Ask Lemmy@lemmy.world•how can i make my brain stop deleting whatever i study for an exam
2·1 年前Maybe try Anki ? It is specifically designed to help memorize stuff long term through spaced repetition.
You will need to create you own cards or find someone else’s cards. Later after learning a card, it will magically schedule a review at the best time to not forget it.
It really help me to learn vocabulary. (enable FSRS from the beginning)
Those are not deepseek R1. They are unrelated models like llama3 from Meta or Qwen from Alibaba “distilled” by deepseek.
This is a common method to smarten a smaller model from a larger one.
Ollama should have never labelled them deepseek:8B/32B. Way too many people misunderstood that.

AI@lemmy.ml•Is Stable Diffusion still best local image generation tool?
6·1 年前The hottest model now is flux, and the community is gravitating toward it after the failure of stable diffusion 3.
Tooling around it is still nascent and it is very demanding (12GB+ VRAM GPU highly recommended) so you could also start with Stable Diffusion XL, fairly mature at this point.

Green Energy@slrpnk.net•Study finds health risks in switching ships from diesel to ammonia fuel
2·2 年前The funny thing about air conditioning fluids, is that we are actually moving from HFC to propane and ammonia, due their green house effect.
Aka the thing that CFC were supposed to replace because they were safer.
It is a circle.

Technology@lemmy.world•Intel's CPUs Are Failing, ft. Wendell of Level1 TechsEnglish
7·2 年前This isn’t true anymore, Intel dropped AVX512 since they moved to Big+Small cores design while AMD actually implemented it with Zen 4.

Green Energy@slrpnk.net•Capturing CO2 With Copper, Scientists Generate 'Green Methane'
5·2 年前This could be useful for making synthetic aviation fuel at scale. Need methane + hydrogen + lot of energy.
Copper is abundant compared to the other rare earth catalysts, thus reducing cost.

World News@lemmy.world•The left-wing French coalition hoping to introduce 90% tax on richEnglish
10·2 年前The end result is that basically no one will be subject to this tax bracket.
It is high enough that everyone at that level will mainly get their real income from stock/loan which aren’t salaries.
Having this tax bracket or not having it is, basically the same for the super wealthy. The real method to tax them is through capital tax, not income.

World News@lemmy.world•Egypt pyramids: Scientists may have solved mystery behind constructionEnglish
11·2 年前They banned destrucive research for new rooms, because some researcher decade ago, enthusiastically drilled a bunch of holes to nowhere in order to do find them.
They still allowed the non destructive muon imaging a few year ago that heavily hinted to an unfound room.

Technology@beehaw.org•History says tariffs rarely work, but U.S. President Biden’s 100% tariffs on Chinese EVs could defy the trend, researcher says
2·2 年前The BYD Seagul at 12k$ is not really the type of car that could be successfully exported in western markets. The 30kwh battery is too small. I could see the upper trim with the larger battery being successful in Europe, but this is absolutely not going to work in USA.
A better comparison is the 27k$ made in china BYD seal vs the 38k$ made in USA Tesla model 3.
And also there is a massive price EV price war in China. I don’t believe any of their EV manufacturers is currently making money at those prices.
Even when they exports to lower income countries like Thailand, they are significantly more expensive.

Technology@beehaw.org•History says tariffs rarely work, but U.S. President Biden’s 100% tariffs on Chinese EVs could defy the trend, researcher says
21·2 年前A 100% tariff is simply way too overkill. At this point it is not a tariff, but a straight up ban.
The aim of a tariff is making a fair competition between local products and imports, ultimately to lower prices for consumers.
What has been done here, is pure protectionism for the US companies that didn’t invest enough in EV.
In the EU where we actually have Chinese competition, the cheapest EU-made EV (Citroën eC3) start at 23000€ and multiple models at this price point are coming in the next few years (Renault 5, VW ID2…)
If you already didn’t know, you can run locally some small models with an entry level GPU.
For example i can run Llama 3 8B or Mistral 7B on a 1060 3GB with Ollama. It is about as bad as GPT-3 turbo, so overall mildly useful.
Although there is quite a bit of controversy of what is an “open source” model, most are only “open weight”
Old french : esponge -> éponge (french) | sponge (english)
So far seem to be an uneventful upgrade.
Defaulting to wayland for KDE6 on a nvidia GPU doesn’t seem to have broken anything

World News@lemmy.world•New Zealand to seize black boxes from LATAM Boeing 787 as passengers recount incidentEnglish
1·2 年前Yes, in the EU the minimum recording time was recently increased to 25h. It is not a tech limitation anymore. What is actually limiting are privacy concerns from misuse of the longer recording.

Fuck Cars@lemmy.ml•Are microplastics from car tyres contributing to heart disease?
3·2 年前Pneumatic tires have always been made of vulcanised rubber though. Natural rubber is way too soft to hold up in this application.
Vulcanised rubber is a bio-based plastic, but being bio-sourced has nothing do with it being biodegradable. And vulcanised rubber isn’t.
There are bio-based-plastics that aren’t biodegradable, and fossil-based plastics that are biodegradable.

World News@lemmy.world•New Zealand to seize black boxes from LATAM Boeing 787 as passengers recount incidentEnglish
2·2 年前Black box were Solid State Drive before SSD were common, the advantages of no moving parts are simply too high.
Except PET from plastics bottles which is the only common plastic that is fully depolymerizable/ repolymerizable, instead of simply being remeltable.

World News@lemmy.ml•Biden Calls Chinese Electric Vehicles a Security Threat
2·2 年前Please do not use this map projection. It is unambiguously trash. It distord shapes way to much. There are much better equal area projections, like Eckert IV or mollweide






Worldwide diesel/kerosene biofuel production is too low. Last time airbus made a demo on 100% biofuel made from algae, they bought the output of a whole year to run a single long haul flight.
There is a reason they say Sustainable Aviation Fuel (SAF) and not biofuel. They also need e-fuel / synthetic fuel made from hydrogen in addition to biofuel.
