For this age group we need to get away from the idea of mental illness and focus on things like rapid onset despair. Another reason we need to move away from the idea of mental illness is that there's considerable stigma around mental ill health, and this is a barrier to help-seeking.

By and large, a domain is less than 20 euro a year. You can come up with alternatives, but is it really worth it?

The hard part of domains is dealing with trademarks. In recently years it has been remarkably quiet in that area. Which means that ICANN is doing something right.

I don't particularly like ICANN, but the ccTLDs and legacy gTLDs are very stable. Which is a good thing.
Yep, I just received it on my phone, which wasn't fun because I was listening to music, my phone blasted the emergency tone at full volume through my earpods. It really hurt :(

Anyway, good to see that the emergency system works. I just received a second message with a whatsapp number and twitter handle which you can use in case of emergency.
"Avoid Indirection in Code" is a foolish thing to advocate, and the example provided is more confounding than explanatory.

Abstraction is the key. Abstraction can be used to reduce incidental complexity by hiding an implementation. Abstraction can be used to reduce the cognitive load of the essential complexity by making the code look like the problem domain.

But there is a cost to abstraction. A person reading your code may not have the same mental model of the problem, and might’ve be working at a higher or lower level of abstraction, in which case the "indirection" might be a stumbling block. Weigh these costs carefully.
If I hadn’t started this startup and had time, I would want to start making this right now
Toy Story 2 Got Deleted Twice, Once on Accident, Again on Purpose (2012)
I highly recommend reading the actual audit[1]. There's a lot of good details in there, similar to the Senate report on the Equifax breach a few days ago. There were several problems: the inventory tracking issue was particularly enlightening:

>system administrators did not consistently update the inventory system when they added devices to the network. Specifically, we found that 8 of 11 system administrators responsible for managing the 13 systems in our sample maintain a separate inventory spreadsheet of their systems from which they periodically update the information manually in the ITSDB. One system administrator told us he does not regularly enter new devices into the ITSDB as required because the database’s updating function sometimes does not work and he later forgets to enter the asset information.

Other good notes

Lack of training:

> NIST requires that organizations provide security-related technical training specifically tailored for their assigned duties... As of April 2019, JPL did not have a role-based training program, provide additional IT security training for system administrators, nor fund their IT security certifications.

Refusing to let Department of Homeland Security (DHS) complete a thorough post-intrusion assessment:

>However, according to NASA SOC personnel, JPL was concerned with inadvertent access to its corporate network and feared disruption of mission operations. In addition, JPL was unfamiliar with DHS’s standard engagement procedures. Collectively, resolution of these issues resulted in DHS being unable to perform scans of the entire network until 4 months after the incident was detected.

Why does it matter to you? I mean, I know why I find it to be a positive: implementing a runtime is a vast and complex task, and doing it well is way too expensive for most projects (see for example the problems Python has had over the years with the global interpreter lock).

If you can use a runtime with gazillions of man-hours invested into making it better, and get easy access to bazillions of native libraries, why not?
Do you think you got any benefit from the aforementioned medications? If you did then maybe it was luck that you did not incur the negative side effects and yes, any profit generating device is to be a a bit distrusted and treated with somewhat skepticism.
But this isn't preventing only suicide -- it's one part of a package to reduce suicide.

It's a very important part, and you must have reducing access to means and methods if you want to reduce the numbers of people killing themselves.
I've lived in Northern Virginia, and I've seen all-cash bidding wars for houses worth north of a million. I'm glad you were able to get to a price point where you weren't competing with flippers. Where I am, I can't see myself ever reaching the point where I can make an accepted bid on anything.

Low-cost Aarch64 development machine! I run Aarch64 Fedora on a Pi 3B+ for porting personal projects to Aarch64 and for testing. When mainstream desktop ARM arrives (ARM Macs perhaps?), I’d like to be ready in case I have to make a switch from x86-64.

In general, student loans in the US are no longer private loans. The federal government essentially funds all student loans in the US for the last ten years or so as I recall.
I wonder if there is a correlation between the increase in suicide and decrease in religiosity.

I'd imagine suicide is a much tougher sell if someone believes in an eternal hell for suicides, and an eternal heaven for those who hold onto hope.
Migrating User Defaults Data to an App Group – iOS Dev
I'm building a CarPi. I'm using a bluetooth OBD-II adapter and Python-OBD to monitor my car's diagnostics and record them. I'm planning on adding a GPS adapter and probably a gyroscope/accelerometer so I can track location and motion at the same time.

It's mostly just for fun.

Maybe one day I'll add some kind of analysis to it. It might be interesting to track location, motion, and car status in order to predict mileage or if the engine light will turn on.
Your study is ridiculous, most people may not consider these as wallets, and there are various ways to return, your metric is very unilateral.

The Beltline is really great but it wouldn’t be what it was without the other projects in the city like Ponce City Market, Krog Street and a few of the other areas that were once isolated “islands” of restaurant/shopping space.

I had a feeling the Beltline took queues from NYC’s Highline, just as Ponce City Market, Krog Street Market, and the new Marietta Street Market took queues from Chelsea Market (surprisingly owned by Alphabet Inc.). Turns out I am right and they hired the same Landscape Architecture firm as the Highline[1].

The sheer scale of the Beltline dwarfs most other projects. I was looking forward to the connection with Dekalb PATH but I moved to Cobb earlier this year.

Every cheap country (Vietnam, Nicaragua, Thailand, Bali, etc.) will have a hodge podge of backpackers, ex-pats, retirees, etc. Enough locals will speak English to support providing necessities and socialization can happen with the other ex-pats.

Working there is a different story, but generally you don't want to work there since the reason they're cheap is that the people are poor. The local jobs are low paid. The trick is to be able to work remotely or more rarely as a well paid employee of a foreign company.
I used it as a ad hoc game camera last summer (we had something coming through our back yard, so wanted to see what it was, and I won't say no to buying more electronics I'll use once), but that's about it. Been powered off ever since.
Doorlocks of our hackerspace has been RPi controlled almost since the original RPi came out, maybe 2013. Nowadays we got 4 doors on 3 RPIs (internal and external), with over 200 members that has access. Using MQTT to communicate with our membersystem since 2016 or so.
You framed it as people who don't deserve a break--for reasons related to values like prudence and thrift--getting a break anyway. Fine. If some people did act virtuously but are still in tons of debt, in what way do they not deserve a break? Why bring up the Goofus and Gallant scenario at all? The question isn't whether people deserve loan forgiveness, it's a question of what's good for society as a whole.
I sold a company and the hardware wasn't included. I have a bunch sitting idle, plus about 1500 RFID tags and 20 readers. Takes up space but I can't get rid of. Should sell them.

Without any strong opinions on the matter (I am not a RE investor), I do find it weird that all the blame is going to the investors when, as you pointed out, the reality is that the market prefers to rent vs own. Should we not "blame" younger people who prefer to rent as much we blame investors? If "normal" people are having trouble purchasing a home, isn't it because a lot more people prefer to rent?

Personally, though, I don't believe that younger people preferring to rent is making that big an impact. That's something you see in only a few cities in the US, and most investors who are trying to make money via rentals actively avoid those cities (saturated market).
I'd love to run something like this, but I recently switched to ZFS which recommends having a lot of RAM (my NAS has 4GB). It's what kept me from going the route of the Helios 4.
you do you but i'd highly recommend moving to a non-income tax state (and city) beforehand, alongside drivers license, cell phone bill in new place, etc. NYC and NYS tax authorities are getting more and more relentless as upper/middle class ppl leave the city, so you'll need serious documentation that you aren't just leaving and coming back soon if you want to avoid getting stuck still paying them.
Ahhh, but not with anti-sweat technology :)
I used mine as a NAS for a while with an external USB HDD and a samba share. It was also set up to be a VPN and pi-hole. I have a pi zero that I use to flash coreboot on laptops.

My PS3 isn't doing so hot as a media server client for my NAS's movie library - the network connection is poor, the interface is fiddly, and it can't load subtitles embedded in files. I was going to buy a pi3 to replace it as a media server client and hook up an external DVD player, but now I'll be getting a pi 4!
It gets stuck for a minute or two on 100%, then says that some trackers cannot use https and makes you click another link to finish the process.

I wonder why these dark patterns are still acceptable on the web. I thought opting-out was supposed to be as easy as opting-in according to the GDPR? The vast majority of sites I see make opting-out a very difficult process, usually hidden behind a tiny grey span of text, while the opt-in is a giant green, frictionless button with immediate effect.

Usually there is misleading title like "We value your privacy", and a giant green accept button making you think you're agreeing with that statement. Then a tiny "Other options" in grey somewhere at the bottom which makes you go through sixteen confusing modal dialogs.
Same story here. I went to US public schools and British grammar schools. The latter are no joke and much more stressful. US school I could mess around and still maintain perfect grades.

This is interesting and compelling. I wonder about spambots though, when authorizing a service exposed to the web. Doesn't it get expensive pretty quickly when a bot decides to scan the site and floods it with requests that all exception?
The problem with that is that game will have the Ingress/PGo/Wizards Unite problem of limited activities outside crowded urban areas but 1000-fold because you're adding physical infrastructure. And on top of the issues of just getting them out there there's the other issue of just coordinating placing all those locations and making sure your infrastructure doesn't get ripped up for being an eyesore or for angering some local politician.

One alternative might be to combine multiple location sources, eg: GPS, local wifi and cell tower data to cross check. Spoofing all those at once should be harder but the OS would have to support lower level access to the location info. In a similar vein there's probably some way to validate the GPS info if the app had access to the incoming signals more directly as those and the slight jitter coming from reflected GPS signals should be harder to spoof.
that's a harsher reply that it needs to be, mate
The third alert included the Whatsapp number and twitter address for the police.

There have been three alerts in the past hour. I'm hearing other people's loud phone alarms go off outside, several minutes after mine, so they weren't all sent out at the same time.
San Francisco is a net-exporter of homeless people, according to a piece by The Guardian. Aproximately half the homeless population was sent to other states.
It is the same kind of format as the Amber Alert things I used to get in the states. How do they push that out? Based on location, cell tower usage, sim card?
You could probably automate cutting the power with a relay switch also connected to the pi. Just scrape weather data, and if you expect the storm, trigger the switch.

1. simple server for backup and git repos

2. xbmc for videos on main tv

3. retropie (I had fun with this for about a week but haven't used it lately)

4. pihole for blocking ads and time-wasting sites

5. various small projects: security camera, motorized window shade, etc.

I run Home Assistant on my desktop to communicate with a few of the other devices in the house but I might move that over to a Pi so I don't have to worry about restarts and performance. I'm thinking about consolidating this setup somewhat but I'm waiting for my next move.
I run minidlna on it to host music. No issues scanning for new files, but IIRC detecting new files was an issue when I ran Plex under docker on it.
So while Matrix itself is an open source project backed by a non-profit foundation (https://matrix.org/foundation), the team who started Matrix created a startup (New Vector; https://vector.im) in 2017 in order to hire the core developers and ensure we could keep working on it fulltime (and also to dogfood the protocol and ensure that you can build apps on it that people consider useful enough to pay for). The Riot app (https://riot.im) is made by New Vector, and Modular (https://modular.im) is the hosting service New Vector provides as a paid Matrix hosting offering (using Riot as the default client). The proceeds from Modular go directly to paying the Matrix core devs employed by New Vector, and so massively benefit the project. Sorry it's a bit complicated; turns out that funding opensource is not trivial...
Why Drug Interdiction Is Doomed to Failure
This has happened several times over the past couple of years in Belgium as well. Bugs and mishaps happen, and I'm sure the systems were designed to be fault tolerant. But perhaps it's time to stop relying on POTS alone for emergency numbers? Is there any particular reason we can't reach emergency services over the internet? Even something as banal as Skype or Facetime would make for a decent backup.
I discussed this recently here on HN [0], the fake spinner is a dark-UI to 'punish' you for opting out. If you just accept the popup disappears immediately.

I got a RPi 3B+ to build and test some open-source amateur astronomy tools I contribute to - everything has been working quite nicely so far (I use Fedora on my computers and it also works fine on the Pi). I'm eyeing the RPi 4 with interest.
>It's strange that a rich area can't take care of this problem.

Apparently, it's a really difficult problem that nobody has really solved.

Yes, San Francisco is wealthy. And Monte Carlo is wealthy too with Lamborghinis and Ferraris. Why does MC not have a rampant "homeless problem"? Well, if a homeless person tried to lay down a blanket to sleep on the sidewalk across from the iconic casino, he's going to be rounded up by MC police. As far as I can tell, MC doesn't have a homeless shelter so I'm not sure where the MC police takes the vagrants. San Francisco police obviously do not remove all homeless people from the sidewalk. And nobody is suggesting SF emulate what MC does.

Can SF spend money on housing for homeless? Multiple cities have tried this with mixed results[1] ... poop in the stairways, drugs, etc.

Which city in the world has the best homeless program (especially dealing with mentally ill homeless) and what do they do differently?

Where's the indifference? They just said they moved away from it. Do you have a problem with that?
EXTREMELY UNFAIR to China!!
This paper isn't great.

Yes, I can use a custom in-memory data structure, write it in Go and cluster it using some nice Raft replication. It's not all that hard and it's much, much faster than Redis. (we do this at Stream for activity feeds and chat)

For most apps doing this is totally impractical. If you're using PHP, Python, Node or Ruby for a small to large (anything that doesn't have 100 million plus users) the overhead of implementing the pattern the authors suggest is just too large.

I think Redis will only keep on becoming more popular...
Yes college is like crack cocaine. The lives I have seen wrecked by it is amazing. Just the other day a good friend of mine was talking about getting his hundredth PHD. He was looking into possibly Quantum Mechanics next. Such a powerfully addiction. We need to make sure education is incredibly expensive if we want to keep our young kids safe from it. /S/S/S

Raspberry Pi 4: Finally Fast Enough for a Web IDE
The coffee machine in our office is controlled by blockchain NFTs and a Raspberry Pi:

Once authenticated, an owner of the NFT can select their coffee type on their phone which then signals the Raspberry Pi to make whatever coffee type was selected by jumping the contacts that used to be pressed by the machine's buttons (which have been removed).

It's a cool gimmick, fun to show off to visitors, gives us a nice record of who is making coffee (since each NFT's owner is unique and trackable), limits users to those with the NFT without us having to build usernames/passwords, and is also how I make my coffee each afternoon.
SF spends $250 million in 2017. 1/3 on actual homeless, 2/3 on preventing homelessness (e.g. rental subsidies).

That seems unduly harsh. He left somewhere where quality of life was poor and moved away to a better place. He was honest about his reasons for leaving too. Perhaps instead of getting on your high horse it would be beneficial to understand that the people you need, to fund via tax, services for the homeless can and do leave. It's not their fault, that lies with whoever is distributing tax money to these services. So be angry at the local, state or national government. Not someone giving an honest opinion.
Have you ever lived in one? The architecture wasn't pretty, but thy have a lot of upsides too: Everyone has enough space for a family. There's a real sense of community. There's plenty of green space and playgrounds. They're also super-sturdy.

I have to admit that I really prefer soviet apartment blocks to, for example:

* massive cramming of housemates in London, New York, San Francisco, or similar areas with rent going to a landed gentry

* to being saddled with mortgage debt which takes half of my post-tax income, with that going to a financial system

* to living outside of economically-viable areas, where cheap housing might be found, but where I have a lousy job

or many of the other pathologies of the current market. The capitalist model works just fine when land is cheap or free, as it was for most of America's history. Once it's about inherited land ownership and collecting rents, it breaks down.

However, in a democracy with public housing, you'd likely end up with something much nicer than soviet-style apartment blocks. Compare British health care to soviet health care.
This is an overly simplistic complaint that leads to the argument that you should never use a 3rd party library.
“Cultural Differences”?Oh,guys. Are you serious?And why would you make a plastic bag pretend to be a wallet?Last year, the China Internet network information center (cnnic) calculated that the usage rate of mailbox in China was only 38.1%.So why don't you use WeChat?At least 900 million people in China use WeChat.Even without WeChat, there must be a phone?China has 1.3 billion mobile phone users.In addition，In China,Lost-property office won't actively contact owner commonly, because most lose property, do not have identity information, even if have, also confirm very hard is owner himself, because this is inferior to wait for the owner to come back.And with 1.4 billion people in China, of course you have to wait to find the owner.This paper is really full of holes.Luckily,now I understand how is “science” “justified”.
Java.

Oracle and Google are currently what may be the biggest tech-related legal battle of the decade. It is up to the supreme court now. To put it simply, Oracle claims that Google hijacked Java for its Android ecosystem.

There may be some other areas where they compete, particularly when it comes to cloud services, but I think Java is the big one.

Oh shit -- it was a really loud jarring sound, it must have been painful. They have recently started sending test phone alerts at the same time they perform the regular first Monday of the month noon emergency alert siren tests in Amsterdam. Maybe you should set an alarm just before then to make sure you're not listening to music!
