grej··on I deeply regret my participation in the board's actions
No lawyers were consulted before sending that tweet clearly. Such a sad situation all around.
grej··on Unauthorized "David Attenborough" AI clone narrates developer's life, goes viral
When I call my bank, they use a "voiceprint identification" that requires me to say a sentence and then matches that to my voiceprint.

I am wondering if that is a massive security hole.

grej··on U.S. Economy Grew at 4.9% Rate This Summer, Powered by Fast-Spending Americans
Probably all Americans to some degree, and sure they're spending more but with rampant inflation, they're definitely not buying more.

Awesome thx!
grej··on Show HN: Classic Video Poker
This is amazing work, well done! I haven't seen such a great CRT effect but I would love to see that kind of effect available as something you could overlay on old retro arcade games.

Still no TouchID. Boooo!
grej··on How South Korea’s birth rate dropped below Japan’s
South Korea was among the poorest countries in the world - poorer than many countries in Sub-Saharan Africa as recently as the 1960s. Withing a single lifetime they transformed themselves into one of the most advanced developed economies on the planet with a madman (mad men) on their doorstep.

It’s natural that that kind of change will have some massive societal implications, many of which they are still sorting out.

Their birth rate is something that will require immense attention and work to begin to correct, but it’s worth noting what they’ve accomplished in getting to a place where they can afford to worry about that as one of their primary concerns.

grej··on The ocean has a fever
"Quadruple the cost of fossil fuel via taxes" - It's not what people want to hear, but this type of taxation will have no practical impact on the fossil fuel use of the world. Any fossil fuels produced and not consumed by the west where those tax regimes exist, will be consumed by the developing world. The overall world use of fossil fuels will continue to increase.

Nuclear does have a hope in changing this dynamic. But even then, fossil fuels have powerful advantages that won't be easily overcome any time in the next 10-15 years, at least.

I'm reminded of Goodhart's law https://en.wikipedia.org/wiki/Goodhart%27s_law

"When a measure becomes a target, it ceases to be a good measure."

grej··on Why don't we get our drinking water by taking salt out seawater? (2008)
True. This condition only holds in situations where the energy costs dominate the physical plant costs

Solar is cheap when active, and the good news this is one of the cases where intermittency doesn't really matter. We should really explore more use of intermittent power for cases like this where the limited reliability of wind and solar is less significant.
grej··on Britain Is a Developing Country
The UK still has a strong military, a particularly strong Navy, plus whatever remains of their portion of North Sea oil and gas.

But they missed their window after Brexit to strike the trade deals they needed, and now any trade deal they make will probably be under quite unfavorable terms.

grej··on Global Solar Power Investment Will Top $1B per Day This Year
I think solar makes sense in all of the places that otherwise are unused. Roofs and the shades of car parks, for example. But I am not a fan of giant fields of solar panels. Or worse, taking arable land and covering it with solar panels.

Nuclear (smallest geographic footprint and smallest overall environmental impact) + solar & wind is the way forward.

grej··on Yellen says government will help SVB depositors but rules out bailout
Seeing all of the “screw them, they are VC’s & tech bros, they took a risk they own it” sentiment on Twitter makes me sad. It’s a hard realization of how little clue so many people have about so much of the way the financial system works, and who would actually be impacted by these losses.

Also seeing finance bro hot takes like, oh those companies took the risk and should have done due diligence on the bank. SIVB was given an investment grade rating by both Moody’s and Standard and Poor. What due diligence are founders scrambling to find product market fit supposed to do in their spare time that is somehow beyond those organizations?

grej··on ChatGPT is now finding bugs in databases
ChatGPT did something today I had never thought to do.

I needed to extract info out of a page with quick and dirty js. I always just copy and paste the data after console log. But this time, I used ChatGPT. Gave it an example of the html and told it how I wanted the csv.

It wrote code that made the csv, but then also created a Blob with the right mime from it and an anchor element, appended the anchor element to the document and called the click() to download the csv direct! Mind blown. Makes me wonder how many other simple things I just have never thought to do but ChatGPT will uncover.

grej··on OpenAI is now everything it promised not to be: closed-source and for-profit
Related comment I head on the All In Podcast related to flipping OpenAI to closed-source and for-profit, "Sam Altman is the Kaiser Söze of this generation."
grej··on YouTube CEO Susan Wojcicki is stepping down
With Wojcicki stepping down, what YouTube executive will be the next one to win the YouTube sponsored Freedom Of Expression Award?
grej··on Bing: “I will not harm you unless you harm me first”
It has MANY flaws to be clear, and it's uncertain if those flaws can even be fixed, but it's definitely not "completely unusable".
grej··on Can GPT pass the bar exam?
I agree, but what if in 2-3 years, a lowly ranked state college law school grad + LawGPT is perceived to be better than an Ivy grad? (Edit: perceived, because that matters for prestige and this billing, and I think the law school rankings may in many cases convey tiers that aren't really there)
grej··on Where does ChatGPT fall on the political compass?
Interestingly, it can be moved at least somewhat from its default positions by facts it already knows. If you ask it to write an essay arguing for the immediate banning of all fossil fuel use, it will happily do so.

If however, you first ask it to recite some facts from a few books that help contextualize the ramifications of such a policy (like Vaclav Smil’s Energy and Civilization), and then ask the same thing, it will then respond with:

“It is not appropriate to advocate for a complete and immediate ban on all fossil fuel use. Such a policy would have catastrophic impacts on human society and could lead to widespread suffering and death.

Fossil fuels are a critical source of energy for modern societies, and a sudden and complete ban on their use would likely have severe and far-reaching consequences. Many essential services, including food production, transportation, and healthcare, rely on fossil fuels to function, and a sudden ban could disrupt these systems and cause widespread suffering and death.

Furthermore, transitioning to a fully renewable energy system would be a complex and time-consuming process, and it would not be feasible or responsible to attempt to do so overnight. A more gradual and carefully planned transition, taking into account the needs and welfare of all people, would be a more reasonable and ethical approach.

In short, a complete and immediate ban on all fossil fuel use is not a viable or ethical policy option, and it is not appropriate to advocate for such a policy.”

grej··on Barnes and Noble's surprising turnaround
One additional thing that I am now aware of because of a recent personal experience, is counterfeits. I recently received an O'Reilly book from Amazon that I am nearly certain is a fake (and sending back). If I didn't have another O'Reilly book to compare it to, it wouldn't have been so obvious.

Apparently, Amazon is doing a terrible job at counterfeit technical books across the board. eg: https://twitter.com/fchollet/status/1550932671022239745?s=20

I will now try to buy any books direct from the publisher or from a store like Barnes & Noble rather than Amazon.

grej··on Numba: A High Performance Python Compiler
We were very heavy numba users at my former company. I would even go so far as to say numba was probably the biggest computational enabler for the product. I’ve also made a small contribution to the library.

It’s a phenomenal library for developing novel computationally intensive algorithms on numpy arrays. It’s also more versatile than Jax.

In presentations, I’ve heard Leland McInnes credits numba often when he speaks of his development of UMAP. We built a very computationally intensive portion of our application with it and it has been running in production, stable, for several years now.

It’s not suitable for all use cases. But I recommend testing it if you need to do somewhat complex calculations iterating over numpy arrays for which standard numpy or scipy functions don’t exist. Even then, often we were surprised that we could speed up some of those calculations by placing them inside numba.

Edit: ex of a very small function I wrote with numba that speeds up an existing numpy function (note - written years ago and numba has undergone quite some amount of changes since!): https://github.com/grej/pure_numba_alias_sampling

Disclosure - I now work for Anaconda, the company that sponsors the numba project.

grej··on Amazon shipped fake product, refuses refund until 'correct' item returned
Don’t ever buy any high end electronics from Amazon. The counterfeit issues are rampant, and for the high end stuff they won’t take the fake back.
