I didn't bother to give sources because everything is pretty trivial to find, but you can Google "tesla 2170 bench test" or "Samsung INR21700-50E bench test" for details of the best cells today, "history of 18650" to see that the format is nearly 30 years old, and "(your favorite 2010 phone) BOM" for some example price data. (as an example: galaxy s4, $5 and 10Wh.) That said, I'm positive there were cheaper batteries at the time, given that cell phone batteries are typically more expensive to make even today and are on the order of 10,000 times smaller than car batteries.

I wish I had some quality further reading to link, but unfortunately I don't. "battery Google" is dominated by 1) overpriced e-stores selling a few cells to vapers, 2) news about handmade cells in a lab reaching some ridiculous performance (yeah, and a handgun kills cancer in a lab), 3) complete unadulterated bullshit from the news/bloggers/social media about battery trends, 4) bullshit corporate PR of companies claiming they're a year away from 900 Wh/kg (anyone working with batteries would give their firstborn child for 900 Wh/kg no joke)... Sadly, it's a mess. The other problem is that an explanation is hard - very hard. It involves manufacturing (and scaling this), thermal properties, funding for research, an analysis of the players in the game, etc etc. I have considered writing one, but it even for me it would be quite a project and even posted here on HN I have a feeling it might fail to get any attention. Nobody wants to read a complex multifaceted failure analysis, everybody wants to read a Bloomberg headline saying we're racing into the future, even if it's total bullshit.

The smell can be rather significant / roughly equivalent to what you get with a dryer with scented sheets at its strongest.

I rather question how “nice” the smell actually is, at best it’s “interesting and not bad” from my experience. I find that sometimes line dryer laundry can pick up a “clumpy”, rougher but yet distinctively line dried texture when compared to the machine or hang dried inside.

For others, when you start helping them with those same issues.
The "but they said this" posts add nothing. The thread is unchanged if they are removed. So I advise, don't post them.

Everyone likes different things.

'1'+1=2 prevents a lot of errors. The languages tries to help you along compared to an harsh error. Maybe you want a harsh error.. halting everything until you declare a new variable with the same type and have to go through a manual conversion. For me let the language handle that. If you are tdding anything unexpected will be caught anyhow if you are worried how things convert.

It's like rust in terms of memory management vs c. It handles it for you..

One reason is that wealthy tech outsiders move to poorer areas and drive up real estate values to the point that only wealthy tech outsiders can afford to buy houses (shutting out many/most of the local residents).
What's actually barbaric is forcing people to move away from their friends and family in their hometowns to come live in San Francisco where there's literally faeces in the streets and a shack costs $1M let alone a livable home when can do the work just fine from their homes. The medium to large 6-figure salaries are a trade off and it's actually fairer to employees to allow them to make the choice themselves.
>There is no them. It's just all us.

In many contexts I would agree, but not here. Say I buy a device, and people discover later that it has surveillance code in it. Why can I not just remove it myself? Who do I need to talk to? The developer of that proprietary code. That's "them."

>That's a sociological problem, you won't solve that with software. Or licences.

>For that you need to get into politics or business.

There are many different angles you can take to approach a problem. One of which is politics, sure: we could outlaw software that surveils its users without consent. That's one approach. But a technical approach is also valid: if all software were free, do you really think users would just accept big tech companies surveilling them? Don't you think we'd have people removing the tracking code, and telling their friends how to do the same?

And by the way, one of the things we see over and over again from the business world is that incentives matter. No, I don't think all companies would have freed their code if the GPL were prevalent, but if it's significantly easier to make their code free than it is to make it proprietary, certainly more of them would. Just look at the state of Linux drivers on x86: how many of them are free these days, and how many of them are proprietary? There are a few high-profile proprietary drivers, but by and large most of them are free. That's meaningful progress! How many of your drivers are free on Windows?

>I haven't see that at all. Open source has never been so popular. Creative common as well.

"Open source" has had a surge in popularity, sure, but its current popularity has more to do with corporate interests than an interest in user freedom - which, of course, was why the term was coined in the first place. As a percentage of that software, the use of copyleft licenses has declined in recent years.

>I'm glad VLC didn't decide that they couldn't read DVD, or OOo read .doc because there were proprietary formats, otherwise they wouldn't have been the popular softwares of today.

Of course supporting existing proprietary formats for the purposes of drawing users to free software is a good thing! I just don't think we should be contributing to the development of more proprietary software. VLC and LibreOffice are both extremely valuable free software projects. (And by the way, they're both copyleft - OpenOffice isn't, but most development has shifted to LibreOffice these days.)

>The open source mouvement is not "free to everyone to use and modify, except the ones that don't contribute and profit from it".

Of course not! Anyone is free to use and modify any free software, including copyleft software. But I think copyleft is a valuable tool to help us build a software commons.

Many modern MMOs are instanced. Thousands in the world, but only a handful in each zone. So that does stretch the definition of massive a bit but it's how they cope.

I think FFXIV has a hard cap of around ~350 per zone, but you get some silly processing outcomes when everyone is in the same area (entities or attacks not being rendered, area of effect attacks randomly only hitting a portion of people within the target zone, etc).
> It just sounds like you don't like the process since you apparently aren't able to express a specific issue with it.

I don't like the process because it has so many issues. It's just hostile in so many ways if you aren't using a VT-100, it's fundamentally flawed because of the assumptions it makes.

> I would certainly be interested to read your specific complaints about the email based process instead of just a dismissive reply.

I'm no longer interested in being specific because it's an evangelical issue, where the other side is just not interested in improving the process no matter how detailed you are, in the end the reply will just be "it's all so perfect, look how easy and nice it is". I also know that being specific with an evangelist will just get me a reply "oh just rent a VPS if your ISP blocks SMTP", I've played this game before.

Just like you just did. If you really can't admit to see a single fault with the system, you are evangelical. That's not necessarily a bad thing, but it doesn't really allow any discussion on the topic.

> Since then, all my jobs for the past 57 years have involved computer programming

As others have pointed out, there are definitely older, working programmers like Margaret Hamilton [0], but who may not have programming as the main part of their job. Would you say programming is the main part of your day as a data scientist (I have no idea, as I've thought DS could encompass a variety of non-programming work)?

A common question that comes up with mid-career programmers is whether they should take the jump into management – how have you dealt with that crossroads throughout your career?

Would be interesting to hear some of the stories.
There are some latency involved when it comes to interplanetary exploration, not to mention communication between planets. That alone gives human exploration a certain advantage in some cases.

I suspect the majority of future exploration will stay robotic though. There are going to be some high-profile missions, but once we start looking more at asteroids and other targets far out in the solar system, then robots will continue to do the bulk of the work.

As far as I am concerned, the major breakthrough here is the reusability that SpaceX is bringing into the table. If we can lower prices of sending stuff to outer space, then we'll be able to do so much more with current space exploration budgets.
You advertise "a powerful pluggable architecture." But Go binary plugins cannot be unloaded. At least not yet. How do you overcome this?
One of the reasons why the quality has gone down drastically is that engineering colleges have started catering to the manpower needs of low-tech, back office and BPO jobs.

Western companies did make a big mistake in not embracing the large talent pool in India early enough for more cutting edge R&D or engineering work. This has worked to harm both sides.

Now it has lost the competitive edge to Huawei which has access to a large and cheap pool of talent. While neither Huawei or Ericsson work on essential/Core R&D in India,

Huawei has a larger presence in India than Ericsson which just runs back office jobs and backend SW development.

India is Ericsson's largest and most promising future market and has been there for 100 years but has always lacked the commitment, thanks to "misplaced nationalism". While I am suspicious of Huawei and China in general, I am happy that Ericsson has competition.

"Linux" does not provide an "official" release for your crappy PC either. If it's x86, it happens to be compatible, but guess what? macOS's x86 as well, hence the whole Hackintosh community.

The difference being, Hackintoshers seem to know they need specifically supported hardware if they want to have a good experience.

> Linux still only has 0.x% market share

Linux will have that marketshare regardless, because 99% of Walmart PCs Karin buys simply come with Windows. If the reverse was true, guess what marketshare Windows would have?

> "Fuck you Nvidia"

It's not like NVIDIA wasn't endlessly approached nicely first, offered assistance by the community etc. So at this point, fuck NVIDIA indeed.

I've been running Linux for close to two decades full time and it has worked sufficiently well for me for all that time, but anyone for who that's not the case, I am willing to help to an extent, provided there was some good faith effort on their part as well, since I am donating my free time.

Now that you mentioned it, I just realized I never have problems related to .pyc files anymore ever since I switched to python 3 a few years ago. I remember I used to have problem with deleting database migration files because python would load the .pyc files of deleted migration scripts unless I also delete the .pyc files (which I often forgot).
I think the flaw in this plan is "your own account". AFAIK, like credit cards, the company maintains that they own the account and can do whatever they want with it, just deigning to give you the right to access it as they see fit.

I am always disappointed that drying racks aren't more common in NA. Even in an apartment, you can set it up overnight and wake up to dry clothing in the morning. Better for the environment and your clothing.
I think this is the currently-inchoate reason people are finding this policy problematic... we know that it's bullshit. You'll be able to move from downtown $EXPENSIVE to rural $CHEAP and the company will aggressively and happily cut your salary and perhaps even "helpfully" backdate it for you, but if you one day announce to the company out of the blue that you want to move the other way for whatever reason, the company will at the very least drag they feet and probably eventually won't approve it.

I've even seen this already happen in real life for distributed companies who already have non-Silicon Valley offices; when someone wants to move to SV and asks for the corresponding fairly massive raise, they've been told "no".

There'll be a honeymoon period where this may be true but this is the inevitable stable point, and we all know it on one level or another.

The only reason this looks even remotely feasible for the companies is the accidental historical fact of them all living in a high-expense area. Once they get more used to a more widespread remote workforce, this policy will only ever work out in the company's favor, never yours. There is NO WAY we're going to have the right to simply announce to our companies one day that of our own free will, we've decided to move to a 30% more expensive place (because why not? they'll pay for it, supposedly) and they'll just give us a 30% (or whatever) raise. Ludicrous nonsense. It's a lie.

If this point isn't a stable point, it'll end up tipping in the other direction... companies pressuring their remote employees to stop living somewhere so expensive and move somewhere cheaper. "Pressuring" here includes things like "when layoffs hit, hit the high-cost-of-living employees first", in addition to direct threats.

Enjoy the remote work honeymoon; it isn't going to last.

Go Micro is a framework/library as opposed to a binary or server. You import the framework in code and it gives you the ability to add additional plugins via new imports. These can then be swapped out via environment variables or flags. We make use of Go interfaces to define the abstractions so all you have to do is create a plugin that implements the interface and that effectively makes it pluggable.

Here's the community led Go Micro plugin effort https://github.com/micro/go-plugins
Sneaky Lenovo uses/used more than 512 bytes for booting, hiding the extra code in a 1MB gap before the first partition. I got caught out when copying partition images and the boot sector over to a bigger drive (I think I was resizing both partitions or something, so didn't just dd the whole drive).

Now, I certainly wouldn't judge someone based on an out of comment snippet from nearly a half century ago, but Knuth has been portraying himself in a less-programmery, more CS-and-teacher-y way for forever, including interviews from last year. And I think he's being honest - that is who he is.

But being a programmer and a computer scientist -are- two very different things. Simply in his daily activities over the last sixty years, Knuth has been writing tens of thousands of pages, doing a lot of math, diving deep into computer science topics. (That is not what I do in my employment as a programmer.) This guy has been sitting behind a keyboard and writing code. (That is what I do.)
Overall, and depending on context, I think this is a moot point. Inaction is as important as action and can be considered a different action in itself. What some call inaction is not necessary a state of being inactive, but simply observing and analyzing the outcome longer, while focusing efforts elsewhere.

Maybe "being on the fence" or staying in a frame of doubt and uncertainty for too long, without developing future steps for a given plan could really be considered disruptive inaction.

It's a chaotic situation. They (the police/nat-guard) likely wanted people inside their homes to prevent further chaos and confrontations. It all becomes more volatile if everyone's on their porch, outraged, as the police "parade" comes through.

I know folks on HN like strict interpretations and reasoning of what's legal or illegal, but all of that gets very blurred during a riot when the situation at any given time is on the verge of getting out of control. It just isn't time for a high-school forensics debate when people are in riot gear.

If a group of highly armed police or military are marching through your street and demanding you go inside--- it's probably better to GO INSIDE at least until they're gone.

I think it's worth trying if you have the availability (somewhere to set up a line or a rack, and low-ish relative humidity helps them dry quickly).

As for whether it's worth changing your habits: that's up to you. Give it a try, see how they smell, consider the lower environmental impact of line drying, consider the lower wear-and-tear on your clothes (tumble drying wears clothes out faster), and make a decision!
