Which is fine. Burn your tokens (with all the carbon emissions they generate in data centers) doing more involved tasks like that. Don’t waste it on silly, easy things like simple macros, search/replace, etc. AI doesn’t need to be a hammer used for everything.

If the original source is 44.1KHz, and this codec prefers 48KHz, is there an issue up-sampling to 48KHz before doing the AAC encode?

I think that's really the question with this work: up-sampling to 48k, not down-sampling to 44.1k.

Smart TVs are always monitoring what you’re watching by taking screenshots and processing them. This is a known thing for at least several years now. The only safe way to use a smart TV is to never connect it to the network, and use another streaming device. That separate device will spy on you too, but at least you’re making the choice.

My setup is: dark mode, color filters tint red, brightness 0, and reduce white point. It’s almost completely unusable in regular lit rooms, but nice in complete darkness (mostly apps like Instapaper).

The main issue I have is that blue text is unreadable. I wish you could stack color filters like grayscale first, then red tint.

I think a lot of developers (e.g. the HN crowd) aren’t aware that pretty much all non-IT businesses people, from receptionists to the C-suite, really do think that what IT people do is take their (business people’s) brilliant, fully formed ideas, and just convert them into “computer language” so the computer does them by magic. There’s no understanding (or desire to) that almost the whole job (of development) is trying to figure out all the assumptions, corner cases, logic conflicts, etc. that are embedded in their “requirements”. This is why IT is always seen as just an overhead cost to cut as much as possible: because you’re not perceived as actually knowing anything about the business, only as a rote translator which can be done by anyone.

Maybe it’s better to start in a smaller, more focused and less controversial topic to set some precedents before trying to boil the ocean.

This is about how 401ks and pensions are going to be forced to buy into (or very close to) the IPO. That affects “most Americans” whether they want to participate or not.

It depends on the firmware running on the SSD, so theoretically it’s possible but practically it’s not. Instead, SSDs use a special command to zero all cells on the chip at once, so it’s all or nothing. You can’t target specific files.

Yes. All of the assumptions made with shred and sdelete apply only for spinning HDDs. SSDs require different methods of wiping.

That assumption has come up in almost every conversation I’ve ever had with semi-technical people regarding git, so the confusion is just a fact. It happens so often, I think Linus (or whoever controlled the git trademarks at the time) should have demanded GitHub change their name when it was launched.

What if you have a few local machines you’re using for development, and want to keep them in sync? This method allows that single central repo without having to bounce all the code through a cloud hosting service.

It may have been (probably was) a conscious choice illustrating how new things were (i.e. those people didn’t grow up typing to a level where it was muscle memory). Also, keyboard layouts on early machines were far from standardized (other than the qwerty letters, almost every other symbol was not in a standard location from machine to machine), so even if you knew one machine you might not know others.

Most actors and directors put a lot of thought into small details like this, so when you see something like this it’s often intentional.

As the models keep improving, wouldn’t you be able to task a newer AI to “clean up this mess”?

They’re not describing any kind of burnout; just fatigue from working or being overstimulated. Taking a break a the exact remedy for this condition, but many people take breaks in a way that’s not actually restorative (phone scrolling, etc.)

OpenWRT updates are very much discouraged on an ongoing basis primarily because most devices running it use very cheap flash chips which are small and fail quickly after too many writes. They’re nowhere near the level of SSDs, or even SD cards, that can handle many flash cycles.

Almost as important is the fact that updates do not overwrite the original packages, because those are in a read-only partition. Updates are written to an overlay file system, so every updated package uses twice as much flash space. Installing updates weekly would quickly fill the flash.

But as far as vulnerabilities go, what’s the actual exposure? From the outside there’s no ports open, and on the inside only a few for device management, and basic services like dhcp, etc. Those have been around for decades and are pretty well hardened by now.

Pricing for any item is set by one thing: what people are willing to pay for it.

If a business raised prices because of tariffs, and consumers paid the higher price, that was a successful test that consumers are willing to pay that higher price for the item. Once that’s been established, the business has little incentive to lower prices once the tariffs go away. Prices only go down if competition with other companies pushes them down, but every player in a market has little reason to do so when they’re enjoying the higher profits.

Figuring out how to document stuff for others forces you to think things through at a deeper level yourself, and that’s the main point of the idea being presented here. Forcing yourself to organize your own thoughts is where the personal growth comes from.

The juice is still much less healthy. It’s the act of having your guts extract the nutrients that makes fruit healthy, because it reduces how quickly your body absorbs it. Once you make it into juice (or a smoothie) by mechanically digesting it prior to consumption, you’ve removed the need for that.

Zip drives arrived at exactly the same time as digital art, the web, and most importantly Macromedia Flash. Maybe the CS people with a few source code files didn’t fully use the space, but the art kids certainly did.

There simply was no other option at the time than Zip drives. Others did not strike the right balance of price, capacity, responsiveness, etc. Maybe Iomega paid to get them installed, I don’t know, but there really was no other option so I can easily see schools buying them just because they needed a solution.

USB thumb drives started appearing not long after, and they didn’t suffer from the click of death, so those became the preferred media by the time those people graduated school.
