In theory, you achieve high power and long charge-discharge lifetimes with graphene-based supercapacitors

The Graphene Flagship is focused on developing methods for combining few-layer graphene and silicon nanoparticles to obtain high performance silicon-graphene anodes.

These new methods need to be cost- effective, scalable and compatible with commercial battery electrode fabrication methods (current bottlenecks). Progress continues to be made in scaling up capacity and size. Flexible graphene supercapacitors were on display at the recent Mobile World Congress

Great job PagerDuty team! I love your product (except at 3AM). Keep it up.
It is improbable, but there are many reasons why a specific 8700 might outperform a specific 8700k. There is a factor luck of the draw involved in the specific chips they test with.
Maybe you "become a better person" when you post under your real name, but Facebook, which has a real name requirement, is a cesspool, and this community, where most people use pseudonyms, is relatively civil.

You can have an identity and "skin in the game" without using your real name. You can also use your real name and not care/be aware of the consequences of things you say online.
personally, i think anti-moonlighting policies should be illegal.
Just a note these chips don't have hardware mitigations for Spectre and Meltdown. The first Intel and AMD chips that will have had the time for them to be implemented to offset the performance losses will be coming out next year (Ice Lake and Zen 2 respectively). That being said, like Ars mentions in the article, AMD chips are in general hit less by the OS patches than Intel ones.

If I had the choice between a full time position with 3 days free coding prior, or "let's see how the next 1-2 months go" with no free prior coding, I'd chose the latter.
I wonder if having multiple ways you can hire would be beneficial here. Behind Door number 1 is a confirmed job offer after 5 hours of grueling technical interviews. Behind Door number 2 is a 30 day probation offer after an hour long soft skills + tech interview, etc..

Maybe the lesson here is that the "optimal" strategy is to simply not abstract the problem. Its not "a person" you're hiring, its Bob. And Bob is more comfortable doing X or Y or Z, and Bob is best tested for his skills in ABC manner, etc.

They actually went back and corrected some of those subs which were link aggregators essentially. r/gundeals was reinstated and they have a stickied post describing what needed to be done to be brought back to life. The main takeaway is that there is no p2p transactions allowed, only links from stores/manufacturers.
Every time you see a post on the front page you don't like, filter that sub from your front page. So easy. Unfortunate that Reddit limits you to filtering 100 subs from your front page.
Regarding the idea that "human vision is biased to search lateral space over vertical space", what has influenced us to have writing systems that are almost universally horizontal?

I can only think of Japanese that may be written vertically.
That's.. that's not at all true. If it's a news story, then the GDPR isn't applicable.
It's probably not for most people, but this is how I got my job as a C++ programmer in CAD software industry (Computer Aided Design) that lasted over 10 years.
It was a combinatorial sum-of-n problem. Given a sequence of integers, can you produce a target by summing N of the values. He used Excel to put the expected return value in column A, the target in B, and C+ were values. Saved as a CSV which his program ingested. It was neat, actually: the rationale he gave was that it made it easy for anyone to add test cases.

(The candidate was previously in the accounting biz, so his navigation of Excel to do this was wizardlike to produce a few dozen test cases in about a minute.)
I'm sure Elm design considered JS, but I'm also sure that if WebAssembly had been available when Elm was designed, it would still have targeted JS rather than WebAssembly. Same goes for ClojureScript.

WebAssembly is a refinement of asm.js, which started as a mechnism to enable C/C++ code to run in browsers. Other, managed languages aren't forced to go the asm.js route because their semantics aren't tightly married to a byte addressable, untyped program heap.
Just the db limit, but yes increasing to 128 shouldn't be an issue.

Edit: Passwords are stored with bcrypt hash. That's right password limit shouldn't matter.
Was this shitcoin on exchanges aleady? If so, maybe the shitcoin headmaster in this case decided to change his plans from full on exit scam to massive dump and pump.
It's unreal that will people will bitch and moan about having to invest a couple days, maybe even a whole week in cramming/prepping/interviewing, to perform on-demand, one time, for a job that realistically will earn them $100k, $200k, $300k, $400k+ a year. Meanwhile people that work harder than us 5 days a week for the entire duration of their career will make 1/2, 1/4, 1/6th, or less of income, with none of the perks, flexibility, mobility, etc.

I mean good lord. People are asking for an objective/verifiable measure of a skill that's entirely in the domain of your supposed education and/or work experience. How much more straightforward can things get? Would you prefer that it be based on ... who you know in the company? How much you can bullshit your way through a soft skills quiz? How much buddy-buddy rapport you can establish with your interviewer?

These are objective measures on a set of borderline "well known" problems, ... I can't imagine a simpler thing to prepare for. There is no guessing. The amount of hoping someone just "likes" you is at a bare minimum. The impact of resume fluffing is minimized.

I literally can't think of anything more fair or objective.

I can't even fathom people that aren't willing to make these miniscule one-time efforts where there are literally buckets of money waiting on the other side of the gate. Money that most non-tech people will never ever dream of obtaining.

I'll take all my downvotes now, but I'm willing to karmically die on this cross. :P
You could add commenting.
Founder here. To the best of my knowledge, you are correct. ACID is getting thrown around a lot these days, and not being used in its strictest sense.
When I first started using reddit, there were no accounts/logins and no comments! Just vote buttons for each story. Truly "reddit" as in "I read this [and it was interesting so I'm sharing it here]". Slashdot without all of the noise.
I personally know a designer that had an applicant try to pass off _his_ work as her own.
> Apart from getting a candidate to actually pump out some code, even trivially, we don't really have a way to de-facto verify that the person says they can do what they say they can do, short of a personal reference from someone, say, in the company already that knows and has worked with the person in the past.

And it's enough for someone with good social skills to get a great recommendation without skills.
It's literally impossible for moderators to be neutral, for anyone to be neutral. Even judges are well known for leaning to one side or the other.
In my experience, the academic subreddits found in the defaults are pretty civil (i.e. science, philosophy, space, history). But they all have well-defined mission statements and heavy-handed moderation (e.g. no memes or any other kind of offtopic discussion).

That said, starting from zero is still a good idea.
Until everyone does it. I've seen the pre-check line longer than the normal line.
Again -- entirely unrelated. In the reply that was sent to the website owner. They received an explanation.
This is amazing! Is there a roadmap of what is being worked on or is this mainly a dump of their existing codebase?

From looking at the commit history it seems like this is pretty actively developed.
This is bizarre to me - the average comment quality on /r/politics is both more informed and higher level than about 90% of subreddits.

Granted it's center-left most of the time (from a US perspective anyhow - as a European it is at best centrist) but that's more a function of a reaction to the current climate than anything else.

So I guess I'd ask: "what kind of comments are you looking for?" because outside of the science communities you're not going to find better discussion threads.
Comparing porn to white supremacy is just that kind of political view that feels completely alien to me. It was not many years ago that Monty Python poked fun at a whole nations conservative view about nudity and porn, and it seems like globally we have taken a few new step backwards toward the 19th century views about those topics.

The biggest porn section in reddit is currently ranked 61 of all subreddits. Cat picture section is ranked 6 and is 18 million subscriptions vs 1.4 for the porn. Do reddit have some 18 times more sinister business relationship with cat shops, veterinarians, and cat food, or should we just conclude that reddit reader are human with human interests and as that goes most people prefer looking at a cat picture while a smaller minority goes to reddit for a dose of nudity.

Go to http://redditlist.com/all and look at what the people want to consume. Celebrate that science is where it is.
Is it really? I think what he's trying to say is that we should have tools powerful enough to let the Government find/track people efficiently and correctly as long as there is a lawful reason for doing so. Its similar to the weak crypto arguments where Govt. agencies argue they should be able to break crypto protocols via a backdoor when there is a lawful reason to do so.

That being said: the PATRIOT act and NSA's PRISM program have shown just how blatantly the US Govt. can abuse individual privacy and rights so I don't think its a good idea. Weak crypto using backdoors is just a terrible idea period.

I guess what I'm trying to say is that the logic make sense in principle even though in practice it wouldn't work that way.
Do we know where/how Apple uses FoundationDB in production ?

I love seeing the resurgence too. I wish the HN site would give some more love to their RSS options. /rss is OK but I'd like to see a separate feed for everything in /lists and a feed that will allow me to monitor responses to comments, by user or by specific comment, like what /threads?id= shows, so I don't have to constantly rescan that to see if anyone has replied.

The instructions definitely aren't shitty. Pictures-only makes it really simple and the instructions are clear and display exactly which components are required at each step.
It does test for having a wider skill set that just memorising a text book.

Ill give you an example of a task that I got in my 2nd/3rd year of employment.

Came into work and was presented with an exotic (for the time) piece of hardware (A0 digitizer) that cost 3x my salary to be asked to.

1 Connect it up and get it talking to a PDP

2 Research and Write the code to allow the kit to interrupt the os and transfer the data to a second program (this is on RT11 which only allowed 1 process normally).

3 Work how to initialize and calibrate the kit

4 Was asked to go and chat with one of the senior engineers and work out how to use the kit to digitize the results from his experiment to produce a 3d representation of the droplet cloud - z axis was done by using a camera with a very tight focal plane

This is definitely the way to handle reddit. I mostly stick to local sports subreddits and a few general interest subreddits (i.e. not /r/funny, /r/pics, etc) and I think reddit is a great tool.

I think it's the same thing with most social apps though. Small discord servers allow you to build up groups of online friends, but if you just go into the specific game ones you're going to end up with a mix of good and bad.

Overall it's just an issue of popularity bringing out the worst in people.
If we mix blue and yellow together we get green. How about purple and yellow?
If you do, then ask the user.
the /r/apple comments are pretty awful and incredibly overrun by Samsung and Android fans however. The quality of discussion is generally pretty weak.

Good link content however.
That's certainly an option, but choosing which subreddits to replace leadership on is a very tricky task. You can't realistically say all subs and picking and choosing will cause riot if there's any possibility of political reasoning. The way I see it they'd need guidelines that are automatically enforced. Even then though some subreddits work quite well with extremely strict, almost echo chamber, levels of moderation. For example it would really be a shame if askscience or askhistorians were caught up in it even though they're very strict with what they allow.
Enable landscape, please!
I had a pretty well-curated list of subscribed subreddits but reddit decided some of my interests are problematic and I deleted my account. Posting links to licensed firearm dealers legally selling firearms is too taboo for a site that has subreddits organized around linking videos of people dying.
You get banned.
it's heavy enough that most people dont steal it. i leave my motorcycle sitting out too. Sometimes I lock it up though.
One of the most unique blues I've seen is 'Baystate Blue' it's a fountain pen ink [1], cameras and screen doesn't capture how beautiful this ink is. This ink is also highly controversial in fountain pen community because it is accused of destroying fountain pens. (Also you drop it on plastic, and you'd need to use bleach to get it off), but man I love this ink.

Because I fundamentally don't think a random foreign entity should dictate how I manage logs on my personal blog. It's challenging enough to debug issues without having IP issues.

I don't even consider a random IP to be PII.
Are you assuming they would have sought out longer form or higher tier content otherwise?

My dad was extremely happy using Stumbleupon for years. It was about as high-pace low-quality you could get on the internet. I showed him sites like Reddit and elsewhere but he was very content with just Stumbling.

People like to blame FB/Twitter for low quality content without considering the huge market for that stuff. People aren't the ignorant sponges who can be pushed/pulled in whatever direction other people think is better for them, which is how everyone seems to treat the average internet user or voter. Much like trying to blame the whole "obesity crisis" on some evil capitalist food producers, without considering the natural evolution of the workplace, evolving urban environments, technology, chemistry, or just standard irrational human behaviour to be lazy and knowingly make bad choices.

I'm sure quite a few ivory tower intellectuals had their way they'd ban tabloids like National Enquirer and trashy reality TV like Big Brother. But I doubt that would suddenly make these demographics any better informed or better citizens.

We can try to push back against straight up lying, at least when it goes beyond entertainment, but demand will always find supply in the marketplace...
So long as we're just talking about programming stuff, I find Safari Books Online ($400/yr) to be well worth it. When you compare the value to the Angular classes mentioned in the OP at $130/each or $280 for the whole package, I'd think Safari is the obvious choice since it gives you access to so much more. While it's mostly books, there are a lot of video cources too. They have a free trial so you can see what they have first.

Before I subscribed to Safari, I subscribed to Packt Publishing's similar service ($100/yr) at the time. They also have video courses, but mostly books. All of their books are on Safari too. I found this so useful that I "upgraded" to Safari after the first year.

Outside of programming, in the days before MOOCs were popular, I had purchased a lot of The Great Courses classes. They are top notch, and live up to their name. Most of the ones I bought were on art history, general science/astronomy, and history. They are very in depth, usually anywhere from 30-60 hours of lectures, plus reading materials. I know they have a subscription service now, but last I checked the courses that would interest me most were available as part of that. They did (maybe still do) play games with their prices, having them cost $300-$400 regularly, then going on sale for $100 or so every year. You might also look for used copies on Ebay.
No one here has a contract that forbids working for other companies in your own time. I haven't seen that in the DC area.

Maybe that's a Silicon Valley thing?

People might have clauses to prevent people from working on similar work for competitors, sure, but I haven't seen anything that bars working on other kinds of projects outside of work.

I run a forum and I've had to deal with mentally ill individuals, you don't understand frightening that can be.

They have all the time in the world to hack your software, doxx you, create entire blogs to attempt to publicly ruin your reputation, call your family, your employers, etc. You give them a podium to post their views and they will use it. Internet armchair psychologists more toxic than that? You should only hope so.
I don't have a Reddit account but I lurk there regularly, in my experience that only works as long as the subreddits are very niche and not well known. As soon as they get popular since there's effectively no barrier of entry for the general Reddit population you effectively get the same community everywhere.

Normally when people find a forum that interests them (like, say, HN) they need to bother creating an account, often validating an email etc... It only takes two minutes but that's enough friction to weed out the vast majority of the people who just stumble randomly on one of your posts. On Reddit once you have an account you just have to click a button to subscribe to any community you like. It's "eternal september" on steroids. 4chan had "lurk more", Reddit is "repost more".

So your post sounds a bit to me like "Twitter is great if you know the hashtags to follow" and it's probably true but at this point is it really representative of the website? If you need to filter 99% of the content to make it usable, maybe there's a bit of a problem still? I just went to /r/all and had a look at the subreddits available there, I find 16 million accounts subscribed /r/gifs, 3 millions to /r/politics, 17 millions to /r/gaming, 18 millions to /r/pics etc...

So yeah, I'd believe you if you told me that /r/common_lisp, /r/mongolia/ and /r/treepics/ are amazing communities but I don't think it's enough to redeem Reddit as a whole.
yes I think we need a database of bad actors here

Our mission is to help transition us to green, healthy, fun, affordable, and efficient modes of personal mobility, and that's why we wrote this piece!

>That said, in this job market, there isn't much leverage to say no to a prospective job or to make demands of the interview process unless you're already a rockstar.

I don't consider myself a rockstar, or even a prima donna type who would make "demands" of the interview process. But I'm confident I could find a job fairly quickly without jumping through ridiculous hoops just to get an initial response from a company. From my perspective, the software developer market is still a seller's market.

YMMV, of course. Maybe you're in an area where there are more qualified developers than available jobs, and employers have the upper hand to the extent they can pull off bullshit like this.
Their mobile website is equally bad. A gigantic pop-up takes up half of the screen to tell you to use their app.

Third party apps make Reddit so much more usable.
Gofaas looks amazing. Thank you.
Explain how you ask the user whether you can get their IP address when any such request requires receiving their IP address.

This is draconian legislation which unnecessarily causes many more problems than it solves.
It's an interesting timing - Qualcomm just announced major layoffs so it's possible some folks from there will apply.
I'm not going to push this unrelated thing any further than to point out we're talking about two websites who had service suspended on the same day by the same company.

Do you have a source for the explanation?
Comments decrying anything bad in a caustic way are near useless.

Yes. The kind of mentality which is drawn to social condemnation has been a mental substrate to all kinds of bad stuff throughout history. No matter how positive the cause for which it's done, it often becomes toxic and authoritarian. Witness various religions throughout history, as well as the high ideals of the early international communists.
> Assembling IKEA furniture isn’t hard. People just perceive it to be hard before they even try because it’s a meme.

People have different kinds of capabilities, and IKEA furniture assembly may be easier for developer/engineer-types than others.

The components don't have labels and often require careful inspection to choose the right one, based on illustrations that are also unlabeled and low-resolution. Often times the pieces can be assembled incorrectly in a ways that don't become evident until later, requiring disassembly to correct the mistake. I can easily believe that people who have weaker visual-spacial skills and/or are less detail-oriented would find the assembly hard and frustrating.

Someone made a good analogy elsewhere: assembling Ikea furniture has a lot in common with some kinds of puzzles. Some people love puzzles, others tolerate them, and some hate them. That's not "just a meme."
Google Spanner? Not OSS, but globally consistent, scalable, and extensively battle tested.
Vote counts on HN are hidden - doesn't stop a lot of toxic behavior on here.

The problem is down votes are not a good comment tool. Especially combined with hiding and such. Upvote only systems are much more resilient to the kind of gaming mechanics you see here and on reddit.
