The headline of the referenced NewScientist article has little to do with the paper and the findings. It's just a way to represent music (not even shure if it's new since I've seen such representations in the past). Finding appropriate representations is important to make progress with deep learning and DNNs to understand and generate music; today's approaches based on NLP and word embeddings are not able to properly represent music and its multidimensional complexities. But I don't assume that the model presented in the paper can represent this complexity, or the measured information is the most relevant one.

I'm a full-stack engineer and I've managed to carve out a niche solving problems in software that other programmers have not been able to. I'm looking for focused part-time work of about 3 - 6 months, though no project is too small.

I have extensive experience in manufacturing, specifically in both new-build and third-party IT systems (ERP, FIMS, smaller purpose-built systems) for manufacturing companies. I also have led projects for offering new manufacturing products using existing factory capabilities as a design engineer.

> We need to stop planning project primarily by spreadsheets, where the dominating inputs are costs you can measure easily. There are factors that are not reflected in those calculations that not only affect the quality of the place you're creating, but also the financial burden that the community will have to bear for decades down the line.

Did they just completely assume that this is the case?

There are very talented people who develop modelling for urban planning and infrastructure that do look into these costs and their impacts. But there is no perfect solution, only tradeoffs.
I do think that is fair. The reason that we don't have a visualizer is not that we don't want one, but rather that the value to effort ratio is quite low (and really because the effort is high, not because of low value). I'm sure we'll get there at some point. But at the moment there are more pressing issues for the people who are ok dealing with no visualization (like typing, language server, equations etc...).

Relativity (the fact that the laws of motion are the same in all inertial frames of reference) is itself a crucial part of Newtonian mechanics, except that Einstein's theories of relativity were such a big deal that we now tend to reserve the word "relativity" for his stuff, and call the old thing "Galilean invariance" or similar.
Curiously, general-relativistic effects needed to be accounted for as well.

Quoting Wikipedia, GPS “must account for the gravitational redshift in its timing system, and physicists have analyzed timing data from the GPS to confirm other tests. When the first satellite was launched, some engineers resisted the prediction that a noticeable gravitational time dilation would occur, so the first satellite was launched without the clock adjustment that was later built into subsequent satellites. It showed the predicted shift of 38 microseconds per day. This rate of discrepancy is sufficient to substantially impair function of GPS within hours if not accounted for.”
Personal phone. I have separate computers for work and personal stuff but it's too much of a fuckabout to have more than one phone and watch, so I don't. I regularly use my phone both to test our products and to communicate with coworkers. My phone is mine, my work computer belongs to my employer.

I know some people do the work phone thing and more power to them, but for me, I found it grating and irritating to have to have two handsets on me.

That being said, while my email and Slack access are shared to my personal phone, again, unless something is actively on fire, I don't answer, and, in those rare instances, it's always appreciated by my leadership is a favor I'm doing them, not an expected/demanded part of my job. I don't think that's an unreasonable way to do things.

Ask HN: Ideas on how to get back into programming?
First time posting, long time lurking here :-). I started my carreer many years ago as a programmer and for the past 15 years I've been working almost exclusively in the Security field. I'm starting to think I should be getting back into programming (I never left it to be honest) but all I see is job offers that are too narrow, cloud centric and/or framework/technology specific. It could be I'm probably looking in the wrong places, so here's my question: Does anybody know where to look for "unique" programming jobs, like code-refactoring gigs, technology integration-type of jobs, any type of programming job that doesn't fit the standard requierements? Or any idea on how to proceed forward (well, besides starting a company and trying to get customers)? Thanks for your time!

I'm sorry but I fail to find how this is relevant.

TSR was an old simple trick in achieving a likeliness of non-preemptive multitasking on an operating system that didn't have any multitasking, but only one single active process.

Sidekiq (or Celery or nearly any task runner system) are designed for multitasking operating systems and they all keep the master process running, spawning/forking worker processes (or threads or whatever primitives they use for concurrency) as needed. They don't use CPU interrupts to stay active (IRQs aren't particularly accessible to user space), as most queue systems don't exactly allow it - typically they have a sleep-poll-repeat cycle. Though if the queue system allows it they may sleep waiting for I/O (which, in turn, indeed, could be triggered by an IRQ), but that's the closest resemblance I can find - and it's quite a stretch.
Bastiat's "seen and unseen".
I cannot read the original article (seems to be blocked in the EU? I get access denied), but since this is a general comment:

If the only reason that a job could exist was that people had another job and/or got government subsidy this means the job shouldn't exist - it's not societies' job to support bad companies.

So, if they "just go away" that's okay. Give the people who don't have a job now government support and training to get a better job. At least the companies who tried to get rich by exploiting people stop existing then.
Great question! We hope we have a few good reasons.

This iteration of the project actually came after first working with and then modifying another awesome project called SKiDL (https://github.com/devbisme/skidl).

It's based on Python - but we found that since it's procedural, turing complete and has a rich eco-system - people use to that and there aren't standard composable ways of designing things. Instead of describing your board, you (practically) write a script that generates your board. It entangles your targets with your source-code and can make it difficult to understand the ultimate outcome of what you've written.

Additionally, since it's a potentially very long program, it was hard to write good language support around (a language server for VSCode, a schematic visualiser etc...) that were snappy, responsive and lent to examining modules as well as the whole program.

There's a few operators and first-class language features we wanted as well, like units and tolerances (3.3V +/- 100mV) that just aren't the same when embedded in a string, or class init method.

Normally the light of the big bang is too dim (frequency too low) to be seen, but if you travel really fast the blue shift effect will make it visible, and since this light is uniformly distributed in the sky, it will appear as while light everywhere.
The rate that time is progressing is also going to change this effect a LOT.

Years are passing in seconds in this websites simulation, if you were experiencing it all in "real time" everything would appear pretty much stationary for quite a while.

Even at like 95% the speed of light, you're talking about years of time required to move between stars - nothing will appear to change much day to day until you actually get close to one of them.

Yes, it is like 90% rules of thumb and experience. The reason being simulation is expensive: not just in the software itself, but in the time it takes to learn how to use it, set it up for a particular design, and then run through it and understand if it's actually reflecting reality or not. I've been working on some projects where we really care deeply about noise performance, and even the super-expensive packages which exist (which we can't really afford) don't seem to actually be able to answer the questions we have about the design. Autorouting is similar, autoplacing is basically a disaster here.

I am confident a lot of this is an accessibility and UI issue: if you want to disrupt this you could focus on making simulation and auto-placement tools that are cheap and actually usable, and help inform the rules-of-thumb. But that's a very big investment and mostly orthogonal to making a different way to specify your netlist.

Why is this the better in choice in the long run?

Don’t get me wrong - nothing would make me happier than abundant living wage jobs, but if the demand isn’t there to support them, isn’t poverty level more poverty level jobs in the aggregate a better outcome than a binary outcome?
There is no world in which you get food delivered to your door whenever you want for ~$0 extra while the person delivering it makes $20/hr + benefits, healthcare, vacation. It simply doesn't make mathematical sense. The possibilities are (1) you pay a lot, (2) drivers get paid nothing, (3) the whole thing is subsidized by VCs, or (4) the service doesn't exist at all. With option 3 taken away and the public at large against 1 or 2, it seems like 4 is what we will be left with.

I’d like to see a map of the known universe visualizing atomic density on a log scale.

I’d never seen “a hundred atoms per cubic meter”, but it’s always been my intuition that, without some quite interesting shielding, you couldn’t make it anywhere near the speed of light. And on the other hand, I’ve seen claims that “space is really big” as you mentioned; but that claim has always seemed dubious.
This is great, and I wish it existed for Reddit too (or maybe it does already?). There’s so much good content that’s a bit hard to find now, plus it would be very interesting to see what people were talking about at a specific point in time.

A key idea here is that being poor makes you do worse at high school relative to how well you would do at university. Being stupid probably doesn't. So being more generous to poorer students may result in getting an academically stronger set of students overall, whereas being more generous to stupider students won't.

(I don't know how true this "key idea" actually is. I can imagine ways in which poverty might disadvantage people that would persist through their time at university. But it seems plausible prima facie.)

Please forgive me if you know this already, but just in case: the terms Declarative and Imperative may be useful here.

Declarative: the code describes the desired result.

Imperative: the code describes the operations to take.

Most programming languages are Imperative, but some are Declarative, and some allow a mix of the two. More here: https://www.educative.io/blog/declarative-vs-imperative-prog...

Vtables are pretty solved as well. I do a lot of Windows COM interop. Using the `windows` crate, vtables for COM interfaces are relegated to an implementation detail - instead you simply implement a (typically safe!) trait:

https://microsoft.github.io/windows-docs-rs/doc/windows/Win3...

Which can then be converted to a refcounted smart pointer:

https://microsoft.github.io/windows-docs-rs/doc/windows/Win3...

All driven by win32 sdk parsing and metadata.

But suppose we want to roll our own, because we tend to prefer `winapi` but it lacks definition. That's not too terrible either:

• https://github.com/MaulingMonkey/thindx-xaudio2/blob/master/...

• https://github.com/MaulingMonkey/thindx-xaudio2/blob/master/...

• https://github.com/MaulingMonkey/thindx-xaudio2/blob/master/...

I could more heavily lean on my macros ala `windows`, but I went the route of manual control for better doc comments, more explicit control of thread safety traits to match the existing C++ codebase, etc.

Is there some pointer casting? Yes. Is it annoying or likely to be what breaks? No. What is annoying?

• Stacked borrows and narrowing spatial provenance ( https://github.com/retep998/winapi-rs/issues/1025 - this can be "solved" by sticking to pointers ala `windows`, or by choosing a different provenance model like rustc might be doing?)

• Guarding against panics unwinding over an FFI boundary. This is at least being worked on, but remains unfinished ( https://rust-lang.github.io/rfcs/2945-c-unwind-abi.html )

• Edge case ABI weirdness specific to C++ methods ( https://devblogs.microsoft.com/oldnewthing/20220113-00/?p=10... , https://github.com/retep998/winapi-rs/issues/523 )

> it really should be is 'new rules to limit exploitation of workers reduces exploitation'

The transition is predictably painful. A foreseeable effect of raising labour costs in one part of the market, and an elastic one at that, is lower employment there. Passing a law like this without any support for the workers whose income you're destroying is hard to position as reducing exploitation. If anything, it's exploiting them as symbols, a modern White Man's Burden by Seattle's electeds.
It was over 100 at the peak, I'm not sure how many of us were left last month. You're not far off.
My heart goes out to everyone relying on these delivery jobs to make ends meet, but it is and always has been an unsustainable market and it’s great that this ordinance is revealing this. The delivery companies do the barest minimum to support their drivers and allow anyone with a vehicle and desperate for income to compete for delivery orders. The article alludes to the problem of too many drivers, which is the bigger issue than customers ordering less because of an additional $5 fee. I wouldn’t be surprised if TFA is only politicizing the ordinance to when people have fewer reasons to order delivery while the numbers of people needing to supplement income goes up (cost of living increasing faster than wages).
> Yes, that is very likely true. I would go as far as to say that the "nurture" side of this coin is to a large extent an indirect result of nature as well.

I’m not sure if you’re Asian or have lived in Asia, but…

I have lived and worked in East Asia for 9 years, and I have worked with Asians (both Asian-Americans and Asian immigrants) for decades more, and I will just say that this strikes me as patently untrue.

East Asians (from East Asia) are often better educated as a group, but what they do with that knowledge is often underwhelming.

If a study were to control for things that correlate with intelligence like “was able to work with / game a system that led to immigration”, then I might agree that certain immigrants might have IQ that skews slightly higher. That said, the predictive variable there would not be race, but the ability to understand and work successfully within a complex system.

> which is kinda like "seconds at 1g" if the fuel is a very small fraction of the total mass, which it really won't be in a practical rocket.

I think you mean “a very large fraction of the total mass”… generally the best efficiency comes if your fuel mass fraction is high, as it means there is little overhead of things in your spacecraft of things that are not fuel (the mass of the engine, etc)
