Ask HN: Anyone with experience dealing with Shenzhen electronics manufacturer?
I've made contact with a Shenzhen electronics manufacturing company and got an initial quote to get some electronics designed and built. I want to have 1,000 units made initially. The device is a small single board computer about the size of a (big) thumb with a handful of chips and i/o ports. The company is very experienced in building devices that are very similar.

Is there anyone here with experience dealing with Chinese electronics manufacturers willing to offer me some wisdom about how to succeed in my dealings?

Their initial quote is $3,500USD (which I believe is for the design only, but I have emailed them to confirm) and they've said that the BOM for a single unit is $25USD which seems a little on the high side but approximately right.

I'm wanting to understand things like:

If the single unit BOM is USD$25, what should I expect the approximate price to be for 1,000 units?

what approximately should it cost for such a company to do the electronics design according to my broad specifications? Is $3,500USD too high?

should I be negotiating on the price that they have offered, and if yes, how do I negotiate in a manner that is respectful and polite yet conveys confidence?

how can I best lock down the 1,000 unit volume pricing for the item I wish to have manufactured, before committing fully to this manufacturer?

what's a good way to learn (fast) how to work with Chinese culture in a respectful and polite manner whilst also getting the job done to a successful outcome.... any books?

Any pitfalls or tips in particular to look out for?

thanks in advance!
Activists Must Stop Harassing Scientists
agreed : "too much information kills information"
A lot of people in this thread giving their personal experience, but failing to realise they're doing exactly the same as people who promote crystal healing or homeopathy.

Depression is an umbrella term and it covers a wide range of experience. Some people will recover even if you do nothing to treat them; others will recover if you do anything (such as providing homeopathy) to treat them. Correcting for this is difficult, which is why respected organisations disagree about whether exercise works or not.

Felipe suggest that publication bias explains why other analyses don't show benefit of exercise as a treatment, but that doesn't make much sense. The only reason he sees such large effect sizes is because he includes huge amounts of low quality research.

When you restrict the analysis to good quality research the effect reduces and it's much harder to see any difference between no treatment and depression as treatment.

It's not particularly suprising that physiotherapists and sports therapists think what they do works. What is somewhat suprising is that HN routinely falls for it.

Rectified this on my website, and apologies to parametrek for getting it wrong (and suggesting the project failed). Only found some sparse information online, and failed to do my homework properly after that. It's a pity hmexx didn't share too much of the results, would have been an interesting piece of information.

Sorry parametrek, didn't intend to bash your work - you obviously did better in the side-project business then I did so far :)
I wish GitHub had web push notifications. I'm happy that Reddit has them, but they barely work to be honest. Sometimes it seems to work, most of the times it just doesn't.

From that article:

black doesn't reflect enough light for optical scanners to identify recycling codes, making it difficult to sort these types of containers properly

I wonder if this is similar to the "face recognition doesn't work on dark skin" problem --- there was a lot of planning and design involved in the systems required to process the plastic, and even testing, but no one thought to test with black until very very late in the process?

Given that people already have to sort the different types of trash, isn't it not too unreasonable to ask them to sort the plastic too?
> Serious question though: has anyone here ever used the notifications for anything other than web based IM (slack, whatsapp)?

I'm building a tool that uses browser notifications to ping when something new is created. It only asks for permission, when a user clicks the button which is clearly labeled to "setup browser notifications". It also sends only 1! notification until the browser tab is opened again, to not spam.
But it shows that it's either so easy that there's no barrier to entry (I doubt it) or that no one can deliver a really convincing product.
So everybody used to be schizophrenic?

I know the bad connotations of schizophrenia are more present in modern societies, but still, I can't see how a primitive group of schizophrenics would be able to thrive.

Is there any proof or actual need for this bicameral mind other than trying to explain the religious phenomenon?
Surely you’ll be accused of whataboutism.

And they’re right. Two wrongs don’t make a right.

And if India is wrong to do test, she’s right to dismiss hypocrites.
My issue with this is that in a way it gives strength to their argument - i.e. segregation reinforces the concept of there being a fundamental difference between the two groups.

Have you used Firefox? A notification about telemetry is shown on-screen the first time you launch it, including a link (or maybe button, I forget) taking you to the settings page where it can be disabled.

If you're talking about telemetry collection in general, and not specifically Firefox, then nevermind.

I don't find telemetry bad in any way, provided that it is non-identifying telemetry, so I don't mind that it's on by default. There should always be an option to turn it off for those that want to.

Many, many more applications collect telemetry than people suspect, and for every application you know of that collects it, there are a dozen that collect it without telling you.

You are right about notifications being over used. We've all gotten notification fatigue, now, because every website thinks it's own notifications are super important. I want notifications when major news events happen, when my wife texts me, and for nothing else. I do not, and will not ever, care to be notified the instant a website has new content.
The first two are a feature for me. Not to mention not being crippled by Xilinx 'IP Core' DRM.
But that's exactly what the article is saying isn't as intuitive as you think it is.

> it's not at all clear that it's against the law
I have a self-hosted home automation platform with a web UI that uses web notifications for tons of things around the house (for example, a notification shows up on my device if the front-door camera notices my face, and the notification has 2 actions I can take right from the notification: "Turn on the outside lights" and "unlock the front door").

I also have it enabled for a website that sends out notifications when they go live for their podcast, the google play music site has them enabled for me to show song titles and album art when the song changes, and Circle-CI has them turned on for when builds pass/fail, but for some reason that one only works when I have the tab open...

That being said, i'm more than happy with this new UI! It's easy enough to find that sites can implement directions for users to go enable it if they want, and it's not in everyone's face for every news site that spams asking for it.
I use Evernote for anything that is relevant to others in my family. We can keep each other up to date on things like shopping lists and trip planning, family events or projects. Plus take notes. It’s one of the only apps I use and pay for. Chose it because it works on all devices and is simple. They could handle syncing a little better, when a change is made on two devices at once. But the almost unforgivable sin is that they don’t have a calendar. It’s hard to use a tool to organize your life that doesn’t have a calendar.

I hope they stick around.
I'm scratching my head at this one.. I installed it, it claims that VPN is on, there's the little key in the status line as when e.g. OpenVPN is running, but pointing a browser at whatismyip.org still shows the same old IP address. So, no VPN after all?
Part of the problem with starting that here is that many railroads have to just stop roads dead for 5-10 minutes every time they go by. Even if it's a fast train and it's 2-4 minutes, that would cause a crazy traffic increase here, because you've just lost between 27 and 53% of your roads' capacity.

My experience trying to get approval for an App that uses G Suite API
Given the three things I noted, I take it that it meets the definition of prejudice, per Google:'a preconceived opinion that is not based on reason or actual experience'.

I don't mean prejudice in the sense of being prejudiced against minority groups. I mean it in the literal sense of the word, i.e. an unfounded prejudgement.
> Make it voluntary and there would be no problems at all.

Unfortunately that would make the telemetry non-representative. That said, it is opt-in when possible, if you consider "using Nightly" as opt-in (it's clearly explained before and after installing Nightly).

> You can just start a browser, visit top 1000 popular sites and count how many of them show the popup.

That doesn't tell you anything about what behaviour led up to a permission request that got granted vs the 97% that got ignored. Furthermore, it wouldn't have told them that the notification request is denied far more often by users than the webcam/mic request.

> Also, it seems like everyone tries to abuse notifications. For example, Youtube app shows a notification when the channel you are subscribed to releases a new video. Is it so urgent, that you need to distract the user? They could show this information when the user opens the app.

It would be nice to have data on when users revoke permissions again as well, indeed.

Also I would say it might a difference in priority: one game could be designed to be as fun as possible, which might cause it to be addictive to some player; whereas a F2P game would optimise in addictivness first and foremost, since its business model rely on it.

This was demanded by Elsevier and Springer, as the copy of the order shows https://torrentfreak.com/images/scihuborder.pdf . Every researcher who still is an editor of one of their journals is responsible for this.

People should know that all of these people who support this are paid from their pockets.
Honestly, CRDTs are quite complicated to understand. No amount of blog posts, research papers or diagrams will truly click (for most).

And like somebody else said in comments, most articles on CRDTs assumes the audience are math people. I'm working on a series of blog posts that slowly uncover how real-time collaboration algorithms and data-structures work – with all the necessary math concepts explained in simple terms first. Will publish them out as soon as they take a good shape.
Yup, thankfully there are some great alternatives now.
They could simply require the dmca process be used instead and not even get into the middle of it.
The author (what's his authority, by the way?) agrees, though:

> Well, it can't sell "copyright licenses," as that is a misrepresentation over the rights that Getty Images has -- but if it wants to try to get people to pay for stuff that is otherwise available for free, that's Getty's prerogative.

His point is that he does not think that Getty was selling licences. However Getty's past behaviour (and I'm sure their own website since I'm sure that the T&C and the licence are attached to any sale) suggests that this is exactly what they were doing:

> The first one was brought by photographer Carol Highsmith, who sued Getty after Getty had sent a demand letter to her over her own images, which she had donated to the Library of Congress to be put into the public domain.

And yes, knowingly selling licences for rights you do not have is against the law. If you think it's not then I'm happy to sell you a licence to fish in the River Dee...
Fascinating. I've often thought about how purple relates to violet, but never really figured it out.

There are of course colours we call violet that we make by mixing red and blue. For example, the colours in this very article, which use RGB colours to mix red, green and blue light to create violet. So the violet in this article isn't "true" violet at all; it's just a faded bluish purple.

So are there real world paints that are actually violet? Or is the violet from the rainbow something we cannot truly reproduce, and only fake by mixing red and blue?
Thank you for tying that to a user action, and not page load.
"The most obscure part of Microsoft's history." That's a pretty high bar.

Here are a couple other candidates (restricted to stuff that actually shipped as products):

* QuickPascal - Microsoft's low end Pascal competitor to Turbo Pascal. (The full MS Pascal might be a reasonable candidate too.)

* MS Access, the communications package. (Predates the database of the same name.)

* Softcard - Z80 coprocessor board for the Apple ][. (The Mach 10 and Mach 20 PC accelerator oards arn't bad choices either. The Mach 20 was a plug in board for PC's that itself had expansion slots.)

* Multiplan - the spreadsheet precursor to Excel.

* The runtime-only version of MS Windows. (Bundled with Excel to let people that didn't have Windows run Excel.)

* Visual BASIC _for DOS_ - Exactly what it sounds like, but running in text mode DOS.

Some plastics can be recycled by simple melting - thermoplastics like ABS. Unfortunately they're often mixed with additives like flame retardants that cause problems.
This is an idea which has been popularized by the new TV series Westworld. It is interesting, however it is not the topic of this paper, which does look instead into sociological perspectives rather than an internal psychological theory which is difficult to be approved.

Jaynes' theory may have merit, but it isn't that relevant to this paper, which is an empirical research paper on social data and theories.
The example of approximating 123 x 456 with 100 x 500 tends to undermine your point a little. It's too simplistic and the answer isn't even within 10%.

120 x 500 gives a much better approximation, and just needs you to know 12 x 5 = 60. Better still would be 125 x 460, which is 1/8 x 46 x 100000. That's within 3% of the true answer, and all it takes is quickly dividing 46 by 8.

It's very helpful to be on good terms with numbers less than about 100, which is why the multiplication table is taught. It's useful for reverse calculations (like 46 / 8) as well as forward ones. Decimal equivalents (1/8 = 0.125) are worth learning as well.

The key to being able to quickly approximate things is to populate your mind with memorized values. They work as landmarks (so the 7x8 example, in conjunction with the decimal equivalent of 1/8, means that you know almost immediately that, e.g. 55 x 125 is close to 7000).
India isn’t stupid. They demonstrated to countries, including one that recently (1970s) threatened to nuke them to the Stone Age, their capability.

The country that threatened them with nukes is crying afoul, while creating a space force to more easily nuke countries.

Sell the hardware for profit, give away the design files under an open source license. Assembled ready-to-run hardware is a serious value add on top of an open-source hardware design. A strongly built brand should also be valuable in such a niche. So I'd look mostly towards trademarking of the brand as IP protection mechanism for such a project.
Do you also spend a lot for real world items?
Well, practically, there absolutely is a difference. You can host above-board content any way you like, even on things like IPFS, and tell anyone who makes fraudulent copyright claims about it to sod off-- but if you're not being totally above-board, you won't get that luxury. It's a very different trade-off compared to the likes of SH and LG, and one that's quite valuable.
My hunch is that because most women had more children (on average) than contemporary women in developed countries, they either had the miscarriage after they'd already given birth to other children, or at an early age, with still plenty of time to have more children, absent serious health issues.

I recall typing this exact game into the old Amiga, in the AMOS Professional interpreter, from a code listing in some magazine. It was not a very long code listing, but significantly more than 960 bytes! It had sound effects, too, and I think it scrolled the opposite direction. I guess that made it a racing game, not a skiing game.
>When journey times are less than four hours, people usually prefer to travel by train instead of alternative options, such as air or road.

I'm sure the airport security theater plays no small part in this. Would you rather sit on a train for four hours or spend two hours at an airport, get treated like cattle, get told you can't bring X Y or Z past security, get felt up by a stranger, and in a cramped tube for an hour? I'll take the train every time.
How do you write tasks?
"Things like deadlines, status reports, daily standups, open offices, tickets, and retrospectives are designed around the assumption of a reluctant workforce who have to be clubbed into line."

I recently read a RAND Corporation research paper from the early 90's about command and control, and it gave me new insight into how a C2 system supports a commander (or in a business case, the CEO).

The things that you mentioned (status reports, daily standups, tickets) are not for "clubbing the workforce", they are for feeding information to the CEO/commander about 3 things:

-does the organization understand the plan the way the CEO does?
-is the organization executing the plan correctly?
-is there information that requires the CEO to change the plan?

It's not about "the beatings will continue until morale improves".

Honestly, from my perspective (trained as a psychologist), behavioural economics is essentially running social psychology experiments on economic behvaiour.
