>Take an audience of X people. Divide them in two. Show ads to your test group, don't show to control. Watch your business grow and gauge the lift between the two audiences.

How are you measuring the group you don't show ads to?

This is exactly the sort of experiment that the economists in this article (both independent and from Facebook) did, and measured substantial selection effects.

The fact that there are businesses built on businesses built on businesses that are, essentially, allowing people to compete for tiny ad space on specific keywords demonstrates that there is too much hype and obscurity in the space.
Agreed. I recall rescuing a 5000 series CPU board from some systems being retired. The boards had originally cost ~50K GBP each and consisted of four seperate 12" x 16" boards bolted together in a 3" thick stack. The boards had several MCUs including M68k plus lots of 74series logic chips (numbers approximate - it was a long time ago).
I am not sure what point you are trying to prove. All this stuff came from outside the regular military. So in the present you should be more worried about militias taking over than the regular military.

Local HOAs and similar have loud voices against these kind of projects. It might take another big voice (like Sidewalk Labs) to counter.

I've tried calling my local reps to support walkable community projects and have been told, nearly verbatim, that if the HOA doesn't like it, they won't be voting for it. Then when big tech offices started moving in, the redevelopment projects finally started too.
Information theory
As a fan of the "Millennium" Swedish TV miniseries, with a fantastic Noomi Rapace as the original Girl with the Dragon Tattoo[a], I found this piece fascinating.

I knew very little about "Scandinavian Noir," and in fact didn't even think of it as a genre until reading the OP.

Now, I want to read the "Beck" novels and also watch its Swedish TV/film adaptions, if there are any.

--

[a] https://en.wikipedia.org/wiki/Millennium_(miniseries)
-- In my humble opionion, the Swedish TV adaptations of Stieg Larsson's books are much better than the Hollywood movie adaptations, which tend to be much flashier and have more special effects but don't feel or bite quite as hard as the Swedish TV miniseries.
I would dispute that those common patterns are indeed safe, even if they could be argued they are when first written because code changes and can suddenly break your preconditions if they aren't enforced in the code itself.

C codebases then follow certain defensive programming customs to avoid reading uninitialized or out of bounds memory, at the cost of some performance. This is the right trade-off in C but, funnily enough, the more restrictive borrow checker has the opposite effect as you can give out inmutable and mutable references with wanton abandon because they get checked for unsafe behavior. It's the same difference as a a gun where the best practice is to keep it unchambered at all times to avoid the risk of a misfire, and a more modern gun with a safety: it's one more thing to think about but it actually smoothes the operation.
Yes, and I've clarified and fixed my originally badly described wording. I'll let Zoom describe this themselves.

From Zoom's S-1 [1]:

"In addition, we have a high concentration of research and development personnel in China, which could expose us to market scrutiny regarding the integrity of our solution or data security features. Any security compromise in our industry, whether actual or perceived, could harm our reputation, erode confidence in the effectiveness of our security measures, negatively affect our ability to attract new customers and hosts, cause existing customers to elect not to renew their subscriptions or subject us to third-party lawsuits, regulatory fines or other action or liability, which could harm our business."

I hope all the positive replies here are from those who actually used Zerodha themselves over a period of time. When I tried it last year, the website was buggy and even saw HTML errors in response. I moved away to a traditional broker as a result of that.
I think a key difference here is fully open and collaborative specs, with Apache-licensed reference implementations for server and client that they dogfood themselves. It's also getting federated. So protocol, tech and network can live on regardless of who's running the servers people are using or driving the development of implementations.
I have moved much of my digital life to Keybase. This news brings me much fear but I just pray that Zoom takes the best parts and then allows Keybase to continue to function as a goodwill venture at least until a suitable replacement appears. The software package Keybase offers is unbeatable.

Open source software is (I would argue) even more driven to fragmentation by political, ideological, and personality conflict driven squabbles than proprietary software, as there is no profit motive to also satisfy.

Also, the broken window thing asserts that small amounts of criminal activity lead to larger amounts of criminal activity via signaling that being bad or neglectful is OK, which is both not proven and irrelevant to software writers being prone to reinvent the wheel for whatever reasons they have.
IIRC: In the late-2019 BBC Click interview with GCHQ on the subject of Huawei, 5G, and security the spokesperson said information security wasn't an issue as we have end-to-end to handle that, the greatest risk was remote shutdown of the network. I assumed they're alluding to "in a time of war", falling back to non-5G wouldn't seem to be a big problem ... but then lots of our comms send to run on Huawei hardware already.

Personally I don't think that risk is worth avoiding Huawei over. But then I'd be happy to maintain the top level of infrastructure we already have in the UK and work on bringing breadth to the networks using 3G&4G and taking an upgrade-hiatus. I'm not convinced the average person will get much from 5G except more infringement of civil liberties ...?

The human cost of building those factories, and maintaining them, is 1% of what the hand labor used to be.

Yes points to you for noticing there's a supply chain. But that's automating too.

The remaining 'developers' in industry are Engineers. They number a tiny fraction of the human labor that factories used to employ. The idea the we can 'retrain' line workers is nonsense. They can't all become Engineers, even if we needed 30M more Engineers which we don't.

Grasp at straws, sure some business processes might remain unautomated for some time. But it's not going to matter to most Americans. It'll be small change.

Yes the number of Qubits used to represent the problem scales polynomially with the bit-length of the input integers.

However, annealing here is used as an approximation of a brute-force search. If you demand a sufficiently exact (i.e. non-approximate) result, run-time is still going to grow exponentially with problem-size, thus for 2048-bit numbers the D-Wave machine will maybe not finish by the time the universe ends :)

One thing which could also help would be a "Netflix for news" given the pain points for payment and economies of scale. The tech scale mixing is beautiful in that way in that big providers and small can both be provided to the end user and revenue apportioned based on usage.

Of course the newspapers have been in need of reform for a long time now on many levels. Not helping is Associated Press recycling of stories across many different papers which leads to trying to compete as distributors instead of content providers. Consolidation of conglomerates seem to have only doubled down on lack of quality.
I've done something similar. At the side of the house I had a patch of around 50m^2 (I think...). Last year in spring I sowed a bunch of wildflower seeds bought from a local garden supplies store. It already bloomed quite nicely last summer but this spring it has already turned into an explosion of colorful flowers.

Also doesn't require much maintenance so far (which was one of the goals for that patch :) ). Before sowing it last spring I had it covered up for the winter with this tarp that still allows water through, after carefully removing all the weeds and plowing it in the fall.
This year, as spring was slowing setting on, I removed the bigger pieces of dead material and sowed some extra seeds on bald spots. Still waiting if that is taking hold.

I'm pretty happy with how it turned out so far, as are the (humble)bees, butterflies, ...
There exists a fundamental level of electrical noise at all frequencies typically controlled by the background temperature that sets the minimum level of signal you can resolve before it gets washed out in noise. GPS uses multiple coherent (noise being random instead of coherent does not combine at the same rate) copies of the signal that can be recombined to increase their effective signal, so even though they are transmitted below the universal noise floor, they are above it once recombined.

For testing, are you suggesting we should execute 300+ million tests within a very short window (like a few days short window), and then quarantine the sick? Do you believe we have the testing resources to accomplish that? Do you believe we can lock our borders down tight enough to not let more infection in? How will you manage to execute such tests without getting everyone to gather in big testing facilities which will surely infect some of the people who tested negative? Try to play out the logistics of this in your mind for how we'd really accomplish this in the real world. It's not real any time soon.

The absolute best case scenario by Fauci for a vaccine was 1 year. Let's assume even that miracle occurs. Do you really believe shutting down the economy for a year is feasible without a collapse of civilization as we know it? Then you have the same logistical problem of making and delivering this vaccine to literally billions of people. It's technically doable, but not in any kind of short time frame. I'm sorry, but it's just not real, and it never was.

Sure, but that's still the free market. Free-market purists (many of whom live in rural areas) have to realize that this is what comes from taking a hardline stance against government action when it comes to the economy. Stuff just shifts to maximize efficiency, with no regard to the lives that break in the process. This is the unregulated force that they so blindly worship.

Oh, this study was very useful, no matter how the guardian is trying to frame it. There was no clear indication that basic income encourages people to find jobs. You can scratch that one off the list.

Other than that, there's absolutely nothing surprising. You give people a money and they feel better. That's like... not exactly new information. And yeah, it will change their choices somewhat, which again is no big find.

There was a pretty big and important hypothesis that the study was trying to pin down: is UBI profitable? Do you give 500 EUR and get more back? The question is very reasonable and there was quite a bit of clamor for exactly this kind of pilot study to get details. Quite a few mechanisms could potentially get us there - for example people could focus on training for a better position. Or simply having more time to look for jobs they'd find better matches. And so on.

And the answer is: there is no trace of that.

Sure, we do need better studies, longer durations, higher amounts, more people. It's definitely something that's worth studying. But the gold standard so far, the linked study, found nothing in this direction. That's a big negative, and well worth noting - not hiding it into a bunch of "people feel better with more money" like this article is trying to do.

Very usable. Felt very well made as well to be honest and i felt that typing longer notes/emails was much less tedious than on a soft keyboard. Personally, despite a soft keyboard with swype etc being faster, i get a mental fatigue doing anything long that needed lots of editing which i didn't on the Keyone black.

Very clever feature is you could swipe on the keyboard to move the cursor as well.

Also you can set up keyboard shortcuts to press/long press to open an app/perform action when on home screen. Hub software excellent also.

I've just released my first SwiftUI app (only) on the App Store
It happened today! I just tried to open a new tab to look something up but the page comes up with this:

> Sorry. We just need to do one small thing to keep going.

> Firefox has just been updated in the background. Click Restart Firefox to complete the update.

> We will restore all your pages, windows and tabs afterwards, so you can be on your way quickly.

I was in the middle of something. I had a thought, a question occurred, and I
wanted to look something up on the Internet real quick. So I hit ctrl-t for a
new tab. But that isn't the "new tab" command right now. Firefox has entered
into an invisible quasi-mode that remaps ctrl-t to "restart firefox". But
not quite. It actually remaps to a command that locks firefox like a grab:
it's unusable, it refuses to load and display any more pages until I
click that "Restart Firefox" button.

Interrupting my flow by remapping keyboard shortcuts to non-dismiss-able
modal dialog with one button ("Click here and only here you idiot monkey" is what that says to me) is super-arrogant. It's patronizing and disrespectful. Saying "sorry" before you shove me doesn't make it any better, it just sounds obsequious.

I switched to Vivaldi yesterday. (The opening-a-tab thing today that I'm currently bitching about was to find something in my old history in FF.) I don't actually like it any better but it hasn't spat in my face so far.
Keybase packed together many different technologies in one place. I don't think any of us who moved to Keybase had delusions that it would be around forever. But it's an amazingly comprehensive suite for its small scope and the open source product that replaces it will only exist because Keybase existed.

If the writing is placed on the wall (the marker cap is open right now) then replacing each of Keybase's features with existing technologies won't be difficult -- just time consuming, which is why they have market fit.
You can optionally have Keybase (generate and) store your private key for you.

It's designed to lower the barrier to entry, but is obviously less secure than managing it yourself outside of Keybase (e.g. in GPG keyring, or a physical OpenPGP smartcard such as a Yubikey) - and some consequently wish the storage had never even been offered.
