Speaking of mechanical devices to selectively obstruct radiation ...

I had a manager who is a clever fellow. He used some construction toy with electrical motor abilities to rig together a test apparatus whereby a mobile device was placed into a steel cooking skillet, and the apparatus was periodically lifting the lid.

This caused the device to go into and out of mobile coverage, allowing for testing of in-and-out-of-coverage transitions, and reproducing problems reported with respect to them.

It is definitely not for handling nuclear weapons-related information only. It's as generic as a normal TS in that agency and is even given temporarily to people coming in from outside agencies with a TS/Poly for meetings.
> You're not really a regular bicycle anymore due to your speed

I don't understand, ebikes are regulated and the assistance will top at 25kmh in most EU countries, which is a very average speed for a bike without assistance.

Unless you're talking about speed bikes, that can ride faster but are regulated like a motorcycle with license plate and can't ride on cycle paths. So it's just an electric motorcycle that looks like a bicycle.

I recall the two biggest stories about foreign spies in these labs:

1. Chinese blamed for stealing Los Alamos secret by stashing hard drives behind a copy machine and grabbing them later.

2. Chinese engineer at JPL worked there for decades and was thought to be a nice family in Pasadina - but lived in a really super spartan house and the wife was the engineer's handler and their kids were the mules to haul data back to ccp

3. China's trickle hack on Lockheed by phishing employees who had attended defense conferences

4. China hacking Lockheed providers in Taiwan with an air gap and sneaker-net to gain access to Lockheed laptops via USB exploits (this was one of the factors, IIRC why epoxy in USB ports was common) -- ((But if you ever had any SGI O2 machines -- there was an additional port (serial I think - I don't think they were USB) but this 'option' was several thousand more $ -- but it was on every machine and all you had to do was punch out the plastic cover from the case)

5. Israel + USA hacking Iran via STUXNET in the same method with air-gaps etc.

6. The guy who worked at oak ridge, took on a Russian Mail Order Bride and got her a job in oak ridge (accounting I think, I can't recall) -- and it turned out she was a Russian handler, but they denied it -- but everyone knew that every single person from the USG who went to Russia was assigned a female handler, and these handlers were highly trained, and they had several levels of handlers above them to ensure non-defection chain-of-custody-of-intel.

It's true that the very existence of Google has motivated people to make limitless amounts of spam content that could get found in Google.

For your second point what I know is that there has been 4 decades of research into search relevance ranking and about 0% of that knowledge has made it into real life products.

I went through a phase where I interviewed people at 15 or so search vendors (e.g. Open Text) and not one of them told me that they or their customers thought relevance was a priority. One of them participated in the TREC competition because they thought it would give them some credibility but then they decided it didn't.

If you look at any of those products you find they have hundreds of low-quality "integrations" with various data sources because they believe that's what sells the product.

In the 80's I was intrigued by literate programming. I studied Knuth's literate source code for TeX carefully.

You're right, it never caught on, but a few years ago I read a statement by Knuth that said he still writes code that way.
Today, about half of the time my Emacs configuration is written in org-mode babel[1] which supports literate programming. In fact, this a common example of literate programming that I see on the internet along with Jupyter Python[2] notebooks widely used by scientists.

Although literate programming seems to work okay for Emacs configurations (often reaching over a thousand lines of code), I've never felt like the approach helped me enough to employ in other programs.

Google is the best and spends billions keeping the spam bots at bay. Lots of people claim it's worse than before. Don't trust them, they are idiots.

Google doesn't index a few things. Scihub for instance.

They also don't return results outside your language. This is a huge part of the internet they keep in walled gardens.

Picture and video search is limited. And they have not continued with the facial recognition in their search.

You could also improve on their filters.

A few of these things you'd spend billions on to do from scratch, then Google would add.

I'd suggest looking to the history of science fiction, which ... goes back further than you might expect:

https://en.wikipedia.org/wiki/History_of_science_fiction

For a modern view based on a relistic sense of rocketry, science, and technology, I'd probably start with the early 20th century. There were several popular works written by the 1930s, and I'd expect some from earlier.

Wikipedia's Space Colonization article suggests the work of Konstantin Tsiolkovsky, which I was also going to suggest, beginning around 1900.

https://en.wikipedia.org/wiki/Space_colonization

https://en.wikipedia.org/wiki/Konstantin_Tsiolkovsky

I'm not aware of specific illustrations accompanying these, but any such would all but certainly follow those dates.

The same article also suggests:

In the 1920s John Desmond Bernal, Hermann Oberth, Guido von Pirquet and Herman Noordung further developed the idea. Wernher von Braun contributed his ideas in a 1952 Colliers article. In the 1950s and 1960s, Dandridge M. Cole[18] published his ideas.

The Werner "who cares where they come donw") von Braun article was part of a series "Man Will Conquer Space Soon!'

https://en.wikipedia.org/wiki/Man_Will_Conquer_Space_Soon!

The series was reprinted in 2016:

One better be able to read old code. For example the first lines of the SBCL Lisp implementation were written around 1980, when it was called Spice Lisp. The version from 1984 looks readable: http://www.softwarepreservation.org/projects/LISP/cmu/Spice_...

This is why war in the pacific is a disturbingly realistic possibility. There's no plausible scenario under which such a war is existential for either side and so no plausible path to nuclear escalation. But this could lead to a very protracted conventional war we haven't seen in a long time.

IMO it would make more sense to just treat assignments as expressions, as is done in C-like languages. Maybe I'm just more accustomed to C-like languages, though.

I think that one thing that makes the statement confusing is that the first equals sign serves a purpose completely different from the second equals sign, but both of them are represented by the same character.
I am generally against worker protection for things that are voluntarily agreed on.

The problem is that bosses can sneakily introduce things that weren't agreed on, and this is usually bad for the worker because the worker has less power in the relationship, there are frictions to switching jobs, they have leverage over your reputation, and resolving the dispute via government or the courts is impractical and expensive.

This can be thought of as a type of mild fraud, where two parties came to a contractual agreement that one party then violated (or perhaps it's a grey area that wasn't explicitly covered contractually).

This is why everyone should be in favor of some basic level of worker protection. Even if you're a hard libertarian - as they are purportedly against fraud, too.
I can only guess that it's a mix of the drive towards ending the 'pandemic situation' (see germany for example) and the easy brownee-points some politicians see in going with the train of 'I value lives over (money|...)

I will give an app negative reviews for this practice.
Search engines have been coming up lately, so maybe this is a good a place as any to discuss some back of the envelope calculations.

Let's say we wanted to recreate the web index made by Google. How much cost and engineering would it take?

Estimating the size of the web from worldwidewebsize.com [0], this is estimated at around 50 billion (5010^9). The average web page size looks to be on the order of 1.5 Mb (1.510^6). The nominal cost of hard disk space is about $0.02 / Gb [2].

So, roughly, that's 75 exabytes of data (~7510^15). At a cost of $0.02 / Gb that gives roughly $1.5M just to buy the hardware to store (a significant fraction of?) the web. The Hutter prize exists [3], so maybe there's some confidence that we only need to actually store 1/10 of that, so around $150k in costs.

For perspective, that's 10 multi millionaire silicon valley types donating about $150k each, 100 "engineer types" at $15k each or 1000 to 10,000 pro-active citizens at $1.5k to $150 each (just* for the hard disk space, discounting energy, bandwidth and other operating costs).

If we try to extrapolate lowering hard disk space costs and take the price halving to be about 2.5 years with a current (pessimistic?) cost of $0.02/Gb, that's about 10-15 years before a petabyte scale hard drive is available to the consumer for $1000.

From my perspective, I would ask "why hasn't a decentralized search index been created and/or is in wide use?". My guess is that figuring out a robust enough system that's cheap enough is still out of reach. $150 might not seem like a lot, but you have to convince 10k people to devote energy just to search.

Put another way, when does the landscape change enough so that decentralized search is a viable option? My guess is that when people can store a significant fraction of the web locally for nominal cost is the determining factor. Maybe some great compression and/or AI sentiment analysis can be done to bootstrap and maybe some type of financial incentives can help solve this issue, but my bet these will only provide a light push in the right direction and the needed technology is the underlying cheap disk space.

As a side note, the worldwidewebsize.com [0] shows the number of indexed pages by Google holding pretty constant over a five year period with a sharp decline somewhere in 2020. I wonder if this is the method of estimation or if Google has changed something significant in their back end to alter their search engine and storage.

> Which to me implies the Vulkan API is so simple, and close to metal, that it doesn't differ between implementations

As someone with 20 years 3D programming experience including paid work in DirectX and OpenGL ES 2.0, I attempted vulkantutorial.com but gave up because it is too hard. It really is 1000 lines of C/C++ to even get a flat shaded triangle on screen. Vulkan has validation layers to help with writing conformant portable code, but the validation layers are written by your GPU manufacturer and so you can get things that pass on an Intel GPU but fail on nVidia. If you've ever tried porting your "portable" ISO C++ code that works with GCC over to Visual C++ and dealt with 1000s of lines of compiler errors it's kinda the same thing. Vulkan has shaders that precompile to "portable" bytecode but I also noticed that the time delay of loading these "precompiled" bytecode shaders was instant on one Intel GPU but took about 5 seconds on an nVidia GPU. The nVidia driver then cached the results (I know not where) so that subsequent runs were faster, but the cache can be invalidated by either a driver update or a shader update, so your game level loader will need an "ifShaderLoadingSlowerThanMolasses() {...}" code path to deal with your users experiencing slow load times after a video card driver update, etc.

Summary: in ages past it was possible for mere mortals to write visualizations and simple games directly in OpenGL/DirectX, but with Vulkan most of us will need a middleware layer on top of it to get anything done within a deadline. If you want an open source portable solution I instead recommend Godot. If you want to make a 3D game that makes millions of dollars with less than 3 years of development and can deploy to Nintendos and Playstations with a button click I recommend Unreal Engine or Unity.
I'm saying people are building sputterers, waterjets and even fabing transistors and ICs(Sam Zeloof) in their garages. It goes way beyond factoids. You can connect with experts in just about any field.
I've also tried to learn SDL and had trouble in the past. Recently however I've been working with openbsd and it also doesnt really have a tutorial but i've found myslef productive by virtue of good docs that I know are there, and I think SDL has the same type of thing, where it takes a bit more effort to understand that a tutorial can feed you but once you understand it and how to read its documentation you can really get very proficient with how it and it sub-libraries work.
>> Just because one has a Q clearance does not mean you are provided any classified information.

Exactly.

"Need to know basis." is the key phrase here.

The clearance is just the tag that gets you in the door. If you do not have a specific need to access the information to do your specific job, you do not have any right to access it.

AFAIK, deliberately taking steps to access info beyond your need to know -- even if it is within your clearance level -- is grounds for disciplinary action or prosecution.

So the TS/Q-cleared janitor, parts contractor, or engineer from the other project who gets found browsing in TS/Q file cabinet is waaay out of line,and likely in big trouble.
Maybe there's nothing wrong with this submission and maybe I'm a skeptic but definitely seems like a gamed submission. Submission by a new account, another new account posts that this is the best piece they've read about this game, front page in less than 30min...

Also the title seems eerily similar to a good primer on the company that I had read earlier this year by twitter.com/packym that was titled, "Infinite Revenue, Infinite Possibilities." That was a super bullish piece though so perhaps the growth is tapering off as the title of this piece seems to suggest.

Anyways - I'd highly recommend that piece [0] for a primer on the company and catalysts for its growth (if anyone reading this isn't familiar with this company and wants a deeper dive + more context around blockchains+games).

Ask HN: How to build my relationship with the internet like it was in the 90s
Hey, long time reader, first time writer. I just created this account!

I'm in my early 20s, CS student, and i grew up with social media: Myspace, HI5, Facebook,Reddit, etc, with algorithms controlling my content consumption and maintaining my addiction. In fact over the last 6 months i tried to quit Facebook at least three times and today i started my fourth attempt. The more i read how the internet was in the 90s/early 00s the more i long something i never experienced which is weird (the same thing i feel about punks and 80s dark wave but that's another matter). I miss blogs/personal sites. i miss quality information sharing in the form for articles and not "7 ways to/10 things to/You wont fing believe it do it now. I miss the hacker fun culture: Pwning for learning and fun, and also not for too much mayhem etc.

Few weeks ago, i think, i found a post on HN about the "search.marginalia.nu" and i love it. Obviously it has a long way to go but it's something i desperately needed.

I want my relationship with the internet to be driven by curiosity for knowledge and learning and not by content consumption and addiction.

I'm tired with the way today's internet works.

Literally, the only reason i haven't deleted my Facebook account already is because of the events tab. The only useful feature of that platform for me. Sadly everyone moved to Facebook and any short notice gathering is being posted there.

It's very much less convenient than a bicycle since it's bigger, less maneuverable, harder to get in/out and harder to "park".

Also, when commuting you don't need "fast". A bicycle or a regulated ebike are sufficient enough given the constraints you will encounter (lights, stops...).
What makes using (e)bike to commute awesome is not the speed per se, it's the reliability. You won't be stuck (= taking part) in traffic, so if on Monday you take 30 minutes to go to work, it will be the same each day of the week. No need to rush to +30kmh between lights.
Yeah I read that, but it's not going to be good for that. For one thing that isn't going to work in a nuclear reactor core because the neutron background is orders of magnitude higher than any neutron generator could hope to produce. For the other uses they mentioned... I mean like I said there's no reason it wouldn't work (over short ranges) but there are simpler solutions that don't involve [very dangerous] neutron radiation. Plus a neutron generator requires a decent bit of power to run (they're basically a compact particle accelerator) so you're back to needing a vessel penetration. And the idea that such a device would be useful for emergency rescue operations is frankly silly.
Neat! I didn't know, thank you!

What continues to confuse me about this game is what is the source of money into the ecosystem? If the vast majority of players are doing this for the income, who is the buyer? Are there a small number of 'whale' players who are effectively paying small armies of (by all accounts) filipinos to 'farm' the game for them? Is there some kind of money laundering angle here?
$2,000 per month for this drivel is absolutely hilarious. Normally I’m not a big fan of outlandishly overinflated egos peddling nonsense for cash, but the sheer arrogance on display here is actually somehow impressive.

That being said, the subject matter here is so incredibly stupid that I have no option other than to hope that it fails magnificently (along with the ‘games’ it tracks).
“We have incorporated their diversity into our own. We are Borg.”
Probably not, actually. Why? They are not developers, they're artists. They will learn and use the tools available to them. If even a fraction of the effort that developers put into improving their own tools actually went into improving others', then we wouldn't be stuck with such terrible software out here in the real world. But I understood why it is more rewarding and engaging to focus inwards.
It's very easy to convert a hook to a HoC, purely wrapping that functionality in a class component.
