jsty··on Quality non-fiction books are the antithesis of AI slop
Perhaps not the same one, but there's a fantastic course by Barbara Oakley by this name. I viewed it quite a while back, but the modern incarnation seems to be [0]. In a similar vein, the book "How we learn" by Stanislas Dehane is also very good!

jsty··on U.S. war in Iran has cost $25B so far, says Pentagon official
Famously, they struggle with this one: https://news.ycombinator.com/item?id=42160768

jsty··on Why I don't have fun with Claude Code
Indeed, one of my favourite things about coding assistants is that I can now get an easy code review on my personal projects, or once I've thought through my approach have it think up alternatives I may not have stumbled on.

I've found it very unsatisfactory (both experience and results) to use them to replace code production. But in terms of augmenting the process - used to critique, explore alternatives, surface information - they're getting really quite handy.

jsty··on We need a clearer framework for AI-assisted contributions to open source
It feels like reputation / identity are about to become far more critical in determining whether your contribution, of whatever form, even gets considered.
jsty··on Writing a good design document
The AWS Lambda PR/FAQ was released late last year - worth a read

jsty··on Undergraduate Disproves 40-Year-Old Conjecture, Invents New Kind of Hash Table
Of course not - that would be ridiculous - it's clearly a job for a Mini-Me! ;)
jsty··on US and UK refuse to sign AI safety declaration at summit
> In the professional intel community they have been talking about this as a general problem for at least a decade now.

As in they've been discussing detecting clandestine AI labs? Or just how almost no activity is now in principle undetectable?

jsty··on The economics of the Birkin handbag
In economics terms - a Veblen good

jsty··on Tailscale SSH is now Generally Available
It's listed as available for the personal plan under "Compare Plans and Features" -> "Application Networking" on the pricing page
jsty··on Double-entry bookkeeping as a directed graph
When you reconciled the balance in your bank account / credit card statement against that in your set of accounts, you'd notice the error as the statement balance would be 1000 higher than reflected in your accounts.
jsty··on Bard is now Gemini, and we’re rolling out a mobile app and Gemini Advanced
FYI for any Googlers - On the "Sorry, Gemini advanced isn't available for you" page, clicking "Learn More" gives you a (presumably internal) SSO sign-on (links to https://support.corp.google.com/googleone?ai_premium)
jsty··on Curl HTTP/3 Performance
Looks like Cloudflare quiche:

jsty··on It's not microservice or monolith; it's cognitive load
> Monolith has implicitly replaced the word "Legacy" system

Indeed, one couldn't possibly recommend a Monolith in 2023/4. A macroservice on the other hand ...

Right. I'm off to polish my conference talk notes

jsty··on Tacit Knowledge Is Dangerous
Use an internal Q&A / Quora-style tool with good search. Trying to keep little snippets of info like that under useful MECE categories only ever ends in pain & frequent refactoring.
jsty··on Amazon EC2 Enhances Defense in Depth with Default IMDSv2
Then, as alluded to in the last section, you can link IAM to an OIDC identity provider to hand your workloads temporary role credentials

jsty··on Enterprise-Fu
> what is "enterprisey"?

> documentation over working software

In the spirit of no true Scotsman, you're not truly enterprise until there is a combination of barely working software and aggressively wrong documentation working in perfect harmony

jsty··on What we learned making a plastic injection mold with a Chinese mold maker
> I don’t know any field that charges by the half hour

Not that it detracts from your overall point, but some of the best paid knowledge workers on the planet - lawyers - regularly bill out in 6-minute increments.

jsty··on Language Models Represent Space and Time
I’ve watched Tenet and I’m not sure I can explain what happened either …
jsty··on CatalaLang/catala: Programming language for law specification
> What are the benefits of ambiguous laws?

That they can deal with the massive amounts of ambiguity & blurred lines / grey areas the world has to offer. Too many of our everyday concepts can’t be expressed rigorously for a formal encoding & determinate decision process - a famous example being obscenity’s famed “I know it when I see it” definition - and many are highly context dependent.

jsty··on Ask HN: How do you look for jobs in 2023?
Ah yes, getting sued as a service
jsty··on Your computer should say what you tell it to say
I don't get how this would be seen within banks as any different to the existing endpoint security offerings offering remote attestation that - by the same logic - they would already be mandating customers to use to access banking platforms, because doing otherwise would mean not being "as secure as possible" and getting dinged by the regulators.
jsty··on The next generation of serverless
> Even the cold start and memory benefits could largely be replicated for native code if you write a custom kernel ... people act as if lightweight isolation is fundamentally impossible without a JITted platform

I think when most people refer to this as being "impossible", they mean practically impossible, not dis-allowed by the laws of physics. "First write your custom kernel" is a step only a miniscule proportion of projects can justify.

As to unique capabilities - none of its capabilities are really earth-shattering in and of themselves. But together and combined with the fact the barrier to entry is so much lower than alternatives like custom kernels, it's quite understandable why people see it as bringing something new and exciting to the table.

jsty··on Twitter is being evicted from its Boulder office over unpaid rent
It sounds like Feb 2020 was when the letter of credit was arranged, not when it started to be drawn on
jsty··on Dell in hot water for making shoppers think overpriced monitors were discounted
> after a quick email, you can get a huge “discount” to show your boss. Just ignore the fact that you’re still paying 2-3x market value.

This is rampant across a lot of enterprise & mid-large B2B vendors because of purchasing departments getting evaluated on the %discount and not by any measure of value for money / market pricing. If purchasing requires a >20% discount to ok your deal, of course the incentive for the seller is to bump the price accordingly and see it waved through.

jsty··on Show HN: Arroyo – Write SQL on streaming data
In the watermarks documentation it mentions that events arriving after the watermark are dropped. Are there any plans to make this configurable (to disable dropping or trigger exception handling) and/or alertable?

I can think of quite a few use cases (particularly in finance) where we'd want late-arrivals to be recorded and possibly incorporated into later or revised results, not silently dropped on the floor.

jsty··on Targeted attack on our management with the Triangulation Trojan
That one of the bigger security companies seemingly didn't have MDM screaming bloody murder or outright blocking authentication for an endpoint this out of date is more than a little concerning.

Props to their SIEM for detecting it in the end, but this seems like it could've been detected and remediated a few weeks in (assuming it didn't also have the ability to spoof the iOS version).

jsty··on Europe’s biggest city council faces £100M bill in Oracle ERP project disaster
Building internal replacements for the subset of functionality you use would be less than half the battle.

Convincing your auditors that those systems were representing your financial position correctly would be hell on earth. Like them or not, auditors know SAP, Oracle and the like - and have well-defined processes & experts to certify them.

There's large amounts of risk and cost on both sides of the equation.

jsty··on Europe’s biggest city council faces £100M bill in Oracle ERP project disaster
With several orders of magnitude difference in workload / transaction size, and a lot more features in non-financial areas. Most accounting systems can do the bare essentials around inventory management, HR, etc. - but very few can run & form the system of record for, say, operations at the scale of an F500.

Whether it makes sense nowadays to continue stuffing these all into one system centred around the general ledger is left as an exercise to the reader.
