I've made some interesting projects over the years - only a writeup on a few of these, and some are in pieces and in various states of disrepair after moving so much.

Some write ups on larger projects:

1. I used a raspberry pi to coordinate the firing of multiple cameras, and then had the pi upload to a cloud service that would stitch them together to an "infinite zoom" super selfie. https://medium.com/@thekeithchester/gigasnap-
a-prototyping-story-efed72099d32

2. I created a library that made it dead simple for a raspberry pi to communicate to arduinos, and used that to control a lot of hardware projects, like little robots. https://medium.com/@thekeithchester/serial-synapse-94a114aa2...

3. Raspberry Pi's controlled the heartbeat detection (controlled lights and music of your booth) and conductive paint controller (I built it and still don't understand the meaning) for this art piece. https://vimeo.com/207047769

4. I had a video / text message doorbell a couple of apartments ago. https://github.com/hlfshell/doorbell

5. Used one as an MQTT hub for numerous IoT projects. I created https://github.com/hlfshell/mqtt-scheduler to schedule MQTT jobs for things like the arduino powered garden controller (lights + water pumps) I built for my wife. https://github.com/hlfshell/garden-relay

6. This never got off the ground, but when Pokemon Go had first launched and was super popular, I wrote a slackbot that would alert everyone in the office when pokemon (outside of the super common Rattatas and Pidgeots) was nearby. I was repurposing that code to make a portable Pokemon radar that would jump a false account around the area around you, thus hunting down pokemon for you. https://github.com/hlfshell/pokemon-tracker It never got far as the game got super stale quick.
Weavy & Microsoft invites to Hackathon in Irvine, CA July 26-27, 2019
We just came back from Nashville, a fast growing city with 150 new residents every day. We did not experience any of the issues we saw in SF earlier this year (and last year, and the year before that).
Honest question: isn't that kind of separating classes out into interfaces necessary for proper testing? When should you avoid splitting them out to interfaces and implementation classes?
Running piAware for flight tracking

Oversimplifying here, but the homeless probem arises due to high housing cost and poor health care system. In addition to fighting the symptoms (which is already being done ok-ish), we need to fight the mentioned root causes.

Unfortunately, the health care problem goes back to CA or even on a national level. Often times, mentally ill or people that lost their jobs for another reason become homeless, and from there the downward spiral begins. So, a better security net for those who suffer from mental and physical problems would be a good start.
print server for an older printer
https://pi-hole.net. Just installed, very happy so far.
The laws are fine, what we need is to not tailor laws according to selfish political whims or to the whims of publishers and all other inferior competition.

You forgot the food also kinda sucks, just about anything in the Mission beats the pants off the PNW.
Those rates to not appear to be normalized to account for the proportional differences across ethnicities. Based on the 2010 census, ~75% of the population identifies as white[1]. Based on that, the white suicide rate appears to be lower than their minority counterparts. From the link in the GP, based on 2017 numbers:

White: 38%
Native American: 31%
Asian/Pacific Islander: 16%
Black/African American: 15%

The Native American number is the most striking to me because, again, from the 2010 census, only 0.9% of respondents identified as Native American[1]. Perhaps that number is also including Latinos?

I usually roll my eyes at meta comments on HN about ads or tracking on web pages getting in the way, but good lord. This page first slams you with a nearly full page ad with no dismissal, and then after you read a few paragraphs hits you again with a modal sign up dialog.

I'm responding to a post, not choosing a crowd to educate, but in any case, your link in your post below shows that per capita the US and UK (probably most HN readers) rank high. Quoting your source,

I'm totally naive with Raspberry Pi..can someone comment on the following project: Is it possible to put a glass eye behind a portrait of a one-eyed pirate and make its eye move around/follow whoever enters the room? A friend has a glass eye but nothing to do with it.
I know at least a few upper-middle class families whose children went to get some easy, "artsy" degrees at $70K/year.

The parents had their children take on student loans, and bought themselves BMWs at the same time.

Now these kids graduated, are (predictably) struggling to make ends meet, and they may not be able to pay back their student loans.

Should the loans be forgiven in these case, as well?
Who decides when and when not?

Also, the loan money did not only go to pay for tuition - I saw students doing homework on their top-of-the-line MacBooks sipping their $4 lattes all day long. Expensive vacations in some cases, too.
Same in San Francisco... I think we might actually get it built anyway though.
Right now: I use it as a Flashrom rig, for flashing BIOS chips.

The new Raspberry Pi looks powerful enough to use as a media center PC, I ordered one and want to see if it can do that well enough (read as: I’m curious to see emulation performance.)
How Bad Would Nuclear Winter Caused by a US-Russia Nuclear Exchange Be?
For my reference, can you give me an example of properly abstracted code and overly abstracted code?
What a great summary, I could not agree harder.

Some of the worst turmoil happens when suddenly 'business as usual' for customers/users you didn't recognize the full value of disappears, and the front line people have to say things like "the new system doesn't let us do that any more".

You're absolutely right that they'll complain and drag their feet no matter what and that rock-solid leadership is needed to overcome this, but if you at least give them a way to do all the good-for-business stuff they did before in a similar time frame (with an overall faster/better system in the long run, of course), the majority of the sane ones will eventually come around.
> Email shouldn't be used for things that are particularly private to begin with.

To begin with, governments should not be able to access your non-particularly private stuff without an explicit court order.
There's often a strong resistance to
this and I don't understand why.

The suicide prevention features added to my local railway station look like were designed by a prison architect who believed nice views were a major cause of suicide.
It’s not a problem for the really wealthy. If you’re really wealthy and live in SF you live at elevation where homeless are rare. Pacific Heights, Ashbury Heights, Nob Hill, Russian Hill—the occasional homeless person but nothing out of that ordinary.

The homeless problem is a sea level problem.
I was going to screenshot that page. A small auto play video in bottom left corner, a top bar pop up to get the "latest updates from Forbes", an email sign up for the Forbes Daily Dozen and in the background, blurred out is the article.
Pi-hole, and my home backup target using an external HDD and Samba.
Whatever Happened to Moral Capitalism?
I have a small Internet kiosk for one-off browsing and guests.

Currently, mine is running on an ODROID-C2 but the Pi 4 should have more than enough performance for one.

My setup is a stripped down install with a minimal window manager. There's only one icon for launching Firefox which is configured in an amnesic mode. The DNS is set to my Pi-hole.
The magic combination of adblockers has spared me from this fate, but not from an annoying video about the top 5 richest rappers, for some reason.
Do things like the "pass through tax deduction" support this kind of investment. I don't understand the tax implications enough to know what causes the current issues.
Start out doing 30 seconds of running and 2 minutes of rest. Then it slowly changes those so you're running more. If you Google None to Run, you can find a pdf adapted to it, that has an extra day a week.
We use it as a front end to our Church's AV system. It runs a GUI written in Python with PySide that controls our cameras, hyperdeck recorder and vision mixer.

It also controls the power switches for the system, and the blinds.

Absolutely! Put them all in jail, where they have a roof over their head, a bed to sleep, 2 square meals, sanitation... paid for by tax dollars.... errr or some such.

No major or even minor political party is talking about just "canceling" the debt without paying the lenders. The lenders are still going to get paid so this isn't a "taking". The debt is just transferred to the the US balance sheet instead of being held by the student.
I use my Pi2 as a media player (LibreElec), and just ordered a Pi4 4gb which I'm planning to replace my ageing server and NAS with.
If you disable javascript you can read it easily (and much faster, and without ads).
I have a friend who's neighborhood had a community center for the homeless put in, but with strict rules on violence and drug usage. So homeless people migrate to the neighborhood to get into the shelter, but are often quickly turned out because they can't stop fighting or shooting up. And because of this, my friend's neighborhood is now a dangerous, very crime ridden place to live. Two weeks ago he and his wife were leaving for work and a junkie walked around from their backyard, leaned into his wife's open car window and reached for her purse before he could jump out of his car and run the guy off. They're losing their fucking minds over this.
I have been looking at a number of the providers in SaaS consumer email including Proton, Tutanota, Soverin, Fastmail, etc.

It is striking how both Soverin and now Fastmail have a breezy abstract style with colorful illustrations. While the other providers feel like VPS hosting landing pages or enterprise sales pages.

I wonder if the consumer focused brand of Fastmail and Soverin is aspirational or where their customer base actually is.
My big-picture theory of this is anomie[1]:

> The nineteenth century French pioneer sociologist Émile Durkheim borrowed the word from French philosopher Jean-Marie Guyau and used it in his influential book Suicide (1897), outlining the social (and not individual) causes of suicide, characterized by a rapid change of the standards or values of societies (often erroneously referred to as normlessness), and an associated feeling of alienation and purposelessness. He believed that anomie is common when the surrounding society has undergone significant changes in its economic fortunes, whether for better or for worse and, more generally, when there is a significant discrepancy between the ideological theories and values commonly professed and what was actually achievable in everyday life. This was contrary to previous theories on suicide which generally maintained that suicide was precipitated by negative events in a person's life and their subsequent depression.

Just look at when this took off: right after 2008, when any notion that they'd be taken care of and their futures were secure was swept away. The adolescents who came of age during that event will probably spend the rest of their lives with lingering economic insecurity and fear about the future.

What a ridiculous research. In China how many people usually use the email, did you ever research this? You said Japan is different, then do you know how many lost property offices are there, isn't China different? In fact, you didn't want to do a academic at all, you only want a political propaganda, right? Oh, I got an advice that in China the black race never suffer gun shots, will you research this and reach a conclusion?
Yeah we looked at a couple of options, including South East Asia and South America. In the end, the fact that I spoke Turkish, had a cultural connection, the closeness to friends and family in Zurich and the great cuisine did it for us :-)

To be clear, you'll have a harder time if you don't speak (or willing to learn) Turkish in Bodrum, whereas more people speak English in Istanbul.

That's really neat. Please share some details – I was planning on buying a Broadlink IR/RF device for that purpose.
Race to the bottom. This is what millennial are always told. "Well you just need a BEGINNER job, it'll get better". But, there are enough homes for everyone in the country and 20-30 year old homes are fine.
Primarily, an always-on node to run wake-on-lan (via etherwake) on other home network nodes, and to act as an SSH bastion when other entrypoints are failing.
I used mine as a dlna server and file server, but I was constantly having to restart it or delete the database to get it to pick up new files I had recently dragged on to it. Has anyone been able to use one successfully for serving media?
I just got an "NL Alert" about this, some kind of faux SMS sent straight to my phone. With a WhatsApp number, an alternative phone number, and a Twitter account. They seemed pretty well prepared. Emergency service via Twitter! Call me impressed if they can pull that off.

If you're interested in native CRT output without the quality hit of composite video, I'd recommend taking to a looking at something like the Pi2SCART: http://arcadeforge.net/Pi2Jamma-Pi2SCART/PI2SCART::264.html
Can't remember where, but I remember reading stats that a huge percentage (like a third) homeless people are military veterans :(
I use them as controllers/monitors for remotely managing a 3d printer farm. At about $40 total extra per printer for the pi and associated hardware, and an open source utility called "octoprint", i'm able to remotely upload, monitor, cancel/pause, and have a camera feed to each printer. They also give some additional nice-to-haves by allowing me to upgrade the printer firmware remotely, and get very accurate print completion estimation times.
no, if you download the package that still works. you have to format the package name as a filepath instead of just the name so you have to use that ./ in front of it (assuming you're in the same directory) but that's all the more it needs.
At least the holodeck cut down on the amount of inexplicable time travel, theme planets, or theater-loving superbeings in order to get to the alt-history episodes. That excised a big source of random woo, and replaced it with one frequently malfunctioning plot device.

If the writers of the original series wanted to set something in Victorian England, they had to invent an Victorian England planet, and then they could only use it once. The next generation writers could decide Data liked Sherlock Holmes, and have that be his recreational holodeck thing, just like Captain Picard had the hardboiled-detective noir novels.

I thought the position of ship's counselor made sense, but not as a psychic bridge officer. That seat seemed more suited to a crisis negotiator type of person--the kind you'd ask to talk the aliens into powering down disruptors and releasing a hostage. Instead, it was "I sense anger and frustration, Captain."

And Guinan trod perilously close to the "magical negro" trope at times, and definitely embodied the "the bartender" trope.
Disable Javascript on the page, and you can read it without a problem.
Awesome. I would definitely give it a try.

And I totally agree; the community has grown exponentially. I have been following the graphql since 2017 and am totally amazed by the power of community and growth of GraphQL itself.
Yes they have. You can ride them in San Jose.
> Is this proof of Riemann hypothesis?

It claims to be.

That said, I very much doubt it. There are lots of papers out there which claim to prove RH. So far, none of them have been correct.
I'd add in the importance of understanding your code. Sometimes we do such a good job of breaking our code down into bite-sized chunks (components, etc), that coders can lose the big picture of how the app truly flows.

I've seen coders spend hours debugging problems, stepping through line-by-line in their IDE, and not finding the problem. Then when I suggest they stop, step through the creation of the bug, and just think about what algorithms and data changes are occurring at each step, they often have an epiphany and realize where the problem must lie.

By all means, use the tools that are at our disposal, but the most important part of debugging is simply to think.
Why not test the civic intelligence of using chopsticks around the world? This article really made my day of such unscientific research can really appeared in the science. How ironic it is.

Their app has push capability, as far as I know that has been used as well.

They have a very wide reach.
Mine is running in my attic, hooked up to three antennas on my roof:

1. A GPS antenna which provides an accurate “stratum 0” time source. The pi runs ntpd and provides time for all devices on my network.

2. A home built ADS-B antenna for receiving position reports from local aircraft and airliners. Interfaces to the pi with a USB SDR. Pi runs dump1090 to provide a web visualization of local air traffic. I also feed FlightAware with this info.

3. A home built VHF antenna for listening to airband transmissions. Second SDR. Pi runs scanner software and an IceCast server for clients on my network to connect and listen.

The pi also has a temperature sensor that logs once a minute so I can plot my attic’s temperature and I can have it alert me if it gets too hot.
Small languages are more likely to die than food.

Knowing a small language is a disadvantage: you have to put forth the effort to learn it and some other useful language. You are better off learning the language with a larger base of speakers and playing games (or finding food in poor areas). Language is about communication, if you can communicate it doesn't matter what language is used, if you can force the other person to use your language you don't have to put for the effort to learn a second.

Parents want their kids to have the best: that means they will make their kids learn the common language of their area. The grandkids generally are the last generation of this that speak the original language because it is no longer useful when everyone they know speaks something else as well.

Food doesn't have that pressure in general. Family recipes passed down for generations are a thing. Everybody needs to eat and what doesn't matter. Some people enjoy unique flavors so there is a slight advantage to knowing how to cook something "weird".

偏见源于无知
TLDR; of cons from various sources:

- New SoC puts out more heat. Active cooling more important now.

- Video playback at 4K requires H.265

- Micro-HDMI cables now needed.

- Draws more power.

Other than that, looks like a major performance boost.
I don't use it, I never got around to it because I'm not actually all that interested in computers, at least not in the sense that I thought I was.
My Raspberry Pi 3 works as a CUPS print server connected to a laser printer, as a pi-hole DNS server to filter ads, and as a ssh entry point (with dynamic DNS). I would use a Pi zero, but Ghostscript is not too happy when printing large documents on a single-core processor with 512 MB of ram. I still have to find the time to set-up a backup server on it (and decide which software to use).
Just because Microsoft has made some free stuff recently doesn't mean I'm going to switch stacks all of a sudden, when there are comparable frameworks I already know.
What software do you use for your setup?
> drugs, you can bet that Amazon would suddenly become capable of identifying and preventing the sale of illegal products.

Although they probably still wouldn't face any legal liability, going back to your parenthetical comment "not surprising".
Lemme think. A camera that observes the room from the portrait, anyone that walks in is a dot on a plane, and it points the eye at the point on the plane. Should be doable. Yes, the Pi should handle that fairly easily.

The part that you'll have to figure out is making the eye ball rotate. There are GPIO pins on the Pi, so you can get the commands out, but you'll need to build the eyeball component yourself.
Cool. Good to see the privileged viewpoint of white folks still exists. I'd imagine it's much easier to judge others over the internet that to actually find ways to help them. And yes I'm being purposely judgemental of you. Have you taken the time to understand why these states happen for transient folks? Our mental health system is broken and the federal government refuses to grand basic health care for all its citizens. The state does offer free health care, but you have to jump through hoops to get it. As a former person who was homeless, I got to experience it first hand. Also just because you happened to work in the common areas where the homeless are gathering doesn't mean nothing is happening. The city is trying things but often they are only able to help a small percentage. And are often hamstrung by lack of funding and indifference by the larger population. Drug use is rampant because they want to feel something to escape the shit situation they are in. They just lack the care and monetary means to move on to get help.

So in short, fuck your shortsided indifference.
Of course the difference in "punishement" is huge, but the important and scary part is that corporations can have a huge control on how people behave without any threat other than "you won't be able to use our service". That was my point.
I really like this pattern, but unfortunately some people consider it confusing when the closure capture is not explicit. C++ lambdas are nice in that regard.
