Anyone know what happens if you don't have a device that supports Sidewalk (I have a really old Alexa) but want to opt out for the future? I don't see the Sidewalk option on the Alexa app.
This is surprising. Are we really running out of people who would try run datacenter and an electron App on Apple laptop and then tell us here how these machines are not for professional users.
Would add that HDFS was a particular nightmare to manage.

You had to worry about the size of files since the NameNode would be overloaded. Being a Java app running on the older JVMs it would do a full GC under heavy load and cause failovers. And it was impossible to get data in/out from outside the cluster using third party tools.

I remember many companies seeing S3 and just being in shock that it was so cheap, limitless and that someone else was going to manage it all.
The sad (scary?) part is that one of the two is forever silent.
The part that is less efficient is applying a rotation to a vector (you need to "sandwich multiply" by your quaternion which involves 3×4 + 4×4 = 28 multiplications, whereas with a matrix you only need 3x3 = 9 multiplications).

But composing, interpolating, exponentiating, etc. is a lot nicer with quaternions. (Easier to reason about, numerically better behaved, computationally cheaper.)

If you need to apply the same rotation to a large number of separate vectors, keep your rotation representation as a quaternion internally and convert to a matrix just before vector rotation.
The little lights are probably tiny bits of metal dust or slivers exploding off the walls due to local electrical potentials.
Kairos | UK, Remote | Frontend | Full time

Kairos sports are looking for entry level and senior frontend developers.

A bit about Kairos:

Kairos is a platform for professional sports clubs to streamline planning, communications and optimise athlete performance. Kairos has progressed from initial trials and is now being used by national teams at the highest levels of sport in Europe and the US including teams in the top four tiers of English football as well as Premiership and Pro-14 rugby union teams.

We are looking for people with a strong desire to learn, a relentless focus on product and great written communication.

You don't need to be excited about sports (but it would help) but you definitely do need to be excited about creating great experiences for our customers.

We use Typescript, React, GraphQL and React Native. Specific knowledge of these is helpful but not required.

You will be working as part of our small team (the entire company is <10 people) to take full responsibility for the whole lifecycle of a feature from design, implementation testing and deployment.

We have both a mobile app and a web app. You would be working on both.

We value and encourage positive intent, teamwork, a no-blame culture, patience and an agile and efficient mindset. Supporting teammates & mentorship is a big part of how we work.

Our interview process is:
- A quick conversations with me to talk about some of your experience and a chance for you to ask any questions about Kairos
- A short take home assignment
- A final interview with our CEO

These are "remote first" positions, although we have offices in Belfast as an option.

If you have any other questions you can reach me at dean.merchant@kairostech.io
When the US and Soviet Union established MAD the prevailing method of fighting wars was to fire/drop/shoot as many low-accuracy munitions as possible at the enemy. More ordinance was expended in the Korean war than in WW2, and by the Vietnam war planners had to moderate B-52 carpet bombing as 12x B-52s carry nearly a nukes worth of ordinance. North Korea lost roughly ~20% of its population in a conventional war.

It's easy to justify nuclear escalation when fighting this form of total war, and difficult to when the only casualties are military and the bombs mostly fall on equipment. While a land invasion or surprise strike of the continental US/EU/China/Russia would surely trigger a nuclear response, a direct battle over territories/international policy wouldn't be as clear cut.
Maybe you could cross compile on both systems and see if it actually does make a difference. I'm doubting it but don't have much to base that on.

Hi,
I had some great fun coding all the effects in this video using python, opencv and dlib.

My approach:
I work as a dev in roboto nautic drones. I am strict at the dayjob so i "shitcode" my "artware" in my sparetime meaning i usually go through the following cycle:

(Example based on the slitscan teeth and eyes effect from the video)

1. I wake up from a (day/night)-dream with a thought: "how wluld it look if the teeth grew out from a video face while showing their past as a slitscan"

2. I find a sourcevideo since i am lazy (usually on youtube)

3. Load up vscode and startwriting python

4. I write in a state of garbage flow, garbage because the code i write is deliberatley trashy (a vent/dayjob escape), flow because i dont do much editing. Itend to like to overwrite (reclare) functions instead of correcting them leaving a huge pile of trash code

3. I render a few frames, correct my algorithm, render some more and when happy (or falling asleep) i press enter and let it run (with tqdm telling me eta on completion)

4. I way, usually days because i deliberatelydont optimize my code so its slooooooow to render

5. On finnish i look at the result and feel like i got the answer and move on.

In this example though i didnt move on cuz i was doing a friend a favor and had to compile my messy clips into a timeline and give it back to him in form of a music video.

I canrelease my shitty code but i am afraidsomebody might get a seazure looking at it lol
I have yet to find a single study confirming any rumored ill effects of artificial sweeteners, including aspartame. At least in any reasonable consumption amounts since you need so little of the sweetener.
Wow that seems like a significant feature. I'm surprised it is not mentioned in the release notes: https://github.com/obsproject/obs-studio/releases/tag/27.0.0

Reading Europeans' comments on threads like this leaves me wondering who is more ignorant about America, me (as an American...) or them.

I don't know anyone who goes out drinking to get drunk. I know people who socialize with friends and drink alcohol while doing it. I know some people who have a glass of wine or two with dinner. I myself drink a couple microbrews once a week with friends.

But what I'm getting from our European friends is that everyone they know from America is an alcoholic.
Yeah, I think since we're talking a 10-20 year time frame, they are vastly overlooking less obvious things like investing in the next generation in a broad way, rather than these tactical goals relating to theoretical conflicts.

But setting these agenda items are not the responsibility of the Military. Congress should be deciding where the money goes, and they should actually get around to infrastructure and education spending that will allow the next generation to be more effective.
Having lived in the UK and the US, I firmly disagree. I had never seen drinking at the extreme levels until I went to the UK.

I seriously doubt the entire articles premise that somehow alcohol binging is unique to the US. There are a lot of counties with a lot of forms of alcohol out there…
High-level, we wanted to minimize the need to "jump around" to multiple files or multiple places in a file to make a single change to an action (and also just minimizing the amount of boilerplate generally).

If I'm remembering, createSlice() got us most of the way, but async actions still needed an extra declaration (and maybe types? we were using TypeScript), which couldn't be placed next to the createSlice reducers, since they're in-lined. I can't remember if we ended up popping the reducers out into their own functions so they could be next to the createAsyncThunk call, or if that created too much of a typing headache and we just dealt with having async action creators declared at the top. (We also tried just using createReducer directly, but iirc the typing was just extra work compared with createSlice.)

**

Only partially-related to RTK, but the other thing we had to tinker with a bunch was performance. RTKs default use of immer helped a lot, and I believe we also ended up using createSelector (or perhaps the Reselect API directly) in a few places. We also had to learn to make extensive use React.memo and React.PureComponent. Redux dev tools were incredibly helpful for figuring all of this out.

*

Anyway, hope that's useful/interesting! RTK made a big impact in my day-to-day React/Redux development, from "ugh so much boilerplate I feel stuck" to "I can make changes reasonably quickly." Hope to see it continue to improve!
There's really no exceptionalism when it comes to America's so-called drinking problem. Having worked at an alcoholic beverage MNC, it's pretty clear that every country has its own subculture of getting hammered. I'd even hazard the hot take that America is rather middle-of-the-road when it comes to binge drinking (certainly by per capita consumption is not exceptional).
> "Consider what happens to a soul which always gets what it wants."

In a popular Alan Watts talk he imagines a dreamer:

"let’s suppose that you were able every night to dream any dream you wanted to dream, and that you could, for example, have the power within one night to dream 75 years of time, or any length of time you wanted to have.

And you would, naturally, as you began on this adventure of dreams, you would fulfill all your wishes. You would have every kind of pleasure you could conceive. And after several nights of 75 years of total pleasure each you would say “Well that was pretty great. But now let’s have a surprise, let’s have a dream which isn’t under control, where something is gonna happen to me that I don’t know what it's gonna be."

And you would dig that and would come out of that and you would say “Wow that was a close shave, wasn’t it?”. Then you would get more and more adventurous and you would make further- and further-out gambles what you would dream. And finally, you would dream where you are now. You would dream the dream of living the life that you are actually living today."

True but this is addressed in the article. If what you need is code that runs on a RPi, this is a meaningful comparison.
One point to add to all of the great points here is consider getting a smaller keyboard (or an ergodox) especially if you're on the smaller side (for the same reason as the last point, stretching less tends to be nicer on the tendons).
Connection scaling in postgres works better with the more recent versions. Still, you might indeed want to implement a connection pool for your PG instance if you have large swathes of mostly idle connections due to the single-backend-per-connection constraint of postgresql.

Not MySQL itself but something like Vitess [1]. I believe MySQL 9.0 should be close.

I think the US is a land of "extreme" personalities so I would guess that across a broad range of metrics (alcohol consumption, wealth, number of text messages sent per month), the ratio of the Top 1% to the median is probably higher in the US than in most other countries that the US considers "peers" (i.e. Western Europe, Australia, and Canada).

It is very easy to point out, with hindsight, what the seminal moments that change the nature of warfare are. It is not so easy to point them out when they are occurring right now. Furthermore, it's always going to be the case that people will promise that their shiny new technology will be the one that makes all existing battleplans obsolete and is unstoppable, etc., etc. Only rarely are they right, and in historiographical terms, we tend to only remember the people who were right and not those who were wrong.

A good example of people betting wrongly on new technology is air power, or specifically, strategic bombing. Early air power theorists (we're talking the 1920s here) made the case that once you start lobbing some bombs at civilian targets, you'd so shatter the morale of the target country that it would collapse in a few weeks--a few months, tops. When WW2 came about, both sides indeed attempted to end the war via bombing the other side's civilians into oblivion. And both times, it failed miserably. Even the US Strategic Bombing Survey struggled to find examples where it came close to achieving its goals, hardly a ringing endorsement of the concept.
Bird brains, such as parrot and crows so that brain size is not everything. A crows brain is smaller than a chimps in overall size and body:brain ratio, yet crows show more complex social behavior, problem solving and tool use (despite not having hands). Bird's brains are much denser than mammals, so it's less size and more number of neurons, and the complexity of how these neurons are networked.

One could see this in action in the Hellwig vs VMWare court case (one of the few GPL court cases).

As a first step they had to show that Hellwig had made changes to code that VMWare uses that can be copyrighted. Especially difficult since every line in Linux is modified by a few different people. They failed at that and that ended the lawsuit if I remember correctly.
It was such an obvious missing feature. Though to be fair, implementing undo/redo functionality is often nontrivial.

However, there's still no way to save/export scenes, aside from simply copying your entire app data directory. I just have a basic layout with few tweaks so it's not the worst thing ever, but for any streamer with a complex setup and carefully adjusted filters, moving to a new computer or whatever must be an enormous pain point.
Well general and specific, and short- and long-term, are orthogonal. Oil is also generally necessary in the US economy in the short-term, if (conceivably) not in the long-term. On the other hand electricity is not necessary in the short-term specifically to aluminum foundries, but in the long-term it is (or the crucibles solidify).
This article is not that clear (there is no frequency shift occuring). As others say, the authors are using speckle imagery, which relies on the wavevector of the illuminating beam (rather than the frequency). By adding the hyperbolic metamaterial the authors can access wavevectors beyond the diffraction limit, so that once they do the appropriate prost processing achieve super resolution imagery.

It's not directly related but reciprocal space and Fourier imaging is quite interesting for those that are not aware of it (such as estimating the size of a crystal lattice by looking at the diffraction pattern)

If you are interested in multiple dispatch, you really should check out Julia. In my opinion, the biggest reason Julia has been as successful as it has is that everything uses multiple dispatch, and the system for it is simple enough that you might not notice.

You are absolutely right about the footguns, legacy cruft, and the joke-not-a-joke-it's-so-stupid that is modern web software development. That all needs to be fixed, and here at home

However, it is also not merely about the Whoppers running out - this is just this morning's example.

When even major "security" vendors can be turned into serious NatSec attack vectors, and much more critical infrastructure can also be attacked with ease, and they are doing it, it becomes a bona-fide NatSec issue.

Like any other NatSec issue, this requires both serious hardening actions at home, and serious threats against bad actors abroad. Whether that involves, some kind of diplomacy, economic sanctions, targeted software attacks, targeted covert actions, or overt drone strikes, is up to the experts in those domains, but we do need to treat this as a serious NatSec issue that it is.
Natural selection means that they likely are warlike and violent. Warlike and violent intelligent species destroy themselves quickly so are unlikely to exist at the same time as us.

Only the ones that can reengineer themselves to not be warlike and violent before they destroy themselves will survive for long enough to exist at the same time as us. Therefore it is likely any intelligent species we meet will be peaceful (among themselves at least).
Fair enough. I think the main takeaway is that photographic gear is now so dirt cheap that branding and really high end gear only matters to the pros, everybody else could just use their phone. That won't stop a whole bunch of them from buying stuff they don't need, but that's fine, it brings the price down for the professionals.
I'm sure it just varies a ton from person to person. As much as some people (notably alcoholics) find it extremely difficult to stop drinking, I pretty much stopped without even trying. Got married, had kids, stopped hanging out so much with friends. I just didn't drink for months at a time and didn't really notice. I never consciously quit drinking, but I average maybe 2 drinks a month now and don't miss it. I also never really found that alcohol really relaxed me emotionally.

Re the last link, as long as an archive only exists in a single place or is only operated by a single entity, it may as well not exist at all, because eventually it won’t. (This is also what terrifies me about the Wayback Machine and, to a much lesser extent, WinWorld.) An archivist who does not provide for easy mirroring is thus irresponsible.
I complain about how hot the i9 gets... but then I remember the period where Apple was transitioning from G4/G5 to Intel Core 2 Duo chips... in both cases they were _searing_ hot in laptops, and Apple's always fought the battle to keep their laptops thin while sometimes sacrificing anything touching the skin of the laptop (unlike most PC vendors, who are happier adding 10+mm of height to fit in more heat sinks and fans!).
You can return it (within 30 days) and get the new generation. I am gonna upgrade my 16" MBP Intel i9 as soon as I can buy the Apple Silicon in 16".
Just for another perspective I have GERD spurred on by a hiatal hernia and don’t experience nausea this way after drinking. I only really get nauseous if I drink to excess.
It's called "walled garden" actually.
Mine came from feeling like junk even after 1 beer/wine/cocktail the next day. I experimented with thinking it was an allergy to grains, allergy to hops, wine quality - but I think it's just alcohol.
Not for production, but used it for deployments to remote servers via SSH using GitHub Actions. Wrote a guide and video tutorial of how to as well, it uses nginx proxy and surprisingly updates were zero down time since the nginx proxy didn’t change and handles switching app ports seamlessly. For low traffic app could be used for production but I wouldn’t since it is a single server deployment setup. Good for dev/test environment, I use this pattern for 20+ live demo apps on a single server.

yup. I ferment craft soda in my cellar. root beer, ginger beer, cream soda, and I have to be careful or it starts to get a noticeable alcohol content. most of my friends drink when we get together and I am not fond of the flavor of beer. But home brew ginger beer seems to fill the space and I can drive home after as the sodas when done properly have like 1% or less abv. just have to pasteurize it at the right point or drink it soon enough.

In particular, that toggle switch to show it in terms of an angle makes it super clear.

The 4 components can be re-written in terms of 3 variables for an orientation vector and 1 variable for rotation about that axis. Basically "point this way and rotate this much". The 4 variables are expressed as two complex numbers.

That helped me understand what the quaternions are actually describing. Incidentally, it also kind of explains why 3 variables isn't enough, and so the regular rotation thing must not be sufficient.

But how much does a sleep study cost? Specialize doctors, specialized lab, specialized equipment: $700-$3000.

I got a better deal with my work's insurance plan: it would bill me for it if I didn't use it, and auto logged the data for me. That sounds ridiculous. Also my sleep study was just a unit I wore at home in my own bed. Seems cheaper than an in erson sleep study
