Yea, my employer is on Google, it is impossible for me to transition out completely. Even though we would like to move out of Google, it is a herculean task since it is so deeply embedded into the organization. E.g., just having all your Google Docs with Google means there is no straightforward way to retain all the docs, along with all the links etc scattered around in emails, and be able to retain access permissions to the docs in any meaningful way. It is much easier to not get sucked in if you are starting a new company.
That's one concrete way to view determinants, but it's not _the_ way to think about them.

Determinants are kind of abstract and even inelegant. This is because it's defined in terms of coordinates rather than abstractly. A coordinate free definition exists, but it's very complicated.

Ideally they would not be taught at all, but it's useful for doing exam problems. Cramer's rule in particular is quite useful when solving simultaneous equations in engineering under exam conditions, for example. Even in computer/engineering applications, row reduction/diagonal normal form type are used instead.

Determinants are a way to get a scalar number out of a matrix. You have linear forms, bilinear forms, and multilinear forms, the latter of which determinants fall under.

There are certain properties you would like the determinant to satisfy, such as det(AB) = det(A) det(B), so that the determinant can give you an idea of whether a matrix is invertible. Eventually you work out that a determinant _has to be_ a multilinear form with certain properties (alternating, skew symmetric).

Again this is all very complex and messy. Initially 'linear algebra' was just the study of determinants, because people thought of math in terms of solving equations. Linear algebra, as it's known today, came later.

Bilinear forms turn up all the time, so ideally you would first learn bilinear forms, then learn the properties a bilinear form can have (e.g. alternating, skew symmetry, etc), and then learn determinants in that context.

Doing it once is harrowing. Even doing it the tenth or the hundredth time might be harrowing.

Doing it the thousandth time is starting to get old.
Doing it the ten thousandth time is business as usual.

The place to improve from is not as good as you may think, "On the Demo-2 mission, NASA has estimated a 1-in-276 chance of losing the crew at some point." Once you have full re-usability, you can fly rockets several orders of magnitude more times. When you're flying that often, you have the ability to work out the kinks.

If instead you limit to what today feels the safest, you might limit yourself from full re-usability and eventually being much safer.

If you want to still go for full re-usability, adding a backup system might actually make things more dangerous: It's another thing that has failure modes. Redundancy can be a double edged sword.

With my Windows/UWP and Android hat on, this only works when async is the only model available and the whole stack is designed for async programming, thus making it somehow easier do follow up on it.

This is actually the reason why those stacks don't offer sync APIs.
The fine (and others like it) is a meaningless gesture. Unless companies like twitter start getting fined in amounts that aren’t pocket change to them, there is literally no incentive to change their abusive behavior. They make enough from abusing their users and absconding with their data to pay these paltry fines a hundred times over in most cases.
Re: Not bombing Kyoto, apart from Stimson's personal reasons, I thought this was also an interesting one:

>Postwar political considerations did affect the choice of targets for the atomic bombs. Secretary of War Henry Stimson ordered that the historically and culturally significant city of Kyoto be stricken from the target list. (Stimson was personally familiar with Kyoto; he and his wife had spent part of their honeymoon there.) Truman agreed, according to Stimson, on the grounds that “the bitterness which would be caused by such a wanton act might make it impossible during the long postwar period to reconcile the Japanese to us in that area rather than to the Russians.”[0]

It's not as bad when you keep it as simple as possible. The first version of the 'generator' for my blog (shameless plug: rubenvannieuwpoort.nl) was written in one or two days. It's just a couple of bash scripts (and one Python script), really (see https://github.com/rubenvannieuwpoort/static-site-generator). Now I haven't wrote a lot since, but that has to do more with perfectionism and being busy).

This looks awesome! One prospective customer group, I'm helping a teacher friend of mine (she teaches Y1-4) as she produces basically an episode of Playschool/Sesame Street per day to her students.

She's working in iMovie and looking to move to Final Cut Pro, specifically for better editing and effects. So this looks like an awesome halfway house.

I can also see a marketplace for templates around your editing product that would be another great sideline for creators.

Questions though about storage and video streaming. Are you offering the streaming service along with the editing?

Or is this purely the editing stage and then there's a take the raw footage and upload to somewhere like mux.com for the encoding and streaming requirements?

Ask HN: What important problem are you working on solving?
Unfortunately, most engineers aren't in a position to choose to work on a particular problem with high impact on our future. Those of you who do, what did you decide to work on and why? Was it the problem itself or the company that got you interested?
The poster is describing the future imagined by Arthur C. Clarke and Stanley Kubrick in 1968, not reality.

We ended up with a lot fewer nukes, and a lot less space. (Also fewer trippy alien wormholes.)
Yeah, though my outlook on oil is longer-term than current market trends. Don't worry I loaded up on tech stocks too
I agree. For a space craft that did it's 150m "hop" in 1992 it was even more impressive (especially considering how much the computers and IMU weighed in that thing!)

I'm not convinced though that it ever really to achieve it's SSTO goals and still land it. With on orbit refueling perhaps (as could Starship in a similar scenario). It was also shooting for much lower mass to LEO.

The HN effect?
Good - 2FA is the responsibility of the user and resetting it kind of invalidates the security it helps bring.

I think the bigger issue is that people's 2fa codes are still tied to their phone. You can lose your phone at any moment, which is why i've always disliked apps like Google Authenticator which don't let you export 2fa keys (for good reason).

I personally use 1password, but there's definitely room for a cloud storage solution that safely holds 2fa credentials
It's a good point; once you start thinking about it you realize that the locks are only a (small) part of overall security. For example, can someone break a nearby window pane and unlock the door? Can they bust open the door with a strong kick? Are the windows on the second floor (for a house) always locked? A good book on this topic, about how differently thieves think about space and common security features, is "A Burglar's Guide to the City".

I started to write that exact script myself (go to the point of realising jq probably wasn't going to cut it :), motivated by the desire to help others escape too but I just ran out of steam.

Plus, there was something not right about the fact I was actually paying for these damn tools and still having to write my own code! Thought I'd just get out as quickly as I could and not go back.

But having seen others in these threads complain, I do now feel kind of bad!

If the US can trust the UK with information on nuclear weapon designs and delivery systems, surely it can handle a few UK citizens working for SpaceX?

In the unlikely event that the UK and US had some falling out, the US government could always order SpaceX to lay off UK citizen employees.
I just used the "1PIF" export from 1p, which bitwarden supports for import (but the 1p cli doesn't support).

Top work mate, looks great.

I had a question about your work ethic on this project. Did you treat like a full time job Mon-Fri 9-5 or more like College project with frequent all-nighters? How did you sustain the motivation to keep going even through the rough patches as a solo developer?

Would love to read blog post about your journey through this.
I'm not sure where you're getting this price, is that your calculation with GST/HST?

Plans on https://1Password.ca are CA $7.95/month (CA ~$96 for the year) for monthly billing. We think this is a killer price for five family members without any restrictions like living at the same residence. You do save quite a bit with annual billing, but I understand that's not for everyone.
Isn't there Authy?
You can export to multiple devices now on Google authenticator, other 2FA apps have also supported that for quite a while.

As far as cloud storage goes, standard notes might be a good option, I don't use it for 2FA, but it's an extension they provide.
Microservices for instance; companies spend a lot of money to manage microservices to end up with a really bad implementation of Erlang OTP. Bad enough to mostly see they now also created a very bad version of the monolith they should have started with and thus go back to a monolith. Or macroservices as Uber now calls them.

Nosql usually ends up as a really bad version of a rdbms with a query language that is a very botched version of sql. And then we move to postgres as it is actually better in every way.

Javascript was literally (the author wanted to implement scheme but that did not look like Java) a really badly done version of Scheme which had to look like Java. So this is directly Greenspuns 10th rule.

And we can go on: all these things have solid and scientifically sound implementations and yet we reinvent the wheel, badly and then usually drop it or try to reverse the damage by actually thinking about history for a second (wasm).
We managed it by nobody bothering to write apps for Linux.
So, we supposedly need twice the annual global production of cobalt to replace all of the UK fleet, but nobody seriously expects this to happen within a year. Average age of cars in Europe is somewhere between 7 and 9 years and it takes 10-15 years at least to replace the whole vehicle fleet unless you want the government to give away cars for free.

Phony, sensationalisy calculations like you'd expect from a tabloid.

I'm glad that the trend of reforestation is happening in Europe and will contribute to co2 capture. I think it's less due to deliberate efforts and more a product of food production efficiency, closing of small farms and people transitioning to urban env.
Besides being noticeable on satellite images it also affects local climate so in my area (NW Croatia) due to reforestation they had to update the climate models due to forests holding more moisture. (another side effect is increased number of wild boar)

PSScriptAnalyzer 1.19.1
Static things should be generated server-side (even if those static things are dynamically-gwnerated), and things that change on the page after load, interactively or by timers, should be rendered browser (client) side.

Client side rendering has become popular because it reduces server load... but unfortunately increases processing time in the browser, which can slow things down for users.

There's solutions (like Gatsby, which is its own layer of complexity) and cheats and workarounds, but the standard should be that if a page will contain the same information for a certain state on an initial load for that page, that content should be generated server-side. Anything that can't be or is dependant on browser spec or user interaction should be client-side.

I just don't believe in making the user process a bunch of repetitive static stuff that can be cached on the browser from the server or compressed before sending. There's gotta be more consideration of user experience over server minimization.
Every bit of interactivity/ reactivity that product wants to add to the page feels like a weird hack that doesn't quite belong there, polluting the simple, declarative model that your views started off as.

This doesn’t need to be the case though. There have always been server-side frameworks which generate the client-side parts for you automatically, so you can mostly avoid writing any javascript even for the interactive parts. Check out rails/turbolinks/stimulusjs (used to build basecamp and hey.com) or the TALL stack (increasingly popular in the php community) for modern day examples.

New rocket, new engines, new targets.

If Falcon 9 (the current rocket) was a motorboat capable of going from one port to a neighboring one on the same sea coast, this is the early prototype for a transatlantic liner.

It's designed to be much bigger, much faster and more powerful, while being fully reusable (like a plane) and extremely cost-effective, potentially 10 times cheaper than the Falcon 9, which is already the cheapest launch vehicle. That opens up all sorts of new possibilities.

And these hops are the first concrete steps toward that.
There's a profile of the dude in Wired that goes over what made him so valuable in Larry Page's eyes. https://www.wired.com/story/god-is-a-bot-and-anthony-levando...

Basically, he was one of the key founders of the project that made Google Maps what it is today (a crown jewel of Google with one of the best cartography datasets), vs what it was originally (better UI to third-party, licensed cartography data).

I remember about 12 years ago somebody from the GIS industry, scoffing at the notion that Google might even try to go do some mapping of their own. For him, maps was something Navteq and TeleAtlas knew how to do, and a search engine was deeply misguided if it thought it could venture into that space. That was honestly the prevailing wisdom at the time — it was going to be hard for web-based Google to even deal with the ugly real-world-ness of mapping.

Fast forward to today. Google Maps basically showed the GIS crowd how their work oughta have been done all this time. They invented street cars, street view, and actually made it work; and they used the data to produce accurate maps of the world.

So to your question, what led this guy to an astounding level of monetary reward was that he was part of a team that made a big, calculated bet with Maps and executed very, very well on it. That gave Page ample reason to compensate them well, and it gave him trust that they could handle more projects where they would show up incumbents (such as the traditional car manufacturers, whose inroads into self-driving tech had been very timid for decades).

And it's not clear that they are close to self driving cars, but they certainly contributed to upping the game of that whole industry.

So there's your recipe :) I'd bet that folks who came up with the key tech behind the iPhone are in similar positions at Apple, given how they turned the whole mobile phone business on its head (remember Nokia?).

EDIT: I don't mean the above to indicate that the reward was deserved in any way. Likely, a lot of what happened here is luck plus outstanding team work rather than individual lead performance. But to the question being asked, this is the kind of circumstance and outcome that seems to have supported, in one man's view at least (Page), that level of compensation. If you look at folks at Google who made/make big $, the story is often similar - they led products that were fledgling challengers into industry leaders within a few years (Chrome, Android...).

One of the major difference when you think of any concrete items like flower, gardens is that they are private goods. Public goods especially information, laws of physics, idea, mathematics etc. are hard to create but no costs to consume. Hence, the walled garden is not about keeping most people out of view i.e. Wall Street J etc. but keeping the noise from the creation so there is a point for the OP to post his question in a panic. Public goods like F=ma is very hard to be created and what motivation to create one is a big question. This is especially if it is networked public goods. And some public goods are useful to one or one group but not the others. That is the fundamental problem here.

Guess the one above this poster has right that the analogy is not totally right. Still if one assume the flower can be viewed a trillion time but the question is creation, walled garden is a good metaphor.
> Yes it is.

I don't play along with excuses. As I said, if it was really about that, they had numerous opportunities in the past four years.
