hahajk··on White noise improves learning by modulating activity in midbrain regions (2014)
Same with me, the music I normally like distracts me while I work. To fix it I open up a youtube tab with a "cafe sounds" loop running (while also playing my music). Then it sounds like there's some nice music playing somewhere in the distance but I can't make it out. I also open up a "train sound" loop, which really dials in my focus.

It's a bit of a cacophony, but it got me through grad school!

hahajk··on SpaceX reprioritized to cyber defense and overcoming signal jamming
You wouldn’t need anti-radiation missiles, you just need to detect the radiation using some kind of sigint system, then plot those points on a map and attack them conventionally.

I seem to remember that during the Crimea invasion, Russian used a similar tactic: they used sigint to find Ukrainian cell phone signals of soldiers hiding in the forests, tipping off the defenders’ locations.

hahajk··on Win32 is the stable Linux userland ABI (and the consequences)
Similarly, I was playing the recently released Humankind with some friends. My friends playing the first-party mac version were dealing with crashes every half hour, while I was playing through Proton completely issue-free.
hahajk··on Bringing the Framework Laptop to more of the world
Same, although I use Nixos with Pantheon WM.

Since it boots to desktop in 10-15 seconds I don’t have to deal with the overnight power issues everyone complains about. And since it doesn’t run a hundred automatic background processes it’s much quicker to start working than my MBP was.

Printing on the other hand…

hahajk··on Some argue that synthetic data can make AI systems better
The potential issue with using synthetic data to simulate the problem (like image classification) is that recognizing a lion in synthetic imagery and recognizing a lion in real imagery may also be very different tasks to a computer.
hahajk··on Difficult situation on campus: traffic jam of food delivery robots
We were walking past one of these robots whose wheel got stuck halfway off the curb, so it was completely stuck. My friend helped it back up, and it had a prerecorded voice say “thank you for helping me!” It was unexpected and delightful to be thanked by a robot, we make sure to help any we see that are in distress, even though we know they’re owned by a private company with profits in mind.
hahajk··on Anyone else feel the constant urge to leave the field and become a plumber?
Did this behavior start with the coda of Office Space or has it always been a thing?

A big aspect of Marxism is that labor has been alienated from their production in the age of industrialization, so I’d say it’s been a thing for a while.

hahajk··on Heart-disease risk soars after Covid, even with a mild case
I was going to ask if anyone knew how they found mice for these studies. Do they choose mice they have on hand that naturally have had heart attacks? Would those mice be involved in other studies too?

But I ended up googling it and sort of wish I didn’t ask the question.

hahajk··on Where in the world are Trader Joe’s warehouses? (2015)
If you’re interested in learning about how they choose locations, Freakinomics did a good episode where they cover just that. In short, they look for inexpensive locations that are rising in value, with demographics that have high education but relatively low income. (so, like, English majors.)

hahajk··on Man found guilty of ‘grossly offensive’ tweet
Why does the caption of the picture say "Captain Tom: Man guilty of 'offensive' Tweets"? He's the target of the tweet not the one guilty of it, correct?
hahajk··on Everything must be paid for twice
Maids and cloth-folding services are great, but a lot of people who have a whole lot of money but no time are working 60-80 hours a week (many work even more of course.) But you’re giving up more than money if you quit and take a 40 hour a week job. Jobs with fewer weekly hours often aren’t as glamorous and probably don’t have that feeling of “velocity”. Trying to take less than 40 hours a week and you’re probably not going to be a first class member of the company. If Bob takes off every Friday, how can he manage his full time team? And if a company tries to employ people at 30 hours a week as policy, how can they possibly compete?
hahajk··on My self-hosting infrastructure, fully automated
Before I clicked I thought “man, a single config.nix for his whole system? this is going to be big…” But I’ve continually been surprised how little configuration you actually need to do in nixos. I’ve been planning on configuring Home assistant on an RPi myself, so this will help. Thanks for sharing!
hahajk··on When my wife developed Alzheimer’s, the story of our marriage kept us connected
I had a girlfriend in high school/college for four years; I’ve been with my wife for over 15. Looking back on my high school relationship I can say I was in love, if I know anything about love from my marriage. The same feelings of interdependency and shared identity. It’s popular to look at young people and think they can’t know love but my experience says that’s not true.
hahajk··on Apple execs: Let's take a 30% cut of Uber and Lyft's membership programs (2018)
I looked up Uber Eats Pass; it’s not an all you can eat subscription. It waives delivery fees and gives a percentage discount to orders. It’s more like a loyalty program you pay for, like Prime.
hahajk··on Show HN: OnlyRecipe.app – Remove clutter from recipe sites
That’s pretty cool recipe formatting, but man that site has the least appetizing food photography I’ve seen in a long time.
hahajk··on Microsoft Exchange stops passing mail due to bug on 1/1/22
What are other good self-hosted email server options?
hahajk··on 25-Dec. Shout-out to everyone else at work
There very specific times you can launch to establish desired orbits. Typically these windows only come once every month or two.
hahajk··on 5 Important Things to Do Before the Market Bubble Bursts
“Don’t be afraid to do nothing.”

The author doesn’t mention that his article is the latest in a long line of “bubble’s about to pop” articles that have been steadily written since around 2014. Sure the stock market is in a bubble. But I would be sad if I had spent the last 8 years waiting for it to pop.

hahajk··on A Quadrillion Mainframes on Your Lap
Well yes the author quipped about Minecraft, but I can’t be alone in that my job as a PM consists of a lot of email and word processing, tasks that we’re solves decades ago. But somehow Outlook demands millennia worth of 7090’s processing power to show me my email.
hahajk··on Addressing Common Concerns with a World Without Timezones
“it feels weird to wake up at 3 pm and work from 5 pm to 1 am.“

It feels weird to start work on Monday and get off on Tuesday. idk how we’ll deal with words like “tomorrow”.

Edit: i guess night shift people deal with it. But having worked night shift I can’t help but remember that time really revolves around the dayshift workers. “Tomorrow” to your night shift peers meant one thing, but to the world at large I always was explicit with which day I was referring to.

hahajk··on California tries to close the gap in math, but sets off a backlash
I thought that was what “closing the gap” was. In fact, in the podcast “Nice White Parents”, they’re explicit about that. It about preventing advanced classes and tutors so the achieving kids can commingle with the struggling kids.
hahajk··on Debit cards are hidden financial infrastructure
Amex pays me over a thousand dollars a year to use my credit card (which it takes from the merchants as fees.) I kinda feel bad about that, but I know those fees are built into the price and if I used cash or debit I’d still be paying the same price, just not get the reward.

But if they accepted lightning payments, I would pay them in BTC.

hahajk··on California tries to close the gap in math, but sets off a backlash
What is misleading about the headline?
hahajk··on MacBook Pro 14-inch and MacBook Pro 16-inch
It’s not just repairability. It’s that everyone in this thread says “Apple gave us hdmi! They got rid of the touch bar!” Maybe this falls under “upgradability” but the idea of Framework is that the user decides what to include. Like with FOSS vs proprietary software. If the developers remove a popular UI element, there’s a good chance you can add a compiler flag or find a fork with what you’re looking for. (This is the idea, but we’ll see if it pans out in reality. I don’t like Framework’s smooshed arrow keys; the idea is that I can switch that out to a 3rd party I like. The reality is that there is so far no 3rd party keyboard.)
hahajk··on A viable solution for Python concurrency
But what if we had both? What if Ruby was as fast as Java? What a wonderful world that would be!
hahajk··on Gmail password first character is case insensitive on mobile device
Is this implemented by Facebook holding 3 hashes of your password? It doesn’t save your actual password clear text (or encrypted clear text), does it?

A related question: when a password system tells me I need to change my password, and it has to differ by 3 letters from my previous password, is that system storing my password text rather than the hash of the password? Is that safe?

hahajk··on Apple requires account deletion within apps in AppStore starting January 31
was it… stamps.com? adobe? wsj? a gym?

Privacy.com is free, but I’d pay quite a bit of money for it, it has saved me hundreds of dollars.

hahajk··on Startup Ideas
Has it actually been demonstrated to be a gateway? It reminds me of the argument that playing GTA is a gateway to becoming an actual thug.
hahajk··on Rent The Runway S-1 IPO
Thanks, I forgot about that. But I found this from Investopedia about stock price and mergers/acquisitions:

In most cases, the target company's stock rises because the acquiring company pays a premium for the acquisition, in order to provide an incentive for the target company's shareholders to approve the takeover. Simply put, there's no motive for shareholders to greenlight such action if the takeover bid equates to a lower stock price than the current price of the target company. [1]

If the buying firm doesn’t need approval from the Class A shareholders, what would be their incentive to buy those Class A stocks at a premium?

[1] https://www.investopedia.com/ask/answers/203.asp

hahajk··on Rent The Runway S-1 IPO
So what exactly is the value of the Class A stocks beyond speculation? In the olden days it was dividends, but it seems most stocks now don’t issue dividends. Then I thought well, it’s the value of selling to a hostile takeover or, when the company is on the defensive, stock buybacks. But with these non-voting shares even that value is taken away.
