I am on a team that has chosen Svelte to replace Riot.js. It has been an excellent experience. We have found that since Riot and Svelte have some similarities in structure and do not use a shadow DOM, we that our old Riot code and new Svelte code co-exist while we build new features and slowly migrate everything.

Our team has diverse experience with the other tools in this space. I would say that the consensus is that Svelte is far more intuitive and fun than other tools.

> Zero universal guaranteed paid sick leave

This is a false statement. There are 12 states which require paid sick leave, amounting to 30% of the population [1]. Federal employees are guaranteed paid sick leave days [2]. According to the Bureau of Labor Statistics, 61% of workers have paid sick leave, 78% have paid vacations, (80%/90% in large employers with 500 or more workers) [3].

That whole section is just political garbage. There's plenty of reasons to believe that businesses will take precautions themselves to limit the spread of the virus internally, which includes offering paid sick leave to encourage people to be extra careful.

Thats some strange logic.

I have multiple racks of company owned bare metal that I deploy to. Still don't want to build a pecl extension. Much simpler and way less likely to not run into random build issues if I can just install via composer.
I was looking at MessagePack for communicating to and from my STM32F1-based microcontroller project from the PC controller software I'd be writing. At least the official C library was not optimized for memory usage and code size. I also considered BSON, but it also lacked suitable libraries.

So I ended up using JSON. Yes the message sizes are larger in byte size with JSON but using the jsmn[1] parser I could avoid dynamic memory usage and code size was small. The jsmn parser outputs an array of tokens that point to the buffer holding the message (ie start and end of key name etc), so overhead is quite limited.

For JSON output I modified json-maker[2]. It already allowed for static memory usage and rather small code size, but I changed it to support a write-callback so I could send output directly over the data link, so I didn't have to buffer the whole message. This is nice when sending larger arrays of data for example.

Combined it took about 10kB of program (flash) memory, of which float to string support is about 50%. Memory usage is determined by how larger incoming messages I'd need, for now 1kB is plenty.

A nice advantage of using JSON is that it's very easy to debug over UART.

Though having compact messages would be nice for wireless stuff and similar, so does anyone know of a MessagePack C/C++ library that is microcontroller friendly?

Some incarnation of "paid sick leave" is likely to emerge [1], though I'm a little pessimistic -- probably would have a sunset clause.

POTUS tiptoed around this yesterday: "We're also going to be talking about hourly wage earners getting help so that they can be in a position where they're not going to ever miss a paycheck." IIUC "Paid sick leave" maybe via tax credit or some other subsidy.

Coronavirus and the Clash of Civilizations
> For those who can't live without a framework: What would you miss?

The thing I miss the most is a good component and state abstraction. That's it.

I would be very happy using ASP.NET WebForms today: components are rendered 100% in the server but the state is persisted by the client using a <input type=hidden> field. The server can be 100% stateless.

Too bad it is impossible to convince anyone to pick up ASP.NET WebForms in 2020 :)

Modern backend frameworks such as Rails and Django have similar "component-ish" helpers, but those always fall short of the capabilities of both React/Vue and ASP.NET WebForms, and you have to worry about state by yourself.

Phoenix Live View is cool, but needs a stateful server, requires JS and polyfills up the wazoo. At this point I'd rather use Vue or React.
There are two options I'm familiar with:

1. Without wondering if you sincerely mean it, make a point to say "thank you." Typically if you are depressed you will be alone, and so it is possible to recognize situations where you took an action now to make something easier for yourself later: for example, doing the dishes now instead of waiting for them to pile up. When that happens, verbally thank yourself on behalf of your future self. If you're capable of doing this, it jump-starts gratitude after a while.

2. Instead of feeling gratitude for things you perceive as positive, look for things that you perceive as neutral. The majority of your sensory experience is neutral. If your emotions are very negative, instead of looking for a dichotomy between negative and positive, look for a dichotomy between negative and neutral. You will perceive that neutral is not-negative. Because neutral is not-negative, increased perception of neutral sensations is a positive. If you perceive neutral sensations as positive for long enough, it jump-starts gratitude after a while.
Because all your existing json will just work, you don't have to change your data representation to support some other format(proto, avro, thrift).

OK, but if compromising SGX is pretty easy, that just leaves the servers (hosted on AWS) for someone to be able to observe and decrypt all Signal traffic, right?

This is awesome, congrats! I love Rails but it does seem like nextjs has left it in the dust in terms of making it easy to build simple, performant front-ends in react and there's no official Rails graphql solution yet either. What next is missing is a blessed omakase way to deploy it with a DB.

Can you talk about or point me to docs on the different philosophies between this and nextjs? In particular next already makes bundle optimization, splitting, lazy-fetching and serverless deploys pretty automatic. Why not start with next and work on incorporating the DB/business logic functionality? Related: why Prisma?

I don't think it's that premature. Making the (big) assumption that serialization format X has good stable support in your language, and has the same expressive capabilities as JSON, you should be able to use it as a drop in replacement (as long as you control both ends of the communication...). And doesn't a huge portion of what we do around here amount to "shuffle serialized data around as efficiently as we can"?
Yes, agreed. Credit cards and hacking discussions are one thing (partly because they can directly affect your company or customers), but child abuse is a totally different matter. In those cases I imagine you should just report whatever you accidentally stumble upon to law enforcement and stay far away afterwards.
It depends on what constraints apply to the data. Any bit pattern could be used for an int, but to guarantee a UTF-8 string it would need to be validated.
JSON is a binary computer-to-computer interchange format. No computer-to-computer interchange format has comments.

The problem with JSON is that it's just human-readable enough that people think it's a config file format. It's not.
Is that really the case? If I'm not mistaken, secure enclaves have a different security model than the use cases you're suggesting: They are so a third party can run software on a user's machine without trusting the user. For example, delivering encrypted drm software to a customer that might be trying to crack it.
It really depends.

Because you craft the training set to add more hard cases.

The trouble with mainstream machine learners is that they're allergic to making their own training sets. If they can't download it from Kaggle, it doesn't exist.

No wonder they (at best) get the same results as everyone else.

It drives me nuts. Consider those digits that LeCunn, Hinton and other have popularized. Every seen somebody try it with a different set of symbols? People assume that the same methods would work with a different set of symbols, but the systematic avoidance of anyone showing that results suggests strongly that it wouldn't work with other symbols.

The "military industrial complex" folks build and use NLP systems every day that are much better than the "state of the art" in NN-based NLP, and it is as much about designing the tasks (e.g. NOT Penn Treebank!) and sculpting training sets as it is anything else.

OK. Sorry for disappointing you.
It is a literally true statement. Universal means covering everybody. That some slices of the population have it in no way contradicts that. Indeed, most of your numbers prove that sick leave in the US is not universal.
I had a similar experience to yours. Divorce. Heartache. Depression amplified by..a lot. Tried to get out. Joined a couple of groups on Meetup.

Didn't work. Moderately enjoyed it. Would get home, then... crash. Back into the spiral.

Fast forward a couple of years. In a better place, somewhat. Try again, what the hell I'm bored and can only play so much HZD and BotW. It was surprisingly better this time. Started making friends. Texting.

Feels good. Better, at least.

So maybe you aren't in a place where that works for you right now. Maybe it will one day. Don't close yourself off to it completely, though. It's helped others, so who knows.

I have struggled with "depression" for decades. Now I'm healed. I went to countless psychiatrists, took drugs and everything. I didn't really help much. I told them I feel bad, they labeled me "depressive" without trying to find out what is really going on. In the the end I had to find it out by myself. The depression was just a symptom. The main cause of it was a social phobia. None of the therapists ever addressed this. Other factors: unforgiveness and my own frustration that I wasn't aware of in many situations. So I started peeling off all these layers. I just didn't really know myself, was so full of inhibitions.

Often depression isn't something you should be afraid of. Neither is it something that you just "have" like a sickness. There may be reasons for the depression and maybe you can dig them out.

I just skimmed the article but what I've read seems to be how to cope with depression, not how to address the underlying issues. Better try to find out where it comes from, if possible.

I've seen that same thing! But I live about an hour away from Seattle, and I'm generally seeing way fewer people shake hands and several people I know (my family included) are avoiding unnecessary trips into public.

I mostly just wonder where the threshold is between population density and social distancing and R0. Obviously total quarantine does wonders, and completely normal behavior is terrible, but is it enough if half the population takes precautions? Or 2/3 or 1/3?

I've been thinking of it kind of like a graph or a web, and if you cut enough of the connections, the spread stops, and "enough" isn't anything like "all," and the more strategically placed the cuts are, the fewer there can be, but it's not easy to figure out exactly how many cuts you need.

This is really awesome! One area I'd recommend looking into is automated scanning of cloud infrastructure templates (Terraform, CloudFormation, Troposphere, ARM Templates, etc.) These get pushed to source control all the time and often contain tons of policy violations.

Much faster serialisation/deserialisation (and a lot less allocations on .NET).

It does support compression, but messages sizes are generally comparable to compressed JSON (YMMV, it will depend on your messages).

I can't get past the paywall, so maybe the article answers this question. But, in case not, one major reason could be margin. If you pay Robinhood $5/month then you have access to borrow money from them to buy stock. The first $1000 is interest free and additional "margin" incurs interest.

When the stock market plunges, some people will see that as an opportunity to buy more stock at a reduced price. If they don't have any liquid funds in their account, borrowing money from the broker is instantaneous (assuming you've previously enabled it). I don't know what happened, but I could see their line of credit getting eaten up very quickly if enough investors decided to leverage their available margin.

If investors sold those shares within two weeks, they could pay back the credit line.

I would be nice to have a taxonomy, or at least a bestiary, of serialisation formats. Tentatively:

Schema-driven no-compromise fast compact binary formats with no cross-version compatibility: Cap'n Proto, FlatBuffers, SBE, ASN.1 PER, XDR, OMG CDR.

Schema-driven binary formats which allow some cross-version compatibility: Protocol Buffers, Thrift.

Self-describing binary formats: MessagePack, CBOR, BJSON, Bencode, ASN.1 BER, Avro (?), Fast Infoset, AMF3.

Self-describing textual formats: JSON, XML, YAML, TOML.

I'm using "self-describing" here to mean simply that you can recover the structure of the encoded data without a separate schema, rather than that you can attach any semantic meaning to it.
