1) It's hard to hide things in a physical store. There are some tricks but if you want Brand A cereals and the store has them, you can find them in the cereal section. Amazon has in my experience, sometimes hidden product brands entirely or beyond page 4-5, favoring their own or prime products.

2) When a supermarket takes on Brand A cereal, the Brand A owner makes little risk, they get paid whether they sell or not. The supermarket is taking all the risk. If they bring their own store brand, they still run the entire risk, now for both stocks. If cereals stop selling well (because there is a milk shortage) then the supermarket is loosing a lot of money. Amazon faces no risk, they can have the vendor for Brand A continue to sell non-prime cereal from their own stock so amazon faces 0 costs if it flops. If the vendor does well they can be onboarded for inventory management and prime shipping, amazon takes more risks and more profit. Lastly, they can use methods like "We suspect the product is counterfeit, send bills for when you bought it" to gain direct access to the manufacturer of Brand A. Now they can sell Brand Amazon directly from the manufacturer, leaving the Brand owner of Brand A in the dust by selling the same product, that did well, cheaper and hiding them in the search results below their own.

The supermarket equivalent would be that the supermarket subsidizes the Brand A seller from their value-add in-store things like customer payback cards after a while, then blackmails them into giving them the manufacturer by threatening to not sell their popular product, then selling the manufacturer's product under an in-store brand and the Brand A cereal is only available under-the-counter. Brand A seller is also entirely co-dependent on the supermarket as that supermarket is 90% of the market.

I know you have wallmart in the US but in the EU we do have some variety in supermarket chains (ALDI Süd/Nord, LIDL, Edeka, Rewe, etc.).
Thanks, yeah. Looks like it would work. If you're light-skinned. Otherwise, it looks like a big burn hazard.

Wow.
Even SSD's have appreciable latency. That means you typically read far more code into RAM than you need to run.

Having said that, the executable size in RAM is tiny compared to the runtime ram usage.

The thing I love about magit is that it teaches you how git works instead of trying to hide it from you.
I take your point, and agree, but it's become deeply untenable to share a NYTimes article to prove any contested political point. That place has well and truly set fire to its reputation as an impartial reporter.
Added to that China has built the world a really nice base near the Spratlys that I'm sure could be quite quickly overwhelmed by another country and used as a nice forward base to control the SCS.

Very nice of them to build that.
I think teaching sets like this totally misses the point. Finite sets are trivial (and pretty useless), so there is no use for schoolkids, it is just a waste of time.
I really doubt that... In my environment (from helping people with their computers) I regularly hear things like "Damn HP, wanting €80 for a set of tiny ink cartridges".

And most people know very well how to find their aftermarket ink, either in the shop or online. None of them think what they're buying is official. Sometimes (but rarely) really cheap ink does cause printer problems, but even then it's worth the risk. An Inkjet is pretty much "total loss" after the first ink change anyway (a full cartridge set costs close to what the printer is worth).

I always advise Epson EcoTank ones for inkjet use (though these are pretty pricey) and Brother for laser (which besides not being bound to expensive toners are actually some of the cheapest printers around too). For most people a simple B/W laser is sufficient anyway (and just to order photos online).

But they often end up falling for Canon, Lexmark or HP again because they're just cheap and fall for their marketing even though they were bitten by extremely overpriced cartridges before... <facepalm>
It's not just fraudulent activities but things like "can the state keep accepting mail-in ballots for 9 days after the polls close"?
You can do that! I've done it. I tapped into Uniscribe on Windows, Core Text on macOS, and PangoCairo on Linux. The problem is that this looks horrifically inconsistent between platforms. You also end up doing a ton of work to figure out how to accomplish a simple task like, "I want this text in this box, that word is italic, please add the line breaks, here is a font file." That's simple on one platform, but you end up having to duplicate everything you do across all the platforms you support, and typically you will find one platform that breaks your assumptions about how libraries should handle this task. Your code ends up being convoluted so it can hide the (major) differences between different APIs.

It's actually so much work that you probably want your game engine to do it internally in a way that is consistent cross-platform. Fortunately, most of the guts have already been figured out for you by the amazing people that work on HarfBuzz. The basic formula is to take your Unicode string, take your font, and feed it to HarfBuzz to have HarfBuzz figure out the metrics and glyph offsets. You then use the metrics to do layout and line breaks.

It is a lot of work, but it turns out to be less work than figuring out how to this working cross-platform using system libraries. This is also, generally speaking, how web browsers deal with their text. There are a couple other pieces that you need like text segmentation but these are tractable.

Ask HN: When to Use a Dev Shop?
At a startup, sometimes the core team lacks bandwidth for certain projects. In these cases, hiring an outside dev shop seems like an interesting option. Of course, there are some trade-offs, in terms of maintenance, knowledge transfer, quality, risk, timelines, etc.

For all those seasoned devs/eng leaders out there, what are your heuristics for when it is a right, or wrong, call?
Thanks.

This data is from the USA, it would be interesting to compare to countries with free healthcare.
Thank you for doing this kind of work. That commit is funny -- I've read that there's similar stuff in graphics card drivers too :)
For a few years before I sold my small (UK) company, our employment contracts had a bonus clause in. It guaranteed a bonus payout from a pool of 5% of any future sale, based on a multiple of years service (up to 5) and salary at the time of sale.

We sold for a similar sum and the bonuses were pretty small by SV standards - a bit more than £20,000 for a few, down to a few £00 for people who had just joined (maybe 50% annual salary for a few).

Me & my partner had a fishy earnout clause over 12 months, but I got us pleasantly fired after 3. Half the staff got made redundant after 6, which I don't believe was a surprise to any of them. Nobody buys a business for its cosy culture, or sells one expecting it to stay.

I think it's right for founders to be up-front about the likelihood and consequences of an exit, which is why we put it in our employment contract. But IMO more than 10% would be very generous for these ordinary private buyouts at 4-5× profit - no rocket ship valuations. At least that's clearer and more certain (and less tax efficient) than the kinds of games people play with options & rounds of funding.

UK tech companies, salaries & employee expectations are a whole different world from what's discussed here. Maybe Baremetrics was closer to that world than SV.

All network traffic in the US should be seen as the opposite of innocent untill proven guilty: Unless you can prove otherwise, everything we know of surveillance tells us that of course everything and everyone was spied upon. I can't think of any reason the NSA and/or CIA should not have spied when they do so on everything else they can get their hands on.
I agree. I am writing my project a certain way to achieve a goal I call reimplementability.

This means that I try to design in such a way that a reasonably competent dev could sit down and rewrite the whole system in a couple hours/days/weeks.
The point of VueScan is that it acts as its own driver; it accesses the scanner directly via USB without relying on an OS-level driver so it should work (they have a free trial version to test with).
The app is free. How do you plan to make money from it, so that it can stay in operation? Don't want to suddenly find out all our passwords are gone.

Why would we put photos inside the app rather than use a shared photo library?

> And it sounds like the early employees get nothing, other than not getting fired immediately.

Why early employees should get anything from an acquisition ? If they don't have stocks, they shouldn't, that's how it works, a company belongs to its shareholders, not its employees.
> I've never heard that definition of "tragedy of the commons."

Is a simplification, but the idea that I wanted to stress is that everybody in a "tragedy of the commons" case has some kind of legal rights to exploit the shared resource.

Pirate fishing doesn't has rights over the resource. Is an illegal activity, parallel to the legal quotes, that boycotts any measures taken for a sustainable management.

>Wouldn't E2E encryption of a call with 40 participants require each user to have 39 times the upload bandwidth, in order to send 39 video streams encrypted with different keys?

I think you use public key cryptography to securely distribute an encryption key for that call. So the host sends 39 messages encrypted with different keys containing a shared key. Then everyone uses the shared key to encrypt/decrypt the call data.
Any advice on how to get there? I'm a contractor after having worked full time for a few years. Working with a very few long term clients, just me.

I use stashes via the autostash feature. For unspeakable reasons, I have to have locally modified files in my repo to run the software and the tests. (Of course, it shouldn't be like this.)

So I can `git pull --rebase --autostash` and this works even with local modifications.
I don't get to change my mind later and get mad that you didn't give me more and call you immoral.

But on the other hand, if you’d agreed to sell me your car at a price under what you might be able to get elsewhere—maybe because I was financially struggling and you were doing me a friendly favour—you’d probably be pretty miffed if I won the lottery and still demanded you stick to your offer…

> For example, not only students but also modern algebro-geometers on the whole do not know about the Jacobi fact mentioned here: an elliptic integral of first kind expresses the time of motion along an elliptic phase curve in the corresponding Hamiltonian system.

This one resonated with me. At one point I had a problem that had to do with Kahler manifolds, but I knew nothing about them and only had some worked examples using basic ideas from Hamiltonian mechanics that I learned from Arnol'd's book. In hopes of resolving my issues, I spoke to some symplectic geometers and used Hamilton-Jacobi language. They vaguely knew what I was talking about but couldn't carry out any calculations.

I once heard an anecdote about Arnol'd that he came to France and lambasted the French mathematicians on a similar basis -- for all their writing, they couldn't carry out "simple" calculations with a clear vision (as once can when one has a physics motivation). It might have been the anecdote was referring to the Serre-Arnold debate -- thanks for that link.

Of course, Arnol'd has... high standards, to put it mildly. In his book, "Problems for children from 5 to 15", he writes in the preface,

"My long experience has shown that, very frequently, dimwits falling at
school behind solve them better than A-grade pupils, since – for their survival
at the back of the classroom – they must permanently think more than required
“for governing the whole Seville and Granada”, as Figaro used to say about
himself, while A-graders cannot catch “what should be multiplied by what”
in these problems. I have also noticed that five year old kids solve similar
problems better than pupils spoiled by coaching, which in their turn cope with
the questions better than university students used to swotting who anyway
beat their professors (the worst in solving these simple problems are Nobel
and Fields prize winners)."

One of the problems is to sum 1/n^2 from 1 to infty (this is for children not older than 15, remember). Not only would I be unable to do this without modern technology (like Fourier analysis), I also find it amazing that Arnold writes:
"prove that the sum is pi^2/6, that is, approximately 3/2",
as though the approximation were harder (or perhaps more important) than finding the exact value. To me, that small comment really underlines just how hands-on he was.

Edit: I remembered a joke.

Not only my basic needs, I also had a strong urge to reproduce - but that would be irresponsible without being able to support the offspring.

When I was younger I always had an insane drive for making money, which translated into tons of business ideas and a true passion for working.

After having kids and after having enough money to buy a house in cash, a lot of that business drive disappeared. I definitely feel like I completed a part of my life.
There is still some drive - and it's focused at creating enough value to pay all my expenses: food, entertainment, private school for the kids.

After that is done, I will spend my days working out, growing my kids, cooking, gardening, travelling.

I know society sells the lie you should be working yourself off (possibly for some giant evil corporation), hoarding as much money as possible until you die - but I couldn't care less.

Removing economic incentives would see a steady decline of value creation in society. Stakhanovism was most likely Stalin propaganda.

If a company signed a contract with Zoom in which e2e encryption was stated.

It sounds like OP is referring to a breach of contract. Even if they can't prove damages, they could still be entitled to some other remedy, like a partial refund. It would depend on the language of the contract, of course.

We use Notes for that on iOS. The advantage is that it then syncs to all of your other devices, be it your iPad, work Mac or your phone. Not sure if it syncs to Apple Watch yet. Does this app have any significant advantages over that approach? I like the design.

>>>General Catalyst’s (who had the lion’s share of that $800k) response showed just how classy they are: “We recognize the work that’s gone into the past 7 years and it sounds like this is a great landing spot for the team. We’re grateful for the opportunity to have supported you along the way.”
I think I might have managed to prevent mine from updating so far. Does anyone have an easy to follow guide to blocking it from internet access?
From my perspective (I've taken cursory dives into micro in the past), micro is analogous to the libraries developed by every company's infra team to decorate teams' APIs (opentracing, metrics, logging, etc), making them consistently useful with minimal impact on developer velocity.

If this analogy is accurate, it means can deploy these however you want. They're kind of like force multipliers on the effectiveness of distributed computing tools (RPCs, logging, etc).

I welcome refinements/corrections of this analogy!
There is nothing inherently special about Taiwan for chip manufacturing. Theoretically, Europe and the US can (and do, to some extent) challenge TSMC and China aspires to do so too.

The fundamental problem is that it is extraordinarily expensive to build a state of the art chip fab and it is extraordinarily difficult to make start of the art chips (process technology in the 7nm node range). The technology is heavily patented and, what isn't patented, is tightly controlled as trade secrets by fabs.

TSMC[1] started as a contract fab house with competent, but not state of the art, fab capabilities. Over time and with immense investments, they have become a leading (arguably the leading) fab. Intel is on par (arguably) or has fallen slightly behind TSMC in terms of state of the art fab capabilities. Global Foundries[2] (made up of former IBM foundries[3], Motorola foundries, and others, acquired by AMD and subsequently spun out) has fallen behind in terms of state of the art (e.g. 7nm nodes). Europe also has quite a few competent, but not state of the art, foundaries.

There are a ton of fabs that were state of the art but have not been upgraded - they are quietly fabbing billions of chips that don't need smaller geometry fab nodes and cannot justify the expense of moving to more state of the art fabs. "Moving" to a new fab node technology requires a significant redesign of the chip and would require requalifying, both of which are very expensive.

Tailscale raises $12M for its WireGuard-based corporate VPN
The nature of Linux platform problems is that they crop up for specific combinations of hardware and software. The biggest thing that Microsoft has over the open source community is the money to pay developers to bulldoze the combinatoric jungle that is compatibility. That, and the platform clout to get vendors to make their stuff work.
Certainly with government access to messages. The minds in charge would never let such an opportunity slip. They are set in the cold war of terror and that won't change for the current generation. So it is still not a good idea to use Zoom.
I don't disagree however the paycheck for engineering employees is often a lot less than one could get from established companies. Every startup I've talked to sold equity as a large part of the total compensation and argued it makes up for the cash difference.

So you're being asked to give up $100-200k/year worth of salary by joining a startup which isn't trivial. For a tiny fraction of equity with multiple restrictions (10 year expiration, 90 day window to exercise on leaving, can't sell it, etc.).
It may well just be me, but what I find valuable about syntax highlighting isn't the colours per se, but the differentiation between different kinds of token in the language (comments, keywords, argsb etc.) Therefore I don't really notice the individual colours, I notice when the colour changes.

The Qubes Master Signing Key is kept on air-gapped machine accessible only to the developers. It signs their keys and the fact that they are signed by it is already the evidence of its validity.

> Any data you save in the app is protected by military grade encryption (AES256 + PBKDF2). SecureAppy uses your passcode that only you know to encrypt and secure your data. This way, no one, not even SecureAppy can unlock or see your data.

Sorry, but 4-digit (seems to be the default) / 6-digit passcodes are trivially brute forced (for any usable PBKDF2 iterations), so that statement does not inspire a lot of confidence.

Also, I would recommend an actual security white paper detailing the design. Saying “we use AES256+PBKDF2 and end-to-end encryption” probably isn’t enough.

Another thing: passwords being default visible at rest (when you click to open an entry) may not be the best idea.
