I'm working on a different type of compression (for all file types). I am able to to get in the 10-20% range, but the speed to compress is to slow many times, or the compression doesnt complete at other times (I've been working on this for years). My personal website: http://danclark.org

Well, it doesn't really show something travelling faster than light, any more than if you shot a laser at the moon and looked at the speed of the dot on the surface as you moved it through some angle. The dot can move arbitrarily fast, but nothing in the system is actually moving faster than light.

In the long run, you should just keep adding talents. So yes, you may end up adding a couple of 'duds', but you'd surprised how many of these initial duds turn out to have substantial value in the long run.
Yeah I find it a bit ironic that people complain that "rich" people aren't trying to sell their own story and instead think about how to help a non rich mortal. Of course it is a bit hypocritical because they may not know much about the middle class or below but the point is that they are trying instead of assuming that you just walk down the golden path you were born into.
Not sure why i’m getting downvoted. When I come back to a project 6 months after I last touched I might as well have never heard of it for all I remember.
Don't have anything to add right now but I like the idea of this thread and would support it becoming a regular thing.
A way to preserve and link factual data sets.

Most reference to Wikipedia are dead links.

Many legacy media will stealth edit articles or
outright delete them.

Original media files can be loss and after strange eons their authenticity will not be able to be asserted.

It will soon be impossible to distinguish from deep fakes and actual original and genuine media.

Some regimes such as Maoist China wanted to rewrite their past from scratch and erased all historical artifacts from their territory.

There are strong pressure to create an Orwellian Doublespeak to erase certain words entirely from speech, books and records. With e-books now the norm it has now become legitimate question to ask if the books are the same they were when the author published them.

Collaborative content websites have shown that they were not immune to subversive large and organized influence operations.

I have set my mind to multiple solutions (even bought a catchy sounding *.org domain name!).
Obviously it will have to be distributed as to build a consensus and thus it will have to rely on hashes. But hashes alone are meaningless so some from of information will have to come along with them, which in themselves are information to authenticate with other hashes. I was thinking that the authentication value would come from individual recognized signatories. Those would be a a mesh of statements of records. For example you might not trust your government, but you might trust you grandparents and you old neighbors who all agree that there was a statue on the corner of the street and they all link to each other and maybe link to hashes of pictures and 3D scans with links. Future generations can then confirm those links with other functional URIs.

Something like blockchain technology seems an obvious choice but I have no experience with that (for now) but also there is the problem that it needs to be easily usable; therefore there is a need of a bit of a centralization (catchy domain name yay!) although any one could setup his/her own service for certain specialized subjects.

Thoughts?
This is on our list of possibilities. It would take a little more time than I'd like to spend on this problem but it would work.

Heating flash media can repair the oxide layer, depending upon temperature and duration.

In 2012, research on short bursts of 800°C heat could vastly extend media lifetime. Supposedly 250° for several hours has the same effect (assuming the packaging can withstand it).

In view of the shortages of recent years, we should mandate some form of this technology so we don't waste foundary output on throw-away parts (planned obsolescence).

Sure, but I guess I'm wondering if that is just a convenient effect of the centering, or if it is actually necessary to prevent the wheels from skipping.
Thanks, I hadn't heard of that and I will look into it. This is a research setting with plenty of hardware we can request and not a huge number of users so that part doesn't worry me.
Well, it was unkilled briefly and then rekilled. There is exactly one meaningful comment critiquing the fact that the models are purple and therefore don't look realistic, which sounds like good feedback if they wish to improve on what they are doing.

Maybe someday the sexually sane people will get the upper hand and sexual education will be less drama than it seems to be today.
Usually, I do this sort of thing somewhat manually, building up an algorithm (mostly classical, with a little ML as a treat) that can deal with the problem.

I'd start by detecting common typos. Typos are similar to un-typo'd data, so I'd do a frequency analysis on the textual representations of manufacturer name and model name, and a Levenshtein distance calculation, then synonymise the obvious synonyms (looking things up when I wasn't sure). The key idea is that you have access to more information than just this dataset: Tony and Tomy are different manufacturers, but Sony and Somy aren't (even though somy is in the dictionary and tomy isn't).

Once the manufacturer and model fields are mostly typo-free (after typo replacement – don't modify the original file, if you can help it!), you can start looking at dimensions and colour. Sort by manufacturer, and start de-duping entries. Once you get a feel for the process you're doing (e.g. under what circumstances do you check whether there's a 102mm Phillips screwthread?), you can start automating bits of it. There will always be special-cases, but your job is to get the data processed correctly, not to get the computer to process the data.

Accidentally aliasing two different products is much worse than leaving the same product described twice, so err on the side of “these are different”. (Keep in mind that manufacturers of some things, e.g. SD cards, often pretend two different products are the same – so you can't always win!) Remember, humans exist: bothering them a few million times is a problem, but bothering them a few hundred would be okay.

When new data comes in, I'd run all the code I used to come up with my system, and see if the output was notably different. If it was, I'd get the computer to let me know.

I'd also add some way for users to flag duplicates. Many humans make light work.
In your example, I would say that it's addition that's failing.

Addition is defined as an operation with two inputs. You can't add more than two things, unless there is some particular rule that lets you.

If you have finitely many things, then this rule is the associative law: add them pairwise in whatever order, and you are guaranteed to get the same result.

To add infinitely many numbers, you need to talk about limits. Formally, when you say something like

1 - 1/2 + 1/4 - 1/8 + 1/16 - ...

you mean: look at the sum of the first two; then, look at the sum of the first three; then, look at the sum of the first four; and so on -- this sum converges to a limit, which is 2/3.

This sum is "absolutely convergent", which means you get the same result no matter how you order the summands, but some infinite sums change if you reorder things!

With points on the sphere the situation gets even worse, as there is no way to "list them in order". These sets are "uncountable", which means don't even try to sum any function defined on them.

To say approximately the same thing using technical jargon, one has countable additivity for Lebesgue measure on the reals, but uncountable additivity does not hold.

That strikes me as eminently unsurprising personally. By definition if you fail then you weren't making enough revenue to sustain it. There are two nasty pitfalls which I have heard often snaring them - either paying for tools and other assets when they lack demand or failing when demand saturated due to being unable to scale up correctly.

Revenue and profit are conflated but are not the same thing.

A full CPU is useful for decision intensive or time series intensive data. Normal ML inference is not necessarily either of those. You could have more complicated neurons (or just make normal compute tiles which they may be doing).
Toy trains not having this feature is a wasted opportunity.

In response to your numbered items:

1) Los Alamos/the Manhattan Project is explicitly claimed to be what the average person thinks Feynman was all about, what his primary contributions were.

"Show a video of Richard Feynman, and many will recognize him; ask for some of his essential contributions, and few will know how to respond, beyond his participation in the Manhattan Project during the Second World War, which developed the atomic bomb"

Then:

"In fact, his collaboration in the nuclear program was the most material of his contributions."

I was pointedly dismissing that.

2) Yes, I agree! This is my point. People think he was a major figure though.

3) Yes, I agree! This, again, is my point.

He described stuff so vividly, from the top scientists, to the Trinity test, to the feelings of despair after the bomb was used, that despite the fact he wrote about playing games with the censors and the locks, it's easy for people to slide past it and think of him as one of the major scientists. As evidenced by this article saying that they do.
Again, just a promise.
I'm not being absolutist. Eat your meat now and then. But if you're interested in longevity, cardiovascular disease is the #1 cause of death. So, I personally make diet decisions with that in mind.

There are a lot of bunk studies, but that doesn't mean you should ignore all scientific studies altogether. If you have multiple randomized controlled trials with good sample sizes saying certain things, and funded by public health institutions, I want to pay attention to those.

You're right about the agricultural industry and its influence. The beef, chicken, and dairy industries are chief among them.
I bet HR prepared the legal language to avoid discrimination charges. Even if the immigration status is legal, Americans have an unfair advantage just because they were born in the right place. Americans live in a privileged bubble, especially the tech sector.

Remember tech wanted to increase the quota for H1Bs? It was a pro-immigration marketing stunt - because it is cheaper for them to abuse more workers.

Progressives/liberals fight for minorities' rights, but who cares about immigrants, even if they are the backbone of your economy? Tech doesn't care, they profit from it. Tech (indeed, American enterprise) has always been a marketing show for the rich.

My experience with bigger systems is that when you have 100 developers passing references around it becomes hard to manage who is responsible for deallocation of an object. This leads to dangling pointers and debugging. Going to languages with automatic memory management made such projects a lot more reliable.
Can someone explain the flaw in my reasoning here?

Assume I have a sphere made of pure iron. I divide the sphere into individual iron atoms. I divide this group of atoms into two groups of atoms. I take each of those groups of atoms and form them into 2 spheres. How is it that these two new spheres are not either less dense or smaller that the original sphere?

I really appreciate your push for learning environments that don't constrain students and students can just be who they are. In other words, what are the absolutely minimum number of things that we insist on as rules, so that students feel the freedom to take ownership over the rest.

This all seems like over-complicated BS. The how's and why's of how you arrived at a situation shouldn't be used to make a decision NOW. Chose the path going forward that maximizes gain, or minimizes loss relative to the present. Doing otherwise is the sunk cost fallacy. If you choose to include your psychology, emotions, or social appearances into that calculation, so be it, that's your value-scale, but accept that's what you're doing.

I have my doubts about the snap style of visual programming, e.g. due it emphasizing imperative code too much, but I have no doubt that text is bad. I've watched too many students struggle with text and the beginning, and this accident complexity slows down the learning by weeks.

I didn't remember quite correctly - here it is, from the section "A Different Box of Tools" in "Surely you're joking Mr Feynman". He doesn't state it explicitly, but I think it's clear they must have been talking about Banach-Tarski:

...It often went like this: They would explain to me, "You've got an orange, OK? Now you cut the orange into a finite number of pieces, put it back together, and it's as big as the sun. True or false?"

"No holes?"

"No holes."

"Impossible! There ain't no such thing."

"Ha! We got him! Everybody gather around! It's So-and-so's theorem of immeasurable measure!"

Just when they think they've got me, I remind them, "But you said an orange! You can't cut the orange peel any thinner than the atoms."

"But we have the condition of continuity: We can keep on cutting!"

"No, you said an orange, so I assumed that you meant a real orange."
Have been using openai codex for a week and it's shockingly good at SQL with well defined prompts.
The sunk cost fallacy fallacy: we have perfect knowledge, particularly of domains we haven't poured a lot of time into, and therefore can, with certainty, act perfectly rational at all times.
I have been developing software that includes SQL for twenty years, and watched my own mental progress from misunderstanding to understanding. I found the biggest initial problem is that I used to imagine SQL queries as an imperative language rather than as expressions of data. Maybe in the teaching of SQL, this should be highlighted so absolute beginners can have that mental model when they are formulating solutions and grappling with the syntax.
We just assume that masks work and therefore leaving a control group unmasked is unethical. It is the same with the vaccines. The trials have technically not finished yet, but the control groups have long been vaccinated. The real control groups now are the much maligned vaccine hesitant.

If you don’t care about cost of ownership, use CUDA. It only runs on nVidia GPUs, but the API is nice. I like it better than vendor-agnostic equivalents like DirectCompute, OpenCL, or Vulkan Compute.
I know other horribly screeching trains, e.g. the Paris metro.

Even if you can use it to send text messages, that’s a huge win and a giant selling point.
Roughly speaking, you just need a mobile receiving unit, or multiple fixed receiving units, with a reorientable directional antenna. You find the heading where the signal has maximum strength from a few points, and then triangulate.

I know this isn't going to sound as sexy as AlphaGo for plants, but I really think this is a classic multilinear optimization problem once you've properly labeled the data and defined the dynamics between the plants / other organisms (e.g., aquaponics). You're looking to optimize multiple variables across a set of known constraints and I think if you properly defined these constraints you could save a lot of headache / buildout by leveraging a pre-exsting toolset like Excel with the Excel Solver add-in an a couple hundred user defined functions. We're talking 1% of the work to get something useable and product-market-fitable with automatic output of graphs, etc, that clients could tune and play with locally without you needing to actually share the source sauce. Eventually you could switch to Python for something more dynamic / web based.
