I'm not sure I see what's the point of that distinction.

The entropy of a macrostate is a measure of the indetermination about the microstate conditional on the macrostate. If you don't want to call that 'knowledge' the substance of the matter doesn't change.

A macrostate is not an intrinsict property of a physical system. It's related to our description of the system. In general, the same microstate of the system of interest may be compatible with multiple macrostates.

Given the thermodynamical description of some system I can calculate the entropy if T=T_1 and the entropy if T=T_2 without knowing what's the actual temperature specifying the macrostate. But in the first case the calculation is conditional on the hypothetical information T=T_1 and in the second case conditional on T=T_2.
At it's original price, it's quite useful for small projects such as controlling a CNC (laser, 3d printer, router, etc) or a retro game console, etc.

When you scale beyond that, even a cluster of them can't match a really cheap mini desktop computer.

At current prices, you're definitely better off with the mini desktop. I wanted to add a Pi to my other 3d printer recently, and can't find one laying around, so I went to buy a $15 R Pi 0W2... It's $115 on Amazon and sold out everywhere else. For slightly more, I can get a 3 or 4. For slightly more yet, I'm in mini PC territory. The software can run on Linux, but it's designed for a Pi and the instructions say you're on your own. Ugh.
I tried for the sake of work, but a single crunch completely scrapped that and I haven’t had the mental energy to start again.
> the functional members of society should be the ones to pick up the burden

The most recent serious proposal for canceling debt pays for it by adding a 0.5% tax on stock trades[1]. I'm not really convinced that people gambling on the stock market are "functional members of society," and it's certainly not all members of society that gamble on the stock market. If you have enough money to play around with on the stock market, yeah, you can absorb a tiny tax on your gambling for the good of society. Most people won't be affected by the tax[2].

> They have a hunch, pursue it

There's a lot to unpack in just this.

Can we define an algorithm to generate hunches? (mathematical intuition).

Given infinite hunches, can we define an algorithm to order hunches by priority, to search?

That's the kind of question they'll be thinking about using the symbolic logic/classical algorithms in GOFAI approaches.
Exactly. If I had a choice to invest at arms-length at a company who had good underwriting standards but loaned only based on liquid assets and W-2 income or in a company who very carefully underwrote loans by looking in careful detail at every applicants’ unique situation, I’m more inclined to invest in the former.
Ask HN: How to Nuture a Culture of Reading?
Kinda a follow up to a front page post this week about writing patterns for companies. The biggest (and most valid) concern with it was, that patterns of writing is not the problem, but problems with reading the writing is. This resonated pretty deeply with my experiences as well, so I was wondering if anyone has had any success creating rigging that encouraged team members to read what others had written?
I hope so? But that's hard to study, and Givewell (in contrast to other effective altruism organizations) is fairly conservative about making claims and recommendations.

Just to add what others are saying. Phoenicians (and anyone else in antiquity) would never have "trolled" archaeologists, because the concept of archaeology, or preserving the long-forgotten past, was simply not a concept until relatively recently (like, the late 1700's and even then, not picking up steam for a couple of decades).

> General Michael Flynn, who headed the DIA at the time, later recalled that his staff "got enormous pushback" from the Obama White House. "I felt that they did not want to hear the truth," Flynn said.

Surely that had nothing to do with the controversy he later found himself involved in; where the judge tried to continue to prosecute a case after the DoJ gave up on it. Such naked vindictiveness would be fodder for conspiracy theorists...
The problem is that being google a monopoly, people started optimizing websites for the only owner of "search on the internet".

Google is now involved in so much stuff that search seems to not be prominent anymore (when was the last time you see a new big feature in google.com?). And given the fact that being "1st on google" is an outstanding, profitable way to run a website, the uberoptimization is something YOU MUST do.

This way the most optimized website wins, not the best one.
I've done this but got tired of it eventually. I had an 8gb raspberry pi 4. I ran xfce4 under raspbian/raspberry pi OS with lightweight applications - luakit for a browser, claws mail for email, terminal, and a few background processes. I also casted to my TV from Gnomecast and, later, VLC. Coding was all done in micro with a few plugins enabled.

Mostly it worked pretty well, but with too many tabs opened it would start to become cpu bound. Most electron apps were unusable too.

For me it was a process of trying to spend less time online: the idea was I'd alter my behaviour by using a more limited medium. On that count it was a resounding success. I stopped because I missed games, so now I have an Udoo Bolt Gear, which was about £400 and is good enough for what I play without being wastefully over-specced. Same relative minimalism, but just a bit faster with more room to upgrade. I'd recommend trying both.
Bring uninformed and asking questions should be appreciated, not condescended. It's an attitude that I see too much of in our society but hope to see less of here on HN.

This is a topic I'm also ignorant of, and I'm glad to see a discussion spark up.
> The volumes are different because the technology is locked by a company that doesn't innovate nor mass produce their tech.

Citation needed. I'd love to see some evidence backing up your incredibly confident claim.

> Some companies in China, that ignore the patents, manage to produce 20 fps 23" eink screen. Add color to it and it's the perfect screen for a lot of computer work.

I've never heard of that. Please share some evidence for this please. 20 fps electrophoresis? In my opinion, that's physically impossible unless the screen is 0.1mm thick. How did they escape Q = vA ?
Even file picker APIs are severely lacking with regards to any multi-file filetypes, where opening one file means having to subsequently access further additional files, too (but which files exactly cannot necessarily defined in advance because it depends on the contents of the initially opened file).
There are many ways to do this, either fiddly or a little expensive. You can

- use a Dasung screen or Boox Max with your desktop (expensive, plug and play)

- use a hacked-up Linux e-reader (super cheap, fiddly)

- build something with WaveShare kits and an Arduino/Raspberry Pi (moderately expensive and fiddly, but allows for interesting creations)

- use some app (Termux) on an Android E-Reader (Boox, moderately expensive, quite versatile).

The tech is a bit inaccessible, but not as much as it may seem. Just check out: https://hackaday.com/tag/e-ink/
It is better to talk about the lifetime of a car vs the lifetime of your use of a car. An new electric car has better carbon emissions than a new gas car after 13k miles.

Your point of purchasing a "used car" as a better option reduces carbon emissions by removing vehicles from the system.

Don't buy new cars as a Co2 mitigation strategy is unrealistic and against buying electric is just pedantic and your argument is frankly misleading.

Something about that $4 Billion figure seems exaggerated, intangible, or simply an on-paper calculation. Assuming a truck carrying food is 6 hours late, how much spoilage does that actually cause? Would a pileup on an interstate causing an hours long delay likewise have its "impact" calculated to be in the tens of millions?
haha, this explains. somehow the Teams team does not care, or the product/ops team is organized in a rigid way, hard to make some changes even the dev feels the inconvenience.
Oh it's not something new, many larger subreddits require year+ old accounts, so farms have people create accounts for years now, get a little karma, let it sit for awhile then resell it.

Next presidential campaign is going to be brutal to reddit spam/noise filters, I hope they are ready somehow.
"The attack

What’s interesting is that the attack mostly came from data centers. We’re seeing a big move from residential network Internet Service Providers (ISPs) to cloud compute ISPs.

This attack was launched from a botnet of approximately 6,000 unique bots. It originated from 112 countries around the world. Almost 15% of the attack traffic originated from Indonesia, followed by Russia, Brazil, India, Colombia, and the United States."
For the people who answer this, I'd like to know if they booted from an sd-card or ssd-device as well.
I noticed a huge difference in the responsiveness when using my Pi 4 (only via ssh and with a terminal) for some machine learning jobs after I switched to boot from an external SSD.
For Pi4s made in the last couple of years, booting from ssd seems to be a built-in feature, without any need for flashing anything on the device first, which held me back from doing it earlier.
Sort of... I have a bare-bones system which is based on a Pi Zero W (single core) and runs Debian Buster. It has 512Mb memory of which around 60Mb is actually used. Everything is TUI based and I can multitask by starting up Tmux and running (strolling!) my usual apps. I use it mainly as a Lite Laptop and just plug it into the nearest HDMI screen. I use a spare cellphone for Internet and I can also plug a small USB hub into it which gives me expansion options including USB memory stick, Yubikey and ethernet for my home network. There's a lot of great, resource-frugal software out there and it's been great fun to set up.

Edit: the biggest PITA has been Bluetooth. I was occasionally able to connect and pair, but not always. I eventually uninstalled everything --blue-- and hve not regretted it. I now use a cheapo WiFi keyboard to do the initial login.
Yep, am in the newly renovated 500 complex here in RTP. It's quite nice. They completed the reno about the time I started back in late 2019. Only got to experience it for a few months before they sent everyone home for COVID.

To summarize a bit further, the income is not passive at all.
I refinanced with them 2 years ago; they beat my local credit union and several banks at the time. Closing costs were competitive and extremely easy to schedule -- they sent an attorney to my home.
I listen to metal a lot when coding, but I don't have a specific playlist. I either just let Youtube figure out what to play for me based on whatever they've learned about my tastes, or I use Audacious with my local mp3 collection and put it on shuffle mode.

About the best I can come up with by way of specific recommendations are this series of "Heavy Metal Classics" collections where somebody bundled a bunch of songs into a single YT video.

My main system went down, so I have been using a Pi 4 with 8GB of memory for a couple weeks and off and on for a month. My needs are really simple.

My biggest issue is that it locks up a lot with sites with video. Since I use the Pi mostly for work stuff, I can avoid that and do off-time browsing on my phone.

The other issue is the quirks of a new system. Some apps have no ARM option. Some issues require a lot of Googling.

I don't see why you would anyone would go this route intentionally though. It seems like there would be better options for not much more money.

One thing I do like about the Pi, is that it's a lot less bulk compared to my desktop. It seems like the Pi would be great for people concerned about E-waste. It might also be a good option for people who use it as a client to a cloud desktop service. Last I looked, AWS and Azure didn't have ARM versions available though. So, I would have been limited to a web based client. If that hasn't changed, then I imagine it could soon.
Swapping on the SD card is a nightmare. I found out that disabling the swap actually leads to a better experience, even if it means that firefox gets killed from time to time.

Why Optimizing Employee Performance Is the Future of Work
The US federal government is similar. The President makes $400k, cabinet secretaries $225k, and everyone else less than that. There are a very few exceptions—-some doctors for example.
The anti-nuclear movement should be regarded as we regard the anti-vax movement.

They both seem to have a standard of zero risk without comparison to the alternatives. (Yes, there are adverse events with vaccines, and even with the risk of those adverse events, they do far more good than harm).

There is overwhelming evidence for safety, but they keep bringing up theoretical risks and point to events in the past (see issues with rotavirus vaccine) to spread FUD. Thins ends up hurting everyone.
The one issue with decoupling is that while you may then get it to "work," so many of the features you care about, even the heart rate monitoring and 02 monitor, will "work" on your wrist but will really display data in a manner that really assumes you have an iPhone. A lot of the health features will directly guide you to "look at your phone" to actually get a picture of what's going on, rather than allowing it all to be seamlessly browsable on your wrist. IMO, you are better off selling this and buying an alternative that plays nicer with your Android phone... the utility you will get from this without an iPhone will be severely limited and I dare say will very quickly become an annoyance.
As written by others, probably due to eink the company itself.

I love eink. I have several readers, a remarkable which I adore.

I wouldn't mind using a slow-refresh display for coding. The price just makes it impossible. Having color for this task, even if washed out, would be an absolute boon.

As for all eink announcements, they may have the tech, but they might make it so so expensive that nobody is going to translate it into mass production product. Without volume, we'll never get better prices.

Been watching eink for a lifetime now. I read each announcement as a red herring at this point..
Thank you for the opportunity to submit! We need something like this as it's hard to distinguish commercial games and ones that require downloads from those that aren't and don't!

> It is a minefield of subtle gotchas that have very real implications

Perfectly describes my 10+ years with the Node ecosystem. Not that it's a bad thing necessarily. I've made it my niche and the knowledge I've accumulated has made for a great career. But still, I understand the narrative.
Credit on environmental issues? Greenpeace has a very different opinion about it. Japanese are very sketchy about their whale hunting practices.
Don't forget to factor in all the maintenance costs that one doesn't have to worry about when renting.
It is awful, isn't it? I do wonder how many joules we waste on poorly performing web apps that could be made more efficient by applying less engineering rather than more.
Not a "Go guy" but I try to keep up on the news. They've since added generics and cleaned up some of this since 2020 yeah?
That, of course, immediately raises the question of why, then, this was not done.

There is a proximate answer that still does not get us to root causes: An MCAS failure was rated as a Major condition as opposed to Hazardous, in which case the regulations allowed (but did not, of course, require) a single source of input.

This rating was arguably justifiable for the 737 MCAS in its original form, but its power had to be increased significantly after flight testing revealed the original version to be inadequate.

As it happens, the 737 MAX airframe was not the first use of MCAS: the KC-46 also has it. Despite the fact that this system is less powerful than that which was fitted to the initial production 737 MAXs, it uses two AofA sensors. There is clearly a strong and obvious engineering case for doing so, so simply observing that Boeing did not have to do so does not exhaust the questions that should be asked.

I have seen it stated in several places that using two AofA sensors would have required a warning in the case of their being in disagreement, which in turn would require it to be mentioned in the AFM, which might have prompted a reevaluation of the no-training decision, either directly or through a reevaluation of the risk classification. Unless a smoking gun has been found, Boeing can stonewall on whether the training concern suppressed a full and objective evaluation of the risks posed by MCAS (especially after its strengthening), and thereby improperly influenced design decisions (among other issues), but the concern is obvious to everyone except those who want to avoid considering it.

Thanks! I've been at the same company the whole time. I've been looking externally. Im not seeing much that's comparable pay/benefits/etc. I'd probably have to start over if I did switch because Filenet and Neoxam are obscure. Philly region sucks for tech work. I think remote work isn't a great option for me due to distractions.
Why is this toxic rant re-posted again and again and again?

This post is far from a fair evaluation of the strength and weaknesses of Go. Just a long nitpicking of few of Go's peculiarities forgetting the many strengths that Go brings to the table when building and running real world projects.

This is just another unfortunate passive aggressive post from a Rust evangelist bullying other languages.
I like this article, but it assumes everybody is acting in good faith, so there is that meta issue that this article doesn't address. For example, two situations I have personally experienced several times:

The person who did "it" before may not actually be able to "it"; they rode the coat tails of a person who did "it". This "not it" person will often attempt to reframe the problem as one existing in one of the other areas; either as something were they are an "it" person or as "not my problem".

The response to a "things are broken" may not be Leader: “Wait, I didn’t know things were that broken” but may actually be Leader: “Wait, these things aren't broken in any way, don't touch those things.”

This is not actually a criticism of the article, just if you are trying to apply the article as a leader you may have a "not it" situation or, if you are trying to apply the article as the "it" person, the problem may be the leader.
I went to a talk and toured a US national lab working on this. They were using the slower method that this paper mentions. What struck me most about their process was the overall simplicity. One researcher went to goodwill, bought an old sweater, impregnated a sample of the fabric, and started capturing uranium in the span of a few hours.

They walked me through a cost analysis that borrowed methods and tools from commercial oyster farms. Roughly 50ft lines of prepared binding material would be anchored to a weighted line and buoyed with small floats. Long rows would be unspooled of the back of a boat, left to soak for a few weeks, pulled back in, rinsed with a mild acid, only to be put right back out again. Their calculations showed that they would yield yellow cake at 2x the 2018 market rate. This was in non-ideal conditions, namely slow moving colder water. They expected an increased yield from warmer fast moving water.

Last I talked to them, they were working with desalination plants to see if it would be feasible to post filter their brine. Preliminary cost projections indicated that they might be able to hit competitive pricing, and that was 2018 numbers. The market rate has since doubled.
I think the bulk of the inflation we’re seeing is from the pandemic where we shut off production by making everyone stay home but then dramatically increased demand by writing everyone checks.

Politics arises whenever people come together. It's comfortable to think that we can simply encapsulate "politics" as such, as something for the stupid people and we the enlightened rational technical people don't concern ourselves with "politics" but unfortunately one cannot simply wish it out of existence. Politics is just a label attached to human behavior. Put 3 people together and you will have "drama" (politics on the small scale). Better learn how to understand people's motivations and incentives instead of bitterly dismissing confusing human behavior as "politics".
I have been very stoked with color epaper since the mirasol days and alas nothing has materialized yet out to the mainstream. Looking forward to see how this pans out.
So I don’t get screwed when the rates go up. My current rate is 2.75% if I had to renew this year it could almost double. That could easily be $400-500+ a month. When the rates are low nothing can stop me from refinancing like I did a year+ ago from nearly 4%.
