One thing I have always failed to understand about self-driving tech -- what's the motivation for each car to do its own self-driving computation in busy metropolitan areas?

Are there technologies that integrate with some kind of existing infrastructure like beacons, etc. that would just tell the car where the streets are? If not, why not?
Really? Almost the entirety of where I see this is people recording and re-uploading content from tik tok onto Twitter. It’s certainly a distinct communication culture. I mean “Instagram dance” was never a thing the way “Tik tok dance” is a thing.
I used a modified version of Tufte.css (forked years ago) for my website[0]. I love the way it works for the longish posts I wanted to make but Tufte's ideas are not without their problems when converted into a web page.

The design really works best in landscape mode. Portrait "works" but the sidenotes interact with the main text and each other in annoying ways. This sometimes makes writing documents harder than it should be since I have to test the output in both Landscape and Portrait to make sure it doesn't look terrible.

This somewhat defeats my goal of having a nice clean markdown->styled html workflow. I often have to make small changes to get things looking OK.

That said, I am very happy with the overall look and functionality of the style.

I picture these being used around hospitals and nursing homes for general fetching and returning of things. i.e. linens, telephones, keeping patient's belongings in their own room (this was a nightmare for my grandma in the alzheimer's ward) and other things that would allow nurses and porters to be more effective

Yes, Canada has a carbon tax but no carbon tariff, with the obvious incentive to move economic activity to dirtier countries.
this reads like astroturfing
I think it's a bit different because the games that were put on your childhood computers are designed specifically for children to learn early years skills (mathematics, history, etc.) while something like "This War of Mine" is developed for a wide audience and has now been co-opted into an education system to teach children about refugees, etc.
None of these things are incompatible with a VM running SEV. In fact, since many of Google's managed services themselves use Compute Engine, they may already support Confidential VM's running SEV.

Perhaps I simply don’t consider the Hispanic concentration camps, private credit scores that still gate hiring, access to healthcare (via hiring) and renting and apartment, and surveillance panopticon powered by Google, better?

how exactly is it challenging it. Spanner is too expensive.
Yeah, actually I wish HN would make me laugh and dance, this comment makes tiktok sound pretty good!
Bootcamps might be a decent option. You could also apply to jobs you want and see what they say. Chances are, many of them will want a special piece of paper - a degree. So you should look into that too.
Yeah especially if your company has more than one location - for redunancy

Yep, I also remember reading and analysing the Hiob story.
I really liked causal.app when I tried it briefly. Nice way to build interactive dashboards from spreadsheets, with a range of outcomes - and they have some excellent templates
This is a lazy justification with little substance that applies just as much to the users and content and voting structure of this forum. The alternative is not talking to anyone or not choosing who we talk to.
I do get your sentiment but it's not really addressing what I believe the GPs point to be, which is redundant framework bloat for personal blogs. Take the sites I personally run, one of them is written in markdown and "compiled" to HTML using `pandoc` (a CLI document conversion tool) and then it's pushed to S3. Some of the others are run on dynamic CMSs and have modern frameworks used to "help speed up development". But you know which site was actually the quickest to develop? It's also the site which which loads the quickest, costs the least to host and requires the least upkeep -- it's the one which doesn't use any frameworks at all, just a few lines of hand-crafted CSS. It doesn't even have any Javascript.

I'm not saying everyone has to go that minimal but my (and I suspect the GPs) point is that people can get carried away when designing their personal blogs, and in fact sites in general, and miss the point of what their site is actually trying to achieve in the process. If someone feels they need a loading screen to serve a static blog then I suspect they've probably fallen into that trap themselves.
Well, let's see: On the one hand, the Marine pilot did something that in different circumstances he would have been required to do (low-level flight, e.g., in combat and/or in training for combat). Moreover, there was considerable doubt whether they had been provided with up-to-date maps showing what areas were off-limits. They were acquitted of the manslaughter charges — but they were later cashiered for destroying evidence, i.e., a videotape of the accident [2], because for military officers, integrity is supposed to be at the top of the list of required personal qualities.

Oh, and let's not forget that the pilot and NFO had previously had good records (AFAIK) and for many years had been putting their asses on the line for their country every single time they took off in a plane. (There's an old joke that when you join the U.S. military, you sign a blank check made out to the People of the United States of America, payable in any amount up to and including your life.)

On the other hand, we have the civilian "yardbird" who, wanting to go home, intentionally started a fire that led to the essentially-total loss [3] of a major national military asset. "Rear Adm. Richard Breckenridge, a submarine group commander, said the ship's extensive damage had ripple effects around the Navy, delaying repairs on other vessels and leading to longer deployments for thousands of sailors." [4]

If you don't see why that might lead to very-different sentences for the two cases, I'm afraid we don't have much else to discuss on that point.

Ask HN: Best chat software for an online university class?
College professor here. Owing to the pandemic, I've just pulled the plug on a class I'm teaching in elementary number theory, and moved it to online delivery.

I am hoping to get some lively interaction going on between classes, and I intend to use some sort of chat software for this. Officially, my university uses Blackboard for this, but as the currently #1-ranked entry in HN's "best comments" list explains, "the user interface is designed as if the programmers were incentivized to maximize the number of clicks required to get anywhere" and "it has the responsiveness of continental drift". No wonder my students barely used it when I set up a chatroom last Spring.

I'll therefore be looking for something else: Slack, Zulip, Discord are options I've heard of and am at least vaguely familiar with, and I'm also open to trying something new.

Any recommendations for what software to choose and how to use it effectively?
> all which can add to an employees distraction load and decrease productivity when compared to a more basic code-host.

Is a bit naive to think those features are the ones distracting the employees, when if you watch a developer at work 98% of the time-wasters are the strongly attractive ones: YouTube, Instagram, etc.
This made me laugh. Thanks, I really needed that.
Hm, juxtapose a bunch of such responses with something in the spirit of Pollock's ‘burnt spaghetti’ but in cyberpunkish tones—and you could have a pretty topical display for these days. If not very subtle.

Intel actually had a similar tech without the RAM encryption some time ago, called TXT.

TXT never really took off. There were a few problems, but, I don't think SEV has actually solved these problems, beyond the lack of the memory encryption.

One is that the hypervisor is ... well it's still a hypervisor. It can play a lot of games on the operating system, and hardware is limited in what it can do to stop that. TXT's solution was to "measure" the hypervisor, so you could audit it. That doesn't work for google/aws/azure who all use proprietary hypervisors, so you need to place a lot of trust in your chip and kernel that they can resist arbitrary malicious behaviour by the most privileged piece of software on the system - one that controls all hardware access. That's very difficult. For instance, the hypervisor controls access to the system clock.

Another is that it was very hard to make the operating system secure. Heartbleed being just one example of what can go wrong. So the trusted computing community concluded around this time that placing an entire operating system into your 'trusted computing base' doesn't really work. It's trying to run before you can walk. If you can't make the operating system reliably secure against remote attackers then trying to make it secure against the far harder adversary of someone who controls your hardware stack seems futile.

That's why Intel's equivalent isn't transparent. It's not very opaque, it's basically like loading a shared library and the library gets encrypted RAM. But when you try to write an enclave that's really secure, you realise that there's a lot the host machine can do to make a mess of things. I don't think that changes much if it's "just" the hypervisor that's malicious instead of the hypervisor and kernel. The solutions end up looking the same - you want to minimise your attack surface, you need to think carefully about clocks and time sequencing, side channel attacks, etc.
It's similar to how we don't teach kids basic accounting or personal finance in high school and they graduate and find themselves in mountains of high interest cc debit and making bad financial decisions after another, because they can learn it on their own when they're adults.
Actually the events themselves are only part of the outage. There has to be time for the link to come back up (not instantaneous). If the disruption is minor this might be a few hundred ms. However this is still long enough on OTN networks to trigger protection switching (scale is 100us). This causes traffic to be rerouted (disruptive). Additionally during a storm, it’s not uncommon for there to multiple lightning strikes in the same region. When I say same region, think the length of the state of Florida.

BTW, Florida was where this phenomenon was first observed; every summer there would be multiple outages.

The large amount of traffic on the fiber can be an issue and cause congestion and other problems (25T is a lot of traffic). Furthermore service and equipment providers have SLAs and outages can cost each money.

Sorry to hear that you felt forced to read a set of slides on the matter.
This is reductionist, I am not the first to fall in line to support github here, but lets expand on what github is instead of assuming.

Github is, primarily, managed source code hosting- but it has more components, so lets break them out:

1: Source code hosting

2: Web view

3: Issue tracking

4: Project management tracking

5: Search

6: Authentication and identity (oauth2 and "applications")

7: Documentation rendering

8: Web hosting (a-la github pages)

9: CI pipeline (github actions)

SVN replaces point 1, and poorly. How many hours do you need to manage an SVN server? Very few I would wager but it at least behooves to ask the question. And it certainly behooves to understand that you're not replacing 1:1; you're replacing many things with one, and managing the above yourself can be done cheaper, but poorer, so that "poor" imitation could cost more time for using it too.

It's a very nuanced topic but an interesting one, and reductionist questions like this are not helpful.
Japanese Squiers are great. My uncle, who is a fantastic guitarist and has all kinds of amazing guitars, often still gigs on his late 80s Squier Strat.
The article and its associated paper did not really engage me. Perhaps I am missing something.

However, I was reminded of something that I learned when taking drama lessons as a teenager, and which I have used as a teacher. Our attention of an object (such as another human) oscillates from eye to eye. However, it is biased to one eye. Generally this is the one on the opposite site to our writing norm (i.e. left handed = right eyed). If you really want to hold a scene when being filmed, look unwaveringly out of the eye that is nearest the camera. It will feel unnatural, but look dam cool on the screen. Look carefully... you can see Laurence Olivier and others doing precisely this.

As a teacher I use it in class to hold attention. But it’s best effect is on the screen.
Not sure if you're aware of the fact of what was going on in Hong Kong and the loss of its autonomous status due to the national security law. Facebook and TikTok are no different to privacy, but TikTok can give all of that data and the CCP can access it. But of course it doesn't matter to you because 'its pretty harmless'.

For Hong Kong citizens, it's much worse. They are being identified and arrested in the hundreds as the Chinese government has access to this data to find anyone insulting or ridiculing them. That's very totalitarian to me.
Being dismissed from the ER while having serious conditions that they overlooked is an awful experience. I wanted to let you know that my wife and I can sympathize with you and your SO.
It looks like they may also be brigading this post. Two downvotes pretty quickly on my comment. Maybe I'm out-of-touch with Hacker News norms, but I didn't think I said anything that warrants downvotes.

Edit to add: I don't make this post to complain about downvotes. The point was the potential brigading, since we're talking negatively about the Chinese state.
Wow, that's an awful way of getting de-platformed
It's paper. It just happens to be a cotton/linen long-fibre pulp blend rather than, say, wood pulp. That's how most paper was made from the origins of the stuff, in the West at least; wood pulp and so forth are relatively new in the grand scheme of things.
Lots of room/house mates, possibly to the point of illegality (that is, beyond the legal occupancy limit).
Yes, they get rid of content from "ugly, poor or disabled users" so you have an even "better" experience. So not only is it Chinese spyware, it is an awful company too.

Power cuts every month doesn't seem very normal to me. I had a home server running for a few years without UPS, and at one point it had over 2 years of uptime.
Is there any reason to think that positivity will continue to hold? Or is TikTok just getting its grace period before griefers, trolls, and paranoiacs move in?

If the Chinese government is going to aggressively moderate TikTok to keep that out... uh, cool, I guess. I'd be happy to see some popular entertainment that doesn't devolve into a screaming match. But it's a lot of work, and reduces audience (i.e. revenue).
That's where SRI comes into play. And even if SRI isn't used, having a separate subdomain still makes it impossible to surreptitiously MITM host traffic, since attacking the site via scripts served by CDN would leave behind evidence.
I know a company which I will not name, that was passing source-code around with a USB drive.

Their version of an SVN lock was basically 'who has the USB stick right now'. And while this is an absurd and extreme example (and a true one, crucially) you can't deny that github would have saved those developers countless hours.

Maybe even enough hours to pay a person full time to manage something on-site: but that's why this topic (and the OP's site) is interesting, how do we quantify it?
> But that makes no sense because you're trying to defend yourself against Google.

If you're using a cloud provider, you ultimately have to trust that provider is doing what they claim. After all, you have to use their management control plane to configure SEV, and that control plane could always be lying about whether SEV is actually working.

So SEV isn't intended as a defense against Google as an organization. What it can do, is provide a layer of defense against rogue hardware administrators, as well as other tenants that might be sharing the physical machine.
It's cheaper to buy a self-driving car than to augment every road the customer might want to drive on.

Maybe if we were immediately jumping to 50% self-driving adoption it would be easier to make smart roads, but that's not the world we're living in yet.
I don’t see what excludes building an application server with a systems programming language. Business applications have maintenance costs that the ORM backloads; it’s not like all businesses need to do this. There’s nothing inherently “business logic friendly” about an ORM.
Ask HN: What are some good sites or blogs about the mechanics behind trading?
I'm looking for stuff about the technical side of things (I don't mean the tech they employ, but more about HOW they do it).

Things like in-depth analysis of methods, quants, maths involved and such.

I hope I'm not being too ambiguous but I'm not looking to find the latest stocks to make money from or anything, more about the mechanics and maths of trading... I suppose I'm not sure exactly what I want, just that I don't want to get stock tips or any of that.

Does that make sense?
> Not to start a flame war over book choice but forcing kids to read the Bible, Homer's Iliad, and Shakespeare are probably what is causing such marked disinterest in the first place. There are so many interesting and valuable works of writing, fiction and non-fiction, that can captivate and entertain modern children that aren't unapproachable tomes translated from ancient, dead languages, or written in Iambic Pentameter.

The idea of mandatory novels isn't to entertain and captivate. It is to bring young people into the culture that they will live in, and it's done by studying the culture's roots. Having said that, I felt like a TON of that stuff just flew over my head when I was in school - I mean, literary experts discuss the meaning of for example Mickiewicz's work to this day, and I, a child/teen with no frame of reference, am supposed to get some of it? It would require highly talented teachers to pull this off.
This must be some nonstandard definition of transmitting.
Hence, by law.

A legal mandate avoids the race-to-the-bottom trend.
My point is that you shouldn't shout at people taking steps. You should encourage them to take more steps.
You could probably freelance without a degree. But most of the positions I see, even for rote website design, the company tends to require a degree. I'm in the eastern US, so this could vary elsewhere.

That doesn't work; the problem is not that it specifies a font but that the CSS specifies "font-family: monospace"; I just verified that setting gfx.downloadable_fonts.enabled = false doesn't change anything. (Deleting that from the CSS works, as does using Reader Mode.)

But regardless, deliberately setting prose to be monospace is a poor styling choice, and it probably is a choice because that's usually to give the typewriter aesthetic.
We're going to need a new system.

The profit motive of corporations is directly in conflict with the duty to social good. As we proceed into an automated future, our labor protections are pricing humans out of the market. A great deal of unnecessary evil and pain worldwide results from this conflict.

At the scale of corporations such as Verizon, even a cost efficiency of one cent per transaction can translate into tens or hundreds of millions of dollars on the bottom line. Simple state machines with rigorously defined transitions are very efficient. Creatively handling exceptions and undefined states is a capability of human employees, and it's often very inefficient to do so. A million automated transactions could occur for every one bespoke transaction requiring ingenious human attention. Ideally, corporations would prefer not to hire people at all, but where does that leave us as a society?
> ... machine ... has ... events that can kill it ...

So if the robot blows a $0.03 (i.e., 3 cents) electrolytic cap [0], that's an independent event type that "killed" the machine? Just trying to get a sense of how you define "machine kill" (and as I said I mentioned a big caveat of right-to-repair laws).

I would say that non-fiction books, giving a view on the past errors in the human history, should be considered very important titles. "A World Apart" by Herling Grudzinski was the most important book on the lecture list when I was in high school. I'm happy to see that "Conversations with an Executioner" has been included in the list recently. Humanity tends to forget the bad times far too easily...

Other than that, I believe it is important to know the roots of the modern culture and society, and classic literature from authors like Dostoevsky, Mickiewicz, Conrad, Prus, Bulgakov, Shakespeare, Orwell, Hemmingway, Schulz, Twain, Huxley and many many others. I've met all of them in my school years and I'm thankful for that.
The FCC definition of broadcasting (per Part 97) is "Transmissions intended for reception by the general public, either direct or relayed."

This is not allowed on ham bands, as these are not frequencies for general public use. Broadcasting implies one-way communication only. Hams expect to receive responses to their transmissions, thus the distinction.
