover weekly: If I like a song I add it to the big playlist.

I think this works great, I often discover new artists or songs, all more or less in the same (electronicy) genres though. I've also noticed that I can listen to some albums that are different, but it won't get added to my Discover Weekly, which is exactly how I like it. For example: sometimes I like to listen to the Red Hot Chili Peppers for an afternoon, but I don't feel the need to have similar artists added to my mix of songs.

I don't really use the Daily mixes. Every one of those seems to have the same couple of artist and the mix of artists doen't really changes over time.

And sometimes a friend of mine or some family members send me a link to an album or playlist they like.
What?!

I think I've been using MDN for 20 years (I don't remember honestly when it first came to be), but it's first time I hear about it. Banner/link blindness is a hell of a thing! Thanks for letting me know.
This information is wrong the original number is IIII and IV notation was introduced much later.

As proof you can see that in the "portal" of the colosseum in Rome,they are numbered using the IIII notation and the colosseum is from the first century.

Happy to see things like CDK acknowledged as a next step, and being adopted.
Though I've been fighting for that in my SRE teams.

Something that is forgotten with CDK is that you can do anything else with your code. Importantly that might mean inspecting the current AWS region for the number of AZs (a use case we were looking at years ago).

Couple other use cases that had come up in our discussions:

- Reach out to real time config

- Setup prerequisites (VPCs and networking)

- Play tetris while waiting (immediate followed by "ok we're reviewing your infra setup next")
Yes, and also on costs - who hasn't been in a company who tries to either pull cost forwards / backwards across financial years? This is effectively the same, just with revenue.
>, but don't you need a mechanical (non electrical) system for parking breaks?

To some of the replies... I think some clarification needed because the wording caused folks to think of something else such as electronically _controlled_ physical brake pads: https://en.wikipedia.org/wiki/Electronic_parking_brake

I think the gp was trying to ask about feasibility of electric _powered_ magnetic field resistance braking ... similar to an exercise bike ... which would require constant electrical power source. (Similar to : https://www.google.com/search?q=magnetic+resistant+braking+o...)

Magnetic field resistance brakes is practical for regenerative braking but not safe for parking brakes on an incline if the batteries run out of juice. The context is the gp's premise of no physical friction brake components via "(ie. no hydraulics, drums, rotors, or pads)."
That's exactly it. Countersteering is a learned behavior that people aren't aware they do. They will describe it as leaning into the turn or whatever. Then, when they are in an emergency and need a tighter turning radius, they instinctively put in the wrong input and the bike straightens up. Explicitly teaching countersteering helps teach them to respond to emergencies with the correct input.
Heck car salesmen will do it if they plateaued on their bonus comp time and another car will shifted a day or two later to the next month will put them a bit ahead of meeting quotas for that next month. Of course they don’t have to file highly scrutinized financial statements for investors but I still can’t find much outrage for this or fault the SEC for not wasting resources better spent on more harmful fraud cases.
GraalVM is really more like a very specialised JVM that can be used to spit out a native binary for any platform for which there exists a GraalVM version.

But in order to do that, it does some interesting things under the hood, and it doesn't play nicely with reflection by default (amongst other things). For some non-Java JVM languages that's a major problem since their compiler produces JVM byte code that relies heavily on reflection (Groovy is/was a great example of this). I'm unsure how much, if any, reflection Clojure relies on but that would be the most likely reason for it to struggle with GraalVM compatibility.
> An investigation by the agency found that, “beginning in fiscal year 2019, VMware began delaying the delivery of license keys on some sales orders until just after quarter-end so that it could recognize revenue from the corresponding license sales in the following quarter [...] building a buffer in those periods and obscuring the company’s financial performance as its business slowed relative to projections."

This seems very similar to what became known as "fiscal pedaling" in Brazil¹ when the government delayed repayment from Treasury to state-owned bank to hide increase in government expenses. This became the legal argument for the impeachment of the Brazilian president in 2016.

On a vaguely related note, I recall that classic Macintosh, sometime in the 1990s, had (possibly unofficial and/or hackish) operating system support for colour bitmap fonts. But I can't find any reference to this on Wikipedia or Google searches.

I wonder if anyone else remembers this; perhaps there's an opportunity to document/archive something about typography which might otherwise get forgotten.
Another question: what is done with this money?
On the other hand, for example every country's stamps say which country issued the stamps... except the UK. Our stamps just have a silhouette of Liz on them (eventually they'll have a picture of Charlie instead) because that's just how it's always been.

"The Court agreed with the Commission's assessment that iPhone maker Apple (AAPL.O) was not in the same market and therefore could not be a competitive constraint against Android."

This tells a lot about how much our EU lawmakers understand modern technology. While there's nothing wrong with this fine, claiming that Apple isn't in the same market as Android is utter ridiculousness.
Yes to every single one of these notes.
