pqdbr··on Choose Postgres queue technology
> Sidekiq solves "What happens when a worker crashes?" by just not solving it. In the free version, those jobs are just lost.

I've been using Sidekiq for 11+ years in production and I've never seen this happen. Sidekiq (free version) has a very robust retry workflow. What are you talking about here?

pqdbr··on Choose Postgres queue technology
Same here. Sidekiq + Rails in a Rails app is a powerhouse, simple and reliable, but I do worry about losing the queue in Redis. It would be great to have that in Postgres as well.
pqdbr··on Birb: Programming with bird emojis
I honestly have no idea what I'm looking at, but I love it.
pqdbr··on I built a plane spotter for my son in minutes
I have the exact opposite impression: legacy Rails apps are usually a pleasure to work with if the developers followed the most basic framework conventions.

It's called "on Rails" for a reason.

pqdbr··on The great cancellation: why megabucks TV shows are vanishing without a trace
The article mentions shows being cancelled after they were made and ready to stream.

Even if nobody is going to watch it, if you already paid for the production and it’s ready, why not put it online?

pqdbr··on Show HN: Aviation navigation log on $20 receipt printer
Half a year ago I asked around about the price of a DA62 I’m Brazil and it would be in the range of 1.6M USD (8M BRL).

Did the price you quote (600k USD) was for the single engine model? If so, how much would a DA62 cost you in the US?

pqdbr··on Nearly half of the tap water in the US is contaminated with ‘forever chemicals,’
How many years of your life would you give up to save you the trouble of cleaning sticky pans every day?

Asking seriously. I don't know how many I'd give, but it's definitely greater than 0.

pqdbr··on Gping – ping, but with a graph
Really nice that it allows you to pass a list of hosts at the same time, and it will plot them in the same graph:

For instance, `gping mydomain.com google.com` is really nice for a quick sanity check (is it my Wifi or my hosting provider).

pqdbr··on Case study: Algorithmic trading with Go
If you read the entire article, chatGPT is mentioned as something that increased OP's productivity 3x.

Isn't the trend detection equally applicable to shorting as well, with swapped signals?

Or do you believe there are more fundamental changes needed so your app can trade in shorting as well?

pqdbr··on Rubio Says He’s Heard Shocking ‘Firsthand’ Accounts of UFOs
You are changing the reference from the whiteness to Rubio.

Rubio didn’t claim he saw first hand accounts himself; the ones that talked to him did.

pqdbr··on Minimal downtime major PostgreSQL version upgrades with pg_easy_replicate
Let's say I have a Rails app and I want to do a major postgres version upgrade using this tool.

I see one of the requirements is that 'Both databases should have the same schema'. How should I manually load the schema to the new database (running on port 5433 for instance)?

pqdbr··on VanJS (Vanilla JavaScript): smallest reactive UI framework
This is hilarious. I lost it at the empty line for loading it in production.
pqdbr··on Two students built an A-bomb (2003)
Slightly off-topic, but the upcoming Oppenheimer movie from Christopher Nolan is looking to be a masterpiece. Can’t wait for it.
pqdbr··on Apple, Goldman Sachs Debut Savings Account with 4.15% Annual Yield
I'm not from the US, so please don't mind if the question is stupid: are these options all FDIC insured?
pqdbr··on Dishwasher Salmon
Please report back your findings, including the wife reaction (the most important part).
pqdbr··on Show HN: SiteGPT – Create ChatGPT-like chatbots trained on your website content
Same here. I know it hurts to offer a free trial for something that already costs you money to serve (those API calls won't be free), but it's really hard to sign up without trying it first.
pqdbr··on Defaulting on Single Page Applications
This article was the first time I learned about https://developer.chrome.com/docs/web-platform/view-transiti....

It looks really great, and I think Rails Hotwired / Turbo could really benefit from this API.

Of course, someone beat me to it: https://dev.to/nejremeslnici/how-to-use-view-transitions-in-...

pqdbr··on Eggspensive
Maybe it's possible to extrapolate the price difference to the entire store? I know it's a single data point, but maybe it reveals cheaper stores nearby than the ones you're currently shopping.
pqdbr··on After Alaska Airlines planes bump runway, a scramble to ‘pull the plug’
Why doesn't the plane weight itself? Couldn't there be sensors in the landing gear or something?
pqdbr··on After Alaska Airlines planes bump runway, a scramble to ‘pull the plug’
Let's say your target rotation angle is 10 degrees, so at the specified speed (called VR) the pilots 'rotate' the aircraft nose up by 10 degrees.

When they start the 'rotate' maneuver, the nose of the aircraft doesn't immediately go to (for instance) 10 degrees. It's a progression.

As soon as the nose starts pitching up (by 1 degree for instance), the aircraft is already generating lift to pull the aircraft up.

If the speed is set right (so you're fast), when you get to that 10 degrees angle of attack, your tail has already cleared the runway by a very safe margin, because you've been producing X lift from 0 to 10 degrees of rotation.

However, if your speed is set too slow, you're not generating as much lift, so the aircraft will be pulled up slower (you have been producing Y% less lift from 0 to 10 degrees of rotation). This means that by the time you reach your designated 10 degrees of angle of attack, you haven't cleared the tail yet, and it will hit the runway.

It’s literally right there in the first line of the description, yes.
pqdbr··on CustomGPT
I also though of this (prompt engineering), but I think that would hit the token limit pretty fast.

Page is down, but here is a description of the service by the founder himself:

Does anyone knowledgeable in AI know how feasible the claim of training your custom ChatGPT really is? Because this would be the holy grail we’ve all been waiting for, no?

pqdbr··on The best way to launch your startup [video]
Totally off-topic, but does anyone know what model of camera / lens I should buy to get this quality of image and bokeh effect at the background?
pqdbr··on Open Assistant: Conversational AI for Everyone
Would you care to add some context or you’re just throwing stones for no reason at all?
pqdbr··on Phone interview with Sam Bankman-Fried [audio]
I didn't lose a penny in the FTX debacle but even so it's infuriating to hear this crook giving this interview with the Bahamas waves as background noise.

Came here looking exactly for this. Thanks.
pqdbr··on Extremely Linear Git History
How do you constantly rebase on top of main if more than one person is working on the feature branch?
pqdbr··on Emergency SOS via satellite
From the article:

> A text compression algorithm was also developed to reduce the average size of messages by 300 percent

I don't think that's how percentages work.
