drtz··on You can no longer Google the word 'disregard'
I tried with a couple other AI search tools and got much better responses. Google sucks here. Bad title? Yes. Real issue? Definitely.

drtz··on News outlets are limiting the Internet Archive’s access to their journalism
> The current state of AI affairs is a lot about outrightly selling some one else's intellectual property.

Blocking archiving in a flailing attempt to keep AIs away is extremely shortsighted. Archiving is important for keeping historical context, especially when it comes to news and journalism.

Some people -- many people, actually -- use em dashes in their writing. Real people even use contrast to make a point on occasion, believe it or not. It's not AI writing that bothers me, it's the constant complaining about the supposed tells that prove something is AI-written.

drtz··on No more JetBrains products for me
Similar situation here. I primarily bounce between TypeScript, Python, and occasional Java -- all very well supported by JetBrains IDEs.

I occasionally try switching editors, most recently to vscode, but between the near flawless vim emulation, refactor functionality, and multi-language support I always come crawling back to JetBrains, despite the memory bloat and occasional buggy release.

Maybe that'll change someday, and I honestly hope something better comes along, but for now it just works better for my workflows and is worth the cost of admission.

> Also Jetbrains IdeaVim plugin is the best vim emulation I’ve seen. Nothing comes close with vim plugins support, vimrc, and what have you.

Once every year or so I get annoyed with a bugged JetBalrains update or memory leaks. IdeaVim has been one of the main things pulling me back to JetBrains for a while now, although the neovim extension in vscode is also very good these days.

drtz··on Meta to receive $3.3B in tax breaks for its $10B Louisiana data center
Providing tax breaks for construction that provides real, tangible benefits is one thing. Usually the argument is that a factory of some sort will provide long-term employment for residents.

What's the argument for a massive AI datacenter that employs very few people, strains infrastructure, and has the stated purpose of doing work that people had been doing, presumably reducing employment?

drtz··on Meta to receive $3.3B in tax breaks for its $10B Louisiana data center
There's a lot of ground between gifting $3.3 billion in tax incentives to a megacorp for a short-term increase in construction employment and allowing a homeowner build a second dwelling on their lot.

Incidentally, that same $3.3 billion could build around 10,000 accessory dwellings in Baton Rouge.

drtz··on Removing the modem and GPS from my 2024 RAV4 hybrid
> surely as far as the carrier is concerned, all traffic from the mobile device is the same

Going on a bit of a tangent, but deep packet inspection can identify packets routed using NAT, so if the phone is operating as a typical hotspot it would be identifiable by your carrier. Carriers in the USA used to block / denylist / charge extra for tethering using this exact approach.

drtz··on The quiet resurgence of RF engineering
I left a career in RF and analog design about 15 years ago to go all-in on software. I liked technical aspects of hardware design, but the workplace culture was very lacking to say the least.

Hopefully things have improved since then, but my perception at the time was that engineers in the field were paid and treated quite poorly compared to software engineers, despite having a significantly higher barrier to entry in engineering difficulty and technical knowledge.

drtz··on 'Hairdryer used to trick weather sensor' to win Polymarket bet
> If the actual temperature at the airport is important to any set of users enough so that the difference between it being 18 or 22 deg C is relevant, one should expect that there be at least 3 sensors

Three sensors doesn't solve the problem. Manipulating becomes marginally more difficult with three sensors, but it's still very possible, and with enough monetary incentive it's still even likely that it happens again.

So why not 5 sensors? How about 10?

And what about more consequential issues like the toppling of governments or military blockades where true redundancy is impossible and people are actually harmed?

Is there not a point where you start to blame the incentives that are being chased?

drtz··on Data centers in space makes no sense
The same radiative (radiant) cooling on Earth works almost just as well, but without the cost of a rocket launch.
drtz··on Data centers in space makes no sense
Not only is it not cost-effective, it's pointless (in this context).

Radiators works almost just as well on Earth. Convection and conduction more than make up the difference.

drtz··on Data centers in space makes no sense
> It sounds hard but it shouldn't not make sense.

It does not make sense.

The question isn't "can you mitigate the problems to some extent?", it's "can you see a path to making satellite data centers more appealing than terrestrial?"

The answer is a flat out "no," and none of your statements contradict this.

Terrestrial will always be better:

1. Reducing the cost of launches is great, but it will never be as cheap as zero launches.

2. Radio transmissions have equally high bandwidth from Earth, but fiber is a better network backbone in almost every way.

3. Radiation events don't only cause unpredictable data errors, they can also cause circuit latch-ups and cascade into system failure. Error-free operation is still better in any case. Earth's magenetosphere and atmosphere give you radiation shielding for free, rad-hard chips will always cost more than standard (do they even exist for this application?), and extra shielding will always cost more than no shielding.

4. On Earth you can use conduction, convection, AND radiation for cooling. Space only gets you marginally more effective radiation.

5. Solar is cheaper on the ground than in space. The increase in solar collection capability per unit area in space doesn't offset the cost of launch: you can get 20kW of terrestrial solar collection for around the price of a single 1U satellite launch, and that solar production can be used on upgraded equipment in the future. Any solar you put on a satellite gets decommissioned when the inference hardware is obsolete.

And this ignores other issues like hardware upgrades, troubleshooting, repairs, and recycling that are essentially impossible in space, but are trivial on the ground.

drtz··on Researchers map where solar energy delivers the biggest climate payoff
Also, fwiw, we've had an HSR project in the works in Texas for a couple decades now and have yet to even make a solid plan, much less break ground.
drtz··on Researchers map where solar energy delivers the biggest climate payoff
The fact that Brightline can take you from Miami to Orlando is wonderful, and I'm really happy Florida is embracing more efficient, less dangerous, and less stressful forms of transportation.

But using it to make a subtle jab agains CAHSR isn't really fair -- they're two very different projects (for one of them, it's genuinely a stretch to call it "HSR") in two very different regions.

Yes, it's harder to get big projects through the red tape in California than it is in West / Panhandle Texas or Central Florida. Go take a drive through those regions and you'll quickly see some reasons why, besides just NIMBYism, Californians are a bit more protective of their landscapes. If a massive wind project were proposed across large swaths of the Texas Hillcountry, you'd see a lot more push-back.

drtz··on Amazon Sued over Prime Video Ads: Class-Action Suit Alleges Deception
I consider myself lucky to have discovered how little value Prime has for shipping a few years ago when Target had a free Shipt promotion. I learned a couple things pretty quickly after I dropped Prime:

1. In most cases my Amazon orders took about the same amount of time to get to my house as they did with Prime: 3-4 days

2. Amazon has some terrible dark patterns. For example, on the product page you always see the lowest priced shipping option (usually free), but at checkout it defaults to paid shipping. It's really easy to accidentally pay an extra $5.99 for shipping, often with the same estimated arrival it would've had with free shipping.

drtz··on Amazon Sued over Prime Video Ads: Class-Action Suit Alleges Deception
> We can. You just have to make it first.

But how? I don't have the resources to build something like this on my own. I'm skeptical I could convince many investors to give me money to build something pitched as "just like Prime Video but without the ad revenue" when Amazon has certainly already done market research and determined this is the best path to maximize profit.

Thanks for sharing that NYT article.

> ...critics say that the use of sponsorship could make cable programmers more vulnerable to censorship or control by advertisers, particularly in light of recent efforts by organizations such as the Moral Majority and its offshoot, the Coalition for Better Television.

40+ years later I think it's pretty clear this was an accurate prediction.

> A much-cited - and widely disputed - study by the Benton & Bowles advertising agency found that the public would accept advertising if it meant a reduction or a holding-of-the-line on subscription fees...

This is great until a year later when YoY revenue growth is flat and prices are increased anyway.

I think this was just a short reprieve from ads in some spaces as we were adopting new tech, not a norm that is just recently being broken. Cable TV, newspapers, magazines, and even many taxis and municipal buses have had advertisements for decades.
drtz··on Amazon Sued over Prime Video Ads: Class-Action Suit Alleges Deception
Here's where I'd normally complain about how our economic system requires prices to increase while product quality degrades to ensure ever-increasing profits for shareholders.

Instead, I'll complain about commercials: why can't we just have something that's truly paid and ad-free? Do we actually value our time less than advertisers do?

I had the same thought: this is "tough?"

No fines for failing to protect your data? No additional requirements for data security? They just have to tell you when the screwed up.

drtz··on Thousands of AI Authors on the Future of AI
I'm of the opposite opinion. I think there's some Dunning-Kruger-like effect at play on a macro scale and it's causing researchers to feel like they're closer than they are because they're in uncharted territory and can't see the complexity of what they're trying to build.

Or maybe I'm just jaded after a couple decades of consistently underbidding engineering and software projects :)

> The Onion couldn't come up with this. It's so embarrassing. And yet, as I type this, dozens of people are taking this premise seriously and debating it on its merits. Humans really are doomed.

Personally, I find discussion about hypothetical, albeit completely impractical, ways we could avoid killing each other a much better use of time than a lot of other topics, like discussing ways we could kill each other more efficiently.

drtz··on We are retroactively dropping the iPhone’s repairability score
> I can tell you for certain this is what they're trying to combat.

> There are ways to implement this without the need to do per-device pairing, but doing so in a secure way is quite difficult.

Is this based on first-hand knowledge? I'm skeptical on both fronts because I neither see any evidence this is what's being combatted, nor do I see the technical difficulty of being able to self-authorize your phone's parts to be used in repairs.

Sure it takes some engineering effort to get there, but I wouldn't expect it to be particularly challenging from a technical point of view. The phone is already linked to a user account, and the phone's parts are apparently already linked to the phone that's currently using them.

drtz··on California's plastic bag ban is failing
Can't speak for California or LA, but in Dallas we had a plastic bag ban for a short period and it was sold as a way to reduce local litter, not reduce greenhouse emissions or protect the climate.

I didn't realize how effective it was until about 6 months when I was walking Downtown and noticed a plastic bag tumbling down the street. Prior to the ban, they were a regular sight and nothing I would have taken note of.
