Ironically, it was Boris Derjaguin's participation in the polywater debacle that caused many to dismiss him when he claimed to have synthesized diamond by chemical vapor deposition, at pressures far below the thermodynamic stability region for diamond.

In fact, he was right and diamond synthesis by CVD is routine today. We probably lost about a decade of progress in diamond CVD because of Derjaguin's having been tarred with polywater, as it were.

>HN is one of the most respectful communities in tech I've frequented.

I don't think I've ever seen a thoughtful discussion here when the topic relates to gender or race.
I have one of these at work (and my colleague one of the name brand articles) - you don't see the branding on either one 99% of the time, because your laptop is covering it.

Ultimately, it is just a laptop stand, and it's a quality one. I'm just surprised that it took Amazon to come up with a lower priced competitor - I've been looking for something that wasn't $50 for a long time. All of its competitors other than Amazon are overpriced, flimsy pieces of plastic.
Apply HN: Diversity Velocity – Grow Diversity in Your Organization
Problem: Organizations want to increase their diversity. Currently, finding underrepresented people is a hunt-and-peck process fraught with legal risks. There is no way to efficiently reach large numbers of diverse individuals. Thus it takes significant cost and time for large organizations to do diversity initiatives such as hiring.

Solution: Student clubs self-identify by gender or ethnicity. Our solution leverages this fact allowing companies to promote opportunities to these groups. We developed a platform for student clubs that we aim to be their public profile (think in contrast with Facebook Groups). Having profile information enables companies to promote opportunities to specific groups or subsets of people within them matching the company’s interest.

Why we are applying: We have clubs at hundreds of schools on our platform from national organizations such as The Society of Hispanic Professional Engineers, Society of Women Engineers, and The National Society of Black Engineers, etc. We want all these organizations’ clubs and eventually all groups in the world to be part of our network. YC has considerable experience growing market share. We also have several well-known companies paying to use our solution. To increase the amount we can charge and to be more valuable to new customers, we need to have a bigger community. We believe YC is the best partner to help us grow our community.

About us: We are former student club leaders (marketing, rowing, design, bioengineering) who come from diverse backgrounds (Morocco/Paris, Nepal, Indiana, and NY/Boston). Our interests are pretty simple — writing code and talking to customers.

Countless animals rely on mosquitoes as a valuable food source. And before someone brings up the tired "mosquito predators all eat things besides mosquitoes" argument, people eat food besides grains. It doesn't mean we wouldn't still be 100% fucked if rice and wheat went extinct overnight.
Awesome. I got a Qotom Q190PG4 and am up an running.
You'll note that I didn't actually assert the existence of the effect. I observed that a theory which predicts the effect the EmDrive appears to demonstrate, also predicts the fly-by anomaly, and offers a unified explanation for both.

Yes, it requires more confirmation. Much more. I'm not a scientist, but I think that, taken together, it's interesting enough — "Well, that's strange" enough — to warrant further investigation, instead of being all, "Meh. Measurement error."

Am I mistaken in that belief?
There should not be a second class status for ANY worker in this country. Doing so is distorting the labor market and suppressing wages.

If we need more workers then we need more citizens, cut and dry. There shouldn't be this grey in-between - it is a crack that too many fall through.

Ask HN: Our lead architect says 4GB is enough for a developer machine
I work in an alleged data center, building enterprise Java applications. For remote work we're "upgrading" to VDI clients with a single core and 4GB of RAM. I posted on an intranet forum that this was insufficient, and the reply from our de facto Java guru was: "..physical workstations at sadplace only have 4GB and that works fine for most developers. We have made a request for 6GB - that's under review.."

My reactionary response would be something like "Dude, it's 2016. Eclipse, Chrome, and WebLogic max me out" (Yes, WebLogic, that says it all.)

Should I just leave this place ASAP, or has anyone had success in lobbying their company for better hardware? If so, can you give me some tips on how to pull it off? Your tax dollars are involved!
From the RFS entry on Surinam, position 22: "“public expression of hatred” towards the government is punishable by up to seven years in prison under a draconian defamation law. The controversial Dési Bouterse, who became president again in 2010 in an election, has managed to be amnestied for the 1982 murders of 15 political opponents including five journalists."

RFS on Jamaica at 10: " The very occasional physical attacks on journalists must be offset against this, but no serious act of violence or threat to media freedom has been reported since February 2009, a month that saw two cases of abuse of authority by the Kingston police."

Or even Ireland at 9: "... defamation lawsuits are common. Finally, interviewing police sources has been virtually impossible since the Garda Siochana Act of 2005, which bans police officers from talking to journalists without prior authorization."

Not a little biased are we? Amnesty for murdering journalists isnt my idea of freedom of the press, nor are defamation law suits, or a prohibition against interviewing the police.

I have the Amazon one, my colleague the Rain version. When your laptop is on it, you can't tell the difference between the two.

Yes, it's steel instead of Aluminum, which means it weighs around 3 lbs instead of the Rain's 2 lbs (it's thick). Otherwise, it functions perfectly well as a laptop stand, which is all I really wanted out of it.

I think in the aftermath of the US election cycle you'll probably view that differently. Replacing personal and business expenditure with government expenditure is a complicated equation, but Sanders plan absolutely required raising that amount of new taxes. It was probably more of a problem for the Sander campaign that more media wasn't more alarmed by his proposals, I don't think anyone much took them seriously. At least the WSJ was taking his proposals seriously in that article.

I wouldn't categorise H&P as a comedy. There are funny moments in it, but it is much more a drama or a character study than anything else.

Overall I really liked it (except for the ending). I was only vaguely aware of CK as a standup comedian from a few youtube videos I'd seen, so his depth of writing, character creation, and also his acting chops really impressed me.
Using LoRaWan, etc would be enough to power it for months. Also it could probably be disguised as an actual battery and has enough space left to hide high density lithium-polymer battery inside.
If you fix a bug that I'm relying on for the correct behavior of my code then it's not strictly backwards compatible.

The corollary is that you'd be able to measure the size of the universe by observing quantisation effects.

As a consultant (and this situation is very similar for the growing army of contractors out there), it's very difficult to be able to even say specifically what you have made for clients due to NDAs and other legal obligations. I do like this concept, though, for the less-restricted employees out there.

I am curious how you would see this working for something like finance or accounting, though. There are many jobs where you don't produce visible projects that you can point to, but your work has nonetheless been of high value to your employers.
Sure... the same way we robbed the UK of its mechanical looms in the 19th century. The US economy was based on IP theft.

What you say is true, though it would be a sad day when the future of what Canadians want Canada to be is limited by the financial pressure of another country.

Of course, to prevent this problem, Canada could just hint at slowing down or limiting the 12410000000 barrels of oil it exports to the USA [1]

> Firstly, the article was very sexist [...] a thinly veiled pulp piece of sexist journalism [...] a propaganda piece

Even if the article is framed in a way that's not to your taste, the choice here is (1) celebrating how cool these sisters are vs. (2) angry denunciation leading to flamewar #3238. The latter is not a win for HN.

If you can't turn off the ideological rage here, where can you turn it off? And if you can't turn it off at all, then it's not really discussion, just bile. Good discussion, the interesting kind, requires the discipline to resist mechanical triggers and respond to the most alive details in a piece, which in this case is clearly the story of the sisters and what they have to say.

When I'm doing my hobby projects, I'll often prototype on an Arduino UNO with breadboard. Then in "production" I'll buy a stock ATMega328 and a couple supporting components and build it right onto my perfboard.

Great guide here on how to do that.
https://www.arduino.cc/en/Tutorial/ArduinoToBreadboard

If you want even more control, you can just use the avr C libraries with any atmega328, Arduino included.
Go to www.bluez.org and try to figure out how to use BLE. Like how to scan for BLE devices, connect to one and read its GATT, interact with characteristics, etc. Bonus points try to figure out how to do it using their APIs and not command line tools. Good luck! (here's a hint, I hope you like dbus)
Timing requirements don't necessarily translate to _speed_ requirements.

Microcontrollers like the Arduino/Atmel are perfect for situations where you need to guarantee that some signal will be asserted exactly 250 (no more, no less) nanoseconds after some other external event, _no_matter_what_.

Since there's usually no OS running on something like an Arduino, you're basically forced to write very deterministic event driven programs. Also, since most (maybe all) instructions on those Atmel microcontrollers execute in a single clock cycle, you can easily dissect your C functions and know exactly how long they will take to execute.

I wouldn't trust Linux for such an application even with a "real time" scheduler.

Linux as a RTOS certainly has it's place, but it's best left for systems that can actually benefit from the added complexity.

For most typical microcontroller projects, the extra features of a full Linux kernel would just get in the way.

Note: There's nothing stopping someone from using a RPI in such a way as well (bare metal), but they are really geared for more complex applications, so there isn't as much support in that area. Also, the hardware is probably a little more complex. Therefore, my statements assume we're comparing an Arduino to an RPI running Linux.
I don't think Go is Google ignoring progress. It is Google building a language that meets its staffing strategy. Google hires people fresh out of CS programs who studied algorithms and are scholed in forloops for Java/Python/C++.

Go is lingua franca for Google engineers. Google has a stance on DSL's; they're not the way forward.

The mistake is to think that Google developed Go for the larger community. It's out there and promoted to help recruiting. It's not out there for community input on the direction of Go-lang future development.
I work at a medical device consultancy, but we're mostly developing custom Class B/C devices at the bare metal level. It sounds like you'll be developing a Class A device and cost isn't a huge issue so I'd probably recommend going the Android route. Find a reputable supplier who's worked with medical devices before, and check their availability guarantee (since the production lifetime of most Android devices is short).

Class A basically means follow common sense, so as long as document your architecture/design, use source control and test critical parts of the code you should be right to use whichever Android development framework you want.
Wait, what are you talking about? That was in no way a response to what I said to you here. You don't need to change the topic just because you're wrong and you know it.

No one wants that AMD chip in their Macbook. It adds complexity both in engineering and software. There's PLENTY to talk about technically there and why that's a good idea. Not to mention Intel's best-in-class Linux support.
There was an interesting Norwegian documentary that looked into this[1]. The overall observation was that societies where women were extremely free, usually ended up with the same gender distributions as societies in which they were less free (e.g. few women in STEM).

By contrast, societies where women were only somewhat free, the number of women in STEM exploded (although I don't recall if it was quite 50/50). Without considering other factors, it almost seemed like some degree of social pressure to stay out of STEM was necessary to get the most women to be interested in it.

How can that possibly be that cheap even for just the raw components? The AVR chip alone is > $1 even in large quantity. Counterfeit parts?

You mean the chart of video game growth over time?

This might be a bit of a stretch but it has rung true with me and many other people. We all became interested in technology and computers because of video games. Our interests in video games transitioned to taking programming courses in high school and college.

There's TL;drs at the end of some sections.
The best explanation I've seen is that in countries with high economic insecurity, people are motivated to work at lucrative careers with low barriers to entry, despite their lack of inherent interest. Programming is top of the list almost everywhere. The survival instinct surely is egalitarian.

But in countries with less economic insecurity this motivation to work in a field without an inherent interest simply isn't there. Perhaps this motivation is different across genders in wealthier countries (men are more likely to go into fields they don't like), or men simply like technical fields at higher rates.
This is more like asking for a horse with a shiny, touch-screen, IoT saddle.
I live in Colorado, and thought it was going to be the same way for myself and for the general public.

However, over the past year or so I've found it more convenient to visit a store than my "guy". There's a store within walking distance to my home, predictable hours, regular sales and loyalty programs.

All in all, I'm happy to pay more for those things. Many feel the same.

Yes, the black market will still exist- but I think you'll see more local growers fueling the market than south of the border cartels.
Hmmm... I've reflected on my reaction as I was clearly feeling upset about dang's comment.

I have to come to the awkward conclusion that I reacted badly here because I was fairly called on something that broke the rules. I reasoned my way out of my responsibility to be more neutral and in the back of my mind I must have realised what I was doing wasn't the right thing to do. The fact that I felt the need to justify the title choice tends to confirm this :-(

Therefore, I owe dang and I guess ycombinator an apology: first for that last comment where I mischaracterised dang as being threatening, and secondly for the title of this post which was needlessly partisan.

I guess I react badly sometimes to being rebuked. However, that's my issue as in this case the rebuke was fair. I think in this matter my emotions got the better of me and I was in denial - I guess the only good thing about it is that I can recognise the emotion, try to take a step back from myself and then after I realise it's caused by my own behaviour I need to make amends (i.e. I feel sheepish).

So once again, apologies to dang and the wider HN community. I'll try much harder to listen to criticism and I'll ensure this sort of submission doesn't happen again.
The thing is, if thousands use it, then you'd know if it's unsafe...

Yes, and that report indicates a null result. But they also indicate that the driving frequency was way mistuned for the cavity. They were driving it with a magnetron from a microwave oven, which output a frequency far from optimal. This indicates a low-budget operation, and not one in a lab with lots of microwave gear.

NASA, at least, has a microwave source with the right frequency. But they report "researchers were now working on a new integrated analytical tool to help separate EmDrive thrust pulse waveform contributions from the thermal expansion interference". That indicates this thing is still way too close to the noise threshold.

Back when cold fusion was taken seriously, I went to a Stanford talk where a physicist described their attempts to replicate the experiment. At first, he said, they had the apparatus surrounded with radiation detectors and alarms, in case it produced a dangerous burst of neutrons. After a while, they realized that wasn't going to happen. They discovered that the effect being measured was about twice background radiation. Then they discovered that people moving around the apparatus affected neutron readings by more than the measured amount. (Humans are mostly water, and thus reflect neutrons.) Finally they moved the experiment to a "neutron cube" built from lead bricks, where the background radiation was very low. The measured neutron readings went way down. That's what it's like when a phenomenon is near the noise threshold.
This article has some interesting stats.

The last sentence of this excerpt is bizarrely added on.

I've read the report every year and they don't publish their aggregated data.
The questionnaires are filled by local representatives of their choosing.
They had have made political moves which go against their own statements and condemnations and they have quite a few very weird picks that don't even seem to correspond to their own summary of the country.

And while it's true that I can't hold an intuitive understanding of the freedom of the press in various countries I can some how understand that countries where the government shuts down TV stations and news papers all day long probably have less freedom than countries where "organized crime" harasses Journalists.

True, but not quite the whole story.

Some enterprising engineers wrote a cellular protocol stack in ARM assembly language that let everybody use a far cheaper core than anything else.

Very quickly, ARM became entrenched in the feature phones. Then, the evolution occurred to smartphones, and ARM was already in the phone.

Pardon my ignorance, but I don't think anyone seriously doubts that the null article produces no thrust. So it's not a question of whether the null article's production of thrust disproves the efficacy of anything. It's a question of whether the experimental setup which measured that thrust is trustworthy.
