If by application database you mean to the level of an RDBMS then no. It's a key-value data store. You get your CRUD operations, expiry, key listing and the ability to do pagination with keys always returning in lexicographically sorted order. Any relation data you want to have would be using the key prefixes, e.g.: article:1 -> {"user": 1, "content": "..."} user:1 -> {"name": "username"} user:1:articles -> [1, ...]
yep. thats the plan. i will have keys like postid:someid/text postid:someid/author etc. the relation aspect doesnt daunts me. As long as I can have a list/collection as a value, i can define a working schema. I am more worried about if its costlier than normal dbs. and if there are any other gotchas to keep in mind as kv workers have scant documentation.
If you're comparing this to a normal DB, the biggest worry should be that it's not ACID compliant. Definitely something to consider if your data is important. The limitations for KV is listed here: https://developers.cloudflare.com/workers/about/limits#kv
You should also consider how you intend to backup the data as there currently isn't a process to do that outside of writing something yourself to periodically download the keys. This will add to your usage cost depending on what your strategy is, for example, backing up old keys that gets updated vs only new keys by keeping track of the cursor.

#423> it's a great alternative for almost any Golang use case
This is bad shilling even by rust evangelism strike force standards.

Is all math/logic most fundamentally geometry?
Don't think so. Geometry requires space, which has certain features which constrain its properties (sorry for a tautology). If you avoid such constraints, you can still have math, but it doesn't make sense to call it geometry. Looks a bit surprising math definition include concept of space. Geometry looks underappreciated, yes, but to replace the whole math...
To me, the answer here is “kinda but no”. Math in its most basic level is about studying logical connections. Sometimes being able to symbolize something in notation allows inspection of logical objects otherwise unobservable - like higher dimensional objects. But there’s the whole area of mathematical logic. I think I can say Godels incompleteness/inconsistency theorem was only about axiomatic systems with no necessary connection to geometry. Mathematics loves to study logical reductions of things and geometry can certainly be left out through reductions.
There’s something of a geometry/algebra separation in mathematics, too. The last few centuries (?) have tended toward algebraic research at the exclusion of geometry. There’s even reason to believe the two types of reasoning are separated in human brains in so far as people tend to be good at one and less good at the other.

Can this be used to make faster corona virus tests ? If so maybe this is the time to Manhattan project this technology.
Generally, yes absolutely. I’ve been doing a project called “NanoSavSeq” (Nanopore Saliva Sequencing) in my free time. It’s published on dat right now since the raw files for Nanopore are really big (got too big for hashbase). There is one company doing it as well, but my version is completely open source and I’ve optimized it for affordable automation. To give you a sense, you can buy one for 1k and do as much detec…
Would love to know more. This is fascinating.

#426Looks like nix shills are outnumbering rust shills. Pretty bad for us.

#427Hasura + React Admin. Combine Hasura (automatic GraphQL on top of PostgreSQL) with React Admin (low code CRUD apps) and you can build an entire back office admin suite or form app (API endpoints and admin front end) in a matter of hours. This adaptor connects react-admin with Hasura: https://github.com/Steams/ra-data-hasura-graphql
That's really handy to know. Was looking for an alternative to forest admin.

#428Web Assembly It's interesting in a bunch of ways, and I think it might end up having a wider impact than anyone has really realized yet. It's an ISA that looks set to be adopted in a pretty wide range of applications, web browsers, sandboxed and cross platform applications, embedded (into other programs) scripting, cryptocurrencies, and so on. It looks like it's going to enable a wider variety of languages on the web…
Aaah so we have come full circle from Java applets.

#4291. Starship - https://www.spacex.com/vehicles/starship/
Completely reusable rocket that can carry 100 tons into low Earth orbit, refuel, and then continue on to places like Mars. Launches are estimated to cost SpaceX about $2M, compared to the SLS $1B (estimated, similar lift capability) and space shuttle $1B (27 tons). The engines are real, test vehicles are flying (another test launch is likely to happen in the next week or two). Follow the SpaceX subreddit for progress updates
2. Commonwealth Fusion Systems - http://cfs.energy
Lots of reactors have struggled with scale and plasma instability. CFS has adopted a design using new REBCO high temperature superconductor magnets that are stronger and smaller, which can be used to build smaller reactors and better stabilize the plasma. They are building a prototype called SPARC, expected to produce net energy gain by 2025.

I am talking about work being done in clinical trials at reputable medical clinics. They may be mistaken but I don't think it's "silliness." Here is a recent clinical trial evaluating UVBI https://www.tandfonline.com/doi/full/10.1080/2331205X.2019.1... Of course there are many other mainstream treatments that came from somewhat oddball ideas: Sister Kenney's treatments for polio, the Nobel prize winning discovery by…
It should never have been signed off on by an IRB. It is irresponsible and horrific that this has been trialed on people in this century.
Any specific objections to the research links provided?
