breput··on One Ka-52 helicopter deflected 18 MANPADS
"Deflecting" 18 older model Russian SA-16 Gimlets, which have been being phased out for a decade.

Take it or leave it, but Ukraine is claiming[0] they shot down two Ka-52 helicopters in the past week and there is photographic evidence[1] of one being heavily damaged (although still flyable) yesterday.

Also estimates[2] are that 25% of Russian's total fleet of Ka-52 helicopters have been shot down during the Ukraine war. "Russian attack helicopters have likely suffered particular attrition from Ukrainian man-portable air defense systems"

So maybe impressive but not an invulnerability shield.

breput··on Gandi.net – Pricing Update
There are value adds included in the price, such as DNS hosting and maybe email stuff, although some of that is going away along with the price increase.
breput··on Gandi.net – Pricing Update
The text in the link was sent to Gandi users via email today, although they purposefully buried the significant domain registration price increases with the GandiMail bs text.

The actual price increases are listed here[0].

For example, currently a .com domain can be renewed for $17.75/year (tax inclusive - I personally renewed a .com domain for the maximum of 4 years tonight). After the increase this will be $23.99/year (26% increase).

I've been a long time (sometime prior to 2007) Gandi customer and ignored previous discussion concerns[1], but this will be the last time I renew my domains with Gandi. The v4->v5 user interface change was painful at first, but they have fixed most of those UX issues - at least as far as the DNS support, which is all I really use. But their service is definitely not worth the premium.

breput··on The Cuboid: A DIY air purifier that's better than a box-fan (2021)
It's constructed using a regular 3 speed box fan, so it isn't going to be significantly louder than that and possibly quieter depending on how it is shrouded and insulated.

breput··on Ford EV Customers to Gain Access to 12,000 Tesla Superchargers
There are already a handful of Superchargers that have a CCS adapter built in[0]. Thanks to US federal money, some locations are already set up to charge both Tesla/NACS cars as well as CCS vehicles[1]. These will expand, but if either Hyundai and/or GM now switches to NACS, CCS is dead in the USA.

The physical layer is easy - mostly just plastic and metal contacts, as well as minor electrical differences. The reliability and payment layer is where Tesla has way outperformed and it will be interesting to see if Ford can support that with their "Ford Pay" system.

breput··on Ask HN: Hybrid or Full EV Car in Flyover States for 2023 (US)
There are nearly as many Supercharger locations along this route as there are in my entire state (more if you drive back through Portland[0]), and I live in a state with an area comparable to Washington.

breput··on Ask HN: Hybrid or Full EV Car in Flyover States for 2023 (US)
It looks like an easy trip, honestly.

ABRP shows[0] plenty of Superchargers along the route and a suggests only a total of 50 minutes of charging which are nicely spaced for eating and breaks, although I'd probably add a buffer in there as well.

Round trip[1] has more stops, obviously, but easily doable without any more planning than getting in the car and driving.

The i4 is a cool looking car, but maybe you could rent a Tesla from Hertz (the devil) or something like Turo and give it a try?

It is disappointing to see Yet Another California location added, although the voting system[0] does seem to be filling in some big gaps in lower traffic areas, like Kalispell, MT.

But yeah, there are huge gaps in the Dakotas, portions of Iowa, Kansas, and Missouri where one could not travel without some major planning or Supercharger alternatives.

breput··on Ask HN: Hybrid or Full EV Car in Flyover States for 2023 (US)
If you do a lot of short range commuting and have a way to charge it at home, a PHEV could work - but good luck trying to buy one right now.

Otherwise get a hybrid or Tesla, period. There are nice non-Tesla EV cars available but the charging infrastructure, even in high EV-density states, is unreliable. This should improve in the next 3-5 years but you can not currently depend on the chance of finding working CCS fast chargers to justify any non-Tesla option for road trips in many parts of the country. Also note that very few non-Tesla fully electric vehicles are currently eligible for the tax credit due to not being built in, or batteries sourced from, North America. Edit: [3]

I recently came back from a 1800 mile road trip across the central western USA in a Tesla Model Y and never had a moment of concern about the charging infrastructure, including rolling into a Supercharger at 4 AM with 2% state of charge and just knowing that it would work. There are definitely areas, mostly west of the Mississippi, with significant pockets without good Supercharger coverage[0] although with an adapter you can also charge Teslas at CCS stations or even at RV parks.

If you want to see how your situation might work, A Better Route Planner[1] and PlugShare[2] are good resources for being able to specify your car and route and see how an EV may work for you. But honestly, just get a Model Y Long Range with the full $7,500 tax credit and enjoy!

breput··on Drug shortages have worsened and may only increase in the future, experts say
FDA drug approval should include a clause that requires a certain production rate per quarter along with an ongoing adjustment based on the number of prescriptions.

If the applicant misses the production rate for one quarter, they agree to work with a second source drug producer to prepare for production. If they miss the next quarter's quota, the second source is allowed to sell the drug for no less than three years.

breput··on Companies hide negative news with unrelated press releases alongside SEC filings
The entire public sec.gov site, including filing data, is served from the Akamai CDN.

But there is also an AUP (https://www.sec.gov/os/accessing-edgar-data) which limits the number of requests per second, which in reality is quite a bit less than is documented.

breput··on Hard feelings over mission change for NASA’s Pluto spacecraft
"There’s going to be a boarding party on the first of October next year,” says Alan Stern, the mission’s principal investigator"

I think the unstated is that the original group of scientists feels like they are being put out to pasture in favor of a new set of researchers. But as you mentioned, if there aren't any more Kuiper belt objects on the "horizon", it seems like the right move.

breput··on Show HN: PineTool – An iOS Companion for the Pinecil
Note that only the newer V2 model has the BL-706 chip with BLE capabilities. The original V1 model uses a different chip without this.

And yes, you now need to worry about which CPU your soldering iron has!

breput··on How To Get Started In Soldering
I was thinking this same thing - get a good T100-ish iron (preferably a Pinecil[0]), a 60W USB3 power supply, some good 60/40 solder, and you're at least 90% of the way to a real professional soldering station.

breput··on Cash Stashed in Money-Market Funds Not Banks Fuels Recession Risk
Are the banks not totally to blame here?

Sure, there are primarily online/sketchy banks that are offering introductory savings account rates that are comparable to a decent money market fund's returns. But your Bank of Americas or your Wells Fargos or your First National Bank of South Cackalacky have been happy offering tenths of a percent interest for several years.

You'd have to be lazy, very paranoid, or a fool to leave significant money in a bank's savings account.

breput··on Llama.cpp 30B runs with only 6GB of RAM now
Yes, the 30B model is working for me on Windows 10 / AMD 5600G CPU / 32GB RAM, with llama.cpp release master-3525899 (already one release out of date!), in PowerShell, using the Python 3.10 version that automatically installs when you type "python3".

I did the following:

1. Create a new working directory.

2. git clone https://github.com/ggerganov/llama.cpp

3. Download the latest release from https://github.com/ggerganov/llama.cpp/releases (note the CPU requirements in the filename) and unzip directly into the working directory's llama.cpp/ - you'll have the .exe files and .py scripts in the same directory.

4. Open PowerShell, cd to the working directory/llama.cpp, and create a new Python virtual environment: python3 -m venv env and activate the environment: .\env\Scripts\Activate.ps1

5. Obtain the LLaMA model(s) via the magnet torrent link and place them in the models directory. I used 30B and it is slow, but usable, on my system. Not even ChatGPT 3 level especially for programming questions, but impressive.

6. python3 -m pip install torch numpy sentencepiece

7. python3 convert-pth-to-ggml.py models/30B/ 1 (you may delete the original .pth model files after this step to save disk space)

8. .\quantize.exe ./models/30B/ggml-model-f16.bin ./models/30B/ggml-model-q4_0.bin 2

9. I copied the examples/chat-13B.bat to a new chat-30B.bat file, updated the model directory, and changed the last line of the script to: .\main.exe

10. Run using: .\examples\chat-30B.bat

https://github.com/ggerganov/llama.cpp#usage has details, although it assumes 7B and skips a few of the above steps.

breput··on Why Firms Are Struggling with the U.S. Economy’s Soft Landing
To be clear - and there is no easy way to say it - the proposed Iowa law allowing 14 year olds to work in meatpacking plants is not designed to allow the politician's children to work there.

It is 100% designed as a gift to a major industry in the state to avoid fines[0] when they knowingly employee underage immigrants, primarily Hispanics from Central American, who are easily exploited both in pay and safety.

"On top of that, Senate File 167 would also free businesses from civil liability if a teen gets sick, is injured or killed on the job due to the company's negligence or the teen's negligence. The businesses would only be liable for "gross negligence and willful misconduct"—a much more difficult thing to prove in court."[1]
