lukevp··on Answering questions about Android developer verification
So this is saying you have to have an Android developer account and sign the app with your identity… so a one-time $25 cost and that’s it? You can still distribute and sideload apps as long as you sign them.

Microsoft does this for Windows apps if you don’t want scary warnings popping up everywhere. Apple doesn’t even let you sideload at all for iOS and for macOS they do the forced trash malware thing unless you run commands to allow the app in the terminal.

Am I missing how this is different from what we already have on most platforms? Is it because you can’t force it to install the apps? Is there not a developer mode that lets you install unsigned apps, or a way to root the device to install apps?

lukevp··on Rescuer at Fatal Tesla Cybertruck Crash Says Car Doors Wouldn't Open
Don’t ICE cars mostly catch fire under the hood or the trunk area under the car? Vs. the entire floor of the car being an explosive and very hot fire? Seems quite a bit different. I mean it sucks if a car catches on fire and burns up but if no one dies it’s significantly less of a big deal.
lukevp··on Organize your Slack channels by "How Often", not "What"
A 1 day retention? That seems suspiciously short and like it is intended to cover things up
lukevp··on Write the damn code
Yes, but… The AI has way more context on our industry than the raw programming language does. I can say things like “add a stripe webhook processor for the purchase event” and it’s gonna know which library to import, how to structure the API calls, the shape of the event, the database tables that people usually back Stripe stuff with, idempotency concerns of the API, etc.

So yes you have to specify things but there’s a lot more implicit understanding and knowledge that can be retrieved relevant to the task you’re doing than a regular language would have

lukevp··on Write the damn code
Autocomplete is a totally different thing that this article isn’t talking about. It is referring to the loop of prompt refinement which by definition means it’s referring to the Agent Mode type of integrations. Autocomplete has no prompting.

I agree autocomplete kinda gets in the way, but don’t confuse that with all AI coding being bad, they’re 2 totally distinct functions.

lukevp··on Microsoft Flight Simulator 2024 is coming to Playstation 5 on December 8th
The current graphics are good enough for the mainstream, and with modern SoCs, especially with AI frame generation and upscaling, can be run in a mobile form factor with low power requirements and still have great graphics. Hell, even my iPhone can run some games that look great, assuming they’re built with the hardware in mind.

Nowadays, a decent GPU (not even high end) is $700 whereas I can get a full console with a 120hz screen and built in controls for $450 (switch 2). That’s the mass market.

Consoles have traditionally been underpowered PCs but are shifting to a new product category. There’s no real downside to the portable form factor besides a lack of processing power; everything else is upside.

I’m here for it, I love handheld gaming.

lukevp··on I regret building this $3000 Pi AI cluster
60 cents per kWh? That’s shocking. Here in Oregon people complain about energy prices and my fully loaded cost (not the per kWh but including everything) is 19c. And I go over the limit for single family residential where I end up in a higher priced bracket. Thanks for making me feel better about my electricity rate. I’m sorry you have to deal with that. The utility companies should have to pay to cover those costs.

lukevp··on AI not affecting job market much so far, New York Fed says
“I’d like 2 cheeseburgers, and 4 fries. No mayo or mustard. Actually make one of them a double, and one with bacon. Oh how much if I make the first a combo?”

You think this conversation could be handled with the tech of 4 years ago? Siri can’t even turn off the lights and tell me a joke in the same request. Humans do not deliver all information in order (eg. The all the instructions refer to the burgers not the fries, but you only know that because you understand the essential nature of fries and what they typically include). That’s what AI in the drive thru is for.

lukevp··on The share of Americans having regular sex keeps dropping
No one means a BlackBerry when they say smartphones. It implies a large screen that can consume content easily, and with a large data plan, neither of which existed until The iPhone. I never saw someone watch 2 hours of YouTube on a blackberry.
lukevp··on Small Objects, Big Gains: Benchmarking Tigris Against AWS S3 and Cloudflare R2
This makes no sense. They ran the tests from a “neutral cloud provider”, as if someone is using AWS S3 to store their Azure and GCP data?? And they didn’t explain where exactly Tigris was running or how they controlled for the network latency. AWS is insanely faster when the compute is in the same region as the storage. They also didn’t mention what class of S3 they used or what replication settings (eg. S3 has express one zone).

I’m all for benchmarking and showing that your product is better from a technical standpoint. But at least for me, this is not the way.

lukevp··on How we exploited CodeRabbit: From simple PR to RCE and write access on 1M repos
The private key isn’t a key in the “API KEY” sense, it’s a key in the “public/private key pair” sense. It’s not sent to github and there’s no way for them to know if the signing of the token used to make the call happened in a secure manner or not, because github doesn’t receive the key as part of the request at all.
lukevp··on Lab-grown salmon hits the menu
The cost of the processes for these alternative meats astronomically outweighs the cost of ingredients, especially the cell culturing. It is unlikely that any of these companies are even making profit at this point. This is a long play to get the public to buy into this alternative food source, and only then will the scaling be enough to reasonably profit from any of this. There’s a baseline cost that they have to hit (farm raised salmon) and it’s incredibly cheap. Swapping out ingredients won’t make it cost competitive. Scaling up bioreactors might.

lukevp··on Fast
GitHub Desktop is way better for reviewing diffs than the git cli. Everyone I’ve ever worked with who preferred cli tools also did an add and commit everything, and their PRs always have more errors overall that would be caught before even being committed if they reviewed visual diffs while committing.
lukevp··on AMD CEO sees chips from TSMC's US plant costing 5%-20% more
Intel is more than just fabs. AMD spun off digital foundry forever ago and just uses TSMC, no reason Intel couldn’t do the same. At this point their fabs are a liability. They have a new leader who’s from a semiconductor manufacturing background so I have some faith they’ll give up on the pursuit of next gen fabs and focus instead on their IP. There’s a huge opportunity in their GPU segment. They’ve gone from a joke to competitive in a couple years, and they offer more VRAM for the dollar. They could tailor towards AI and really get some traction there.
lukevp··on TSMC to start building four new plants with 1.4nm technology
The implication I got from the GP comment is that the U.S. would be reluctant to have CCP manufacturing the processors due to the (proven) risk that they’ll modify and backdoor stuff.

If TSMC over invests in US factories then they could be taken over under imminent domain if Taiwan was no longer independent. So they have to keep a large portion of manufacturing domestic to Taiwan for lessened geopolitical risk.

lukevp··on It's rude to show AI output to people
Rather than close or ignore PRs, you should start a dialogue with them. Teach them that the AI is not a person, and if they contribute buggy or low quality code, it’s their responsibility, not the AIs, and ultimately their job on the line.

Another perspective I’ve found to resonate with people is to remind them — if you’re not reviewing the code or passing it through any type of human reasoning to determine its fit to solving the business problem - what value are you adding at all? If you just copy pasta through AI, you might as well not even be in the loop, because it’d be faster for me to do it directly, and have the context of the prompts as well.

This is a step change in our industry and an opportunity to mentor people who are misusing it. If they don’t take it, there are plenty of people who will. I have a feeling that AI will actually separate the wheat from the chaff, because right now, people can hide a lack of understanding and effort because the output speed is so low for everyone. Once those who have no issue with applying critical thinking and debugging to the problem and work well with the business start to leverage AI, it’ll become very obvious who’s left behind.

lukevp··on I convinced HP's board to buy Palm and watched them kill it
Windows phones were incredible, the OS was the most responsive at the time by far. No apps though. They were building in Android app support when they pulled the plug.
lukevp··on Show HN: Icepi Zero – The FPGA Raspberry Pi Zero Equivalent
I have no idea about this product category but am interested in learning more about FPGAs. What is the ballpark price point that something like this would be? Are we talking $100 or $1000?
lukevp··on Run GitHub Actions locally
Each job runs on a separate runner. If you want to pass data across, use artifacts to upload and then retrieve the specified file(s).
lukevp··on The principles of database design, or, the Truth is out there
Can you explain this a bit more or link to something? I don’t really understand. What’s encrypted? A guid? A monotonic integer ID? Is the encrypted ID only used for user facing stuff? How is it decrypted? What do you gain by this?

ChatGPT just announced embedded shopping. Sounds like another name for ads to me.
lukevp··on xAI has acquired X, xAI now valued at $80B
They started selling FSD back in like 2017 and it was supposed to be self-driving ALL THE TIME by 2019. It’s 8 years later now and the best you’ve got is “upgrade the hardware to version 4 and you can make a 25 mile commute without disengagement” when Tesla was promising cross-continent summoning so you could fly somewhere and your car would drive there to meet you, charging along the way. That’s L5 autonomy. The delta between promised and delivered is so far apart it’s ridiculous. Mercedes’ autonomous system is the only L3 even, Tesla’s is L2. They by my definition did not deliver whatsoever on their promises.

Another thing is a lot of people don’t even keep cars longer than 8 years (and people who are buying new, $100k electric cars are more likely going to upgrade sooner than someone who’s buying a $30k civic.) they paid for FSD thinking it would be ready soon.

lukevp··on Most AI value will come from broad automation, not from R & D
Huh? 40 hr work weeks are a recent thing, many people in history worked 12 hr days 6 days a week. Technology and social progress definitely leads to fewer work hours.
lukevp··on FOSS infrastructure is under attack by AI companies
Capitalism is an unthinking, unfeeling force. The writing is on the wall that AI is coming, and being altruistic about it doesn’t do jack to keep others from the land grab. Their thinking is, might as well join the rush and hope they’re one of the winners. Every one of us sitting on the sidelines will be impacted in some way or the other. So who’re the smart ones, the ones who grab shovels and start digging, or the ones who watch as the others dig their graves and do nothing?
lukevp··on Apple restricts Pebble from being awesome with iPhones
The ultra only needs to be charged for like 45 mins every couple days. It’s nice for the “find my phone” button and for getting alerts when my phone is in my pocket.

What it means is in any given year, you have a 1 in 10,000 chance that a data loss event occurs. It doesn’t stack like that.

If you had light bulbs that lasted 1,000 hrs on average, and you had 10k light bulbs, and turned them all on at once, then they would all last 1,000 hours on average. Some would die earlier and some later, but the top line number does not tell you anything about the distribution, only the average (mean). That’s what MTTF is; the mean time for a given part to where it has a greater likelihood to have failed by then vs not. It doesn’t tell you if the distribution of light bulbs burning out is 10 hrs or 500 hrs wide. it’s the latter, you’ll start seeing bulbs out within 750 hrs, but if the former it’d be 995 hrs before anything burned out.
