    4. Looking for >1Gb/s networking hardware

      I recently got my home internet upgraded to 10 Gb/s. I currently have the following hardware: 10 Gb/s fiber modem (from the ISP) 1 Gb/s ASUS combo router/AP/switch (needs replacement) 2.5 Gb/s 4...

      I recently got my home internet upgraded to 10 Gb/s. I currently have the following hardware:

      • 10 Gb/s fiber modem (from the ISP)
      • 1 Gb/s ASUS combo router/AP/switch (needs replacement)
      • 2.5 Gb/s 4 port switch (not currently in use)
      • 5 Gb/s USB C ethernet adapter

      My ASUS router is the bottleneck in my current setup. My actual internet speeds are more in the 2-5 Gb/s range when plugged directly into the modem. So I'd be happy if I can get 2.5 Gb/s hardware between my laptops and the modem. That makes my existing ASUS router the bottleneck and in need of replacement. Is there a good, relatively cheap, standalone router (no switch or AP) I can build/buy that supports >1Gb/s speeds? Or is there a good all-in-one solution that isn't way too expensive? I'd honestly prefer to have different components each doing just one job.

      I already tried hooking the switch into the modem directly to see what happens. Under that configuration only one device plugged into the switch has internet access.

      I'm going to be building a simple blog for myself.

      Partially I just want something really simple and customizable, and also it will be a fun little programming project.

      I'll be using PHP and mySQL for the backend. I won't be using any sort of framework as it shouldn't be necessary for a very simple blog. I'm fairly comfortable with JavaScript.

      What I'm imagining is some sort of JavaScript library I can just download, link to my html and then turn a textarea into a simple wysiwyg editor. It could be as simple as a markdown editor or something with a little more features.

      It has to be free. Open source would be a plus.

      If anyone has any recommendations or advice I would be very grateful. Thanks!

      I recently discovered how much of a hassle it is to migrate off of Heroku Postgres. Both to keep the user from screwing themselves and as a vendor lock-in mechanism there's no possibility of running an external replica for your Heroku Postgres database. Unless I'm missing something (after a bunch of Googling) it seems like there is a market gap for a tool that allows for a seamless migration away from a Postgres DB that won't allow for replicas.

      I imagine that, given some constraints on what queries you allow on your database, you could proxy connections to a managed Postgres database while feeding them simultaneously to a new database. Starting from a snapshot of the old database one could catch the new database up to a live state of the old database and then swap over all connections to the new one.

      Does such a proxy already exist? I'd love to know as I could use it. If not it might be fun to build and a good side-project.

    17. When should you really use a NoSQL database?

      I've always used Postgres. For a medium-sized app that I work on right now it's running great. Were I to seriously need more throughput I'd either shard (no small task I know) or use CockroachDB (which to my understanding is basically Postgres with built-in sharding and no extension support). Throwing away relationships, constraints, unique compound indices and all of the tools I love that Postgres provides just to get schemaless JSON with high write throughput out of the box doesn't sound like a good deal. But so many people have made the decision to go NoSQL so there must be something I'm missing.

      They ask for years of experience, skills that no Jr would know since, well, it is a Jr and the process to apply for jobs are surreal. Thousands of tests, interviews that goes nowhere and lots of ghosting. And the pay is not that good. No wonder after 2 or 3 years of experience a lot of develpers starts working for companies outside of Brazil.

      Last one to contact me sent me a test to do it in 1 week. I went above and beyond and learned a lot of things. Before this, i had some small projects in Go and Python. Now i needed to learn Docker, tests, github actions, Postgresql and other things. Not everything was mandatory, but i did my best and did it all. I finished in 5 days since i have a day job.

      Here is the result: https://github.com/crdpa/conservice

      Showing the data in the browser was not necessary, but i think it was a nice touch and well made. If this does not land me a job as a junior developer i don't know what else could.

      I'm glad i already have a job in another area, but me and my SO are separated by a 4 hour drive and i'm tired. I want to work from home to be near her and our dog. Paying rent in two places is becoming a burden.

      I would be happy if you guys could test the application i made. It only needs docker.

      And do you guys have any tips from now on?

    20. Do data storage providers 'share' identical data among clients?

      What I mean is, if two clients of a provider upload the same data, do the hosts identify the match and create only references to the identical data for the multiple clients, or do they simply have two copies of the same data on their server?

      Caveat: I am merely geeky.

      What prompted the thought was an article maybe on /. that Russia might run out of data storage, and this would impact entertainment providers. Seems a good way to save space if that's an issue.

      I would guess not, as storage is pretty cheap these days (or was at least in the before times), and it would raise privacy and possibly copyright issues. But a semi-scrupulous and miserly provider might consider it I suppose. Anyone here have any insights or knowledges?

    23. Why store code as text files?

      Code is usually version controlled nowadays in git or some other VCS. These typically operate on text files and record the changes applied to the files over their history. One drawback from this is that formatting of the code can introduce changesbto the files that make no semantic difference, e.g. newlines are added/removed, indentation is altered etc.

      Consistent formatting makes the code easier to read, but the style used is an aesthetic preference. There might be objective reasons for readability in at least the extreme cases, but in many cases the formatting is purely a preferred style.

      If we instead version controlled code in the form of an abstract syntax tree (AST) (possibly even as just a series of transformations on that tree), we could have any formatting we'd like! When editing the code we would just be changing a projection of the AST and when we've made our changes the transformations could be made to the stored AST. If two languages shared the same AST the choice of language even becomes a choice for the programmer. Sadly this has some limitations since ASTs are usually language specific... But we could possibly take this a step further.

      Could we take a compiled binary and use that as the basis for generating an AST? This is essentially what decompilers do. For heavily optimized code this is severely limited, but for debug builds a lot of extra information is retained in the binary that can be utilized to construct a sensible representation. This way of storing code the language used becomes a style preference! Code compiled from one language might become alien when viewed in another language (thinking of lazy Haskell code viewed in C), but maybe that is a corner case?

      There are issues when considering binaries for different platforms. A binary for the JVM isn't the same as one for ARM64 or one compiled to run on an x86. So there are some limitations there...

      One (very) good thing about storing code as text files is the ubiquity of software capable of viewing and editing text. It would however be cool if we could make programming language a stylistic preference that is compatible with other languages! At least the AST part should be perfectly achievable.
