Data Privacy efforts are heavily slated to impact Analytics quality / volume in the next several years.

On the technical side we have things like Apple's Intelligent Tracking Prevention, App Tracking Transparency, Mail Tracking Transparency and Link Tracking Protection, Chrome is finally about to phase out 3rd party cookies and browsers like Firefox and Edge lock down or block common web tracking technologies. - just to name a few. All of this combines to add noise, or a reduction in volume which impacts analysis efforts.

On the regulation side, we have global laws such as Europe's GDPR, 4 US States with current data privacy laws in effect, and a total of 12 US slated to take effect before 2026 - all of which are slightly different in impact scope. This results in scenarios that even if you technically can collect data, you may not be legally allowed to, or, alternatively prevented from using it in specific ways.

This will force companies to switch back to Media Mix Models for attribution and adopt new privacy focused solutions for existing use cases to some extent.

Data analytics is getting more complex, not less. However that results in a massive amount of needed learning on a continued basis - which may not be for everyone.
Kilogram is a measure of mass. The fact that hydrogen is buoyant in our atmosphere doesn't make 1 kg of hydrogen any less.
GSV also shows user-submitted photos.. e.g. https://maps.app.goo.gl/wHQ3645j3EkaazC8A

Hydrogen is generally stored compressed at 700 bar. At that pressure the density is 42 kg/m3, or one kilogram per 24 liters. Roughly one kilogram per one jerry can.
“Give me a ban interface with unlimited access” is more like it.
Does your mom know what Bluetooth devices are?

Maybe the better icon would be something that just refers to “connected devices” rather than a protocol. And in doing so it even makes a bit more sense for things like AirDrop that may use a modified version of the protocol or a mix of Bluetooth and wifi (I think it negotiates via bt and transfers via wifi?).
That was my question exactly.
The thing is that there are now multiple independent lines of investigation pointing to LK-99 not being a superconductor, and explaining away the original "smoking guns" offered by the authors.

It's like we have a murder suspect, the murder weapon, and fingerprints lifted from the scene. At this point it could still be space aliens, but nobody in their right mind would treat that possibility seriously.
I liked the gumdrop iMac, really liked the G4 towers, but absolutely loved the sunflower iMac. It's still one of my favorite computer designs of all time, followed closely by the original G5
Real-time analytics for human is not that useful. Human can't make decisions and take actions in minutes anyway, let alone seconds. A notable exception can be log analytics for operations, but I'd argue in that case throughput is more more important than a few seconds of latency. Case in point, CloudWatch Insights can consistently drive about 1GB/s of log scan. It's good enough for log search in practice.

On the other hand, real-time analytics for machines can be critical to a business, which is why Yandex built Clickhouse and ByteDance deployed more than 20K nodes of Clickhouse.

Just like using any technology, we need to figure out what problems we solve for real-time analytics first.

yep. You can fix it for yourself with a SQM-enabled router...

Or encourage your ISP to put in a better packet shaping solution in the first place. There are now a whole bunch of these - Preseem, Cambium, Paraqum, and my own libreqos. Cost is about 30 cents of CAPEX per subscriber.

Now we would have families partially dependent on little Johny and Little Jane's income screeching about unfair grading practices and agitating against hard teachers. These people elect the school board too.

Also yanking more than half the budget destroys everything and nobody gets paid anyway.

In other news part of the cost is to acquire qualified teachers who must be paid more than teachers in Nebraska because they have to be able to live in NYC.

Do you really think most of the budget goes in the bin?

The conclusion is a bit clearer: they think they observed what seemed like zero resistance at the temperature but they are unsure it was actually superconducting, hence the title being the measured resistivity instead of superconductivity directly. It's also possible (and far more likely IMO) them reaching the noise floor of the instrument was not the same as the sample actually having 0 resistance. Superconductors have a sharp dropoff at the critical temperature whereas their sample seemed to just continually have less resistance until the noise floor of the tool.

It'd be cool to find it was superconducting at a temperature near that high though. That'd still be one of the best high temperature superconductors we've found.
who ya gonna believe, me or your lyin' eyes?
The real cost would come in the months after whilst trying to decipher the bill adequately to track down everything you used and get it turned off. (Half a joke.)

I imagine there would be a ton of Lambda and the like in there too.
It would be for me. What kind of measure would you use?
Silver is even more conductive than copper!
Stored in fix, so refrigeration isn't strictly necessary, but out of convention, anything in fix is in a fridge of some sort.

Kids of a certain age get to hold them directly in gloved hands. The place has to have some ventilation, as again, the fixative doesn't smell the best and is also bad for the skin.

Thanks for the questions!

I have tried to produce bufferbloat-related tools that measure things far more accurately and in more detail. https://blog.cerowrt.org/post/flaws_in_flent/
One implication of this is that some time in the future (tough to say when exactly) Wikipedia will have a big attrition problem. I could imagine a scenario in which all the current editors retire or pass away and simply are never replaced and Wikipedia dies.
Absolutely agreed. A corollary to these points has been something I've been coming to terms with for the last 2 years or so, which is the idea of not spreading oneself to thin by continually trying things they're unprepared to commit to; while there are practically endless opportunities for inspiration, consumption, expressing creativity, or learning, it's probable that if they're worthwhile, they require a certain amount of immersion, and it's much easier to be excited about something than it is to shift anything else in your life out of the way to truly involve yourself with a new one. New hobbies and skills have a cost beyond their price.

You're ready to learn to skateboard when you're 10 years old because fitness doesn't really matter, consequences don't really matter, and there's nothing else really competing for your attention. Same with Baldur's Gate. But you're not necessarily empowered to do either, someone else has to buy you the thing to get started.

Later on, you become empowered to buy anything in your budget, but the liar in you pretends that you're actually in a position to learn to do it, even though the value it provides is tenuous at best.

So you buy the skateboard because you've spent 10 years of adult life getting fat and increasing your investments, and today is the day to do something you literally need no other commitments on the calendar for, because you saw your buddy still does from time to time, not realizing that the purchase is the most trivial aspect and actually it'll take 5 hrs a week for a year before your core muscles can even keep you upright. The skateboard goes into storage, and you go back to whatever you've always done.

By appreciating that any given thing takes a lot of work, you can better prepare yourself for the real practice of doing it, and reduce the likelihood that a new prospect will be a flash in the pan. You'll need at least the ability to allocate the time and money, because you'll need reps, and reps take commitment. Reading the book on Postgres internals is very unlikely to be valuable if you haven't ever heard of a database, have no use for one, or aren't a technical person of any kind, and you don't become one by buying it and putting it on your kindle for that one long flight.

That said, it's easy to become too conservative, and you need to figure out when something that you have committed to has declined in significance or is demanding more than it produces in reward, at which time you should start considering what else you might do.
I believe it is the pressure to publish. The number of papers published has grown exponentially and it is reported that the quality of research has decreased.

The premise that two star systems could have some imbalance in goods worth trading is rather shaky. You'd think once you get to interstellar travel energy is the only thing you need.

Based on the terse reply to my question, it seems they really want you to create an account and go through their onboarding tutorial after agreeing to an absolute telephone book sized ToS. Hell, it's possible I'm violating one of the paragraphs by even talking about the process. I appreciate that's likely not what you had in mind, but it seems to be what they have in mind
You could and then sell the extra on the spot market for the other ~1000 days.
Yes, and the Mastadon post came up because it was too obscure.
It all depends on your workload, access patterns, and data model.

You can absolutely spend an arm and a leg making a system work using a RDBMS that would be simpler and cheaper using a NoSQL store. The opposite is also true.

When picking a database you should always consider the trade offs of the different technologies and weigh those against your goals and budgets.

Sometimes is okay to spend more for a system that is just simpler to manage and use. Sometimes it’s not.
What would be better though? 1kg is 1kg, regardless of temperature, pressure and volume. A litre, gallon, cc, all need clarification with respect to something else. You could use moles, but for a given compound, mass is just a more accessible, yet equally accurate, scaled value.
That’s like saying they don’t need ears. It’s a place to see what people are talking about. It’s a place to see how people are talking. It’s a place to gauge responses to certain events. It’s increasingly a place to see news happen before it is shared via any other medium. You go where the people are, you don’t tell them where to go and then get upset when they’re not there.

We've started working on a tool to use CUE to create a single config space across TF, Helm, and other tools in the devops space. We no longer want the pain of HCL or templated Yaml.

Our hypothesis is that a unified config space across our industry will bring many benefits.

Our open questions are largely around whether we

(1) replace / alternative

(2) just a skin, still same reconciliation loop from the tools

(3) replace, but support existing modules & charts
Does anyone think we would have AGI if only we could solve the hallucination problem?
In America it is legal to advocate for Nazism. This is legal and simultaneously a non-threat because our system of checks and balances prevents them from overthrowing the government. They are not denied their first amendment rights, and yet they're abject losers. The US government is simultaneously tolerant of them and not threatened by them.

The supposed paradox of intolerance says that silencing people who would silence you is the only way to prevent yourself from being silenced, but this is demonstrably not true.
I don't know much about AI research but the idea of "measuring" hallucination definitely seems very loaded to me. Humans hallucinate too and I don't think we can measure that. It almost feels like "we need AGI in order to develop AGI".

Route everything to email. Use your email to interact instead.
Ha, I used to write apps for PalmPilot. We showed them to our accountant one time, along with the website, where we had a 'news' page, where we'd post new releases and other stuff.

The accountant instantly commented, "that's exactly what I want. Not a whole website, just somewhere I myself can post a 'news log'". I dismissed the idea, of course why wouldn't you want a whole website, and for news, you use a mailing list where you can send out an email newsletter.

Blogger came out the following year.

China has always been China. Tibet, Cultural Revolution, Tiananmen, Xinjiang. A lot of expats thought they could bury their head in the sand because they had a chance to make money. Same way George HW Bush did.
Thanks, but I knew that, and it does not seem to answer my question, unless I didn't get what you meant.

My question was in reply to the comment above by sbuk, excerpted below:

Why is the argument always "It's less harmful than alcohol..."?

Alcohol is definitely bad. What does marijuana have to do with alcohol?
What other things that are wrong and avoidable (being acts of humans rather than acts of nature) do you advocate just tolerating without even so much as reporting of discussing?

Animals must live with the environment as it is. Humans modify their environment to suit them.

It's ok to be fatalist for yourself. There is no valid reason to try to tell anyone else to be.
Not a great list. Very opinionated, and much as I'm security-conscious, I disagree with a number of "minimum" recommendations there.

This list looks like it was written by people who are not paying for anything, so they don't understand the tradeoffs, costs and compromises. I can assure you things look quite different when you are a solo founder running the business and you have to pay for everything. Technical stuff doesn't change, so recommendations like "Do not limit the permitted characters that can be used in passwords" still hold, but "Contract a security vendor to perform annual, comprehensive penetration tests on your systems"?

Also, "Publish the point of contact for security reports on your website" and "Respond to security reports within a reasonable time frame" — I'm already spending too much time responding to "security researchers" trying to shake me by sending (rather silly and generic) "vulnerability reports". Some of them follow up by asking if they can "publish this on their social media channels" if I don't respond. I really don't need more "security reports" for my website.
Haha true, that's a good point. There's also WAVL and RAVL for weak AVL and relaxed AVL, but no equivalent acronyms for the red-black variants. RRB is the same as Relaxed Radix-Balanced! In my notes I found it easier to avoid acronyms, and then "logarithmic binary search tree" became ambiguous because "aren't they all logarithmic (in height and complexity)?" I found that grouping them as part of the weight-balanced class of trees is the most intuitive, and I wish the original paper did the same, but that's okay.

What I'll do for now is mention specifically that the literature refer to them as LBSTs, and I'll add an index to each tree in the repository to make them easier to navigate. Thanks again.
> In fact, if you asked me to produce a kilogram of hydrogen I don't know what I would do. Is it buoyancy? do you want -1 kilo of the stuff?

Nerd sniped. Atmosphere is 1.2 kg/m^3, hydrogen is 0.090 kg/m^3. So 1 kg of hydrogen at STP would be 11 m^3. The buoyancy force would then be 13kg-1kg.

Accordingly, 1kg of H weighs -12kg.
Update: I admit I'm starting to wonder if this is a core contemporary computer design theory law: Source formats are textual and do not show imagery.

So, I came across some Markdown editors that almost get me there. But I'll probably end up designing my own workflow for limited HTML authoring.

This makes me wonder what a more image-native computer system could be like, where integration of imagery or even video is less of a third-party tooling question...
I honestly struggle to recall a time when there was a windows feature that wasn’t :

* broken on arrival and never really fixed

* negligently implemented that causes serious harm

* a dark pattern that no one actually wants but improves the windows margins through covert means (data harvesting, embedded adware, etc)

I’m sure they exist, but the prevalence of the badness is so striking.
Tankage and sea-surface shipping are both dirt-cheap.
Well, a society that makes deleterious substances illegal is more alive than one that embraces them with open arms. Don't you think?
I don't think you can give an honest reading of those threads and come away with the conclusion that it's just about COVID. Nearly every comment mentioned reasons other than just COVID.

And even the ones that were about COVID weren't really about COVID, they were about the consequences of the totalitarian response laying bare the lack of social contact and waking them up to what was possible. COVID was the trigger but it could have been anything and they know it now, essentially.
Hmm, yeah, you make a compelling argument. Maybe I should stop worrying about problems I can't prevent and just focus on stockpiling ammunition. ;-)
Actually no: they have to be insulated well. People forget that it doesn't actually take energy to stay cool, just to remove the heat. The issue is what's your heat gain from insulation inefficiency per length - and it does get better then thicker your cable gets, because volume increases more rapidly then surface area.
* ROSboard -- visualize ROS topics in the web browser -- https://github.com/dheera/rosboard

Lots of things that could be done with this but a lot of robotics teams and projects got laid in the past year and it doesn't have as many users as it once did. There is also Foxglove which is a full-blown funded startup working on something similar and the more progress they make, the less motivation I have to make my FOSS project better, as a one-person team.

* Air quality monitor -- https://dheera.net/projects/airmonitor/

Unfinished due to the PM2.5 sensor in it (PMSA003I) always reporting 0 and Adafruit not caring.

* BotParty -- telepresence robots -- https://dheera.net/projects/botparty/

Unfinished since COVID isolation ended and telepresence parties aren't needed anymore

* Luxo -- jumping Pixar lamp -- https://dheera.net/projects/luxo/

Unfinished due to lack of time but it does scoot and jump.

* Digital 4x5 camera back -- https://dheera.net/projects/4x5/

Unfinished due to issues with CRA optimization on the microlens array on the Pi HQ camera and unavailability of a real HQ camera with an actually large (e.g. 35mm) sensor.

* E-ink picture frame -- https://dheera.net/projects/einkframe/

Pending to be done: (a) Get rid of the unsightly USB power wire, use a battery or super-capacitor and a thin strip of solar panel on top of the frame, and ESP32 deep sleep mode and have it update once every hour or so. (b) Update it to use a diffusion model in the cloud for image generation (c) Add a microphone and a mode where you can yell a prompt at it and it draws it
Firstly, this is an opinion piece not an article. Secondly, I've never encountered such an inadequate summation of such a notable accomplishment.

If the author holds such admiration for earlier forms of flight, I'd be interested to know how many times he's traveled in a hot air balloon relative to airplane flights.
Yes, I noticed that this article disproportionately quoted American scientists who played relatively minor roles in the replication efforts. I guess the reporter just found it more convenient to reach out to them for comments.
It isn’t new or obscure though.

The details of his false claims of lone inventorship were common enough to be in my primary school in the late 80s/early 90s.

Similarly knowledge that he routinely stole the work of others and presented it as his own is not new.

>I hope people will walk away from this experience with a better understanding of how science works

I don't think this was at all what this saga was about. People essentially turned a physics experiment into social media drama and science had nothing to do with it.

I also don't think the 'academic incentrive structure' has fallen out of alignment with the actual goals of science, despite the fact that people keep saying it, and in particular not in condensed matter physics.

If anything this whole thing showed two things: 1. Science works fine, 2. Please keep it to the actual scientists instead of turning it into yet another discipline dragged on Twitter. I know it's an unfashonable thing to say these days, but 99.9% of people have literally nothing to contribute to a debate about bleeding edge physics research, despite that apparenly everyone feels entitled to have an opinion on it.
Yeah that’s definitely worse.

Although I would note the California case still makes me wonder, as it’s not apples to apples, even if it’s a stupid waste regardless of the actual metric.
