KJ Magnetics is an interesting example of driving traffic for online shopping.

I could buy similar products on amazon, but since I'm occasionally there reading the interesting blog, its kinda my first choice.

Also another common amazon problem is poorly proofread unprofessional ad copy. Like if they can't bother translating full specs into English, I don't feel they can be bothered to properly ship on time. So the attention to detail and high quality details in the ad copy also drive sales above and beyond typical amazon.

They could use amazon as a back end fulfillment platform, but the amazon web UI and amazon search engine just don't cut it compared to the KJ online store. Its an interesting alternative strategy to observe in the era of "all retail purchases will inevitably eventually move to Amazon". Someday, in theory, the amazon UI could encompass these features and adsorb all this traffic and commerce, but its not happening yet. Working the opposite direction places like McMaster Carr and MSC and similar have been pushing downward from corporate B2B only to semi-retail sales.
Every time this CEO is brought out and beaten up I feel compelled to come to his defense. I used to visit JCPenney when I lived in a small city and I was frustrated by the products that felt overpriced for the coupons to later mark down. I had to wait to buy a shirt until the sale went on, and sometimes it meant I searched and bought elsewhere. When this new method arrived I was excited to know that I never had to worry if the price was going to get better or be horrible from week to week, so I could buy on my own terms and not feel cheated.

After the CEO was fired and the prices went back to the seesawing coupon schedule, I quit going and moved on to something else. He had a good idea. I will miss the no-nonsense pricing.

>On the other hand I'm also learning Russian and Anki just doesn't work. Words won't stick in my head the way they do with German.

Because (for English speakers) Russian is harder than German. You need to reduce the number of words learned per day. Japanese is even harder to learn, but you have to be persistent. I spent more than an hour every single day for several years straight to learn the vocabulary.

Also there's a unique challenge with Russian is that nouns, verbs and adjectives are all conjugated, and the rules are quite complex. The noun cases would be completely foreign to non-Slavic language speaker. Even if you learn the vocabulary, using it in sentences is not trivial at all.
What Is Drauger OS?
Nice idea and all the best of luck to the team, but if experience has taught me anything, it's that the staging topic is extremely hard, mostly due to conflicting requirements.

On one hand, what you want is as much prod/stage parity as possible, however there are often various side concerns that go against the ideal of "isolated, but equal".

Just from the past few years, I can remember dozens of instances where "easy" staging wasn't an option. Staging services actually needing access to various levels of (partly anonymized) prod data, partly read-only, partly local. Deactivating caching on stage for better testing. Separating or smartly accessing cookie domains from others. Databases that are far too heavy to keep a second set of (especially data warehouses).

In the end, "staging" for me is a problem class that I don't see anyone "solving" in the way "dependencies" won't ever be solved, but I'd be super happy to be proven wrong.
Looks great! I have a few questions.

- I have a huge Zettelkasten note archive (I manage it through Sublime-Zk, which is getting a bit slow to operate it). Can I somehow directly import all my Zettel notes?

- I tried to import my Anki cards, but it seems like while I could go through them, I couldn't assign them to any particular deck/reclassify them. They show up as part of a "Not Found" deck and I don't see any option/drag-and-drop method to move them anywhere else.

I'll definitely be giving Mochi a try. Thanks a lot for creating it!
I think the childish design serves another purpose: to make the user feel safe about how their data is stored and used (whether this is justified or not).

The Americans are currently getting a worked example of how a billionaire spending their money on advertising can ensure voters know who they are but those voters might still say "Oh that guy, he's fucking awful, No".
If you're using gitflow, you've got a separate develop branch that everybody merges to, while master remains stable. Only when develop works and passes its tests, can it be merged to master.

And with multiple teams sharing the same code base, breaking master is going to slow a lot of people down a lot more.

I have little experience with multiple teams working on a single code base, but it sounds like a recipe for disaster no matter how you organise that. Make your code as modular as possible, so each team can take responsibility for their own code.

Well, as a counterpoint, imagine how much time could be saved if you were able to recall from memory not just the most-used functions that you need for a problem, but the next level down of sometimes or rarely used ones. Or for patterns, or for other such things that can be simplified down into memorizable / recallable blocks.

Regularly looking things up is ok, but actively re-experiencing the thing you're trying to learn is a better way to make it stick.
> In today’s world, the physical store can no longer compete with the web’s infinite selection, but can still offer value in curation and presentation.

Could not agree more. I always feel like I'm taking a risk when ordering an item from Amazon, but never feel that way when shopping at say, Costco. I trust Costco's buyers to curate and vet the quality of a product for me.

I'm still using Meld since I switched to Windows from Linux. It's not a quite a native UI but close enough. I was surprised to find it is written in Python. It uses GTK for UI. It's worth looking into. I know I am.
Clearview now says the app is "available only for law enforcement agencies and select security professionals to use as an investigative tool."

I'm fairly convinced by David Brin's argument that this is exactly the wrong approach. In The Transparent Society he argues that privacy is no longer an option; our choice is between a society where the police surveil us all, and one where we all surveil each other. He says only the latter is compatible with freedom. We have to be able to monitor the cops and the powerful, just like they monitor us.

Maybe we need our own Clearview, with open source face recognition and data on the darknet.

> GA ... which isn't a 3rd-party tracker.

Why not? It's not self-hosted and results are stored elsewhere.
The problem is you are charging more without providing a clear case that the value is worth it. It looks like a bad deal from an existing customers view point.

73/month is not a lot, but it’s still turning back on the original value proposition. If it’s such a small amount, absorb the cost as cost of doing business, so you can retain customers better and grow new ones.
> Yes, Climate Change Did Influence Australia’s Unprecedented Bushfires (scientificamerican.com)

THIS is a good example of why people don't trust scientists or global warming.

The narky Yes, is based on a pre-print, this isn't even published, I assume not peer reviewed yet. Good to see even the journals no long believe in peer review which they base their authority on.

The first paragraph has NOTHING to do with the study, but lets toss it in with no scientific backing.

> Such an extreme fire season is at least 30 percent more likely because of global warming

And 30% more means the 3 in a 100 year event now happens 4 times every 100 years. Which is not great but not scary either. It's still something we 100% have to mange and deal with, which we can.

Scientific American needs to scare people to get their clicks, and they are misrepresenting numbers to do that. This is not how to do real science.

This is the most beautiful neutral-yet-poignant description of a bookstore clerk I have ever read. I'm still laughing about it.
Trying to build synchronous out of asynchronous requires state machines, buffering, and overallocation of resources. It’s the enemy of scale.

The two styles are an impedance mismatch.
Will look forward to it too, if we'll ever see it.

Traffic control if a big part of the problem, if not a half of it.

If you had 100% pedestrian free roads, with ideal road surface, and radio signalling, where a car becomes indistinguishable from a train for control purposes, then even with current state of computer science it becomes quite real.

This is the route most Chinese companies are progressing on. They are not making a self-driving car, but a "self-driving road." Something akin to air traffic control system for cars.

And this is only for things like public transport, garbage dumpsters, cleaning, and other public utility vehicles.

The bus gets a radionavigation receiver, radar for collision avoidance backup, and receives commends over the air.

The first one sells for $20k. The second one sells for $200k. The third one sets a worldwide auction record.

Just as plausible given the motives of art buyers.
Yeah, unless discounting turns itself into auto-parody, check Udemy - all courses cost $200, but, hey, for new users for only 60 hours there is 95% discount. It doesn't take much time to realize that this discount is always there. What's the point of that?
They exist and you can get them at Walmart, Family Dollar, and other bargain-basement stores. They are at that price point because the prepaid carrier (usually TracFone or similar) expects the buyer to purchase blocks of "minutes" and "megabytes" to use with the phone. It's basically a loss leader.

Winters are shorter and summers longer in Australia compared to 70 years ago:

https://www.bbc.com/news/world-australia-51697803

This means a reduction in the length of the cooler stable weather periods when prescribed burns are able to be performed:

https://www.dpaw.wa.gov.au/management/fire/prescribed-burnin...

So the opportunities when the weather is "just right" for conducting a fuel reduction burn are fewer. Various regional fire departments have stated they are not able to complete their planned burns as a result.

https://www.afr.com/politics/federal/hazard-reduction-may-be...

Not risking a prescribed burn getting out of control due to unfavorable weather conditions doesn't sound like shitty forest management policy.

Another factor leading to fuel load build up is the decimation of native wild life like quendas and woylies due to predation by feral cats, dogs and foxes:

https://www.abc.net.au/news/2018-07-06/quenda-poo-helps-tree...

These small marsupials eat the leaves or dig the leaf litter into the soil while foraging. This reduces the build up of dry leaves on the ground and thus reduces the fuel load.
I've overhead cafe managers talking about how much of the store's sales are from the cafe. You can't build a 20,000 square feet Starbucks and be competitive.

That really is the draw, though - making B&N a place to hang out. People spend hours there at a time.
> Compilers, or more specifically buggy optimization passes, assume that floating point numbers can be treated as a field – you know, associativity, distributivity, the works.

Of course, this largely depends on how "YOLO" your compiler is. I believe GCC and Clang try reasonably hard to follow IEEE 754, which ICC is much more lax.
I'll be glad to see the end of "bestseller" (that nobody wants) push-marketing.
I guess the standard discounting approach means that people who care a lot about low prices can get even lower prices, because to they are to an extent cross-subsidised by people that don't care.

In the always-low-prices model, no cross-subsidy is available, so you lose a lot of the people who care about low prices, and you don't gain many of the people who don't care because, well, they don't care.

I think you'd be able to learn the Greek alphabet in at most an hour, just by writing it out and saying it repeatedly. Making it stick long term would be a matter of a couple of minutes a day for a week or so, then every few days. It's small and simple enough that flash cards aren't necessary.

For more involved facts, Anki seems great in principle, but in practice I've found it hard to create and maintain the habit of doing the cards.

I think an ideal clearing style would have the resulting shell prompt as an element of the animation. Let's say you've get the matrix digital rain, which resolves into just the prompt "raining" and then resolving into the regular text.
Or just the prompt easing/fading in after the main loop.

But yes, most of the animations are quite a bit too long. I wouldn't mind a quick Star Wars diagonal wipe, though, to be honest.

> average annual return of 350%

That's misleading. The price is currently at the ~35-40% retrace from the high of 20k. What happened so far (for example the rally to 20k) is not an indicator that Bitcoin's value will grow or even be sustained.

I'm not saying Bitcoin doesn't have speculative value, but you have to be already an experienced analyst and trader (in case of day trading) to have a chance at profiting from it. "If it were easy everyone would be doing it" proverb is true. Crypto is much harder than forex for example. Again, unless you really know what you're doing, trading will hardly be more profitable than going to the casino.

In many cases less time that what I spend looking it up. I regularly look up things I haven't needed before, a few minutes of reading and I know it. Many of those things are something I expect to never need again in my lifetime. The few seconds to memorize all those things is greater than the time saved. Particularly since I don't know what I will need next week and so I'll be spending a lot of time learning things I turn out to never need.
No, I don't think that's accurate. In the scenario you pose, sticking and switching have an equal reward, so both are valid solutions.

wow their UX is atrocious.

* Download page doesn't explain why there are 3 packages and which you need

* On installing first & clicking next it pins all CPU cores to 100%

* The package that presumably controls this silently fails to install - on a brand new up to date ubuntu install.

...so now I'm stuck with a service pinning everything to 100% (while in use) and no way to control it. Uninstalled.

I'll stick to BOINC.

There's no practical reason to limit autonomous vehicles to human-visible signals. The point is to make a car that drives safer than a human. Since we can't make a car that's smarter than a human, we can at least even the odds and make it see much better.
I notice that some people seem to care more about pretty history than about useful history. I'm not a big fan of rebasing for this very reason: it changes history, which can misinform about what was really done. It can introduce bugs in commits that didn't initially contain them.

Though I will say that git has one big glaring problem with merge commits: they are effectively black boxes, and when you've have a big merge conflict, many git tools don't tell you how that was resolved in that merge. I recently came across a merge that wiped out some of my changes with no clear reason why. I redid that merge and there was no merge conflict at all, so it's still a mystery what happened there.

Still, rebasing has caused far more problems in my experience. It's only suitable for trivial, local cases and never on commits that have already been shared (pushed).

Not taking sides here but want to point out one thing:

When I took the Uber self driving cab in Pittsburgh (randomly called on my Uber), there were two people in the car.

One person was a driver, and the other person was in the passenger seat with a laptop. They were both very polite. The person with the laptop was very focused and watched the sensors take in information.

The driver -- at least in my case -- was very cautious and almost never let the car do anything by itself. He was almost driving it the whole time.

This is right after Uber brought over the team from Carnegie Mellon (so 2015 ish?).
