Okay. This is decent. I do like the idea of "fancy multiplications" because I do think you should understand convolution as well as you understand multiplication.

But I still feel like this kinda obscures and confuses the origin of the reversal.*

If you don't understand the convolution formula instinctively, read this comment enough times till you do.

The point is this.

-We have a function originBangSound(t) that maps the effect at (t) of an impulse or "bang" coming from the origin (t=0).

-We have a function bangWeights(t), which measures the distribution of impulses or "bangs" over time.

-The question is: how do we get the total allBangSounds(t)?

Simple: We make every point in time the origin, and add all the results together. Let's call (tau) the current origin. The size of the bang at this origin is bangWeights(tau). The size of the sound at (t) which is coming from this origin is originBangSound(t- tau), since we care about the position of (t) relative to the current origin (tau). Adding them up leads to an integral in the continuous case.

allBangSounds(t) = \integral bangWeights(tau)*originBangSound(t-tau) d(tau)

The point is this. Don't think of it as a flip. Think of (tau) as defining the origin point for a particular "bang".

Here's a nice sanity check: if (tau) is larger than (t), (or equivalently, (t-tau)<0) then do you expect to hear its bang? Ofcourse not. The bang hasn't happened yet. So unless its bang travels backward in time (which definitely does happen in spatial convolutions!) you ain't hearing it.

_____________________________

*Come to think of it, this is a very useful pun. When you think to yourself "what's the origin of the reversal again?", just remember, the moving the origin is the origin of the reversal.
Wow, amazing how varied people's responses to these things are! If I wait too long to take a triptan, its effectiveness reduces quite a bit. I generally try to arrest the migraine with ibuprofen but then take the triptan if it progresses.
I’m surprised as I read when the Prius was introduced that they’d done an educational campaign specifically about this (both battery fires and how to cut the car open without electrocuting yourself). I’d assumed this was a regulatory requirement.

Another hidden issue is that as a container gets close to running out of memory, it furiously drops read only pages from memory, only to need to read some of them back into memory moments later.

This pathological swapping behavior can impact other workloads on the system.

cgroups2 has better protections against this behavior.

I've looked at setting that up for my home lab a few times and when reading the docs I always get hung up on one thing. How do I retrieve certificates on my servers? Do I have to use the Certera API for that?

What I'd like to have is an ACME compatible endpoint so I can change the ACME endpoint in my Traefik config to `https://acme.certera.example.com` and not have to make any other significant changes.

Basically I'd like to have an ACME proxy with a dashboard like Certera.

The problem with nix is that it defeats the purpose of shared libraries. Normally, when you upgrade a shared library, all consumers of it get fixed for free.

With nix every package is siloed into its own separate dependency graph and so you can have many versions of a shared library coexisting on the system but each version may be used only by one consumer. That means upgrading one will not affect all the others.

So then the only way to get consumers of a shared library to upgrade is to upgrade the consumers as well. Well then why not switch to static linking and be done with it? It would be much simpler that way.
Quote: "Something I worry about a lot is that I don’t understand how the internet works. And by that, I mean the entire web, the whole shebang, from when I press “Send Newsletter”, to how Normcore makes it way up and through WiFi and then thick cables somewhere in the darkness of the Atlantic, through seas of malware, bypassing the dark web, and finally finds its way to your inbox, all of it. "

Well, this implies that dark web and the sea of malware are some dragon land in the middle that needs to be quietly trespassed to reach the other safety. But the better analogy is more like current pandemic where people navigate elbow to elbow and some of them have COVID-19, regardless of the physical location. Trust me, your packets can be next to some malware/dark web packets right after they left your router and are still traveling inside your building, even before reaching your ISP gateway.

re: The Economist. "Mask wearing" attitudes in general don't mean much in the context of people who are looking for 100% wearing once you step out of your own door. There are a lot of places that are very compliant indoors, and relatively so outdoors in crowded areas, but not where they're mostly distanced outdoors. To many people, that looks fine. To others, it's horrible.
This requires padding out an O(n)-digit number to memory size O(n log n), with addition operations of numbers with log(n) bits deemed to take O(1) time.

If this is allowed by your model of computation, then you could use this magical O(1) addition to to implement multiplication in O(n).

I'm talking about lower courts such as county/city courts that deal with all local level proceedings. They function just as English magistrates/county courts. I'm not sure how the separation of power has anything to do with these local judiciary. If you talk about corruption that's a different issue.

For me if these courts are exercising their judicial power legally and properly then we at least have a working civil legal system (not 'none'). There are unfair cases with international concerns but it's not unique to China. I don't think a majority of the local courts in China are malfunctioning or abusing power. If you have evidence to back your claim up I'm happy to read that.

I first experienced this as a kid, after playing Guitar Hero for a while with some friends on a gigantic TV.

It took us a minute to realize what was happening. It was a wild minute.

Some of the old Unix GUI interfaces had a literal pin image on the corner of the top bar of each window.

(they could "underlap" though).

While the advertising / data sharing revenue is valuable to them, the vast majority of those are going into homes where they're going to be internet connected already. The cost of a modem + service fees for it wouldn't be worth it for most of them.

Amazon is starting to ship their Sidewalk protocol[1] which will be embedded into a bunch of their devices - but that seems to be mainly for low-power/remote devices to connect back to a Sidewalk access point, rather than to provide an alternative data-path for (say) customer metrics.

I think the modern world is also considered the electrified world. On demand power is what drives the modern world. It enables such luxuries and tools like computers, phones, power tools, the internet, etc. The grid responding no sounds like something that would be out of a 1980's anti-USSR propaganda, and I can't help but feel like such a world would be considered dystopian by most. And we currently don't have the capacity or technology to store electricity for long periods (i.e. by renewables) without another support structure like nuclear or biomass.

Additionally, we don't have electric vehicles/machinery that can adequately replace many of the essential tools that we have today. Try mining on a fully electric system. I don't think you're going to get very far right now. Maybe some of these processing systems could be electrified but not the whole thing (hey, maybe we'd go small modular reactors and that'd power these machines? But I doubt it).

The reason I bring up such things like concrete and steel, besides the logistics of constructing them (again, getting heat is a problem), is because when we talk about fossil fuels it is really a proxy conversation for climate and emissions. It is a danger that we are only focusing on this and not other things.

>> One of the biggest challenges in climate is that the population has been so hyper focused with energy and transportation

I do think Gates[0] wrote a decent article on the subject matter and how we need to start widening our net if we're really going to solve the problem.

Depending on what you want to do you can get good results using tmpfs ram disk in combination with a non volatile USB plugged storage.

Eg: I convert some RTSP stream from a pi zero to HLS on a pi4 by ffmpegging the RTSP stream to HLS files in the RAM disk. I use bindfs to make this mountpoint available as a www-data folder in /home/pi/ssd/web/hls (which is actually on an USB plugged SSD) for HTML viewing in the browser. Motion triggers events, those events can be recorded from the RTSP stream or the ramdisk (holding HLS files) to the attached SSD. The HLS conversion adds a 30 second buffer so any triggers on the RTSP stream has an hls capture starting 30 seconds before the event and the SD card is never touched and I could use a spinning disk, it wouldn't be a bottleneck (but I am somehow more confident the SSD will be more stable power wise).
You can always boot any Linux rescue system (Knoppix) and use gparted to figure out the partitioning, then continue their cli install. I do agree that partitioning by commandline is scary biz. A good TUI (think weechat, htop, tmux quality) would do great for this purpose.

The thing I hate about recommendations on the homepage is clicking one 30 second funny video from a friend results in clicking "not interested" in 30 videos on the homepage to stop them from being recommended. Similarly, even if you use a different account, if you watch something you like and the algorithm decides it's more related to some other topic you don't like or thing you have no interest in it also floods the recommendations with this "fresh" topic you're "interested" in simply because you liked a video it misclassified.

Much like the author I have no problems finding "decent" content from traditional wide audience channels like Tom Scott, Veritasium, Numberphile, Siggraph, etc it's trying to find that 1 video out of the full homepage of recommendations that's not mainstream but actually "very good" and in depth that ends up eating more time than watching the videos - followed by a refresh to apply all of the "not interested"s I added to try to steer away from certain content. Definitely going to try this repo when I get home.

Artificial Intelligence and Intellectual Property
Should AIs own 'their' intellectual property?

The UK government are currently having a Call For Views (CFV) [1] on the relationship between AI and IP (Intellectual Property) -- should AIs be allowed to own IP? A couple of UKIPO's senior staff spoke about the background to the CFV recently on a podcast channel that previously interviewed [3] the creator of DABUS, an AI that applied for a patent.

Should DABUS hold a patent, can a monkey own a selfie, should #aisongcontest [5] songs be protected by copyright, how about DreamWrite's AI written articles [6]?

There is a summary of the CFV questions [4], some people here will be creators of systems to which these issues directly relate.

Also presently the World Intellectual Property Office (WIPO) currently have an online exhibition on the subject of AI & IP [6].

Most of the big webpages are about hosting and sharing content, if we can shift the hosting costs onto the consumer somehow then those applications have no real reason to be a business.

Of course some content on e.g. Youtube is now partially funded by ad-revenue but that seems like something that happened more or less accidentally, and it has some undesirable consequences (hence why people are increasingly trying out other revenue streams).
You bet, that was just one of the many things my grandparents did that made childhood fun for my brother and I. Depending on how young your kids are they may also like the hidden treasure routine.

My brother and I went on a streak of trying to find hidden treasure. One weekend we convinced my grandfather to drive us around to scope out spots to look. My grandpa told us to give him directions where to go. Eventually we found a spot and started digging. After digging a few shallow holes my grandpa pointed to another spot and to our surprise there was something solid about a foot down. It was an old Neiman Marcus tin full of loose change and candy. We were thrilled and for years we would tell anyone who would listen that we had found buried treasure.

When I was an adult if finally occurred to me that my grandpa had set the entire thing up. There is just no way my grandparents would have let us eat candy we found buried in the ground. But he had set it up well enough that my brother and I didn't notice. We believed we had given him directions to the place it was buried and we believed we found it after searching the area thoroughly. Really, he had buried it earlier before we came over and gave us subtle hints until we found it. We were four and six at the time.

When I realized it had been set up I called my grandpa and we had a good laugh. He told me not to tell my brother before he hung up. Keeping the secret is key.

Show HN: Sortado – Organize your Google docs, from within a doc
Try mechanical/civil engineering in Canada.

Most projects are metric, or at least, I prefer working in metric when I can. However, things like raw materials (ie sheet steel and similar) are only sold in us customary units, or worse, gauge measurements. Cutting tools for machine tools (drills, mills, lathe inserts, etc) are also much more common in US units than metric

I'vr pretty memorized the millimeter equivalent of most fractional inches, up to sixteenths, by now. I've also worn the silkscreen off the 2, 5 and 4 buttons and finally broken the 5 switch on my previous calculator, bfrom the sheer number of multiplications and divisions by 25.4 I've done.
anyone care to help me understand why the posting is flagged?
I’ve been frustrated time and time again with Google Drive’s clunky UI and search ability to find relevant docs and files, especially when projects have taken on different names.

Sortado is a chrome extension that adds a sidebar to your Google doc to make it faster to organize and find files. We’ve been using it at our company, and I wanted to take the product and make it available to others. I took notes from Notion’s sidebar, but I honestly just prefer the UI and accessibility of Google Docs, so wanted to customize it to make a better experience :)

Taking my first GKE project (done essentially as two man team in the side, and then maintained at quite low level of work most the time)...

The vendor whom we replaced = somewhere above $5000/mo (just infra)

Our final, most costly, GCP spend, including support contract = about $2000/mo (this involves a bunch of inefficiencies caused by developers unable to live with container - or dynos)

Expected Heroku cost, based on their online calculator= starts at $3000/mo, probably more

Expected lower time needed developing on Heroku = negligible

Fortunately it was a transition we'd already talked about making; we were approaching that threshold where the agility/reliability tradeoff was about to flip. But still, it sucked having a few hours of unexpected downtime while we scrambled to make the change.
I've had a similar experience. Anything I don't want to litter my recommendations I view from a private window. If I accidentally click on something I don't particularly want to watch, I remove it from my history.

It's not perfect, because as you go down the YT rabbit hole, you'll invariably get fed "top ten X" type clickbait videos if there's anything that's remotely related to what you're watching, but it does reduce the noise level.

Help me understand how this bribery works. If someone "donates" iPads to "the Sheriff's Office", does this mean that they can be taken by people who work there (for example, Sung could sell them on and pocket the cash)? What is the mechanism here? The cut-and-dry case would be asking for a cash bribe and pocketing it, so is this a way of making the bribe look like something else?
