Thanks for the article! Using incense for testing seems like a good approach. And yes, the lack of difference between "taped" and "non-taped" is definitely interesting. I'm wondering if this might be in part because of your choice to use thin and small HEPA filters instead of the more common thicker and full size MERV filters. Intuitively, what matters is the product of the efficiency of the filter and the amount of air passing through the filter. It's possible that because the resistance of the small HEPA filters is so high, the unfiltered air passing around the filters generates a lower pressure in front of the filter than the non-moving air after the back is taped.

I recently built up a couple similar box fan filters, but using 20"x20"x5" MERV 15 filters bought "used" off Amazon for about $20 each. Note that the total surface area of the folded filter matters for air resistance, not just the height and width of the filter. That is, depth matters, because all else equal the folds increase the amount of filter area.

I sealed well, because I thought it would matter. I removed the back plastic grill to reduce resistance a bit more, and also added a cardboard cowling on the front of the fan, based on the research here: https://www.texairfilters.com/how-to-improve-the-efficiency-.... The idea is that with a high resistance filter on the back, in the absence of cowling you get unhelpful recirculation from the front corners of the fan, although maybe this recirculation might actually be helping reduce pressure in front of the filter in your taped example?

I haven't done any air quality measurements, but I think the system is working the way I'd expect. Noise at low speed is tolerable when in another room, but I only use higher speeds when leaving the house. I'd be interested in more details about your particulate monitor, especially if you are satisfied with it and if it's available in the US.
It isn't just about obfuscation: even if you always send money back to your own address that ends up being a round-trip on your own money as "change". And "in your address" also doesn't help the mental model here because addresses only have money by summing up all of the outputs that are spendable by the associated key, which leads to the change question in the first place (as you definitely can spend part of your money).

The analogy I would use is that Bitcoin exists in your wallet as like a bag of gold nuggets. To do a Bitcoin transactions is to take a pile of gold nuggets, melt them together, and then pour off a handful of new piles that you let cool back into nuggets. These nuggets are inherently of awkward value units as, if nothing else, the price of gold keeps changing. So you aren't going to have a set of nuggets that ever correctly maps to "price of hamburger". What you do with the resulting nuggets is up to you, but the total amount of gold in the input nuggets and the total amount of gold in the output nuggets has to be the same. This inherently will lead to most transactions involving creating an output nugget that is "change" (all the gold left over from the input nuggets that I wasn't actively intending to use).
You're right, founder effect wears off in terms of consensus-free authority, and it should. Founder effects in code style and culture last practically forever, in my experience. But with Mitchell pulling $3M/year, the top job needs leadership and consensus around what to do to save Mozilla, not resting on laurels from a couple of decades ago. (BTW Mitchell was not on founding staff @ mozilla dot org; she was on Netscape's legal team and wrote the NPL and MPL.)
And yet they didn't stop the lockdowns once it was clear the stimulus was not going to happen.

List of Top VCs Looking for Investments in United States, China and Europe
"Never go full Oracle"
I've been using Thunderbird for years probably since it was created. I was going to write a message about wishing they would invest more in Thunderbird and fix a particular bug.

As I was typing this it made me starting looking a bug I've found using it. So then I started Googling around to see if someone else found it. Looking at it, it appears it's been open for 3 years. But in the bug ticket they had steps to fix it. I now know few more menus in Thunderbird that I never considered clicking on. The bug now seem to be resolved and happier.

But then I also wish they would trim it down or at least give me the option to turn stuff off. I don't want an events and task organiser and all this stuff. I just want a mail client. I also wish their spam filter would be more consistent and stuff keeps getting through that I've flagged and is clearly spam as it's the same message I've been receiving for the last couple of months.
Dead customers aren’t that much better for the service industry.
About Mesosphere:

Mesosphere was started by Berkeley PhD interned at Google Borg. They worked on some exploratory project to expand the capabilities of Borg platform and wrote some paper.

Unfortunately, that project was on a slightly skewed direction of the technical trend. The philosophy and direction embodied in that project was neither useful inside Google, nor it matches the industry trend. But nonetheless an interesting improvement.

With the reputation of the group and relationship they decided to start a company.

And once docker is out, and kubernetrd next, in 2014 many have seen that mesos the technology is bound to irrelevance.

That prediction verified itself rather quickly, when mesosphere rebranded itself d2iq.

I don’t think dwm has them, they seem like a manual tiling thing.
There is no evidence that RHEL will be releasing a free version to replace CentOS, and the fact that others will take over a replacement OS development is already known.

My comment was focused on the confusion/exasperation at why people keep implying this is no problem, because we can just use RHEL for free, as that is not true.
I once read a convincing argument that, in some cases, American's resistance to helmets caused helmet laws to have a net negative effect on health. The author claimed that the laws caused enough of a reduction in ridership that the lost exercise outweighed the reduction in injury. I've attempted to find the paper again, but I can't seem to track it down.
The traffic in and around Lyon is fucking terrible. They really need to do something to reduce how many cars are on the road.

The thing is overall the metro is decent as is the bus service and they are always full yet there are still so many cars on the road I wonder where all the people come from tbh. There are also lots of alternative options available with Lime e-scooters and Vélo'v bikes all over the place but still what feels like a million cars!

I used to live in London so a lot of traffic isn't new to me but during peak times Lyon is a nightmare so I just avoid it as much as possible.
I read it as being difficult to go back to the same type of work they were doing before they left. Marcel's expertise was in simulations and theory. As you note it's (relatively) easy to get a job in telescope software development coming from industry, but it's much harder on the theoretical (and probably experimental) side where it's less about technical skills and more about being up-to-date on the literature and advocating for your ideas. You would have to essentially start over at the thesis stage of grad school to regain the domain knowledge and build up a body of work. You'd probably work faster than you were the first time just because of the additional knowledge and wisdom, but I doubt many professors would be willing to hire you at even a Postdoc salary without a second thesis-like investment.
Not defending RedHat here, but in practical terms doesn't this just mean switching to Rocky linux when it's time to upgrade? Presumably Rocky will have a year to prepare a migration path.
R/politics isn’t full of people calling the President Drumpft while insisting its rude to mispronounce an uncommon derivation of kamala?

I've been an OpenSuSE/Leap user for many years now and agree about the balance and stability. However there's still a pretty big gap between Leap and SLES (their enterprise distro) plus each Leap point release is only supported for 2 years (something like that).
A lot of people are coming to terms with bad air quality, even in their homes. Air purifiers are selling like hotcakes, even where wildfires aren't a concern.

One of the concerns I hope will stick after this thing is (largely) over.

Something I would love for a HNer to solve is SEO for air purifiers: basically all Google results are absolute bullshit that make it harder, not easier, to make an informed choice. Much like VPNs where it just comes down to SEO, marketing, and affiliate links.
The CPI is gamed to keep people from panicking, and to ensure that the government doesn't have to increase social security payments too much, as they're tied to official CPI numbers.

Another way inflation is "hidden" is in things like product packaging. Look at how jars of spaghetti sauce, cereal boxes, packages of coffee etc. are shrinking. You pay the same price for fewer goods.
You're missing quite a bit of context here. Brave distributed tokens to users (from our User-Growth Pool of 300M BAT) as a means of ramping-up this new support model. Users then, in turn, could send received tokens to verified creators. If they wished to send the tokens to an unverified creator, the tokens would go [back to Brave] (in a settlement wallet), where they would reside until claimed by the publisher. Meanwhile, at Brave, we would reach out to unverified creators who had a growing balance waiting.

The change we made kept the tokens on the user's device. We also introduced better UI/UX as well, with many thanks to our community for helping us spot some areas for improvement. Although I'm part of the team, I still stand in awe of those few days in December, 2018. A great, yet flawed, system was radically improved in a matter of hours with a few small (yet profound) changes. And it wouldn't have been possible without Brave's incredibly engaged community.
Oracle appears anxious to "embrace" the CentOS community. Hopefully, the "extend" and "extinguish" are not on the agenda.

why nobody use openstreetmap ?

I was always wondering why google concurrent don't use OSM, the quality is better than here and they would benefit a lot from OSM to compete against google.

I don't understand why microsoft doesn't use OSM for bing map to replace their shitty map and why facebook doesn't use OSM to display map.
This sounds like a lack of full disclosure and/or the app not placing appropriate limits.

This hardly seems like an issue with the underlying API.
When there is a desktop OS used for being work-level productive that can be used at high resolution to accomplish actual work in a manner that is cost-competitive to a multi-monitor setup.
Brave has grown every month since early beta launch. It can be done, but Firefox has lost share almost every month for a long time.

Google distributing and marketing Chrome definitely hurts Firefox, and yet Brave grows. A mystery to discuss another time.
The problem is you might end up writing strange endpoints just to satisfy a specific UI page.

For example, take a small blog, that holds several posts, each with an author.

In GraphQL, you could fetch all the posts, and all info related to the author in the same query (without any new, funny business).

In REST, if you wanted this in a single query, you'd need to define some endpoint like /post-and-authors-list that fetches all the posts and complete author information for each post, whereas most REST implementations would probably involve a small set of CRUD steps on all posts, and then several queries to fetch each author for further information as well (based on the author ID in the post).

So it's not that REST can't implement anything GraphQL wants to implement, but there is a lot more work involved, is harder to scale out with developers, etc.
That's not a take off but still a niche.
The Quest 2 is more likely to just replace other VR headsets.
Scary as heck but possible.

I implemented an HSM-based signing service for a firmware attestation system a few years ago. Authorization to sign and an audit trail of signature requests were a big deal. Something like the "plop a file in a directory" would make me weep.
Since there is still widespread doubt I wouldn't put it in the same category as the early iPhone critics or even Facebook is the next Myspace crowd.
Monetize Your Writing with Micropayments
Chrome was also bundled with Adobe's Flash installer, which is ironic because Chrome bundles its own Flash plugin. So a Firefox user wanting Flash would download Adobe's Flash installer and (if they didn't watch the installer's default settings carefully) would be switched to Chrome. If a Firefox user wanted to switch to Chrome, they would have downloaded Google's Chrome installer, not Adobe's Flash installer.

Adobe had no incentive to change this relationship because they got paid by Google twice: for bundling Chrome in Flash and bundling Flash in Chrome.
The key is `aarch64` ;)
This is very different from the slimy tactics around our privacy and data.
He's not wrong. The RAM is definitely more expensive to buy from Apple, to the point that I buy the iMac with the base 8GB and then replace with aftermarket RAM and save hundreds of dollars (approximately 15-20% of the price of the entire system).

Fortunately, servicing the iMac RAM is easy in present generations.
Man, I hope Google has a decent end game in mind here. They're rearranging a lot of stuff without adding any functionality.

If that's in service of a more sensible architecture in the future, great. But for the moment it's a lot of un-learning and re-learning without any short-term gains.
The FEDERAL government didn't do anything.

STATE and LOCAL governments did.

Why should the federal government bail out states for their actions?

And yeah I will remember all this during the next election. I was a Democrat all my life until early 2020 and now I'm done. I'll be voting against them from now on.
It looks like cells of an organism multiplying.
Ask HN: How do I go about using PostGraphile?
I'm new to the whole GraphQL environment but have a lot of experience in writing REST based micro-services where most of the business logic goes into a controller and the database layer is separate.

For a new project we've chosen PostGraphile and I've spent a few days reading the PostGraphile documentation, but to me it seems like it just exposes the CRUD APIs for your underlying Postgres database and tries to move most of the logic in the database layer. I'm have a basic idea of the modularity/plugins and extendable plugins to add more functionality to the PostGraphile app.

But where/how exactly do I write the core/business logic of the micro service?

For example, I currently have a NodeJs REST based service that:

- Has an API that fetches data from database, sends it to another micro-service for processing waits for the result and stores the returned result back in the DB.

- Has an API that fetches and aggregates data from multiple micro-services and returns to the client, without doing any database reads.

- Has an API which fetches something from ElasticSearch and DynamoDB, processes it and returns a response.

So my question is, How do I do something similar with PostGraphile?

It just feels like I'm missing a piece of the puzzle.
I left vr in 2010 because there was no commercial opportunity except video games and even that was not getting more than niche traction. If you google be headsets you'll see that the occulus is basically a redo of 20 year old tech. It's still baffling why Facebook paid so much for this.
That's not a exception; in fact it's probably the most blatant supporting evidence available for "Inflation is good for [...] anything that's meant to be used.". Computers have been undergoing borderline hyperinflation (factor of two every year-and-a-half or so) for decades, and this is extremely good for anyone who wants to use a computer.
That's a false positive every day in a normal-sized school.
This does not mean he hacked Trump!

They checked that, according to his actions, he was within the bounds of the "coordinated vulnerability disclosure". A protective legal measure for whitehat hackers.

If he wasn't, then he could be sued for "hacking" and with malicious intent.

Source of my info was a dutch article ( the hacker is also dutch): https://tweakers.net/nieuws/175822/ethisch-hacker-wordt-niet...
While I don't quite see how the safety seat alone could cause that much of a difference, I don't think it is unreasonable to see a causal relationship here. Raising a child has gotten more expensive in the US for many reasons (laws about child seats, more money needed for education, no longer socially acceptable to leave kids alone for awhile) and that certainly has an impact.
Suboptimal. The "NOT" might be covered by something, and then what remains is "THIS LEG". I would have written "NO NO NO" on one leg, and "THIS THIS THIS" on the other.

In aviation, standard phraseology is generally carefully designed such that (mosts) subsets of a phrase are distinct from the opposite phrase. For example, when ATC warns of traffic, you reply either "traffic in sight" or "negative contact". When ATC hears only half of either, they still know what you meant.
Agree with you - but I think the author of the article wants to get back in as a tenure-track professor rather than a programmer or data scientist on a scientific project. They would probably see coming back in as “staff” as an unacceptable loss of status and prestige in their field. (I think that status distinction is a terrible and stupid feature of academic research but it is very deeply-ingrained as folks are socialized in PhD programs to believe that the tenure track is the only route to happiness and academic success).

I wish more people thought like you and very much agree that academia could benefit from an influx for folks with industry experience and programming best practices!
Tune into Forests from Around the World
I was indeed talking about normie stuff like games or simple applications. Those are the reasons why I will happily be staying on Windows for the next few years.
Where I work there is a bit of overlap because some projects want the dev environment to match the final environment, and Red Hat is basically the only player in the game for prod in government. I can see this pushing some projects to pay for Red Hat for dev machines versus take the risk of having a separate dev environment.

Where that isn't a concern though, it will push devs over to Ubuntu (the only other Linux flavor I've seen around here) probably, and quickly the friction in government against non-Red Hat Linux flavors will drop. As an example of that friction, last I looked Red Hat published themselves guides and scripts to get CentOS stig'ed to the level we need here, while neither Ubuntu nor anyone else had automated it.
I still have my Nintendo virtual boy from 1996. It was discontinued and someone bought it for me for a steep discount, around $20.

Not just the block reward, Bitcoin miners also receive the sum of the fees of the transactions included on each block. The idea with the progressively diminishing block reward is that transaction fees will represent a larger share of miners profits as time passes.

This isn't related to Matlab compatibility... Matlab uses UTF-16 internally but recent versions work with UTF-8 input seamlessly (converting automatically). Octave uses UTF-8 on Linux which works well, but last time I checked has broken Unicode support on Windows.
I wonder how many people, like me, tried it on a friend's equipment and found that the motion sickness is just impossible to get past.

I had motion sickness when I tried the early first-person shooters, but got over it when I learned to keep the (non-moving) screen bounds in mind. That' just impossible in VR, and when the motion in my eyes doesn't match my vestibular system, wow, it's bad.

Sigh... some of the games were amazing.
Neat! Would you mind sharing the company you work for?
The default dmenu is very, very powerful though back when I first wanted to I could never figure out how to use the damn thing. Then I saw one of Luke Smith's videos using it [0] and all of a sudden it all clicked for me. Plus you can configure it pretty easily too so long as you can read C code [1].

If you wanna have a rofi-like interface (with it showing rows of results) you could use -l [lines] to show dmenu in vertical rows rather than in one row with many entries.

Just a PSA; your use case is very well suited to rofi and if I had that workflow I'd have a hard time translating that to dmenu.

The blame for the situation lies squarely at the feet of the state and local governments. The federal government didn't force any businesses to close. There is a huge variance between states in pandemic control measures. If businesses are still open in Florida then why should Floridians pay federal income taxes to subsidize closed businesses in California?

And states do have options for funding relief at the state level. For example they could temporarily raise income taxes on the wealthy for the duration of the pandemic. Or issue pandemic bonds.
> demand that W3C, WHATWG clear up their shit and publish formal standards

WHATWG was founded explicitly to avoid that, i.e. "let's get shit done without ceremony, and whatever comes out is the actual standard". Going back to W3C-like processes would remove the very reason for its existence. Google has been very good at leveraging this, but that's mostly because other players seem unwilling to dedicate as many resources to browser-dev as they do (even when, like in Apple's and Microsoft's case, they have more than enough money to spend).
