Unless you think that no attempt should be made to determine the origins of the virus because of what trolls might make of it, I don't see the problem. If you do think that trolls should have that power, it's pretty late to worry about it: the official narrative about it all having started in Wuhan's seafood market has been known to be incomplete at best for a while now:

Ask HN: Recommendations on Learning Philosophy?
Lately, I've gone down this rabbit hole and trying to compartmentalize philosophers with their ideas. Coming from a technical background with little exposure to the field, I find it difficult to draw boundaries around similarities and differences between their ideologies, and who would agree/disagree with another on some topics. What are some good materials to start with?
> The Right Thing is to have the certificate contain a time stamp of when it was issued

Well of course they should, that's why it is right there, called "not before"

> The client should decide whether the certificate is still trustworthy. The cert can contain a recommended expiration date, but the dispositive information should be the issue date.

Well, that exaclty is the case. Most clients decided to honor the recommended expiration date, and Apple just announced they won't.
This may be off-topic, but I've had a passing thought over the years of the evolution of opensource to expand to the blueprints, architecture and building-codes of residential homes to simplify the upfront costs and options of new construction for specific needs (starter homes, bachelor pads, tiny homes,etc).

In the US for instance, could we take all of the local building-codes and design blueprints that would satisfy all of the legal requirements for quality, sustainable construction, regardless of the state, city or county that you choose to build in?

Even going with a smaller scale and offering off the shelf blueprints by state may stimulate more new construction growth and sustainable designs.
Nice article, but the actual intention of building this PC is for Hackintoshing. If this were 5 years ago, I would not choose any AMD CPU for a Hackintosh since they require lots of patches and maintenance to the mach_kernel to recognise and detect the AMD CPU. But in 2020, this has gotten easier and with more good news with the rumours of a AMD CPU powered Macbook, etc.

Choosing an Intel NUC these days is more of a safe bet for a beginner hackintosher to replace a Mac Mini.

I think the reason React isn’t mentioned that much is because of how de facto its dominance has become.

The smaller-community frameworks are mostly interesting because they’re not React (i.e. they purposefully target different scopes, niches). The de facto standard framework for component-oriented front end development has been React for a while now. Typescript (which you see mentioned) complements react, it isn’t a component framework that aims to replace it.

Is there any books, methods that I can use to start talking/thinking more strategically?
It depends on the design. You’re right that all the ones on sale today are trash. You can get vintage ones that are indestructible though.
That's a bit of a Rorschach question and debating it won't get us very far. Two concrete observations we can make (and, if you like, debate):

1. The cost of TLS certificates is now effectively zero.

2. We trust CAs (in an engineering sense) less than we used to; we have near-mandatory Certificate Transparency now to monitor certificate issuance, and the browser vendors will kill a CA that misissues egregiously, as they've done already with the largest commercial CA.

Knowing what we know now about how this stuff works operationally, we probably would not have designed the CA system we did in the 1990s.

I'd say that "marketing" as used here includes a wide variety of activities, much more than actually buying ads and trying to directly sell your product to people.

More like - if you have an idea for a commercial website or app or something, it's best to start by finding potential customers, building relationships with them, and getting to know what they actually need and are willing to pay for. This is much more important than what language and framework to use, how you'll host it, and other technical decisions. Do the research first to figure out if people are willing to pay for your idea in a form that's in your "runway" budget of what you can afford to build and run before you get money coming in.

It's also perfectly fine to build something without that to try out a new tech you think is interesting, or to scratch a personal itch, etc. Just don't expect to bring in any money with it without doing that research.

Would there be a market for cheap, lightweight pdas with weeks of battery life today?
I agree up to a point: There were peoples with their distinct cultures that the Ottomans conquered, the most prominent example being the Balkans. However, "nation" is an 18th/19th century idea. The notion that distinct peoples should form distinct and independent units of state called nations was no driving force in the medieval and early modern period, in which we see the forming of multi-national empires. I think you refer to this as well, I just wouldn't use the word 'nation' in the same way.
I’ve found asyncio to be a very simple model to understand, using the aio libs: aiohttp, aiopg, aiobotocore, etc.

Basically just slap “async” or “await” in front of everything and understand that anytime there is a network connection being accessed, that method will release control of the main thread.

You just have to pay attention to where something might block the thread for any significant amount of time - heavy calculation or lengthy file IO

You can spawn a multitiude of async tasks on startup and have super basic “scheduling” by using asyncio.sleep with some jitter.

The only time I have seen the performance limits of a naive asyncio app reached was in an auth app that sat in front of every API request for the whole company, and even then it was an obscure DB connection pool management issue deep in psycopg2.

I totally consent with this. However, doing as much as we can to reproduce the experience is of some importance. E.g., there has been a basic Spacewar! emulator in Java since 1997, but it only recreated the game on an abstract level, missing the intricacies of the display. Many, including myself, somewhat shrugged their shoulders on this. It has only been, since there have been efforts to recreate the display experience on a more or less analog level that the game is appreciated for what it is, a quite perfect beginning, not to the least for its esthetics. (Disclosure, the web emulation of the PDP-1 running Spacewar! is by me.)

Based on this experience, I'd say, there's need to constantly update emulators to the current state of technical media representation. We are never on the safe side… This will only become trickier as any original hardware and/or media recordings of the software running are lost. Much will be lost in translation, since software has context.
Looks awesome.

ES is good but it takes a small army to keep on top of the performance and management. And then there's the upgrades which will fix a few bugs and introduce new ones too.
I had lot of success with Clickhouse recently for tables that are 200+ millions row and that was with the Log table engine, not the Merge tree one so I would expect it to get even faster when we change.

It's very easy to setup so you should be able to test it quickly to see if it fits your needs.

Thanks yes, this is totally correct -- the FFT uses a Tukey window, which should be able to match the main lobe.

I'll give it a shot (and edit the post.)

You can't declare a read-only map (or slice). Actually Java made exactly the same mistake, the best you can do is to implement Map<K, V> and List<T> with setters that throw at runtime.
Maybe site quality should be a factor - I tried to watch the video and waited roughly a minute before it failed to load. I thought it was an adblocker thing, so disabled it.

On page reload, it was adpocalypse, two pop-under windows, one video playing on the side, and the video still struggling to load with my macbook fans kicking in. The entire site was essentially a giant ad that I never got to see the video and re-enabled adblock.

I'm unsure how sites like this are allowed to exist, or how people even tolerate it.

Step CA (https://smallstep.com/certificates/) is a small, manageable CA designed for private PKI uses, and it now fully supports using ACME to hand out certificates to your endpoints. That means anything like certbot that can speak ACME can pull private certs from a Step-CA instance.

So many things to unpack here, but on a pyschological level, focus on the negative emotions (and hopefully anger) you’re feeling now as you think about why you wrote this post.

I keep going back to the old AT&T phone book fonts like Bell Gothic[0] and Bell Centennial[1] largely because it was designed to be legible at small sizes when using rather primitive printing methods. In a more modern context I find it works really well on charts and whatnot, even scaled down and compressed a bit more[2].

A couple years back I impulse purchased a Google Chromecast at a local Walmart. When I went to open it up at home, the seal looked a bit funky like it had been carefully pealed back and put back in place.

What it contained looked like a Chromecast, but was actually a knockoff, which I never could get to associate with my network or get working.

Apparently someone bought this cheap one online, didn't like it, bought the real one at Walmart and put the fake one back in the box and returned it to the store.

I'm unconvinced that battery life is important for something you use all the time.

Obviously it needs to last a day, but if you're frequently using it, charging it overnight isn't hard to remember.

If you don't often use it, battery life is critical because it's unlikely you'll remember to charge it... but if you're not using your PDA regularly, it's probably not a very good PDA (for your needs, anyway).

I think we all think we want long battery life. I just don't think in practice it matters.

Why do you not support it?
From the combination of store name, item description/template, quantity, other items by the seller, and comparable items. These things are up front and in your face, with each seller having a vested interest in creating a reputation. Once you see the patterns, you don't have to "investigate" each thing, you just get a feeling.

Legitimate distributors generally have recognizable names and other web presences - Best Buy, Adorama, Beach Camera, Anker Direct, Rosewill, etc. The value here is being able to search prices across all these stores at once.

Surplus distributors usually have conditions Open Box / Seller Refurbished, fixed quantities, many such listings.

Knockoffs/generics either ship direct from China, or have basically identical listings that ship directly from China.

This of course all depends on what you're actually buying, but being able to weigh such details is the whole point. Many generic computer cables/adapters/etc are great, but you'd be foolish to buy lithium ion batteries that way.

Specifically searching for "Ove Glove", I do see an item that is direct from China. So right away I know this is an item that has been heavily copied. Which is a given, with this article. But knowing this means I can either opt for the cheaper generic version (and self-verify it has similar utility), or be extra sure to order it from a legitimate channel.
I’d say they scratch different itches. jquery helps you write better js, the same JS you may have been writing for two decades.

React is, from my perspective, an attempt to abstract away a lot of DOM, with the objective of decreasing the size of the solution space to common problems.

The idea is that two engineers working in two different parts of a company would write more or less the same code in react, whereas the jquery solutions would have been very divergent. React enforces patterns and makes it harder to write bad code. That’s the dream, at least!

I wouldn’t compare the two directly, they’re solving totally different problems. Jquery makes writing vanilla JS less verbose. React is more like an engine that’s written in JS and programmable with JS, with the goal of making browser code more composable and opinionated (wrt data flow).

Apple recently (last fall) introduced a change that rejects all certificates that are valid for more than two years, whether they're public or private. I would double-check whether the self-signed certificates are valid for longer (many default self-sign processes make ten-year certs, for instance). Failing that, you may have to create a proper private PKI and get users to install the CA, or else use something like Let's Encrypt for certs.
If you're doing it from the machine where your CA is, and using secure transport, then it shouldn't be less secure than doing the CSR/Sign/Certificate dance.

I mean, it would be nice, especially if you are distributing to other people, but I don't really see a difference if we are talking about uploading cert/keys to servers where you have root access.
Greetings everyone Christian Thornton, Last Year I applied for a loan but proved negative. My goal was to start up a business but due to my bad credit history I was unable get a loan. My credit score was 458 I had lapse in payments from states, so some stuffs went to collections some got charged off some 30/60 day late all credit card got maxed. While I was digging online for possible ways to get my credit fixed, I came across some article talking about this great credit specialist Ghost virus I was impressed. I quickly contacted him to get more understanding how it works we had a chat I was impressed from the details and he gave me. He requested some info from me which I provide, the process lasted for 2weeks they got my credit fixed with an excellent credit score I really appreciate you thanks. If you’re seeing this and you need a credit repair specialist then here’s the man to contact (GHOSTVIRUS7890@ GMAIL.COM +1 205 418 0498)
I am looking at this and thinking, how many times would a typical user need this? I occasionally find myself needing to manipulate excel documents but not enough to want to invest in dedicated software.

Is this meant to support ETL workflows?

Is it possible to create transform recipe packs as part of the product offering? Basically pre-built configuration instead of users doing this. Maybe provide the software for free and sell the recipes?

Is this something you can package as a component that other ETL products could plug into? This can be either native plugins or some kind of web API front-end.

Just spitballing :)

Even if you only let a pinhole of sunlight in, enough to illuminate a surface to 120 instead of 120k, it will burn your retina.

Normal retinal spot burns are not about total light coming into your eye. They're about incoming light per solid angle. A light that is bright enough per area is dangerous at any distance, until it's so so far away it looks like a single point.

I'm sure that there's some level at which total light is damaging, even if there are no super bright spots. But that level is going to be significantly higher than 120k. It's maybe a range this LED can reach, maybe not.
> The BBC iPlayer was streaming video to the whole of the U.K. in 2007.

Exactly. In 2007, The BBC believed that the UK == The World with iPlayer. So no innovation from them happened until a new challenger approached.

I was on holiday in another country and attempted to watch iPlayer shows and access was blocked (and is still blocked) even with a VPN and I used to pay for their TV license at the time. I'm not surprised why many kids these days choose online instead of TV to watch when they want, where-ever they want rather than wait. Also BBC iPlayer programmes still have a habit of 'vanishing' if you wait too long.

The technology was available only in the UK and the BBC was ahead of its time with iPlayer but Netflix said "Thanks for your idea and we're very inspired by the BBC..." and repeated this and made it accessible to the whole world which the BBC is still left wondering why they didn't succeed after getting disturbed by Netflix in 2010.
