I watched it recently because it was some podcasters favorite movie. I like good romcoms but sadly I personally found Love Actually to be horrible and was surprised by the high ratings. There is no "love" in "Love Actually" there is only lust except maybe the old rock star. Every pictured relationship is extremely superficial. I'm also surprised the sexual harassment issues in two of the stories are not called out more. Then again, 400k people rated it 7.6 which is high so clearly they all see something I don't. There are plenty of romcoms I like though. ... though if you go read the user reviews on IMDB, after the first page or so they get pretty negative, so I'm not alone in not getting it.
When is music in shows or movies manipulation, and what counts as genuine use? If one of the characters plays an instrument in the show?

I'd say music is always manipulation as it's always triggering emotions in some way. Unless it's some genre or band you absolutely hate. But even then it's triggering emotions, just probably not the intended ones. :-)
Ask HN: Will you consider CentOS 8 Stream?
When I first read the responses to the project's reorganization, I was disappointed like many of you. Speculating IBM to be behind all of it seemed a logical gut reaction.

But thinking about it, it started to make sense to me. Red Hat always organizes upstream communities. The freely available, unbranded (as in, not Red Hat-branded) software is always ahead in terms of features, and possibly lagging in stability: oVirt, Ansible, Foreman, and many others.

So in this way, CentOS was always an exception. Not driving innovation, but taking tremendous resources to keep decade-long promises.

Now I understand that CentOS was not launched but acquired by Red Hat, and in turn how they broke a serious LTS commitment shortly after release. And sure, the trust is damaged not necessarily because they withdrew a free project, but because how they did it.

But for those of us who manage smaller deployments, it seems like CentOS Stream could be a very nice middle ground between new features introduced in Fedora and the stability of RHEL. Back when CentOS 8 was awaiting release, my team decided to install Fedora on our (less than 5) servers, but now eyeing Stream as a viable alternative.
Be very careful - even if things are compatible, in my experience some things do not perform as well in CockroachDB which seems a bit counter intuitive but can be very true... We had problems making date range queries fast with tiny amounts of data, for example.

I would seriously consider if you need CockroachDB - if you need that level of scaling you should also consider Cassandra (or Cassandra like) solutions as they will scale better but you will have to architect your app to think in this way (i.e. your app generates the views of the data it needs).

If you don't need to scale yet use Postgres. Every piece of complexity has a cost and Cockroach while incredibly clever adds complexity that you might not understand or desire to manage over time. A nice interface won't help you when replication between clusters breaks in production.

Doing a thing because that's how it's always been done sounds like stagnation to me. The purpose of meter is to make it flow well when you say it out loud. And rhyming, idk, it has a pleasant quality to it too. But if you don't care for these things, then don't force yourself into it.

Consider cooking. Certainly cooking has a lot of "tropes". And that's because they are tried and true methods of making it taste well. In addition I think you will all recognize the "Appetizer, Main, Dessert". Is that a method of "manipulating you" into enjoying your food? Yes it is! And that's why we love it.

I’m not going to continue doing your laptop buyers homework for you, but I just checked the T480 spec sheet[0]:

So definitely not way ahead either, actually behind the first two on one of your criteria.

Look, it’s obvious you have a bias against Apple, likely even a justified one. I have reasons I hate them too. But can we please not post baseless claims like you seem to be doing? I personally feel folks doing that are contributing to the huge backwards slide of content quality on the internet. If you want to say you prefer non-Apple laptops, that’s entirely fine, just don’t try to justify your decision with arbitrary ratios without actually running the numbers and seeing if Apple really is “far behind the competition” on those arbitrary criteria.

I'd argue that they do, and that will become more and more true. Things as simple as an Excel file, or writing simple email filtering rules may expose you to _some_ programming.

As a side note - I believe this is going to be more and more true, especially among knowledge workers - I'm somewhat bullish on UiPath's low-code app platform [+]. As programmers we understand well the benefits (and pitfalls) of automating our menial tasks, if you can lower the bar so that most people (like assistant managers, receptionists, call center operators etc) can do that - you suddenly start exposing much wider audiences to programming. It's a tough problem but I believe RPA might just be the right foundation to enable that sort of thing.

- Bayesian Neural ODEs with Stochastic Langevin Gradient Descent (https://diffeqflux.sciml.ai/dev/examples/BayesianNODE_SGLD/)

- General usage of the differential equation solvers (ODEs, SDEs, DDEs) in the Turing probabilistic programming language (https://turing.ml/dev/tutorials/10-bayesiandiffeq/)

- More demonstrations of ODEs, SDEs, and DDEs estimated by Turing + DifferentialEquations.jl in a way that you can swap in neural networks (https://github.com/TuringLang/TuringTutorials/blob/master/10...)

Our focus is more on the model discovery and scientific machine learning aspects, but we did throw an MNIST portion in there for good measure. The results are still early but everything is usable today.

Global chip shortage threatens production of laptops, smartphones and more
Oh, but you do! Not all till shortages are due to theft, and not all theft at cash registers happens in ways that the till is off. Folks do lots of tricks to try to make sure the till count is correct: For example, scanning cheap items, not scanning things, charging more than the register total (and pocketing the rest)... and so on. Occasionally, it gets you out of being in trouble (some dude took goods and walked out of a place I worked at, after I scanned it but obviously before he paid, for example). Most places have variance built in as well - no one is perfect, after all. Some are stricter than others, and many places share the till between people because it takes more labor to do otherwise.

The till not being able to catch everything is a reason for the cameras, and the reason they aren't just around the till. (cosmetics often have cameras as do receiving areas). Bag checks are really common as well. Sure, you could just have an inventory management system, but again, these aren't foolproof nor do these systems give you a clue about who is stealing or if it is a simple mistake.

Any MERV8 or higher filter will work.

You don't need a HEPA filter. HEPA is only useful when you can only pass the air through the filter once, like in hospitals. A home air filter can push the air through the filter several times, so an MERV8 is just as good as a HEPA and lasts longer.

I used a DIY filter to remove wildfire smoke from my apartment. It's just a 12"x12" MERV8 filter taped to the front of a small fan. It worked well. I periodically opened my windows to exchange the stuffy air with fresh+smokey air. After closing the windows, the filter took about 30 minutes to remove all of the smoke inside.

Paxos raises $142M in Series C funding
I build one during the forest fires earlier in the year, I bought a box fan and 6 Merv 14 furnace filters.

My best idea was cutting out the front and back wall of the box the filters came with and squishing the fan between two.

It worked well enough with the 50cm fan that it could make a 10x8m room pleasant in 10 minutes. The only improvement I would make would be buying a lower rated filter for the intake since it got clogged up with a lot of large particles that were kicked up by the fan.

I was planning a big build with an impeller fan, but there is something to be said for a solution so stupid that I can rebuild it in 5 minutes with $50 in parts.

Sliding friction is an issue with efficiency, I suspect. The flat sides of the rotor are holding back hot, compressed, abrasive gas. That means the faces need to be very flat and very rigid.

Unlike the face of an engine block, you can't get away with a gasket to mask imperfections. You need a hard, smooth bearing surface. That means expensive materials, which makes them even harder to flatten. Then you need the actual sealing elements, and they'll be at the worst spots possible- far away from the shaft. The sealed edge is in fact the fastest-moving part of the engine.

Bearing surfaces are rated on their PV- pressure times velocity. Both pressure and velocity create heat, and the life of a bearing surface is very roughly inversely proportional to the 4th power of the PV it's run at. Naturally, you want to put bearings as close to the shaft as possible.

> They seem to think the apex seal wear issue will be better with the apex seals stationary.

They're almost certainly right, although the actual details of implementing the seal are very complicated. They have to seal the corners as well as the sliding edge, so you need multi-part seals that are cut so that spring tension pushes them all outwards, and they still have to seal against each other[1]. They also need to be pressed sideways into their groove and kept from being dragged diagonally.

However, normal Wankels burn oil to keep the seals lubricated. Since these are stationary, they can be fed from oil in the crankcase. They can also be fenced in with scraper rings like a normal piston has, which keeps oil on the bearing surface and prevents it from being burnt off. Normal Wankel rotors lift off too much to keep the oil contained.

> I also wonder if they have a good solution to having more than two rotors? Mazda made a 3-rotor but due to the way the engine fits together the eccentric shaft had to be in two pieces that bolt together.

IIRC they'll have pretty bad second-order vibration, but either way the exhaust/intake is in the way to a significant degree.

I also don't mind being tracked. If I must see ads, then I rather see relevant ads. There is nothing bad in this.

I don't understand the facebook/google bashing here. It's not as you could advertise on apple for something against apple.

It should also be clear to you what game Apple is playing here. Their end game is to do the tracking themselves and then they will slowly introduce and sell ads themselves. Their marketing department will then call it "privacy ads", but it's going to be the same as todays google/fb ads.

I think you might interpret the word more harshly than I intend it to be. Something that worked before Big Sur is not working in Big Sur. It's broken. That's all there is to it for me as an end user. Of course there is a difference in reasons for things breaking, and I'm not denying that Apple might have "improved" Preview.app when you judge it by how well it adheres to a PDF spec. But it still "broke" a very common and normal workflow by doing so, and I would at least expect them to acknowledge that. If they decide breaking this is worth it, that's absolutely fine with me. But I don't think they are even aware of it, and that is not something I'm willing accept from a company with the reach and resources of Apple.
