Wow I never heard of this, a real life Jules Verne story!
Definitely true for any mid to large size city anywhere in the west of the US as well. Not quite $1.5M bad, but even if you’re making a hefty $100k as a young person in tech (way above normal salaries for these areas), saving towards a $500k starter house is a very hard ask on top of paying off student debt and rent. If you don’t have existing equity or an abnormally large salary, you’re screwed.
Databricks didn't run the Snowflake comparison in-house. From their article it says: "These results were corroborated by research from Barcelona Supercomputing Center, which frequently runs TPC-DS on popular data warehouses. Their latest research benchmarked Databricks and Snowflake, and found that Databricks was 2.7x faster and 12x better in terms of price performance."
Its quite simple. With the advent of globalisation the self-interest of the elites is no longer in alignment with the national interest.

They can make money far more easily by employing Chinese workers, growing Chinese industry, than they do local.

And of course, anyone that pushes back against this is (conveniently) a "xenophobic, racist, white supremacist, Trump-voting blah blah blah...".
No-one is coming for anyone.

Let me show you how far you've drawn your bow, by reductio ad absurdum.

> First they came for the drink drivers, and I did not speak out— Because I was not a drink driver.

> Then they came for the heroin dealers, and I did not speak out— Because I was not a heroin dealer.

>Then they came for the construction companies that built buildings that collapsed and killed hundreds, and I did not speak out - because I didn't run a construction company that knowingly adulterated concrete to increase profits.

These are all equivalent "mandates" to secure the public good.

But hey, when the secret police start dragging unvaccinated people away to death camps, I'll freely admit you were right. Make sure to let me know when that happens.
That's cool, but why not just carry extra batteries and switch?

For about the last 35 years (since Bush 41) I saw no discernible difference between the parties in terms of governance (lots of difference in rhetoric though). However, once the pandemic hit there tended to be a much greater amount of authoritarianism regarding pandemic policies coming from elected democrats. Interestingly it was across the board as well. Even down to the local community levels, it seemed to me that the democrats were interested in way more heavy handed approaches.

This seems to have now expanded beyond pandemic management to other things as well. That is a concern for me.
That is not correct.

When complex numbers are represented in the matrix form mentioned by the other poster above, the multiplication of the complex numbers corresponds to the multiplication of the matrices, not to multiplications of vectors by matrices.

The matrices of this form, having just 2 parameters instead of the 4 parameters of a 2x2 matrix, are obviously just a subset of the general 2x2 matrices.

However this subset is closed to matrix addition and multiplication, so it is a field isomorphic to the complex numbers.

This representation of the complex numbers is useful to understand that the multiplication rule for complex numbers is not some random arbitrary rule, but it is the same as the rule for matrix multiplication, which is also not a made-up rule, but it results from function composition, when you compose the functions of a vector expressed by the multiplication of a matrix with the vector.

Actually the construction of the complex numbers goes like this, if you consider the transformations of the 2-dimensional vectors that correspond to a scaling and a rotation of the vector (which are a subset of the linear transformations expressed by multiplication with a non-singular 2x2 matrix of general form), and you compute the matrices that perform such transformations, you arrive at 2x2 matrices with 2 parameters of the form shown by the poster above.

This set of transformations happens to have the algebraic structure of a commutative field. Because the matrices are defined by only 2 parameters, you can simplify the operations by keeping just the 2 parameters and using rules for operations expressed directly with them.

Thus you obtain the standard rules for operations with complex numbers.
Moreover, with no pressure, many kids will simply not put in effort to learn. That something so common sense is now neglected is bizarre.

Fantasy sports is explicitly betting, where any winnings are acknowledged to come from the losses of other players. On average, players will lose because of the house rake, but skillful players may beat the odds.

Axie Infinity seems to be something else, where everyone can "win" just by playing the game. For example, daily quests provide SLP coin which is minted from thin air; there's no skill or risk involved here. The only way this can be sustained is with a flux of new players.
Performance is only one part of the story. The major advantage Snowflake (and to some extent Presto/Trino) brings to the table is it's pretty much plug and play. Spark OTOH usually requires a lot of tweaking to work reliably for your workloads.

And always use "-fwrapv -fno-strict-aliasing -fno-delete-null-pointer-checks". Those are source of the hardest to reason about UB and the small performance benefit is not worth the risk. I would love to always be certain I haven't accidentally hit UB, but that's equal to the halting problem, so for peace of mind, I just ask the compiler for a slightly safer variant of the language.

P.S. and old code definitely needs them, as at the time compilers didn't optimize so aggressively and lots of code does weird stuff with memory, shifts, etc.

I'm a little bit surprised how seriously databricks is taking this, but maybe it's because one of the cofounders laid this claim. Ultimately what you find is one company is not very good at setting up the other company's system, and the result is the benchmarks are less than ideal.

So why not have a showdown? Both founders, streamed live, running their benchmarks on the data. NETFLIX SPECIAL!
You can set up email alerts on every transaction for credits cards in many banks. Probably not all.

Totally agree, the Canadian banking system is a corrupt cartel the levies it’s own tax on every Canadian. This was made even more clear to me when I moved to the Netherlands and every banking fee was suddenly 1/3 as much as in Canada for the exact same service.
Goodhart's law: Any observed statistical regularity will tend to collapse once pressure is placed upon it for control purposes.
Very good perspective. It’s the “epicurean treadmill” of technology. 20 years ago, you would’ve spent days or weeks getting a server and infrastructure set up. The slower pace was due to natural constraints and generally speaking things are simpler within constraints. Now that you can spin up an infinitely scalable, globally available cluster of servers in minutes, the question rather becomes “what now?” It’s absolutely an objective improvement. Things have gotten better. But the human mind is not built to be satisfied. We always reach out for more, to push the boundaries, and now that the boundaries are pushed so much further than before, the questions and demands asked are much greater.
Can someone ELI5 what Snowflake and Databricks are? I spent a few minutes on the Databricks website once and couldn't really penetrate the marketing jargon.

There are also some technical terms I don't know at all, and when I've searched for them, the top results are all more Azure stuff. Like wtf is a datalake?
Why are you being downvoted? It's a nice joke :)
There's an official TPC process to audit and review the benchmark process. This debate can be easiest settled by everybody participating in the official benchmark, like we (Databricks) did.

The official review process is significantly more complicated than just offering a static dataset that's been highly optimized for answering the exact set of queries. It includes data loading, data maintenance (insert and delete data), sequential query test, and concurrent query test.

You can see the description of the official process in this 141 page document: http://tpc.org/tpc_documents_current_versions/pdf/tpc-ds_v3....

Consider the following analogy: Professional athletes compete in the Olympics, and there are official judges and a lot of stringent rules and checks to ensure fairness. That's the real arena. That's what we (Databricks) have done with the official TPC-DS world record. For example, in data warehouse systems, data loading, ordering and updates can affect performance substantially, so it’s most useful to compare both systems on the official benchmark.

But what’s really interesting to me is that even the Snowflake self-reported numbers ($267) are still more expensive than the Databricks’ numbers ($143 on spot, and $242 on demand). This is despite Databricks cost being calculated on our enterprise tier, while Snowflake used their cheapest tier without any enterprise features (e.g. disaster recovery).

> Our civilization will make the transition. It will be messy and could have been much less painful but we will do it.

I wish to see this kind of positivity around me more often. I have worked with a colleague or two in the past who viewed problems as something that needed to be solved, and were a step or two ahead of the rest of us in terms of finding solutions. Lately, I see that the default reaction to problems is to complain. Don't get me wrong... complaining is fine if it leads to action, but isn't it rare.
I have six children from 5 to 17 in my blended household, I know how much lockdowns suck.

But lockdowns prevented our healthcare systems being overwhelmed thus causing many more excess deaths, and protected vulnerable people like my wife who has heart failure, where a Covid infection is highly likely to lead to death.

So, I genuinely thank you for abiding by the lockdowns, I know how difficult they were, but your doing so saved the lives of many people like my wife, so I really do appreciate it, and acknowledge that it was hard.

Exactly. Not sure about Netflix special, but there are experts that have dedicated their professional careers to creating fair benchmarks. Snowflake should just participate in the official TPC benchmark.

N26, a German bank, has unlimited free ATM withdrawals in most countries and only 3/mo in Germany.

Yeah, that’s why eventually paid 5 bucks a month more for an account without an overdraft facility, meaning any negative transactions would be rejected. I can’t believe this isn’t the default.
Honestly this sounds absolutely horrible to me…

Very much true. I saw a joke tweet recently something along the lines of - It's amazing how many data engineering scaling issues these days are being solved by just paying Snowflake more money.

Spark does take a lot of tuning, but then I'm guessing Databricks offer that service as part of your licensing fee? (I'd hope so if they're selling a product based on FOSS code, there has to be a value add to justify it)

There are alternatives that don’t involve DRM or Bosch at all.

I built our ebikes around regular bikes using a TSDZ2 torque sensing motor and an em3ev 52V battery. Total cost around 600$ + bike + tools. The battery is already assembled so no risk of setting your house on fire. The torque sensing makes it really natural (like having bionic legs), the whole thing has an open source firmware if you want to replace the Chinese made one (https://github.com/OpenSourceEBike/Color_LCD) and you can use any battery with it. With a 850Wh battery we get around 100km range.

There is also the cyber bike for which you can buy plans and build from scratch but that one is more of a motorcycle and you’ll probably need certification + insurance to use it legally.
As the one who told the joke, I disqualify myself here.

But at the risk of being the downvote explainer, perhaps it is because some jokes are best left unexplained?
True, but not every approach to an airport is a nice constant vector.

Continuous descent operations are the optimal, but there's plenty of suboptimal airport approaches that require level flight at a height where fuel efficiency is far less than at cruising altitude.
> hey, if they're happy, who gives a shit?

They should, and the reason why is recycling.

Everyone believed the claims that recycling would help the planet. But it turned out that most (not all, but most) recycling was being burned or buried, because it was never going to be cost effective. Nobody verified the claims, but it "made them happy" to think they were helping the planet. And now we live in a world with just as much trash and even more microplastics, when we could have been making real changes to actually reduce our waste impact. Letting people blithely say "oh I'm doing it to help the climate" helps people be happy while exacerbating the problem they're pretending to be helping to fix.

Another example is people who say "hey I'm not racist! my best friend is black!" while their subconscious bias at work actively prevents black people from being hired or promoted. Or "I'm not sexist! I love women!" while speaking over them in every meeting and shooting down their ideas. It's not enough to just feel good about what we're doing. We need to verify we're actually helping, not just assume we are.
You're grey'd out, but based on some quick research this appears correct.

> PostgreSQL is implemented using a simple "process per user" client/server model. In this model there is one client process connected to exactly one server process. As we do not know ahead of time how many connections will be made, we have to use a master process that spawns a new server process every time a connection is requested. This master process is called postgres and listens at a specified TCP/IP port for incoming connections. Whenever a request for a connection is detected the postgres process spawns a new server process. The server tasks communicate with each other using semaphores and shared memory to ensure data integrity throughout concurrent data access.

This post is entirely nonsensical, and I'm confused how something like this ended up on StackOverflow's blog.

Language syntax has nothing to do with framework features, and especially things like writing UI components, managing state, and updating the DOM. The fact that the major frameworks have continued to explode in usage, and that we've seen new frameworks like Svelte and Solid come out, clearly says that the answer is "no".

Plus, why in the world is the post talking about "with the release of ES6", when that came out 6 years ago? I wondered if this was somehow a repost of something that had been written back in 2015, but a search on a couple phrases didn't turn up any other hits and the post does link to some other SO blog posts from 2017-18.

If I didn't know better I'd swear this was an April Fool's joke or a parody.

Not really what the article terms for head of growth... But here's my experience.

Fortune 50 company, we promoted GM to "chief growth officer".

In reality it was just the c suite shuffling their deck of leadership roles with a new spin...

The amount of dotted lines in the new structure practically didn't work.

Role didn't last long, 6 months into only like 10% of annual goals, it was eliminated (and the chief growth officer shuffled into another executive position).
