At my (very small) college there was an email system where you could send emails to the entire campus. It pretty quickly turned into something that felt very similar to an online forum. It was conventional to use N/T at the end of subject lines for "No Text" when the subject line was all you needed to convey your message.

Email was checked with enough frequency that it was commonly used for what we use SMS / text-messaging for today. You didn't really expect people to be near their landline phone, but you could connect with most students on campus pretty easily/rapidly with the e-mail system.

This is an era before there was cell-phone service on campus, but cell phones were still very rare anyway.

Is there a flag to disable tilde escapes, or a similar command that doesn't have this feature? The mail command is a really convenient way of sending mail in scripts.
The function will perform a printf, so nesting it in an if-else subconsciously implies it's optional.

This is a quirk of human text comprehension. In a small program, it seems arbitrary because you can see it all at once. Make the branches do more than simply printf and you can see why you want to frontload the else, rather than pick through the if/else to see what always happens.
>That whole "woke" thing will work to her advantage.

I wouldn't be so sure. That whole "woke" thing is turning on white women and gay men rather quickly. Granted it's mostly middle-aged white women up to now, but Elizabeth Holmes has become a symbol of some excesses that are unpopular all over.

The latest firmware update for the Quest 2 (v33 [1]) brought "Link sharpening" which improves text clarity when connecting to your PC through Air Link (wirelessly) or Link (via USB). I tested before and after the update. Before the resolution wasn't quite there for coding etc., but I could definitely work with the post-update resolution.

As an aside, a handy cheap way to get more screens in VR with Oculus Link is to insert a headless HDMI plug into your video card. This also works for creating new screens in VR using Immersed although they claim that the virtual screens (paid feature) work better.

Show HN: Live MBTA Map (Boston T)
Hi HN! I wanted a way to visualize the MBTA system as a whole, so I hacked this together over the weekend.

It shows the current position of each bus, train, and subway, including a little tail behind each vehicle to show where it's been.

There are plenty of rider-focused experiences built around this data but I'm more interested in the visual aspect of being able to look at the whole thing at once. It's probably not a very practical tool for riders!

>and a top-down change driven by politicians/ministers needs to happen.

I'm not sure if that is politically possible. The police unions start complaining when politicians start to do something (see when they turned their back on DeBlasio in front of news cameras). I'm not sure if it's fixable without repercussions on the offending officers or the union rather than the taxpayers. There is zero or near zero repercussions of the officers, the chain of command or the union for malfeasance. Of course they are going to act how they act, they're humans. The worst part is the bad officers often corrupt the good ones, or make them quit, so over time there's just the bad.
From my experience with ShaderGif, which had some success (144 points): https://news.ycombinator.com/item?id=18666146 It's still online, but I'm thinking of turning it off every now and then.

The show HN did bring a big traffic spike for maybe a week, which brought a lot of dopamine. At this point I thought that I got the ball rolling, but the traffic faded away. After this, promoting the project became more difficult because every other channel brings much less traffic than what you see during the Show HN.

Maybe there is always something like a post-Show-HN depression, either because you got no upvote or because the traffic spike fades away.

My team and I have been re-thinking payments integrations
Hi everyone, my name is Paul and last year, a colleague and I left our positions at PayPal to found primer.io.

For my part, Primer was a response to the ever-increasing technical complexity around managing and integrating multiple payments services, and other APIs from across the web as part of a payment lifecycle.

I'm most excited about how we've tackled the developer experience around integrating payments, and future-proofing this regardless of how complex your payments flows become. And - we've managed to achieve this through a unified payment lifecycle so you only have to reason about payments once.

Happy to answer any questions you might have, and how we're thinking about scaling this in the future - or facilitating other complex use-cases :)

Show HN: pocket-sockets is a small TCP/WebSockets lib written in TypeScript
I made this nice little client/server socket lib which has the same interface both for TCP sockets and WebSockets. Free to use, MIT licensed.

You all know that browsers require WebSockets but when doing server to server communication regular TCP sockets are leaner and faster.

With pocket-sockets you can switch the underlying sockets as you need but use the same interface for both TCP and WebSockets.

Small, neat and few dependencies. Written in TypeScript with a bunch of tests to it :)

It also supports SSL/TLS encryption.

Although... ironically he is probably one of the more influential HN posters. Now, profitable, I dunno, do you really mean "conform [in order] to profit", does "influence" just mean "exploit" [in the economic sense. mostly] now?

Can we conceive of someone who would rather not conform and in fact would rather not exploit?
> people with more woke attitudes

This is extremely broad and it feels like a bit of a strawman - a classic feminist issue I've heard is how office chairs are often designed more for the average height of a man, therefore subtly excluding women from the workspace.

"people with more woke attitudes" would absolutely be on board with measures such as ensuring Asian people get the eye care they need (I suspect).

Unnecessary is very subjective. Something unnecessary for one team member may be crucial to another. One might say that the cost of specialization and focus is a growing amount of time not spent on one's area of specialization and focus.

Communication overhead increases as the number of people increases. Due to combinatorial explosion, the number of different communication channels increases rapidly with the number of people.[3] Everyone working on the same task needs to keep in sync, so as more people are added they spend more time trying to find out what everyone else is doing.

The data is sent from the advertiser to the ad platform, not from the publisher to the ad platform. The advertiser is incentivized to send accurate data for both performance optimization and for campaign measurement purposes.

Ad fraud is a real problem in the ecosystem, but the server-side APIs are actually more secure. You have a private signed backend endpoint rather than public JS that can be injected anywhere and fed fake data by a malicious party.
To summarize:

They defined these blood lead levels:

* "detectable": ≥1.0 μg/dL

* "elevated": ≥5.0 μg/dL

They found that:

* 50.5% had "detectable" levels (50.4%-50.6% for the 95% CI).

* 1.9% had "elevated" levels (1.8%-1.9% for the 95% CI [wait, how is the reported amount the same as the upper limit of the CI?]).

The paper does start out saying:

> No safe level of exposure to lead has been identified.

Which I believe to be true, though it's not the same as "no level of exposure to lead is safe". I would be interested in what levels are known to be unsafe. Is 1.0 μg/dL known to be unsafe, or just not known to be safe?

It's pretty clear we should be working to reduce lead exposure, especially in children, but it's also true that "detectable amounts" and "harmful" aren't the same thing. The former clearly varies with our technology and the other remains constant (and isn't, afaik, known to be 0).

This is a little bit above your quoted paragraph
In the US at least, were it structured as an infrastructure project on a city by city basis, it would actually be extremely possible to strip out lead pipes and replace them with something modern.

The problem is that pipe ownership in a domestic home is the property of the homeowner, and there's no political will to do that kind of massive wealth transfer from the public coffers to the improved infrastructure of millions of individual properties. But while it wouldn't be inexpensive, it's on par with other expenditures the federal government makes for federal projects.
Your English is otherwise excellent, but "used to have" implies that you had an object/thing for a period of time in the past, and don't any more. "I used to have a hovercraft".

It's the exact same flaw as cash. If you mess up and send it to the wrong person in the mail or set it on fire, there is absolutely no recourse, unless there's someone to sue maybe.

As long as you understand that I don't see the problem. I use cash a lot myself. Of course, we basically did invent the entire banking system to get away from the many downsides of literally lugging bags of gold around, like theft and loss without recourse.
Yeah.

It's unfortunate that alongside this incredibly important detail the article carries a bunch of highly judgemental wording that encourages people to incorrectly interpret "use" not as "cycle through" but as "remove from water supply and banish to a superfund site."

The rest of the comment section is guilty of this too.

I fully appreciate the need for independent verification, but assuming the worst is not that, and it actually leads to bad incentives in the same way as assuming the best (or refusing to think about it at all) leads to bad incentives.
I will say that, at least in the “woke” circles I notice, there is plenty of discussion about how medical knowledge is too centered around the white male. Finding studies that dig into the way race-specific biology should change medical treatment and risk factors is hard, and finding doctors who acknowledge those studies in how they think about patients is even harder.

The "ping" attribute is available to all sites and many content blocking extensions (including ad blockers) block these pings. This isn't changing with Manifest V3: extensions will still be able to block them.

Note that on Firefox and other browsers that do not support "ping", Google Search still tracks which links you click on, but it uses URL rewriting. There are also extensions that block this.

> You're just making things up. People love talking about intermittence of renewables

My comment has nothing to do with intermittence. It has to do with speed of transition. If you do not invest in oil & gas, supplies decrease. Because oil & gas production requires constant exploration and development in order to be productive. Because of coronavirus O&G companies did not invest in developing existing assets and exploring new ones. This was obviously going to happen last year (I traded on the expectation of it).

> Yet nowadays, when fossil fuels fail, they blame the renewables.

I literally did the exact opposite in my first sentence.

> I am honestly tired of the hypocrisy.

I'm not anti-renewables. I think they have a place in the future energy-mix. It's obvious that eventually oil and gas will run out.

> Without the renewables in Germany this fossil fuel crisis would be much worse.

If we're going to do counterfactuals we have to include the one where because Germany didn't have renewables its politicians invested more in a secure, stable supply of oil & gas.

This is not about obviousness. You can write the same expression lots of different ways, which are all obvious. This is still a question about testable paths and code hygiene.

Nesting the same function call in both branches of if/else unintentionally obscures that it's not a conditional printf call.

If you're going to write:

printf(a == b ? "equal" : "not");

you don't need the function at all, completely missing the point.

Automatic memory management in RonDB
After 5 years of development all steps in the new memory management architecture in RonDB is completed. This has been introduced in 4 steps and now the final step is completed. Thus it is a good time to describe the architecture and how it works.

The original architecture was using fixed size memory structures that was very fast, but not so flexible. We have worked hard during this transformation to retain the performance while adding a much more flexible memory architecture.

This type of automatic memory management is normally only found in expensive closed source DBMSs. Now RonDB brings this type of automatic memory management to open source DBMSs as well.
13: its curious how long production problems can be tolerated/ignored. My son just quit a job where he got moved to a group of 12 that fought a certain fire whenever it occurred (multiple times daily). Had been going on for years.

Action was initiated by an email on a certain account from the field. He immediately set up a notification for this email - something nobody else in the group had done. On the first notification he waited to see how long it took for the group to respond - almost an hour before anyone noticed. Then they went into action and hand-edited database entries to 'fix' the issue. And went back to reading comic books or whatever.

So he looked into the problem, found the root cause, submit a change order to be tested and deployed. And put 12 people out of a job his first week there.

He quit shortly after. It was not a culture he had any interest in learning any more about. It's astonishing how many of these 'Dilbert' groups exist inside large organizations.
