why would you even want something with no screen? I find there are many generic, chinese sansaclip clones out there. All of them use virtually identical software, and they really do quite a good job. Bluetooth, mp3/mp4, colour screens even text files. They are not at all expensive and come with micro sd slots and good battery, so they are really quite complete. I'm not majorly into sound quality, but they seem ok to me. And if you like this stuff, you can even download rockbox, which is literally a whole box of tricks.(edit: as far as putting music on it,
it's basically just plug and play. Also they are surpisingly waterproof)

So my answer to you is to go after one of those cheap chinese things. I would choose one even over a sandisk purely based on how much better they feel. I can't find my precise version at this moment, but i think they are basically all the same. If you are scared to listen to me, go for a small sandisk with an sd slot.

My question is though, is there any true replacement for the Nano 7? I'm talking in terms of it's form factor and screen/general quality.
A Biblical Mystery and a Reporting Odyssey
A lot of people think that because China is bringing online record amounts of wind, hydro, solar, and nuclear power, they must be moving away from coal. But that's not the case at all.

China is very interested in mass producing solar cells, wind turbines and other tradeables for the export market, as well as using them internally. They need electricity from whatever source they can get it. Black coal, brown coal, it doesn't matter, it all goes into the furnace to fuel an energy hungry nation with few petroleum and natural gas reserves. It is a very rational energy policy that puts the strategic needs of China front and center.

That article doesn't link to the study and leaves out major questions about the methodology:

1. How did they decide that the benefits would continue over the course of 4 years?

2. How did they determine what "time lost" was? I imagine it's greater than just extra time waiting at the station. People probably also got lost trying to find a new way around, and were late to things important to them. Unexpectedly being late to a job interview is a very different kind of time lost than saving 3 minutes on your regular daily commute.

50 here and I just read Concurrency in Go this past weekend and absorbed everything faster than I could have in my 20s. I think it is more that the vast majority of people stop using their brains much past the age of 30. (hell, even 25). I'd like to see a software engineering specific version of these studies.

The only thing I lack these days is an intense desire to constantly code - I find there are all kinds of interesting aspects to the creation of software beyond hammering out code.
How do you specifically know them?
Yep, sounds like a classic case of an ERP or order management system throwing documents over the wall because "well all the data's there, so the warehouse can figure it out". And as for "who got paid", probably some COBOL programmer who retired decades ago and is now living the dream entirely offline in a beach house in Costa Rica.

Which goes to show that the warehouses themselves are only part of the battle. Just as critical is the whole org holistically taking downstream impacts into account. It's why I make it a point to be on the warehouse floor, doing the ground floor work firsthand, talking to warehouse workers, understanding and observing for myself where the bottlenecks are. That's the only way to really know you're actually helping.

Progress in neural networks for EEG signal recognition in 2021
In recent years, neural networks showed unprecedented growth that ultimately influenced dozens of different industries, including signal processing for the electroencephalography (EEG) process. Electroencephalography, although it appeared in the first half of the 20th century, was not changed the physical principles of work to this day. But signal processing technology made significant progress in this area through the use of neural networks. But many different models of neural networks complicate the process of understanding the real situation in this area. This manuscript summarizes the current state of knowledge on this topic, summarizes and describes the most significant achievements in various fields of application of neural networks for processing EEG signals. We discussed in detail the results presented in recent research papers for various fields in which EEG signals have been involved. We also examined in detail the process of extracting features from EEG signals using neural networks. In conclusion, we have provided recommendations for the correct demonstration of research results in manuscripts on the subject of neural networks and EEG.

NBN Co. in Australia built our FTTN “National Broadband Network” by employing their own people. I’m pretty sure it’s majority government owned and run, if not wholly.

Everyone complains about NBN Co. and how slow they were but honestly they did a really good job. I think the complaints were amplified by journalists, looking for angry clicks.

(An amazing thing NBN Co. also did IMO was install pull-cables in every conduit, so future upgrades are significantly cheaper.)

It's been a decade or so since I paid attention to Engenius, but I don't think it's right to describe them as a Ubiquiti clone. Engenius for a little while was the vendor of choice for people trying to build out consumer mesh networks. Ubiquiti may have existed then too, but didn't become the more popular choice until a little later.

Back then, Engenius had a lot of nice features and solid products, but their radios had some issues. I think we had to replace about 60% of the Engenius devices we deployed over a five year period. We never had to replace any of the Ubiquitis.

I wouldn't buy Ubiquiti now though.
Better to hammer then coast imo. You build up knowledge that lets you coast later, and also street cred so your extended team knows you can do a good job. But you just take the foot off the gas and then crank for 2-3 hours at a time and that’s it.
This is true to the extent that I think it is OK to lie to get a job or opportunity if you know you can do it. For example there might be opportunities where if I pretended I had no coding experience it might be better than saying I have.

What? Tide mattered more now because it had a significant impact on getting it out quickly.

Luckily it wasn’t nearly as high when it beached itself - but if it had beached itself on the downslope of the peak tide instead of the upslope it very likely would still be stuck!

Tide when it crashed was not nearly as significant as when it got free.

I'm in my late 20's and I notice my mental energy/sharpness being slightly lower compared to what they were at my peak age of 22. I learned to compensate for this with some behavioral and biochemical kludges, but the reality of the trend is pretty obvious at this point.

Ten years ago I picked up biology and recently added to it ageing research as a hobby, we'll see if it pays off eventually. In mice ... many things one wouldn't believe are possible.

Maybe it's the nature of scientific progress - to provide fantastic life-changing results in rodents, often failing to translate to humans in a clinical setting.
After some unexplainable sustained 100% packet loss (for minutes at a time) I switched from a set of eero routers to ubiquiti gear a few years ago and it's been a great experience so far. A single AP-AC-lite covered my entire 2600sqft house from the basement.

Somebody I know has stayed on the eero train (on my recommendation before I gave up on them) and he says the company has prioritized features he doesn't care about and deprioritized features he wished it had.

I hope Ubiquiti doesn't go down this road.
Yes, threads from the Thread extension are real OS threads, which have a Tcl interp in them. Since they are separate interpreters then there's no impact from any kind of "per-interpreter lock".

Passing messages between Threads can be done asynchronously which does not block either thread.

Example Tcl program with threads

package require Thread
set tid [thread::create]
thread::send -async $tid {
while true { after 200; puts Jazz }
}
while true { after 100; puts Party }

This creates one thread which is in an infinite loop printing "Jazz" to stdout every 200ms, and the "main" thread which is in an infinite loop printing "Party" to stdout every 100ms.
I've used T-shirt sizes: S, M, L, XL, and that seems to be a good gauge. Anything beyond XL needs to be broken up into multiple stories. This maps to 1, 3, 5, 8, etc or whatever your tool uses. Numbers are easier to sum than sizes, so that is what gets used in management software.

Agile tries to balance feedback to management with the inherent uncertainty in software development. Most managers are happy to hear something like "This is two big things, and 5 little things." Any analysis beyond that is a exercise in futility. They understand a small thing may take a while for a junior engineer but be a footnote in the day of a senior engineer. So time doesn't really make sense. Lines of code and checkins are both arbitrary metrics that don't necessarily reflect the work put in. I have spent days or weeks on issues that resulted in single line changes, and cranked out hundreds of lines of code in an hour. What else can you measure? Turns out there aren't very many good metrics for software engineering or other knowledge work. All you are left is a "feeling" of "effort." This is really a judgement call that you can only make by combining personal and team experience. If you are jumping from contract to contract you likely don't have the time to calibrate to a specific team's feeling.

Any metric is subject to being gamed, at which point its useless. By not saying "X of Y equates to Z story points" you avoiding creating gameable metric. If points are tied to a concrete value, then people will adjust for that value to try to get promotions/raises/notoriety instead of delivering a quality product. Knowing points are arbitrary makes them less appealing to game.

I struggled with the same question early in career. As I've gone through more sprints I have taken the Whose Line is it Anyway's approach that Agile is "[a] show where everything's made up and the points don't matter". Its not completely made up, but your job is develop software, not assign points to stories, so focus on your job and assign points based on what feels right. If you find you are often wrong when assigning points, adjust accordingly.

In the end, points are only really used for a "big picture" for management. They understand an individual story's points isn't exact. But if the team wildly swings on points sprint to sprint, then someone thing up. Either they are not consistently finishing work, not correctly evaluating work, or something else. So think of less an absolute measure, and more of a relative measurement of output sprint to sprint. That is why each team points their own work, and teams shouldn't be compared to each other based only on point value.

This is all predicated on that management understands Agile/Scrum. If a manager is too focused on points, try to direct them back to concrete Todo/Done lists, as that is what really matters. Sometimes they will try to manage via points, and this will fail everyone in the long term.

I don’t know if there is a technical reason why EV hasn’t come to RVs, but having worked with some RV makers they are basically tiny luxury product makers compared to one of the biggest industries on the planet so probably like 1% of the R&D goes into RVs per inch compared to cars.

Interior space requirements plus maximum exterior width requirements mean that RVs will be approximately box-shaped.

Box-shaped vehicles are just going to have massive energy demands above 45MPH or so due to physics. On top of this, the engine just doesn't mass that much more (in absolute terms) than a car engine, so the mass savings for an electric motor are not increased that much. All this means an electric RV with any reasonable range is going to be heavy.

Hybrid technology might makes sense though as they already have demand for a large-ish battery, and dynamic braking could really reduce wear on the brakes.
Approximately 10% of the Israeli population identifies as "atheist Jews" (more than that are non-religious, but only a minority of non-religious people embrace the 'atheist' label)

I don't see how the identity of atheist Jews in Israel depends on non-Jewish people celebrating Christian holidays in the US (whether those people identify as atheists or not)
> I think it would be fairly shocking to find that something like dreaming would evolve in two species whose most recent common ancestor didn't dream.

I don't see why.

Our most recent common ancestor with wasps very likely had neither eyes nor legs, but we and wasps both have both of those. Perhaps it's more obvious why eyes and legs are of use to terrestrial animals who hunt by sight, than it is why dreams are of use to anyone - but why should the null hypothesis not be that a convergently evolved trait is adaptive and thus likely to be conserved?
Wasn't this AMD's strategy? IIRC it works, but it takes years to make the independent businesses viable. Intel's fabs are not likely to be competitive with TSMC at first, and at present intel chip designs are not competitive with ARM/AMD designs. While some of the latter can be attributed to process technology, I wouldn't be convinced that Intel on TSMC
solves their tech problems.

This sounds like a management solution to what is ultimately a technology problem. Is there any reason to think that intel's business conjoined process + tech design strategy is fundamentally non-competitive in 2021? or is it just that they've failed to compete for chip talent compared to Apple, Nvidia, ARM, and TSMC.
At first I thought it was about robots replacing us.
Are you not including the air travel component of the travel (which often results in the passenger choosing to travel much farther than a typical RV trip)?
I worked on the front page at google around 10 years ago. It was all those things you describe back then too. And at least then there were not multiple reviews/meetings or lawyers involved in releasing something like this. If it's still the same then this probably started as a lunch time conversation and was implemented before lunch the next day.
Understand where author is coming from - but doesn't squash-n-merge (newish github feature) solve the issue of needing to rebase and the issue of having too many merge commits?

Squash-n-merge has nice property of removing unnecessary local information that probably doesn't matter at a meta level (commits are nice when reviewing PR, doesn't matter much later)
Unfortunately CCP would probably destroy evidence and censor information either way. They are so damn consistent I don't think this behaviour shows what really happened.

> Integrating D3 with React is a real pain, because you essentially have a split brain problem where both D3 and React control the DOM.

I agree with you here but

> there is also huge performance benefits in letting only React control the DOM.

Compared to using d3 to operate on the DOM directly?[0] Do you have any benchmarks to back that up? Because in my experience, d3 is incredibly fast. Then again, maybe we're thinking about different applications? (Most of my experience is with animating stuff with d3.)

[0]: Whether or not React is used alongside with it should not matter much, I think, as long as one doesn't trigger re-rendering of the React DOM.
Do you do this on a regular basis?
A modest understatement if you will
At a guess, at least two parts apply, though broadly I do think it's a pretty promising option:

1) EV has been very expensive until relatively recently + RVs are a relatively low volume market => slow to re-design all vehicles. Yes, they re-design the stuff on top fairly often, but not AFAIK the chassis itself. I'd definitely be interested if I'm wrong about this though, rapid chassis evolution would probably be interesting to read about.

2) RVs are often used for long-distance and far-from-Civilization™ trips, which very much does not fit well with the (lack of) charging infrastructure. And even when you do go along highways, the charging time (due to higher power use + storage) is going to be substantially longer than on cars, which are already quite lengthy.

re 2: Driving to somewhere with RV hookups would mitigate that a lot, which honestly would cover the vast majority of how many RVers I know use their vehicles. Charging overnight or longer is probably fine... but campgrounds will definitely not like you (and a bunch of other RVs) drawing that much power, they're simply not wired for enormous load. It'll take time for that stuff to be rebuilt.

"The Atlantic" has seriously fallen off over the past few years. I've been a regular subscriber for two decades now. I've have always enjoyed it as a source of articles from a fairly liberal perspective, yet nevertheless prone to serious introspection and regular challenges to that perspective.

In the Age of Trump, however, it really has just descended into blog-caliber clickbait. The effort at introspection and critical thinking skills just isn't there anymore. Today, the publication just feels like a collection of opinion essays aimed at pandering to Twitter culture.

This month's cover story is titled "Private Schools Are Indefensible" (https://www.theatlantic.com/magazine/archive/2021/04/private...). The author starts off recalling anecdotes about her experience, teaching the children of hedge fund managers at an elite private school catering to the ultra-wealthy.

In the old Atlantic, you would skim through this sort of thing, waiting for the "meat" of the article to begin. References to hard data, facts and figures. Comparisons and contrasts between these ultra-wealthy private coastal schools, and the mundane private schools accessible to middle-class families in cities and towns across the nation. Perhaps even some interesting counterpoint, about minority families being more likely to choose charter or private school when having the option.

In today's Atlantic, though, you never get to that "meat". The introductory anecdotes simply ARE the article! The author hated teaching the children of multi-millionaires at her elite private school, and thought the school was terrible and twelve kinds of racist accordingly. There is zero effort to tie her experience at this school into the broad "Private Schools Are Indefensible" title. Because if you're in the in target audience these days, then surely you already feel that way, and simply want some fluffy opinion content to reinforce your feeling. Right?

I've held on longer than I probably should have, but I don't believe that I'll be renewing with my current subscription expires next year. Which is terribly depressing to me.
