Just adding to what other people have said with some bits from the article and my ramblings:

>energy losses in mechanical gears. These losses can be 1 to 2 percent per stage, and many turbines have three gear stages, explains Powell.

In order to have the generator at the bottom you would need at least 2 things, assuming your generator/gearbox is now going to stand vertically within the tower and take its drive directly in. 1) a differential to change the motion axis, positioned at the top. 2) a shaft that either hangs or is supported at intervals, for the length of the tower.

A couple of issues I can imagine with this,
The diff at the top needs to be of reasonable size. In mining and heavy industrial equipment 10MW gearboxes aren't unheard of, but the article also mentions that the turbine speed is quite slow, so the torque will be extremely high to result in that 10MW.

The 1-2 percent loss of this 'stage' will also necessitate a cooling system at the top separately just for this diff as 2% of 10MW is 200kw of waste energy (heat) that has to go somewhere.

However, an advantage is that you can gear the diff to spin the vertical shaft faster reducing the need for some of the primary gearbox gearing and reducing torque load of the shaft.

The shaft supports will also sap power as you have the weight of the shaft now on one or more bearings. The way I designed this mentally was having the shaft split in to sections, perhaps 5m each so 30 sections, as installing a continuous 150m shaft isn't realistic. Each shaft section with its own bearing for servicing and maintainability. This could be reduced to 1 bearing per 2-3 shafts based on losses vs ease of servicing a 15m section over a 5m section.

Other approaches that don't include a shaft could be considered, hydraulics, belts even.

>InnWind then had to add even more steel because of an unexpected resonance in the structure. This problem resulted from the mass at the top of the tower being so light that when the 41.7-metric-ton blades swung past the tower, they strained the structure at a frequency that was too close to its natural frequency.

Issue 2 raised in the article is that having the mass at the top offsets the weight and harmonics of the blade, moving all that junk to ground level may mean adding ballast weight to counter vibration.

Do we need another app or another disruption to a market without alternatives, driving more disdain for tech and liberalism in America? Not everyone needs to be an entrepreneur. The best that come out of school and get high paying jobs will also continue to get raises and make more money just like everyone else. No industry starts you off at your end game salary at 25. Engineering, business, finance/accoubtibg, law etc will all have people making more and more money throughout their career as they gain experience, specialize, and change positions and ranks.
If you are intentionally treating men and women differently in a way that "probably hindered the careers of some of the women who were my direct and indirect reports" then it's not only un-American but it's also illegal discrimination.

You should be ashamed of yourself.
I am surprised to see nobody has posted a link to Dan Luu's article about benchmarking terminal emulator latency:

https://danluu.com/term-latency/

For me, one of the takeaways from this is that time taken to cat a large file is a poor benchmark of a terminal emulator.

This article also includes a nice demonstration of yet another application of Rust - as an easily reproducible and highly reliable way to load your machine so hard it interferes with your terminal.

This feels like a tacit question.

To answer the way you painted it: it doesn’t have to be either.

The role is eroding because the expectation is, that regardless of gender both partners in a relationship need to be working.

This is to facilitate the rising cost of a raising family in large city environments.
> It's quite funny that they consider this as more trustworthy than conventional "news".

Given the state of conventional news, can you blame them? Foxnews is just a republican party news organization. And everything else ( CNN, MSNBC, WaPo, NYTimes, NPR, etc ) are a democratic party news organization.

It is sad that news has become so political and none of it is reliable. It's just one political side lying, exaggerating, clickbaiting and hating the other political side. It's a political/news war and the first casualty of any war is the truth.

Maybe it was always this way and I was just too young and naive to notice.

> Are they sure? I bet it's just one big echo chamber of people copy/pasting each other, just like every trend on social media (memes, etc).

As long as they don't censor, it won't be an echo chamber. Social media only becomes an echo chamber when the company takes sides. Sadly, google, twitter, reddit, facebook, etc are being forced to take sides with disastrous results. It doesn't help that formerly trusted organizations like the SPLC and ADL have turned extremely biased and unreliable.

The worst part is that news companies are at the forefront of pushing for censoring on the internet. Which creates more echo chambers, which creates more divisions. But I suppose that is good for ratings and that's all that matters to news companies. Not truth, not objectivity. Just ratings.

Given how toxic news media has gotten, it's better than teens stay away from it entirely. How many adults go insane watching CNN, MSNBC or Foxnews? Too many. The news industry has only itself to blame for it's predicament. Nobody trust news for a reason.
This is a $10b contract for the Pentagon, not just generic "government." It is a contract that is guaranteed to involve weapons, war and killing people in numerous ways.

I'm not a parent, but if there's one thing I've for-sure learned about parenthood, it's that it gives you license to passive-aggressively dismiss the perspective of any and all non-parents.
This makes sense. Once you have something with a lot of compute nodes, you have to orchestrate them all somehow. That's the real "operating system" for such systems. Each node just needs a loader and setup program to load work containers. Supercomputers, big cloud data centers, and things built from lots of GPUs tend to be organized like this.

Have things reached the point yet where containers run as Xen guests,
and the real OS is Kubernetes? Then you don't need Linux under your container, and with the right library, you don't need Linux in your container. Less OS state to get screwed up.
I don't know... I traveled around the world for >1.5 year, staying at one country/city for a ~month, and it was the most relaxing time of my life. And I worked full-time, happily remotely, on stuff that was bleeding edge with proper deliveries. It's amazing to work hard on something, then walk out to a completely different culture and plug in part of the brain that is not used at work. That also led to many unexpected creative collaborations as well as starting a company with a person I met at the opposite end of the world.

Hi guys,

just wanted to present my open source project.
The name is just random, so don't ask why :)

On my daily job, I had many situations where I needed such a tool, but couldn't find one (for Linux). I've found a nice utility app for Windows, but for example when connected to a Linux server through ssh, and you want quickly to test some tcp communication with some other server or device, you're stuck with telnet and netcat basically, which just don't offer more advanced options.

So when I saw the Lanterna Java library I knew that was the right tool for the job :)
For all Java haters out there, the plan is to package the application as a "native" one, using the new Java 9 jlink tool, so that you don't have to depend on the JRE installed on the machine.

I would like to get some feedback on the project, do you see it useful, and which additional features would you like to see in it?
My wife and I take at least one staycation a year just for a change of scenery. We will take an Uber to another part of our metro area, stay at a hotel for two or three days and we won't do anything spectacular. Go out to eat and drink, maybe go to a show or just do nothing.

We don't have a bucket list, no pressure to "do" anything, etc.
Most of the comments seem to divide into two categories: those who have experienced this failure mode, and those attacking the author.

As someone who has learned not to do this, here is what the author is saying. You subconsciously care about yourself more than the person you're talking to. When you want something from them, that's a bad idea.

Those two sentences, if internalized, will cure you of trying to be clever. There's no room for clever when you have to be effective. At least, not manufactured clever.
Well, there's a big difference between being at home vs somewhere far away on a beautiful beach.
Cloudflare has a file size limit (512MB) and only caches certain file extensions so for things like binary files, installers, and video it will not cache. For the HTML/CSS/JS asset use case it’s perfectly fine though.
Only a stupid and ignorant American Jew can come with the term "compounding quandary that is Zionism", so out of touch with the fact that for 8 million people in Israel it is just a place where they were born, live in, speak their language, preserve their culture and will probably preserve their identity unlike secular Jews in America who just merge into the general population.

If she had any clue and not just embarrassingly exoticise the mountain Jews of the Kavkaz region like many Ashkenazi American Jews who are completely detached from the other half non Ashkenazi Jewish diaspora, she would know that most of those "mountain Jews" already immigrated to Israel and were involved in the forming of the Jewish defence forces in the early days of the 20th century long before Israel was even formed. She will also know know that in this "compounding quandary" kavkazians are just part of society and nothing to drool over as if they are some lost tribe in the jungle.

The only "compounding quandary" is herself and people like her who live in some academic bubble and have no clue of the reality around them, not because they don't see it but because they can't sense it.

“Debug” and “Release” only pertains to Windows. You are always supposed to build with -g on UNIX and UNIX like operating systems because besides a few miliseconds of startup time, including the source code into the binary doesn’t affect anything but file size. The runtime linker skips those sections and links only code and data into memory, but the source code is there if you load it into the debugger. Kernel engineers taught me this.
Wow this is neat — I’m gonna try this out. Does it really work?
It might be, but if AMD/TSMC start cranking out their 7nm stuff next year, I've read that marketing can't bridge that gap: the 7nm people will have the leading processing technology in the world, and Intel will be trailing for the first time in a long, long time.

But who can predict what will happen...
To hijack this thread a different direction for a moment, is this type of change one that would be allowed to occur in 1.x? How is it determined what changes are suitable for 1.x and what will wait for 2.0, once 1.0 is released?

I never understood the concept of staying in a hotel in the same town. I travel a lot on business and to me, Hotels are not relaxing as much as my own house.

Relaxing vacation for me is to go to a remote place away from your own town, get a cabin and totally unwind. I never understood staycations especially hotel-staycations.
It works at least for nvm (caveat: Installed from nvm directly, not homebrew), and my company's ssh setup script, which are the two reasons I've had cause to use it.
I feel like collectively the tech industry has forgotten what an OS is. We’re so used to Linux bring batteries included now that we assume we can supplant it.

Linux itself is not going away simply because replacing all those device drivers and ABIs is going to be incredibly difficult. Now, if you’re suggesting something new will sit atop Linux as the user land acting as a sandwich-filling between the Linux kernel and a multitude of userlands spanning many systems- I might agree.

I fiddle in this area as a hobby project. One thing I never understand when I read announcements like this is why the graphics performance affects the throughput. Like in a video game, the world moves at the same rate regardless of the frame rate, so why are the two related here?

In some of my experimental terminal emulators I've decoupled these and it's not so hard -- there's a piece that processes command output as fast as it can, and then there's another piece that updates the screen as fast as it can, and as long as those two pieces are decoupled then even if your graphics hardware is 5fps it's still fast to cat a file.
The article is the source.

I hate it when people do this. Take links from articles and cry about being the source.

Sorry, since you didn't bother to actually mention who you were talking about I just assumed it was the first person Google returned results for. My mistake.

Room for ambiguity still implies that it's as reasonable to interpret Roseanne's tweet as a racist joke as not.

In the context of the US and "the way things used to be", if would have to be the wife. Btw, it doesn't really matter which one it is -- the point was that it's asymmetrical.

> The role is eroding because the expectation is, that regardless of gender both partners in a relationship need to be working.

Why would both partners working be a problem in the first place? What about socialized (gasp!) child care?

Obviously, you'll want both parents to be spending as much time as possible with their children, but the underlying problem here seems to be... money. If there were less pressure to earn then maybe both parents could change to a 3-4 days work-week, etc. etc.

(EDIT: I'll actually add a counter-point to my own assertion here. It may not actually be the case that spending more time with one's children is always better. There may be a Goldilocks zone.)

> This is to facilitate the rising cost of a raising family in large city environments.

I think I understand the symptom. Cost means money.

Obviously, things will have to change on a massive scale for "my" conception of the future to be feasible everywhere, but I still understand what this has to do with meaning (as your original blog post was about).
I'm gonna go listen to Cat's in the Cradle and stare at the wall for a bit.
I feel like you are really stretching here. You took a bunch of words out of context so you could parse them.

"Minimal version selection is an "exact" solution, in contrast to the traditional one. "

It's not an exact solution to SAT, it's an exact solution to a simpler problem than SAT (2-SAT). A problem that admits linear time solutions, even.

That is in fact, what a lot of approximations actually are - reduction of the problem to a simpler problem + exact solving of the simpler problem.

Some are heuristic non-optimal solvers of course, but some are not.

Certainly you realize the complexity and other differences between "an exact solver for SAT" and "an approximation of a SAT problem as a 2-SAT problem + an exact solver for 2-SAT"

I can write a linear time 2-SAT solver in about 100 lines of code and prove it's correctness. It's even a nice, standard, strongly connected component based solver.

Here's a random one:
https://github.com/kartikkukreja/blog-codes/blob/master/src/...

So if i have an SCC finder implemented somewhere, it's like 20 lines of code.

Past this, your argument about "taking the user's time" is so general you could apply it to literally any problem in any domain. You can just plug in whatever domain you like and whatever solution you happen to like into this argument.

Here it's backed by no data - you have surfaced zero evidence of your premise - "that it is taking user time". This entire thread in fact has exactly no evidence that it's taking any appreciable amount of user time, so it definitely fails as an argument.

(in fact, the only evidence presented in this thread is that the algorithm simply works on existing packages)

If you actually have such evidence, great, i'm 100% sure that go folks would love to see it!

Because right now the main time spend, in fact, seems to be people arguing in threads like these.

This reminds me of Daniel Kahneman's notion of "experiencing self" vs. "remembering self" (the story-telling self). Here's a story he shares in one of his talks[1] about how the "remembering self" dictates what a person gets to keep as a memory:

Now, I'd like to start with an example of somebody who had a question-and-answer session after one of my lectures reported a story, and that was a story -- He said he'd been listening to a symphony, and it was absolutely glorious music and at the very end of the recording, there was a dreadful screeching sound. And then he added, really quite emotionally, it ruined the whole experience. But it hadn't. What it had ruined were the memories of the experience. He had had the experience. He had had 20 minutes of glorious music. They counted for nothing because he was left with a memory; the memory was ruined, and the memory was all that he had gotten to keep.

And here's [2] another reference -- "Memory Vs. Experience: Happiness is Relative".
