So a weird thing about ultraviolet light, like blacklights and UV-C disinfecting light, is that it's invisible. Kinda. And also Kinda.

See there's a distinctive look to blacklights, they look like this.

But it turns out this isn't the ultraviolet that you're seeing.
See, the light produced by the bulb isn't perfectly monochromatic UV. Blacklights are in the UV-A range, which is 315 - 400 nm. The human vision range is 380-nm to 700nm.

There's a little overlap there, between the high UVA and the low end of human vision...
And there's multiple types of ultraviolet lights, but the kinds used in blacklights peak at 370nm or 340nm

so while most of the light coming out of the bulb is in the invisible UV range, some of the light is a bit higher up in the spectrum, which makes it slightly into the visible violet range.

So the light you see from UV lights is either the not-UV light it produces as a side effect, or something else fluorescing.

@RubinReport Your commentary on the dangers of silicon valley coming under the spell of wokeness and cancel culture is spot on. I know this to be true because in Bitcoin we have already lived through a similar culture war against crypto anarchists.

We experienced firsthand the tactics such groups use to eliminate ¨wrongspreak¨ from public debate. And as you rightly recognize, this exact thing is currently happening in society as a whole. And not surprisingly often by the exact same people.

For example, Jack Dorsey, investor in and honored by the BTC cult, is the same person responsible for the twitter bans of many people, including a lifelong ban for the former president of USA. BTC ideology and such policies may seem incompatible with each other, but it is not.

As we stood up against social engineering and the destruction of language in Bitcoin we have been demonitized and deplatformed. Evidence: Just read the whitepaper and see how BTC, what they tell you is Bitcoin, doesn´t even come close to it.

So, just like you, we have been busy building our own alternative platforms based on new incentive structures and the Own Your Data philosophy.

For example have a look at this excellent presentation on @twetchapp

Hmm... something interesting I learned from my buddy @RomeenSheth about McKinsey.

I thought they are just a stale boring consulting co

But he told me they've acquired a ton of software co's & now have a $100M ARR tech portfolio now (!)

I'll let him explain - guest thread!

If you don’t know, McKinsey is a gigantic consulting company:

- $10B+ in revenue
- 80%+ of the F500 as clients
- Hard to get a job there. (<1% of applicants get hired)

Their bread and butter (70% of revenue) used to be “pure strategy” work. That’s now down to just 10% - why?

Clients are demanding “value based” billing. Meaning less "guys in suits talking" and more "show me something tangible"

For example -lets say a client hires McKinsey because they think they are spending too much money on procurement.

So McKinsey acquired Orpheus - a software co that does analytics for procurement.

Instead of advice, they give them a tool (a real solution)

Now Orpheus has been around for 15 years. McKinsey can buy it at a fair price, knowing that it can inject steroids into the business.

Why?

The lesson here is not "OMG big tech is more powerful than the president, this isn't how it's supposed to be!" but "Even the president is not exempt from the rules we all agreed to follow, that is exactly how it's supposed to be."

0/ I’m tired of hearing about observability replacing monitoring. It’s not going to, and that’s because it shouldn’t.

Observability will not _replace_ monitoring, it will _augment_ monitoring.

Here’s a thread about observability, and how monitoring can evolve to fit in: 👇

1/ Let’s start with the diagram (above) illustrating the anatomy of observability. There are three layers:

I. (Open)Telemetry: acquire high-quality data with minimal effort
II. Storage: “Stats over time” and “Transactions over time”
III. Benefits: *solve actual problems*

2/ The direction for “Telemetry” is simple: @opentelemetry.

(This is the (only) place where the so-called "three pillars” come in, by the way. If you think you’ve solved the observability problem by collecting traces, metrics, and logs, you’re about to be disappointed. :-/ )

3/ The answer for “Storage” depends on your workload, but we’ve learned that it’s glib to expect a data platform to support observability with *just* a TSDB or *just* a transaction/trace/logging DB. And also that “cost profiling and control” is a core platform feature.

4/ But what about “Benefits”? There’s all of that business about Control Theory (too academic) and “unknown unknowns” (too abstract). And “three pillars” which is complete BS, per the above (it’s just “the three pillars of telemetry,” at best).

It’s here.

After months of building, the new, revamped, reimagined Generalist is ready. I can’t wait to show you.

Here’s what it means.

https://t.co/4RaadaUjKR

*How did this get started?*

In August of last year, shortly after going full-time, I decided The Generalist needed a permanent home. Something that captured the vision for all the great things I thought would come out of this community.

I set to work.

You can hear more about building the new site in the tweets below. Of course, if you’re excited to jump straight in, and become a member, you can do so

*What was the plan?*

Launch by the end of September. Here’s the email I sent to The Braintrust (the awesome folks that have agreed to give their advice on this little venture).

- 15K subscribers
- New site
- New membership
- New community

*How did you do?*

I failed on all four.

By the end of September, I had +11K subscribers — 15K had been a stretch, so that was good with me. But I also had no site, no membership, and no permanent community home.

Thread – Dump the Legacy Media; Turn to These News Sources

A. We all need sources less tainted by the Big Tech/globalist narratives that are echoed repeatedly throughout the legacy media. My brother sent me a list of alternatives from the Noq report.

The New York Times article about SlateStarCodex is finally out and it is...bad. There's a lot I could parse, but let me just walk you through one paragraph that is so misleading as to be

Take the first sentence of this paragraph. Now, technically the clause--"who proposed a link between race and IQ"--could simply modify "Murray" and have nothing to do w/ SSC.

But 99% of readers are going to assume that the clause actually defines SSC's alignment with Murray. In other words, the author is strongly implying that SSC shares Murray's racist beliefs.

And that would be big(!)...if it were at all true. It is not. Indeed, if you go to the hyperlink, you'll find that SSC's purported "alignment" has nothing to do with Murray's "Bell Curve."

What SSC & Murray agree about is that poverty is partly hereditable and thus very sticky, so much so that the proposition job retraining programs will meaningfully address mass economic disruption is a pie-in-the-sky fantasy.

Why was @LudwigAhgren's Twitch stream yesterday a masterpiece in creating live content?

Ludwig started off with a high energy intro with background music that sounded like an entrance theme to a WWE wrestler (or a Saturday morning TV show).

He then moved onto a segment where he attempted to break a 'world record' for speedrunning Unban Bingo.

(a trending piece of content right now, with in-jokes with the Twitch community and funny content that can be repurposed for YouTube).

Ludwig follows this up with a 20 slide presentation on 'how to make it big as a streamer'.

He engaged viewers into chat by asking them to vote directly in chat temporarily, which perfectly broke up what could have been a 'boring' presentation (spoiler, it wasn't boring).

He follows this with a Q&A and answers as many questions as he could, again, engaging chat.

THEN.... we get a PogChamp emote tier list of every PogChamp so far.

The vast majority of images are jpegs, which are internally 420 YUV, but they get converted to 32 bit RGB for use in apps. Using native YUV formats would save half the memory and rendering bandwidth, speed loading, and provide a tiny quality improvement. It would also be \

a good path to supporting better video codec still image formats and 10 bit components. You can do it today, but you need to do the color conversion manually in a shader, which can be a big ask for some devs. Defining a FMT_JPEG_YUV that does driver injection akin to the \

external image support on Android could make it much more of a drop-in. Even doing it the hard way seems like it would be worthwhile for web browsers today.

Does artificial anthropocentric intelligence lead to superintelligence?

When I use the term Artificial General Intelligence, my meaning of 'General' comes from the psychology definition of the G-factor that is tested in general intelligence tests.

It is an anthropocentric measure. The question that hasn't been explored in depth is whether a "human-complete" synthetic intelligence leads to a superintelligence. The prevailing assumption is that this expected.

I am going to argue that this assumption may not be true.

The assumption that goes into AGI automatically exploding into a superintelligence is driven by the bias that human intelligence is perceived at the pinnacle of all intelligence.

I posted about the Signal messaging application versus Telegram a while ago, and I received a lot of answers about different applications as alternatives. So I'd like to write a thread giving an overview about my perspective on the security of different applications. 1/53

It's very important to remember that this thread is only about messaging applications for mobile phones, and the evaluations are based on my own perspectives and needs. In some cases they will be subjective, and you should investigate before applying the advice to yourself. 2/53

As I've mentioned in previous, when talking about secure messaging applications, it's extremely important to remember that if an application is secure enough, the limitation will not be the security of the application itself, the limitation is the security of the device. 3/53

When talking about security, the weakest link in a chain will be the one an attacker will go after. There are some applications in this thread that are very secure and have great protocols. But if the device is compromised, that will simply not matter. 4/53

So, if you have something very sensitive to discuss, my strong advice is to not trust that information to a mobile device - there are simply too many ways it could be compromised. So, from that perspective, the security of the protocol is not relevant. 5/53

@zkat__ I'm in the position that I actually find npm / yarn the best ecosystem. Whenever I use something else I always end up stubbing my toe into something thats missing / feels wrong.

Ex. Cargo seems to neither have a concept of devDependencies nor peerDependencies.

I also can't understand why it wouldn't have an "add" command to add a new dependency. And I'm no fan of Toml, json is greate (easy to parse and build tooling around), and the better option in my opinion would be json5.

C / C++ seems to just not have language package managers. The linux / bsd crowd seem to have decided that the system package manager also should be the language package manager. Which might have been fine if every Linux distro used the same system package manager.

Instead we end up with a N x M problem. Where we have a bunch of different operating systems and they all support multiple system package managers. So there's no easy way of distributing, referencing and updating C / C++ packages.

It is also my opinion that the compiler / runtime should be a package dependency. I don't like Rust's split between rustup and cargo (they should have been one tool). Similarly it would be better if you added Node as a dependency to package.json, that way we wouldn't need NVM.

Setting up Git/GitHub to work with R/RStudio can be challenging.

Here's a thread to walk you through the process step by step.

This thread also lives in blog post form. #rstats

Preamble: the best overall resource, and one I rely on extensively, is Happy Git with R by @JennyBryan and @jimhester_.

If you have additional questions about Git/GitHub + R/RStudio, this should be your first

The first step to set things up is to install Git.

Chapter 6 of Happy Git with R lays out the process for Mac, Windows, and Linux users.

I’m on a Mac so Git came pre-installed on my computer. I was able to verify that I had Git installed using the terminal in RStudio.

The next step is to configure Git.

This is covered in Chapter 7 of Happy Git with R , though I show what I believe to be a slightly easier process using the edit_git_config() function from the {usethis} package.

The Fishrot De Klerk Affidavit.

De Klerk starts by saying he deposes of the affidavit without any charge or indictment against him.
He says he knows in his revelations are informing of corrupt practices
he relies on his memory, his phone and computer records

He says all paper files from his office are already with ACC
he concedes that this is evidence of criminal offences to which he may also be implicated in.
He highlights that the PG and ACC can use him as a state witness and he is allowed to ask for indemnity for offences

He highlights that the indemnity is if he coorperates with the Authorities in the Criminal proceedings and asks to be indemified against prosecution for assisting in the case.
He mentions the offences/contraventions he might have commited and asks for pardon from prosecution

Fraud, Contravention of POCA, FIA, ACA and 5 other criminal offences he was involved in with the fishrot accused.
He says his name & images have appeared in the newspapers and it has affected him until hospitalization and now on strong medicine bc of weak emotions and psychology

He mentions that no warrant or indictment are yet against him and he asks for an opportunity to explain his side of the story and how it will help ACC.
Even as a lawyer he says he was duped into doing some peoples dirty work since 2016 as he will explain.
