sertorius··on A global house-price slump is coming?
I think 30-year fixed mortgages are somewhat of an American phenomenon (perhaps due to the luxury of having the global reserve currency). They are not generally available in Canada or UK, where 5-year fixed rates are the norm.
sertorius··on Ask HN: Is there an “uncanny valley” effect with startup MVPs?
Not to pile on, but there's also a typo right on the first screen: "Lisitings". Also, inconsistent use of periods on bullet points.
sertorius··on Ask HN: Is anyone else glad the crypto market is crashing?
Coinbase has KYC ("Know your customer") policies explicitly to comply with anti-money laundering.

Edit: besides that, the point of 'laundering' money is basically to get it into a form where it is officially yours, in the light, with taxes paid. The NFT is a conceivably 'legitimate' transfer of value. I made a thing and sold it for money, and declared and paid tax on the capital gain - boom, legitimate.

sertorius··on Ask HN: Is anyone else glad the crypto market is crashing?
It was the perfecting money laundering vehicle. "I made a picture of an ape and 'some random anonymous person' bought it for $1M!"
sertorius··on Ask HN: What do you have for breakfast?
3 parts oat bran, 1 part psyllium husk - mix and put through a flour mill. Add some baking powder. Store this mixture and then at breakfast time add 1 egg and milk and fry as a pancake. I eat it with honey and butter. You'll probably want to make sure to have a glass of water with it, as the psyllium is soluable fiber.

Really tasty, and also an enjoyable experience 24 hours later.

sertorius··on Morons Funding the Fight Against Morons
Fair enough, but I doubt many individuals would be able to do much more than rein in the extremes - drilling in protected reserves, etc.

Buying shares doesn't necessarily mean you "support the company". You can be an activist and vote against current management. In many cases, activist investors have a big impact.

Realistically, it won't matter either way, but at least as an unhappy shareholder you have infinitesimally more power to influence the company than a grumbling outsider. Certainly more than the tiny amount of "support" that your stock purchase will cause should they issue more shares.

Private Doctor practices? How can they be vulnerable?
sertorius··on How to Get into Farming with No Money (1980)
Worth pointing out that at the time the article was written in 1980, it was the 100-year high in interest rates, possibly north of 20% in many countries.
sertorius··on After Your First Big Startup Success, What’s Next? (2014)
Are you sure you aren't thinking of "Noble House"? That's the one that takes place in the sixties. In it, Casey Tcholok tells her boss she's looking for "drop dead" money, which is once also referred to as "screw you" money.

Tai-pan is the original story of Dirk struan in the 1800's, and I didn't think the concept came up there at all.

sertorius··on Show HN: RedixDB – a fast persistent key-value store with the Redis protocol
Thanks for this!

Is there a suggested way to get a list of keys based on wildcard? I note that the infamous KEYS command is not listed as supported (and fair enough). Is there a suitable non-Redis backend command that can get this info?

sertorius··on Multithreading Rust and Wasm
> this browser does not have SharedArrayBuffer support enabled

It was disabled for Spectre safety reasons, but it can be re-enabled by navigating to "about:config", searching for "javascript.options.shared_memory" and toggling it to enabled. (But it was obviously disabled for good reason, so might want to enable it temporarily)

sertorius··on How the U.S. Saved the World from Financial Ruin
One would be the suspension of mark-to-market accounting procedures, where the requirement to value a bank's assets under current market conditions was suspended and they could value them under "ideal market conditions", which was fairly subjective.
sertorius··on Redis 5.0 RC1 is out
Just wanted to affirm this - I saw the streams announcement last year on the same day that I was having issues with Kafka and I implemented it into production for processing IoT time series data right away.

It was probably a bit too early for production use, but it worked perfectly!

One nice advantage of it vs. Kafka is that given that it's so lightweight, a Redis instance with streams can be dedicated to each customer with its own port and firewall setup and give you a really solid security story for clients who are paranoid about such things. (Kafka security is possible too of course...but harder to explain for a layman.)

Thanks antirez - it's great. I've written a python Redis iterator that I'm looking forward to PR'ing to the python client to encapsulate the XREAD timestamp tracking bit and manage timeouts.

sertorius··on Ask HN: Were we more productive 10, 15, or 20 years ago?
> Your task is to create a lasting representation of the struggle and beauty and plight of the human race. > Your task is to bring meaningful, sustainable, and relevant hope and quality of life improvement to society.

I'd be curious as to your opinion on the shape of this curve in history. Did we peak at some date in history? Perpetual downward slope? Perpetual upward slope?

sertorius··on REPL-Driven Development (2017)
The "Open Debug Prompt" in Pycharm is the best of both. Breakpoint at the point of interest, enter the REPL, and continue writing at the prompt. Also good in Matlab. I hope I can see this feature in Rust someday, although it seems like a tall order for a non-interpreted language.
sertorius··on Announcing Rust 1.23
> If you are interested in learning a C++ like language, I would recommend Rust. If you are a C++ programmer, I highly recommend learning Rust.

Also, if you are a Scala programmer, I highly recommend learning Rust. There are major similarities, and the ownership/borrowing concept is an improvement over Scala's JVM GC issues.

sertorius··on Fish: A user-friendly command line shell for macOS, Linux, etc
I use the following lines in my .bashrc to search the history based on a half-typed command (taken from https://stackoverflow.com/questions/1030182/how-do-i-change-...):

    if [[ $- == *i* ]]
    then
        bind '"\e[A": history-search-backward'
        bind '"\e[B": history-search-forward'
    fi
sertorius··on The compelling case for working less
I believe he was referring to the general living-in-the-present attitude rather than the supported-by-your-child part.
