Show HN: 4d-Modeller – R library to make Bayesian spatiotemporal modeling easy
Hi, I've been working with other colleagues at University of Bristol for the last year to build an R-package that makes bayesian spatio-temporal modeling easy. That is, if you have some problem like predicting sea level rise over time, disease transmissions, etc., this package may be useful for you. It centers on a collection of Shiny apps that guide you through using the various pieces of spatio-temporal modeling packages like R-INLA or inlabru. Hopefully people find this useful. I think the nice part is that we really tried to design the package so you can add it to your modeling tool kit without having to learn a lot about R to be useful with the tool. Hopefully we succeeded.

We will have a hackathon for this model in March 25-27:

https://4dmodeller.github.io/4DM_Hackathon/

At the hackathon we will implement new features or apply the model to new applications.

There's no realtime tracking, the activities are uploaded to Strava after finishing them. It can become a potential security issue if you upload activities from far away from home.
Back in the day terminals under Linux did that to fake transparency: they just copied a chunk of the
root window (where you put some wallpaper) as the terminal background and applied an alpha layer if the user wanted a translucid color.
Not exactly. You can see all public dáta and the data your "friends" (person you follow) share to followers. There exists really private data too.

Btw. Strava did add a "don't show GPS 200m near my home (or any other location)" feature some time ago. But I guess that still isn't the default.

So is it really the 'risk' or simply the number of reported occurrences? The periods above seems to be those when people are more likely to have sex.

Two things prevent this tech from being deployed by more stores.

1. Cost of RFID tags, they’re very cheap, but still an order of magnitude more expensive than barcodes and have a meaningful impact on item costs in some markets (notably groceries).

2. Supply chain problems. This is actually a much bigger issue than the cost. RFID based checkouts require a store of have every single one of their suppliers integrated the tags into their products. Most shops simply don’t have enough control of their supply chains to make that happen in a reasonable timeframe. Until every product on the shelves has tags, you can’t deploy new checkouts, but you still need to pay for RFID tags you can’t use during the migration.

Decathlon have RFID based checkouts because they mostly sell their own products they’ve designed and had manufactured. For the vast majority of their products the RFID tag is stitched directly into the product, so it’s not a label that can be easily peeled off, or fall off. For the small number of 3rd party products they sell, they’ve got enough volume to get other suppliers to integrate RFID tags, or they can use removable labels because the risk of lost labels is acceptable if it only applies to 1% of your stock.

So don’t expect to see this type of tech deployed elsewhere anytime soon. Decathlon’s extremely strong vertical integration makes it substantially cheaper and easier for them to deploy RFID, compared to most other ships.

Probably what "reduced you to tears" was not the Beatles itself but the personal experiences that you had with this music. It is an emotional anchor that companies are eager to exploit.

For me it is a way of extracting more money out of nostalgia from subpar works. I personally believe The Beatles disappeared when Brian Epstein died and the group(as bigger than the sum of its parts) could not remain united.

I see that all the time with people with things like their first motorbikes in exhibitions. For me, they are noisy outdated machines. For them it was freedom, it was how they impressed their first girlfriend or their first travel with friends and all the experiences that came from it.

Their first cars, pinball machines or more recently a commodore or a sega genesis, NES, play Station... as people that are getting older and making money can remember younger times.
Would love to see that implemented here in USA. People in places like NYC love to catch and spay every cat they see, then go on to complain about too many rodents around.
Omni Commons in Oakland is at a critical juncture in its history and we may lose the building in 2024. I was just at a rather passionate three hour meeting about it yesterday.

You’re not imagining things. It’s hard to sustain places like this when private equity firms are buying up all the land to build high end apartments.
As a kid I acquired my parent’s login to the school platform meaning I could call in sick myself. However one day I actually got sick so they had to call it in which means they would’ve seen all previous calls.

So I downloaded the HTML for all pages required for this exact flow and removed the previous sick days. I then changed my etc/hosts file, gave them my computer and prayed that they wouldn’t try to visit any other page than the ones I downloaded.

Worked like a charm. Later I called in sick myself.

> my point was that to the human mind (we all learn to count as toddlers), 2 emerges from 1+1 more than 1+1 emerges from 2. I feel like I'm reading the paper that says the latter.

When you crack an egg you say the egg yolk emerges. Similarly you can say that when you crack the classical mechanics shell you get parts of quantum mechanics. We didn't start from quantum mechanics and built up to classical, we started from classical and picked it apart until quantum emerged.
It is not local. That’s what’s wild about it. It’s a minimum over all paths. Re-read that section you posted.

Indeed, Andersen-Lake method is much faster, but is limited to vanilla problems.

I was confused what kind of "slides" this post was about when reading the title/intro, so in the interest of fighting clickbait: It's about designing PowerPoint slides, not playground slides and not UI sliders either.

Though I'm slightly disappointed there isn't a 10 part series about the principles of playground slide design.
The tags are usually stitched directly into the clothes. Realistically they’re never going to be recaptured and returned. They’ll be recycled/disposed of, when the garment itself reaches EOL.
Any ideas on what the "right way" would be in this case?
To me the solution seems the most straightforward.
I use GPT-4 to generate a poem as a reward for solving the daily puzzle at https://squareword.org The poem is based on words from the puzzle.

It usually manages to create a reasonably coherent and amusing poem from up to 10 completely random words, something would struggle to do myself. People tell me they enjoy them, although some of the poems turn out a bit odd haha.

We don’t. It’s usually not hard to source actual statistics (and when it is, that’s usually an indicator that ChatGPT is completely wrong).
I suppose that heat exchanger ventilation makes most sense at winter time. Not everybody lives in San Diego, a lot of people live in New York, Boston, Chicago, Seattle, etc, where a winter is a thing.
This reminds me of something I encountered when working on surgical training simulators about ten years ago.

There was a function which needed to traverse a large (a few million vertices) mesh and, for each vertex, adjust its position to minimise some measurement.

The original code, written by a colleague, just calculated in which direction to move it and then, in a loop, made changes of decreasing magnitude until it got close enough.

This function was part of a performance bottleneck we had to solve, so I asked my colleague why he hadn't solved it analytically. He shrugged and said he hadn't bothered because this worked.

So, I rewrote it, calculating the exact change needed and removing the loop. My code took twice as long. After analysing why, I realised with his heuristic most triangles required only 1 iteration and only a handful required at most 3. This was less work than the analytical solution which required a bunch of math including a square root.

The new construction doesn’t have to be targeted at low-priced rentals. If higher-income renters move to the new construction this frees up the older apartments for lower-priced rentals. What matters is the increase in supply.

I think 11m monthly users is a lot. Sure, compared to Facebook 2023 it's minuscule. But assuming those 11m monthly users log in 2 times a week (~8 per month) and check out 15 pages each time that comes out to 1.3bn pageviews a month. Divided by (60s/m * 60m/h * 24h/d * 30d/m) comes out to about sustained 500 pageviews per second.

I assume since they're a viral / addictive platform the numbers will be higher. Plus they're not a blog or so, but rather a personalized social media platform, which makes stuff more complicated (you can't just cache their news feeds, they're all personalized).

It's easy to say meh, 11m is nothing, there are other platforms with more users (esp. since you don't bring up examples how you managed otherwise). But I think it's a big technical feat to do this with 6 people.
When I was a teenager my GPU fan broke, but i happened to have a spare CPU fan. I modified the connector so it would fit and just tied the fan upside down under the GPU with a string. It made an incredible amount of noise but worked very well.

Fixing a CD drive with Polish Kielbasa:

The CD drive in my first computer broke. We couldn't afford to get a new one, and after almost a year of using floppies I got a bit tired of having to carry them across the mountains every time I wanted play a new game. (context: I lived in a small village in southern Poland at the time -- imagine Twin Peaks, but with fewer people and bigger hills). Sometimes getting a copy of quake or Win 95 took several trips back and forth as I didn't have enough floppies and the ones I had would get corrupted.

I turned 10 and finally decided to disassemble the drive and try to fix it. I found the culprit, but I realised that I needed a lubricant for one of the gears. In that exact moment my little brother was just passing by our "computer room", eating a bun with kielbasa (the smoky, greasy kind which is hard to find outside of PL). I put some of that stuff on a cotton swab, lubricated the gears in the drive, and magically fixed it. The drive outlived my old computer (may it rest in pieces). I miss a good Kielbasa Wiejska.
At university we were tasked with making an Android application for a real client. This was part of our course and was really fun to do. Especially because we did this in two groups competing with each other. The app was some sort of geocaching mixed with a quiz to discover a city in groups. We also built a server side app that accompanied the clients. This app was targeting Android 2.3 and ran on some sort of old Xperia device.

Building the app was a lot of fun and it worked pretty well most of the time. During beta testing however, we were given all the resources that were crreated by a third party. This mostly included UI elements and other images that made up the UI. Testing it out, again, it worked pretty good. Until one time it didn't...

After about an hour or so of playing, the app would consistently crash. After some OS troubleshooting, we came to the conclusion that apparently Android (at the time) had the habit of not putting images in managed memory, but separately. And whenever this space overflowed, an app would simply crash. To resolve this you would need to manage this space yourself and clear out memory.

However we only discovered this a week or so before the deadline. And implementing memory management would be nigh impossible to do. So I came up with the hackiest solution that I ever built. I added a crash handler to the app, which would start another instance. I also added a serializer / deserializer to the app and whenever you reached the main menu all play progress was serialized to storage. Whenever the app crashed and restarted, this was read again and letting the users resume play. The only side effected was some weird app flickering because of the crash and restart.

A week later when we delivered the app to our clients, they wanted to try it out and play test it. So we did, along with the other group. And lo and behold, after an hour or so the app crashed. And restarted. Unlike the other group, were the app crashed and had to be restarted manually.

In the end the client was really happy with the result. Because it just worked. AFAIK the app is still in production the same way it was about 10 years ago.

i think heat exchanger ventilation makes roughly the same amount of sense whenever you're spending costly energy to change the temperature of your space, doesn't it? it works just as well to keep summer heat out as to keep winter heat in, and staying cool in summer can be just as critical as staying warm in winter, depending on where you live

the main difference is that you can heat up a house (inefficiently) with a nichrome wire or a gas burner, while cooling it requires considerably more elaborate equipment

but if electricity costs 2¢ per kilowatt hour and daytime electricity is free, will the savings of a heat exchanger be enough to pay for the device?
People die of hunger and you are seriously upset about a blog post.

No, women might actually be conscripted too, as some presidential office members directly mentioned in interviews, and a couple of TV's had incidentally done impromptu "video polling" in the streets of Kyiv.
Consider reading the article.

"Fast Retailing began testing RFID tags in 2013, introduced the self-checkout machines in 2014 and switched to the current model in 2019. They came to America on a trial basis in 2021, followed by an official rollout in 2022. This was the year they arrived in every Uniqlo store in the U.S."
They can also serve as memory anchors/reminders to people after they saw your presentation.

I also like the way Maciej Ceglowski archives his presentations: Slides, with little to none text in the left, combined with a summary of the actual talk on the right. Makes it extremely easy to retrace the talk from the archives and even get all the jokes and rethorical devices from the original presentation.

Example: https://idlewords.com/talks/haunted_by_data.htm

(Imagine if he was just giving away the slides on the left without any text, it would basically be a random collection of images without any understandable meaning)
I've used several laptops as file servers in hot apartments without AC and haven't had issues. The trick is to make sure you're not running a bunch of bloat you don't need (which is the root cause of 99% of "my old computer became slow") Slap something like debian on the laptop and don't even bother installing a desktop environment. The load of an NFS server sitting there idle most of the time and a few other system services doing basically nothing is negligible, any laptop should be able to handle it in 40 C weather. If not then you probably have some dust issues, so blow it out and see if the issue resolves itself. Keep the screen partially open (you can turn it off though) to help with ventilation.

I've never had any laptop die while operating like this. I only replace them when I replace my primary use laptop with something new, demoting my last primary use laptop to the server role.
I think people commenting how overblown the architecture for Pinterest is haven't seen a true Pinterest Person in the real world.

There are people whose lives rotate around having different boards on Pinterest. They collect ideas for recipes, interior design, clothing, vacations and _everything_ on Pinterest. It's not a site where people click three links and come back in a week for their next three clicks.
What’s the point in seeing this through then — ultimately a lawsuit just delays the inevitable and will be more costly for Twitter considering legal fees.

I think they must be penalized, because I see this a lot less in the results than I used to.

And byw (unless we are talking about different things) it was possible to get to the image on target page, but it was walled off behind a log in.
I know exactly what you're talking about. The product manager on the project described above added little value. Luckily, they were so ineffective that they didn't get in the way often. I've had others who were "excellent" at getting in the way.

That said, three of the most impressive people I've ever known are a former marketing exec and two former product managers, all of whom now work in VC. In their former roles, each helped me be the best engineer I could be. The people in their current VC portfolios are lucky to have them as advisors. What makes them so good is that they bring expertise worth listening to, and they clearly value the technical expertise brought by engineers. The result is fantastic collaboration.

They are far from typical, but there are truly great ones out there. Losing hope of that might make it more difficult to be aware of the good fortune of working with one, and maximizing the experience. My hope is that every engineer gets at least one such experience in their career. I was lucky enough to experience it repeatedly, working with at least one great one for about half of my 30-year career.
When I was a teenager I had a bbs running on my computer. When I wanted to play, I just opened the line with a phone so it would be busy if someone wanted to call. Oh the memories.
I've noticed it too. Lots of anti EV posts and comments on the major forums. It feels like a sustained global PR operation by some people with very deep pockets and an obvious agenda. I wonder who that might be?

Shein is bad for the planet and bad for humanity. They profit through exploitation; mostly of their workers (breaking even Chinese labour law), ripping off designs, dodgy marketing practices, skirting local tax laws and employing dark UI patterns. Their clothes are so low in price and quality that they are often worn once and thrown away. At $40B GMV they are bigger than most of their competitors combined; fast fashion on steroids, flying under the radar. Their mere existence is accelerating the destruction of the planet and feels like a distopian hell hole that won't be stopped.

It works something like this;

1. Somebody uploads a design they found (probably stole) and creates a piece of clothing

2. Somebody else with just a shred of desire clicks on a couple of buttons and pays $3.78

3. A Chinese sweat shop worker immediately picks up the order and creates the piece of clothing and gets paid $0.03 for the trouble (whilst working 18 hour days in leui of any breaks, weekends or holiday)

4. The clothes get air shipped across the world and delivered to the customer, skipping customs and taxes

5. The customer, who basically forgot they bought the clothes (it was after all purchased in a tiktok haze and didn't affect them much financially) trys on the item, takes a photo, and throws it in the closet

6. A year later it gets donated to charity, who assesses the quality and redirects it to landfill
