Searching for the reason of the "Shortage of air traffic controllers" led to

Industry insiders argue that many of the FAA’s challenges stem from Congress’s long-term failure to adequately fund the agency. The current shortage of air traffic controllers can be traced back to the 2013 United States budget sequestration, says Paul Rinaldi, a former 16-year air traffic controller at Washington Dulles International Airport and 12-year president of the National Air Traffic Controllers Association (NATCA). “They closed the air traffic control academy,” he explains. “They looked at reducing hours and many air traffic facilities. They looked at closing and cutting more than 100 federal contract towers, and stopped most modernization projects.”

Which led me to this chain of events:

The budget sequestration ( https://en.wikipedia.org/wiki/2013_United_States_budget_sequ... ), which was a set of automatic spending cuts in the Budget Control Act of 2011 ( https://en.wikipedia.org/wiki/Budget_Control_Act_of_2011 ), which was implemented to end the 2011 US debt-ceiling crisis ( https://en.wikipedia.org/wiki/2011_United_States_debt-ceilin... ), which was the newly republican House of Representatives starting their now recurring series of chicken-races about the debt ceiling, which had risen exceptionally fast due to the US stuffing all the private sector debt on their balance sheet during the handling of the 2008 financial crisis.

thulle··on AMD Ryzen APU turned into a 16GB VRAM GPU and it can run Stable Diffusion
With a 4090 nvidia-smi reports ~60-70% mem bandwidth usage while at 99% gpu usage, so that'd be 650-750GB/s. Considering how slow the inference is on the APU having 10% of the 4090 mem bandwidth maybe isn't that much of an issue?

edit: comment from the reddit thread:

> LLM isn't all that great as it is primarily memory bandwidth bound, ie almost no difference from a CPU if your memory bw is mere 12/25Gb/s. SD needs far more compute for inference - APU with slow memory helps.

thulle··on Car Prices Are Falling. Ford, GM Stocks Are Tanking
Stocks going down since prices aren't skyrocketing anymore.

---8<---

New- and used-car prices are up about 29% from the end of 2019, before the pandemic hindered production and reduced the supply of vehicles.

The prices for new and used cars are going down, if slowly. In July, prices fell 0.2% year over year, the third such decline in the past seven months.

thulle··on SanDisk’s silence deafens as high-profile users say Extreme SSDs still broken
Truenas recommends SSDs since half a decade ago or so due to the high failure rate. The forums felt pretty flooded with posts about failed USB-drives for a while there, and even before that I switched to installing on a SSD since I got tired of having a triple-mirror USB-setup just to keep the system alive long enough to be able to replace them (system was located across town back then).
thulle··on As ocean oxygen levels dip, fish face an uncertain future
> How did fish manage during the climatic optimum [1] some 8500 to 5500 years ago when it was between 1.5°C and 4°C warmer than it is now

From your wikipedia link:

---8<---

A study in 2020 estimated that the average global temperature during the warmest 200 year period of the HCO, around 6,500 years ago, was around 0.7 °C warmer than the mean for nineteenth century AD.

The HCO consisted of increases of up to 4 °C near the North Pole (in one study, winter warming of 3 to 9 °C and summer of 2 to 6 °C in northern central Siberia).[8] Northwestern Europe experienced warming, but there was cooling in Southern Europe.[9] The average temperature change appears to have declined rapidly with latitude and so essentially no change in mean temperature is reported at low and middle latitudes.

---8<---

So, the effect then was localized to the waters where there's more oxygen anyway, and having temperature going in different directions in different parts of Europe and at a much slower rate than current changes, would make it easier for the fish to migrate? Unclear how water temperatures behaved at different depths though.

> Although the Coast Guard released Subchapter M on July 20, 2016, vessels had two years to meet the majority of the requirements — the deadline falling on July 20, 2018. The Coast Guard is trying to work with the tug and towing companies to make for a smooth transition into the new regulations with minimal downtime. The entirety of the law will be phased in over a six-year period.

> The next deadline for obtaining a certificate of inspection (COI) is in 2019. By July 22nd, 25 percent of towing and tugboat companies’ vessels must have a COI onboard. The percentage increases by 25 percent each year after until all vessels in the fleet have their COI onboard.

thulle··on Greg Rutkowski was removed from Stable Diffusion; AI artists brought him back
I think Civitai, where the Rutkowski LoRa is hosted and where the screenshot in the article is from, in part set the tone during the earlier conflict with Sam Yang/@samdoesarts. I think Yang posted about someone on r/StableDiffusion making a LoRa trained on his work, which prompted Civitai to host a contest to see who could make the best samdoesarts-model. And send him a mail: https://files.catbox.moe/adyb0x.png

thulle··on 240W USB-C PD chargers are nearly here, says Framework CEO
I'd assume it's not specified as a upper limit but that it's just the highest voltage/current-pair currently defined.

On a more fundamental level, there's the physics of how much power you can pass through a cable/connector safely.

thulle··on Why the brain’s connections to the body are crisscrossed
I read some brain encyclopedia ages ago, so details are a bit foggy, but when the connections between the two hemispheres of the brain gets injured/damaged it can have some really strange effects. In the book they retold tests where they did things like showing a picture of a shovel to only one eye and ask the person to think of a garden tool, and they'd say shovel. Then they'd ask the person to explain why they're thinking of a shovel, and they'd tell some elaborate story like having met their neighbour a few days ago who said that they need to buy a shovel, or something similar. This due to the connection between the part(s) of the brain that constructs the story having severed connections to the parts the receives and processes the visual input of that eye. There was a few hundred pages of tests like these with wildly different effects depending on where the connections had been damaged.

Without injury the input should be shared just fine, but since the difference is so severe when the connections are damaged I guess (with no credentials or so to back it up) that there could be some hard-to-measure differences in thoughts formed depending on which eye is used.

thulle··on Fundamentally Understanding and Solving RowHammer
> Performance: using the same links above, we see that ECC ram tops out at 3200 MT/s, whereas for non-ECC you can get 4000+ MT/s. The brand selection is also better, which is critical if you want to get high performance memory chips like samsung b-die or micron E die.

Notable is that the max speed of 3200 MT/s for ECC is due to that being the fastest JEDEC standard for DDR4, you're not getting the XMP-profiles to run them faster and will have to resort to manual overclocking.

thulle··on Havana Syndrome was an “epic failure of science”
> The embassies actively sprayed in offices, as well as inside and outside diplomatic residences — sometimes five times more frequently than usual. Many times, spraying operations were carried out every two weeks, according to embassy records.

> There was also a correlation between the individuals most affected by the symptoms and the number of fumigations that were performed at their residence.

So, overexposure to nerve agents both in their homes and at work? Sounds like something decently easy to prove that it has occurred for most affected, and something that should be covered as some kind of work injury. I assume living quarters were provided by the employers.

thulle··on Ask HN: Do you use ECC RAM in your home/personal workstations?
> Not sure if its an AMD thing but my friend booted his EPYC server with 256GB of DDR4 ECC RAM for half an hour.

That could be a memory training issue. Using 256GB listed as compatible with the Supermicro motherboard my EPYC server boots in a minute or so. If i configure my workstation memory with weird timings it can take a while for the motherboard to figure out the remaining Auto-timings, possibly adding 4-5 minutes to the boot procedure.

> Speed and work throughput is of utmost importance so ECC I'd say is okay to be sacrificed.

But you don't have to, see my other post in the thread regarding my workstation memory.

thulle··on Ask HN: Do you use ECC RAM in your home/personal workstations?
> My impression was that you could expect extremely little OC to be stable even if you did it yourself.

Not my experience at all. I bought a Ryzen 3700X with 4x 16GB 2666MT/s Kingston ECC. Memory chips turned out to be Micron revision E, same as used in many popular Gaming XMP sticks.

I could run these at 3333MT/s and lower CL from 19 to 14. Thus, raw latency going from 19*2000/2666=14.2ns to 8.4ns. After recently buying a used Ryzen 5950X I can now push the memory to 3600CL14, or 7.77ns. At this point I'm at the limit of what I can cool without starting to hear my PC.

> What I could find was _very_ slow and something like twice the price.

And at this point I'm running my memory at the same speed as G.Skill Ripjaws V Black, which is the fastest gaming memory I could find available here, but the G.Skill is twice the cost. Though, I see that it's also available as 4600CL19, and I actually never tried decoupling the memory clock from the fabric clock after upgrading my CPU since I couldn't push 4 sticks fast enough on my 3700x that I'd make up for the decoupling. I should probably try it out. Suspect I won't hit 4600MT/s though, but I don't think I would be able to run the G.Skill att 4600CL19 with 4 sticks either.

thulle··on CoreFreq, a CPU monitoring software frequencies, ratios, C-states
The feature to show DIMM timings seem unique, I haven't seen that before. ECC DIMMs use the same ICs as regular memory but doesn't have the XMP/EXPO overclocking profiles, so I have to manually overclock them to get performance closer to regular RAM. Being able to have my benchmark/stability-test script write down the current timings in the log instead of having to write them down as I'm setting them in BIOS and later type them in would be an improvement.
