> If the quality of the measurements are high enough, and the sampling frequency is high enough. Then the Kalman filter should be able to converge to a very good estimate of state, even with no motion model right?

No. Consider this discrete-time linear system with 2-dimensional state [x1, x2] and one output y:

x1' = 2 * x1
x2' = x2
y = x1 + x2

Suppose we see the output sequence 1, 2, 4, 8, ... If we know the motion model, then we know that the initial state must have been [1, 0]. (In technical terms, the pair (A, C) is observable.) But if we don't have the motion model -- all we know is that y = x1 + x2 -- there's no hope of ever getting a state estimate, even if our y measurement has zero noise.
You got me thinking...I still run my MSI Wind netbook (RIP Zareason!), and it's worked great with both Haiku and Q4OS recently.

The keyboard is a near-disaster in some ways but after configuring a bunch of workarounds it's reasonably comfortable.

I took it on a trip to Sicily soon after purchasing and have fond memories of using it and my n810 "media center" for that trip. I didn't have WiFi at the guest house where I stayed so I ended up getting my work done from the front of a tiny cafe in Noto, stooped over the tiny screen, but very much geeking out.

The form factor is still really kind of cool when I'm in the mood to play with it, but once anything with cords needs to attach to it, it starts to look kind of overwhelmed IMO.

Still, to this day I'd rather build stuff on it than on my phone. But that probably has a lot to do with things like muscle memory, maybe in addition to the fact that a properly-configured desktop OS (esp. with keyboard workarounds) is just something else when you're ready to work.
How else do you think the sausage gets made?
Would you call "booting" what Windows does with Fast Startup enabled, then? It is half resume from a hibernation image (kernel and system services), half going through the regular booting process (rest of userland).
Yeah, apparently the marketing material is big on everything, except updates.
I remember that I was tuning a 1TB sql server database on a 10" eeepc/USB disk to prove a client they badly misconfigured their server, I was getting 10times higher txn performance

Started with 701 with a 3g key, continued with 10" one and then in 2011, the MacBook air 11",these years were peak IT, dev and fun for me.

Light, powerful enough, connected and the pricing wasn't too bad (hi2u Sony books at 2k+)
Media prior to social media MASSIVELY shaped our culture.
TikTok has its share of enraging material if you go looking for it. The genius of their presentation is it effectively doesn't exist unless the algorithm decides to show you that content. When presented with that content, if you scroll away fast enough, it won't be presented again.
Because python is #2 on the most used languages list, has great tooling, IDE support, has been around for 30+ years.

It's been used to build serious large scale projects.

The idea is that you can get great runtime performance by transpiling. This is how Facebook worked till 2013-2014 (php -> C++ transpiler).

It's unfortunate that google abandoned the grumpy project. But many good alternatives around.
Is there any reference for this? Haven't heard this before
That has worked flawlessly since day 1 in Jun 2020 for me.
Got source? The social media market in China is fiercely competitive and TikTok (Douyin) got to be king of the hill by delivering exactly what its users want, not what the CCP wishes they wanted.
Get alerted by Telmai, instead of being alarmed by the Business team!

We are re-launching our complete data observability product.

We are excited to re-launch Telmai as full data observability product to this incredible community!

What is Telmai?
A data observability product that helps data teams proactively detect and investigate data issues closest to their source before having a downstream impact.

How does Telmai work ?
Watch this short 3 minutes video.

What needs do we serve?
Data teams are struggling today to detect data issues as soon as they occur — these issues are often first experienced by data consumers and cause long and tedious investigation cycles.

With today's fragmented pipelines, every step in the pipeline can become a point of failure with myriad issues such as incomplete data, data type changed by the source system, a mapping error, regex and pattern changes, microservice failure, etc.

Telmai can proactively detect and alert on such issues at its source, and once alerted, finding the root cause is quick using the interactive investigator UI.

What are some core features of Telmai?
Automatic monitoring on 40+ predefined data metrics like schema change, row count, completeness, uniqueness, patterns, distribution change, accuracy, etc
Simple UI for expectations/rules - no more hand coded rules using Great Expectation or DBT expectations.
Monitoring for streaming and batch data sources: AzureBlob, GCS, S3, Snowflake, BigQuery, Firebolt, Redshift, Pubsub, Kafta & kinesis.
Support for semi-structured data i.e., nested and multi-valued attributes.
Support multiple formats like JSON, Parquet, CSV, and Avro
Intuitive human-in-loop model for fine-tuning thresholds, policies, or writing expectations
Spark processing to enable infinite scale without performance impact
Private cloud and SaaS offering
What are the benefits of using Telmai?
Simple, no-code on-boarding
Reduce escalation on data issues
Faster detection and resolution of issues
High-security design

How to get stated ?

You are all-set, if these steps more than 1 hours take extra 10% off ;-)
You Don’t Lack Motivation to Get Started, You Lack Clarity
I actually worked briefly with an engineer who claimed to have seen the inner workings of the TikTok algorithm when she was consulting for them (she was a software engineer and mathematician), and I was very surprised to hear her say that there was no ML involved in the algorithm! Of course, I'm not sure I believe her, but it definitely raises the question of whether an algorithm of TikTok's caliber is even possible without ML.
Was there ever a time in recorded history where this was not claimed?
Yeah, in this case, from memory, the spec author had a list of class names from a scraped HTML data set. He looked at the most common classes — nav, header, footer, and so on — and declared they should be made native elements.

Which would have been fine, except even the most obvious ones (header, footer) were given very idiosyncratic definitions, and others (article, section, aside) were seemingly thrown in at random.

This led to absurd examples where, as is still in the spec, a blog comment is an <article> and the comment's header is a <footer>. This of course undermined the original premise -- that these elements were just 'paving the cowpaths' of how people were authoring HTML, but the spec author would have none of it and shipped them all the same. And here we are. :)
Took a few minutes but I realized that white downgrade was clickable. The color and text difference threw me off.

I do have a question about plans if you happen to know the answer. I see there's an option to share an app publicly (I'm assuming this wouldn't require people to log in to view?), but when I select it I'm shown and error that my current plan doesn't support this. But when I go to view the plans none of them mention a public view feature so I have no idea which one I would actually need for that.

Also do you guys have any programs to sponsor small open source projects with free or discounted higher tier plans? I'd love to migrate my open source project over (a dashboard that tracks various metrics), but I would need the publicly viewable options and I'm not sure I can cover the cost since I'm doing this pro-bono.
Well yes, wages have gone up for low paid industries in the UK after COVID and Brexit due to shortages of workers (my local McDonalds is advertising at £12 an hour now), and fuel and gas is largely being driven up by cutting off Russia. It’s going to get worse before it gets better.

> But put yourself in their shoes: if you wanted to learn how to make a Botan shrimp nigiri (perhaps that's new to you), how would you learn about sushi rice, how to buy live shrimp, how to fillet the shrimp, preparing wasabi, etc? We hope this model can apply

I typed "botan shrimp nigiri" into Google and got detailed videos showing me how to prepare, fillet, cook the shrimp. Most full recipe videos explain side bits about what to buy and things like that.

> The dirty secret is that by the time you get to the end of the quizzes, you'll already know how to cook the hamburger. The recipe is ridiculously elementary.

Here's where I think there's a disconnect.

Why would someone not start with a recipe which shows most of this and then look up the bits they are missing?

You seem to be then targeting someone who wants a broader base understanding of cooking at home, so why would a basic cooking course not be the structure?
If you're using a dedicated server the IPv6-only option is like 2-5€ depending on server (and auction), so definitely worth in all cases.
Same here, on an Eee PC 901. It was a bit slow compared to a real Mac, but ran surprisingly well, resulting in quite a fun little machine with OS X.
My S10 still gets updates.

I've never actually noticed any difference after almost all of the updates since I purchased it. I'm assuming they either have all been security, "stability" or features that Samsung already had provided in their fork.

Nothing. People do that all the time - there is a huge community for aftermarket custom ROMs at places like xda-developers. However, I would guess that is like less than 1% of users since custom ROMs a) are not popular b) require some courage and technical knowledge c) often void the official warranty.
Everyone's TikTok experience is different. Although sometimes you do need to long-press on a video and say you're not interested, the experience as a whole tends to be relatively finely tailored per person.

For example, many of my videos for a long time were basically short essays about current events, relationship advice, (edit: BIPOC) creators, interesting skits or stories about Marvel or DC characters and so on.

Silly dance junk and pranks are certainly not what I see. There is _some_ dance stuff, but it's in subgenres I'm interested in and so I've given those the watch time.

You can curate yourself to things you're interested in. It's not that hard and it's strongly recommended.
People have been saying that for centuries or longer. Kids these days have shorter attention spans. People said it about millennials, about gen-x, about baby boomers.

There’s a record of people complaining that kids are ruined by their reliance on writing things on paper, rather than slate.

There’s a record of Socrates complaining that the written word is ruining people’s memory. The record exists because Plato wrote it down.
As databases were evolving and migrating to the cloud, the data models were changing too. Most modern cloud data warehouses or data lakes now support semi-structured schemas. Today pretty much any big data platform supports working with NDJSON, i.e., New Line Delimited File, where each row is a proper JSON representing a record. And even native support of JSON schema type: [https://cloud.google.com/bigquery/docs/reference/standard-sq...]

This brought a great opportunity for data architects to design the most efficient data model for storage and querying. However, at the same time, it created a challenge for Data Observability. And the reason is multi-value fields, aka arrays. Such data requires special logic to properly calculate basic data quality KPIs like completeness, uniqueness etc. as there can be some records with no values vs multiple values per record.
This blog highlights how we address monitoring for semi-structured data
TikTok itself will have faded. Massive propaganda machines with builtin surveillance hidden behind quick dopamine fixes will only have improved. Do you think the media world will abandon such a massively popular concept?

I mean, TikTok is just the evolution of Reddit or Facebook.
You can also long-press on a video and say "not interested" if you never want that stuff again.
> Facebook, it seems, is moving away from its traditional focus on text and images, spread among people who know one another, to instead adopt TikTok’s emphasis on pure distraction. This shift is not surprising given TikTok’s phenomenal popularity, but it’s also shortsighted: platforms like Facebook could be doomed if they fail to maintain the social graphs upon which they built their kingdoms.

This. I on occasion visit Facebook to keep up with what friends are doing. If they turn it into TikTok, I will have zero reason to go there any more.
EveryCircuit is also an alternative that focuses on circuits in general, not only digital ones
The quote you pull says that, in order for a mask to work, it must be well-fitted and of a high quality. And then it defines high quality as being N95 or KN95.

Cloth masks don't meet any standard of quality or well-fittedness, so I'm having difficulty seeing what problem you think exists in the restatement by Reason.

I also can't tell what you mean by "no mention of the surgical masks". What surgical masks? Surgical masks aren't mentioned in the quote from Fauci or the quote from Reason.
Many, many people in UK use GOOG pay (wallet now) to pay for goods and services. A few contort their wrists to show off their Apple watch, but phones are more than commonplace.
It behaves differently of course, and the pictures would be massively distorted. But with some image processing it should be possible to do some analysis. One of the recent JWST images shows an example where a massive galaxy cluster makes redshifted galaxies behind visible.
I love working with notebooks but hate the .ipynb file format with the burning passion of a thousand suns.

For those of you who are similarly affected, you may want to try jupytext. It is a tiny package that converts threeway between ipynb, plain python files (whose comment blocks are interpreted as markdown cells) and plain markdown files (whose code blocks are interpreted as code cells). Moreover, if you have jupytext installed, then jupyter will read and write python and markdown files transparently as notebooks so that you don't need to deal with the stupid ipynb files anymore. This is nice because then you can track the evolution of notebooks easily in git, and your local graybeards can edit notebooks with a plain text editor, with no need of a web browser at all.

Of course, the output cells are not saved, but this was always in bad taste anyway. If you want a nice html with the cell outputs you can run "jupyter nbconvert --execute --to html" from the command line (and yes, it will work with plain python or markdown files if you have jupytext installed).

Why this is not part of jupyter proper is beyond me.

EDIT: regarding nbdev, I would like to learn what are the advantages with respect to the minuscule jupytext thing. I'm particularly concerned by the soundness of the quarto dependency, which is a scary behemoth made by accretion of haskell and javascript.
The economic term for this is industrial policy. The wikipedia writeup is thin and US-centric but has some valuable historical context.

Well… I do hold my phone in my left hand, but I’m also left handed. The one handed feature would be useless.

The issue is that when companies produce product like this, which ignore left haneded users, I get suspicious: What other details did they overlook?

It’s most certainly just a cost issue, ignoring 10-15% of potential users is cheaper than building two versions.

Like the other comments mentioned your post misses of how transparent AWS has been in price reductions in the past.

More importantly, S3 now has several tiers of pricing depending on how frequently you access the data. So maybe lately they haven’t reduced the pricing of the top tier of S3 but they’ve made it significantly cheaper for other use cases of data. That is very contrary to the comments being made of innovators dilemma.

(I used to work at AWS but have no knowledge about pricing decisions)
Why default to blaming the students/employees?

The educational system and employers have a responsibility to be engaging and enriching if they want interest and passion back from their students/employees.

I'm not saying there's no problem with overconsumption of cheap media. But I think we're too quick to jump to blaming individuals. We can just as much flip the question around and ask what educators and employers are doing to keep students engaged and feeling motivated by what they do.
To me, SE stands for "Steve's Edition".
I was actually thinking of places like India in my original comment. Dairy is how those billion nourish themselves. Not just amino acids but important vitamins and minerals as well.

A world where "we have plenty for what we need with just plants" may be a possible world, but it's not the one we live in now. It seems like it would require immense effort to get there.
This is a great point regarding walled garden vs repositories with respect to choice.

The original point though was implying repositories were better because they are trusted.

However if choice allows trusting a new repository you just came across, choice similarly is fine to trust an .exe from the internet too.

Not advocating for random .exe installing BTW. But honestly, for 99% of what we do we make trust choices based off Reputation and Probability guesses for outcome. We mostly don't have a clue what the executable code will do exactly.

In this case, I have a hunch that a well known repository is likely not to feed me malware. But I also figure that VLC/7-zip/notepad++ probably won't either. So will happily download their .exe. And I don't want anyone removing that option.
Hopefully I’ll be able to write up a similar article. Going to bodge an Aliexpress repeater together with a directional yagi and an omni indoors so that it’ll work with anyone’s own device for that provider.

Signal on 3G is okay but wanting to see if I can shoot for stable lte.

Won’t be bothering with MIMO for now just for simplicity. Canadian monthly limits are too low to be concerned with maxing out bandwidth.
Have you considered large successful software projects have been done without any of these modern tools or languages? Or are your projects more complicated than the moon landing?
Same goes for cups.
typically LineageOS uses the stock binary blobs for cameras, too many trade secrets for Qualcomm, Sony, Samsung etc. to release them as open source.

you can bootloader/oem unlock zenphones, though that might wipe DRM keys.
Not sure about you but my TikTok algorithm just shows anime hot takes, quick facts about world events, and a goat named Billy Earl who can't stay off of the neighbor's damn house.

If all you see are pranks and dances it's probably what you went on there looking for.
I have been using band pass filters and didn't know about Kaiman filters!
I feel like the knowledge graph idea only works at a higher level. Rather than "how to buy an egg" unlocking "how to store an egg" and then "how to boil an egg" I want "hey there's a thing called mirepoix that's pretty fundamental, learn how to do it properly".

I learned about lactofermentation, it's really easy and opens a huge range of things.
I'll check it out again myself if there is a useable free plan! We are paying 20k per year for some apps we got hooked on for free - nothing beats actully trying product and I'm often so busy it takes 45 days to get back to something

I guess div/span don't offer much but I assume the screen readers etc. at least have experience dealing with that vs. randomness.
> Why do you think it's satirical?

I'm not the person you were replying to, but I think it's satirical because it's kind of funny, it's written in a style of exaggerated confidence, it's worded in an unnecessarily inflammatory way, and it has amusing diagrams. That doesn't mean I think it's just meaningless nonsense; a lot of satire does have something interesting to say about people or society. But I also don't think it was meant to be taken 100% seriously either. And maybe satire isn't quite the right word, because it's not really satirizing or parodying anything in particular other than overly pretentious essays.

> Check out the screed on gay marriage.

That wasn't written by Cipolla, they just happen to be hosted on the same site. The argument seems to be that government shouldn't be involved in defining marriage in the first place, for anyone. I agree with that. But since there are practical reasons why a society should want something like a legal notion of marriage recognized by the government, the part I would add back in (which wasn't part of the "screed") is that consenting adults should be able to mutually agree to formally recognize each other as belonging to the same family, and that should be recognized by the state. We can get rid of the unnecessary notion of applying a special legal status to the person you're sleeping with and allow people to form families for any reason, without necessarily any implication that they're sleeping together, and we can apply certain legal rights to members of the same family, like the right to jointly file taxes or to be on each other's health insurance plans.

Obviously there would be a lot of weird side-effects, corner cases, and implementation details you'd have to work out for that to be a workable thing.

Nowadays when researching a new phone I just immediately go to see if it's got a 3.5mm jack and to my surprise it does! That automatically makes it a step up from all the competition that refuse to let the trend of not including a 3.5mm jack die.
I agree with you wholeheartedly on the app.

There is so much wealth and context when it comes to food. Every region, culture etc has their own ways.

Like a sibling says to store pieces of cheese that you won’t use in a freezer.

I can imagine that framing all of the questions in the right context all the time is hard. But now it seems to be a bit too simple “know-it-all”.
I had a couple of LG phones, both of them ended up getting a hardware fault. Both times I sent them in for service and the only response I got from LG was that somehow I made it damage itself. There was no replace, repair or purchase a replacement option. Just an email saying I was SOL, k, tnx, bye.

I found the phone quality to be bad and customer service to be bad and avoided them. I was not surprised that they didn't survive.
For reference, my server CPU is an AMD Ryzen 7 PRO 5750G (65W TDP, 3.8-4.6GHz, 8-core, 16-threads) and CPU usage is around 8% when writing at 700 MB/s on my raidz2. In other words, only a little more than 1 of the 16 hardware threads is utilized to handle this workload. Your older Xeon D-1521 should be able to handle that, but it's true that being an older processor, it is pushing it closer to its limits. Handling concurrently 10 Gb/s of network traffic would likely push it to more than 50% utilization. That's one reason I like to not cheap out too much on the CPU, especially for a 10GbE ZFS NAS.
