- Comment on How does one become a entrepreneur? 2 hours ago:
The process depends on the country. But the main point: you have an idea and ability to make it happen.
Build it yourself, or hire someone and manage them - if you can get things done and make money of it, that’s the whole idea.
Usually people fail at thigs they do not know how to do. Being an entrepreneur means you should know how to do it or whom to hire and proptly pay to take care of the problem.
Taxes, finances, time management, idea, the ability to follow through, the ability to know what you need and to have an actual market for your product. - Comment on Why was Rock 'n' Roll seen as the grooviest shit in the 50s when it's just averagely groovy (ie. unremarkable)? 3 days ago:
It is still remarkable. You need to understand that looking at things in perspective and in big picture is very important. (For many other tings also).
Try to listen to top hits from the 1920s, 30s, 40s and so on… And you will see the shift, the magic that Rock was. Are those rock songs meh - compared to later songs? Definitely. But those masterpieces would not have existed if those meh songs were not introduced - and for those who fought to keep them socially tolerated and later accepted. - Comment on [deleted] 4 days ago:

Second this. If this post is not a troll one - then thus post screaming for help.
Too many things, imaginary smells, social pressure of jokes and disassociation of “I’m not like the other girls”.
You can be girl or boy or whatever in between, or none of those - but you are no more special than all the humans around you. Not one bit.
Therapy, education and meditation needed. - Comment on What's the best free version of word? 3 weeks ago:

I believe it is going to be a huge deal as the gamers are aging out. (And if you play on a Tv).
Give me a freaking texts size option! And not just size 6 to size 8! Big effin text!
It is a huge pet peeve of mine. - Comment on Do people actually believe those "gurus" on the internet that supposedly "give advice"? These seems very sussy and feel scam-adjacent, isn't it? 5 weeks ago:
If you want to see how hard people want to believe they read on the internet… Watch some cop bodycam videos with sovereign citizens ‘traveling’
- Comment on Are we truely prisoners of our upbringing? 1 month ago:
I believe it depends on the severity of the trauma. And of course our mental strength and if we are on the spectrum or not, have any abnormalities and so on… So many components.
If you had a single Mom and you only met your dad every weekend that could affect you.
If you were starved, beaten sold into sexual servitude and then failed by the legal system… I don’t think you can get over that.
But the first step is to understand how messed up it was and you didn’t deserve it. No child deserves any trauma. - Comment on YSK about Psyllium husk 1 month ago:
Hmm, sounds great! Then it should work with hazelnut spread also. I’m still partial to Nutella > PBJ. But any fiber is good fiber! :)

I do recommend chia seeds soked overnight also. For better “turning to shit” power you can use a coffe grinder before soaking.
Great topping for cereals. - Comment on What free to play games can run smoothly on my old laptop? 1 month ago:
Not smooth but Guild Wars 2 can run on those specs, obviously on very low settings.
Path of Exile should work also. These specs af not that bad. Most 10+ year old games should run easily. I would just check steam for older F2P games, there are a lot more. I think swtor and eso should run also. Those had F2P tiers. - Comment on Where do you post a meme if its only half-political? c/memes or c/political memes? 2 months ago:

Again llm is a misused tool. They do not need llm they need psychological help.
The problem is that they go and use these flawed tools that were not designed to handle these kind of use cases. Shoulda been? Maybe. But it is not the AIs fault that we are failing to be a society.
You can’t blame the bridges because some people jumped off them. They serve a different reason.
We are failing those people and forcing them to tirn to llms.
We are the reason they are desperate - llm didn’t break up with them or make them loose their homes or became isolated from other humans.
It is the humans fault and if we can’t recognize that - we might as well end it for all. - Comment on LLMDeathCount.com 2 months ago:
I believe it is not the chatbots falut. They are just the symptoms of a broken system. And while we can harp on the unethically sourced materials they trained them on, LLM at the end of the day is only a tool.
These people turned to a tool (that they do not understand) - instead of human connection. Instead of talking to real people or professional help. And That is the real tragedy - not an arbitrary technology.
We need a strong social network, where people actually care and help each other. You know all the idealistic things that capitalism and social media is “destroying”.
Blaming AI is just a smoke screen. Or a red cape to taunt the bull before it gets stabbed to death.

In that case I’m editing it. I’m sorry for my mistake, I thought it would be useful to a point. That’s why I said it was AI.

I asked chatgtp to explain the paper - here is what it said - so you don’t have to:
Many computing tasks (especially in things like signal processing, wireless communications, scientific computing, and AI) boil down to solving equations like A x = b (a matrix times a vector equals another vector). Nature +1
Traditionally these are solved in digital computers (with floating-point arithmetic) and for large problems this can be slow and energy-intensive. Nature +1
An alternative is analogue computing where you do operations more directly in hardware (for example using resistive memory devices) rather than converting everything to the digital domain. These can potentially be much faster and more energy-efficient. Nature +1
But analogue computing has historically had a big problem: precision (how accurate the answers are) and scalability (how large a problem you can handle). This paper addresses those issues.
What they did
They used resistive random-access memory (RRAM) chips — specifically memory devices where each cell’s conductance (i.e., how easily it lets current through) acts like a number in a matrix. Nature +1
They built an analogue system that does two key steps:
A low-precision analogue matrix inversion (LP-INV) step.
A high-precision analogue matrix-vector multiplication (HP-MVM) step, using bit-slicing (splitting the number into parts) to boost precision. Nature +1
They also developed a method called “BlockAMC” (Block Analog Matrix Computing) — this partitions a large matrix into blocks so that the analogue method can be scaled to larger sizes. Nature
They built the hardware: RRAM chips in a foundry (40-nm CMOS process) with a 1 transistor-1 resistor (1T1R) configuration, supporting 3-bit multilevel conductance (so eight states). Nature
They experimentally solved a 16×16 real‐valued matrix inversion with ~24-bit fixed-point precision (which is comparable to 32-bit floating point) using their analogue system. Nature
They also demonstrated a real‐world application: detection in a “massive MIMO” wireless-communication system (16×4 and 128×8 antenna setups) using high-order modulation (256-QAM). Their analogue solver matched the performance of a digital processor in two/three cycles. Nature
They measured the speed (the analogue inversion circuit converged in ~120 ns for 4×4) and estimated that their approach could offer ~1000× higher throughput and ~100× better energy efficiency than state-of-the-art digital processors for the same precision. Nature
Why it matters
If you can solve matrix equations much faster and with much less energy, that opens up possibilities for e.g. base stations in wireless networks (where there are many antennas), real-time signal processing, AI training, scientific simulation, etc.
Using analogue hardware like RRAM arrays helps overcome the “von Neumann bottleneck” (the slowdown/energy cost caused by moving data between memory and processor) because the memory is the compute. Nature
The fact that they reached high precision (comparable to digital float32) is important because one of the big criticisms of analogue computing has been that it’s too “noisy/low precision” for serious tasks. This shows you can do it.
The scalability (through their BlockAMC approach) means this isn’t just a toy demonstration of a 2×2; they show up to 16×16 and hint at larger.
Important caveats & challenges
Their currently demonstrated arrays for LP-INV are small (8×8) and scaling to much larger arrays still has engineering challenges (device reliability, wiring resistance, noise, etc.). Nature
The BlockAMC algorithm introduces some overhead when you scale up. The complexity isn’t strictly constant for arbitrary large matrix sizes; there is some cost. Nature
While they show big energy/throughput gains in estimates, real‐world integration (with all peripheries: DACs, ADCs, control logic) will still need refinement.
Applications: They show wireless signal detection (MIMO) which is great, but other domains (scientific computing, general AI) may have different requirements (matrix size, sparsity, conditioning).
The analogue computing world still has to deal with variability, drift, calibration, faults in memory cells, etc. The paper mentions some of these (e.g., stuck-at faults) and how to mitigate them. Nature
In everyday terms
Imagine you have a huge table of numbers (a matrix) and you need to solve for a vector x so that when the matrix multiplies x you get some result b. This is like solving a system of linear equations. Normally, a computer does this step‐by‐step in digital form and it takes time and energy (especially for large tables). What these researchers did is build a physical piece of hardware where the table of numbers is literally encoded in a memory chip (via conductances) and the solving is done via analogue electrical flows. Because electricity flows in parallel and instantly (relative to digital clocked logic), it can be much faster and more efficient. They also built in ways to ensure the answers are very accurate (not just approximate) and to scale up the method to realistic sizes. In short: they brought back some of the old “analogue computing” idea, but using modern memory chips, and showed it can match digital precision while running faster / lower-power.
- Comment on Historians never talk about the "good old days". 3 months ago:
It’s because they’re way more aware of the drawbacks of certain eras.
Slavery, racism, inequality, lack of resources, lack of education, lack of clean water, how many of your children will make it to adulthood, famine, floods, lack of roads…
Every “good old day” was worse in some aspects. - Comment on Automattic CEO calls Tumblr his 'biggest failure' so far 3 months ago:
Ahh that makes kinda sense!
Tho I’m not interested much in porn - I am very pissed about credit card companies deciding for the users of what they can purchase or not. I believe crypto will help a lot with these overreaches in the future. - Comment on Automattic CEO calls Tumblr his 'biggest failure' so far 3 months ago:

That’s also true :)

Obviously not every job is open to people who show up, but if you just want any job - any small (mon and pop) store will be impressed.
Honestly I saw some job applications that peope would not believe… - Comment on Why do so many boomers and even some gen x believe so peristently that if you dressup and show up in person anywhere you will get whatever you went there for? 3 months ago:
The respect is the key word. Nowadays most people don’t give a shit. So when you do, you stand out. And if you treat someone with courtesy they will be much more favorably towards you.

I believe that asking respectfully won’t hurt. And if you are lucky you can get ahead of people who do not show up.

It’s highly depends on a situation. But generally speaking it does work in a lot of situations.
You want work? Clean up, print a dozen resumes - apply online (if they have a website), then go and show up in the physical location. You will be noticed waaay more than a silent application.
You want to solve a service issue: even with big probiders atnt, T-Mobile there is a chance that a corporate store manager can do something.
Sometimes even between offices it can help if you show up in addition to the regular channels.
Being proactive, clean and respectful can take you long way.
