The remote working place I'm at has a policy of starting with video calls, then voice if video isn't available, down to IM, then email. I'm not an extrovert at all, but I quite like it. We are a relatively small dev team - maybe 5/6 people within a company of 30 or so who we talk to less. It's generally faster to communicate like that, with the benefit that you get to know the people you work with a little.

Just clicking on an individual's face and being able to talk to them without acceptance does feel like a step too far to me though. That said, some years ago now, a colleague and I were saying it might be useful to have a teamspeak-style voice room where anyone in the team could join/leave at will but it meant you could push-to-talk to the room if you wanted to. The idea being that people could share their frustrations easily so the team could help them out rather than have them feeling alone and unable to hit the dial button to ask for help from a specific individual. And you could always leave.

We never got around to setting that up though.
I'd much rather nuclear production operations be handled by larger plants, and storage be handled by the customer. Storage efficiency is the current weak point, not production efficiency.
This policy is odd.

The link could die, the text at the link could change, or the comment at the link could be deleted. Not to mention a comment section full of links is ugly and unreadable.

StackOverflow has the exact opposite approach because they don’t want their site riddled with dead links.

How many people will care enough to send an email to have a comment merger? That really isn’t a solution to whatever “problem” this is.
One of the most interesting articles I ever read was in SciAm, arguing (from a thought experiment, Maxwell's Demon [1]) that information needs some minimum energy to be erased [2] (=reset to a low entropy state). Thus, there's definitely a connection between energy and information. Given the known connection between energy and mass, this would establish the final leg of the triangle.

This raises what I view to be a falsification by counter-example of the original premise. If information (and not _the representation of_ information) has mass, then does a piece of uncompressed information weight the same amount as the compressed information?

Furthermore, information is related to interpretation. A string of bits may be an uncompressed text file, a set of numbers, a compressed image, etc. But it's always the same amount of bits. How can my interpretation of that set of bits affect its mass?

There is a widespread tendency to do things quickly in China and it's not (only) because of absence of checks and balances.

Compared to the UK you notice that when you go to the bank: Clerks work fast, the supermarket: Cashier will scan items faster than you can put them into your bags, local MacDonald's: Your food is ready fast.

It works the other way round: Chinese who visit the UK often comment that everything is slower.
5G is supposed to be the future. But here’s what it’s like today
I'm with you on this. I don't understand the HN mentality of "100% performance at all working hours". Many employers do not need you to be highly performant all the time, but they do need you to be available all the time.

I'm also reading the Phoenix Project [1], and there's a worker Brent who knows every system well and can fix any issue. However, he is supposed to be working on the big company project (think like an ERP system). However, he can't get that work done because everyone and their brother keeps asking for a "quick" five minutes of his time, several times a day. All in all, he is not able to get his assigned tasks done because he's so busy with other interruptions.

If that happens then yes, talk to your direct report and come up with a better solution. But you shouldn't need to block out every interruption ever. There are times when it is warranted.

> And that's just talking about DIGITAL semiconductors where you compile HDL to pretty much generate the transistors from foundry cell libraries. So you have to sign an NDA to get the cell library, but you can at least release your code.

Yes you can release your code, but you can't release your netlist or GDS-II. There's no guarantee that somebody else will be able to take the same HDL and close timing, even with the same foundry libraries (say if they are using a different tool, or different options). You'll also need things like clock-gating cells, memories, IOs (at a minimum) and those are foundry specific, so those would need to be abstracted out in some way.

> For analog chips, you can't do anything. An analog design highly depends on the parameters of the transistors you use, so before you even BEGIN designing, you have to sign an NDA to get the transistor models and you can NEVER open source an analog design.

Now this is where I disagree. Sure you can't open source your analog GDS-II, but maybe that's not the way to go. In my opinion what you want to do is build a foundry independent PDK for a generic 28nm, 40nm or whatever node using PTM models. A well designed analog circuit needs to be relatively independent of specifics, otherwise it's not going to work across all corners (this is more true for modern nodes than the kind of nodes the old textbooks talk about) and it'll be difficult to port to another process. So there's a good chance that analog circuits built for 'generic 28nm' or 'generic 40nm' could be ported to any foundries process (of course the PDK needs to be well designed). Yes you won't be able to push things to the limit as the DRC will be wider, but analog rarely needs to go to the limit. You could probably take the same approach for digital, but that's a lot more open source stuff to build.

Check out OpenRAM and FreePDK45 for academic projects taking this approach. Unfortunately FreePDK45 is only available to those with an academic email (despite being called 'open source'), which makes me very sad.
As someone whose legal arguments have been drastically misunderstood by papers of much higher reputation (looking at you, WaPo), I'm skeptical of the accuracy of the claim.
Basic for a consumer-facing SaaS company, perhaps. I work for a SaaS company, but B2B, and I agree with the other comments - it could almost be a satirical take on a founder's pitch.

Well, what is information? Is it an abstract thing, or does it only exist in terms of the thing which is representing it?

I don't have a clue, I just think it's a relevant question at this point.

We're already here, and have been for ten or fifteen years. The egg-car, min-maxed in the wind tunnel, is ubiquitous.

If you operate an online SaaS business you will know most of these terms (and if you do run such a business and don’t know them it would be highly advisable to learn them). This isn’t an article for the general public but specifically for people that bootstrap (SaaS) businesses, so I think it’s adequate to use the terminology of the field.
>I know it's untenable in practice, but in my perfect imaginary utopia, products on shelves would have minimalistic (and standardized) packaging with no branding crap, and the labeling would be maximized for utility.

It is not so untenable, as proved by RxBar ─ a bootstrapped venture, which sold to Kellogs for $600M a few years ago. The pivot to clean, minimalist design and colors with relevant typography, proved to be a turning point in it's fortunes.

The difference between accidental and essential complexity cannot be underscored enough. Removing accidental complexity, even if it flies in the face of "best practices," can be very powerful and appropriate as long as it's understood where you are intentionally coloring outside the lines and the conditions under which you'll need to revert to best practices for scaling up.

An example: I attended a conference presentation in which the presenter discussed dissecting the implementation of Identity Server into a dozen sub-services with half a dozen backing data stores with Redis caching layers and an Event Source model for propagating inserts and updates of the underlying data. This would be a prime example of accidental complexity gone wild if you built this just to have a multi-container microservice -- unless your single-signon service as a whole needs to support 100MM+ users, in which case this is essential complexity, not accidental.

Reducing accidental complexity but being mindful of how it could become essential complexity under certain conditions in the future is the mark of a wise architect, IMO.
The assumption seems to be that you can transfer mass and energy into information in a way that subtracts from total mass+energy of the system but still shows up when weighed.

To test the hypothesis it's not enough just to weigh the memory. You must ensure that the energy stored in the memory has not been increased, because energy increases the weight of the memory device. (relaxed spring weighs less than tensed spring, storing energy in capacitors increases the weight of the memory).

The paper:
https://aip.scitation.org/doi/10.1063/1.5123794

>Here we formulate a new principle of mass-energy-information equivalence proposing that a bit of information is not just physical, as already demonstrated, but it has a finite and quantifiable mass while it stores information.

(...)

>Assuming that all the missing dark matter is in fact information mass, the initial estimates (to be reported in a different article) indicate that ∼10^93 bits would be sufficient to explain all the missing dark matter in the visible Universe. Remarkably, this number is reasonably close to another estimate of the Universe information bit content of ∼10^87 given by Gough in 2008 via a different approach.12 In fact, one could argue that information is a distinct form of matter, or the 5th state, along the other four observable solid, liquid, gas, and plasma states of matter. It is expected that this work will stimulate further theoretical and experimental research, bringing the scientific community one-step closer to understanding the abstract nature of matter, energy and information in the Universe.

ps. AIP advances is so called scientific mega journal. It has very low selectivity and don't select articles based on importance. They are "peer reviewed" only in the lowest criteria possible.
Inbound -> people coming to the site (instead of salespeople calling them up)

Churn -> people canceling their subscriptions.

Churn Rate -> rate at which they're canceling (ex: 5% a month)

Net Negative Churn Rate -> if the overall dollar amount of people moving from $50/mo plans to $100/mo plans is higher than the dollar amount of people canceling subscriptions.

So while the Churn Rate doesn't change (still 5% a month) the overall monthly revenue is still increasing. This is really hard to do and it's a good indicator that they're making something that people really want and are willing to pay to use.
So basically we have rest mass and relativistic mass. How those two compare? And when we say: energy - mass equivalence we actually mean energy - relativistic mass equivalence?
Instant messaging allows you to set status and busy messages - alas the interface isn't organic as changing it would also disturb your flow.

Also the ability to control actions based upon what status you set is not granular or controllable enough. For example - if busy - only allow some people to send video mail message or IM for later perusal or if some people contact allow them thru if call more than twice, three times.....or if Director - instantly. Equally, to set a response time so if somebody in group A calls, make sure you call them back within an hour, two hours....10 mins etc. Details and control like that.

But back to changing that status, that is the important aspect that needs addressing as currently it in itself distracts from your workflow and having some setup that allows easier access. So if your in say vi, editing a system file - it sets you as busy, if your reading the news - your available, if you're reading email - your semi-busy and some people get thru, some don't.

So a system that detects when your busy, and sets your status would be the biggest improvement in work communications and in effect what we are reproducing is the personal assistant. An intelligence that screens your communications and handles what and when things get to interrupt you.

That is for me the area in most need of some revitalisation.
Well, that certainly undermines the credibility of the Dept. of Justice's previous claims that Assange would receive a fair trial. If Assange doesn't have first amendment rights, what other inalienable, constitutional human rights doesn't he have?

You walk in and your neighbor is working the cash register. Now he tells everyone you know.

All you’ve done is try to obtain privacy, but you can’t walk into the shop and demand that your neighbor shouldn’t be there.

The “expectation of privacy” is really a hope that you’ve marked your identity well enough, which is really the same thing you do online.

Before mindfulness became a category in the app store, I read a Kurt Vonnegut book where he passed on advice given to him by his uncle.

> "But I had a good uncle, my late Uncle Alex. He was my father’s kid brother, a childless graduate of Harvard who was an honest life-insurance salesman in Indianapolis. He was well-read and wise. And his principal complaint about other human beings was that they so seldom noticed it when they were happy. So when we were drinking lemonade under an apple tree in the summer, say, and talking lazily about this and that, almost buzzing like honeybees, Uncle Alex would suddenly interrupt the agreeable blather to exclaim, “If this isn’t nice, I don’t know what is.”

> So I do the same now, and so do my kids and grandkids. And I urge you to please notice when you are happy, and exclaim or murmur or think at some point, 'If this isn’t nice, I don’t know what is."

I think your ability to navigate the ego can be trained.
>There is probably room for specialization in the car industry:

Unless prices for new cars fall off a cliff or renting whatever you want whenever you want becomes stupidly convenient I don't think we'll see any more specialization.

Specialization makes sense when you can have (either own or have easy access to) multiple specialized vehicles. If you're just gonna have easy access to one vehicle per working adult and you're going to shell out $20k+ for it then people are gonna buy a swiss army knife type vehicle (and in this day and age that means something on the hatch/wagon/crossover/suv spectrum).

Nietzsche famously didn't understand one thing: women / mating strategies. The banker's purpose isn't meaningless, it's a means to an end (even if not always consciously pursued that way) and generally works very well.
But that's exactly what it is. When you meet people who may be in your social sphere, inherently these people may have connections to your professional sphere.

Therefore, your status indicators and signals may have an impact on both your personal and professional life.

As a concrete example: I was recently passed over for a promotion, for which I am supremely qualified. The reason being, the person selected plays the status game better. They network better. They have the connections to people who are in places of power.

And I refuse to play the status or any other social games. I believe merit, in and of itself, is the way to achieve. And I am wrong, often.

Anyway, I digress. The reason that it may just feel like the 'make a new friend game' is because you 'fit' already. You may not have to think about the keeping up with the Joneses bit, because you are the Joneses. This way of interacting with new people may just be how you were raised and a part of your culture, so ingrained that it seems just a part of natural society. Do you think that's the case?

I'm not sure what you're referring to by "easy pool of candidates". If you post a job listing online and people apply, is that an easy pool? In that situation, is it the responsibility of the company to find more people to apply if they found someone good who could do the job? It sounds like the argument you're making is referring to more diversity earlier in the process, which makes sense to me.

Assuming there is no racial bias in the selection process, if the pool of people you're choosing from is more diverse and you still end up with a board of white straight males because they were the most qualified in that pool, is that a problem?
I live in Ecuador and I can tell you for sure this is a thing, specially among the wealthy. The benefits they seek are mainly twofold:

- Be able to move freely to the US and around the world.
- Better chance at college admissions and cheaper tuition.

They don't actually plan on living there, is just for convenience and a little bit of snobbery too.

Note this people won't likely take advantage from taxpayers dollars. They pay for medical expenses in full and usually stay in 5 star hotels and make lots of shopping.

That said, this still feels like taking advantage of the system. But a national threat?
This article is shop talk for digital marketing and I see nothing particularly wrong with it. It’s actually a pretty interesting write up from a nuts and bolts perspective.
Ahh that's really interesting, thanks for sharing!
It's just disappointing they're stopping at requiring only a single diverse candidate! If there's no downside to forcing one, why not two? Or just requiring half of the directors be diverse?
