An eBPF overview, part 5: Tracing user processes
> Does YouTube have any incentive to “preserve” anything once it costs them more money than it brings in?

They clearly have little incentive to do so.

If there was a law that prevented websites from using technical or legal means to stop people scraping user-generated content, then I would agree that YouTube has not such obligation.

But since they make it hard for people to make archives of their content, then I think they do have a moral obligation to keep it up.
Can't speak to that specifically, but one thing I have heard in other similar cases is that the people who try the retraining programs, find that they don't work. Some people can sit in a classroom and listen to a lecture and learn something, other people learn by doing something on the job.

If we still had widespread apprenticeship as a way to learn, this would be fine. Classroom training isn't really the greatest way to learn something. But it's the way our society has doubled down on in the last generation or so, to the point that high schools shut down shop class programs and expanded AP, regarding anyone who didn't go to college as a failure.

Again, I don't know if it applies to the case you're discussing, just raising it as a possible explanation.
This sounds interesting, I wish I knew enough to critically analyze it.
> What's the energy density of current batteries and how much lighter would equivalent batteries be using this technology?

Not my area, but the best info I can find around is somewhere in the region of 200-250Wh/kg at the top end for current typical lithium ion batteries. I'm not sure if that's the type they're using.

Social media management isn't only about posting content. It's also about analyzing competition. You can build tools that process posts from competitive pages and start making correlations to draw conclusions. A lot of social media analytics shops do that.

you need to understand perturbation theory in the context of qft. that's no small feat but since it's a pretty universally studied grad core subject there's a lot of material. this book was actually suggested to me here

https://www.amazon.com/Renormalization-Methods-William-David...

two good (Gentle) senior undergrad books are

https://www.amazon.com/Student-Friendly-Quantum-Field-Theory...

https://www.amazon.com/Field-Quantization-Walter-Greiner/dp/...

and then there's always griffiths

https://www.amazon.com/Introduction-Elementary-Particles-Dav...

note that you don't need to read this cover to cover if you're not interested in actually doing calculations. you can skim.
You are absolutely right they don't talk about it in the article.
I got it from the NIST and I was thinking they talked about it but no.

Quite an impressive list of Kernel indeed.
Foregoing triggers in favor of validating data in the application layer can be dangerous. The problem is that you need to re-implement data validation on every path to the database. If you've got a single application server, and it's the only client that ever writes to the database, this might work. But as soon as you add another service with write capability, you need to re-implement the validation logic. What if you forget?

If you put the validation in the database, any application can leverage it. If you want to fail fast, you can still do validation in the application layer while relying on the DB layer as the ultimate validator.
This looks more like an automatically generated list of all releases "prior to 5.0.8". Since this vulnerability is apparently connected with net namespaces I doubt it goes all the way back to 2.0.

Edit: git blame shows this commit introducing the if statement that is touched by the patch linked by OP. It happened somewhere in the 4.2 branch. This doesn't mean that the problem was introduced exactly then, but it does show that it's relatively recent code.

What you're saying is several out of hundreds of different automotive grade screens had problems too. And one out of one non-automotive grade screen (Tesla's) also had problems. Not a large enough sample size, but things look statistically better for the automotive grade ones.

I'm using it for two weeks now, and it seems like they got it right. Great people inside with a willingness to connect plus the thoughtfully built product is the only two things that really lead to success.
For a few years I was in the same boat: dozens of items delivered without issue. Within the last year or so it's become more common to hear about counterfeit issues on HN as well as personally be confronted with them--I've had to return 4 items that were obvious fakes and a 5th item that was already opened and probably not legit.
Unfortunately, in my case, they've switched from being mostly UPS to mostly a combination of USPS and, increasingly, their own trucks. USPS is fine for smaller envelopes and packages and I even bought an extra-large mailbox to accommodate somewhat larger boxes. But USPS hates to come down my driveway (long and rough) so bigger packages often get hung off my mailbox, the mailbox door is left open, or sometimes just sent back to the post office for pickup.
Everyone I've ever met that earns big money writing software has worked with legacy or enterprise tech.

AEM and Salesforce developers make a ton of money, especially if they are good. Contract Sitecore developers also make a ton of money, and never seem to be short of work.

The scariest money I've seen was from a guy that is/was an "ActionScript developer". He made most of his money travelling across the country to work on maintaining and extensing retail systems that used Flash as an interface, and ActionScript for backend logic. He was working for a client of my employer, and we got to chatting when we were in the city for a few days. I didn't get an overall figure, but he'd made £10k that week...

It didn't sound like he enjoyed the work, but most of his skill set was actively around legacy tech - ColdFusion, Cobol, Classic ASP, etc.
I'm fine with UBI, but I don't think it fixes this kind of problem. A good job is not just a source of income (though of course it is that). It has a lot of other psychological and social impacts as well, which UBI doesn't replace.

But again, not saying it's not a good thing, just that it doesn't really solve this problem.
We love accessibility (and you should too)
I'm pulling for Walmart! I've seen the death of so many stores that I dearly miss (Sears, JC Penny, etc.). I can no longer get good hand tools or good t-shirts locally. And, the online stores are full of rip-offs and forgeries. Walmart is the last bastion of honest retail (where I can talk to a fellow human in person). I really hope they make it.
I was part of a group that took the free on-line class together a while back. It is not well-named, being not about 'well-being', rather entirely focused on 'happiness.' In addition, as the course is given at Yale, a college community enclave, the viewpoints of the participants are somewhat peculiar to young people who are still preparing to live in a society that is not all about them. Those two, three or four times the age of the college kids will find it hard to identify.
I’ve yet to encounter DB level integrity problems that aren’t solved by a well designed, normalized schema combined with proper use of transactions, PKs, FKs, unique and not null constraints, etc.

These problems probably exist, but they’re very rare. Much more rare than people THINKING they have a problem like this, hacking around it with poorly implemented application code, and ending up with data that has integrity issues, when it could have been solved well using the DB properly.
They're just a pictorial way of arranging calculations involving pretty technical stuff really. You're not expected to make sense of it without going through the (roughly grad school level physics) groundwork. I get that this can be frustrating, but maybe it's not a good idea sticking them in popsci just because they look intuitive.

I mean, they are, but only after you've learnt about the machinery behind them. For instance I wouldn't know how to convey the difference between fermionic lines and the bosonic ones without working through commutation and anticommutation relations, the gamma matrices, spinors, the different propagators and so on. Saying simply that fermions are straight lines with oriented arrows, bosons are wiggly lines and we'll draw them like this... doesn't help much when it comes to understanding what they mean, in my opinion.
Ubiquiti Networks have their Unifi product line that sells to business but since they don't charge licence fees have become quite popular with keen home users.

There's regular firmware updates and the feature set is quite standard.

Though their routers and access points are separate:
Eg: Their smallest router: https://www.ui.com/unifi-routing/usg/

Their cheap WiFi AP:
https://www.ui.com/unifi/unifi-ap-ac-pro/

To configure the network you use their controller software, can be deployed on a raspberry pi but I just run it ad hoc on my laptop when I need to change some configuration.
Depending on what you are actually trying to find out, you may also need to look into how that wealth is distributed. GDP doesn't mean much for most if 99.9% of that wealth is just owned by .01% of the population. Cost of living is also significant. Plus there are other externalities. How much use is it being rich if you can't step outside because the air is so polluted? Does the population have to work on average 80 hours a week to achieve that GDP? How much corruption is there? etc..

Show HN: Guestboard – If Slack and Facebook Events Had a Baby
Hey HN!

Guestboard (https://guestboard.co) is something we've been working on for the last year or so, and are excited to be sharing it with you all.

Guestboard keeps all your big group events under one roof, and includes a growing number of optional widgets to help your event, currently:

• A Central message board (forum)

• Shared resources (to post important links like GDocs, lineup posters, etc)

• Airbnb map

• Timeline/Schedule

• Interactive checklist (my favorite)

• Parter Deals (so you can save money on goods and services related to your specific event type)

Important note: We know, and an iOS AND Android app is currently cooking in the background. :)

------

A little backstory, for those who want to read more:

Out of personal frustration, we began with the mission of allowing WEDDING GUESTS to see who else is going, and be able to plan carpools, share flight deals, and more. (b/c weddings are stupid expensive for the guests, too)

But we quickly saw that our beta users were using it for OTHER group events that required a bit more organization rather than "just showing up"..

..events like bachelor/bachelorette parties, camping for a music festival, group vacations, and small retreats/conferences.

As a couple of 30-year-olds, we remember how FB events USED to be used - a place to invite and plan events with your real friends. But FB events has quickly become a mess of invitations from local businesses trying to drum up ticket sales.

Meetup.com didn't make sense, eventbrite.com seemed more appropriate for charging admission, and ultimately, we saw a general shift to reverting back to massive email chains or group texts..

.And we hate 20-person group texts.

There's still much to do, but really looking forward to your feedback and thoughts. Cheers!

A Bunch of Money on AWS and Some Benchmark Results
Until very recently, your ancestors didn't have too much of a choice.
I have a feeling it is too late. The train has left the station on this one.
> First, I don't understand how you're suggesting this situation arises. You're talking about a bunch of people all pulling from a branch while the only guy working on it is merrily force-pushing code and has absolutely no clue that anyone else is building work on top of it. Why in the world is there no communication on your team?

Code can be communication too. It's really nice to be able to just pull someone's branch (that they maybe mentioned in standup) without having to interrupt them to tell them you're doing it.

> Second... how is this any different from when the dev just gentle-pushes new commits instead of force-pushing?! You all will still end up having to resolve conflicts just the same when you rebase on top of their branch again... it sounds to me like what you're against is actually rebasing, only disguised as force-pushing.

When a dev gentle-pushes new commits and people merge them into their branches, it doesn't cause problems if they resolve conflicts differently, and other people who pull from their branches in turn don't have to keep re-resolving the same conflicts.

Rebase and force push are two sides of the same coin, let's not argue semantics. I say "no force pushing" rather than "no rebasing" because local rebase before you push doesn't cause problems.
Is this trolling or are you serious?

Proprietary drivers are shipped with many distributions. For example nvidia drivers are shipped with Ubuntu. If the repo drivers don't suit you, you can (just like on all other platforms) download drivers from the vendors website.

Proprietary drivers are allowed and are shipped in many distros (just like in Android), but they cannot be included in the kernel upstream (then they wouldn't be proprietary).

Every vendor is welcome and encouraged to submit their driver to the upstream linux kernel project. Some vendors do however chose not to do so, for a variety of terrible-to-mediocre reasons.
The point Bayley is making is that there is a motley crew of people of all political persuasions who think modernization in the 20th C was a disaster. The mechanization of war was the big shock. Obviously there is everything from e.g. socialist environmentalists on the left to the libertarian rejection of organized society on the right. There's a huge spectrum.

Non pre-funded pensions are absolute madness. Pension funds are going bankrupt left and right. They are built on the ridiculous premise that the fund’s investments will perform well or that the parent company will be making enough money to pay out anyway.

They should probably just switch to defined-contribution plans and abandon the pension program altogether. I imagine politics got in the way of that, and that pre-funding the pension is the compromise position.
You still get stuff through USPS? Everything I've ordered has been through AMZL, which means 100% of my orders are left at a neighbor's house, marked as delivered and then show up a few days later, or marked as lost after 5 days and refunded.

The $5 credits they give me are only good on stuff sold by Amazon, which seems to be getting slimmer. I got three things last week figuring I'd get $20 off, and it was only after I checked out that I realized none of them were by Amazon.

It's worth noting that video game LPs as a format in general have been on a downtown lately, likely because streaming (a la Twitch) has been on the rise, is more profitable, and requires substantially less post-production work. The implosion of the Something Awful forums which incentivized the creation of high production-value LPs didn't help.

I've wondered for quite some time exactly why we don't sequester carbon in this way. Is it really just "we should recycle"? Or is there another (I hate the term but perhaps more "steelmanned") argument for it?

The problem is that sendgrid is accepting email messages, just not delivering them to recipients.

So even if we add that, our users don’t know what emails to resend, which would only add to the confusion.

When a company like sendgrid has an issue, that’s fine. It is not fine to not update their status page and leave their customers out to dry.

Just so you know, Walmart is not the underdog. Walmart sells many multiples the volume that Amazon does, and to boot, most of the products sold are owned by Walmart. Amazon is merely a fee-taker on the majority of the product sales that it facilitates.
It's so odd to see Walmart getting cheered on as a plucky neighborhood underdog. They were Amazon before Amazon, using their huge scale to drive local competition out of business and relentlessly pressuring suppliers to drive down prices.

All that said I'm rooting for them too, simply because competition with Amazon is good for everyone.
