I bought Airpods soon after they came out, and got a pair of Airpods Pro just a couple of years ago as a gift for my girlfriend.

I just switched back to a pair of $50 IEMs (Tin T2 Pros) with a replaceable MMCX cable and foam tips. Fortunately I use a phone that has a jack.

The removal of the headphone jack is an absolute crime. Everyone I know struggles with Bluetooth regularly, but even the Apple models with special pairing chips don’t ALWAYS behave. Meanwhile, I do have to deal with a cable on these IEMs… but honestly, after 2+ years of suffering with Bluetooth, I’m more than happy with that tradeoff.

By the way, the headphones I have now are absolutely fantastic. Especially with the foam tips, noise cancellation is just about as good as my Airpod Pros, and I can either wear them like normal headphones, or hooked above the ear, to keep them more secure (mostly while running).

They’re also built out of solid aluminum like absolute tanks.

If anybody is skeptical about Bluetooth headphones, please seek out phones with the jack and try out something like these IEMs. I think you’ll be very happy.

If I’m allowed to branch to a separate topic, I think this is reflected in what I believe is a fundamental issue in larger social networks: moderation. It would solve so many problems (and introduce new ones, which can be solved) if, like email, it was by filters set both by user and server (assuming sufficient federation).

This could breed an economy of curation markets/algorithms. If you want to stick to a particular echo chamber, you could.

I heard someone who worked on a big budget sports game discussing this once. In simulating movement, there's a tradeoff between realism and responsiveness to player input. If you try for perfect realism, the controls will feel laggy and frustrating, because 100kg bipeds don't start, stop and change direction as quickly as we wish they could. On the other hand, if you decide to tweak things to increase the responsiveness, physics goes out the window and our brains can immediately tell that the resulting movements aren't realistic.

I'm buying housing for myself. It would be a potential relevant thing to take into account between choices, but I still need a house.

I'm buying a long term asset, so the liquidity of the housing market is not relevant to me, unless I'm actually buying for a specific short term, like a planned work period.

Liquidity of the housing market is only important to the agents and the loan originators because they make money on the flow.
Code Smell 106 – Production Dependent Code
I think you’re both right.

Taking some hopelessly byzantine, spreadsheet-driven process and “automating” it by building a Rube Goldberg scripting framework around it is the kind of totally stupid automation that doesn’t work.

Actually getting down to surface level and understanding fundamentally what each of those humans is accomplishing via those spreadsheets, extracting that all the way back out to a domain model and process flow diagram, and then selectively replacing process steps, whole cloth, with tech designed to be an actual subservice with SLA targets, is the right way to do it.

Throwing the spreadsheets and/or humans out altogether and starting “from scratch” is so exceedingly and needlessly risky from an information loss and hubris point that, well, good luck, but you’re nearly certain to fail.
When I was a kid, the tub in the bathroom had two knobs to control the faucet and shower: one marked with a red H, one marked with a blue C. Easy to understand, consistent with the faucets in the kitchen and bathroom sinks, easy to control. There was the little thing to pull up and redirect the flow from the faucet to the showerhead.

Every tub/shower fixture in the apartments I've lived in and all the hotels I've visited since has been different. They have all replaced this simple arrangement with some godawful thing that tries to combine the two variables of "amount of hot water" and "amount of cold water" into one knob/lever/dial/whatever. Usually with absolutely no markings. It takes an annoying amount of time to figure these out the first time and sometimes they remain annoying forever - the one in my current apartment is mounted at a weird angle, so "off" is slightly to the right of pointing the handle straight down; maximum hot water is somewhere below pointing straight right, and pointing straight right is cold. Pointing straight down is an annoying, chilly trickle.

Every time I take a shower I miss the simplicity of two knobs, clearly marked.

The humble handlebar-mounted bicycle gear shift. So much more pleasant than reaching down to a little lever mounted on the frame like I did before these became standard on even the cheapest bikes. Just move my hand over on the handlebar a little, grab, and twist: there's a little resistance, then a distinct click as it moves to the next spot, which changes the tension in the cable and makes the derailleur do its job of moving the chain from one gear to another. It is not perfect, but its failure modes are much more prone to "a little out of alignment and now you skip over a gear or two in the middle" than "it's super easy to shift the chain off the gears entirely". People have come up with other ways to alter the gear ratio between the crank and the wheel but they are all much more complex and power-hungry than the grip-shifter and derailleur combination.

If you want a specific brand and model of thing, my Tom Binh "Pilot" bag is really nice. Durable, reasonably cute, carries my computer and everything I need for a day going out to cafes to work, with enough room for a change of clothes or two if I stuff it tightly. Has some nice touches like a pocket in the center with a drain hole for a water bottle or a compact umbrella, and a pocket in the back that unzips on the bottom so you can empty it and slide it over the extended handle of your big rolling bag when traveling. I've had it for like half a decade and it's been my main bag for a lot of that time. https://www.tombihn.com/collections/travel-bags/products/pil...

Prolog is a declarative programming language. If you haven't tried it a bit already, you probably won't realize where it would be useful. I've seen that with friends on side projects, writing complicated rule resolver engines that they'd get for free if they embedded prolog into the project.

So you might consider learning the tool enough to understand when and where to deploy it.

Half the stuff is overstocked, half the stuff is out of stock because there is nowhere to stock it. This jumbled state actually seems more likely after a disruption, than purely empty shelves. For example, how many people's dwellings are currently loaded with a larger than usual amount of toilet paper and canned goods that they're working through? Businesses are going to have made similar misjudgements of what are critical staples and what is fluff that won't sell.

I'm solidly in the Austrian camp and had to buy a bunch of plywood this summer. But this price inflation narrative seems like half political meme, half telegraphing of corporate plans (like many anti-WFH articles). It's a motte and bailey - yes inflation is "high". But 10% price inflation would still only make a $30 sheet of plywood cost $33 over a year, not $80 over a few months. Unless we're experiencing hyperinflation, specific >30% price hikes are best described by the actual problem (supply chain) rather than playing up people's fears that such rises will happen across the board.
The totalitarian German government has for example ordered a long light lockdown of the asymptomatic just last year.

The maximal time needed for such a lock-down would be something like a month at most 2 months (Wuhan started the lockdown on 20. Jan, on 26. Mar there were no more cases), even without fast PCR testing nor vaccines.

With a fast PCR testing infrastructure, you might not even need to lock the people up.

And you don't need a world government to do that. There could be COVID-free bubbles vs the rest of the world.

Honestly, all the essential travels could tolerate a 3 weeks quarantine. Business could be conducted remotely. We have internet after all.

A very good friend of mine who was a semi famous video game designer in Hollywood for many years, said as soon as you hit 40, go work for the government. He works for the government, because of the stability, the benefits, all the things he was finding that after 35 years in the industry, he was just too old.

Over many conversations he conveyed to me that the technology industry is a young person‘s industry. Once you hit 40, you’ve got to find a way to progress to owner, senior management, or do something else.
I am in the B camp. It is probably less efficient in the long run but I personally find it more enjoyable and easier to learn and grasp new technology by jumping right into it and then refer to manuals and guides to accomplish the needed tasks.

The issue I frequently run into with this method is wasting time on less efficient tools and or rebuilding or starting over after gaining the knowledge I could have obtained first.

But I'm definitely in camp B as a sink or swim type personality.

> When school districts are coming up with lists of books by black authors or with civil rights subjects to ban them and cancelling black author appearances, and parents are explaining that they support such measures because they don't want their kid to feel guilty for being white or that it's all Critical Race Theory

But that is about banning topics, not being upset because your kid came home with a book by a black author. I agree that is bad, but that wasn't what this discussion was about.

> (Funnily enough I don't see such massive pushback when teachers set kids the objective of reading a book with a European author, or a book written over 100 years ago...)

Yeah, some of the pushback will be motivated by racism, but labelling all pushback as racism wont do you any favours.
> San Francisco now has more cases each day in the vaxed than the unvaxed

That's a common but meaningless way to compare vaccinated and unvaccinated case rates. It's a problem of class imbalance: 77% of SF residents are fully vaccinated (https://sf.gov/data/covid-19-vaccinations). Vaccinated people outnumber unvaccinated, so comparing absolute counts of new infections among these groups mixes the effect of vaccination with the effect of being the majority class.

Sticking to rate per capita within each group, positive tests are twice as common among unvaccinated than vaxxed. (Severe outcomes and deaths will be even more different.)

If that’s what we’re talking about, was weird to see Merriam-Webster swiftly adding a definition for “anti-vaxxer” that includes those opposed to vaccine mandates.

So apparently a person who is willingly fully vaccinated, believe vaccines work, and believes that everyone should get vaccinated may still be an “antivaxxer”.

That’s some Ministry of Truth level stuff.

> Archetypal market making involves simultaneously buying and selling an asset

Does it? I worked for a few years for a market maker, and that's not what we did. Simultaneous buying and selling is what the arb guys did. We'd buy and sell with generally short hold times. Which makes sense to me given that the exchange has market makers to provide liquidity. If something can be simultaneously bought and sold, then the market-maker is unnecessary.
A Dog Is Coming
Typical car tires are inflated to 35 PSI or so. There is a surprisingly large "footprint" from a tire supporting a car.

I think the PSI in their test is fairly small. While I'm sure finding an elephant is difficult, a simply hydraulic press in the lab could deliver hundreds of PSI.
To admit defeat
Sure, but the more important point is that the market represents housing. Having housing empty is pointless, so market speculation is that is not about the rent from the asset but only its capital growth leads to that exact outcome, empty housing has lower expenses and depreciation in reality, which helps maintain the asset's value better than if someone was living in it.
AFAIK: To discourage use of them, since HN wants the focus to be on link submissions.

One time I was in a foreign country but looking for hotels on Google Maps for a future weekend getaway in my home country. Despite being logged in and Google having my home address, and with each account needing a country to comply with differing data protection laws, it was still showing me prices for hotels in my home country in the foreign country's currency. Helpful? Not!
This is a valid question. Others have provided a much better answer, the thing I want to add is that being able to express computation in software the same way as in research papers makes the code much easier to read and reason about. This language was invented a long time ago to express computations concisely, and today you will see a lot of math built on top of these abstractions (since they’ve been around for sooo long).

So the ability to express computation in standard mathematical notation rather than having to invent pseudo symbols to do it makes it much easier to read for people who already have that training. And for people who don’t… it does require pre-reading to understand how these symbols are used but you have the benefit for hundreds of years of math literature and community to look it up!
That is probably true. Perhaps I should have said "If you are able to patch the machine code in a program object, you probably have full access to the system anyway".
Yes, coming from python it took a while for me to wrap my head around this.

Ask HN: What do you use to switch between projects
I work on multiple projects in the same time. Most of the sideprojects so I am working on them from time to time.

I would like just to resume from where I left. Not to open again everything.

And I am wondering what software is there (MacOS if possible) that allows me to switch between projects.

This means:
- Open Finder to a specific address
- Open IDE/Editor (different ones)
- Open Browser with some tabs to resume research
...

Is there a solution for this?

I have something in bash where if I cd to a folder it will execute a script that opens the browser, but I feel it is not complete.
Ultimately you have to build within your sphere of competence. If you have a well-established but inefficient manual process, it may sometimes be the case that burning it down and replacing it with a tech-driven approach might be the best way forward.

But if you are trying to solve a novel problem, and the proposed solution involves "ML will magically predict the future", you'd better have a very good idea of exactly how the problems will be solved, or else you're probably better off starting with good old-fashioned human intelligence.
> that's not what we did

Archetypal, not predominant.

> Simultaneous buying and selling is what the arb guys did. We'd buy and sell with generally short hold times

The ideal market maker is arbitraging (and eliminating the arbitrage-able inefficiency). That’s why humans were replaced by faster-trading machines everywhere they could be. In most cases, the arbitrage is synthetic or approximate, e.g. hedging an options or swaps book. But a fundamental separation between speculating and marketing making is the latter does not take a view on the assets per se, and should not be betting on their future price movement.

No market maker always achieves the ideal. But they tend towards it. Zillow didn’t have that tendency. In fact, they erected fundamental obstacles between themselves and that ideal.
>"The operators are actually really nice if you manage to learn them all well. It can make the code both very concise and readable."

This sounds suspiciously regex like. Concise it is, readable it is not. But regex is unique case and and harassing people with similar patterns in every line of code should be punishable by at least 10 years of maintaining complex software written in Brainfuck.
Visioun Newsletter Issue 3
To my taste, there are no problems with regular expressions at all.

But there are problems in all sorts of escaping. Without peeking into Stack Overflow, can you tell, how to escape properly in grep/sed? If it is running in bash/zsh? In cygwin? In your favorite text editor? In bash/zsh script? How many slashes would you need for an opening bracket? For a pipe?

You just never know. This frustrates heavily.

I don't even try to use sed or grep. Instead, I just write a small Python or Racket script to do the job. This is what I recommend. While learning Regular Expressions, just stick to your favorite programming language with RE support. Like Python or Perl. Use it for everything you need.

Then abide to a heavy burden of escaping in all sorts of exotic environments.
